(Press-News.org) February 17, 2025 – Less than one in five patients are tested for cardiovascular risk factors following pregnancy-related hypertension or diabetes, according to a new study published in the "Go Red for Women" issue of Circulation.
Cardiovascular diseases are a leading cause of death among women. People who develop hypertensive disorders of pregnancy or gestational diabetes are at a higher risk of experiencing a future stroke or heart disease. Screening for high blood pressure, lipids, and sugars plays a crucial role in the early diagnosis of risk factors for cardiovascular disease.
"There's increasing evidence that maternal health during pregnancy is associated with long-term vascular health,” says Dr. Amy Yu, neurologist and senior scientist at Sunnybrook Research Institute, and adjunct scientist with ICES.
“Guidelines recommend that women with high blood pressure or sugar during pregnancy should have their blood sugar and cholesterol checked after the pregnancy, so we set out to evaluate whether Ontarians were getting these tests done.”
Researchers from ICES and Sunnybrook Health Sciences Centre studied over a million pregnant individuals in Ontario, Canada, between 2002 and 2019. They compared screening for diabetes and dyslipidemia in the first three years after delivery between those who developed pregnancy-related hypertension or diabetes (exposed group) and those who did not (unexposed group).
Key Findings
Fewer than 1 in 5 individuals (17%) diagnosed with gestational diabetes or hypertension were screened in the year following pregnancy.
Less than half (44%) of individuals received these tests within three years. Rates for screening for high cholesterol were lower than screening for diabetes.
Surprisingly, 33% of pregnant individuals without gestational diabetes or hypertension received these screening tests.
Given that the gap in screening was more prominent for lipids than diabetes, the authors suggest that access to physicians for cardiovascular preventive care may not be the main cause of these lower screening rates. There may instead be a need for increased awareness of pregnancy-related cardiovascular disease risks among physicians and patients.
"Women should be aware of their risk for cardiovascular disease, so that they can ask their doctors about risk factor screening,” says Dr. Yu, who is also an Associate Professor in Temerty Faculty of Medicine's Department of Medicine at the University of Toronto. “Having this knowledge can also support patients’ decision-making about lifestyle changes, which could improve their vascular health.”

Study reveals surge in gambling addiction following legalization of sports betting
2025-02-17
A new study, published in JAMA Internal Medicine and led by researchers from the University of California San Diego Qualcomm Institute and School of Medicine, reveals a dramatic increase in sports betting and gambling addiction help-seeking since the landmark Murphy v. NCAA Supreme Court decision in 2018 paved the way for states to legalize sports betting.
“When the Supreme Court legalized sportsbooks — a venue where people can wager on various sports competitions — in Murphy v. NCAA, public health experts paid little attention,” said the study’s senior author John W. Ayers, Ph.D., who is vice chief of innovation in the ...
AI screening for heart failure clinical trial speeds up enrollment, study finds
2025-02-17
Artificial intelligence (AI) can rapidly screen patients for clinical trial enrollment, according to a new study published in JAMA and led by Mass General Brigham researchers. Their novel AI-assisted patient screening tool significantly improved the speed of determining eligibility and enrollment in a heart failure clinical trial compared to manual screening. These findings suggest that using AI can be cheaper than conventional methods and speed up the research process, which could mean patients get earlier access to proven, effective treatments.
“Seeing this AI capability accelerate screening and trial enrollment ...
Accelerated drug-testing platform for ALS paves way for therapeutic innovation
2025-02-17
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with few treatment options. Since 2018, the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham healthcare system, has been working with national and international stakeholders to accelerate ALS research by launching the first platform trial in ALS to simultaneously test multiple drugs using shared trial infrastructure and placebo data. Findings from the first four drugs evaluated through the trial are published ...
Pancreatic cancer: blocked nerves as a possible new treatment strategy
2025-02-17
Pancreatic cancer is fueled by connections to the nervous system. This is reported by scientists from the German Cancer Research Center (DKFZ) and the Heidelberg Institute for Stem Cell Technology and Experimental Medicine (HI-STEM)* in their current publication in Nature. The team discovered that the tumor specifically reprograms the neurons for its own benefit. In mice, blocking nerve function inhibited cancer growth and increased the sensitivity of tumor cells to certain chemotherapies and immunotherapies.
For several years, ...
This research is absolutely nuts – for better health care
2025-02-17
A nut used in herbal tea has become a hydrogel perfect for a variety of biomedical uses in new research from the University of Chicago Pritzker School of Engineering (UChicago PME) and UChicago Chemistry Department.
A paper published today in Matter created a malva nut hydrogel for medical uses ranging from wound care to ECG readings. The research doesn’t rely on the rumored health benefits of the nuts – in China, they’re known as the sore throat remedy Pangdahai (PDH) – but for their ability to swell in water.
“You never saw the fruit from a tree expand in that kind of volume,” said first ...
Genetic study links defects in sugar digestion to irritable bowel syndrome
2025-02-17
Sucrase-isomaltase (SI) is an intestinal enzyme critical for the digestion of dietary carbohydrates, particularly sucrose and starch. Previous studies from the Gastrointestinal Genetics team at CIC bioGUNE - BRTA and LUM University suggested a genetic link between SI defects and IBS, whereby certain DNA changes cause reduced enzymatic activity and inefficient digestion of carbohydrates, thus inducing symptoms like bloating, diarrhoea, and abdominal pain. As the name gives away, however, SI is a special case in that it encompasses two enzymes with different carbohydrate-digesting ...

Breaking the pattern: How disorder toughens materials
2025-02-17
Cut open a bone and you’ll see a subtly disordered structure. Tiny beams, called trabeculae, connect to one another in irregular patterns, distributing stress and lending bones an impressive toughness. What if human-made materials could exhibit similar properties?
In a new paper in Proceedings of the National Academy of Sciences Nexus, researchers at Penn Engineering, Penn Arts & Sciences and Aarhus University found that adding just the right amount of disorder to the structure of certain materials can make them more than twice as resistant to cracking.
The finding opens the door to more widespread use of so-called “mechanical metamaterials,” ...
A geometric deep learning method for decoding brain dynamics
2025-02-17
In the parable of the blind men and the elephant, several blind men each describe a different part of an elephant they are touching – a sharp tusk, a flexible trunk, or a broad leg – and disagree about the animal’s true nature. The story illustrates the problem of understanding an unseen, or latent object based on incomplete individual perceptions. Likewise, when researchers study brain dynamics based on recordings of a limited number of neurons, they must infer the latent patterns of brain dynamics that generate these recordings.
“Suppose you and I both engage in a mental task, ...
Novel catalyst development for sustainable ammonia synthesis
2025-02-17
As the world moves toward sustainability, the demand for efficient alternatives across industries continues to grow. Ammonia, a key chemical used in fertilizers, explosives, and various other products, is primarily synthesized through the energy-intensive Haber-Bosch process. This process requires extremely high temperatures and pressures, contributing to global carbon dioxide emissions. Conventional catalysts, such as iron and ruthenium, rely on these harsh conditions to drive the reaction. However, a recent study by researchers from Institute of Science Tokyo, the National Institute for Materials Science, and Tohoku University, Japan, led by Professor Masaaki Kitano, explores ...
