Many children of low-income families across the country do not have access to quality health care. Lack of health care can have a domino effect, affecting educational outcomes in the classroom. School-based telehealth could offer a sustainable and effective solution, according to a new report in the Journal for Nurse Practitioners by Kathryn King Cristaldi, M.D., the medical director of the school-based telehealth program, and Kelli Garber, the lead advanced practice provider and clinical integration specialist for the program. The program through the MUSC Health Center for Telehealth has effectively served over 70 schools across the state of South Carolina. Evaluating a child at school via telehealth ...

Probiotics -- those bacteria that are good for your digestive tract -- are short-lived, rarely taking residence or colonizing the gut. But a new study from researchers at the University of California, Davis, finds that in breast milk-fed babies given the probiotic B. infantis, the probiotic will persist in the baby's gut for up to one year and play a valuable role in a healthy digestive system. The study was published in the journal Pediatric Research. "The same group had shown in a previous study that giving breast milk-fed babies B. infantis had beneficial effects that lasted up to 30 days after supplementation, but this is the first study to show persistent colonization up to 1 year of age," said lead author Jennifer Smilowitz with the UC Davis Department ...

Non-alcoholic steatohepatitis (NASH), often called 'fatty liver hepatitis', can lead to serious liver damage and liver cancer. A team of researchers at the Technical University of Munich (TUM) has discovered that this condition is caused by cells that attack healthy tissue - a phenomenon known as auto-aggression. Their results may help in the development of new therapies to avoid the consequences of NASH. Fatty liver disease (NASH) is often associated with obesity. However, our understanding of the causes has been very limited. A team working with ...

Rich false memories of autobiographical events can be planted - and then reversed, a new paper has found. The study highlights - for the first time - techniques that can correct false recollections without damaging true memories. It is published by researchers from the University of Portsmouth, UK, and the Universities of Hagen and Mainz, Germany. There is plenty of psychological research which shows that memories are often reconstructed and therefore fallible and malleable. However, this is the first time research has shown that false memories of autobiographical events can be undone. Studying how memories are created, identified ...

Infants prefer baby talk in any language, but particularly when it's in a language they're hearing at home. A unique study of hundreds of babies involving 17 labs on four continents showed that all babies respond more to infant-directed speech -- baby talk -- than they do to adult-directed speech. It also revealed that babies as young as six months can pick up on differences in language around them. "We were able to compare babies from bilingual backgrounds to babies from monolingual backgrounds, and what seemed to matter the most was the match between the language they ...

A new study is the first to identify how human brains grow much larger, with three times as many neurons, compared with chimpanzee and gorilla brains. The study, led by researchers at the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK, identified a key molecular switch that can make ape brain organoids grow more like human organoids, and vice versa. The study, published in the journal END ...

Scientists have genetically engineered immune cells, called myeloid cells, to precisely deliver an anticancer signal to organs where cancer may spread. In a study of mice, treatment with the engineered cells shrank tumors and prevented the cancer from spreading to other parts of the body. The study, led by scientists at the National Cancer Institute's (NCI) Center for Cancer Research, part of the National Institutes of Health (NIH), was published March 24, 2021, in Cell. "This is a novel approach to immunotherapy that appears to have promise as a potential treatment for metastatic cancer," said the study's leader, Rosandra Kaplan, M.D., of NCI's Center for Cancer Research. Metastatic cancer--cancer that has spread from its original location to other parts of the body--is notoriously ...

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 ...

HOUSTON - (Mar 24, 2021) -The mammalian center for learning and memory, hippocampus, has a remarkable capacity to generate new neurons throughout life. Newborn neurons are produced by neural stem cells (NSCs) and they are crucial for forming neural circuits required for learning and memory, and mood control. During aging, the number of NSCs declines, leading to decreased neurogenesis and age-associated cognitive decline, anxiety, and depression. Thus, identifying the core molecular machinery responsible for NSC preservation is of fundamental importance if we are to use neurogenesis to halt or reverse hippocampal age-related pathology. While there are increasing number of tools available to study NSCs and neurogenesis in mouse models, one of the major ...

Sickle cell disease is the most prevalent inherited blood disorder in the world, affecting 70,000 to 100,000 Americans. However, it is considered an orphan disease, meaning it impacts less than 200,000 people nationally, and is therefore underrepresented in therapeutic research. A team led by Abhishek Jain from the Department of Biomedical Engineering at Texas A&M University is working to address this disease. "I'm trying to create these new types of disease models that can impact health care, with the long-term goal of emphasizing on applying these tools ...

> CATONSVILLE, MD, March 24, 2021 - COVID-19 has been shown to spread on airplanes by infected passengers, so minimizing the risk of secondary infections aboard aircraft may save lives. New research in the INFORMS journal Service Science uses two models to help solve the airplane seating assignment problem (ASAP). The models can lower the transmission risk of COVID-19 more so than the strategy of blocking the middle seats, given the same number of passengers. "Blocking the middle seat on an airplane may provide limited benefit in reducing the risk of transmission of COVID-19. Rather, other health protocols are better supported at preventing the transmission ...

SARS-CoV-2, the virus responsible for the COVID-19 pandemic, arrived one year ago and turned our lives upside-down. While worldwide vaccination programs are currently ongoing, we do not yet know for how long the vaccine will provide immune protection against infection, and if the currently approved vaccines can provide protection against the emerging virus variants. In addition, it appears that vaccines cannot prevent illness for people who have already been infected. In contrast to vaccines, there are currently no effective drugs that act against the virus SARS-CoV-2. New research by Associate Professor Jasmin Mecinovic and co-workers from the Department of Physics, Chemistry and Pharmacy, University of Southern Denmark, now presents a compound that might provide a basis for the ...

Decarbonizing the economy and achieving the transition from fossil fuels to renewable energies is one of the most urgent global challenges of the 21st century. Hydrogen can play a key role in this process as a promising climate-neutral energy vehicle. Yet, the so-called green hydrogen economy requires that hydrogen production be based exclusively on renewable energy. In addition, it should ideally not use expensive and rare metal catalysts, whose production has severe environmental consequences. To address this challenge, ITQB NOVA researchers Inês Cardoso Pereira and Mónica Martins are working on an innovative technology to produce hydrogen from light using non-photosynthetic microorganisms. Hydrogen offers exciting new possibilities as an energy vehicle, ...

The Event Horizon Telescope (EHT) collaboration, a multinational team of over 300 scientists including two astrophysicists from the University of the Witwatersrand (Wits University), has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core. "We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful ...
