To compare the value of clinically measured gait speed with that of the self-reported Medical Outcomes Study 36-item Short-Form Survey Physical Function Index (SF-36 PF) in predicting future preclinical mobility disability (PCMD) in older women. Prospective cohort study. Forty clinical centers in the United States. Women aged 65 to 79 enrolled in the Women's Health Initiative Clinical Trials with gait speed and SF-36 assessed at baseline (1993-1998) and follow-up Years 1, 3, and 6 (N = 3,587). Women were categorized as nondecliners or decliners based on changes (from baseline to Year 1) in gait speed and SF-36 PF scores. Logistic regression models were used to estimate incident PCMD (gait speed 36 PF with that of measured gait speed. Slower baseline gait speed and lower SF-36 PF scores were associated with higher adjusted odds of PCMD at Years 3 and 6 (all P 36, decliners were 1.42 times as likely to have developed PCMD by Year 3 and 1.49 times as likely by Year 6. Baseline gait speed (AUC = 0.713) was nonsignificantly better than SF-36 (AUC = 0.705) at predicting PCMD over 6 years (P = .21); including measures at a second time point significantly improved model discrimination for predicting PCMD (all P 36 PF did, although the results may be limited given that gait speed served as a predictor and to define the PCMD outcome. Nonetheless, monitoring trajectories of change in mobility are better predictors of future mobility disability than single measures. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

The Short Form 36 (SF-36) is one of the most widely used generic health status measure. This study used the SF-36 Health Survey instrument to investigate the functional health and well-being of Malay Type 2 Diabetes Mellitus patients in Malaysia. The survey was carried out in three local hospitals in Selangor. The method of questionnaire administration was both self-administered and interviewer administered. A total of 354 questionnaires was returned, but only 295 questionnaires with no missing data were analyzed. Confirmatory Factor Analysis (CFA) was used to confirm the first-order and third-order CFA models. The higher order analyses included a third-order CFA models with two second-order factors (physical and mental component) and three second-order factors (physical, general well-being and mental health) and both showed satisfactory model fit indices. This study confirmed the multidimensional factor structure of the SF-36.

To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects. To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach's α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed. We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, pPortuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients' psychological adaptations that minimized the impact of ED on Quality of Life (QoL) and reestablished the well-being feeling.

To examine the associations of mental health functioning with intentions to retire early among ageing municipal employees. Cross-sectional survey data (n = 7,765) from the Helsinki Health Study in 2000, 2001, and 2002 were used. Intentions to retire early were sought with a question: "Have you considered retiring before normal retirement age?" The dependent variable was divided into three categories: 1 = no intentions to retire early; 2 = weak intentions; 3 = strong intentions. Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Other variables included age, sex, physical health functioning (SF-36), limiting longstanding illness, socioeconomic status, and spouse's employment status. Multinomial regression analysis was used to examine the association of mental health functioning with intentions to retire early. Employees with the poorest mental health functioning were much more likely to report strong intentions to retire early (OR 6.09, 95% CI 4.97-7.47) than those with the best mental health functioning. Adjustments for physical health, socioeconomic status, and spouse's employment status did not substantially affect this association. The findings highlight the importance of mental health for intentions to retire early. Strategies aimed at keeping people at work for longer should emphasize the importance of mental well-being and the prevention of poor mental health. More evidence is needed on why mental problems among ageing baby-boomer employees are giving rise to increasing social consequences, although the overall prevalence of mental problems has not increased.

Full Text Available Abstract Background The Medical Outcomes General Health Survey (SF-36 is a widely used health status measure; however, limited evidence is available for its performance in orthopedic settings. The aim of this study was to examine the magnitude and meaningfulness of change and sensitivity of SF-36 subscales following orthopedic surgery. Methods Longitudinal data on outcomes of total hip replacement (THR, n = 255, total knee replacement (TKR, n = 103, arthroscopic partial meniscectomy (APM, n = 74 and anterior cruciate ligament reconstruction (ACL, n = 62 were used to estimate the effect sizes (ES, magnitude of change and minimal detectable change (sensitivity at the group and individual level. To provide context for interpreting the magnitude of changes in SF-36 scores, we also compared patients' scores with age and sex-matched population norms. The studies were conducted in Sweden. Follow-up was five years in THR and TKR studies, two years in ACL, and three months in APM. Results On average, large effect sizes (ES≥0.80 were found after orthopedic surgery in SF-36 subscales measuring physical aspects (physical functioning, role physical, and bodily pain. Small (0.20–0.49 to moderate (0.50–0.79 effect sizes were found in subscales measuring mental and social aspects (role emotional, vitality, social functioning, and mental health. General health scores remained relatively unchanged during the follow-up. Despite improvements, post-surgery mean scores of patients were still below the age and sex matched population norms on physical subscales. Patients' scores on mental and social subscales approached population norms following the surgery. At the individual level, scores of a large proportion of patients were affected by floor or ceiling effects on several subscales and the sensitivity to individual change was very low. Conclusion Large to moderate meaningful changes in group scores were observed in all SF-36 subscales except General Health

This review is the first to evaluate the burden of ulcerative colitis [UC] on patients' quality of life by synthesizing data from studies comparing scores from the SF-36® Health Survey, a generic measure assessing eight quality-of-life domains, between UC patients and matched reference samples. A systematic review of the published literature identified articles reporting SF-36 domains or physical and mental component summary scores [PCS, MCS] from UC and reference samples. Burden of disease for each SF-36 domain was then summarized across studies by comparing weighted mean differences in scores between patient and reference samples with minimally important difference thresholds. Thirty articles met pre-specified inclusion criteria. SF-36 scores were extracted from five samples of patients with active disease, 11 samples with a mixture of disease activity, five samples of patients in clinical remission, and 13 samples of patients following proctocolectomy with ileostomy or ileal pouch-anal anastomosis, along with respective reference samples. Clinically meaningful burden was observed in samples with active or mixed disease activity [deficits: PCS = 5.6, MCS = 5.5] on all SF-36 domains except Physical Functioning. No burden was observed in samples in remission or post-surgical patients [deficits: PCS = 0.8, MCS = 0.4] except for the General Health perception domain. Patients with active UC experience a clinically meaningful burden of disease across most aspects of quality of life. Patients with inactive UC exhibit negligible disease burden and are comparable to the general population on most quality-of-life outcomes. Thus, treatments which effectively induce and maintain remission may restore physical and mental health status.

The aim of this study was to examine if using orthogonal and oblique factor analysis detect changes in health-related quality of life differently in diabetic patients on the Short Form-36 (SF-36) survey. A total of 155 patients had diabetic foot complications (DFC), and 145 patients had no DFCs. The SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were calculated using scoring coefficients determined by orthogonal and oblique rotation principle component analyses of the subscales. The DFC group had lower orthogonal ( P < .00001) and oblique PCS scores ( P < .00001). However, despite lower Mental Health subscale scores in the patients with DFCs, orthogonal MCS scores ( P = .156) did not differ. In contrast, the oblique MCS scores reflected the difference in the Mental Health subscale ( P = .0005). Orthogonal and oblique PCS scores did not differ significantly. However, orthogonal MCS scores were significantly higher than oblique MCS scores in those with DFCs ( P = .0004) and without DFCs ( P = .005). The shorter, 12-item SF-12 survey demonstrated similar results. Poorer physical function leads to higher orthogonal MCS scores than if determined by oblique scoring coefficients since Physical Function, Bodily Pain, and General Health are weighted more negatively in orthogonal coefficients when calculating the MCS score. Oblique scoring coefficients may address this issue, but further study is necessary to confirm whether oblique MCS scores accurately represent the mental health of patients with diabetic foot disease.

To test psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0) in Chinese mainland patients with methadone maintenance treatment (MMT). A total of 1,212 patients were recruited from two MMT clinics in Xi'an, China. Reliability was estimated with Cronbach's α and intra-class correlation (ICC). Convergent and discriminant validity was assessed using multitrait-multimethod correlation matrix. Sensitivity was measured with ANOVA and relative efficiency. Responsiveness was evaluated by pre-post paired-samples t-test and standardized response mean based on the patients' health status changes following 6-month period. Cronbach's α of the SF-36v2 physical and mental summary components were 0.80 and 0.86 (eight scales range 0.73-0.92) and the QOL-DAv2.0 was 0.96 (four scales range: 0.80-0.93). ICC of the SF-36v2 two components were 0.86 and 0.85 (eight scales range: 0.72-0.87) and the QOL-DAv2.0 was 0.94 (four scales range: 0.88-0.92). Convergent validity was lower between the two instruments (γ <0.70) while discriminant validity was acceptable within each instrument. Sensitivity was satisfied in self-evaluated health status (both instruments) and average daily methadone dose (SF-36v2 physical functioning and vitality scales; QOL-DAv2.0 except psychology scale). Responsiveness was acceptable in the improved health status change (SF-36v2 except vitality scale; QOL-DAv2.0 except psychology and symptoms scales) and deteriorated health status change (SF-36v2 except vitality, social functioning and mental health scales; QOL-DAv2.0 except society scale). The SF-36v2 and the QOL-DAv2.0 are valid tools and can be used independently or complementary according to different emphases of health-related quality of life evaluation in patients with MMT.

We examined whether women with polycystic ovary syndrome (PCOS) have poorer health-related quality of life (HRQoL) than women in the general population and than patients with other medical conditions. Women with PCOS were recruited from an outpatient clinic and a control group was recruited from a family planning clinic. Both groups completed the Short Form-36 (SF-36) and the Polycystic Ovary Syndrome Questionnaire (PCOSQ). SF-36 data from the Oxford Health and Lifestyle Survey were used to compare PCOS with other conditions. Twenty-two women with PCOS and 96 control women took part. Women with PCOS scored lower in both summary scores of the SF-36 and in all domains of the PCOSQ. After adjusting for body mass index, the differences between the groups in the SF-36 disappeared, while those in the PCOSQ remained. When compared with asthma, epilepsy, diabetes, back pain, arthritis and coronary heart disease, our PCOS group had the same or better physical HRQoL but poorer psychological HRQoL. The PCOSQ showed good internal reliability, good concurrent validity and good discriminant validity. PCOS has a negative impact on HRQoL even when compared with other serious health conditions. The PCOSQ is reliable and valid for clinical use.

Full Text Available Abstract Background Cost utility analysis (CUA using SF-36/SF-12 data has been facilitated by the development of several preference-based algorithms. The purpose of this study was to illustrate how decision-making could be affected by the choice of preference-based algorithms for the SF-36 and SF-12, and provide some guidance on selecting an appropriate algorithm. Methods Two sets of data were used: (1 a clinical trial of adult asthma patients; and (2 a longitudinal study of post-stroke patients. Incremental costs were assumed to be $2000 per year over standard treatment, and QALY gains realized over a 1-year period. Ten published algorithms were identified, denoted by first author: Brazier (SF-36, Brazier (SF-12, Shmueli, Fryback, Lundberg, Nichol, Franks (3 algorithms, and Lawrence. Incremental cost-utility ratios (ICURs for each algorithm, stated in dollars per quality-adjusted life year ($/QALY, were ranked and compared between datasets. Results In the asthma patients, estimated ICURs ranged from Lawrence's SF-12 algorithm at $30,769/QALY (95% CI: 26,316 to 36,697 to Brazier's SF-36 algorithm at $63,492/QALY (95% CI: 48,780 to 83,333. ICURs for the stroke cohort varied slightly more dramatically. The MEPS-based algorithm by Franks et al. provided the lowest ICUR at $27,972/QALY (95% CI: 20,942 to 41,667. The Fryback and Shmueli algorithms provided ICURs that were greater than $50,000/QALY and did not have confidence intervals that overlapped with most of the other algorithms. The ICUR-based ranking of algorithms was strongly correlated between the asthma and stroke datasets (r = 0.60. Conclusion SF-36/SF-12 preference-based algorithms produced a wide range of ICURs that could potentially lead to different reimbursement decisions. Brazier's SF-36 and SF-12 algorithms have a strong methodological and theoretical basis and tended to generate relatively higher ICUR estimates, considerations that support a preference for these algorithms over the

DYNHA SF-36 is a computerized adaptive test version of the SF-36 Health Survey. The feasibility of administering a modified DYNHA SF-36 to adults with HIV was evaluated with Johns Hopkins University Moore (HIV) Clinic patients (N=100) and Internet consumer health panel members (N=101). Participants completed the DYNHA SF-36, modified to capture seven health domains [(physical function (PF), role function (RF, without physical or emotional attribution), bodily pain (BP), general health, vitality (VT), social function (SF), mental health (MH)], and scored to produce two summary components [Physical Component Summary (PCS), Mental Component Summary (MCS)]. Item-response theory-based response consistency, precision, mean scores, and discriminant validity were examined. A higher percentage of Internet participants responded consistently to the DYNHA SF-36. For each domain, three standard deviations were covered with five items (90% reliability); however, RF and SF scores were less precise at the upper end of measurement (better functioning). Mean scores were slightly higher for the Internet sample, with the exception of VT and MCS. Clinic and Internet participants reporting an AIDS diagnosis had significantly lower mean PCS and PF scores than those without a diagnosis. Additionally, significantly lower RF and BP scores were found for Internet participants reporting an AIDS diagnosis. The measure was well accepted by the majority of participants, although Internet respondents provided lower ratings for the tool's usefulness. The DYNHA SF-36 has promise for measuring the impact of HIV and its treatment in both the clinic setting and through telemonitoring.

To examine the associations of mental health functioning (SF-36) and work and family related psychosocial factors with intentions to retire early. Cross sectional survey data (n = 5037) from the Helsinki Health Study occupational cohort in 2001 and 2002 were used. Intentions to retire early were inquired with a question: "Have you considered retiring before normal retirement age?" Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Work and family related psychosocial factors included job demands and job control, procedural and relational justice, conflicts between work and family, and social network size. Multinomial regression models were used to analyse the data. Poor mental health functioning, unfavourable psychosocial working conditions, and conflicts between work and family were individually related to intentions to retire early. After adjustments for all work and family related factors the odds ratio for low mental health functioning was halved (from OR = 6.05 to 3.67), but nevertheless the association between poor mental health functioning and strong intentions to retire early remained strong. These findings highlight not only the importance of low mental health and unfavourable working conditions but also the simultaneous impact of conflicts between work and family to employees' intentions to retire early.

To describe the patient's self assessed health related quality of life (saHRQoL) based upon the medical outcome study 36-item short form health survey (SF-36) as well as the factors of influence upon the saHRQoL following surgery for petroclival (PCM) and lateral posterior surface of the pyramid (LPPM) meningiomas. In a series of 78 patients operated consecutively for PCM (n = 46) or LPPM (n = 32) the preoperative, intraoperative and postoperative data were collected retrospectively. The saHRQoL was obtained by mailing the SF-36 questionnaire to the patients. The SF-36 data of the whole patients group was compared with a healthy population. The SF-36 data of the PCM- and LPPM were compared to each other. The influence of pre-, intra- and postoperative findings upon the SF-36 was assessed by uni- and multifactorial analysis. 58 (69%) out of the 78 patients answered the SF-36 questionnaire at a median postoperative follow-up of 59 months. The patients, who answered the SF-36 questionnaire, had a significant lower perioperative complication rate than those who did not (46% vs. 75%, p = 0.019). The saHRQoL of the LPPM and PCM was reduced on several sub-scales, when compared to the German reference population. The outcome of PCM is, assessed by saHRQoL as well as by conventional neurosurgical grading scales, inferior to that of LPPM. The saHRQoL of LPPM correlated in the uni- and multivariate analysis with the early postoperative KPI on the sub-scales SF1 (physical functioning) and SF5 (vitality). Accordingly, the sub-scale SF2 (role-physical) of PCM correlated with the change of the KPI from preoperative to the last follow up. The saHRQoL of the evaluable patients was lower than that of the normal population. The saHRQoL score of PCM-patients was lower than that of LPPM-patients. For the future the saHRQol should be assessed routinely; It reflects the patients' perspective upon postoperative outcome and enables the comparison with other treatment modalities

Self-reported health status measures, like the Short Form 36-item Health Survey (SF-36), can provide rich information about the overall health of a population and its components, such as physical, mental, and social health. However, differential item functioning (DIF), which arises when population sub-groups with the same underlying (i.e., latent) level of health have different measured item response probabilities, may compromise the comparability of these measures. The purpose of this study was to test for DIF on the SF-36 physical functioning (PF) and mental health (MH) sub-scale items in a Canadian population-based sample. Study data were from the prospective Canadian Multicentre Osteoporosis Study (CaMos), which collected baseline data in 1996-1997. DIF was tested using a multiple indicators multiple causes (MIMIC) method. Confirmatory factor analysis defined the latent variable measurement model for the item responses and latent variable regression with demographic and health status covariates (i.e., sex, age group, body weight, self-perceived general health) produced estimates of the magnitude of DIF effects. The CaMos cohort consisted of 9423 respondents; 69.4% were female and 51.7% were less than 65 years. Eight of 10 items on the PF sub-scale and four of five items on the MH sub-scale exhibited DIF. Large DIF effects were observed on PF sub-scale items about vigorous and moderate activities, lifting and carrying groceries, walking one block, and bathing or dressing. On the MH sub-scale items, all DIF effects were small or moderate in size. SF-36 PF and MH sub-scale scores were not comparable across population sub-groups defined by demographic and health status variables due to the effects of DIF, although the magnitude of this bias was not large for most items. We recommend testing and adjusting for DIF to ensure comparability of the SF-36 in population-based investigations.

OBJECTIVE: To determine the concurrent validity of the Brazilian version of the revised questionnaire of the Scoliosis Research Society (Br-SRS-22r and the Brazilian version of the Short-Form-36 questionnaire (SF-36. METHODS: Fifty-four patients with idiopathic scoliosis were selected. The mean age was 19.9 yrs. (±7.7 and the mean Cobb angle of curvature was 31.6° (±20.5°, ranging from 10º to 92º. The results from each questionnaire were converted into scores and, in the statistical analyses, the relationships between the concurrent domains were analyzed using Spearman's correlation coefficient. RESULTS: The best correlations were found between the function and pain domains: function in the Br-SRS-22r and physical function in the Br-SF-36 (r=0.83; pain in the Br-SRS-22r and pain in the Br-SF-36 (r=0.86. However, the domains of self-image and satisfaction with treatment with the Br-SRS-22r showed moderate and poor correlations with their corresponding domains in the Br-SF-36. There were moderate correlations between the questionnaires, with the best correlations showing greater similarity in the evaluated parameters between the respective instruments. Unlike the function and pain domains, the mental health domains did not have a good correlations, possibly because of difficulties in interpreting of the questions in the Br-SF-36. For the self-image and satisfaction domains, the correlations were moderate and poor because these topics were not specifically covered by the SF-36. CONCLUSIONS: The Brazilian version of the SRS-22r demonstrated moderate concurrent validity results in relation to the Br-SF-36, and this version adapted for the Brazilian culture was deemed valid.

Full Text Available Aim. Health state utilities measures are preference-weighted patient-reported outcome (PRO instruments that facilitate comparative effectiveness research. One such measure, the SF-6D, is generated from the Short Form 36 (SF-36. This report describes a psychometric evaluation of the SF-6D in a cross-sectional population of lower extremity sarcoma patients. Methods. Patients with lower extremity sarcoma from a prospective database who had completed the SF-36 and Toronto Extremity Salvage Score (TESS were eligible for inclusion. Computed SF-6D health states were given preference weights based on a prior valuation. The primary outcome was correlation between the SF-6D and TESS. Results. In 63 pairs of surveys in a lower extremity sarcoma population, the mean preference-weighted SF-6D score was 0.59 (95% CI 0.4–0.81. The distribution of SF-6D scores approximated a normal curve (skewness = 0.11. There was a positive correlation between the SF-6D and TESS (r=0.75, P<0.01. Respondents who reported walking aid use had lower SF-6D scores (0.53 versus 0.61, P=0.03. Five respondents underwent amputation, with lower SF-6D scores that approached significance (0.48 versus 0.6, P=0.06. Conclusions. The SF-6D health state utilities measure demonstrated convergent validity without evidence of ceiling or floor effects. The SF-6D is a health state utilities measure suitable for further research in sarcoma patients.

Background and objectives: The Short Form 12 (SF-12) has not been validated for long-term dialysis patients. The study compared physical and mental component summary (PCS/MCS) scores from the SF-36 with those from the embedded SF-12 in a national cohort of dialysis patients. Design, setting, participants, & measurements: All 44,395 patients who had scorable SF-36 and SF-12 from January 1, 2006, to December 31, 2006, and were treated at Fresenius Medical Care, North America facilities were included. Death and first hospitalization were followed for up to 1 year from the date of survey. Correlation and agreement were obtained between PCS-36 and PCS-12 and MCS-36 and MCS-12; then Cox models were constructed to compare associated hazard ratios (HRs) between them. Results: Physical and mental dimensions both exhibited excellent intraclass correlation coefficients of 0.94. Each incremental point for both PCS-12 and PCS-36 was associated with a 2.4% lower adjusted HR of death and 0.4% decline in HR for first hospitalization (both P < 0.0001). Corresponding improvement in HR of death for each MCS point was 1.2% for MCS-12 and 1.3% for MCS-36, whereas both had similar 0.6% lower HR for hospitalization per point (all P < 0.0001). Conclusions: The use of the SF-12 alone or as part of a larger survey is valid in dialysis patients. Composite scores from the SF-12 and SF-36 have similar prognostic association with death and hospitalization risk. Prospective longitudinal studies of SF-12 surveys that consider responsiveness to specific clinical, situational, and interventional changes are needed in this population. PMID:20019120

Full Text Available BACKGROUND: Appropriate instruments for the assessment of health-related quality of life (HRQOL domains are useful for planning therapeutic interventions for individuals with stroke. The generic quality of life (QOL instruments, Short Form Health Survey-36 (SF-36 and Nottingham Health Profile (NHP, have been frequently employed in the Brazilian literature. However, the literature is still scarce regarding their psychometric properties when applied to stroke individuals. OBJECTIVES: To compare the Brazilian versions of the SF-36 and the NHP to verify which had better psychometric properties for the assessment of HRQOL in 120 individuals with chronic stroke. METHOD: Spearman correlation coefficients were calculated to examine the comparable domains and total scores of the SF-36 and the NPH; Cronbach's alpha coefficients, to evaluate internal consistency; intra-class correlation coefficients, to assess reliability; and Bland-Altman plots, to assess the levels of agreement, with a significance level of 5%. RESULTS: Significant positive associations were observed between the common domains and the total scores of the SF-36 and the NPH. Ceiling effects were more frequent for the NPH. The total scores of both instruments achieved adequate reliability levels, and the agreement levels were within the normal limits in 95% of the cases. CONCLUSIONS: The SF-36 and the NPH were shown to measure similar constructs and proved to be useful measures for the assessment of QOL of chronic stroke subjects. However, the SF-36 yielded better results and appeared to be more appropriate.CONTEXTUALIZAÇÃO: Instrumentos adequados para avaliar os vários domínios da qualidade de vida (QV relacionada à saúde (QVRS constituem uma importante abordagem para o planejamento terapêutico e, assim, melhor assistir os indivíduos acometidos pelo acidente vascular encefálico (AVE.

Cystic fibrosis (CF) is a genetic disorder, which is most common among Caucasians. There are about 100,000 people suffering from this disorder in the world, including 25 000 in Europe. Although the first mention of cystic fibrosis is thought to have occurred in 1595, recognition of the entire clinical spectrum of CF and the resultant development of contemporary knowledge occurred in the 20th century. In the past, CF was considered a fatal childhood disorder; however, contemporary statistical data shows that 50% of people with cystic fibrosis have a chance to live up to 30 years of age, and the lifespan of children born in the 1990s is projected to be at least 40 years. Consequently, the number of adults with cystic fibrosis is increasing, making it necessary for multidisciplinary actions aimed at the improvement of clinical management of the condition as well as minimizing the influence of CF and its treatment on the quality of continually extending life of patients. Since cystic fibrosis interferes with almost all important aspects of human functioning, quality of life (QoL) of individuals with CF should be constantly and closely monitored, thus allowing for consideration of their needs and providing an opportunity to modify the therapeutic approach if necessary. The aim of this study was to visualize the QoL of people with cystic fibrosis, to identify differences in their assessment of QoL depending on sex and age, as well as to compare the QoL of patients with CF with a control group of people without CF. The study was conducted among patients hospitalized at the Clinic of Pulmonology and Cystic Fibrosis at the Institute of Tuberculosis and Lung Diseases in Rabka-Zdrój from February to April 2012. The study encompassed 30 patients (19 women and 11 men), aged between 16 and 42 years, with acute episodes of bronchopulmonary disease. A Short Form-36 (SF-36) questionnaire was used to evaluate the health-related quality of life. The control group encompassed 30

To evaluate quality of life (QoL) in women with postmenopausal osteoporosis, correlating the QUALEFFO 41 with the short-form health survey 36 (SF-36) and evaluated some factors that can influenced the QoL of women with osteoporosis. A cross-sectional study was conducted in 220 postmenopausal women (ages ranging from 55 to 80 years). Of the total number, 110 women had osteoporosis and 110 women did not have osteoporosis and these women were age-matched (+/-3 years). Two questionnaires were administered to all subjects for evaluation of QoL: the quality of life questionnaire of the European foundation for Osteoporosis 41 (QUALEFFO 41) and the short-form health survey 36 (SF-36). For data analysis, a significance level of 5% was set (posteoporosis had a worse QoL both in the QUALEFFO 41 and in the SF-36, in all domains studied. Data was adjusted for BMI, race, school education and use of HT (p25 and sedentary lifestyle. In contrast, paid work was associated with a better QoL (CI=95%). Women with osteoporosis had an impaired QoL, especially relating to the physical, psychological and social aspects. The factors associated with QoL were obesity, sedentary lifestyle and paid work.

Background Many national surveys have found substantial differences in self-reported overall health (SROH) between Spanish-speaking Hispanics and other racial/ethnic groups. However, because cultural and language differences may create measurement bias, it is unclear whether observed differences in SROH reflect true differences in health. Objectives This study uses a cross-sectional survey to investigate psychometric properties of the SF-36v2 for subjects across four racial/ethnic and language groups. Multi-group latent variable modeling was used to test increasingly stringent criteria for measurement equivalence. Subjects Our sample (N = 1281) included 383 non-Hispanic whites, 368 non-Hispanic blacks, 206 Hispanics interviewed in English and 324 Hispanics interviewed in Spanish recruited from outpatient medical clinics in two large urban areas. Results We found weak factorial invariance across the four groups. However, there was no strong factorial invariance. The overall fit of the model was substantially worse (change in CFI > .02, RMSEA change > .003) after requiring equal intercepts across all groups. Further comparisons established that the equality constraints on the intercepts for Spanish-speaking Hispanics were responsible for the decrement to model fit. Conclusions Observed differences between SF-36v2 scores for Spanish speaking Hispanics are systematically biased relative to the other three groups. The lack of strong invariance suggests the need for caution when comparing SF-36v2 mean scores of Spanish-speaking Hispanics with those of other groups. However, measurement equivalence testing for this study supports correlational or multivariate latent variable analyses of SF-36v2 responses across all four subgroups, since these analyses require only weak factorial invariance.

Chronic heart failure (CHF), a major public health problem worldwide, seriously limits health-related quality of life (HRQOL). How to evaluate HRQOL in older patients with CHF remains a problem. To evaluate the reliability and validity of the Chinese version of the Medical Outcomes Study Short Form version 2 (SF-36v2) in CHF patients. From September 2012 to June 2014, we assessed QOL using the SF-36v2 in 171 aging participants with CHF in four cardiology departments. Convergent and discriminant validity, factorial validity, sensitivity among different NYHA classes and between different age groups, and reliability were determined using standard measurement methods. A total of 150 participants completed a structured questionnaire including general information and the Chinese SF-36v2; 132 questionnaires were considered valid, while 21 patients refused to take part. 25 of the 50 participants invited to complete the 2-week test-retest questionnaires returned completed questionnaires. The internal consistency reliability (Cronbach's α) of the total SF-36v2 was 0.92 (range 0.74-0.93). All hypothesized item-subscale correlations showed satisfactory convergent and discriminant validity. Sensitivity was measured in different NYHA classes and age groups. Comparison of different NYHA classes showed statistical significance, but there was no significant difference between age groups. We confirmed the SF-36v2 as a valid instrument for evaluating HRQOL Chinese CHF patients. Both reliability and validity were strongly satisfactory, but there was divergence in understanding subscales such as "social functioning" because of differing cultural background. The reliability, validity, and sensitivity of SF-36v2 in aging patients with CHF were acceptable.

Normative data for the SF-36 measure of health-related quality of life (HRQOL) exist for those over 25 years of age, based on data from the population-based Canadian Multicentre Osteoporosis Study (CaMos). CaMos recently recruited a sample of young Canadians aged between 16 and 24 years. The purpose of this study was to develop normative SF-36 data for this age group. After direct standardization to the Canadian population, means, standard deviations (SD), 95% confidence intervals and percentage at floor and ceiling were produced for the eight domain and two summary scores of the SF-36. Domains are scored from 0 (poor) to 100 (excellent). Summary scores are standardized to a mean of 50, with scores over 50 representing better than average and below 50 poorer than average function. Separate analyses were completed for men and women, and for those 16-19 years and 20-24 years. The 1,001 community-based participants consisted of 474 men and 527 women from nine CaMos centres across Canada. Mean Physical Component Summary scores were 53.9 (SD = 6.9) and 53.3 (SD = 5.7) for young men and women, respectively. The equivalent Mental Component Summary scores were 49.3 (SD = 9.7) and 48.8 (SD = 8.9). In general, men scored somewhat higher than women, and younger (16-19 years) women scored higher than older (20-24 years) women, although the differences were small. HRQOL is good in this cohort of young Canadians. Both men and women scored somewhat better on physically than mentally oriented domains. In general, Canadian scores were similar to those of the US, while a comparable Swedish sample scored higher than both countries on most domains. Results underscore the importance of taking country, age and gender into consideration when using normative data.

Full Text Available OBJECTIVES: The objective of this study was to describe and measure the loss of health related quality of life (HRQoL associated with obesity using two generic instruments. The first of these, the SF-36, is the most widely used and validated HRQoL instrument worldwide. However, it does not provide utility weights and cannot be used to measure quality adjusted life years (QALYs, an increasingly common unit for comparing the effect of health states in economic evaluation studies. The second, the AQoL-8D, is a multi-attribute utility (MAU instrument which was developed to increase sensitivity of previous MAU instruments to psycho-social dimensions of a health state and to allow the calculation of QALYs. Since the two instruments differ, an important additional objective of the study was to determine the validity of the AQoL-8D as judged by the SF-36, and therefore the confidence which might be placed upon its use in the context of obesity.METHODS: Data were obtained from patients waiting for bariatric surgery who had completed both the SF-36 and AQoL-8D quality of life instruments and a general questionnaire including height, weight, demographic and socio-economic information. For comparative purposes, scores were standardized using results from a representative sample of the general population. The content validity of the AQoL-8D was assessed by comparing it with the dimension scores from the SF-36 and the summary component (physical and mental scores. Overall scores from the SF-36 and AQoL-8D instruments were regressed upon patient BMI and the results from the AQoL-8D used to estimate the effect of overweight and obesity upon utility and lost QALYs.RESULTS: The comparison of the instruments indicated that the AQoL-8D has good convergent, concurrent and content validity. Using both instruments, obesity was significantly associated with lower scores for 14 of their 16 dimensions. AQoL-8D, in particular, identified a significant decrease in

The SF-36 is widely used to assess health-related quality of life (HRQOL), but with few longitudinal studies in healthy populations, it is difficult to quantify its natural history. This is important because any measure of change following an intervention may be confounded by natural changes in HRQOL. This paper assesses mean changes in SF-36 scores over a 3-year period in men and women between the ages of 40 and 59 years at baseline. Subjects were randomly selected from nine Canadian cities. Mean SF-36 changes over a 3-year period (1996/1997-1999/2000) were calculated for each gender within 5-year age categories. Multiple imputation was used to correct for potential bias due to missing data. The baseline cohort included 1,974 women and 975 men between 40 and 59 years. Mean changes in HRQOL tended to be small. Women demonstrated small average declines in 22 of the 32 age and domain groupings (4 age groups, 8 SF-36 domains) while men showed declines in 14/32. Most participants stayed within 10 points of their original baseline score. Mean SF-36 scores change only slightly over three years in middle-aged Canadians, although there is much individual variation. It may be necessary to adjust for the natural evolution of SF-36 scores when interpreting results from longitudinal studies.

We re-present and re-examine the analysis from the famous RAND Health Insurance Experiment from the 1970s on the impact of consumer cost sharing in health insurance on medical spending. We begin by summarizing the experiment and its core findings in a manner that would be standard in the current age. We then examine potential threats to the validity of a causal interpretation of the experimental treatment effects stemming from different study participation and differential reporting of outcomes across treatment arms. Finally, we re-consider the famous RAND estimate that the elasticity of medical spending with respect to its out-of-pocket price is −0.2, emphasizing the challenges associated with summarizing the experimental treatment effects from non-linear health insurance contracts using a single price elasticity.

Full Text Available Abstract Background The SF-36 has been used in a number of previous studies that have investigated the health status of childhood cancer survivors, but it never has been evaluated regarding data quality, scaling assumptions, and reliability in this population. As health status among childhood cancer survivors is being increasingly investigated, it is important that the measurement instruments are reliable, validated and appropriate for use in this population. The aim of this paper was to determine whether the SF-36 questionnaire is a valid and reliable instrument in assessing self-perceived health status of adult survivors of childhood cancer. Methods We examined the SF-36 to see how it performed with respect to (1 data completeness, (2 distribution of the scale scores, (3 item-internal consistency, (4 item-discriminant validity, (5 internal consistency, and (6 scaling assumptions. For this investigation we used SF-36 data from a population-based study of 10,189 adult survivors of childhood cancer. Results Overall, missing values ranged per item from 0.5 to 2.9 percent. Ceiling effects were found to be highest in the role limitation-physical (76.7% and role limitation-emotional (76.5% scales. All correlations between items and their hypothesised scales exceeded the suggested standard of 0.40 for satisfactory item-consistency. Across all scales, the Cronbach's alpha coefficient of reliability was found to be higher than the suggested value of 0.70. Consistent across all cancer groups, the physical health related scale scores correlated strongly with the Physical Component Summary (PCS scale scores and weakly with the Mental Component Summary (MCS scale scores. Also, the mental health and role limitation-emotional scales correlated strongly with the MCS scale score and weakly with the PCS scale score. Moderate to strong correlations with both summary scores were found for the general health perception, energy/vitality, and social functioning

Full Text Available CONTEXT AND OBJECTIVE Patients with beta-thalassemia major (β-TM experience physical, psychological and social problems that lead to decreased quality of life (QoL. The aim here was to measure health-related QoL and its determinants among patients with β-TM, using the Short Form-36 (SF-36 questionnaire. DESIGN AND SETTING Cross-sectional study at the Hematology Research Center of Shiraz University of Medical Sciences, in southern Iran. METHODS One hundred and one patients with β-TM were randomly selected. After the participants' demographics and disease characteristics had been recorded, they were asked to fill out the SF-36 questionnaire. The correlations of clinical and demographic factors with the QoL score were evaluated. RESULTS There were 44 men and 57 women of mean age 19.52 ± 4.3 years (range 12-38. On two scales, pain (P = 0.041 and emotional role (P = 0.009, the women showed significantly lower scores than the men. Lower income, poor compliance with iron-chelating therapy and presence of comorbidities were significantly correlated with lower SF-36 scores. These factors were also found to be determinants of worse SF-36 scores in multivariate analysis. CONCLUSIONS We showed that the presence of disease complications, poor compliance with iron-chelating therapy and poor economic status were predictors of worse QoL among patients with β-TM. Prevention and proper management of disease-related complications, increased knowledge among patients regarding the importance of managing comorbidities and greater compliance with iron-chelating therapy, along with psychosocial and financial support, could help these patients to cope better with this chronic disease state.

The Oswestry Disability Index v2.0 (ODI), SF36 Physical Function Domain (SF-36 PFD), and PROMIS Physical Function CAT v1.2 (PF CAT) questionnaires were prospectively collected from 1607 patients complaining of back or leg pain, visiting a university-based spine clinic. All questionnaires were collected electronically, using a tablet computer. The aim of this study was to compare the psychometric properties of the PROMIS PF CAT with the ODI and SF36 Physical Function Domain in the same patient population. Evidence-based decision-making is improved by using high-quality patient-reported outcomes measures. Prior studies have revealed the shortcomings of the ODI and SF36, commonly used in spine patients. The PROMIS Network has developed measures with excellent psychometric properties. The Physical Function domain, delivered by Computerized Adaptive Testing (PF CAT), performs well in the spine patient population, though to-date direct comparisons with common measures have not been performed. Standard Rasch analysis was performed to directly compare the psychometrics of the PF CAT, ODI, and SF36 PFD. Spearman correlations were computed to examine the correlations of the three instruments. Time required for administration was also recorded. One thousand six hundred seven patients were administered all assessments. The time required to answer all items in the PF CAT, ODI, and SF-36 PFD was 44, 169, and 99 seconds. The ceiling and floor effects were excellent for the PF CAT (0.81%, 3.86%), while the ceiling effects were marginal and floor effects quite poor for the ODI (6.91% and 44.24%) and SF-36 PFD (5.97% and 23.65%). All instruments significantly correlated with each other. The PROMIS PF CAT outperforms the ODI and SF-36 PFD in the spine patient population and is highly correlated. It has better coverage, while taking less time to administer with fewer questions to answer. 2.

Japanese patients with SLE ( n = 233) completed the SF-36 and other related demographic questionnaires, and physicians simultaneously completed the SLE Disease Activity Index 2000 (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics Damage Index (SDI). Patients were prospectively followed for a repeat assessment the following year. The SF-36 subscales demonstrated acceptable internal consistency (Cronbach's α of 0.85-0.89), and an overall good test-retest reliability (intraclass correlation coefficient >0.70). The average baseline SF-36 subscale/summary scores except for "bodily pain" were significantly lower than those of the Japanese general population ( p 36 subscale/summary scores except for "vitality" and "mental component summary" at baseline, whereas the SLEDAI-2K did not. In the second year, "social functioning" and "mental component summary" of the SF-36 deteriorated among patients whose SDI or SLEDAI-2K score increased (effect sizes 36 demonstrated acceptable reliability among Japanese patients with SLE. Health-related quality of life measured by the SF-36 was reduced in Japanese patients with SLE and associated with disease damage, rather than disease activity.

The Short-Form Health Survey (SF-36) is a valid quality of life tool often employed to determine the impact of medical intervention and the outcome of health care services. However, the SF-36 is culturally sensitive which necessitates its adaptation and translation into different languages. This study was conducted to cross-culturally adapt the SF-36 into Yoruba language and determine its reliability and validity. Based on the International Quality of Life Assessment project guidelines, a sequence of translation, test of item-scale correlation, and validation was implemented for the translation of the Yoruba version of the SF-36. Following pilot testing, the English and the Yoruba versions of the SF-36 were administered to a random sample of 1087 apparently healthy individuals to test validity and 249 respondents completed the Yoruba SF-36 again after two weeks to test reliability. Data was analyzed using Pearson's product moment correlation analysis, independent t-test, one-way analysis of variance, multi trait scaling analysis and Intra-Class Correlation (ICC) at p Yoruba SF-36 ranges between 0.636 and 0.843 for scales; and 0.783 and 0.851 for domains. The data quality, concurrent and discriminant validity, reliability and internal consistency of the Yoruba version of the SF-36 are adequate and it is recommended for measuring health-related quality of life among Yoruba population.

Heart failure is one of the major chronic diseases that affect health related quality of life. The objective of this study was to evaluate the quality of life in patients with New York Heart Association functional class I-III using the SF-36 on a cohort of survivors of the EPICOUR Study Group and compare the quality of life with the general Spanish population of the same sex and age group. A cohort study, observational, and prospective study was conducted on survivors of the EPICOUR Study Group, on whom a clinical-progression-outcome review was performed along with the SF-36. The quality of life was studied in 50 patients (60% male). The average age of men was 64.8 years and women 68.3. When analyzing the SF-36, it was observed that the results were lower in the physical dimensions than in the mental dimensions. The quality of life worsened with increasing functional class (statistically significant differences for scales of physical functioning, social functioning and borderline significance in mental health scale). When comparing patients with the general population of the same age and sex, patients with heart failure showed lower scores on all scales (significant differences in physical functioning, body pain, vitality, and social role for men, and physical function and emotional role for women). Heart failure causes a negative impact on quality of life, physical functioning, as well as psychosocial function, with the impairment becoming worse with increased functional class.

This study aimed to describe the Health-related quality of life (HRQoL) outcomes for Korean chronic hepatitis C patients and to investigate the impact of patient and virus-related factors on HRQoL. HRQoL was assessed in 235 HCV-infected patients from 7 nationwide tertiary hospital, including those with liver cirrhosis and hepatocellular carcinoma (HCC), using the Shor-Form 36 (SF-36) version 2 and the European quality of life questionnaire-5 dimensions (EQ-5D-3L). The SF-36 physical (48.8±8.3) and mental (46.2±11.7) component summary scores of the HCV-infected patients were below normal limits. Of the eight domains, general health, vitality, and mental health tended to show low scores. Patients with decompensated cirrhosis had the lowest HRQoL, while HCC and chronic hepatitis patients had similar HRQoL results. The EQ-5D index was low (0.848±0.145) in the HCV infected patients. Multivariable analysis showed age ≤65 years, high monthly family income (>$2,641), low comorbidity score, and sustained virologic response (SVR) were independently associated with favorable HRQoL. HRQoL in Korean patients with chronic HCV infection was low and was affected by cirrhosis severity, SVR, and comorbidity as well as income, which had the strongest effect. Therefore, HRQoL may be improved by antiviral therapy with reasonable costs to prevent cirrhosis progression.

To identify the factors that affect SF-36 mental component summary (MCS) in patients with adult spinal deformity (ASD) at the time of presentation, and to analyse the effect of SF-36 MCS on clinical outcomes in surgically treated patients. Prospectively collected data from a multicentric ASD database was analysed for baseline parameters. Then, the same database for surgically treated patients with a minimum of 1-year follow-up was analysed to see the effect of baseline SF-36 MCS on treatment results. A clinically useful SF-36 MCS was determined by ROC Curve analysis. A total of 229 patients with the baseline parameters were analysed. A strong correlation between SF-36 MCS and SRS-22, ODI, gender, and diagnosis were found (p baseline SF-36 MCS (p baseline SF-36 MCS in an ASD population are other HRQOL parameters such as SRS-22 and ODI as well as the baseline thoracic kyphosis and gender.

Salivary cortisol was measured at three times during 1 workday: at awakening, 30min after awakening, and in the evening....... The results showed that diurnal cortisol variation was significantly reduced in exhausted individuals. The difference in cortisol variation was mainly due to lowered morning cortisol in the exhausted group. Differences in cortisol levels at each sampling time or in mean diurnal output of cortisol were...... not statistically significant. The results would support the notion that exhaustion is associated with HPA axis hypoactivity as assessed by salivary cortisol. Furthermore, the SF-36 vitality provides a measure of exhaustion that may be useful in epidemiological studies in order to explore long-term health effects...

Full Text Available Background: Quality of life is a multidimensional concept that includes physical, emotional and social components associated with the disease. The use of tools to assess the Quality of Life Health Related (HRQOL has increased in recent decades. Common variable immunode ciency (CVID is the most commonly diagnosed primary immunode ciency. Objective: To evaluate the quality of life in patients with CVID using the questionnaire SF -36. Patients and method: A descriptive cross-sectional survey included 23 patients diagnosed with CVID, belonging to the Immunode ciency Clinic Service of Allergology and Clinical Immunology in CMN Siglo XXI, IMSS. The questionnaire SF- 36 validated in Spanish was applied. Statistical analysis: descriptive statistics with simple frequencies and percentages, inferential statistics: Fisher exact test and ANOVA to compare means. Results: The study involved 23 patients, 14 women (60% and 9 men (40%, mean age 38.6 ± 14.7 years. The highest score was obtained in 83% emotional role. Dimensions with further deterioration in both gen- ders were: 54% general health, vitality 59% and physical performance 72%. No differences were found regarding gender. The only issue in which statistically signi cant differences were found in patients with more than 3 comorbidities was change in health status in the past year (p=0.007. Patients with severe comorbidities, such as haematological-oncological (leukemias, lymphomas, neoplasms, and pulmonary (severe bronchiectasis showed further deterioration in the aspects of physical performance 73% and 64% emotional role. 65% of patients reported an improvement in health status in 74% in the last year. Conclusions: Adult patients with CVID show deterioration in different dimensions, particularly in the areas of general health, vitality and physi- cal performance. Patients with severe comorbidities such as leukemia, lymphomas, malignancies and severe bronchiectasis show further deterioration in some

Research on determinants and correlates of HRQoL has, therefore, grown in importance. Earlier studies have generally been patient-based and few of them have examined differences between women and men. The aim of this study was to explore the relationship between psychological factors and physical, social, and mental dimensions of HRQoL, as measured by the Medical Outcome Study Short Form-36 Health Survey (SF-36, in a normal population and to see if observed relations were the same for women and men.Methods: Relations between scale scores for the eight scales of SF-36 and scale scores for Self-esteem, Sense of Coherence, Perceived Control, Depressed Mood (CES-D, and Cynicism were assessed through partial correlation and multiple linear regression analyses on a sample of 505 women and 502 men (aged 45–69 years, stratified for sex and adjusted for effects of age, presence of disease, back pain, lifestyle, and social support.Results: All psychological factors tested, except Cynicism, were significantly correlated to all scales of the SF-36 for women and men (Pearson product-moment partial correlation coefficient, |r| = 0.11–0.63 and |r| = 0.11–0.60, respectively. The addition of psychological factors into regression models resulted in significant total explained variance (R2 changes in all scales of the SF-36 for both sexes. Any discrepancies between women and men pertained more to the strength of relationships rather than the significance of different psychological factors.Conclusion: In this population-based study

Full Text Available OBJECTIVE : To compare the reliability and convergent validity of instruments assessing quality of life in Brazilian older adults. METHODS : Cross-sectional study of 278 literate, community-dwelling older adults attending a municipal university for the elderly in Sao Carlos, SP, Southeastern Brazil between 2006 and 2008. The Brazilian versions of the SF-36 and WHOQOL-BREF instruments to assess quality of life were compared. Cronbach’s alpha coefficient was used to estimate reliability and Pearson’s correlation for comparison between the two scales. RESULTS : Most of participants were women (87.8% with a mean age of 63.83±7.22 years. Both scales showed an acceptable internal consistency – WHOQOL-BREF Cronbach’s alpha was 0.832 and SF-36 was 0.868. There was a weak (r ≤ 0.6 correlation between the related fields in the two questionnaires. CONCLUSIONS : The SF-36 and WHOQOL-BREF are reliable instruments for clinical and research uses in Brazilian older women. To select one, researchers should consider which aspects of quality of life they aim to capture because of weak convergent validity signs. This study’s results indicate that WHOQOL-BREF may be more relevant to evaluate changes in the quality of life of older women because it prioritizes responses to the aging process and avoids focusing on impairment.

Cross-sectional study. To determine the correlation between SF-36 (a measure for overall health status in patients) and Oswestry-Disability Index (ODI) or Rolland-Morris Disability Questionnaire (RMDQ) confined to spine according to the type of pain from the spine. Data showed moderate correlation between ODI and SF-36 Physical Component Score (PCS), Physical Functioning (PF) (r=-0.46), Physical Role Functioning (RP) (r=-0.284), Bodily Pain (BP) (r=-0.327), and Mental Component Score (MCS), Emotional Role Functioning (r=-0.250), Social Role Functioning (r=0.254), Vitality (r=0.296). Between January 1, 2008 and December 31, 2013, a total of 69 patients were enrolled in this study. They were diagnosed with lumbar spinal stenosis and underwent decompression surgery such as laminotomy in this hospital. The 3 standardized questionnaires (ODI, RMDQ, and SF-36) were given to these patients, at least 1 year after the surgery. ODI and SF-36 had a statistically significant (P=0.001) and moderate correlation. Small correlations were also seen between Physical Functioning (r=-0.46), Physical Role Functioning (r=-0.284), and Bodily Pain (r=-0.327) of SF-36 PCS and ODI, and between Emotional Role Functioning (r=-0.250), Social Role Functioning (r=-0.254), and Vitality (r=-0.296) of SF-36 Mental Component Score and ODI. Items in ODI for the level of pain while standing and traveling were mostly related to axial back pain, while item of lifting was related to referred buttock pain. Sleeping disturbance section in the ODI was mainly caused by radiated leg pain. In addition, RMDQ was also associated to the 3 types of pain. Moderate correlation was found between ODI or RMDQ as a condition-specific outcome and the SF-36, indicating overall health status. ODI was found to be a more adequate measure to evaluate axial back pain rather than referred pain or radiating pain. RMDQ was adequate to measure the health status and to evaluate the 3 types of spine pain. These 3 instruments could

The use of bootstrap methods for analysing health-related quality of life outcomes (particularly the SF-36

Full Text Available Abstract Health-Related Quality of Life (HRQoL measures are becoming increasingly used in clinical trials as primary outcome measures. Investigators are now asking statisticians for advice on how to analyse studies that have used HRQoL outcomes. HRQoL outcomes, like the SF-36, are usually measured on an ordinal scale. However, most investigators assume that there exists an underlying continuous latent variable that measures HRQoL, and that the actual measured outcomes (the ordered categories, reflect contiguous intervals along this continuum. The ordinal scaling of HRQoL measures means they tend to generate data that have discrete, bounded and skewed distributions. Thus, standard methods of analysis such as the t-test and linear regression that assume Normality and constant variance may not be appropriate. For this reason, conventional statistical advice would suggest that non-parametric methods be used to analyse HRQoL data. The bootstrap is one such computer intensive non-parametric method for analysing data. We used the bootstrap for hypothesis testing and the estimation of standard errors and confidence intervals for parameters, in four datasets (which illustrate the different aspects of study design. We then compared and contrasted the bootstrap with standard methods of analysing HRQoL outcomes. The standard methods included t-tests, linear regression, summary measures and General Linear Models. Overall, in the datasets we studied, using the SF-36 outcome, bootstrap methods produce results similar to conventional statistical methods. This is likely because the t-test and linear regression are robust to the violations of assumptions that HRQoL data are likely to cause (i.e. non-Normality. While particular to our datasets, these findings are likely to generalise to other HRQoL outcomes, which have discrete, bounded and skewed distributions. Future research with other HRQoL outcome measures, interventions and populations, is required to

The health-related quality of life is an important element for the comprehensive assessment of overweight and obesity. To assess the impact of obesity and weight gain on the health-related quality of life of the dynamic cohort of the Follow-up Program of the University of Navarra. The analysis included 10,033 participants of the prospective dynamic cohort of the Follow-up Project of the University of Navarra, with a response rate of approximately 90%. The quality of life was measured with the Short Form 36 Health Survey (SF-36) (0, worst quality of life; 100, best quality of life). The statistical analysis was performed with generalized lineal models (mean of each SF-36 domain and 95% CI). A difference of 3 points was considered clinically relevant. The SF-36 analysis showed that physical function, general health and the physical component summary were inferior in individuals with excess weight and obesity at the start of the study, compared with individuals with normal weight. The study population with unchanged excess weight or obesity after 2 years of follow-up presented lower scores on the SF-36 domains corresponding to physical function, body pain, physical component summary and general health than individuals who maintained the normal weight category according to BMI (kg/m 2 ). Obesity appears to be associated with a negative impact on health-related quality of life, affecting the physical area more significantly than the psychosocial.

In addition, correlations between the SF-12 scales and single items showed that the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12 score, while the vitality, social functioning, role emotional and mental health subscales more correlated with the MCS-12 score lending support to its good convergent validity. Finally the principal component analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 57.8% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). In general the findings suggest that the SF-12 is a reliable and valid measure of health related quality of life among Iranian population. However, further studies are needed to

2014-09-01

The 12-item short-form health survey (SF-12) was developed as a shorter alternative to the SF-36 for use in large-scale studies as an applicable instrument for measuring health-related quality of life. The main purpose of this study was to evaluate the psychometric properties of the Tunisian version of the SF-12. A stratified representative sample (N = 3,582) of the general Tunisian population aged 18 years and over was interviewed. SF-12 summary scores were derived using the standard US algorithm. Factor analysis was used to confirm the hypothesized component structure of the SF-12 items. Reliability was estimated using internal consistency, and construct validity was investigated with "known groups" validity testing and via convergent and divergent validity. SF-12 summary scores distinguished well, and in the expected manner, between groups of respondents on the basis of gender, age, education and socioeconomic status, thus providing evidence of construct validity. Mean scores in the total sample were 50.11 (SD 8.53) for the physical component summary (PCS) score and 47.96 (SD 9.82) for the mental component summary (MCS) score. The results showed satisfactory internal consistency and acceptable convergent validity for both summary scores. Cronbach's α coefficient for PCS-12 and MCS-12 was 0.73 and 0.72, respectively. Known groups comparison showed that the SF-12 discriminated well between groups of respondents on the basis of gender, age, education and socioeconomic status. In addition, no floor or ceiling effects at baseline were observed. The PCA confirmed the two-factor structure of the SF-12 items. Items belonging to the physical component correlated more strongly with the PCS-12 than those with the MCS-12. Similarly, items belonging to the mental component correlated more strongly with the MCS-12 than those with the PCS-12. The findings suggest that the SF-12 appears to be a valid and reliable measure that can be used for measuring of population health

Long working hours and short sleep duration are associated with a range of adverse health consequences. However, the combined effect of these two exposures on health-related quality of life (HRQoL) has not been investigated. We studied white men born between 1919 and 1934 in the Helsinki Businessmen Study (HBS, initial n = 3,490). Data on clinical variables, self-rated health (SRH), working hours and sleep duration in 1974, and RAND-36 (SF-36) HRQoL survey in the year 2000 were available for 1,527 men. Follow-up time was 26 years. By combining working hours and sleep duration, four categories were formed: (i) normal work (≤50 hours/week) and normal sleep (>47 hours/week); (ii) long work (>50 hours/week) and normal sleep; (iii) normal work and short sleep (≤47 hours/week); and (iv) long work and short sleep. The association with RAND-36 domains was examined using multiple linear regression models adjusted for age, smoking and SRH. Compared to those with normal work and sleep in midlife, men with long work and short sleep had poorer RAND-36 scores for physical functioning, vitality and general health, and those with long work and normal sleep had poorer scores for physical functioning in old age. Adjustment for midlife smoking and SRH attenuated the associations, but the one for long work and short sleep and physical functioning remained significant (difference in mean physical functioning score −4.58, 95% confidence interval −9.00 to −0.15). Businessmen who had long working hours coupled with short sleep duration in midlife had poorer physical health in old age. © The Author 2016.

A comparison study of Back Pain Functional Scale (BPFS) with Roland Morris Questionnaire (RMQ), Oswestry Disability Index (ODI) and Short Form 36-Health Survey (SF-36). The aim of this study is to investigate the correlation of BPFS with RMQ, ODI and SF-36. The primary goal in the treatment of patients with low back pain is to improve the patients' levels of activities and participation. Many questionnaires focusing on function have been developed in patients with low back pain. BPFS is one of these questionnaires. No studies have investigated the correlation of BPFS with ODI and SF-36. This study was conducted with 120 patients receiving outpatient and inpatient treatment in physiotherapy and rehabilitation units of a state hospital. BPFS, RMQ, ODI, SF-36 questionnaires were used to assess the disability in low back pain. Spearman and Pearson Correlation were used to compare the data obtained in the study. There was a good correlation among the five functional outcome measures (correlation r = -0.693 for BPFS/RMQ, r = -0.794 for BPFS/ODI, r = 0.697 for BPFS/SF-36 Physical function and r = 0.540 for BPFS/SF-36 Pain). BPFS demonstrated good correlation with RMQ, ODI, SF-36 physical function and SF-36 pain. 2.

Establecer, con la Encuesta SF-36, un perfil multidimensional del estado de salud de una población del sureste de México y analizar las propiedades psicométricas de una traducción de la Encuesta SF-36 autorizada por el Proyecto Internacional de Evaluación de la Calidad de Vida. Material y métodos. La SF-36 se aplicó a 257 participantes voluntarios de una clínica médica y a un grupo control de una institución pública gubernamental. Se utilizó, sin modificar, la metodología de construcción de las escalas de salud propuestas por los autores de la encuesta. Se analizó psicométricamente la validez y la confiabilidad de la adaptación de la SF-36 para su uso en México. Resultados. Se construyeron ocho escalas o conceptos de salud relacionados con función física, rol físico, dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental. En los participantes de los servicios médicos la escala con más bajo promedio fue la de salud general (63, y la más alta, la de rol físico (89. En la población control la escala con promedio más alto fue función física (94.6, y la más baja, salud general (73. La comparación de promedios de escalas en ambos grupos de participantes mostró diferencias estadísticamente significativas en función física, rol físico, dolor corporal, salud general y vitalidad. Conclusiones. Con base en los resultados de la evaluación psicométrica, la SF-36 muestra que es consistente con todos los supuestos de validez y confiabilidad en forma satisfactoria, aunque la traducción de ciertas preguntas se examinará en profundidad para determinar modificaciones subsecuentes.

To compare the sensitivity to change and the responsiveness to intervention of the PROMIS Pain Interference short forms, Brief Pain Inventory (BPI), 3-item PEG scale, and SF-36 Bodily Pain subscale in a sample of patients with persistent musculoskeletal pain of moderate severity. Standardized response means, standardized effect sizes, and receiver operating curve analyses were used to assess change between baseline and 3-month assessments in 250 participants who participated in a randomized clinical effectiveness trial of collaborative telecare management for moderate to severe and persistent musculoskeletal pain. The BPI, PEG, and SF-36 Bodily Pain measures were more sensitive to patient-reported global change than the PROMIS Pain Interference short forms, especially for the clinically improved group, for which the change detected by the PROMIS short forms was not statistically significant. The BPI was more responsive to the clinical intervention than the SF-36 Bodily Pain and PROMIS Pain Interference measures. Post hoc analyses exploring these findings did not suggest that differences in content or rating scale structure (number of response options or anchoring language) adequately explained the observed differences in the detection of change. In this clinical trial, the BPI and PEG measures were better able to detect change than the SF-36 Bodily Pain and PROMIS Pain Interference measures.

Are there meaningful longitudinal changes in health related quality of life--SF36, in cardiac rehabilitation patients?

BACKGROUND: This study aimed to observe changes in quality of life and minimal clinical important differences of quality of life over time in cardiac rehabilitation patients and to compare these with published normal data. METHODS: In this non-randomised study, SF36 questionnaires were completed by 187 patients recruited to a Phase III cardiac rehabilitation multidisciplinary outpatient programme. Data was collected at beginning, end and six months after Phase III cardiac rehabilitation programme. RESULTS: There were significant improvements in physical functioning, role limitation due to physical function, pain and general health perception scales, over the above time frame, from both a statistically and a mean clinical important difference point of view. These improvements occurred mainly during the cardiac rehabilitation programme phase. CONCLUSIONS: These improvements meant that patients six months post-cardiac rehabilitation were only 5% below the quality of life for an aged matched normal group. However patients still had significant deficits in physical role and emotional role limitations. Suitable measurement of quality of life on an individual basis, supported by normal values is needed. This would facilitate the identification of shortfalls in patient quality of life and the subsequent tailoring of care to address these individualised patient needs.

Anterior cruciate ligament (ACL) tears are associated with the development of knee osteoarthritis despite ACL reconstruction surgery. However, little evidence is available to determine which patients will develop symptomatic knee osteoarthritis. To determine if preoperative outcome measures-KOOS (Knee injury and Osteoarthritis Outcome Score) and SF-36 (36-item Short Form Health Survey)-were associated with the development of a symptomatic knee 7 years after ACL reconstruction. A secondary goal was to examine the relationship between imaging evidence of knee osteoarthritis and development of knee pain. Case-control study; Level of evidence, 3. Prospectively collected data from 72 patients were reviewed with 7-year follow-up after unilateral ACL reconstruction. Patients were divided into symptomatic and asymptomatic groups based on the previously defined KOOS pain ≤72. Demographic variables and preoperative KOOS and SF-36 scores were compared between groups. Radiographic and magnetic resonance imaging data were used to evaluate differences in joint space width, Osteoarthritis Research Society International radiographic score, and the Whole-Organ Magnetic Resonance Imaging Score between groups. Univariate and multivariate analyses were performed to identify potential predictors of pain at 7-year follow-up. Wilcoxon sum rank and t tests were used to compare imaging findings between the symptomatic and asymptomatic patients at 7 years. According to KOOS pain, 7 of the 72 patients available at 7-year follow-up formed the symptomatic group. No differences were found between groups in regard to demographic variables or intraoperative findings. In multivariate analysis, lower preoperative scores for KOOS sports/recreation ( P = .005) and SF-36 mental health ( P = .025) were associated with a painful knee at 7 years, with increased odds of 82% and 68% per 10-unit decrease, respectively. The Whole-Organ Magnetic Resonance Imaging Score at 7 years showed evidence of

To examine criterion and construct validity of the five-item Mental Health Index (MHI-5) of the 36-item Short Form health survey (SF-36) in relation to the presence of major depression in functionally impaired, community-dwelling elderly patients and of eight subsamples defined by cognitive functioning, levels of functional impairment, and proxy report versus self-report. Cross-sectional observational. Nineteen counties in western New York, West Virginia, and Ohio. One thousand four hundred forty-four functionally impaired, community-dwelling Medicare beneficiaries aged 65 and older who participated in the Medicare Primary and Consumer-Directed Care Demonstration. MHI-5, Mini-International Neuropsychiatric Interview Major Depressive Episode (MINI-MDE) module. The MHI-5 demonstrated sufficient criterion validity (area under the receiver operating characteristic curve=0.837; sensitivity=78.7% and specificity=72.1% using a cutpoint of 59/60) with respect to the presence of depression for the entire sample. A significant correlation between MHI-5 scores and presence of major depression as identified using the MINI-MDE (Spearman correlation=-0.426, Pvalidity. Additional evidence is provided by decline in mean MHI-5 score as level of formal education and number of close friends and relatives decreased. All eight subsamples demonstrated similar criterion and construct validity. A Cronbach alpha of 0.794 demonstrated internal consistency reliability. This study provides evidence for adequate criterion and construct validity of the MHI-5 in relation to the presence of major depression among functionally impaired, community-dwelling elderly Medicare patients.

The 12-item Short-Form Health Survey (SF-12) is the abridged practical version of SF-36. This cross-sectional study was aimed to assess the reliability and validity of SF-12 for the health status of Chinese community elderly population. The Chinese community elderly people in Xujiahui district of Shanghai were investigated. The internal consistency reliability was assessed using Cronbach's alpha and split-half reliability coefficients. Construct validity was analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Spearman's correlation coefficient (ρ) was used for the evaluation of criterion, convergent, and discriminant validity with Spearman's ρ ≥ 0.4 as satisfactory. Comparisons of the SF-12 summary scores among populations that differed in demographics were performed for discriminant validity. Total 1343 individuals aged ≥60 and reliability coefficient (0.812) reflected satisfactory internal consistency reliability of SF-12. EFA extracted a two-factor model (physical and mental health). About 60.7 % of the total variance was explained by the two factors. CFA showed that the two-factor solution provided a good fit to the data. Good convergent validity and discriminant validity of SF-12 were proved by the correction analyses (Spearman's ρ > 0.4) and the comparisons of the SF-12 summary scores among populations (P  0.4, P reliability and validity in measuring health status of Chinese community elderly population in Xujiahui district of Shanghai.

Even though 85 percent of those who have been severely injured in an accident in Germany survive, complex and serious long-term consequences are still a major problem not only for health and care insurance providers but also for the accident victims themselves because their quality of life is affected permanently. Therefore the aim of the current study is to identify factors that significantly improve the quality of life after a severe traumatic injury and to investigate whether the support by a reintegration service has a positive effect on the victims' quality of life. The sample consisted of severely injured accident victims who were supported by a reintegration service. The data collection comprised three data points. At every data point the SF-36 questionnaire was used to assess the participants' quality of life. The results indicate that an individual medical-vocational support by a reintegration service has the potential to significantly and stably improve the physical aspects of quality of life, even if the accident dates back several years. Furthermore it appears to be important to support the independence of the accident victims because assistance by a third person correlates with a lower degree of physical quality of life, regardless of severity or type of injury. Moreover it becomes clear that it is important to pay more attention to the treatment of psychological consequences of severe accidents.

Nichols, Thom R

The purpose of this study was to assess the Mental Health Component of health-related quality of life (HRQOL) in community-dwelling persons with ostomies residing in the United States. Cross-sectional descriptive study. Two thousand three hundred twenty-nine participants completed the survey for a response rate of 14.9% and a margin of error of 2.03%. Study respondents were geographically distributed throughout the United States, representing all 50 states. Fifty-three percent of study respondents were male. Respondents had a median age of 65 years. Forty percent have colostomies, 44% are living with ileostomies, and 13% have urostomies. The remaining 3% are living with multiple stomas or they indicated that they were uncertain as to the type of stoma. The SF36v2 was used to assess HRQOL. This instrument was selected because it has the ability to measure HRQOL in a target population and it allows comparison with the general population. Potential participants were randomly selected from an electronic database of 15,591 persons with ostomies. They were contacted by e-mails and provided with an electronic nontransferable link to the survey. This is a secondary analysis of findings from the Mental Component Summary (MCS) of the SF36v2. Persons who have undergone ostomy surgery did not score as well as the general population when components of the MCS were compared. While overall differences were identified, they differed based on age and cumulative MCS score levels. Analysis of individuals found to have significant impairment in MCS scores (cumulative soccer ostomies as lower than scores generated from the general population. However, these findings varied based on age and cumulative MCS score.

Health utility values permit cost utility analysis in workplace health promotion; however, utility measures of working populations have not been validated. To investigate construct validity of SF-6D health utility in a public service workforce. SF-12v2 Health Survey was administered to 3,408 randomly selected public service employees in Australia in 2010. SF-12 scores were converted to SF-6D health utility values. Associations and correlates of SF-6D with health, socio-demographic and work characteristics [comorbidities, body mass index (BMI), Kessler-10 psychological distress (K10), education, salary, effort-reward imbalance (ERI), absenteeism] were explored. Ceiling effects were analysed. Nationally representative employee SF-6D values from the Household, Income and Labour Dynamics in Australia (HILDA) survey (n = 11,234) were compared. All analyses were stratified by sex. Mean (SE) age was 45.7 (0.35) males; 44.5 (0.22) females. Females represented 72 % of the sample. Mean (SE) health utility 0.792 (0.004); 0.771 (0.003) was higher in males. SF-6D demonstrated both a significant inverse association (p negative correlations (female; male) with K10 (r = -0.63; r = -0.66), comorbidity count (r = -0.40; r = -0.33), ERI (r = -0.37; r = -0.34) and absenteeism (p imbalance and absenteeism are negatively associated with employee health. SF-6D is a valid measure of perceived health states in working populations.

When health state utility values for comorbid health conditions are not available, data from cohorts with single conditions are used to estimate scores. The methods used can produce very different results and there is currently no consensus on which is the most appropriate approach. The objective of the current study was to compare the accuracy of five different methods within the same dataset. Data collected during five Welsh Health Surveys were subgrouped by health status. Mean short-form 6 dimension (SF-6D) scores for cohorts with a specific health condition were used to estimate mean SF-6D scores for cohorts with comorbid conditions using the additive, multiplicative, and minimum methods, the adjusted decrement estimator (ADE), and a linear regression model. The mean SF-6D for subgroups with comorbid health conditions ranged from 0.4648 to 0.6068. The linear model produced the most accurate scores for the comorbid health conditions with 88% of values accurate to within the minimum important difference for the SF-6D. The additive and minimum methods underestimated or overestimated the actual SF-6D scores respectively. The multiplicative and ADE methods both underestimated the majority of scores. However, both methods performed better when estimating scores smaller than 0.50. Although the range in actual health state utility values (HSUVs) was relatively small, our data covered the lower end of the index and the majority of previous research has involved actual HSUVs at the upper end of possible ranges. Although the linear model gave the most accurate results in our data, additional research is required to validate our findings.

The aim of the study was to perform an analysis of the emotional reactions, perception of stressful life and behavioural changes related to Haemodialysis (HD) in order to identify those variables that can improve lifestyle and the adherence to treatment. Some psychometric assessment, such as the Cognitive Behavioural Assessment, Hospital Form, (CBA-H) and the Health Survey (SF-36), which provides two indexes: the Physical Component Score (PCS) and the Mental Component Score (MCS), are suitable to assess a patient's psychological and behavioural style and their health-related quality of life. The study involved 37 Italian out-patients with end-stage renal disease under HD therapy. We calculated the Spearman correlation between variables of CBA-H, SF-36, age and time on HD. We also performed a multivariate linear regression using the CBA-H variables as predictors and PCS and MCS as dependent variables. From the CBA-H, 95% of participants self-reported psychological characteristics comparable to Type A personality, which identifies an anxious, hyperactive and hostile subject. Physical limitations were found to be directly proportional to the time on dialysis (rs = -0.42). The condition of perceived stress worsens the state of mental health (rs = -0.68) and general health perception (rs = -0.44). The condition of vital exhaustion correlates both the PCS and the MCS (ppsychological wellbeing of a dialyzed patient could be due to the combination of several factors, including life parameters, the positive perception of psychosocial outcomes, and the perceived quality of life. A multidisciplinary team (neurologists, psychiatrists, psychologists, and nurses) is essential to plan effective psychological and psychotherapeutic interventions to improve a mind-body integration.

Personal values influence behavior and decision making, but their long-term associations with health-related quality of life (HRQoL), frailty, and mortality are less clear. We studied these associations from midlife to old age in a 26-year follow-up of the Helsinki Businessmen Study (HBS) cohort. In 1974, 1320 clinically healthy men (born 1919-1934) reported in a 12-item questionnaire their personal values. In 2000, a mailed questionnaire, including assessment of HRQoL with RAND-36 (SF-36) instrument, was sent to survivors, and 1025 men responded. In 2000, the presence of phenotypic frailty was assessed using modified Fried criteria including indicators of shrinking, physical weakness, exhaustion, and physical inactivity. Mortality through December 31, 2000 was verified from national registries. Using a factor analysis, the data of the 12-item questionnaire of personal values were loaded in 3 factors: valuing health ("Health"), enjoyable and varying life ("Enjoyment"), and comfort and work-oriented life ("Work-life-balance"). Adjusted for age, we found a significant positive association between valuing "Health" in midlife and RAND-36 domains of Physical functioning (p = .032) and Vitality (p = .005) in old age. "Health" also predicted less frailty (p = .008), and "Enjoyment" was associated with higher mortality (p = .017). Value priorities of men assessed in midlife had long-term associations with HRQoL and frailty in old age, and they may also predict mortality.

The aim of this work was to assess the association among oral health, general health, and quality of life (QoL). The Oral Health Impact Profile (OHIP-49) and the RAND-36 were distributed amongst 118 psychology freshmen. Additionally, two single items self-rated general health (SRGH) and self-rated oral health (SROH) - were administered. Kruskal-Wallis and Mann-Whitney U-tests were used to evaluate differences between SRGH and SROH categories, regarding OHIP subscale scores and RAND subscale scores. More than 75% of the subjects rated their oral and general health as good. Mean OHIP scores and RAND scores indicated a relatively good oral- and general health-related QoL respectively. The correlation between oral and general health was weak. Significant differences were found between SRGH categories regarding RAND subscale scores, except for the 'role emotional' and 'mental health' subscales. Significant differences were also found between SROH categories regarding OHIP subscale scores, except for the 'psychological disability' subscale. However, no significant differences were found between SRGH categories regarding OHIP subscale scores, or between SROH categories regarding RAND subscale scores. The findings suggest that oral health, general health, and QoL have different determinants. Furthermore, oral health and general health appear to be mostly unrelated in this seemingly healthy population. It is proposed that if no apparent disease is present, oral and general health must be regarded as separate constructs.

Global discourse on population, health and development have placed women's health issues at the top of development agenda. Women's reproductive health has received some attention in Ghana since the mid-1990s. However, studies on women's general health status, dimensions and the differentials in a rapidly growing urban setting is poorly understood and under-researched. This study sought to examine the various pathways in which individual socio-demographic factors, economic characteristics and endowment influence self-assessed health status among women living in the city of Accra, Ghana. The paper draws on a cross-sectional study carried out in 2008 and 2009 using a representative sample of urban women 20 years and older (n = 2814). Multivariate stepwise linear regression models were performed to investigate the influence of socio-demographic, economic and health indicators on health-related quality of life, measured by eight sub-scales of the Short Form-36 (SF-36). Interaction effects between some demographic and socio-economic variables were also performed. The analyses show diverse relationships between demographic, socio-economic and health indicators and health outcomes assessed using eight SF-36 sub-scales. Education, disease symptoms and age of the respondent were the most significant factors influencing good overall health status. Interestingly, age has no significant effect on mental health after controlling for all other explanatory variables. The findings show that health issues are multi-faceted requiring socio-cultural, health and economic policy interventions. Investing in women's education is important to improve health status. There is also the need for more effective collaboration across various sectors to improve the health and well-being of women in general. Ageing has increasing relationship with poor physical health status and the elderly should be given needed attention and support.

This study aimed to assess the validity and reliability of World Health Organization Quality of Life Instrument (WHOQOL)-brief and SF-36 in patients with coronary artery disease (CAD). Considering that depression is known to be associated with bad outcomes in CAD and it is highly associated with poor Quality of Life (QOL), we tested the correlation between WHOQOL and SF-36 and an instrument to screen depressive symptoms. It is a cross-sectional survey conducted in 103 patients with documented CAD. QOL was measured through WHOQOL-brief and SF-36 and depressive symptoms were assessed by the Beck Depression Inventory (BDI). To evaluate convergent validity, the correlations between both QOL assessment instruments were examined; discriminant validity was assessed through BDI and QOL instruments correlations. Coefficient Cronbach's alpha was used to test reliability. Percentages of floor and ceiling effects were higher in SF-36 scores than the WHOQOL-brief ones. Although WHOQOL-brief showed a maximum of 1% of floor effect and 9% of ceiling effect, SF-36 presented 40 and 32%, respectively. Internal consistency reliability ranged from 0.65 to 0.85 for the WHOQOL-brief and 0.57 to 0.89 for the SF-36. Correlations between subscales of WHOQOL-brief and BDI ranged from -0.74 to -0.61 and correlations between subscales of SF-36 and BDI ranged from -0.68 to -0.26. SF-36 and WHOQOL-brief seem to be valid and consistent QOL measures in patients with CAD. Researchers should define the aims of their studies before choosing which instrument to use, because they appear to measure different constructs of QOL.

Following total hip arthroplasty, patients' perception of their postoperative improvement and health plays a large role in satisfaction with and success of the surgical procedure. The Short Form-6D (SF-6D) is a health-related quality-of-life measure that assigns numerical value to the perception of patients' own health. The purpose was to determine SF-6D values of patients after total hip arthroplasty, to determine whether score changes were clinically relevant, and to compare these with postoperative functional improvements. We evaluated 188 patients who underwent primary total hip arthroplasty at 7 institutions and who had a mean age of 69 years (range, 47 to 88 years) and a mean body mass index of 28.8 kg/m (range, 19.8 to 38.9 kg/m). The SF-6D values were obtained from patients' SF-36 scores, and clinical relevance of value changes was determined using effect size. Using previous research, effect sizes were considered small between 0.2 and 0.5, moderate between 0.6 to 0.8, and large at >0.8. Clinical correlation was assessed using the Lower-Extremity Activity Scale and Harris hip scores. Patients were assessed preoperatively and postoperatively at 6 months and 1, 2, 3, and 5 years. The SF-6D scores improved from preoperatively and achieved significance (p < 0.05) at all points. The effect size demonstrated good clinical relevance up to the latest follow-up: 1.27 at 6 months, 1.30 at 1 year, 1.07 at 2 years, 1.08 at 3 years, and 1.05 at 5 years. The Lower-Extremity Activity Scale improved at all follow-up points from preoperatively to 1.8 at 6 months, 2.0 at 1 year, 1.8 at 2 years, 1.5 at 3 years, and 1.6 points at 5 years. The Harris hip score improved to 38 points at 6 months, 40 points at 1 year, 38 points at 2 years, 39 points at 3 years, and 41 points at 5 years postoperatively. The improvements in the Lower-Extremity Activity Scale and the Harris hip score significantly positively correlated (p < 0.01) with the SF-6D scores at all time points. SF-6D scores

Full Text Available Background: Pulmonary rehabilitation (PR has inconsistent effects on health-related quality of life (HRQL in patients with chronic lung diseases. We evaluated the effect of PR on HRQL outcomes using the 36-item short form of the medical outcomes (SF-36. Methods : We retrospectively reviewed the files of all patients who completed PR in 2010, 2011, and first half of 2012. We collected information on demographics, symptoms, pulmonary function tests, 6-minute walk tests (6-MWT, and responses on the SF-36 survey, including the physical component score (PCS and mental component score (MCS. Results: The study included 19 women and 22 men. The mean age was 69.8 ± 8.5 years. The diagnoses included chronic obstructive pulmonary disease (COPD; n = 31, asthma (n = 3, interstitial lung disease (n = 5, and obstructive sleep apnea (OSA; n = 2. The mean forced expiratory volume-one second (FEV1 was 1.16 ± 0.52 L (against 60.5 ± 15.9% of predicted value. There was a significant improvement in 6-MWT (P < 0.0001. The PCS improved post-PR from 33.8 to 34.5 (P = 0.02; the MCS did not change. Conclusion: These patients had low SF-36 scores compared to the general population; changes in scores after PR were low. These patients may need frequent HRQL assessment during rehabilitation, and PR programs should consider program modification in patients with small changes in mental health.

Reference values for patient-reported outcome measures are useful for interpretation of results from clinical trials. The study aims were to collect Norwegian SF-36 reference values and compare with data from 1996 to 2002. In 2015, SF-36 was sent by mail to a representative sample of the population (N = 6165). Time trends and associations between background variables and SF-36 scale scores were compared by linear regression models. The 2015 response rate was 36% (N = 2118) versus 67% (N = 2323) in 1996 and 56% (N = 5241) in 2002. Only 5% of the youngest (18-29 years) and 27% of the oldest (>70 years) responded in 2015. Age and educational level were significantly higher in 2015 relative to 1996/2002 (p 36 scores were relatively stable across surveys, controlled for background variables. In general, the most pronounced changes in 2015 were better scores on the role limitations emotional scale (7.4 points, p 70 years. Despite societal changes in Norway the past two decades, HRQoL has remained relatively stable.

Societal preference-weighted health-related quality of life (HRQOL) scores enable comparing multidimensional health states across diseases and treatments for research and policy. To assess the effects of living with a permanent intestinal stoma, compared with a major bowel resection, among colorectal cancer (CRC) survivors. Cross-sectional multivariate linear regression analysis to explain preference-weighted HRQOL scores. In all, 640 CRC survivors (≥ 5 years) from 3 group model health maintenance organizations; ostomates and nonostomates with colorectal resections for CRC were matched on gender, age (± 5 years), time since diagnosis, and tumor site (rectum vs. colon). SF-6D scoring system was applied to Medical Outcomes Study Short Form-36 version 2 (SF-36v2); City of Hope Quality of Life-Ostomy; and Charlson-Deyo comorbidity index. Survey of CRC survivors linked to respondents' clinical data extracted from health maintenance organization files. Response rate was 52%. Ostomates and nonostomates had similar sociodemographic characteristics. Mean SF-6D score was 0.69 for ostomates, compared with 0.73 for nonostomates (P ostomy after other factors were taken into account. Surgical complications, comorbidities, and metastatic disease lowered the preference-weighted HRQOL of CRC survivors with and without ostomies. Further research to understand and reduce late complications from CRC surgeries as well as associated depression is warranted.

Early history and reactivation of the rand thrust, southern California

Science.gov (United States)

Postlethwaite, Clay E.; Jacobson, Carl E.

The Rand thrust of the Rand Mountains in the northwestern Mojave Desert separates an upper plate of quartz monzonite and quartzofeldspathic to amphibolitic gneiss from a lower plate of metagraywacke and mafic schist (Rand Schist). The Rand thrust is considered part of the regionally extensive Vincent/Chocolate Mountain thrust system, which is commonly believed to represent a Late Cretaceous subduction zone. The initial direction of dip and sense of movement along the Vincent/Chocolate Mountain thrust are controversial. Microfabrics of mylonites and quartzites from the Rand Mountains were analyzed in an attempt to determine transport direction for this region, but the results are ambiguous. In addition, the southwestern portion of the Rand thrust was found to have been reactivated as a low-angle normal fault after subduction. Reactivation might have occurred shortly after subduction, in which case it could account for the preservation of high-pressure mineral assemblages in the Rand Schist, or it could be related to mid-Tertiary extension in the western United States. In either event, the reactivation might be responsible for the complicated nature of the microfabrics. The Rand Schist exhibits an inverted metamorphic zonation. Isograds in the schist are not significantly truncated by the reactivated segment of the Rand thrust. This indicates that other segments of the Vincent/Chocolate Mountain thrust should be re-evaluated for the possibility of late movement, even if they show an apparently undisturbed inverted metamorphic zonation.

Limited information exists regarding the natural progression of health-related quality of life (HRQOL) in the general population, as most research has been cross-sectional or has followed populations with specific medical conditions. Such norms are important to establish, because the effect of any intervention may be confounded by changes due to the natural progression of HRQOL over time. Participants were randomly selected from 9 Canadian cities and surrounding rural areas. Changes in the eight domains and 2 summary component scores of the Medical Outcomes Study 36-item short form (SF-36) were examined over a 5 year period (1996/1997-2001/2002). Mean changes were calculated for men and women within 10 year age categories. Multiple imputation was used to adjust for potential selection bias due to missing data. The baseline sample included 6539 women and 2884 men. Loss to follow-up was 17% for women and 23% for men. Mean changes tended to be small, but there was an overall trend towards decreasing HRQOL over time. Changes were more pronounced in the older age groups and in the physically oriented domains. Younger age groups tended towards small mean improvements, particularly in the mentally oriented domains. Large standard errors suggest that on an individual level, large improvements in some participants are balanced by large declines in others. In general, the HRQOL of Canadians appears relatively stable over a 5 year period. However, care should be taken when assessing HRQOL longitudinally in certain age or gender groups, as changes associated with an intervention can potentially be confounded by the natural progression of HRQOL.

Full Text Available Anxiety and health related Quality of Life (HRQoL have emerged as important mental health measures in obstetric care. Few studies have systematically examined the longitudinal trajectories of anxiety and HRQoL in pregnancy. Using a linear growth modeling strategy, we analyzed the course of State-Trait Anxiety Inventory (STAI- and Short Form (36 Health Survey (SF-36 scores between the 12th and the 36th week of gestation, in a sample of 355 women. We additionally analyzed the impact of depressive symptoms and a chronic medical condition (asthma, on STAI and SF-36 trajectory curves. STAI scores remained stable throughout pregnancy. A previous history of anxiety increased the overall STAI scores. Asthma and depressive symptoms scores had no impact on the STAI trajectory. Physical SF-36 scores decreased over the course of pregnancy, whereas mental SF-36 trended towards improvement. Asthma reduced physical SF-36 overall. While high depressive symptoms decreased the overall mental SF-36, they were also significantly associated with mental SF-36 improvements over time. Anxiety symptoms are stable during pregnancy and are not modulated by depressive symptoms or asthma. Physical HRQoL declines in pregnancy. In contrast, mental HRQoL appears to improve, particularly in women with high initial levels of depressive symptoms.

Simple Summary In Italy, dog shelters are overcrowded because the rate of dog adoption is lower than that of abandonment. A project called “RandAgiamo” was implemented in a rescue shelter in central Italy. RandAgiamo provides training, socialization and advertising of adult shelter dogs. Official data of the Umbria regional health authorities from the year 2014 showed a higher rate of adoption in shelters involved in the project. RandAgiamo dogs had triple odds of being adopted compared to others housed in shelters of the same province. The increase in adoption rate can be beneficial for both dog welfare and shelter management. Abstract Current Italian legislation does not permit euthanasia of dogs, unless they are ill or dangerous. Despite good intentions and ethical benefits, this “no-kill policy” has caused a progressive overpopulation of dogs in shelters, due to abandonment rates being higher than adoption rates. Shelter overcrowding has negative implications for dog welfare and increases public costs. The aim of this paper is to describe the pilot project “RandAgiamo” implemented in a rescue shelter in the Umbria Region and to evaluate its effectiveness on the rate of dog adoption using official data. RandAgiamo aimed to increase adult shelter dogs’ adoptability by a standard training and socialization programme. It also promoted dogs’ visibility by publicizing them through social media and participation in events. We analysed the official data of the Umbria regional health authorities regarding dog shelters of the Perugia province of the year 2014. In the RandAgiamo shelter, the dog adoption rate was 27.5% higher than that of dogs housed in other shelters located in the same geographical area (p dogs’ welfare, owner satisfaction, shelter management, and public perception of shelter dogs. However, staff were required to provide dog training and related activities. PMID:26479385

Missing items are common in quality of life (QoL) questionnaires and present a challenge for research in this field. It remains unclear which of the various methods proposed to deal with missing data performs best in this context. We compared personal mean score, full information maximum likelihood, multiple imputation, and hot deck techniques using various realistic simulation scenarios of item missingness in QoL questionnaires constructed within the framework of classical test theory. Samples of 300 and 1,000 subjects were randomly drawn from the 2003 INSEE Decennial Health Survey (of 23,018 subjects representative of the French population and having completed the SF-36) and various patterns of missing data were generated according to three different item non-response rates (3, 6, and 9%) and three types of missing data (Little and Rubin's "missing completely at random," "missing at random," and "missing not at random"). The missing data methods were evaluated in terms of accuracy and precision for the analysis of one descriptive and one association parameter for three different scales of the SF-36. For all item non-response rates and types of missing data, multiple imputation and full information maximum likelihood appeared superior to the personal mean score and especially to hot deck in terms of accuracy and precision; however, the use of personal mean score was associated with insignificant bias (relative bias personal mean score appears nonetheless appropriate for dealing with items missing from completed SF-36 questionnaires in most situations of routine use. These results can reasonably be extended to other questionnaires constructed according to classical test theory.

In epidemiological surveillance of mental health there is good reason to also include scales that measure the presence of well-being rather than merely symptoms of ill health. The Mental Health Continuum-Short Form (MHC-SF) is a self-reported scale to measure emotional, psychological and social well-being and conduct categorical diagnosis of positive mental health. This particular instrument includes the three core components of the World Health Organization's definition of mental health and had previously not been psychometrically evaluated on adolescents in China. In total 5,399 students (51.1% female) from schools in the urban areas of Weifang in China were included in the study (mean age = 15.13, SD = 1.56). Participants completed a comprehensive questionnaire with several scales, among them the MHC-SF. Statistical analyses to evaluate reliability, structural validity, measurement invariance, presence of floor and ceiling effects and to some extent external validity of the MHC-SF were carried out. The Cronbach's α coefficients for sub-scales as well as the total scale were all above 0.80 indicating good reliability. Confirmative factor analysis confirmed the three-dimensional structure of the Chinese version of MHC-SF and supported the configural and metric invariance across gender and age. Noteworthy ceiling effects were observed for single items and sub-scales although not for the total scale. More importantly, observed floor effects were negligible. The stronger correlation found between MHC-SF and Minneapolis-Manchester Quality of Life Instrument (as measure of positive mental health) than between MHC-SF and Hospital Anxiety Depression Scale (as measure of mental illness and distress) yielded support for external validity. In conclusion, the main findings of this study are in line with studies from other countries that evaluated the psychometric properties of the MHC-SF and show that this instrument, that includes the three core components of the

Studies have shown that Mindfulness Based Stress Reduction (MBSR) has positive effect on physical and psychological dimensions of chronic illnesses. In this study for the first time we examine the effect of this new technique on quality of life and pulmonary function in chemically pulmonary injured veterans who have chronic pulmonary problem, psychological problems and low quality of life. Forty male pulmonary injured veterans were randomly replaced in two groups with 20 participants (MBSR and control Wait List (WL)). Then MBSR group received 8-weekly sessions intervention. We evaluate quality of life (used SF-36 questionnaire) and Spirometry parameters two times; before and after intervention in two group. We used "mixed factorial analyses of variance" test for analyzing data in each dependent variables. Then if we have significant interactional effect, we used -paired- sample t-test" for comparing before and after intervention data of each group, and "Independent-Sample t-test" for comparing after intervention data of two groups. The MBSR compare to WL group improved SF-36 total score, (F (1, 38) =12.09, P=0.001), "Role limitations due to physical problems"(F(1,38)= 6.92, P=0.01), "Role limitations due to emotional problems"(F(1,38)= 7.75, P=0.008), "Social functioning"(F(1,38)= 9.89, P=0.003), "Mental health"(F(1,38)= 15.93, P=0), "Vitality"(F(1,38)= 40.03, P≤0.001), and "Pain"(F(1,38)= 27.60, P≤0.001). MBSR had no significant effect on "FEV1" (F (1, 38) = 0.03, P=0.85),"FVC" (F (1, 38) = 0.16, P=0.69) and "FEV1/FVC" (F (1, 38) = 2.21, P=0.14). MBSR can improve individual's quality of life but not lung function in chemically pulmonary injured veterans.

Objectives: Anterior cruciate ligament reconstruction is a commonly performed orthopaedic procedure. PROMIS (Patient-Reported Outcome Measurement Information System) was developed by the National Institutes of Health in an effort to advance patient-reported outcome (PRO) instruments by developing question banks for major health domains. Our goal was to compare the responsiveness and construct validity of the PROMIS physical function (PF) computer adaptive test (CAT) with current PRO instruments utilized in patients who undergo anterior cruciate ligament reconstruction. Methods: A total of 174 patients ages 14-53 scheduled to undergo anterior cruciate ligament reconstruction were asked to complete PROMIS PF-CAT, Short Form-36 Health Survey (SF36-PF and -GH), Marx activity rating scale (Marx), Knee Injury and Osteoarthritis Score (KOOS-ADL, -Sport, -QOL), and the EuroQol five dimensions questionnaire (EQ5D) at their preoperative visit. These surveys were repeated at six weeks and six months after surgery. Correlations between PRO instruments was defined as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), and poor (0.2-0.3) using Spearman Correlation Coefficients. The effect size (Cohen d) and standardized response mean (SRM) were used to describe the responsiveness of each PRO at the 6 week and 6 month follow-up visits and were defined as small (0.2), medium (0.5) and large (0.8). Ceiling and floor effects were defined as present if ≥15% of participants scored the highest or lowest score on a PRO, respectively. Subgroup analyses were performed comparing change in PRO scores at follow-up between participants with and without additional arthroscopic procedures (meniscal debridement and/or repair, microfracture, or OATS vs ACL reconstruction only) using linear mixed models. Results: There were excellent and excellent-good correlations between the PROMIS PF-CAT and physical function PROs including the SF36-PF (r=0.75-0.80, p0.05) to poor correlation with

OBJECTIVE To assess health-related quality of life (HRQOL) in men with erectile dysfunction. DESIGN Descriptive survey with general and disease-specific measures. The instrument contained three established, validated HRQOL measures, a validated comorbidity checklist, and sociodemographics. The RAND 36-Item Health Survey 1.0 (SF-36) was used to assess general HRQOL. Sexual function and sexual bother were assessed using the UCLA Prostate Cancer Index. The marital interaction scale from the Cancer Rehabilitation Evaluation System Short Form (CARES-SF) was used to assess each patient's relationship with his sexual partner. SETTING Urology clinics at a university medical center and the affiliated Veterans Affairs (VA) Medical Center. PARTICIPANTS Thirty-five (67%) of 54 consecutive university patients presenting for erectile dysfunction and 22 (42%) of 52 VA patients who were awaiting a previously prescribed vacuum erection device participated. MAIN RESULTS The university respondents scored slightly lower than population normals in social function, role limitations due to emotional problems, and emotional well-being. The VA respondents scored lower than expected in all eight domains. Scores for the VA population were significantly lower than those for the university population in physical function, role limitations due to physical problems, bodily pain, and social function. A significant correlation was seen between marital interaction and sexual function (r = −.33, p = .01) but not between marital interaction and sexual bother (r = −.15, p = .26) in the total sample. Sexual function also correlated significantly with general health perceptions (r = .34, p = .01), role limitations due to physical problems (r = .29, p = .03), and role limitations due to emotional problems (r = .30, p = .03). Sexual bother did not correlate with any of the general HRQOL domains. Affluent men reported better sexual function (p = .03). CONCLUSIONS The emotional domains of the SF-36 are

Health-related quality of life (HR-QoL) is impaired in patients with hereditary angioedema (HAE) but has not yet been satisfactorily described. To study HR-QoL in patients with HAE by combining different HR-QoL instruments with disease activity assessment. All adults in the Swedish HAE registry were invited to take part in this questionnaire study, which used the generic HR-QoL instruments, EuroQol 5 Dimensions 5 Level (EQ-5D-5L) and the RAND Corporation Short Form 36 (RAND-36), the disease-specific Angioedema Quality of Life instrument (AE-QoL), the recently introduced Angioedema Activity Score (AAS) form, and questionnaires on sick leave and prophylactic medication. Sixty-four of 133 adults (26 men, 38 women) between 18 and 91 years old responded. The most affected HR-QoL dimensions in the EQ-5D-5L were pain/discomfort and anxiety/depression; in the RAND-36, energy/fatigue, general health, pain; and, in the AE-QoL, fears/shame and fatigue/mood. Women had lower HR-QoL in the RAND-36 for general health and energy/fatigue (p 0 had significantly impaired HR-QoL. There were significant associations (p depression, and fatigue/mood are important aspects of HAE but the AE-QoL disregards pain. HR-QoL was not significantly affected by prophylaxis. Increased disease activity was associated with impaired HR-QoL, which justifies more active disease management.

Full Text Available This study investigates the behaviour of the volatility in the South African Rand/USD exchange rate and its impact on the value of the Rand between 2001 and 2017. The key objectives were to assess the impact of its volatility on its market value, and determine the presence of asymmetric effect in the times path of the volatility, resulting from shocks to its market value. From the estimates of our EGARCH-M (1,1 model, we found the value of the Rand to respond negatively to volatility it is time path, suggesting that the Rand appreciates more in value under conditions of less tranquillity. In addition, we found evidence of asymmetric effect, of shocks to the conditional mean, in the conditional variance of the Rand. The asymmetric effect is such that negative shocks to the conditional mean, which causes the Rand to appreciate, have more impact on next point volatility in the Rand than positive shocks of the same magnitude, which causes depreciation in its value.

Patients suffering from fibromyalgia (FM) had widespread musculoskeletal pain and stiffness, fatigue, sleep disorders, cognitive impairment and other symptoms, which seriously affects their quality of life (QoL), making it difficult to perform normal activities. Moreover, FM has been associated with a higher prevalence of overweight and obesity than in the general population. Weight reduction has been beneficial in both FM and other rheumatic patients. Obesity and overweight have been pointed as playing a relevant role in FM symptoms; however, it is necessary to find out more about this relationship. The objective of this study was to evaluate the relationship between body mass index (BMI), fat mass (fM) and lean mass (lM) with quality of life in a group of FM patients. 103 women, with a mean age of 53.74 ± 7.81, and members of different FM patient associations from Spain participated in our study. Some anthropometric measures were taken like weight, height, BMI, body fat mass and lean mass. FM patients QoL was assessed by the Short-Form Health Survey, SF-36 questionnaire. Statistical reports were based on mean, standard deviation and correlation, but significance was tested by nonparametric methods. BMI, fM and lM correlated differently with the specific SF-36 scores. BMI had a high negative correlation with emotional role, fM with bodily pain and lM almost with all scores but specially with emotional role, vitality and physical role. The outcome of this study reveals some interesting relationships, which need to be further investigated to improve the management of FM patients.

Full Text Available Abstract Background Longitudinal studies analyzing the correlations between disease-specific and generic health status questionnaires at different time points in patients with advanced COPD are lacking. The aim of this study was to determine whether and to what extent a disease-specific health status questionnaire (Saint George’s Respiratory Questionnaire, SGRQ correlates with generic health status questionnaires (EuroQol-5-Dimensions, EQ-5D; Assessment of Quality of Life instrument, AQoL; Medical Outcomes Study 36-Item Short-Form Health Survey, SF-36 at four different time points in patients with advanced COPD; and to determine the correlation between the changes in these questionnaires during one-year follow-up. Methods Demographic and clinical characteristics were assessed in 105 outpatients with advanced COPD at baseline. Disease-specific health status (SGRQ and generic health status (EQ-5D, AQoL, SF-36 were assessed at baseline, four, eight, and 12 months. Correlations were determined between SGRQ and EQ-5D, AQoL, and SF-36 scores and changes in these scores. Agreement in direction of change was assessed. Results Eighty-four patients (80% completed one-year follow-up and were included for analysis. SGRQ total score and EQ-5D index score, AQoL total score and SF-36 Physical Component Summary measure (SF-36 PCS score were moderately to strongly correlated. The correlation of the changes between the SGRQ total score and EQ-5D index score, AQoL total score, SF-36 PCS, and SF-36 Mental Component Summary measure (SF-36 MCS score were weak or absent. The direction of changes in SGRQ total scores agreed slightly with the direction of changes in EQ-5D index score, AQoL total score, and SF-36 PCS score. Conclusions At four, eight and 12 months after baseline, SGRQ total scores and EQ-5D index scores, AQoL total scores and SF-36 PCS scores were moderately to strongly correlated, while SGRQ total scores were weakly correlated with SF-36 MCS scores

Programs focused on employee well-being have gained momentum in recent years, but few have been rigorously evaluated. This study evaluates the effectiveness of an intervention designed to enhance vitality and purpose in life by assessing changes in employee quality of life (QoL) and health-related behaviors. A worksite-based randomized controlled trial. Twelve eligible worksites (8 randomized to the intervention group [IG] and 4 to the wait-listed control group [CG]). Employees (n = 240) at the randomized worksites. A 2.5-day group-based behavioral intervention. Rand Medical Outcomes Survey (MOS) 36-item Short-Form (SF-36) vitality and QoL measures, Ryff Purpose in Life Scale, Center for Epidemiologic Studies questionnaire for depression, MOS sleep, body weight, physical activity, diet quality, and blood measures for glucose and lipids (which were used to calculate a cardiometabolic risk score) obtained at baseline and 6 months. General linear mixed models were used to compare least squares means or prevalence differences in outcomes between IG and CG participants. As compared to CG, IG had a significantly higher mean 6-month change on the SF-36 vitality scale ( P = .003) and scored in the highest categories for 5 of the remaining 7 SF-36 domains: general health ( P = .014), mental health ( P = .027), absence of role limitations due to physical problems ( P = .026), and social functioning ( P = .007).

To determine the validity and reliability of Short Form 36 Version 2 (SF36v2) in sub-groups of individuals with fatigue. Thirty subjects participated in this study, including n = 16 subjects who met case definition criteria for chronic fatigue syndrome (CFS) and n = 14 non-disabled sedentary matched control subjects. SF36v2 and Multidimensional Fatigue Inventory (MFI-20) were administered before two maximal cardiopulmonary exercise tests (CPETs) administered 24 h apart and an open-ended recovery questionnaire was administered 7 days after CPET challenge. The main outcome measures were self-reported time to recover to pre-challenge functional and symptom status, frequency of post-exertional symptoms and SF36v2 sub-scale scores. Individuals with CFS demonstrated significantly lower SF36v2 and MFI-20 sub-scale scores prior to CPET. Between-group differences remained significant post-CPET, however, there were no significant group by test interaction effects. Subjects with CFS reported significantly more total symptoms (p validity to identify subjects who recovered from CPET challenge within 1 day and 7 days (p reliability and validity for clinical and research applications. Adequacy of sensitivity to change of SF36v2 as a result of a fatiguing stressor should be the subject of additional study.

Full Text Available Objective. A system analysis of the self-assessments of quality of life (QOL and the possible rational correction of psychological dysadaptation of nursing women. Materials and Methods. A survey among 134 healthy women aged 21 to 40, married and having children aged 1 to 12 months at the time of the survey. The first group consisted of women with breast-fed children (1 to 6 months old and “exclusively breastfed” or 6 to 12 months old and receiving “rational breast feeding”; the second group consisted of women with formula-fed children. The non-specific SF-36 questionnaire has been used for the survey. Statistica 6.0 licensed software has been used for statistical processing of gathered scores. Results. The breast-feeding women (Group 1 showed higher total results in self-assessment of the quality of life compared to the women forced to feed their children with breast milk substitutes (Group 2. The difference affects all 8 scales of the questionnaire, thus varying from the a priori values of the “null hypothesis” (χ2=5.33, df=1 with statistical error probability of p=0.02. The most significant differences of the SF-36 questionnaire assessment indicator scores between the two groups have been identified on BP (intensity and frequency of pain and MH (mental health scales. Conclusions. Our observations have shown significant differences of self-assessments of QOL by women feeding their children in different ways. Breast feeding leads to positive changes in the system of self-assessment of QOL, the lives of nursing women are characterized by greater social support and role activity; they are more socially adapted, not prone to depression and unreasonable mood swings.

Subjective health status is an increasingly important parameter to assess the effect of percutaneous coronary intervention (PCI) in clinical practice. Aim of this study was to determine medical and psychosocial predictors of poor subjective health status over a 10 years' post-PCI period. We included a series of consecutive PCI patients (n = 573) as part of the RESEARCH registry, a Dutch single-center retrospective cohort study. These patients completed the 36-item Short-Form Health Survey (SF-36) at baseline and 10 years post-PCI. We found 6 predictors of poor subjective health status 10 years post-PCI: SF-36 at baseline, age, previous PCI, obesity, acute myocardial infarction as indication for PCI, and diabetes mellitus (arranged from most to least numbers of sub domains). SF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10 years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10 years post-PCI.

We aimed to evaluate the measurement properties of the Singapore English and Chinese versions of the Short-Form 36 version 2 (SF-36v2) Questionnaire, an improved version of the widely used SF-36, for assessing health-related quality of life (HRQoL) in a multi-ethnic urban Asian population in Singapore. SF-36v2 scores and data on medical history, demographic and lifestyle factors from the Singapore Prospective Study Programme were analyzed. Convergent and divergent validity, internal consistency, floor and ceiling effects, known group validity and factor structure of the SF-36v2 were assessed for the English and Chinese versions, respectively. Complete data for 4,917 participants (45.8 %) out of 10,747 eligible individuals were analyzed (survey language: 4,115 English and 802 Chinese). Item-scale correlations exceeded 0.4 for all items of the English SF-36v2 and for all except one item of the Chinese SF-36v2 (bathe and dress: item-scale correlation: 0.36). In the English SF-36v2, Cronbach's alpha exceeded 0.70 for all scales. In the Chinese SF-36v2, Cronbach's alpha exceeded 0.7 on all scales except social functioning (Cronbach's alpha: 0.68). For known groups validity, respondents with chronic medical conditions expectedly reported lower SF-36v2 score on most English and Chinese SF-36v2 scales. In confirmatory factor analysis, the Singapore three-component model was favored over the United States two-component and Japan three-component models. The English and Chinese SF-36v2 are valid and reliable for assessing HRQoL among English and Chinese-speaking Singaporeans. Test-retest reliability and responsiveness of the English and Chinese SF-36v2 in Singapore remain to be evaluated.

To investigate the association between smoking and health-related quality of life (HRQOL) in a rural Japanese population. A cross-sectional study of data from 823 subjects in Iwaki area of Hirosaki City, Japan. SF-36 scores between non-smokers and smokers were compared. To test the sensitivity of SF-36 scores in detecting health deterioration, effects of having diseases and having deviations from normal thresholds in health check-up were analyzed by adding them into covariates in ANCOVA. There was no significant difference in SF-36 scores between non-smokers and smokers. Presence of diseases significantly decreased the physical components of SF-36 scores while the results of health check-up had no significant influence on SF-36 scores. The results suggested the possibility that in Japan, where smoking prevalence is still relatively high, smokers may be less sensitive to sub-clinical deterioration in their own health status than smokers in Western countries that already have experienced the major decline in their smoking rate. The importance of having the smoker become more sensitive to the sub-clinical adverse effects of cigarette smoking should be stressed for the success of smoking control programs.

Current Italian legislation does not permit euthanasia of dogs, unless they are ill or dangerous. Despite good intentions and ethical benefits, this 'no-kill policy' has caused a progressive overpopulation of dogs in shelters, due to abandonment rates being higher than adoption rates. Shelter overcrowding has negative implications for dog welfare and increases public costs. The aim of this paper is to describe the pilot project "RandAgiamo" implemented in a rescue shelter in the Umbria Region and to evaluate its effectiveness on the rate of dog adoption using official data. RandAgiamo aimed to increase adult shelter dogs' adoptability by a standard training and socialization programme. It also promoted dogs' visibility by publicizing them through social media and participation in events. We analysed the official data of the Umbria regional health authorities regarding dog shelters of the Perugia province of the year 2014. In the RandAgiamo shelter, the dog adoption rate was 27.5% higher than that of dogs housed in other shelters located in the same geographical area (P < 0.001). The RandAgiamo project could be beneficial for the dogs' welfare, owner satisfaction, shelter management, and public perception of shelter dogs. However, staff were required to provide dog training and related activities.

Health-related quality of life (HRQOL) reflects the general well-being of individuals. In patients with coronary artery disease (CAD), HRQOL is compromised. Female patients with CAD have been reported to have lower HRQOL. In this study, we investigate gender differences in HRQOL and in associations of patient characteristics with HRQOL in patients with coronary angiography (CAG). We cross-sectionally analysed patients from the Utrecht Coronary Biobank undergoing CAG. All patients filled in an HRQOL questionnaire (RAND-36 and EuroQoL) on inclusion. RAND-36 and EuroQoL HRQOL measures were compared between the genders across indications for CAG, CAD severity and treatment of CAD. RAND-36 HRQOL measures were compared with the general Dutch population. Additionally, we assessed interactions of gender with patient characteristics in their association with HRQOL (EuroQoL). We included 1421 patients (1020 men and 401 women) with a mean age of 65 in our analysis. Women reported lower HRQOL measures than men (mean EuroQoL self-rated health grade 6.84±1.49 in men, 6.46±1.40 in women, pgender differences were found in determinants of HRQOL in patients undergoing CAG, which deserve attention in future research.

Hand eczema is a disease of long duration, affecting the individual and society. The purpose of this study of 100 patients (51 females and 49 males) at an occupational dermatology clinic was to investigate whether the generic questionnaire Short Form-36 (SF-36), and the dermatology-specific Dermatology Life Quality Index (DLQI) are appropriate for assessing health-related quality of life (HRQL) in patients with hand eczema, and whether gender differences in HRQL could be detected. HRQL was affected by hand eczema, measured with both SF-36 and DLQI. The SF-36 showed more impaired HRQL for females than for males, in the mental health dimension, whereas no gender-related differences were detected with the DLQI. To compare the instruments we used factor analysis, with a polychoric correlation matrix as input, thus taking the ordinal aspect of the data into account. There was a high correlation between the instruments for physical health, but lower for mental health. In this context our interpretation of the factor analysis is that the SF-36 measures mental health better than the DLQI. The SF-36 therefore appears suitable for use in future studies for measuring HRQL, and gender differences in HRQL, in persons with reported hand eczema.

The Medical Outcomes Study Short Form 36 (SF-36) and Lupus Quality of Life (LupusQoL) are health-related quality of life questionnaires used in systemic lupus erythematosus (SLE). We first determined the hypothesis-testing construct validity of the SF-36 and LupusQoL against disease activity in patients with active SLE and then compared the sensitivity to change of SF-36 and LupusQoL domains according to different definitions of minimum clinically important differences (MCIDs) for improvement and worsening in the current cohort. Seventy-eight clinically active SLE patients concurrently completed both questionnaires at their baseline and followup visits. Questionnaire domain scores were correlated with the SLE Disease Activity Index 2000 (SLEDAI-2K) and evaluated for floor/ceiling effects. The sensitivity to change of domains in each questionnaire was analyzed first, according to the various MCID definitions and, second, by clinically meaningful changes in disease activity. The magnitudes of change in each domain score between the baseline and followup visit were evaluated using standardized response means. In the 78 patients, the mean ± SD SLEDAI-2K scores were 9.7 ± 4.8 at baseline and 8.8 ± 5.1 at followup. SF-36/LupusQoL domain scores did not correlate with disease activity. The SF-36 showed floor effects, and ceiling effects were evident in both questionnaires. All domains of both questionnaires showed sensitivity to change over time. Specific domains that reflected worsening or improvement differed according to differing MCID definitions. In SLE patients with active disease, both the SF-36 and LupusQoL are sensitive to change, reflecting both improvement and worsening. More importantly, the LupusQoL SLE-specific domains (planning, burden to others, body image, and intimate relationships) were largely responsive to change. © 2017, American College of Rheumatology.

Full Text Available Abstract Background Few studies have evaluated the health-related quality of life (HRQOL of Southern Chinese with chronic hepatitis B (CHB infection. Aim To evaluate the HRQOL of Chinese patients at different stages of CHB infection and to find out factors associated with HRQOL. Methods 520 Chinese adult CHB patients of whom 156 were uncomplicated, 102 had impaired liver function, 139 had cirrhosis and 123 had hepatocellular carcinoma (HCC were interviewed with a structured questionnaire, the SF-36 Health Survey version 2 (SF-36v2, and the Chronic Liver Disease Questionnaire (CLDQ. The differences in SF-6D health preference values and SF-36v2 scores between each CHB group and Hong Kong population norms were assessed by t-test. ANOVA was used to compare the mean SF-6D health preference, SF-36v2 scores, and CLDQ scores among CHB groups. Multiple linear regressions were performed to identify determinants of HRQOL. Results CHB patients had significantly lower SF-36v2 scores than the population norm. The SF-6D values of CHB patients with uncomplicated disease, impaired liver function, HCC and cirrhosis were 0.755, 0.745, 0.720 and 0.701, respectively, all significantly lower than the population norm of 0.787. Advanced stage of CHB illness, anti-viral treatment, bilirubin level, psychological co-morbidity, younger age and female were associated with poorer HRQOL. Conclusion CHB infection had a negative impact on HRQOL. There was a progressive decrease in health preference values with CHB disease progression. The results can be used for the estimation of quality adjusted life years (QALYs for CHB patients in cost effectiveness or cost utility studies.

The study aimed to explore the association between the presence of several protective health behaviors and physical and mental wellbeing/functioning among healthy hospital employees in Greece. A randomly selected representative sample of 395 employees working in seven hospitals, both public and private, within the wider region of Athens participated in the study. Participants were assigned to the following professional categories: administrative, auxiliary and technical personnel, medical doctors and nurses. Four basic protective health behaviors were examined: following the Mediterranean diet, exercising, no smoking and moderate alcohol drinking. Employees' health related quality of life was assessed with the self-administered SF-36 generic health status measure. Technical and administrative hospital personnel reported more healthy behaviors than medical and auxiliary personnel. There was an increased likelihood of scoring higher in almost all SF-36 Physical health subscales in the accumulation of the above four protective heath behaviors. In terms of mental health, even the presence of two or more protective health behaviors significantly increase the score on most SF-36 Mental health subscales. Results indicate that the protective role of basic health behaviors extends beyond physical health to mental wellbeing.

The Centers for Medicare & Medicaid Services require that dialysis patients' health-related quality of life be assessed annually. The primary instrument used for this purpose is the Kidney Disease Quality of Life 36-Item Short-Form Survey (KDQOL-36), which includes the SF-12 as its generic core and 3 kidney disease-targeted scales: Burden of Kidney Disease, Symptoms and Problems of Kidney Disease, and Effects of Kidney Disease. Despite its broad use, there has been limited evaluation of KDQOL-36's psychometric properties. Secondary analyses of data collected by the Medical Education Institute to evaluate the reliability and factor structure of the KDQOL-36 scales. KDQOL-36 responses from 70,786 dialysis patients in 1,381 US dialysis facilities that permitted data analysis were collected from June 1, 2015, through May 31, 2016, as part of routine clinical assessment. We assessed the KDQOL-36 scales' internal consistency reliability and dialysis facility-level reliability using coefficient alpha and 1-way analysis of variance. We evaluated the KDQOL-36's factor structure using item-to-total scale correlations and confirmatory factor analysis. Construct validity was examined using correlations between SF-12 and KDQOL-36 scales and "known groups" analyses. Each of the KDQOL-36's kidney disease-targeted scales had acceptable internal consistency reliability (α=0.83-0.85) and facility-level reliability (r=0.75-0.83). Item-scale correlations and a confirmatory factor analysis model evidenced the KDQOL-36's original factor structure. Construct validity was supported by large correlations between the SF-12 Physical Component Summary and Mental Component Summary (r=0.40-0.52) and the KDQOL-36 scale scores, as well as significant differences on the scale scores between patients receiving different types of dialysis, diabetic and nondiabetic patients, and patients who were employed full-time versus not.

Patient-reported outcomes like health-related quality of life (HRQL) have become increasingly important for full assessment of patients with chronic liver diseases (CLD). To explore the relative impact of different types of liver disease on HRQL as well as predictors of HRQL domains in CLD. Our HRQL databases with Short-Form 36 (SF-36) data were used. Scores for each of SF-36 scales (PF - physical functioning, RP - role functioning, BP - bodily pain, GH - general health, VT - vitality, SF - social functioning, RE - role emotional and MH - mental health, MCS - mental component score, PCS - physical component score) were compared between different types of CLD as well as other variables. Complete data were available for 1103 CLD patients. Demographic and clinical data included: age 54.2 +/- 12.0 years, 40% female, 761 (69%) with cirrhosis. Analysis revealed that age correlated significantly (P < 0.05) with worsening HRQL on every scale of the SF-36. Female patients had more HRQL impairments in PF, RP, BP, GH, VT and MH scales of SF-36 (Delta scale score: 6.6-10.7, P < 0.05). Furthermore, cirrhotic patients had more impairment of HRQL in every scale of SF-36 (Delta scale score: 6.6-43.0, P < 0.05). In terms of diagnostic groups, non-alcoholic fatty liver disease patients showed more impairment of HRQL. Analysis of this large CLD cohort suggests that a number of important clinicodemographic factors are associated with HRQL impairment. These findings contribute to the full understanding of the total impact of CLD on patients' health.

According to Antonovsky's salutogenic concept, a strong sense of coherence is associated with physical and psychological health. The goal of this study was to analyze the association of Antonovsky's sense of coherence with physical and psychosocial health components in patients with hip and knee osteoarthritis before and after in- and outpatient rehabilitation. Prospective cohort study with 335 patients, 136 (41%) with hip and 199 (59%) with knee osteoarthritis. The outcome was measured by Short Form-36 (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Sense of Coherence (SOC-13). Baseline scores of the SF-36 and WOMAC scales and the observed effect sizes after rehabilitation were correlated with the baseline SOC-13. These correlations of the SF-36 scales were compared to the Factor Score Coefficients for the Mental Component Summary of SF-36, which quantify the factor load on the psychosocial dimension. Predictive impact of the baseline SOC-13 for the SF-36 and WOMAC scales (baseline scores and effect sizes) was then determined by multivariate linear regression controlled for possible confounders. At baseline, the SOC-13 correlated with the WOMAC scores between r = 0.18 (stiffness) and r = 0.25 (pain) and with the SF-36 scores between r = 0.10 (physical functioning) and r = 0.53 (mental health). The correlation of these SF-36 correlation coefficients to the Factor Score Coefficient of the SF-36 Mental Component Summary was r = 0.95. The correlations for the effect sizes (baseline → discharge) with the baseline SOC-13 global score were all negative and varied between r = 0.00 (physical functioning) and r = -0.19 (social functioning). In the multivariate linear regression model, the explained variance of the SF-36 scores by the baseline SOC-13 increased continuously from physical to psychosocial health dimensions (from 12.9% to 29.8%). This gradient was consistently observed for both the baseline

Perennial allergic rhinitis impairs social life, but it is not known whether quality of life may be improved when patients are treated with an H1-blocker. A randomized, double-blind, placebo-controlled study was carried out with cetirizine to assess the effect of this drug on quality of life. Two hundred seventy-four patients with perennial allergic rhinitis were tested. Quality of life was measured by using the Medical Outcome Study Short-Form Health Survey (SF-36) questionnaire. After a 2-week run-in period, cetirizine, 10 mg once daily, (136 patients) or placebo (138 patients) was given for the next 6 weeks. The SF-36 questionnaire was administered after the run-in period (at the start of treatment) and after 1 and 6 weeks of treatment. Symptom-medication scores were measured daily during the study. After the run-in period (baseline), there were no significant differences between the cetirizine and placebo groups in terms of symptoms or quality-of-life scores. After 6 weeks of treatment, percentage of days without rhinitis or with only mild rhinitis symptoms was significantly greater in the cetirizine group in comparison with the placebo group (p < 0.0001, Mann-Whitney U test). All of the nine quality-of-life dimensions were significantly improved (from p = 0.01 to p < 0.0001, Mann-Whitney U test) after 1 and 6 weeks of cetirizine treatment compared with placebo. There was no improvement in the placebo group. This study is the first to demonstrate that an H1-blocker, cetirizine, can improve quality of life for patients with perennial allergic rhinitis.

Independent from noise exposure, noise sensitivity plays a pivotal role in people's noise annoyance perception and concomitant health deteriorations. The present study empirically investigated the psychometric properties of the Chinese version of the Weinstein Noise Sensitivity Scale-Short Form (CNSS-SF), the widely used inventory measuring individual differences in noise perception. In total, 373 Chinese participants (age = 21.41 ± 3.36) completed the online, anonymous questionnaire package. Examination of the CNSS-SF's reliability (internal consistency), factorial validity through validation and cross-validation, nomological validity and measurement invariance across gender groups were undertaken. The Cronbach alpha coefficients and composite reliabilities indicated sufficient reliability of the CNSS-SF. Two confirmatory factor analyses (CFA), in two randomly partitioned groups of participants, substantiated the factorial validity of the scale. The nomological validity of the scale was also corroborated by the significant positive association of its score with the trait anxiety score. Measurement invariance of the CNSS-SF was also found across genders via multi-group CFA. Though not without limitations, findings from the present research provide promising evidence for the utility of the scale in measuring noise sensitivity among the Chinese population. The availability of the CNSS-SF can promote research related to environmental noise and health in China, as well as facilitate cross-cultural comparisons.

2013-02-01

This systematic review was conducted to identify generic health related quality of life (HRQL) measures translated into Arabic, and evaluate their cross-cultural adaptation and measurement properties. Six databases were searched, relevant journals were hand searched, and reference lists of included studies were reviewed. Previously established criteria were used to evaluate the cross-cultural adaptation of the identified instruments and their measurement properties. Twenty studies that reported the Arabic translations and adaptations of HRQL measures and/or their measurement properties were included in this review. The identified instruments were SF-36, RAND-36, WHOQOL-Bref, COOP/WONCA charts, EQ-5D, and QLI. Cross-cultural adaptations of all measures were of moderate to good quality, and evaluation of measurement properties was limited due to insufficiency of evidence. Based on cross-cultural adaptation evaluation, each instrument is more applicable to the population for whom it was adapted, and to other Arabic populations of similar culture and language specific idioms. This review facilitates the selection among existing Arabic versions of generic HRQL for use in particular Arabic countries. However, each of the translated versions requires further investigation of measurement properties before more concrete recommendations could be made.

Major burns are likely to have a strong impact on health-related quality of life (HRQoL). We investigated the level of and predictors for quality of life at 6 months after acute burn. Consecutive acute adult burn patients (n=107) admitted to the Helsinki Burn Centre were examined with a structured diagnostic interview (SCID) at baseline, and 92 patients (86%) were re-examined at 6 months after injury. During follow-up 55% (51/92) suffered from at least one mental disorder. The mean %TBSA was 9. TBSA of men did not differ from that of women. Three validated instruments (RAND-36, EQ-5, 15D) were used to evaluate the quality of life at 6 months. All the measures (RAND-36, EQ-5, 15D) consistently indicated mostly normal HRQoL at 6 months after burn. In the multivariate linear regression model, %TBSA predicted HRQoL in one dimension (role limitations caused by physical health problems, p=0.039) of RAND-36. In contrast, mental disorders overall and particularly major depressive disorder (MDD) during follow-up (p-values of 0.001-0.002) predicted poor HRQoL in all dimensions of RAND-36. HRQoL of women was worse than that of men. Self-perceived HRQoL among acute burn patients at 6 months after injury seems to be mostly as good as in general population studies in Finland.

Both oral and global health-related quality of life (HRQoL) are markedly impaired in SSc. In this study we aimed to determine the degree of association between oral HRQoL and global HRQoL in SSc. Subjects were recruited from the Canadian Scleroderma Research Group registry. Global HRQoL was measured using the Medical Outcomes Trust 36-item Short Form Health Survey (SF-36) and oral HRQoL with the Oral Health Impact Profile (OHIP). The Medsger Disease Severity Score was used to determine organ involvement. Multivariate regression models determined the independent association of the OHIP with the SF-36 after adjusting for confounders. This study included 156 SSc subjects. The majority (90%) were women, with a mean age of 56 years, mean disease duration 13.8 years (s.d. 8.5) and 29% of the subjects had dcSSc. Mean total OHIP score was 40.8 (s.d. 32.4). Mean SF-36 mental component summary (MCS) score was 49.7 (s.d. 11.1) and physical component summary (PCS) score was 37.0 (s.d. 10.7). In adjusted analyses, the total OHIP score was significantly associated with the SF-36 MCS and PCS, accounting for 9.7% and 5.6% of their respective variances. Measures of disease severity were not related to OHIP score. Oral HRQoL in SSc is independently associated with global HRQoL. Oral HRQoL, however, is not related to physician-assessed disease severity. This suggests that physicians may be disregarding issues related to oral health. HRQoL is an additional dimension of HRQoL not captured by generic instruments such as the SF-36. © The Author 2014.

To assess the value of health education (active management and postural hygiene) over and above exercise alone, in patients with chronic low back pain. Adults (aged 18-30 years) with low back pain of ≥ 3 months' duration were randomized to undergo a 12-week programme of lumbar strengthening exercise and health education or exercise alone. Pain, disability (Oswestry Disability Index, ODI), static and dynamic muscle endurance, and health-related quality-of-life (short form-36, SF-36) were assessed at baseline and after completion of treatment. At the end of the 12-week intervention period, pain, disability, SF-36 physical component and SF-36 mental component were significantly better in the health education group (n = 25) than in the control group (n = 24). There were no significant between-group differences in static or dynamic endurance. Health education provides additional benefits to exercise alone for improving pain, disability and mental and physical health-related quality-of-life. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

To assess the potential of various plasma lipoprotein classes to contribute to the lipid content of the arterial intima, influx and efflux of these plasma lipoprotein fractions into and from the intima of human carotid arteries were measured in vivo. While low density lipoprotein (LDL) is known to transfer from plasma into the arterial wall, there is less information on the atherogenic potential of lipoproteins of intermediate density (Sf 12-60) or of very low density (Sf 60-400). Aliquots of the same lipoprotein (LDL, Sf 12-60 lipoprotein particles, or Sf 60-400 lipoprotein particles) iodinated with iodine-125 and iodine-131 were injected intravenously 18-29 hours and 3-6 hours, respectively, before elective surgical removal of atheromatous arterial tissue, and the intimal clearance of lipoproteins, lipoprotein influx, and fractional loss of newly entered lipoproteins were calculated. Intimal clearance of Sf 60-400 particles was not detectable (less than 0.3 microliter x hr-1 x cm-2), whereas the average value for both LDL and Sf 12-60 lipoprotein particles was 0.9 microliter x hr-1 x cm-2. Since the fractional loss of newly entered LDL and Sf 12-60 lipoprotein particles was also similar, the results suggest similar modes of entry and exit for these two particles. However, due to lower plasma concentrations of Sf 12-60 lipoproteins as compared with LDL, the mass influx of cholesterol in the Sf 12-60 particles was on the order of one 10th of that in LDL, and that of apolipoprotein B was about one 20th

The objective of this study was to evaluate health related quality of life (HRQOL) using the Medical Outcomes Study 8-items Short Form Health Survey (SF-8) questionnaire in Japanese patients with early prostate cancer. A cross-sectional analysis was done in 457 patients with prostate cancer treated with radical prostatectomy, external beam radiotherapy, brachytherapy, androgen deprivation therapy, and watchful waiting or a combination these therapies. General HRQOL was measured using the Japanese version of the SF-8 questionnaire and disease-specific HRQOL was assessed using the Japanese version of the Extended Prostate Cancer Index Composite. The external beam radiotherapy group reported significantly lower values for the physical health component summary score (PCS) in comparison to the radical prostatectomy and brachytherapy groups (P<0.05). In the analysis of both the PCS and the mental health component summary score (MCS) over time after treatment, higher scores with time were found in the radical prostatectomy group. No significant change over time after androgen deprivation therapy in the PCS was found. In contrast, the MCS was found to deteriorate in the early period, showing a significant increase over time. SF-8 in combination with the Extended Prostate Cancer Index Composite has shown to be a helpful tool in the HRQOL assessment of Japanese patients treated for localized prostate cancer. (author)

Full Text Available Abstract Background Burning mouth syndrome is a chronic disorder that is characterized by a burning sensation and a normal clinical appearance of the oral mucosa. This condition often affects the health-related quality of life in patients. As such, the aim of this study was to compare the health-related quality of life of patients with BMS and healthy controls, using the validated Portuguese versions of the SF-36 and OHIP-49 questionnaires. Methods A calculated sample of Brazilian patients with BMS (n = 26 was compared with a control group (n = 27, paired for gender and age. Sociodemographic information and clinical characteristics were obtained, and interviews were conducted using the SF-36 and OHIP-49. To evaluate the normality of the variables, we used the Kolmogorov-Smirnov test. The chi-square test, Fisher exact test and Mann-Whitney U-Test were used to compare sociodemographic and clinical characteristics of individuals with BMS and controls Mann-Whitney U-test were carried out to compare SF-36 and OHIP-49 between BMS patients and controls. The significance level was set at 0.05. To compare the dimensions of the SF-36 and OHIP-49 between BMS patients and controls, we considered Bonferroni correction. So for comparison of the dimensions, the significance level was set at 0.00625 for SF-36 and at 0.00714 for OHIP-49. Results The clinical and demographic data were similar in both groups (P > 0.05. SF-36 scores were significantly lower in all domains for patients with BMS (P Conclusions BMS has a negative impact on the health-related quality of life of individuals, as can be shown by instruments such as the SF-36 and OHIP-49. So, the evaluation of quality of life might be useful for more information about the nature and severity of BMS, to evaluate the effects of treatment protocols, in order to improve their outcomes by means a humanized clinical practice.

Self-reported health measures are important indicators used by clinicians and researchers for the evaluation of health interventions, outcome assessment of clinical studies, and identification of health needs to improve resource allocation. However, the application of self-reported health measures relies on developing reliable and valid instruments that are suitable across diverse populations. The main objective of this study is to evaluate the construct validity of the SF-12v.2, an instrument for measuring self-rated physical and mental health, for homeless adults with mental illness. Various interventions have been aimed at improving the health of homeless people with mental illness, and the development of valid instruments to evaluate these interventions is imperative. We measured self-rated mental and physical health from a quota sample of 575 homeless people with mental illness using the SF-12v2, EQ-5D, Colorado Symptoms Index, and physical/mental health visual analogue scales. We examined the construct validity of the SF-12v2 through confirmatory factor analyses (CFA), and using ANOVA/correlation analyses to compare the SF-12v2 to the other instruments to ascertain discriminant/convergent validity. Our CFA showed that the measurement properties of the original SF-12v2 model had a mediocre fit with our empirical data (χ2 = 193.6, df = 43, p physical and mental health status for a homeless population with mental illness.

The psychometric properties of generic health-related quality of life (HRQOL) assessment instruments were evaluated to identify a reliable, valid, and non-redundant battery to measure longitudinal outcomes in organ transplant patients. Objective functional performance and subjective HRQOL were assessed in 371 solid organ (liver, heart, kidney, lung) transplant patients using the Karnofsky scale, the SF-36 Health Survey (SF-36), and Psychosocial Adjustment to Illness Scale (PAIS). The surveys' internal-consistency reliability, criterion-related validity, and redundancy were tested. The SF-36 mental (MCS) and physical components (PCS), and PAIS summary scales were internally consistent (all alpha > or = 0.83). Four out of seven PAIS scales (vocational, domestic, sexual, social) were collectively associated with the PCS (R = 0.65, P satisfaction) scale was not associated with the SF-36((R)). The relationship between functional performance and the PCS is stronger (r = 0.52, P global score (r = 0.37, P satisfaction inventory was indicated and was developed.

Rethinking ASGISA and the rand exchange rate

Directory of Open Access Journals (Sweden)

Willem H Boshoff

2012-05-01

Full Text Available Abstract: The ASGISA policy document identifies the exchange rate as one of the factors constraining accelerated growth in South Africa. This note argues that currency developments do not translate into business cycle movements in the aggregate economy, and that a weaker exchange rate is less likely to boost either foreign investment or export performance in the face of regulatory uncertainty. The South African government has recently launched the Accelerated and Shared Growth Initiative (ASGISA aimed at raising the long-term growth path of the economy. The plan identifies several so-called “binding constraints” that are considered to be inhibiting the economy from rising to more elevated levels of economic growth. One such “constraint”, according to the ASGISA policy document, is the “volatility and level of the currency” (Republic of South Africa, 2006. By including this issue, policymakers have signalled that fluctuations in the Rand are considered significant to broader economic fluctuations in South Africa. This research note questions such a conviction by offering evidence that currency fluctuations are not mirrored in the South African business cycle. Nonetheless, proponents may argue that a weaker Rand will stimulate particular sectors, mostly those that are export-oriented, while it will boost Foreign Direct Investment (FDI. However, this note argues further that a weaker Rand is less likely to generate sustainable improvement in either export-oriented industries or FDI in the absence of other reforms. The following sections consider these two issues in sequence.

This paper investigates the properties and performance of the two generic measures, EQ-5D and SF-12, for Health-Related Quality of Life (HRQoL) assessments of pregnant women living with HIV in Kunming City, Yiliang County, Daguan County, Longchuan County, Tengchong County, Longling County and Fengqing County in Yunnan Province, China. As part of a screening programme for the prevention of mother-to-child transmission of HIV (PMTCT), a retrospective cross-sectional survey was conducted in the seven Maternal and Infant Health Care centers in Yunnan Province, China, between April and June of 2016. The demographic and HIV infection-related information used in the study was collected through questionnaires designed by the study's staff. HRQoL information was collected using two generic scales: EQ-5D and SF-12. A total sample of one hundred and one pregnant women with a mean age of 30.4 ± 5.1 years was investigated. Average time elapsed since infection diagnoses was 5.8 ± 3.4 years. Only one infant (1.0%) was HIV positive, and 56 (55.4%) infants were HIV negative. The HIV status of 44 (43.6%) infants was unknown. The relationship between the EQ-5D functional dimensions and the PCS-12 and the relationship between the EQ-5D anxiety/depression dimension and the MCS-12 were stronger. Those whose PCS-12 and MCS-12 scores were at the median or lower were classified as being in worse health, while those over the median were classified as being in better health. Respondents who reported no problem on each of the EQ-5D dimensions was divided according to the median SF-12 component scores. Those who scored at the median or lower than the median were classified as being in worse health, while those higher than the median were classified as being in better health. The VAS scores were also significantly different than the median split of the SF-12 scores for these subjects. EQ-5D and SF-12 showed a discrimination ability in measuring the HRQoL of pregnant women living with

Trismus is a common symptom often related to the treatment for head and neck cancer and to temporomandibular disorders. The purpose of the present study was to measure the impact of trismus on health-related quality of life (HRQOL) and mental health in patients with head and neck cancer and temporomandibular disorder. We used the criteria for trismus of maximum interincisal opening (MIO) ≤35 mm and the study subjects responded to the following instruments: the Gothenburg Trismus Questionnaire (GTQ), the Short-Form 36 Health Survey (SF-36), and the Hospital Anxiety and Depression Scale (HADS). The study also comprised an age-matched and sex-matched control group without trismus. Patients with trismus reported significantly more dysfunction in all GTQ domains and more facial pain compared to the control group. The patients with head and neck cancer and trismus scored significantly lower on all SF-36 domains except general health compared to the control group, and the patients with temporomandibular disorder with trismus scored significantly lower in 3 of the 8 domains in SF-36. According to the HADS, a greater proportion of patients with head and neck cancer with trismus displayed more depression compared to the control group. The results showed that trismus is associated with a significant impact on HRQOL and that patients with trismus should be approached in a holistic way with respect for the underlying cause, treating not only the physical aspects of trismus but also addressing the patients' mental health. © 2014 Wiley Periodicals, Inc.

Despite a perception that retired professional football players have poor health, there are little supporting data. Retired football players have poor health compared with age-matched population norms. Cross-sectional study; Level of evidence, 4. Thirty-six of 41 members of the 1969 Super Bowl winning team were contacted 35 years after that event (3 were deceased, and no contact information was available for 2). Players completed an SF-36 health survey and a medical history and football-specific questionnaire. Each player's football-related injury history before 1969 was documented from medical records. It was estimated that there was 80% power to detect a 10% difference in physical and mental health scores between the retired football players (age, 62 +/- 3 y) and population norms (n = 741) at an alpha level of 0.05. SF-36 scores for physical and mental health were not different from age-matched norms (physical health P = .69; mental health P = .49). The most prevalent medical conditions were arthritis (24 of 36 players), hypertension (13 of 36 players), and chronic low back pain (13 of 36 players). SF-36 physical health scores were 21% lower in players with arthritis (P football for 8.3 +/- 3.8 years, and 33 players (94%) reported having had "very fulfilling" (n = 24) or "somewhat fulfilling" (n = 9) careers. These professional football players had long and fulfilling careers with no apparent long-term detrimental effects on physical or mental health scores despite a high prevalence of arthritis.

Archaea microorganisms have long been used as model organisms for the study of protein molecular machines. Archaeal proteins are particularly appealing to study since archaea, even though prokaryotic, possess eukaryotic-like cellular processes. Super Family I (SF1) and Super Family II (SF2) helicase families have been studied in many model organisms, little is known about their presence and distribution in archaea. We performed an exhaustive search of homologs of SF1 and SF2 helicase proteins in 95 complete archaeal genomes. In the present study, we identified the complete sets of SF1 and SF2 helicases in archaea. Comparative analysis between archaea, human and the bacteria E. coli SF1 and SF2 helicases, resulted in the identification of seven helicase families conserved among representatives of the domains of life. This analysis suggests that these helicase families are highly conserved throughout evolution. We highlight the conserved motifs of each family and characteristic domains of the detected families. Distribution of SF1/SF2 families show that Ski2-like, Lhr, Sfth and Rad3-like helicases are ubiquitous among archaeal genomes while the other families are specific to certain archaeal groups. We also report the presence of a novel SF2 helicase specific to archaea domain named Archaea Specific Helicase (ASH). Phylogenetic analysis indicated that ASH has evolved in Euryarchaeota and is evolutionary related to the Ski2-like family with specific characteristic domains. Our study provides the first exhaustive analysis of SF1 and SF2 helicases from archaea. It expands the variety of SF1 and SF2 archaeal helicases known to exist to date and provides a starting point for new biochemical and genetic studies needed to validate their biological functions.

Progressive deterioration in patients with amyotrophic lateral sclerosis (ALS) has a major impact on their health-related quality of life (HRQOL). The objectives of this study are to evaluate HRQOL in a sample of patients diagnosed with ALS and estimate the predictive capability of a set of sociodemographic variables for the different scales covered by a general health survey. A total of 63 patients diagnosed with ALS were assessed using a sociodemographic questionnaire and the SF-36 general health survey. The sociodemographic variables studied were sex, age, presence of a caregiver, employment status, and time from diagnosis of disease. The SF-36 survey shows positive correlations between the different scales composing it, which proves its reliability. The mean scores obtained for each of the SF-36 scales were higher in men than in women, although the only statistically significant difference was for the Physical Role scale. The lowest age range (less than 56 years) presented the highest mean scores for most of these dimensions. Most of the variance in the test is explained by the variable 'presence of caregiver'. The SF-36 health survey has been confirmed as a valid and useful tool for evaluating HRQOL in ALS patients, and it discriminates between patients in different states of health according to their level of dependency.

In response to concerns that the Department of Veterans Affairs (VA) has faced about veterans' access to care and the quality of care delivered, Congress enacted the Veterans Access, Choice, and Accountability Act of 2014 ("Veterans Choice Act") in August 2014. The law was passed to help address access issues by expanding the criteria through which veterans can seek care from civilian providers. In addition, the law called for a series of independent assessments of the VA health care system across a broad array of topics related to the delivery of health care services to veterans in VA-owned and -operated facilities, as well as those under contract to VA. RAND conducted three of these assessments: Veteran demographics and health care needs (A), VA health care capabilities (B), and VA authorities and mechanisms for purchasing care (C). This article summarizes the findings of our assessments and includes recommendations from the reports for improving the match between veterans' needs and VA's capabilities, including VA's ability to purchase necessary care from the private sector.

To describe indicators of job dissatisfaction among amputee employees and to compare job satisfaction and health experience of working amputee employees with that of control subjects. A cross-sectional study, mailed questionnaire. Patients were recruited by the orthopedic workshops of the Netherlands. One hundred forty-four patients who had an acquired unilateral major amputation of the lower limb at least 2 years before, were aged 18 to 60 years (mean age, 43y), and were living and working in the Netherlands. One hundred forty-four control subjects matched for age, gender, and type of job. Not applicable. Statistical analysis of responses to a questionnaire regarding patient characteristics and amputation-related factors, amputee patients' opinions about their work and the social atmosphere at work, and their general health (RAND 36-Item Health Survey [RAND-36]). People with an amputation had greater job satisfaction (70%) than did the able-bodied control group (54%). The wish for (better) modifications in the workplace and the presence of comorbidity were significantly related to job dissatisfaction in people with limb loss. Amputee employees were less often hindered by the failures of others and by fluctuations in temperature. People with limb loss showed a worse physical health experience than controls on the RAND-36. The vocational satisfaction of people with limb loss may be improved by better workplace modifications, depending on the functional capabilities of the person and the functional demands of the job; improvement may also be achieved by vocational rehabilitation programs, especially for those with an amputation in combination with other morbidity. Despite experiencing more health problems, the amputee group expressed greater job satisfaction than the able-bodied group, reflecting a great appreciation of job reintegration by people with a lower-limb amputation.

Integrative strategy of health services delivery has been proven to be effective in economically developed countries, where the healthcare systems have enough qualified primary care providers. However rural China lacks such providers to act as gatekeeper, besides, Chinese rural hypertensive patients are usually of old age, more likely to be exposed to health risk factors and they experience a greater socio-economic burden. All these Chinese rural setting specific features make the effectiveness of integrative strategy of health services in improving health related quality of life among Chinese rural hypertensive patients uncertain. In order to assess the impact of integrative strategy of health services delivery on health related quality of life among Chinese rural hypertensive patients, a two-year quasi-experimental trial was conducted in Chongqing, China. At baseline the sample enrolled 1006 hypertensive patients into intervention group and 420 hypertensive patients into control group. Physicians from village clinics, town hospitals and county hospitals worked collaboratively to deliver multidisciplinary health services for the intervention group, while physicians in the control group provided services without cooperation. The quality of life was studied by SF-36 Scale. Blood pressures were reported by town hospitals. The Difference-in-Differences model was used to estimate the differences in SF-36 score and blood pressure of both groups to assess the impact. The study showed that at baseline there was no statistical difference in SF-36 scores between both groups. While at follow-up the intervention group scored higher in overall SF-36, Role Physical, Body Pain, Social Functioning and Role Emotional than the control group. The Difference-in-Differences result demonstrated that there were statistical differences in SF-36 total score (p = 0.011), Role Physical (p = 0.027), Social Functioning (p = 0.000), Role Emotional (p = 0.002) between both

This paper explores the concept of health implied in the SF-36 within a group of Iranians in Australia. Qualitative data were collected from a sample of 21 people--10 females and 11 males. For the first time, the NUD*IST program was used to organize and manage the data in Persian (also known as Farsi), the language spoken by Iranians. Health was defined in terms of holistic, spiritual, social, physical/emotional aspects, and absence-of-disorder dimensions. Among these, physical, absence of disorder, holistic, and spiritual aspects of health were mentioned more frequently than other themes. The findings of the study raise concerns about the extent to which the SF-36 captures the diversity of the concept of health as expressed by the sample of Iranian migrants.

Rigorously applied exercise interventions undertaken in a research setting result in improved health-related quality of life (hrqol) in cancer survivors, but research to demonstrate effective translation of that research to practice is needed. The objective of the present study was to determine the effect of fee-for-service cancer rehabilitation programs in the community on hrqol and on self-reported physical activity and its correlates. After enrolment and 17 ± 4 weeks later, new clients (n = 48) to two fee-for-service cancer rehabilitation programs completed the 36-Item Short Form Health Survey (rand-36: rand Corporation, Santa Monica, CA, U.S.A.), the Godin Leisure-Time Exercise Questionnaire, and questions about physical activity correlates. Normal fee-for-service operations were maintained, including a fitness assessment and individualized exercise programs supervised in a group or one-on-one setting, with no minimum attendance required. Fees were associated with the assessment and with each exercise session. Of the 48 participants, 36 (75%) completed both questionnaires. Improvements in the physical functioning, role physical, pain, and energy/fatigue scales on the rand-36 exceeded minimally important differences and were of a magnitude similar to improvements reported in structured, rigorously applied, and free research interventions. Self-reported levels of vigorous-intensity (p = 0.021), but not moderate-intensity (p = 0.831) physical activity increased. The number of perceived barriers to exercise (p = 0.035) and the prevalence of fatigue as a barrier (p = 0.003) decreased. Exercise self-efficacy improved only in participants who attended 11 or more sessions (p = 0.002). Exercise enjoyment did not change (p = 0.629). Enrolment in fee-for-service cancer rehabilitation programs results in meaningful improvements in hrqol comparable to those reported by research interventions, among other benefits. The fee-for-service model could be an effective model for

Health-related quality of life (HRQOL) measures have become the mainstay for outcome appraisal in spine surgery. Clinically meaningful interpretation of HRQOL improvement has centered on the minimum clinically important difference (MCID). The purpose of this study was to calculate clinically important deterioration (CIDET) thresholds and determine a CIDET value for each HRQOL measure for patients undergoing lumbar fusion. Seven hundred twenty-two patients (248 males, 127 smokers, mean age 60.8 years) were identified with complete preoperative and 1-year postoperative HRQOLs including the Oswestry Disability Index (ODI), 36-Item Short Form Health Survey (SF-36), and numeric rating scales (0-10) for back and leg pain following primary, instrumented, posterior lumbar fusion. Anchor-based and distribution-based methods were used to calculate CIDET for each HRQOL. Anchor-based methods included change score, change difference, and receiver operating characteristic curve analysis. The Health Transition Item, an independent item of the SF-36, was used as the external anchor. Patients who responded "somewhat worse" and "much worse" were combined and compared with patients responding "about the same." Distribution-based methods were minimum detectable change and effect size. Diagnoses included spondylolisthesis (n = 332), scoliosis (n = 54), instability (n = 37), disc pathology (n = 146), and stenosis (n = 153). There was a statistically significant change (p < 0.0001) for each HRQOL measure from preoperatively to 1-year postoperatively. Only 107 patients (15%) reported being "somewhat worse" (n = 81) or "much worse" (n = 26). Calculation methods yielded a range of CIDET values for ODI (0.17-9.06), SF-36 physical component summary (-0.32 to 4.43), back pain (0.02-1.50), and leg pain (0.02-1.50). A threshold for clinical deterioration was difficult to identify. This may be due to the small number of patients reporting being worse after surgery and the variability across

To compare the health-related quality of life (HRQOL) and the functional ability by race in patients with gout. In a 9-month prospective cohort multicentre study, patients with gout self-reported race, dichotomized as Caucasian or African American (others excluded). We calculated HRQOL/function scores adjusted for age, study site and college education for Short Form-36 (SF-36; generic HRQOL), Gout Impact Scale (GIS; disease-specific HRQOL) and HAQ-disability index (HAQ-DI; functional ability). Longitudinally adjusted scores were computed using multivariable mixed-effect regression models with a random patient effect and fixed sequential visit effect (3-monthly visits). Compared with Caucasians (n = 107), African Americans (n = 60) with gout were younger (61.1 vs 67.3 years) and had higher median baseline serum urate (9.0 vs 7.9 mg/dl) (P gout had worse HRQOL scores on three SF-36 domains, the mental component summary (MCS) and two of the five GIS scales than Caucasians [mean (se); P ⩽ 0.02 for all]: SF-36 mental health, 39.7 (1.1) vs 45.2 (0.9); SF-36 role emotional, 42.1 (4.2) vs 51.4 (4.2); SF-36 social functioning, 36.0 (1.1) vs 40.0 (0.9) (P = 0.04); SF-36 MCS, 43.2 (3.1) vs 50.0 (3.2); GIS unmet treatment need, 37.6 (1.6) vs 31.5 (1.4); and GIS concern during attacks, 53.3 (3.7) vs 47.4 (3.7). Differences between the respective HAQ-DI total scores were not statistically significant; 0.98 (0.1) vs 0.80 (1.0) (P = 0.11). Racial differences in SF-36 mental health, role emotional and MCS scales exceeded, and for HAQ-DI approached, the minimal clinically important difference thresholds. African Americans with gout have significantly worse HRQOL compared with Caucasians. Further research is necessary in the form of studies targeted at African Americans on how best to improve these outcomes.

We have calculated α and eta, the ionization and attachment coefficients, and (E/N) *, the limiting breakdown electric-field--to--gas-density ratio, in SF 6 and SF 6 mixtures by numerically solving the Boltzmann equation for the electron energy distribution. The calculations require a knowledge of several electron collision cross sections. Published momentum transfer and ionization cross sections for SF 6 were used. We measured various attachment cross sections for SF 6 using electron-beam techniques with mass spectrometric ion detection. We determined a total cross section for electronic excitation of SF 6 by comparing the predicted values of α, eta, and (E/N) * with our measured values obtained from spatial current growth experiments in SF 6 in uniform fields over an extended range of E/N. With this self-consistent set of SF 6 cross sections, together with published He and N 2 cross sections, it was then possible to predict the dielectric properties of SF 6 -He and SF 6 -N 2 mixtures. Published experimental values of α for the SF 6 -He mixtures lie between the values of α calculated with and without ionization of SF 6 by excited He atoms. Published experimental values of (E/N) * agree with our calculations to within 5% in both the SF 6 -He and the SF 6 -N 2 mixtures

Yaw-Wen Chang

Full Text Available BACKGROUND: The purpose of this study was to identify the incidence of frailty and to investigate the relationship between frailty status and health-related quality of life (HRQoL in the community-dwelling elderly population who utilize preventive health services. METHODS: People aged 65 years and older who visited a medical center in Taipei City from March to August in 2011 for an annual routine check-up provided by the National Health Insurance were eligible. A total of 374 eligible elderly adults without cognitive impairment had a mean age of 74.6±6.3 years. Frailty status was determined according to the Fried frailty criteria. HRQoL was measured with Short Form-36 (SF-36. Multiple regression analyses examined the relationship between frailty status and the two summary scales of SF-36. Models were adjusted for the participants' sociodemographic and health status. RESULTS: After adjusting for sociodemographic and health-related covariables, frailty was found to be more significantly associated (p<0.001 with lower scores on both physical and mental health-related quality of life summary scales compared with robustness. For the frailty phenotypes, slowness represented the major contributing factor in the physical component scale of SF-36, and exhaustion was the primary contributing factor in the mental component scale. CONCLUSION: The status of frailty is closely associated with HRQoL in elderly Taiwanese preventive health service users. The impacts of frailty phenotypes on physical and mental aspects of HRQoL differ.

The "11K" gene family members sf68, sf95 and sf138 modulate transmissibility and insecticidal properties of Spodoptera frugiperda multiple nucleopolyhedrovirus.

The "11K" gene family is notable for having homologs in both baculoviruses and entomopoxviruses and is classified as either type 145 or type 150, according to their similarity with the ac145 or ac150 genes of Autographa californica multiple nucleopolyhedrovirus (AcMNPV). One homolog of ac145 (sf138) and two homologs of ac150 (sf68 and sf95) are present in Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV). Recombinant bacmids lacking sf68, sf95 or sf138 (Sf68null, Sf95null and Sf138null, respectively) and the respective repair bacmids were generated from a bacmid comprising the complete virus genome. Occlusion bodies (OBs) of the Sf138null virus were ∼15-fold less orally infective to insects, which was attributed to a 100-fold reduction in ODV infectious titer. Inoculation of insects with Sf138null OBs in mixtures with an optical brightener failed to restore the pathogenicity of Sf138null OBs to that of the parental virus, indicating that the effects of sf138 deletion on OB pathogenicity were unlikely to involve an interaction with the gut peritrophic matrix. In contrast, deletion of sf68 and sf95 resulted in a slower speed-of-kill by 9h, and a concurrent increase in the yield of OBs. Phylogenetic analysis indicated that sf68 and sf95 were not generated after a duplication event of an ancestral gene homologous to the ac150 gene. We conclude that type 145 genes modulate the primary infection process of the virus, whereas type 150 genes appear to have a role in spreading systemic infection within the insect.

Unchained Melody: Revisiting the Estimation of SF-6D Values

Craig, Benjamin M.

2015-01-01

Purpose In the original SF-6D valuation study, the analytical design inherited conventions that detrimentally affected its ability to predict values on a quality-adjusted life year (QALY) scale. Our objective is to estimate UK values for SF-6D states using the original data and multi-attribute utility (MAU) regression after addressing its limitations and to compare the revised SF-6D and EQ-5D value predictions. Methods Using the unaltered data (611 respondents, 3503 SG responses), the parameters of the original MAU model were re-estimated under 3 alternative error specifications, known as the instant, episodic, and angular random utility models. Value predictions on a QALY scale were compared to EQ-5D3L predictions using the 1996 Health Survey for England. Results Contrary to the original results, the revised SF-6D value predictions range below 0 QALYs (i.e., worse than death) and agree largely with EQ-5D predictions after adjusting for scale. Although a QALY is defined as a year in optimal health, the SF-6D sets a higher standard for optimal health than the EQ-5D-3L; therefore, it has larger units on a QALY scale by construction (20.9% more). Conclusions Much of the debate in health valuation has focused on differences between preference elicitation tasks, sampling, and instruments. After correcting errant econometric practices and adjusting for differences in QALY scale between the EQ-5D and SF-6D values, the revised predictions demonstrate convergent validity, making them more suitable for UK economic evaluations compared to original estimates.

Mitochondrial disorders belong to the most prevalent inherited metabolic diseases with the m.3243A > G mutation reflecting being one of the most common mutations in mitochondrial DNA. Previous studies showed little relationship between mitochondrial genetics and disease manifestation. Relationship between genotype and disease manifestation with patient reported quality of life and other patient reported outcomes is still unexplored. Seventy-two out of the 122 invited adult patients with m.3243A > G mutation completed online standardized questionnaires on quality of life, functional impairment, fatigue and mental health as assessed by the RAND-SF36, the Sickness Impact Profile (SIP), the Checklist Individual Strength (CIS) and the Hospital Anxiety and Depression scale (HADS). Data were related to clinical manifestation reflected by the Newcastle Mitochondrial Disease Adult Scale (NMDAS) score and heteroplasmy levels of the mutation in urine epithelial cells. Patients reported impaired quality of life. Sixty percent showed severe levels of fatigue, and 37% showed clinical relevant mental health problems, which was significantly more than healthy norms. These patient reported health outcomes showed negligible relationship with levels of heteroplasmy (r = mental health problems, are only partly reflected by clinical assessments. In order to support patients more effectively, integration of patient reported outcomes, alongside symptoms of their disease, in clinical practice is warranted.

To investigate how SF-6D utility scores change with age between generations of women and to quantify the relationship of SF-6D with lifestyle factors across life stages. Up to seven waves of self-reported, longitudinal data were drawn for the 1973-1978 (young, N = 13772), 1946-1951 (mid-age, N = 12792), 1921-1926 (older, N = 9972) cohorts from the Australian Longitudinal Study on Women's Health. Mixed effects models were employed for analysis. Young and mid-age women had similar average SF-6D scores at baseline (0.63-0.64), which remained consistent over the 16-year period. However, older women had lower scores at baseline at 0.57 which steadily declined over 15 years. Across cohorts, low education attainment, greater difficulty in managing income, obesity, physical inactivity, heavy smoking, no alcohol consumption, and increasing stress levels were associated with lower SF-6D scores. The magnitude of effect varied between cohorts. SF-6D scores were lower amongst young women with high-risk drinking behaviours than low-risk drinkers. Mid-age women, who were underweight, never married, or underwent surgical menopause also reported lower SF-6D scores. Older women who lived in remote areas, who were ex-smokers, or were underweight, reported lower SF-6D scores. The SF-6D utility score is sensitive to differences in lifestyle factors across adult life stages. Gradual loss of physical functioning may explain the steady decline in health for older women. Key factors associated with SF-6D include physical activity, body mass index, menopause status, smoking, alcohol use, and stress. Factors associated with poorer SF-6D scores vary in type and magnitude at different life stages.

Fibromyalgia is a painful syndrome characterized by widespread chronic pain and associated symptoms with a negative impact on quality of life. Considering the subjectivity of quality of life measurements, the aim of this study was to verify the discriminating power of two quality of life questionnaires in patients with fibromyalgia: the generic Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the specific Fibromyalgia Impact Questionnaire (FIQ). A cross-sectional study was conducted on 150 participants divided into Fibromyalgia Group (FG) and Control Group (CG) (n=75 in each group). The participants were evaluated using the SF-36 and the FIQ. The data were analyzed by the Student t-test (α=0.05) and inferential analysis using the Receiver Operating Characteristics (ROC) Curve--sensitivity, specificity and area under the curve (AUC). The significance level was 0.05. The sample was similar for age (CG: 47.8 ± 8.1; FG: 47.0 ± 7.7 years). A significant difference was observed in quality of life assessment in all aspects of both questionnaires (pquality of life in fibromyalgia patients, and we suggest that both should be used in parallel because they evaluate relevant and complementary aspects of quality of life.

Dielectric properties for SF6 and SF6 mixtures predicted from basic data

International Nuclear Information System (INIS)

Kline, L.E.; Davies, D.K.; Chen, C.L.; Chantry, P.J.

1978-01-01

α and eta, the ionization and attachment coefficients, and (E/N)*, the limiting breakdown electric field-to-gas density ratio, in SF 6 and SF 6 mixtures were calculated by numerically solving the Boltzmann equation for the electron energy distribution. The calculations require a knowledge of several electron collision cross sections. Published momentum transfer and ionization cross sections for SF 6 were used. Various attachment cross sections for SF 6 were measured by using electron beam techniques with mass spectrometric ion detection. A total cross section for electronic excitation of SF 6 was determined by comparing the predicted values of α, eta, and (E/N)* with measured values obtained from spatial current growth experiments in SF 6 in uniform fields over an extended range of E/N. With this self-consistent set of SF 6 cross sections, together with published He cross sections, it was then possible to predict the dielectric properties of SF 6 --He mixtures. Published experimental values of α for these mixtures lie between the values of α calculated with and without ionization of SF 6 by excited He atoms. Published experimental values of (E/N)* agree with the calculations to within 5%. 11 figures

Sarcoidosis is a chronic disease with different phenotypic manifestations. Health-related quality of life is an important aspect in sarcoidosis, yet difficult to measure. The objective of this study was to identify clinical markers predictive of poor quality of life in sarcoidosis patients that can be followed over time and targeted for intervention. We assessed the quality of life of 162 patients with confirmed sarcoidosis in a prospective, cross-sectional study using the Sarcoidosis Health Questionnaire (SHQ) and Short Form-36 Health Survey (SF-36). We evaluated the validity of these questionnaires and sought to identify variables that would best explain the performance scores of the patients. On multivariate regression analyses, the very best composite model to predict total scores from both surveys was a model containing the distance-saturation product and Borg Dyspnea Scale score at the end of a 6-min walk test. This model could better predict SF-36 scores (R² = 0.33) than SHQ scores (R² = 0.24). Substitution of distanced walked in 6 min for the distance-saturation product in this model resulted in a lesser ability to predict both scores (R² = 0.26 for SF-36; R² = 0.22 for SHQ). Both the SHQ and SF-36 surveys are valuable tools in the assessment of health-related quality of life in sarcoidosis patients. The best model to predict quality of life among these patients, as determined by regression analyses, included the distance-saturation product and Borg score after the 6-min walk test. Both variables represent easily obtainable clinical parameters that can be followed over time and targeted for intervention.

Being born with very low birth weight (VLBW: ≤ 1,500 g) is related to long-term disability and neurodevelopmental problems, possibly affecting mental health and health-related quality of life (HRQoL). However, studies in young adulthood yield mixed findings. The aim of this study was to examine mental health and HRQoL at 23 years, including changes from 20 to 23 years and associations with motor skills in VLBW young adults compared with controls. In a geographically based follow-up study, 35 VLBW and 37 term-born young adults were assessed at 23 years by using Achenbach Adult Self-Report (ASR), Short Form 36 Health Survey (SF-36), Beck Depression Inventory (BDI) and various motor tests. The ASR and SF-36 were also used at 20 years. Longitudinal changes in ASR and SF-36 from 20 to 23 years were analysed by linear mixed models and associations with motor skills at 23 years by linear regression. At 23 years, total ASR score was 38.6 (SD: 21.7) in the VLBW group compared with 29.0 (SD: 18.6) in the control group (p = 0.048). VLBW participants had higher scores for attention problems, internalizing problems and critical items, and they reported to drink less alcohol than controls. BDI total score did not differ between groups. On SF-36, VLBW participants reported significantly poorer physical and social functioning, more role-limitations due to physical and emotional problems, more bodily pain and lower physical and mental component summaries than controls. In the VLBW group, total ASR score increased by 9.0 (95 % CI: 3.3 to 14.7) points from 20 to 23 years (p = 0.009 vs controls), physical and mental component summaries of SF-36 decreased by 2.9 (95 % CI: -4.8 to -1.1) and 4.4 (95 % CI: -7.1 to -1.7) points, respectively (p = 0.012 and p = 0.022 vs controls). Among VLBW participants, more mental health problems and lower physical and mental HRQoL were associated with poorer motor skills at 23 years. VLBW young adults reported poorer and declining

The SF-12v2 is the improved version of the SF-12v1. This study aimed to validate the SF-12v2 in Iran. A random sample of the general population aged 18 years and over living in Tehran, Iran completed the instrument. Reliability was estimated using internal consistency and validity was assessed using known-groups comparison and convergent validity. In addition the factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses (EFA and CFA). In all, 3685 individuals were studied (1887 male and 1798 female). Internal consistency for both summary measures was satisfactory. Cronbach's α for the Physical Component Summary (PCS-12) was 0.87 and for the Mental Component Summary (MCS-12) it was 0.82. Known-groups comparison showed that the SF-12v2 discriminated well between men and women and those who differed in age and educational status (P < 0.05). Furthermore, as hypothesized the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12, while the vitality, social functioning, role emotional and mental health subscales correlated higher with the MCS-12. Finally the exploratory factor analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 59.9% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). Although the findings could not be generalized to the Iranian population, overall the findings suggest that the SF-12v2 is a reliable and valid measure of health related quality of life among Iranians and now could be used in future health outcome studies. However, further studies are recommended to establish its stability, responsiveness to change, and concurrent validity for this health survey in Iran.

Organizing complexity: the hopeful dreams and harsh realities of interdisciplinary collaboration at the rand corporation in the early cold war.

Science.gov (United States)

Bessner, Daniel

Historians argue that in the early Cold War an interdisciplinary research culture defined the RAND Corporation. However, a significant epistemological gap divided the members of RAND's Social Science Division (SSD) from the rest of the organization. While the social scientists used qualitative methods, most RAND researchers embraced quantified approaches and derided the social sciences as unscientific. This encouraged RAND's social scientists to develop a political-military simulation that embraced everything-politics, culture, and psychology-that RAND's other analysts largely ignored. Yet the fact that the SSD embraced gaming, a heuristic practiced throughout RAND, suggests that the political simulation was nonetheless inspired by social scientists' engagement with their colleagues. This indicates that the concept of interdisciplinarity should move beyond its implication of collaboration to incorporate instances in which research agendas are defined against but also shaped by colleagues in other disciplines. Such a rethinking of the term may make it possible to trace how varieties of interdisciplinary interaction historically informed knowledge production. © 2014 Wiley Periodicals, Inc.

• BACKGROUND: The aim of this study was to investigate the association between the two most commonly used generic and disease specific health-related quality of life (HRQoL measures in patients with chronic lung disease due to SM: Medical Outcomes Study Short Form 36-Item (SF-36 and St George's Respiratory Questionnaire (SGRQ.
• METHODS: This is a secondary analysis of Iranian Chemical Warfare Victims Health Assessment Study (ICWVHAS during October 2007 in Isfahan, Iran. In that survey, conducted in an outpatient setting, 292 patients with chronic lung disease due to SM were selected from all provinces in Iran. The total score and sub scores of correlations of SGRQ and SF-36 were assessed. Correlation of quality-of-life scores were evaluated using Pearson’s coefficient.
• RESULTS: Samples were 276 patients who were selected for our analysis. No significant correlation was found between the total score or sub scores of SF-36 and the total score or sub scores of SGRQ (p > 0.05.
• CONCLUSIONS: In patients with chronic lung disease due to SM, the SF-36 and SGRQ assess different aspects of HRQoL. Therefore applying both of them together, at least in the research setting is suggested.

Full Text Available Abstract Background Diabetes mellitus (DM is an important public health concern, the impact of which is increased by the high prevalence of co-existing chronic medical conditions among subjects with DM. The aims of this study were therefore to (1 evaluate the impact of DM and co-existing chronic medical conditions on health-related quality of life (HRQoL (which could be additive, synergistic or subtractive; (2 to determine the extent to which the SF-6D (a single-index preference measure captures the multidimensional information provided by the SF-36 (a profile measure. Methods Using data from a cross-sectional, population-based survey of Chinese, Malay and Indians in Singapore, we developed 9 separate multiple linear regression models, with each SF-36 scale or SF-6D index score being the dependent variable for one model. The influence of DM and a second chronic medical condition (hypertension (HTN, heart disease (HD, musculoskeletal illnesses (MS and their interactions were studied after adjusting for the influence of potential confounding variables. Results Among 5,224 subjects, the prevalence of DM, HTN, HD and MS were 5.9%, 10.7%, 2.4% and 26.6% respectively. DM lowered SF-36 scores by more than 2 points on 3 SF-36 scales and lowered SF-6D scores by 0.03 points. Subjects with DM and HTN, DM and HD or DM and MS experienced further lowering of SF-36 scores exceeding 2 points on at least 6 scales and further lowering of SF-6D scores by 0.05, 0.08 and 0.10 points respectively. Generally, DM and co-existing medical conditions exerted additive effects on HRQoL, with the exception of DM and heart disease, where a subtractive effect was noted. SF-6D index scores generally reflected the patterns of influence of DM and chronic medical conditions on SF-36 scores. Conclusion DM and chronic medical conditions generally reduced HRQoL in this multiethnic general population in an additive, rather than synergistic or subtractive fashion. In this study, the SF

The purpose of this study was to examine the sleep quality and health-related quality of life (HRQOL) in patients after renal transplantation and to explore the relationship between the quality of sleep and the HRQOL. Sleep disorders are still an important clinical problem after renal transplantation. Previous studies mainly focused on patients' sleep quality before kidney transplant. More studies are needed to document sleep quality after renal transplantation. A cross-sectional design was used in this study. A convenience sample of renal transplant recipients was recruited at an outpatient transplant clinic of a general hospital in Beijing, China. The Pittsburgh Sleep Quality Index (PSQI) was used to measure quality of sleep. The Medical Outcomes Study 36-item Short Form (MOS SF-36) was used to measure health-related quality of life. The average PSQI score of the 204 renal transplant recipients was 5.81±3.52, significantly lower than the norm. Fifty (24.5%) recipients were classified as having poor sleep quality (global PSQI > 7). The mean scores of renal transplant recipients for SF-36 Mental Component Summary (MCS) and Physical Component Summary (PCS) were 47.57±6.71 and 48.26±9.66 respectively. Compared with residents in Sichuan province, recipients' scores for SF-36 dimensions were statistically lower except the dimension of mental health. SF-36 scores of poor sleepers (PSQI > 7) were significantly lower than the good sleepers (PSQI ≤ 7) in both the MCS and PCS. Significant differences exist between the groups in physical function, bodily pain, vitality, and mental health dimensions. Sleep quality and HRQOL of patients after renal transplantation were lower than the norm. Poor sleep is associated with lower HRQOL. Health professionals need to pay attention to sleep quality and HRQOL in renal transplant recipients and take appropriate measures to improve patients' sleep quality and HRQOL.

To examine the responsiveness of Functional Assessment of Cancer Therapy-Prostate (FACT-P) and Short Form-12 Health Survey version 2 (SF-12 v2) in prostate cancer patients because there is a lack of evidence to support their responsiveness in this patient population. One hundred sixty-eight subjects with prostate cancer were surveyed at baseline and at 6 months using the SF-12 v2 and FACT-P version 4. Internal responsiveness was assessed using paired t test and generalized estimating equation. External responsiveness was evaluated using receiver operating characteristic curve analysis. The internal responsiveness of the FACT-P and SF-12 v2 to detect positive change was satisfactory. The FACT-P and SF-12 v2 could not detect negative change. The FACT-P and the SF-12 v2 performed the best in distinguishing between improved general health and worsened general health. The FACT-P performed better in distinguishing between unchanged general health and worsened general health. The SF-12 v2 performed better in distinguishing between unchanged general health and improved general health. Positive change detected by these measures should be interpreted with caution as they might be too responsive to detect "noise," which is not clinically significant. The ability of the FACT-P and the SF-12 v2 to detect negative change was disappointing. The internal and external responsiveness of the social well-being of the FACT-P cannot be supported, suggesting that it is not suitable to longitudinally monitor the social component of HRQOL in prostate cancer patients. The study suggested that generic and disease-specific measures should be used together to complement each other.

To explore young women's health-related quality of life (HRQOL) and investigate whether menstrual and menarche experiences and objectification predict mental and physical health components of HRQOL. Menstruation plays a fundamental role in female biology, in women's relationship to their bodies and consequently in women's health and their HRQOL. Cross-sectional explorative survey design. A questionnaire that included the SF-36v2, the Self-objectification Questionnaire (SOQ), the Body Surveillance and Body Shame subscales of the Objectified Body Consciousness Scale, the Belief and Attitudes Towards Menstruation Questionnaire (four subscales), and questions on menarche and menstruation was administered at the end of 2013 to 319 Icelandic women who represented the population by age. The SF-36v2 includes eight dimensions addressing the mental and physical components of HRQOL. Scores are presented as raw data scores and scores based on standardised score of American women and range from 0 to 100 with higher scores indicating better HRQL. A hierarchical multiple linear regression model was employed to calculate significant predictors of mental and physical health components of HRQOL. Mean raw data scores on SF36-v2 dimensions ranged from 54.7 to 91.5. The participants scored below the standardised, mean norm-based score for all dimensions. Secrecy of menstruation, experience of body shame and pain during menstruation predicted worse mental HRQOL. To believe in the proscriptive role and the unpleasantness of menstruation, experience of body shame, medication for menstrual pain and not holding a university education predicted worse physical HRQOL. These two models explained 30% and 22% of the variance of the mental and physical components of SF36-v2, respectively. Young women's mental and physical HRQOL is influenced by the specific context of their lives. Women's health education should take into account the various relationships women may have with their bodies. © 2017

Full Text Available Industrial wind turbines (IWTs are a new source of noise in previously quiet rural environments. Environmental noise is a public health concern, of which sleep disruption is a major factor. To compare sleep and general health outcomes between participants living close to IWTs and those living further away from them, participants living between 375 and 1400 m (n = 38 and 3.3 and 6.6 km (n = 41 from IWTs were enrolled in a stratified cross-sectional study involving two rural sites. Validated questionnaires were used to collect information on sleep quality (Pittsburgh Sleep Quality Index - PSQI, daytime sleepiness (Epworth Sleepiness Score - ESS, and general health (SF36v2, together with psychiatric disorders, attitude, and demographics. Descriptive and multivariate analyses were performed to investigate the effect of the main exposure variable of interest (distance to the nearest IWT on various health outcome measures. Participants living within 1.4 km of an IWT had worse sleep, were sleepier during the day, and had worse SF36 Mental Component Scores compared to those living further than 1.4 km away. Significant dose-response relationships between PSQI, ESS, SF36 Mental Component Score, and log-distance to the nearest IWT were identified after controlling for gender, age, and household clustering. The adverse event reports of sleep disturbance and ill health by those living close to IWTs are supported.

In brain tumor (BT) patients, the association between health-related quality of life (HRQoL) and psychological characteristics remains largely unknown. We evaluated the association of personality traits, clinical factors, psychological distress symptoms, and cognitive state with HRQoL in BT patients. On admission for BT surgery, 200 patients (69 % women; age 55.8 ± 14.5 years) were evaluated for HRQoL (SF-36 scale), Big-Five personality traits (Ten-Item Personality Inventory), psychological distress symptoms (Hospital Anxiety and Depression Scale or HADS), cognitive function (Mini-Mental State Examination or MMSE) and clinical characteristics, including functional status (Barthel index or BI). The most common BT diagnoses were meningioma (39 %) and high-grade glioma (18 %). Only factors significantly associated with SF-36 domains in univariable regression analyses were included in their respective multivariable models and predicted from 6 %-49 % of the total variance of SF-36 scores. Greater TIPI emotional stability score was independently associated with greater SF-36 emotional well-being (β = 0.23, p emotional well-being score (β = 0.13, p = 0.02). HADS-anxiety and HADS-depression scores were the strongest independent determinants of all, except physical functioning, SF-36 scores (β-values range from 0.14 to 0.56; p values ≤ 0.03). BI score was the strongest independent determinant of SF-36 physical functioning score (β = 0.36, p emotional well-being and social functioning SF-36 scores. Consciousness and emotional stability should be considered important personality-related determinants of HRQoL in BT patients. Psychological distress, functional disability, and cognitive impairment are also important predictors of HRQoL.

Primary biliary cirrhosis and Primary sclerosing cholangitis are autoimmune cholestatic liver diseases sharing a lot in common, including a significant impairment of patients' health-related quality of life HRQoL HRQoL in PBC is assessed with disease-specific PBC-40 and PBC-27 questionnaires. A PSC-specific questionnaire has not been developed. Neither PBC-40 nor PBC-27s applicability for PSC has been evaluated. We applied these three questionnaires for HRQoL assessment in a large homogenous cohort of PSC patients. This cross-sectional study enrolled 102 Caucasian PSCs and 53 matched healthy controls and measured HRQoL using generic SF-36, and disease-specific (PBC-40/PBC-27) questionnaires. (i) SF-36. Most SF-36 domains were significantly lower in PSCs than controls. Physical Functioning and Mental Component Summary scores were significantly lower in female patients and correlated negatively with age but not with concurrent inflammatory bowel disease. Cirrhosis was associated with lower Physical Functioning, Role Physical, General Health, Vitality and Physical Component Summary. (ii) PBC-40 and PBC-27. Both tools showed similar HRQoL impairment scoring. Fatigue and Cognitive were impaired in female patients. Several correlations existed between HRQoL and laboratory parameters, including cholestatic tests and Itch. Cirrhosis correlated with Other symptoms and Fatigue PBC-40. (iii) PBC-40 vs PBC-27. Strong correlations among most domains of both questionnaires were seen, as well as between (iv) SF-36 vs PBC-40 or SF-36 vs PBC-27. This is the first study directly comparing PBC-40, PBC-27 and SF-36 in PSC. PSC patients, especially females, show HRQoL impairment. PBC-40 and PBC-27 questionnaires could be of potential use for HRQoL assessment in PSC. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate working conditions associated with health-related quality of life (HRQL) among nursing providers. Cross-sectional study conducted in a university hospital in the city of São Paulo, Southeastern Brazil, during 2004-2005. The study sample comprised 696 registered nurses, nurse technicians and nurse assistants, predominantly females (87.8%), who worked day and/or night shifts. Data on sociodemographic information, working and living conditions, lifestyles, and health symptoms were collected using self-administered questionnaires. The following questionnaires were also used: Job Stress Scale, Effort-Reward Imbalance (ERI) and Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Ordinal logistic regression analysis using proportional odds model was performed to evaluate each dimension of the SF-36. Around 22% of the sample was found to be have high strain and 8% showed an effort-reward imbalance at work. The dimensions with the lowest mean scores in the SF-36 were vitality, bodily pain and mental health. High-strain job, effort-reward imbalance (ERI>1.01), and being a registered nurse were independently associated with low scores on the role emotional dimension. Those dimensions associated to mental health were the ones most affected by psychosocial factors at work. Effort-reward imbalance was more associated with health than high-strain (high demand and low control). The study results suggest that the joint analysis of psychosocial factors at work such as effort-reward imbalance and demand-control can provide more insight to the discussion of professional roles, working conditions and HRQL of nursing providers.

To report the results of a Latin American consensus panel regarding the diagnosis and management of primary open-angle glaucoma and to compare these results with those from a similar panel in the United States. A RAND-like (Research and Development) appropriateness methodology was used to assess glaucoma practice in Latin America. The 148 polling statements created for the RAND- like analysis in the United States and 10 additional statements specific to glaucoma care in Latin America were presented to a panel of Latin American glaucoma experts. Panelists were polled in private using the RAND- like methodology before and after the panel meeting. Consensus agreement or disagreement among Latin American experts was reached for 51.3% of statements before the meeting and increased to 66.5% in the private, anonymous meeting after polling (79.0% agreement, 21.0% disagreement). Although there was a high degree of concordance (111 of 148 statements; 75%) between the results of this Latin American panel and the United States panel, there were some notable exceptions relating to diagnostic and therapeutic decision making. This RAND-like consensus methodology provides a perspective of how Latin American glaucoma practitioners view many aspects of glaucoma and compares these results with those obtained using a similar methodology from practitioners in the United States. These findings may be helpful to ophthalmologists providing glaucoma care in Latin America and in other regions of the world. Copyright © 2012 Elsevier Inc. All rights reserved.

SF6 and the greenhouse effect

International Nuclear Information System (INIS)

Gjaerde, Anne Cathrine; Rein, Asgaut; Hegerberg, Rolf; Kulsetaas, John

1997-01-01

The gas SF 6 (sulfur hexafluoride) is much used as an insulation medium in electric switchgear and breakers. However, there has been some recent concern about the possible contribution of SF 6 to the global greenhouse effect. This report presents some collected facts about SF 6 emission. The concentration of SF 6 in the atmosphere is very low and will probably remain so until the end of the next century. Hence the contribution of SF 6 to the greenhouse effect is negligible. Most of the SF 6 emission comes from the magnesium and aluminium industries. In 1993, SF 6 emission from switchgear in the Norwegian distribution grid corresponded to only 0.2 per million of the CO 2 emission in Norway. But the quantity of SF 6 accumulated in electric switchgear is considerable. However, losing it to the atmosphere can be avoided by using recirculation or destruction systems for SF 6 in connection with maintenance and replacement of components. Norwegian climate policy aims at taking measures against SF 6 and other climate gases on a par with CO 2 . Taxation measures have been suggested for SF 6 . Atmospheric SF 6 does not influence the ozone layer. 3 refs., 8 figs

Full Text Available Abstract Background Few epidemiologic studies have assessed health-related quality of life (HRQL of asthma patients from a general population and it is unclear which instrument is best suitable for this purpose. We investigated the validity of the Asthma Quality of Life Questionnaire (AQLQ and the SF-36 completed by individuals with asthma from the population-based SAPALDIA (Swiss study on air pollution and lung diseases in adults cohort. Methods The study included 258 participants with a physician-diagnosed asthma who had completed the AQLQ and SF-36. We assessed floor and ceiling effects, internal consistency reliability and cross-sectional validity with a priori hypotheses that correlations between the specific HRQL domains (e.g. "symptoms" or "physical functioning" and the corresponding external validation measures (respiratory symptoms, need for doctor visits, limitation in activities due to asthma and lung function would capture similar aspects and be correlated moderately (≥ 0.3 to strongly (≥ 0.5, whereas non-corresponding domains be correlated weakly with each other ( Results The AQLQ showed pronounced ceiling effects with all median domain scores above 6 (scores varied from 1–7. For the SF-36, ceiling effects were present in 5 out of 8 domains. Cronbach's alpha was >0.7 for all AQLQ and SF-36 domains. Correlations between the AQLQ domains "respiratory symptoms", "activity limitation" and "environmental exposure", and the validation measures ranged from 0.29–0.57. Correlations between the "emotional function" domain and the validation measures were also in this range (0.31–0.55 and not as low as we hypothesized. For the SF-36, correlations between "physical functioning" and "role physical", and the validation measures ranged from 0.25–0.56, whereas "role emotional" and "mental health" correlated with these measures from 0.01–0.23. Conclusion The AQLQ and the SF-36 showed fairly good internal consistency. Both instruments

Kevric, Jasmina; Papa, Nathan; Perera, Marlon; Rashid, Prem; Toshniwal, Sumeet

Poor mental health in junior clinicians is prevalent and may lead to poor productivity and significant medical errors. We aimed to provide contemporary data on the mental health of surgical trainees and identify risk factors relating to poorer mental health outcomes. A detailed questionnaire was developed comprising questions based on the 36-item short-form health survey (SF-36) and Physical Activity Questionnaire. Each of the questionnaires has proven validity and reliability in the clinical context. Ethics approval was obtained from the Royal Australasian College of Surgeons. The questionnaire was aimed at surgical registrars. We used Physical Activity Questionnaire, SF-36 scores and linear regression to evaluate the effect of putative predictors on mental health. A total of 83 responses were collected during the study period, of which 49 (59%) were from men and 34 (41%) were from women. The mean Mental Component Summary (MCS) score for both sexes was significantly lower than the population mean at ages 25-34 (p work culture and a feeling of a lack of support at work were extremely strong predictors of a lower MCS score (p Hours of overtime worked, particularly unpaid overtime, were also strong predictors of a poorer score. Australian surgical trainees reported lower MCS scores from the SF-36 questionnaire compared to the general population. Increasing working hours, unpaid overtime, poor job security, and job satisfaction were associated with poorer scores among trainees. Interventions providing improved working conditions need to be considered by professional training bodies and employers. Copyright © 2018 Association of Program Directors in Surgery.

The aim of current research is to analyze the psychometric properties of the Spanish version of the SF-8, overcoming previous shortcomings. A double line of analyses was used: competitive structural equations models to establish factorial validity, and Item Response theory to analyze item psychometric characteristics and information. 593 people aged 60 years or older, attending long life learning programs at the University were surveyed. Their age ranged from 60 to 92 years old. 67.6% were women. The survey included scales on personality dimensions, attitudes, perceptions, and behaviors related to aging. Competitive confirmatory models pointed out two-factors (physical and mental health) as the best representation of the data: χ2(13) = 72.37 (p < .01); CFI = .99; TLI = .98; RMSEA = .08 (.06, .10). Item 5 was removed because of unreliability and cross-loading. Graded response models showed appropriate fit for two-parameter logistic model both the physical and the mental dimensions. Item Information Curves and Test Information Functions pointed out that the SF-8 was more informative for low levels of health. The Spanish SF-8 has adequate psychometric properties, being better represented by two dimensions, once Item 5 is removed. Gathering evidence on patient-reported outcome measures is of crucial importance, as this type of measurement instruments are increasingly used in clinical arena.

THE MEANINGFUL ACTIVITY PARTICIPATION ASSESSMENT: A MEASURE OF ENGAGEMENT IN PERSONALLY VALUED ACTIVITIES*

EAKMAN, AARON M.; CARLSON, MIKE E.; CLARK, FLORENCE A.

2011-01-01

The Meaningful Activity Participation Assessment (MAPA), a recently developed 28-item tool designed to measure the meaningfulness of activity, was tested in a sample of 154 older adults. The MAPA evidenced a sufficient level of internal consistency and test-retest reliability and correlated as theoretically predicted with the Life Satisfaction Index-Z, the Satisfaction with Life Scale, the Engagement in Meaningful Activities Survey, the Purpose in Life Test, the Center for Epidemiologic Studies Depression Inventory and the Rand SF-36v2 Health Survey subscales. Zero-order correlations consistently demonstrated meaningful relationships between the MAPA and scales of psychosocial well-being and health-related quality of life. Results from multiple regression analyses further substantiated these findings, as greater meaningful activity participation was associated with better psychological well-being and health-related quality of life. The MAPA appears to be a reliable and valid measure of meaningful activity, incorporating both subjective and objective indicators of activity engagement. PMID:20649161

Background:Early-onset major depressive disorder (MDD) (EOD) is often particularly malignant due to its special clinical features,accompanying impaired social function,protracted recovery time,and frequent recurrence.This study aimed to observe the effects of age onset on clinical characteristics and social function in MDD patients in Asia.Methods:In total,547 out-patients aged 18-65 years who were from 13 study sites in five Asian countries were included.These patients had MDD diagnose according to the Diagnostic and Statistical Manual of Mental Disorders,4th Edition criteria.Clinical features and social function were assessed using Symptom Checklist-90-revised (SCL-90-R) and Sheehan Disability Scale (SDS).Quality of life was assessed by a 36-item Short-form Health Survey (SF-36).Analyses were performed using a continuous or dichotomous (cut-off:30 years)age-of-onset indicator.Results:Early-onset MDD (EOD,＜30 years) was associated with longer illness (P =0.003),unmarried status (P ＜ 0.001),higher neuroticism (P ≤ 0.002) based on the SCL-90-R,and more limited social function and mental health (P =0.006,P =0.007) based on the SF-36 and SDS.The impairment of social function and clinical severity were more prominent at in-patients with younger onset ages.Special clinical features and more impaired social function and quality of life were associated with EOD,as in western studies.Conclusions:EOD often follows higher levels of neuroticism.Age of onset of MDD may be a predictor of clinical features and impaired social function,allowing earlier diagnosis and treatment.

Legal issues concerning mine closure and social responsibility on the West Rand

Directory of Open Access Journals (Sweden)

Francois Durand

2009-04-01

Full Text Available Mining and, especially, gold and uranium mining have played a major role in the economy, history, and demography of South Africa. The contribution of the mines to the economy of South Africa over the past century has been overvalued, while the social injustices and negative environmental impacts that accompanied mining have been underplayed or ignored by the mining houses and government. The environmental situation has worsened significantly over the past few years due to the abandonment and pending closure of most of these mines. A reluctance is perceived on the part of the mining companies, and even government, to take responsibility for the damage caused by pollution, ecological degradation, and impact on human health by mining. Instead, the current informal policy appears to take smaller companies to court on minor environmental injustices to, perhaps, impress the broader public, while one of the biggest environmental concerns is stylishly treated. The inability of government to address the damage by mines effectively is in conflict with the National Water Act, the National Environmental Management Act, the Mineral and Petroleum Resources Act, the National Nuclear Regulator Act, and the Constitution of South Africa. The authors propose a multidisciplinary approach to address water-related environmental injustices on the West Rand and Far West Rand. We also describe the application of the National Environmental Management Act of South Africa (Act No. 107 of 1998 in the Wonderfonteinspruit and Tweelopiespruit Catchments and the current water quality situation.

Patients suffering from major depressive disorder (MDD) have been reported to have substantial long-lasting limitations in multiple domains of health-related quality of life (HRQoL). The thoughtful assessment of HRQoL and the impact of treatment response on HRQoL are emerging as important issues in the care of patients with major depressive disorder. One hundred and three patients meeting Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for MDD took fluoxetine (20 mg/d) for 6 weeks and were assessed by the Short Form 36 Health Survey (SF-36), the 17-item Hamilton Depression Rating (HAMD-17) and the Clinical Global Impression (CGI) scales. Relationships between SF-36 scores and depressive symptom severity and early change of these symptoms were tested. SF-36 component scores at week 6 were higher than those at baseline (all P ≤ 0.0058). Scores for general health were significantly higher in responders than non-responders (P = 0.0009). The overall HAMD-17 and CGI scores at 2- and 6-week follow-up were significantly lower than those at baseline (P ≤ 0.0001). Higher scores for anxiety/somatization were significantly associated with poorer SF-36 scores at baseline (P = 0.0001); role-physical scores at week 6 were positively correlated with reduction rate of anxiety/somatization in 2-week follow-up (P = 0.0002). Depressive symptom severity was associated with HRQoL in patients with MDD. HRQoL may vary with severity of depression and/or anxiety-somatization at baseline.

The relationship between perceived health and walker use has seldom been addressed. Concerns over falls and falls risk are precursors to walker use. We compared the SF-36 scores of 26 women and 14 men, mean age 86.8 +/- 6.0 years based on walker use and faller status. An analysis of covariance (ANCOVA) with age as the covariate, compared groups for the SF-36 constructs and totals score. Significant differences were noted between walker users and nonusers in physical functioning, role limitations due to physical problems, general health, and the total SF-36 score. Pairwise comparisons favored nonusers, while no differences were seen due to faller status. Walker use is associated with lower self-perceptions of physical functioning, role limitations due to physical problems, and general health in assisted-living residents. Faller status is not associated with self-perceived health status. Although walker use aids mobility and lowers the probability of falls, further research is needed to determine if the prescription of assistive devices has a more negative impact on self-perceived health than does falling. This possibility could be explained, in part, by the greater activity levels of those individuals who do not depend on walkers.

In addition, to explore the association between age, gender, height, educational level and different aspects of health status of adults with short stature. Methods A questionnaire was mailed to 72 subjects with short stature registered in the database of a Norwegian resource centre for rare disorders, response rate 61% (n = 44, age 16–61. Health status was assessed with SF-36 version 2. Comparison was done with age and gender matched samples from the general population in Norway (n = 264 and from subjects with RA (n = 88. Results The ShSt sample reported statistically significant impaired health status in all SF-36 subscales compared with the GP sample, most in the physical functioning, Mean Difference (MD 34 (95% Confidence Interval (CI 25–44. The ShSt reported poorer health status in mental health, MD 11 (95% CI 4–18 and social functioning, MD 11 (95% CI 2–20 but better in role physical MD 13 (95% CI 1–25 than the RA sample. On the other subscales there were minor difference between the ShSt and the RA sample. Within the short stature group there was a significant association between age and all SF-36 physical subcales, height was significantly associated with physical functioning while level of education was significantly associated with mental health. Conclusion People with short stature reported impaired health status in all SF-36 subscales indicating that they have health problems that influence their daily living. Health status seems to decline with increasing age, and earlier than in the general population.

Perspectives for RandD in Bioenergy in the Baltic States

Energy Technology Data Exchange (ETDEWEB)

Holmberg, Rurik (Technopolis Group, Stockholm (Sweden) )

2009-11-15

This study has identified two almost contradictory trends regarding bioenergy in the Baltic States. On the one hand, RandD performed in bioenergy in the Baltic States is rather limited. This might be somewhat surprising, because on the other hand various forms of bioenergy are either already used on a large scale or are widely assumed to become important in the near future. Bioenergy is explicitly recognized in various policy plans as an important component of the energy system in all the Baltic States. Thus the limited RandD efforts raise a number of questions, which probably lack unequivocal answers, but which would be important to discuss in the Baltic States. In all three Baltic States, bioenergy has a major potential. The present trend with boiler houses using biomass in a district heating systems commenced in the 1990s with significant foreign support. Technology was mainly imported, but in some cases local producers have drawn upon these experiences and become producers in their own right. The result has been that the Baltic States have relatively well developed bioenergy technology in use in district heating. But perhaps more importantly, there is know-how and experience in the Baltic States from the use of bioenergy, which however needs to be constantly upgraded. Regarding interest groups, one question raised by some interviewees was whether the natural gas industry with Russian Gazprom as the key player has a bigger say in the energy policy of the Baltic States than officially admitted. Although this issue remains speculative, the question as such is justified and should not be omitted from the discussion. The interest groups behind bioenergy are relatively weak, at least in comparison with other interest groups in the energy sector. As long as the farmers' organizations are not unambiguously behind bioenergy, the political support for investments in developing new technology is likely to remain lukewarm.

The aim of this study was to determine the emotional and sociodemographic characteristics of patients with ankylosing spondylitis (AS) and to investigate the impact of the disease on their social life and quality of life (QOL). This study included 101 patients with the diagnosis of AS. All patients filled in a questionnaire comprising their sociodemographic and emotional status and their self-rating on the disease and completed the 36-item Short Form Health Survey (SF-36). The impact of the disease on work status, sexuality, and family relations was measured on a Likert scale. The impact of the disease on employment, family and sexual relations, work life as well as SF-36 was investigated. Therefore, the effect of educational level, employment, social security, and sexual relations with spouse, etc. on QOL were assessed. More than half of the patients had no knowledge about the disease and half of them were not under a physician's control. Thirty-two percent of the previously working patients quit their jobs because of the disease. Quitting a job due to the disease was more frequent in the first 10 years of the disease. The most affected domains of the SF-36 were physical role power, general health, and pain. Patients unemployed due to the disease had lower SF-36 scores compared with employed ones. Unemployed patients without social insurance had lower values on SF-36 subscales (prelations (pwork and social life. Work disability affects QOL. Educating the patients about the disease may play an important role in improving his/her life quality and coping with the disease. Thus, the socioeconomic burden of the disease on the person and on society can be diminished.

The Rand Flora is a well-known floristic pattern in which unrelated plant lineages show similar disjunct distributions in the continental margins of Africa and adjacent islands-Macaronesia-northwest Africa, Horn of Africa-Southern Arabia, Eastern Africa, and Southern Africa. These lineages are now separated by environmental barriers such as the arid regions of the Sahara and Kalahari Deserts or the tropical lowlands of Central Africa. Alternative explanations for the Rand Flora pattern range from vicariance and climate-driven extinction of a widespread pan-African flora to independent dispersal events and speciation in situ. To provide a temporal framework for this pattern, we used published data from nuclear and chloroplast DNA to estimate the age of disjunction of 17 lineages that span 12 families and nine orders of angiosperms. We further used these estimates to infer diversification rates for Rand Flora disjunct clades in relation to their higher-level encompassing lineages. Our results indicate that most disjunctions fall within the Miocene and Pliocene periods, coinciding with the onset of a major aridification trend, still ongoing, in Africa. Age of disjunctions seemed to be related to the climatic affinities of each Rand Flora lineage, with sub-humid taxa dated earlier (e.g., Sideroxylon) and those with more xeric affinities (e.g., Campylanthus) diverging later. We did not find support for significant decreases in diversification rates in most groups, with the exception of older subtropical lineages (e.g., Sideroxylon, Hypericum, or Canarina), but some lineages (e.g., Cicer, Campylanthus) showed a long temporal gap between stem and crown ages, suggestive of extinction. In all, the Rand Flora pattern seems to fit the definition of biogeographic pseudocongruence, with the pattern arising at different times in response to the increasing aridity of the African continent, with interspersed periods of humidity allowing range expansions.

To assess reliability, construct validity, responsiveness, and interpretability for Neck OutcOme Score (NOOS), Neck Disability Index (NDI), and Short Form-36 (SF-36) in neck pain patients. Internal consistency was assessed by Cronbach alpha. Test-retest reliability was evaluated by intraclass correlation coefficient (ICC), and measurement error was estimated from the standard error of measurement. Responsiveness was assessed as standardized response mean (SRM) and interpretability from the minimal important difference (MID). Construct validity was tested correlating subscale scores from NOOS and SF-36 and NDI items. At baseline, 196 neck pain patients were included. Cronbach α was adequate for most NOOS subscales, NDI, and SF-36 with few exceptions. Good to excellent reliability was found for NOOS subscales (ICC 0.88-0.95), for NDI, and for SF-36 with few exceptions. For NOOS, minimal detectable changes varied between 1.1 and 1.9, and construct validity was supported. SRMs were higher for NOOS subscales (0.19-0.42), compared to SF-36 and NDI. MID values varied between 15.0 and 24.1 for NOOS subscales. In conclusion, the NOOS is a reliable, valid, and responsive measure of self-reported disability in neck pain patients, performing at least as well or better than the commonly used SF-36 and NDI.

Kelleher, M O

2012-02-03

The objective of the investigation was to report on the health-related quality of life (HRQoL) of patients diagnosed with skull base tumours using the Short Form Health Survey questionnaire (SF-36). Those patients suffering with vestibular schwannoma were examined to determine the effect facial nerve function had on their quality of life. It took place at the tertiary referral centre at the Department of Clinical Neurosciences, Western General Hospital, Edinburgh. A prospective study of 70 consecutive patients was taken, who harboured the following tumours: 54 vestibular schwannomas, 13 meningiomas, two haemangioblastomas and one hypoglossal schwannoma. Patients were interviewed using the short form 36 (SF-36) questionnaire. Facial nerve function was assessed in those patients who had vestibular schwannomas. The entire cohort of live skull base patients were assessed after a median follow-up time of 38.4 months. Patients with vestibular schwannoma treated conservatively with interval MRI had a quality of life similar to t he normal population. Those who underwent surgery had a significant difference in two of the SF-36 domains. No statistically significant correlation was found at final assessment between the degree of facial nerve functioning and any of the domains of SF-36. Patients with non-vestibular tumours had an impaired HRQoL in seven of the eight domains. Patients with skull base tumours have a significant impairment of their HRQoL. A conservative policy of follow up with interval MRI for patients with small vestibular schwannomas may therefore be more appropriate to preserve their HRQoL. Facial nerve outcome has little influence on quality of life in vestibular schwannoma patients.

This study investigated a possible pathway of the childrearing context and maternal mental health at 6 months, and how these factors influence children's development at 6, 18 and 36 months. Using random sampling, 2048 children and mothers were selected. The mother's health status was evaluated using the Taiwanese version of the 36-Item Short Form Health Survey (SF-36), and infant development was assessed using the high reliable Taiwan birth cohort study instrument. All data were collected using parental self-report, and were analysed using multiple linear regression analysis and further pathway using structural equation modelling. This study showed that 12 factors effected children's development at 6 months, and some dissipated with growth. Of these, maternal education had an enduring effect on different domains of child development, and this effect intensified as the child grew older. Children who grew up in a family with more siblings would show a delay in language development at 6 months; they have a delay in motor and social development at 18 and 36 months. Additionally, maternal mental health effected the children's fine motor development at 6 months. However, this effect disappeared at 18 months, and influenced children's social development at 36 months. This study demonstrated that the development of children at as young as 6 months is affected by various factors. These factors may dissipate, continue to influence child development up to 3 years of age, turn from being disadvantageous to beneficial, or affect different domains of child development. Also, parental self-report instrument might be has its limitation and could be contributed by several confounding factors. Thus, continuous longitudinal follow-up on changes in maternal conditions, family factors, and environmental factors is vital to understand how these early infantile factors affect each other and influence the developmental trajectories of children into early childhood. © 2010 Blackwell

Full Text Available Abstract Background/Aim As Thai people living with HIV/AIDS gain increasing access to antiretroviral (ARV therapy, it is important to evaluate the impact this has not only on clinical outcomes, but also on patients' functional status and well-being. In this study, we translated, culturally adapted and tested the reliability and validity of two widely-used health-related quality of life questionnaires - the MOS-HIV Health Survey and the SF-12 - in people living with HIV/AIDS in Northern Thailand. Methods: Questionnaires were administered to 100 patients at community hospital outpatient ARV clinics in northern Thailand. Reliability was estimated using Cronbach's alpha, while evidence for validity was tested using known-groups comparison based on CD4 group, symptom distress score, bed days and days of reduced activity in the past three months. Results Patients' median age was 36, with 58% female, 58% working as laborers, and 60% completing at least primary education. Median CD4 count was 218 cells/mm3. There were no missing data. For the MOS-HIV and SF-12, mean physical summary scores were 53.1 and 49.0 respectively; mean mental summary scores were 53.4 and 45.6, respectively. Internal consistency coefficients were >0.7 for all but one scale, the PF scale (0.67. As hypothesized, scores were slightly to moderately correlated with CD4 count, symptom score, number of days in bed or with reduced activity. Correlations were higher with physical health scores than with mental health scales. The MOS-HIV discriminated clinical known groups slightly better than the SF-12. Conclusion Both the MOS-HIV and the shorter SF-12 were successfully adapted for people with HIV/AIDS in Northern Thailand, and showed encouraging evidence for reliability and validity. These patient reported questionnaires could be valuable tools in evaluating therapeutic interventions and other innovations in health and social services, and to estimate health needs and population

We evaluated the impact of a 1-wk activity program on the health, quality of life (QOL), and occupational performance of community-living women diagnosed with cancer. A one-group pretest-posttest repeated-measures design was used. Participants completed a functional health measure (36-Item Short Form Health Survey [SF-36]), a QOL measure (World Health Organization Quality of Life-Brief version [WHOQOL-BREF]), and an occupational performance and satisfaction measure (Canadian Occupational Performance Measure [COPM]) before and 6 wk after program completion. The COPM was also administered on Day 5. Paired t tests for the SF-36 and WHOQOL-BREF showed no significant differences, except for the WHOQOL-BREF's Social Relationships subscale (p occupational performance and satisfaction and social relationships of community-living women diagnosed with cancer.

Full Text Available Multiple sclerosis (MS patients, in general, show reduced physical function, physical activity, and quality of life. Positive associations between physical activity and quality of life have been reported. In particular, we were interested in the relation between physical activity and mental health in MS patients without limitation of physical function, since limitations of physical function may influence both physical activity and quality of life. Assessment comprised the Baecke questionnaire on physical activity, the Short Form 36 Health Survey (SF-36, and Beck Depression Inventory (BDI. We ranked our sample according to physical activity into four groups and performed an ANOVA to analyze the relationship between levels of physical activity and health-related quality of life (HRQoL. Then we performed a subgroup analysis and included patients with unlimited walking distance and a score of less than 18 in the BDI. Most active vs. inactive patients were compared for the mental subscales of the SF-36 and depression scores. From 632 patients, 265 met inclusion criteria and hence quartiles were filled with 67 patients each. Active and inactive patients did not differ considerably in physical function. In contrast, mental subscales of the SF-36 were higher in active patients. Remarkable and significant differences were found regarding vitality, general health perception, social functioning and mental health, all in favor of physically active patients. Our study showed that higher physical activity is still associated with higher mental health scores even if limitations of physical function are accounted for. Therefore, we believe that physical activity and exercise have considerable health benefits for MS patients.

The outcome following traumatic brain injury (TBI) is heterogeneous and poorly defined and physical disability scales like the extended Glasgow Outcome Score (GOSE) while providing valuation information in terms of broad categorisation of outcome are unlikely to capture the full spectrum of deficits. Quality of life questionnaires such as SF-36 are emerging as potential tools to help characterise factors important to patients' recovery. This study assessed the association between physical disability and subjective health rating. The relationship is of value as it may help evaluate the impact of TBI on patients' lives and facilitate the delivery of appropriate neuro-rehabilitation services. A single-centre retrospective study was undertaken to assess the relationship between physical outcome as measured by GOSE and quality of life captured by the SF-36 questionnaire. Cronbach's alpha was calculated for each of the eight SF-36 domains to measure internal consistency of the test. Multivariate analysis of variance was conducted to look at the association between GOSE and the physical (PCS) and mental (MCS) component scores on the SF-36. Finally, we performed a generalised linear mixed model (GLMM) to assess the relative contribution of GOSE score, age at the time of trauma, sex and TBI duration towards MCS and PCS rating. There is a statistically significant difference in the MCS and PCS scores based on patients' GOSE scores. The mean scores of the eight SF-36 domains showed significant association with GOSE. GLMM demonstrated that GOSE was the strongest predictor of PCS and MCS. Age was an important variable in the PCS score while time following trauma was a significant predictor of MCS rating. This study highlights that patients' physical outcome following TBI is a strong predictor of the subjective mental and physical health. Nevertheless, there remains tremendous variability in individual SF-36 scores for each GOSE category, highlighting that additional factors

Cross-sectional cohort. The purpose of this study is to provide a model to allow estimation of utility from the Short Form (SF)-6D using data from the Oswestry Disability Index (ODI), Back Pain Numeric Rating Scale (BPNRS), and the Leg Pain Numeric Rating Scale (LPNRS). Cost-utility analysis provides important information about the relative value of interventions and requires a measure of utility not often available from clinical trial data. The ODI and numeric rating scales for back (BPNRS) and leg pain (LPNRS), are widely used disease-specific measures for health-related quality of life in patients with lumbar degenerative disorders. The purpose of this study is to provide a model to allow estimation of utility from the SF-6D using data from the ODI, BPNRS, and the LPNRS. SF-36, ODI, BPNRS, and LPNRS were prospectively collected before surgery, at 12 and 24 months after surgery in 2640 patients undergoing lumbar fusion for degenerative disorders. Spearman correlation coefficients for paired observations from multiple time points between ODI, BPNRS, and LPNRS, and SF-6D utility scores were determined. Regression modeling was done to compute the SF-6D score from the ODI, BPNRS, and LPNRS. Using a separate, independent dataset of 2174 patients in which actual SF-6D and ODI scores were available, the SF-6D was estimated for each subject and compared to their actual SF-6D. In the development sample, the mean age was 52.5 +/- 15 years and 34% were male. In the validation sample, the mean age was 52.9 +/- 14.2 years and 44% were male. Correlations between the SF-6D and the ODI, BPNRS, and LPNRS were statistically significant (P < 0.0001) with correlation coefficients of 0.82, 0.78, and 0.72, respectively. The regression equation using ODI, BPNRS,and LPNRS to predict SF-6D had an R of 0.69 and a root mean square error of 0.076. The model using ODI alone had an R of 0.67 and a root mean square error of 0.078. The correlation coefficient between the observed and estimated

Patients with hyperventilation syndrome (HVS) report severe symptom-related suffering and often complain from insufficient medical attention. However, quality of life data in this context are scarce. We aimed at assessing the health-related quality of life (HRQoL) of HVS patients. Twenty-one HVS patients with extensive cardiorespiratory workup including cardiopulmonary exercise testing (CPET) filled in the generic SF-36 questionnaire and the results were compared to French normal values. Correlations between SF36 dimensions and clinical and functional data were established. All SF-36 scores were markedly decreased in HVS patients compared to healthy subjects: Physical Functioning: 44 ± 24, Social Functioning: 57 ± 27, Role Physical: 21 ± 32, Role Emotional: 48 ± 42, Mental Health: 51 ± 27, Vitality: 34 ± 20, Body Pain: 41 ± 21, General Health: 42 ± 21. These figures were all significantly lower in the HVS patients respective to the normal reference population. They were also lower than corresponding values published in patients with asthma or chronic obstructive pulmonary disease (COPD). "Vitality" and "Physical Functioning" scores were correlated with Nijmegen score (r = -0.594, p = 0.047) and peak respiratory frequency during CPET (r = -0.644, p = 0.019). The SF-36 Social Functioning score was correlated with the ventilatory threshold (r = 0.629, p = 0.034), peak V'E/V'CO2 (ventilation/CO2 production) (r = 0.650, p = 0.016) and peak PaCO2 (r = -0.664, p = 0.027). In conclusion, this study shows that HRQoL can be severely impaired in patients with HVS, which is one more reason to take this condition seriously. Copyright © 2013 Elsevier Ltd.

Bovet, Claire; Carlson, Matthew; Taylor, Matthew

2016-08-01

Ehlers-Danlos Syndrome, hypermobility type (EDS-HT) and the joint hypermobility syndrome (JHS) are connective tissue disorders that form an overlapping clinical syndrome and are associated with frequent medical visits and substantial morbidity. EDS-HT/JHS-associated pain correlates with poor quality of life. While physical therapy is the recommended treatment for EDS-HT/JHS, little is known about therapy-related patient experiences and iatrogenic injuries. We studied 38 adult EDS-HT/JHS patients, eliciting health-related quality of life (HRQoL) from 28 patients through the RAND SF-36 questionnaire. We also explored physical therapy experiences through focus groups with 13 patients. Our patients displayed poor HRQoL, with 71% reporting worse health over the past year. SF-36 scores were significantly lower than the scores of the average American population (P < 0.001 for 8 of 10 categories assessed), but were comparable to EDS-HT/JHS populations in Belgium, the Netherlands, Sweden, and Italy. Focus groups identified factors associated with: negative past physical therapy experiences, iatrogenic joint injuries, positive treatment experiences, and unmet rehabilitation needs. This group of EDS-HT/JHS patients has significant decrements in HRQoL and many unmet treatment needs, as well as a risk for iatrogenic injuries. We identify several approaches to help meet patients' needs and improve joint rehabilitation in patients with EDS-HT/JHS. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

After studying associations between variables assessed, hierarchical regression analyses were performed to identify HRQOL predictors.ResultsHRQOL Physical Health Component (SF-36 was predicted by perceived stress and depression, above and beyond demographic and clinical factors. And HRQOL Mental Health Component (SF-36 was predicted by education, time elapsed since diagnosis of breast cancer, time hospitalized during the past year, perceived stress and depression.ConclusionResults suggest that psychological variables may have a significant role for HRQOL prediction, and need to be taken into account along with demographic and clinical markers in order to explain HRQOL outcomes in women with breast cancer.

Understanding the relationship between the EQ-5D, SF-6D, HAQ and disease activity in inflammatory arthritis.

Adams, Roisin

2012-02-01

BACKGROUND: The growth of economic analyses and in particular cost-utility analyses (CUA), which use the QALY as a measure of outcome, has heightened the interest in the methodologies used to calculate the QALY. The EQ-5D has produced quite different utility values from that of the SF-6D. This article seeks to understand these differences using a cohort of patients with inflammatory arthritis. OBJECTIVE: To examine the relationship between the disease-specific measure, Health Assessment Questionnaire (HAQ) disability index (DI) and the preference-based measures, SF-6D, EQ-5D and European League Against Arthritis (EULAR) Disease Activity Score (DAS) in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA). METHODS: Patients with RA and PsA (n = 504) attending a tertiary rheumatology referral centre completed the HAQ, SF-6D and the EQ-5D before starting biological therapy and again 12 months later. The SF-36 was converted into a utility using the preference-based SF-6D. Clinical outcomes such as the DAS, joint counts and laboratory measures were also recorded. We calculated single index utility scores from the preference-based instruments using UK population norms. We used regression analysis to derive a mapping function and calculated utility scores from the HAQDI and the DAS 28. RESULTS: The mean utility observed at baseline for RA was 0.43 for the EQ-5D and 0.54 for the SF-6D and for PsA was 0.49 for the EQ-5D and 0.57 for the SF-6D. The utility gain demonstrated by the EQ-5D was over twice that of the SF-6D. The EQ-5D scored 17% of the RA group as less than 0 (state defined as worse than death); 7% of this group remained less than 0 at follow-up. The distribution of the utility estimates was similar for both RA and PsA. CONCLUSIONS: Our findings draw attention to the impact of states worse than death on the overall distribution for the EQ-5D derived utilities and how these impact on its use in practice. EQ-5D-derived QALY changes are over twice

For older adults receiving dialysis, health-related quality of life is not often considered in prognostication of death or future hospitalizations. To determine if routine health-related quality of life measures may be useful for prognostication, the objective of this study is to determine the extent of association of Kidney Disease Quality of Life (KDQOL-36) subscales with adverse outcomes in older adults receiving dialysis. This is a longitudinal study of 3500 adults aged ≥75 years receiving dialysis in the United States in 2012 and 2013. We used Cox and Fine and Gray models to evaluate the association of KDQOL-36 subscales with risk of death and hospitalization. We adjusted for sociodemographic variables, hemodialysis access type, laboratory values, and Charlson index. Three thousand one hundred thirty-two hemodialysis patients completed the KDQOL-36. From KDQOL-36 completion date in 2012, 880 (28.1%) died and 2023 (64.6%) had at least one hospitalization over a median follow-up of 512 and 203 days, respectively. Cohort members with a SF-12 physical component summary (PCS) in the lowest quintile had an increased adjusted risk of death [hazard ratio (HR), 1.55, 95% confidence interval (CI) 1.19-2.03] and hospitalization (HR, 1.29, 95% CI 1.09-1.54) compared with those with scores in the highest quintile. Cohort members with a SF-12 mental component summary in the lowest quintile had an increased risk of hospitalization (HR, 1.39, 95% CI 1.17-1.65) compared with those in the highest quintile. In adjusted analyses, there was no association between the symptoms of kidney disease, effects of kidney disease, and burden of kidney disease subscales with time to death or first hospitalization. Competing risk models showed similar HRs. Among the KDQOL-36 subscales, the SF-12 PCS demonstrates the strongest association with both death and future hospitalizations in older adults receiving hemodialysis Further research is needed to assess the value this subscale may add

Full Text Available Background: We aimed to develop and validate the Persian version of Short Form McGill Pain Questionnaire-2 (SF-MPQ-2 in patients with knee osteoarthritis. Methods: Translation and back translation was performed using Beaton’s guideline. After a consensus has achieved on the Persian version of SF-MPQ-2, it was administered to 30 patients with knee osteoarthritis in a pilot study. Then, we enrolled 100 patients with knee osteoarthritis to fill the final SF-MPQ-2 as well as SF-36 and WOMAC questionnaires. Forty-three patients returned 3 days after the initial visit to fill the Persian SF-MPQ-2 for the second time. Construct validity was tested by Pearson’s correlation coefficient between subscales of SF-MPQ-2 and subscales of SF-36 and WOMAC. Internal consistency for total and subscales was calculated by Cronbach’s alpha and reliability between test retest was performed using Intraclass correlation coefficient (ICC.

Background: We aimed to develop and validate the Persian version of Short Form McGill Pain Questionnaire-2 (SF-MPQ-2 in patients with knee osteoarthritis. Methods: Translation and back translation was performed using Beaton’s guideline. After a consensus has achieved on the Persian version of SF-MPQ-2, it was administered to 30 patients with knee osteoarthritis in a pilot study. Then, we enrolled 100 patients with knee osteoarthritis to fill the final SF-MPQ-2 as well as SF-36 and WOMAC questionnaires. Forty-three patients returned 3 days after the initial visit to fill the Persian SF-MPQ-2 for the second time. Construct validity was tested by Pearson’s correlation coefficient between subscales of SF-MPQ-2 and subscales of SF-36 and WOMAC. Internal consistency for total and subscales was calculated by Cronbach’s alpha and reliability between test retest was performed using Intraclass correlation coefficient (ICC. Results: ICC for subscales of SF-MPQ-2 ranged from 0.73 to 0.90. The ICC for total SF-MPQ-2 was 0.90. Cronbach’s alpha for subscales was 0.65-0.74 at the first visit and 0.58-0.81 at the second visit.

Full Text Available This paper attempts to give a general outline of the phenomenon of well­known American writer and philosopher Ayn Rand in contemporary social and ethical space. Application to the research of life, literary and philosophical heritage of the writer makes it possible to assess its impact on the current situation in politics and philosophy. Review of Ayn Rand’s artistic positions confirms her role as a landmark figure, who represented at that time the actual socio­cultural request of active man in contemporary philosophy and politics, “putting down” in literary form complex of philosophical questions to the level of the ordinary man. Ayn Rand is the focus of the social practices in which she was formed, lived and worked. The ideas of almost all philosophical subjects are presented in her works in a simple way, but they are fundamentally different from conventional notions of ethics, politics and philosophy in general, even the ideas of philosophers, whom she honored, such as Aristotle. That’s why modern philosophers are interested in studying her works now. After all, still there has no comprehensive academic analysis of her philosophical and scientific works of art.

Full Text Available Abstract Background Health-state utilities for prisoners have not been described. Methods We used data from a 1996 cross-sectional survey of Australian prisoners (n = 734. Respondent-level SF-36 data was transformed into utility scores by both the SF-6D and Nichol's method. Socio-demographic and clinical predictors of SF-6D utility were assessed in univariate analyses and a multivariate general linear model. Results The overall mean SF-6D utility was 0.725 (SD 0.119. When subdivided by various medical conditions, prisoner SF-6D utilities ranged from 0.620 for angina to 0.764 for those with none/mild depressive symptoms. Utilities derived by the Nichol's method were higher than SF-6D scores, often by more than 0.1. In multivariate analysis, significant independent predictors of worse utility included female gender, increasing age, increasing number of comorbidities and more severe depressive symptoms. Conclusion The utilities presented may prove useful for future economic and decision models evaluating prison-based health programs.

However, whether benefits from the improved HRQoL that occurs after antiviral treatment or drug discontinuation outweigh the risks of viral relapse is an unanswered question. The aim of this study was to evaluate the HRQoL among patients with CHB during antiviral treatment and withdrawal of treatment. Patients and methods: There were 102 patients who met the enrollment criteria with 54 patients in the treatment group and 48 patients in the discontinuation group. Sociodemographic information was collected. The 36-Item Short-Form Health Survey (SF-36, European Quality of Life-5 Dimensions, and Beck Depression Inventory (BDI were adopted to evaluate life quality and mental health. Results: In the treatment group, SF-36 showed that the physical functions were significantly increased. In the discontination group, the psychological functions showed improvement. A multivariate regression analysis indicated that baseline SF-36 score was a predictor for improvement in HRQoL (odds ratio =1.17, P=0.003 and baseline BDI score was a factor for remission of depression (odds ratio =0.75, P=0.005 after medical intervention. When the cutoff value of SF-36 score was set at 79.5, the sensitivity and specificity to predict improvement in HRQoL were 82.8% and 74.0%, respectively. When the cutoff value of BDI was found as 8.5, the sensitivity and specificity to predict

This study investigates the relationship between effort-reward-imbalance (ERI) at work and self-rated health (SF-36) among 941 Las Vegas hotel room cleaners (99% female, 84% immigrant). Logistic regression models adjust for age, health behaviors, physical workload and other potential confounders. 50% reported ERI and 60% poor or fair general health. Significant associations were found between ERI and all SF-36 health measures. Workers in the upper quartile of the efforts/rewards ratio were 2-5 times more likely to experience poor or fair general health, low physical function, high levels of pain, fatigue, and role limitations due to physical and mental health problems. The cross-sectional design limits causal interpretation of these associations. However, the development of interventions to reduce ERI and to improve general health among room cleaners deserves high priority considering that both high ERI and low self-rated health have predicted chronic diseases and mortality in prospective studies.

Superfamily 1 and Superfamily 2 helicases, two of the largest helicase protein families, play vital roles in many biological processes including replication, transcription and translation. Study of helicase proteins in the model microorganisms of archaea have largely contributed to the understanding of their function, architecture and assembly. Based on a large phylogenomics approach, we have identified and classified all SF1 and SF2 protein families in ninety five sequenced archaea genomes. Here we developed an online webserver linked to a specialized protein database named ARCPHdb to provide access for SF1 and SF2 helicase families from archaea. ARCPHdb was implemented using MySQL relational database. Web interfaces were developed using Netbeans. Data were stored according to UniProt accession numbers, NCBI Ref Seq ID, PDB IDs and Entrez Databases. A user-friendly interactive web interface has been developed to browse, search and download archaeal helicase protein sequences, their available 3D structure models, and related documentation available in the literature provided by ARCPHdb. The database provides direct links to matching external databases. The ARCPHdb is the first online database to compile all protein information on SF1 and SF2 helicase from archaea in one platform. This database provides essential resource information for all researchers interested in the field. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Mark E Lemstra,1 Marla R Rogers,21Alliance Health, Moose Jaw, 2Department of Physical Medicine and Rehabilitation, College of Medicine, University of Saskatchewan, Saskatoon, SK, Canada Abstract: When evaluating any health intervention, it is critical to include the impact of the intervention on health-related quality of life (HRQL. Among those who are obese, HRQL is often lower than the general population and even more when considering obesity-related comorbidities and bodily pain. The objectives of this paper were to determine the impact of a multidisciplinary, community-based obesity reduction program on HRQL and to determine the independent risk factors for lack of improvement from baseline to follow-up. HRQL was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36 at baseline and follow-up (24 weeks. To date, 84.5% of those who completed the program had improvements in their overall SF-36 score. Significant increases in the mean scores on eight dimensions of health were also observed. Lack of improvement was independently affected by smoking status (odds ratio 3.75; 95% confidence interval 1.44–9.78; P=0.007 and not having a buddy to attend the program (odds ratio 3.70; 95% confidence interval 1.28–10.68; P=0.015. Obesity reduction programs that target increasing exercise, improving diet, and cognitive behavioral therapy can positively impact HRQL in obese adults. Social support has a strong role to play in improving outcomes. Keywords: obesity, health-related quality of life, social- support, SF-36, Canada

Purpose: To evaluate the health-related quality of life (HR-QOL) of nasopharyngeal cancer (NPC) patients with cancer-free survival after treatment and to investigate the factors correlated with their HR-QOL. Methods and Materials: One hundred eighty-two NPC patients with cancer-free survival of more than 2 years after treatment were enrolled in the study. Data from the same number of people without a history of cancer, who had come to the hospital for health checkups, were also collected for comparison. The Chinese SF-36 questionnaire and nine items about head-and-neck functional impairments (HNFI) were self-reported by all participants at the clinics. Data relating to sociodemographic factors, cancer stage, and treatment of NPC survivors were analyzed. Results: Psychometric tests revealed the excellent internal reliability (Cronbach's α: 0.87-0.96) and discriminative validity of the Chinese SF-36 used in Taiwan. Most functional domains of the Chinese SF-36 and all nine HNFI items were significantly worse in NPC survivors than in control subjects. No cancer or treatment-related variables significantly correlated with any functional domains of SF-36 or any items of HNFI for NPC survivors. Economic status, educational level, occupational status, and the number of comorbidities were the variables that significantly correlated with most functional domains of SF-36 for NPC survivors. Patients with more sufficient economic status, higher educational levels, with employment, or without comorbidity tended to enjoy better HR-QOL as detected by the SF-36. Salivation, hearing, and swallowing dysfunctions were the top three HNFI that disturbed NPC survivors. Economic status remained the most significant variable correlated with HNFI, including salivation, swallowing, neck stiffness, taste, and phonation. Survivors with better economic status reported less severe HNFI. Conclusions: NPC survivors had worse HR-QOL than healthy control subjects in the study. Socioeconomic status

Rationale Health-related quality of life (HRQL) is impaired among patients with interstitial lung disease (ILD). Little is understood about HRQL in specific subtypes of ILD. Objectives The aim of this study was to characterize and identify clinical determinants of HRQL among patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and compare them to patients with idiopathic pulmonary fibrosis (IPF). Methods We identified patients with a diagnosis of RA-ILD and IPF from an ongoing longitudinal cohort of ILD patients. HRQL was measured at their baseline visit using the Short Form Health Survey (SF-36), versions 1 and 2. Regression models were used to characterize and understand the relationship between selected baseline clinical covariates, the physical component score (PCS) and mental component score (MCS) of the SF-36. Measurements and Main Results RA-ILD patients (n=50) were more likely to be younger and female compared to IPF patients (n=50). After controlling for age and pulmonary function, RA-ILD patients had a lower HRQL compared to IPF patients, as measured by the PCS (P=0.03), with significant differences in two of four PCS domains – bodily pain (P<0.01) and general health (P=0.01). Clinical covariates most strongly associated with a lower PCS in RA-ILD patients compared to IPF patients were the presence of joint pain or stiffness and dyspnea severity (P<0.01). Mental and emotional health, as measured by the MCS, was similar between RA-ILD and IPF patients. Conclusion The physical components of HRQL appear worse in RA-ILD patients compared to IPF patients as measured by the PCS of the SF-36. Differences in the PCS of the SF-36 can be explained in part by dyspnea severity and joint symptoms among patients with RA-ILD. PMID:28502413

Nonalcoholic fatty liver disease (NAFLD) is the most common form of liver disease. To elucidate the molecular basis of NAFLD, we performed an exome-wide association study of liver fat content. Three variants were associated with higher liver fat levels at the exome-wide significance level of 3.......6 × 10(-7): two in PNPLA3, an established locus for NAFLD, and one (encoding p.Glu167Lys) in TM6SF2, a gene of unknown function. The TM6SF2 variant encoding p.Glu167Lys was also associated with higher circulating levels of alanine transaminase, a marker of liver injury, and with lower levels of low...... knockdown of Tm6sf2 in mice increased liver triglyceride content by threefold and decreased very-low-density lipoprotein (VLDL) secretion by 50%. Taken together, these data indicate that TM6SF2 activity is required for normal VLDL secretion and that impaired TM6SF2 function causally contributes to NAFLD....

The Short Form-36 (SF-36) questionnaire is a valuable and easy-to-use tool for the measurement of quality of life in patients with obesity. To become a widely used tool, the questionnaire must be validated in many different contexts. Thus, the present study aimed to evaluate the construct validity and reliability of the SF-36 questionnaire among patients with obesity in Bahrain. The 36-item questionnaire was administered to a study cohort scheduled to undergo bariatric surgery at the Bahrain Defence Force Hospital in Bahrain. Demographic data were extracted. Principal component analysis was used to extract component factors. Factor analysis was used to determine construct validity and fit. The Cronbach's alpha value of the extracted factors was used to determine the internal consistency reliability. Statistical analyses were performed using SPSS version 19.0 and IBM AMOS version 22.0. Most of the participants were female with a mean body mass index (BMI) of 43.24 kg/m 2 . A six-factor solution explaining 52.31% of variance was generated. The global fit parameter estimates indicated that the suggested model exhibited an acceptable-to-good fit. Overall, the internal consistency reliability estimate of the SF-36 questionnaire was greater than 0.70. The identified six-factor model of the SF-36 questionnaire is a valuable tool for the measurement of quality of life among patients with obesity in Bahrain.

Several spacecraft missions have recently targeted asteroids to study their morphologies and physical properties (e.g. Galileo, NEAR Shoemaker), and more are planned. MUSES-C is a Japanese mission designed to rendezvous with a near-Earth asteroid (NEA). The MUSES-C spacecraft, Hayabusa, was launched successfully in May 2003. It will rendezvous with its target asteroid in 2005, and return samples to the Earth in 2007. Its target, 25143 Itokawa (1998 SF36), made a close approach to the Earth in 2001. We collected an extensive ground-based database of broadband photometry obtained during this time, which maximized the phase angle coverage, to characterize this target in preparation for the mission. Our project was designed to capitalize on the broadband UBVRI photometric observations taken with a series of telescopes, instrumentation, and observers. Photometry and spectrophotometry of Itokawa were acquired at Lowell, McDonald, Steward, Palomar, Table Mountain and Kiso Observatories. The photometric data sets were combined to calculate Hapke model parameters of the surface material of Itokawa, and examine the solar-corrected broadband color characteristics of the asteroid. Broadband photometry of an object can be used to: (1) determine its colors and thereby contribute to the understanding of its surface composition and taxonomic class, and (2) infer global physical surface properties of the target body. We present both colors from UBVRI observations of the MUSES-C target Itokawa, and physical properties derived by applying a Hapke model to the broadband BVRI photometry.

Background. The treatment of chronic inflammatory bowel disease (IBD) is costly, and limited resources call for analyses of the cost effectiveness of therapeutic interventions. The present study evaluated the equivalency of the Short Form 6D (SF-6D) and the Euro QoL (EQ-5D), two preference-based HRQoL instruments that are broadly used in cost-effectiveness analyses, in an unselected IBD patient population. Methods. IBD patients from seven European countries were invited to a follow-up visit ten years after their initial diagnosis. Clinical and demographic data were assessed, and the Short Form 36 (SF-36) was employed. Utility scores were obtained by calculating the SF-6D index values from the SF-36 data for comparison with the scores obtained with the EQ-5D questionnaire. Results. The SF-6D and EQ-5D provided good sensitivities for detecting disease activity-dependent utility differences. However, the single-measure intraclass correlation coefficient was 0.58, and the Bland-Altman plot indicated numerous values beyond the limits of agreement. Conclusions. There was poor agreement between the measures retrieved from the EQ-5D and the SF-6D utility instruments. Although both instruments may provide good sensitivity for the detection of disease activity-dependent utility differences, the instruments cannot be used interchangeably. Cost-utility analyses performed with only one utility instrument must be interpreted with caution.

Study Design An in vivo study of intervertebral disc degeneration using quantitative MRI and MRS. Objective To quantify water and proteoglycan (PG) content in the intervertebral disc using in vivo magnetic resonance spectroscopy (MRS), and to evaluate the relationship between MRS- quantified water/PG content, T1ρ, Pfirrmann score, clinical self-assessment, and discography. Summary of Background Data Previous in vitro studies have investigated the relationship between MRS-quantified water/PG content, and degenerative grade using cadaveric intervertebral discs. T1ρ has been shown to relate to Pfirmann grade and clinical self-assessment. However, the associations between MRS-quantified water/PG content, MR imaging-based T1ρ, self-assessment of health status and clinical response to discography have not been studied in vivo. Methods MRS and MR imaging were performed in 26 patients (70 discs) with symptomatic intervertebral degenerative disc (IVDD) and 23 controls (41 discs). Patients underwent evaluation of intervertebral discs with provocative discography. All subjects completed the SF-36 Health Survey and Oswestry Disability Index questionnaires. Results The water/PG peak area ratio was significantly elevated in a) patients (compared to controls) and in b) discs with positive discography (compared to negative discography). MR T1ρ exhibited similar trends. A significant association was found between T1ρ and normalized PG content (R2 = 0.61, p 0.05). The water/PG peak area ratio, normalized water, normalized PG, and Pfirrmann grade were significantly associated with patient self-assessment of disability and physical composite score, while disc height was not. Conclusion This study demonstrated a relationship between in vivo MRS spectroscopy (water content, PG content), imaging parameters (T1ρ, Pfirrmann Grade), discography results, and clinical self-assessment, suggesting that MRS-quantified water, PG and MR T1ρ relaxation time may potentially serve as

Major depressive disorder remains one of the leading causes of disability in developed countries despite pharmacological and psychological treatments. Patients with major depression have poorer health-related quality of life than persons of the general population, or patients with chronic somatic illness. Improvement of health-related quality of life in depression is thus a pertinent treatment objective. Both high-frequency repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex and low-frequency rTMS over the right dorsolateral prefrontal cortex have shown their effectiveness in medication-resistant depression. However, the Health-related Quality of Life questionnaire remains under-utilized to assess the effectiveness of rTMS in research or in a routine clinical setting. Our study aims to investigate in an open label trial the efficacy of low-frequency rTMS over the right dorsolateral prefrontal cortex on health-related quality of life and clinical outcomes in medication-resistant depression. In a naturalistic trial, 33 unipolar and bipolar patients with medication-resistant depression were treated with daily low-frequency rTMS over the right dorsolateral prefrontal cortex for 4 weeks. Health-related quality of life was assessed using the SF-36 questionnaire. The SF-36 is a generic, self-administered, and worldwide-used questionnaire, consisting of 36 items describing eight health dimensions: physical functioning, social functioning, role-physical problems, role-emotional problems, mental health, vitality, bodily pain, and general health. Physical component summary and mental component summary scores were then obtained. Depression severity was assessed using the 21-item self-report Beck Depression Inventory. Anxiety severity was assessed using the State-Trait Anxiety Inventory. The SF-36, the Beck Depression Inventory and the State-Trait Anxiety Inventory were assessed before and after low-frequency rTMS. The effect of r

Polycystic ovary syndrome (PCOS) is associated with reduced health-related quality of life (HRQOL) and increased prevalence of depressive and anxiety disorders. The impact of PCOS-specific treatments on these co-morbidities is unclear. To assess the impact of weight loss and decreasing hyperandrogenism on HRQOL and mood and anxiety disorders in women with PCOS. A secondary analysis of a randomized controlled trial (OWL-PCOS) of preconception treatment conducted at two academic centers in women (age, 18-40 years; body mass index, 27-42 kg/m(2)) with PCOS defined by Rotterdam criteria. Continuous oral contraceptive pill (OCP) or intensive lifestyle intervention or the combination (Combined) for 16 weeks. Changes in HRQOL assessed by PCOSQ and SF-36 and prevalence of depression and anxiety disorder assessed by PRIME-MD PHQ. The lowest scores were noted on the general health domain of the SF-36 and the weight and infertility domains on the PCOSQ. All three interventions resulted in significant improvement in the general health score on the SF-36. Both the OCP and Combined groups showed improvements in all domains of the PCOSQ (P symptoms, and anxiety disorders, and combined therapies offer further benefits in overweight/obese women with PCOS.

Full Text Available After validation of the widely used health-related quality of life (HRQOL generic measure, the Short Form 36 version 2 (SF-36v2, we investigated the HRQOL and associated factors of frontline railway workers in China. Ground workers, conductors, and train drivers were selected from Ankang Precinct by using a stratified cluster sampling technique. A total of 784 frontline railway workers participated in the survey. The reliability and validity of SF-36v2 was satisfactory. The physical component summary (PCS scores of three subgroups attained the average range for the USA general population, whereas the mental component summary (MCS scores were well below the range. Most domains scored below the norm, except for the physical functioning (PF domain. Among three subgroups, train drivers reported significantly lower scores on MCS and six health domains (excluding PF and bodily pain (BP. After controlled confounders, conductors had significantly higher PCS and MCS scores than ground workers. There is heterogeneity on risk factors among three subgroups, but having long or irregular working schedules was negatively associated with HRQOL in all subgroups. SF-36v2 is a reliable and valid HRQOL measurement in railway workers in China. The frontline railway workers’ physical health was comparative to American norms, whilst mental health was relatively worse. Long or irregular working schedules were the most important factors.

Full Text Available TM4SF1 is overexpressed in pancreatic ductal adenocarcinoma (PDAC and affects the development of this cancer. Also, multidrug resistance (MDR is generally associated with tumor chemoresistance in pancreatic cancer. However, the correlation between TM4SF1 and MDR remains unknown. This research aims to investigate the effect of TM4SF1 on gemcitabine resistance in PDAC and explore the possible molecular mechanism between TM4SF1 and MDR.The expression of TM4SF1 was evaluated in pancreatic cancer cell lines and human pancreatic duct epithelial (HPDE cell lines by quantitative RT-PCR. TM4SF1 siRNA transfection was carried out using Hiperfect transfection reagent to knock down TM4SF1. The transcripts were analyzed by quantitative RT-PCR, RT-PCR and western blotting for further study. The cell proliferation and apoptosis were obtained to investigate the sensitivity to gemcitabine of pancreatic cancer cells after silencing TM4SF1 in vitro. We demonstrated that cell signaling of TM4SF1 mediated chemoresistance in cancer cells by assessing the expression of multidrug resistance (MDR genes using quantitative RT-PCR. In vivo, we used orthotopic pancreatic tumor models to investigate the effect of proliferation after silencing TM4SF1 by a lentivirus-mediated shRNA in MIA PaCa-2 cell lines.The mRNA expression of TM4SF1 was higher in seven pancreatic cancer cell lines than in HPDE cell lines. In three gemcitabine-sensitive cell lines (L3.6pl, BxPC-3, SU86.86, the expression of TM4SF1 was lower than that in four gemcitabine-resistant cell lines (MIA PaCa-2, PANC-1, Hs766T, AsPC-1. We evaluated that TM4SF1 was a putative target for gemcitabine resistance in pancreatic cancer cells. Using AsPC-1, MIA PaCa-2 and PANC-1, we investigated that TM4SF1 silencing affected cell proliferation and increased the percentages of cell apoptosis mediated by treatment with gemcitabine compared with cells which were treated with negative control. This resistance was associated

To investigate the association between helplessness, disability, and disease activity with health-related quality of life (HRQoL) in a multiethnic cohort of rheumatoid arthritis (RA) patients in Singapore. This cross-sectional study was conducted at Tan Tock Seng Hospital, Department of Rheumatology, Allergy and Immunology, from October 2010 to October 2011. All patients fulfilled the American College of Rheumatology 1987 criteria for RA. Socio-demographics, clinical, and patient-reported outcome (PRO) variables were collected. HRQoL outcomes were Short Form 36 (SF-36) physical and mental component summary (PCS and MCS) scores and Short Form 6 Dimensions (SF-6D) utilities. Stepwise multiple linear regression analyses were performed using HRQoL outcomes as dependent variables in separate models and with adjustment for helplessness (Rheumatology Attitudes Index, RAI), disability (Health Assessment Questionnaire, HAQ), and disease activity (Disease Activity in 28 joints) followed by socio-demographic, clinical, and PRO variables. Complete data were provided by 473 consenting subjects [mean (SD) age: 60.02 (11.04) years, 85 % female, 77 % Chinese]. After adjustment for all measured covariates, only RAI and HAQ scores remained significantly associated with SF-36 MCS (β: -0.9, p < 0.001; β: -7.0, p < 0.001) and SF-6D utilities (β: -0.005, p < 0.001; β: -0.081, p < 0.001), respectively, while only HAQ scores were significantly associated with SF-36 PCS (β: -7.7, p < 0.001). Interventions to address the sense of helplessness and to prevent or reduce disability could improve HRQoL of RA patients.

The high emotional burden of physicians working in emergency departments may affect their quality of life perception. To evaluate health related quality of life among resident physicians performing shifts at an emergency department. Seventy one physicians aged 26,3 ± 1,7 years (47 women), working as residents in an emergency department, answered the short version of the Short-Form Health Survey Questionnaire (SF-36®). This questionnaire analyses eight domains: physical function, body pain, general health, vitality, social function, emotional role and mental health. Women had a significantly worse perception than a reference population in four dimensions of the SF-36, especially mental health and social functioning. Men had scores similar to the reference population. Among women, vitality is the best predictor of mental health and social functioning. Women working as residents in an emergency department have a worse perception of their quality of life than men performing the same job.

To assess the health-related quality of life (HRQOL) of immune thrombocytopenic purpura (ITP) patients. This was a cross-sectional, descriptive study comparing ITP patients' HRQOL to age and gender matched controls. ITP patients from the Platelet Disorder Support Association were recruited until 1000 surveys had been completed. Controls were randomly sampled from the Harris Interactive Online Panel. ITP patients and controls completed a one-time web-based survey, including a comprehensive HRQOL assessment. ITP patients completed the SF-36, the EQ-5D, and the ITP-Patient Assessment Questionnaire (ITP-PAQ). Controls completed the SF-36 and EQ-5D only. ITP patients' SF-36 and EQ-5D scores were compared to controls in unadjusted and adjusted analyses. Associations between splenectomy status, duration of illness, and platelet count with ITP patients' HRQOL scores were also examined. This analysis included 1002 ITP patients and 1031 controls. ITP patients scored worse on seven of eight SF-36 domains and the Physical and Mental Summary scores (all p PAQ scales: Bother, Psychological, Fear, Social Activity, and Work (all p PAQ scales. Lower platelet count was consistently associated with worse ITP-PAQ scores and had weaker associations with SF-36 and EQ-5D scores. ITP was associated with consistent and statistically significant deficits on generic HRQOL measures. The ITP-PAQ demonstrated differences based on disease severity and treatments. The self-selection bias in the two samples limits the generalizability of the results to all patients with ITP. Further research is needed in more generalizable samples.

There is growing interest in health related quality of life (HRQoL) as an outcome measure in international trials. However, there might be differences in the conceptualization of HRQoL across different socio-cultural groups. The objectives of current study were: (I) to compare HRQoL, measured with the short form (SF)-36 of Dutch and Chinese traumatic brain injury (TBI) patients 1 year after injury and; (II) to assess whether differences in SF-36 profiles could be explained by cultural differences in HRQoL conceptualization. TBI patients are of particular interest because this is an important cause of diverse impairments and disabilities in functional, physical, emotional, cognitive, and social domains that may drastically reduce HRQoL. A prospective cohort study on adult TBI patients in the Netherlands (RUBICS) and a retrospective cohort study in China were used to compare HRQoL 1 year post-injury. Differences on subscales were assessed with the Mann-Whitney U-test. The internal consistency, interscale correlations, item-internal consistency and item-discriminate validity of Dutch and Chinese SF-36 profiles were examined. Confirmatory factor analysis was performed to assess whether Dutch and Chinese data fitted the SF-36 two factor-model (physical and mental construct). Four hundred forty seven Dutch and 173 Chinese TBI patients were included. Dutch patients obtained significantly higher scores on role limitations due to emotional problems (p cultural differences in conceptualization, since item- and scale statistics were all sufficient. However, differences among Dutch and Chinese patients were found in the conceptualization of the domains vitality, mental health and social functioning. One year after TBI, Dutch and Chinese patients reported a different pattern of HRQoL. Further, there might be cultural differences in the conceptualization of some of the SF-36 subscales, which has implications for outcome evaluation in multi-national trials.

Falls are an important cause of morbidity in older adults. Equine-assisted activities including therapeutic riding (TR) benefit balance and neuromuscular control in patients with neurological disabilities but have not been systematically studied in older adults at greater risk for falls due to balance deficits. The effect of an 8-week TR program on measures of balance and quality of life in community-dwelling older adults with established balance deficits was evaluated. This was a pretest-post-test single-group trial of a TR program on measures of balance and quality of life. The study was conducted at a Professional Association of Therapeutic Horsemanship (PATH) International Premier riding center. The subjects comprised 9 adults (5 female, 4 males) with a mean age 76.4 years (range 71-83 years). This included an 8-week observation period followed by an 8-week TR program consisting of 1 hour per week of supervised horseback riding and an 8-week follow-up period. SUBJECTS received balance testing at weeks 0, 8, 16, and 24 using the Fullerton Advanced Balance Scale (FABS), and quality of life was measured at weeks 8 and 16 using the Rand SF (short form) 36 quality-of-life measure. OUTCOME MEASURES were change in the FABS and Rand SF 36. There was no significant difference in balance scores between the start and end of the observation period. There was a significant improvement in the balance score and perception of general health from the start to the end of the intervention period, and no significant difference between the end of the intervention and the end of study, suggesting that improvements may have been sustained. TR is a safe activity for older adults with mild to moderate balance deficits and leads to both improvements in balance and quality of life. Longer and larger studies to assess the benefit of equine-assisted activities on improvements in balance and reduction in fall risk are needed.

Full Text Available Background. The treatment of chronic inflammatory bowel disease (IBD is costly, and limited resources call for analyses of the cost effectiveness of therapeutic interventions. The present study evaluated the equivalency of the Short Form 6D (SF-6D and the Euro QoL (EQ-5D, two preference-based HRQoL instruments that are broadly used in cost-effectiveness analyses, in an unselected IBD patient population. Methods. IBD patients from seven European countries were invited to a follow-up visit ten years after their initial diagnosis. Clinical and demographic data were assessed, and the Short Form 36 (SF-36 was employed. Utility scores were obtained by calculating the SF-6D index values from the SF-36 data for comparison with the scores obtained with the EQ-5D questionnaire. Results. The SF-6D and EQ-5D provided good sensitivities for detecting disease activity-dependent utility differences. However, the single-measure intraclass correlation coefficient was 0.58, and the Bland-Altman plot indicated numerous values beyond the limits of agreement. Conclusions. There was poor agreement between the measures retrieved from the EQ-5D and the SF-6D utility instruments. Although both instruments may provide good sensitivity for the detection of disease activity-dependent utility differences, the instruments cannot be used interchangeably. Cost-utility analyses performed with only one utility instrument must be interpreted with caution.

Alzheimer's disease has a destructive drawbacks on the patient and his/her entire family as this disease badly af fects the behavior, cognition and abilities to do activities of daily living (ADL). The physical and mental benefits of exercise are widely known but seldom available to persons suffering from Alzheimer's disease. The aim of this study was to measure quality of life, systemic inflammation and psychological well-being response to aerobic exercises in Alzheimer's. Forty Alzheimer elderly subjects were enrolled in two groups; the first group received treadmill aerobic exercise, while the second group was considered as a control group and received no training intervention for two months. Assessment of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), Rosenberg Self-Esteem Scale (RSES),Beck Depression Inventory (BDI), Profile of Mood States(POMS) and SF-36 health quality of life (SF-36 HRQL) were taken before and at the end of the study. There was a 25.2%, 19.4%, 23.5%, 21.3%, 17.7% , 11.7%, 12.5% and 10.1 % reduction in mean values of TNF-α, IL-6, BDI, POMS, health transition SF-36 subscale, bodily pain SF-36 subscale, role functioning: emotional SF-36 subscale and mental health SF-36 subscale respectively in addition to 15.7%, 13.1%, 12.6%, 11.1%, 13.2% and 11.2 % increase in mean values of RSES, physical functioning SF-36 subscale, role functioning:physical SF-36 subscale, general health SF-36 subscale, Vitality SF-36 subscale and Social functioning SF-36 subscale respectively in group (A) received aerobic exercise training, so that there was a significant reduction in the mean values of TNF-α, IL-6, BDI & POMS and increase in the mean values of SF-36 HRQL subscale scores, RSES in group (A) as a result of aerobic exercise training, while the results of group (B) who received no training intervention were not significant. Also, there were significant differences between mean levels of the investigated parameters in group (A) and group (B) at

For their distinguished global warming potential (GWP100) and long atmosphere lifespan, CF 4 , SF 6 and SF 5 CF 3 were significant in the field of greenhouse gas research. The details of discharging character and the optimal parameter were discussed by using a Dielectric Barrier Discharge (DBD) reactor to decompose these potent greenhouse gases in this work. The results showed that SF 6 could be decomposed by 92% under the conditions of 5 min resident time and 3000 V applied voltage with the partial pressure of 2.0 kPa, 28.2 kPa, and 1.8 kPa for SF 6 , air and water vapor, respectively. 0.4 kPa CF 4 could be decomposed by 98.2% for 4 min resident time with 30 kPa Ar added. The decomposition of SF 5 CF 3 was much more effective than that of SF 6 and CF 4 and moreover, 1.3 kPa SF 5 CF 3 , discharged with 30 kPa O 2 , Ar and air, could not be detected when the resident time was 80 s, 40 s, and 120 s, respectively. All the results indicated that DBD was a feasible technique for the abatement of potent greenhouse gases. (paper)

Full Text Available Background. There is very little data describing the long-term health impacts of meditation. Aim. To compare the quality of life and functional health of long-term meditators to that of the normative population in Australia. Method. Using the SF-36 questionnaire and a Meditation Lifestyle Survey, we sampled 343 long-term Australian Sahaja Yoga meditation practitioners and compared their scores to those of the normative Australian population. Results. Six SF-36 subscales (bodily pain, general health, mental health, role limitation—emotional, social functioning, and vitality were significantly better in meditators compared to the national norms whereas two of the subscales (role limitation—physical, physical functioning were not significantly different. A substantial correlation between frequency of mental silence experience and the vitality, general health, and especially mental health subscales (P<0.005 was found. Conclusion. Long-term practitioners of Sahaja yoga meditation experience better functional health, especially mental health, compared to the general population. A relationship between functional health, especially mental health, and the frequency of meditative experience (mental silence exists that may be causal. Evidence for the potential role of this definition of meditation in enhancing quality of life, functional health and wellbeing is growing. Implications for primary mental health prevention are discussed.

To characterize health-related quality of life (HRQoL) in medical cannabis patients. Short Form 36 (SF-36) Physical Health Component Score and Mental Health Component Score (MCS) surveys as well has CDC (Centers for Disease Control) HRQoL-14 surveys were completed by 37 qualified patients. Mean SF-36 PCS and MCS, normalized at 50, were 37.4 and 44.2, respectively. Eighty percent of participants reported activity/functional limitations secondary to impairments or health problems. Patients reported using medical cannabis to treat a wide array of symptoms across multiple body systems with relief ratings consistently in the 7-10/10 range. The HRQoL results in this sample of medical cannabis-using patients are comparable with published norms in other chronically ill populations. Data presented provide insight into medical cannabis-using patients' self-rated health, HRQoL, disease incidences, and cannabis-related symptom relief.

Clinical studies use both disease-specific and generic health outcomes measures. Disease-specific measures focus on health domains most relevant to the clinical population, while generic measures assess overall health-related quality of life. There is little information about which domains of the Oswestry Disability Index (ODI) are most important in determining improvement in overall health-related quality of life, as measured by the 36-Item Short Form Health Survey (SF-36), after lumbar spinal fusion. The objective of the study is to determine which clinical elements assessed by the ODI most influence improvement of overall health-related quality of life. A single tertiary spine center database was used to identify patients undergoing lumbar fusion for standard degenerative indications. Patients with complete preoperative and 2-year outcomes measures were included. Pearson correlation was used to assess the relationship between improvement in each item of the ODI with improvement in the SF-36 physical component summary (PCS) score, as well as achievement of the SF-36 PCS minimum clinically important difference (MCID). Multivariate regression modeling was used to examine which items of the ODI best predicted achievement for the SF-36 PCS MCID. The effect size and standardized response mean were calculated for each of the items of the ODI. A total of 1104 patients met inclusion criteria (674 female and 430 male patients). The mean age at surgery was 57 years. All items of the ODI showed significant correlations with the change in SF-36 PCS score and achievement of MCID for the SF-36 PCS, but only pain intensity, walking, and social life had r values > 0.4 reflecting moderate correlation. These 3 variables were also the dimensions that were independent predictors of the SF-36 PCS, and they were the only dimensions that had effect sizes and standardized response means that were moderate to large. Of the health dimensions measured by the ODI, pain intensity, walking

Recent data reaffirm decreased health-related quality of life (HRQL) in obese adults and children. Health-related quality of life is markedly improved after bariatric surgery in adults. Little HRQL data are available in adolescents undergoing bariatric surgery. Sixteen patients (14-20 years old) underwent gastric bypass. Thirteen patients completed a general HRQL measure (Short Form 36 [SF-36]) before surgery. Of these, 9 completed the SF-36 again at various follow-up times, as well as a measure of weight-related quality of life (Impact of Weight on Quality of Life-Lite). Three patients completed postsurgical forms only. Data were analyzed using t test and analysis of variance. Results are reported as mean +/- SD. Mean age and body mass index at operation were 18.5 +/- 1.7 years and 54 +/- 7.6 kg/m(2). Postoperatively, patients lost an average of 66% +/- 29% excess weight over a mean follow-up of 17 +/- 12 (range, 1-39) months. Mean preoperative SF-36 physical component score was 34.7 +/- 10 and mental component score was 40.6 +/- 13.5 (adult population mean = 50.0 +/- 10 for each). At last follow-up, mean physical component score had increased to 55.5 +/- 5, and mental component score, to 55.2 +/- 8.6 (P < .0001). Adolescent Impact of Weight on Quality of Life-Lite scores after surgery did not differ from means for normal weight adults (93% +/- 7% vs 96% +/- 7%, P = .15). Health-related quality of life in adolescents and young adults undergoing bariatric surgery improves dramatically in early follow-up. Long-term data are needed to definitively study this surgical therapy for obesity in adolescents.

The electron drift velocity, electron energy distribution function (EEDF), density-normalized effective ionization coefficient and density-normalized longitudinal diffusion velocity are calculated in SF6-O2 and SF6-Air mixtures. The experimental results from a pulsed Townsend discharge are plotted for comparison with the numerical results. The reduced field strength varies from 40 Td to 500 Td (1 Townsend=10-17 V·cm2) and the SF6 concentration ranges from 10% to 100%. A Boltzmann equation associated with the two-term spherical harmonic expansion approximation is utilized to gain the swarm parameters in steady-state Townsend. Results show that the accuracy of the Boltzmann solution with a two-term expansion in calculating the electron drift velocity, electron energy distribution function, and density-normalized effective ionization coefficient is acceptable. The effective ionization coefficient presents a distinct relationship with the SF6 content in the mixtures. Moreover, the E/Ncr values in SF6-Air mixtures are higher than those in SF6-O2 mixtures and the calculated value E/Ncr in SF6-O2 and SF6-Air mixtures is lower than the measured value in SF6-N2. Parametric studies conducted on these parameters using the Boltzmann analysis offer substantial insight into the plasma physics, as well as a basis to explore the ozone generation process.

Deviation from normal weight is associated with health risks, but less is known about the association between weight and health-related quality of life (HRQOL). We investigated this in the context of a population-based study, using a standard five-category weight classification system based on body mass index (BMI). The Canadian Multicentre Osteoporosis Study is a randomly selected sample of men and women over 25 years of age from nine centres across Canada. Data were obtained by interview, and height and weight were measured and used to calculate BMI. HRQOL was measured using the SF-36. Multivariable linear regression was used to identify the association between BMI category and SF-36 scores after controlling for potential confounders. Complete data were available for 6,302 women and 2,792 men. Mean BMI for every age and gender group exceeded healthy weight guidelines. For women, being underweight, overweight or obese was associated with poorer HRQOL in most SF-36 outcomes while for men, this was associated with poorer HRQOL in some domains and with higher HRQOL in others. A significant proportion of the population may be putting their health at risk due to excess weight, which may have a substantial negative effect on HRQOL, particularly in women. This underscores the need for continued public health efforts aimed at combating overweight and obesity.

Catquest questionnaire was originally developed in Swedish to measure patients' self-assessed visual function to evaluate the benefit of cataract surgery. The result of the Rasch analysis leading to the creation of the nine-item short form of Catquest, (Catquest-9SF), and it had been translated and validated in English. The aim is therefore to evaluate the translated Catquest-9SF questionnaire in Malay and Chinese (Mandarin) language version for measuring patient-reported visual function among cataract population in Malaysia. The English version of Catquest-9SF questionnaire was translated and back translated into Malay and Chinese languages. The Malay and Chinese translated versions were self-administered by 236 and 202 pre-operative patients drawn from a cataract surgery waiting list, respectively. The translated Catquest-9SF data and its four response options were assessed for fit to the Rasch model. The Catquest-9SF performed well in the Malay and Chinese translated versions fulfilling all criteria for valid measurement, as demonstrated by Rasch analysis. Both versions of questionnaire had ordered response thresholds, with a good person separation (Malay 2.84; and Chinese 2.59) and patient separation reliability (Malay 0.89; Chinese 0.87). Targeting was 0.30 and -0.11 logits in Malay and Chinese versions respectively, indicating that the item difficulty was well suited to the visual abilities of the patients. All items fit a single overall construct (Malay infit range 0.85-1.26, outfit range 0.73-1.13; Chinese infit range 0.80-1.51, outfit range 0.71-1.36), unidimensional by principal components analysis, and was free of Differential Item Functioning (DIF). These results support the good overall functioning of the Catquest-9SF in patients with cataract. The translated questionnaire to Malay and Chinese-language versions are reliable and valid in measuring visual disability outcomes in the Malaysian cataract population.

To compare parameters of attention in healthy people and patients with neoplasms in different regions of the cerebral cortex and to evaluate quality of life (QoL) indices with regard to impairment of different attention systems. Twenty patients with oncological lesions of the brain (mean age 56.5±8.8 years) who did not undergo surgery were studied. Tumor localization was confirmed using contrast-enhanced computed tomography, the tumor type was histologically verified. A control group included 18 healthy people matched for age, sex and education level. To determine attention system functions, we developed a computed version of the Attention Network Test. Error rate and reaction time for correct responses to the target stimulus, displayed along with neutral, congruent and incongruent signals, were the indicators of the efficacy of selective processes. QoL indices were assessed using SF-36 health survey questionnaire. The readiness to respond to incoming stimuli was mostly impaired in patients with brain tumors. Efficacy of executive attention, assessed as the increase in the number of errors in selection of visual stimuli, was decreased while temporary parameters of the functions of this system were not changed in patients compared to controls. The SF-36 total score was stable in patients with marked reduction in scores on the Role and Emotional Functioning scales. The most severe health impairment measured on the SF-36 scales of role/social emotional functioning and viability was recorded in patients with the lesions of frontal cortical areas compared to temporal/parietal areas. The relationship between SF-36 Health self-rating and attention systems was found. This finding puts the question of the importance of attention characteristics and QoL for survival prognosis of patients with brain tumors.

Full Text Available Abstract Background Measuring health-related quality of life (HRQOL is important in arthritis and the SF-36v2 is the current state-of-the-art. It is only emerging how well the Centers for Disease Control and Prevention (CDC HRQOL measures HRQOL for people with arthritis. This study's purpose is to assess the psychometric properties of the 9-item CDC HRQOL (4-item Healthy Days Core Module and 5-item Healthy Days Symptoms Module in an arthritis sample using the SF-36v2 as a comparison. Methods In Fall 2002, a cross-sectional study acquired survey data including the CDC HRQOL and SF-36v2 from 2 North Carolina populations of adult patients reporting osteoarthritis, rheumatoid arthritis, and fibromyalgia; 2182 (52% responded. The first item of both the CDC HRQOL and the SF-36v2 was general health (GEN. All 8 other CDC HRQOL items ask for the number of days in the past 30 days that respondents experienced various aspects of HRQOL. Exploratory principal components analyses (PCA were conducted on each sample and the combined samples of the CDC HRQOL. The multitrait-multimethod matrix (MTMM was used to compute correlations between each trait (physical health and mental health and between each method of measurement (CDC HRQOL and SF36v2. The relative contribution of the CDC HRQOL in predicting the physical component summary (PCS and the mental component summary (MCS was determined by regressing the CDC HRQOL items on the PCS and MCS scales. Results All 9 CDC HRQOL items loaded primarily onto 1 factor (explaining 57% of the item variance representing a reasonable solution for capturing overall HRQOL. After rotation a 2 factor interpretation for the 9 items was clear, with 4 items capturing physical health (physical, activity, pain, and energy days and 3 items capturing mental health (mental, depression, and anxiety days. All of the loadings for these two factors were greater than 0.70. The CDC HRQOL physical health factor correlated with PCS (r = -.78, p 2

Full Text Available Background/Aim. With the improvement of the outcomes after liver transplantation (LTx, health-related quality of life (HRQoL and physical activity are becoming significant outcome parameters. We prospectively assessed these parameters in patients with autoimmune and nonautoimmune liver disorders undergoing LTx. Materials and Methods. Patients (n=107 were subdivided into 3 groups depending on the time after LTx: group-A (n=21: 6–12 months; group-B (n=48: 13–36 months; and group-C (n=38: >37 months. SF-36 and IPAQ were applied in HRQoL and physical activity assessment. Results. Females had impaired HRQoL in most SF-36 domains. Younger patients showed higher scores at SF-36 physical functioning domain but IPAQ was not influenced by age. Group-B had higher general health and physical component summary than group-A (P=0.037, P=0.04, resp. and total IPAQ than group-C (P=0.047. The sitting time domain was longer in group-A than in group-B and group-C (P=0.0157;  P=0.042, resp.. Employed patients had better HRQoL and higher physical activity than those not working. SF-36 and IPAQ were unrelated to the autoimmune etiology of liver disease. Conclusions. These findings show that female and unemployed patients have worse HRQoL, while gender and age at LTx time do not affect IPAQ’s physical activity. The autoimmune etiology of liver disease does not influence HRQoL and physical activity after LTx.

We tried to evaluate the association of self-leadership, effective health behaviors, and posttraumatic growth with health-related quality of life (HRQOL). We recruited survivors of cancer from seven hospitals in Korea between 2011 and 2012. The patients completed the Seven Habits Profile (7HP) to evaluate leadership competency, the 10 rules for highly effective health behavior to evaluate health behavior, the Posttraumatic Growth Inventory (PTGI) to evaluate posttraumatic growth, the Short Form 36 (SF-36) to evaluate HRQOL, and the Hospital Anxiety and Depression Scale (HADS) to evaluate anxiety and depression. We performed multiple logistic regressions to identify significant associations. A total of 668 patients with cancer participated in the study. Patients who scored high on the leadership subscales of Be Proactive, Begin with the End in Mind, Put First Things First, Think Win-Win, Synergize, and Sharpen the Saw in 7HP tried to practice and keep their health behaviors more. The Begin with the End in Mind, Put First Things First, Synergize, and Sharpen the Saw subscales of the 7HP were also significantly correlated with subscales on the PTGI. Patients who scored high on the leadership subscales of Life Balance, Be Proactive, Begin with the End in Mind, Think Win-Win, and Sharpen the Saw had higher physical and mental component scale scores on the SF-36 and lower anxiety and depression subscale scores on the HADS. Self-leadership, health behaviors, and posttraumatic growth are associated with QOL in survivors of cancer. Copyright © 2014 John Wiley & Sons, Ltd.

To examine subjective health-related quality of life (HRQoL) in adults with congenital unilateral upper limb deficiency (UULD) in Norway and to explore the associations between demographic and clinical factors and HRQoL. Cross-sectional study comparing HRQoL, measured by SF-36, among adults with UULD and an age- and gender-matched control group from the Norwegian general population (NGP). Seventy-seven respondents, median age 42 years (range: 20-82); 71% were women. Most had left-sided (61%), below elbow (53%), transverse (73%) deficiency. Compared to the NGP, the UULD group reported reduced HRQoL on all SF-36 subscales except for the role emotional (RE) scale (p=0.321), mental health (MH) (p=0.055) and mental component summary (MCS) (p=0.064). The greatest difference was on the bodily pain (BP) scale (point difference of 20.0). Multiple linear regression models showed significant association between several physical- and mental SF-36 subscales and occupational status, occurrence of comorbidity and chronic pain. Persons with UULD reported reduced HRQoL on most SF-36 subscales, mostly in the physical health domain. Employment status, occurrence of comorbidity and chronic pain seem to have a negative impact on the HRQoL. Measures that can reduce pain and loss of function should be given particular attention in UULD rehabilitation. Implications for Rehabilitation Persons with congenital unilateral upper limb deficiency (UULD) who experience pain and discomfort should seek professional help for evaluating their everyday coping strategies. Professionals who meet persons with UULD should examine anomalies, comorbidity, pain and employment status before choosing advices and actions. Individually adapted grip-improving devices, environments, physical exercise and pain management programs should be implemented early to reduce pain, loss of function and decreased HRQoL. A multidisciplinary approach is often necessary when counseling persons with UULD.

OBJECTIVE: Increased levels of depressive symptoms, fatigue or pain (all dimensions of reduced health-related quality of life (HRQOL)) are common in people with type 2 diabetes mellitus (DM). Earlier studies have reported associations between low vitamin D status and fatigue and depressive symptoms...... with type 2 DM derived from general practices. HRQOL at baseline and after six months using the Short Form 36 Health Survey (SF-36) was collected. Linear regression analyses were used to compare the change in HRQOL over time between the vitamin D and placebo group. RESULTS: 187/275 (68%) completed baseline...... both groups was seen concerning the SF-36 domain role limitations due to physical problems in disadvantage of the vitamin D group. CONCLUSIONS: Six months of vitamin D supplementation did not improve HRQOL in non-vitamin D-deficient people with type 2 DM managed on oral antidiabetic therapy....

Factors promoting health-related quality of life in people with rheumatic diseases: a 12 month longitudinal study

Science.gov (United States)

2011-01-01

Background Rheumatic diseases have a significant adverse impact on the individual from physical, mental and social aspects, resulting in a low health-related quality of life (HRQL). There is a lack of longitudinal studies on HRQL in people with rheumatic diseases that focus on factors promoting HRQL instead of risk factors. The aim of this study was to investigate the associations between suggested health promoting factors at baseline and outcome in HRQL at a 12 month follow-up in people with rheumatic diseases. Methods A longitudinal cohort study was conducted in 185 individuals with rheumatic diseases with questionnaires one week and 12 months after rehabilitation in a Swedish rheumatology clinic. HRQL was assessed by SF-36 together with suggested health factors. The associations between SF-36 subscales and the health factors were analysed by multivariable logistic regressions. Results Factors predicting better outcome in HRQL in one or several SF-36 subscales were being younger or middle-aged, feeling painless, having good sleep structure, feeling rested after sleep, performing low effort of exercise more than twice per week, having strong sense of coherence (SOC), emotional support and practical assistance, higher educational level and work capacity. The most important factors were having strong SOC, feeling rested after sleep, having work capacity, being younger or middle-aged, and having good sleep structure. Conclusions This study identified several factors that promoted a good outcome in HRQL to people with rheumatic diseases. These health factors could be important to address in clinical work with rheumatic diseases in order to optimise treatment strategies. PMID:21599884

Transmembrane-4 L-six family member-1 (TM4SF1) is a small plasma membrane-associated glycoprotein that is highly and selectively expressed on the plasma membranes of tumor cells, cultured endothelial cells, and, in vivo, on tumor-associated endothelium. Immunofluorescence microscopy also demonstrated TM4SF1 in cytoplasm and, tentatively, within nuclei. With monoclonal antibody 8G4, and the finer resolution afforded by immuno-nanogold transmission electron microscopy, we now demonstrate TM4SF1 in uncoated cytoplasmic vesicles, nuclear pores and nucleoplasm. Because of its prominent surface location on tumor cells and tumor-associated endothelium, TM4SF1 has potential as a dual therapeutic target using an antibody drug conjugate (ADC) approach. For ADC to be successful, antibodies reacting with cell surface antigens must be internalized for delivery of associated toxins to intracellular targets. We now report that 8G4 is efficiently taken up into cultured endothelial cells by uncoated vesicles in a dynamin-dependent, clathrin-independent manner. It is then transported along microtubules through the cytoplasm and passes through nuclear pores into the nucleus. These findings validate TM4SF1 as an attractive candidate for cancer therapy with antibody-bound toxins that have the capacity to react with either cytoplasmic or nuclear targets in tumor cells or tumor-associated vascular endothelium. - Highlights: • Anti-TM4SF1 antibody 8G4 was efficiently taken up by cultured endothelial cells. • TM4SF1–8G4 internalization is dynamin-dependent but clathrin-independent. • TM4SF1–8G4 complexes internalize along microtubules to reach the perinuclear region. • Internalized TM4SF1–8G4 complexes pass through nuclear pores into the nucleus. • TM4SF1 is an attractive candidate for ADC cancer therapy

Matthew Ocran

2010-09-01

Full Text Available This paper seeks to examine the dynamic causal relations between the two major financial assets, stock prices of the US and South Africa and the rand/US$ exchange rate. The study uses a mixed bag of time series approaches such as cointegration, Granger causality, impulse response functions and forecasting error variance decompositions.  The paper identifies a bi-directional causality from the Standard & Poor’s 500 stock price index to the rand/US$ exchange rate in the Granger sense. It was also found that the Standard & Poor’s stock price index accounts for a significant portion of the variations in the Johannesburg Stock Exchange’s All Share index. Thus, while causality in the Granger sense could not be established for the relationship between the price indices of the two stock exchanges it can argued that there is some relationship between them. The results of the study have implications for both business and Government.

Lumbar discectomy is among the most frequently performed procedures in spinal surgery. Transforaminal percutaneous endoscopic discectomy (TPED) is a minimally invasive technique that gains ground among surgeons in the recent years. TPED has been studied in terms of effectiveness, however little is known about its overall impact on health-related quality of life (HRQoL) of the patients. To investigate the progress of HRQoL following TPED. Seventy-six (76) patients were enrolled in the study. Mean age was 56.5 ±12.1 years with 38 (50%) males and 38 (50%) females. All patients underwent TPED at L3-L4 (27.6%), L4-L5 (52.6%) and L5-S1 (19.7%). SF-36 was used for the assessment of HRQoL preoperatively and at 6 weeks, at 3, 6 and 12 months after the procedure. All aspects of SF-36 questionnaire showed statistically significant improvement one year after the procedure (p< 0.001). Role limitations due to physical problems, bodily pain and role limitations due emotional problems showed the highest improvement, followed by physical functioning, vitality, social functioning, mental health and general health. TPED for lumbar disc herniation is associated with significant improvement in all aspects of health-related quality of life within 6 weeks postoperatively and the improvement remains significant one year after surgery, as measured by the SF-36 questionnaire.

To assess health-related quality of life (HRQOL) and to describe factors associated with its variation among undergraduate medical students at a Brazilian private medical school. A cross-sectional study in a sample (n=180) of medical students at a private medical school in Salvador, Brazil, stratified by year of medical course. Data about age, sex, year of course, physical activity, sleepiness, headaches, participation in a student loan program supported by the Brazilian government (FIES) and living arrangements were collected using a self-administered form. HRQOL was assessed by using a Brazilian Portuguese version of the SF-36 form. The eight domains of SF-36 and the Physical Component (PCS) and Mental Component (MCS) Summaries scales were calculated. The medical students showed poor HRQOL, mainly because of the mental component. Lower mean scores were found among those with FIES support, females, those suffering from sleepiness, headaches and lacking physical activity. No clear trend was observed in the variation of the SF-36 mean scores according to the year of medical school. However, students in the fifth year of the course had the highest HRQOL mean scores. Health-related quality of life of students at this private medical school was poor, mainly because of its mental component. Lower HRQOL was associated with FIES support, females, sleepiness, headaches and lack of regular physical activity. Higher scores were found among fifth year students.

To analyse the differences in the self-estimate of life quality depending on the ageing type - passive, active. Life-quality linked to health was measured with an SF-36 survey, which gives multi-dimensional criteria of health and life-quality. SF-36 survey represents a theoretically based and empirically proven operationalization of two overal health concepts, which are body and mental health, and its two general manifestations, functioning, and welfare. 200 examinees in total, aged from 55 to 92, were included in the research. Divided by sex, in the research participated 148 women and 52 men. Depending on the ageing way, the examinees were divided into 2 categories: passive ageing (n=100), active ageing (n=100), and for these groups a detailed result analysis was done. Statistical analysis includes descriptive statistics, Hi-square test, Spearman's correlation coefficient, and Mann-Whitney U test. In all dimensions of health, examinees from the category Active ageing achieve higher scores, which indicates better health and better functioning. Between the groups, a statistically significant difference was determined, on the following dimensions: Overall health, Pains, Energy and vitality, Social operations, and Limits due to emotional difficulties. With the Hi-square test, it was determined that there are differences between the groups. The biggest difference can be seen in the reply categories related to health deterioration (χ 2 =10.391; df=4; p=0.034). Examinees from the Active ageing group mention significantly less that their health has gotten worse compared to the previous year (26% of the active ones state that their health is somewhat worse, and only 2% that their health is significantly worse, compared to the passive ones where 36% state that their health is worse, and 9% that it's much worse compared to the year before). Tested was the difference between arithmetic middles on the issue of mental health based on the ageing type (p>0.05), and the results

Catquest-9SF is a 9-item visual disability questionnaire developed for evaluating patient-reported outcome measures after cataract surgery. The aim of this study was to use Rasch analysis to determine the responsiveness of Catquest-9SF for corneal transplant patients. Patients who underwent corneal transplantation primarily to improve vision were included. One group (n = 199) completed the Catquest-9SF questionnaire before corneal transplantation and a second independent group (n = 199) completed the questionnaire 2 years after surgery. All patients were recorded in the Swedish Cornea Registry, which provided clinical and demographic data for the study. Winsteps software v.3.91.0 (Winsteps.com, Beaverton, OR) was used to assess the fit of the Catquest-9SF data to the Rasch model. Rasch analysis showed that Catquest-9SF applied to corneal transplant patients was unidimensional (infit range, 0.73-1.32; outfit range, 0.81-1.35), and therefore, measured a single underlying construct (visual disability). The Rasch model explained 68.5% of raw variance. The response categories of the 9-item questionnaire were ordered, and the category thresholds were well defined. Item difficulty matched the level of patients' ability (0.36 logit difference between the means). Precision in terms of person separation (3.09) and person reliability (0.91) was good. Differential item functioning was notable for only 1 item (satisfaction with vision), which had a differential item functioning contrast of 1.08 logit. Rasch analysis showed that Catquest-9SF is a valid instrument for measuring visual disability in patients who have undergone corneal transplantation primarily to improve vision.

Since 2013, the Robert Wood Johnson Foundation (RWJF) has embarked on a pioneering effort to advance a Culture of Health. The Culture of Health action framework is founded on a vision in which "everyone in our diverse society leads healthier lives now and for generations to come." To put the Culture of Health vision into action, RWJF asked RAND Health to support the development of an action framework and measurement strategy. This article summarizes the stakeholder engagement efforts that RAND used to inform this work. It draws on a series of interviews and focus groups that RAND researchers conducted with stakeholders both within and outside the United States. It should be of interest to RWJF, as well as to those individuals and organizations interested in advancing the Culture of Health action framework. Given that RWJF is focused on using the Culture of Health action framework and measures to catalyze national dialogue about content and investments to improve population health and well-being, the study should be beneficial to a range of national, state, and local leaders across a variety of sectors that contribute to health as described by the Culture of Health action framework.

To investigate the relationships among obesity, physical activity and quality of life (QOL) in Hong Kong Chinese adults. A cross-sectional study involving 876 subjects (32.9% men and 67.1% women, mean age: 34.8 +/- 7.9 years) from a nonmanual working population. The Medical Outcome Study Short Form 36 (SF-36, Chinese version) was used for health-related QOL. Level of physical activity was assessed with self-reported questionnaire. Obesity was defined as body mass index > or = 25 kg/m2. 31% of men and 9% of women were obese (overall 16.0%). Obese subjects had lower scores on some of the SF-36 subscales. As the level of physical activity decreased, mean scores on most SF-36 subscales also progressively decreased. Obese women who had no regular physical activity had lower scores on some QOL subscales than obese women who had some regular physical activity. Among this Hong Kong Chinese sample, both obesity and lack of physical activity are associated with lower scores on QOL.

We compared general and disease specific health related quality of life (QOL) after surgery and radiotherapy for prostate cancer. We performed a retrospective survey of patients treated between 1992 and 2001. General and disease specific health related QOL were assessed by the short form 36 health survey questionnaire (SF-36) and the University of California-Los Angels Prostate Cancer Index (UCLA PCI). We mailed questionnaires of QOL survey and obtained from 143 and 73 men who treated surgery and radiotherapy. The median ages of surgery and radiation group were 70.9 and 79.2 years old, and the median periods after treatment were 2.7 and 2.0 years, respectively. Physical function, role physical, social functioning and mental health were higher score in surgery group than radiation group, however, general health perceptions was higher in radiation group among SF-36. Surgery group had worse urinary function and better sexual function compared with radiation group. Multi-variable analysis showed that scores of social functioning, mental health and sexual function were most influenced by each modality, the scores of physical function, role physical, urinary function and sexual bother were most influenced by age, and the score of general health perceptions and body pain was most influenced by the existence of recurrence. This cross-sectional survey cleared the differences of QOL after surgery and radiotherapy, and the influences of each modality. However, because of difference in background of each group, longitudinal investigation will need to aid patients in the decision making process. (author)

Acute myocardial infarction (AMI) is a life-changing event that affects both the patient and the family and can have an influence on hope as well as HRQoL during the recovery period. To compare self-rated scores of hope and health-related quality of life (HRQoL) 1, 7, 13 and 25 months, after an AMI with regard to (i) differences across time, and (ii) differences between patients and their partners. Explorative and longitudinal study. In this nonrandomized study, Short Form 36 Health Questionnaire (SF-36) and Herth Hope Index-Swedish (HHI-S) questionnaires were completed by thirteen post-AMI patients and their partners. Data were collected on four occasions. In general, hope as well as HRQoL scores increased over time. A 2 (groups) × 4 (times) anova for mixed design showed significant changes in mental as well as in physical health over time but no significant effect of group on mental or physical health. Calculation of the minimum detectable change (MDC-index) for HHI-S and SF-36 revealed that scores between data collection points were not stable. conclusion: Our results show that although hope and HRQoL scores increased, only a few of the changes were statistically significant. Neither HHI-S nor SF-36 seems to measure stable states. Changes in hope and HRQoL levels may be due to participants striving to adapt to the current situation. These results can be used in the training of nursing staff to enhance their understanding of the significance of a family-centred approach after an AMI. © 2012 Nordic College of Caring Science.

The effects of tobacco smoke, mild/moderate COPD disease and their combined effect on health status (HS), body composition (BC), and exercise capacity (EC) impairment are still unclear. We hypothesized that smoking and early COPD have a joint negative influence on these outcomes. We evaluated 32 smokers (smoking history >10 pack/years), 32 mild/moderate COPD (current smokers or former smokers), and 32 never smokers. All individuals underwent medical and smoking status evaluations, pre and post-bronchodilator spirometry, BC [fat-free mass (FFM) and FFM index (FFMI)], EC [six-minute walk distance (6MWD)] and HS [Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36)]. FFM (p = 0.02) and FFMI (p = 0.008) were lower in COPD than never smokers. 6MWT, as a percentage of reference values for the Brazilian population, was lower in COPD and smokers than never smokers (p = 0.01). Smokers showed worse SF-36 score for functional capacity than never smokers (psmoking were inversely associated with FFMI, 6MWD and HS. Smoking and early COPD have a joint negative influence on body composition, exercise capacity and health status.

Background Anti-neutrophil cytoplasm antibody-associated vasculitis (AAV) can present with a broad spectrum of signs and symptoms. The relative effects of different manifestations on health related quality of life (HRQOL) is unknown. Methods We conducted an individual patient data meta-analysis of baseline Short Form 36 (SF-36) scores from four randomized controlled trials of patients with newly diagnosed AAV. We determined the associations between organ manifestations at trial entry and the SF-36 Physical Composite Score (PCS) and Mental Composite Score (MCS) using mixed effects models adjusted for demographic factors. Associations with each of the 8 domains of the SF-36 were further explored using multivariate multiple regression. Results SF-36 data was available from 346 patients. Older age (−0.11 points/year; 95% Confidence Interval [CI] −0.21 to −0.012; p=0.029) and neurologic involvement (−5.84, p<0.001) at baseline were associated with lower Physical Composite Scores. Physical Function scores were the most affected and older age (−0.25 points per year, 95% Confidence Interval [CI] −0.38 to −0.11; p<0.001) scores and neurologic involvement (−8.48 points, 95% CI −12.90 to −4.06; p<0.001) had the largest effects. The MCS was negatively affected only by chest involvement (p=0.027) but this effect was not exerted in any particular domain. Conclusions HRQOL in patients with newly diagnosed AAV are complex and incompletely explained by their organ system manifestations. PMID:21452254

Smoking is associated with impaired health-related quality of life (HRQL) across all populations. Because decline in lung function and risk for COPD are lower in New Mexican Hispanic smokers compared with their non-Hispanic white (NHW) counterparts, the goal of this study was to ascertain whether HRQL differs between these two racial/ethnic groups and determine the factors that contribute to this difference. We compared the score results of the Medical Outcomes Short-Form 36 Health Survey (SF-36) and St. George's Respiratory Questionnaire (SGRQ) in 378 Hispanic subjects and 1,597 NHW subjects enrolled in the Lovelace Smokers' Cohort (LSC) from New Mexico. The associations of race/ethnicity with SGRQ and SF-36 were assessed by using multivariable regression. Physical functioning (difference, -4.5; P = .0008) but not mental health or role emotional domains of the SF-36 was worse in Hispanic smokers than in their NWH counterparts in multivariable analysis. SGRQ total score and its activity and impact subscores were worse in Hispanic (vs NHW) smokers after adjustment for education level, current smoking, pack-years smoked, BMI, number of comorbidities, and FEV 1 % predicted (difference range, 2.9-5.0; all comparisons, P ≤ .001). Although the difference in the SGRQ activity domain was above the clinically important difference of four units, the total score was not. New Mexican Hispanic smokers have clinically relevant, lower HRQL than their NHW counterparts. A perception of diminished physical functioning and impairment in daily life activities contribute to the poorer HRQL among Hispanic subjects. Copyright © 2016 American College of Chest Physicians.

Obesity has a negative impact on health-related quality of life (HRQoL). The SCALE Obesity and Prediabetes study investigated the effect of liraglutide 3.0 mg, as adjunct to diet and exercise, on HRQoL in patients with obesity [body mass index (BMI) ≥ 30 kg m(-2) ] or overweight (BMI ≥ 27 kg m(-2) ) with comorbidity. Participants were advised on a 500 kcal d(-1) deficit diet and a 150-min week(-1) exercise programme and were randomised 2:1 to once-daily subcutaneous liraglutide 3.0 mg or placebo. HRQoL was assessed using the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) and Short-Form 36 (SF-36) v2 health questionnaires. Individuals on liraglutide 3.0 mg (n = 2046) had significantly greater improvements in IWQOL-Lite total score (10.6 ± 13.3) vs. placebo (n = 1020) (7.7 ± 12.8) and SF-36 physical (PCS) and mental (MCS) component summary scores (PCS, 3.6 ± 6.8; MCS, 0.2 ± 8.1) vs. placebo (PCS, 2.2 ± 7.7; MCS, -0.9 ± 9.1). The estimated treatment differences were IWQOL-Lite total score 3.1 (95% CI: 2.2; 4.0), P 3.0 mg vs. placebo. More patients on liraglutide 3.0 mg experienced meaningful improvement on the IWQOL-Lite total (P < 0.0001) and the SF-36 PCS (P < 0.0001) scores. © 2016 The Authors.

Although health-related quality of life (HRQL) has been linked to numerous factors in older adults, limited or conflicting studies have investigated variables explaining HRQL in healthy, community-dwelling older adults. The purpose of this study was to determine whether physical activity, gait speed, balance, strength, endurance, and flexibility were associated with HRQL in healthy, community-dwelling older adults. Participants of this cross-sectional, correlational research design study included residents of a senior living community, aged 60 years and older who were independent in at least unlimited household ambulation. These residents participated in tests of physical activity, gait speed, balance, strength, endurance, flexibility, and HRQL (Medical Outcomes Study Short-Form Health Survey, SF-36). The physical (PCS) and mental (MCS) component summary scores of the SF-36 were calculated. Data were collected on 84 participants (mean [SD] age = 78.6 (5.9) years, 54.8% women). Significant correlations were found between the PCS and fast gait speed (FGS) (r = 0.43; p Fullerton Advanced Balance Scale (r = 0.44; p balance, and lower body strength were associated with the PCS of the SF-36; however, FGS was the only variable that uniquely contributed to the variance in the PCS. Body mass index was associated with the MCS; however, only balance uniquely contributed to the variance in the MCS. Physical activity was not associated with the PCS or MCS. The results of this study support the assessment of FGS in community-dwelling older adults to gain insight into physical health status. Interventions directed toward FGS, balance, and BMI may contribute to optimum HRQL in this population.

 Objective. The aim of this study was to compare the health-related quality of life (HRQoL) and self-esteem of patients who underwent split-thickness skin grafting, when either cellulose dressings or rayon dressings were applied to the donor sites. A total of 25 patients, who were enrolled at five participant hospitals and required split-thickness skin grafting for various clinical reasons, were randomized into two treatment groups, the rayon dressing group (n = 13), or the cellulose dressing group (n = 12). All patients were assessed preoperatively and 60 days postoperatively. The HRQoL was assessed with the Short Form-36 (SF-36) health survey questionnaire, and self-esteem was evaluated using the Rosenberg Self-Esteem Scale (RSE)/UNIFESP-EPM (Brazilian versions). There were no surgery-related complications during the study period. In both treatment groups, SF-36 scores for emotional role, mental health, vitality, and general health decreased from baseline. RSE scores increased from baseline in both treatment groups, showing a reduction in self-esteem after treatment. There was a statistical difference (P = 0.024) in the SF-36 bodily pain domain for the rayon group. There were no significant differences in HRQoL and self-esteem between treatment groups. In the rayon-dressing group, there was a significant decrease in bodily pain from baseline .

Although Short Form (SF)-12 × 2® has been extensively studied and used as a valid measure of health-related quality of life in a variety of population groups, no systematic studies have described the reliability of the measure in patients with behavioral conditions or serious mental illness (SMI). We assessed the internal consistency, split-half reliability and annual test-retest correlations in a sample of 1587 participants with either a combination of physical and behavioral conditions or SMI. The Mosier's alpha was 0.70 for the Physical Composite Scale (PCS) and 0.69 for the Mental Health Composite Scale (MCS), indicating good internal consistency. We observed strong correlations between physical functioning, physical role and body pain scales (r = 0.55-0.56), and between social functioning, emotional role, and mental health (r = 0.53-0.58). We calculated split-half reliabilities to be 0.74 for physical functioning, 0.75 for physical role, 0.73 for emotional role and 0.65 for mental health respectively. We assessed the annual test-retest correlation using intraclass correlation (ICC) and found an ICC of 0.61 for PCS and 0.57 for MCS composite scores, adjusting for age, sex, race/ethnicity, and CRG. We found no decline in the correlations between baseline and the following study years until year 3. Our results encourage using SF-12v2® to assess health-related quality of life in the Medicaid population with combined physical and behavioral conditions or similar cohorts.

Several studies have compared instrumented PLF with other surgical approaches in terms of clinical outcomes, however little is known about the postoperative HRQoL of patients, especially as regards to degenerative spondylolisthesis. A group of 62 patients, 30 women (48,4%) and 32 men (51,6%) with mean age 56,73 (SD +/- 9,58) years old, were selected to participate in a 2-year follow-up. Their pain was assessed via the visual analogue scale (VAS) for low back pain (VASBP) and leg pain (VASLP) separately. Their HRQoL was evaluated by the Short Form (36) Health Survey (SF-36). Both scales, VAS and SF36, were measured and re-assessed at 10 days, 1 month, 3 months, 6 months, 12 months and 2 years. VASBP, VASLP and each parameter of SF36 presented statistically significant improvement (p<0.01). VASBP, VASLP and SF36 scores did not differ significantly between men and women (p≥0.05). The most notable amelioration of VASBP, VASLP was observed within the first 10 days and the maximum improvement within the first 3 months. From that point, a stabilization of the parameters was observed. The majority of SF36 parameters, and especially PF (physical functioning) and BP (bodily pain), presented statistically significant improvement within the follow up depicting a very similar improvement pattern to that of VAS. We conclude that instrumented PLF ameliorates impressively the HRQoL of patients with degenerative spondylolisthesis after 2 years of follow-up, with pain recession being the most crucial factor responsible for this improvement.

Full Text Available Abstract Background As Iran started to experience population ageing, it is important to consider and address the elderly people's needs and concerns, which might have direct impacts on their well-being and quality of life. There have been only a few researches into different aspects of life of the elderly population in Iran including their health-related quality of life. The purpose of this study was to measure health-related quality of life (HRQoL of elderly Iranians and to identify its some determinant factors. Methods This was a cross-sectional survey of a random sample of community residents of Tehran aged 65 years old and over. HRQoL was measured using the Short From Health Survey (SF-36. The study participants were interviewed at their homes. Uni-variate analysis was performed for group comparison and logistic regression analysis conducted to predict quality of life determinants. Results In all, 400 elderly Iranian were interviewed. The majority of the participants were men (56.5% and almost half of the participants were illiterate (n = 199, 49.8%. Eighty-five percent of the elderly were living with their family or relatives and about 70% were married. Only 12% of participants evaluated their economic status as being good and most of people had moderate or poor economic status. The mean scores for the SF-36 subscales ranged from 70.0 (SD = 25.9 for physical functioning to 53.5 (SD = 29.1 for bodily pain and in general, the respondents significantly showed better condition on mental component of the SF-36 than its physical component (mean scores 63.8 versus 55.0. Performing uni-variate analysis we found that women reported significantly poorer HRQoL. Multiple logistic regression analysis showed that for the physical component summary score of the SF-36, age, gender, education and economic status were significant determinants of poorer physical health-related quality of life; while for the mental component summary score only gender and

The present study examined the relationship between self-reported physical health, depressive symptoms, and the occurrence of depression diagnosis in Hispanic female dementia caregivers. Participants were 89 Hispanic female dementia caregivers. This study used a cross-sectional design. Baseline depression and physical health data were collected from participants enrolled in the 'Reducing Stress in Hispanic Anglo Dementia Caregivers' study sponsored by the National Institute on Aging. Physical health was assessed using the Medical Outcome Study Short Form-36 (SF-36), a one-item self-report health rating, body mass index, and the presence or history of self-reported physical illness. Depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale (CES-D). The occurrence of depression diagnosis was assessed using the Clinical Interview for DSM-IV Axis I Disorders (SCID). Multiple linear and logistic regression analysis was used to examine the extent to which indices of physical health and depressive symptoms accounted for variance in participants' depressive symptoms and depressive diagnoses. Self-reported indices of health (e.g., SF-36) accounted for a significant portion of variance in both CES-D scores and SCID diagnoses. Caregivers who reported worsened health tended to report increased symptoms of depression on the CES-D and increased likelihood of an SCID diagnosis of a depressive disorder. Self-reported health indices are helpful in identifying Hispanic dementia caregivers at risk for clinical levels of depression.

Full Text Available Abstract Background Measures of multimorbidity are often applied to source data, populations or outcomes outside the scope of their original developmental work. As the development of a multimorbidity measure is influenced by the population and outcome used, these influences should be taken into account when selecting a multimorbidity index. The aim of this study was to compare the strength of the association of health-related quality of life (HRQOL with three multimorbidity indices: the Cumulative Illness Rating Scale (CIRS, the Charlson index (Charlson and the Functional Comorbidity Index (FCI. The first two indices were not developed in light of HRQOL. Methods We used data on chronic diseases and on the SF-36 questionnaire assessing HRQOL of 238 adult primary care patients who participated in a previous study. We extracted all the diagnoses for every patient from chart review to score the CIRS, the FCI and the Charlson. Data for potential confounders (age, sex, self-perceived economic status and self-perceived social support were also collected. We calculated the Pearson correlation coefficients (r of the SF-36 scores with the three measures of multimorbidity, as well as the coefficient of determination, R2, while controlling for confounders. Results The r values for the CIRS (range: -0.55 to -0.18 were always higher than those for the FCI (-0.47 to -0.10 and Charlson (-0.31 to -0.04 indices. The CIRS explained the highest percent of variation in all scores of the SF-36, except for the Mental Component Summary Score where the variation was not significant. Variations explained by the FCI were significant in all scores of SF-36 measuring physical health and in two scales evaluating mental health. Variations explained by the Charlson were significant in only three scores measuring physical health. Conclusion The CIRS is a better choice as a measure of multimorbidity than the FCI and the Charlson when HRQOL is the outcome of interest. However

Prisoners constitute a group with increased health and social care needs. Although implementing policies that aim at improving outcomes within this population should be a priority area, studies that attempt to assess health outcomes and health related quality of life (HRQoL) in this population are limited. To assess HRQoL in a prison population in Greece and to explore the relationship between HRQoL and a set of individual sociodemographic and health related characteristics and characteristics of detention. A cross-sectional study involving 100 male prisoners was conducted in the prison of Corinth in Greece. HRQoL was assessed through the use of the SF-36 and the EQ-5D. The mean physical and mental summary scores of the SF-36 were 55.33 and 46.82, respectively. The EQ-VAS mean score was 76.41%, while the EQ-5D index was 0.72. Multivariate analysis identified a statistical relationship between HRQoL and the conditions of detention, controlling for the effect of sociodemographic characteristics, morbidity, and mental problems. The use of narcotics in particular is significantly associated with lower HRQoL. Implementation of policies that aim at preventing the use of narcotics within the prison environment is expected to contribute to improved HRQoL in this population.

The impact of lumbar spinal surgery is commonly evaluated with three patient-reported outcome measures: Oswestry Disability Index (ODI), the physical component summary (PCS) of the Short Form of the Medical Outcomes Study (SF-36), and pain scales. A minimum clinically important difference (MCID) is a threshold used to measure the effect of clinical treatments. Variable threshold values have been proposed as MCID for those instruments despite a lack of agreement on the optimal MCID calculation method. This study has three purposes. First, to illustrate the range of values obtained by common anchor-based and distribution-based methods to calculate MCID. Second, to determine a statistically sound and clinically meaningful MCID for ODI, PCS, back pain scale, and leg pain scale in lumbar spine surgery patients. Third, to compare the discriminative ability of two anchors: a global health assessment and a rating of satisfaction with the results of the surgery. This study is a review of prospectively collected patient-reported outcomes data. A total of 454 patients from a large database of surgeries performed by the Lumbar Spine Study Group with a 1-year follow-up on either ODI or PCS were included in the study. Preoperative and 1-year postoperative scores for ODI, PCS, back pain scale, leg pain scale, health transition item (HTI) of the SF-36, and Satisfaction with Results scales. ODI, SF-36, and pain scales were administered before and 1 year after spinal surgery. Several candidate MCID calculation methods were applied to the data and the resulting values were compared. The HTI of the SF-36 was used as the anchor and compared with a second anchor (Satisfaction with Results scale). Potential MCID calculations yielded a range of values: fivefold for ODI, PCS, and leg pain, 10-fold for back pain. Threshold values obtained with the two anchors were very similar. The minimum detectable change (MDC) appears as a statistically and clinically appropriate MCID value. MCID values

Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are life-threatening diseases with a high burden of symptoms. Although depression, anxiety, and reduced health related quality of life (HRQOL) have also been reported, a comparative analysis which explores these traits and their underlying factors was lacking. A retrospective analysis of depression, anxiety, and health related QOL was conducted using a Hospital anxiety and depression scale (HADS) as well as the SF-36 HRQOL questionnaire. Results from these tools were compared with haemodynamic and functional parameters in 70 PAH and 23 CTEPH outpatients from a German tertiary care center specializing in pulmonary hypertension. Although HRQOL was reduced in both cohorts of patients, individuals diagnosed with CTEPH scored lower in nearly all SF-36 parameters. Significance was noted in both "mental health" (p = 0.01) and "mental component summary score" (MCS) (p = 0.02). Depression was also more frequent in patients with CTEPH (56%) than in patients with PAH (30%), (p = 0.03). Overall, depression and anxiety correlated with most SF-36 scales in both PAH and CTEPH. In CTEPH, depression also correlated with the Borg Dyspnea Scale (r = 0.44, p = 0.01). These patients also had significantly lower pCO 2 levels than the PAH cohort reflecting more severe ventilation/perfusion mismatch. All other haemodynamic and functional parameters did not differ across the groups. While both cohorts of patients suffer from a reduced HRQOL as well as depression and anxiety, decreases in mental health parameters are more pronounced in the CTEPH cohort. This suggests a strong effort to improve early detection, especially in dyspneic patients with classical risk factors for CTEPH and PAH and argues for mental illness interventions alongside routine clinical care provided to patients diagnosed with PAH or CTEPH.

This study aimed to evaluate the health-related quality of life of medical students participating in a large Brazilian government loan programme for undergraduate students in private schools.A cross-sectional study in a stratified sample of students from a private medical school in Salvador, Brazil, evaluated their health-related quality of life by using a Brazilian Portuguese version of the 36-item Short Form Health Survey questionnaire (SF-36).Students supported by the loan programme consistently presented lower mean scores in all SF-36 domains and in the physical and mental component summary scores than those who were not in the programme. Students supported by the loan programme presented systematically lower physical and mental component mean scores, after stratification by age, gender, school year, physical activity, sleepiness, headache, having a car, having a housemaid, living with family, and living in a rented house.The loan programme has enabled less wealthy undergraduate students to attend private medical schools in Brazil. However, this support is insufficient to improve students' health-related quality of life during medical school, as compared with students who do not participate in the programme. Because of a poorer health-related quality of life, students supported by the loan programme deserve special attention from private medical schools.

Panic disorder (PD) is a very common anxiety disorder and is often a chronic disabling condition. However, little is known about the factors that predict health-related quality of life (HRQOL) other than sociodemographic factors and illness-related symptomatology that explain HRQOL in only small to modest degrees. This study explored whether anxiety-related individual traits including anxiety sensitivity and trait anxiety can predict independently HRQOL in panic patients. Patients with panic disorder with or without agoraphobia (N=230) who met the diagnostic criteria in the Structured Clinical Interview for DSM-IV were recruited. Stepwise regression analysis was performed to determine the factors that predict HRQOL in panic disorder. HRQOL was assessed by the 36-item Short-Form Health Survey (SF-36). Anxiety sensitivity was an independent predictor of bodily pain and social functioning whereas trait anxiety independently predicted all of the eight domains of the SF-36. Our data suggests that the assessment of symptomatology as well as individual anxiety-related trait should be included in the evaluation of HRQOL in panic patients.

Primary hyperhidrosis affects approximately 3% of the population and reduces quality of life in affected persons. Few studies have investigated the symptoms of anxiety, depression and hazardous alcohol consumption among those with hyperhidrosis and the effect of treatment with botulinum toxin. The first aim of this study was to investigate the effect of primary hyperhidrosis on mental and physical health, and alcohol consumption. Our second aim was to study whether and how treatment with botulinum toxin changed these effects. One hundred and fourteen patients answered questionnaires regarding hyperhidrosis and symptoms, including hyperhidrosis disease severity scale (HDSS), visual analog scale (VAS) 10-point scale for hyperhidrosis symptoms, hospital anxiety and depression scale (HADS), alcohol use disorder identification test (AUDIT) and short-form health survey (SF-36) before treatment with botulinum toxin and 2 weeks after. The age of onset of hyperhidrosis was on average 13.4 years and 48% described heredity for hyperhidrosis. Significant improvements were noted in patients with axillary and palmar hyperhidrosis regarding mean HDSS, VAS 10-point scale, HADS, SF-36 and sweat-related health problems 2 weeks after treatment with botulinum toxin. Changes in mean AUDIT for all participants were not significant. Primary hyperhidrosis mainly impairs mental rather than physical aspects of life and also interferes with specific daily activities of the affected individuals. Despite this, our patients did not show signs of anxiety, depression or hazardous alcohol consumption. Treatment with botulinum toxin reduced sweat-related problems and led to significant improvements in HDSS, VAS, HADS and SF-36 in our patients. © 2016 Japanese Dermatological Association.

SF 5 CF 3 and SF 6 are the most effective greenhouse gases on a per molecule basis in the atmosphere. Original laboratory trial for photoreduction of them by use of propene as a reactant was performed to develop a novel technique to destroy them. The highly reductive radicals produced during the photolysis of propene at 184.9 nm, such as ·CH 3 , ·C 2 H 3 , and ·C 3 H 5 , could efficiently decompose SF 6 and SF 5 CF 3 to CH 4 , elemental sulfur and trace amounts of fluorinated organic compounds. It was further demonstrated that the destruction and removal efficiency (DRE) of SF 5 X (X represented F or CF 3 ) was highly dependent on the initial propene-to-SF 5 X ratio. The addition of certain amounts of oxygen and water vapor not only enhanced the DRE but avoided the generation of deposits. In both systems, employment nitrogen as dilution gas lessened the DRE slightly. Given the advantage of less toxic products, the technique might contribute to SF 5 X remediation

Obesity has a negative impact on health-related quality of life (HRQoL). The SCALE Obesity and Prediabetes study investigated the effect of liraglutide 3.0 mg, as adjunct to diet and exercise, on HRQoL in patients with obesity [body mass index (BMI) ≥ 30 kg m−2] or overweight (BMI ≥ 27 kg m−2......) with comorbidity. Participants were advised on a 500 kcal d−1 deficit diet and a 150-min week−1 exercise programme and were randomised 2:1 to once-daily subcutaneous liraglutide 3.0 mg or placebo. HRQoL was assessed using the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) and Short-Form 36 (SF-36) v2 health...... questionnaires. Individuals on liraglutide 3.0 mg (n = 2046) had significantly greater improvements in IWQOL-Lite total score (10.6 ± 13.3) vs. placebo (n = 1020) (7.7 ± 12.8) and SF-36 physical (PCS) and mental (MCS) component summary scores (PCS, 3.6 ± 6.8; MCS, 0.2 ± 8.1) vs. placebo (PCS, 2.2 ± 7.7; MCS, −0...

Tapering of anti-tumour necrosis factor (TNF) therapy appears feasible, safe and effective in selected patients with rheumatoid arthritis (RA). Depression is highly prevalent in RA and may impact on flare incidence through various mechanisms. This study aims to investigate if psychological states predict flare in patients' dose tapering their anti-TNF therapy. This study is a post-hoc analysis of the Optimizing TNF Tapering in RA trial, a multicentre, randomised, open-label study investigating anti-TNF tapering in RA patients with sustained low disease activity. Patient-reported outcomes (Health Assessment Questionnaire, EuroQol 5-dimension scale, Functional Assessment of Chronic Illness Therapy fatigue scale (FACIT-F), 36-Item Short Form Survey (SF-36)) were collected at baseline. The primary outcome was flare, defined as an increase in 28-joint count Disease Activity Score (DAS28) ≥0.6 and ≥1 swollen joint. Discrete-time survival models were used to identify patient-reported outcomes that predict flare. Ninety-seven patients were randomised to taper their anti-TNF dose by either 33% or 66%. Forty-one patients flared. Higher baseline DAS28 score was associated with flare (adjusted HR 1.96 (95% CI 1.18 to 3.24), p=0.01). Disability (SF-36 physical component score), fatigue (FACIT-F) and mental health (SF-36 mental health subscale (MH)) predicted flare in unadjusted models. In multivariate analyses, only SF-36 MH remained a statistically significant predictor of flare (adjusted HR per 10 units 0.74 (95% CI 0.60 to 0.93), p=0.01). Baseline DAS28 and mental health status are independently associated with flare in patients who taper their anti-TNF therapy. Fatigue and function also associate with flare but the effect disappears when adjusting for confounders. Given these findings, mental health and functional status should be considered in anti-TNF tapering decisions in order to optimise the likelihood of success.

Systematic literature review. To examine the available literature on health related quality of life (HRQOL) assessment in metastatic disease of the spine and identify the optimal functional outcome scales to be used in developing a disease-specific tool. There is a lack of consensus in the use of HRQOL measures in patients with metastatic spine disease. A systematic review was conducted using MEDLINE, EMBASE, the Science Citation Index (ISI), the Cumulative Index to Nursing and Allied Health Literature, the PsycINFO, the Allied and Complementary Medicine (AMED), Cochrane Reviews and Global Health databases for clinical studies addressing metastatic spine disease from 1966 through 2008. The validity of outcome tools was established by linkage analysis with the International Classification of Functioning Disability and Health (ICF). One hundred forty-one clinical studies met inclusion criteria including 10,347 patients. Only 5 moderate grade and 1 high grade study were identified. Thirty- four studies used a patient self-assessment instrument to assess health status. None of the instruments were validated for metastatic spine patients. The most commonly used Pi-by-no tools were SF-36, SIP 5, and the ADL. None of the studies defined health related quality of life (HRQOL) or justified the choice of instrument. The most commonly used cancer-specific tools were ECOG, EORTC QCQ-C30, and EUROQOL 5D. Based on frequency of citation and on correlation with the International Classification of Functioning Disability and Health, the ECOG and SF36 were judged as most valid and reliable. A systematic review of the available evidence suggests that valid and reliable health related quality of life measures exist for the assessment of oncology patients; however, a disease-specific tool for metastatic spine disease awaits development. Until such time as a disease-specific tool is available, we recommend that the ECOG and SF-36 be considered for use in studies addressing the outcome

United States military personnel reported various symptoms after deployment to the Persian Gulf during the 1991 Gulf War. However, the symptoms' long-term prevalence and association with deployment remain controversial. To assess and compare the prevalence of selected medical conditions in a national cohort of deployed and nondeployed Gulf War veterans who were evaluated by direct medical and teledermatologic examinations. A cross-sectional prevalence study performed 10 years after the 1991 Gulf War. Veterans were examined at 1 of 16 Veterans Affairs medical centers. Deployed (n = 1061) and nondeployed (n = 1128) veterans of the 1991 Gulf War. Primary outcome measures included fibromyalgia, the chronic fatigue syndrome, dermatologic conditions, dyspepsia, physical health-related quality of life (Short Form-36 [SF-36]), hypertension, obstructive lung disease, arthralgias, and peripheral neuropathy. Of 12 conditions, only 4 conditions were more prevalent among deployed than nondeployed veterans: fibromyalgia (deployed, 2.0%; nondeployed, 1.2%; odds ratio, 2.32 [95% CI, 1.02 to 5.27]); the chronic fatigue syndrome (deployed, 1.6%; nondeployed 0.1%; odds ratio, 40.6 [CI, 10.2 to 161]); dermatologic conditions (deployed, 34.6%; nondeployed, 26.8%; odds ratio, 1.38 [CI, 1.06 to 1.80]), and dyspepsia (deployed, 9.1%; nondeployed, 6.0%; odds ratio, 1.87 [CI, 1.16 to 2.99]). The mean physical component summary score of the SF-36 for deployed and nondeployed veterans was 49.3 and 50.8, respectively. Relatively low participation rates introduce potential participation bias, and deployment-related illnesses that resolved before the research examination could not, by design, be detected. Ten years after the Gulf War, the physical health of deployed and nondeployed veterans is similar. However, Gulf War deployment is associated with an increased risk for fibromyalgia, the chronic fatigue syndrome, skin conditions, dyspepsia, and a clinically insignificant decrease in the SF-36

The aim of this study was to evaluate the associations between chronic inflammatory skin conditions and patients' emotional state and quality of life. The following self-rated questionnaires were used: Emotional State Questionnaire, a self-report scale assessing depression and anxiety symptoms; Dermatology Life Quality Index (DLQI); and RAND-36, a measure of health-related quality of life. The study group comprised 40 patients with psoriasis, 40 with eczema, 40 with acne, 15 with seborrhoeic dermatitis and 40 healthy controls. Patients with chronic skin diseases had lower DLQI and lower RAND-36 physical functioning scores, more perceived physical limitations and pain, and lower emotional well-being and general health ratings compared with the control group. In conclusion, chronic skin diseases are associated with symptoms of emotional distress, in particular insomnia and general anxiety.

Concerns over falls and falls risk are precursors to walker use. We compared the SF-36 scores of 26 women and 14 men, mean age 86.8 ± 6.0 years based on walker use and faller status. An analysis of covariance (ANCOVA with age as the covariate, compared groups for the SF-36 constructs and totals score. Significant differences were noted between walker users and nonusers in physical functioning, role limitations due to physical problems, general health, and the total SF-36 score. Pairwise comparisons favored nonusers, while no differences were seen due to faller status. Walker use is associated with lower self-perceptions of physical functioning, role limitations due to physical problems, and general health in assisted-living residents. Faller status is not associated with self-perceived health status. Although walker use aids mobility and lowers the probability of falls, further research is needed to determine if the prescription of assistive devices has a more negative impact on self-perceived health than does falling. This possibility could be explained, in part, by the greater activity levels of those individuals who do not depend on walkers.Keywords: physical function, threshold, walking aid, elderly, perceived health

Broad horizons SETI, SF and education

Science.gov (United States)

Griffiths, Martin

2004-04-01

Science fiction (SF) is often perceived as a ‘fringe’ form of entertainment that excites the socially challenged. This misperception detracts from the critical, scientific and interpretive nature of the genre which can be directed into science teaching at school and university levels as an innovative way of exploring the cultural background, politics, leitmotif and themes of society, science and their operation. One example is the ‘alien’ theme in SF; it is perceptually one of the driving factors in the search for extraterrestrial intelligence (SETI). Such a topic can become an introduction to current technology, the motives and politics of science and the sociological implications inherent in a confrontation with the ideal of man's uniqueness in the cosmos. When applied to the SETI, SF engenders a constructive convergence in studies such as biological determinism, the evolution of life, communication, interstellar travel and methods of contact, thus enriching the consideration of possible life in the cosmos. Adopting elements of SF in lifelong learning therefore enables informed, imaginative reflection and debate that educates, trains and instructs, broadening the potential of students and their future roles by invoking an analysis of vital public, scientific and humanistic fields.

Few studies have addressed health-related quality of life (QoL) in patients who chose conservative management over dialysis. This systematic review aims to better define the role of conservative management in improving health-related QoL in patients with end-stage renal disease (ESRD). Medline, Cochrane and EMBASE were searched for prospective or retrospective studies published until June 30, 2016, that examined QoL of ESRD patients. The primary outcome was health-related QoL. Four studies were included (405 patients received dialysis and 332 received conservative management). Two studies that used the Short Form-36 Survey (SF-36) showed that the dialysis group had higher physical component scores, but the conservative management group had similar, or better, mental component scores at the end of intervention. Another study using the SF-36 showed that the physical and mental component scores of the dialysis group did not significantly change after intervention. In the conservative management group, the physical component scores did not change, but the mental component scores increased significantly over time (0.12 ± 0.32, p management group. Although there are only a limited number of published articles, ESRD patients who receive conservative management may have improved mental health-related QoL when compared with those who receive dialysis.

Inventory has been a major concern in supply chain and numerous researches have been done lately on inventory control which brought forth a number of methods that efficiently manage inventory and related overheads by reducing cost of replenishment. This research is aimed towards providing a better replenishment policy in case of multi-product, single supplier situations for chemical raw materials of textile industries in Bangladesh. It is assumed that industries currently pursue individual replenishment system. The purpose is to find out the optimum ideal cycle time and individual replenishment cycle time of each product for replenishment that will cause lowest annual holding and ordering cost, and also find the optimum ordering quantity. In this paper indirect grouping strategy has been used. It is suggested that indirect grouping Strategy outperforms direct grouping strategy when major cost is high. An algorithm by Kaspi and Rosenblatt (1991) called RAND is exercised for its simplicity and ease of application. RAND provides an ideal cycle time (T) for replenishment and integer multiplier (ki) for individual items. Thus the replenishment cycle time for each product is found as T×ki. Firstly, based on data, a comparison between currently prevailing (individual) process and RAND is provided that uses the actual demands which presents 49% improvement in total cost of replenishment. Secondly, discrepancies in demand is corrected by using Holt's method. However, demands can only be forecasted one or two months into the future because of the demand pattern of the industry under consideration. Evidently, application of RAND with corrected demand display even greater improvement. The results of this study demonstrates that cost of replenishment can be significantly reduced by applying RAND algorithm and exponential smoothing models.

The present study was to identify the quality of life (QOL), the needs of help and the mode of coping among the health personnel of Naradhiwasrajana garindra Hospital in a terrorism situation, the first research in Thailand. The chaos of separatist insurgency in the southern part of Thailand has been re-emerged since 2004. The present study was seeking for ways the health personnel coped with the situation while their quality of life and needs that were affected how they had handled the events were explored. General questionnaire, quality of life rand 36 SF-36 questionnaires, help seeking questionnaire and Mode of coping with the terrorism questionnaire were sent to all health personnel in the hospital in November 2007. 392 (65.3%) complete questionnaire were received from 600 distributed papers. They were female 328 (83.7%) and male 64 (16.3%), at the age of 21-59 years old (the mean age of 39.05 SD +/- 9.82), with three different religions, Buddhist 269 (68.6%), Muslim 122 (31.1%) and Christian 1 (0.30%). Thirty nine responses (9.9%) had been directly exposed to a terrorist attack, while 353 responses (90.1%) had a family member or friends who had been exposed. The results revealed that the overall mean scores of QOL were 73.1 +/- SD 15.5. Mean scores of male were significantly lower than female in general health, social functioning and role-emotional subscales. QOL mean scores of those with no terrorism exposure were significantly higher than those with terrorism exposure in role-physical, social functioning and mental health subscales. The most need of help for the personnel was safety of life and belongings (30.6%) followed by the need of money (23.0%). To cope with the terrorist attack, people (81.7%) would always resort to religious beliefs (72.0%) talk it out with coworkers, friends about their feelings, and (68.7%) inquire about the safety of their families and friends after the incident. Certainly, terrorism affected QOL and the most need of people in

Health-related quality of life (HRQL) data are becoming an important supplement to information pertaining to treatment outcome for cancer patients. The purpose of this study was to evaluate the HRQL outcome for oral cancer survivors after surgery plus postoperative radiotherapy (RT) and to investigate the variables associated with their HRQL. Sixty-six oral cancer patients with cancer-free survival after surgery plus postoperative RT of >2 years were enrolled. The Short Form-36 (SF-36) questionnaire in the Taiwan Chinese version was self-reported by all participants at the clinics. The linear regression model was used to analyze the socio-demographic and medical-related variables correlated with the physical component summary (PCS) and mental component summary (MCS) in SF-36. The mean scores of the eight functional domains in the SF-36 were markedly lower for oral cancer survivors compared with the Taiwanese and US norms. Those with older age, lower annual family income, more advanced cancer stage and flap reconstruction had significantly worse PCS, and those with lower annual family income, unemployment and more advanced cancer stage reported significantly worse MCS. This model accounts for 63% of variance in PCS, and 51% in MCS. These results provided patient-reported evidence that oral cancer survivors lived with a worse HRQL compared with the general Taiwanese population. Socio-economic factors and cancer stage were important factors correlated with their HRQL. (authors)

Full Text Available BACKGROUND: Occupational exposure to welding fumes is a serious occupational health problem all over the world. Welders are exposed to many occupational hazards; these hazards might cause some occupational diseases. The aim of the study was to assess the health related quality of life (HRQL of electric welders in Shanghai China and explore influencing factors to HRQL of welders. METHODS: 301 male welders (without pneumoconiosis and 305 non-dust male workers in Shanghai were enrolled in this study. Short Form-36 (SF-36 health survey questionnaires were applied in this cross-sectional study. Socio-demographic, working and health factors were also collected. Multiple stepwise regress analysis was used to identify significant factors related to the eight dimension scores. RESULTS: Six dimensions including role-physical (RP, bodily pain (BP, general health (GH, validity (VT, social function (SF, and mental health (MH were significantly worse in welders compared to non-dust workers. Multiple stepwise regress analysis results show that native place, monthly income, quantity of children, drinking, sleep time, welding type, use of personal protective equipment (PPE, great events in life, and some symptoms including dizziness, discomfort of cervical vertebra, low back pain, cough and insomnia may be influencing factors for HRQL of welders. Among these factors, only sleep time and the use of PPE were salutary. CONCLUSIONS: Some dimensions of HRQL of these welders have been affected. Enterprises which employ welders should take measures to protect the health of these people and improve their HRQL.

The instruments used were the SF-36 for patients and the SF-12 and GHQ-12 for caregivers. Classification and regression tree analysis was used to analyze the explanatory factors of HRQoL.Results: A total of 705 patients (mean age 40.4 years, median Expanded Disability Status Scale 2.5, 77.8% with relapsing-remitting MS and 551 caregivers (mean age 45.4 years participated in the study. MS patients had significantly lower HRQoL than in the general population (physical SF-36: 39.9; 95% confidence interval [CI]: 39.1–40.6; mental SF-36: 44.4; 95% CI: 43.5–45.3. Caregivers also presented lower HRQoL than general population, especially in its mental domain (mental SF-12: 46.4; 95% CI: 45.5–47.3. Moreover, according to GHQ-12, 27% of caregivers presented probable psychological distress. Disability and co-morbidity in patients, and co-morbidity and employment status in caregivers, were the most important explanatory factors of their HRQoL.Conclusions: Not only the HRQoL of patients with MS, but also that of their caregivers, is indeed notably affected. Caregivers’ HRQoL is close to population of chronic illness even that the patients sample has a mild clinical severity and that caregiving role is a usual task in the study context.Keywords: health-related quality of life, multiple sclerosis

Probabilistic mapping of descriptive health status responses onto health state utilities using Bayesian networks: an empirical analysis converting SF-12 into EQ-5D utility index in a national US sample.

As quality-adjusted life years have become the standard metric in health economic evaluations, mapping health-profile or disease-specific measures onto preference-based measures to obtain quality-adjusted life years has become a solution when health utilities are not directly available. However, current mapping methods are limited due to their predictive validity, reliability, and/or other methodological issues. We employ probability theory together with a graphical model, called a Bayesian network, to convert health-profile measures into preference-based measures and to compare the results to those estimated with current mapping methods. A sample of 19,678 adults who completed both the 12-item Short Form Health Survey (SF-12v2) and EuroQoL 5D (EQ-5D) questionnaires from the 2003 Medical Expenditure Panel Survey was split into training and validation sets. Bayesian networks were constructed to explore the probabilistic relationships between each EQ-5D domain and 12 items of the SF-12v2. The EQ-5D utility scores were estimated on the basis of the predicted probability of each response level of the 5 EQ-5D domains obtained from the Bayesian inference process using the following methods: Monte Carlo simulation, expected utility, and most-likely probability. Results were then compared with current mapping methods including multinomial logistic regression, ordinary least squares, and censored least absolute deviations. The Bayesian networks consistently outperformed other mapping models in the overall sample (mean absolute error=0.077, mean square error=0.013, and R overall=0.802), in different age groups, number of chronic conditions, and ranges of the EQ-5D index. Bayesian networks provide a new robust and natural approach to map health status responses into health utility measures for health economic evaluations.

The sf32 unique gene of Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV is a non-essential gene that could be involved in nucleocapsid organization in occlusion-derived virions.

Full Text Available A recombinant virus lacking the sf32 gene (Sf32null, unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV, was generated by homologous recombination from a bacmid comprising the complete viral genome (Sfbac. Transcriptional analysis revealed that sf32 is an early gene. Occlusion bodies (OBs of Sf32null contained 62% more genomic DNA than viruses containing the sf32 gene, Sfbac and Sf32null-repair, although Sf32null DNA was three-fold less infective when injected in vivo. Sf32null OBs were 18% larger in diameter and contained 17% more nucleocapsids within ODVs than those of Sfbac. No significant differences were detected in OB pathogenicity (50% lethal concentration, speed-of-kill or budded virus production in vivo. In contrast, the production of OBs/larva was reduced by 39% in insects infected by Sf32null compared to those infected by Sfbac. The SF32 predicted protein sequence showed homology (25% identity, 44% similarity to two adhesion proteins from Streptococcus pyogenes and a single N-mirystoylation site was predicted. We conclude that SF32 is a non-essential protein that could be involved in nucleocapsid organization during ODV assembly and occlusion, resulting in increased numbers of nucleocapsids within ODVs.

Atopic dermatitis (AD) is a chronic relapsing condition that can have considerable effects on the patients' quality of life (QOL). The aim of this study was to measure the health-related QOL in patients with AD, using generic and specific instruments, to compare the scores obtained by different instruments and to verify the relationship between them. We conducted a cross-sectional study of 132 outpatients with AD. To assess the QOL, Short Form 36 (SF-36), Dermatology Life Quality Index (DLQI) and Children's Dermatology Life Quality Index (CDLQI) were administered. In order to assess the disease severity of AD, we used the Eczema Area and Severity Index (EASI) and physician assessment of disease severity. Stressful life events during the last 12 months were assessed with Paykel's Interview for Recent Life Events. Patients with AD had inferior social functioning and mental health scores compared with the general population. The correlations between the DLQI and SF-36 were found for the mental components of the QOL. Increasing disease severity was associated with greater impairment in QOL in both, children and adults. Our study found the influence of the stressful life events on the role emotional of AD patients. These results demonstrate that AD influences health-related QOL, especially in children. This study supports the decision to use both generic and skin-specific instruments to assess the impact of AD on QOL. © 2011 Japanese Dermatological Association.
