Median enterococci counts of beach water samples gradually increased at statistically significant levels (χ2: 26.53, df: 4; p<0.0001) with increasing proximity to river influx. The difference in proportion of antibiotic resistant enterococci in beach water and river water samples was statistically significant (p<0.05) for the tested antibiotics with river isolates generally presenting higher resistance frequencies. Virulence genes cyl, esp, gelE and asa were detected at varying frequencies (7.32%, 21.95%, 100% and 63.41% respectively) among river isolates. On the other hand, the prevalence of these genes was lower (0%, 20%, 67.27% and 41.82% respectively) among beach water isolates. Multi-Locus-Sequence-Typing analysis of Enterococcus faecalis presented four sequence types (ST) one of which shared six out of seven tested loci with ST6, a member of the clonal complex of multi-drug resistant strains associated with hospital outbreaks.

Department of Anesthesiology, Third Xiangya Hospital, Central South University, Changsha, Hunan, P.R. China.
Background: Hand-foot syndrome (HFS) and oral mucositis (OM) are common adverse events during cancer chemotherapy and can significantly decrease patients' quality of life and chemotherapy adaptation, however, prevention strategies of these complications yet to be established.
Methods: Patients with stage I-III breast cancer, who had surgery and needed pegylated liposomal doxorubicin (PLD)-based adjuvant chemotherapy were screened, recruited and randomly assigned to receive either probiotics or placebo (three capsules, twice/day) treatment during the course of chemotherapy from Nov. 2019 to Aug.

Objectives: The detection rate of vancomycin-resistant Enterococcus faecium (VREfm) displayed a dramatically increase in Guangdong, China from 2021 to 2023, for which the molecular epidemiology and genomic characteristics remain largely unexplored. In this study, we investigated the genetic features and epidemiology of VREfm isolates in Guangdong.
Methods: A total of 54 Guangdong VREfm isolates were collected from three tertiary hospitals in Guangdong.

In this study, the blood culture results of patients aged >65 years who were admitted to the cardiology intensive care unit in a training and research hospital and who had positive blood cultures within the first 48 hours were evaluated. This was a retrospective, observational and nonrandomized study. Patient data at the time of the blood culture were included in the study.
