Background: Night shift duties are crucial in the ICU to ensure care continuity, where critically ill patients require round-the-clock care. However, cumulative night shift duties may disturb circadian rhythm, insomnia, fatigue, and depression, and require further elucidation. Objectives: This study aims to examine the negative consequences of various night shift patterns on insomnia, fatigue, and mental health of ICU Workers. Methods: A cross-sectional study examined how cumulative night shift duty affects insomnia, fatigue, and mental health in critical care providers (CCPs). Results: A total of 1006 participants completed this study between June 2022 and March 2023, including 54.5 % males. About 35 % were between 20 and 30 years of age, and Respiratory Therapists accounted for approximately 46.5 % of the entire sample. Most of our respondents (476; 47 %) reported working night shifts, with a monthly range of 8–15 nights. The prevalence rates for moderate to severe clinical insomnia, fatigue, and moderate to severe depression were 42 %, 48 %, and 32 %, respectively. CCPs working 8–15 nights had a 2-fold risk of clinical insomnia than those working fewer than eight nights with (AOR) and 95 % (CI) of 2.12 and 1.41–3.20, while those working ≥16 nights per month had a greater incidence of clinical insomnia compared to those working

AbstractIn this study Triterpenoids have been extracted from green tea powder, after that it is action on two species of yeast Candida albicans and Candida tropicalis and two species of bacteria staphylococcus aureus and pseudomonas aeruginosa had been tested. This test shows variable degrees and effects, the growth of Candida albicans yeast has been inhibited 47% at a concentration of 12.5 µg/ml while the growth of Candida tropicalis has been inhibited by 43% at the same concentration while of 50 mg/ml pseudomonas aeruginosa had been inhibited by 66% and staphylococcus aureus by 58%at the same conc.الخلاصةفی هذا البحث تستخلص التربنویدات من مسحوق الشای الاخضر ثم یختبر تاثیرها فی نمو جنسین من الخمائر هما Candida albicans ، Candida tropicalis وجنسین من البکتریا هما staphylococcus aureus and pseudomonas aeruginosa وقد اظهرت درجات مختلفة من التاثیر اذ تثبط نمو خمیرة Candida albicans بنسبة 47%عند الترکیز5. 12 مایکروغرام/مل وتثبط نمو خمیرة Candida tropicalis بنسبة 43% عند الترکیز نفسه وتثبط نمو بکتریا pseudomonas aeruginosa بنسبة(66%) عند الترکیز 50 مایکروغرام /مل وتثبط نمو بکتریا staphylococcus aureus بنسبة 58% عند نفس الترکیز ولم یظهر ای تاثیر عند الترکیز 25 مایکروغرام /مل فما دون.
