Abstract Background:Mother's physical activity and occupationare two factors thatare supposed to have a role in producing low birth weight and premature birth. Severe physical work is an independent risk factor for premature infants. Thisstudywas designed to evaluate the effect of shiftworkandthe amountof physical activityduring pregnancy on birth weightandgestational age. Methods:In a cross-...
The sequence of reactions which function to incorporate choline into phosphatidylcholine was investigated in lung from fetuses following premature delivery. The rate of [methyl-14C]choline incorporation by rat lung slices into phosphatidylcholine increases following premature delivery at both 20 and 21 days gestation. The increase in choline incorporation is primarily due to an increased specif...
Recent retrospective publications have suggested that cesarean delivery may be beneficial for the extremely premature fetus. This article displays the available evidence and discusses this issue, including many aspects such as the difficulty in deciding when delivery is imminent, the negative impact on maternal morbidity and mortality and the cost to society of such a policy. The available scie...
Maternal hypothyroidism is closely associated with adverse maternal and foetal outcomes. This study aims to analyse the associations between the clinical classification of hypothyroidism and maternal and foetal outcomes, and evaluate the effects of levothyroxine (LT4) supplemental replacement treatment on maternal and foetal outcomes in pregnant women with subclinical hypothyroidism (SCH) or ov...
OBJECTIVE To reassess the evidence for management issues related to the care of women with epilepsy (WWE) during pregnancy, including the risk of pregnancy complications or other medical problems during pregnancy in WWE compared to other women, change in seizure frequency, the risk of status epilepticus, and the rate of remaining seizure-free during pregnancy. METHODS A 20-member committee in...
intraventricular hemorrhage (ivh) is an important cause of brain injury in premature neonates. current study tries to define associated risk factors of ivh in preterm neonates in aliasghar children hospital during 2008 to 2011. in this study, the risk factors have been evaluated in premature neonates with ivh, who had at least one brain sonography since their admission in nicu. a total of 63 pr...
AIMS This study aimed to investigate the association between the methylene tetrahydrofolate reductase (MTHFR) gene C677T and A1298C polymorphisms and premature delivery susceptibility. METHODS With matched age and gender, 108 premature delivery pregnant women as cases and 108 healthy pregnant women as controls were recruited in this case-control study. The cases and controls had same gestatio...
receiver operating characteristics (roc) curves have numerous applications for identifying a cut-off point in diagnostic tests. nonetheless, given that sometimes two cut-off points have to be specified simultaneously, the roc curve can be used to identify such points. the volume under the roc surface (vus) serves as a criterion for the accuracy of diagnostic tests. one of the unfortunate outcom...
