ABSTRACT

AIMS/HYPOTHESIS: Pre-existing diabetes is associated with an increased risk of stillbirth, but few studies have excluded the effect of congenital anomalies. This study used data from a long-standing population-based survey of women with pre-existing diabetes to investigate the risks of fetal and infant death and quantify the contribution of glycaemic control. METHODS: All normally formed singleton offspring of women with pre-existing diabetes (1,206 with type 1 diabetes and 342 with type 2 diabetes) in the North of England during 1996-2008 were identified from the Northern Diabetes in Pregnancy Survey. RRs of fetal death (≥20 weeks of gestation) and infant death were estimated by comparison with population data from the Northern Perinatal Morbidity and Mortality Survey. Predictors of fetal and infant death in women with pre-existing diabetes were examined by logistic regression. RESULTS: The prevalence of fetal death in women with diabetes was over four times greater than in those without (RR 4.56 [95% CI 3.42, 6.07], p < 0.0001), and for infant death it was nearly doubled (RR 1.86 [95% CI 1.00, 3.46], p = 0.046). There was no difference in the prevalence of fetal death (p = 0.51) or infant death (p = 0.70) between women with type 1 diabetes and women with type 2 diabetes. There was no evidence that the RR of fetal and infant death had changed over time (p = 0.95). Increasing periconception HbA1c concentration above 49 mmol/mol (6.6%) (adjusted odds ratio [aOR] 1.02 [95% CI 1.00, 1.04], p = 0.01), prepregnancy retinopathy (aOR 2.05 [95% CI 1.04, 4.05], p = 0.04) and lack of prepregnancy folic acid consumption (aOR 2.52 [95% CI 1.12, 5.65], p = 0.03) were all independently associated with increased odds of fetal and infant death. CONCLUSIONS/INTERPRETATION: Pre-existing diabetes is associated with a substantially increased risk of fetal and infant death in normally formed offspring, the effect of which is largely moderated by glycaemic control.

ABSTRACT

Antithrombin (AT) deficiency is a rare hereditary thrombophilia with a mean prevalence of 0.02 % in the general population, associated with a more than ten-fold increased risk of venous thromboembolism (VTE). Within this multicenter retrospective clinical analysis, female patients with inherited AT deficiency were evaluated concerning the type of inheritance and extent of AT deficiency, medical treatment during pregnancy and postpartally, VTE risk as well as maternal and neonatal outcome. Statistical analysis was performed with SPPS for Windows (19.0). A total of 18 pregnancies in 7 patients were evaluated, including 11 healthy newborns ≥37th gestational weeks (gw), one small for gestational age premature infant (25th gw), two late-pregnancy losses (21st and 28th gw) and four early miscarriages. Despite low molecular weight heparin (LMWH) administration, three VTE occurred during pregnancy and one postpartally. Several adverse pregnancy outcomes occurred including fetal and neonatal death, as well as severe maternal neurologic disorders occurred. Patients with substitution of AT during pregnancy in addition to LMWH showed the best maternal and neonatal outcome. Close monitoring with appropriate anticoagulant treatment including surveillance of AT levels might help to optimize maternal and fetal outcome in patients with hereditary AT deficiency.

ABSTRACT

The social determinants of health are the circumstances in which people are born, grow up, live, work, and age and the systems put in place to deal with illness. These circumstances, in turn, are shaped by a wider set of forces: economics, social policies, and politics. Reproductive health indicators and conditions that are germane to obstetricians and gynecologists vary across states and regions in the United States as well as within regions and states. The aim of this article is to illustrate this variation with the use of examples of gynecologic malignancies, sexually transmitted infections, teen birth rates, preterm birth rates, and infant mortality rates. Using the example of infant death, the difficulties in "unpacking" the construct of place will be discussed, and a special emphasis is placed on the interaction of race, place, and disparities in shaping perinatal outcomes. Finally, readily available and easy-to-use online data resources will be provided so that obstetricians and gynecologists will be able to assess geographic variation in health indicators and outcomes in their own localities.

ABSTRACT

OBJECTIVE: The purpose of this study was to determine the prospective risk of intrauterine fetal death (IUFD) at ≥34 weeks' gestation for monochorionic and dichorionic twins receiving intensive antenatal fetal surveillance. The secondary objective was to calculate the incidence of prematurity-related neonatal morbidity/mortality rates that have been stratified by gestational week and chorionicity. STUDY DESIGN: A retrospective cohort study of all twins at ≥34 weeks' gestation who were delivered at the Medical University of South Carolina (1987-2010) was performed. Twins were cared for in a longstanding Twin Clinic with standardized treatment and surveillance protocols and supervised by a consistent Maternal-Fetal Medicine specialist. Gestational age-specific fetal/neonatal mortality rates and composite neonatal morbidity rates were compared by chorionicity. A generalized linear mixed model was used to identify variables that were associated with increased composite neonatal morbidity. RESULTS: Among 768 twin gestations (601 dichorionic and 167 monochorionic), only 1 dichorionic IUFD occurred. The prospective risk of IUFD at ≥34 weeks' gestation was 0.17% for dichorionic twins and 0% for monochorionic twins. Composite neonatal morbidity decreased with each gestational week (P < .0001). Morbidity was increased by white race, gestational diabetes mellitus, and elective indication for delivery. The nadir of composite neonatal morbidity occurred at 36/0-36/6 weeks' gestation for monochorionic twins and 37/0-37/6 weeks' gestation for dichorionic twins. CONCLUSION: Our data do not support concern for an increased risk of stillbirth in uncomplicated intensively monitored monochorionic twins at ≥34 weeks' gestation. However, our data do show significantly increased rates of neonatal morbidity in late preterm monochorionic twins that cannot be justified by a corresponding reduction in the risk of stillbirth. We believe that our data support delivery of uncomplicated monochorionic twins at 37 weeks' gestation.

ABSTRACT

OBJECTIVE: Obesity is a known risk factor for stillbirth. However, this relationship has not been characterized fully. We attempted to further examine this relationship with a focus on delivery near and at term. STUDY DESIGN: We designed a retrospective cohort study of singleton nonanomalous live births and stillbirths in the states of Washington and Texas to examine the associations of maternal prepregnancy body mass index (BMI) and risk of stillbirth. Confounder-adjusted hazard ratio of stillbirth in relation to BMI was estimated through Cox proportional hazards regression model. The hazard ratio was used to estimate the population-attributable risk. We also estimated the fetuses who were at risk for stillbirth based on gestational age. RESULTS: Among 2,868,482 singleton births, the overall stillbirth risk was 3.1 per 1000 births (n = 9030). Compared with normal-weight women, the hazard ratio for stillbirth was 1.36 for overweight women, 1.71 for class I obese women, 2.00 for class II obese women, 2.48 for class III obese women, and 3.16 for women with a BMI of ≥50 kg/m(2). The fetuses who are at risk for stillbirth increased after 39 weeks' gestation for each obesity class; however, the risk increased more rapidly with increasing BMI. Women with a BMI of ≥50 kg/m(2) were at 5.7 times greater risk than normal weight women at 39 weeks' gestation and 13.6 times greater at 41 weeks' gestation. Obesity was associated with nearly 25% of stillbirth that occurred between 37 and 42 weeks' gestation. CONCLUSION: There is a pronounced increase in the risk of stillbirth with increasing BMI; the association is strongest at early- and late-term gestation periods. Extreme maternal obesity is a significant risk factor for stillbirth.

ABSTRACT

OBJECTIVE: To study whether a routine with a routine ultrasound examination (routine scan) at 41 gestational weeks as compared with ultrasound on clinical indication (indicated scan), lowered the risk of severe adverse fetal outcome in post-term period. DESIGN: A retrospective cohort study. SETTING: Karolinska University Hospital, Stockholm, Sweden. POPULATION: Eight years of deliveries, 2002-2009. METHOD: One of the two delivery units at Karolinska University Hospital used a routine scan at 41 week of gestation and the other unit used an indicated scan. Severe adverse fetal outcome were defined: severe asphyxia, death or cerebral damage. The study was analysed using logistic regression with adjustment for potential confounders. MAIN OUTCOME MEASURES: Differences in post-term severe adverse fetal outcome. RESULTS: No increased risk of post-term severe adverse fetal outcome was seen at the unit using a routine scan; conversely, a 48% significantly increased risk was seen at the unit using an indicated scan (OR 0.89, 95% confidence interval, CI, 0.5-1.5 and OR 1.48, 95% CI 1.06-2.1, respectively). Comparing post-term periods, there was no significantly increased risk at the unit using indicated scans (OR 1.6, 95% CI 0.9-3.0). There was a 60% increased prevalence of small-for-gestational age (SGA) newborns in the post-term period at the unit using indicated scans (OR 1.6, 95% CI 1.1-2.4), but no differences in operative delivery. CONCLUSION: A policy to use routine scans at 41 weeks of gestation seems to normalise an increased post-term risk of severe adverse fetal outcome, possible due to increased awareness of SGA and/or oligohydramniosis.

ABSTRACT

BACKGROUND: Adolescent pregnancies are a growing public health problem in Cameroon. We sought to study the outcome of such pregnancies, in order to inform public health action. METHODS: A cross-sectional analysis of 5997 deliveries which compared the outcome of deliveries in adolescent (10-19 years old) pregnant women registered at the Yaoundé Central Hospital between 2008 and 2010 to that of their non-adolescent adult (≥ 20 years old) counterparts. Variables used for comparison included socio-demographic and obstetric characteristics of parturients, referral status, and maternal and fetal outcomes. Predictors of maternal and of perinatal mortality were determined through binomial logistic modeling. RESULTS: Adolescent deliveries represented 9.3% (560) of all pregnancies registered. Adolescent pregnancies had significantly higher rates of both gestational duration extremes: preterm as well as post-term deliveries (29.3% versus 24.5%, p = 0.041 OR 1.28 95% CI 1.01-1.62 and 4.9 versus 2.4%, p = 0.014 OR 2.11 95% CI 1.46-3.87 respectively). Both groups did not differ significantly with respect to mean blood loss, rates of cesarean or instrumental deliveries. Adolescent deliveries however required significantly twice as many episiotomies (OR 2.15 95% CI 1.59-2.90). The likelihood of perineal tears in the adolescent group was significantly higher than that in the adult group on assuming episiotomies done would have been tears if they had not been carried out (OR 1.45 95% CI 1.16-1.82). Adolescent parturients had a higher likelihood of apparent fetal death at birth as well as perinatal fetal death after resuscitation efforts (AOR 1.75 95% CI 1.25-2.47 and AOR 1.69 95% CI 1.17-2.45 respectively).Comparisons of pregnancy outcomes between early (10-14 years), middle (15-17 years) and late adolescence (18-19 years) found no significant differences. Predictors of maternal death included having been referred, having had ≥5 deliveries and preterm deliveries. These were also predictors of perinatal death, as well as being a single mother, primiparous, and multiple gestations. CONCLUSIONS: Adolescent pregnancies in Cameroon compared to those in adults are associated with poorer outcomes. There is need for adolescent-specific services to prevent teenage pregnancies as well as interventions to prevent and manage the above mentioned predictors of in-facility maternal and perinatal mortality.

ABSTRACT

BACKGROUND: The social disparity in perinatal mortality may vary by the age of the offspring. We studied offspring mortality from pregnancy week 16 until 1 year after birth by maternal educational level. METHODS: We included all births in Norwegian women during the years 1999-2004 (n = 297 663). The Medical Birth Registry of Norway was linked to the Norwegian Education Registry to obtain individual information on maternal education at the time of delivery. Information on infant mortality was obtained by linkage to the Norwegian Central Person Registry. RESULTS: In pregnancy weeks 37 through 43 and in the first week after birth, there was little difference in offspring mortality by maternal education. Before pregnancy week 37, the excess offspring mortality associated with compulsory school only was >60% using university/college education as the reference. During the 2nd through 12th month after birth, the excess mortality was 132% in offspring of mothers with compulsory school only. CONCLUSION: The social disparity in offspring mortality was lowest in pregnancies at term and in the first week after birth. In this period, all women living in Norway and their infants use the public health care service extensively. Our results may suggest that health care that is equally available to all citizens, reduces social disparities in mortality.

ABSTRACT

BACKGROUND: The use of post-mortem imaging, including skeletal radiography, CT and MRI, is increasing, providing a minimally invasive alternative to conventional autopsy techniques. The development of clinical guidelines and national standards is being encouraged, particularly for cross-sectional techniques. OBJECTIVE: To outline the current practice of post-mortem imaging amongst members of the European Society of Paediatric Radiology (ESPR). MATERIALS AND METHODS: We e-mailed an online questionnaire of current post-mortem service provisions to members of the ESPR in January 2013. The survey included direct questions about what services were offered, the population imaged, current techniques used, imaging protocols, reporting experience and intended future involvement. RESULTS: Seventy-one percent (47/66) of centres from which surveys were returned reported performing some form of post-mortem imaging in children, of which 81 % perform radiographs, 51% CT and 38% MRI. Eighty-seven percent of the imaging is performed within the radiology or imaging departments, usually by radiographers (75%), and 89% is reported by radiologists, of which 64% is reported by paediatric radiologists. Overall, 72% of positive respondents have a standardised protocol for radiographs, but only 32% have such a protocol for CT and 27% for MRI. Sixty-one percent of respondents wrote that this is an important area that needs to be developed. CONCLUSION: Overall, the majority of centres provide some post-mortem imaging service, most of which is performed within an imaging department and reported by a paediatric radiologist. However, the populations imaged as well as the details of the services offered are highly variable among institutions and lack standardisation. We have identified people who would be interested in taking this work forwards.

ABSTRACT

BACKGROUND: Umbilical cord prolapse is an obstetric complication associated with high perinatal morbidity and mortality. A few interventions may improve fetal outcome. In developed countries these have advanced to giving intrauterine fetal resuscitation. Conditions in low resource settings do not allow for some of these advanced techniques. Putting the mother in knee chest position and immediate delivery may be the only options possible.We set out to determine the incidence of fetal demise and associated factors following umbilical cord prolapsed (UCP) in Mulago Hospital, Uganda. METHODS: In a retrospective study conducted in Mulago hospital, Uganda, file records of mothers who delivered between 1st January 2000 to 31st December 2009 and had pregnancies complicated by umbilical cord prolapse with live fetus were selected. We collected information on referral status, cord position, cervical dilatation, fetal heart state at the time of diagnosis of UCP, diagnosis to delivery interval, use of knee chest position, mode of delivery, birth weight and fetal outcome.We computed incidence of fetal demise following UCP and determined factors associated with fetal demise in pregnancies complicated by UCP. RESULTS: Of 438 cases with prolapsed cord, 101(23%) lost their babies within 24 hours after birth or were delivered dead. This gave annual cumulative incidence of fetal death following UCP of 23/1000 live UCP cases delivered /year.The major factors associated with fetal outcome in pregnancies complicated by UCP included; diagnosis to delivery interval <30 min, RR 0.79 (CI 0.74-0.85), mode of delivery, RR 1.14 (CI 1.02-1.28), knee chest position, RR 0.81 (CI 0.70-0.95). CONCLUSIONS: The annual cumulative incidence of fetal death in our study was 23/1000 live UCP cases delivery per year for the period of 10 years studied. Cesarean section reduced perinatal mortality by a factor of 2. Diagnosis to delivery interval <30 minutes and putting mother in knee chest position were protective against fetal death.

ABSTRACT

AIMS: To describe the outcome of pregnancy in patients with structural or ischaemic heart disease. METHODS AND RESULTS: In 2007, the European Registry on Pregnancy and Heart disease was initiated by the European Society of Cardiology. Consecutive patients with valvular heart disease, congenital heart disease, ischaemic heart disease (IHD), or cardiomyopathy (CMP) presenting with pregnancy were enrolled. Data for the normal population were derived from the literature. Sixty hospitals in 28 countries enrolled 1321 pregnant women between 2007 and 2011. Median maternal age was 30 years (range 16-53). Most patients were in NYHA class I (72%). Congenital heart disease (66%) was most prevalent, followed by valvular heart disease 25%, CMP 7%, and IHD in 2%. Maternal death occurred in 1%, compared with 0.007% in the normal population. Highest maternal mortality was found in patients with CMP. During pregnancy, 338 patients (26%) were hospitalized, 133 for heart failure. Caesarean section was performed in 41%. Foetal mortality occurred in 1.7% and neonatal mortality in 0.6%, both higher than in the normal population. Median duration of pregnancy was 38 weeks (range 24-42) and median birth weight 3010 g (range 300-4850). In centres of developing countries, maternal and foetal mortality was higher than in centres of developed countries (3.9 vs. 0.6%, P < 0.001 and 6.5 vs. 0.9% P < 0.001) CONCLUSION: The vast majority of patients can go safely through pregnancy and delivery as long as adequate pre-pregnancy evaluation and specialized high-quality care during pregnancy and delivery are available. Pregnancy outcomes were markedly worse in patients with CMP and in developing countries.

ABSTRACT

IMPORTANCE: Evidence suggests that maternal obesity increases the risk of fetal death, stillbirth, and infant death; however, the optimal body mass index (BMI) for prevention is not known. OBJECTIVE: To conduct a systematic review and meta-analysis of cohort studies of maternal BMI and risk of fetal death, stillbirth, and infant death. DATA SOURCES: The PubMed and Embase databases were searched from inception to January 23, 2014. STUDY SELECTION: Cohort studies reporting adjusted relative risk (RR) estimates for fetal death, stillbirth, or infant death by at least 3 categories of maternal BMI were included. DATA EXTRACTION: Data were extracted by 1 reviewer and checked by the remaining reviewers for accuracy. Summary RRs were estimated using a random-effects model. MAIN OUTCOMES AND MEASURES: Fetal death, stillbirth, and neonatal, perinatal, and infant death. RESULTS: Thirty eight studies (44 publications) with more than 10,147 fetal deaths, more than 16,274 stillbirths, more than 4311 perinatal deaths, 11,294 neonatal deaths, and 4983 infant deaths were included. The summary RR per 5-unit increase in maternal BMI for fetal death was 1.21 (95% CI, 1.09-1.35; I2 = 77.6%; n = 7 studies); for stillbirth, 1.24 (95% CI, 1.18-1.30; I2 = 80%; n = 18 studies); for perinatal death, 1.16 (95% CI, 1.00-1.35; I2 = 93.7%; n = 11 studies); for neonatal death, 1.15 (95% CI, 1.07-1.23; I2 = 78.5%; n = 12 studies); and for infant death, 1.18 (95% CI, 1.09-1.28; I2 = 79%; n = 4 studies). The test for nonlinearity was significant in all analyses but was most pronounced for fetal death. For women with a BMI of 20 (reference standard for all outcomes), 25, and 30, absolute risks per 10,000 pregnancies for fetal death were 76, 82 (95% CI, 76-88), and 102 (95% CI, 93-112); for stillbirth, 40, 48 (95% CI, 46-51), and 59 (95% CI, 55-63); for perinatal death, 66, 73 (95% CI, 67-81), and 86 (95% CI, 76-98); for neonatal death, 20, 21 (95% CI, 19-23), and 24 (95% CI, 22-27); and for infant death, 33, 37 (95% CI, 34-39), and 43 (95% CI, 40-47), respectively. CONCLUSIONS AND RELEVANCE: Even modest increases in maternal BMI were associated with increased risk of fetal death, stillbirth, and neonatal, perinatal, and infant death. Weight management guidelines for women who plan pregnancies should take these findings into consideration to reduce the burden of fetal death, stillbirth, and infant death.

ABSTRACT

IMPORTANCE: Unencapsulated Haemophilus influenzae frequently causes noninvasive upper respiratory tract infections in children but can also cause invasive disease, especially in older adults. A number of studies have reported an increased incidence in neonates and suggested that pregnant women may have an increased susceptibility to invasive unencapsulated H. influenzae disease. OBJECTIVE: To describe the epidemiology, clinical characteristics, and outcomes of invasive H. influenzae disease in women of reproductive age during a 4-year period. DESIGN, SETTING, AND PARTICIPANTS: Public Health England conducts enhanced national surveillance of invasive H. influenzae disease in England and Wales. Clinical questionnaires were sent prospectively to general practitioners caring for all women aged 15 to 44 years with laboratory-confirmed invasive H. influenzae disease during 2009-2012, encompassing 45,215,800 woman-years of follow-up. The final outcome was assessed in June 2013. EXPOSURES: Invasive H. influenzae disease confirmed by positive culture from a normally sterile site. MAIN OUTCOMES AND MEASURES: The primary outcome was H. influenzae infection and the secondary outcomes were pregnancy-related outcomes. RESULTS: In total, 171 women had laboratory-confirmed invasive H. influenzae infection, which included 144 (84.2%; 95% CI, 77.9%-89.3%) with unencapsulated, 11 (6.4%; 95% CI, 3.3%-11.2%) with serotype b, and 16 (9.4%; 95% CI, 5.4%-14.7%) with other encapsulated serotypes. Questionnaire response rate was 100%. Overall, 75 of 171 women (43.9%; 95% CI, 36.3%-51.6%) were pregnant at the time of infection, most of whom were previously healthy and presented with unencapsulated H. influenzae bacteremia. The incidence rate of invasive unencapsulated H. influenzae disease was 17.2 (95% CI, 12.2-24.1; P < .001) times greater among pregnant women (2.98/100,000 woman-years) compared with nonpregnant women (0.17/100,000 woman-years). Unencapsulated H. influenzae infection during the first 24 weeks of pregnancy was associated with fetal loss (44/47; 93.6% [95% CI, 82.5%-98.7%]) and extremely premature birth (3/47; 6.4% [95% CI, 1.3%-17.5%]). Unencapsulated H. influenzae infection during the second half of pregnancy was associated with premature birth in 8 of 28 cases (28.6%; 95% CI, 13.2%-48.7%) and stillbirth in 2 of 28 cases (7.1%; 95% CI, 0.9%-23.5%). The incidence rate ratio for pregnancy loss was 2.91 (95% CI, 2.13-3.88) for all serotypes of H. influenzae and 2.90 (95% CI, 2.11-3.89) for unencapsulated H. influenzae compared with the background rate for pregnant women. CONCLUSIONS AND RELEVANCE: Among women in England and Wales, pregnancy was associated with a greater risk of invasive H. influenzae infection. These infections were associated with poor pregnancy outcomes.

ABSTRACT

The occurrence rate of gastrointestinal hemorrhage (GIH) of nonvaricosal genesis in pregnant women was analyzed. The risk of complications occurrence in the pregnancy course while performing local endoscopic hemostasis and prophylaxis of the hemorrhage recurrence occurrence was established. Application of elaborated treatment method for GIH of nonvaricosic genesis in pregnant women have promoted reduction of the severe complications rate in the pregnancy course, applying elimination of the vasoconstrictor and uterotonic effects of adrenalin, reduction of esophagogastroduodenoscopy duration. While application of this procedure in pregnant women of a main group operative cessation of GIH was not applied. In a comparison group a hemostasis, using operative way, was done in 2 (13.3%) women patients with subsequent occurrence of preeclampsy, what resulted in antenathal fetal death.

ABSTRACT

BACKGROUND: The World Health Organization initiative to eliminate mother-to-child transmission of syphilis aims for ≥ 90% of pregnant women to be tested for syphilis and ≥ 90% to receive treatment by 2015. We calculated global and regional estimates of syphilis in pregnancy and associated adverse outcomes for 2008, as well as antenatal care (ANC) coverage for women with syphilis. METHODS AND FINDINGS: Estimates were based upon a health service delivery model. National syphilis seropositivity data from 97 of 193 countries and ANC coverage from 147 countries were obtained from World Health Organization databases. Proportions of adverse outcomes and effectiveness of screening and treatment were from published literature. Regional estimates of ANC syphilis testing and treatment were examined through sensitivity analysis. In 2008, approximately 1.36 million (range: 1.16 to 1.56 million) pregnant women globally were estimated to have probable active syphilis; of these, 80% had attended ANC. Globally, 520,905 (best case: 425,847; worst case: 615,963) adverse outcomes were estimated to be caused by maternal syphilis, including approximately 212,327 (174,938; 249,716) stillbirths (>28 wk) or early fetal deaths (22 to 28 wk), 91,764 (76,141; 107,397) neonatal deaths, 65,267 (56,929; 73,605) preterm or low birth weight infants, and 151,547 (117,848; 185,245) infected newborns. Approximately 66% of adverse outcomes occurred in ANC attendees who were not tested or were not treated for syphilis. In 2008, based on the middle case scenario, clinical services likely averted 26% of all adverse outcomes. Limitations include missing syphilis seropositivity data for many countries in Europe, the Mediterranean, and North America, and use of estimates for the proportion of syphilis that was "probable active," and for testing and treatment coverage. CONCLUSIONS: Syphilis continues to affect large numbers of pregnant women, causing substantial perinatal morbidity and mortality that could be prevented by early testing and treatment. In this analysis, most adverse outcomes occurred among women who attended ANC but were not tested or treated for syphilis, highlighting the need to improve the quality of ANC as well as ANC coverage. In addition, improved ANC data on syphilis testing coverage, positivity, and treatment are needed. Please see later in the article for the Editors' Summary.

ABSTRACT

BACKGROUND: Systemic lupus erythematosus (SLE) is associated with adverse pregnancy outcomes overall. OBJECTIVE: To examine the outcomes for women with SLE in a pregnancy subsequent to a first birth with an adverse outcome. METHODS: A population-based cohort study was carried out of 794 577 deliveries to 532 612 women giving birth in New South Wales, Australia from 2001 to 2009. Data were obtained from longitudinally linked birth records and hospital records. RESULTS: 675 women had a diagnosis of SLE in the study period (prevalence 127 per 100 000 childbearing women). Of 177 women who had a first nulliparous birth and subsequent pregnancy, 10 (5.6%) had a perinatal death in the first pregnancy, and of these women, 9 (90%) had a baby discharged home alive in the second pregnancy. Of the 167 women whose first-birth infants survived, second pregnancy outcomes included: 18 (11%) admission for spontaneous abortion, 1 perinatal death (0.6%) and 148 (89%) infants discharged home. Two women had a thromboembolic event in their first pregnancy but had no thromboembolic event in the second. Two women had thromboembolic events in second pregnancies only. CONCLUSION: Women with SLE are at high risk of adverse pregnancy outcomes. However, those who have a perinatal death in their first pregnancy can expect a live birth for a subsequent pregnancy.

ABSTRACT

OBJECTIVE: To determine the role of viral infections in causing fetal and infant death. STUDY DESIGN: We assessed a well-validated population database of fetal (≥20 weeks gestation) and infant death for infective deaths and deaths from viruses over a 21-year period (1988-2008). We analyzed by specific viral cause, timing (late fetal loss [20-23 weeks], stillbirth [≥24 weeks], neonatal death [0-27 days], and post-neonatal infant death [28-364 days]) and across time. RESULTS: Of the 989 total infective deaths, 108 were attributable to viral causes (6.5% of late fetal losses, 14.5% of stillbirths, 6.5% of neonatal deaths, and 19.4% of postneonatal infant deaths). Global loss (combined fetal and infant losses per 100,000 registerable births) was 139.6 (95% CI, 130.9-148.3) for any infective cause and 15.2 (95% CI, 12.3-18.1) for viral infections. More than one-third (37%) of viral-attributed deaths were before live birth, from parvovirus (63%) or cytomegalovirus (33%). Parvovirus accounted for 26% (28 of 108) of all viral deaths. Cytomegalovirus was associated with a global loss rate of 3.1 (95% CI, 1.8-4.4) and an infant mortality rate of 1.3 (95% CI, 0.4-2.1) per 100,000 live births; 91% of cases were congenital infections. Herpes simplex virus caused death only after live births (infant mortality rate, 1.4; 95% CI, 0.5-2.3). No changes in rates were seen over time. CONCLUSION: We have identified a substantial contribution of viral infections to global fetal and infant losses. More than one-third of these losses occurred before live births. Considering our methodology, our estimates represent the minimum contribution of viral illness. Strategies to reduce this burden are needed.

ABSTRACT

OBJECTIVE: To perform a systematic review and meta-analysis of reported estimates of adverse pregnancy outcomes among untreated women with syphilis and women without syphilis. METHODS: PubMed, EMBASE and Cochrane Libraries were searched for literature assessing adverse pregnancy outcomes among untreated women with seroreactivity for Treponema pallidum infection and non-seroreactive women. Adverse pregnancy outcomes were fetal loss or stillbirth, neonatal death, prematurity or low birth weight, clinical evidence of syphilis and infant death. Random-effects meta-analyses were used to calculate pooled estimates of adverse pregnancy outcomes and, where appropriate, heterogeneity was explored in group-specific analyses. FINDINGS: Of the 3258 citations identified, only six, all case-control studies, were included in the analysis. Pooled estimates showed that among untreated pregnant women with syphilis, fetal loss and stillbirth were 21% more frequent, neonatal deaths were 9.3% more frequent and prematurity or low birth weight were 5.8% more frequent than among women without syphilis. Of the infants of mothers with untreated syphilis, 15% had clinical evidence of congenital syphilis. The single study that estimated infant death showed a 10% higher frequency among infants of mothers with syphilis. Substantial heterogeneity was found across studies in the estimates of all adverse outcomes for both women with syphilis (66.5% [95% confidence interval, CI: 58.0-74.1]; I(2) = 91.8%; P < 0.001) and women without syphilis (14.3% [95% CI: 11.8-17.2]; I(2) = 95.9%; P < 0.001). CONCLUSION: Untreated maternal syphilis is associated with adverse pregnancy outcomes. These findings can inform policy decisions on resource allocation for the detection of syphilis and its timely treatment in pregnant women.

ABSTRACT

OBJECTIVE: The objective of this study was to review the medical literature that has reported the risk for intrauterine fetal death (IUFD) in pregnancies with gastroschisis. STUDY DESIGN: We systematically searched the literature to identify all published studies of IUFD and gastroschisis through June 2011 that were archived in MEDLINE, PubMed, or referenced in published manuscripts. The MESH terms gastroschisis or abdominal wall defect were used. RESULTS: Fifty-four articles were included in the metaanalysis. There were 3276 pregnancies in the study and a pooled prevalence of IUFD of 4.48 per 100. Those articles that included gestational age of IUFD had a pooled prevalence of IUFD of 1.28 per 100 births at ≥36 weeks' gestation. The prevalence did not appear to increase at >35 weeks' gestation. CONCLUSION: The overall incidence of IUFD in gastroschisis is much lower than previously reported. The largest risk of IUFD occurs before routine and elective early delivery would be acceptable. Risk for IUFD should not be the primary indication for routine elective preterm delivery in pregnancies that are affected by gastroschisis.

ABSTRACT

OBJECTIVE: To compare the risk of fetal death (FD) between 34 and 41 weeks' gestational age (GA) with the neonatal mortality rate to examine the best GA for delivery. STUDY DESIGN: Linked birth and infant death data for the US from the National Center for Health Statistics analyzed nonanomalous singleton pregnancies between 2003 and 2005. Pregnancies were classified as high risk or low risk based on preexisting maternal complications. Outcomes of 8,785,132 live births and 12,777 FDs between 34 and 42 completed weeks' gestation were examined. The risk of FD was determined using the following equation: The FD risk of those remaining undelivered was compared with the neonatal death rate for each week of gestation. RESULTS: Between 34 and 40 weeks' gestation, the FD risk of those remaining undelivered for all pregnancies declined and then increased at term. For high risk pregnancies, the FD risk of those remaining undelivered is substantially higher than for low risk pregnancies. The number of FDs that can be avoided by delivery exceeds the neonatal death rate between 37 and 38 weeks' gestation in low risk pregnancies and at 36 weeks' gestation in high risk pregnancies. CONCLUSION: These findings suggest that delivery at 39 weeks' gestation in both high and low risk pregnancies would result in an increased number of perinatal deaths. Decisions regarding the "optimal time for delivery" should include the risk of remaining undelivered.
