Scientists receive $12-million grant to explore molecular mechanisms of heart injury and repair

Heart disease is a leading cause of death worldwide. But significant disparities exist in the incidence and severity of heart disease, particularly between men and women, and major barriers remain for the successful long-term care of heart disease patients.

A systematic framework to reintroduce cardiovascular diagnosis and treatment care during COVID-19

The American Heart Association, together with 14 cardiovascular societies in North America, today issued joint guidance, "Safe Reintroduction of Cardiovascular Services during the COVID-19 Pandemic: Guidance from North American Society Leadership," to outline a systematic, phased approach to safely reintroducing cardiovascular procedures for diagnosis and treatment during the COVID-19 pandemic.

Hydroxychloroquine shown to slow recovery for COVID-19 patients

As researchers try to piece together a therapeutic strategy against the ongoing COVID-19 pandemic, a recent retrospective study from Cleveland Clinic Abu Dhabi, assessed the Hydroxychloroquine's efficacy in increasing SARS-CoV-2 viral clearance, finding that it appeared to significantly slow viral clearance in mild to moderately ill COVID-19 patients.

Different types of white fat may play distinct roles in metabolic diseases

Excess white fat causes obesity, which in turn can drive diabetes and many other metabolic diseases that are growing at epidemic rates around the world.

Air ambulance service may lead to surprise bills for many patients

When an emergency dispatcher calls for a helicopter or plane to fly a critically ill patient to a hospital, they don't have time to check whether they take the patient's insurance.

Scientists are exploring to find the 'Achilles heel' of coronavirus

Coronavirus, or more exactly SARS-CoV-2, has the world in its grip. How does the virus manage to bind to cells in the human body? How does it gain entry to the cell? How does it hijack the cell's machinery to make it help to replicate the viral genome?

COVID-19 progression linked to B cell activation

The disease course of COVID-19 is diverse, ranging from asymptomatic to fatal respiratory failure. Scientists have been working to uncover the immunological reasons behind this heterogeneity. A recent study on B cells, published on the preprint server medRxiv in April 2020, shows that extrafollicular B cells could be a marker of severe infection in the early stages, predicting the need for earlier immunomodulatory therapy.

Study: Brazilian president’s attitude to coronavirus increases 'risky behavior' in the country

Jair Bolsonaro's public undermining of pandemic prevention efforts reduces social distancing in the parts of Brazil where his voter base is strongest, according to a new study using location data from over 60 million phones.

Researchers discover a new way to reduce implant rejection

The team from the University of Nottingham's Schools of Pharmacy and Life Sciences have found that the surface shape (topography) and chemical composition of polymer materials can be changed to create materials that control the body's immune response.

Loss of smell may be related to neuroinvasive propensity of SARS-CoV-2

The novel coronavirus has rapidly infected millions over the world in over 187 countries and territories, causing hundreds of thousands of deaths. One of the often-neglected and under-reported symptoms of the virus is the loss of the sense of smell or anosmia. Now, a new study out of Germany published on the preprint server medRxiv in April 2020 provides a quantified estimate of the magnitude of anosmia as a symptom of the coronavirus.

Uncovering immune cell reactions in COVID-19

A new study published on the preprint server medRxiv in April 2020 suggests that an overactive immune response is responsible for the more severe manifestations of the illness.

Asymptomatic carriers transmit SARS-CoV-2 with normal breathing

The coronavirus disease (COVID-19) first emerged in a seafood market in Wuhan City, Hubei Province, China, in December 2019. Since then, it has spread to 187 countries, infecting more than 3.58 million people. The novel coronavirus spreads rapidly partly due to asymptomatic carriers. Now a new study shows that asymptomatic carriers may transmit the virus by merely breathing.

Loss of smell should be listed as early symptom of COVID-19

Though the two common symptoms are cough and fever, recent studies and reports point to a loss of smell as a symptom early in the disease process. A team of researchers at the Technical University Dresden (TU Dresden) revealed that the sudden loss of smell is experienced by many patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Human endemic coronavirus reinfection possible after recovery

The novel coronavirus started spreading in December 2019, and since then, it has rippled across the globe, affecting 187 countries and territories, and infecting more than 3.18 million people. However, the behavior and mechanism of the virus, including whether it provides adaptive immunity, is still unclear. There have been reports of reinfection out of South Korea and Japan

Dead virus fragments are causing COVID-19 reinfection false positives

The coronavirus disease (COVID-19) has ravaged across the globe, infecting a staggering 3.5 million people, and taking over 251,000 lives. One of the most significant concerns in this global pandemic is the possibility of reinfection as previous reports in South Korea and Japan show people testing positive with the coronavirus again.

Analysis of India's battle with COVID-19

A new paper published on the preprint server medRxiv in April 2020 suggests, based on mathematical models, that premature removal of lockdown restrictions in India could be highly counterproductive, enhancing the secondary spread of COVID-19, pushing up the number of fatalities and prolonging the course of the pandemic in India.

Study reveals an unprecedented pace and openness in COVID-19 research

The early academic response to coronavirus disease (COVID-19) was specified by research aiming to define the disease, with prompt response from all scholarly publishing stakeholders and short manuscript turnaround times, shows a new study available on the medRxiv* preprint server.

New information on viral antigens could improve COVID-19 testing

Researchers in France and China have characterized antibody responses to a wide range of antigens present on severe acute respiratory syndrome-related coronavirus (SARS-CoV-2) among patients with coronavirus disease 2019 (COVID-19).

Artificial intelligence model can distinguish between pneumonia and COVID-19 from chest x-rays

A research team from Valencia's Polytechnic University, from the CVBLab, has developed a predictive artificial intelligence model that can tell the difference between healthy patients, those who are ill with pneumonia and those who have COVID-19, from chest x-rays.
