Potential gains in PrEP coverage and effect on racial disparities following introduction of on-demand and long-acting injectable PrEP: Preferences of men who have sex with men in the United States, 2021-2022.

Introduction: There are persistent race- and ethnicity-based disparities in HIV incidence among gay and bisexual men who have sex with men (GBMSM) in the United States, partially driven by inequities in distribution of pre-exposure prophylaxis (PrEP). We assessed how additional modalities of PrEP beyond daily oral might affect uptake of PrEP and ongoing disparities in HIV incidence in the US.

Methods: In an online survey of GBMSM in the US, we presented participants with descriptions of each PrEP modality.

Does Amsterdam criteria applied to largely unsubmitted term placentas with favorable fetal outcomes show significant maternal clinicopathologic correlation?

Objectives: Before the Amsterdam Placental Workshop Group Consensus Statement, standardization in placental pathology assessment did not exist. This study evaluated the Amsterdam criteria's utility in correlating ischemic placental disease (IPD) with placental pathologic lesions in a cohort of largely unsubmitted term placentas with favorable outcomes.

Methods: In this prospective case-controlled study at a single institution, all placentas were examined using Amsterdam protocols for gross sampling and microscopic review by 2 reviewers who were blinded to clinical history.

A retrospective cohort analysis of alignment parameters for spinal tumor patients with instrumentation at the cervicothoracic junction.

Background: Previous research on spinal alignment and postoperative outcomes after cervical and upper thoracic fixation has suggested that clinical and patient-reported outcomes are improved when certain anatomical parameters are maintained. These parameters include the cervical sagittal vertical axis (cSVA), C2 and T1 slopes, and cervical lordosis (CL). For patients with primary and metastatic tumors involving the subaxial cervical and/or upper thoracic spine, there is minimal guidance on how to apply these parameters.

Connecting genomic results for psychiatric disorders to human brain cell types and regions reveals convergence with functional connectivity.

Identifying cell types and brain regions critical for psychiatric disorders and brain traits is essential for targeted neurobiological research. By integrating genomic insights from genome-wide association studies with a comprehensive single-cell transcriptomic atlas of the adult human brain, we prioritized specific neuronal clusters significantly enriched for the SNP-heritabilities for schizophrenia, bipolar disorder, and major depressive disorder along with intelligence, education, and neuroticism. Extrapolation of cell-type results to brain regions reveals the whole-brain impact of schizophrenia genetic risk, with subregions in the hippocampus and amygdala exhibiting the most significant enrichment of SNP-heritability.
