There’s a lot of talk about the potential for artificial intelligence in medicine, but few researchers have shown through well-designed clinical trials that it could be a boon for doctors, health care providers and patients.

Now, researchers at Stanford Medicine have conducted one such trial; they tested an artificial intelligence algorithm used to evaluate heart function. The algorithm, they found, improves evaluations of heart function from echocardiograms — movies of the beating heart, filmed with ultrasound waves, that show how efficiently it pumps blood.

“This blinded, randomized clinical trial is, to our knowledge, one of the first to evaluate the performance of an artificial intelligence algorithm in medicine. We showed that AI can help improve accuracy and speed of echocardiogram readings,” said James Zou, PhD, assistant professor of biomedical data science and co-senior author on the study. “This is important because heart disease is the leading cause of death in the world. There are over 10 million echocardiograms done each year in the U.S., and AI has the potential to add precision to how they are interpreted.”

NIH-funded study supports new role for nutrient found in fish, dietary supplements.

Omega-3 fatty acids, which are abundant in fish and fish oil supplements, appear promising for maintaining lung health, according to new evidence from a large, multi-faceted study in healthy adults supported by the National Institutes of Health. The study provides the strongest evidence to date of this association and underscores the importance of including omega-3 fatty acids in the diet, especially given that many Americans do not meet current guidelines. Funded largely by the National Heart, Lung, and Blood Institute (NHLBI), part of NIH, the study results were published in the American Journal of Respiratory and Critical Care Medicine.

Could this be the future of medicine?

In order for chatbots to be useful to doctors and other health professionals, they are going to need access to the latest research. But current models simply don’t have access to data beyond their latest update. Daniel Nadler has been working to resolve this issue with his new startup OpenEvidence.

He plans to achieve his lofty goal by “marrying these language models with a real-time firehose of clinical documents,” Nadler told Forbes on Thursday. He claims that his new model “can answer with an open book, as opposed to a closed book.”

As if all that isn’t enough, now doctors are saying women with PCOS need to think about their heart health as well, says Erin Michos, M.D., associate director of preventive cardiology at the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease.

“Women worry about infertility, acne and weight gain but might not be thinking of high blood pressure and type 2 diabetes. It’s important to know that they’re at an increased risk and how important diet and exercise is,” says Michos.

Reducing reliance of aninmal experimentation. 🐀

According to the team, this new unparalleled technology facilitates the precise manipulation of biological materials, enabling the creation of highly sophisticated and realistic organoids that closely mimic the complexity of the corresponding human organs.

The cutting-edge magnetic and acoustic levitation will bioprint heart models to improve protection against radiation both in space and on Earth.

After being awarded nearly 4 million euros by the European Innovation Council’s Pathfinder Open, PULSE is aiming to foster technological innovations to improve human health and pave the way for safer and more sustainable space exploration.

Multi-Levitation bioprinting and creating realistic organoids

The device, designed by PULSE, combines magnetic and acoustic levitation into an innovative bioprinting platform capable spatiotemporal control of cell deposition.

This groundbreaking study, which was published as the cover article in the journal Science, not only sheds light on our evolutionary history but also paves the way for a future where physicians could more accurately assess a patient’s likelihood of suffering from ailments like back pain or arthritis later in life.

“Our research is a powerful demonstration of the impact of AI in medicine, particularly when it comes to analyzing and quantifying imaging data, as well as integrating this information with health records and genetics rapidly and at large scale,” said Vagheesh Narasimhan, an assistant professor of integrative biology as well as statistics and data science, who led the multidisciplinary team of researchers, to provide the genetic map of skeletal proportions.

A new neuroimaging study has found that individuals who consumed their first alcoholic drink before the age of 18 had weaker connections in the brain’s cognitive control network compared those who consumed their first alcoholic drink after the age of 18. This suggests that starting to drink alcohol at a young age might make this brain network less effective. The study was published in Psychiatry Research: Neuroimaging.

Although the adverse effects of alcohol consumption and related long-term health risks are well known, it is estimated that 30% of youth in the United States use alcohol by the eighth grade. 62% of adolescents report drinking their first alcoholic drink by the time they graduate from high school, around 18 years of age.

Studies have found that individuals who start using alcohol earlier are more likely to develop alcohol-related problems later in life. Individuals who drink their first alcoholic drink earlier are also more likely to get drunk for the first time at an earlier age. They are also more likely to participate in binge drinking i.e., to consume more than 5 standard drinks for men or more than 4 for women on a single occasion.
