This study aimed to examine the relationship between externalizing behaviors, substance use, and sexual risk among adolescent girls and young women (AGYW) in Cape Town, South Africa, who experience social disadvantage characterized by poverty and school dropout. We analyzed baseline data from 500 AGYW in a cluster-randomized trial who had dropped out of school. Multivariate logistic regression models explored associations between self-reported criminal behaviors and other status offenses, heavy episodic drinking, polydrug use, and condomless sex.

Our objective is to investigate whether AI systems utilising standardised objective metrics (SOMs) as the basis of skill assessment can provide a clearer understanding of the current state of such technology.
Methods: We systematically searched Medline, Embase, Scopus, CENTRAL and Web of Science from March 2023 to September 2023.
Introduction: This Rapid Review (RR) aimed to assess the current literature over the past decade to determine the prevailing evidence regarding compulsory treatment* in eating disorders (ED). It is hoped that the review will help inform a consensus opinion as to whether this course of action confers significant clinical benefit, and importantly, to whom it should apply. The review also explores alternative options to involuntary care.

We found that plays a role in germline stem cell progeny differentiation. and its neighbor, the lncRNA , originate and are co-expressed from a singular polycistronic non-coding RNA locus.

Bone fragility is a well-documented long-term side effect of radiotherapy, which currently has no preventative treatments. In this study, we applied a caloric restriction (CR) diet to attenuate both local and systemic bone loss after irradiation (RTx) in an established female Balb/c mouse model (4 consecutive daily doses of 5 Gy to the right hindlimb only). CR mice were tapered down to a 30% reduced calorie diet (RTx/CR) one week before irradiation, while regular diet (RD) mice received food ad libitum (RTx/RD).

Methods: Focus group discussions (FGDs) were conducted with 34 participants who had previous or current drug-susceptible TB and self-reported current alcohol use.
The prevalence and influence of gangs on adolescents and young adults remain a concern in Western Cape, South Africa-particularly as they have one of the largest gang presence. While less attention has been focused on young women, there is a need to elucidate the relationship between gang exposure and health behaviors, such substance use, in addition to understanding whether becoming a caregiver impacts this relationship. This study uses baseline data from 496 participants enrolled in a NIDA-funded R01 trial that recruited young women aged 16 to 19 who were out of school and reported recent alcohol or other drug use and sexual risk behavior.

Objectives: To investigate the impact of alcohol and illicit substance use on the pharmacokinetics of first-line TB drugs in participants with pulmonary TB.
The plane-wave pseudopotential (PW-PP) formalism is widely used for the first-principles electronic structure calculation of extended periodic systems. The PW-PP approach has also been adapted for real-time time-dependent density functional theory (RT-TDDFT) to investigate time-dependent electronic dynamical phenomena. In this work, we detail recent advances in the PW-PP formalism for RT-TDDFT, particularly how maximally localized Wannier functions (MLWFs) are used to accelerate simulations using the exact exchange.

Aim 1, conducted during the formative phase, was to modify the original Couples Health CoOp (CHC) intervention to include antiretroviral therapy/pre-exposure prophylaxis (ART/PrEP), called the Couples Health CoOp Plus (CHC+), with review from our Community Collaborative Board and a Peer Advisory Board.

It can manifest spontaneously in rare genetic conditions or as a response to injury, known as acquired heterotopic ossification. There are several experimental models for studying acquired heterotopic ossification from different sources of damage.

A cluster randomised trial in Cape Town allocated 24 Black and Coloured communities to a gender-focused HIV risk-reduction intervention or HIV testing, with 500 AGYW total enrolled. We evaluated intervention efficacy by comparing mean differences overall, by community population group (Black and Coloured) and among those with structural barriers based on neighbourhood, education, and employment (n = 406).

The formation of cristae requires the presence of a protein complex known as MICOS, which is conserved across eukaryotic species. One of the subunits of this complex, MIC10, is a transmembrane protein that supports cristae formation by oligomerization.
View Article and Find Full Text PDFBackground: Condom use among young people in South Africa has declined in recent years and adolescent girls and young women continue to bear the highest incidence of HIV in the country. Young women who have dropped out of school may be more at risk because of traditional gender norms that create substantial power imbalances and a lack of power to negotiate condom use with their male partners, especially when using alcohol and other drugs.
Methods: This study presents an analysis of baseline data provided by 500 adolescent girls and young women (AGYW) from Cape Town communities between November 2016 and November 2018 who were reached for a cluster-randomised trial conducted to assess the efficacy of an evidence-based, young woman-focused intervention seeking to reduce HIV risk and substance use behaviours.
ADHD is a neurocognitive disorder characterized by attention difficulties, hyperactivity, and impulsivity, often persisting into adulthood with substantial personal and societal consequences. Despite the importance of neurophysiological assessment and treatment monitoring tests, their availability outside of research settings remains limited. Cognitive neuroscience investigations have identified distinct components associated with ADHD, including deficits in sustained attention, inefficient enhancement of attended Targets, and altered suppression of ignored Distractors.

Background: Unhealthy alcohol use is widespread in South Africa and has been linked to tuberculosis (TB) disease and poor treatment outcomes. This study used qualitative methods to explore the relationship between TB and alcohol use during TB treatment.

Little is known about sexual and gender minority youth (SGMY) who have sex with men's unique patterns of substance use, even though they are at risk for substance use and adverse mental and other health outcomes. We used latent class analysis to examine typologies of substance use and multinomial logistic regression to investigate mental health outcomes (depression and anxiety) and HIV/STI testing correlates associated with different classes of substance use in a sample of SGMY who have sex with men in the USA and use substances (n = 414) who participated in an online survey. The average age was 22.

It is the wrong question because guardianship does not exist in isolation from other institutions and legal instruments, such as enduring powers and nominee powers, or informal community arrangements of support or substituted decision-making. It is the wrong question because archetypical purity of guardianship as substitution and support as autonomy does not reflect real world experience of it as it is always a mixture of both, changing over time and decision type; and because change is very hard to pin down.
