02-2.59), and hazardous alcohol OR1.80 (95% CI, 1.05-3.09). Food insecurity appears to have a slightly protective effect on the odds of whoonga use or reports of use among people adolescents knew OR0.649 (95% CI, 0.541-0.779). Conclusions Larger epidemiological studies should expand the surveillance of hazardous alcohol use and illicit drug use, specifically for recreational use of prescription medication. Granular data is warranted to characterize the patters of use, especially among highly vulnerable populations. Future surveillance studies that explore these multi-level relationships are warranted to further understand this phenomenon among teens in South Africa. © 2020 The Authors.Improving adolescent sleep health is a national priority for ameliorating health and wellbeing (Healthy People 2020), as the majority of adolescents do not get the minimum recommended amount of 8 h of sleep per night. Prior research has identified sex and ethnoracial disparities in adolescent sleep but has been limited by data availability. National studies have collected reported sleep data, while objective sleep data has been available in community samples only. Using new data from adolescents in the Fragile Families and Child Wellbeing Study, a population-based birth cohort study of children born 1998-2000, we are able to characterize sex and ethnoracial disparities in sleep health in the first national sample of actigraphy-assessed sleep health among adolescents. In cross-sectional analyses, we used linear and logistic regression models to assess sex and ethnoracial disparities in weekday sleep duration, timing, and quality measured using actigraphy collected from 738 adolescents at approximately age 15. We identified sex and ethnoracial group differences in weekday and weekend adolescent sleep duration, with larger disparities on weekends than weekdays. Male adolescents had 27-min shorter nightly sleep durations than females on weeknights. Non-Hispanic black adolescents had 32-min shorter nightly sleep durations than non-Hispanic whites on weekdays and 41-min shorter nightly sleep durations on weekends. Tamoxifen While sex disparities persisted after accounting for naps, black-white differences were attenuated by napping such that there was no statistically significant black-white disparity in 24-h sleep on either weekdays or weekends. We did not identify disparities in sleep timing or quality. Future research should investigate the pathways through which these disparities arise, including behavioral and contextual mechanisms. © 2020 The Authors.During the extensive outbreak of coronavirus disease 2019 (COVID-19) in South Korea, many strategies in the hospital setting, such as stratified patient care, the assignment of hospitals/beds by a task force team, and the establishment of dedicated COVID-19 hospitals, dedicated COVID-19 emergency centers, COVID-19 community facilities, and respiratory care split hospitals, were adopted to mitigate community transmission and prevent nosocomial infection. Most of these strategies were used during the Middle East Respiratory syndrome outbreak and were applied again successfully during the COVID-19 outbreak. The reallocation of health care capacity, repurposing of hospitals, and close collaboration between the government and the health care committee might have been the key to successfully addressing the crisis of COVID-19 given the shortage of health care resources. © 2020 Published by Elsevier B.V.Spontaneous corneal perforation is very rare in neonates and children. Peters anomaly is associated with spontaneous corneal perforation. Herein, we describe a case of spontaneous corneal perforation in a 13-day-old Saudi infant who was admitted to the neonatal intensive care unit since birth. This report is important to gain more information about corneal perforation clinical presentation in neonates, investigation, and management. © 2019 Publishing services provided by Elsevier B.V. on behalf of King Faisal Specialist Hospital & Research Centre (General Organization), Saudi Arabia.Background Making an informed choice between the available infant formulas is challenging, as there is no unbiased tool allowing a systematic comparison between the very long lists of infant formula compositions. Aim The aim is to present the Bray-Curtis Similarity Index (BCSI) as a tool for systematic comparison between standard stage-1 infant formula (SS-1-IF) compositions. Methods We obtained the nutrient levels from the packaging labels of 23 SS-1-IFs available in Al-Ahsa, Saudi Arabia, in April 2018. The international legislations that launched infant formula standards endorse targeting the minimum rather than the maximum proposed nutrients levels. Thus, we blindly compared between displayed nutrients levels on each of the 23-studied SS-1-IF and the minimum international proposed nutrient levels via using the BCSI. Results The range of the total displayed components was 38-57. Except for docosahexaenoic acid, all displayed components were within the standard recommended range. The BCSI summarized all displayed nutrients in a single number. The BCSI of the studied SS-1-IF ranged from 0.4141 to 0.79730. We ranked the 23 studied SS-1-IFs based on the higher BCSI is the closer to the minimum proposed nutrient levels. A dendrogram segregated the SS-1-IFs into four clusters based on their BSCI and total numbers of all displayed components. Conclusions We think the BCSI is an appropriate tool for a systematic comparison between SS-1-IFs compositions and may help for choosing a SS-1-IF. © 2020 Publishing services provided by Elsevier B.V. on behalf of King Faisal Specialist Hospital & Research Centre (General Organization), Saudi Arabia.Late preterm infants, defined as newborns born between 340/7-366/7 weeks of gestational age, constitute a unique group among all premature neonates. Often overlooked because of their size when compared to very premature infants, this population is still vulnerable because of physiological and structural immaturity. Comprising nearly 75% of babies born less than 37 weeks of gestation, late preterm infants are at increased risk for morbidities involving nearly every organ system as well as higher risk of mortality when compared to term neonates. Neurodevelopmental impairment has especially been a concern for these infants. Due to various reasons, the rate of late preterm births continue to rise worldwide. Caring for this high risk population contributes a significant financial burden to health systems. This article reviews recent trends in regarding rate of late preterm births, common morbidities and long term outcomes with special attention to neurodevelopmental outcomes. © 2020 Publishing services provided by Elsevier B.
