Background: Recent studies have demonstrated the high prevalence of vitamin D deficiency in the general population. Pregnancy and preterm delivery are known as risk factors for vitamin D deficiency. Consequently, vitamin D level in women with preterm deliveries might vary from those with term pregnancies. In this study, we aimed to compare vitamin D level in term and preterm infant–mother pairs...

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 ...

BACKGROUND There is an association between periodontal diseases and preterm delivery. AIM To assess the relationship between periodontal diseases, ascending bacterial infection and placental pathology with preterm delivery. PATIENTS AND METHODS A periodontal examination and collection of amniotic fluid and subgingival plaque samples were performed in women with preterm labor with intact mem...

OBJECTIVE The aim of this study was to evaluate the influence on preterm delivery of changes in putative genetic and environmental risk factors between two consecutive births. Low social status is a suspected risk indicator of preterm delivery, but the impact of social mobility has not been studied before. PARTICIPANTS The study uses national cohorts in which women act as their own controls. ...

Preterm delivery is the leading cause of neonatal mortality and morbidity. The rate of preterm births has been estimated to be about 15 million, which accounts for 11.1% of all live births worldwide. The purpose of this study was to evaluate the cervico-vaginal (CVF) cytokine IL-6 and fetal fibronectin (fFN) status as predictors of preterm delivery in patients with symptoms of preterm labor. Pa...

BACKGROUND Protease inhibitor (PI)-based highly active antiretroviral therapy (HAART) use in pregnancy has been associated with preterm deliveries in some observational studies. METHODS HIV-infected, HAART-naive pregnant women with CD4+ counts ≥200 cells/mm(3) were randomized between 26 and 34 weeks gestation to lopinavir/ritonavir/zidovudine/lamivudine (PI group) or abacavir/zidovudine/lamiv...

The purpose of this study was to evaluate the relationship between the levels of βhCG cervicovaginal secretions and preterm delivery. A cross-sectional analysis was used and cerevicovaginal secretion specimens were obtained from women in their 24th-36th weeks (every 6 days) of pregnancy who presented the pregnancy clinic with preterm labor manifestations. Frozen samples (at -20°C) were assayed ...

Background: The objective was to find the role of maternal serum Creactive protein and Chlamydia trachomatis IgG antibodies as predictors of preterm delivery. Methods: This prospective study was conducted in UISEMH, Department of Obstetrics and Gynecology, GSVM Medical College, Kanpur from September 2011 to September 2013. The present study comprised of a total of 100 cases, out of which 50 wer...
