Depression High Among Youth Victims of School Cyber Bullying, NIH Researchers Report

Unlike traditional forms of bullying, youth who are the targets of cyber bullying at school are at greater risk for depression than are the youth who bully them, according to a survey conducted by researchers at the National Institutes of Health.

The new finding is in contrast to earlier studies of traditional bullying, which found that the highest depression scores were reported by another category of youth involved in bullying-bully victims. Past studies on traditional bullying show that bully-victims — those who both bully others and are bullied themselves — are more likely to report feelings of depression than are other groups.

Traditional forms of bullying involve physical violence, verbal taunts, or social exclusion. Cyber bullying, or electronic aggression, involves aggressive behaviors communicated over a computer or a cell phone.

Animal Research: Animal Welfare vs. Animal Rights

Essentially every major medical advance in the last century — from antibiotics to analgesics such as Tylenol or Motrin, from blood transfusions to organ transplantation, from vaccinations to chemotherapy, bypass surgery and joint replacement — is based on knowledge obtained through research with animals. In fact, almost 75% of all Nobel Prizes in Medicine awarded since 1901 were won for discoveries that required the use of animals [1].

Indeed, animal-based research has contributed to a significant improvement in the quality and length of human life. From cancer to heart disease and stroke to diabetes, society benefits from the use of laboratory animals in biomedical research [2]. Unfortunately, there is a worldwide movement that seeks to halt those advances and establish moral and legal equality between humans and animals, to eliminate the status of animals as property (meaning domestic pets and livestock for food), and to stop the use of animals in biomedical research.

The debate between those who support animal research and those that don’t often gets portrayed in such a way that it appears that one group cares about animals while the other group doesn’t. This isn’t the case at all — fundamentally, the issue is how to reduce the total suffering for both humans and animals.

Highlight HEALTH 2.0 Interview: Bertalan Mesko

In 2006, Bertalan Mesko (Berci) started Scienceroll, a blog about genetics and popular medicine. It quickly evolved into a leading source of information following the impact of Web 2.0 on medical education and healthcare. He posts regularly on Twitter (@Berci) about health 2.0, medicine 2.0 and personalized medicine (top five words: rt, ff, medicine, medical, health), and maintains two “microcarnivals” on FriendFeed: Gene Genie and Medicine 2.0.

Over the past four years, Berci has accomplished many things. In 2009, he started a Ph.D. in clinical genomics after graduating with an M.D. from the University of Debrecen in Hungary. From his work at Scienceroll, he has been invited to lecture on medicine in the Web 2.0 era at several clinics and departments at the University of Debrecen, and has presented at several medical conferences around the world.

In 2008, Berci launched the first university credit course for medical students that focuses on Web 2.0 and medicine (med20course.wordpress.com). He also founded Webicina.com, the world’s first medical Web 2.0 guidance service. Webicina aims to ease the work of physicians and scientists by recommending useful tools and sites and by presenting them the new world of Web 2.0. Just last week, Webicina launched its 65th medical topic spanning 15 languages on medicine.

I’ve known Berci Mesko since 2006 and we recently had a chance to talk about Scienceroll, Webicina and his professional path in the Web 2.0 era.

Hair Cortisol as a Predictive Biomarker for Heart Attack

We all deal with stress. Whether it’s stress from a job, financial, or relationship issues, chronic stress has been linked to an increased risk for developing cardiovascular disease [1-2]. However, there hasn’t been a biological marker that could be used to measure an individual’s level of stress. A recent study performed by researchers at the University of Western Ontario Schulich School of Medicine & Dentistry and published in the journal Stress has found that the level of cortisol in hair can be used as a biomarker to measure chronic stress and the risk of heart attack in men [3].

NIH Expands Network Focused On How Genes Affect Drug Responses

The National Institutes of Health plans to spend $161.3 million over the next five years to expand the Pharmacogenomics Research Network (PGRN), a nationwide collaborative of scientists focused on understanding how genes affect a person’s response to medicines.

“Thanks to breakthroughs in genome sequencing technologies and our growing understanding of genetic variation among individuals, there has never been a better time to propel the field of pharmacogenomics,” said NIH Director Francis S. Collins, M.D., Ph.D. “Through these studies, we are moving closer to the goal of using genetic information to help prescribe the safest, most effective medicine for each patient.”
