Rescuing monopronucleated-derived human blastocysts: a model to study chromosomal topography and fingerprinting.

Objective: To quantify the percentage of monopronuclear-derived blastocysts (MNBs) that are potentially useful for reproductive purposes using classic and state-of-the-art chromosome analysis approaches, and to study chromosomal distribution in the inner cell mass (ICM) and trophectoderm (TE) for intertissue/intratissue concordance comparison.

Design: Prospective experimental study.

Setting: Single-center in vitro fertilization clinic and reproductive genetics laboratory.

Reproducibility and Reliability of the Quality of Life Questionnaire in Patients With Atrial Fibrillation.

Background: Studies have shown the impact of atrial fibrillation (AF) on the patients' quality of life. Specific questionnaires enable the evaluation of relevant events. We previously developed a questionnaire to assess the quality of life of patients with AF (AFQLQ version 1), which was reviewed in this study, and new domains were added.
