Currently, no disease-modifying therapies are approved for osteoarthritis (OA) use. One obstacle to trial success in this field has been our existing endpoints' limited validity and responsiveness. To overcome this impasse, the Foundation for the NIH OA Biomarkers Consortium is focused on investigating biomarkers for a prognostic context of use for subsequent qualification through regulatory agencies. This narrative review describes this activity and the work underway, focusing on the PROGRESS OA study. [ABSTRACT FROM AUTHOR]

The article discusses the intersection of medical statistics and artificial intelligence (AI), highlighting the challenges faced in applying AI to biomedical data analysis and the need for a balance between learning from data and ensuring accuracy, robustness, and reproducibility of data-driven conclusions in medical research. It emphasizes the unique features of AI that make it powerful yet statistically vulnerable and explores challenges related to population inference.

The author discusses the status of the National Health Service (NHS) in the U.K. as of July 13, 2023. Topics covered include various issues of patient crowding, ambulances' inability in handling over patients , and emergency department waiting times, the primary cause of long-term underinvestment in health services, and NHS's dependence on nursing homes and aged care facilities. Also noted are the miseries and frustrations all of these bring to patients and exhausted health professionals.

The lifetime risk of symptomatic hand osteoarthritis (OA) is 39.8%, with one in two women and one in four men developing the disease by age 85 years and no disease-modifying drug (DMOAD) available so far. Intra-articular (IA) therapy is one of the options commonly used for symptomatic alleviation of OA disease as it can circumvent systemic exposure and potential side effects of oral medications. The current narrative review focuses on the efficacy and safety profiles of the currently available IA agents in hand OA (thumb-base OA or interphalangeal OA) such as corticosteroids and hyaluronic acid (HA), as well as the efficacy and safety of IA investigational injectates in phase 2/3 clinical trials such as prolotherapy, platelet-rich plasma, stem cells, infliximab, interferon-? and botulinum toxin, based on the published randomized controlled trials on PubMed database. The limited published literature revealed the short-term symptomatic benefits of corticosteroids in interphalangeal OA while long-term data are lacking. Most of the short-term studies showed no significant difference between corticosteroids and hyaluronic acid in thumb-base OA, usually with a faster onset of pain relief in the corticosteroid group and a slower but greater (statistically insignificant) pain improvement in the HA group. The majority of studies in investigational agents were limited by small sample size, short-term follow-up, and presence of serious side effects. In addition, we reported higher accuracy rates of drug administrations under imaging guidance than landmark guidance (blind method), and then briefly describe challenges for the long-term efficacy and prospects of IA therapeutics.

Premise: The study of phenotypic divergence of, and selection on, functional traits in closely related taxa provides the opportunity to detect the role of natural selection in driving diversification. If the strength or direction of selection in field populations differs between taxa in a pattern that is consistent with the phenotypic difference between them, then natural selection reinforces the divergence. Few studies have sought evidence for such concordance for physiological traits. Methods: Herbarium specimen records were used to detect phenological differences between sister taxa independent of the effects on flowering time of long‐term variation in the climate across collection sites. In the field, physiological divergence in photosynthetic rate, transpiration rate, and instantaneous water‐use efficiency were recorded during vegetative growth and flowering in 13 field populations of two taxon pairs of Clarkia, each comprising a self‐pollinating and a outcrossing taxon. Results: Historically, each selfing taxon flowered earlier than its outcrossing sister taxon, independent of the effects of local long‐term climatic conditions. Sister taxa differed in all focal traits, but the degree and (in one case) the direction of divergence depended on life stage. In general, self‐pollinating taxa had higher gas exchange rates, consistent with their earlier maturation. In 6 of 18 comparisons, patterns of selection were concordant with the phenotypic divergence (or lack thereof) between sister taxa. Conclusions: Patterns of selection on physiological traits measured in heterogeneous conditions do not reliably reflect divergence between sister taxa, underscoring the need for replicated studies of the direction of selection within and among taxa.

An editorial is presented on the need for a booster to restore high antibody levels both to reduce infection with new variants and to minimize hospitalization and death. Topics include restore high antibody levels both to reduce infection with new variants and to minimize hospitalization and death; and emergence of the omicron variant has increased the urgency of these booster doses.

Musculoskeletal pain such as osteoarthritis (OA) and low back pain (LBP) are very common and contribute to enormous burden and societal costs, despite dramatic therapeutic advances over recent decades. Novel approaches and targeted therapies are required to satisfy the urgent unmet medical need of musculoskeletal pain relief in both conditions. Nerve growth factor (NGF) inhibitors have utilized novel mechanisms different from conventional drugs, which have a variety of gastrointestinal, cardiac, or renal adverse effects. Several phase 2/3 studies have been accomplished for these drugs, such as tanezumab, fasinumab, and tyrosine receptor kinase A (TrkA) inhibitors. We searched the literature using the PubMed database and clinical trials using ClinicalTrials.gov to identify original papers, meta-analyses as well as ongoing clinical trials assessing the efficacy and safety profile of these drugs. In this narrative review, we briefly overview the disease burden of musculoskeletal pain, the role of NGF signaling and its receptors in the genesis of pain, and the mechanisms of action of inhibitors of NGF signaling and downstream pathways, and then discuss the efficacy and safety of each investigational drug in OA and LBP. Finally, we briefly review two serious adverse effects of NGF inhibitors, namely rapidly progressive OA and sympathetic system effects, and conclude with possible barriers and potential research directions to overcome these.

Background: Arthroscopic surgery for femoroacetabular impingement syndrome (FAI) is known to lead to self-reported symptom improvement. In the context of surgical interventions with known contextual effects and no true sham comparator trials, it is important to ascertain outcomes that are less susceptible to placebo effects. The primary aim of this trial was to determine if study participants with FAI who have hip arthroscopy demonstrate greater improvements in delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) index between baseline and 12 months, compared to participants who undergo physiotherapist-led management.Methods: Multi-centre, pragmatic, two-arm superiority randomised controlled trial comparing physiotherapist-led management to hip arthroscopy for FAI. FAI participants were recruited from participating orthopaedic surgeons clinics, and randomly allocated to receive either physiotherapist-led conservative care or surgery. The surgical intervention was arthroscopic FAI surgery. The physiotherapist-led conservative management was an individualised physiotherapy program, named Personalised Hip Therapy (PHT). The primary outcome measure was change in dGEMRIC score between baseline and 12 months. Secondary outcomes included a range of patient-reported outcomes and structural measures relevant to FAI pathoanatomy and hip osteoarthritis development. Interventions were compared by intention-to-treat analysis.Results: Ninety-nine participants were recruited, of mean age 33 years and 58% male. Primary outcome data were available for 53 participants (27 in surgical group, 26 in PHT). The adjusted group difference in change at 12 months in dGEMRIC was -59 ms (95%CI - 137.9 to - 19.6) (p = 0.14) favouring PHT. Hip-related quality of life (iHOT-33) showed improvements in both groups with the adjusted between-group difference at 12 months showing a statistically and clinically important improvement in arthroscopy of 14 units (95% CI 5.6 to 23.9) (p = 0.003).Conclusion: The primary outcome of dGEMRIC showed no statistically significant difference between PHT and arthroscopic hip surgery at 12 months of follow-up. Patients treated with surgery reported greater benefits in symptoms at 12 months compared to PHT, but these benefits are not explained by better hip cartilage metabolism.Trial Registration Details: Australia New Zealand Clinical Trials Registry reference: ACTRN12615001177549 .

Background: Lesbian, gay, bisexual and trans (LGBT) individuals have been shown to have poorer health when compared to those who identified as heterosexual. Additionally, they encounter barriers that deter participation in sports. Aim: To understand the experiences of LGBT individuals who participate in physical activity with peers. Method: An exploratory-descriptive qualitative (EDQ) study with data collected via face-to-face interviews from 12 participants. Data were thematically analysed to identify findings. Findings: exercising with peers represents a healthier way to meet people. Participants experienced improved physical, mental and social health. Conclusion: Engaging with a peer group for physical activity can have a transformational effect on members of the LGBT community, impacting on all aspects of their wellbeing. Nurses, and other health professionals, should be aware of the multifaceted benefits that exercising with a peer group can have, using their regular interactions with this patient group to recommend peer-supported exercise.

Osteoarthritis (OA) is a complex musculoskeletal disease and a leading cause of pain and disability worldwide. Hip and knee OA alone are major contributors to global disability, having notable effects on individual well-being, increasing the reliance of individuals on health-care services and contributing to a rise in the socioeconomic burden. Consistent, coordinated and tailored approaches are important for providing appropriate care to all people with OA, but despite the scale of the challenge many individuals are still not offered the safe, best-evidence treatments recommended for OA care. This Review discusses the core priority treatments for OA, including exercise and physical activity, weight-loss, education and support for self-management. Additional physical or psychological evidence-based adjunctive therapies and combined therapies that can be used to tailor individual programmes are also discussed. These options include cognitive behavioural therapy, heat therapy, walking aids and splints, manual therapies and transcutaneous electrical nerve stimulation. International examples of OA treatment options, models of care and resources available are also given. Many challenges still need to be addressed to advance the uptake of these conditions, including further discussion around the risks and costs involved with all treatments. [ABSTRACT FROM AUTHOR]

Objectives: Dietary supplements are increasingly used by people with osteoarthritis. Boswellia serrata extract, curcumin, pine bark extract and methylsulfonylmethane have been identified as having the largest effects for symptomatic relief in a systematic review. It is important to understand whether any pharmacokinetic interactions are among the major constituents of these supplements so as to provide information when considering the combination use of these supplements. The aim of this study was to investigate the pharmacokinetics of the constituents alone and in combination. Methods: This study was a randomized, open‐label, single‐dose, four‐treatment, four‐period, crossover study with 1‐week washout. The pharmacokinetics of the constituents of these supplements when dosed in combination with methylsulfonylmethane were compared to being administered alone. Plasma samples were obtained over 24 h from 16 healthy participants. Eight major constituents were analysed using a validated ultra‐high‐performance liquid chromatography–tandem mass spectrometry assay. Key findings: The pharmacokinetics of each constituent was characterized, and there were no significant differences in the pharmacokinetic profiles of the constituents when administered as a combination, relative to the constituents when administered alone (P > 0.05). Conclusions: These data suggest that interactions between the major constituents of this supplement combination are unlikely and therefore could be investigated to manage patients with osteoarthritis without significant concerns for possible pharmacokinetic interactions.

Objectives: The paper reports on an empirical study of Health and Wellbeing Boards (HWBs) in England. Established by the Health and Social Care Act 2012, HWBs act as place-based hubs for leaders in health, social care, local government and other sectors to come together to address health improvement and the wider determinants of health. Methods: We conducted a three-year study of HWBs (2015–2017) in five localities across England. This involved collecting qualitative data from semi-structured interviews with key actors in the HWBs at strategic and operational levels, and focus group sessions with voluntary-sector participants at each HWB. Results: HWBs have largely followed the path of previous partnerships in terms of a lack of clear aims and objectives, lack of ownership and accountability by partners, and an absence of any significant impact on health outcomes. Conclusions: Many of the features of unsuccessful partnership working were largely displayed by HWBs. Boards require more executive power and ownership from the bottom up if they are to have any real impact. [ABSTRACT FROM AUTHOR]

Objective: Neighbourhood deprivation has been found to be associated with many health conditions, but its association with low back pain (LBP) and arthritis is unclear. This study aimed to examine the association between neighbourhood deprivation with LBP and arthritis, and its potential interaction with individual socioeconomic status (SES) on these outcomes. Methods: Monozygotic (MZ) twins from the Washington State Twin Registry were used to control for genetic and common environmental factors that could otherwise confound the purported relationship. Multilevel models were employed to examine the association between neighbourhood deprivation as well as individual-level SES with LBP/arthritis, adjusting for age, sex, body mass index (BMI) and residence rurality. Results: There were 6,380 individuals in the LBP sample and 2,030 individuals in the arthritis sample. Neighbourhood deprivation was not associated with LBP (P = 0.26) or arthritis (P = 0.61), and neither was its interaction with individual-level SES. People without a bachelor's degree were more likely to report LBP (OR 1.44, 95% CI 1.26–1.65) or both LBP and arthritis (OR 1.67, 95% CI 1.14–2.45) than those with a bachelor's degree, but not for arthritis alone (P = 0.17). Household income was not significantly associated with LBP (P = 0.16) or arthritis (p = 0.23) independent of age, sex, and BMI. Conclusion: Our study did not find significant associations between neighbourhood deprivation and the presence of LBP or arthritis. More research using multilevel modelling to investigate neighbourhood effects on LBP and arthritis is recommended. [ABSTRACT FROM AUTHOR]

An editorial is presented to the article osteoarthritis (OA) has an extraordinarily prevalent and disabling disease. Topics include society has being impacted FOR underemployment and the opioid epidemic, and health care systems have as a consequence of the trajectory of increasing joint replacement requirements; and acupuncture has a component of traditional East Asian medicine and has been used as a healing practice.

Osteoarthritis is a leading cause of disability and source of societal cost in older adults. With an ageing and increasingly obese population, this syndrome is becoming even more prevalent than in previous decades. In recent years, we have gained important insights into the cause and pathogenesis of pain in osteoarthritis. The diagnosis of osteoarthritis is clinically based despite the widespread overuse of imaging methods. Management should be tailored to the presenting individual and focus on core treatments, including self-management and education, exercise, and weight loss as relevant. Surgery should be reserved for those that have not responded appropriately to less invasive methods. Prevention and disease modification are areas being targeted by various research endeavours, which have indicated great potential thus far. This narrative Seminar provides an update on the pathogenesis, diagnosis, management, and future research on osteoarthritis for a clinical audience. [ABSTRACT FROM AUTHOR]

Background: Intra-articular corticosteroids relieve osteoarthritis pain, but rapid systemic absorption limits efficacy. FX006, a novel, microsphere-based, extended-release triamcinolone acetonide (TA) formulation, prolongs TA joint residence and reduces systemic exposure compared with standard TA crystalline suspension (TAcs). We assessed symptomatic benefits and safety of FX006 compared with saline-solution placebo and TAcs.Methods: In this Phase-3, multicenter, double-blinded, 24-week study, adults ≥40 years of age with knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) and average-daily-pain (ADP)-intensity scores of ≥5 and ≤9 (0 to 10 numeric rating scale) were centrally randomized (1:1:1) to a single intra-articular injection of FX006 (32 mg), saline-solution placebo, or TAcs (40 mg). The primary end point was change from baseline to week 12 in weekly mean ADP-intensity scores for FX006 compared with saline-solution placebo. Secondary end points were area-under-effect (AUE) curves of the change in weekly mean ADP-intensity scores from baseline to week 12 for FX006 compared with saline-solution placebo, AUE curves of the change in weekly mean ADP-intensity scores from baseline to week 12 for FX006 compared with TAcs, change in weekly mean ADP-intensity scores from baseline to week 12 for FX006 compared with TAcs, and AUE curves of the change in weekly mean ADP-intensity scores from baseline to week 24 for FX006 compared with saline-solution placebo. Exploratory end points included week-12 changes in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Knee Injury and Osteoarthritis Outcome Score Quality of Life (KOOS-QOL) subscale scores for FX006 compared with saline-solution placebo and TAcs. Adverse events were elicited at each inpatient visit.Results: The primary end point was met. Among 484 treated patients (n = 161 for FX006, n = 162 for saline-solution placebo, and n = 161 for TAcs), FX006 provided significant week-12 improvement in ADP intensity compared with that observed for saline-solution placebo (least-squares mean change from baseline: -3.12 versus -2.14; p < 0.0001) indicating ∼50% improvement. FX006 afforded improvements over saline-solution placebo for all secondary and exploratory end points (p < 0.05). Improvements in osteoarthritis pain were not significant for FX006 compared with TAcs using the ADP-based secondary measures. Exploratory analyses of WOMAC-A, B, and C and KOOS-QOL subscales favored FX006 (p ≤ 0.05). Adverse events were generally mild, occurring at similar frequencies across treatments.Conclusions: FX006 provided significant, clinically meaningful pain reduction compared with saline-solution placebo at week 12 (primary end point).Level Of Evidence: Therapeutic Level I.

Aim: to examine ward staff perceptions on the role of the ‘hospital at day’ advanced nurse practitioner (ANP). This term is used locally to refer to a model first introduced into ‘hospital at night’ teams, in response to changes in working patterns of junior doctors, where an advanced nurse practitioner is based on the ward—the model was subsequently rolled out to daytime teams. Methods: a qualitative descriptive phenomenological approach was adopted to carry out this study with a purposive sample of ten participants. Participants were interviewed individually using semi-structured interviews to gain insights into their perceptions on the role of the ANP, following Colaizzi’s analytical model of data analysis. Findings: four major themes were identified. The first overarching theme was effectiveness of the ANP role. There was evidence that the role was not only clinically effective in the ward but also in relation to organisational priorities such as impact on patient flow. Secondly it was acknowledged that having an ANP based on the ward and as a ‘constant’ in the ward area, when medical teams rotate, provides team stability and improves the functioning of the ward area. Despite the positivity recognised, the third theme identified that having a ward-based ANP may affect skill acquisition and development and may lead to the ‘de-skilling’ of staff. Lastly it was acknowledged that there remains an overall confusion about the role of the ANP. Conclusion: the themes identified reflect what is already known about the wider perceived role of the ANP. Moreover, this study adds to the limited literature available specifically on the benefits of the ANP within ‘hospital at day’ roles. [ABSTRACT FROM AUTHOR]

Background: Familial cases of early-onset osteoarthritis (OA) are rare although the exact prevalence is unknown. Early recognition of underlying OA-associated disorders is vital for targeted treatment, when available, and genetic counselling, in case of skeletal dysplasias. Currently, there is no clear guidance on how best to investigate families affected by early-onset OA. Methods: We investigated a family with multiple members affected by early-onset OA (age at onset ≤ 40 years). Clinical and demographic characteristics were collected, followed by laboratory investigations screening for a range of potential OA-associated disorders, and whole genome sequencing in selected individuals. Results: Seventeen members of the family were included (7 affected and 10 non-affected). There was an even split between the two sexes and two participants were under 18 years old. No pattern of abnormality was seen in the laboratory investigation that could explain the OA phenotype in the family. Whole-genome sequencing was perfomed in one participant and analysed for likely pathogenic variants in genes known to be associated with skeletal dysplasias. A heterozygous variant in the COL2A1 gene was identified (p.Arg519Cys). Confirmatory tests were performed in five additional participants (four affected and one unaffected). Conclusion: The methodology used in this study, including the clinical pathway and bioinformatics pipeline, could be applied to other families affected by early-onset OA. [ABSTRACT FROM AUTHOR]

The article offers information on osteoarthritis (OA) pathogenesis. Topics discussed include the relation of obesity and aging to risk of symptomatic knee OA, total knee joint replacement and the similarity of a rheumatoid arthritis to congestive heart failure. Information on latent class analysis (LCA) approach is offered.

Management of osteoarthritis should be based on a combination of non-drug and drug treatments targeted towards prevention, modifying risk and disease progression. Obesity is the most important modifiable risk factor, so losing weight in addition to land- and water-based exercise and strength training is important. While paracetamol can be tried, guidelines recommend non-steroidal anti-inflammatory drugs as first-line treatment for osteoarthritis. If there are concerns about the adverse effects of oral treatment, particularly in older patients or those with comorbidities, topical non-steroidal anti-inflammatory drugs can be used. Glucosamine does not appear to be any better than placebo for pain. Its effect on the structural progression of disease when taken alone or in combination with chondroitin is uncertain. Fish oil has not been found to reduce the structural progression of knee arthritis. Surgical interventions should be avoided in the first instance, with arthroscopic procedures not showing benefit over sham procedures or optimised physical and medical therapy. Joint replacement surgery should be considered for severe osteoarthritis. [ABSTRACT FROM AUTHOR]

The article describes the case of a 67 year old woman with right-knee osteoarthritis referred for treatment of her knee pain. The patient inquired whether hyaluronate injection therapy may be appropriate for her although the specialist recommends weight loss and exercise and counsel her on the appropriate use of viscosupplements. It notes that present evidence base will not advocate the use of intraarticular hyaluronate for managing knee osteoarthritis.

We are transforming the educational strategy at the Harvard T. H. Chan School of Public Health guided by 5 principles: (1) development of T-shaped competencies (breadth across fields, depth in primary fields), (2) flexible and modular design accommodating different needs through the life-cycle, (3) greater experiential learning, (4) 3 levels of education (informative, formative, and transformative learning), and (5)integrated instructional design (online, in person, and in the field). We aim to create an arc of education resulting in continuous learning. We seek to bridge the research versus education dichotomy and create research–teaching congruence, adapting the values of peer review and quality assessment that we routinely accept for grant and article review to education.

Background Context: There are no previous epidemiologic studies examining associations between physical activity and imaging-detected lumbar zygapophyseal joint osteoarthritis (ZJO) in a community-based sample.Purpose: To determine whether physical activity is associated with prevalent lumbar ZJO on computed tomography (CT).Study Design/setting: A community-based cross-sectional study.Patient Sample: Four hundred twenty-four older adults from the Framingham Heart Study.Outcome Measures: Participants received standardized CT assessments of lumbar ZJO at the L2-S1 levels. Severe lumbar ZJO was defined according to the presence and/or degree of joint space narrowing, osteophytosis, articular process hypertrophy, articular erosions, subchondral cysts, and intra-articular vacuum phenomenon. This definition of lumbar ZJO was based entirely on CT imaging findings and did not include any clinical criteria such as low back pain.Methods: Physical activity was measured using the Physical Activity Index, which estimate hours per day typically spent in these activity categories: sleeping, sitting, slight activity, moderate activity, and heavy activity. Participants reported on usual frequency of walking, running, swimming, and weightlifting. We used multivariable logistic regression to examine associations between self-reported activity and severe lumbar ZJO, while adjusting for key covariates including age, sex, height, and weight.Results: In multivariable analyses, ordinal categories of heavy physical activity duration per day were significantly associated with severe lumbar ZJO (p for trend=.04), with the greatest risk observed for the category 3 or more hours per day, odds ratio 2.13 (95% confidence interval [CI] 0.97-4.67). When heavy activity was modeled as a continuous independent variable, each hour was independently associated with 1.19 times the odds of severe lumbar ZJO (95% CI 1.03-1.38, p=.02). Less vigorous types of physical activity and the type of exercise were not associated with severe lumbar ZJO. Older age, lesser height, and greater weight were independently and significantly associated with severe lumbar ZJO. In multivariable models predicting lumbar ZJO, neither model discrimination nor reclassification improved with the addition of physical activity variables, compared with a multivariable model including age, sex, height, and weight.Conclusions: Our findings demonstrate a statistically significant cross-sectional association between heavy physical activity and CT-detected severe lumbar ZJO. However, the additional discriminatory capability of heavy physical activity above and beyond that contributed by other factors was negligible. [ABSTRACT FROM AUTHOR]

Introduction: Globally, the rate of opioid prescription is high for chronic musculoskeletal conditions despite guidelines recommending against their use as their adverse effects outweigh their modest benefit. Deprescribing opioids is a complex process that can be hindered by multiple prescriber- and patient-related barriers. These include fear of the process of, or outcomes from, weaning medications, or a lack of ongoing support. Thus, involving patients, their carers, and healthcare professionals (HCPs) in the development of consumer materials that can educate and provide support for patients and HCPs over the deprescribing process is critical to ensure that the resources have high readability, usability, and acceptability to the population of interest. Objective: This study aimed to (1) develop two educational consumer leaflets to support opioid tapering in older people with low back pain (LBP) and hip or knee osteoarthritis (HoKOA), and (2) evaluate the perceived usability, acceptability, and credibility of the consumer leaflets from the perspective of consumers and HCPs. Design: This was an observational survey involving a consumer review panel and an HCP review panel. Participants: 30 consumers (and/or their carers) and 20 HCPs were included in the study. Consumers were people older than 65 years of age who were currently experiencing LBP or HoKOA, and with no HCP background. Carers were people who provided unpaid care, support, or assistance to an individual meeting the inclusion criteria for consumers. HCPs included physiotherapists (n = 9), pharmacists (n = 7), an orthopaedic surgeon (n = 1), a rheumatologist (n = 1), nurse practitioner (n = 1) and a general practitioner (n = 1), all with at least three years of clinical experience and who reported working closely with this target patient population within the last 12 months. Methods: Prototypes of two educational consumer leaflets (a brochure and a personal plan) were developed by a team of LBP, OA, and geriatric pharmacotherapy researchers and clinicians. The leaflet prototypes were evaluated by two separate chronological review panels involving (1) consumers and/or their carers, and (2) HCPs. Data collection for both panels occurred via an online survey. Outcomes were the perceived usability, acceptability, and credibility of the consumer leaflets. Feedback received from the consumer panel was used to refine the leaflets, before circulating the leaflets for further review by the HCP panel. Additional feedback from the HCP review panel was then used to refine the final versions of the consumer leaflets. Results: Both consumers and HCPs perceived the leaflets and personal plan to be usable, acceptable, and credible. Consumers rated the brochure against several categories, which scored between 53 and 97% positive responses. Similarly, the overall feedback provided by HCPs was 85–100% positive. The modified System Usability Scale scores obtained from HCPs was 55–95% positive, indicating excellent usability. Feedback for the personal plan from both HCPs and consumers was largely positive, with consumers providing the highest positive ratings (80–93%). While feedback for HCPs was also high, we did identify that prescribers were hesitant to provide the plan to patients frequently (no positive responses). Conclusions: This study led to the development of a leaflet and personal plan to support the reduction of opioid use in older people with LBP or HoKOA. The development of the consumer leaflets incorporated feedback provided by HCPs and consumers to maximise clinical effectiveness and future intervention implementation. Plain Language Summary: Opioids are medications that are often used to treat severe or chronic pain. However, they can have serious adverse effects and are not usually recommended for long-term use. This study aimed to create educational materials for patients with chronic low back pain or hip or knee osteoarthritis who are taking opioids and to evaluate the materials' perceived usability, acceptability, and credibility from the perspective of both healthcare professionals (HCPs) and patients. The materials included a brochure and a personal plan and were developed by a team of researchers and clinicians. Both materials were evaluated by HCPs and patients in separate review panels. The brochure and personal plan were found to be usable, acceptable, and credible by both groups. The materials were created to support patients in reducing their opioid use and were refined based on feedback from both HCPs and patients. The materials may be useful in supporting the complex process of tapering off opioids, which can be hindered by various barriers related to both patients and HCPs. [ABSTRACT FROM AUTHOR]

Osteoarthritis (OA) is a highly prevalent, disabling disease, with a commensurate tremendous individual and socioeconomic burden. This Perspectives article focuses on the burden of OA for the individual, the health-care system and society, to draw attention to the magnitude of the current problem with some reference to projected figures. We have an urgent opportunity to make fundamental changes to the way we care for individuals with OA that will have an effect upon the direct and indirect costs of this disease. By focusing on the burden of this prevalent, disabling, and costly disease, we hope to highlight the opportunity for shifts in health-care policy towards prevention and chronic-disease management.

Osteoarthritis affects 7% of the global population, more than 500 million people worldwide, with women disproportionately affected by the condition.[1] The number of people affected globally rose by 48% from 1990 to 2019, and in 2019 osteoarthritis was the 15th highest cause of years lived with disability (YLDs) worldwide and was responsible for 2% of the total global YLDs.[[1]] Although YLDs for osteoarthritis are higher in high Socio-demographic Index (SDI) countries than in middle SDI regions (about 525 vs 220 YLDs per 100 000 population), since 1990 the rate of change in YLDs has been far greater in middle SDI countries than in high SDI countries (89% vs 48%).[[1]] Osteoarthritis is a leading cause of disability in older adults and the trends of an ageing population and increasing obesity are likely to compound this. The condition does not feature in global strategic plans for non-communicable diseases, yet osteoarthritis commonly coexists with heart disease, diabetes, and mental health problems and can worsen the morbidity and mortality associated with these conditions.[4] Patients with osteoarthritis also report that their concerns are downplayed by health practitioners.[5] Therapeutic nihilism may affect patients and practitioners, with misperceptions that osteoarthritis is an inevitable part of ageing and that there are no effective treatments. 46, 2016, 160-167 5 S Alami, I Boutron, D Desjeux, Patients' and practitioners' views of knee osteoarthritis and its management: a qualitative interview study.

Topics discussed include results of a clinical trial in one military hospital in the U.S. involving patients with OK who underwent physical therapy, comparison with a treatment using glucocorticoid injections, and impact on the patients' well-being and the quality of care.

Introduction: More than half of the patients with moderate and severe osteoarthritis (OA) report unsatisfactory pain relief, requiring consideration of intra‐articular (IA) injections as the second‐line management. Ultrasound‐guided IA injection has proven evidence of higher accuracy in administering IA injectates into the joints than landmark‐guided or blind IA injections. However, questions remain about translating higher accuracy rates of ultrasound‐guided injection into better clinical improvements. Therefore, we examined the symptomatic benefits (pain, function and patient satisfaction) of ultrasound‐guided injection in knee, hip and hand OA compared with blind injections by synthesising a systematic review and meta‐analysis of randomised controlled trials (RCT). Methods: PubMed, Medline and Embase databases were searched for eligible studies from their inception to August 28, 2023. Results: Out of 295 records, our meta‐analysis included four RCTs (338 patients with knee OA), demonstrating significant improvement in procedural pain [−0.89 (95% CI −1.25, −0.53)], pain at follow‐up [−0.51 (95% CI −0.98, −0.04)] and function [1.30 (95% CI 0.86, 1.73)], favouring ultrasound guidance. One single study showed higher patient satisfaction with ultrasound guidance. Conclusion: Ultrasound‐guided IA injection provided superior clinical outcomes compared with landmark‐guided IA injection. [ABSTRACT FROM AUTHOR]

Metformin has been shown to modulate meta-inflammation, an important pathogenesis in knee osteoarthritis (OA). The study aimed to test the association between regular metformin use with total knee replacement (TKR) in patients with diabetes. This is a retrospective study with electronic records retrieved in Hong Kong public primary care. Patients with diabetes aged ≥ 45 who visited during 2007 to 2010, were followed up for a four-year period from 2011 to 2014 to determine the incidence of TKR. Propensity score matching based on age, sex, co-medications and chronic conditions was conducted to adjust for confounding. Cox regression was implemented to examine the association between metformin use and TKR. In total, 196,930 patients were eligible and 93,330 regular metformin users (defined as ≥ 4 prescriptions over the previous year) and non-users were matched. Among 46,665 regular users, 184 TKRs were conducted, 17.1% fewer than that among non-users. Cox regression showed that regular metformin users had a 19%-lower hazard of TKR [hazard ratio (HR) = 0.81, 95% confidence interval: 0.67 to 0.98, P = 0.033], with a dose–response relationship. Findings suggest a potential protective effect of metformin on knee OA progression and later TKR incidence among diabetic patients. [ABSTRACT FROM AUTHOR]

Background: Guidelines encourage engagement in self‐care activities for osteoarthritis (OA), but there are gaps in consumers' knowledge about suitable choices for self‐care. Community pharmacists are in an ideal position to contribute to OA management through screening and supporting evidence‐based pain management choices. Prior research established an association between health literacy and advice‐seeking and appropriateness of analgesics choices (both lower in participants with limited health literacy) amongst people living with OA. This article explores the implications of these data for pharmacists in OA management. Methods: A national online survey was conducted amongst 628 adults aged 45–74 years, currently residing in Australia, with self‐reported symptoms of OA. All data were collected using a customized online questionnaire, which was completed only once. 'Self‐reported symptoms of OA' was based on six validated screening questions to identify people with OA without a formal clinical diagnosis. Results: Respondents matched the typical profile of people diagnosed with OA; more than half were female (56%), knees (59%) and hips (31%) were the primary affected joints and 74% were either overweight or obese. Self‐identification of OA was limited (41%). Overall, 38% self‐managed their pain, and limited health literacy was associated with less advice‐seeking. Efficacy and ease of use were the main reasons cited for prompting use across all classes of nonprescription analgesic, with less than 20% reporting recommendation from a pharmacist. Participants were managing their pain with an average of 1.74 (95% confidence interval: 1.60–1.88) analgesics, but 73% reported inadequate pain relief and 54% had disrupted sleep. Conclusion: Our findings highlight three key themes: lack of self‐identification of OA, suboptimal pain relief and limited use of the community pharmacist as a source of management advice. Equipping community pharmacists with tools to identify OA could bridge this gap. More research is needed to determine if it will improve consumers' ability to appropriately manage OA pain. Patient or Public Contribution: Consumers living with OA contributed to the study outcomes, reviewed the survey questionnaire for face validity and advised on plain language terminology.

Objective: To explain the factors contributing to the gap in depression between employed arthritis patients with and without paid sick leave. Methods: Blinder-Oaxaca decomposition analysis was used to identify factors that explain the gap in the experience of depressive symptoms among arthritis patients with paid and unpaid sick leave. Data from the 2018 National Health Interview Survey, USA, was used. Results: A total of 7189 of the NHIS survey participants given the diagnosis of arthritis were identified, of which 39% were male and 61% were female, with mean age of 63.5 years. The decomposition findings suggest patients in the unpaid sick leave group were more likely to report depressive symptoms compared to patients with paid sick leave. The major contributors to the gap in the report of depressive symptoms are sex (female) and annual income (less than 35,000 USD). Conclusion: Findings suggest that the absence of paid sick leave is a key determinant for experiencing depressive symptoms among individuals with arthritis. The provision of paid sick leave may reduce report of depressive symptoms among employed arthritis patients in the USA. Key Points: • Individuals with arthritis are consistently at greater risk of depression and unemployment as compared to individuals without arthritis. • To date greater emphasis is put on determinants of unemployment, while there is no available data on benefits associated with being employed, such as sick leave, and how it affects mental health. • Patients with unpaid sick leave appear to experience more persistent depressive symptoms than patients with access to paid sick leave. • To tackle burden of depression among arthritis patients, provision of paid sick leave may be an effective intervention.

Background: To evaluate the effectiveness and safety of technology-assisted rehabilitation following total hip/knee replacement (THR/TKR).Methods: Six electronic databases were searched without language or time restrictions for relevant studies: MEDLINE, EMBASE, Cochrane Library, CINAHL, SPORTDiscus, Physiotherapy Evidence Database (PEDro); from inception to November 7th, 2018. Two reviewers independently applied inclusion criteria to select eligible randomised controlled trials (RCTs) that investigated the effectiveness of technology-based interventions, compared with usual care or no intervention for people undergoing THR/TKR. Two reviewers independently extracted trial details (e.g. patients' profile, intervention, outcomes, attrition and adverse events). Study methodological quality was assessed using the PEDro scale. Quality of evidence was critically appraised using the Grading of Recommendations, Assessment, Development and Evaluation approach.Results: We identified 21 eligible studies assessing telerehabilitation, game- or web-based therapy. There were 17 studies (N = 2188) in post-TKR rehabilitation and 4 studies (N = 783) in post-THR rehabilitation. Compared to usual care, technology-based intervention was more effective in reducing pain (mean difference (MD): - 0.25; 95% confidence interval (CI): - 0.48, - 0.02; moderate evidence) and improving function measured with the timed up-and-go test (MD: -7.03; 95% CI: - 11.18, - 2.88) in people undergoing TKR. No between-group differences were observed in rates of hospital readmissions or treatment-related adverse events (AEs) in those studies.Conclusion: There is moderate-quality of evidence showed technology-assisted rehabilitation, in particular, telerehabilitation, results in a statistically significant improvement in pain; and low-quality of evidence for the improvement in functional mobility in people undergoing TKR. The effects were however too small to be clinically significant. For THR, there is very limited low-quality evidence shows no significant effects. [ABSTRACT FROM AUTHOR]

Cam femoroacetabular impingement (FAI) syndrome is associated with hip osteoarthritis (OA) development. Hip shape features, derived from statistical shape modeling (SSM), are predictive for OA incidence, progression, and arthroplasty. Currently, no three‐dimensional (3D) SSM studies have investigated whether there are cam shape differences between male and female patients, which may be of potential clinical relevance for FAI syndrome assessments. This study analyzed sex‐specific cam location and shape in FAI syndrome patients from clinical magnetic resonance examinations (M:F 56:41, age: 16–63 years) using 3D focused shape modeling‐based segmentation (CamMorph) and partial least squares regression to obtain shape features (latent variables [LVs]) of cam morphology. Two‐way analysis of variance tests were used to assess cam LV data for sex and cam volume severity differences. There was no significant interaction between sex and cam volume severity for the LV data. A sex main effect was significant for LV 1 (cam size) and LV 2 (cam location) with medium to large effect sizes (p < 0.001, d > 0.75). Mean results revealed males presented with a superior‐focused cam, whereas females presented with an anterior‐focused cam. When stratified by cam volume, cam morphologies were located superiorly in male and anteriorly in female FAI syndrome patients with negligible, mild, or moderate cam volumes. Both male and female FAI syndrome patients with major cam volumes had a global cam distribution. In conclusion, sex‐specific cam location differences are present in FAI syndrome patients with negligible, mild, and moderate cam volumes, whereas major cam volumes were globally distributed in both male and female patients.
