IntroductionDietary supplements are touted for cognitive protection, but supporting evidence is mixed. COSMOS-Mind tested whether daily administration of cocoa extract (containing 500 mg/day flavanols) versus placebo and a commercial multivitamin-mineral (MVM) versus placebo improved cognition in older women and men.MethodsCOSMOS-Mind, a large randomized two-by-two factorial 3-year trial, assessed cognition by telephone at baseline and annually. The… Continue reading Effects of cocoa extract and a multivitamin on cognitive function: A randomized clinical trial

Periodontal health, cognitive decline, and dementia: A systematic review and meta-analysis of longitudinal studies
AbstractBackgroundEmerging evidence indicates that poor periodontal health adversely impacts cognition. This review examined the available longitudinal evidence concerning the effect of poor periodontal health on cognitive decline and dementia.MethodsComprehensive literature search was conducted on five electronic databases for relevant studies published until April 2022. Longitudinal studies having periodontal health as exposure and cognitive decline and/or… Continue reading Periodontal health, cognitive decline, and dementia: A systematic review and meta-analysis of longitudinal studies
Association of Daily Step Count and Intensity With Incident Dementia in 78 430 Adults Living in the UK
Key PointsQuestion Is there a dose-response association of daily step count and intensity with incidence of all-cause dementia among adults living in the UK?Findings This cohort study of adults assessed with wrist-worn accelerometers found that accruing more steps per day was associated with steady declines in dementia incidence risk, up to 9800 steps per day, beyond which… Continue reading Association of Daily Step Count and Intensity With Incident Dementia in 78 430 Adults Living in the UK
Effect of statin therapy on muscle symptoms: an individual participant data meta-analysis of large-scale, randomised, double-blind trials
BackgroundStatin therapy is effective for the prevention of atherosclerotic cardiovascular disease and is widely prescribed, but there are persisting concerns that statin therapy might frequently cause muscle pain or weakness. We aimed to address these through an individual participant data meta-analysis of all recorded adverse muscle events in large, long-term, randomised, double-blind trials of statin… Continue reading Effect of statin therapy on muscle symptoms: an individual participant data meta-analysis of large-scale, randomised, double-blind trials
Contribution of Common Genetic Variants to Risk of Early Onset Ischemic Stroke
Background and Objectives: Current genome-wide association studies of ischemic stroke have focused primarily on late onset disease. As a complement to these studies, we sought to identifythe contribution of common genetic variants to risk of early onset ischemic stroke.Methods: We performed a meta-analysis of genome-wide association studies of early onset stroke (EOS), ages 18-59, using individual level… Continue reading Contribution of Common Genetic Variants to Risk of Early Onset Ischemic Stroke
Sleep patterns, genetic susceptibility, and incident cardiovascular disease: a prospective study of 385 292 UK biobank participants
To quantify the association of combined sleep behaviours and genetic susceptibility with the incidence of cardiovascular disease (CVD).Methods and resultsThis study included 385 292 participants initially free of CVD from UK Biobank. We newly created a healthy sleep score according to five sleep factors and defined the low-risk groups as follows: early chronotype, sleep 7–8 h per… Continue reading Sleep patterns, genetic susceptibility, and incident cardiovascular disease: a prospective study of 385 292 UK biobank participants
A thermometer circuit for hot temperature adjusts Drosophila behavior to persistent heat
Small poikilotherms such as the fruit fly Drosophila depend on absolute temperature measurements to identify external conditions that are above (hot) or below (cold) their preferred range and to react accordingly. Hot and cold temperatures have a different impact on fly activity and sleep, but the circuits and mechanisms that adjust behavior to specific thermal conditions are… Continue reading A thermometer circuit for hot temperature adjusts Drosophila behavior to persistent heat
Single-Channel EEG Features Reveal an Association With Cognitive Decline in Seniors Performing Auditory Cognitive Assessment
Background: Cognitive decline remains highly underdiagnosed despite efforts to find novel cognitive biomarkers. Electroencephalography (EEG) features based on machine-learning (ML) may offer a non-invasive, low-cost approach for identifying cognitive decline. However, most studies use cumbersome multi-electrode systems. This study aims to evaluate the ability to assess cognitive states using machine learning (ML)-based EEG features extracted from… Continue reading Single-Channel EEG Features Reveal an Association With Cognitive Decline in Seniors Performing Auditory Cognitive Assessment
Covid-19: Regulators warn that rare Guillain-Barré cases may link to J&J and AstraZeneca vaccines
Rapid Response:Autoimmune damage to the nerves following Covid vaccines: EMA issued warning to patients and healthcare professionalsDear EditorEMA recently investigated the cases of Guillain-Barre syndrome (GBS) following Covid vaccine AstraZeneca (AZ) and have issued a warning to raise awareness of healthcare professionals and the public about GBS cases following Covid vaccinations and recommended revising the… Continue reading Covid-19: Regulators warn that rare Guillain-Barré cases may link to J&J and AstraZeneca vaccines
