Electronic Health Records at People's Hands Across Europe: The InteropEHRate Protocols.

Sharing of personal health data could facilitate and enhance the quality of care and the conduction of further research studies. However, these data are still underutilized due to legal, technical, and interoperability challenges, whereas the data subjects are not able to manage, interact, and decide on what to share, with whom, and for what purposes. This barrier obstacles continuity of care across in the European Union (EU), and neither healthcare providers nor data researchers nor the citizens are benefiting through efficient healthcare treatment and research.

MFGE8 regulates TGF-β-induced epithelial mesenchymal transition in endometrial epithelial cells in vitro.

This study investigated the role of milk fat globule-epidermal growth factor-factor 8 (MFGE8) in TGF-β-induced epithelial-mesenchymal transition (EMT) of endometrial epithelial cells. These were in vitro studies using human endometrial epithelial cells and mouse blastocysts. We investigated the ability of TGF-β to induce EMT in endometrial epithelial cells (HEC-1A) by assessment of cytological phenotype (by light and atomic force microscopy), changes in expression of the markers of cell adhesion/differentiation E- and N-cadherin, and of the transcription factor Snail (by immunofluorescence and immunoblotting), and competence to support embryo attachment in a mouse blastocyst outgrowth assay.

ICSI outcomes in men undergoing TESE for azoospermia and impact of maternal age.

This retrospective study compared clinical outcomes in men with obstructive and nonobstructive azoospermia after ICSI following testicular sperm extraction and the influence of maternal age. Fertilisation rates, embryo quality, pregnancy rates, miscarriage rates and live birth rates were evaluated. Men with obstructive azoospermia (OA) had significantly higher rates of diploid fertilisation and clinical pregnancy than men with nonobstructive azoospermia (NOA), but miscarriage rates and live birth rates were not significantly different.

Transcriptome of early embryonic invasion at implantation sites in a murine model.

Successful implantation relies on the interaction between a competent embryo and a receptive endometrium. The aim of the present study was to investigate genes differentially expressed in early invasive embryonic tissue versus decidual tissue in mice. Samples were obtained from the ectoplacental cone, the immediately surrounding deciduas and from deciduas from interimplantation sites.

Sex steroids regulate epithelial-stromal cell cross talk and trophoblast attachment invasion in a three-dimensional human endometrial culture system.

Human embryo implantation involves a complex network of molecular signaling that is modulated by endocrine and paracrine pathways. Here, we performed studies using a unique and recently developed three-dimensional (3D) implantation model, characterized by an endometrium-like 3D culture system and Jar cell-derived spheroids mimicking the embryo/trophoblast. The aims were to investigate the effects of 17β estradiol (E2) and medroxyprogesterone acetate (MPA) on (1) the interaction between epithelial and stromal cells, and (2) the attachment and invasion of trophoblast cells.

Modulation of the expression of the transcription factors T-bet and GATA-3 in immortalized human endometrial stromal cells (HESCs) by sex steroid hormones and cAMP.

T-bet and GATA-3 are known to regulate cytokine expression in T lymphocytes, and cytokines have been implicated in endometrial regulation and implantation. Previous work showed that female steroid hormones modulate the expression of T-bet in endometrial epithelial cells, suggesting a mechanism for local immune regulation in the human endometrium. We hypothesized that stromal cells are involved in immune regulation, as they have been shown to exert paracrine effects on other endometrial cells and compartments and also secrete cytokines.

The search for biomarkers of human embryo developmental potential in IVF: a comprehensive proteomic approach.

The objective of these studies was to identify differentially expressed peptides/proteins in the culture media of embryos grown during in vitro fertilization (IVF) treatment to establish their value as biomarkers predictive of implantation potential and live birth. Micro-droplets of embryo culture media from IVF patients (conditioned) and control media maintained under identical culture conditions were collected and frozen at -80°C on Days 2-3 of in vitro development prior to analysis. The embryos were transferred on Day 3.

Epithelial cell protein milk fat globule-epidermal growth factor 8 and human chorionic gonadotropin regulate stromal cell apoptosis in the human endometrium.

Objective: To study the regulation of apoptosis in human endometrial cells. The specific aims were to determine whether milk fat globule-epidermal growth factor 8 (MFG-E8), a novel endometrial epithelial protein, modulates caspase activation and DNA fragmentation; and to examine whether hCG, an early embryonic product, regulates Bax and Bcl-2 equilibrium, as well as MFG-E8 expression.

Design: Primary cultures of human endometrial epithelial cells (EECs) and endometrial stromal cells (ESCs).

Milk fat globule epidermal growth factor 8 (MFG-E8): a novel protein in the mammalian endometrium with putative roles in implantation and placentation.

Objectives: MFG-E8 is a novel endometrial protein with conserved functions in tissue remodeling and angiogenesis in non-uterine tissues. Our aims were: 1. To examine the presence of MFG-E8 protein in the human endometrium during the window of implantation, in human endometrial cell lines, in human placental tissue at different gestational ages, and in murine implantation sites during early gestation; and 2.

Does the degree of hypothalamic-pituitary-ovarian recovery after oral contraceptive pills affect outcomes of IVF/ICSI cycles receiving GnRH-antagonist adjuvant therapy in women over 35 years of age?

Purpose: To evaluate if the degree of recovery of serum gonadotropins after oral contraceptive pills (OCP) pretreatment has an impact on ovarian response in GnRH-antagonist IVF cycles in women of advanced maternal age.

Methods: In this retrospective cohort study, we included 98 women 35-42 years undergoing their first IVF cycle receiving gonadotropins and a fixed GnRH-antagonist adjuvant protocol. Data analysis was carried out according to changes in serum FSH, LH and estradiol (E(2)) levels (basal and post-OCP) divided in quartiles, and also according to absolute levels.

The -346T polymorphism of the SH2D1A gene is a risk factor for development of autoimmunity/lymphoproliferation in males with defective Fas function.

Inherited defects decreasing function of the Fas death receptor cause autoimmune lymphoproliferative syndrome (ALPS) and its variant Dianzani autoimmune lymphoproliferative disease (DALD). Since a deleterious mutation of the SH2D1A gene protects MRLlpr/lpr mice from ALPS development, we investigated the role of SH2D1A, located in the X chromosome, in 51 patients with ALPS or DALD by mutational screening of coding and regulative sequences. Allelic frequency of the -346C>T polymorphism was different in male patients and controls (-346T: 61% vs 36%, p = 0.

Objectives: We conducted a prospective blinded study to evaluate the costs, accuracy, risks, and benefits of 3-dimensional (3D) transvaginal sonography compared to hysterosalpingography.

Methods: A total of 101 women aged 26 to 44 years with evidence of uterine anomalies were enrolled. All participants had routine hysterosalpingography as part of their infertility evaluation as well as 3D transvaginal sonography as part of the study.

A novel model of human implantation: 3D endometrium-like culture system to study attachment of human trophoblast (Jar) cell spheroids.

There is an urgent need to develop optimized experimental models to examine human implantation. These studies aimed to (i) establish a human endometrium-like three-dimensional (3D) culture system, and (ii) examine the attachment of trophoblast-like Jar spheroids to the culture. In the present work, 3D endometrial cultures were constructed with fibrin-agarose as matrix scaffold, and using epithelial and stromal cells from both human primary cultures and established cell lines.
