The Brain on Smoke

1 Secondhand Smoke Affects Mental Health of Kids

Kids exposed to secondhand smoke may have poorer mental health, finds a British study involving 901 kids. The new study, from University College London, reveals that the more secondhand smoke kids were exposed to, the worse their mental health, a finding particularly true for hyperactivity or "bad" behavior, reports MSNBC. For the study, researchers gauged secondhand smoke exposure through saliva tests and had parents fill out questionnaires about their kids' social, behavioral or emotional problems. The association between secondhand smoke exposure and mental health persisted even when researchers controlled for other factors that may affect mental health, such as family income, housing or asthma. Findings are published in Archives of Pediatrics and Adolescent Medicine.

Lower Breast Cancer Risk

2 Estrogen Protects Some from Breast Cancer

Women who've had hysterectomies and take estrogen pills for menopause treatment may have a lower risk of breast cancer. A new analysis of data from the Women's Health Initiative showed a statistically significant lower breast cancer risk among the women taking estrogen who did not have a family history of breast cancer, reports New York Times. However, the finding only applies to women who've had hysterectomies. A woman with her uterus should take combination estrogen and progestin to prevent uterine cancer, which is a risk when taking estrogen only pills. The new study findings were released last week at the San Antonio Breast Cancer Symposium.

Preparing for Flu Season

3 Deaths from H1N1 in Britain

H1N1 has returned to claim 10 lives in Britain in the last six weeks, reports MSNBC. Around the world, the H1N1 flu virus, also known as swine flu, killed around 18,450 people during the pandemic that started in March of 2009. The World Health Organization (WHO) has said that the H1N1 pandemic ended in August. In Britain, recent deaths from H1N1 occurred in adults under 65 years old with underlying health issues. Meanwhile in the U.S., National Influenza Vaccination Week (NIVW) has just ended. According to the CDC, NIVW is a "national observance that was established to highlight the importance of continuing influenza vaccination, as well as fostering greater use of flu vaccine after the holiday season into January and beyond."

Fish Versus Carrots

4 Protect Your Eyes by Eating More Seafood

Eating more fish and shellfish rich in omega-3 fatty acids appears to slow progression of advanced macular degeneration, a common cause of age-related blindness. Researchers from the Wilmer Eye Institute at Johns Hopkins School of Medicine studied the diet habits of 2,390 people on Maryland’s Eastern Shore. Those who had the highest weekly intake of fish such as oysters, crabs, and tuna were significantly less likely to have advanced disease, said study author Bonnielin Swenor. Although the researchers theorize that the positive effects are from omega-3 fatty acids, as suggested from previous studies, they say that it is important to keep in mind that there may be other factors, including lifestyle habits that affect eye health, such as not smoking and controlling blood pressure.

Nine Months Strong

5 President Obama May Have Finally Quit Smoking

"Congratulations President Obama! I am quitting too. Yes we can! "
- Tiffany Delite in the comments

According to White House press secretary Robert Gibbs, President Barack Obama may have finally kicked his thirty-year smoking habit. Gibbs tells the Washington Post that he “has not seen or witnessed evidence of any smoking in probably nine months.” He states that the President is fit and healthy in almost every way, including exercising six days a week and eating right. Obama’s doctors last year considered him to be in excellent health despite an elevated cholesterol level they attributed to a penchant for sweets. Despite being under considerable stress, Gibbs believes that Obama has conquered his habit due to stubbornness, hard work, chewing gum and having a support system, as his wife encourages him to abstain and his golfing buddy has also quit.

Stops Metastasis to Bone

6 Pomegranate Juice May Inhibit Prostate Cancer

Pomegranate juice has been shown to be promising particularly in the prevention of heart disease. The latest research from the University of California, Riverside shows that it may also be beneficial in inhibiting the movement of cancer cells and weakening the chemical signal that promotes metastasis of prostate cancer to bone. In a study presented at the annual meeting of the American Society for Cell Biology, two graduate students applied pomegranate juice to prostate cancer cells cultured in a lab to be resistant to testosterone. The treated cells showed increased adhesion, meaning they were less likely to break away. The researchers also identified groups of juice components that were most beneficial: phenylpropanoids, hydrobenzoic acids, flavones, and conjugated fatty acids.

Could Lead to Better Treatments

7 Genes That Confer HIV Drug Resistance Studied

It is well known that human immunodeficiency virus (HIV), the virus that leads to AIDS, mutates at an incredibly high rate which makes drug resistance a major problem. But biomedical engineer Stephanie Willerth from the University of Victoria was able to utilize a technique that allowed her to make millions of copies of the virus so she could then look at specific genes that are resistant to the antiretroviral drugs used to treat HIV. With this technique, 15,000 versions were able to be studied, a first in the history of HIV research. Knowing which genes lead to resistance could ultimately lead to the development of better treatments.
