BACKGROUND: Due to the increasing availability of individual-level information across different electronic datasets, record linkage has become an efficient and important research tool. High quality linkage is essential for producing robust results. The objective of this study was to describe the process of preparing and linking national Brazilian datasets, and to compare the accuracy of different linkage methods for assessing the risk of stillbirth due to dengue in pregnancy. METHODS: We linked mothers and stillbirths in two routinely collected datasets from Brazil for 2009-2010: for dengue in pregnancy, notifications of infectious diseases (SINAN); for stillbirths, mortality (SIM)...

Pakistan has been ranked highest and appears worst in stillbirths' rate according to the recent global estimates. Reasons could be manifold; socio-cultural, health system related country specific, and some of these of course déjà vu, i.e., the biomedical causes. Yet, a fresh stocktaking is necessary to understand the complex phenomenon in a country, awfully affected by this menace. Maternal, neonatal and child health program needs to be informed and geared up toward addressing the actual reasons behind this heavy toll of stillbirths in Pakistan...

AIM: Abnormal placentation is a common pathogenic mechanism of many placenta-mediated complications of late pregnancy, including pre-eclampsia, fetal growth restriction, stillbirth, and placental abruption. During successful placentation, the trophoblast (which is a semi-allograft) is not rejected by decidual immune cells because of maternal immune tolerance, mainly induced by human leukocyte antigen G (HLA-G). Deficient HLA-G expression seems to be associated with the development of complications of pregnancy...

Maternal subclinical hypothyroidism may be associated with adverse pregnancy outcomes, although not consistently across regions. Here, we sought to determine the effect of elevated thyroid-stimulating hormone (TSH) on pregnancy outcomes in Japanese women without known medical complications. TSH was determined by dried blood spots at 8-20 weeks of gestation, and 3.0-10.0 μU/mL of TSH was considered as elevated TSH (eTSH). A retrospective study involving 167 cases of eTSH was conducted. Five hundred and seventy eight of controls with normal TSH and without thyroid antibodies were selected...

Chronic and acute air pollution has been studied in relation to stillbirth with inconsistent findings. We examined stillbirth risk in a retrospective cohort of 223,375 singleton deliveries from 12 clinical sites across the United States. Average criteria air pollutant exposure was calculated using modified Community Multiscale Air Quality models for the day of delivery and each of the seven days prior, whole pregnancy, and first trimester. Poisson regression models using generalized estimating equations estimated the relative risk (RR) of stillbirth and 95% confidence intervals (CI) in relation to an interquartile range increase in pollutant with adjustment for temperature, clinical, and demographic factors...

PROBLEM: Placental dysfunction is present over 50% of cases of stillbirth and fetal growth restriction (FGR). Villitis of unknown etiology (VUE), an inflammatory condition of the placenta characterized by maternal T cell infiltrates in the villous stroma and dysregulation of inflammatory cytokines, is more frequent in FGR and stillbirth. METHOD OF STUDY: A novel in vitro model of placental inflammation was developed to test the hypothesis that inflammatory cells seen in VUE and/or cytokines impair placental function...

Salmonella Typhi can be a significant cause of morbidity and mortality in pregnant females with adverse outcomes. Risk of infections increases manifold during pregnancy due to hormonal changes and immunological phenomena. S. Typhi has the ability to cross placenta (vertical transmission) resulting in miscarriage, stillbirth or premature labour. We report a case of a pregnant female who was admitted to emergency department with fever, missed abortion and hypovolaemic shock. Subsequently, S. Typhi was isolated from her high vaginal swab and blood cultures...

BACKGROUND: In the mid-2000s, neonatal mortality accounted for almost 40% of deaths of children under 5 years worldwide, and constituted 65% of infant deaths in India. The neonatal mortality rate in Andhra Pradesh was 44 per 1,000 live births, and was higher in the rural areas and tribal regions, such as the Nagarkurnool division of Mahabubnagar district (which became Nagarkurnool district in Telangana in 2014). The aim of the CHAMPION trial was to investigate whether a package of interventions comprising community health promotion and provision of health services (including outreach and facility-based care) could lead to a reduction of the order of 25% in neonatal mortality...

<i>An updated neuropathological protocol for the examination of the nervous system in case of unexplained stillbirth has been elaborated and presented in this review. It is focused on the examination of the nervous centers located in the brainstem, which are involved in monitoring the vital functions. Only through a deep analysis of the brainstem it is possible to highlight developmental alterations of these essential centers, and then provide a plausible explanation of the pathogenetic mechanism behind the death...

Fetal sex plays an important role in modifying the course and complications related to pregnancy and may also have an impact on maternal health and well-being both during and after pregnancy. The goal of this article is to review and summarize the findings from published research on physiologic and pathologic changes that may be affected by fetal sex and the effect of these changes on the maternal and obstetrical outcomes. This will help create awareness that fetal sex is not just a random chance event but an interactive process between the mother, the placenta, and the fetus...

Exposure to air pollution may adversely impact placental function through a variety of mechanisms; however, epidemiologic studies have found mixed results. We examined the association between traffic exposure and placental-related obstetric conditions in a retrospective cohort study on Cape Cod, MA, USA. We assessed exposure to traffic using proximity metrics (distance of residence to major roadways and length of major roadways within a buffer around the residence). The outcomes included self-reported ischemic placental disease (the presence of at least one of the following conditions: preeclampsia, placental abruption, small-for-gestational-age), stillbirth, and vaginal bleeding...
