    Title translation Our new donation law: more autonomy?
    Abstract On 1 July 2020, the registration of organ and tissue donors in the Netherlands changed from an opt-in to an opt-out system. This means that everyone in the Netherlands will be registered as an organ and tissue donor unless they have registered a different choice in the donor register. The hope is that this new method for donor registration will lead to more donors. Only a small majority of members of the Senate and the House of Representatives in the Netherlands voted for the legislative amendment that enabled this new system to come into effect. In the Senate the amendment was defended on the grounds that it would do more justice to the autonomy of the deceased; the new law will, however, have to be defended from the principles of justice and solidarity by a government that feels responsibility towards those needing a donor organ.

    Abstract Resting state networks (RSN), which show the connectivity in the brain in the absence of any stimuli, are increasingly important to assess brain function. Here, we investigate the changes in RSN as well as the hemodynamic changes during acute, global hypoxia. Mice were imaged at different levels of oxygen (21, 12, 10 and 8%) over the course of 10 weeks, with hypoxia and normoxia acquisitions interspersed. Simultaneous GCaMP and intrinsic optical imaging allowed tracking of both neuronal and hemodynamic changes. During hypoxic conditions, we found a global increase of both HbO and HbR in the brain. The saturation levels of blood dropped after the onset of hypoxia, but surprisingly climbed back to levels similar to baseline within the 10-min hypoxia period. Neuronal activity also showed a peak at the onset of hypoxia, but dropped back to baseline as well. Despite regaining baseline sO2 levels, changes in neuronal RSN were observed. In particular, the connectivity as measured with GCaMP between anterior and posterior parts of the brain decreased. In contrast, when looking at these same connections with HbO measurements, an increase in connectivity in anterior-posterior brain areas was observed suggesting a potential neurovascular decoupling.

    Abstract The more plant species grow together, the higher the yield. Higher plant species richness may also increase drought resistance, i.e. yield preservation during droughts. However, the mechanisms underlying these positive biodiversity effects are still debated. I this thesis, I investigated whether diversity in root characteristics or ‘traits’, such as rooting depth, can explain increased yield, or ‘overyielding’, and drought resistance in grassland plant communities. My results show that, although diversity in roots traits could not explain overyielding, root traits – and deep rooting in particular – were important: communities with deep-rooting species performed better than expected. Further, overyielding of deep-rooting species in diverse communities increased when growing with shallow-rooting neighbours, supporting the importance of rooting depth diversity. This research shows that rooting strategies play an important role in the positive effect of plant diversity on yield production. We found no evidence that plant species richness or root trait diversity increased drought resistance, perhaps due to extremeness of the drought treatment. On the contrary, drought decreased overyielding. Future biodiversity research at different drought intensity levels may further increase our insights on how biodiversity affect the drought resistance of our grasslands.

    Title translation Ethical principles compromised during the COVID-19 pandemic?
    Abstract In the late 1970s, the American bioethicists Tom Beauchamp and James Childress described the four ethical principles that should guide a physician's actions in individual patient care. These principles are: (a) respect for autonomy; (b) doing well (beneficence); (c) not harming (non-maleficence); and (d) justice. In many countries, the global outbreak of SARS-CoV-2 has led to overloaded healthcare systems due to large numbers of COVID-19 patients. In order to provide care to this high volume of patients, far-reaching measures are taken that affect everyone. These measures are not taken from an individual patient's perspective but in the interest of public health; nonetheless, they can directly affect the individual patient's interests. This article examines the extent to which Beauchamp and Childress' ethical principles may be compromised during the COVID-19 pandemic.

    Title translation Within the limits of the law? Compulsory isolation and compulsory treatment for tuberculosis.
    Abstract We discuss two patients with infectious tuberculosis who underwent compulsory isolation and treatment without their consent. We describe the threat to the patient's rights, i.e. the right of freedom, the right of autonomy and the right of protection of the integrity of the body. We describe the application of the relevant laws and of the differing safeguards, and discuss the unlimited length of the Dutch Public Health Act orders. We refer to a Dutch statement and the WHO ethics guidelines on the implementation of their End TB Strategy. Forced isolation may be the last resort to protect society from patients with infectious diseases who do not comply with isolation measures, but compulsory treatment for tuberculosis patients is considered unacceptable. We suggest an amendment of the Dutch Public Health Act to enable better protection of the rights of tuberculosis patients.

    Abstract Vascular graft and endograft infection (VGEI) is a severe complication associated with high mortality and is often challenging to diagnose. For the definitive microbiological diagnosis, sonication of vascular grafts may increase the microbiological yield of these biofilm-associated infections. The objective of this study was to determine whether sonication of explanted vascular grafts and endografts results in a higher diagnostic accuracy than conventional culture methods and aids in clinical decision-making. A prospective diagnostic study was performed comparing conventional culture with sonication culture of explanted vascular grafts in patients treated for VGEI. Explanted (endo)grafts were cut in halves and were either subjected to sonication or conventional culture. Criteria based on the Management of Aortic Graft Infection Collaboration (MAGIC) case definition of VGEI were used for definitive diagnosis. The relevance of sonication cultures was assessed by expert opinion to determine the clinical impact on decision-making. Fifty-seven vascular (endo)graft samples from 36 patients (four reoperations; 40 episodes) treated for VGEI were included; 32 episodes were diagnosed with VGEI. Both methods showed a positive culture in 81% of the cases. However, sonication culture detected clinically relevant microorganisms that went unnoticed by conventional culturing in 9 out of 57 samples (16%, 8 episodes) and provided additional relevant information regarding growth densities in another 11 samples (19%, 10 episodes). Sonication of explanted vascular grafts and endografts improves the microbiological yield and aids in the clinical decision-making for patients with a suspected VGEI compared to conventional culture alone.

    Abstract The lack of extreme water level fluctuations in managed, non-peat forming wetland ecosystems can result in decreased productivity through the loss of heterogeneity of these ecosystems. Stochastic disruption, such as a water level drawdown, can effectively reverse this effect and return the wetland to a more productive state, associated with higher biodiversity through new vegetation development. Yet, aside from the effect on vegetation dynamics, little is known about longer-term effects (30 years) of a water level drawdown, hereafter referred to as legacy effects, and how this may impact future water level drawdowns. Here, we aim to unravel the legacy effects of a water level drawdown, stand alone and along a water level gradient, on seed bank properties and nutrient availability in a eutrophic clay wetland. To identify these, we studied the hydrologically managed nature reserve Oostvaardersplassen in the Netherlands. Here, one section was subjected to a multi-year water level drawdown and another section was kept inundated. We determined seed bank properties in both areas, spatially and along a soil elevation gradient (20 cm). Nutrient availability was measured by taking sediment samples along the water level gradient and through experimental manipulation of the water level in an indoor mesocosm experiment. Germination was higher in locations with a water level drawdown history, especially at relatively high elevations. Additionally, the proportion of pioneer species in the seed bank was higher in the water level drawdown area. Overall, nutrient concentrations were higher compared to other aquatic systems. Nutrient availability was higher in the inundated area and did not respond to the water level gradient. We conclude that 30 years after an induced water level drawdown there is no depletion of nutrients, while we still observe a legacy effect in the number of viable seeds in the seed bank.
