background: group b streptococcus is regarded as a potential factor for adverse outcomes of pregnancy such as preterm birth. objective: to study the association of maternal vaginal colonization with group b streptococcus (gbs) and preterm labor. materials and methods: from april 2005 to may 2006, vaginal culture for gbs were conducted in 101 laboring women with a gestational age of 24-37 weeks ...

Preterm labor is defined as the presence of regular uterine contractions with progressive cervical changes before 37 completed weeks of pregnancy. Spontaneous preterm labor accounts for 40% to 50% of all preterm births [1]. An estimated 13 million babies (−10% of all births) are born preterm each year worldwide, and approximately 1 million of all newborn deaths are due to preterm birth [2]. At ...

OBJECTIVE The complement system plays a central role in the first line of defense against invading pathogens, and its activation involves the release of potent pro-inflammatory mediators such as anaphylatoxins C3a, C4a and C5a. The aim of this study was to determine whether differences existed in maternal plasma anaphylatoxin concentrations between patients with term and preterm parturition. ...

INTRODUCTION Preterm labor is the main cause of infants' death, and the main reason for undesirable consequences of pregnancy which still occur in some births, despite all of the interventions in this regard. The aim of this study was to evaluate every preterm birth and determine its maternal risk factors in Hormozgan province in 2013. METHODS This case-control study was conducted in 2013 on ...

BACKGROUND Localized inflammation and increased expression of TLR4 receptors within the uterus has been implicated in the pathogenesis of preterm labor. It remains unclear whether intrauterine inflammatory responses activate the maternal peripheral circulatory system. Therefore we determined whether increased TLR4 expression is present in the peripheral maternal white blood cells of women with ...

BACKGROUND Preterm birth is still the leading cause of neonatal morbidity and mortality. The level of corticotropin-releasing hormone (CRH) is known to be significantly elevated in the maternal plasma at preterm birth. Although, CRH, CRH-binding protein (CRH-BP), CRH-receptor 1 (CRH-R1) and CRH-R2 have been identified both at mRNA and protein level in human placenta, deciduas, fetal membranes, ...

OBJECTIVE To study the prevalence of bacterial vaginosis (BV) in pregnant women with preterm labor in Siriraj hospital. MATERIAL AND METHOD A cross-sectional study of 158 pregnant women with suspected preterm labor was performed between January and July 2005. The subjects enrolled in the present study were between 28+0 and 36+6 menstrual weeks. BV blue test was performed on the vaginal fluid ...

and mortality worldwide. Spontaneous preterm labor, with intact or rupture of the chorioamniotic membranes, is responsible for two-thirds of all preterm births. The cost of preterm birth to society is estimated to be approximately $20 billion per year in the United States alone.1 Until recently, preterm labor was considered to result from extemporaneous activation of the components ofthe common...

Introduction: Considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hCG) and that hCG can inhibit myometrial contractions on vitro, made me study treating effects of hCG on preterm labor. This clinical trial study was carried out to compare the effect of hCG, and magnesium sulfate (mgso4) on pre...
