Objective To describe the clinical features, outcomes, and molecular epidemiology of an outbreak of multidrug resistant (MDR) A. baumannii. Methods We performed a retrospective analysis of all MDR A. baumannii isolates recovered during an outbreak from 2011 to 2015 in a tertiary care cancer hospital. Cases were classified as colonized or infected. We determined sequence types following the Bartual scheme and plasmid profiles. Results There were 106 strains of A. baumannii isolated during the study period. Sixty-six (62.3%) were considered as infection and 40 (37.7%) as colonization. The index case, identified by molecular epidemiology, was a patient with a drain transferred from a hospital outside Mexico City. Ninety-eight additional cases had the same MultiLocus Sequence Typing (MLST) 758, of which 94 also had the same plasmid profile, two had an extra plasmid, and two had a different plasmid. The remaining seven isolates belonged to different MLSTs. Fifty-three patients (50%) died within 30 days of A. baumanniii isolation: 28 (20%) in colonized and 45 (68.2%) in those classified as infection (p<0.001). In multivariate regression analysis, clinical infection and patients with hematologic neoplasm, predicted 30-day mortality. The molecular epidemiology of this outbreak showed the threat posed by the introduction of MDR strains from other institutions in a hospital of immunosuppressed patients and

Purpose: The aim of the study was to analyze the surgical outcome of patients with total anomalous pulmonary venous connection (TAPVC) who underwent cardiac surgery.Methods: A retrospective study was carried out. Patients with diagnosis of TAPVC undergoing cardiac surgery at the National Institute of Cardiology Ignacio Chávez, from January 1, 2003 and June 30, 2019 were included. Descriptive statistics were calculated, as well as a bivariate analysis of the variables associated with mortality.A logistic regression model was included to determine risk factors associated with the main outcome and survival was analyzed using the Kaplan-Meier method.Results: A total of 5314 patients diagnosed with congenital heart disease (CHD) underwent surgery, 414 (7.8%) were patients with TAPVC, with an average age of 17.1 ± 34.6 months, 58.2% were male. It was frequent in infants (61.6%) and preschool (19.6%). Predominant type was supracardiac TAPVC (47.4%

The identification of carbapenemase-producing Enterobacterales and Pseudomonas aeruginosa is important for treating and controlling hospital infections. The recommended methods for their identification require a long waiting time, technical training, and expertise. Lateral flow immunoassays such as NG-Test CARBA 5® overcome these needs. We analyzed 84 clinical isolates of carbapenem-resistant Enterobacterales and P. aeruginosa from four different hospitals in a two-year period. Antimicrobial resistance patterns were confirmed with the broth dilution method. Evaluation of KPC, VIM, NDM, IMP, and OXA-48-like enzymes was performed and compared to NG-Test CARBA 5 and phenotypic assays. Enterobacterales represented 69% of isolates and P. aeruginosa represented 31%. Carbapenemase-producing strains were 51 (88%) of Enterobacterales and 23 (88.4%) of P. aeruginosa; 20 (34%) and 23 (88%) were Class B ß-lactamases, respectively. The NG-Test CARBA 5® assay for Enterobacterales showed high sensitivity (98%), specificity (100%), and PPV (100%); however, it did not for P. aeruginosa. The Kappa concordance coefficient was 0.92 for Enterobacterales and 0.52 for P. aeruginosa. NG-Test CARBA 5® is a fast and easy-to-use assay. In Enterobacterales, we found excellent agreement in our comparison with molecular tests. Despite the low agreement in P. aeruginosa, we suggest that this test could be used as a complementary tool.

Severe acute respiratory syndrome coronavirus 2, the etiologic agent of coronavirus disease 2019, has caused more than 160 million infections globally. The experience of our department showed that the execution of a strict surgery protocol, universal severe acute respiratory syndrome coronavirus 2 screening, surgical prioritization, and an orderly reactivation of the cardiac surgery program is a feasible way to keep congenital heart diseases surgery program.
