UC San Diego School of Medicine researchers discovered that SARS-CoV-2, or at least its genetic signature, abounds on hospital surfaces, often co-locating with one particular type of bacteria.
In a new study published in Nature, Dan Barouch, MD, PhD, Director of BIDMC's Center for Virology and Vaccine Research, and colleagues report on the antibody and cellular immune responses generated by the Ad26.COV2.S vaccine against the original viral strain and against SARS-CoV-2 variants of concern. The team found that this vaccine induced immune responses against all the viral variants.
A new study from Washington University School of Medicine in St. Louis suggests that, among men, low testosterone levels in the blood are linked to more severe COVID-19. The study contradicts widespread assumptions that higher testosterone may explain why men, on average, develop more severe COVID-19 than women do.
As the global race for COVID-19 vaccination continues, new research from the University of South Australia shows that the uptake of vaccines could be vastly improved if approved vaccine brands received more positive promotion and media coverage.
A paper published today in JAMA Network Open presents early results of the global effort to gather information about the incidence, severity and outcomes of neurological manifestations of COVID-19 disease.
University of Miami Miller School of Medicine researchers report the widespread blood vessel dysfunction, or endothelial dysfunction, that results from the COVID-19 infection could contribute to erectile dysfunction, or ED, according to a study published in the World Journal of Men’s Health .
A new study from Washington University School of Medicine in St. Louis shows that even mild cases of COVID-19 increase the risk of death in the six months following diagnosis and that this risk increases with disease severity. The comprehensive study also catalogues the wide-ranging and long-term health problems often triggered by the infection, even among those not hospitalized.
A research project led by the UCLA Fielding School of Public Health has found that Los Angeles County neighborhoods with poor air quality had the highest death rates from the pandemic.
In a study that looked at racial differences in outcomes of COVID-19 patients admitted to the intensive care unit, researchers at Henry Ford Hospital in Detroit found that patients of color had a lower 28-day mortality than white patients. Race, however, was not a factor in overall hospital mortality, length of stay in the ICU or in the rate of patients placed on mechanical ventilation, researchers said. The findings, published in Critical Care Medicine, are believed to be one of the first in the United States to study racial differences and outcomes specific to patients hospitalized in the ICU with COVID-19.
Investigators from UC San Diego and UCLA report COVID-19 infection rates for a cohort of health care workers previously vaccinated for the novel coronavirus. Risk of infection is minuscule, but exists.
A comprehensive review published today in Nature Medicine offers an initial glimpse of the multi-organ effects of long-term COVID-19 and suggests a framework for the care of COVID-19 long-haulers through dedicated, multidisciplinary clinics.
A new survey of dozens of surge capacity managers at hospitals nationwide captures the U.S. health care system’s pandemic preparedness status in the months before the first COVID-19 cases were identified in China.
Using molecular dating tools and epidemiological simulations, researchers at UC San Diego School of Medicine estimate that the SARS-CoV-2 virus likely circulated undetected for two months before the first human cases of COVID-19 were described in Wuhan, China in late-December 2019.
A Michigan Medicine team’s online guidelines have been viewed more than 30,000 times by providers in 150 countries since the beginning of the pandemic--and their deployment of an effective COVID-19 therapy has been a model for health systems and hospitals statewide.
Last fall, many older adults were on the fence about getting a COVID-19 vaccine, according to a poll taken in October. But a new poll taken in late January shows a large uptick in positive attitudes, including among people over 50 who are Black, Hispanic or in fair or poor health.
New research from Washington University School of Medicine in St. Louis has found that new variants of the virus that causes COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic, potentially undermining the effectiveness of vaccines and antibody-based drugs now being used to prevent or treat COVID-19.
A new study from Washington University School of Medicine in St. Louis provides evidence that COVID-19 patients’ heart damage is caused by the virus invading and replicating inside heart muscle cells, leading to cell death and interfering with heart muscle contraction. The researchers used stem cells to engineer heart tissue that models the human infection and could help in studying the disease and developing possible therapies.
Spread of a new variant of SARS-CoV-2 in the New York City region that shares worrisome similarities with other recent variants has been identified by scientists at Columbia University.
UC San Diego School of Medicine researchers are using stem cell-derived organoids to study how SARS-CoV-2 interacts with various organ systems. Their findings may help explain the wide variety in COVID-19 symptoms and aid the search for therapies.
COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing; however, speaking while near one another is also risky. In Physics of Fluids, scientists used smoke and laser light to study the flow of expelled breath near and around two people conversing in various relative postures commonly found in the service industry, such as in hair salons, medical exam rooms, or long-term care facilities.
