Fallo en la regulación de la fertilidad posparto en mujeres en vulnerabilidad social en Colombia / Failured to regulate postpartum fertility in vulnerable women in Colombia

Objetivo: Evaluar la prevalencia de fallo en la regulación de la fertilidad posparto y la asociación con otros factores en un municipio colombiano (2017). Método: Estudio observacional de corte transversal con 148 mujeres. Se aplicó un muestreo no aleatorio para incluir mujeres que hubieran tenido un parto en los últimos 5 años. Se calcularon la prevalencia y las razones de prevalencia. Se exploró la asociación con la prueba χ2 o la prueba exacta de Fisher bajo una significancia estadística de 0,05. Resultados: Se encontró una prevalencia de fallo de la regulación de la fertilidad posparto del 40,5%. La prevalencia se asoció con ejercer oficios del hogar, tener uno o dos hijos, no planificar o no acceder a métodos de planificación y haber tenido un embarazo con periodo intergenésico menor de 2 años (p < 0,05). Conclusiones: Es necesario implementar estrategias para identificar barreras de acceso a la planificación, impactando en el espaciamiento entre embarazos y el acceso a los servicios. Lo anterior para generar múltiples beneficios para la madre, su hijo/a, el sistema de salud y la sociedad.

Objective: To evaluate the prevalence of regulated postpartum fertility failure and possible associated factors in a Colombian municipality (2017). Method: Cross-sectional observational study of 148 women. A non-random sampling method was used to include women who had given birth to a child in the last five years. Prevalence and prevalence ratios were calculated. Associations were examined at 0.05 statistical significance using χ2 test or Fishers exact test. Results: The prevalence of postpartum fertility failure was found to be 40.5%. The prevalence was associated with household work, having one or two children, not planning, or not having access to planning methods, and having a pregnancy with an interval between pregnancies of less than 2 years (p < 0.05). Conclusions: It is necessary to implement strategies to identify barriers to access to planning, which have an impact on the spacing between pregnancies and access to services. This will have multiple benefits for mother, child, health system and society.

Immune system gene polymorphisms associated with severe dengue in Latin America: a systematic review

ABSTRACT One of the main challenges in the clinical management of dengue is the early identification of cases that could progress to severe forms of the disease. A biomarker that may enable this identification is the presence of genetic polymorphisms in genes associated with immune responses. The objective of this study was to perform a systematic review of the Latin American literature on these genes. An electronic literature search was carried out in PubMed, Scopus, Lilacs, and the Virtual Health Library, and reference lists of systematic reviews in the area. Case-control studies conducted in Latin American countries examining at least one form of genetic polymorphism related to immune responses against severe dengue were included. In total, 424 articles were identified and 26 were included in this systematic review. Of the 26 selected articles, 16 reported polymorphisms associated with the risk of developing severe dengue (Risk); Similarly, 16 articles reported polymorphisms associated with a decreased risk of severe dengue (Protective). The final analysis revealed that multiple polymorphisms in immune system genes were early markers of the progression of dengue in Latin Americans and found that polymorphisms of the TNF-alpha gene may have a critical role in dengue pathogenesis.

Linfangiectasia intestinal: Reporte de un caso / A case report of Intestinal Lymphangiectasia

A propósito del caso de un paciente de 7 meses de vida remitido desde Yopal a la ciudad de Bogotá, se revisa el tema de la linfagiectasia intestinal. Esta es una rara enfermedad que involucra los vasos linfáticos intestinales, y origina hipoproteinemia, edemas, ascitis y enteropatía perdedora de proteínas.

This is the case report of a 7 month old child from Yopal with intestinal lymphangiectasia who was sent to Bogota. We also review the issue of intestinal lymphangiectasia, a rare disease involving intestinal lymphatic vessels which caused hypoproteinemia, edema, ascites and protein-losing enteropathy.
