Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA was detected in faeces of patients with COVID-19, the activity and infectivity of the virus in the GI tract during disease course is largely unknown. We investigated temporal transcriptional activity of SARS-CoV-2 and its association with longitudinal faecal microbiome alterations in patients with COVID-19.. Seven (46.7%)… Continue reading Depicting #SARS-CoV-2 faecal viral activity in association with #gut microbiota composition in patients with COVID-19

Natural history of acute #kidney disease in patients with #cirrhosis
In 2012, KDIGO group proposed new definitions for Acute Kidney Injury (AKI), Acute Kidney Disease (AKD) and Chronic Kidney Disease (CKD). According to the definition adapted by the International Club of Ascites (ICA), AKI has been extensively investigated in patients with cirrhosis. On the contrary, there are currently no data on the epidemiology and clinical… Continue reading Natural history of acute #kidney disease in patients with #cirrhosis
Warmth Prevents #Bone Loss Through the Gut #Microbiota
Osteoporosis is the most prevalent metabolic bone disease, characterized by low bone mass and microarchitectural deterioration. Here, we show that warmth exposure (34°C) protects against ovariectomy-induced bone loss by increasing trabecular bone volume, connectivity density, and thickness, leading to improved biomechanical bone strength in adult female, as well as in young male mice. Transplantation of… Continue reading Warmth Prevents #Bone Loss Through the Gut #Microbiota
Hepatic decompensation in #cirrhotic patients receiving antiviral therapy for chronic #hepatitis B
It is unclear if anti-hepatitis B virus (HBV) treatment can eliminate incident hepatic decompensation. Here we report the incidence and predictors of hepatic decompensation among cirrhotic patients receiving antiviral therapy for chronic hepatitis B.. ..818 patients (mean age, 54.9 years; 519 male [63.4%]) were included in the final analysis. During a mean follow-up of 58.1… Continue reading Hepatic decompensation in #cirrhotic patients receiving antiviral therapy for chronic #hepatitis B
#Obesity Has a Stronger Relationship with Colorectal #Cancer in Postmenopausal Women Than Premenopausal Women
Background: To examine the relationship between obesity measured by waist circumference (WC) and body mass index (BMI) and the incidence of colorectal cancer (CRC) in premenopausal and postmenopausal women. Methods: A total of 1,418,180 premenopausal and 4,854,187 postmenopausal women without cancer at baseline and aged over 40 were identified using the Korean National Health Insurance… Continue reading #Obesity Has a Stronger Relationship with Colorectal #Cancer in Postmenopausal Women Than Premenopausal Women
Heterogeneity and clonal relationships of adaptive immune cells in #ulcerative colitis revealed by single-cell analyses
Inflammatory bowel disease (IBD) encompasses a spectrum of gastrointestinal disorders driven by dysregulated immune responses against gut microbiota. We integrated single-cell RNA and antigen receptor sequencing to elucidate key components, cellular states, and clonal relationships of the peripheral and gastrointestinal mucosal immune systems in health and ulcerative colitis (UC). UC was associated with an increase… Continue reading Heterogeneity and clonal relationships of adaptive immune cells in #ulcerative colitis revealed by single-cell analyses
Vitamin #D receptor is overexpressed in the duodenum of patients with #irritable bowel syndrome
Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders and bile acids are thought to be associated with the pathogenesis of IBS. Bile acid receptors are expressed on intestinal epithelial cells. However, no study has assessed bile acid receptor proteins in IBS. Therefore, we examined the intestinal mucosal expression of bile… Continue reading Vitamin #D receptor is overexpressed in the duodenum of patients with #irritable bowel syndrome
Efficacy and safety of gastrointestinal #bleeding prophylaxis in critically #ill patients: an updated systematic review and network meta-analysis of randomized trials
Motivated by a new randomized trial (the PEPTIC trial) that raised the issue of an increase in mortality with proton pump inhibitors (PPIs) relative to histamine-2 receptor antagonists (H2RAs), we updated our prior systematic review and network meta-analysis (NMA) addressing the impact of pharmacological gastrointestinal bleeding prophylaxis in critically ill patients. Seventy-four trials enrolling 39… Continue reading Efficacy and safety of gastrointestinal #bleeding prophylaxis in critically #ill patients: an updated systematic review and network meta-analysis of randomized trials
Vitamin #D for treatment of non‐alcoholic #fatty liver disease detected by transient elastography: A randomized, double‐blind, placebo‐controlled trial
To evaluate the effects of vitamin D on transient elastography (TE, FibroScan) indices of liver steatosis (controlled attenuation parameter [CAP]) and fibrosis (liver stiffness measurement [LSM]) in adults with non‐alcoholic fatty liver disease (NAFLD).. ..Both CAP and LSM gradually decreased in vitamin D‐treated patients and slightly increased in the placebo arm. Vitamin D was superior… Continue reading Vitamin #D for treatment of non‐alcoholic #fatty liver disease detected by transient elastography: A randomized, double‐blind, placebo‐controlled trial
