Personal safety during the COVID-19 pandemic: realities and perspectives of healthcare workers in Latin America

Healthcare workers exposed to coronavirus (COVID-19) may not have adequate access to personal protective equipment (PPE), safety procedures, and diagnostic protocols. Our objective was to evaluate the reality and perceptions about personal safety among healthcare workers in Latin America. This is a cross-sectional, online survey-based study administered to 936 healthcare professionals in Latin America from 31 March 2020 to 4 April 2020. A 12-item structured questionnaire was developed. A total of 936 healthcare workers completed the online survey. Of them, 899 (95.1%) were physicians, 28 (2.9%) were nurses, and 18 (1.9%) were allied health professionals. Access to protective equipment was as follows: gel hand sanitizer (n = 889;95%), disposable gloves (n = 853;91.1%), disposable gowns (n = 630;67.3%), disposable surgical masks (785;83.9%), N95 masks (n = 516;56.1%), and facial protective shields (n = 305;32.6%). The vast majority (n = 707;75.5%) had access to personal safety policies and procedures, and 699 (74.7%) participants had access to diagnostic algorithms. On a 1-to-10 Likert scale, the participants expressed limited human resources support (4.92 +or- 0.2;mean +or- SD), physical integrity protection in the workplace (5.5 +or- 0.1;mean +or- SD), and support from public health authorities (5.01 +or- 0.12;mean +or- SD). Healthcare workers in Latin America had limited access to essential PPE and support from healthcare authorities during the COVID-19 pandemic.

Cardiovascular admissions in intensive care units during COVID-19 pandemic

The COVID-19 pandemic has led to measures of social isolation, labor restrictions, a strong information campaign and the suspension of scheduled medical activities. The aim of this study was to describe the impact of these measures on the number of hospitalizations in Cardiovascular Intensive Care Units, with the hypothesis that the social behavior generated by this emergency promotes a decreased demand for medical care, even when severe cardiovascular disease is involved. We compared the number of admissions in March-April 2010-2019 versus March-April 2020, based on a prospective study including six institutions (three public and three private) that use Epi-CardioR as a multicenter registry of cardiovascular care unit discharge. Altogether, we included 6839 patients discharged during the 11-year study period (2010-2020). The average number of patient admissions on March-April 2010-19 was 595 (CI 95%: 507-683) and decreased to 348 in 2020 fall of 46.8%, p.

Hydroxychloroquine. Cardiology's viewpoint in times of coronavirus pandemic

Due to the coronavirus disease 2019 (COVID-19) pandemic, a wide number of compounds are under scrutiny regarding their antiviral activity, one of them being hydroxychloroquine. Cardiac aspects of the use of chloroquine and hydroxychloroquine are reviewed in this manuscript. A non-systematic review of the medical literature was performed. Information about their safety and efficacy as antimalarials, antivirals, as well as in the long-term treatment of rheumatic diseases was collected. We found an anti-inflammatory effect with reduction of long-term cardiovascular events, a very infrequent heart disease due to a lysosomal effect of the drug, and at the hemodynamic level hypotension, tachycardia, and QT interval prolongation, exacerbated when combined with azithromycin. However, the rate of adverse cardiac events of hydroxychloroquine (and chloroquine) was low.
