RESUMEN
OBJECTIVE: Evaluate clinical competence of a mexican resident physicians sample for diagnosis and treatment of Chagas disease. MATERIAL AND METHODS: Cross-sectional and analytic study in 122 resident physicians of epidemiology, family medicine and internal medicine specialty, assigned to a third level medical unit from Guadalajara, Jalisco, Mexico, taking a sample for convenience. An instrument was designed and validated for to evaluate clinical competence in five dimensions: risk factors identification, clinical data identification, diagnostic test interpretation, diagnostic integration and therapeutic resources utilization; that classified competence level in four strata: random defined, low, medium and high, with 89% of reliability accord to Kunder-Richardson test. Descriptive and no parametric inferential statistics were obtained. RESULTS: A total of 122 physicians, 55.7% males (n = 68) and 44.3% females (n = 54). Random defined clinical competence 4.9% (n = 6), low 49.2% (n = 60), medium 44.3% (n = 54) and high 1.6% (n = 2). Median significantly higher in epidemiologists (p = 0.03). CONCLUSIONS: Improve clinical competence level of resident physicians for diagnosis and treatment of Chagas disease is necessary. Intervention studies are required.

BACKGROUND: Leukocytes contained in the allogeneic packed red blood cell (PRBC) are the cause of certain adverse reactions associated with blood transfusion. Leukoreduction consists of eliminating leukocytes in all blood products below the established safety levels for any patient type. In this systematic review, we appraise the clinical effectiveness of allogeneic leukodepleted (LD) PRBC transfusion for preventing infections and death in patients undergoing major cardiovascular surgical procedures. METHODS: We searched randomized controlled trials (RCT), enrolling patients undergoing a major cardiovascular surgical procedure and transfused with LD-PRBC. Data were extracted, and risk of bias was assessed according to Cochrane guidelines. In addition, trial sequential analysis (TSA) was used to assess the need of conducting additional trials. Quality of the evidence was assessed using the GRADE approach. RESULTS: Seven studies met the eligibility criteria. Quality of the evidence was rated as moderate for both outcomes. The risk ratio for death from any cause comparing the LD-PRBC versus non-LD-PRBC group was 0.69 (CI 95% = 0.53 to 0.90; I 2 = 0%). The risk ratio for infection in the same comparison groups was 0.77 (CI 95% = 0.66 to 0.91; I 2 = 0%). TSA showed a conclusive result in this outcome. CONCLUSIONS: We found evidence that supports the routine use of leukodepletion in patients undergoing a major cardiovascular surgical procedure requiring PRBC transfusion to prevent death and infection. In the case of infection, the evidence should be considered sufficient and conclusive and hence indicated that further trials would not be required.
