Substance Abuse in Pregnancy.

Addiction is a primary, chronic disease of brain reward, motivation, memory and related circuitry. Like many other chronic diseases, addiction often involves cycles of relapse and remission. It is key that clinicians understand it as such and treat it appropriately with evidence-based interventions including medication-assisted treatment.

Localization and expression of CTRP6 in ovary and its regulation by FSH in porcine granulosa cells.

C1q/tumor necrosis factor-related protein 6 (CTRP6) is a newly identified adiponectin paralog with modulating effects on metabolism and inflammation. CTRP6 transcript is detected in human ovarian tissue. However, the expression pattern and function of CTRP6 on ovary have been rarely studied. In the present study, we preliminarily examined the structure feature and function of CTRP6 in porcine gran...

Translation, cultural adaptation, and validation of Australian pelvic floor questionnaire in a Turkish population.

The aims of the study were the translation, cultural adaptation, and validation of self-administered Australian Pelvic Floor Questionnaire (APFQ) in a Turkish population.

Is fasting plasma glucose in early pregnancy a better predictor of adverse obstetric outcomes than glycated haemoglobin?

To determine, in a multi-ethnic cohort, the suitability of first-trimester fasting plasma glucose and HbA1c levels in non-diabetic range to identify women without diabetes at increased pregnancy risk.

Which semen analysis correlates with favorable Intracytoplasmic morphologically selected sperm injection (IMSI) outcomes?

To assess whether a correlation exists between different sperm pathologies and Intracytoplasmic morphologically selected sperm injection (IMSI) outcomes.

Role of Endometrial Sampling in Cases with Asymptomatic Cervical Polyps.

Cervical polyps are benign neoplasms of the cervix and frequently asymptomatic; however, they may cause intermenstrual, postcoital, and postmenopausal bleeding. The excision of cervical polyps and necessity of endometrial sampling is remain controversial. The objective of our study was to determine the association between cervical polyps and smear and endometrial pathologies. 221 patients were inc...

Gonadal steroids and energy availability during ovarian maturation stages of the Amazonian pirarucu Arapaima gigas (Teleostei: Osteoglossidae) in the wild.

The Amazonian pirarucu, Arapaima gigas, belongs to a phylogenetically basal group of teleosts (family Osteoglossidae). The commercial importance and the overexploited status of natural stocks of A. gigas brought the interest to rear it in the Amazon region, but rearing techniques are not fully understood to obtain reproduction success. Gonadal steroids (plasma and cephalic liquid), lipids and prot...

Neurodevelopmental outcomes at five years after early-onset fetal growth restriction: Analyses in a Dutch subgroup participating in a European management trial.

The objective of this study is to explore developmental outcomes at five years after early-onset fetal growth restriction (FGR).

Fetal fibronectin test for threatened preterm delivery 48h after admission: Cost-effectiveness study.

The aim of this work was to assess the cost-effectiveness of the fetal fibronectin (fFN) test at 48 h after admission for threatened preterm delivery to promote early discharge.

Effect of endometrial injury on in vitro fertilization pregnancy rates: a randomized, multicentre study.

To determine if endometrial injury prior to the first or second in vitro fertilization (IVF) cycle affects clinical pregnancy rates.

Three-dimensional ultrasound in the diagnosis and the classification of congenital uterine anomalies using the ESHRE/ESGE classification: a diagnostic accuracy study.

To estimate the diagnostic accuracy of three-dimensional ultrasonography (3D US) compared to hysteroscopy/laparoscopy, in the investigation of uterine congenital anomalies using the ESHRE/ESGE classification of female genital tract congenital anomalies.

Hysterectomy: All obstetrician-gynecologists should learn to perform it.

Rudnicki et al. described that due to the increasing popularity of various non-surgical modalities and laparoscopic/robotic-assisted hysterectomies, the number of hysterectomies that a trainee can perform has decreased. They ask "Do all trainees in obstetrics and gynecology still need to learn to perform hysterectomy?" In our opinion, yes, all trainees still need to learn to perform abdominal hys...

Intrauterine administration of human chorionic gonadotropin improves the live birth rates of patients with repeated implantation failure in frozen-thawed blastocyst transfer cycles by increasing the percentage of peripheral regulatory T cells.

Repeated implantation failure (RIF) frustrates both patients and their clinicians. Our aim was to observe the effects of intrauterine administration of human chorionic gonadotropin (hCG) on pregnancy outcomes of patients who received frozen-thawed embryo transfer (FET).

Treatment of ovarian endometrial cysts in the context of recurrence and fertility.

An approach to ovarian endometrial cysts has changed considerably during recent years, especially in regard to treatment of recurrent endometriosis, fertility sparing and infertility management. Surgical treatment is the primary therapeutic option. The most efficient types of treatment are radical procedures involving adhesiolysis, removal of the cyst along with its capsule and any remaining endom...

Enoxaparin (or plus aspirin) for the prevention of recurrent miscarriage: A meta-analysis of randomized controlled studies.

Enoxaparin treatment has emerged as an important approach to prevent recurrent miscarriage, but the use of enoxaparin for the prevention of recurrent miscarriage has not been well established. We conduct a systematic review and meta-analysis to evaluate the efficacy of enoxaparin to prevent recurrent miscarriage. PubMed, Embase, and the Cochrane Central Register of Controlled Trials are searched. ...

Mode of delivery of twin pregnancies with the first twin in breech position after the introduction of a policy of planned caesarean delivery for nulliparous women.

To evaluate the impact of the mode of delivery of twin pregnancies with the first twin in breech position for all parities combined after introduction of a policy of planned caesarean section in 38 weeks' gestation in nulliparas.

NO-synthase activity in mitochondria of uterus smooth muscle: identification and biochemical properties.

Information about the catalytic and kinetic properties of mitochondria NO-synthase from uterus smooth muscle is missing currently. According to the data on MitoTracker Orange CM-H2TMRos and 4-аmino-5-methylamino-2',7'-difluorescein, diaminofluorescein-FM (DAF-FM) dye co-localization in uterine smooth muscle cells, presented in this paper, NO can be synthesized in their mitochondria. High activity...

A hyperandrogenic environment causes intrinsic defects that are detrimental to follicular dynamics in a PCOS mouse model.

Polycystic ovary syndrome (PCOS) is a common cause of infertility. Hyperandrogenism is both a major symptom and key diagnostic trait of PCOS; however, the direct impact of this androgen excess on ovarian dynamics is unclear. By combining a DHT-induced PCOS mouse model with an ex vivo follicle culture system, we investigated the impact of hyperandrogenism on ovarian function. Ovaries from PCOS mice...

Management options for a patient with squamous cell carcinoma arising in a mature cystic teratoma of the ovary.

Mature cystic teratomas, also referred to as dermoid cysts, are one of the commonly occurring ovarian germ cell tumors. Malignant transformation of a germ cell tumor occurs approximately 1-2% of the time. Treatment options vary by stage and are not well outlined in the literature. Here we report a case of a perimenopausal female who presented with increasing abdominal girth and an elevated CA-125....

Pure large cell neuroendocrine carcinoma of ovary: A rare clinical entity.

Large cell neuroendocrine carcinoma (LCNEC) of the ovary is a rare tumour. Its pure form without any associated surface epithelial stromal or germ cell component is more rarely seen. Its prognosis is generally very poor even when the diagnosis is made at an early stage. We report a case of pure large cell neuroendocrine tumour of ovary. The patient was a 73-year-old woman with symptom of pelvic pa...

Recurrence of endometrial carcinoma presenting as vulvar lesions.

Endometrial cancer is the most common gynecological malignancy in developed countries. Although this cancer generally carries a good prognosis, 10%-15% of patients will suffer recurrent disease and vulvar metastasis is extremely rare. A 60-year-old female (G3P3) was referred to the vulvo-vaginal clinic in Shaare Zedek Medical Center, Jerusalem, Israel, with a 3-month history of painful vulvar lesi...

Towards a circulating marker of hepato-visceral fat excess: S100A4 in adolescent girls with polycystic ovary syndrome - Evidence from randomized clinical trials.

S100A4 is a marker of subcutaneous adipose tissue dysfunction. Polycystic ovary syndrome (PCOS) is often driven by hepato-visceral adiposity. PCOS phenotypes are normalized more by reduction of central fat with spironolactone/pioglitazone/metformin (SPIOMET) than by oral contraceptive (OC) treatment. We studied whether circulating S100A4 concentrations are high in adolescents with PCOS and, if so,...
