Nurse practitioner race and ethnicity and interest in independent primary care practice and serving Medicaid enrollees.

Nurse practitioners (NPs) are important providers of primary care to underserved populations, particularly in areas with lower physician supply. In 2023, California implemented new regulations aimed at improving access to care, especially primary care services, by providing a pathway for NPs to practice without formal supervision after 3 years of practice and without any physician relationship after 5 years of practice. This study used data from a representative survey of California-licensed NPs fielded in late 2022 to examine NPs' current practice and intentions following implementation of the new regulations.

Hemodynamic effects of bifurcation and stenosis geometry on carotid arteries with different degrees of stenosis.

Carotid artery stenosis (CAS) is a key factor in pathological conditions, such as thrombosis, which is closely linked to hemodynamic parameters. Existing research often focuses on analyzing the influence of geometric characteristics at the stenosis site, making it difficult to predict the effects of overall vascular geometry on hemodynamic parameters. The objective of this study is to comprehensively examine the influence of geometric morphology at different degrees of CAS and at bifurcation sites on hemodynamic parameters.

An Innovation Ethics Framework for Safe and Equitable Contingency Planning.

AbstractThe contingency phase is a transition period between usual healthcare delivery and the activation of formalized rationing protocols under crisis standards of care. The contingency phase is defined by two simultaneous goals: avert or forestall critical scarcity of healthcare resources, and provide patient-centered care that is functionally equivalent to usual care when dynamic changes to healthcare operations are necessary to prevent hospital surge overload. Contingency measures modify the allocation of hospital space, staff, and supplies in service of these two goals.

Testosterone Therapy for the Treatment of Unexplained Anemia in Men With Hypogonadism.

Decreased testosterone levels are often under-recognized as a cause of anemia in males with hypogonadism. Men, as a subset, are less likely to seek medical care, especially those who struggle with complex psychiatric and social conditions, where they may lack full autonomy. Increasing testosterone levels leads to erythrocytosis by elevating erythropoietin and soluble transferrin receptor levels and suppressing hepcidin and ferritin levels.
