Risk of suicide attempt after diagnosis of dementia

What The Study Did: This comparative effectiveness research study that included a high proportion of non-White individuals assesses whether remdesivir administered alone or with corticosteroids is associated with time to clinical improvement or time to death in patients hospitalized with confirmed COVID-19.

Female adult sockeye from the Fraser River are dying at significantly higher rates than their male counterparts on the journey back to their spawning grounds, finds new UBC research. For every male salmon that doesn't make it to their natal stream, at least two, sometimes three female salmon die. "This is causing skewed sex ratios in their spawning grounds, something that has been observed in recent years," says lead researcher Dr. Scott Hinch, a professor in the faculty of forestry and head of the Pacific Salmon Ecology and Conservation Laboratory at UBC. "The implications on the health of Fraser River stocks are concerning, particularly as Pacific ...

Three-dimensional or "volumetric" images are widely used in medical imaging. These images faithfully represent the 3D spatial relationships present in the body. Yet 3D images are typically displayed on a two-dimensional monitor, which creates a dimensionality mismatch that must be resolved in a clinical setting where practitioners must search a 2D or a 3D image to find a particular trait or target of interest. To learn more about this problem, Craig K. Abbey, Miguel A. Lago, and Miguel P. Eckstein, of the Department of Psychological and Brain Sciences at University of California Santa Barbara, used techniques from the field of vision science to examine how the observers use information in images to perform a given task. Their research, published in the Journal of ...

Syracuse, N.Y. - As opioid use disorders and overdoses continue to skyrocket in the United States, a study by researchers from Syracuse University and Pennsylvania State University shows that unmarried young adults who do not have children are mostly likely to misuse opioids. The growing number of these "disconnected" young adults may also result in continued rises in substance use disorders and overdoses, the researchers say. The study, "Opioid misuse and family structure: Changes and continuities in the role of marriage and children over two decades," was published ...

Living tissue can heal itself from many injuries, but giving similar abilities to artificial systems, such as robots, has been extremely challenging. Now, researchers reporting in ACS' Nano Letters have developed small, swimming robots that can magnetically heal themselves on-the-fly after breaking into two or three pieces. The strategy could someday be used to make hardier devices for environmental or industrial clean up, the researchers say. Watch a video of the self-healing swimmers here. Scientists have developed small robots that can "swim" through fluids ...

Today, Cochrane, a global independent network that gathers and summarizes the best evidence from research to help informed health decision-making, publishes an updated systematic review assessing rapid tests for the detection of SARS-CoV-2 infection (COVID-19). The review shows that rapid antigen tests are better at correctly identifying cases of COVID-19 in people with symptoms than in people without symptoms. There are large differences in the accuracy of different brands of test, with very few meeting the World Health Organization (WHO) minimum acceptable performance standards. During the COVID-19 pandemic, swift diagnosis of people who are infected with SARS-CoV-2 is important. Then decisions ...

The more nitrate there is in mothers' drinking water, the smaller the babies they give birth to. But alarmingly, the declining birth weight can also be registered when the women are exposed to nitrate levels below the EU's threshold of 50 milligrams of nitrate per litre. This is shown by a register-based study of more than 850,000 births in Denmark carried out in a Danish-American partnership led by Professor Torben Sigsgaard from the Department of Public Health at Aarhus University and Professor Leslie Stayner and Dr. Vanessa Coffman from the Division of Epidemiology and Biostatistics at the University of Illinois at Chicago, School of Public Health. On the ...

March 24, 2021 - For premature infants who can't breastfeed on their own, "mother's own milk" (MOM) is by far the best nutrition. There's an urgent need for effective ways to increase the relatively low rates of MOM feeding for preterm infants born to Black and Hispanic mothers. But so far, research has offered little or no specific guidance, concludes an evidence-based review in Advances in Neonatal Care, official journal of the National Association of Neonatal Nurses. The journal is published in the Lippincott portfolio by Wolters Kluwer. Until studies of targeted, culturally appropriate interventions are performed, available evidence points to some promising approaches to overcoming obstacles and facilitating ...

COLUMBIA, Mo. - Nearly 2,000 active landfills are spread across the U.S., with the majority of garbage discarded by homes and businesses finding its way to a landfill. The resulting chemicals and toxins that build up at these sites can then leach into soil and groundwater, and this "leachate" can present serious hazards to the environment and to the people who live nearby. To help environmental agencies battle the toxic threats posed by landfills, researchers at the University of Missouri -- in partnership with the USDA Forest Service -- have developed a system ...
