Objective We reviewed the available literature on patients with coronary artery disease undergoing isolated coronary artery bypass grafting (CABG) with either single (SAG) or multiple arterial grafting (MAG). Methods Original research studies that evaluated the long-term survival of MAG versus SAG were identified, from 1995 to 2022. The median overall survival (OS) and event-free OS were the primary endpoints. Comparison of median OS between the right internal mammary artery (RIMA) and radial artery (RA) as a second arterial conduit was the secondary endpoint. Subgroup analyses were performed regarding patients older than 70 years, with diabetes mellitus, and females. A sensitivity analysis was performed with the leave-one-out method. Results Forty-four studies were included in the qualitative and thirty-nine in the quantitative synthesis. After pooling data from 180 to 459 patients, the MAG group demonstrated a higher OS (HR, 0.589; 95% CI, 0.58–0.60; p < 0.0001) and event-free OS compared with the SAG group (HR, 0.828; 95% CI, 0.80–0.86; p < 0.0001). In addition, RITA was associated with superior OS compared with RA as a second arterial conduit (HR, 0.936; 95% CI, 0.89–0.98; p = 0.009). MAG was also superior to SAG in patients over 70 years, females, and patients with diabetes mellitus. Sensitivity analysis demonstrated a small-size study effect on the female subgroup analysis. Conclusion The present meta-analysis indicates that MAG is associated with enhanced survival outcomes compared to SAG for patients undergoing isolated CABG.

Objective: Treating burn patients in the battlefield is one of the biggest challenges that military doctors and medical personnel can face. Wound patterns have been changed over time due to the introduction of new weapons, and many different aspects play a major role in the management of those burns nowadays. There is a potential gap in care of burn patients in war zones. Methods: A thorough literature search in PubMed, scientific journals, and Internet sites was conducted in regard to burn patients and trauma in war zones. Results: It is crucial for military surgeons to be able to stabilize burn patients during wartime conflicts, especially those patients who suffer from extreme burn injuries, as specialized treatment should be given. Medical personnel should be aware of all medication types used, the ways to minimize the risk of bacterial infection, and the ways to keep the injured safe. Conclusions: Injured civilians with burn trauma in the field of battle are deserving care, and special recognition should be given to the non-governmental organizations (NGOs) that strive to ease human suffering in war zones. Proper management of burn patients in war zones is crucial, and military medical staff and NGOs can play a key role in that purpose.

Objective: We conducted a thorough literature search on patients with central non-small cell lung cancer (NSCLC) undergoing either extended sleeve lobectomy (ESL) or pneumonectomy (PN). Methods: We identified all original research studies that compared the long-term survival of ESL versus PN from 1990 to 2022. The primary endpoints were the median overall survival (OS) and disease-free survival (DFS). Complications, operative mortality, and the reoperation rate were the secondary endpoints. Regarding the primary endpoints, independent patient data were extracted from the included studies, and pooled Kaplan–Meier curves were constructed. A sensitivity analysis was performed using the leave-one-out method. Results: Nine studies were included in the qualitative and seven in the quantitative synthesis, including 431 patients. Patients in the ESL group demonstrated a significantly higher OS compared with the PN group (HR, 0.63; 95% CI, 0.46–0.87; p = 0.005). In addition, patients undergoing ESL presented a significantly higher DFS compared to the PN group (HR, 0.57; 95% CI, 0.40–0.80; p = 0.004). These findings were further validated with a sensitivity analysis. The most common complications in the ESL group were bronchopleural fistula (4.6%), stricture (3.1%), prolonged air leakage (7.3%), sputum retention (4.6%), pneumonia (7.7%), and pulmonary vein thrombosis (1.5%). ESL was associated with a low reoperation rate (1.5%) and operative mortality (1.2%). Conclusions: The present meta-analysis indicates that ESL is associated with enhanced survival outcomes compared to PN for patients with central NSCLC. Further randomized controlled trials are necessary to validate our findings.
