- Older adults have multiple medical and social care needs, requiring a shift toward an integrated person-centered model of care. Our objective was to describe and summarize Swedish experiences of integrated person-centered care by reviewing studies published between 2000 and 2023, and to identify the main challenges and scientific gaps through expert discussions. Seventy-three publications were identified by searching MEDLINE and contacting experts. Interventions were categorized using two World Health Organization frameworks: (1) Integrated Care for Older People (ICOPE), and (2) Integrated People-Centered Health Services (IPCHS). The included 73 publications were derived from 31 unique and heterogeneous interventions pertaining mainly to the micro- and meso-levels. Among publications measuring mortality, 15% were effective. Subjective health outcomes showed improvement in 24% of publications, morbidity outcomes in 42%, disability outcomes in 48%, and service utilization outcomes in 58%. Workshop discussions in Stockholm (Sweden), March 2023, were recorded, transcribed, and summarized. Experts emphasized: (1) lack of rigorous evaluation methods, (2) need for participatory designs, (3) scarcity of macro-level interventions, and (4) importance of transitioning from person- to people-centered integrated care. These challenges could explain the unexpected weak beneficial effects of the interventions on health outcomes, whereas service utilization outcomes were more positively impacted. Finally, we derived a list of recommendations, including the need to engage care organizations in interventions from their inception and to leverage researchers’ scientific expertise. Although this review provides a comprehensive snapshot of interventions in the context of Sweden, the findings offer transferable perspectives on the real-world challenges encountered in this field.

- Objective To explore the differential associations of neurodegeneration and microvascular lesion load with cognitive decline and dementia in older people and the modifying effect of the APOE genotype on these associations. Methods A sample of 436 participants (age >= 60 years) was derived from the population-based Swedish National study on Aging and Care in Kungsholmen, Stockholm, and clinically examined at baseline (2001-2003) and 3 occasions during the 9-year follow-up. At baseline, we assessed microvascular lesion load using a summary score for MRI markers of lacunes, white matter hyperintensities (WMHs), and perivascular spaces and neurodegeneration load for markers of enlarged ventricles, smaller hippocampus, and smaller gray matter. We assessed cognitive function using the Mini-Mental State Examination (MMSE) test and diagnosed dementia following the Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria. We analyzed data using linear mixed-effects, mediation, and random-effects Cox models. Results During the follow-up, 46 participants were diagnosed with dementia. Per 1-point increase in microvascular lesion and neurodegeneration score (range 0-3) was associated with multiple adjusted beta-coefficients of -0.35 (95% confidence interval, -0.51 to -0.20) and -0.44 (-0.56 to -0.32), respectively, for the MMSE score and multiple adjusted hazard ratios of 1.68 (1.12-2.51) and 2.35 (1.58-3.52), respectively, for dementia; carrying APOE epsilon 4 reinforced the associations with MMSE decline. WMH volume changes during the follow-up mediated 66.9% and 12.7% of the total association of MMSE decline with the baseline microvascular score and neurodegeneration score, respectively. Conclusions Both cerebral microvascular lesion and neurodegeneration loads are strongly associated with cognitive decline and dementia. The cognitive decline due to microvascular lesions is exacerbated by APOE epsilon 4 and is largely attributed to progression and development of microvascular lesions.

Tidskriftsartikel (refereegranskat)abstract
- Background: Vitamin E includes eight natural antioxidant compounds (four tocopherols and four tocotrienols), but a-tocopherol has been the main focus of investigation in studies of cognitive impairment and Alzheimer's disease. Objective: To investigate the association between serum levels of tocopherols and tocotrienols, markers of vitamin E oxidative/nitrosative damage (alpha-tocopherylquinone, 5-nitro-gamma-tocopherol) and incidence of cognitive impairment in a population-based study. Design: A sample of 140 non-cognitively impaired elderly subjects derived from the Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) study was followed-up for 8 years to detect cognitive impairment, defined as development of mild cognitive impairment (MCI) or Alzheimer's dementia. The association between baseline serum vitamin E and cognitive impairment was analyzed with multiple logistic regression after adjusting for several confounders. Results: The risk of cognitive impairment was lower in subjects in the middle tertile of the alpha-tocopherol/cholesterol ratio than in those in the lowest tertile: the multiadjusted odds ratio (OR) with 95% confidence interval (CI) was 0.27 (0.10-0.78). Higher incidence of cognitive impairment was found in the middle [OR (95% CI): 3.41 (1.29-9.06)] and highest [OR (95% CI): 2.89 (1.05-7.97)] tertiles of the 5-NO2-gamma-tocopherol/gamma-tocopherol ratio. Analyses of absolute serum levels of vitamin E showed lower risk of cognitive impairment in subjects with higher levels of gamma-tocopherol, beta-tocotrienol, and total tocotrienols. Conclusions: Elevated levels of tocopherol and tocotrienol forms are associated with reduced risk of cognitive impairment in older adults. The association is modulated by concurrent cholesterol concentration. Various vitamin E forms might play a role in cognitive impairment, and their evaluation can provide a more accurate measure of vitamin E status in humans.

- The concepts of target efficiency can be used to assess the extent to which service provision is in line with the needs of the population. Horizontal target efficiency denotes the extent to which those deemed to need a service receive it and vertical target efficiency is the corresponding extent to which those who receive services actually need them. The aim of this study was to assess the target efficiency of the Swedish eldercare system and to establish whether target efficiencies differ in different geographical areas such as large urban, midsize urban and rural areas. Vertical efficiency was measured by studying those people who received eldercare services and was expressed as a percentage of those who received services who were functionally dependent. To measure horizontal target efficiency, data collected at baseline in the longitudinal population study SNAC (Swedish National study on Aging and Care) during the years 2001-2004 were used. The horizontal efficiency was calculated as the percentage of functionally dependent persons who received services. Functional dependency was measured as having difficulty with instrumental activities of daily living (IADL) and/or personal activities of daily living (PADL). Services included long-term municipal eldercare services (LTC). Horizontal target efficiency for the public LTC system was reasonably high in all three geographical areas, when using dependency in PADL as the measure of need (70-90 %), but efficiency was lower when the less restrictive measure of IADL dependency was used (40-50 %). In both cases, the target efficiency was markedly higher in the large urban and the rural areas than in the midsize urban areas. Vertical target efficiency showed the same pattern-it was almost 100 % in all areas for IADL dependency, but only 50-60 % for PADL dependency. Household composition differed in the areas studied as did the way public long-term care was provided to people living alone as compared to those co-habiting.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To explore the association between cardiovascular risk factor (CRF) burden and limitation in walking speed, balance, and chair stand and to verify whether these associations vary according to age and cognitive status.DESIGN: Longitudinal population-based study.SETTING: Urban area of Stockholm, Sweden.PARTICIPANTS: Individuals aged 60 and older who participated in the Swedish National Study on Aging and Care in Kungsholmen and were free of limitations in walking speed (n = 1,441), balance (n = 1,154), or chair stands (n = 1,496) at baseline (2001-04).MEASUREMENTS: At baseline, data on demographic characteristics, CRFs, other lifestyle factors, C-reactive protein, and cognitive function were collected. CRF burden was measured using the Framingham general cardiovascular risk score (FRS). Limitations in walking speed (<0.8 m/s), balance (<5 seconds), and chair stand (inability to rise 5 times) were determined at 3-, 6-, and 9-year follow-up. Data were analyzed using Cox proportional hazards models stratified according to age (<78, >= 78).RESULTS: During follow-up, 326 persons developed limitations in walking speed, 303 in balance, and 374 in chair stands. An association between the FRS and walking speed limitation was evident only in adults younger than 78 (for each 1-point increase in FRS: hazard ratio (HR) = 1.09, 95% confidence interval (CI) = 1.02-1.17) after controlling for potential confounders including cognitive function (correspondingly, in adults aged >= 78: HR = 0.98, 95% CI = 0.92-1.03). Also, higher FRS was significantly associated with faster decline in walking speed (P<.001).CONCLUSION: A higher FRS is associated with greater risk of subsequent development of walking speed limitation in adults younger than 78, independent of cognitive function. Interventions targeting multiple CRFs in younger-old people may help in maintaining mobility function.

Tidskriftsartikel (refereegranskat)abstract
- Dementia is an increasing focus for policymakers, civil organizations and multidisciplinary researchers. The most recent descriptive epidemiological research into dementia is enabling investigation into how the prevalence and incidence are changing over time. To establish clear trends, such comparisons need to be founded on population-based studies that use similar diagnostic and research methods consistently over time. This narrative Review synthesizes the findings from 14 studies that investigated trends in dementia prevalence (nine studies) and incidence (five studies) from Sweden, Spain, the UK, the Netherlands, France, the USA, Japan and Nigeria. Besides the Japanese study, these studies indicate stable or declining prevalence and incidence of dementia, and some provide evidence of sex-specific changes. No single risk or protective factor has been identified that fully explains the observed trends, but major societal changes and improvements in living conditions, education and healthcare might have favourably influenced physical, mental and cognitive health throughout an individual's life course, and could be responsible for a reduced risk of dementia in later life. Analytical epidemiological approaches combined with translational neuroscientific research could provide a unique opportunity to explore the neuropathology that underlies changing occurrence of dementia in the general population.

Is Midlife Occupational Physical Activity Related to Disability in Old Age? The SNAC-Kungsholmen Study
- 2013
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 8:7
-
Tidskriftsartikel (refereegranskat)abstract
- Objectives: Leisure-time physical activity (PA) has been established to be related to more years lived without disability. However, less is known about the relationship between occupational PA and disability in old age. The aim of the study was 1) to investigate whether midlife occupational PA is related to late-life disability, and 2) to test the hypothesis that the association differs according to the occupational categories of blue and white collar work. Methods: The study population was derived from the Swedish National Study on Aging and Care, and consisted of a random sample of 1804 subjects aged 72 and above. The association of occupational PA during the longest held occupation with disability in old age was determined using logistic regression. Results: There was no significant relationship between occupational PA and disability in personal or instrumental activities of daily living (ADL) after controlling for demographic and health-related factors. However, in stratified analyses moderate levels of occupational PA was associated with a lower odds ratio of dependency in personal ADL amongst white collar workers, compared to low level of occupational PA (OR = 0.34 95% C1 0.12-0.98). Conclusions: Moderate levels of midlife occupational PA were associated with a decreased risk of personal ADL disability in old age among white collar workers, but not among blue collar workers. Our results highlight the importance of encouraging white collar workers to engage in physical activity during or outside work hours.

Tidskriftsartikel (refereegranskat)abstract
- The extent to which a system of services is in tune with the needs of the population can be expressed in terms of target efficiency, which includes horizontal target efficiency - the extent to which those deemed to need a service receive it - and vertical target efficiency - the corresponding extent to which those who receive a service actually need it. Vertical efficiency can be measured by looking only at those receiving services. To measure horizontal target efficiency in a population, one must have access to population surveys. Data were taken from the baseline survey of the Swedish National Study on Ageing and Care (SNAC study). The results show that more than 80 per cent of those dependent in personal activities of daily living in the studied geographic areas were users of public long-term care (LTC). Dependency in instrumental activities of daily living was identified as the most important predictor of using LTC. Vertical target efficiency was 83-95 per cent depending on age, gender and type of household, if need was defined as dependency in instrumental activities of daily living. It was considerably lower, 35-61 per cent when defined as dependency in personal daily activities. Overall, long-term target efficiency in Sweden must be regarded as high. Few persons who need public LTC services fail to receive them.

Amyloid β-protein, Cystatin C and Cathepsin B as Biomarkers of Alzheimer's Disease
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It is suggested that Alzheimer’s disease (AD) is caused by an imbalance between production, degradation and clearance of the amyloid-β (Aβ) protein. This imbalance leads to aggregation of Aβ and tau proteins and neurodegeneration in the brain. Today there is increasing evidence that the balance between the protease cathepsin B and the protease inhibitor cystatin C affects the tendency for Aβ to aggregate. The primary aim of this thesis was to investigate Aβ, cystatin C and cathepsin B levels in blood and cerebro-spinal fluid (CSF) in relation to the risk of AD.Studies I & II were based on the re-examinations of participants, at ages 70 and 77, in the Uppsala Longitudinal Study of Adult Men (ULSAM), a community-based prospective study initiated in 1970 (participants then being 50 years of age). In ULSAM, low plasma Aβ1-40 (Study I) and low serum cystatin C levels (Study II) were associated with a higher risk of AD. Studies III & IV were based on a cross-sectional sample of people with AD, mild cognitive impairment and healthy controls, recruited at three Swedish Memory Disorder units: Uppsala University Hospital, Uppsala, Skåne University Hospital, Malmö, and Karolinska University Hospital, Huddinge, Stockholm. In Study III, CSF cystatin C levels were positively correlated with both Aβ1-42 and tau levels. In Study IV, individuals with AD had higher mean plasma cathepsin B levels than healthy controls.In conclusion, low plasma Aβ1-40 and low serum cystatin C levels may precede clinically manifest AD in elderly men, cystatin C levels are positively correlated with Aβ1-42 and tau levels in CSF, and mean plasma cathepsin B levels are higher in people with AD compared to healthy controls. In addition to Aβ1-42 and tau levels in CSF, Aβ1-40, cystatin C and cathepsin B levels in blood may reflect the risk of AD.

Tidskriftsartikel (refereegranskat)abstract
- Background: Inappropriate drug use (IDU) is an important risk factor for adverse outcomes in older persons. We aimed to investigate IDU and the risk of hospitalizations and mortality in older persons and in persons with dementia and to estimate the costs of IDU-related hospitalizations.Methods: We analyzed 4108 individuals aged a parts per thousand yen60 years from the Swedish National Study on Aging and Care (SNAC) data from Kungsholmen and Nordanstig (2001-2004). IDU was assessed by indicators developed by the Swedish National Board of Health and Welfare. Hospitalizations and mortality data were collected from Swedish registers. Regression models were used to investigate associations between IDU, hospitalizations, and mortality in the whole population and in the subpopulation of persons with dementia (n = 319), after adjustment for sociodemographics, physical functioning, and co-morbidity. Costs for hospitalizations were derived from the Nord-Diagnose Related Group cost database. Results IDU was associated with a higher risk of hospitalization [adjusted odds ratio (OR) = 1.46; 95 % confidence interval (CI) 1.18-1.81] and mortality [adjusted hazard ratio (HR) = 1.15; 95 % CI 1.01-1.31] within 1 year in the whole study population and with hospitalization (adjusted OR = 1.88; 95 % CI 1.03-3.43) in the subpopulation of persons with dementia, after adjustment for confounding factors. There was also a tendency for higher costs for hospitalizations with IDU than without IDU, although this was not statistically significant.Conclusions: Our findings suggest that IDU is associated with an increased risk of hospitalization in older persons and in persons with dementia. IDU is also associated with mortality among older persons. These findings highlight the need for cautious prescribing of long-acting benzodiazepines, anticholinergic drugs, concurrent use of three or more psychotropic drugs and drug combinations that may lead to serious drug-drug interactions to older patients. Further studies are needed to investigate the association between IDU and costs for hospitalizations.
