January 2025
U.S. Department of Veterans Affairs National Center for PTSD, VA Connecticut Healthcare System, West Haven, CT, USA.
Background And Objectives: Insomnia symptoms are more prevalent in older age and may be impacted by negative perceptions of aging; however, more research is needed. The present study characterizes the relationship between negative aging stereotypes and clinical insomnia symptoms in a nationally representative sample of older United States (U.S.

Department of Rehabilitation Medicine, Erasmus MC, University Medical Center Rotterdam, Rotterdam, the Netherlands.
Purpose: To explore associations of environmental and personal factors, participation, and health-related quality of life (HR-QoL) with physical behavior (PB) after subarachnoid hemorrhage (SAH).
Materials And Methods: PB, expressed in duration and distribution of physical activity (PA; walking, running, cycling) and sedentary behavior (SB; lying/sitting) and PA intensity was assessed with the Activ8 accelerometer during 7 days. Environmental and personal factors (social influence, health-condition, illness-perception, self-efficacy, fatigue, mood, kinesiophobia, cognition, coping, sleep), participation and HR-QoL, were assessed with validated questionnaires.
Sleep spindles and slow oscillations predict cognition and biomarkers of neurodegeneration in mild to moderate Alzheimer's disease.

Unitat de Trastorns Cognitius, Cognition and Behavior Study Group, Hospital Universitari Santa Maria Universitat de Lleida, Lleida, Spain.
Introduction: Changes in sleep physiology can predate cognitive symptoms by decades in persons with Alzheimer's disease (AD), but it remains unclear which sleep characteristics predict cognitive and neurodegenerative changes after AD onset.
Methods: Using data from a prospective cohort of mild to moderate AD (n = 60), we analyzed non-rapid eye movement sleep spindles and slow oscillations (SOs) at baseline and their associations with baseline amyloid beta (Aβ) and tau and with cognition from baseline to 3-year follow-up.
Results: Higher spindle and SO activity predicted significant changes in Aβ and tau at baseline, lower Alzheimer's Disease Assessment Scale Cognitive Subscale (better cognitive performance) score, and higher Mini-Mental State Examination score from baseline to 36 months.
Prevalence and Pattern of Obstructive Sleep Apnea among Undergraduate Students in Tertiary Institutions, Kwara State, Nigeria.

Department of Epidemiology & Community Health, University of Ilorin, Nigeria.
Background: Sleep is a very important physiologic process which is necessary to maintain a state of well-being. Obstructive Sleep Apnea (OSA) is prevalent among all age groups with variations in presentation and severity. It is often underreported, especially among young people in the Low- and Middle-Income Countries LMICs.

December 2024
Socio-Spatial Determinants of Health (SSDH) Laboratory, Population and Community Health Sciences Branch, Division of Intramural Research, National Institute on Minority Health and Health Disparities, National Institutes of Health, Bethesda, Maryland.
Introduction: Research suggests that perceived neighborhood social environments (PNSE) may contribute to gender and race/ethnicity-based sleep disparities. Our study aimed to examine associations between PNSE factors and adolescents' sleep patterns. As a secondary aim, we examined how gender and race/ethnic groups might moderate these associations.
