Resumen Introducción: La insuficiencia cardiaca en pacientes con fibrilación auricular no valvular (FANV) es de dos a tres veces más frecuente que en individuos sin FANV. Objetivo: Identificar los factores de riesgo cardiometabólico (FRCM) y el tratamiento antitrombótico de pacientes con FANV e insuficiencia cardiaca con fracción de expulsión reducida (IC-FEr), y determinar si existen diferencias conforme al sexo. Métodos: En forma global y de acuerdo con el sexo se analizaron FRCM, riesgo protrombótico, riesgo de sangrado y terapia antitrombótica. Resultados: De 1423 pacientes con FANV, 336 tuvieron IC-FEr. Las mujeres promediaron mayor edad que los hombres. No hubo diferencia entre los sexos respecto al tipo de FANV o uso de anticoagulantes orales directos. La hipertensión arterial sistémica fue más frecuente en mujeres. Un 3.6 % de los pacientes reportó antecedente de ataque isquémico transitorio y 10 % de evento vascular cerebral, sin diferencias en cuanto al sexo. El porcentaje de hombres con riesgo embólico elevado fue mayor, pero sin tratamiento antitrombótico, en comparación con las mujeres. Conclusiones: Se encontraron diferencias significativas de acuerdo con el sexo en pacientes con FANV e IC-FEr, tanto en FRCM y algunas comorbilidades, como en el tratamiento antitrombótico de acuerdo con el riesgo embólico y de sangrado.

Abstract Introduction: Heart failure in patients with non-valvular atrial fibrillation (NVAF) is two to three times more common than in individuals without NVAF. Objective: To identify cardiometabolic risk factors (CMRF) and antithrombotic treatment in patients with NVAF and heart failure with reduced ejection fraction (HFrEF), and to determine if there were differences according to gender. Methods: CMRF, pro-thrombotic risk, bleeding risk, and antithrombotic therapy were globally analyzed and according to gender. Results: Out of 1,423 patients with NVAF, 336 had HFrEF. On average, females were older than males. There was no difference between genders with regard to the type of NVAF or direct oral anticoagulants use. Hypertension was more common in women. History of transient ischemic attack was reported in 3.6% of the patients and cerebrovascular event in 10%, without differences in terms of gender. The percentage of men with elevated embolic risk was higher, but without antithrombotic treatment, in comparison with women. Conclusions: Significant differences were found according to gender in patients with NVAF and HFrEF, both in CMRF and some comorbidities, as well as in antithrombotic treatment according to embolic and bleeding risk.

Objetivo Neiva es considerada endémica para fiebre dengue y fiebre dengue hemorrágico en Colombia. Durante el 2004 se presentó un brote epidémico, siendo necesario caracterizar el comportamiento epidemiológico y clínico durante esta epidemia. Materiales y Métodos Estudio retrospectivo descriptivo de niños menores de 13 años que ingresaron al Hospital Universitario en este periodo, con criterios de Fiebre dengue y Fiebre dengue hemorrágico según la OMS. Se registraron los datos demográficos, clínicos y paraclínicos de ingreso. El análisis fue descriptivo y bivariado exploratorio utilizando la prueba de chi². Resultados De 105 niños el 87,6 % ingresó con diagnóstico de fiebre dengue hemorrágico y el 12,4 % con fiebre dengue. Un 67 % correspondió a menores de 5 años, con mayor frecuencia y severidad en niñas. El 83 % ingresó en los primeros seis días de enfermedad. Hubo datos de choque en el 20 % de los pacientes, de estos el 76 % presentó complicaciones (chi² 29.53, gl 6, p=0.0000). Entre los datos paraclínicos, las aminotransferasas se encontraron 3 a 5 veces el valor normal y hubo correlación entre recuento plaquetario inferior a 20 000 por mm³ y choque al ingreso (chi² 20,65, gl 4, p= 0.0004). La evolución fue favorable; sin embargo, hubo complicaciones en el 32 % de los casos (13 % miocarditis, 19 % hepatitis o encefalitis y 2 % sepsis). Conclusión Las características epidemiológicas y clínicas observadas en esta cohorte de pacientes mostraron una variación en género, edad y órgano blanco, con una incidencia alta de compromiso miocárdico.

Objective Neiva (a southern Colombia city) is endemic for dengue fever and dengue haemorrhagic fever. Neiva has suffered outbreaks of dengue, that in 2004 being the latest one. This study was designed to characterise epidemiological and clinical data from that outbreak of dengue. Material and Methods This was a descriptive, retrospective study of children aged less than 13 years who were admitted to the University Hospital and fulfilled the WHO's clinical and laboratory criteria for dengue or dengue haemorrhagic fever. Demographic, clinical and paraclinical data were recorded and analysed using Chi square (chi²) bivariate tabular test. Results 105 children were diagnosed as suffering from either dengue haemorrhagic fever (87.6%) or dengue fever (12.4%); 67% of them were aged less than 5 years. Girls were more frequently affected by severe clinical manifestations. 83% of the children were admitted during the first six days of the disease; dengue shock syndrome was diagnosed in 20% and 76% presented clinical complications (chi² 29.53, gl 6, p=0.0000). Aminotransferases were 3 to 5 times above normal levels. There was a statistical correlation between low platelet count (less than 20 000 per mm³) and shock during admission (chi² 20.65, gl 4, p=0.0004). Complications arose during clinical evolution in 32% of the cases (13% myocarditis, 19% hepatitis or encephalitis and 2% sepsis). Conclusion The clinical and epidemiological characteristics observed in this cohort evidenced differences in age, gender and organs affected compared to data described in the literature; there was a high incidence of myocarditis.

From August 1997 to August 1998, 334 specimens of Triatoma longipennis and 62 of T. picturata were collected in four groups of localities placed in the zone from Guadalajara, Jalisco to Tepic, Nayarit, in the West Coast of Mexico. Most T. longipennis were collected outdoors (69.2%) while most T. picturata (58.1%) were collected indoors. All collected specimens were examined for Trypanosoma cruzi infection, which was detected on 98 (29.3%) T. longipennis and 17 (27.4%) T. picturata. This study confirms the role of T. longipennis and T. picturata as some of the main T. cruzi vectors to humans in Mexico. Habitation Infestation Rate with T. longipennis was of 0.09 and with T. picturata was of 0.03 and the predominating ecotopes were pile of blocks, chicken coops, pigsties, wall crawls and beds.
