Association of sleep quality with sociodemographic factors and lifestyle in adolescents from southern Brazil

World Journal of Pediatrics 2018年第4期14卷 383-391页

作者： Tiago rodrigues de Lima Diego Augusto Santos Silva Physical Education Department Federal University of Santa CatarinaProfessor Clementino de Britto Street362 ap 334 CapoeirasFlorianópolisSanta CatarinaBrazil

Background Good sleep quality is an essential component for growth, development, and physical and mental health of the individual, in addition to being a positive indicator of health and well-being. The objective of this study was to estimate the prevalence of poor sleep quality and to identify the association of poor sleep quality with sociodemographic factors, lifestyle, weight status, and associated aerobic fitness in adolescents. Methods This study included 1110 students aged 14–19 years from city of S?o José/SC, Brazil. Sleep quality of the subjects was assessed using a questionnaire and classified as adequate and low. Independent variables were gender, age, monthly household income, maternal education, school shift, global physical activity, proper diet, screen time, sleeping hours of full week, sleeping hours of weekdays, sleeping hours of weekends, weight status, and aerobic fitness. Binary logistic regression was used to estimate odds ratios and confidence intervals of 95%. Results Prevalence of poor sleep quality was 60.4%. More likely to have poor sleep quality were identified in female students (OR 1.68, 95% CI 1.11–2.55), whose mothers had higher levels of education (OR 1.44, 95% CI 1.20–1.73) and low aerobic fitness (OR 1.80, 95% CI 1.02–3.19). Conclusion Adolescents who were most likely to report poor sleep quality were female, those whose mothers had a higher educational level and had low aerobic fitness. Students with sedentary risk behavior were less likely of reporting poor sleep quality.

Neutropenic enterocolitis

引用

World Journal of Gastroenterology 2017年第1期23卷 42-47页

作者： Fabio G rodrigues Giovanna Dasilva Steven D Wexner Department of Colorectal Surgery Cleveland Clinic FloridaWestonFL 33331United States

Neutropenic colitis is a severe condition usually affecting immunocompromised patients. Its exact pathogenesis is not completely understood. The main elements in disease onset appear to be intestinal mucosal injury together with neutropenia and the weakened immune system of the afflicted patients. These initial conditions lead to intestinal edema, engorged vessels, and a disrupted mucosal surface, which becomes more vulnerable to bacterial intramural invasion. Chemotherapeutic agents can cause direct mucosal injury (mucositis) or can predispose to distension and necrosis, thereby altering intestinal motility. This article aims to review current concepts regarding neutropenic colitis’ pathogenesis, diagnosis, and management.
