An Improved GC-MS/MS Method for a Fast Multidrug Analysis in Hair.

This study presents the development and validation of a drug testing method in hair, employing a semi-automated sample preparation procedure and gas chromatography-tandem mass spectrometry (GC-MS/MS) for simultaneous multidrug analysis in hair. The method aims to detect and quantify multiple drugs in hair, including amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, ketamine, norketamine, cocaine, benzoylecgonine, morphine, codeine and 6-monoacetylmorphine, using a comprehensive procedure involving decontamination, pulverization, clean-up using supported-liquid extraction (SLE) and a two-step derivatization process. The method validation included specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, carryover, robustness and stability.

Long-term quality of life and surgical outcome of female congenital adrenal hyperplasia patients.

Aim: To investigate the long-term quality of life and surgical outcome of female patients with congenital adrenal hyperplasia (CAH).

Methods: Questionnaires for health-related quality of life (HRQoL) outcome (WHO-5, SF-36), lower urinary tract symptoms (ICIQ-FLUTS) and sexual outcome (ICIQ-FLUTSsex) were administered to adult CAH patients. Paediatric CAH patients and their parents were invited to complete WHO-5, PedsQL-4.

Enhancing Resonant Second-Harmonic Generation in Bilayer WSe by Layer-Dependent Exciton-Polaron Effect.

Two-dimensional (2D) materials serve as exceptional platforms for controlled second-harmonic generation (SHG). Current approaches to SHG control often depend on nonresonant conditions or symmetry breaking via single-gate control. Here, we employ dual-gate bilayer WSe to demonstrate an SHG enhancement concept that leverages strong exciton resonance and a layer-dependent exciton-polaron effect.

Is Childhood Adversity Before Age 5 Associated with Adolescent and Young Adult Substance Use? Findings from a U.S. Prospective Cohort Study.

Objective: Growing research suggests that adversity experienced early in life can affect young children's development, with implications for health-related outcomes years later. This study explored long-term associations between early life adversity before age 5 (ELA) and later substance use outcomes, and racial and ethnic differences in associations.

Method: Data are from children born 1984-2000 to female participants in the U.
