No snowflake in an avalanche takes the blame.
Using the same database that the Centers for Disease Control and Prevention (CDC) uses to confirm the rise in obesity rates, researchers have concluded that 100 percent juice is not associated with young children being overweight or at risk for becoming overweight.
The research abstract, presented today at the Pediatric Academic Societies’ annual meeting in Toronto, looked at dietary intakes of 3,618 children ages 2-11 using the well-known National Health and Nutrition Examination Survey (NHANES).
According to Dr. Theresa Nicklas, “We did not…
New immigrants to Western nations are believed to experience fewer chronic health problems (e.g., diabetes, high blood pressure and heart disease) than long-time residents of those countries. Dr. Joel Ray and coauthors tested whether this "healthy immigrant effect" extends to complications during pregnancy.
In the Recent Immigrant Pregnancy and Perinatal Long-term Evaluation Study (RIPPLES), Ray and colleagues examined the incidence of maternal placental syndrome — defined as a diagnosis of pre-eclampsia or eclampsia (also called toxemia of pregnancy), placental abruption (a premature…
Most Americans are familiar with the popular city rankings of the fattest cities, the fittest cities, the most livable cities and the most expensive cities. Now, in the first-of-its-kind survey, the American Academy of Dermatology (Academy) has identified the cities that take sun protection seriously and those that fail to make the grade despite repeated health warnings.
"Based on our initial review of what people are currently doing, know and believe about sun protection, 35 percent of the national public score above average, with grades of A or B," said dermatologist Diane R. Baker, MD,…
As a group, young ADHD drivers are two to four times more likely to have a car accident than non-ADHD drivers. Daniel Cox, Ph.D., professor of psychiatry and neurosciences at the University of Virginia Health System, has conducted research aimed at improving those odds. His team's newest study will look at the effects of methylphenidate (MPH), a controlled-release stimulant, on young ADHD drivers facing real-life distractions.
"In controlled laboratory studies, there are no cell phones, no pressures to get home before curfew, no passengers encouraging the driver to 'get air,' no pets that…

Incorporating macadamia nuts into a heart healthy diet can reduce cardiovascular disease risks according to Penn State researchers.
"We looked at macadamia nuts because they are not currently included in the health claim for tree nuts, while other tree nuts are recommended as part of a healthy diet," says Dr. Amy E. Griel, recent Ph.D. recipient in nutritional sciences. "Macadamia nuts have higher levels of monounsaturated fats, like those found in olive oil compared with other tree nuts."
The researchers used a controlled feeding study to compare a heart-…
Tart cherries may be good for more than just making pie, according to new data from an animal study conducted by University of Michigan Health System researchers and presented today at a major scientific meeting.
In a study involving rats, the researchers report that animals that received powdered tart cherries in their diet had lower total cholesterol, lower blood sugar, less fat storage in the liver, lower oxidative stress and increased production of a molecule that helps the body handle fat and sugar, compared with rats that didn't receive cherries as part of an otherwise similar diet.…
Over time, more women are developing multiple sclerosis (MS) than men, according to research that will be presented at the American Academy of Neurology’s 59th Annual Meeting in Boston, April 28 – May 5, 2007.
In 1940, the ratio of women to men with MS in the United States was approximately two to one. By 2000, that ratio had grown to approximately four to one.
“That’s an increase in the ratio of women to men of nearly 50 percent per decade,” said study author Gary Cutter, PhD, of the University of Alabama at Birmingham School of Public Health. “We don’t yet know why more women are…
Armed with more than a decade’s worth of statistics, researchers are sounding a new alarm about growing rates of syphilis among gay and bisexual men.
The overall number of syphilis cases in the United States fell from 50,578 in 1990 to just 7,177 in 2003 perhaps because of a nationwide prevention campaign aimed at heterosexuals. Nevertheless, gay men have seen their rates rise significantly in this decade.
"The entire nation was caught unawares," said study lead author James Heffelfinger, M.D., a medical epidemiologist with the Centers for Disease Control and Prevention. "You’re…
One out of three sexually active older adults infected with HIV has unprotected sex, according to a study by Ohio University researchers. A survey of 260 HIV-positive older adults found that of those having sex, most were male, took Viagra and were in a relationship.
AIDs cases among the over-50 crowd reached 90,000 in 2003. According to the Centers for Disease Control and Prevention, they will account for half of all HIV/AIDS cases in the United States by 2015 because medical intervention has extended the lifespan of those infected with HIV. Additionally, drugs such as Viagra have made it…
A new study says targeting smaller (¡Ü5 mm) lesions does little to significantly reduce the incidence of colorectal cancer (CRC) and, in fact, results in extremely high financial costs and a large proportion of adverse events. Published in the June 1, 2007 issue of CANCER, a peer-reviewed journal of the American Cancer Society, a cost-benefit analysis study says the low malignancy rate among so-called diminutive polyps gives virtual colonoscopy with removal of lesions 6 mm or greater the best estimated value per life year gained and with fewer complications.
Effective screening through…
