Patients in a hospital's intensive care unit are kept under close observation: clinicians continuously monitor their vital signs such as their pulse, blood pressure and blood oxygen saturation. This furnishes doctors and nurses with a wealth of data about the condition of their patients' health. Nevertheless, using this information to predict how their condition will develop or to detect life-threatening changes far in advance is anything but easy.
Québec City, March 9, 2020 - Bacteria may be involved in the development of type 2 diabetes, according to a study published today in Nature Metabolism by researchers from Université Laval, the Québec Heart and Lung Institute (IUCPQ), and McMaster University.
The authors found that the blood, liver, and certain abdominal fat deposits in diabetics have a different bacterial signature than in non-diabetics.
Natural environments are constantly changing. If the change is a familiar one--like the shift from day to night or fluctuation in food supply--organisms use gene regulation to adapt, allowing individual genes to be turned on and off as needed. However, an organism may face fundamentally new conditions for which it has not yet evolved an adequate gene regulation mechanism.
CHAPEL HILL, NC - March 9, 2020 - Scientists at the UNC School of Medicine and colleagues created a new computational tool called H-MAGMA to study the genetic underpinnings of nine brain disorders, including the identification of new genes associated with each disorder.
Boston, MA - Proposed changes to the federal Supplemental Nutrition Assistance Program (SNAP) may result in as many as one in ten U.S. families losing SNAP benefits, and potential impacts are unknown. A new study led by the Harvard Pilgrim Health Care Institute examines the potential effects of the proposed SNAP eligibility changes on health and health care affordability. The study, "Socioeconomic and Health Characteristics of Families at Risk for Losing Supplemental Nutrition Assistance Program Benefits", appears in JAMA Internal Medicine on March 9.
A star that pulsates on just one side has been discovered in the Milky Way about 1500 light years from Earth. It is the first of its kind to be found and scientists expect to find many more similar systems as technology to listen inside the beating hearts of stars improves.
Mitochondria cannot autonomously cope with stress and must instead call on the cell for help. Molecular geneticists at Ludwig-Maximilians-Universitaet (LMU) in Munich have identified the long-sought signaling pathway which enables the organelles to do so.
People say they are more willing to approach cute-looking monkeys in the wild, but in reality end up getting closer to dominant monkeys they believe could pose more risk, according to new research.
Researchers at the University of Lincoln, UK, showed a sample of people photos of wild Barbary macaques - a primate which commonly mingles with tourists in Gibraltar and North Africa - and asked them to assess their faces according to a variety of traits including dominance, trustworthiness, cuteness and socialness.
PHILADELPHIA - Poverty takes a toll on health in many ways. It often causes malnutrition and hunger, creates barriers to access basic resources, and can also impact well-being in more subtle ways linked to social discrimination and exclusion. Nurses, one of the most important healthcare providers, serve both as advocates for patients and as their most constant caregivers. They are trained to provide compassionate care to all.
March 9, 2020 - Less than half of patients with sports-related mild traumatic brain injury (mTBI) achieve clinical recovery within two weeks after injury, reports a study in Clinical Journal of Sport Medicine. The journal is published in the Lippincott portfolio by Wolters Kluwer.
CAMBRIDGE, MA -- One promising new strategy to treat diabetes is to give patients insulin that circulates in their bloodstream, staying dormant until activated by rising blood sugar levels. However, no glucose-responsive insulins (GRIs) have been approved for human use, and the only candidate that entered the clinical trial stage was discontinued after it failed to show effectiveness in humans.
An international study published in the journal Cell, has described 109 genetic variants associated with eight psychiatric disorders: autism, ADHD, schizophrenia, bipolar disorder, depression, obsessive-compulsive disorder and Tourette Syndrome, in a total of about 230,000 patients worldwide.
Denver--March 9, 2020--Including smoking cessation with existing lung cancer screening efforts would reduce lung cancer mortality by 14 percent and increase life-years gained by 81 percent compared with screening alone, according to a study from Rafael Meza from the University of Michigan and colleagues and published in the Journal of Thoracic Oncology, a publication of the International Association for the Study of Lung Cancer.
Groundwater is the largest source of freshwater, one of the world's most precious natural resources and vital for crops and drinking water. It is found under our very feet in the cracks and pores in soil, sediments and rocks. Now an international research team led by the University of Göttingen has developed the first global computer model of groundwater flow into the world's oceans. Their analysis shows that 20% of the world's sensitive coastal ecosystems - such as estuaries, salt marshes and coral reefs - are at risk of pollutants transported by groundwater flow from the land to the sea.
Ouch, you've cut your finger! As you fumble to grab a tissue, the paramedics in your blood are already rushing to the scene. These blood cells, called platelets, morph in shape from round to spiny, sticking to each other and to the injured blood vessel walls, to begin patching the gash. The platelets join together with other proteins to form a mesh-like plug--a clot--to stop the bleeding.
