Alterations in the intestinal microbiota contribute to the pathogenesis of various cardiovascular disorders, but how they affect the development of Kawasaki disease (KD) an acute pediatric vasculitis, remains unclear.METHODS:We used the Lactobacillus casei cell wall extract (LCWE) murine model of KD vasculitis to assess the contribution of the intestinal microbiota to the development of vascular… Continue reading Intestinal #Microbiota Contributes to the Development of #Cardiovascular Inflammation and Vasculitis in Mice
#Probiotics reduce negative #mood over time: the value of daily self-reports in detecting effects
The burgeoning field of the microbiome–gut–brain axis has inspired research into how the gut microbiome can affect human emotion. Probiotics offer ways to investigate microbial-based interventions but results have been mixed, with more evidence of beneficial effects in clinically depressed patients. Using a randomised, double-blind, placebo-controlled design in 88 healthy volunteers, we conduct a comprehensive… Continue reading #Probiotics reduce negative #mood over time: the value of daily self-reports in detecting effects
#Skin damage signals mediate #allergic sensitization to spatially unlinked antigen
Our current understanding of immunity to pathogens suggests that anatomic coupling of antigens with danger signals is a required feature for the formation of immune memory. However, in the context of pathogen-independent inflammation, the stringency of this anatomical coupling is unclear. Here, we demonstrate that multiple modes of skin injury were sufficient to induce a… Continue reading #Skin damage signals mediate #allergic sensitization to spatially unlinked antigen
GLP-1RA and SGLT2i Medications for Type 2 #Diabetes and #Alzheimer Disease and Related Dementias
Importance The association between glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT2is) and risk of Alzheimer disease and related dementias (ADRD) remains to be confirmed.Objective To assess the risk of ADRD associated with GLP-1RAs and SGLT2is in people with type 2 diabetes (T2D).Design, Setting, and Participants This target trial emulation study used electronic… Continue reading GLP-1RA and SGLT2i Medications for Type 2 #Diabetes and #Alzheimer Disease and Related Dementias
Sociodemographic #biases in medical decision making by large language models
Large language models (LLMs) show promise in healthcare, but concerns remain that they may produce medically unjustified clinical care recommendations reflecting the influence of patients’ sociodemographic characteristics. We evaluated nine LLMs, analyzing over 1.7 million model-generated outputs from 1,000 emergency department cases (500 real and 500 synthetic). Each case was presented in 32 variations (31… Continue reading Sociodemographic #biases in medical decision making by large language models
Immune and metabolic effects of African heritage #diets versus Western diets in men: a randomized controlled trial
African heritage diets are increasingly being replaced by Western-style dietary patterns because of urbanization, economic development, increased access to processed foods, globalization and changing social norms. The health consequences of this nutrition transition are not well understood. We conducted a randomized controlled trial in the Kilimanjaro region in Northern Tanzania to investigate the immune and… Continue reading Immune and metabolic effects of African heritage #diets versus Western diets in men: a randomized controlled trial
Share onGlobal Effect of #Cardiovascular Risk Factors on Lifetime Estimates
Five risk factors account for approximately 50% of the global burden of cardiovascular disease. How the presence or absence of classic risk factors affects lifetime estimates of cardiovascular disease and death from any cause remains unclear.MethodsWe harmonized individual-level data from 2,078,948 participants across 133 cohorts, 39 countries, and 6 continents. Lifetime risk of cardiovascular disease… Continue reading Share onGlobal Effect of #Cardiovascular Risk Factors on Lifetime Estimates
Marital status and risk of #dementia over 18 years: Surprising findings from the National Alzheimer’s Coordinating Center
Marital status is a potential risk/protective factor for adverse health outcomes. This study tested whether marital status was associated with dementia risk in older adults.METHODSParticipants (N = 24,107; Meanage = 71.79) were from the National Alzheimer's Coordinating Center. Cox regressions tested the association between baseline marital status and clinically ascertained dementia over up to 18… Continue reading Marital status and risk of #dementia over 18 years: Surprising findings from the National Alzheimer’s Coordinating Center
Non-caloric #sweetener effects on brain appetite regulation in individuals across varying body #weights
Sucralose, a widely used non-caloric sweetener, provides sweet taste without calories. Some studies suggest that non-caloric sweeteners stimulate appetite, possibly owing to the delivery of a sweet taste without the post-ingestive metabolic signals that normally communicate with the hypothalamus to suppress hunger. In a randomized crossover trial (ClinicalTrials.gov identifier: NCT02945475), 75 young adults (healthy weight,… Continue reading Non-caloric #sweetener effects on brain appetite regulation in individuals across varying body #weights
