Internet Addiction and Sleep Disorders among Medical Students.

Background: Considering the increasing use of the Internet in Iranian society, especially among students, and the importance of sleep quality, the present study investigated the relationship between sleep quality and Internet addiction among medical students in Shiraz. Methods: In this descriptive-analytical study, the sample included students of the Shiraz University of Medical Sciences who were selected by a multistage sampling method in 2018. Each faculty was considered to be stratified, and the samples were selected from all strata by simple random sampling. A total of 400 student questionnaires were eligible for analysis. The level of sleep disturbance was measured using the Pittsburgh Sleep Quality Index (PSQI), and Young's Internet Addiction Test (IAT) was used to evaluate Internet addiction. Cronbach's alpha for PSQI and IAT was 0.77 and 0.93, respectively. Results: 109 (%28.9) and 58 (%14.4) of all the people under study were at risk of Internet addiction or poor sleep quality, respectively. The highest percentage of poor sleep quality was in those who were addicted to the Internet (60%), but the lowest percentage was observed in the group without addiction (27%). In addition, there was a significant correlation between Internet addiction and subjective sleep quality (r = 0.191, p = 0.05), sleep latency (r = 0.129, p = 0.01), sleep duration (r = 0.119, p = 0.01), habitual sleep efficiency (r = 0.186, p = 0.05), sleep disturbances (r = 0.169, p = 0.01), use of sleeping medication (r = 0.203, p = 0.05), and daytime dysfunction (r = 0.188, p = 0.05). Conclusion: These findings help national health officials and planners in Iran to design appropriate and effective interventions to improve students' health and prevent Internet addiction.

The global survival rate of graft and patient in kidney transplantation of children: a systematic review and meta-analysis.

BACKGROUND: This study is a systematic review and meta-analysis on published studies about the Global Survival Rate of Graft and Patients in the Kidney Transplantation of children. METHODS: Studies that investigated the survival rate of kidney transplants published until the 30th of December 2020 were selected using a systematic search strategy in the following databases: Medline, Embase, Scopus, ProQuest, ISI Web of Science, and Cochrane. The extracted data were entered into the Excel software and STATA 16.0. The search identified 6007 study references. From the total, we excluded 1348 duplicates, 3688 reference titles and abstracts that were deemed irrelevant, and 846 references that were not original articles (i.e., letter, commentary, review) or did not meet the inclusion criteria. As such, 89 studies involving 12,330 participants were included in this meta-analysis. RESULTS: In this study 1, 3, 5, 7 and 10-year survival rates of graft were estimated to be 92, 83, 74.40, 67.10, and 63.50%, respectively. Also, 1, 3, 5, 7 and 10-year survival rates of patients were estimated to be 99.60, 97.30, 95.20, 74.60, and 97.90%, respectively. CONCLUSIONS: The findings suggest differences in graft and patient survival among children with kidney transplants. Although differences in ethnic origin, incompatibility with deceased donor kidneys, and types of kidney disease are unavoidable, interventions to improve preventive and living-donor transplantation are particularly needed in minority groups. In addition, more research is needed to establish and address the contribution of medical and sociocultural barriers to preferential treatment of these groups.
