Multiomics, artificial intelligence, and precision medicine in perinatology.

Technological advances in omics evaluation, bioinformatics, and artificial intelligence have made us rethink ways to improve patient outcomes. Collective quantification and characterization of biological data including genomics, epigenomics, metabolomics, and proteomics is now feasible at low cost with rapid turnover. Significant advances in the integration methods of these multiomics data sets by machine learning promise us a holistic view of disease pathogenesis and yield biomarkers for disease diagnosis and prognosis. Using machine learning tools and algorithms, it is possible to integrate multiomics data with clinical information to develop predictive models that identify risk before the condition is clinically apparent, thus facilitating early interventions to improve the health trajectories of the patients. In this review, we intend to update the readers on the recent developments related to the use of artificial intelligence in integrating multiomic and clinical data sets in the field of perinatology, focusing on neonatal intensive care and the opportunities for precision medicine. We intend to briefly discuss the potential negative societal and ethical consequences of using artificial intelligence in healthcare. We are poised for a new era in medicine where computational analysis of biological and clinical data sets will make precision medicine a reality. IMPACT: Biotechnological advances have made multiomic evaluations feasible and integration of multiomics data may provide a holistic view of disease pathophysiology. Artificial Intelligence and machine learning tools are being increasingly used in healthcare for diagnosis, prognostication, and outcome predictions. Leveraging artificial intelligence and machine learning tools for integration of multiomics and clinical data will pave the way for precision medicine in perinatology.

Recommendations to improve recruitment and retention of underrepresented in medicine trainees in neonatal-perinatal medicine.

Physicians who identify as Black, Latinx, American Indian, Pacific Islander, and certain Asian subgroups represent racial and ethnic populations that are underrepresented in medicine (URM). While the proportion of URM pediatric trainees has remained unchanged, that of Neonatal-Perinatal Medicine (NPM) fellows has decreased. Informed by the medical literature and our lived experiences, we compiled and developed a list of recommendations to support NPM fellowship programs in the recruitment, retention, and promotion of URM trainees. We describe ten recommendations that address 1) creating a culture of inclusivity and psychological safety, 2) the critical appraisal of recruitment practices and climate, and 3) an inclusive and holistic fellowship application process. The first two themes lay the foundation, while the final theme spotlights our recommendations for URM recruitment. Each recommendation is a step towards improvement in recruitment and inclusion at a program.

Percepção sobre o cuidado à perda gestacional: estudo qualitativo com casais brasileiros / Perceptions on pregnancy loss care: a qualitative study with brazilian couples / Percepción sobre la atención a la pérdida del embarazo: estudio cualitativo con parejas brasileñas

Este artigo analisou a percepção e os sentimentos de casais sobre o atendimento recebido nos serviços de saúde acessados em função de perda gestacional (óbito fetal ante e intraparto). O convite para a pesquisa foi divulgado em mídias sociais (Instagram e Facebook). Dos 66 casais que contataram a equipe, 12 participaram do estudo, cuja coleta de dados ocorreu em 2018. Os casais responderam conjuntamente a uma ficha de dados sociodemográficos e uma entrevista semiestruturada, realizada presencialmente (n=4) ou por videochamada (n=8). Os dados foram gravados em áudio e posteriormente transcritos. A Análise Temática indutiva das entrevistas identificou cinco temas: sentimento de impotência, iatrogenia vivida nos serviços, falta de cuidado em saúde mental, não reconhecimento da perda como evento com consequências emocionais negativas, e características do bom atendimento. Os achados demonstraram situações de violência, comunicação deficitária, desvalorização das perdas precoces, falta de suporte para contato com o bebê falecido e rotinas pouco humanizadas, especialmente durante a internação após a perda. Para aprimorar a assistência às famílias enlutadas, sugere-se qualificação profissional, ampliação da visibilidade do tema entre diferentes atores e reorganização dos serviços, considerando uma diretriz clínica para atenção ao luto perinatal, com destaque para o fortalecimento da inserção de equipes de saúde mental no contexto hospitalar.(AU)

This study analyzed couples' perceptions and feelings about pregnancy loss care (ante and intrapartum fetal death). A research invitation was published on social media (Instagram and Facebook) and data collection took place in 2018. Of the 66 couples who contacted the research team, 12 participated in the study by filling a sociodemographic questionnaire and answering a semi-structured interview in person (n=04) or by video call (n=08). All interviews were audio recorded, transcribed, and examined by Inductive Thematic Analysis, which identified five themes: feelings of impotence, iatrogenic experiences in health services, lack of mental health care, not recognizing pregnancy loss as an emotionally overwhelming event, and aspects of good healthcare. Analysis showed experiences of violence, poor communication, devaluation of early losses, lack of support for contact with the deceased baby, and dehumanizing routines, especially during hospitalization after loss. Professional qualification, extended pregnancy loss visibility among different stakeholders, and reorganization of health services are needed to improve the care offered to grieving families, considering a clinical guideline for perinatal grief care with emphasis on strengthening the insertion of mental health teams in the hospital context.(AU)

[Perinatal beliefs: Neurocognitive mechanisms and cultural specificities]. / Croyances périnatales : mécanismes neurocognitifs et spécificités culturelles.

Perinatal beliefs contribute to the experience of pregnancy and the process of parenthood. Many of these perinatal beliefs have been perpetuated and evolved over time and throughout the world, exerting their influence on the behavior of pregnant women in interaction with medical recommendations. These beliefs generally offer explanations for gravidic and puerperal phenomena, helping to reduce the uncertainty of parents faced with the biological, psychological and social transitions of pregnancy. But certain beliefs can also be harmful, and alter the maternal experience of pregnancy and postpartum. In this paper, we provide an overview of the beliefs associated with the perinatal period. We successively detail the beliefs concerning fertility, pregnancy, childbirth, and postpartum, specifying the cultural beliefs from other cultures interacting with medical recommendations. Finally, we propose a neurocognitive model of perinatal beliefs generation, and we show the need to know these beliefs to improve care in midwifery, obstetrics, and fetal medicine.

Performance of Fetal Medicine Foundation algorithm for first trimester preeclampsia screening in an indigenous south Asian population.

BACKGROUND: To evaluate the performance of the Fetal Medicine Foundation (FMF) preterm preeclampsia (PE) screening algorithm in an indigenous South Asian population. METHODS: This was a prospective observational cohort study conducted in a tertiary maternal fetal unit in Delhi, India over 2 years. The study population comprised of 1863 women carrying a singleton pregnancy and of South Asian ethnicity who were screened for preterm pre-eclampsia (PE) between 11 and 14 weeks of gestation using Mean Arterial Pressure (MAP), transvaginal Mean Uterine Artery Pulsatility Index (UtAPI) and biochemical markers - Pregnancy Associated Plasma Protein-A (PAPP-A) and Placental Growth Factor.. Absolutemeasurements of noted biomarkers were converted to multiples of the expected gestational median (MoMS) which were then used to estimate risk for preterm PE < 37 weeks using Astraia software. Women with preterm PE risk of ≥1:100 was classified as as high risk. Detection rates (DR) at 10% false positive rate were calculated after adjusting for prophylactic aspirin use (either 75 or 150 mg). RESULTS: The incidence of PE and preterm PE were 3.17% (59/1863) and 1.34% (25/1863) respectively. PAPP-A and PlGF MoM distribution medians were 0.86 and 0.87 MoM and significantly deviated from 1 MoM. 431 (23.1%) women had a risk of ≥1:100, 75 (17.8%) of who received aspirin. Unadjusted DR using ≥1:100 threshold was 76%.Estimated DRs for a fixed 10% FPR ranged from 52.5 to 80% depending on biomarker combination after recentering MoMs and adjusting for aspirin use. CONCLUSION: The FMF algorithm whilst performing satisfactorily could still be further improved to ensure that biophysical and biochemical markers are correctly adjusted for indigenous South Asian women.

Prenatal ultrasound diagnosis of neural tube defects in the era of intrauterine repair - Eleven years' experiences.

OBJECTIVE: To modify the current neural tube defect (NTD) classification for fetal medicine specialists, and to investigate the impact of prenatal ultrasound conus medullaris position screening on the detection rate of closed spinal dysraphism and pregnancy outcomes. MATERIALS AND METHODS: The clinical data of 112 patients prenatally diagnosed with neural tube defects in Taiji clinic from 2008 to 2018 were retrospectively analyzed. All cases were classified following the modified classification. We compared the detection rate before and after introducing the conus medullaris screening and pregnancy outcomes for NTD types. RESULTS: Closed spinal dysraphism type prevailed in our sample (43.8%). The median gestational age at the time of detection for cranial dysraphism was 13.3 weeks, open spinal dysraphism was 22.0 weeks, and closed spinal dysraphism was 22.6 weeks. All cranial dysraphism (n = 43) and open spinal dysraphism cases (n = 20) had pregnancies terminated. For closed spinal dysraphism Class 1, the live-birth rate was 100.0% in the cases without other anomalies and 33.3% in the cases with other anomalies, respectively (X2 = 17.25, p < 0.001). Similarly, for Class 2, pregnancy continuation rate was 50.0% in cases without other anomalies and 20.0% in cases with other anomalies, yet it failed to reach statistical significance (X2 = 0.9, p = 0.524). CONCLUSION: Our case series may help to improve early screening and prenatal diagnosis of NTDs. Modified classification is adjusted for use in ultrasound fetal care facilities, which could be used for predicting pregnancy outcome. We suggest promoting first-trimester anatomical screening in order to make an earlier diagnosis and therefore provide better prenatal care for open spinal dysraphism cases in the era of intrauterine repair. Our findings imply that the use of fetal conus medullaris position as a marker for closed spinal dysraphism improves the detection rate and would unlikely lead to a higher termination rate.

Fetal medicine specialist experiences of providing a new service of termination of pregnancy for fatal fetal anomaly: a qualitative study.

OBJECTIVE: To explore fetal medicine specialists' experiences of caring for parents following a diagnosis of fatal fetal anomaly (FFA) during the implementation of termination of pregnancy (TOP) for FFA for the first time. DESIGN: Qualitative study. SETTING: Fetal medicine units in the Republic of Ireland. POPULATION: Ten fetal medicine specialists from five of the six fetal medicine units. METHODS: nvivo 12 assisted in the thematic analysis of semi-structured in-depth face-to-face interviews. MAIN OUTCOME MEASURES: Fetal medicine specialists' experiences of prenatal diagnosis and holistic management of pregnancies complicated by FFA. RESULTS: Four themes were identified: 'not fatal enough', 'interactions with colleagues', 'supporting pregnant women' and 'internal conflict and emotional challenges'. Fetal medicine specialists feared getting an FFA diagnosis incorrect because of media scrutiny and criminal liability associated with the TOP for FFA legislation. Challenges with the ambiguous and 'restrictive' legislation were identified that 'ostracised' severe anomalies. Teamwork was essential to facilitate opportunities for learning and peer support; however, conflict with colleagues was experienced regarding the diagnosis of FFA, the provision of feticide and palliative care to infants born alive following TOP for FFA. Participants reported challenges implementing TOP for FFA, including the absence of institutional support and 'stretched' resources. Fetal medicine specialists experienced internal conflict and a psychological burden providing TOP for FFA, but did so to 'provide full care for women'. CONCLUSIONS: Our study identified challenges regarding the suitability of the Irish legislation for TOP for FFA and its rapid introduction into clinical practice. It illustrates the importance of institutional and peer support, as well as the need for supportive management, in the provision of a new service. TWEETABLE ABSTRACT: The implementation of termination services for fatal fetal anomaly is complex and requires institutional support.

Announcing fetal pathology: Challenges encountered by physicians and potential role of simulation in training for breaking bad news.

BACKGROUND: Informing couples about the diagnosis of severe fetal pathologies is part of the daily routine in fetal medicine. This situation is usually complex and can put untrained professionals in an uncomfortable position. The aim of this study was to assess the perception of health care professionals when faced with the need to announce a fetal pathology in order to target their training gaps in this domain. MATERIALS AND METHODS: A questionnaire was created and disseminated on a national level among physicians practicing or collaborating with the multidisciplinary centers of prenatal diagnosis in France. The questionnaire focused on the difficulties encountered by practitioners when announcing fetal pathologies, and their potential interest in simulation sessions regarding the delivery of bad news. RESULTS: 193 participants filled the questionnaire. 65 % report not receiving any theoretical courses in this field during their initial training, 49 % admit feeling uncomfortable when a fetal anomaly needs to be announced, 79.5 % think that role-play could help them, 87.5 % believe that training sessions in communication skills would help improve their methods and 73.1 % support teaching the delivery of bad news by simulation sessions. CONCLUSION: This survey illustrates the significance of announcing a fetal pathology for fetal medicine professionals. Many of them report not being properly trained to cope with this situation and would like to improve with a more practical way of teaching. Simulation would be the ideal educational tool to meet this demand.

Educational Perspectives: Palliative Care Education in Neonatal-Perinatal Medicine Fellowship.

The neonatal period from birth to less than or equal to 28 days is one of increased risk of death. Congenital anomalies and prematurity are 2 of the most common risk factors for death at this early age. Many of these neonates will die in an intensive care unit, some with full resuscitative efforts being undertaken despite the understanding that these actions are highly unlikely to yield an outcome different from death. Palliative care allows curative therapies to be provided alongside supportive techniques such as enhanced family communication, attention to spirituality and the psychosocial health of the family, management of symptoms other than those specific to the underlying disease process, and enhancing comfort. The American Academy of Pediatrics has set forth recommendations related to pediatric palliative care for the various pediatric subspecialties; however, much of the focus is on disease processes and curing or mitigating various illnesses. Given the high preponderance of death in the neonatal period, neonatal-perinatal medicine training programs should be tasked with generating formal palliative care training. Such training should be geared to providing better care for neonatal patients with a life-limiting or life-altering illness, and better equipping future neonatologists with the tools needed to provide truly comprehensive care for their sickest patients at risk for death and disability. This article serves to review the concept of palliative care in neonates, discuss the paucity of formal education in palliative care, explore the general trend in palliative care education, review various ways in which palliative care education can be formalized, and define metrics of a successful educational program.

Scaling-up impact in perinatology through systems science: Bridging the collaboration and translational divides in cross-disciplinary research and public policy.

Despite progress over the past decade in reducing the global burden of newborn deaths, gaps in the knowledge base persist, and means of translating empirical findings into effective policies and programs that deliver life-saving interventions remain poorly understood. Articles in this issue highlight the relevance of transdisciplinary research in perinatology and calls for increased efforts to translate research into public policy and to integrate interventions into existing primary care delivery systems. Given the complexity and multi-causality of many of the remaining challenges in newborn health, and the effects that social and economic factors have over many newborn conditions, it has further been proposed that integrated, multi-sector public policies are also required. In this article, we discuss the application of systems science methods to advance transdisciplinary research and public policy-making in perinatology. Such approaches to research and public policy have been used to address various global challenges but have rarely been implemented in developing country settings. We propose that they hold great promise to improve not only our understanding of complex perinatology problems but can also help translate research-based insights into effective, multi-pronged solutions that deliver positive, intended effects. Examples of successful transdisciplinary science exist, but successes and failures are context specific, and there are no universal blueprints or formulae to reproduce what works in a specific context into different social system settings. Group model building is a tool, based in the field of System Dynamics, that we have used to facilitate transdisciplinary research and, to a lesser extent, policy formulation in a systematic and replicable way. In this article, we describe how group model building can be used and argue for scaling its use to further the translation of empirical evidence and insights into policy and action that increase maternal and neonatal survival and well-being.

Developmental effects of ghrelin.

Ghrelin is a pleiotropic hormone that was originally described as promoting feeding and stimulating growth hormone release in adults. A growing body of evidence suggests that ghrelin may also exert developmental and organizational effects during perinatal life. The perinatal actions of ghrelin include the regulation of early developmental events such as blastocyst development and perinatal growth. Moreover, alterations in perinatal ghrelin levels result in structural differences in various peripheral organs, such as the pancreas and gastrointestinal tract. Recent data have also suggested that ghrelin acts on appetite-related brain centers in early life. Together, these observations indicate that exposure to factors that alter how ghrelin impacts development may induce lasting effects on physiological regulation.

Critical illness during pregnancy: considerations for evaluation and treatment of the fetus as the second patient.

When a critically ill woman is pregnant, clinical interventions for the mother can have a profound effect on fetal status. It is essential that the fetus be considered as the second patient when developing the plan of care. The most practical solution for providing comprehensive care to pregnant women in the intensive care unit (ICU) is a collaborative approach involving members of the ICU and the perinatal team, each contributing their unique knowledge and skills to the care of the mother and her unborn baby. The purpose of this article is to describe a collaborative approach to caring for a pregnant woman in the ICU along with a brief overview of fetal assessment for ICU care providers so they can become familiar with terms and methods used in assessing fetal status and common interventions that promote fetal well-being.

Incidencia e intensidad de la hiperbilirrubinemia y anemia en neonatos con incompatibilidad ABO / Incidence and intensity of hiperbilirubinemia and anemia in newborns with ABO incompatibility

La asociación entre la incompatibilidad ABO, anemia e hiperbilirrubinemia, es bien conocida en la población de recién nacidos. El presente estudio es de tipo clínico prospectivo y fue realizado en el Hospital General del Oeste en Caracas, Venezuela desde abril de 2002 hasta julio de 2003. Se seleccionaron 50 pacientes de una población total de 6543 recién nacidos, los cuales reunían los criterios de inclusión para el estudio. Los pacientes fueron divididos en tres grupos: asintomático, con enfermedad hemolítica moderada y con enfermedad hemolítica severa. La evaluación clínica y las mediciones hematológicas fueron determinadas en los próximos tres meses de seguimiento. La evaluación estadística incluyo calculo de las medias, desviación Standard y T de student. La incidencia de incompatibilidad ABO fue de 7.64 por 1000 nacidos vivos; enfermedad hemolítica severa, 1,22 x 1000 nacidos vivos, enfermedad hemolítica moderada, 4,89 x 1000 nacidos vivos e incompatibilidad ABO asintomática, 1,53 x 1000 nacidos vivos. En el grupo enfermedad hemolítica severa, 37,5% fue incluido en el subgrupo OA, y 62,5% en el subgrupo OB. La ictericia como hallazgo clínico estuvo presente en 40 pacientes (80,6%), y como manifestación clínica inicial sólo fue evidente en 17 pacientes (34%). Todos los pacientes con ictericia recibieron fototerapia y 5 (10%) ameritaron exanguinotransfusión. Fue necesario transfundir a 4 pacientes (8%). No se encontró diferencia estadísticamente significativa entre los grupos masculino y femenino. La incompatibilidad ABO es una patología neonatal frecuente en nuestro medio, se observa con más frecuencia, la hemólisis moderada y la ictericia precoz que constituyen en el clínico principal.

Integration challenges of clinical information systems developed without a shared data dictionary.

Legacy systems have proven to be long-term integration challenges for Intermountain Health Care (IHC) despite commitment and attention to share clinical information across settings and among clinicians. This study measures the extent of the disparity of data elements across three independent data systems in current use. A sample of relevant data elements was selected across systems covering prenatal, labor and delivery, and newborn intensive care units (NICU). The findings revealed only 17% of these sample data elements had compatible structure across all three systems. The implications from differences in granularity, missing data, and duplicate data entry, include diminished data quality, greater risk for medical error, increased costs of integration and inefficient use of clinician time. Retrospective guidelines for managing conceptual context and granularity are given to assist in designing an integrated longitudinal patient electronic medical record.

Effect of administering recombinant erythropoietin to women with postpartum anemia: a meta-analysis.

OBJECTIVES: Recombinant erythropoietin (rEpo) has been administered to women with postpartum anemia in an attempt to accelerate their increase in hemoglobin concentration and reduce postpartum transfusions. However, it is not clear whether such an approach can be supported by evidence and should be generally recommended. STUDY DESIGN AND METHODS: Medical and scientific literature from January 1990 to December 2002 was searched and studies that reported the administration of rEpo to women with postpartum anemia were evaluated. RESULTS: Eight evaluated studies reported an aggregate of 480 women; 300 rEpo recipients and 180 controls. Significant diversity in design was observed in rEpo dose, route of rEpo administration, iron supplementation, and baseline hemoglobin. No significant safety concerns were reported. In all five studies where it was reported, 4 to 7 days after beginning treatment, greater increases in hemoglobin concentration were observed among the rEpo recipients than among the controls. However, heterogeneity of results (Q-test statistic, p<0.01) indicated that it was not appropriate to apply summary statistics. The effect of rEpo on postpartum transfusion rate was not measurable by summary statistics because of the limited number of transfusions given (no transfusions among the 300 rEpo recipients vs two transfusions among the 180 controls). CONCLUSION: Administration of rEpo to women with postpartum anemia appears to be safe, and is associated with a trend toward a faster increase in hemoglobin concentration. However, its efficacy in terms of diminishing postpartum transfusions is unproven.
