Chronic Pain in the Elderly: Mechanisms and Perspectives

Does Weather Have an Influence on Pain in Patients With Arthroplasty?

BACKGROUND

Patients undergoing total knee arthroplasty (TKA) and total hip arthroplasty (THA) often report fluctuations in pain levels associated with weather conditions. Despite common clinical observations, the literature remains inconclusive. This study aimed to evaluate the correlation between postoperative pain scores and weather parameters, considering demographic and comorbidity factors.

METHODS

A retrospective chart review was conducted on 558 patients who underwent TKA or THA between January 1, 2020 and December 31, 2023. Patients without significant comorbidities affecting surgical outcomes were included. Postoperative pain scores recorded using a numerical rating scale were correlated with historical weather data (temperature, barometric pressure, humidity) and compared to the entire group (both TKA and THA) and to subgroups (TKA or THA).

RESULTS

The mean pain score reported was 3.87. Weather parameters, including temperature and barometric pressure, did not yield significant results with pain scores. Analysis revealed a significant negative correlation between age and pain scores (r = -19 0.293, p < 0.001), indicating that older patients reported lower pain levels. Body mass index (BMI) was positively correlated with pain scores (p < 0.05), while sex and race/ethnicity showed no significant associations (p > 0.05). Notably, mental health diagnoses significantly influenced pain ratings (p < 0.05).

CONCLUSIONS

This study found no significant relationship between postoperative pain and weather parameters in patients who underwent TKA/THA, challenging common assumptions that weather significantly influences pain perception. However, age, BMI, and mental health were identified as significant factors affecting postoperative pain experiences. These findings underscore the need for personalized pain management strategies that account for individual patient characteristics.

Chronic musculoskeletal pain and its relationship with cognitive function in older adults: A systematic review and meta-analysis

BACKGROUND

The relationship between chronic musculoskeletal pain and cognitive function in older adults remains unclear. This study aimed to investigate whether the cognitive function of older adults with chronic musculoskeletal pain differs from asymptomatic older adults.

METHODS

Four databases (PubMed, Science Direct, Web of Science, and Scopus) were searched. Two researchers independently reviewed the references against the eligibility criteria and performed the quality assessment of included studies using The National Institutes of Health (NIH) - Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

RESULTS

A total of 8484 references were found and ten articles, published between 2006 and 2021, were included. Only one study was classified as being of good quality, the remaining were of fair quality. Independent meta-analysis were performed for global cognition and specific cognitive domains (language, attention/orientation, executive function, memory, processing speed, and visuospatial skills). Differences between older adults with and without chronic musculoskeletal pain were found for the domains of general cognition (k = 10; d = -0.20; 95% CI = -0.38, -0.03; z = -2.25, p = 0.03) and language (k = 8; d =  -0.16; 95% CI = -0.28, -0.05; z = -2.72, p = 0.006), with very low certainty of evidence.

CONCLUSION

Overall, and considering the very low certainty of evidence for both global cognition and specific cognitive domains, we are uncertain about whether cognitive function differs between older adults with and without chronic musculoskeletal pain. Further research is needed comparing cognitive performance between older adults with and without chronic musculoskeletal pain, on the long-term impact of pain on cognitive functioning, and on the mechanisms underlying this potential relationship.

A network analysis of changing pain cooccurrence in older adults findings from the second wave of the COPERNICUS study

Over one-third of patients with chronic pain report pain at multiple anatomical sites. The current study examined the co-localization of pain and its intensity over a 2-year follow-up period. Kendall rank correlation coefficient (denoted as tau) was applied for the co-occurrence of pain in specific locations. Individuals over the age of 60 years were recruited from the general population in Poland (N = 205, 60-88 years old). The lumbar spine was the most frequently occurring site for chronic pain, present in 31% of individuals at baseline and in 38% after 2 years. The number of pain sites did not change over 2 years (p = 0.53). An increase of co-occurrence between anatomical sites for pain was noted after 2 years. Cervical spine pain co-occurred with pain in the thoracic spine (tau = 0.31), lumbar spine (tau = 0.45), chest (tau = 0.18), hips (tau = 0.17), legs (tau = 0.18), knee(s) (tau = 0.31), and feet (tau = 0.17). The observed increase in pain co-occurrence over 2 years suggests the need for modified approaches to pain treatment in older adults.

System-based pain groups are uniquely associated with sociodemographic and psychiatric correlates among those with posttraumatic stress disorder (PTSD)

OBJECTIVE

Chronic pain is a prevalent comorbidity among those with posttraumatic stress disorder (PTSD). Chronic pain can be divided into specific pain (i.e., involving a single body system) and complex pain (i.e., involving multiple body systems). We explored sociodemographic and psychiatric differences between pain groups among those with PTSD.

METHOD

Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III, N = 36,309). Pain groups were determined through health professional confirmed self-report of chronic pain conditions within three body systems (musculoskeletal, nerve or digestive conditions). Psychiatric conditions were identified with the Alcohol Use Disorder and Associated Disabilities Interview Schedule for DSM-5; suicide attempts were assessed via self-report.

RESULTS

Among our PTSD sub-sample (n = 1779; 4.7%), 53.9% had no conditions, 25.6% endorsed specific pain, and 19.1% endorsed complex pain. Multinomial logistic regressions revealed increased odds of certain sociodemographic correlates (e.g., older age) common to both pain groups when compared to those with PTSD alone, as well as decreased odds (e.g., being non-White) unique to those with complex pain. Multivariable logistic regressions revealed both specific pain and complex pain were associated with increased odds of any lifetime personality disorder relative to the no pain group (AOR = 1.56 and 2.38, respectively). Complex pain was uniquely associated with increased odds of any past-year anxiety disorder, past-year tobacco use disorder, and lifetime suicide attempts (AOR range = 1.46-1.69) relative to PTSD alone.

CONCLUSION

Findings indicate that those with PTSD and pain conditions impacting multiple body systems represent a particularly vulnerable group.

The Combined Relationship of Prescription Drug Monitoring Program Enactment and Medical Cannabis Laws with Chronic Pain-Related Healthcare Visits

BACKGROUND

U.S. state electronic prescription drug monitoring programs (PDMPs) are associated with reduced opioid dispensing among people with chronic pain and may impact use of other chronic pain treatments. In states with medical cannabis laws (MCLs), patients can use cannabis for chronic pain management, reducing their need for chronic-pain related treatment visits and moderating effects of PDMP laws.

OBJECTIVE

Given high rates of chronic pain among Medicaid enrollees, we examined associations between PDMP enactment in the presence or absence of MCL on chronic pain-related outpatient and emergency department (ED) visits.

DESIGN

We created annual cohorts of Medicaid enrollees with chronic pain diagnoses using national Medicaid claims data from 2002-2013 and 2016. Negative binomial hurdle models produced adjusted odds ratios (aOR) for the likelihood of any chronic pain-related outpatient or ED visit and incident rate ratios (IRR) for the rate of visits among patients with ≥ 1 visit.

PARTICIPANTS

Medicaid enrollees aged 18-64 years with chronic pain (N = 4,878,462).

MAIN MEASURES

A 3-level state-year variable with the following categories: 1) no PDMP, 2) PDMP enactment in the absence of MCL, or 3) PDMP enactment in the presence of MCL. Healthcare codes for chronic pain-related outpatient and ED visits each year.

KEY RESULTS

The sample was primarily female (67.2%), non-Hispanic White (51.2%), and ages 40-55 years (37.2%). Compared to no-PDMP states, PDMP enactment in the absence of MCL was not associated with chronic pain-related outpatient visits but PDMP enactment in the presence of MCL was associated with lower odds of chronic pain-related outpatient visits (aOR = 0.81, 95% CI:0.71-0.92). PDMP enactment was not associated with ED visits, irrespective of MCL.

CONCLUSIONS

During a period of PDMP and MCL expansion, our findings suggest treatment shifts for persons with chronic pain away from outpatient settings, potentially related to increased use of cannabis for chronic pain management.

Chronic Postsurgical Pain Raises Risk of Dementia

PURPOSE

This study aimed to investigate the association between chronic postsurgical pain (CPSP) and the risk of dementia, addressing a significant gap in the existing literature and highlighting potential implications for clinical practice and public health.

PATIENTS AND METHODS

Utilising data from Taiwan's National Health Insurance Research Database, a propensity score-matched cohort study was conducted involving 142,682 patients who underwent major surgery between 2004 and 2018. CPSP was defined as prolonged analgesic use post-surgery, and dementia diagnosis was tracked until December 31, 2022. Multivariable Cox regression models were employed to calculate adjusted hazard ratios (aHRs) for dementia risk in CPSP versus non-CPSP groups.

RESULTS

Before propensity score matching, the CPSP cohort (n = 37,438) exhibited a higher risk of dementia, with aHRs of 1.35 (95% CI: 1.30-1.40). After matching, the aHR remained elevated at 1.31 (95% CI: 1.26-1.37), indicating a significant association between CPSP and dementia risk. Subgroup analysis confirmed this association across various demographic and clinical factors, with sensitivity analysis reinforcing the robustness of the findings.

CONCLUSION

This study establishes CPSP as an independent predictor of dementia risk, highlighting the importance of postoperative pain management in mitigating long-term cognitive outcomes. Approximately 30% of dementia risk post-CPSP presents an opportunity for risk reduction through effective CPSP management strategies, emphasising the need for targeted interventions to address this critical healthcare issue.

SIGNIFICANCE

This study provides compelling evidence that chronic postsurgical pain (CPSP) significantly increases the risk of dementia, highlighting a critical and previously underexplored connection between postoperative pain and long-term cognitive decline. By establishing CPSP as an independent predictor of dementia, our findings underscore the importance of effective pain management strategies in surgical patients, particularly to mitigate the heightened risk of dementia and improve long-term outcomes.

New generation capsaicin-diclofenac containing, silicon-based transdermal patch provides prolonged analgesic effect in acute and chronic pain models

OBJECTIVE

Pain is one of the major public health burdens worldwide, however, conventional analgesics are often ineffective. Capsaicin-the active compound of Capsicum species, being responsible for their pungency-has been part of traditional medicine long ago. Capsaicin is a natural agonist of the Transient Receptor Potential Vanilloid 1 receptor-localized on capsaicin-sensitive sensory neurons and strongly involved in pain transmission-, and has been in focus of analgesic drug research for many years. In this study, we aimed to develop a sustained release transdermal patch (transdermal therapeutic system, TTS) combining the advantages of low-concentration capsaicin and diclofenac embedded in an innovative structure, as well as to perform complex preclinical investigations of its analgesic effect.

METHODS

Drug delivery properties of the TTS were investigated with Franz cell and flow-through cell tests. Analgesic effect of the TTS was examined in in vivo models of acute postoperative and inflammatory, chronic neuropathic and osteoarthritic pain.

RESULTS

Modified silicone polymer matrix-based TTS containing low-concentration capsaicin and diclofenac has been developed, releasing both compounds according to zero-order kinetics. Moreover, capsaicin and diclofenac facilitated the liberation of each other. Combined TTS significantly reduced acute postoperative and inflammatory pain, as well as chronic neuropathic and osteoarthritic pain. Interestingly, in acute postoperative and chronic osteoarthritic pain, capsaicin prolonged and potentiated the pain-relieving effect of diclofenac.

CONCLUSIONS

New generation combined low-concentration capsaicin-diclofenac containing TTS can be an effective therapeutic tool in acute and chronic pain states involving neuropathic and inflammatory components.

Effects of aging on experimentally induced pain perception during a distraction task

To investigate the effects of psychological (anxiety, depression, pain catastrophizing) aspects, pain sensitivity, cognitive performance and executive functions, on pain perception during a distraction task in an acute pain laboratory in young and elderly adults. Twenty-six young (age: 20.0 ± 1.6 years) and thirty-three elderly (age: 68.0 ± 3.8 years) adults completed four self-reported questionnaires (Hospital Anxiety and Depression Scale-HADS, Pain Anxiety Symptoms Scale-20-PASS/20, Pain Catastrophizing Scale-PCS, and Pittsburgh Sleep Quality Index-PSQI), pressure pain thresholds (PPTs), a battery of executive functions (working memory, cognitive flexibility, mental inhibition), and attention levels before performing two distraction tasks (1-back, 2-back). Pain was experimentally induced with a thermal stimulus applied at the non-dominant forearm to provoke moderate pain (70/100 points) before and during the distraction tasks. Age (young, elderly), psychological and psychophysical variables, and neurocognitive test performance levels (low, medium, high) were included in separate ANCOVAs to compare pain intensity at baseline and during distraction tasks. All ANOVAs revealed a main effect of distraction task, indicating that perceived pain intensity scores were lower during both distraction tasks (p < 0.001) compared to baseline. Overall, there was no significant effect of age on perceived pain intensity after distraction tasks, except for an interaction effect between the distraction task and age group depending on PPTs levels (F [2,49] = 3.7, p = 0.03). Elderly adults (with higher PPTs) reported lower perceived pain intensity during both distraction tasks compared to younger adults (lower PPTs). This study found that the hypoalgesic effect of a distraction task is not directly associated with age or neurocognitive function and attention levels in pain-free subjects, but it was related with higher PPTs (lower pressure pain hyperalgesia).

NO Pain! No Cancer? The Crosstalk Between Nociception, ROS, and Cancer Development

Transient receptor potential (TRP) channels, particularly those involved in nociception (nociceptive TRP channels), are implicated in both pain and cancer development. Activation of these channels by diverse stimuli triggers calcium influx, leading to mitochondrial oxidative stress and reactive oxygen species (ROS) accumulation. This ROS production contributes to both nociceptive signaling (causing pain) and aging processes, including genomic instability, a key driver of carcinogenesis. Although a direct causal link between pain and cancer onset remains elusive, the shared involvement of nociceptive TRP channels strongly suggests a correlation. This opinion article proposes targeting the crosstalk between nociceptive TRP channels and ROS as a promising therapeutic strategy to mitigate cancer and cancer-associated pain simultaneously. While further research is needed to definitively establish a causal relationship between pain and cancer risk, the available evidence suggests that inhibiting this pathway may offer significant benefits for both cancer prevention and treatment.

Building Consensus on the Relevant Criteria to Screen for Depressive Symptoms Among Near-Centenarians and Centenarians: Modified e-Delphi Study

BACKGROUND

The number of centenarians worldwide is expected to increase dramatically, reaching 3.4 million by 2050 and >25 million by 2100. Despite these projections, depression remains a prevalent yet underdiagnosed and undertreated condition among this population that carries significant health risks.

OBJECTIVE

This study aimed to identify and achieve consensus on the most representative signs and symptoms of depression in near-centenarians and centenarians (aged ≥95 years) through an e-Delphi study with an international and interdisciplinary panel of experts. Ultimately, the outcomes of this study might help create a screening instrument that is specifically designed for this unique population.

METHODS

A modified e-Delphi study was carried out to achieve expert consensus on depressive symptoms in near-centenarians and centenarians. A panel of 28 international experts was recruited. Consensus was defined as 70% agreement on the relevance of each item. Data were collected through a web-based questionnaire over 3 rounds. Experts rated 104 items that were divided into 24 dimensions and 80 criteria to identify the most representative signs and symptoms of depression in this age group.

RESULTS

The panel consisted of experts from various countries, including physicians with experience in old age psychiatry or geriatrics as well as nurses and psychologists. The response rate remained consistent over the rounds (20/28, 71% to 21/28, 75%). In total, 4 new dimensions and 8 new criteria were proposed by the experts, and consensus was reached on 86% (24/28) of the dimensions and 80% (70/88) of the criteria. The most consensual potentially relevant dimensions were lack of hope (21/21, 100%), loss of interest (27/28, 96%), lack of reactivity to pleasant events (27/28, 96%), depressed mood (26/28, 93%), and previous episodes of depression or diagnosed depression (19/21, 90%). In addition, the most consensual potentially relevant criteria were despondency, gloom, and despair (25/25, 100%); depressed (27/27, 100%); lack of reactivity to pleasant events or circumstances (28/28, 100%); suicidal ideation (28/28, 100%); suicide attempt(s) (28/28, 100%); ruminations (27/28, 96%); recurrent thoughts of death or suicide (27/28, 96%); feelings of worthlessness (25/26, 96%); critical life events (20/21, 95%); anhedonia (20/21, 95%); loss of interest in activities (26/28, 93%); loss of pleasure in activities (26/28, 93%); and sadness (24/26, 92%). Moreover, when assessing depression in very old age, the duration, number, frequency, and severity of signs and symptoms should also be considered, as evidenced by the high expert agreement.

CONCLUSIONS

The classification of most elements as relevant highlights the importance of a multidimensional approach for optimal depression screening among individuals of very old age. This study offers a first step toward improving depression assessment in near-centenarians and centenarians. The development of a more adapted screening tool could improve early detection and intervention, enhancing the quality of mental health care for this population.

Informal caregivers' burden and chronic pain in older adults: a dyadic study unveiling the correlation and its impact

BACKGROUND AND AIMS

Older adults' chronic pain care includes assisting with daily activities and exercise. But the informal caregivers have stated different challenges in the caring process. This study aims to explore the chronic pain situations of older adults, the burden of their informal caregivers, and the correlation between the severity of chronic pain in older adults and the level of burden experienced by their caregivers.

METHODS

A total of 150 older adults (mean age: 65.44) with chronic pain and 150 informal caregivers (mean age: 41.06) were recruited for this study. Older adults completed the brief pain inventory and pain self-efficacy questionnaire. Depression, anxiety, stress, and activities of daily living were assessed. Informal caregivers also completed the caregiver burden inventory.

RESULTS

150 informal caregivers completed the questionnaire. The mean caregiver burden score was 3.73, positively associated with pain conditions and emotional tolls in older adults.

CONCLUSION

The findings highlight the need for healthcare professionals to address the physical and emotional burdens experienced by informal caregivers. Healthcare professionals should investigate the caregiver burden. Comprehensive support strategies should be developed to enhance the well-being of both older adults and their caregivers, ultimately improving pain management and quality of life.

Assessing the fidelity of the "photo-with-movement program" (PMP) for community-dwelling older adults with pain: A randomized controlled trial

PURPOSE

To measure intervention fidelity of the Photo-with-Movement Program (PMP) and to report the findings of the program.

METHODS

This study was a two-arm, pilot randomized controlled trial of the PMP. An intervention fidelity checklist and semi-structured interviews were utilize to evaluate the fidelity of the PMP. Twenty-four older adults and informal caregiver dyads enrolled in the study, with 12 dyads in the experimental group and another 12 in the control group. The PMP integrated visual stimulation, physical exercise, and digital-based activity to deliver a comprehensive, non-pharmacological pain relief syllabus to the participants in the experimental group. The control group received pain management pamphlets. The data collected were analyzed using SPSS to compare the outcomes between the experimental and control groups.

RESULTS

The PMP led to significant findings on reducing pain intensity and high scores on intervention fidelity. Participants showed great acceptance of this delivery format.

CONCLUSIONS

This study revealed the fidelity and effectiveness of a multimodal non-pharmacological intervention, suggesting that it could be used for pain management and caregiving.

Behavioral assessment to evaluate the analgesic and anti-inflammatory effects of Fagonia bruguieri var. laxa boiss by targeting pro-inflammatory cytokines and prostaglandin pathways

ETHNOPHARMACOLOGICAL RELEVANCE

Fagonia bruguieri var. laxa Boiss., also known as Dhamansa or Dhamaran, is a well-known xerophyte traditionally used for managing pain, inflammation, fever, and related disease conditions.

AIMS OF THE STUDY

This study was designed to assess the chemical profile of hydromethanolic (70%) extract of F. bruguieri (HMEFB), its analgesic, anti-inflammatory, and antipyretic properties, and the possible mechanisms involved, using rats and mice as experimental animals.

MATERIALS AND METHODS

HMEFB was subjected to chemical profiling using polyphenolic quantification and HPLC analysis. An oral toxicity test in mice assessed the extract for safety and toxicity. The central analgesic effect of HMEFB was evaluated in rats subjected to hot plate and tail immersion tests. Formalin and capsaicin tests were carried out to further support the evidence of analgesic action. The test of acetic acid-induced writhing was performed in mice to estimate the peripheral analgesic potential. The anti-inflammatory effect was studied by the carrageenan-induced paw edema model, while, an antipyretic study was conducted following the yeast-induced pyrexia method. Moreover, inflammatory cytokines and prostaglandins were estimated in the blood samples of animals from various groups to assess the possible mechanism involved in the anti-inflammatory potential of the extract.

RESULTS

The chemical profiling of HMEFB revealed the presence of functionally important polyphenols. The oral toxicity test revealed the safety up to the dose of 5 mg/kg b.w. The extract was found to have significant analgesic activity at the doses of 300 and 500 mg/kg in hot plate, tail immersion, capsaicin, and formalin tests. Furthermore, HMEFB significantly reversed the acetic acid-induced writhing compared to the control group. Similarly, HMEFB showed a dose-dependent effect against carrageenan-induced paw edema. While, in the yeast-induced pyrexia model, HMEFB showed a decrease in rectal temperature at 300 and 500 mg/kg. The extract significantly modulated the levels of pro-inflammatory cytokines and prostaglandins in different treated groups.

CONCLUSION

The results reinforce the folkloric use of F. bruguieri in pain and inflammation by verifying its analgesic and anti-inflammatory activities both via central and peripheral anti-nociceptive mechanisms which authenticate the use of this plant species as a suitable alternative for the alleviation of pain and inflammatory disorders.

The relationship between pain, sleep quality, and care dependency in older adults living in a long-term care facility

BACKGROUND

Due to the frequency of pain, sleep disorders and the complexity of their associated factors, the diagnosis of these disorders may be of great importance in identifying factors linked to care dependency in older people staying in long-term care facilities. The aim of the study was to investigate the relationship between pain, sleep quality, and care dependency in older adults living in a long-term care facility.

METHODS

The study was conducted among older people staying in a long-term care facility between October 2022 and September 2023. The study used a survey questionnaire including questions about demographic and social characteristics, clinical condition and the following scales: ADL, IADL, GSD-15, GPM-24, CDS, PSQI.

RESULTS

The analysis showed a statistically significant relationship between the deterioration of sleep quality by 1 unit and: an increase in the level of pain (B = 0.68; SE = 0.17; 95% CI [0.38; 1.10]), dependency in ADL (B = -0.09; SE = 0.04; 95% CI [-0.17; -0.02]), feeling depressed (B = 0.18; SE = 0.06; 95% CI [0 0.06, 0.31]) and care dependency (B = -0.78, SE = 0.24, 95% CI [-1.25, -0.31]). A statistically significant effect was noted between: pain level (B = -0.18; SE = 0.06; 95% CI [-0.30; -0.05], dependency in ADL (B = 1.98; SE = 0.35; 95% CI [1.28; 2.68]), instrumental activities of daily living (B = 1.86; SE = 0.28; 95% CI [1.30; 2.42]], feelings of depression (B = -0.96; SE = 0.17; 95% CI [-1.30; -0.62]) and care dependency.

CONCLUSIONS

The study is a valuable addition to research showing a strong link between pain, sleep quality and care dependency. The results support the need for a holistic approach in assessing pain, sleep quality, care dependency in older adults living in a long-term care facility.

Recurrent pain in older age: A cross-sectional network analysis of biopsychosocial-existential interactions

OBJECTIVE

Chronic pain is a prevalent condition in older adults, associated with substantial distress. For many older people, chronic pain interferes with their daily life which is reflected in various life domains. This study aimed to investigate whether interactions among self-reported indicators of biological, psychological, social, and existential life domains differ for older adults with no pain, with non-interfering pain, and with interfering pain.

METHOD

The study was based on the cross-sectional 65+ and Safe Study data (N = 622; age range 64-106 years; 60.6 % women). Network analysis was used to assess the inter-variable associations for older adults reporting no pain, non-interfering pain, and interfering pain separately. Network visualization and centrality tests were performed. Permutation-based analyses were conducted to investigate the connections among variables in three subgroups.

RESULTS

We identified a structural difference between the networks of older adults with no pain and interfering pain, suggesting differences in connectivity among the life domains. The strength centrality metrics showed the central role of presence of meaning in the networks of older adults with no pain and with non-interfering pain, while for older adults with interfering pain, anxiety appeared to be dominant.

CONCLUSION

The findings illuminated that anxiety regulation and meaning-enhancement are potentially important intervention targets for older adults with recurrent pain. Overall, the study highlighted the value of a holistic biopsychosocial-existential approach for understanding and managing pain in older adults.

Gonadal Hormone Changes with Aging and Their Impact on Chronic Pain

Chronic pain, pain that lasts beyond three months, is a common finding in the elderly. It is often due to musculoskeletal conditions but can be precipitated by other factors as well. While physiological systems decline with aging, chronic pain is influenced by changes in hormone profiles as men and women enter into andropause and menopause, respectively. Research on gonadal hormones is limited, especially when it comes to their relationship with chronic pain. Women tend to experience less pain with aging compared to their premenopausal years, and this is partially explained by the fact that estrogen enhances pain sensitivity and its decline during menopause decreases it. However, hormone replacement therapy (HRT) seems to increase pain tolerance post-menopause. There is some evidence that testosterone plays a protective factor in pain perception. Men on the other hand, have higher pain tolerance as testosterone is considered to be a protective factor. With aging and decreasing testosterone, older men tend to be less tolerant to pain. This paper explores how hormonal changes with aging impact pain perception in both men and women, highlighting several pain conditions influenced by hormones. Although research remains limited, the potential of HRT as a treatment for common pain conditions is examined.

Prevalence and location of myofascial trigger points in dogs with osteoarthritis

Introduction

This study was designed to determine the prevalence of myofascial pain and the location of myofascial trigger points (MTPs) in dogs with osteoarthritis.

Methods

Thirty-five dogs were selected and examined for the presence of MTPs using palpation. Assessments were performed independently by two examiners. Correlations between age, MTP number and location, and the site of osteoarthritis were also investigated.

Results and discussion

Thirty out of 35 dogs (86%) had at least one MTP and only 5 (14%) had none. A total of 177 MTPs were identified in dogs in this sample. The prevalence of MTPs was higher in the longissimus thoracicae (40% and 43%; left and right side respectively), followed by the quadriceps femoris (40% and 31%), longissimus lumborum (20% and 23%), gluteus medius and deltoid muscles (14%; left side only), and the pectineus muscle (11%; right side only). The number of osteoarthritic joints was not correlated with the number of MTPs or age. However, age was positively correlated with the number of muscles affected by MTPs. Correlations between the presence of MTPs in muscles surrounding and the affected joints were also lacking.

Conclusion

The prevalence of MTPs in dogs with osteoarthritis is high. Myofascial TPs are positively correlated with age in these patients. The subjective nature of palpation is a major limitation in myofascial pain assessment. Appropriate training and use of standardized diagnostic criteria are recommended.

Barriers and facilitators to effective pain management in elderly Arab patients: a nursing perspective through a qualitative study

BACKGROUND

Effective pain management in elderly patients is crucial for quality of life, yet cultural and institutional factors can significantly impact care delivery, particularly in Arab healthcare settings.

AIM

To explore the barriers and facilitators to effective pain management in elderly Arab patients from the perspective of nurses.

METHODS

A qualitative descriptive study was conducted with 12 registered nurses from various departments at Tanta University Hospitals, Egypt. Data were collected through semi-structured interviews, observations, and document analysis. Content analysis was used to identify themes and subthemes.

RESULTS

Five main themes emerged: (1) Cultural Barriers to Pain Expression, including stoicism and religious beliefs; (2) Institutional Barriers to Pain Management, such as resource limitations and time constraints; (3) Facilitators to Effective Pain Management, including family support and nurse adaptability; (4) Interdisciplinary Collaboration, emphasizing teamwork and education; and (5) Emotional and Professional Rewards for nurses. Cultural factors often led to underreporting of pain, while institutional constraints hindered thorough assessments. Nurse adaptability and family support, when present, facilitated better pain management.

CONCLUSION

The study reveals complex interplay between cultural, institutional, and professional factors influencing pain management in elderly Arab patients. Findings suggest the need for culturally sensitive pain assessment tools, enhanced nurse education in pain management, and policies promoting family-centered care and interdisciplinary collaboration.

IMPLICATIONS

Results can inform the development of culturally appropriate pain management strategies and policies in Arab healthcare settings, potentially improving care quality for elderly patients.

Frailty as a mediator of postoperative delirium in older adults undergoing orthopedic surgery: A causal mediation analysis

Background

Postoperative delirium has a high prevalence in hospitalized older adults. Frail older adults have an increased risk for developing it. Preoperative pain-a common symptom in older adults with orthopedic conditions-shows a connection with frailty through an inflammatory process. However, an association among preoperative pain, frailty, and postoperative delirium remains unexplored among older adults undergoing orthopedic surgery.

Objectives

To examine the magnitude, direction, and mediation effect of frailty on the association between preoperative pain and postoperative delirium among older adults undergoing orthopedic surgery.

Design

A secondary analysis of a prospective cohort study.

Setting and participants

A cohort of 200 older adults (60 years and older) who underwent major orthopedic surgery at a university hospital in Thailand was recruited for the study.

Methods

Participants responded to the Demographic and Health Information Form, the Reported Edmonton Frailty Scale-Thai version, and the Thai version of the 4 A's test. Analyses were conducted using a causal mediation analysis with 95 % confidence intervals.

Results

We found that 12.5 % of participants developed postoperative delirium. For the direct paths associated with postoperative delirium, statistically significant effects were observed for frailty, preoperative pain, and comorbidity. Considering frailty as a mediator of postoperative delirium, a significant positive indirect effect was identified from preoperative pain. Controlling for age and comorbidities, frailty mediated the association between preoperative pain and postoperative delirium in a statistically significant manner; the average direct effect was 0.014 (95 % confidence interval: 0.008-0.020), the average causal mediating effect was 0.002 (95 % confidence interval: 0.000-0.010), the total effects was 0.017 (95 % confidence interval: 0.010-0.020), and the probability mediation accounted for 14 % (95 % confidence interval: 0.031-0.300).

Conclusion

Integrating the concept of age-related decline and frailty assessment may offer opportunities to provide disease-specific care and strengthen precision perioperative care, which ultimately enhance quality of life in older adults undergoing orthopedic surgery.

Examining the Impact of Far-Infrared Technology on Quality of Life in Older Adults

The purpose of this study was to examine the effects of far-infrared (FIR) heat on quality of life (QOL) in older adults. Participants were assigned to either a convective heat group (CON) or a convective and FIR group. Participants received six, 30-min heat sessions over the course of three weeks. Pre- and post-assessments included physical measures such as range of motion, gait speed, Timed Up and Go, and hand grip strength. Standardized questionnaires were used to determine pain severity and its interference with daily life, and the impact pain had on overall QOL. Pain severity was significantly reduced (from 3.31 to 2.5, p < .05) in the FIR group from pre-to-post, and pain interference was significantly reduced (from 1.26 to 0.43, p < .05) in the CON group from pre-to-post testing. Findings suggest that heat therapy was successful in reducing pain over time.

Prevalence of and risk factors associated with chronic opioid use after traumatic injury: A historical cohort study using the Korean National Health Insurance Service sample cohort data

Chronic opioid use (COU) after traumatic injuries is a global health concern. COU after trauma delays recovery and increases the risk of long-term drug dependence. However, the population-prevalence and factors associated with COU after traumatic injury in South Korea remain unclear. We aimed to estimate the prevalence of COU and associated risk factors in patients after trauma in South Korea. A historical cohort study using the population-representative database including 1,103,405 South Korean subjects, patients admitted due to a newly diagnosed trauma (n = 65,444) or nontraumatic etiologies (n = 338,321) from January 1, 2003, to June 30, 2015, were analyzed. COU was defined as the prescription of opioid in the first 3 to 6 months from the index date. Prevalence of COU was summarized. A multivariable logistic regression analysis was conducted to investigate association of COU with traumatic injuries, accounting for a priori sociodemographic and clinical risk factors. A total of 13.5% and 12.6% of patients were found to be chronic opioid users in the trauma and the control group, respectively. The adjusted odds ratio (aOR) (95% CI) of COU in the injured compared to the noninjured was 1.13 (1.01 to 1.16), when controlling for age group, sex, calendar year, area of residence, previous opioid use, comorbidity, surgery during the index admission and intensive care unit care. Risk factors included being aged 65 to 74 years (aOR = 2.87; 95% CI = 2.73 to 3.01), aged ≥ 75 years (aOR = 2.48; 95% CI = 2.35 to 2.62), and history of previous opioid use (aOR = 3.27; 95% CI = 3.21 to 3.34) were the most significant risk factors of COU, independent of injury. COU was prevalent both in the injured and noninjured patients, with slightly increased risk of COU in those sustaining traumatic injury compared to those who were noninjured. Further stud y to address prevalent COU in South Korea is required to avoid opioid-related harms.

Pain relief survivorship: a comparison of Exactech Equinoxe anatomic and reverse total shoulder arthroplasty for primary osteoarthritis

BACKGROUND

Pain relief plays a major deterministic role when assessing postoperative patient satisfaction; however, whether anatomic total shoulder arthroplasty (aTSA) or reverse total shoulder arthroplasty (rTSA) provides the most durable pain relief has not been studied. The purpose of this study was to evaluate the durability of pain relief after aTSA compared with rTSA in patients undergoing surgery for rotator cuff-intact glenohumeral osteoarthritis (RCI-GHOA).

METHODS

A retrospective review of a multicenter shoulder arthroplasty database (Exactech Equinoxe) was performed. We included 1848 aTSAs and 1464 rTSAs performed for RCI-GHOA between 2007 and 2023. Pain after surgery was assessed postoperatively at 3 months, 6 months, and yearly thereafter. Average postoperative pain on a daily basis and pain at worst were compared between aTSA and rTSA up to 8 years postoperatively. Kaplan-Meier survivorship analysis for pain relief maintenance was performed to compare the maintenance of clinically relevant pain relief defined as pain scores that achieved the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS). Maintenance of favorable patient satisfaction over time was also evaluated. Multivariable cox regression was performed to determine whether the type of prosthesis (aTSA vs. rTSA) was independently associated with pain recurrence.

RESULTS

Maintenance of achievement of the MCID and SCB for both daily pain and pain at worst as well as favorable patient satisfaction was similar between aTSAs and rTSAs. However, aTSA had longer maintenance of average daily pain below the PASS compared with rTSA (P = .024). This was confirmed on multivariable cox regression analysis, which found that rTSAs had a 34% greater likelihood of recurrence of postoperative average daily pain exceeding the PASS (visual analog scale score rating 1/10) compared with aTSAs.

CONCLUSION

Patients who undergo either aTSA or rTSA for RCI-GHOA and achieve initial pain relief postoperatively can expect to maintain their clinically relevant pain improvement at similar rates up to 8 years postoperatively. However, recurrence of low levels of daily pain was significantly higher after rTSA.

Insights into Vincristine-Induced Peripheral Neuropathy in Aged Rats: Wallerian Degeneration, Oxidative Damage, and Alterations in ATPase Enzymes

This study aimed to elucidate vincristine (VCR)-induced peripheral neuropathy in aged rats, a poorly understood neurotoxicity. Both young and old Wistar rats were administered VCR (0.1 mg/kg, intraperitoneally (i.p.)) and compared to age-matched controls (0.9% saline; 10 mg/mL, i.p.). Mechanical (MN) and thermal nociceptive (TN) responses were assessed on days 0, 6, 11, and 17. Locomotor response, cognitive ability, and anxious-like behavior were evaluated on days 14, 15, and 16. Results showed MN and TN responses in both young and old VCR-exposed rats. In old rats, VCR exacerbated MN (on days 6, 11, and 17) and TN (on days 6 and 17) responses. VCR also induced cognitive impairments and anxiety-like behavior. Histological analysis revealed Wallerian degeneration in the spinal cords of VCR-exposed rats accompanied by macrophage migration. Furthermore, VCR increased Ca2+-ATPase activity while inhibiting Na+, K+-ATPase activity in young and old rats. VCR altered the homeostasis of Mg2+-ATPase activity. Lipid peroxidation and nitrite and nitrate levels increased in young and old rats exposed to VCR. This study provides valuable insights into VCR's mechanistic pathways in aged rats, emphasizing the need for further research in this area.

Examining pain, function, behavioral symptoms and associations with engagement in meaningful activity for residents with dementia in assisted living

OBJECTIVES

The purpose of this study was to examine factors associated with engagement in meaningful activity among residents with dementia in assisted living. We hypothesized that greater functional independence, less pain, and lower behavioral and psychological symptom severity would be associated with higher engagement in meaningful activity after controlling for residents' age, gender, comorbidities, and cognition. Understanding factors associated with engagement in meaningful activity can help to inform strategies for optimizing engagement among residents with dementia in assisted living.

METHOD

This descriptive study used baseline data from a randomized controlled trial, Meaningful Activity for Managing Behavioral Symptoms of Distress (MAC-4-BSD). Linear regression was used to examine factors associated with engagement in meaningful activity.

RESULTS

A total of 71 residents from 5 assisted living settings were included in the sample. Most participants were female (n = 52, 73%), White (n = 62, 87%), and mean age was 85 years old (SD = 8.2). Controlling for age, gender, comorbidities, and cognition, pain was significantly associated with engagement in meaningful activity (b= -2.09, p < 0.05). There were no associations found between function and behavioral symptoms with engagement in meaningful activity.

CONCLUSION

Findings from this study show that pain is a significant factor that is negatively associated with residents' engagement in meaningful activity. Ongoing research is needed to help improve pain management for residents with dementia in assisted living and support their engagement in meaningful activity.

to develop an information model on pain management in hospitalized aged people.

a Big Data retrospective and observational study guided by the Applied Healthcare Data Science Roadmap. The sample included all Electronic Health Records related to pain management in older adults aged at least 75 years old considered vulnerable in the institution and admitted to clinical and surgical units. Data science packages were used in Python ® for data analysis.

a total of 9,635 hospitalizations were found for 4,753 patients, with a mean age of 81 years old and 54% belonging to the female gender. The main reasons for hospitalization were diseases of the circulatory system (n=1,593; 28.6%), neoplasms (n=893; 16%) and diseases of the genitourinary system (n=508; 9.1%). A total of 60 attributes related to pain were identified and organized into groups: current pain, assessment instruments and characteristics, Nursing diagnosis, etiology of the Nursing diagnosis, interventions for relief, consultations to specialties and pain reassessment. The groups were classified into four large panels that constituted the information model.

the information model developed presented an overview of the healthcare reality of pain management in vulnerable aged people, supporting decision-making for pain management in this population segment.

PROGRESS: A patient-centered engagement infrastructure and multi-level approach to enrich diversity, equity, and inclusion in a national randomized online behavioral pain treatment study

Twenty percent of individuals experience chronic pain worldwide posing significant challenges to those living with it. Pain research is crucial for developing and characterizing effective strategies to reduce the burden of chronic pain. Traditional research approaches often yield homogeneous study samples that poorly generalize and have unknown applicability across diverse patient populations. The Pain Relief with Online Groups that Empower Skills-based Symptom Reduction (PROGRESS) study aims to address disparities in pain research engagement and patient outcomes through the intentional inclusion of people with varied backgrounds and experiences of pain, and through a multilevel design informed by diverse stakeholder recommendations. The composition of three advisory boards (Patient Engagement and Diversity Board, Local Patient Advisory Board, and the National Patient Advisory Panel) prioritized diversity in patient/expert advisor background, geographic location, race, and ethnicity. Our engagement approach aligns with the Foundational Expectations for Partnerships in Research by Patient-Centered Outcomes Research Institute (PCORI), which emphasizes diverse representation, early and ongoing engagement, dedicated funds for advisor compensation, collaborative decision making, meaningful participation, and continuous assessment. The first 24 months of study advisor engagement has yielded multiple recruitment strategies resulting in a study population enriched with a breadth of identities within PROGRESS (e.g., inclusive patient-facing materials). Lessons learned underscore the importance of investing time in building patient and stakeholder relationships, trust, and embracing diverse viewpoints amongst the study team. PROGRESS demonstrates the potential of diverse patient-centered engagement to support evidence-based outcomes and practices that are more inclusive, equitable, and representative of the broader population. PERSPECTIVE: The PROGRESS study demonstrates how diverse patient engagement and inclusive advisory boards enhance research outcomes. By aligning with PCORI standards and employing innovative recruitment strategies, it highlights the vital role of stakeholder relationships and diverse perspectives. Key lessons learned emphasize adaptive strategies and continuous feedback for advancing equitable pain research.

Assessing the Association of Pain Intensity Scales on Quality of Life in Elderly Patients with Chronic Pain: A Nursing Approach

BACKGROUND

Chronic pain is prevalent among the elderly and significantly affects their quality of life (QoL). Pain intensity scales are crucial tools in evaluating the severity of pain and tailoring management strategies. This study investigates the relationship between various pain intensity scales and QoL among elderly patients with chronic pain, highlighting the implications for nursing practice.

METHODS

A cross-sectional study was conducted with 150 elderly patients (aged 65 and above) in Riyadh, Saudi Arabia. Participants were assessed using the Numeric Rating Scale (NRS), Visual Analog Scale (VAS), and McGill Pain Questionnaire (MPQ) alongside the 36-Item Short-Form Health Survey (SF-36) to evaluate QoL. Data analysis involved Pearson correlation and multiple regression to explore the association of pain intensity on QoL.

RESULTS

All pain scales showed significant negative correlations with QoL. The MPQ exhibited a significant association, suggesting its comprehensive nature captures the multidimensional association of pain more effectively. Regression analysis identified pain intensity, age, and duration of chronic pain as significant predictors of reduced QoL.

CONCLUSIONS

The findings emphasize the importance of selecting appropriate pain assessment tools that reflect the complex nature of pain in elderly patients. Implementing comprehensive pain assessments like the MPQ can enhance individualized care strategies and potentially improve the QoL in this population. This study underscores the role of nurses in optimizing pain management approaches tailored to the elderly.

The effect of three different nonpharmacological methods on cannulation success during peripheral intravenous catheter placement in the emergency unit: a randomized controlled trial

BACKGROUND

Peripheral intravenous catheterization is frequently performed in emergency units, but it is a procedure which is difficult for healthcare professionals and painful for patients. The primary objective of the present study was to examine the effect on venous dilation, procedure duration and pain severity of local heat, cold and vibration applications performed on the intervention area before peripheral intravenous catheterization in adults. The second objective of the study was to examine the effects of age and gender variables on the participants' pain intensity levels.

METHODS

A single-blinded randomized controlled trial. The study included 120 adults who were randomly selected between March and August 2023. One application group (n = 30) received local heat application, one group (n = 30) received local cold application, and one (n = 30) received local vibration using the Buzzy® device. The applications, to the site of the peripheral intravenous catheterization, lasted one minute. The control group (n = 30) received standard peripheral intravenous catheterization application. The groups' vein dilation was assessed with the vein assessment scale, pain felt during catheterization with the visual analog scale, and the duration of the procedure with a chronometer.

RESULTS

It was found that the venous dilation of the cold application group was significantly higher (p = 0.010, p = 0.015 respectively) and procedure duration was shorter (p = 0.013, p < 0.001 respectively) than that of the heat and vibration application groups, and its pain severity was significantly lower (p = 0.002, p = 0.001 and p = 0.001 respectively) than that of the control group and the heat and vibration application groups.

CONCLUSIONS

It was determined that local cold application for one minute to the area of peripheral intravenous catheterization increased venous dilation, shortened application time, and reduced pain.

Impact of disabilities in activities of daily living on opioid use for chronic pain in older adults: an exploratory secondary analysis from ELSI-Brazil

OBJECTIVES

Problematic use of opioids by older adults is associated with adverse effects and has become a public health crisis worldwide. Ageing-related disabilities in activities of daily living (ADL) could promote unnecessary use of opioids in this population. This study evaluates the association between ADL disability and opioid consumption in Brazilian older adults.

STUDY DESIGN

Study design- cross-sectional secondary data analysis of the second wave of the Brazil Longitudinal Study of Ageing (ELSI-Brazil).

METHODS

Data from the second wave of the Brazil Longitudinal Study of Ageing (ELSI-Brazil) were used. Older adults with chronic pain were included. ADL disability was measured using the Katz Index. The primary outcome was opioid consumption for chronic pain. The primary association was explored using logistic regression models adjusting for predetermined confounders. Sensitivity analyses evaluating model performance were done by calibrating and validating the model using randomly split equal sets.

RESULTS

In those who reported presence of chronic pain (n = 2865), the prevalence of opioid use was 29% (95% CI:23.1%-35.6%). In adjusted models, participants with moderate and severe ADL disability had 1.6 (95% CI:1.13-2.32; P = 0.009) and 3.8 (95% CI: 1.80-7.90; P < 0.001) times higher odds of opioid consumption compared to no disability, respectively. Being female, alcohol consumption, higher pain intensity, history of dementia, fractures, and presence of ≥2 comorbidities were significantly associated with increased opioid use (P < 0.05).

CONCLUSION

Nearly one-third of the Brazilian elderly population experiencing chronic pain reported using opioids. The functional decline during the process of ageing appears to be a risk factor for pain intolerance and opioid use. Multidisciplinary approaches to detect early ADL disabilities and improve mobility and access to assistive technologies need to be established to prevent opioid overuse and addiction in elderly populations.

Pain Prevalence and Pain Management in Nursing Home Residents With Cognitive Impairment. Results From Five Multicenter Cross-Sectional Surveys in Germany Between 2014 and 2018

BACKGROUND

Pain management depends on continuous pain assessment and a pain concept. In particular, pain assessment and treatment are major challenges for nursing home residents (NHR) with cognitive impairment (CI). Many caregivers often lack the knowledge to recognize and appropriately treat pain in this vulnerable group. Little is known about the proportion of NHR who are fundamentally dependent on external assessment for pain due to CI.

OBJECTIVE

The aim of the study was to determine pain prevalence and management among NHR with and without CI. A second objective was to determine the proportion of NHR who are dependent on external assessment for pain.

METHODS

Information on pain was collected from 3,437 NHR in multicenter cross-sectional surveys in 51 German nursing homes between 2014 and 2018. The presence of current pain in one-to-one interviews was determined as well as dependencies on third-party information, number of daily pain recordings, and administration of medication for pain. The analysis included a contingency table and log regression analyses.

RESULTS

Pain prevalence was 24.9% among NHR with severe CI and 40.4% among NHR without CI. Overall, 19.8% of all NHRs relied on a third-party assessment of pain. Significantly, NHR with severe CI were less likely to be classified as having pain (OR 0.51), to be assessed for pain several times a day (OR 0.53) or to receive pain medication (OR 0.55) compared with NHR without CI. No influence on pain management was shown for the type of pain assessment.

CONCLUSIONS

The study provides evidence of significant deficits in pain management among NHR with moderate and severe CI in nursing homes in Germany. NHR with moderate and severe CI are significantly less likely to be observed for pain or classified as pain sufferers and receive significantly less pain medication than NHR without CI. Intensive training of staff on pain management of NHR with severe CI is recommended.

Assessing pain in older people with normal, mildly impaired or severely impaired cognition

Pain is a relatively common experience among older people, but unrelieved pain has significant functional, cognitive and emotional consequences for this population. A comprehensive and accurate pain assessment is essential for effective pain management. Self-report tools are suitable to assess pain in older people with normal or mildly impaired cognition, while observational tools are suitable for use with those with significant cognitive impairment or communication difficulties. However, pain assessment in older people can be challenging. The use of one tool on its own is rarely sufficient and it is crucial to involve family carers in assessment of pain in older people with severe cognitive impairment. This article discusses different tools and strategies, including the benefits and limitations, for assessing pain in older people.

Association between sleep duration and chronic musculoskeletal pain in US adults: a cross-sectional study

Background

This study aims to explore the association between sleep duration and the prevalence of chronic musculoskeletal pain (CMP).

Methods

A cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (NHANES) 2009-2010, which involved multiple centers across the United States. The study included 3,904 adults selected based on age and complete data availability. Demographic variables such as gender, age, race, and socioeconomic status (represented by the poverty-to-income ratio) were considered.

Results

Of the participants, 1,595 reported less than 7 h of sleep, 2,046 reported 7-8 h, and 263 reported more than 9 h of sleep. Short sleep duration was associated with higher odds of CMP (OR, 1.611, 95% CI: 1.224-2.120, p = 0.005). Long sleep duration also showed a higher prevalence (OR, 1.751; 95% CI, 0.923 to 3.321; p = 0.059), although this result was not statistically significant. A U-shaped relationship emerged (Effective degree of freedom (EDF) = 3.32, p < 0.001), indicating that 7 h of sleep was associated with the lowest odds of CMP. In individuals with sleep durations less than 7 h, each hour increment correlated with 22.8% reduced odds of CMP (OR, 0.772; 95% CI, 0.717-0.833; p = 0.002). Beyond 7 h, each hour increment was associated with 38.9% increased odds of CMP (OR, 1.389; 95% CI, 1.103-1.749; p = 0.049).

Conclusion

The findings suggest that both insufficient and excessive sleep durations are linked to a higher prevalence of CMP, highlighting the importance of optimal sleep duration for musculoskeletal health.

Pain Sensitization and Association With Baseline Factors in Elderly Patients With Distal Radius Fracture: A Cross-Sectional Study

BACKGROUND

The aim of this study was to describe the presence of pain sensitization (PS) and its association with baseline factors after cast removal in patients older than 60 years with distal radius fracture (DRF) treated conservatively.

METHODS

This cross-sectional study included 220 patients older than 60 years with extra-articular DRF who completed the Pain Sensitivity Questionnaire (PSQ). Patients with PSQ score > 7 points were considered positive for PS. In addition, sociodemographic, anthropometrics, clinical, radiological, lifestyle behaviors, pain-related psychological factors, and functional outcomes were analyzed as baseline predictors, all measured were performed 2 weeks after cast removal.

RESULTS

A total of 159 patients (72.3%) showed PS. The results showed an association between higher values of PSQ-total with the affected dominant hand (β = 1.1; P = 0.04), high energy of injury (β = 3.5; P < .001), extra-articular comminuted metaphyseal DRFs (β = 1.8; P < .001), lower values of Rapid Assessment of Physical Activity questionnaire (β = 3.1; P < .001), higher values of Pittsburgh Sleep Quality Index (β = 2.5; P < .001), higher values of Tampa Scale of Kinesiophobia (β = 1.9; P < .001), higher values of Pain Catastrophizing Scale (β = 1.8; P < .001), higher values of Disabilities of the Arm, Shoulder and Hand questionnaire (β = 1.6; P < .001), lower values of grip strength (β = 1.4; P < .001) and higher values of Visual analog scale (β = 4.2; P < .001).

CONCLUSIONS

A high percentage of patients older than 60 years with extra-articular DRFs present PS at 2 weeks after cast removal. Our results may help physicians and physiotherapists identify risk and/or prognostic baseline factors for the occurrence of PS after DRF, and the need for a therapeutic approach that incorporates the clinical management of this condition in these patients.

Psychosocial Phenotypes of Older Adults With Pain and Their Associated Clinical Outcomes

A comprehensive understanding of the patterns of psychosocial characteristics in older adults with pain is needed. Our objectives were to (1) identify psychosocial phenotypes (comprising depression, anxiety, affect, self-realization, resilience, and social participation) among older adults with pain and (2) compare pain characteristics, physical health, and cognition among the identified phenotypes. Using cross-sectional 2021 data from the National Health and Aging Trends Study, we performed latent class analysis to identify four psychosocial phenotypes of older adults with pain (N = 1903): Favorable (best psychosocial characteristics, 67.7%), Adverse (worst psychosocial characteristics, 4.9%), Intermediate (moderate scores on psychosocial variables, 12.6%), and Compensated (moderate scores with relatively high self-realization and resilience, 14.9%). Phenotypes with less psychosocial adversity had generally better clinical outcomes. Future research should explore precision pain management interventions in older adults based on their psychosocial phenotypes, longitudinal trajectories of phenotypes, and technology-based, point-of-care clinical insights for pain management.

Sedentary behavior, increasing age, and overweight/obesity increase the presence and intensity of the chronic joint pain in individuals affected by Chikungunya fever

BACKGROUND

Chikungunya fever (CF) is a viral disease, transmitted by alphavirus through Aedes aegypti, and albopictus mosquitoes, affecting several people, mainly in tropical countries, when its transmitter is not under control, and the main symptom of the chronic phase of CF is joint pain.

OBJECTIVES

The primary objective of this study was to observe the prevalence, most affected joints, and intensity of chronic joint pain in individuals affected by CF, and also identify the factors associated with chronic joint pain in these individuals.

METHODS

Cross-sectional study that evaluated one hundred and thirty volunteers, of both sexes, aged between 20-65 years, with a clinical and/or laboratory diagnosis of CF. The presence of joint pain was investigated using the Brazilian version of the Nordic Questionnaire of Musculoskeletal Symptoms and the intensity of pain using the Visual Analogue Scale.

RESULTS

Of the 130 volunteers evaluated, n = 112 (86%) reported currently experiencing chronic joint pain, persistent, for approximately 38.6 ± 1.73 months, with the greatest predominance in the morning (58%). The joints most affected by pain were: the ankles (65.5%), interphalangeal joints of the hands (59.2%), and knees (59.2%). The joints that presented the greatest intensity of pain were: the ankles (5.13 ± 0.34), interphalangeal joints of the hands (4.63 ± 0.34), and knees (4.33 ± 0.33). Sedentary behavior (p = 0.037), increasing age (p = 0.000), and overweight/obesity (p = 0.002) were factors associated with chronic joint pain.

CONCLUSION

A high prevalence of chronic, persistent joint pain was observed, with a greater prevalence in the morning. The joints most affected by chronic pain and with the greatest pain intensity were the ankles, and interphalangeal joints of the hands and knees. Sedentary behavior, increasing age, and overweight/obesity were the factors associated with chronic joint pain in individuals affected by CF in this study. Key Points • Individuals affected by CF had a high prevalence of chronic joint pain, persistent and more prevalent in the mornings • The ankles and interphalangeal joints of the hands and knees were the joints with the highest prevalence of pain • The ankles and interphalangeal joints of the hands and knees were the joints with the greatest pain intensity • Sedentary behavior, increasing age, and overweight/obesity were factors associated with chronic joint pain in individuals affected by CF.

Comparison of Post-Hemorrhoid Surgery Pain Profiles in Older and Younger Adults

INTRODUCTION

Older and younger adults are offered similar analgesic options after hemorrhoid surgery (HS), but the differences in pain between the two populations are unknown. This study aims to compare postoperative pain outcomes after HS in older and younger individuals.

METHODS

This is a retrospective analysis of electronic medical records of patients who underwent HS between 2018 and 2023. Patients were excluded if additional anorectal procedures were performed at the time of HS. Data related to pain-related outcomes were compiled: (1) need for narcotic prescription refills; (2) documentation of a pain-related phone call within 30 d; (3) urgent postoperative office visit before regular scheduled follow-up; and (4) pain-related postoperative emergency department visits. Associations between age and pain-related outcomes were tested using Fisher's exact test, chi-square test, and covariate adjusted logistic regression modeling.

RESULTS

There were a total of 249 patients, 60 older adults, and 189 younger adults. Compared to younger patients, older adults demonstrated a reduced frequency of pain-related phone calls (10.3 versus 32.1%, P < 0.01) and opioid refills (0 versus 14.4%, P < 0.01). After adjusting for confounders, older age remained inversely associated with pain-related postoperative phone calls (odds ratio = 0.25, 95% confidence interval = [0.1-0.6], P = 0.003).

CONCLUSIONS

Older adults had better pain outcomes after HS in comparison to younger patients. These findings suggest that the postoperative analgesic needs of older patients after HS are lower than those of younger patients. Decisions regarding opioid prescription in older adults recovering from HS should be tailored to avoid narcotic-related complications.

More Movement, Less Bodily Pain? Findings From a Large, Representative Multi-District Aging Study in Ghana

OBJECTIVE

The association of physical activity (PA) with pain has been characterized. Although the literature largely comes from high-income countries, the mechanistic pathways underlying this association remain unknown, particularly in low- and middle-income countries (LMICs). We aim to examine the association between meeting the World Health Organization (WHO) PA guidelines and pain among aging adults and identify the factors that may mediate this association.

DESIGN

We used a quantitative cross-sectional study design.

SETTING AND PARTICIPANTS

Representative data from adults aged ≥50 years who participated in the Aging, Health, Psychological Well-being, and Health-seeking Behavior Study were used.

METHODS

PA was defined using the International Physical Activity Questionnaire (IPAQ). Self-reported pain experience using a cross-culturally validated item over the past month assessed pain severity. Adjusted multivariable ordinal logistic regression and mediation models quantified the hypothesized associations.

RESULTS

The analysis included 1201 adults (mean 66.1 ± 11.9 years; 63.3% female). After adjusting for confounders, adhering to the WHO-recommended PA guidelines was associated with 42% lower odds for severe/extreme pain [odds ratio (OR) 0.58, 95% CI 0.44-0.77]. The association was much stronger among men (OR 0.52, 95% CI 0.31-0.85) than women (OR 0.60, 95% CI 0.42-0.87). The PA-pain association was explained by functional limitations (84.7%), self-rated health (76.6%), sleep problems (20.4%), and injury (6.6%).

CONCLUSIONS AND IMPLICATIONS

Moving more was associated with less pain in older adults from LMICs. Interventions for pain management in old age may focus on enhancing compliance with PA doses, particularly in LMICs. However, longitudinal data will need to confirm these findings.

Pain in non-communicative older adults beyond dementia: a narrative review

Aging is associated with an increased risk of developing pain, especially in the presence of concurrent chronic clinical conditions. Similarly, multimorbidity can affect the perception and ability of older adults to appropriately respond to and communicate pain, and there is a clinical heterogeneity in the processing of painful sensations in different neurological conditions. The present narrative review is aimed at assessing the prevalent diseases associated with poor communication and pain in older adults, together with the available diagnostic instruments for the clinical assessment of pain in such a vulnerable population. Dementia was the most described pathology identified in the current literature associated with poor communication in older adults affected by pain, along with Parkinson's disease and stroke. Notably, a common pattern of pain behaviors in these neurological disorders also emerged, indicating potential similarities in the clinical presentation and appropriate diagnostic workout. At the same time, there are many differences in the way patients express their pain according to their main neurological pathology. In addition to this, although a plethora of observation-based tools for pain in patients with dementia have been developed, there is no gold standard, and the clinical utility of such measurements is still largely unaddressed. Meanwhile, there is substantially no standardized observation-based tool for pain in non-communicative patients with Parkinson's disease, and only a few for stroke. Overall, the present narrative review provides an update on the prevalent diseases beyond dementia associated with a communicative disability and a painful condition in older adults.

The Impact of Pain on Mobility in Patients with Cancer

OBJECTIVES

Provide an overview of how pain impacts mobility in patients with cancer.

METHODS

A literature search was conducted in PubMed and on Google Scholar using search terms, cancer pain with mobility, acute and chronic pain syndromes, enhanced recovery after surgery, nursing care, and rehabilitation. Peer-reviewed research studies, review articles, and pain guidelines and position papers were reviewed to provide an overview on cancer pain, its impact on mobility, and the nurse's role in managing pain and optimizing mobility and functional outcomes.

RESULTS

Firty-two references were included in this overview. This body of literature is replete with studies on the management of pain; however, the tie between pain and mobility has not been well described aside from the breakthrough pain literature. This manuscript weaves these two important concepts together to better inform nurses and other clinicians regarding the importance of managing pain to even begin mobilizing patients, especially following surgery and for other painful conditions.

CONCLUSIONS

Oncology nurses play an integral role in assessing and managing cancer pain. It is important for nurses to recognize how their pain management interventions lead to improved mobility and functioning in patients with cancer.

IMPLICATIONS FOR NURSING PRACTICE

Nurses comprise the largest workforce around the globe and are well-equipped to assess and manage cancer pain in all cancer care settings. As leaders within the healthcare team, making recommendations to better control pain and communicating with other team members regarding the pain plan is essential in improving mobility in patients with cancer.

Enkephalins and Pain Modulation: Mechanisms of Action and Therapeutic Perspectives

Enkephalins, a subclass of endogenous opioid peptides, play a pivotal role in pain modulation. Enkephalins primarily exert their effects through opioid receptors located widely throughout both the central and peripheral nervous systems. This review will explore the mechanisms by which enkephalins produce analgesia, emotional regulation, neuroprotection, and other physiological effects. Furthermore, this review will analyze the involvement of enkephalins in the modulation of different pathologies characterized by severe pain. Understanding the complex role of enkephalins in pain processing provides valuable insight into potential therapeutic strategies for managing pain disorders.

eHealth-Integrated Psychosocial and Physical Interventions for Chronic Pain in Older Adults: Scoping Review

BACKGROUND

Chronic noncancer pain (CNCP) is highly present among older adults, affecting their physical, psychological, and social functioning. A biopsychosocial multimodal approach to CNCP management is currently extensively suggested by international clinical practice guidelines. Recently, the growing development and application of eHealth within pain management has yielded encouraging results in terms of effectiveness and feasibility; however, its use among the older population remains underexamined.

OBJECTIVE

The overall aim of this scoping review was to systematically map existing literature about eHealth multimodal interventions (including both physical and psychosocial components) targeting older adults with CNCP.

METHODS

This review adhered to the JBI methodology, a protocol was a priori registered as a preprint on the medRxiv platform, and the results were reported according to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Four electronic databases (PubMed, Cochrane Central Register of Controlled Trials, Web of Science, and PsycINFO) were systematically searched for relevant articles. Studies were included if they reported on multimodal interventions (including both physical and psychosocial components) delivered through any eHealth modality to an older population with any type of CNCP. Two reviewers selected the studies: first by screening titles and abstracts and second by screening full-text articles. The quality of the included studies was evaluated using the Quality Assessment Tool for Studies with Diverse Designs. The results of the studies were summarized narratively.

RESULTS

A total of 9 studies (n=6, 67% published between 2021 and 2023) with quality rated as medium to high were included, of which 7 (78%) were randomized controlled trials (n=5, 71% were pilot and feasibility studies). All the included studies evaluated self-management interventions, most of them (n=7, 78%) specifically designed for older adults. The participants were aged between 65 and 75 years on average (mean 68.5, SD 3.5 y) and had been diagnosed with different types of CNCP (eg, osteoarthritis and chronic low back pain). Most of the included studies (5/9, 56%) involved the use of multiple eHealth modalities, with a higher use of web-based programs and video consulting. Only 1 (11%) of the 9 studies involved a virtual reality-based intervention. The evaluated interventions showed signs of effectiveness in the targeted biopsychosocial outcomes, and the participants' engagement and ratings of satisfaction were generally positive. However, several research gaps were identified and discussed.

CONCLUSIONS

Overall, of late, there has been a growing interest in the potential that eHealth multimodal interventions offer in terms of improving pain, physical, and psychosocial outcomes in older adults with CNCP. However, existing literature on this topic still seems scarce and highly heterogeneous, with few proper randomized controlled trials, precluding robust conclusions. Several gaps emerged in terms of the older population considered and the lack of evaluation of comorbidities.

Deprescribing NSAIDs: The Potential Role of Community Pharmacists

Non-steroidal anti-inflammatory drugs (NSAIDs) are largely used for controlling various pain conditions and are widely available in community pharmacies, with and without prescription. Despite their effectiveness, NSAIDs can pose significant risks due to potential side effects and drug interactions, particularly in polypharmacy and comorbidity contexts and for vulnerable users. This study investigated whether and how NSAIDs deprescribing can be conducted at the community pharmacy level by assessing pharmacists' confidence, attitudes, and potential barriers and facilitators. Additionally, we aimed to identify any deprescribing guidelines that pharmacists could use. A literature search and a cross-sectional digital questionnaire targeting community pharmacists in Norway were conducted. Results showed that study participants (N = 73) feel confident in identifying needs for deprescribing NSAIDs but barriers such as time constraints, lack of financial compensation, and communication challenges were noted. Participants reported positive attitudes toward deprescribing but highlighted a need for better guidelines and training. This study highlights a gap in specific guidelines for deprescribing NSAIDs and a potential for enhancing pharmacists' roles in the deprescribing process, for example, through training and improved financial incentives. Further research is encouraged to develop concrete strategies for an effective implementation where community pharmacists can be involved in the deprescribing of NSAIDs.

Understanding public perceptions and discussions on diseases involving chronic pain through social media: cross-sectional infodemiology study

BACKGROUND

Chronic pain is a highly prevalent medical condition that negatively impacts quality of life and is associated with considerable functional disability. Certain diseases, such as fibromyalgia, headache, paraplegia, neuropathy, and multiple sclerosis, manifest with chronic pain.

OBJECTIVE

The aim of this study is to examine the number and type of tweets (original or retweet) related to chronic pain, as well as to analyze the emotions and compare the societal impact of the diseases under study.

METHODS

We investigated tweets posted between January 1, 2018, and December 31, 2022, by Twitter users in English and Spanish, as well as the generated retweets. Additionally, emotions were extracted from these tweets and their diffusion was analyzed. Furthermore, the topics most frequently discussed by users were collected.

RESULTS

A total of 72,874 tweets were analyzed, including 44,467 in English and 28,407 in Spanish. Paraplegia represented 23.3% with 16,461 of the classified tweets, followed by headache and fibromyalgia with 15,337 (21.7%) and 15,179 (21.5%) tweets, respectively. Multiple sclerosis generated 14,781 tweets (21%), and the fewest tweets were related to neuropathy with 8,830 tweets (12.5%). The results showed that the primary emotions extracted were "fear" and "sadness." Additionally, the reach and impact of these tweets were investigated through the generated retweets, with those related to headaches showing the highest interest and interaction among users.

CONCLUSION

Our results underscore the potential of leveraging social media for a better understanding of patients suffering from chronic pain and its impact on society. Among the most frequently encountered topics are those related to treatment, symptoms, or causes of the disease. Therefore, it is relevant to inform the patient to prevent misconceptions regarding their illness.

Gender differences in the quantitative and qualitative assessment of chronic pain among older people

Background

Pain, regardless of its causes, is a subjective and multidimensional experience that consists of sensory, emotional and cognitive factors that cannot be adequately captured by a single number on a pain scale. The aim of the study was to understand gender differences in the assessment of quantitative and qualitative chronic pain among older people.

Methods

The study used a questionnaire that included questions about demographic and social characteristics as well as the following scales: Abbreviated Mental Score (AMTS), Personal Activities of Daily Living (PADL) by Katz, Instrumental Activities of Daily Living (IADL) by Lawton, Geriatric Depression Scale (GDS-15), McGill Pain Questionnaire (MPQ).

Results

The pain rating index based on rank values of adjectives was higher among women than men (18.36 ± 7.81 vs. 17.17 ± 9.69, p = 0.04). The analysis of the frequency of selection of individual adjectives describing the sensory aspects of pain showed that men described the pain as "stabbing" more often than women (26.1% vs. 14.3%, p < 0.05). Women chose adjectives from the emotional category more often than men (59.8% vs. 75.4%, p < 0.05), describing the pain as "disgusting" (8.9% vs. 1.4%, p < 0.05), "unbearable" (19.6 vs. 4.3, p < 0.05). In the subjective category, there was a difference between women and men in terms of describing pain as "terrible" (23.2% vs. 7.2%, p < 0.05) and as "unpleasant" (11.6% vs. 23.3%, p < 0 0.05).

Conclusion

When referring to pain, women tend to employ more detailed and factual language, indicative of heightened emotional sensitivity. Men tend to use fewer words and focus on the sensory aspects of pain. Subjective aspects of pain were demonstrated by both women and men.

Effects of proactive healthcare on pain, physical and activities of daily living functioning in vulnerable older adults with chronic pain: a pragmatic clinical trial with one- and two-year follow-up

PURPOSE

To investigate the changes in pain, physical and activities of daily living (ADL) functioning in vulnerable older adults with chronic pain after proactive primary care intervention.

METHODS

This study was embedded in a prospective, pragmatic, matched-control multicenter trial at 19 primary care practices in Sweden, with proactive medical and social care (Intervention Group, IG, n = 134) in comparison with usual care (Control Group, CG, n = 121). Patients with chronic pain, defined as pain experienced longer than 3 months, were included in this subgroup analysis. Data on pain aspects, physical and ADL functioning were collected in the questionnaires at baseline, one- and two-year follow-up (FU-1 and FU-2). Data on prescribed pain medications was collected by local health authorities.

RESULTS

Mean age was 83.0 ± 4.7 years with almost equal representation of both genders. From baseline until FU-2, there were no significant within-group or between-group changes in pain intensity. Small adjustments of pain medication prescriptions were made in both groups. Compared to FU-1, the functional changes were more measurable at FU-2 as fewer participants had impaired physical functioning in IG (48.4%) in comparison to CG (62.6%, p = 0.027, Effect Size φ = 0.14). Higher scores of ADL-staircase (more dependent) were found in both groups (p < 0.01, Effect Size r = 0.24 in CG and r = 0.16 in IG).

CONCLUSION

Vulnerable older adults with chronic pain seemed to remain physical and ADL functioning after proactive primary care intervention, but they may need tailored strategies of pain management to improve therapeutic effects.

Substance P's Impact on Chronic Pain and Psychiatric Conditions-A Narrative Review

Substance P (SP) plays a crucial role in pain modulation, with significant implications for major depressive disorder (MDD), anxiety disorders, and post-traumatic stress disorder (PTSD). Elevated SP levels are linked to heightened pain sensitivity and various psychiatric conditions, spurring interest in potential therapeutic interventions. In chronic pain, commonly associated with MDD and anxiety disorders, SP emerges as a key mediator in pain and emotional regulation. This review examines SP's impact on pain perception and its contributions to MDD, anxiety disorders, and PTSD. The association of SP with increased pain sensitivity and chronic pain conditions underscores its importance in pain modulation. Additionally, SP influences the pathophysiology of MDD, anxiety disorders, and PTSD, highlighting its potential as a therapeutic target. Understanding SP's diverse effects provides valuable insights into the mechanisms underlying these psychiatric disorders and their treatment. Further research is essential to explore SP modulation in psychiatric disorders and develop more effective treatment strategies.

Effects of hand-press pellet on pain and daily life of elders with chronic lower back pain: randomized controlled trial

BACKGROUND

For elderly people with chronic lower back pain who need long-term management, there is a need for a nursing intervention study that is effective, is easy to perform, and applies complementary and alternative therapies to manage pain without repulsion. Hand pressure therapy is a treatment indigenous to Korea used to reduce pain and improve functions of daily life by applying acupuncture, pressure sticks, and moxibustion to parts of the hand as they relate to parts of the body. This research is to identify the effects of pellet pressed on the hand on pain and the daily lives of elders with chronic lower back pain (CLBP).

METHODS

The hand pressed-pellet intervention period was six weeks long. Twenty-seven patients in the intervention group and twenty-four patients in the placebo control group were recruited from elderly over sixty-five who used welfare centers. In the intervention group, hand pressed-pellet therapy was conducted in eleven acupressure response zones related to CLBP, and the placebo control group was provided with similar therapy and zones, but unrelated to CLBP. The research tool measured the intensity of CLBP using the Visual Analogue Scale (VAS), the Korean Owestry Disability Index (K-ODI), which are subjective indicators, and the Compact Digital Algometer, which is an objective indicator.

RESULT

The pain intensity (VAS) measured after six weeks of hand pressed-pellet therapy showed significant difference between the two groups compared to their pain before the experiment (F = 60.522, p < .001). There was a significant difference between the two groups in the pain pressure threshold using pressure statistics (F = 8.940, p < .001), and in CLBP dysfunction evaluation index (K-ODI) after applying pressed pellet to the hand (Z = - 3.540, p < .001).

CONCLUSION

Subjective indicators were measured to verify the effect of hand pressed-pellet therapy on CLBP, and the result confirmed that the hand pressed-pellet therapy was effective in alleviating CLBP.

TRIAL REGISTRATION

The study was registered retrospectively with reference number KCT0008024 on 23/12/2022.

Efficacy of serious games for chronic pain management in older adults: A systematic review and meta-analysis

AIMS AND OBJECTIVES

To synthesise and appraise the evidence of the efficacy of serious games in reducing chronic pain among older adults.

BACKGROUND

Chronic pain in older adults generally results in a substantial handicap due to decreased mobility, exercise avoidance and various concerns that affect their overall quality of life. While serious games have been widely used as a pain management approach, no reviews have thoroughly examined their efficacy for chronic pain management in older adult populations.

DESIGN

A systematic review and meta-analysis.

METHODS

The CINAHL, the Cochrane Library, Embase, Medline, PubMed and Web of Science databases were comprehensively searched to find articles published from their inception until 17 April 2023. RoB-2 was used to assess the risk of bias in the included studies. The efficacy of serious games for pain management in older individuals was investigated using pooled standardised mean differences (SMDs) in pain reduction using a random effect model.

RESULTS

The meta-analysis comprised nine randomised controlled trials that included 350 older adult patients with pain. Serious games effectively alleviated pain in this group (pooled SMD = -0.62; 95% confidence interval: -1.15 to -0.10), although pain-related disability and fear require further investigation.

CONCLUSIONS

Serious games tended to effectively reduce pain in this older adult group; however, due to a lack of randomised controlled trials, the analysis found lower effectiveness in reducing pain-related disability and fear. Further studies are accordingly required to confirm these findings.

RELEVANCE TO CLINICAL PRACTICE

The findings of the study emphasise the importance of serious games to increase the motivation of older adults to exercise as one of the safe and extensively used pain management strategies. Serious games that effectively reduce chronic pain in older adults are characterised as consisting of diverse physical activities delivered through consoles, computer-based activities and other technologies.

PATIENT OR PUBLIC CONTRIBUTIONS

Serious games are recommended as being potentially useful and practical for reducing pain in older adults.

How is family health related to health-related quality of life among middle-aged and older adults in rural China? A cross-sectional study

BACKGROUND

Health-related quality of life (HRQOL) is unequal between countries and regions, and the emphasis on HRQOL of populations of low-income countries and regions is unprecedented.

OBJECTIVES

To examine the association between family health and HRQOL among middle-aged and older adults in rural China, and determine whether this association differs by age, gender and chronic disease subgroup.

METHODS

Cross-sectional survey carried out from July to September 2021. The participants were 1059 people aged 46 and over living in rural China. We used the European Quality of Life Five Dimension Five Level (EQ-5D-5L) and Family Health Scale-Short Form (FHS-SF) to assess health-related quality of life (HRQOL) and family health, respectively.

RESULTS

The mean EQ-VAS was 75.66, the mean EQ index score was 0.92, and the mean FHS was 37.90 in rural middle-aged and older adults. After Bonferroni correction, generalised linear regression models showed that FHS was significantly associated with the EQ-VAS (β = 0.829; 95% confidence interval [CI]: 0.660 to 0.997; p < .001) and the EQ index score (β = 0.003; 95%CI: 0.001 to 0.004; p < .001). Binary logistic regression models showed that FHS was associated with three dimensions of HRQOL (mobility, self-care and usual activities) (p < .01). Based on subgroup analyses, the effect of FHS on EQ-VAS and the EQ index score was significant in three subgroups after Bonferroni correction (p < .01), but the association between FHS and the dimensions of HRQOL differed by age, gender and chronic disease group (p > .01).

CONCLUSIONS

This study is the first to explore that family health and its dimensions are significant positive predictors of HRQOL among middle-aged and older adults in rural China. Family-based measures may have more potential and value because better family health significantly improves HRQOL.

IMPLICATIONS FOR PRACTICE

In the health strategy, the government and primary health care workers should include family health as an indicator and assess it before and after the implementation of the strategy.

Immune receptors and aging brain

Aging brings about a myriad of degenerative processes throughout the body. A decrease in cognitive abilities is one of the hallmark phenotypes of aging, underpinned by neuroinflammation and neurodegeneration occurring in the brain. This review focuses on the role of different immune receptors expressed in cells of the central and peripheral nervous systems. We will discuss how immune receptors in the brain act as sentinels and effectors of the age-dependent shift in ligand composition. Within this 'old-age-ligand soup,' some immune receptors contribute directly to excessive synaptic weakening from within the neuronal compartment, while others amplify the damaging inflammatory environment in the brain. Ultimately, chronic inflammation sets up a positive feedback loop that increases the impact of immune ligand-receptor interactions in the brain, leading to permanent synaptic and neuronal loss.
