Factors associated with self-reports of limitations in activities of daily living among Medicare Fee-for-Service recipients.

BACKGROUND: Physical function is an important indicator of physical health and predicts mortality. This study identified characteristics associated with limitations in Medicare recipients' activities of daily living. METHODS: 2019 Consumer Assessment of Healthcare Providers and Systems Fee-for-Service Medicare Survey data: 79,725 respondents (34% response rate) who were 65 and older and 53% female; 7% Black, 5% Hispanic, 4% Asian American, Native Hawaiian, or other Pacific Islander, 2% Multiracial, 1% American Indian/Alaskan Native; 35% with high school education or less. Walking, getting in and out of chairs, bathing, dressing, toileting, and eating (scored as having no difficulty versus being able to do with difficulty or unable to do) and a scale of these items were regressed on patient characteristics. RESULTS: After adjustment for all characteristics, function limitations were found for those who smoked (effect sizes of significant associations range .04-.13), had chronic health conditions (.02-.33), were 85 years or older (.09-.46), needed assistance completing the survey (.32-1.29), were female (.05-.07), and had low income and assets (.15-.47). CONCLUSIONS: These nationally representative U.S. estimates of physical function characteristics are useful for interventions for vulnerable population subgroups.

Using a measurement type-independent metric to compare patterns of determinants between patient-reported versus performance-based physical function in hemodialysis patients.

PURPOSE: We applied a previously established common T-score metric for patient-reported and performance-based physical function (PF), offering the unique opportunity to directly compare measurement type-specific patterns of associations with potential laboratory-based, psychosocial, sociodemographic, and health-related determinants in hemodialysis patients. METHODS: We analyzed baseline data from the CONVINCE trial (N = 1,360), a multinational randomized controlled trial comparing high-flux hemodialysis with high-dose hemodiafiltration. To explore the associations of potential determinants with performance-based versus patient-reported PF, we conducted multiple linear regression (backward elimination with cross-validation and Lasso regression). We used standardized T-scores as estimated from the PROMIS PF short-form 4a (patient-reported PF) and the Physical Performance Test (performance-based PF) as dependent variables. RESULTS: Performance-based and patient-reported PF were both significantly associated with a laboratory marker-based indicator of muscle mass (simplified creatinine index), although the effects were relatively small (partial f2 = 0.04). Age was negatively associated with PF; the effect size was larger for performance-based (partial f2 = 0.12) than for patient-reported PF (partial f2 = 0.08). Compared to performance-based PF, patient-reported PF showed a stronger association with self-reported health domains, particularly pain interference and fatigue. When using the individual difference between patient-reported and performance-based T-scores as outcome, we found that younger age and more fatigue were associated with lower patient-reported PF compared to performance-based PF (small effect size). CONCLUSION: Patient-reported and performance-based assessments were similarly associated with an objective marker of physical impairment in hemodialysis patients. Age and fatigue may result in discrepancies when comparing performance-based and patient-reported scores on the common PF scale.

One-year changes in body composition and musculoskeletal health following metabolic/bariatric surgery.

CONTEXT: There are limited comparative studies between one anastomosis gastric bypass (OAGB) versus Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on body composition and musculoskeletal health. OBJECTIVE: To compare changes in body composition, areal bone mineral density (aBMD), muscle strength, and physical function in the first year following OAGB, RYGB and SG within a UK-based healthcare setting. METHODS: This is a secondary analysis of the BARI-LIFESTYLE trial in 119 adults (77% women; mean±SD, age: 45.9±10.3 years; BMI: 43.6±5.5 kg/m2) who underwent OAGB (n=19), RYGB (n=39) and SG (n=61). Body composition and aBMD by dual energy x-ray absorptiometry, handgrip strength, sit-to-stand (STS) test and 6-minute walking test (6MWT) were assessed pre-surgery and at 12 months post-surgery. RESULTS: OAGB, RYGB, and SG exhibited similar reductions in body weight, body fat and lean mass (within-group comparisons, p<0.001). All surgery types were associated with reductions in aBMD at the total hip, femoral neck, and lumbar spine, which were more pronounced after OAGB and RYGB compared to SG (all p<0.03), though no difference between OAGB and RYGB. Despite reductions in absolute handgrip strength, relative handgrip strength, STS test and 6MWT improved post-surgery (all p<0.02), with no differences by surgical procedure. CONCLUSION: OAGB, RYGB, and SG resulted in comparable weight loss, changes in body composition and improvements in relative muscle strength and physical function. OAGB and RYGB, compared with SG, led to greater BMD reductions at clinically relevant sites. Future long-term studies should explore whether these BMD reductions translate into a greater fracture risk.

The use of photovoice to explore the physical disability experience in older adults with mild cognitive impairment/early dementia.

Although co-occurring cognitive impairment and physical disability in older adults is common, there is little understanding of how this group perceives their ability to do their daily activities. This study used photovoice to explore how older adults with MCI/early dementia and physical disability without and with care partners (dyads) perceive challenges with their daily activities. Photovoice is a visual research methodology to capture participants' insight on aspects of their daily lives. No known studies have taken this approach to explore the experiences of older adults with MCI/early dementia and co-occurring physical disability. We used a cross-sectional, exploratory research design to understand participants' (n = 12) experiences in their home environment. Photos and participant thoughts on the photos were categorized based on the Blackfoot Breath of Life Theory and the Hierarchy Model of Needs in Dementia, an adaptation of Maslow's Model. Notable findings included: awareness of physical/cognitive difficulties by older adults, solutions for ADL difficulty in persons with MCI/early dementia, care partners' difficulty recognizing pain without the presence of severe emotional or physical responses, reducing mood severity, and self-esteem needs met with structured, memory-issue adapted, meaningful activities. Older adults with co-occurring physical disability and MCI/early dementia identified both physiological and psychological needs despite challenges impacting their cognition. Photovoice evoked daily situations of these individuals and revealed the importance of developing individualized intervention elements for older adults with dementia and physical disability.

Development and validation of Physical Disability Index and Mental Disability Index and their associations with falls among older adults.

BACKGROUND: To enhance the precision of measuring, analyzing, and forecasting care needs for older adults with physical and/or mental disabilities, we developed the Physical Disability Index (PDI) and Mental Disability Index (MDI). Furthermore, we evaluated the reliability and validity of the PDI and MDI. Additionally, we investigate their associations with falls to further indicate the predictive validity. METHODS: A total of 11,621 older adults (53.1% women; mean age=83.2; SD=10.8) from 23 provinces in China were investigated in 2017-2018 to assess the reliability and validity of the PDI and MDI among older adults aged 65 to 105. Among which, 6,071 older adults with both baseline (2017-2018) and follow-up (2021) data were included in analyses to evaluate associations between the baseline health status determined by PDI and MDI and the number and severity of falls at baseline and follow-up. Cronbach's alpha was used to determine internal consistency. The convergent and divergent validity, known-group validity and concurrent validity were assessed. Multinomial logistic regression models were utilized to assess associations. RESULTS: We found satisfactory internal consistency (Cronbach's alpha ≥0.70) of the PDI and MDI in the total sample and sex-specific subgroups. Our results support the convergent and divergent validity, known-group validity, and concurrent validity of the PDI and MDI. We also found baseline physical disability and comorbid physical and mental disability are associated with a higher risk of baseline and follow-up falls. CONCLUSIONS: The PDI and MDI are reliable and valid instruments to assess physical and mental disability status among older adults respectively.

Krill oil supplementation for knee pain: a systematic review and meta-analysis with trial sequential analysis of randomized controlled trials.

INTRODUCTION: Knee pain is a major cause of disability worldwide, particularly among the elderly. Current treatments, including nonsteroidal anti-inflammatory drugs and analgesics, often lead to adverse effects. Krill oil is being explored as a potential alternative, however its efficacy in managing knee symptoms remains unclear. METHODS: MEDLINE, Embase, and Cochrane databases were searched until May 2024 for studies comparing krill oil and placebo in knee pain patients. Endpoints included knee pain, stiffness, physical function, and lipid profiles (HDL-C, LDL-C, triglycerides, and total cholesterol). A restricted maximum likelihood random-effects model with standardized mean differences (SMD) and 95% confidence intervals (CI) was used. A trial sequential analysis was conducted to evaluate further research implications. RESULTS: We included five trials with 700 patients using krill oil for knee pain. Results showed no significant difference between krill oil and placebo for knee pain, knee stiffness, and lipid profiles. However, krill oil demonstrated a significant small effect in improving knee physical function (SMD -0.24, 95% CI [-0.41; -0.08], I2 = 0%).Trial sequential analysis provided certainty that krill oil enhances knee physical function compared to placebo and indicated no improvement in knee pain, but the findings for knee stiffness need to be confirmed by further research. CONCLUSION: This study found that krill oil supplementation did not significantly improve knee pain, stiffness, or lipid profile, although it may help knee physical function. Based on these findings, krill oil supplementation is not yet justified for knee pain.

Effects of a telehealth-delivered Mediterranean diet intervention in adults with Rheumatoid Arthritis (MEDRA): a randomised controlled trial.

OBJECTIVE: To compare the effects a Mediterranean diet (MedDiet) versus the Irish Healthy Eating Guidelines (HEG) on physical function and quality of life in adults with rheumatoid arthritis (RA) in Ireland. METHODS: Forty-four adults with RA were randomised (1:1) to the MedDiet or HEG for 12 weeks. The intervention included three video teleconsultations and two follow-up telephone calls facilitated by a Registered Dietitian (RD). Changes in physical function by Health Assessment Questionnaire- Disability Index (HAQ-DI) and quality of life by Rheumatoid Arthritis Quality of Life Questionnaire (RAQoL) were the primary outcomes measured. Secondary outcomes included changes in dietary adherence, physical activity by Yale Physical Activity survey (YPAS), patient-perceived pain and general health, and anthropometric measures. All measurements were administered at baseline and repeated at 6 and 12 weeks. RESULTS: Forty participants completed the study. Participants were primarily females (87.5%), mean age was 47.5 ± 10.9 years. At the end of the intervention, participants in the MedDiet group reported significantly better physical function (p = 0.006) and quality of life (p = 0.037) compared to HEG group. From baseline to 12 weeks, physical function significantly improved in both diet groups, MedDiet (0.9 ± 0.5 to 0.5 ± 0.4 units, p < 0.001) and HEG (1.4 ± 0.7 to 1.0 ± 0.6 units, p < 0.001). Quality of life also significantly improved in the MedDiet (10.1 ± 7.5 to 4.0 ± 4.7 units, p < 0.001) and HEG group (11.25 ± 7.2 to 7.9 ± 6.4 units, p = 0.048). Physical activity improved significantly in the MedDiet (56.7 ± 28.6 to 70.6 ± 33.5 points, p = 0.01) but not within the HEG group despite similar recommendations. CONCLUSION: Adhering to the MedDiet and Irish Healthy Eating Guidelines resulted in improvements in RA patient-reported outcomes. The changes observed in both diet groups are likely due to the improvement in overall diet quality irrespective of dietary prescription. TRIAL REGISTRATION NUMBER: NCT04262505.

Longitudinal Decline of Exercise Capacity in Male and Female Mice.

The population of older adults is exponentially expanding. Alongside aging comes the onset of chronic disease, decline of functional capacity, and reduced quality of life. Thus, this population increase will stress the capacity and financial viability of health and long-term care systems. Developing pre-clinical models for age-related functional decline is imperative to advancing therapies that extend healthspan and prolong independence. Previously in a cross-sectional study, we established a powerful composite scoring system we termed CFAB (comprehensive functional assessment battery). CFAB measures physical function and exercise capacity using well-validated determinants to measure overall motor function, fore-limb strength, four-limb strength/endurance, aerobic capacity, and volitional exercise/activity rate. In the current work, we used CFAB to track cohorts of male and female C57BL/6 mice over the lifespan (measuring CFAB at 6, 12, 18, 24, and 28 months of age). Overall, we found statistically significantly declining function as the mice aged, with some differences between males and females in trajectory and slope. We also determined that body mass changes presented differently between sexes, and tracked body composition (fat percentage, using magnetic resonance imagery) in females. In a subset of mice, we tracked in vivo contractile physiology noting declines in plantar flexor maximum isometric torque. In summary, our data suggest that males and females declined at different rates. We confirmed the efficacy of CFAB to track longitudinal changes in exercise capacity and physical fitness in both males and females, further validating the system to track age-related functional decline.

Association between Cognitive Function and Physical Function, Frailty, and Quality of Life in Older Breast Cancer Survivors.

BACKGROUND: Older cancer survivors in general are at greater risk for cancer-related cognitive impairment (CRCI), yet few studies have explored its association with health outcomes. This study examined the association between subjective and objective measures of cognitive function and physical function, frailty, and quality of life (QoL) among older breast cancer survivors. MATERIALS AND METHODS: Older breast cancer survivors who reported cognitive concerns completed surveys on patient-reported cognitive function, physical function, frailty, and QoL as well as objective tests of visuospatial working memory and sustained attention. Data were analyzed using descriptive statistics and separate linear regression models. RESULTS: A total of 219 female breast cancer survivors completed the study. Perceived cognitive abilities were associated with better physical function, frailty, and QoL (p ≤ 0.001) while cognitive concerns were negatively related with these metrics (p ≤ 0.001). Poorer visuospatial working memory and sustained attention were linked to increased frailty (p ≤ 0.001-0.01), whereas poorer sustained attention was associated with poorer physical function (p < 0.01). CONCLUSIONS: Older breast cancer survivors with perceived cognitive impairment and poorer cognitive performance reported poorer physical functioning, increased frailty, and poorer QoL. These findings underscore the importance of assessing cognitive concerns and their associated outcomes in older breast cancer survivors.

Telehealth-Supported Exercise or Physical Activity Programs for Knee Osteoarthritis: Systematic Review and Meta-Analysis.

BACKGROUND: The integration of telehealth-supported programs in chronic disease management has become increasingly common. However, its effectiveness for individuals with knee osteoarthritis (KOA) remains unclear. OBJECTIVE: This study aimed to assess the effectiveness of telehealth-supported exercise or physical activity programs for individuals with KOA. METHODS: A comprehensive literature search encompassing Embase, MEDLINE, CENTRAL, Web of Science, PubMed, Scopus, PEDro, GreyNet, and medRxiv from inception to September 2023 was conducted to identify randomized controlled trials comparing telehealth-supported exercise or physical activity programs to a control condition for KOA. Data were extracted and qualitatively synthesized across eligible studies, and a meta-analysis was performed to evaluate the effects. The study was reported according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020. RESULTS: In total, 23 studies met eligibility criteria, with 20 included in the meta-analysis. Results showed that telehealth-supported exercise or physical activity programs reduced pain (g=-0.39; 95% CI -0.67 to -0.11; P<.001), improved physical activity (g=0.13; 95% CI 0.03-0.23; P=.01), and enhanced physical function (g=-0.51; 95% CI -0.98 to -0.05; P=.03). Moreover, significant improvements in quality of life (g=0.25; 95% CI 0.14-0.36; P<.001), self-efficacy for pain (g=0.72; 95% CI 0.53-0.91; P<.001), and global improvement (odds ratio 2.69, 95% CI 1.41-5.15; P<.001) were observed. However, self-efficacy for physical function (g=0.14; 95% CI -0.26 to 0.53; P=.50) showed insignificant improvements. Subgroup analyses based on the World Health Organization classification of digital health (pain: χ22=6.5; P=.04 and physical function: χ22=6.4; P=.04), the type of teletechnology in the intervention group (pain: χ24=4.8; P=.31 and function: χ24=13.0; P=.01), and active or inactive controls (pain: χ21=5.3; P=.02 and physical function: χ21=3.4; P=.07) showed significant subgroup differences. CONCLUSIONS: Telehealth-supported exercise or physical activity programs might reduce knee pain and improve physical activity, physical function, quality of life, self-efficacy, and global improvement in individuals with KOA. Future research should consider longer implementation durations and assess the feasibility of incorporating wearables and standardized components into large-scale interventions to evaluate the effects.

Sex differences in the association of physical functions with hospitalization and mortality events among community-dwelling older adults with disabilities.

This study aimed to investigate the role of sex in the association between physical function and the occurrence of hospitalization and mortality among community-dwelling older adults with impairments in activities of daily living (ADL). Participants included community-dwelling older adults aged ≥65 years with ADL disabilities. Physical functions (hand grip strength [HGS], knee extension muscle strength, and comfortable walking speed [CWS]) were measured at baseline and analyzed for association with hospitalization and mortality by sex using Cox regression analysis, adjusted for potential confounders. In this Cox regression analysis, HGS was significantly associated with the occurrence of hospitalization and mortality in women, whereas CWS was significantly associated with the occurrence of hospitalization and HGS with mortality in men. These findings reveal that the predictive ability of adverse events in community-dwelling older adults with disabilities differs by sex, requiring outcome- and sex-specific prognostication.

Yoga and Physical Therapy for Chronic Pain and Opioid Use Disorder Onsite in an Opioid Treatment Program: A Randomized Controlled Trial.

BACKGROUND: There is a lack of integrated treatment for chronic pain and opioid use disorder (OUD). Yoga and physical therapy (PT) may improve pain and physical function of people living with (PLW) chronic low back pain (CLBP) and may also reduce opioid craving and use, but PLW with OUD face barriers to accessing these interventions. We hypothesize that compared to treatment as usual (TAU), providing yoga and PT onsite at opioid treatment programs (OTPs) will be effective at improving pain, opioid use, and quality of life among people with CLBP and OUD, and will be cost-effective. METHODS: In this hybrid type-1 effectiveness-implementation study, we will randomly assign 345 PLW CLBP and OUD from OTPs in the Bronx, NY, to 12 weeks of onsite yoga, onsite PT, or TAU. Primary outcomes are pain intensity, opioid use, and cost-effectiveness. Secondary outcomes include physical function and overall well-being. DISCUSSION: This trial tests an innovative, patient-centered approach to combined management for pain and OUD in real-world settings. We rigorously examine the efficacy of yoga and PT onsite at OTPs as nonpharmacologic, cost-effective treatments among people with CLBP and OUD who face barriers to integrated care.

Walking and balance in older adults with age-related hearing loss: A cross-sectional study of cases and matched controls.

BACKGROUND: Hearing loss (HL) is prevalent in older individuals. It is suggested that there is an association between age-related HL, walking and balance, leading to poorer function and increased risk of falls in older individuals. RESEARCH QUESTION: Is HL associated with physical performance, gait variability, and postural sway in older adults, and will additional dizziness moderate the effect of HL on balance? METHODS: In this cross-sectional study we examined 100 older individuals (age ≥70 years, 60 % females), divided in two groups, with or without age-related HL. Physical function and balance were evaluated by the Short Physical Performance Battery (SPPB), postural sway measured on a force platform (posturography), and balance in walking (gait variability) measured with a body-worn sensor. Multiple linear regression was used to examine the relationships between the variables, with physical function and balance as outcomes and HL as a dichotomous exposure (>30 dB). For all analyses, we further tested if associations were modified by self-reported dizziness. RESULTS: Multiple regression analysis with HL, age, sex, education, diabetes, and cardiovascular disease revealed a significant association between reduced SPPB and HL. Multiple linear regression analysis also showed that HL was associated with increased postural sway on firm surface with eyes open and closed after adjusting for age, sex, education, diabetes, and cardiovascular disease. There was significant association between HL and increased gait variability during dual task walking in all directions after adjusting for age, sex, education, diabetes, and cardiovascular disease. Further, we found that the association between HL and SPPB was significantly stronger in those with dizziness compared with those without dizziness. Dizziness also modified the association of HL with the other SPPB sub-scores but not for the other outcomes of postural sway or gait variability. SIGNIFICANCE: In this study, age-related HL was associated with worse physical performance as measured by SPPB, postural sway, and gait variability. This relationship illustrates the importance of assessing physical performance in people with HL to prevent risk of falls and disability.

Declined intrinsic capacity predicts long-term mortality in Chinese older adults: Beijing Longitudinal Study of Aging.

BACKGROUND: Intrinsic capacity reflects an individual's functions and capacities across their lifetime. There are few studies on whether the level of intrinsic capacity can predict long-term mortality in Chinese populations. OBJECTIVE: To explore the effects of intrinsic capacity on long-term outcomes in older Chinese adults. METHODS: Data were obtained from the Beijing Longitudinal Study of Aging. Overall, 1699 community-dwelling adults aged ≥60 years were included and followed up for 8 years. Intrinsic capacity was determined according to the World Health Organization definition. The predictive ability for adverse outcomes was assessed using the age- and sex-adjusted Cox proportional hazards model. RESULTS: A decline in intrinsic capacity domains was observed in 729 (42.9 %) participants. Declines in the mobility, cognition, vitality, sensory and psychology domains were observed in 21.8 %, 15.1 %, 11.4 %, 9.10 %, and 14.2 % of the participants, respectively. Low intrinsic capacity was associated with worse physical performance, frailty, social frailty, chronic diseases, fracture, and falls. A greater decline in intrinsic capacity predicted an elevated 8-year mortality rate (decline in overall intrinsic capacity hazard ratio 2.91, 95 % confidence interval 2.44-3.47, P < 0.001; decline in one domain hazard ratio 2.11, 95 % confidence interval 1.71-2.61, P < 0.001; decline in two domains hazard ratio 3.54, 95 % confidence interval 2.81-4.45, P < 0.001; decline in three or more domains hazard ratio 5.30, 95 % confidence interval 4.09-6.87, P < 0.001); adjusted models did not affect prediction performance. Among the five domains of intrinsic capacity, cognition was the strongest predictor of mortality (hazard ratio 3.17, 95 % confidence interval 2.63-3.81, P < 0.001). CONCLUSIONS: Intrinsic capacity is useful in identifying older adults at higher risk of adverse outcomes, presenting significant implications for healthcare policies in China.

Evidence mapping and quality assessment of systematic reviews on exercise intervention for Alzheimer's disease.

BACKGROUND: A significant body of literature suggests that exercise can reverse cognitive impairment and ameliorate somatic function in patients with Alzheimer's disease (AD). Systematic reviews (SRs), a common approach of evidence-based medicine, concentrate on a specific issue of a research area. The objective of this work is to provide an overview of existing evidence on the effects of exercise intervention in AD patients and report related health outcomes by reviewing SRs. METHODS: SRs on exercise intervention in AD patients were retrieved from the PubMed, the Cochrane Library, CBMdisc, Scopus, Web of Science, Embase (via Ovid), China National Knowledge Infrastructure, and WanFang databases from the time of inception to February 2023. The quality of the SRs was evaluated utilizing the A Measurement Tool to Assess Systematic Review 2 (AMSTAR 2) checklist. The results were reported according to the population-intervention-comparison-outcome (PICO) framework and the corresponding evidence mapping was illustrated in tables and bubble plots. RESULTS: A total of 26 SRs met the eligibility criteria. In terms of methodological quality, 10 SRs were rated as "critically low", 13 SRs were rated as "low", and 3 SRs were rated as "moderate". Exercise was found to exert a beneficial effect on cognitive function, functional independence, physical function, and neuropsychiatric symptoms in patients with AD. CONCLUSION: Exercise intervention benefits AD patients mainly by improving cognitive function, physical function, functional independence, and neuropsychiatric symptoms. However, due to the low-to-moderate methodology of most SRs included in this analysis, further investigations are required to support our current findings.

Examination of Physical Functions, Activity and Participation in Children with Juvenile Idiopathic Arthritis.

AIMS: To examine physical functions, activity, and participation level, and associated factors with participation in children with juvenile idiopathic arthritis (JIA) across the International Classification of Functioning Disability and Health-Children and Youth. METHODS: 49 children (Girl/Boy:28/21) aged between 7 and 18 years (Mean: 13.4 ± 3.3) were included. To evaluate body structure/functioning; pain, fatigue, disease activity, and motor functions were assessed. Childhood Health Assessment Questionnaire and Juvenile Arthritis Biopsychosocial and Clinical Questionnaire were used to determine activity level. Child and Adolescent Scale of Participation was used to assess participation. RESULTS: Mild level of pain (2.0 ± 2.3), disease activity (2.0 ± 2.3), and fatigue (4.1 ± 4.0) were recorded. Decrease in motor functions was determined in 75% of children, while 61% of whom had activity-related disability. There was mild to moderate participation restrictions, and participation was significantly associated with age (r = -0.29), pain severity (r = -0.31), disease activity (r = -0.39), motor functions (r = 0.33), and activity level (r = -0.43), (p Ë‚ 0.05). CONCLUSIONS: Majority of children with JIA have deteriorations in physical functions, activity, and participation. Age, pain, disease activity, motor functions and activity level were associated with participation level. Children with JIA should be regularly evaluated multi-directional and they should be referred to rehabilitation programs to increase functionality and participation.

Establishing minimal clinically important differences and patient acceptable symptom state thresholds following birmingham hip resurfacing.

INTRODUCTION: Birmingham Hip Resurfacing (BHR) has emerged as a compelling and innovative alternative to total hip arthroplasty (THA), especially among young, active patients. However, the Minimal Clinically Important Difference (MCID) and the Patient Acceptable Symptom State (PASS) thresholds have not yet been determined for patients undergoing BHR. Therefore, the current study aimed to (1) determine the MCID and PASS thresholds for both the Hip disability and Osteoarthritis Outcome Score (HOOS)-Pain and HOOS physical function shortform (PS), for patients who underwent BHR; and (2) identify factors influencing the achievement of MCID and PASS for HOOS-Pain and HOOS-PS. METHODS: Prospectively collected data from patients undergoing BHR was analyzed. Patients with osteoarthritis and completed preoperative and 1-year postoperative PROMs were included. Distribution-based and anchored-based approaches were used to estimate MCID and PASS, respectively. The optimal cut-off point for PASS thresholds was calculated using the Youden index. RESULTS: MCID for HOOS-Pain and PS were calculated to be 9.2 and 9.3, respectively. The PASS threshold for HOOS-Pain and PS were ≥ 77.7 and ≥ 87.3, respectively. The current study identified several factors affecting postoperative achievement of thresholds. Baseline Mental Component Summary (MCS) scores were a predictor for achieving MCID for postoperative HOOS-Pain, achieving MCID for postoperative HOOS-PS, achieving PASS for postoperative HOOS-Pain, and achieving PASS for postoperative HOOS-PS. Furthermore, baseline HOOS-Pain was a significant predictor for achieving MCID for postoperative HOOS-PS, achieving PASS for postoperative HOOS-Pain, and achieving PASS for postoperative HOOS-PS. CONCLUSIONS: MCID and PASS thresholds were established for HOOS-Pain and PS domains following BHR with most patients achieving these clinically meaningful benchmarks. Additionally, several factors affecting achievement of MCID and PASS were identified, including modifiable risk factors that may allow clinicians to implement optimization strategies and further improve outcomes.

High physical activity is associated with greater cortical bone size, better physical function, and with lower risk of incident fractures independently of clinical risk factors in older women from the SUPERB study.

The Physical Activity Scale for the Elderly (PASE) is a validated test to assess physical activity in older people. It has not been investigated if physical activity, according to PASE, is associated with fracture risk independently from the clinical risk factors (CRFs) in FRAX, bone mineral density (BMD), comorbidity, and if such an association is due to differences in physical performance or bone parameters. The purpose of this study was to evaluate if PASE score is associated with bone characteristics, physical function, and independently predicts incident fracture in 3014 75-80-year-old women from the population-based cross-sectional SUPERB study. At baseline participants answered questionnaires, and underwent physical function tests, detailed bone phenotyping with dual x-ray absorptiometry, and high-resolution peripheral quantitative computed tomography. Incident fractures were x-ray verified. Cox regression models were used to assess the association between PASE score and incident fractures, with adjustments for CRFs, FN BMD and Charlson comorbidity index. Women were divided into quartiles according to PASE score. Quartile differences in bone parameters (1.56% for cortical volumetric BMD and 4.08% for cortical area, Q4 vs. Q1, p = 0.007 and p = 0.022, respectively) were smaller than quartile differences in physical performance (27% shorter timed up and go test, 52% longer one leg standing time, Q4 vs. Q1). During 8 years (median, range 0.20-9.9) of follow-up, 1077 women had any fracture, 806 a major osteoporotic fracture (MOF; spine, hip, forearm, humerus), and 236 a hip fracture. Women in Q4 had 30% lower risk of any fracture, 32% lower risk of MOF, and 54% lower risk of hip fracture, compared to women in Q1. These associations remained in fully adjusted models. In conclusion, high physical activity was associated with substantially better physical function and a lower risk of any fracture, MOF and hip fracture, independently of risk factors used in FRAX, FN BMD and comorbidity.

The Physical Activity Scale for the Elderly (PASE) is a test to assess physical activity in older people. The purpose of this study was to evaluate if physical activity, according to PASE, is associated with bone parameters, physical function, and independently predicts future fracture in 3014 75­80-year-old women from the population-based SUPERB study. At baseline participants answered questionnaires, underwent physical function tests and dual x-ray absorptiometry. Subsequent fractures were x-ray verified. Women were divided into quartiles according to PASE score (Q1 least and Q4 most physically active). Women in Q4 had 27% shorter timed up and go test and 52% longer one leg standing time compared with Q1. During 8 years of follow-up, 1077 women had any fracture, 806 a major osteoporotic fracture (MOF; spine, hip, forearm, humerus), and 236 a hip fracture. Women in Q4 had 30% lower risk of any fracture, 32% lower risk of MOF, and 54% lower risk of hip fracture, compared to women in Q1. These associations remained in models considering comorbidity, bone mineral density and clinical risk factors. In conclusion, high physical activity was independently associated with better physical function and a lower risk of any fracture.

Community-based exercises improve health status in pre-frail older adults: A systematic review with meta-analysis.

BACKGROUND: Pre-frailty is associated with increased healthcare utilization. Over the past decade, public health interventions such as community-based exercises to target pre-frailty have been increasingly studied. However, the effects of community-based exercises on clinical outcome measures amongst community-dwelling older adults with pre-frailty remain unclear. This review aims to better understand the effects of community-based exercise on physical function, cognition, quality of life and frailty status in community-dwelling pre-frail older adults. A secondary objective was to investigate the optimal exercise parameters on clinical outcomes. METHODS: Searches of MEDLINE, CINAHL, Google Scholar and Web of Science databases were conducted. Articles were included if they were randomized controlled trials (RCTs), and excluded if the participants consist of less than 50% pre-frail community-dwelling older adults. Meta-analyses (where possible) with either a fixed- or random- effect(s) model, standardized mean difference (SMD), odds ratio (OR) and tests of heterogeneity were performed. Multivariable meta-regression was performed to identify predictors of statistically significant outcome measures. The risk of bias was assessed using the modified Cochrane Risk-of-Bias tool. RESULTS: Twenty-two RCTs with 900 participants in the experimental group and 1015 participants in the control group were included. When compared to minimal intervention, community-based exercises significantly improved lower limb strength (10 RCTs, 384 participants in the experimental group and 482 participants in the control group) with SMD 0.67 (95% CI 0.29 to 1.04), and lower limb function (5 RCTs, 120 participants in the experimental group and 219 participants in the control group) with SMD 0.27 (95% CI 0.03 to 0.51). Those who have received community-based exercises were more likely to reverse from pre-frailty to healthy state (OR = 2.74, 95% CI 1.36 to 5.51) (6 RCTs, 263 participants in the experimental group and 281 participants in the control group). The frequency of exercise sessions was a significant predictor of the effect size for gait speed (P<0.05). CONCLUSIONS: Community-based exercise intervention is superior to minimal intervention for improving health status in pre-frail older adults. This has implications on the implementation of community-based exercise intervention by healthcare providers and policymakers. OTHER: Nil funding for this review.
