En los últimos años se ha incrementado la inmigración de ciudadanos venezolanos a la República de Colombia1.
Aunque algunas investigaciones han mostrado una diferencia en la presentación de ...condiciones médicas en estos
individuos, aún no existen estudios que evalúen la epidemiología del trauma en esta población2,3. El objetivo del
presente estudio fue comparar las características del trauma en población nacional versus la inmigrante venezolana
haciendo uso del Registro Institucional de Trauma del Hospital Universitario de Santander (RITHUS) en su primer
año de implementación
BackgroundChronic Chagas Cardiomyopathy (CCM) is a unique form of cardiomyopathy compared to other etiologies of heart failure. In CCM, risk prediction based on biomarkers has not been well-studied. ...We assessed the prognostic value of a biomarker panel to predict a composite outcome (CO), including the need for heart transplantation, use of left ventricular assist devices, and mortality.MethodsProspective cohort study of 100 adults with different stages of CCM. Serum concentrations of amino-terminal pro-B type natriuretic peptide (NT-proBNP), galectin-3 (Gal-3), neutrophil gelatinase-associated lipocalin (NGAL), high sensitivity troponin T (hs-cTnT), soluble (sST2), and cystatin-C (Cys-c) were measured. Survival analyses were performed using Cox proportional hazard models.ResultsDuring a median follow-up of 52 months, the mortality rate was 20%, while the CO was observed in 25% of the patients. Four biomarkers (NT-proBNP, hs-cTnT, sST2, and Cys-C) were associated with the CO; concentrations of NT-proBNP and hs-cTnT were associated with the highest AUC (85.1 and 85.8, respectively). Combining these two biomarkers above their selected cut-off values significantly increased risk for the CO (HR 3.18; 95%CI 1.31-7.79). No events were reported in the patients in whom the two biomarkers were under the cut-off values, and when both levels were above cut-off values, the CO was observed in 60.71%.ConclusionThe combination of NT-proBNP and hs-TnT above their selected cut-off values is associated with a 3-fold increase in the risk of the composite outcome among CCM patients. The use of cardiac biomarkers may improve prognostic evaluation of patients with CCM.
Introducción: La escala Zung para depresión ha sido previamente utilizada en pacientes con falla cardíaca; sin embargo, en nuestro conocimiento no se encuentra evidencia de su validez para la versión ...en español y su uso en población adulta con falla cardíaca en Colombia. Objetivo: Determinar la validez de constructo de la escala Zung para depresión en su versión original y proponer una versión abreviada para pacientes adultos con falla cardíaca.
Materiales y Métodos: Estudio de corte transversal, realizado en 200 pacientes de una clínica de falla y trasplante cardiaco, en quienes se aplicó Zung Self-Rating Depression Scale. Se evaluó la consistencia interna por medio del alfa de Cronbach y el análisis factorial fue utilizado para identificar las dimensiones del instrumento.
Resultados: La consistencia interna de la versión original de la escala (20 ítems) fue de α=0.811. El análisis de factores mostró una estructura compuesta por tres factores que explican el 51.59% de la varianza total. La nueva versión abreviada (13 ítems) obtuvo un α=0.819 y los ítems correlacionaron con un único factor que explicó el 33.54% de la varianza total.
Discusión: Nuestros hallazgos son similares a los encontrados por otros autores en diferentes poblaciones a la estudiada.
Conclusiones: Se evidenció validez de constructo tanto para la escala Zung para depresión en su versión original como para la abreviada creada en la población estudiada. Sin embargo, se requieren estudios adicionales que verifiquen estos hallazgos en una muestra representativa y que otros aspectos de la psicometría sean evaluados.
Heart transplant (HT) remains the most frequently indicated therapy for patients with end-stage heart failure that improves prognosis in Chagas cardiomyopathy (CCM). However, the lack of benznidazole ...therapy and availability of RT-PCR follow-up in many centers is a major limitation to perform this life-saving intervention, as there are concerns related with the risk of reactivation. We aimed to describe the outcomes of a cohort of patients with CCM that underwent HT using a conventional protocol with mycophenolate mofetil, without benznidazole prophylaxis or RT-PCR follow-up. Retrospective cohort study. Between 2008-2018, forty-three patients with CCM underwent HT. A descriptive analysis to characterize outcomes as rejection, infectious and neoplastic complications and a survival analysis were carried out. Median of follow-up was 4.3 (IR 4.28) years. Survival at one month, one year, and five years was 95%, 85% and 75%, respectively, infections being the main cause of death (60%). Reactivations occurred in only three patients (7.34%) and were not related to mortality. This cohort showed a favorable survival and a low reactivation rate without an impact on mortality. Our results suggest that performing HT in patients with CCM following conventional guidelines and recommendations for other etiologies is a safe approach.
Chronic Chagas cardiomyopathy (CCM) represents a relevant origin of Heart Failure (HF) in countries where the disease is endemic. CCM exhibits distinct myocardial involvement and is associated with a ...poorer prognosis compared to different HF etiologies. The aim is to explain the features and prognosis of individuals with HF resultant to CCM registered in the Colombian Registry of Heart Failure (RECOLFACA). RECOLFACA registry enrolled 2528 adult patients with HF. A comparison was made between patients diagnosed with CCM and those diagnosed with other etiologies of HF. 88 patients (3.5%) present CCM diagnosis. The individuals diagnosed with both HF and CCM were notably younger in age, had less comorbidities, poorer functional class, and significantly inferior ejection fraction. Finally, the presence of CCM diagnosis was linked to a substantially elevated mortality risk throughout the follow-up period (HR 2.01;95% CI 1.01-4.00) according to a multivariate model adjusted. CCM represents an important etiology of HF in Colombia, drawing attention to a distinct clinical profile and a higher risk of mortality compared to other HF etiologies.
