Findings on Sputnik V Vaccine Against COVID-19

The Sputnik V vaccine was developed by Gamaleya NRCEM. Similarly to the Oxford-AstraZeneca vaccine, it is based on a viral vector, and its findings were published in Lancet. The Russian vaccine comprises two different adenoviruses in the first and the second dose, making it more effective and generating an extended immune response. Both vectors carry

Safety and Efficacy of the Pfizer-BioNTech Vaccine Against COVID-19

The NEJM has published the efficacy of the COVID-19 vaccine developed by Pfizer and BioNTech, featuring slight differences in the age of enrollment and endpoint definitions compared with other vaccines. Similarly to Moderna‘s, this vaccine is composed of a lipid nanoparticle with modified RNA that encodes a spike glycoprotein covering the surface, modified by two

Efficacy of AstraZeneca’s Vaccine against COVID-19

This study, published in the Lancet, looks into the vaccine resulting from the collaboration of the Oxford University and AstraZeneca, among others. Data include interim results from 4 ongoing blind randomized controlled studies currently carried out in the UK, Brazil and South Africa.  All participants over 18 years of age were assigned 1:1 to the

N95 and Surgical Face Mask Sterilization Is Feasible

This study shows re-sterilization of N95 and KN95 surgical face masks is indeed feasible, though not all techniques will render the same results and not all protection elements will keep filtration capacity.  COVID-19 has produced, among other things, a shortage of healthcare protection gear.  The CDC has suggested reusing face masks to overcome this shortage.

Convalescent Plasma for Severe Pneumonia from COVID-19

After testing multiple drugs and drug combinations in COVID-19 patients, only Remdesivir – for hospitalized patients – and dexamethasone – in patients requiring Oxygen – have shown some benefits.  Convalescent plasma has been used for years assuming passive immunization might help control the infection until a specific immune response is established in the infected person.

Natural History of Asymptomatic COVID-19 Infection

Information on the natural history of asymptomatic infection with the new coronavirus (COVID-19) remains scarce. We are just beginning to understand what happens with patients with severe disease. The outbreak of COVID-19 on the cruise ship Diamond Princess provided a unique opportunity to study contacts and patients with asymptomatic infection within a closed population. This

Efficacy of Remdesivir against COVID-19

This final report published in NEJM about the efficacy of remdesivir against COVID-19 infection vs placebo showed its superiority though only in soft end points, which does not seem to modify the course of this pandemic. Multiple drugs initially promising have been shown ineffective against the new virus. The case of hydroxychloroquine resulted paradigmatic: not

Long-Term Cardiovascular Effects of COVID-19

In many places worldwide, the worst part of the pandemic is still to come. Meanwhile, in other areas, the number of cases is rising again. In this context, the long-term effects of COVID-19 are starting to show. Many believe this is not a current issue, but it will definitely be a problem in the future.

LATAM: Information on the Impact of the Pandemic with a Focus on MI

There are several studies from all corners of the world (China, Europe, USA) presenting data on the impact of COVID19 on interventional cardiology in general, and on MI in particular. What is new about this study is that it presents data on LATAM and that it has been published in an international magazine.  Seldom do

Myocardial Injury for COVID-19 Even in Young Patients with Mild Symptoms

Most young COVID-19 patients not requiring hospitalization showed abnormal cardiac magnetic resonance imaging (CMR) beyond two months after diagnosis. Myocardial injury had been found in more serious cases, but not in a healthy population recovered at home. The increasing evidence of the virus’ capacity to directly affect the heart across the whole population and disease
