Background: This study was initiated and co-designed by a Participant and Public Involvement (PPI) group attached to HOMESIDE, a randomized controlled trial that investigated music and reading interventions for people living with dementia and their family caregivers across five countries: Australia, Germany, Norway, Poland, and the UK. The aim was to capture experiences of PPI across the five countries, explore the benefits and challenges of PPI in dementia research, and identify contributions made to the study., Methods: We surveyed PPI members and academic researchers who collaborated on the HOMESIDE study. The survey was co-designed through consultation with PPI members and academics, alongside a small scoping literature review. Survey questions covered four topics: (1) expectations for PPI, (2) perceived contributions of PPI to the research study, (3) benefits and challenges of PPI, and (4) recommendations for future PPI in dementia research., Results: There were 23 responses, representing 50% of the PPI members (n = 16) and 29% of academics (n = 7). PPI was found to be beneficial to the research and individuals involved. Contributions to the research included supporting recruitment and publicity, advising on the design of participant-facing materials, guiding the design and delivery of the interventions, and identifying cultural differences affecting research delivery. PPI members benefited from building connections, sharing experiences and receiving support, learning about dementia and research, and gaining new unexpected experiences. Academics learned about the realities of living with dementia, which they felt informed and grounded their work. Several challenges were identified, including the need for clear expectations and objectives, inconsistency of PPI members across research stages, limitations of meeting online versus in-person, scheduling difficulties, and language barriers., Conclusions: This study identifies important considerations for implementing PPI within dementia studies and international healthcare research more broadly. Our findings guided the development of five recommendations: (1) involve PPI members as early as possible and throughout the research process; (2) create a space for constructive criticism and feedback; (3) have clear tasks, roles, and expectations for PPI members; (4) involve PPI members with a diverse range of experiences and backgrounds; and (5) embed infrastructure and planning to support PPI., (© 2024.

The behavioral and psychological symptoms of dementia (BPSD) can be challenging for family caregivers to cope with, leading to distress and fatigue. It is therefore important to offer effective strategies to reduce the impact of BPSD. The HOMESIDE randomized controlled trial (RCT) was testing purposefully developed interventions to improve the quality of life and wellbeing of dyads of people with dementia and family caregivers as a result of reduction of BPSD. HOMESIDE RCT was conducted in Australia, Germany, Norway, Poland and the United Kingdom between 2019 and 2022. The study design was a three-arm parallel-group single-blinded, pragmatic RCT with a sample size of 432 dyads. Dyads were randomly allocated to one of three treatment conditions: Music Intervention plus Standard Care; or Reading Intervention plus Standard Care; or Standard Care only. The Reading Intervention (RI) within the HOMESIDE RCT aimed to evoke shared discussion, reminiscence, meaningful shared experiences and consequently enrich everyday life, interaction and the emotional connection between the caregiver (CG) and carereceiver (CR); as well as to enhance activities of daily living and to promote relaxation or stimulation as appropriate. This paper describes the underlying conceptual framework, the content, and delivery of the Reading Intervention within the HOMESIDE RCT., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Background: Music interventions provided by qualified therapists within residential aged care are effective at attenuating behavioural and psychological symptoms (BPSD) of people with dementia (PwD). The impact of music interventions on dementia symptom management when provided by family caregivers is unclear., Methods: We implemented a community-based, large, pragmatic, international, superiority, single-masked randomised controlled trial to evaluate if caregiver-delivered music was superior to usual care alone (UC) on reducing BPSD of PwD measured by the Neuropsychiatric Inventory-Questionnaire (NPI-Q). The study included an active control (reading). People with dementia (NPI-Q score ≥6) and their caregiver (dyads) from one of five countries were randomly allocated to caregiver-delivered music, reading, or UC with a 1:1:1 allocation stratified by site. Caregivers received three online protocolised music or reading training sessions delivered by therapists and were recommended to provide five 30-min reading or music activities per week (minimum twice weekly) over 90-days. The NPI-Q severity assessment of PwD was completed online by masked assessors at baseline, 90- (primary) and 180-days post-randomisation and analysed on an intention-to-treat basis using a likelihood-based longitudinal data analysis model. ACTRN12618001799246; ClinicalTrials.govNCT03907748., Findings: Between 27th November 2019 and 7th July 2022, we randomised 432 eligible of 805 screened dyads (music n = 143, reading n = 144, UC n = 145). There was no statistical or clinically important difference in the change from baseline BPSD between caregiver-delivered music (-0.15, 95% CI -1.41 to 1.10, p = 0.81) or reading (-1.12, 95% CI -2.38 to 0.14, p = 0.082) and UC alone at 90-days. No related adverse events occurred., Interpretation: Our findings suggested that music interventions and reading interventions delivered by trained caregivers in community contexts do not decrease enduring BPSD symptoms., Funding: Our funding was provided by National Health and Medical Research Council, Australia; The Research Council of Norway; Federal Ministry of Education and Research, Germany; National Centre for Research and Development, Poland; Alzheimer's Society, UK, as part of the Joint Programme for Neurodegenerative Diseases consortia scheme., Competing Interests: All authors declared no conflicts of interest., (© 2023 The Author(s).)

Background: There is a global need for interventions that support the wellbeing of people living with dementia and their family care partners. Studies show that shared musical activities may achieve this. Our systematic review aimed to synthesise existing research exploring dyads' experiences of shared musical activities across a range of contexts., Method: From 31 October 2020 we searched PubMed, PsycInfo, CINAHL Complete, EMBASE, RILM, Web of Science Core Collection, Google Scholar and ProQuest Dissertations & Theses for studies published up to 14 April 2021, and hand searched five music therapy journals plus citation lists. Thirteen qualitative studies reporting on dyads' experiences and perspectives of shared musical activities across a range of settings were included. Studies with mixed populations or mixed modality interventions were excluded. We analysed the final studies using thematic synthesis, engaging in reflective discussions and reflexivity throughout. The quality of included studies was assessed using the CASP qualitative checklist. This study is registered on PROSPERO: CRD42020169360., Results: Six themes were identified from 13 studies: 1) shared musical activities support wellbeing for people living with dementia, 2) music groups become ecological systems, 3) shared musical activities are experienced differently over time, 4) shared musical activities are experienced by me and as we , 5) music is a supportive structure, and 6) the thread of connection (an overarching theme). A GRADE-CERQual assessment found moderate to high confidence in these findings. Findings informed the development of the Contextual Connection Model of Health Musicking., Conclusion: Shared musical activities foster experiences of connection for people living with dementia and their family care partners. Experiences of connection are supported through professional facilitation and the structural aspects of music, and are influenced by the setting and changes over time. These experiences of connection play a central role in supporting dyadic and individual wellbeing. These findings are largely relevant to a western cultural context; future research should seek to include more diverse cultural experiences.

An increasing number of people with dementia receive informal care from family members to help them remain living in the community. Music therapy is particularly beneficial for supporting the wellbeing of people living with dementia. However, little is known about how music therapy might support people with dementia and their family care partners as dyads. This study explored the experiences of six dyads participating in a 12-week home-based skill-sharing music intervention facilitated by a music therapist. We examined their experiences during the intervention period and in the 3-6 months following. This study was conducted within a larger randomised control trial, HOMESIDE. Data was collected through video-recorded music-based interviews, participant diaries, and a semi-structured interview. Data was analysed using an abductive and relational-centred research approach in consideration of the Contextual Connection Model of Health Musicking for People Living with Dementia and Their Family Care Partners . The study found fifteen themes that describe dyads' supported experiences of sharing music in their homes. These were organised into three global themes: (1) experiences were shaped by complex influences; (2) a connected musical ecosystem; and (3) music was a resource for wellbeing. This study highlighted the important role of personalised facilitation and the therapeutic relationship as dyads learned to use music as a resource through a process of trial and error. The implications for skill-sharing, indirect music therapy and direct music therapy practice are discussed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 McMahon, McFerran, Clark, Odell-Miller, Stensæth, Tamplin and Baker.)

Background: Most people with dementia live in the community, not in residential care. Therefore, quality informal care for them is critical for managing behavioural and psychological symptoms of dementia (BPSD). Music therapy has been shown to reduce BPSD. However, no randomised controlled trial has examined the effects of music interventions delivered by caregivers in home settings. The HOME-based caregiver-delivered music intervention for people living with dementia (HOMESIDE) trial aims to evaluate the effectiveness of a 12-week music intervention in addition to standard care for BPSD. This article describes the statistical analysis plan., Methods and Analysis: HOMESIDE is a large, pragmatic international three-arm parallel-group randomised controlled trial. Dyads (persons with dementia and caregiver) in Australia, Germany, the UK, Poland and Norway were randomised to receive music and standard care, reading and standard care or standard care alone. The primary outcome is BPSD (proxy) of the person living with dementia, measured using the Neuropsychiatric Inventory-Questionnaire (NPI-Q) at 90 and 180 days post-randomisation. Longitudinal analysis will compare NPI-Q severity between music and standard care versus standard care alone. Secondary outcomes include quality of life and depression (both person with dementia and caregiver), cognition (person with dementia only), distress, resilience, competence and caregiver-patient relationship (caregiver only). Treatment effects will be obtained at 90 and 180 days post-randomisation, where applicable. Safety outcomes (adverse events, hospitalisations, deaths) will be summarised., Discussion: This statistical analysis plan provides a detailed methodology for the analysis of HOMESIDE and will improve the validity of the study and reduce the potential for bias., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12618001799246.

Background: While studies have identified strategies that are useful for recruiting people living with dementia, none have focused on psychosocial interventions involving arts therapies, or have examined the profiles of older people living in the community who consent or decline participation, particularly during a global pandemic. We aimed to identify the most effective recruitment strategies according to participant characteristics and transnational differences and develop a profile of consenting and non-consenting participants., Methods: Recruitment teams in Australia, Norway, Germany, Poland, and the United Kingdom, recorded participants' source of study awareness and characteristics of consenting and non-consenting participants. Distributions of participants 'consenting to participate' were compared and logistic regressions were used to estimate the odds ratios., Results: Consenting female caregivers were disproportionally represented. Study awareness differed between countries but overall, most expressions of interest to participate were derived from referrals from professionals or organisations, or from databases of people wanting to participate in research. Troughs in recruitment rates occurred during Northern Hemisphere summer vacation periods, and during Christmas periods., Conclusions: This study found that recruiting for a trial with community-dwelling family caregivers and people living with dementia is challenging, especially during a global pandemic. While spousal caregivers comprised the highest proportion of dyads recruited, overall spousal caregivers were more reluctant to consent to participate than adult child caregivers. More targeted recruitment strategies designed for minority groups are also needed to ensure broader representation in dementia treatment studies., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Background: The number of people living with dementia (PwD) worldwide is expected to double every 20 years. Many continue living at home, receiving support from family caregivers who may experience significant stress, simultaneously to that of the PwD. Meaningful and effective home-based interventions to support PwD and their caregivers are needed. The development of a theory- and practice-driven online home-based music intervention (MI) is delivered by credentialed music therapists, nested within the HOMESIDE RCT trial. Methods: Dyads including the PwD and their family carer are randomised to MI, reading (RI) or standard care (SC). MI aims to support health wellbeing and quality of life by training caregivers to intentionally use music (singing, instrument playing, movement/dancing, and music listening) with their family member (PwD) in daily routines. MI is underpinned by cognitive, relational, social, and psychological theories of mechanisms of change. Results: Preliminary sub-cohort results analyses show MI can be delivered and is accepted well by participants and music-therapist interventionists across five countries. Conclusions: The specialist skills of a music therapist through MI enable carers to access music when music therapists are not present, to meet carer and PwD needs. Music therapists embrace this changing professional role, observing therapeutic change for members of the dyads.

Positive effects of music therapy for people with dementia and their family carers are reported in a growing number of studies. However, small sample sizes or low recruitment rates often limit the success of these research studies. More adequately powered evidence-based studies are needed to impact policy and funding in dementia care. This systematic review examined recruitment strategies in music therapy clinical trials involving people living with dementia and/or their family carers. Eligible studies described enrolment, consent, accrual, or recruitment methods as well as recruitment or consent rates. Thirty studies with a total of 1,192 participants were included. Recruitment and conversion rates in residential aged care facilities (RACFs) (14 studies) were substantially higher than in community-based studies (16 studies). Whereas studies in RACFs most commonly recruited participants through staff approaching residents face-to-face or conversing with residents' legal guardians, community-based studies utilized a vast array of strategies, including staff referral, demonstrations/information sessions by researchers, advertisements, and direct contact with residents. Recruitment rates are likely to be higher when recruiters have an existing relationship with potential participants and when an independent third-party dementia organization is involved. Randomized controlled trials led to equally or greater recruitment conversion rates than other designs. Findings suggest that recruitment in dementia trials is complex, challenging, and needs thorough planning and consideration to be time- and cost-effective. Future studies should include reporting of recruitment strategies, enrolment rates, and related aspects so that researchers can better design recruitment strategies and estimate resources needed to reach the target sample size., (© Crown copyright 2021.)

The point of departure in this text is the ongoing qualitative interdisciplinary research project RHYME (www.RHYME.no), which addresses the lack of health-promoting interactive and musical Information and Communications Technology (ICT) for families with children with severe disabilities. The project explores a new treatment paradigm based on collaborative, tangible, interactive net-based musical "smart things" with multimedia capabilities. The goal in RHYME is twofold: (1) to reduce isolation and passivity, and (2) to promote health and well-being. Co-creation is suggested as a possible path to achieving these goals, by evoking feelings, for example, or accommodating the needs to act and to create social relations; co-creation also motivates users to communicate and collaborate within (new) social relations. This article engages co-creation by incorporating aspects connected to interaction design and the field of music and health. Empirical observations will be referred to. The research question is as follows: What might co-creation imply for families of children with disabilities when musical and interactive tangibles are used as health-promoting implements?

Background: Percutaneous angioplasty is an alternative to thrombolysis to reestablish coronary blood flow in patients with transmural myocardial infarction. At present, this treatment option is not widely accepted in Norway., Material and Methods: From 1996 to 1998, one hundred consecutive patients were treated with angioplasty for acute transmural infarction. The angiography showed one-vessel disease in 55%, two-vessel in 25%, and multivessel in 20%. The infarct related artery was the LAD in 44%, the CX in 14%, the RCA in 41%, and bypass graft in one. 92% had TIMI 0 or 1 flow. Stent was placed in 73%, GPIIb/IIIa was used in 11% and temporary pacemaker placed in 5%., Results: Successful angioplasty was performed in 95%, 3% was not done, and 2% failed. Peripheral stenoses were treated in 15% and stenoses in other arteries in 10%. Complications and events within 24 hours related to the angioplasty were seen in 9%., Conclusion: Primary angioplasty for acute myocardial infarction can be done with high primary success, good short-term results and few complications.

During the period 1994-95, 22 patients were examined with CT during arterial portography for evaluation of hepatic tumours. The majority, 20 patients, had metastases from colon cancer. All patients were candidates for liver resection. In the series of patients described here, this process detected additional lesions in four more of the patients than found with any other imaging techniques. This supports that CT during arterial portography is the most sensitive method for detecting small malignant hepatic tumours, and for localizing them in relation to liver segments and major vascular structures. Optimal results are obtained in the absence of diffuse parenchymal disease and portal hypertension. Non-tumourous perfusion defects limit the accuracy of this technique, but such defects have characteristic locations and appearance. In difficult cases the technique should be correlated with ultrasonography and MR.

A 72 year old man with coronary heart disease underwent cardioangiographic examination using monomeric non-ionic contrast medium. During and after the examination he gradually developed nearly total cortical blindness. His vision slowly returned after two days, but was not fully restored. Computer tomography (CT) of the brain five hours after the examination showed bilateral contrast medium retention in the visual cortex area, which became normal the day after. The gradual development of nearly total blindness combined with bilateral transient CT-alterations in the visual cortex area suggest a complication induced by the contrast medium.
