Pilot and feasibility study of dietary composition with elexacaftor-tezacaftor-ivacaftor concentrations in people with cystic fibrosis.

Background: Nutritional support for people with cystic fibrosis (PwCF) after the implementation of novel drug therapies is shifting from managing malnutrition through a high-fat, high-calorie diet to managing emerging incidences of obesity in this population. Additionally, dietary recommendations prescribed with elexacaftor/tezacaftor/ivacaftor (ETI) recommend taking this drug with a fat-containing meal, which is variably interpreted by patients. This pilot and feasibility study was conducted to assess dietary fat intake and body composition on ETI plasma concentrations.

Risks of grade reclassification among patients with Gleason grade group 1 prostate cancer and PI-RADS 5 findings on prostate MRI.

Background And Objective: As most Prostate Imaging Reporting and Data System (PI-RADS) 5 lesions on MRI harbor Gleason grade (GG) group ≥2 disease on biopsy, optimal management of patients with imaging-biopsy discordance remains unclear. To estimate grade misclassification, we evaluated the incidence of Gleason upgrading among patients with GG1 disease in the setting of a PI-RADS 5 lesion.

Methods: We conducted a single-institution retrospective analysis to identify patients with GG1 prostate cancer on fusion biopsy with MRI demonstrating ≥1 PI-RADS 5 lesion.

Management of Keloids and Hypertrophic Scars.

Keloid and hypertrophic scars are a result of aberrant wound healing responses within the reticular dermis. They are thought to be secondary to the formation of a disorganized extracellular matrix due to excessive fibroproliferative collagen response. Prevention of these scars focuses on avoiding elective or cosmetic procedures such as piercings in patients at high risk, reducing tension across the lesion, and decreasing the inflammatory response.

Palladium Bisphosphine Monoxide Complexes: Synthesis, Scope, Mechanism, and Catalytic Relevance.

Recent studies in transition metal catalysis employing chelating phosphines have suggested a role for partial ligand oxidation in formation of the catalytically active species, with potentially widespread relevance in a number of catalytic systems. We examine the internal redox reaction of Pd(bisphosphine)X (X = Cl, OAc, ) complexes to reveal previously underexplored aspects of bisphosphine monoxides (BPMOs), including evaluation of ligand structure and development of general reaction conditions to access a collection of structurally diverse BPMO precatalysts based on organopalladium oxidative addition complexes. In particular, a series of Pd(BPMO)(R)(X) (R = aryl, alkyl; X = I, Br) oxidative addition complexes bearing 24 different BPMO ligands were characterized by NMR and X-ray crystallography.
