BackgroundDespite the adoption of campaigns to interrupt the main vector and to detect Trypanosoma cruzi in blood banks, millions of people are still chronically infected; however, the prevalence data are limited, and the epidemiology of Chagas disease has not been systematically evaluated. This study aimed to estimate the prevalence of Chagas disease in Colombia.MethodsA systematic literature review and meta-analysis was conducted to select all observational studies reporting the prevalence of Chagas disease in Colombia, based on serological diagnosis in participants of any age and published between January 2007 and November 2017. Pooled estimates and 95% confidence intervals (95% CIs) were calculated using random-effects models. In addition, the I2 statistic was calculated.ResultsThe literature search yielded a total of 1,510 studies; sixteen articles with relevant prevalence data were included in the systematic review. Of these, only 12 articles were included for entry in the meta-analysis. The pooled prevalence of Chagas disease across studies was 2.0% (95% CI: 1.0–4.0). A high degree of heterogeneity was found among studies (I2 > 75%; p < 0.001). The publication bias was not statistically significant (Egger’s test, p = 0.078). The highest pooled prevalences were found in the adult population (3.0%, 95% CI: 1.0–4.0), pregnant women (3.0%, 95% CI: 3.0–4.0) and the Orinoco region (7.0%, 95% CI: 2.2–12.6).ConclusionsThe results indicate that the T. cruzi-infected population is aging, the adult population, pregnant women and that the Orinoco region (department of Casanare) have the highest prevalences. These results highlight the need to maintain screening and surveillance programs to identify people with chronic T. cruzi infections.

The pharmacological management of adults with chronic-phase Chagas disease is challenging despite it being the recent focus of extensive research. One of the challenges in the current clinical practice guidelines (CPGs) landscape is the existence of nonevidence-based recommendations for the use of laboratory tests in treatment monitoring. This study aimed to systematically assess the quality and consistency of recommendations of CPGs on the pharmacological management of adults with chronicphase Chagas disease. Systematic literature searches were conducted in MEDLINE, EMBASE, SciELO and Google to identify all published CPGs relevant to the pharmacological management of Chagas disease, between January 2010 and March 2016. Three independent reviewers assessed the quality of each CPG using the Appraisal of Guidelines Research and Evaluation (AGREE) II instrument. A total of fi ve CPGs were included and the overall quality of the guidelines for therapeutic drug monitoring of Chagas disease was moderate-to-low. There was considerable variation in the quality of the CPGs across the AGREE II domains. The domains of scope/purpose, stakeholder involvement, and clarity of presentation were rated well, and the domains of applicability and editorial independence received poor ratings. This review showed that the methodological quality of CPGs for Chagas disease was generally inappropriate, and there was no explicit link between the best available evidence and current recommendations.

Introduction:The development of clinical practice guidelines (CPGs) has increased; this study aimed to assess the quality of CPGs for the management of Chagas disease. Methods: Following a systematic search of the scientifi c literature, two reviewers assessed the eligible guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE) II instrument. Results: Five CPGs were included. The AGREE domains of scope/purpose, stakeholder involvement, and clarity of presentation were rated well, and the domains of applicability and editorial independence received poor ratings. Conclusions: The quality of CPGs for Chagas disease is poor, and signifi cant work is required to develop high-quality guidelines.

Chagas disease represents an important cause of heart failure (HF) and affects health-related quality of life (HRQoL). The study aimed to evaluate and compare the HRQoL of patients with chagasic HF and matched non-Chagas controls to identify factors associated with HRQoL. A cross-sectional study with pair-matched controls was conducted in Colombia. From October 2018 to December 2019, a total of 84 HF patients were screened for study subjects. Four were excluded, resulting in 80 patients for the analysis, among whom 40 patients with Chagas were enrolled as cases and 40 gender- and age-matched non-Chagas patients as controls. The Kansas City Cardiomyopathy Questionnaire (KCCQ) and the Minnesota Living with Heart Failure Questionnaire (MLWHFQ) were used to measure HRQoL. Demographic, clinical, and laboratory data were obtained from each subject. Health-related quality of life scores were significantly worse among the Chagas group than among the non-Chagas group in the KCCQ domains of physical functioning and symptoms and in the MLWHFQ scale. In the multivariate analysis, the variables associated with lower HRQoL scores were living alone, obesity, having less than 12 years of education, and an increase in left ventricular diameters in the systole and diastole. Health-related quality of life in patients with chronic HF is impaired across all domains. Chagas patients showed worse HRQoL scores than non-Chagas patients. Six variables, some potentially modifiable, were independently associated with worse HRQoL.

Introducción. A pesar de que en Colombia hay una alta prevalencia de embarazos en adolescentes, aún no se han establecido los resultados obstétricos y perinatales adversos en esta población.Objetivo. Caracterizar los desenlaces obstétricos y perinatales de las gestantes adolescentes atendidas en el Hospital Militar Central de Bogotá D.C., Colombia.Materiales y métodos. Estudio observacional, retrospectivo y transversal realizado mediante la revisión de las historias clínicas de 147 gestantes adolescentes atendidas entre mayo de 2012 y diciembre de 2015 en el Hospital Militar Central de Bogotá D.C.Resultados. El promedio de edad fue 17±1.5 años; 59.8% eran estudiantes (secundaria y educación superior) y 64.6%, solteras. En cuanto a los controles prenatales, 127 (86.4%) los iniciaron tardíamente y 108 (73.5%) tuvieron menos de 4. La frecuencia general de complicaciones obstétricas fue 27.9%, entre las que se destacan los trastornos hipertensivos del embarazo (10.2%) y la amenaza de parto pretérmino (8.2%); no se presentaron muertes maternas. Por su parte, las patologías neonatales más comunes fueron ictericia neonatal (4.8%) y síndrome de dificultad respiratoria (3.4%).Conclusiones. Las complicaciones se presentaron con mayor frecuencia en las adolescentes que iniciaron los controles prenatales de forma tardía, por lo que se deben implementar estrategias para garantizar el inicio temprano de estos controles y la adherencia a los mismos. Además, es necesario evaluar el impacto de los programas de planificación familiar en esta población.

RESUMENLa incidencia de cáncer durante la gestación es de 1: 1000 a 2000 embarazos, siendo los más frecuentes el de cérvix, mama, ovario, melanoma, tiroides, colon y hematológicos como linfoma y leucemia. A pesar de ser una entidad poco frecuente en el embarazo, se ha visto una tendencia a aumentar en los últimos años debido al incremento progresivo de la edad materna en el momento de la concepción.El carcinoma gástrico es una patología aún menos frecuente, siendo su incidencia durante la gestación de aproximadamente 0.016% a 0.026% en las series de casos de Japón, país con la mayor prevalencia de enfermedad. La cirugía es el tratamiento oncológico menos controversial durante la gestación. En los últimos años, ha cobrado importancia la quimioterapia adyuvante con antineoplásicos de tipo antimetabolito como el 5 fluoracilo (5 -FU), medicamento que ha demostrado mejoría de la supervivencia en pacientes gestantes con adenocarcinoma gástrico. Desafortunadamente, el 96.7% de los casos son diagnosticados en estadíos avanzados, pues su presentación clínica suele confundirse con las manifestaciones propias de la primera mitad de la gestación como son las nauseas y el vomito.Presentamos dos casos clinicos, el de una gestante de 34 años con embarazo de 19 semanas y 3 días al momento del diagnóstico de un carcinoma gástrico Bormann III, llevada a laparotomía con intención curativa a las 21 semanas con hallazgo intraoperatorio de enfermedad metastásica avanzada y tumor ovárico izquierdo sugestivo de tumor de Krukenberg, a quien se le inicia a las 23 semanas quimioterapia paliativa con esquema FOLFIRI el cual recibió hasta la finalización de la gestación a las 33 semanas por restricción del crecimiento intrauterino y posteriormente durante el puerperio; y el de una gestante de 31 años con embarazo de 26 semanas y 6 días quien se ingresa para estudio de emesis persistente durante la gestación con confirmación diagnóstica de adenocarcinoma gástrico Bormann III asociado a Restricción del crecimiento intrauterino que fue llevada a cesárea a las 34 semanas y en el puerperio a gastrectomía total con vaciamiento ganglionar del area celiaca y reconstrucción en Y de Roux.
