Languages affected differently by brain disease

Health
There are differences in the way English and Italian speakers are affected by dementia-related language problems, a small study suggests.While English speakers had trouble pronouncing words, Italian speakers came out with shorter, simpler sentences.The findings could help ensure accurate diagnoses for people from different cultures, the researchers said.Diagnostic criteria are often based on English-speaking patients.In the University of California study of 20 English-speaking patients and 18 Italian-speaking patients, all had primary progressive aphasia - a neuro-degenerative disease which affects areas of the brain linked to language.It is a feature of Alzheimer's disease and other dementia disorders.Brain scans and tests showe...

Technique pioneered to tackle disease threatening half the world

Scientists are working on a pioneering programme aimed at tackling one of the world's most damaging diseases.Dengue fever is a viral infection that can look like severe flu, the symptoms of which include high fever, headache, joint pain and a rash. A 2013 study found that up to 528 million people are infected with dengue fever every year, up to 96 million of which required medical treatment. Image: An aedes aegypti mosquito. Pic: James Gathany/CDC And there is evidence the disease is spreading, with some experts predicting it could be present in western Europe, and even the UK, in the coming decades.At the Institute for Medical Research in the heart of Kuala Lumpur, a team of researchers led by Dr Nazni Wasi Ahmad has scientifically e...
Exposure to bug spray may raise heart disease death risk by 50 percent

Exposure to bug spray may raise heart disease death risk by 50 percent

Health
Dec. 30 (UPI) -- A new analysis has linked environmental exposure to a certain type of insecticides with increased risk for death from heart disease. In findings published Monday in the journal JAMA Internal Medicine, researchers report that higher levels of 3-phenoxybenzoic acid in those exposed to pyrethroid-based sprays and other products likely contributes to a roughly 50 percent increase in their risk for death from cardiovascular disease and/or cancer. Pyrethroids -- which are found in many residential pest control sprays and household and garden insecticides and pet sprays, as well as specialty shampoos, lice treatments and mosquito repellents -- have been used in the United States for more than 40 years. "Pesticide exposure at varying levels is ubiquitous to the general populatio...

Surgeons withdraw support for heart disease advice

Health
European clinical guidelines on how to treat a major form of heart disease are under review following a BBC Newsnight investigation.Europe's professional body for heart surgeons has withdrawn support for the guidelines, saying it was "a matter of serious concern" that some patients may have had the wrong advice.Guidelines recommended both stents and heart surgery for low-risk patients.But trial data leaked to Newsnight raises doubts about this conclusion.Thousands of people in the UK and hundreds of thousands worldwide will be treated for left main coronary artery disease each year. This is a narrowing of one of the main arteries in the heart. The guidelines on how to treat it were largely based on a three-year trial to compare whether heart surgery or st...
Northwestern unveils potential celiac disease treatment

Northwestern unveils potential celiac disease treatment

Health
Oct. 22 (UPI) -- Northwestern Medicine has developed a technology that reduces intolerance to gluten, the new phase 2 clinical trial results show, the university said in a statement on Tuesday. Celiac disease patients in a phase 2 clinical trial were able to eat gluten with substantially less inflammation after the treatment with the technology. Celiac disease is a serious autoimmune disease and digestive disorder where people cannot tolerate gluten in wheat, barley, and rye without damaging the small intestine. The technology consists of a nanoparticle with gluten that "acts like a Trojan horse, hiding the allergen in a friendly shell, to convince the immune system not to attack it," the statement said. The findings were presented Tuesday at the European Gastroenterology Week conferenc...
