Philadelphia, January 18, 2021 - 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. "Our research shows the highly diverse regional distribution of out-of-hospital sudden death during ...

ANN ARBOR, Mich. -- An estimated one in five teenagers has symptoms of a mental health disorder such as depression or anxiety, and suicide is the second leading cause of death among teens. But the first person a teen confides in may not always be an adult - they may prefer to talk to another teen. And three-quarters of parents in a new national poll think peers better understand teen challenges, compared to teachers or counselors in the school. The majority also agree that peer support leaders at school would encourage more teens to talk with someone about their mental health problems, according to the C.S. Mott Children's Hospital National Poll on Children's Health at Michigan Medicine. "Peers may provide valuable support for ...

New research examining more than 800,000 traffic stops in Vermont over the course of five years substantiates the term "driving while Black and Brown." Compared to white drivers, Black and Latinx drivers in Vermont are more likely to be stopped, ticketed, arrested, and searched. But they are less likely to be found with contraband than white drivers. The report finds evidence not only of racial disparities but also racial bias in policing. What's more, a number of these gaps widened over the years examined in the report. With such comprehensive data encompassing the state of Vermont, the authors also found that Vermont police stop cars at a rate ...

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 END ...

Variation in consumption of market-acquired foods outside of the traditional diet -- but not in total calories burned daily -- is reliably related to indigenous Amazonian children's body fat, according to a Baylor University study that offers insight into the global obesity epidemic. "The importance of a poor diet versus low energy expenditure on the development of childhood obesity remains unclear," said Samuel Urlacher, Ph.D., assistant professor of anthropology at Baylor University, CIFAR Azrieli Global Scholar and lead author of the study. "Using gold-standard measures of energy expenditure, we show that relatively lean, rural forager-horticulturalist children in the Amazon spend approximately the same total number of calories each day as their much ...

Spiritualist mediums might be more prone to immersive mental activities and unusual auditory experiences early in life, according to new research. This might explain why some people and not others eventually adopt spiritualist beliefs and engage in the practice of 'hearing the dead', the study led by Durham University found. Mediums who "hear" spirits are said to be experiencing clairaudient communications, rather than clairvoyant ("seeing") or clairsentient ("feeling" or "sensing") communications. The researchers conducted a survey of 65 clairaudient spiritualist mediums from the Spiritualists' National Union and 143 members of the general population in the ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have discovered that fruit flies with genetic modifications to enhance glucose uptake have significantly longer lifespans. Looking at the brain cells of aging flies, they found that better glucose uptake compensates for age-related deterioration in motor functions, and led to longer life. The effect was more pronounced when coupled with dietary restrictions. This suggests healthier eating plus improved glucose uptake in the brain might lead to enhanced lifespans. The brain is a particularly power-hungry part of our bodies, consuming 20% of the oxygen we take in and 25% of the glucose. That's why it's so important that it can stay powered, ...

The spread of COVID-19 in Brazil overwhelmed the health systems in all the country's regions, particularly in areas where they were already fragile, according to a collaborative effort involving the Barcelona Institute for Global Health (ISGlobal), an institution supported by the "la Caixa" Foundation, the University of Sao Paulo, the Catholic University of Rio de Janeiro, the D'Or Institute of Research and Education and the Oswaldo Cruz Foundation. The findings, published in The Lancet Respiratory Medicine, reveal that a large percentage of COVID-19 patients that were hospitalised in Brazil required intensive care and respiratory support, and many did not survive. The COVID-19 pandemic has put an enormous strain on healthcare ...

BOSTON - The Study on Stress, Spirituality and Health (SSSH), a cutting-edge proteomics analysis, suggests that religious beliefs modulate protein expression associated with cardiovascular disease in South Asians in the United States. The research, published by investigators from Massachusetts General Hospital (MGH) and Beth Israel Deaconess Medical Center (BIDMC) and the University of California San Francisco (UCSF) in Scientific Reports, demonstrates that spiritual struggles, in particular, significantly modify the impact of unique proteins on risk of developing cardiovascular disease (CVD) in U.S. South Asians, a community that has especially ...

One of the most vexing aspects of the COVID-19 pandemic is doctors' inability to predict which newly hospitalized patients will go on to develop severe disease, including complications that require the insertion of a breathing tube, kidney dialysis or other intensive care. Knowledge of a patient's age and underlying medical conditions can help predict such outcomes, but there are still surprises when younger, seemingly healthier patients suffer severe complications that can lead to death. Now, scientists at Washington University School of Medicine in St. Louis have shown that a relatively simple and rapid blood test can predict -- within a day of a hospital admission -- which patients with ...

MIAMI--A group of more than 60 scientists have provided recommendations to improve the Indian Ocean Observing System (IndOOS), a basin-wide monitoring system to better understand the impacts of human-caused climate change in a region that has been warming faster than any other ocean. The group, led by Lisa Beal, professor of ocean sciences at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, provides a road map for an enhanced IndOOS to better meet the scientific and societal needs for more reliable environmental forecasts in the next decade. The 136 actionable recommendations from the three-year, internationally coordinated review were published in the Bulletin of the American Meteorological Society. The scientists call for four major ...

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. The findings of the study--the first to assess changes in students' dietary intake, physical activity, and sedentary behaviour before and during the pandemic--are published today in the journal Applied Physiology, Nutrition and Metabolism. "Our findings are important because university students, especially those most vulnerable for poor nutrition and sedentary behaviour, should be targeted for interventions aimed at maintaining and improving physical activity and dietary practices during this pandemic and beyond," said lead author ...

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 all adults aged 50 to 80, said they had not set up an account with their health provider's portal system. That's according to the newly analyzed data from the National Poll on Healthy Aging, based at the University of Michigan's Institute for Healthcare Policy and Innovation. The new number actually represents some progress: 49% of adults in the same age range hadn't set up patient portal access the last time the ...

Exactly what kills a person with COVID-19? How do those deaths differ from the deaths of people whose lungs fail rapidly because of other infections or injuries? And what can hospital teams pressed into service on overtaxed COVID-19 wards do to try to keep patients from dying, despite strained circumstances? All of these questions have sparked discussion - and even conspiracy theories - since the pandemic began. Now, two studies from Michigan Medicine may help answer them. The bottom line: COVID-19 deaths are indeed different from other lung failure deaths. 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. It just needs to be fine-tuned to focus on the ...

Scientists have uncovered new clues implicating a type of herpes virus as the cause of a central nervous system disease in monkeys that's similar to multiple sclerosis in people. The findings, published in the Annals of Clinical and Translational Neurology, expand on previous work to understand the cause of the disease and potentially develop antiviral therapies. The work was led by scientists at Oregon Health & Science University. "This gives us a better understanding of the model," said Scott Wong, Ph.D., senior author of the study and a scientist at the OHSU Vaccine and Gene Therapy Institute and the Oregon National Primate Research Center. "It draws more parallels to MS in people." The new study reveals the presence of two kinds of T cells, a type of ...

In groundbreaking materials research, a team led by University of Minnesota Professor K. Andre Mkhoyan has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows--transparency and conductivity. The researchers are the first to observe metallic lines in a perovskite crystal. Perovskites abound in the Earth's center, and barium stannate (BaSnO3) is one such crystal. However, it has not been studied extensively for metallic properties because of the prevalence of more conductive materials on the planet like metals or semiconductors. The ...

Osaka, Japan - A team of scientists from Osaka University, The University of Queensland, and the National University of Singapore's Faculty of Engineering used tiny nanodiamonds coated with a heat-releasing polymer to probe the thermal properties of cells. When irradiated with light from a laser, the sensors acted both as heaters and thermometers, allowing the thermal conductivity of the interior of a cell to be calculated. This work may lead to a new set of heat-based treatments for killing bacteria or cancer cells. Even though the cell is the fundamental unit of all living organisms, some physical properties have remained difficult to study in vivo. For example, a cell's thermal conductivity, as well as the rate that heat can flow through an object if ...

Berkeley -- Most frogs emit a characteristic croak to attract the attention of a potential mate. But a few frog species that call near loud streams -- where the noise may obscure those crucial love songs -- add to their calls by visually showing off with the flap of a hand, a wave of a foot or a bob of the head. Frogs who "dance" near rushing streams have been documented in the rainforests of India, Borneo, Brazil and, now, Ecuador. Conservation ecologist Rebecca Brunner, a Ph.D. candidate at the University of California, Berkeley, has discovered that the glass frog ...

Plant pathologists working at universities across 26 corn-producing states in the United States and in Ontario, Canada, compiled data about annual corn reductions caused by diseases. Estimated loss from each disease varied greatly by region. "This group of plant pathologists takes a step back to estimate what has gone wrong in corn fields in each of their states," said Iowa State University plant pathologist Daren Mueller, who was involved in this project. "Collectively, and across years, corn disease loss estimates provide folks a zoomed out view of what diseases are affecting corn in the U.S. and Canada." To Mueller, these data represent one of the pieces of a good research project. Researchers can use these data to justify new research projects that can help mitigate the impacts ...

The U.S. fishing and seafood sector generated more than $200 billion in annual sales and supported 1.7 million jobs in recent years. It experienced broad declines in 2020 as a result of the COVID-19 public health crisis, according to a new NOAA Fisheries analysis released today. While losses vary by sector, by region and by industry, data and information from this report may help businesses and communities assess losses and inform long-term recovery and resilience strategies. According to analysts, COVID-19 protective measures instituted in March across the United States and globe contributed to an almost-immediate impact on seafood sector sales. There was a strong start to the year, with ...

Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process - and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But what if one could convince the unengaged parts of a catalyst to get involved? Chemical reactions could occur faster or more efficiently. Stanford University material scientists led by Jennifer Dionne have done just that by using light and advanced fabrication and characterization techniques to endow catalysts with new abilities. In a proof-of-concept experiment, rods of palladium that were approximately 1/200th the width of a human hair served as catalysts. ...

COLUMBIA, Mo. - When he was in middle school, teachers would give Sam Curran a list of words to type in a computer to practice his vocabulary. But Sam, who has autism, was unable to stay focused on the task and required a significant amount of one-to-one direction from a teacher to complete his work. After his mother, Alicia, persuaded his teachers to allow Sam to change the colors of the words, he was able to complete work more independently and began making remarkable progress. Now 20 years old, Sam's mother continues to ensure his special interests are leveraged in an effort to continue to help him grow and develop. A new survey from the MU Thompson Center for Autism and Neurodevelopmental Disorders has found that similar strategies for children with disabilities can help reduce anxiety ...

A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding and developing treatments for RNA-related diseases, including spinal muscular atrophy and perhaps even the novel coronavirus. "RNA folding is a dynamic process that is fundamental for life," said Northwestern's Julius B. Lucks, who led the study. "RNA is a really important piece of diagnostic and therapeutic design. The more we know about RNA folding and complexities, the better we can design treatments." Using data from RNA-folding experiments, the researchers generated the first-ever data-driven movies of how RNA folds as it is made by cellular ...

Nearly 38 million people around the world are living with HIV, which, with access to treatment, has become a lifelong chronic condition. Understanding how infection changes the brain, especially in the context of aging, is increasingly important for improving both treatment and quality of life. In January, researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (USC Stevens INI), part of the Keck School of Medicine of USC, and other international NeuroHIV researchers, published one of the largest-ever neuroimaging studies of HIV. The researchers pooled magnetic resonance imaging (MRI) data from 1,203 HIV-positive individuals across Africa, ...

The White-lipped peccary Tayassu pecari is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil's Atlantic Rainforest, they prefer the fruit of the jussara palm Euterpe edulis. The jussara is very abundant in this biome, probably thanks to vast amounts of dung, urine, and soil trampling by peccaries as well as tapirs (Tapirus terrestris) and other fruit-eating animals, or frugivores. This behavior releases forms of nitrogen, a key element in plant growth. A study supported ...
