Complementary pre-screening strategies to uncover hidden prodromal and mild Alzheimer's disease: Results from the MOPEAD project.

INTRODUCTION: The Models of Patient Engagement for Alzheimer's Disease (MOPEAD) project was conceived to explore innovative complementary strategies to uncover hidden prodromal and mild Alzheimer's disease (AD) dementia cases and to raise awareness both in the general public and among health professionals about the importance of early diagnosis. METHODS: Four different strategies or RUNs were used: (a) a web-based (WB) prescreening tool, (2) an open house initiative (OHI), (3) a primary care-based protocol for early detection of cognitive decline (PC), and (4) a tertiary care-based pre-screening at diabetologist clinics (DC). RESULTS: A total of 1129 patients at high risk of having prodromal AD or dementia were identified of 2847 pre-screened individuals (39.7%). The corresponding proportion for the different initiatives were 36.8% (WB), 35.6% (OHI), 44.4% (PC), and 58.3% (DC). CONCLUSION: These four complementary pre-screening strategies were useful for identifying individuals at high risk of having prodromal or mild AD.

Nature-based interventions to promote health for people with stress-related illness: An integrative review.

BACKGROUND: Stress-related illness is increasing and is a common cause of sick leave. Spending time in nature have a positive effect on health and well-being for instance by reducing stress. Specific programmes with nature-based interventions (NBI) with the intention to involve people in activities in a supportive natural environment have been developed for people with stress-related illness. AIM: To identify and summarise scientific studies of NBIs to promote health for people with stress-related illness. METHOD: The design used in this study is integrative literature review. Scientific studies focusing on any type of NBI for people with stress-related illness were sought in Cinahl, PubMed, PsycInfo, AMED and Scopus. In total, 25 studies using both qualitative and quantitative designs were included in the review. RESULT: The reviewed studies focused on garden or forest interventions. In the majority of the studies, NBIs were performed in groups, including individual activities, and the length of programmes varied. Interventions in natural environments have unique qualities for individualised, meaningful activities and interactions with others in a non-demanding atmosphere. NBIs offer restoration that reduces stress, improves health and well-being and strengthen self-efficacy and work ability. Connectedness with nature support existential reflections and people with stress-related illness can achieve balance in everyday life. CONCLUSION: In conclusion, NBIs may have advantages to promote health for people with stress-related illness and should therefore be considered as an alternative to those affected. Further research from different perspectives, including nursing, is needed to understand the possibilities of NBIs and how they can be integrated into practice.

The MOPEAD project: Advancing patient engagement for the detection of "hidden" undiagnosed cases of Alzheimer's disease in the community.

In most, if not all health systems, dementia is underdiagnosed, and when diagnosis occurs, it is typically at a relatively late stage in the disease process despite mounting evidence showing that a timely diagnosis would result in numerous benefits for patients, families, and society. Moving toward earlier diagnoses in Alzheimer's disease (AD) requires a conscientious and collective effort to implement a global strategy addressing the multiple causes hindering patient engagement at different levels of society. This article describes the design of the Models of Patient Engagement for Alzheimer's Disease project, an ongoing EU-funded public-private multinational initiative that will compare four innovative patient engagement strategies across five European countries regarding their ability to identify individuals with prodromal AD and mild AD dementia, which are "hidden" in their communities and traditionally not found in the typical memory clinic setting. The strategies include an online AD citizen science platform, an open house initiative at the memory clinics, and patient engagement at primary care and diabetologist clinics.

Stakeholders' perceptions of value of nature-based interventions in promoting health in people with stress-related illness: a qualitative study.

Stress-related illness is a common and increasing cause for sick leave in Sweden. Spending time in nature reduces stress and promotes health and well-being. Accordingly, nature-based interventions (NBI) for people with stress-related illness have been developed and implemented in southern Scandinavia; however, such interventions are uncommon in the Circumpolar North. Previous studies have examined the effects and experiences of participating in NBI, but research about different stakeholders' perspectives on NBI is lacking. The aim of this study was to explore different key stakeholders' perceptions of the value of NBI in promoting health in people with stress-related illness. Data were collected through semi-structured interviews with 11 persons with stress-related illness experience, 14 healthcare professionals, and 11 entrepreneurs offering NBI. Qualitative content analysis resulted in four categories: Providing opportunity for recovery, Offering new perspectives and opportunity for reflection, Empowering balance and control in life, and Enabling one to overcome barriers. Although the study was conducted in a region where NBI is not widely implemented, the different stakeholders expressed similar perceptions of the value of NBI, indicating that NBI may be a valuable complement to health care which reaches people with stress-related illness needs and promotes their health.

Role stress among first-line nurse managers and registered nurses - a comparative study.

BACKGROUND: Studies show that first-line nurse managers (F-LNMs) experience high psychological job demands and inadequate managerial guidance. The purpose of this study was to investigate whether F-LNMs have higher stress levels and show more signs of stress-related ill health than registered nurses (RNs). AIM: The aim of this study was to examine possible differences in self-rated health between F-LNMs and RNs on various psychosocial factors (e.g. job demand, job control and managerial support). METHODS: Data were collected at a university hospital in Sweden. Sixty-four F-LNMs and 908 RNs filled in a web-based questionnaire. RESULTS: Both F-LNMs and RNs reported having good health. Approximately 10-15% of the F-LNMs and RNs showed signs of being at risk for stress-related ill health. Statistically significant differences (Mann-Whitney U-test) were found in the distribution between the F-LNMs and the RNs on three indices of job control, job demand and managerial support. CONCLUSION: Our findings suggest that F-LNMs were able to cope with high-demand job situations because of relatively high control over work. IMPLICATION FOR NURSING MANAGEMENT: The implication for nursing management shows the needs for a work environment for both F-LNMs and RNs that includes high job control and good managerial support.

Experiences of a nature-based intervention program in a northern natural setting: A longitudinal case study of two women with stress-related illness.

PURPOSE: This study explored the experiences of people with stress-related illness participating in a nature-based intervention programme in a northern natural setting. METHODS: A longitudinal case study was conducted with two women participating in a nature-based intervention programme on a farm. Data were collected by semi-structured interviews, diaries, rating scales, and self-assessment. Qualitative data were analysed by qualitative content analysis and quantitative data are presented descriptively. RESULTS: The theme of finding a source for recovery and well-being permeates all categories. The participants perceived the farm and nature to be a calming refuge; they learned to be in the present and could manage the tasks. In togetherness with each other and the facilitator on the farm they felt understood and confident, experienced joy, and found opportunities for change. They gained knowledge and positive memories and found new approaches in life. Self-assessment questionnaires indicated improvements of functioning in everyday life and reduced stress-related exhaustion at the end of the NBI programme. CONCLUSIONS: Nature-based interventions lasting for a relatively short period seem to promote health and may be a complement to other treatments of stress-related illness. Further research is needed with a larger number of participants and in various natural settings.

The affordability of lecanemab, an amyloid-targeting therapy for Alzheimer's disease: an EADC-EC viewpoint.

Lecanemab, an anti-amyloid antibody with effects on biomarker and clinical endpoints in early Alzheimer's Disease (AD), was granted accelerated approval by the FDA in 2023 and regulatory review in Europe is ongoing. We estimate the population potentially eligible for treatment with lecanemab in the 27 EU countries to 5.4 million individuals. Treatment costs would exceed 133 billion EUR per year if the drug is priced similarly as in the United States, amounting to over half of the total pharmaceutical expenditures in the EU. This pricing would be unsustainable; the ability to pay for high-priced therapies varies substantially across countries. Pricing similarly to what has been announced for the United States may place the drug out of reach for patients in some European countries. Disparities in access to novel amyloid-targeting agents may further deepen the inequalities across Europe in health outcomes. As representatives of the European Alzheimer's Disease Consortium Executive Committee, we call for pricing policies that allow eligible patients across Europe to access important innovations, but also continued investments in research and development. Infrastructure to follow up the usage of new therapies in routine care and new payment models may be needed to address affordability and inequalities in patient access.

A Cost-Consequence Analysis of Different Screening Procedures in Alzheimer's Disease: Results from the MOPEAD Project.

BACKGROUND: For care planning and support, under-detection and late diagnosis of Alzheimer's disease (AD) is a great challenge. Models of Patient-Engagement for Alzheimer's Disease (MOPEAD) is an EU-funded project aiming at testing different strategies to improve this situation. OBJECTIVE: To make a cost-consequence analysis of MOPEAD. METHODS: Four screening strategies were tested in five countries (Germany, the Netherlands, Slovenia, Spain, and Sweden): 1) a web-approach; 2) Open-House initiative; 3) in primary care; and 4) by diabetes specialists. Persons-at-risk of AD in all strategies were offered referral to a hospital-based specialist. The primary health-economic outcome was the cost per true-positive case (TP) of AD from the screened population. RESULTS: Of 2,847 screened persons, 1,121 screened positive (39%), 402 were evaluated at memory clinics (14%), and 236 got an AD diagnosis (8%). The cost per TP of those screened was €3,115 with the web-approach, €2,722 with the Open-House, €1,530 in primary care, and €1,190 by diabetes specialists. Sensitivity analyses that more likely reflect the real-world situation confirmed the results. The number-needed-to-screen was 30 with the web-approach, 8 with the Open-House and primary care, and 6 with the diabetes specialists.There were country differences in terms of screening rates, referrals to memory clinics, staff-types involved, and costs per TP. CONCLUSION: In primary care and by the diabetes specialist, the costs per TP/screened population were lowest, but the capacity of such settings to identify cases with AD-risk must be discussed. Hence new diagnostic strategies such as web-solutions and Open-House initiatives may be valuable after modifications.

General practitioners' attitude toward early and pre-dementia diagnosis of AD in five European countries-A MOPEAD project survey.

INTRODUCTION: General practitioners (GPs) play a key role in early identification of dementia, yet diagnosis is often missed or delayed in primary care. As part of the multinational Models of Patient Engagement for Alzheimer's Disease project, we assess GPs' attitude toward early and pre-dementia diagnosis of AD and explore barriers to early diagnosis. METHODS: Our survey covered general attitude toward early diagnosis, diagnostic procedures, resources, and opinion on present and future treatment options across five European countries. RESULTS: In total 343 GPs completed the survey; 74% of GPs indicated that an early diagnosis is valuable. There were country-specific differences in GPs' perceptions of reimbursement and time available for the patient. If a drug were available to slow down the progression of AD, 59% of the GPs would change their implementation of early diagnosis. DISCUSSION: Our findings provide insight into GPs' attitudes by exploring differences in perception and management of early diagnosis.

Between being and doing - the nature of leadership of first-line nurse managers and registered nurses.

AIMS AND OBJECTIVES: The aim of this study was to describe first-line nurse managers' (F-LNMs) and subordinate registered nurses' (RNs) conceptions and experiences of their routine work and how leadership was exercised. BACKGROUND: Extensive changes in health care organisations have had a powerful impact on leadership in nursing management. Nursing leadership, in turn, has an affect on both the quality of care and the subordinates' work environment. Therefore, it is important to enhance our understanding of current leadership in nursing management. DESIGN: This is a descriptive qualitative study carried out in three units at three Swedish hospitals. METHODS: Three F-LNMs and 14 RNs participated. Interviews were used to collect data. The interviews were analysed using qualitative content analysis. RESULTS: The result of this study was illustrated in one main theme referred to in this study as between being and doing. The RNs and F-LNMs described what it was to be a good professional (being), how they were engaged in creating a good work climate (doing) and personal outcomes of this project (gaining). CONCLUSION: The reciprocal relation between being and doing, which can be described as the development of virtues, was a central point in the professional work of the F-LNMs and RNs. The development of virtues is also a strategy to attain the goals of nursing and establish a work climate that motivates staff and improves performance. RELEVANCE TO CLINICAL PRACTICES: The implication for nursing management is to create ample space to develop strategies and knowledge about how leadership in nursing management can stimulate the development of a common perspective of good care and professional virtues appropriate for health care praxis.

Quantifying and Describing the Natural History and Costs of Alzheimer's Disease and Effects of Hypothetical Interventions.

BACKGROUND: A long-term horizon is necessary when the socioeconomic consequences and the potential effects of interventions in Alzheimer's disease (AD) are estimated. OBJECTIVES: To illustrate the potential societal costs of AD across the disease continuum and to illustrate the potential cost-effectiveness of a hypothetical intervention with disease modifying treatment (DMT). METHODS: Based on the Swedish dementia registry, a Markov model was used to simulate a virtual cohort of 100,000 people with mild cognitive impairment (MCI) due to AD (AD-MCI) in Sweden for 40 years starting at the age of 60. A simulated hypothetical intervention assumed a 25% reduction in progression rate during AD-MCI and mild AD-dementia. A comprehensive set of sensitivity analyses was included. RESULTS: The cumulative risk to develop dementia was 96%. The mean simulated survival was 19.0 years. The net present value for a person year with dementia was 252,843 SEK (about 29,500 US$). The cost effectiveness model illustrated how the hypothetical scenario of a 25% reduction in progression to AD-dementia would require 41 AD-MCI patients to be treated to prevent one case of AD-dementia (2,447 avoided AD-dementia cases of 100,000 with AD-MCI). Most scenarios illustrated hypothetical cost effectiveness (based on a willingness to pay level of 600,000 SEK (70,000 US$) per gained QALY), but not cost savings. DISCUSSION: Lifetime societal costs of AD are substantial. A future DMT may be potentially cost-effective given assumed treatment effects and costs, but cost savings are unlikely.

Cerebrospinal fluid and blood biomarkers for neurodegenerative dementias: An update of the Consensus of the Task Force on Biological Markers in Psychiatry of the World Federation of Societies of Biological Psychiatry.

In the 12 years since the publication of the first Consensus Paper of the WFSBP on biomarkers of neurodegenerative dementias, enormous advancement has taken place in the field, and the Task Force takes now the opportunity to extend and update the original paper. New concepts of Alzheimer's disease (AD) and the conceptual interactions between AD and dementia due to AD were developed, resulting in two sets for diagnostic/research criteria. Procedures for pre-analytical sample handling, biobanking, analyses and post-analytical interpretation of the results were intensively studied and optimised. A global quality control project was introduced to evaluate and monitor the inter-centre variability in measurements with the goal of harmonisation of results. Contexts of use and how to approach candidate biomarkers in biological specimens other than cerebrospinal fluid (CSF), e.g. blood, were precisely defined. Important development was achieved in neuroimaging techniques, including studies comparing amyloid-ß positron emission tomography results to fluid-based modalities. Similarly, development in research laboratory technologies, such as ultra-sensitive methods, raises our hopes to further improve analytical and diagnostic accuracy of classic and novel candidate biomarkers. Synergistically, advancement in clinical trials of anti-dementia therapies energises and motivates the efforts to find and optimise the most reliable early diagnostic modalities. Finally, the first studies were published addressing the potential of cost-effectiveness of the biomarkers-based diagnosis of neurodegenerative disorders.

Towards injectable cell-based tissue-engineered bone: the effect of different calcium phosphate microparticles and pre-culturing.

Bone tissue engineering by combining bone marrow stromal cells (BMSCs) with a porous scaffold is a promising technology. Current major challenges are to upscale the technique for clinical application and to improve the handling characteristics. With respect to minimal invasive surgery, moldable and/or injectable formulations are highly preferable. Ceramic microparticles of different HA/TCP formulations (100/0, 70/30, 60/40, 40/60, and 0/100) with varying surface roughness were sieved to select 200 microg aliquots of the 212-300 microm fraction. Goat BMSCs were seeded on different aliquots one week prior to in vivo implantation. These constructs and remaining cells were cultured for one week. By then, the remaining cells were harvested and resuspended in a specific binder: hyaluronic acid, alginate, or blood plasma, combined with aliquots of 60/40 microparticles peroperatively. All constructs were implanted in nude rats (n = 10) and analyzed for their bone yield histomorphometrically after 6 weeks. All precultured constructs showed consistent bone formation of comparable quantity. No significant differences were observed between the different material compositions. Peroperatively prepared constructs hardly showed any bone formation. The present study demonstrated the osteogenic potential of a tissue- engineered bone substitute made of microparticles of various HA/TCP compositions. There was an obvious advantage when the constructs were pre-cultured.

The battle of Alzheimer's Disease - the beginning of the future Unleashing the potential of academic discoveries.

Alzheimer's Disease (AD) is the most common form of dementia, affecting approximately 36 million people worldwide. To date there is no preventive or curative treatment available for AD, and in absence of major progress in therapeutic development, AD manifests a concrete socioeconomic threat. The awareness of the growing problem of AD is increasing, exemplified by the recent G8 Dementia Summit, a meeting held in order to set the stage and steer the compass for the future. Simultaneously, and paradoxically, we have seen key players in the pharmaceutical industry that have recently closed or significantly decreased their R&D spending on AD and other CNS disorders. Given the pressing need for new treatments in this area, other actors need to step-in and enter this drug discovery arena complementing the industrial efforts, in order to turn biological and technological progress into novel therapeutics. In this article, we present an example of a novel drug discovery initiative that in a non-profit setting, aims to integrate with both preclinical and clinical academic groups and pharmaceutical industry to explore the therapeutic potential of new concepts in patients, using novel biology, state of the art technologies and rapid concept testing.

Massage therapy in post-operative rehabilitation of children and adolescents with cerebral palsy - a pilot study.

AIM: The purpose of this pilot study was to explore the use of massage therapy in children with cerebral palsy undergoing post-operative rehabilitation. MATERIAL AND METHOD: Three participants were randomized to massage therapy and another three participants to rest. All children had undergone surgery in one or two lower limbs. Pain, wellbeing, sleep quality, heart rate and qualitative data were collected for each child. RESULTS: The scores of pain intensity and discomfort were low in all participants. Heart rate decreased in participants who were randomized to rest, but no change was found in the massage therapy group. CONCLUSIONS: The lack of decrease in heart rate in the study group of massage therapy may imply an increased sensitivity to touch in the post-operative setting. Further research with larger study populations are needed to evaluate how and when massage therapy is useful for children with cerebral palsy.
