Quality of life and coping behaviour in Type 1 diabetes mellitus: relationship with metabolic control

Uncovering factors possibly leading to insufficient metabolic control in Type 1 diabetes, both on the part of the patient or the treating physician, is of considerable relevance. The present long-term study investigated the relevance of patient-related vs education-related factors for the success in achieving acceptable glycaemic control. Adolescents or young adults with Type 1 diabetes mellitus (n= 26, mean age= 22+/-2 yr, diabetes duration= 11+/-5 yr) were followed during 36+/-5 months. All patients were treated by the same diabetologist. At the beginning of the study coping behaviour, quality of life and evaluation of emotional status were assessed. Changes in HbA1c were used as a parameter of glycaemic control. At follow-up there was a significant decrease in HbA1c of 0.4% (p<0.01). However, this was not in statistically significant correlation with age, gender, aspects of quality of life or coping behaviour. Therefore, glycaemic control and/or improvement of glycaemic control in adolescents or young adults with Type 1 diabetes mellitus seems to be primarily related to other factors, eg continuous education provided in a stable setting.

Aortic root replacement does not affect outcome and quality of life

BACKGROUND: Different studies have analyzed the potential impact of the underlying pathologic process and the use of deep hypothermic circulatory arrest on outcome and quality of life after surgery on the thoracic aorta. The aim of this study is to analyze the impact of different surgical procedures on outcome and quality of life. METHODS: Between June 2001 and December 2003, 244 patients underwent surgery for various diseases of the ascending aorta with or without involvement of the aortic valve or root. They were divided according to the operative procedure: 76 patients (31.2%) underwent isolated replacement of the ascending aorta, 42 patients (17.2%) received separate aortic valve replacement and supracoronary replacement of the ascending aorta, 86 patients (35.2%) received a mechanical composite graft, and 40 patients (16.4%) received a biologic composite graft. All in-hospital data were assessed, and a follow-up was performed in all survivors after 26.6 +/- 8.8 months, focusing on outcome and quality of life (SF-36). RESULTS: Overall in-hospital mortality was 6.1%, and late mortality was 5.7%, with no significant difference between groups. Independent of the surgical technique and the extent of surgery, there was no difference in quality of life between the surgical collective and an age-matched and sex-matched standard population. CONCLUSIONS: Operations of the ascending aorta and aortic valve are very safe, with low in-hospital mortality and favorable midterm outcome regarding late mortality and morbidity. Quality of life after operations of the ascending aorta and aortic valve is equal to a standard population and is not affected by the surgical procedure. Liberal use of aortic root replacement is therefore justified to radically treat the diseased aortic segment.

Intermediate results of health related quality of life after vertical banded gastroplasty

OBJECTIVES: The purpose of this study is to evaluate (a) health-related quality of life (HRQL) after vertical banded gastroplasty (VBG) (Mason) and (b) predictors of HRQL. SUBJECTS: Eighty-two consecutive patients were assessed preoperatively and then after 6, 12 and 24 months. Patients filled out questionnaires for subjective appraisal of HRQL (physical well-being, mood, physical performance, perceived health, social support and coping/adjustment). RESULTS: The greatest improvement in weight and HRQL was seen within 6 months of surgery. Twenty-four months after VBG weight reduction (P<0.05), perceived health (P<0.05), physical well-being (P<0.05), physical performance (P<0.05), mood (P<0.05), coping/adjustment (P<0.05) continued to be better than before surgery. Preoperative binge eating was the most important predictor of HRQL. CONCLUSION: Two years after VBG weight loss and a significant improvement of HRQL can be found. HRQL and weight loss are not associated in terms of outcome, indicating that weight loss alone may not be enough to improve HRQL.

Content comparison of health-related quality of life instruments for COPD

BACKGROUND: Due to the increasing importance of quality of life assessments in chronic obstructive pulmonary disease (COPD) patients, and the increased use of the International Classification of Functioning, Disability and Health (ICF) for comparative purposes it is essential to understand the relationship between health-related quality of life (HRQL) instruments and the ICF. OBJECTIVE: The objective of this study was to compare the content of recommended COPD-specific HRQL instruments using the ICF as reference. COPD-specific instruments mentioned in widely accepted guidelines were linked to the ICF using standardized linking rules. The degree of agreement between various health professionals was assessed by calculating the kappa statistic. RESULTS: Eleven instruments were included. They varied strongly in the number of concepts contained and the number of ICF categories used to map these concepts. A total of 548 concepts were identified and linked to 60 different ICF categories. Only the single category 'dyspnea' was covered by all instruments, whilst 21 categories were unique to specific instruments. The relationships of the measures with the ICF were identified. CONCLUSIONS: This study may aid researchers and clinicians to choose the most appropriate instrument for a specific purpose as well as help compare studies that have used different instruments for HRQL assessment.

Effects of a comprehensive rehabilitation program on quality of life in patients with chronic heart failure

This evaluation was performed to assess the effects of a new, comprehensive outpatient rehabilitation program on generic and disease-specific quality of life related to exercise tolerance in stable chronic heart failure patients. Fifty-one patients (aged 59+/-11 years; 84% men) were treated for 12 weeks. Patients underwent optimized drug treatment, exercise training, and counseling and education. At baseline and at the end of the program, functional status, exercise capacity, and quality of life were assessed using the Medical Outcomes Study 36-item Short-Form Health Survey and the Minnesota Living with Heart Failure Questionnaire. Left ventricular ejection fraction and New York Heart Association functional class, as well as measures of physical fitness and walking distance covered in 6 minutes, improved significantly (by 11%-20% and by 58% on average, respectively). Physical functioning (effect size, 0.38; p<0.0001), role functioning (effect size, 0.17; p<0.05), and mental component score (effect size, 0.47; p<0.0001) on the questionnaire improved significantly. Disease-specific quality of life improved in sum score (effect size, 0.24; p<0.0001) and physical component score (effect size, 0.35; p<0.0001). The latter was inversely correlated to improvement in peak power output (r= -0.31; p<0.05). In patients with stable chronic heart failure, significant improvements in both generic and disease-specific quality of life related to improved exercise tolerance can be achieved within 12 weeks of comprehensive rehabilitation.

[Survival, clinical data and quality of life 10 years after heart transplantation: a prospective study]

AIM: To study prospectively patients after heart transplantation with respect to quality of life, mortality, morbidity, and clinical parameters before and up to 10 years after the operation. METHODS: Sixty patients (47.9 +/- 10.9 years, 57 men, 3 women) were transplanted at the University of Vienna Hospital, Department for Heart and Thorax Surgery and were included in this study. They were assessed when set on the waiting list, then exactly one, 5 and 10 years after the transplantation. The variables evaluated included physical and emotional complaints, well-being, mortality and morbidity. In the sample of patients who survived 10 years (n = 23), morbidity (infections, malignancies, graft arteriosclerosis, and rejection episodes) as well as quality of life were evaluated. RESULTS: Actuarial survival rates were 83.3, 66.7, 48.3% at 1, 5, and 10 years after transplantation, respectively. During the first year, infections were the most important reasons for premature death. As a cause of mortality, malignancies were found between years 1 and 5, and graft arteriosclerosis between years 5 and 10. Physical complaints diminished significantly after the operation, but grew significantly during the period from 5 to 10 years (p < 0.001). However, trembling (p < 0.05) and paraesthesies (p < 0.01) diminished continuously. Emotional complaints such as depression and dysphoria (both p < 0.05) increased until the tenth year after their nadir at year 1. In long-time survivors, 3 malignancies (lung, skin, thyroidea) were diagnosed 6 to 9 years postoperatively. Three patients (13%) had signs of graft arteriosclerosis at year 10; 9 (40%) patients suffered from rejection episodes during the course of 10 years. There were no serious rejection episodes deserving immediate therapy. Quality of life at 10 years is good in these patients. CONCLUSIONS: Heart transplantation is a successful therapy for patients with terminal heart disease. Long-term survivors feel well after 10 years and report a good quality of life.

Long-term effects of supervised exercise training on walking capacity and quality of life in patients with intermittent claudication

Supervised exercise training has been shown to improve walking capacity in several studies of patients with intermittent claudication. However, data on long-term outcome are quite limited. The aim of this prospective study was to evaluate long-term effects of supervised exercise training on walking capacity and quality of life in patients with intermittent claudication. Patients and methods: Sixty-seven consecutive patients with intermittent claudication who completed a supervised 12-week exercise training program were asked for follow up evaluation 39 +/- 20 months after program completion. Pain-free walking distance (PWD) and maximum walking distances (MWD) were assessed by treadmill test and several questionnaires. Results: Forty (60%) patients agreed to participate, 22 (33%) refused participation, and 5 (7%) died during follow-up. PWD and MWD significantly improved at completion of 12-weeks supervised exercise training as compared to baseline (PWD 114 +/- 100 vs. 235 +/- 248, p = 0.002; MWD 297 +/- 273 vs. 474 +/- 359, p = 0.001). Improvement of PWD and MWD could be maintained at follow up (197 +/- 254, p = 0.014; 390 +/- 324, p = 0.035, respectively) with non-smokers showing significantly better sustained PWD and MWD improvement as compared to baseline. Overall, walking capacity correlated with functional status of quality of life. Conclusions: Major findings of this investigation were that improvement in walking capacity is sustained after completion of supervised exercise training program with best results in patients who quitted or never smoked. Improved walking capacity is associated with increased functional status of quality of life.

Psychometric properties of the MacNew heart disease health-related quality of life instrument in patients with heart failure

RATIONALE, AIMS AND OBJECTIVES: Heart failure (HF) is a severe chronic disease and impairs health-related quality of life (HRQL). While validated specific HRQL instruments are required for evaluation of treatment and rehabilitation in patients with HF, a single validated measure to document changes in HRQL for patients with different heart disease diagnoses would be invaluable. The purpose of this analysis was the psychometric analysis of the German MacNew Heart Disease Questionnaire (MacNew) in HF patients, which has previously been shown to be reliable and valid in patients with myocardial infarction, angina pectoris and arrhythmia. METHODS: We recruited 89 patients (61.7+/-11.5 years; 84.3% male) in two Austrian and one Swiss cardiology department with documented HF (effect sizes 28.9+/-10.1%). The self-administered MacNew, the Short Form-36 (SF-36) and the Hospital Anxiety and Depression Scale were completed. Internal consistency reliability (Cronbach's alpha), discriminative and evaluative validity were assessed. RESULTS: Cronbach's alpha exceeded 0.80. Each MacNew scale differentiated between patients with and without anxiety (3.9+/-1.0 vs. 5.3+/-0.8, all P<0.001), with and without depression (4.2+/-1.2 vs. 5.2+/-0.9 all P<0.03) and by the SF-36 health transition item (deteriorate=4.39, no change=4.95, improve=5.45, all P<0.02). Evaluative validity was demonstrated with effect sizes >0.70 for a subsample attending a 12-week outpatient rehabilitation programme. CONCLUSIONS: The German language version of the MacNew demonstrates consistently acceptable psychometric properties of reliability, validity and responsiveness in patients with documented HF. Together with previous documentation of reliability, validity and responsive, these findings strengthen the argument for the MacNew as a potential 'core' HRQL measure, at least in the German language.

Quality of life and quality-adjusted survival (Q-TWiST) in patients receiving dose-intensive or standard dose chemotherapy for high-risk primary breast cancer

Quality of life (QL) is an important consideration when comparing adjuvant therapies for early breast cancer, especially if they differ substantially in toxicity. We evaluated QL and Q-TWiST among patients randomised to adjuvant dose-intensive epirubicin and cyclophosphamide administered with filgrastim and progenitor cell support (DI-EC) or standard-dose anthracycline-based chemotherapy (SD-CT). We estimated the duration of chemotherapy toxicity (TOX), time without disease symptoms and toxicity (TWiST), and time following relapse (REL). Patients scored QL indicators. Mean durations for the three transition times were weighted with patient reported utilities to obtain mean Q-TWiST. Patients receiving DI-EC reported worse QL during TOX, especially treatment burden (month 3: P<0.01), but a faster recovery 3 months following chemotherapy than patients receiving SD-CT, for example, less coping effort (P<0.01). Average Q-TWiST was 1.8 months longer for patients receiving DI-EC (95% CI, -2.5 to 6.1). Q-TWiST favoured DI-EC for most values of utilities attached to TOX and REL. Despite greater initial toxicity, quality-adjusted survival was similar or better with dose-intensive treatment as compared to standard treatment. Thus, QL considerations should not be prohibitive if future intensive therapies show superior efficacy.

Cognitive functioning, behavior, and quality of life after stroke in childhood

Rationale: To provide a better understanding of cognitive functioning, motor outcome, behavior and quality of life after childhood stroke and to study the relationship between variables expected to influence rehabilitation and outcome (age at stroke, time elapsed since stroke, lateralization, location and size of lesion). Methods: Children who suffered from stroke between birth and their eighteenth year of life underwent an assessment consisting of cognitive tests (WISC-III, WAIS-R, K-ABC, TAP, Rey-Figure, German Version of the CVLT) and questionnaires (Conner's Scales, KIDSCREEN). Results: Twenty-one patients after stroke in childhood (15 males, mean 11;11 years, SD 4;3, range 6;10-21;2) participated in the study. Mean Intelligence Quotients (IQ) were situated within the normal range (mean Full Scale IQ 96.5, range IQ 79-129). However, significantly more patients showed deficits in various cognitive domains than expected from a healthy population (Performance IQ p = .000; Digit Span p = .000, Arithmetic's p = .007, Divided Attention p = .028, Alertness p = .002). Verbal IQ was significantly better than Performance IQ in 13 of 17 patients, independent of the hemispheric side of lesion. Symptoms of ADHD occurred more often in the patients' sample than in a healthy population (learning difficulties/inattention p = .000; impulsivity/hyperactivity p = .006; psychosomatics p = .006). Certain aspects of quality of life were reduced (autonomy p = .003; parents' relation p = .003; social acceptance p = .037). Three patients had a right-sided hemiparesis, mean values of motor functions of the other patients were slightly impaired (sequential finger movements p = .000, hand alternation p = .001, foot tapping p = .043). In patients without hemiparesis, there was no relation between the lateralization of lesion and motor outcome. Lesion that occurred in the midst of childhood (5-10 years) led to better cognitive outcome than lesion in the very early (0-5 years) or late childhood (10-18 years). Other variables such as presence of seizure, elapsed time since stroke and size of lesion had a small to no impact on prognosis. Conclusion: Moderate cognitive and motor deficits, behavioral problems, and impairment in some aspects of quality of life frequently remain after stroke in childhood. Visuospatial functions are more often reduced than verbal functions, independent of the hemispheric side of lesion. This indicates a functional superiority of verbal skills compared to visuospatial skills in the process of recovery after brain injury. Compared to the cognitive outcome following stroke in adults, cognitive sequelae after childhood stroke do indicate neither the lateralization nor the location of the lesion focus. Age at stroke seems to be the only determining factor influencing cognitive outcome.

Mental health and quality of life after genetic testing for Huntington disease: a long-term effect study in Germany

Predictive genetic testing for Huntington disease (HD) might cause severe short-term psychological reactions in patients with poor mental health. Very few studies exist on the long-term effects of genetic HD testing. The aim of this study was to assess mental health and quality of life in persons who were tested for HD mutation, to compare mental health depending on the result of the genetic test (non-carriers, gene carriers, and patients with HD) and to identify predictors of mental health and quality of life via linear regression. The data were collected by self-report questionnaires. In total, 121 individuals participated in this study: 52 were non-carriers, 54 were gene carriers, and 15 were gene carriers suffering from HD. Non-carriers and gene carriers showed better mental health and quality of life than HD-patients but did not differ from each other. In non-carriers four variables predicted increased depression and low mental quality of life: low perceived social support, no intimate relationship, female sex and younger age. For gene carriers three predictors were found: low perceived social support, the expectation of an unfavorable genetic test result before the testing procedure and being childless. To prevent detrimental effects of HD testing on mental health and mental quality of life, specific attention should be paid to persons with limited social networks during genetic counseling. Assessment of expectations related to the test result and mental health prior to a genetic testing procedure may help to identify gene carriers at risk of poor coping after an unfavorable test result.

Quality of life 15 years after sex reassignment surgery for transsexualism

OBJECTIVE: To evaluate quality of life and patients' satisfaction in transsexual patients (TS) after sex reassignment operation compared with healthy controls. DESIGN: A case-control study. SETTING: A tertiary referral center. PATIENT(S): Patients after sex reassignment operation were compared with a similar group of healthy controls in respect to quality of life and general satisfaction. INTERVENTION(S): For quality of life we used the King's Health Questionnaire, which was distributed to the patients and to the control group. Visual analogue scale was used for the determination of satisfaction. MAIN OUTCOME MEASURE(S): Main outcome measures were quality of life and satisfaction. RESULT(S): Fifty-five transsexuals participated in this study. Fifty-two were male-to-female and 3 female-to-male. Quality of life as determined by the King's Health Questionnaire was significantly lower in general health, personal, physical and role limitations. Patients' satisfaction was significantly lower compared with controls. Emotions, sleep, and incontinence impact as well as symptom severity is similar to controls. Overall satisfaction was statistically significant lower in TS compared with controls. CONCLUSION(S): Fifteen years after sex reassignment operation quality of life is lower in the domains general health, role limitation, physical limitation, and personal limitation.
