The fungal microbiota modulate neonatal oxygen-induced lung injury.

Background: The immature lungs of very preterm infants are exposed to supraphysiologic oxygen, contributing to bronchopulmonary dysplasia (BPD), a chronic lung disease that is the most common morbidity of prematurity. While the microbiota significantly influences neonatal health, the relationship between the intestinal microbiome, particularly micro-eukaryotic members such as fungi and yeast, and lung injury severity in newborns remains unknown.

Results: Here, we show that the fungal microbiota modulates hyperoxia-induced lung injury severity in very low birth weight premature infants and preclinical pseudohumanized and altered fungal colonization mouse models.

Harnessing Big Heterogeneous Data to Evaluate the Potential Impact of HIV Responses Among Key Populations in Sub-Saharan Africa: Protocol for the Boloka Data Repository Initiative.

Background: In South Africa, there is no centralized HIV surveillance system where key populations (KPs) data, including gay men and other men who have sex with men, female sex workers, transgender persons, people who use drugs, and incarcerated persons, are stored in South Africa despite being on higher risk of HIV acquisition and transmission than the general population. Data on KPs are being collected on a smaller scale by numerous stakeholders and managed in silos. There exists an opportunity to harness a variety of data, such as empirical, contextual, observational, and programmatic data, for evaluating the potential impact of HIV responses among KPs in South Africa.

Association between homelessness and PrEP uptake among men who have sex with men: Results from the American Men's Internet Survey, 2017-2021.

Background: Gay, bisexual, and other men who have sex with men (GBMSM) are disproportionately affected by housing insecurity across the US. This study examined the association between homelessness and uptake of pre-exposure prophylaxis (PrEP) for HIV prevention among GBMSM in the United States and investigated the modifying effect of injection drug use.

Methods: 47,750 cisgender GBMSM who participated in the American Men's Internet Survey from 2017 to 2021 and who self-reported not living with HIV were included in this secondary, cross-sectional analysis.

The collective experience of moral distress: a qualitative analysis of perspectives of frontline health workers during COVID-19.

Background: Moral distress is reported to be a critical force contributing to intensifying rates of anxiety, depression and burnout experienced by healthcare workers. In this paper, we examine the moral dilemmas and ensuing distress personally and collectively experienced by healthcare workers while caring for patients during the pandemic.

Methods: Data are drawn from free-text responses from a cross-sectional national online survey of Australian healthcare workers about the patient care challenges they faced.

A Y chromosome-linked genome editor for efficient population suppression in the malaria vector Anopheles gambiae.

Genetic control - the deliberate introduction of genetic traits to control a pest or vector population - offers a powerful tool to augment conventional mosquito control tools that have been successful in reducing malaria burden but that are compromised by a range of operational challenges. Self-sustaining genetic control strategies have shown great potential in laboratory settings, but hesitancy due to their invasive and persistent nature may delay their implementation. Here, instead, we describe a self-limiting strategy, designed to have geographically and temporally restricted effect, based on a Y chromosome-linked genome editor (YLE).
