A new study, presented today to a meeting of heart specialists by a 17-year-old high school student, suggests that the music-playing device can interfere with the electromagnetic equipment in implanted pacemakers.
Reuters reports 100 pacemaker patients (with a mean age of 77) were examined in the study.
Holding the iPod just two inches away from their chests for 5 to 10 seconds was enough to cause electrical interference half the time. In some cases, iShenanigans could be detected as far as 18 inches away. The interference usually just caused the equipment to misread the heart's pacing, but one case caused the pacemaker to stop working entirely.
The study, published by nine doctors including the medical officer monitoring city firefighters, Dr. David Prezant, found that firefighters and rescue workers contracted sarcoidosis in the year after Sept. 11, 2001, at a rate more than five times higher than the years before the attacks.
Food safety experts have advised parents to eliminate a series of additives from their children's diet while they await the publication of a new study that is understood to link these ingredients to behaviour problems in youngsters.
The study, published in the May 15, 2007 issue of the American Journal of Epidemiology, was designed by UNC School of Public Health researchers to measure the impact of the 9/11 terrorist attacks on military and non-military families. The researchers chose to study Texas because of the large military population there and the availability of data.
Researchers found that prior to October 2002, rate of abuse and neglect - called maltreatment - was slightly higher among non-military families compared to military families. However, after the U.S. started sending larger numbers of troops to Afghanistan and Iraq in 2003, rates of abuse and neglect in military families far outpaced the rates among non-military families. Military files indicate more troops were deployed and fewer returned home in 2003.
In addition, the rate of occurrence of substantiated maltreatment in military families was twice as high in the period after October 2002 compared with the period prior to that date. During the same period, the rate of substantiated child abuse and neglect was relatively stable for non-military families, said Danielle Rentz, Ph.D., lead author of the study, which was part of her doctoral dissertation at the UNC School of Public Health.
The study, led by Ann Louise Webber of the Queensland University of Technology in Australia, utilized Visual-Motor Control and Upper Limb Speed and Dexterity subtests of the Brunicks-Oseretsky Test of Motor Proficiency to measure fine motor skills, and perceived self esteem was assessed using the Harter Self Perception Profile for Children. Results shows that fine motor skills were significantly worse and perception of social acceptance was lower in amblyopic children. Performance on the fine motor skill tasks could not predicted by level of stereoposis or inter-ocular visual acuity difference in the amblyopic group.
