Sex differences in outcomes after revascularization for acute lower limb ischemia: Propensity score adjusted analysis.

BACKGROUND: Previous reports have suggested higher rates of mortality and amputation for female patients in acute lower limb ischemia (ALI). The aims of the present study were to investigate if there is a difference in mortality, amputation, and fasciotomy between the sexes. METHODS: A retrospective cohort study of consecutive patients undergoing index revascularization for ALI between 2001 and 2018 was conducted. A propensity score was created through a logistic regression with female/male sex as an outcome. Cox regression analyses for 90-day and 1-year mortality, combining major amputation/mortality, and logistic regression for major bleeding and fasciotomy, were performed. All analyses were performed with and without adjusting for propensity score. RESULTS: A total of 709 patients were included in the study of which 45.9% were women. Mean age was 72.1 years. Females were older and had higher rates of atrial fibrillation, embolic disease, and lower estimated glomerular filtration rate, while men more often had anemia and chronic peripheral arterial disease. Mortality at 1 year was 21.2% for women and 14.7% for men. The adjusted hazard ratio for 1-year mortality was 0.99 (95% CI 0.67-1.46). Fasciotomy was performed in 7.1% of female and 12.8% of male patients; the adjusted odds ratio was 0.52 (95% CI 0.29-0.91). CONCLUSION: Sex was not found to be an independent risk factor for mortality or combined major amputation/mortality after revascularization for acute lower limb ischemia, whereas women had lower odds of undergoing fasciotomy. Whether women are underdiagnosed or do not develop acute compartment syndrome in the lower leg as often as men should be evaluated prospectively.

Scientific approach, attitudes, and perspectives on research among Swedish physiotherapy students-a cross-sectional study.

BACKGROUND: Scientific evidence is important to evidence-based practice. Hence, the application of evidence-based practice requires relevant skills and an understanding of science, which therefore need to be learned and trained during the undergraduate program in physiotherapy. The aim of this study was to investigate attitudes, perceived competence, and conditions for a scientific approach among physiotherapy students in Sweden, and to compare attitudes and perceived competence between students in different program years. METHODS: Physiotherapy students from six universities (n = 1499) were invited to respond to a digital survey. The survey contained questions regarding attitudes toward science, perceived competence in research interpretations and open comments regarding requirements for a strengthened scientific approach during education. Comparisons between education years were performed with ANOVA/Kruskal‒Wallis test (scale outcomes) and logistic regression (binary outcomes). RESULTS: A total of 466 students responded to the survey. In total, 57% (n = 266) of the students had a high interest in science. No significant difference in interest in science was found between students in the three program years, but 75% (n = 347) reported increased interest during the program. A perceived high ability to understand the structure and performance of scientific studies was reported by 31% (n = 144), to evaluate the methodology by 16% (n = 72) and to interpret statistical results from scientific studies by 12% (n = 55). The lowest perceived competence was reported among students in their second year (p < 0.05). A majority of the students (88%; n = 410) reported a perceived personal need for strengthened conditions for a scientific approach, with suggested prerequisites during education via increased theoretical and applied understanding of the research. CONCLUSION: Even though this study does not fully cover physiotherapy students at all undergraduate programmes in Sweden, the results support that a scientific approach and training should be strengthened during education to enable physiotherapists to understand and interpret science and to fully apply an evidence-based approach in upcoming clinical practice. Both theoretical and applied knowledge and understanding are needed.

Prophylactic and Therapeutic Fasciotomy for Acute Compartment Syndrome after Revascularization for Acute Lower Limb Ischemia-Renal and Wound Outcomes.

BACKGROUND: Acute Compartment Syndrome (ACS) is a significant complication after revascularization for acute lower limb ischemia (ALI). High risk patients sometimes undergo prophylactic fasciotomy (PF) to prevent ACS. Patients that develop ACS undergo therapeutic fasciotomy (TF). The optimal timing of fasciotomy has been debated. The aim of this study was to describe and compare renal and wound outcomes in patients undergoing PF and TF. METHODS: A retrospective cohort study including 76 patients undergoing PF (n = 40) or TF (n = 36) after revascularization for ALI between 2006 and 2018. Estimated glomerular filtration rate (e-GFR) was used to evaluate renal function and compare within (paired-samples t-test) and between (analysis of variance) groups. Wound complications and healing time were compiled from the complete wound healing period and compared between groups with Pearson's chi-squared-and log-rank test, respectively. RESULTS: E-GFR improved over the in-hospital period with 8.2 ml/min/1.73 m2 (95% confidence interval [CI] 2.4-14.1, P = 0.007) in the PF group and 4.4 ml/min/1.73 m2 (95% CI 1.2-7.7, P = 0.010) in the TF group, with no significant difference between the 2 groups (0.3 ml/min/1.73 m2, 95% CI -6.7 to 7.4, P = 0.93). The wound infection rate was higher after TF (PF = 60.6 % and TF = 82.4 %, P = 0.048), whereas rate of other wound complications (PF = 61.3 % and TF = 35.3%, P = 0.036) was higher after PF. CONCLUSIONS: Overall wound complications were high, whereas renal function improved during in-hospital stay. A more conservative approach to fasciotomy could avoid unnecessary fasciotomies and reduce wound complications, while holding the potential to sufficiently preserve renal function if fasciotomy is needed for ACS. This would be possible and safe if an early diagnosis and treatment of ACS can be ensured.

Short-Term Complications and Outcomes in Pharmaco-Mechanical Thrombolysis First and Catheter-Directed Thrombolysis First in Patients with Acute Lower Limb Ischemia.

BACKGROUND: Pharmaco-mechanical thrombolysis (PMT) has emerged as a treatment option in patients with acute lower limb ischemia (ALI), especially Rutherford IIb (motor deficit) for rapid revascularization, but supportive data is scarce. The aim of the present study was to compare the effects of thrombolysis, complications, and outcomes of PMT first versus catheter-directed thrombolysis (CDT) first in a large cohort of patients with ALI. METHODS: All endovascular thrombolytic/thrombectomy events in patients with ALI performed between January 1st, 2009, and December 31st, 2018 (n = 347) were included. Successful thrombolysis/thrombectomy was defined as complete or partial lysis. Reasons for using PMT were described. Complications such as major bleeding, distal embolization, and new onset of renal impairment, and major amputation and mortality at 30 days were compared between PMT (AngioJet) first and CDT first groups in a multivariable logistic regression model with adjustment for age, gender, atrial fibrillation, and Rutherford IIb. RESULTS: The most common reason for initial use of PMT was the need for rapid revascularization, and the most common reason for use of PMT after CDT was the insufficient effect of CDT. Presentation of Rutherford IIb ALI was more common in the PMT first group (36.2% vs. 22.5%, respectively, P = 0.027). Among the 58 patients receiving PMT first, 36 (62.1%) were terminated within a single session of therapy without need of CDT. The median duration of thrombolysis was shorter (P < 0.001) for the PMT first group (n = 58) compared to the CDT first group (n = 289) (4.0 hr vs. 23.0 hr, respectively). There was no significant difference in amount of tissue plasminogen activator given, successful thrombolysis/thrombectomy (86.2% and 84.8%), major bleeding (15.5% and 18.7%), distal embolization (25.9% and 16.6%), major amputation or mortality at 30-days (13.8% and 7.7%) in the PMT first compared to the CDT first group, respectively. The proportion of new onset of renal impairment was higher in the PMT first compared to the CDT first group (10.3% vs. 3.8%, respectively), and the increased odds (odds ratio 3.57, 95% confidence interval 1.22-10.41) were maintained in the adjusted model. In Rutherford IIb ALI, no difference in rate of successful thrombolysis/thrombectomy (76.2% and 73.8%), complications or 30-day outcomes was found between PMT first (n = 21) and CDT (n = 65) first group. CONCLUSIONS: PMT first appears to be a good treatment alternative to CDT in patients with ALI, including Rutherford IIb. The found renal function deterioration in the PMT first group needs to be evaluated in a prospective, preferably randomized trial.

Experiences of activity monitoring and perceptions of digital support among working individuals with hip and knee osteoarthritis - a focus group study.

BACKGROUND: Mobile health (mHealth), wearable activity trackers (WATs) and other digital solutions could support physical activity (PA) in individuals with hip and knee osteoarthritis (OA), but little is described regarding experiences and perceptions of digital support and the use of WAT to self-monitor PA. Thus, the aim of this study was to explore the experiences of using a WAT to monitor PA and the general perceptions of mHealth and digital support in OA care among individuals of working age with hip and knee OA. METHODS: We conducted a focus group study where individuals with hip and knee OA (n = 18) were recruited from the intervention group in a cluster-randomized controlled trial (C-RCT). The intervention in the C-RCT comprised of 12-weeks use of a WAT with a mobile application to monitor PA in addition to participating in a supported OA self-management program. In this study, three focus group discussions were conducted. The discussions were transcribed and qualitative content analysis with an inductive approach was applied. RESULTS: The analysis resulted in two main categories: A WAT may aid in optimization of PA, but is not a panacea with subcategories WATs facilitate PA; Increased awareness of one's limitations and WATs are not always encouraging, and the second main category was Digital support is an appreciated part of OA care with subcategories Individualized, early and continuous support; PT is essential but needs to be modernized and Easy, comprehensive, and reliable digital support. CONCLUSION: WATs may facilitate PA but also aid individuals with OA to find the optimal level of activity to avoid increased pain. Digital support in OA care was appreciated, particularly as a part of traditional care with physical visits. The participants expressed that the digital support should be easy, comprehensive, early, and continuous.

Can a workplace dialogue impact the perceived influence of neck and/or backpain on everyday activities and performance at work? A secondary analysis from the randomized controlled trial WorkUp.

BACKGROUND: Neck- and back- pain are highly prevalent conditions in Sweden and world-wide. Such pain often has consequences on everyday activities, work- and personal life. One consequence is work absence and decreased productivity at work. Adding a workplace dialogue to structured physiotherapy was recently found to lead to increased workability, i.e., not being on sick leave during the 12th month of follow up. AIM: The aim of the study was to explore the effect of a workplace dialogue intervention on secondary outcomes: perceived impact of neck and/or back pain on everyday activities and on performance at work, and total days of sick leave during 12 month follow up. A further aim was to examine associations between perceived influence of pain, and sick leave. METHOD: Patients with neck and/or back pain in primary care in the south of Sweden were randomized into structured physiotherapy alone (n = 206) or with the addition of a workplace dialogue (n = 146). Data regarding the pain's influence on everyday activities and on performance at work were collected using weekly text messages for 52 weeks. The pattern of change in perceived influence of neck and/or back pain on everyday activities and performance at work was compared between the groups with linear mixed models. Cross sectional correlations between perceived influence of neck and/or back pain on everyday activities and performance at work, and days of sick leave, during the preceding four weeks at months 3, 6, 9 and 12 were examined. RESULT: We found no differences in change of perceived influence of neck and/or back pain on daily activities or perceived performance at work, or total days of sick leave during the 12 months of follow up between the groups with structured physiotherapy with or without a workplace dialogue. There was a weak to moderate positive correlation between days of sick leave and perceived influence of neck and/or back pain on everyday activities and performance at work (rho 0.28-0.47). CONCLUSION: A workplace dialogue was not found to affect the perceived impact of neck and/or back pain on everyday activities and performance at work.

Promoting work ability with a wearable activity tracker in working age individuals with hip and/or knee osteoarthritis: a randomized controlled trial.

BACKGROUND: Physical activity (PA) may improve work ability and health in individuals with hip and/or knee osteoarthritis (OA). The use of wearable activity trackers (WATs) has been shown to increase PA and improve other health outcomes but little is known concerning their effect on work ability. The objectives of this study were to examine the effect of self-monitoring PA with a WAT on work ability, PA and work productivity among individuals of working age with hip and/or knee OA. METHODS: Individuals (n = 160) were included and cluster-randomized to a Supported Osteoarthritis Self-management Program (SOASP) with the addition of self-monitoring PA using a commercial WAT for 12 weeks (n = 86), or only the SOASP (n = 74). Primary outcome was self-reported work ability measured with the Work Ability Index (WAI) and secondary outcomes were self-reported PA measured with the International Physical Activity Questionnaire - Short Form (IPAQ-SF) and work productivity, measured with the Work Productivity and Activity Impairment scale: Osteoarthritis (WPAI:OA) at baseline and after 3, 6 and 12 months. Data was primarily analysed with linear mixed models. RESULTS: Participants with data from baseline and at least one follow-up were included in the analyses (n = 124). Linear mixed models showed no statistically significant difference between groups regarding pattern of change in work ability or PA, from baseline to follow-ups. Also, neither group had a statistically significant difference in work ability between baseline and each follow-up. CONCLUSION: The SOASP together with self-monitoring PA with a WAT did not have any effect on the primary outcome variable work ability. Participants already at baseline had good work ability and were physically active, which could have reduced the possibility for improvements. Future interventions should target a population with lower work ability and PA-level. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03354091 . Registered 15/11/2017.

Physical activity patterns, adherence to using a wearable activity tracker during a 12-week period and correlation between self-reported function and physical activity in working age individuals with hip and/or knee osteoarthritis.

BACKGROUND: A majority of individuals with osteoarthritis (OA) are insufficiently physically active. Self-monitoring with wearable activity trackers (WAT) could promote physical activity (PA), and increased knowledge of PA patterns and adherence to using a WAT is needed. The aim of this study was to describe PA patterns and adherence to WAT-use during an intervention among participants of working age with hip and/or knee OA. The study further explores the correlation between self-reported joint function and PA. METHODS: Individuals of working age with hip and/or knee OA who used a WAT, Fitbit Flex 2, for 12 weeks were included. Participants monitored their PA in the Fitbit-app. An activity goal of 7,000 steps/day was set. Steps and minutes in light (L), moderate and vigorous (MV) PA were collected from the Fitbit. Self-reported joint function (HOOS/KOOS) was completed. Data was analyzed with linear mixed models and Spearman's rank correlation. RESULTS: Seventy-five participants (45-66 years) walked on average 10 593 (SD 3431) steps/day, spent 248.5 (SD 42.2) minutes in LPA/day, 48.1 (SD 35.5) minutes in MVPA/day, 336.0 (SD 249.9) minutes in MVPA/week and used the Fitbit for an average of 88.4 % (SD 11.6) of the 12-week period. 86.7 % took > 7,000 steps/day and 77.3 % spent > 150 min in MVPA/week. Mean daily steps/week decreased significantly over the 12 weeks (ß-coefficient - 117, 95 % CI -166 to -68, p = < 0.001) as well as mean daily minutes in LPA/week (ß-coefficient - 2.3, 95 % CI -3.3 to -1.4, p = < 0.001), mean daily minutes in MVPA/week (ß-coefficient - 0.58, 95 % CI -1.01 to -0.16, p = 0.008) and mean adherence to Fitbit-use per week (ß-coefficient - 1.3, 95 % CI -1.8 to -0.8, p = < 0.001). There were no significant correlations between function (HOOS/KOOS) and PA. CONCLUSIONS: The majority of participants reached 7,000 steps/day and the recommended 150 min in MVPA per week. However, PA decreased slightly but gradually over time. Adherence to using the Fitbit was high but also decreased during the intervention. Understanding PA patterns and the use of a Fitbit to promote PA could be beneficial in tailoring interventions for individuals with hip and/or knee OA.

Psychological readiness is related to return to sport following hip arthroscopy and can be assessed by the Hip-Return to Sport after Injury scale (Hip-RSI).

PURPOSE: Psychological readiness may play an important role in the return to sport (RTS) process following hip arthroscopy (HA), but there are limited tools for the measurement of this construct. The aim of this study was to modify the Swedish version of the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale for use in HA patients and evaluate its psychometric properties. METHODS: Content validity of a modified version of the Swedish ACL-RSI (Hip-RSI) was evaluated through 127 HA patient responses and relevance ratings by an expert panel (35 patients, 9 surgeons, 11 physiotherapists). Items with low relevance were omitted. Construct validity was assessed by the association of Hip-RSI scores to hip-related sporting function (HAGOS sport) and quality of life (iHOT12). Hip-RSI scores were compared between patients who had not returned, or returned to sport participation, previous sport, and sport performance. RESULTS: Item reduction resulted in a 6-item Hip-RSI scale with adequate content validity for the target population. Construct validity of the full and the item-reduced scale was demonstrated by correlation to HAGOS sport and iHOT12 (r 0.631-0.752). A gradient increase in Hip-RSI scores was found for patients returning to sport participation, previous sport, and sport performance. CONCLUSION: The short version of the Swedish Hip-RSI is a valid tool for the assessment of psychological readiness to RTS and can be recommended to be used in HA patients. Higher psychological readiness to RTS, assessed by the Hip-RSI, is found with increasing levels of return to sports following HA. LEVEL OF EVIDENCE: III.

Rapid decline of yearly number of hip arthroscopies in Sweden: a retrospective time series of 6,105 hip arthroscopies based on a national patient data register.

Background and purpose - Hip arthroscopies (HAs) have increased exponentially worldwide and are expected to continue rising. We describe time trends in HA procedures in Sweden (10 million inhabitants) between 2006 and 2018 with a focus on procedure rates, surgical procedures, and patient demographics such as age and sex distribution.Patients and methods - We retrospectively collected data from the Swedish National Patient Register (NPR) for all surgeries including surgical treatment codes considered relevant for HA from 2006 to 2018. Surgical codes were validated through a multiple-step procedure and classified into femoroacetabular impingement syndrome (FAIS) related or non-FAIS related procedure. Frequencies, sex differences, and time trends of surgical procedures and patient demographics are presented.Results - After validation of HA codes, 6,105 individual procedures, performed in 4,924 patients (mean age 34 years [SD 12]) were confirmed HAs and included in the analysis. Yearly HA procedure rates increased from 15 in 2006 to 884 in 2014, after which a steady decline was observed with 469 procedures in 2018. The majority (65%) of HAs was performed in males. Male patients were younger, and surgeries on males more frequently included an FAIS-related procedure.Interpretation - Similar to previous studies in other parts of the world, we found dramatic increases in HA procedures in Sweden between 2006 and 2014. Contrary to existing predictions, HA rates declined steadily after 2014, which may be explained by more restrictive patient selection based on refined surgical indications, increasing evidence, and clinical experience with the procedure.

Sociodemographic factors associated with HbA1c variability in type 2 diabetes: a prospective exploratory cohort study.

BACKGROUND: The associations between sociodemographic factors and HbA1c variability in type 2 diabetes are not yet established. Examining group differences in HbA1c variability may help identify patient characteristics related to diabetes management. The present study examined differences in baseline HbA1c and HbA1c variability between groups with regard to sex, level of education, civil status, age, and BMI, in a sample of individuals with type 2 diabetes. METHODS: The study was a prospective exploratory cohort study. Differences in HbA1c variability between sociodemographic groups were analyzed in 158 individuals. HbA1c variability was assessed as the standard deviation (SD) and coefficient of variation (CV) over five measured points, and a questionnaire was used to assess sociodemographic factors. RESULTS: The results showed significantly higher HbA1c variability in men compared to women (mean difference 1.44 mmol/mol [95% CI: 0.58 to 2.31]), and significantly higher HbA1c variability in individuals with a BMI characterized as obese compared to individuals with a BMI characterized as normal weight (mean difference 1.56 mmol/mol [95% CI: 0.25 to 2.88]). There were no significant associations between HbA1c variability and civil status or education. CONCLUSIONS: Men and individuals with obesity may be more vulnerable to future diabetic complications than other groups, since they have greater long-term glycemic variability.

High prevalence of hip and groin problems in professional ice hockey players, regardless of playing position.

PURPOSE: The prevalence of hip and groin problems in professional male ice hockey is unknown and suspected to differ between playing positions. The purpose of this study was to explore potential differences in the seasonal prevalence of hip and groin problems between playing positions in male elite ice hockey players and to explore the relationship between symptom duration and hip and groin function at the beginning of the new season. METHODS: Male ice hockey players [n = 329 (92 goalkeepers, 93 defensemen, 144 forwards), Mean age (SD): 24 (5)] from the professional leagues in Sweden responded to an online survey. The survey assessed presence of hip and groin problems (time loss and non-time loss) and symptom duration (categorized into 0, 1-6, or > 6 weeks) in the previous season, and current self-reported hip and groin function (Copenhagen Hip and Groin Outcome Score). RESULTS: During the previous season, 175 players (53.2%) had experienced hip and groin problems. Non time loss problems were experienced by 158 (48%) and time loss problems were experienced by 97 (29.5%) players. No significant differences between playing positions were found. Self-reported function differed significantly between players with different symptom duration and more disability was reported among players with longer symptom duration (p ≤ 0.002). CONCLUSION: Regardless of playing position, hip and groin problems were prevalent in male ice hockey players. Players with hip and groin problems during the previous season had significantly worse hip and groin function in the beginning of the new season, and longer symptom duration was associated with more disability. LEVEL OF EVIDENCE: III.

Dyskinesia and FAB score predict future falling in Parkinson's disease.

A growing body of research highlights the importance of cognition for prediction of falls in Parkinson's disease (PD). However, a previously proposed prediction model for future near falls and falls in PD, which includes history of near falls, tandem gait, and retropulsion, was developed without considering cognitive impairment. Therefore, by using a sample of 64 individuals with relatively mild PD and not excluding those with impaired cognition we aimed to externally validate the previously proposed model as well as to explore the value of additional predictors that also consider cognitive impairment. Since this validation study failed to support the proposed model in a PD sample including individuals with impaired global cognition, extended analyses generated a new model including dyskinesia (item 32 of Unified PD Rating Scale) and frontal lobe impairment (Frontal Assessment Battery-FAB) as significant independent predictors for future near falls and falls in PD. The discriminant ability of this new model was acceptable (AUC, 0. 80; 95% CI 0.68-0.91). Replacing the continuous FAB scores by a dichotomized version of FAB with a cut-off score ≤14 yielded slightly lower but still acceptable discriminant ability (AUC, 0. 79; 95% CI 0.68-0.91). Further studies are needed to test our new model and the proposed cut-off score of FAB in additional samples. Taken together, our observations suggest potentially important additions to the evidence base for clinical fall prediction in PD with concomitant cognitive impairment.

Occupational balance, work and life satisfaction in working cohabiting parents in Sweden.

INTRODUCTION: Occupational balance is the experience of having the right amount and right variation between work, domestic work, leisure, rest, and sleep. There is limited knowledge about which factors predict parents' combined occupational balance, and if the combined occupational balance is associated with work and life satisfaction. AIM: The first aim was to explore whether domestic work and childcare at baseline predicted combined occupational balance at follow-up among working cohabiting parents. The second aim was to explore associations between different combinations of occupational balance, and work and life satisfaction at follow-up. METHOD: A sample of 139 cohabiting parents responded to a questionnaire. Cohabiting parents can experience their occupational balance differently, and in the present study their experiences were divided into high and low after the median. The parents' balance was then combined in terms of high-high, high-low and low-low. Associations between childcare, domestic work, work and life satisfaction, and combined occupational balance were analysed with multinomial logistic regression analyses. RESULTS: Satisfaction with the division of domestic work predicted a high-high occupational balance in parent couples. Associations were found between high-high as well as high-low combined occupational balance and life satisfaction, and between high-high occupational balance and work satisfaction. CONCLUSIONS: It seems important for both parents in a couple to experience satisfaction with the division of domestic work to experience high occupational balance as well as work and life satisfaction.

Organisational factors and occupational balance in working parents in Sweden.

BACKGROUND: Parents with small children constitute a vulnerable group as they have an increased risk of sick leave due to stress-related disorders compared to adults without children. It has been shown that mothers and fathers to small children together spend more time in paid work than any other group, which could create negative stress and an experience of low occupational balance. AIM: The aim of this study was to examine associations between organisational factors and occupational balance among parents with small children in Sweden. METHODS: Data were collected by a survey including questions about occupational balance, organisational factors and age, sex, employment rate, work position, monthly household income, number of children at home, separation/divorce last five years and overtime. The total number of parents included in this study was 718 (490 mothers and 228 fathers). Logistic regression models were applied to examine the odds ratios for occupational balance in relation to organisational factors. RESULTS: Parents who experienced positive attitudes towards parenthood and parental leave among colleagues and managers were more likely to experience high occupational balance than parents who experienced negative or neutral attitudes. Having a clear structure for handover when absent from work was also strongly associated with high occupational balance. CONCLUSIONS: The result of the present study indicates that some organisational factors could be important for the occupational balance of parents with small children.

The effect of education and supervised exercise on physical activity, pain, quality of life and self-efficacy - an intervention study with a reference group.

BACKGROUND: Individuals with knee and hip osteoarthritis (OA) are less physically active than people in general, and many of these individuals have adopted a sedentary lifestyle. In this study we evaluate the outcome of education and supervised exercise on the level of physical activity in individuals with knee or hip OA. We also evaluate the effect on pain, quality of life and self-efficacy. METHODS: Of the 264 included individuals with knee or hip OA, 195 were allocated to the intervention group. The intervention group received education and supervised exercise that comprised information delivered by a physiotherapist and individually adapted exercises. The reference group consisted of 69 individuals with knee or hip OA awaiting joint replacement and receiving standard care. The primary outcome was physical activity (as measured with an accelerometer). The secondary outcomes were pain (Visual Analog Scale), quality of life (EQ-5D), and self-efficacy (Arthritis Self-Efficacy Scale, pain and other symptoms subscales). Participants in both groups were evaluated at baseline and after 3 months. The intervention group was also evaluated after 12 months. RESULTS: No differences were found in the number of minutes spent in sedentary or in physical activity between the intervention and reference groups when comparing the baseline and 3 month follow-up. However, there was a significant difference in mean change (mean diff; 95% CI; significance) between the intervention group and reference group favoring the intervention group with regard to pain (13; 7 to 19; p < 0.001), quality of life (- 0.17; - 0.24 to - 0.10; p < 0.001), self-efficacy/other symptoms (- 5; - 10 to - 0.3; p < 0.04), and self-efficacy/pain (- 7; - 13 to - 2; p < 0.01). Improvements in pain and quality of life in the intervention group persisted at the 12-month follow-up. CONCLUSIONS: Participation in an education and exercise program following the Swedish BOA program neither decreased the average amount of sedentary time nor increased the level of physical activity. However, participation in such a program resulted in decreased pain, increased quality of life, and increased self-efficacy. TRIAL REGISTRATION: The trial is registered with ClinicalTrials.gov. Registration number: NCT02022566 . Retrospectively registered 12/18/2013.

The relationship between physical workload and quality within line-based assembly.

Reducing costs and improvement of product quality are considered important to ensure productivity within a company. Quality deviations during production processes and ergonomics have previously shown to be associated. This study explored the relationship between physical workload and real (found during production processes) and potential (need of extra time and assistance to complete tasks) quality deviations in a line-based assembly plant. The physical workload on and the work rotation between 52 workstations were assessed. As the outcome, real and potential quality deviations were studied during 10 weeks. Results show that workstations with higher physical workload had significantly more real deviations compared to lower workload stations. Static work posture had significantly more potential deviations. Rotation between high and low workload was related to fewer quality deviations compared to rotation between only high workload stations. In conclusion, physical ergonomics seems to be related to real and potential quality deviation within line-based assembly. Practitioner Summary: To ensure good productivity in manufacturing industries, it is important to reduce costs and improve product quality. This study shows that high physical workload is associated with quality deviations and need of extra time and assistance to complete tasks within line-based assembly, which can be financially expensive for a company.

Gender inequality at home is associated with poorer health for women.

BACKGROUND: As more women have joined the work force, the difference in employment rate between men and women has decreased, in Sweden as well as many other countries. Despite this, traditional gender patterns regarding, for example, responsibility for household duties still remain. Women are on sick leave more often than men, and previous studies have indicated that an unequal split of household responsibilities and perceived gender inequality could be associated with negative health outcomes. AIMS: The aim of the present study was to explore whether an unequal distribution of responsibilities in the home was related to various health related outcomes among women. METHODS: A sample consisting of 837 women living in a relationship, and working at least 50% of full time, responded to a questionnaire including information about division of responsibilities at home as well as various psychological and physiological health related outcomes. RESULTS: The results showed that women living in relationships with perceived more unequal distribution of responsibility for house hold duties showed significantly higher levels of perceived stress, fatigue, physical/psychosomatic symptoms, and work family conflict compared with women living in more equal relationships. They also had significantly increased odds for insufficient time for various forms of recovery, which may further contribute to an increased risk of poor health. CONCLUSIONS: Although an increasing employment rate among women is valuable for both society and individuals, it is important to work towards greater gender equality at home to maintain this development without it having a negative effect on women's health and well-being.
