Fetal Death

Birthweight below the 10th (small for gestational age or SGA) or above the 90th (large for gestational age or LGA) percentile for gestational age has been associated with adverse maternal, fetal and neonatal outcomes. As birthweight reflects intrauterine development, accurate identification of abnormal fetal growth would allow obstetric providers to prevent adverse outcomes and mitigate complications associated with abnormal development. Symphysis fundal height (SFH) measured in centimeters after 24 weeks of gestation is recommended as the standard of care to screen for fetal growth abnormalities among low-risk pregnancies. This method is low-cost, and easy to perform, but there is a lack of evidence supporting its effectiveness due to its poor sensitivity. Ultrasonography, the technique utilized to identify fetal growth abnormalities, is a costly procedure which involves the use of advanced equipment and providers, to perform and review the ultrasound, as well as a full examination with multiple measurements and images. Despite a few encouraging reports, insufficient evidence supports routine 3rd trimester ultrasound in low- risk pregnancies to improve detection of abnormal fetal growth. Sonographic measurement of the abdominal circumference (AC) in the fetus was shown to be the single most useful indicator of fetal growth. Measurement of AC does not require extensive training, long time to acquire, or expensive ultrasound machines. It can be easily performed in the office by midwives who are specifically trained in obtaining the measurement. Therefore, we intended to evaluate if the use of bedside point of care ultrasound (POC-US) by midwives to evaluate fetal AC during routine antenatal visits in low-risk pregnancies would increase the accuracy of SFH in identifying fetuses with birthweight \< 10th or \> 90th, when compared to SFH alone. This is an open label, investigator sponsored, two arms randomized controlled trial. Patients who satisfy all inclusion criteria, have no exclusion criteria, and have signed the written informed consent will be randomly assigned to screening of fetal growth abnormalities during routine antenatal appointments held by midwives according to SFH or SFH + POC-US-AC. Low risk pregnant women are interviewed by a midwife at 35-38 weeks' gestation, who also reviews their medical and obstetrical history, prenatal labs and the ultrasound reports to discriminate between high and low-risk pregnancies. Patients who satisfy all inclusion criteria and do not have any exclusion criteria will be randomly assigned to one of two different approaches to identify fetal growth abnormalities and predict abnormal birthweight, after signing the written informed consent. Screening test in the control group: Symphysis fundal height measurement. Fundal height is measured by trained midwives at each scheduled antenatal appointment from the pubis symphysis to the top of the uterine fundus, using a paper measuring tape in centimeters. Size greater than dates is suspected if the measurement is above the 90th gestational age specific percentile according to the Intergrowth 21 SFH references (Papageorghiu 2016). Similarly, size less than dates is recorded if the measurement is below the 10th percentile for age according to the Intergrowth 21 SFH references (Papageorghiu 2016). Formal obstetric ultrasound is requested if the SFH is \> 90th percentile, if it is \< 10th , or if it drops 50 growth centiles in two subsequent evaluations. Screening test in the intervention group: Symphysis fundal height measurement + point of care ultrasound. After assessing SFH at each clinical encounter, the midwife will perform a POC-US to measure the fetal AC and evaluate the quantity of amniotic fluid. A positive screen for fetal growth restriction (indicative of a potential SGA infant) consists in a measured AC less than the 10th percentile for gestational age according to the standards defined by Nicolini et al in 1986 on an Italian population; instead, a positive screen for macrosomia (suggestive of a potential LGA infant) is an AC greater than the 90th percentile for gestational age according to the references set by Nicolini et al in 1996. Formal obstetric ultrasound is requested if the AC is \> 90th percentile, if it is \< 10th, or if it drops 50 growth centiles in two subsequent evaluations. Amniotic fluid volume will be evaluated determining the deepest vertical pocket (DVP). A formal US is requested in case uterine size is measured as ≤ than the 10th or ≥ than the 90th percentile for gestational age according to Intergrowth 21, when POC - US reveals AC \< 10th percentile, AC \> 90th percentile according to Nicolini et al, in case DVP \< 2 x 1 cm, or DVP \> 8 x 1 cm, or also if SFH or AC drop \> 50 percentiles comparing two subsequent evaluations. Patients randomized to SFH + POC-US will have a formal US if either technique suspects abnormal fetal growth. Formal US requested due to an abnormal screening test will be distinguished from scans ordered due to other indications, such as hypertensive disorders of pregnancy, or cholestasis of pregnancy diagnosed after enrollment. Hadlock' s references will be used to estimate fetal weight, and therefore to define FGR (i.e estimated fetal weight or AC \< 10th percentile) as well as macrosomia (i.e estimated fetal weight or AC \> 90th percentile). Prenatal evaluation of fetal growth will be compared to the birthweight percentile according to the INeS neonatal charts (Bertino 2010) to identify SGA, LGA and AGA (appropriate for gestational age) infants. After the initial evaluation low risk pregnancies are scheduled for antenatal appointments with a midwife at 40, 41 and 41+ weeks' gestation. All patients will have a POC-US by a midwife at 41, and 41+ weeks' gestation to screen for amniotic fluid abnormalities associated with protracted pregnancy, independently of the randomization arm. A midwife will perform SFH or SFH + POCT-US (according to randomization) at enrolment (35-38 weeks' gestation) and at 40 weeks. As sonographic assessment of fetal growth should not be performed more frequently than every 2 weeks due to the error associated with measurements; POC-US will only evaluate amniotic fluid volume at 41 and 41+3 weeks' gestation (unless the patient has missed a previous appointment), even among women randomized to SFH + POC-US. The purpose of the study is to evaluate the most accurate approach to identify prenatally those pregnancies that will result in SGA or LGA infants. Prenatal evaluation consists in a universal screening test for fetal growth abnormalities (either SFH or SFH + POC US) followed by a confirmatory test (formal obstetric US) performed only when the initial screening test is positive. Fetal growth or amniotic fluid abnormalities are diagnosed in utero if confirmed by a formal obstetric ultrasound, and not when only suspected by a screening test; in fact, the study seeks to evaluate what is the most accurate combination of screening and confirmatory tests, and not the effectiveness of the screening test alone.

Investigators are using a pseudo randomized yoked design and will include two groups: choice of intervention strategy or no-choice. If the individual is randomized to no choice, then the next person would get a choice and the no choice person would be assigned to the group yoked (matched) to the person with a choice. Participants assigned to the choice group will choose one of three intervention strategies provided; either Group A (receiving both nutrition and exercise simultaneously), B (starting with nutrition and receiving exercise sequentially followed by nutrition starting at 25 weeks) or C (starting with nutrition first and then introducing exercise sequentially at 25 weeks). All groups will follow the full NELIP until delivery. Participants in the no-choice group will be yoked (matched) to a participant in the choice group and receive the strategy that their yoked counterparts chose. Nutrition component of NELIP: This component is a modified gestational diabetic meal plan that has four general goals tailored to the participant: (1) to achieve approximately 2000 kcal of energy per day. The determination of the amount of kcal consumed per day will consider the participant's intake from the dietary assessment. There also must not be a restriction of calories that exceeds 30% of their total energy intake; (2) participants will consume approximately 200-250g/day of carbohydrates, accounting for approximately 40-55% of total energy intake. Carbohydrate intake will be distributed throughout three meals and four snacks daily. The nutritionist will educate participants about the importance of complex and low-glycemic index carbohydrates through the one-on-one session; (3) fat and protein intake will be approximately 30% and 20-30% of total energy intake, respectively; (4) achieve appropriate micronutrient and fluid intake for pregnancy. This will be monitored by a weekly 24 hour food intake record. Exercise component of NELIP: This is a walking program that comprises of 1 weekly supervised session on a treadmill or outside and participants will be recommended to walk 2 to 3 additional times per week. The walking program will start at 25 minutes per session, 3 to 4 times weekly, and increase by 2 minutes per week until 40 minutes and then maintained until delivery. This will be monitored by a wrist monitoring device. The primary outcome is adherence measured weekly using a published adherence protocol using a point system. Secondary outcomes are participant satisfaction to the program and health outcomes: weekly weight gain, calculated EGWG, and pregnancy outcomes (birth weight length, infant anthropometrics, APGAR scores and delivery complications). At 2, 6 and 12 months of age the maternal-infant dyad will return to the lab and infant morphometric measurements recorded from birth will be repeated.

The current prospective cohort study aims to investigate the dynamic serum kisspeptin levels in the patients with polycystic ovary syndrome (PCOS) at different trimesters of pregnancy, to analyze the associations between serum kisspeptin, insulin, glucose and testosterone, and to explore the predictive value of kisspeptin for GDM and other complications in PCOS patients.

The goal of this observational study is to learn about the therapeutic effects of the conservative treatment approach on pepole with retained products of conception (RPOC) and Enhanced myometrial vascularity (EMV). The main question it aims to answer is: Is it possible to achieve the natural resolution of RPOC by combining it with EMV through conservative treatment？ Participants will receive conservative treatment (such as mifepristone, GnRH-a, or expectant management) following the initial diagnosis of RPOC and EMV, and the therapeutic efficacy of the conservative approach will be assessed after the completion of two menstrual cycles.

The objective of this study is to evaluate the benefit of Karl Storz curved (11508AAK) and straight (11506AAK) fetoscopes for in-utero surgery. The investigators will assess the surgical outcomes, short and long-term morbidity, complications, and gestational age of participants who undergo intrauterine procedures with these devices. The scopes will be used to assist in intrauterine procedures across a variety of fetal conditions, such as TTTS (twin-twin transfusion syndrome), TAPS (twin anemia polycythemia sequence), sFGR (selective fetal growth restriction) or TRAP sequence (twin reversed arterial perfusion). Fetoscopic laser photocoagulation (FLP) can also be used during in-utero surgery to correct abnormal vessels in cases like chorioangioma or vasa previa. Other complex congenital anomalies may require fetal intervention or diagnostic fetoscopy using Storz scopes. Improvements in the technique, experience and equipment have been associated with better maternal, fetal, and neonatal outcomes in fetal surgery. Smaller fetoscopes are associated with lower rates of premature delivery following FLP. New fetoscopes (11508AAK and 11506AAK) have the potential to improve visualization and the photocoagulation angle. Compared to alternative scopes, these Storz scopes provide a wider angle of view and are longer, enabling better reach to distant areas at the edge of the placenta, especially in cases of higher BMI, higher gestational age, and significant polyhydramnios. This study is an un-blinded, non-randomized, single arm, feasibility study on a convenience cohort to demonstrate the role of a curved fetoscope device (11508AAK) or straight fetoscope device (11506AAK) among in-utero surgeries. Patients will be enrolled in a consecutive manner and all qualifying, patients who agreed to the use of the curved or straight fetoscopes will be enrolled in the study. Outcome data will be reported as a descriptive statistical analysis. The curved fetoscope (11508AAK) device will be used in monochorionic pregnancies with an anterior placenta requiring in-utero surgery, while the straight fetoscope (11506AAK) will be used in monochorionic pregnancies with a posterior placenta. This device is classified as a significant risk device because it is of substantial importance in diagnosing, curing, mitigating, or treating disease, or otherwise preventing impairment of human health and presents a potential for serious risk to the health, safety, or welfare of a subject.

At present, there is no unified standard for the treatment of missed abortion in clinical practice. This study intends to collect clinical data of this type of disease to compare the efficacy of different treatments, and on this basis, presuppose the synergistic effect of different doses of estrogen in the process of drug induction, conduct statistical analysis of the efficacy, evaluate whether the treatment plan can achieve the therapeutic effect while reducing the occurrence of complications, and provide an effective basis for the subsequent clinical treatment of missed abortion. This study is divided into two parts. The first part is a retrospective analysis to explore the differences between missed abortion surgery and drug treatment, clinical efficacy and reproductive outcomes; the second part is a prospective study to explore the effects of different doses of estrogen combined with surgery or drug abortion on the efficacy of missed abortion in early pregnancy, and explore the best clinical treatment method for missed abortion.

Pregnancy complications are increasing in the United States, and this is worse for Black patients, who are 3-4 times more likely to die from pregnancy than White patients. Pregnancy complications and deaths cause large physical, social, and financial burdens for patients and their families. Black patients who experience higher levels of institutional racism and discrimination from healthcare providers and institutions are more likely to have pregnancy complications, such as delivering a baby with low birthweight. Low birthweight (less than 5 pounds 9 ounces) is related to many short-term and long-term health problems for both baby and mother. The study, Accountability for Care through Undoing Racism and Equity for Moms (ACURE4Moms), aims to decrease pregnancy complications for all patients, but especially for Black patients, by decreasing institutional racism and bias in healthcare and improving community-based social support during pregnancy. The primary outcome will be to decrease low birthweight deliveries among Black women. The investigators will get information about low birthweight and other pregnancy outcomes from prenatal practice electronic healthcare records. A secondary outcome will be to decrease experiences with discrimination during prenatal care among Black patients; this information will be collected from an internet survey that will be completed at 4 time points between a patient's first prenatal visit and 3 months after delivery. To meet the study aims, the investigators will test 2 types of interventions. The first type (the "Data Accountability and Transparency interventions") will be focused on healthcare providers and their clinics. The study will improve accountability by setting up electronic Maternal Warning Systems to notify the clinics whenever a patient has a risk factor for low birthweight that needs to be treated or misses a scheduled appointment. Nurse navigators and provider champions from each clinic will make sure the clinic acts on the warning. Secondly, the study will improve transparency by showing the clinics their pregnancy-related complication data for different racial groups every 3 months through a "Disparities Dashboard." This Dashboard will show the providers any differences in pregnancy complications for people of different races in their clinic and encourage them to come up with ways to improve the quality of their care to decrease those differences. The study will hire "Practice Facilitators" to help the clinics improve their workflows and communication with patients. Finally, all the staff at the clinics will undergo interactive racial equity training to help them recognize any implicit biases they have and understand how racism affects pregnancy care for patients of color. The second type of interventions will be focused on improving community-level support for high-risk pregnant patients. The study will do this by matching community-based doulas who are trained to provide culturally-relevant care with high-risk patients after their first prenatal appointment. The doulas will then provide support to these patients during pregnancy and up to 1 year after birth by setting up peer support groups for clients with similar due dates, attending 2 prenatal visits with them, supporting them for up to 24 hours during labor, and performing a postpartum home visit (the "Community-Based Doula Support interventions"). To test how these each of these interventions improves low birthweight alone and when combined together, the study has enrolled 39 prenatal practices across North Carolina, into 1 of 4 randomized arms: 1) No interventions; 2) Data Accountability and Transparency interventions; 3) Community-Based Doula Support interventions; or 4) Both the Data Accountability and Transparency and Community-Based Doula Support interventions. The investigators predict that up to 60,000 patients will start prenatal care at one of the 39 practices during the study. For the patient surveys, the study plans to enroll patients who self-identify as Black or African American from each of the 39 practices, for a total of at least 2,400 survey participants. The investigators will also interview up to 250 practice staff, doulas, patients, and Practice Facilitators to understand how well the study interventions fit their needs. The study is led by a Stakeholder Advisory Board, which includes patients of color who have had a pregnancy complication, community doulas, practice representatives, health insurance payers, a patient advocacy group, healthcare organizations, and the North Carolina Department of Public Health. The majority of members will be people of color. The Board will meet every 3 months throughout the study to advise us about patient-centered outcomes, assist with dissemination of results, and advocate for related policy change.

When the transition from intrauterine to extrauterine life necessitates Neonatal Resuscitation, specialized monitoring of vital signs is required. Sudden Unexpected Postnatal Collapse (SUPC) is an apnea or cardiorespiratory failure occurring in otherwise healthy near-term or term neonates, usually in the first 48 hours of age, during the initial Kangaroo Mother Care (KMC) in the obstetrical center. SUPC carries a high morbidity and mortality rate. Approximately 10 million babies do not breathe immediately after birth, and 60% require basic resuscitation interventions. Sudden Unexpected Postnatal Collapse has been estimated to occur in 2.6-133 cases per 100.000 newborns and over 50% of the cases occur following accidental suffocation, which frequently goes unrecognised by parents in the obstetrical center during unsupervised KMC. Current guidelines recommend monitoring of heart rate (HR), oxygen saturation (SpO2), and skin temperature (Tskin) during neonatal resuscitation. This is usually achieved by using wired electrodes and sensors that require expensive and large base units attached to a power supply. SUPC is a rare but largely preventable cause of neonatal mortality that deserves particular attention. Better resuscitation and prevention of SUPC might be achieved by continuous non-intrusive monitoring of vital signs immediately after delivery and while in the obstetrical center. This research will address a very important gap in care; the need for safe and accurate advanced, non-invasive, and non-intrusive wireless technologies for monitoring of vital signs immediately after birth and during the immediate postnatal care, potentially preventing cases of SUPC while in the obstetrical center. Reliable and low-cost wireless monitoring that could be used immediately after delivery would promote widespread adoption of neonatal resuscitation recommendations in low and middle income countries, improve detection of vital signs quickly after delivery and during early unsupervised KMC, and optimize neonatal care in the obstetrical centers or during hospital stay, to prevent cases of SUPC and its associated high mortality.

The Femom device is a non-invasive fetal ECG (NIFECG) device which has been developed for self application and remote monitoring. Women from three different cohort groups (controls, FGR and insulin dependent diabetes) will be approached and asked to monitor their baby at home once a day. Women in the control group will be asked to do this once a day for one week, the FGR pregnancies until delivery and the insulin dependent diabetics just from 36 weeks until delivery. The data will be collected and analysed retrospectively to assess compliance of the participants with the study protocol, signal quality and establish reference standards in relation to gestation within the control group. Heart rate variability measures in the FGR and diabetes arm will be compared to the reference standards in the control group. Outcomes of the pregnancy. Feedback regarding the usability of the device will also be collected using a feedback questionnaire to assess the feasibility of home antenatal monitoring.

Fetal renal failure (FRF) is a severe and life-threatening condition caused by congenital abnormalities or inherited kidney diseases. In the womb, when the kidneys fail to function properly, this leads to a condition called anhydramnios-a complete lack of amniotic fluid. Amniotic fluid is essential for the fetus's lung development, particularly during the canalicular phase of pulmonary development, which occurs between 16 and 28 weeks of gestation. Without sufficient amniotic fluid, the lungs cannot develop properly, resulting in a condition known as pulmonary hypoplasia. Severe hypoplasia has previously been described as almost always fatal, typically leading to neonatal death shortly after birth. In recent years, promising advances in fetal therapies have opened new doors for treating conditions that were once considered untreatable. One such intervention involves serial amnioinfusion, a procedure where sterile saline or another isotonic fluid is injected into the amniotic sac to restore fluid levels. Early studies, including the RAFT trial (Renal Anhydramnios Fetal Therapy), have demonstrated that this approach may improve survival rates by promoting lung development in fetuses with FRF. Building upon these findings, this study seeks to further evaluate the safety and effectiveness of serial amnioinfusion in improving neonatal outcomes for families facing this diagnosis. This study will enroll approximately 60 pregnant individuals carrying singleton pregnancies complicated by FRF and anhydramnios. Participants will be divided into two groups: an intervention group, which will receive serial amnioinfusion procedures as deemed appropriate by the study doctor, and a control group, which will not undergo interventions and will receive comfort care for their pregnancies. The primary goals of the study are to evaluate maternal safety, assess fetal survival to dialysis, and determine survival to kidney transplant eligibility. The amnioinfusion procedures will be performed at the Fetal Care Center by a team of experts in fetal procedures. To ensure patient safety, the study includes a rigorous monitoring plan to track any potential adverse events in real time. Data from imaging studies (e.g., ultrasound, echocardiogram, MRI) and laboratory biomarkers will be collected to evaluate fetal and maternal responses to the treatment. While the study focuses on improving outcomes for individual patients, it also has broader implications for science and society. By systematically analyzing the benefits and risks of serial amnioinfusion, this research could help refine treatment protocols and set the stage for new standards of care for FRF. For the families involved, participation in this study offers the possibility of improved survival for their children, with potential eligibility for life-saving kidney transplants in the future. This study represents a critical step toward addressing a condition that has long been considered untreatable. Through collaboration, innovation, and rigorous research, the team aims to provide hope for families affected by FRF.
