[Cardiac Tamponade due to Rupture of a Giant Coronary Aneurysm over Coronary Fistulas: Report of an Unusual Case]

Coronary artery fistulas are rare clinical entities and their association with giant coronary aneurysms is even more unusual. Most fistulas are asymptomatic, but aneurysms could develop symptoms depending on their diameter. We present a patient with chest pain and cardiac arrest, who later developed cardiac tamponade that needed emergency surgery, due to rupture of a giant coronary aneurysm developed from confluent coronary artery fistulas from two coronary arteries to pulmonary artery.

[Association between the risk of major depression and low physical activity in peruvian workers studying in universities]

In order to assess if an association exists between the risk of major depression (RMD) and physical activity (PA), controlling for demographic and academic variables in workers enrolled in undergraduate studies at a private university in Lima, Peru, we carried out a cross-sectional study of 1,111 people. We used the Major Depression Inventory (MDI) and the International Physical Activity Questionnaire (IPAQ) to measure RMD and PA, respectively. RMD prevalence was 4.2%. In the multiple regression model adjusted for age, gender, unemployment and hours of sleep, low levels of PA were associated with increased odds of RDM (OR: 2.15, 95% CI: 1.16 to 4.00). We conclude that there is an association between RMD and PA in the study population, independent of demographic and academics factors. Strategies to improve screening and development of longitudinal studies to assess causality are suggested.
