Medical laboratory technologists' perception of professional self. A study of Swedish MLTs employed in clinical chemistry.

The subjective perception of professional self was studied for a sample of Medical Laboratory Technologists (MLTs) employed in Clinical Chemistry in Sweden. The sample (N = 488) consisted of a randomized tenth of members of their trade union. A mailed questionnaire with 21 items concerning self-description compared with peers in a seven-point Likert type scale was completed by 332 (68%). There was no significant overall difference concerning the four principal types of workplace: Clinical Chemistry, Blood Serology, Primary Care and Clinical Chemistry/Blood Serology. The main difference was found between those in managerial posts (N = 72) and the other MLTs (N = 260). Factor analysis showed three principal components, labelled Professionalism, Work Ethic, and Empathy, but also a different composition of variables of the components for the manager group compared with the non-manager group.

Testing daily functions post-stroke with standardized practical equipment.

Two hundred and seven stroke patients were tested with Standardized Practical Equipment (SPE) three months after a stroke. One year after the stroke 183 survivors from this stroke population were tested with the equipment. The SPE test consists of 12 common daily activities, which the patient was asked to perform. The construct validity of SPE was estimated by factor analysis from the results of one-year follow-up. Three factors explained 82% of the variance of the 12 variables of SPE. Factor 1 mainly concerned cognitive factors and co-ordination, Factor 2 construction and hand function and Factor 3 variables that were dependent on mobility and balance. No significant difference was noted between the performance with SPE three months and one year after the stroke among the one-year survivors. There were some differences between men and women; for example the men were more successful in tasks with technical components. The women had more difficulty with some of the tasks involving mobility, such as climbing stairs without support. The Standardized Practical Equipment gave good additive information about the ability of a stroke patient to manage at home and could be used in any set-up.

Changes of reactive hyperaemia after clinical bed rest for seven days.

As an indication of peripheral circulatory function reactive hyperaemia was studied in the forearm and calf muscle in 14 healthy young men before and after clinical bed rest for one week. Blood flow was measured after different arterial occlusion times with venous occlusion plethysmography. After bed rest peak flow values in the calf after arterial occlusion for 3 or 5 minutes decreased moderately (by about 20-23%) and significantly. Peak flow in the forearm decreased as well although not significantly.
