• What are the Most Accurate Non-invasive Techniques for Measuring Liver Fibrosis and Steatosis?

What are the Most Accurate Non-invasive Techniques for Measuring Liver Fibrosis and Steatosis?

Magnetic resonance elastography (MRE) is more accurate than transient elastography (TE) in identifying liver fibrosis of stage 1 or more, researchers report in the February issue of Gastroenterology, using biopsy analysis as the standard. They also show that MRI-based proton density fat fraction (MRI-PDFF) analysis is more accurate than TE-based

  • Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Consumption of red meat, saturated fat, and cholesterol increase risk for gallstone-related acute pancreatitis, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Dietary fiber protects against acute pancreatitis—related and unrelated to gallstones—whereas coffee protects against acute pancreatitis not associated with gallstones, the study of thousands of patients

Is it Safe to Undergo Endoscopy During Pregnancy?

Endoscopy during pregnancy is associated with slight increases in risk of preterm birth and small for gestational age, but not congenital malformation or stillbirth, researchers report in a nationwide population-based cohort study published in the February issue of Gastroenterology. However, the authors believe the small increase in risk to be

  • Can Vitamin D Affect Risk of Ulcerative Colitis Relapse?

Can Vitamin D Affect Risk of Ulcerative Colitis Relapse?

Serum levels of vitamin D of 35 ng/mL or less in patients with ulcerative colitis (UC) in clinical remission are associated with disease relapse, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Increasing patients’ levels of vitamin D might reduce their risk for UC relapse. Vitamin D

Video: Screening Breath Compounds to Identify Patients With Barrett’s Esophagus

Researchers can identify patients with Barrett’s esophagus (BE) based on profiles of exhaled volatile organic compounds measured with an electronic nose device. This tool, described in the January issue of Gastroenterology, provides a portable, accessible, and widely acceptable tool for screening and surveillance for BE in patients with gastroesophageal reflux

  • A Minimally Invasive Endoscopic Procedure Instead of Bariatric Surgery?

A Minimally Invasive Endoscopic Procedure Instead of Bariatric Surgery?

Endoscopic sleeve gastroplasty (ESG) delays gastric emptying, induces early satiation, and significantly reduces body weight, researchers report in the January issue of Clinical Gastroenterology and Hepatology. ESG could therefore be an alternative to bariatric surgery for some patients with obesity. Although bariatric surgery is the most effective therapy for obesity,

  • How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

Researchers have developed a patient-derived cell line-based model to study how intratumor heterogeneity affects sensitivity of hepatocellular carcinoma (HCC) to different therapeutic agents, reported in the January issue of Gastroenterology. HCCs have a large amount of genetic heterogeneity within each tumor, making them difficult to treat. Multiple regions of tumors

  • Hepatosplenic Lesions from Cat Scratch Disease

Hepatosplenic Lesions from Cat Scratch Disease

Researchers describe an unusual case of cat scratch disease, with hepatosplenic involvement, in the January 2017 issue of Clinical Gastroenterology and Hepatology. Sean K. Verma et al report on a 28-year-old man with no past medical history presented with fevers, chills, abdominal pain, night sweats, 3 weeks of weight loss,

  • How Does Transforming Growth Factor beta Suppress Colorectal Tumor Development?

How Does Transforming Growth Factor beta Suppress Colorectal Tumor Development?

Researchers review the mechanisms by which loss of transforming growth factor beta (TGFB) proteins contribute to development and progression of colorectal cancer in the January 2017 issue of Gastroenterology. Development and progression of colorectal cancer involve loss of tumor suppressor proteins, including transforming growth factor beta (TGFB) family members. In colon

  • Can a Smartphone App Monitor IBD Activity?

Can a Smartphone App Monitor IBD Activity?

Researchers have developed a mobile health index for remote monitoring of patients with inflammatory bowel diseases (IBD) that could be incorporated into a smartphone app. These findings are reported in the December issue of Clinical Gastroenterology and Hepatology. The shift from symptom-oriented to prevention-oriented care delivery has accelerated the development of

  • How Does Cigarette Smoking Lead to Chronic Pancreatitis?

How Does Cigarette Smoking Lead to Chronic Pancreatitis?

Aryl hydrocarbons in cigarette smoke activate an immune response that promotes pancreatic fibrosis and contributes to pancreatitis, researchers report in the December issue of Gastroenterology. The authors show that constituents of tobacco smoke activate signaling via the aryl hydrocarbon receptor (AHR) to induce T-cell production of interleukin 22 (IL22), activating

  • Do Relatives of Patients With IBD Also Have Intestinal Dysbiosis?

Do Relatives of Patients With IBD Also Have Intestinal Dysbiosis?

The intestinal microbiota of many healthy, first-degree relatives of patients with inflammatory bowel diseases (IBD) is dysbiotic, signifying a pre-disease state, low-level inflammation, and susceptibility to IBD, researchers report in the November issue of Cellular and Molecular Gastroenterology and Hepatology. Changes in the intestinal microbiome are involved in the pathogenesis

  • Can Yoga Reduce Symptoms of IBS?

Can Yoga Reduce Symptoms of IBS?

Yoga might be a feasible and safe adjunct treatment for irritable bowel syndrome (IBS), a systematic review shows in the December issue of Clinical Gastroenterology and Hepatology. The review found evidence for beneficial effects of yoga on gastrointestinal (GI) symptoms, quality of life, and anxiety, although further studies are needed. IBS is

  • How Does Inflammation Lead to Anemia?

How Does Inflammation Lead to Anemia?

Researchers report a mechanism by which inflammation contributes to development of anemia in the November issue of Gastroenterology. The process involves increased liver expression of a microRNA that reduces production of erythropoietin in kidney. Strategies to block this miRNA might help prevent anemia in patients with chronic inflammation. Anemia is associated
