Review: The Role of Human Papillomavirus in Virus-Induced Carcinogenesis

Viral infections contribute to a significant proportion of human cancers, with human papillomavirus (HPV) being one of the most well-established oncogenic viruses. This review summarizes HPV biology, transmission, classification, molecular mechanisms of carcinogenesis, epidemiology of HPV-associated cancers, and current and emerging preventive and therapeutic approaches. particularly HPV-16 and HPV-18, drives malignant transformation through the E6 and E7 oncoproteins, which disrupt tumor suppressor pathways p53 and Rb. Prophylactic vaccination programs have demonstrated remarkable success in reducing HPV-related disease burden, but disparities in coverage remain. Cutting-edge strategies such as CRISPR/Cas9 and RNA-based therapeutics offer promising avenues for treating established infections. Integrating these biomedical advances with robust public health initiatives is essential to ultimately eliminate HPV-associated cancers worldwide (Figure1).

Human Immunodeficiency Virus Drug Resistance (HIVDR) and Baseline Characteristics among Antiretroviral Therapy (ART) experienced Children and Adolescents under the care of Chidamoyo Christian Hospital in Hurungwe, Zimbabwe

Introduction Human Immunodeficiency Virus (HIV) remains a persistent global public health challenge. In 2020, approximately 37.9 million individuals were living with HIV globally, including 1.7 million children <15 years old, with a global HIV prevalence of 0.8% among adults. A larger portion of people living with HIV are found in low-and middle-income countries, and Sub-Saharan Africa (SSA) is home to about 68% of people living with HIV in the world. Strikingly, with increased uptakes in PMTCT, challenges in ART programs, and high viremia among children and adolescents in SSA, the success rate of ART might be quickly compromised, with possible HIVDR emergence, particularly after years of paediatric ART exposure. Therefore, monitoring ART response in children and adolescents in terms of HIVDR patterns and other socio-economic determinants of disease progression might help achieve better treatment outcomes at individual levels. At a programmatic level, this can guide further optimization of treatment options for SSA especially Zimbabwean rural where there is paucity of information on HIVDR prevalence in children and adolescents. Methods We enrolled 89 children and adolescents experiencing virologic failure from Chidamoyo Christian Hospital in Hurungwe. We managed to amplify all the 89 using nested PCR and 32.5% (29) had resistance to at least one ART drug and analysis was done using the 29 samples. Results Among the 89 participants with virologic failure,29 were resistant to at least one of their ART drugs. 39.2% of males and 23.07% of females had HIV-1 with resistance to at least one medication. Among 29 participants with HIVDR mutations, the prevalence of at least one HIVDR mutation to protease inhibitors (PIs), Nucleotide Reverse Transcriptase Inhibitors (NRTI), and Non-Nucleotide Reverse Transcriptase Inhibitors (NNRTI) were 6.47% ,46.76% and 46.76% respectively. Of the 29 participants who had HIVDR 19 (65.5%) had resistance to a drug they were currently taking and they needed to be switched to a better effective ART regimen Conclusion Use of HIVDR testing in guiding and monitoring development of HIVDR at the start of ART or at 1st failure can be very important in treatment options and patient management.

Epidemio-Clinical Profile of Acute Diarrhea in Children From 0 To 5 Years and Prevalence of Rotavirus Before and After the Introduction of the Rotasiil Vaccine in the Democratic Republic of Congo.

Introduction Acute diarrhea remains one of the major health problems in developing countries. According to the WHO, rotavirus contributes to approximately 40% hospitalizations and is the leading cause of severe diarrhea in children 0-5 years old. The objective was to determine the prevalence of rotavirus and the sociodemographic and clinical profile among children with diarrhea in 4 hospitals in the DRC. Methods This study is documentary, retrospective and analytical taking two periods, before and after introduction of the vaccine, i.e. January 2017 to December 2018 and January 2020 to December 2021 in 4 hospitals, i.e. 2 in Kinshasa and 2 in Lubumbashi. Results Total 1872 children, 924 (49.4%) of whom were enrolled before the introduction of the vaccine and 948 (50.6%) after. Only 1737 had performed serology, of which 875 (50.4%) were rotavirus positive and 862 (49.6%) were negative. Positive results, a reduction of 30.6% is noted since the introduction of the vaccine. The predominant age range was 6 to 11 months. The male gender was predominant at 56.7%. Diarrhea was found in 88.5%, vomiting in 73.7% and fever in 73.9%. Before vaccination, the risk was more: 11 times to have diarrhea, 9-10 times the frequency between 3-10 times a day, 9 times vomiting, 2 times fever and 2 times to have a positive result. Conclusion From this study, we note a reduction frequency due to diarrhea unlike previous years, probably attributable to the vaccine.

Postpartum Ovarian Vein Thrombosis After Coronavirus Disease

COVID-19 epidemic, described as a community health emergency by the World Health Organization, began in December 2019. COVID-19 is a source of deep vein thrombosis (DVT) because of hypercoagulation, blood stasis, and endothelium injury complications. This study reports a 26-year-old pregnant woman with coronavirus hospitalized with a left ovarian vein (LOV) thrombosis at Sultangazi- Haseki Training and Research Hospital in Istanbul. Risk classification for DVT disease is of crucial importance for the forecast of coronavirus.

Serum Ferritin Level as a Prognostic Marker of 30 days In Hospital Mortality of Coronavirus Disease 2019 (COVID 19) Pneumonia at World Citi Medical Center: A Retrospective, Observational Cohort, Single Center Study

Introduction The COVID-19 pandemic continues to affect a large swath of the global population. The Philippine records four hundred seventy-four thousand sixty-four (474, 064) confirmed COVID 19 cases since December 31 2020. The COVID 19 pandemic recently highlighted the role of systemic hyperferritenemia as a major cause of death. In this study, we were able to correlate the serum ferritin level and predict 30 day in hospital mortality in COVID 19 pneumonia. Objective The aim of the study is to investigate the correlation between serum ferritin level and disease mortality in COVID19 pneumonia with subset analysis on demographics and co-morbidities of patients with COVID 19 pneumonia. Methodology We reviewed the records of all laboratory confirmed COVID 19 patients from World Citi Medical Center from April 2020 up to April 2021.A statistically significant sample size of seventy nine (79) admitted patients were used in this study. A serum ferritin level was assayed using electrochemilumenescence immunoassay with a Roche COBAS analyzer. Results Result showed that high ferritin level is associated with in hospital mortality. With ferritin level of 1437.07ng/ml, poor clinical outcome and in hospital mortality was considered. We also observed that demographics and co morbidities of patients in this study were significant to predict in hospital mortality. Further sub-analysis of co morbidities such as Hypertensive cardiovascular disease, Type 2 Diabetes Mellitus, Chronic kidney disease, Liver disease, Chronic obstructive pulmonary disease and Cerebrovascular disease showed poor outcome which were directly related to ferritin levels with p value of <0.0001. Conclusion This study has demonstrated that elevated ferritin levels were shown to correlate with 30 day in hospital mortality as well as medical comorbidities such as Hypertensive Cardiovascular disease, Type 2 Diabetes Mellitus, and chronic kidney disease have shown significant evidence for in hospital mortality.

Identify the Effects of Ultra Weak Light on Alphacoronavirus and Vero Cells

Coronavirus is causing many diseases and economic pain to humans and animals. The present study demonstrated how ultra weak lightcause changes in porcine epidemic diarrhea virus (PEDV) and Vero cells. Ultra weak lightactivates Vero cells by lowering pH of maintain media, but have proven no effect of killing the virus.

Molecular Evolution of the Novel Coronavirus SARS-CoV-2

The coronavirus infectious disease (20)19 (COVID-19) pandemic is caused by a newly identified virus (2019) SARS-CoV-2, a beta coronavirus that shares similarities with other human-infecting coronaviruses. Genomic analysis suggests that SARS-CoV-2 is closely related to SARS-CoV, a bat-related coronavirus, RaTG13, and to other pangolin-associated coronaviruses. The spike protein of coronaviruses are glycoproteins and are responsible for attaching the virus to the host cell and entering. Amino acid changes within the spike protein-encoding gene from SARS-CoV to SARS-CoV-2 enable SARS-CoV-2 to form a stable spike protein, to form a stable complex between the S protein and the receptor ACE2, to increase binding points between the S protein and ACE2, and to survive at higher temperatures. SARS-CoV-2 is zoonotic, with genomic analysis implicating bats as the original host and pangolins as the most likely intermediate host to infect humans. As SARS-CoV-2 infects humans, viral point mutations will continually occur and cause the emergence of new competitive SARS-CoV-2 strains. Two major strains include D614G and N501Y and have increased infectivity and transmission, further complicating the scope of the current COVID-19 pandemic. Vigilant monitoring of viral development and evolution is necessary for developing proper treatment methods and vaccine targets.

Chirps Amidst Coronavirus Disease-2019 (COVID-19) Transmission and Prevention in Ethiopia in 2020

Background Ethiopia confirmed its 1st case of COVID-19 on Friday 13th February 2020. The burden increased dramatically by August/2020. The conditions that led to this rise were not reviewed. Objective To exploreCOVID-19 related phenomena in Ethiopia during 2019-2020. Materials and Methods Review of journals, books, and letters to editors, e-sources, news, personal experiences, observations, and communications. Results The zoonotic source of SARS- CoV-2 (Severe Acute Respiratory Distress Syndrome- Coronavirus-2) is not confirmed. The precedent events; and exact mechanism of COVID-19 is not clear. Dynamic models were required on the time line of dynamics of COVID-19; dynamics of infectiousness of COVID-19, and mechanism of transmission of COVID-19. Incubatory carriers might have been missed. Screening based on temperature had been problematic. The time spent in the development of diagnostic test for COVID-19 might have contributed to the early spread. Uninterrupted flights to China during the epidemic by Ethiopian Airlines as well as uninterrupted domestic flights; IDP (Internally Displaced People); and others put Ethiopia (and other countries) at great risk. Demographic adjustment may not be applicable for Ethiopia due to lack of census which had to be conducted every 10 year, was conducted only in 2007. This adds to the problem of error projection. The impact of HIV (Human Immuno-Deficiency Virus Disease) and war in Ethiopia before 2000 might have had affected people who would be now old age and who would be at the most risk of death. This made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. There were also hesitations inconsistencies in case definitions; implementations of quarantine; and burial regulations. Conclusion Even though uninhibited foreign flight to China as well as domestic flights; inconsistencies in the implementation of regulations pertaining to COVID-19 have contributed to COVID- 19 emergence in Ethiopia, the absence of census; the demographic impact of HIV and war before 2000 might have made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. Recommendation Accurate and current evaluation of the impact of COVID-19 in Ethiopia may require the absence of census; demographic consequences of HIV; and war before 2000 into consideration.

Molecular Evolutionary Characteristics of the 2019 Novel Coronavirus (SARS-CoV-2) Contracted by Tunisian Citizens : Comparison and Relationship to Other Human and Animal Coronaviruses Based on Spike Glycoprotein-Coding Gene Sequences Analysis

In contributing to the initiative to address the COVID-19 pandemic and in order to enhance the knowledge on driving forces shaping the evolution of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (isolated from Tunisian patients), a comparison in relation to other coronaviruses infecting humans (SARS-CoV-1, MERS-CoV, HCoV/229E, HCoV/NL63, HCoV/OC43, and HCoV/HKU1) as well as animals (SARS-CoVs in tiger, bats, civet, pangolin, bovine, and MERS-CoV in dromedary/camel), was conducted. In-depth analysis was carried out involving 115 sequences of spike glycoprotein-coding gene extracted from the international databases. Phylogeny inference allowed the reconstruction of a bifurcating tree where four distinct groups were delineated and at the same time, three animal accessions (SARS-CoV-2/tiger, MERS-CoV/camel, and SARS-CoV/bovine) shifted from the animal group and integrated the human coronaviruses clades. Nonetheless, in the presence of reticulate events such as recombination, networks described better the phylogenetic relationships rather than the classic dendrogram. Thus, networks were produced and identified four clusters containing sharply demarcated subgroups (eight subdivisions). Except networked phylogenies of SARS-CoV-1, SARS-CoV-2, and HCoV/HKU1, all the others showed edges and boxes illustrating the occurrence of incompatibilities related to the sequences of spike glycoprotein-coding gene. Thereby and consolidating this result, three methods (RDP package, GARD, and RECCO) were used to detect breakpoints in aligned sequences. Except the clades SARS-CoV-1 and SARS-CoV-2, all the remaining phylogenetic subdivisions were subject to recombination. Furthermore, the screening of selection pressure in all studied sequences by various statistics-based models of the HyPhy package, showed that, similarly, the lineages belonging to the clades SARS-CoV-1 and SARS-CoV-2 were not under selection. In contrast, all members of the remaining clades underwent, to different extents, adaptive selection as well as purifying selection.

Proposition and Practical Significance of Two Classes of New Teaching Methods and Diversified Assessment During the Coronavirus Disease 2019 Epidemic

After entering the new century, people are facing a new external environment. Recently human society is coming into knowledge economy era, and the industrial structure has deeply been adjusted. Today, the past teaching method of imparting knowledge and getting people to accept education, or exam-oriented teaching ideas have been unable to keep up with the needs of the development of the Times. In the future, the key point of education is to promote people to understand the knowledge, and grasp rules between things. Based on this, it is particularly necessary for the talents cultivation to adopt a new idea of training. The paper takes the major in mathematics as an example, designs two classes of new teaching methods CT&CL and BOOF with the diversified assessment to cultivate students’ innovative thinking, providing a reference for the other students. The two classes of new teaching methods and the diversified assessment are worthy of further spreading and exercising during the coronavirus disease 2019 epidemic.

Statistical Analysis on the Influence of Flipped Classroom Teaching on Students’ Learning Effect During the Coronavirus Disease 2019 Epidemic

Currently, many educational practitioners do not agree on how flipped classroom affects students’ learning effect. In order to further explore the impact of flipped classroom on students’ learning effect, this paper conducts a quantitative analysis of some flipped classroom experimental and quasi-experimental studies systematically by means of meta-analysis method. The study finds that the random effect model shows that the combined effect is 0.373, reaching the statistical significance level, which indicates that flipped classroom has moderate positive effect on improving students' learning effect. There is no significant difference in the effect of flipped classroom on the learning effect of different subjects and stages, but the effect on primary school students is weaker. Significant differences in the effect on learning outcomes among different knowledge types have been found, and specifically, the flipped instruction is good for the study of practical knowledge, but has less influence on theoretical knowledge learning. Therefore, in the application of flipped classroom, it is necessary to pay attention to the characteristics of different learning objects and types of knowledge, and flipped classroom teaching cannot be used too much in primary school and the teaching of theoretical knowledge during the coronavirus disease 2019 epidemic.

Covid-19 Virus Sterilization Oven Based on Combination Between Ultraviolet and Infrared Emissions

The world is countering an unexpected wide spread of Covid-19 virus. Among the procedures used to prevent spreading the virus are classical and modern sterilization methods. In this paper, we combine the use of ultraviolet emissions, as a modern method, with the infrared emissions that generates high temperature, as a classical method, to design and implement a sterilization oven. Ultraviolet emissions have the ability to destroy the RNA of the virus while the infrared emissions destroy the virus membrane. Test was performed on indicators contains +ve gram rod bacteria which is stronger than the Covid-19 virus in high temperature and UV emission tolerant. Results showed that the UV emissions killed the microorganism in 15 minutes. However, combination between the UV and IR emissions in a sterilization oven succeeded to kill the under test microorganism in five minutes. The combination between the two sources of emission guarantees an effective sterilization process against bacteria, fungus, and viruses. Moreover, it speeds up the sterilization process time.

Redefining Coronavirus: Update on the Impacts of COVID-19 in the Rural Areas of Abia State

Public health professionals working in rural communities are aware of the health disparities which result from lack of physicians, limited services, and income during the pandemic. Also they are aware that some populations are more vulnerable than others. People in the rural areas are experiencing problems on their physical, social and economic life styles because the pandemic is exacerbating some inequities. Individuals especially women and children in the rural areas are facing barriers in accessing health care services due to lack of resources and availability of health care providers in the communities. With COVID-19, women are less likely to seek services, including sexual and reproductive health services. Such services may be postponed to limit exposure to COVID-19 infection. This is particularly disturbing because in addition to the women maintaining their own health, they are also responsible for taking care of the mental, emotional and physical health needs of their families as well as all domestic responsibilities. As such, women in rural settings face special challenges as a result of these significant roles they play. Therefore, the impacts of COVID-19 are exacerbated on women by virtue of their sex and the roles they play in the family. This is a qualitative study that reviewed the reports of the 36 health care professionals under the aegis of members of COVID-19 committee working in partnership with state government to control, prevent and cushion the effects of COVID-19 in the society. This study is therefore, a summary of the observations of the COVID-19 committee members made up of 10(27.8%) females and 26(72.2%) males. The study focused on exploring how individual lifestyles in the rural areas have been affected in the face of COVID- 19 pandemic by identifying the vulnerabilities in social, political and economic systems which can amplify the impacts of the pandemic. Findings showed that preventive measures like lockdown and social distancing rules, wearing of face mask, hand washing with soap, and environmental cleanliness were not observed. The study noted that health seeking behaviours, sexual and marital life including income, education, employment and social interactions were all negatively affected. Most hospitals were battered and health care professionals boycotted the hospitals for fear of being infected. It was found that lack of health workers in the hospitals caused a good number of individuals to engage in self-medications. Also most pregnant women delivered their babies at home and few with traditional birth attendants. Some of the women who had deliveries at home experienced complications during and after delivery. Unfortunately, the report showed that governments’ financial supports to these women and their family members were insignificant as the government was more concerned with mitigating the spread of COVID-19 than assisting women to have safe deliveries. Therefore, the vulnerable groups especially women, children, and the elderly who experienced threats to their safety and wellbeing as a result of the services that were disrupted during the pandemic, should be assisted so as not to lose their lives to preventable diseases.

Coronavirus: A Practicing Veterinarian Prospective

COVID19 is posing threat cosmopolitically encompassing more than 200 countries and making threat to entire population globally as pandemic. The cats, dogs and bovine are at threat which are close partner to human population. The veterinarians specially practicing are at risk when they encounter the sick animals. This study focus to the Pakistani veterinarian where animal population is under estimated or sometimes census is not performed. As Current population of domestic animals in Pakistan consist of 23.34 million buffaloes, 22.42 million cattle, 24.24 million sheep, 49.14 million goats, and with a huge population of dogs and cats without official census which may pose a threat to innocent population and even more a practicing veterinarian and veterinary paramedics are more at threat, if god forbids. There is need for further investigation its role and zoonotic perspective. Regarding practicing field veterinarians fighting without weapons against mass destructing pathogen and making vulnerability on wide.

The Reopening of Schools and Adoption of Universal Wearing of Face Masks in Anticipation of Sustained Transmission or the Second Wave of COVID-19 with the Influenza Virus

The Covid-19 pandemic has swept rapidly from Wuhan, China to the entire globe in less than six months, infecting over 7 million people and claiming the lives of over 500,000. In the United States, greater than 2 million individuals have become infected and over 110,000 people killed. With no evidence of slowing of the coronavirus that causes Covid-19, public health authorities must prepare for possible sustained transmission of Covid-19, or a second wave into the Fall 2020, but with the presence of the influenza A virus. In the Fall 2020, schools will reopen from kindergarten to 12th grade. Dual pandemics or epidemics will result in high morbidity and mortality not observed when either virus was solely active. Community leaders, educational administrators and public health systems must be prepared for simultaneous outbreaks of both Covid-19 and influenza. Although there are no clinical studies that have evaluated the benefits on the use of face masks during an epidemic or pandemic, public health non-pharmaceutical intervention (NPIs) measures should include the routine use of face masks during school sessions. Using face masks with other NPI may interrupt viral transmission as it has been established that respiratory viruses, such as Covid-19 and the influenza virus are transmitted via respiratory droplets, aerosols, and environmental surface contact.

New Approaches in the Treatment of Covid-19 Virus

By increase the incidence of infection of coronavirus disease 2019 (COVID-19), diagnostic factors for early identification of high-risk individuals are important. On the other hand, more infections are in older patient, comorbidities, and male patients. Identification of components that related to severity of COVID-19 contributed to ACE2 and TMPRSS2 genes, which are critical for viral infection. It was found that adding enzyme copy, hrsACE2, lures the virus to attach itself to it instead of the actual cells… It inhibits the virus from infecting the cells in the lungs and other organs.

The Novel Coronavirus 2019 (COVID-19): A Narrative Review

One of the key steps in determining how to prevent the viral disease is to identify the virus. The virus lives in different ways and in different environments. It lives in the air, in the sea, on plants, animals and objects and humans. Some people put humans on the path of developing zoonotic diseases that are specific to animals but also involve people with unhealthy behaviors. In the food chain, each animal is hunted by other animals and feeds on other animals or plants and other objects. Bacteriophages are viruses that kill bacteria. And there are creatures that kill viruses and this is the biological struggle with viruses. When the virus enters the body, it performs a series of activities that lead to a series of symptoms in the patient. These symptoms include the behavior of viruses. These are among the ecological and behavioral characteristics of viruses that need to be fully understood in order to limit viruses and deal with epidemics and pandemics. In this study, we try to reach a conclusion by reviewing the articles that have information about the behavioral (signs and symptoms) and ecological characteristics of viruses and use these findings in order to combat viruses.

SARS-Corona Virus-2 Origin and Treatment, From Coffee to Coffee: A Double-Edged Sword

Identifying the epidemiological characteristics of COVID-19 disease will help to make appropriate decisions and thus control the epidemic. Although many details, such as the source of the virus and its ability to spread between people remain unknown, an increasing number of cases show the signs of human-to-human transmission. The purpose of this review is to introduce the reservoir hosts, and the possible role of distributions of bat coronaviruses in China, and eventually to aim to predict virus natural hotspots and their cross-species transmission potential. Why bats can maintain coronaviruses long-term without showing clinical symptoms of diseases and what is allowing bats to have a higher tolerance against viral diseases. We need to unveil the mystery of unique bat immunity. Although bats are not in close contact with humans, spillover of viruses from bats to intermediate animal hosts like civet is thought to be the most likely mode to cause human infection. It appears that the coffee beans which are a rich source of chlorogenic acid are acting as a reservoir host and causative agent, and at the same time as a defense agent to create resistance in the consumers (bats and animals). It is assumed that the intake of chlorogenic acid should be capable of protecting human from contamination or severe morbidity.

Using Human Development Indices to Identify Indicators to Monitor the Corona Virus Pandemic

Introduction The Corona virus (CoVID-19) pandemic has hit the most developed countries and has thence spread to inflict other countries around the world. It is the first pandemic that appears in countries not linked to poverty and poor hygiene. Aim To study the relationship between human development and the pattern of the pandemic caused by the CoVID-19 and to identify development indicators that can be useful in monitoring the pandemic. Methods Data collected included confirmed cases of CoVID-19 by country, number of cases that recovered and cases that died and population density per million in this particular country. The data for this information was obtained from the online data on the daily reports on CoVID-19 from the different countries. Data for the Human Development index (HDI) and the ranking for each country were obtained from the most recent United Nations Development of Populations (UNDP) report for 2019. We analyzed data for 166 countries for which the HDI was available for the date of cases reported online on 27th March, 2020 at midnight. Findings There were significant differences by ANOVA for the confirmed cases of CoVID19 cases and total cases per one million population between the countries in the 4 tier group of Human Development. HDI was significantly correlated with confirmed cases, case density and cases that died from CoVID-19 (P<0.01) for all countries but the significance decreased by tier group. Country ranking was inversely correlated with confirmed cases of CoVID-19 (r-0.25 at P=0.001), CoVID-19 cases per million (r-0.4 at P=0.000) and cases that died from CoVID-19 (r-0.2 at P=0.03). Recovery was not inked to HDI or country ranking. The upper HDI tier groups (very high, high and medium) showed significant correlations with total cases per one million population P<0.05, but no correlation was found with confirmed cases or cases that died or recovered from CoVID-19 P>0.05. Conclusions Total cases of CoVID-19 per one million population seems to be a better indicator of the pandemic. The pattern of spread is closely linked to industry.

Medical Concepts with Clinical-Epidemiological Implications that have to be Re-Assessed Since the Coronavirus Disease 2019 (Covid-19) Pandemic

The coronavirus disease 2019 (COVID-19) pandemic is something new that baffles us. The dominant health model and the theory that supported it until before COVID-19 are refuted or invalidated by observing the current tragically situation, which also implies lasting changes in that new medical model. Consequently, once the urgency of the epidemic is over, the conceptual and organizational building of medical care can no longer be rebuilt in the same way. Based on the COVID-19 experience, it is necessary to rethink what kind of knowledge can emerge. Some of the concepts with clinical-epidemiological implications that have to be re-evaluated since the COVID-19 pandemic are: 1. Large epidemics or changes do not arise from an event similar to the "Big Bang", but rather they develop slowly and underground, so a surveillance system must be instituted; 2. Re-evaluate what we understand by "evidence-based medicine"; 3. Patient-centered care is inadequate and must be replaced by community-centered care; 4. Telecare and changes in the organization of consultations; 5. Hospitals and health centers are "biological bombs" that act as vectors of disease and must change their architecture, organization and use; 6. The end of the nursing home model; 7. Change of habits; and 8. Social media can democratize information and help communities organize.

RETRACTED: Recent New Results and Achievements of California South University (CSU) BioSpectroscopy Core Research Laboratory for COVID-19 or 2019-nCoV Treatment: Diagnosis and Treatment Methodologies of “Coronavirus”

Coronavirus nanoparticles show a strong peak of Plasmon absorption in ultraviolet–visible zone. A strong interaction exists between the surface of Coronavirus nanoparticles and Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406). Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) cause to aggregation of Coronavirus nanoparticles linked to DNA/RNA and hence, lead to widening of peak Plasmon of Coronavirus nanoparticles surface at 550 (nm) and emerging a new peak at higher wavelength. In the current project, this optical characteristic of Coronavirus nanoparticles is used to time investigate of interaction between different Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) and Coronavirus nanoparticles. The results were shown that Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) with shorter chain length interact faster with Coronavirus nanoparticles. Therefore, a simple and fast method for identification of Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) with various chain length using red shift in surficial Plasmon absorption is presented.

Urgent Prevention of Corona Virus Disease 2019 (COVID-19): Chinese Eating and Mask-Wearing Cultures

Chinese people have a very good mask-wearing culture; it is normal to wear masks to protect their faces from wind and pollution. Thus, they easily accept the wearing of masks to prevent infectious diseases, as seen with the Corona Virus Disease 2019 (COVID-19) in China today. However, Chinese people have a dangerous eating culture: they share foods or soups from the same bowls and pots using their personal chopsticks/spoons and emphasize loud talking when eating at banquets or at homes. We think this eating culture has raised the infection risk of COVID-19 from person to person by contamination. Therefore, in this paper, we propose models to elucidate how people are infected with COVID-19 through droplet transmission when eating with Chinese cultural context to address the urgent need to change Chinese eating culture; we believe these study models can help not only the Chinese people, but also other national people, to raise mindfulness of public health, prevent COVID-19 and other infectious diseases, at the present pandemic and in the future.

Role of Tie2, CD14, Angiopoietin as Angiogenetic Markers in Hepatocellular Carcinoma Complicating Hepatitis C Virus Infection

Background Identifying biomarkers for early detection of hepatocellular carcinoma (HCC) remains quite challenging. In this study we aimed to estimate the number of TIE2-expressing monocytes (TEMs) cells, which display pro-tumoral activities and are defined as CD14+, TIE2+, and angiopoietin-2; and its potential use as a possible diagnostic marker in HCC patients complicating HCV induced cirrhosis. Methods Current study was conducted on 112 patients. They were divided into two groups: Group I (78 patients) with HCC complicating HCV induced cirrhosis; and group II chronic hepatitis C patients (34 patients). Both groups were compared to (age and sex-matched) healthy persons as group III (38 persons). Result The number of the circulating TEMs: CD14+ and TIE2+ monocytes were significantly higher in the peripheral blood of HCC patients than HCV LC patients and healthy controls, sensitivity and specificity for HCC diagnosis were respectively: CD14 (89.7%, 83.3%), TIE 2 (76.9%, 83.3%), and Ang-2 (76.9%, 66.7%). Moreover, analysis of the P-value and the odd’s ratio showed that CD14 has the highest predictive value for HCC. Conclusion Our results suggest that TEMs and Ang-2can be used as diagnostic markers for HCC, especially among the high-risk group of patients.

Nutritional Care for Patients with Ebola Virus Disease in Ebola Treatment Units – Past and Current Experiences from Practitioners

Background In November 2014, the World health Organization (WHO), in collaboration with United Nations Children's Fund (UNICEF), and the World Food Programme, produced interim guidelines (iGL) on providing nutritional support to patients in Ebola treatment units (ETUs). They have been translated into French and issued by the Ministry of Health, UNICEF and WHO in adapted versions to be used in the current outbreak in the Democratic Republic of the Congo (DRC). This paper evaluates the use and usefulness of the 2014 iGL in the West Africa and current DRC Ebola virus disease (EVD) outbreaks and identifies experiences and lessons learned from practitioners on the operational aspects of nutritional care and support in ETUs. Methods Key-informants (n=26), from 12 organizations (Non-Governmental Organizations, United Nations, Red Cross Red Crescent Movement) were interviewed who were actively engaged in the nutritional and/or clinical care of EVD patients. Results There was a consensus among key-informants that the 2014 iGL initially served a guiding purpose. However, the vast amount of learning from the 2014-2016 and current EVD outbreaks indicates that the interim guidelines need to be revised. Practitioners struggled to find operational solutions for nutritional care, and the challenges were plentiful, especially regarding 1) the different perceptions of the importance of nutritional care among ETU staff; 2) the difficulties around food preparation and distribution for EVD patients; 3) how to take into account the patients’ dietary preferences; 4) the nutritional care needed in relation to specific EVD symptoms; 5) who assumed roles in nutritional care in ETUs; 6) if and how feeding support was organized; 7) whether malnutrition needed to be addressed and how; and 8) whether the intake of specific nutrients could contribute to improved treatment outcomes.  Information from the key-informants interviews resulted in numerous lessons learned and recommendations for nutritional support during current and future outbreaks. Conclusions This investigation underscored the importance of documenting experiences of practitioners on nutritional care in emerging infectious diseases for which limited scientific evidence exists and for which interim guidelines are produced to fill in knowledge gaps. It also emphasized the importance of nutritional care in ETUs during treatment.

Is the Measles Virus Indeed Involved in Carcinogenesis? – Commentary

Objectives: An association between the measles virus and Hodgkin lymphoma has been disclosed by our laboratory in Beer-Sheva, starting in 2003. We question the refutation of our study and the absence of interest among experts. Methodology: It was based on immunohistochemistry with commercial, as well as experimental anti-measles antibodies. It relied also on RT-PCR and in situ hybridization evidence of measles virus RNA. Key Results: At this stage (2004), the link between the virus and the lymphoma was essentially descriptive. The first and last response to our challenge appeared in 2007, in the form of doublet articles, in the same issue of a major cancer journal. The two European research groups responding, rejected categorically our findings by proposing different arguments. Major Conclusion: As reservations to these reactions became soon apparent, a series of papers from our laboratory were published. These articles concerned the evidence of a relationship between the measles virus and additional categories of cancers. Different malignancies in which this virus was not expressed at all, were also described. A further study suggested a mechanism by which the measles virus may activate lymphomagenesis in classic Hodgkin lymphoma. To our dismay, and in spite of repeated calls to verify the various results, no further response was obtained from international experts.

Squamous Cell Carcinoma of the Conjunctiva (Scc) and Human Immunodefisciency Virus (Hiv): What Reality in Ivory Coast Through 23 Cases?

Introduction: Squamous cell carcinomas of the conjunctiva (SCC) are rare neoplasia but have a high rate of increase and a high rate of mortality, especially when they occur in the context of Human Immunodeficiency Virus (HIV) infection. The objective of this study was to establish an epidemiological and clinical profile of SCC in patients living with HIV and to assess its evolutionary characteristics. Patients and Methods: this was a descriptive cross-sectional study carried out over a period of 5 years in the ophthalmology department of the University Hospital of Treichville. The data collected focused on epidemiological, clinical, pathological, therapeutic and evolutionary elements. Twenty tree eyes of 23 patients were examined during this period. Results: The average age of our patients was 45 years with extremes ranging from 31 to 60 years. A female predominance was observed with a sex ratio of 0.92. The average consultation period was 18 months with extremes ranging from 6 to 60 months. Physically, 35% of our eyes (08 eyes) presented a functional loss of the eye. All our patients had a HIV positive status with 16 cases of HIV1 infection, 4 cases of HIV 2 infection and 3 cases of HIV 1 and 2 co-infection. Lymphocyte typing was performed for 15 patients out of the 23 With CD4 cell counts ˂ 200 in 30.43% of cases, between 200 and 500 in 34.78% of cases. All our tumors had had biopsy excision with pathological examination. A postoperative adjuvant topical chemotherapy in 6 cases. The average follow-up period of our patients was 29 months. In all cases, it was invasive differentiated squamous cell carcinoma. Discussion: HIV infection is a risk factor for the occurrence of conjunctival squamous cell carcinoma, but it is also an aggravating factor especially in the case of low CD4 cell count, particularly in sub-Saharan Africa, where the fight against infection, although boosted in these recent years, is far to achieve all objectives Conclusion: HIV seroprevalence is very often associated with opportunistic infections which include carcinogenic processes such as squamous cell carcinomas of the conjunctiva

Advanced Virological And Clinicopathological Studies On Cattle Suffering From Foot And Mouth Disease Virus

Some strains of Foot and mouth disease virus (FMDV) are endemic in Egypt. The present study was performed on cattle and buffaloes (ages: 3 months up to 1.5 years old, of years 2015 and 2016), which were suffering foot and mouth disease (FMD). Sera and tissues samples were tested by different techniques including serum and virus neutralization tests (SNT, VNT), virus isolation and identification by tissue culture methods, Enzyme linked immune-Sorbent Assays (ELISA); and by the pathological and hematology techniques. The results showed the predominance of FMDV serotype O with the presence of serotypes SAT2 and A. The results showed the pathologic picture of FMD was similar regardless its specific subtypes, as apparently the studied strains produces same pathological and hematological changes. Microscopic examination reveals severe hydropic degenerations and necrosis in most affected organs, accompanied by significant changes in blood parameters which indicate severity and direct effects of FMDV on the hematopoietic system. These findings indicates the mode of pathogenesis of FMD virus in its way to exhibits the characteristic symptoms of illness. However, the investigation showed the presence of FMDV type O, A and SAT2 in the studied areas of delta governorates. It is important to focus on producing of vaccines which have only these serotypes as solution to get rid of the endemic behavior of FMDV in delta of Egypt.

Natural Infection by H1-Like Influenza a Virus in South American Camelids from Argentina: Serological Evidences.

Serum samples from wild and domestic South American Camelids (SAC) from Argentina, collected before (2008), during (2009) and after (2010) the 2009 H1N1 influenza pandemic were tested by hemagglutination-inhibition assay (HIA) to evaluate the seroprevalence of antibodies (Ab) against different subtypes of influenza A viruses: A(H1N1)pdm09, A/sw/Argentina/SIV/2009(H3N2) and A/eq/Argentina/97(H3N8). For A(H1N1), an ELISA using a recombinant H1-hemmaglutinin from a reference strain (HA0 PuertoRico/8/1934) was also conducted. Serum samples from Guanacos (126), vicugnas (21) and llamas (100) from Jujuy, Mendoza and Río Negro provinces were analyzed; no clinical signs of respiratory disease were detected, reason for which no nasal swabs were obtained. No seropositive reactors to H3N2 nor H3N8 variants were detected, nevertheless high incidence of Ab reactive to A(H1N1)pdm09 were found by HIA; results which were confirmed by ELISA. The Ab seropositive animals to H1-like IAV found in llamas from Jujuy, and Mendoza (2009) were 78% and 86% by HIA and ELISA, respectively. Thirty-seven samples taken over the three years from guanacos kept in captivity in Rio Negro showed 62% of seropositive animals, while wild guanacos from Mendoza sampled in 2010 showed 36% seropositive animals to H1-like IAV, by both techniques. Finally, wild vicugnas from Jujuy, sampled in 2008 showed 38% and 52% seropositive animals to H1-like IAV by HIA and ELISA, respectively. Our results could indicate the potential role of these species as a reservoir of this zoonotic viral agent of high impact in Public Health, and may suggest that SAC populations might have been infected with an influenza strain antigenically related to H1 IAV. . Surprisingly, for llama and guanaco populations sampled over time in Jujuy and Río Negro, respectively, the HIA and ELISA geometric mean Ab titers (GMT) for 2008 were significantly higher than the ones of 2010. In addition, HIA and ELISA Ab titers found in domestic llamas were significantly higher than those detected in wild vicugnas sampled during that year (2008) in Jujuy. New field campaigns are in progress to collect serum samples and nasal swabs in order to isolate and characterize the virus responsible for triggering H1 reactive Abs. These findings remark the need to better understand the dynamics and ecology of influenza A virus within Sacs populations.

Association of Epstein-Barr Virus with Gastric Carcinoma among Sudanese Patients

Background: Gastric cancer (GC) ranks as the fourth most common cancer and the second leading cause of cancer deaths worldwide. Epstein-Barr virus is a well-known oncogenic virus, it is responsible for 10% of gastric carcinomas across the world. The aim of study was to determine the prevalence of EBV associated with GC in Sudanese patients. Method: Fifty Paraffin embedded blocks of gastric biopsy specimens diagnosed as gastric carcinoma were collected from Soba university hospital and Ribat teaching hospital, Khartoum, Sudan. DNA was extracted from the paraffin-embedded tissue, and then Epstein-Barr virus gene was detected by polymerase chain reaction (PCR). Result: Among the gastric biopsy specimens 27 (54.0%) were of male and 23(46.0%) were of female. Eleven EBV positive samples were found in gastric carcinomas (22.0%), 8 (72.7%) were of male and 3(27.2%) were of female. The mean age of the patients was 56 years, the most positive cases were between 50-59 years old, and (10%) of them are alive in Khartoum. Conclusions: There exists an association between EBV and gastric carcinoma in some Sudanese patients.

Investigations of Molecular Evolutionary Mechanisms in Partially Sequenced Heat Shock Protein70 Homologue-Coding Gene of Olive Leaf Yellowing-Associated Virus Isolates from Tunisia

Reverse Transcription Polymerase Chain Reaction (RT-PCR) using new designed primers pair for Heat Shock Protein70 homologue (HSP70h) of Olive leaf yellowing-associated virus revealed 667 amplified product of 10 olive accessions collected from various olive-growing regions in Tunisia. Amplicons were cloned and sequenced. The sequences were deposited in the international databases. Pairwise sequence comparisons among 10 Tunisian isolates along with a reference sequence (AJ440010) extracted from GenBank revealed a nucleotide identity of 86.06-99.40 and an amino acid similarity of 91.89-99.55. Sequence multiple alignments were searched for evidence of recombination using three methods, ie. Differences of Sums of Squares (DSS) implemented in TOPALi v2.5 software and Single Breakpoint (SBP) along with GARD, a genetic algorithm, both incorporated in HyPhy package. All used methods pointed out the presence of putative breaking points in partially sequenced HSP70h-coding gene. Since failing to account for recombination can mislead the phylogeny inference and can elevate the false positive error rate in positive selection assessment, the use of GARD resulted in the reconstruction of different phylogenies on the left as well as on the right sides of putative recombination breaking points, and the 11 accessions were distributed into at least three clusters compared to MEGA6 software which delineated only two clades. Nonetheless, by dividing the aligned sequences at breakpoints into separate sequence sets, MEGA6 delineated a clustering pattern different from the former two. As a result, recombination reshuffled the affiliation of the different accessions to the clusters. Analysis of selection pressures exerted on HSP70h encoded protein using different models (SLAC, IFEL, FEL, REL, PARRIS, FUBAR, MEME, GA Branch, and PRIME) taking into account recombination, and implemented in HyPhy package, revealed that it underwent predominantly purifying selection as confirmed by Tajima’s D, Fu and Li’s D and F tests, and SNAP algorithm. However, a few sites were also under positive selection as assessed by various models such as FEL, IFEL, REL, MEME, and PRIME.

Pattern of Use of Highly Active Antiretroviral Therapy Regimens and Pattern of Occurrence of Adverse Drug Reactions in an Indian Human Immunodeficiency Virus Positive Patients

Background: In India, Human immunodeficiency (HIV) infected patients with highly active antiretroviral therapy (HAART) are at higher risk of developing adverse drug reactions (ADRs). Objectives: The aim of this study was to characterize the pattern of use of HAART, occurrence, incidence, severity and causality of ADRs to HAART in Indian HIV positive patients. Methods: This was a prospective observational study conducted between August 2009 and May 2012. Enrolled HIV positive patients were intensively monitored for ADRs with fixed dose antiretroviral therapy as per National AIDS Control organization (NACO).World Health Organization (WHO) definition of ADR was adopted to detect ADRs to HAART and classified based on WHO adverse reaction terminologies. Naranjo’s scale was used for causality assessment of ADRs. Preventability was assessed using Thornton and Schuman criteria and severity was assessed using the modified Hart wig and Siegel scale. Pattern of ADRs was assessed with patient demographics, ADRs characteristics, and pattern of drug and reaction characteristics. P-value <0.05 was considered as statistically significant. Results: A total of 426 ADRs to HAART were evaluated from 1982 HIV positive patients during the study period. The overall incidence of ADRs to HAART was 21.4%. Significant difference was seen in the incidence of ADRs in the age group of 41-60 years (p <0.001), CD4+T-cell counts of 350-500 cells/µl (p <0.001), females (p <0.001). Three fatal ADRs of with cutaneous drug eruptions of Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) was 1.1%. Anemia (31.7%) accounted for majority of the reports followed by vomiting (15.5%), skin rash (12.9%) and peripheral neuropathy (10.7%). The suspected drug was withdrawn for the management of the ADRs in majority (27.9%) of the reports. Higher incidence rate of ADRs was noted with lamivudine (3TC) + nevirapine (NVP) + stavudine (D4T) (22.9%). In, naranjo's causality assessment, majority of the ADR reports were rated as possible (69%). Symptomatic treatment for ADRs was given in 91.8% of the reports and 86.4% of the reports the patient recovered from the suspected adverse reaction at the time of evaluation. Conclusion: In India, occurrence of ADRs to HAART in HIV infected patients was found to be higher with zidovudine induced anemia (31.7%). The higher percentage of ADRs to HAART was seen with female patients, age 41-60 years; CD4+ T-cell counts 350-500 cells/µl. Physician must focus for monitoring all lab investigations for early detection and prevention of adverse effects associated with HAART.

Evaluation of Direct Cost of Adverse Drug Reactions to Highly Active Antiretroviral Therapy in Indian Human Immunodeficiency Virus Positive Patients

In India, interruptions to highly active antiretroviral therapy (HAART) are due to adverse drug reactions (ADRs) and no reports on the direct cost incurred in the management of ADRs to HAART are available. There is a need to study direct cost incurred with ADRs to HAART to explore the high economic cost burden imposed by ADRs to HAART in HIV/AIDS patients. This study was aimed to evaluate the direct cost incurred in the management of ADRs to HAART in Indian HIV positive patients. This prospective study was conducted at a Medicine department in a South Indian tertiary care teaching hospitals were ADRs reporting system exist. HIV-positive hospitalized in-patients were identified and intensively monitored for ADRs to HAART. The World Health Organization (WHO) probability scale was used for causality assessment of ADRs. Modified Hart wig and Siegel scale was used for severity assessment of ADRs.Pearson chi-square test identified association of mean direct cost between ADRs and without ADRs by investigating total mean direct cost. The overall direct cost per ADRs to HAART was found to be higher in the context of expenditure on health care cost in India.

Characterization of People Receiving 2-Drug Regimens (2DR) for HIV Management in Italy

Objective To describe the clinical features and real-world treatment of people living with human immunodeficiency virus (PLHIV) using fixed-dose or free combinations of 2-drug regimens (2DR) of antiretroviral therapy (ART). Design Italian retrospective cohort study. Methods Data were extracted from PLHIV who initiated or switched to 2DR: Group 1 (fixed dose), Group 2 (free combination). Results Group 1 was younger and more predominantly male, and had shorter time from AIDS-defining diagnosis to 2DR-ART and from diagnosis to baseline, a lower prevalence of resistance, and fewer comorbidities than Group 2. Median baseline viral load was <50 copies/mL in both groups, but Group 1 had a higher mean due to outliers. The most common ART classes before switching to 2DR were Integrase Strand Transfer Inhibitor (INSTI)-based (48.97%), Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI)-based (22.73%), and Protease Inhibitor (PI)-based (16.53%). Distribution varied: Group 1: INSTI-based (53.13%), NNRTI-based (24.31%), and PI-based (15.04%); Group 2: INSTI-based (29.41%), PI-based (23.53%), and NNRTI-based (15.29%). After switching, Group 1 was on dolutegravir/lamivudine (79,33%) and dolutegravir/rilpivirine (20,67%); Group 2 mostly on INSTI-PI (52.81%), followed by NNRTI combinations, mainly with doravirine (19.10%). Duration of ART after switching was shorter in Group 1. Conclusion Italian PLHIV on 2DR fixed-dose combinations were younger, virologically suppressed individuals at baseline, with a shorter lead time from diagnosis, lower prevalence of resistance and lower comorbidity rate compared to those on free combinations. These findings underscore an unmet need for 2DR fixed-dose combinations, as the free combinations were predominantly utilized for more challenging populations.

Recruitment Strategies and Challenges in a Pilot HIV Prevention Study among Cisgender Black Women in Houston, Texas

Recruitment for research studies focused on communicable diseases such as HIV (Human Immunodeficiency Virus) has historically been challenging, particularly among populations who have been underrepresented in media messaging, yet maintain a significant vulnerability to new HIV cases, like Black women. This study examines the recruitment strategies utilized in Aim 2 of pilot study at the University of Texas Health Science Center (UTHealth) in Houston, Texas that was funded by the Ujima Mentoring Program to develop, implement, and evaluate a video log (vlog)-based intervention. The overarching goal of the pilot study was to promote the uptake of pre-exposure prophylaxis (PrEP) among cisgender Black women in Harris County, Texas. Aim 2 involved the creation of a culturally relevant vlog for use in Aim 3, which sought to educate and motivate participants to consider PrEP as an HIV prevention strategy. With the growing role of digital platforms in public health outreach, social media was employed alongside traditional recruitment methods such as flyers and word-of-mouth referrals. Despite an expanded online reach, engagement remained low, and participation rates did not increase proportionally to the number of individuals who viewed recruitment materials. The reluctance to participate was largely attributed to stigma surrounding HIV and concerns about being publicly associated with an HIV prevention study based on participants feedback to the research team. Even the availability of research incentives to encourage participation did not significantly improve recruitment accrual goals, particularly among healthcare providers who experienced limitations with eligibility due to institutional policies. This study underscores the need to better understand the social and cultural barriers that prevent Black women and healthcare providers from engaging in HIV prevention research. While digital recruitment strategies can enhance visibility to a larger audience, they must be supported with trust-building efforts, community partnerships, and culturally competent messaging to encourage meaningful participation. These findings point to the critical need for multi-faceted recruitment strategies that go beyond social media campaigns and actively build trust within communities, ensuring that HIV prevention research and interventions are both accessible and culturally resonant.

Predictors of COVID-19 Vaccine Uptake Among Healthcare Workers in Kiambu County, Kenya

Coronavirus Disease 2019 (COVID-19) placed significant pressure on global health systems, necessitating rapid and widespread immunization, especially among healthcare workers (HCWs). Despite being prioritized in immunization programs, variations in vaccine uptake among HCWs have been reported across different settings. This study aimed to investigate the predictors of COVID-19 vaccine uptake among HCWs in Kiambu County, Kenya. An analytical cross-sectional study design was employed, involving 112 HCWs sampled using stratified random sampling from Level 2 to Level 5 healthcare facilities. Data were collected through a pre-tested and validated 18-item questionnaire and analyzed using SPSS version 29.0. Statistical methods included descriptive analysis, chi-square tests, logistic regression, and ANOVA. The overall COVID-19 vaccine uptake was 88.9%. Significant predictors of uptake included age (p = 0.048), cadre (p = 0.015), and facility level (p = 0.031). Knowledge of COVID-19 vaccines emerged as the strongest predictor, with HCWs demonstrating good-to-excellent knowledge being 14.97 times more likely to be vaccinated (p < 0.001). Confidence in vaccine safety and effectiveness was also significantly associated with uptake (p < 0.001). Uptake was highest in Level 5 hospitals and lowest in dispensaries. The study reveals high vaccine uptake among HCWs in Kiambu County, but disparities persist due to individual and systemic factors. Strengthening vaccine education, institutional support, and deploying mobile vaccine education units in lower-level facilities could help close these gaps, offering practical strategies for improving HCW vaccine coverage in Kenya and other low- and middle-income countries.

RETRACTED: Association of Body Mass Index (BMI) and Severity of COVID- 19: A Multicentric Study from Maharashtra, India

This article has been retracted on 30 August 2025. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2379-7835.ijn-25-5842) Objective The COVID-19 pandemic has led to the global research efforts to identify the risk factors which would lead to severe COVID-19 disease. This study aimed to investigate the relationship between body mass index (BMI) and severity of coronavirus disease 2019 (COVID-19). Methods A total of 2820 patients hospitalized with COVID-19 disease in nine Government Medical Colleges, COVID hospitals or COVID care centers of Maharashtra were included in the study. Interviews were conducted on the telephone and counselling was done. Results Among 2820, 2442 (86.60%) were asymptomatic or had a mild or moderate illness. More than half of the total COVID- 19 positive cases, 1591 (56.41%), were in the normal BMI range, and of these only 183 (11.50%) had severe COVID-19 disease. On the other hand, 647 (22.94%) patients were overweight and 106 (16.38%) had Severe COVID- 19 disease. Similarly, the patients who were obese, 363 (84.03%) were asymptomatic and 69 (15.97%) had severe COVID- 19 disease. Odds ratio for this association was found as 1.5, which indicates that patients who were obese (BMI ≥ 27.5) had one and half times increased odds of progression to severity as compared to patients having normal BMI. This association was found to be statistically significant (p- value < 0.05). Conclusion Our findings highlight the significant role of BMI in clinical progression of COVID-19 disease. Patients with underweight and obesity experienced more severe outcomes than those of normal weight when being hospitalized with COVID-19 disease.

COVID-19-Induced Changes in the Fibrin Network of Pulmonary and Renal Microthrombi

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection often causes coagulation disorders that affect highly vascularized organs, such as the lungs and kidneys. Objective The objective of this study was to report the histopathological findings of variations in the fibrin pattern of pulmonary and renal microthrombi in patients who died from SARS-CoV-2 infection. Methods Minimally invasive autopsies were performed on 40 patients to collect lung (n=40) and kidney (n=16) tissue samples. Histochemical and immunohistochemical staining techniques were used for histopathological analyses. Premortem laboratory data were obtained from the patients' electronic medical records. Results The lung tissue showed a patchy pattern, characterized by areas of both minimal and severe damage. The most significant histopathological finding was the detection of thrombi with fibrin structures organized into discrete star-shaped units, which were more frequently observed in areas with severe lung injury than in those with minimal lung injury (p = 0.012). Star-shaped fibrin structures were also observed in the renal glomerular capillaries. Immunohistochemical staining revealed the presence of platelets and the procoagulant proteins von Willebrand factor (VWF) and Factor VIII within the star-shaped fibrin thrombi. Patients with star-shaped fibrin thrombi had higher levels of the systemic inflammatory indicators C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR). Conclusion Our observations suggest that the inflammatory microenvironment resulting from SARS-CoV-2 infection may contribute to the formation of star-shaped fibrin units in the pulmonary and renal microthrombi.

A Systematic Review of Dengue Fever and Dengue-Associated Neurological Conditions Was Conducted in an Attempt to Better Understand This Disease

Dengue is a global arbovirus disease primarily carried by Aedes aegypti and Aedes albopictus mosquitoes. It has four serotypes (DENV1, DENV2, DENV3, and DENV4) and is classified into distinct genotypes. The epidemic is complicated by immunological interactions and viral lineage turnover. Neurological problems are commonly associated with DENV2 and DENV3, with DENV2 displaying the most severe symptoms. Direct viral invasion, host-mediated immune system reactions, or host-mediated metabolic alterations can all result in dengue-related neurological issues. The three dengue vaccinations and the significance of meta-analyses for genetic data will also be covered. Finally, establish a connection with the microRNAs associated with dengue fever, creating new opportunities for the creation of dengue treatment regimens involving microRNAs.

Cosmic Surgery: Development of a New Non-Invasive Technique in Modern Surgery.

Cosmic surgery is a non-invasive operation developed by applying modern astronomical discoveries to surgical science. Scientific cosmology is the study of the universe through physics and astronomy. Religious cosmology explains the universe based on religious scriptures. According to religious cosmology, the universe consists of hell, heaven, and earth. Earth is surrounded by hell, and hell is surrounded by heaven. Astronomers explored the universe and found billions of galaxies of stars all around the earth made of hellish fire. The location of the stars and hells in the universe and their characteristics are identical. Comparative study shows that all the stars in the visible galaxies of the universe are religious hells. The discovery of hells in the lower universe confirms the existence of heavens in the inaccessible upper universe that has been predicted in the Holy Scriptures. This astronomical discovery is not only a message to mankind but also a recombinant cosmic signal all over the world, which is generated for the exploration of the cosmos by prophets and astronomers. According to the supernatural theory of disease, supernatural virus infects the prefrontal cortex of the human brain and disrupts the normal spirit of executive functions including reasoning, planning, motivation, and problem solving that leads people to a delusional lifestyle and behavior and alters the dynamic equilibrium between man and environment, and causes all physical, mental, social, and spiritual disorders, national, international, and inter-religious conflicts and wars in the world. Cosmic surgery is a non-invasive operation applying above mentioned cosmic signal to the human brain to sterilize the whole world from the supernatural virus that can change our sick world into a healthier, happier, and prosperous world like a terrestrial paradise.

Impact of Family Planning and Religious Belief upon Family Growth in Addis Ababa, Ethiopia, 2022

Introduction Family and virus programs are currently important for union and about 7 million, and unfortunately (250 million) reproduce. Above the place, it closes; it's slow, slow, causing serious injuries and women during pregnancy. In addition to friends and couples who want health and quality and quality and quality and quality. Especially in a hurry, access to FPS is valid and accessible limited, or you have the opportunity to go home safe and healthy and health plan programs. The final change is very associated with its own interests in the world. The focus agreement in women of fecund women takes advantage of the opportunity to defend themselves between women's threats. In addition, women are classified with different methods. Objectives To assess the Impact of Family Planning and Religious Belief upon Family Growth in Addis Ababa, Ethiopia. METHODS Research style was a descriptive cross-sectional survey, which assessed the employment of semi permanent strategies and effects of contraception among ladies of fruitful age, through health facilities in Addis Ababa, Ethiopia. Data are entered in to applied math software package Epinfo v 3.7 and export into SPSS to code decrypt and analysis. Outcome is gift as a variety of table, graph and bivariat and multi chance variable regression are presented. Result The magnitude of current utilization of modern contraceptive was 59 % among women in Addis Ababa public health facilities. Age (AOR =0.14(95%CI(0.03-0.68)), Educational status (AOR=0.04(95%CI (0.02- 0.63)), number of children wanted (AOR=10.8(95%CI (4.02- 18.97)) and communication with partner about modern contraceptive use (AOR=3.17(95%CI (0.89-11.27)) were statically significant factors for utilization of modern contraceptive.

A Review on Monkey Pox: Role of One Health Approach Against Monkey Pox

The Ortho-poxvirus virus, which causes monkey pox, is a member of the Poxviridae genus. It was initially found in primates. In 1970, the Democratic Republic of the Congo reported the first instance of monkey pox. From there, it spread to a number of countries both inside and outside of Africa. There are two genetic varieties of monkey pox, which have been spread to people through respiratory droplets, and touch with objects contaminated by an affected person and consequently is often encountered in work situations. Among the countries with the worst effects are Nigeria and the Democratic Republic of the Congo. Non-human primates, rats, squirrel, and or mice are just a few of the creatures that can become infected by monkey pox. Although the origins of monkey pox infections are unknown, rodents from Africa and non-human primates like monkeys may contain the viruses and infect humans. Monkey pox is more likely to naturally infect rodents. Monkey pox has symptoms and lesions that are difficult to distinguish from smallpox in its clinical manifestations. Fever, chills, migraines, tiredness, tonia, swollen lymph nodes, back pain, and myalgia are some of the clinical symptoms of monkey-pox. A few examples of diagnostic tests include immune-fluorescent antibody assays, enzyme-linked immune-sorbent assays, and real-time polymerase chain reactions. A specialized vaccine that offers complete protection against by them on key-pox virus exists, yet there is no specific therapy for human monkey infection and interaction with the vaccinia virus. Smallpox vaccination can give cross-immunity with partial protection against infection and a reduction in symptom severity. Unfortunately, community health effects in the view of one health approach has not been addressed in vast. Therefore, the objectives of this review paper are to discuss the community health effects of monkey pox and to emphasize the role of one health approach against monkey pox.

Knowledge And Preventive Practice Towards Covid-19 Infection Among Pregnant Women In Public Hospitals Addis Ababa, Ethiopia, 2022

Background The novel coronavirus COVID-19 has created massive challenges to public health worldwide. Pregnant women are an immune-depressed status which makes pregnant women generally more vulnerable to COVID-19 infection and severe illness. The present preventive measure practices have gaps. Therefore, the current study aimed to present accurate and latest information regarding preventive measures for COVID-19 infection among pregnant women. Methods and materials Institution-based cross-sectional study design was conducted on 422 pregnant women in public hospitals in Addis Ababa using a pretested structured questionnaire. Face-to-face interview on pretested and structured questions was conducted to collect the data between January 12 and February 15, 2022. The collected data were entered into Epi data version 4.4.2.2 and exported to SPSS window version 25 for analysis. Descriptive statics and multivariable logistic regression were analyzed. Odds ratio with a 95% confidence interval and p-value ≤ 0.05 were declared statistical significance independent variables. Result A total of 418 pregnant women participated, and the response rate was 99.05%. About 417 (99.8%) pregnant women reported never hearing about COVID-19. Of those who heard about COVID-19, only 49% and 54.3% had good knowledge and had good practice towards COVID-19 infection respectively. Age (26-30yrs (AOR=0.46, 95%CI: 0.014,0.12), no education (AOR=0.23, 95%CI: 0.099-0.52), Primary school (AOR=0.199, 95%CI: 0.104-0.4) and Secondary school (AOR=0.282, 95%CI: 0.14-0.55), divorced (AOR=0.15, 95%CI: 0.065-0.34) and widowed (AOR=0.16, 95%CI: 0.024-1.03)) were factors that associated with knowledge towards COVID-19 infection. Age (30-35yrs (AOR=0.334, 95%: 0.115-0.97) and >36yrs (AOR=0.28, 95%CI: 0.11-0.69)), no education (AOR=0.06, 95%CI: 0.019-0.18), being a civil servant (AOR= 0.28, 95%CI: 0.122-0.66), divorced (AOR=0.042, 95%CI: 0.01-0.18), having >4 family size (AOR=0.334, 95%CI: 0.169-0.66), no previous complication of pregnancy outcomes (AOR=0.019, 95%CI: 0.01-0.061), chronic health problem (AOR=14.66, 95%CI: 0.457-39.4) and two ANC visit (AOR=5.704, 95%CI: 2.41-13.5) were factors that associated with the practice towards COVID-19. Conclusion In this study area, only half of pregnant women had good knowledge and good practice about covid-19 infection prevention measures.  

Pyrexia And Liver Injury After A Second SARS-CoV-2 Vaccination: Macrophage Activation Manifested In Liver

Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-Co V-2) has contributed to control of the coronavirus disease 2019 (COVID-19). On the other side, vaccination of SARS-CoV-2 could trigger autoimmune or inflammatory diseases. We present a 50-year-old female with well-controlled optic neuromyelitis with prednisolone (PSL) maintained at a dose of 2.5 mg/day. She ran a fever and liver injury was indicated 5 weeks after a second COVID-19 vaccination (BNT162b2 mRNA/Pfizer ). Liver biopsy showed accumulation of macrophages around the central veins, identified using anti-CD68 antibodies. As the treatment, cyclosporine A improved liver injury. COVID- 19 vaccination may have triggered liver inflammation due to cytokine storm via macrophage activation in the liver.

A General Approach to Modeling Covid-19

The present work shows that it is possible to analytically solve a general model to explain the transmission dynamics of SARS-CoV-2. First, the within-host model is described, and later a between-host model, where the coupling between them is the viral load of SARS-CoV-2. The within-host model describes the equations involved in the life cycle of SARS-CoV-2, and also the immune response; while that the between-Host model analyzes the dynamics of virus spread from the original source of contagion associated with bats, subsequently transmitted to a host, and then reaching the reservoir (Huanan Seafood Wholesale Market in Wuhan ), until finally infecting the human population.

Research Gaps In Contaminants Of Emerging Concern (CECs): Routes To The Standardization Of Chemical Test Methods By GC/LC-Mass Spectrometry: A Review

A literature review was undertaken with a focus on 1) identifying the research gaps regarding CECs, 2) identifying the most common ones, and 3) identifying the typical analytical methods/technologies employed, for their analysis. A total of 214 papers were noted, with a total of 21 review articles (9.8%). Of this total, a surprisingly high number were from South Africa alone: 117 (54.7%), of which 44 (20.6%) reports were associated with South Africa’s Water Research Commission (WRC). The top three CECs research gaps were (decreasing rank: Number of “gaps”, %): 1) Toxicity/Risk/Impact (260, 21.5%), 2) Analysis/Tests/Methods (118, 9.8%) and 2) Future research/studies (118, 9.8%), and 3) Monitoring (89, 7.4%). The common classes of CECs that were reported on, were : (i) Chemical: pharmaceuticals, personal care products, steroids, chlorinated and brominated contaminants, PAHs, PCBs, phthalates, alkyl phenols, herbicides, organochlorine pesticides, engineered nanomaterials and (ii) “Microbiological”: antibiotic resistance genes, human enteric bacteria and viruses, microbial pathogens (e.g., E Coli, rotavirus, Crypto, etc.), infectious biological water contaminants (e.g., E Coli isolates), cyanobacterial blooms (Microcystis). Common test methods used for analysis of the chemical contaminants were found to be chromatography (gas, liquid)-mass spectrometry; for the microbial contaminants, they were culture-based methods, ELISA, fluorescence microscopy, qPCR, RT-qPCR, gel electrophoresis, Raman spectroscopy, and also chromatography (largely liquid)-mass spectrometry, were also used. Some proposals were additionally made to address the very common, significant research gaps noted in CECs research, especially the standardization of analytical chemical test methods, based on chromatography-mass spectrometry, for quantification.

Time Series Analysis and Prediction of COVID-19 pandemic using Dynamic Harmonic Regression Models

Rapidly spreading Covid-19 virus and its variants, especially in metropoli- tan areas around the world, became a major health public concern. The tendency of Covid-19 pandemic and statistical modelling represent an urgent challenge in the United States for which there are few solutions. In this paper, we demonstrate com- bining Fourier terms for capturing seasonality with ARIMA errors and other dynamics in the data. Therefore, we have analyzed 156 weeks COVID-19 dataset on national level using Dynamic Harmonic Regression model, including simulation analysis and ac- curacy improvement from 2020 to 2023. Most importantly, we provide a new advanced pathways which may serve as targets for developing new solutions and approaches.

Seasonal ARIMA model for Covid-19 pandemic Prediction in the United States

The COVID-19 pandemic has had a profound impact on global health and economies. The pandemic continues to spread and accurate forecasting of its spread is essential for the effective management of healthcare systems and the development of effective policies. The development of forecasting models for COVID-19 has become increasingly important as the pandemic continues to evolve. In this paper, we will summarize the Covid-19 pandemic in the United States state by state. And then, we utilize the temporal data of coronavirus spread from January 18, 2020 to January 29, 2023. Finally, we model the evolution of the COVID-19 outbreak and perform prediction using ARIMA and time series forecasting models on some selected states.

Review of Human, Social and intellectual capital in the Covid-19 era

The health and economic crisis caused by the SARS CoV-2 coronavirus and the Covid-19 disease has accelerated the emergence of an informational economy focused on the use of electronic networks. The impact of this scenario on education led to the transition from the traditional classroom to the electronic whiteboard. The objective of the present work was to analyze the relationships between human, social and intellectual capital. A model was established in which the prevalence of human capital formation indicated by data processing in the virtual classroom and self-management of knowledge is appreciated.

Willingness to take COVID-19 Vaccination among People Living with HIV/AIDS on Anti-Retroviral Therapy and Associated Factors in Woldia Comprehensive Specialized Hospital, Woldia, Ethiopia

Background HIV causes immunosuppression, which reduces the body's immunity to diseases like COVID-19 by decreasing CD4 cells. The goal of this study is to determine whether persons living with HIV/AIDS (PLWHA) who are using anti-retroviral therapy (ART) are willing to accept the Coronavirus illness 2019 vaccination and the factors that influence their decision. Method From February 15 to March 15, 2022, 332 PLWHA on ART participated in this facility-based cross-sectional study. The correlation of outcome variables with predictors was investigated using binary and multivariable logistic regression. Result Of the 332 study participants, 110 (33.1 %) and 118 (35.5 %) had poor knowledge and a negative attitude toward the COVID-19 vaccination, respectively. Approximately 31 (9.3%) of study participants believe ART medications can also prevent COVID-19 infection. The willingness to receive the COVID-19 vaccine was 66.3 % with a 95 % confidence interval (60.9, 71.5). Knowledge, attitude, educational status, marital status, residency, duration, and monthly income were all significant predictors of willingness to receive COVID-19 vaccination. Conclusion Increased sensitization regarding the necessity of vaccines and the negative consequences of diseases, particularly among PLWHA, should be emphasized in the preparation of the COVID-19 immunization campaign involving prominent individuals such as health professionals and religious leaders.

Pandemic Impact on Population Structure

The victims of the first wave of the pandemic caused by the coronavirus Covid-19 were tens of millions of people in the population inhabiting the Earth. A previously unknown strain of Covid 19, which has a specific affinity for lung tissue and high contagiousness, has demonstrated a global danger to the life of the population of the entire planet. The pathogenicity of the virus is due to a three-segment structure, in which the RNA-containing segment, which is a pathogenicity factor responsible for specific lesions, most likely has an enzymatic nature.

Predictors of Adherence to Pre-Exposure Prophylaxis among Female Sex Workers in South-Western Nigeria

Introduction Pre-exposure prophylaxis (PrEP) is an element of the biomedical interventions of Human Immunodeficiency virus (HIV) prevention. The level of protection is strongly correlated to PrEP drug adherence. In Nigeria, the prevalence of HIV among female sex workers (FSW) is 15.5%. The 2020 integrated biological and behavioral surveillance survey did not report on PrEP adherence among FSW. This study therefore assessed the level of adherence to PrEP and its predictors among FSW in South-Western Nigeria. Methodology This cross-sectional analytical study was conducted in 2021. Study population were brothel-based FSW at Gambari Ogbomoso and Lagos, Nigeria. A total of 156 FSW participated in the study. Data was collected using interviewer-administered semi-structured questionnaire and analyzed using IBM SPSS Version 25. Results One hundred and forty-nine properly completed questionnaires were analyzed. Ninety-nine respondents (66.4%) have been working for more than 5years as a FSW and 65(43.6%) had initiation of sex work before 18 years of age. Respondents’ sexual behavior showed that 55 (36.9%) of total respondents had consistent use of condom. One hundred and thirty-four respondents (89.9%) had good knowledge of PrEP, 97 (65.1%) had good attitude towards PrEP while 111 (74.5%) had good perception of risk of HIV infection. One hundred and thirty-two (88.6%) reported to be taking PrEP and 119 (79.9%) had good adherence to PrEP. Predictors of adherence to PrEP were educational status, age of commencement of sex work and monthly income. It was found that educated sex workers were 2.67 times more likely to adhere to PrEP (OR=2.67, 95% CI=1.280-5.591, p=0.019). Those who commenced sex work after clocking 18 years of age were 75% times less likely to adhere to PrEP (OR=0.251, 95% CI=0.106-0.597, p=0.001) while those with average monthly income more than #10,000 were 1.65 times more likely to adhere to PrEP (OR=1.65, 95% CI=0.674-4.042, p=0.0275. Discussion and Recommendation The level of adherence to PrEP is considerably high and underscores a positive effect of the efforts of the Government of Nigeria in controlling HIV as a threat by 2030. Further studies would be useful to understand the behavioral factors associated with low adherence to PrEP among FSW who have spent more than 5 years in sex work.

HIV and Homosexuality: In the Light of Therapeutic Interventions

In this article the author reviews research on high risk factor of Human Immunodeficiency Virus in homosexuals and how lack of awareness & unprotected anal sex contribute substantially to new infections among this population. current HIV prevention efforts by providing insight into the patterns of Indian MSM behavior and sexual partnerships, and the specific cultural, social inequality, the gaps and lack of knowledge and psychological context in which HIV risk is occurring. And the need to develop effective awareness programs for well-functioning prevention of HIV and considerable understanding of the logistical and socio-cultural barriers MSM experience while accessing HIV prevention services. And in last will put light on therapeutic interventions for Human Immunodeficiency Virus, behavioral interventions that are socially and culturally appropriate for the population or community being prioritized and addressing multilevel psychosocial factors, including skills building and strategies to foster self-acceptance and increased social support for MSM. At the same time, prevention messages need to be designed and adapted to the knowledge level and culture of people.

Analysis of Risk of Death due to COVID-19 in Cameroon

Background Cameroon is battling against the novel coronavirus (COVID-19) pandemic. Although several control measures have been implemented, the epidemic continues to progress. This paper analyses the evolution of the pandemic in Cameroon and attempts to provide insight on the evolution of COVID-19 within the country’s population. Methods A susceptible-infected-recovered-dead (SIRD)-like model coupled with a discrete time-dependent Markov chain was applied to predict COVID-19 distribution and assess the risk of death. Two main assumptions were examined in a 10-state and 3-state Markov chain: i) a recovered person can get infected again; ii) the person will remain recovered. The COVID-19 data collected in Cameroon during the period of March 6 to July 30, 2020 were used in the analysis. Results COVID-19 epidemic showed several peaks. The reproductive number was 3.08 between May 18 and May 31; 2.75 between June 1 and June 25, and 2.84 between June 16 and June 24. The number of infected individuals ranged from 17632 to 26424 (June 1 to June 15), and 28100 to 36628 (June 16 to June 24). The month of January 2021 was estimated as the last epidemic peak. Under the assumption that a recovered person will get infected again with probability 0.15, 50000 iterations of the Markov chain (10 and 3- state) demonstrated that the death state was the most probable state. The estimated lethality rate was 0.44, 95%CI=0.10%-0.79%. Mean lethality rate assuming ii) was 0.10. Computation of transition probabilities from reported data revealed a significant increase in the number of active cases throughout July and August, 2020, with a mean lethality rate of 3% by September 2020. Conclusion Multiple approaches to data analysis is a fundamental step for managing and controlling COVID-19 in Cameroon. The rate of transmission of COVID-19 is growing fast because of insufficient implementation of public health measures. While the epidemic is spreading, assessment of major factors that contribute to COVID-19-associated mortality may provide the country’s public health system with strategies to reduce the burden of the disease. The model outputs present the threatening nature of the disease and its consequences. Considering the model outputs and taking concrete actions may enhance the implementation of current public health intervention strategies in Cameroon. Strict application of preventive measures, such as wearing masks and social distancing, could be reinforced before and after the opening of learning institutions (schools and universities) in the 2020/2021 calendar year and next.

Dolutegravir: Pharmacokinetics and Pregnancy Profile

Dolutegravir suppresses this integration enzyme, so human immune virus can’t create every greater copies of itself, thus ‘’integrase inhibitor.’’ Dolutegravir is hastily absorbed pursuing oral administration. The median maximum plasma concentration is reached 1.5–2.5 hours after oral uptake with a mean half-life of 12–15 hours, rendering feasible for once-daily dosing without the need for pharmacological boosting. The terminal half-life is about 14 hours. The apparent oral clearance is about 1 liter/hour. Fifty three percent of the total oral dose of dolutegravir is excreted unchanged in the feces, thirty two percent through urine as glucuronide (eighteen percent) or alkylated product (three point five percent), and other organic conjugated products sequencing from phase II liver metabolisms. Dolutegravir’s categorized as pregnancy category B (no confirmation of pitfall in humans) means either animal-reproduction inquests have not substantiated a fetal peril but there are no restrained inquests in pregnant women or animal-reproduction inquests have reveal an adverse effect (distinctive than a de-escalate in fertility) that was not inveterate in restrained inquests in women in the first trimester (and there is no confirmation of a pitfall in later trimesters) or there is survey in animal that revealed the medication is safe in pregnant animal, but there is no fetal pitfall confirmation in pregnant women.Antiviral Pregnancy Registry (APR) revealed that as of January 2017, pregnancy outcomes and birth defects were analyzed from 142 pregnancies with reported exposure to DTG during pregnancy. There were 128 live births reported (3 terminations, 11 miscarriages, no stillbirths). Only 4 (3.0%) reported birth defects, which is similar to the expected rate of birth defects in the general population. European Pregnancy and Paediatric HIV Cohort Collaboration (EPPIC) displayed that as of July 2017, 101 pregnancies with exposure to DTG had been identified with 84 birth outcomes. Rates of preterm delivery and “small for gestational age” were identical to outcomes reported from women on alternative regimens (standard of care in the United Kingdom of Great Britain and Northern Ireland).

Expression of Concern: Potential Risks and Unknown Effects of mRNA Vaccines on Population Health (6th Rev). Damages Are Being Materialized

Several mRNA vaccines are used on the population in the U.S. I started predicting the dangers of mRNA vaccines before March 2021 and update my findings periodically. My prior model study enabled me to identify many flaws in clinical trials, side-effect evaluation methods and mechanism studies, and I also considered consistent failure in predicting drug side effects in the past and systematic failure of FDA in keeping out dangerous drugs from market. I found that the risks of vaccination cannot be determined by experiments alone and must be determined by using a combination of methods. By studying mRNA expression dynamics and kinetics, I predict that vaccination with mRNA vaccines may increase cancer risks, multiple organ failure risks, earlier death risks, genome alteration speeds by one or more mechanisms, alter the normal selection process for viral evolution resulting in more virulent viruses, and aggravate chronic diseases or cause healed diseases to relapse. Two root problems are practical inability to control expression sites and severe adverse reactions from repeated vaccination. Based on mRNA bio-distribution, the mRNA mainly strikes the liver and other vital organs, and poses grave dangers to persons whose vascular functional reserves are relatively small, or whose vascular systems are temporarily burdened by other causes such as viral infections or life activities. If an mRNA vaccine is administered on a pregnant woman by second or booster shots, spike protein synthesis in fetus brain disrupts the highly regulated protein synthesis processes, resulting in potential brain damages. In less than a year, most of my early predicted damages are being materialized or are on the track to hit the population. In this update, I present a benefits-and-risks map to show how the number of deaths caused by mRNA vaccines is grossly underestimated and why claimed benefits like 95% effectiveness rate and 90% death rate reduction are meaningless and misleading.

What Could Represent the Mantissa of the Registered Covid-19 Cases?

In this work we present how it is possible to visualize the different coronavirus outbreaks from the calculation of the mantissa from the daily record of cases by Covid-19.This curve can also indicate the speed of propagation of the disease from the calculated infection rate. These conclusions are derived from the respective calculations in four different countries: Australia, Brazil, Italy, and Venezuela.

Post-Covid-19 Acute Disseminated Encephalomyelitis (ADEM) in a 27-year-old girl: Case Report

Acute disseminated encephalomyelitis (ADEM) is a monophasic, multifocal, demyelinating, autoimmune disease that affects the central nervous system (CNS). It usually occurs after a systemic infection, usually viral, including certain coronavirus infections. A 27-year-old girl presented with complaints of left interscapular pain, paresthesias and weakness in the ipsilateral upper limb. These symptoms followed paresthesias on the fingertips of her right hand the day before her admission. she was treated two weeks earlier for pneumonia with COVID-19. Her clinical pattern resulted in a moderate weakness of the left limbs associated with tactil and algic hypoesthesia in the lower left limb ascending until the C4 level in the left side. Magnetic resonance imaging (MRI) of the brain and spinal cord showed diffuse spontaneous hypersignals on fluid-attenuated inversion recovery (FLAIR) images at the cerebral level and on T2-weighted images at the spinal level. These imaging lesions coupled with the medical history of a recent COVID-19 infection led to the diagnosis of acute disseminated encephalomyelitis (ADEM) post covid-19. The clinical condition improved rapidly with intravenous (IV) corticosteroid therapy and IV immunoglobulin combined with physiotherapy. ADEM is a demyelinating autoimmune disease which is increasingly reported during this current corona virus pandemic.

New Approach in Treatment of Cancer & Viral Infection by Apis Mellifera L Venom Extracts (Honeybees Venom)

Cancer cells need strong drug to be eliminated. Cancer lesions cure could achieve by topical application of crude bee venom. Bee venom medication used to prevent malignancies in groups most at risk (predisposing factors). Bee venom crosses the blood brain barriers because its components are very small. However, Bee venom contraindicated administered by intravenous injection because it’s hemolytic substance, mellitin which is powerful anticoagulant. However, the cationic peptides mellitin govern the mode of action of bee venom as anticancer and antiviral in vivo; 1 there is a negative charge on cancer cells, viral infected cells, diseased cells, and generally any cells that contain toxins or damage, and viruses are carrying negative charge even when it is outside the living body. 2Bee venom component (melittin) carries a positive charge, it destruct negatively charged cancer cells. 3 The role that the herpes virus is likely to play in increasing the severity of cancerous diseases, worsen the conditions: herpes viruses are opportunistic viruses that strike the body whose immunity is weakened for any reason. Therefore, the role of herpes virus must be neutralized when you planning to treat a cancer patient. Fortunately, bee venom is a powerful antiviral, and thus we hit three birds with one stone, that is, we kill cancer cells, kill opportunistic viruses, and improve tissue immunity to participate in the fight against cancer and get rid of toxic exudates more efficiently.

Cytokine Profiling in COVID-19 Patients in a Tertiary Hospital in Saudi Arabia; the Pre-Storm Phase

Background As COVID-19 immunomodulation has been a part of interest for studies, it has been found that severe coronavirus disease 2019 (COVID-19) is associated with hyper-inflammatory response and increased levels of interleukin-6 (IL-6) and interleukin-10 (IL-10). This can progress to cytokine storm syndrome and eventually development of acute respiratory distress syndrome (ARDS). Interleukin-1 receptor antagonist (IL-1RA) is a protein that is a member of the interleukin 1 cytokine family. Monocyte chemoattractant protein 1 (MCP1) is a small cytokine that belongs to the CC chemokine family. Interferon gamma-induced protein 10 (IP-10) is a protein secreted by several cell types in response to Interferon-Gamma (IFN-γ). All of these have roles in the immune response and eventually development of a cytokine storm. Methods Serum levels of IL-1RA, MCP-1 and IP-10 were measured in a cohort of 21 patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on admission to a tertiary care hospital in Riyadh, Saudi Arabia, as well as in an approximately age-sex matched group of 4 uninfected controls. The study population was classified into severe, moderate, mild and controls. Results Serum levels of IL-1RA, MCP-1 and IP-10 were found to be elevated before the clinical deterioration. Conclusion These cytokines may play a role in early detection of disease severity especially in the pre-storm phase. Medications that target cytokines may prevent the development of an overt cytokine storm.

Validity of PIRO Score as an Assessment Tool for Mortality Risk of COVID-19 Pneumonia among Patients Admitted to World Citi Medical Center from March to August 2020. A Retrospective Observational Cohort Study

Introduction In December 2019, cases of serious illness causing pneumonia and death were first reported in Wuhan, China.2 The clinical features of Corona Virus Disease-19 (COVID-19) are ranging from asymptomatic to multi organ dysfunction. The disease can progress to pneumonia, respiratory failure and death.4 Thus, a tool is needed that can predict the severity and in-hospital mortality risk of a patient with COVID-19 Pneumonia. The PIRO (predisposition, insult, response, and organ dysfunction) scoring was developed for use in the emergency department to risk stratify sepsis cases.15 Eventually it was adapted in pneumonia cases to predict its severity. Objective To validate PIRO score as an assessment tool for COVID-19 mortality risk among patients with confirmed COVID-19 RT-PCR test among patients aged 19 and above admitted in World Citi Medical Center from March 2020 to August 2020 Methods This study included 93 patients aged 19 and above admitted in World Citi Medical Center with a primary diagnosis of COVID-19 Confirmed with pneumonia between March 2020 to August 2020. The patients’ charts were retrieved from the hospital medical records and case notes were reviewed. A severity assessment score was developed based on PIRO score (Predisposition comorbidities and age; Insult multilobar opacities and viremia; Response shock and hypoxemia; Organ Dysfunciton) were extracted. The patients were stratified in four levels of risk: a)Low,0-2 points; b)Mild,3 points; c)High,4 points; d)Very High,5-8 points. The PIRO score and the clinical outcome were compared. The discriminative ability of PIRO score to predict mortality risk was evaluated under receiver operating characteristic curve (AUC). Results The PIRO score had an excellent predictive ability for in-hospital mortality (AUC0.9197). Analysis of variance showed that higher levels of PIRO scores were significantly associated with higher mortality (p<0.001). Patients with Mild PIRO risk category were 98.65% less likely to expire (p<0.001, 95%CI 0.0015) and High PIRO risk category were 94.47% less likely to expire (p<0.001, 95%CI 0.0124), both compared to patients with Very high PIRO risk category. Finally, Very High PIRO risk category were more than 44 times likely to expire compared to patients with Low, Mild and High PIRO risk category (p<0.001, 95%CI 11.738). Conclusions The PIRO score is a valid risk model that can be used to predict in-hospital mortality, that can help clinicians provide timely and accurate assessment, and hence appropriate management to patients with COVID-19 Pneumonia.

Impact of COVID-19 on Cognitive and Way to Resolve

Cognitive abilities are of immense importance for the normal life sustenance of a human being. As cognitive impairment ensues, the living caliber declines. Among multiple factors, the current epidemic coronavirus diseases 2019 (COVID-19) has been implicated in worsening cognitive performance of the COVID-19 sufferers. Present article pinpoints the etiology and patho physiology as well as recommendations to overcome the COVID-19 led cognitive decline.

Position Paper: Overview of Workplace Bullying in Higher Educational Organizations

Coronavirus disease (COVID-19) outbreak has severely affected the whole world. It has overshadowed all the developmental activities across different countries. The COVID-19 pandemic has negatively affected global economy and has threatened health security of people worldwide. This pandemic have affected environment dynamically. Decrease in economic activities, travelling, transport and traffic restrictions all over the world have led to decreased emissions of greenhouse gases and drop in air and water pollution observed universally. Also more than 40 % of downfall is observed in NO2 concentration in Asia and Europe as compared to 2019. Reduced pollution had a good effect on freshwater aquatic life. The reduction in worldwide aircraft flight directly impact on forecast and decreases 65% of weather prediction. Snow fall was observed even in a summer in India. This pandemic has had a long-term impact, affecting all aspects of human life and halting all developmental processes. Combating the COVID-19 pandemic is currently at the top of the global agenda. Quarantine measures opted for safety of the public have positively affected the environment. Although it has downturned the economic growth drastically, it has also contributed in lowering the pollution. If there is a silver lining to this horrible situation, it may be that it has given us a whiff of the air we will breathe in a low-carbon future.

Six Fractal Codes of Biological Life Unifying ATOMS, WAVES and INFORMATION: Perspectives in Exobiology, Cancers Basic Research and Artificial Intelligence Biomimetism Decisions Making

In this theoretical discovery of a law of Life, there is MATHEMATICS (Geometry, Bits and Numbers) that UNIFY 3 universes as complementary as ATOMIC MASS, WAVES, and INFORMATION (DNA, RNA and Amino Acids). The discovery of a simple numerical formula for the projection of all the atomic mass of life-sustaining CONHSP bioatoms leads to the emergence of a set of Nested CODES unifying all the biological, genetic and genomic components by unifying them from bioatoms up to 'to whole genomes. In particular, we demonstrate the existence of a digital meta-code common to the three languages ​​of biology that are RNA, DNA and amino acid sequences. Through this meta-code, genomic and proteomic images appear almost analogous and correlated. The analysis of the textures of these images then reveals a binary code as well as an undulatory code whose analysis on the human genome makes it possible to predict the alternating bands constituting the cariotypes of the chromosomes. The application of these codes to perspectives in astrobiology, cancer, and specifically in INFORMATION THEORY with the emergence of binary codes and regions of local stability (voting process), whose fractal nature we demonstrate, is illustrated. PREFACE by Professor Luc Montagnier Addendum by Robert Friedman M.D After the discovery of the DNA double helix structure allowing both the stable storage of genetic information and its transfer through messenger RNA to protein synthesis organelles themselves structured by RNA most abundant in cells, the ribosomal. This wonder of nature exists in ALL living beings from the virus to humans and is based on two codes, the linear sequence of nucleotides and that derived from codons where three nucleotides allow with a certain flexibility - synonymous codons - the choice in the twenty amino acids. But we are missing a third CODE the one governing at multicellular beings from the rotifer to human, the stabilized modulation of gene expression in a nutshell the differentiation of cells from the single cell of the fertilized egg. It is logical to think that this program which begins as soon as fertilization is written in the DNA. We are also prone to associate it with non-coding DNA sequences although they control gene expression. I introduce here the notion developed by Jean-Claude Pérez of mathematical harmony, a higher order present in all living beings and whose existence it finds in genomes, including those of viruses. Thus the natural evolution of variants of the genome of coronavirus Covid 19 tends towards increasingly long Fibonacci series. It remains to determine the Who, the How and the Why of such developments. I will bet with my mathematician colleague that waves and fractals play a role. Luc Montagnier ADDENDUM Jean-claude has given scientists a strong new direction for research. He has identified a unified field of science guided by the Golden Ratio and Fibonacci Sequence. By identifying an overall guiding principle that makes possible fractal-like nesting at all levels of biological manifestation, future researchers can begin with the "whole" instead of the "parts". If we know that complex systems are organized at varying levels by the Golden Ratio and Fibonacci Sequence, we can look for those universal patterns first and then fill in the gaps with small details to complete the picture. It's like having an overall view of a crossword puzzle before beginning to assemble the individual pieces. Without an overarching vision and guiding principle, completing the puzzle is infinitely more difficult. Once scientists and researchers realize and begin using this "SECRET IN HIDDEN IN PLAIN SIGHT," their discoveries will be orders of magnitude more fruitful.  Robert Friedman M.D

RETRACTED: Profile of Children with Covid 19 Infection in our Set Up

This article has been retracted on July 20, 2022. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2692-1537.ijcv-25-5866) In December 2019, a novel coronavirus, now named as SARS-CoV-2, caused a series of acute atypical respiratory diseases in Wuhan, Hubei Province, China. The disease caused by this virus was termed COVID-19. The virus is transmittable between humans and has caused pandemic worldwide. The number of death tolls continues to rise and a large number of countries have been forced to do social distancing and lockdown. In humans, COVIDs mostly cause respiratory and gastrointestinal symptoms. Clinical manifestations range from a common cold to more severe disease such as bronchitis, pneumonia, severe acute respiratory distress syndrome, multi-organ failure and even death. Preliminary evidence suggests children are just as likely as adults to become infected with SARS-CoV-2 but are less likely to be symptomatic or develop severe symptoms. in our study , we consider the symptomatology , complications and mortality patterns of this disease in children.

Covid-19, Stigma & Law of the Leper

COVID-19 also known as Corona Virus is a new strain of Chronic Obstructive Pulmonary disease. While its virology is yet to be properly understood, its impact by way of human deaths is well registered. Stigma of infected persons is least mentioned as a ‘sub-strain’ that can push people into social isolation and exclusion (like in the book of Leviticus 13) leading to COVID-19 Related Depression (C-19RD). Using inter-disciplinary approach, this paper seeks to understand how this can happen in a COVID-stricken world.

Nutritional Status of Inmates in the Central Prison of Mbuji-Mayi, Democratic Republic of Congo

Background The nutritional situation in prisons of developing countries and the health status of inmates remain a major human rights concern. The objective of the study was to assess the nutritional status of inmates jailed in a prison of the Democratic Republic of Congo (DRC). Methods This cross-sectional study was conducted over a 4-month period in the Central Prison of Mbuji-Mayi, DRC. Three hundred inmates were selected according to the Malnutrition Universal Screening Tool (MUST). Severe malnutrition was defined according to Buzby index and Nutritional Risk Index (NRI). Data were analyzed by Stata™ (version12.0). Results The inmates were aged between 18 and 70 years and primarily males (88.7%). Of them, 24% were suffering from severe malnutrition and 62% of moderate malnutrition as based on the NRI. At the time of study, 88% of inmates were incarcerated for more than 6 months. Multivariate logistic regression analysis showed that factors independently associated with severe malnutrition were incarceration of more than 6 months (OR=5.1; 95% CI (1.5-17.4)), origin of food (prison vs. family or NGO) (OR=4.7; 95% CI (1.6-13.8)) presence of tuberculosis, human immunodeficiency virus and/or intestinal infections (OR=2.6; 95% CI (1.4-4.7)). Conclusions The nutritional situation in the Central Prison of Mbuji-Mayi is precarious. There is urgent need to supply enough nutrient-rich food to improve health of inmates.

Liver Disease: A Retrospective Hospital Based Study in Addis Ababa-Ethiopia

Background Liver disease has caused significant morbidity and mortality worldwide. Its epidemiologic and clinical pattern, however, is not well characterized in sub-Saharan countries. Objective This study aimed to describe demographic, clinical characteristics, and patterns of liver disease in a community hospital in Addis Ababa, Ethiopia. Method A retrospective hospital-based study was conducted on patients with liver disease admitted at Ras Desta Damtew memorial hospital, in Addis Ababa-Ethiopia, from February 2015 to April 2020. Result Of the total 212 patients majority, 78.8% were male, 49.1% of patients were in the age range of 31-50 with a median age of 42. The most common initial clinical presentation was ascites (87.7 %), and more than half of patients (56.6%) had a history of alcohol misuse documented on their medical charts. Chronic liver disease (cirrhosis) was found in 177 (83.5%), and Hepatocellular Cancer accounted for 7.5% of the patients. Alcohol misuse caused 45% of chronic Liver Disease, followed by Hepatitis B virus infection. Conclusion Chronic liver disease is the most common form of liver disease, and the most affected were middle-aged men. The common cause of chronic liver disease was alcohol followed by hepatitis B virus infection.

Use of the Remaining Sample from the Panbio COVID-19 Antigen Rapid Test Device for the Molecular Screening of the SARS-CoV-2 Variant of Concern B.1.1.7

Objective Real-time surveillance of SARS-CoV-2 variants of concern (VOC) is of essential public health importance. Rapid Antigen Detection Tests (RAgDT) have become first-line COVID-19 diagnostic methods in many regions, but this strategy can hamper the surveillance of the virus variants due to their decentralized performance. The aim of this study was to assess the usefulness of the remaining sample of a widely used RAgDT (Panbio) for the surveillance of the B.1.1.7 VOC using molecular methods. Methods Symptomatic individuals and asymptomatic close contacts of confirmed cases were routinely screened for SARS-CoV-2 infection using the RAgDT in Primary Health Care Centers. After performing the test, the extraction tubes containing the remaining biological material of RAgDT-positive cases were sent to the clinical microbiology laboratory where RT-PCRs detecting key mutations of the VOC were conducted. Results A valid result was obtained in 1770/1812 (97.7%) RAgDT-positive cases. Variant B.1.1.7 was detected in 34.7% of the patients, increasing from 0% to 87.7% between the weeks beginning January 4 and March 15, 2021. Conclusion The sample remaining after performing the Panbio RAgDT allowed to monitor the emergence and circulation of the B.1.1.7, greatly improving the population screened for the molecular study of SARS-CoV-2 variants.  

Impact of COVID-19 on Supply Chains in Zimbabwe

Zimbabwe like many other sub-Saharan African states has been struggling to provide a quality health service delivery system. Nations with rampant corruption and ineffective bureaucracy made worse, the response towards the fight against COVID-19, Coronavirus Disease 2019. Despite the Zimbabwean government setting out protocols with international agencies such as WHO, World Health Organization to mount an effective response against COVID-19, the health system has been overstretched with lack of personal protective equipment, shortage of drugs and essential equipment and wanton corruption practices coupled with shortage of staff. Timely delivery of orders is still a challenge due to strict bureaucratic measures when transporting goods and the existing competition between countries. Manufacturers and donors are shifting their focus to their countries leaving the Zimbabwean health service underfunded and under-resourced. However, among the challenges experienced the country has been given a chance to revisit its priorities and strategize how best the government and organizations can move essential medical goods, utilize current trade agreements such as ACFTA, African Continental Free Trade Area and local drug manufacturers to produce essential medicines. Launching an efficient mechanism to end corrupt practices in procurement and supply as well as improve interagency cooperation and communication may help improve efforts to end COVID-19 in Zimbabwe.  

Risk Reduction Intervention Services for In-school Adolescents in the rural Areas of Abia State of Nigeria

Introduction Risk reduction intervention is meant to provide enhanced and desirable interventions for HIV prevention among adolescents especially the in-school. Adolescents have been identified as the most vulnerable groups that can easily acquire human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs). Therefore, adolescents are the appropriate target for HIV prevention efforts. Most interventions for adolescents focus on providing AIDS-related education with the assumption that improving knowledge would enable adolescents to protect themselves from sexually transmitted infections. Numerous studies have shown that using class-room education alone is insufficient in reducing adolescents’ risky sexual behaviours. Therefore, this study used role-plays and peer facilitation for the study. Materials and Method The study used role-play and peer facilitation for the intervention strategy. The theme of the role-play was ‘My Future is My Choice’ (MFMC) intervention which was aimed to reduce HIV risk behaviours among sexually inexperienced adolescents. The role-play was carried out by 4 peer leaders who were trained in the theoretical framework of role-plays and peer facilitation by a consultant. With mastery and experience they carried out the role play in a regular classroom section for over 3 class periods, co-facilitated with the assistance of a volunteer teacher. A unique feature of this intervention was the dual focus on strategies that influenced both individual risk factors (i.e., attitudes, behavioural skills) and social environments (e.g., peer resources). A school was chosen by simple random sampling for the intervention. In the school chosen, a total sample of 65 students in senior secondary classes 2&3 ( SS2&3) were included in the study. These were the students considered to be sexually active who can respond to the questions in the questionnaire. Self-administered pre-and post-questionnaire were completed by the students. The results were analysed using frequency tables, descriptive and inferential statistics. Results The students studied were between the ages of 13-18 years. There was evidence that the role play ‘My Future is My Choice’ (MFMC) intervention created positive effects on reduction of HIV risk behaviours among the sexually inexperienced participants aged 13–18. Perceptions on methods of preventing risk reduction behaviours were also positively impacted by the intervention as 12(18.5%) and 34(52.3 %) of the respondents realized after post- intervention that having sex with someone outside marriage and being transfused with infected blood respectively Will constitute risk to HIV infection. Conclusion The role play which used the theme ‘My Future is My Choice’ (MFMC) intervention provided safer choices for reducing one or more measures of sexual risk behaviours among the sexual inexperienced respondents. It created the opportunity for the students to recognize that engaging in unprotected sex constitutes high risk for HIV, other sexually transmitted infections and pregnancy.

Overview of HIV Prevention among In-school Adolescents in the Rural Areas of Abia State of Nigeria

Introduction HIV prevention services to in-school adolescents need good planning and management. HIV risk reduction interventions are geared toward measuring sexual risk behaviour outcomes of adolescents that predispose them to HIV infection. The sexual behaviour of adolescents, especially in-school adolescents should be assessed in the process. Adolescents have been identified as the most vulnerable group for acquiring human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs) and as such, measures should be taken to prevent them from infection. One important reason for higher HIV prevalence among adolescents, especially girls, is the frequent practice of age-discrepant partnering, where older men, who are more likely to be infected with HIV, form sexual partners with younger girls. The objective of this study is to assess the knowledge and sexual behaviour of in-school adolescents in the prevention of HIV and AIDs in rural areas of Abia State. Materials and Methods This is a descriptive cross-sectional survey that was conducted between January and March 2020. Information was collected from 66 students of a community secondary school in the state. Participants were selected by a multi-stage sampling method and data were obtained using a semi-structured pre-tested questionnaire. Results Respondents consisted of 40(60.6%) females and 26(39.4%) males with ages ranging from 13 to 19. Some of the respondents 28 (42.4%), are living with parents while 24(36.4%) live with close relatives. A good number of the respondents 39(59.1%), accepted that their friends are HIV positive. Majority of them 49(74.2%) have not been approached for sexual relationships. About 17(25.8%) of the respondents accepted that they have boyfriends and girlfriends. Out of this number, 12(18.2%) of them said they have been approached for sex and only 2(3%) of them accepted having sexual relationships with the opposite sex. Finding showed that only 1(1.5%) of the respondents claimed to have ever used condoms during sex. Of the sexually active respondents, 49(74.2%) of them are aware that HIV is a virus infection caused by having multiple sex partners while 14(21.2%) were not sure whether HIV is a virus or bacterial infection. Conclusion The study revealed a gap in the knowledge of HIV prevention as well as inappropriate sexual behaviour among the respondents. Therefore, meaningful strategies that will be culturally sensitive to modify adolescent sexual risk behaviours should be adopted.

Cell Therapy as an Alternative approach for COVID-19 Infection Consequences: A Non-Systematic Review

The current uncontrollable outbreak of novel coronavirus (COVID-19) has unleashed severe global consequences in all aspects of life and society, bringing the whole world to a complete halt and has modeled significant threats to the global economy. The COVID-19 infection manifests with flu-like symptoms such as cough, cold, and fever resulting in acute respiratory distress syndrome (ARDS), lung dysfunction, and other systemic complications in critical patients are creating panic across the globe. However, the licensed vaccine has started to show up; some resulted in side effects that would limit its possibility in some circumstances as allergic personnel, for example. Moreover, the production and approval of new drugs is a very complicated process and takes a long time. On the other hand, stem cells have gone the extra mile and intensively investigated at preclinical and clinical studies in various degenerative diseases, including infectious ones. Stem cells are proposed as a broad-spectrum therapeutic agent, which may suppress the exaggerated immune response and promote endogenous repair by enhancing COVID-19 infected lung microenvironment. Also, stem cells have different application manners, either direct transplantation, exosome transplantation, or drug delivery of specific cytokines or nanoparticles with antiviral property by engineering stem cells. This review discusses and summarizes the possible emerging role of cell-based therapy, especially stem cell therapy, as an alternative promising therapeutic option for the treatment and control of novel COVID-19 and its potential role in tissue rejuvenation after COVID-19 infection.

Mathematical Modeling of Covid-19

Background The novel coronavirus (COVID-19) suddenly appeared in Wuhan, Hubei since December 2019, and quickly swept across China, then the whole world. Today, after more than 100 days of fighting against the virus, China's epidemic has been effectively controlled, but when we looking at the entire world, the novel coronavirus has rampaged globally, especially in the United States and many European countries. This paper mainly studies the impact of COVID-19 outbreaks at Hubei Province and the United States, fits the given data and predicts future trends. Methods Based on the theoretical basis of traditional differential equations and SIR infectious disease model1, and combined with the actual situation to improve the model. Hubei Province is modeled in different time periods, and the effects of birth rate and natural mortality on the model are analyzed. Since the birth rate and natural mortality in the United States in recent years cannot be found, the epidemic situation in the United States can only be analyzed based on the absence of births and natural deaths. Finally, we used Netlogo2 to establish a closed environment (Small World), and combined with known data to conduct simulation experiments on COVID-19 infection. Findings Through the analysis of given data through the SIR model, it is found that before the Chinese government has taken comprehensive measures to cure patients (before 10 February), the number of patients in Hubei Province will reach the peak at the end of February, and will gradually decline thereafter, and on 20 March, the epidemic will be effectively controlled in the future, which coincides with the fact that Wuhan closed the last mobile cabin hospital on 10 March. On the other hand, after the Chinese government tried its best to cure the patients (after 21 February), the number of patients continued to decline over time and will reach 0 in mid-April, which is also consistent with the actual data. According to the factors of birth and natural death, the sensitivity analysis of the above model found that when the epidemic situation is at its peak, it has little effect on the curve, but when the epidemic situation gradually flattens, it still has a certain effect on the trend of the curve. Finally, looking at the situation in the United States, due to the high transmission rate, the number of patients in the United States continues to rise and is expected to reach its maximum in mid-June. We also use Netlogo to simulate the environment in which the virus spread, and find that the general trend of the curves is also consistent with the actual curves. Interpretation The Chinese government has taken various measures to deal with the novel coronavirus pneumonia, including the establishment of two temporary hospitals and dozens of sheltered hospitals, the temporary transformation of university dormitories into isolation rooms345, the closure of Wuhan, the ban on the movement of people and so on. These measures have helped to reduce the spread of the virus and greatly increased the patient's cure rate. But the US government ’s actions are not as effective as China’s, not only because the government ’s actions are inappropriate and untimely, and the people’s opposition to isolation has not subsided. As a result, the virus has spread widely in the United States. More than one million people have been infected with the virus, and tens of thousands of people have died from COVID-196.

Effect of COVID 19 Pandemic on Stroke Care and Admission - Single Centre Study

Background By the start of year 2020, the whole world was attacked by a rapidly spreading epidemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) which later was classified by WHO as Pandemic. some physicians reported multiple neurological manifestations including cerebrovascular strokes in patients with severe infection. Aim to assess the incidence of admitted stroke cases during 2019 in comparison to 2020 during COVID-19 pandemic in King Fahd Hospital, Saudi Arabia. Methodology A record based retrospective comparative study was conducted by reviewing all medical records for patients who admitted with stroke at King Fahd Hospital during March and April 2019 and March and April 2020. All data were extracted from patients’ medical files included personal data, nationality, date of admission, and stroke related data. Results The study included 121 patients whose ages ranged from 33 to 98 years with mean age of 59.9 years. At March 2019, there were 45 cases compared to 26 in March 2020. In April 2019 there were 20 admitted stroke cases compared to 30 in April 2020. Regarding clinical features of admitted stroke cases, Table 3 illustrates that 36.9% of stroke cases in 2019 were small vessel stroke compared to 58.9% of 2020 cases. Conclusions & Recommendations In conclusion, the study revealed there was no recorded significant change in the trend of admitted cases with stroke before and during COVID-19 pandemic.

Models and data Analysis of the Outbreak Risk of COVID-19

With the spread of the new coronavirus around the world, governments of various countries have begun to use the mathematical modeling method to construct some virus transmission models assessing the risks of spatial spread of the new coronavirus COVID-19, while carrying out epidemic prevention work, and then calculate the inflection point for better prevention and control of epidemic transmission. This work analyzes the spread of the new coronavirus in China, Italy, Germany, Spain, and France, and explores the quantitative relationship between the growth rate of the number of new coronavirus infections and time. In investigating the dynamics of a disease such as COVID-19, its mathematical representation can be constructed at many levels of details, guided by the questions the model tries to help answer. Mathematical sophistication may have to yield to a more pragmatic approach closer to the ability to make predictions that inform public health policies. Background In December 2019 , the first Chinese patients with pneumonia of unknown cause is China admitted to hospital in Wuhan, Hubei Jinyintan , since then, COVID-19 in the rapid expansion of China Wuhan, Hubei, in a few months time, COVID-19 is Soon it spread to a total of 34 provincial-level administrative regions in China and neighboring countries, and Hubei Province immediately became the hardest hit by the new coronavirus. In an emergency situation, we strive to establish an accurate infectious disease retardation growth model to predict the development and propagation of COVID-19, and on this basis, make some short-term effective predictions. The construction of this model has Relevant departments are helpful for the prevention and monitoring of the new coronavirus, and also strive for more time for the clinical trials of Chinese researchers and the research on vaccines against the virus to eliminate the new corona virus as soon as possible. Methods According to the original data change law, Establish a Logistic growth model, we collect and compare and integrate the spread of COVID-19 in China, Italy, France, Spain and Germany, record the virus transmission trend among people in each country and the protest measures of relevant government departments. Findings Based on the analysis results of the Logistic model model, the Logistic model has a good fitting effect on the actual cumulative number of confirmed cases, which can bring a better effect to the prediction of the epidemic situation and the prevention and control of the epidemic situation. Interpretation In the early stage of the epidemic, due to inadequate anti-epidemic measures in various countries, the epidemic situation in various countries spread rapidly. However, with the gradual understanding of COVI D -19, the epidemic situation began to be gradually controlled, thereby retarding growth

Osteoarthritis, COVID-19 Social Isolation-Impacts, and Counter Solutions

Background to the Issue Many older adults, including those already suffering from chronically painful disabling osteoarthritis of one or more joints remain more susceptible than healthy age and gender matched adults to the COVID-19 corona virus. Aims This report sought to examine what has been published in 2020 on this health condition from the perspective of the variable of widely imposed social isolation strategies designed to mitigate the spread of this highly infectious disease, and to especially keep older community dwelling adults ‘safe’ from infection. Methods Reviewed were all articles published in 2020 in PUBMED from January 1-December 24, 2020 on osteoarthritis and COVID-19 isolation impacts, plus relevant past osteoarthritis and isolation literature among older adults. The focus was on ascertaining how social isolation and distancing strategies might impact current community-dwelling adults diagnosed with osteoarthritis and whether more should be done specifically to mitigate any potentially preventable ‘socially’ induced negative health impact among this group, in spite of the laudable goals of this public health strategy. Results Older adults with osteoarthritis living in the community who are asked to self-isolate, may incur more osteoarthritis pain and disability than would otherwise be encountered if actions taken to counter this possibility are not forthcoming. Advocated over and above basic care approaches are several psychosocial strategies including the role of mobilizing various forms of social support. Conclusion Data indicate a need for concerted thoughtful and immediate attention to offset isolation, fear, and anxiety and depression effects as part of a carefully devised integrated plan of management to reduce excess osteoarthritis disability, as well as excess COVID-19 risk among otherwise free living older adults already compromised by osteoarthritis.

Post Covid-19 Doctor-Patient Relationship Model. Creation of Social Connection Contexts With Physical Distancing

The coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 1 has produced a significant change in the way general medicine is conducted. This shift has been remarkably quick towards telecare. The form of the clinical interview has changed, and with it communication and the doctor-patient relationship; Before COVID-19, all communication techniques and doctor-patient relationship, which were considered tried and true to establish a good relationship with patients, involved physical proximity 2. Now in many European countries and in the United States face-to-face consultations have been reduced to 10-20%, with most contacts now being provided remotely using symptom checkers, electronic messaging, and phone or video consultations 3.

Assesses the impact of COVID-19 pandemic on the social and economic situation in Africa. The data use in this paper was generated from online survey questionnaire, in which the participants were asked about certain questions in which covid-19 affect their social-economic live. The questionnaire was design to help Africa to understand covid-19 impacts. The results reveal that covid-19 affected Africa; 1) 51.6% responded said that coronavirus affect their job search 2) Over the past three months, 47.1 percent of the respondents said their private financial situation remain unchanged 3) 61 percent did not trust the true existing of the Covid-19. 5) According to this online survey administered using Google form, 51.8 percent of the respondents said services sectors are most impacted sector pandemic, follow by industrial sector, 31.3 percent and agriculture is least sector at 8.4 percent. Policy implication is that it has serious impacts on social-economics interactions.

Potential Impact of COVID-19 Outbreak on Education, Staff Development and Training in Africa

Purpose This paper assess the impact of COVID-19 pandemic on Education, Staff development and Training in Africa. Online Research Methodology/Approach The data use in this paper was generated from online survey questionnaire, in which the participants were asked about certain questions in which covid-19 affect their social-economic situation. The questionnaire was design to help Africa to understand covid-19 impacts on their social and economic live. Results The results of this study reveal that coronavirus pandemic affected Africa in a number of ways; 1) 52.2 percent of the respondents said they should open school now in Africa, while 47.8 percent fear they should not open schools 2) 81 percent said before educational institution are closed there is public or official announcement that institutions must be closed due to pandemic—may be 3 months, ……,,…,, one week it depends on the severity of how covid-19 is spreading across the regions in Africa, 10.7 percent of the respondent said it may be and only 8.3 percent said it is not official announced.3) 65.4 percent of the respondents said government implemented an education response for continue of learning in Africa while educational institutions are closed 4) 61.5 percent said use of online/digital learning platform is the method for continuity of learning is currently available for children affected by closures of educational institutes provided by government, while 50 percent said television, radio, or podcast broadcast and 17.9 percent said assigning reading and exercises for home study. 5) 45.3 percent out of 100 percent said use of online or digital learning platform are the proportion of children affected by education institution closure. 38.7 percent said the proportion of children affect are the one that concentrate of using television, radio or podcast broadcasts to get academic content. 14.7 percent of the respondents are the proportion of the children affected by educational institute closure if they are assigning reading and exercises for home study. 6) 52.6 percent of the respondents from non-government organization, private schools said use of online or digital learning platform is the method for continuity of learning is currently available for children affected by closures of educational institutes, while 61.5 percent said use of online/digital learning platform is the method for continuity of learning is currently available for children affected by closures of educational institutes provided by government. The same thing government said as well. Similar respondents from government as do the non-government or private schools and 35.9 percent respondent said television, radio and podcast broadcast are method for continuity of learning is currently available for children affected by closures of educational institutes-provided by non-governmental organization, private schools etc, whereas 50 percent of the respondents said assigning reading and exercises for home study is the method for continuity of learning is currently available for children affected by closures of educational institutes-provided by government.7) 48.1 percent of the respondents said for the impact of covid-19 pandemic on staff development and training that their enterprise or organization partially suspended operation due to the pandemic and 34.2 percent of the responded said they completely suspended operation because of coronavirus pandemic and 16.5 percent said no closures on in operation for staff development and training because of pandemic. 8)According to the results of this question of the online survey, 49.3 percent said the challenges their enterprise face in delivery staff training programmes and activities using online learning or offline learning during covid-19 was due to infrastructure issues such the problem associated with internet and the like. The survey of the study also confirmed that 32.9 percent twice said limited digital skills of trainers and cost of staff training was a major setback to train staff in their enterprise or organization or department or establishment while 30.1 percent said it is due to limited digital literacy of users are the main challenges face by their department in order to train staff. Policy Implications The implication of the results from this online survey is that it has serious impacts on education closure and staff development and training. As educations are closed due to covid-19 pandemic, it will affect already problems of human capital that are hampering the development of Africa. Due to covid-19 pandemic, the achievement of sustainable development goals on quality education will be seriously halted. The government and the ministry in Africa should work hand in hand to solve the problems of children affected by schools closure after the pandemic by either additional hours or provide more study hours for schools to catch-up with what happened during the pandemic, the study noted. Originality/value The impact of covid-19 on education, staff development and training.

Effect of Hydroxychloroquine on Clinical Improvement and Mortality Among Patients with COVID-19 Admitted to Four General Hospitals in Saudi Arabia

Background The use of hydroxychloroquine in coronavirus disease (COVID-19) pandemic raised significant concerns as regards safety and efficacy in hospitalized patients. The objective was to examine the effect of hydroxychloroquine on clinical improvement and mortality among hospitalized patients with COVID-19. Methods A prospective cohort study was conducted at four general hospitals in the Western region, Saudi Arabia. Patients who had absolute or relative contraindication for using hydroxychloroquine were excluded. Patients concomitantly receiving other medications including azithromycin, antivirals, and supportive treatment were not excluded. Results A total 267 patients were included in the current analysis; 185 (69.3%) on hydroxychloroquine and 82 (30.7%) on non-hydroxychloroquine treatments. The average age was 46.0±13.3 years and 78.3% of the patients were males. Approximately 95.9% of the patients were symptomatic with mild (50.6%), moderate (32.6%), severe (8.2%), or ARDS symptoms (4.5%). Compared with no hydroxychloroquine, those on hydroxychloroquine had significantly longer length of stay (11.5±7.1 versus 7.8±4.3 days, p<0.001), more ICU admission (22.7% versus 9.8%, p=0.012), and more intubation (12.4% versus 3.7%, p=0.026). Improvement of symptoms (84.3% versus 81.7%, p=0.595) and hospitalization death (7.0% versus 1.2%, p=0.071) were not significantly different between groups. With exception of length of stay, the association of hydroxychloroquine with the above negative outcomes disappeared after adjustment for several factors including disease severity and concomitant use of azithromycin. Conclusions Hydroxychloroquine is not associated with better improvement of symptoms compared with other treatments. Moreover, it is associated with longer length of stay but not mortality or ICU admission in adjusted analysis.

COVID-19, and Vitamin D, and Air Pollution Global Epidemics Impact on Older Adults

Background Most current Corona virus or COVID-19 pandemic deaths have been found to occur among populations older than 65 years of age, who often suffer from the presence of an array of chronic diseases that may be related to a co-occurring vitamin D deficiency. Another factor affecting older adults’ immune response mechanisms is air quality. In turn, air quality can impact the absorption of vitamin D from sunlight sources, a factor which could explain why older people, who are often vitamin D deficient, may be more likely than younger adults or healthy adults to be at risk for COVID-19 and poor outcomes. Aim This work was designed to examine the recent literature on COVID-19, vitamin D and air pollution and what it might imply for public health workers, policy makers, and others. Methods Available data accessed largely from the PUBMED data base for the year 2020 using the key words COVID-19, air pollution, and vitamin D deficiency were sought and selected items were carefully examined and documented in narrative and tabular formats. Results Many publications on COVID-19 prevail, but far fewer focus specifically on vitamin D deficiency and its possible role in explaining COVID-19 global health risk among older adults. A similar, albeit small number of publications, discuss the global pandemics of air pollution and its possible COVID-19 association, as well as its impact on vitamin D production. However, while most related articles support a possible independent as well as a dual role for both factors in COVID-19 the realm of this highly infectious widespread disease, very few actual studies have been conducted to date on any of these topical issues Conclusion More research to examine if vitamin D-based nutrients or supplements may provide some degree of community wide protection against COVID-19 in the older vitamin D populations, especially among those living in highly polluted areas may prove highly valuable. Controlling air pollution emissions globally and locally may also prove to be a highly impactful public health approach to reducing overall COVID-19 risk, and extent, and warrants study.

Can Vitamin D Positively Impact COVID-19 Risk and Severity Among Older Adults: A Review of the Evidence

Background The coronavirus Covid-19 strain that emerged in December 2019, continues to produce a widespread and seemingly intractable negative impact on health and longevity in all parts of the world, especially, among older adults, and those with chronic health conditions. Aim The first aim of this review article was to examine, summarize, synthesize, and report on the research base concerning the possible use of vitamin-D supplementation for reducing both Covid-19 risk and severity, especially among older adults at high risk for Covid-19 infections. A second was to provide directives for researchers or professionals who work or are likely to work in this realm in the future. Methods All English language relevant publications detailing the possible efficacy of vitamin D as an intervention strategy for minimizing Covid-19 infection risk published in 2020 were systematically sought. Key words used were: Vitamin D, Covid-19, and Coronavirus. Databases used were PubMed, Scopus, and Web of Science. All relevant articles were carefully examined and those meeting the review criteria were carefully read, and described in narrative form. Results Collectively, these data reveal vitamin D is a powerful steroid like compound that is required by the body to help many life affirming physiological functions, including immune processes, but its deficiency may seriously impact the health status and well being of the older adult and others. Since vitamin D is not manufactured by the body directly, ensuring those who are deficient in vitamin D may prove a helpful overall preventive measure as well as a helpful treatment measure among older adults at high risk for severe Covid-19 disease outcomes. Conclusions Older individuals with chronic health conditions, as well as healthy older adults at risk for vitamin D deficiency are likely to benefit physically as well as mentally, from efforts to foster adequate vitamin D levels. Geriatric clinicians can expect this form of intervention to reduce infection severity in the presence of Covid-19 infection, regardless of health status, and subject to careful study, researchers can make a highly notable impact in this regard.

Controlling the Covid-19 Pandemic without Killing the Economy: About Data Driven Decision Making with a Data Model Assessing Local Transmission Risk

Context In the face of further waves of the COVID-19 pandemic it becomes essential to find a balance between protective actions to guard public health and restrictive measures which can collapse our economy. Background As a basis for public health decisions, officials still rely on metrics which were helpful in the beginning of the pandemic but are now not precise enough for a focused and targeted approach to keep the spread of the infection under control. This can lead to public mistrust, “pandemic tiredness”, and can cause unnecessary damage to the economy without having the desired protective effect on public health. Methods This article discusses various metrics, their advantages and caveats, and it provides suggestions for use in a more targeted and risk-based approach, as an alternative to the current “general lock-down” practice. It suggests the notion of including a concept of “risk contacts per area” to better describe the possibility of virus transmission than currently published metrics do. The article also suggests specific analyses of real-world data for identification of populations at risk for severe courses of COVID-19 to allow more targeted protective actions. Discussion Data currently used to describe the COVID-19 pandemic lack important parameters like population density and local likelihood of potentially infectious contacts. The currently often used “all or nothing” approach of shut-down orders needs to be replaced by more sophisticated tactics considering individual local exposure risks and need to be balanced towards metrics on economic short term and long-term impact. In addition, smart analyses of real-world data may contribute to effective protection of individuals at risk.

Awareness of Cervical Cancer Screening test Among Women of Child Bearing age in the Rural Area of Awo-Omamma, Imo State, Nigeria.

Introduction This study assessed the awareness of cervical cancer screening test among women in the rural area of Imo State. Cervical cancer is the fourth most common cancer and the cause of death in women. The need to ascertain the level of awareness of cervical cancer screening test and the level of uptake among rural women motivated this study. Materials and Methods The study design was cross sectional descriptive survey. The sample for the study, which was statistically determined by Taro Yamane formula was 420. Administered structured questionnaire was used for data collection. Data were analyzed using frequency distribution tables. Results The result showed that 270(64.3%) of the respondents were aware of cervical cancer screening test and only 135(32.1%) used cervical cancer screening test . Majority of the respondents, 400(95.2%) have never taken vaccination for human papilloma virus . The main place where 234(55.7%) of the respondents learnt about cervical cancer screening was the hospital. A good number of the respondents 225(53.6%), had low uptake services because of the views that cervical cancer screening is mainly for the elderly women, and also 140(33.3%) felt that the investigation process is painful. Conclusion Therefore, adequate and substantial measures should be taken to health educate women on benefits of cervical cancer screening tests.

Risk Management and Organizational Resilience: Analysis of the Italian Scenario During Covid-19 Pandemic, with A Look at the Challenges of Technology and Sustainability

The Coronavirus emergency represents an epochal challenge for all world health organizations. In these times of profound destabilization of healthcare organizations, become urgent some thoughts on how to deal with the organization and re-engineering process as well as on concepts, relatively new, such as "resilience" and "business continuity". The company management need having to predict, design and plan a profound process of change in their Clinical and Corporate Governance. With the implementation of phases 2 and 3 of management of the pandemic and the coexistence of doctors and citizens with the new Coronavirus, it has become a priority to develop territorial models of assistance to established or suspected Covid patients, starting with the creation of monitoring networks based on the model of the “sentinel” general practitioner. One of the main concerns of Healthcare, since the beginning of the Covid-19 emergency has been to get closer to the citizen-patient. It is therefore necessary to find stimuli to restart with new methods of care, new health and social-health services, moving the current care paradigm for Covid-19 from the hospital to the territory, optimizing the constituent elements of the districts, primary care and general practice in a multidisciplinary approach.

Dynamics of Infections and Number of Vaccines Needed to Avoid Covid-19 in Europe

The work analyzes the dynamics of transmission of infections by the new coronavirus in twelve European countries, including France, Germany, Italy, Spain, UK, Austria, Croatia, Denmark, Greece, Romania, Czech Republic, and Portugal, whose data from contagion were obtained by Johns Hopkins University until September 24, 2020. The study confirmed that this new coronavirus (SARS-CoV-2) surprised all the countries of the world that had to improve their public health policies to confront this disease according to the results obtained from the calculation of the mantissa. Although the countries were able to improve their policies after the first wave of contagion, Spain and France have the highest proportion of cases that stand out significantly with the rest of the countries in the second wave of infections that the world faces again. Likewise, the beginning of the epidemic outbreak was determined, which could help to track the spread of the disease through European countries (not the first case registered in each country), from which it can be inferred that the outbreak begins in Italy and later the rebound begins in Germany, France, and Spain. Within days, it significantly affects Greece and Austria, reaching Denmark, the Czech Republic, Romania, and Croatia. Finally, the number of people who must be vaccinated to counteract the advance of Covid-19 in these European countries was determined based on the calculation of the Effective Reproductive Number, Rt. The number of people that would have to be vaccinated in all these countries to counteract this disease sums up to 206.830.361.

SARS-CoV-2 affected cells Pathogeny and Therapy

There were compared mechanisms infecting a human organism by different viruses in relation to interaction between human diploid cellular cycle mechanisms and coronaviruses haploid genomic mechanism. Besides there were described mechamism forming combined haploid-diploid cellular cycle of viral affected cells due to interactions between human cellular cycle mechanisms and coronaviruses genomic mechanism. Further there were considered infected way of SARS-CoV-2 from mechanism maintenance stability Internal Energy of an organism’s able-bodies cells and transmutation them into viral affected cells leading to death of affected cells of high respiratory level in nose-trachea-bronchi with transiting coronaviruses through dead cells‘ wall and infecting lungs‘ cells. Taking into account great searches of methods treatments Coronaviruses infected disease, we offered to approved through detail clinical Trial of new efficient method of treatment ill patients with SARS-CoV-2 disease which can rescue of still alive lungs‘ cells. Moreover there was reviewed offered therapy of SARS-CoV-2 induced disease.

Perception of Health Care Professionals on Transplantation in the Treatment of COVID-19 Patients

Corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) has rapidly evolved as a pandemic with a challenge to the entire world for its management. Various modalities of treatment have been tried till date and when all the modalities failed then the only option that has been shown to be successful in some cases is lung transplantation. Decision for Solid-organ transplantation is not only made based upon its therapeutic requirement but also need to be supported by the law of land. In this regard, current Nepalese law is not with the provision for lung transplantation.  Thus, in order to make the concerned authorities aware of it and also as a step toward the preparedness for COVID-19 pandemic, this research has been conducted with an aim to see the perception of health care professionals of tertiary care centre of eastern Nepal regarding the legal aspects of lung transplantation. Conclusion Outcome of this research has supported the therapeutic aspect of transplantation over its legal issue in the emergency conditions like COVID-19 Pandemic.

Physical Exercise as a Means of Managing Covid-19; an Insight Review

The following document provides important information that everybody know about physical exercise as a means of managing COVID-19. It addresses the health benefits of physical exercise on our body’s immune system, and stress reduction. Already today in the entire world, coronavirus is now the leading causes of morbidity and mortality. It kills thousands of peoples per day worldwide and continues its impact on the governments and the society. Nowadays it is the greatest public health problem in most countries in the world. Since its identification on Jan, 7 by the chines scientists named the pathogen as a novel coronavirus. In the current situation COVID-19 is rapidly spreading worldwide and the number of cases and deaths are rising up speedily. The spread of the virus is a headache to the government in general and the society in particular. The nature of the virus disallowed contacting with one another, working together, meeting, and other activities the majority of government and private business organizations are enforced to discontinue their work. The growing burden of the virus would place millions of jobs at risk an additional 8.8 million people in working poverty around the world. The danger of the disease and loss of employment leads the majority at stress. A chronically stressed person impairs the organism’s ability to mount a strong immune response with a resultant increase in morbidity and mortality.

Animals in the COVID-19 Era: Between Being a source, Victims, or Maybe our Hope to Overcome it!

The indirect misuse of animals usually correlated to catastrophic consequences like the one we are facing now, novel coronavirus disease-19. However, the source of infection is not fully confirmed yet. But the finger of blame points to bats and pangolins. Hence, understanding and raising awareness about wild animals and the consequences of their misuse are a must to avoid future pandemics. Herein, we threw light on the most animals involved in the current epidemic as well as possible animals in the shadow. Random serological investigations of samples from animals of different species (including asymptomatic animals) are required to understand the prevalence and severity of the infection, the extent of the transmission, and the monitoring of the situation over time. Moreover, alleviating fear associated with the possibility of human infection from their pets, we highlight that there are no reports that confirm this hypothesis; however, the opposite has been reported. Similarly, there is no proof that pigs can become infected amplify or spread novel coronavirus.

Genetic-Mathematical Modelling of the Populations Interaction

The solution of a genetic-mathematical problem of interaction of the human population cells and virus population to a problem of pandemic COVID-19 is submitted. The mathematical model based on the Hardy - Weinberg law consisting of two interdependent differential equations is used. The equations reflect time dynamics of the human cells and virus populations during their interaction. Solutions of the differential equations are found and results of these solutions are analyzed. The estimation of duration pandemic is received at use of parameters of the human liver cells and a flu virus.

Reducing COVID-19 Risk through Dietary Supplementation of Plant Mannose Binding Lectins

Mannose binding lectins (MBL), a key molecule in our innate immune response, contributes to host defense against coronaviruses such as SARS-CoV. This article reviews the role of MBL in the innate immune response against coronavirus infections, highlights evidence of MBL’s significance, and suggests dietary MBL supplementation through increased consumption of fruits and vegetables as an accessible and viable approach to minimizing COVID-19 infection risk. Increasing consumption of plant lectins (e.g., eating fruits and vegetables) may reduce COVID-19 risks.

The Prevalence of Osteoporosis in Hiv Infected Patient and its Correlation with Cd4 Count/Clinical Staging in Indian Population

Human immunodeficiency virus (HIV) is a retroviral disease in which the viruses copy their genetic material into the genetic material of the human beings. Infected cells remain infected for the whole of their life. First discovered in the year 1981, Human immunodeficiency virus infections is considered to be a pandemic by the World Health organization.
