Stress Is a Prime Suspect

1 Unemployment Linked to Heart Attack Risk

A Duke University study of more than 13,000 Americans aged 50 to 75 over an 18-year span has found that repeatedly becoming unemployed can raise one's chances of a heart attack as much as smoking, diabetes, or high blood pressure can. In the Duke study, published in the Archives of Internal Medicine, the unemployed suffered heart attacks 35 percent more often than the employed overall, even after controlling for an array of risk factors such as smoking, fitness and diet. And at the negative effect accumulated with repeated unemployment -- the first job loss only increased the risk of heart attack by 22 percent, but after four or more job losses the risk was 63 percent higher, a risk differential equal to that between smokers and nonsmokers or diabetics and non-diabetics.

And, Oh Yeah, She's Pregnant

2 Kate Middleton Hospitalized with Vomiting

Kate Middleton, whose pregnancy was formally announced today, was hospitalized with hyperemesis gravidarum, an extreme, potentially dangerous form of morning sickness. She is expected to remain in the hospital for several days. Hyperemesis gravidarum affects about one in 50 pregnant women and is more common in younger women, women pregnant for the first time and those expecting multiple births. (Let the speculation begin.) Kate’s hospital discharge will depend on how well she’s keeping fluids down, experts say, and add that women are treated with IV fluids and nutritional supplements. The condition, which is thought to be linked to hormonal changes, usually subsides by the second trimester. There are no long term effects for mother or child if the condition is recognized and treated early.

Kids Participate First Time Ever

3 Biggest Loser Tackles Childhood Obesity

"The Biggest Loser" returns in January to take on childhood obesity for the first time. The show will feature childhood obesity expert Dr. Joanna Dolgoff and Jillian Michaels, who just became a new mother. Season 14 will also have adult participants eager to lose weight, but the focus for kids will be on getting healthy. The kids will not be eligible for elimination and won't weigh in on camera, but their progress will be featured each episode. The three kids participating are 13-year-old Noah “Biingo” Gray, 16-year-old Sanjana “Sunny” Chandrasekar and 13-year-old Lindsay Bravo. Noah aspires to be a pro baseball player, while Sanjana wants to gain more self-confidence. Lindsay, who gave up cheerleading after being teased about her weight, hopes to inspire others.

The Pinocchio Effect

4 When You Lie, Your Nose Gets Hot

While the fable that your nose will grow every time you lie remains untrue, your nose does actually go through changes when you don’t tell the truth. Researchers with the University of Granada have found through studies of thermography that the temperature around the nose and in the orbital muscle (in the inner corner of the eye) rises when mental effort is being made, such as when we are performing a difficult task, being interrogated on a specific effect, or lying. When we are not truthful with our feelings, researchers found that a brain element called the insula is activated which is involved in the regulation of body temperature. Anxiety and sexual desire also causes the temperature in the face to change, detectable by the thermograph.

More Alive at Year Five

5 Metformin Benefits Ovarian Cancer Patients

Two studies have found an association between metformin and increased survival in ovarian cancer patients. The first involved 239 women on metformin for diabetes, the drug’s intended use. All of them were undergoing the same chemotherapy treatment. Five years after being diagnosed with cancer, 67 percent were still alive compared to 48 percent not on the drug. Another study with a more diverse cohort observed that 73 percent of ovarian cancer patients who took metformin were alive after five years compared to 44 percent of the control group. This was not seen with any other diabetic drug and previous research indicates metformin could be used to treat a variety of cancers. It is hypothesized that metformin alters the cancer cells’ metabolism of glucose which causes them to starve.

More Drinking, More Dopamine?

6 Gene Variant Linked to Teen Binge Drinking

Results from a study published in the Proceedings of the National Academy of Science suggest that a gene involved in dopamine release may be associated with binge drinking in teens. RASGRF-2 knockout mice did not release dopamine from neurons in the ventral tegmental area (VTA) area of the brain. Dopamine is a neurotransmitter brain cells release when we do something that feels good, also known as the “reward” system. A study in teenage boys found a RASGRF-2 variant tied to more brain activity associated with the VTA and dopamine release, and at 16, those with the variant drank alcohol more often. Alcohol abuse kills 2.5 million people around the world annually and is predicted to lead to the early deaths of 210,000 people over the next twenty years in England and Wales.
