Minority children are far less likely than their white counterparts to be diagnosed with attention deficit hyperactivity disorder (ADHD), according to a new study in this week's journal Pediatrics.
In fact, authors found that African-American children were 69% less likely to be diagnosed, while Hispanic children were 45% less likely to have an ADHD diagnosis.
More than 5 million children in the United States have been diagnosed with ADHD, according to the Centers for Disease Control. In fact, it's the most commonly diagnosed mental health disorder in U.S. children. A diagnosis can help kids get the proper treatment and medication they need, and early intervention can be key in helping a child learn.

You've probably heard that eating multiple small meals throughout the day is a good way to stave off hunger and keep your metabolism revved up while trying to lose weight. But a new study could change your diet strategy.
Eating two large meals early and skipping dinner may lead to more weight loss than eating six smaller meals throughout the day, research presented at the American Diabetes Association Scientific Sessions conference this week in Chicago suggests.
"Both experimental and human studies strongly support the positive effects of intermittent fasting," lead study author Dr. Hana Kahleova told CNN in an e-mail.

The H7N9 bird flu virus, first identified in humans earlier this year, kills about 36% of infected people admitted to hospitals in China, according to a new report published Sunday in the British medical journal The Lancet.
Far more difficult to estimate, according to the study, is how many die in the general population after becoming infected, as the most severe cases are also more likely to lead to hospitalization.
That estimate – a 0.16% to 2.8% overall fatality rate for those showing symptoms of infection – suggests that the H7N9 virus is less deadly than the H5N1 Bird Flu first appearing in 2003, and more deadly than the 2009 H1N1 swine flu pandemic. FULL POST

A group of international researchers announced Thursday that they have created a three-dimensional model of the human brain in unprecedented resolution. It's called BigBrain.
"BigBrain is the first ever brain model in 3-D, which really presents a realistic human brain with all the cells and all the structures of a human brain," said Karl Zilles, senior professor of the Julich Aachen Research Alliance, in a press briefing. The research is being published in the journal Science.
This model is akin to a scaffold into which information about the living brain can be inserted. It's a reference to provide framework for research in many directions, such as how the brain is organized.

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

It seems we often hear of another patient who has been desperately waiting for a transplant that could save his or her life.
Earlier this month it was a 10-year-old girl in Pennsylvania hoping for a new set of lungs. Before that it was Molly Pearce, who needs four organ transplants to survive. In September a man walked the streets of his South Carolina town asking strangers for a kidney for his wife.
More than 118,000 people in the United States are currently awaiting organ donations, according to OrganDonor.gov; 18 of them die each day without a donation.
Facebook co-founder Mark Zuckerberg is hoping to change that with the power of the world’s largest social networking site. On May 1, 2012, Facebook launched an initiative aimed at encouraging more people to register as organ donors.

Don't drink while you're pregnant, not even in moderation. It's wisdom that major medical groups such as the American College of Obstetricians and Gynecologists have repeatedly emphasized. But researchers are still looking into the specific effects of different quantities of maternal drinking on children.
A new study in BMJ is the latest to look at whether moderate drinking during pregnancy is associated with adverse effects on children. The researcher's measure for detrimental fetal neurodevelopment - children's ability to do various balance tasks at age 10.
Researchers found that mothers who drank between three and seven glasses of alcohol a week during pregnancy did not, on average, have children who had balance problems at age 10, and there were even some observed benefits. However, these are associations, not a proof that alcohol causes any outcomes.

Scientists may be able to predict throat cancers caused by the human papillomavirus (HPV) more than 10 years before patients get diagnosed, according to research published in the Journal of Clinical Oncology.
Using a blood test that is still in the research stage, experts were able to detect blood markers indicating early signs of the disease.
Actor Michael Douglas recently made headlines when The Guardian reported he said his throat cancer may have been caused in part by HPV transmitted through oral sex. Douglas later said he simply was stating that oral sex can lead to cancer.
HPV: What you need to know
HPV is the most common type of sexually transmitted virus in the United States and is passed on through sexual contact – genital or oral. There are more than 40 types of HPV, according to the Centers for Disease Control and Prevention, and nearly all sexually active men and women will get at least one type of HPV during their lifetime.

Cities including New York, Toronto, and San Francisco have launched public awareness campaigns to promote vaccination, but the authors also call on physicians to assess the risk to their patients and discuss the strain.
Since August 2010, 22 cases have been reported in New York City among men who have sex with men. More than half of those were already HIV positive. Seven men died. In fact, in New York City last year, men who have sex with men were 50 times more likely than the general population to be infected with the virus, according to city health officials.

African-American and Hispanic children are far less likely to be seen by specialists - for autism, but also other medical conditions - and also less likely to receive specialized medical tests than their white peers, according to a new study published Monday in the journal Pediatrics.
Dr. Sarahbeth Broder-Fingert and colleagues studied the records of 3,615 children with autism at the Massachusetts General Hospital, specifically looking at the rates of both referral to specialists and medical tests undertaken. They discovered that children from African-American and Hispanic families were far less likely to receive specialized care or specific medical tests such as a sleep study, colonoscopy, or endoscopy.
When compared to their white peers, African-American children were three times less likely to see a gastroenterologist or nutritionist, and half as likely to see a neurologist or mental health specialist, according to the study. The story is similar among children from Hispanic families.
