Background: Trends in abstaining from substance use and delinquency among adolescent's ages 12-17 in the United States was examined.
Methods: Data was derived from the National Survey on Drug Use and Health (NSDUH) involving non-Hispanic white, African American, and Hispanic respondents (n = 98,620) and spanning the years 2002-2014. Logistic regression was used to examine significance of trend year and correlates of low-risk and high-risk behavioral groups relative to abstaining.
Results: Overall, the prevalence of abstaining was 47.56% between 2002 and 2014. Prevalence increased significantly among all adolescents from 44.85% in 2002 to 53.58% in 2014. Relative to abstainers nonabstaining youth were more likely to be male, and report lower household income, poorer grades, depression, and lower levels of parental affirmation and control.
Conclusions: Findings indicate that there is a corresponding increase in abstaining mirroring the recent decreases found in adolescent drug use found in national surveys.

This paper describes a series of 12 9,10-dimethoxyanthracene derivatives functionalized with a range of electronically diverse ethynyl substituents at the 2 and 6 positions, aimed at tuning their optoelectronic properties and reactivity with singlet oxygen (O). Optical spectroscopy, cyclic voltammetry, and density functional theory calculations reveal that the ethynyl groups decrease the HOMO-LUMO gaps in these acenes. Notably, bis(dimethylanilineethynyl) substituents increase the wavelength of absorbance onset by over 60 nm compared to 9,10-dimethoxyanthracene (DMA).

Objective: We investigated associations between per- and polyfluoroalkyl substances (PFAS) and changes in diabetes indicators from pregnancy to 12 years after delivery among women with a history of gestational diabetes mellitus (GDM).
Research Design And Methods: Eighty Hispanic women with GDM history were followed from the third trimester of pregnancy to 12 years after delivery. Oral and intravenous glucose tolerance tests were conducted during follow-up.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

Background: The carbon-13 spirulina gastric emptying breath test (GEBT) is approved to identify delayed, but not accelerated, gastric emptying (GE). We compared the utility of the GEBT to scintigraphy for diagnosing abnormal GE in patients with diabetes mellitus.
Methods: Twenty-eight patients with diabetes ate a 230-kcal test meal labeled with technetium 99 m and C-spirulina, after which 10 scintigraphic images and breath samples (baseline, 15, 30, 45, 60, 90, 120, 150, 180, 210, and 240 min) were collected on 2 occasions 1 week apart.
Introduction: Lotilaner ophthalmic solution (0.25%) is the first United States Food and Drug Administration (US FDA)-approved drug for treating Demodex blepharitis. In pivotal trials, it was found to be well tolerated and demonstrated a significant reduction in collarettes and mite density after a 6-week treatment regimen.
