Health-related quality of life and its influencing factors in Chinese with knee osteoarthritis

Electroacupuncture improves articular microcirculation and attenuates cartilage hypoxia in a male rabbit model of knee osteoarthritis

Background and aim

Hypoxia of the cartilage has been considered as a potential pathogenic factor in knee osteoarthritis (KOA). Studies have shown that impaired blood perfusion of joint leads to cartilage hypoxia. Electroacupuncture (EA) has proven effects on pain relief and improving microcirculation. This study aimed to explore the effect of EA on articular microcirculation and cartilage anoxic and the underlying mechanisms.

Procedures

Videman's method was used for 6 weeks to establish the KOA model. EA intervention was performed in four points around the knee for 3 weeks after KOA modeling. The Lequesne MG score was used to assess ethology. We recorded the oxygen tension of synovial fluid and the synovial microcirculation in vivo. HE-staining was used to assess cartilage morphology, and immunohistochemistry (IHC), Western blotting, and RT-PCR were used to assess expression of the major glycolytic enzymes glucosetransporter1 (GLUT1), pyruvate kinase M2(PKM2), and lactate dehydrogenase A (LDHA). Enzyme-linked immunosorbent assay (Elisa) was used to detect lactate content.

Results and conclusion

There was a significant decrease in Lequesne MG score and improvement in Mankin score after EA intervention (P < 0.01), a significant increase in synovial microcirculation (P < 0.05) and synovial fluid oxygen tension (P < 0.01), and there was significant decrease in the expression of GLUT1, PKM2 and LDHA (P < 0.01) and lactate (P < 0.05). This study suggested that EA ameliorate cartilage hypoxia and regulate glycolytic metabolism in chondrocytes in KOA model rabbits by improving articular microcirculation and oxygen tension.

Potential influencing factor on health-related quality of life in Japanese with knee osteoarthritis: the Locomotive syndrome and Health outcome in Aizu cohort Study (LOHAS)

PURPOSE

Several studies have investigated the factors that influence health-related quality of life in patients with knee osteoarthritis (KOA). This study aimed to identify and investigate the degree of involvement of potential factors influencing health-related quality of life (HRQOL) in an aged population with or without KOA.

METHODS

This multi-centered study included 651 participants who underwent health checkups in rural areas of Japan in 2010. The association between three component summary score of short-form 12 (physical component summary; PCS, mental component summary; MCS, and role-social component summary; RCS) and covariates were investigated using multiple linear regression model and calculated the scaled estimated regression coefficient.

RESULTS

Decreasing mobility, severity of knee pain, high pain-related self-efficacy (PSE), older age, high functional self-efficacy (FSE), and female gender had significant effect on PCS (p < 0.05). However, radiographic KOA had no influence on PCS. Presence of depression and body mass index had a significant influence on the MCS (p < 0.05). Decreasing mobility, presence of depression, PSE and older age had significant influence on the RCS (p < 0.05).

CONCLUSION

Our study results showed that physical, mental, and role/social QOL were affected by different influencing factors. Physical QOL was strongly influenced by subjective pain, physical performance, and self-efficacy, whereas radiographic KOA had no such effect. Depressive mood is associated with both mental and role/social QOL. The role/social QOL was predominantly affected by physical function and pain-related self-efficacy. Taking measure to improving functional ability and mental status might be the key factor to improve HRQOL in patient with KOA.

A comparison of jade moxibustion and traditional moxibustion in the treatment of knee osteoarthritis: A randomized clinical trial

BACKGROUND

This study was developed to compare the relative clinical efficacy of traditional moxibustion and Jade moxibustion in an effort to define the most effective approaches to treating knee osteoarthritis.

METHODS

In total, 94 patients were randomly assigned at a 1:1 ratio to the traditional moxibustion (TM) and Jade moxibustion (JM) groups. For JM, a jade kneepad was preheated for 3 minutes via electrification, with the jade in the kneepad being pressed onto acupoints when reaching an initial temperature of 46°C. For patients in the TM group, moxa cones were applied to acupoints for treatment. In total, 12 treatments were performed for patients in each group, with treatment being conducted 3 times per week. Study outcomes included 36-item short-form health survey and Western Ontario and McMaster Universities Osteoarthritis Index knee stiffness scores. In addition, serum levels of osteoarthritis-related cytokines were measured.

RESULTS

Overall, 89/94 patients completed this study, including 44 and 45 in the TM and JM groups, respectively. The 36-item short-form health survey physical functioning at weeks 12 and 24 (P = .033, 0.001), role-physical at weeks 4 and 24 (P = .030, 0.014), and role-emotional at week 4 (P = .045) were the only scores to differ significantly between the TM and JM groups. Western Ontario and McMaster Universities Osteoarthritis Index stiffness scores in the JM groups improved significantly relative to baseline at weeks 4, 8, 12, and 24 (all P < .01). The scores in the TM group differed significantly at all time points relative to baseline (all P < .01), with no differences between groups (all P > .05). Serum Interleukin-2 levels were lower in both groups (all P < .01). Cartilage oligomeric matrix protein and monocyte chemotactic protein-1 only differed significantly for patients treated via JM (P < .05, P < .01), with the same also being true for Interleukin-1β and Interleukin-8 in the TM group (all P < .01). No significant differences in other cytokines were observed, nor did they differ significantly between groups (all P > .05).

CONCLUSION

These results suggest that JM treatment can improve knee osteoarthritis patient quality of life, alleviating joint stiffness and restoring joint function with a level of efficacy comparable to TM.

The effect of femoral component valgus/varus angle on the mid-term efficacy of unicondylar knee arthroplasty

OBJECTIVE

To investigate the effect of femoral component valgus/varus angle (FCVA) on the mid-term outcome after unicondylar knee arthroplasty.

METHODS

Patients who underwent unicompartmental knee replacement in the Department of Bone and Joint Surgery, were retrospectively analyzed. According to the postoperative femoral prosthesis internal and external rotation angle, patients were divided into six groups the postoperative femoral prosthesis internal and external rotation angle: standard group, mildly abnormal group. The patients were followed up for 12 months, and complications were recorded during the follow-up period. The Range of motion (ROM), visual analog scale (VAS), and Knee society score (KSS) were compared between the six groups.

RESULTS

One hundred twenty-four patients with 124 knees were included in this study. There were no statistical differences in age, gender, body mass index, preoperative ROM, or preoperative VAS, KSS-C, and KSS-F scores among the six groups. Comparison of postoperative outcomes and efficacy grades showed that: (1) the differences in ROM grades, as well as VAS, KSS-C, and KSS-F efficacy at 12 months postoperatively were statistically significant in all six groups by rank sum test; and patients in the normal group had better ROM grades and KSS-F grades than those in the mild and severe abnormality groups; (2) During the follow-up, no patient records had other serious complications such as periprosthetic infection, prosthetic loosening, periprosthetic fracture, and spacer dislocation.

CONCLUSION

Controlling the femoral prosthetic internal rotation angle between 6° and 0° in unicompartmental knee replacements can lead to better mid-term outcomes for patients.

Assessment of the quality of life in patients with chronic degenerative osteoarticular diseases (gonarthrosis, coxarthrosis)

Quality of life is a multidimensional concept that refers to the individual perception of one's own life and that includes aspects of individual health (cultural, social or psychological). Arthrosis is a progressive condition that involves damage to cartilage, damage to the subchondral bone and changes in the synovial and periarticular structures. Material and method. The study aims to provide information on the impact of degenerative osteoarticular diseases (gonarthrosis and coxarthrosis) while assessing the health of the population in Suceava county (one of the most affected counties in Romania due to the COVID-19 pandemic) by studying a sample of the study population. Based on the results obtained, an analysis can be made and then general ideas about the entire population. Results and discussions. The application of the SF-36 questionnaire helps to identify ways to improve the quality of life of patients diagnosed with degenerative osteoarticular disorders, gonarthrosis and coxarthrosis, and to prevent the negative aspects. In the health field, quality of life is an indicator used to assess the physical, mental and social effects of illness and the applied medical treatments, as well as to analyze the needs of a patient during the illness. Conclusions. The suffering caused by this type of disease has an impact on the quality of life of patients, both physically and emotionally. A special role in assessing the quality of life in these patients is their emotional condition and the acceptance of their functional status, trying to improve it. The quality of life of patients with chronic degenerative osteoarticular diseases is a public health issue, by the duration of the disease, by family, social, economic and medical implications.

The Effect of Modified Tai Chi Exercises on the Physical Function and Quality of Life in Elderly Women With Knee Osteoarthritis

Background

Knee osteoarthritis (KOA) is the leading cause of pain and stiffness, affecting older adults’ physical function and quality of life. As a form of mind-body exercise, Tai Chi has been recommended as an exercise prescription for KOA patients. This study examined the effects and continuation of modified Tai Chi exercises on physical function and quality of life in elderly women with KOA.

Methods

We conducted a single-blind, randomized controlled trial (RCT) on 40 older women with KOA. The participants were randomized to a 12 weeks Tai Chi or control group. The Tai Chi group attended a kind of modified Tai Chi training sessions three times per week; the control group attended wellness education sessions once a week. The primary outcome was the Western Ontario and McMaster University Osteoarthritis Index (WOMAC). Secondary outcomes were the Berg Balance Scale (BBS), Timed Up and Go (TUG), Short-Form 36 (SF-36), Pittsburgh Sleep Quality of Index (PSQI), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS).

Results

After the 12-weeks the Tai Chi group showed significan improvement in the WOMAC pain (mean difference, −5.09 points, p = 0.001), WOMAC stiffness (mean difference, −3.60 points, p = 0.002), WOMAC physical function (mean difference, −11.21 points, p = 0.001) compared to the control group. In addition, the Tai Chi group had also significant improvement in the BBS (mean difference, 1.70 points, p = 0.008), TUG (mean difference, −0.52s, p = 0.001), SF-36PCS (mean difference, 7.60 points, p = 0.001), MCS (mean difference, 7.30 points, p = 0.001), PSQI (mean difference, −3.71 points, p = 0.001), SDS (mean difference, −5.37 points, p = 0.025) and SAS (mean difference, −5.06 points, p = 0.002).

Conclusion

The modified Tai Chi exercises are an effective treatment for improved physical function and quality of life in elderly women with KOA.

Relationship between social capital and quality of life among adult stroke patients: a cross-sectional study in Anhui Province, China

Objectives

Few studies have investigated the association between social capital and quality of life (QoL) among stroke patients. To address this research gap, we aimed to explore the association between social capital and QoL among stroke patients in Anhui Province, China.

Study design

Cross-sectional study.

Methods

This cross-sectional study was conducted using a multi-stage stratified random sampling method. The following data including demographic characteristics, health-related conditions, five dimensions of social capital status, and quality of life (QoL) were collected using a questionnaire. Generalized linear models were then used to determine the relationship between social capital and QoL after adjusting for confounding factors.

Results

A total of 390 participants were included for the final analysis in this study. Our results indicated that subjects with higher social capital including social connection (coefficient: 28.28, 95% CI: 19.39–37.16), social support (coefficient: 21.17, 95% CI: 10.63–31.71), trust (coefficient: 13.46, 95% CI: 2.73–24.19), reciprocity (coefficient: 25.56, 95% CI: 15.97–35.15), and cohesion (coefficient: 19.30, 95% CI: 9.90–28.70) had increased odds of reporting poor QoL when compared with lower social capital group. We also observed that the association between social capital and QoL varied across cities.

Conclusions

Our findings show that social capital is associated with QoL in adult stroke patients, suggesting that social capital may be significant for enhancing QoL among adults with stroke.

Osteoclasts secrete leukemia inhibitory factor to promote abnormal bone remodeling of subchondral bone in osteoarthritis

BACKGROUND

Osteoarthritis (OA) is a common chronic degenerative joint disease. At present, there is no effective treatment to check the progression of osteoarthritis. Osteochondral units are considered to be one of the most important structures affecting the occurrence and development of osteoarthritis. Osteoclasts mediate an increase in abnormal bone remodeling in subchondral bone in the early stage of osteoarthritis. Here, alendronate (ALN) that inhibit osteoclasts was used to study the regulatory effect of osteoclast-derived leukemia inhibitory factor (LIF) on early abnormal bone remodeling.

METHODS

This study involved 10-week-old wild-type female C57BL/6 mice and female SOST knockout (KO) mice that were divided into the sham, vehicle, ALN, and SOST KO groups.

RESULTS

The expression of LIF was found to decrease by inhibiting osteoclasts, and the histological OA score suggested that the degeneration of articular cartilage was attenuated. Additionally, micro-CT showed that osteoclasts inhibited in the early stage of OA could maintain the microstructure of the subchondral bone. The parameters of bone volume fraction (BV/TV), subchondral bone plate thickness (SBP.Th), and trabecular separation (Tb.Sp) of the treated group were better than those of the vehicle group.

CONCLUSIONS

These results suggested that downregulating the expression of sclerostin in osteocytes by secreting LIF from osteoclasts, activate the Wnt/β-catenin signaling pathway, and promote abnormal bone remodeling in OA. Therefore, clastokine LIF might be a potential molecular target to promote abnormal bone remodeling in early OA.

Acceptance of disability, coping style, perceived social support and quality of life among patients with chronic lymphedema: a cross-sectional study

OBJECTIVE

To examine acceptance of disability, coping style, perceived social support, and quality of life and to explore the relationships between acceptance of disability, coping style, perceived social support, and quality of life among Chinese patients with chronic lymphedema.

METHODS

Chronic lymphedema patients were recruited from five tertiary hospitals between May and July 2020 in China. Recruited patients were assessed for quality of life (QOL), acceptance of disability (AOD), coping styles, perceived social support (PSS), and sociodemographic and disease-related factors. Multivariate linear regression models were conducted to examine the multivariate effect of AOD, coping style, PSS, and sociodemographic and disease-related factors on QOL.

RESULTS

A total of 163 chronic lymphedema patients were recruited. The mean score of QOL was 2.23 (SD = 0.68). AOD, number of symptoms, acceptance-resignation, avoidance, degree of pain, PSS, and educational level were found to be significant predictors of QOL.

CONCLUSION

Chinese patients with chronic lymphedema had moderate levels of QOL. The QOL and specific domains of patients were affected by different factors. Special attention and targeted interventions should be given to improve patients' QOL.

Comparison of 10.6 μm Laser Moxibustion with Traditional Moxibustion in Knee Osteoarthritic Therapy: A Randomized Noninferiority Clinical Trial

Objective: To investigate the noninferiority of 10.6 μm laser moxibustion (LM) to traditional moxibustion (TM) in knee osteoarthritis (KOA). Methods: Ninety-two patients were recruited and randomly placed into one of two groups: 10.6 μm LM or TM in a 1:1 ratio. Each patient received 12 sessions of LM or TM, focusing on the ST-35 and Ashi acupoint. The sessions took place over 4 weeks, three times a week, and were followed up over 8 weeks. The endpoint outcomes were separated into two categories, primary and secondary. The primary endpoint was assessed at the end of the 4-week treatment, using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score. The secondary endpoint was evaluated at the end of the trial and consisted of the WOMAC function and stiffness score, visual analog pain [visual analog scale (VAS)] score, and 15-m walking time test. In addition, safety evaluation was performed throughout the trial. Results: Among the 92 randomized participants, 86 (93.48%) completed the trial; 43 in each group. The WOMAC pain score improved dramatically between the LM and TM groups, with a mean difference of 20.61 [95% confidence interval (CI): -2.28 to 43.50]. Given that the lower boundary of 95% CI was greater than -18.49, noninferiority was established. In addition, both LM and TM significantly decreased the WOMAC (pain, function and stiffness) score, VAS score (p < 0.05), and the 15-m walking time at the end of the trial. Interestingly, there were not significant differences between LM and TM (p > 0.05), suggesting that both are equally effective in treating KOA. Finally, among the 92 patients, 17 (18.48%) adverse effects were documented, namely 5 (10.87%) in the LM-treated group and 11 (26.09%) in the TM-treated group. Conclusions: 10.6 μm LM is not inferior to TM in treating KOA. Moreover, both LM and TM dramatically alleviated knee pain and enhanced function of knees.

Low Level Laser Therapy in Knee Osteoarthritis: A Narrative Review

Knee osteoarthritis (KOA) is the most common musculoskeletal disorder, especially in middle up to old age. KOA also results in many complications like changes in gait. Nowadays, changes in lifestyle and the reduced physical activity make people more vulnerable to KOA. Therefore, considering the increasing prevalence of KOA in many societies and the costs imposed on the afflicted people and their governments, providing conservative management approaches with a view to saving time and money is important. There are an assortment of conservative strategies in the management of KOA including low level laser therapy (LLLT). Since the introduction of lasers in the medical field in 1960, various types of lasers with widespread administration programs are used for medical conditions from cosmetics to surgery. However, there are conflicting findings on the application of lasers in osteoarthritis. To discuss the basis of the highest level of evidence, only systematic reviews with or without meta-analyses published up to January 2019 were included in the present work. In this regard, Scopus, PEDro, Medline, ISI Web of Science, Cochrane, PubMed, Irandoc, Iran Medex, Magiran, and SID were searched to retrieve articles in English or Persian. A total of 22 systematic reviews and meta-analyses were found, 14 of which were included in this study. The accepted articles were published between 1991 and up to 2019. The purpose of this narrative review was to investigate the effect of LLLT on pain and function in subjects with KOA. The result of the present review may help clinicians in making evidence-based decisions on optimal care in relation to administering LLLT.

Evaluation of health-related quality of life using EQ-5D in China during the COVID-19 pandemic

Objective

Since December 2019, an increasing number of cases of the 2019 novel coronavirus disease (COVID-19) infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been identified in Wuhan, Hubei Province, China. Now, more cases have been reported in 200 other countries and regions. The pandemic disease not only affects physical health who suffered it, but also affects the mental health of the general population. This study aims to know about the impact of the COVID-19 epidemic on the health-related quality of life (HRQOL) of living using EQ-5D in general population in China.

Methods

An online-based survey was developed and participants were recruited via social media. The questionnaires included demographic and socioeconomic data, health status, the condition epidemic situation and EQ-5D scale. The relationships of all factors and the scores of EQ-5D were analyzed. Logistic regression model were used to the five health dimensions.

Results

The respondents obtained a mean EQ-5D index score of 0.949 and a mean VAS score of 85.52.The most frequently reported problem were pain/discomfort (19.0%) and anxiety/depression (17.6%). Logistic regression models showed that the risk of pain/discomfort and anxiety/depression among people with aging, with chronic disease, lower income, epidemic effects, worry about get COVID-19 raised significantly.

Conclusion

The article provides important evidence on HRQOL during the COVID-19 pandemic. The risk of pain/discomfort and anxiety/depression in general population in China raised significantly with aging, with chronic disease, lower income, epidemic effects, worried about get COVID-19 during the COVID-19 pandemic. The results from each categorical data can be used for future healthcare measures among general population.
