What is the Best Way to Assess Treatment Response in Patients With Achalasia?

A more accurate method to evaluate outcomes of treatment for achalasia is described in the May issue of Clinical Gastroenterology and Hepatology. The method identifies patients with good outcomes with higher levels of sensitivity (same specificity) than timed-barium esophagrams or impedance-manometry bolus transit assessments alone. Achalasia is an esophageal motor disorder

  • What are the Challenges to In Vitro Maturation of Hepatic Stem Cells?

What are the Challenges to In Vitro Maturation of Hepatic Stem Cells?

New approaches are needed to generate and maintain stable and mature adult liver cells ex vivo. In the April issue of Gastroenterology, Bart Spee and colleagues review factors that promote hepatocyte differentiation and maturation, and consider criteria for establishing whether cells derived from stem cells are fully mature hepatocytes. They discuss challenges to cell transplantation and

  • Does Pioglitazone Have the Same Effects on NASH in Patients With vs Without Diabetes?

Does Pioglitazone Have the Same Effects on NASH in Patients With vs Without Diabetes?

Patients with prediabetes and nonalcoholic steatohepatitis (NASH) benefit nearly as much from pioglitazone therapy as those with type-2 diabetes, researchers report in the April issue of Clinical Gastroenterology and Hepatology. The diabetes drug reduced fibrosis in non-diabetic patients with NASH, the clinical study found, although to a lesser extent than in patients

  • Does Drinking Coffee Increase Survival of Patients With Colorectal Cancer?

Does Drinking Coffee Increase Survival of Patients With Colorectal Cancer?

Drinking 2 or more cups of coffee per day after a diagnosis of stage I to III colorectal cancer (CRC) reduces risk of CRC-specific and all-cause mortality, researchers report in the March issue of Gastroenterology. Patients who maintain a high level of coffee consumption before and after diagnosis have even better odds for survival.

  • Surgical vs Endoscopic Treatment of T1 Esophageal Adenocarcinoma?

Surgical vs Endoscopic Treatment of T1 Esophageal Adenocarcinoma?

Endoscopic therapy of T1a esophageal adenocarcinoma (EAC) yields more quality-adjusted life years (QALYs) and is more cost effective than esophagectomy, shows a Markov model analysis published in the March issue of Clinical Gastroenterology and Hepatology. However, therapy for T1b EAC should be selected based on patients’ age and comorbidities. Although EAC has

  • Review: How Does the Tumor Stroma Contribute to Pancreatic Cancer Progression, and Can We Stop It?

Review: How Does the Tumor Stroma Contribute to Pancreatic Cancer Progression, and Can We Stop It?

Recently developed approaches for reshaping the pancreatic tumor stroma might be used in treatments for pancreatic cancer, according to a review in the March issue of Gastroenterology. The authors discuss relationships among the pancreatic tumor extracellular matrix, the vasculature, the immune system, and metabolism, and how these might be manipulated to stop pancreatic tumor

Why is Gallbladder Cancer Mortality Decreasing in Some Countries but Increasing in Others?

Deaths from gallbladder and other biliary tract cancers are decreasing in most countries, but increasing in some high-income countries following decades of decline, researchers report in the March issue of Clinical Gastroenterology and Hepatology. These emerging trends may reflect lifestyle changes, such as increases in excess body weight. Gallbladder cancer is

Developing a New Combination Treatment for HBV Infection

NVR3–778, a capsid assembly modulator, reduces serum levels of hepatitis B virus (HBV) DNA and HBV RNA in mice with humanized livers and stable HBV infection, researchers report in the February issue of Gastroenterology. The combination of NVR3–778 and interferon prevented viral replication and HBV RNA particle production to a greater extent than

  • What Happens When Patients With Crohn’s Disease in Remission Stop Taking Infliximab?

What Happens When Patients With Crohn’s Disease in Remission Stop Taking Infliximab?

When patients with Crohn’s disease in sustained remission stopped taking infliximab for a median 7 years, almost one fifth did not require retreatment or have a major complication, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Fewer than one fifth of patients required surgery or developed a complex perianal fistula. Increasing numbers of patients

  • VIDEO: Non-invasive Detection of Early- and Late-Stage PDAC

VIDEO: Non-invasive Detection of Early- and Late-Stage PDAC

Specific patterns of volatile organic compounds (VOCs) in urine samples can identify patients with pancreatic ductal adenocarcinoma (PDAC), researchers report in the February issue of Gastroenterology. The noninvasive technology, based on ion mobility spectrometry, can be used to discriminate between healthy individuals vs individuals with early- or advanced-stage cancer. VOCs are metabolic products of microbes that can
