Abstract
Background Physiotherapy is usually the first line of treatment for musculoskeletal disorders. If pain persists, an appointment with an orthopaedic surgeon is indicated, but many disorders for which patients are placed on orthopaedic waiting lists cannot be treated in an orthopaedic clinic. Specialised manual therapy, although not mainstream, can be an effective alternative to orthopaedic care, although its cost-effectiveness beyond 12 months is unknown. Objectives To perform an 8-year follow-up of the quality of life and costs of specialised manual therapy versus standard orthopaedic care for working-age patients with common nonsurgical musculoskeletal disorders referred to orthopaedic surgeons and to develop a health economic model. Design Cost-effectiveness study using Markov modelling. Methods The index group of a previously published pragmatic randomised controlled trial received a maximum of five treatment sessions of specialised manual therapy, while the control group received orthopaedic 'care as usual'. At 3, 6, 12 and 96 months, Health-Related Quality of Life and costs were measured with Short Form Health Survey 36, Short Form Health Survey 6D and Diagnostic Related Groups. An incremental cost-effectiveness ratio was calculated, a Markov model was developed and a sensitivity analysis was performed. Results Overall, 95% (n = 75) of the participants completed the 8-year follow-up. Recovery rates during the first 3 months ('per protocol') in the index and control group were 69% and 58%, respectively. The index group had 0.159 more gains in quality-adjusted life years and cost 40,270 SEK (€4027) less per patient over 8 years. The sensitivity analysis results were consistent with the main results. Conclusion Specialised manual therapy dominated standard care after 8 years. The results of this small but very first study are promising; therefore, further exploration within other health care professions, clinics and/or countries is required. Our study raises questions about the triaging of orthopaedic outpatients, cost-effectiveness and resource allocation. Registration Not applicable per the information provided by ClinicalTrials.gov. Plain Language Summary Specialised manual therapy is more cost-effective than 'care as usual' for working-age patients referred to an orthopaedist. This study provides an 8-year follow-up of the cost effects and quality of life of a previously published trial. Why was this study conducted? The standard care for musculoskeletal pain consists of exercises with a physiotherapist in primary care. If the pain persists, a referral to an orthopaedic clinic is often made. Many of these referrals are inappropriate because they concern pain from muscles and joints that do not benefit from surgery or the resources available in an orthopaedic clinic. There is a gap in competence and treatment between primary and specialised care that is costly, time- and resource-consuming and causes prolonged patient suffering. Although specialised manual therapy (MT) is effective, its use is not mainstream. Costs and effects after more than 12 months of treatment that may shorten waiting lists have never been evaluated. What did the researchers do? Quality of life and costs were compared in 75 patients with nonsurgical disorders referred to orthopaedic surgeons at 8 years after treatment with specialised MT or standard orthopaedic care. A health economics model for the probability of recovery was also developed and tested. What did the researchers find? Compared with the control group, the study participants treated with specialised MT had a better quality of life, required fewer health care interventions, underwent less surgery, incurred significantly lower costs and demonstrated an increased probability of recovery. What do these findings mean? It seems probable that using specialised MT for an old, well-known structural problem may yield better treatment effects at a significantly lower cost. Our study findings suggest that policy recommendations should focus on costs and effects rather than resource utilisation alone. The study is small and requires expansion using its economic health model.

Abstract
Introduction A systematic review is conducted in the study to investigate the relationship between telework and organizational economic performance indicators such as self-reported employee performance, organizational performance, actual employee turnover rates, or intentions. Methods The databases Scopus, Business Source Premier, and Web of Science were used to conduct a literature search. Original articles published from 2000 and up to May 2021 were selected. Studies were screened for inclusion independently by review pairs and data were extracted. The Mixed Methods Appraisal Tool (MMAT) was used to evaluate the quality of the studies included. Results Forty-three studies were included with some addressing multiple outcomes. Self-reported performance was higher for teleworking employees compared to those working in the ordinary workplace. The extent of the change in performance was dependent on individual characteristics and the extent of the teleworking practice in the organization. Telework was also associated with increased organizational performance, particularly in homogenous samples with unique work tasks. When telework is voluntary, it appears that both actual employee turnover rates and intentions to leave the organization are lower. Discussion Further research with high-quality prospective designs is necessary to properly understand the contribution of telework to organizational economic performance indicators.

Abstract
BACKGROUND Low back and neck pain are the most common musculoskeletal disorders worldwide, and imply suffering and substantial societal costs, hence effective interventions are crucial. The aim of this study was to evaluate the cost-effectiveness of manual therapy compared with advice to stay active for working age persons with nonspecific back and/or neck pain. METHODS The two interventions were: a maximum of 6 manual therapy sessions within 6 weeks, including spinal manipulation/mobilization, massage and stretching, performed by a naprapath (index group), respectively information from a physician on the importance to stay active and on how to cope with pain, according to evidence-based advice, at 2 occasions within 3 weeks (control group). A cost-effectiveness analysis with a societal perspective was performed alongside a randomized controlled trial including 409 persons followed for one year, in 2005. The outcomes were health-related Quality of Life (QoL) encoded from the SF-36 and pain intensity. Direct and indirect costs were calculated based on intervention and medication costs and sickness absence data. An incremental cost per health related QoL was calculated, and sensitivity analyses were performed. RESULTS The difference in QoL gains was 0.007 (95% CI - 0.010 to 0.023) and the mean improvement in pain intensity was 0.6 (95% CI 0.068-1.065) in favor of manual therapy after one year. Concerning the QoL outcome, the differences in mean cost per person was estimated at - 437 EUR (95% CI - 1302 to 371) and for the pain outcome the difference was - 635 EUR (95% CI - 1587 to 246) in favor of manual therapy. The results indicate that manual therapy achieves better outcomes at lower costs compared with advice to stay active. The sensitivity analyses were consistent with the main results. CONCLUSIONS Our results indicate that manual therapy for nonspecific back and/or neck pain is slightly less costly and more beneficial than advice to stay active for this sample of working age persons. Since manual therapy treatment is at least as cost-effective as evidence-based advice from a physician, it may be recommended for neck and low back pain. Further health economic studies that may confirm those findings are warranted. Trial registration Current Controlled Trials ISRCTN56954776.

Abstract
Abstract
Background
Radiomics is a novel method of extracting data from medical images that is difficult to visualise through the naked eye. This technique transforms digital images that hold information on pathology into high-dimensional-data for analysis. Radiomics has the potential to enhance laryngeal cancer care and to date, has shown promise in various other specialties.
Aim
The aim of this review is to summarise the applications of this technique to laryngeal cancer and potential future benefits.
Method
A comprehensive systematic review-informed search of the MEDLINE and EMBASE online databases was undertaken. Keywords ‘laryngeal cancer’ OR ‘larynx’ OR ‘larynx cancer’ OR ‘head and neck cancer’ were combined with ‘radiomic’ OR ‘signature’ OR ‘machine learning’ OR ‘artificial intelligence’. Additional articles were obtained from bibliographies using the ‘snowball method’.
Results
Seventeen articles were identified that evaluated the role of radiomics in laryngeal cancer. Two studies affirmed the value of radiomics in improving the accuracy of staging, whilst fifteen studies highlighted the potential prognostic value of radiomics in laryngeal cancer. Twelve (of thirteen) studies incorporated an array of different head and neck cancers in the analysis and only one study assessed laryngeal cancer exclusively.
Conclusions
Literature to date has various limitations including, small and heterogeneous cohorts incorporating patients with head and neck cancers of distinct anatomical subsites and stages. The lack of uniform data on solely laryngeal cancer and radiomics means drawing conclusions is difficult, although these studies have affirmed its value. Further large prospective studies exclusively in laryngeal cancer are required to unlock its true potential.

Abstract
Background The Suboptimal Health Status Questionnaire-25 (SHS-Q-25) developed to measure Suboptimal Health Status has been used worldwide, but its construct validity has only been tested in the Chinese population. Applying Structural Equation Modelling, we investigate aspects of the construct validity of the SHS-Q-25 to determine the interactions between SHS subscales in a Ghanaian population.
Methods The study involved healthy Ghanaian participants (n = 263; aged 20–80 years; 63% female), who responded to the SHSQ-25. In an exploratory factor and parallel analysis, the study extracted a new domain structure and compared to the established five-domain structure of SHSQ-25. A confirmatory factor analysis (CFA) was conducted and the fit of the model further discussed. Invariance analysis was carried out to establish the consistency of the instrument across multi-groups.

The fit indices for the three-domain model were statistically superior to the five-domain model. There were, however, issues of insufficient discriminant validity as some average variance extracts were smaller than the corresponding maximum shared variance. The three-domain model was invariant for all constrained aspects of the structural model across age, which is an important risk factor for most chronic diseases.
Conclusion The validity tests suggest that the SHS-Q25 can measure SHS in a Ghanaian population. It can be recommended as a screening tool to early detect chronic diseases especially in developing countries where access to facilities is diminished.

Abstract
AbstractThe purpose of this review was to investigate the association between publication performance and the organizational and psychosocial work environment of academics in a university setting. In 2018 we conducted database searches in Web of Science, Medline and other key journals (hand-searched) from 1990 to 2017 based on population, exposure and outcome framework. We examined reference lists, and after a title and abstract scan and full-text reading we identified studies that were original research and fulfilled our inclusion criteria. Articles were evaluated as having a low, moderate or high risk of bias using a quality assessment form. From the studies (n = 32) identified and synthesized, work-environment characteristics could explain the quality and quantity aspects of publication performance of academics. Management practices, leadership and psychosocial characteristics are influential factors that affect academics’ publication productivity. Most of the reviewed studies were judged to be of moderate quality because of issues of bias, related to the measuring of publication outcome. The findings in the studies reviewed suggest that highly productive research academics and departments significantly tend to be influenced by the organizational and psychosocial characteristics of their working environment. The practical relevance of this review is that it highlights where academics’ performance needs support and how the work environment can be improved to bolster publication productivity.

Abstract
The paper describes the study design, research questions and methods of a large, international intervention project aimed at improving employee mental health and well-being in SMEs and public organisations. The study is innovative in multiple ways. First, it goes beyond the current debate on whether individual- or organisational-level interventions are most effective in improving employee health and well-being and tests the cumulative effects of multilevel interventions, that is, interventions addressing individual, group, leader and organisational levels. Second, it tailors its interventions to address the aftermaths of the Covid-19 pandemic and develop suitable multilevel interventions for dealing with new ways of working. Third, it uses realist evaluation to explore and identify the working ingredients of and the conditions required for each level of intervention, and their outcomes. Finally, an economic evaluation will assess both the cost-effectiveness analysis and the affordability of the interventions from the employer perspective. The study integrates the training transfer and the organisational process evaluation literature to develop toolkits helping end-users to promote mental health and well-being in the workplace.

Results: The extracted domains were reliable with Cronbach’s of 0.861, 0.821 and 0.853 respectively, for fatigue, immune-cardiovascular and cognitive, confirming the construct validity of the SHSQ-25 instrument. The CFA revealed that the model fit indices were excellent but the fit indices for the three-domain model were statistically superior to the five-domain model. There were, however, issues of insufficient discriminant validity as some average variance extracts (AVE) were smaller than the corresponding maximum shared variance (MSV). The three-domain model was invariant for all constrained aspects of the structural model across age, which is an important risk factor for most chronic diseases. Conclusion: The validity tests provide evidence to endorse the credibility of the tool and suggest that the SHS-Q25 can measure SHS in a Ghanaian population. It can be recommended as a screening tool to early detect possible for chronic diseases especially in developing countries where the access to facilities is diminished.

Abstract
Background: The Suboptimal Health Status Questionnaire-25 (SHS-Q-25) developed to measure suboptimal health status has been used worldwide, but its construct validity has only been tested in the Chinese population. In this article, we investigate aspects of the construct validity of the SHS-Q-25 to determine the interactions between SHS subscales in a Ghanaian population.Methods: The study involved healthy Ghanaian participants (n = 263; aged 20-80 years; 63% female), who responded to the SHSQ-25. In an exploratory factor and parallel analysis, the study extracted a new domain structure and compared to the established five-domain structure of SHSQ-25. A confirmatory factor analysis (CFA) was conducted and the fit of the model further discussed. Invariance analysis was carried out to establish the consistency of the instrument across multi-groups. Results: The extracted domains were reliable with Cronbach’s B of 0.861, 0.821 and 0.853 respectively, for fatigue, immune-cardiovascular and cognitive, confirming the construct validity of the SHSQ-25 instrument.

Abstract
Presenteeism, attending work while ill, has been examined in different contexts in the last few decades. The aim was to examine whether poor psychosocial working conditions and perceived work ability are associated with increased odds ratios for presenteeism, focusing on nursing professionals and care assistants. A cross-sectional population-based study was conducted. The selected individuals were extracted from representative samples of employees, aged 16–64, who participated in the Swedish Work Environment Surveys between 2001 and 2013 (n = 45,098). Three dimensions of psychosocial working conditions were measured: job demands, job control, and job support. Presenteeism and perceived work ability was measured. Using multiple logistic regression analyses, odds ratios for presenteeism with 95% confidence intervals (CI) were estimated. While nurses (n = 1716) showed the same presenteeism level as all the other occupation groups (n = 37,125), it was more common among care assistants (n = 6257). The odds ratio for presenteeism among those with high job demands (OR = 2.37, 95% CI 2.21–2.53), were higher among women than among men. For nursing professionals and care assistants, the odds ratios for presenteeism were highest among those with the lowest work ability level. The problems of presenteeism and low work ability among many health and care workers may be lessened by a reduction in psychosocial demands.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of deep tissue massage ('massage'), strengthening and stretching exercises ('exercises') or a combination of both ('combined therapy') in comparison with advice to stay active ('advice') for subacute and persistent neck pain, from a societal perspective. METHODS We conducted a cost-effectiveness analysis alongside a four-arm randomized controlled trial of 619 participants followed-up for one year. Health-related quality of life was measured using EQ-5D-3L and costs were calculated from baseline to one year. The interventions were ranked according to quality adjusted life years (QALYs) in a cost-consequence analysis. Thereafter, an incremental cost per QALY was calculated. RESULTS In the cost-consequence analysis, in comparison with advice, exercises resulted in higher QALY gains, and massage and the combined therapy were more costly and less beneficial. Exercises may be a cost-effective treatment compared with advice to stay active if society is willing to pay 17 640 EUR per QALY. However, differences in QALY gains were minimal; on average, participants in the massage group, spent a year in a state of health valued at 0.88, exercises: 0.89, combined therapy: 0.88 and, advice: 0.88. CONCLUSIONS Exercises are cost-effective compared to advice given that the societal willingness to pay is above 17 640 EUR per year in full health gained. Massage and a combined therapy are not cost-effective. While exercise appeared to have the best cost/benefit profile, even this treatment had only a modest benefit and treatment innovation is needed. Advice to stay active remains as a good therapeutic alternative from an economical perspective.

Abstract
BACKGROUND Healthy lifestyles play an important role in the prevention of premature death, chronic diseases, productivity loss and other social and economic concerns. However, workplace interventions to address issues of fitness and nutrition which include work-related outcomes are complex and thus challenging to implement and appropriately measure the effectiveness of. This systematic review investigated the impact of workplace nutrition and physical activity interventions, which include components aimed at workplace's physical environment and organizational structure, on employees' productivity, work performance and workability. METHODS A systematic review that included randomized controlled trials and or non-randomized controlled studies was conducted. Medline, EMBASE.com, Cochrane Library and Scopus were searched until September 2016. Productivity, absenteeism, presenteeism, work performance and workability were the primary outcomes of our interest, while sedentary behavior and changes in other health-related behaviors were considered as secondary outcomes. Two reviewers independently screened abstracts and full-texts for study eligibility, extracted the data and performed a quality assessment using the Cochrane Collaboration Risk-of-Bias Tool for randomized trials and the Risk-of-Bias in non-randomized studies of interventions. Findings were narratively synthesized. RESULTS Thirty-nine randomized control trials and non-randomized controlled studies were included. Nearly 28% of the included studies were of high quality, while 56% were of medium quality. The studies covered a broad range of multi-level and environmental-level interventions. Fourteen workplace nutrition and physical activity intervention studies yielded statistically significant changes on absenteeism (n = 7), work performance (n = 2), workability (n = 3), productivity (n = 1) and on both workability and productivity (n = 1). Two studies showed effects on absenteeism only between subgroups. CONCLUSIONS The scientific evidence shows that it is possible to influence work-related outcomes, especially absenteeism, positively through health promotion efforts that include components aimed at the workplace's physical work environment and organizational structure. In order to draw further conclusions regarding work-related outcomes in controlled high-quality studies, long-term follow-up using objective outcomes and/or quality assured questionnaires are required.

Abstract
Objectives The aim of the present study was to examine how presenteeism affects the risk of future disability pension among nursing professionals and care assistants (assistant nurses, hospital ward assistants, home‐based personal care workers, and child care assistants). A specific objective was to compare health and social care employees with all other occupations. Methods The study was based on a representative sample of working women and men (n = 43 682) aged 16‐64 years, who had been interviewed between 2001 and 2013 for the Swedish Work Environment Survey conducted every second year since 1989. Information on disability pension was obtained from the Social Insurance Agency's database (2002‐2014). The studied predictors were related to disability pension using Cox's proportional hazard regression with hazard ratios (HR) and 95% confidence interval (CI) and selected confounders were controlled for. The follow‐up period was 6.7 years (SD 4.2). Results Health and social care employees with frequent presenteeism showed a particularly elevated risk of future disability pension after adjusting for sex, sociodemographic variables, physical and psychosocial working conditions, and self‐rated health symptoms. In the amalgamated occupational group of nursing professionals and care assistants, the impact on disability pension of having engaged in presenteeism four times or more during the prior year remained significant (HR = 3.72, 95% CI = 2.43‐5.68). Conclusions The study suggests that frequent presenteeism contributes to an increased risk of disability pension among nursing professionals and care assistants as well as among all other occupations.

Abstract
The concurrence of wandering spleen, organoaxial gastric volvulus, and pancreatic volvulus is very rare. They have been associated with symptoms such as severe abdominal pain, abdominal distention, and vomiting. However, the diagnosis remains complicated and any delay can result in ischemia and necrosis of the organs involved. In this case presentation, we present a unique case involving a 14-year-old girl who presented initially with acute abdominal pain. Assessment with enhanced computed tomography scan led to the diagnosis of wandering spleen, organoaxial gastric volvulus, and pancreatic volvulus, in addition to cholestasis, making it the first study to report on the simultaneous occurrence of this triad and cholestasis.

Abstract
Background Exercise is effective in improving non-specific low back pain (LBP). Certain components of physical exercise, such as the type, intensity and frequency of exercise, are likely to influence participation among working adults with non-specific LBP, but the value and relative importance of these components remain unknown. The study’s aim was to examine such specific components and their influence on individual preferences for exercise for secondary prevention of non-specific LBP among working adults. Methods In a discrete choice experiment, working individuals with non-specific LBP answered a web-based questionnaire. Each respondent was given ten pairs of hypothetical exercise programs and asked to choose one option from each pair. The choices comprised six attributes of exercise (i.e., type of training, design, intensity, frequency, proximity and incentives), each with either three or four levels. A conditional logit regression that reflected the random utility model was used to analyze the responses. Results The final study population consisted of 112 participants. The participants’ preferred exercise option was aerobic (i.e., cardiovascular) rather than strength training, group exercise with trainer supervision, rather than individual or unsupervised exercise. They also preferred high intensity exercise performed at least once or twice per week. The most popular types of incentive were exercise during working hours and a wellness allowance rather than coupons for sports goods. The results show that the relative value of some attribute levels differed between young adults (age ≤ 44 years) and older adults (age ≥ 45 years) in terms of the level of trainer supervision required, exercise intensity, travel time to exercise location and financial incentives. For active study participants, exercise frequency (i.e., twice per week, 1.15; CI: 0.25; 2.06) influenced choice of exercise. For individuals with more than one child, travel time (i.e., 20 minutes, -0.55; CI: 0.65; 3.26) was also an influential attribute for choice of exercise, showing that people with children at home preferred to exercise close to home. Conclusions This study adds to our knowledge about what types of exercise working adults with back pain are most likely to participate in. The exercise should be a cardiovascular type of training carried out in a group with trainer supervision. It should also be of high intensity and preferably performed twice per week during working hours. Coupons for sports goods do not appear to motivate physical activity among workers with LBP. The findings of the study could have a substantial impact on the planning and development of exercise provision and promotion strategies to improve non-specific LBP. Providers and employers may be able to improve participation in exercise programs for adults with non-specific LBP by focusing on the exercise components which are the most attractive. This in turn would improve satisfaction and adherence to exercise interventions aimed at preventing recurrent non-specific LBP.

Abstract
OBJECTIVES The aim of this study was to propose wage multipliers that can be used to estimate the costs of productivity loss for employers in economic evaluations, using detailed information from managers. METHODS Data were collected in a survey panel of 758 managers from different sectors of the labor market. Based on assumed scenarios of a period of absenteeism due to sickness, presenteeism and work environment-related problem episodes, and specified job characteristics (i.e., explanatory variables), managers assessed their impact on group productivity and cost (i.e., the dependent variable). In an ordered probit model, the extent of productivity loss resulting from job characteristics is predicted. The predicted values are used to derive wage multipliers based on the cost of productivity estimates provided by the managers. RESULTS The results indicate that job characteristics (i.e., degree of time sensitivity of output, teamwork, or difficulty in replacing a worker) are linked to productivity loss as a result of health-related and work environment-related problems. The impact of impaired performance on productivity differs among various occupations. The mean wage multiplier is 1.97 for absenteeism, 1.70 for acute presenteeism, 1.54 for chronic presenteeism, and 1.72 for problems related to the work environment. This implies that the costs of health-related and work environment-related problems to organizations can exceed the worker's wage. CONCLUSIONS The use of wage multipliers is recommended for calculating the cost of health-related and work environment-related productivity loss to properly account for actual costs.

Abstract
The efficacy of physical exercise for the prevention and treatment of non-specific low back pain (LBP) is well documented, but little is known about how individuals value specific components of physical exercise, such as the type and design or the intensity and frequency of exercise. Other factors that influence individual differences in health choices and adherence are associated with individuals’ attitudes toward and likelihood of performing recommended exercise regimens. Current evidence shows that efficacy is similar among exercise interventions, but their features vary widely. Thus it may be difficult for clinicians to discriminate between available options in clinical practice. Considering the many challenges in determining the form of exercise best suited to the individual patient, this commentary discusses some of the practical methods that could be used to elicit individual preference for recommended health care interventions. Such methods have the advantage of providing more information for health care decision making, particularly with regard to exercise interventions for LBP. This commentary also advocates for the use of patient preference in health care decisions.

Abstract
BACKGROUND Besides causing ill health, a poor work environment may contribute to production loss. Production loss assessment instruments emphasize health-related consequences but there is no instrument to measure reduced work performance related to the work environment. AIMS To examine convergent validity and test-retest reliability of health-related production loss (HRPL) and work environment-related production loss (WRPL) against a valid comparable instrument, the Health and Work Performance Questionnaire (HPQ). METHODS Cross-sectional study of employees, not on sick leave, who were asked to self-rate their work performance and production losses. Using the Pearson correlation and Bland and Altman's Test of Agreement, convergent validity was examined. Subgroup analyses were performed for employees recording problem-specific reduced work performance. Consistency of pairs of HRPL and WRPL for samples responding to both assessments was expressed using Intraclass Correlation Coefficient (ICC) and tests of repeatability. RESULTS A total of 88 employees participated and 44 responded to both assessments. Test of agreement between measurements estimates a mean difference of 0.34 for HRPL and -0.03 for WRPL compared with work performance. This indicates that the production loss questions are valid and moderately associated with work performance for the total sample and subgroups. ICC for paired HRPL assessments was 0.90 and 0.91 for WRPL, i.e. the test-retest reliability was good and suggests stability in the instrument. CONCLUSIONS HRPL and WRPL can be used to measure production loss due to health-related and work environment-related problems. These results may have implications for advancing methods of assessing production loss, which represents an important cost to employers.

Abstract
BACKGROUND Malnutrition is a prevalent public health concern in Ghana. While studies have identified factors that influence child malnutrition and related inequalities in Ghana, very little efforts have been made to decompose these inequalities across various household characteristics. This study examined the influence of socioeconomic factors on inequality in child malnutrition using a decomposition approach. METHODS The study employed cross section data from the 2011 Multiple Indicator Cluster Survey (MICS). Analysis was done at three levels: First, concentration curves were constructed to explore the nature of inequality in child malnutrition. Secondly, concentration indices were computed to quantify the magnitude of inequality. Thirdly, decomposition analysis was conducted to determine the role of mother's education and health insurance coverage in inequality of child malnutrition. RESULTS The concentration curves showed that there exists a pro-poor inequality in child malnutrition measured by stunting and wasting. The concentration indices of these measures indicated that the magnitude of inequality was higher and significant at 1 % for weight-for-age (WAZ) (-0.1641), relative to height-for-age (HAZ) (-0.1613). The decomposition analyses show that whilst mother's education contributed about 13 and 11 % to inequality in HAZ, it contributed about 18.9 and 11.8 % to inequality in WAZ for primary and secondary or above education attainments, respectively. Finally, health insurance contributed about 1.91 and 1.03 % to inequality in HAZ and WAZ, respectively. CONCLUSION The results suggest that there is the need to encourage critical policies directed towards improving female literacy in the country. The existence of a functional health insurance system and increasing universal coverage are recommended to mitigate child malnutrition.

Abstract
Background The aim of this study is to evaluate the construct validity and responsiveness of a Swedish measure of health-related production loss as well as to investigate if there is a difference in the level of production loss within a population suffering from persistent back/neck pain and CMDs. Methods The sample was drawn from a study that assessed employees’ health and working capacity in 74 health care units before and after intervention. The study included 692 patients who reported working the previous six months at baseline measurement, and who were also asked to answer questions related to health-related production loss. Health-related measures were general health derived from Short Form-12, health-related quality of life derived from EQ-5D, and work ability derived from the Work Ability Index (WAI). Convergent validity and external responsiveness were assessed using Spearman’s Rank Correlation Coefficient and a linear regression model, respectively. Results The different measures of health showed a moderate-to-strong correlation with the measure of health-related production loss and fulfilled the criteria for construct validity. Changes in health and work ability led to significant changes in health-related production loss, which demonstrates external responsiveness. This result is valid for both the total population and for the two different subgroups that were evaluated. Conclusions The present study shows that this measure of health-related production loss is a valid measure for capturing production loss due to illness, and that work ability is more strongly correlated with health-related production loss than people’s general health is. The result shows an average of about 50 % reduced production due to illness, with back pain being the most costly.

Abstract
RNA-binding proteins (RBPs) bind to and post-transcriptionally regulate the stability of mRNAs. La-related protein 1 (LARP1) is a conserved RBP that interacts with poly-A-binding protein and is known to regulate 5'-terminal oligopyrimidine tract (TOP) mRNA translation. Here, we show that LARP1 is complexed to 3000 mRNAs enriched for cancer pathways. A prominent member of the LARP1 interactome is mTOR whose mRNA transcript is stabilized by LARP1. At a functional level, we show that LARP1 promotes cell migration, invasion, anchorage-independent growth and in vivo tumorigenesis. Furthermore, we show that LARP1 expression is elevated in epithelial cancers such as cervical and non-small cell lung cancers, where its expression correlates with disease progression and adverse prognosis, respectively. We therefore conclude that, through the post-transcriptional regulation of genes such as mTOR within cancer pathways, LARP1 contributes to cancer progression.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of medical yoga as an early intervention compared with evidence-based exercise therapy and self-care advice for non-specific low back pain. DESIGN Randomized controlled trial with a cost-effectiveness analysis. SUBJECTS A total of 159 participants randomized into the medical yoga group (n = 52), the exercise therapy group (n = 52) and the self-care advice group (n = 55). METHODS The health outcome measure EQ-5D was applied to measure quality of life data combined with cost data collected from treatment groups from baseline to 12 months follow-up. Outcome measure was health-related quality of life (HRQL). Incremental cost per quality adjusted life year (QALY) was also calculated. Cost-effectiveness analysis was conducted primarily from the societal and employer perspectives. RESULTS Medical yoga is cost-effective compared with self-care advice if an employer considers the significant improvement in the HRQL of an employee with low back pain justifies the additional cost of treatment (i.e. in this study EUR 150). From a societal perspective, medical yoga is a cost-effective treatment compared with exercise therapy and self-care advice if an additional QALY is worth EUR 11,500. Sensitivity analysis suggests that medical yoga is more cost-effective than its alternatives. CONCLUSION Six weeks of uninterrupted medical yoga thera-py is a cost-effective early intervention for non-specific low back pain, when treatment recommendations are adhered to.

Abstract
This paper examines the influence of the national health insurance scheme on elderly demand for family-based care and support. It contributes to the growing concern on the rapid increase in the elderly population globally using micro-level social theory to examine the influence the health insurance has on elderly demand for family support. A qualitative case study approach is applied to construct a comprehensive and thick description of how the national health insurance scheme influences the elderly in their demand for family support. Through focused interviews and direct observation of six selected cases, in-depth information on primary carers, living arrangement and the interaction between the health insurance as structure and elders as agents are analyzed. The study highlights that the interaction between the elderly and the national health insurance scheme has produced a new stratum of relationship between the elderly and their primary carers. Consequently, this has created equilibrium between the elderly demand for support and support made available by their primary carers. As the demand of the elderly for support is declining, supply of support by family members for the elderly is also on the decline.

Abstract
This paper examines how organization and financing of maternal health services influence health-seeking behavior in Bosomtwe district, Ghana. It contributes in furthering the discussions on maternal health-seeking behavior and health outcomes from a health system perspective in sub-Saharan Africa. From a health system standpoint, the paper first presents the resources, organization and financing of maternal health service in Ghana, and later uses case study examples to explain how Ghana's health system has shaped maternal health-seeking behavior of women in the district. The paper employs a qualitative case study technique to build a complex and holistic picture, and report detailed views of the women in their natural setting. A purposeful sampling technique is applied to select 16 women in the district for this study. Through face-to-face interviews and group discussions with the selected women, comprehensive and in-depth information on health- seeking behavior and health outcomes are elicited for the analysis. The study highlights that characteristics embedded in decentralization and provision of free maternal health care influence health-seeking behavior. Particularly, the use of antenatal care has increased after the delivery exemption policy in Ghana. Interestingly, the study also reveals certain social structures, which influence women's attitude towards their decisions and choices of health facilities.

Abstract
Abstract
Background: Pre-clinical models used by our group have demonstrated that thymidylate synthase (TS) inhibition leads to redistribution of the nucleoside transporter, ENT1, to the cell membrane and hence increases the tissue uptake of [18F]fluorothymidine (FLT).Methods: In this study we assessed, for the first time, the altered pharmacokinetics of FLT in patients following TS inhibition. We analyzed 10 lesions from 6 breast cancer patients by positron emission tomography (PET) before and after treatment with capecitabine.Results: Whereas drug treatment did not alter tumor delivery pharmacokinetic variables or blood flow, tumor FLT retention variables increased with drug treatment in all but one patient. The baseline average standardized uptake value (SUV) at 60 min, rate constant for the net irreversible transfer of radiotracer from plasma to tumor (Ki) and unit impulse response function (IRF) at 60 min were 11.11 x 10-5 m2/ml, 4.38 x 10-2 ml plasma/min/ml tissue and 4.93 x 10-2 /min, respectively. At 1 h after capecitabine, the SUV was 13.55 x 10-5 m2/ml (p=0.004), Ki 7.40 x 10-2 ml plasma/min/ml tissue (p=0.004) and IRF 7.40 x 10-2 /min (p= 0.002).Conclusion: FLT pharmacokinetics did not change in normal tissues suggesting that the effect was largely restricted to tumor (p=0.55). In summary, we have identified FLT-PET retention parameters that could be used in future early clinical studies to measure the pharmacodynamics of TS inhibitors, as well as for identifying patients who are unlikely to benefit from TS inhibition.

Abstract
1110 Background: Molecular imaging techniques are increasingly being used in cancer diagnosis, staging, and assessment of response to treatment. This study sought to evaluate, for the first time, [11C]choline-PET in patients with breast cancer. The potential of [11C]choline-PET for differentiating tumours from normal tissue, correlation with molecular markers, determine its normal variability range, and finally the effect of trastuzumab on [11C]choline uptake in patients with breast cancer was investigated. Methods: 21 patients with newly diagnosed and recurrent breast cancer AJCC stage II-IV were enrolled in the study, all of whom had a baseline dynamic [11C]choline-PET scan with arterial sampling. 14 patients had 2 [11C]choline-PET scans to examine reproducibility, and 7 had a scan after trastuzumab. Analysis of [11C]choline uptake was measured using SUV, Ki (irreversible retention), and IRF@60min (retention using spectral analysis). Results: Breast tumour lesions were visualised by [11C]choline PET in all patients. The difference in tumour and non-tumour uptake were significant for SUV, Ki, and IRF@60 min (Wilcoxon p < 0.0001 for all parameters). [11C]choline uptake was reproducible in breast tumour lesions (r2 = 0.945 for SUV, 0.894 for Ki, and 0.799 for IRF60). The metabolism analysis of arterial plasma samples in 19 patients showed that [11C]choline decreased rapidly post-injection such that at 60 mins the mean radioactivity in arterial plasma due to choline was 15.15 ± 2.16%.Early responses to trastuzumab were determined to be significant in 5 lesions which corresponded with 3 clinical responses. Conclusions: [11C]choline-PET is a promising imaging modality in breast cancer, and could play an important role for determining response to novel treatment strategies in vivo.

Abstract
14067 Background: In vivo imaging of avβ3 expression in tumors and tumor endothelial cells may be a useful biomarker of angiogenesis. [18F]AH11585 is a novel peptide containing an Arginine-Glycine-Aspartic Acid (RGD) motif that binds to avβ3 with high affinity designed for use in PET studies. Methods: 7 patients with metastatic breast cancer (aged 37–68 years) received intravenous injections of [18F]AH11585 and were scanned dynamically by PET over 61.5 mins. Radioactivity concentrations, derived from regions of interest placed on tumour and normal tissues, were analysed mathematically to determine the net irreversible uptake (Ki), fractional retention (FRT) and standardized uptake at 56.5min (SUV) of the radiotracer. Computed tomography (CT) was performed within 4 weeks of the scan. Results: Tumor lesions were clearly visible on PET images in 6/7 patients. In one patient with a palpable supraclavicular lymph node not visible on CT, we were unsure if a hyperintense region visible by PET was tumor. In total 18/19 tumor lesions were identified on both PET and corresponding CT images. Tumors in areas of low background were hyperintense (lung, bone, breast) whereas those in areas of high background were hypointense regions (liver). Tumors with central necrosis showed high uptake of [18F]AH11585 around the periphery only. Mathematical analysis demonstrated irreversible retention of [18F]AH11585 in tumors. [18F]AH11585-PET discriminated between non-liver lesions (n=10) and normal tissues: Ki (p=0.002), FRT (p=0.0039), SUV (p=0.002). Corresponding comparisons for liver lesions (n=8) were significant for FRT (p=0.0078) and SUV (p=0.0078) only. Conclusions: [18F]AH11585 PET is a promisng method for in vivo imaging of avβ3 integrin expression in metastatic breast cancer. No significant financial relationships to disclose.

Abstract
613 Background: [11C]Choline is a novel PET radiotracer. Preclinical studies suggest that it may be promising in breast cancer. [11C]Choline has been recently evaluated as a screening agent in prostate cancer, but no studies have yet investigated its potential in breast cancer. We report a pilot study evaluating the utility and reproducibility of [11C]Choline-PET in breast cancer. Methods: Dynamic imaging was performed on an ECAT962 HR+ PET scanner for 65 min after intravenous injection with 190–369 MBq [11C]choline. Patients with locally advanced and metastatic breast cancer were eligible. All histological subtypes were included (ductal, lobular, and inflammatory). Arterial blood samples were taken continuously for 10 min, with 8 discrete samples up to 60 min to measure [11C]choline and metabolites. Tissue uptake was determined by standardised uptake value at 60 min (SUV, dose and BSA corrected) and Ki (irreversible trapping) calculated using Patlak (corrected for [11C]choline metabolites in plasma) and modified Patlak analysis (corrected for plasma + tissue metabolites). Reproduciblilty scans were performed 2–17 days later in the absence of treatment. Results: Tumour [11C]choline uptake was observed in 10 out of 11 patients (12 out of 13 distinct lesions). There was a significant difference between tumour and normal tissue (breast/lung) in [11C]choline uptake for Ki (p<0.0001) and SUV (p<0.0001). Tissue uptake was of the order lung ≤ normal breast < tumour < liver ≤ spleen. [11C]choline was rapidly metabolised, at 60 min the mean ± S.E. plasma radioactivity due to [11C]choline was 16.4 ± 2.9%. [11C]Choline uptake was found to be reproducible for Ki (modified Patlak: r=0.93, p<0.0001, Patlak: r=0.85, p=0.002) and SUV (r=0.94, p<0.0001) - measured in 8 patients (median of 2 days after the 1st scan). Tumour Patlak Ki was 13.2% > Ki calculated using modified Patlak analysis. Conclusions: [11C]Choline-PET imaging of breast cancer is promising and warrants further evaluation. Tumour [11C]Choline uptake measured by Ki and SUV is reproducible. We plan to study the relationship between choline uptake measured by PET and immunoassays of tumour samples. Functional imaging could have a vital role to determine the efficacy of target-specific agents. No significant financial relationships to disclose.

Abstract
Estrogen receptor alpha (ERalpha) is a ligand-inducible transcription factor that acts to regulate gene expression by binding to palindromic DNA sequence, known as the estrogen response element, in promoters of estrogen-regulated genes. In breast cancer ERalpha plays a central role, where estrogen-regulated gene expression leads to tumor initiation, growth and survival. As an approach to silencing estrogen-regulated genes, we have studied the activities of a fusion protein between ERalpha and the promyelocytic leukemia zinc-finger (PLZF) protein, a transcriptional repressor that acts through chromatin remodeling. To do this, we have developed lines from the estrogen-responsive MCF-7 breast cancer cell line in which the expression of the fusion protein PLZF-ERalpha is conditionally regulated by tetracycline and shows that these feature long-term silencing of the expression of several well-characterized estrogen-regulated genes, namely pS2, cathepsin-D and the progesterone receptor. However, the estrogen-regulated growth of these cells is not inhibited unless PLZF-ERalpha expression is induced, an observation that we have confirmed both in vitro and in vivo. Taken together, these results show that PLZF-ERalpha is a potent repressor of estrogen-regulated gene expression and could be useful in distinguishing estrogen-regulated genes required for the growth of breast cancer cells.

Abstract
One of the most lethal aspects of cancer arises from its ability to invade and metastasize. Determining the factors that promote cancer cell invasion and metastasis is therefore critically important in treating this disease. The tumour physiological environment is uniquely different from normal tissue, and exhibits hypoxia, acidic extracellular pH and high levels of lactate. This environment, dictated largely by abnormal tumour vasculature and metabolism, in turn also promotes angiogenesis. The physiological environment, tumour metabolism, angiogenesis and vascularization are therefore inextricably linked. We have developed and applied non-invasive magnetic resonance (MR) imaging (I) and spectroscopy (S) techniques to understand the role of vascular, physiological and metabolic properties in cancer invasion and metastasis. These MR studies are performed with human breast and prostate cancer cells maintained in culture or grown as solid tumours in immune-suppressed mice. We have detected significant differences in vascular, physiological and metabolic characteristics of metastatic and non-metastatic human breast and prostate cancer models with MRI and MRS. Using a combined MRI/MRS approach we are currently acquiring metabolic, extracellular pH and vascular images from the same localized regions within a solid tumour to further understand the dynamics between these parameters and their role in cancer invasion and metastasis.

Abstract
Positron Emission Tomography (PET) has the potential to improve efficacy of established and novel cancer therapies and to assist more rapid and rational progression of promising novel therapies into the clinic. This is due to PET's unrivalled sensitivity and ability to monitor the pharmacokinetics and pharmacodynamics of drugs and biochemicals radiolabelled with short -lived positron emitting radioisotopes. PET is a multidisciplinary science which employs chemists, biologists, mathematical modellers, pharmacologists as well as clinicians. Clinical research questions in oncology determine the methodological challenges faced by these other disciplines. Within this context we focus on the developments of the radiolabelled compounds that have underpinned the clinical work in oncology for monitoring tumour and normal tissue pharmacokinetics, assessment of tumour response, cell proliferation, gene expression, hypoxia, multidrug resistance and status of receptors on tumours.
