We analyzed for the first time the concentration of potentially toxic trace elements Hg, As, Pb, Cr and Se and POPs (PCBs and OCPs) in tissues of 41 grey seal pups (Halichoerus grypus) stranded on the shores of the Gulf of Riga. Lanugo was the sample with the highest concentrations of all trace elements except Hg. The concentrations found in this biological matrix appeared as follows: Hg (2.

The cefazolin inoculum effect (CzIE) has been associated with poor clinical outcomes in patients with methicillin-susceptible (MSSA) infections. We aimed to investigate the point prevalence of the CzIE among nasal colonizing MSSA isolates from ICU patients in a multicenter study in Colombia (2019-2023). Patients underwent nasal swabs to assess for colonization on admission to the ICU, and some individuals had follow-up swabs.

Our aim was to carry out a cross-sectional study of the prevalence of mental health symptoms in HCWs in Colombia.
Methods: A cross-sectional web-survey study was performed during the COVID-19 pandemic mid-2021 including HCWs in two hospitals in Colombia.
Article Synopsis
- Bacteria from the genus Brucella cause brucellosis, a serious disease affecting both animals and humans, and have been controversially merged with other unrelated bacterial species based on genomic findings.
- Researchers argue this merger is inappropriate due to lack of thorough phylogenetic analysis and exclusion of expert opinions in brucellosis.
- They warn that combining these groups could lead to confusion and risks in public health, particularly impacting those dealing with brucellosis in under-resourced regions, and call for keeping the Brucella genus distinct.
