Patient Preference and Adherence to Aminosalicylates for the Treatment of Ulcerative Colitis.

Ulcerative colitis (UC) is a chronic inflammatory disorder that requires sustained treatment for optimal outcomes. The 5-aminosalicylate (5-ASA) class of medications are first-line for the treatment of mild-to-moderate UC but suffer from suboptimal adherence rates in real-world settings. This review summarizes the literature on adherence and patient preference to 5-ASA in patients with UC.

Rainfall triggers more deep-seated landslides than Cascadia earthquakes in the Oregon Coast Range, USA.

The coastal Pacific Northwest USA hosts thousands of deep-seated landslides. Historic landslides have primarily been triggered by rainfall, but the region is also prone to large earthquakes on the 1100-km-long Cascadia Subduction Zone megathrust. Little is known about the number of landslides triggered by these earthquakes because the last magnitude 9 rupture occurred in 1700 CE.

Liability issues for data monitoring committee members.

In randomized clinical trials, a data monitoring committee (DMC) is often appointed to review interim data to determine whether there is early convincing evidence of intervention benefit, lack of benefit or harm to study participants. Because DMCs bear serious responsibility for participant safety, their members may be legally liable for their actions. Despite more than three decades of experiences with DMCs, the issues of liability and indemnification have yet to receive appropriate attention from either government or industry sponsors.

Increased prevalence of lactose malabsorption in Crohn's disease patients at low risk for lactose malabsorption based on ethnic origin.

Objectives: The aim of this study was to compare the prevalence of lactose malabsorption (LM) in various subgroups of inflammatory bowel disease patients with controls matched for age, sex, and ethnic origin.

Methods: In 260 patients with IBD [121 Crohn's disease (CD) and 139 ulcerative colitis (UC)] and 158 controls at low and moderate risk for LM the prevalence of lactose malabsorption was determined by H2 breath testing.

Results: A control group at low ethnic risk had a prevalence of LM of 29.

Dietary fads and gut mysteries versus nutrition with a grain of common sense.

Although nutritional self-help literature is directed at the general public, which usually allows the authors to evade critical review by the medical and scientific community, both doctors and lay people need to read with discernment and educated scepticism when major health claims are made. Many published claims are based in misconceptions and questionable logic, and it is important to be aware of the inconsistencies and wrong conclusions commonly found in dietary fads. Patients' questions and dietary practices over the past few years have helped the present authors become familiar with certain food fads and nutrition 'self-help' books, and develop responses to popular gut topics such as food allergies, food combinations and commercial food supplements.
