The severity of dry eye symptoms and risk factors among university students in Saudi Arabia: a cross-sectional study.

Dry eye syndrome (DES) is a tear film disorder caused by increased tear evaporation or decreased production. The heavy workload on the eye and the increased usage of digital screens may decrease blink frequency, leading to an increased evaporation rate and an upsurge in the incidence and severity of DES. This study aims to assess the severity of DES symptoms and the risk factors among university students. A cross-sectional study was conducted at Umm AlQura University to evaluate the severity of DES among students and explore its potential association with digital screen use. Validated questionnaires were used to assess the severity of DES and digital screen usage. The study included 457 participants, of which 13% had symptoms suggestive of severe DES. Furthermore, multiple risk factors had a significant association with the severity of DES, including gender, use of monitor filters, monitor and room brightness, and smoking habits. DES symptoms were prevalent among university students, particularly female students. Although there was no significant association with the duration of screen usage and collage distribution. Other factors however, such as the usage of screen monitors and the brightness of both the monitor and the room, were significantly associated with the severity of DES symptoms.

Weight Loss Effect of GLP-1 RAs With Endoscopic Bariatric Therapy and Bariatric Surgeries.

Background: Different treatment modalities are available for obesity management, including lifestyle changes, pharmacotherapy, endoscopic interventions, and surgeries. Limited evidence is available on the weight loss effect of combining glucagon-like peptide 1 receptor agonists (GLP-1 RAs) with endoscopic bariatric therapy (EBT) and bariatric surgeries (BS). Objectives: In this systematic review, we compared the weight loss effect and metabolic changes of combining GLP-1 RAs with EBT and BS. Methods: Literature searches were performed in the Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials, Embase, PubMed, Google Scholar, and PRISMA databases. Only randomized control trials and retrospective studies were included. Results: A total of 11 studies was included. Nine studies compared BS with and without liraglutide and 2 compared EBT with and without liraglutide. Adding liraglutide to EBT or BS provided significant weight loss when compared with EBT or BS alone. When changes in weight were compared across the studies, EBT with liraglutide showed a weight loss effect comparable to the net weight loss (ie, nadir weight loss after BS-regained weight) achieved following BS alone. Conclusion: This review showcases a promising approach for managing obesity that combines GLP-1 RAs with EBT. This approach is expected to achieve shorter hospital stays, fewer side effects, and longer term weight loss benefits than BS alone. However, additional prospective studies with higher quality, more consistent outcome measures for weight loss and metabolic changes are needed to further evaluate the approach.

Food Allergy: Knowledge and Attitude of Primary School Teachers in Makkah Region, Saudi Arabia.

Food allergy is a serious and potentially life-threatening medical condition that affects both adults and children. School teachers are considered to be among the first line of defense in identifying and responding to such situations, as 22% of food allergic reactions occur in schools. It is, therefore, important to understand the knowledge and attitudes of school teachers toward food allergy. This study is a descriptive, cross-sectional investigation conducted using an online questionnaire from December 2022 to February 2023. We collected data from 413 primary school teachers in Makkah region, Saudi Arabia. SPSS version 21 (IBM Corp., Armonk, NY) was used to analyze the data. Out of 413 teachers who met the inclusion criteria, only 14.5% demonstrated good awareness levels (scoring above 60% on the knowledge questionnaire) regarding food allergy, with young teachers making up the highest proportion as 26.1% of younger teachers had good awareness levels compared to 8.8% of teachers aged 51-60 years (p = 0.012). Additionally, 46.7% of the teachers knew the symptoms of a severe allergic reaction, and only 16.7% knew that they should use an epinephrine pen as the first step in managing a severe allergic reaction. School teachers have insufficient knowledge about food allergies, underscoring the importance of establishing school policies to handle food allergies. Such policies should encompass the adoption of a comprehensive food allergy action plan, training programs for school personnel, and educational campaigns.
