UNIVERSITY PARK, Pa. -- Asking just two questions may be able to help nurses and doctors quickly and easily identify delirium in hospitalized older adults, according to health researchers. Delirium is a reversible cognitive condition that can be resolved if caught and treated early. "Delirium can be very costly and deadly -- and with high-risk patients, time matters," said Donna M. Fick, Distinguished Professor of Nursing and co-director of the Hartford Center of Geriatric Nursing Excellence at Penn State. "Our ultra-brief two-item bedside test for delirium takes an ...

According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at Boulder showed the annual minimum extent was 1.70 million square miles (4.41 million square kilometers) on Sept. 11. This year's minimum is 699,000 square miles (1.81 million square kilometers) lower than the 1981-2010 average. Arctic sea ice cover, made of frozen seawater that floats on top of the ...

Earth's gravity has influenced the orientation of thousands of faults that form in the lunar surface as the moon shrinks, according to new results from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. In August, 2010, researchers using images from LRO's Narrow Angle Camera (NAC) reported the discovery of 14 cliffs known as "lobate scarps" on the moon's surface, in addition to about 70 previously known from the limited high-resolution Apollo Panoramic Camera photographs. Due largely to their random distribution across the surface, the science team concluded that the ...

People with a genetic predisposition for age-related macular degeneration (AMD) significantly increased their odds of developing the blinding eye disorder if they had a history of heavy smoking and consistently did not exercise or eat enough fruits and vegetables, according to an observational study of women funded by the National Eye Institute, part of the National Institutes of Health. Eating a healthy diet and getting exercise have been shown in earlier studies to protect against AMD, a leading cause of vision loss among people age 50 and older. Findings from this ...

A new computational model developed by scientists from the University of Chicago could help improve the allocation of U.S. biomedical research resources. The tool, called the Research Opportunity Index (ROI), measures disparities between resources dedicated to a disease and its relative burden on society. ROI identifies diseases that receive a disproportionate share of biomedical resources, which represent opportunities for high-impact investment or for the realignment of existing resources. It is designed to provide an unbiased, data-driven framework to help scientific ...

In the midst of ferry boats, container ships and tourists crowding Seattle's Elliott Bay, young salmon are just trying to get a decent meal. The fish hatch in the rivers and streams that feed into Puget Sound and almost immediately rely on eating small organisms near the shore, including in the heart of Seattle's commerce-filled waterfront. Though salmon share the busy Elliott Bay waters with boats and barges, scientists suspect built-up, "armored" shorelines and large piers may be the main culprits disrupting fish habitat. These artificial structures block light and ...

Reminders to take medication, delivered to patients via an electronic pillbox, may be able to improve adherence to tuberculosis (TB) treatment. The findings, reported this week in PLOS Medicine, are the result of a cluster randomized controlled trial by Shiwen Jiang of the Chinese Centers for Disease Control & Prevention, Katherine Fielding, of the London School of Hygiene & Tropical Medicine, and colleagues. The study randomized 36 districts in the provinces of Heilongjiang, Jiangsu, Hunan, and Chongqing, China to receive one of four approaches to tuberculosis case management: ...

Selective serotonin reuptake inhibitor (SSRI) use is modestly associated with violent crime, according to a study published this week in PLOS Medicine. The cohort study, by Seena Fazel from the University of Oxford, and colleagues, showed in subgroup analysis that this association was evident in participants aged 15-24, but not significant for individuals aged 25 and older. SSRIs are widely prescribed, but inconclusive evidence links SSRI use with violent behavior. In this study, Fazel and colleagues compared the rate of violent crime while individuals were prescribed ...

Giving electronic reminders to tuberculosis (TB) patients in China can reduce the amount of medication doses they miss by half, according to new research published in PLOS Medicine. Researchers from the London School of Hygiene & Tropical Medicine, UK, and the National Center for Tuberculosis Control and Prevention, China, conducted a trial with 4,173 patients from the provinces of Heilongjiang, Jiangsu, Hunan, and Chongqing. Patients either received text message reminders, an electronic medication monitor, both, or no reminders for their six month treatment period. Patients ...

Measuring how religion affects a person's political attitudes and behavior can provide powerful insight to everyone from pundits to presidents. Now there's a new strategy to gather better, more nuanced perspective on that religious influence than ever before, developed by University of Cincinnati researchers. UC's Andrew Lewis and Stephen Mockabee presented research titled "Measuring Biblical Interpretation and Its Influence on Political Attitudes" at the American Political Science Association's annual meeting earlier this month in San Francisco. The association serves ...

MEDFORD/SOMERVILLE, Mass. (Sept. 15, 2015) -- Regenerative medicine using stem cells is an increasingly promising approach to treat many types of injury. Transplanted stem cells can differentiate into just about any other kind of cell, including neurons to potentially reconnect a severed spinal cord and repair paralysis. A variety of agents have been shown to induce transplanted stem cells to differentiate into neurons. Tufts University biomedical engineers recently published the first report of a promising new way to induce human mesenchymal stem cells (or hMSCs, which ...

A quarter of a century ago, the physicist, physician and cell biologist Professor Thomas Jentsch and his research team opened up an entirely new field of research in the field of ion transport. Now the British journal "The Journal of Physiology"* has devoted a special section in its latest issue to his discovery. In this issue (DOI: 10.1113/jphysiol.2014.270043), Professor Jentsch, who leads a research group at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) and at the neighboring Leibniz-Institut für Molekulare Pharmakologie ...

New research from the USA suggests that college students are well aware that they should be personally responsible for their finances, including their card obligations, but this awareness rarely correlates with limiting the debts they accrue during their time in higher education. Details of the study are reported this month in the International Journal of Behavioural Accounting and Finance. Lucy Ackert of the Department of Economics and Finance, at Kennesaw State University, in Georgia, and Bryan Church of the Scheller College of Business, at Georgia Tech, Atlanta, ...

The most obvious disadvantage of putting your data in the cloud is losing access when you have no internet connection. According to research publishes in the International Journal of Cloud Computing, this is where "dew" could help. Yingwei Wang of the Department of Computer Science, at the University of Prince Edward Island, Charlottetown, Canada, describes what he refers to as a "cloud-dew" architecture that offers an efficient and elegant way to counteract cloud downtime and communication difficulties. In the world of cloud computing, users and organizations keep their ...

MANHATTAN, KANSAS - U.S. farmers are growing fewer types of crops than they were 34 years ago, which could have implications for how farms fare as changes to the climate evolve, according to a large-scale study by Kansas State University, North Dakota State University and the U.S. Department of Agriculture. Less crop diversity may also be impacting the general ecosystem. "At the national level, crop diversity declined over the period we analyzed," said Jonathan Aguilar, K-State water resources engineer and lead researcher on the study. The scientists used data from ...

LA JOLLA--Salk scientists have developed a new way to selectively activate brain, heart, muscle and other cells using ultrasonic waves. The new technique, dubbed sonogenetics, has some similarities to the burgeoning use of light to activate cells in order to better understand the brain. This new method--which uses the same type of waves used in medical sonograms--may have advantages over the light-based approach--known as optogenetics--particularly when it comes to adapting the technology to human therapeutics. It was described September 15, 2015 in the journal Nature ...

The addition of a daily outdoor activity class at school for three years for children in Guangzhou, China, resulted in a reduction in the rate of myopia (nearsightedness, the ability to see close objects more clearly than distant objects), according to a study in the September 15 issue of JAMA. Myopia has reached epidemic levels in young adults in some urban areas of East and Southeast Asia. In these areas, 80 percent to 90 percent of high school graduates now have myopia. Myopia also appears to be increasing, more slowly, in populations of European and Middle Eastern ...

Women are less likely than men to be full professors at U.S. medical schools, and receive less start-up support from their institutions for biomedical research, according to two studies in the September 15 issue of JAMA. Women now make up half of all U.S. medical school graduates. However, sex disparities in senior faculty rank persist in academic medicine. Whether differences in age, experience, specialty, and research productivity between sexes explain persistent disparities in faculty rank has not been studied. Anupam B. Jena, M.D., Ph.D., of Harvard Medical School, ...

Patients undergoing surgery for a hip fracture were older and had more medical conditions than patients who underwent an elective total hip replacement, factors that may contribute to the higher risk of in-hospital death and major postoperative complications experienced by hip fracture surgery patients, according to a study in the September 15 issue of JAMA. Although hip surgery can improve mobility and pain, it can be associated with major postoperative medical complications and mortality. Patients undergoing surgery for a hip fracture are at substantially higher risk ...

Women physicians are substantially less likely to be full professors than men of similar age, experience, specialty and research productivity. With recent increases in the number of women attending medical school, women now comprise nearly half of all new physicians. But the proportion of women at the rank of fullprofessor at U.S. medical schools has not changed since 1980, despite efforts to increase equity, according to a new research study led by Anupam Jena, associate professor of health care policy at Harvard Medical School. The results are published today in JAMA. "Many ...

A group of scientists from ITMO University, Australian National University and Aalto University called into question the results of a study, published by the researchers from Cambridge University in a prestigious scientific journal Physical Review Letters. In the original study, the British scientists claimed that they managed to find the missing link in the electromagnetic theory. The findings, according to the scientists, could help decrease the size of antennas in electronic devices manifold, promising a major breakthrough in the field of wireless communications. The ...

Drugs commonly used to treat high blood pressure, and prevent heart attacks and strokes, are associated with significantly worse cardiovascular outcomes in hypertensive African Americans compared to whites, according to a new comparative effectiveness research study led by researchers in the Department of Population Health at NYU Langone Medical Center. The study, published on September 15 in the Journal of the American College of Cardiology (JACC), is unique, the authors say, in that it evaluates racial differences in cardiovascular outcomes and mortality between hypertensive ...

Are climate predictions over periods of several years reliable if weather forecast are still only possible for short periods of several days? Nevertheless there are options to predict the development of key parameters on such long time scales. A new study led by scientists at GEOMAR Helmholtz Centre for Ocean Research Kiel shows how the well-known 11-year cycle of solar activity affects the long-time development of dominant large-scale pressure systems in the Northern Hemisphere. For their investigations the scientists used a coupled ocean-atmosphere model. In addition, ...

September 15, 2015 - Nyon, Switzerland A study from the University of Southampton and Sheffield Medical School in the UK projects a dramatic increase in the burden of fragility fractures within the next three decades. By 2040, approximately 319 million people will be at high risk of fracture -double the numbers considered at high risk today. In this first study to estimate the global burden of disease in terms of fracture probability, the researchers quantified the number of individuals worldwide aged 50 years or more at high risk of fracture in 2010 and projected figures ...

Marijuana use among American high school students is significantly lower today than it was 15 years ago, despite the legalization in many states of marijuana for medical purposes, a move toward decriminalization of the drug and the approval of its recreational use in a handful of places, new research suggests. The Johns Hopkins Bloomberg School of Public Health researchers say, however, that marijuana use is significantly greater than the use of other illegal drugs, with 40 percent of teens in 2013 saying they had ever smoked marijuana. That number was down from 47 percent ...
