- In the Piteå River Valley all persons with memory impairment that interferes with normal life are referred to one hospital department for clinical workup and diagnosis. 619 patients were assessed in the department during the years 1990–1995. Of these, 36.9% had Alzheimer’s disease (AD), 30.4% had vascular dementia (VaD), 3.0% had a mixed AD/VaD, 3.2% had frontotemporal dementia and 5.3% had other forms of dementia. Another 7% had memory impairment but no dementia. The overall mean annual incidence rate of clinically relevant dementia was 295/100,000 persons at risk and the mean prevalence rate was 755/100,000 persons. For persons 65 years and older the incidence and prevalence rates were 840 and 2,150/100,000 persons, respectively. This means that annually, approximately 300 persons/100,000 population over the age of 40 need medical attention or social services.

- Hellsten, Ylva, Fred S. Apple, and Bertil Sjödin.Effect of sprint cycle training on activities of antioxidant enzymes in human skeletal muscle. J. Appl. Physiol. 81(4): 1484–1487, 1996.—The effect of intermittent sprint cycle training on the level of muscle antioxidant enzyme protection was investigated. Resting muscle biopsies, obtained before and after 6 wk of training and 3, 24, and 72 h after the final session of an additional 1 wk of more frequent training, were analyzed for activities of the antioxidant enzymes glutathione peroxidase (GPX), glutathione reductase (GR), and superoxide dismutase (SOD). Activities of several muscle metabolic enzymes were determined to assess the effectiveness of the training. After the first 6-wk training period, no change in GPX, GR, or SOD was observed, but after the 7th week of training there was an increase in GPX from 120 ± 12 (SE) to 164 ± 24 μmol ⋅ min−1 ⋅ g dry wt−1( P < 0.05) and in GR from 10.8 ± 0.8 to 16.8 ± 2.4 μmol ⋅ min−1 ⋅ g dry wt−1( P < 0.05). There was no significant change in SOD. Sprint cycle training induced a significant ( P < 0.05) elevation in the activity of phosphofructokinase and creatine kinase, implying an enhanced anaerobic capacity in the trained muscle. The present study demonstrates that intermittent sprint cycle training that induces an enhanced capacity for anaerobic energy generation also improves the level of antioxidant protection in the muscle.

- The effects of eccentric exercise on changes in numbers of circulating leukocytes, cell activation, cell adhesion, and cellular memory function were investigated in 12 men, aged 22–35 yr. The immunologic effects of postexercise epidermal treatment with monochromatic, infrared light were also evaluated. Blood was drawn before and 6, 24, and 48 h after exercise for phenotyping and analysis of creatine kinase activity. There was an increase in leukocyte, monocyte, and neutrophil number, no change in the number of basophils, eosinophils, B cells, and T cells, and a decrease in natural killer cell number postexercise. Some markers of lymphocyte and monocyte activation remained unchanged or decreased, whereas the expression of adhesion molecules 62L and 11b increased on monocytes. It is concluded that eccentric exercise induced decreased activation, and increased cell adhesion capacity, of monocytes. Altered trafficking of cells between lymphoid tissue and blood, selective apoptosis, or attachment/detachment from the endothelial wall can explain the observed phenotypic changes. Treatment with monochromatic, infrared light did not significantly affect any of the investigated variables. Correlations between immunologic and physiological parameters indicate a role of the immune system in adaptation to physical exercise.
