Fewer people than previously reported suffer from stroke as a result of COVID-19, a new analysis finds. However, strokes that accompany the pandemic virus, SARS-CoV-2, appear to be more severe.
In the NYU Grossman School of Medicine-led study, researchers found that fewer than 1 percent of hospitalized patients who tested positive during one month for the virus also suffered from a stroke. This contrasts with the rates reported recently in small studies in China and Italy, which ranged from 2 - 5 percent.
SEATTLE (May 20) - Without access to soap and clean water, more than 2 billion people in low- and middle-income nations - a quarter of the world's population - have a greater likelihood of acquiring and transmitting the coronavirus than those in wealthy countries.
That's the conclusion of a new study by the Institute for Health Metrics and Evaluation at the University of Washington's School of Medicine.
The automatic operation and maintenance of optical network is important for ensuring information communication and network operation. The growing variety of services has forced operation and maintenance personnel to face tremendous operational pressure. A recent study has constructed a control architecture called intent defined optical networks (IDON) to cope with the issue.
Oxidation of primary alcohols to carboxylic acids is of importance in both organic chemistry and chemical industry because the oxidation products can be used to prepare various pharmaceuticals and useful chemicals. Photocatalytic oxidation process has been considered as a sustainable technology to achieve the selective oxidation under ambient conditions with irradiation from solar light.
Zombies or enemies flashing right before your eyes and the dizzying feeling of standing on the edge of a cliff using virtual reality and augmented reality (AR and VR) are no longer exclusive to the games or media industries. Those technologies allow us to conduct virtual conferences, share presentations and videos, and communicate in real time in the virtual space. But because of the high cost and bulkiness of VR and AR devices, the virtual world is not within easy reach.
Observations made with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the telltale signs of a star system being born. Around the young star AB Aurigae lies a dense disc of dust and gas in which astronomers have spotted a prominent spiral structure with a 'twist' that marks the site where a planet may be forming. The observed feature could be the first direct evidence of a baby planet coming into existence.
The vast majority of young people who self-harm or experience suicidal thoughts appear to have only mild or moderate mental distress, instead of more obvious symptoms associated with a diagnosable disorder, according to a new study.
As such, measures to reduce suicide risk in young people should focus on the whole population, not just those who are most distressed, depressed or anxious, said Cambridge University researchers during Mental Health Awareness week.
Maternal antenatal corticosteroid treatment is standard care when there is a risk for preterm delivery. The treatment improves the prognosis of babies born preterm. However, a new study conducted by experts from the University of Helsinki, University of Oulu and THL Finnish Institute for Health and Welfare shows that children exposed to maternal antenatal corticosteroid treatment have higher rates of emotional, behavioral and psychological development disorders than nonexposed children.
Tests on new designs for next-gen solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia’s Monash University, incorporating 3D-printed key components.
The machine can analyse 16 sample perovskite-based solar cells simultaneously, in parallel, dramatically speeding up the process.
The invention means that the performance and commercial potential of new compounds can be very rapidly evaluated, significantly speeding up the development process.
Speciation is the process by which new species forms and is the driving force of biodiversity. Since Darwin published On the Origin of Species, great efforts have been performed without interruption to explore the pattern and mechanism of speciation. It is well acknowledged that determining the forms of reproductive isolation and their relative importance in species divergence is of critical importance for our understanding of speciation.
Boston, Mass. - With nearly 5 million confirmed cases globally and more than 300,000 deaths from COVID-19, much remains unknown about SARS-CoV-2, the virus that causes the disease. Two critical questions are whether vaccines will prevent infection with COVID-19, and whether individuals who have recovered from COVID-19 are protected against re-exposure. A pair of new studies led by researchers at Beth Israel Deaconess Medical Center (BIDMC) sheds new light on these questions. Both studies were published today in the journal Science.
Two new studies in macaques offer hope that humans could develop protective immunity against SARS-CoV-2, either as the result of a natural infection or by way of a vaccine. While there are differences between SARS-CoV-2 infection in macaques and humans, these findings - some of the first to show that non-human primates can develop protective immunity to SARS-CoV-2 - are promising in light of the ongoing efforts around the world to develop a vaccine and antibody treatments for COVID-19.
Climate scientists from the IBS Center for Climate Physics discover that, contrary to previously held beliefs, Neanderthal extinction was neither caused by abrupt glacial climate shifts, nor by interbreeding with Homo sapiens. According to new supercomputer model simulations, only competition between Neanderthals and Homo sapiens can explain the rapid demise of Neanderthals around 43 to 38 thousand years ago.
Birth control pills are an effective and safe form of birth control; however, they are associated with a number of side effects, including mood alterations. A recent research study from Aarhus University has shown that women who take birth control pills have a much higher level of the hormone oxytocin, also called the love hormone, in their blood compared to non-users. This study, published in Scientific Reports, helps to understand why birth control pills affect emotional life.
The pressure to send home more patients increases when hospital beds are in short supply.
For example, you have a greater chance of being discharged on a Friday or the day before a holiday. The chance of being discharged on days when the hospital is full due to high activity may also be greater, which can have very serious consequences for patients.
