Using an advanced artificial intelligence tool, researchers at the Icahn School of Medicine at Mount Sinai have identified rare coding variants in 17 genes that shed light on the molecular basis of coronary artery disease (CAD), the leading cause of morbidity and mortality worldwide. The discoveries, detailed in the June 11 online issue of Nature Genetics, reveal genetic factors impacting heart disease that open new avenues for targeted treatments and personalized approaches to cardiovascular care. The investigators used an in silico, or computer-derived, score for coronary artery disease (ISCAD) that holistically represents CAD, as described in a previous paper by the team in The Lancet. The ISCAD score incorporates hundreds of different clinical features from the electronic health record, including vital signs, laboratory test results, medications, symptoms, and diagnoses. To build the score, they trained machine learning models on the electronic health records of 604,914 individuals
In a new study published this week, researchers at the University of South Australia highlight the urgency of ensuring young victims of serious child abuse or neglect get the support they need prior to school commencement so that that can be as close to developmentally on track as possible.
A study led by linguists from the NUS Faculty of Arts and Social Sciences has found that early linguistic signs of dementia can be detected through the study of the natural speech of senior Singaporeans. The novel study revealed that participants with memory-related mild cognitive impairment spoke less and used fewer, but more abstract, nouns that is consistent with the speech pattern of Alzheimer’s patients.
A new study published in Medical Care today showed that substituting registered nurses (RN) with lower-wage staff (e.g. licensed practical nurses, unlicensed assistive personnel) in hospital care is linked with more deaths, readmissions, longer hospital stays, poorer patient satisfaction, and higher costs of care.

In the paper, which was published May 30 in Nature Machine Intelligence, researchers present HypOp, a framework that uses unsupervised learning and hypergraph neural networks.
Building large-scale quantum computers will require the ability to create and control qubits made of industrially relevant materials. Researchers have used atomic-level simulations to understand how the vacancies in silicon carbide that translate into spin-based qubits form and behave. This is an important step toward the future of quantum computing as well as quantum sensing.
in 2022 collaborators - patient groups, basic researchers, and clinicians - conducted a survey and listening sessions with patients, caregivers, and family members affected by impaired smell or taste. They asked about their individual perceptions of the effectiveness of treatments, among other topics.

Having advanced six policies since 2008 to detect and promote treatment of perinatal mental health conditions, the state of Illinois has emerged as a leader in these critical health areas, according to a study by University of Illinois Urbana-Champaign social work professors Karen M. Tabb, center, and Sandra Kopels. U. of I. alumnus Xavier Ramirez co-wrote the paper, published in Frontiers in Psychiatry.
Management consultants and professors seem to be obsessed with visuals. When it comes to strategy, they either pull out their impeccable slides, replete with graphics, or they pick up a marker to sketch out their own frameworks on a whiteboard. This phenomenon has piqued the interest of Felipe Csaszar, professor of strategy.
Americans' interest in a potentially harmful "magic mushroom" is soaring, according to a new study by researchers at the University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science.
A new publication titled “Protection of Participants in Community-Engaged Research by Institutional Review Boards: A Call for Action,” co-authored by Liliane Windsor, PhD, MSW, and Kevin Tan, PhD, MSW, from the University of Illinois Urbana-Champaign School of Social Work, highlights critical shortcomings in the current Institutional Review Board (IRB) processes that hinder community-engaged research (CEnR).
Checkpoint immunotherapy utilizing PD-1 blockade has become the standard of care for metastatic melanoma. While this treatment is effective in 40 percent of patients, the other 60 percent develop resistance, leading to tumor regrowth.
By super cooling a molecule on the surface of brain cells down to about minus 180 degrees Celsius — nearly twice as cold as the coldest places in Antarctica — scientists at Johns Hopkins Medicine say they have determined how a widely-used epilepsy drug works to dampen the excitability of brain cells and help to control, although not cure, seizures.
A new study led by American Cancer Society researchers shows less than one-in-five eligible individuals in the United States were up-to-date with recommended lung cancer screening. The screening uptake was much lower in persons without health insurance or usual source of care and in Southern states with the highest lung cancer burden.
New research from Washington University School of Medicine in St. Louis and other institutions supports earlier findings that indicate that anesthesia is no more hazardous for the brain at higher doses than at lower doses.
As many as 40% of preterm infants in the U.S. suffer from nephrocalcinosis, a condition that deposits excess calcium in kidneys.

The way protons and neutrons move between two nuclei is key to understanding the processes in low-energy nuclear fusion reactions. As the nuclei draw close enough for the nuclear forces to become effective, neutrons and protons can migrate from one nucleus to another, potentially easing the fusion process.
