Post-liquefaction normospermic human semen behaves as a weak-gel viscoelastic fluid.

The rheological behavior of human semen is overlooked and essentially unexplored in the scientific literature. Here, we provide the first quantitative experimental evidence that post-liquafaction normospermic human semen behaves as a viscoelastic fluid and the shear moduli can be scaled according to the weak-gel model.

A Novel Splicing Variant of in a Fetus with Achondrogenesis Type II: Interpretation of Pathogenicity of In-Frame Deletions.

Achondrogenesis type II (ACG2) is a lethal skeletal dysplasia caused by dominant pathogenic variants in . Most of the variants found in patients with ACG2 affect the glycine residue included in the Gly-X-Y tripeptide repeat that characterizes the type II collagen helix. In this study, we reported a case of a novel splicing variant of in a fetus with ACG2.

Isolated Upward Rotation of the Fetal Cerebellar Vermis (Blake's Pouch Cyst) Is a Normal Variant: An Analysis of 111 Cases.

Introduction: The objective of the study was to provide more detailed data about fetal isolated upward rotation of the cerebellar vermis rotation (Blake's pouch cyst) in particular regarding pregnancy outcome.

Methods: This is a retrospective study of all cases of fetal isolated upward rotation of the cerebellar vermis (URCV) diagnosed in 3 referral centers in Italy from January 2009 to November 2019. Whenever possible, prenatal magnetic resonance imaging (MRI) was performed and a fetal karyotype was obtained.

Prospective detection and differential diagnosis of cystic posterior fossa anomalies by assessing posterior brain at 11-14 weeks.

Background: The role of the first-trimester scan has expanded from aneuploidy screening to the diagnosis of fetal malformations. Abnormal appearance of the posterior brain at 11-14 weeks gestation is a marker of cerebral anomalies; in fact an increased amount of fluid, particularly when the choroid plexus of the fourth ventricle is not visible and only 2 brain spaces instead of 3 are seen, may indicate the presence of cystic or cyst-like posterior fossa anomalies, such as Blake's pouch cyst or Dandy-Walker malformation.

Objective: The purpose of this study was to assess the role of ultrasound scanning in the identification of cystic posterior fossa anomalies at 11-14 weeks gestation.

Cleft Palate with or without Cleft Lip: The Role of Retronasal Triangle View and Maxillary Gap at 11-14 Weeks.

Objective: To evaluate the presence of maxillary gap (MG) and abnormal retronasal triangle (RT) as markers of cleft palate (CP) with and without cleft lip in the first trimester and to assess their association with the type of orofacial cleft (OC).

Methods: The RT and the mid-sagittal view of the face were evaluated retrospectively by two operators in 26 fetuses with OC and in 80 normal controls to detect abnormal RT and/or MG. The agreement between operators was calculated.

Knowledge of Human Cytomegalovirus Infection and Prevention in Pregnant Women: A Baseline, Operational Survey.

Currently, the only efficient way to prevent human Cytomegalovirus (HCMV) infection in pregnancy is primary prophylaxis through hygienic measures. So, we evaluated knowledge of HCMV and its prevention in a group of pregnant women. An anonymous questionnaire with multiple-choice answers was administered to all pregnant women who were followed up at the Obstetrics and Gynecology Unit of "Pugliese-Ciaccio Hospital," a third-level hospital in Catanzaro (Southern Italy), from November 2015 to March 2016.

Cervical pessary for preventing preterm birth in twin pregnancies with short cervical length: a systematic review and meta-analysis.

Objective: To evaluate the effectiveness of cervical pessary for preventing spontaneous preterm birth (SPTB) in twin pregnancies with an asymptomatic transvaginal ultrasound cervical length (TVU CL) in the second trimester.

Methods: We performed a meta-analysis including all randomized clinical trials (RCTs) comparing the use of cervical pessary (i.e.

A case report of Schistosoma haematobium infection in a pregnant migrant raises concerns about lack of screening policies.

Pregnant women with urinary schistosomiasis should be treated, but screening is not implemented in migrants. We report herein a case of a migrant diagnosed late into pregnancy, after diagnosis was made in her husband. Praziquantel was safe and effective.

Increased TGF-β: a drawback of tracheal occlusion in human and experimental congenital diaphragmatic hernia?

Survivors of severe congenital diaphragmatic hernia (CDH) present significant respiratory morbidity despite lung growth induced by fetal tracheal occlusion (TO). We hypothesized that the underlying mechanisms would involve changes in lung extracellular matrix and dysregulated transforming growth factor (TGF)-β pathway, a key player in lung development and repair. Pulmonary expression of TGF-β signaling components, downstream effectors, and extracellular matrix targets were evaluated in CDH neonates who died between birth and the first few weeks of life after prenatal conservative management or TO, and in rabbit pups that were prenatally randomized for surgical CDH and TO vs.

Stomach position versus liver-to-thoracic volume ratio in left-sided congenital diaphragmatic hernia.

Objective: To describe a new grading method for stomach position (SP) in fetuses with left-sided congenital diaphragmatic hernia (L-CDH) using ultrasound and to correlate SP to liver position and to liver-to-thoracic cavity volume ratio (LiTR) using magnetic resonance imaging.

Methods: SP were graded at the level of the 4-chamber view as following: grade 1-to-4 for stomach not visualised, visualised anteriorly at the apex of the heart, stomach showing abdominal structures anteriorly and stomach with its larger part posterior to the level of the atrial-ventricular heart valves, respectively. The LiTR was calculated and correlated to SP using the Mann-Whitney U test.

Post-mortem high-field magnetic resonance imaging: effect or various factors.

Purpose: To evaluate image quality and diagnostic accuracy of high-field post-mortem (PM) magnetic resonance imaging (MRI) on fetuses below 20 weeks of gestation before and after the freeze-thaw process.

Materials And Methods: Nine fetuses were scanned with three different scanning procedures: "fresh", just after termination of pregnancy (TOP), "non-fresh short scan" and "non-fresh long scan" after being kept at -20 °C, followed by a conventional autopsy. The brain, thorax except the heart, heart and abdomen were studied.

Signaling molecules in the fetal rabbit model for congenital diaphragmatic hernia.

Rationale And Objectives: Little is known about molecular changes in lungs of fetal rabbits with surgically induced diaphragmatic hernia (DH). Therefore, we examined in this model gene expressions of pivotal molecules for the developing lung.

Methods: At day 23 of gestation, DH was created in 12 fetuses from 4 does.

Successful treatment of a severe second trimester fetomaternal hemorrhage by repeated fetal intravascular transfusions.

Objective: It was the aim of this study to report a case of fetomaternal hemorrhage (FMH) that was successfully treated with fetal intravascular transfusions in which the middle cerebral artery peak systolic velocity (MCA-PSV) detected fetal anemia.

Methods: A massive FMH occurred twice in a healthy 33-year-old pregnant woman at 26 and 29 weeks of gestation with no evident cause. Four repeated intravascular transfusions were performed.

Is uterine artery embolization for cervical ectopic pregnancy always safe?

The study objective was to assess the feasibility and the efficacy of bilateral uterine artery embolization (BUAE) for the treatment of cervical pregnancy. The design was a series of 3 cases of viable cervical pregnancy diagnosed by transvaginal ultrasonography and treated by means of BUAE and subsequent uterine curettage. Three women with viable cervical pregnancy underwent BUAE and subsequent uterine curettage in the department of obstetrics and gynecology, High Risk Pregnancy Center, University "Federico II" of Naples.

Cervical fetal fibronectin as a predictor of first trimester pregnancy outcome in unexplained recurrent miscarriage.

Objective: To determine whether cervical fetal fibronectin is a reliable predictor of first trimester pregnancy outcome in patients with unexplained recurrent miscarriage.

Study Design: A prospective observational study was carried out on 49 pregnant women with a history of unexplained recurrent miscarriage. In all participants the presence of fetal fibronectin in the cervical secretion was determined with a qualitative rapid immunoassay.

Fetal fibronectin as predictor of successful induction of mid-trimester abortion.

Background: Fetal fibronectin (FFN) in cervical secretion is one of the most effective markers of pre-term and term delivery. The presence of FFN in cervicovaginal secretions has recently been shown to reflect cervical state and an uncomplicated induction of labor at term. This study was designed to determine whether FFN could be a biochemical marker to predict the response to prostaglandins in early mid-trimester abortion.
