Background : Pre-eclampsia is one of the most serious complications in pregnancy and is one of the major causes of maternal death during pregnancy. Therefore, its prediction has special importance and many studies have been performed on different materials, which may be useful for its prediction. The purpose of the present study was to evaluate the urine calcium to creatinine ratio for predic...
Background and Objective: Early prediction of prolonged pregnancy for prevention of fetal asphyxia is important. The present study aimed to examine transvaginal ultrasonographic measurement of the cervical length at week 37 as a predictor of prolonged pregnancy. Materials and Methods: This study was a descriptive-correlated design of ultrasound examination at week 37 of gestation in 126 singlet...
objective: to investigate the clinical advantage of several prognostic factors for predicting preterm delivery. materials and methods: eighty and six patients with a singleton pregnancy admitted to vali-asr hospital underwent genetic amniocentesis between the 15th and 23th weeks were included in this study. maternal serum c-reactive protein (crp), transvaginal sonographic measurement of cervica...
assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (art). the current trend in human in vitro fertilization/embryo transfer (ivf/et) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...
Background and purpose: The newborn birth weight is an important indicator for prenatal care, general health and fetal viability. The aim of this study was to assess the relationship between pre-pregnancy BMÏ and pregnancy weight gain on neonatal birth weight. Materials and methods: Ïn a descriptive-analytical study, 16-40 years old pregnant mothers registered to prenatal clinics of Lowlagar...
BACKGROUND Pre-eclampsia is a form of hypertensive disorder of pregnancy. It is a common cause of both maternal and perinatal morbidity and mortality in both developed and developing countries. OBJECTIVE To evaluate the possibility of early prediction of hypertensive disorders of pregnancy using single estimation of serum protein, creatinine and uric in serum samples of healthy primigravidae ...
STUDY QUESTION Are there improvements in the accuracy of prediction of ectopic pregnancy (EP) in women with early symptomatic pregnancy using human chorionic gonadotrophin (hCG) curves when clinicians consider visits beyond the first 48 h after initial presentation? SUMMARY ANSWER Two hCG values, measured 48 h (2 days) apart, are often not sufficient to accurately predict the outcome of a wom...
This study aimed to establish a method of screening for pregnancy hypertension by a combination of maternal variables, including mean arterial pressure, uterine artery pulsatility index, pregnancy-associated plasma protein-A, and placental growth factor in early pregnancy. The base-cohort population constituted of 7797 singleton pregnancies, including 34 case subjects who developed preeclampsia...
background: the value of serial measurement of serum ß subunit of human chorionic gonadotropin (ßhcg) and ultrasonography in the early diagnosis of ectopic pregnancy has well established. objective: the objective of this study was to explore the diagnostic value of raising level of serum ßhcg, single measurement of progesterone (p) and estradiol (e2) in early diagnosis of ectopic pregnancy. mat...
