Friends to remember: innate immune memory regulation by the microbiota.

Innate immune memory (IIM) is the process by which, upon a primary challenge, innate immune cells alter their epigenetic, transcriptional, and immunometabolic profiles, resulting in modified secondary responses. Unlike infections or other immune-system-related diseases, the role of IIM in nonpathogenic contexts is less understood. An increasing body of research has shown that normal microbiota members or their metabolic byproducts induce alternative memory phenotypes, suggesting that memory cells contribute to homeostasis in mucosal areas.

Trends in Screening for Social Risk in US Physician Practices.

Importance: A wealth of research on screening for social risks in health care has emerged, but evidence is lacking on how social risk screening among physician practices has changed over time.

Objectives: To evaluate trends in screening for social risks among US physician practices and examine practice characteristics associated with adoption of social risk screening.

Design, Setting, And Participants: The main analysis used a repeated cross-sectional design to analyze results from US physician practices that completed the National Survey of Healthcare Organizations and Systems, a nationally representative survey of physician practices, in 2017 and 2022.

[Identification and antibiotic susceptibility of Aeromonas spp. in a University Hospital in the city of Buenos Aires].

Aeromonas spp. are opportunistic pathogens that cause both intra- and extraintestinal infections. The objective of this work was the phenotypic and genotypic characterization of a collection of Aeromonas strains, in addition to determining their sensitivity to different antimicrobials.

New Insights on the Diversity, Ecology and Genetic Population Structure of spp. from Fish and Cetacean Hosts from Northeast Atlantic Waters.

In the last 25 years, nematode parasites of the genus have attracted international attention from various socio-economic sectors, with serious concern about the impact of these parasites on seafood quality and safety, and public health (related to both zoonoses and allergy). A knowledge-based understanding of the population structure of spp. is useful to provide valuable data about the infection dynamics, host specificity and its ability to adapt to local environments and to climate change by adapting to the food-web structure.
