    • Background: Web-based interventions can improve single cardiovascular risk factors in adult populations. In view of global aging and the associated increasing burden of cardiovascular disease, older people form an important target population as well.Objective: In this systematic review and meta-analysis, we evaluated whether Web-based interventions for cardiovascular risk factor management reduce the risk of cardiovascular disease in older people.Methods: Embase, Medline, Cochrane and CINAHL were systematically searched from January 1995 to November 2014. Search terms included cardiovascular risk factors and diseases (specified), Web-based interventions (and synonyms) and randomized controlled trial. Two authors independently performed study selection, data-extraction and risk of bias assessment. In a meta-analysis, outcomes regarding treatment effects on cardiovascular risk factors (blood pressure, glycated hemoglobin A1c (HbA1C), low-density lipoprotein (LDL) cholesterol, smoking status, weight and physical inactivity) and incident cardiovascular disease were pooled with random effects models.Results: A total of 57 studies (N=19,862) fulfilled eligibility criteria and 47 studies contributed to the meta-analysis. A significant reduction in systolic blood pressure (mean difference -2.66 mmHg, 95% CI -3.81 to -1.52), diastolic blood pressure (mean difference -1.26 mmHg, 95% CI -1.92 to -0.60), HbA1c level (mean difference -0.13%, 95% CI -0.22 to -0.05), LDL cholesterol level (mean difference -2.18 mg/dL, 95% CI -3.96 to -0.41), weight (mean difference -1.34 kg, 95% CI -1.91 to -0.77), and an increase of physical activity (standardized mean difference 0.25, 95% CI 0.10-0.39) in the Web-based intervention group was found. The observed effects were more pronounced in studies with short (<12 months) follow-up and studies that combined the Internet application with human support (blended care). No difference in incident cardiovascular disease was found between groups (6 studies).Conclusions: Web-based interventions have the potential to improve the cardiovascular risk profile of older people, but the effects are modest and decline with time. Currently, there is insufficient evidence for an effect on incident cardiovascular disease. A focus on long-term effects, clinical endpoints, and strategies to increase sustainability of treatment effects is recommended for future studies.

  • Future directions in Alzheimer's disease from risk factors to prevention
  • 2014
  • Ingår i: Biochemical Pharmacology. - : Elsevier BV. - 0006-2952 .- 1356-1839 .- 1873-2968. ; 88:4, s. 661-670

    • The increase in life expectancy has resulted in a high occurrence of dementia and Alzheimer's disease (AD). Research on AD has undergone a paradigm shift from viewing it as a disease of old age to taking a life course perspective. Several vascular, lifestyle, psychological and genetic risk factors influencing this latent period have been recognized and they may act both independently and by potentiating each other. These risk factors have consequently been used to derive risk scores for predicting the likelihood of dementia. Despite population differences, age, low education and vascular risk factors were identified as key factors in all scoring systems. Risk scores can help to identify high-risk individuals who might benefit from different interventions. The European Dementia Prevention Initiative (EDPI), an international collaboration, encourages data sharing between different randomized controlled trials. At the moment, it includes three large ongoing European trials: Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER), Prevention of Dementia by Intensive Vascular Care (preDIVA), and Multidomain Alzheimer Prevention study (MAPT). Recently EDPI has developed a Healthy Aging through Internet Counseling in Elderly (HATICE) program, which intends to manage modifiable risk factors in an aged population through an easily accessible Internet platform. Thus, the focus of dementia research has shifted from identification of potential risk factors to using this information for developing interventions to prevent or delay the onset of dementia as well as identifying special high-risk populations who could be targeted in intervention trials.

  • Emerging role of p62/sequestosome-1 in the pathogenesis of Alzheimer's disease
  • 2012
  • Ingår i: Progress in Neurobiology. - : Elsevier BV. - 0301-0082 .- 1873-5118. ; 96:1, s. 87-95

    • The p62/sequestosome-1 is a multifunctional protein containing several protein-protein interaction domains. Through these interactions p62 is involved in the regulation of cellular signaling and protein trafficking, aggregation and degradation. p62 protein can bind through its UBA motif to ubiquitinated proteins and control their aggregation and degradation via either autophagy or proteasomes. p62 protein has been reported to be seen in association with the intracellular inclusions in primary and secondary tauopathies, α-synucleinopathies and other neurodegenerative brain disorders displaying inclusions with misfolded proteins. In Alzheimer's disease (AD), p62 protein is associated with neurofibrillary tangles composed primarily of hyperphosphorylated tau protein and ubiquitin. Increasing evidence indicates that p62 has an important role in the degradation of tau protein. The lack of p62 protein expression provokes the tau pathology in mice. Recent studies have demonstrated that the p62 gene expression and cytoplasmic p62 protein levels are significantly reduced in the frontal cortex of AD patients. Decline in the level of p62 protein can disturb the signaling pathways of Nrf2, cyclic AMP and NF-κB and in that way increase oxidative stress and impair neuronal survival. We will review here the molecular and functional characteristics of p62 protein and outline its potential role in the regulation of Alzheimer's pathogenesis.

  • Prevention of Alzheimer's Disease : Backward through the Lifespan
  • 2013
  • Ingår i: Journal of Alzheimer's Disease. - 1387-2877 .- 1875-8908. ; 33, s. s465-S469

    • This is a brief summary of experiences from Finland related to Alzheimer's disease (AD) prevention research. The first signals that AD may have vascular modifiable risk factors came from studies on cardiovascular conditions and diabetes. Cardiovascular prevention projects such as North Karelia Project and WHO-MONICA in the 1970-1980s were focused on younger populations, which led to the idea of looking for risk factors as far back as middle age. Cardiovascular Risk Factors, Aging and Incidence of Dementia (CAIDE) is one of the few studies in the world focusing on late-life cognition with a large and representative population-based cohort, baseline examination at midlife, and follow-up time up to three decades. Since 1998, it has identified several modifiable risk factors for cognitive impairment/dementia, and produced the first risk score for estimating dementia risk based on midlife profiles. The CAIDE Dementia Risk Score has been used to select participants in the Finnish Geriatric Intervention Study to prevent cognitive impairment and disability (FINGER). FINGER is an ongoing multicenter RCT involving 1,200 participants aged 60-77 years, and testing the effects of a two-year multi-domain intervention targeting several risk factors simultaneously. It started in September 2009 and will be completed at the end of 2013. The FINGER study is at the forefront of international collaborative efforts to solve the clinical and public health problems of early identification of individuals at increased risk of late-life cognitive impairment, and of developing intervention strategies to prevent or delay the onset of cognitive impairment and dementia.

  • Forskningsöversikt (refereegranskat)abstract
    • "clinical NEUroPROteomics of neurodegenerative diseases" (cNEUPRO) is a Specific Targeted Research Project (STREP) within the sixth framework program of the European Commission dedicated to the search for novel biomarker candidates for Alzheimer's disease and other neurodegenerative diseases. The ultimate goal of cNEUPRO is to identify one or more valid biomarker(s) in blood and CSF applicable to support the early and differential diagnosis of dementia disorders. The consortium covers all steps required for the discovery of novel biomarker candidates such as acquisition of high quality CSF and blood samples from relevant patient groups and controls, analysis of body fluids by various methods, and finally assay development and assay validation. Here we report the standardized procedures for diagnosis and preanalytical sample-handling within the project, as well as the status of the ongoing research activities and some first results.

  • Midlife Vascular Risk Factors and Alzheimer's Disease : Evidence from Epidemiological Studies
  • 2012
  • Ingår i: Journal of Alzheimer's Disease. - 1387-2877 .- 1875-8908. ; 32:3, s. 531-540
  • Forskningsöversikt (refereegranskat)abstract
    • The shared risk factor profile between cardiovascular diseases and Alzheimer's disease (AD), observations on vascular pathology in AD, and altered cerebral blood flow in AD brains have led to the suggestion that AD might be a vascular disorder with neurodegenerative consequences. Targeting vascular and metabolic risk factors could be an effective way to prevent AD. Higher body mass index, elevated blood pressure, serum cholesterol concentrations, and impaired glucose regulation have been associated with increased risk of AD. Interestingly, the associations between these factors measured at mid-life are stronger, or even opposite, than with the risk factors measured at late-life. This may reflect true differences in the association (i.e., mid-life risk factors being a better measure of vascular load during adulthood), reverse causality, or bias. The vascular risk factors can directly increase the susceptibility to AD, or the effect can be mediated via cardio- and cerebrovascular diseases.
