Nearly a third of breast cancer survivors in Appalachia are not taking the critical, potentially life-saving follow-up treatment - despite having insurance that would pay for it, a troubling new study has found. Researchers cross-examined cancer registries with Medicare claims data and determined that of 428 women, approximately 30 percent failed to follow through with their prescribed adjuvant hormone therapy, a treatment to prevent the cancer's recurrence. "Almost a third of the prescriptions for adjuvant hormone therapy were not filled, which is much, much higher ...

ATLANTA--States' regulations of health insurance and practitioners significantly influence when patients receive colorectal or breast cancer diagnoses, especially among people younger than the Medicare-eligible age of 65, according to a new study by researchers at Georgia State University's School of Public Health and the University of North Carolina at Chapel Hill. The study suggests that where people live is a strong predictor of whether they will receive potentially life-saving cancer screenings. Dr. Lee Rivers Mobley, associate professor of spatial science and health ...

Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-industrial times, the pH of the oceans has dropped from an average of 8.2 to 8.1 today. Projections of climate change estimate that by the year 2100, this number will drop further, to around 7.8 -- significantly lower than any levels seen in open ocean marine communities today. Now a team of researchers from MIT, the University ...

Marine species that already roam far and wide throughout our oceans are extending their territories further and faster in response to climate change, according to new research involving the University of Southampton and an international team of biodiversity experts. The study found that while species that have large ranges are able to make their way to cooler waters, small-ranging species are in increased jeopardy as our planet's oceans continue to warm. "Our findings indicate that animals which already have wide-latitudinal ranges, habitat generalists, and species with ...

New Haven, Conn. -- Researchers at Yale School of Medicine have successfully treated patients with moderate to severe eczema using a rheumatoid arthritis drug recently shown to reverse two other disfiguring skin conditions, vitiligo and alopecia areata. The study is evidence of a potential new era in eczema treatment, they report. The research findings are published early online in the Journal of the American Academy of Dermatology. Eczema (atopic dermatitis) is a chronic condition that causes severe itching and leaves the skin red and thickened. It can adversely affect ...

A slow-down in global warming is not a sign that climate change is ending, but a natural blip in an otherwise long-term upwards trend, research shows. In a detailed study of more than 200 years' worth of temperature data, results backed previous findings that short-term pauses in climate change are simply the result of natural variation. The findings support the likelihood that a current hiatus in the world's year-on-year temperature increases - which have stalled since 1998 - is temporary. Scientists from the University of Edinburgh analysed real-world historic ...

Research findings obtained over the past decades increasingly indicate that stored memories are coded as permanent changes of neuronal communciation and the strength of neuronalinterconnections. The learning process evokes a specific pattern of electrical activity in these cells, which influences the response behavior to incoming signals, the expression of genes and the cellular morphology beyond the learning process itself. "You might say that these changes define the cellular correlate of the memory engram" says Friedrich Johenning, researcher at the Neuroscience Research ...

Researchers from the Institute and Department of Psychiatry, Faculty of Medicine, University of São Paulo, (Brazil); the Imperial College of London, (UK); the University of Western Australia (Australia) and the University of Toronto (Canada) have just published a study in the Journal of Psychopharmacology suggesting that what had been clustered as anxiety disorders is not homogenous in terms of functioning of the serotonergic system. The researchers reanalyzed the results of six other studies that had evaluated the effects of the acute reduction of tryptophan, the ...

Microbial ecosystems such as biological wastewater treatment plants and the human gastrointestinal tract are home to a vast diversity of bacterial species. Scientists of the Luxembourg Centre for Systems Biomedicine (LCSB) and the Life Science Research Unit (LSRU) of the University of Luxembourg, in collaboration with US researchers, have now succeeded for the first time in determining key functional genes and the organisms encoding these in such ecological systems, working from extensive data of bacterial genetics and bacterial metabolism. Keystone species are species ...

The term intellectual disability covers a large number of clinical entities, some with known cause and others of uncertain origin. For example Down syndrome is due to an extra copy of chromosome 21 and Rett syndrome is in part caused by a mutation in the control switch gene called MeCP2. In other cases the mechanisms by which they are produced are not clearly identified. It is the case of most of those disorders classified under the large umbrella of autism. An study published in the journal Genetics in Medicine, by Manel Esteller, director of the Program Epigenetics ...
