Long-term treatment outcomes of mindfulness-based cognitive therapy for fatigue in patients with inflammatory bowel disease: Results of a randomized controlled trial.

Objectives: Fatigue is prevalent in patients with inflammatory bowel disease (IBD) in remission. Previously, we showed that fatigued IBD patients experienced a significant decrease in fatigue after receiving mindfulness-based cognitive therapy (MBCT). The current study examined to what extent these short-term beneficial effects of MBCT on fatigue were maintained over nine months follow-up, and whether patient characteristics were associated with clinically relevant improvement in fatigue.

Microscopic colitis: an unfamiliar but treatable disease.

Chronic diarrhoea is a frequent complaint in clinical practice. Microscopic colitis is the cause of this symptom in 10% of these cases and the prevalence is rising. To exclude microscopic colitis a colonoscopy with multiple biopsies of different regions of the colon is mandatory.

Directional flow induced by synchronized longitudinal and zeta-potential controlling AC-electrical fields.

Electroosmotic flow (EOF) in a microchannel can be controlled by electronic control of the surface charge using an electrode embedded in the wall of the channel. By setting a voltage to the electrode, the zeta-potential at the wall can be changed locally. Thus, the electrode acts as a "gate" for liquid flow, in analogy with a gate in a field-effect transistor.
