During the past two decades there has been a significant increase in the percentage of patients who have a high number of lymph nodes evaluated during colon cancer operations, but this improvement is not associated with an increase in the overall proportion of colon cancers that are node positive, according to a study in the September 14 issue of JAMA.
While the incidence of the life-threatening condition of aortic dissection is significantly higher than in the general population, it remains low among patients with the congenital heart defect, bicuspid aortic valve; however, the incidence of aortic aneurysms is significantly high, according to a study in the September 14 issue of JAMA.
The use of stronger graduated driver licensing programs for 16- to 19-year old drivers in the U.S. that included restrictions on nighttime driving and allowed passengers were associated with a lower incidence of fatal crashes among 16-year old drivers, but a higher incidence among 18-year olds, according to a study in the September 14 issue of JAMA.

New research from the University of Alabama at Birmingham pinpoints the relationship between primary brain tumors and the onset of epileptic seizures and reveals that a drug used to treat Crohn’s disease inhibits those seizures and may be able to slow a tumor’s growth. The onset of seizures is a common symptom in gliomas and often is the first sign of a brain tumor. Sen. Ted Kennedy had a seizure in May 2008, and three days later doctors confirmed that he had a malignant glioma. Kennedy died the following year.

Nearly 50,000 Americans are diagnosed each year with stage III or locally advanced NSCLC, for which surgery is usually not a viable treatment option. Optimizing nonsurgical treatment strategies for these patients is an ongoing research endeavor.

Patients with narrowed arteries in the brain who received intensive medical treatment had fewer strokes and deaths than patients who received a brain stent in addition to medical treatment, according to the initial results from the first, nationwide stroke prevention trial to compare the two treatment options. The results of the National Institutes of Health (NIH) study called Stenting versus Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) are published in the online first edition of the New England Journal of Medicine.
An article appearing in the Sept. 7 New England Journal of Medicine, reporting on NIH research on brain stents, says aggressive medical treatment without stenting is better for high-risk stroke patients. But experts at Cedars-Sinai Medical Center who were involved in the study believe this procedure is appropriate for some patients. They say this study is a helpful start but not likely to be the final word on understanding when stenting may be appropriate, and raise concerns about several study limitations and exclusions.
People who received intensive medical treatment following a first stroke had fewer second episodes and were less likely to die than people who received brain stents in addition to medical treatment, according to a new report in the New England Journal of Medicine, to be published online Sept. 7. All patients in the study had experienced one stroke and were considered at high risk for a second one.

Contradicting the long-held medical belief that the risk of cardiovascular death for women spikes sharply after menopause, new research from Johns Hopkins suggests instead that heart disease mortality rates in women progress at a constant rate as they age.
Psychogenic non-epileptic seizures may go undiagnosed for much longer in veterans compared to civilians, according to a new study published in the September 6, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology. This type of seizure is different from seizures related to epilepsy and is thought to have a psychological origin.
Thousands of scientists around the world are working on AMPK but the McMaster team is the first to demonstrate its essential role in exercise. Their research appears in the current issue of the Proceedings of the National Academy of Sciences.

Researchers at Albert Einstein College of Medicine of Yeshiva University report in the September 4 online edition of Nature Medicine that they have developed a tuberculosis (TB) vaccine candidate that proved both potent and safe in animal studies. According to the World Health Organization, TB kills an estimated 1.7 million people each year and infects one out of three people around the globe. With drug-resistant strains spreading, a vaccine for preventing TB is urgently needed.
The American Thoracic Society has issued the first-ever guidelines on the use of fractional exhaled nitric oxide (FENO) address when to use FENO and how to interpret FENO levels in different clinical settings. The guidelines, which appear in the September 1 American Journal of Respiratory and Critical Care Medicine, are graded based on the available evidence in the literature.
With citizens’ groups seeking government regulation of foul-smelling ammonia emissions from large dairy farms, scientists today reported that adding natural plant extracts to cow feed can reduce levels of the gas by one-third while reducing the need to fortify cow feed with expensive protein supplements. They reported here at the 242nd National Meeting & Exposition of the American Chemical Society (ACS).
Many common signs of aging, such as shaking hands, stooped posture and walking slower, may be due to tiny blocked vessels in the brain that can’t be detected by current technology.
In things thick and thin: Cornell physicists explain how fluids – such as paint or paste - behave by observing how micron-sized suspended particles dance in real time. Using high-speed microscopy, the scientists unveil how these particles are responding to fluid flows from shear – a specific way of stirring.
Although several genes have been linked to amyotrophic lateral sclerosis (ALS), it is still unknown how they cause this progressive neurodegenerative disease. In a new study, Columbia University Medical Center (CUMC) researchers have demonstrated that two ALS-associated genes work in tandem to support the long-term survival of motor neurons. The findings were published in the September 1 online edition of the Journal of Clinical Investigation.

The newly released Smoking Prevalence, Savings, and Treatment (SmokingPaST) Framework is a tool designed to calculate the impact of investments in tobacco treatment programs on health and medical cost savings. The framework combines what is already known about the medical costs of smoking, the health benefits of quitting and the effectiveness of different quit methods.
With almost 100 million people in developing countries exposed to dangerously high levels of arsenic in their drinking water, and unable to afford complex purification technology, scientists today described a simple, inexpensive method for removing arsenic based on chopped up pieces of ordinary plastic beverage bottles coated with a nutrient found in many foods and dietary supplements.
The potato’s stereotype as a fattening food for health-conscious folks to avoid is getting another revision today as scientists report that just a couple servings of spuds a day reduces blood pressure almost as much as oatmeal without causing weight gain. Scientists reported on the research, done on a group of overweight people with high blood pressure, at the 242nd National Meeting & Exposition of the American Chemical Society (ACS), being held here this week.
