Family care-when partners, relatives, or other proxies care for each other in case of illness, disability, or frailty-is increasingly considered an important pillar for the sustainability of care systems. For many people, taking on a caring role is self-evident. Especially in a palliative care context, however, family care can be challenging. Witnessing caregivers' challenges may prompt compassionate nurses to undertake actions to reduce burden by adjusting tasks or activities. Using a care ethical approach, this theoretical paper aims to provide nurses with an alternative perspective on caregiver burden and support. Drawing on the concepts of relationality and contextuality, we explain that family care often is not a well-demarcated or actively chosen task. Instead, it is a practice of responding to an all-encompassing "call" to care flowing from a relationship, within a social and cultural context where norms, motivations, and expectations shape people's (sometimes limitless) care. We consider relational interdependence at the root of persisting in care provision. The question is then whether self-sacrifice is a problem that nurses should immediately solve. In ideal circumstances, self-sacrifice is the result of a conscious balancing act between values, but family care in the context of serious illness barely provides room for reflection. Yet, instant attempts to alleviate burden may overlook family caregivers' values and the inherent moral ambiguities and/or ambivalent feelings within family care. Family care is complex and highly personal, as is finding an adequate balance in fulfilling one's sometimes conflicting values, motivations, and social expectations. Therefore, we suggest that caregiver experiences should always be interpreted in an explorative dialogue, focused on what caring means to a particular family caregiver. Nurses do not have to liberate family caregivers from the situation but should support them in whatever overwhelms or drives them in standing-by their loved ones until the end., Competing Interests: Declaration of conflicting interestThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: MH declared that she is the coauthor of the graphic novel to which this paper refers.

Purpose: Organizational culture is considered a protective factor against burnout among ICU professionals. The aim of this study is to study the association between organizational culture as a potential antecedent to previously found mediating risk factors for burnout, namely, work-life balance and moral distress., Materials and Methods: Multicenter cross sectional study in eleven Dutch ICUs. The primary outcome measure was the core symptom of burnout, emotional exhaustion, measured using the validated Dutch version of the Maslach Burnout Inventory. Organizational culture was assessed using the Culture of Care Barometer, which measures five aspects of organizational culture. Moral distress and work-life balance were measured with validated questionnaires., Results: 696 ICU professionals (39.7 %) responded. All aspects of the CoCB were negatively associated with the emotional exhaustion component of burnout, both in univariable and multivariable models. Four aspects of organizational culture were significantly associated to the serial association between moral distress, work-to-home spillovers, and emotional exhaustion. For these aspects, the total indirect association was equal or larger than the total direct association., Conclusions: Multiple aspects of organizational culture reduce burnout among ICU professionals in a largely indirect manner, via moral distress and work-life balance. Improving organizational culture can mitigate burnout symptoms among ICU clinicians., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The Dutch graphic novel Naasten , about palliative family caregiving, is the product of an interdisciplinary collaboration between researchers and two comic artists. This paper aims to present lessons, reflections and practical recommendations for other researchers interested in adopting (comic) arts-based research methods, in which artistic methods are used as novel ways for generating, analysing, interpreting or representing research data.Our project started with the goal of translation: we aimed at representing research findings into a more accessible, visual and textual form to stimulate discussion and reflection outside academia on moral challenges in family care. This was inspired by comics' hypothesised potential to show complex and embodied experiences, thus enabling more understanding in readers and offering powerful science communication tools. Although this goal of translation was realised in our project, we learnt along the way that the project could have benefited from a more explicit focus on interdisciplinarity from the start and by monitoring the interdisciplinary learning opportunities throughout the project. The following issues are important for any art-research collaboration: (1) an interest in and acknowledgement of each other's (potentially diverging) aims and roles: all parties should-from the start-commit themselves to interdisciplinary collaboration and to exploring the added value of using each other's methods, thereby finding a common methodological ground and language; (2) a continuous discussion of the sometimes contrasting approaches between artists and researchers: differences in using theory and story may result in different criteria for creating good art. When balancing scientific and aesthetic aims, the trustworthiness of the art work should remain an important criterion; (3) an awareness of the potential of interdisciplinary collaboration to offering new perspectives on one's scientific data collection and analysis, for example, providing other conceptualisations or indicating blind spots, provided that artists are involved in the early phases of research., Competing Interests: Competing interests: MH declared that she is coauthor of the graphic novel on which this study was based.

Intensive care unit (ICU) professionals engage in ethical decision making under conditions of high stakes, great uncertainty, time-sensitivity and frequent irreversibility of action. Casuistry is a way by which actionable knowledge is obtained through comparing a patient case to previous cases from experience in clinical practice. However, within the field of study as well as in practice, evidence-based medicine is the dominant epistemic framework. This multiple case study evaluated the use of casuistic reasoning by intensive care unit (ICU) professionals during moral case deliberation. It took place in two Dutch hospitals between June 2020 and June 2022. Twentyfive moral case deliberations from ICU practice were recorded and analyzed using discourse analysis. Additionally, 47 interviews were held with ICU professionals who participated in these deliberations, analyzed using thematic analysis. We found that ICU professionals made considerable use of case comparisons when discussing continuation, withdrawal or limitation. Analogies played a role in justifying or complicating moral judgements, and also played a role in addressing moral distress. The language of case-based arguments is most often not overtly normative. Rather, the data shows that casuistic reasoning deals with the medical, ethical and contextual elements of decisions in an integrated manner. Facilitators of MCD have an essential role in (supporting ICU professionals in) scrutinizing casuistic arguments. The data shows that during MCD, actual reasoning often deviated from principle- and rule-based reasoning which ICU professionals preferred themselves. Evidence-based arguments often gained the character of analogical arguments, especially when a patient-at-hand was seen as highly unique from the average patients in the literature. Casuistic arguments disguised as evidence-based arguments may therefore provide ICU professionals with a false sense of certainty. Within education, we should strive to train clinicians and ethics facilitators so that they can recognize and evaluate casuistic arguments., Competing Interests: Declaration of competing interest None declared., (Copyright © 2024 The Authors.

Background: Patients with advanced cancer who no longer have standard treatment options available may decide to participate in early phase clinical trials (i.e. experimental treatments with uncertain outcomes). Shared decision-making (SDM) models help to understand considerations that influence patients' decision. Discussion of patient values is essential to SDM, but such communication is often limited in this context and may require new interventions. The OnVaCT intervention, consisting of a preparatory online value clarification tool (OnVaCT) for patients and communication training for oncologists, was previously developed to support SDM. This study aimed to qualitatively explore associations between patient values that are discussed between patients and oncologists during consultations about potential participation in early phase clinical trials before and after implementation of the OnVaCT intervention., Methods: This study is part of a prospective multicentre nonrandomized controlled clinical trial and had a between-subjects design: pre-intervention patients received usual care, while post-intervention patients additionally received the OnVaCT. Oncologists participated in the communication training between study phases. Patients' initial consultation on potential early phase clinical trial participation was recorded and transcribed verbatim. Applying a directed approach, two independent coders analysed the transcripts using an initial codebook based on previous studies. Steps of continuous evaluation and revision were repeated until data saturation was reached., Results: Data saturation was reached after 32 patient-oncologist consultations (i.e. 17 pre-intervention and 15 post-intervention). The analysis revealed the values: hope, perseverance, quality or quantity of life, risk tolerance, trust in the healthcare system/professionals, autonomy, social adherence, altruism, corporeality, acceptance of one's fate, and humanity. Patients in the pre-intervention phase tended to express values briefly and spontaneously. Oncologists acknowledged the importance of patients' values, but generally only gave 'contrasting' examples of why some accept and others refuse to participate in trials. In the post-intervention phase, many oncologists referred to the OnVaCT and/or asked follow-up questions, while patients used longer phrases that combined multiple values, sometimes clearly indicating their weighing., Conclusions: While all values were recognized in both study phases, our results have highlighted the different communication patterns around patient values in SDM for potential early phase clinical trial participation before and after implementation of the OnVaCT intervention. This study therefore provides a first (qualitative) indication that the OnVaCT intervention may support patients and oncologists in discussing their values., Trial Registration: Netherlands Trial Registry: NL7335, registered on July 17, 2018., (© 2024.

Background: Burnout threatens intensive care unit (ICU) professionals' capacity to provide high-quality care. Moral distress is previously considered a root cause of burnout, but there are other risk factors of burnout such as personality, work-life balance and culture. This study aimed to disentangle the associations of ICU professionals' moral distress and other risk factors with the components of burnout-emotional exhaustion, depersonalisation and personal accomplishment-suggesting informed burnout prevention strategies., Methods: Cross-sectional survey completed in 2019 of ICU professionals in two Dutch hospitals. The survey included validated measure for burnout (the Dutch Maslach Burnout Inventory), moral distress (Moral Distress Scale), personality (short Big Five Inventory), work-home balance (Survey Work-Home Interaction Nijmegen) and organisational culture (Culture of Care Barometer). Each of the three components of burnout was analysed as a separate outcome, and for each of the components, a separate regression analysis was carried out., Results: 251 ICU professionals responded to the survey (response rate: 53.3%). Burnout prevalence was 22.7%. Findings showed that moral distress was associated with emotional exhaustion (β=0.18, 95% CI 0.9 to 0.26) and depersonalisation (β=0.19, 95% CI 0.10 to 0.28) and with increased emotional exhaustion mediated by negative work-to-home spillover (β=0.09, 95% CI 0.04 to 0.13). Support from direct supervisors mitigates the association between moral distress and emotional exhaustion (β=0.16, 95% CI 0.04 to 0.27)., Conclusions: Understanding moral distress as a root cause of burnout is too simplified. There is an important interplay between moral distress and work-home imbalance. Interventions that support individual coping with moral distress and a work-home imbalance, and the support of direct supervisors, are paramount to prevent burnout in physicians and nurses., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objectives: During the COVID-19 pandemic, ICU professionals have faced moral problems that may cause moral injury. This study explored whether, how, and when moral injury among ICU professionals developed in the course of the COVID-19 pandemic., Design: This is a prospective qualitative serial interview study., Setting: Two hospitals among which one university medical center and one teaching hospital in the Netherlands., Subjects: Twenty-six ICU professionals who worked during the COVID-19 pandemic., Interventions: None., Measurements Main Results: In-depth interviews with follow-up after 6 and 12 months. In total, 62 interviews were conducted. ICU professionals narrated about anticipatory worry about life and death decisions, lack of knowledge and prognostic uncertainty about COVID-19, powerlessness and failure, abandonment or betrayal by society, politics, or the healthcare organization, numbness toward patients and families, and disorientation and self-alienation. Centrally, ICU professionals describe longitudinal processes by which they gradually numbed themselves emotionally from patients and families as well as potentially impactful events in their work. For some ICU professionals, organizational, societal, and political responses to the pandemic contributed to numbness, loss of motivation, and self-alienation., Conclusions: ICU professionals exhibit symptoms of moral injury such as feelings of betrayal, detachment, self-alienation, and disorientation. Healthcare organizations and ICU professionals themselves should be cognizant that these feelings may indicate that professionals might have developed moral injury or that it may yet develop in the future. Awareness should be raised about moral injury and should be followed up by asking morally injured professionals what they need, so as to not risk offering unwanted help., Competing Interests: Drs.

Background: Palliative care involves the care for patients with severe and advanced diseases with a focus on quality of life and symptom management. Integration of palliative care with curative and/or chronic care is expected to lead to better results in terms of quality of life and reduced costs. Although initiatives in different countries in Europe choose different structures to integrate care, they face similar challenges when it comes to creating trust and aligning visions, cultures and professional values. This paper sets out to answer the following research question: what roles and attitudes do palliative care professionals need to adopt to further integrate palliative care in Europe?, Methods: As part of the European Union (EU)-funded research project InSup-C (Integrated Supportive and Palliative Care). (2012-2016), 19 semi-structured group interviews with 136 (palliative) care professionals in 5 European countries (Germany, the United Kingdom, Belgium, the Netherlands, Hungary) were conducted. A thematic analysis was conducted., Results: Integration of palliative care calls for diplomatic professionals that can bring a cultural shift: to get palliative care, with its particular focus on the four dimensions (physical, psychological, social, spiritual), integrated into historically established medical procedures and guidelines. This requires (a) to find an entrance (for telling a normative story), and (b) to maintain and deepen relationships (in order to build trust). It means using the appropriate words and sending a univocal team message to patients and being grateful, modest, and aiming for a quiet revolution with curation oriented healthcare professionals., Conclusion: Diplomacy appears to be essential to palliative care providers for realizing trust and what can be defined as normative integration between palliative and curative and/or chronic medicine. It requires a practical wisdom about the culture and goals of regular care, as well as keeping a middle road between assimilating with values in regular medicine and standing up for the basic values central to palliative care., (© 2022 The Author(s); Published by Kerman University of Medical Sciences This is an open-access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.)

There is a claim that clinical ethics support services (CESS) improve healthcare quality within healthcare organisations. However, there is lack of strong evidence supporting this claim. Rather, the current focus is on the quality of CESS themselves or on individual learning outcomes. In response, this article proposes a theoretical framework leading to empirical hypotheses that describe the relationship between a specific type of CESS, moral case deliberation and the quality of care at the organisational level. We combine insights from the literature on CESS, organisational learning and quality improvement and argue that moral case deliberation causes healthcare professionals to acquire practical wisdom. At the organisational level, where improving quality is a continuous and collective endeavour, this practical wisdom can be aggregated into morisprudence, which is an ongoing formulation of moral judgements across cases encountered within the organisation. Focusing on the development of morisprudence enables refined scrutinisation of CESS-related quality claims., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: For many patients with advanced cancer, the decision whether to participate in early phase clinical trials or not is complex. The decision-making process requires an in-depth discussion of patient values. We therefore aimed to synthesize and describe patient values that may affect early phase clinical trial participation., Methods: We conducted a systematic search in seven electronic databases on patient values in relation to patients' decisions to participate in early phase clinical cancer trials., Results: From 3072 retrieved articles, eleven quantitative and five qualitative studies fulfilled our inclusion criteria. We extracted ten patient values that can contribute to patients' decisions. Overall, patients who seek trial participation usually report hope, trust, quantity of life, altruism, perseverance, faith and/or risk tolerance as important values. Quality of life and humanity are main values of patients who refuse trial participation. Autonomy and social adherence can be reported by both trial seekers or refusers, dependent upon how they are manifested in a patient., Conclusions: We identified patient values that frequently play a role in the decision-making process. In the setting of discussing early phase clinical trial participation with patients, healthcare professionals need to be aware of these values. This analysis supports the importance of individual exploration of values. Patients that become aware of their values, e.g. by means of interventions focused on clarifying their values, could feel more empowered to choose. Subsequently, healthcare professionals could improve their support in a patients' decision-making process and reduce the chance of decisional conflict., (Copyright © 2021 The Author(s).

Barrett's esophagus (BE) is a premalignant metaplasia in patients with chronic gastroesophageal reflux disease (GERD). BE can progress to esophageal adenocarcinoma (EA) with less than 15% 5-year survival. Chromosomal aneuploidy, deletions, and duplication are early events in BE progression to EA, but reliable diagnostic assays to detect chromosomal markers in premalignant stages of EA arising from BE are lacking. Previously, we investigated chromosomal changes in an in vitro model of acid and bile exposure-induced Barrett's epithelial carcinogenesis (BEC). In addition to detecting changes already known to occur in BE and EA, we also reported a novel recurring chromosomal translocation t(10:16) in the BE cells at an earlier time point before they undergo malignant transformation. In this study, we refine the chromosomal event with the help of fluorescence microscopy techniques as a three-way translocation between chromosomes 2, 10, and 16, t(2:10;16) (p22;q22;q22). We also designed an exclusive fluorescent in situ hybridization for esophageal adenocarcinoma (FISH-EA) assay that detects these chromosomal breakpoints and fusions. We validate the feasibility of the FISH-EA assay to objectively detect these chromosome events in primary tissues by confirming the presence of one of the fusions in paraffin-embedded formalin-fixed human EA tumors. Clinical validation in a larger cohort of BE progressors and non-progressors will confirm the specificity and sensitivity of the FISH-EA assay in identifying malignant potential in the early stages of EA., Competing Interests: MB, HA, and KD have a patent application U.S. Application No. 16/083,055 pending for the FISH-EA probes.

Background: Based on the case of palliative care and euthanasia in the Netherlands, this paper presents an analysis of frames and counter-frames used in the ongoing public debate about these two intertwined topics. Each (counter)frame presents a cultural theme that can act as a prism to give meaning to palliative care and/or euthanasia. Each frame comprehends a different problem definition, consequences and policy options. Typical word choices and metaphors are identified that can evoke these frames and the underlying reasoning. The frames do not belong to a specific stakeholder but a pattern can be seen in their use that is related to interests and ideology., Methods: An inductive framing analysis was conducted of 2,700 text fragments taken from various Dutch newspapers, websites of stakeholders and policy documents in the period 2016-2018. After an extensive process of thematic coding, axial coding, selective coding and peer review seven frames and seven counter-frames about palliative care and euthanasia were constructed. Fifteen experts in the field of palliative and/or end-of-life care commented on the overview during a member check., Results: Two frames about palliative care were constructed: the Fear of death frame, which stresses the hopeless 'terminality' of palliative care and the Heavy burden frame, in which palliative care is too big a responsibility for the relatives of the patient. In addition, two counter-frames were constructed: palliative care as a contributor to Quality of life and Completion. With regard to euthanasia, five frames were identified that lead to a problematising definition: Thou shalt not kill, Slippery slope, Lack of willpower, I am not God, and Medical progress. Five counter-frames offer a non-problematising definition of euthanasia in the debate: Mercy, Prevention, Triumph of reason, Absolute autonomy, and Economic utility thinking., Conclusions: The debate in the Netherlands on euthanasia and palliative care is characterized by a plurality of angles that goes beyond the bipolar distinction between the pros and cons of euthanasia and palliative care. Only with an overview of all potential frames in mind can an audience truly make informed decisions. The frame matrix is not only useful for policy makers to know all perspectives when joining public debate, but also to health care workers to get into meaningful conversations with their patients and families.

Objectives: ICU professionals are at risk of developing burnout due to coronavirus disease 2019. This study assesses the prevalence and incidence of burnout symptoms and moral distress in ICU professionals before and during the coronavirus disease 2019 crisis., Design: This is a longitudinal open cohort study., Setting: Five ICUs based in a single university medical center plus another adult ICU based on a separate teaching hospital in the Netherlands., Subjects: All ICU professionals were sent a baseline survey in October-December 2019 (252 respondents, response rate: 53%), and a follow-up survey was sent in May-June 2020 (233 respondents, response rate: 50%)., Interventions: None., Measurements and Main Results: Burnout symptoms and moral distress measured with the Maslach Burnout Inventory and the Moral Distress Scale, respectively. The prevalence of burnout symptoms was 23.0% before coronavirus disease 2019 and 36.1% at postpeak time, with higher rates in nurses (38.0%) than in physicians (28.6%). Reversely, the incidence rate of new burnout cases among physicians was higher (26.7%) than nurses (21.9%). Higher prevalence of burnout symptoms was observed in the postpeak coronavirus disease 2019 period (odds ratio, 1.83; 95% CI, 1.32-2.53), for nurses (odds ratio, 1.77; 95% CI, 1.03-3.04), for professionals working overtime (odds ratio 2.11; 95% CI, 1.48-3.02), and for professionals directly engaged with care for coronavirus disease 2019 patients (odds ratio, 1.87; 95% CI, 1.35-2.60). Physicians were more likely than nurses to develop burnout symptoms due to coronavirus disease 2019 (odds ratio, 3.56; 95% CI, 1.06-12.21)., Conclusions: This study shows that overburdening of ICU professionals during an extended period of time leads to symptoms of burnout. Working long hours and under conditions of scarcity of staff, time, and resources comes at the price of ICU professionals' mental health., Competing Interests: Mr. Kok’s and Dr. Zegers’ institution received funding from ZonMw.

Background: Patients with advanced cancer for whom standard systemic treatment is no longer available may be offered participation in early phase clinical trials. In the decision making process, both medical-technical information and patient values and preferences are important. Since patients report decisional conflict after deciding on participation in these trials, improving the decision making process is essential. We aim to develop and evaluate an Online Value Clarification Tool (OnVaCT) to assist patients in clarifying their values around this end-of-life decision. This improved sharing of values is hypothesized to support medical oncologists in tailoring their information to individual patients' needs and, consequently, to support patients in taking decisions in line with their values and reduce decisional conflict., Methods: In the first part, patients' values and preferences and medical oncologists' views hereupon will be explored in interviews and focus groups to build a first prototype OnVaCT using digital communication (serious gaming). Next, we will test feasibility during think aloud sessions, to deliver a ready-to-implement OnVaCT. In the second part, the OnVaCT, with accompanied training module, will be evaluated in a pre-test (12-18 months before implementation) post-test (12-18 months after implementation) study in three major Dutch cancer centres. We will include 276 patients (> 18 years) with advanced cancer for whom standard systemic therapy is no longer available, and who are referred for participation in early phase clinical trials. The first consultation will be recorded to analyse patient-physician communication regarding the discussion of patients' values and the decision making process. Three weeks afterwards, decisional conflict will be measured., Discussion: This project aims to support the discussion of patient values when considering participation in early phase clinical trials. By including patients before their first appointment with the medical oncologist and recording that consultation, we are able to link decisional conflict to the decision making process, e.g. the communication during consultation. The study faces challenges such as timely including patients within the short period between referral and first consultation. Furthermore, with new treatments being developed rapidly, molecular stratification may affect the patient populations included in the pre-test and post-test periods., Trial Registration: Netherlands Trial Registry number: NTR7551 (prospective; July 17, 2018).

Adrenal-renal fusion is an anomaly misclassified as a renal tumor due to the absence of pathognomonic radiographic features. Herein, we report a case of a 61-year-old male who underwent a right radical nephrectomy for a presumed renal malignancy. Pathologic evaluation demonstrated a pheochromocytoma in the context of adrenal-renal fusion. Neoplastic transformation of fused adrenal tissue is rare but not unheard of and is typically adrenal cortical in origin. To our knowledge, this is the first description of a pheochromocytoma originating from an adrenal-renal fusion. The clinical presentation did not raise a high index of suspicion for the ultimate diagnosis rendered.

Background: The role of 5-aminosalicylic acid (5-ASA or mesalamine) in the prevention of colorectal cancer in ulcerative colitis (UC) patients was reported, but the effect on molecular targets in UC colon mucosa is unknown., Aim: This observational study evaluates gene expression levels of 5-ASA targets using serial colon biopsy specimens from UC patients undergoing long-term 5-ASA therapy., Methods: Transcript levels were compared between colonoscopic biopsy specimens collected from 62 patients at initial and final follow-up colonoscopy at 2-6 years. All patients had mild-to-moderate UC and were undergoing long-term 5-ASA maintenance. Stepwise multiple linear regression analyses were performed to correlate changes in transcript levels with therapeutic response (Mayo clinical score endoscopy and DAI and/or Nancy histopathology score) and nonclinical variables., Results: The transcript levels of colorectal carcinogenesis-associated known 5-ASA target genes were significantly reduced after prolonged 5-ASA therapy (P < 0.005-0.03). Multiple linear regression models predicted significant association between transcript levels of Ki-67, NF-kB (p65), PPARγ, COX-2 and IL-8, CDC25A, and CXCL10 with duration of drug (5-ASA) exposure (P ≤ 0.05). Ki-67, NF-kB (p65), and CXCL10 transcripts were also correlated with reduced endoscopy sub-score (P ≤ 0.05). COX-2, IL-8, CDC25A, and TNF transcripts strongly correlated with DAI sub-scores (P ≤ 0.05). Only COX-2 and IL-8 transcript levels correlated (P ≤ 0.05) with Nancy histological score., Conclusion: This study provides molecular evidence of changes in carcinogenesis-related targets/pathways in colon tissue during long-term 5-ASA maintenance therapy that may contribute to the observed chemopreventive effects of 5-ASA in UC patients.

Background: MicroRNAs (miRNAs) are important post-translational regulators. Elevated levels of miR-206 in ulcerative colitis (UC) were associated with suppression of anti-inflammatory A3 adenosine receptor (A3AR) expression. However, the relationship of miR-206 to histologic remission in UC patients remains unknown. This study correlates expression levels of miR-206 with histologic remission in patients treated via long-term mesalamine treatment to identify a possible mode of action for this mainstay drug for UC., Methods: Expression of miR-206 and its target A3AR were analyzed in HT29 cell line before and after mesalamine treatment (2 mM) at different time points (0, 4, 12, and 24 hours) by qRT-PCR and western blot analysis. Expression of miR-206 and pathological scores of colonoscopic biopsy specimens were studied in 10 UC patients treated with mesalamine treatment for 2 to 6 years., Results: miR-206 transcripts decreased 2.23-fold (P = 0.0001) 4 hours after 2 mM mesalamine treatment in HT29 colon cells compared with untreated controls. However, the mRNA/protein levels of A3AR increased by 4-fold (P = 0.04) and 2-fold, respectively, in same cells. miR-206 relative expression decreased significantly in patients treated with 4.8 g of mesalamine (P = 0.002) but not with 2.4 g (P = 0.35). Tissue assessment of sequential mesalamine-treated colonoscopic biopsies indicate a strong correlation between downregulation of miR-206 and histologic improvement (R = 0.9111)., Conclusion: Mesalamine treatment has an effect on epithelial miRNAs. Downregulation of miR-206 by long-term mesalamine treatment may confer a protective effect in inducing and maintaining histologic remission. Thus, miR-206 expression levels can be utilized as a possible biomarker for therapeutic response to mesalamine treatment.

Although vaccinating seems self-evident, the immunization coverage in the Netherlands is decreasing. This decrease is often attributed to a lack of knowledge amongst the public. We argue, however, that it is rather a lack of trust that drives this reduction in uptake. In this article we discuss the role that trust, or rather a lack thereof, plays in vaccination refusal. We underpin our argument with a recent exploration of the way in which vaccination programmes are framed in newspaper articles and on internet forums. We show the importance of rumours and shared experiences (i.e. social influencing) in parents' decision-making process when they consider whether or not to vaccinate their child. To conclude, we argue for the development of positive influence strategies to counteract negative influences from outside the medical profession.
