AI tool screens for heart disease using gut bacteria, study shows

Published

on

Sept. 10 (UPI) — Artificial intelligence can help screen adults for heart disease by detecting specific bacteria in the gut, according to a study published Thursday by the journal Hypertension.

The researchers analyzed stool samples collected from nearly 1,000 patients — half of whom had known heart disease — with their state-of-the-art machine learning modeling tool that runs on artificial intelligence, or AI.

The approach correctly identified clusters of gut bacteria present in those with heart disease, researchers said.

Based on the presence of this bacteria, the AI-based tool correctly identified people with heart disease more than 70% of the time.

“Gut microbiota are associated with the development of hypertension, or high blood pressure, ‘the silent killer’ that often leads to heart disease,” study co-author Bina Joe told UPI.

“Our study shows that there are real changes in the population of these bacteria in our gut that can pinpoint people at risk for heart disease, before hypertension develops,” said Joe, professor and chair of the department of physiology and pharmacology at the University of Toledo.

Nearly half of all U.S. adults have some form of heart disease, and many of them go undiagnosed until they suffer a major event like a heart attack or stroke, according to the American Heart Association.

The new AI-based screening tool could help enhance screening for heart diseases by pinpointing the presence of specific bacteria in the gut, Joe said.

The tool uses historical data on the presence of certain bacteria in patients with high blood pressure or heart disease to identify those at risk for the conditions — based on whether they too have the same bacteria — she said.

The gut microbiome is made up of microorganisms, including bacteria, that live in the digestive tracts of humans and are involved in the digestion of food and processing of nutrients.

In recent years, bacteria in the gut has been linked with overall health beyond the digestive tract, Joe said. Recent studies have also suggested that the presence of certain bacteria can increase risk for heart disease.

Because the composition of the bacteria in the gut varies from person to person, it has been challenging to develop a test that accurately identifies the bacteria that increases heart disease risk.

The AI-based tool, however, still is in the early stages of development, and it may be several years before doctors can use it to identify at-risk patients, Joe said.

“The gut microbiome is highly variable among individuals, so we were surprised by the promising level of accuracy obtained from these preliminary results,” she said.

“It is conceivable that clinicians could analyze the gut microbiome of patients’ stool samples with our machine learning method to screen patients for heart and vascular diseases.”

Asthma, food sensitivity linked to irritable bowel syndrome in study

Published

on

Teens who had asthma and food hypersensitivity when they were younger are at increased risk of irritable bowel syndrome, researchers report.

For the study, the investigators examined the health of 2,770 children from birth to age 16. Kids with IBS at age 16 were more likely to have had asthma at age 12, about 11% versus 7%.

In addition, the researchers found that 16-year-olds with IBS were more likely to have had food hypersensitivity at age 12, 41% versus 29%.

Asthma, food hypersensitivity and eczema — a condition that makes your skin red and itchy — were all associated with an increased risk of concurrent IBS at age 16, the findings showed.

“The associations found in this large study suggest there’s a shared pathophysiology between common allergy-related diseases and adolescent irritable bowel syndrome,” said study leader Jessica Sjölund, of the Institute of Medicine at the University of Gothenburg, in Sweden.

Sjölund noted that previous studies on allergy-related diseases and IBS have been contradictory.

These new findings could lead to development of new treatments for adolescent IBS, targeting processes of low-grade inflammation seen in the allergy-related diseases, she said.

The study findings were scheduled for presentation Monday at a United European Gastroenterology virtual meeting. Research presented at meetings should be considered preliminary until published in a peer-reviewed journal.

IBS affects more than one in 10 people and is the most common functional gastrointestinal disorder, the study authors noted in a meeting news release. It can cause abdominal cramps, bloating, diarrhea and constipation, and can be extremely disabling for patients.

Hans Törnblom is a leading IBS expert in Europe who was involved in the research. He said, “Even though functional gastrointestinal disorders are common, many patients are, unfortunately, negatively stigmatized and labeled. The fact that many IBS sufferers do not seek medical advice should be of great concern.”

Cancer takes heavy toll on women’s work, finances, study shows

Published

on

Young women with cancer are at a high risk for employment and financial consequences, a new study finds.

“Our study addresses the burden of employment disruption and financial hardship among young women with cancer — a group who may be at particular risk for poor financial outcomes after cancer given their age and gender,” said researcher Clare Meernik, a fellow at the University of North Carolina at Chapel Hill’s Lineberger Comprehensive Cancer Center.

She and her colleagues surveyed more than 1,300 women in North Carolina and California a median of seven years after diagnosis. Their cancer was diagnosed when they were 15 to 39 years of age and working.

Following their diagnosis, 32% of the women had to stop working or cut back on their hours. Twenty-seven percent said they had to borrow money, go into debt or file for bankruptcy because of cancer treatment.

Women with disrupted employment were more likely — by 17 percentage points — to have these problems than women who were able to keep working.

Half of the women said they were stressed about their big medical bills, and women with disrupted employment were more likely to suffer psychological distress by 8 percentage points than women who were able to keep working.

The findings were published online Oct. 12 in the journal Cancer.

“Our findings highlight the need for effective interventions to promote job maintenance and transition back to the workforce after cancer treatment, as well as increased workplace accommodations and benefits, to improve cancer outcomes for young women,” Meernik said in a journal news release.

Study: Less restrictive reproductive rights reduce birth complications risk by 7%

Published

on

Oct. 13 (UPI) — Women living in states with less restrictive reproductive rights policies are 7% less likely have low birth weight babies than those living in states with more stringent laws, according to an analysis published Tuesday by the American Journal of Preventive Medicine.

The risk was 8% lower for Black women living in less-restrictive states, the data showed.

“Our study provides evidence that reproductive rights policies play a critical role in advancing maternal and child health equity,” study co-author May Sudhinaraset, of the UCLA Fielding School of Public Health, said in a statement.

Since the Supreme Court‘s decision in Roe v. Wade in 1973, which effectively legalized abortion, states have had “substantial discretion” in creating policies governing whether Medicaid covers the costs of contraception or reproductive health care.

Some states have taken steps that effectively limit access to abortion services and other reproductive care, Sudhinaraset and her colleagues said.

Black women are more likely to die in pregnancy and childbirth than any other race group, experience more maternal health complications than White women and generally have lower quality maternity care, they said.

In addition, women of color are more likely to experience adverse birth outcomes.

Compared to infants of normal weight, low-birth-weight babies face many potential health complications, including infections early in life and long-term problems, such as delayed motor and social development or learning disabilities.

Sudhinaraset and her colleagues analyzed birth record data for the nearly 4 million births that occurred in the 50 states and Washington, D.C., in 2016, comparing reproductive rights policies and adverse birth outcomes in each state.

They also evaluated if the associations were different for women of color and immigrants.

The findings indicate that expanding reproductive rights may reduce the risk of low-birth weight, particularly for U.S.-born Black women, the researchers said.

“Important policy levers can and should be implemented to improve women’s reproductive health overall, including increasing abortion access and mandatory sex education in schools,” Sudhinaraset said.
