Impact of endocrine disorders on stillbirth: a prospective cohort study.

OBJECTIVE: Among risk factors for SB, maternal endocrine diseases (ED), such as thyroids dysfunction and gestational diabetes mellitus (GDM), are the most frequent. This study aimed to investigate the rate of ED in a population of SB cases collected prospectively, and the relationship between these and causes of death. METHODS: This is an area-based, prospective cohort study conducted in Emilia-Romagna, Italy between January 2014 and December 2020. Data included all cases of SB (>22 weeks). RESULTS: From 2014 to 2020, 766 SB occurred out of a total of 232.506 births (SB rate:0.3/1000). The ED were present in 197/766 cases of SB (25.7%), respectively, 104 thyroid disease (52.8%), 74 GDM (37.5%), and 19 cases of concomitant GDM and thyroid disease (9.6%). Women who had SB associated with ED presented significantly higher mean maternal age (p < 0.001), BMI (p < 0.001), obesity (p < 0.001) and lower smoking habit (p = 0.02) respect with control group. Neonatal and placental weight of stillborn women with ED was significantly higher (p < 0.001) in respect to stillborn of the control group. Women with ED as associated condition (ReCODE classification), present significantly higher cases of SB caused by placenta pathologies (p = 0.009) namely abruptio placentae (p = 0.001) respect than control group. CONCLUSIONS: ED was more frequent in older and obese women experiencing SB. The main cause of death was abruptio placentae. This information can be helpful when counseling mothers with ED and planning antenatal management to prevent SB.

Intrapartum stillbirth for sepsis complicating Arabin cervical pessary placement in a twin pregnancy.

There is little evidence regarding the best treatment in case of dilated cervix and exposed membranes in twins. Current options for its management include vaginal progesterone, cervical cerclage and cervical pessary, but none of them had shown effectiveness compared to expectant management. We presented a case of twin pregnancy at 22 6/7 weeks' gestation admitted to the hospital because of cervical insufficiency with bulging of membranes. An Arabin pessary was positioned after a failed attempt of cervical cerclage and no antibiotic was given in absence of signs of infection. Cesarean delivery was performed at 24 weeks' gestation because of spontaneous preterm labor and spontaneous rupture of membranes with the first baby in a transverse lie position. At the uterus section, the first baby was stillborn, with Arabin pessary strictly adherent to his ecchymotic head, while the second baby was born alive. After diagnostic histopathological and microbiological investigations, we hypothesized that the first twin died for funisitis/sepsis and mechanical insult due to the strict adhesion of the pessary to the fetal head. We concluded that in case of bulging membranes and dilated cervix, antibiotic treatment should be evaluated, also in absence of signs/symptoms of infection or suspicion of rupture of the membranes, and pessary insertion should be avoided, namely at second trimester, because of the risk of its dislocation inside the uterus when contractions start and potential hurt to extremely preterm fetus.

Potentially preventable antepartum stillbirths in a high-resource setting: a prospective audit-based study.

OBJECTIVES: The primary objective was the identification of sub-standard care in antepartum stillbirths in Emilia-Romagna Region (Italy), hence the number of potentially preventable cases. Secondly, we seek to evaluate any association between inadequate care and either risk factors for stillbirth or causes of death. STUDY DESIGN: This study was based on prospectively-collected data in an institutional stillbirth audit project, involving all 29 hospital with a maternity unit in Emilia-Romagna Region. For each stillbirth occurred in the area from 2014 to the first semester of 2019 the same diagnostic workup was performed and a clinical record with data about mother and stillborn was completed. Every case was discussed in a multidisciplinary local audit to assess both the cause of death and the quality of care. Two aspects of care quality were evaluated: clinical management and women's access to care. Data were then reviewed by the Regional Audit Group. RESULTS: Elements of inadequate care were identified in 56 out of 524 (10.7 %) fetal deaths. Non-Italian women and pregnancies with fetal growth restriction had double the risk of having received inadequate care during pregnancy, compared to Italian women (aOR 2.0, 95 % CI 1.1-3.6) and a normally developing fetus (aOR 2.0, 95 % CI 1.1-4.1), respectively. Women whose stillbirth was caused by maternal disorders were at higher risk for inadequate care compared to women who had stillbirth explained by other cause (aOR 5.89, 95 %CI 2.2-15.4). Sub-optimal clinical management and barriers to access to care were observed to equal extents. Inappropriate ultrasound monitoring was the most frequent suboptimal care element. CONCLUSIONS: About one out of ten stillbirths was potentially preventable. Interventions to reduce stillbirth occurrence in our high-resource setting should focus on appropriate diagnosis and management of maternal disorders and fetal growth restriction, as well as improving access to antenatal care.

The Burden of Placental Histopathology in Stillbirths Associated With Maternal Obesity.

OBJECTIVES: Obesity is an increasing health problem that has become a common medical disorder among women of childbearing age, representing worldwide a risk factor for stillbirth. The aim of the study is to evaluate the association between placental histopathologic findings and obesity in stillbirth. METHODS: Placentas were analyzed according to the Amsterdam consensus statement. Histologic findings in stillbirth from obese and lean mothers were analyzed and compared with those observed in liveborn controls. RESULTS: Stillbirth in obese mothers displayed placental pathology in all gestational ages, mostly at term of pregnancy. The most observed placental lesions were those consistent with maternal vascular malperfusion of the placental bed. Decidual arteriopathy and placental infarcts appeared specifically associated with maternal obesity. Moreover, obese women with stillbirth showed the highest cumulative number of placental lesions. CONCLUSIONS: Considering the significant association between stillbirth, maternal obesity, and placental histopathologic findings, health care providers should be aware about the importance of placental examination in obese women, especially in stillborn cases. The high prevalence of lesions consistent with vascular malperfusion of the placental bed suggests that stillbirth prevention strategies in obese women should rely on the development of tools to study and improve decidual artery functioning early in pregnancy.

Fetal Movement Counting and Perinatal Mortality: A Systematic Review and Meta-analysis.

OBJECTIVE: To assess the association of fetal movement counting with perinatal mortality. DATA SOURCES: Electronic databases (ie, MEDLINE, ClinicalTrials.gov, ScienceDirect, the Cochrane Library at the CENTRAL Register of Controlled Trials) were searched from inception until May 2019. Search terms used were: "fetal movement," "fetal movement counting," "fetal kick counting," "stillbirth," "fetal demise," "fetal mortality," and "perinatal death." METHODS OF STUDY SELECTION: We included all randomized controlled trials comparing perinatal mortality in those women randomized to receive instructions for fetal movement counting compared with a control group of women without such instruction. TABULATION, INTEGRATION AND RESULTS: The primary outcome was perinatal mortality. Five of 1,290 identified articles were included, with 468,601 fetuses. Definitions of decreased fetal movement varied. In four of five studies, women in the intervention group were asked to contact their health care providers if they perceived decreased fetal movement; the fifth study did not provide details. Reported reduction in fetal movement usually resulted in electronic fetal monitoring and ultrasound assessment of fetal well-being. There was no difference in the incidence of perinatal outcome between groups. The incidence of perinatal death was 0.54% (1,252/229,943) in the fetal movement counting group and 0.59% (944/159,755) in the control group (relative risk [RR] 0.92, 95% CI 0.85-1.00). There were no statistical differences for other perinatal outcomes as stillbirths, neonatal deaths, birth weight less than 10th percentile, reported decreased fetal movement, 5-minute Apgar score less than 7, neonatal intensive care unit admission or perinatal morbidity. There were weak but significant increases in preterm delivery (7.6% vs 7.1%; RR 1.07, 95% CI 1.05-1.10), induction of labor (36.6% vs 31.6%; RR 1.15, 95% CI 1.09-1.22), and cesarean delivery (28.2% vs 25.3%; RR 1.11, 95% CI 1.10-1.12). CONCLUSION: Instructing pregnant women on fetal movement counting compared with no instruction is not associated with a clear improvement in pregnancy outcomes. There are weak associations with some secondary outcomes such as preterm delivery, induction of labor, and cesarean delivery. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42019123264.

A regional audit system for stillbirth: a way to better understand the phenomenon.

BACKGROUND: Implementation of high-quality national audits for perinatal mortality are needed to improve the registration of all perinatal deaths and the identification of the causes of death. This study aims to evaluate the implementation of a Regional Audit System for Stillbirth in Emilia-Romagna Region, Italy. METHODS: For each stillbirth (≥ 22 weeks of gestation, ≥ 500 g) occurred between January 1, 2014 to December 1, 2016 (n = 332), the same diagnostic workup was performed and a clinical record with data about mother and stillborn was completed. Every case was discussed in a multidisciplinary local audit to assess both the cause of death (ReCoDe classification) and the quality of care. Data were reviewed by the Regional Audit Group. Stillbirth rates, causes of death and the quality of care were established for each case. RESULTS: Total stillbirth rate was 3.09 per 1000 births (332/107,528). Late stillbirth rate was 2.3 per 1000 (251/107,087). Sixteen stillbirths were not registered by the Regional Birth Register. The most prevalent cause of death was placental disorder (33.3%), followed by fetal (17.6%), cord (14.2%) and maternal disorders (7.6%). Unexplained cases were 14%. Compared to local audits, the regional group attributed different causes of death in 17% of cases. At multivariate analysis, infections were associated with early stillbirths (OR 3.38, CI95% 1.62-7.03) and intrapartum cases (OR 6.64, CI95% 2.61-17.02). Placental disorders were related to growth restriction (OR 1.89, CI95% 1.06-3.36) and were more frequent before term (OR 1.86, CI95% 1.11-3.15). Stillbirths judged possibly/probably preventable with a different management (10.9%) occurred more frequently in non-Italian women and were mainly related to maternal disorders (OR 6.64, CI95% 2.61-17.02). CONCLUSIONS: Regional Audit System for Stillbirth improves the registration of stillbirth and allows to define the causes of death. Moreover, sub-optimal care was recognized, allowing to identify populations which could benefit from preventive measures.

Intraoperative fetal heart monitoring for non-obstetric surgery: A systematic review.

Limited data are available on fetal monitoring during non-obstetric surgery in pregnancy. We performed a systematic review to evaluate the incidence of emergent cesarean delivery performed for non-reassuring fetal heart rate patterns during non-obstetric surgery. Electronic databases were searched from their inception until October 2018 without limit for language. We included studies evaluating at least five cases of intraoperative fetal heart rate monitoring -either with ultrasound or cardiotocography- during non-obstetric surgery in pregnant women at ≥22 weeks of gestation. The primary outcome was the incidence of intraoperative cesarean delivery performed for non-reassuring fetal heart rate monitoring. Non-reassuring fetal heart rate monitoring was defined by attendant personnel, meeting NICHD criteria for category II or III patterns. Data extracted regarded type of study, demographic characteristics, maternal and perinatal outcomes. Statistical analysis was performed for continuous outcomes by calculating mean and standard deviations for appropriate variables. Of 120 studies identified, 4 with 41 cases of intraoperative monitoring met criteria for inclusion and were analyzed. Most (66%) surgeries were indicated for neurological or abdominal maternal issues and were performed under general anesthesia (88%) at a mean gestational age of 28 weeks. Minimal or absent fetal heart variability was noted in most cases and a 10-25 beats per minutes decrease in fetal heart rate baseline was observed in cases with general anesthesia. No intraoperative cesarean deliveries were needed. The incidence of non-reassuring fetal heart rate monitoring was 4.9% (2/41) and were limited to fetal tachycardia during maternal fever. Two (4.9%) cases of non-reassuring fetal heart rate monitoring were noted within the immediate 48 h after surgery, necessitating cesarean delivery. A single case of intrauterine fetal demise occurred four days postoperatively in a woman who had neurosurgery and remained comatose. In conclusion, limited data exist regarding the clinical application of fetal heart rate monitoring at viable gestational ages during non-obstetric surgical procedures. Fetal heart rate monitoring during non-obstetric surgery at ≥22 weeks was not associated with need for intraoperative cesarean delivery, but two (4.9%) cesarean deliveries were performed for non-reassuring fetal heart rate monitoring within 48 h after surgery.
