Cross-National Study on the Convergent, Discriminant, and Concurrent Validity of the "Body Size Perception" Item in the Health Behaviour in School-aged Children Survey.

Background: Despite its significant usefulness in adolescent health studies, the single-item "body size perception" question, developed within the Health Behaviour in School-aged Children (HBSC) survey, has yet to undergo multidimensional validation.

Objectives: To assess the convergent, divergent and concurrent validity of the HBSC body size perception question among adolescents.

Methods: The single-item HBSC body size perception question is as follows: "Do you think your body is…?," with answers ranging from "much too thin" to "much too fat.

Profiling the patient with autoimmune hepatitis on calcineurin inhibitors: a real-world-experience.

Objective: Therapy for autoimmune hepatitis (AIH) consists of steroid induction therapy, followed by maintenance therapy with azathioprine. However, up to 20% of patients experience either insufficient response or intolerance on first-line therapy. Calcineurin inhibitors (CNIs) are frequently used when first-line therapy fails.

Inducible expression of FGF2 by a rat oligodendrocyte precursor cell line promotes CNS myelination in vitro.

Transplantation of glial cells into the central nervous system (CNS) may be a promising approach for the treatment of myelin disorders such as multiple sclerosis (MS). Myelination by transplantation of oligodendrocyte precursors has been obtained in different animal models of demyelination. A strategy to favor CNS remyelination is to enrich the lesioned areas in growth factors to stimulate the quiescent population of oligodendrocyte precursors.
