Magnetic Resonance Imaging Features Indicative of Permanent Colon Damage in Ulcerative Colitis: An Exploratory Study.

Background And Aims: It is uncertain whether ulcerative colitis leads to accumulated bowel damage on cross-sectional image. We aimed to characterise bowel damage in patients with ulcerative colitis using magnetic resonance imaging [MRI], and to determine its relation with duration of disease and the impact on patients' quality of life.

Methods: In this prospective study, patients with ulcerative colitis [UC] in endoscopic remission underwent MRI without bowel cleansing, and completed quality-of-life questionnaires.

Photodynamic nasal SARS-CoV-2 decolonization shortens infectivity and influences specific T-Cell responses.

Background: The main objective was to evaluate the efficacy of intranasal photodynamic therapy (PDT) in SARS-CoV-2 mildly symptomatic carriers on decreasing the infectivity period. SARS-CoV-2-specific immune-stimulating effects and safety were also analysed.

Methods: We performed a randomized, placebo-controlled, clinical trial in a tertiary hospital (NCT05184205).

Volar Capsulodesis With Early Active Motion for the Treatment of Chronic Proximal Interphalangeal Joint Hyperextension Deformity.

Purpose: We evaluated the clinical outcomes of a series of patients with hyperextension deformity of the proximal interphalangeal joint treated with volar capsulodesis.

Methods: This retrospective study included 16 patients with symptomatic locking of the proximal interphalangeal joint who underwent volar capsulodesis and were followed for at least 2 years. We excluded patients with severe, degenerative changes on plain radiographs.

Status of gastrointestinal nematode infections and associated epidemiological factors in sheep from Córdoba, Colombia.

Gastrointestinal nematodes cause serious economic losses in sheep production systems. To determine the prevalence and risk factors associated with these parasites, a study was conducted on 595 sheep in Córdoba, Colombia. Prevalence and parasite burden were determined using the McMaster technique.
