Due to the COVID-19 pandemic, there has been a shift in focus towards controlling the spread of SARS-CoV-2, which has resulted in the neglect of traditional programs aimed at preventing healthcare-associated infections and combating antimicrobial resistance. The present work aims to characterize the colonization or infection with Acinetobacter baumannii of COVID-19 patients and to identify any clonality between different isolates. Specifically, data and resistance profiles of A. baumannii isolates were prospectively collected from patients recruited by the EPIRADIOCLINF project. Pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST) were used for molecular typing. Overall, we analyzed 64 isolates of A. baumannii from 48 COVID-19 patients. According to our analysis, we have identified the spread of a clonally related isolate, referred to as B. The PFGE pattern B includes four subtypes: B1 (consisting of 37 strains), B2 (11), B3 (5), and B4 (2). Furthermore, in the isolates that were examined using MLST, the most observed sequence type was ST/281. In terms of resistance profiles, 59 out of the total isolates (92.2%) were found to be resistant to gentamicin, carbapenems, ciprofloxacin, and tobramycin. The isolation and identification of A. baumannii from COVID-19 patients, along with the high levels of transmission observed within the hospital setting, highlight the urgent need for the implementation of effective prevention and containment strategies.

Skin diseases affect a considerable proportion of the population worldwide, with a substantial impact on quality of life. The power of certain foods, beverages, and dietary supplements for the primary prevention of these diseases remains poorly understood and is not widely disseminated. The aim of this umbrella review was to evaluate specific nutrients in the primary prevention of skin diseases. Manuscripts were extracted from four online databases (PubMed, Scopus, Web of Science, and Cochrane) using keywords and MeSH (Medical Subject Headings) terms. The inclusion criteria were general populations and high-risk but disease-free individuals, food and dietary supplementation intake, their effects on the primary prevention of skin diseases, and systematic reviews or meta-analyses. When performing a further search, other studies were included, but manuscripts regarding risk factors and diets were excluded. A total of six studies were included in this umbrella review, which covered a period between 2001 and 2023 and included a total of 9,229 participants, either in utero or aged 0－80 years old. The preventive effect of green tea catechins on ultraviolet radiation-induced erythema was highlighted, as well as the role of Lactobacillus probiotics in infant atopic eczema. Finally, niacinamide supplementation reduced the incidence of basal and squamous cell carcinoma (the major subtypes of non-melanoma skin cancer). Despite the small number of studies identified, the emerging evidence provided some insights into the primary prevention of certain skin diseases and may serve as a foundation for future studies.
