A new study comparing the incidence of sudden deaths occurring outside the hospital across New York City's highly diverse neighborhoods with the percentage of positive SARS-CoV-19 tests found that increased sudden deaths during the pandemic correlate to the extent of virus infection in a neighborhood. The analysis appears in Heart Rhythm, the official journal of the Heart Rhythm Society, the Cardiac Electrophysiology Society, and the Pediatric & Congenital Electrophysiology Society, published by Elsevier.
A student infected with COVID-19 returning home from university for Christmas would, on average, have infected just less than one other household member with the virus, according to a new model devised by mathematicians at Cardiff University and published in Health Systems.
Scientists at Washington University School of Medicine in St. Louis have shown that a relatively simple and rapid blood test can predict which patients with COVID-19 are at highest risk of severe complications or death. The blood test measures levels of mitochondrial DNA, which normally resides inside the energy factories of cells. Mitochondrial DNA spilling out of cells and into the bloodstream is a sign that a particular type of violent cell death is taking place in the body.
A University of Saskatchewan study has found that the COVID-19 pandemic has led to significant worsening of already poor dietary habits, low activity levels, sedentary behaviour, and high alcohol consumption among university students.
COVID-19 deaths are indeed different from other lung failure deaths, according to two recent studies, with 56% of COVID-19 patients dying primarily from the lung damage caused by the virus, compared with 22% of those whose lungs fail due to other causes. But, the researchers conclude, the kind of care needed to help sustain people through the worst cases of all forms of lung failure is highly similar, and just needs to be fine-tuned.
As the vaccination of older adults against COVID-19 begins across the country, new poll data suggests that many of them don't yet have access to the 'patient portal' online systems that could make it much easier for them to schedule a vaccination appointment. The poll finds that 45% of adults aged 65 to 80, and 42% of adults aged 50 to 80, said they hadn't set up an account with their health provider's portal system.
Scientists studying the body's natural defenses against bacterial infection have identified a nutrient--taurine--that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could aid efforts seeking alternatives to antibiotics.
With access to treatment, HIV has become a lifelong chronic condition for the majority of 38 million people living with it. Understanding how it affects the brain over time is increasingly important for improving both treatment and quality of life. A new study of brain scans of 1,203 HIV-infected adults across 5 continents found that with people with lower white blood cell counts also had less brain volume in the hippocampus and thalamus.
Researchers have developed a DNA test to quickly identify secondary infections in COVID-19 patients, who have double the risk of developing pneumonia while on ventilation than non-COVID-19 patients.
An analysis of the first 250,000 patients admitted to hospital with coronavirus reveals a high mortality and inequities in the quality of healthcare across regions
