Show moreUntil the 17th century, the Dutch coastal region of Zeeland ranked among Europe's most urbanized areas, driven by thriving international trade networks. People living in this time of flourishing economy benefitted enormously from it in terms of employment opportunities and working conditions, which were reportedly better than in the rest of the Low Countries. However, the rapid growth of Zeeland's urban centers likely presented increasing challenges for the population in terms of accessing essential resources, including food, clean water, and housing. In the 19th century, Zeeland's economy ultimately faced a significant downturn due to the decline in the maritime trade, leading to a substantial reduction in its urban population. Examining patterns of urbanization and economic histories that differ from the commonly studied thriving industrial contexts in bioarcheological research, as exemplified by Zeeland, is a crucial yet relatively underexplored facet in our efforts to understanding the human past. To address this gap, this study investigates the impact of urbanization on the health of Zeeland's inhabitants over time by analyzing nonspecific stress markers (i.e., cribra orbitalia, porotic hyperostosis, and linear enamel hypoplasia) and chronic maxillary sinusitis in a sample of 246 individuals from three urban sites dating from 1030 to 1800 CE. Our analysis of skeletal remains reveals significant differences in the prevalence of porotic hyperostosis, linear enamel hypoplasia, and sinusitis between the medieval and post-medieval periods. These findings suggest that de-urbanization and economic decline adversely affected the health and well-being of the populations under study, influenced by factors such as working conditions and food availability. This study provides a new perspective on bioarcheological approaches to urbanization, shedding light on the intricate realities of urbanization in Zeeland and offering important insights into its complexities.

Show moreTHIS PAPER ADDRESSES THE QUESTION, who were the people who were buried at the early medievalNorth Sea emporia? Conclusions about the mercantile character of the North Sea emporia are often based on portablematerial culture. In recognition of the fact that it is difficult to draw conclusions about the identities of people basedon finds assemblages, two pilot projects have been completed that involved bioarchaeological analyses of cemetery pop-ulations associated with these sites. The first of these, the Investigating the Dead in Early Medieval Domburg project,undertook multi-disciplinary analyses of the (very small) surviving burial population from the mostly destroyed sitesin the Domburg area (Netherlands), combining isotope analysis, radiocarbon dating, biological anthropology, dendro-chronology, and provenancing and study of previous use of coffin wood. The second, the Medieval Migrants of theNorth Sea World project, inventoried available isotopic evidence for human remains from emporia sites in England,the Netherlands and Scandinavia, alongside contextual archaeological information. This paper presents both projects,providing the detailed information from Domburg in its wider, international context, and highlighting the need for acomprehensive research agenda to fill current gaps in our understanding of early medieval emporia populations.

Show moreBackground:Identification of risk factors and causes of stroke is key to optimize treatment and prevent recurrence. Up to one-third of young patients with stroke have a cryptogenic stroke according to current classification systems (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] and atherosclerosis, small vessel disease, cardiac pathology, other causes, dissection [ASCOD]). The aim was to identify risk factors and leads for (new) causes of cryptogenic ischemic stroke in young adults, using the pediatric classification system from the IPSS study (International Pediatric Stroke Study).Methods:This is a multicenter prospective cohort study conducted in 17 hospitals in the Netherlands, consisting of 1322 patients aged 18 to 49 years with first-ever, imaging confirmed, ischemic stroke between 2013 and 2021. The main outcome was distribution of risk factors according to IPSS classification in patients with cryptogenic and noncryptogenic stroke according to the TOAST and ASCOD classification.Results:The median age was 44.2 years, and 697 (52.7%) were men. Of these 1322 patients, 333 (25.2%) had a cryptogenic stroke according to the TOAST classification. Additional classification using the ASCOD criteria reduced the number patients with cryptogenic stroke from 333 to 260 (19.7%). When risk factors according to the IPSS were taken into account, the number of patients with no potential cause or risk factor for stroke reduced to 10 (0.8%).Conclusions:Among young adults aged 18 to 49 years with a cryptogenic ischemic stroke according to the TOAST classification, risk factors for stroke are highly prevalent. Using a pediatric classification system provides new leads for the possible causes in cryptogenic stroke, and could potentially lead to more tailored treatment for young individuals with stroke.

Show moreIn this project we examine whether homicide ‘clusters together’ with other adverse health outcomes in the Netherlands, focusing on child mortality, suicide, sexual risk behavior, and substance abuse. We expect moderate-to-strong correlations between homicide and the other adverse health phenomena (hypothesis 1). Further, we expect that these correlations will be reduced when social disorganization is controlled for (hypothesis 2).The study used population-level data between the years 1996 and 2019, for each of the 40 local regions of the Netherlands. We applied a multilevel correlation procedure to evaluate correlations between homicide and the other adverse health outcomes. Correlations between homicide and the other adverse health outcomes were modest. That is, we found only limited evidence for clustering between homicide and the other adverse health outcomes. The patterns of clustering that did occur, suggested that social disorganization in the region promotes risk-taking behaviors in the population, which ultimately increases rates of homicide, abuse of illegal drugs and births to adolescent parents.Project materials, syntax and supplementary information can be found on the Open Science Framework at https://osf.io/jd5yu/.

Show moreOver the past ten years, seven Dutch Universities have built a sustainable exchange with seven institutes in Cuban healthcare. The exchange was initiated by the Leiden University Medical Centre and the University of Medical Sciences of Havana. Cooperation with Cuba was chosen as Cuba has excellent primary healthcare and has a strong focus on prevention and public health. These were considered important due to the major contribution of non-communicable diseases to morbidity and mortality in the Netherlands. Exchanges have occurred with Dutch health professionals and students visiting Cuban healthcare institutions and Cuban postgraduate students studying in the Netherlands. There has been an increased awareness of the importance of public health and prevention in Dutch professional organizations following the exchange. The exchange has also helped to break the scientific and economic US blockade of Cuba and resulted in joint publications. In this review we described the process, key aspects, results and lessons learned in this process. Collaboration between Cuba (a middle income) and the Netherlands (a high-income country) is possible. Show less

Show moreThe impact of COVID-19 on population health is recognised as being substantial, yet few studies have attempted to quantify to what extent infection causes mild or moderate symptoms only, requires hospital and/or ICU admission, results in prolonged and chronic illness, or leads to premature death. We aimed to quantify the total disease burden of acute COVID-19 in the Netherlands in 2020 using the disability-adjusted life-years (DALY) measure, and to investigate how burden varies between age-groups and occupations. Using standard methods and diverse data sources (mandatory notifications, population-level seroprevalence, hospital and ICU admissions, registered COVID-19 deaths, and the literature), we estimated years of life lost (YLL), years lived with disability, DALY and DALY per 100,000 population due to COVID-19, excluding post-acute sequelae, stratified by 5-year age-group and occupation category. The total disease burden due to acute COVID-19 was 286,100 (95% CI: 281,700-290,500) DALY, and the per-capita burden was 1640 (95% CI: 1620-1670) DALY/100,000, of which 99.4% consisted of YLL. The per-capita burden increased steeply with age, starting from 60 to 64 years, with relatively little burden estimated for persons under 50 years old. SARS-CoV-2 infection and associated premature mortality was responsible for a considerable direct health burden in the Netherlands, despite extensive public health measures. DALY were much higher than for other high-burden infectious diseases, but lower than estimated for coronary heart disease. These findings are valuable for informing public health decision-makers regarding the expected COVID-19 health burden among population subgroups, and the possible gains from targeted preventative interventions.

Show moreIntroduction: Epidemiological discrepancies exist between rare and common can-cers. The aim of this population-based study was to compare rare versus common adult solid cancers in the Netherlands, by providing incidence, prevalence and survival rates, evaluating trends in survival and comparing individual entities within domains and families.Methods: All adult patients with malignant solid cancers in the Netherlands between 1995 and 2019 were identified from the Netherlands Cancer Registry. Data on patient, tumour and treatment characteristics were collected, and relative survival and survival trends were ana-lysed.Results: A total of 170,628 patients with rare adult solid cancers and 806,023 patients with common adult solid cancers were included. Rare cancers accounted for 18% of all cancer di-agnoses (mean incidence), and 15% of the total ten-year cancer prevalence during 2010-2019. Overall 5-year survival was worse for rare cancers than for common cancers (52.0% versus 68.7%). Between 1995-1999 and 2015-2019, 5-year survival rates for rare cancers increased to a lesser extent (from 46.2% to 52.6%, i.e. 6.4%) than for common cancers (56.9% Show less

Show moreBackground and Purpose: Tumor recurrence, a characteristic of malignant tumors, is the biggest concern for rectal cancer survivors. The epidemiology of the disease calls for a pressing need to improve healthcare quality and patient outcomes. Prediction models such as Bayesian networks, which can probabilistically reason under uncertainty, could assist caregivers with patient management. However, some concerns are associated with the standard approaches to developing these structures in medicine. Therefore, this study aims to compare Bayesian network structures that stem from these two techniques. Materials and Methods: A retrospective analysis was performed on 6754 locally advanced rectal cancer (LARC) patients enrolled in 14 international clinical trials. Local tumor recurrence at 2, 3, and 5-years was defined as the endpoints of interest. Five rectal cancer treating physicians from three countries elicited the expert structure. The algorithmic structure was inferred from the data with the hill-climbing algorithm. Structural performance was assessed with calibration plots and area under the curve values. Results: The area under the curve for the expert structure on the training and validation data was above 0.9 and 0.8, respectively, for all the time points. However, the algorithmic structure had superior predictive performance over the expert structure for all time points of interest. Conclusion: We have developed and internally validated a Bayesian networks structure from experts' opinions, which can predict the risk of a LARC patient developing a tumor recurrence at 2, 3, and 5 years. Our result shows that the algorithmic-based structures are more performant and less interpretable than expert based structures. Show less

Show moreThis qualitative case study uses a life-course approach to explore syndemic vulnerability in a former fishing village in the Netherlands. Building on four years of fieldwork in a low-income neighborhood, we explored salient themes between and across families and generations. Elderly community members (> 65 years) were interviewed to map village history and explore how contextual factors have affected family life, health, and wellbeing since the 1940s. We systematically traced and compared processes leading to or from syndemic vulnerability by studying seven families across three generations. Adults with at least one of clustering diseases, their parents (when possible), and their children participated in semi-structured life-course interviews. A complex interaction of endemic social conditions, sociocultural normative processes, learned health be-haviors, and disheartening life events shaped families' predispositions for a syndemic of psychological distress, cardiometabolic conditions, and musculoskeletal pain. Educational attainment, continued social support, and aspirational capabilities emerged as themes related to decreasing syndemic vulnerability. This study demonstrates that syndemic vulnerability is potentially intergenerational and reveals the need for culturally sensitive and family-focused syndemic interventions. Future longitudinal research should focus on unravelling the pathogenesis of the clustering of psychological distress, cardiometabolic conditions, and musculoskeletal pain among young people.

Show moreCarbon Capture and Storage at industrial processes (industrial CCS) is expected to play an important role in reducing industrial CO2 emissions in the short term. Industrial CCS involves capturing CO2 from industrial processes, such as steel and cement making, and storing the CO2 underground. This study examined the public opinion of industrial CCS through an informed opinion survey in the Netherlands (N = 987) and the United Kingdom (UK; N = 974). On average, respondents were neutral to slightly positive about the implementation of industrial CCS in their country. UK respondents were slightly more positive (M = 4.66 on a 7-point scale) than Dutch respondents (M = 4.38). Awareness and perceived knowledge levels were somewhat higher in the Netherlands than in the UK. In both countries, perceived outcomes of industrial CCS (e.g. for climate change; safety; employment) were strongly associated with industrial CCS opinion, when compared to socio-demographics, proximity to industry (actual and perceived), and psychological variables. Differences between countries in outcome perceptions occur. For example, the safety of CO2 transport is a larger concern in the Netherlands than in the UK, while cost-control is a larger concern in the UK than in the Netherlands. These findings suggest that the national context for CCS implementation matters. Our research suggests that public engagement strategies will benefit from focusing on the economic and climate impacts of industrial CCS, as well as from building trust in industry and addressing perceived safety concerns surrounding different aspects of industrial CCS.

Show moreStudies of motivation in bilingual education settings often address questions of differences between learners in bilingual programmes and those in mainstream education. Problematic in this respect is our increasing awareness of the inherent differences between these two learner groups, as learners in bilingual programmes have often chosen or been selected for a bilingual route (Mearns et al., 2017). The study presented here therefore does not seek to compare learners in bilingual and non-bilingual programmes, but rather to explore the nature of language learning motivation within the context of bilingual secondary education (BSE) in the Netherlands. Using a purpose-designed tool reflecting the L2 Motivational Self System (Dörnyei, 2009), this study investigated trends in motivation across genders, academic tracks and year-groups of nearly 2000 learners. Findings suggest that, although these learners all have bilingual education in common, differences between the motivations of these groups should not be overlooked. Show less

Show moreBackground: Many countries organize population-based cervical cancer screening programs (CSP). In the Netherlands, eligible women are invited by mail. Marginalized women living in unstable conditions and homeless women often fail to receive the invitation letter. These women also experience access barriers to regular healthcare. Consequently, despite presumably being at higher risk of developing cervical cancer due to prevalent risk factors, marginalized women are rarely screened for cervical cancer. The aim of the study was to identify the prevalence of (pre)cancerous abnormalities among marginalized women, and subsequently explore invitation approaches to enhance their screening participation.Methods: A cross-sectional intervention study was conducted in Rotterdam, the Netherlands. Between February and May 2019, marginalized women aged 20-60 years were invited to participate in cervical screening. A participant was considered screen-positive when they tested positive for high-risk human papilloma virus (HR-HPV) and showed cytological abnormalities. Data of the study population were compared with regional data of the Dutch CSP. Various invitation approaches were used to recruit women.Results: Out of 74 included women, 12 participants (16%) were found screen-positive, against 3.4% in women screened by the Dutch CSP. The prevalence ratio for the study population was 4.4 (95% CI 1.9-8.6) compared with women screened by the Dutch CSP. Using a direct, pro-active approach resulted in participation of 92% of the included women.Conclusion: Marginalized women have an increased risk of (pre)cancerous cervical abnormalities in screening, compared with women screened by the Dutch CSP. A direct pro-active approach was the most effective to stimulate screening participation. Enhancement of screening uptake for this population needs special effort. Show less

Show moreIn recent years there has been growing attention for so-called crimmigration prisons: all-foreign prisons with immigration staff embedded where not rehabilitation, but deportation is the ultimate aim. Following Norway and the United Kingdom, since 2014 the Netherlands is another country with such a prison. This article analyses penal policies in the Netherlands vis-à-vis foreign national prisoners, including the establishment of the crimmigration prison. Drawing on extensive empirical fieldwork in the crimmigration prison, it subsequently examines how this is experienced and understood by both prison officers and foreign national officers. The results show that the limited opportunities to work on rehabilitation means that prison officers struggle to find meaning and satisfaction in their work. For prisoners, experiences in the crimmigration prison strongly depend on their subjective identity and attachment to the Netherlands. Whereas the lack of meaningful activities and remote location of the prison considerably add to the pains they experience, specific elements of the prison also help to mitigate some of the pains foreign national prisoners most commonly experience, especially isolation and uncertainty. The article finishes by a discussion about what this says about how the state should treat individuals it seeks to both punish and deport. Show less

Show moreIntroduction: The revised Dutch colorectal cancer guideline (2014), led to an overall decrease in preoperative radiotherapy (RT) use. This study evaluates hospital variation in RT use for resectable rectal cancer and the influence of guideline revision, including the nationwide impact of changing RT application on short term outcomes.Methods: Data of surgically resected rectal cancer patients registered in the Dutch ColoRectal Audit were extracted between 2011 and 2017. Patients were divided into groups based on time of guideline revision (<2014 and >= 2014). Primary outcome was guideline adherence at hospital level regarding RT application, stratified for three stage groups. Secondary outcomes included positive circumferential resection (CRM+) and 30-day complicated postoperative course.Results: The groups consisted of 7364 and 12,057 patients, respectively. In total, 6772 patients did not receive RT (17.6% (<2014) vs. 45.7% (>= 2014), p < 0.001). The largest increase of surgery alone was observed for cT1-2N0 stage rectal cancer (35.1% vs. 91.8%, p < 0.001), with a substantial decrease in hospital variation (IQR 22.2-50.0% vs. IQR 87.6-98.0%). For cT1-3N1MRF-stage rectal cancer, a substantial amount of hospital variation in short course RT remained after guideline revision (IQR 26.8-54.1% vs. IQR 26.2-50.0%). A significant decrease in CRMthorn (5.8% vs. 4.2%, p < 0.001) and complicated course (22.5% vs. 18.5%, p < 0.001) was observed.Conclusions: Radiotherapy for early-stage rectal cancer was uniformly abandoned after guideline revision, while substantial hospital variation remained for intermediate risk resectable rectal cancer in the Netherlands. The substantial nationwide decrease in the use of RT for rectal cancer treatment did not negatively impact CRM involvement.

Show moreBackground Current studies mainly focus on total weight loss and comorbidity reduction. Only a few studies compare Quality of Life (QoL) after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). This study was conducted to examine the extent of improvement in QoL on different domains after primary bariatric surgery and compare these results to Dutch reference values. Methods The study included prospectively collected data from patients who underwent primary bariatric surgery in five Dutch hospitals. The RAND-36 questionnaire was used to measure the patient's QoL; preoperatively and twelve months postoperatively. Postoperative scores were compared to Dutch reference values, standardized for age, using t-test. A difference of more than 5% was considered a minimal important difference. A multivariate linear regression analysis was used to compare SG and RYGB on the extent of improvement, adjusted for case-mix factors. Results In total, 4864 patients completed both the pre- and postoperative questionnaire. Compared with Dutch reference values, patients postoperatively reported clinically relevant better physical functioning (RYGB + 6.8%), physical role limitations (SG + 5.6%; RYGB + 6.2%) and health change (SG + 77.1%; RYGB + 80.0%), but worse general health perception (SG - 22.8%; RYGB - 17.0%). Improvement in QoL was similar between SG and RYGB, except for physical functioning (beta 2.758; p-value 0.008) and general health perception (beta 2.607; p-value < 0.001) for which RYGB patients improved more. Conclusions SG and RYGB patients achieved a better postoperative score in physical functioning, physical role limitations and health change compared to Dutch reference values, and a worse score in general health perception.

Show moreThis paper examines the productive role of secrecy in the nexus of transnational mobility, kinship, and intimate relations among Ghanaian-Dutch and Somali-Dutch in the Netherlands. Whereas secrecy is typically understood as one person concealing knowledge from another, implying the latter’s passivity, we argue that secrecy depends on mutually constitutive interactions. Secrecy is explored as the result of an interaction between those who obscure knowledge in creative ways and those who maintain a not-knowing. The paper analyzes how people negotiate moral expectations regarding sexuality, respect, and loyalty, while also manoeuvring to fulfil their personal aspirations. Especially in kinship relations, when people are bound to each other by moral and social obligations, the management of secrecy often makes people mutually dependent. Secrecy is revealed as skillfully choreographing relations by the ebb and flow of information where kinship, respect, or love and (not-) knowing reinforce another. Show less
