The goal is to do a text mining analysis of all scientific publications and find out what journal and what aspects are studying about the conspiracy theories of Covid-19. For this purpose, all publications available in the National Center for Biotechnology Information (NCBI) database were consulted as they were peer-reviewed papers. Of all these papers, only the abstracts of each one were studied using artificial intelligence techniques to determine, for example, whether the subject is of importance depending on the journals where it has been published, and above all, what possible relationships could be extracted from the information published in them. In addition, the "Net Prevalence per Covid19" index was definedin those countries with a high value, greater campaigns should be sponsored to avoid the misinformation generated by Covid-19, although this comment should be verified in future publications. The main challenge was to unify the abstracts and for this purpose, a text summarizer was used under artificial intelligence schemes. The results obtained indicate the tendency of certain topics by the frequency of the words obtained where the focus on the conspiration are the Covid-19 vaccines, but further work is still needed to continue working on this methodology to unify the results.

In this study, flow hemodynamic parameters and settling of LDL particles in healthy ideal and ideal with stenosis coronary artery have been studied using the Open FOAM software. Not only the effect of movement of the vessel on particles depositions have been studied, but also both non-Newtonian and Newtonian behaviors of blood have been investigated. The particle's motion and deposition have been simulated. It has resulted that only in small vessels, non-Newtonian behavior of blood can be seen and in bigger vessels, there is no remarkable difference between two Newtonian and non-Newtonian models. Vessel movement has no important effects on entered shear stress on its wall, but the alteration in flow lines causes a 70% increment in particles depositions on a vessel with stenosis. This shear stress has no considerable changes with inlet velocity alteration, but it has intensive dependence on geometry in the vessel with stenosis (13 times more oscillation in stenosis location than a healthy vessel).

In this research work Mg0.45Mn0.55-xNixFe2O4 ferrite particles of varying compositions (x=0.05, x=0.15, x=0.25, x=0.45 and x=0.55) were synthesized using cost effectual co-precipitation route. The synthesized ferrite particles were characterized by collection of techniques. XRD analysis confirmed the formation of cubic spinel structure of the ferrite particles. SEM and AFM analyses illustrated the morphology and size distribution of obtained ferrite particles. FT-IR study exposed that the absence of any additional peak related to second phase. VSM results indicated magnetic analyses such as saturation magnetization (MS), Coercivity (HC) and Remanence (Mr) of ferrite particles. The major objective of the present investigation is to synthesize MgMnNiFe2O4 ferrite particles on cotton fabrics in order to obtain finished fabrics; it is very significant in biological applications. The antibacterial activities of the ferrite particles coated cotton fabrics were tested against selected Gram positive and Gram negative bacteria which showed tremendous results via formation of inhibition zones. The fabricated ferrite particles on cotton fabrics showed great durability evidenced by their antibacterial activities even after 20 washing cycles. Hence, the functionalized cotton fabrics could be used as potential antibacterial agent.

The strategy for safe drug discovery and development has limited clinical success as compared to wasted time and resources annually. This is due to the fact that the results of multiphase preclinical trials are less likely to make an accurate early prediction on the safety of test compounds to progress into the clinic as a valuable therapeutic agent. A lot of time and resources has been wasted in the multistage processes of drug discovery and development that does not work at the end of the procedure every year. During pre-marketing stage, for instance, the number of unsuccessful clinical trials are greater than the successful one because of safety issues. A toxicity study at different stages of preclinical and clinical trials is a routine procedure to investigate the undesirable side effects of test compounds being manifested on the natural processes of living things. It deals with the effect and mechanism of toxicity of test compounds that triggers different biological responses on different organ systems. The biological responses that would be manifested as a result of interaction between the receptors and active molecules of a test compound could be desirable pharmacological effect or undesirable side effect or both responses are manifested simultaneously depending on the selectivity or specificity of the molecule of a test compound for its receptor subtype which makes safe drug discovery and development very challenging. The response efficiency of the body (the net outcome of the body’s biological reaction against the side effect) would determine the potency of a test compound to manifest undesirable pharmacologic effect. In other words, the amount of a drug required to cause a biological harm or injury depends on the magnitude of the body’s biological reaction in which the immune response plays a great pharmacological role by neutralizing and harmonizing xenobiotics with the biological molecules. The dose of a test compound at 100 mg/kg body weight, for instance, could be lethal to some of the study animals while it is still non-lethal to some other study animals depending on the response efficiency of the body. The immune system is well connected to each and every biological systems of the body which allows it to detect undesirable side effects being manifested through immunoglobulins signalling and activation mechanisms. This complex communication network helps to localize the diverse side effects of a test compound being manifested on different organ systems into the immune system which makes a toxicity study relatively simple to monitor. The cellular immune system becomes active following the molecule-receptor interaction and start producing antibodies which is also known as immunoglobulins to protect bodily harm and destruction. Under normal biological circumstances, the amount of immunoglobulins produced by the cellular immune system following exposure to a test compound is proportional to the number of harmful molecules interacted with its receptor subtype. Thus, with the reference to the changes in the immune response against the administered dose, it would be able to deal with the diverse undesirable side effects of a test compound being manifested on treated study animals using computational systemic biology.

Objective Evaluation of the ability of autogenous Platelet Rich Fibrin (PRF) and Zinc Oxide Nanoparticles (ZnONPs) to repair critical-sized ulnar defects in rabbits based on radiographic assessment. Design Randomized controlled study. Animals Twenty-four healthy male white New Zealand rabbits with an age of 6.0 ± 0.3 months and weight of 2.5 ± 0.29 Kg were used. Procedures A 12 mm defect was created in the diaphysis of the right ulnae in allrabbits,then the rabbits were randomly allocated into three groups (8 each): Control group, (the defect left for healing without grafts), platelets rich fibrin group (PRF group, the defect filled with PRF) and combination group (PRF/ZnONPs group, the defect filled with both PRF and ZnONPs). Healing capacity between the groups was evaluated by immediate postoperative radiographic assessment and subsequently at the first and the second postoperative months. Results Statistical analysis showed significant differences in the radiographic healing score between the groups (P = 0.000) at all-time points (P = 0.000- 0.003) during the study. Rabbits in the combination group showed the highest radiographic healing scores followed by the PRF group meanwhile, the Control group showed minimal radiographic healing scores. Conclusion and Clinical Relevance The addition of ZnONPs to PRF can accelerate the healing of ulnar critical-size defects in rabbits.

Mendelevium nanoparticles absorb energy of descendent light and generate some heat in the particle. The generated heat transferred to the surrounding environment and leads to increase in temperature of adjacent points to nanoparticles. Heat variations can be obtained by heat transfer equation. In the current study, thermoplasmonic characteristics of Mendelevium nanoparticles with spherical, core–shell and rod shapes are investigated. In order to investigate these characteristics, interaction of synchrotron radiation emission as a function of the beam energy and Mendelevium nanoparticles were simulated using 3D finite element method. Firstly, absorption and extinction cross sections were calculated. Then, increases in temperature due to synchrotron radiation emission as a function of the beam energy absorption were calculated in Mendelevium nanoparticles by solving heat equation. The obtained results show that Mendelevium nanorods are more appropriate option for using in optothermal human cancer cells, tissues and tumors treatment method. When Mendelevium nanoparticles are subjected to descendent light, a part of light scattered (emission process) and the other part absorbed (non–emission process). The amount of energy dissipation in non–emission process mainly depends on material and volume of nanoparticles and it can be identified by absorption cross section. At the other hand, emission process which its characteristics are depend on volume, shape and surface characteristics of nanoparticles explains by scattering cross section. Sum of absorption and scattering processes which lead to light dissipation is called extinction cross section.

Dental implant restoration is challenging procedure when it involve the esthetics zone, and since implant dentistry is prosthodontically driven procedure, care were practice in restoration of missing teeth in esthetics area which will fulfill the objective. Extraction of teeth leave buccal plate bone unsupported and decrease the blood supply and since this plate is very thin resorption will be expected. Different attempt was done in order to prevent this sequence and create natural emergence profile around dental implant prosthesis. Socket preservation procedures were introduced, however in case of ridge deficiencies, hard and soft tissue augmentation procedures are indicated. Socket shield technique meets the demands of minimal invasion, tissue preservation, and no need of bone substitute materials. And can be applied not only for maintaining buccal contour of an edentulous ridge but also for keeping the inter-implant soft and hard tissue In this review paper we present different articles and case report using socket shield technique as treatment protocols and try to explore different protocol are practice in order to achieve high treatment out come with optimal success.

Background: Oral ingestion of zinc oxide nanoparticles (ZnONPs) may lead to serious liver injury. Vitamin E (VE) is an important antioxidant factor that can reduce such damage. Aim: This study aimed to evaluate the possible changes that could take place in the liver of adult male albino rats after oral ingestion of ZnONPs and elucidate the potential protective role of VE against such damage. Material and Methods: Forty eight male albino rats were divided into four groups of 12 animals each. Group (1) served as control group and received normal saline. Group (2) “VE-treated” received 100 mg/kg/day of VE dissolved in normal saline by oral gavage for 21 days. Group (3) “ZnONPs-treated” received a daily dose of ZnONPs dispersed in the fresh sterilized physiological saline solution 1mg/kg for 5 constitutive days. Group (4) “concomitant ZnONPs and VE-treated” was pretreated with VE 100 mg/kg/day for 14 days followed by the same dose of ZnONPs as in group (3) for 5 days. The extent of hepatic damage was evaluated by histological and immunohistochemical examination of liver samples and serological analysis of liver enzymes. Results: Body weights and liver weights showed very highly significant decrease (P <0.001) in the ZnONPs-treated group. The histological results in ZnONPs-treated group revealed congested dilated central veins and blood sinusoids, loss of normal arrangement of hepatocytes and most of hepatocytes showed marked vacuolated cytoplasm with darkly stained nuclei. Portal area affection was in the form of congested dilated portal veins with bile duct hyperplasia and cellular infiltration. There was an increase in the mount of blue stained collagen fibers around central veins together with strong positive reaction for Caspase 3 in ZnONPs-treated group. Similarly biochemical analysis indicated that the levels of serum aminotransferase (AST &ALT) significantly increased in ZnONPs-treated group when compared with other groups. Rats pretreated with VE showed improvement of the histological findings and biochemical parameters. Conclusion: Ingestion of ZnONPs could be associated with serious liver affection and pretreatment with VE is suggested to induce some improvement of such deleterious changes.

This narrative literature review investigates the clinical feasibility of maxillary sinus lift using the lateral window (or traumatic) technique, employing a grafting material composed of hydroxyapatite associated with beta-tricalcium phosphate. The study is based on the premise that bone resorption and sinus pneumatization—common in edentulous posterior maxillae—pose a challenge to achieving primary stability during dental implant placement. Given the limitation imposed by reduced residual bone height, bone-grafting surgical techniques become necessary to enable implant-supported rehabilitation. The objective of this work is to analyze, through a literature review, the efficacy of combining synthetic biomaterials as an alternative to autogenous bone grafts, which are considered the gold standard in implant dentistry. A bibliographic search was conducted in the PubMed and LILACS databases and through the VHL portal, prioritizing articles addressing the biological properties of alloplastic grafts, the indications of the lateral window technique, and the clinical success rates of implants placed in previously grafted areas using such materials. The findings demonstrated that hydroxyapatite associated with beta-tricalcium phosphate exhibits favorable osteoconductive characteristics, such as adequate porosity and gradual resorption, while allowing the formation of viable bone within a clinically acceptable timeframe. The combination of these materials eliminates the need for a second surgical site, reduces morbidity, and maintains treatment predictability. It is concluded that the lateral window technique associated with synthetic biomaterials is a safe and effective alternative for patients with maxillary bone atrophy, capable of promoting suitable bone beds for dental implant placement and stabilization, with lower surgical risk and satisfactory clinical outcomes.

Objective The goal of this systematic review is to identify common themes amongst acute spinal cord injuries (SCI) in equestrian athletes. Design A systematic review was performed using PubMed, CINAHL Plus with Full Text (EBSCO), Cochrane Library, and Scopus with pre-determined MESH terms. The initial search returned 354 studies. Following PRISMA guidelines, 13 articles were included. Exclusion criteria included injuries to the horse only, non-English language, cauda equina, and case reports. Data extraction was completed, and common findings were evaluated narratively due to heterogeneity of data. Results Seven manuscripts listed specific horse-related activities that caused SCI, with fall from horse as the highest percentage of injury. Nine articles identified the injury region, with large variations and no clear dominant area of injury. Five articles identified the length of hospital stay with ranges from 1 to 82 days. Four articles looked at the association of professional vs non-professional riders. Only two articles evaluated helmet use at time of injury, with one article showing 81% of those with SCI used helmets, and the other showing only 35.6% utilized this safety measure. Conclusion SCI in equestrian athletes can have a wide presentation, with large variation on location of injury, length of stay, and other factors. However, non-professional riders are at greater risk of SCI and individuals are more likely to sustain injury from a fall from a horse rather than a kick or another modality of injury. Future study can elicit presenting symptoms, types of surgical intervention used, and long-term outcomes and recovery.

Ayurveda is a traditional and scholarly medical system practiced in South Asia since the Vedic period. It integrates science and philosophy to promote a healthy, happy and prosperous life. Ayurvedicbhasmas are classical formulations that contain non-toxic forms of metals and minerals, enriched with therapeutic metabolites. These bhasmas are produced through repeated trituration of metals and minerals with the extracts from potent Ayurvedic herbs, followed by intense heating at temperatures above 650 °C. The preparation process of bhasmas closely resemble top-down approach in nanoparticle synthesis, resulting in very fine calcined nano-powders. These powders are used effectively in Ayurvedic treatments for various ailments, particularly chronic diseases. Recent studies have highlighted that bhasmas possess antioxidant, anti-inflammatory, antibacterial, antiviral and antitumor properties and may serve as potential carriers for drug delivery. This paper aims to compare bhasma particles prepared by traditional and modern methods, explore the therapeutic benefits of different bhasmas, and investigate the nanomedicinal features of various Ayurvedicbhasmas.

High rates of workplace psychological stress and burnout have been chronic among Healthcare Practitioners. Research shows that Healthcare Practitioner psychological stress / burnout is related to poor quality of care and a high probability of making medical errors and mishaps resulting in harm to patients and even workers themselves. In response, relatively impactful programs have been developed to address Practitioner burnout. To derive a better understanding of the subject and inform best practices and policy regarding the problem and its fixes, this article reports findings from a novel study of a systematic (PRISMA-based) literature review of current (circa ~10 years <) literature reviews; or a distillation of reviews already at 100 proof then undergoing a further distillation into a review of 200 proof.* This study employed a grounded theoretic qualitative methodology to iteratively generate and enumerate descriptive themes from the study’s literature review articles. This article reports on what is currently known regarding the precipitants of Health Practitioner Burnout, Burnout itself, its relationship to Safety lapses and mishaps, and Programmatic Interventions (i.e., Fixes). The primary conclusion is that Health Practitioners are the foundation of healthcare organizations and key to quality care and management / leadership should be concerned for their wellbeing; and this article provides a general blueprint in terms of addressing burnout and safety. Study Limitations and Future research are also discussed.

In response to the rising burden of non-communicable disease (NDC), the World Health Organization (WHO) developed tools to enable early detection and management of NCDs in Primary Healthcare centers (PHC). Globally, the prevalence of NCDs remains alarmingly high with 41 million deaths annually. Of these, 17 million people die before the age of 70, and 86% of these premature deaths occur in low-and middle-income countries. This narrative review aimed to assess the effect of PHC services on health-related quality of life (HRQoL) of older persons with NCDs, to critically analyze the potential of the existing literature in informing improvements in PHC services. We searched various databases (PubMed, Springer, Scopus, and ScienceDirect) for relevant literature. Peer-reviewed articles on the influence of PHC services on HRQoL among older persons with NCDs written and published in English between January 2013 and May 2024 were considered. The review indicates that effective PHC services are linked to good HRQoL. However, PHC services are sub-optimal and poor in low- and middle-income countries, hence more health interventions are essential to improve PHC services to enhance HRQoL of older persons.

This exploratory study investigates factors and consequences of underdiagnoses or late diagnoses of attention deficit hyperactivity disorder (ADHD) in females favoring males in the referral, diagnosis, and treatment processes resulting in gender disparities. A literature review in PubMed, PsychINFO, PsychArticles, and PsychiatryOnline from 2010 to 2023 underscores significant implications of delayed ADHD diagnosis in females, hindering timely access, support, and interventions during critical developmental years. Factors associated with underdiagnosis of ADHD among girls include gender differences in symptomology presentation, comorbidity, and gender bias among parents, teachers, and healthcare providers. We highlight the role of ethnicity and cultural factors. This bias prevents girls from receiving necessary ADHD support and treatment, impacting their health, social, and economic outcomes into adulthood. We summarize strategies to urgently address gaps in ADHD research and practice. Raising awareness among communities, healthcare providers, educators, and parents is vital to alleviate these gender disparities. By illuminating factors contributing to delayed diagnoses, the study informs policymakers and stakeholders, facilitating targeted interventions to improve early detection and treatment outcomes for females with ADHD.

Knee joint osteoarthritis, a chronic condition resulting in considerable disability, particularly in later life, not only impacts life quality significantly and severely, but is also strongly associated with the persistence of intractable pain, depression, helplessness, and a high falls injury risk. This narrative overview synthesizes the knowledge base regarding painful knee osteoarthritis and what is known about Tai Chi exercise participation in the context of reducing knee joint disability and its associated risk of one or more injurious falls, as well as pain and depression. To this end, all relevant articles published in the English language on the topic were sought. While most reports rely on Eastern observations, rather than Western medicine studies, collectively, these data reveal that Tai Chi practiced widely in Asia for many centuries may have an enormous positive impact on reducing distress and increasing function and autonomy among older adults living in the community and diagnosed as having knee osteoarthritis. They specifically suggest the increasing numbers of older adults diagnosed as having knee osteoarthritis can safely practice selected Tai Chi exercises with the expectation that consistent applications will enhance mobility, reduce pain and depression, plus instability and possible injurious falls, while reducing fatigue, even if surgery is forthcoming.

Background Osteoarthritis and depression are both key barriers to healthy aging and greatly heighten the risk for many negative health issues that seriously impact life quality. When combined what are the implications? Aim This mini review examines 2023 data pertaining to osteoarthritis and depression and older adults and a possible theoretical framework of stress that may direct our approaches in the future. Methods and Procedures Articles published between January 1 and August 15 2023 that addressed the current topic of interest and that were extracted from PUBMED, PubMed Central, Science Direct, and Google Scholar were carefully read and their key points arepresented in narrative form. Results As in the past, very few tangible theory-based prospective analyses that employ valid measures of depression and examine any association of any form of osteoarthritis longitudinally and in a consistent manner prevail. Several reports use the same or similar large cohort to draw upon, and find various degrees of clinical implications, but this may not embrace the need for more inclusivity, sampling strategies, control and diversity issues, as well as embracing the role of cognitions positive and negative. Conclusion Without efforts to develop sound research designs of diverse and carefully differentiated osteoarthritis substantive samples it is impossible to delineate the origin or implications of the osteoarthritis-depression linkage reported currently or arrive at a deep understanding of its relevance, to life quality and public health costs. What is needed to protect against or minimize either or both these clinically related disabling correlates in the aged population warrants timely study.

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.

The increasing demand for environmentally-friendly materials has led to a surge in research on the production of biodegradable polymers. In this study, we investigate the synthesis of a biodegradable polymer by graft copolymerization of gum Arabic (GA) and polyethylene glycol (PEG). GA, a natural polysaccharide and PEG, a synthetic water-soluble polymer, were used as the backbone and graft monomer, respectively. The graft copolymerization was carried out using benzoyl peroxide as an initiator and performed under nitrogen atmosphere. The resulting polymer was characterized by Fourier transform infrared (FTIR) spectroscopy, Xray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The FTIR spectra confirmed the formation of the graft copolymer, and TGA analysis showed that the copolymer had higher thermal stability than GA. The DTA thermograms indicated two thermal events. The evaporation of water and organic polyethylene glycol components was measured, and the first mass loss was due to the loss of adsorbed and structural water in the gum Arabic, which occurred between 31.87 and 180°C, while the second, corresponding to the pyrolysis of polyethylene glycol functional groups and polysaccharide decomposition, resulted in a 70% mass loss. SEM morphological analysis of gum Arabic showed aggregates of high irregularity in particle shape. The cracks and holes obtained in the Gum Arabic micrograph disappeared from the new gum Arabic-graft-polyethylene glycol, leaving a smooth surface with scattered particles in the image, which was due to the grafting copolymer. From the XRD patterns, the percentages of the amorphous and crystalline phases were determined. The results show that gum Arabic has a 78% degree of crystallinity, whereas gum Arabic-graft-polyethylene glycol has the lowest value of 51%. Biodegradation activity was observed using the fungus Aspergillus flavus on different days on gum Arabic-g-polyethylene glycol. The results clearly showed inhibition zones with a change in the state of the copolymer from solid to liquid from days 8 to 14. These results indicate that the GA-PEG copolymer has potential as a biodegradable material for use in various applications, such as packaging, agriculture, and medical industries.

Background Ageing is a life process in which progressive molecular, cellular, physiological and anatomical changes manifesting in humans and animals including other organisms lead to the decline of biological functions. Immunoglobulins (Igs) are glycoprotein molecules produced by white blood cells mainly B lymphocytes following signal transduction as a result of their interaction with pathogenic microbes or poisonous substances introduced into the body systems. They elicit responses against the side effects of pathogens and poisons in which their response efficiency usually declines as we are ageing. Objective Thus, the similarities between Igs’ immune response against the different amounts of xenobiotics and the biological changes associated with ageing have been systematically assessed using the reports of different study results on humans and animals. Methods First, a literature search was carried out in google, PubMed and google scholar using planned search terms related to the title of this study. Review and original articles were retrieved, downloaded and saved on a computer. And then the effects of different factors i.e. xenobiotics, age, sex and lifestyle-based practices on the levels of serum Igs (IgG, IgA and IgM) in animals and humans have been studied using a systematic review of different literature sources. Finally, the relationship between the findings of various studies has been assessed and judgment on the possible cause of ageing has been made. Results The findings of different research have demonstrated that the signaling efficiency of immunoglobulin M (IgM) has been limited by the amount of test compounds administered to study Balb c mice in the oral route. The response efficiency of IgM immune response against the lower doses of test compounds were high compared to the higher doses of test compounds which was low. The results of different other studies also demonstrated that the decline of serum IgM levels was associated with ageing. The relationship between alcohol consumption and the concentration of serum Igs was also described in the report of different studies. These studies have shown that there was lower level of IgG in the blood serum of alcohol consumers compared to non-consumers. The study has also demonstrated a lower level of serum IgM with higher alcohol consumption and higher serum concentration with moderate beer consumption. Conclusion The trajectory of Igs’ immune response against different amounts of xenobiotics was highly associated with the trajectory of biological changes during ageing. These research findings might be the possible evidence to conclude that ageing is caused by the foodstuffs and non-foodstuffs we usually consume, the lifestyles we usually experience and the way of life we usually live in the environment which gradually defiling the natural processes of the body.

Background Many older adults remain vulnerable to COVID-19 infections. They are also often at risk for frailty and poor health outcomes. Aim This exploratory review examines the correlates of long COVID and frailty and their association insofar as the older adult’s wellbeing may be jeopardized. Methods and procedures Articles that emerged between January 1 2022 and 2023 in major electronic data bases that addressed the current topic of interest were sought using the key words: Long COVID and Frailty. Those deemed relevant were duly downloaded, analyzed and summarized in narrative form. Results A high proportion of older adults can be expected to remain vulnerable to COVID-19 long term impacts, plus new variants of infection, along with frailty as both an outcome and mediator. Many too are at risk for persistent long COVID-19 complications and a low life quality if more concerted preventive and rehabilitation efforts to avert frailty early on are not forthcoming in a timely manner. Conclusion Prompt and continuing frailty assessments of older adults at risk for COVID-19 or recovering from this disease, especially those with long COVID manifestations who are frail or may become frail are strongly indicated.

Background Osteoarthritis, the most common joint disease and one affecting a large number of older adults is not always amenable to the use of passive interventions such as surgery or pharmacologic interventions, but even then, to maximize any desirable intervention approaches, a trustworthy and supportive partnership with the sufferer is strongly indicated. Complicating this process are emerging equity and persistent health literacy issues, as well as post COVID-19 service associated ramifications and persistent disease risks. Aim This mini review was designed to examine what current data reveal as regards the presentation of osteoarthritis and its pathology among the older adult as of the current post COVID-19 pandemic period in 2022, and how health literacy and equity issues are likely implicated in some degree with the disease presentation and its outcomes and will be likely to continue, unless remediated. Methods Peer reviewed published articles on this topic were sought from multiple data bases using the key words- osteoarthritis, health equity, health literacy, prevention, and intervention. Results As in prior years, osteoarthritis continues to induce considerable physical disability and consistently impedes the attainment of a high life quality for many older adults. Although not studied to any degree, attention to health equity and literacy issues appear to pose additional osteoarthritis intervention challenges, especially among the long COVID affected older adults and those with low income and educational levels. Conclusions Many behaviourally oriented and necessary osteoarthritis management approaches and interventions may fail to reduce the functional disability and pain experienced by older people with any form of osteoarthritis to any meaningful degree if a) the provider does not tailor their recommendations in light of possible prevailing health literacy, economic, and educational challenges; b) the patient does not understand how their health behaviours impact joint disease as well as COVID-19 risk status, and are not empowered to undertake these.

Background Osteoarthritis, a serious joint disease, said to represent a generally declining state of wellbeing and function among many older adults has been shown to be affected to a considerable degree by various negative beliefs and inactions rather than degradation alone. Aim This review examines the case of depression as this pertains to the older adult with osteoarthritis of one or more joints. Specifically, the most up to date information on this topic was sought, as care improvements over the past decade have not shown any impactful population wide results. Method Reviewed were relevant 2021-2022 research and review articles specifically pertaining to what is being observed currently by researchers as far as osteoarthritis-depression linkages goes, as these may reveal opportunities for more profound research, and practice-based endeavors. Results In line with 60 years of prior research, it appears a clinically important role for depression in some osteoarthritis cases cannot be ruled out. It further appears that if detected and addressed early on, many older adults suffering from osteoarthritis may yet be enabled to lead a quality life, rather than a distressing and excessively impaired state of being. Those older osteoarthritis cases requiring surgery who suffer from concomitant depressive symptoms are likely to be disadvantaged in the absence of efforts to treat and identify this psychosocial disease correlate. Conclusion Providers and researchers are encouraged to pursue this line of inquiry and begin to map clinical osteoarthritis measures with those that can track cognitive patterns, musculoskeletal, features and inflammatory reactions along with valid depression indicators among carefully selected osteoarthritis sub groups.

Aim and Objective Despite the growing concerns about the relationship between exposure to radiofrequency radiation (RFR) and detrimental health effects due to the changes in biological processes of experimental animals, there is still ongoing debate on the significance of these findings in causing significant public health problems with the growing advancement in internet technology. The aim of this study is to review existing literature on the effects of high RFR on wistar rats. Method A search was conducted on Google scholar and PubMed to identify relevant peer-reviewed articles to be included into the review. Studies eligible for inclusion included free full text articles on wistar rats exposed to ≥ 2.45GHz RFR conducted in the past 5 years. Studies included in this review were written or transcribed in English language. From 286 titles, 36 eligible studies were included in the review and assessed for quality using the Strengthening the Report of Observational Studies in Epidemiology – Veterinary Extension (STROBE-Vet) quality assessment tool. Results Studies included in this review generally had good quality (>60%) based on the STROBE-Vet assessment. This review identified numerous biological changes in wistar rats exposed to high RFR including variations in biochemical, cholinergic, genetic, histopathologic, psychological, optical, and dermatological parameters. In this review, studies identified variations in protein and liver enzymes while high RFR was found to induce oxidative stress and cellular damage of exposed wistar rats compared to the unexposed groups. This was seen in the changes in protein, lipids, enzymatic and non-enzymatic antioxidants. Studies also identified changes in expression of genes and neurotransmitters with imbalance in hormones. In addition, this review identified structural changes of cells, tissues and organs indicative of apoptosis, damage and death. Exposed rats were identified to have behavioral changes indicative of anxiety and memory decline while studies identified optical and dermatologic changes in exposed rats compared to the unexposed. Conclusion With numerous biological changes identified in wistar rats exposed to high RFR, there is an increasing risk of detrimental health events giving the advancement in internet technology and limited regulations to control exposures to RFR. Therefore, studies should be conducted to identify strategies to mitigate human exposure to RFR while policies are developed and enforced to protect human health.

Background The origin of osteoarthritis, the most common disabling disorder of older adults remains uncertain. Aim This mini review examines the possible role played by various neuromuscular deficits in the osteoarthritis etiopathogenic process. Methods and Procedures Articles that haveaddressed the current topic of interest and were located in the PUBMED,Google Scholar, and Web of Science electronic data bases as of 2017-2022 were carefully sought and examined. Results Various neuromuscular mechanisms may have a bearing on the development and progression of osteoarthritis, but the data are largely unrelated and observational in nature. Conclusion More research to examine this issue is sorely needed and could have considerable merit in light of the growing populations of older adults at risk for disabling osteoarthritis in the face of few intervention options to help them to achieve an optimal functional level.

Background The pandemic has disrupted the lives of many globally including persons with disabilities. These disruptions are universal. However, the vulnerable communities are more affected. Purpose The study examines impacts on persons with disabilities to share knowledge and inform interventions that ensure persons with disabilities are supported. Methodology The study is a systematic literature review using different search engines to search for scholarly articles all over the globe. Results Persons with disabilities have been negatively impacted in numerous ways: lack of access to healthcare services, inadequate rehabilitation services, increased human rights violation, stigmatization and discrimination, increased risk of dying, being subjected to violence, losing financial income, lack of access to education and treatment, increased in neglect and traumatization, poverty, lack of access to food, decreased in community support; and worse of all, in comparison with the overall population, the death of persons with disabilities during the Covid-19 is higher. These impacts were precipitated by inaccessible built environment and sense of touching, lack of disability sensitive policies, increased prevalence of risk factors, difficulties in adhering to WHO recommendations, pervasiveness of underlying health conditions, lack of disability-friendly information and inclusive intervention, national budget cuts; and poorly funded institutions. Conclusion Persons with disabilities have been negatively impacted due to many risk factors peculiar to them.

Background Many older adults, including those who have acquired painful disabling osteoarthritis of one or more joints may be frail rather than obese as is often reported. Those older adults who are frail may acquire osteoarthritis in turn if they encounter excess joint stresses and injury. Aims This report sought to examine what has been published to date on both of these debilitating health states, namely osteoarthritis and frailty. Methods Reviewed were relevant articles published in ACADEMIC SEARCH COMPLETE, PUBMED, WEB OF SCIENCE, SCOPUS and GOOGLE SCHOLAR regardless of time period but that focused on osteoarthritis and frailty related topics. The focus was on ascertaining how these two conditions might interact among community-dwelling older adults and whether more should be done specifically to mitigate any potentially preventable ‘frailty’ induced negative health impact among this group. Results Older adults with osteoarthritis living in the community may suffer from both osteoarthritis and frailty. Those that do are at high risk for disability and injury and should be targeted more effectively. Conclusion Timely and concerted efforts are needed to offset frailty correlates as well as excess osteoarthritis disability among community dwelling older adults.

Background Many older adults are vulnerable to becoming frail. They are also often at risk for falling and serious injuries and poor health outcomes. Aim This exploratory review examines the correlates of frailty, and fear of falling and their association insofar as older adults wellbeing may be jeopardized. Methods and Procedures Articles extracted from major electronic data bases that addressed the current topic of interest were used. Key findings regarding the syndromes of frailty and fear of falling were duly downloaded, analyzed and summarized in narrative form. Results A high proportion of older adults can be expected to exhibit frailty or become frail as they age. Many too are at risk for falls and fear of future falls, regardless of frailty status. A persistent fear of falls may however, heighten frailty risk or manifestations if not duly addressed in a timely manner. Conclusion Prompt comprehensive assessment of at risk older adults, as well as the frail and pre frail older adult, plus those who have fallen may avert serious injury and long term disability plus excess frailty and its deleterious impacts this syndrome has on aging older adults as well as societies.

Background Aging, a state often associated with poor emotional health status greatly impedes life quality and independence for many. Aim This mini review examines the potential of the concept of positive psychology as an active approach to fostering successful or more successful, rather than suboptimal aging. Methods and Procedures Articles that addressed the current topic of interest and were located in the PUBMED, Medline, Web of Science, PsycINFO and Google Scholar electronic data bases were carefully sought and analyzed and presented in narrative form. Results Various forms of positive psychology appear to provide a safe efficacious evidence based approach for purposes of ameliorating various degrees of anxiety and depression and for improving cognition, life quality, and health well-being in diverse subgroups of older adults Conclusion More research to examine who might benefit most from this highly promising form of intervention, and in what respect appears to have considerable merit in light of the growing populations of older adults and few intervention options to help them to age optimally and as successfully as possible.

Background Anxiety and depression are key barriers to healthy aging and greatly heighten the risk for many negative health issues that seriously impact life quality. Aim This mini review examines the potential of low level laser treatments or photobiomodulation therapy for ameliorating severe anxiety and depression in older adults. Methods and Procedures Articles that adressed the current topic of interest extracted from PUBMED and Google Scholar were carefully and presented in narrative form. Results Photobiomodulation therapy appears to be a safe efficacious modality for ameliorating various degrees of anxiety and depression and for improving cognition, and is supported by several well established mechanisms of action at the molecular, cellular, and tissue levels. Conclusion More research to examine who might benefit most from this form of therapy, and in what respect in this area of growing global concern and few intervention options is strongly warranted.

Phenomenology is a ritual of Qualitative research methodology. Interviews in healthcare enables researchers to recognise and understand data from lived experiences of the participants by using Phenomenological approach. The purpose of this article is to review the various face to face in depth interviews conducted using Husserl’s descriptive, Heidegger’s interpretive phenomenology or Hermeneutic phenomenological approach in healthcare. The in-depth interview will help to understand the health issues and ethical issues faced by participants. Methodology Four articles were selected based on phenomenological approach. Article.1 was based on Hermeneutic Phenomenology approach. In this study thirteen women were taken as sample. Sampling was done by snowball method. The women were asked to share their rural maternity experience. Data was analyzed without any influence of the researcher. Article.2 was based on Transcendental phenomenology. There were 15 students from 4 different cultural background belonging to different health professional programmes like nursing, medicine, pharmacy, dentistry, and physical therapy. Triangulation methods were used and semi structured interviews were conducted, recorded and transcribed. Health professional students shared their lived experience with patients. Article.3 was based on a study conducted using both Transcendental phenomenology for patients interviews and Hermeneutic phenomenology for healthcare professionals’ interviews. The semi structured interview of patient was taken to understand and record their lived experience with the medication without any bias or interpretation and data received was bracketed. The healthcare professionals’ interviews were conducted on Hermeneutic strategy regarding the medications they prescribe for life threatening illnesses. Article 4 was based on Hermeneutic phenomenological approach. There were nine patients selected and in depth semi-structured interviews were conducted. The patients shared their experience of living with a life limiting illness.

Background Aging is said to represent a declining state that is possibly especially compromised by sleep issues, and declining melatonin levels. Aim This review examined the idea that aging can be favorably influenced in numerous ways by the addition or maintenance of adequate melatonin levels. Specifically, the impact of melatonin on skeletal muscle was the key topic of interest. Method Reviewed were peer reviewed research and review articles specifically pertaining to healthy aging, melatonin, and muscle associated observations. Results Declining melatonin levels greatly impact multiple essential body systems and tissues. Supplements or interventions that heighten melatonin presence appear to have beneficial impacts on aging in general, and muscle function and structure, in particular. Conclusion The use of melatonin early on in the aging process is likely to produce more favorable long-term outcomes than not in cases of deficiency, and should be further investigated.

Background Aging, a commonly accepted time period of declining heath has been shown to vary in terms of its impact on function and independence. Aims This mini review examines the current impact of COVID-19 on the goal of ‘successful aging’, a conceptual model and outcome variable deemed desirable, but hard to attain. Methods Peer reviewed articles published between March 1 2020 and April 15 2021 focusing on ‘successful aging’ and COVID-19 secondary impacts, as located in the PUBMED data base were specifically sought. Results Despite a lack of consensus on the concept of ‘successful aging, and whether this can be achieved or not, ample evidence points to a severe secondary impact on efforts to age as successfully as possible by older adults, especially those isolated in the community as a result of lockdowns. Conclusion Pursuing more efforts to counter predictable harmful cognitive as well as physical impacts of lockdowns, resource and movement restrictions is urgently needed.

Ascorbic acid is a water-soluble vitamin (Vitamin C) essential for both the plants and animals for the metabolic process. In this study, the liquid chromatography-mass spectrometry (LC-MS) analytical technique was used to characterize the structural properties and isotopic abundance ratio to evaluate the effect of the Trivedi Effect®-Consciousness Energy Healing Treatment on L-ascorbic acid compared to the control sample. The ascorbic acid sample was divided into control and treated parts. Only the treated part received the Trivedi Effect®-Consciousness Energy Healing Treatment remotely by a well-known Biofield Energy Healer, Mahendra Kumar Trivedi. The control and treated samples showed a chromatographic peak at retention time (Rt) 1.8 minutes exhibited the deprotonated molecular ion peak at m/z 175 (M-H)- (calculated for C6H7O6-, 175.02) in the mass spectra. The peak area of the treated sample (12817614.01) was significantly increased by 8.81% compared to the control sample (11779918.9). The LC-MS based isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 17O/16O) in the treated ascorbic acid was significantly increased by 23.22% compared with the control sample. Thus,13C, 2H, and17O contributions from (C6H7O6)- to m/z 176 in the treated ascorbic acid were significantly increased compared with the control sample. The increased isotopic composition of the treated ascorbic acid might have altered the neutron to proton ratio in the nucleus. The changes in isotopic abundance could be due to changes in nuclei possibly through the interference of neutrino particles via the Trivedi Effect®-Consciousness Energy Healing Treatment. The increased isotopic abundance ratio and peak area of the treated ascorbic acid may increase the intra-atomic bond strength and its stability. This novel ascorbic acid after the Trivedi Effect®-Consciousness Energy Healing Treatment would be very useful to design more efficacious pharmaceutical formulations against scurvy, obesity, cardiovascular diseases, hypertension, rheumatoid arthritis, Alzheimer's disease, cancer, etc.

L-tryptophan is an essential α-amino acid, necessary for the normal growth in newborns, nitrogen balance in adults, protein synthesis, precursor of serotonin, melatonin, niacin, and albeit inefficiently in human, also the precursor of indole alkaloids and auxins in plants. This current study was designed to investigate the impact of the Trivedi Effect®-Biofield Energy Healing Treatment (Blessing) on the structural properties and the isotopic abundance ratio of L-tryptophan using LC-MS analytical technique. L-tryptophan sample was divided into two parts, one part of L-tryptophan was considered as the control sample (no Biofield Energy Treatment was provided), while the second part was treated with the Trivedi Effect®-Consciousness Energy Healing Treatment/Blessing remotely by a renowned Biofield Energy Healer, Dahryn Trivedi and termed as the treated sample. The mass spectra of both the control and treated samples with respect to the chromatographic peak at retention time (Rt) 2.1 minutes exhibited the mass of the molecular ion peak adduct with hydrogen ion at m/z 205.08 (calcd for C11H13N2O2+, 205.1), along with low molecular fragmented mass peaks at m/z 188, 159, and 102 for C11H12N2O2+, C10H11N2+, and C8H6+, respectively were also observed. The isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 15N/14Nor17O/16O) in the treated L-tryptophan was significantly increased by 35.93% compared with the control sample. Hence,the 13C, 2H, 15N, and 17O contributions from C11H13N2O2+ to m/z 206.08 in the treated L-tryptophan was significantly increased compared to the control sample. It could be hypothesized that the changes in the isotopic abundance and mass peak intensities due to the modification in nuclei possibly through the interference of neutrino particles using the Trivedi Effect®-Consciousness Energy Healing Treatment. The Biofield Energy Treated/Blessed L-tryptophan with increased stable isotopic abundance ratio might have changed the physicochemical properties with higher force constant in the molecule. The new form of treated L-tryptophan would be a better and more stable in the supplements, nutraceutical, and pharmaceutical formulations, which would be advantageous for the prevention and treatment of pellagra, depression, kynurenine. It could also maintain the normal label of tryptophan and avoid increase of its metabolite, lower the neurotoxin and a metabotoxin behavior, glutaric aciduria type I (glutaric acidemia type I) disorder, eosinophilia-myalgia syndrome (EMS), incurable and sometimes fatal flu-like neurological condition, etc. As tryptophan is the precursor for the plant hormones like indole alkaloids and auxins, hence, this treated L-tryptophan would be advantageous for the improvement of yield, productivity, and quality of crops and other plants.

In the catering industrytobacco smoke was the primary source of fine and ultrafine particles, which are well known for their health-damaging effects. As shown in studies, attempts to reduce passive smoking in the catering industry of Vienna, like separated smoking rooms, failed to reduce fine and ultrafine particle concentrations effectively. On November 1st 2019, an enlarged non-smoker’s protection law was introduced, including a total smoking-ban in the catering industry. 40 hospitality venues with areas for smokers and non-smokers before the ban had been selected as typical Viennese cafes, pubs, bars and discotheques to be sampled unannounced. Concentrations of fine particle mass (PM10, PM2.5, PM1) and ultrafine particle number (PNC) and lung deposited surface area (LDSA) could be measured before and after the introduction of the smoking-ban in 39 venues at nearly identical locations and under comparable circumstances. Results showed a statistically significant decline in both fine and ultrafine particle concentrations in the former smoking areas for all parameters as well as in the former non-smoking areas for PM2.5, PM1 and LDSA. After the ban concentrations in former smoking areas and non-smoking areas showed no significant differences any more. From these results the smoking-ban successfully removed particles from breathing air of guests and staff, however, some outliers in the study after the ban point to the necessity of repeated controls in Vienna. Also, outside Vienna the compliance with the law should be controlled in the Austrian hospitality industry.

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.

Background Older adults with hip joint osteoarthritis, a major cause of chronic progressively disabling highly painful functional experiences, may require a surgical joint replacement procedure known as total joint arthroplasty surgery. Objective This review aimed to address the question of whether there an association between hip joint arthroplasty infection rates and prevailing pre or preoperative vitamin D levels that warrants consideration in efforts to prevent or minimize infection related hip arthroplasty complications among older adults particularly during the current ongoing COVID-19 pandemic. Methods PUBMED, SCOPUS, and WEB OF SCIENCE articles related to the topic and published between January 2016-2021 were searched, examined, and summarized. Results Older adults with hip joint osteoarthritis and low vitamin D serum levels who undergo total hip joint arthroplasty surgery may be at higher risk for post-operative infections than those with adequate vitamin D serum levels. Conclusion More research to verify whether efforts to screen for, and maximize vitamin D levels, before and after surgery, as indicated, may be helpful in the context of minimizing total hip joint arthroplasty surgery infection susceptibility and severity among older vitamin D deficient severely disabled hip osteoarthritis cases.

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.

The prostate gland is subject to various disorders. The etiology and pathogenesis of these diseases remain not well understood. Moreover, despite technological advancements, the differential diagnosis of prostate disorders has become progressively more complex and controversial. It was suggested that the antimony (Sb) level in prostatic tissue plays an important role in prostatic carcinogenesis and its measurement may be useful as a cancer biomarker. These suggestions promoted more detailed studies of the Sb content in the prostatic tissue of healthy subjects. The present study evaluated by systematic analysis the published data for Sb content analyzed in prostatic tissue of “normal” glands. This evaluation reviewed 1998 studies, all of which were published in the years from 1921 to 2020 and were located by searching the databases PubMed, Scopus, ELSEVIER-EMBASE, Cochrane Library, and the Web of Science. The articles were analyzed and “Median of Means” and “Range of Means” were used to examine heterogeneity of the measured Sb content in prostates of apparently healthy men. The objective analysis was performed on data from the 23 studies, which included 1173 subjects. It was found that the range of means of prostatic Sb content reported in the literature for “normal” gland varies widely from 0.0066 mg/kg to 0.071 mg/kg with median of means 0.0085 mg/kg on a wet mass basis. Because of small sample size and high data heterogeneity, we recommend other primary studies be performed.

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.

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.

Metronidazole is an antibiotic and useful for the antibacterial and antiprotozoal medication. This study was performed to investigate the impact of the Trivedi Effect®-Biofield Energy Healing Treatment on the structural properties and the isotopic abundance ratio of metronidazole using LC-MS and GC-MS spectroscopy. Metronidazole sample was divided into two parts, one part of metronidazole was considered as control (no Biofield Energy Treatment was provided), while the second part was treated with the Trivedi Effect®-Consciousness Energy Healing Treatment remotely by a renowned Biofield Energy Healer, Alice Branton and termed as a treated sample. The LC-MS spectra of both the samples of metronidazole at the retention time (Rt) 2.61 minutes exhibited the mass of the protonated molecular ion peak at m/z 172 M+H+ (calculated for C6H10N3O3+, 172.07). The LC-MS based isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 15N/214N or 17O/16O) in the treated metronidazole was significantly increased by 8.24% compared with the control sample. Thus,13C, 2H, 15N,and17O contributions from (C6H10N3O3)+ to m/z 173 in the treated sample were significantly increased compared with the control sample. The GC-MS based isotopic abundance ratio of PM+1/PM in the treated metronidazole was significantly increased by 5.92% compared with the control sample. Hence,13C, 2H, 15N, and217O contributions from (C6H9N3O3)+ to m/z 172 in the Biofield Energy Treated sample were significantly increased compared with the control sample. However, the isotopic abundance ratio of PM+2/PM in the treated metronidazole was significantly decreased by 18.2% compared with the control sample. Hence,18O contributions from (C6H9N3O3)+ to m/z 173 in the treated sample were significantly decreased compared with the control sample. The isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 15N/14N or 17O/16O) and PM+2/PM (18O/16O) in the treated metronidazole was significantly altered compared to the control sample. From the results, it can be hypothesized that the changes in isotopic abundance and mass peak intensities could be due to changes in nuclei possibly through the interference of neutrino particles via the Trivedi Effect® - Consciousness Energy Healing Treatment. The new form of treated metronidazole would be better designing novel pharmaceutical formulations that might offer better therapeutic response against bacterial and protozoal infection in the vagina (bacterial vaginosis), stomach (giardiasis, trichomoniasis, pseudomembranous colitis), joints (pelvic inflammatory disease), liver, skin, brain, and respiratory tract, aspiration pneumonia, rosacea, intra-abdominal infections, lung abscess, fungating wounds, periodontitis, amoebiasis, oral infections, etc.

The composites of Cu, Carbonyl iron (CI), carbon nanofiber (CNF), graphite nanoflake (GNF)/polypyrrole (PPy) and [(Cu-CI-CNF-GNF) 0.5-PAA]-PPy0.5 were synthesized via different methods by in-situ polymerization on the surface of nanoparticles (NPs) with core-shell structure. This paper describes a method for polyacrylic acid (PAA) coating of NPs in aqueous solution. Then PPy coating was performed by template polymerization on NPs-PAA. Morphology, magnetic and conductivity properties were observed via scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and four probe method, respectively. The microwave characterization of nanocomposite was evaluated through arch test based on a network analyzer. The PPy nanocomposites possessed the excellent microwave multi absorbers properties in 2-18 GHz. It was also found that nanocomposites with 50% w/w and light weight exhibit good microwave absorbing properties in 2-3 GHz and 5-14 GHz frequency, so can be used to cellphone, radio frequency and radar shielding.

The purpose of this scoping review was to examine the use of Photovoice in caring research. The review assessed the existing literature using the Arksey and O’Malley scoping review methodology. Database searches of relevant literature published worldwide between 1997–2019 yielded 25 articles in the English language that were included in this review. The authors summarized thematic findings. Three themes emerged from data analysis: 1) strengths of using Photovoice; 2) challenges of using Photovoice, and; 3) methodological complexities in Photovoice studies. The small number of studies included in the review (n=25) indicate the limited use of Photovoice in caring research, reflecting missed opportunities for action-oriented research. The scoping review recommends ways that researchers can better address the needs of carers using Photovoice, particularly as a tool for knowledge translation, advocacy, and empowerment.

Hip fractures, which remain highly prevalent among the elderly and produce enormous social and economic costs, have not truly abated in prevalence despite years of research that outlines a multitude of preventable risk factors and intervention programs. This review aimed to examine if sleep disturbances have a bearing on the risk of incurring a hip fracture directly or indirectly, among older adults. The specific aim was to explore and summarize what we know, and how this might inform future research and practice. To this end, PUBMED, Web of Science, Scopus, and Google Scholar data bases were searched to uncover available data representing the topic of sleep in relation to hip fractures among the elderly. Articles of note were scrutinized and summarized in narrative form. Results showed very few studies on the topic prevail, even with no restriction on years examined, and of these, discordant, rather than any solid uniform conclusions prevail. It is concluded there is a need to explore this topic carefully, including both the direct, as well as the indirect impact of sleep that may place an older adult at heightened risk for a fall and hip fracture injury as well as subsequent fractures.

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.

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.

Waldenström Macroglobulinemia (WM) is a B-cell lymphoproliferative disorder characterized mainly by uncontrolled accrual of M- immunoglobulin, secreted by malignant lymphoplasmatic cells. Mast cells interacting with malignant B-cells play an important role at the manifestation of the disease. Utilizing a previous xenotransplantation mouse model, this study evaluates long-term implant viability and quantifies distinct bone marrow mast cell populations along with their dynamics in non-WM and WM human bone implants. Non-WM bone implants were obtained from the femoral head of adult humans undergoing hip arthroplasty or hemiarthroplasty, whereas WM human bone implants originated from bone biopsies obtained from the posterior iliac crest of patients with active WM. All bone particles were implanted intramuscularly in twenty-four NOD/SCID mice. Following 3, 4 or 8 months postoperatively, xenografts were removed and studied using special histological techniques to identify mature and immature mast cells. Xenografts survived up to 8 months after implantation presenting normal cytoarchitecture (non-WM) or high-grade neoplastic infiltration and microresorption (WM bone biopsies). Statistical analysis of mast cell populations showed significant elevation regarding time progression and bone marrow microenvironment, thus suggesting the possible influence of malignant cells to the mast cell population in WM. This study presents the extended survival of intramuscular implantation of human adult bone xenografts into NOD/SCID mice and provides additional information on the interaction between mast cells and malignant B-cells.

Background The objective of this review is to unify the various genetic defects along with elaborating metabolic pathways in Familial Combined Hyperlipidemia(FCHL) and also to differentiate the phenotype of FCHL from metabolic syndrome. Methods PubMed and Cochrane’s library was searched for keyword “Familial combined hyperlipidemia” and latter with “Familial combined hyperlipidemia genes” to finally shortlist 23 articles. Further search with key words “molecular pathogenesis of familial combined hyperlipidemia” and “metabolic syndrome and familial combined hyperlipidemia” was carried out for finding molecular defects in FCHL, non-molecular findings distinguishing FCHL from metabolic syndrome and overlapping features between FCHL and metabolic syndrome. Results Major culprit regions identified included Chromosome-1q21-q24(USF1 and FOXA2) , Ch-11q (APOA5), Ch-16q24, Ch-20q12-q13.1, Ch.4q32.3 (rs6829588), and Ch-19q13.32 containing PVRL-2 gene (Also known as Nectin-2). The genetic and metabolic pathways linked to FCHL may involve: 1-Defective clearance of Apo-B containing lipoproteins, 2-Overproduction of Apo-B containing lipoprotein i.e., VLDL and 3-Adipose tissue dysfunction. FCHL phenotype showed close resemblance with metabolic syndrome clinical and biochemical features with slight differences. Conclusion The reviewed data suggested that FCHL phenotype is the resultant end outcome from multiple molecular defects and thus underlying genetic defect identification in the index case is important for personalized medicine and incoming gene therapy. Further research is warranted to explore specific genetic defects.

Objectives Death is the only definitive phenomenon in life, and everyone is sure that it will happen in the future. Based on the philosophical perspective, the concept of death differs in different cultures. The purpose of this study was “explaining the difference between the concept of death from the perspective of theology and empirical science”. Methods In this qualitative evolutionary study, a targeted review was conducted to answer the question “what is the difference between the concept of death from the perspective of theology and empirical science?” Articles published between 1990 and 2018 were extracted from the PubMed, science direct, google scholar, SID, and Cochrane databases. At the same time, Islamic religious evidence (Quran and Hadiths) was investigated for understanding the concept of the death in Islam. The “Shia Seminary” research methodology was used to avoid interpretations of the Quran verses and to ensure the authenticity of the Hadiths. Findings Empirical sciences consider death as a biological phenomenon, which results from irreversible damage to cerebral hemispheres and brain stem (brain death) that causes grief process, fear, anxiety, and sadness. From the perspective of Islam, death is an existential phenomenon, the transfer of the soul from one world to another. Death is the complete reception of the soul from the body by the angels and the beginning of another life, in the "world of grief. Conclusion Given that in Islam, death does not mean destruction. It is imperative that the spiritual counselors teach the patient and the family about the life after death and the blessings of paradise. In pastoral care at the end of life, reducing patients’ anxiety and fear of death, with hope in God's mercy is necessary.

Advances in nanotechnology especially in nanofluids comprising of a typical base fluid saturated with nano-size metallic particles with enhanced thermophysical properties is one of the hot topics in industrial as well as engineering applications of applied mathematics. This article explores the impact of Lorentz forces and Maragoni effect on second grade nanofluid forced convective flow. A two phase model is chosen to validate the nanofluid. Series solutions are achieved through HAM after transformation of PDEs into ODEs. The Brownian motion effect, Thermophoresis and the Marangoni effect are the main influencing factors for present flow model. In addition, the influence of pertinent fluid parameters such as Schmidt number, Magnetic number and Prandtl number on the velocity, temperature and concentration profiles is discussed with the help of graphs. With an enhanced Marangoni factor the hydraulic boundary layer thickness shows enhancement.

This study aims to numerically investigate the Marangoni convective flow of nanoliquid initiated by surface tension and heading towards a radiative Riga surface. The surface tension appears in the problem due to the gradients of temperature and concentration at the interface. The influence of first order chemical reaction is involved in the system with sufficient boundary conditions. Set of governing nonlinear PDEs is transformed into highly nonlinear ODEs using suitable transformations. HAM is applied for convergent series solutions. Impact of various pertinent fluid parameters on momentum, thermal and solutal boundary layers is analyzed graphically. The chemical reaction plays vital role in saturation of nanoparticles in the base fluid near the surface as well as away from it. The Lorentz forces originated by the Riga surface become powerful when the radiation parameter comes into effect. The significance of Riga plate is thus more prominent through thermal radiation. However, the magnetic effect dampens down for higher radiation parameter. Fluid parameters, Nusslt and Sherwood numbers are analyzed with detailed discussion and concluding remarks.

Self-determination is a key concept to promote greater self-awareness in the subjects with disability, to build appropriate educational or professional projects and to evaluate the already active programs. Using PRISMA checklist, I selected articles from different databases (CINAHL, Medline, Psych INFO, Cochrane Library, ERIC, Scholar. The 9 evaluation measures identified are analyzed with respect to: choice of the points of view to be collected, domains, items and data collection methods. The results show that while some scales focus on autonomy, empowerment, self-realisation and self-regulation and others focus on knowledge, skills and abilities, attitudes and beliefs. Two instruments added also: opportunities and support. With respect to the choice of the points of view to be collected: in some cases the student’s opinion is collected but in other cases their point of view is integrated or replaced with that of teachers and parents. Only one tool is designed for all children and starts from the belief that self-determination is important for all people, including those with a disability. A third element of the analysis is the possibility of answering the questions posed by the various evaluation tools. A typical form is Likert scale while in other cases open questions are used. The analysis highlights two critical issues. The variety of definitions of self-determination is inevitably reflected in the choice of domains and items and therefore self-determination is only partially investigated. Secondly the opinion and people with disabilities are sometimes completed or replaced by that of third persons as parents and teachers. Starting from the analysis of existing instruments. the article closes with a reflection on the possibility of constructing a scale that considers all the aspects of self-determination offered in the literature (at the individual and environmental level) and collects the opinion of all the subjects involved in self-determination projects. This synthesis represents a first step in the construction of a possible universal scale starting from the analysis of the literature. A comparison would then be necessary with the students with intellectual disabilities, the family members and the other actors involved to understand which domains are really meaningful to them and to build indicators that correspond to the elements that are important to them. In this way we would have a tool capable of combining the point of view of literature with that of the people directly involved.

Over the decades there have been problems associated with Particulate Matter (PM) arising from anthropogenic activities. Evaluation and health risk assessment of PM associated with football field was carried out in 5 sampling locations, including the control station. Digital portable AEROCET 513 (Metone instrument) PM meter was used for the evaluation Results showed levels of PM for; PM1.0(13.73 – 20.18 µg/m3), PM2.5 (19.11 – 28.83 µg/m3), PM4.0 (24.73 – 44.63 µg/m3), PM7.0 (41.07 – 67.04 µg/m3), and PM10 ranging from 65.48 – 90.82 µg/m3. In addition, value of the control station was lowest amongst all recorded values of PM (p<0.05). Based on Air Quality Index evaluation, the football fields were predominantly rated as unhealthy, with other cases rates as; hazardous and unsafe for sensitive group. This investigation therefore concludes that the emission of PM from the football field are reflection of vehicular emissions and agitated dust particles. Hence mitigable measure must be applied without much ado, in order to ameliorate the daily chronic exposure to PM.

Background Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are categorized as omega-3 poly unsaturated fatty acids (PUFAs) that are present in fish oil, etc. DHA and EPA omega-3 PUFAs have a well-established fasting serum triglycerides (TG) lowering effect that may result in normal lipidemia in hyperlipidemic patients. In general, omega-3 PUFAs, such as DHA and EPA, can be ingested easily, and because they are highly safe, they are assumed to be suitable for controlling fasting serum TG in the serum of those who do not require drug treatment. To the best of our knowledge, however, almost all systematic reviews on the effects of omega-3 PUFAs on lowering fasting serum TG are directed at patients fulfilling the diagnostic criteria of dyslipidemia. Objectives To review and confirm the preventive effect of omega-3 PUFAs against hypertriglyceridemia or the effect on nondrug treatment in patients with a mild disease, a systematic review was conducted to determine whether there was a fasting serum TG-lowering effect in subjects without disease and those with a slightly higher triglyceride level who consumed DHA and/or EPA orally compared to those with placebo or no intake of DHA and/or EPA. Search Methods We evaluated articles from searches of PubMed (1946-February 2016), Ichushi-Web (1977-February 2016), and J Dream III (JST Plus, 1981-February 2016; JMED Plus, 1981-February 2016). The keywords were set as follows: “DHA” or “docosahexaenoic acid” or “EPA” or “eicosapentaenoic acid” and “TG” or “triglyceride” or “triglycerol” or “triacylglycerol” or “neutral lipid.”. In addition to the literature group obtained by the database search, we included participants not suffering from any disease (i.e., excluding mild hypertriglyceridemia). Eligibility Criteria Before the test selection process, the following inclusion criteria were defined. Participants were healthy men and women including those with mild hypertriglyceridemia (fasting serum TG level, 150-199 mg/dL [1.69-2.25 mmol/L)). Intervention was defined as orally ingested DHA and/or EPA. Comparison was made to placebo intake or no intake of DHA and/or EPA. Results were measured for the fasting serum TG level. The test design was RCT, and quasi-RCT. Data Abstraction Various characteristics were extracted from original reports using a standardized data extraction form, including the author of the study, research year, research design, subject characteristics (sex, age, sample size), period, dose of DHA and/or EPA (mg/day), and comparison group. Main Results We identified 37 documents for review. Among the 37 reports used to integrate literature results, 25 revealed a decrease in fasting serum TG level due to the oral ingestion of DHA and/or EPA. Sixteen studies on subjects without disease and 21 on subjects with slightly higher fasting serum TG levels were separated and stratified analysis was conducted. Ten of the 16 (normal TG participant) and 15 of the 21 studies (slightly higher TG participant) respectively, indicated that at least 133 mg/day of DHA and/or EPA intervention provided a statistically significant decrease in the fasting serum TG level between an intervention group versus a placebo group.

This study was devoted to the learning of the use of nanotechnology to correct the functional activity of red blood cells (RBCs) at the storage stages at a positive temperature. It was established that saline NaCl, which had previously been processed by magnetite nanoparticles (ICNB) had a marked membrane-stabilizing effect, inhibits hemolysis and increasing the sedimentation stability of preserved RBCs. The complex analysis of the obtained data allowed to determine the primary mechanisms effect of the saline NaCl, which had previously been processed by ICNB on the preserved RBCs. The proposed method of additive modernization of preserved RBCs was adapted to the production process. The optimization results were obtained in creating a simple and practical method of additive modernization of preservation solutions that does not violate the compliance requirements, improves the quality, efficiency and safety transfusion of RBCs.

MicroRNAs are short sequences of non-coding RNAs crucial in regulation of cell development, proliferation and differentiation. Some of them showed to be related with the expression of osteogenic genes. Aim of the present review was to evaluate the biological effects of titanium implant surfaces activated with miRNAs or antimiRNAs. A bibliographical electronic research was carried out on PubMed/Medline. Articles investigating the influences of miRNA functionalized surfaces on human or animal cells were included. Reports were excluded if investigating surfaces modified with molecules different from miRNAs, if miRNAs were not loaded to titanium surfaces. Five articles met the inclusion criteria. Surfaces functionalized with miRNAs showed to up-regulate the expression of osteogenic genes like RUNX2, OPN, OCN, BMP, OSX, ALP, COL1 and COL3. Investigated surfaces additionally showed more bone-like mineralized tissues, bone lacunae, osteocytes and new blood vessels. MiRNAs loaded to titanium implant surfaces stimulate the expression of genes related to osteoblasts differentiation, osteogenesis, osseointegration and reparation of mineralized tissues. Vectors used to link titanium surfaces and miRNAs did not show cytotoxicity or interference with cells’ viability.

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.

Study Objectives: Narcolepsy diagnosis has been associated with a long lag time between the onset of the disorder and the diagnosis itself among patients with the disorder. This article reviews the childhood epidemiology of idiopathic narcolepsy, including its prevalence, subtypes, and disease progression. Methods: A literature review was conducted to include both published and unpublished data on pediatric narcolepsy. All English language articles were included through April, 2015. Results: Time from symptom onset to diagnosis for children is approximately three years. The prevalence of cataplexy appears to be lower in children compared to adults, suggesting a later onset of cataplexy. The presence of cataplexy, however, was unrelated to demographic factors and laboratory findings. Conclusion: There is a substantial lag-time between initial symptom presentation and diagnosis in children with narcolepsy. A less quintessential presentation of narcolepsy might occur in children relative to adults, making diagnosis more challenging. Continued improvements in narcolepsy education for both pediatricians and parents might facilitate earlier identification and diagnosis of the disease, thus leading to improved outcome.

The global popularity of soccer has led to widespread tendency towards this sport. Because of the convenience of using artificial surfaces, the rapid growth of using these surfaces led to concerns about the declining performance of the players. The aim of this comprehensive review is to study the difference between the performance of players on different playing surfaces and the risk factors for use of artificial turf compared to natural grass. A literature search of valid scientific databases such as Science Direct, PubMed and Jstor by searching keywords was performed. In total, more than 6,000 articles were retrieved. After the preliminary selection process, the final analysis was performed on a total of 76 articles. Results: Mechanical properties of artificial grass have a significant effect on the average time of sprinting, the best time of sprinting and maximum speed. The numbers of sliding tackles on artificial turf were lower compared to natural grass. Artificial turfs exposed hardness, elasticity and high friction. The characteristics of artificial grass have changed over time and increased the probability of injuries. There was no significant difference between the overall risks of acute injuries in soccer players performing on artificial turf compared to natural grass. The amateur, young and female soccer players had rated lower injuries on artificial grass. But the rate of injuries in elite soccer players were higher on artificial grass and hence they are not found of playing on such playing surfaces.

Background: High number of patients suffering from autism spectrum disorders utilize dietary intervention methods, especially gluten-free/casein-free diet. In contrast with its’ extensive usage no sufficient and consistent data exist to support its’ efficiency and safety. Objective: The main aim of this systematic review is to provide a general look to the efficiency and safety of gluten-free/casein-free diet treatment for autism spectrum disorders. Method: Studies used in this systematic review are gathered from 3 online databases (PubMed, Embase and the Cochrane Library). Inclusion criteria are established for study selection. Articles published in a peer-reviewed article between 1990 and 2016 in English about our topic of interest and conducted with patients under the age of eighteen (18) are selected and further analyzed (“Level of Evidence” and “Grade of Recommendation” criteria are utilized). Results: Even though some studies with high values of “Level of Evidence” claim that gluten-free/casein-free diet is beneficial for patients suffering from autism spectrum disorders, studies with lower risk of bias demonstrate otherwise. Since studies such as case reports and cohort studies may contain bias associated with small sample size, absence of clear assessment methods, lack of randomization and short treatment period we suggest that there is no sufficient data to support gluten-free/casein-free diet treatment. Conclusion: Due to controversial outcomes from studies that have different “Level of Evidence” we speculate that efficiency of gluten-free/casein-free diet might be related to individual genetic differences. Therefore, studies conducted with large study groups could not provide statistically significant data to support this treatment option. Further studies should be conducted, especially in the field of genetics, in order to test our hypothesis.

This essay draws on recent evidences from SIV vaccination studies in rhesus macaques to argue for the potential importance of HIV-1-specific CD8+ T cells restricted by the non-classical major histocompatibility complex, HLA-E, in controlling HIV-1 replication. It then seeks to present a possible method of inducing such responses through the procedure of T cell vaccination using activated autoimmune CD4+ T lymphocytes ‘infected’ with inactivated replication-incompetent structurally intact HIV-1 particles. It is hoped that the argument presented here will interest many of those involved in HIV/AIDS research and others in the general scientific community.

Introduction Bacterial meningitis complicates rarely pituitary macroadenomas. The aim of our systematic review is to study the features of the association between bacterial meningitis and pituitary macroadenoma. Methods We conducted a literature search in both MedLine and Google Scholar database from 1967 to October 2016 and reviewed all cases described of the association between bacterial meningitis and pituitary macroadenoma apart from any surgical act and without pituitary apoplexy. Results We found 14 articles describing 16 patients aged of 22-69 years old with a male predominance (sex ratio 4.3). Two patients (12.5%) had a well-documented clinical history of pituitary macroadenoma prior to the diagnosis of bacterial meningitis. Rhinorrhea has been found as the most common symptom through six patients (37.5%). Through the CSF culture, bacterial meningitis among patients suffering of pituitary macroadenoma commonly was due to Streptococcus pneumoniae. The examination in 18.75% of cases revealed signs related to pituitary macroadenoma (ophthalmoplegia and blindness). Six patients (37.5%) had received a treatment by dopaminergic agonist alone and 4 patients (25%) were treated with dopaminergic agonist associated with surgical treatment. Surgical treatment consisted of closure of the osteomeningeal breach in 12.5% (2/16) and tumor resection in 31.25% (5/16). Three patients (18.75%) had benefited tumor resection without prior agonist treatment. The mortality was 12.5% (2/16). Conclusion Our systematic review shows that bacterial meningitis represents a rare initial symptom leading to the diagnosis of invasive pituitary macroadenoma.

Objective The psychosocial aspect of drug use is seldom researched in Caribbean nations. Drug use in the Caribbean has been on the rise since the 1990s. Statistical indicators have established evidence for the increased rates of illegal drug use. This study briefly reviewed these indicators and explored factors that influenced the state of drug affairs in Grenada from 2001 to 2009. Methods Interviews conducted in a semi-structured form were carried out on key stakeholders involved in drug prevention in Grenada. Literary review of pertinent articles from search engines was used to buttress results. Further search through statistical records provided by the Drug Control Secretariat and Grenada Drug Information Network/National Observatory on Drugs (GRENDIN/NOD) was used to obtain information on recent developments surrounding drug related activities in Grenada. Results Trends show marijuana as the drug of choice and males being primarily involved in illegal drug activities. Additionally, cultural, and psychological factors play major roles in the proliferation of the drug problem in Grenada. Conclusion Despite preventive measures used to raise awareness on the dangers of drug use, drug use/abuse/activities are still at an all-time high in Grenada. Focusing on the social, cultural, psychological factors influencing illicit drug activities, and increased cooperation between anti-drug organizations may be effective in curbing illegal drug use in Grenada.

Human-induced pluripotent stem cells (HiPSCs) demonstrate promise in their ability to differentiate into neural cells and ultimately replace the cell types and thereby brain tissue damaged by stroke. This may diminish cognitive impairment due to stroke. Prior to transplantation, an appropriate scaffold must be determined to allow for heightened accuracy by facilitating proper adhesion, differentiation, and proliferation, increasing the likelihood of success, as will be defined in this review, in vivo. This paper aims to provide a review of available biocompatible scaffolds and their efficacy, to provide insight for future research utilizing clinical trials to study stem cell therapy as a form of post-stroke recovery. A systematic review of scaffolds outlined in full-text, peer-reviewed articles with unique experimental data, available on PubMed, will be conducted to determine an ideal scaffold, based on article and scaffold selection criteria best suited for the transplantation of human-induced pluripotent stem cells.

Over the last three decades, an epidemic of obesity has markedly affected patients suffering from mental illnesses such as schizophrenia. Antipsychotic medications used to treat schizophrenia are considered as major culprits. The aim of this review is to first consider risk factors, to then outline negative sequelae of obesity for this population, and finally to address timing and content of recommended clinical interventions. Medical databases were searched with the terms “”weight,” “obesity,” and “schizophrenia.” Selection of articles was guided by date of publication; recent papers are preferentially cited. The main findings were that, in addition to antipsychotic medications, socio-economics, lifestyle, immune factors, and circadian rhythms also contribute to obesity risk. A barrier to effective health promotion within psychiatry has been the concern that fears about gaining weight might stop individuals with schizophrenia from taking needed antipsychotic medication. Recommendations, therefore, are to keep the dose of antipsychotic medication as low as possible, avoid polypharmacy, encourage healthy eating and physical activity, address sleep problems and substance use, monitor weight, blood pressure, and metabolic parameters regularly, utilize motivational interviewing techniques and peer support, pay special attention to special needs such as those of women during pregnancy, and include bariatric surgery as a potential intervention. Conclusion: Besides careful attention to medication regimens, the literature supports the active encouragement and support of patient self-management strategies to both prevent and manage obesity in schizophrenia.

The objective is to evaluate the scientific evolution of articles about vegetarian nutrition. We analyzed the publication of articles of vegetarian nutrition, using the key term ‘vegetarian’ in the National Institutes of Health MEDLINE bibliographic database between 1907 and 2013. We quantified the number of articles in vegetarian nutrition by 5–y time periods, and we classified the kind of journals, the affiliation of the first author, the origin of the study population and the type of articles. The number of articles found in MEDLINE is 3256. The publication rate of vegetarian articles increased steadily, except in periods of 2006-2010 and 2011-2013, and this was explained because the application of “embargo period” for the some publishers. Non-nutrition journals have published more articles on vegetarian nutrition for all periods. It is observed that after 1960 the articles on vegetarian nutrition are proportionately greater than the total published, except in the years 2007, 2008, 2011, 2012 and 2013. The majority of authors were located in Europe (41.7%), followed by North America (26.8%), Asia (16.1%) and Latin America (1.4%). The origin of the study population presented a similar trend being highest in Europe and lowest in Latin America. Original research and review articles represent 52.5% and 20.2% of all publications respectively. We noticed a marked increase in the publication of articles of vegetarian nutrition over the years in absolute and relative terms meaning a growing interest by publication type.

Objective: To prevent childhood obesity, the Chilean government has recently implemented food regulation laws that apply to schools. This paper reviews the literature regarding the challenges in successfully integrating policies to regulate foods offered in schools. In addition, to understand some of the potential implementation barriers, a survey was conducted to evaluate how well food regulation laws were understood and implemented in Chilean schools. Methodology: A narrative literature review was conducted regarding food regulation policies in Chilean schools and potential barriers to implementation. This informed a subsequent descriptive, qualitative survey which was conducted in the Valparaíso region of Chile to examine knowledge, practices, and potential barriers to implementation of the new regulations. Twelve randomly-selected school food kiosk owners completed a survey and structured interview. Visual observations were also performed at each food kiosk. Content analysis identified trends in food items sold and determined the depth of understanding kiosk owners have of a specific new food law, "La Composición Nutricional de los Alimentos y Su Publicidad (20.606)." Key Results: 7 articles in Spanish and 10 in English were reviewed. The literature review revealed that unhealthful food options are readily available to Chilean students in school kiosks. The results of the survey and interview indicated that the school kiosk owners surveyed have a general understanding of the food law. 10 out of 12, however, were unsure of the law's exact contents. Unhealthful food options, inconsistent with regulation 20.606 were observed in all 12 visited kiosks. Conclusion: Evidence from a literature review and the survey findings confirm that unhealthful foods persist in Chilean schools, despite government food regulations. Although the majority of the school kiosk owners acknowledge law 20.606, most lack an understanding of its exact contents and their role in promoting healthier foods in schools. Further education of vendors and school administrators is needed to enhance compliance with the new Chilean food regulations.

Progressive multifocal leukoencephalopathy (PML) is a rare complication associated, inter alia, with rituximab-based lymphoma treatment. PML diagnosis is made easier with the criteria recently published by the American Academy of Neurology. Unambiguous diagnosis of PML can be achieved by demonstration of the histopathological triad comprising:(1) demyelination, (2) bizarre astrocytes and (3) enlarged oligodendroglial nuclei together with detection of viral particles by electron microscopy. However, symptoms of PML may be similar to those observed during lymphoma progression into the central nervous system (CNS). Here we report the case of a patient with diffuse large B-cell lymphoma (DLBCL) treated with R-CHOP who developed clinical signs indicating PML. Intravital diagnostic methods failed to yield an unequivocal diagnosis of PML or lymphoma progression in the CNS. However, a post-mortem examination of brain biopsy specimens performed by electron microscopy demonstrated lesions typical for PML and the presence of viral particles. In addition, immunohistochemical assays identified a massive infiltration of lymphoma cells. The case thus suggests either the extremely rare coexistence of two complications: lymphoma CNS infiltration and PML or induction structural CNS lesions by lymphoma infiltration indistinguishable from PML. The presented findings thus highlight the need for a further review of the current diagnostic criteria for PML.

The aim of the study was to synthesize sub-100nm poly-ε-caprolactone nanoparticles (PCL NP), load them with the mycobacterial protein, ESAT 6 and study the resulting immune responses in CD4+ and CD8+ T cells when incubated with human peripheral blood monocyte derived macrophages that had internalized the PCL NP. The synthesized PCL NP were characterized for size, shape and charge. They were found to be about 60nm in size with spherical shape. MTT assay revealed that the particles were perfectly biocompatible when tested in vitro on THP1 human monocytic cell line. The particles had a slow protein release kinetics and did not degrade appreciably even after 30 days in buffer solution. ELISA was used to quantify the cytokine response of CD4+ and CD8+ T cells when incubated with the monocyte derived macrophages as antigen presenting cells. The result of antigen presentation assay revealed that the antigen loaded PCL NP enhanced Th1 and CD8+ T cell responses significantly compared to the pure antigen. Thus we conclude that PCL NP of 60nm size can be effectively tested as a vaccine adjuvant with resulting activation of Th1/Th2 immunity as well as cytotoxic T cell response.
