#1
Gerhard B Theron
The free-flow pressure controlled uterine balloon (Ellavi UBT; Sinapi biomedical, Stellenbosch, South Africa) allows the expulsion of water from the balloon to reduce volume and pressure control by adjusting the height of the supply bag above the patient. The balloon can be filled to a capacity of 750 mL without requiring expansion pressure. The device is affordable for use in lesser resourced countries with a sales price from the factory of approximately US $6. This article is protected by copyright. All rights reserved...

BACKGROUND: The development of models that incorporate intact microvascular networks enables the investigation of multicellular dynamics during angiogenesis. Our laboratory introduced the rat mesentery culture model as such a tool, which would be enhanced with mouse tissue. Since mouse mesentery is avascular, an alternative is mouse mesometrium, the connective tissue of uterine horns. The study's objective was to demonstrate that mouse mesometrium contains microvascular networks that can be cultured to investigate multicellular dynamics during angiogenesis...

Collision tumours of the uterine cervix are extremely uncommon with exact incidence not known. Unlike squamous cell carcinoma (SCC) and adenocarcinoma that are known to coexist, small cell neuroendocrine carcinoma (SCNEC) is rarely documented with other histological types in the cervix. We report such rare case of a collision tumour in cervix displaying dual histological component of SCNEC and SCC in a 36-year-old woman. The case is being presented because of its rarity and represents a unique and hitherto seldom-reported combination of two malignant tumours with distinct and often contrasting epidemiology, histology and prognosis coexisting in the same patient...

The importance of apolipoprotein E genotypes and allelic polymorphisms in the etiology of recurrent miscarriage is controversial. We plan to investigate this in a two-group study involving more than a thousand participants. In total, 1046 subjects (802 participants in the first group, 244 participants in the second group) were investigated. Women in the first group had a history of ≥3 consecutive spontaneous miscarriage and women in the second group had at most one miscarriage in three consecutive pregnancies...

The aim of the present study was to investigate the effects of a strategy for extending pro-oestrus (the interval between luteolysis and ovulation) in an oestrus synchronisation protocol (named J-Synch) in beef heifers on follicular growth, sexual steroid concentrations, the oestrogen receptor ERα and progesterone receptors (PR) in the uterus, insulin-like growth factor (IGF) 1 and pregnancy rates. In Experiment 1, heifers treated with the new J-Synch protocol had a longer pro-oestrus period than those treated with the conventional protocol (mean (±s...

Maternal exposure to tobacco and alcohol is a known cause, among others, for fetal growth restriction (FGR). Clinically, FGR can be subclassified into two forms: intrauterine growth restriction (IUGR) and small for gestational age (SGA), based on the severity of the growth retardation, and abnormal uterine artery Doppler or cerebro-placental ratio. This study aimed at investigating any differential correlation between maternal exposures to these toxins with the two clinical forms of FGR. Therefore, a case-control study was conducted in Barcelona, Spain...

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...

Preterm birth is the major challenge in obstetrics affecting ~10% of pregnancies. Pan-prostaglandin synthesis inhibitors (NSAID) prevent preterm labor and prolong pregnancy but raise concerns about fetal renal and cardiovascular safety. We conducted preclinical studies examining the tocolytic effect and fetal safety of the oral prodrug candidate OBE022 and its parent OBE002, both potent and highly selective antagonist of the contractile PGF2α prostaglandin receptor (FP). Efficacy of OBE022 and OBE002, alone and in combination with other tocolytics, was assessed in human tissues and pregnant animal models for inhibition of uterine contraction and delay of parturition...

In this study differences in the placental microbiota of term and preterm deliveries from a large UK pregnancy cohort were studied using 16S targeted amplicon sequencing. The impact of contamination from DNA extraction, PCR reagents, as well as those from delivery itself were also examined. A total of 400 placental samples from 256 singleton pregnancies were analysed and differences investigated between spontaneous preterm, non-spontaneous preterm, and term delivered placenta. DNA from recently delivered placenta was extracted, and screening for bacterial DNA was carried out using targeted sequencing of the 16S rRNA gene on the Illumina MiSeq platform...

Bacterial contamination of the uterus following calving is ubiquitous in the dairy cow, 40% of cows develop postpartum uterine infection, including metritis. While predisposing factors like twinning and dystocia are associated with metritis, it is unclear why some cows remain healthy following calving and others develop uterine infection, negatively impacting animal health, milk production and economic return. Here, we profiled peripheral blood mononuclear cells of cows before calving and during postpartum metritis...

Thirty-eight percent of US adult women are obese, meaning that more children are now born of overweight and obese mothers, leading to an increase in predisposition to several adult onset diseases. To explore this phenomenon, we developed a maternal obesity animal model by feeding mice a diet composed of high fat/ high sugar (HF/HS) and assessed both maternal diet and offspring diet on the development of endometrial cancer (ECa). We show that maternal diet by itself did not lead to ECa initiation in wildtype offspring of the C57Bl/6J mouse strain...

Although expansive remodeling of the maternal uterine circulation during pregnancy is essential for maintaining uteroplacental perfusion and normal fetal growth, the underlying physiological mechanisms are not well understood. Using a rat model, surgical approaches were used to alter uterine hemodynamics and wall shear stress (WSS) in order to evaluate the effects of WSS and venoarterial communication (e.g. transfer of placentally derived growth signals from post-placental veins to pre-placental arteries) on gestational uterine vascular remodeling...

BACKGROUND: Pregnancy is accompanied by profound changes in lipid metabolism. We aimed to assess whether effects of second trimester body mass index and maternal lipid concentrations are associated with an increased risk of adverse pregnancy outcomes. METHODS: We investigated the serum levels of maternal lipids during the second trimester in pregnancy, and analyzed associations between the lipid levels and the risk of adverse pregnancy outcome. Seven hundred and seventy-four pregnant women were enrolled in this study between February 2016 and June 2016...

Metastatic nodal involvement is a critical prognostic factor in uterine cervical cancer (UCC). To improve current methods of detecting UCC metastases in lymph nodes (LNs), we used quantitative PCR (qPCR) to assess mRNA expression of potential metastatic biomarkers. We found that expression of HPV16-E6, cytokeratin19 (CK19), and mucin1 (MUC1) is consistently upregulated in tumors and metastatic tissues, supporting a role for these genes in UCC progression. These putative biomarkers were able to predict the presence of histologically positive metastatic LNs with respective sensitivities and specificities of 82% and 99% (CK19), 76% and 95% (HPV16-E6), and 76% and 78% (MUC1)...

Preeclampsia is the most common clinical disorder in pregnancy and might result from disordered uterine environments caused by epigenetic modifications, including deregulation of DNA methylation/demethylation. Recent research has indicated that 5-hydroxymethylcytosine (5hmC), a DNA base derived from 5-methylcytosine (5mC) via oxidation by ten-eleven translocation (TET) enzymes, is involved in DNA methylation-related plasticity. Here, we report that TET2 expression and 5hmC abundance are significantly altered in the placentas from preeclampsia patients...
