BACKGROUND Preterm birth is a major cause of neonatal mortality and morbidity. As preventive strategies are largely ineffective, threatened preterm labor is a frequent problem that affects approximately 10 % of pregnancies. In recent years, risk assessment in these women has incorporated cervical length measurement and fetal fibronectin testing, and this has improved the capacity to identify wo...
OBJECTIVE Pentraxin 3 (PTX3) is a soluble pattern recognition receptor (PRR) that has an important role in immunoregulation and vascular integrity. The aim of this study was to determine if PTX3 is present in amniotic fluid (AF) and whether its concentration changes with gestational age (GA), in the presence of preterm or term labor, and in cases of intra-amniotic infection/inflammation (IAI) a...
BACKGROUND To investigate the risk factors for vaginal infections and antimicrobial susceptibilities of vaginal microorganisms among women who experienced preterm birth (PTB), we compared the prevalence of vaginal microorganisms between women who experienced preterm labor (PTL) without preterm delivery and spontaneous PTB. METHODS Vaginal swab specimens from 126 pregnant women who experienced...
Ulrich C, Quilici DR, Schlauch KA, Buxton IL. The human uterine smooth muscle S-nitrosoproteome fingerprint in pregnancy, labor, and preterm labor. Am J Physiol Cell Physiol 305: C803–C816, 2013. First published August 15, 2013; doi:10.1152/ajpcell.00198.2013.—Molecular mechanisms involved in uterine quiescence during gestation and those responsible for induction of labor at term are incomplete...
OBJECTIVE Multiple studies suggest that bacterial vaginosis (BV) causes preterm labor; yet its routine treatment remains controversial. In order to help to elucidate this controversy, we performed a thorough review of studies with levels of evidence ranging from I to II-II. METHODS We searched for all of the studies from the years 1994 to 2001 via Medline's database, including MD Consult and ...
Premature delivery occurs in 12% of all births, accounts for nearly half of neonatal morbidity and is increasing in frequency. Current therapeutic approaches to preterm delivery are ineffective and present serious risks to both the mother and fetus. Although there are multiple factors that contribute to the etiology of preterm birth, the single most common cause is infection. Recently, using cD...
BACKGROUND Matrix metalloproteinases (MMPs) are involved in remodeling of the extracellular matrix (ECM) during pregnancy and parturition. Aberrant ECM degradation by MMPs or an imbalance between MMPs and their tissue inhibitors (TIMPs) have been implicated in the pathogenesis of preterm labor, however few studies have investigated MMPs or TIMPs in maternal serum. Therefore, the purpose of this...
background: morbidity and mortality of preterm babies are important issues in perinatal medicine. in developed countries, preterm delivery is the cause of about 70% of mortality and 75% of morbidity in the neonatal period, respectively. objective: the aim of this study was to determine the risk factors for preterm labor and the outcomes, in terms of perinatal mortality and morbidity at the time...
Purpose: The proper function of amnion is necessary for a normal pregnancy and delivery to occur. Understanding the change of amnion between term and preterm labor leads to a better method of diagnosis and prevention for preterm labor. Lysyl oxidase (LOX) catalyzes a series of reactions about the formation of cross-linking of collagen fibrils. Human amniotic tissue, containing a large amount of...
Introduction: Preterm delivery is one of the essential midwifery problems, which causes a large proportion of infant mortality even in advanced societies. Despite advances in pregnancy care, the frequency of preterm delivery has not decreased. This study aimed to determine the relationship between serum calcium, phosphorus, and magnesium level with preterm labor in pregnant women. Methods: In ...
