Article Abstract
Background: Both long and short sleep durations may lead to cognitive decline in the elderly individuals, though the underlying mechanisms remain unclear.
Aims: To explore the mediating mechanism of activities of daily living and depression on different sleep durations and cognitive function in older Chinese older adults.
Methods: This retrospective study used data from 5,899 older adults who completed the 2018 China Health and Retirement Longitudinal Surveys. We used the PROCESS macro in SPSS to determine the chain mediating effect of ADL and depression on the relationship between different sleep durations and cognitive functions.
Results: (1) There were significant correlations among sleep duration, ability to perform ADL, depression, and cognitive function. (2) For sleep durations ≤ 7 h/night or > 7 h/night, ADL and depression play a chain mediating role in the relationship between sleep duration and cognitive function.
Conclusions: Shorter or longer sleep durations were associated with cognitive decline by weakening ADL and worsening depression, which suggests that medical personnel should take action to correct abnormal sleep duration in older adults. Timely treatment of ADL impairment and depression may help prevent cognitive decline.

Department of Ophthalmology, The Second Affiliated Hospital of Anhui Medical University, Hefei, 230601, People's Republic of China.
Objective: To investigate the prevalence of dry eye disease (DED) among children and adolescents aged 9 to 19 years in Fengyang County, and to explore the associations of sleep duration and social jetlag with DED, with the aim of providing scientific evidence for sleep-based interventions to prevent DED in this population.
Methods: Between November and December 2023, 14 primary and secondary schools were randomly selected in Fengyang County, Chuzhou City, Anhui Province, China. Students from Grade 4 to Grade 12 (aged 9-19 years) were invited to participate.
Individual, Social and Environmental Influences on Sleep in Latino Pre-Adolescents: A Qualitative Analysis.

University of Southern California, Los Angeles, USA.
A community-based qualitative study identified multilevel influences on sleep duration, quality, and timing in 10 to 12-year-old Latino pre-adolescents via 11 focus groups with 46 children and 15 interviews with parents. An iterative content analysis revealed three themes negatively and positively impacted sleep: (1) Individual-level; (2) Social-level; and (3) Environmental-level influences. At the individual level, use of technology (e.

Background: Adolescents faced increased psychological distress during the COVID-19 pandemic. While prior research suggests physical activity (PA) may mitigate depression and anxiety, findings have been inconsistent and rarely focus on adolescents during prolonged lockdowns. This study addresses this gap by evaluating the association between daily PA duration and mental health outcomes among Chinese adolescents during the pandemic.

Background Delirium and sleep disturbances are common in critically ill patients and are associated with adverse outcomes, including prolonged intensive care unit (ICU) stays. Ramelteon, a melatonin receptor agonist, may improve sleep and reduce delirium by regulating circadian rhythms. This study evaluated the efficacy of ramelteon in shortening ICU stay, decreasing delirium incidence and duration, and improving sleep quality in critically ill patients.

Background: Sedentary behavior (SB) and the absence of physical activity (PA) have become increasingly prevalent in modern societies due to changes in physical and social-environmental conditions, particularly in university students. This cross-sectional study aimed to describe and identify the prevalence and correlates of self-reported and accelerometer-determined SB and PA of German university students.
Methods: A convenience sample of 532 students participated in a questionnaire survey during the lecture period in the summer term 2018.
