Black patients from disadvantaged neighborhoods were significantly more likely to die within five years of surviving a heart attack compared with Black heart attack patients from wealthier neighborhoods and white patients of any socioeconomic means who survive a heart attack, according to a study being presented at the American College of Cardiology's 70th Annual Scientific Session.

Patients suffering a heart attack received percutaneous coronary intervention (PCI), a procedure to clear blocked arteries in the heart, an average of 10 minutes faster after clinicians and paramedics began using an app to facilitate efficient hospital intakes for these patients, according to a study being presented at the American College of Cardiology's 70th Annual Scientific Session.

Collaborative research between the University of Kentucky (UK) and University of Southern California (USC) suggests that a noninvasive neuroimaging technique may index early-stage blood-brain barrier (BBB) dysfunction associated with small vessel disease (SVD).

The recommendations come from an international team, led by McMaster University. The international guideline panel included 22 health-care professionals, school administrators, and parents of children with and without food allergy, along with a team of six researchers with methodology expertise. A systematic literature review of practices for managing food allergy in schools found a lack of high-quality evidence, so the guideline recommendations are graded as conditional.

Mammals see with their eyes, hear with their ears and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore require an extended ability to navigate? Scientific experiments led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) ) now show that the cornea of the eyes is the location of such an important sense in migrating bats.

Research led by the Garvan Institute of Medical Research has for the first time mapped the unique genetic profile of the skeleton's 'master regulator' cells, known as osteocytes.

Current guidelines for managing osteoporosis specifically call out hip or spine fractures for increasing the risk for subsequent bone breaks. But a new UCLA-led study suggests that fractures in the arm, wrist, leg and other parts of the body should also set off alarm bells. A fracture, no matter the location, indicates a general tendency to break a bone in the future at a different location,

A study involving researchers at Karolinska Institutet and Gothenburg University in Sweden has found that low levels of a protein called PDGFRb are associated with particularly good results of radiotherapy in women with early-stage breast cancer. The study, which is published in the journal Clinical Cancer Research, also suggests that the efficacy of radiotherapy can be improved with drugs that block this protein.

Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.

We here describe a new species of pelomedusoid turtle from a geological formation in Madagascar otherwise known for its exquisitely preserved fossil birds, dinosaurs, and crocodilians. The new turtle possesses an unusually flattened skull combined with a particularly gracile lower jaw and enlarged tongue bones, which not only must have given it a frog-like appearance, but also suggests that it was a specialized suction feeder that fed on small-bodied living prey using quick strikes.

Stress levels of moms with preschoolers soared during the pandemic, with twice as many of the mothers reporting they lost sleep during the COVID-19 outbreak than before it. Mothers, especially those with preschoolers, need a lot more than flowers on Mother's Day.... What moms really need is more support, from their family, workplaces and communities. They need systemic change."

Consumers are less forgiving of brand failures when algorithms are anthropomorphized, use machine learning, or are used for subjective or interactive tasks.

The population growth of an endangered butterfly species is greatest in habitats with microclimatic variability, demonstrates a study carried out collaboratively by the Faculty of Biological and Environmental Sciences and the Helsinki Institute of Life Science of the University of Helsinki as well as the Finnish Environment Institute.

To improve our own health and the health of our planet, dietary habits will need to change. Because the composition of an optimal diet changes depending on the combination of location, season, and personalized dietary needs, investigators have built a tool that uses an extensive database of food items, nutrients, and environmental-impacts to develop optimized diets specific to an individual in a given country and month.

A new study published in the British Journal of Educational Technology has identified the different needs of students across primary, middle, and high school related to online learning during the COVID-19 pandemic.

When investigators in the UK recorded the calls of migratory birds called thrushes at night, they found that call rates were up to five times higher over the brightest urban areas compared with darker villages.

A new study provides a profile of teachers around the world who provide English Medium Instruction (EMI) in higher education, in which the English language is used to teach academic subjects (other than English itself) in countries where the first language is not English.

An analysis of published studies indicates that Twitter may be a useful learning tool in dental education.

Virtual care provided through telephone or videoconference has been broadly implemented in recent months because of the COVID-19 pandemic. A new analysis of published studies has examined the accuracy and reliability of virtual compared with in-person cognitive assessments for diagnosing dementia or mild cognitive impairment.

Erythropoietin (EPO) is a medication used to stimulate the production of new red blood cells, which is impaired in individuals with kidney failure. Unfortunately, however, the treatment may increase the risk of hip fractures.
