Generalised Estimating Equations

Low back pain (LBP) patients undergoing lumbar spine decompression surgery (LSDS) often suffer from multi-comorbidity and experience high work disability. This study aimed to identify diagnosis-specific work disability patterns in all LBP-patients before and after LSDS during 2008–2010, that were aged 19–60 years and living in Sweden (n = 10,800) and compare these patterns to LBP-patients without LSDS (n = 109,179), and to matched individuals without LBP (n = 472,191). Work disability days (long-term sickness absence (LTSA), disability pension (DP)) during the three years before to three years after the cohort’s entry date were identified by generalised estimating equations. LBP-patients undergoing LSDS had higher overall work disability during the three years following surgery (LTSA: 23.6%, DP: 6.3%) than LBP-patients without LSDS (LTSA: 19.5%, DP: 5.9%), and those without LBP (LTSA: 7.9%, DP: 1.7%). Among patients undergoing LSDS, the prevalence of work disability due to dorsopathies increased from 20 days three years before surgery to 70 days in the year after and attenuated to 30 days in the third year following surgery. Work disability for other diagnoses remained stable at a low level in this group (<10 days annually). LBP-patients undergoing LSDS have an unfavourable long-term work disability prognosis, primarily due to dorsopathies. Decompression surgery seemed to restrict further inclines in work disability in the long run.

Aims: Scientific knowledge about risk factors for work disability in terms of long-term sickness absence and disability pension following lumbar spine decompression surgery remains insufficient. This study aimed to investigate the associations between socio-demographic, work-related, and medical characteristics with subsequent long-term sickness absence (>90 days) and disability pension for individuals who underwent lumbar spine decompression surgery. Methods: A prospective cohort study of all individuals aged 19–60 years with diagnosed dorsopathies, who underwent lumbar spine decompression surgery 2008–10 in Sweden ( n=7373) was performed. Univariate and multivariate hazard ratios with 95% confidence intervals regarding long-term sickness absence and disability pension with a 3-year follow-up period were estimated by Cox proportional regression. Results: Low educational level, being a non-European immigrant and preoperative sickness absence were risk factors for both long-term sickness absence and disability pension (hazard ratios: 1.2–3.8). Female sex was a risk factor for long-term sickness absence (hazard ratios: 1.3) whereas age >44 years and being a Nordic immigrant were risk factors for disability pension (hazard ratios: 1.9–2.6). Medical factors as common mental disorders, other mental disorders, prescribed psychiatric medication and somatic comorbidity were risk factors for both long-term sickness absence and disability pension (hazard ratios: 1.2–3.4). A simultaneous lumbar fusion surgery and high preoperative pain severity were risk factors for long-term sickness absence (hazard ratios 1.2–1.8). Conclusions: To prevent long-term work disability after lumbar spine decompression surgery, specific focus is required on older and female patients, those with mental or somatic comorbidities, high levels of preoperative pain or sickness absence, with a simultaneous lumbar fusion surgery, a low educational level or a non-European immigrant background.

Purpose This study aims to examine the house price fluctuations in G7 countries by using the multifractal detrended fluctuation analysis (MF-DFA) for the years 1970–2019. The study examined the market efficiency between the short-term and long-term in the full sample period, before and after the global financial crisis period. Design/methodology/approach This study uses the MF-DFA to analyze house price fluctuations. Findings The findings confirmed that the housing market series are multifractal. Furthermore, all the markets showed long-term persistence in both the short and long-term. The USA is identified as the most persistent house market in the short run and Japan in the long run. Moreover, in terms of efficiency, Canada is identified as the most efficient house market in the long run and the UK in the short run. Finally, the result of before and after the financial crisis period is consistent with the full sample result. Originality/value The contribution of this study in the literature is fourfold. This is the first study that has examined the house prices efficiency by using the MF-DFA technique given by Kantelhardt et al. (2002). Previously, the house market prices and efficiency has been investigated using generalized Hurst exponent (Liu et al., 2019), Quantile Regression Approach (Chae and Bera, 2019; Tiwari et al., 2019) but no study to the best of the knowledge has been done that has used the MF-DFA technique on the housing market. Second, this is the first study that has focused on the house markets of G7 countries. Third, this study explores the house market efficiency by dividing the market into two periods i.e. before and after the financial crisis. The study strives to investigate if the financial crisis determines the change in the degree of market efficiency or not. Finally, the study gives valuable insights to the investors that will help them in their investment decisions.

Abstract Background Musculoskeletal disorders, and in particular low-back pain (LBP), are common among blue collar workers. In the work environment, both physical- and psychosocial risk factors exist. Working in warehouses in Denmark involve large quantities of occupational lifting, high work pace and a low degree of influence at work. This study investigates both acute and long-term associations between physical- and psychosocial work environmental factors and risk of LBP in warehouse workers. The specific study aims are to investigate 1) exposure-response associations between quantity of occupational lifting and short-term (day-to-day) changes in LBP, 2) the influence of accumulated workdays and rest days during a working week on LBP, 3) long-term association between occupational lifting exposure and LBP when assessed over 1 year, and 4) the role of psychological and social factors on the above associations. Methods The present study is designed as a 1-year prospective cohort study that will examine full-time warehouse workers from up to five retail chains in Denmark. Study aims 1 and 2 will be addressed using objective data based on company records with information on weight of all the goods handled by each warehouse worker during every single workday for 3 weeks. During this period, each worker will reply to text messages received before and after every workday (also on days off work) in which study participants will score their pain in the low back, bodily fatigue and perceived mental stress (scale 0–10). Long-term pain development is assessed using questionnaire surveys before and after 1 year. Further, pressure pain threshold (PPT) will be measured for selected trunk extensor muscles in approximately 50 workers using algometry along with measurements of maximal trunk extensor strength. Associations are modelled using linear mixed models with repeated measures between variables and LBP controlled for relevant confounders. Discussion This study provides knowledge about the acute and long-term associations between physical- and psychosocial work environmental factors and LBP. The obtained data will have the potential to provide recommendations on improved design of the working week to minimize the risk of LBP among warehouse workers, and may potentially enable to identify a reasonable maximum lifting threshold per day (ton lifted/day).

Objective To evaluate the responses of C-terminal telopeptide (CTX) and serum osteocalcin after the first 4 months of treatment with strontium ranelate (SR) and demonstrate their association with long-term bone density changes. Subjects and Methods A sample of 13 postmenopausal women with osteoporosis was analyzed (mean age 65 ± 7.7 years), who were treated with SR for an average of 2.56 ± 0.86 years. All patients had undergone previous treatment with bisphosphonates for an average period of 4.88 ± 2.27 years. Serum CTX and osteocalcin levels were determined before and after four months of treatment with SR. Bone mineral density in the lumbar spine and femoral neck were obtained before and after treatment with SR. Results We observed an average increase of 53.7% in the CTX levels, and 30.7% in the osteocalcin levels. The increase in bone markers was associated with a mean 4.8% increase in lumbar spine bone mineral density (BMD) from 0.820 to 0.860 g/cm2 ( T-score from –2.67 to –1.92; P= 0.001), after 2.5 years of treatment with SR. Conclusion These data suggest an anabolic effect of SR on postmenopausal women who were previously treated with long-term bisphosphonates.

Background: The chronic low back pain (LBP) had been considered an important occupational disorder with several strategy available to treatment, however, few studies had been evaluated the treatment combination. Objectives: The aim of present study was compared the effects of combination of crocheting associated to Kinesiotherapy treatment and Kinesiotherapy isolated treatment on function of lumbar spine and pain during achievement of daily life in patients with chronic LBP. Methods: Forty subjects were distributed randomly in two groups: Crochetagem + Kinesioterapy (C; n: 18; 47.5 ± 7.75 years) and Kinesiotherapy (K, n: 18; 45.3 ± 8.93 years). The C group was treated by crocheting technique associated with kinesiotherapy using therapeutic ball. The K group performed a kinesiotherapy treatment using just a therapeutic ball. The following parameters were evaluated: abdominal strength, articular range motion and the data of Rolland Morris and Oswestry Disability Index questionnaires were evaluated before and after 8 weeks of treatment. Both groups performed all therapeutic sessions for 50 minutes, three times a week. Results: Significant differences (p<0.05) were found just on time to trunk flexion and extension, right and left lateral trunk, pain and abdominal strength. However, significant differences on time (p<0.05) was found on Rolland Morris and Oswestry data questionaries parameters just on C group, additionally the values of C group were lower than K group after treatment. Conclusion: Both kinesiotherapy isolated and association of crocheting and kinesiotherapy were useful to improve functional parameters, however the data from Rolland Morris and Oswestry questionaries were lower just on crocheting associated to kinesiotherapy group indicating increment on function of lumbar spine and decrease on pain during achievement of daily life.
