Quality of life in patients before and after haematopoietic stem cell transplantation measured with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire QLQ-C30.

The EORTC Quality of Life Core Questionnaire QLQ-C30 is widely used, but no reference values are available for patients receiving HSCT. We retrieved data for 38 samples from 33 papers in English and German that provided evaluable information on QLQ-C30 scores (mean, s.d.) covering about 2800 patients. Results are presented as a table that provides reference data that allow QLQ-C30 scores at different points during the disease trajectory to be put in context. With respect to their central tendency and their variance, scores vary over time. Quality of life is lowest during inpatient time. About 1 year after HSCT, the pre-transplant level is reached. Physical functioning is the scale reaching the highest level of all scales. Fatigue, dyspnoea and insomnia are symptoms that remain at an elevated level and should thus be considered as persisting problems after HSCT. For the interpretation of differences between scores, a very conservative recommendation would be to set the s.d. at 30 points. Doing so, one could be quite sure of having found a clinically significant change if the difference of two scores exceeds 15 points. Differences below 5 points should be interpreted with caution.

[The emotional sensitivity of elderly people--validation of the Profile of Mood States for people over 60 years]. / Die emotionale Befindlichkeit älterer Menschen -- Normierung des Profile of Mood States für über 60-Jährige.

The German short version of the "Profile of Mood States (POMS)" with 35 items (seven-point response scale; rating related to the past 24 hours) was psychometrically tested in a sample of elderly people of 60 years of age and older (n=690; 57% female). The internal structure of the POMS with four factors (dejection, fatigue, displeasure, vigour) could largely be replicated, even though the first three factors are intercorrelated. Reliability of the scales appears to be very good. The convergent validity of the POMS scales could be proved by correlations with the Beck Depression Inventory and the SF-36. Specific norms are presented for four age groups, men and women and elderly living in Eastern and Western Germany. So it seems appropriate to use the German short version of the POMS as a valid and economic instrument for gerontological studies.

Psychological distress of patients undergoing intensified conditioning with radioimmunotherapy prior to allogeneic stem cell transplantation.

This is a pilot study comparing the emotional distress of patients receiving an intensified conditioning regimen (radioimmunotherapy=RIT) with patients receiving conventional conditioning for allogeneic stem cell transplantation. In total, 53 patients (18 received RIT) were given two questionnaires designed to measure emotional distress (HADS, POMS) before starting conditioning (t1) and at discharge (t2). During the in-patient period, patients answered questions daily relating to physical distress, psychological distress, and how they were "coping with the situation". At t2, the transplant team assessed the manner in which the patients were coping. The data displayed no relevant differences with regard to emotional distress between the two groups, both at t1 and t2. For both groups, anxiety and vigor decreased and fatigue increased between t1 and t2. On average, perceived distress was higher for those patients being treated with RIT during the in-patient time, but the differences between both groups were significant only regarding physical distress during the recovery period. No difference was found for the transplant team's assessment. We hypothesize that an intensified conditioning regimen with RIT per se has only a small distressing effect on the patients' psyche during their stay at the hospital. Differences between both groups probably result from independent factors such as, for example, the patients' pre-existing health conditions.

[Religiosity and spirituality in the elderly]. / Religiosität und Spiritualität im Alter.

The present paper presents results regarding religious attitudes and behaviors as well as the perceived social support by religious communities in n = 593 elderly over 60 years (31.2% female, mean age 69.5 years) from the German general population. The results are based on the German 15-item version SBI-15R-D of the "Systems of Belief Inventory" (Holland et al., 1998). Furthermore, religiosity was analyzed as a potential protective factor regarding body complaints in the elderly. Higher scores on religiosity could be found in women compared to men and in elderly from Western Germany compared to those from Eastern Germany. There were no significant correlations between religiosity and body complaints. It is discussed whether the self-ratings of religiosity reflect conventional ideas of a religious orientated person rather than a genuine spiritual attitude.

[Effects of high iodine doses in parenteral roentgen contrast media administration on parameters of the pro-/antioxidant balance]. / Einfluss hoher Joddosen in Form eines parenteral verabreichten Röntgenkontrastmittels auf Parameter des pro-/antioxidativen Gleichgewichts.

The aim of this study was to investigate effects of high iodine doses given parenterally as contrast medium on parameters of lipid status and thyroid hormone status as well as on parameters of the pro/antioxidative balance of spa patients. 29 patients with a comparable indication who had to undergo an angiography were chosen. The blood parameters of these patients were determined before and after the angiographic treatment. No provable changes of the thyroid parameters f-T3, f-T4 and TSH were found after the angiography. In case of enzyme activities, the protective enzymes SOD and GSHPX showed no changes, while the concentrations of peroxides and MDA were increased significantly. Corresponding to this, the total antioxidative status and the vitamin E level decreased significantly. Altogether these results stand for a moderate deterioration of the antioxidative protective potential by the highly iodine containing contrast medium.

Does motion analysis in postexercise gated sestamibi SPECT reflect rest left ventricular motion even in severe coronary artery disease?

PURPOSE: Evidence has suggested that postexercise gated Tc-99m sestamibi SPECT (GSPECT) provides combined information about resting wall motion and exercise perfusion. No data have been published about possible differences in wall motion analysis between postexercise and resting GSPECT. METHODS: Fifty patients underwent postexercise (symptom-limited bicycle stress) and rest GSPECT and cardiac catheterization with contrast ventriculography. In 35 patients, additional rest planar Tc-99m RBC radionuclide ventriculography (RNV) was performed. Four observers independently performed left ventricular ejection fraction (LVEF) calculations and visual analysis of regional wall motion (graded in four stages) for all studies. RESULTS: The LVEF calculations in GSPECT revealed a statistically significant difference between postexercise (45.8 +/- 15.7%) and rest (48.0 +/- 16.1%; P < 0.05) determination. Postrest GSPECT LVEF showed a better correlation with LVEF determination performed with contrast ventriculography and RNV than did postexercise GSPECT LVEF. The reduced postexercise wall motion could be shown in segments with exercise-induced ischemia and in those with normal regional perfusion but not in segments with irreversibly abnormal perfusion. CONCLUSIONS: Postexercise GSPECT provides reliable information regarding global wall motion even in severe coronary artery disease, but regional wall motion is underestimated compared with rest GSPECT, because of an imprecise surface detection algorithm in ischemic wall segments and possibly postexercise stunning in severe coronary artery disease.

ROC analysis of three perfusion display options for ECG-gated perfusion SPECT in severe CAD.

AIM: The simultaneous computation and display of wall motion and perfusion patterns in a single 3D ventricular model would considerably ease the assessment of ECG-gated Tc-99m-sestamibi SPECT, yet the effect on the accuracy of allocating regional perfusion has so far not been validated. METHODS: 3D perfusion mapping (3D Perfusion/Motion Map Software) was compared to the visual assessment of ungated tomographic slices and polar perfusion mapping (Cedars-Sinai PTQ) by correlation analysis and receiver operating characteristics (ROC) analysis at different cut-off levels for coronary stenoses in 50 patients (11 single-, 22 two-, 16 three-vessel disease). Ungated SPECT data were obtained by adding the intervals prior to reconstruction and displaying conventional tomographic slices. All display options were visually assessed in 8 ventricular segments according to a 4-point scoring system and compared to the graded results of coronary angiography. RESULTS: All three display options showed a comparable diagnostic performance for the detection of severe stenoses. The diagnostic gain for the detection of stenoses above 59% was highest for ungated tomographic slices, followed by ungated polar mapping and 3D mapping. Regional assessment revealed a limited performance of 3D mapping in the proximal anterior and distal lateral wall. Polar mapping showed a balanced regional performance. CONCLUSION: 3D Perfusion mapping provides comparable information to conventional display options with the highest diagnostic strength in severe stenoses. Further improvement of the algorithm is needed in the definition of the valve plane.

Four year follow-up of the Duromedics Edwards bileaflet valve prostheses.

The Duromedics Edwards (DE) bileaflet valve prosthesis was withdrawn from the market after 12 leaflet escapes had been reported in 20,000 implants. Effort is necessary to identify the failure mode to improve valve design or production, but the rate of other valve related complications will tell if it is worthwhile reintroducing this prosthesis. Five-hundred and sixty-four DE valves have been implanted in 508 patients between September 1983 and May 1988. Two-hundred and sixty-eight had aortic valve replacement (AVR), 183 mitral valve replacement (MVR) and 56 double valve replacement (DVR); the perioperative mortality was 6.9%. Follow-up has been 98.7% complete for a total of 1064 patient years and a mean follow-up of 26 months (range 3 to 54 months). Late mortality was 3.7%/yr and actuarial survival was 85 +/- 3% without and 78 +/- 3% including operative mortality after 54 months. Event free actuarial rates (linearized rates in parenthesis) were 93 +/- 2% (1.5%/yr) for thromboembolism, 91.7 +/- 1.9% (2.3%/yr) for anticoagulant related hemorrhage, 89 +/- 4.8% (2.3%/yr) for valve failure, 93 +/- 2% (1.8%/yr) for valve related mortality, 72 +/- 4.8% (6.3%/yr) for all valve related morbidity and mortality and 83 +/- 4.4% (3%/yr) for treatment failure. Two leaflet escapes occurred in the study group (0.18%/yr), both patients survived reoperation. The concept of reducing thrombus formation by a specially designed irrigating hinge mechanism was proven by a low rate of thromboembolism in our clinical follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

[Immunoscintigraphy with a technetium 99m-labeled monoclonal antibody in patients with melanoma]. / Immunszintigraphie mit einem Technetium-99-m-markierten monoklonalen Antikörper bei Patienten mit Melanom.

In 24 patients with malignant melanoma the clinical feasibility of immunoscintigraphy (ISC) with a Tc99m-labeled F(ab)2 fragment of an anti-melanoma monoclonal antibody was evaluated. This antibody (225.28S) recognizes a human high molecular weight melanoma associated antigen with restricted tissue distribution, which is expressed on melanoma cells in about 90%. The results of ISC were related with the clinical stage of the patients and the level of invasion of the primary tumor (Clark level). Results of ISC indicate the possibility that patients with the highest Clark level have a higher incidence of false negative scintigrams than those with lower levels of invasion of the primary tumor. In 3 out of 5 patients with Clark level 5 false negative scintigrams were found, whereas in 14 patients with lower Clark levels ISC was true positive, however, the number of metastases was underestimated. 14 of 18 patients with clinical stage II-IIIb had positive scans visualizing 27 of 59 metastases. Thus overall sensitivity was 77% and regional sensitivity 46%. Scintigraphically lesions in lymph-nodes, liver and skin were frequently detected, whereas ISC was less sensitive for lung, bone and brain metastases. No false positive findings were observed by ISC (specificity 100%). Relating the sensitivity and specificity of ISC to the prevalance of disease post-test likelihoods for a normal and an abnormal test result were calculated. Post-test likelihood for the disease with an abnormal scintigraphic finding is 100%. However, with a disease prevalance of 75%, according to our patients, the predicitive value of a normal test result is 60%, thus the post-test likelihood for the disease remains rather high (40%).(ABSTRACT TRUNCATED AT 250 WORDS)
