Describing ZYN-related content on TikTok: content analysis.

Introduction: Nicotine pouches are the fastest-growing oral smokeless tobacco or nicotine product category in the United States, and there are concerns about their potential appeal to youth. Few studies have surveilled discussions about nicotine pouches on TikTok, an audiovisual platform popular among youth. To address this gap, this study conducted a content analysis of TikTok posts related to the leading nicotine pouch brand, ZYN.

Future destinations: how people cured of hepatitis C using direct acting antiviral drugs progress in a new HCV-free world. A thematic analysis.

Background: The introduction of Direct-Acting Antivirals (DAAs) transformed Hepatitis C (HCV) treatment, despite this uptake of DAAs remains lower than required to meet the WHO Sustainable Development Goal (3.3). Treatment with interferon was suggested to be able to deliver important outcomes for people who use drugs in addition to a viral cure, such as social redemption, and shift from a stigmatised identity.

Superconductivity in ordered Li-Al-B compounds.

Using first principles calculations, we show that [Formula: see text] materials have strong electron-phonon coupling, with many having a superconducting critical temperature ([Formula: see text]) that exceeds that of the more familiar [Formula: see text] at ambient pressure. In particular, we find that [Formula: see text] is the most stable member of the family, with [Formula: see text] whilst the peak [Formula: see text] is with [Formula: see text] which has [Formula: see text]. Our results reveal that these materials are both thermodynamically and dynamically stable, with strong electron-phonon coupling, indicating significant potential for practical superconducting applications.

Glycemia and Insulin Secretion in Cystic Fibrosis Two Years After Elexacaftor/Tezacaftor/Ivacaftor: PROMISE-ENDO.

Background: Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective therapy that improves lung disease in people with cystic fibrosis (pwCF), but its effect on glucose tolerance and insulin secretion is unclear.

Methods: PROMISE is a multicenter prospective, observational study of ETI in pwCF ≥12 years and at least one F508del allele. The PROMISE Endocrine sub-study (PROMISE-ENDO) enrolled participants at 10 CF Centers where hemoglobin A1c (HbA1c) was collected and 3-hour oral glucose tolerance tests (OGTT) conducted to examine glucose tolerance, glucose excursions, insulin secretory rates (deconvolution of C-peptide) and sensitivity (oral minimal model) prior to ETI and 12-18 months (mos) and 24-30 mos following ETI initiation.
