OAK BROOK, Ill. – Whole-body MRI may serve as a valuable noninvasive tool for assessing the risk of heart attack and stroke in diabetic patients, according to a new study published online in the journal Radiology. Diabetes is a metabolic disease characterized by an increased concentration of glucose in the blood. There are 347 million diabetic patients worldwide, and the World Health Organization projects that diabetes will be the seventh leading cause of death by 2030. Patients with diabetes are known to develop atherosclerosis, or thickening of the arterial walls, ...

OAK BROOK, Ill. – A team of California-based breast imagers and breast cancer risk specialists have developed a website to help navigate the new challenges posed by breast density notification laws, according to a special report published online in the journal Radiology. While mammography is considered the best single modality for population-based screening, its sensitivity is diminished by up to 20 percent in patients with dense breasts (breasts with a higher ratio of fibroglandular tissue to fat). This reduction in sensitivity is due for the most part to masking, a ...

COLUMBUS, Ohio – Adding a mental health component to school-based lifestyle programs for teens could be key to lowering obesity, improving grades, alleviating severe depression and reducing substance use, a new study suggests. As a group, high-school students who participated in an intervention that emphasized cognitive behavioral skills building in addition to nutrition and physical activity had a lower average body mass index, better social behaviors and higher health class grades and drank less alcohol than did teenagers in a class with standard health lessons. Symptoms ...

San Diego, CA, September 10, 2013 – New cases of diabetes continue to increase as does the health burden for those with diabetes. Law is a critical tool for health improvement, yet assessments reported in a new study published in the American Journal of Preventive Medicine indicate that federal, state, and local laws give only partial support to guidelines and evidence-based interventions relevant to diabetes prevention and control. The authors explore the role that law can play in serving as an effective health tool. In 2010, diabetes was the seventh-leading cause of ...

Philadelphia, PA, September 10, 2013 – A new study has found that a novel avian-origin H7N9 influenza A virus, which has recently emerged in humans, attaches moderately or abundantly to the epithelium of both the upper and lower respiratory tracts. This pattern has not been observed before for avian influenza A viruses. The report, published in the October issue of The American Journal of Pathology, suggests that the emerging H7N9 virus has the potential to cause a pandemic, since it may transmit efficiently in humans and cause severe pneumonia. The first report of infections ...

Scientists have developed a strain of the Middle East respiratory syndrome coronavirus (MERS-CoV) that could be used as a vaccine against the disease, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology. The mutant MERS virus, rMERS-CoV-ΔE, has a mutation in its envelope protein that makes it capable of infecting a cell and replicating its genetic material, but deprives it of the ability to spread to other tissues and cause disease. The authors say once additional safe guards are engineered into the ...

A Simon Fraser University researcher studying hypertension rates in the U.S., Canada and England says each country needs to do more to prevent the condition, which is the leading risk factor for stroke and heart disease. "These data show that thousands of deaths could be prevented each year by improving blood pressure in Canada and other countries," says SFU Health Sciences professor Michel Joffres, the paper's lead author. "Hypertension is the number-one risk factor for mortality in the world, and small improvements in hypertension show important benefits in mortality, ...

(Santa Barbara, Calif.) — If you've ever wondered how you learn to like a food you dislike, a new study conducted by UC Santa Barbara's Craig Montell, Duggan Professor of Neuroscience in the Department of Molecular, Cellular, and Developmental Biology, may offer an answer. The work addresses a central question in neurobiology — how experience can alter animal behavior. The research, just published in Nature Neuroscience, was conducted by Montell's team, which includes lead author Yali Zhang, Rakesh Raghuwanshi, and Wei Shen. Among the most widely observed, but poorly ...

An international study led by a Johns Hopkins pulmonary expert finds that the drug tiotropium (marketed as the Spiriva brand), can be delivered safely and effectively to people with chronic obstructive pulmonary disease (COPD) in both "mist" and traditional "dry powder" inhalers. The new Respimat inhaler, which delivers the drug in a mist form, is approved for use in Europe but not in the United States. The traditional inhaler, known as a HandiHaler, uses a dry powder form of the drug and is widely used in the U.S. The study comparing the two drug-delivery systems ...

Study identifies fibroblast growth factor 18 as an ovarian cancer biomarker Ovarian cancer is one of the leading causes of cancer-related death in women and is often not detected until the later stages of disease, which contributes to poor prognosis. Biomarkers that can be used for early diagnosis and outcome have been identified; however, many of these have not been evaluated at the biological and clinical levels. In this issue of the Journal of Clinical Investigation, Michael Birrer and colleagues at Massachusetts General Hospital identify fibroblast growth factor ...

Patients with type 2 diabetes have increased levels of circulating glucose and fatty acids, which lead to disease complications. In healthy individuals, β cells within pancreatic islets release insulin in response to glucose and incretins, which are gastrointestinal hormones. Coordination between β cells is predicted to be important for insulin release. In this issue of the Journal of Clinical Investigation, David Hodson and colleagues at Imperial College London demonstrate that β cell-β cell interactions are important for insulin secretion in human ...

(TORONTO, Canada – Sept. 9, 2013) – Clinical researchers at Princess Margaret Cancer Centre have discovered why multiple myeloma, an incurable cancer of the bone marrow, persistently escapes cure by an initially effective treatment that can keep the disease at bay for up to several years. The reason, explains research published online today in Cancer Cell, is intrinsic resistance found in immature progenitor cells that are the root cause of the disease – and relapse – says principal investigator Dr. Rodger Tiedemann, a hematologist specializing in multiple myeloma and ...

Barcelona, Spain: Collecting samples of exhaled breath from people at a high risk of lung cancer could be a cheap and non-invasive method of diagnosing the disease, according to new research. The findings will be presented today (9 September 2013) at the European Respiratory Society (ERS) Annual Congress in Barcelona. Current tests for lung cancer include blood and urine tests, followed by CT scans and chest radiographs. This new method could see people at a high risk of lung cancer receiving an initial breath test to quickly assess their symptoms. Previous research ...

Barcelona, Spain: People with severe asthma, who are often described as 'steroid-dependent', are actually less likely to respond to the treatment they depend on, when compared to people with mild asthma. The study, presented at the European Respiratory Society (ERS) Annual Congress in Barcelona today (9 September 2013), represents the first analysis of a cohort of patients from an unparalleled research project that will collect over 3 million samples from 300 children and 700 adults with severe and non-severe asthma, and without asthma. Although asthma is common, ...
