And Now for some news ….



Preoperative vitamin D deficiency common in patients undergoing spinal fusion

Researchers from St. Louis found an “alarmingly high” vitamin D abnormality rate in adults undergoing spinal fusion, according to a study presented here at the 2011 Annual Meeting of the North American Spine Society.

“The objectives of this study were to characterize the prevalence of preoperative hypovitaminosis D on adults undergoing spinal fusion — and to ascertain whether previously identified risk factors for deficiency could be applied to the spine population,” according to study author Jacob M. Buchowski, MD.

“Looking at the risk factors, patients who had vitamin D deficiency tended to be obese, they tended to be light-skinned and a large percentage of them were smokers,” Buckowski said. “Interestingly, patients with a history of revision surgery … or those with a history of fractures were not found to be statistically different from those who were not vitamin D deficient.”

Among those patients who had inadequate levels of vitamin D, the patients had higher VAS pain scores, lower bone mineral density and a higher prevalence of neurologic deficits.

Delay before herniated lumbar disc treatment yields poorer results

Patients who undergo treatment for a herniated lumbar disc are less likely to experience improvement in pain, function and satisfaction if they wait more than 6 months before seeking treatment, according to a study from researchers in Philadelphia.

The findings, published in the Journal of Bone and Joint Surgery, observed 1,192 patients older than 18 years and enrolled in the Spine Patient Outcomes Research Trial, conducted at 13 multidisciplinary spinal practices in 11 states.

The patients in the cohort received treatment for intervertebral lumbar disc herniation. Rihn and his colleagues compared patients who had symptoms for 6 months or less (927 patients) to those who had symptoms for more than 6 months (265 patients).

Whether treatment was operative or non-operative, Rihn’s team found patients had significantly worse primary outcome measures if they experienced symptoms for more than 6 months before treatment, as determined through an analysis of multiple pain, function and disability indexes.

“Patients who have had symptoms for longer than 6 months can find relief with either non-operative treatment or surgery, but they may not reap as much benefit as those who have had symptoms for 6 month or less,”

Researcher provides further evidence that slow eating reduces food intake

Two new studies by researchers at the University of Rhode Island are providing additional insights into the role that eating rate plays in the amount of food one consumes. The studies found that men eat significantly faster than women, heavier people eat faster than slimmer people, and refined grains are consumed faster than whole grains, among other findings.

In one laboratory study, which validated that self-reported eating rates reflect an individual’s actual eating rate, researchers found that fast eaters consumed about 3.1 ounces of food per minute, medium-speed eaters consumed 2.5 ounces per minute, and slow eaters consumed 2 ounces per minute. This work is the first to validate self-reported eating rates that have been used in large population studies, which have shown relationships between eating rate and body weight.

The researchers also found what researchers described as “very strong gender differences” in eating rates. At lunch, the men consumed about 80 calories per minute while the women consumed 52 calories per minute.

The second study, which examined the characteristics associated with eating rates, found a close association between eating rate and body mass index (BMI), with those individuals with a high BMI typically eating considerably faster than those with a low BMI.

While the link between eating rate and obesity is still being studied, the study’s author said that her research has demonstrated that eating slowly results in significantly fewer average calories being consumed.

“It takes time for your body to process fullness signals, so slower eating may allow time for fullness to register in the brain before you’ve eaten too much.”

An earlier study by this author found that women who were told to eat quickly consumed 646 calories in nine minutes, but the same women consumed just 579 calories in 29 minutes when encouraged to pause between bites and chew each mouthful 15 to 20 times before swallowing.
