X-linked hypophosphatemia (XLH) is a rare metabolic disorder characterized by elevated FGF23 and chronic hypophosphatemia, leading to impaired skeletal mineralization and enthesopathies that are associated with pain, stiffness, and diminished quality of life. The natural history of enthesopathies in XLH remains poorly defined, partly due to absence of a sensitive quantitative tool for assessment and monitoring. This study investigates the utility of 18F-NaF PET/CT scans in characterizing enthesopathies in XLH subjects.

Background: The practice choices of family medicine residents and early career family physicians shape access to primary care. A growing proportion of family physicians are women.

Aim: This study examined how gender operates in shaping family physician practice choices and subsequent practice patterns.

Background: Olutasidenib is a potent, selective, oral, small molecule inhibitor of mutant IDH1 (mIDH1) which induced durable remissions in high-risk, relapsed/refractory (R/R) mIDH1 AML patients in a phase 1/2 trial. We present a pooled analysis from multiple cohorts of the phase 1/2 trial of patients with R/R AML who received combination olutasidenib and azacitidine therapy.

Methods: Adult patients with mIDH1 AML received 150 mg olutasidenib twice daily plus standard-of-care azacitidine (OLU + AZA) and were evaluated for response and safety.

With optometrists well placed to address the challenges and opportunities faced by contemporary eye care systems, it is ever more important to understand the genesis and development of the profession, so that optometrists can continue to build on this legacy for patient benefit. While the optometry profession of optometry in the United Kingdom can arguably trace its foundation back to 1629 and the Royal Charter gifted by Charles I to the Worshipful Company of Spectacle Makers to establish the 60 Livery Company of the City of London, the genesis of optometry as an independent profession (initially known as 'ophthalmic optics') can perhaps best be attributed to the formation of the British Optical Association in 1895. This paper reviews the current legal framework and recent changes that dictates how the optometry profession are trained and practice, along with clinical and educational innovations that are shaping the future role of the profession.

Rationalizing the role of chemical interactions in the precursor solutions on the structure, morphology, and performance of thin-film CuZnSn(S,Se) (CZTSSe) is key for the development of bifacial and other photovoltaic (PV) device architectures designed by scalable solution-based methods. In this study, we uncover the impact of dimethylformamide (DMF) and isopropanol (IPA) solvent mixtures on cation complexation and rheology of the precursor solution, as well as the corresponding morphology, composition, and PV performance of CZTSSe thin-film grown on fluorine-doped tin oxide (FTO). We find that increasing the proportion of IPA leads to a nonlinear increase in dynamic viscosity due to the strong repulsion between DMF and IPA, which is characterized by an interaction cohesion parameter of 3.
