Medical students carry a large academic load which could potentially contribute to poor sleep quality above and beyond that already experienced by modern society. In this global literature review of the medical students' sleep experience, we find that poor sleep is not only common among medical students, but its prevalence is also higher than in non-medical students and the general population. Several factors including medical students' attitudes, knowledge of sleep, and academic demands have been identified as causative factors, but other potential mechanisms are incompletely understood. A better understanding about the etiology of sleep problems in medical trainees is essential if we hope to improve the overall quality of medical students' lives, including their academic performance. Sleep self-awareness and general knowledge appear insufficient in many studied cohorts, so increasing education for students might be one beneficial intervention. We conclude that there is ample evidence for a high prevalence of the problem, and research in this area should now expand towards initiatives to improve general sleep education for medical students, identify students at risk, and target them with programs to improve sleep.
To summarize information obtained from original research about barriers to access of primary healthcare by Canadian immigrants' and to identify research gaps. Electronic databases of primary research articles and grey literature were searched without restricting the time period. The preferred reporting items for systematic reviews and meta-analyses statement was followed for literature selection. Articles were selected based on three criteria: (a) the study population was Canadian legal immigrant(s), (b) the research was about the barriers to accessing primary healthcare in Canada, and (c) the article was written in English. Relevant information from the articles was extracted into tabular format and classified for thematic analysis. Identified barriers were grouped into five themes: cultural, communication, socio-economic status, healthcare system structure and immigrant knowledge. The barriers to accessing primary healthcare in each of these categories can provide insight and subsequent direction for changes needed to improve immigrant care and mitigate their deterioration in health status. The demographic and ethno-cultural distributions of the study populations across the provinces highlight the need to expand research to encompass more varied immigrant groups across more regions of Canada, including more research on male immigrants and immigrant seniors, and to increase research related to health care providers' perspectives on the barriers.
Brachial-ankle pulse wave velocity (baPWV) is a relatively new non-invasive measure of arterial stiffness obtained using an automated system. We assessed the relationship between baPWV and 6.5-year overall mortality from the Takashima cohort study. The baPWV was measured in 2642 participants at baseline. When participants were divided into tertiles, all-cause mortality increased significantly as baPWV increased (Po0.001). Participants in the highest baPWV tertile showed an increased risk of all-cause mortality evidenced by a multivariable adjusted hazard ratio of 6.8 (95% confidence interval: 1.4-32.8) as compared with the lowest tertile. The present study demonstrated that increased baPWV is an independent predictor of all-cause mortality in the Japanese population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
