Older adults increasingly combine employment with informal care and/or voluntary work. This is good for society but raises the question whether combining multiple roles is also good for individual well-being. Based on data from the Longitudinal Aging Study Amsterdam (N = 1885), associations between role combinations, role intensity (in employment, informal care and volunteering) and well-being are examined using role enhancement and role strain perspectives. We investigate if social network and mastery (the feeling of control over his or her life) buffer potential negative effects of role combinations and role intensity on well-being. Intensive informal care is related with more depressive symptoms, which is fully mediated by mastery. Fulltime employment is related with lower levels of depressive symptoms, and this is fully mediated by mastery. Social network size does not mediate any relationship between role combinations or role intensities and depressive symptoms. Both parttime and fulltime employment are negatively related to depressive symptoms. The study suggests that combining roles is positively related to well-being when role strain is low. Interventions should be directed at maintaining mastery among those providing intensive informal care, in particular when combined with employment and/or volunteering.

Background: Gestational diabetes mellitus (GDM) is associated with perinatal health risks to both mother and offspring, and represents a large economic burden. The DALI study is a multicenter randomized controlled trial, undertaken to add to the knowledge base on the effectiveness of interventions for pregnant women at increased risk for GDM. The purpose of this study was to evaluate the cost-effectiveness of the healthy eating and/or physical activity promotion intervention compared to usual care among pregnant women at increased risk of GDM from a societal perspective.Methods: An economic evaluation was performed alongside a European multicenter-randomized controlled trial. A total of 435 pregnant women at increased risk of GDM in primary and secondary care settings in nine European countries, were recruited and randomly allocated to a healthy eating and physical activity promotion intervention (HE + PA intervention), a healthy eating promotion intervention (HE intervention), or a physical activity promotion intervention (PA intervention). Main outcome measures were gestational weight gain, fasting glucose, insulin resistance (HOMA-IR), quality adjusted life years (QALYs), and societal costs.Results: Between-group total cost and effect differences were not significant, besides significantly less gestational weight gain in the HE + PA group compared with the usual care group at 35–37 weeks (−2.3;95%CI:-3.7;-0.9). Cost-effectiveness acceptability curves indicated that the HE + PA intervention was the preferred intervention strategy. At 35–37 weeks, it depends on the decision-makers' willingness to pay per kilogram reduction in gestational weight gain whether the HE + PA intervention is cost-effective for gestational weight gain, whereas it was not cost-effective for fasting glucose and HOMA-IR. After delivery, the HE + PA intervention was cost-effective for QALYs, which was predominantly caused by a large reduction in delivery-related costs.Conclusions: Healthy eating and physical activity promotion was found to be the preferred strategy for limiting gestational weight gain. As this intervention was cost-effective for QALYs after delivery, this study lends support for broad implementation.Trial registration: ISRCTN ISRCTN70595832. Registered 2 December 2011.

BACKGROUND: Frailty is a state of increased vulnerability to adverse outcomes. The frailty index (FI), defined by the deficit accumulation approach, is a sensitive instrument to measure levels of frailty, and therefore important for longitudinal studies of aging.AIMS: To develop an FI in the Longitudinal Aging Study Amsterdam (LASA), and to examine the predictive validity of this FI for 19-year mortality.METHODS: LASA is an ongoing study among Dutch older adults, based on a nationally representative sample. A 32-item FI (LASA-FI) was developed at the second LASA measurement wave (1995-1996) among 2218 people aged 57-88 years. An FI score between 0 and 1 was calculated for each individual. The LASA-FI included health deficits from the physical, mental and cognitive domain and can be constructed for most LASA measurement waves. Associations with 19-year mortality were assessed using Kaplan-Meier curves and Cox proportional hazards models.RESULTS: The mean LASA-FI score was 0.19 (SD = 0.12), with a 99% upper limit of 0.53. Scores were higher in women than men (women = 0.20, SD = 0.13 vs. men = 0.17, SD = 0.11, p < 0.001). The average age-related increase in the log-transformed LASA-FI score was 3.5% per year. In a model adjusted for age and sex, the FI score was significantly associated with 19-year all-cause mortality (HR per 0.01 = 1.03, 95% CI 1.03-1.04, p < 0.001).DISCUSSION/CONCLUSIONS: The key characteristics of the LASA-FI were in line with findings from previous FI studies in population-based samples of older people. The LASA-FI score was associated with mortality and may serve as an internal and external reference value.

Background: Process evaluation is an essential part of designing and assessing complex interventions. The vitamin D and lifestyle intervention study (DALI) study is testing different strategies to prevent development of gestational diabetes mellitus among European obese pregnant women with a body mass index ≥29 kg/m2. The intervention includes guidance on physical activity and/or healthy eating by a lifestyle coach trained in motivational interviewing (MI). The aim of this study was to assess the process elements: reach, dose delivered, fidelity and satisfaction and to investigate whether these process elements were associated with changes in gestational weight gain (GWG).Methods: Data on reach, dose delivered, fidelity, and satisfaction among 144 participants were collected. Weekly recruitment reports, notes from meetings, coach logs and evaluation questionnaires (n = 110) were consulted. Fidelity of eight (out of twelve) lifestyle coach practitioners was assessed by analysing audio recorded counselling sessions using the MI treatment integrity scale. Furthermore, associations between process elements and GWG were assessed with linear regression analyses.Results: A total of 20% of the possible study population (reach) was included in this analysis. On average 4.0 (of the intended 5) face-to-face sessions were delivered. Mean MI fidelity almost reached 'expert opinion' threshold for the global scores, but was below 'beginning proficiency' for the behavioural counts. High variability in quality of MI between practitioners was identified. Participants were highly satisfied with the intervention, the lifestyle coach and the intervention materials. No significant associations were found between process elements and GWG.Conclusion: Overall, the intervention was well delivered and received by the study population, but did not comply with all the principles of MI. Ensuring audio recording of lifestyle sessions throughout the study would facilitate provision of individualized feedback to improve MI skills. A larger sample size is needed to confirm the lack of association between process elements and GWG.Trial registration: ISRCTN registry: ISRCTN70595832; Registered 12 December 2011.

Objective The objective of the current study was to explore whether time spent visiting green space near home acts as a mediator in the association between level of residential greenness and perceived mental health. Methods Questionnaire data and satellite data of residential greenness were gathered in four European cities (total n = 3748): Barcelona (SP), Doetinchem (NL), Kaunas (LT) and Stoke-on-Trent (UK). Results Mediation analyses showed that time spent visiting green space near home was a weak, but statistically significant, mediator in the pooled data and in the Dutch sample only. Conclusions The findings provide little support for the hypothesis that purposeful visits are a mediator linking indirectly greenness with mental health. More research is needed to explore other mediators related to different exposure pathways, such as visual exposure, and alternative mechanisms, such as (perceived) safety.

OBJECTIVE: To assess the effectiveness of individualized physiotherapy in combination with rigid taping compared with individualized physiotherapy alone in patients with subacromial pain syndrome.DESIGN: A prospective randomized trial with concealed allocation.PATIENTS: A total of 140 patients between 18 and 65 years of age from primary physiotherapy settings.METHODS: The intervention group received individualized physiotherapy and shoulder taping. The control group received individualized physiotherapy only. Primary outcomes were: pain intensit (numerical rating scale) and functioning (Simple Shoulder Test). Secondary outcomes were: global perceived effect and patient-specific complaints. Data were collected at baseline, and at 4, 12 and 26 weeks' follow-up.RESULTS: During the 6-month follow-up period multilevel analysis showed a significant difference between groups favouring the control group on pain intensity (p = 0.02), but not on functioning. Regarding secondary outcomes, a significant difference between groups was found favouring the intervention group for global perceived effect (p = 0.02), but not for patient-specific complaints.CONCLUSION: Rigid shoulder taping, as used in this study, cannot be recommended for improving physiotherapy outcomes in people with subacromial pain syndrome.

Background and Objective Randomized trials may be designed to provide evidence more strongly related to efficacy or effectiveness of an intervention. When systematic reviews are used to inform clinical or policy decisions, it is important to know the efficacy–effectiveness nature of the included trials. The objective of this study was to develop a tool to characterize randomized trials included in a systematic review on an efficacy–effectiveness continuum. Methods We extracted rating domains and descriptors from existing tools and used a modified Delphi procedure to condense the domains and develop a new tool. The feasibility and interrater reliability of the tool was tested on trials from four systematic reviews. Results The Rating of Included Trials on the Efficacy–Effectiveness Spectrum (RITES) tool rates clinical trials on a five-point Likert scale in four domains: (1) participant characteristics, (2) trial setting, (3) flexibility of interventions, and (4) clinical relevance of interventions. When RITES was piloted on trials from three reviews by unaffiliated raters, ratings were variable (intraclass correlation coefficient [ICC] 0.25–0.66 for the four domains); but, when RITES was used on one review by the review authors with expertise on the topic, the ratings were consistent (ICCs > 0.80. Conclusion RITES may help to characterize the efficacy–effectiveness nature of trials included in systematic reviews.

OBJECTIVES: To examine the effects of decreasing hospital length of stay (HLOS) on change in functioning from prehospital admission to posthospital discharge in older cohorts.DESIGN: Cohort-sequential design.SETTING: Nationwide, older population-based Longitudinal Aging Study Amsterdam (LASA).PARTICIPANTS: Individuals aged 68 and older with any hospital admission according to national medical registry data: two 10-year age groups (68-77 (younger-old) and 78-87 (older-old)) in two periods (1996-99 (Period 1) and 2006-09 (Period 2)) (N = 1,212).MEASUREMENTS: HLOS was the main independent variable in multinomial logistic models, dichotomized as 1 to 5 days (short) and 6 days or longer (long). Outcomes were change scores in mobility and activities in daily living (ADLs). Respondents who died during the 3-year period were assigned to a third outcome category.RESULTS: Results for both age groups showed more hospital admissions and shorter median HLOS in Period 2 than Period 1 (P < .05). Lower odds of decline in physical functioning were found in respondents with short HLOS than in those with long HLOS (for mobility: odds ratio (OR) = 0.36, 95% confidence interval (CI) = 0.23-0.54 (younger-old) and OR = 0.47, 95% CI = 0.30-0.72 (older-old); for ADLs: OR = 0.30, 95% CI = 0.19-0.48 (younger-old) and OR = 0.30, 95% CI = 0.18-0.53 (older-old)). Adjusting for confounders did not significantly change these estimates. Period did not modify these associations.CONCLUSION: Because the associations of HLOS with change in mobility and ADLs were the same in both periods, hospitalized older adults had neither advantage nor disadvantage from the decrease in HLOS. In addition, in both age groups, a greater percentage experienced the better functional outcomes and lower mortality associated with short admissions, which suggests an advantage of the decrease in HLOS.

This individual patient data meta-analysis aimed to evaluate the effects of exercise on quality of life (QoL) and physical function (PF) in patients with cancer, and to identify moderator effects of demographic (age, sex, marital status, education), clinical (body mass index, cancer type, presence of metastasis), intervention-related (intervention timing, delivery mode and duration, and type of control group), and exercise-related (exercise frequency, intensity, type, time) characteristics. Relevant published and unpublished studies were identified in September 2012 via PubMed, EMBASE, PsycINFO, and CINAHL, reference checking and personal communications. Principle investigators of all 69 eligible trials were requested to share IPD from their study. IPD from 34 randomised controlled trials (n = 4519 patients) that evaluated the effects of exercise compared to a usual care, wait-list or attention control group on QoL and PF in adult patients with cancer were retrieved and pooled. Linear mixed-effect models were used to evaluate the effects of the exercise on post-intervention outcome values (z-score) adjusting for baseline values. Moderator effects were studies by testing interactions. Exercise significantly improved QoL (β = 0.15, 95%CI = 0.10;0.20) and PF (β = 0.18, 95%CI = 0.13;0.23). The effects were not moderated by demographic, clinical or exercise characteristics. Effects on QoL (βdifference_in_effect = 0.13, 95%CI = 0.03;0.22) and PF (βdifference_in_effect = 0.10, 95%CI = 0.01;0.20) were significantly larger for supervised than unsupervised interventions. In conclusion, exercise, and particularly supervised exercise, effectively improves QoL and PF in patients with cancer with different demographic and clinical characteristics during and following treatment. Although effect sizes are small, there is consistent empirical evidence to support implementation of exercise as part of cancer care.

Background\ud Urban residents may experience cognitive fatigue and little opportunity for mental restoration due to a lack of access to nature. Natural outdoor environments (NOE) are thought to be beneficial for cognitive functioning, but underlying mechanisms are not clear.\ud \ud Objectives\ud To investigate the long-term association between NOE and cognitive function, and its potential mediators.\ud \ud Methods\ud This cross-sectional study was based on adult participants of the Positive Health Effects of the Natural Outdoor Environment in Typical Populations in Different Regions in Europe (PHENOTYPE) project. Data were collected in Barcelona, Spain; Doetinchem, the Netherlands; and Stoke-on-Trent, United Kingdom. We assessed residential distance to NOE, residential surrounding greenness, perceived amount of neighborhood NOE, and engagement with NOE. Cognitive function was assessed with the Color Trails Test (CTT). Mediation analysis was undertaken following Baron and Kenny.\ud \ud Results\ud Each 100 m increase in residential distance to NOE was associated with a longer CTT completion time of 1.50% (95% CI 0.13, 2.89). No associations were found for other NOE indicators and cognitive function. Neighborhood social cohesion was (marginally) significantly associated with both residential distance to NOE and CTT completion time, but no evidence for mediation was found. Nor were there indications for mediation by physical activity, social interaction with neighbors, loneliness, mental health, air pollution worries, or noise annoyance.\ud \ud Conclusions\ud Our findings provide some indication that proximity to nature may benefit cognitive function. We could not establish which mechanisms may explain this relationship.

Background Home-based care networks differ in size and composition, but little is known about the characteristics of care networks for those nearing the end of their lives. This study aimed to identify different types of home-based care networks of community-dwelling older adults in the Netherlands and to assess the association between care network type and the health status and socio-demographic characteristics of care recipients. Methods/design We used data from participants of the Longitudinal Aging Study Amsterdam (2001–2013) with chronic diseases or functional limitations who died within 12 months of their last interview and received home based personal and/or household care (n = 146). Latent Class Analysis was used to model distinct end-of-life care networks among this pooled cross-section of older people whose characteristics imply care needs. The Akaike information criterion was used to determine the optimal model. Associations between network type and care recipient characteristics were explored using conditional inference trees. Results We identified four types of care networks; a partner network (19%) in which care was mainly provided by partners, with little care from private caregivers or professionals, a mixed network (25%) in which care was provided by a combination of children, professionals and/or other family members, a private network (15%) in which only privately paid care was provided, and a professional network (40%) in which care was mainly provided by publicly paid professionals, sometimes with additional care from family or privately paid caregivers. Care networks near the end of life showed similar characteristics to those identified for older people more generally, but care seemed to be more intensive in the last year of life compared to the years preceding it. End-of-life care networks were mostly related to age, educational level and partner status. Formal care substitutes informal care whenever there is no partner or child present and able to provide care. Conclusion Our findings indicate that personal and household care can be quite intensive in the last year of life, especially for partner caregivers. To prevent caregiver burden, it is important that professionals make sure partner caregivers receive adequate and timely support to cope with the care situation.

Objectives Preterm birth is the leading pregnancy outcome associated with perinatal morbidity and mortality and remains difficult to prevent. There is evidence that some modifiable maternal health characteristics may influence the risk of preterm birth. Our aim was to investigate the relationships of self-reported maternal health behaviour and psychological characteristics in nulliparous women with spontaneous preterm birth in prenatal primary care. Methods The data of our prospective study was obtained from the nationwide DELIVER multicentre cohort study (September 2009–March 2011), which was designed to examine perinatal primary care in the Netherlands. In our study, consisting of 2768 nulliparous women, we estimated the relationships of various self-reported health behaviours (smoking, alcohol consumption, folic acid supplementation, daily fruit, daily fresh vegetables, daily hot meal and daily breakfast consumption) and psychological characteristics (anxious/depressed mood and health control beliefs) with spontaneous preterm birth as a dichotomous outcome. Due to the clustering of clients within midwife practices, Generalized Estimating Equations was used for these analyses. Results Low health control beliefs was the sole characteristic significantly associated with spontaneous preterm birth (odds ratio 2.26; 95 % confidence interval 1.51, 3.39) after being adjusted for socio-demographics, anthropometrics and the remaining health behaviour and psychological characteristics. The other characteristics were not significantly associated with spontaneous preterm birth. Conclusions for Practice Maternal low health control beliefs need to be explored further as a possible marker for women at risk for preterm birth, and as a potentially modifiable characteristic to be used in interventions which are designed to reduce the risk of spontaneous preterm birth.

Purpose The study aims to describe mechanisms that contribute to the tendency towards continuing chemotherapy in patients with advanced cancer. Methods The study conducted qualitative observations of outpatient clinic visits of 28 patients with advanced cancer (glioblastoma and metastatic colorectal cancer). Results We uncovered four mechanisms in daily oncology practice that can contribute to the tendency towards continuing chemotherapy in patients with advanced cancer: (1) “presenting the full therapy sets the standard”—patients seemed to base their justification for continuing chemotherapy on the “standard” therapy with the maximum number of cycles as presented by the physician at the start of the treatment; (2) “focus on standard evaluation moments hampers evaluation of care goals”—whether or not to continue the treatment was mostly only considered at standard evaluation moments; (3) “opening question guides towards focus on symptoms”—most patients gave an update of their physical symptoms in answer to the opening question of “How are you doing?” Physicians consequently discussed how to deal with this at length, which often took up most of the visit; (4) “treatment is perceived as the only option”—patients mostly wanted to continue with chemotherapy because they felt that they had to try every available option the physician offered. Physicians also often seemed to focus on treatment as the only option. Conclusion Discussing care goals more regularly with the patient, facilitated for instance by implementing early palliative care, might help counter the mechanisms and enable a more well-considered decision. This could be either stopping or continuing chemotherapy.

OBJECTIVE: To investigate patterns of physical activity in older adults with knee osteoarthritis (OA) compared to older adults without knee OA across 6 European countries. We expect country-specific differences in the physical activity levels between persons with knee OA compared to persons without knee OA. A varying degree of physical activity levels across countries would express a facilitating or impeding influence of the social, environmental, and other contextual factors on a physically active lifestyle.METHODS: Baseline cross-sectional data from the European Project on Osteoarthritis were analyzed. In total, 2,551 participants from 6 European countries (Germany, Italy, The Netherlands, Spain, Sweden, and the UK) were included.RESULTS: Participants with knee OA were less likely to follow physical activity recommendations and had poorer overall physical activity profiles than those without knee OA (mean 62.9 versus 81.5 minutes/day, respectively; P = 0.015). The magnitude of this difference varied across countries. Detailed analysis showed that low physical activity levels in persons with knee OA could be attributed to less everyday walking time (odds ratio 1.31, 95% confidence interval 1.07-1.62).CONCLUSION: This study highlighted the fact that having knee OA is associated with a varying degree of physical activity patterns in different countries. This national variation implies that low levels of physical activity among persons with knee OA cannot be explained exclusively by individual or disease-specific factors, but that social, environmental, and other contextual factors should also be taken into account.

Background: DNA methylation arrays are widely used in epigenome-wide association studies and methylation quantitative trait locus (mQTL) studies. Here, we performed the first genome-wide analysis of monozygotic (MZ) twin correlations and mQTLs on data obtained with the Illumina MethylationEPIC BeadChip (EPIC array) and compared the performance of the EPIC array to the Illumina HumanMethylation450 BeadChip (HM450 array) for buccal-derived DNA.Results: Good-quality EPIC data were obtained for 102 buccal-derived DNA samples from 49 MZ twin pairs (mean age = 7.5 years, range = 1–10). Differences between MZ twins in the cellular content of buccal swabs were a major driver for differences in their DNA methylation profiles, highlighting the importance to adjust for cellular composition in DNA methylation studies of buccal-derived DNA. After adjusting for cellular composition, the genome-wide mean correlation (r) between MZ twins was 0.21 for the EPIC array, and cis mQTL analysis in 84 twins identified 1,296,323 significant associations (FDR 5%), encompassing 33,749 methylation sites and 616,029 genetic variants. MZ twin correlations were slightly larger (p −16) for novel EPIC probes (N = 383,066, mean r = 0.22) compared to probes that are also present on HM450 (N = 406,822, mean r = 0.20). In line with this observation, a larger percentage of novel EPIC probes was associated with genetic variants (novel EPIC probes with significant mQTL 4.7%, HM450 probes with mQTL 3.9%, p −16). Methylation sites with a large MZ correlation and sites associated with mQTLs were most strongly enriched in epithelial cell DNase I hypersensitive sites (DHSs), enhancers, and histone mark H3K4me3.Conclusions: We conclude that the contribution of familial factors to individual differences in DNA methylation and the effect of mQTLs are larger for novel EPIC probes, especially those within regulatory elements connected to active regions specific to the investigated tissue.

Purpose: This study aimed to evaluate the long-term effectiveness and cost-effectiveness of high intensity (HI) versus low-to-moderate intensity (LMI) exercise on physical fitness, fatigue, and health-related quality of life (HRQoL) in cancer survivors. Methods: Two hundred seventy-seven cancer survivors participated in the Resistance and Endurance exercise After ChemoTherapy (REACT) study and were randomized to 12 weeks of HI (n = 139) or LMI exercise (n = 138) that had similar exercise types, durations, and frequencies, but different intensities. Measurements were performed at baseline (4–6 weeks after primary treatment), and 12 (i.e., short term) and 64 (i.e., longer term) weeks later. Outcomes included cardiorespiratory fitness, muscle strength, self-reported fatigue, HRQoL, quality-adjusted life years (QALYs) and societal costs. Linear mixed models were conducted to study (a) differences in effects between HI and LMI exercise at longer term, (b) within-group changes from short term to longer term, and (c) the cost-effectiveness from a societal perspective. Results: At longer term, intervention effects on role (β = 5.9, 95% CI = 0.5; 11.3) and social functioning (β = 5.7, 95%CI = 1.7; 9.6) were larger for HI compared to those for LMI exercise. No significant between-group differences were found for physical fitness and fatigue. Intervention-induced improvements in cardiorespiratory fitness and HRQoL were maintained between weeks 12 and 64, but not for fatigue. From a societal perspective, the probability that HI was cost-effective compared to LMI exercise was 0.91 at 20,000€/QALY and 0.95 at 52,000€/QALY gained, mostly due to significant lower healthcare costs in HI exrcise. Conclusions: At longer term, we found larger intervention effects on role and social functioning for HI than for LMI exercise. Furthermore, HI exercise was cost-effective with regard to QALYs compared to LMI exercise. Trial registration: This study is registered at the Netherlands Trial Register [NTR2153 [http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=2153]] on the 5th of January 2010. Implications for Cancer Survivors: Exercise is recommended to be part of standard cancer care, and HI may be preferred over LMI exercise.

Obese individuals are characterized by altered brain reward responses to food. Despite the latest discovery of obesity-associated genes, the contribution of environmental and genetic factors to brain reward responsiveness to food remains largely unclear. Sixteen female monozygotic twin pairs with a mean BMI discordance of 3.96 ± 2.1 kg/m2 were selected from the Netherlands Twin Register to undergo functional MRI scanning while watching high- and low-calorie food and non-food pictures and during the anticipation and receipt of chocolate milk. In addition, appetite ratings, eating behavior and food intake were assessed using visual analog scales, validated questionnaires and an ad libitum lunch. In the overall group, visual and taste stimuli elicited significant activation in regions of interest (ROIs) implicated in reward, i.e. amygdala, insula, striatum and orbitofrontal cortex. However, when comparing leaner and heavier co-twins no statistically significant differences in ROI-activations were observed after family wise error correction. Heavier versus leaner co-twins reported higher feelings of hunger (P = 0.02), cravings for sweet food (P = 0.04), body dissatisfaction (P < 0.05) and a trend towards more emotional eating (P = 0.1), whereas caloric intake was not significantly different between groups (P = 0.3). Our results suggest that inherited rather than environmental factors are largely responsible for the obesity-related altered brain responsiveness to food. Future studies should elucidate the genetic variants underlying the susceptibility to reward dysfunction and obesity. Clinical Trial Registration Number: NCT02025595.

Background:In the MEETINGDEM project, the Meeting Centers Support Program (MCSP) was adaptively implemented and evaluated in three European countries: Italy, Poland, and the United Kingdom. The aim of this study was to investigate overall and country-specific facilitators and barriers to the implementation of MCSP in these European countries.Methods:A qualitative multiple case study design was used. Based on the theoretical model of adaptive implementation, a checklist was composed of potential facilitators and barriers to the implementation of MCSP. This checklist was administered among stakeholders involved in the implementation of MCSP to trace the experienced facilitators and barriers. Twenty-eight checklists were completed.Results:Main similarities between countries were related to the presence of suitable staff, management, and a project manager, and the fact that the MCSP is attuned to needs and wishes of people with dementia and informal caregivers. Main differences between countries were related to: communication with potential referrers, setting up an inter-organizational collaboration network, receiving support of national organizations, having clear discharge criteria for the MCSP and continuous PR in the region.Conclusion:The results of this study provide insight into generic and country specific factors that can influence the implementation of MCSP in different European countries. This study informs further implementation and dissemination of MCSP in Europe and may also serve as an example for the dissemination and implementation of other effective psychosocial support interventions for people with dementia and their informal caregivers across and beyond Europe.

ObjectiveLoneliness and depression have a strong reciprocal influence, and both predict adverse health outcomes at old age. Therefore, this study examines whether loneliness is associated with the presence of cardiovascular diseases taking into account the role of late-life depression. MethodsCross-sectional data of 477 older adults in the Netherlands Study of Depressed Older Persons were used. Logistic regression analysis was performed to examine the relation between loneliness and cardiovascular disease. Depression was added to the regression model to examine whether depression is an explanatory factor in the association between loneliness and cardiovascular disease. Interaction terms between loneliness and depression and between loneliness and sex were introduced in the regression model to investigate whether depressed and non-depressed participants, and men and women differed in their association between loneliness and cardiovascular disease. ResultsOf the overall group, 61% were lonely, 28% had a history of cardiovascular disease and 74% were depressed. Loneliness and cardiovascular disease were not associated in the overall group after adjustment for confounders (continuous: odds ratio [OR]=1.04, 95% confidence interval [CI]=0.98-1.10), p=0.25; dichotomous: OR=1.27, 95% CI=0.80-2.03, p=0.32). For women, there was an association between loneliness and cardiovascular diseases (continuous: OR=1.13, 95% CI=1.06-1.21, p

Glucagon-like peptide 1 (GLP-1) stimulated insulin secretion has a considerable heritable component as estimated from twin studies, yet few genetic variants influencing this phenotype have been identified. We performed the first genome-wide association study (GWAS) of GLP-1 stimulated insulin secretion in non-diabetic individuals from the Netherlands Twin register (n = 126). This GWAS was enhanced using a tissue-specific protein-protein interaction network approach. We identified a beta-cell protein-protein interaction module that was significantly enriched for low gene scores based on the GWAS P-values and found support at the network level in an independent cohort from Tübingen, Germany (n = 100). Additionally, a polygenic risk score based on SNPs prioritized from the network was associated (P < 0.05) with glucose-stimulated insulin secretion phenotypes in up to 5,318 individuals in MAGIC cohorts. The network contains both known and novel genes in the context of insulin secretion and is enriched for members of the focal adhesion, extracellular-matrix receptor interaction, actin cytoskeleton regulation, Rap1 and PI3K-Akt signaling pathways. Adipose tissue is, like the beta-cell, one of the target tissues of GLP-1 and we thus hypothesized that similar networks might be functional in both tissues. In order to verify peripheral effects of GLP-1 stimulation, we compared the transcriptome profiling of ob/ob mice treated with liraglutide, a clinically used GLP-1 receptor agonist, versus baseline controls. Some of the upstream regulators of differentially expressed genes in the white adipose tissue of ob/ob mice were also detected in the human beta-cell network of genes associated with GLP-1 stimulated insulin secretion. The findings provide biological insight into the mechanisms through which the effects of GLP-1 may be modulated and highlight a potential role of the beta-cell expressed genes RYR2, GDI2, KIAA0232, COL4A1 and COL4A2 in GLP-1 stimulated insulin secretion.

Contains fulltext : 184154.pdf (Publisher’s version ) (Open Access) Coronary microvascular resistance is increasingly measured as a predictor of clinical outcomes, but there is no accepted gold-standard measurement. We compared the diagnostic accuracy of 2 invasive indices of microvascular resistance, Doppler-derived hyperemic microvascular resistance (hMR) and thermodilution-derived index of microcirculatory resistance (IMR), at predicting microvascular dysfunction. A total of 54 patients (61 +/- 10 years) who underwent cardiac catheterization for stable coronary artery disease (n = 10) or acute myocardial infarction (n = 44) had simultaneous intracoronary pressure, Doppler flow velocity and thermodilution flow data acquired from 74 unobstructed vessels, at rest and during hyperemia. Three independent measurements of microvascular function were assessed, using predefined dichotomous thresholds: (1) coronary flow reserve (CFR), the average value of Doppler- and thermodilution-derived CFR; (2) cardiovascular magnetic resonance (CMR) derived myocardial perfusion reserve index; and (3) CMR-derived microvascular obstruction. hMR correlated with IMR (rho = 0.41, p

IntroductionKnee and hip osteoarthritis (OA) is a leading cause of disability worldwide. Therapeutic exercise is a recommended core treatment for people with knee and hip OA, however, the observed effect sizes for reducing pain and improving physical function are small to moderate. This may be due to insufficient targeting of exercise to subgroups of people who are most likely to respond and/or suboptimal content of exercise programmes. This study aims to identify: (1) subgroups of people with knee and hip OA that do/do not respond to therapeutic exercise and to different types of exercise and (2) mediators of the effect of therapeutic exercise for reducing pain and improving physical function. This will enable optimal targeting and refining the content of future exercise interventions.Methodsand analysisSystematic review and individual participant data meta-analyses. A previous comprehensive systematic review will be updated to identify randomised controlled trials that compare the effects of therapeutic exercise for people with knee and hip OA on pain and physical function to a non-exercise control. Lead authors of eligible trials will be invited to share individual participant data. Trial-level and participant-level characteristics (for baseline variables and outcomes) of included studies will be summarised. Meta-analyses will use a two-stage approach, where effect estimates are obtained for each trial and then synthesised using a random effects model (to account for heterogeneity). All analyses will be on an intention-to-treat principle and all summary meta-analysis estimates will be reported as standardised mean differences with 95% CI.Ethics and disseminationResearch ethical or governance approval is exempt as no new data are being collected and no identifiable participant information will be shared. Findings will be disseminated via national and international conferences, publication in peer-reviewed journals and summaries posted on websites accessed by the public and clinicians.PROSPERO registration numberCRD42017054049.

Counselor competence in telephone Motivation Interviewing (MI) to change lifestyle behaviors in a primary care population was assessed using the Motivational Interviewing Treatment Integrity (MITI) rating system. Counselor behavior was evaluated by trained raters. Twenty minutes of a random sample of 336 MI sessions were coded representing 232 counselees. Ninety-four sessions (28%) were double coded to assess inter-rater agreement. The MI fidelity was examined by comparing the MI fidelity scores direction, empathy, spirit, % open questions, % complex reflections, reflections-to-questions ratio, % MI-adherent responses with the matching beginner proficiency MITI threshold.The inter-rater agreements for the MI fidelity summary scores were good (spirit, reflections-to-questions ratio), fair (empathy, % open questions, % MI-adherent responses) or poor (direction, % complex reflection). The MI fidelity scores for direction, empathy, spirit and the percentage of complex reflections exceeded the MITI threshold, but lower scores were found for the percentage of open questions, the reflections-to-questions ratio and the percentage of MI-adherent responses.In conclusion, evidence that MI was implemented was revealed. However, the inter-rater agreements scores and some fidelity scores leave room for improvement indicating that raters and counselors may need more ongoing training and feedback to achieve and maintain adequate competence. These findings apply to more complex skills (as rating complex reflections) in particular.

Objectiveto quantify to what extent evidence-based health behaviour topics relevant for pregnancy are discussed with clients during midwife-led prenatal booking visits and to assess the association of client characteristics with the extent of information provided.Designquantitative video analyses.Setting and participants173 video recordings of prenatal booking visits with primary care midwives and clients in the Netherlands taking place between August 2010 and April 2011.Measurementsthirteen topics regarding toxic substances, nutrition, maternal weight, supplements, and health promoting activities were categorized as either ‘never mentioned’, ‘briefly mentioned’, ‘basically explained’ or ‘extensively explained’. Rates on the extent of information provided were calculated for each topic and relationships between client characteristics and dichotomous outcomes of the extent of information provided were assessed using Generalized Linear Mixed Modelling.Findingsour findings showed that women who did not take folic acid supplementation, who smoked, or had a partner who smoked, were usually provided basic and occasionally extensive explanations about these topics. The majority of clients were provided with no information on recommended weight gain (91.9%), fish promotion (90.8%), caffeine limitation (89.6%), vitamin D supplementation (87.3%), physical activity promotion (81.5%) and antenatal class attendance (75.7%) and only brief mention of alcohol (91.3%), smoking (81.5%), folic acid (58.4) and weight at the start of pregnancy (52.0%). The importance of a nutritious diet was generally either never mentioned (38.2%) or briefly mentioned (45.1%). Nulliparous women were typically given more information on most topics than multiparous women.Key conclusions and implications for practice:although additional information was generally provided about folic acid and smoking, when relevant for their clients, the majority of women were provided with little or no information about the other health behaviours examined in this study. Midwives may be able to improve prenatal health promotion by providing more extensive health behaviour information to their clients during booking visits.

BACKGROUND: Instructing and guiding patients after surgery is essential for successful recovery. However, the time that health-care professionals can spend with their patients postoperatively has been reduced because of efficiency-driven, shortened hospital stays. We evaluated the effect of a personalised e-health-care programme on return to normal activities after surgery.METHODS: A multicentre, single-blind, randomised controlled trial was done at seven teaching hospitals in the Netherlands. Patients aged 18-75 years who were scheduled for laparoscopic cholecystectomy, inguinal hernia surgery, or laparoscopic adnexal surgery for a benign indication were recruited. An independent researcher randomly allocated participants to either the intervention or control group using computer-based randomisation lists, with stratification by sex, type of surgery, and hospital. Participants in the intervention group had access to a perioperative, personalised, e-health-care programme, which managed recovery expectations and provided postoperative guidance tailored to the patient. The control group received usual care and access to a placebo website containing standard general recovery advice. Participants were unaware of the study hypothesis and were asked to complete questionnaires at five timepoints during the 6-month period after surgery. The primary outcome was time between surgery and return to normal activities, measured using personalised patient-reported outcome measures. Intention-to-treat and per-protocol analyses were done. This trial is registered in the Netherlands National Trial Register, number NTR4699.FINDINGS: Between Aug 24, 2015, and Aug 12, 2016, 344 participants were enrolled and randomly allocated to either the intervention (n=173) or control (n=171) group. 14 participants (4%) were lost to follow-up, with 330 participants included in the primary outcome analysis. Median time until return to normal activities was 21 days (95% CI 17-25) in the intervention group and 26 days (20-32) in the control group (hazard ratio 1·38, 95% CI 1·09-1·73; p=0·007). Complications did not differ between groups.INTERPRETATION: A personalised e-health intervention after abdominal surgery speeds up the return to normal activities compared with usual care. Implementation of this e-health programme is recommended in patients undergoing intermediate-grade abdominal, gynaecological, or general surgical procedures.FUNDING: ZonMw.

BackgroundThe utilisation of available cross-European data for secondary data analyses on physical activity, sedentary behaviours and their underlying determinants may benefit from the wide variation that exists across Europe in terms of these behaviours and their determinants. Such reuse of existing data for further research requires Findable; Accessible; Interoperable; Reusable (FAIR) data management and stewardship. We here describe the inventory and development of a comprehensive European dataset compendium and the process towards cross-European secondary data analyses of pooled data on physical activity, sedentary behaviour and their correlates across the life course.MethodsA five-step methodology was followed by the European Determinants of Diet and Physical Activity (DEDIPAC) Knowledge Hub, covering the (1) identification of relevant datasets across Europe, (2) development of a compendium including details on the design, study population, measures and level of accessibility of data from each study, (3) definition of key topics and approaches for secondary analyses, (4) process of gaining access to datasets and (5) pooling and harmonisation of the data and the development of a data harmonisation platform.ResultsA total of 114 unique datasets were found for inclusion within the DEDIPAC compendium. Of these datasets, 14 were eventually obtained and reused to address 10 exemplar research questions. The DEDIPAC data harmonisation platform proved to be useful for pooling, but in general, harmonisation was often restricted to just a few core (crude) outcome variables and some individual-level sociodemographic correlates of these behaviours.ConclusionsObtaining, pooling and harmonising data for secondary data analyses proved to be difficult and sometimes even impossible. Compliance to FAIR data management and stewardship principles currently appears to be limited for research in the field of physical activity and sedentary behaviour. We discuss some of the reasons why this might be the case and present recommendations based on our experience.

This study explored the cost-effectiveness and return-on-investment of a combined social and physical environmental worksite health promotion program compared with usual practice, and of both intervention conditions separately. Participants were randomized to the combined intervention (n = 92), social environmental intervention (n = 118), physical environmental intervention (n = 96), or control group (n = 106). The social environmental intervention consisted of group motivational interviewing and the physical environmental intervention of workplace modifications. Both interventions were aimed at improving physical activity and relaxation. Effects included need for recovery (NFR), general vitality and job satisfaction. Cost-effectiveness analyses were performed from the societal and employer's perspective, and return-on-investment analyses from the employer's perspective. Compared with usual practice, the combined intervention was significantly more effective in improving NFR (-8.4;95% CI:-14.6;-2.2) and significantly more expensive to the employer (3102; 95%CI:598;5969). All other between-group differences were non-significant. For NFR, the combined intervention became the preferred option at willingness-to-pays of ≥€170/point improvement (society) and ≥€300/point improvement (employer). For general vitality and job satisfaction, the interventions' maximum probabilities of cost-effective were low (≤0.55). All interventions had a negative return-on-investment. The combined intervention may be cost-effective for NFR depending on the decision-makers' willingness-to-pay. Both separate interventions are not cost-effective for NFR. All interventions were neither cost-effective for general vitality and job satisfaction, nor cost-saving to the employer.

Aims/hypothesis: Accurate prevalence estimates for gestational diabetes mellitus (GDM) among pregnant women in Europe are lacking owing to the use of a multitude of diagnostic criteria and screening strategies in both high-risk women and the general pregnant population. Our aims were to report important risk factors for GDM development and calculate the prevalence of GDM in a cohort of women with BMI ≥29 kg/m2 across 11 centres in Europe using the International Association of the Diabetes and Pregnancy Study Groups (IADPSG)/WHO 2013 diagnostic criteria. Methods: Pregnant women (n = 1023, 86.3% European ethnicity) with a BMI ≥29.0 kg/m2 enrolled into the Vitamin D and Lifestyle Intervention for GDM Prevention (DALI) pilot, lifestyle and vitamin D studies of this pan-European multicentre trial, attended for an OGTT during pregnancy. Demographic, anthropometric and metabolic data were collected at enrolment and throughout pregnancy. GDM was diagnosed using IADPSG/WHO 2013 criteria. GDM treatment followed local policies. Results: The number of women recruited per country ranged from 80 to 217, and the dropout rate was 7.1%. Overall, 39% of women developed GDM during pregnancy, with no significant differences in prevalence across countries. The prevalence of GDM was high (24%; 242/1023) in early pregnancy. Despite interventions used in the DALI study, a further 14% (94/672) had developed GDM when tested at mid gestation (24–28 weeks) and 13% (59/476) of the remaining cohort at late gestation (35–37 weeks). Demographics and lifestyle factors were similar at baseline between women with GDM and those who maintained normal glucose tolerance. Previous GDM (16.5% vs 7.9%, p = 0.002), congenital malformations (6.4% vs 3.3%, p = 0.045) and a baby with macrosomia (31.4% vs 17.9%, p = 0.001) were reported more frequently in those who developed GDM. Significant anthropometric and metabolic differences were already present in early pregnancy between women who developed GDM and those who did not. Conclusions/interpretation: The prevalence of GDM diagnosed by the IADPSG/WHO 2013 GDM criteria in European pregnant women with a BMI ≥29.0 kg/m2 is substantial, and poses a significant health burden to these pregnancies and to the future health of the mother and her offspring. Uniform criteria for GDM diagnosis, supported by robust evidence for the benefits of treatment, are urgently needed to guide modern GDM screening and treatment strategies.

Background and Objectives The aim was to systematically review whether the reporting and analysis of trial-based cost-effectiveness evaluations in the field of obstetrics and gynaecology comply with guidelines and recommendations, and whether this has improved over time. Data Sources and Selection Criteria A literature search was performed in MEDLINE, the NHS Economic Evaluation Database (NHS EED) and the Health Technology Assessment (HTA) database to identify trial-based cost-effectiveness evaluations in obstetrics and gynaecology published between January 1, 2000 and May 16, 2017. Studies performed in middle- and low-income countries and studies related to prevention, midwifery, and reproduction were excluded. Data Collection and Analysis Reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standard (CHEERS) statement (a modified version with 21 items, as we focused on trial-based cost-effectiveness evaluations) and the statistical quality was assessed using a literature-based list of criteria (8 items). Exploratory regression analyses were performed to assess the association between reporting and statistical quality scores and publication year. Results The electronic search resulted in 5482 potentially eligible studies. Forty-five studies fulfilled the inclusion criteria, 22 in obstetrics and 23 in gynaecology. Twenty-seven (60%) studies did not adhere to 50% (n = 10) or more of the reporting quality items and 32 studies (71%) did not meet 50% (n = 4) or more of the statistical quality items. As for the statistical quality, no study used the appropriate method to assess cost differences, no advanced methods were used to deal with missing data, and clustering of data was ignored in all studies. No significant improvements over time were found in reporting or statistical quality in gynaecology, whereas in obstetrics a significant improvement in reporting and statistical quality was found over time. Limitations The focus of this review was on trial-based cost-effectiveness evaluations in obstetrics and gynaecology, so further research is needed to explore whether results from this review are generalizable to other medical disciplines. Conclusions and Implications of Key Findings The reporting and analysis of trial-based cost-effectiveness evaluations in gynaecology and obstetrics is generally poor. Since this can result in biased results, incorrect conclusions, and inappropriate healthcare decisions, there is an urgent need for improvement in the methods of cost-effectiveness evaluations in this field.

INTRODUCTION\ud \ud Better mental health has been associated with exposure to natural outdoor environments (NOE). However, comprehensive studies including several indicators of exposure and outcomes, potential effect modifiers and mediators are scarce.\ud \ud OBJECTIVES\ud \ud We used novel, objective measures to explore the relationships between exposure to NOE (i.e. residential availability and contact) and different indicators of mental health, and possible modifiers and mediators.\ud \ud METHODS\ud \ud A nested cross-sectional study was conducted in: Barcelona, Spain; Stoke-on-Trent, United Kingdom; Doetinchem, Netherlands; Kaunas, Lithuania. Participants' exposure to NOE (including both surrounding greenness and green and/or blue spaces) was measured in terms of (a) amount in their residential environment (using Geographical Information Systems) and (b) their contact with NOE (using smartphone data collected over seven days). Self-reported information was collected for mental health (psychological wellbeing, sleep quality, vitality, and somatisation), and potential effect modifiers (gender, age, education level, and city) and mediators (perceived stress and social contacts), with additional objective NOE physical activity (potential mediator) derived from smartphone accelerometers.\ud \ud RESULTS\ud \ud Analysis of data from 406 participants showed no statistically significant associations linking mental health and residential NOE exposure. However, NOE contact, especially surrounding greenness, was statistically significantly tied to better mental health. There were indications that these relationships were stronger for males, younger people, low-medium educated, and Doetinchem residents. Perceived stress was a mediator of most associations, and physical activity and social contacts were not.\ud \ud CONCLUSIONS\ud \ud Our findings indicate that contact with NOE benefits mental health. Our results also suggest that having contact with NOE that can facilitate stress reduction could be particularly beneficial.

Objectives: The objectives of this study are to investigate the relation between obesity and labour force exit via diagnosis-specific disability benefits, and whether physical workload modifies this association. Methods: A longitudinal analysis was performed among 3 28 743 Swedish construction workers in the age of 15-65 years. Body weight and height were measured at a health examination and enriched with register information on disability benefits up to 37 years later. Diagnoses of disability benefits were categorised into cardiovascular diseases (CVDs), musculoskeletal diseases (MSDs), mental disorders and others. A job exposure matrix, based on self-reported lifting of heavy loads and working in bent forward or twisted position, was applied as a measure of physical workload. Cox proportional hazards regression analyses were performed, and the relative excess risk due to interaction (RERI) between obesity and physical workload was calculated. Results: Obese construction workers were at increased risk of receiving disability benefits (HR 1.70, 95% CI 1.65 to 2.76), mainly through CVD (HR 2.30) and MSD (HR 1.71). Construction workers with a high physical workload were also more likely to receive a disability benefit (HR 2.28, 95% CI 2.21 to 2.34), particularly via MSD (HR 3.02). Obesity in combination with a higher physical workload increased the risk of disability benefits (RERI 0.28) more than the sum of the risks of obesity and higher physical workload, particularly for MSD (RERI 0.44). Conclusions: Obesity and a high physical workload are risk factors for disability benefit. Furthermore, these factors are synergistic risk factors for labour force exit via disability benefit through MSD. Comprehensive programmes that target health promotion to prevent obesity and ergonomic interventions to reduce physical workload are important to facilitate sustained employment.

Too much sitting (extended sedentary time) is recognized as a public health concern in Europe and beyond. Time spent sedentary is influenced and conditioned by clusters of individual-level and contextual (upstream) factors. Identifying population subgroups that sit too much could help to develop targeted interventions to reduce sedentary time. We explored the relative importance of socio-demographic correlates of sedentary time in adults across Europe. We used data from 26,617 adults who participated in the 2013 Special Eurobarometer 412 “Sport and physical activity”. Participants from all 28 EU Member States were randomly selected and interviewed face-to-face. Self-reported sedentary time was dichotomized into sitting less or > 7.5 h/day. A Chi-squared Automatic Interaction Detection (CHAID) algorithm was used to create a tree that hierarchically partitions the data on the basis of the independent variables (i.e., socio-demographic factors) into homogeneous (sub)groups with regard to sedentary time. This allows for the tentative identification of population segments at risk for unhealthy sedentary behaviour. Overall, 18.5% of the respondents reported sitting > 7.5 h/day. Occupation was the primary discriminator. The subgroup most likely to engage in extensive sitting were higher educated, had white-collar jobs, reported no difficulties with paying bills, and used the internet frequently. Clear socio-demographic profiles were identified for adults across Europe who engage in extended sedentary time. Furthermore, physically active participants were consistently less likely to engage in longer daily sitting times. In general, those with more indicators of higher wealth were more likely to spend more time sitting.

Context: Recurrence rates for ankle sprains are high. Therefore, preventive measures such as ankle bracing during sports are recommended. Objective: To systematically evaluate the perceived ease of use, quality, comfort, stability, and hindrance of and the overall satisfaction with 3 contemporary brace types in 3 types of sports. Design: Randomized comparative user survey. Setting: Recreational sports: soccer, volleyball, and running. Patients or Other Participants: Young adult recreational athletes (29 soccer players, 26 volleyball players, and 31 runners). Intervention(s): Compression brace (CB), lace-up brace (LB), and semirigid brace (SB). Main Outcome Measure(s): Rating of perceived ease of use, quality, comfort, stability, and hindrance of and overall satisfaction with the brace types during sports on a 5-point Likert scale. The secondary outcome measure was participants' willingness to buy the tested brace. Results: Overall, the 3 brace types received high mean scores for ease of use and quality. Soccer players preferred the CB over both alternatives, considering the higher scores for comfort (CB = 4.0, LB = 3.5, SB = 2.8), hindrance (CB = 3.7, LB = 2.9, SB = 2.8), overall satisfaction (CB = 3.6, LB = 3.0, SB = 2.5), and greatest willingness to buy this brace. Volleyball players preferred the LB over both alternatives, considering the higher scores for stability (LB = 4.2, CB = 3.2, SB = 3.3), overall satisfaction (LB = 3.8, CB = 3.0, SB = 3.0), and greatest willingness to buy this brace. Runners preferred the CB over both alternatives considering the better score for hindrance (CB = 3.6, LB = 2.8, SB = 2.9) and greatest willingness to buy this brace. Conclusions: All 3 ankle-brace types scored high on perceived ease of use and quality. Regarding the brace types, soccer players, volleyball players, and runners differed in their assessments of subjective evaluation of comfort, stability, hindrance, overall satisfaction, and willingness to buy the brace. Soccer players and runners preferred the CB, whereas volleyball players preferred the LB.

Background: Polypharmacy is common in the elderly population and is associated with an increased risk of adverse drug events. To diminish this risk, the guideline 'Polypharmacy in the Elderly' has been developed in 2012. This study examines, to what extent Dutch pharmacotherapeutic practice amongst elderly with polypharmacy mirrors the best practice described in this guideline and which barriers threaten it. Methods: An observational study was conducted in 2013/14 using a questionnaire distributed amongst Dutch healthcare professionals and elderly patients with polypharmacy. Healthcare professionals were asked about their current practice and the presence of five significant barriers, selected through a literature review and from expert opinion. These barriers are: inadequate transfer of patient records; insufficient documentation of prescribed drugs; a lack of collaboration between professionals; a failure to take a full control of the medication and insufficient involvement of the patient. The patients were asked about their experience with pharmacotherapeutic care. Results: No more than 26% of the healthcare professionals indicated that they use the guideline. The five barriers threatening the pharmacotherapeutic care were found to be present. Fortythree percent of the patients mentioned that their medication was assessed last year. Conclusion: The guideline is not used frequently by the healthcare professionals, but there is a will to improve the care by following this guideline. However, the presence of the five barriers hampers its implementation. Good management of those barriers is necessary in order to improve the collaboration between primary and secondary care and to enhance the documentation of prescribed drugs.

Elevated blood pressure is a major risk factor for cardiovascular disease and has a substantial genetic contribution. Genetic variation influencing blood pressure has the potential to identify new pharmacological targets for the treatment of hypertension. To discover additional novel blood pressure loci, we used 1000 Genomes Project–based imputation in 150 134 European ancestry individuals and sought significant evidence for independent replication in a further 228 245 individuals. We report 6 new signals of association in or near HSPB7 , TNXB , LRP12 , LOC283335 , SEPT9 , and AKT2 , and provide new replication evidence for a further 2 signals in EBF2 and NFKBIA . Combining large whole-blood gene expression resources totaling 12 607 individuals, we investigated all novel and previously reported signals and identified 48 genes with evidence for involvement in blood pressure regulation that are significant in multiple resources. Three novel kidney-specific signals were also detected. These robustly implicated genes may provide new leads for therapeutic innovation.

Background: This single blind, multicenter randomized controlled trial aimed to evaluate the effectiveness of a supervised high intensity exercise program on physical fitness and fatigue in patients with multiple myeloma or lymphoma recently treated with autologous stem cell transplantation. Methods: 109 patients were randomly assigned to the 18-week exercise intervention or the usual care control group. The primary outcomes included physical fitness (VO2peak and Wpeak determined using a cardiopulmonary exercise test; grip strength and the 30s chair stand test) and fatigue (Multidimensional Fatigue Inventory) and were assessed prior to randomization and after completion of the intervention or at similar time points for the control group. Multivariable multilevel linear regression analyses were performed to assess intervention effects. Results: Patients in the intervention group attended 86% of the prescribed exercise sessions. Of the patients in the control group, 47% reported ≥10 physiotherapy sessions, which most likely included supervised exercise, suggesting a high rate of contamination. Median improvements in physical fitness ranged between 16 and 25% in the intervention group and between 12 and 19% in the control group. Fatigue decreased in both groups. There were no significant differences between the intervention and control group. Conclusion: We found no significant beneficial effects of the supervised high intensity exercise program on physical fitness and fatigue when compared to usual care. We hypothesized that the lack of significant intervention effects may relate to suboptimal timing of intervention delivery, contamination in the control group and/or suboptimal compliance to the prescribed exercise intervention.

Background Although data from electronic health records (EHR) are often used for research purposes, systematic validation of these data prior to their use is not standard practice. Existing validation frameworks discuss validity concepts without translating these into practical implementation steps or addressing the potential influence of linking multiple sources. Therefore we developed a practical approach for validating routinely collected data from multiple sources and to apply it to a blood transfusion data warehouse to evaluate the usability in practice. Methods The approach consists of identifying existing validation frameworks for EHR data or linked data, selecting validity concepts from these frameworks and establishing quantifiable validity outcomes for each concept. The approach distinguishes external validation concepts (e.g. concordance with external reports, previous literature and expert feedback) and internal consistency concepts which use expected associations within the dataset itself (e.g. completeness, uniformity and plausibility). In an example case, the selected concepts were applied to a transfusion dataset and specified in more detail. Results Application of the approach to a transfusion dataset resulted in a structured overview of data validity aspects. This allowed improvement of these aspects through further processing of the data and in some cases adjustment of the data extraction. For example, the proportion of transfused products that could not be linked to the corresponding issued products initially was 2.2% but could be improved by adjusting data extraction criteria to 0.17%. Conclusions This stepwise approach for validating linked multisource data provides a basis for evaluating data quality and enhancing interpretation. When the process of data validation is adopted more broadly, this contributes to increased transparency and greater reliability of research based on routinely collected electronic health records.

The authors regret that in the above article a misprint appears in table two presenting the evidence synthesis stratified by main type of sedentary behaviour and overall sedentary time: Not all high quality studies were printed in bold letter type. The correct Table is shown on page 2. 2 Evidence synthesis stratified by main type of sedentary behaviour and overall sedentary time (Table presented.) Bold indicates a high-quality study. *Note that the amount of studies under the stratified evidence synthesis do not count up in het combined evidence synthesis, due to two reasons. First, some studies examined types of sedentary behaviour that could not be classified in one of the four main types (e.g. subjective sitting time). As these additional types were only examined in its relationship with one health indicator, they were not considered as an additional main type of sedentary behaviour. Second, studies reporting relationships of more than one measurement type were counted once in the combined evidence synthesis, and were considered to add evidence when consistent findings were reported (i.e. ≥75% of the relationships showing results in the same direction). +, study adding evidence for a positive relationship; − study adding evidence for an inverse relationship; 0 study indicating no evidence for a relationship; BMI, body mass index; CRF, cardiorespiratory fitness; DBP, diastolic blood pressure; FMI, fat mass index; HC, hip circumference; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; MetS, metabolic syndrome; SBP, systolic blood pressure; SSF, sum of skinfolds; SLJ, standing long jump; TC/HDL-c, ratio of total cholesterol to high-density lipoprotein cholesterol; TG, triglycerides; TV, television; WC, waist circumference.

Contains fulltext : 175773.pdf (Publisher’s version ) (Open Access) BACKGROUND: When entering the dying phase, the nature of physical, psychosocial and spiritual care needs of people with dementia and their families may change. Our objective was to understand what needs to be in place to develop optimal palliative care services for the terminal phase in the face of a small evidence base. METHODS: In 2015-2016, we performed a mixed-methods qualitative study in which we (1) analysed the domains and recommendations from the European Association for Palliative Care (EAPC) dementia white paper and identified those with particular relevance for the terminal phase; (2) performed a series of focus group discussions with Dutch family caregivers of people with dementia in variable stages; (3) conducted interviews with experts involved in 15 special forms of terminal care for people with dementia in five countries. The terminal phase was defined as dying but because of the difficulty predicting it, we included advanced dementia. We initially analysed the three parts separately, followed by an integrated analysis of (1)-(3) to inform service development. RESULTS: (1) The EAPC domain of "avoiding overly aggressive, burdensome, or futile treatment" was regarded of particular relevance in the terminal phase, along with a number of recommendations that refer to providing of comfort. (2) Families preferred continuity in care and living arrangements. Despite a recognition that this was a time when they had complex support needs, they found it difficult to accept involvement of a large team of unfamiliar (professional) caregivers. Mostly, terminal care was preferred at the place of residence. (3) The expert interviews identified preferred, successful models in which a representative of a well-trained team has the time, authority and necessary expertise to provide care and education of staff and family to where people are and which ensure continuity of relationships with and around the patient. CONCLUSION: A mobile team that specializes in palliative care in dementia and supports professional and family caregivers is a promising model. Compared to transfer to a hospice in the last weeks or days, it has the potential to address the priorities of families and patients for continuity of care, relationships and specialist expertise.

Purpose Dietary behaviours may be influenced by perceptions of barriers to healthy eating. Using data from a large cross-European study (N = 5900), we explored associations between various perceived barriers to healthy eating and dietary behaviours among adults from urban regions in five European countries and examined whether associations differed across regions and socio-demographic backgrounds. Methods Frequency of consumption of fruit, vegetables, fish, fast food, sugar-sweetened beverages, sweets, breakfast and home-cooked meals were split by the median into higher and lower consumption. We tested associations between barriers (irregular working hours; giving up preferred foods; busy lifestyle; lack of willpower; price of healthy food; taste preferences of family and friends; lack of healthy options and unappealing foods) and dietary variables using multilevel logistic regression models. We explored whether associations differed by age, sex, education, urban region, weight status, household composition or employment. Results Respondents who perceived any barrier were less likely to report higher consumption of healthier foods and more likely to report higher consumption of fast food. ‘Lack of willpower’, ‘time constraints’ and ‘taste preferences’ were most consistently associated with consumption. For example, those perceiving lack of willpower ate less fruit [odds ratio (OR) 0.57; 95% confidence interval (CI) 0.50–0.64], and those with a busy lifestyle ate less vegetables (OR 0.54; 95% CI 0.47–0.62). Many associations differed in size, but not in direction, by region, sex, age and household composition. Conclusion Perceived ‘lack of willpower’, ‘time constraints’ and ‘taste preferences’ were barriers most strongly related to dietary behaviours, but the association between various barriers and lower intake of fruit and vegetables was somewhat more pronounced among younger participants and women.

Background: Both parents' and children's perception of children's weight status may be important predictors of slimming and energy-balance related behaviours, independent of children's actual weight status. Objectives: We examined the cross-sectional association of children's self-reported slimming and energy-balance related behaviours with children's (i) actual, (ii) self-perceived and (iii) parent-perceived weight status. Methods: Data of 10- to 12-year-old European children and their parents were used. Multilevel logistic and linear regression analyses were performed, adjusting for age, gender, parental weight controlling behaviours, education, marital status and ethnicity. Results: Independent of their actual weight status, a higher proportion of children reported slimming when they or their parents perceived them as too fat. Children's self-perceived weight status was more strongly associated with slimming than their parents' perception or their actual weight status. Moreover, children who perceive themselves as overweight reported less physical activity and more screen time. Children whose parents perceive them as overweight reported less physical activity. Conclusions: Children's own perception of their weight status appears to be more important for their self-reported slimming than their actual or their parent's perceptions of their weight status. Additionally, children's self-perceived weight status seems important in engaging more physical activity and reduces screen time.

Purpose: This study aimed to assess patient-reported levels of physical activity (PA) and its associations with health-related quality of life (HRQoL) adjusted for important demographic, lifestyle-related, and clinical factors, among head and neck (HNC) survivors. Methods: This cross-sectional study included 116 HNC survivors. PA was assessed with the Physical Activity Scale for the Elderly (PASE) and HRQoL with the EORTC-QLQ-C30 and EORTC-HN35. Associations were studied using univariable and multivariable regression analyses. Results: Median PASE score was 100.3 (interquartile range 65.1;170.8) of which 54% were household, 34% leisure-time, and 12% occupational activities. Younger HNC survivors had higher levels of PA. Higher PA was significantly associated with higher global QoL (p

AimThe aim of the present study was to explore if children who spend more time on screen-based sedentary behaviors (i.e.TV viewing and computer use) drink more sugar-sweetened soft drinks. The study also assessed whether these associations were independent of individual and home environmental correlates of soft drink consumption and whether they were moderated by parental education.MethodsData were collected from 7886 children participating in the EuropeaN Energy balance Research to prevent excessive weight Gain among Youth (ENERGY) survey conducted in eight European countries. Self-report questionnaires were used. Multilevel linear regression analyses with soft drink consumption as dependent variable, TV viewing and computer use as independent variables and age, gender, parental education, attitude towards soft drinks, self-efficacy, parental modelling, parental rules and home availability of soft drinks as covariates were conducted. Further interactions were tested to explore if these associations were moderated by parental education. Country-specific analyses were conducted.ResultsIn six of the eight included countries, a significant positive association was observed between TV viewing (min/day) and soft drink consumption (ml/day), independent of individual and home environmental correlates of soft drink consumption (B = 0.46 (0.26–0.66) in Greece, B = 0.77 (0.36–1.17) in Norway, B = 0.82 (0.12–1.51) in Hungary, B = 1.06 (0.67–1.46) in Spain, B = 1.21 (0.67–1.74) in Belgium and B = 1.49 (0.72–2.27) in Switzerland). There was no significant association between computer use and soft drink consumption in six of the eight included countries in the final models. Moderation effects of parental education in the association between TV viewing and soft drink consumption were found in Norway and Hungary, the association being stronger among those with low parental education.ConclusionsTV viewing appears to be independently associated with soft drink consumption and this association was moderated by parental education in two countries only. Reducing TV time might therefore favorably impact soft drink consumption.

Background Patients' preferences and expectations should be taken into account in treatment decision making in the last phase of life. Shared decision making (SDM) is regarded as a way to give the patient a central role in decision making. Little is known about how SDM is used in clinical practice in advanced cancer care. Objective To examine whether and how the steps of SDM can be recognized in decision making about second- and third-line chemotherapy. Methods Fourteen advanced cancer patients were followed over time using face-to-face in-depth interviews and observations of the patients' out-clinic visits. Interviews and outpatient clinic visits in which treatment options were discussed or decisions made were transcribed verbatim and analysed using open coding. Results Patients were satisfied with the decision-making process, but the steps of SDM were barely seen in daily practice. The creation of awareness about available treatment options by physicians was limited and not discussed in an equal way. Patients' wishes and concerns were not explicitly assessed, which led to different expectations about improved survival from subsequent lines of chemotherapy. Conclusion To reach SDM in daily practice, physicians should create awareness of all treatment options, including forgoing treatment, and communicate the risk of benefit and harm. Open and honest communication is needed in which patients' expectations and concerns are discussed. Through this, the difficult process of decision making in the last phase of life can be facilitated and the focus on the best care for the specific patient is strengthened.

Background Screening for, diagnosis and management of intrauterine growth restriction (IUGR) is often performed in multidisciplinary collaboration. However, variation in screening methods, diagnosis and management of IUGR may lead to confusion. In the Netherlands two monodisciplinary guidelines on IUGR do not fully align. To facilitate effective collaboration between different professionals in perinatal care, we undertook a Delphi study with uniform recommendations as our primary result, focusing on issues that are not aligned or for which specifications are lacking in the current guidelines. Methods We conducted a Delphi study in three rounds. A purposively sampled selection of 56 panellists participated: 27 representing midwife-led care and 29 obstetrician-led care. Consensus was defined as agreement between the professional groups on the same answer and among at least 70% of the panellists within groups. Results Per round 51 or 52 (91% - 93%) panellists responded. This has led to consensus on 27 issues, leading to four consensus based recommendations on screening for IUGR in midwife-led care and eight consensus based recommendations on diagnosis and eight on management in obstetrician-led care. The multidisciplinary project group decided on four additional recommendations as no consensus was reached by the panel. No recommendations could be made about induction of labour versus expectant monitoring, nor about the choice for a primary caesarean section. Conclusions We reached consensus on recommendations for care for IUGR within a multidisciplinary panel. These will be implemented in a study on the effectiveness and cost-effectiveness of routine third trimester ultrasound for monitoring fetal growth. Research is needed to evaluate the effects of implementation of these recommendations on perinatal outcomes.
