Studies investigating the relationship between maternal passive smoking and the risk of preterm birth have reached inconsistent conclusions. A birth cohort study that included 10,095 nonsmoking women who delivered a singleton live birth was carried out in Lanzhou, China, between 2010 and 2012. Exposure to passive smoking during pregnancy was associated with an increased risk of very preterm bir...
We investigate sex-associated effects of preterm birth on cerebral gray matter (GM) and white matter (WM) volumes. Preterm children (n=65) and 31 healthy, term control children had usable magnetic resonance imaging (MRI) data acquired at 8 years of age. Both GM and WM volumes were significantly reduced in the preterm group compared with controls. However, only males with preterm birth had signi...
BACKGROUND The rate of preterm birth has been increasing worldwide, including in Brazil. This constitutes a significant public health challenge because of the higher levels of morbidity and mortality and long-term health effects associated with preterm birth. This study describes and quantifies factors affecting spontaneous and provider-initiated preterm birth in Brazil. METHODS Data are from...
survival of premature and low birth weight infants: a multicenter, prospective, cohort study in iran
abstractbackground: the survival rate of preterm and low-birth-weight (lbw) infants depends on various factors such as birth weight, gestational age, and quality of care. the present study aimed at evaluating the survival rate of preterm and lbw infants, predictive factors, and the risk of mortality in three training hospitals of mashhad and tabriz cities.methods: this prospective, cohort study...
Globally, each year, an estimated 13 million infants are born before 37 completed weeks of gestation. Complications from these preterm births are the leading cause of neonatal mortality. Preterm birth is directly responsible for an estimated one million neonatal deaths annually and is also an important contributor to child and adult morbidities. Low- and middle-income countries are disproportio...
Introduction: Prematurity remains the main cause of mortality and morbidity in infants and a problem in the care of pregnant women world-wide. This study describes the risk factors for having a live preterm delivery in Bandar Abbas Shariati Hospital. Methods: In this case-control study, we studied 300 neonates who were borned in Shariati hospital in 2011 and divided them into two groups: case g...
Stress increases corticotropin-releasing hormone and may ultimately result in increased uterine contractility. Stress also increases cytokine production, which independently may lead to preterm birth or increase susceptibility to infection, thereby increasing the risk of preterm birth. Finally, stress may change health behaviors that lead to preterm birth. Research findings on the relationship ...
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 reactio...
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...
Introduction. Preterm birth is the leading cause of newborn deaths and the second leading cause of death in children under five years old. Three-quarters of them could be saved with current, cost-effective interventions. The aim of this study was to identify the risk factors of preterm birth in a secondary care hospital in Southern India. Methods. In the case-control study, records of 153 anten...
