Last year's flu season was one of the worst in recent memory, Centers for Disease Control and Prevention Director Dr. Tom Frieden said Thursday, and although this season is off to a slower start, people should still get flu vaccines.
"Last year was a relatively severe season," Frieden said, noting that 381,000 people were hospitalized, and 169 children died from the flu. "This is higher than we've seen in many flu seasons."
The good news, Frieden said, is that the flu vaccine prevented millions of illnesses. "We estimate that during last year's flu season, flu vaccination prevented 6.6 million people from getting sick with the flu, 3.2 million from going to see a doctor and at least 79,000 hospitalizations." FULL POST

Cases of human papillomavirus (HPV) have significantly decreased since the advent of the HPV vaccine in 2006, according to the Centers for Disease Control and Prevention, and numbers have outpaced even their greatest predictions.
"The prevalence of the types of HPV that commonly cause cervical cancer in women has dropped by about half in girls ages 14 to 19," said Dr. Thomas Frieden, CDC director. "That decline is even better than we had hoped for." FULL POST

Sticking to a Mediterranean diet may not just be good for your heart, it may be good for your brain as well, according to a new study.
Researchers in Spain followed more than 1,000 people for six and a half years, and found that participants who were on a Mediterranean diet and supplemented that diet with extra nuts or olive oil performed better on cognitive tests at the end of the study period than the control group, which followed a lower-fat diet. The study was published Monday in the Journal of Neurology, Neurosurgery and Psychiatry.
"We found that a Mediterranean diet with olive oil was able to reduce low-grade inflammation associated with a high risk of vascular disease and cognitive impairments," said Dr. Miguel Martinez-Gonzalez, the chairman of preventive medicine at the University of Navarra in Spain and a study author.
The Mediterranean diet is devoid of processed foods and bad fats, and high in whole grains, nuts, fruits and vegetables, legumes, fish and even red wine - all things that are high in antioxidant and anti-inflammatory compounds. These types of foods are known to help reduce vascular (circulatory) damage, inflammation and oxidative (free radical) damage in the brain. FULL POST

Boys with ADHD may be at risk for obesity later in life, according to a new study - which, if confirmed in larger studies, may have implications for the more than 4 million kids in the United States living with the disorder.
Researchers at NYU's Langone Medical Center have been following more than 200 kids for four decades. They found those who had ADHD in their early years were twice as likely to be obese at age 41. FULL POST

Although drinking alcohol is known to be a risk factor for developing breast cancer, a new study suggests that alcohol may not have any effect on whether you survive the disease. In fact, researchers found that being a moderate drinker may actually improve your chances of survival.
"The results of the study showed there was no adverse relationship between drinking patterns before diagnosis and breast cancer survival," said Polly Newcomb, director of the cancer prevention program at the Fred Hutchinson Cancer Research Center in Seattle and the lead author of the study.
"We actually found that relative to non-drinkers there were modestly improved survival rates for moderate alcohol intake."

Exposure to intimate partner violence and maternal depression before the age of 3 may increase a child's risk of developing attention deficit hyperactivity disorder (ADHD), according to a new study published in the journal JAMA Pediatrics.
Researchers at the Indiana University School of Medicine looked a population of more than 2,000 children, and found that those whose parents had reported depression or intimate partner violence were significantly more likely to suffer from ADHD as they grew older.
"It wasn't surprising, from the lens of me being a behavioral pediatrician," said Dr. Nerissa Bauer, an assistant professor of pediatrics at the IU School of Medicine and the lead study author. "I routinely encounter mental health and behavioral problems in children, and this supports my initial hunch that I was seeing an increase in that." FULL POST

Being abused as a child may increase a mother's chance of having a child with autism, according to a new study, but researchers aren't sure why.
Investigators at The Harvard School of Public Health looked at more than 50,000 women in the Nurses' Health Study II group, and found that those who reported the highest levels of abuse as children themselves were 60% more likely to have children with some type of autism-spectrum disorder.

How'd you like to get paid to lose weight? Financial incentives can help improve your odds of dropping pounds, according to a new study.
Researchers at the Mayo Clinic followed 100 Mayo employees over the course of a year as they took educational classes on how to eat healthy and lose weight.
The employees were broken up into several groups - some of which got financial incentives to shed the pounds and others that just got the classes.

Centralized record-keeping systems may help improve rates of colon cancer screening, according to a new study.
Researchers at the Group Health Cooperative, a non-profit health care and insurance system in Washington state, used electronic health records to identify and monitor almost 5,000 patients who were due for a colon cancer screening but hadn't gotten it.
One group of patients received "normal care" - reminders from their doctor during appointments. A second group received a letter in the mail encouraging them to get screened; a third group got a call from a medical assistant on top of all of that, and a fourth group got a "patient navigator" to manage the screening process.
Each additional step increased the percentage of people who got screened, from 26% in the "normal" group to 65% in the patient navigator group.

Taking folic acid before pregnancy, and through the first several weeks of pregnancy, may help reduce the risk of autism for those children, according to a new study published Tuesday in the Journal of the American Medical Association (JAMA).
Researchers in Norway looked at data from 85,000 pregnancies, and found that women who took the supplement four weeks before pregnancy, and through the eighth week of pregnancy, were 39% less likely to have children with autism.
The Norwegian study is the largest to date on the benefits of folic acid for autism prevention, and marks one of the first tangible things a woman can do to reduce her risk of giving birth to a child with the disorder. FULL POST
