Nutritional authorities encourage consumers to include calcium-rich foods in their daily diets. However, consumer purchases are driven not only by health considerations and dietary preferences, but also by cost. This study assessed the cost of calcium from a wide variety of food sources, as well as supplements, based on retail prices in Seattle, San Francisco, Raleigh, NewYork City, and Washington, D.C., while controlling for seasonal variation. Costs were adjusted based on calcium absorption fractions. Calcium carbonate supplements emerged as the least expensive source of calcium, at roughly one-third the cost of the least expensive food source of calcium. The least expensive food sources of calcium were Total cereal, skim milk, and calcium-fortified orange juice from frozen concentrate. This information is useful for dietitians, health professionals, and consumers in meeting calcium requirements on a budget.

Selecting and evaluating appropriate treatments for children with cerebral palsy has been challenging. One difficulty is in the ability to quantify the presence and importance of coexisting motor signs. This study presents quantitative measures developed to assess spasticity and dystonia. Children diagnosed with extrapyramidal or spastic cerebral palsy and matched control children were studied. Spasticity was measured as the slope of the force-velocity relationship from a test where we measured the forces required to passively extend the elbow at different velocities. Dystonia was assessed by measuring "overflow" movements of arm during active movement of the other arm. Measures of dystonia and spasticity did not correlate with one another, but did correlate with their respective clinical measurement tools, the Modified Ashworth scale and the Barry-Albright Dystonia scale. Most children had a combination of both spasticity and dystonia, despite diagnosis. Our measures also related to different aspects of reaching: children with increased dystonia made more curved paths, and children with increased spasticity hit higher peak velocities. These measurements allow us to distinguish between different motor disorders and the degree to which each contributes to reaching performance. Use of quantitative measures should improve selection and evaluation of treatments for childhood motor disorders.

Can spasticity and dystonia be independently measured in cerebral palsy?

Oocyte vitrification has the potential to expand tremendously the reproductive options for women desiring fertility preservation. Indeed, the number of publications regarding the reliability and efficiency of oocyte vitrification has increased exponentially over the past decade. The application of the technique to standard reproductive technologies depends on not only oocyte survival, but also the developmental potential and clinical outcomes from the resultant embryos. The aim of this study, therefore, was to examine the embryo quality obtained from vitrified, warmed oocytes in a standard infertility population. The results demonstrate that high quality blastocyst development can be expected with subsequent excellent obstetric and perinatal outcomes. These data support oocyte vitrification as a promising technique for fertility preservation.

With progressive abnormalities in leg strength, tone, and sensation, adrenomyeloneuropathy (AMN) is a differential diagnosis for multiple sclerosis and hereditary spastic paraparesis. AMN pathology has been linked to weakness, making it a relevant model to evaluate the relationship between neurodegeneration and disability. Quantifying symptom severity in AMN is essential for treatment development in rehabilitative management.

Physical therapy intervention is the primary treatment for gait ataxia and imbalance in individuals with cerebellar damage. Our aim was to determine if a home balance exercise program is feasible for improving locomotor and balance abilities in these individuals.
