RESUMO
Depressive disorders are a leading cause of disability and are globally pervasive. It is estimated that 80% of depression occurs in low-income and middle-income countries. Depression is associated with worse outcomes in patients with cardiac disease including heart failure (HF); however, mechanistic understanding to explain heightened risk in HF remains poorly characterized. We examined the association between depressive symptoms and cardiac structure and function by transthoracic echocardiography. We selected a random sample of adult participants in Puno and Pampas de San Juan de Miraflores, Peru, from the CRONICAS cohort study. Depression symptoms were self-reported and measured with the Center for Epidemiological Studies Depression Scale in 2010. Participants underwent transthoracic echocardiography in 2014. Multivariable linear regression was used to examine the relationship between depressive symptoms and echocardiographic measures of cardiac structure and function and was adjusted for relevant covariates. Three hundred and seventy-three participants (mean age 56.7 years, 57% female) were included in this analysis of which 91 participants (24%) had clinically significant depressive symptoms. After adjustment, clinically significant depressive symptoms were associated with a reduced diastolic relaxation velocity compared to non-depressed subjects (-0.72 cm/s, 95% CI -1.21 to -0.24, p = 0.004). Other differences between depressed and non- depressed participants were less obvious. In conclusion, clinically significant depressive symptoms were associated with a lower septal e' velocity in the Peruvian population. Depressive symptoms were not obviously associated with other abnormalities in cardiac structure or function.

The COVID-19 pandemic may indirectly impact hospitalizations for other natural causes. Belo Horizonte is a city with 2.5 million inhabitants in Brazil, one of the most hardly-hit countries by the pandemic, where local authorities monitored hospitalizations daily to guide regulatory measures. In an ecological, time-series study, we investigated how the pandemic impacted the number and severity of public hospitalizations by other natural causes in the city, during 2020. We assessed the number and proportion of intensive care unit (ICU) admissions and in-hospital deaths for all-natural causes, COVID-19, non-COVID-19 natural causes, and four disease groups: infectious, respiratory, cardiovascular, and neoplasms. Observed data from epidemiological week (EW) 9 (first diagnosis of COVID-19) to EW 48, 2020, was compared to the mean for the same EW of 2015-2019 and differences were tested by Wilcoxon rank-sum test. The five-week moving averages of the studied variables in 2020 were compared to that of 2015-2019 to describe the influence of regulatory measures on the indicators. During the studied period, there was 54,722 hospitalizations by non-COVID-19 natural causes, representing a 28% decline compared to the previous five years (p<0.001). There was a concurrent significant increase in the proportion of ICU admissions and deaths. The greater reductions were simultaneous to the first social distancing decree or occurred in the peak of COVID-19 hospitalizations, suggesting different drivers. Hospitalizations by specific causes decreased significantly, with greater increase in ICU admissions and deaths for infectious, cardiovascular, and respiratory diseases than for neoplasms. While the first reduction may have resulted from avoidance of contact with healthcare facilities, the second reduction may represent competing causes for hospital beds with COVID-19 after reopening of activities. Health policies must include protocols to address hospitalizations by other causes during this or future pandemics, and a plan to face the rebound effect for elective deferred procedures.
