Background
Breast milk is the optimal food for humans, however, many mothers face challenges in sustaining exclusive breastfeeding (EBF). Prenatal education (PE) has been suggested as a strategy to promote EBF, but there is evidence that its impact on EBF duration remains inconclusive. This study aimed to evaluate the effect of PE on EBF continuati...
Although the greatest delays in cancer diagnosis in Latin America occur in the provider interval little is known about the related factors. This study aims to analyze factors influencing access to cancer diagnosis -from initial contact with health services to confirmation- from institutional stakeholders' perspective in public healthcare networks o...

Background
During the 1990s, global eating habits changed, affecting poorer and middle-income nations, as well as richer countries. This shift, known as the "obesity transition," led to more people becoming overweight or obese worldwide.

Introducción: La mortalidad neonatal es un indicador en salud pública. En Ecuador la tasa defunción neonatal es 6 por cada 1 000 nacidos vivos. El objetivo del presente estudio fue identificar los principales determinantes de mortalidad neonatal en los neonatos fallecidos entre los años 2014 a 2017 en el Ecuador.
Metodología: Es presente estudio e...
Background: In Ecuador, the neonatal mortality rate has increased from 4.1 to 6.0 per 1000 live births between 2014 and 2019. We aimed to develop and validate a health risk assessment tool for predicting neonatal mortality and to reach a nationwide consensus on stratified management. Methods: We retrospectively analyzed all neonatal deaths register...

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. Setting: Ecuadorian neonates who died at ≤28 days of...
We are currently experiencing the first global pandemic in the digital age due to the COVID-19 disease, caused by the SARS-CoV-2 virus. As we try to protect ourselves with isolation and social distancing measures, the digital tools for connecting with the world become more critical. Newborn health care, a critical public health problem everywhere,...
Introduction
There is evidence that demonstrates lower incidence rates of cardiometabolic factors at the highlands. There are no studies which correlate the altitude with formally calculated cardiovascular risk by a meter-by-meter approach. Under the hypothesis that cardiovascular risk is inversely associated with altitude, this study was aimed to...

Congenital adrenal hyperplasia (CAH) is a group of rare orphan disorders caused by mutations in seven different enzymes that impair cortisol biosynthesis. The 17α-hydroxylase deficiency (17OHD) is one of the less common forms of CAH, corresponding to approximately 1% of the cases, with an estimated annual incidence of 1 in 50,000 newborns. Cases de...
Introduction: Integrated care (IC) has potential to improve health care experience and treatment adherence by properly coordinated and stratified care. We aimed to: (i) assess the patients’ perception about the degree of integrality in their care, (ii) identify potential predictors for risk assessment; and, (iii) assess clinicians’ and patients’ ex...
Background:
Early cognitive intervention is the only routine therapeutic approach used for amelioration of intellectual deficits in individuals with Down's syndrome, but its effects are limited. We hypothesised that administration of a green tea extract containing epigallocatechin-3-gallate (EGCG) would improve the effects of non-pharmacological c...

Acting to address the amount of physical activity of patients with chronic obstructive pulmonary disease (COPD) is recommended as part of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommendations [1]. A level lower than approximately 5000 steps for day (sedentary lifestyle index) is associated with significantly increased he...
Introduction: Up to 80% of deaths related to chronic diseases (CDs) occur in low-middle income countries. Ecuadorian social security implemented a new policy for improving health care to chronic patients by two main strategies: (i) by adopting the frame of the renewed primary health care of the World Health Organization; and (ii) by massive contrac...

The recent prospect of pharmaceutical interventions for cognitive impairment of Down syndrome (DS) has boosted a number of clinical trials in this population. However, running the trials has raised some methodological challenges and questioned the prevailing methodology used to evaluate cognitive functioning of DS individuals. This is usually achie...
Background: Predictive risk modeling elaborated from large population-based datasets using citizens traits, including historical information on use of healthcare resources, as potential predictors have shown to be useful mainly for two purposes: (i) to design health policies, with a preventive approach, in a given geographical area; and, (ii) to id...
