Factors influencing stress and resilience among Egyptian medical students: a multi-centric cross-sectional study.

BACKGROUND: Psychological stress is a common psychological comorbidity among medical students and worsens their quality of life. Psychological resilience is thought to have a protective role against stress. However, evidence regarding the prevalence of stress and resilience alongside their associated factors is scarce, especially in the Middle East. This is the first multicenter, cross-sectional study to investigate resilience and stress among Egyptian medical students. METHODS: The current cross-sectional study was conducted on 2465 university students in seven public universities in Egypt. The universities were selected using the simple randomization method. The data was collected using a self-administered questionnaire consisting of four parts: demographic data, socioeconomic tool represented in the Family Affluence Scale (FAS), the Kessler Psychological Distress Scale (K10), and the Brief Resilience Scale (BRS). Data was analyzed in SPSS version 26 software. RESULTS: The majority of the students were stressed (86.5%), most of whom had severe stress (48.9%). Most of the students had low resilience (49.9%), while only 3.2% had high resilience. In the logistic regression analysis, being a female, living alone, spending long hours on social media, and thinking of suicide or leaving medicine were associated with being stressed and having low resilience. Medical students with low resilience were significantly more liable to stress [Adjusted odds ratio (AOR) = 3.667, confidence interval (CI): 2.709-4.965, P = 0.000], and vice versa [AOR = 3.709, CI: 2.746-5.009, P = 0.000]. Interestingly, high socioeconomic status showed a significant association with high resilience (P = 0.004); nonetheless, it was not associated with stress (P = 0.993). Academic grades were not associated with both the level of stress and resilience. Aging, being in clinical or academic stages, smoking, having a chronic disease, and being financially-supported are neither associated with stress nor resilience. CONCLUSIONS: The present study revealed that Egyptian medical students had low resilience and high stress, with a significant relationship between both of them. Further investigations via longitudinal study design to understand the resilience-stress relationship are recommended. Developing and implementing resilience-improving strategies in medical schools is highly recommended to decrease the prevalence of stress and its subsequent burdens.

Efficacy of different routes of vitamin B12 supplementation for the treatment of patients with vitamin B12 deficiency: A systematic review and network meta-analysis.

BACKGROUND: This systematic review and network meta-analysis aimed to evaluate the three different administration routes of vitamin B12: oral, intramuscular (IM), and sublingual (SL) routes. METHODS: We searched four electronic databases (PubMed, Scopus, Web of Science, and Cochrane CENTRAL Register of Controlled Trials). We included only comparative studies. We performed a frequentist network meta-analysis to measure network estimates for the relative outcomes. Moreover, we conducted a pairwise meta-analysis using a random effect model to obtain direct estimates for outcomes. All outcomes were continuous, and the relative treatment effects were pooled as mean difference (MD) with 95% confidence intervals. RESULTS: Thirteen studies were included in the meta-analysis, with a total of 4275 patients. Regarding increasing vitamin B12 levels, the IM route ranked first, followed by the SL route (MD = 94.09 and 43.31 pg/mL, respectively) compared to the oral route. However, these differences did not reach statistical significance owing to the limited number of studies. Regarding the hemoglobin level, the pooled effect sizes showed no difference between all routes of administration that could reach statistical significance. However, the top two ranked administration routes were the oral route (78.3) and the IM route (49.6). CONCLUSION: All IM, oral, and SL routes of administration of vitamin B12 can effectively increase the level of vitamin B12 without significant differences between them, as thought previously. However, the IM route was the top-ranked statistically but without clinical significance. We found no significant difference among studied administrated routes in all other CBC parameters and homocysteine levels.

Mobile schwannoma of the thoracolumbar spine: A case report.

INTRODUCTION: Schwannoma, a benign nerve sheath tumor originating from Schwann cells, can migrate within the spine due to various factors, impacting surgical planning. Unforeseen movement complicates treatment, and it is considered a very rare tumor. CASE PRESENTATION: A 24-year-old woman complained of persistent back pain and was examined at a neurosurgery clinic. Initial MRI found a spinal lesion that later moved, leading to two surgeries. The diagnosis was a Schwannoma, confirmed by examining the tissue under a microscope, showing characteristic features of a Schwannoma, specifically Antoni type A with recent hemorrhage. DISCUSSION: Schwannoma, a rare nerve cell tumor, often migrates within the spine due to its lack of attachment within the dura. The tumor's movement can be triggered by various factors like nerve root laxity, pressure changes, body positioning, or medical procedures. A case study discussed a woman with back pain; her tumor migrated between two MRI scans, showcasing a common migration pattern. Lower back pain commonly manifests as a primary symptom in most cases. Imaging techniques such as myelography and intraoperative ultrasound assist in locating and managing these mobile tumors, advocating for their utilization to minimize surgical complications. CONCLUSION: Reported a rare mobile thoracolumbar schwannoma from nerve sheath cells. Its mobility complicates surgery; precise imaging like intraoperative MRI and ultrasound are crucial for localization, preventing complications.

Dose-dependent efficacy and safety of licogliflozin on obese adults: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND AIM: Licogliflozin is a dual SGLT1/2 inhibitor acting on the intestine and kidney by reducing glycemic and calorie content. We aimed to determine the efficacy and safety of licogliflozin on Anthropometric measurements and cardiometabolic parameters in obese participants. METHODS: We systematically searched the PubMed, Cochrane Library, Scopus, and Web of Science databases for randomized controlled trials (RCTs) relevant to our eligibility criteria. We performed a subgroup analysis based on licogliflozin doses and the diabetic state of participants. This meta-analysis was registered on PROSPERO (CRD42021286936). RESULTS: We identified five RCTs with a total of 905 obese and overweight participants. All participants had a weight reduction of 2.43 kg (95% CI: -3.17 to -1.69, p < 0.00001) compared with placebo. The mean difference in HbA1c of obese diabetic patients was (MD: -0.30%; 95% CI: -0.45, -0.16); I2 = 46% in favor of licogliflozin. The incidence of serious adverse events, all-cause mortality, headache, nausea, and vomiting were similar between licogliflozin and placebo (p = 0.72, 0.97, 0.09, 0.53, and 0.89, respectively). However, there was a higher incidence of diarrhea in the licogliflozin group. CONCLUSION: We found that licogliflozin was safe and tolerable. It reduces body weight significantly. Moreover, it improves glycemic control and other cardiometabolic parameters.
