Assessment of artificial intelligence model and manual morphokinetic annotation system as embryo grading methods for successful live birth prediction: a retrospective monocentric study.

Purpose: The introduction of the time-lapse monitoring system (TMS) and the development of predictive algorithms could contribute to the optimal embryos selection for transfer. Therefore, the present study aims at investigating the efficiency of KIDScore and iDAScore systems for blastocyst stage embryos in predicting live birth events.

Methods: The present retrospective study was conducted in a private IVF Unit setting throughout a 10-month period from October 2021 to July 2022, and included the analysis of 429 embryos deriving from 91 IVF/ICSI cycles conducted due to infertility of various etiologies.

Male Age and Progressive Sperm Motility Are Critical Factors Affecting Embryological and Clinical Outcomes in Oocyte Donor ICSI Cycles.

This retrospective cohort study aimed to explore whether paternal age and semen quality parameters affect the embryological and clinical outcomes of ICSI with oocyte donation. A total of 339 oocyte donation (OD)-ICSI cycles were categorized into four groups according to the semen parameter profiles of the male counterparts: normozoospermia (NS, n = 184), oligozoospermia (OS, n = 41), asthenozoospermia (AS, n = 50), and oligoasthenozoospermia (OAS, n = 64). The effect of age, total sperm count, and progressive motility was separately analyzed for reproductive outcomes and compared between the study groups: fertilization, blastulation, and top-quality embryo rate, biochemical and clinical pregnancy, live birth, and miscarriage.

Review of the Literature on Leiomyoma and Leiomyosarcoma of the Adrenal Gland: A Systematic Analysis of Case Reports.

Background/aim: To date few cases of smooth muscle-derived tumors of the adrenal gland have been reported and their treatment remains a medical challenge. The aim of this manuscript was to systematically review the literature and present the tumor characteristics and their management in order to provide a standardized approach to their diagnosis and management.

Materials And Methods: We searched five databases (PubMed, Scopus, Elsevier, ResearchGate, Google scholar) for relevant articles published until March 2020.

Primary adrenal leiomyosarcoma: A case report.

Adrenal leiomyosarcomas are rare mesenchymal tumors of the suprarenal region that are usually diagnosed after they have reached a large size. We report the case of a 62-year-old male with an incidentally found left adrenal mass. Magnetic resonance imaging of the retroperitoneal space showed a heterogeneously enhanced mass, measuring 10x8.

Student Disaffection: The Contribution of Greek In-service Kindergarten Teachers in Engaging Each Preschooler in Learning.

Engaging each student in learning comprises a continuous challenge and concern for the contemporary teacher. Educational research confirms the alarming increase of the disengaged students, relating student disaffection to adverse effects on students' academic development. In the present research through one-on-one, semi-structured interviews, we investigate 80 Greek in-service kindergarten teachers' opinions with regards to the significance of engaging the disengaged students in learning activities in preschool environments.

Teachers' Views on the Participation of Parents in the Transition of their Children from Kindergarten to Primary School.

Internationally, a great number of researchers have pointed out the significance of school-family relationship in the process of children's transition to primary schools. However, only recently has it been a subject of research in Greece. The purpose of this particular research, which has a sample of 1602 pre-primary and primary school teachers, is to investigate teachers' viewpoints on the role of parents in the process of their children's transition to primary school.

The impact of HCG in IVF Treatment: Does it depend on age or on protocol?

Objective: to evaluate the effect of the addition of low dose human chorionic gonadotropin (hCG) to human menopausal gonadotropin (HMG) throughout the early follicular phase in controlled ovarian stimulation (COS) conducted with two difference regimens. Gonadotropin-releasing hormone (GnRH) antagonist and short GnRH-agonist protocol were applied in two in vitro fertilization (IVF) clinics.

Methods: Clinical study conducted during the period 2014-2016 in two IVF clinics in a cohort of 240 women.

Intravenous infusion of PAF affects ovulation, fertilization and preimplantation embryonic development in NZB x NZW F1 hybrid mice.

Platelet Activating Factor (PAF) is a bioactive phospholipid, which exhibits a variety of biological activities and plays a significant role in all aspects of reproduction. In this work, a single intravenous injection of various concentrations of PAF shortly after Human Chorionic Gonadotropin (HCG) administration as well as 24 and 48 h before HCG administration was studied in NZB x NZW F1 hybrid mice. Optimum results were observed when PAF was injected just after the administration of HCG.
