Show moreBackgroundPain medication may have an impact on the quality of life (QoL) in persons with dementia, but may also influence care dependency and daily functioning. The aim of this study is to investigate the effect of regularly scheduled paracetamol on care dependency and daily functioning in persons with advanced dementia with low QoL living in long-term care facilities.MethodsThe Quality of life and Paracetamol In advanced Dementia (Q-PID) study was a (block) randomized double-blind placebo-controlled crossover trial with paracetamol and placebo across seventeen long-term care facilities across 9 care organizations in the western region of the Netherlands. Participants were >= 65 years, had advanced dementia (Global Deterioration Scale 5-7), and low QoL (QUALIDEM-6D score <= 70). Measurements were performed by nursing staff at the start and at the end of each treatment period of six weeks. Repeated linear mixed models were used to compute differences between randomization groups, with adjustment for period and order effects, and psychotropic use.ResultsNinety-five persons (mean age of 83.9 years, 57.4% female) were enrolled in the Q-PID study. The mean Care Dependency Scale total score was 37.8 (Standard Deviation [SD] 12.9) and the mean Katz-15 total score was 11.9 (SD 2.4). Repeated linear mixed models showed no difference in mean differences of care dependency (paracetamol - 1.0 [95% Confidence Interval (CI) -2.4-0.3], placebo + 0.1 [-1.3-1.5]), and daily functioning (paracetamol + 0.2 [95% CI -0.2-0.6], placebo + 0.1 [-0.3-0.4]).ConclusionsCompared to placebo, no effect of scheduled administration of paracetamol was found on care dependency and daily functioning in persons with advanced dementia with low QoL. Future research should focus on which specific items of care dependency need special attention to improve the care for persons with advanced dementia. A multi-domain approach is needed to enhance and/or maintain QoL of persons with advanced dementia.Trial registrationNetherlands Trial Register (NTR6766); http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=6766; Trial registration date: 20/10/2017.

Show moreObjectives This study aimed to determine best practices for involving family caregivers in interventions aimed at preventing and reducing responsive behaviour stemming from unmet needs, including pain.Design Scoping review, reported according to the Preferred Reporting Items for Systematic Reviews, Meta-Analyses extension for Scoping Reviews reporting guideline.Data sources PubMed, Embase, Emcare, Web of Science, COCHRANE Library, PsycINFO, Academic Search Premier and Cinahl searched up to 23 July 2023.Eligibility criteria Studies reporting on family involvement in interventions for nursing home residents with dementia were included.Data extraction and synthesis Two researchers independently extracted the data, followed by a content analysis.Results Of the 1486 records screened, 20 studies were included. Family caregivers were involved in interventions aimed at planning care, life review (eg, documentation of life experiences of their relative), and selecting activities for their relative. Family caregivers preferred an active role in developing optimal care for their relative. Drivers of success and barriers to family involvement centred around three themes: (1) communication between all involved; (2) prerequisites (organisational and other conditions) and (3) personal circumstances (family’s coping and skills).Conclusion Best practices for involving family caregivers in interventions aimed at addressing responsive behaviour in residents with dementia concerned those interventions in which family caregivers were given an important role in managing responsive behaviour. This means that, in order to achieve an active role of family caregivers in the whole care process, their needs must be taken into account. Show less

Show moreBackgroundAcademics aim to understand the experiences of people living with cognitive and/or language impairment in their search for epistemic justice. Methods that do not rely solely on verbal information (e.g., interviews, focus groups) but also employ an attunement to the non-verbal - such as participant observation and creative methods, are seen as a suitable way to do justice to people's non-verbal interactions. However, in practice, researchers still experience ethical issues in everyday encounters with participants with cognitive and/or language impairment even when trying to address epistemic issues while employing such methods. This article aims to demonstrate 1) the importance of attending to the non-verbal in order to prevent epistemic injustice in research and 2) how a case-study approach and discussing ethical dilemmas with peers may help to unpack some of the ethical tensions that the researchers experience.Aim and methodsThis article focuses on ethical dilemmas the authors encountered during their research projects in the past. Three cases chosen by the authors illustrate these dilemmas. Dilemmas are presented as auto-ethnographical written accounts, which were discussed during ten retrospective dialogical sessions (60–90 min) organized by the research group consisting of six academic researchers.ResultsEthically sound research, in which older people living with cognitive and/or language impairment are engaged, entails much more than following procedures about informed consent, privacy, submitting a proposal to an ethics committee, and using suitable methods and techniques. Ethical issues in these studies relate to everyday situations in which researchers tried to do justice to the knowledge of people who have difficulties expressing themselves verbally, but were challenged by what they have initially experienced as ‘having it wrong,’ ‘not knowing,’ and ‘losing something in translation’ in their practice. Finally, we learned that the interactions the researchers encountered were complex. They had to constantly evaluate the appropriateness of their approach, balance rational and intuitive forms of interaction and interpretation, and consider ways of communicating the research findings.Discussion and conclusionApproximating epistemic justice in research with people with cognitive and/or language impairment requires extra effort in daily research routines. Sharing everyday ethical issues via case stories and reflecting on these issues encourages moral learning and brings new knowledge about the craftsmanship of researchers. Especially the collaborative and dialogical reflection helped the researchers to dig deeper and find words for intangible processes that often remain unaddressed. However, sharing stories about ethical issues requires mutual trust and safety because sharing and reflecting may bring discomfort, messiness, and uncertainty. Show less

Show moreProspective cohort studies have implied associations between blood levels of troponin T, troponin I, NT-proBNP, GDF15, dementia, and cognitive function, without providing evidence favoring possible causality. We aimed to assess the causal associations of these cardiac blood biomarkers with dementia and cognition using two-sample Mendelian randomization (MR). Independent genetic instruments (p < 5e−7) for troponin T and I, N-terminal pro B-type natriuretic peptide (NT-proBNP) and growth-differentiation factor 15 (GDF15) were obtained from previously-performed genome-wide association studies of predominantly European ancestry. Summary statistics for gene-outcome associations in European-ancestry participants, for the two-sample MR analyses, were obtained for general cognitive performance (n = 257,842) and dementia (n = 111,326 clinically diagnosed and “proxy” AD cases, and 677,663 controls). Two-sample MR analyses were performed using inverse variance-weighted (IWV) analyses. Sensitivity analyses to evaluate horizontal pleiotropy included weighted median estimator, MR-Egger, and MR using cis-SNPs only. Using IVW, we did not find evidence for possible causal associations between genetically influenced cardiac biomarkers with cognition and dementia. For example, per standard deviation (SD) higher cardiac blood biomarker, the odds ratio for risk of dementia was 1.06 (95%CI 0.90; 1.21) for troponin T, 0.98 (95%CI 0.72; 1.23) for troponin I, 0.97 (95%CI 0.90; 1.06) for NT-proBNP and 1.07 (95%CI 0.93; 1.21) for GDF15. Sensitivity analyses showed higher GDF15 was significantly associated with higher dementia risk and worse cognitive function. We did not find strong evidence that cardiac biomarkers causally influence dementia risk. Future research should aim at elucidating the biological pathways through which cardiac blood biomarkers associate with dementia. Show less

Show moreObjective: We investigated motivations of patients and care partners for their memory clinic visit, and whether these are expressed in consultations.Methods: We included data from 115 patients (age 71 +/- 11, 49% Female) and their care partners (N = 93), who completed questionnaires after their first consultation with a clinician. Audio-recordings of these consultations were available from 105 patients. Motivations for visiting the clinic were content-coded as reported by patients in the questionnaire, and expressed by patients and care partners in consultations.Results: Most patients reported seeking a cause for symptoms (61%) or to confirm/exclude a (dementia) diagnosis (16%), yet 19% reported another motivation: (more) information, care access, or treatment/advice. In the first consultation, about half of patients (52%) and care partners (62%) did not express their motivation(s). When both expressed a motivation, these differed in about half of dyads. A quarter of patients (23%) expressed a different/complementary motivation in the consultation, then reported in the questionnaire.Conclusion: Motivations for visiting a memory clinic can be specific and multifaceted, yet are often not addressed during consultations. Practice implications: We should encourage clinicians, patients, and care partners to talk about motivations for visiting the memory clinic, as a starting point to personalize (diagnostic) care.

Show moreMuch is known about palliative care needs of persons with dementia and their family. Less is known about how to successfully implement models that address those needs. We present specialist models in the Netherlands (2017-2018) and Northern Ireland (2016-2017) contrasting its evaluations. From implementation failure in the Netherlands compared with successful implementation in Northern Ireland, we learn that recognizing roles and competencies among all involved is essential in developing effective partnership relationships. All of this is facilitated by referral before the end of life and offering various training programs and in-patient and out-patient services and therapies to show benefits early. Show less

Show moreBackgroundTo support family caregivers of people with dementia in end-of-life decision making, a family booklet on comfort care has been adapted and adopted by several European jurisdictions since the original publication in Canada in 2005.MethodsWe analyzed and compared the adaptations to the family booklets used in Canada, the Czech Republic, Italy, the Netherlands, the UK and Ireland that were made up to 2021. Qualitative content analysis was used to create a typology of changes to the original booklet. Interviews with the teams that adapted the booklets contributed to methodological triangulation. Further, using an established framework, we assessed whether the contents of the booklets addressed all domains relevant to optimal palliative dementia care.ResultsThe booklets differed in the types of treatment addressed, in particular tube feeding, euthanasia, and spiritual care. There was also variability in the extent to which medical details were provided, an emphasis on previously expressed wishes in medical decision making, addressing of treatment dilemmas at the end of life, the tone of the messages (indirect or explicit) and the discussion of prognosis (as more or less positive), and the involvement of various healthcare professionals and family caregivers in care. All booklets addressed all domains of palliative dementia care.ConclusionsWe identified core elements in providing information on end-of-life care to family caregivers of people with dementia as related to optimal palliative care in dementia. Additionally, local adaptations and updates are required to account for socio-cultural, clinical, and legal differences which may also change over time. These results may inform development of educational and advance care planning materials for different contexts. Show less

Show moreThe ageing revolution is changing the composition of our society with more people becoming very old with higher risks for developing both pain and dementia. Pain is normally signaled by verbal communication, which becomes more and more deteriorated in people with dementia. Thus, these individuals unnecessarily suffer from manageable but unrecognized pain. Pain assessment in patients with dementia is a challenging endeavor, with scientific advancements quickly developing. Pain assessment tools and protocols (mainly observational scales) have been incorporated into national and international guidelines of pain assessment in aged individuals. To effectively assess pain, interdisciplinary collaboration (nurses, physicians, psychologists, computer scientists, and engineers) is essential. Pain management in this vulnerable population is also preferably done in an interdisciplinary setting. Nonpharmacological management programs have been predominantly tested in younger populations without dementia. However, many of them are relatively safe, have proven their efficacy, and therefore deserve a first place in pain management programs. Paracetamol is a relatively safe and effective first-choice analgesic. There are many safety issues regarding nonsteroidal anti-inflammatory drugs, opioids, and adjuvant analgesics in dementia patients. It is therefore recommended to monitor both pain and potential side effects regularly. More research is necessary to provide better guidance for pain management in dementia. Show less

Show moreIntroduction: Cognitive impairment and frailty are important health determinants, independently associated with increased dementia risk. In this meta-analysis we aimed to quantify the association of the co-occurrence of cognitive impairment no dementia (CIND) and physical frailty with incident dementia.Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used when reporting this review. We performed a systematic search on PubMed, Web of Science, and Embase databases for relevant articles. Longitudinal studies enrolling individuals with both CIND and physical frailty and reporting dementia incidence were eligible. Pooled estimates were obtained through random effect models and Mantel-Haenszel weighting.Results: Out of 3684 articles, five (14302 participants) were included in the meta-analysis. In comparison to participants free from frailty and CIND, the pooled hazard ratio for dementia was 3.83 (95% confidence interval (CI]: 2.64-5.56) for isolated CIND, 1.47 (95%CI: 0.89-2.40) for isolated physical frailty, and 5.36 (95%CI: 3.26-8.81) for their co-occurrence.Discussion: The co-occurrence of cognitive impairment and physical frailty is a clinical marker of incident dementia.

Show moreObjectives: Previous studies have shown large heterogeneity in the progression of dementia, both within and between patients. This heterogeneity offers an opportunity to limit the global and individual burden of dementia through the identification of factors associated with slow disease progression in dementia. We explored the heterogeneity in dementia progression to detect disease, patient, and social context factors related to slow progression.Design: Two longitudinal population-based cohort studies with follow-up across 12 years.Setting and Participants: 512 people with incident dementia from Stockholm (Sweden) contributed to the Kungsholmen Project and the Swedish National Study of Aging and Care in Kungsholmen.Methods: We measured cognition using the Mini-Mental State Examination and daily functioning using the Katz Activities of Daily Living Scale. Latent classes of trajectories were identified using a bivariate growth mixture model. We then used bias-corrected logistic regression to identify predictors of slower progression.Results: Two distinct groups of progression were identified; 76% (n = 394) of the people with dementia exhibited relatively slow progression on both cognition and daily functioning, whereas 24% (n = 118) demonstrated more rapid worsening on both outcomes. Predictors of slower disease progression were Alzheimer's disease (AD) dementia type [odds ratio (OR) 2.07, 95% confidence interval (CI) 1.15-3.71], lower age (OR 0.88, 95% CI 0.83-0.94), fewer comorbidities (OR 0.77, 95% CI 0.66-0.90), and a stronger social network (OR 1.72, 95% CI 1.01-2.93).Conclusions/Implications: Lower age, AD dementia type, fewer comorbidities, and a good social network appear to be associated with slow cognitive and functional decline. These factors may help to improve the counseling of patients and caregivers and to optimize the planning of care in dementia. (C) 2019 AMDA - The Society for Post-Acute and Long-Term Care Medicine.
