- Abstract
INTRODUCTION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) has become standard of care for patients with peritoneal metastases of colorectal origin with a low/moderate abdominal disease load. In case of a peritoneal cancer index (PCI) score >20, CRS-HIPEC is not considered to be beneficial. Patients with a PCI >20 are currently offered palliative systemic chemotherapy. Previous studies have shown that systemic chemotherapy is less effective against peritoneal metastases than it is against haematogenous spread of colorectal cancer. It is suggested that patients with peritoneal metastases may benefit from the addition of intraperitoneal chemotherapy to systemic chemotherapy. Aim of this study is to establish the maximum tolerated dose of intraperitoneal irinotecan, added to standard of care systemic therapy for colorectal cancer. Secondary endpoints are to determine the safety and feasibility of this treatment and to establish the pharmacokinetic profile of intraperitoneally administered irinotecan. METHODS AND ANALYSIS: This phase I, '3+3' dose-escalation, study is performed in two Dutch tertiary referral centres. The study population consists of adult pat

- Abstract
Background: Although compassion is a crucial element of physicians' professional performance and high-quality care, research shows it often remains an unmet need of patients. Understanding patients' and physicians' perspectives on compassionate care may provide insights that can be used to foster physicians' ability to respond to patients' compassion needs. Therefore, this study aims to understand how both patients and physicians experience the concept and practice of compassionate care., Methods: We conducted semi-structured interviews with eight patients and ten resident physicians at a University Medical Center in the Netherlands. Using thematic analysis, we separately coded patient and resident transcripts to identify themes capturing their experiences of compassionate care. This study was part of a larger project to develop an educational intervention to improve compassion in residents., Results: For both patients and residents, we identified four themes encompassing compassionate care: being there, empathizing, actions to relieve patients' suffering, and connection. For residents, a fifth theme was professional fulfillment (resulting from compassionate care). Although patients and residents both emphasized the importance of compassionate care, patients did not always perceive the physician-patient encounter as compassionate. According to residents, high workloads and time pressures hindered their ability to provide compassionate care., Discussion and Conclusion: Patients and residents have similar and varying understandings of compassionate care at the same time. Understanding these differences can aid compassion in medical practice. Based on the findings, three topics are suggested to improve compassion in residents: (1) train residents how to ask for patients' compassion needs, (2) address residents' limiting beliefs about the concept and practice of compassion, and (3) acknowledge the art and science of medicine cannot be separated., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Debets et al.

- Abstract
Background: Patients with colorectal peritoneal metastases who are not eligible for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) owing to extensive peritoneal disease have a poor prognosis. It was hypothesized that these patients may benefit from the addition of intraperitoneal irinotecan to standard palliative systemic chemotherapy., Methods: This was a classical 3 + 3 phase I dose-escalation trial in patients with colorectal peritoneal metastases who were not eligible for CRS-HIPEC. Intraperitoneal irinotecan was administered every 2 weeks, concomitantly with systemic FOLFOX (5-fluorouracil, folinic acid, oxaliplatin)-bevacizumab. The primary objective was to determine the maximum tolerated dose and dose-limiting toxicities. Secondary objectives were to elucidate the systemic and intraperitoneal pharmacokinetics, safety profile, and efficacy., Results: Eighteen patients were treated. No dose-limiting toxicities were observed with 50 mg (4 patients) and 75 mg (9 patients) intraperitoneal irinotecan. Two dose-limiting toxicities occurred with 100 mg irinotecan among five patients. The maximum tolerated dose of intraperitoneal irinotecan was established to be 75 mg, and it was well tolerated. Intraperitoneal exposure to SN-38 (active metabolite of irinotecan) was high compared with systemic exposure (median intraperitoneal area under the curve (AUC) to systemic AUC ratio 4.6). Thirteen patients had a partial radiological response and five had stable disease. Four patients showed a complete response during post-treatment diagnostic laparoscopy. Five patients underwent salvage resection or CRS-HIPEC. Median overall survival was 23.9 months., Conclusion: Administration of 75 mg intraperitoneal irinotecan concomitantly with systemic FOLFOX-bevacizumab was safe and well tolerated. Intraperitoneal SN-38 exposure was high and prolonged. As oncological outcomes were promising, intraperitoneal administration of irinotecan may be a good alternative to other, more invasive and costly treatment options. A phase II study is currently accruing., (© The Author(s) 2023. Published by Oxford University Press on behalf of BJS Society Ltd. All rights reserved.

- Abstract
Background: This article presents a set of quality characteristics of clinical ethics support (CES) in the Netherlands. Methods: The quality characteristics were developed with a large group of stakeholders working with CES, participating in the Dutch Network for Clinical Ethics Support (NEON). Results: The quality characteristics concern the following domains: (1) goals of CES, (2) methods of CES, (3) competences of CES practitioners, and (4) implementation of CES. Conclusions: We discuss suggestions for how to use the quality characteristics, discuss some aspects that stand out about these quality characteristics, and reflect on the method and the status of the quality characteristics. The quality characteristics are meant as a heuristic instrument, helping CES practitioners to explore and improve the quality of CES in a health care organization, but at the same time they can be improved based on experiences during their application to CES practices.

- Abstract
Objectives: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with postoperative gastroparesis and ileus. In 2015, our practice shifted from using percutaneous gastrostomy tubes (PGT), to nasogastric tubes (NGT) for prophylactic gastric decompression after CRS-HIPEC. This study aimed to compare these methods for length of stay (LOS) and associated complications., Methods: Patients that underwent CRS-HIPEC for peritoneal metastases from colorectal cancer between 2014 and 2019 were included. Cases were grouped based on receiving NGT or PGT postoperatively. Multivariable linear regression determined the independent effect of decompression method on LOS, thereby adjusting for confounders., Results: In total, 179 patients were included in the analyses. Median age was 64 years [IQR:54-71]. Altogether, 135 (75.4%) received a NGT and 44 (24.6%) received a PGT. Gastroparesis occurred significantly more often in the PGT group (18.2 vs. 7.4%, p=0.039). Median LOS was significantly shorter for patients with a NGT (15 [IQR:12-19] vs. 18.5 [IQR:17-25.5], p<0.001). PGT was independently associated with longer LOS in multivariable analysis (Beta=4.224 [95%CI 1.243-7.204]). There was no difference regarding aspiration, pneumonia and postoperative mortality between groups., Conclusions: NGT should be preferred over PGT for gastric decompression after CRS-HIPEC as it is associated with fewer gastroparesis and shorter LOS., Competing Interests: Competing interests: Authors state no conflict of interest., (© 2021 Job P. van Kooten et al., published by De Gruyter, Berlin/Boston.)

- Abstract
The aim of this research was to gain insight into the experiences and perspectives of individual members of a Medical Research Ethics Committee (MREC) regarding their individual roles and possible tensions within and between these roles. We conducted a qualitative interview study among members of a large MREC, supplemented by a focus group meeting. Respondents distinguish five roles: protector, facilitator, educator, advisor and assessor. Central to the role of protector is securing valid informed consent and a proper risk-benefit analysis. The role of facilitator implies that respondents want to think along with and assist researchers in order to help medical science progress. As educators, the respondents want to raise ethical and methodological awareness of researchers. The role of advisor implies that respondents bring in their own expertise. The role of assessor points to contributing to the overall evaluation of the research proposal. Various tensions were identified within and between roles. Within the role of protector, a tension is experienced between paternalism and autonomy. Between the role of protector and facilitator tensions occur when the value of a study is questioned while risks and burdens for the subjects are negligible. Within the role of assessor, a tension is felt between the implicit nature of judgments and the need for more explicit formulations. Awareness of various roles and responsibilities may prevent one-sided views on MREC work, not only by members themselves, but also by researchers. Tensions within and between the roles require reflection by MREC members.

Introduction: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) has become standard of care for patients with peritoneal metastases of colorectal origin with a low/moderate abdominal disease load. In case of a peritoneal cancer index (PCI) score >20, CRS-HIPEC is not considered to be beneficial. Patients with a PCI >20 are currently offered palliative systemic chemotherapy. Previous studies have shown that systemic chemotherapy is less effective against peritoneal metastases than it is against haematogenous spread of colorectal cancer. It is suggested that patients with peritoneal metastases may benefit from the addition of intraperitoneal chemotherapy to systemic chemotherapy. Aim of this study is to establish the maximum tolerated dose of intraperitoneal irinotecan, added to standard of care systemic therapy for colorectal cancer. Secondary endpoints are to determine the safety and feasibility of this treatment and to establish the pharmacokinetic profile of intraperitoneally administered irinotecan., Methods and Analysis: This phase I, '3+3' dose-escalation, study is performed in two Dutch tertiary referral centres. The study population consists of adult patients with extensive peritoneal metastases of colorectal origin who have a good performance status and no extra-abdominal metastases. According to standard work-up for CRS-HIPEC, patients will undergo a diagnostic laparoscopy to score the PCI. In case of a PCI >20, a peritoneal access port will be placed in the abdomen of the patient. Through this port we will administer intraperitoneal irinotecan, in combination with standard systemic treatment consisting of 5-fluorouracil/leucovorin with oxaliplatin and the targeted agent bevacizumab. Therapy consists of a maximum of 12 cycles 2-weekly., Ethics and Dissemination: This study protocol is approved by a research medical ethics committee (Rotterdam, Netherlands) and the Dutch Competent Authority (CCMO, The Hague, Netherlands). The results of this trial will be submitted for publication in a peer-reviewed scientific journal., Trail Registration Number: NL6988 and NL2018-000479-33; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Background: Studies showed that pregnant women generally value routine ultrasounds in the first two trimesters because these provide reassurance and a chance to see their unborn baby. This, in turn, might help to decrease maternal anxiety levels and increase the bond with the baby. However, it is unclear whether pregnant women hold the same positive views about a third trimester routine ultrasound, which is increasingly being used in the Netherlands as a screening tool to monitor fetal growth. The aim of this study was to explore pregnant women's experiences with a third trimester routine ultrasound., Methods: We held semi-structured interviews with fifteen low-risk pregnant women who received a third trimester routine ultrasound in the context of the Dutch IUGR RIsk Selection (IRIS) study. The IRIS study is a nationwide cluster randomized controlled trial carried out among more than 13,000 women to examine the effectiveness of a third trimester routine ultrasound to monitor fetal growth. For the interviews, participants were purposively selected based on parity, age, ethnicity, and educational level. We performed thematic content analysis using MAXQDA., Results: Most pregnant women appreciated a third trimester routine ultrasound because it provided them confirmation that their baby was fine and an extra opportunity to see their baby. At the same time they expressed that they already felt confident about the health of their baby, and did not feel that their bond with their baby had increased after the third trimester ultrasound. Women also reported that they were getting used to routine ultrasounds throughout their pregnancy, and that this increased their need for another one., Conclusions: Pregnant women seem to appreciate a third trimester routine ultrasound, but it does not seem to reduce anxiety or to improve bonding with their baby. Women's appreciation of a third trimester routine ultrasound might arise from getting used to routine ultrasounds throughout pregnancy. We recommend to examine the psychological impact of third trimester routine ultrasounds in future studies. Results should be taken into consideration when balancing the gains, which are as yet not clear, of introducing a third trimester routine ultrasound against unwanted side effects and costs.
