More than half of patients who test positive for tree nut allergies based on blood or skin prick assessments experience no reaction to the nuts when consumed, a new study finds. New research suggests that an oral food challenge should be used to confirm tree nut allergies. Lead study author Dr. Christopher Couch, a...

Researchers find biomarker that could help predict the onset of type 1 diabetes
A significant finding has been made by the 3U Diabetes Consortium, of Dublin City University, Maynooth University and the Royal College of Surgeons in Ireland (RCSI), which has the potential to contribute to the identification of biological markers that predict the development of Type 1 diabetes, a chronic autoimmune disease. The findings, which have been...

Scientists report genetic test to help predict men at most risk from aggressive prostate cancer
Scientists are reporting a test which can predict which patients are most at risk from aggressive prostate cancer, and whether they suffer an increased chance of treatment failure. This test, reported at the European Association of Urology conference in London, and published in the Journal of the National Cancer Institute, may give men a better view...

A new test can detect your blood type with color-changing paper
The paper turns teal or brown, depending on whether the right combination of antigens and antibodies are present. H. Zhang et al, Science Translational Medicine 2017 Knowing a person’s blood type is crucial in medicine. If a traumatic injury leaves you in need of a donor’s blood, an infusion from the wrong blood type can...

Routine blood tests can help measure a patient’s future risk for chronic disease, new study finds
A new study by researchers at the Intermountain Medical Center Heart Institute in Salt Lake City finds that combining information from routine blood tests and age of primary care patients can create a score that measures future risk of chronic disease. This simple risk score, termed the Intermountain Chronic Disease Risk Score, or ICHRON, can...

New approach uses ultrasound to measure fluid in the lungs
A team of engineering and medical researchers has found a way to use ultrasound to monitor fluid levels in the lung, offering a noninvasive way to track progress in treating pulmonary edema — fluid in the lungs — which often occurs in patients with congestive heart failure. The approach, which has been demonstrated in rats,...

The way the brain processes speech could serve as a predictor of early dementia
Early dementia is typically associated with memory and thinking problems; but older adults should also be vigilant about hearing and communication problems, suggest recent findings in a joint Baycrest-University of Memphis study. Within older adults who scored below the normal benchmark on a dementia screening test, but have no noticeable communication problems, scientists have discovered a new potential...
