Adult Violence Is Likely Too

1 Childhood Bullying Tied to Adult Antisocial Traits

Adults who were bullies as children are more likely to be antisocial, lie and have a tendency towards violent behavior, finds a new study. Some highlights: Adults with a history of bullying were 10 times more likely to lie than those who didn’t bully; they were six times more likely to get into fights and more than twice as likely to harass or threaten others. The study also finds that conduct disorder, a personality disorder common to childhood bullies, is a precursor to adult behavior problems. Researchers explained why bullies tend to hang out with one another. Said Matt Delisi, "Because bullies are so aggressive, they are viewed by peers to be difficult to deal with, so they are rejected" and hang out with other rejected kids with similar personality traits.

Not a Cure, but Helpful

2 Human Growth Hormone as a Tool for Cystic Fibrosis

Researchers say they still haven’t found a cure, but a recent study from the University of Connecticut shows that human growth hormone (HGH) can reduce the time patients with cystic fibrosis spend in hospitals. Case studies showed that HGH added 1.25 inches in height, three pounds in weight, larger internal organs, and an improvement in the mineral content of bones. According to C. Michael White, lead author of the study, annual hospitalizations were decreased by half. Cystic Fibrosis affects 30,000 people in the U.S. and involves various organs, including the lungs and pancreas. While the study, funded by the U.S. Department of Health and Human Services, provides insight into managing the disease, there’s not enough evidence to indicate that HGH could extend lives.

Momma Can Drink a Little

3 One or Two Drinks a Week While Pregnant OK

Having up to two drinks per week while pregnant doesn't increase the risks of behavioral or cognitive problems in children, say British researchers who used data from 11,513 children in the U.K. Millennium Cohort Study. Children in the study were followed by researchers for five years after birth with behavior assessments and cognitive tests, reports MSNBC. Despite these findings, it's important to note that heavy drinking during pregnancy has been shown to harm the fetus. Research findings were published in the Journal of Epidemiology and Community Health, a publication from the British Medical Journal.

Americans Not the Longest Lived

4 Life Expectancy of Americans Still Lagging

The life expectancy of Americans continues to lag behind other countries, finds a Commonwealth Fund-supported study. The U.S. can't seem to gain as many years as other countries when it comes to life expectancy. Obesity, smoking, traffic deaths and homicides are all to blame, say researchers. Over the past 30 years in the U.S., fifteen-year survival rates for both men and women 45 to 65 years old fell relative to the other 12 ranked countries, including Australia, Austria, Belgium, Canada, France, Germany, Italy, Japan, the Netherlands, Sweden, Switzerland and the United Kingdom. The U.S. ranking for 15-year life expectancy for men aged 45 fell from third in 1975 to twelfth in 2005. White women aged 45 years fared the worst in life expectancy, lagging behind all other ranked countries.

Protein That Increases BP Higher

5 Key Mechanism Behind Pre-Eclampsia Discovered

Researchers have discovered how Pre-eclampsia occurs, allowing for the development of more effective anti-hypertensive drugs. They looked at levels of a protein called angiotensinogen, which when oxidized, interacts with the enzyme rennin to release angiotensin, which increases blood pressure. The study showed that the oxidized, or activated, form of angiotensinogen was higher in women with pre-eclampsia than women without it. There are drugs that lower blood pressure by inhibiting angiotensin production called ACE inhibitors and ones that block angiotensin from binding to receptors in the body, but they cannot be given to pregnant women. Pre-eclampsia is life-threatening to both mother and baby and can lead to subsequent health problems for both down the road.

One Protein, Two Diseases

6 Protein Linked to Osteoporosis and Breast Cancer

A protein initially discovered in bone is also present in breast cells and appears to be related to both osteoporosis and breast cancer. Previous research has shown that RANKL turns on the cells that break down bone when it needs to be replaced, but if too much is expressed and the bone cannot be replaced, osteoporosis results. A recent study found that HRT and the pill trigger RANKL in breast cancer by preventing mammary cells from dying when they should, and allowing stem cells to renew themselves. When the protein was inhibited in mice they developed fewer tumors. A monoclonal antibody, denosumab, was just approved in the U.S. and Europe for osteoporosis works by inhibiting RANKL and is being looked at as a possible treatment for women whose breast cancer has metastasized to bone.
