The overlooked trio: #sleep duration, sampling time and #physical exercise alter levels of olink-assessed blood biomarkers of cardiovascular risk

Biomarker profiling from biofluids such as blood are widely measured in clinical research, using for example Olink proteomics panels. One such research focus area is cardiovascular disease (CVD), for which chronic sleep restriction (SR) is a risk factor. However, it remains unclear whether blood levels of commonly measured CVD biomarkers are sensitive to acute dynamic… Continue reading The overlooked trio: #sleep duration, sampling time and #physical exercise alter levels of olink-assessed blood biomarkers of cardiovascular risk

Posttraumatic #Stress Disorder and Obstructive Sleep #Apnea in Twins

Key PointsQuestion  What is the association of posttraumatic stress disorder (PTSD) with obstructive sleep apnea (OSA) after accounting for acknowledged medical risk factors for OSA?Findings  In a cross-sectional study of 132 older male veteran twins discordant for PTSD undergoing in-laboratory polysomnography, current PTSD diagnosis and symptoms were associated independently with OSA, even after controlling for demographics, behavioral… Continue reading Posttraumatic #Stress Disorder and Obstructive Sleep #Apnea in Twins

Older adults at greater risk for #Alzheimer’s disease show stronger associations between sleep #apnea severity in #REM sleep and verbal memory

Obstructive sleep apnea (OSA) increases risk for cognitive decline and Alzheimer’s disease (AD). While the underlying mechanisms remain unclear, hypoxemia during OSA has been implicated in cognitive impairment. OSA during rapid eye movement (REM) sleep is usually more severe than in non-rapid eye movement (NREM) sleep, but the relative effect of oxyhemoglobin desaturation during REM… Continue reading Older adults at greater risk for #Alzheimer’s disease show stronger associations between sleep #apnea severity in #REM sleep and verbal memory

Sleep #Apnea and Incident #Stroke in a National Cohort of Black and White Adults

Background and ObjectivesRacial/ethnic differences have been documented in the relationship between obstructive sleep apnea (OSA) and stroke incidence, yet racial differences in OSA symptoms or treatment and their relationship with stroke incidence are underexplored and may contribute to stroke disparities. We comprehensively examined OSA symptoms and their relationships to stroke incidence by race/ethnicity.MethodsData were collected… Continue reading Sleep #Apnea and Incident #Stroke in a National Cohort of Black and White Adults

Obstructive sleep apnoea and 12-month weight loss in adults with class 3 obesity attending a multidisciplinary weight management program

Although there is a strong association between obesity and obstructive sleep apnoea (OSA), the effects of OSA and CPAP therapy on weight loss are less well known. The aim of this study in adults with class 3 obesity attending a multidisciplinary weight management program was to assess the relationship between OSA and CPAP usage, and… Continue reading Obstructive sleep apnoea and 12-month weight loss in adults with class 3 obesity attending a multidisciplinary weight management program

Fecal #microbiota transplantation from mice exposed to chronic intermittent hypoxia elicits #sleep disturbances in naïve mice

Obstructive sleep apnea (OSA) is a chronic prevalent condition characterized by intermittent hypoxia (IH) and sleep fragmentation (SF). Evidence suggests that OSA can alter the gut microbiome (GM) diversity and composition that may then promote the occurrence of some of the OSA-associated morbidities. However, it is unclear whether perturbations in the GM caused by IH… Continue reading Fecal #microbiota transplantation from mice exposed to chronic intermittent hypoxia elicits #sleep disturbances in naïve mice

Sudden death in individuals with obstructive sleep #apnoea: a systematic review and meta-analysis

Over 1 billion individuals worldwide experience some form of sleep apnoea, and this number is steadily rising. Obstructive sleep apnoea (OSA) can negatively influence one’s quality of life and potentially increase mortality risk. However, the association between OSA and mortality has not been reliably estimated. This meta-analysis estimates the risk of all-cause and cardiovascular mortality in… Continue reading Sudden death in individuals with obstructive sleep #apnoea: a systematic review and meta-analysis

The noradrenergic agent reboxetine plus antimuscarinic hyoscine butylbromide reduces sleep #apnoea severity: A double-blind, placebo-controlled, randomised crossover trial

Recent animal and human physiology studies indicate that noradrenergic and muscarinic processes are key mechanisms that mediate pharyngeal muscle control during sleep. The noradrenergic agent reboxetine combined with the anti-muscarinic hyoscine butylbromide has recently been shown to improve upper airway function during sleep in healthy individuals. However, whether these findings translate to the clinically relevant… Continue reading The noradrenergic agent reboxetine plus antimuscarinic hyoscine butylbromide reduces sleep #apnoea severity: A double-blind, placebo-controlled, randomised crossover trial

Obstructive Sleep #Apnea as a Risk Factor for Intracerebral #Hemorrhage

To determine whether obstructive sleep apnea (OSA) is associated with intracerebral hemorrhage (ICH) risk, we assessed premorbid OSA exposure of patients with nontraumatic ICH and matched controls. Methods: Ethnic/Racial Variations of Intracerebral Hemorrhage is a multicenter, case-control study evaluating risk factors for ICH that recruited 3000 cases with ICH and 3000 controls. OSA status was… Continue reading Obstructive Sleep #Apnea as a Risk Factor for Intracerebral #Hemorrhage
