Alarming and Dangerous, Say Docs

1 Embedding Behavior on Rise among Troubled Teens

Doctors say self-injury among troubled teens who embed objects such as staples and paper clips in their bodies is on the rise. "Children tell us that the physical pain is easier to deal with than emotional pain. And self-embedding behavior distracts them from the emotional pain." says Dr William E. Shiels, Nationwide Children's Hosp, and the author of a new study on self-embedding behavior. Shiels told CBS News that 1 in 4 of all teens - not just those who are troubled - engages in some form of self-injury including embedding, burning or cutting. Embedders often respond to drug and/or psychotherapy, says Shiels who encourages caregivers to consider self-embedding in teens with unexplained sores or skin infections and who cover themselves in excess clothing even in warm weather.

Antiretroviral Drugs Key

2 Early Treatment Can Prevent Spread of HIV

Those with HIV are less likely to give the infection to a sexual partner if they start medication immediately, reports CNN. A new international study revealed that antiretroviral (ARV) drugs taken early led to a 96.3 percent reduction of HIV transmission to a uninfected sexual partner. ARV drugs are most effective at reducing transmission of HIV when started before the immune system has become weakened. The HPTN 052 study, which was scheduled to end in 2015, is funded by the National Institutes of Health. CNN reports that the study findings were released early due to the "clarity of the findings."

But Obesity Is Costlier

3 School Switch to Healthy Foods Will Be Costly

In December, the government passed legislation which gives the USDA the power to set and improve the nutritional standards for food provided to school children. Among the changes include establishing calorie maximums, reducing sodium and starchy vegetables, and eliminating trans fatty acids. While health experts applaud the new efforts, some school districts will be financially challenged by the changes. Fresher, less processed foods tend to be more expensive. Many districts have made improvements to their menus over the past several years, including whole grain pizza crusts and whole-muscle chicken tenders. But, with obesity now affecting nearly one of every five American children over the age of 6, “it’s worth the additional money.”

Addiction Vs. Aversion

4 Receptor's Genes Linked to Nicotine Addiction

New research further demonstrates that nicotine addiction has a genetic component that is related to the acetylcholine receptor expressed in an area of the midbrain called the habenula. Three genes encode for this receptor and researchers focused on two of them; alpha5 and beta4. Previous research has shown that a significant percentage of heavy smokers have a mutation in this gene which makes it harder to quit and increases the risk of developing lung cancer. Beta4 was overexpressed in mice which made them averse to nicotine in their water. The mutated alpha5 gene was put in the habenula of these transgenic mice which quickly increased their preference for nicotine. Researchers believe the expression of these two genes have to strike a balance to control nicotine consumption.
