(Press-News.org) ROCHESTER, Minn. — Earlier research showed that primary care clinicians using AI-ECG tools identified more unknown cases of a weak heart pump, also called low ejection fraction, than without AI. New study findings published in Mayo Clinic Proceedings: Digital Health suggest that this type of screening is also cost-effective in the long term, especially in outpatient settings.
Incremental drops in heart function are treatable with medication but can be hard to spot. Patients may or may not have symptoms when their heart is not pumping effectively, and doctors may not order an echocardiogram or other diagnostic test to check ejection fraction unless there are symptoms. Peter Noseworthy, M.D., a Mayo Clinic cardiologist and co-author of the study, notes that using AI to catch the hidden signals of heart failure during a routine visit can mean earlier treatment for patients, delaying or stopping disease progression, and fewer related medical costs over time.
According to the study, the cost-effectiveness ratio of using AI-ECG was $27,858 per quality-adjusted life year — a measure of the quality of life and years lived. The program was especially cost-effective in outpatient settings, with a much lower cost-effectiveness ratio of $1,651 per quality-adjusted life year.
The researchers studied the economic impact of using the AI-ECG tool by using real-world information from 22,000 participants in the established EAGLE trial and following which patients had weak heart pumps and which did not. They simulated the progression of disease in the longer term, assigning values for the health burden on patients and the resulting effect on economic value.
"We categorized patients as either AI-ECG positive, meaning we would recommend further testing for low ejection fraction, or AI-ECG negative with no further tests needed. Then we followed the normal path of care and looked at what that would cost. Did they have an echocardiogram? Did they stay healthy or develop heart failure later and need hospitalization? We considered different scenarios, costs and patient outcomes," says Xiaoxi Yao, Ph.D., a professor of Health Services Research at Mayo Clinic.
Dr. Yao, who is the senior author of the study, notes that cost-effectiveness is an important aspect of the evaluation of AI technologies when considering what to implement in clinical practice.
"We know that earlier diagnosis can lead to better and more cost-effective treatment options. To get there, we have been establishing a framework for AI evaluation and implementation. The next step is finding ways to streamline this process so we can reduce the time and resources required for such rigorous evaluation," says Dr. Yao.

After decades of plantation agriculture, coconut palms dominate over half of Pacific atoll forests
2024-12-04
(Santa Barbara, Calif.) — Coconut palms are king throughout the tropics, serving as the foundation for human lives and cultures across the Pacific Ocean for centuries. However, 200 years of planting by colonial interests transformed the palm from the revered “Tree of Life” to a cash crop monoculture grown on Pacific atolls for a singular purpose — production of coconut oil (copra) for export around the world.
Despite wide interest in the global footprint of palm crops, the distribution of coconut palms across tropical Pacific atolls has received little attention. Until now. Published in Environmental Research Letters, ...

Study shows significant rise in psychotherapy use among adults, but gains are uneven across socioeconomic groups
2024-12-04
Access to psychotherapy has risen substantially among U.S. adults with mild to moderate distress since 2018, according to a new study from Columbia University’s Mailman School of Public Health and the Department of Psychiatry at Columbia Vagelos College of Physicians and Surgeons. The increase in psychotherapy use is particularly notable among younger adults, women, college-educated individuals, and those with higher family incomes. Privately insured individuals also experienced greater gains in psychotherapy use compared to those who are publicly insured or uninsured. The findings are published ...
The bisexual population in Stockholm has doubled in a decade
2024-12-04
Over the past decade, the proportion of residents in Stockholm County who identify as bisexual has nearly doubled. The younger generations are driving the trend and many of them have previously identified as heterosexual. This is according to a study published in JAMA Network Open by researchers at Karolinska Institutet in collaboration with the Centre for Epidemiology and Community Medicine within Region Stockholm in Sweden.
The researchers analysed data from the Stockholm Public Health Cohort, covering more than 98,000 individuals from 2002 to 2021. The proportion of people ...
From snapshots to motion: watching biology in action
2024-12-04
Choosing a film for a movie night is always a battle. Now imagine if you could pick one that provided a window into some of the most fundamental biological processes that keep us alive. For the first time ever, researchers have captured a real-time molecular movie to show how two essential cellular processes – transcription and translation – interact with each other in bacteria.
In all living organisms, DNA contains the code that defines cellular structures and functions. An enzyme called RNA polymerase deciphers this code and converts it into RNA, a molecule ...
Trends in outpatient psychotherapy among adults in the US
2024-12-04
About The Study: This study found that psychotherapy use increased significantly faster among several socioeconomically advantaged groups and that inequalities were evident in teletherapy access. These trends and patterns highlight a need for clinical interventions and health care policies to broaden access to psychotherapy including teletherapy.

Obstetric care access at rural and urban hospitals in the US
2024-12-04
About The Study: Between 2010 and 2022—a time of tremendous attention to maternal health—there was a net loss of hospital-based obstetric care in both rural and urban hospitals across the U.S. In 2010, more than half of rural hospitals and two-thirds of urban hospitals offered obstetric care. Rural hospitals started with lower percentages of hospitals offering obstetrics compared with urban hospitals and experienced a larger increase in the percentage of hospitals without obstetrics.

Key breakthrough in autism: pivotal role of CPEB4 condensates revealed
2024-12-04
A study by IRB Barcelona unveils how the lack of a fraction of the CPEB4 protein causes a decrease in the expression of genes that are crucial for neuronal development.
Published in the journal Nature, the study opens new avenues for the development of targeted treatments for autism.
Barcelona, 4 December 2024 –Autism is a neurodevelopmental disorder characterised by difficulties in communication and social behaviour. Approximately 20% of cases are linked to a specific genetic mutation, but the origin of the remaining 80%, known as idiopathic autism, remains a mystery.
A team of scientists led by Drs. Raúl Méndez and Xavier Salvatella at the Institute ...
Neural signature could show the way to recovery from trauma
2024-12-04
Researchers at UCSF find a brain signature of resilience in mice that suggests a new way of treating severe depression.
Some people bounce back from trauma, but others get caught in depressive loops that sap the joy from their lives.
Now, scientists at UC San Francisco are learning how the brain creates these divergent experiences. They hope it will help them find a way to treat those who struggle with long-lasting symptoms of stress.
The researchers found that stress changes activity in a brain circuit ...
Research reveals how fructose in diet enhances tumor growth
2024-12-04
Fructose consumption has increased considerably over the past five decades, largely due to the widespread use of high-fructose corn syrup as a sweetener in beverages and ultra-processed foods. New research from Washington University in St. Louis shows that dietary fructose promotes tumor growth in animal models of melanoma, breast cancer and cervical cancer. However, fructose does not directly fuel tumors, according to the study published Dec. 4 in the journal Nature.
Instead, WashU scientists discovered that the liver converts fructose into usable nutrients for cancer cells, a compelling finding that could open up new avenues for care and treatment ...
