As plant-based diets gain traction, interest in their impacts on the gut microbiome is growing. However, little is known about diet-pattern-specific metagenomic profiles across populations. Here we considered 21,561 individuals spanning 5 independent, multinational, human cohorts to map how differences in diet pattern (omnivore, vegetarian and vegan) are reflected in gut microbiomes. Microbial profiles distinguished… Continue reading Gut #microbiome signatures of vegan, vegetarian and omnivore diets and associated health outcomes across 21,561 individuals

The Neurologist’s Role in Promoting #Brain Health
Neurologic conditions are a leading cause of morbidity and mortality within the United States and worldwide. Brain health is a global concern, and the American Academy of Neurology's Brain Health Initiative promises to drive progress in this field over the next decades. Neurologists with detailed training and insight into brain function are uniquely positioned to… Continue reading The Neurologist’s Role in Promoting #Brain Health
The Association of Regular #Dog Walking with Mobility, #Falls and Fear of Falling in Later Life
BackgroundIt has been suggested that dog walking may protect against falls and mobility problems in later life, but little work to date has examined this.The aim of this study was to assess if regular dog walking was associated with reduced likelihood of falls, fear of falling and mobility problems in a large cohort of community-dwelling… Continue reading The Association of Regular #Dog Walking with Mobility, #Falls and Fear of Falling in Later Life
The physicochemical properties of #lipopolysaccharide chemotypes regulate activation of the contact pathway of blood coagulation
Lipopolysaccharide (LPS) is the primary pathogenic factor in Gram-negative sepsis. While the presence of LPS in the bloodstream during infection is associated with disseminated intravascular coagulation, the mechanistic link between LPS and blood coagulation activation remains ill-defined. The contact pathway of coagulation—a series of biochemical reactions that initiates blood clotting when plasma factors XII (FXII)… Continue reading The physicochemical properties of #lipopolysaccharide chemotypes regulate activation of the contact pathway of blood coagulation
#Retinal vascular fingerprints predict incident #stroke: findings from the UK Biobank cohort study
Objective To investigate the associations between a comprehensive set of retinal vascular parameters and incident stroke to unveil new associations and explore its predictive power for stroke risk.Methods Retinal vascular parameters were extracted from the UK Biobank fundus images using the Retina-based Microvascular Health Assessment System. We used Cox regression analysis, adjusted for traditional risk… Continue reading #Retinal vascular fingerprints predict incident #stroke: findings from the UK Biobank cohort study
Definition and diagnostic criteria of clinical #obesity
Current BMI-based measures of obesity can both underestimate and overestimate adiposity and provide inadequate information about health at the individual level, which undermines medically-sound approaches to health care and policy. This Commission sought to define clinical obesity as a condition of illness that, akin to the notion of chronic disease in other medical specialties, directly… Continue reading Definition and diagnostic criteria of clinical #obesity
Awakening not associated with an increased rate of #cortisol secretion
Cortisol is released upon activation of the hypothalamic–pituitary–adrenal axis, varies across the day, possesses an underlying diurnal rhythm and is responsive to stressors. The endogenous circadian peak of cortisol occurs in the morning, and increases in cortisol observed post-awakening have been named the cortisol awakening response (CAR) based on the belief that the act of… Continue reading Awakening not associated with an increased rate of #cortisol secretion
Defining ortholog-specific UHRF1 inhibition by STELLA for #cancer therapy
UHRF1 maintains DNA methylation by recruiting DNA methyltransferases to chromatin. In mouse, these dynamics are potently antagonized by a natural UHRF1 inhibitory protein STELLA, while the comparable effects of its human ortholog are insufficiently characterized, especially in cancer cells. Herein, we demonstrate that human STELLA (hSTELLA) is inadequate, while mouse STELLA (mSTELLA) is fully proficient… Continue reading Defining ortholog-specific UHRF1 inhibition by STELLA for #cancer therapy
High Density #Lipoproteins Associate with Age-Related #Macular Degeneration in the All of Us Research Program
OBJECTIVEExtracellular lipoprotein aggregation is a critical event in AMD pathogenesis. In this study, we sought to analyze associations between clinical and genetic-based factors related to lipoprotein metabolism and risk for age-related macular degeneration (AMD) in the All of Us research program.DESIGNCross-sectional retrospective data analysis.SUBJECTS5028 healthy and 2328 AMD patients from All of Us.METHODSParticipants with and… Continue reading High Density #Lipoproteins Associate with Age-Related #Macular Degeneration in the All of Us Research Program
