SARS-CoV-2 infection by trimester of pregnancy and adverse perinatal outcomes: a Mexican retrospective cohort study.

OBJECTIVE: Conflicting evidence for the association between COVID-19 and adverse perinatal outcomes exists. This study examined the associations between maternal COVID-19 during pregnancy and adverse perinatal outcomes including preterm birth (PTB), low birth weight (LBW), small-for-gestational age (SGA), large-for-gestational age (LGA) and fetal death; as well as whether the associations differ by trimester of infection. DESIGN AND SETTING: The study used a retrospective Mexican birth cohort from the Instituto Mexicano del Seguro Social (IMSS), Mexico, between January 2020 and November 2021. PARTICIPANTS: We used the social security administrative dataset from IMSS that had COVID-19 information and linked it with the IMSS routine hospitalisation dataset, to identify deliveries in the study period with a test for SARS-CoV-2 during pregnancy. OUTCOME MEASURES: PTB, LBW, SGA, LGA and fetal death. We used targeted maximum likelihood estimators, to quantify associations (risk ratio, RR) and CIs. We fit models for the overall COVID-19 sample, and separately for those with mild or severe disease, and by trimester of infection. Additionally, we investigated potential bias induced by missing non-tested pregnancies. RESULTS: The overall sample comprised 17 340 singleton pregnancies, of which 30% tested positive. We found that those with mild COVID-19 had an RR of 0.89 (95% CI 0.80 to 0.99) for PTB and those with severe COVID-19 had an RR of 1.53 (95% CI 1.07 to 2.19) for LGA. COVID-19 in the first trimester was associated with fetal death, RR=2.36 (95% CI 1.04, 5.36). Results also demonstrate that missing non-tested pregnancies might induce bias in the associations. CONCLUSIONS: In the overall sample, there was no evidence of an association between COVID-19 and adverse perinatal outcomes. However, the findings suggest that severe COVID-19 may increase the risk of some perinatal outcomes, with the first trimester potentially being a high-risk period.

Fetal aortic isthmus Doppler assessment to predict the adverse perinatal outcomes associated with fetal growth restriction: systematic review and meta-analysis.

PURPOSE: Fetal growth restriction (FGR) management and delivery planning is based on a multimodal approach. This meta-analysis aimed to evaluate the prognostic accuracies of the aortic isthmus Doppler to predict adverse perinatal outcomes in singleton pregnancies with FGR. METHODS: PubMed, EMBASE, the Cochrane Library, ClinicalTrials.gov and Google scholar were searched from inception to May 2021, for studies on the prognostic accuracy of anterograde aortic isthmus flow compared with retrograde aortic isthmus flow in singleton pregnancy with FGR. The meta-analysis was registered on PROSPERO and was assessed according to PRISMA and Newcastle-Ottawa Scale. DerSimonian and Laird's random-effect model was used for relative risks, Freeman-Tukey Double Arcsine for pooled estimates and exact method to stabilize variances and CIs. Heterogeneity was quantified using I2 statistics. RESULTS: A total of 2933 articles were identified through the electronic search, of which 6 studies (involving 240 women) were included. The quality evaluation of studies revealed an overall acceptable score for study group selection and comparability and substantial heterogeneity. The risk of perinatal death was significantly greater in fetuses with retrograde Aortic Isthmus blood flow, with a RR of 5.17 (p value 0.00001). Similarly, the stillbirth rate was found to have a RR of 5.39 (p value 0.00001). Respiratory distress syndrome had a RR of 2.64 (p value = 0.03) in the group of fetuses with retrograde Aortic Isthmus blood flow. CONCLUSION: Aortic Isthmus Doppler study may add information for FGR management. However, additional clinical trial are required to assess its applicability in clinical practice.

Assessment of Severity of Long QT Syndrome Phenotype and Risk of Fetal Death.

BACKGROUND: It has been postulated that long QT syndrome (LQTS) can cause fetal loss through putative adverse effects of the channelopathy on placenta and myometrial function. The authors aimed to describe the fetal death rate in a population of pregnant women with long QT syndrome and investigate whether women with more severe phenotype had worse fetal outcomes. METHODS AND RESULTS: The authors retrospectively evaluated fetal outcomes of 64 pregnancies from 23 women with long QT syndrome followed during pregnancy in a tertiary pregnancy and heart disease program. Thirteen of 64 pregnancies (20%) resulted in a fetal loss, 12 miscarriages (19%), and 1 stillbirth (1.6%). Baseline maternal characteristics, including age and use of ß-blockers, did not differ between women who experienced a fetal death or not. Maternal corrected QT interval (QTc) was significantly longer in pregnancies that resulted in fetal death compared with live births (median, 518 ms [interquartile range (IQR), 482-519 ms] versus 479 ms [IQR, 454-496 ms], P<0.001). Mothers treated with ß-blockers had babies born at term with lower birth weight compared with untreated women (2973±298 g versus 3470±338 g, P=0.002). In addition, the birth weight of babies born at term to treated women with QTc >500 ms was significantly lower compared with women with QTc <500 ms (2783±283 g versus 3084±256 g, P=0.029). CONCLUSIONS: Women with long QT syndrome with more severe phenotypes have a higher incidence of fetal death. Maternal QTc is longer in pregnancies that result in fetal loss, and the birth weight of babies born to patients taking ß-blockers with a QTc >500 ms is lower, suggesting that patients with more marked phenotype may experience worse fetal outcomes.

Fetal death and its association with indicators of social inequality: 20-year analysis in Tacna, Peru.

OBJECTIVE: The aim of this study was to evaluate the rates of fetal mortality in a Peruvian hospital between 2001 and 2020 and to investigate the association of indicators of social inequality (such as access to prenatal care and education) with fetal mortality. METHODOLOGY: We conducted a retrospective cohort study, including all pregnant women who attended a Peruvian hospital between 2001 and 2020. We collected data from the hospital's perinatal computer system. We used Poisson regression models with robust variance to assess the associations of interest, estimating adjusted relative risks (aRR) and their 95% confidence intervals (95% CI). RESULTS: We analyzed data from 67,908 pregnant women (median age: 26, range: 21 to 31 years). Of these, 58.3% had one or more comorbidities; the most frequent comorbidities were anemia (33.3%) and urinary tract infection (26.3%). The fetal mortality ratio during the study period was 0.96%, with the highest rate in 2003 (13.7 per 1,000 births) and the lowest in 2016 (6.1 per 1,000 births), without showing a marked trend. Having less than six (aRR: 4.87; 95% CI: 3.99-5.93) or no (aRR: 7.79; 6.31-9.61) prenatal care was associated with higher fetal mortality compared to having six or more check-ups. On the other hand, higher levels of education, such as secondary education (aRR: 0.73; 0.59-0.91), technical college (aRR: 0.63; 0.46-0.85), or university education (aRR: 0.38; 0.25-0.57) were associated with a lower risk of fetal death compared to having primary education or no education. In addition, a more recent year of delivery was associated with lower fetal mortality. CONCLUSION: Our study presents findings of fetal mortality rates that are comparable to those observed in Peru in 2015, but higher than the estimated rates for other Latin American countries. A more recent year of delivery was associated with lower fetal mortality, probably due to reduced illiteracy and increased access to health care between 2000 and 2015. The findings suggest a significant association between indicators of social inequality (such as access to prenatal care and education) with fetal mortality. These results emphasize the critical need to address the social and structural determinants of health, as well as to mitigate health inequities, to effectively reduce fetal mortality.

Intervenções psicológicas necessárias: a prática como residente no serviço de medicina fetal / Necessary psychological interventions: the practice as a resident in the fetal medicine service / Intervenciones psicológicas necesarias: la práctica como residente en el servicio de medicina fetal

Com os avanços tecnológicos e o aprimoramento da prática médica via ultrassonografia, já é possível detectar possíveis problemas no feto desde a gestação. O objetivo deste estudo foi analisar a prática do psicólogo no contexto de gestações que envolvem riscos fetais. Trata-se de um estudo qualitativo sob formato de relato de experiência como psicólogo residente no Serviço de Medicina Fetal da Maternidade Escola da Universidade Federal do Rio de Janeiro (UFRJ).

Face to the technological advances and the improvement of medical practice via ultrasound, it is already possible to detect possible problems in the fetus since pregnancy. The objective of this study was to analyze the psychologist's practice in the context of pregnancies which involve fetal risks. It is a qualitative study based on an experience report as a psychologist trainee at the Fetal Medicine Service of the Maternity School of UFRJ. The records, based on the participant observation and field diary, were analyzed in two thematic axes: 1) psychological interventions in the teamwork in the prenatal attendance, ultrasound examination and amniocentesis procedure; and 2) psychological interventions in cases of babies incompatible to the life. The results indicated that the psychologist in this service is essential to work in a multidisciplinary way at the prenatal care for high fetal risk pregnancies. Furthermore, the resident's preceptorship is relevant to their education and training for professional performance in the field of Perinatal Psychology.(AU)

Factors associated with severe maternal, fetuses and neonates' outcomes in a university hospital in Rio de Janeiro State / Fatores associados a desfechos graves maternos, fetais e neonatais em um hospital universitário do estado do Rio de Janeiro

Abstract Objectives: to estimate the burden of parturients, fetuses and neonate's severe morbidity and mortality and investigate the association between maternal and their conceptus outcomes. Methods: retrospective cohort of 546 parturients and their conceptus in a university hospital, reference for high-risk pregnancy, in the metropolitan region II of Rio de Janeiro State from 2015 to 2017. We classified parturients according to obstetric morbidity (OM) in direct, indirect, or mixed, and their outcomes as: 1) no severity, 2) severe complication (SC), 3) critical intervention/Intensive Care Unit, and 4) greater severity -maternal near-miss (MNM) or death. We evaluated the conceptus as neonatal near-miss (NNM) and fetal and neonatal deaths. We estimated morbimortality indicators and associated factors (multinomial logistic regression). Results: OM was frequent: 29.3% indirect, 22.3% direct, and 15.8% mixed. There were eight cases of NMM, seven with direct MO. Among the conceptus: 7.5% were NNM cases and 4.4%, deaths. The risk of severe maternal outcomes was 16.8 and neonatal, 102.6/1000 live births. Mixed race, inadequate prenatal care, CG and NMM/death, were associated with NNM. Inadequate prenatal care and maternal NM/death were associated with conceptus deaths. Conclusion: even in a reference unit, sociodemographic, and health care inequalities negatively affect mothers and, consequently, their children.

Resumo Objetivos: estimar a carga de morbidade grave e mortalidade em parturientes, fetos e neonatos e investigar a associação entre os desfechos maternos e de seus conceptos. Métodos: coorte retrospectiva de 546 parturientes e seus conceptos no hospital universitário referência para gravidez de alto risco da região metropolitana II do estado do Rio de Janeiro (ERJ), de 2015 a 2017. Classificamos as parturientes segundo morbidade obstétrica (MO) em direta, indireta e mista, e seus desfechos como: 1) sem gravidade, 2) complicação grave (CG), 3) intervenção crítica/ Unidade Terapia Intensiva e 4) maior gravidade-near miss materno (NMM) ou óbito. Avaliamos os conceptos quanto a near miss neonatal (NMN), óbitos fetais e neonatais. Estimamos indicadores de morbimortalidade, e fatores de associação (regressão logística multinomial). Resultados: MO foi frequente: 29,3% indiretas, 22,3% diretas e 15,8% mista. Ocorreram oito casos de NMM, sete com MO direta. Entre os conceptos,7,5% foram casos de NMN e 4,4%, óbitos. O risco de desfecho grave materno foi 16,8 e neonatal, 102,6 p/1000 nascidos vivos. Estiveram associados ao NMN: cor parda, pré-natal inadequado, CG e NMM/óbito; e ao óbito do concepto: pré-natal inadequado e NMM/óbito. Conclusão: mesmo em situação de referência, desigualdades sociodemográficas e assistenciais afetam negativamente mães e, consequentemente, seus conceptos.

Refreshing the Perinatal Periods of Risk: A New Reference Group and Nationwide Large-County-Level Analyses.

INTRODUCTION: The Perinatal Periods of Risk approach (PPOR) is designed for use by communities to assess and address the causes of high fetal-infant mortality rates using vital records data. The approach is widely used by local health departments and their community and academic partners to inform and motivate systems changes. PPOR was developed and tested in communities based on data years from 1995 to 2002. Unfortunately, a national reference group has not been published since then, primarily due to fetal death data quality limitations. METHODS: This paper assesses data quality and creates a set of unbiased national reference groups using 2014-2016 national vital records data. Phase 1 and Phase 2 analytic methods were used to divide excess mortality into six components and create percentile plots to summarize the distribution of 100 large US counties for each component. RESULTS: Eight states with poor fetal death data quality were omitted from the reference groups to reduce bias due to missing maternal demographic information. There are large Black-White disparities among reference groups with the same age and education restrictions, and these vary by component. PPOR results vary by region, maternal demographics, and county. The magnitude of excess mortality components varies widely across US counties. DISCUSSION: New national reference groups will allow more communities to do PPOR. Percentile plots of 100 large US counties provide an additional benchmark for new communities using PPOR and help emphasize problem areas and potential solutions.

Ultrasound assessment of twin reversed arterial perfusion sequence for the prediction of adverse pregnancy outcomes in the first trimester.

OBJECTIVE: To investigate twin reversed arterial perfusion (TRAP) sequence for the prediction of TRAP-related adverse pregnancy outcomes at the gestational age of 11-14 weeks. METHODS: Pregnant women in the first trimester diagnosed with TRAP were recruited at West China Second University Hospital from January 2015 to June 2018. Systematic screening for the pump twin's crown-rump length (CRL) and acardiac twin's upper pole-rump length (URL) was conducted using ultrasonic detection. The (CRL - URL)/CRL and URL/CRL ratios were used to assess the pregnancy outcomes for the pump twin. Twenty-one pregnant women aged 21-39 years with a gestation of 11-14 weeks were recruited. RESULTS: TRAP was diagnosed on average (± standard deviation (SD)) at pregnancy week 13.1 ± 0.18. The pump twins' mean (± SD) CRL was 6.65 ± 1.1 cm. The incidence of intrauterine death for the pump twins was 19.0% (n = 4), the miscarriage rate was 14.3% (n = 3), and the live birth rate was 66.7% (n = 14). The (CRL - URL)/CRL ratios between the nonsurvival (intrauterine death and miscarriage) and survival groups significantly differed (0.33 ± 0.08 vs. 0.58 ± 0.08, p < 0.05). Similarly, the URL/CRL ratios between the nonsurvival and survival groups significantly differed (0.67 ± 0.08 vs. 0.42 ± 0.08, p < 0.05). CONCLUSION: The (CRL - URL)/CRL and URL/CRL ratios were valuable indicators for determining pregnancy outcomes of pump twins with TRAP at an early gestational age.

Third trimester intrauterine fetal death: proposal for the assessment of the chronology of umbilical cord and placental thrombosis.

The timing of umbilical cord and placental thrombosis in the third trimester intrauterine fetal death (TT-IUFD) may be fundamental for medico-legal purposes, when it undergoes medical litigation due to the absence of risk factors. Authors apply to human TT-IUFD cases a protocol, which includes histochemistry and immunohistochemistry (IHC) for the assessment of thrombi's chronology. A total of 35 thrombi of umbilical cord and/or placenta were assessed: 2 in umbilical artery, 6 in umbilical vein, 15 in insertion, 10 in chorionic vessels, 1 in fetal renal vein, 1 in fetal brachiocephalic vein. Thrombi's features were evaluated with hematoxylin-eosin, Picro-Mallory, Von Kossa, Perls, and immunohistochemistry for CD15, CD68, CD31, CD61, and Smooth Muscle Actin. The estimation of the age of the thrombi was established by applying neutrophils/macrophages ratio taking into consideration, according to literature, the presence of hemosiderophagi, calcium deposition, and angiogenesis. To estimate an approximate age of fresh thrombi (< 1 day), a non-linear regression model was tested. Results were compared to maternal risk factors, fetal time of death estimated at autopsy, mechanism, and cause of death. Our study confirms that the maternal risk factors for fetal intrauterine death and the pathologies of the cord, followed by those of the placental parenchyma, are the conditions that are most frequently associated with the presence of thrombi. Results obtained with histological stainings document that the neutrophile/macrophage ratio is a useful tool for determining placental thrombi's age. Age estimation of thrombi on the first day is very challenging; therefore, the study presented suggests the N/M ratio as a parameter to be used, together with others, i.e., hemosiderophagi, calcium deposition, and angiogenesis, for thrombi's age determination, and hypothesizes that its usefulness regards particularly the first days when all other parameters are negative.

[Avoidability of fetal deaths: reflections on the Brazilian List of Avoidable Causes of Deaths through interventions by the Brazilian Unified National Health System]. / Evitabilidade de óbitos fetais: reflexões sobre a Lista Brasileira de Causas de Mortes Evitáveis por intervenção do Sistema Único de Saúde.

Although the Brazilian List of Avoidable Causes of Deaths (LBE in Portuguese), in its version for children under 5 years of age (LBE < 5), does not include stillbirths, some studies have used the list with or without adaptations. We present a proposal for adaptation of the LBE for stillbirths (LBE-OF in Portuguese) and the results of its application to stillbirths in the State of Rio de Janeiro, Brazil, in 2018, compared to the results with LBE < 5. We reviewed the categories from the 10th revision of the International Classification of Diseases (ICD-10) in the LBE < 5 and reassigned them in the avoidability groups, according to time of death in relation to delivery and the causes consistent with stillbirths. Conditions that did not elucidate the determinants of death were allocated as ill-defined causes. Stillbirths in the State of Rio de Janeiro, selected from the databases of the Mortality Information System (SIM in Portuguese), were classified according to LBE-OF and LBE < 5. When classifying the 2,585 stillbirths that occurred in the State of Rio de Janeiro in 2018, we found that according to LBE < 5, there were predominantly causes "reducible by adequate care in labor and delivery" (42.9%), while according to LBE-OF, the most frequent causes were "reducible by adequate care for during pregnancy" (43.6%). Ill-defined causes ranked second according to the LBE-OF (35.4%) and third according to LBE < 5. Some 30% of stillbirths changed groups and subgroups of avoidability, showing greater consistency with the profile of obstetric care. Although identifying a higher percentage of ill-defined causes, the LBE-OF is more consistent with the pathophysiology of fetal deaths. The inclusion of stillbirths in the SIM would be a positive step in monitoring and upgrading the investigation of causes of fetal death.

Apresentamos uma proposta de adaptação da LBE para óbitos fetais (LBE-OF) e os resultados de sua aplicação aos óbitos fetais no Estado do Rio de Janeiro, Brasil, em 2018, comparados aos da LBE < 5. Revisamos as categorias da 10ª revisão da Classificação Internacional de Doenças (CID-10) presentes na LBE < 5 e as realocamos nos grupos de evitabilidade, segundo momento do óbito em relação ao parto e as causas condizentes com óbitos fetais. Condições que não esclarecem os determinantes do óbito foram alocadas como causas mal definidas. Óbitos fetais no Estado do Rio de Janeiro - selecionados das bases do Sistema de Informações sobre Mortalidade (SIM) - foram classificados segundo LBE-OF e a LBE < 5. Ao classificar os 2.585 óbitos fetais do Estado do Rio de Janeiro ocorridos em 2018, observou-se que, segundo a LBE < 5, predominariam causas "reduzíveis por adequada atenção ao parto" (42,9%), já pela LBE-OF, aquelas "reduzíveis por adequada atenção à mulher na gestação" foram as mais frequentes (43,6%). As causas mal definidas ocuparam a segunda posição segundo a LBE-OF (35,4%) e a terceira posição segundo LBE < 5. Cerca de 30% dos óbitos fetais mudaram de grupos e subgrupos de evitabilidade, mostrando maior coerência com o perfil de atenção obstétrica. Embora identificando um maior percentual de causas mal definidas, a LBE-OF coaduna-se mais com a fisiopatologia dos óbitos fetais. Sua inserção no SIM avançaria no sentido de monitorar e qualificar a investigação de causas de morte fetal.

A pesar de que la Lista Brasileña de Causas de Muerte Evitables (LBE), en su versión para niños menores de 5 años (LBE < 5), no contemple los óbitos fetales, algunos estudios la utilizaron sin o con pocas adaptaciones. Presentamos una propuesta de adaptación de la LBE para óbitos fetales (LBE-OF) y los resultados de su aplicación a óbitos fetales en el Estado de Rio de Janeiro, Brasil, en 2018, comparados con los de la LBE < 5. Revisamos las categorías de la 10ª revisión de la Clasificación Internacional de Enferemedades (CIE-10) presentes en la LBE < 5, y las asignamos en los grupos de evitabilidad, según el momento del óbito, en relación con el parto y las causas acordes con óbitos fetales. Las condiciones que no aclararon los determinantes del óbito fueron asignadas como causas mal definidas. Los óbitos fetales del Estado de Río de Janeiro -seleccionados de las bases del Sistema de Información sobre Mortalidad (SIM)- se clasificaron según el LBE-OF y la LBE < 5. Al clasificar los 2.585 óbitos fetales del Estado de Rio de Janeiro ocurridos en 2018, se observó que, según la LBE < 5 años, predominarían causas "reducibles por una adecuada atención al parto" (42,9%), mientras que por la LBE-OF, aquellas "reducibles por una adecuada atención a la mujer en la gestación" fueron las más frecuentes (43,6%). Las causas mal definidas ocuparon la segunda posición según la LBE-OF (35,4%), y la tercera posición según LBE < 5. Cerca de un 30% de los óbitos fetales cambiaron de grupos y subgrupos de evitabilidad, mostrando una mayor coherencia con el perfil de atención obstétrica. A pesar de haberse identificado un mayor porcentaje de causas mal definidas, la LBE-OF es más compatible con la fisiopatología de los óbitos fetales. Su inserción en el SIM avanzaría en el sentido de monitorear y calificar la investigación de causas de muerte fetal.

Customized versus Population Growth Standards for Morbidity and Mortality Risk Stratification Using Ultrasonographic Fetal Growth Assessment at 22 to 29 Weeks' Gestation.

OBJECTIVE: The aim of study is to compare the performance of ultrasonographic customized and population fetal growth standards for prediction adverse perinatal outcomes. STUDY DESIGN: This was a secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, in which l data were collected at visits throughout pregnancy and after delivery. Percentiles were assigned to estimated fetal weights (EFWs) measured at 22 to 29 weeks using the Hadlock population standard and a customized standard (www.gestation.net). Areas under the curve were compared for the prediction of composite and severe composite perinatal morbidity using EFW percentile. RESULTS: Among 8,701 eligible study participants, the population standard diagnosed more fetuses with fetal growth restriction (FGR) than the customized standard (5.5 vs. 3.5%, p < 0.001). Neither standard performed better than chance to predict composite perinatal morbidity. Although the customized performed better than the population standard to predict severe perinatal morbidity (areas under the curve: 0.56 vs. 0.54, p = 0.003), both were poor. Fetuses considered FGR by the population standard but normal by the customized standard had morbidity rates similar to fetuses considered normally grown by both standards.The population standard diagnosed FGR among black women and Hispanic women at nearly double the rate it did among white women (p < 0.001 for both comparisons), even though morbidity was not different across racial/ethnic groups. The customized standard diagnosed FGR at similar rates across groups. Using the population standard, 77% of FGR cases were diagnosed among female fetuses even though morbidity among females was lower (p < 0.001). The customized model diagnosed FGR at similar rates in male and female fetuses. CONCLUSION: At 22 to 29 weeks' gestation, EFW percentile alone poorly predicts perinatal morbidity whether using customized or population fetal growth standards. The population standard diagnoses FGR at increased rates in subgroups not at increased risk of morbidity and at lower rates in subgroups at increased risk of morbidity, whereas the customized standard does not.

Understanding staff views and experiences of a clinical practice change to reduce stillbirth in South Asian women: A cross-sectional survey.

BACKGROUND: In July 2017, Victoria's largest maternity service implemented a new clinical practice guideline to reduce the rates of term stillbirth in women of South Asian background. AIM: To capture the views and experiences of clinical staff following the implementation of the new clinical guideline. METHODS: Cross sectional survey of clinical staff providing maternity care in August 2018, 12 months post implementation. Staff were asked to provide their agreement with ten statements assessing: perceived need for the guideline, implementation processes, guideline clarity, and clinical application. Open-ended questions provided opportunities to express concerns and offer suggestions for improvement. The frequency of responses to each question were tabulated. Open ended responses were grouped together to identify themes. FINDINGS: A total of 120 staff completed the survey, most (n=89, 74%) of whom were midwives. Most staff thought the rationale (n=95, 79%), the criteria for whom they applied (83%, n=99), and the procedures and instructions within the guideline were clear (74%, n=89). Staff reported an increase in workload (72%, n=86) and expressed concerns related to rationale and evaluation of the guidelines, lack of education for both staff and pregnant South Asian women, increased workload and insufficient resources, patient safety and access to care. Challenges relating to shared decision making and communicating with women whose first language is not English were also identified. DISCUSSION: This study has identified key barriers to and opportunities for improving implementation and highlighted additional challenges relating to new clinical guidelines which focus on culturally and linguistically diverse women.

When classifying the 2,585 stillbirths that occurred in the State of Rio de Janeiro in 2018, we found that according to LBE < 5, there were predominantly causes "reducible by adequate care in labor and delivery" (42.9%), while according to LBE-OF, the most frequent causes were "reducible by adequate care for during pregnancy" (43.6%). Ill-defined causes ranked second according to the LBE-OF (35.4%) and third according to LBE < 5. Some 30% of stillbirths changed groups and subgroups of avoidability, showing greater consistency with the profile of obstetric care. Although identifying a higher percentage of ill-defined causes, the LBE-OF is more consistent with the pathophysiology of fetal deaths. The inclusion of stillbirths in the SIM would be a positive step in monitoring and upgrading the investigation of causes of fetal death.

Resumo: A pesar de que la Lista Brasileña de Causas de Muerte Evitables (LBE), en su versión para niños menores de 5 años (LBE < 5), no contemple los óbitos fetales, algunos estudios la utilizaron sin o con pocas adaptaciones. Presentamos una propuesta de adaptación de la LBE para óbitos fetales (LBE-OF) y los resultados de su aplicación a óbitos fetales en el Estado de Rio de Janeiro, Brasil, en 2018, comparados con los de la LBE < 5. Revisamos las categorías de la 10ª revisión de la Clasificación Internacional de Enferemedades (CIE-10) presentes en la LBE < 5, y las asignamos en los grupos de evitabilidad, según el momento del óbito, en relación con el parto y las causas acordes con óbitos fetales. Las condiciones que no aclararon los determinantes del óbito fueron asignadas como causas mal definidas. Los óbitos fetales del Estado de Río de Janeiro -seleccionados de las bases del Sistema de Información sobre Mortalidad (SIM)- se clasificaron según el LBE-OF y la LBE < 5. Al clasificar los 2.585 óbitos fetales del Estado de Rio de Janeiro ocurridos en 2018, se observó que, según la LBE < 5 años, predominarían causas "reducibles por una adecuada atención al parto" (42,9%), mientras que por la LBE-OF, aquellas "reducibles por una adecuada atención a la mujer en la gestación" fueron las más frecuentes (43,6%). Las causas mal definidas ocuparon la segunda posición según la LBE-OF (35,4%), y la tercera posición según LBE < 5. Cerca de un 30% de los óbitos fetales cambiaron de grupos y subgrupos de evitabilidad, mostrando una mayor coherencia con el perfil de atención obstétrica. A pesar de haberse identificado un mayor porcentaje de causas mal definidas, la LBE-OF es más compatible con la fisiopatología de los óbitos fetales. Su inserción en el SIM avanzaría en el sentido de monitorear y calificar la investigación de causas de muerte fetal.

Could a multidisciplinary regional audit identify avoidable factors and delays that contribute to stillbirths? A retrospective cohort study.

BACKGROUND: The annual rate of stillbirth in Sweden has remained largely unchanged for the past 30 years. In Sweden, there is no national audit system for stillbirths. The aim of the study was to determine if a regional multidisciplinary audit could help in identifying avoidable factors and delays associated with stillbirths. METHODS: Population-based retrospective cohort study. SETTINGS: Six labour wards in Stockholm County. PARTICIPANTS: Women delivering a stillbirth > 22 weeks of gestation in Stockholm during 2017. INTERVENTION: A multidisciplinary team was convened. Each team member independently assessed the medical chart of each case of stillbirth regarding causes and preventability, level of delay, the standard of healthcare provided, the investigation of maternal/foetal diseases and if any recommendations were given for the next pregnancy. A decision was based on the agreement of all five members. If no agreement was reached, a reassessment of the case was done and the medical record was scrutinized again until a mutual decision was made. Primary outcomes: The frequency of probably/possibly preventable factors associated with a stillbirth and the level of delay (patient/caregiver). SECONDARY OUTCOMES: The causes of death, the standard of antenatal/intrapartum/postpartum care, whether a summary of possible causes of the stillbirth was made and if any plans for future pregnancies were noted. RESULTS: Thirty percent of the stillbirths were assessed as probably/possibly preventable. More frequent ultrasound/clinical check-ups, earlier induction of labour and earlier interventions in line with current guidelines were identified as possibly preventable factors. A possibly preventable stillbirth was more common among non-Swedish-speaking women (p = 0.03). In 15% of the cases, a delay by the healthcare system was identified. Having multiple caregivers, absence of continuity in terms of attending the antenatal clinic and not following the basic monitoring program for antenatal care were also identified as risk factors for a delay. CONCLUSION: A national/regional multidisciplinary audit group retrospectively identified factors associated with stillbirth. Access to good translation services or a more innovative approach to the problem regarding communication with mothers could be an important factor to decrease possible patient delays contributing to stillbirths.

Trends in Appendicitis Among Pregnant Women, the Risk for Cardiac Arrest, and Maternal-Fetal Mortality.

BACKGROUND: Appendicitis is the most common extra-uterine surgical emergency requiring immediate intervention during pregnancy. However, risks for mortality and morbidity among pregnant women with appendicitis remain poorly understood. This study was conducted to determine the temporal trends of appendicitis in pregnant women, and to calculate the risk of maternal-fetal mortality and near-miss marker (i.e., cardiac arrest) among pregnant women in general, and by race/ethnicity. METHODS: We conducted this retrospective study using data from the Nationwide Inpatient Sample (NIS) from January 1, 2002, through December 31, 2015. Joinpoint regression was used to estimate and describe temporal changes in the rates of all and acute appendicitis during the 14-year study period. We also estimated the risk of cardiac arrest, maternal, and fetal mortality among mothers of various racial/ethnic groups with a diagnosis of acute appendicitis. Within each group, patients without acute appendicitis were the referent category. RESULTS AND CONCLUSIONS: Out of the 58 million pregnancy hospitalizations during the study period, 63,145 cases (10.74 per 10,000 hospitalizations) were for acute appendicitis. There was a 5% decline (95% CI: - 5.1, - 5.0) in the rate of appendicitis hospitalizations over the period of the study. After adjusting for covariates, pregnant mothers with acute appendicitis had increased likelihood when compared to those without acute appendicitis to suffer fetal loss (OR: 2.05, 95% CI: 1.85-2.28) and nearly fivefold increase for inpatient maternal death. In conclusion, appendicitis during pregnancy remains an important cause of in-hospital maternal-fetal mortality overall and regardless of race/ethnicity.

Labour admission assessment results of index pregnancy as predictors of intrapartum stillbirth in public health facilities of Addis Ababa: A case-control study.

BACKGROUND: Approximately one-third of the global stillbirth burden occurs during intrapartum period. The ability to assess obstetric parameters including effacement, dilatation, uterine contraction, decent, rupture of the uterus, and moulding of the foetal head are among the essential competencies required by obstetric service providers admitting women for labour in health facilities. Misdiagnosis of these conditions could result in unnecessary obstetric interventions and unfavourable obstetric outcomes including intrapartum stillbirth. This study aimed to assess associations between missed diagnosis plus complication of labour on admission and intrapartum stillbirth. METHODS: A case-control study using primary data from chart review of medical records of women who experienced intrapartum stillbirth in 20 public health centres and three public hospitals of Addis Ababa between 01 July 2010 and 30 June 2015 was conducted. Data were collected from charts of all cases meeting the inclusion criteria. Medical records of women with livebirths were randomly selected and reviewed from each public health facilities in two to one (2:1) control to case ratio. Accordingly, 728 cases of stillbirth out of 1,056 charts met the inclusion criteria whereas 1,551 controls out of 1,705 were also considered in the study. RESULTS: Proportionally, more women in the stillbirth group (39.4%) than in the livebirth group (30.2%) experienced ruptured membrane on admission, with the difference being statistically significant (OR 1.7, 95% CI 1.37-2.03). Significantly higher proportion of women in the intrapartum stillbirth group experienced FRH lower than 110/min, a result suggestive of foetal distress on admission. Proportionally, more women in the intrapartum stillbirth group (14.5%) than in the livebirth group (4.5%) had breech foetal presentation on admission for labour, the difference being statistically significant (aOR 3.26 95% CI 1.93-5.50). Intrapartum stillbirth was slightly higher among women with cervical dilatation 4cm or more on admission (OR 1.2, 95% CI 1.00-1.45). This could be owing to delay in seeking obstetric care or misdiagnosis of the condition, a situation that seeks more rigorous study to determine the underlying causal links. Diagnosis of foetal member was missed among more cases than controls where the difference was statistically significant (aOR 1.51, CI 1.03-2.19). CONCLUSION: Low FHR, non-vertex foetal presentations and ruptured cervical membrane were predictors of intrapartum stillbirth. Health facilities could avert unnecessary foetal loss by undertaking timely actions to manage obstetric emergencies on admission to labour.

Intimate partner violence during pregnancy and risk of fetal and neonatal death: a meta-analysis with socioeconomic context indicators.

OBJECTIVE: The objective of the study was to summarize the results from observational studies examining the risk of fetal and neonatal death (perinatal death) as a function of the experience of intimate partner violence during pregnancy and examine the influence of socioeconomic context indicators on this association. DATA SOURCES: Bibliographic searches were conducted in PubMed, EMBASE, CINAHL, and LILACS until March 2019. STUDY ELIGIBILITY CRITERIA: We considered observational studies that provided data on the association between intimate partner violence during pregnancy and perinatal death. STUDY APPRAISAL AND SYNTHESIS METHODS: Information collected included study characteristics, type, and prevalence of intimate partner violence and the reported association between intimate partner violence and perinatal death. Quality of the included studies was assessed using the Newcastle-Ottawa scale. Two reviewers independently conducted all review procedures; disagreements were resolved by a third reviewer. Meta-analyses were conducted based on the specific type of intimate partner violence (physical, psychological, sexual, unspecified) and also based on any type of intimate partner violence, considering 1 effect size per study, regardless of the type of intimate partner violence analyzed. Meta-regression analyses were performed to assess the possible effects of socioeconomic context. The proportion of deaths attributable to the exposure of intimate partner violence based on the crude data from the 3 cohort studies available also was calculated. RESULTS: Seventeen studies were included. The random-effects model showed a statistically significant increase in the odds of perinatal death among women exposed to unspecified intimate partner violence (odds ratio, 3.18; 95% confidence interval, 1.88-5.38), physical intimate partner violence (odds ratio, 2.46; 95% confidence interval, 1.76-3.44), and any type of intimate partner violence during pregnancy (odds ratio, 2.89; 95% confidence interval, 2.03-4.10). Meta-regression analysis showed stronger associations in countries with higher gross domestic product (odds ratio, 1.03; 95% confidence interval, 1.02-1.04) and a higher percentage of health expenditure (odds ratio, 1.27; 95% confidence interval, 1.09-1.46). The proportion of deaths attributable to exposure to intimate partner violence in cohort studies was attributable proportion, 60%; 95% confidence interval, 15-81%. CONCLUSION: Pregnant women who experience intimate partner violence during pregnancy may be about 3 times more likely to suffer perinatal death compared with women who do not experience intimate partner violence. It should be a priority to include intimate partner violence screenings or other detection strategies in pregnancy monitoring or family-planning programs because these could help avoid preventable perinatal deaths.

Prediction of pregnancy complications by second-trimester uterine artery Doppler assessment in monochorionic twins.

PURPOSE: We aimed to investigate whether transabdominal uterine artery (UtA) pulsatility index (PI) differs between monochorionic (MC) diamniotic and dichorionic (DC) twins and is useful to predict pregnancy complications. METHODS: A total of 406 uncomplicated twin pregnancies (94 MC, 312 DC) were examined at 22+0 -24+6 weeks and compared for demographic characteristics, mean UtA PI, presence of notch, development of preeclampsia, fetal growth restriction (FGR), placental abruption, intrauterine fetal death and preterm delivery. Mann-Whitney and Fisher's exact tests were performed for continuous and categorical variables, respectively. Sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio were calculated for mean PI >95th percentile, presence of notch, and presence of either elevated PI or notch. RESULTS: Median mean UtA PI was 0.68 in DC and 0.75 in MC pregnancies (P = .005). Bilateral notches were observed in one MC pregnancy; unilateral notch was seen in 8 DC (2.6%) and 5 MC diamniotic (5.3%) pregnancies. FGR occurred more frequently in DC twin pregnancies, while intrauterine fetal death in MC. Overall, the sensitivity of the parameters tested was low. Pregnancies with both PI above 95th percentile and presence of notch were all associated with complications, particularly FGR. CONCLUSION: MC pregnancies have higher mean UtA PI. UtA screening in twins shows lower performances than in singletons for the detection of complications.
