OBJECTIVE: Despite growing endovascular experience within the vascular surgery community, some catheter-based interventions - such as uterine artery embolization (UAE) - remain outside the clinical scope of most vascular surgeons, owing in part to established referral patterns and limited awareness among referring colleagues. We present our experience with a vascular surgery-based, multidisciplinary UAE program at an academic tertiary referral center. METHODS: In a collaborative effort between vascular surgery and gynecology, a Pelvic Vascular Disease Program has been established to provide palliative, prophylactic, and therapeutic embolizations including, but not limited to, UAE...

Rationale: The availability of therapeutics to treat pregnancy complications is severely lacking, mainly due to the risk of harm to the fetus. In placental malaria, Plasmodium falciparum- infected erythrocytes (IEs) accumulate in the placenta by adhering to chondroitin sulfate A (CSA) on the surfaces of trophoblasts. Based on this principle, we have developed a method for targeted delivery of payloads to the placenta using a synthetic placental CSA-binding peptide (plCSA-BP) derived from VAR2CSA, a CSA-binding protein expressed on IEs...

Objectives To prospectively estimate the association of preconception antiphospholipid antibodies (aPL) with subsequent pregnancy loss using a cohort design. aPL have been associated with recurrent early pregnancy loss (EPL) prior to 10 weeks in previous case-control studies. Prospective ascertainment of pregnancy loss is challenging, as most women do not seek care prior to EPL. Methods Secondary analysis of the Effects of Aspirin in Gestation and Reproduction trial of preconception low-dose aspirin. Preconception anticardiolipin (aCL) and anti-β2-glycoprotein-I (a-β2-I) were assessed in 1208 women with one or two prior pregnancy losses and no more than two prior live births...

In this report, we propose a study protocol capable of improving IVF outcomes in subfertile women with expected normal ovarian response. This proposal derives from conflicting published data and observations in our daily practice, concerning the negative impact of progesterone (P4) elevation at the day of oocyte triggering on pregnancy outcomes. Our hypothesis points to the combination of two previous "suspects" of reduced success after assisted reproduction techniques (ART) - the endometrium ultrasonographic parameters and P4 elevation at the day of oocyte triggering on their impact on pregnancy outcomes...

Ultrasonography is a common component of prenatal care worldwide and is often used in early pregnancy to determine gestational age, number of fetuses, fetal cardiac activity, and placental location. Patients and their families may also consider ultrasonography a social event, as it provides confirmation and reassurance of a normal pregnancy. Ultrasound screening is typically scheduled in the second trimester to visualize fetal anatomy and confirm gestational age. Most ultrasound examinations are reassuring, but some incidentally identify structural anomalies and soft markers for aneuploidy, making it necessary for health care providers to correctly interpret these findings...

The objective was to evaluate the effect of injectable progesterone previous to the timed artificial insemination (TAI) protocol on follicular growth, ovulation and pregnancy rate of suckled Bos indicus cows. In experiment 1, 10 days before the beginning to TAI protocol (D-10), 431 suckled-anestrus Nelore cows (249 multiparous and 182 primiparous), were allocated to one of three treatments groups (control, P4i and P4iGnRH). At this moment, cows in the P4i and P4iGnRH group received 150 mg of injectable progesterone intramuscularly (Sincrogest injetável® , Ouro Fino, Brazil)...

Stem cell transplantation has been considered a promising therapeutic approach for premature ovarian failure (POF). However, to date, no quantitative data analysis of stem cell therapy for POF has been performed. Therefore, the present study performed a meta-analysis to assess the efficacy of stem cell transplantation in improving ovarian function in animal models of POF. In addition, a case report of a patient with POF subjected to stem cell treatment was included to demonstrate that stem cell therapy also contributes to the recovery of ovarian function in patients...

Beckwith Wiedemann syndrome is a complex developmental disorder characterized by somatic overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycemia, and predisposition to embryonal tumors. We present epidemiological and clinical aspects of patients with Beckwith Wiedemann syndrome diagnosed prenatally or in the early years of life, using data from EUROCAT (European Surveillance of Congenital Anomalies) registries. The study population consisted of 371 cases identified between January 1990 and December 2015 in 34 registries from 16 European countries...

In 2004 the Danish National Board of Health changed its screening recommendations. Since 2005 a first trimester screening for Down syndrome and a prenatal ultrasound screening for congenital anomalies in the second trimester of pregnancy has been offered to all pregnant women. The aim of this study was to describe the prevalence of cleft lip with or without cleft palate and cleft palate in a Danish area and to describe associated anomalies and the development in prenatal diagnosis over time. The study was based on data from the EUROCAT Registry for Funen County...

INTRODUCTION: Pyruvate dehydrogenase deficiency (PDHD) and pyruvate carboxylase deficiency (PCD) are diseases with severe neonatal forms, and their low prevalence makes them difficult to diagnose during pregnancy. Our objective was to describe prenatal ultrasound features that may be suggestive of these diagnoses. METHODS: We analyzed 3 cases from our institution and reviewed 12 published cases of PDHD and 6 cases of PCD, recording all of the ultrasound signs, as well as magnetic resonance (MR) findings when available...

INTRODUCTION: Despite adequate glycemic control, the risks of fetal macrosomia and perinatal complications are increased in diabetic pregnancies. Adjustments of the umbilical venous (UV) distribution, including increased ductus venosus (DV) shunting, can be important fetal compensatory mechanisms, but the impact of pregestational diabetes on UV and DV flow is not known. MATERIAL AND METHODS: In this prospective study, 49 women with pregestational diabetes mellitus underwent monthly ultrasound examinations from gestational week 20 to 36...

BACKGROUND: Ectopic pregnancy (EP) is a serious complication of early pregnancy. In low-income countries diagnosis of EP is difficult and it is a major contributor to maternal mortality. We aimed to assess and improve the diagnostic process of women with EP. METHODS: We conducted a retrospective medical records study of all women with confirmed EP in Ndala Hospital from 2010 to 2012. We used data on demographics, symptoms, diagnostic procedures, surgical findings, treatment and post-operative status...

The prevalence of excess gestational weight gain is increasing worldwide and is associated with pregnancy complications, including gestational diabetes mellitus, pre-eclampsia, preterm birth, macrosomia, and development of obesity in offspring. Whereas gestational weight gain positively correlates with the gain in fat mass (FM), fat-free mass (FFM) gain is relatively consistent across pregnancies. Commonly used methods to assess body composition include anthropometry, densitometry (air displacement plethysmography, underwater weighing), and hydrometry (isotope dilution, bioimpedance analysis)...
