Impact of Once-Weekly Rifapentine and Isoniazid on the Steady State Pharmacokinetics of Dolutegravir and Darunavir Boosted With Cobicistat in Healthy Volunteers

Rifapentine (RPT) is a long-acting rifamycin that can be used weekly with isoniazid (INH) as a first-line regimen in the treatment of latent tuberculosis infection (LTBI). Although this regimen offers several potential benefits, the use of weekly RPT plus INH is not currently recommended in adults infected with human immunodeficiency …

Mental Health Impact of COVID-19 Pandemic on NIMH Research Participants and Volunteers

Study Description: This protocol leverages existing NIMH studies and participants to accomplish time-sensitive research on the mental health impact of environmental stressors imposed by the COVID-19 pandemic. The study will describe the relationship between stressors related to COVID-19 and self-rated measures of mental health symptoms and distress among a range …

Technical Development of Clinical Laboratory Studies

Objective The purpose of this protocol is to get adequate normal values to compare in clinical patient studies. Study population There will be two techniques developed in this study: Somatosensory Temporal Discrimination Threshold (STDT) and Acoustic Startle Reflex (ASR). For both studies we will collect data systematically in an adequate …

Causes and Natural History of Dyslipidemias

The lipoprotein transport system is vital to the delivery of the hydrophobic fats that are carried in the aqueous environment of the blood. The lipoprotein particles that comprise this system are polydisperse and contain triglycerides, free and esterified cholesterol, phospholipids and proteins. Inborn errors in the lipoprotein transport system lead …

Study of New Magnetic Resonance Imaging Methods of the Brain

Objective The goal of this protocol is to improve spatial resolution and contrast in MRI studies of brain anatomy and function, by developing novel hardware, and image acquisition and reconstruction techniques. Specifically, by improving MRI image quality and manipulating MRI contrast, we aim to better characterize and quantify structural, chemical, …

Systems Analyses of the Immune Response to the Seasonal Influenza Vaccine

Certain functions of the immune system are revealed only when the immune system is challenged. When a person is vaccinated, a coordinated response results: activation and interaction of distinct innate and adaptive immune cell populations and pathways, culminating in the formation of germinal centers from which antibody-producing plasma cells and …

Changes in PPV Induced by PLR Test to Predict Fluid Responsiveness in ICU

The passive leg raising (PLR) test is a reversible preload challenge of around 300 mL of blood that can be repeated as frequently as required without infusing a drop of fluid. Two recent meta-analyses of many studies have confirmed the reliability of the PLR test to predict fluid responsiveness in …
