Objective: To evaluate the impact of preimplantation genetic testing for aneuploidy (PGT-A) on first transfer live birth rate (LBR) and cumulative LBR (CLBR) in donor oocyte in vitro fertilization (IVF) cycles.
Design: Retrospective cohort study of the Society for Assisted Reproductive Technology Clinic Outcome Reporting System database.
Setting: Fertility centers reporting to Society for Assisted Reproductive Technology.
Objective: To determine whether body mass index (BMI) was associated with live birth in patients undergoing transfer of frozen-thawed preimplantation genetic testing for aneuploidy (PGT-A) embryos.
Design: Retrospective cohort study of cycles reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System.
Subjects: All autologous and donor recipient PGT-A-tested cycles reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System from 2014 to 2017.
Article Synopsis
- - The study evaluates the training quality of residents at the Sverzhevky Research Clinical Institute of Otorhinolaryngology using a questionnaire to gather feedback from second-year residents.
- - Results show high satisfaction among residents regarding their training, effective use of electronic resources, strong lecture quality, and a desire for enhanced surgical training.
- - The findings help inform improvements in the educational process and support the development of residents’ professional competencies and readiness for independent practice.
In search of a more effective process of ethane oxidative hydrogenation, different operation modes (thermal and microwave heating) are compared. The catalyst Mo-V-Te-Nb-O was prepared by hydrothermal synthesis and characterized by a set of physicochemical methods (XRD, N adsorption, SEM, EDX). The direct microwave heating of the catalyst layer is proposed as an alternative way of energy-saving ethane-to-ethylene oxidation by a Mo-V-Te-Nb-O system.

Methods: Retrospective cohort study of the SART CORS database, comparing CLBR for patients using autologous oocytes, with or without PGT-A. The first reported autologous ovarian stimulation cycle per patient between January 1, 2014, and December 31, 2015, and all linked embryo transfer cycles between January 1, 2014, and December 31, 2016, were included in the study.
