Physical activity relates to reduced dementia risk, though the cellular and molecular mechanisms are unknown. We translated animal and in-vitro studies demonstrating a causal link between physical activity and microglial homeostasis into humans. Decedents from Rush MAP completed actigraphy monitoring (average daily activity) and cognitive evaluation in life, and neuropathological examination at autopsy. Brain tissue… Continue reading Microglial correlates of late life physical activity: Relationship with synaptic and cognitive aging in older adults

Metabolic Syndrome-Related Hyperuricemia is Associated with a Poorer Prognosis in Patients with Colorectal Cancer: A Multicenter Retrospective Study
Hyperuricemia and metabolic syndrome (MetS) have been shown to correlate with prognosis in patients with malignant tumors. The present study evaluated the relationship between preoperative hyperuricemia and MetS in colorectal cancer (CRC) patients and analyzed the effect of this combination on prognosis within 5 years. Patients and Methods: The study enrolled patients who had undergone… Continue reading Metabolic Syndrome-Related Hyperuricemia is Associated with a Poorer Prognosis in Patients with Colorectal Cancer: A Multicenter Retrospective Study
Higher Coffee Consumption Is Associated With Slower Cognitive Decline and Less Cerebral Aβ-Amyloid Accumulation Over 126 Months: Data From the Australian Imaging, Biomarkers, and Lifestyle Study
Worldwide, coffee is one of the most popular beverages consumed. Several studies have suggested a protective role of coffee, including reduced risk of Alzheimer’s disease (AD). However, there is limited longitudinal data from cohorts of older adults reporting associations of coffee intake with cognitive decline, in distinct domains, and investigating the neuropathological mechanisms underpinning any… Continue reading Higher Coffee Consumption Is Associated With Slower Cognitive Decline and Less Cerebral Aβ-Amyloid Accumulation Over 126 Months: Data From the Australian Imaging, Biomarkers, and Lifestyle Study
Face masks: benefits and risks during the COVID-19 crisis
The German government has made it mandatory to wear respiratory masks covering mouth and nose (MNC) as an effective strategy to fight SARS-CoV-2 infections. In many countries, this directive has been extended on shopping malls or public transportation. The aim of this paper is to critically analyze the statutory regulation to wear protective masks during… Continue reading Face masks: benefits and risks during the COVID-19 crisis
Autocrine vitamin #D signaling switches off pro-inflammatory programs of TH1 cells
The molecular mechanisms governing orderly shutdown and retraction of CD4+ type 1 helper T (TH1) cell responses remain poorly understood. Here we show that complement triggers contraction of TH1 responses by inducing intrinsic expression of the vitamin D (VitD) receptor and the VitD-activating enzyme CYP27B1, permitting T cells to both activate and respond to VitD.… Continue reading Autocrine vitamin #D signaling switches off pro-inflammatory programs of TH1 cells
Air pollution and endocrine disruptors induce human microbiome imbalances: A systematic review of recent evidence and possible biological mechanisms
Highlights•Environmental pollution could affect diversity of resident microbiota. •Environmental pollution could affect abundance of resident microbiota. •Studies suggest air pollution increases the abundance of streptococcus. •Studies suggest air pollution increases the abundance of veillionellales. •Scarcity of studies precludes observing consistent trends for other microbiota. AbstractA rich body of literature indicates that environmental factors interact with… Continue reading Air pollution and endocrine disruptors induce human microbiome imbalances: A systematic review of recent evidence and possible biological mechanisms
The role of different lipid measures for incident hypertension during more than 12 years follow-up: Tehran Lipid and Glucose Study
To examine the associations of different lipid measures and related indices with incident hypertension during a median follow-up of 12.89 years. Fasting levels of total cholesterol (TC), triglycerides (TG), high and low density lipoprotein cholesterol (HDL-C and LDL-C, respectively), and related indices (TC/HDL-C and TG/HDL-C) were determined in 7335 Iranian adults (men=3270) free of hypertension,… Continue reading The role of different lipid measures for incident hypertension during more than 12 years follow-up: Tehran Lipid and Glucose Study
The epidemiological relevance of the COVID-19-vaccinated population is increasing
High COVID-19 vaccination rates were expected to reduce transmission of SARS-CoV-2 in populations by reducing the number of possible sources for transmission and thereby to reduce the burden of COVID-19 disease. Recent data, however, indicate that the epidemiological relevance of COVID-19 vaccinated individuals is increasing. In the UK it was described that secondary attack rates… Continue reading The epidemiological relevance of the COVID-19-vaccinated population is increasing
Elapsed time since BNT162b2 vaccine and risk of SARS-CoV-2 infection: test negative design study
To determine whether time elapsed since the second injection of the Pfizer-BioNTech BNT162b2 mRNA vaccine was significantly associated with the risk of covid-19 infection after vaccination in people who received two vaccine injections. Design Test negative design study. Setting Electronic health records of a large state mandated healthcare organisation, Israel. Participants Adults aged ≥18 years… Continue reading Elapsed time since BNT162b2 vaccine and risk of SARS-CoV-2 infection: test negative design study
