'It's Powerful' The impact of involving children and young people in developing paediatric research agendas: A qualitative interview study.

INTRODUCTION: There is a growing consensus that children and young people (CYP) should be involved in matters that concern them. Progress is made in involving CYP in developing pediatric research agendas (PRAs), although the impact of their involvement remains unknown. We aimed to evaluate the impact of involving CYP in developing PRAs and assess the extent to which postpatient and public involvement (post-PPI) activities were planned. METHODS: We conducted a qualitative study using in-depth interviews to identify and gain an in-depth understanding of the impact of involving CYP in developing PRAs. The transcripts were uploaded to Atlas.ti to be coded and organised. Dutch-language interviews were analysed and interpreted together with vocational education and training (VET) students. These students were aged between 14 and 18 years and were training to become nurses. RESULTS: Three CYP and 15 researchers decided to participate. We focused on three categories of impact: agenda-setting impact, individual impact and academic impact. Involving CYP creates a more enriched and clarified agenda. It ensured that both CYP and researchers underwent personal or professional growth and development, it created a connection between the people involved, awareness about the importance of involving CYP and it ensured that the people involved had a positive experience. The participants were unable to indicate the academic impact of their PRAs, but they did understand the key factors for creating it. In addition, the need to measure impact was highlighted, with a particular focus on assessing individual impact. DISCUSSION: Our study outlines the diverse subthemes of impact that arise from involving CYP in developing PRAs. Despite the potential of research agendas to amplify CYP voices, only a minority of researchers strategized post-PPI activities ensuring impactful outcomes, prompting the need for thorough evaluation of various impact forms and consistent alignment with the overarching goal of transforming the research field. PATIENT OR PUBLIC CONTRIBUTION: We involved VET students in the data analysis and interpretation phase by forming a young person advisory group. The data analysis of the interviews analysed by the VET students revealed four distinct themes: 1. Learnt new knowledge. 2. Learnt to collaborate. 3. Learnt to listen. 4. Assessment of the individual impact.

A Dutch paediatric palliative care guideline: a systematic review and evidence-based recommendations for symptom treatment.

BACKGROUND: Children with life-threatening and life-limiting conditions can experience high levels of suffering due to multiple distressing symptoms that result in poor quality of life and increase risk of long-term distress in their family members. High quality symptom treatment is needed for all these children and their families, even more so at the end-of-life. In this paper, we provide evidence-based recommendations for symptom treatment in paediatric palliative patients to optimize care. METHODS: A multidisciplinary panel of 56 experts in paediatric palliative care and nine (bereaved) parents was established to develop recommendations on symptom treatment in paediatric palliative care including anxiety and depression, delirium, dyspnoea, haematological symptoms, coughing, skin complaints, nausea and vomiting, neurological symptoms, pain, death rattle, fatigue, paediatric palliative sedation and forgoing hydration and nutrition. Recommendations were based on evidence from a systematic literature search, additional literature sources (such as guidelines), clinical expertise, and patient and family values. We used the GRADE methodology for appraisal of evidence. Parents were included in the guideline panel to ensure the representation of patient and family values. RESULTS: We included a total of 18 studies that reported on the effects of specific (non) pharmacological interventions to treat symptoms in paediatric palliative care. A few of these interventions showed significant improvement in symptom relief. This evidence could only (partly) answer eight out of 27 clinical questions. We included 29 guidelines and two textbooks as additional literature to deal with lack of evidence. In total, we formulated 221 recommendations on symptom treatment in paediatric palliative care based on evidence, additional literature, clinical expertise, and patient and family values. CONCLUSION: Even though available evidence on symptom-related paediatric palliative care interventions has increased, there still is a paucity of evidence in paediatric palliative care. We urge for international multidisciplinary multi-institutional collaboration to perform high-quality research and contribute to the optimization of symptom relief in palliative care for all children worldwide.

How to move forward in shared decision-making in pediatric palliative care.

Pediatric palliative care has grown immensely in recent years in the world. However, shared decision-making remains a complex process, especially in pediatric palliative care. In particular, a number of issues are priorities to improve the shared decision-making process and ensure high-quality pediatric palliative care for every child. Working on these priorities will improve shared decision-making and thereby enhance high-quality pediatric palliative care around the globe.

Asymptomatic esophageal perforation discovered after elective cardiac surgery: the importance of clinical awareness.

Transesophageal echocardiography (TEE) has become an indispensable part of cardiothoracic surgery at present and is considered to be a safe procedure, rarely associated with complications. However, TEE may cause serious and life threatening complications, as presented in this case report. We describe a patient who developed an empyema after elective cardiac surgery due to an esophageal perforation caused by TEE, without any clinical symptoms. Risk factors for TEE-related complications, identified in recent literature, will be discussed as well as the remarkable absence of clinical symptoms in this particular patient.

[Active life termination in children aged 1-12 years]. / Actieve levensbeëindiging bij kinderen van 1-12 jaar.

In this article we discuss active termination of life in children aged 1-12 years. It is expected that in 2024 active termination of life will be regulated for children between the ages of 1 and 12 who suffer unbearably, when other options to relieve their suffering are not enough. Using a case, we describe how a request for active termination of life in a child can arise and how physicians can respond to it.

Botulinum toxin and conservative treatment strategies in people with cervical dystonia: an online survey.

Isolated cervical dystonia is a focal, idiopathic dystonia affecting the neck muscles. Treatment usually consists of botulinum neurotoxin (BoNT) injections into the dystonic muscles. Our aim is to investigate the use of BoNT treatment and conservative treatments by people living with cervical dystonia. An online survey in English was conducted between June and August 2022. Participants were eligible to participate if they were living with cervical dystonia, were over 18 years old and could read and understand English. The survey consisted of demographic questions, characteristics of dystonia, questions relating to BoNT use and the perceived utility of conservative treatments. The data were analysed descriptively, and open-ended questions were grouped into similar topics represented by direct quotes. We received 128 responses from people with cervical dystonia, with an average age of 59 years and 77% women. Most participants (52%) described their cervical dystonia as mild to moderate with an average pain score of 5/10. Eighty-two (64%) participants were having regular BoNT injections, with overall positive perceived effects. Common activities reported to improve the symptoms were the use of heat packs, massage, relaxation, physiotherapy and participation in general exercise. Common coping strategies reported were getting sufficient rest, having the support of friends and family, and remaining engaged in enjoyable hobbies. We found that most participants received regular BoNT injections and that heat packs, exercise, massage, physiotherapy and relaxation were mostly perceived as effective in reducing the symptoms of cervical dystonia.

Pediatric palliative care across continents: Communication and shared-decision-making.

Despite the significant growth and development of pediatric palliative care worldwide, significant challenges remain. One of those challenges is shared decision-making, by which parents, families and professionals all work together to develop a plan of care that reflects both the medical facts and the patient's family's values. Shared decision-making about palliative care and about death and dying may mean different things in different cultures and countries. It is therefore important to learn and compare practices around the world.

Palliative care for children: methodology for the development of a national clinical practice guideline.

BACKGROUND: Provision of paediatric palliative care for children with life-threatening or life-limiting conditions and their families is often complex. Guidelines can support professionals to deliver high quality care. Stakeholders expressed the need to update the first Dutch paediatric palliative care guideline with new scientific literature and new topics. This paper provides an overview of the methodology that is used for the revision of the Dutch paediatric palliative care guideline and a brief presentation of the identified evidence. METHODS: The revised paediatric palliative care guideline was developed with a multidisciplinary guideline panel of 72 experts in paediatric palliative care and nine (bereaved) parents of children with life-threatening or life-limiting conditions. The guideline covered multiple topics related to (refractory) symptom treatment, advance care planning and shared-decision making, organisation of care, psychosocial care, and loss and bereavement. We established six main working groups that formulated 38 clinical questions for which we identified evidence by updating two existing systematic literature searches. The GRADE (CERQual) methodology was used for appraisal of evidence. Furthermore, we searched for additional literature such as existing guidelines and textbooks to deal with lack of evidence. RESULTS: The two systematic literature searches yielded a total of 29 RCTs or systematic reviews of RCTs on paediatric palliative care interventions and 22 qualitative studies on barriers and facilitators of advance care planning and shared decision-making. We identified evidence for 14 out of 38 clinical questions. Furthermore, we were able to select additional literature (29 guidelines, two textbooks, and 10 systematic reviews) to deal with lack of evidence. CONCLUSIONS: The revised Dutch paediatric palliative care guideline addresses many topics. However, there is limited evidence to base recommendations upon. Our methodology will combine the existing evidence in scientific literature, additional literature, expert knowledge, and perspectives of patients and their families to provide recommendations.

Adults born prematurely prefer a periviability guideline that considers multiple prognostic factors beyond gestational age.

AIM: The aim of the study was to explore the perspectives of adults born prematurely on guidelines for management at extreme premature birth and personalisation at the limit of viability. METHODS: We conducted four 2-h online focus group interviews in the Netherlands. RESULTS: Twenty-three participants born prematurely were included in this study, ranging in age from 19 to 56 years and representing a variety of health outcomes. Participants shared their perspectives on different types of guidelines for managing extremely premature birth. They agreed that a guideline was necessary to prevent arbitrary treatment decisions and to avoid physician bias. All participants favoured a guideline that is based upon multiple prognostic factors beyond gestational age. They emphasised the importance of discretion, regardless of the type of guideline used. Discussions centred mainly on the heterogeneity of value judgements about outcomes after extreme premature birth. Participants defined personalisation as 'not just looking at numbers and statistics'. They associated personalisation mainly with information provision and decision-making. Participants stressed the importance of involving families in decision-making and taking their care needs seriously. CONCLUSION: Adults born prematurely prefer a periviability guideline that considers multiple prognostic factors and allows for discretion.

Neonatal euthanasia in the context of palliative and EoL care.

Neonatal deaths can be categorized in 5 modes along the dimension of intervention and physiology. This classification can be helpful to analyze the choices that can be made in end-of-life care in the NICU. In the Netherlands, neonatal euthanasia became an optional 6th mode of death since publication and legalization of the Groningen Protocol. This paper summarizes the history, legal status and ethical justification of the Groningen Protocol, and describes end-of-life practice in the subsequent years. Since the implementation of the Groningen Protocol, the practice of neonatal euthanasia has almost disappeared. Simultaneously, there has been spectacular growth in neonatal palliative care programs in the Netherlands. Is there still a need for this last-resort option?

Dutch professionals' discussion preferences with the parents of extremely premature infants varied, but the trend was towards shared decision-making.

AIM: We explored professionals' views on sharing decision-making with parents before and after an extremely preterm birth and what healthcare professionals considered severe outcomes. METHODS: A nationwide, multi-centre online survey was carried out among a wide range of perinatal healthcare professionals in the Netherlands from 4 November 2020 to 10 January 2021. The medical chairs of all nine Dutch Level III and IV perinatal centres helped to disseminate the survey link. RESULTS: We received 769 survey responses. Most respondents (53%) preferred to place equal emphasis on two treatment options during shared prenatal decision-making: early intensive care or palliative comfort care. The majority (61%) wanted to include a conditional intensive care trial as a third treatment option, but 25% disagreed. Most (78%) felt that healthcare professionals were responsible for initiating postnatal conversations to justify continuing or withdrawing neonatal intensive care if complications were associated with poor outcomes. Finally, 43% were satisfied with the current definitions of severe long-term outcomes, 41% were unsure and there were numerous for a broader definition. CONCLUSION: Although Dutch professionals expressed diverse preferences on how to reach decisions about extremely premature infants, we observed a trend towards shared decision-making with parents. These results could inform future guidelines.

Improvement and implementation of a national individual care plan in paediatric palliative care: a study protocol.

INTRODUCTION: Paediatric palliative care (PPC) is care for children with life-threatening or life-limiting conditions, and can involve complex high-tech care, which can last for months or years. In 2015, the National Individual Care Plan (ICP) for PPC was developed and has shown to be successful. The ICP can be seen as an instrument to facilitate coordination, quality and continuity of PPC. However, in practice, an ICP is often completed too late and for too few children. We aim to improve the coordination, quality and continuity of care for every child with a life-threatening or life-limiting condition and his/her family by further developing and implementing the ICP in the Netherlands. METHODS AND ANALYSIS: To evaluate the original ICP, ICP 1.0, interviews and questionnaires will be held among parents of children who have or have had an ICP 1.0 and healthcare professionals (HCPs) who used ICP 1.0. Based on the results, ICP 1.0 will be further developed. An implementation strategy will be written and the renewed ICP, ICP 2.0, will be nationally tested in an implementation period of approximately 7 months. During the implementation period, ICP 2.0 will be used for all children who are registered with Children's Palliative Care teams. After the implementation period, ICP 2.0 will be evaluated using interviews and questionnaires among parents of children who received ICP 2.0 and HPCs who worked with ICP 2.0. Based on these results, ICP 2.0 will be further optimised into the final version: ICP 3.0. ETHICS AND DISSEMINATION: This study received ethical approval. The ICP 3.0 will be disseminated through the Dutch Centre of Expertise in Children's Palliative Care, to ensure wide availability for the general public and HCPs within PPC. Additionally, we aim to publish study results in open-access, peer-reviewed journals and to present results at national and international scientific meetings.

Should the Dutch Law on Euthanasia Be Expanded to Include Children?

The 2002 Dutch Euthanasia law applies to patients aged 12 years and older. Developments in end-of-life care and decision-making in the last decade have sparked the debate about usefulness and necessity to extend euthanasia to include children under 12 years of age. This paper describes two opposite positions: the affirmative position of a pediatrician and expert in pediatric palliative care and the negative position of a jurist and specialist in health law.

Scaffold-based tissue engineering: Supercritical carbon dioxide as an alternative method for decellularization and sterilization of dense materials.

Development of ready-to-use biomaterials and scaffolds is vital for further advancement of scaffold-based tissue engineering in clinical practice. Scaffolds need to mimic 3D ultrastructure, have adequate mechanical strength, are biocompatible, non-immunogenic and need to promote tissue regeneration in vivo. Although decellularization of native tissues seems promising to deliver scaffolds that meet these criteria, adequate decellularization of hard, poorly penetrable and poorly diffusible tissues remains challenging whilst being a very time-consuming process. In this study, a method to decellularize hard, dense tissues using supercritical carbon-dioxide preceded by a freeze/thaw cycle and followed by several washing steps is presented, demonstrating decellularisation efficiency and substantially reduced production/handling time. Additionally, supercritical carbon-dioxide treatment was used as sterilization method, further reducing the time required to produce the final scaffold. Histological evaluation showed that, after fine-tuning of the process, a partially acellular scaffold was obtained, with preservation of glycosaminoglycans and collagen fibers, albeit that the amount of residual dsDNA was still higher then chemically decellularized tissue. Biomechanical properties of the scaffold were similar to the native, non-decellularized tissue. After sterilization with supercritical carbon-dioxide the simulated functional outcome was more similar to native trachea, when compared to sterilization using gamma irradiation. Thus, decellularization and sterilization using supercritical carbon-dioxide with washing steps is an effective method for dense cartilaginous materials, and tuneable to meet different demands in other applications, but further optimization may be required. STATEMENT OF SIGNIFICANCE: Further advancement of the use of tissue engineered tracheal constructs is restricted by the lack of the ideal scaffold. Decellularized trachea is considered a promising scaffold, but the hard, poorly diffusible tissue remains challenging while forming a very time consumable process. Decellularization using supercritical carbon dioxide (scCO2) seems promising, resulting in efficient removal of cellular material while reducing production and handling time. Addition of scCO2 as a sterilization method resulted in further time reduction while improving functional outcome in comparison with traditional sterilization methods. This study presents an promising alternative method for decellularization and sterilization of dense materials, which can be tuned to meet different demands in other applications.

The age limit for euthanasia requests in the Netherlands: a Delphi study among paediatric experts.

BACKGROUND: The Dutch Euthanasia Act applies to patients 12 years and older, which makes euthanasia for minors younger than 12 legally impossible. The issue under discussion specifically regards the capacity of minors to request euthanasia. OBJECTIVE: Gain insight in paediatric experts' views about which criteria are important to assess capacity, from what age minors can meet those criteria, what an assessment procedure should look like and what role parents should have. METHODS: A Delphi study with 16 experts (paediatricians, paediatric nurses and paediatric psychologists) who work in Children Comfort Teams in Dutch academic hospitals. The questionnaire contained statements concerning criteria for capacity and procedural criteria. Consensus was defined as ≥80% agreement. RESULTS: The experts agreed that five criteria for capacity, found in a previous literature study, are all important. They agreed that some children between ages 9 and 11 could meet all the criteria. Consensus was reached for the statements that the entire medical team should be involved in the decision making and that a second independent expert must assess the case. Experts agreed that the parents' opinion is relevant and should always be taken into account, but it need not be decisive. CONCLUSION: This study shows that the age limit of 12 years in the Dutch Euthanasia Act is too strong according to paediatric experts. Letting go of the age limit or lowering the age limit combined with adequate capacity assessment for minors younger than 12 are options that should be discussed further.

Optimal postoperative pain management after VATS lung resection by thoracic epidural analgesia, continuous paravertebral block or single-shot intercostal nerve block (OPtriAL): study protocol of a three-arm multicentre randomised controlled trial.

BACKGROUND: Adequate pain control after video-assisted thoracoscopic surgery (VATS) for lung resection is important to improve postoperative mobilisation, recovery, and to prevent pulmonary complications. So far, no consensus exists on optimal postoperative pain management after VATS anatomic lung resection. Thoracic epidural analgesia (TEA) is the reference standard for postoperative pain management following VATS. Although the analgesic effect of TEA is clear, it is associated with patient immobilisation, bladder dysfunction and hypotension which may result in delayed recovery and longer hospitalisation. These disadvantages of TEA initiated the development of unilateral regional techniques for pain management. The most frequently used techniques are continuous paravertebral block (PVB) and single-shot intercostal nerve block (ICNB). We hypothesize that using either PVB or ICNB is non-inferior to TEA regarding postoperative pain and superior regarding quality of recovery (QoR). Signifying faster postoperative mobilisation, reduced morbidity and shorter hospitalisation, these techniques may therefore reduce health care costs and improve patient satisfaction. METHODS: This multi-centre randomised study is a three-arm clinical trial comparing PVB, ICNB and TEA in a 1:1:1 ratio for pain (non-inferiority) and QoR (superiority) in 450 adult patients undergoing VATS anatomic lung resection. Patients will not be eligible for inclusion in case of contraindications for TEA, PVB or ICNB, chronic opioid use or if the lung surgeon estimates a high probability that the operation will be performed by thoracotomy. PRIMARY OUTCOMES: (1) the proportion of pain scores ≥ 4 as assessed by the numerical rating scale (NRS) measured during postoperative days (POD) 0-2; and (2) the QoR measured with the QoR-15 questionnaire on POD 1 and 2. Secondary outcome measures are cumulative use of opioids and analgesics, postoperative complications, hospitalisation, patient satisfaction and degree of mobility. DISCUSSION: The results of this trial will impact international guidelines with respect to perioperative care optimization after anatomic lung resection performed through VATS, and will determine the most cost-effective pain strategy and may reduce variability in postoperative pain management. Trial registration The trial is registered at the Netherlands Trial Register (NTR) on February 1st, 2021 (NL9243). The NTR is no longer available since June 24th, 2022 and therefore a revised protocol has been registered at ClinicalTrials.gov on August 5th, 2022 (NCT05491239). PROTOCOL VERSION: version 3 (date 06-05-2022), ethical approval through an amendment (see ethical proof in the Study protocol proof).

The Bio Economic Seaweed Model (BESeM) for modelling tropical seaweed cultivation - experimentation and modelling.

The Bio Economic Seaweed Model (BESeM) is a model designed for modelling tropical seaweed cultivation. BESeM can simulate the common tropical seaweed cultivation system with multiple harvests per year, clonal reproduction and labour intensive harvesting and replanting activities. Biomass growth is modelled as a sigmoid, with growth being initially exponentially and eventually flattening off towards a maximum weight per plant or per square meter (w f,max ). To estimate the latter, longer duration experiments than normal are needed - in the order of 100 days rather than 45 days. Drying (on platforms on the beach) is simulated as well as increase in harvested chemical concentration over time since planting, for harvested chemicals such as agar extracted from Gracilaria or carrageenan extracted from Kappaphycus or Euchema. BESeM has a limited number of parameters which makes it easily amenable to new sites and species. An experiment is presented for a site in Indonesia in which Gracilaria was monitored for 120 days in 6 nearby sites and from which BESeM model parameters were estimated. A simulation example is presented which illustrates how BESeM can be used to find the optimum combination of replanting weight and harvest cycle length (in days) for maximising gross and net farm income.

Intestinal Oxygenation and Survival After Surgery for Necrotizing Enterocolitis: An Observational Cohort Study.

OBJECTIVE: To assess whether regional intestinal oxygen saturation (rintSO2) and regional cerebral oxygen saturation (rcSO2) measurements aid in estimating survival of preterm infants after surgery for NEC. SUMMARY OF BACKGROUND DATA: Predicting survival after surgery for NEC is difficult yet of the utmost importance for counseling parents. METHODS: We retrospectively studied prospectively collected data of preterm infants with surgical NEC who had available rintSO2 and rcSO2 values measured via near-infrared spectroscopy 0-24 hours preoperatively. We calculated mean rintSO2 and rcSO2 for 60-120 minutes for each infant. We analyzed whether preoperative rintSO2 and rcSO2 differed between survivors and non-survivors, determined cut-off points, and assessed the added value to clinical variables. RESULTS: We included 22 infants, median gestational age 26.9 weeks [interquartile range (IQR): 26.3-28.4], median birth weight 1088 g [IQR: 730-1178]. Eleven infants died postoperatively. Preoperative rintSO2, but not rcSO2, was higher in survivors than in non-survivors [median: 63% (IQR: 42-68) vs 29% (IQR: 21-43), P < 0.01), with odds ratio for survival 4.1 (95% confidence interval, 1.2-13.9, P = 0.02) per 10% higher rintSO2. All infants with rintSO2 values of >53% survived, whereas all infants with rintSO2 <35% died. Median C-reactive protein [138 mg/L (IQR: 83-179) vs 73 mg/L (IQR: 12-98), P < 0.01), lactate [1.1 mmol/L (IQR: 1.0-1.6) vs 4.6 mmol/L (IQR: 2.8-8.0), P < 0.01], and fraction of inspired oxygen [25% (IQR: 21-31) vs 42% (IQR: 30-80), P < 0.01] differed between survivors and non-survivors. Only rintSO2 remained significant in the multiple regression model. CONCLUSIONS: Measuring rintSO2, but not rcSO2, seems of added value to clinical variables in estimating survival of preterm infants after surgery for NEC. This may help clinicians in deciding whether surgery is feasible and to better counsel parents about their infants' chances of survival.
