New Study Demonstrates Value of AI-Enabled EKG Algorithm in Routine Practice Written by AZoRoboticsMay 7 2021 There are several forms of heart disease, but some types of this medical condition, like asymptomatic low ejection fraction, can be difficult to detect, particularly during the early stages when therapies would be highly effective. Image Credit: Mayo Clinic. The EAGLE—short for ECG AI-Guided Screening for Low Ejection Fraction—trial attempted to establish whether an artificial intel...

New Infrared Imager Converts Infrared Light into Clear Images Written by AZoOpticsMay 6 2021 Imagine mapping out an individual’s blood vessels while simultaneously monitoring heart rate without making contact with the person’s skin, seeing through fog and smog, and seeing through silicon wafers to check the composition and quality of electronic boards. The new infrared imager is thin and compact with a large-area display. Image Credit: Ning Li. The above examples are just a few of the capa...

Study shows why some stroke patients do not have abnormal heart rhythms Scientists have shed light on why some people who have a stroke do not also have abnormal heart rhythms, even though their hearts contain similar scar tissue. Their results, published today in eLife, could help identify the best treatments for people who might be at risk of recurrent stroke, new heart disorders, or both. Strokes are often caused by abnormal blood flow resulting from rapid, irregular beating in the upper ch...

Juvenile incarceration does not reduce the probability of future convictions Harsh prison sentences for juvenile crimes do not reduce the probability of conviction for violent crimes as an adult, and actually increase the propensity for conviction of drug-related crimes, finds a new study by economists at UC Riverside and the University of Louisiana. Harsh juvenile sentences do reduce the likelihood of conviction for property crimes as an adult. But the increase in drug-related crimes cancels o...

Frontline clinician scientists recommend more proactive guidelines to deal with pandemics A new editorial written by clinical academics working on the frontline of the Covid-19 pandemic has warned that national guidelines need to adapt in the face of pandemics. Published in The BMJ today (Friday), the article considers that guidance developed by national bodies was slow to appear during the first and second waves of the pandemic, leaving local providers unsupported when making many critical t...

Older adults find connection and meaning in community, demonstrate resilience during pandemic Older adults were significantly affected by isolation and stress during Oregons initial COVID-19 lockdown last spring, but they were also able to find connection and meaning in community, new hobbies and time for themselves, a recent Oregon State University study found. If resilience is understood as the ability to see positives in the midst of a negative situation, then many of the studys participants...

People living with a child attending in-person schooling have high risk of COVID-19 People living with a child who attends school in-person have an increased risk of reporting evidence of COVID-19, but teacher masking, symptom screening, and other mitigation measures in schools may be able to minimize that excess risk, suggests a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. For their study, the researchers analyzed nearly 600,000 responses from an ongoing Fac...

Study Shows the Significant Effect of Climate Change on Central African Forests A global research work coordinated by scientists from the Institut de Recherche pour le Développement (IRD) and CIRAD has disclosed the composition of the tropical forests in Central Africa and their susceptibility to the rising pressure from human activity and climate change predicted in the forthcoming years. Gradient of the vulnerability of Central African forests to climate change and increased human pressure...

POT1 gene linked to glioma development mediates its effects in a sex-specific manner Researchers at Baylor College of Medicine and collaborators at other institutions have discovered that POT1, a gene known to be associated with risk of glioma, the most common type of malignant brain tumor, mediates its effects in a sex-specific manner. Researchers found that female mice with glioma that lacked the gene survived less than males. This led them to investigate human glioma cells, where they found ...

Household income explains more discrepancy in food security than any other factor One of the most comprehensive statistical analyses of drivers of food insecurity across 65 countries has concluded that household income consistently explains more discrepancy in food security than any other factor, including agricultural land resources and production. The Thayer School of Engineering at Dartmouth study, "Cross-national analysis of food security drivers: comparing results based on the Food Insecur...
