Epigenetic changes in children with Crohn’s disease seen in study

Epigenetic changes in children with Crohn’s disease seen in study

A new study finds a wide range of epigenetic changes — alterations in DNA across the genome that may be related to key environmental exposures — in children with Crohn’s disease (CD), reports Inflammatory Bowel Diseases , official journal of the Crohn’s & Colitis Foundation of America (CCFA). The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Continue reading

Home-based primary care lowers medicare costs for high-risk elders, data shows

MedStar Washington Hospital Center geriatricians found that when medical care for frail elders with advanced illness shifts to the home, total Medicare costs were reduced by 17 percent during a two-year period. Continue reading

Home-based primary care lowers medicare costs for high-risk elders, data shows

MedStar Washington Hospital Center geriatricians found that when medical care for frail elders with advanced illness shifts to the home, total Medicare costs were reduced by 17 percent during a two-year period. A new study published in the Journal of American Geriatrics Society (JAGS) underscores the value of home-based primary care for America’s aging seniors Continue reading

Noninvasive advanced image analysis could lead to better patient care

Noninvasive advanced image analysis could lead to better patient care

Lung cancer patients could receive more precise treatment, and their progress could be better tracked, using a new high-tech method of non-invasive medical imaging analysis, according to a study published by the journal PLOS ONE . Genetic changes increasingly are recognized as driving cancer development. But obtaining evidence of these changes usually requires a biopsy, which can be problematic for sensitive regions of the body such as the lungs. Continue reading

Coordinated intervention reduced prevalence of drug-resistant CRE in long-term care

Coordinated intervention reduced prevalence of drug-resistant CRE in long-term care

A new study found a nationwide effort to control carbapenem-resistant Enterobacteriaceae (CRE) in Israel reduced CRE cases by improving compliance of infection control standards and using a coordinated intervention focused on long-term care facilities. Continue reading

More than 10 percent of heart attack patients may have undiagnosed diabetes

More than 10 percent of heart attack patients may have undiagnosed diabetes

At least 10 percent of people who have a heart attack may have undiagnosed diabetes, according to new research presented at the American Heart Association’s Quality of Care and Outcomes Research Scientific Sessions 2014. Researchers studied data on 2,854 heart attack patients who did not have a known diagnosis of diabetes in 24 U.S. hospitals to understand the prevalence and recognition of undiagnosed diabetes.

How infants understand speech: New study sheds light

A new study from a UT Dallas researcher demonstrates the importance of considering developmental differences when creating programs for cochlear implants in infants. Dr. Andrea Warner-Czyz, assistant professor in the School of Behavioral and Brain Sciences, recently published the research in the Journal of the Acoustical Society of America . Continue reading

Intersection of aging, chronic disease studied

A new collection of articles appearing in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences focuses on how the basic biology of aging drives chronic disease. Continue reading

Statistical test increases power of genetic studies of complex disease

Statistical test increases power of genetic studies of complex disease

The power of genome-wide association studies (GWAS) to detect genetic influences on human disease can be substantially increased using a statistical testing framework reported in the May issue of the journal GENETICS . Despite the proliferation of GWAS, the associations found so far have largely failed to account for the known effects of genes on complex disease — the problem of “missing heritability.” Standard approaches also struggle to find combinations of multiple genes that affect disease risk in complex ways (known as genetic interactions). The new framework enhances the ability to detect genetic associations and interactions by taking advantage of data from other genomic studies of the same population. Continue reading
