General anesthesia induction, tracheal intubation, extubation, and laryngoscopy are associated with specific hemodynamic changes. Tracheal intubation and laryngoscopy are related to sympathetic stimulation and lead to hypertension and tachycardia. Recent studies have shown that dexmedetomidine is safe and effective as it does not depress respiratory function. This meta-analysis aims to compare the efficacy of dexmedetomidine and fentanyl in preventing an increase in heart rate (HR) during intubation among patients undergoing general anesthesia. A systematic literature search was done using PubMed, Cochrane Library, and Embase to assess studies comparing the efficacy of dexmedetomidine and fentanyl in preventing an increase in HR during intubation. A meta-analysis was done utilizing a random-effects model, and mean differences of HR were determined between fentanyl and dexmedetomidine at baseline, one minute, five minutes, and 10 minutes of intubation. In this meta-analysis, eight randomized control trials were included, involving 548 patients (274 in the fentanyl group and 274 in the dexmedetomidine group). The findings showed that significant difference of HR was significantly lower in the dexmedetomidine group than the fentanyl group at one minute of intubation (mean difference = -8.46; P-value = 0.003), at five minutes of intubation (mean difference = -7.51; P-value = 0.001), and at 10 minutes of intubation (mean difference = -5.15; P-value = 0.030). In the current meta-analysis, dexmedetomidine was better than fentanyl in preventing tachycardia following endotracheal intubation. HR was significantly lower at one minute, five minutes, and 10 minutes after intubation in the dexmedetomidine group compared to the fentanyl group.

Diabetic neuropathy (DN) is one of the most prevalent and expensive microvascular consequences of diabetes mellitus (DM), which is noteworthy given that it is frequently both underdiagnosed and undertreated in daily clinical practice. The aim of the current article was to review the efficiency of vitamin B12 supplementation in isolation or in combination therapy for the treatment of diabetic peripheral neuropathy. This meta-analysis was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A systematic electronic search was performed in PubMed and Cochrane Library to identify randomized controlled trials (RCTs) assessing the impact of vitamin B12 outcomes in patients with diabetic neuropathy without putting restrictions on the year of publication. A combination of the following keywords was used: "diabetic neuropathy," "vitamin B12," and "outcomes." The primary outcomes assessed in the current meta-analysis included neuropathic symptoms and vibration perception threshold (VPT). Secondary outcomes included a change in pain score from baseline, total cholesterol (mg/dL), high-density lipoprotein (HDL), and low-density lipoprotein (LDL). A total of six articles were selected to be included in the current meta-analysis. Patients receiving vitamin B12 showed a greater reduction of mean neuropathic symptoms (standardized mean difference (SMD): -0.39, 95% confidence interval (

Adequate periprocedural anticoagulation is important to prevent complications like transient ischemic attack, stroke, severe esophageal injury, and pulmonary vein stenosis. The aim of this meta-analysis was to compare uninterrupted anticoagulation therapy with interrupted anticoagulation therapy for patients with arrhythmias undergoing catheter ablation. The current meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Several online databases were searched, such as PubMed, Cochrane Library, and Embase, to search for relevant randomized controlled trials (RCTs). The primary outcome included thromboembolic events. Secondary outcomes included major bleeding events and minor bleeding events. A total of eight RCTs were included in the current metaanalysis, encompassing a total of 3893 patients. No significant differences were reported in relation to thromboembolic events (RR: 2.39, 95% CI: 0.41-13.97, p-value: 0.33), major bleeding events (RR: 0.99, 95% CI: 0.50-1.96, p-value: 0.98) and minor bleeding events (RR: 1.55, 95% CI: 0.56-4.30, p-value: 0.40) between the two study groups. This meta-analysis did not find any conclusive evidence for the absence of any difference between the two strategies.

The socio-cultural learning theory can be divided into a social and cultural process. Learner's learning occurs within the context rather than anticipating and preparing for the future context. It may happen in the workplace through apprenticeship, experiential learning, or community-based learning. Community-based education and community services have always been part of the students' volunteer services at Avalon University School of Medicine. The importance of community-based education has led to its recent integration into the curriculum. The objective of this study is to observe the community services in the field and to record the perceptions of students regarding community-based education at Avalon University School of Medicine. Methods This is a qualitative study. The research was conducted in the form of an observational study and framework analysis was done. The community-based education and community services were observed and recorded along with individual interviews. Students from different semesters were selected randomly for the interviews. The interviews were audio-recorded and transcribed. Results All interviewed students (100%) reported that they are involved in community services. 53.8% of students were not able to recognize the health issues of Curacao. 84.6% of students recognized and acknowledged the local health issues after reminding them of the activities conducted in the community services. 84.6% of students believed community services enhanced their clinical skills and increased their confidence in communication skills. Conclusion

The aim of the current meta-analysis was to assess the effects of vitamin E on clinical outcomes in individuals with non-alcoholic fatty liver disease (NAFLD). The current meta-analysis was planned, reported, and conducted per the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Two authors systematically searched for all papers using PubMed, Cochrane Central Register, and Embase from inception to October 15, 2022. Outcomes assessed in the current meta-analysis included changes in alanine transaminase (ALT) and aspartate transaminase (AST) from baseline in IU/L. Other outcomes included a change in BMI (kg/cm2), a change in total cholesterol level from baseline (mg/l), and a fibrosis score. Total articles were included in the current meta-analysis, enrolling 569 patients (274 patients in the vitamin E group and 295 in the placebo group). The study found that reduction in ALT levels, AST levels, and BMI was significantly greater in patients in the vitamin E group compared to the placebo group. However, no significant differences were reported in terms of change in fibrosis score and total cholesterol.
