Use of recommended osteoarthritis pain treatment by older adults

Biomaterial-Guided Gene Delivery for Musculoskeletal Tissue Repair

Gene therapy is a promising strategy for musculoskeletal tissue repair and regeneration where local and sustained expression of proteins and/or therapeutic nucleic acids can be achieved. However, the musculoskeletal tissues present unique engineering and biological challenges as recipients of genetic vectors. Targeting specific cell populations, regulating expression in vivo, and overcoming the harsh environment of damaged tissue accompany the general concerns of safety and efficacy common to all applications of gene therapy. In this review, we will first summarize these challenges and then discuss how biomaterial carriers for genetic vectors can address these issues. Second, we will review how limitations specific to given vectors further motivate the utility of biomaterial carriers. Finally, we will discuss how these concepts have been combined with tissue engineering strategies and approaches to improve the delivery of these vectors for musculoskeletal tissue regeneration.

Move it or Lose it. Is it Reasonable for Older Adults with Osteoarthritis to Continue to Use Paracetamol in Order to Maintain Physical Activity?

Osteoarthritis is a common progressive disease in older adults, and those affected often have impaired physical function, co-existing disease states, and reduced quality of life. In patients with osteoarthritis, pain is reported as a primary cause of mobility limitation, and guidelines recommend a mix of pharmacologic and non-pharmacologic strategies for pain management. The benefits of exercise in the management of osteoarthritis are well established; however, pain appears to be the biggest barrier to patients engaging in, and adhering to, physical activity programs. Attitudes towards the use of pain medications differ widely, and lack of efficacy or fear of side effects may lead to sub-therapeutic dosing. Furthermore, a recent review suggesting that short-term paracetamol use is ineffective for osteoarthritis has added to the confusion. This narrative review investigates limitations of current medications, summarizes patient attitudes toward the use of analgesics for osteoarthritis pain (with a focus on paracetamol), and explores the uptake of physical activity for osteoarthritis management. Evidence suggests that, despite clear guidelines, symptoms of osteoarthritis generally remain poorly managed. More research is required to investigate clinical outcomes in patients with osteoarthritis through optimized medication plans to better understand whether longer-term analgesic use in conjunction with physical activity can assist patients to overcome mobility limitations.

Modifiable lifestyle factors are associated with lower pain levels in adults with knee osteoarthritis

Pain is the most important osteoarthritis (OA) symptom; however, it is poorly understood and markers of disease severity cannot explain pain variability. With no cure for OA, the authors recognized the need to identify modifiable factors to decrease pain and increase physical function. This study examined factors that characterize OA patients experiencing different levels of pain and investigated the relationships among these factors and OA pain.

BACKGROUND:

With no cure or effective treatments for osteoarthritis (OA), the need to identify modifiable factors to decrease pain and increase physical function is well recognized.

OBJECTIVE:

To examine factors that characterize OA patients at different levels of pain, and to investigate the relationships among these factors and pain.

METHODS:

Details of OA characteristics and lifestyle factors were collected from interviews with healthy adults with knee OA (n=197). The Western Ontario and McMaster Universities Osteoarthritis Index was used to assess pain. Factors were summarized across three pain score categories, and χ² and Kruskal-Wallis tests were used to examine differences. Multiple linear regression analysis using a stepwise selection procedure was used to examine associations between lifestyle factors and pain.

RESULTS:

Multiple linear regression analysis indicated that pain was significantly higher with the use of OA medications and higher body mass index category, and significantly lower with the use of supplements and meeting physical activity guidelines (≥150 min/week). Stiffness and physical function scores, bilateral knee OA, body mass index category and OA medication use were significantly higher with increasing pain, whereas self-reported health, servings of fruit, supplement use and meeting physical activity guidelines significantly lower. No significant differences across pain categories were found for sex, age, number of diseases, duration of OA, ever smoked, alcoholic drinks/week, over-the-counter pain medication use, OA supplement use, physical therapy use, servings of vegetables or minutes walked/week.

CONCLUSIONS:

Healthy weight maintenance, exercise for at least 150 min/week and appropriate use of medications and supplements represent important modifiable factors related to lower knee OA pain.

A discrete-choice experiment of United Kingdom patients' willingness to risk adverse events for improved function and pain control in osteoarthritis

OBJECTIVE

To assess patient preferences for treatment-related benefits and risks associated with the use of nonsteroidal anti-inflammatory drugs (NSAIDs) in the management of osteoarthritis (OA).

DESIGN

Using a chronic-illness panel in the United Kingdom, patients 45 years or older with a self-reported diagnosis of OA were eligible to participate in the study. Patient preferences were assessed using a discrete-choice experiment that compared hypothetical treatment profiles of benefits and risks consistent with NSAID use. Benefit outcomes (ambulatory pain, resting pain, stiffness, and difficulty doing daily activities) were presented on a 0-to-100 mm scale. Risk outcomes (bleeding ulcer, stroke, and myocardial infarction [MI]) were expressed as probabilities over a fixed time period. Each patient answered 10 choice tasks comparing different treatment profiles. Preference weights were estimated using a random-parameters logit model.

RESULTS

Final sample included 294 patients. Patients ranked reductions in ambulatory pain and difficulty doing daily activities (both: 6.32; 95% confidence interval [CI]: 5.0-7.6) as the most important benefit outcomes, followed by reductions in resting pain (2.80; 95% CI: 1.8-3.8) and stiffness (2.65; 95% CI: 0.9-4.4). Incremental changes (3%) in the risk of MI or stroke were assessed as the most important risk outcomes (10.00; 95% CI: 8.2-11.8; and 8.90; 95% CI: 7.3-10.5, respectively).

CONCLUSION

Patients ranked ambulatory pain as a more important benefit than resting pain; likely due to its impact on ability to do daily activities. For a 25-mm reduction, patients were willing to accept four times the risk of MI in ambulatory pain vs resting pain.

Factors predicting older adults' use of exercise and acetaminophen for osteoarthritis pain

PURPOSE

To identify predictors of older adults' use of exercise and/or acetaminophen, and avoidance of nonsteroidal anti-inflammatory drugs (NSAIDs) to treat their osteoarthritis pain.

DATA SOURCES

Data were analyzed from 457 adults aged 60 and older with moderate or greater osteoarthritis pain intensity who responded to the Brief Pain Inventory between 2006 and 2007. The following predictors were entered into a logistic regression to predict use of exercise and/or acetaminophen and nonuse of NSAIDs: age, gender, ethnicity, race, education, arthritis treatment by a practitioner, pain treatment by a practitioner, pain intensity, functional interference from the pain, and percent of pain relief from current treatments.

CONCLUSIONS

A total of 213 (46.6%) reported using exercise and/or acetaminophen and did not report using NSAIDs. Older adults reporting arthritis treatment by a practitioner were 2.2 (confidence interval 1.08-4.59) more likely to use recommended arthritis pain treatment, p < .03. Only 3-4% of the variance for use of recommended pain management treatment was explained by the predictors.

IMPLICATIONS FOR PRACTICE

Results underscore the importance of guidance by practitioners who are knowledgeable about safe osteoarthritis pain management for older adults.

Osteoarthritis, osteoporosis, and exercise

With the aging of the work force, occupational health nurses must prepare for encounters with clients who are challenged by osteoarthritis or osteoporosis. Clients should be encouraged to exercise safely to promote functioning at home and work. This article reviews recent literature on the benefits of exercise for workers with osteoarthritis, osteoporosis, or both.

Racial differences in symptom management approaches among persons with radiographic knee osteoarthritis

Background

The extent to which racial differences exist in use of treatments for osteoarthritis (OA) is debatable. The purpose of this study was to describe the differences between African Americans (AA) and Caucasian Americans (CA) in using treatment approaches to manage symptoms among individuals with radiographic-confirmed knee OA.

Methods

A cross-sectional study was conducted. Using data from the Osteoarthritis Initiative, we identified 508 AA and 2,075 CA with radiographic tibiofemoral OA in at least one knee. Trained interviewers asked questions relating to current OA treatments including seven CAM therapy categories—alternative medical systems, mind-body interventions, manipulation and body-based methods, energy therapies, and three types of biologically based therapies, as well as conventional medications. We categorized participants as: conventional medication only users, CAM only users, users of both and users of neither. Multinomial logistic regression models adjusting for sociodemographics and clinical/functional factors provided estimates of the association between race and treatment use.

Results

Overall, 16.5% of AA and 24.2% of CA exclusively used CAM to treat OA, 25.0% of AA and 23.8% of CA used CAM in conjunction with conventional medications, and 24.8% of AA and 14.6% of CA exclusively used conventional medications. After control for sociodemographic and clinical factors, AA were less likely than CA to use CAM therapies alone (adjusted odds ratio (OR) of using CAM alone relative to no CAM or conventional treatments: 0.68, 95% confidence interval (CI): 0.48–0.96) or with conventional medications (adjusted OR relative to no CAM or conventional treatments: 0.59, 95%CI: 0.42–0.83). However, no differences in use of conventional medications alone were observed after adjustment of covariates.

Conclusion

CAM use is common among people with knee OA, but is less likely to be used by AA relative to CA. For effective CAM therapies, targeted outreach to underserved populations including education about benefits of various CAM treatments and providing accessible care may attenuate observed disparities in effective CAM use by race.

The impact of nurse prescribing on patients with osteoarthritis

Osteoarthritis (OA) is now considered one of the ten most disabling diseases in developed countries and it is estimated that worldwide, 18% of women and 9.6% of men aged over 60, suffer from OA. It is, therefore, vital to take into consideration the demographics of this disorder, including the health needs of this age group and associated problems, such as reduced mobility or immobility and the inability to perform everyday tasks associated with chronic pain. Older patients, however, are sometimes able to accept their condition and adopt a positive outlook towards their OA as a coping strategy. This association with and acceptance of pain by the patient as a normal part of the ageing process may compromise the patient's ability to undertake activities of daily living and impact their psychological wellbeing.

Effective management strategies for osteoarthritis

Osteoarthritis (OA) is a chronic disease which affects a significant number of people during working life and retirement. The principle symptoms of OA are pain, stiffness, and potentially reduced movement and function of the affected joint. In severe OA the ability to engage in work or social activity may be restricted and as a result, the health-related quality of life of the patient may be affected. There are a variety of approaches which can be implemented to manage symptoms, including the use of orthoses, exercise programmes or in severe cases, arthroplasty. It is important that emphasis is placed on patient empowerment and shared decision-making with regard to managing symptoms and preserving or improving function or the affected joint(s).

Hispanic older adults' osteoarthritis pain communication

Better understanding of how Hispanic older adults describe their chronic pain might suggest ways to support Hispanic older adults to talk about important pain information with their practitioner. The study aim was to describe how Hispanic older adults communicate pain information, including the amount of pain information and communication processes employed. A secondary analysis with a descriptive design was used. The data were from a larger primary study that tested the effect of practitioner pain question phrasing on the amount of pain information described by older adults with osteoarthritis pain. The sample for this secondary analysis was composed of the 24 Hispanic older adults with chronic osteoarthritis pain. In the primary study older adults watched and orally responded to a videotape of a practitioner asking about their pain. Pain content from the patient responses was content analyzed by two independent raters. Communication processes were also content analyzed by two independent raters using a priori criteria from communication accommodation theory (clarity, syntax, complexity, explicitness, and staying on topic). Participants described a mean of 5.5 (SD 3.39) items of pain information. The majority stayed on topic, and one-half spoke clearly and explicitly. Hispanic older adults with osteoarthritis pain concisely describe clinically important pain information when given the opportunity to do so.
