OBJECTIVE This study was undertaken to determine whether progestational agents, initiated in the second trimester of pregnancy, reduce the risk of delivery less than 37 weeks, among women at increased risk of spontaneous preterm birth. STUDY DESIGN Medline, pre-Medline, EMBASE, and Cochrane Central Register of Controlled Trials were searched. Randomized controlled trials with less than 20% lo...

OBJECTIVE The objective of this study was to explore the association between occupational factors and pregnancy outcomes in a prospective cohort of Irish pregnant women. DESIGN This study has a prospective design. POPULATION The Lifeways cohort included 1124 pregnant women, 676 of whom delivered a single baby and were working at their first prenatal care visit when they filled in a self-adm...

Disruptions to brain development associated with shortened gestation place individuals at risk for the development of behavioral and psychological dysfunction throughout the lifespan. The purpose of the present study was to determine if the benefit for brain development conferred by increased gestational length exists on a continuum across the gestational age spectrum among healthy children wit...

OBJECTIVE To examine the potential value of maternal serum level of α-fetoprotein (AFP) in the first trimester of pregnancy in the prediction of spontaneous early preterm delivery. METHODS Maternal serum concentration of AFP at 11-13 weeks' gestation was measured in a case-control study of singleton pregnancies delivering phenotypically normal neonates, including 33 cases with spontaneous del...

When a woman becomes pregnant her body undergoes tremendous changes hormonally and anatomically. Our survey revealed very little literature on biomechanics of gait in gravidas and lack of consensus among scientists in pregnancy-related mechanisms of body adaptation. That is why the authors felt encouraged to determine the effect of pregnancy on the biomechanical pattern of walking. To investiga...

OBJECTIVES To establish the relationship of cervical length at 23 weeks of gestation to the risk of spontaneous delivery before 33 weeks and to determine the possible additional risk if funneling is present. METHODS During a 36-month period, 6819 women with singleton pregnancies underwent transvaginal sonographic cervical assessment at 22-24 weeks as a screening test for preterm delivery. The...

the main objective of this study was to estimate the genetic parameters for multi-trait evaluation of birth weight (bw), gestation length (gl) and calving difficulty (cd) in first-parity iranian holstein dairy cattle. the data included 29,950 calving records collected during 1995 to 2014 by the animal breeding and improvement center of iran. a threshold-linear sire-maternal grandsire model was ...

Background: The transmembrane protein gp130 plays a central role in cytokine action as a signal transducing receptor subunit common to all interleukin-6 type cytokines. The expression of IL-6 is significantly increased near the implantation site in tubes with ectopic gestation as compared with normal.Thus, current study was designed to investigated the expression of gp130 in fallopian tubes wit...

The optimal timing of delivery pregnancies complicated by diabetes is unknown. risk neonatal morbidity and mortality decreases with advancing gestation, which countered an increased stillbirth. objective this study was to compare the stillbirth infant death per week expectant management versus in pregestational (PGD) gestational (GDM). A population based retrospective cohort non-anomalous singl...
