Semaglutide-Associated Gastric Pneumatosis.

Semaglutide, a glucagon-like peptide-1 receptor agonist, used for Type 2 diabetes mellitus and more recently for weight loss, often causes gastrointestinal adverse effects such as delayed gastric emptying and abdominal discomfort. Current literature has not described an associated case of gastric pneumatosis with semaglutide use. We report a 61-year-old man on semaglutide for 9 months with gastric pneumatosis.

Use of an Ethinyl Estradiol/Etonogestrel Vaginal Ring Alters Vaginal Microbial Communities in Women with HIV.

Background: HIV-1 antiretroviral therapy (ART) alters hormonal contraceptive levels delivered via intravaginal ring (IVR) in a regimen specific manner. We explored the role of the IVR on vaginal microbial communities, vaginal short chain fatty acids (SCFAs), vaginal HIV shedding, and the effect of vaginal microbes on hormone concentrations in cisgender women with HIV (WWH).

Methods: Vaginal microbes were assessed by 16S RNA sequencing of weekly vaginal swabs, vaginal SCFA by mass spectrometry, HIV-1 shedding by nucleic acid amplification on vaginal aspirates, and bacterial vaginosis by Nugent scoring from 74 participants receiving an etonorgestrel/ethinyl estradiol (ENG/EE) intravaginal ring while on no ART (N=25), efavirenz-based ART (N=25), or atazanavir-based ART (N=24).

Mouse innate resistance to infection is driven by early production of IFNγ by NK cells in response to parasite ligands.

Unlabelled: is capable of being transmitted by nearly all warm-blooded animals, and rodents are a major source of parasite dissemination, yet mechanisms driving its broad host range are poorly understood. Although a phylogenetically close relative of , differs from in that it does not infect mice and only infects a small number of ruminant and canine species. We recently showed that and grow similarly in mice during the first 24 h post-infection, but only induces an IFNγ-driven response within hours that controls the infection.

Effect of free liquid layer quantity on bacteria and protein adhesion to liquid infused polymers.

Liquid-infused polymers are recognized for their ability to repel foulants, making them promising for biomedical applications including catheter-associated urinary tract infections (CAUTIs). However, the impact of the quantity of free liquid layer covering the surface on protein and bacterial adhesion is not well understood. Here, we explore how the amount of free silicone liquid layer in infused silicone catheter materials influences the adhesion of bacteria and proteins relevant to CAUTIs.
