The Role of Exercise-Based Cardiac Rehabilitation After Myocardial Infarction on Cholesterol Transfer to HDL.

High-density lipoprotein (HDL) is associated with decreased incidence of cardiovascular events, and its functionality also influences prognosis. Exercise is an important tool to improve prognosis in the post-infarction (MI) population, but the role of exercise on HDL functionality is poorly understood. Sixty-two patients with acute MI were randomized in a supervised exercise program for 12-14 weeks (exercise group-EG) or a control group (CG).

Factors associated with asthma symptoms in Colombian subpopulations aged 1 to 17 and 18 to 59: Secondary analysis of the study "Prevalence of asthma and other allergic diseases in Colombia 2009-2010".

Background: Asthma, a chronic inflammatory lung disease, is one of the leading causes of disability, demands on health resources, and poor quality of life. It is necessary to identify asthma-related risk factors to reduce the presence and development of symptoms.

Objective: This study aimed to explore the association of multiple possible factors with asthma symptoms in two subpopulations, children, adolescents, and adults, in six cities in Colombia.

Development of a diagnostic multivariable prediction model of a positive SARS-CoV-2 RT-PCR result in healthcare workers with suspected SARS-CoV-2 infection in hospital settings.

Background: Despite declining COVID-19 incidence, healthcare workers (HCWs) still face an elevated risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. We developed a diagnostic multivariate model to predict positive reverse transcription polymerase chain reaction (RT-PCR) results in HCWs with suspected SARS-CoV-2 infection.

Methods: We conducted a cross-sectional study on episodes involving suspected SARS-CoV-2 symptoms or close contact among HCWs in Bogotá, Colombia.

The association between pre-pregnancy and first-trimester hair cortisol and preterm birth: a causal inference model.

Adverse life events and chronic psychological distress before and during pregnancy have frequently been associated with preterm birth but the biological underpinnings remain unclear. We investigated the association between corticosteroid levels in pre-pregnancy and first-trimester hair and the risk of preterm birth. We followed N = 1,807 pregnant women from a prospective pre-birth cohort study in Lima, Perú.
