ROCHESTER, Minn. — Mayo Clinic researchers have developed a calculation that can help identify moderate aortic stenosis patients at higher risk of dying from the condition. According to new research published in Mayo Clinic Proceedings, calculating the patient's mean arterial pressure (AugMAP) is a simple and effective way to identify those patients who may benefit from more aggressive treatment strategies. "Physiologically, AugMAP can be considered a marker of global left ventricular contractile function," says Chieh-Ju Chao, M.D., senior associate consultant in the Mayo Clinic Department ...

Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths. Mathematicians from Imperial College London and the University of Nottingham have, for the first time, used machine learning to expand and accelerate work identifying ‘atomic shapes’ that form the basic pieces of geometry in higher dimensions. Their findings have been published in Nature Communications. The way they used artificial intelligence, in the form of machine learning, could transform how maths is done, say the authors. Dr Alexander Kasprzyk from ...

Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a study led by UK Centre for Ecology & Hydrology (UKCEH) researchers. The study, which involved one of the largest and most wide-ranging analyses of long-term monitoring data in the world – spanning over 30 years, found improvements in invertebrate biodiversity across all regions and river types in England. This improvement is all the more surprising given English rivers are amongst the most highly exposed to wastewater and other pressures in Europe. The recent State of Nature report shows that the overall abundance of species in Great ...

Cancer immunotherapy drugs called PD-1 inhibitors are widely used to stimulate the immune system to fight cancer, but many patients either don’t respond or develop resistance to them. A new small-molecule drug candidate being tested in an early-stage clinical trial aims to improve patient responses to immunotherapy.  Now scientists have shown, in a study published today in Nature, that the small molecule works through two different mechanisms to slow tumor growth and increase survival in lab animals.  Researchers from the Tumor ...

In a study on the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with crash risk among older adult drivers, researchers at Columbia University Mailman School of Public Health found that older adult drivers with ADHD are at a significantly elevated crash risk compared with their counterparts without ADHD. Outcomes included hard- braking events, and self-reported traffic ticket events, and vehicular crashes. Until now research on ADHD and driving safety was largely limited to ...

About The Study: This study found that the burden of respiratory syncytial virus (RSV)-associated hospitalizations in Canadian pediatric hospitals was substantial, particularly among infants less than six months of age, and RSV hospitalizations increased in 2021-2022 compared with the pre-pandemic period, while severity of illness remained similar. These findings suggest that RSV preventive strategies for infants less than six months of age would be associated with decreased RSV disease burden in children.  Authors: Jesse Papenburg, ...

About The Study: Based on U.S. national representative data, the estimated attention-deficit hyperactivity disorder (ADHD) prevalence was 10.08% to 10.47% among children and adolescents ages 4 to 17 from 2017 to 2022, which was similar to the prevalence from the National Health Interview Survey in 2015 to 2016 (10.20%). No significant annual change in the prevalence of ADHD was found from 2017 to 2022. Notably, the estimated prevalence of ADHD among individuals in the U.S. in this study was higher than worldwide estimates (5.3%) in earlier years (1978-2005). Authors: Wenhan Yang, M.D., Ph.D., of Guangdong ...

About The Study: In this post hoc secondary analysis of 10,678 participants with atherosclerotic cardiovascular disease from a randomized clinical trial, enteric-coated aspirin was not associated with significantly higher risk of heart attack, stroke, or death or with lower bleeding risk compared with uncoated aspirin, regardless of dose, although a reduction in bleeding with enteric-coated aspirin cannot be excluded. More research is needed to confirm whether enteric-coated aspirin formulations or newer formulations will improve outcomes in this population. Authors: Mark B. Effron, M.D., of the University of Queensland-Ochsner Clinical School in New Orleans, is the corresponding ...

Robots built by engineers at the University of California San Diego helped achieve a major breakthrough in understanding how insect flight evolved, described in the Oct. 4, 2023 issue of the journal Nature. The study is a result of a six-year long collaboration between roboticists at UC San Diego and biophysicists at the Georgia Institute of Technology.  The findings focus on how the two different modes of flight evolved in insects. Most insects use their brains to activate their flight muscles each wingstroke, just like we activate the muscles in our legs ...

Main points: New research has overturned the traditional view that natural rock weathering acts as a CO2 sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivalling that of volcanoes. The results have important implications for modelling climate change scenarios but at the moment, CO2 release from rock weathering is not captured in climate modelling. Future work will focus on whether human activities may be increasing CO2 release from rock weathering, and how this could be managed. A new study led by the University of Oxford has overturned the view ...

Philadelphia, October 2, 2023 – Researchers from the Center for Injury Research and Prevention (CIRP) at Children’s Hospital of Philadelphia (CHOP) and the Stuart Weitzman School of Design at the University of Pennsylvania have found that teenagers living in lower-income areas of the Columbus, Ohio metro area are up to four times less likely to complete driver training and obtain their driver’s license before age 18. Long travel times to driving schools also impacted enrollment in driver education, affecting those from both higher- and lower-income areas. The findings, originally published in the journals Accident Analysis and Prevention ...

Researchers at Vanderbilt-Ingram Cancer Center have discovered a druggable target on natural killer cells that could potentially trigger a therapeutic response in patients with immunotherapy-resistant, triple-negative breast cancer. Currently, only about 15% of early-stage, triple-negative breast cancer patients benefit from combining immunotherapy, drugs that target immune cells to attack the tumor, with chemotherapy. Identifying why most patients don’t respond is critical for personalizing treatment plans and minimizing therapy ...

Researchers have discovered a sea’s worth of water locked within the sediment and rock of a lost volcanic plateau that’s now deep in the Earth’s crust. Revealed by a 3D seismic image, the water lies two miles under the ocean floor off the coast of New Zealand, where it may be dampening a major earthquake fault that faces the country’s North Island. The fault is known for producing slow-motion earthquakes, called slow slip events. These can release pent-up tectonic pressure harmlessly over days and weeks. Scientists want to know why they happen more often at some ...

Dads can suffer from postpartum depression, and a new pilot study at the University of Illinois Chicago suggests they can and should be screened for the condition. Given the intertwined effects of mothers’ and fathers’ physical and mental health, addressing the health of fathers may be a powerful untapped tool in improving the nation’s ongoing maternal health crisis.  The researchers got mothers’ permission to interview and screen 24 dads, 30% of whom screened positive for postpartum depression on the same tool ...
