Effects of an 8-week aerobic exercise program on plasma markers for cholesterol absorption and synthesis in older overweight and obese men.

BACKGROUND: Increased physical activity is inversely related to the risk to develop cardiovascular disease (CVD). In a recent systematic review, it was reported that CVD patients had an increased cholesterol absorption and a decreased synthesis as compared with control participants. As increased physical activity levels reduce CVD risk, we hypothesized that exercise training will reduce cholesterol absorption and increase endogenous cholesterol synthesis in older overweight and obese men. METHODS: A randomized, controlled, crossover trial was performed. Seventeen apparently healthy older overweight and obese men were randomized to start with an aerobic exercise or no-exercise control period for 8 weeks, separated by 12 weeks washout. Fasting serum total cholesterol (TC) and non-cholesterol sterol concentrations were measured at baseline, and after 4 and 8 weeks. RESULTS: The aerobic exercise program did not affect serum TC concentrations. In addition, exercise did not affect TC-standardized serum concentrations of sitosterol and cholestanol that are markers for cholesterol absorption. However, a trend for reduced TC-standardized campesterol concentrations, which is another validated marker for cholesterol absorption, was observed as compared with control. Lathosterol concentrations, reflecting cholesterol synthesis, did not differ between both periods. CONCLUSIONS: Aerobic exercise training for 8 weeks did not lower serum TC concentrations in older overweight and obese men, but a trend towards a decrease in the cholesterol absorption marker campesterol was found. The cholesterol synthesis marker lathosterol did not change. TRIAL REGISTRATION: posted on www.clinicaltrials.gov as NCT03272061 on 7 September 2017.

Pharmacological treatment of increased vascular risk and cognitive performance in middle-aged and old persons: six-year observational longitudinal study.

BACKGROUND: Lowering vascular risk is associated with a decrease in the prevalence of cardiovascular disease and dementia. However, it is still unknown whether lowering of vascular risk with pharmacological treatment preserves cognitive performance in general. Therefore, we compared the change in cognitive performance in persons with and without treatment of vascular risk factors. METHODS: In this longitudinal observational study, 256 persons (mean age, 58 years) were treated for increased vascular risk during a mean follow-up period of 5.5 years (treatment group), whereas 1678 persons (mean age, 50 years) did not receive treatment (control group). Cognitive performance was three times measured during follow-up using the Ruff Figural Fluency Test (RFFT) and Visual Association Test (VAT), and calculated as the average of standardized RFFT and VAT score per participant. Because treatment allocation was nonrandomized, additional analyses were performed in demographic and vascular risk-matched samples and adjusted for propensity scores. RESULTS: In the treatment group, mean (SD) cognitive performance changed from - 0.30 (0.80) to - 0.23 (0.80) to 0.02 (0.87), and in control group, from 0.08 (0.77) to 0.24 (0.79) to 0.49 (0.74) at the first, second and third measurement, respectively (ptrend < 0.001). After adjustment for demographics and vascular risk, the change in cognitive performance during follow-up was not statistically significantly different between the treatment and control group: mean estimated difference, - 0.10 (95%CI - 0.21 to 0.01; p = 0.08). Similar results were found in matched samples and after adjustment for propensity score. CONCLUSION: Change in cognitive performance during follow-up was similar in treated and untreated persons. This suggests that lowering vascular risk preserves cognitive performance.

A good beginning: study protocol for a group-randomized trial to investigate the effects of sit-to-stand desks on academic performance and sedentary time in primary education.

BACKGROUND: Sedentary behavior is associated with health risks and academic under-achievement in children. Still, children spend a large part of their waking hours sitting at a desk at school. Recent short-term studies demonstrated the potential of sit-to-stand desks to reduce sitting time in primary education. The program of "A Good Beginning" was conceived to assess the long-term effects of sit-to-stand desks on sitting time in primary education, and to examine how sit-to-stand desks versus regular desks relate to academic performance, and measures of executive functioning, health and wellbeing. The present paper describes the design of this group-randomized trial, which started in 2017 and will be completed in 2019. METHODS: Children of two grade-three groups (age 8-9) following regular primary education in Leiden, The Netherlands, were recruited. A coin toss determined which group is the experimental group; the other group is the control group. All children in the experimental group received sit-to-stand desks. They are invited and motivated to reduce sedentary time at school, however, it is their own choice to sit or stand. Children in the control group use regular desks. Otherwise, both groups receive regular treatment. Outcomes are assessed at baseline (T0) and at five follow-up sessions (T1-T5) alternately in winter and summer seasons over three academic years. Primary outcome measures are academic performance, and the proportion of sitting time at school, measured with a 3D accelerometer. Secondary outcome measures are a number of measures related to executive functioning (e.g., N-back task for working memory), health (e.g., height and weight for BMI), and wellbeing (e.g., KIDSCREEN-52 for Quality of Life). DISCUSSION: A Good Beginning is a two-and-a-half-year research program, which aims to provide a better understanding of the long-term effects of sit-to-stand desks on sedentary time at school and the relation between sitting time reduction and academic performance, executive functioning, health and wellbeing. The findings may serve as useful information for policy making and practical decision making for school and classroom environments. TRIAL REGISTRATION: The program of "A Good Beginning" is registered at the Netherlands Trial Register (NTR, https://www.trialregister.nl), number NL6166, registration date 24 November 2016.

Explaining experiences of community-dwelling older adults with a pro-active comprehensive geriatric assessment program - a thorough evaluation by interviews.

INTRODUCTION: Pro-active assessment programs are increasingly used to improve care for older adults. These programs include comprehensive geriatric tailored to individual patient preferences. Evidence for the effects of these programs on patient outcomes is nevertheless scarce or ambiguous. Explaining these dissatisfying results is difficult due to the multi-component nature of the programs. The objective of the current study was to explore and explain the experience of older adults participating in a pro-active assessment program, to help to clarify the effects. METHODS: Semi-structured in-depth interviews were held with 25 participants of a pro-active assessment program for frail community-dwelling adults aged 65+. This study was part of an evaluation study on the effects of the program. Transcripts were analysed with thematic analysis and cross-case analysis. RESULTS: The participants' mean age was 78.5 (SD 6.9) and 56% was female. The majority of the participants were satisfied with the program but based this on communication aspects, since only a few of them expressed real program benefits. Participant experiences could be clustered in six themes: (1) All participants expressed the need for a holistic view which was covered in the program, (2) the scope of the CGA was broader than expected or unclear, (3) the program delivered unexpected but valued help, (4) participants described a very low sense of ownership, (5) timing of the program implementation or the CGA was difficult and(6), participants and care workers had a different view on what to consider as a problem. These experiences could be explained by three program components: the degree of (the lack of) integration of the program within usual care, the pro-active screening method and the broader than expected, but appreciated multi-domain approach. CONCLUSION: Older adults' need for a holistic view is covered by this outpatient assessment program. However, their engagement and the correct timing of the program are hampered by the pro-active recruitment and the limited integration of the program within existing care. Furthermore, satisfaction seems an insufficient guiding factor when evaluating CGA programs for older adults because it does not reflect the impact of the program.

Temporal Dynamics of Health and Well-Being: A Crowdsourcing Approach to Momentary Assessments and Automated Generation of Personalized Feedback.

OBJECTIVE: Recent developments in research and mobile health enable a quantitative idiographic approach in health research. The present study investigates the potential of an electronic diary crowdsourcing study in the Netherlands for (1) large-scale automated self-assessment for individual-based health promotion and (2) enabling research at both the between-persons and within-persons level. To illustrate the latter, we examined between-persons and within-persons associations between somatic symptoms and quality of life. METHODS: A website provided the general Dutch population access to a 30-day (3 times a day) diary study assessing 43 items related to health and well-being, which gave participants personalized feedback. Associations between somatic symptoms and quality of life were examined with a linear mixed model. RESULTS: A total of 629 participants completed 28,430 assessments, with a mean (SD) of 45 (32) assessments per participant. Most participants (n = 517 [82%]) were women and 531 (84%) had high education. Almost 40% of the participants (n = 247) completed enough assessments (t = 68) to generate personalized feedback including temporal dynamics between well-being, health behavior, and emotions. Substantial between-person variability was found in the within-person association between somatic symptoms and quality of life. CONCLUSIONS: We successfully built an application for automated diary assessments and personalized feedback. The application was used by a sample of mainly highly educated women, which suggests that the potential of our intensive diary assessment method for large-scale health promotion is limited. However, a rich data set was collected that allows for group-level and idiographic analyses that can shed light on etiological processes and may contribute to the development of empirical-based health promotion solutions.

Assessment of Biopsychosocial Complexity and Health Care Needs: Measurement Properties of the INTERMED Self-Assessment Version.

OBJECTIVE: The INTERMED Self-Assessment questionnaire (IMSA) was developed as an alternative to the observer-rated INTERMED (IM) to assess biopsychosocial complexity and health care needs. We studied feasibility, reliability, and validity of the IMSA within a large and heterogeneous international sample of adult hospital inpatients and outpatients as well as its predictive value for health care use (HCU) and quality of life (QoL). METHODS: A total of 850 participants aged 17 to 90 years from five countries completed the IMSA and were evaluated with the IM. The following measurement properties were determined: feasibility by percentages of missing values; reliability by Cronbach α; interrater agreement by intraclass correlation coefficients; convergent validity of IMSA scores with mental health (Short Form 36 emotional well-being subscale and Hospital Anxiety and Depression Scale), medical health (Cumulative Illness Rating Scale) and QoL (Euroqol-5D) by Spearman rank correlations; and predictive validity of IMSA scores with HCU and QoL by (generalized) linear mixed models. RESULTS: Feasibility, face validity, and reliability (Cronbach α = 0.80) were satisfactory. Intraclass correlation coefficient between IMSA and IM total scores was .78 (95% CI = .75-.81). Correlations of the IMSA with the Short Form 36, Hospital Anxiety and Depression Scale, Cumulative Illness Rating Scale, and Euroqol-5D (convergent validity) were -.65, .15, .28, and -.59, respectively. The IMSA significantly predicted QoL and also HCU (emergency department visits, hospitalization, outpatient visits, and diagnostic examinations) after 3- and 6-month follow-up. Results were comparable between hospital sites, inpatients and outpatients, as well as age groups. CONCLUSIONS: The IMSA is a generic and time-efficient method to assess biopsychosocial complexity and to provide guidance for multidisciplinary care trajectories in adult patients, with good reliability and validity across different cultures.

Impact of physical and mental health on life satisfaction in old age: a population based observational study.

BACKGROUND: It is widely assumed that poor health lowers life satisfaction when ageing. Yet, research suggests this relationship is not straightforward. This study investigated how older people evaluate their life when facing disease and disabilities. METHODS: The Leiden 85-plus Study, a prospectively followed cohort of a cohort of a middle-sized city in the Netherlands, all aged 85 years, that was age-representative of the general population, was used. Those with severe cognitive dysfunction were excluded (n = 501). Comorbidities, physical performance, cognitive function, functional status, residual lifespan, depressive symptoms and experienced loneliness were measured during home visits. Life satisfaction was self-reported with Cantril's ladder. All analyses were performed using regression analysis. RESULTS: Participants reported high life satisfaction (median 8 out of 10 points) despite having representative levels of disease and disability. Comorbidity, low cognitive function, and residual lifespan as markers of health were not associated with life satisfaction. Poor physical performance and low functional status were weakly but significantly associated with lower life satisfaction (p < 0.05 respectively p < 0.001), but significance was lost after adjustment for depressive symptoms and perceived loneliness. Depressive symptoms and perceived loneliness were strongly related to lower life satisfaction (both p < 0.001), even after adjustment for physical health characteristics. CONCLUSION: Poor physical health was hardly related to lower life satisfaction, whereas poor mental health was strongly related to lower life satisfaction. This indicates that mental health has a greater impact on life satisfaction at old age than physical health, and that physical health is less relevant for a satisfactory old age.

Cardiovascular risk profile and cognitive function in young, middle-aged, and elderly subjects.

BACKGROUND AND PURPOSE: Cognitive decline occurs earlier than previously realized and is already evident at the age of 45. Because cardiovascular risk factors are established risk factors for cognitive decline in old age, we investigated whether cardiovascular risk factors are also associated with cognitive decline in young and middle-aged groups. METHODS: The cross-sectional study included 3778 participants aged 35 to 82 years (mean age, 54 years) and free of cardiovascular disease and stroke. Cognitive function was measured with the Ruff Figural Fluency Test (RFFT; worst score, 0; best score, 175 points) and the Visual Association Test (VAT; worst score, 0; best score, 12 points). Overall cardiovascular risk was assessed with the Framingham Risk Score (FRS) for general cardiovascular disease (best score, -5; worst score, 33 points). RESULTS: Mean RFFT score (SD) was 70 (26) points, median VAT score (interquartile range) was 10 (9-11) points, and mean FRS (SD) was 10 (6) points. Using linear regression analysis adjusting for educational level, RFFT was negatively associated with FRS. RFFT score decreased by 1.54 points (95% confidence interval, -1.66 to -1.44; P<0.001) per point increase in FRS. This negative association was not only limited to older age groups, but also found in the young (35-44 years). The main influencing components of the FRS were age (P<0.001), diabetes mellitus (P=0.001), and smoking (P<0.001). Similar results were found for VAT score as outcome measure. CONCLUSIONS: In this large population-based cohort, a worse overall cardiovascular risk profile was associated with poorer cognitive function. This association was already present in young adults aged 35 to 44 years.

Interprofessional education in primary care for the elderly: a pilot study.

BACKGROUND: The Dutch health care system faces huge challenges with regard to the demand on elderly care and the competencies of nurses and physicians required to meet this demand.At present, the main focus of health care in the Netherlands lies on illness and treatment. However, (frail) elderly need care and support that takes their daily functioning and well-being into consideration as well. Therefore, health care professionals, especially those professionals working in primary care such as GPs and practice nurses, will be challenged to a paradigm shift in emphasis from treating illness to promoting health (healthy ageing). Interprofessional education is necessary to realise this shift in professional behaviour. Evidence indicates that interprofessional education (IPE) can play a pivotal role in enhancing the competencies of professionals in order to provide elderly care that is both effectively, integrated and well-coordinated. At present, however, IPE in primary care is rarely utilised in the Netherlands. Therefore, the aim of this pilot study was to develop an IPE program for GPs and practice nurses and to evaluate the feasibility of an IPE program for professionals with different educational backgrounds and its effect on the division of professionals' tasks and responsibilities. METHODS: Ten GPs and 10 practice nurses from eight primary care practices in two provinces in the north of the Netherlands, Groningen and Drenthe (total population about 1.1 million people), participated in the pilot IPE program. A mixed methods design including quantitative and qualitative methods was used to evaluate the IPE program. RESULTS: During the program, tasks and responsibilities, in particular those related to the care plan, shifted from GP to practice nurse. The participants' attitude toward elderly (care) changed and the triage instrument, the practical tool for prioritising preferences of the elderly and discussing their medication use, was considered to have an added value to the development of the care plan. CONCLUSIONS: The results of this pilot study show that an interprofessional education program for professionals with different educational backgrounds (GPs and practice nurses) is feasible and has an added value to the redefining of tasks and responsibilities among GPs and practice nurses.

Effectiveness of a supervisor training on quality of feedback to internal medicine residents: a controlled longitudinal multicentre study.

OBJECTIVES: High-quality feedback on different dimensions of competence is important for resident learning. Supervisors may need additional training and information to fulfil this demanding task. This study aimed to evaluate whether a short and simple training improves the quality of feedback residents receive from their clinical supervisors in daily practice. DESIGN: Longitudinal quasi-experimental controlled study with a pretest/post-test design. We collected multiple premeasurements and postmeasurements for each supervisor over 2 years. A repeated measurements ANOVA was performed on the data. SETTING: Internal medicine departments of seven Dutch teaching hospitals. PARTICIPANTS: Internal medicine supervisors (n=181) and residents (n=192). INTERVENTION: Half of the supervisors attended a short 2.5-hour training session during which they could practise giving feedback in a simulated setting using video fragments. Highly experienced internal medicine educators guided the group discussions about the feedback. The other half of the supervisors formed the control group and received no feedback training. OUTCOME MEASURES: Residents rated the quality of supervisors' oral feedback with a previously validated questionnaire. Furthermore, the completeness of the supervisors' written feedback on evaluation forms was analysed. RESULTS: The data showed a significant increase in the quality of feedback after the training F (1, 87)=6.76, p=0.04. This effect remained significant up to 6 months after the training session. CONCLUSIONS: A short training session in which supervisors practise giving feedback in a simulated setting increases the quality of their feedback. This is a promising outcome since it is a feasible approach to faculty development.

Linking a peer coach physical activity intervention for older adults to a primary care referral scheme.

BACKGROUND: Physical inactivity has contributed to the current prevalence of many age-related diseases, including type 2 diabetes and cardiovascular disease. Peer coach physical activity intervention are effective in increasing long term physical activity in community dwelling older adults. Linking peer coach physical activity interventions to formal care could therefore be a promising novel method to improve health in inactive older adults to a successful long-term physical activity intervention. METHODS: We evaluated the effects of linking a peer coach physical activity intervention in Leiden, The Netherlands to primary care through an exercise referral scheme from July 2018 to April 2020. Primary care practices in the neighborhoods of three existing peer coach physical activity groups were invited to refer patients to the exercise groups. Referrals were registered at the primary care practice and participation in the peer coach groups was registered by the peer coaches of the exercise groups. RESULTS: During the study, a total of 106 patients were referred to the peer coach groups. 5.7% of patients participated at the peer coach groups and 66.7% remained participating during the 1 year follow up. The number needed to refer for 1 long term participant was 26.5. The mean frequency of participation of the referred participants was 1.2 times a week. CONCLUSION: Linking a peer coach physical activity intervention for older adults to a primary care referral scheme reached only a small fraction of the estimated target population. However, of the people that came to the peer coach intervention a large portion continued to participate during the entire study period. The number needed to refer to engage one older person in long term physical activity was similar to other referral schemes for lifestyle interventions. The potential benefits could be regarded proportional to the small effort needed to refer.

Structured analyses of interventions to prevent delirium.

BACKGROUND: Delirium is one of the most serious complications in hospitalized elderly, with incidences ranging from 3-56%. The objective of this meta-analysis was two-fold, first to investigate if interventions to prevent delirium are effective and second to explore which factors increase the effectiveness of these interventions. METHODS: An electronic search was carried out on articles published between January 1979 and July 2009. Abstracts were reviewed, data were extracted and methodologic quality was assessed by two independent reviewers. Effect sizes of the interventions were expressed as ORs (odds ratios) and 95%CIs (confidence intervals). A random effect model was used to provide pooled ORs. To explore which factors increase the effectiveness of the interventions, ORs were stratified for several factors. RESULTS: Sixteen relevant studies were found. Overall the included studies showed a positive result of any intervention to prevent delirium (pooled OR: 0.64; 95%CI: 0.46-0.88). The largest effect was seen in studies on populations with an incidence of delirium above 30% in the control group (pooled OR: 0.34; 95%CI: 0.16-0.71 versus 0.76; 95%CI: 0.60-0.97). CONCLUSIONS: Interventions to prevent delirium are effective. Interventions seem to be more effective when the incidence of delirium in the population under study is above 30%. To maximize the options for a cost-effective strategy of delirium prevention it might be useful to offer an intervention to a selected population.

Goal planning in person-centred care supports older adults receiving case management to attain their health-related goals.

PURPOSE: Care for older adults should preferably be provided in a person-centred way that includes goal planning. The aim of the present cohort study is to gain an insight into the results of goal planning, in a person-centred care setting for community-living older adults. MATERIALS AND METHODS: Within Embrace, a person-centred and integrated care service, older adults set goals with the aim to improve health-related problems. For every goal, they rated severity scores ranging from 0 (no problem) to 10 (extremely severe): a baseline score, a target score and, within one year, an end score to evaluate these goals. The differences between baseline and end scores (goal progress) and target and end scores (goal attainment), and the percentage of goals attained were calculated and compared between health-related domains (i.e., mental health, physical health, mobility, and support). RESULTS: Among 233 older adults, 836 goal plans were formulated of which 74% (95% Confidence Interval: 71-77) were attained. Goals related to physical health were the most likely to be attained and goals for mobility and pain the least likely. CONCLUSIONS: Older adults are able to attain health-related goals through collaborative goal planning. We recommend future integrated care programmes for older adults to incorporate goal-planning methods to achieve person-centred care.IMPLICATIONS FOR REHABILITATIONOlder adults experiencing frailty or complex care needs and receiving individual support within an integrated care setting are able to formulate and attain goals using goal planning with severity scores.Goal plans of community-living older adults mostly aim at improving health-related problems concerning physical health, mobility, or support.Goals related to physical health are the most likely to be attained, while goals for mobility and pain are the least likely to be attained.

Increasing Older Adult Involvement in Geriatric Assessment: A Mixed-Methods Process Evaluation.

Objectives: Goal setting and motivational interviewing (MI) may increase well-being by promoting healthy behavior. Since we failed to show improved well-being in a proactive assessment service for community-dwelling older adults applying these techniques, we studied whether implementation processes could explain this. Methods: Goals set during the comprehensive geriatric assessment were evaluated on their potential for behavior change. MI and goal setting adherence wasassessed by reviewing audiotaped interactions and interviewing care professionals. Results: Among the 280 goals set with 230 frail older adults (mean age 77 ± 6.9 years, 59% women), more than 90% had a low potential for behavior change. Quality thresholds for MI were reached in only one of the 11 interactions. Application was hindered by the context and the limited proficiency of care professionals. Discussion: Implementation was suboptimal for goal setting and MI. This decreased the potential for improved well-being in the participating older adults.

Predictors of incident major depression in diabetic outpatients with subthreshold depression.

AIMS: The objective of the study was to determine rates and risks of major depression in diabetes outpatients with subthreshold depression. METHODS: This study is based on data of a stepped care-based intervention study in which diabetic patients with subthreshold depression were randomly allocated to low-intensity stepped care, aimed at reducing depressive symptoms, or to care as usual. Patients had a baseline Center for Epidemiologic Studies Depression Scale (CES-D) score ≥ 16, but no baseline major depression according to the Mini International Neuropsychiatric Interview (MINI). Demographic, biological and psychological characteristics were collected at baseline. The MINI was used to determine whether participants had major depression during 2-year follow-up. Predictors of major depression were studied using logistic regression models. RESULTS: Of the 114 patients included at baseline, 73 patients were available at 2-year follow-up. The 2-year incidence of major depression was 42% (n=31). Higher baseline anxiety levels [odds ratio (OR)=1.25; 95% confidence interval (CI), 1.04-1.50; P=0.018] and depression severity levels (OR=1.09; 95% CI, 1.00-1.18; P=0.045) were predictors of incident major depression. Stepped care allocation was not related to incident major depression. In multivariable models, similar results were found. CONCLUSIONS: Having a higher baseline level of anxiety and depression appeared to be related to incident major depression during 2-year follow-up in diabetic patients with subthreshold depression. A stepped care intervention aimed at depression alone did not prevent the onset of depression in these patients. Besides level of depression, anxiety might be taken into account in the prevention of major depression in diabetic patients with subthreshold depression.

Age-specific associations between cardiac vagal activity and functional somatic symptoms: a population-based study.

BACKGROUND: Functional somatic symptoms (FSS) are symptoms not explained by underlying organic pathology. It has frequently been suggested that dysfunction of the autonomic nervous system (ANS) contributes to the development of FSS. We hypothesized that decreased cardiac vagal activity is cross-sectionally and prospectively associated with the number of FSS in the general population. METHODS: This study was performed in a population-based cohort of 774 adults (45.1% male, mean age +/- SD 53.5 +/- 10.7 years). Participants completed the somatization section of the Composite International Diagnostic Interview surveying the presence of 43 FSS. ANS function was assessed by spectral analysis of heart rate variability in the high-frequency band (HRV-HF), reflecting cardiac vagal activity. Follow-up measurements of HRV-HF and FSS were performed approximately 2 years later. RESULTS: Linear regression analyses, with adjustments for gender, age, body mass index, anxiety, depression, smoking, alcohol use, and frequency of exercise, revealed an interaction of cardiac vagal activity with age: HRV-HF was negatively associated with FSS in adults 52 years (beta = 0.13, t = 2.51, p = 0.012). Longitudinal analysis demonstrated a similar pattern. CONCLUSIONS: Decreased cardiac vagal activity is associated with a higher number of FSS in adults aged 52 years needs further exploration. The role of age should be acknowledged in future studies on ANS function in the etiology of FSS.

Prevalence of frailty on clinical wards: description and implications.

This paper describes the prevalence and frailty level of patients aged > or = 75 years upon admission to various clinical wards. The data collection took place on five clinical wards of different clinical specialisms: Geriatric Centre, traumatology, pulmonology/rheumatology, internal medicine and surgical medicine. The Groningen Frailty Indicator was used to assess the frailty of newly admitted patients. The presence of number and kind of the various frailty indicators was different for the clinical wards, because of clinical diagnose, age and gender. On the Geriatric Centre, almost all patients were indicated as frail. On the other wards, 50-80% of the patients were indicated as frail with most frailty indicators on the scale 'psychosocial'. The study show a high prevalence of frail elderly on some wards and gives an indication of the various needs for other disciplines within the framework of the care for frail elderly people.

Self-organizing peer coach groups to increase daily physical activity in community dwelling older adults.

Many older adults do not reach the recommended level of physical activity, despite many professional-delivered physical activity interventions. Here we study the implementation of a novel physical activity intervention for older adults that is self-sustainable (no financial support) and self-organizing (participants act as organizers) due to peer coaching. We implemented three groups and evaluated process and effect using participatory observations, questionnaires, six-minute walk tests and body composition measures from October 2016 to September 2018. The intervention was implemented by staff without experience in physical activity interventions. Facilitators were a motivated initiator and a non-professional atmosphere for participants to take ownership. Barriers were the absence of motivated participants to take ownership and insufficient participants to ensure the presence of participants at every exercise session. The groups exercised outside five days a week and were self-organizing after 114, 216 and 263 days. The initial investments were 170€ for sport equipment and 81-187 h. The groups reached 118 members and a retention of 86.4% in two years. The groups continue to exist at the time of writing and are self-sustainable. Quality of life increased 0.4 on a ten-point scale (95%CI 0.1-0.7; p = 0.02) and six-minute walk test results improved with 33 m (95%CI 18-48; p < 0.01) annually. Self-organizing peer coach groups for physical activity are feasible, have positive effects on health and require only a small investment at the start. It is a sustainable and potentially scalable intervention that could be a promising method to help many older adults age healthier.

Impact of a Nurse-Led Health Promotion Intervention in an Aging Population: Results From a Quasi-Experimental Study on the "Community Health Consultation Offices for Seniors".

Objective: The study evaluated the nurse-led intervention "Community Health Consultation Offices for Seniors (CHCO)" on health-related and care needs-related outcomes in community-dwelling older people (⩾60 years). Method: With a quasi-experimental design, the CHCO intervention was evaluated on health-related and care needs-related outcomes after 1-year follow-up. Older people who received the intervention were frail, overweight, or were smoking. The comparison group received care as usual. In both groups, similar data were collected on health status, falls and fractures, and care needs. In the intervention group, additional data were collected on biometric measures and health-related behavior. Results: The intervention group and the care-as-usual group included 403 seniors and 984 seniors, respectively. Health-related outcomes, behaviors, and biometric measures, remained stable. After 1 year, care needs increased for both groups, but at a lower rate for the care-as-usual group. Discussion: The CHCO intervention showed no significant improvement on health-related outcomes or stability in care needs-related outcomes.

Is high-sensitive C-reactive protein a biomarker for functional somatic symptoms? A population-based study.

Functional somatic symptoms (FSS) are symptoms unexplained in terms of underlying organic pathology. Alterations in the immune system function may be associated with FSS via induction of sickness behavior. We aimed to investigate whether low-grade immune system activation is positively associated with FSS in a population-based cohort of 881 adults (46% male, mean age 53.0, SD 11.4). Participants completed the somatization section of the Composite International Diagnostic Interview surveying the presence of 43 FSS. Innate immune function was assessed by measuring high-sensitive C-reactive protein (hs-CRP). Follow-up measurements of hs-CRP and FSS were performed approximately 2years later. Regression analyses, with adjustments for gender, age, body mass index, anxiety, depression, smoking, alcohol use, and frequency of exercise, did not reveal a cross-sectional association (beta=0.01, t=0.40, p=0.693) or longitudinal association (beta=-0.03, t=-0.93, p=0.352) between hs-CRP and the total number of FSS. When examining different bodily clusters of FSS, hs-CRP was not associated with the gastrointestinal FSS cluster, but the association approached statistical significance for the general FSS cluster (OR 1.08, 95% CI 0.98-1.18) and musculoskeletal FSS cluster (OR 1.08, 95% CI 0.99-1.17). For the latter association, exploratory analyses revealed that mainly the pure musculoskeletal complaints were responsible (OR 1.12, 95% CI 1.03-1.21). We conclude that the level of hs-CRP is not a biomarker for the total number of FSS in the general population. The association between hs-CRP and musculoskeletal and general FSS needs further study.
