Phase 1 Studies to Assess Inhaled Seralutinib as a Perpetrator or a Victim of Drug-Drug Interactions in Healthy Participants.

Seralutinib, an inhaled, small-molecule tyrosine kinase inhibitor in clinical development for the treatment of pulmonary arterial hypertension (PAH), was evaluated for its potential as a perpetrator or victim of a metabolic and transporter-based drug-drug interactions in 2 phase 1 studies. In study 1, 24 participants received a cocktail of probe substrates: caffeine (CYP1A2), montelukast (CYP2C8), flurbiprofen (CYP2C9), midazolam (CYP3A), and pravastatin (OATP1B1/1B3), plus digoxin (P-gp) with or without seralutinib. In study 2, 19 participants received seralutinib with/without itraconazole, a strong CYP3A inhibitor, or fosaprepitant, a weak CYP3A inhibitor.

Translation, cross-cultural adaptation, and measurement properties of the prolapse and incontinence knowledge quiz (PIKQ-Br) for Brazilian women with urinary incontinence.

Background: The Prolapse and Incontinence Knowledge Quiz (PIKQ) was developed to assess women's knowledge of pelvic organ prolapse (POP) and urinary incontinence (UI).

Objective: To perform the translation, cross-cultural adaptation, and measurement properties of the PIKQ for Brazilian women with UI (PIKQ-Br).

Methods: The measurement properties were tested for validity (content and face, structural, and hypotheses testing) and reliability (internal consistency, test-retest, and measurement error) in 130 women with UI from Recife, Brazil.

Serum Glial Fibrillary Acidic Protein and Neurofilament Light Chain Levels Reflect Different Mechanisms of Disease Progression under B-Cell Depleting Treatment in Multiple Sclerosis.

Objective: To investigate the longitudinal dynamics of serum glial fibrillary acidic protein (sGFAP) and serum neurofilament light chain (sNfL) levels in people with multiple sclerosis (pwMS) under B-cell depleting therapy (BCDT) and their capacity to prognosticate future progression independent of relapse activity (PIRA) events.

Methods: A total of 362 pwMS (1,480 samples) starting BCDT in the Swiss Multiple Sclerosis (MS) Cohort were included. sGFAP levels in 2,861 control persons (4,943 samples) provided normative data to calculate adjusted Z scores.

Probing and gauging of D-Penicillamine xenobiotics in hepatic Wilson disease patients.

D-penicillamine (PA) is the primary chelator of choice to treat Wilson disease (WD). There are limitations in obtaining comprehensive data on PA metabolites in biological specimens by conventional approaches. Hence, the aim of the present was to identify the major hepatic PA metabolites and draw clear conclusions of the drug's xenobiotic in WD.
