home uterine activity monitoring (huam) has demonstrated to be of great value for preventing preterm labor in recent years. in this research, a low cost monitoring device for non-invasive monitoring of the uterine activity in pregnant women is presented. the new device has been designed based on an inductive colpitz oscillator and vertical displacement of a ferrite core in a coil. the resulting...

preterm birth means the birth before thirty seven week of pregnancy that causes a lot of complications for the baby. variety factors are suggested to be involved in disease. in this study, we decided to evaluate haptoglobin (hp) phenotypes association with clinical features of patients suffered from premature delivery to understand better the possible correlation of genetic and clinical feature...

background: preterm labor (ptl) is the main challenge in prenatal health care, leads to high rate of mortality and  increases cost of health services. to evaluate the preterm delivery (ptd)?related risk factors, we decided to measure nitrite oxide metabolites and cervical length (cl) as the diagnostic and predictive tools for ptd in women and response to tocolytic therapy.materials and methods:...

Uterine contractions occur in runs of 1-3/hr throughout pregnancy from early in the second trimester until full term usually without consequence. Regular uterine contractions are essential in every case of preterm labor (PTL) resulting in preterm delivery at <37 weeks. It has been demonstrated that women are unable to accurately perceive the contractions associated with preterm labor while uter...

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 prev...

background: vaginal bleeding is a common complication during pregnancy, which is observed in about 1/4 of pregnancies and in half of cases can lead to abortion. if vaginal bleeding happens during pregnancy some adverse pregnancy outcomes, including perinatal mortality and morbidity, low birth weight and preterm delivery will be increased. objective:  the aim of this study was to determine the r...

objective : the study evaluated the efficacy and safety of vaginal rogesterone on prevention of recurrent preterm labor. materials and methods: total number of 70 patients with preterm labor treated with intravenous magnesium sulfate in perinatology department of valiasr hospital entered to a randomized clinical trial. treatment group after inhibition of preterm labor with magnesium sulfate rec...

at present, many drugs are used for inhibition of uterine contractions, but the proportions of preterm labors are increasing. although magnesium sulfate is the most commonly prescribed parenteral tocolytic agent, but it’s optimal use has yet to be delineated. in this study a high-dose protocol for magnesium sulfate tocolytic therapy was compared with a low-dose regimen. one hundred patients adm...

background and objective: preterm birth occurs in 8% to 11% of all pregnancies and is responsible for 75% to 80% of all neonatal deaths. cytokines may be involved in the etiology of preterm birth through their stimulation of prostaglandin synthesis. cytokines may be released intocervicovaginal fluid during the breakdown of the chorio-decidual adhesion or from an inflammatory reaction in the sam...
