Tenofovir-Diphosphate and Emtricitabine-Triphosphate Adherence Benchmarks in Dried Blood Spots for Persons With HIV Receiving Tenofovir Alafenamide and Emtricitabine-Based Antiretroviral Therapy (QUANTI-TAF).

Background: QUANTI-TAF aimed to establish tenofovir-diphosphate (TFV-DP)/emtricitabine-triphosphate (FTC-TP) adherence benchmarks in dried blood spots (DBS) for persons with human immunodeficiency virus (PWH) receiving tenofovir alafenamide/emtricitabine (TAF/FTC)-based antiretroviral therapy (ART).

Methods: For 16 weeks, PWH received TAF/FTC-based ART co-encapsulated with an ingestible sensor to directly measure cumulative (enrollment to final visit) and 10-day adherence. At monthly visits, intraerythrocytic concentrations of TFV-DP and FTC-TP in DBS were quantified and summarized at steady-state (week 12 or 16) as median (interquartile range).

A Novel Digital Pill System for Medication Adherence Measurement and Reporting: Usability Validation Study.

Background: Medication nonadherence is a costly problem that is common in clinical use and clinical trials alike, with significant adverse consequences. Digital pill systems have proved to be effective and safe solutions to the challenges of nonadherence, with documented success in improving adherence and health outcomes.

Objective: The aim of this human factors validation study is to evaluate a novel digital pill system, the ID-Cap System from etectRx, for usability among patient users in a simulated real-world use environment.

Performance, Reliability, Usability, and Safety of the ID-Cap System for Ingestion Event Monitoring in Healthy Volunteers: A Pilot Study.

Nonadherence to prescribed medications is an important consideration in the clinical management of patients and in clinical research and drug development. The ID-Cap System is a novel technology that provides an objective measure of medication ingestion and enables real-time reporting of verified medication adherence data at the dose level. The ID-Cap System consists of an ingestible microsensor that is embedded in an oral dosage form and, once activated by stomach fluid, communicates digital messages to an external wearable reader to confirm ingestion.

Hypothalamic pituitary adrenal function in the extremely low birth weight infant.

Extremely premature infants manifest clinical features suggestive of adrenal insufficiency. Yet, serum cortisol levels are similar in ill and well preterm infants in a setting where one would expect high stress levels in the ill infants. We investigated the hypothalamic-pituitary-adrenal axis in 17 extremely low birth weight stressed premature infants, mean birth weight 739 g, gestational age, 26.

Ductal patency in neonates with respiratory distress syndrome. A randomized surfactant trial.

The purpose of this study was to evaluate in a controlled study the effect of exogenous surfactant on various manifestations of ductal patency. Premature infants with respiratory distress syndrome were randomized to receive surfactant (Survanta) (n = 22) or air (n = 14). In neonates receiving surfactant, there was a greater tendency for an audible murmur to develop (13 of 22 vs four of 14).
