Power and self-perceived health in blind diabetic and nondiabetic individuals.

AIMS: The aims of this study were: (1) to explore perceptions of power in blind individuals and relate presence or absence of power to self-perceived health and (2) to compare self-perceived health in blind individuals with that of the general population. BACKGROUND: The theoretical framework of this study was Barrett's Power theory, which is based on The Rogerian nursing theory. Power is defined as being aware of what one is choosing to do, feeling free to doing it, and do it intentionally. METHODS: Thirty-nine blind subjects at three adjacent ophthalmology centres agreed to participate in the study. Of those 23 had become blind because of late complications of diabetes. Power was explored during semi-structured interviews and self-perceived health was measured with the Swedish health-related quality of life questionnaire. Data on socio-economic, rehabilitative and diabetes-related variables were also collected. FINDINGS: Power was experienced by 19 of the 39 respondents and was more frequently found in nondiabetic subjects than in diabetic subjects. Those experiencing power reported a better emotional and general health compared with individuals lacking power. The perception of having power was not significantly related to any other of the studied variables. When compared with age- and gender-matched controls from the general population, nondiabetic blind subjects scored higher in positive feelings and lower in physical functioning. In contrast diabetic subjects experienced poorer general health, less satisfaction with physical health and more negative feelings, but they reported that they did not experience limitation as a result of these emotions. CONCLUSION: One way of improving health in diabetic blind individuals could be to increase the subject's perception of power.

Health and unhealth in chronic disease.

When health is defined from a holistic view, traditional measures of control in diabetes, such as analysis of blood glucose or HbA1c, are of limited use as indicators of health and unhealth. On the other hand, evaluation of attitudes and certain personality variables might provide guidance both in discovering unhealth and in creating individual self-care programmes for its treatment. In the present study the subjective experience of health and unhealth was studied in a defined population of patients with insulin dependent diabetes mellitus (IDDM). The patients could be divided into three categories: a) those not abandoning important goals because of their diabetes, b) "adapted abandoners" and, c) those abandoning vital aspects of life. On the basis of the findings, the question of how "problem patients" can be identified and treated is discussed.

The patient's experience of diabetes and its treatment: construction of an attitude scale by a semantic differential technique.

An instrument for measuring attitudes towards diabetes and self-care was constructed by a semantic differential technique. The instrument contained nine adjective pairs. Factor analysis classified these into four factors: self-esteem/autonomy, object evaluation, quality of life supporting factor and self-strength/vulnerability. The reliability coefficient of test-retest by 28 nurses/nurse tutors was 0.93. Fifty diabetic patients completed the attitude scale for testing the validity of the instrument. Male patients had a more positive attitude towards diabetes than females. Those who had had diabetes for less than 10 years were more positive than those with a longer duration of the disease. A higher degree of education, well-performed self-monitoring of blood glucose and achievement of good metabolic control were all associated with a more negative attitude towards diabetes. A group of nurses/nurse tutors who also completed the attitude scale had a more negative attitude towards diabetes than the investigated groups of patients.

Tubular proteinuria during treatment with cyclosporin A--a case report.

A patient with relapsing polychondritis developed a progressive destruction of tracheal cartilage despite treatment with immunosuppressive and cytotoxic agents. Cyclosporin A therapy was instituted and has been continued for more than two years, concomitant with a steady improvement and remission of the disease. During the treatment period an increased urinary excretion of beta 2-microglobulin was measured, indicating renal tubular damage. The tubular proteinuria preceded an elevation of serum creatinine and a drop in creatinine-clearance. Thus, beta 2-microglobulin might be a sensitive indicator of nephrotoxicity and of value for the evaluation of the long-term side effects of Cyclosporin A particularly in patients with extrarenal disease.
