ECG scans predict kidney disease patients' risk of dying from heart disease
Routine scans could help clinicians protect patients' heart health

Certain electrocardiogram measures helped investigators identify a subgroup of individuals with chronic kidney disease who had substantially elevated risks of dying from heart disease.
An estimated 26 million people in the United States have chronic kidney disease, and heart disease is the leading cause of death in these patients.
Washington, DC (July 9, 2015) -- Several common measures obtained from electrocardiograms (ECGs) may help clinicians determine a kidney disease patient's risk of dying from heart disease. The findings, which are published in a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN), may be important for preserving kidney patients' heart health.
ECG screening is not recommended for routinely assessing heart health in low-risk populations such as young athletes; however, would ECGs be useful in a higher-risk population such as those with chronic kidney disease (CKD), whose leading cause of death is heart disease?
To investigate, Rajat Deo, MD, MTR (Perelman School of Medicine at the University of Pennsylvania) and his colleagues evaluated whether a panel of 5 common ECG parameters could enhance prediction of CKD patients' risk of dying over a median follow-up of 7.5 years.
Among 3587 patients in the study, 750 participants died. The researchers found that common ECG measures (PR interval, QRS duration, corrected QT interval, heart rate, and left ventricular hypertrophy) identified individuals with CKD who were at an especially high risk of dying from heart disease. "By enhancing the prediction of cardiovascular death in this population, we may find more effective and novel interventions to prevent the complications of cardiovascular disease," said Dr. Deo.
Additional research is needed to evaluate whether treating patients who are found to be at especially high risk due to ECG screening will help to improve and prolong the lives of individuals with CKD.

DALLAS, July 9, 2015 -- Uric acid - a chemical at high levels can lead to serious illness - may lessen women's disability after stroke, according to new research in the American Heart Association's journal Stroke.
High levels of uric acid can lead to kidney stones or the inflammatory arthritic condition known as gout and is linked with heart and vascular problems and diabetes. However, in a new study, 42 percent of women treated with uric acid therapy following a stroke had little to no disability after 90 days compared to 29 percent of women treated with a placebo. Women ...

When past temperatures were similar to or slightly higher than the present global average, sea levels rose at least 20 feet, suggesting a similar outcome could be in store if current climate trends continue.
Findings published in the journal Science showed that the seas rose in response to melting ice sheets in Greenland and Antarctica, said lead author Andrea Dutton, a University of Florida geochemist.
"This evidence leads us to conclude that the polar ice sheets are out of equilibrium with the present climate," she said.

Philadelphia, PA, July 9, 2015 - Researchers at Virginia Tech have developed a new scoring method for assessing beverage intake, the Healthy Beverage Index (HBI). In a report published in the Journal of the Academy of Nutrition and Dietetics they describe how this tool can be used to more accurately evaluate dietary consumption of all types of fluids. They found that higher HBI scores were associated with more favorable lipid profiles, decreased risk of hypertension; and, among men, better C-reactive protein (CRP) levels.
Water consumption is associated with numerous ...

Natural environments are known to promote physical, mental, and spiritual healing. People can attain health benefits by spending time outside, often in remote places to "get away from it all." Now research conducted by a University of Minnesota graduate student with a team in Vancouver, B.C., shows that green and "blue" spaces (environments with running or still water) are especially beneficial for healthy aging in seniors.
Published in the journal Health and Place, the study -Therapeutic landscapes and wellbeing in later life: Impacts of blue and green spaces for older ...

Two of NASA's heliophysics missions can now claim planetary science on their list of scientific findings. A group of scientists used the Venus transit - a very rare event where a planet passes between Earth and the sun, appearing to us as a dark dot steadily making its way across the sun's bright face - to make measurements of how the Venusian atmosphere absorbs different kinds of light. This, in turn, gives scientists clues to exactly what elements are layered above Venus's surface. Gathering such information not only teaches us more about this planet so close to our own, ...

NASA's Aqua satellite passed over Supertyphoon Nangka on July 9 and provided a visible and an infrared view of the large storm.
At 0700 UTC (3 a.m. EDT) on July 9 a typhoon warning was in effect for Agrihan, Pagan and Alamagan in the northern Marianas. A tropical storm warning is in effect for Saipan and Tinian. Nangka passed over Alamagan.
The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite gathered infrared temperature data on Nangka on July 9 at 03:23 UTC (July 8 at 11:23 a.m. EDT). At the same time, the MODIS instrument took a visible ...

Studying the gastric cancers of 15 Southeast Asian patients, researchers at The Jackson Laboratory, the Genome Institute of Singapore and other institutions identified five recurrent fusion genes, one of which appears to lead to cellular changes involved in acute gastritis and cancer.
Worldwide, close to a million cases of gastric cancers are diagnosed each year, and some of the world's highest incidence rates are in Asia (particularly in Korea, Japan and China).
The researchers, led by JAX Professor Yijun Ruan, Ph.D., and Axel M. Hillmer, Ph.D., of GIS, published ...

LOS ANGELES (July 9, 2015) - After generating new brain tumor models, Cedars-Sinai scientists in the Board of Governors Regenerative Medicine Institute identified the role of a family of genes underlying tumor growth in a wide spectrum of high grade brain tumors.
"With these new genetic findings, our group of researchers plan to develop targeted therapeutics that we hope will one day be used treat patients with high grade brain tumors and increase their survival," said Joshua Breunig, PhD, a research scientist in the Brain Program at the Cedars-Sinai Board of Governors ...

Tropical Storm Ela was born in the western-most part of the Eastern Pacific Ocean but has become the Central Pacific's first named storm. NASA's Aqua satellite took a look at the storm that's already battling wind shear to survive.
After developing as a depression on July 8, Tropical Depression 4E crossed over the 140 degree West longitude line that separates the Eastern Pacific from the Central Pacific Ocean region. The depression strengthened into a tropical storm early on July 9, taking a name from the Eastern Pacific tropical cyclone list and being renamed Ela.
