Background and ObjectivesTerazosin, doxazosin, and alfuzosin (Tz/Dz/Az) are α-1 adrenergic receptor antagonists that also bind to and activate a key adenosine triphosphate (ATP)–producing enzyme in glycolysis. It is hypothesized that the increase in energy availability in the brain may slow or prevent neurodegeneration, potentially by reducing the accumulation of alpha-synuclein. Recent work has suggested a… Continue reading Association of #Terazosin, #Doxazosin, or #Alfuzosin Use and Risk of #Dementia With Lewy Bodies in Men

#Stress -resilience impacts psychological wellbeing as evidenced by brain–gut #microbiome interactions
The brain–gut microbiome (BGM) system plays an influential role on mental health. We characterized BGM patterns related to resilience using fecal samples and multimodal magnetic resonance imaging. Data integration analysis using latent components showed that the high-resilience phenotype was associated with lower depression and anxiety symptoms, higher frequency of bacterial transcriptomes (related to environmental adaptation,… Continue reading #Stress -resilience impacts psychological wellbeing as evidenced by brain–gut #microbiome interactions
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
Premenopausal bilateral #oophorectomy and #brain white matter brain integrity in later-life
INTRODUCTIONPremenopausal bilateral oophorectomy (PBO) is associated with later-life cognition, but the underlying brain changes remain unclear. We assessed the impact of PBO and PBO age on white matter integrity.METHODSFemale participants with regional diffusion tensor imaging (DTI) metrics of fractional anisotropy (FA) and mean diffusivity (MD) were included (22 with PBO < 40 years; 43 with PBO 40-45… Continue reading Premenopausal bilateral #oophorectomy and #brain white matter brain integrity in later-life
Self-administered #mindfulness interventions reduce #stress in a large, randomized controlled multi-site study
Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ; retrospective registration at ClinicalTrials.gov NCT06308744) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single,… Continue reading Self-administered #mindfulness interventions reduce #stress in a large, randomized controlled multi-site study
National, regional, and global trends in insufficient #physical activity among adults from 2000 to 2022: a pooled analysis of 507 population-based surveys with 5·7 million participants
BackgroundInsufficient physical activity increases the risk of non-communicable diseases, poor physical and cognitive function, weight gain, and mental ill-health. Global prevalence of adult insufficient physical activity was last published for 2016, with limited trend data. We aimed to estimate the prevalence of insufficient physical activity for 197 countries and territories, from 2000 to 2022.MethodsWe collated… Continue reading National, regional, and global trends in insufficient #physical activity among adults from 2000 to 2022: a pooled analysis of 507 population-based surveys with 5·7 million participants
Effectiveness and cost-effectiveness of an individualised, progressive #walking and education intervention for the prevention of low back #pain recurrence in Australia (WalkBack): a randomised controlled trial
BackgroundRecurrence of low back pain is common and a substantial contributor to the disease and economic burden of low back pain. Exercise is recommended to prevent recurrence, but the effectiveness and cost-effectiveness of an accessible and low-cost intervention, such as walking, is yet to be established. We aimed to investigate the clinical effectiveness and cost-effectiveness… Continue reading Effectiveness and cost-effectiveness of an individualised, progressive #walking and education intervention for the prevention of low back #pain recurrence in Australia (WalkBack): a randomised controlled trial
Impact of #lifestyle moderate-to-vigorous #physical activity timing on #glycemic control in sedentary adults with #overweight/obesity and metabolic impairments
ObjectiveModerate-to-vigorous physical activity (MVPA) improves glucose levels; however, whether its timing affects daily glycemic control remains unclear. This study aims to investigate the impact of lifestyle MVPA timing on daily glycemic control in sedentary adults with overweight/obesity and metabolic impairments.MethodsA total of 186 adults (50% women; age, 46.8 [SD 6.2] years) with overweight/obesity (BMI, 32.9… Continue reading Impact of #lifestyle moderate-to-vigorous #physical activity timing on #glycemic control in sedentary adults with #overweight/obesity and metabolic impairments
A Systematic REVIEW of #Autopsy findings in deaths after #covid-19 vaccination
Highlights•We found that 73.9% of deaths were directly due to or significantly contributed to by COVID-19 vaccination.•Our data suggest a high likelihood of a causal link between COVID-19 vaccination and death.•These findings indicate the urgent need to elucidate the pathophysiologic mechanisms of death with the goal of risk stratification and avoidance of death for the… Continue reading A Systematic REVIEW of #Autopsy findings in deaths after #covid-19 vaccination
