Boosting body’s natural flu killers as way to offset virus mutation problem

Emergence of new influenza strains, such as the recent avian influenza (H5N1) and swine influenza (H1N1 2009), can lead to the emergence of severe pandemics that pose a major threat to the entire world population. Recently, the concern regarding the emergence of such a pandemic arose when a new and deadly avian influenza strain (H7N9) was discovered in China, causing the death of six people in only one month. The body’s immune system can fight influenza infection. Natural killer (NK) cells, which are an essential component of this system, can recognize and eliminate influenza-virus-infected cells and inhibit the spread of the virus in the respiratory system…

More doctors, hospitals using electronic records

The Obama administration says more doctors and hospitals are embracing technology as adoption of computerized medical records reaches a “tipping point” in America. A report Wednesday from Health and Human Services says more than 50 percent of doctors' offices and 4 in 5 hospitals have transitioned from paper to electronic records, thanks partly to more than $14 billion in government incentive payments. The hope is that electronic records will make caring for patients safer and less costly, by helping avoid mistakes and cutting down on duplication. But others say there's still a long way to go. An outside group's report last year found little progress in getting medical computers in different offices to talk to each other. Concerns have also surfaced about patient privacy and vulnerability to fraud.source : http://www.foxnews.com/health/2013/05/23/more-doctors-hospitals-using-electronic-records/

Sugary drinks tied to kidney stone risk

Adults who drink at least one sugar-sweetened drink a day are slightly more likely to develop kidney stones than people who rarely imbibe them, according to a new study. While the recommendation for kidney stone prevention has been to drink a lot of fluids, the study suggests that it's not just the amount of fluid but the type of drink that also matters. Dr. Gary Curhan, the senior author of the study, said patients often ask for dietary advice to help prevent kidney stones. While the recommendation has been to drink plenty of fluids, Curhan said, patients often ask, “what should I drink? There's a lot of lore out there.” To see whether the type of beverage might matter, Curhan, of the Channing Division of Network Medicine at Brigham and Women's Hospital, and his colleagues collected data from three massive surveys of nearly 200,000 people. The questionnaires surveyed participants every two to four years and asked about diet, lifestyle and health, including how much they drank certain beverages and whether they developed kidney stones. None of the people in the study had kidney stones at the start. They found that 159 out of every 100,000 people who drank a sugar-sweetened non-cola beverage, such as clear soda, less than once a week developed kidney stones, compared to 306 out of every 100,000 who drank soda daily. After accounting for other factors, that translated to a 33 percent greater chance of developing kidney stones. Frequent punch drinkers also had an 18 percent higher chance of developing kidney stones. For every 100,000 people who drank punch at least every day, 226 developed kidney stones, compared to 158 out of every 100,000 participants who had punch less than once a week. Curhan said that while the numbers of people developing kidney stones in each group are not enormously different, the increased risk spread across an entire population is quite big. “Sodas are so commonly used that even though the absolute rate doesn't look that different, if there's a huge number of people consuming it, then the magnitude on the public health can be quite substantial,” Curhan told Reuters Health. Other drinks, such as coffee, tea, wine, beer and orange juice were tied to a lower risk of developing kidney stones. For instance, 205 out of every 100,000 people who rarely drank coffee developed kidney stones, compared to 137 out of every 100,000 people who drank it daily. Just 96 out of every 100,000 people who drank red wine daily developed kidney stones, while 174 out of every 100,000 people who drank red wine less than once a week developed kidney stones. Curhan's study, published in the Clinical Journal of the American Society of Nephrology, follows others showing a link between stones and fructose, non-dairy calcium, vitamin C supplements and other factors. The new study doesn't prove cause-and-effect between certain drinks and kidney stones, but it's possible that sugar could be involved, Curhan said, because it might play a role in how the body handles calcium. Another possibility is that sugary drinks might be contributing to obesity, and obesity is also tied to a higher kidney stone risk, said Dr. Elaine Worcester, a professor at the University of Chicago, who was not part of the study. Despite the lack of proof of a cause-effect relationship, Worcester said “these kinds of studies are the best we have to give advice to our patients.”source : http://www.foxnews.com/health/2013/05/23/sugary-drinks-tied-to-kidney-stone-risk/

New drug could reduce asthma attacks by 87 percent

An experimental drug being developed by Regeneron Pharmaceuticals Inc. and Sanofi SA showed promising results during a small, mid-stage clinical trial in treating a subset of patients with moderate to severe asthma, but some physicians cautioned that it was too early to say how effective the treatment may ultimately be. The drug, dupilumab, is considered one of Regeneron's most promising pipeline drugs and could eventually reach $750 million in annual U.S. sales if it gains U.S. approval to treat asthma, according to Barclays. Regeneron and Sanofi, which have a partnership to co-develop certain experimental drug programs, are also testing the drug to treat a type of eczema, the itchy skin condition, and have said dupilumab could eventually be applied to other allergic conditions. Results from the trial, published online Tuesday in the New England Journal of Medicine, showed that dupilumab reduced asthma attacks by 87 percent in patients taking the drug compared to those receiving a placebo. Side effects of the drug appeared to be relatively consistent with those of patients taking placebos. “It really raises the possibility that we've hit upon a fundamental pathway that's driving the allergic reaction in asthma,” said George D. Yancopoulos, Regeneron's chief scientific officer, in an interview. However, the trial was relatively small, enrolling 52 patients in each of the study's two treatment groups. An editorial accompanying the study results said the trial design, in which patients were gradually weaned off of standard therapies for asthma, did not reflect a “real world” environment. It's also unclear how large a swath of asthma patients will benefit from the drug, because only those with higher-than-normal disease-fighting white blood cells were admitted to the study, Michael E. Wechsler, director of the asthma program at National Jewish Health, a Denver-based research hospital that specializes in respiratory conditions, wrote in the editorial. Just 21 percent of patients screened for the trial met the inclusion criteria, Dr. Wechsler wrote. Asthma affects more than 24 million people in the U.S., but existing therapies are unable to control the condition for as many as 10 percent to 20 percent of patients, according to the study's authors.

Cancer and birth defects in Iraq: The nuclear legacy

The radioactive element uranium is widely dispersed throughout Earth’s crust and is much sought after as a fuel for nuclear power plants and for use in weapons. Depleted uranium (DU), commonly used in modern munitions such as defensive armour plating and armour-piercing projectiles, is 40 per cent less radioactive than natural uranium, but remains a significant and controversial danger to human health. The World Health Organisation (WHO) sets a maximum uranium exposure of 1 millisievert (mSv) per year for the general public, but environmental scientists at the University of Mosul and the Institute of Forest Ecology, Universitaet für Bodenkultur (BOKU), Vienna, Austria, led by Riyad Abdullah Fathi have measured significant levels of uranium in soil samples from three sites in the province of Nineveh in the north of Iraq. Writing in the journal Medicine, Conflict and Survival, Fathi and colleagues link their findings with dramatic increases in cancers reported to the Mosul Cancer Registry and the Iraqi national cancer registry (which began collecting data in 1975)…

Low radiation scans help identify cancer in earliest stages

Results of the study will be presented at the ATS 2013 International Conference. "Lung cancer is the leading cause of cancer-related death and has a poor survival rate," said Sue Yoon, nurse practitioner at VA Boston HealthCare West Roxbury Division. "Most of our veterans in these ages have a heavy smoking history and early screening is desirable to improve outcomes. Our study was undertaken to learn how often we would discover significant abnormalities and how to adapt our existing processes and interdisciplinary approaches to accommodate additional patients." Conducted according to guidelines set forth by the National Comprehensive Cancer Network (NCCN), the study was based in part on the results of the National Lung Cancer Screening Trial (NLST) which found that LDCT resulted in a 20 percent reduction of lung cancer mortality compared to chest x-ray among heavy smokers aged 55 to 74 years. …

Scientists uncover how grapefruits provide a secret weapon in medical drug delivery

Grapefruits have long been known for their health benefits, and the subtropical fruit may revolutionize how medical therapies like anti-cancer drugs are delivered to specific tumor cells. University of Louisville researchers have uncovered how to create nanoparticles using natural lipids derived from grapefruit, and have discovered how to use them as drug delivery vehicles. UofL scientists Huang-Ge Zhang, D.V.M., Ph.D., Qilong Wang, Ph.D., and their team today (May 21, 2013), published their findings in Nature Communications. …
