RESUMEN
OBJECTIVES: We aimed to determine if superb microvascular imaging (SMI) can predict response to uterine artery embolization (UAE) as compared with power Doppler ultrasound. METHODS: The blood flow and the volume of the dominant leiomyoma was evaluated by power Doppler ultrasonography (PDUS) and SMI 1 day before and 3 months after the UAE procedure. SMI and PDUS blood flow were classified to 4 grades of vascularity. The change in fibroid volume in Grades 0-2 (hypovascular group) was compared to the hypervascular Grade 3 group. RESULTS: Twenty-eight women (mean age, 40.9 years; range, 33-53 years) were examined with PDUS and SMI before and 3 months after UAE. The volume reduction was statistically significantly higher hypervascular group (P < .05). When we accept 30% or more volume reduction as a good response to UAE, the positive predictive value, negative predictive value, sensitivity, specificity, and accuracy of SMI were 100, 64, 73.6, 100, and 82.1%, respectively. There was excellent agreement between the two blinded observers in SMI measurements. CONCLUSIONS: SMI, with its high reproducibility, provides further microvessel information than PDUS in uterine fibroids. It may be a useful tool in prediction of response to UAE treatment and improve counseling and patient selection for UAE versus medical or surgical treatment options.

Our aim was to assess the relationship between gestational diabetes and glucose intolerance regarding maternal serum PAPP-A and free ß-hCG concentrations in first trimester pregnancies. This study was conducted on 278 women between 18-45 years old with singleton pregnancies. The subjects were divided into four groups, according to their 50 and 100 g OGTT results. Group 1 was the Control Group, Group 2 with positive 50 g OGTT results, but negative 100 g, Group 3 had gestational diabetes after testing with 50 g OGTT (≥180 mg/dl) or with 100 g OGTT. Finally Group 4 was made of women with a one single high glucose level after testing with 100 g OGTT. These groups were analysed in terms of OGTT results. In the GDM group, serum PAPP-A concentrations were significantly lower when compared with the Control Group's (p = 0.015). There was either no significant differences regarding free ß-hCG concentrations among the groups. GDM rate is 21.1%, the patients with GDM had significantly low concentrations of serum PAPP-A but their f ß-hCG concentrations did not change. Our results are supported by several studies. However, we need greater numbered studies for exact results.IMPACT STATEMENTWhat is already known on this subject? Pregnancy associated plasma protein A (PAPP-A) is produced by the placenta in pregnancy. PAPP-A cleaves insulin-like growth factor (IGF) binding proteins. It would appear to have a role in regulating IGF bioavailability in pregnancy. This is important as the IGF axis plays a critical role in fetal growth, and placental growth and function during pregnancy. Some studies have reported that PAPP-A levels were impaired among women who subsequently developed GDM.What do the results of this study add? The patients with GDM had significantly low concentrations of serum PAPP-A but their free ß-hCG levels did not change.What are the implications of these findings for clinical practice and/or further research? By looking at PAPP-A concentrations, we can predict patients that will be gestational diabetic and take precautions to protect the babies health, such as their diet or exercise.

OBJECTIVE: The aim of this study was to evaluate preeclampsia progression of isolated proteinuria and associations with pregnancy outcome. METHOD: We performed a retrospective analysis in patients who were hospitalized for evaluation of new onset proteinuria without hypertension after 20 weeks of gestation between January 2012 and January 2014. One hundred fifty-seven patients who met the inclusion criteria were enrolled the study. RESULTS: After detection of new onset proteinuria, 53 of 157 (33.7%) patients developed preeclampsia and the incidence of gestational proteinuria was found to be 0.33%. Twenty-four hours urine proteinuria testing results were significantly higher in preeclampsia (PE) group compared with the gestational proteinuria (GP) group (p < 0.01). Patients who developed preeclampsia delivered significantly earlier than the GP group (p < 0.01). The weights of the infants born to mothers in the PE group were significantly lower than the other group (p < 0.01). CONCLUSION: The incidence of gestational proteinuria was lower than the previous studies. Preeclampsia developed in 33% of patients with new onset proteinuria in pregnancy. In patients who developed PE had significantly higher proteinuria, lower delivery time and birth weight in their infants. Therefore, patients with new onset proteinuria should be followed-up for preeclampsia development and associated morbidities.
