The National Institutes of Health is partnering with researchers from 10 rival drug companies and several nonprofit organizations to develop new and earlier treatments for diseases including diabetes, Alzheimer's and lupus.
The partnership, announced Tuesday by NIH director Dr. Francis Collins, "could change the way scientific research is conducted."
"This is an unprecedented partnership, bringing the best and brightest scientists from the public and the private sectors together to discover the next generation of drug targets that are going to transform our ability to treat Alzheimer’s disease, diabetes, rheumatoid arthritis, lupus, and that's just getting started,” Collins said.
The consortium will be known as the Accelerating Medicines Partnership. It will focus at first on three disease groups: Alzheimer's, diabetes and autoimmune diseases including rheumatoid arthritis and lupus.

Although the world of medicine has made incredible progress when it comes to tackling certain illnesses, scientists still have not been able to find the cure for the common cold. But there are ways to prevent colds as well as treat them. The question is, which are the most effective?
According to a review in the recent edition of the Canadian Medical Association Journal, hand washing and possibly taking zinc seem to be the best ways to avoid getting sick. Investigators reviewed 67 randomized controlled trials that showed hand washing as well as alcohol disinfectants are the best ways to ward off colds.
Zinc was found to work mostly in children, with two trials showing that little ones who took 10 to 12 milligrams of zinc sulfate every day had fewer colds and fewer absences from school because of colds. Authors of the study suggest that zinc could work for adults. Vitamin C, the "gold standard" of cold fighters, did not seem as effective.

Having shingles, especially when you are younger, may increase your risk of having a stroke or heart attack later in life, according to a new study published this week in the online issue of Neurology.
Shingles is caused by the varicella zoster virus, according to the Centers for Disease Control and Prevention. It's the same virus that causes chickenpox. Also called herpes zoster, shingles appears as a painful rash, which in some cases can lead to further infection if left untreated. Doctors say the virus remains dormant in the nerve roots of people who have had chickenpox; anyone who has the virus as a child may develop an outbreak of shingles later on.
In this study, British researchers looked at more than 105,000 people who had had shingles and more than 213,000 people who had not. They found people aged 18 to 40 who had shingles were more likely to have a stroke, warning stroke (also known as a transient ischemic attack), or heart attack later in life.

Patients who use certain acid-suppressing drugs for heartburn over a period of two years or longer are more likely to suffer from a vitamin B12 deficiency than those who do not use them, according to a new study released Tuesday.
The drugs, known as proton-pump inhibitors (PPI) and histamine 2 receptor antagonists (H2 blockers), are available by prescription and over-the-counter, under names such as Prilosec and Nexium. They are designed to treat gastroesophageal reflux disease, or GERD, as well as other acid-related conditions.

Women who used birth control pills for three years or more have twice the risk of developing glaucoma later in life, according to new research.
Glaucoma is a disease that damages the eye’s optic nerve and is a leading cause of blindness in the United States.
It’s been well documented that low-estrogen levels following menopause contribute to glaucoma in women. Scientists don’t know exactly why this happens. But years of using birth control pills, which can also lower estrogen levels, may add to the problem.
The study, conducted by researchers at University of California, San Francisco, Duke University School of Medicine and Third Affiliated Hospital of Nanchang University, Nanchang, China, did not differentiate between women who took low-estrogen or regular birth control pills. Investigators theorize that when women are not on the pill, their natural estrogen levels go up and down, which seems to prevent the eye from developing glaucoma. When women go on the pill, their estrogen levels are consistent, and in some cases consistently low, which could cause them to develop the condition.
This research project is the first to suggest an increased risk of glaucoma in women who have used oral contraceptives for three or more years. The researchers looked at data on more than 3,400 women aged 40 and older from across the United States, who answered questionnaires about their reproductive health and eye exams. FULL POST

It’s become the hot new treatment for older men. “T,” or testosterone replacement therapy, has been touted as the new way to turn back a man’s body clock and improve his sexual performance.
But there may be trouble in paradise, according to new research. In a study published this week in the Journal of the American Medical Association, scientists have found that men taking testosterone therapy had a 29% greater risk of death, heart attack and stroke than those who were not on the hormone replacement.
The study included 8,709 men with low testosterone levels, who underwent coronary angiography, a procedure used to open narrow or blocked coronary arteries, in the Veterans Affairs (VA) system between 2005 and 2011. Some were found not to have blockages.
Researchers found the number of patients experiencing heart problems such as attacks and strokes three years after their angiographies, was 19.9% for those who were not on testosterone and 25.7% for those who were. Even when scientists accounted for other factors in the patients’ health, the increase of heart events in those on testosterone therapy was significant, according to the study.

New evidence suggests taking vitamin B supplements may help reduce the risk of stroke.
A study, published this week in the online issue of Neurology, analyzed 14 randomized clinical trials of vitamin B that included a total of 54,913 participants. All of the studies compared the supplement use with a placebo or a very low-dose B vitamin. The patients were then followed for a minimum of six months.
The purpose of this meta-analysis was to see if vitamin B lowered homocysteine levels in the blood, which are associated with atherosclerosis (hardening and narrowing of the arteries), as well as an increased risk of heart attacks, strokes, blood clot formation and possibly Alzheimer's disease.
"Previous studies have conflicting findings regarding the use of vitamin B supplements and stroke or heart attack," said study author Dr. Xu Yuming, with Zhengzhou University in Zhengzhou, China. "Some studies have even suggested that the supplements may increase the risk of these events."

Copper, which is found in anything from drinking water to red meats, may be an environmental trigger of Alzheimer’s disease, according to a new study.
The study, published Monday in the journal Proceedings of the National Academy of Sciences, suggests copper keeps toxic proteins from leaving the brain.
It is clear that, over time, copper impairs the systems through which amyloid beta is removed from the brain, said Rashid Deane, a research professor in the University of Rochester Medical Center Department of Neurosurgery, member of the Center for Translational Neuromedicine, and lead author of the study. This causes the protein "to accumulate in the brain and form the plaques that are the hallmark of Alzheimer's disease." FULL POST

Choking is a leading cause of injury in children, according to the American Academy of Pediatrics, especially those four years and younger. Although the number of choking incidents involving toys and toy parts has gone down in the last 20 years due to manufacturer and federal government warnings, the number of food-choking cases in youngsters is still high.
"We have done a great job in this country (of) preventing choking in children on toys, “says Dr. Gary Smith, co-author of a new study on choking injuries and a professor of pediatrics at The Ohio State University College of Medicine. “Since the 1990s we've had laws and regulations, systems where we can monitor these injuries when they happen. We have no such systems in place currently for food."
The Research Institute at Nationwide Children's Hospital in Columbus, Ohio, reviewed thousands of statistics on children who had choking-related emergency room visits between 2001 to 2009. The study authors found that an average of 12,400 children under the age of 15 were treated for non-fatal, food-related choking each year, which equals about 34 children per day.

Hormone replacement therapy has been a controversial issue for a lot of women over the last decade. Many have rejected any type of hormone therapy since a large, federally funded study found hormone replacement therapy could increase a woman’s risks for heart disease and strokes.
Now, a new study out of Yale School of Medicine suggests anywhere from 18,000 to 91,000 women in their 50s who had hysterectomies may have died prematurely in the last decade because they did not take estrogen-only hormone replacement therapy.
