Overweight, Obesity, and Associated Risk Factors among Students at the Faculty of Medicine, Jazan University.

Background and Objectives: This study aimed to determine the prevalence of overweight, obesity, and the associated risk factors among medical students at Jazan University in Saudi Arabia. Materials and Methods: A cross-sectional study was conducted among 228 medical students from their second to sixth academic years at the Faculty of Medicine, Jazan University. A self-administered questionnaire was used to collect data regarding sociodemographic characteristics, physical activity, dietary habits, comorbidities, medication use, family history, and lifestyle factors. Anthropometric measurements including height, weight, and waist circumference were recorded. Chi-square test and binary logistic regression were used to identify the risk factors associated with obesity. Results: The prevalence of overweight and obesity among the participants was 13.3% and 15%, respectively. Hence, the combined prevalence of overweight and obesity is 28.3%. The mean weight was 63.39 ± 18.93 kg, and the mean height was 163.48 ± 9.78 cm. On the other hand, 17.3% of participants were underweight, whereas 54.4% had normal BMI. Most of the participants (61%) did not engage in regular exercise. A high proportion consumed fruits (82.9%) and vegetables (58.8%) 3 or fewer days per week, and 84.2% consumed 3 or fewer meals per day. Fast-food consumption more than 3 days per week was reported by 42.1% of participants. Obesity was not significantly associated with sociodemographic factors, physical activity, dietary habits, comorbidities, medication use, or family histories. However, those with a monthly family income of SAR 15,000-24,999 had significantly lower odds of obesity than those in the lowest income group (OR 0.230, p = 0.045). Conclusions: The prevalence of overweight and obesity among medical students at Jazan University is high. Although no significant associations were found between obesity and most risk factors, this study highlights the need for interventions that promote healthy lifestyles among medical students. Further research is needed to identify effective strategies for preventing and managing obesity in this population.

A Cross-Sectional Study on the Knowledge and Awareness of Lung Cancer and Screening in Jazan Region, Saudi Arabia.

Background: Lung cancer (LC) is the most common cause of cancer-related deaths worldwide. With lung cancer often diagnosed at advanced stages, understanding the local population's awareness levels is crucial for designing effective preventive strategies. By identifying gaps in knowledge, the research aims to inform targeted health education efforts, optimize resource allocation, influence policy development, and contribute to the limited body of research on lung cancer awareness in the region, ultimately fostering improved public health outcomes. Methods: This was a cross-sectional observational study conducted in Jazan region, Saudi Arabia, from July 2022 to June 2023, 671 participants over 18 years old, encompassing both genders, were gsurveyed. Data was collected through a questionnaire covering sociodemographic characteristics and LC-related awareness. SPSS 23 was used for analysis. Factors associated with knowledge scores were explored using independent t-tests and ANOVA, with the Tukey post-hoc test identifying specific group differences. Results: The study included 671 participants, most participants were between 18 and 35 years (73.5%), with 38.5% males and 61.5% females. Lung cancer (LC) awareness was high (95.1%), with 4.9% reporting a family history. Knowledge assessment revealed a mean score of 14.66, with 41.6% having low, 49.5% moderate, and 8.9% high knowledge levels. Correct responses were notable for recognizing LC as a common cancer, a leading cause of death, and associating smoking and shisha with risk. Symptoms were well identified. Screening awareness was at 63.5%, with 78.8% willing to undergo tests if at risk. Age, marital status, and occupation were associated with knowledge, while factors like gender, nationality, residency, education, income, and smoking status showed no significant associations. Conclusion: The findings indicate that there are knowledge gaps related to LC and its screening in Jazan region in Saudi Arabia. Effective awareness programs targeting specific sociodemographic groups are needed to improve the early detection and outcomes.

Effectiveness of Blood Glucose Time in Range to Reduce Risk of Blood Glucose Extrusion and Improve Blood Glucose Metrics in Type 1 Diabetic Patients.

BACKGROUND: With evolving diabetes technology, continuous glucose monitoring (CGM) and time in range have been advanced as critical measurements to assess complications. They have shown improvement in A1C levels and decreased episodes of blood glucose extrusion. AIMS: This study aimed to assess the awareness and utilization of blood glucose time in range and its effectiveness in reducing the risk of blood glucose extrusion and improving blood glucose metrics among patients with type 1 diabetes mellitus. METHODS: A retrospective study included 342 patients who met the inclusion criteria and were using the CGM, aiming for a TIR of 70% daily. Glycemic control was followed using TIR data, blood glucose extrusion frequency (including hyperglycemia and hypoglycemia events), active sensor time, average blood glucose, and glucose management indicator (GMI) levels. RESULTS: A total of 342 individuals participated in this study, the majority of whom were below 18 years of age (62.3%). The hypoglycemic frequency was significantly increased compared to the baseline, and most participants experienced hypoglycemia events (p = 0.0001). The incidences increased over time, with 90.9% and 93% having hypoglycemia at 60 and 90 days (p = 0.0001), respectively. The active scan and sensor time were not followed, which led to the blood glucose target not being achieved, with no improvement throughout the study. Consequently, no improvement occurred in glycemic control. CONCLUSION: CGM technology has been promising and proven effective in improving glycemic. However, our study did not show these benefits as expected, which could be explained by the underutilization and improper use of the CGM.

Transfusion-Associated Graft-Versus-Host Disease in Adults.

Transfusion-associated graft-versus-host disease (TA-GVHD) is a rare but fatal complication of blood transfusion that usually develops two to 30 days following a blood transfusion giving rise to graft versus host disease (GVHD) clinical features that are consisting of fever, skin rash, jaundice, diarrhea, and pancytopenia. The disease is fulminant in most patients with a mortality rate of >90% of cases. The main aim of this review is to enhance awareness among medical practitioners about this fatal disease. Data were extracted manually from the main medical databases (Medline, Scopus, and Google Scholar) after the revision of selected articles and assessed for their contribution to the knowledge of TA-GVHD. TA-GVHD occurs when the viable donor T-cells in the blood or blood products attack the recipient's tissues which his/her immune system is incapable to destroy due to several reasons. The recipient's tissues that are usually involved in TA-GVHD include the liver, intestine, skin, lungs, and bone marrow. Any blood component either whole blood, packed red blood cells (RBCs), platelets, or fresh non-frozen plasma that contains viable T lymphocytes can cause TA-GVHD. Host immunodeficiency, transfusion of fresh blood, and partial human leukocyte antigen (HLA) matching between the donors and the recipients represent the major risk factors of TA-GVHD. Partial HLA matching includes immunocompetent recipients who receive blood from a first-degree relative also, seen in genetically homogenous populations because of high rates of consanguineous marriage. The diagnosis of TA-GVHD is mainly suspected based on clinical manifestations. However, a histopathological study of either skin or rectal biopsy is diagnostic. The treatment of TA-GVHD is generally not effective, unless the patient received emergency stem cell transplantation, while prevention via irradiation of blood or blood products represents the standard of care for this disease. In conclusion, medical practitioners should have a high index of suspicion for this disease. Moreover, future clinical trials targeting and comparing the outcomes of the different therapeutic options for TA-GVHD are required.
