PET-CT Defined Micro-Vascular Dysfunction and Cardiac Allograft Vasculopathy Risk Factors in Heart Transplant Recipients.

Microvascular dysfunction (MVD) is considered a form of cardiac allograft vasculopathy (CAV), independently associated with poor prognosis after heart transplantation (HTX). It is unknown whether traditional risk factors for CAV are also applicable to MVD. We retrospectively analyzed factors associated with MVD in 94 HTX recipients who completed a PET scan after a normal baseline left heart catheterization excluding epicardial CAV.

Oral motor interventions used to support the development of oral feeding skills in preterm infants: An integrative review.

Background: One criterion for infant NICU discharge is the ability to meet all nutritional needs by mouth, therefore, it is important to understand interventions that can improve the trajectory to full oral feeding. While many oral motor and feeding interventions are used in clinical practice, it remains unclear which are supported by the literature.

Aim: The aim of this integrative review was to identify and understand what oral motor interventions are defined in the literature to support positive outcomes for preterm infants and their parents.

Hypertensive Disorders of Pregnancy: Innovative Management Strategies.

Hypertensive disorders of pregnancy (HDP) complicate 13% to 15% of pregnancies in the United States. Historically marginalized communities are at increased risk, with preeclampsia and eclampsia being the leading cause of death in this population. Pregnant individuals with HDP require more frequent and intensive monitoring throughout the antepartum period outside of routine standard of care prenatal visits.

No effect of tattoos on local sweat concentrations of select cytokines, cortisol, glucose, blood urea nitrogen, or lactate during exercise.

Due to growing interest in the investigation of exercise induced sweat biomarkers to assess an individual's health and the increasing prevalence of tattoos in the world's population, investigators sought to determine whether local sweat concentrations and excretion rates of epidermal growth factor (EGF), interleukin (IL) -1α, IL-6, IL-8, cortisol, glucose, blood urea nitrogen (BUN), and lactate differ between tattooed and contralateral non-tattooed skin during exercise. Sixteen recreational exercisers [female (50%)] (age = 25-48 years) with ≥ 1 unilateral permanent tattoo [median tattoo age = 6 years, IQR = 5] on the arm/torso completed an outdoor group fitness session. There were no significant differences between tattooed and non-tattooed skin for sweat EGF, IL-1α, IL-8, cortisol, glucose, BUN, or lactate concentrations.

Evaluating the impact of point-of-care HIV viral load assessment on linkage to care in Baltimore, MD: a randomized controlled trial.

Background: Integration of a sensitive point-of-care (POC) HIV viral load (VL) test into screening algorithms may help detect acute HIV infection earlier, identify people with HIV (PWH) who are not virally suppressed, and facilitate earlier referral to antiretroviral therapy (ART), or evaluation for pre-exposure prophylaxis (PrEP). This report describes a randomized clinical trial sponsored by the Centers for Disease Control and Prevention (CDC): "Ending the HIV Epidemic Through Point-of-Care Technologies" (EHPOC). The study's primary aim is to evaluate the use of a POC HIV VL test as part of a testing approach and assess the impact on time to linkage to ART or PrEP.
