[Validation of the quality of life questionnaire in arterial hypertension (HQALY) for its use in Spain. Relationship between clinical variables and quality of life. Investigator Group of the HQALY study].

OBJECTIVE: To evaluate the measurement properties of the Hypertension Quality of Life (HQALY) questionnaire, under normal clinical practice conditions, and the relationship between quality of life and clinical variables in patients with hypertension. DESIGN: Observational, prospective and multi-centred study. SETTING: 92 primary care centres in Spain. PARTICIPANTS: 269 patients, of both sexes and over 17, with hypertension, stratified by age (18-44, 45-64 and over 64), sex and organic complaint. 106 individuals over 17 with normal tension were chosen at random. INTERVENTIONS: Intensification of treatment in hypertense patients. MEASUREMENTS: Administration of the HQALY and the EuroQol-5D at every attendance (patients, basal and at a month; controls, basal). In addition, at the basal attendance social-demographic and clinical features were recorded, and at the attendance at a month the clinical features and changes in health status. MAIN RESULTS: Mean time of administration was 28 (23) minutes. VALIDITY: factor analysis showed two dimensions, state of mind and somatic manifestations, which correlated most closely with the dimensions of anxiety/depression (0.64) and pain/discomfort (0.55) on the EQ-5D, respectively. HQALY scores were higher (worse quality of life) in patients than in controls without hypertension (p < 0.01). Reliability: intraclass correlation coefficient was 0.88 in state of mind and 0.76 in somatic manifestations. Cronbach's alpha was 0.96 and 0.89, respectively. Sensitivity: the "size of the effect" at a month from starting treatment for hypertension was 0.40. Hypertension for over 10 years, more organs affected, gravity and morbid obesity were associated with worse quality of life, especially in the state-of-mind dimension. Cardiac frequency correlated closer with state of mind than somatic manifestations. CONCLUSIONS: The HQALY is the first specific hypertension questionnaire developed in Spain which has been shown valid, reliable and sensitive to changes. However, the number of items on it must be reduced for routine use in clinical practice.

Life expectancy, comorbidity and quality of life: the treatment equation in the older cancer patients.

With ageing, function preservation and maintenance of quality of life represent a major goal in an increasing proportion of patients. Life expectancy is a function of age, comorbidity, disability and cancer type and stage. Decision-making involves a delicate balance among all these factors, evaluation of treatment related complications of the overall effects of cancer and cancer treatment on the patients' quality of life. Despite several instruments for the assessment of quality of life being validated, none have been calibrated to the special requirements of the older patients. The structured interview administered by a trained clinician represents a standard approach for geriatric research and even for clinical practice because of the frailty of the older population. The combination of this approach with the self-administered questionnaire appears the most effective way to minimise missing data in collecting information for patients unable to complete the form.

A cardiovascular life history. A life course analysis of the original Framingham Heart Study cohort.

AIMS The objective of this paper is to measure the potential burden of cardiovascular disease within the original Framingham Heart Study cohort by transforming its well-described epidemiological measures into time-based health policy measures, such as life years lost to or lived with the disease. METHODS AND RESULTS We constructed multi-state life tables of the Framingham Heart Study cohort to calculate dwelling times with a history of cardiovascular disease. Age-specific probabilities determined transitions from healthy through disease to death. For this synthetic cohort, from age 50 men (women) live on average 26 (32) years; 20 (26) free of cardiovascular disease. Allowing occupancy of more than one disease state, 50-year-old males (females) live 2 X 9 (1 X 2) years with a history of myocardial infarction, 0 X 93 (1 X 2) with a history of stroke, and 0 X 67 (0 X 93) with congestive heart failure. Having ever suffered acute myocardial infarction, stroke or congestive heart failure, life expectancy is reduced by 9 (13), 12 (15) or 16 (16) years, respectively in 60-year-old men (women). CONCLUSIONS Transforming occurrence probabilities into time-based health measures, the prevalence of cardiovascular disease is remarkable: from age 50, 20% of remaining life expectancy is lived with the disease. Such measures are integral to appropriate health planning and assessment of the potential population health value of various treatment and prevention strategies.

Embryonic life and human life.

A new human life comes into being not when there is mere cellular life in a human embryo, but when the newly developing body organs and systems begin to function as a whole, the author argues. This is symmetrical with the dealth of an existing human life, which occurs when its organs and systems have permanently ceased to function as a whole. Thus a new human life cannot begin until the development of a functioning brain which has begun to co-ordinate and organise the activities of the body as a whole.

Quantifying the future impact of disease on society: life table-based measures of potential life lost.

OBJECTIVES: Quantifying health status in human populations by means of an index such as "years of potential life lost" has recently received attention. However, such an index, being cross-sectional in nature, only measures the current burden to society resulting from a specific cause of death. METHODS: The author proposes new indices of potential life lost to quantify future impacts on society of particular causes of death. These indices also properly reflect the effects of competing risks. The computation is simple, requiring no more than a standard life-table calculation. Real-world as well as hypothetical data are used to illustrate the method. RESULTS: The new indices convey valuable health status information about a population that is not revealed by traditional indices. CONCLUSIONS: The new indices are promising alternatives as measures of future potential life lost.

Hypertensive black men and women. Quality of life and effects of antihypertensive medications. Black Hypertension Quality of Life Multicenter Trial Group.

A multicenter, randomized double-blind clinical trial was conducted among 306 black men and women with mild to moderate hypertension to determine effects of atenolol, captopril, and verapamil SR on measures of quality of life. Patients were randomly assigned to a stable or forced-dose titration sequence. After an 8-week treatment period, the rate of withdrawal from treatment because of adverse effects was low and did not differ by drug treatment group or titration level. Patients taking verapamil SR showed a significantly greater reduction in mean blood pressures than patients treated with atenolol or captopril. Along with absence of worsening on any quality of life total scale scores examined over the treatment period, we found either improvement or no change in the total scale scores for all three treatment groups. Among both male and female patients, comparisons between drug treatment groups showed no differences in degree of change on the total scale scores. In comparisons within each treatment group, improvement in scores of male patients after 8 weeks appeared among those taking atenolol in general well-being and physical symptoms reduction; among male patients taking captopril in general well-being, physical symptoms, and sexual performance; and among male patients receiving verapamil SR in scores in irritability, sleep, and the Digit Span test. Improvement in scores among female patients taking atenolol was found in scores on general well-being, physical symptoms, and sleep; among women taking captopril on general well-being, physical symptoms, and irritability; and among women taking verapamil SR on general well-being. Patients in all treatment groups improved on measures of visuomotor functioning. The research shows that with the three newer generation antihypertensive medications studied, blood pressure control was achieved during the treatment period without negative effects on quality of life scales, along with findings of improvement on some measures. Given the special clinical features of hypertension in black patients, the study underlines as well the potential and utility of systematic tracking of measures of quality of life, while monitoring blood pressures in this patient population.

Assessing quality of life in patients with head and neck cancer: cross-validation of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Head and Neck module (QLQ-H&N35).

OBJECTIVE: To evaluate the reliability and validity of a new, disease-specific quality-of-life measure for patients with head and neck cancer: the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire--QLQ-H&N35. DESIGN: Cross-sectional study using questionnaire data and medical chart review. SETTING: Academic tertiary care otolaryngology clinic. PARTICIPANTS: One hundred twenty ambulatory patients, including 30 patients with advanced head and neck cancer in each of the following stages of treatment: (1) prior to treatment, (2) during active treatment, (3) within 6 months of completing treatment, and (4) more than 6 months after completing treatment. In addition, (5) a comparison group of 40 patients without malignant disease was included (total sample, N = 160). MAIN OUTCOME MEASURES: Scores on EORTC Quality of Life Core Questionnaire (QLQ-C30) and head and neck module (QLQ-H&N35), Profile of Mood States, and Impact of Events Scale. RESULTS: The QLQ-H&N35 demonstrated acceptable reliability (internal consistency). It successfully discriminated between cancer patients and the comparison group, and among subgroups of cancer patients at different phases of treatment (construct validity). The instrument was sensitive to the effects of radiation treatment and to site of disease. Its low-to-moderate correlations with the EORTC core questionnaire indicated that the QLQ-H&N35 provided unique information (discriminant validity). Scores were significantly associated with a number of demographic variables. CONCLUSION: Results support the use of this disease-specific measure to assess quality of life among patients with advanced head and neck cancer.

Antiquity of postreproductive life: are there modern impacts on hunter-gatherer postreproductive life spans?

Female postreproductive life is a striking feature of human life history and there have been several recent attempts to account for its evolution. But archaeologists estimate that in the past, few individuals lived many postreproductive years. Is postreproductive life a phenotypic outcome of modern conditions, needing no evolutionary account? This article assesses effects of the modern world on hunter-gatherer adult mortality, with special reference to the Hadza. Evidence suggests that such effects are not sufficient to deny the existence of substantial life expectancy at the end of the childbearing career. Data from contemporary hunter-gatherers (Ache, !Kung, Hadza) match longevity extrapolated from regressions of lifespan on body and brain weight. Twenty or so vigorous years between the end of reproduction and the onset of significant senescence does require an explanation.

Studying the quality of life and life satisfaction among persons with spinal cord injury undergoing urinary management.

The purpose of this survey was to investigate quality of life and life satisfaction among persons with spinal cord injury (SCI) who require various types of urinary management. A sample of 230 persons with SCI completed the Quality of Life Index (QLI), the Satisfaction With Life Scale (SWLS), and a demographic data form. Findings of this study indicated that there was no significant difference in QLI and SWLS with regard to the type of urinary management used (reflex voiding, indwelling catheter, suprapubic catheter, intermittent catheterization, external catheter or a combination of intermittent catheterization and external catheter). There also was no significant difference in QLI and SWLS with regard to the level of SCI or the incidence of hospitalizations for urinary infections. There were significantly higher QLI and SWLS scores for those with greater abilities to work, attend school, and participate in activities. There also was a significantly higher QLI for those without skin problems associated with urinary dysfunction.

[Quality of life in skin diseases: methodological and practical comparison of different quality of life questionnaires in psoriasis and atopic dermatitis].

Aim of the present study was a comparison of four quality of life (QoL) questionnaires in 228 patients with psoriasis (PSO, n = 148) and atopic dermatitis (AD, n = 80) regarding feasibility, discriminant validity and sensitivity to change. Evaluating were performed before and after treatment in clinic. The following questionnaires were compared. 1) Freiburg Quality of Life Assessment for Dermatoses (FLQA-d), 2) Dermatology Life Quality Index (DLQI), 3) Chronic Skin Disease Questionnaire (CSDQ) and 4) questionnaire on everyday life (ALLTAG). All questionnaires were able to discriminate significant reductions of QoL in PSO and AD, as compared to controls. In parallel to the clinical improvement, all questionnaires showed QoL improvements as well, i.e. the questionnaires were sensitive to change. However, not all of the DLQI and ALLTAG scales were sensitive to change. Also, in some cases part of the scales of these questionnaires could not be calculated due to missing data. Otherwise, all questionnaires were valid and easy to handle. Thus, QoL of patients with PSO and AD can reliably be assessed by various questionnaires. Decisive for selection are the aim and the design of the study.

Quality of life and factors related to perceived satisfaction with quality of life after allogeneic bone marrow transplantation.

The quality of life after bone marrow transplantation (BMT) was studied in 109 adult allogeneic BMT recipients transplanted on at the Helsinki University Central hospital for a haematological malignancy. Physical, functional, emotional and social well-being was measured on the Functional Assessment of Cancer Therapy Scale (FACT-BMT) and a shortened version of the Profile of Mood States Scale (POMS) and by the MOS social support survey and a Brief Measure of Social Support (SSQ6). The results of the present study replicate those of previous investigations by finding that physical well-being, educational level, age at BMT and social support have an impact on the perceived quality of life of BMT patients. Our results indicate that these factors have a varying impact at different time points during the post-BMT recovery process. During the first three years after BMT, physical well-being proved to be a highly significant (P < 0.001) factor for perceived life satisfaction. Moreover, physical well-being showed an average significant improvement after the first post-BMT year. The percentage of the recipients experiencing the highest levels of satisfaction with life increased from 51% during the first year after BMT to 81% for those patients five years post-BMT. One year after BMT, 75.6% of the BMT recipients were able to work, 67.8% of the patients were actively participating in work/school and 7.8% were unemployed.

[The Heidelberg instrument for the assessment of quality of life in dementia (H. I. L. DE.)--dimensions of quality of life and methods of organization].

The contribution is intended to describe the theoretical background and measurement approach of H.I.L.DE., a research project aimed to develop and validate a comprehensive assessment of quality of life in nursing home residents suffering from dementia. Proceeding from the assumption that emotions are felt even in advanced stages of dementia and can be interpreted on the basis of peoples' mimic expressions, three samples of participants were recruited from 11 nursing homes of varying maintenance: 121 nursing home residents suffering from dementia, 97 professional caregivers and 101 relatives participated in the first wave of this study. Operational definition of quality of life in H.I.L.DE. proceeds from the differentiation of eight dimensions of quality of life: physical environment, social environment, quality of care, behavioral competence, medical and functional status, cognitive status, psychopathology and behavior disturbances, and subjective experiences of physical and social environment and emotional well-being. Measures of the eight dimensions involve data from medical examination, interviews with residents, professional caregivers and relatives, ecopsychological assessment of physical environment and analysis of care documents. First results from the H.I.L.DE.-study are used as an illustration of the potentials of such a comprehensive approach to the measurement of quality of life.

[On quality of life after surgical therapy of oral cancer - a retrospective multi-center study: the connection between dedentition, denture, quality of life, and dysphagia, and the resulting rehabilitation schemes].

PURPOSE: The surgical treatment of oral cancer results in functional and aesthetical impairments. Patients' quality of life is considerably impaired by oral symptoms resulting from therapy of oral cancer. In many cases the inevitable resection of the tumor, as well as the adjuvant radiochemotherapy will cause the destruction of physiologically and anatomically important structures. One focus of research was the specific rehabilitation of dental loss by functional dentures. Another was the course of 19 impairments (comprehension of speech for unknown others, comprehension of speech for familiar others, eating/swallowing, mobility of the tongue, opening range of the mouth, mobility of lower jaw, mobility of neck, mobility of arms and shoulders, sense of taste, sense of smell, appearance, strength, appetite, respiration, pain, swelling, xerostomia, halitosis). METHODS: Commissioned by the German, Austrian and Swiss cooperative group on tumors of the maxillofacial region (DOSAK), data were collected in 3.894 questionnaires at 43 hospitals in Germany, Austria and Switzerland. The catalogue comprised 147 items in 9 chapters. At the end of the enquiry, 1.761 anonymous questionnaires were returned by 38 hospitals. 1.652 of these could be evaluated regarding the question. RESULTS: The sum score of the 19 impairments was highly increased immediately after the operation and recovered over the next 6 months, without, however, reaching the pre-surgery level. Of 1.652 patients, only 35% did not lose any teeth during therapy. 23% lost up to 5, 17% up to 10 teeth. A quarter of the patients lost more than 10 teeth. The more teeth were lost, the greater the decline of quality of life (p < or = 0.001), although this could be allayed by the functionality of the dentures (p < or = 0.001). There is a reciprocal dependence between the functionality of dental prosthetics and impairment by eating/swallowing (p < or = 0.001). CONCLUSIONS: Patients' quality of life after radical surgery of a carcinoma of the oral cavity depends not only on the functionality of dentures and the specificity of rehabilitation, but also from the initial findings, the extent and location of the resection, the chosen therapy, the general circumstances of the patient's life as well as their strategies of coping. These factors, however, unlike those of functionality of dental prosthesis and rehabilitation, are not modifiable.

The Life Engagement Test: assessing purpose in life.

This article describes a 6-item scale, the Life Engagement Test, designed to measure purpose in life, defined in terms of the extent to which a person engages in activities that are personally valued. Psychometric data are presented including information about the scale's factor structure, internal consistency, test-retest reliability, convergent validity, discriminant predictive validity, and norms. The data suggest that the Life Engagement Test is psychometrically sound across different gender, age, and ethnic groups and is appropriate for wider use. Discussion centers on the use of the Life Engagement Test in behavioral medicine and health psychology research and recent associations that have begun to emerge between the scale and health-relevant outcomes.

Predictors of quality of life in HIV-infected rural women: psychometric test of the chronic illness quality of life ladder.

The Chronic Illness Quality of Life Ladder (CIQOLL) underwent psychometric testing in a sample of 278 women with HIV disease. The CIQOLL, a self-anchoring striving scale based on Cantril's Ladder, measures seven domains (physical , emotional, financial, family and friends, spiritual well-being, peace of mind, and overall life satisfaction) across four time periods (present, past, future, life without a diagnosis of HIV). The domains were derived from focus groups with persons with HIV disease. Women with a diagnosis of HIV Infection, age 18 or older, residing in rural areas in the southeastern United States, completed questionnaires that measured physical functioning, HIV related symptom frequency and distress, depressive symptoms, social support, and quality of life. Procedures used to assess reliability included item-item, item-total, and subscale-subscale correlations, and Chronbach's coefficient alpha. Criterion-related (concurrent) validity was assessed by correlating the CIQOLL with HIV symptoms, functional status and social support. Construct validity was estimated using factor analysis and predictive modeling. Results provide preliminary evidence that the CIQOLL is a reliable and valid scale that may provide meaningful information about persons living with a chronic illness, such as HIV disease, especially low literacy and unacculturated populations. Additional research is needed to weight the domains, test the sensitivity of the scale to changes over time, and explore the usefulness of discrepancy scores.

Reliability of life event assessments: test-retest reliability and fall-off effects of the Munich Interview for the Assessment of Life Events and Conditions.

This paper presents the findings of two independent studies which examined the test-retest reliability and the fall-off effects of the Munich Life Event List (MEL). The MEL is a three-step interview procedure for assessing life incidents which focuses on recognition processes rather than free recall. In a reliability study, test-retest coefficients of the MEL, based on a sample of 42 subjects, were quite stable over a 6-week interval. Stability for severe incidents appeared to be higher than for the less severe ones. In the fall-off study, a total rate of 30% fall-off was noted for all incidents reported retrospectively over an 8-year period. A more detailed analysis revealed average monthly fall-off effects of 0.36%. The size of fall-off effects was higher for non-severe and positive incidents than for severe incidents. This was particularly evident for the symptomatic groups. Non-symptomatic males reported a higher overall number of life incidents than females. This was partly due to more frequent reporting of severe incidents. The findings of the fall-off study do not support the common belief that the reliability of life incident report is much worse when the assessment period is extended over a period of several years as compared to the traditional 6-month period.

Life events and biological vulnerability: a study of life events and platelet MAO activity in depressed patients.

The present study investigated the possible relationship between platelet monoamine oxidase (MAO) activity and life events. From the general hypothesis that the impact of life events should be seen against the background of an individual's vulnerability, it was assumed that low platelet MAO patients would need fewer life events to develop a psychopathological condition and that they would experience more negatively those events that occurred. Patients (n = 127) of both sexes suffering from various kinds of depressive disorders participated in the study. There were 39 unipolar patients, 11 bipolar patients, 43 patients suffering from neurotic-reactive disorder, and 34 patients suffering from an unspecified depressive disorder. No statistically significant differences in MAO activity were found in this series among the diagnostic subgroups. Younger patients predominated among those with the lowest MAO values. As expected, low MAO patients reported a lower number of life events than patients in the highest MAO quartile, and had experienced those events more negatively.

The fundamental chemistry of life. An attempt to define and identify the basic reaction responsible for life's creation and evolution.

All natural growth follows exponential characteristics which vary from a simple exponential equation (non-solid cancer, bacteria) to complex Gompertzian functions describing solid cancer and multicellular organisms. Like all chemical processes the reagents (energy sources of food) react during life to produce vital energy, but in addition also create the next generation of life. This latter reaction is unique in that a simple proportional increase in the reagents creates an exponential increase in products: it is the sole invariable criterion of all life. The target of combined ionising and non-ionising radiations in cancer cells appears to be identical with this fundamental exponential chemical reaction. Identification of this target as a system of anaerobic glycolysis suggests that life's first reaction is a unique one whereby a simple proportional increase in available glucose causes an exponential proportional increase in energy which is available solely for reproduction.
