Improving tobacco cessation interventions in hospitals: Pre-post evaluation of an innovative health systems intervention in Catalonia (Spain).

This study measured changes in healthcare professionals' (HCPs) performance in tobacco cessation intervention before and 6 months after a health system intervention. The intervention involved exposure to online training for staff and the implementation of a structured organizational change-level practice model that included some strategies, comprising establishing tobacco cessation steering groups with champions in each hospital, developing tailored protocols and guidelines within each organization, conducting on-site workshops for clinicians, and creating posters and pocket materials summarizing the intervention. Pre-post evaluation in four hospitals in Barcelona province (Catalonia, Spain).

Vaginal microbes alter epithelial transcriptome and induce epigenomic modifications providing insight into mechanisms for susceptibility to adverse reproductive outcomes.

The cervicovaginal microbiome is highly associated with women's health, with microbial communities dominated by species considered optimal. Conversely, a lack of lactobacilli and a high abundance of strict and facultative anaerobes, including , have been associated with adverse reproductive outcomes. However, how host-microbial interactions alter specific molecular pathways and impact cervical and vaginal epithelial function remains unclear.

Extracellular vesicles alter trophoblast function in pregnancies complicated by COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and resulting coronavirus disease (COVID-19) causes placental dysfunction, which increases the risk of adverse pregnancy outcomes. While abnormal placental pathology resulting from COVID-19 is common, direct infection of the placenta is rare. This suggests that pathophysiology associated with maternal COVID-19, rather than direct placental infection, is responsible for placental dysfunction and alteration of the placental transcriptome.
