(Press-News.org) Children lose muscle during early cancer treatment — new ECU study warns of a hidden danger to recovery
New research from the Exercise Medicine Research Institute at Edith Cowan University (ECU) has highlighted that children undergoing cancer treatment often lose skeletal muscle at a time when they should be rapidly gaining it, a loss that could increase treatment complications and raise the risk of long-term health problems.
“Both the cancer itself and the cancer treatment can cause muscle loss in children,” said ECU PhD student Anna Maria Markarian.
“Muscle is the body’s metabolic reserve. When children lose muscle during treatment, they tolerate chemotherapy less well and face a higher risk of complications from drug toxicity.”
Losing muscle also makes children and adolescents more vulnerable to heart and metabolic problems such as high blood sugar and insulin resistance, Ms Markarian said.
“For example, during the onset of puberty children gain 3 kg to 5 kg of muscle per year. If treatment interrupts this growth and it isn’t recovered afterwards, it can severely impact health outcomes in the longer term.”
The research also found that children undergoing cancer treatment are likely to experience increases in fat mass, which can further contribute to metabolic problems and increase the risk of heart-related issues.
“Weight is not the whole story. Two kids can weigh the same, one with healthy muscle, one with excess fat, and their ability to tolerate chemotherapy could be very different.
“The challenge here is differentiating between muscle loss and fat gain, as this could have important clinical implications. Shifts in body composition can create a mismatch between dosing assumptions and actual metabolic capacity, heightening the risk of treatment-related complications and poorer clinical outcomes in patients with diminished skeletal muscle mass,” Ms Markarian said.
The message for parents is simple: keep kids moving. Encourage age-appropriate active play and exercise, despite the obvious difficulties that would be associated with that.

World-first koala chlamydia vaccine approved
In a world first, a vaccine has been approved to protect Australia’s endangered koalas from infection and death caused by chlamydia.
Developed by the University of the Sunshine Coast, the vaccine’s approval by Australia’s veterinary medicine regulator is a major step in the fight against one of the greatest threats to the long-term survival of the nation’s iconic marsupial.
Led by Professor of Microbiology Peter Timms, University of the Sunshine Coast researchers have spent more than 10 years developing the vaccine to protect ...
Taking the pulse of digital health in Asia
2025-09-10
HONG KONG (9 September 2025)—Advancing digital healthcare innovation across the region is the key driver behind Digital Health Asia 2025, organised by Times Higher Education (THE) in partnership with City University of Hong Kong (CityUHK) and the Institute of Digital Medicine (IDM).
Digital Health Asia, from 8 to 10 September, has brought together over 420 delegates from 17 regions, including leaders from academia, healthcare, government, and industry, to foster collaboration and drive progress in digital health.
“Digital Health Asia 2025 is more than just a conference. It is a celebration of the spirit of collaboration,” ...
Even healthy children can be severely affected by RSV
2025-09-10
It is not only premature babies and children with underlying diseases who suffer from serious respiratory syncytial virus (RSV) infections. Even healthy, full-term babies are at significant risk of intensive care or prolonged hospitalisation – especially during the first three months of life. This is according to a comprehensive registry study from Karolinska Institutet in Sweden published in The Lancet Regional Health – Europe.
RSV is a common cause of respiratory infections in young children and accounts for around 245,000 ...
Keto diet linked to reduced depression symptoms in college students
2025-09-10
[Embargoed until 8 p.m. ET Sept. 9, 2025 (1 a.m. UK Sept. 10, 2025), coinciding with publication in Translational Psychiatry]
COLUMBUS, Ohio – A new study shows an association between at least 10 weeks of following a well-formulated ketogenic diet and a roughly 70% decrease in depression symptoms among a small group of college students.
Beyond the reduction in self-reported and clinician rated depression, the students’ global well-being increased nearly three-fold and their performance improved on several cognitive tasks. All but one participant ...
Blood test identifies HPV-associated head and neck cancers up to 10 years before symptoms
2025-09-10
Human papilloma virus (HPV) causes around 70% of head and neck cancers in the United States, making it the most common cancer caused by the virus, with rates increasing each year. Unlike cervical cancers caused by HPV, there is no screening test for HPV-associated head and neck cancers. This means that patients are usually diagnosed after a tumor has grown to billions of cells in size, causing symptoms and spreading to lymph nodes. Screening methods that can detect these cancers much earlier could mean earlier treatment interventions for patients.
In a new federally funded study, published in the Journal of the National Cancer Institute, Mass General Brigham researchers ...
Odds of dementia strongly linked to number of co-existing mental health disorders
2025-09-09
The odds of developing dementia are strongly linked to the number of co-existing mental health disorders, rising from twice as high for one disorder to 11 times as high for four or more, finds research published in the open access journal BMJ Mental Health.
In particular, the combination of concurrent mood and anxiety disorders is linked to odds of dementia of up to 90%, the findings indicate.
Psychiatric disorders, such as depression, anxiety, and bipolar disorder, have been individually associated with an increased risk ...
Large social and economic inequalities persist among UK doctors
2025-09-09
Large social and economic inequalities persist among UK doctors, with those from a professional background 6 times more likely to become a medical practitioner than those from a working class background, reveals a 10 year study, published in the open access journal BMJ Open.
Greater efforts are needed to boost the social mobility of medical school applicants and better understand the effects of these inequalities on patient care, say the researchers.
National data from 2014 show that only 4% of practising doctors came from lower-income working class backgrounds. And despite concerted efforts over the past 20 years to ...
Research reveals how microplastics threaten Gulf of Mexico marine life
2025-09-09
Critical wildlife habitats are exposed to pollution risk in the seas off the southern United States, with implications for human health and food security. “Most of the pollution comes from rivers and not from wastewater treatment plants,” says CMCC scientist Annalisa Bracco, co-author of the study that used advanced computer models to track tiny plastic particles across three years.
The Gulf of Mexico is facing a growing threat from microplastic pollution, with new research revealing how tiny plastic particles are accumulating in areas crucial to marine life including sea turtles, red snapper, and dolphins. A comprehensive study ...
AI tool developed at Oxford helps astronomers find supernovae in a sky full of noise
2025-09-09
A new AI-powered tool has reduced astronomers’ workload by 85% - filtering through thousands of data alerts to identify the few genuine signals caused by supernovae (powerful explosions from dying stars). The findings have been published today (10 Sept) in The Astrophysical Journal.
Lead researcher Dr Héloïse Stevance (Department of Physics, University of Oxford) said: “The surprising thing is how little data it took. With just 15,000 examples and the computing power of my laptop, I could train smart algorithms to do the heavy lifting and automate what used to take a human beings hours to do each day. This demonstrates that ...
Hungry star is eating its cosmic twin at rate never seen before
2025-09-09
A greedy white dwarf star not far from Earth is devouring its closest celestial companion at a rate never seen before, space scientists have discovered.
Their study found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy.
Experts think the stars are locked in an extraterrestrial tango as they orbit each other every 12.3 hours, gradually pulling each other closer.
They say it could cause a massive explosion so bright it would be seen by the naked eye from Earth, some 10,000 lightyears away.
The findings were made by an international team of astronomers involving Professor Phil Charles from University ...
