A retrospective cohort study was conducted with data from 150 patients from a Peruvian hospital between the years 2010 to 2020. Characteristics and survival (Kaplan-Meier method) were described. The mean age was 48.3 years, 130 participants (86.7%) were women and the most frequent histologic type was papillary 94.6%. Of the participants, 74.2% had TNM stage I, 70.7% had total thyroidectomy and 68.7% received radioactive iodine. Overall survival at 5 years was 89.3%, being lower in those with TNM stage IV and higher in those who used radioactive iodine.

The presence of antibiotic resistance genes in bacteria isolated from common flies is a potential public health hazard because it facilitates the presence and spread of antibiotic resistance genes in the environment. Main findings. Thirty-eight bacterial strains identified in 14 species were isolated from within the fly bodies, of which 31 strains showed resistance to carbapenems and 26 strains showed resistance to colistin. Seven bacterial strains showed carbapenem resistance genes and one Escherichia coli strain had resistance to KPC, OXA-48 and mcr-1. Implications. This is the first report of antibiotic resistance genes in bacteria carried by common flies in Peru. The objective was to determine the presence of carbapenem resistance genes and plasmid resistance to colistin (mcr-1) in bacteria isolated from Musca domestica in a garbage dump near a hospital in Lima, Peru. Bacteria with phenotypic resistance to carbapenemics were isolated on CHROMagar mSuperCARBATM medium and colistin resistance profiling was performed using the colistin disk elution method. Detection of blaKPC, blaNDM, blaIMP, blaOXA-48, blaVIM and mcr-1 genes was performed by conventional PCR. The antimicrobial susceptibility profile was determined using the automated MicroScan system. We found that 31/38 strains had phenotypic resistance to carbapenemics and 26/38 strains had phenotypic resistance to colistin with a minimum inhibitory concentration ≥ 4 µg/ml.

Our results can inform strategies for prevention and management of COVID-19 in pregnant women, as well as guide the development of health policies aimed at protecting maternal and neonatal health during the pandemic.

Twelve pregnant women who met the inclusion criteria were included.
