    Context: Climate change is considered to be the greatest threat to global public health. It affects our food and water sources, the air we breathe and the weather we experience. Climate change is equally harmful to supermarkets: 95% of the current food supply is at risk from climate change. As fewer products become available, costs will increase not only for consumers but also for purchasers. The European Green Deal functions as a secure foundation to create a business that is focused on the protection of the environment. The aim of this policy brief is to guide industry leaders on how to transform supermarkets to function in a more sustainable way and mitigate negative environmental impacts.   Policy Options: Three policy options are presented for discussion: reduction of food waste, reduce energy efficiency, reduce plastic packaging. Supermarkets are a major factor in climate change contributing to food waste, high energy use and plastic pollution, each with negative effects. We see an urgent need and opportunity for supermarket chains to act. These policy options are presented in conjunction to allow for maximum effect of action.   Recommendations: Supermarkets should reduce fossil fuel use in transport, storage, and delivery, incorporating sustainable design into practice. Landfill and food waste should be minimised by an improved supply chain management. Harmful packaging should be diminished or replaced by alternative materials providing customers with more sustainable options.   Acknowledgments: The authors would like to acknowledge and thank John Middleton (ASPHER) for his help and support in the development of this policy brief and his insight into the field of public health during this process.

    BACKGROUND: Patient-centredness is considered a core competency for health professionals. To support faculty in designing courses focused on patient-centredness, an understanding of how educational interventions lead to patient-centredness is required. This study aims to show how learning mechanisms, which potentially contribute to patient-centredness, are triggered. METHODS: Thirty-five third-year medical students at the UMC Utrecht followed four different patients for two years. The intervention took place in an out-of-hospital setting. Students visited patients in their home circumstances and accompanied them to clinical events. Twelve students were interviewed. The realist approach was used to construct configurations which relate components of the intervention to the context and learning mechanisms. RESULTS: Following patients in their home circumstances for a prolonged period supported the development of meaningful relationships between students and patients and provided continuity. In the context of a meaningful relationship and continuity, mechanisms contributing to learning patient-centredness were triggered. The most important learning mechanisms found in this study were: reflecting, contextualising disease in a real persons' life, broadening perspectives and engaging with the patients. CONCLUSIONS: Learning mechanisms are triggered by continuity and by meaningful student-patient relationships. These can be enhanced by an out-of-hospital setting and longitudinal contact. Thus, a relationship between students and patients is an important enabler for the development of patient-centredness

    Potential of mesenchymal- and cardiac progenitor cells for therapeutic targeting of B-cells and antibody responses in end-stage heart failure

    Upon myocardial damage, the release of cardiac proteins induces a strong antibody-mediated immune response, which can lead to adverse cardiac remodeling and eventually heart failure (HF). Stem cell therapy using mesenchymal stromal cells (MSCs) or cardiomyocyte progenitor cells (CPCs) previously showed beneficial effects on cardiac function despite low engraftment in the heart. Paracrine mediators are likely of great importance, where, for example, MSC-derived extracellular vesicles (EVs) also show immunosuppressive properties in vitro. However, the limited capacity of MSCs to differentiate into cardiac cells and the sufficient scaling of MSC-derived EVs remain a challenge to clinical translation. Therefore, we investigated the immunosuppressive actions of endogenous CPCs and CPC-derived EVs on antibody production in vitro, using both healthy controls and end-stage HF patients. Both MSCs and CPCs strongly inhibit lymphocyte proliferation and antibody production in vitro. Furthermore, CPC-derived EVs significantly lowered the levels of IgG1, IgG4, and IgM, especially when administered for longer duration. In line with previous findings, plasma cells of end-stage HF patients showed high production of IgG3, which can be inhibited by MSCs in vitro. MSCs and CPCs inhibit in vitro antibody production of both healthy and end stage HF-derived immune cells. CPC-derived paracrine factors, such as EVs, show similar effects, but do not provide the complete immunosuppressive capacity of CPCs. The strongest immunosuppressive effects were observed using MSCs, suggesting that MSCs might be the best candidates for therapeutic targeting of B-cell responses in HF

    Factors determining development of researchers within a research network on cancer diagnosis in primary care (CanTest): an interview study.

    OBJECTIVES: Developing connections with other researchers in a network, learning informally through these connections and using them to reach goals, is expected to increase research capacity and strengthen performance. So far, this has not been empirically demonstrated. We assessed what and how network collaboration adds to development of researchers. DESIGN: Exploratory qualitative study using semistructured online interviews, analysed by inductive and deductive methods. For the deductive analysis, an existing value creation framework to study informal learning in networks was used and adjusted to our context. SETTING: The CanTest Collaborative-an international team of primary care cancer researchers working on early detection and diagnosis of cancer. PARTICIPANTS: Sixteen primary care cancer researchers. RESULTS: Connections with other researchers in an international network created diverse value cycles, where most outcomes were in the potential value cycle, acquiring knowledge, skills, social capital, resources and ideas. Not all potential value will be applied but many interviewees described realised as well as transformational value. In our context, the transformational value from the framework appeared to be related to other perspectives on the research process. Advancement of the network depends on opportunities, timing, role models and connections between different perspectives. CONCLUSIONS: Focus on the factors that are relevant for network advancement will support researchers in early detection and diagnosis of cancer research patients who participate in an international network and bring sustainable change in this domain. When, subsequently, researchers in the CanTest network bring about more realised and transformational learning outcomes, this will contribute to capacity development

    Genotype-phenotype correlation in pseudoxanthoma elasticum

    Background and aims: Pseudoxanthoma elasticum (PXE) is caused by variants in the ABCC6 gene. It results in calcification in the skin, peripheral arteries and the eyes, but has considerable phenotypic variability. We investigated the association between the ABCC6 genotype and calcification and clinical phenotypes in these different organs. Methods: ABCC6 sequencing was performed in 289 PXE patients. Genotypes were grouped as two truncating, mixed, or two non-truncating variants. Arterial calcification mass was quantified on whole body, low dose CT scans; and peripheral arterial disease was measured with the ankle brachial index after treadmill test. The presence of pseudoxanthoma in the skin was systematically scored. Ophthalmological phenotypes were the length of angioid streaks as a measure of Bruchs membrane calcification, the presence of choroidal neovascularizations, severity of macular atrophy and visual acuity. Regression models were built to test the age and sex adjusted genotype-phenotype association. Results: 158 patients (median age 51 years) had two truncating variants, 96 (median age 54 years) a mixed genotype, 18 (median age 47 years) had two non-truncating variants. The mixed genotype was associated with lower peripheral (13: 0.39, 95%CI:-0.62;-0.17) and total (13: 0.28, 95%CI:-0.47;-0.10) arterial calcification mass scores, and lower prevalence of choroidal neovascularizations (OR: 0.41 95%CI:0.20; 0.83) compared to two truncating variants. No association with pseudoxanthomas was found. Conclusions: PXE patients with a mixed genotype have less severe arterial and ophthalmological phenotypes than patients with two truncating variants in the ABCC6 gene. Research into environmental and genetic modifiers might provide further insights into the unexplained phenotypic variability

    Clinically SUspected ScaPhoid fracturE: treatment with supportive bandage or CasT? 'Study protocol of a multicenter randomized controlled trial' (SUSPECT study)

    Introduction Some scaphoid fractures become visible on radiographs weeks after a trauma which makes normal radiographs directly after trauma unreliable. Untreated scaphoid fractures can lead to scaphoid non-union progressing to osteoarthritis. Therefore, the general treatment for patients with a clinically suspected scaphoid fracture and normal initial radiographs is immobilisation with below-elbow cast for 2 weeks. However, most of these patients are treated unnecessarily because eventually less than 10% of them are diagnosed with an occult scaphoid fracture. To reduce overtreatment and costs as a result of unnecessary cast treatment in patients with a clinically suspected scaphoid fracture and normal initial radiographs, we designed a study to compare below-elbow cast treatment with supportive bandage treatment. We hypothesise that the functional outcome after 3 months is not inferior in patients treated with supportive bandage compared to patients treated with below-elbow cast, but with lower costs in the supportive bandage group. Methods and analysis The SUSPECT study is an open-labelled multicentre randomised controlled trial with non-inferiority design. A total of 180 adult patients with a clinically suspected scaphoid fracture and normal initial radiographs are randomised between two groups: 3 days of supportive bandage or 2 weeks of below-elbow cast. We aim to evaluate the functional outcome and cost-effectiveness of both treatments. The primary outcome is the functional outcome after 3 months, assessed with the Quick Disability of the Arm, Shoulder and Hand score. Secondary outcomes include functional outcome, recovery of function, pain, patient satisfaction, quality of life and cost-effectiveness measured by medical consumption, absence from work or decreased productivity. Ethics and dissemination The Medical Ethics Committee of the Erasmus MC Medical Centre, Rotterdam, approved the study protocol (MEC-2017-504). We plan to present the results after completion of the study at (inter)national conferences and publish in general peer-reviewed journals

    Perinatal death in a term fetal growth restriction randomized controlled trial:the paradox of prior risk and consent

    Get PDF
    BACKGROUND: The disproportionate intrauterine growth intervention trial at term was an intention to treat analysis and compared labor induction with expectant monitoring in pregnancies complicated by fetal growth restriction at term and showed equivalence for neonatal outcomes. OBJECTIVE: To evaluate trial participation bias and to examine the generalizability of the results of an obstetrical randomized trial. STUDY DESIGN: We used data from participants and nonparticipants of a randomized controlled trial-the disproportionate intrauterine growth intervention trial at term (n=1116) -to perform a secondary analysis. This study compared induction of labor and expectant management in women with term growth restriction. Data were collected in the same manner for both groups. Baseline characteristics and neonatal and maternal outcomes were compared. The primary outcome was a composite measure of adverse neonatal outcome. Secondary outcomes were delivery by cesarean delivery and instrumental vaginal delivery; length of stay in the neonatal intensive care, neonatal ward, and the maternal hospital; and maternal morbidity. RESULTS: Nonparticipants were older, had a lower body mass index, had a higher level of education, smoked less, and preferred expectant management. The time between study inclusion and labor onset was shorter in participants than in nonparticipants. Notably, 4 perinatal deaths occurred among nonparticipants and none among participants. Among nonparticipants, there were more children born with a birthweight below the third centile. The nonparticipants who had expectant management were monitored less frequently than the participants in both the intervention and the expectant arm. CONCLUSION: We found less favorable outcomes and more perinatal deaths in nonparticipants. Protocol-driven management, differences between participants and nonparticipants, or the fact that nonparticipants had a preference for expectant management might explain the findings
