Patients hospitalised with COVID-19 are at risk for thrombotic events after discharge; the role of extended thromboprophylaxis in this population is unknown. MethodsIn this open-label, multicentre, randomised trial conducted at 14 centres in Brazil, patients hospitalised with COVID-19 at increased risk for venous thromboembolism (International Medical Prevention Registry on Venous Thromboembolism [IMPROVE] venous thromboembolism [VTE]… Continue reading Rivaroxaban versus no anticoagulation for post-discharge thromboprophylaxis after hospitalisation for COVID-19 (MICHELLE): an open-label, multicentre, randomised, controlled trial
Association of Physical Activity Level With Risk of Dementia in a Nationwide Cohort in Korea
Current guidelines recommend 500 to 999 metabolic equivalent (MET)–minutes per week (MET-min/wk) of regular physical activity. However, evidence regarding the association between light-intensity physical activity (LPA) and dementia in older adults is inconsistent. Objective To assess the association between physical activity and new-onset dementia, focusing on the dose-response association between physical activity and dementia and… Continue reading Association of Physical Activity Level With Risk of Dementia in a Nationwide Cohort in Korea
Are biomechanics during gait associated with the structural disease onset and progression of lower limb osteoarthritis? A systematic review and meta-analysis
To evaluate if gait biomechanics are associated with increased risk of structurally diagnosed disease onset or progression of lower limb osteoarthritis (OA). MethodA systematic review of Medline and Embase was conducted from inception to July 2021. Two reviewers independently screened records, extracted data and assessed risk of bias. Included studies reported gait biomechanics at baseline,… Continue reading Are biomechanics during gait associated with the structural disease onset and progression of lower limb osteoarthritis?

Free fatty-acid transport via CD36 drives β-oxidation-mediated hematopoietic stem cell response to infection
Acute infection is known to induce rapid expansion of hematopoietic stem cells (HSCs), but the mechanisms supporting this expansion remain incomplete. Using mouse models, we show that inducible CD36 is required for free fatty acid uptake by HSCs during acute infection, allowing the metabolic transition from glycolysis towards β-oxidation. Mechanistically, high CD36 levels promote FFA… Continue reading Free fatty-acid transport via CD36 drives β-oxidation-mediated hematopoietic stem cell response to infection
Food Insecurity is Associated with Mortality Among U.S. Adults with Nonalcoholic Fatty Liver Disease and Advanced Fibrosis
Food insecurity is a growing public health challenge in the U.S. and has been linked to nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis. However, little is known of how food insecurity impacts mortality risk and healthcare utilization (HCU) in chronic liver disease. MethodsUsing a population-based cohort study of U.S. adults (≥20 years) in the… Continue reading Food Insecurity is Associated with Mortality Among U.S. Adults with Nonalcoholic Fatty Liver Disease and Advanced Fibrosis
Global Percentage of Asymptomatic SARS-CoV-2 Infections Among the Tested Population and Individuals With Confirmed COVID-19 DiagnosisA Systematic Review and Meta-analysis
What is the percentage of asymptomatic individuals with positive test results for SARS-CoV-2 among tested individuals and those with confirmed COVID-19 diagnosis? Findings In this systematic review and meta-analysis of 95 unique studies with 29 776 306 individuals undergoing testing, the pooled percentage of asymptomatic infections was 0.25% among the tested population and 40.50% among the population… Continue reading Global Percentage of Asymptomatic SARS-CoV-2 Infections Among the Tested Population and Individuals With Confirmed COVID-19 DiagnosisA Systematic Review and Meta-analysis
Depression, anxiety, and happiness in dog owners and potential dog owners during the COVID-19 pandemic in the United States
Major life events, such as the COVID-19 pandemic, affect psychological and physiological health. Social support, or the lack thereof, can modulate these effects. The context of the COVID-19 pandemic offered a unique opportunity to better understand how dogs may provide social support for their owners and buffer heightened symptoms of stress, anxiety and depression and… Continue reading Depression, anxiety, and happiness in dog owners and potential dog owners during the COVID-19 pandemic in the United States
Striking Antibody Evasion Manifested by the Omicron Variant of SARS-CoV-2
The Omicron (B.1.1.529) variant of SARS-CoV-2 was only recently detected in southern Africa, but its subsequent spread has been extensive, both regionally and globally. It is expected to become dominant in the coming weeks, probably due to enhanced transmissibility. A striking feature of this variant is the large number of spike mutations that pose a… Continue reading Striking Antibody Evasion Manifested by the Omicron Variant of SARS-CoV-2
Liver expression of IL-22, IL-22R1 and IL-22BP in patients with chronic hepatitis C with different fibrosis stages
Highlights•Liver biopsies at stage F1 to F3 expressed more IL-22 than F0 or F4. •The number of cells expressing IL-22R1 decreased as fibrosis increased. •There was an increase in Il-22BP staining in more advanced stages of fibrosis. •IL-22 pathway may be involved in the pathophysiology of liver fibrosis. AbstractLiver fibrosis is the result of an… Continue reading Liver expression of IL-22, IL-22R1 and IL-22BP in patients with chronic hepatitis C with different fibrosis stages
