Purpose: In this study, we aimed to compare the changes in the number, yield, and the percentage of karyotyping indications of the invasive prenatal diagnostic tests between the periods before and after cell-free fetal DNA was introduced to clinical use.

Method: The number of invasive prenatal diagnostic procedures such as amniocentesis and chorionic villus sampling, indication percentages and karyotype results in the periods before (January 1, 2009-December 31, 2010), (n = 1412) and after (January 1, 2016-December 31, 2017), and (n = 593) the introduction of cell-free fetal DNA was retrospectively evaluated.

Results: When compared with the period before cell-free fetal DNA came into clinical use, the number of invasive prenatal diagnostic tests decreased by 58% while their yield was found to have increased (4.

Background: The only definitive treatment for twin-to-twin transfusion syndrome is minimally invasive fetoscopic surgery for the selective coagulation of placental blood vessels. Fetoscopic surgery is a technically challenging operation, mainly due to the poor visibility conditions in the uterine environment. We present the design of an algorithm for the computerized enhancement of fetoscopic video and show that the enhanced video increases the ability of human users to identify blood vessels within fetoscopic video rapidly and accurately.

Article Synopsis
  • Twin-to-twin transfusion syndrome (TTTS) impacts pregnancies with shared placentas and can be treated using fetoscopic laser photocoagulation, but identifying blood vessels in surgery can be challenging due to video artifacts.
  • Researchers collected intraoperative videos from TTTS surgeries and trained a deep-learning neural network to segment placental blood vessels, using both expert and novice human ratings for comparison.
  • The neural network demonstrated high accuracy in identifying blood vessels, surpassing novice raters, suggesting that it can improve surgical video quality and assist in the TTTS treatment process.

The aim of the study was to evaluate the fatty acid-binding protein-4 (FABP4) and irisin concentrations in women with polycystic ovary syndrome (PCOS). Forty-nine women with PCOS, diagnosed according to Rotterdam criteria and 39 healthy women matched for body mass index (BMI) and age. Serum irisin and plasma FABP4 concentrations were measured in both groups.

To evaluate placental elasticty in women with gestational diabetes mellitus (GDM) and non-diabetic controls. Thirty-three pregnant women with GDM according to the current criteria of the American Diabetes Association and 43 healthy pregnant women who were admitted to the antenatal clinic were recruited for this case-control study. Elasticity values of both the peripheral and the central parts of the placentas of the patients in both groups were determined by shear wave elastography (SWE) imaging.

The aim of this study was to determine whether homocysteine (hcy) concentrations in embryo culture media correlate with pregnancy outcome in assisted reproductive technology (ART) cycles. Forty patients who underwent single embryo transfer at the infertility clinic of a tertiary care center were recruited for this case-control study. Spent embryo culture media from all patients were collected after single embryo transfer on day 3 (n = 40).

Objective: Early-onset pre-eclampsia is primarily associated with placental dysfunction, whereas late-onset pre-eclampsia is defined as a maternal constitutional disorder. As a protein cosynthesized with vasopressin, copeptin is a potential marker of metabolic syndrome and insulin resistance, which shares similar risk factors with pre-eclampsia. The aim of this study was to investigate the copeptin levels in patients with early-onset and late-onset pre-eclampsia.

Adenomyosis is described as the benign invasion of endometrium into the myometrium, with endometrial glands and stroma surrounded by the hypertrophic and hyperplastic myometrium. It may affect 20% of female population and most widely seen among perimenopausal and multiparous women. Its etiopathogenesis, diagnosis, clinical findings and current various treatment options will be discussed in this article.

Purpose: To establish a reference range for the intracranial translucency (IT).

Methods: In this prospective study, we examined 596 singleton fetuses at 11-14 weeks of gestation using transabdominal ultrasonography. The distribution curves of the anterior-posterior diameter of the IT were established according to the gestational weeks, and the percentiles for 11-14 weeks of gestation were calculated.

Objective: The aim of the present study is to investigate whether alterations in the serum levels of apelin and YKL-40 differ between early and late onset pre-eclampsia and whether there is a correlation between apelin and YKL-40 in women who subsequently develop early and late pre-eclampsia.

Materials And Methods: A total number of 80 pregnant women, 40 with normal pregnancy and 40 with pre-eclampsia, were included in the present study. Both the normal pregnant and pre-eclamptic subjects were subdivided into two groups.

Prenatal diagnosis of a congenital coronary artery fistula between the left coronary artery and the right ventricle was established at 28 weeks of gestation. Hydrops fetalis developed during follow-up and the baby died on the first day after delivery. It is rare for coronary artery fistulas to become symptomatic during fetal life.

Human ovary is commonly the target of an autoimmune attack in cases of organ- or non-organ-specific autoimmune disorders. Hashimoto's thyroiditis (HT) is likely to be associated with ovarian dysfunction and diminished ovarian reserve. In this study, we aimed to evaluate the possible negative association between this significantly prevalent autoimmune disease and the ovarian reserve.
