Treatment of cardiovascular risk factors to prevent cognitive decline and dementia: a systematic review

Suzanne A Ligthart1, Eric P Moll van Charante1, Willem A Van Gool2, Edo Richard21Department of General Practice, 2Department of Neurology, Academic Medical Center, University of Amsterdam, Amsterdam, The NetherlandsBackground: Over the last decade, evidence has accumulated that vascular risk factors increase the risk of Alzheimer disease (AD). So far, few randomized controlled trials have focused on lowering the vascular risk profile to prevent or postpone cognitive decline or dementia.Objective: To systematically perform a review of randomized controlled trials (RCTs) evaluating drug treatment effects for cardiovascular risk factors on the incidence of dementia or cognitive decline.Selection criteria: RCTs studying the effect of treating hypertension, dyslipidemia, ­hyperhomocysteinemia, obesity, or diabetes mellitus (DM) on cognitive decline or dementia, with a minimum follow-up of 1 year in elderly populations.Outcome measure: Cognitive decline or incident dementia.Main results: In the identified studies, dementia was never the primary outcome. Statins (2 studies) and intensified control of type II DM (1 study) appear to have no effect on prevention of cognitive decline. Studies on treatment of obesity are lacking, and the results of lowering homocysteine (6 studies) are inconclusive. There is some evidence of a preventive effect of antihypertensive medication (6 studies), but results are inconsistent.Conclusion: The evidence of a preventive treatment effect aimed at vascular risk factors on cognitive decline and dementia in later life is scarce and mostly based on secondary outcome parameters. Several important sources of bias such as differential dropout may importantly affect interpretation of trial results.Keywords: cardiovascular risk factors, cognitive decline, dementia, preventio

Natriuretic peptides and integrated risk assessment for cardiovascular disease: an individual-participant-data meta-analysis

BACKGROUND: Guidelines for primary prevention of cardiovascular diseases focus on prediction of coronary heart disease and stroke. We assessed whether or not measurement of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) concentration could enable a more integrated approach than at present by predicting heart failure and enhancing coronary heart disease and stroke risk assessment. METHODS: In this individual-participant-data meta-analysis, we generated and harmonised individual-participant data from relevant prospective studies via both de-novo NT-proBNP concentration measurement of stored samples and collection of data from studies identified through a systematic search of the literature (PubMed, Scientific Citation Index Expanded, and Embase) for articles published up to Sept 4, 2014, using search terms related to natriuretic peptide family members and the primary outcomes, with no language restrictions. We calculated risk ratios and measures of risk discrimination and reclassification across predicted 10 year risk categories (ie, <5%, 5% to <7·5%, and ≥7·5%), adding assessment of NT-proBNP concentration to that of conventional risk factors (ie, age, sex, smoking status, systolic blood pressure, history of diabetes, and total and HDL cholesterol concentrations). Primary outcomes were the combination of coronary heart disease and stroke, and the combination of coronary heart disease, stroke, and heart failure. FINDINGS: We recorded 5500 coronary heart disease, 4002 stroke, and 2212 heart failure outcomes among 95 617 participants without a history of cardiovascular disease in 40 prospective studies. Risk ratios (for a comparison of the top third vs bottom third of NT-proBNP concentrations, adjusted for conventional risk factors) were 1·76 (95% CI 1·56-1·98) for the combination of coronary heart disease and stroke and 2·00 (1·77-2·26) for the combination of coronary heart disease, stroke, and heart failure. Addition of information about NT-proBNP concentration to a model containing conventional risk factors was associated with a C-index increase of 0·012 (0·010-0·014) and a net reclassification improvement of 0·027 (0·019-0·036) for the combination of coronary heart disease and stroke and a C-index increase of 0·019 (0·016-0·022) and a net reclassification improvement of 0·028 (0·019-0·038) for the combination of coronary heart disease, stroke, and heart failure. INTERPRETATION: In people without baseline cardiovascular disease, NT-proBNP concentration assessment strongly predicted first-onset heart failure and augmented coronary heart disease and stroke prediction, suggesting that NT-proBNP concentration assessment could be used to integrate heart failure into cardiovascular disease primary prevention.

Integrated dementia care in The Netherlands: a multiple case study of case management programmes

The number of dementia patients is growing, and they require a variety of services, making integrated care essential for the ability to continue living in the community. Many healthcare systems in developed countries are exploring new approaches for delivering health and social care. The purpose of this study was to describe and analyse a new approach in extensive case management programmes concerned with long-term dementia care in The Netherlands. The focus is on the characteristics, and success and failure factors of these programmes.A multiple case study was conducted in eight regional dementia care provider networks in The Netherlands. Based on a literature study, a questionnaire was developed for the responsible managers and case managers of the eight case management programmes. During 16 semistructured face-to-face interviews with both respondent groups, a deeper insight into the dementia care programmes was provided. Project documentation for all the cases was studied. The eight programmes were developed independently to improve the quality and continuity of long-term dementia care. The programmes show overlap in terms of their vision, tasks of case managers, case management process and the participating partners in the local dementia care networks. Differences concern the targeted dementia patient groups as well as the background of the case managers and their position in the local dementia care provider network. Factors for success concern the expert knowledge of case managers, investment in a strong provider network and coherent conditions for effective inter-organizational cooperation to deliver integrated care. When explored, caregiver and patient satisfaction was high. Further research into the effects on client outcomes, service use and costs is recommended in order to further analyse the impact of this approach in long-term care. To facilitate implementation, with a focus on joint responsibilities of the involved care providers, policy recommendations are to develop incentives for collaborative financial contracts between insurers and provider

Cardiovascular risk management in community-dwelling elderly: opportunities for prevention

Background: There is little information on the prevalence of hypertension and other modifiable cardiovascular risk factors in community-dwelling elderly in the Netherlands and the potential impact of improving antihypertensive treatment on major cardiovascular events. Design: Cross-sectional analysis of Dutch community-dwelling subjects aged 70-78 years without dementia who were included in the cluster randomized preDIVA trial (Prevention of Dementia by Intensive Vascular care). Methods: The prevalence of hypertension and other cardiovascular risk factors are described for participants with and without a history of cardiovascular disease (CVD). Projected benefits of blood pressure decrease are calculated using data from a meta-analysis and a large national registry. Results: Of 3534 subjects, more than one-third (n = 1230, 35.2%) have a history of cardiovascular disease. Overall, 63% of subjects have two or more cardiovascular risk factors amenable to treatment. Systolic blood pressure (SBP) is >= 160mmHg in 37% of patients with CVD, of which 28% is untreated. In subjects without a history of CVD, 41% have a SBP >= 160mmHg of which 52% is untreated. A 5-15mmHg decrease in SBP is projected to prevent 12-32% of coronary heart disease and 16-41% of strokes, respectively. This corresponds with 14-38 prevented cases within 2 years in our intervention group (n = 1895). Conclusions: Hypertension and other cardiovascular risk factors are very common in elderly subjects. Current (primary and secondary) prevention programmes appear insufficient. Improved antihypertensive treatment has the potential to prevent a substantial proportion of strokes and coronary heart disease in this populatio

Antidepressiva bij depressie: rationeel voorschrijven

Antidepressants are the subject of lively public debate. Over one million Dutch people are prescribed an antidepressant each year for a variety of reasons. The number of long-term antidepressant users is smaller, estimated to be around 150,000 patients for over a year for depression. Clinicians and patients together must carefully weigh the pros and cons of antidepressants. In this article, we discuss the latest scientific insights how antidepressants can be used rationally

Key Factors in Helpfulness and Use of the SAFE Intervention for Women Experiencing Intimate Partner Violence and Abuse: Qualitative Outcomes From a Randomized Controlled Trial and Process Evaluation

BackgroundMany women experience at least one type of intimate partner violence and abuse (IPVA), and although various support options are available, we still know relatively little about web-based interventions for IPVA survivors. We conducted a qualitative evaluation of the SAFE eHealth intervention for women experiencing IPVA in the Netherlands, complementing the quantitative evaluation of self-efficacy, depression, anxiety, and multiple feasibility aspects. ObjectiveThis study assessed users’ experiences and what, according to them, were useful and helpful aspects of the intervention. MethodsThe intervention consisted of modules with information on relationships and IPVA, help options, physical and mental health, and social support. It also contained interactive elements such as exercises, stories from survivors, a chat, and a forum. A randomized controlled trial was conducted with an intervention arm receiving the complete version of the intervention and a control arm receiving only a static version with the modules on relationships and IPVA and help options. We gathered data through open questions from surveys (for both study arms; n=65) and semistructured interviews (for the intervention study arm; n=10), all conducted on the web, during the randomized controlled trial and process evaluation. Interview data were coded following the principles of open thematic coding, and all qualitative data were analyzed using qualitative content analysis. ResultsOverall, most users positively rated the intervention regarding safety, content, and suiting their needs, especially participants from the intervention study arm. The intervention was helpful in the domains of acknowledgment, awareness, and support. However, participants also identified points for improvement: the availability of a simplified version for acute situations; more attention for survivors in the aftermath of ending an abusive relationship; and more information on certain topics, such as technological IPVA, support for children, and legal affairs. Furthermore, although participants expressed a prominent need for interactive contact options such as a chat or forum, the intervention study arm (the only group that had these features at their disposal) mainly used them in a passive way—reading instead of actively joining the conversation. The participants provided various reasons for this passive use. ConclusionsThe positive outcomes of this study are similar to those of other web-based interventions for IPVA survivors, and specific points for improvement were identified. The availability of interactive elements seems to be of added value even when they are used passively. This study provides in-depth insight into the experiences of female IPVA survivors with the SAFE eHealth intervention and makes suggestions for improvements to SAFE and comparable web-based interventions for IPVA as well as inspiring future research. Furthermore, this study shows the importance of a varied assessment of an intervention’s effectiveness to understand the real-world impact on its users.

Effectiveness of the SAFE eHealth Intervention for Women Experiencing Intimate Partner Violence and Abuse: Randomized Controlled Trial, Quantitative Process Evaluation, and Open Feasibility Study (Preprint)

van Gelder NE, Ligthart SA, van Rosmalen-Nooijens KAWL, Prins JB, Oertelt-Prigione S. Effectiveness of the SAFE eHealth Intervention for Women Experiencing Intimate Partner Violence and Abuse: Randomized Controlled Trial, Quantitative Process Evaluation, and Open Feasibility Study (Preprint). 2022.Background: Introduction: Intimate partner violence and abuse (IPVA) is a pervasive societal issue that impacts many women globally. Online help options are becoming increasingly available and have the ability to eliminate certain barriers in help seeking for IPVA, especially in improving accessibility. Objective: This study focused on the quantitative evaluation of the SAFE eHealth intervention for women IPVA survivors. Methods: 198 women that experienced IPVA participated in a randomized controlled trial (RCT). They were allocated to (a) the intervention group with access to a complete version of a help-website with interactive components or (b) to the limited-intervention control group. Data was gathered about self-efficacy, depression, anxiety, and multiple feasibility aspects. The primary outcome was self-efficacy at six months. In an open feasibility study (OFS; N=170), we assessed demand, implementation and practicality. Results: We found no significant difference over time between groups for self-efficacy, depression, anxiety, fear of partner, awareness and perceived support. However, both study arms showed significantly decreased scores for anxiety and fear of partner. Most participants in both groups were satisfied, but the intervention group showed significantly higher scores for suitability and feeling helped. Furthermore, the intervention was positively evaluated on multiple feasibility aspects. An increase of registrations during the OFS was found. Conclusions: Our findings did not show a significant difference in outcomes between the extensive SAFE intervention compared to the limited-intervention control group. It is, however, difficult to quantify the real contribution of the interactive components, as the control group also had access to a limited version of the intervention for ethical reasons. Both groups were satisfied with the intervention they received, with the intervention study arm significantly more so than the control study arm. Integrated and multi-layered approaches are needed to aptly quantify the impact of online IPVA interventions for survivors

Effectiveness of the SAFE eHealth Intervention for Women Experiencing Intimate Partner Violence and Abuse: Randomized Controlled Trial, Quantitative Process Evaluation, and Open Feasibility Study. Journal of Medical Internet Research. 2023;25: e42641.**Background** Intimate partner violence and abuse (IPVA) is a pervasive societal issue that impacts many women globally. Web-based help options are becoming increasingly available and have the ability to eliminate certain barriers in help seeking for IPVA, especially in improving accessibility. **Objective** This study focused on the quantitative evaluation of the SAFE eHealth intervention for women IPVA survivors. **Methods** A total of 198 women who experienced IPVA participated in a randomized controlled trial and quantitative process evaluation. Participants were largely recruited on the internet and signed up through self-referral. They were allocated (blinded for the participants) to (1) the intervention group (N=99) with access to a complete version of a help website containing 4 modules on IPVA, support options, mental health, and social support, and with interactive components such as a chat, or (2) the limited-intervention control group (N=99). Data were gathered about self-efficacy, depression, anxiety, and multiple feasibility aspects. The primary outcome was self-efficacy at 6 months. The process evaluation focused on themes, such as ease of use and feeling helped. In an open feasibility study (OFS; N=170), we assessed demand, implementation, and practicality. All data for this study were collected through web-based self-report questionnaires and automatically registered web-based data such as page visits and amount of logins. **Results** We found no significant difference over time between groups for self-efficacy, depression, anxiety, fear of partner, awareness, and perceived support. However, both study arms showed significantly decreased scores for anxiety and fear of partner. Most participants in both groups were satisfied, but the intervention group showed significantly higher scores for suitability and feeling helped. However, we encountered high attrition for the follow-up surveys. Furthermore, the intervention was positively evaluated on multiple feasibility aspects. The average amount of logins did not significantly differ between the study arms, but participants in the intervention arm did spend significantly more time on the website. An increase in registrations during the OFS (N=170) was identified: the mean amount of registrations per month was 13.2 during the randomized controlled trial and 56.7 during the OFS. **Conclusions** Our findings did not show a significant difference in outcomes between the extensive SAFE intervention and the limited-intervention control group. It is, however, difficult to quantify the real contribution of the interactive components, as the control group also had access to a limited version of the intervention for ethical reasons. Both groups were satisfied with the intervention they received, with the intervention study arm significantly more so than the control study arm. Integrated and multilayered approaches are needed to aptly quantify the impact of web-based IPVA interventions for survivors. **Trial Registration** Netherlands Trial Register NL7108 NTR7313; https://trialsearch.who.int/Trial2.aspx?TrialID=NTR731
