A study in Neurology found a digital clock-drawing test may help detect pathology related to Alzheimer's disease within five minutes in asymptomatic patients. The DCTclock was able to separate older adults with normal cognitive function from those with cognitive disorders.
Implantable photonic neural probes may expand the use of light-sheet fluorescence microscopy for deep brain imaging in moving animals, according to research in Neurophotonics. "This new implantable photonic neural probe technology for generating light sheets within the brain circumvents many of the constraints that have limited the use of light-sheet fluorescence imaging in experimental neuroscience," said researcher Wesley Sacher.
A deep learning model that provides patients with two-year risk scores for breast cancer "were more predictive ... than age and mammographic density," Dr. Brian Dontchos said during a presentation at the Society of Breast Imaging/American College of Radiology Breast Imaging Symposium. Researchers also found higher cancer detection rates among patients with breast cancer categorized in the intermediate- and high-risk groups after undergoing a BI-RADS 0 screening mammography exam after an initial BI-RADS 1 or 2 index screening exam.
Higher consumption of red and processed meat was linked to poorer cardiac function, adverse ventricular remodeling and higher arterial stiffness, while higher consumption of oily fish was linked to greater arterial compliance and better ventricular function, according to a study presented at the virtual ESC Preventive Cardiology 2021. The findings were based on data from 19,408 individuals with cardiovascular magnetic resonance imaging data.
The number of new COVID-19 cases in the US fell by 0.4% for the week ending April 18, following four consecutive weeks of increase, but the country still logged almost 70,000 new cases per day last week as variants continue to spread. The average number of patients hospitalized with COVID-19 climbed by 5% to over 41,000, marking the third straight weeks of increase, while related fatalities dropped 2.8%.
The FDA has updated regulations for certain medical devices, including three radiology software products -- picture archiving and communications systems, medical image storage devices and medical image communication devices. The rules are effective immediately.
The CDC could decide by Friday if restrictions will be added to the Johnson & Johnson vaccine after six women reported blood clotting issues after receiving the shot, according to National Institute of Allergy and Infectious Diseases Director Anthony Fauci. The US paused use of J&J's vaccines last week.
Combining genomic data with health outcomes data in EHRs can provide deeper insight into population health disparities than simple race and ethnicity data, and may improve health equity and outcomes, according to a study published in Cell. Embedding genomic data and using it to infer genetic ancestry "will allow the development of evidence-based means to utilize race and ethnicity, genetic ancestry, and the socioeconomic determinants of health for both rare and common diseases," researchers wrote.
