Lots of TV and Web harms kids??™ health

04.12.2008
Spending a lot of time watching TV, playing video games and surfing the Web makes children more prone to a range of health problems including obesity and smoking, U.S. researchers said on Tuesday. U.S. National Institutes of Health, Yale University and the California Pacific Medical Center experts analyzed 173 studies done since 1980 in one of the most comprehensive assessments to date on how exposure to media sources impacts the physical health of children and adolescents. The studies, most conducted in the United States, largely focused on television, but some looked at video games, films, music, and computer and Internet use. Three quarters of them found that increased media viewing was associated with negative health outcomes. »»»

Pediatric Obesity May Alter Thyroid Function and Structure

04.12.2008
In addition to its strong associations with hypertension, cardiovascular disease, and diabetes, pediatric obesity may induce alterations in thyroid function and structure, according to a new study accepted for publication in The Endocrine Society??™s Journal of Clinical Endocrinology & Metabolism (JCEM). Thyroid hormones drive metabolism, however demonstration of a direct or strong correlation of obesity with deficient thyroid function has been controversial, and previous studies provide conflicting conclusions. While some studies have found that thyroid disorders may lead to obesity, this recent study shows that in some cases, it is the obesity that may cause the disorder. ???Our study shows that alterations in thyroid function and structure are common in obese children and we may have uncovered the link,??? said Giorgio Radetti, M.D., of the Regional Hospital of Bolzano in Italy and lead author of the study. ???We found an association between body mass index and thyroid hormone levels which suggests that fat excess may have a role in thyroid tissue modification.??? »»»

Hypersensitivity Reactions to the Quadrivalent HPV Vaccine Are Rare

04.12.2008
Hypersensitivity reactions to the quadrivalent HPV vaccine (4vHPV, Gardasil) are uncommon and most schoolgirls can tolerate subsequent doses, finds the first evaluation of the quadrivalent HPV vaccine published on bmj.com today. In Australia, from April 2007, all females aged 12??“26 years received the 4vHPV vaccine as part of a national secondary school immunisation programme. Some components of the vaccine such as aluminium salts and yeast have previously been associated with hypersensitivity reactions. Reports of some adverse events followed the school vaccination programme. Dr Sharon Choo and colleagues from Australia describe the results of clinical evaluation, skin tests, and vaccine challenge in 25 schoolgirls with suspected hypersensitivity to 4vHPV after more than 380,000 vaccine doses were administered in schools in Victoria and South Australia. »»»

Cellular senescence a double-edged sword

04.12.2008
(DOE/Lawrence Berkeley National Laboratory) Scientists have shown that cellular senescence, the process by which biological cells stop dividing in response to stress or damage to their DNA, triggers the secretion of proteins that cause inflammation in neighboring cells and tissue. Inflammation is linked to almost every major disease associated with aging, including many cancers. »»»

Genes determine whether sugar pills work

04.12.2008
(Uppsala University) It is a well-known fact in drug trials that individuals can respond just as well to placebos, sugar pills, as to the active drug. On the other hand, it is difficult to explain why only certain people get better from placebos. A team of researchers from Uppsala University and Gothenburg University have now found gene variants that can impact the placebo effect and a mechanism in the brain that characterizes those who respond to placebos. »»»
