RESUMO

RATIONALE: Posterior reversible encephalopathy syndrome (PRES), a rare neurologic disorder, manifests as headache, altered mental status, seizures, visual disturbances, and other focal neurologic signs with typically reversible clinical symptoms and image changes. Although the underlying mechanism remains unknown, a current theory indicates cerebral autoregulation failure as the primary cause. We report a case of PRES with stroke in an adult with intrauterine fetal death (IUFD). PATIENT CONCERNS: A 35-year-old Asian woman with twin pregnancy underwent cesarean section at 32 weeks of gestation because of IUFD. She presented with focal seizures and visual field defect 2 days after undergoing cesarean section. Her blood pressure and kidney, liver, and coagulation functions were normal without proteinuria. DIAGNOSIS: PRES was diagnosed based on a series of brain magnetic resonance imaging findings. Ischemic infarction in the right frontal lobe eventually developed to encephalomalacia. INTERVENTIONS: The patient received levetiracetam and valproate for seizure management. OUTCOMES: Five days after the onset, seizures were under control. All neurologic deficits completely improved after 21 days of admission. LESSONS: PRES can occur in women with IUFD without preeclampsia or eclampsia symptoms. Although most cases result in vasogenic edema of the brain and exhibit good prognosis, PRES can cause cytotoxic edema and permanently damage the brain.

RESUMO

Este artigo se baseia em um estudo de série temporal sobre os óbitos fetais por malformações congênitas no estado do Maranhão relativo ao período de 2006 a 2016. Foram construídos indicadores epidemiológicos para estimar o risco de morte fetal e sua tendência ao longo da série estudada. Os dados são provenientes do Departamento de Informática do SUS e sua análise realizada por modelos de regressão linear. Foram registrados 17.843 óbitos fetais no período abordado pelo estudo, 528 dos quais decorrentes de malformações congênitas (2,96%). Observou-se uma tendência significativa de aumento do coeficiente de mortalidade fetal geral, correspondente a 6,99% (ß1=0,17; p=0,004) e do específico por malformações congênitas, equivalente a 5,13% (ß1=0,01; p=0,04). Os resultados deste estudo corroboram a tendência histórica dos serviços de saúde negligenciarem os óbitos fetais. É importante destacar que parte destes óbitos são preveníveis e potencialmente evitáveis. Desse modo, a implementação dos comitês de investigação de óbitos fetais e infantis e a sua vigilância adequada poderiam melhorar a assistência prestada tanto no pré-natal quanto no parto.


This article bases on a time series study about fetal deaths due to congenital malformations in the state of Maranhão, Brazil, occurred from 2006 to 2016. Epidemiological indicators were constructed to estimate the risk of fetal death and its trend throughout the series studied. The data were obtained in the Department of Informatics of SUS and analyzed by linear regression models. There were 17,843 fetal deaths during the analysed period, from which 528 were a direct result of congenital malformations (2.96%). A significant tendency towards an increase in the coefficient of general fetal mortality corresponding to 6.99% (ß1=0.17; p=0.004) and in the coefficient of specific fetal mortality due to congenital malformations equivalent to 5.13% (ß1=0.01; p=0.04) were observed. The end results of this study corroborate the historical trend toward negligence in Brazilian health centres with regard to fetal deaths. It is important to remark that some of these deaths can be presumed and potentially preventable. Thus, the implementation of the fetal and infant death investigation committees and their adequate surveillance could improve care during prenatal and delivery.

RESUMO

RATIONALE: The umbilical cord is the way to exchange gas, supply nutrients, excrete metabolized. Thrombosis of the umbilical cord leads to fetal hypoxia, which jeopardizes fetal health and can cause fetal death. Umbilical vessel thrombosis, which is rarely reported, is difficult to detect prenatally. PATIENT CONCERNS: Both pregnant women had an unremarkable pregnancy course until a routine ultrasound scan in the third trimester showed a single umbilical artery. However, one umbilical vein and 2 umbilical arteries were seen during an ultrasound examination at 32 weeks. Case 2 had a better pregnancy outcome because of the timely discovery of this complication. DIAGNOSIS: Both cases were diagnosed as umbilical artery thrombosis. INTERVENTIONS: The first patient received no interventions until they reported decreased fetal movements and gradually disappear. The second patient underwent an emergency cesarean section. OUTCOMES: In Case 1, an emergency ultrasound examination showed intrauterine fetal death, and the patient vaginally delivered a stillborn child weighing 3300 g in a day. In Case 2, a female neonate weighing 2860 g was delivered by cesarean section, and exhibited Apgar scores of 10 and 10 at 1 and 5 minutes. CONCLUSION: In the late-term abortions, obstetricians should be vigilant if ultrasound imaging shows suspected umbilical vascular thrombosis or shows 1 umbilical artery when there had previously been 2. The fetus should be closely monitored and interventions implemented as early as possible to improve the prenatal detection rate of umbilical vessel thrombosis and avoid adverse pregnancy outcomes.

RESUMO

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.

RESUMO

Importance: Listeriosis is a rare foodborne condition that can cause serious health consequences in neonates and pregnant women. Listeria monocytogenes can be vertically transmitted to the fetus, resulting in adverse maternal, fetal, and neonatal outcomes. In this review, we summarize what is currently known about listeriosis in pregnancy and review the current management and treatment recommendations. Objective: To summarize the clinical and relevant evidence available regarding listeriosis in pregnancy and educate providers on common clinical symptoms, sequelae, and appropriate treatment guidelines. Evidence Acquisition: A PubMed review was conducted using search terms "pregnancy" OR "Listeria" OR "Maternal Listeriosis," and "Neonatal Listeriosis." The search included review articles, original research articles, and guidelines on diagnosis and management of listeriosis in pregnancy. The search was limited to the English language and publications between 1988 and July 2018. Conclusions: Listeriosis in pregnancy can result in severe adverse maternal, fetal, and neonatal outcomes including miscarriage, preterm labor, fetal death, and neonatal meningitis and sepsis. Early treatment has been shown to improve fetal and neonatal outcomes; therefore, prevention with education and early diagnosis prompting treatment will improve overall outcomes. Relevance: The incidence of listeriosis is expected to rise in the coming years due to changes in the US population, with increasing numbers of older Americans and Hispanic individuals, both of whom are at higher risk. Pregnant women contract listeriosis at a rate that is 16- to 18-fold greater than the general population. Given the expected increased rise in incidence and increased susceptibility of pregnant women, understanding the common clinical symptoms, maternal and fetal sequelae, and appropriate treatment guidelines is essential.

RESUMO

Data based on forensic autopsy in neonates and infants in China are rare in the literature. The purpose of this study is to evaluate the characteristics of fetal, neonatal, and infant death and to determine the main cause of death among them.A retrospective analysis of fetal and infant forensic autopsies referred to the Tongji Forensic Medical Center (TFMC) in Hubei, central China, during a 16-year period between January 1999 and December 2014, was performed.In this period, there were 1111 males and 543 females; the total male-to-female ratio (MFR) was 2.05:1. There were 173 fetal and infant autopsies conducted, comprised of 43 fetal, 84 neonatal (<28 days) and 46 infant (4 weeks to 1 year) cases. The annual case number ranged from 5 in 2004 to 18 in 2014 (annual mean of 10.8). MFR was 1.75:1. About 94% of these deaths (163/173) resulted from natural causes, 6 cases (3.5%) were accidental deaths, and 4 (2.3%) resulted from homicide (4 abandoned babies). Among fetuses, the most common causes of death were placental and umbilical cord pathologies (28%, 12/43), followed by intrapartum asphyxia resulting from amniotic fluid aspiration (AFA) or meconium aspiration syndrome (MAS) (18.6%, 8/43), congenital malformation (14%, 6/43), and intrapartum infection (9.3%, 4/43). A majority of neonatal deaths (66.7%, 56/84) died within 24 hours of birth. The main causes of neonatal death were asphyxia resulting from AFA, MAS, or hyaline membrane disease, and congenital malformation. The main causes of infant (1-12 months) death were infectious diseases, including pneumonia, meningitis, and viral brainstem encephalitis.This study was the 1st retrospective analysis of autopsies of fetal, neonatal, and infant death in TFMC and central China. We delineate the common causes of early demise among cases referred for autopsy, and report a male preponderance in this population. Our data observed that placental and/or umbilical cord pathology, asphyxia due to AFA, and/or MAS, and pneumonia were the leading causes of fetal, neonatal, and infant death, respectively. And it can inform clinical practitioners about the underlying causes of some of the most distressing cases in their practices.

RESUMO

Placenta percreta is the abnormal invasion of the placenta through the myometrium and serosa of the uterus. It is the most invasive of the placenta accreta spectrum followed by placenta increta. This paper presents a case of a maternal and fetal death in the second trimester due to rupture of the uterus at the site of placenta percreta in a C-section scar. Postmortem MRI showed a large hemoperitoneum and thinning of the anterolateral uterine wall. Internal examination revealed two liters of blood in the abdomen and rupture of the anterolateral uterine wall at the site of placenta percreta in a previous C-section scar. Placenta percreta is a rare complication of pregnancy, however, it is becoming more common with the increasing rate of C-section, the most common and significant risk factor.

RESUMO

INTRODUCTION: Placental abruption (PA) is a serious complication of pregnancy, associated with significant perinatal complications, including intrauterine fetal demise (IUFD). Continuous electronic fetal monitoring (EFM) has been widely applied in China in recent decades. Exploration of potentially PA-specific patterns of EFM contributes to early detection of PA occurrence. PATIENT CONCERNS AND DIAGNOSIS: A 33-year-old woman (gravida 3, para 1) was referred to our hospital at 33 weeks gestation due to non-reassuring fetal heart rate (FHR) pattern, and suffered sudden onset of severe PA and subsequent intrauterine fetal demise. INTERVENTIONS: We analyzed the characteristics of her non-stress tests (NSTs) 1 day and 10 min before the detection of PA, aiming to explore potentially PA-specific patterns of EFM and provide reference for early detection of asymptomatic PA occurrence in obstetric practice. OUTCOMES: Unfavored characteristics of FHR patterns before PA onset are analyzed. CONCLUSION: For those who sense decreased fetal movements (DFMs), a NST and a biophysical profile (BPP) are recommended for exclusion of potential adverse maternal and fetal complications.

RESUMO

BACKGROUND: Under certain situations, women with twin pregnancies may be counseled to undergo invasive prenatal diagnostic testing. Chorionic villus sampling and amniocentesis are the two generally performed invasive prenatal diagnostic tests. Studies comparing procedure-related fetal loss between first-trimester chorionic villus sampling and second-trimester amniocentesis in twin pregnancies are limited. This study aimed to evaluate the procedure-related fetal loss and the obstetrical outcomes of these two procedures, chorionic villus sampling and amniocentesis in twin pregnancies. METHODS: The data from dichorionic-diamniotic twin pregnancies on which first-trimester chorionic villus sampling (n = 54) or second-trimester amniocentesis (n = 170) was performed between December 2006 and January 2017 in a single center were retrospectively analyzed. The procedure-related fetal loss was classified as loss of one or all fetuses within 4 weeks of procedure, and overall fetal loss was classified as loss of one or all fetuses during the gestation. The groups were compared with respect to the procedure-related and obstetrical outcomes. RESULTS: The difference in proportion of procedure-related fetal loss rate (1.9% for chorionic villus sampling vs. 1.8% for amniocentesis; P = 1.000) and the overall fetal loss rate (7.4% for chorionic villus sampling vs. 4.7% for amniocentesis; P = 0.489) between the two groups was not significant. The mean gestational ages at delivery were not statistically significant. CONCLUSION: Both the overall fetal loss rate and the procedure-related fetal loss rate of chorionic villus sampling and amniocentesis in dichorionic twin pregnancies had no statistical significance. Both procedures can be safely used individually.

RESUMO

BACKGROUND: Intrauterine fetal death is a traumatic event. Stillbirth rate is an important indicator to assess the quality of antenatal care. The objective of the study was to identify the risk factors related to intrauterine fetal death in patients admitted with intrauterine fetal death. METHODS: It was a descriptive study conducted in the department of Obstetrics and Gynaecology at B. P. Koirala Institute of Health Sciences from January to December 2014. Patients admitted with singleton pregnancy with intrauterine fetal death after 28 weeks gestation were included. RESULTS: There were 11,006 obstetric admissions. Of them, 152 women had intrauterine fetal death. There were 128(84.2%) women between 20-35 years of age. Out of 152, 81(53.3%) women were preterm and 39(2.1%) women were postterm. Primigravida were 77(50.7%) followed by 35(23%) of second gravida. Hypertension was the commonest identified risk factor in 30(26.78%) women. Out of 152 women, 49(32.2%) had not received formal education. Ten (6.6%) women had a past history of fetal death. Four (2.6%) women had medical disorder before pregnancy. One hundred and twenty five (82.2%) women had vaginal delivery, 21(13.8%) had caesarean section and 6(3.9%) had laparotomy for rupture uterus. The commonest indication for caesarean section was placenta previa for 7(33.33%) women. Four (2.6%) women had diabetes. Ninety five (62.5%) were male and 57(37.5%) were female babies. Five (3.3%) babies had malformations. CONCLUSIONS: Hypertension in pregnancy was found to be the most common identified risk factor for intrauterine fetal death.

RESUMO

The objective of this study was identify the association between delays in the care provided to pregnant women and the fetal death outcome, in a tertiary reference maternity hospital in the Northeastern Brazil. A case-control study, with 72 cases of fetal death and 144 controls (live births) in women admitted to the Obstetrics Service of the Assis Chateaubriand Teaching Maternity Hospital, in Fortaleza, Ceará. Controls were matched (2:1) by the approximate gestational age of the case. The groups were compared using the three delays model of obstetric care. The Pearson's Chi-square test and the Fisher's exact test were used to compare the groups. P <0.05 was considered statistically significant. The Group with fetal death had a smaller number of prenatal consultations (> 6 consultations: 27.8% in cases, 40.3% in controls, p = 0.003), less risk classification of pregnancy (41.7% vs 55.9%, p = 0.048), less guidance about the health facility for delivery (44.5% vs 64%, p = 0.009), lower frequency of cesarean sections (25.4% vs 65.7%) and higher frequency of hemorrhagic syndromes (33.3% vs 19.4%, p = 0.024) and syphilis (15.3% vs 4.2%, p = 0·004). Variables that persisted significantly associated with fetal death in the logistic regression were: Refusal of assistance (OR = 4.07, IC 95%: 1.08-15.3), Absence or inadequacy of prenatal care (OR = 2.69, IC 95%: 1.07-6.75), Delay in diagnosis (OR = 10.3, IC 95%: 2.58-41.4) and Inadequate patient conduct (OR = 4.88; IC 95%: 1.43-16.6). Despite of having a higher frequency of obstetric complications, gestations with fetal death are more prone to delays in obstetric care.

RESUMO

Equine piroplasmosis is a tick-borne disease caused by the protozoan parasites Babesia caballi and Theileria equi. We report a case of abortion in association with transplacental Theileria equi infection in a mare from the State of Espírito Santo, southeast Brazil. An apparently healthy mare aborted at the tenth month of gestation. At necropsy, the subcutaneous tissue, skeletal muscles, and visible mucosae of the aborted fetus were pale, and there was moderate hydrothorax and marked splenomegaly. Microscopic findings included splenic lymphoid hyperplasia and nephrosis. Merozoite-infected erythrocytes were found within blood vessels of all organs examined and were most numerous in the brain. DNA extracted from the spleen, liver, kidney, and thymus was used as a template for PCR. Generic primers were employed for the detection of piroplasm 18S ribosomal gene. All samples were positive for piroplasm DNA by PCR. Amplicons were purified and then sequenced. Sequencing analysis of these amplicons revealed 98% identity to T. equi sequences. Based on our findings, we suggest that abortion in this case resulted from transplacental Theileria infection.(AU)


A piroplasmose equina é transmitida por carrapatos, sendo causada pelos protozoários Babesia caballi e Theileria equi. O objetivo deste trabalho foi relatar um caso de aborto equino associado à piroplasmose fetal. Uma égua gestante, aparentemente saudável, abortou no 10º mês de gestação. Na necropsia do feto, foi observada palidez de subcutâneo, da musculatura esquelética e das mucosas visíveis, moderado hidrotórax e acentuada esplenomegalia. Histologicamente, havia hiperplasia linfoide esplênica e nefrose. Muitos merozoítos foram observados em eritrócitos nos vasos sanguíneos de todos os órgãos examinados, com maior intensidade no encéfalo. Amostras de DNA do baço, fígado, rim e timo foram utilizadas para PCR com primers genéricos para detecção de sequências do gene 18S ribossomal de piroplasmas, com resultado positivo para todas as amostras. Em seguida, os amplicons das amostras de baço foram purificados, sequenciados e, após análise, mostraram 98% de identidade com a sequência de T. equi. Portanto, as alterações microscópicas, os resultados de PCR e sequenciamento confirmam aborto associado à T. equi por transmissão transplacentária.(AU)

RESUMO

OBJECTIVES: To evaluate the association of fresh and frozen embryo transfer with the development of ischemic placental disease (IPD), hypothesizing that differences in implantation environment affect placentation and thus pregnancy outcomes. DESIGN: We performed a secondary analysis of a retrospective cohort study of deliveries linked to IVF cycles. SETTING: Tertiary hospital and infertility treatment center. PATIENT(S): We included all women who underwent an autologous IVF cycle and had a live-born infant or an intrauterine fetal demise (IUFD). We excluded women less than 18 years of age. INTERVENTION(S): We compared pregnancies resulting from frozen embryo transfer (frozen) cycles with those resulting from fresh embryo transfer (fresh) cycles. MAIN OUTCOME MEASURE(S): The primary outcome was a composite outcome of IPD or IUFD due to placental insufficiency. Ischemic placental disease included pre-eclampsia, placental abruption, and small for gestational age (SGA). We calculated risk ratios (RRs) and 95% confidence intervals (CIs). RESULT(S): Compared with fresh cycles, frozen cycles had a lower risk of IPD or IUFD from placental insufficiency (RR 0.75, 95% CI 0.59-0.97). Frozen cycles also conferred a lower risk of SGA than fresh cycles (RR 0.58, 95% CI 0.41-0.81). Risks of pre-eclampsia (RR 1.3, 95% CI 0.84-1.9) and abruption (RR 1.2, 95% CI 0.56-2.4) were similar. CONCLUSION(S): There was a lower risk of IPD among frozen cycles compared with fresh cycles. This association was largely driven by lower risk of SGA among frozen cycles.

RESUMO

Electronic Health Records (EHR) contain extensive information on various health outcomes and risk factors, and therefore have been broadly used in healthcare research. Integrating EHR data from multiple clinical sites can accelerate knowledge discovery and risk prediction by providing a larger sample size in a more general population which potentially reduces clinical bias and improves estimation and prediction accuracy. To overcome the barrier of patient-level data sharing, distributed algorithms are developed to conduct statistical analyses across multiple sites through sharing only aggregated information. The current distributed algorithm often requires iterative information evaluation and transferring across sites, which can potentially lead to a high communication cost in practical settings. In this study, we propose a privacy-preserving and communication-efficient distributed algorithm for logistic regression without requiring iterative communications across sites. Our simulation study showed our algorithm reached comparative accuracy comparing to the oracle estimator where data are pooled together. We applied our algorithm to an EHR data from the University of Pennsylvania health system to evaluate the risks of fetal loss due to various medication exposures.

RESUMO

Acute appendicitis is the most frequent surgical disease complicating pregnancy. Accurate diagnosis is difficult due to atypical and misleading clinical manifestations. Surgeons frequently do not know about advantages and disadvantages of different diagnostic methods applied during pregnancy. Treatment of acute appendicitis in pregnant women remains the real challenge for surgeons. There are enough researches indicating on benefits and risks of both open and laparoscopic operations. The main risk is due to fetal loss after laparoscopic procedure. Safety of diagnostic techniques and laparoscopic procedures, surgical tactics and independent risk factors of pregnancy loss are touched in the article.

RESUMO

OBJECTIVE: To compare induction of labour at 41 weeks with expectant management until 42 weeks in low risk women. DESIGN: Open label, randomised controlled non-inferiority trial. SETTING: 123 primary care midwifery practices and 45 hospitals (secondary care) in the Netherlands, 2012-16. PARTICIPANTS: 1801 low risk women with an uncomplicated singleton pregnancy: randomised to induction (n=900) or to expectant management until 42 weeks (n=901). INTERVENTIONS: Induction at 41 weeks or expectant management until 42 weeks with induction if necessary. PRIMARY OUTCOME MEASURES: Primary outcome was a composite of perinatal mortality and neonatal morbidity (Apgar score <7 at five minutes, arterial pH <7.05, meconium aspiration syndrome, plexus brachialis injury, intracranial haemorrhage, and admission to a neonatal intensive care unit (NICU). Secondary outcomes included maternal outcomes and mode of delivery. The null hypothesis that expectant management is inferior to induction was tested with a non-inferiority margin of 2%. RESULTS: Median gestational age at delivery was 41 weeks+0 days (interquartile range 41 weeks+0 days-41 weeks+1 day) for the induction group and 41 weeks+2 days (41 weeks+0 days-41 weeks+5 days) for the expectant management group. The primary outcome was analysed for both the intention-to-treat population and the per protocol population. In the induction group, 15/900 (1.7%) women had an adverse perinatal outcome versus 28/901 (3.1%) in the expectant management group (absolute risk difference -1.4%, 95% confidence interval -2.9% to 0.0%, P=0.22 for non-inferiority). 11 (1.2%) infants in the induction group and 23 (2.6%) in the expectant management group had an Apgar score <7 at five minutes (relative risk (RR) 0.48, 95% CI 0.23 to 0.98). No infants in the induction group and three (0.3%) in the expectant management group had an Apgar score <4 at five minutes. One fetal death (0.1%) occurred in the induction group and two (0.2%) in the expectant management group. No neonatal deaths occurred. 3 (0.3%) neonates in the induction group versus 8 (0.9%) in the expectant management group were admitted to an NICU (RR 0.38, 95% CI 0.10 to 1.41). No significant difference was found in composite adverse maternal outcomes (induction n=122 (13.6%) v expectant management n=102 (11.3%)) or in caesarean section rate (both groups n=97 (10.8%)). CONCLUSIONS: This study could not show non-inferiority of expectant management compared with induction of labour in women with uncomplicated pregnancies at 41 weeks; instead a significant difference of 1.4% was found for risk of adverse perinatal outcomes in favour of induction, although the chances of a good perinatal outcome were high with both strategies and the incidence of perinatal mortality, Apgar score <4 at five minutes, and NICU admission low. TRIAL REGISTRATION: Netherlands Trial Register NTR3431.

RESUMO

Autopsy reports of 78 stillbirths and early infant deaths (up to age 8 weeks) were reviewed to investigate the prevalence of extrahepatic nonreticuloendothelial siderosis (EHNRS) in the context of neonatal liver failure. Of these, 10 liveborns (12.8%), M:F 3:2, with mean gestational age 37.6 weeks (range: 35-39) and mean age at the time of demise 19.1 days (range: 7-42), showed significant liver injury: infection (n = 7, viral > fungal), congenital malformations (n = 2), and ischemia (n = 1). None had maternal history of gestational alloimmune liver disease (GALD) or previous fetal/neonatal death due to liver failure. Seven of 10 cases (70%) showed EHNRS: pancreas (n = 6), kidneys (n = 4), thyroid and adrenal glands (n = 3), and bronchial glands and heart (n = 2). Iron deposition was most frequent in the pancreas (60%), most diffuse in the kidneys, and seen in at least 2 organs, with pancreas and kidney being the most frequent combination. Hepatic C5b-9 expression was variable (1+ to 4+) except 1 case (100% necrosis). The duration of illness and the mean age at the time of demise tended to be higher in those with EHNRS. In summary, hepatic and EHNRS, with or without C5b-9 expression, are not specific for GALD. Other causes of liver failure should be investigated as clinically and pathologically appropriate.

RESUMO

AIMS: To evaluate the interaction effects of gestational diabetes (GDM) with obesity on perinatal outcomes. METHODS: A population-based cohort study in Sweden excluding women without pre-gestational diabetes with a singleton birth between 1998 and 2012. Logistic regression was performed to evaluate the potential independent associations of GDM and BMI with adverse perinatal outcomes as well as their interactions. Main outcome measures were malformations, stillbirths, perinatal mortality, low Apgar score, fetal distress, prematurity and Erb's palsy. RESULTS: Some 1,294,006 women were included, with a GDM prevalence of 1% (n = 14,833). The rate of overweight/obesity was 67.7% in the GDM-group and 36.1% in the non-GDM-group. No significant interaction existed. Offspring of women with GDM had significantly increased risk of malformations, adjusted odds ratio (aOR) 1.16 (95% confidence intervals 1.06-1.26), prematurity, aOR 1.86 (1.76-1. 98), low Apgar score, aOR 1.36 (1.10-1.70), fetal distress, aOR 1.09 (1.02-1.16) and Erb's palsy aOR 2.26 (1.79-2.86). No risk for stillbirth or perinatal mortality was seen. Offspring of overweight (BMI 25-29.9 kg/m2 ), obese (BMI 30-34.9 kg/m2 ) and severely obese women (BMI ≥ 35.0 kg/m2 ) had significantly increased risks of all outcomes including stillbirth 1.51 (1.40-1.62) to 2.85 (2.52-3.22) and perinatal mortality 1.49 (1.40-1.59) to 2.83 (2.54-3.15). CONCLUSIONS: There is no interaction effect between GDM and BMI for the studied outcomes. Higher BMI and GDM are major independent risk factors for most serious adverse perinatal outcomes. More effective pre-pregnancy and antenatal interventions are required to prevent serious adverse pregnancy outcomes among women with either GDM or high BMI.

RESUMO

Background: The purpose of this study was to determine prognostic factors that can affect the fetal survival immediate after fetoscopic laser ablation. Methods: The study population consisted of consecutive twin pregnant women who underwent fetoscopic laser ablation with the diagnosis of twin to twin transfusion syndrome (TTTS) from 2011 to 2018 in Seoul National University Hospital. Fetal survival immediate after procedure was defined as survival to 48 hours after procedure and neonatal survival was defined as survival to 28 days of life. Clinical characteristics and ultrasound findings were compared according to the fetal survival immediate after procedure. Results: A total of 57 pregnant women with TTTS were included, and the overall fetal survival immediate after procedure was 71.1% (81/114) after fetoscopic laser ablation. Fetuses who survived immediate after procedure had higher gestational age at procedure and lower frequency of abnormal Doppler studies than those did not survive. However, the frequency of hydrops was not different between cases with fetal survival and those with fetal death. The earlier gestational age at procedure and the presence of abnormal Doppler studies were significant risk factors for fetal death even after adjustment. Conclusion: Based on this data, the fetal survival immediate after procedure (fetoscopic laser treatment) in TTTS can be affected by the gestational age at procedure and the presence of abnormal Doppler studies.
