Intermountain study finds follow-up care with medication, testing after heart attack can prevent 94% of patients from having second cardiac event or death

A new study by Intermountain Healthcare found that following up a cardiac event with a statin prescription and cholesterol measuring blood test prevents 94% of patients from having or dying from a second cardiovascular event. Patients without follow-up care were at a 60% risk, compared to just 6% for those who received treatment.

Study Finds Patients Without Standard Modifiable Heart Risk Factors Are Common and More Likely to Fare Better After Heart Attack Than Patients with Known Factors

Researchers at Intermountain Healthcare discovered that patients without standard modifiable heart risk factors who experience a heart attack fare better, with lower rates of revascularization procedures and subsequent major cardiac events. This finding highlights the need to identify patients at risk for an event before it happens.

Radiation effect simulation software developed for accumulation mechanisms study of radiation damage in nanocrystalline materials

Researchers developed a simulation software to study radiation damage accumulation mechanisms in nanocrystalline materials. The results showed improved radiation resistance due to high grain boundary density, which serves as sinks for radiation-induced vacancies and self-interstitial atoms.

IHMT-CSF1R-833 discovered as potent and selective CSF1R inhibitor

Researchers at Hefei Institutes of Physical Science, Chinese Academy of Sciences, have discovered a potent and selective colony stimulating factor 1 receptor kinase inhibitor. The new compound, IHMT-CSF1R-833, shows high selectivity over human kinases and suppresses tumor-associated macrophage survival and activation.

Decision support tool used in the emergency department reduces rates of death or hospitalization after heart failure

A new decision support tool used in emergency departments has been shown to reduce 30-day all-cause death or cardiovascular hospitalization rates by 12% in heart failure patients. The validated tool, developed using data analytics, helps clinicians determine risk categories and inform admission or discharge decisions.

Conservative management vs. dialysis for preventing hospitalizations in patients with advanced kidney diseases and different ethnicities

Patients with advanced kidney disease may benefit from conservative non-dialytic management over dialysis for hospitalization prevention. Patients of Asian ethnicity show the highest hospitalization rates on early dialysis compared to late dialysis or conservative management. Conservative management underutilized in US due to uncertain...

Mothers' recall of early childhood feeding guidance from health care providers is inconsistent

A new study published in the Journal of Nutrition Education and Behavior found that mothers are least likely to recall being told to limit meals in front of electronic devices. The study analyzed data from the National Survey of Family Growth and found that more than half of mothers recalled only two or three feeding topics, with offer...

Linearly assembled Ag-Cu nanoclusters: Spin transfer and distance-dependent spin coupling

Scientists have successfully assembled linear metal nanoclusters using a novel strategy. The Ag-Cu alloy clusters exhibit spin transfer and distance-dependent spin coupling due to the interaction with sulfur ions. These findings open up new avenues for understanding nanocluster magnetism and developing functional materials.

CABBI team adds powerful new dimension to phenotyping next-gen bioenergy crop

Researchers at CABBI used unmanned aerial vehicles with machine learning methods to select the best candidate genotypes in miscanthus breeding programs. The new method leverages high-resolution aerial imagery and three-dimensional neural networks to estimate crop traits such as flowering time, height, and biomass production.

SARS-CoV-2 outbreaks in care homes for the elderly and disabled in Germany

A comparative epidemiological analysis found a significant decrease in SARS-CoV-2 outbreaks and cases in German care homes following the introduction of COVID-19 vaccination. The median number of cases/outbreaks fell from 21 to 8, while the case-fatality rate decreased from 15.7% to 10.0%.

Extreme temperatures take deadly toll on people in Texas prisons, study finds

A new study published in JAMA Network Open found that extreme temperatures in Texas prisons without climate controls lead to a 30-fold increase in heat-related mortality compared to the general US population. The researchers analyzed data from 2001-2019, finding that even small temperature increases elevate daily risk of death.

Quantum materials enable next-generation photonics and mobile networks in the terahertz regime

Researchers discovered that topological insulators outperform graphene in generating terahertz electromagnetic waves, enabling efficient nonlinear terahertz photonics technology. The study achieved orders of magnitude improvement in output power approaching the milliwatt regime.

Scientists define independent subtype of idiopathic multicentric Castleman disease

Idiopathic plasmacytic lymphadenopathy (IPL) has been confirmed as a distinct clinicopathologically uniform disease, which can be reclassified into an independent subtype of idiopathic multicentric Castleman disease (iMCD). IPL showed greater plasmacytosis and hyperplastic germinal centers compared to non-IPL groups.

Magnetized dead star likely has solid surface

A new study published in Science found that a highly magnetised dead star, known as a magnetar, is likely to have a solid surface with no atmosphere. The research team used data from the NASA satellite IXPE to observe the polarisation of X-ray light emitted by the star, which revealed a signature consistent with a solid crust.
