Abstract Objective: The aim of this study is to translate and validate the Nutritional Pathway for Infants with Congenital Heart Disease before Surgery British nutritional protocol into Brazilian Portuguese and test its clinical feasibility for specialized clinicians in Brazilian hospitals. Method: The translation and validation process followed strict methodological standards over the following steps: 1) initial translation; 2) synthesis; 3) back-translation; 4) expert committee content validation, and pre-test clinical feasibility with 30 health professionals. Data were collected through the Research Electronic Data Capture software data system, and then extracted and analyzed through statistical analysis software. Results: The culturally adapted version was considered equivalent to the original. In the first round, 82% agreement was achieved, and after consensus, there was 100% agreement among the experts. Regarding the ease of use of the protocol in clinical practice, the instrument obtained a minimum agreement rate of 93.4% and a 0.92 content validity index. Conclusions: The results indicate that the instrument adapted to Brazilian Portuguese has high content validity, and high reliability among the experts, suggesting a high level of accuracy of the instrument and cultural adaptation for Brazilian culture and medical systems. It was easily understandable by health professionals, as well as simple to apply in clinical practice. The Nutritional protocol for preoperative infants with congenital heart disease can reproduce the outcomes found in the pilot of this instrument carried out in the United Kingdom, which may promote better pre-surgical nutritional status for infants with congenital heart disease in Brazil.

Abstract Introduction: Coronary artery bypass grafting (CABG) performed with and without cardiopulmonary bypass (CPB) support has been widely discussed in the literature. However, little is known about the outcomes of those techniques in Brazil. This study aims at exploring 30-day mortality and morbidity outcomes of on- and off-pump isolated CABG in a large sample from Southern Brazil. Methods: A single-center cohort with 1,767 patients undergoing isolated CABG (January 2013 - December 2018) was initially evaluated. Patients undergoing off-pump (N=397) and on-pump (N=1,370) CABG were identified. To obtain two completely homogeneous study groups, propensity score matching was used. The paired groups were compared by descriptive and univariate analyses. Then, logistic regression was used to verify the effects of on- and off-pump CABG on 30-day mortality. Results: None of the baseline characteristics showed significant difference between the groups (P>0.05). None of the analyzed morbidity outcomes showed any difference between the groups, including acute myocardial infarction (3.0% vs. 1.5%; P=0.192), stroke (2.4% vs. 4.2%; P=0.193), and major reoperation (0.6% vs. 0.3%; P=1.000), as well as the major adverse cardiovascular and cerebrovascular events composite outcome (6.3% vs. 7.5%; P=0.541). Mortality also did not differ (1.5% vs. 2.4%; P=0.401), and CPB support was not an independent predictor of risk for 30-day mortality (odds ratio: 2.052; 95% confidence interval: 0,609-6.913; P=0.246). Conclusion: After matching by propensity analyses, similar rates of on- and off-pump 30-day mortality and other major outcomes were observed. In addition, the use of CPB support was not an independent predictor of risk for the occurrence of 30-day mortality.
