Background Physiotherapy has emerged as an important health strategy to deliver lifestyle, exercise and physical activity for people with knee osteoarthritis. However, little is known about the extent to which physiotherapists adhere to clinical practice guidelines. This study aimed to explore the perspectives and care patterns of physiotherapists in Sydney, Australia on their delivery of knee osteoarthritis care and how this aligns with the 2019 Osteoarthritis Research Society International (OARSI) guidelines. Methods We invited thirty-three physiotherapists from nine private practices in metropolitan Sydney to partake in a semi-structured interview. The interviews were digitally recorded and transcribed verbatim. The data collected were analysed deductively using content analysis, comparing guidelines to current care patterns, while their perspectives were inductively analysed through thematic analysis. Results Thirty physiotherapists participated (age range 22–63 years, 17 male and 13 female). Interview responses indicated that most physiotherapists were satisfied with their care of knee osteoarthritis patients. Most physiotherapists delivered “core” guideline-based care of education and land-based exercise. Recommendations of modalities of exercise, including hydrotherapy and manual therapy, were discussed and were perceived to be beneficial despite not being “core” clinical guideline recommendations. Current treatment strategies focussed on disease severity, symptom presentation and/or patient exercise history with little emphasis on education about osteoarthritis pathophysiology and drug-based pain relief. The thematic analysis identified two over-arching themes; (1) capacity to deliver and awareness of evidence-based care and (2) perceived recommendations for future physiotherapy management. Participants identified notable areas of potential service improvement including developing stronger and more effective reimbursement models, increased consult times and improved patient access. Conclusion The study provided unique insights towards physiotherapists’ current usual knee osteoarthritis care and their perceived barriers to delivering guideline-based care. Thus, informing a need for future studies to focus on developing specific and detailed guidelines if physiotherapists are to align more closely to the core guideline-based recommendations. Trial registration This study was part of a larger study, with the full protocol published and registered at ClinicalTrials (ACTRN12620000188932, ACTRN12620000218998) 19/02/2020).

ObjectivesDiet and physical activity are crucial for people with chronic kidney disease (CKD) to maintain good health. Digital health interventions can increase access to lifestyle services. However, consumers’ perspectives are unclear, which may reduce the capacity to develop interventions that align with specific needs and preferences. Therefore, this review aims to synthesise the preferences of people with CKD regarding digital health interventions that promote healthy lifestyle.DesignQualitative systematic review with meta-ethnography.Data sourcesDatabases Scopus, CENTRAL, MEDLINE, CINAHL and SPORTDiscus were searched between 2000 and 2023.Eligibility criteriaPrimary research papers that used qualitative exploration methods to explore the preferences of adults with CKD (≥18 years) regarding digital health interventions that promoted diet, physical activity or a combination of these health behaviours.Data extraction and synthesisTwo independent reviewers screened title, abstract and full text. Discrepancies were resolved by a third reviewer. Consumers’ quotes were extracted verbatim and synthesised into higher-order themes and subthemes.ResultsDatabase search yielded 5761 records. One record was identified following communication with a primary author. 15 papers were included. These papers comprised 197 consumers (mean age 51.0±7.2), including 83 people with CKD 1–5; 61 kidney transplant recipients; 53 people on dialysis. Sex was reported in 182 people, including 53% male. Five themes were generated regarding consumers’ preferences for digital lifestyle interventions. These included simple instruction and engaging design; individualised interventions; virtual communities of care; education and action plans; and timely reminders and automated behavioural monitoring.ConclusionDigital health interventions were considered an important mechanism to access lifestyle services. Consumers’ preferences are important to ensure future interventions are tailored to specific needs and goals. Future research may consider applying the conceptual framework of consumers’ preferences in this review to develop and evaluate the effect of a digital lifestyle intervention on health outcomes.PROSPERO registration numberCRD42023411511.

Purpose This study aimed to understand perceptions that knee osteoarthritis patients have regarding their experiences of guideline-based recommendations within their care received from physiotherapists in private practice. Methods A qualitative semi-structured interview study nested within a larger trial auditing care provided by physiotherapists. Recruited adults ≥ 45 years with knee osteoarthritis across nine primary care physiotherapy practices. Interview questions were anchored around the core elements recommended in guidelines for the management of knee osteoarthritis and patient perceptions of these were analysed using both content and thematic qualitative analysis approaches. Patient satisfaction with care received was asked at the time of interview. Results Twenty-six patients volunteered for the study (mean 60 years, 58% female). Analysis identified that physiotherapists focused on treating symptoms through quadriceps strengthening exercises, which patients found to be effective, though focussed less on other aspects of evidenced-based care. Patient’s perceived treatment to be effective in relieving pain and enabling them to stay active and they appreciated the positive role that their physiotherapist provided in alleviating their concerns. Overall, patients were satisfied with their physiotherapy care but would have liked more specific osteoarthritis education and longer-term management. Conclusion The description of the physiotherapy-related care received by people with knee osteoarthritis aligns with guideline recommendations, though mainly for strength-related exercise prescription. Despite some perceived shortfalls in care, patients do appear to be satisfied. However, improvements in patient outcomes may be possible if more elements of guideline-base care are regularly provided, including enhancing osteoarthritis education and fostering behaviour change.

Background People with different types of dementia may have distinct symptoms and experiences that affect their quality of life. This study investigated whether quality of life varied across types of dementia and over time. Methods The participants were 1555 people with mild-to-moderate dementia and 1327 carers from the IDEAL longitudinal cohort study, recruited from clinical services. As many as possible were followed for up to 6 years. Diagnoses included were Alzheimer’s disease, vascular dementia, mixed Alzheimer’s and vascular dementia, Parkinson’s disease dementia, dementia with Lewy bodies, and frontotemporal dementia. Self- and informant-rated versions of the Quality of Life in Alzheimer’s Disease scale were used. A joint model, incorporating a mixed effects model with random effects and a survival model to account for dropout, was used to examine whether quality of life varied by dementia type at the time of diagnosis and how trajectories changed over time. Results The strongest associations between dementia type and quality of life were seen around the time of diagnosis. For both self-ratings and informant ratings, people with Parkinson’s disease dementia or dementia with Lewy bodies had lower quality of life scores. Over time there was little change in self-rated scores across all dementia types (− 0.15 points per year). Informant-rated scores declined over time (− 1.63 points per year), with the greatest decline seen in ratings by informants for people with dementia with Lewy bodies (− 2.18 points per year). Conclusions Self-rated quality of life scores were relatively stable over time whilst informant ratings showed a steeper decline. People with Parkinson’s disease dementia or dementia with Lewy bodies report particularly low levels of quality of life, indicating the importance of greater attention to the needs of these groups.

Objectives Longitudinal evidence documenting health conditions in spousal caregivers of people with dementia and whether these influence caregivers’ outcomes is scarce. This study explores type and number of health conditions over two years in caregivers of people with dementia and subgroups based on age, sex, education, hours of care, informant-rated functional ability, neuropsychiatric symptoms, cognition of the person with dementia, and length of diagnosis in the person with dementia. It also explores whether over time the number of health conditions is associated with caregivers’ stress, positive experiences of caregiving, and social networks Methods Longitudinal data from the IDEAL (Improving the experience of Dementia and Enhancing Active Life) cohort were used. Participants comprised spousal caregivers ( n  = 977) of people with dementia. Self-reported health conditions using the Charlson Comorbidity Index, stress, positive experiences of caregiving, and social network were assessed over two years. Mixed effect models were used Results On average participants had 1.5 health conditions at baseline; increasing to 2.1 conditions over two years. More health conditions were reported by caregivers who were older, had no formal education, provided 10 + hours of care per day, and/or cared for a person with more neuropsychiatric symptoms at baseline. More baseline health conditions were associated with greater stress at baseline but not with stress over time. Over two years, when caregivers’ health conditions increased, their stress increased whereas their social network diminished Discussion Findings highlight that most caregivers have their own health problems which require management to avoid increased stress and shrinking of social networks

Background Most people with dementia have multiple health conditions. This study explores (1) number and type of health condition(s) in people with dementia overall and in relation to age, sex, dementia type, and cognition; (2) change in number of health conditions over two years; and (3) whether over time the number of health conditions at baseline is related to social isolation, loneliness, quality of life, and/or well-being. Methods Longitudinal data from the IDEAL (Improving the experience of Dementia and Enhancing Active Life) cohort were used. Participants comprised people with dementia ( n  = 1490) living in the community (at baseline) in Great Britain. Health conditions using the Charlson Comorbidity Index, cognition, social isolation, loneliness, quality of life, and well-being were assessed over two years. Mixed effects modelling was used. Results On average participants had 1.8 health conditions at baseline, excluding dementia; increasing to 2.5 conditions over two years. Those with vascular dementia or mixed (Alzheimer’s and vascular) dementia had more health conditions than those with Alzheimer’s disease. People aged ≥ 80 had more health conditions than those aged < 65 years. At baseline having more health conditions was associated with increased loneliness, poorer quality of life, and poorer well-being, but was either minimally or not associated with cognition, sex, and social isolation. Number of health conditions had either minimal or no influence on these variables over time. Conclusions People with dementia in IDEAL generally had multiple health conditions and those with more health conditions were lonelier, had poorer quality of life, and poorer well-being.

Background Cross-sectional evidence indicates that certain personality traits may influence how well people with dementia and their caregivers are able to live alongside the condition. However, no studies to date have explored these associations longitudinally. The present study aimed to explore whether each of the Five-Factor personality traits were associated with change over two years in perceptions of ‘living well’ for people with dementia and their caregivers. ‘Living well’ was conceptualized as a composite of quality of life, satisfaction with life, and subjective well-being. Methods Data were analyzed from 1487 people with dementia and 1234 caregivers who took part in the IDEAL cohort. Participants were categorized into low, medium, and high groups for each trait using stanine scores. Latent growth curve models investigated associations between these groups and ‘living well’ scores for each trait at baseline and at 12 and 24 months. Covariates included cognition in people with dementia and stress in caregivers. A Reliable Change Index was calculated against which to evaluate changes in ‘living well’ scores over time. Results At baseline, neuroticism was negatively associated with ‘living well’ scores for people with dementia, while conscientiousness, extraversion, openness, and agreeableness were positively associated. For caregivers, neuroticism was negatively associated with ‘living well’ scores at baseline while conscientiousness and extraversion were positively associated. ‘Living well’ scores were mostly stable over time with no influence of personality traits on observed changes. Conclusions Findings suggest that personality traits, particularly neuroticism, have a meaningful impact on how people with dementia and caregivers rate their capability to ‘live well’ at baseline. Over time ‘living well’ scores for each personality trait group were largely stable. Studies utilizing longer follow-up periods and more appropriate measures of personality are needed to corroborate and extend the findings of the present study.

Current policy emphasises the importance of ‘living well’ with dementia, but there has been no comprehensive synthesis of the factors related to quality of life (QoL), subjective well-being or life satisfaction in people with dementia. We examined the available evidence in a systematic review and meta-analysis. We searched electronic databases until 7 January 2016 for observational studies investigating factors associated with QoL, well-being and life satisfaction in people with dementia. Articles had to provide quantitative data and include ⩾75% people with dementia of any type or severity. We included 198 QoL studies taken from 272 articles in the meta-analysis. The analysis focused on 43 factors with sufficient data, relating to 37639 people with dementia. Generally, these factors were significantly associated with QoL, but effect sizes were often small (0.1–0.29) or negligible (<0.09). Factors reflecting relationships, social engagement and functional ability were associated with better QoL. Factors indicative of poorer physical and mental health (including depression and other neuropsychiatric symptoms) and poorer carer well-being were associated with poorer QoL. Longitudinal evidence about predictors of QoL was limited. There was a considerable between-study heterogeneity. The pattern of numerous predominantly small associations with QoL suggests a need to reconsider approaches to understanding and assessing living well with dementia.

This study investigated the contribution of muscle architecture to the differences in the torque-velocity and power-velocity relationships between older (OM n = 9, aged 69-82 years) and younger men (YM n = 15, aged 19-35 years). Plantarflexors' (PF) maximal isometric and concentric torques were recorded at 0.87, 1.75, 2.62, 3.49 and 4.36 rad s(-1). Physiological cross-sectional area (PCSA) was calculated as the ratio of muscle volume (determined by magnetic resonance imaging) to muscle fascicle length (Lf, measured by ultrasonography). GM PCSA and Lf of the OM were, respectively, 14.3% (P < 0.05) and 19.3% (P < 0.05) smaller than of the YM. In the OM, GM maximum isometric torque and maximum contraction velocity (Vmax), estimated from Hill's equation were, respectively, 48.5 and 38.2% lower (P < 0.001) than in the YM. At all contraction velocities, the OM produced less torque than the YM (46.3% of YM at 0.87 rad s(-1) to 14.7% at 4.36 rad s(-1), P < 0.001). Peak power (PP) of the OM was 80% lower than that of the YM and normalisation of PP to muscle volume only reduced this difference by 10%. Normalisation of torque to PCSA reduced, but did not eliminate, differences in torque between YM and OM (9.6%) and differences in torque/PCSA increased with contraction velocity (P < 0.05). After normalisation of velocity to Lf, the difference in Vmax between the OM and the YM was reduced to 15.9%. Thus, although muscle architecture contributes significantly to the differences in the torque- and power-velocity properties of OM and YM, other contractile factors, intrinsic to the muscle, seem to play a role. It is noteworthy that the deficit in PP between OM and YM is far greater than that of muscle torque, even after normalisation of PP to muscle volume. This finding likely plays an important role in the loss of mobility in old age.

PurposeThe benefits of exercise across the lifespan and for a wide spectrum of health and diseases are well known. However, there remains less clarity as to the effects of both acute and chronic exercise on joint health. Serum biomarkers of joint metabolism are sensitive to change and have the potential to differentiate between normal and adverse adaptations to acute and chronic load. Therefore, the primary objective of this review is to evaluate how serum biomarkers can inform our understanding of how exercise affects joint metabolism.MethodsA comprehensive literature search was completed to identify joint biomarkers previously used to investigate acute and chronic exercise training.ResultsIdentified biomarkers included those related to joint cartilage, bone, synovium, synovial fluid, and inflammation. However, current research has largely focused on the response of serum cartilage oligomeric matrix protein (COMP) to acute loading in healthy young individuals. Studies demonstrate how acute loading transiently increases serum COMP (i.e., cartilage metabolism), which is mostly dependent on the duration of exercise. This response does not appear to be associated with any lasting deleterious changes, cartilage degradation, or osteoarthritis.ConclusionSeveral promising biomarkers for assessing joint metabolism exist and may in future enhance our understanding of the physiological response to acute and chronic exercise. Defining ‘normal’ and ‘abnormal’ biomarker responses to exercise and methodological standardisation would greatly improve the potential of research in this area to understand mechanisms and inform practice.
