A cycling and education programme for the treatment of hip osteoarthritis: a quality improvement study

To lose weight or to weight the loss? Insights into the use of the body mass index in preoperative assessment before major orthopaedic surgery

The ERAS (Enhanced Recovery After Surgery) guidelines in major orthopaedic surgery do not address the issue of managing excess body weight in patients scheduled for hip and knee replacement or lumbar fusion. This aspect is relevant to practice due to the increasing number of obese individuals and to some evidence suggesting higher complication rates in patients with excess weight. There is a debate on whether obesity defined by the body mass index, i.e. the ratio of weight to squared height, can guide surgical eligibility and whether losing excess weight preoperatively can actually lead to better outcomes. In this practice development article, we explore opposing perspectives on the value of a high BMI as an indicator of increased preoperative risk and discuss the potential consequences of losing weight prior to a major orthopaedic surgery. The aim is to promote a conscious management of individuals with excess body fat based on the patient's overall health rather than BMI alone. In the absence of strong evidence on what is best to do, it is reasonable to suggest that any prehabilitation initiatives should not focus on a rigid weight loss mandate but on a multidisciplinary, multimodal, and personalised approach that does not necessarily include a reduction in body weight.

Chronic Pain Self-Management Strategies for Older Adults: An Integrative Review

INTRODUCTION

Due to the complex nature of chronic pain, especially in older adults, a biopsychosocial approach is more effective than an isolated approach for its management. Furthermore, when patients are actively engaged in their pain management, they are more likely to be successful than relying totally on others.

OBJECTIVE

To analyze the self-management strategies currently used by older adults with chronic pain.

METHOD

An integrative review was conducted through seven online databases, searching for scientific studies on this topic published in the last 10 years.

RESULTS AND CONCLUSION

Fifty-eight studies were included in the final sample. Research on chronic pain self-management for older adults has increased in recent years. Although a diversity of chronic physical painful conditions are being investigated, many conditions are still under-investigated. Online and in-person strategies are currently adopted, demonstrating similar results. Positive results are evidenced by strategies including health promotion, mind control, social participation and take-action fields. Major results come from a combination of strategies focusing on biopsychosocial aspects of pain management. Results include not only the reduction of pain itself, but increased self-efficacy, adoption of health behaviors and improvement of functionality, among others, i.e., improved QoL, despite pain.

CycLing and EducATion (CLEAT): protocol for a single centre randomised controlled trial of a cycling and education intervention versus standard physiotherapy care for the treatment of hip osteoarthritis

BACKGROUND

Osteoarthritis (OA) is a chronic degenerative joint disorder for which there is no known cure. Non-surgical management for people with mild-to-moderate hip OA focuses mainly on alleviating pain and maximising function via the National Institute for Health and Care Excellence (NICE) recommended combination of education and advice, exercise, and, where appropriate, weight loss. The CHAIN (Cycling against Hip pAIN) intervention is a group cycling and education intervention conceived as a way of implementing the NICE guidance.

METHODS

CycLing and EducATion (CLEAT) is a pragmatic, two parallel arm, randomised controlled trial comparing CHAIN with standard physiotherapy care for the treatment of mild-to-moderate hip OA. We will recruit 256 participants referred to the local NHS physiotherapy department over a 24-month recruitment period. Participants diagnosed with hip OA according to NICE guidance and meeting the criteria for GP exercise referral will be eligible to participate. Primary outcome is the difference in Hip Disability and Osteoarthritis Outcome Score (HOOS) function, daily living subscale between those receiving CHAIN and standard physiotherapy care. Secondary outcomes include performance-based functional measures (40 m walking, 30s chair stand and stair climb tests), ability for patient to self-care (patient activation measure) and self-reported health-related resource use including primary and secondary care contacts. The primary economic endpoint is the number of quality adjusted life years (QALYs) at 24 weeks follow-up. The study is funded by the National Institute for Health Research, Research for Patient Benefit PB-PG-0816-20033.

DISCUSSION

The literature identifies a lack of high-quality trials which inform on the content and design of education and exercise in the treatment of patients with hip OA and explore cost-effectiveness. CLEAT is a pragmatic trial which seeks to build further evidence of the clinical benefits of the CHAIN intervention compared to standard physiotherapy care within a randomised, controlled trial setting, and examine its cost-effectiveness.

A cycling and education intervention for the treatment of hip osteoarthritis: A quality improvement replication programme

Objectives:

The Cycling against Hip Pain programme is a 6-week exercise and education treatment pathway for people with hip osteoarthritis. Preliminary results of the Cycling against Hip Pain programme found significant improvements in clinical and patient-reported outcome measures for patients referred from primary care. This article evaluates the effectiveness of the changes made to the pathway in a quality improvement replication programme.

Methods:

The replicated Cycling against Hip Pain programme was delivered between February 2018 and September 2019 in a region of England with a high percentage of adults aged over 65 years. All participants were referred from the orthopaedic outpatient department of the funding hospital (secondary care). The programme was delivered at a local leisure centre and combined 30 min of education on osteoarthritis with 30 min of progressive static cycling, once a week for 6 weeks.

Results:

The participants on the replicated Cycling against Hip Pain programme did not differ from the original cohort in terms of age or pre-programme weight, however, presented with worse hip symptoms at baseline. Consistent with the findings from the original cohort, participants demonstrated significant improvements to their Oxford Hip Score, 30-s chair stand performance, Timed Up and Go score, Hip Osteoarthritis Outcome Score function and pain, EQ5D health rating, EQ5D-5L score and pain at rest and on weight bearing. In addition, participants reported an increase in knowledge, confidence and motivation to exercise.

Conclusion:

A 6-week cycling and education intervention for the treatment of hip osteoarthritis provided benefits to function, pain and quality of life for patients referred from secondary care. These results are consistent with findings from patients who were referred from primary care and further support the potential of the pathway in the conservative management of hip osteoarthritis.

Self-Management of Hip Osteoarthritis Five Years After a Cycling and Education Treatment Pathway

The Cycling against Hip Pain (CHAIN) programme is a six-week cycling and education treatment pathway for people with hip osteoarthritis. Preliminary results demonstrated significant improvements in clinical and patient-reported outcome measures following the course. Whilst the benefits of exercise for osteoarthritis are often reported in the short term, less is known about the long-term effects for this patient group. This study explores whether participants continued to self-manage their hip osteoarthritis five years after completing the course. A cross-sectional survey was conducted to collect data from participants who completed the CHAIN programme between October 2013 and February 2015 (n = 96). Questionnaires were sent by post in April 2019, and then non-responders were followed up again four weeks later. Eighty-three (87%) participants responded to the survey. Five years (range 4–6) after completion of a six-week cycling and education programme, 37 (45%) participants had not returned to their general practitioner for further treatment of their hip pain, and 47 (57%) had not pursued surgical intervention. All participants were still engaged in at least one physical activity per week and many reported that they had purchased a bike (29%), joined a gym (30%) or cycled regularly (indoor cycling 25%, outdoor cycling 24%). Eighty (96%) participants reported an increase in knowledge of self-managing their symptoms. The findings from this study suggest that many patients are motivated to self-manage their hip osteoarthritis, five years following a six-week cycling and education treatment pathway that encourages lifestyle change.

[Current trends and injuries in cycling: faster, further, e-bike?]

During the past decade, technical innovations (e.g., carbon as a new material, disk brakes, hydraulic shock absorbers, electric transmissions) and lifestyle changes have significantly influenced recreational and professional cycling. In contrast to the past, where ambitious leisure cyclists were primarily interested in the recreational value of nature and landscape, cyclists of all ages are nowadays increasingly focused on performance and self-optimization. Simultaneously, manufacturers have adapted to differing customer requirements: besides the traditional extremities of road and mountain bikes, many specialized models have been designed for special applications: trekking, cyclocross, gravel, full-suspension, single-track, hardtail, downhill, fatbike, etc. For biking fans who are no longer able to meet their own demands due to individual physical restrictions or defined health problems, electric-assist bikes (pedelecs or "e-bikes") were recently introduced. While these are becoming increasingly popular, they have also increased the number of accidents and injuries. The current work provides an update on relevant sport medical and orthopaedic challenges brought on by these developments in cycling.

Expectations and depression in patients who have undergone total hip arthroplasty in Japan: A prospective cohort study

BACKGROUND

Patients with hip osteoarthritis may be severely depressed preoperatively due to pain and limited daily-living activities. Hence, evaluating their expectations preoperatively might underestimate their true hopes regarding the upcoming total hip arthroplasty (THA).

AIM

We aimed to assess changes in patients' level of depression, understand their expectations and fulfillment, and identify factors affecting fulfillment.

METHOD

We performed a longitudinal study of 366 Japanese patients who had undergone THA during 2005-2006. Those with THA of the contralateral hip were excluded. Patients' expectations, fulfillment, depression, and physical function were assessed perperative and at 6 weeks and one year postoperatively using our own questionnaire, the Arthritis Impact Measurement Scale 2, and by the Oxford Hip Score . Logistic regression analysis was applied to identify independent predictors of expectation fulfillment.

RESULTS

At 6 weeks, 78.1% expressed expectation fulfillment and drastic alleviation of depression. Preoperative depression and fulfillment of patient expectations at 6 weeks were significant predictors of expectation fulfillment at 1 year (95% confidence intervals: 1.01-2.48 and 2.30-9.92, respectively.

CONCLUSIONS

It is worthwhile for health providers to investigate patients' expectations early in the postoperative period by considering their preoperative depression to confirm fulfillment of expectations.

Combining a high DHA multi-nutrient supplement with aerobic exercise: Protocol for a randomised controlled study assessing mobility and cognitive function in older women

There is a complex interplay between cognition and gait in older people, with declines in gait speed coexisting with, or preceding cognitive decline. Omega-3 fatty acids, B vitamins, vitamin E, phosphatidylserine, and Ginkgo Biloba show promise in preserving mobility and cognitive function in older adults. Exercise benefits mobility and there is evidence suggesting positive interactions between exercise and omega-3 fatty acids on physical and cognitive function in older adults. Non-frail or pre-frail females aged ≥60 years are included in a randomized placebo controlled study. Intervention groups are: high DHA multi-nutrient supplement and exercise, placebo supplement and exercise, high DHA multi-nutrient supplement, and placebo supplement. Dietary supplementation is 24 weeks. The exercise intervention, two cycle ergometer classes per week, is for the final 12 weeks. The primary outcome is habitual walking speed, secondary outcomes include gait variables under single and dual task, five times sit to stand, verbal and spatial memory, executive function, interference control and health related quality of life. Blood fatty acids, serum homocysteine, dietary intake, physical activity, and verbal intelligence are measured to assess compliance and control for confounding factors. The study is registered at www.clinicaltrials.gov (NCT03228550).

Downregulation of microRNA-9 increases matrix metalloproteinase-13 expression levels and facilitates osteoarthritis onset

Matrix metalloproteinase-13 (MMP-13) degrades collagen and other matrix components, thus playing a critical role in the development of osteoarthritis (OA). The expression level of microRNA-9 (miR-9) is significantly depressed in cartilage tissues of OA patients. Furthermore, bioinformatics analysis demonstrated complementary binding sites between miR-9 and MMP-13. The current study, therefore, investigated whether miR-9 is involved in regulating MMP-13 expression levels and OA onset. Cartilage tissues from OA patients and healthy individuals were compared for miR-9, MMP-13 and collagen type II α1 chain (Col2A1) expression levels. A dual luciferase gene reporter assay was performed to evaluate the association between miR-9 and MMP-13. Sodium iodoacetate was injected into the knee joint cartilage tissues to generate the rat OA model. The expression levels of miR-9, MMP-13 and Col2A1 were compared between the model and control rats. In addition, the OA model rats received miR-9 agomir for further expressional assay. Cartilage tissue samples from the OA patients exhibited significantly lower miR-9 and Col2A1 expression levels when compared with the control rats, whilst the expression level of MMP-13 was upregulated. As the target gene of miR-9, MMP-13 is under the targeted regulation of miR-9. The injection of miR-9 agomir into the knee joint cavity significantly depressed MMP-13 expression in the cartilage tissues of OA rats, with reduced collagen degradation and enhanced COL2A1. OA cartilage tissues have lower miR-9 expression and higher MMP-13 expression levels. Thus, miR-9 inhibits the expression level of MMP-13, decreases its inhibitory effects on COL2A1, and therefore contributes to antagonizing OA.
