Gut microbial dynamics and cardiovascular outcomes are also shaped by biological sex. However, sex-specific responses to myocardial infarction (MI) that involve the gut microbiome and intestinal milieu remain poorly defined, particularly in older hosts. Here, we characterize gut microbiome structure and function alongside physiological and immune responses to MI across multiple...

These findings provide an opportunity to implement measures to improve communication and planning and to strengthen diagnostic infrastructure prior to future outbreaks.

Convergent mutations arose in regulatory genes classically associated with direct antipseudomonal antibiotic pressure, demonstrating that resistance architectures can be selected independent of target engagement and underscoring the potential for collateral resistance under antibiotic stress.

Engagement in HCV treatment may have positive spillover effects, reducing rates of other health outcomes and healthcare utilization. We aimed to examine such effects among PWID living with HCV.

In contrast, post-malaria fatigue syndrome resolved within three months. Mon, 18 May 2026 06:00:00 -0400 Recent publications from TDC/Clinical Epidemiology authors: Epidemiological and genomic features of chikungunya virus disease in travellers returning from Cuba, September 2025 to January 2026: a GeoSentinel analysis https://pubmed.ncbi.nlm.nih.gov/42141885/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20260517000658&v=2.20.0 During September 2025-January 2026, 111 travellers (61 female/50 male; median age: 53 years) who acquired chikungunya virus (CHIKV) in Cuba were reported to GeoSentinel. Upon return, 64.2% (70/109) were potentially viraemic. Only 8.2% (9/98) had received pre-travel consultations. The CHIKV was of East-Central-South Africa genotype, closely related to Brazilian strains. International travellers can serve as arboviral outbreak sentinels and, if viraemic, risk introducing CHIKV into areas with...

HIVST is more likely to engage 25-34-year-olds and men, who have historically been less likely to be aware of their HIV status. Our results can help understand patterns of use and support countries in optimizing their HIV testing services.

The ability to study human islets ex vivo has advanced our understanding of diabetes and aided in the development of novel therapeutics. However, for decades, very few laboratories had access to this critical resource and experiments on human islets were typically underpowered. More recently, multiple consortia around the world have started to enable islet biology at scale, enriching our understanding... Fri, 01 May 2026 06:00:00 -0400
