Aquaporins: Brand new indicators for man (inside)male fertility in issues along with fowl?
Objective To investigate the impact of a previous cesarean delivery on pregnancy outcomes of in vitro fertilization and frozen-thawed embryo transfer (FET). Methods The clinical data of 1 179 patients who received in vitro fertilization and FET in Tianjin Central Hospital of Gynecology Obstetrics from January 2014 to May 2019 and had a history of the previous delivery were retrospectively analyzed. The patients were divided into four groups according to different previous delivery history and the number of embryo transferred group A (single embryo transfer group with cesarean delivery history, n=338), group B (single embryo transfer group with vaginal delivery history, n=78), group C (double embryo transfer group with cesarean delivery history, n=444), and group D (double embryo transfer group with vaginal delivery history, n=319). Chitosan oligosaccharide manufacturer The 1∶1 propensity score based on age, body mass index (BMI), infertility duration, basal FSH, basal LH, number of oocytes retrieved and high-quality embryo rate was used to match uble embryo transfer in patients with a cesarean delivery history is low. The neonatal birth weight is not related to the history of the cesarean section. It is recommended that patients with a cesarean delivery history choose elective single embryo transfer to ensure the success rate and to reduce the risk.
The primary outcome was to compare the diagnostic accuracy of neonatal small for gestational age (SGA) by the Hadlock and Fetal Medicine Foundation (FMF) charts in our cohort, followed by the ability to predict composite severe neonatal outcomes (SNO) in pregnancies with preterm prelabor rupture of membranes (PPROM).

This study was a secondary analysis of a prospective cohort of pregnancies with PPROM from 2015 to 2018, from 23 to 36 completed weeks of gestation. Sensitivity, specificity, and positive and negative predictive values for the primary and secondary outcomes of the Hadlock and FMF fetal charts were calculated. The discriminatory ability of each chart was compared using the area under the receiver's operating curves of clinical characteristics.

Of the 106 women who met the inclusion criteria, 48 (45%) were screened positive using the FMF fetal growth chart and 22 (21%) were screened positive using the Hadlock chart. SGA was diagnosed in 12 infants (11%). Both fetal growth charts had comparable diagnostic accuracies and were statistically significant predictors of SGA (Hadlock area under the receiver operating characteristic curves [AUC], 0.76, risk ratio [RR], 7.6, 95% confidence interval [CI], 2.5-23; and FMF AUC, 0.76 RR, 13.3 95%CI 1.8-99.3). Both growth standards were poor predictors of SNO.

The Hadlock and FMF fetal growth charts have a similar accuracy to predict SGA in pregnancies complicated by PPROM. The FMF fetal growth chart may result in a 2-fold increase in positive screens, potentially increasing fetal surveillance.

Open or percutaneous renal stone surgery can have an adverse effect on the collecting system of the kidney. We evaluated retrograde intrarenal surgery outcomes in patients with ?30 mm renal stones who had open or percutaneous renal stone surgery history.

A total of 707 patients who underwent retrograde intrarenal surgery treatment were included in this study. Fifty-six patients had open or percutaneous renal stone surgery history (Group 1) and the remaining did not (Group 2, n=651). The groups were compared in terms of age, stone size, stone-free rates, and complications.

The mean age of the patients was 51.16±14.8 and 45.95±14.6 years in Groups 1 and 2, respectively(p=0.008). The mean stone size was 14.97±6.1 mm and 16.47±6.9 mm in Groups 1 and 2, respectively(p=0.107). The stone-free rates were 71.4% and 84.1% in Group 1 and 2 respectively and it was significantly higher in Group 2 (p=0.013). The overall rate of postoperative complications was higher in Group 1(p=0.019), But there was no difference between the two groups in terms of Clavien 1-2 and 3-4a complication rates.

Our results showed that having a history of open or percutaneous renal stone surgery has a negative effect on the success and complication rates in retrograde intrarenal surgery . Therefore, patients should be well informed before this operation.

We aimed to determine the presence of subclinical atherosclerosis using carotid intima-media thickness (CIMT) and biochemical parameters in children and adolescents with congenital adrenal hyperplasia (CAH).

Thirty-four patients with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency on regular glucocorticoid treatment for ? 3 years and 31 healthy subjects were included in the study. The patients were divided into two groups according to the degree of control of the clinic, laboratory and radiological parameters as a) uncontrolled [n= 22; with increased height velocity (HV) Standard Deviation Score (SDS) (? 2 SDS), advanced bone age, serum 17-OH progesterone <2.0 and ?10.0 ng/mL or androstenedione <0.3 and ? 3.0 ng/mL] or b) controlled [n= 12; with HV SDS < 2, Bone age (BA)/ Chronologic Age (CA) ratio < 1.2, serum 17-OH progesterone between 2 - 10 ng/mL and androstenedione between 0.3 ? 3.0 ng/mL]. Ultrasonographic examination of carotid artery was performed by the same radiologist using a B-mode ultrasound system.

There was no significant difference between the CAH and control groups in terms of median (IQR) CIMT values [0.47 (0.05) mm, 0.47 (0.07) mm; respectively, p> 0.05]. When subgroup comparisons were done in terms of median (IQR) CIMT values, there was no significant difference among the controlled, uncontrolled and healthy control groups [0.45 (0.03) mm, 0.47 (0.04) mm, 0.47 (0.07) mm; respectively, p> 0.05]. In addition, CIMT levels were similar according to gender and disease control status.

In this study, the CIMT values of CAH cases were similar to those of healthy subjects.
