Lower Cholesterol and BP Too

1 Get a Good Night’s Sleep for Heart Health

Chronic sleep deprivation may lead to stroke, heart attack and early death, says a new study published in the European Heart Journal. "If you sleep less than six hours per night and have disturbed sleep you stand a 48 per cent greater chance of developing or dying from heart disease and a 15 per cent greater chance of developing or dying of a stroke,” says co-author Francesco Cappuccio. The study followed up evidence from seven to 25 years from more than 470,000 participants in the US, UK, Japan and Sweden. "Chronic short sleep produces hormones and chemicals in the body which increase the risk of developing heart disease and strokes, and other conditions like high blood pressure and cholesterol, diabetes and obesity,” says co-author Dr. Michelle Miller.

Breast-Feeding May Matter

2 Obesity Increased by Solids Before Four Months

Obesity risk may be increased by feeding solid foods to formula-fed babies before 4 months, say researchers who compared obesity rates among 3-year-olds. CNN reports that researchers also found that babies who were breast-fed for at least four months didn't experience obesity related to timing of solid-food introduction. Yet, babies who were fed formula and those who didn't have four full months of breast-feeding before solids were introduced experienced a sixfold increase in risk of obesity at age 3. Study findings were published in the journal Pediatrics.

Raising a Smarter Kid

3 Processed Food Can Lower IQ of Kids

Consuming a diet high in sugars, processed foods and fats in early childhood can lower IQ, while enjoying a diet full of vitamins and nutrients can actually raise IQ, suggest UK researchers. Using participants from the Avon Longitudinal Study of Parents and Children, researchers measured IQ at age 8.5 with the Wechsler Intelligence Scale for Children. Even if diet improved after age 3, findings reveal that a predominantly processed food diet at 3 years old was associated with lower IQ at 8.5 years old. However, a healthy diet had the opposite effect. "It is possible that good nutrition during this period may encourage optimal brain growth," note the researchers. Findings are published in Journal of Epidemiology and Community Health.

Big Changes Coming

4 New Lymph Node Removal Advice for Breast Cancer

For early breast cancer patients, scientists have found that it's not always necessary to remove all armpit lymph nodes. They believe doctors can remove just one or very few lymph nodes to look for cancer and then decide on further treatment. The findings mark a big change from the long-held practice of removing the lymph nodes to prolong life. Scientists now say that removing all underarm lymph nodes doesn't improve survival or make cancer less likely to recur, reports New York Times. Women in the study who kept their lymph nodes had chemotherapy and radiation. Findings are relevant for about 40,000 women in the U.S. a year with early breast cancer who meet certain criteria. Removing lymph nodes from under the arm may cause complications like infection or chronic swelling in the arm.

Last Cig Nearly Year Ago

5 President Obama Quits Smoking

Let the uncertainty finally end: President Obama has quit smoking! Michelle Obama said today that her husband hasn't smoked in almost a year. Many will surely watch to see if the President kicked the habit for good this time. Obama also announced during his 2008 campaign that he was quitting the habit. Huffington Post reports that Mrs. Obama said that the President wanted to be able to look his daughters in the eye and say he doesn't smoke if they questioned him.

Preventing HIV Ups Other Risks

6 Babies Who Evade Mom's HIV Still at Risk of Death

Infants exposed to HIV in utero that do not contract it due to medical intervention that greatly reduces the risk of maternal transmission are four times more likely die in their first year of life from other infectious diseases. A study looking at 100 South African moms and their infants had their antibody levels compared to those of HIV-negative babies born to HIV-positive mothers. These babies, known as HIV-exposed infants, had lower antibody levels to whooping cough, tetanus and pneumococcus infections and were also more likely to get upper respiratory infections and meningitis. They believe the immune response may be altered in these babies and feel this study demonstrates the need for increasing vaccinations in impoverished parts of the world.
