abstract background: gestational diabetes is the second common disorder in pregnancy period, which is detected in 24-28 weeks of gestational age through screening tests in low-risk women. the women with gestational diabetes are prone to prenatal mortality and development of future diabetes. therefore, detection of these individuals in the fi rst trimester and conducting preventive interventions...

background: multiple factors have been suggested for prediction of pregnancy in intracytoplasmic sperm injection (icsi) cycles such as the number of injected oocytes, fertilization rate, embryo morphology and quality of transferred embryos. predictive value of these factors is important in icsi outcome. objectives: to evaluate the role of embryo morphology for prediction of pregnancy in icsi cy...

Early determination of pregnancy viability is essential for women at risk for experiencing ectopic pregnancy or spontaneous abortion. Several markers of pregnancy viability have been identified including serial human chorionic gonadotropin (hCG) monitoring and sonography, in addition to several less commonly available biochemical markers. An ideal test would be readily available, inexpensive an...

BACKGROUND Prediction models for spontaneous pregnancy may be useful tools to select subfertile couples that have good fertility prospects and should therefore be counselled for expectant management. We assessed the accuracy of a recently published prediction model for spontaneous pregnancy in a large prospective validation study. METHODS In 38 centres, we studied a consecutive cohort of subf...

BACKGROUND The predictive value of ovarian reserve tests (ORTs) for spontaneous pregnancy is unclear. Our study aimed to determine whether ORTs have added value to previously identified prognostic factors for spontaneous pregnancy in subfertile ovulatory couples. METHODS A prospective cohort study was performed on 474 subfertile ovulatory couples in two hospitals in Groningen, The Netherlands...

The objective of the present study was to determine the accuracy and the negative prediction value of Pregnancy-Associated Glycoprotein (PAG) at 29 d post artificial insemination by ELISA. Blood serums of multiparous Holstein cows were used (n = 275). Pregnancy diagnosis was carried out by rectal palpation at 40 d and it was considered as reference test. Pregnancy results based on the PAG-ELISA...

Background: Early diagnosis of gestational diabetes is one of the most important applications of taking care of during pregnancy. The current study was done to find the correlation between hemotocrit in the first trimester of pregnancy with gestational diabetes in women who referred to Milad Hospital in Tehran in 2009-2010. Materials and Methods: A prospective cohort study was conducted on 700 ...

BACKGROUND Prediction models have been developed in reproductive medicine to help assess the chances of a treatment-(in)dependent pregnancy. Careful evaluation is needed before these models can be implemented in clinical practice. METHODS We systematically searched the literature for papers reporting prediction models in reproductive medicine for three strategies: expectant management, intrau...

The system for estimating days open for cows with no subsequent lactation was examined to determine if estimates should vary depending on pregnancy diagnosis. Pregnancy diagnosis information was unavailable when the original prediction system was developed, but collection was begun in 2002. New prediction equations were estimated from nearly 1.1 million Holstein lactations for 20-d intervals fr...

BACKGROUND To improve early risk-identification in pregnancy, research on prediction models for common pregnancy complications is ongoing. Therefore, it was the aim of this study to explore pregnant women's perceptions, preferences and needs regarding prediction models for first trimester screening for common pregnancy complications, such as preeclampsia, to support future implementation.
