RESUMO
PURPOSE: There are currently no standard definitions for assessing the severity of Clostridioides difficile infection (CDI) in cancer patients. We evaluated the performance of scoring systems for severity and analyzed risk factors for mortality in a cancer cohort. METHODS: We conducted an observational study in patients with cancer and CDI. We calculated the incidence of hospital-onset (HO-CDI) and community-onset health-care facility associated (CO-HCFA-CDI) episodes. We classified severity using five prognostic scales and calculated sensitivity, specificity, positive (PPV), and negative predictive values (NPV) for mortality and intensive care unit (ICU) admission. In addition, multivariate regression was performed to assess variables associated with mortality. RESULTS: The HO-CDI and CO-HCFA-CDI incidence rates were 3.7 cases/10,000 patient-days and 1.9 cases/1,000 admissions, respectively. ESCMID criteria showed the higher sensitivity (97%, 95% CI; 85-100%) and NPV (98%, 95% CI; 85-100%), while ATLAS (≥ 6 points) had the highest specificity (95%, 95% CI; 90-98%) for 30-day all-cause mortality; similar performance was observed for ICU admission. Characteristics associated with fatal outcome were neutropenia (≤ 100 cells/ml) (aOR; 3.03, 95% CI; 1.05-8.74, p = 0.040), male gender (aOR; 2.90, 95% CI; 1.08-7.80, p = 0.034), high serum creatinine (aOR; 1.71, 95% CI; 1.09-2.70, p = 0.020), and albumin (aOR; 0.17, 95% CI; 0.07-0.42, p < 0.001). CONCLUSIONS: Some of the current scales may not be appropriate to discriminate severity in patients with cancer. The variables in this study associated with unfavorable outcomes could be evaluated in prospective studies to develop prognostic scores that identify susceptible patients, especially in immunocompromised populations.

PURPOSE: To evaluate the clinical and surgical outcomes among children with bicuspid aortic valve who underwent cardiac surgery. METHODS: This observational and retrospective study included patients with a diagnosis of bicuspid aortic valve who underwent cardiac surgery between January 1, 2003, and March 31, 2020. Demographic characteristics and perioperative conditions were described. RESULTS: One hundred and sixteen patients were included, with a mean age of 12.4 ± 4.2 years; 63.2% were male. The most frequent diagnosis was congenital aortic stenosis (23.5%), followed by connective tissue disorders (16%). Mechanical aortic prostheses were used in 87.7% of cases, with a mean size of 21 ± 2.6 mm. The main factors associated with mortality were valve prosthesis dysfunction (odds ratio [OR]: 12.44; 95% confidence interval [CI]: 1.05-147.48; p = .04) and reoperation (OR: 24.29; 95% CI: 1.03-570.08; p = .04). The overall survival was 87.9%, with better outcomes among those who did not undergo reoperation (Log Rank, p = .01). CONCLUSIONS: Outcomes after aortic valve replacement in children with bicuspid aortic valve are excellent in the short and long term, regardless of using mechanical or biological prostheses.

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%). Pulmonary venous obstruction (PVO) occurred in 32.1%. Risk factors associated with mortality were infracardiac TAPVC (odds ratio [OR]: 3.26; 95% confidence interval [CI]: 1.17-9.03; p = .02), PVO (OR: 2.56; 95% CI: 1.05-6.22; p = .03) and postoperative mechanical ventilation (OR: 1.005; 95% CI: 1.002-1.008; p = .01). Overall survival was 87.2%, with better outcomes in adolescents (100%), children (94.1%), mixed TAPVC (96%), and cardiac TAPVC (91.9%; p < .001). CONCLUSIONS: The survival of our institution after surgical correction of TAPVC is similar to that of other referral centers, where patients with infracardiac TAPVC and newborns worse outcomes. All patients must undergo a rigorous evaluation to determine an adequate repair strategy.

BACKGROUND: Breast surgery is considered a clean surgery. However, surgical-site infection (SSI) rates are currently higher than predicted. Postoperative drains remain in situ for several days, with inevitable bacterial colonization and increased SSI risk. METHODS: This randomized controlled trial from October 2016 to January 2018 analyzed patients undergoing breast cancer surgery. The patients were randomized to either the standard drain care group or the antiseptic dressing group (3M® Tegaderm® CHG). Drain samples taken on postoperative days (PODs) 7 and 14 were cultured as standardized in the laboratory. Colonization rates and SSI were compared between the two groups. RESULTS: The study enrolled 104 patients with 167 surgical drains. The patients' clinical characteristics were similar in the two groups, with no statistically significant differences. Bulb fluid cultures at postoperative week (POW) 1 were positive for 42.9% of the control group and 28.9% of the antiseptic group (p = 0.06). Cultures from the POW 2 assessment were positive for 79.7% of the control group versus 54.9% of the antiseptic group (p = 0.001). Cultures from drain tubes were positive for 79.8% of the control group and 50.7% of the antiseptic group (p = < 0.001). In 11 patients, an SSI developed, 3 (5.8%) from the intervention and 8 (15.4%) from the control procedure (p = 0.11). CONCLUSION: The study findings demonstrated that the use of antiseptics at the drain exit site significantly reduced bacterial colonization of the closed drainage system in breast cancer surgery. Semi-permeable occlusive chlorhexidine-impregnated dressings provide an opportunity to test simple, safe, and low-cost interventions that may reduce drain bacterial colonization and SSI after breast surgery.

BACKGROUND: Health care workers (HCWs) are occupationally exposed to severe acute respiratory syndrome coronavirus (SARS-CoV-2). This study aimed to characterize COVID-19 in HCWs at an oncology hospital in Mexico City over 2-years, identify factors associated with severity, and establish transmission dynamics. METHODS: This retrospective study included HCWs with confirmed COVID-19. Socio-demographic, clinical, and outcome data were retrieved from March 2020 to March 2022. We compared the proportion of HCWs affected in each wave. A survey on COVID-19 transmission dynamics was conducted in a subgroup. RESULTS: We included 1,058 workers. The risk of COVID-19 was higher during the Omicron odds ratio (OR 2.10, 95% confidence interval [CI] 1.77-2.50, P < .001). Age ≥41 years old (OR 6.32, 95% CI 2.4-16.62) and being administrative staff (OR 5.51, 95% CI 1.72-17.6) or medical staff (OR 6.82, CI 95% 1.77-26.23), compared to nursing staff, were associated with severity. Vaccination with ≥1 vaccine against SARS-CoV-2 was a protective factor for severe disease (OR 0.04, 95% CI 0.005-0.331). CONCLUSIONS: This study highlights the impact of COVID-19 on HCWs in a cancer hospital in Mexico City and the impact of vaccination as a protective factor against severity.
RESUMO
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.
RESUMO
Right atrial isomerism (RAI) is a complex entity with varying diagnostic and treatment outcomes due to its rarity. Treatment options range from palliative to corrective surgeries, resulting in heterogeneous outcomes. The aim of this study was to analyze the results obtained after cardiac surgery in patients with RAI. A retrospective study was conducted, including patients diagnosed with RAI who underwent cardiac surgery. Their follow-up was from 1 January 2010 to 31 March 2020. Demographic characteristics and perioperative conditions were described. Thirty-eight patients were included, the median age was 4 years (IQR 2-9.2) and 57.9% were men. The main diagnoses were atrioventricular canal (63.2%) and pulmonary stenosis (55.3%). The most common surgical procedures were modified Blalock-Taussig shunt (65.8%) and total cavopulmonary connection with an extracardiac conduit fenestrated without cardiopulmonary bypass (15.9%). We did not find any factors associated with negative outcomes in these patients. The overall survival was 86.8%, with a better outcome in those who did not require reintubation (log rank, p < 0.01). The survival of RAI was similar to other centers. Individuals with RAI should be evaluated rigorously to determine an adequate repair strategy, considering high morbidity and mortality.
RESUMO
Background: In recent decades, adults living with congenital heart disease (ACHD) have improved their survival, thus increasing their predisposition to the onset of cardiometabolic risk factors and chronic health conditions. Objectives: The purpose of this study was to describe cardiometabolic risk profiles in the ACHD population and their relationship to congenital heart disease (CHD) lesion complexity. Methods: We performed a cross-sectional study from ACHD in a third-tier referral center in Mexico City. The association between cardiometabolic risk factors and CHD complexity was estimated using logistic regression models. Results: Our study cohort included 1,171 ACHD patients (median age: 31 [IQR: 23.2-42.7] years, male 63.6%). Cardiac diagnosis was classified as mild (44.9%), moderate (37.8%), and severe (17.2%) CHD complexity. Low high-density lipoprotein cholesterol (55%) was the most common cardiometabolic risk factor; followed by insulin resistance (54.5%) and prediabetes (52.4%). Patients with mild and moderate CHD had a higher prevalence of obesity and metabolic syndrome, while patients with severe CHD had a higher prevalence of hyperuricemia and subclinical hypothyroidism. In the logistic regression analysis, the severity of CHD was associated with higher odds of hyperuricemia (moderate CHD, OR: 1.87; 95% CI: 1.20-2.93; P = 0.010; severe CHD, OR: 2.75; 95% CI: 1.64-4.62; P < 0.001) and lower risks of metabolic syndrome (OR: 0.61; 95% CI: 0.41-0.91; P = 0.010), prediabetes (OR: 0.58; 95% CI: 0.42-0.81; P < 0.001), and arterial hypertension (OR: 0.49; 95% CI: 0.33-0.74; P < 0.001) compared with mild CHD complexity. Conclusions: We observed high rates of cardiometabolic risk factors in Mexican ACHD patients and these risk profiles varied by CHD lesion complexity. These results highlight the need for ongoing metabolic health surveillance in the ACHD population.
RESUMO
INTRODUCTION: Clostridioides difficile infection (CDI) is recognized as the leading cause of nosocomial diarrhea. This study describes CDI's clinical characteristics, risk factors, and outcomes in the cancer population. METHODS: We conducted a case-control study on cancer patients from 2015-2018 at the Instituto Nacional de Cancerologia in Mexico. CDI case was defined as diarrhea episode and positive polymerase chain reaction (PCR) for toxigenic strains. Controls were cancer diagnosis-matched patients with diarrhea and negative PCR. Healthcare Facility-Onset (HO-CDI) and Community-Onset, Healthcare Facility-Associated (CO-HCFA-CDI) rates were calculated. For assessing associations, univariate and multivariate logistic regression analyses were conducted. RESULTS: We included 148 CDI cases and 148 controls. The CDI rate was 4.1 per 10,000 patient-days and 2.1 per 1,000 patient admissions for HO-CDI and CO-HCFA-CDI episodes, respectively. Clinical characteristics associated with CDI were fever, abdominal pain, and ≥4 episodes of diarrhea/24h. Previous use of proton pump inhibitors (P=.003), fluoroquinolones (P=.016), and cephalosporins (P=.026) increased the risk for CDI acquisition, while higher age (P=.022) and male gender (P=.015) were related to severe episodes. Thirty-day all-cause mortality was higher among CDI patients (18%) than controls (9%). CONCLUSION: The CDI rate was lower compared to other series. The incidence of CO-HCFA-CDI episodes increased, and HO-CDI cases decreased from 2016 to 2018. Risk factors for acquisition and severe infection were similar to those reported in non-cancer populations.
RESUMO
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.

The epidemiology of lymphomas has changed since the use of antiretroviral therapy. The incidence of Non-Hodgkin Lymphomas (NHL) has significantly decreased in high income countries but not in low and middle-income countries where AIDS-related events remain high. This observational study describes the characteristics, infectious complications and main outcomes of patients diagnosed with HIV and lymphoma at the Instituto Nacional de Cancerología.All adults >18 years diagnosed with HIV and lymphoma from January 2010 to December 2017 were included. Information on HIV and lymphoma was collected, as well as the occurrence of co-infections at diagnosis and during therapy. Multiple regression was done with NHL patients to evaluate independent variables associated to death.One hundred fifty three patients were included: 127 patients with NHL (83%) and 26 (17%) with Hodgkin lymphoma (HL). Of the NHL, 49 (38%) were diffuse large B cell Lymphomas (DLBCL), 35 (27%) plasmablastic, 28 (23%) Burkitt, 10 (8%) primary DLBCL of Central Nervous system, 3 (2%) T-cell lymphomas, and 2 (2%) pleural effusion lymphoma. Most patients were diagnosed in an advanced stage: 70% of NHL had a high International Prognostic Index (IPI); 68% of patients had <200âcells/mm. Almost 25% of NHL patients had an opportunistic infection at lymphoma diagnosis. During chemotherapy, 60% of all patients presented with at least 1 serious non-opportunistic infectious complication, and 50% presented 2 or more infectious complications, mostly bacterial infections. Thirty six percent of NHL and 23% of HL died. After adjusting for confounders, the variables associated with death were IPI and lymphoma type.HIV positive patients with lymphoma in our institution are diagnosed with an advanced stage and a high burden of infections complications. Death remains high and the variables strongly associated with death are those related to lymphoma prognosis such as lymphoma type and IPI.

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 highlights the importance of adhering to preventive measures, including contact isolation, when admitting patients with draining wounds who have been hospitalized in other institutions.
