Show moreThis thesis has found a balance between individual data protection rights and the free flow of data. On the one hand, this balance serves to protect the individual and his data. On the other hand, health care and health research must take place using personal data.A balanced approach can be found in the following four ways. Firstly, a broad(-er) interpretation of the lawful basis of consent can facilitate secondary health research. Secondly, the use of other lawful bases can be a solution for the legitimation of secondary health research. Furthermore, a separate legal ground for secondary research can be a solution to resolve the issue of a lawful basis for health research.Thirdly, a balance can be found in the individual’s autonomy vis-à-vis the accountability of the health institution and the attention drawn to the free flow of data. The focus is shifted from the individual’s control over his data towards the health institution with other lawful bases than consent and a fair balance between data protection rights and the free flow of data.Fourthly, a risk-based approach to monitoring compliance contributes to balancing the rights and interests of individuals with data sharing for health care and research.

Show moreDit onderzoek richt zich op steunverlenende overheden die in het kader van het EU-staatssteunrecht algemene belangenafwegingen verrichten. In de verbodsfase van staatssteun moeten overheden beoordelen of een steunmaatregel (zoals een subsidie) als staatssteun kwalificeert. De weging van het algemene belang van staatssteun (bijvoorbeeld milieubescherming of cultuur) is gereserveerd voor de verenigbaarheidsfase. Bij de staatssteunhandhaving betrekt de Unie in toenemende mate nationale actoren (overheden en rechters) bij de beoordeling van deze algemene belangen, zowel in de verbodsfase als in de verenigbaarheidsfase. Dit proefschrift onderzoekt de algemene belangenafwegingen die ongelijke behandeling van ondernemingen rechtvaardigen, diensten van algemeen economisch belang uitzonderen en expliciet erkende sportbelangen een voorkeursbehandeling geven. Aansluitend wordt de beleidsruimte ter toetsing van groepsvrijstellingen aan verenigbaarheidscriteria door nationale actoren geanalyseerd. Daartoe worden een aantal knelpunten geïdentificeerd. Allereerst leiden de belangenafwegingen tot een vervaging van het onderscheid tussen de verbodstoepassing en de verenigbaarheidstoepassing. Zij raken daarmee aan de bevoegdheidsverdeling tussen nationale actoren en de Europese Commissie. Voorts mist het rechtmatigheidskader voor ex ante belangenafwegingen rechts zekerheid en ontbeert de ex post rechtmatigheidscontrole hierop een doeltreffende rechtsbeschermingsfunctie. Ter versterking van een gedecentraliseerde handhaving en een doeltreffende rechtsbescherming biedt dit onderzoek aanbevelingen op grond waarvan de Commissie verdere (afgebakende) bevoegdheden aan nationale actoren kan toestaan.

Show moreProteinuria is an independent risk factor for the progression of kidney injury, cardiovascular morbidity, and overall mortality. In this thesis, the pathways leading to proteinuria are explored by revisiting elements previously considered essential, investigating known pathways, and identifying new players in the field of proteinuria. First, a zebrafish embryo model for developing new therapeutic options for the rare but devastating disease of nephropathic cystinosis is presented. The studies presented in thesis also investigate loss of heparan sulphate glycosaminoglycans in a zebrafish embryo model and in multiple osteochondroma patients. These studies show that loss of heparan sulphate glycosaminoglycans does not always lead to proteinuria. Next, dynamin is described as a promising potential therapeutic target for treating proteinuria. The final study introduces transmembrane protein 14A as an essential factor in maintaining glomerular filtration barrier function. Overall, these studies contribute to elucidating the pathways to proteinuria in the hope to keep advancing the field towards targeted treatment of proteinuria for the benefit of our patients.

Show moreThe aim of the thesis was to contribute to a better understanding of the influence of differences in implant design and surgical techniques on the migration of total knee arthroplasties (TKAs) and, more broadly, the effect of using Radiostereometric Analysis (RSA) and other markers to detect early loosening. In this thesis, we compared various types of TKAs in different randomized controlled trials. Additionally, we investigated whether the positioning of TKAs relative to the patient's specific leg axis (e.g., neutral, varus, or valgus alignment) affects the stability of the prosthesis. We also analyzed, by combining registry data with data from a meta-analysis, whether TKAs evaluated with migration analysis (radiostereometric analysis; RSA) yield better results than TKAs that have not been previously examined with RSA. Finally, we conducted a systematic review to explore whether there are markers that can indicate loosening/failure of a prosthesis. Show less

Show moreAs fossil fuels are phased out in favour of renewable energy, electric cars and other low-carbon technologies, the future clean energy system is likely to require less overall mining than the current fossil-fuelled system. However, material extraction and waste flows, new infrastructure development, land-use change, and the provision of new types of goods and services associated with decarbonization will produce social and environmental pressures at localized to regional scales. Demand-side solutions can achieve the important outcome of reducing both the scale of the climate challenge and material resource requirements. Interdisciplinary systems modelling and analysis are needed to identify opportunities and trade-offs for demand-led mitigation strategies that explicitly consider planetary boundaries associated with Earth’s material resources.

Show moreThe subjective experience of financial stress has profound implications for well-being, health, cognitive performance, and decision-making. In a sample of Dutch households (N = 1114), we studied the association of five economic factors - income, saving, debts, income volatility, and employment - with a four-factor measure of financial stress: 1) an appraisal of insufficient financial resources, 2) an appraisal of lack of control over one's financial situation, 3) financial worries and rumination, and 4) a short-term focus. This enabled us to examine the economic factors' relative contributions to predicting5 financial stress. We found that the combination of economic factors predicted financial stress better than income alone. Particularly, buffer savings had a large contribution to predicting financial stress. The number of debts had a smaller relative contribution to predicting financial stress, whereas we did not find support for debt amount as a predictor of financial stress. Employment was negatively associated with financial stress, but only for households with the lowest incomes. We found no support for income volatility predicting financial stress. These results imply that research and policy on financial stress should have a broader scope than income alone and should take a more integrative approach to households' financial situation, considering savings, number of debts, and unemployment.

Show moreBackground: Measures against COVID-19 in nursing homes affected not only clients but also staff. However, staff perspectives on the importance of these measures remain underexplored. Objective: To investigate measures related to staff during the COVID-19 pandemic, staff perspectives of important measures and the involvement of staff in deciding on these measures. Design: A qualitative study. Setting(s): We analysed minutes of nursing home outbreak teams in the Netherlands and conducted group meetings with Dutch nursing home staff in different positions, prioritizing measures and discussing staff' involvement in deciding on the measures. Participants were recruited purposefully. Participants: The minutes of 41 nursing home organizations were collected during March-November, 2020. Four group meetings were organized in the same period, each with 5 to 7 participants, resulting in 23 participants. Methods: The meeting minutes were analysed using qualitative content analysis, whereas reflexive thematic analysis was used for the group meeting data. The group meetings were conducted online and structured by the Nominal Group Technique to discuss the importance of measures for staff. Results: Measures implemented for staff focused on prevention of COVID-19 transmission, (suspension of) educational activities, testing, additional tasks and staffing capacity, promoting wellbeing, and other means of support. The implemented measures overlapped with the measures considered important by staff. In addition, staff considered measures on decision-making support and communication to be important. Staff prioritized the measures in the group meetings because they affected their well-being, workforce scheduling, decision-making, or infection prevention. Furthermore, the group meetings revealed that decision-making shifted from mainly implementing national measures to more context-adjusted decision-making in the staff's or clients' situations. Conclusions: We showed that although nursing home staff were not always involved in decisionmaking during the first COVID-19 wave, there was overlap between the measures implemented by the organizations and measures considered important by staff. We suggest that organizations Show less

Show moreNanoplastics can cause severe malformations in chicken embryos. To improve our understanding of the toxicity of nanoplastics to embryos, we have studied their biodistribution in living chicken embryos. We injected the embryos in the vitelline vein at stages 18–19. We injected polystyrene nanoparticles (PS-NPs) tagged with europium- or fluorescence. Their biodistribution was tracked using inductively-coupled plasma mass spectrometry on tissue lysates, paraffin histology, and vibratome sections analysed by machine learning algorithms. PS-NPs were found at high levels in the heart, liver and kidneys. Furthermore, PS-NPs crossed the endocardium of the heart at sites of epithelial-mesenchymal transformation; they also crossed the liver endothelium. Finally, we detected PS-NPs in the allantoic fluid, consistent with their being excreted by the kidneys. Our study shows the power of the chicken embryo model for analysing the biodistribution of nanoplastics in embryos. Such experiments are difficult or impossible in mammalian embryos. These findings are a major advance in our understanding of the biodistribution and tissue-specific accumulation of PS-NPs in developing animals. Show less

Show moreThis article studies the use of the Bare Aorist in the Berber variety of Figuig, an oasis at the border of Morocco and Algeria. Like elsewhere in Berber, the Bare Aorist isused as a form that is neutral as to aspect, whose interpretation is provided by context. It is shown that the major types of occurrence that were established for other varieties (Mauri2017) are also represented in Figuig Bare Aorists. Framed Aorists are found in main clauses that are preceded by a temporal/aspectual clause that provides the framing for its aspectual interpretation. With Chained Aorists, the framing is provided by verbs in preceding main clauses. It is shown, however, that Chained Aorists are subtly different in Figuig from the way they have been described for other varieties, as they mainly occur to express continuity at points where such a continuity is less expected.

Show moreBackgroundWhen research evidence is limited, inconsistent, or absent, healthcare decisions and policies need to be based on consensus among interested stakeholders. In these processes, the knowledge, experience, and expertise of health professionals, researchers, policymakers, and the public are systematically collected and synthesised to reach agreed clinical recommendations and/or priorities. However, despite the influence of consensus exercises, the methods used to achieve agreement are often poorly reported. The ACCORD (ACcurate COnsensus Reporting Document) guideline was developed to help report any consensus methods used in biomedical research, regardless of the health field, techniques used, or application. This explanatory document facilitates the use of the ACCORD checklist.Methods and findingsThis paper was built collaboratively based on classic and contemporary literature on consensus methods and publications reporting their use. For each ACCORD checklist item, this explanation and elaboration document unpacks the pieces of information that should be reported and provides a rationale on why it is essential to describe them in detail. Furthermore, this document offers a glossary of terms used in consensus exercises to clarify the meaning of common terms used across consensus methods, to promote uniformity, and to support understanding for consumers who read consensus statements, position statements, or clinical practice guidelines (CPGs). The items are followed by examples of reporting items from the ACCORD guideline, in text, tables, and figures.ConclusionsThe ACCORD materials—including the reporting guideline and this explanation and elaboration document—can be used by anyone reporting a consensus exercise used in the context of health research. As a reporting guideline, ACCORD helps researchers to be transparent about the materials, resources (both human and financial), and procedures used in their investigations so readers can judge the trustworthiness and applicability of their results/recommendations.

Show moreThis contribution describes societies and institutes in the Netherlands that played key roles in scholarly research on the Ancient Near East and Egypt. Public interest followed academic developments at a distance. Leading figures, almost all academics, are briefly discussed.After a promising start in the 19th century, development in Dutch Egyptology was mostly limited to religious studies. Assyriology was largely a side-interest for theologians. While other European countries founded national scholarly societies and financed grand expeditions, attention in the Netherland was mainly directed to the Dutch East-Indies, with Oriental studies mostly a function of colonial administration, in combination with Semitic languages (connected to Bible studies).During the first quarter of the 20th century, Oriental studies in the Netherlands were marked by proliferation and specialisation – albeit with a continued emphasis on language studies, and usually from a biblical perspective. The general public was not yet involved. The second quarter of the 20th century saw further diversification of the field, a failed marriage between Ancient Near Eastern and Classical studies, and a broadening audience.After World War II, the range of history, language studies, and archaeology fully developed in the Netherlands. Internationalisation, rising population and student numbers, and economic growth were instrumental. The fourth quarter of the 20th century was characterised by the definitive division between Middle and Far Eastern versus Ancient Near Eastern studies. State-funded research was the norm; the popular audience increased.In the first quarter of the 21st century (not comprehensively addressed in this contribution) state-funded research declined while modest private initiatives (societies of museum and excavation “friends”) can be observed.

Show moreBackground: The risk of urinary tract infections (UTIs) is increased by unnecessary placement and prolonged use of urinary catheters. Aim: To assess whether inappropriate use of catheters and catheter-associated UTI were reduced through patient participation. Methods: In this multicentre, interrupted time-series and before-and-after study, we implemented a patient-centred app which provides catheter advice for patients, together with clinical lessons, feedback via e-mails and support rounds for staff members. Data on catheter use and infections were collected during a six-month baseline and a six-month intervention period on 13 wards in four hospitals in the Netherlands. Dutch Trial Register: NL7178. Findings: Between June 25th, 2018 and August 1st, 2019, 6556 patients were included in 24 point-prevalence surveys, 3285 (50%) at baseline and 3271 (50%) during the intervention. During the intervention 249 app users and a median of seven new app users per week were registered (interquartile range: 5.5e13.0). At baseline, inappropriate catheter use was registered for 175 (21.9%) out of 798 catheters, compared to 55 (7.0%) out of 786 during the intervention. Time-series analysis showed a non-significant decrease of inappropriate use of 5.8% (95% confidence interval: e3.76 to 15.45; P ¼ 0.219), with an odds ratio of 0.27 (0.19e0.37; P < 0.001). Catheter-associated UTI decreased by 3.0% (1.3e4.6; P ¼ 0.001), with odds ratio 0.541 (0.408e0.716; P < 0.001). Show less

Show morePredicting the development of rheumatoid arthritis (RA) in an early stage through magnetic resonance imaging (MRI) can initiate timely treatment and improve long-term patient outcomes. Although manual prediction is time-consuming and requires expert knowledge, automatic RA prediction has not been fully investigated. While standard models fail to achieve acceptable performance, we present a consistency-based deep learning framework to classify and predict RA automatically and precisely, including an output-standardized model, customized self-supervised pretraining and a loss function that is based on label consistency between original and augmented inputs. For training and evaluation, we used a database, containing 5945 MRI scans of carpal, metacarpophalangeal (MCP), and metatarsophalangeal (MTP) joints, from 2151 subjects obtained over a period of ten years. Four (three classification- and one prediction-) tasks were defined to distinguish two patient groups (with recent-onset arthritis and clinically suspect arthralgia) from healthy controls and RA from other arthritis patients within the recent-onset arthritis group, and predict RA development in a period of two years within the clinically suspect arthralgia group. The proposed method was evaluated with the area under the receiver operating curve (AUROC) on a separate test set, achieving mean AUROCs of 83.6%, 83.3%, and 69.7% in the three classification tasks, and 67.8% in the prediction task. This proves the existence of early signs of RA in MRI and the potential of a consistency-based deep learning model to detect these early signs and predict RA Show less

Show moreThis book focuses on the general right of suspension regulated in article 6:52 et seq. of the Dutch Civil Code. The author pays attention, among other things, to the requirements for the power to suspend, including the coherence criterion (Dutch: samenhangcriterium), which is also the central requirement. The author explains that this criterion is not a measure of judgment or criterion to be judged by itself, but the existence of sufficient coherence between mutual obligations to justify suspension is rather a conclusion that follows the application of the coherence criterion. The author also discusses how the general right of suspension is exercised. Under circumstances, that exercise may be unacceptable. This involves weighing the interests involved in that exercise. Procedural aspects of the general right of suspension are also discussed, including the dictum. The author discusses that under circumstances an order for gradual performance fits a defense of suspension better than a rejection of the claim. The author makes this concrete using many examples mainly from case law. This book is therefore relevant for both law and legal practice. Show less
