Histidine-tryptophan-ketoglutarate solution versus blood cardioplegia in cardiac surgery: A propensity-score matched analysis

Background: Choosing a cardioplegic solution is a significant issue in modern cardiac surgery. Although different options are available, the optimal strategy for myocardial protection has not been established. The aim of this study was to compare intraoperative and postoperative effects of histidine–tryptophan–ketoglutarate (HTK) solution with those of standard blood cardioplegia with St Thomas No 2 solution. The study was conducted using a large cohort of adult patients undergoing complex cardiac surgery. Methods: This study was a single center retrospective review of prospectively collected data. Between January 2008 and December 2015, 4480 patients underwent cardiac surgery using cardiopulmonary bypass (CPB) and cardioplegic arrest. Patients were divided into a blood cardioplegia group (n = 3852) and an HTK solution group (n = 628). Propensity score matching was used to adjust for differences between the two groups, and 292 matched pairs were identified. The primary end point was Intensive Care Unit (ICU) length of stay (LOS). Secondary end points included intraoperative changes in serum sodium concentration, readmission to ICU, transfusion of blood products, 30-day hospital readmission, 30-day mortality, and the incidence of major postoperative complications. Results: No significant differences were found between the matched groups with regard to baseline characteristics. Aortic cross-clamp and CPB times were longer for the blood cardioplegia (147.4 versus 132.8 min; P less than .001). Administration of HTK solution was associated with acute and transient hyponatremia (141 versus 130 mmol/L; P less than .001). ICU LOS was comparable between the groups (5.4 versus 5.4 days; P = .585). No significant differences were noted in any other secondary end point. Conclusions: During complex cardiac surgery, both cardioplegia techniques were equivalent in terms of early clinical outcomes. © 2018 Forum Multimedia Publishing, LLC

Risk factors for cardiovascular and chronic diseases in a coffee-growing population

Objetivos Estimar la prevalencia de los factores de riesgo cardiovascular y de enfermedades crónicas en población caficultora colombiana. Métodos Estudio transversal, entre febrero y noviembre de 2007. Muestreo multietápico y por conglomerados, 55 veredas de 13 municipios, 2 516 encuestas. Cuestionarios recomendados por OPS, mediciones antropométricas y bioquímicas. Análisis descriptivos univariados y bivariados, IC95%, pruebas de significan-cia, comparación con estudios previos. Resultados La prevalencia de fumadores actuales fue 21,1 % (IC95%: 19,2-23,3), sedentarismo 31,2 % (IC95%: 27,8-32,6), personas que consumen al día menos de 5 porciones entre frutas y verduras 86,3 % (IC95%: 84,4-87,9), consumo eleva-do de alcohol 2,2 % (IC95%: 1,6-3,2), hipertensión arterial 26,2 % (IC95%: 23,9-28,6), diabetes 4,6 % (IC95%: 3,6-5,8), hiperlipidemia 62,1 % (IC95%: 59,5-64,7), sobrepeso y obesidad 42,9 % (IC95%: 40,4-45,5). El 85 % tenían al menos 2 o más factores de riesgo simultáneamente. Sedentarismo, diabetes, hiperlipidemia y sobrepeso/obesidad fue mayor en mujeres (p<0,001). Consumo de alcohol y taba-quismo fue mayor en hombres (p<0,001). Edad, estado civil, educación, ingresos y sistema de salud estuvieron relacionados con los factores de riesgo estudiados. Conclusiones Se aportan nuevos conocimientos a la escasa información disponi-ble en poblaciones rurales latinoamericanas. En comparación con el segundo es-tudio nacional de factores de riesgo de enfermedades crónicas (ENFREC II) no se encontraron avances importantes en disminución de la prevalencia de factores de riesgo. Se requieren estudios adicionales para profundizar en los determinantes sociales y de los sistemas de salud, que expliquen los hallazgos de este estudio.Q3390-403Objectives Estimating the prevalence of cardiovascular and chronic disease risk factors in a Colombian coffee-growing population. Methods This cross-sectional study was carried out from February to November 2007. Multistage conglomerate sampling of 55 rural areas in 13 municipalities led to 516 people being surveyed. The questionnaires used were recommended by PAHO (anthropometric and biochemical measurements). The resulting data was subjected to univariate and bivariate descriptive analysis using 95 % CI, significan-ce tests and comparison with previous studies. Results There was 21.1 % (19.2-23.3 95 %CI) current smoker prevalence, 31.2 % sedentarism (27.8-32.6 95 % CI), 86.3 % people consumed less than 5 portions of fruit and vegetables per day (84.4-87.9 95 % CI), 2.2 % had high alcohol con-sumption level (1.6-3.2 95 %CI), 26.2 % suffered from hypertension (23.9-28.6 95 % CI), 4.6 % diabetes (3.6-5.8 95 % CI), 62.1 % hyperlipidaemia (59.5-64.7 95 % CI) and 42.9 % (40.4-45.5 95 % CI) were overweight or obese. 85 % had at least 2 or more risk factors simultaneously. Sedentarism, diabetes, hyperlipidaemia and being overweight /obese was greater in females (p<0.001). Alcohol consumption and smoking were greater in males (p<0.001). Age, civil state, education, income and health system were related to the risk factors being studied. Conclusions The study provided fresh knowledge concerning the lack of available information regarding rural Latin-American populations. Compared to the second Colombian study of chronic disease risk factors (ENFREC II), no important ad-vances were found regarding a reduction of the prevalence of risk factors. Further studies are required for going deeper into social determinants and health systems explaining this study’s findings

Inflammaging as a link between autoimmunity and cardiovascular disease: The case of rheumatoid arthritis

Currently, traditional and non-traditional risk factors for cardiovascular disease have been established. The first group includes age, which constitutes one of the most important factors in the development of chronic diseases. The second group includes inflammation, the pathophysiology of which contributes to an accelerated process of vascular remodelling and atherogenesis in autoimmune diseases. Indeed, the term inflammaging has been used to refer to the inflammatory origin of ageing, explicitly due to the chronic inflammatory process associated with age (in healthy individuals). Taking this into account, it can be inferred that people with autoimmune diseases are likely to have an early acceleration of vascular ageing (vascular stiffness) as evidenced in the alteration of non-invasive cardiovascular tests such as pulse wave velocity. Thus, an association is created between autoimmunity and high morbidity and mortality rates caused by cardiovascular disease in this population group. The beneficial impact of the treatments for rheumatoid arthritis at the cardiovascular level has been reported, opening new opportunities for pharmacotherapy

Data sharing: A new editorial initiative of the international committee of medical journal editors. Implications for the editors´ network

The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship -emphasizing the importance of responsibility and accountability-, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors´ Network of the European Society of Cardiolog

Authorship: From credit to accountability. Reflections from the Editors´ Network

The Editors´ Network of the European Society of Cardiology (ESC) provides a dynamic forum for editorial discussions and endorses the recommendations of the International Committee of Medical Journal Editors (ICMJE) to improve the scientific quality of biomedical journals. Authorship confers credit and important academic rewards. Recently, however, the ICMJE emphasised that authorship also requires responsibility and accountability. These issues are now covered by the new (fourth) criterion for authorship. Authors should agree to be accountable and ensure that questions regarding the accuracy and integrity of the entire work will be appropriately addressed. This review discusses the implications of this paradigm shift on authorship requirements with the aim of increasing awareness on good scientific and editorial practices
