Background: To describe the societal costs during one year of follow-up among older adults seeking chiropractic care due to a new episode of low back pain (LBP), and to determine what factors predict high societal costs in this population. Methods: Prospective cohort study, within chiropractic private practices (n = 38) in the Netherlands. 223 people ≥ 55 years of age with a new episode of LBP seeking chiropractic care participated. The primary outcome was total societal costs. High societal costs were defined as patients with costs in the top 20th percentile. The final prediction models were obtained using forward selection. Results were presented for the total population and stratified for retirement status. The model's prognostic accuracy (Hosmer–Lemeshow X2, Nagelkerke's R2) and discriminative ability [area under the receiver operating curve (AUC)] were assessed, and the models were internally validated using bootstrapping. Results: The mean total annual societal cost per patient was €5297 [95% confidence interval (CI): 4191–6403]. The biggest cost driver was presenteeism (65% of total costs), and costs were higher among non-retired participants (€7759; 95% CI 6047–9470) than retired participants (€1892; 95% CI 1088–2695). In the total population, younger age [odds ratio (OR): 0.87 for each additional year; 95% CI 0.80–0.95], being male instead of female (OR 2.96; 95% CI 1.19–7.44), less alcohol intake (OR 0.49; 95% CI 0.20–1.19), working instead of retirement (OR 9.37; 95% CI 1.83–48.04), and more disability at baseline (OR 1.08; 95% CI 1.00–1.16) were found to be predictive of high societal costs. Working was found to be the strongest predictor for high societal costs. After internal validation, the model's fit was good, it's explained variance was moderate (28%) and their AUCs could be interpreted as moderate (0.85). For non-pensioners, the same predictive factors were identified as for the entire population. The costs for the retired participants showed too little variation to be able to predict high costs. Conclusions: This study estimated the mean total annual societal cost of older adults seeking chiropractic care due to a new episode of LBP at €5297 (95% CI 4191–6403).These costs were mainly due to high levels of presenteeism, and extensively differed based upon work status.

The aim of this study was to investigate the effect of Pivotal Response Treatment versus robot-assisted Pivotal Response Treatment on self-initiations of children with autism spectrum disorder and to explore the relation between self-initiations and collateral gains in general social-communicative skills. Forty-four participants with autism spectrum disorder aged 3-8 years (Pivotal Response Treatment: n=20, Pivotal Response Treatment + robot: n=24), who were recruited as part of a larger randomized controlled trial (number NL4487/NTR4712, https://www.trialregister.nl/trial/4487), were included. Self-initiations were blindly coded, assessing video probes of all parent-child sessions using an event-recording system. General social-communicative skills were assessed with the parent- and teacher-rated Social Responsiveness Scale during intervention and at 3-month follow-up. Results using linear mixed-effects models showed overall gains in self-initiations during both Pivotal Response Treatment intervention groups (estimate = 0.43(0.15), 95% confidence interval (CI): 0.13-0.73), with larger gains in functional self-initiations in children receiving robot-assisted Pivotal Response Treatment (estimate = -0.27(0.12), 95% confidence interval: -0.50 to -0.04). Growth in self-initiations was related to higher parent-rated social awareness at follow-up compared with baseline in the total sample (r=-0.44, p=0.011). The clinical implications of these findings, as well as directions for future research in the utility of Pivotal Response Treatment and robot assistance in autism spectrum disorder intervention, are discussed.

Background: In the Netherlands, university medical centres (UMCs) bear primary responsibility for conducting medical research and delivering highly specialized care. The TopCare program was a policy experiment lasting 4 years in which three non-academic hospitals received funding from the Dutch Ministry of Health to also conduct medical research and deliver highly specialized care in specific domains. This study investigates research collaboration outcomes for all Dutch UMCs and non-academic hospitals in general and, more specifically, for the domains in the non-academic hospitals participating in the TopCare program. Additionally, it explores the organizational boundary work employed by these hospitals to foster productive research collaborations. Methods: A mixed method research design was employed combining quantitative bibliometric analysis of publications and citations across all Dutch UMCs and non-academic hospitals and the TopCare domains with geographical distances, document analysis and ethnographic interviews with actors in the TopCare program. Results: Quantitative analysis shows that, over the period of study, international collaboration increased among all hospitals while national collaboration and single institution research declined slightly. Collaborative efforts correlated with higher impact scores, and international collaboration scored higher than national collaboration. A total of 60% of all non-academic hospitals' publications were produced in collaboration with UMCs, whereas almost 30% of the UMCs' publications were the result of such collaboration. Non-academic hospitals showed a higher rate of collaboration with the UMC that was nearest geographically, whereas TopCare hospitals prioritized expertise over geographical proximity within their specialized domains. Boundary work mechanisms adopted by TopCare hospitals included aligning research activities with organizational mindset (identity), bolstering research infrastructure (competence) and finding and mobilizing strategic partnerships with academic partners (power). These efforts aimed to establish credibility and attractiveness as collaboration partners. Conclusions: Research collaboration between non-academic hospitals and UMCs, particularly where this also involves international collaboration, pays off in terms of publications and impact. The TopCare hospitals used the program's resources to perform boundary work aimed at becoming an attractive and credible collaboration partner for academia. Local factors such as research history, strategic domain focus, in-house expertise, patient flows, infrastructure and network relationships influenced collaboration dynamics within TopCare hospitals and between them and UMCs.

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.

Purpose: Inconsistent results have been found on the impact of using crosswalks versus EQ-5D value sets on reimbursement decisions. We sought to further investigate this issue in a simulation study. Methods: Trial-based economic evaluation data were simulated for different conditions (depression, low back pain, osteoarthritis, cancer), severity levels (mild, moderate, severe), and effect sizes (small, medium, large). For all 36 scenarios, utilities were calculated using 3L and 5L value sets and crosswalks (3L to 5L and 5L to 3L crosswalks) for the Netherlands, the United States, and Japan. Utilities, quality-adjusted life years (QALYs), incremental QALYs, incremental cost-effectiveness ratios (ICERs), and probabilities of cost-effectiveness (pCE) obtained from values sets and crosswalks were compared. Results: Differences between value sets and crosswalks ranged from −0.33 to 0.13 for utilities, from −0.18 to 0.13 for QALYs, and from −0.01 to 0.08 for incremental QALYs, resulting in different ICERs. For small effect sizes, at a willingness-to-pay of €20,000/QALY, the largest pCE difference was found for moderate cancer between the Japanese 5L value set and 5L to 3L crosswalk (difference = 0.63). For medium effect sizes, the largest difference was found for mild cancer between the Japanese 3L value set and 3L to 5L crosswalk (difference = 0.06). For large effect sizes, the largest difference was found for mild osteoarthritis between the Japanese 3L value set and 3L to 5L crosswalk (difference = 0.08). Conclusion: The use of crosswalks instead of EQ-5D value sets can impact cost–utility outcomes to such an extent that this may influence reimbursement decisions. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to explore whether oral feedback by inspectors of the Dutch Inspectorate of Education is an adequate method to support the professional development of teachers in primary education. This study aims to examine the impact of short feedback training for inspectors (focused on effective feedback conversations) on feedback quality and on teachers' feedback perception. In addition, it aims to study the relation between immediate perception and the delayed perception of that feedback. Design/methodology/approach: In an independent sample experimental design, 15 inspectors provided feedback to 40 teachers in primary education. Nine inspectors received short feedback training (the experimental group), while six others did not receive this training (the control group). Findings: The results indicate that feedback provided by trained inspectors can foster professional development of teachers in primary education and that short feedback training has added value. The quality of the feedback by inspectors was related to teachers' immediate perception of the feedback and the delayed perception of the feedback. Research limitations/implications: A limitation of this study is the small group of inspectors and the limited number of feedback conversations they could provide. Further research could be aimed at examining the impact of feedback of trained inspectors on the professional development of underperforming teachers. Originality/value: This paper contributes to research that examines effective ways to use feedback conversations in workplace settings for the professional development of teachers.

We examined to what extent children in The Netherlands are affected by the threat of terrorism. For this purpose, a sample of school children living in Rotterdam or adjacent satellites (N = 216) completed a fear survey that included a number of terrorism-related items, and were confronted with ambiguous vignettes to measure threat-related interpretation bias. The results demonstrated that although a number of terrorism-related items (i.e., bombing attacks, explosions in a bus or subway) listed high in a ranking of most intense childhood fears, very few children made terrorist-related interpretations of ambiguous situations.

Increasing prevalence of chronic disease leads to an increased need for person-centered care. To prepare future health professionals for this need, educational institutions provide interprofessional education in which they actively involve patients (hereafter called experts by experience). The organization of inter-institutional, interprofessional education with the active involvement of experts by experience poses challenges. To overcome these challenges, a joint student- and expert by experience-led organization was established, named Patient as a Person Foundation. This organization functions as the linking pin between three educational institutions. Jointly, they enabled the involvement of 181 experts by experience in interprofessional education and 1313 students from nine study programs over the course of two curriculum years. To facilitate joint education involving patients, Patient as a Person Foundation realizes three main activities: (a) recruitment and instruction of experts by experience, (b) enabling the inter-institutional organization of education and facilitating its logistics and financing, and (c) universal training of teaching staff. This interprofessional Education and Practice Guide aims to provide lessons on how to sustainably organize interprofessional education involving experts by experience across multiple educational institutions. The key lessons provided in this guide, underpinned by research and key literature, aim to inspire and enable similar initiatives elsewhere. [ABSTRACT FROM AUTHOR]

Background: The causal pathway between complications after pancreatic cancer resection and impaired long-term survival remains unknown. The aim of this study was to investigate the impact of complications after pancreatic cancer resection on disease-free interval and overall survival, with adjuvant chemotherapy as a mediator. Methods: This observational study included all patients undergoing pancreatic cancer resection in the Netherlands (2014–2017). Clinical data were extracted from the prospective Dutch Pancreatic Cancer Audit. Recurrence and survival data were collected additionally. In causal mediation analysis, direct and indirect effect estimates via adjuvant chemotherapy were calculated. Results: In total, 1071 patients were included. Major complications (hazards ratio 1.22 (95 per cent c.i. 1.04 to 1.43); P = 0.015 and hazards ratio 1.25 (95 per cent c.i. 1.08 to 1.46); P = 0.003) and organ failure (hazards ratio 1.86 (95 per cent c.i. 1.32 to 2.62); P < 0.001 and hazards ratio 1.89 (95 per cent c.i. 1.36 to 2.63); P < 0.001) were associated with shorter disease-free interval and overall survival respectively. The effects of major complications and organ failure on disease-free interval (−1.71 (95 per cent c.i. −2.27 to −1.05) and −3.05 (95 per cent c.i. −4.03 to −1.80) respectively) and overall survival (−1.92 (95 per cent c.i. −2.60 to −1.16) and −3.49 (95 per cent c.i. −4.84 to −2.03) respectively) were mediated by adjuvant chemotherapy. Additionally, organ failure directly affected disease-free interval (−5.38 (95 per cent c.i. −9.27 to −1.94)) and overall survival (−6.32 (95 per cent c.i. −10.43 to −1.99)). In subgroup analyses, the association was found in patients undergoing pancreaticoduodenectomy, but not in patients undergoing distal pancreatectomy. Conclusion: Major complications, including organ failure, negatively impact survival in patients after pancreatic cancer resection, largely mediated by adjuvant chemotherapy. Prevention or adequate treatment of complications and use of neoadjuvant treatment may improve oncological outcomes. This nationwide observational cohort study included 1052 patients and showed that major complications, including organ failure, have a negative impact on disease-free interval and overall survival after resection of pancreatic cancer. This effect was largely mediated by the use of adjuvant chemotherapy. [ABSTRACT FROM AUTHOR]

To evaluate the effect of incorporating calcium advice into early pregnancy counseling on calcium intake during pregnancy in the Netherlands. A multicenter prospective before-after cohort study was conducted introducing risk-based care including calculating individual pre-eclampsia risk. Part of the intervention was to incorporate calcium advice into routine counseling. We calculated individual daily calcium intake and adequacy of calcium intake (≥1,000 mg/day) at 16, 24 and 34 weeks of pregnancy. We performed a multiple logistic regression adjusting for covariates to identify any differences in the risk of inadequate calcium intake between RC and CAC. In regular care (RC, 2013–2015, n=2,477) 60% had inadequate calcium intake, compared to 49% during calcium advice care (CAC, 2017–2018, n=774) (aOR 0.75, 95% CI 0.64–0.88). Specific calcium supplements were used by 2% and 29% in RC and CAC, respectively (OR 25.1, 95% CI 17.8–36.0). Determinants of an inadequate calcium intake were lower age (aOR per additional year 0.96, 95% CI: 0.94–0.98), nulliparity (aOR 1.22, 95% CI: 1.03–1.45) and non-Caucasian origin (aOR 1.83, 95% CI 1.09–3.09). In CAC, risk of inadequate intake decreased with increasing predicted pre-eclampsia risk, which was a trend reversal compared to RC. Incorporating calcium advice into early pregnancy counseling was shown to lead to a decrease in the risk of inadequate calcium intake during pregnancy, but still inadequate intake in half of the women suggesting the need for further study on improving implementation. Awareness of individual increased PE risk had positive effect on calcium intake. [ABSTRACT FROM AUTHOR]

Background: Prescription opioid use has increased steadily in many Western countries over the past two decades, most notably in the US, Canada, and most European countries, including the Netherlands. Especially the increasing use of prescription opioids for chronic non-cancer pain has raised concerns. Most opioids in the Netherlands are prescribed in general practices. However, little is known about variation in opioid prescribing between general practices. To better understand this, we investigated practice variation in opioid prescribing for non-cancer pain between Dutch general practices. Methods: Data from 2017–2019 of approximately 10% of all Dutch general practices was used. Each year included approximately 1000000 patients distributed over approximately 380 practices. The primary outcome was the proportion of patients with chronic (>90 days) high-dose (≥90 oral morphine equivalents) opioid prescriptions. The secondary outcome was the proportion of patients with chronic (<90 oral morphine equivalents) opioid prescriptions. Practice variation was expressed as the ratio of the 95th/5th percentiles and the ratio of mean top 10/bottom 10. Funnel plots were used to identify outliers. Potential factors associated with unwarranted variation were investigated by comparing outliers on practice size, patient neighbourhood socioeconomic status, and urbanicity. Results: Results were similar across all years. The magnitude of variation for chronic high-dose opioid prescriptions in 2019 was 7.51-fold (95%/5% ratio), and 15.1-fold (top 10/bottom 10 ratio). The percentage of outliers in the funnel plots varied between 13.8% and 21.7%. Practices with high chronichigh-doseopioid prescription proportions were larger, and had more patients from lower income and densely populated areas. Conclusions: There might be unwarranted practice variation in chronic high-dose opioid prescriptions in primary care, pointing at possible inappropriate use of opioids. This appears to be related to socioeconomic status, urbanicity, and practice size. Further investigation of the factors driving practice variation can provide target points for quality improvement and reduce inappropriate care and unwarranted variation. [ABSTRACT FROM AUTHOR]

Background: A healthy lifestyle is indispensable for the prevention of noncommunicable diseases. However, lifestyle medicine is hampered by time constraints and competing priorities of treating physicians. A dedicated lifestyle front office (LFO) in secondary/tertiary care may provide an important contribution to optimize patient-centred lifestyle care and connect to lifestyle initiatives from the community. The LOFIT study aims to gain insight into the (cost-)effectiveness of the LFO. Methods: Two parallel pragmatic randomized controlled trials will be conducted for (cardio)vascular disorders (i.e. (at risk of) (cardio)vascular disease, diabetes) and musculoskeletal disorders (i.e. osteoarthritis, hip or knee prosthesis). Patients from three outpatient clinics in the Netherlands will be invited to participate in the study. Inclusion criteria are body mass index (BMI) ≥25 (kg/m2) and/or smoking. Participants will be randomly allocated to either the intervention group or a usual care control group. In total, we aim to include 552 patients, 276 in each trial divided over both treatment arms. Patients allocated to the intervention group will participate in a face-to-face motivational interviewing (MI) coaching session with a so-called lifestyle broker. The patient will be supported and guided towards suitable community-based lifestyle initiatives. A network communication platform will be used to communicate between the lifestyle broker, patient, referred community-based lifestyle initiative and/or other relevant stakeholders (e.g. general practitioner). The primary outcome measure is the adapted Fuster-BEWAT, a composite health risk and lifestyle score consisting of resting systolic and diastolic blood pressure, objectively measured physical activity and sitting time, BMI, fruit and vegetable consumption and smoking behaviour. Secondary outcomes include cardiometabolic markers, anthropometrics, health behaviours, psychological factors, patient-reported outcome measures (PROMs), cost-effectiveness measures and a mixed-method process evaluation. Data collection will be conducted at baseline, 3, 6, 9 and 12 months follow-up. Discussion: This study will gain insight into the (cost-)effectiveness of a novel care model in which patients under treatment in secondary or tertiary care are referred to community-based lifestyle initiatives to change their lifestyle.

Purpose Stress-related illnesses are prevalent in Western society, causing sick leave and putting a heavy economic burden on employers and society. For Dutch employers it is particularly relevant to have insight into the costs of absenteeism due to stress-related illness, as they are legally obligated to continue payment of wages. Therefore, this study assessed the duration and costs of an episode of sick leave due to stress-related illness for Dutch employers. Methods Data on sick leave due to various stress-related illnesses were obtained from a nationwide occupational health service database. Stress-related illnesses included tension complaints, burn-out, overexertion, and other reactions to stress. The duration per sick leave episode was estimated in working days, after which the average cost per sick leave period was estimated using age- and gender-specific price weights. Results During the study period, 16,676 employees took 17,338 episodes of sick leave due to stress-related illness. On average, one episode of sick leave lasted 101 working days, for which the costs for the employer were on average €19,151 per worker. Women were responsible for most episodes of sick leave and were on average 37 days more absent per episode compared to men. Moreover, of all kinds of stress-related illnesses, burn-out had the longest duration of sick leave with 313 calendar days and 163 working days, resulting in an average cost of €30,770. Conclusions Sick leave due to stress-related illness places a heavy burden on employers and thus society. Further research should be conducted on how to reduce this burden. [ABSTRACT FROM AUTHOR]

Background: This study examined the associations between accelerometer-derived sedentary time (ST), lower intensity physical activity (LPA), higher intensity physical activity (HPA) and the incidence of depressive symptoms over 4 years of follow-up. Methods: We included 2082 participants from The Maastricht Study (mean ± s.d. age 60.1 ± 8.0 years; 51.2% men) without depressive symptoms at baseline. ST, LPA and HPA were measured with the ActivPAL3 activity monitor. Depressive symptoms were measured annually over 4 years of follow-up with the 9-item Patient Health Questionnaire (PHQ-9). Cox regression analysis was performed to examine the associations between ST, LPA, HPA and incident depressive symptoms (PHQ-9 ⩾ 10). Analyses were adjusted for total waking time per day, age, sex, education level, type 2 diabetes mellitus, body mass index, total energy intake, smoking status and alcohol use. Results: During 7812.81 person-years of follow-up, 203 (9.8%) participants developed incident depressive symptoms. No significant associations [Hazard Ratio (95% confidence interval)] were found between sex-specific tertiles of ST (lowest v. highest tertile) [1.13 (0.76–1.66], or HPA (highest v. lowest tertile) [1.14 (0.78–1.69)] and incident depressive symptoms. LPA (highest v. lowest tertile) was statistically significantly associated with incident depressive symptoms in women [1.98 (1.19–3.29)], but not in men (p -interaction <0.01). Conclusions: We did not observe an association between ST or HPA and incident depressive symptoms. Lower levels of daily LPA were associated with an increased risk of incident depressive symptoms in women. Future research is needed to investigate accelerometer-derived measured physical activity and ST with incident depressive symptoms, preferably stratified by sex. [ABSTRACT FROM AUTHOR]

This study aimed at investigating nurse practitioners' self-efficacy and behavior in supporting self-management of patients with a progressive, life-threatening illness and their relatives. We adapted an existing validated instrument for this purpose, amongst other things by adding a seventh subscale "attention for relatives," and administered it in a nationwide, cross-sectional online survey among Dutch nurse practitioners. We analyzed associations between self-reported self-efficacy and behavior using Pearson correlations and paired sample t tests. Associations between self-efficacy and behavior with nurse practitioners' characteristics were examined using linear regression models. Most nurse practitioners (n = 327; 26% complete responses) were women (93%). Subscale and total scores for nurse practitioners' self-efficacy were moderately positively correlated with those for their behavior in self-management support. Subscale and total scores were statistically significantly higher for their self-efficacy than for their behavior. Increased work experience with patients with a progressive, life-threatening illness was associated with higher scores on self-efficacy and behavior in self-management support. We conclude that nurse practitioners are confident in their ability to support self-management; yet, they do not always use these competencies in practice. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate healthcare utilization and satisfaction with treatment before and after implementing direct discharge (DD) from the Emergency Department (ED) of patients with simple, stable musculoskeletal injuries. Methods: Patients with simple, stable musculoskeletal injuries were included in two Dutch hospitals, both level-2 trauma centers: OLVG and Sint Antonius (SA), before (pre-DD-cohort) and after implementing DD (DD-cohort). With DD, no routine follow-up appointments are scheduled after the ED visit, supported by information leaflets, a smartphone application and a telephone helpline. Outcomes included: secondary healthcare utilization (follow-up appointments and X-ray/CT/MRI); satisfaction with treatment (scale 1–10); primary healthcare utilization (general practitioner (GP) or physiotherapist visited, yes/no). Linear regression was used to compare secondary healthcare utilization for all patients and per injury subgroup. Satisfaction and primary healthcare utilization were analyzed descriptively. Results: A total of 2033 (OLVG = 1686; SA = 347) and 1616 (OLVG = 1396; SA = 220) patients were included in the pre-DD-cohort and DD-cohort, respectively. After DD, the mean number of follow-up appointments per patient reduced by 1.06 (1.13–0.99; p < 0.001) in OLVG and 1.07 (1.02–0.93; p < 0.001) in SA. Follow-up appointments reduced significantly for all injury subgroups. Mean number of follow-up X-rays per patient reduced by 0.17 in OLVG (p < 0.001) and 0.18 in SA (p < 0.001). Numbers of CT/MRI scans were low and comparable. In OLVG, mean satisfaction with treatment was 8.1 (pre-DD-cohort) versus 7.95 (DD-cohort), versus 7.75 in SA (DD-cohort only). In OLVG, 23.6% of pre-DD-cohort patients visited their GP, versus 26.1% in the DD-cohort, versus 13.3% in SA (DD-cohort only). Physiotherapist use was comparable. Conclusion: This study performed in a large population and additional hospital confirms earlier pilot results, i.e., that DD has the potential to effectively reduce healthcare utilization, while maintaining high levels of satisfaction. Level of evidence: II. [ABSTRACT FROM AUTHOR]

This study aims to test psychometric properties and factor invariance of the Reactive–Proactive Aggression Questionnaire (RPQ) for adults across five countries: Serbia (N = 409), Mauritius (N = 400), the United States (N = 389), the Netherlands (N = 372), and China (N = 325). The results supported the two–factor structure across country samples, with a marginal model fit in Mauritius. Results also supported the congruent factor structure of Reactive Aggression scale across countries, while the Proactive Aggression scale can be considered as equal across samples from Serbia, the United States, and China, but not from Mauritius and the Netherland. Among items from the Proactive Aggression scale, those referring to open aggression aimed at obtaining social status and dominance, frightening or harming others, obtained the highest loadings across all samples and could be considered as the good representatives of adult proactive aggression. This is the first study in which cross-cultural validation of the RPQ among adults has been tested and results suggested that there are some cultural differences in expression of proactive aggression.

Background: It is a matter of debate whether sodium and potassium intake are associated with heart disease. Further, the mechanisms underlying associations of sodium and potassium intake with cardiac events, if any, are not fully understood.Objectives: We examined cross-sectional associations of 24-h urinary sodium excretion (UNaE) and potassium excretion (UKE), as estimates of their intakes, with high-sensitivity cardiac troponins T (hs-cTnT) and I (hs-cTnI), and N-terminal pro-B-type natriuretic peptide (NT-proBNP), which are markers of cardiomyocyte injury and cardiac dysfunction.Methods: We included 2961 participants from the population-based Maastricht Study (mean ± SD age 59.8 ± 8.2 y, 51.9% men), who completed the baseline survey between November 2010 and September 2013. Associations were examined with restricted cubic spline linear regression analyses and ordinary linear regression analyses, adjusted for demographics, lifestyle, and cardiovascular disease (CVD) risk factors.Results: Median [IQR] 24-h UNaE and UKE were 3.7 [2.8-4.7] g/24 h and 3.0 [2.4-3.6] g/24 h, respectively. After adjustment for potential confounders, 24-h UNaE was not associated with hs-cTnT, hs-cTnI, and NT-proBNP concentrations. In contrast, after adjustment for potential confounders, lower 24-h UKE was nonlinearly associated with higher hs-cTnT and NT-proBNP. For example, as compared with the third/median quintile of 24-h UKE (range: 2.8-3.2 g/24 h), participants in the first quintile (range: 0.5-2.3 g/24 h) had 1.05 (95% CI: 0.99, 1.11) times higher hs-cTnT and 1.14 (95% CI: 1.03, 1.26) times higher NT-proBNP. Associations were similar after further adjustment for estimated glomerular filtration rate, albuminuria, blood pressure, and serum potassium.Conclusions: Twenty-four-hour UNaE was not associated with the studied cardiac biomarkers. In contrast, lower 24-h UKE was nonlinearly associated with higher hs-cTnT and NT-proBNP. This finding supports recommendations to increase potassium intake in the general population. In addition, it suggests that cardiac dysfunction and/or cardiomyocyte injury may underlie previously reported associations of lower potassium intake with CVD mortality. [ABSTRACT FROM AUTHOR]

The diagnosis of pancreatic ductal adenocarcinoma (PDAC) has an enormous impact on patients, and even more so if they are of younger age. It is unclear how their treatment and outcome compare to older patients. This study compares clinicopathological characteristics and overall survival (OS) of PDAC patients aged <60 years to older PDAC patients. This is a retrospective, population-based cohort study using Netherlands Cancer Registry data of patients diagnosed with PDAC (1 January 2015–31 December 2018). Kaplan–Meier curves and Cox proportional hazards models were used to assess OS. Overall, 10,298 patients were included, of whom 1551 (15%) were <60 years. Patients <60 years were more often male, had better performance status, less comorbidities and less stage I disease, and more often received anticancer treatment (67 vs. 33%, p < 0.001) than older patients. Patients <60 years underwent resection of the tumour more often (22 vs. 14%p < 0.001), more often received chemotherapy, and had a better median OS (6.9 vs. 3.3 months, p < 0.001) compared to older patients. No differences in median OS were demonstrated between both age groups of patients who underwent resection (19.7 vs. 19.4 months, p = 0.123), received chemotherapy alone (7.8 vs. 8.5 months, p = 0.191), or received no anticancer treatment (1.8 vs. 1.9 months, p = 0.600). Patients <60 years with stage-IV disease receiving chemotherapy had a somewhat better OS (7.5 vs. 6.3 months, p = 0.026). Patients with PDAC <60 years more often underwent resection despite less stage I disease and had superior OS. Stratified for treatment, however, survival was largely similar. [ABSTRACT FROM AUTHOR]

Background and Objectives: The EPISoDe (Experience Success in Donation) study investigated the effect of interventions on self‐reported vasovagal reactions (VVRs) in first‐time and novice (second to fourth donation) whole blood donors aged ≤30 years, demonstrating a 23% reduction of VVR from water drinking shortly before donation in the novice donors. Because donation experience and complications affect donor retention, we analysed intervention group donors' return for subsequent donation, a predefined secondary outcome. Materials and Methods: The interventions were as follows: 330 ml water, 500 ml water, ball squeezing before phlebotomy (placebo) and a control group. All donors received an online questionnaire about their experience within a week after donation. In the Netherlands, eligible donors are invited at least yearly depending on hospitals' needs. We analysed attendances within 421 days through return percentages and binomial logistic regression. Results: Of the 8300 EPISoDe participants, 6538 (78.8%) returned within 421 days. Return did not differ between the two water groups, whereas odds for return were significantly higher in both water and placebo intervention donors compared to the control group (odds ratio [OR] 1.14, 95% confidence interval [CI] 1.00–1.29 and 1.22, 1.05–1.43, respectively) after adjustment for occurrence of VVR, unsuccessful collection, gender and donation history. Staff‐recorded or self‐reported VVR at index donation was associated with reduced odds for return (OR 0.47, 95% CI 0.37–0.60 and OR 0.53, 95% CI 0.46–0.61, respectively). Conclusion: In this cohort of younger inexperienced blood donors, 78.8% returned for subsequent donation. Donors who received an active study intervention, either water or placebo, were more likely to return than control group donors. [ABSTRACT FROM AUTHOR]

Purpose: Existing literature on trauma tertiary survey (TTS) focusses on multitrauma patients. This study examines the yield of the TTS in trauma patients with minor (AIS 1) or moderate (AIS 2) injury for which immediate hospitalization is not strictly indicated. Method: A single center retrospective cohort study was performed in a level II trauma center. All hospitalized trauma patients with an abbreviate injury score (AIS) of one or two at the primary and secondary survey were included. The primary outcome was defined as any missed injury found during TTS (Type 1). Secondary outcomes were defined as any missed injury found after TTS but during admission (Type 2); overall missed injury rate; mortality and hospital length of stay. Results: Out of 388 included patients, 12 patients (3.1%) had a type 1 missed injury. ISS and alcohol consumption were associated with an increased risk for type 1 missed injuries (resp. OR = 1.4, OR = 5.49). A type 2 missed injury was only found in one patient. This concerned the only case of trauma related mortality. Approximately one out of five patients were admitted for more than 2 days. These patients were significantly older (66 vs. 41 years, p < 0.001), had a higher ISS (4 vs. 3, p = 0.007) and ASA score, 3–4 vs. 1–2 (42.5% vs. 12.6%, p < 0.001). Conclusion: TTS showed a low rate of missed injuries in trauma patients with minor or moderate injury. TTS helped to prevent serious damage in two out of 388 patients (0.5%). ISS and alcohol consumption were associated with finding missed injury during TTS. [ABSTRACT FROM AUTHOR]

Objectives: Self-management of patients with advanced cancer is challenging. Although healthcare professionals may play a crucial role in supporting these patients, scant scientific attention has been paid to their perspectives. Therefore, we examined healthcare professionals' views on self-management and self-management support in this population.Methods: We conducted qualitative interviews with 27 purposively sampled medical specialists (n = 6), nurse specialists (n = 6), general practitioners (n = 8) and homecare/ hospice nurses (n = 7) in the Netherlands. Transcripts were analysed using thematic analysis.Results: Healthcare professionals experienced self-management of patients with advanced cancer to be diverse, dynamic and challenging. They adopted instructive, collaborative and advisory roles in self-management support for this population. Whereas some professionals preferred or inclined towards one role, others indicated to switch roles, depending on the situation.Conclusions: Just like patients with advanced cancer, healthcare professionals differ in their views and approaches regarding self-management and self-management support in this population. Therefore, instructive, collaborative and advisory self-management support roles will all be useful under certain circumstances.Practice Implications: Healthcare professionals can support self-management by being aware of their own views and communicating these clearly to their patients and colleagues. Education in self-management support should include self-reflection skills and discuss the relation between self-management and professional care. [ABSTRACT FROM AUTHOR]

Background: Surgery for pelvic organ prolapse (POP) is associated with high recurrence rates. The costs associated with the treatment of recurrent POP are huge, and the burden from women who encounter recurrent POP, negatively impacts their quality of life. Estrogen therapy might improve surgical outcome for POP due to its potential beneficial effects. It is thought that vaginal estrogen therapy improves healing and long-term maintenance of connective tissue integrity. Hence, this study aims to evaluate the cost-effectiveness of perioperative vaginal estrogen therapy in postmenopausal women undergoing POP surgery.Methods: The EVA trial is a multi-center double-blind randomized placebo-controlled trial conducted in the Netherlands comparing the effectiveness and costs-effectiveness of vaginal estrogen therapy. This will be studied in 300 postmenopausal women undergoing primary POP surgery, with a POP-Q stage of ≥ 2. After randomization, participants administer vaginal estrogen cream or placebo cream from 4 to 6 weeks preoperative until 12 months postoperative. The primary outcome is subjective improvement of POP symptoms at 1 year follow-up, measured with the Patient Global Impression of Improvement (PGI-I) scale. Secondary outcomes are POP-Q anatomy in all compartments, re-interventions, surgery related complications, general and disease specific quality of life, sexual function, signs and complaints of vaginal atrophy, vaginal pH, adverse events, costs, and adherence to treatment. Follow up is scheduled at 6 weeks, 6 months and 12 months postoperative. Data will be collected using validated questionnaires and out-patient visits including gynecological examination performed by an independent gynecologist.Discussion: This study investigates whether perioperative vaginal estrogen will be cost-effective in the surgical treatment of POP in postmenopausal women. It is hypothesized that estrogen therapy will show a reduction in recurrent POP symptoms and a reduction in reoperations for POP, with subsequent improved quality of life among women and cost savings.

OBJECTIVES: Rotavirus vaccination has 87% to 100% effectiveness against severe rotavirus acute gastroenteritis (AGE) in healthy infants in high-income countries. Little is known whether infants with medical risk conditions (MRCs) are equally protected and if the vaccine is equally well tolerated. We conducted a quasi-experimental prospective multicenter before-after cohort study to assess the vaccine effectiveness (VE) and safety profile of the human rotavirus vaccine (HRV) among MRC infants that required prolonged or frequent postnatal care. METHODS: The Netherlands has no national rotavirus immunization program, but HRV was implemented in routine care for MRC infants in 13 Dutch hospitals. Participants in the before and after cohort, HRV unvaccinated and vaccinated, respectively, were followed for occurrence of (rotavirus) AGE. VE of at least 1 dose was estimated by using time-to-event analysis for severe rotavirus AGE. Vaccine-related serious adverse event (AEs) after HRV were retrieved systematically from medical charts. Solicited AEs after vaccinations were prospectively collected and compared between vaccination time points with or without HRV. RESULTS: In total, 1482 high-risk infants with MRC were enrolled, including 631 in the before and 851 in the after cohorts; 1302 infants were premature (88.3%), 447 were small for gestational age (30.2%), and 251 had at least 1 congenital disorder (17.0%). VE against severe rotavirus AGE was 30% (95% confidence interval [CI]: -36% to 65%). Overall, the observed number of rotavirus hospitalizations was low and not significantly different between the cohorts (2 and 2, respectively). The rate of vaccine-related serious AE was 0.24 per 100 vaccine doses. The adjusted risk ratio for any AE after HRV vaccination compared with other routine vaccinations was 1.09 (95% CI: 1.05 to 1.12) for concomitant administration and 0.91 (95% CI: 0.81 to 0.99) for single HRV administration. Gastrointestinal AEs were 10% more frequent after HRV. CONCLUSIONS: In contrast to previous findings among healthy term infants, in routine use, HRV offered limited protection to vulnerable medical risk infants. HRV is generally well tolerated in this group in single administration, but when coadministered with routine vaccines, it is associated with higher risk of (mostly gastrointestinal) AE. Our study highlights the importance of studying vaccine performance in subgroups of medically vulnerable infants. [ABSTRACT FROM AUTHOR]

Universal mass vaccination (UMV) against rotavirus has been implemented in many but not all European countries. This study investigated the impact of UMV on rotavirus incidence trends by comparing European countries with UMV: Belgium, England/Wales and Germany versus countries without UMV: Denmark and the Netherlands. For this observational retrospective cohort study, time series data (2001–2016) on rotavirus detections, meteorological factors and population demographics were collected. For each country, several meteorological and population factors were investigated as possible predictors of rotavirus incidence. The final set of predictors were incorporated in negative binomial models accounting for seasonality and serial autocorrelation, and time-varying incidence rate ratios (IRR) were calculated for each age group and country separately. The overall vaccination impact two years after vaccine implementation was estimated by pooling the results using a random effects meta-analyses. Independent t-tests were used to compare annual epidemics in the pre-vaccination and post-vaccination era to explore any changes in the timing of rotavirus epidemics. The population size and several meteorological factors were predictors for the rotavirus epidemiology. Overall, we estimated a 42% (95%-CI 23;56%) reduction in rotavirus incidence attributable to UMV. Strongest reductions were observed for age-groups 0-, 1- and 2-years (IRR 0.47, 0.48 and 0.63, respectively). No herd effect induced by UMV in neighbouring countries was observed. In all UMV countries, the start and/or stop and corresponding peak of the rotavirus season was delayed by 4–7 weeks. The introduction of rotavirus UMV resulted in an overall reduction of 42% in rotavirus incidence in Western European countries two years after vaccine introduction and caused a change in seasonal pattern. No herd effect induced by UMV neighbouring countries was observed for Denmark and the Netherlands. [ABSTRACT FROM AUTHOR]

Background: This study aimed to assess how Dutch neurologists and anesthesiologists diagnose and treat people with sciatica in secondary care and to evaluate their adherence to the newest guidelines. Methods: We conducted a cross-sectional survey. Respondents were asked about their current clinical practice related to sciatica. Three authors rated the respondents' adherence to the guidelines on a three-point Likert scale. Results: Eighty neurologists and 44 anesthesiologists completed the questionnaire. Neurologists diagnose their sciatica patients primarily using a magnetic resonance imaging (89%). Selective diagnostic nerve blocks are considered useful by 81% of the neurologists. Neurologists primarily treat patients with pain medication, and 40% of them think epidural steroid injections are effective in 40–60% of injected patients. Twenty-nine percent of neurologists refer patients to a neurosurgeon after 4 months. Anesthesiologists consider a selective diagnostic nerve root block to have a higher diagnostic value than mapping. The most reported side effect of epidural injections is exacerbation of pain (82%). Pulse radiofrequency is applied in 9–11% of acute cases. The results also indicate that Dutch neurologists and anesthesiologists follow an evidence-based approach that is strictly or broadly in line with the guideline. Conclusions: Neurologists treat sciatica patients initially with pain medication and physiotherapy, followed by epidural steroid injections and referral for surgery. Anesthesiologists treat sciatica patients with one or more steroid injections or may perform a selective nerve root block. Imaging, selective nerve root blocks, medication, physiotherapy, and pulse radiofrequency are topics of further research. [ABSTRACT FROM AUTHOR]

Background: Homeless people experience multiple health problems and early mortality. In the Netherlands, they can get shelter-based end-of-life care, but shelters are predominantly focused on temporary accommodation and recovery. Aim: To examine the characteristics of homeless people who reside at the end-of-life in shelter-based nursing care settings and the challenges in the end-of-life care provided to them. Design: A retrospective record study using both quantitative and qualitative analysis methods. Setting/participants: Two Dutch shelter-based nursing care settings. We included 61 homeless patients who died between 2009 and 2016. Results: Most patients had somatic (98%), psychiatric (84%) and addiction problems (90%). For 75% of the patients, the end of life was recognised and documented; this occurred 0–1253 days before death. For 26%, a palliative care team was consulted in the year before death. In the three months before death, 45% had at least three transitions, mainly to hospitals. Sixty-five percent of the patients died in the shelter, 27% in a hospital and 3% in a hospice. A quarter of all patients were known to have died alone. Documented care difficulties concerned continuity of care, social and environmental safety, patient–professional communication and medical-pharmacological alleviation of suffering. Conclusions: End-of-life care for homeless persons residing in shelter-based nursing care settings is characterised and challenged by comorbidities, uncertain prognoses, complicated social circumstances and many transitions to other settings. Multilevel end-of-life care improvements, including increased interdisciplinary collaboration, are needed to reduce transitions and suffering of this vulnerable population at the end of life.

Introduction: Cumulative disease burden may be associated with survival chances after out-of-hospital cardiac arrest (OHCA). The relative contributions of cumulative disease burden on survival rates at the pre-hospital and in-hospital phases of post-resuscitation care are unknown.Methods: The association between cumulative comorbidity burden as measured by the Charlson Comorbidity Index (CCI) and pre-hospital and in-hospital survival rates was studied using data (2010-2014) from a prospective OHCA registry in the Netherlands. The association between CCI and survival rate (overall survival [OHCA-hospital discharge], pre-hospital survival [OHCA-hospital admission] and in-hospital survival [hospital admission-hospital discharge]) was assessed using logistic regression analyses. The relative contributions of CCI on pre-hospital and in-hospital survival rates were determined using the Nagelkerke test.Results: We included 2510 OHCA patients aged ≥18y. CCI was significantly associated with overall survival rate (OR 0.71; 95%CI 0.61-0.83; P < 0.01). CCI was not associated with pre-hospital survival rate (OR 0.96; 95%CI 0.76-1.23; P = 0.92) whereas high CCI was significantly associated with low in-hospital survival rate (OR 0.41; 95%CI 0.27-0.62; P = 0.01). The relative contributions of CCI on pre-hospital and in-hospital survival were 1.1% and 8.1%, respectively.Conclusion: Pre-existing high comorbidity burden plays a modest role in reducing survival rate after OHCA, and only in the in-hospital phase. The present study offers data that may guide clinicians in discussing resuscitation options during advance care planning with patients with high comorbidity burden. This may be helpful in creating a patients' informed choice. [ABSTRACT FROM AUTHOR]

This study compares the five-level EuroQol five-dimension questionnaire (EQ-5D-5L) crosswalks and the 5L value sets for England, the Netherlands, and Spain and explores the implication of using one or the other for the results of cost-utility analyses. Data from two randomized controlled trials in depression and diabetes were used. Utility value distributions were compared, and mean differences in utility values between the EQ-5D-5L crosswalk and the 5L value set were described by country. Quality-adjusted life years (QALYs) were calculated using the area-under-the-curve method. Incremental cost-effectiveness ratios (ICERs) were calculated, and uncertainty around ICERs was estimated using bootstrapping and graphically shown in cost-effectiveness acceptability curves. For all countries investigated, utility value distributions differed between the EQ-5D-5L crosswalk and 5L value set. In both case studies, mean utility values were lower for the EQ-5D-5L crosswalk compared with the 5L value set in England and Spain, but higher in the Netherlands. However, these differences in utility values did not translate into relevant differences across utility estimation methods in incremental QALYs and the interventions' probability of cost-effectiveness. Thus, our results suggest that EQ-5D-5L crosswalks and 5L value sets can be used interchangeably in patients affected by mild or moderate conditions. Further research is needed to establish whether these findings are generalizable to economic evaluations among severely ill patients. [ABSTRACT FROM AUTHOR]

Aims: This study aimed to establish whether higher levels of glycated haemoglobin (HbA1c) are associated with increased sudden cardiac arrest (SCA) risk in non-diabetic individuals.Methods and Results: Case-control study in non-diabetic individuals (HbA1c < 6.5%) in the Netherlands. Cases were SCA patients with electrocardiogram (ECG)-documented ventricular fibrillation (VF, the predominant cause of SCA) and HbA1c measurements immediately after VF, prospectively included in September 2009-December 2012. Controls (up to 10 per case) were age/sex-matched non-SCA individuals, included in July 2006-November 2007. We studied 306 cases (56.4 ± 6.8 years, 79.1% male) and 1722 controls (54.0 ± 6.8 years, 64.8% male). HbA1c levels were higher in cases than in controls (5.8 ± 0.3% vs. 5.4 ± 0.3%, P < 0.001). The proportion of increased HbA1c (≥5.7%) was 63.1% in cases and 19.3% in controls (P < 0.001). Multivariate regression models indicated that increased HbA1c was associated with a > six-fold increased VF risk [adjusted odds ratio (ORadj) 6.74 (5.00-9.09)] and that 0.1% increase in HbA1c level was associated with 1.4-fold increase in VF risk, independent of concomitant cardiovascular risk factors. Increased VF risk at higher HbA1c is associated with acute myocardial infarction (MI) as cause of VF [OR 1.14 (1.04-1.24)], but the association between HbA1c and VF was similar in non-MI patients [OR 1.32 (1.21-1.44)] and MI patients [OR 1.47 (1.37-1.58)].Conclusion: Among non-diabetic individuals, risk of VF increased with rising HbA1c levels, independent of concomitant cardiovascular disease. Future studies should establish whether HbA1c level may be used as biomarker to recognize individuals at risk for VF. [ABSTRACT FROM AUTHOR]

Purpose: Adequate calcium intake during pregnancy is of major importance for the health of both mother and fetus. Up to date, evidence on the prevalence of inadequate calcium intake among pregnant women is sparse for Western countries, and it is unknown to what extent inadequate dietary calcium intake is adequately balanced by supplement use. The objective of this study was to estimate calcium intake from diet and supplement use during the early pregnancy in The Netherlands. Methods: As part of the Expect cohort study, 2477 pregnant women (8–16 weeks of gestation) completed an online questionnaire including questions on baseline characteristics, the use of calcium containing supplements, and a short food-frequency questionnaire (FFQ). Intake data were used to calculate median calcium intakes from diet, from supplements, and combined, and to compare these values with currently accepted requirement levels. Results: Forty-two percent of the pregnant women had a total calcium intake below the estimated average requirement of 800 mg/day. Median (interquartile range) calcium intake was 886 (611–1213) mg/day. Calcium or multivitamin supplements were used by 64.8% of the women at 8 weeks of gestation, with a median calcium content of 120.0 (60.0–200.0) mg/day. Prenatal vitamins were the most often used supplements (60.6%). Conclusions: Forty-two percent of Dutch pregnant women have an inadequate calcium intake. Supplements are frequently used, but most do not contain sufficient amounts to correct this inadequate intake. [ABSTRACT FROM AUTHOR]

Background: The number of people with multiple chronic conditions requiring primary care services increases. Professionals from different disciplines collaborate and coordinate care to deal with the complex health care needs. There is lack of information on current practices regarding interprofessional team (IPT) meetings.Objectives: This study aimed to improve our understanding of the process of interprofessional collaboration in primary care team meetings in the Netherlands by observing the current practice and exploring personal opinions.Methods: Qualitative study involving observations of team meetings and interviews with participants. Eight different IPT meetings (n = 8) in different primary care practices were observed by means of video recordings. Experiences were explored by conducting individual semi-structured interviews (n = 60) with participants (i.e. health care professionals from different disciplines) of the observed team meetings. The data were analysed by means of content analysis.Results: Most participants expressed favourable opinions about their team meetings. However, observations showed that team meetings were more or less hectic, and lacked a clear structure and team coordinator or leader. There appears to be a discrepancy between findings from observations and interviews. From the interviews, four main themes were extracted: (1) Team structure and composition, (2) Patient-centredness, (3) Interaction and (4) Attitude and motivation.Conclusion: IPT meetings could benefit from improvements in structure, patient-centredness and leadership by the chairpersons. Given the discrepancy between observations and interviews, it would appear useful to improve team members' awareness of aspects that could be improved before training them in dealing with specific challenges.

The number of older homeless people with a limited life expectancy is increasing. European studies on their health‐related characteristics are lacking. This study compared self‐reported health, healthcare service use and health‐related needs of older and younger homeless people in the Netherlands. It is part of a cohort study that followed 513 homeless people in the four major Dutch cities for a period of 2.5 years, starting from the moment they registered at the social relief system in 2011. Using cross‐sectional data from 378 participants who completed 2.5‐year follow‐up, we analysed differences in self‐reported health, healthcare service use, and health‐related needs between homeless adults aged ≥50 years (N = 97) and <50 years (N = 281) by means of logistic regression. Results show that statistically significantly more older than younger homeless people reported cardiovascular diseases (23.7% versus 10.3%), visual problems (26.8% versus 14.6%), limited social support from family (33.0% versus 19.6%) and friends or acquaintances (27.8% versus 14.6%), and medical hospital care use in the past year (50.5% versus 34.5%). Older homeless people statistically significantly less often reported cannabis (12.4% versus 45.2%) and excessive alcohol (16.5% versus 27.0%) use in the past month and dental (20.6% versus 46.6%) and mental (16.5% versus 25.6%) healthcare use in the past year. In both age groups, few people reported unmet health‐related needs. In conclusion, compared to younger homeless adults, older homeless adults report fewer substance use problems, but a similar number of dental and mental problems, and more physical and social problems. The multiple health problems experienced by both age groups are not always expressed as needs or addressed by healthcare services. Older homeless people seem to use more medical hospital care and less non‐acute, preventive healthcare than younger homeless people. This vulnerable group might benefit from shelter‐based or community outreach programmes that proactively provide multidisciplinary healthcare services. [ABSTRACT FROM AUTHOR]

A literature review was carried out to identify pre and perinatal characteristics associated with variation in Apgar scores in population-based studies. The parameters identified in the literature search were included in the classical twin design study to estimate effects of pre and perinatal factors shared and nonshared by twins and to test for a contribution of genetic factors in 1- and 5-min Apgar scores in a large sample of Dutch monozygotic (MZ) and dizygotic (DZ) twins. The sample included MZ and DZ twins (N = 5181 pairs) recruited by the Netherlands Twin Register shortly after birth, with data on prenatal characteristics and Apgar scores at first and/or fifth minutes. The ordinal regression and structural equation modeling were used to analyze the effects of characteristics identified in the literature review and to estimate genetic and nongenetic variance components. The literature review identified 63 papers. Consistent with the review, we observed statistically significant effects of birth order, zygosity and gestational age (GA) for 1- and 5-min Apgar scores of both twins. Apgar scores are higher in first-born versus second-born twins and DZ first-born versus MZ first-born twins. Birth weight had an effect on the 5-min Apgar of the first born. Fetal presentation and mode of delivery had different effects on Apgar scores of first- and second-born twins. Parental characteristics and chorionicity did not have significant main effects on Apgar scores. The MZ twins' Apgar correlations equaled the DZ Apgar correlations. Our analyses suggest that individual differences in 1- and 5-min Apgar scores are attributable to shared and nonshared pre and perinatal factors, but not to genotypic factors of the newborns. The main predictors of Apgar scores are birth order, zygosity, GA, birth weight, mode of delivery and fetal presentation. [ABSTRACT FROM AUTHOR]

Purpose To describe short-term and long-term work status after a vocational rehabilitation (VR) program in patients with acquired brain injury (ABI) in the Netherlands. Methods Patients with ABI who participated in a VR program between 2007 and 2010 were included in this study. The 4-month VR program included a multidisciplinary assessment, three meetings with all stakeholders and reintegration with coaching on the job. Short-term results at the end of the VR program were based on data extracted from medical records. Long-term results were determined at 3-6 years (mean 4.4 years) after the program based on patient-reported data. Outcome measures included return to work, hours at work and task adjustments. Results Fifty-eight patients were included [mean age 48 (SD 9.4) years; n = 33 male; all working before ABI]. After the intervention, 50 patients (86%) had returned to work, working on average 60% of their former hours. Working tasks were adjusted in 48 patients. At long-term follow-up 28 patients had paid work, working on average 5.3 h more than immediately after the VR program. Conclusions Directly after the intervention 86% of the patients had returned to work. After 3-6 years, 64% of these patients were still working in a paid job. [ABSTRACT FROM AUTHOR]

Childhood aggression and its resulting consequences inflict a huge burden on affected children, their relatives, teachers, peers and society as a whole. Aggression during childhood rarely occurs in isolation and is correlated with other symptoms of childhood psychopathology. In this paper, we aim to describe and improve the understanding of the co-occurrence of aggression with other forms of childhood psychopathology. We focus on the co-occurrence of aggression and other childhood behavioural and emotional problems, including other externalising problems, attention problems and anxiety-depression. The data were brought together within the EU-ACTION (Aggression in Children: unravelling gene-environment interplay to inform Treatment and InterventiON strategies) project. We analysed the co-occurrence of aggression and other childhood behavioural and emotional problems as a function of the child’s age (ages 3 through 16 years), gender, the person rating the behaviour (father, mother or self) and assessment instrument. The data came from six large population-based European cohort studies from the Netherlands (2x), the UK, Finland and Sweden (2x). Multiple assessment instruments, including the Child Behaviour Checklist (CBCL), the Strengths and Difficulties Questionnaire (SDQ) and Multidimensional Peer Nomination Inventory (MPNI), were used. There was a good representation of boys and girls in each age category, with data for 30,523 3- to 4-year-olds (49.5% boys), 20,958 5- to 6-year-olds (49.6% boys), 18,291 7- to 8-year-olds (49.0% boys), 27,218 9- to 10-year-olds (49.4% boys), 18,543 12- to 13-year-olds (48.9% boys) and 10,088 15- to 16-year-olds (46.6% boys). We replicated the well-established gender differences in average aggression scores at most ages for parental ratings. The gender differences decreased with age and were not present for self-reports. Aggression co-occurred with the majority of other behavioural and social problems, from both externalising and internalising domains. At each age, the co-occurrence was particularly prevalent for aggression and oppositional and ADHD-related problems, with correlations of around 0.5 in general. Aggression also showed substantial associations with anxiety-depression and other internalizing symptoms (correlations around 0.4). Co-occurrence for self-reported problems was somewhat higher than for parental reports, but we found neither rater differences, nor differences across assessment instruments in co-occurrence patterns. There were large similarities in co-occurrence patterns across the different European countries. Finally, co-occurrence was generally stable across age and sex, and if any change was observed, it indicated stronger correlations when children grew older. We present an online tool to visualise these associations as a function of rater, gender, instrument and cohort. In addition, we present a description of the full EU-ACTION projects, its first results and the future perspectives. [ABSTRACT FROM AUTHOR]

Objective: In the Netherlands, various FFQs have been administered in large cohort studies, which hampers comparison and pooling of dietary data. The present study aimed to describe the development of a standardized Dutch FFQ, FFQ-NL1.0, and assess its compatibility with existing Dutch FFQs.Design: Dutch FFQTOOLTM was used to develop the FFQ-NL1.0 by selecting food items with the largest contributions to total intake and explained variance in intake of energy and thirty-nine nutrients in adults aged 25-69 years from the Dutch National Food Consumption Survey (DNFCS) 2007-2010. Compatibility with the Maastricht-FFQ, Wageningen-FFQ and EPICNL-FFQ was assessed by comparing the number of food items, the covered energy and nutrient intake, and the covered variance in intake.Results: FFQ-NL1.0 comprised 160 food items, v. 253, 183 and 154 food items for the Maastricht-FFQ, Wageningen-FFQ and EPICNL-FFQ, respectively. FFQ-NL1.0 covered ≥85 % of energy and all nutrients reported in the DNFCS. Covered variance in intake ranged from 57 to 99 % for energy and macronutrients, and from 45 to 93 % for micronutrients. Differences between FFQ-NL1.0 and the other FFQs in covered nutrient intake and covered variance in intake were <5 % for energy and all macronutrients. For micronutrients, differences between FFQ-NL and other FFQs in covered level of intake were <15 %, but differences in covered variance were much larger, the maximum difference being 36 %.Conclusions: The FFQ-NL1.0 was compatible with other FFQs regarding energy and macronutrient intake. However, compatibility for covered variance of intake was limited for some of the micronutrients. If implemented in existing cohorts, it is advised to administer the old and the new FFQ in combination to derive calibration factors. [ABSTRACT FROM AUTHOR]

Introduction: A home-based, low-intensity physical activity program (Onco-Move) and a supervised, moderate-to-high intensity, combined resistance and aerobic exercise program (OnTrack) have proven to be effective in maintaining physical fitness and reducing fatigue among breast cancer patients undergoing adjuvant chemotherapy. This study evaluated the cost-utility and cost-effectiveness of Onco-Move and OnTrack.Methods: A total of 230 patients were randomized to Onco-Move, OnTrack, or usual care (UC). Health outcomes included quality-adjusted life years (QALYs), general and physical fatigue, and physical fitness measured at baseline, end of chemotherapy, and 6-month follow-up. Societal costs included professional and informal health care, work absenteeism, and unpaid productivity costs. Cost data were based on 3-monthly questionnaires, supplemented by medication data obtained from pharmacies.Results: Onco-Move is not likely to be cost-effective due to the relatively high willingness-to-pay necessary to reach reasonable probabilities of cost-effectiveness (QALY, general and physical fatigue). Incremental cost-effectiveness ratios for OnTrack compared to UC were €26,916/QALY, €788/1-point decrease in general fatigue and €1402/1-point decrease in physical fatigue. The probability of OnTrack being cost-effective ranged from 31% at a willingness-to-pay (WTP) of €0-79% at a WTP of €80,000/QALY, 97% at a WTP of €15,000/1-point decrease in general fatigue, and 86% at a WTP of €24,000/1-point decrease in physical fatigue. Both interventions had a low probability of being cost-effective for physical fitness. The probability of cost-effectiveness for both interventions was greater among compliant participants.Conclusions: Onco-Move is not likely to be cost-effective. Depending on the decision-makers' willingness-to-pay, OnTrack could be considered cost-effective in comparison with UC.

Background: Several countries have changed, or are reevaluating, their blood donor policies for men who have had sex with men (MSM). Changing policies has consequences for donor recruitment and the donor pool. In this study, we investigated whether MSM are eligible and willing to donate blood.Study Design and Methods: Members of a research panel (n = 4422) in the Netherlands were invited to participate in an online survey. We asked questions about male-to-male sex and risk behavior that are also asked during the predonation screening of a blood donor. Furthermore, we asked questions about willingness to donate.Results: The total response rate was 60% (n = 2654). Of MSM nondonors (n = 230), 32.2% would be eligible to donate under a 12-month deferral policy, according to their reported risk history and last male-to-male sex. In other scenarios, 42.6% (4-month deferral), 38.7% (6-month deferral), and 18.7% (5-year deferral) would be eligible to donate. When not taking their last male-to-male sex into account (n = 203), 47.8% of MSM reported a moderate or high willingness to donate.Conclusion: A 12-month deferral after last male-to-male sex is a commonly used criterion by blood services. Approximately one-third of the MSM in our study would be eligible to donate under this deferral policy. Higher proportions of MSM would be eligible to donate in shorter deferral scenarios. Almost half of MSM are willing to donate blood. Targeting MSM by donor recruitment campaigns could therefore prove fruitful. [ABSTRACT FROM AUTHOR]

This article addresses the question whether maternal mortality should be excluded from the study o f excess female mortality. This phenomenon points to lower survival chances for women in certain a g e groups as opposed to men in the same a g e group. The existence o f excess female mortality has been established for a number o f European countries, primarily for the nineteenth century period, and it has also been observed for the Netherlands between approximately 18 5 0 and 19 3 0 . There are strong indications that in this period Dutch women were at a disadvantage compared to men, most notably between the ages o f 1 0 to 19 , but also in the adult years after a g e 20. The survival disadvanta g e for women between a g e 20 and 50 may be related to the dangers o f pregnancy and childbirth. These maternal mortality risks may seem a natural female disadvantage. However, deficiencies in nutrition may seriously enhance the dangers o f pregnancy and childbirth. The results o f our analysis indicate that maternal mortality in this period in the Netherlands is partly the effect o f the femalenutritional disease environment. In particular, the incidence o f nutrition-related deaths among women in fertile ages, such as t b , increase maternal mortality. We therefore assume that gen de r disadvantages in the access to foodstuffs o f sufficiënt nutritional quality increased the level o f maternal mortality. Consequently, in research on excess female mortality maternal mortality cannot be simply discounted as a natural disadvantage which should be left out o f measures o f excess female mortality.

Objective: To find out how the consumption of organic food during pregnancy is associated with consumer characteristics, dietary patterns and macro- and micronutrient intakes. Design: Cross-sectional description of consumer characteristics, dietary patterns and macro- and micronutrient intakes associated with consumption of organic food during pregnancy. Setting: Healthy, pregnant women recruited to a prospective cohort study at midwives' practices in the southern part of the Netherlands; to enrich the study with participants adhering to alternative lifestyles, pregnant women were recruited through various specific channels. Subjects: Participants who filled in questionnaires on food frequency in gestational week 34 (n 2786). Participant groups were defined based on the share of organic products within various food types. Results: Consumers of organic food more often adhere to specific lifestyle rules, such as vegetarianism or anthroposophy, than do participants who consume conventional food only (reference group). Consumption of organic food is associated with food patterns comprising more products of vegetable origin (soya/vegetarian products, vegetables, cereal products, bread, fruits, and legumes) and fewer animal products (milk and meat), sugar and potatoes than consumed in conventional diets. These differences translate into distinct intakes of macro- and micronutrients, including higher retinol, carotene, tocopherol and folate intakes, lower intakes of vitamin D and B12 and specific types of trans-fatty acids in the organic groups. These differences are seen even in groups with low consumption of organic food. Conclusions: Various consumer characteristics, specific dietary patterns and types of food intake are associated with the consumption of organic food during pregnancy. [ABSTRACT FROM AUTHOR]

Objective: To investigate the associations of organic food consumption with maternal pre-pregnancy BMI, hypertension and diabetes in pregnancy, and several blood biomarkers of pregnant women.Design: Prospective cohort study.Setting: Pregnant women were recruited at midwives' practices and through channels related to consumption of food from organic origin.Subjects: Pregnant women who filled in FFQ and donated a blood sample (n 1339). Participant groups were defined based on the share of consumed organic products; to discriminate between effects of food origin and food patterns, healthy diet indicators were considered in some statistical models.Results: Consumption of organic food was associated with a more favourable pre-pregnancy BMI and lower prevalence of gestational diabetes. Compared with participants consuming no organic food (reference group), a marker of dairy products intake (pentadecanoic acid) and trans-fatty acids from natural origin (vaccenic and rumenic acids) were higher among participants consuming organic food (organic groups), whereas elaidic acid, a marker of the intake of trans-fatty acids found in industrially hydrogenated fats, was lower. Plasma levels of homocysteine and 25-hydroxyvitamin D were lower in the organic groups than in the reference group. Differences in pentadecanoic acid, vaccenic acid and vitamin D retained statistical significance when correcting for indicators of the healthy diet pattern associated with the consumption of organic food.Conclusions: Consumption of organic food during pregnancy is associated with several health-related characteristics and blood biomarkers. Part of the observed associations is explained by food patterns accompanying the consumption of organic food. [ABSTRACT FROM AUTHOR]

Introduction: The use of improvised explosive devices is a frequent method of insurgents to inflict harm on deployed military personnel. Consequently, lower extremity injuries make up the majority of combat related trauma. The wounding pattern of an explosion is not often encountered in a civilian population and can lead to substantial disability. It is therefore important to study the impact of these lower extremity injuries and their treatment (limb salvage versus amputation) on functional outcome and quality of life.Patients and Methods: All Dutch repatriated service members receiving treatment for wounds on the lower extremity sustained in the Afghan theater between august 2005 and August 2014, were invited to participate in this observational cohort study. We conducted a survey regarding their physical and mental health using the Short Form health survey 36, EuroQoL 6 dimensions and Lower Extremity Functional Scale questionnaires. Results were collated in a specifically designed electronic database combined with epidemiology and hospital statistics gathered from the archive of the Central Military Hospital. Statistical analyses were performed to identify differences between combat and non-combat related injuries and between limb salvage treatment and amputation.Results: In comparison with non-battle injury patients, battle casualties were significantly younger of age, sustained more severe injuries, needed more frequent operations and clinical rehabilitation. Their long-term outcome scores in areas concerning well-being, social and cognitive functioning, were significantly lower. Regarding treatment, amputees experienced higher physical well-being and less pain compared to those treated with limb salvage surgery.Conclusion: Sustaining a combat injury to the lower extremity can lead to partial or permanent dysfunction. However, wounded service members, amputees included, are able to achieve high levels of activity and participation in society, proving a remarkable resilience. These long-term results demonstrate that amputation is not a failure for casualty and surgeon, and strengthen a life before limb (damage control surgery) mindset in the initial phase. For future research, we recommend the use of adequate coding and injury scoring systems to predict outcome and give insight in the attributes that are supportive for the resilience that is needed to cope with a serious battle injury.

Background: Mental disorders are associated with high costs for productivity loss, sickness absence and unemployment. A participatory supportive return to work (RTW) program was developed in order to improve RTW among workers without an employment contract, sick-listed due to a common mental disorder. The program contained a participatory approach, integrated care and direct placement in a competitive job. The aim of this study was to evaluate the cost-effectiveness and cost-utility of this new program, compared to usual care. In addition, its return on investment was evaluated.Methods: An economic evaluation was conducted alongside a 12-month randomized controlled trial. A total of 186 participants was randomly allocated to the new program (n = 94) or to usual care (n = 92). Effect measures were the duration until sustainable RTW in competitive employment and quality-adjusted life years (QALYs) gained. Costs included intervention costs, medical costs and absenteeism costs. Registered data of the Dutch Social Security Agency were used to assess the duration until sustainable RTW, intervention costs and absenteeism costs. QALYs and medical costs were assessed using three- or six-monthly questionnaires. Missing data were imputed using multiple imputations. Cost-effectiveness analysis and cost-utility analysis were conducted from the societal perspective. A return on investment analysis was conducted from the social insurer's perspective. Various sensitivity analyses were performed to assess the robustness of the results.Results: The new program had no significant effect on the duration until sustainable RTW and QALYs gained. Intervention costs and medical costs were significantly higher in the intervention group. From the societal perspective, the maximum probability of cost-effectiveness for duration until sustainable RTW was 0.64 at a willingness to pay of about €10 000/day, and 0.27 for QALYs gained, regardless of the willingness to pay. From the social insurer's perspective, the probability of financial return was 0.18.Conclusions: From the societal perspective, the new program was neither cost-effective in improving sustainable RTW nor in gaining QALYs. From the social insurer's perspective, the program did not result in a positive financial return. Therefore, the present study provided no evidence to support its implementation.Trial Registration: The trial was listed at the Dutch Trial Register (NTR) under NTR3563 on August 7, 2012.
