Healthcare practitioners as accomplices: a qualitative study of gender affirmation in a context of ambiguous regulation in Indonesia.

Background: The World Professional Association for Transgender Health guidelines Standards of Care 8 draw on ethical arguments based on individual autonomy, to argue that healthcare and other professionals should be advocates for trans people. Such guidelines presume the presence of medical services for trans people and a degree of consensus on medical ethics. Very little is known, however, about the ethical challenges associated with both providing and accessing trans healthcare, including gender affirmation, in the Global South.

Moving beyond species: fungal function in house dust provides novel targets for potential indicators of mold growth in homes.

Background: Increased risk of asthma and other respiratory diseases is associated with exposures to microbial communities growing in damp and moldy indoor environments. The exact causal mechanisms remain unknown, and occupant health effects have not been consistently associated with any species-based mold measurement methods. We need new quantitative methods to identify homes with potentially harmful fungal growth that are not dependent upon species.

Making waves: Intelligent phage cocktail design, a pathway to precise microbial control in water systems.

Current practices in water and wastewater treatment to control unwanted microbes have led to new problems, including health effects from disinfection byproducts, growth of opportunistic pathogens resistant to residual disinfectants (e.g., chlorine), and antibiotic resistance.

Adult sex change leads to extensive forebrain reorganization in clownfish.

Background: Sexual differentiation of the brain occurs in all major vertebrate lineages but is not well understood at a molecular and cellular level. Unlike most vertebrates, sex-changing fishes have the remarkable ability to change reproductive sex during adulthood in response to social stimuli, offering a unique opportunity to understand mechanisms by which the nervous system can initiate and coordinate sexual differentiation.

Methods: This study explores sexual differentiation of the forebrain using single nucleus RNA-sequencing in the anemonefish Amphiprion ocellaris, producing the first cellular atlas of a sex-changing brain.

Spatially resolved cell atlas of the teleost telencephalon and deep homology of the vertebrate forebrain.

The telencephalon has undergone remarkable diversification and expansion throughout vertebrate evolution, exhibiting striking variations in structural and functional complexity. Nevertheless, fundamental features are shared across vertebrate taxa, such as the presence of distinct regions including the pallium, subpallium, and olfactory structures. Teleost fishes have a uniquely "everted" telencephalon, which has confounded comparisons of their brain regions to other vertebrates.

Benchmarking informatics approaches for virus discovery: caution is needed when combining identification methods.

Unlabelled: Understanding the ecological impacts of viruses on natural and engineered ecosystems relies on the accurate identification of viral sequences from community sequencing data. To maximize viral recovery from metagenomes, researchers frequently combine viral identification tools. However, the effectiveness of this strategy is unknown.

Natural variation in oxytocin receptor signaling causes widespread changes in brain transcription: a link to the natural killer gene complex.

Oxytocin (OXT) is a highly conserved neuropeptide that modulates social cognition, and variation in its receptor gene () is associated with divergent social phenotypes. The cellular mechanisms connecting genotype to social phenotype remain obscure. We exploit an association between polymorphisms and striatal-specific OXTR density in prairie voles to investigate how OXTR signaling influences the brain transcriptome.

Cellular profiling of a recently-evolved social behavior in cichlid fishes.

Social behaviors are diverse in nature, but it is unclear how conserved genes, brain regions, and cell populations generate this diversity. Here we investigate bower-building, a recently-evolved social behavior in cichlid fishes. We use single nucleus RNA-sequencing in 38 individuals to show signatures of recent behavior in specific neuronal populations, and building-associated rebalancing of neuronal proportions in the putative homolog of the hippocampal formation.

Spatially resolved cell atlas of the teleost telencephalon and deep homology of the vertebrate forebrain.

The telencephalon has undergone remarkable diversification and expansion throughout vertebrate evolution, exhibiting striking differences in structural and functional complexity. Nevertheless, fundamental features are shared across vertebrate taxa, such as the presence of distinct regions including the pallium, subpallium, and olfactory structures. Teleost fishes have a uniquely 'everted' telencephalon, which has made it challenging to compare brain regions in fish to those in other vertebrates.

Teneurin trans-axonal signaling prunes topographically missorted axons.

Building precise neural circuits necessitates the elimination of axonal projections that have inaccurately formed during development. Although axonal pruning is a selective process, how it is initiated and controlled in vivo remains unclear. Here, we show that trans-axonal signaling mediated by the cell surface molecules Glypican-3, Teneurin-3, and Latrophilin-3 prunes misrouted retinal axons in the visual system.

A snapshot of the global drinking water virome: Diversity and metabolic potential vary with residual disinfectant use.

Viruses are important drivers of microbial community ecology and evolution, influencing microbial mortality, metabolism, and horizontal gene transfer. However, the effects of viruses remain largely unknown in many environments, including in drinking water systems. Drinking water metagenomic studies have offered a whole community perspective of bacterial impacts on water quality, but have not yet considered the influences of viruses.

Chasing targets in a pandemic: The impact of COVID-19 on HIV outreach workers for MSM (men who have sex with men) in Jakarta, Indonesia.

The COVID-19 pandemic has had a significant impact on HIV services globally, including community-based outreach programmes. This article draws on a qualitative study of HIV outreach workers for men who have sex with men (MSM) in Jakarta, Indonesia undertaken between July and September 2020. The research documented the impact of the COVID-19 pandemic on HIV outreach programmes for MSM based on interviews, focus group discussions and video diaries collected from outreach workers.

DNA Sequence-Based Approach for Classifying the Mold Status of Buildings.

Dampness or water damage in buildings and human exposure to the resultant mold growth is an ever-present public health concern. This study provides quantitative evidence that the airborne fungal ecology of homes with known mold growth ("moldy") differs from the normal airborne fungal ecology of homes with no history of dampness, water damage, or visible mold ("no mold"). Settled dust from indoor air and outdoor air and direct samples from building materials with mold growth were examined in homes from 11 cities across dry, temperate, and continental climate regions within the United States.

Humidity and Deposition Solution Play a Critical Role in Virus Inactivation by Heat Treatment of N95 Respirators.

Supply shortages of N95 respirators during the coronavirus disease 2019 (COVID-19) pandemic have motivated institutions to develop feasible and effective N95 respirator reuse strategies. In particular, heat decontamination is a treatment method that scales well and can be implemented in settings with variable or limited resources. Prior studies using multiple inactivation methods, however, have often focused on a single virus under narrowly defined conditions, making it difficult to develop guiding principles for inactivating emerging or difficult-to-culture viruses.

Understanding the challenges faced in community-based outreach programs aimed at men who have sex with men in urban Indonesia.

Unlabelled: Background Community-based outreach programs play an important role in the provision of HIV testing, treatment and health care for men who have sex with men (MSM) in Indonesia. However, qualitative studies of community-based HIV programs have mostly focused on clients rather than on outreach workers (OW). The experiences of MSM peer OW provide insights into how to extend and improve community involvement in HIV programs in Indonesia.

Ten questions concerning the implications of carpet on indoor chemistry and microbiology.

Carpet and rugs currently represent about half of the United States flooring market and offer many benefits as a flooring type. How carpets influence our exposure to both microorganisms and chemicals in indoor environments has important health implications but is not well understood. The goal of this manuscript is to consolidate what is known about how carpet impacts indoor chemistry and microbiology, as well as to identify the important research gaps that remain.

Early treatment response in psychotherapy for depression and personality disorder: links with core conflictual relationship themes.

Depressed personality disorder patients showing an early rapid response (or sudden gain) in psychotherapy have better outcomes. Early responders are five times more likely to recover, despite equivalent ratings of working alliance. We explored core conflictual relationship themes (CCRTs) of early responders compared to others to further elucidate process-outcome links.

Degradation of phthalate esters in floor dust at elevated relative humidity.

Emerging investigator series: Phthalate esters are present at elevated concentrations in floor dust, and resuspension of dust represents a major source for human exposure to chemicals. Biodegradation of phthalates occurs in aquatic systems and soils but has not been demonstrated in house dust. The goal of this study was to quantify indoor phthalate ester degradation through both biotic and abiotic mechanisms.

Evaluation of cell culture-grown Bartonella antigens in immunofluorescent antibody assays for the serological diagnosis of bartonellosis in dogs.

Background: Because of poor sensitivity and questionable specificity of immunofluorescent antibody assays (IFAs), serological diagnosis of Bartonella species infections in dogs remains challenging. Despite limitations, IFA testing is the historical "gold standard" for Bartonella serodiagnosis in animals and humans. Because most diagnostic laboratories test against only 1 or 2 Bartonella spp.

The reestablishment of microbial communities after surface cleaning in schools.

Aims: The goal of this study was to quantify the indoor microbiome dynamics of bacterial and fungal communities on school desk surfaces during a cleaning intervention.

Methods And Results: Quantitative PCR and DNA sequenced-based approaches were employed to describe microbial community dynamics on ten desk surfaces, spread across three schools, located in the Northeast region of the United States. Six samples were taken from each desk, one precleaning, and five postcleaning at 30 min, 1, 3, 7 and 21 days.

Gene expression of indoor fungal communities under damp building conditions: Implications for human health.

Dampness and visible mold growth in homes are associated with negative human health outcomes, but causal relationships between fungal exposure and health are not well established. The purpose of this study was to determine whether dampness in buildings impacts fungal community gene expression and how, in turn, gene expression may modulate human health impacts. A metatranscriptomic study was performed on house dust fungal communities to investigate the expression of genes and metabolic processes in chamber experiments at water activity levels of 0.
