INTRODUCTION: To compare tocolysis with magnesium sulfate versus atosiban regarding the occurrence of short-term preterm labor and maternal side effects during and after open fetal myelomeningocele (MMC) repair. MATERIAL AND METHODS: A prospective nonrandomized cohort study was performed including 30 fetal MMC cases. The first 15 cases (group 1) received magnesium sulfate according to the MOMS protocol. In the following 15 cases (group 2), magnesium sulfate was substituted by atosiban...

OBJECTIVE: To evaluate maternal serum C-reactive protein (CRP) concentrations in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) in relation to the presence of microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI). METHODS: Two hundred and eighty-seven women with singleton pregnancies complicated by PPROM between 2014 and 2016 were included in this study. Maternal blood and amniotic fluid samples were collected at the time of admission...

Preterm prelabor rupture of the membranes (pPROM) remains a significant obstetric problem that affects 3-4% of all pregnancies and precedes 40-50% of all preterm births. pPROM arises from complex, multifaceted pathways. In this review, we summarize some old concepts and introduce some novel theories related to pPROM pathophysiology. Specifically, we introduce the concept that pPROM is a disease of the fetal membranes where inflammation-oxidative stress axis plays a major role in producing pathways that can lead to membrane weakening through a variety of processes...

OBJECTIVE: The aim of this study was to investigate whether a previously reported vaginal fluid point-of-care interleukin (IL)-6 cut-off value of 2,500 pg/mL can be used for the identification intra-amniotic inflammation in women with preterm prelabor rupture of membranes (PPROM) between 34 and 37 weeks. MATERIAL AND METHODS: A prospective cohort study was conducted in women with singleton gestation complicated by PPROM between 34 + 0 and 36 + 6 weeks. Vaginal fluid was successfully obtained in 118 women from the posterior vaginal fornix via aspiration using a sterile urine sample tube with a suction tip...

OBJECTIVE: To evaluate the importance of assessment of fetal cardiac output (CO) for the prediction of complications of pregnancy. METHODS: We evaluated 65 fetuses and all of them had a fetal cardiac scan at 20 to 24 weeks of pregnancy. To measure CO, diameters (d) of the left right ventricle outflow tract were measured just above the valves. Each left CO (LCO) and right CO (RCO) was derived using the following equation: CO = velocity time integral × π × d(2)/4 × heart rate...

OBJECTIVE: The objective of this study is to determine child health, development and educational outcomes for infants born following preterm prelabor rupture of the membrane (PPROM). STUDY DESIGN: Population-based record linkage cohort study using data from NSW, Australia, 2001 to 2014. RESULTS: Of 121 822 births at 20 to 37 weeks, 18 799 (15%) followed PPROM, 56 406 (46%) followed spontaneous labor and 46 617 (38%) were planned. Compared with infants of a similar gestational age born following spontaneous labor or planned delivery, exposure to PPROM did not increase the risk of childhood mortality, childhood hospitalization, developmentally vulnerable at school entry, low reading or numeracy scores...

OBJECTIVES: Preterm premature rupture of membranes (PPROM) is a major contributor to overall preterm birth (PTB) rates. A short interpregnancy interval (IPI) is a well-known risk factor for PTB. It is unknown if a short IPI specifically affects the risk of developing PPROM in a subsequent pregnancy. We sought to determine the association between IPI and the risk of PPROM in a subsequent pregnancy. METHODS: A retrospective cohort study using the Missouri birth certificate database of singleton births from 2003-2013 was conducted...

Inflammation at the maternal-fetal interface has been shown to be involved in the pathogenesis of preterm birth. Interleukin 27 (IL-27), a heterodimeric cytokine, is known to mediate an inflammatory response in some pregnancy complications. In this study, we aimed to determine whether IL-27 could induce an inflammatory reaction at the maternal-fetal interface that would mediate the onset of preterm birth. We found elevated expression of IL-27 in human peripheral serum and elevated expression of its specific receptor (wsx-1) on fetal membranes in cases of preterm birth...

The aim of the study was to demonstrate that preterm birth (PTB) is associated with altered C19MC microRNA expression profile in placental tissues. Gene expression of 15 placental specific microRNAs (miR‑512‑5p, miR‑515‑5p, miR‑516‑5p, miR‑517‑5p, miR‑518b, miR‑518f‑5p, miR‑519a, miR‑519d, miR‑519e‑5p, miR‑520a‑5p, miR‑520h, miR‑524‑5p, miR‑525‑5p, miR‑526a and miR‑526b‑5p) was compared between groups: 34 spontaneous PTB, 108 preterm prelabor rupture of membranes (PPROM) and 20 term in labor pregnancies...

OBJECTIVE: Periodontal disease is frequently suggested as a possible causal factor for preterm delivery. The link between periodontal disease and preterm delivery is a possible translocation of periopathogenic bacteria to the placenta and amniotic fluid as well as a systemic response to this chronic inflammatory disease. However, there is a lack of information on whether there is an association between clinical periodontal status in women with preterm prelabor rupture of membranes (PPROM) and the presence of microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation (IAI)...

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)...

INTRODUCTION: Several studies report a decrease of fetal heart rate (FHR) short-term variation (STV) after corticosteroids for improvement of fetal maturity and advice not to deliver a fetus for low STV within 2-3days after corticosteroids. However, literature is not unanimous in this respect. This study intends to asses STV longitudinally after corticosteroid administration. MATERIAL AND METHODS: A retrospective cohort study in a tertiary perinatal centre from 2009 to 2015 included all women who had been treated with corticosteroids at gestational age of 26-34 weeks, had a computerized cardiotocography (cCTG) before and after medication and did not deliver within 48h...

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 assess the usefulness of cervical parameters measured by transvaginal sonography, that is, 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.
