Does Exercise Make Kids Smarter?
In the midst of reports of schools cutting recess and physical education in order to provide additional time for standardized test preparation, new research reveals that limiting physical activity may reduce cognitive function in youngsters.
The research team from the University of Illinois presented their findings this week at the annual meeting of the Society for Psychophysiological Research in Santa Fe, New Mexico.
"We have found a strong relationship between academic achievement and fitness scores," elucidates study co-author Darla Castelli. "Those who scored well in academics also did well in physical fitness. We`re not suggesting that if we run more laps it will make us smarter, but there does appear to be a correlation."
Along with researchers Charles Hillman and Sarah Buck, Castelli analyzed about 500 third, fourth, and fifth-graders. They compared the subjects` aerobic capacity, flexibility, muscle fitness and cognitive function (as determined by standard achievement tests and neuroelectric and behavioral responses to stimulus discrimination tasks).
"We found that fit children allocated more resources towards identifying stimuli, and also processed stimuli faster," Hillman pronounced. "Behaviorally, these effects showed up in that these fit children made fewer errors than sedentary ones."
"Despite increased incidence of childhood obesity and type II diabetes mellitus, physical education time is being reduced to address academic issues related to federal `No Child Left Behind` legislation," adds Castelli. "If evidence existed that physical education contributed to intellectual development, it may gain credibility and instructional time."

SOFT DRINK CONSUMPTION SKYROCKETING
Researchers at the University of North Carolina at Chapel Hill have calculated that calorie intake from soft drinks in the United States rose 135% between 1977 and 2001. Over the same span milk intake plummeted 38%.
"There has been considerable controversy about the promotion of soft drinks in schools and elsewhere," notes study author Dr. Barry M. Popkin. "Extensive research on all age groups has shown that consuming these soft drinks and fruit drinks increases weight gain in children and adults."

CHRONIC BACK PAIN EATS AWAY AT BRAIN
Scientists in Chicago have discovered new clues into what role the brain plays in chronic back pain (CBP).
The investigators used magnetic resonance imaging brain scans to compare the morphology of 26 individuals with CBP with 26 pain-free control subjects.
According to the report "patients with CBP showed 5 -11% less neocortical gray matter volume than control subjects. The magnitude of this decrease is equivalent to the gray matter volume lost in 10-20 years of normal aging. The decreased volume was related to pain duration, indicating a 1.3 cm(3) loss of gray matter for every year of chronic pain."
The study also showed that CBP patients had decreased gray matter density.
"Our results imply that CBP is accompanied by brain atrophy and suggest that the pathophysiology of chronic pain includes thalamocortical processes," conclude the authors.

EARLY RECOVERY FROM LOWER BACK PAIN PREDICTS LONG-TERM OUTCOME
What demographic factors affect a chiropractic patient`s recovery from chronic low-back pain (LBP). To find out, 115 chiropractors in Norway pooled dataon 875 patients. All patients had suffered LBP for at least 2 weeks at the time of their initial chiropractic consultation and a minimum of 30 days altogether during the preceding year.
According to the report, gender, social benefit, severity of pain, duration of continuous pain at first consultation and additional neck pain all influenced outcome at the fourth visit and at 3 months.
Early recovery was identified as a strong predictor of long-term outcome. Specifically, being free of back pain at the fourth visit was associated with triple the odds of remaining pain-free at 3 and 12 months.

MAINTENANCE CHIROPRACTIC CARE PREVENTS RELAPSE IN DISABILITY, STUDY SUGGESTS
Maintenance care appears to accomplish exactly what chiropractors have long claimed it does. According to a new study, maintenance care prevents chronic disability in patients with low-back pain (LBP).
Investigators tracked 2 groups of 15 patients with chronic nonspecific LBP. Both groups underwent intensive chiropractic care for a 1-month period. One group received no maintenance care while the other received adjustments every 3 weeks. Nine months later both groups were reevaluated.
The study`s authors write that "for both groups, the pain and disability levels decreased after the intensive phase of treatments. Both groups maintained their pain scores at levels similar to the post-intensive treatments throughout the follow-up period. For the disability scores, however, only the group that was given spinal manipulations during the follow-up period maintained their post-intensive treatment scores. The disability scores of the other group went back to their pretreatment levels."
"This experiment suggests that maintenance spinal manipulations after intensive manipulative care may be beneficial to patients to maintain subjective post-intensive treatment disability levels. Future studies, however, are needed to confirm the finding in a larger group of patients with chronic low-back pain."

Medicating Kids For Convenience
Investigators in Australia are concerned over the use of over-the-counter (OTC) medications in children.
In-depth interviews with 40 parents of children under 5 years of age showed that "there were 3 striking and readily apparent themes in the use of OTC medications among children. One was the administration of OTC medications as a form of`social medication to give parents control over children`s behavior that they perceived as fractious and irritating. A related theme was the use of OTC medications to reduce the inconvenience to the parents of having a sick child, again giving parents greater control and better time-management abilities. Finally, acetaminophen was considered by many parents to have almost miraculous properties in calming, sedating and lifting the mood of children."
"The use of OTC medications for the treatment of minor ailments among children is widespread, despite the lack of evidence of efficacy of the most commonly used medications and the potential for toxicity," conclude the scientists. "With the increasing propensity to look to medication as a means of supporting changing lifestyles, there is an urgent need to review the prevalence and effects of social medication."

Latest Research CHRONIC PAIN
"Vast majorities of people suffering from chronic pain are actually the result of unnecessary back surgery. In one study, I demonstrated that at least 80% of those who had lumbar surgery for a presumed ruptured disc had not had a ruptured disc before their first surgery. (Shealy CN. Percutaneous radiofrequency denervation of spinal facets.
Treatment for chronic back pain and sciatica. J of Neurosurgery.1975;43:448-451.) By the time they had between 5 and 7 unsuccessful back operations they certainly were invalids....In selective patients with back pain, we have found two significant problems: locked or degenerative facet joints or a sacral shear."

CHRONIC BACK PAIN IMPAIRS DECISION MAKING
Scientific evidence supports the hypothesis that chronic pain impairs an individual`s decision-making capability
As part of one study, investigators compared 26 healthy people with 26 patients with chronic back pain (CBP) and 12 patients with a condition called chronic complex regional pain syndrome (CRPS). CRPS is a chronic nerve disorder typically afflicting the arms or legs, which usually onsets following an injury.
The study participants were asked to perform a test researchers use to assess emotional decision-making. The test, called the Iowa Gambling Task, is a gambling card game.
Subjects with CBP performed 41% worse than did pain-free individuals. Those with CRPS performed even poorer.
The study`s authors conclude that "our evidence indicates that chronic pain is associated with a specific cognitive deficit, which may impact everyday behavior especially in risky, emotionally laden, situations."
"Other cognitive abilities, such as attention, short-term memory, and general intelligence tested normal in the chronic pain patients."

OPTIMISTS LIVE LONGER
A sunny disposition may be the key to long life, finds a study suggesting that optimists live longer than their less positive peers.
According to a 9-year inquiry of 941 adults in the Netherlands between the ages of 65 and 85 years, the most optimistic participants were 29% less likely to die during the study period than the most pessimistic of subjects.
Subjects who had an upbeat take on life were 77% less likely to die of cardiovascular disease than were pessimists. These findings were not influenced after researchers controlled for confounding issues such as age and lifestyle factors.

COMMON SUBLUXATION PATTERN IDENTIFIEDIN 96% OF CHILDREN
A new study examines a subluxation pattern common in children called the Pelvic Distortion Subluxation Complex (PDSC). The study`s researchers believe that PDSC "is responsible, partially or fully, for a number of adaptive neurological patterns and kinesiopathological reflexes that can propagate a myriad of conditions."
To test their hypothesis, 6 chiropractors with pediatric certification from the International Chiropractic Pediatric Association examined 327 boys and 323 girls.
The study`s authors explain that "the preponderance of PDSC is to present with a left pelvic fixation and a corresponding right hyper mobility. We have found that 96% of all children seem to possess, and be subjected to the effects of the Pelvic Distortion Subluxation Complex. The PDSC was a common denominator in complaints plaguing our sample of children. These are summarized into a percentage of the total sample and the most common complaintsof children in our study are mainly of a somatic nature with some visceral and immune components."
"Our study revealed a pattern of pelvic dysfunction correlated with numerous somatic, visceral and immune complaints. These dysfunction`s should be discovered as early as possible in a child`s development to effect a correction and the relationship between these dysfunction`s and ill health should be further studied."

According to Dr. Guylaine Lanctot, MD:
The bottom line is that the medical systems are controlled by financiers in order to serve financiers. Since you cannot serve people unless they get sick, the whole medical system is designed to make people sicker and sicker.
"It is now evident that the American medical system is the leading cause of death and injury in the US." Dr. Joseph Mercola
This fully referenced report shows the number of people having in-hospital, adverse reactions to prescribed drugs to be 2.2 million per year. The number of unnecessary antibiotics prescribed annually for viral infections is 20 million per year. The number of unnecessary medical and surgical procedures performed annually is 7.5 million per year. The number of people exposed to unnecessary hospitalization annually is 8.9 million per year. The most stunning statistic, however, is that the total number of deaths caused by conventional medicine is an astounding 783,936 per year.
