HIV Immunocapture Reveals Particles Expressed in Semen Under Integrase Strand Transfer Inhibitor-Based Therapy Are Largely Myeloid Cell-Derived and Disparate.

As use of human immunodeficiency virus (HIV) integrase strand transfer inhibitors (INSTI) increases and formulations are being developed for maintenance therapies and chemoprophylaxis, assessing virus suppression under INSTI-based regimens in prevention-relevant biologic compartments, such as the male genital tract, is timely. We used cell-source marker virion immunocapture to examine amplification of particle RNA then assessed the phylogenetic relatedness of seminal and blood viral sequences from men with HIV who were prescribed INSTI-based regimens. Seminal plasma immunocaptures yielded amplifiable virion RNA from 13 of 24 (54%) men, and the sequences were primarily associated with markers indicative of macrophage and resident dendritic cell sources.

Pregnancy Outcomes in Women with Poorly Controlled Pregestational Diabetes Mellitus.

Background: The prevalence of pregestational diabetes mellitus (PGDM) in women of reproductive age has surged globally, contributing to increased rates of adverse pregnancy outcomes. Hemoglobin A1c (HbA1c) is a crucial marker for diagnosing and monitoring PGDM, with periconceptional levels influencing the risk of congenital anomalies and complications.

Objectives: To evaluate the association between periconceptional HbA1c levels and perinatal complications in pregnant women with poorly controlled PGDM.

Safety and Tolerability of Once Daily Coformulated Bictegravir, Emtricitabine, and Tenofovir Alafenamide for Postexposure Prophylaxis After Sexual Exposure.

Background: Antiretroviral post-exposure prophylaxis (PEP) is recommended to prevent HIV infection after a high-risk exposure, but current regimens have presented challenges in tolerability, regimen completion, and potential drug-drug interactions. Because coformulated bictegravir, emtricitabine, and tenofovir alafenamide [BIC/FTC/tenofovir alafenamide (TAF)] is effective for HIV treatment, it was evaluated for use for PEP.

Setting: Boston community health center.

COVID-19 in spinal cord injury patients at a veterans administration hospital: A case series.

Objective: To describe the clinical features and disease course of COVID-19 in veterans with spinal cord injury (SCI).

Design: Case series of consecutive veterans with SCI treated at a single center.

Setting: SCI Unit at an urban Veterans Administration hospital at the epicenter of the COVID-19 pandemic in the US.

Abdominal circumference discordance for prediction of small for gestational age at birth in twin pregnancies.

Objective: To evaluate whether single sonographic abdominal circumference (AC) discordancy estimation can predict small for gestational age (SGA) at birth in twin gestations.

Methods: A retrospective analysis of prospectively collected data. Cohort included all twin gestations delivered at one university-affiliated medical center between 2010 and 2018, with available sonographic evaluation from 22 gestational weeks to term.
