The aim of the present study was to investigate the relationship between lactate level in vaginal fluid and the latent phase of labour in pregnancies complicated by preterm premature rupture of membranes (PPROM). Seventy pregnant women with PPROM during 28-34 weeks gestation were selected for this prospective observational study. All subjects underwent a pelvic examination involving the insertion of a vaginal speculum, and lactate levels were measured in vaginal fluid samples. The relationship between the lactate levels in the vaginal fluid and the latent phase of the labour was analysed using a logistic regression test. Of the patients, 48 (68.6%) had a latent period of 48 h or less, and 22 patients (31.4%) had a latent period longer than 48 h. The median lactate level was 3.81 mmol/L in patients with a latent period ≤ 48 h, and 3.36 mmol/L in patients with a latent period > 48 h. The lactate level in vaginal fluid was not found to be distinctive in the differentiation of patients according to the duration of the latent phase (receiver operating characteristic or ROC: 0.509; 95% confidence interval or CI: 0.361-0.657; p = 0.904). There was no significant correlation between the lactate level in the vaginal fluid and the transition from the latent phase to the active phase of labour in pregnancies complicated by PPROM. © 2015 Taylor & Francis Group, LLC.

The aim of this study was to evaluate the relationship between placental localisation and perinatal outcomes. This study was performed in a tertiary centre hospital by retrospectively analysing the medical records of patients who were followed up and underwent delivery in the same hospital. The patients were divided into two groups according to the placental locations (central and lateral) in their routine sonographic findings between the 18 and 24 weeks gestation. Out of 1,057 patients, 87.4% (n = 919) had centrally located placentas and 12.6% (n = 133) had laterally located placentas. Preeclampsia was found to be significantly higher in the lateral placental location group (4.5% vs. 1.6%; p = 0.027). There was a significant correlation with foetal growth restriction (FGR), preterm birth rates, low Apgar scores and need for neonatal intensive care unit in the lateral placental location group (p < 0.05). The pregnant women with laterally located placentas should be followed up promptly with special care for the risk of preeclampsia and FGR, and poor neonatal outcomes. © 2015 © 2015 Taylor & Francis Group, LLC.

The aim of this study was to evaluate whether pregnant women with fetal growth restriction (FGR) have higher plasma neopterin and C-reactive protein (CRP) concentrations compared with those with uncomplicated pregnancy. A total of 34 pregnant women with FGR and 62 patients with uncomplicated pregnancy were included. Neopterin and CRP levels were measured at the time of diagnosis. The primary outcome of this study was to compare the neopterin and CRP levels in pregnant women with FGR and those with uncomplicated pregnancies. The secondary outcome of our study was to evaluate the correlation between fetal birth weight and maternal neopterin levels. The serum neopterin levels were significantly elevated in pregnant women with FGR (22.71 ± 7.70 vs 19.15 ± 8.32). However, CRP was not elevated in pregnant women with FGR (7.47 ± 7.59 vs 5.29 ± 3.58). These findings support the hypothesis that pregnancy with FGR is associated with a marked increase in macrophage activation and the natural immune system. © 2015 Informa UK, Ltd. Source

Our aim was to evaluate and compare the diagnostic performance of three methods commonly used for GDM screening: fasting plasma glucose (FPG), two-step 50 g glucose challenge test (GCT), and 75 g glucose tolerance test (GTT) in a randomized study design to predict GDM in the first trimester and determine the best approach in predicting GDM. In a non-blind, parallel-group prospective randomized controlled study; 736 singleton pregnant women underwent FPG testing in the first trimester and randomly assigned to two groups; two-step 50 g GCT and 75 g GTT. GDM diagnosis was made according to Carpenter-Coustan or ADA (American Diabetes Association) criteria in two-step 50 g GCT and 75 g GTT groups, respectively. Subsequent testing was performed by two-step 50 g GCT at 24-28 weeks for screen negatives. After excluding the women who were lost to follow-up or withdrawn as a result of pregnancy loss, 486 pregnant women were recruited in the study. The FPG, two-step GCT, and one-step GTT methods identified GDM in 25/486 (5.1 %), 15/248 (6.0 %), and 27/238 (11.3 %) women, respectively. Area under ROC curves were 0.623, 0.708, and 0.792, respectively. Sensitivities were 47.17, 68.18, and 87.1 %, respectively. Specificities were 77.37, 100, and 100 %, respectively. Positive predictive values were 20.33, 100, and 100 %, respectively. Negative predictive values were 92.29, 97, and 98.1 %, respectively. Until superior screening alternatives become available, the 75 g GTT may be preferred for GDM screening in the first trimester. © 2013 Springer Science+Business Media. Source
