Impact of cognitive reserve on dance intervention-induced changes in brain plasticity.

Dance is a complex sensorimotor activity with positive effects on physical fitness, cognition, and brain plasticity in the aging population. We explored whether individual levels of cognitive reserve (CR) proxied by education moderate dance intervention (DI)-induced plasticity assessed by resting-state functional connectivity (rs-FC) changes of the sensorimotor network (SMN), and between the dorsal attention network (DAN) and anterior default mode network (aDMN). Our cohort consisted of 99 subjects, randomly assigned to either a DI group who underwent a 6-month intervention (n = 49, M = 69.

[Pulsed doses of calcitriol in the treatment of secondary hyperparathyroidism in patients on hemodialysis].

Administration of pulse doses of calcitriol is a better way of conservative treatment of secondary hyperparathyroidism (2HPT), making use of the direct suppression of parathormone (PTH) secretion. In a group of 29 haemodialyzed patients the authors evaluated during a six-month follow-up the effect of intravenous Calcijex in 12 and of oral Rocaltrol in 8 subjects. In responders of the calcijex group the PTH level declined by 67.

[Successful completion of pregnancy in a dialyzed patient].

The authors describe the first case of a successful pregnancy in the Czech Republic in a patient treated by continuous ambulatory peritoneal dialysis. The 22-year-old patient became pregnant ten months after the onset of treatment by peritoneal dialysis. During pregnancy deterioration of arterial hypertension occurred, deterioration of anaemia and from the 29th week onwards cholestasis gravidarum developed.

[The locomotor system in irreversible renal failure treated with regular dialysis].

Changes of the locomotor apparatus in prolonged uraemia with regular dialyzation treatment determine the quality of life with all its consequences for the patient. The greatest impact on osteodystrophic disease (the most typical finding on the skeleton) is exerted by the length of dialyzation treatment. Of 216 patients having regular dialyzation treatment in 1979 to 1992 the authors observed osteodystrophic disease in 25, i.

[Oxalosis in patients on regular dialysis therapy].

The authors draw attention to the case of a 46-year-old man who developed after three years of regular dialyzation treatment three times a week the first manifestations of acquired generalized oxalosis. The oxalosis was most marked on the skin, skeleton, heart, and kidneys. Oxalosis was confirmed after eight years of dialysis after death by post-mortem and histological examination and microscopic detection of oxalate crystals.
