Insight into associations between the gut microbiome with metabolism and aging is crucial for tailoring interventions to promote healthy longevity. In a discovery cohort of 10,207 individuals aged 40–93 years, we used 21 metabolic parameters to classify individuals into five clusters, termed metabolic multimorbidity clusters (MCs), that represent different metabolic subphenotypes. Compared to the cluster classified… Continue reading Divergent age-associated and metabolism-associated gut #microbiome signatures modulate #cardiovascular disease risk

Acute Vigorous #Exercise Decreases Subsequent Non-Exercise Physical Activity and Body Temperature Linked to #Weight Gain
Purpose Exercise benefits the body and mind, but its weight loss effect is less than generally expected. Although this phenomenon is likely due to an exercise intensity-dependent decrease in non-exercise physical activity (NEPA), resulting in a decrease in non-exercise activity thermogenesis, the underlying mechanisms and effects of exercise intensity remain unknown. Here we show that acute… Continue reading Acute Vigorous #Exercise Decreases Subsequent Non-Exercise Physical Activity and Body Temperature Linked to #Weight Gain
Mitochondrial ACSS1-K635 acetylation knock-in mice exhibit altered metabolism, cell senescence, and nonalcoholic fatty #liver disease
Acetyl-CoA synthetase short-chain family member 1 (ACSS1) uses acetate to generate mitochondrial acetyl-CoA and is regulated by deacetylation by sirtuin 3. We generated an ACSS1-acetylation (Ac) mimic mouse, where lysine-635 was mutated to glutamine (K635Q). Male Acss1K635Q/K635Q mice were smaller with higher metabolic rate and blood acetate and decreased liver/serum ATP and lactate levels. After a 48-hour… Continue reading Mitochondrial ACSS1-K635 acetylation knock-in mice exhibit altered metabolism, cell senescence, and nonalcoholic fatty #liver disease
Association between consumption of small #fish and all-cause #mortality among Japanese: the Japan Multi-Institutional Collaborative Cohort Study
Although small fish are an important source of micronutrients, the relationship between their intake and mortality remains unclear. This study aimed to clarify the association between intake of small fish and all-cause and cause-specific mortality.Design:We used the data from a cohort study in Japan. The frequency of the intake of small fish was assessed using… Continue reading Association between consumption of small #fish and all-cause #mortality among Japanese: the Japan Multi-Institutional Collaborative Cohort Study
#Atherosclerotic #Cardiovascular Disease Risk Estimates Using the Predicting Risk of Cardiovascular Disease Events Equations
Key PointsQuestion How do estimates of 10-year atherosclerotic cardiovascular disease (ASCVD) risk and recommendations for primary prevention statin therapy differ between the 2023 American Heart Association (AHA) Predicting Risk of Cardiovascular Disease Events (PREVENT) equations and the 2013 AHA/American College of Cardiology pooled cohort equations (PCEs)?Findings In this cross-sectional study of 3785 adults aged 40 to 75… Continue reading #Atherosclerotic #Cardiovascular Disease Risk Estimates Using the Predicting Risk of Cardiovascular Disease Events Equations
Effect of timed dosing of usual #antihypertensives according to patient chronotype on #cardiovascular outcomes: the Chronotype sub-study cohort of the Treatment in Morning versus Evening (TIME) study
BackgroundTiming drug administration to endogenous circadian rhythms may enhance treatment efficacy. In the Chronotype sub-study of the Treatment in Morning versus Evening (TIME) clinical trial we examined whether timing of usual antihypertensive medications according to patient chronotype (a behavioural marker of personal circadian rhythm) may influence clinical cardiovascular outcomes.MethodsThis was a cohort sub-study of TIME,… Continue reading Effect of timed dosing of usual #antihypertensives according to patient chronotype on #cardiovascular outcomes: the Chronotype sub-study cohort of the Treatment in Morning versus Evening (TIME) study
#Cerebrovascular Effects of #Sildenafil in Small Vessel Disease: The OxHARP Trial
BACKGROUND:Vascular cognitive impairment due to cerebral small vessel disease is associated with cerebral pulsatility, white matter hypoperfusion, and reduced cerebrovascular reactivity (CVR), and is potentially improved by endothelium-targeted drugs such as cilostazol. Whether sildenafil, a phosphodiesterase-5 inhibitor, improves cerebrovascular dysfunction is unknown.METHODS:OxHARP trial (Oxford Haemodynamic Adaptation to Reduce Pulsatility) was a double-blind, randomized, placebo-controlled, 3-way… Continue reading #Cerebrovascular Effects of #Sildenafil in Small Vessel Disease: The OxHARP Trial
#Bartonella species bacteremia in association with adult #psychosis
Introduction: The potential role of pathogens, particularly vector-transmitted infectious agents, as a cause of psychosis has not been intensively investigated. We have reported a potential link between Bartonella spp. bacteremia and neuropsychiatric symptoms, including pediatric acute onset neuropsychiatric syndrome and schizophrenia. The purpose of this study was to further assess whether Bartonella spp. exposure or infection are associated with psychosis.Methods: In… Continue reading #Bartonella species bacteremia in association with adult #psychosis
Prescribed Drug Use and #Aneurysmal Subarachnoid #Hemorrhage IncidenceA Drug-Wide Association Study
Background and ObjectivesCurrent benefits of invasive intracranial aneurysm treatment to prevent aneurysmal subarachnoid hemorrhage (aSAH) rarely outweigh treatment risks. Most intracranial aneurysms thus remain untreated. Commonly prescribed drugs reducing aSAH incidence may provide leads for drug repurposing. We performed a drug-wide association study (DWAS) to systematically investigate the association between commonly prescribed drugs and aSAH… Continue reading Prescribed Drug Use and #Aneurysmal Subarachnoid #Hemorrhage IncidenceA Drug-Wide Association Study
