Research: Effect of telehealth on use of secondary care and mortality: findings from the Whole System Demonstrator cluster randomised trial Editorial: Telehealth for long term conditions For people with long term conditions, telehealth can reduce deaths and help patients avoid the need for emergency hospital care, finds a study published on bmj.com today. However, the estimated scale of hospital cost savings is modest and may not be sufficient to offset the cost of the technology, say the authors. Telehealth uses technology to help people with health problems live ...

It might be possible for human-to-human airborne transmissible avian H5N1 influenza viruses to evolve in nature, new research has found. The findings, from research led by Professor Derek Smith and Dr Colin Russell at the University of Cambridge, were published today, 22 June in the journal Science. Currently, avian H5N1 influenza, also known as bird flu, can be transmitted from birds to humans, but not (or only very rarely) from human to human. However, two recent papers by Herfst, Fouchier and colleagues in Science and Imai, Kawaoka and colleagues in Nature reveal ...

Alexandria, VA – In the 1980s, acid rain was a big topic of conversation. Everyone knew about it. Today, just a couple of decades later, it's all but been forgotten. Why and how did this happen? As EARTH explores in the July issue, the problem of acid rain has largely been solved. The solution started with congressional amendments to the Clean Air Act in 1990 that called for government regulation of sulfur dioxide emissions, a known cause of acid rain. Two decades later, sulfur dioxide emissions have been halved and previously damaged waterways and forests have largely ...

Scientists at Emory University School of Medicine have identified a new type of anti-inflammatory compound that may be useful in treating a wide range of conditions, including neurodegenerative and autoimmune diseases. These compounds inhibit the enzyme Nox2, part of a family of enzymes responsible for producing reactive oxygen species (ROS). The results were published Thursday in the journal Chemistry & Biology. "Nox2 inhibitors could be valuable with many conditions where inflammation plays a role," says senior author David Lambeth, MD, PhD, professor of pathology ...

Researchers at the University of Liverpool have developed new methods to track stem cells and further understanding of what happens to them after they have been in the body for a significant period of time. Stem cells are used to treat conditions such as leukaemia and have the potential to treat many more diseases and disorders where patient survival is reliant on organ and tissue donation. Currently, however, it is difficult for medics to establish whether stem cells have survived following transplantation in the body and if they reach their target site or migrate elsewhere. In ...

Cigarette smoking among drug dependent pregnant women is alarmingly high, estimated at 77 to 99%. Programs that treat pregnant patients for substance use disorders often fail to address cigarette smoking despite the clear risks to both mother and child, including ectopic pregnancy, spontaneous abortion, preterm delivery, low birth weight, and Sudden Infant Death Syndrome. However, programs to help people quit smoking do not seem to interfere with drug abuse treatment, and may actually improve drug abstinence rates. One of the most effective methods of helping people ...

The purified proteins by the Department of Biotechnology of Neiker-Tecnalia have demonstrated their ability to inhibit the growth of several tumor cell lines. This property shows that the latex proteins of this plant, which is very prolific and easily acclimated, could be considered in clinical trials for cancer treatment due to its anti-tumor activity. The research has been done in collaboration with the University of Oviedo (Spain) and with funding from the Department for the Environment, Territorial Planning, Agriculture and Fisheries of the Government of the Basque ...

Graphene, an ordered monolayer of carbon, is the thinnest substance known, and yet has extraordinary mechanical strength. A new study shows that its two-dimensional network of atoms can even trap light. Thin, thinner, graphene. Graphene, a monolayer of carbon in which the atoms are arranged in a two-dimensional honeycomb network, is the thinnest net in the world, is highly stable. Andre Geim and Konstantin Novoselov received the Nobel Prize for Physics in 2010 for their discovery of the electrical conductivity of graphene. Indeed, graphene could in future replace silicon ...

Researchers from the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa (uOttawa) have found a protein in the blood of pregnant women that can predict if they are likely to have a fetus that doesn't grow properly, and thus has a high risk of stillbirth and long-term health complications. The research, led by Dr. Andrée Gruslin, could lead to a widely available blood test and could help develop ways for improving the outcomes of women and their children who face this risk — estimated to be as many as one of every 20 pregnancies. Dr. Gruslin's study, ...

EAST LANSING, Mich. — Poor mothers will invest more resources in daughters, who stand a greater chance of increasing their status through marriage than do sons, suggests a study in the American Journal of Physical Anthropology. Masako Fujita, Michigan State University anthropologist, and her fellow researchers tested the breast milk of mothers in northern Kenya and found that poor mothers produced fattier milk for their daughters than for their sons. On the contrary, mothers who were better off financially favored sons over daughters. The results, also featured in ...

ANN ARBOR, Mich. — For many adult women, supporting tissues in and around their vagina weaken to the point where the bladder and other organs descend from their normal position, creating a hernia into the vaginal wall known as pelvic organ prolapse. One in five women will undergo surgery to repair such prolapse. Vaginal surgery is one way to correct this condition, which often comes with age, but this surgery can also unmask another problem – urinary leakage. Now, new research by the University of Michigan Health System shows that patients who receive a mid-urethral ...

University of Southampton researchers are pioneering a new way of measuring and monitoring the impact of industrial and agricultural development on the environment. Working in collaboration with East China Normal University, the Nanjing Institute of Geography and Limnology and the University of Dundee, the team has created the world's first long-term record of ecosystem health, which examines the past condition of environmental resources in China's Yangtze basin region, and helps develop forecasts for the future. "We have examined what effect modern intensive farming ...

PROVIDENCE, R.I. [Brown University] — Selenium is an inexpensive element that naturally belongs in the body. It is also known to combat bacteria. Still, it had not been tried as an antibiotic coating on a medical device material. In a new study, Brown University engineers report that when they used selenium nanoparticles to coat polycarbonate, the material of catheters and endotracheal tubes, the results were significant reductions in cultured populations of Staphylococcus aureus bacteria, sometimes by as much as 90 percent. "We want to keep the bacteria from generating ...

Children born by mothers who have of consumed between 1 and 6 alcohol units per week are just as intelligent and well-developed as children of abstaining mothers. Mothers who have been drinking 5 or more drinks on a single occasion a limited number of times before realizing that they were pregnant may also breathe a sigh of relief; their children have not been harmed. These are the findings of one of the most comprehensive studies done so far in this field on a global scale. The research project has resulted in a series of papers, which will be published today in the ...

In the midst of continued economic uncertainty, financial issues loom large on the minds of many Americans. According to a recent report from the Chicago Tribune, retirement planning is something that more and more Americans are beginning to think critically about. For many Americans, however, issues such as retirement savings and estate planning are daunting, at best. For this reason, many Americans are seeking the services of financial planners--and independent broker-dealer NEXT Financial Group Inc. (NEXT) is devoted to providing high standards of service and investment ...

A team of NOAA-supported scientists is predicting that this year's Gulf of Mexico hypoxic zone could range from a low of approximately 1,197 square miles to as much as 6,213 square miles. The wide range is the result of using two different forecast models. The forecast is based on Mississippi River nutrient inputs compiled annually by the U.S. Geological Survey (USGS). The smaller dead zone forecast, covering an area slightly larger than the state of Rhode Island, comes from researchers from the University of Michigan. Their predicted size is based solely on the current ...

Multiple sclerosis (MS) patients appear to have a lower cancer risk, according to a new study led by researchers at the University of British Columbia and Vancouver Coastal Health. The study, published in the current issue of the journal Brain, is the first to investigate overall cancer risk in MS patients in North America. "Because the immune system plays important roles in both cancer and MS, we wanted to know whether the risk of cancer is different for people with MS," says Elaine Kingwell, the study's lead author and a postdoctoral fellow in the UBC Faculty of Medicine ...

According to researchers at Moffitt Cancer Center, cancer is subject to the evolutionary processes laid out by Charles Darwin in his concept of natural selection. Natural selection was the process identified by Darwin by which nature selects certain physical attributes, or phenotypes, to pass on to offspring to better "fit" the organism to the environment. As applied to cancer, natural selection, a key principle of modern biology, suggests that malignancies in distinct "microhabitats" promote the evolution of resistance to therapies. However, these same evolutionary ...

Despite modest gains in lifespan over the past century, the United States still trails many of the world's countries when it comes to life expectancy, and its poorest citizens live approximately five years less than more affluent persons, according to a new study from Rice University and the University Colorado at Boulder. The study, "Stagnating Life Expectancies and Future Prospects in an Age of Uncertainty," used time-series analysis to evaluate historical data on U.S. mortality from the Human Mortality Database. The study authors reviewed data from 1930 through 2000 ...

A new type of paint made with carbon nanotubes at Rice University can help detect strain in buildings, bridges and airplanes. The Rice scientists call their mixture "strain paint" and are hopeful it can help detect deformations in structures like airplane wings. Their study, published online this month by the American Chemical Society journal Nano Letters details a composite coating they invented that could be read by a handheld infrared spectrometer. This method could tell where a material is showing signs of deformation well before the effects become visible to the ...

Dr. Marvell Scott is a sports medicine expert and ...

MANHATTAN, KAN. -- Racial profiling has gained national attention in recent years, and a Kansas State University researcher is finding that it can involve an additional factor: gender. Jeremy Briggs, doctoral candidate in sociology, Topeka, is analyzing police actions during routine traffic stops to understand how race and gender are connected. Perhaps one of his most significant findings is that black and Hispanic women are just as likely as white men to be ticketed, arrested or searched during a traffic stop. "Racial profiling has really come back into political discussions, ...

WASHINGTON — Twelve years into a multibillion-dollar state and federal effort to save the Florida Everglades, little progress has been made in restoring the core of the ecosystem, says a new congressionally mandated report from the National Research Council. Expedited restoration projects that improve the quality and amount of water in this area are necessary to reverse ongoing declines. A new federal pilot project offers an innovative approach to this challenge, although additional analysis is needed to maximize restoration benefits within existing legal constraints. ...

WINSTON-SALEM, N.C. – June 21, 2012 – Regenerative medicine researchers at Wake Forest Baptist Medical Center have reached an early milestone in a long-term project that aims to build replacement kidneys in the lab to help solve the shortage of donor organs. In proof-of-concept research published online ahead of print in Annals of Surgery, the team successfully used pig kidneys to make "scaffolds" or support structures that could potentially one day be used to build new kidneys for human patients. The idea is to remove all animal cells – leaving only the organ structure ...

ROCHESTER, Minn. -- Mayo Clinic researchers have discovered an association between a commonly prescribed blood pressure drug, Olmesartan, and severe gastrointestinal issues such as nausea, vomiting, diarrhea, weight loss and electrolyte abnormalities -- symptoms common among those who have celiac disease. The findings are published online today in the medical journal Mayo Clinic Proceedings. From 2008-11, Mayo Clinic physicians treated 22 patients with symptoms similar to celiac disease, including intestinal inflammation and abnormalities. Patients came from 17 states, ...
