Objective: To identify parents' information needs about impending very preterm birth and compare these needs to current information practices in the Netherlands. Methods: Step 1: We surveyed N = 203 parents of preterm infants to assess their information needs. Data were analyzed using inductive thematic analysis. Step 2a: We collected information resources from hospitals (N = 9 NICUs) and via an online search. These materials were analyzed using deductive thematic analysis. Step 2b: We compared findings from Steps 1-2a. Results: We identified four themes pertaining to parents' information needs: (1) participation in care, (2) emotional wellbeing, (3) experience/success stories, and (4) practical information about prematurity. Clinicians' communicative skills and time were considered prerequisites for optimal information-provision. Notably, hospital resources provided mainly medical information about prematurity with some emphasis on participation in care, while parent associations mainly focused on emotional wellbeing and experience/success stories. Conclusion: While parents demonstrate clear information needs about impending very preterm birth, current information resources satisfy these partially. Innovation: Our multidisciplinary research team included both scholars and veteran NICU parents. As such, we identified parents' information needs bottom-up. These parent-driven insights will be used to design an innovative, tailored information platform for parents about impending very preterm birth.

Predicting the short- and long-term outcomes of extremely preterm infants remains a challenge. Multivariable prognostic models might be valuable tools for clinicians, parents, and policymakers for providing accurate outcome estimates. In this perspective, we discuss the opportunities and challenges of using prognostic models in extremely preterm infants at population and individual levels. At a population level, these models could support the development of guidelines for decisions about treatment limits and may support policy processes such as benchmarking and resource allocation. At an individual level, these models may enhance prenatal counselling conversations by considering multiple variables and improving transparency about expected outcomes. Furthermore, they may improve consistency in projections shared with parents. For the development of prognostic models, we discuss important considerations such as predictor and outcome measure selection, clinical impact assessment, and generalizability. Lastly, future recommendations for developing and using prognostic models are suggested. Importantly, the purpose of a prognostic model should be clearly defined, and integrating these models into prenatal counselling requires thoughtful consideration.

Introduction Necrotising enterocolitis is a devastating gastrointestinal disease predominantly affecting preterm infants. In 40% of cases, its rapid progression renders conservative treatment insufficient, necessitating laparotomy as the sole viable option for survival. However, high perioperative and postoperative mortality rates, along with severe future potential disabilities and suffering, can complicate the decision of whether surgery is still in the infant’s best interest. In such cases, palliative care, aimed to minimise suffering, may be considered as an alternative to laparotomy, especially when the infant’s expected quality of life and overall prognosis are concerning. Depending on the sociocultural context, parents are increasingly involved in this decision. However, weighing the risks, benefits and uncertainties can be challenging for them. Therefore, we aim to develop a decision support tool using a novel combination of the Delphi technique and Q-methodology. Ultimately, we anticipate that this approach will contribute to improved family-centred care and optimised outcomes.Methods and analysis The first phase of the study aims to identify key factors guiding Dutch parents’ decisions between laparotomy and palliative care (decision factors). Using a Delphi process, parents with varying perspectives and experiences will evaluate decision factors found in the literature and those self-suggested. The pertinent set of decision factors is defined during a consensus meeting.During the second phase, parents are asked to compare statements about these decision factors using Q-methodology. A by-person factor analysis of these comparisons will identify different parental decision-making profiles, which allows for formulating advice tailored to those profiles.Ultimately, we will build an online decision support tool which facilitates the classification of parent perspectives. The tool will then provide the parents with the relevant advice. In the last phase of the study, the tool’s effectiveness will be evaluated through an online questionnaire, asking parents to imagine using the tool in a real-world scenario.Ethics and dissemination Ethical approval has been obtained from Central Ethics Review Committee of The University Medical Center Groningen (METc 2023/577, CTc UMCG 153660). Participants will be asked to provide their informed consent for the parts of the study that involve non-anonymous data gathering. Findings will be disseminated through academic journals and conferences. Options for long-term data preservation are under consideration.

BACKGROUND:Countries worldwide recommend women planning pregnancy to use daily 400 microg of synthetic folic acid in the periconceptional period to prevent birth defects in children. The underlying mechanisms of this preventive effect are not clear, however, epigenetic modulation of growth processes by folic acid is hypothesized. Here, we investigated whether periconceptional maternal folic acid use and markers of global DNA methylation potential (S-adenosylmethionine and S-adenosylhomocysteine blood levels) in mothers and children affect methylation of the insulin-like growth factor 2 gene differentially methylation region (IGF2 DMR) in the child. Moreover, we tested whether the methylation of the IGF2 DMR was independently associated with birth weight. METHODOLOGY/PRINCIPAL FINDINGS:IGF2 DMR methylation in 120 children aged 17 months (SD 0.3) of whom 86 mothers had used and 34 had not used folic acid periconceptionally were studied. Methylation was measured of 5 CpG dinucleotides covering the DMR using a mass spectrometry-based method. Children of mother who used folic acid had a 4.5% higher methylation of the IGF2 DMR than children who were not exposed to folic acid (49.5% vs. 47.4%; p = 0.014). IGF2 DMR methylation of the children also was associated with the S-adenosylmethionine blood level of the mother but not of the child (+1.7% methylation per SD S-adenosylmethionine; p = 0.037). Finally, we observed an inverse independent association between IGF2 DMR methylation and birth weight (-1.7% methylation per SD birthweight; p = 0.034). CONCLUSIONS:Periconceptional folic acid use is associated with epigenetic changes in IGF2 in the child that may affect intrauterine programming of growth and development with consequences for health and disease throughout life. These results indicate plasticity of IGF2 methylation by periconceptional folic acid use.

In this paper we present an initial roadmap for the ethical development and eventual implementation of artificial amniotic sac and placenta technology in clinical practice. We consider four elements of attention: (1) framing and societal dialogue; (2) value sensitive design, (3) research ethics and (4) ethical and legal research resulting in the development of an adequate moral and legal framework. Attention to all elements is a necessary requirement for ethically responsible development of this technology. The first element concerns the importance of framing and societal dialogue. This should involve all relevant stakeholders as well as the general public. We also identify the need to consider carefully the use of terminology and how this influences the understanding of the technology. Second, we elaborate on value sensitive design: the technology should be designed based upon the principles and values that emerge in the first step: societal dialogue. Third, research ethics deserves attention: for proceeding with first-in-human research with the technology, the process of recruiting and counseling eventual study participants and assuring their informed consent deserves careful attention. Fourth, ethical and legal research should concern the status of the subject in the AAPT. An eventual robust moral and legal framework for developing and implementing the technology in a research setting should combine all previous elements. With this roadmap, we emphasize the importance of stakeholder engagement throughout the process of developing and implementing the technology; this will contribute to ethically and responsibly innovating health care.

Introduction Twin pregnancies have a high risk of extreme preterm birth (PTB) at less than 28 weeks of gestation, which is associated with increased risk of neonatal morbidity and mortality. Currently there is a lack of effective treatments for women with a twin pregnancy and a short cervix or cervical dilatation. A possible effective surgical method to reduce extreme PTB in twin pregnancies with an asymptomatic short cervix or dilatation at midpregnancy is the placement of a vaginal cerclage.Methods and analysis We designed two multicentre randomised trials involving eight hospitals in the Netherlands (sites in other countries may be added at a later date). Women older than 16 years with a twin pregnancy at
