- Abstract
In een dichtbevolkt land als Nederland hebben landbouwers en natuurbeschermers het bij hun beleidsplannen en toekomstvisies over dezelfde schaarse hectaren. Al vanaf het midden van de vorige eeuw botste verdere modernisering van het landbouwbedrijf op de eveneens groeiende behoefte aan natuur, ook voor recreatie. In dit artikel wordt ingegaan op de historische achtergronden vóór 1960 van deze belangentegenstelling: de halve eeuw waarin landbouwers en natuurbeschermers meestal met de ruggen naar elkaar stonden.

Item does not contain fulltext BACKGROUND: The inflammatory bowel disease (IBD) disability index has recently been introduced to measure patients' physical, psychological, familial, and social limitations associated with IBD. We assessed factors related to self-reported disability and the relationship between disability and direct health care costs. METHODS: A large cohort of patients with Crohn's disease (CD) and ulcerative colitis (UC) was prospectively followed for 2 years by 3 monthly web-based questionnaires. At 2 years, patients completed the IBD disability index, with lower score indicating more disability. Linear regression analysis was used to examine the impact of demographics, clinical characteristics, and illness perceptions on self-reported disability. Trends in direct health care costs across the disability severity groups minimal, mild, moderate, and severe, were tested. RESULTS: A total of 554 patients with CD and 424 patients with UC completed the IBD disability index (response rate, 45%). Both clinical characteristics and illness perceptions significantly contributed to self-reported disability (45%-47%, P = 0.000 and 8%-12%, P = 0.000, respectively). Patients with CD scored lower on the self-reported IBD disability index than patients with UC (0.255 versus 3.890, P < 0.000), indicating more disability in patients with CD. Factors independently associated with higher self-reported disability rates were increased disease activity, illness identity (higher number of symptoms attributed to IBD), and stronger emotional response. Disease duration and disease phenotype were not associated with self-reported disability. Direct health care costs increased with the worsening of self-reported disability (P = 0.000). CONCLUSIONS: More disability was reported by patients with CD than by UC. Self-reported disability in IBD was mainly determined by clinical disease activity and illness perceptions but not by disease duration or disease phenotype.

Leenders, M., Buunk, A.P., Henkens, K., Leenders, M., Buunk, A.P., and Henkens, K.
- Abstract
In this study, the relationship was investigated between attachment avoidance and attachment anxiety on the one hand, and job search intention, job search self-efficacy, job search self-esteem, and job search attitude on the other hand. Our sample consisted of 180 employees from an international industrial organization in the Netherlands. Results showed that attachment avoidance had a larger impact on the job search process than attachment anxiety. More avoidantly attached people had lower job search intentions, lower job search self-efficacy, and more negative job search attitudes. Attachment avoidance had an effect on job search intentions through job search self-efficacy and job search attitude but not through job search self-esteem. Attachment anxiety had no effect on job search intention through job search self-efficacy, job search self-esteem, and job search attitude. Attachment style is discussed as individual characteristic that impacts the job search process.

- Abstract
Introduction Although resistance type exercise training (RT) effectively increases muscle mass and strength in older individuals, it remains unclear whether gains in muscle mass and strength are maintained without continued supervised training. We assessed the capacity of older individuals to maintain muscle mass and strength gains one year after partaking in a successful RT program. Methods Fifty-three healthy older adults performed a 24-wk supervised RT program. Upon the cessation of the training program, participants were not provided with any advice or incentives to continue exercise training. One year after completion of the training program, all participants were contacted and invited back to the laboratory to assess anthropometrics, body composition (DXA), quadriceps muscle cross-sectional area (CSA) (CT-scan), muscle strength (1RM knee extension/leg press), and muscle fiber characteristics (muscle biopsy). Following primary analyses on all participants that responded to the invitation (n = 35), participants were divided into two groups: individuals who had continued to perform exercise training on an individual basis (EXER group; n = 16) and individuals who had not continued to perform any regular exercise (STOP group; n = 19) after completing the RT program. Results The initial increases in quadriceps CSA (+506 ± 209 and +584 ± 287 mm2) and knee extension strength (+32 ± 12 vs +34 ± 10 kg) after the 24-wk RT program did not differ between the STOP and EXER group (all P > 0.05). One year after discontinuation of the RT program, participants had lost muscle mass (P < 0.01), with a greater decline in quadriceps CSA in the STOP vs EXER group (−579 ± 268 vs −309 ± 253 mm2, respectively; P < 0.05). Muscle strength had decreased significantly compared to values after completing the RT program (P < 0.01), with no differences observed between the STOP vs EXER group (knee extension: −21 ± 8 vs −18 ± 8 kg, respectively; P > 0.05), yet remained higher compared with val

Recent studies have shown that cancer risk related to overweight and obesity is mediated by time and might be better approximated by using life years lived with excess weight. In this study we aimed to assess the impact of overweight duration and intensity in older adults on the risk of developing different forms of cancer. Study participants from seven European and one US cohort study with two or more weight assessments during follow-up were included (n = 329,576). Trajectories of body mass index (BMI) across ages were estimated using a quadratic growth model; overweight duration (BMI = 25) and cumulative weighted overweight years were calculated. In multivariate Cox models and random effects analyses, a longer duration of overweight was significantly associated with the incidence of obesity-related cancer [overall hazard ratio (HR) per 10-year increment: 1.36; 95 % CI 1.12–1.60], but also increased the risk of postmenopausal breast and colorectal cancer. Additionally accounting for the degree of overweight further increased the risk of obesity-related cancer. Risks associated with a longer overweight duration were higher in men than in women and were attenuated by smoking. For postmenopausal breast cancer, increased risks were confined to women who never used hormone therapy. Overall, 8.4 % of all obesity-related cancers could be attributed to overweight at any age. These findings provide further insights into the role of overweight duration in the etiology of cancer and indicate that weight control is relevant at all ages. This knowledge is vital for the development of effective and targeted cancer prevention strategies. © 2016, Springer Science+Business Media Dordrecht.

Medicine (all) ,Smoking - cardiovascular mortality - stroke - Abstract
OBJECTIVE: To investigate the impact of smoking and smoking cessation on cardiovascular mortality, acute coronary events, and stroke events in people aged 60 and older, and to calculate and report risk advancement periods for cardiovascular mortality in addition to traditional epidemiological relative risk measures. DESIGN: Individual participant meta-analysis using data from 25 cohorts participating in the CHANCES consortium. Data were harmonised, analysed separately employing Cox proportional hazard regression models, and combined by meta-analysis. RESULTS: Overall, 503 905 participants aged 60 and older were included in this study, of whom 37 952 died from cardiovascular disease. Random effects meta-analysis of the association of smoking status with cardiovascular mortality yielded a summary hazard ratio of 2.07 (95% CI 1.82 to 2.36) for current smokers and 1.37 (1.25 to 1.49) for former smokers compared with never smokers. Corresponding summary estimates for risk advancement periods were 5.50 years (4.25 to 6.75) for current smokers and 2.16 years (1.38 to 2.39) for former smokers. The excess risk in smokers increased with cigarette consumption in a dose-response manner, and decreased continuously with time since smoking cessation in former smokers. Relative risk estimates for acute coronary events and for stroke events were somewhat lower than for cardiovascular mortality, but patterns were similar. CONCLUSIONS: Our study corroborates and expands evidence from previous studies in showing that smoking is a strong independent risk factor of cardiovascular events and mortality even at older age, advancing cardiovascular mortality by more than five years, and demonstrating that smoking cessation in these age groups is still beneficial in reducing the excess risk. © 2015 BMJ Publishing Group Ltd.

Tumours of the digestive tract Radboud Institute for Health Sciences [Radboudumc 14] - Abstract
Item does not contain fulltext Various treatments are available for the palliation of esophageal cancer, but the optimal therapeutic approach is unclear. This study aimed to assess the palliative treatment modalities used in patients with inoperable esophageal cancer and to identify factors associated with treatment decisions. A population-based, retrospective cohort study was conducted using data from the nationwide Netherlands Cancer Registry and medical records of seven participating hospitals. Patients diagnosed with stage III-IV inoperable esophageal or gastric cardia cancer in the central part of the Netherlands between 2001 and 2010 were included. Logistic regression analyses were performed to identify determinants of treatment choices. In total, 736 patients were initially treated with best supportive care (21%), stent placement (19%), chemotherapy (18%), external beam radiotherapy (EBRT) (16%), brachytherapy (6%), a combination of EBRT and brachytherapy (6%), a combination of chemotherapy and EBRT (5%) or another treatment (9%). The palliative approach varied for disease stage (P < 0.01) and hospital of diagnosis (P < 0.01). Independent factors affecting treatment decisions were age, degree of dysphagia, tumor histology, tumor localization, disease stage, and hospital of diagnosis. For example, patients diagnosed in one hospital were less likely to be treated with EBRT than with stent placement compared to patients in another hospital (odds ratio 0.20, 95% confidence interval 0.07-0.59). In conclusion, the initial palliative approach of patients with inoperable esophageal cancer varies widely and is not only associated with patient- and disease-related factors, but also with hospital of diagnosis. These findings suggest a lack of therapeutic guidance and highlight the need for more evidence on palliative care strategies for esophageal cancer.

- Abstract
Sjoerd heeft een geschiedenis van seksueel misbruik en fysiek geweld in de kindertijd. Hij heeft een jaar lang traumabehandelingen gehad bij verschillende therapeuten, onder andere met behulp van imaginaire exposure en EMDR. De behandelingen wilden niet lukken doordat Sjoerd ‘niet bij zijn emoties kwam’. Hij had tijdens de behandeling last van freeze-reacties waarin hij vast bleef zitten, net als tijdens de traumatische gebeurtenis zelf, waardoor de behandeling stagneerde. Hij wordt nu verwezen naar een gespecialiseerd centrum voor traumabehandeling waar, omdat de behandeling opnieuw dreigt te stagneren, gekozen wordt voor de inzet van een nieuwe EMDR-techniek: de ‘EMD-knaller!’.

The rise of Open Access (OA) and its Gold business model – based on Article Process Charges (APC’s) – led to a new phenomenon that might be potentially damaging for the development of OA and the quality of academic publications: the predatory publisher. These publishers do not list positive peer-reviews as a criteria for their publications, but the fact that the supply side (i.e. the author, his/her institution, or a funding body) has paid for it. By taking on everything or even actively sending spam mail to academics, offering a chance to publish with them, these publishers create misconceptions about OA and, more importantly, may even devalue OA publications. The problem with modern technology is that everyone can build a website and pretend to be an OA publisher, which makes it even easier for these predatory publishers. So how to restore this trust and make sure that all OA publications are of a certain quality? Who will check the authority of these publishers, and how? Who will step up and protect authors, but also the concept of OA, from falling into the hands of these predatory publishers whose only goal it is to make money? Big OA platforms such as OAPEN Library and DOAJ only accept material that has been peer-reviewed. Others, like Jeffrey Beall, have made a blacklist of all potentially damaging publishers. In the end, a growing awareness seems to be one of the most important features to tackle this problem that is harmful on various levels. This paper will dive into the results – both positive and negative – of predatory publishers.

- Abstract
Carotenoids and vitamins A, C and E are possibly associated with a reduced colorectal cancer (CRC) risk through antioxidative properties. The association of prediagnostic plasma concentrations and dietary consumption of carotenoids and vitamins A, C and E with the risk of colon and rectal cancer was examined in this case-control study, nested within the European Prospective Investigation into Cancer and Nutrition study. Plasma concentrations of carotenoids (α- and β-carotene, canthaxanthin, β-cryptoxanthin, lutein, lycopene, zeaxanthin) and vitamins A (retinol), C and E (α-, β- and γ- and δ-tocopherol) and dietary consumption of β-carotene and vitamins A, C and E were determined in 898 colon cancer cases, 501 rectal cancer cases and 1,399 matched controls. Multivariable conditional logistic regression models were performed to estimate incidence rate ratios (IRR) and corresponding 95% confidence intervals (CIs). An association was observed between higher prediagnostic plasma retinol concentration and a lower risk of colon cancer (IRR for highest quartile = 0.63, 95% CI: 0.46, 0.87, p for trend = 0.01), most notably proximal colon cancer (IRR for highest quartile = 0.46, 95% CI: 0.27, 0.77, p for trend = 0.01). Additionally, inverse associations for dietary β-carotene and dietary vitamins C and E with (distal) colon cancer were observed. Although other associations were suggested, there seems little evidence for a role of these selected compounds in preventing CRC through their antioxidative properties.

- Abstract
In this study, the relation between fruit and vegetable consumption and mortality was investigated within the European Prospective Investigation Into Cancer and Nutrition. Survival analyses were performed, including 451,151 participants from 10 European countries, recruited between 1992 and 2000 and followed until 2010. Hazard ratios, rate advancement periods, and preventable proportions to respectively compare risk of death between quartiles of consumption, to estimate the period by which the risk of death was postponed among high consumers, and to estimate proportions of deaths that could be prevented if all participants would shift their consumption 1 quartile upward. Consumption of fruits and vegetables was inversely associated with all-cause mortality (for the highest quartile, hazard ratio = 0.90, 95% confidence interval (CI): 0.86, 0.94), with a rate advancement period of 1.12 years (95% CI: 0.70, 1.54), and with a preventable proportion of 2.95%. This association was driven mainly by cardiovascular disease mortality (for the highest quartile, hazard ratio = 0.85, 95% CI: 0.77, 0.93). Stronger inverse associations were observed for participants with high alcohol consumption or high body mass index and suggested in smokers. Inverse associations were stronger for raw than for cooked vegetable consumption. These results support the evidence that fruit and vegetable consumption is associated with a lower risk of death.

Contains fulltext : 172504.PDF (Publisher’s version ) (Open Access) BACKGROUND: With the increasing use of anti-TNF therapy in inflammatory bowel disease (IBD), a shift of costs has been observed with medication costs replacing hospitalization and surgery as major cost driver. We aimed to explore the evolution of IBD-related costs over two years of follow-up. METHODS AND FINDINGS: In total 1,307 Crohn's disease (CD) patients and 915 ulcerative colitis (UC) patients were prospectively followed for two years by three-monthly web-based questionnaires. Changes of healthcare costs, productivity costs and out-of-pocket costs over time were assessed using mixed model analysis. Multivariable logistic regression analysis was used to identify costs drivers. In total 737 CD patients and 566 UC were included. Total costs were stable over two years of follow-up, with annual total costs of euro7,835 in CD and euro3,600 in UC. However, within healthcare costs, the proportion of anti-TNF therapy-related costs increased from 64% to 72% in CD (p

Flow cytometry (FC) is recognized as an important tool in the diagnosis of myelodysplastic syndromes (MDS) especially when standard criteria fail. A working group within the Dutch Society of Cytometry aimed to implement FC in the diagnostic work-up of MDS. Hereto, guidelines for data acquisition, analysis and interpretation were formulated. Based on discussions on analyses of list mode data files and fresh MDS bone marrow samples and recent literature, the guidelines were modified. Over the years (2005-2011), the concordance between the participating centers increased indicating that the proposed guidelines contributed to a more objective, standardized FC analysis, thereby ratifying the implementation of FC in MDS.

Rapid administration of stable iodine is essential for the saturation and subsequent protection of the thyroid gland against the potential harm caused by radioiodines. This paper proposes the Dutch risk analysis that uses an atmospheric dispersion model to calculate the size of the zones around nuclear power plants where radiological thyroid doses for children might be sufficiently high to warrant iodine administration. Dose calculations for possible releases from the nuclear power plants of Borssele (The Netherlands), Doel (Belgium) and Emsland (Germany) are based on two scenarios in combination with a 1-y set of authentic, high-resolution meteorological data. The dimensions of the circular zones were defined for each nuclear power plant. In these zones, with a radius up to 50 km, distribution of stable iodine tablets is advised.

- Abstract
Background: Dairy products may be involved in the etiology of inflammatory bowel disease by modulating gut microbiota and immune responses, but data from epidemiological studies examining this relationship are limited. We investigated the association between prediagnostic intake of these foods and dietary calcium, and the subsequent development of Crohn's disease (CD) and ulcerative colitis (UC). Methods: In total, 401,326 participants were enrolled in the European Prospective Investigation into Cancer and Nutrition cohort. At recruitment, consumption of total and specific dairy products (milk, yogurt, and cheese) and dietary calcium was measured using validated food frequency questionnaires. Cases developing incident CD (n 110) or UC (n 244) during follow-up were matched with 4 controls. Conditional logistic regression analyses were used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for total energy intake and smoking. Results: Compared with the lowest quartile, the ORs for the highest quartile of total dairy products and dietary calcium intake were 0.61 (95% CI, 0.32-1.19, p trend 0.19) and 0.63 (95% CI, 0.28-1.42, p trend 0.23) for CD, and 0.80 (95% CI, 0.50-1.30, p trend 0.40) and 0.81 (95% CI, 0.49-1.34, p trend 0.60) for UC, respectively. Compared with nonconsumers, individuals consuming milk had significantly reduced odds of CD (OR 0.30, 95% CI, 0.13-0.65) and nonsignificantly reduced odds of UC (OR 0.85, 95% CI, 0.49-1.47). Conclusions: Milk consumption may be associated with a decreased risk of developing CD, although a clear dose-response relationship was not established. Further studies are warranted to confirm this possible protective effect. © 2016 Crohn's & Colitis Foundation of America, Inc.

Previously, a lower risk of colorectal cancer was observed with fruit and vegetable consumption in the European Prospective Investigation into Cancer and Nutrition within a follow-up period of 9 years which was not fully supported by a recent meta-analysis. Therefore, we were interested in the relation with extended follow-up, also focusing on single subtypes and a variety of intake of fruit and vegetables. Fruit and vegetable consumption was assessed at baseline. After an average of 13 years of follow-up, 3,370 participants were diagnosed with colon or rectal cancer. Diet diversity scores were constructed to quantify variety in fruit and vegetable consumption. A lower risk of colon cancer was observed with higher self-reported consumption of fruit and vegetable combined (HR Q4 vs. Q1 0.87, 95% CI 0.75-1.01, p for trend 0.02), but no consistent association was observed for separate consumption of fruits and vegetables. No associations with risk of rectal cancer were observed. The few observed associations for some fruit and vegetable subtypes with colon cancer risk may have been due to chance. Variety in consumption of fruits and vegetables was not associated with a lower risk of colon or rectal cancer. Although a lower risk of colon cancer is suggested with high consumption of fruit and vegetables, this study does not support a clear inverse association between fruit and vegetable consumption and colon or rectal cancer beyond a follow-up of more than 10 years. Attenuation of the risk estimates from dietary changes over time cannot be excluded, but appears unlikely. What's new? Eating a healthy diet loaded with fruits and vegetables will help you stave off cancer - that's the conventional wisdom. But the relationship between diet and cancer is complex. This study probed the effects of fruits and vegetables on colorectal cancer risk. The authors combed through data from the European Prospective Investigation into Cancer and Nutrition (EPIC) and analyzed total fruit and vegetable consumption as well as individual subtypes. Contrary to earlier results, they found no correlation between fruit and vegetable intake and colorectal cancer risk over a period of more than ten years.

Background and Aims: More data are warranted on the economic impact of different treatment strategies in ulcerative colitis (UC) patients. We compared the costs and quality of life of UC patients with a pouch reconstruction, an ileostomy or anti-tumour necrosis factor alpha (TNF alpha) therapy.Methods: UC patients filled out 3-monthly questionnaires for 2 years. Differences in 3-monthly healthcare costs, productivity costs and patient costs were tested using mixed model analysis. Quality of life was assessed employing the) and the inflammatory bowel disease questionnaire (IBDQ).Results: Out of 915 UC patients, 81 (9%) had a pouch and 48 (5%) an ileostomy, and 34 (4%) were on anti-TNF alpha therapy. Anti-TNF alpha-treated patients reported high UC related-healthcare costs per 3 months ((sic)5350). Medication use accounted for 92% of healthcare costs. UC-attributable healthcare costs were 3-fold higher in ileostomy patients compared with pouch patients ((sic)1581 versus (sic)407; p Conclusion: Patients receiving anti-TNF alpha therapy reported the highest healthcare cost, in which medication use was the major cost driver. Ileostomy patients were three times more expensive than pouch patients due to frequent hospitalization and ileostomy supplies.

Consumption of fruits and vegetables was inversely associated with all-cause mortality (for the highest quartile, hazard ratio = 0.90, 95% confidence interval (CI): 0.86, 0.94), with a rate advancement period of 1.12 years (95% CI: 0.70, 1.54), and with a preventable proportion of 2.95%. This association was driven mainly by cardiovascular disease mortality (for the highest quartile, hazard ratio = 0.85, 95% CI: 0.77, 0.93). Stronger inverse associations were observed for participants with high alcohol consumption or high body mass index and suggested in smokers. Inverse associations were stronger for raw than for cooked vegetable consumption. These results support the evidence that fruit and vegetable consumption is associated with a lower risk of death. In this study, the relation between fruit and vegetable consumption and mortality was investigated within the European Prospective Investigation Into Cancer and Nutrition.

- Abstract
Item does not contain fulltext, OBJECTIVE: For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS. PATIENTS AND METHODS: This randomized multicenter trial included 219 patients who were randomized to receive plastic stent (n=73) or SEMS [uncovered (n=75) and covered (n=71); n=146] placement. HRQoL was assessed with two general questionnaires (EQ-5D-3L and QLQ-C30) and one disease-specific questionnaire (PAN-26). Scores were analyzed using linear mixed model regression and included all patients with baseline and at least one follow-up measurement. RESULTS: HRQoL data were available in 140 of 219 patients (64%); 71 patients (32%) declined participation and in eight patients (4%) only baseline questionnaires were available. On the QLQ-C30, the interaction between follow-up time and type of stent was significantly different on two of five functional scales [physical functioning (P=0.004) and emotional functioning (P=0.01)] in favor of patients with a SEMS. In addition, patients with SEMS reported significantly less frequent symptoms of fatigue (P=0.01), loss of appetite (P=0.02), and nausea and vomiting (0.04) over time. The EQ-VAS score decreased with time in both treatment groups, indicating a statistically significant decrease in HRQoL over time. CONCLUSION: In patients with inoperable malignant extrahepatic bile duct obstruction, SEMS placement results in better scores for general and disease-specific HRQoL over time compared with plastic stent placement.

- Abstract
Contains fulltext : 174836.pdf (Publisher’s version ) (Open Access), BACKGROUND: Most post-colonoscopy colorectal cancers (PC-CRCs) are thought to develop from missed or incompletely resected adenomas. AIMS: We aimed to assess the incidence rate of PC-CRC overall and per colorectal segment, as a proxy for PC-CRC due to incomplete adenoma resection, and to identify adenoma characteristics associated with these PC-CRCs. METHODS: We performed a nationwide, population-based cohort study, including all patients with a first colorectal adenoma between 2000-2010 in the Dutch Pathology Registry (PALGA). Outcomes were the incidence rate of PC-CRC overall and of PC-CRC in the same colorectal segment, occurring between six months and five years after adenoma resection. A multivariable Cox proportional hazard analysis was performed to identify factors associated with PC-CRCs in the same segment. RESULTS: We included 107,744 patients (mean age 63.4 years; 53.6% male). PC-CRC was detected in 1031 patients (0.96%) with an incidence rate of 1.88 per 1000 person years. PC-CRC in the same segment was found in 323 of 133,519 adenomas (0.24%) with an incidence rate of 0.56 per 1000 years of follow-up. High-grade dysplasia (hazard ratio (HR) 2.54, 95% confidence interval (CI) 1.99-3.25) and both villous (HR 2.63, 95% CI 1.79-3.87) and tubulovillous histology (HR 1.80, 95% CI 1.43-2.27) were risk factors for PC-CRC in the same segment. CONCLUSIONS: Approximately one-third of PC-CRCs are found in the same colorectal segment after adenoma resection and could therefore be a consequence of incomplete adenoma resection, occurring in one in 400 adenomas. The risk of PC-CRC in the same segment is increased in adenomas with high-grade dysplasia or (tubulo)villous histology.

- Abstract
Item does not contain fulltext, Background and aims In multiple endocrine neoplasia type 1 (MEN1), endoscopic ultrasound (EUS) is used for identification and follow-up of pancreatic neuroendocrine tumors (PNETs). The role of EUS in surveillance of small ( < 20 mm) PNETs is unclear, mostly because the natural course of these lesions is largely unknown. We aimed to determine annual growth and incidence rate of small PNETs in patients with MEN1 using EUS-based surveillance. Patients and methods Linear array EUS procedures in patients with MEN1 between 2002 and 2015 were identified. Number, size, and location of PNETs were recorded. Annual growth of PNETs < 20 mm identified at the initial EUS ("prevalent" PNETs) and during follow-up ("incident" PNETs) was calculated using mixed model linear regression analysis. Results A total of 54 patients were identified and 38 patients were included. In all, 226 PNETs were identified (median size 5.0 mm, interquartile range 3.7 - 7.5) of which 124 (55 %) were prevalent and 102 (45 %) were incident PNETs. Annual incidence rate was 0.79 PNETs/year (95 % confidence interval [CI] 0.73 to 0.87). Overall growth rate was 0.10 mm/year (95 %CI 0.02 to 0.19; P = 0.01); PNETs < 10 mm (n = 198) did not grow (P = 0.23), whereas PNETs >/= 10 mm (n = 28) grew 0.44 mm/year (95 %CI 0.10 to 0.78; P = 0.01). Prevalent PNETs grew 0.21 mm/year (95 %CI 0.10 - 0.32; P < 0.001), whereas incident PNETs did not grow (P = 0.26). Conclusions The annual growth rate of small, solid PNETs in patients with MEN1 is lower than previously thought. Surveillance intervals could probably be prolonged without compromising safety.

- Abstract
Item does not contain fulltext, Background: The relationship between coffee consumption and mortality in diverse European populations with variable coffee preparation methods is unclear. Objective: To examine whether coffee consumption is associated with all-cause and cause-specific mortality. Design: Prospective cohort study. Setting: 10 European countries. Participants: 521 330 persons enrolled in EPIC (European Prospective Investigation into Cancer and Nutrition). Measurements: Hazard ratios (HRs) and 95% CIs estimated using multivariable Cox proportional hazards models. The association of coffee consumption with serum biomarkers of liver function, inflammation, and metabolic health was evaluated in the EPIC Biomarkers subcohort (n = 14 800). Results: During a mean follow-up of 16.4 years, 41 693 deaths occurred. Compared with nonconsumers, participants in the highest quartile of coffee consumption had statistically significantly lower all-cause mortality (men: HR, 0.88 [95% CI, 0.82 to 0.95]; P for trend < 0.001; women: HR, 0.93 [CI, 0.87 to 0.98]; P for trend = 0.009). Inverse associations were also observed for digestive disease mortality for men (HR, 0.41 [CI, 0.32 to 0.54]; P for trend < 0.001) and women (HR, 0.60 [CI, 0.46 to 0.78]; P for trend < 0.001). Among women, there was a statistically significant inverse association of coffee drinking with circulatory disease mortality (HR, 0.78 [CI, 0.68 to 0.90]; P for trend < 0.001) and cerebrovascular disease mortality (HR, 0.70 [CI, 0.55 to 0.90]; P for trend = 0.002) and a positive association with ovarian cancer mortality (HR, 1.31 [CI, 1.07 to 1.61]; P for trend = 0.015). In the EPIC Biomarkers subcohort, higher coffee consumption was associated with lower serum alkaline phosphatase; alanine aminotransferase; aspartate aminotransferase; gamma-glutamyltransferase; and, in women, C-reactive protein, lipoprotein(a), and glycated hemoglobin levels.

Leenders, M. and Leenders, M.
- Abstract
In this dissertation in four studies psychological factors are investigated that may affect the development of careers of employees. On the one hand, it was found that experiences of people in early childhood might affect their career. People may differ in their attachment styles with the consequences that there are differences in their coping with daily challenges at work. Employees who have a more avoidant attachment style, for example, experience more problems with job search behaviour. On the other hand, results show that workers with a positive relationship with their parents at an early age have a more positive work orientation and a stronger work ethic later in life. Also personality may play a role. In one of the studies it turned out that employees who after a forced resignation had to apply for a new job exhibit more procrastination as they experienced less control over their life and were less motivated to achievement. Procrastination, however, did not affect the chance of finding another job. Finally, it appeared that a high workload, less challenge and a lack of social support may lead to burnout complaints among employees over fifty years of age. Employees with these complaints and moreover those with a good marital relationship wanted to retire earlier. The results of the different studies show that psychological mechanisms may play a role in dealing with the demands asked of people at work.

- Abstract
We examined the extent to which individual relationships with mother and father, social support from partner, and quality of the relationship with the partner, are related to work orientation and work ethic. Survey data were obtained from 3841 respondents from the Netherlands Kinship Panel Study (wave 2). The results showed that, overall, people with a more positive relationship with their parents had a more positive work orientation and a stronger work ethic. A positive relationship with the father had a greater influence on these work aspects than a positive relationship with the mother, particularly for men. Partner support and the quality of the partner relationship partially mediated the association between the relationship with one's parents and work orientation only for women. There were no significant relationships between partner support or the quality of the partner relationship, and work ethic. Research on the relationship with parents and work-related variables is discussed.

- Abstract
Fish is a source of important nutrients and may play a role in preventing heart diseases and other health outcomes. However, studies of overall mortality and cause-specific mortality related to fish consumption are inconclusive. We examined the rate of overall mortality, as well as mortality from ischaemic heart disease and cancer in relation to the intake of total fish, lean fish, and fatty fish in a large prospective cohort including ten European countries. More than 500,000 men and women completed a dietary questionnaire in 1992–1999 and were followed up for mortality until the end of 2010. 32,587 persons were reported dead since enrolment. Hazard ratios and their 99 % confidence interval were estimated using Cox proportional hazard regression models. Fish consumption was examined using quintiles based on reported consumption, using moderate fish consumption (third quintile) as reference, and as continuous variables, using increments of 10 g/day. All analyses were adjusted for possible confounders. No association was seen for fish consumption and overall or cause-specific mortality for both the categorical and the continuous analyses, but there seemed to be a U-shaped trend (p

Contains fulltext : 172504.PDF (publisher's version ) (Open Access), BACKGROUND: With the increasing use of anti-TNF therapy in inflammatory bowel disease (IBD), a shift of costs has been observed with medication costs replacing hospitalization and surgery as major cost driver. We aimed to explore the evolution of IBD-related costs over two years of follow-up. METHODS AND FINDINGS: In total 1,307 Crohn's disease (CD) patients and 915 ulcerative colitis (UC) patients were prospectively followed for two years by three-monthly web-based questionnaires. Changes of healthcare costs, productivity costs and out-of-pocket costs over time were assessed using mixed model analysis. Multivariable logistic regression analysis was used to identify costs drivers. In total 737 CD patients and 566 UC were included. Total costs were stable over two years of follow-up, with annual total costs of euro7,835 in CD and euro3,600 in UC. However, within healthcare costs, the proportion of anti-TNF therapy-related costs increased from 64% to 72% in CD (p<0.01) and from 31% to 39% in UC (p < 0.01). In contrast, the proportion of hospitalization costs decreased from 19% to 13% in CD (p<0.01), and 22% to 15% in UC (p < 0.01). Penetrating disease course predicted an increase of healthcare costs (adjusted odds ratio (adj. OR) 1.95 (95% CI 1.02-3.37) in CD and age <40 years in UC (adj. OR 4.72 (95% CI 1.61-13.86)). CONCLUSIONS: BD-related costs remained stable over two years. However, the proportion of anti-TNF-related healthcare costs increased, while hospitalization costs decreased. Factors associated with increased costs were penetrating disease course in CD and age <40 in UC.

- Abstract
Contains fulltext : 172523.pdf (Publisher’s version ) (Open Access), BACKGROUND: Industrialization has been linked to the etiology of inflammatory bowel disease (IBD). AIM: We investigated the association between air pollution exposure and IBD. METHODS: The European Prospective Investigation into Cancer and Nutrition cohort was used to identify cases with Crohn's disease (CD) (n = 38) and ulcerative colitis (UC) (n = 104) and controls (n = 568) from Denmark, France, the Netherlands, and the UK, matched for center, gender, age, and date of recruitment. Air pollution data were obtained from the European Study of Cohorts for Air Pollution Effects. Residential exposure was assessed with land-use regression models for particulate matter with diameters of <10 mum (PM10), <2.5 mum (PM2.5), and between 2.5 and 10 mum (PMcoarse), soot (PM2.5 absorbance), nitrogen oxides, and two traffic indicators. Conditional logistic regression analyses were performed to calculate odds ratios (ORs) with 95 % confidence intervals (CIs). RESULTS: Although air pollution was not significantly associated with CD or UC separately, the associations were mostly similar. Individuals with IBD were less likely to have higher exposure levels of PM2.5 and PM10, with ORs of 0.24 (95 % CI 0.07-0.81) per 5 mug/m(3) and 0.25 (95 % CI 0.08-0.78) per 10 mug/m(3), respectively. There was an inverse but nonsignificant association for PMcoarse. A higher nearby traffic load was positively associated with IBD [OR 1.60 (95 % CI 1.04-2.46) per 4,000,000 motor vehicles x m per day]. Other air pollutants were positively but not significantly associated with IBD. CONCLUSION: Exposure to air pollution was not found to be consistently associated with IBD.

- Abstract
Item does not contain fulltext, BACKGROUND: Dairy products may be involved in the etiology of inflammatory bowel disease by modulating gut microbiota and immune responses, but data from epidemiological studies examining this relationship are limited. We investigated the association between prediagnostic intake of these foods and dietary calcium, and the subsequent development of Crohn's disease (CD) and ulcerative colitis (UC). METHODS: In total, 401,326 participants were enrolled in the European Prospective Investigation into Cancer and Nutrition cohort. At recruitment, consumption of total and specific dairy products (milk, yogurt, and cheese) and dietary calcium was measured using validated food frequency questionnaires. Cases developing incident CD (n = 110) or UC (n = 244) during follow-up were matched with 4 controls. Conditional logistic regression analyses were used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for total energy intake and smoking. RESULTS: Compared with the lowest quartile, the ORs for the highest quartile of total dairy products and dietary calcium intake were 0.61 (95% CI, 0.32-1.19, p trend = 0.19) and 0.63 (95% CI, 0.28-1.42, p trend = 0.23) for CD, and 0.80 (95% CI, 0.50-1.30, p trend = 0.40) and 0.81 (95% CI, 0.49-1.34, p trend = 0.60) for UC, respectively. Compared with nonconsumers, individuals consuming milk had significantly reduced odds of CD (OR 0.30, 95% CI, 0.13-0.65) and nonsignificantly reduced odds of UC (OR 0.85, 95% CI, 0.49-1.47). CONCLUSIONS: Milk consumption may be associated with a decreased risk of developing CD, although a clear dose-response relationship was not established. Further studies are warranted to confirm this possible protective effect.
