Can Learning to Control Thoracic Muscle Activity Reduce Abdominal Distension?

A behavioral intervention designed to increase the postural tone of the abdomino-thoracic wall is effective treatment for abdominal distention of no detectable cause, researchers report in a randomized controlled trial published in the December issue of Clinical Gastroeneterology and Hepatology. Abdominal distension is one of the most common complaints among patients seeking

  • 3-D Imaging of T-cell Localization in Inflamed Colon Tissues

3-D Imaging of T-cell Localization in Inflamed Colon Tissues

Light sheet fluorescence microscopy (LSFM) provides accurate 3-dimensional images of inflammed intestine of mice with colitis, researchers show in a Gastroenterology in Motion article and video in the October issue of Gastroenterology. The authors demonstrate use of the technology to analyze migration of human T cells in colons of mice with colitis. Improved techniques are

Video: EUS Detection of Early-stage Gastric Cancer in a Patient with FAP

Endoscopic ultrasound (EUS) can detect early-stage gastric cancers developing beneath or within the mucosa that are not visualized by endoscopy in patients with familial adenomatous polyposis (FAP). Researchers report these findings along with a video in the August issue of Gastroenterology. FAP is a hereditary colorectal cancer syndrome characterized by colorectal polyps and colorectal cancer. Patients

  • Bioinformatic Search Identifies Tapeworm Drug for Treatment of Hepatocellular Carcinoma

Bioinformatic Search Identifies Tapeworm Drug for Treatment of Hepatocellular Carcinoma

In a bioinformatic search for agents that alter the hepatocellular carcinoma (HCC)-specific gene expression pattern, researchers identified the anthelmintic drug niclosamide as a potential anti-tumor agent, described in the June issue of Gastroenterology. Niclosamide and its ethanolamine salt (NEN), with greater bioavailability, slowed growth of genetically induced liver tumors and

  • FUSE Outperforms Forward-viewing Colonoscopy in Detecting Dysplasia in Patients With IBD

FUSE Outperforms Forward-viewing Colonoscopy in Detecting Dysplasia in Patients With IBD

The panoramic views obtained with full-spectrum endoscopy (FUSE) increase the number of dysplastic lesions detected in the colon, compared with conventional forward-viewing colonoscopy, researchers report in the May issue of Gastroenterology. Inflammatory bowel diseases (IBDs) increase the risk of colorectal cancer. Surveillance colonoscopy with chromoendoscopy is recommended, but conventional forward-viewing colonoscopy

  • What is the Incidence of Achalasia?

What is the Incidence of Achalasia?

The incidence of achalasia is at least twice as high as previously believed, 2 studies (one from Chicago, the other from Australia) show in the March issue of Clinical Gastroenterology and Hepatology. Achalasia is characterized by dysphagia, regurgitation of undigested food, and chest pain. Patients lose weight due to the

  • What is the Active Ingredient in FMT for CDI?

What is the Active Ingredient in FMT for CDI?

Sterile fecal filtrates—containing bacterial debris, proteins, antimicrobial compounds, metabolic products, and microbial DNA, rather than intact microorganisms—appear to be effective for treatment of recurrent Clostridium difficile infection (CDI), researchers report in the March issue of Gastroenterology. Fecal microbiota transplantation (FMT) is an effective therapy of recurrent CDI—a single treatment resolves

  • A New Pathway for Transmitting HBV DNA?

A New Pathway for Transmitting HBV DNA?

Extracellular vesicles carry HBV DNA as cargo that can be transmitted to other hepatocytes, researchers report in the March issue of Cellular and Molecular Gastroenterology and Hepatology. Their findings identify an antibody-neutralization–resistant route of HBV infection. Approximately 350 million people are chronically infected by HBV worldwide, and some of these

  • 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

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
