Immunotherapy Usage Has Not Increased Sub-Lobar Pulmonary Resections Despite Reduced Pneumonectomies

Feb 2026

Objective The landscape of non-small cell lung cancer (NSCLC) has changed due to liberalized utilization of computed tomography, developments in immunotherapy and targeted treatments, and guidelines encouraging sublobar resections. We analyzed the implications of these advances for surgical procedures over a 16-year period. Methods The National Cancer Database was used to identify NSCLC incident cases from 2004 to 2020. Histology, stage, grade, and treatment were analyzed using descriptive statistics and logistic regression. Results 2,028,553NSCLC patients were identified. Each year was associated with an increase in Stage I for NSCLC (OR1.05, 95%CI 1.05-1.05) and histological subtypes (adenocarcinoma: OR1.03, 95%CI 1.03-1.04; squamous: OR1.02, 95%CI 1.02-1.02; neuroendocrine: OR1.11, 95%CI 1.11-1.12), with no change in adenosquamous histology. A similar increase was observed for well- or moderately-differentiated histology (OR1.04, 95%CI 1.04-1.04). The proportion of patients receiving chemotherapy decreased (OR0.98, 95%CI 0.98-0.98), while more patients were treated with immunotherapy or targeted therapy, including an increase of 14% using immunotherapy or targeted therapy as first-line treatment. There was a decrease in the likelihood of receiving pneumonectomy (OR 0.91, 95%CI 0.91-0.91). Despite guidelines advocating sublobar resections, these procedures only increased by 1.1% per year. Conclusions Over the 16-year study period, there was a significant trend towards diagnosis of Stage I NSCLC. The most pronounced change in treatment patterns has been more patients receiving immunotherapy and less chemotherapy. Despite a promising decrease in pneumonectomies, the frequency of sublobar resections remains stagnant, indicating limited uptage in current practice.

Rate, Maternal and Fetal Outcome of Cesarean Delivery Performed by IESO at Shenen Gibe General Hospital, Jimma South West Ethiopia: A Descriptive Retrospective Data

Aug 2020 DOI 10.14302/issn.2381-862X.jwrh-20-3439

Background Pregnancy and parturition are events of considerable significance in the life cycle of women. Though it is supposed that the quality of care during labor, birth, and postpartum period plays a great role for adverse outcomes of birth, various reports claimed that cesarean delivery carries a higher maternal and fetal morbidity and mortality compared to vaginal delivery. Therefore, this study assessed the Rate, Maternal and Fetal Outcome of Cesarean delivery performed by IESO at Shenen Gibe General Hospital, Jimma south west Ethiopia. Integrated Emergency surgical officer is a health professional qualified and authorized to perform emergency obstetrical-gynecological and emergency general surgical procedures. The training has started in 2010 in 3 universities and 10 affiliated sites with intake of 43 students. The MSc program in integrated emergency surgery is intended to achieve one of the millennium development goals (MDG): reducing the overwhelming maternal mortality ratio and perinatal mortality rate at the local and national level. (1) Methods Hospital based two-year retrospective descriptive cross-sectional study design was employed and data collected from November to December 2019 in shenen Gibe General Hospital ,Jimma south west Ethiopia. A total of 185 mothers who delivered by cesarean delivery from December 2017 to December 2018 and complete data were included in the study. Data were extracted using structured data collection format and cleaned, and entered into Epi data software version 3.1 and exported into SPSS version 26 for further descriptive analysis. Result Among 2115 deliveries in the two years of retrospective data, a total of 186 mothers were delivered by cesarean section, giving cesarean delivery rate 8.8 %. The leading indication for cesarean delivery was fetal distress (24.2%). Among the total cesarean delivery, 22 neonates were died, giving the proportion of neonate mortality rate 16.8%. One mothers were died following cesarean delivery, giving maternal mortality rate following cesarean delivery 12 per 1000 live births. The leading cause for maternal mortality was hemorrhagic shock Conclusion However, cesarean delivery rate in this study was within the WHO recommended range, the health outcome of mothers and neonates’ following cesarean delivery was not acceptable. The neonatal and maternal mortality following cesarean delivery was 16.8% and12 per 1000 live births respectively. The main cause of neonatal death was birth asphyxia.

The Location and Diameter of the Primary Maxillary Sinus Ostium in Malaysians: A Cone-Beam Computerized Tomography Study

Feb 2020 DOI 10.14302/issn.2768-0207.jbr-20-3194

Rhinosinusitis is one of widely spread diseases in the region and the role of the anatomical variations in its pathogenesis remains unresolved. A retrospective study using CBCT scan was employed to locate and measure the diameter of 320 primary maxillary ostium (PMO) (n = 160 subjects) among the Malay and Chinese populations (Mongoloid race) in Malaysia. Image analysis was performed using the i-CAT Vision Software, employing the multiplanar reconstruction window in which axial, coronal and sagittal planes were visualized in 0.3 mm intervals. The mean diameter of the PMO was significantly larger in the Chinese than the Malay. Females had larger size than the male and bilateral asymmetry was noticed, where the right side PMO was larger than the left side (p < 0.05). In addition, PMO opened more in the posterior third position of the hiatus semilunaris (61.9%) than anterior and middle third. The PMO showed a statistically significant posteriorly placed position in the Chinese than the Malays and this was more evident in the right side PMO (p < 0.01). In conclusion, the PMO commonly opens in the posterior third of the hiatus semilunaris and its diameter is significantly greater in the Chinese female with evidence of bilateral asymmetry. Awareness the anatomical variation of the Ostium diameter and location among the Malay and Chinese populations potentially has important clinical effects during surgical procedures.  

Surgical Site Infection in Cesarean Section Operation: Risk and Management

May 2019 DOI 10.14302/issn.2690-4837.ijip-19-2842

Cesarean sections (CS) are one of the most commonly performed surgical procedures worldwide. There is great variability in the percentage of cesarean sections between countries, varying from 3% to 42.9%5. In the US, approximately 32% of deliveries occur through a cesarean section. Overall, a drastic increase in cesarean section rate has been reported reaching its highest level at the present time. In Brazil, considering the types of births by live births from 2006 to 2016, the national percentage of cesarean section was 52.37%. The variability in this percentage can still be perceived within Brazilian territory. The highest cesarean rate occurred in the Southern region, representing 58.33% of births, while the lowest rate occurred in the Northern region, with 41.79%. It is possible to see the steady increase in the percentage of CS over time, from 45.01% in 2006 to 55.39% in 2016.

Transiently Raised IOP Equivalent to That Experienced During Ocular Surgery Causes Moderate Inflammation but does not Affect Retinal Function or Result in Retinal Ganglion Cell Loss in An Animal Model

May 2017 DOI 10.14302/issn.2470-0436.jos-17-1453

Purpose: High intraocular pressure (IOP) is known to result in retinal ganglion cell (RGC) loss, both with chronically raised intraocular pressure (such as with glaucoma) and with acute raises in pressure (due to injury or acute angle closure). Because IOP is often raised during ocular surgery, the purpose of this study was to evaluate the effect of transient moderate IOP on retinal function, RGC survival and the expression of Connexin 43 (Cx43) and glial fibrillary acidic protein (GFAP), ubiquitously expressed central nervous system (CNS) proteins that are known to be elevated during the retinal inflammatory response to injury. Materials and Methods: Wistar rats were exposed to transient IOP at 40 mmHg for 5 or 30 minutes, and 60 mmHg for 5 minutes (via cannulation of the anterior chamber with a saline reservoir raised to a height corresponding to the desired IOP), mimicking potential IOP rises during surgery such as DSAEK and some laser procedures (LASIK and femtosecond laser cataract surgery). Separate groups of animals had IOP maintained at 10 mmHg for 5 or 30 minutes as cannulation controls, or 120 mmHg for 60 minutes as positive controls. Changes in the optic nerve and retina were assessed immunohistochemically for GFAP and Cx43 expression. Retinal function was assessed using electroretinography (ERG) recorded at baseline and 14 days after the IOP rise and compared with RGC counts. Results: Results showed that there was a differential GFAP labelling pattern observed in the anterior optic nerve in the 40 mmHg 30 minute and 60 mmHg 5 minute groups 4 hours after manipulation. Gap junction protein Cx43 was minimally up-regulated in the retina in the short-term. There was, however, minimal long-term effect on retinal function and no RGC loss. Conclusions: n conclusion, elevations of IOP that are short in duration such as those occurring during surgical procedures, do not cause significant changes long-term in retinal function or RGC survival. Key Messages: Cx43 and GFAP are known to be elevated during the retinal inflammatory response to injury. No previous study has explored the effect of moderate and relatively short increases in IOP on the initial inflammatory response. We observed a mild glial inflammatory response in the anterior optic nerve, but only a minimal up-regulation of Cx43. However, transient and moderate IOP rises did not induce long term disruption to RGC function or number as measured by electrophysiology and RGC counts, respectively. This is applicable to clinical practice, as it means the IOP elevations that occur during some surgical procedures are unlikely to be causing long term damage in retinal function or RGC survival.

Surgical Managment of Intracranial Invasive Aspergillosis in Immunocompetent Patients: Results from 3 Case Reports

Jan 2017 DOI 10.14302/issn.2470-5020.jnrt-16-1288

Cerebral aspergillosis is a severe disease most commonly suspected in immunodeficient patients. The objective of this study is to determine the role of surgery in management of intracranial aspergillosis. We report three cases of immunocompetent patients presenting: posteriror fossa aspergillosis, sphenoidal extended to sellar region aspergillosis and post operative aspergillosis without extracerebral involvement. Microbiology and histological examination were carried out to provide the diagnosis. The patients underwent surgical procedure associated with medical treatment or not. In one case, surgical treatment was efficient. The outcome was good in two cases. Conclusion: Rapid diagnosis of invasive aspergillosis applying radiological and surgical procedures and immediate ignition of antifungal can be life saving.

Primary Abdominal Wall Reinforcement with Synthetic Mesh Following Harvesting of Vertical Rectus Abdominis Myocutaneous Flaps in Multivisceral Pelvic Resections

Dec 2015 DOI 10.14302/issn.2471-7061.jcrc-15-661

Following multivisceral pelvic resections, the pelvis and perineum are often reconstructed using myocutaneous flaps. Abdominal wall defects after harvesting rectus abdominis flaps can be reinforced with mesh. Primary reconstruction using synthetic mesh was presently evaluated. Fifty-eight patients who underwent multivisceral pelvic resection and perineal reconstruction with a vertical rectus abdominis myocutaneous (VRAM) flap, January 2004 to February 2014, were retrospectively reviewed. The abdominal wall was reinforced in 26. Demographics, treatment procedures, surgical procedures, length of hospital and ICU stay, early and late morbidity at the recipient and donor sites were recorded. Patients with mesh reinforcement were significantly younger than those without. There were no further significant differences in patient demographics or treatment procedures between the two groups. In 31% of the patients with mesh, surgery was performed on two consecutive days, although total operating time did not differ significantly. Patients without mesh bled more. Surgery was associated with considerable morbidity, without significant differences in overall complication rate between the two groups. At the recipient site, wound infection/dehiscence was the most common early complication. The group with mesh had higher rate of total flap necrosis necessitating re-operation. At the donor site, wound infection /dehiscence, hernia, or bulge were recorded. Patients with mesh had lower rates of donor site morbidity. Perineal reconstruction with VRAM flap and primary abdominal wall reinforcement with mesh is feasible after multivisceral resection. Our study indicates that primary use of mesh can be applied in potentially contaminated surgical fields in oncologic patients without increasing morbidity and with improved long-term cosmetic results.
