OBJECTIVES: The purpose of this study was to determined the predictive value of maternal serum alpha-fetoprotein (MSAFP) as a marker for adverse pregnancy outcomes. MATERIAL AND METHODS: This study was carried out at Dr. Zekai Tahir Burak Women's Health Education and Research Hospital between 2009 and 2010. This study included a total of 1,177 pregnant women, including 170 in the study group and 1,007 in the control group. Pregnancy outcomes and characteristics were analyzed with regard to the MSAFP value...

INTRODUCTION: Histologic chorioamnionitis (HC) is a common finding in the placenta from patients with preterm premature rupture of membranes (PPROM). The purpose of this study is to determine if HC differs based on the Group B streptococcus (GBS) status in patients managed expectantly with PPROM <34 weeks gestation. METHODS: A retrospective study was performed of patients admitted with PPROM between 23 0/7 and 33 6/7 weeks from 2003 to 2014 at one institution...

AIM: In this study, we evaluate the associations between fetal urinary production rate (FUPR), measured by ultrasound, and adverse neonatal outcome in women with preterm premature rupture of membranes (PPROM). METHODS: We conducted a prospective pilot cohort of singleton pregnancies complicated by PPROM occurring at gestational week 24 or later managed until spontaneous labor (after 48 h of admission), chorioamnionitis, or induction by protocol at 35 + 0 weeks. FUPR was evaluated by 2D sonography at admission (corrected for gestational age)...

Mid-trimester preterm premature rupture of membranes (PPROM), defined as rupture of fetal membranes prior to 28 weeks of gestation, complicates approximately 0.4%-0.7% of all pregnancies. This condition is associated with a very high neonatal mortality rate as well as an increased risk of long- and short-term severe neonatal morbidity. The causes of the mid-trimester PPROM are multifactorial. Altered membrane morphology including marked swelling and disruption of the collagen network which is seen with PPROM can be triggered by bacterial products or/and pro-inflammatory cytokines...

OBJECTIVE: Factors influencing intraamniotic adiponectin levels and their functional significance remain incompletely elucidated. We prospectively measured adiponectin in amniotic fluid and identified its associations with maternal parameters, mediators in amniotic fluid and pregnancy outcomes. STUDY DESIGN: Mid-trimester amniotic fluid from 571 women was tested for adiponectin, interleukin (IL)-6, IL-8 and α-amylase by enzyme-linked immunosorbant assay (ELISA), after which clinical data were obtained...

Objective To determine reasons for cesarean and medically indicated deliveries in a registry of pregnant women with SLE compared to RA. Methods Pregnant women with SLE or RA were prospectively followed, and pregnancy outcomes were collected, including whether labor was spontaneous or medically indicated and delivery was vaginal or cesarean. Preterm birth was defined as a birth <37 weeks gestation. Differences in reasons for cesarean delivery and indication of delivery between term and preterm births were determined by Fisher's exact test...

OBJECTIVE: To assess the usefulness of cervical parameters measured by transvaginal sonography, ie cervical length and posterior cervical angle, in predicting the admission to delivery interval in women with preterm rupture of membranes. METHODS: This prospective study was conducted in a tertiary care centre in South India. Women with preterm premature rupture of membranes at 28-34 weeks, confirmed clinically, not in labour and presenting within 24 hours to hospital were included...

REVIEW
Tetsuya Kawakita, Helain J Landy
Cesarean delivery (CD) is one of the most common procedures performed in the United States, accounting for 32% of all deliveries. Postpartum surgical site infection (SSI), wound infection and endometritis is a major cause of prolonged hospital stay and poses a burden to the health care system. SSIs complicate a significant number of patients who undergo CD - 2-7% will experience sound infections and 2-16% will develop endometritis. Many risk factors for SSI have been described. These include maternal factors (such as tobacco use; limited prenatal care; obesity; corticosteroid use; nulliparity; twin gestations; and previous CD), intrapartum and operative factors (such as chorioamnionitis; premature rupture of membranes; prolonged rupture of membranes; prolonged labor, particularly prolonged second stage; large incision length; subcutaneous tissue thickness > 3 cm; subcutaneous hematoma; lack of antibiotic prophylaxis; emergency delivery; and excessive blood loss), and obstetrical care on the teaching service of an academic institution...

BACKGROUND: Trichomonas vaginalis (TV) causes the Trichomoniasis Syndrome composed of vaginitis in women, urethritis in men and tube infection in both sexes. This infection is strongly associated with premature rupture of membranes, preterm delivery, low birth weight, promoting HIV sexual transmission and infertility. Prevention of these complications requires accurate early detection and effective treatment of infected individuals. In the resource limited settings, the wet mount microscopy (WMM) is often the only available test for laboratory detection of TV, but its accuracy and that of polymerase chain reaction (PCR) tools in Uganda remain poorly studied...

Egress of the malaria parasite Plasmodium falciparum from its host red blood cell is a rapid, highly regulated event that is essential for maintenance and completion of the parasite life cycle. Egress is protease-dependent and is temporally associated with extensive proteolytic modification of parasite proteins, including a family of papain-like proteins called SERA that are expressed in the parasite parasitophorous vacuole. Previous work has shown that the most abundant SERA, SERA5, plays an important but non-enzymatic role in asexual blood stages...

BACKGROUND: Cervical insufficiency is characterized by premature, progressive dilation and shortening of the cervix during pregnancy. If left unattended, this can lead to the prolapse and rupture of the amniotic membrane, which usually results in midtrimester pregnancy loss or preterm birth. Previous studies have shown that proinflammatory cytokines such as interleukin-1β, interleukin-6, interleukin-8, and tumor necrosis factor alpha are up-regulated in normal parturition but are also associated with preterm birth...

Many countries recommend combined tetanus toxoid, reduced diphtheria toxoid and acellular pertussis immunization (Tdap) during pregnancy to stimulate transplacental transmission of pertussis antibodies to newborns. The immune system can be altered during pregnancy, potentially resulting in differing immunization risks in pregnant women. The safety of widespread Tdap immunization during pregnancy needs to be established. Our objective was to assess whether prenatal Tdap immunization was associated with adverse birth outcomes, and to evaluate the effect of timing of Tdap administration on these outcomes...

BACKGROUND: The incidence of neonatal ear deformities varies widely in the literature, and the incidence of those that correct spontaneously is largely unknown. To address these questions, the authors analyzed the auricles of 1500 newborns from the Pearl River Delta within the first 7 days of life and again at 30 days of age. METHODS: Using a combination of direct measurement and digital image measurement, the authors measured physiognomic ear length, physiognomic ear breadth, morphologic ear length, vertical distance between head and ear, and auriculocephalic angle of the newborns...

Many complications of pregnancy have their pathophysiological roots in the early stages of placentation. Impaired trophoblast invasion and deficient remodelling of the maternal spiral arteries are a common feature. While malperfusion of the placenta may underpin cases of fetal growth restriction and early-onset pre-eclampsia, the mechanistic links to spontaneous miscarriage, pre-term labour and premature rupture of the membranes are less obvious. Here, we speculate that formation of a well-developed cytotrophoblastic shell at the maternal-fetal interface is crucial for pregnancy success...

Chromium exposure from increasing industrial releases has become a threat for pregnant women due to the potential health effects on vulnerable embryos. Previous studies have suggested that maternal chromium exposure is associated with adverse birth outcomes, but no epidemiological research has been conducted to examine the relationship between chromium exposure and premature rupture of membranes (PROM). This study aimed at investigating the association of maternal urinary chromium exposure levels with PROM and was performed with 5408 pregnant women recruited from 2012 to 2014 in the city of Wuhan, China...
