Measuring patients' satisfaction with their anti-TNF treatment in severe Crohn's disease: scoring and psychometric validation of the Satisfaction for PAtients in Crohn's diseasE Questionnaire (SPACE-Q(©)).

Background: Severe Crohn's disease management includes anti-tumor necrosis factor (anti-TNF) drugs that differ from early-stage treatments regarding efficacy, safety, and convenience. This study aimed to finalize and psychometrically validate the Satisfaction for PAtients in Crohn's diseasE Questionnaire (SPACE-Q(©)), developed to measure satisfaction with anti-TNF treatment in patients with severe Crohn's disease.

Methods: A total of 279 patients with severe Crohn's disease receiving anti-TNF therapy completed the SPACE-Q 62-item pilot version at inclusion and 12 and 13 weeks after first anti-TNF injection.

A model with original conditions and materials to test potential inhibitors of cyclooxygenase-2 versus cyclooxygenase-1 in isolated human blood cells.

The inflammatory process can be influenced by an enzyme known as cyclooxygenase, which exists in two isoforms: COX-1, the constitutive form, and COX-2, which is only synthesized in the case of inflammation and has negative side effects. To decrease these undesirable effects, current research seeks to discover compounds that selectively inhibit COX-2 versus COX-1. When added to the samples, arachidonic acid activates the synthesis of COX-2.

Efficacy of low doses of radioiodine in the treatment of autonomous thyroid nodules: importance of dose/area ratio.

Radioiodine (131I) represents an interesting alternative to surgery in the treatment of autonomously functioning thyroid nodules (AFTN), but leads to a significant incidence of hypothyroidism when high doses are used. Over 4 years, we have treated 40 patients (hyperthyroid [Plummer's disease]: 6, single hot nodules with undetectable thyrotropin [TSH] and normal serum free thyroxine [FT4]: 34), 34 single hot nodules with undetectable thyrotropin TSH and normal serum free thyroxine [FT4] with 131I. The dose level was neither related to the concentration of FT4 nor to the iodine uptake on thyroid scintigram.
