RESUMO
BACKGROUND: The aim of this extended review of multicenter case series is to describe the prenatal ultrasound features and pathogenetic mechanisms underlying placental and umbilical cord anomalies and their relationship with adverse perinatal outcome. From an educational point of view, the case series has been divided in three parts; Part 1 is dedicated to placental abnormalities. METHODS: Multicenter case series of women undergoing routine and extended prenatal ultrasound and perinatal obstetric care. RESULTS: Prenatal ultrasound findings, perinatal care, and pathology documentation in cases of placental pathology are presented. CONCLUSIONS: Our case series review and that of the medical literature confirms the ethiopathogenetic role and involvement of placenta abnormalities in a wide variety of obstetrics diseases that may jeopardize the fetal well-being. Some of these specific pathologies are strongly associated with a high risk of poor perinatal outcome.
RESUMO
BACKGROUND: Perinatal mortality is a global health problem, especially in Ethiopia, which has the highest perinatal mortality rate. Studies about perinatal mortality were conducted in Ethiopia, but which factors specifically contribute to the change in perinatal mortality across time is unknown. OBJECTIVES: To assess the trend and multivariate decomposition of perinatal mortality in Ethiopia using EDHS 2005-2016. METHODS: A community-based, cross-sectional study design was used. EDHS 2005-2016 data was used, and weighting has been applied to adjust the difference in the probability of selection. Logit-based multivariate decomposition analysis was used using STATA version 14.1. The best model was selected using the lowest AIC value, and variables were selected with a p-value less than 0.05 at 95% CI. RESULT: The trend of perinatal mortality in Ethiopia decreased from 37 per 1000 births in 2005 to 33 per 1000 births in 2016. About 83.3% of the decrease in perinatal mortality in the survey was attributed to the difference in the endowment (composition) of the women. Among the differences in the endowment, the difference in the composition of ANC visits, taking the TT vaccine, urban residence, occupation, secondary education, and birth attendant significantly decreased perinatal mortality in the last 10 years. Among the differences in coefficients, skilled birth attendants significantly decreased perinatal mortality. CONCLUSION AND RECOMMENDATION: The perinatal mortality rate in Ethiopia has declined over time. Variables like ANC visits, taking the TT vaccine, urban residence, occupation, secondary education, and skilled birth attendants reduce perinatal mortality. To reduce perinatal mortality more, scaling up maternal and newborn health services has a critical role.

Placental abruption, the premature placental separation, confers increased perinatal mortality risk with preterm delivery as an important pathway through which the risk appears mediated. While pregnancies complicated by abruption are often delivered through an obstetrical intervention, many deliver spontaneously. We examined the contributions of clinician-initiated (PTDIND) and spontaneous (PTDSPT) preterm delivery at <37 weeks as competing causal mediators of the abruption-perinatal mortality association. Using the Consortium for Safe Labor (2002-2008) data (n = 203,990; 1.6% with abruption), we applied a potential outcomes-based mediation analysis to decompose the total effect into direct and mediator-specific indirect effects through PTDIND and PTDSPT. Each mediated effect describes the reduction in the counterfactual mortality risk if that preterm delivery subtype was shifted from its distribution under abruption to without abruption. The total effect risk ratio (RR) of abruption on perinatal mortality was 5.4 (95% confidence interval [CI] 4.6, 6.3). The indirect effect RRs for PTDIND and PTDSPT were 1.5 (95% CI: 1.4, 1.6) and 1.5 (95% CI: 1.5, 1.6), respectively; these corresponded to mediated proportions of 25% each. These findings underscore that spontaneous and clinician-initiated preterm deliveries each play essential roles in shaping perinatal mortality risks associated with placental abruption.
RESUMO
BACKGROUND: Globally, perinatal mortality rates have decreased considerably in the last 30 years. However, in sub-Saharan African countries perinatal mortality remains a public health burden. Therefore, this study aimed to determine the Perinatal Mortality Rate and the factors associated with perinatal mortality in Beni City, Northeastern Democratic Republic of Congo. METHODS: A hospital-based retrospective cross-sectional study was conducted among 1394 deliveries that were documented in Beni General Referral Hospital from 2 January to May 31, 2022. The study was done in the conflict-ridden Beni city of the North Kivu Province. Analysis was done using Open Epi and SPSS version 22. Binary and Multivariate logistic regression analyses were performed. Odds ratio with 95% confidence interval was used to measure strength of association. RESULTS: Findings indicate that 60.7% of 1394 participants were below the age of 21 years, and 95.1% (1325) Beni residents. The Perinatal Mortality Rate was 42.3 per 1000 live births. Majority (51) of the postpartum women who experienced perinatal mortality didn`t have a history of perinatal mortality as compared to their counterparts. Multivariable analysis revealed that birth weight (AoR = 0.082, 95% CI 0.014-0.449, p < 0.05) and Apgar score in the 10th minute (AoR = 0.082, 95% CI 0.000- 0.043, p < 0.05) were significantly associated with Perinatal mortality. CONCLUSION: The high perinatal mortality rate in Beni General Referral Hospital, approximately four in every 100 births remains a disturbing public health concern of which is attributable to low birth weight and Apgar score. This study may help policy-makers and healthcare providers to design preventive interventions.
RESUMO
Background: Antenatal corticosteroids (ACS) are given to pregnant women at risk of preterm delivery to hasten the maturation of the lungs, lowering the risk of newborn respiratory distress syndrome (RDS) and perinatal mortality. Objective: The aim of this study was to determine whether exposure to ACS was associated with lower rates of perinatal mortality and RDS in preterm infants delivered by women with preterm labour. Methods: This is a secondary analysis of data from four hospitals in Mwanza, Tanzania. All singletons and twins born to women who were in preterm labour between July 2019 and February 2020 and delivered in-hospital between 24 and 34 weeks of gestation were included. Data were recorded from participants' medical records and analysed using STATA Version 14. Results: Over an eight-month period, 588 preterm infants were delivered to 527 women. One hundred and ninety (36.1%) women were given ACS. Infants who were exposed to ACS in utero had a lower rate of perinatal mortality (6.8% vs 19.1%) and RDS (12.3% vs 25.9%) compared to those not exposed to ACS. In adjusted multivariable models, ACS exposure was related to a lower risk of perinatal mortality, aRR 0.23 (95% CI 0.13 - 0.39), and RDS, aRR 0.45 (95% CI 0.30 - 0.68). Conclusion: ACS significantly reduced the risk of perinatal mortality and RDS among preterm infants exposed to ACS in utero and delivered by women in preterm labour. The use of ACS should be encouraged in low-resource settings where preterm birth is prevalent to improve perinatal outcomes.

OBJECTIVE: To evaluate the frequency and interrelationships among neonatal near miss (NNM) criteria and the anticipated workload for audits in high-income countries. DESIGN: Observational retrospective descriptive study. SETTING: Tertiary maternal and neonatal units at Mater Mothers' Hospital, Brisbane, Queensland, Australia. PARTICIPANTS: Cases of stillbirths (n = 483), neonatal deaths (n = 203), and live births (n = 66,353) from January 2016 to July 2022 (N = 67,039). METHODS: We identified eight prespecified NNM criteria nominated by perinatal experts. Primary outcomes were NNM frequency, their interrelationships, and related workload. We used descriptive statistics and analysis of variance and considered p < .05 significant. RESULTS: We found 2,243 unique NNM cases (33.7/1,000 live births). The NNM ratio per 1,000 live births according to each of the eight criteria were: unplanned resuscitation at birth (25.09/1,000 live births), birth asphyxia needing surveillance for hypoxic ischemic encephalopathy (8.46/1,000 live births), metabolic acidosis at birth (8.04/1,000 live births), advanced resuscitation at birth (3.68/1,000 live births), seizures and/or stroke (0.96/1,000 live births), severe intraventricular hemorrhage and/or cerebellar hemorrhage (0.95/1,000 live births), moderate to severe hypoxic ischemic encephalopathy (0.9/1,000 live births), and severe birth trauma (0.44/1,000 live births). Almost one third of NNM cases met more than one criterion. Anticipated workload for monthly NNM audits varied from 0.04 to 2.8 cases per 1,000 live births. CONCLUSION: Different sets of NNM criteria considerably alter the frequency of NNMs and the anticipated workload for NNM audits. Their interrelationships are likely attributable to the fact that some of the criteria are risk factors for or are part of the causal pathway for other NNM criteria. These findings can assist with the determination of a pragmatic NNM definition considering the feasibility of NNM audits in high-income countries.
RESUMO
OBJECTIVE: To identify factors associated with the receipt, completion, and goals of palliative care birth plans during the prenatal period. DESIGN: Retrospective observational study of medical record data. SETTING: Midwestern U.S. quaternary pediatric hospital. PARTICIPANTS: Maternal-fetal dyads who received maternal-fetal medicine and palliative care from July 2016 through June 2021 (N = 128). METHODS: Using demographic and clinical predictors, we performed descriptive statistics, group comparisons (chi-square or Fisher exact test and Wilcoxon rank sum test or Student t test), and logistic regression for three outcomes: birth plan offered, birth plan completed, and goals of care (comfort-focused vs. other). RESULTS: Of 128 dyads, 60% (n = 77) received birth plans, 30% (n = 23) completed them, and 31% (n = 40) expressed comfort-focused goals. Participants with comfort-focused goals compared to other goals were more likely to receive birth plans, odds ratio (OR) = 7.20, 95% confidence interval (CI) [1.73, 29.9], p = .01. Participants of non-Black minority races had lower odds of being offered birth plans when compared to White participants, OR = 0.11, 95% CI [0.02, 0.68], p = .02. Odds of being offered (OR = 11.54, 95% CI [2.12, 62.81], p = .005) and completing (OR = 4.37, 95% CI [1.71, 11.17], p < .001) the birth plan increased with each prenatal palliative care visit. Compared to those without, those with neurological (OR = 9.32, 95% CI [2.60, 33.38], p < .001) and genetic (OR = 4.21, 95% CI [1.04, 17.06], p = .04) diagnoses had increased odds of comfort-focused goals. CONCLUSION: Quality improvement efforts should address variation in the frequency at which birth plans are offered. Increasing palliative care follow-up may improve completion of the birth plan.
RESUMO
Aim: Perinatal mortality can be used as a reference to assess health status in a country. In Indonesia, none of previous studies specifically discuss the incidence of prenatal mortality by region. The objective of this study was to analyze perinatal mortality difference by region of Indonesia. Study design: This study used a cross-sectional approach. Method: The sample in this study was 13,310 women of childbearing age obtained from the Indonesian Demographic Health Survey (IDHS) 2017. The perinatal mortality rate was calculated using data on stillbirths with a gestational duration of seven months or more and early neonatal deaths. Perinatal mortality was analyzed by region using a binary logistic regression statistical test to examine the relationship between perinatal mortality and its factors (socio-demographic factors, individual disease control factors, and maternal factors). Results: This study shows that the proportion of perinatal mortality in Indonesia is 1.5 % of total births. The highest proportion of perinatal mortality (2.5 %) was in the Papua region, while the lowest proportion (1.3 %) was in the Java region. The results of this study indicated that women in the Maluku Islands had a 1.82 times higher chance of perinatal mortality compared to the Java-Bali region. The causative variable associated with perinatal mortality in the Java-Bali and Papua regions was employment status. The causative variables associated with perinatal mortality in Kalimantan were the quality of antenatal care and delivery assistance. The causative variable associated with perinatal mortality in Nusa Tenggara and Papua was the location of delivery. The causative variable associated with perinatal mortality in Kalimantan, Maluku, and Papua was the mother's age. The causative variable associated with perinatal mortality in the Java-Bali region was parity. The causative variable associated with perinatal mortality in Sumatra was the type of delivery. Conclusion: This study show that there were disparities in the incidence of perinatal mortality between regions in Indonesia. The government needs to re-adjust the existing strategies to improve health status and focus on community empowerment for women to prevent perinatal mortality.
RESUMO
Background: Few studies have evaluated the effects of the Coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus, on maternal and perinatal health at a populational level. We investigated maternal and perinatal health indicators in Brazil, focusing on the effects of the COVID-19 pandemic, and SARS-CoV-2 vaccination campaign for pregnant women. Methods: Utilizing interrupted time series analysis (January 2013-December 2022), we examined Maternal Mortality Ratio, Perinatal Mortality Rate, Preterm Birth Rate, Cesarean Section Rate, and other five indicators. Interruptions occurred at the pandemic's onset (March 2020) and pregnant women's vaccination (July 2021). Results were expressed as percent changes on time series' level and slope. Findings: The COVID-19 onset led to immediate spikes in Maternal Mortality Ratio (33.37%) and Perinatal Mortality Rate (3.20%) (p < 0.05). From March 2020 to December 2022, Cesarean Section and Preterm Birth Rates exhibited upward trends, growing monthly at 0.13% and 0.23%, respectively (p < 0.05). Post start of SARS-CoV-2 vaccination (July 2021), Maternal Mortality Ratio (-34.10%) and Cesarean Section Rate (-1.87%) promptly declined (p < 0.05). Subsequently, we observed a monthly decrease of Maternal Mortality Ratio (-9.43%) and increase of Cesarean Section Rate (0.25%) (p < 0.05), while Perinatal Mortality Rate and Preterm Birth Rate showed a stationary pattern. Interpretation: The pandemic worsened all analyzed health indicators. Despite improvements in Maternal Mortality Ratio, following the SARS-CoV-2 vaccination campaign for pregnant women, the other indicators continued to sustain altered patterns from the pre-pandemic period. Funding: No funding.
RESUMO
OBJECTIVE: With inconsistencies regarding the possible effect of hyperemesis gravidarum on the course of pregnancy, this research aimed to study the association between hyperemesis gravidarum and pregnancy outcomes, while also addressing the trimester of diagnosis and severity. METHODS: A retrospective cohort study was performed, including all singleton deliveries of mothers from the largest health maintenance organization in the country, in a single tertiary hospital between 1991 and 2021. The incidence of adverse pregnancy outcomes was compared between pregnancies with and without hyperemesis gravidarum diagnosis. Multivariable generalized estimation equation binary models were used to study the association between maternal hyperemesis gravidarum, trimester of diagnosis and hyperemesis gravidarum severity and the studied outcomes. RESULTS: The study population included 232 476 pregnancies, of which 3227 (1.4%) were complicated with hyperemesis gravidarum. Women with hyperemesis gravidarum were more likely to deliver preterm (adj. OR = 1.33, 95% CI: 1.18-1.50), a newborn with low birthweight (adj. OR = 1.52, 95% CI: 1.16-1.98, only if diagnosed in the second trimester), and to have a cesarean delivery (adj. OR = 1.20, 95% CI: 1.09-1.32). They were less likely to deliver small gestational age newborn (adj. OR = 0.82, 95% CI: 0.69-0.99) and their offspring to experience perinatal mortality (adj. OR = 0.54, 95% CI: 0.31-0.93, among mild cases only). A dose-response association was observed between preterm birth and hyperemesis gravidarum (adj. OR = 1.26; 95% CI: 1.11-1.44, for mild cases and adj. OR = 2.04; 95% CI: 1.31-3.19, for severe cases). CONCLUSIONS: Hyperemesis gravidarum is associated with an increased risk for adverse pregnancy outcomes including mainly preterm delivery in a dose-response manner and when diagnosed during the second trimester.
RESUMO
OBJECTIVE: Aim: To predict trends in fertility, neonatal and perinatal mortality, and stillbirth rates to ascertain future perinatal care requirements during the post-war reconstruction in Ukraine. PATIENTS AND METHODS: Materials and Methods: The study uses the data from the Centre for Medical Statistics of the Ministry of Health of Ukraine, covering the years 2012 to 2022. The data analysis was by a univariate linear regression model. The quality of these models was evaluated using the coefficient of determination, R2. RESULTS: Results: In 2022, the birth rate in Ukraine had declined to 2.5 times lower than that of 2011. The period was characterized by a notable increase in the incidence of premature births and in neonates with birth weights under 1000 grams and between 1000 to 2499 grams. While the neonatal mortality rate decreased by 3.7 times, there remains a statistically significant (p<0.05) increase in the mortality rates of premature infants and neonates weighing less than 1000 grams. The stillbirth rate in Ukraine remains constant; however, it exceeds that of the European Union. Predictions indicate a rise in antenatal mortality and a reduction in both intranatal and perinatal mortality. As of 2022, the perinatal mortality rate in Ukraine made up 7.72 per 1000 live births, which is significantly higher than the rate in the European Union. CONCLUSION: Conclusions: The optimization of the network of healthcare facilities and resources should be prioritized, in response to the reliable decline in the birth rate. This necessitates improvements in the medical care for premature and low birth weight infants, and efforts for preventing stillbirths.

OBJECTIVES: Changes in placental features, such as maternal and fetal vascular malperfusion, are associated with SARS-CoV-2 infection. The anatomopathologic study of the placenta is crucial for understanding pregnancy and fetal complications. To that end, this study aimed to describe placental features and analyze the association between placental findings and perinatal outcomes in a cohort of pregnant women with severe COVID-19. METHODS: This nested study within a prospective cohort study consisted of 121 singleton pregnant women with a diagnosis of severe COVID-19. Placental pathologic findings were described, and the associations between severe COVID-19 and clinical parameters and perinatal outcomes were assessed. RESULTS: The prevalence of maternal vascular malperfusion was 52.1%, followed by fetal vascular malperfusion at 21.5%, ascending intrauterine infections at 11.6%, and inflammatory lesions at 11.6%. Other lesions were observed in 39.7% of the placentas examined. Inflammatory lesions were an independent factor (P = .042) in 5-minute Apgar scores below 7. Ascending infection was associated with fetal death (P = .027). CONCLUSIONS: Maternal vascular malperfusion was the most prevalent placental feature in patients with severe COVID-19. Chorangiosis is associated with poor perinatal outcomes.
RESUMO
BACKGROUND: Irregular legal status is a recognized health risk factor in the context of migration. However, undocumented migrants are rarely included in health surveys and register studies. Adverse perinatal outcomes are especially important because they have long-term consequences and societal risk factors are modifiable. In this study, we compare perinatal outcomes in undocumented migrants to foreign-born and Norwegian-born residents, using a population-based register. METHODS: We included women 18-49 years old giving birth to singletons as registered in the Medical Birth Registry of Norway from 1999 to 2020. Women were categorized as 'undocumented migrants' (without an identity number), 'documented migrants' (with an identity number and born abroad), and 'non-migrants' (with an identity number and born in Norway). The main outcome was perinatal mortality, i.e., death of a foetus ≥ gestational week 22, or neonate up to seven days after birth. We used log-binominal regression to estimate the association between legal status and perinatal mortality, adjusting for several maternal pre-gestational and gestational factors. Direct standardization was used to adjust for maternal region of origin. ETHICAL APPROVAL: Regional Ethical Committee (REK South East, case number 68329). RESULTS: We retrieved information on 5856 undocumented migrant women who gave birth during the study period representing 0.5% of the 1 247 537 births in Norway. Undocumented migrants had a relative risk of 6.17 (95% confidence interval 5.29 ̶7.20) of perinatal mortality compared to non-migrants and a relative risk of 4.17 (95% confidence interval 3.51 ̶4.93) compared to documented migrants. Adjusting for maternal region of origin attenuated the results slightly. CONCLUSION: Being undocumented is strongly associated with perinatal mortality in the offspring. Disparities were not explained by maternal origin or maternal health factors, indicating that social determinants of health through delays in receiving adequate care and factors negatively influencing gestational length may be of importance.

Preeclampsia is a syndrome that continues to be a major contributor to maternal and neonatal mortality, especially in low-income countries. Low-dose aspirin reduces the risk of preeclampsia, but the mechanism is still unknown. Risk factors to identify women at risk of preeclampsia are based on clinical characteristics. Women identified as high-risk would benefit from aspirin treatment initiated, preferably at the end of the first trimester. Current efforts have largely focused on developing screening algorithms that incorporate clinical risk factors, maternal biomarkers, and uterine artery Doppler evaluated in the first trimester. However, most studies on preeclampsia are conducted in high-income settings, raising uncertainties about whether the information gained can be totally applied in low-resource settings. In low- and middle-income countries, lack of adequate antenatal care and late commencement of antenatal care visits pose significant challenges for both screening for preeclampsia and initiating aspirin treatment. Furthermore, the preventive effect of first-trimester screening based on algorithms and subsequent aspirin treatment is primarily seen for preterm preeclampsia, and reviews indicate minimal or no impact on reducing the risk of term preeclampsia. The lack of evidence regarding the effectiveness of aspirin in preventing term preeclampsia is a crucial concern, as 75% of women will develop this subtype of the syndrome. Regarding adverse outcomes, low-dose aspirin has been linked to a possible higher risk of postpartum hemorrhage, a condition as deadly as preeclampsia in many low- and middle-income countries. The increased risk of postpartum hemorrhage among women in low-income settings should be taken into consideration when discussing which pregnant women would benefit from the use of aspirin and the ideal aspirin dosage for preventing preeclampsia. In addition, women's adherence to aspirin during pregnancy is crucial for determining its effectiveness and complications, an aspect often overlooked in trials. In this review, we analyze the knowledge gaps that must be addressed to safely increase low-dose aspirin use in low- and middle-income countries, and we propose directions for future research.
RESUMO
Perinatal death, a global health problem, can be prevented with simple resuscitation interventions that help the baby breathe immediately at birth. Latter-day Saint Charities (LDSC) and Safa Sunaulo Nepal (SSN) implemented a program to scale-up Helping Babies Breathe (HBB) training in Karnali Province, Nepal from January 2020-February 2021. The interventions were implemented using a hybrid approach with on-site mentoring in the pre/post COVID period combined with remote support and monitoring during the COVID period. This paper reports overall changes in newborn outcomes in relation to the unique implementation approach used. A prospective cohort design was used to compare outcomes of birth cohorts in 16 public health facilities in the first and last three months of program implementation. Results showed significant decreases in intrapartum stillbirths (23%), and neonatal deaths within (27%) and after (41.3%) 24âhours of life. The scale-up of HBB training resulted in 557 providers receiving training and mentoring support during the program period, half trained during the COVID period. Increased practice sessions, review meetings and debriefing meetings were reported during the COVID period compared to pre/post COVID period. The evaluation is suggestive of the potential of a hybrid approach for improved perinatal outcomes and scaling-up of newborn resuscitation trainings in health system facing disruptions.
RESUMO
Most deliveries before 34 weeks of gestation occur in individuals with no previous history of preterm birth. Midtrimester cervical length assessment using transvaginal ultrasound is one of the best clinical predictors of spontaneous preterm birth. This Consult provides guidance for the diagnosis and management of a short cervix in an individual without a history of preterm birth. The following are Society for Maternal-Fetal Medicine recommendations: (1) we recommend that all cervical length measurements used to guide therapeutic recommendations be performed using a transvaginal approach and in accordance with standardized procedures as described by organizations such as the Perinatal Quality Foundation or the Fetal Medicine Foundation (GRADE 1C); (2) we recommend using a midtrimester cervical length of ≤25 mm to diagnose a short cervix in individuals with a singleton gestation and no previous history of spontaneous preterm birth (GRADE 1C); (3) we recommend that asymptomatic individuals with a singleton gestation and a transvaginal cervical length of ≤20 mm diagnosed before 24 weeks of gestation be prescribed vaginal progesterone to reduce the risk of preterm birth (GRADE 1A); (4) we recommend that treatment with vaginal progesterone be considered at a cervical length of 21 to 25 mm based on shared decision-making (GRADE 1B); (5) we recommend that 17-alpha hydroxyprogesterone caproate, including compounded formulations, not be prescribed for the treatment of a short cervix (GRADE 1B); (6) in individuals without a history of preterm birth who have a sonographic short cervix (10-25 mm), we recommend against cerclage placement in the absence of cervical dilation (GRADE 1B); (7) we recommend that cervical pessary not be placed for the prevention of preterm birth in individuals with a singleton gestation and a short cervix (GRADE 1B); and (8) we recommend against routine use of progesterone, pessary, or cerclage for the treatment of cervical shortening in twin gestations outside the context of a clinical trial (GRADE 1B).

OBJECTIVES: to describe the results of a pilot population-based perinatal mortality surveillance system, with regards to stillbirths; to study maternal, obstetric, and foetal characteristics, evaluating risk factors and understanding causes. DESIGN: a cross-sectional study was conducted on incident cases of stillbirths collected by the surveillance system from July 2017 to June 2019 in three Italian Regions (Lombardy, Tuscany, and Sicily). SETTING AND PARTICIPANTS: data on stillbirths, resulting from the in-hospital multidisciplinary audits, organised using the Significant Event Audit methodology, were analysed. According to the World Health Organization (WHO) definitions, the project identified stillbirths as foetuses born dead >=28 weeks of gestation. The WHO International Classification of Diseases-Perinatal Mortality was used to categorise the causes of foetal death. MAIN OUTCOMES MEASURES: maternal characteristics, obstetric and foetal findings were investigated. Unadjusted relative risks and 95% confidence intervals were computed with respect to the background population. Finally, causes of death and contributing maternal conditions have been considered. RESULTS: the maternity and neonatal units of the three participating Regions notified 520 stillbirths, of which 435 cases underwent to the multidisciplinary audit (83.7%); 40.0% of cases occurred in the gestational age range between 36 and 39 weeks. The risk of stillbirth was significantly increased in mothers with foreign citizenship (RR: 1.39; 95%CI: 1.13-1.71), multiple pregnancies (RR: 1.59; 95%CI 1.05-2.42), and pregnancies conceived with assisted reproductive technologies (RR: 2.15; 95%CI 1.45-3.19). The rate of congenital malformations was 6.0%. A diagnosis of foetal growth restriction was reported in 10.3% of cases, although the percentage of dead foetuses weighting <10° centile was at least twice in almost all gestational age periods. Post-mortem and placental histological examinations were carried out in more than 70% and more than 90% of cases, respectively. CONCLUSIONS: the implementation of a population-based surveillance system with high participation rate of maternity units and the use of universally accepted definitions could improve the identification of stillbirth avoidable risk factors and potentially modifiable predisposing maternal conditions, highlighting issues of perinatal assistance in need of improvement.

Background: A single umbilical artery (SUA) may coexist with a single anomaly or multiple congenital anomalies. Although anomalies associated with SUA can primarily cause high perinatal mortality, their clinical significance has not been evaluated. Objective: We investigated the relationship between the clinical features and the type or number of concurrent anomalies in neonates with SUA. Materials and Methods: In this cross-sectional study, 104 neonates with SUA were enrolled from January 2000 to December 2020 at Dongsan hospital, Daegu, South Korea. Data on the maternal history and the neonates demographic characteristics, clinical course, chromosomal analysis, and congenital anomalies, were collected. Results: Among the neonates with SUA included, 77 (74.0%) had one or more congenital anomalies; 66 (63.5%) were cardiac, 20 (19.2%) were genitourinary, 12 (11.5%) were gastrointestinal, 5 (4.8%) were central nervous system, 12 (11.5%) were skeletal, and 5 (4.8%) were facial anomalies. The number of concurrent anomalies ranged from 0-4. Neonates with SUA and concurrent gastrointestinal anomaly had a high incidence of initial positive ventilation, intubation, and inotropic drug use and lower Apgar score at 1 min and 5 min. 7 (6.7%) neonates with SUA died. Low birth weight (odds ratio = 6.16, p = 0.05), maternal multiparity (2.41, p = 0.13), gastrointestinal anomaly (5.06, p = 0.11), and initial cardiac resuscitation (7.77, p = 0.11) were risk factors for mortality in neonates with SUA. Conclusion: Neonates with SUA and concurrent gastrointestinal anomaly, low birth weight, maternal multiparity, and initial cardiac resuscitation had poor outcomes.
RESUMO
Background: The aim of this study was to detail incidence rates and relative risks for severe adverse perinatal outcomes by birthweight centile categories in a large Australian cohort of late preterm and term infants. Methods: This was a retrospective cohort study of singleton infants (≥34+0 weeks gestation) between 2000 and 2018 in Queensland, Australia. Study outcomes were perinatal mortality, severe neurological morbidity, and other severe morbidity. Categorical outcomes were compared using Chi-squared tests. Continuous outcomes were compared using t-tests. Multinomial logistic regression investigated the effect of birthweight centile on study outcomes. Findings: The final cohort comprised 991,042 infants. Perinatal mortality occurred in 1944 infants (0.19%). The incidence and risk of perinatal mortality increased as birthweight decreased, peaking for infants <1st centile (perinatal mortality rate 13.2/1000 births, adjusted Relative Risk Ratio (aRRR) of 12.96 (95% CI 10.14, 16.57) for stillbirth and aRRR 7.55 (95% CI 3.78, 15.08) for neonatal death). Severe neurological morbidity occurred in 7311 infants (0.74%), with the highest rate (19.6/1000 live births) in <1st centile cohort. There were 75,243 cases of severe morbidity (7.59% livebirths), with the peak incidence occurring in the <1st centile category (12.3% livebirths). The majority of adverse outcomes occurred in infants with birthweights between 10 and 90th centile. Almost 2 in 3 stillbirths, and approximately 3 in 4 cases of neonatal death, severe neurological morbidity or other severe morbidity occurred within this birthweight range. Interpretation: Although the incidence and risk of perinatal mortality, severe neurological morbidity and severe morbidity increased at the extremes of birthweight centiles, the majority of these outcomes occurred in infants that were apparently "appropriately grown" (i.e., birthweight 10th-90th centile).

RESUMO
AIM: In Japan, unlike Western countries, tocolytic agents are administered in long-term protocols to treat threatened preterm labor. Evaluating the side effects of this practice is crucial. We examined whether ritodrine hydrochloride had been administered in cases of maternal death, aiming to investigate any relationship between ritodrine administration and maternal death. METHODS: This retrospective cohort study used reports of maternal deaths from multiple institutions in Japan between 2010 and 2020. Data on the reported cases were retrospectively analyzed, and data on the route of administration, administered dose, and clinical findings, including causes of maternal death, were extracted. The amount of tocolytic agents was compared between maternal deaths with ritodrine administration and those without. RESULTS: A total of 390 maternal deaths were reported to the Maternal Death Exploratory Committee in Japan during the study period. Ritodrine hydrochloride was administered in 32 of these cases. The frequencies (n) and median doses (range) of oral or intravenous ritodrine hydrochloride were 34.4% (11) and 945 (5-2100) mg and 84.4% (27) and 4032 (50-18 680) mg, respectively. Frequencies of perinatal cardiomyopathy, cerebral hemorrhage, diabetic ketoacidosis, and pulmonary edema as causes of maternal death were significantly higher with ritodrine administration than without it. CONCLUSIONS: Our results suggest a relationship between long-term administration of ritodrine hydrochloride and an increased risk of maternal death due to perinatal cardiomyopathy, cerebral hemorrhage, diabetic ketoacidosis, and pulmonary edema. In cases where ritodrine should be administered to prevent preterm labor, careful management and monitoring of maternal symptoms are required.
