- STUDY DESIGN: A randomized controlled trial was performed. OBJECTIVES: To evaluate how 2 different treatment options affect perception of health, pain, and physical functioning over time among children and adolescents with low back pain (LBP). SUMMARY OF BACKGROUND DATA: LBP among children and adolescents has increased. The literature shows that children with LBP also suffer from this condition as adults. Thus, it is important to prevent and treat LBP in children and adolescents. METHODS: Forty-five children and adolescents were consecutively randomized into one of 2 treatment groups and were studied for 12 weeks. Group 1 was given individualized physical therapy and exercise and a standardized self-training program and back education. Group 2 was given self-training program and back education but no individualized therapy. The children and adolescents were tested before and after the treatment period. Child Health Questionnaire Child Form 87, Roland & Morris Disability Questionnaire, Painometer, Back Saver Sit and Reach, and test of trunk muscle endurance were used to evaluate the interventions. RESULTS: Both groups improved statistically significant in most parameters over time. On comparison between the groups the physical function measured by Roland & Morris Disability Questionnaire and the duration of pain measured by Painometer improved statistically significant in Group 1. CONCLUSION: An individual assessment by a knowledgeable physiotherapist and an active treatment model improve how children and adolescents experience their back problems with respect to health and physical function, pain, strength, and mobility, regardless of whether treatment consists of a home exercise program with follow-up or home exercise combined with exercise and treatment supervised by a physiotherapist.

- It is of great clinical value to identify subjects at a high risk of developing AD. We previously found that the amyloid positron emission tomography (PET) tracer PIB showed a robust difference in retention in the brain between AD patients and healthy controls (HC). Twenty-one patients diagnosed with MCI (mean age 63.3 ± 7.8 (S.D.) years) underwent PET studies with 11C-PIB, and 18F-fluoro-deoxy-glucose (FDG) to measure cerebral glucose metabolism, as well as assessment of cognitive function and CSF sampling. Reference group data from 27 AD patients and 6 healthy controls, respectively, were used for comparison. The mean cortical PIB retention for the MCI patients was intermediate compared to HC and AD. Seven MCI patients that later at clinical follow-up converted to AD (8.1 ± 6.0 (S.D.) months) showed significant higher PIB retention compared to non-converting MCI patients and HC, respectively (ps < 0.01). The PIB retention in MCI converters was comparable to AD patients (p > 0.01). Correlations were observed in the MCI patients between PIB retention and CSF Aβ1-42, total Tau and episodic memory, respectively.

- To identify the most important agronomic measures and cultivar traits in Swedish organic potato production, multivariate analyses were performed on a set of data from a series of field trials carried out in Sweden during a 7-year period. The effects of soil parameters, cultivar, year and geographical location on potato characteristics were investigated. Soil parameters including fertility level had strong and significant effects on potato characteristics, explaining 53% of total variation. Variables related to the duration of haulm growth were other dominant factors in the variation. While P and K fertilization increased yields, N fertilization had little effect on yield and a negative effect on the time to emergence. The N requirement of potatoes ranges from 2.5 to 5.9 kg ha(-1) per ton of tuber yield and was met in these trials. The results implied the timing of N application is important for yield. It was concluded that the importance of P and K fertilization is underestimated in organic production, and that the most important cultivar trait in achieving acceptable yield is long-lasting foliage, which is a characteristic of cultivars resistant to Phytophthora infestans. Three of the cultivars tested (Lady Balfour, Cicero and Sarpo Mira) had a yield > 3.5 kg m(-2), which is high in Swedish organic production.
