Effectiveness and cost-effectiveness of a digital falls' prevention programme versus usual care to improve balance, falls risk and function in older adults: protocol for the KOKU randomised controlled trial

Background:Falls are the primary cause of fatal and non-fatal accidental injuries in older adults. The World Falls Prevention Guidelines recommend balance-challenging, functional exercise programmes as a key strategy for falls prevention but access, uptake and adherence to these programmes in community settings remain suboptimal. Keep-On-Keep-Up (KOKU), a digital, National Health Service (NHS) approved programme was co-developed with older adults and therapists, to provide progressive, evidence-based exercises and to raise awareness of fall prevention strategies.Objective:This trial aims to investigate the effectiveness and cost-effectiveness of the KOKU digital strength and balance programme for improving balance, enhancing physical function and reducing falls risk among community dwelling older adults.Methods:This is a two-arm, parallel group randomised controlled trial. A total of 196 community dwelling older adults aged 60 years and older will be randomised to either the intervention group comprising a digital strength and balance programme (KOKU) alongside standard care (strength and balance exercise advice and a falls prevention leaflet) or to a control group, receiving standard care only. Participants receiving the intervention will be asked to exercise three times per week following the tailored and progressive programme. Randomisation will take place after recruitment and baseline data collection. The trial’s primary outcome measure is balance function (Berg Balance Score) at twelve weeks post-randomisation. Secondary trial outcomes include: lower limb strength; healthcare utilisation and health-related quality of life; self-reported concerns about falling; self-reported physical activity; falls risk, pain, mood, fatigue, self-reported falls, acceptability and usability of the KOKU programme. Intention to treat analysis and a cost-effectiveness analysis will be employed for trial data analysis. Qualitative interviews and focus groups will be undertaken with around 10 care providers and 13 participants to further understand views of the intervention and trial processes.Results:This study began recruitment in July 2024 and concluded in March 2024 recruiting a total of 202 participants (102 intervention and 100 control). Following protocol publication, data compilation and analysis will be conducted, with results anticipated to be published in 2027.Conclusions:This trial will provide important evidence on whether a digital strength and balance programme can improve balance and related outcomes in older adults compared to usual care.

Fear-of-falling and associated risk factors in persons with rheumatoid arthritis: a 1 year prospective study

Abstract: Background: Falls, associated injuries and fear-of-falling are common in adults with RA. Fear-of-falling can be a major consequence of, and as debilitating as falling, resulting in a cycle of activity restriction, reduced quality of life, institutionalisation and potentially increase risk of falls. The objective of this study was to examine the relationship between fear-of-falling and risk factors associated with fear-of-falling in adults with rheumatoid arthritis (RA) over a 1 year period. Methods: Five hundred fifty-nine patients with RA were recruited from four outpatient clinics in this prospective cohort study. Baseline assessments included socio-demographic, medical and lifestyle related risk factors. Fall incidence was prospectively obtained monthly using postal cards over a 1 year period. Fear-of-falling was assessed at baseline and 1 year using the Short Falls Efficacy Scale-International (Short FES-I). Logistic regression was used to determine the association between high fear-of-falling (Short FES-I > 11) at baseline (outcome) and a range of putative predictor variables including previous falls, and also baseline factors associated with a high fear-of-falling at follow-up. Results: Five hundred thirty-five (ninety-six percent) participants (mean age 62.1 yrs.; 18–88 yrs) completed 1 year follow-up and of these, 254 (47%) completed the Short FES-I questionnaire at 1 year. In a multivariate model, a history of multiple falls (OR = 6.08) higher HAQ score (OR = 4.87) and increased time to complete the Chair Stand Test (OR = 1.11) were found to be independent predictors of high fear-of-falling and had an overall classification rate of 87.7%. There were no significant differences found in fear-of-falling at 1 year follow-up in those who reported falls during the study, participant’s baseline fear appeared to predict future fear, regardless of further falls. Conclusions: Fear-of-falling is significantly associated with previous falls and predictive of future falls and fear. RA patients would benefit from fall prevention measures whether or not they have previously fallen

A prospective cohort study measuring cost-benefit analysis of the Otago Exercise Programme in community dwelling adults with rheumatoid arthritis.

BACKGROUND: Falls are one of the major health problems in adults with Rheumatoid Arthritis (RA). Interventions, such as the Otago Exercise Programme (OEP), can reduce falls in community dwelling adults by up to 35%. The cost-benefits of such a programme in adults with RA have not been studied. The aims of this study were to determine the healthcare cost of falls in adults with RA, and estimate whether it may be cost efficient to roll out the OEP to improve function and prevent falls in adults living with RA. METHODS: Patients with Rheumatoid Arthritis aged ≥18 years were recruited from four rheumatology clinics across the Northwest of England. Participants were followed up for 1 year with monthly fall calendars, telephone calls and self-report questionnaires. Estimated medical cost of a fall-related injury incurred per-person were calculated and compared with OEP implementation costs to establish potential economic benefits. RESULTS: Five hundred thirty-five patients were recruited and 598 falls were reported by 195 patients. Cumulative medical costs resulting from all injury leading to hospital services is £374,354 (US$540,485). Average estimated cost per fall is £1120 (US$1617). Estimated cost of implementing the OEP for 535 people is £116,479 (US$168,504) or £217.72 (US$314.34) per-person. Based on effectiveness of the OEP it can be estimated that out of the 598 falls, 209 falls would be prevented. This suggests that £234,583 (US$338,116) savings could be made, a net benefit of £118,104 (US$170,623). CONCLUSIONS: Implementation of the OEP programme for patients with RA has potentially significant economic benefits and should be considered for patients with the condition

Using Artificial Intelligence-informed Experience-Based Co-Design (AI-EBCD) to create a virtual reality-based mindfulness application to reduce diabetes distress: protocol for a mixed-methods feasibility study

Introduction People with type 2 diabetes can experience diabetes distress which can negatively affect health outcomes. Non-pharmacological interventions such as mindfulness can help address diabetes distress. However, face-to-face programmes can be constrained by cost, poor accessibility and lack of availability. Mobile apps for mindfulness may overcome these issues but evidence of their effectiveness is limited, and some have poor interface design with basic visualisations and feedback. Methods and analysis Our study will explore using virtual reality (VR) as an immersive and interactive technology that could support mindfulness practice to help reduce diabetes distress. We will use a mixed-methods design to pilot a new co-design process called Artificial Intelligence-informed Experience-Based Co-Design. Phase 1 will identify and evaluate existing VR mindfulness apps, followed by interviews with mindfulness experts to gain their perspectives on practising mindfulness in virtual settings. This will be followed by a participatory design phase with a series of five co-design workshops where adults with type 2 diabetes will (1) discuss diabetes distress and learn about mindfulness, (2) evaluate commercially available VR mindfulness apps, (3) employ artistic methods to produce a personalised mindfulness experience, (4) create digital content for a virtual mindfulness experience via generative artificial intelligence tools and (5) prioritise key design features, functionality and content for a tailored VR mindfulness app. The final phase will focus on developing a bespoke VR mindfulness app and evaluating it with adults with type 2 diabetes using interviews, questionnaires and VR app analytics to determine if the new digital mental health intervention can help reduce diabetes distress and improve quality of life. Ethics and dissemination We received ethical approval from The University of Manchester (2024-18262-32710 and 2024-21170-37093). Written informed consent will be obtained from all participants. Dissemination will include scientific publications and presentations, social media, knowledge translation events and educational resources for teaching students

Analysis of large oxygenated and nitrated polycyclic aromatic hydrocarbons formed under simulated diesel engine exhaust conditions (by compound fingerprints with SPE/LC-API-MS)

The analysis of organic compounds in combustion exhaust particles and the chemical transformation of soot by nitrogen oxides are key aspects of assessment and mitigation of the climate and health effects of aerosol emissions from fossil fuel combustion and biomass burning. In this study we present experimental and analytical techniques for efficient investigation of oxygenated and nitrated derivatives of large polycyclic aromatic hydrocarbons (PAHs), which can be regarded as well-defined soot model substances. For coronene and hexabenzocoronene exposed to nitrogen dioxide under simulated diesel exhaust conditions, several reaction products with high molecular mass could be characterized by liquid chromatography-atmospheric pressure chemical (and photo) ionization-mass spectrometry (LC-APCI-MS and LC-APPI-MS). The main products of coronene contained odd numbers of nitrogen atoms (m/z 282, 256, 338), whereas one of the main products of hexabenzocoronene exhibited an even number of nitrogen atoms (m/z 391). Various reaction products containing carbonyl and nitro groups could be tentatively identified by combining chromatographic and mass spectrometric information, and changes of their relative abundance were observed to depend on the reaction conditions. This analytical strategy should highlight a relatively young technique for the characterization of various soot-contained, semi-volatile, and semi-polar reaction products of large PAHs

The effectiveness and cost-effectiveness of strength and balance Exergames to reduce falls risk for people aged 55 years and older in UK assisted living facilities: A multi-centre, cluster randomised controlled trial

Background: Falls are the leading cause of fatal and non-fatal unintentional injuries in older people. The use of Exergames (active, gamified video-based exercises) is a possible innovative, community-based approach. This study aimed to determine the effectiveness of a tailored OTAGO/FaME based strength and balance Exergame programme for improving balance, maintaining function and reducing falls risk in older people. Methods: A two-arm cluster randomised controlled trial recruiting adults aged 55 years and older living in 18 assisted-living (sheltered housing) facilities (clusters) in the UK. Standard care (physiotherapy advice and leaflet) was compared to a tailored 12-week strength and balance Exergame programme, supported by physiotherapists or trained assistants. Complete-case analysis (intention to treat) was used to compare Berg Balance Scale (BBS) at baseline and at 12 weeks. Secondary outcomes included: fear of falling, mobility, falls risk, pain, mood, fatigue, cognition, healthcare utilisation and health-related quality of life; self-reported physical activity and falls. Results: Eighteen clusters were randomised (9 to each arm) with 56 participants allocated to the intervention and 50 to the control (78% female, mean age 78 years). Fourteen participants withdrew over the 12 weeks (both arms), mainly for ill health. There was an adjusted mean improvement in balance (BBS) of 6.2 (95% CI 2.4 to 10.0), reduced fear of falling (p=0.007) and pain (p=0.02) in Exergame group. Mean attendance at sessions was 69% (mean exercising time of 33 minutes/week). 24% of control group and 20% of Exergame group fell over trial period. The change in falls rates significantly favoured the intervention (incident rate ratio 0.31 (95% CI 0.16 to 0.62, p=0.001)). The point estimate of the incremental cost effectiveness ratio (ICER) was £15,209.80 per QALY. Using 10,000 bootstrap replications, at the lower bound of the NICE threshold of £20,000 per QALY, there was a 61% probability of Exergames being cost-effective, rising to 73% at the upper bound of £30,000 per QALY. Conclusions: Exergames, as delivered in this trial, improve balance, pain and fear of falling and are a cost-effective fall prevention strategy in assisted living facilities for people aged 55 years or older

Falls prevention in community-dwelling older adults and implementation of world falls guidelines: a call for action across Europe by the European Geriatric Medicine Society Special Interest Group on Falls and Fractures

Falls among older adults represent a significant public health challenge due to their consequences, including serious injuries, increased morbidity and mortality, decreased quality of life, and heightened healthcare costs. The World Falls Guidelines (WFG), published in 2022, offer a robust framework for evidence-based interventions; however, the uptake of these guidelines into clinical practice across Europe remains inconsistent. Key barriers to implementation include insufficient resources, a lack of trained healthcare professionals, and limited integration into existing healthcare systems. This position paper by the EuGMS Special Interest Group (SIG) on Falls and Fractures addresses the implementation of the WFG among community-dwelling older adults and falls prevention across Europe by providing an overview of the current status of WFG adoption in Europe and discusses the challenges and opportunities for implementation. We provide an overview of the current resources to support the clinical practice of falls prevention, implementation guides, and educational programs. Additionally, we discuss what is necessary for the future development of these resources and for advancing research. The EuGMS SIG on Falls and Fractures advocates for a commitment of healthcare providers as well as insurers, policymakers, and other stakeholders to collaborative European initiatives—such as developing a standardised falls prevention strategy, promoting evidence-based implementation plans, establishing a European-wide research agenda, and creating under- and postgraduate curricula—which are essential for advancing falls prevention efforts across Europe

Striking Denervation of Neuromuscular Junctions without Lumbar Motoneuron Loss in Geriatric Mouse Muscle

Reasons for the progressive age-related loss of skeletal muscle mass and function, namely sarcopenia, are complex. Few studies describe sarcopenia in mice, although this species is the mammalian model of choice for genetic intervention and development of pharmaceutical interventions for muscle degeneration. One factor, important to sarcopenia-associated neuromuscular change, is myofibre denervation. Here we describe the morphology of the neuromuscular compartment in young (3 month) compared to geriatric (29 month) old female C57Bl/6J mice. There was no significant difference in the size or number of motoneuron cell bodies at the lumbar level (L1–L5) of the spinal cord at 3 and 29 months. However, in geriatric mice, there was a striking increase (by ∼2.5 fold) in the percentage of fully denervated neuromuscular junctions (NMJs) and associated deterioration of Schwann cells in fast extensor digitorum longus (EDL), but not in slow soleus muscles. There were also distinct changes in myofibre composition of lower limb muscles (tibialis anterior (TA) and soleus) with a shift at 29 months to a faster phenotype in fast TA muscle and to a slower phenotype in slow soleus muscle. Overall, we demonstrate complex changes at the NMJ and muscle levels in geriatric mice that occur despite the maintenance of motoneuron cell bodies in the spinal cord. The challenge is to identify which components of the neuromuscular system are primarily responsible for the marked changes within the NMJ and muscle, in order to selectively target future interventions to reduce sarcopenia
