Consumption of dietary supplements sold for weight loss, muscle building, and energy was associated with increased risk for severe medical events in children and young adults compared to consumption of vitamins, according to new research led by Harvard T.H. Chan School of Public Health. The study found that, compared with vitamins, these types of supplements
In ongoing research to find a treatment for acute kidney injury, Wake Forest Institute for Regenerative Medicine (WFIRM) scientists have further advanced a promising approach using therapeutic factors produced by stem cells by creating a more efficient delivery method that would improve tissue regeneration. WFIRM researchers wanted to determine if any of the growth factors
An anterior cruciate ligament (ACL) tear, an injury of the knee, can be devastating to a young athlete. While the ACL can be reconstructed through surgery, there is a high risk of re-injury in patients under the age of 25. In the largest clinical trial of its kind, researchers at Lawson Health Research Institute have
University of Sydney research provides new evidence that nanoparticles, which are present in many food items, may have a substantial and harmful influence on human health. The study investigated the health impacts of food additive E171 (titanium dioxide nanoparticles) which is commonly used in high quantities in foods and some medicines as a whitening agent.
Substituting fishmeal in aquaculture feeds with plant ingredients may not be as beneficial for the environment as many predict, according to new research from an international team of experts. Manufacturers of commercial fish feed are increasingly substituting fishmeal — a powder made from fish — with crop-based ingredients in a move driven by economic incentives
What makes a biological clock tick? According to a new study from U of T Mississauga, the surprising answer lies with a gene typically associated with stem and cancer cells. In the first study of its kind for the field of circadian biology, UTM researchers used RNA sequencing to observe the expression of genes in
Racial and ethnic disparities in severe maternal morbidity — life-threatening maternal complications associated with childbirth — have persisted and increased at high rates among U.S. women, according to an analysis of nearly 20 years of California hospital records funded by the National Institutes of Health. Known risk factors for these complications — such as blood
A research group headed by Professor Outi Mäkitie, University of Helsinki, Finland, identified in families with childhood-onset osteoporosis disease-causing mutations in a gene that had previously not been connected with the skeletal system or osteoporosis. “Through extensive genetic research, we identified a gene defect underlying osteoporosis in two Finnish families with several affected family members.
If hospital doctors around the world often struggle to become those health centaurs, half professionals and half managers, that modern healthcare organizations need, the main responsibility is not their resistance to change, but the lack of effective support from the organization, according to a study by Marco Sartirana (CERGAS, Bocconi University), Graeme Currie (Warwick Business
The complex sugars found in human breastmilk, long believed to be fixed in their composition, may change in women who are taking probiotics, according to new research from the University of Rochester Medical Center (URMC). The finding, published in a research letter in JAMA Pediatrics, upends what scientists thought of human milk oligosaccharides (HMOs) —
Myths about gluten are hard to bust. Intolerance, allergy, sensitivity, hypersensitivity. What is what? Celiac disease is none of these things. It is an autoimmune disorder, where gluten triggers the immune system to attack the gut. It is common, lifelong, and can seriously harm health — but nobody knows for sure what causes it. Now
Scientists at the University of Birmingham have developed a novel eye drop that rapidly reduces sight-threatening scarring to the surface of the eye. The surface of the eye (the cornea) is usually transparent, but scars resulting from eye infection or trauma make it opaque causing blurred vision or in extreme cases complete blindness. Their pre-clinical
Medical researchers at Melbourne’s Murdoch Children’s Research Institute have made a new discovery about how a baby’s sex is determined — it’s not just about the X-Y chromosomes, but involves a ‘regulator’ that increases or decreases the activity of genes which decide if we become male or female. The study, ‘Human Sex Reversal is caused
Argonne researchers have demonstrated a new technique’s viability for membranes. Whether it’s tap water or a cup of coffee, almost everything we drink passes through some kind of filter. The ability to transform liquids this way is essential to daily life, yet it often rests on relatively delicate membranes that can quickly clog or degrade.
Researchers at The University of Texas at Arlington have found a potential new pathway to regulate immune response and potentially control inflammatory diseases of the central nervous system such as meningitis and sepsis. “We need to know what turns on inflammatory response to bacterial infection to be able to modulate the process,” said Subhrangsu Mandal,
Group A Streptococcus (GAS), sometimes known as “flesh-eating bacteria,” causes invasive infections that result in high mortality. GAS is susceptible to many antibiotics, but continues to cause devastating infections. Many studies have attempted to understand the mechanism for immune recognition of GAS; none has provided a clear explanation, until now. In a new study published
The CRISPR genome editing technique promises to be a “transformative leap” in genetic engineering and therapy, affecting almost every area of medicine. That includes plastic surgery, with potential advances ranging from prevention of craniofacial malformations, to therapeutic skin grafts, to new types of rejection-free transplants, according to a paper in the November issue of Plastic
By incorporating a gene-suppressing drug into an over-the-counter gel, researchers at Albert Einstein College of Medicine and their colleagues cut healing time by half and significantly improved healing outcomes compared to control treatments. Results from the combination therapy, which was tested in mice, were published online today in Advances in Wound Care. “Not only did
A University of Adelaide forensic pathologist is warning that potentially harmful substances found in herbal medicines may be playing a bigger role in deaths of ‘health tourists’ than previously thought. Professor Roger Byard is calling for closer checks during post-mortems for the presence of drugs and adulterants that originate from herbal remedies. “There is a
Currently, the medicinal use of cannabinoids, extracted from cannabis, is a subject of debate around the world. In Switzerland, more and more people are advocating for increased research into cannabis. Today, tetrahydrocannabinol (THC) is used in the medical field to deal with certain types of pain, muscle cramps, dizziness and loss of appetite. However, it
