Few studies focused on unwanted pregnancy and predictive factors in the late age of reproduction. This study applied feed-forward neural network algorithm with ten-sigmoid function in a hidden and an output layer with 150 neurons to develop a predictive model for type of pregnancy. Data of 1404 women in Khuzestan province of Iran in age 35 or more were collected and eight attributes were select...

The physiological changes of pregnancy may predispose females to develop sleep-disordered breathing (SDB) or protect against it. Studies evaluating outcomes of SDB symptoms in pregnancy are scarce. The goal of this study was to evaluate the prevalence of SDB symptoms in pregnancy and their relationship with pregnancy and neonatal outcomes. A cross-sectional survey of randomly selected immediate...

Stillbirth is one of the most common adverse pregnancy outcomes in the United States, occurring in one out of every 200 pregnancies. There is a paucity of information on the outcome of pregnancies after stillbirth. Prior stillbirth is associated with a twofold to 10-fold increased risk of stillbirth in the future pregnancy. The risk depends on the etiology of the prior stillbirth, presence of f...

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...

This study assessed the effects of gonadotropin-releasing hormone (GnRH) treatment on Day 5 (Day 0 = estrus) on luteal blood flow and accuracy of pregnancy prediction in recipient cows. On Day 5, 120 lactating Holstein cows were randomly assigned to a control group (n = 63) or GnRH group treated with 100 μg of GnRH agonist (n = 57). On Days 3, 5, 7, and 14, each cow underwent ultrasound examina...

OBJECTIVE To assess the accuracy of first trimester soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) in predicting pregnancy hypertension and pre-eclampsia; and compare with the accuracy of routinely collected maternal and clinical risk factors. STUDY DESIGN In this population-based cohort study, serum sFlt-1 and PlGF levels were measured in first trimester in 2,...

Findings of a recent clinical study showed indomethacin has lower plasma levels and higher steady-state apparent clearance in pregnant subjects when compared to those in non-pregnant subjects reported in separate studies. Thus, in the current work we developed a pregnancy physiological based pharmacokinetic/pharmacodynamic (PBPK/PD) model for indomethacin to explain the differences in indometha...

Preeclampsia, a cardiovascular disorder of late pregnancy, is characterized as a low-renin hypertensive state relative to normotensive pregnancy. Because other nonpregnant low-renin hypertensive disorders often exhibit and are occasionally dependent on elevated arginine vasopressin (AVP) secretion, we hypothesized a possible use for plasma AVP measurements in the prediction of preeclampsia. Cop...

OBJECTIVE To investigate the predictive capacity of immunoglobulin G ASA (direct MAR test) for spontaneous ongoing pregnancy in subfertile couples. DESIGN Prospective cohort study. SETTING Nine fertility centers in The Netherlands. PATIENT(S) Consecutive ovulatory subfertile couples. INTERVENTION(S) A basic fertility workup, including a mixed agglutination reaction test for IgG (MAR tes...
