Long-term functional outcomes in polytrauma: a fundamentally new approach is needed in prediction

PURPOSE

Modern trauma care has reduced mortality but poor long-term outcomes with low follow-up rates are common with limited recommendations for improvements. The aim of this study was to describe the impact of severe injury on the health-related quality of life, specifically characterise the non-responder population and to identify modifiable predictors of poorer outcomes.

METHODS

Five-year (2012-2016) prospective cohort study was performed at a level 1 trauma centre. Baseline Short-Form Health Survey (SF36) was collected at admission, and at 6 and 12 months postinjury together with demographics, injury mechanism and severity, psychosocial wellbeing, and return to work capacity.

RESULTS

Of the 306 consecutive patients [age 52 ± 17 years, male 72%, ISS 21 (17, 29), mortality 5%], 195 (64%) completed questionnaires at baseline, and at 12 months. Preinjury physical health scores were above the general population (53.1 vs. 50.3, p < 0.001) and mental health component was consistent with the population norms (51.7 vs. 52.9, p = 0.065). One year following injury, both physical health (13.2, 95% CI 14.8, 11.6) and mental health scores (6.0, 95% CI 8.1, 3.8) were significantly below age- and sex-adjusted preinjury baselines. Non-responders had similar ISS but with a lower admission GCS, and were more likely to be younger, and without comorbidities, employment, or university education.

CONCLUSION

Contrary to their better than population norm preinjury health status, polytrauma patients remain functionally impaired at least 1 year after injury. The identified high risk for non-responding group needs more focused efforts for follow-up. A fundamentally different approach is required in polytrauma research which identify modifiable predictors of poor long-term outcomes.

Pain Scales: What Are They and What Do They Mean

PURPOSE OF REVIEW

It is essential to have validated and reliable pain measurement tools that cover a wide range of areas and are tailored to individual patients to ensure effective pain management. The main objective of this review is to provide comprehensive information on commonly used pain scales and questionnaires, including their usefulness, intended purpose, applicability to different patient populations, and associated advantages and disadvantages.

RECENT FINDINGS

Acute pain questionnaires typically focus on measuring the severity of pain and the extent of relief achieved through interventions. Chronic pain questionnaires evaluate additional aspects such as pain-related functional limitations, psychological distress, and psychological well-being. The selection of an appropriate pain scale depends on the specific assessment objectives. Additionally, each pain scale has its strengths and limitations. Understanding the differences among these pain scales is essential for selecting the most appropriate tool tailored to individual patient needs in different settings.

CONCLUSION

Medical professionals encounter challenges in accurately assessing pain. Physicians must be familiar with the different pain scales and their applicability to specific patient population.

Prevalence of fibromyalgia among university students and its impact on their health-related quality of life: a survey-based study from Egypt

BACKGROUND

University students are more likely to experience stress, anxiety, and depression. All these factors are regarded as psychological contributors to fibromyalgia syndrome (FMS).

AIM

To investigate the prevalence and determinants of FMS among university students and its impact on their health-related quality of life (HRQoL).

METHODS

This online survey-based study involved 2146 university students who were recruited from various faculties at several Egyptian universities. The participants' demographics, medical history, academic pursuits, and sleep data were collected. To identify the existence of FMS, the 2016 updates to the 2010/2011 FMS diagnostic criteria were used. Additionally, the participants completed the Short-Form Health Survey-36 (SF-36).

RESULTS

The mean age was 21.26 ± 2.015 years and 76% were females. Of 2146 students, 266 (12.4%) fulfilled the criteria of FMS. FMS group had a significantly lower age (p < 0.001) with predominant female gender (89.5% vs. 74.1%, p < 0.001), positive family history of FMS (8.6% vs. 3.7%, p < 0.001), previous history of traffic accident (10.2% vs. 6.8%, p = 0.045), lower level of physical activity (p = 0.002),higher time spent in study per week (p = 0.002), lower sleep time (p = 0.002), with frequent walk up (p < 0.001) and snoring (p < 0.001) during sleep. Regarding HRQoL, students with FMS had significantly lower scores than students without in all domains.

CONCLUSION

FMS is prevalent among Egyptian university students and is linked to female gender, positive family history, lower levels of physical activity, and more time spent studying each week. FMS has a negative impact on HRQoL. Therefore, early detection and treatment are recommended.

Quality-of-life scores improve after 96 weeks of PEG-IFNa-2a treatment of hepatitis D: An analysis of the HIDIT-II trial

BACKGROUND & AIMS

Infection with the hepatitis D virus (HDV) causes the most severe form of viral hepatitis with a high risk to develop clinical complications of liver disease. In addition, hepatitis delta has been shown to be associated with worse patient-reported outcomes. Until recently, only pegylated interferon alfa could be used to treat hepatitis delta.

METHODS

Here, we investigated quality of life (QOL) as assessed by the Short Form 36 Health Survey (SF-36) in patients undergoing antiviral therapy with pegylated interferon alfa (PEG-IFNa-2a)-based treatment in the HIDIT-II trial. HIDIT-II was a randomized prospective trial exploring PEG-IFNa-2a with tenofovir disoproxil (TDF) or placebo for 96 weeks in patients with compensated hepatitis delta. Surveys completed by 83 study participants before, during, and after treatments were available.

RESULTS

Overall, we observed a reduced QOL of HDV patients compared with a reference population, both in physical as well as mental scores. Interestingly, PEG-IFNa-2a treatment showed only minor impairment of the QOL during therapy. Moreover, HDV-RNA clearance was not associated with relevant changes in physical or social SF-36 scores, whereas an improvement of fibrosis during treatment was associated with increased QOL. Overall, slight improvements of the QOL scores were observed 24 weeks after the end of treatment as compared with baseline. TDF co-treatment had no influence on QOL.

CONCLUSIONS

Overall, our findings suggest that PEG-IFNa-2a was reasonably tolerated even over a period of 96 weeks by hepatitis D patients reporting SF-36 questionnaires. Of note, several patients may benefit from PEG-IFNa-2a-based therapies with off-treatment improvements in quality of life.

Effects of Playing Exergames on Quality of Life among Young Adults: A 12-Week Randomized Controlled Trial

Objective: The purpose of this paper is to investigate whether playing exergames can enhance quality of life among young adults and it examines the potential moderators. Methods: A 12-week randomized controlled trial was conducted. Quality of life was measured using the short-form 36-item version (SF-36) scale. All the participants were between 20 and 24 years old in Taiwan. Participants in the intervention group (n = 55) were asked to play exergames for 12 weeks, three times a week and 30 minutes at a time, while participants in the control group (n = 62) did not play exergames. The changes in the scores on quality of life between the beginning and the end of the 12-week trial were calculated. Independent t-tests were used to analyze the differences. Results: The intervention group participants experienced an enhanced quality of life in terms of physical functioning, role-physical (role limitations due to physical health), general health, and social functioning. Moreover, the intervention group participants who were not enthusiastic about exercisers experienced an enhanced quality of life in physical functioning, role-physical, and general health. The intervention group participants who attempted to control their weight experienced enhanced general health, vitality, and mental health. Conclusion: Playing exergaming could contribute to users' quality of life in terms of both physical and mental health.

The Suitability of Measuring Patient-Reported Outcomes in Older Adults Following a Hip Fracture Using the Short-Form 36 Questionnaire: A Qualitative Description Approach

Hip-fractures (HF) in older adults are associated with poor outcomes and high costs. Measuring quality-of-care of HF patients has focused on clinical definitions rather than on measuring outcomes that are meaningful to the patient. Healthcare systems worldwide are increasingly interested in patient-reported outcome measures (PROs). The Short-form (SF36) questionnaire is a recommended measure among older adults however it's comprehensiveness and uniqueness for specific patients after a HF is not clear. The aims of this study were to: understand the perspective of the older adults experience following HF, to assess the suitability of the SF36 as a PRO for HF and to determine the best timing for questioning. A qualitative description approach was used. This took place in 2 large academic medical-centers in Israel. The inquiry was done in 2 parts by semi-structured interview. A total 15 HF patients were interviewed. Categories and themes emerging from their responses were similar to the 8 domains of the SF36 questionnaire, but the participants added clarity regarding their own needs for setting goals. In the second part, participants agreed that the SF36 reflected common issues and served as an adequate measure for personal-goal setting. The study encourages patient-centered care in older adults recovering from HF, providing evidence that the SF36 is a suitable tool for measuring PROs in HF patients. Healthcare systems focus on clinical-outcome indicators and do not reflect how the patient views his outcomes. This study provides evidence that care should be customized for each person.

Determinants of health-related quality of life across the spectrum of connective tissue diseases using latent profile analysis: Results from the LEAP cohort

OBJECTIVES

Poor health-related quality of life (HR-QoL) is well recognised in patients with connective tissue diseases (CTD). We hypothesised that subgroups of patients across the spectrum of CTD experience different HR-QoL patterns, and aimed to determine patient-level characteristics associated with these different subgroups.

METHODS

Using the eight continuous domains of the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire we performed data-driven clustering to derive latent profiles (LP) of patients with distinct HR-QoL patterns. Multivariable ordinal logistic regression was used to determine patient-level characteristics associated with each HR-QoL subgroup identified.

RESULTS

309 CTD patients completed the SF-36 questionnaire. The most impaired SF-36 domains in each disease group were vitality, general health and bodily pain. The physical component of the SF-36 was consistently more impaired compared with the mental component, with similar scores across disease groups.Three latent profiles were identified with poor (n = 89; 29%), average (n = 190; 61.4%) and excellent (n = 30; 9.7%) HR-QoL. LP were not associated with diagnostic grouping or autoantibody profiles. Black background (OR 0.22 [95% CI 0.08-0.63]), Indo-Asian background (0.39 [0.19-0.78]), concomitant fibromyalgia (0.40 [0.20-0.78]), sicca symptoms (0.56 [0.32-0.98]) and multi-morbidity (Charlson Comorbidity Index, 0.81 [0.67-0.97]) were associated with the 'poor' HR-QoL LP.

CONCLUSION

Distinct HR-QoL subgroups exist that are not primarily driven by the specific diagnosis or autoantibody profiles. We identified a number of key demographic and clinical factors associated with poor HR-QoL. These factors need to be addressed across the whole CTD spectrum as part of a holistic management approach aimed at improving overall patient outcomes.

Subjective sleep disorders and daytime sleepiness in patients with restrictive type anorexia nervosa and effects on quality of life: a case-control study

To evaluate sleep disorders and daytime drowsiness in a cohort of patients affected by anorexia nervosa and their impact on health-related quality of life. We evaluated patients affected by restricting-type of anorexia nervosa (AN-R) and healthy controls by the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, Beck Depression Index. We also used the Short-Form Health Survey (SF-36) questionnaire to assess the quality of life in both AN-R and controls. Twenty-eight out of 34 AN-R patients (82.3%) in contrast with ten out of 34 healthy subjects (29.4%) had a pathological PSQI score compared to HC (p < 0.0001). The overall PSQI score (p < 0.001), sleep quality (p < 0.001), sleep duration (p = 0.02), sleep efficiency (p = 0.002), sleep disturbances (p = 0.03) and daytime dysfunction (p = 0.004) were significantly higher in AN-R than in controls. SF36 showed significantly reduced scores of standardized physical components (p = 0.01) and standardized mental components (p < 0.001), physical function (p < 0.001), physical role (p < 0.001) and general health (p < 0.001), vitality (p < 0.001), social functioning (p  < 0.001) emotional role (p = 0.001) and mental health (p < 0.001) in AN-R. We found a significant correlation between the PSQI score and both the physical role (r = - 0.35, p = 0.03) and level of education (r = 0.38, p = 0.02). Our data showed reduced overall sleep quality without excessive daytime sleepiness in AN-R. Sleep quality correlated significantly with quality of life (physical role) and level of education.

Quality of life and patient satisfaction with outpatient care after heart transplantation in adult and pediatric patients - room for improvement?

Reduced adherence after heart transplantation increases the risk for acute rejection. Therefore, the aim of this study was to evaluate the patient's satisfaction with outpatient care and quality of life (QOL) after pediatric and adult heart transplantation. Observational study after pediatric (n = 22) and adult (n = 65) heart transplantation and the parents of the pediatric patients (n = 22) to evaluate the patients' satisfaction with outpatient care and QOL. Established standardized questionnaires were used for patient satisfaction (ZAP survey) and QOL (SF36); the latter was compared with the cohort of the BGS98 survey (BGS98 cohort). ZAP score: excellent results with almost all values >80. QOL: pediatric cohort showed significantly higher values in physical functioning (P = 0.041) and role physical (P = 0.003) but significantly lower values in the sub-scale general health (P = 0.02) compared to adult cohort. In comparison with BGS98 cohort, children showed almost similar results, whereas adult cohort showed worse values in physical and emotional functioning, but higher values regarding general health. The QOL of patients after pediatric heart transplantation is comparable to a standardized reference population in Germany, whereas adult patients show reduced physical and emotional functioning, but better values regarding general health. The patients' satisfaction with the outpatient care is very high.

Comparing the reliability and validity of the SF-36 and SF-12 in measuring quality of life among adolescents in China: a large sample cross-sectional study

OBJECTIVE

We compare the reliability and validity of the Short Form 36 (version 1, SF-36) and the Short Form 12 (version 1, SF-12) in adolescence, the period of life when a child develops into an adult, i.e., the period from puberty to maturity terminating legally at the age of majority (10-19 years), thus supplying evidence for the selection of instruments measuring the quality of life (QOL) and decision-making processes of adolescents in China.

METHODS

Stratified cluster random sampling was adopted according to geographical location, and the SF-36 was administered to assess QOL. The Pearson correlation coefficient was used to show correlation. Cronbach's alpha and construct reliability (CR) were used to evaluate the reliability of SF-36 and SF-12, while criterion validity and average variance extracted (AVE, convergence validity) were used to evaluate validity. Confirmatory factor analysis was used to calculate the load factors for the items of the SF-36 and SF-12, then to obtain the CR and AVE. The Semejima grade response model (logistic two-parameter module) in item response theory was used to estimate item discrimination, item difficulty, and item average information for the items of the SF-36 and SF-12.

RESULTS

19,428 samples were included in the study. The mean age of respondents was 14.78 years (SD = 1.77). Reliability of each domain of the SF-36 was better than for the corresponding domain of the SF-12. The domains of PF, RP, BP, and GH in SF-36 had good construct reliability (CR > 0.6). The criterion validities of some domains of the SF-36 were a little higher in some corresponding dimensions of the SF-12, except for PCS. The convergence validities of the SF-12 were higher than the SF-36 in PF, RP, BP, and PCS. The items of BP, SF, RP, and VT in the SF-12 had acceptable discrimination of items that were higher than in the SF-36. The items' average amounts of information on BP, VT, SF, RE, and MH in the SF-36 and SF-12 were poor.

CONCLUSION

Two component (PCS and MCS) measurements of the SF-12 appeared to perform at least as well as the SF-36 in cross-sectional settings in adolescence, but the reliability and validity of the 8 domains of the SF-36 were better than those of the SF-12. Some domains, for instance SF and BP, were not suitable for adolescents or need to be studied further.

Quality of life in people with transsexuality after surgery: a systematic review and meta-analysis

BACKGROUND

Several reports have demonstrated varying results on the quality of life (QoL) of the transgender population. Therefore, the aim of this study was to conduct a systematic review and meta-analysis about the quality of life (QoL) of individuals during the post transsexual surgery period.

METHODS

We searched major biomedical electronic databases, including Scopus, Google Scholar, Psychological Information Database (PsycInfo), Web of Science, PubMed, Excerpta Medica dataBASE (EMBASE), and ProQuest, for all relevant literature published in English up to December 2019. The included papers required to be cross sectional studies that reported quality of life in people with transsexuality post surgery. After selecting eligible studies, 2 authors extracted data of each study independently and resolved any inconsistency by consensus with the third reviewer. The risk of bias was assessed by 2 independent research experts by the Newcastle-Ottawa Scale (NOS).

RESULTS

In this study, out of 497 articles extracted from the initial investigation, 8 articles with 1099 patients were ultimately selected for meta-analysis. The pooled mean of quality of life in transsexual individuals was obtained to be 70.45 (95%CI 55.87-85.03) and 59.17 (95%CI 48.59-69.74), based on World Health Organization Quality of Life (WHOQoL-BREF) and The 36-item short form of the Medical Outcomes Study questionnaire (SF36), respectively. Also, the results of the subgroup analysis for the weighted mean quality of life in male to female and female to male showed that the mean quality of life in female to male was 57.54 (95%CI 42.24-72.84) and it was 62.47 (95%CI 45.94-79.00) in male to female, based on SF36 questionnaire. Moreover, the weighted mean quality of life in female to male was 69.99 (95%CI 43.76, 96.23) and it was 70.65 (95%CI 53.11, 88.19) in male to female, based on WHOQoL-BREF questionnaire.

CONCLUSION

The results of this systematic review may support the approaches to transsexuality that facilitates sex reassignment. In this review, the means of quality of life after surgery were not compared to the means of quality of life before surgery or even before hormonal therapy which was due to inadequate number of primary studies.

Comparison of performance of specific (SLEQOL) and generic (SF36) health-related quality of life questionnaires and their associations with disease status of systemic lupus erythematosus: a longitudinal study

Background

The utility of generic health-related quality of life (HRQoL) questionnaires in patients with systemic lupus erythematosus (SLE) is uncertain. We compared the performance of generic (SF36) and specific (SLEQOL) HRQoL surveys by examining their associations with the Global Rating of Change (GRC) and SLE clinical indicators.

Methods

The study included SLE patients who attended a single-center rheumatology clinic between 2013 and 2017. Patients completed both specific (SLEQOL) and generic (SF36) surveys and rated their GRC compared to the previous visit using a 7-point Likert scale on the same day of routine visits. Based on GRC scores, patients’ change in HRQoL was categorized as “no change,” “deterioration,” or “improvement.” Disease activity (SLEDAI-2K), flare, and lupus low disease activity state (LLDAS) were assessed at each visit, and organ damage (SDI) was determined annually. Pairwise correlations between SLEQOL and SF36 components were examined, and associations between GRC status and SLE disease indicators were compared using generalized estimating equations (GEE).

Results

Three hundred thirty-seven patients with 2062 visits were included in the analysis. SLEQOL correlated significantly with SF36. Patients reported improvements in HRQoL in 58%, deterioration in 15%, and “no change” in 27% of all visits. Compared to the “no change” group, mean SF36 and SLEQOL scores were significantly lower in the deterioration group and higher in the improvement group. The magnitude of changes observed with SLEQOL and SF36 in the deterioration and improvement groups was similar. Patients in LLDAS had significantly higher mean scores in both SLEQOL and SF36. In contrast, patients with active disease, especially those with cutaneous, renal, central nervous system, and musculoskeletal activity, had significantly lower SLEQOL and SF36. Flare and organ damage were also associated with lower SLEQOL and SF36-PCS (physical component) but not with SF36-MCS (mental component).

Conclusion

SLEQOL and SF36 similarly describe HRQoL in SLE. Both instruments demonstrated strong associations with GRC-based deterioration or improvement as well as SLE disease status. LLDAS was associated with improved HRQoL.

Association Between Everyday Technology Use, Activities of Daily Living and Health-Related Quality of Life in Chronic Obstructive Pulmonary Disease

Purpose

A decline in the ability to perform activities of daily living (ADL) and ability to use everyday technology can pose threats to independent living, healthcare management and quality of life (QOL) of patients suffering from chronic obstructive pulmonary disease (COPD). Evidence of the relationship between these variables remains limited. The dual aim of this study was, first, to investigate if health-related QOL (HRQOL) was associated with quality in ADL performance and everyday technology use; second, to examine whether lung function, years with COPD diagnosis, living status or educational level affected physical and mental domains of HRQOL.

Methods

This cross-sectional study included (N=80) participants aged 46-87 years recruited at healthcare centres in the Northern Region of Denmark using a convenience sampling procedure. Data were gathered through standardized assessments and analysed using multiple regression analysis.

Results

The regression model explained 50.6% (R2=0.506) of the variation in HRQOL-physical. The following four variables were statistically significantly associated with HRQOL - physical: years since COPD diagnosis (p=0.023), ability to use everyday technology (p=0.006), amount of relevant everyday technologies (p=0.015) and ADL motor ability (p<0.01). The regression model explained 22.80% (R2=0.228) of HRQOL - mental. Only the variable ability to use everyday technology was statistically significantly associated with HRQOL - mental (p=0.009).

Conclusion

Quality of ADL performance and everyday technology use seem to be associated with HRQOL in people living with COPD. The only demographic variable associated with HRQOL was years with COPD. This indicates that healthcare professionals should enhance their attention also to ADL-performance and everyday technology use when striving to increase the HRQOL of persons living with COPD.

Validation of the Arabic version of the SF-36, generic questionnaire of quality of life related to health among the elderly in Lebanon

Background

Measuring health status of elderly is essential for the prediction of their health care needs. Health research usually considers objective outcome measure; however there is a need to increase self-reported measures of health.

Aims

The aim of this study was to assess the psychometric properties of the SF36 among a group of Lebanese elderly.

Methods

It was a cross-sectional observational study. A systematic sample of elderly people aged 60 years and more was selected from dispensary, private and governmental hospitals in Lebanon. Data were collected using face-to-face interview. The first part of the questionnaire consisted of sociodemographic characteristics. The second part consisted of the Arabic version of the SF-36. The third part consisted of Activity of Daily Living (ADL) scale, presence of health problems and number of medication consumed per day.

Results

A total of 250 elderly people were included. The mean age was 70.69±7.70 years. Cronbach alphas for all SF-36 scales exceeded 0.798. The intra-Class correlation coefficient varied between 0.675 (item 2) and 0.980 (items 14, 16 and 18) indicating good reliability. The quality of life (QoL) of women was poorer than men (p<0.001). It was significantly lesser when the number of health problems (p<0.001) and medications (p<0.001) increased, and the ADL score (p<0.05) decreased.

Conclusion

SF-36 is a valid and reliable instrument for measuring QoL among Lebanese elderly and could be used for monitoring the QoL of this population.

Food 4 Health - He Oranga Kai: Assessing the efficacy, acceptability and economic implications of Lactobacillus rhamnosus HN001 and β-glucan to improve glycated haemoglobin, metabolic health, and general well-being in adults with pre-diabetes: study protocol for a 2 × 2 factorial design, parallel group, placebo-controlled randomized controlled trial, with embedded qualitative study and economic analysis

BACKGROUND

The rates of pre-diabetes and type 2 diabetes mellitus are increasing worldwide, producing significant burdens for individuals, families, and healthcare systems. In New Zealand, type 2 diabetes mellitus and pre-diabetes disproportionally affect Māori, Pacific, and South Asian peoples. This research evaluates the efficacy, acceptability, and economic impact of a probiotic capsule and a prebiotic cereal intervention in adults with pre-diabetes on metabolic and mental health and well-being outcomes.

METHODS

Eligible adults (n = 152) aged 18-80 years with pre-diabetes (glycated haemoglobin 41-49 mmol/mol) will be enrolled in a 2 × 2 factorial design, randomised, parallel-group, placebo-controlled trial. Computer-generated block randomization will be performed independently. Interventions are capsulated Lactobacillus rhamnosus HN001 (6 × 109 colony-forming units/day) (A) and cereal containing 4 g β-glucan (B), placebo capsules (O1), and calorie-matched control cereal (O2). Eligible participants will receive 6 months intervention in the following groups: AB, AO1, BO2, and O1O2. The primary outcome is glycated haemoglobin after 6 months. Follow-up at 9 months will assess the durability of response. Secondary outcomes are glycated haemoglobin after 3 and 9 months, fasting glucose, insulin resistance, blood pressure, body weight, body mass index, and blood lipid levels. General well-being and quality of life will be measured by the Short-Form Health Survey 36 and Depression Anxiety Stress Scale 21 at 6 and 9 months. Outcome assessors will be blind to capsule allocation. An accompanying qualitative study will include 24 face-to-face semistructured interviews with an ethnically balanced sample from the β-glucan arms at 2 months, participant focus groups at 6 months, and three health professional focus groups. These will explore how interventions are adopted, their acceptability, and elicit factors that may support the uptake of interventions. A simulation model of the pre-diabetic New Zealand population will be used to estimate the likely impact in quality-adjusted life years and health system costs of the interventions if rolled out in New Zealand.

DISCUSSION

This study will examine the efficacy of interventions in a population with pre-diabetes. Qualitative components provide rich description of views on the interventions. When combined with the economic analysis, the study will provide insights into how to translate the interventions into practice.

The impact of progressive chronic kidney disease on health-related quality-of-life: a 12-year community cohort study

PURPOSE

Quality-of-life is poor in end-stage kidney disease; however, the relationships between earlier stages of chronic kidney disease (CKD) and are poorly understood. This study explored longitudinal quality-of-life changes in a community-based CKD cohort and assessed associations between CKD and quality-of-life over time, and between baseline quality-of-life and CKD outcomes.

METHODS

We used the Australian diabetes, obesity and lifestyle study-a nationally representative, prospective cohort with data collected at baseline, year 5 and year 12-to examine the relationships between CKD stage, quality-of-life and outcomes. Linear mixed regression, cox proportional hazards, Kaplan-Meier and competing risks analyses were used.

RESULTS

Of 1112 participants with CKD and baseline quality-of-life data, the physical component summary (PCS) score was significantly lower than for the general population (p = 0.01 age and sex adjusted), while the mental component summary (MCS) score was no different (p = 0.9 age and sex adjusted). In our unadjusted mixed effects model, more advanced kidney disease was associated with lower PCS and higher MCS at baseline (p < 0.001 and p < 0.01, respectively); however, this effect was no longer significant after adjustment for demographic and clinical variables. The rate of decline in PCS over the period of follow-up was greatest for those with more advanced kidney disease (p < 0.001 in unadjusted model, p = 0.007 in adjusted model). There was no association between change in MCS over the period of follow-up and severity of kidney disease in either the unadjusted or adjusted model (p = 0.7 and p = 0.1, respectively). Lower PCS, but not MCS, was associated with increased cardiovascular and increased all-cause mortality even after adjustment for key demographic and clinical variables (p < 0.001).

CONCLUSIONS

Physical, but not mental, quality-of-life is significantly impaired in CKD, and continues to decline with disease progression.

A multicenter study investigating the molecular fingerprint of psychological resilience in breast cancer patients: study protocol of the SCAN-B resilience study

Background

Individual patients differ in their psychological response when receiving a cancer diagnosis, in this case breast cancer. Given the same disease burden, some patients master the situation well, while others experience a great deal of stress, depression and lowered quality of life. Patients with high psychological resilience are likely to experience fewer stress reactions and better adapt to and manage the life threat and the demanding treatment that follows the diagnosis. If this phenomenon of mastering difficult situations is reflected also in biomolecular processes is not much studied, nor has its capacity for impacting the cancer prognosis been addressed.

This project specifically aims, for the first time, to investigate how a breast cancer patient’s psychological resilience is coupled to biomolecular parameters using advanced “omics” and, as a secondary aim, whether it relates to prognosis and quality of life one year after diagnosis.

Method

The study population consists of newly diagnosed breast cancer patients enrolled in the Sweden Cancerome Analysis Network – Breast (SCAN-B) at four hospitals in Sweden. At the time of cancer diagnosis, the patient fills out the standardized method to measure psychological resilience, the “Connor-Davidson Resilience scale” (CD-RISC), the quality of life measure SF-36, as well as providing social and socioeconomic variables. In addition, one blood sample is collected. At the one-year follow-up, the patient will be subjected to the same assessments, and we also collect information regarding smoking, exercise habits, and BMI, as well as patients’ trust in the treatment and their satisfaction with the care and treatment.

Discussion

This explorative hypothesis-generating project will pave the way for larger validation studies, potentially leading to a standardized method of measuring psychological resilience as an important parameter in cancer care. Revealing the body-mind interaction, in terms of psychological resilience and quality of life, will herald the development of truly personalized psychosocial care and cancer intervention treatment strategies.

Psychological distress increases the risk of falling into poverty amongst older Australians: the overlooked costs-of-illness

Background

This paper aimed to identify whether high psychological distress is associated with an increased risk of income and multidimensional poverty amongst older adults in Australia.

Methods

We undertook longitudinal analysis of the nationally representative Household Income and Labour Dynamics in Australian (HILDA) survey using modified Poisson regression models to estimate the relative risk of falling into income poverty and multidimensional poverty between 2010 and 2012 for males and females, adjusting for age, employment status, place of residence, marital status and housing tenure; and Population Attributable Risk methodology to estimate the proportion of poverty directly attributable to psychological distress, measured by the Kessler 10 scale.

Results

For males, having high psychological distress increased the risk of falling into income poverty by 1.68 (95% CI: 1.02 to 2.75) and the risk of falling into multidimensional poverty by 3.40 (95% CI: 1.91 to 6.04). For females, there was no significant difference in the risk of falling into income poverty between those with high and low psychological distress (p = 0.1008), however having high psychological distress increased the risk of falling into multidimensional poverty by 2.15 (95% CI: 1.30 to 3.55). Between 2009 and 2012, 8.0% of income poverty cases for people aged 65 and over (95% CI: 7.8% to 8.4%), and 19.5% of multidimensional poverty cases for people aged 65 and over (95% CI: 19.2% to 19.9%) can be attributed to high psychological distress.

Conclusions

The elevated risk of falling into income and multidimensional poverty has been an overlooked cost of poor mental health.

Hysterectomy and perceived physical function in middle-aged Australian women: a 20-year population-based prospective cohort study

PURPOSE

Hysterectomy is one of the most common gynaecological procedures worldwide. Changes in endocrine function may impact age-associated decline in physical function and these changes may be accelerated by hysterectomy. The aim of this study was to investigate associations between hysterectomy status and self-reported physical function limitations.

METHODS

Our study sample (n = 8624) came from the mid-cohort (born 1945-1950) of the Australian Longitudinal Study on Women's Health (ALSWH). Self-report of physical function was measured by the Physical Functioning (PF) subscale of the Medical Outcomes Study Short Form Health Survey (SF-36) over seven surveys (1998-2016), categorised into substantial, moderate and minimal PF-limitations. The associations between hysterectomy status and de novo substantial or moderate PF-limitations versus minimal PF-limitations were investigated using log-multinomial regression.

RESULTS

By Survey 8 (2016), 20% of the study sample had a hysterectomy with ovarian conservation (hysterectomy only) and 9% had a hysterectomy and both ovaries removed (hysterectomy-bilateral oophorectomy). Women with a hysterectomy only had a small increase in risk of substantial PF-limitations (versus minimal PF-limitations) compared to women with no hysterectomy (relative risk [RR]: 1.13; 95% confidence interval [95% CI] 1.00-1.27); the point estimate was stronger for women with a hysterectomy-bilateral oophorectomy (RR: 1.26; 95% CI 1.09-1.46). In a supplementary analysis, the increased risk of substantial PF-limitations was seen only in women who had surgery before the age of 45 years.

CONCLUSIONS

Compared to women with no hysterectomy, women with hysterectomy-bilateral oophorectomy were at increased risk of substantial PF-limitations versus minimal PF-limitations over 18 years of follow-up.

Pain, psychosocial tests, pain sensitization and laparoscopic pelvic surgery

BACKGROUND AND AIMS

Individuals with non-acute pain are challenged with variable pain responses following surgery as well as psychological challenges, particularly depression and catastrophizing. The purpose of this study was to compare pre- and postoperative psychosocial tests and the associated presence of sensitization on a cohort of women undergoing elective laparoscopic surgery for non-acute pain defined as pain sufficient for surgical investigation without persistent of chronic pain.

METHODS

The study was a secondary analysis of a previous report (Am J Obstet Gynecol 2014 Oct;211(4):360-8.). The study was a prospective cohort trial of 77 women; 61 with non-acute pain and 16 women for a tubal ligation. The women had the following tests: Pain Disability Index, Pain Catastrophizing Scale, CES-D (Center for Epidemiologic Studies Depression Scale) depression scale and the McGill Pain Scale (short form) as well as their average pain score and the presence of pain sensitization. All test scores were correlated together and comparisons were done using paired t-test.

RESULTS

There were reductions in pain and psychosocial test scores that were significantly correlated. Pre-operative sensitization indicated greater changes in psychosocial tests.

CONCLUSIONS

There was a close association of tests of psychosocial status with average pain among women having surgery on visceral tissues. Incorporation of these tests in the pre- and postoperative evaluation of women having laparoscopic surgery appears to provide a means to a broader understanding of the woman's pain experience.

Postoperative Evaluation of Health-Related Quality-of-Life (HRQoL) of Patients With Lumbar Degenerative Spondylolisthesis After Instrumented Posterolateral Fusion (PLF): A prospective Study With a 2-Year Follow-Up

Background

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.

Methods

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.

Results

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.

Conclusion

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.

Health-Related Quality of Life in Adults with Osteogenesis Imperfecta

Osteogenesis imperfecta (OI) is a systemic connective tissue disorder most often caused by mutations in collagen type 1 related genes. Patients with OI suffer from multiple fractures and various degrees of growth deficiency and bone deformity. It is unknown whether the systemic effect of defect collagen type 1 influences the quality of life in patients with OI. We therefore aimed to investigate health-related quality of life (HRQoL) in a well-characterized cohort of adult patients with OI. We included 85 adult patients with mild to severe OI (types I, III, and IV) and obtained information about skeletal- and non-skeletal phenotypes and patient demographics. We investigated physical and mental HRQoL using a validated questionnaire, SF-36, and compared the data to values obtained in a population without OI. Patients with mild, moderate, and severe OI all had lower mean scores on domains describing physical HRQoL and a lower mean physical component score compared to the general population, p < 0.001. Patients with severe OI had lower mean scores on physical HRQoL, p < 0.05. The scores on domains reflecting mental HRQoL were more inhomogenously affected, but did not differ significantly from the general population. OI has an impact on physical and some aspects of mental HRQoL. The scores on physical health were correlated to severity of the OI disease. The mental component score in the OI patients was unaffected and comparable with the general population.

Assessment of quality of life in patients with post kalaazar dermal leishmaniasis

Background

Post kala-azar dermal leishmaniasis (PKDL) is a dermatological disorder caused by protozoal parasite Leishmania donovani. PKDL cases are thought to be a reservoir of parasites and may increase cases of visceral leishmaniasis. The disease is not life threatening but cosmetic disfigurement associated with it may impair the patients’ quality of life. This study aimed to assess the health related quality of life in patients with post kalaazar dermal leishmanasis for the first time.

Methods

A total of 92 PKDL cases and 96 healthy participants filled out the questionnaires. The Dermatology Life Quality Index (DLQI) and SF 36 questionnaire were used to assess the quality of life. Data on socio-demographic and clinical features were also collected. The collected data were analyzed by using SPSS software (version 16), Student’s t-test, analysis of variance (ANOVA) was applied for comparison of means.

Results

PKDL patients experienced very large impact on their quality of life. The mean score of DLQI was 11.41. Highest impact was found in symptoms and feelings and lowest impact was observed for personal relationship domain. Patients below 20 years age group found to have lower quality of life. There was a significant difference in mean DLQI scores with regard to age and severity of lesions (P < 0.05). No significant difference was observed with respect to gender, duration and location of lesions (p > 0.05).

Conclusion

PKDL significantly impaired the patient’s quality of life. Further studies to assess the impact of treatment on quality of life in these patients are recommended.

Quality of life of patients treated for giant cell arteritis: a case-control study

The objective of the study was to assess the quality of life (QOL) of patients with giant cell arteritis (GCA), following high dose of corticosteroids (CS). Thirty patients with GCA who had stopped CS or who were under long-term low dose of CS were included and matched to 60 controls. QOL was measured by the SF-36 score and a specific questionnaire. GCA patients had no impairment of QOL compared to controls according to SF-36. Most of them (57%) estimated that their general condition was improved following treatment. Patients with GCA complications or CS therapy side effects had no significant impairment of their QOL compared with patients without complications or adverse effects. Only the patients who had gained weight had a lower score on the domain "Vitality" (VT; p = 0.013). Walking difficulties were the most frequent complaints. They were associated with impaired scores on the physical summary score (p = 0.0340) and on the "General Health" (GH; p = 0.005) and "Physical Functioning" (PF, p = 0.0298) domains. Falls among GCA patients were associated with altered scores on the domain VT (p = 0.0058) and on the mental summary score if they had fallen at least three times (p = 0.0460). GCA patients following high dose of CS or under long-term low doses of CS have no significant impairment of their QOL compared to controls. GCA complications, including visual impairment, do not seem to have any major impact on QOL.

Arterial Hypertension and Health-Related Quality of Life

PURPOSE

To investigate the effect of awareness of arterial hypertension on quality of life in hypertensive patients in Greece.

MATERIALS AND METHODS

This was a prospective observational study that included 189 aware hypertensive patients on treatment with antihypertensive therapy. Patients were ambulatory men or women ≥18 years old, with diagnosed essential hypertension. The administration and fulfillment of the questionnaires was given at the outpatient hypertensive clinic starting with the SF-36 and continuing with the BDI-I test.

RESULTS

The mean BDI score was 9.9 ± 6.9, and 58, 25, 8.9, and 7.3% were identified as without, with minimal, moderate, and 0.8% with severe depression, respectively. The mean score for physical component summary (PCS-36) was 48.9 ± 7.6, and the mean score for mental component summary (MCS-36) was 46.0 ± 10.6. The stage of hypertension was not an independent predictor for any of the SF-36 dimensions. Dippers had not different levels of health-related quality of life (HRQOL) as compared with non-dippers. LV hypertrophy was associated with lower scores on bodily pain (p < 0.05) and kidney failure was associated with lower scores on general health perception (p < 0.05). Female gender, increased age, and the presence of COPD were independently associated with lower physical and mental health scores (p < 0.05). Score on BDI independently correlated with all dimensions of SF-36, indicating that greater depression levels are associated with lower levels of HRQOL.

CONCLUSION

The stage as well as awareness of arterial hypertension does not affect physical and mental health. The fact that arterial hypertension per se is not a symptomatic disease may explain these results at least in patients with uncomplicated hypertension.

Factors determining fatigue in the chronic fatigue syndrome: a path analysis

OBJECTIVES

To explore the interrelationship of different dimensions (fatigue, neuroticism, sleep quality, global mental and physical health) in patients with chronic fatigue syndrome (CFS).

METHODS

Patients meeting the Fukuda criteria of CFS filled out two independent fatigue scales (Fatigue Questionnaire, FQ and Checklist Individual Strength, CIS), NEO-Five Factor Inventory (NEO-FFI), Pittsburgh Sleep Quality Index (PSQI) and Medical Outcomes Study 36-item Short Form Health Survey (SF36). Exploratory and confirmatory path analyses were performed.

RESULTS

Out of 226 eligible patients, 167 subjects were included (mean age 39.13 years, SD 10.14, 92% female). In a first exploratory path analysis, using FQ for assessment of fatigue, night-time PSQI sleep quality had a direct effect on SF36 physical quality of life (PQoL) and no effect on FQ fatigue. This was confirmed by a subsequent path analysis with CIS fatigue and by confirmatory path analyses in 81 patients. These unexpected results raised the question whether FQ or CIS fatigue sufficiently operationalizes fatigue in CFS patients.

CONCLUSIONS

Poor sleep quality seems to directly impact on mental quality of life (MQoL) and PQoL without mediation of fatigue assessed with FQ and CIS. A more cohesive framework needs to be developed with more comprehensive clinical tools for the different dimensions in the construct of CFS.

Greener living environment healthier people?: Exploring green space, physical activity and health in the Doetinchem Cohort Study

BACKGROUND

Evidence is emerging that more green space in the living environment is associated with better health, partly via the pathway of physical activity.

OBJECTIVES

We explored the cross-sectional and longitudinal associations between green space and physical activity and several health indicators in the Doetinchem Cohort Study.

METHODS

A random sample of men and women aged 20-59years at baseline was measured max 5 times with 5year-intervals in the period 1987-2012. Data of round 3-5 were used. Measurements were based on examinations (height, weight, blood pressure) or questionnaires (physical activity, perceived health, depressive symptoms, chronic conditions). The percentage of green space (mainly urban and agricultural green) around the home address (125m and 1km) was calculated using satellite data.

RESULTS

More agricultural green was associated with less time spent on bicycling (β1km=-0.15, 95%CL -0.13; -0.04) and sports (β1km=-0.04, 95%CL -0.07; -0.01) and more time spent on gardening (β1km=0.16, 95%CL 0.12; 0.19) and odd jobs (β1km=0.10, 95%CL 0.05; 0.15), and this was in the other direction for urban green. For only a few of the many health indicators a positive association with green was found, and mainly for total green within 1km radius. Longstanding green or a transition to more green did not show more pronounced associations with health.

CONCLUSIONS

For the green space range of the Doetinchem area the findings do not strongly support the hypothesis that the percentage of green in the living environment affects health positively. The distinction by type of green may, however, be relevant for physical activity.

Twelve-week exercise training and the quality of life in menopausal women - clinical trial

INTRODUCTION

The menopause transition is associated with decreased health functioning. About 80-90% of women experience mild to severe physical or physiological menopause-related complaints per year when approaching menopause. Physical activity may reduce some climacteric symptoms and improve the quality of life.

AIM OF THE STUDY

Aim of the study was to investigate the influence of a 12-week training programme on the quality of life (QoL) in menopausal-aged women living in a rural area.

MATERIAL AND METHODS

Participants were 80 women aged 40-65 years and divided into two randomly selected groups in training sessions (exercising group, n = 40 and control group, n = 40). SF36 was used to assess the quality of life in both groups before and after 12 weeks. Exercising women participated in training session 3 times a week. Each 60-minute exercise session included warming-up exercises, walking, stretching, strengthening exercises with an elastic band and cooling down exercises.

RESULTS

A non-significant positive difference in all SF36 domains in the exercising group was observed. The results of the study showed a statistically significant higher QoL in the exercising group compared to the control group after 12-week training in two domains: vitality and mental health. The improvement in the quality of life in the study group was 0.19 points (role limits - physical domain, least change) and 4.96 (vitality domain, most change).

CONCLUSIONS

Controlled and regular exercise for 12 weeks was significantly correlated with a positive change in vitality and mental health. Sedentary women should consider modification of their lifestyle to include physical activity as it leads to improvement of their quality of life.

Quality of life of patients with fibrodysplasia ossificans progressiva

INTRODUCTION

Fibrodysplasia ossificans progressiva (FOP) is a rare disorder characterized by episodes of acute pain and heterotopic ossification of soft tissue, and progressively limited physical function and social participation.

OBJECTIVE

We aimed to determine the impact of FOP on quality of life, specifying areas or dimensions most affected.

MATERIALS AND METHODS

This was a transverse observational study; patients with FOP were assessed using the Short Form 36. Questionnaire results were obtained using Quality Metric software and analyzed using frequency distribution, percentages and measures of central tendency.

RESULTS

Eight patients, mean age 30.2 years, were included. The physical dimension was the most affected, with an average of 25.5 points. The most representative items were impaired function and physical role. Physical pain was found with an average of 44.5 points. The best scores were reported in the areas of emotional role and mental health, with an average of 79 and 76 respectively.

CONCLUSIONS

FOP is a severely disabling disease, generating a significant deterioration in quality of life secondary to progressive deterioration in physical abilities. The findings of this study demonstrate good self-rated health of participants.

Psychological distress and the increased risk of falling into poverty: a longitudinal study of Australian adults

PURPOSE

To identify whether psychological distress is associated with an increased risk of falling into poverty, giving a more complete picture of how psychological distress affects living standards.

METHODS

Longitudinal analysis of the nationally representative Household Income and Labour Dynamics in Australian (HILDA) survey using Poisson regression models to estimate relative risk of falling into income poverty and multidimensional poverty between 2007 and 2012. The sample was limited to those who were not already in income poverty in 2007. Psychological distress was identified using the Kessler-10 (K10) scale.

RESULTS

After adjusting for confounding factors, having moderate psychological distress increased the risk of falling into income poverty by 1.62 (95% CI 1.31-2.01, p < 0.0001) and the risk of falling into multidimensional poverty by 1.85 (95% CI 1.37-2.48, p < 0.0001); having very high psychological distress increased the risk of falling into income poverty by 2.40 (95% CI 1.80-3.20, p < 0.0001) and the risk of falling into multidimensional poverty by 3.68 (95% CI 2.63-5.15, p < 0.0001), compared to those with low psychological distress. Those who did experience income poverty (RR: 1.29, 95% CI 1.04-1.61, p = 0.0210) and those who experienced multidimensional poverty (RR: 1.69, 95% CI 1.32-2.17, p < 0.0001) had an increased risk of having their level of psychological distress increase further compared to those who did not experience poverty.

CONCLUSION

To date, the increased risk of falling into poverty that is associated with elevated levels of psychological distress has been an overlooked burden of the condition.

Analysis of associations between congenital heart defect complexity and health-related quality of life using a meta-analytic strategy

BACKGROUND

As a consequence of heterogeneous results of relatively small individual trials, the impact of congenital heart defects (CHD) and the effect of disease severity on patient reported outcome measures (PROs) of quality of life (QoL) remains uncertain. We aimed to systematically summarize QoL data in CHD patients using meta-analytic methods.

METHODS AND RESULTS

We performed a systematic review of the literature focusing on QoL in CHD. The search yielded 234 publications meeting the inclusion criteria, with a median of 88 patients per study (46% females, average age 24years). In total, QoL was reported using PROs in 47,471 CHD-patients. More than 95 different PROs were used to evaluate QoL. The most commonly used tool was the SF36 form (69 publications). Analysis of available quantitative QoL data from SF36 publications (n=4217 CHD patients) showed that QoL was reduced in patients with moderate or complex cardiac disease (e.g. relative physical functioning scores 0.96 [0.93-0.99] and 0.91 [0.88-0.95] compared with controls), while no such effect was evident in those patients with simple cardiac lesions. Similar results were found for the general health domain of the SF36 domain.

CONCLUSIONS

Despite the proliferation of QoL-studies in CHD no standardized approach for measuring and reporting QoL has emerged and the published results are heterogeneous. In aggregation, however, the results of this study suggest that QoL is impaired in moderate or complex CHD, while no such impact of CHD on QoL could be established--on average--in patients with simple defects.

Effects of a Short Physical Exercise Intervention on Patients with Multiple Sclerosis (MS)

BACKGROUND

The aim of this prospective randomized controlled trial was to investigate if a short-term endurance or combined endurance/resistance exercise program was sufficient to improve aerobic capacity and maximum force in adult patients (18-65 years) with multiple sclerosis (MS).

METHODS

All patients performed a three-month exercise program consisting of two training sessions per week, lasting 40 min each, with moderate intensity. All patients had a maximum value of 6 (low to moderate disability) on the Expanded Disability Status Scale (EDSS). One group (combined workout group (CWG); 15 females, 4 males) completed a combined endurance/resistance workout (20 min on a bicycle ergometer, followed by 20 min of resistance training), while the other group (endurance workout group (EWG); 13 females, 5 males) completed a 40 min endurance training program. Aerobic capacity was assessed as peak oxygen uptake, ventilatory anaerobic threshold, and workload expressed as Watts. Maximum force of knee and shoulder extensors and flexors was measured using isokinetic testing. Quality of life was assessed with the SF-36 questionnaire, and fatigue was measured using the Modified Fatigue Impact Scale.

RESULTS

Both training groups increased in aerobic capacity and maximum force. EWG, as well as CWG, showed improvement in several subscales of the SF-36 questionnaire and decrease of their fatigue.

CONCLUSION

A short exercise intervention increased both aerobic capacity and maximum force independent of whether endurance or combined endurance/resistance workouts were performed.

How to interpret multidimensional quality of life questionnaires for patients with schizophrenia?

PURPOSE

The classification of patients into distinct categories of quality of life (QoL) levels may be useful for clinicians to interpret QoL scores from multidimensional questionnaires. The aim of this study had been to define clusters of QoL levels from a specific multidimensional questionnaire (SQoL18) for patients with schizophrenia by using a new method of interpretable clustering and to test its validity regarding socio-demographic, clinical, and QoL information.

METHODS

In this multicentre cross-sectional study, patients with schizophrenia have been classified using a hierarchical top-down method called clustering using unsupervised binary trees (CUBT). A three-group structure has been employed to define QoL levels as "high", "moderate", or "low". Socio-demographic, clinical, and QoL data have been compared between the three clusters to ensure their clinical relevance.

RESULTS

A total of 514 patients have been analysed: 78 are classified as "low", 265 as "moderate", and 171 as "high". The clustering shows satisfactory statistical properties, including reproducibility (using bootstrap analysis) and discriminancy (using factor analysis). The three clusters consistently differentiate patients. As expected, individuals in the "high" QoL level cluster report the lowest scores on the Positive and Negative Syndrome Scale (p = 0.01) and the Calgary Depression Scale (p < 0.01), and the highest scores on the Global Assessment of Functioning (p < 0.03), the SF36 (p < 0.01), the EuroQol (p < 0.01), and the Quality of Life Inventory (p < 0.01).

CONCLUSION

Given the ease with which this method can be applied, classification using CUBT may be useful for facilitating the interpretation of QoL scores in clinical practice.

Patient reported allergies are a risk factor for poor outcomes in total hip and knee arthroplasty

We evaluated 459 patients undergoing THA or TKA who completed preoperative and postoperative WOMAC and/or SF36 surveys. Medical comorbidities and reported allergies were also recorded. Evaluation of surveys was compared for patients with or without 4 or more reported allergies using statistical methods. Patients with 4 or more reported allergies had less improvement on SF36 Physical Component Score (∆PCS=4.2) than those with 0-3 allergies (∆PCS=10.0, P=0.0002). Regression analysis showed that this change was independent of self-reported comorbidities. Patients reporting 4 or more allergies also had less improvement in WOMAC function (∆F=21.4) than those with 0-3 allergies (∆F = 27.2, P=0.036). Similar nonsignificant trends occurred in SF36 mental and WOMAC pain and stiffness scores.

Quality of life in a cohort of high-dose benzodiazepine dependent patients

BACKGROUND

Benzodiazepines (BZD) are among the most widely prescribed drugs in developed countries. Since BZD can produce tolerance and dependence even in a short time, their use is recommended for a very limited time. However, these recommendations have been largely disregarded. The chronic use of BZD causes a number of serious side effects, i.e., cognitive impairment, falls, traffic accidents, dependence and tolerance. The aim of the present study was to evaluate quality of life (QoL) in a cohort of 62 consecutive high-dose BZD-dependent patients seeking a BZD detoxification.

METHODS

Patients seeking BZD detoxification were evaluated using the General Health Questionnaire (GHQ-12) and the short form-36 questionnaire (SF-36).

RESULTS

Patients showed a significant reduction of QoL as measured by either SF-36 or GHQ-12. In particular, the greater impairment was observed in the items exploring physical and emotional status. Physical functioning was the item more influenced by the length of BZD abuse. Female patients showed a greater reduction of QoL compared to male, at least in some of the explored items. Social functioning scores were greatly reduced.

CONCLUSIONS

The present study shows for the first time that high-doses BZD dependent patients have a reduced QoL and a reduced social functioning, along with high levels of psychological distress.

Health-related quality of life and severity of fatigue in HIV/HCV co-infected patients before, during, and after antiviral therapy with pegylated interferon plus ribavirin

The aim of this study was to prospectively assess health-related quality of life (HRQL) and severity of fatigue before, during and after antiviral therapy in HIV/HCV co-infected patients.

DESIGN

59 HIV/HCV co-infected patients receiving pegylated interferon plus ribavirin (PEGIFN+RBV) in the HIVCOPEG study were included in this substudy evaluating the secondary endpoints HRQL and severity of fatigue.

METHODS

HRQL and severity of fatigue were assessed using SF36 and FSS, respectively. Advanced liver fibrosis was defined as METAVIR F3/F4 or liver stiffness >9.5 kPa.

RESULTS

At baseline, advanced liver fibrosis was associated with worse physical health. Mental health was impaired in female patients and in patients with a history of intravenous drug abuse, while a history of depression was associated with higher severity of fatigue. Female gender was associated with a more pronounced relative decrease in mental health during therapy. At follow-up, 24 weeks after the end of therapy, both physical health and fatigue symptoms had improved. Virological response was associated with better physical and mental health, as well as with reduced severity of fatigue. A correlation between anemia grade and the relative impairments in physical health, mental health and fatigue was observed.

CONCLUSIONS

Antiviral therapy with PEGIFN+RBV impairs physical and mental health and increases severity of fatigue, while virological response is associated with improvements in physical health and fatigue symptoms. The optimization of anemia management is essential for reducing the burden of impaired HRQL and fatigue in HIV/HCV co-infected patients receiving antiviral therapy with PEGIFN+RBV.

Fragrance allergy and quality of life - development and validation of a disease-specific quality of life instrument

BACKGROUND

Fragrance allergy is a lifelong condition that may give rise to permanent or recurrent contact dermatitis and may affect quality of life (QoL). The effect on QoL has not yet been investigated, and no disease-specific QoL instrument for fragrance allergy exists.

OBJECTIVE

To develop and validate a disease-specific instrument to investigate QoL among fragrance-allergic subjects.

METHOD

A fragrance QoL instrument (FQL index) was developed on the basis of narratives from 68 fragrance-allergic subjects, and consisted of 13 items. It was tested in a postal survey among 1650 participants patch tested at Gentofte University Hospital (2000-2010). The survey included other QoL instruments [Dermatology Life Quality Index (DLQI) and Short Form 36 (SF36) version 2] and questions on eczema severity (response rate of 66%). A retest was conducted after 3-6 months (response rate of 72.5%).

RESULTS

The FQL index showed a significant and strong correlation with the DLQI (rS  = 0.70), and disease severity, but a weak correlation with SF36 [mental component summary score, rS  = - 0.22; physical component summary score, rS  = - 0.31]. Good reliability and responsiveness to changes in disease severity were seen.

CONCLUSION

The FQL index is a good instrument with which to investigate QoL in subjects with fragrance allergy. Good correlations with the DLQI and self-estimated disease severity were seen, and it showed good reliability, reproducibility and ability to distinguish changes in disease severity.

Long-term functional results after short-segment pedicle fixation of thoracolumbar fractures

PURPOSE

A retrospective study to assess the health-related quality of life in patients undergoing posterior fixation of thoracolumbar fractures, and to compare the outcome with norm scores and HRQL in patients undergoing surgical treatment for degenerative conditions of the spine.

METHODS

The study population consisted of 93 consecutive patients surgically treated for a thoracolumbar fracture from 2005 to 2009. All patients underwent posterior pedicle screw fixation and fusion. 83 patients were available for follow-up. Three questionnaires reflecting health-related quality of life (HRQL) were mailed to the patients: SF-36, ODI, and EQ-5D.

RESULTS

52 men and 31 women were operated with an average age at the time of surgery of 46 years. All fractures were AO-type A3.1 and A3.2 with L1 being the primary fracture level. All patients were neurologically intact; Frankel E. The overall response rate on the questionnaires was 75% with no significant differences between responders and non-responder on basic demographic characteristics. The median follow up period was 3.8 years (range 2-6 years). The scores on all three questionnaires were significantly reduced compared to the national norm scores (p<0.05).

CONCLUSION

Health-related quality of life is affected several years after short segment posterior instrumentation of thoracolumbar fractures without neurological deficit.

Quality of life at age 18 years after extremely preterm birth in the post-surfactant era

OBJECTIVES

To assess the self-reported quality of life, health status, self-esteem, and functional outcomes at age 18 years of extremely preterm (EP; <28 weeks gestation) or extremely low birth weight (ELBW; birth weight <1000 g) adolescents born in 1991-1992 compared with normal birth weight (birth weight >2499 g) controls, and, within the EP/ELBW cohort, to assess whether these outcomes are related to gestational age or birth weight.

STUDY DESIGN

Self-reported measures of quality of life, health status, self-esteem, and functional outcomes were obtained at age 18 years from a geographic cohort of all survivors born EP/ELBW in 1991-1992 in the state of Victoria, Australia, along with matched normal birth weight controls.

RESULTS

Data were available from 194 EP/ELBW and 148 control adolescents. EP/ELBW adolescents reported similar overall quality of life, health status, and self-esteem as controls (P > .05). Birth at younger gestational age or lower birth weight were not related to poorer quality of life within the EP/ELBW cohort (P > .05). EP/ELBW adolescents reported less physical activity (OR, 0.5; 95% CI, 0.3-0.8; P < .01), sexual activity (OR, 0.6; 95% CI, 0.4-0.9; P = .01), and alcohol intake (OR, 0.5; 95% CI, 0.3-0.8; P = .01) compared with controls. Other aspects of risk-taking behavior were similar in the 2 groups (P > .05).

CONCLUSION

EP/ELBW individuals born after the introduction of exogenous surfactant are transitioning well into young adulthood, despite the fact that more of the tiniest and most immature infants survive than ever before. They report similar quality of life, self-esteem, and social and risk-taking behaviors as controls.

Sexual Dysfunction, Depression and Quality of Life in Patients With HIV Infection

OBJECTIVE

In Iran, psychological aspect of HIV infection is poorly understood. The purposes of this study were to evaluate sexual dysfunction, depression rate and health-related quality of life and evaluate the association between sexual dysfunction, depression and quality of life in a group of HIV(+) subjects in Shiraz, Iran.

METHODS

In this cross-sectional study, 278 male HIV-positive patients who had referred to voluntary counseling and testing and methadone maintenance therapy centers were recruited based on convenience sampling from May to October 2010. The purpose of the study was explained and interested individuals provided informed consent and completed validated questionnaires [Medical Outcomes Study Short Form-36 (SF-36(, Brief Male Sexual Function Inventory (BMSFI), Beck Depression Inventory-short form(BDI)] to assess overall health related quality of life (HRQOL), sexual function, and depression.

RESULTS

Average age of the participants was 34.9 ± 10.7 years and 37.5% were severely depressed. Ordinal logistic regression indicated that sexual drive (-0.15; CI: -0.28 to -0.027), ejaculation (-1.91, CI: -2.71 to -1.12), and problem assessment (-0.098, CI: -0.17 to -0.02) had significant effect on depression type. Depression was significantly correlated with poorer quality of life in all domains. Pearson's correlation coefficients between the BMSFI and the domains of SF-36 indicated that sexual drive (r= 0.215), ejaculation (r= 0.297) and problem assessment (r= 0.213) were significantly correlated with emotional wellbeing.

CONCLUSION

Sexual function and depression showed association with quality of life. Effective treatment of depression and sexual function may improve the quality of life of HIV-infected person.

Which clinical variable influences health-related quality of life the most after spontaneous subarachnoid hemorrhage? Hunt and Hess scale, Fisher score, World Federation of Neurosurgeons score, Brussels coma score, and Glasgow coma score compared

OBJECTIVE

To determine the strength of the correlation between the Hunt and Hess scale, Fisher score, Brussels coma score, World Federation of Neurosurgeons score, and Glasgow coma score and health-related quality of life.

METHODS

Evaluable questionnaires from 236 patients (5.6 years [± standard deviation, 2.854 years] on average after hemorrhage) were included in the analysis. Quality of life was documented using the MOS-36 item short form health survey. Because of the ordinal nature of the variables, Kendall tau was used for calculation. Significance was established as P ≤ 0.05.

RESULTS

Weak and very weak correlations were found in general (r ≤ 0.28). The strongest correlations were found between the Glasgow coma score and quality of life (r = 0.236, P = 0.0001). In particular, the "best verbal response" achieved the strongest correlations in the comparison, at r = 0.28/P = 0.0001. The Fisher score showed very weak correlations (r = -0.148/P = 0.012). The Brussels coma score (r = -0.216/P = 0.0001), Hunt and Hess scale (r = -0.197/P = 0.0001), and the World Federation of Neurosurgeons score (r = -0.185/P = 0.0001) revealed stronger correlations, especially in terms of the physical aspects of quality of life.

CONCLUSIONS

The Glasgow coma scale revealed the strongest, and the Fisher score showed the weakest correlations. Thus the Fisher score, as an indicator of the severity of a hemorrhage, has little significance in terms of health-related quality of life.
