Introduction: Despite viral suppression due to combination antiretroviral therapy (cART), HIV-associated neurocognitive disorders (HAND) continue to affect half of people with HIV, suggesting that certain antiretrovirals (ARVs) may contribute to HAND.

Methods: We examined the effects of nucleoside/nucleotide reverse transcriptase inhibitors tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) and the integrase inhibitors dolutegravir (DTG) and elvitegravir (EVG) on viability, structure, and function of glutamatergic neurons (a subtype of CNS neuron involved in cognition) derived from human induced pluripotent stem cells (hiPSC-neurons), and primary human neural precursor cells (hNPCs), which are responsible for neurogenesis.

Results: Using automated digital microscopy and image analysis (high content analysis, HCA), we found that DTG, EVG, and TDF decreased hiPSC-neuron viability, neurites, and synapses after 7 days of treatment.

Article Synopsis
  • The study analyzes work-family life courses from ages 16 to 42 in three British birth cohorts (1946, 1958, 1970) using multi-channel sequence analysis and logistic regression to assess psychological distress at ages 42/43 in men and women.
  • It hypothesizes that weaker employment ties and early transitions to partnerships and parenthood increase psychological distress risks, with expectations of this effect intensifying across the cohorts.
  • Findings indicate men and women with weaker long-term job connections experience more psychological distress, largely influenced by early life factors, with teen mothers showing increased distress in later cohorts that remains unexplained.

Even as the goal of social inclusion underpins health and social services for disabled youths, those with communication impairments continue to lead narrowly circumscribed lives. In this Canadian study, we combined visual methods and interviews with 13 Canadian youths who use augmentative and alternative communication (AAC) to understand how they make 'practical sense' of discourses of inclusion. Drawing on Bourdieu's theory of practice, we suggest: (i) participants' narratives reveal habitus - a socially constituted set of dispositions - that predispose them to accommodate the devalued social positions and constricted conditions of existence imposed on them; (ii) some forms of 'inclusion' perpetuate symbolic violence, as youths who use AAC internalise, as seemingly 'natural', dominant social norms and values that privilege 'normal' bodies; and (iii) although their practices primarily reproduced the status quo, youths in the study also worked at the margins to create locally produced forms of inclusion that attempted to transform the 'rules of the game'.

Research in the area of illicit substance use remains preoccupied with describing and analyzing the risks of people who use drugs (PWUD), however more recently there has been a drive to use a strengths-based or resilience approach as an alternative to investigating drug use. This leads us to ask: what can be known about PWUD from the point of view of resilience? The objective of this scoping review is to analyze how the concept of resilience is defined, operationalized, and applied in substance use research. Popular health, social science, psychology, and inter-disciplinary databases namely: SCOPUS, PUBMED, PsycINFO, and Sociological Abstracts were searched.

Rapid screening for enteric bacterial pathogens in clinical environments is essential for biosecurity. Salmonella found in veterinary hospitals, particularly Salmonella enterica serovar Dublin, can pose unique challenges for culture and testing because of its poor growth. Multiple Salmonella serovars including Dublin are emerging threats to public health given increasing prevalence and antimicrobial resistance.

The Javan rhinoceros ( Rhinoceros sondaicus) of Ujung Kulon National Park (UKNP) is the crown jewel of Indonesia's rich natural history. The park lies on a peninsula surrounded by coastline and agriculture-dominated landscapes. The invasion of water buffalo ( Bubalus bubalis) into the park carries a substantial health risk to the Javan rhinoceros and threatens plans to establish a new population outside of its only current range in UKNP.

Article Synopsis
  • Postchemotherapy cognitive impairment (PCCI) affects cancer patients treated with various chemotherapeutics, including tamoxifen (TAM), but the causes are not well understood.
  • Researchers aimed to create methods for testing chemicals’ effects on neuron function, using rat hippocampal neurons and exposure to compounds like forskolin (FSK) and TAM over several days.
  • The study found that FSK enhanced neuronal activity and synaptic protein expression, while TAM inhibited these functions, potentially contributing to PCCI development, and highlighted techniques for further investigating neurotoxic effects and therapeutics.

Background: Given the current policy emphasis in many Western societies on extending working lives, we investigated the health effects of being in paid work beyond state pension age (SPA). Until now, work has largely focused on the health of those who exit the labour force early.

Methods: Our data come from waves 2-4 of the English Longitudinal Study of Ageing, including the life history interview at wave 3.

Background: Given the acceleration of population ageing and policy changes to extend working lives, evidence is needed on the ability of older adults to work for longer. To understand more about the health impacts of work, this study examined the relationship between employment histories before retirement and trajectories of frailty thereafter.

Methods: The sample comprised 2765 women and 1621 men from the English Longitudinal Study of Ageing.

Background/objectives: Combining work and family responsibilities has previously been associated with improved health in mid-life, yet little is known about how these associations change over time (both biographical and historical) and whether this extends to body mass index (BMI) trajectories for British men and women. The purpose of this study was to investigate relationships between work-family life courses and BMI trajectories across adulthood (16-42 years) for men and women in three British birth cohorts.

Subjects/methods: Multiply imputed data from three nationally representative British birth cohorts were used-the MRC National Survey of Health and Development (NSHD; 1946 birth cohort, n=3012), the National Child Development Study (NCDS; 1958 birth cohort, n=9614) and the British Cohort Study (BCS; 1970 birth cohort, n=8140).

This article takes as its starting point the idea that re-emerging infectious disease has become a paradigmatic way of thinking about disease. The framing of infectious disease as a threat to global public health and economic security coincides with preemptive forms of control. A particular type of preemptive regulation is global pandemic influenza planning that entails the governing of an imminent, albeit uncertain, global health event.

Background: Previous studies have found generally better health among those who combine employment and family responsibilities; however, most research excludes men, and relies on subjective measures of health and information on work and family activities from only 1 or 2 time points in the life course. This study investigated associations between work-family life course types (LCTs) and markers of metabolic risk in a British birth cohort study.

Methods: Multichannel sequence analysis was used to generate work-family LCTs, combining annual information on work, partnership and parenthood between 16 and 42 years for men and women in the British National Child Development Study (NCDS, followed since their birth in 1958).
