Is a higher altitude associated with shorter survival among at-risk neonates?

Introduction: We hypothesize that high altitudes could have an adverse effect on neonatal health outcomes, especially among at-risk neonates. The current study aims to assess the association between higher altitudes on survival time among at-risk neonates.

Methods: Retrospective survival analysis.

Morbidity and Mortality Due to Pneumococcal Disease in Children in Ecuador from 2005 to 2015.

Introduction: Studies have shown that pneumococcal disease significantly increases morbidity and mortality rates in children 5 years old and under. These infections constitute the main cause of preventable deaths in the world, considering the availability of vaccination. Considering that Ecuador is in a high incidence region, despite the introduction of the vaccine, this study aims to describe the burden of hospitalized pneumococcal disease and related mortality in our country between 2005 and 2015, to help decision-making processes for the health authorities.
