Racial, Socioeconomic, and Geographic Disparities in Preamputation Vascular Care for Patients With Chronic Limb-Threatening Ischemia.

Background: Black patients, those with low socioeconomic status (SES), and those living in rural areas have elevated rates of major lower extremity amputation, which may be related to a lack of subspecialty chronic limb-threatening ischemia care. We evaluated the association between race, rurality, SES, and preamputation vascular care.

Methods: Among patients aged 66 to 86 years with fee-for-service Medicare who underwent major lower extremity amputation for chronic limb-threatening ischemia from July 2010 to December 2019, we compared the proportion who received vascular care in the 12 months before amputation by race (Black versus White), rurality, and SES (dual eligibility for Medicaid versus no dual eligibility) using multivariable logistic regression adjusting for clinical and demographic covariates.

Deep transcranial magnetic stimulation for adolescents with treatment-resistant depression: Behavioral and neural correlates of clinical improvement.

Background: Affective bias toward negativity is associated with depression and may represent a promising treatment target. Stimulating the dorsolateral prefrontal cortex (dlPFC) with deep Transcranial Magnetic Stimulation (dTMS) could lead to shifts in affective bias. The current study examined behavioral and neural correlates of affective bias in the context of dTMS in adolescents with treatment-resistant depression (TRD).

Different Grey Matter Microstructural Patterns in Cognitively Healthy Versus Typical Ageing Healthy Versus Typical Brain Ageing.

Ageing is a complex phenomenon affecting a wide range of coexisting biological processes. The homogeneity of the studied population is an essential parameter for valid interpretations of outcomes. The presented study capitalises on the MRI data available in the Human Connectome Project-Aging (HCP-A) and, within individuals over 55 years of age who passed the HCP-A section criteria, compares a subgroup of 37 apparently neurocognitively healthy individuals selected based on stringent criteria with 37 age and sex-matched individuals still representative of typical ageing but who did not pass the stringent definition of neurocognitively healthy.

Contribution margins and utilization of transcatheter aortic valve replacement versus surgical aortic valve replacement in the Medicare population.

Background: Hospitals and health systems must balance the demand for transcatheter aortic valve replacement (TAVR) against financial sustainability. Patients may be eligible for both TAVR and surgical aortic valve replacement (SAVR), but financial realities for hospitals may affect differential access to those therapies. We sought to understand the landscape of costs and reimbursement for TAVR and SAVR in the US and to understand the association of procedural reimbursement with receipt of either.
