(Press-News.org) Hip replacement surgery, or total hip arthroplasty (THA), can lessen pain and improve function in individuals with hip osteoarthritis, but some patients continue to experience long-term physical deficits—including muscle weakness, decreased functional mobility, and increased fall risk—after the procedure. New research published in the Journal of Orthopaedic Research reveals that a patient’s muscle quality before THA may predict their risk of such suboptimal recovery after surgery.
In the study, 10 people undergoing THA underwent imaging tests before surgery. Patients whose imaging results indicated poor muscle quality were more likely to perform poorly on movement tasks after surgery, compared with those with good muscle quality. The severity of patients’ osteoarthritis before surgery (as indicated by the imaging tests performed) was not linked to their functional abilities after surgery.
“The findings from this study indicate that hip muscle quality may be an important predictor of post-operative biomechanical recovery following hip replacement. Muscle quality is often overlooked, and magnetic resonance imaging is needed to visualize muscle composition, which is not routinely collected for hip replacement patients,” said corresponding author Jeannie F. Bailey, PhD, of the University of California, San Francisco. “Future studies will seek to understand possible implications for poor hip muscle quality on long-term functional outcomes.”

Do traumatic events predict eating disorders among Palestinians?
2025-04-23
Results from a study published in Brain and Behavior suggest that traumatic events may contribute to the development of eating disorders among Palestinians. Also, certain sociodemographic factors—such as educational level, gender, region, and age—were linked to a greater likelihood of experiencing eating disorders.
In the study of 580 adults, including 320 males and 260 females, who were recruited online, individuals who reported living through traumatic events were more likely to experience restraint eating, eating concern, weight ...
Does anemia during pregnancy affect newborns’ risk of heart defects?
2025-04-23
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.

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 ...

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,” ...
