Rate of severe reactions higher than thought in young children with food allergies

A recent study by the Consortium of Food Allergy Research (CoFAR) found that young children with milk and egg allergies experience severe reactions at a higher rate than previously believed. The study also revealed that some caregivers are hesitant to give epinephrine, a medication that reverses the symptoms of such reactions. Nearly 1...

Study identifies causes for high rates of allergic reactions in children with food allergies

A recent study found that young children with food allergies experience almost one allergic reaction per year, despite parental instructions on food avoidance. The study highlights the importance of educating parents and caregivers about avoiding allergenic foods and using epinephrine to treat severe reactions.

New tools for evaluating quality of life for cats, dogs with heart disease

Researchers at Tufts University have developed two surveys, FETCH and CATCH, to evaluate the quality of life for dogs and cats with heart disease. The tools ask owners to rank aspects of their pet's health on a scale of 0-5, allowing veterinarians to assess the animal's perceived quality of life.

The skinny on what makes us fat

Research found that SFRP5-deficient mice showed increased metabolic activity and were resistant to diet-induced obesity, revealing the mechanism of SFRP5-mediated fat cell generation. The study suggests targeting the WNT signaling pathway could be a therapeutic approach to treat obesity.

Biological switch paves way for improved biofuel production

Researchers from Queen Mary University of London have identified a biological mechanism controlling electron transport in cyanobacteria, which could lead to more efficient solar-powered biofuel production. The discovery was made by exposing cells to different light conditions and observing the changes in electron transport pathways.

UCLA biologists reveal potential 'fatal flaw' in iconic sexual selection study

A classic study on male and female promiscuity has been called into question after UCLA biologists repeated the experiment using the same methods as the original. The team found that Bateman's conclusions about the relationship between mate number and offspring fitness were likely flawed due to a bias in his methodology.

Vitamin D tests are inaccurate

A study by Loyola University Chicago Stritch School of Medicine found that two new vitamin D test kits had poor performance, with results deviating from the gold standard method by up to 25%. This inaccuracy could lead to misdiagnoses and overtreatment of vitamin D deficiency.

Stillbirth rate twice as high among least well off in England

Research published in BMJ Open finds that stillbirth rates are twice as high among the least well-off in England, with the gap remaining constant over eight years. Socio-economic inequalities in stillbirths by cause have been evident across all causes, including bleeding before birth and congenital abnormalities.

Prions and cancer: A story unfolding

A recent study published in the Journal of Biological Chemistry reveals that mutant p53 protein aggregates may lead to prion-like behavior, impairing its ability to suppress tumor growth. The findings suggest that this misfolding mechanism could serve as a potential target for cancer therapy.

Mount Sinai researcher finds timing of ADHD medication affect academic progress

A study by Mount Sinai researchers found that the timing of ADHD medication impact on children's performance on standardized tests. The findings showed that starting medication within 12 months after fourth-grade test led to a decline of 0.3 percent in math compared to 9.4 percent for those who started treatment later.

Swine flu vaccination program a success in Scotland

A successful swine flu vaccination program in Scotland showed 77% protection against the H1N1 virus, while also reducing hospital admissions by 20% due to related disorders. The program's effectiveness was demonstrated through detailed data analysis, which took into account multiple conditions such as pneumonia and COPD.
