Objective To assess health-related quality of life (HRQOL) in a prospective study with 7 years of follow-up in 49 consecutive patients who underwent a total joint replacement because of osteoarthritis. Methods Generic HRQOL was assessed with the shortform 36 (SF-36) and specific HRQOL with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results Out of the 39 subjects who have completed the 7 years of follow-up of this study, 22 (56.4 %) underwent a hip replacement surgery and the other 17 (43.6 %) a knee replacement. Six months after surgery, a significant improvement, compared to preoperative scores, was observed in two of the eight dimensions of the SF-36 (i.e. physical function and pain). The same dimensions, pain and physical function, at the same time, 6 months after surgery, measured by the WOMAC, showed a significant improvement as well, but there was no significant change in the stiffness score. From 6 months to the end of followup, changes in SF-36 scores showed a significant improvement in physical function (p = 0.008), role-physical (p = 0.004) and role-emotional (p = 0.01) while all scores of the WOMAC improved (p\0.001 for pain, p\0.001 for stiffness and p\0.01 for physical function). Conclusion The improvements observed in HRQOL at short term after surgery, are at least maintained over a 7-year follow-up period. [less ▲]

The objective was to quantify the outcome of osteoporosis (OP) in terms of health-related quality of life (HR-QOL) and cost of ambulatory care and to look at the association between these two outcomes variables. A cross-sectional health survey of 4800 Belgian individuals over the age of 45 years was used. Individuals having reported OP were retrieved and for each of them, at least two matched individuals for age, sex, residency location, and health insurance status were identified. All individuals were assessed with the SF-36. The two major health insurance providers furnished cost value for ambulatory care. HR-QOL and cost data were compared between the OP group and control group. Beta-coefficients from linear regression were calculated to give information on the relative importance of the association between each SF-36 dimensions and cost of ambulatory care. Of 4796 individuals appropriately surveyed, 221 (4.8%) reported OP. The control group included 651 individuals. The OP group experienced impaired HR-QOL compared to their matched counterparts, all the difference in mean or median SF-36 scores being significant at the level of P < 0.001. Osteoporotic respondents averaged 816 in cost of ambulatory care whereas controls averaged 579 (P < 0.001). When looking at detailed comparisons between categories of cost, costs in the OP group far exceeded those in the control group, all the differences being significant at the level of P < 0.001 except for home health nurse (P = 0.012). In the OP group, vitality dimensions played the most important role in the determination of cost (beta = -0.28, P < 0.001), followed by physical functioning (beta = -0.26, P < 0.01), general health, and social functioning (beta = -0.23, P < 0.01). This study evidences the burden of OP in terms of HR-QOL and cost of ambulatory care. Exploring the association between HR-QOL and cost show that mental dimension such as vitality can play an important role in the determination of cost. Conclusively, they should not be neglected in future management of OP. [less ▲]

BACKGROUND: Total hip and total knee arthroplasties are well accepted as reliable and suitable surgical procedures to return patients to function. Health-related quality-of-life instruments have been used to document outcomes in order to optimize the allocation of resources. The objective of this study was to review the literature regarding the outcomes of total hip and knee arthroplasties as evaluated by health-related quality-of-life instruments. METHODS: The Medline and EMBASE medical literature databases were searched, from January 1980 to June 2003, to identify relevant studies. Studies were eligible for review if they met the following criteria: (1). the language was English or French, (2). at least one well-validated and self-reported health-related quality of life instrument was used, and (3). a prospective cohort study design was used. RESULTS: Of the seventy-four studies selected for the review, thirty-two investigated both total hip and total knee arthroplasties, twenty-six focused on total hip arthroplasty, and sixteen focused on total knee arthroplasty exclusively. The most common diagnosis was osteoarthritis. The duration of follow-up ranged from seven days to seven years, with the majority of studies describing results at six to twelve months. The Short Form-36 and the Western Ontario and McMaster University Osteoarthritis Index, the most frequently used instruments, were employed in forty and twenty-eight studies, respectively. Seventeen studies used a utility index. Overall, total hip and total knee arthroplasties were found to be quite effective in terms of improvement in health-related quality-of-life dimensions, with the occasional exception of the social dimension. Age was not found to be an obstacle to effective surgery, and men seemed to benefit more from the intervention than did women. When improvement was found to be modest, the role of comorbidities was highlighted. Total hip arthroplasty appears to return patients to function to a greater extent than do knee procedures, and primary surgery offers greater improvement than does revision. Patients who had poorer preoperative health-related quality of life were more likely to experience greater improvement. CONCLUSIONS: Health-related quality-of-life data are valuable, can provide relevant health-status information to health professionals, and should be used as a rationale for the implementation of the most adequate standard of care. Additional knowledge and scientific dissemination of surgery outcomes should help to ensure better management of patients undergoing total hip or total knee arthroplasty and to optimize the use of these procedures.

Purpose The purpose of this research was to evaluate whether baseline health-related quality of life (HRQOL) parameters are prognostic factors for survival in locally advanced breast cancer patients. Although the literature highlights the important role of HRQOL parameters in predicting survival in advanced metastatic disease, little evidence exists for earlier stages. Patients and Methods The overall sample consisted of 448 patients randomly assigned to receive cyclophosphamide, epirubicin, and fluorouracil versus epirubicin, cyclophosphamide, and granulocyte colony-stimulating factor. Patients were enrolled in 12 countries. HRQOL baseline scores were assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30. The Cox proportional hazards regression model was used for both univariate and multivariate analyses of survival. In addition, a bootstrap resampling technique was used to assess the stability of the outcomes. Bootstrap results were then applied for model averaging purposes as a means to account for the observed model selection uncertainty. Results The final multivariate model retained inflammatory breast cancer (T4d) as the only factor predicting overall survival (OS) with a hazard ratio of 1.375 (95% CI, 1.027 to 1.840; P = .03). The presence of inflammatory breast cancer lowers the median survival time from 6.6 to 4.2 years (36% reduction). None of the preselected HRQOL variables were prognostic for OS or disease-free survival, in either the univariate or multivariate analysis. Conclusion Our findings suggest that baseline HBQOL parameters have no prognostic value in a nonmetastatic breast cancer population. [less ▲]

The aim of this study was to compare the socioeconomic consequences of early and late rheumatoid arthritis in Belgium and to assess the patient out-of-pocket contributions. This multicentre longitudinal study in Belgium evaluated patients with rheumatoid arthritis. Early disease was defined as diagnosis since less than 1 year. At baseline sociodemographic and disease characteristics were assessed and during the following year patients recorded all healthcare- and non-healthcare-related direct costs and out-of-pocket contributions. The study included 48 patients with early and 85 patients with late rheumatoid arthritis. Mean disease duration was 0.5 vs 12.5 years in patients with early and late rheumatoid arthritis, respectively. The disease activity score (DAS28) was comparable between both groups (4.1 vs 4.5, p=0.14), but physical function (Health Assessment Questionnaire, HAQ) was more impaired in patients with long-standing disease (1.0 vs 1.7, p < 0.001). Work disability had increased from 2% in patients with early to 18% in patients with late disease. The annual societal direct costs per patient were E 3055 (median: E 1518) opposed to E 9946 (median: E 4017) for early and late rheumatoid arthritis, respectively. The higher direct cost for patients with long-standing disease was seen for all categories, but especially for physiotherapy and need for devices and adaptations. Patients with early as well as late disease contribute out of pocket about one-third to the direct healthcare costs. Within each group, HAQ was a strong determinant of costs. In Belgium, patients with long-standing rheumatoid arthritis are nine times more likely to be work disabled than patients with less than 1 year disease duration and have a threefold increase in costs. Differences in healthcare consumption between patients could be mainly explained by differences in physical function (HAQ). [less ▲]

The air-filled swimbladder acts as an acoustic amplifier for some fish by converting sound pressure into particle motion, which is transmitted to the inner ear. Here, we describe in detail the specialized connection between the swimbladder and ear in the mojarra, as well as a modified cone on the anal fin in which the posterior end of the swimbladder sits. Hearing tests show the mojarra has better hearing sensitivity than other species of fish without a connection. However, mojarras do not seem to use this adaptation for communication. Furthermore, the inclined position of the swimbladder may help the fish to catch their prey more easily, as the swimbladder will be horizontal when they are picking up benthic prey. [less ▲]

Insertion of an electrode array into the cochlea produces immediate damage to the inner ear, which is responsible for a hearing loss. In addition, a delayed hearing loss can be observed. In order to maximize hearing preservation after insertion of an electrode and to enhance the performance of the cochlear implant, it has been proposed to deliver pharmacological agents to the inner ear. Molecules can be administered locally to the inner ear through a direct perilymphatic perfusion or through the round window membrane. These modalities of treatment have already been successfully applied to some patients with inner ear diseases. In this paper, we will review some basic aspects of drug delivery to the inner ear to prevent the degeneration of the neurosensory hair cells and auditory neurons, and the actual applicability to humans in order to maintain hearing function after the insertion of electrodes of a cochlear implant.

On the basis of transfection experiments using a dominant-negative approach, our previous studies suggested that PKB (protein kinase B) was not involved in heart PFK-2 (6-phosphofructo2-kinase) activation by insulin. Therefore we first tested whether SGK3 (serum- and glucocorticoid-induced protein kinase 3) might be involved in this effect. Treatment of recombinant heart PFK-2 with [gamma-32P]ATP and SGK3 in vitro led to PFK-2 activation and phosphorylation at Ser466 and Ser483. However, in HEK-293T cells [HEK (human embryonic kidney)-293 cells expressing the large T-antigen of SV40 (simian virus 40)] co-transfected with SGK3 siRNA (small interfering RNA) and heart PFK-2, insulin-induced heart PFK-2 activation was unaffected. The involvement of PKB in heart PFK-2 activation by insulin was re-evaluated using different models: (i) hearts from transgenic mice with a muscle/heart-specific mutation in the PDK1 (phosphoinositide-dependent protein kinase 1)-substrate-docking site injected with insulin; (ii) hearts from PKBbeta-deficient mice injected with insulin; (iii) freshly isolated rat cardiomyocytes and perfused hearts treated with the selective Akti-1/2 PKB inhibitor prior to insulin treatment; and (iv) HEK-293T cells co-transfected with heart PFK-2, and PKBalpha/beta siRNA or PKBalpha siRNA, incubated with insulin. Together, the results indicated that SGK3 is not required for insulin-induced PFK-2 activation and that this effect is likely mediated by PKBalpha. [less ▲]
