(Press-News.org) New research published in BJOG: An International Journal of Obstetrics & Gynaecology found that mothers who are anemic in early pregnancy face a higher likelihood of giving birth to a child with a heart defect.
The study assessed the health records of 2,776 women with a child diagnosed with congenital heart disease who were matched to 13,880 women whose children did not have this condition.
Investigators found that 4.4% of children with congenital heart disease and 2.8% of children with normal heart function had anemia. After adjusting for potential influencing factors, the odds of giving birth to a child with congenital heart disease was 47% higher among anemic mothers.
“We already know that the risk of congenital heart disease can be raised by a variety of factors, but these results develop our understanding of anemia specifically and take it from lab studies to the clinic. Knowing that early maternal anemia is so damaging could be a gamechanger worldwide,” said corresponding author Duncan B. Sparrow, PhD, of the University of Oxford. “Because iron deficiency is the root cause of many cases of anemia, widespread iron supplementation for women—both when trying for a baby and when pregnant—could help prevent congenital heart disease in many newborns before it has developed.”

How does climate policy uncertainty affect energy stock returns?
2025-04-23
The back-and-forth shift in climate policy between the Biden and Trump administrations has created uncertainty about future directions related to addressing climate change. A new study in International Studies of Economics examined the impact of climate policy uncertainty on world energy stock returns.
The study found that a rise in climate policy uncertainty causes stocks to plummet in individual countries, regions, and the world energy stock markets, as investors perceive that climate policy uncertainty could ...
World on course to trigger multiple climate ‘tipping points’ unless action accelerates
2025-04-23
Multiple climate “tipping points” are likely to be triggered if global policies stay on their current course, new research shows.
Scientists assessed the risk of “tipping” in 16 different parts of the Earth system – ranging from the collapse of major ice sheets to the dieback of tropical coral reefs and vast forests.
Based on current policies and the resulting global warming, their most conservative estimate is a 62% risk of triggering these tipping points on average.
However, more sustainable future pathways – with lower greenhouse gas emissions – significantly ...
Research on genetic differences in men's and women's health awarded
2025-04-23
Colm Nestor, senior associate professor in medical genetics, has been awarded the 2025 Onkel Adam Prize for outstanding research at the Faculty of Medicine and Health Sciences at Linköping University, Sweden. One of his research areas is gender differences in susceptibility to autoimmune diseases and infections.
Having studied both plant biology and programming, Colm Nestor happened to have the right skills at the right time. He had just finished his undergraduate programme at the turn of the millennium when the human genome was mapped through ...
Police officers fire more shots than civilians in homicides, research shows
2025-04-23
Ann Arbor, April 23, 2025 - An analysis using data from the US National Violent Death Reporting System (NVDRS) has found that in homicides with police shooters, victims have been shot far more times than in homicides with civilians as shooters. The new study, appearing in the American Journal of Preventive Medicine, published by Elsevier, showed that individuals aged 25 to 44, Black people, and those living outside the Northeast region of the US tend to be disproportionately killed by police as well as sustain a higher number of bullet wounds.

People turn to conspiracy theories in a subconscious quest to feel like they ‘matter’, research suggests
2025-04-23
While all people are innately driven to find meaning in their lives, this subconscious desire pulls some people to conspiracy theories and dangerous belief systems.
After an extensive review of psychological research, renowned social psychologist Arie Kruglanski and journalist Dan Raviv show how people’s need for ‘significance’ propels our actions, governs our feelings, and dominates our thoughts in their new book The Quest for Significance.
“Experts on human motivation contend that all people share the same set of basic needs, and everything people do, try to attain, or avoid is in the service of satisfying one or more of those basic needs,” ...

Crystal clear design for high-performance flexible thermoelectric semiconductor
2025-04-23
QUT researchers have identified a new material which could be used as a flexible semiconductor in wearable devices by using a technique that focuses on the manipulation of spaces between atoms in crystals.
In a study published in the prestigious journal Nature Communication (http://doi.org/10.1038/s41467-025-58104-x), the researchers used “vacancy engineering” to enhance the ability of an AgCu(Te, Se, S) semiconductor, which is an alloy made up of silver, copper, tellurium, selenium and sulphur, to convert body ...
Detecting lung cancer 4 months earlier at the GP using artificial intelligence
2025-04-22
GPs may soon be able to identify patients with an increased risk of lung cancer up to 4 months earlier than is currently the case. The GP should be able to simply identify patients during a consultation with an algorithm created by researchers at Amsterdam UMC based on the data of more than half a million patients. The results of the study were published today in the British Journal of General Practice. [doi-link: https://doi.org/10.3399/BJGP.2023.0489]
The algorithm looks at all medical information from general ...
Safer opioid supply improves health outcomes among people at high risk of overdose
2025-04-22
Toronto, ON, April 22, 2025 – Research from ICES and Unity Health Toronto shows that safer opioid supply programs and methadone both reduce opioid overdoses, healthcare utilization, and costs.
Safer opioid supply (SOS) programs provide pharmaceutical-grade opioids such as hydromorphone to people struggling with opioid use disorder. Prescribed opioid medications are a safer alternative to drugs found in the unregulated drug supply due to the potency and unpredictability of that supply.
“This is the first population-based study to compare SOS programs with opioid agonist treatment, and to explore ...
