In a study published in JAMA today, Mount Sinai researchers report findings that shed some light on the disproportionate impact of COVID-19 on Blacks, who have experienced rates of infection and death that are much greater, in some areas twice and three times more, than their proportion of the population. Our study suggests one factor that may
The emergence of adaptive immunity in response to the new Betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), occurs within the first 7 to 10 days of infection. Understanding the key features and the B-cell evolution – and T-cell-mediated adaptive immunity to SARS-CoV-2 is essential to predict the outcomes of coronavirus disease 2019 (COVID-19) and
Mesenchymal stem/stromal cells are not infected by SARS-CoV-2 and retain their immunomodulatory potential as published by Institute for Transfusion Medicine and Immunohaematology, German Red Cross Blood Donor Service in Frankfurt am Main on Stem Cells Report. Previous studies reported safety and applicability of Mesenchymal Stem/Stromal Cells (MSC) to ameliorate pulmonary inflammation in ARDS. Thus, multiple
Researchers at Karolinska Institutet and Science for Life Laboratory in Sweden and Tor Vergata University of Rome in Italy have mapped the immune response in children affected by a rare but life-threatening inflammatory syndrome associated with COVID-19. The study, which is published in the scientific journal Cell, reveals that the inflammatory response differs from that
Multisystem inflammatory syndrome in children (MIS-C), believed to be linked to COVID-19, damages the heart to such an extent that some children will need lifelong monitoring and interventions, said the senior author of a medical literature review. Case studies also show MIS-C can strike seemingly healthy children without warning three or four weeks after asymptomatic
Young adults with underlying conditions such as morbid obesity, diabetes and hypertension are at the highest risk of being placed on a ventilator or dying from COVID-19, according to a study of 3,000 hospitalized patients aged 18 to 34. The analysis, published Wednesday in the journal JAMA Internal Medicine, focused on patients hospitalized between April and
SARS-CoV-2, the virus that causes COVID-19, is entirely new to infectious disease researchers and other public health scientists. To combat it, scientists have sifted through centuries of literature about how the world coped with past pandemics. A new opinion paper assesses one way in which we might be able to learn from our encounters with
People who are admitted to hospital with Covid-19 can be divided into four distinct groups, according to data from the world’s largest study of patients with the disease. Researchers identified the groups using clinical information and tests carried out upon arrival at hospital to predict the patients’ risk of death – ranging from low to
The COVID-19 pandemic is still raging in India, with over 4.5 million cases, 75.000 deaths and more than 90,000 new cases a day. At present there are few effective therapeutic options, which means that healthcare providers are faced with ongoing challenges in managing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A new study based
The strong pro-inflammatory response known as cytokine storm is said to play an important role in the pathophysiology of a severe variant of covid-19. But researchers at Radboudumc University (Matthijs Kox et al.) doubt that. In a small-scale study published in JAMA, they argue that many studies look at different cytokines and do not make a
