The Burden of Osteoarthritis in the Middle East and North Africa Region From 1990 to 2019

The burden of knee osteoarthritis worldwide, regionally, and nationally from 1990 to 2019, along with an analysis of cross-national inequalities

OBJECTIVE

To describe the disease burden of knee osteoarthritis (KOA) globally, regionally, and in 204 countries by age, sex, and sociodemographic index (SDI) from 1990 to 2019, and to explore cross-national inequalities across SDI.

METHODS

The Global Burden of Disease (GBD) 2019 database collected data on KOA worldwide from 1990 to 2019, including prevalence, incidence, years lived with disability (YLDs). The average annual percentage change (AAPC) was used to measure temporal trends. In addition, the inequality slope index and the health concentration index were calculated to quantify the unequal distribution of the burden of KOA across 204 countries worldwide.

RESULTS

In 2019, the global age-standardized prevalence rate increased by 7.5% compared with 1990, and the age-standardized incidence rate increased by about 6.2%; The age-standardized YLDs rate increased by about 7.8%. In addition to the Republic of Korea and the United States of America, the disease burden of KOA has increased year by year in other countries around the world. The incidence of KOA was highest at ages 50-59, while the prevalence and rates of YLDs were highest at ages 75-84. The burden of KOA was higher in women than in men. Cross-country inequality suggests that the inequality in the burden of KOA between high SDI and low SDI countries becomes greater, and that countries with high SDI bear a disproportionately high burden.

CONCLUSION

The global KOA burden has risen steadily between 1990 and 2019, and cross-national inequality gaps remain large. Targeted measures must therefore be taken to address this inequality and the increasing global KOA disease burden.

Effects of the combination of pulsed electromagnetic field with progressive resistance exercise on knee osteoarthritis: A randomized controlled trial

BACKGROUND

Knee osteoarthritis (OA) is a common and disabling disease among the elderly population. The optimal conservative treatment for knee OA is not well established.

OBJECTIVE

This study aimed to assess the effectiveness of pulsed electromagnetic field (PEMF) combined with progressive resistance exercise (PRE) in improving physical function and pain in patients with knee OA.

METHODS

Thirty-four patients with knee OA (17 in each group) participated in a single-blind randomized control study. Patients were randomly assigned to receive 24 sessions of either combined PEMF and PRE (treatment group) or PRE only (control group). Patients were evaluated at pre-treatment, post-treatment (2 months), and at 3-month and 6-month follow-ups using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Numeric Pain Rating Scale (NPRS); walking speed and 5-times chair stand test. Mixed ANOVA was used for statistical analysis with Bonferroni adjustments.

RESULTS

There was no significant group-by-time interaction for any outcome (P> 0.05). However, both groups scored significantly higher on the NPRS and KOOS at post-treatment, 3-, and 6-month follow-up compared to their baseline. Further, both groups completed the 5-times chair stand test and walking speed test with significantly less time at all post-treatment time points than the pre-treatment. None of the study outcomes (NPRS, KOOS, walking speed, and 5 times chair stand) were significantly different between groups at any of the time points.

CONCLUSION

Both treatment options, PRE only versus PRE with PEMF, were equally effective in decreasing pain and improving physical function in patients with knee OA. This would suggest that the optimal parameters for PEMF that may show beneficial effects for knee OA when added to PRE training need to be determined.

Awareness and Management of Knee Pain and Osteoarthritis in Saudi Arabia: A Cross-Sectional Analysis

OBJECTIVE

 The study sought to assess the level of awareness regarding osteoarthritis and its management.

METHODS

 This study was cross-sectional, using data from a sample of 389 individuals from the central region of Saudi Arabia. The participants completed an online questionnaire and ensured anonymity.  Results: A total of 389 participants made up the sample for this study, which had a predominance of females (56.6%, n=220), a majority aged <50 years (66.6%, n=259), and most of them (51.7%, n=201) weighing 60-80 kg, substantial proportion lived in the Riyadh region (27.5%, n=107), with more than half (59.4%, n=231) having a university education and working in offices (28.3%, n=110). The majority (73.3%, n=285) of participants were married, and a vast majority (87.9%, n=342) were not smokers. The findings revealed that only 32.9% (n=128) of the participants had good knowledge about osteoarthritis. The study found that stiffness (80.2%, n=312) and swelling (97.9%, n = 381) are the most common signs and symptoms of osteoarthritis; the risk factors for osteoarthritis were genetic factors (79.7%, n=310) and age (91.3%, n=355). The treatment of osteoarthritis identified in the study included exercises such as swimming (85.1%, n=331), physical therapy (86.6%, n=337), and joint replacement surgery (92.0%, n=358). The study established a statistically significant association between age, education level, previous diagnosis of osteoarthritis, family history of osteoarthritis (p = 0.004, 0.001, 0.002, and 0.001, respectively), and level of knowledge about osteoarthritis. However, there was no statistically significant association between gender, marital status, smoking status, previous knee injuries, physical activity level, and the level of knowledge about osteoarthritis (p > 0.05).  Conclusion: Overall, the study revealed that 32.9% (n=128) of the participants had good knowledge about osteoarthritis. Participants aged 50-60 years, those with a university and post-graduate level of education, as well as those who had a previous diagnosis of osteoarthritis and those with a family history of osteoarthritis, had greater and better knowledge and awareness about osteoarthritis. Joint stiffness and swelling were identified, as the most common signs and symptoms of osteoarthritis. The risk factors identified in the study were genetic factors and age, while the treatment options noted by the study were exercise, such as swimming, physical therapy, and joint replacement surgery. The study notes the need for enhanced public awareness of the problems associated with osteoarthritis among the Saudi Arabian population.

The burden of neck pain among adults aged 70 years and older in Iran, 1990-2019

Background

Neck pain is a complex musculoskeletal disorder that can result in substantial morbidity. The present article presents the neck pain burden in Iranians who were at least 70 years old, from 1990 to 2019, by sex, age group, and province.

Methods

Publicly available information on the prevalence, incidence, and years lived with disability (YLD) caused by neck pain was extracted from the Global Burden of Disease study 2019. The estimates were all provided as counts and age-standardized rates (per 100,000), and included 95% uncertainty intervals.

Results

The point prevalence of neck pain in 2019 was 8710.6, while the incidence rate was 1334.7 per 100,000 population. That same year, there were number of 27.8 thousand YLDs and an YLD rate of 801.7 per 100,000. The prevalence, incidence, and YLD rates did not change substantially over the measurement period (1990-2019). The highest YLD rate was found in Tehran (960.9 per 100,000), while Kohgiluyeh and Boyer-Ahmad had the lowest (730.5 per 100,000). Females had slightly higher prevalent cases, incident cases, and YLDs, as well as their corresponding rates in 2019. In 2019, the number of prevalent cases, incident cases, and YLDs peaked in the 70-74 age group, for both sexes, and in all cases they reduced with age. In both 1990 and 2019, Iran had a higher YLD rate than that found among elderly adults in the Middle East and North Africa region.

Conclusions

The burden of neck pain in Iran has decreased slightly over the last three decades, but it still imposes a substantial burden and is higher than that found in the rest of the region. Therefore, preventive programs should be initiated at a young age to reduce the attributable burden later in life.

Research Trends and Foci in Osteoarthritis Pain from 2012 to 2022: Bibliometric and Visualization Study

Background

Osteoarthritis (OA) is a painful and complex joint disease. The unique mechanisms and potential interventions of OA-induced pain have attracted researchers' attention in recent years. Bibliometric and visualization analysis is a comprehensive scientific method that integrates mathematical and statistical approaches to explore research priorities in a specific field. However, there are few studies on OA pain using bibliometric analysis.

Purpose

This study aimed to explore research trends and hotspots in OA pain research field, offer practical guidance to researchers looking for top-notch scholars/institutions/countries, and provide suggestions for journal submissions by analyzing the existing literature.

Methods

Raw data were extracted from Web of Science Core Collection. Microsoft Excel, the R package "bibliometrix", VOSviewer and CiteSpace software were used to analyze data and visualize relevant results.

Results

A total of 2493 articles were included for further bibliometric and visualization analysis. During the investigated period, 2021 with 343 publications was the most productive year. Fillingim, Roger B. and Bennell, Kim L. with 32 articles were the most productive authors. Most publications were from the USA (797 articles, 20,727 citations). Rehabilitation and treatment of OA pain were the hotspots in OA pain research area. The top-contributing journal was Osteoarthritis and Cartilage. Boston University (91 articles; 4050 citations) was the most active institution.

Conclusion

The total publications of OA pain generally increasing over the time in the last decade, and the escalating rate remained a high level. This is the first comprehensive bibliometric study in OA pain research field, and it will offer practical guidance to researchers in this field.

Effectiveness of home-based conventional exercise and cryotherapy on daily living activities in patients with knee osteoarthritis: A randomized controlled clinical trial

BACKGROUND

Knee osteoarthritis (KOA) is a prevalent joint condition associated with aging that causes pain, disability, loss of function, and a decline in quality of life. This study aimed to evaluate the effectiveness of home-based conventional exercise and cryotherapy on daily living activities in patients with KOA.

METHODS

In this randomized controlled clinical trial, the patients who were diagnosed with KOA were assigned to 3 groups: an experimental group (n = 18), the control group 1 (n = 16), and the control group 2 (n = 15). Control and experimental groups engaged in a 2-month home-based exercise (HBE) program. The experimental group received cryotherapy along with HBE. In contrast, the patients in the second control group received regular therapeutic and physiotherapeutic services at the center. The patients were recruited from the Specialized Center for Rheumatic and Medical Rehabilitation in Duhok, Iraq.

RESULTS

The patients in the experimental group had statistically significant better daily activity functions compared to the first and second control groups in pain (2.22 vs 4.81 and 12.7; P < .0001), stiffness (0.39 vs 1.56 and 4.33; P < .0001), physical function (5.72 vs 13.31 and 38.13; P < .0001), and the total score (8.33 vs 19.69 and 55.33; P < .0001) at 2 months. The patients in the experimental and the first control groups had statistically significantly lower balance scores compared to the second control group at 2 months, 8.56 versus 9.30. At 3 months, similar patterns were observed for the daily activity function and balance.

CONCLUSIONS

This study showed that combining HBE and cryotherapy may be an effective technique to improve function among patients with KOA. Cryotherapy could be suggested as a complementary therapy for KOA patients.

Long-term survivorship and results in lower limb arthroplasty: a registry-based comparison study

INTRODUCTION

Popularity of joint replacement surgery due to ever aging population surges the demand for a proper national joint registry. Our Chinese University of Hong Kong - Prince of Wales Hospital (CUHK-PWH) joint registry has passed the 30^th year. The aims of this study are 1) summarize our territory-wide joint registry which has passed the 30th year since establishment and 2) compare our statistics with other major joint registries.

METHODS

Part 1 was to review the CUHK-PWH registry. Demographic characteristics of our patients who underwent knee and hip replacements had been summarized. Part 2 was a series of comparisons with registries from Sweden, UK, Australia and New Zealand.

RESULTS

CUHK-PWH registry captured 2889 primary total knee replacements (TKR) (110 (3.81%) revision) and 879 primary total hip replacements (THR) (107 (12.17%) revision). Median Surgery time of TKR was shorter than THR. Clinical outcome scores were much improved after surgery in both. Uncemented of hybrid in TKR were most popular in Australia (33.4%) and 40% in Sweden and UK. More than half of TKR and THR patients showed the highest percentage with ASA grade 2. New Zealand reflected the best cumulative percentage survival 20 years after surgery of 92.2%, 76.0%, 84.2% survivorship 20 years after TKR, unicompartmental knee replacement (UKR) and Hip.

CONCLUSION

A worldwide accepted patient-reported outcome measure (PROM) is recommended to develop to make comparisons among registries and studies feasible. Completeness of registry data is important and useful to improve surgical performance through data comparisons from different regions. Funding from government on sustaining registries is reflected. Registries from Asian countries have yet to be grown and reported.

Knowledge and Awareness Regarding Osteoarthritis and Its Factors in Hail Region, Saudi Arabia

Objectives Osteoarthritis (OA) is a common chronic degenerative joint disease linked to age, joint overuse abnormalities, and previous trauma. This research aims to assess the awareness levels, as well as the knowledge gap and misconceptions, about OA and its risk factors among the general population in Hail, Saudi Arabia. Methods The research adopted an observational cross-sectional method. Participants from Hail, Saudi Arabia, were recruited and then interviewed between 1 April and 15 July 2022. Adult males and females aged 18 or more were recruited via an online questionnaire using a Google Form link, inviting them to take part in a study concerning their knowledge of OA. The questionnaire was split into three sections. The first section covered demographic data, the second section contained general knowledge regarding OA, and the third section was made up of a 20-item quiz. The collected data was reviewed and then analyzed using the Statistical Package for Social Sciences (SPSS) Version 21 (IBM Corp., Armonk, NY, USA). The statistical methods employed were all two-tailed, with an alpha level of 0.05 considered significant if the P value was less than, or equal to, 0.05. Results Nine hundred six (906) eligible respondents completed the questionnaire. Participants ranged from 18 to 65 in age. More than 66% were female, while 77.5% had a university level of education or above. 13.6% had been diagnosed with OA. Overall, 40.9% of the study participants demonstrated a good knowledge level regarding OA, while 59.1% showed a poor knowledge level. Conclusion The study revealed that the awareness and knowledge levels of the general population in Hail about OA are unsatisfactory. Efforts are recommended to increase the awareness and knowledge of the population through public education, which in turn can lead to a reduction in risk factors and improved early detection of the disease.

Assessing the Burden of Osteoarthritis in Africa and the Middle East: A Rapid Evidence Assessment

Introduction/Objectives

This rapid evidence assessment (REA) was conducted to assess the burden of weight-bearing joint osteoarthritis in the developing countries of Africa and the Middle East.

Methods

Our REA methodology used a standardized search strategy to identify observational studies, published between January 1, 2010, and April 23, 2020, reporting on outcomes pertaining to the epidemiology and humanistic or economic burden of weight-bearing osteoarthritis. Relevant data from the included studies were used for qualitative analysis.

Results

Among the 20 publications reporting on knee osteoarthritis in 10 countries in Africa and the Middle East, 2 also reported on hip, and 1 on foot osteoarthritis. Prevalence of symptomatic/radiographic knee OA was 9-14% among rheumatology outpatients and 31-34% among those with mixed etiology osteoarthritis. Prevalence of knee OA diagnosed by magnetic resonance imaging was 70% among patients ≥40 years of age attending a hospital in Saudi Arabia. Quality-of-life outcomes were reported in 16 publications and suggested a substantial humanistic burden of osteoarthritis, including worse pain, function, and quality of life, and more depression; comparisons between studies were hampered by the variety of tools and scoring scales used, however. No studies reported on economic outcomes.

Conclusion

This REA indicates a substantial burden of osteoarthritis in weight-bearing joints in Africa and the Middle East, consistent with publications from other regions of the world.

External use of radon and sulfide mineral waters in the treat-ment of experimental arthrosis

Abstract: The article presents the results of studies of the effect of radon and sulfide min-eral waters (MW) on Wistar rats with experimental arthrosis. materials and methods. Rats were randomized into 4 groups. Group 1 consisted of intact rats (control group). In the remaining three groups, a model of knee arthrosis was reproduced using dexamethasone injections. Group 2 consisted of rats with untreated pathology. Group 3 consisted of rats using radon MW procedures, and group 4 consisted of rats using sulfide MW. Results. Morphological studies have determined that using radon and sulfide MW has a curative effect on the structural and functional organization of the joint and cartilage - the manifes-tations of inflammation in the knee joints are significantly reduced, dystrophic manifesta-tions disappear, and reparative processes in cartilage improve. There are signs of an im-provement in the state of metabolic processes in the body of rats: the balance in the lipid peroxidation and antioxidant systems is restored, and the indicators of the processes of energy supply of transmembrane transport (according to the activity of magnesium-dependent Na+/K+-ATP-ase and Ca2+-ATP-ase) and protein exchange.Conclusion. Based on the data obtained, it was concluded that both applied MWs have a unidirectional, but somewhat different in strength, curative effect on the course of experimental arthrosis, which is due to different mechanisms of the biological action of radon and hydrogen sul-fide. Keywords: experimental arthrosis; morphological and metabolic indicators; radon; hydrogen sulfide; mineral water.

Epidemiological trends of hand osteoarthritis from 1990 to 2019: Estimates from the 2019 Global Burden of Disease study

Background

Hand osteoarthritis (OA) is a chronic progressive disease characterized by disabling pain in the hand, with a high clinical burden. This study is designed to assess the epidemiological patterns of hand OA from 1990 to 2019 and analyze its secular trends based on sex, age, and socio-demographic index (SDI) at global, regional, and national levels.

Methods

Data on the incidence and disability-adjusted life years (DALYs) of hand OA were extracted from the 2019 Global Burden of Disease (GBD), and their respective age-standardized rates (ASRs) were calculated. The estimated annual percentage changes (EAPCs) in ASR were calculated to assess the prevalent trends of the incidence and DALYs of hand OA over the recent three decades. The relationship between ASR and SDI was analyzed by Pearson's correlation analysis.

Results

The incidence of hand OA increased from 371.30 million in 1990 to 676.02 million in 2019, increasing by 82.07%, whereas its age-standardized incidence rate (ASIR) decreased, with a downward trend [EAPC = -0.34; 95% confidence interval: -0.39--0.28]. With the changes in age, the incidence of hand OA exhibited a unimodal distribution before 70 years of age, peaking at 50-54 years, while its incidence had an upward trend in the >70 years age groups. Overall, hand OA-related DALYs increased in the recent 30 years. Meanwhile, its annual age-standardized DALY rate decreased, with EAPCs of -0.35 (95% CI, -0.38 --0.32). The DALYs increased with age. In 2019, the ASIR and age-standardized DALY rate were positively associated with the SDI regions. The incidence and DALYs presented predominance in female patients. The burden of hand OA over the recent three decades displayed obvious geographical diversity.

Conclusion

The incident cases of hand OA increased globally from 1990 to 2019, while the ASIR and age-standardized DALY rate decreased. However, in many countries and regions, there was a rising trend of ASR related to incidence and DALYs. In addition, the prevalence revealed geographical, sex, and age diversity. Thus, governments and medical institutions should reallocate medical resources based on the epidemiological characteristics of hand OA.

A Systematic Review of Psychometric Properties of Knee-Related Outcome Measures Translated, Cross-Culturally Adapted, and Validated in Arabic Language

During the previous two decades, patient-reported outcome measures (PROMs) have been well tested, and the tools were validated in different languages across the globe. This systematic review aimed to identify the knee disease-specific outcome tools in Arabic and evaluate their methodological quality of psychometric properties of the most promising tools based on the COSMIN checklist and PRISMA guidelines. Articles published in English, from the inception of databases until the date of search (10 August 2022), were included. Articles without at least one psychometric property (reliability, validity, and responsiveness) evaluation, and articles other than in the English language, were excluded from the study. The key terms [“Arabic” AND “Knee” AND (“Questionnaire” OR “Scale”)] were used in three databases, i.e., PubMed, Scopus, and Web of Science (WoS) in the advanced search strategy. Key terms were either in the title or abstract for PubMed. Key words were in the topic (TS) for WoS. COSMIN (COnsensus-based Standards for the selection of health Measurement Instruments) risk of bias checklist was used to evaluate the methodological quality of psychometric properties of the Arabic knee-related outcome measures. A total of 99 articles were identified in PubMed, SCOPUS, and WoS. After passing inclusion and exclusion criteria, 20 articles describing 22 scales from five countries were included in this review. The instruments validated in the Arabic language are Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), knee injury and osteoarthritis outcome score (KOOS), knee outcome survey- activities of daily living scale (KOS-ADLS), Oxford knee score (OKS), anterior knee pain scale, osteoarthritis of knee and hip health-related quality of life (OAKHQoL) scale, Lysholm knee score (LKS), international documentation committee subjective knee form (IKDC), intermittent and constant osteoarthritis pain (ICOAP) questionnaire, Kujala patellofemoral pain scoring system (PFPSS), anterior knee pain scale (AKPS) and osteoarthritis quality of life questionnaire (OAQoL),. All were found to have good test-retest reliability (Intra Correlation Coefficient), internal consistency (Cronbach’s alpha), and construct validity (Visual Analog Scale, Short Form-12, RAND-36, etc.). Of 20 instruments available to assess self-reported knee symptoms and function, 12 were validated in the Saudi Arabian population. Among them, KOS-ADLS is the best PROM to be used in various knee conditions, followed by KOOS and WOMAC. The assessed methodological quality of evidence says that the knee Arabic PROMs are reliable instruments to evaluate knee symptoms/function.
