Education and Social Support as Key Factors in Osteoarthritis Management Programs: A Scoping Review

Prevalence and Risk Factors of Osteoarthritis in Korea: A Cross-Sectional Study

Background and Objectives: The goal of this study is to determine the prevalence of knee osteoarthritis (OA) and risk factors for the disease in Korean adults over the age of 50, as well as to provide basic data for OA prevention through management. Materials and Methods: Based on 2010-2013 data from the Korean National Health and Nutrition Survey, 7962 adults over the age of 50 who participated in radiological tests and health surveys for the diagnosis of osteoarthritis were chosen as participants. Results: The risk factors for OA occurrence were investigated using complex sample multiple logistic regression analysis. According to the findings, the prevalence of knee OA in Korea was 33.3% in this study, with the risk of OA being higher in women, the elderly, people with a lower education level, and people with obesity. Conclusions: To reduce the incidence of OA, interventions and lifestyle changes are needed to prevent the onset of disease in participants with risk factors for OA, such as older women, low education levels, and obesity.

Genicular artery embolization for knee osteoarthritis: Results of the LipioJoint-1 trial

PURPOSE

The purpose of this study was to evaluate the safety and efficacy of transient genicular artery embolization (GAE) using an ethiodized oil-based emulsion for the treatment of knee osteoarthritis (KOA).

MATERIALS AND METHODS

This prospective, single-arm, open-label, multicenter, first-in-human cohort trial was registered on ClinicalTrials.gov (NCT04733092). The main inclusion criterion was diagnosis of KOA according to a visual analogue scale (VAS) pain score ≥ 40 mm (score range: 0-100 mm), despite conservative treatment for at least three months. Treatment efficacy was assessed using changes in VAS pain score, Mean Western Ontario & McMaster Universities osteoarthritis (WOMAC) function score (normalized to 100; score ranging from 0 to100) and outcome measures in rheumatoid arthritis clinical trials (OMERACT)-Osteoarthritis Research Society (OARSI) set of responder criteria.

RESULTS

Twenty-two consecutive participants (13 women; mean age, 66 ± 9 [standard deviation (SD)]) were included and underwent GAE. Emulsion consisted in a mixture of ioversol and ethiodized oil (ratio 1:3, respectively) prepared extemporaneously. The rate of serious adverse events attributed to GAE within one month was 5% (1/22), corresponding to reversible worsening of renal function. Immediate technical success rate was 100%. Mean VAS pain score dropped from 74.4 ± 16.5 (SD) mm at baseline to 37.2 ± 26.7 (SD) mm at three months (P < 0.001). Mean WOMAC function score (normalized to 100: score ranging from 0 to 100) decreased from 57.3 ± 17.1 (SD) at baseline to 33.5 ± 25.9 (SD) at three months (P < 0.001). At three months, 16 out of 22 participants (73%) were considered responders according to the OMERACT-OARSI set of responder criteria, including high improvement in either pain or WOMAC function, or improvement in both pain and WOMAC function.

CONCLUSION

GAE using an ethiodized oil-based emulsion is safe and improves pain and function in participants with KOA for at least three months.

Personalized Physical Activity Programs for the Management of Knee Osteoarthritis in Individuals with Obesity: A Patient-Centered Approach

Physical activity (PA) plays a vital role in knee osteoarthritis (KOA) management. However, engaging individuals with KOA in regular exercise is challenging, especially when they are affected by obesity. The aim of the current review is to elucidate how to increase adherence to exercise in this population. When implementing a PA program with patients with KOA and obesity, a specific multi-step approach can be adopted. In phase I (the baseline assessment), the patients' eligibility for exercise is ascertained and a physical fitness assessment, sarcopenic obesity screening and quantification of the pain experienced are undertaken. Phase II adopts a patient-centered approach in implementing a PA program that combines an active lifestyle (>6000 steps/day) with land- or water-based exercise programs performed over eight to twelve weeks, with a frequency of three to five sessions per week, each lasting 60 min. In phase III, several strategies can be used to increase the patients' adherence to higher levels of PA, including the following: (i) personalizing PA goal-setting and real-time monitoring; (ii) enhancing physical fitness and the management of sarcopenic obesity; (iii) building a sustainable environment and a supportive social network for an active lifestyle; and (iv) reducing pain, which can ameliorate the clinical severity of KOA and help with weight management in this population.

Influence of Risk Factors on the Well-Being of Elderly Women with Knee Osteoarthritis

Background and Objectives: Knee osteoarthritis (KOA) is a widespread chronic joint disease characterized by functional limitations and pain. Functioning restrictions exert a detrimental impact on societal integration, relationships, and psychological well-being, resulting in significant emotional distress in KOA patients. The objective of this study is to examine how various risk factors impact the emotional well-being of individuals with KOA. Materials and Methods: This prospective cross-sectional study involved 154 postmenopausal women treated at the Special Hospital for Rheumatic Diseases in Novi Sad, Serbia. The experimental group comprised 97 individuals with chronic knee pain and structural knee damage (Kellgren-Lawrence (KL) scale II-IV), while the control group had 53 individuals with chronic knee pain but no structural knee damage (KL scale 0-I). The collected data consisted of sociodemographic factors, general characteristics, associated diseases, and laboratory results. Adequate anthropometric measurements were conducted, and all subjects were required to complete the SF-36 RAND questionnaire. Results: The analysis identified several variables that independently influenced emotional well-being. These included pain intensity (beta (β) 0.21; 95% CI: 0.03-0.20; p < 0.01), social functioning (beta (β) 0.47; 95% CI: 0.23-0.43; p < 0.001), physical functioning (beta (β) 0.23; 95% CI: 0.04-0.21; p < 0.01), and education level (8-12 years: beta (β) 0.25; 95% CI: 1.47-9.41; p < 0.01; >12 years: beta (β) 0.27; 95% CI: 2.51-12.67; p < 0.01). However, the multivariate model revealed that only social functioning (beta (β) 0.57; 95% CI: 0.27-0.53; p < 0.001) and education level (8-12 years: beta (β) 0.21; 95% CI: 1.10-8.260; p < 0.05; >12 years: beta (β) 0.21; 95% CI: 1.18-10.30; p < 0.05) were significantly associated with emotional well-being in KOA patients. Conclusions: The findings of this study indicate that a reduced social functioning and a lower educational attainment are linked to a poorer emotional well-being among patients with KOA.

Effects of Self-management Program as Adjunctive to Usual Rehabilitation Exercise on Pain and Functional Outcomes in Knee Osteoarthritis: A Randomized Controlled Trial

BACKGROUND

Home-based exercise (HBE) and patient education (EDU) have been reported as beneficial additions to usual knee osteoarthritis (KOA) rehabilitation. However, previous trials mostly examined the effects of HBE and EDU separately. Thus, this study aimed to evaluate the effects of a structured combined HBE and EDU program in addition to usual KOA rehabilitation on pain score, functional mobility, and disability level.

STUDY DESIGN

A parallel-group, single-blinded randomized controlled trial.

METHODS

Eighty adults with KOA were randomly allocated to experimental (n=40) and control (n=40) groups. All participants underwent their usual physiotherapy care weekly for eight weeks. The experimental group received a structured HBE+EDU program to their usual care, while the control group performed home stretching exercises to equate treatment time. The Knee Injury and Osteoarthritis Outcome Score (KOOS) for the disability level, visual analogue scale (VAS) for pain, and timed up-and-go test (TUG) for mobility were measured pre-post intervention.

RESULTS

After eight weeks, the experimental group demonstrated significant improvements in the KOOS (all subscales), pain VAS, and TUG scores compared to baseline (P<0.001); meanwhile, only KOOS (activities of daily living and sports subscales) was significant in the control group. Relative to the control, the experimental group presented higher improvements (P<0.001) by 22.2%, 44.1%, and 15.7% for KOOS, pain VAS, and TUG, respectively.

CONCLUSION

Integrating the HBE+EDU program into usual KOA rehabilitation could reduce pain and disability, while it improved functional mobility. The finding of this study suggests a combination of a structured HBE and EDU program to be considered as part of mainstream KOA management.

Explaining the Concept of Self-Care Competence and Its Dimensions in Elderly Women with Knee Osteoarthritis in Iran: A Qualitative Study

Background

Chronic diseases, especially knee osteoarthritis, are more likely to occur among women with the increase in age. Self-care is an effective strategy for the management of disease in patients with knee osteoarthritis. Therefore, recognizing the dimensions of self-care competence in elderly women with knee osteoarthritis is particularly important for long-term management of the disease. The current study aimed to explain the concept and dimensions of self-care competence in elderly women with knee osteoarthritis.

Methods

This qualitative study was conducted using a conventional content analysis method proposed by Graneheim and Landman, from March to November 2020 in Mashhad (one of the largest cities in Iran). A total of 19 participants including 11 elderly women with knee osteoarthritis, 4 first-degree relatives and 4 medical staff were selected by the purposive sampling. Data were collected through in-depth and semi-structured interviews which continued until data saturation was reached. The MAXQDA (Version 10) was used to organize, code, and manage the data.

Findings

Three main themes including "symptom management", "personal growth" and "social cohesion" were emerged as the dimensions of self-care competence in elderly women with knee osteoarthritis.

Conclusions

Understanding the dimensions of self-care competence as one of the basic needs of the elderly women with knee osteoarthritis who live alone, is very important. Symptoms management, personal growth, and social cohesion as dimensions of self-care competence among this group of the elderly help to develop self-care competence interventions based on their needs.

Barriers and Challenges to Self-Care among Older Adults with Knee Osteoarthritis: A Qualitative Study

Background

Knee osteoarthritis (KOA) is a chronic disease causing disability in older adults. Self-care is an effective strategy for KOA management in older adults and clinicians have shown increased interest regarding the challenges of self-care activities in these patients. The present study aimed to explore the perception of older adults' patients with KOA regarding barriers and challenges faced in their self-care management.

Methods

In this qualitative study, data were collected using purposeful sampling and in-depth semi-structured interviews with 22 older adults with KOA, their first-degree caregivers, and medical team members in Mashhad, northeast Iran, from April to December 2020. All the interviews were transcribed verbatim. Interviews continued until reaching data saturation. All interviews were recorded. Data analysis was done using conventional content analysis according to the technique described by Graneheim and Lundman. The MAXQDA (Version 10) was used to organize, code, and manage the data.

Findings

Three main themes (confusion, confrontation with increasing stresses, and social rupture) were emerged as the barriers and challenges to self-care among older adults with KOA.

Conclusions

The results of this study provide a broad range of context-specific of barriers and challenges to self-care among older adults with KOA, which can be used for designing and implementing appropriate interventions to improve self-care in these patients.

Can genetics guide exercise prescriptions in osteoarthritis?

Osteoarthritis (OA) is the most common form of arthritis and has a multifactorial etiology. Current management for OA focuses on minimizing pain and functional loss, typically involving pharmacological, physical, psychosocial, and mind-body interventions. However, there remain challenges in determining which patients will benefit most from which interventions. Although exercise-based interventions are recommended as first-line treatments and are known to be beneficial for managing both the disease and illness of OA, the optimal exercise “prescription” is unknown, due in part to our limited understanding of the precise mechanisms underlying its action. Here we present our perspective on the potential role of genetics in guiding exercise prescription for persons with OA. We describe key publications in the areas of exercise and OA, genetics and OA, and exercise and genetics, and point to a paucity of knowledge at the intersection of exercise, genetics, and OA. We suggest there is emerging evidence to support the use of genetics and epigenetics to explain the beneficial effects of exercise for OA. We identify missing links in the existing research relating to exercise, genetics, and OA, and highlight epigenetics as a promising mechanism through which environmental exposures such as exercise may impact OA outcomes. We anticipate future studies will improve our understanding of how genetic and epigenetic factors mediate exercise-based interventions to support implementation and ultimately improve OA patient care.

Complex Lifestyle and Psychological Intervention in Knee Osteoarthritis: Scoping Review of Randomized Controlled Trials

Knee osteoarthritis (OA) causes pain, disability and poor quality of life in the elderly. The primary aim was to identify and map out the current evidence for randomised controlled trials (RCTs) on complex lifestyle and psychosocial interventions for knee OA. The secondary aim was to outline different components of complex lifestyle and psychosocial interventions. Our scoping review searched five databases from 2000 to 2021 where complex lifestyle or psychosocial interventions for patients with knee OA were compared to other interventions. Screening and data extraction were performed by two review authors independently and discrepancies resolved through consensus and in parallel with a third reviewer. A total of 38 articles were selected: 9 studied the effectiveness of psychological interventions; 11 were on self-management and lifestyle interventions; 18 looked at multifaceted interventions. This review highlights the substantial variation in knee OA interventions and the overall lack of quality in the current literature. Potential areas of future research, including identifying prognostic social factors, stratified care models, transdisciplinary care delivery and technology augmented interventions, have been identified. Further high-quality RCTs utilizing process evaluations and economic evaluation in accordance with the MRC guidelines are critical for the development of evidence-based knee OA programs globally.

Peer mentorship to improve self-management of hip and knee osteoarthritis: a randomised feasibility trial

OBJECTIVE

To determine the feasibility of conducting a randomised controlled trial (RCT) of a peer mentorship intervention to improve self-management of osteoarthritis (OA).

DESIGN

Six-month parallel group non-blinded randomised feasibility trial.

SETTING

One secondary care and one primary care UK National Health Service Trust.

PARTICIPANTS

Fifty adults aged ≥55 years old with hip and/or knee OA.

INTERVENTIONS

Participants were allocated 1:1 to the intervention or control group using an online randomisation service. Intervention group participants received usual care (information resources) and up to eight community-based self-management support sessions delivered by a peer mentor (trained volunteer with hip and/or knee OA). Control group participants received usual care only.

OUTCOME MEASURES

Key feasibility outcomes were participant and peer mentor recruitment and attrition, intervention completion and the sample size required for a definitive RCT. Based on these feasibility outcomes, four success criteria for proceeding to a definitive RCT were prespecified. Patient-reported outcomes were collected via questionnaires at baseline, 8 weeks and 6 months.

RESULTS

Ninety-six individuals were screened, 65 were eligible and 50 were randomised (25 per group). Of the 24 participants who commenced the intervention, 20 completed it. Four participants did not complete the 6-month questionnaire. Twenty-one individuals were eligible for the peer mentor role, 15 were trained and 5 withdrew prior to being matched with a participant. No intervention-related harms occurred. Allowing for 20% attrition, the sample size required for a definitive RCT was calculated as 170 participants. The intervention group showed improvements in self-management compared with the control group.

CONCLUSIONS

The feasibility outcomes achieved the prespecified criteria for proceeding to an RCT. The exploratory analyses suggest peer mentorship may improve OA self-management. An RCT of the OA peer mentorship intervention is therefore warranted with minor modifications to the intervention and trial procedures.

Patient experiences with videoconferencing as social contact and in follow-up from oncology nurses in primary health care

Patients with various forms of cancer often have unmet psychosocial support needs. By interpretative phenomenological approach, this study aimed to acquire a deeper understanding of home-living patients with cancer’s experience and meaning from videoconferencing in oncological nursing follow-up in primary healthcare and contact with networks. Six patients from rural Norway participated. Three themes emerged: (1) From skepticism to videoconferencing-enthusiasm; (2) Oncology nurses ensured tablet mastery and delivered close follow-up; and (3) Oncology nurses helped ensure general social support using videoconferencing. Oncology follow-up care in rural areas using videoconferencing may enhance care availability and provision of psychosocial support meeting patients’ needs.

Oncology nurses' lived experiences of video communication in follow-up care of home-living patients: A phenomenological study in rural Norway

PURPOSE

To explore the lived experiences of oncology nurses (ONs) during three months of virtual care provided through video conferencing (VC) in the follow-up care for home-living patients with cancer in rural Norway.

METHOD

An exploratory study employing a descriptive phenomenological approach conducted with a purposive sample of four ONs working in primary health care in three municipalities. Individual interviews based on open-ended questions about the ONs' experiences of VC use in follow-up care were analyzed using methodology inspired by Clark Moustakas. The COREQ checklist was utilized in this study.

RESULTS

ONs provided VC as a quality-promoting supplement to traditional follow-up. Their lived experiences of the phenomenon were described by the following themes: 1) Choice of VC based on care need considerations, 2) Use of VC on portable tablets facilitated contact and frequent follow-up, and 3) Adaption of relevant virtual care in person-centered and goal-oriented practice.

CONCLUSION

The use of VC may contribute to accessible and frequent quality care and reduce the ONs' travel time for home visits. This study points to a need to individualize and assess the appropriateness of virtual care in challenging cancer situations. Furthermore, there is a need for larger-scale studies on how VC may influence quality care.

Informal caregivers and persons with dementia's everyday life coping

This qualitative study explores informal caregivers' experiences of supporting persons with dementia's everyday life coping. In the future, there will be fewer health personnel, increased dementia prevalence and limited nursing home availability. Accordingly, close relatives may be compelled to assume greater care responsibilities. Knowledge concerning persons with dementia's everyday coping from the perspective of informal caregivers remains insufficient, despite these people's importance for those with dementia. This investigation analyses informal caregivers' perceived challenges and pleasures in providing care, how home health care affects everyday life coping and the factors that are most important to informal caregivers in supporting care receivers.

Expression of MiR-140 and MiR-199 in Synovia and its Correlation with the Progression of Knee Osteoarthritis

Background

The aim of this study was to explore the expression of miR-140 and miR-199 in synovia of patients with knee osteoarthritis (KOA) and its correlation with the progression of this disease. We used the Kellgren and Lawrence grading (KLG) system.

Material/Methods

There were 110 patients with early (KLG <2), middle (KLG=2) and late (KLG >2) stage KOA and 60 healthy individuals (control) included in this study.

Results

The relative expression levels of miR-140 (1.07±0.091) and miR-199 (1.03±0.110) in synovia of the control group were higher than those of KOA groups (0.511±0.130, 0.298±0.168) and the difference exhibited statistical significance (P<0.01). Expression of miR-140 in the middle and the late stage KOA groups (0.322±0.118 and 0.110±0.088 respectively) were 58.80% and 81.29% lower, respectively, compared to the early stage KOA group (0.588±0.172), which was significant (P<0.05). Expression of miR-199 in the middle and the late stage KOA groups (0.210±0.124 and 0.056±0.068 respectively) were 39.41% (P<0.05) and 83.72% (P<0.01) respectively lower than that in the early KOA group (0.344±0.147). The severity of OA was significantly negatively correlated with the expressions of miR-140 and miR-199 (r=−0.859, P<0.05; r=−0.724, P<0.001 respectively). Matrix metalloproteinase (MMP)-3 levels of the early stage, middle stage and late stage KOA groups were 1.320±0.118, 1.488±0.210, and 1.955±0.023 respectively; and IL-1β mRNA was 1.401±0.204, 1.522±0.210, and 1.889±0.217 respectively, which were obviously higher than those in the control group (1.020±0.085), (P<0.05).

Conclusions

Expression levels of miR-140 and miR-199 in synovia might act as an early diagnostic marker for KOA. These expression levels might also act as indicators of OA progression to some extent.
