Red wine contains resveratrol,...
Prehabilitation may benefit hip and knee replacement patients All hip and knee replacement patients have physical therapy after their surgery. However, a new study is suggesting that prehabilitation may be highly beneficial to some patients. Researchers found prehabilitation could significantly diminish the need for postoperative care. In some cases, postoperative care was cut by nearly 30 percent, resulting in a significant cost savings. The study included more than 4,700 patients and it found...
Higher dose flu vaccine may benefit older adults For older adults, it may be better to go with the high dose when it comes to the flu vaccine this year. A new study has found that the high dose influenza vaccine is 24 percent more effective than the standard dose vaccine in protecting adults 65 and older against influenza illness and its complications. The Fluzone high dose vaccine is an inactivated influenza vaccine that contains four times the amount of antigen in the standard dose Fluzone...
Stroke rates decreasing in older adults A new analysis has found that there has been a 40 percent decrease in the incidence of stroke in adults over the age of 65. The decline is much greater than researchers had expected and the decline occurred in both ischemic and hemorrhagic strokes. In addition, deaths due to strokes are also steadily declining in older adults. Stroke is the fourth leading cause of death in the United States, with approximately 795,000 strokes occurring each year. In the...
Brain implants may help restore memory loss Treatments for Alzheimer’s disease are severely lacking. Despite more than three decades of intense research and clinical trials, the only approved agents simply slow the progression of the disease. No agents have been able to reverse the damage caused by the disease. Now, researchers are taking a completely different approach. They are developing an implantable neural device to restore memory. Brain experts at the Lawrence Livermore National L...
Breath test may be important new tool against lung cancer Researchers have now come up with a new breath test that can diagnose patients with chronic obstructive pulmonary disease (COPD) as well as lung cancer.

The perspective here is the development of a non-traumatic, easy, cheap a...
A vibrating capsule may help combat chronic constipation Researchers in Israel are now reporting success with a vibrating capsule for constipation. You simply swallow it and it helps get your bowels moving. In a new study, the researchers found that the vibrating capsule helped nearly double the weekly bowel movements of patients suffering from chronic idiopathic constipation (CIC) and constipation predominant irritable bowel syndrome (C-IBS). “Despite the widespread use of medication to treat c...
Color-coded tags may signal food’s freshness Scientists have now come up with a color-coded smart tag that can tell consumers whether a carton of milk has turned sour. This technology could also tell you if a can of green beans has spoiled, all without opening the containers. “This tag, which has a gel-like consistency, is really inexpensive and safe, and can be widely programmed to mimic almost all ambient-temperature deterioration processes in foods,” said lead researcher Chao Zhang, who i...

The truth about spring allergies Every year we hear about how it may be the worse allergy season in years. But how true is it and are allergies a big problem than ever before? It turns out that several factors determine the severity of allergy season, such as weather patterns. While allergies are on the rise, affecting more and more Americans every year, each spring isn’t necessarily worse than the last, according to allergist Dr. Michael Foggs, who is the president of the American College of A...
Just how safe are e-cigarettes? There is considerable debate right now about whether e-cigarettes are a gateway to smoking or a gateway from smoking. For many adults age 50 and older, e-cigarettes may be a great way to transition off smoking. Ideally, if millions of people start using e-cigarettes as an aid to quit there could be a huge public health benefit. However, some health experts question whether e-cigarettes are just “an add-on” for chronic smokers and may be creating new problems. Cur...
Tomatoes potent in fighting breast cancer Eating a diet rich in tomato and tomato products may help protect against breast cancer. A new study by researchers in Ohio has found that eating a diet high in tomatoes had a positive effect on hormone levels that play a role in regulating fat and sugar metabolism. The researchers conducted a study with older women who were at high risk for breast cancer. “The advantages of eating plenty of tomatoes and tomato-based products, even for a short period, w...

Detecting Alzheimer’s disease in its earliest stages Australian scientists say they now are much closer to developing a screening test for the early detection of Alzheimer’s disease. The investigators have identified blood-based biological markers that are associated with the build-up of amyloid beta, a toxic protein in the brain. This plaque build-up develops years before symptoms appear and irreversible brain damage has occurred. “Early detection is critical, giving those at risk a much bette...
Wearing a contact lens at night may help restore age-related loss of near vision It may be possible to get rid of your reading glasses. Many older adults have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses. Now, a newly emerging technique called hyperopic orthokeratology (OK) may provide an alternative for restoring near vision without the need for glasses. Researchers have just completed a small study showing that wearing OK contact lenses overnight can...
New magnetic approach to treating heartburn It may be possible to replace your daily stomach medicine with a new magnetic device. It is called the LINX system and is composed of a series of titanium beads, each with a magnetic core. The beads are connected to form a ring shape and then implanted at the lower esophageal sphincter (LES), a circular band of muscle that closes the last few centimeters of the esophagus. The LES prevents the backward flow of stomach contents. This new medical device...
