Comparison of embryologist stress, somatization, and burnout reported by embryologists working in UK HFEA-licensed ART/IVF clinics and USA ART/IVF clinics.

Study Question: What is the prevalence of occupational stress, somatization, and burnout reported by UK and US, embryologists and the impact of work conditions on these well-being outcomes?

Summary Answer: Surveyed UK and US embryologists reported moderate perceived stress, low somatic symptom severity, high levels of burnout, and overall stressful work conditions, but with differences that could be due to country-specific occupational and employment characteristics.

What Is Known Already?: Spanish, UK, US, and international surveys have identified high levels of occupational stress, somatization, burnout, and occupational health issues among embryologists. These issues have been attributed to embryologists' occupational challenges and work conditions.

The Internet of Things in assisted reproduction.

The Internet of Things (IoT) is a network connecting physical objects with sensors, software and internet connectivity for data exchange. Integrating the IoT with medical devices shows promise in healthcare, particularly in IVF laboratories. By leveraging telecommunications, cybersecurity, data management and intelligent systems, the IoT can enable a data-driven laboratory with automation, improved conditions, personalized treatment and efficient workflows.

Cryostorage management of reproductive cells and tissues in ART: status, needs, opportunities and potential new challenges.

Among the wide range of procedures performed by clinical embryologists, the cryopreservation of reproductive cells and tissues represents a fundamental task in the daily routine. Indeed, cryopreservation procedures can be considered a subspecialty of medically assisted reproductive technology (ART), having the same relevance as sperm injection or embryo biopsy for preimplantation genetic testing. However, although a great deal of care has been devoted to optimizing cryopreservation protocols, the same energy has only recently been spent on developing and implementing strategies for the safe and reliable storage and transport of reproductive specimens.

The in vitro fertilization laboratory: teamwork and teaming.

Delivery of fertility treatment involves both teamwork within a discipline as well as teaming across multiple work areas, such as nursing, administrative, laboratory, and clinical. In contrast to small autonomous centers, the in vitro fertilization (IVF) laboratory team in large clinics must function both as a team with many members and a constellation of teams to deliver seamless, safe, and effective patient-centered care. Although this review primarily focuses on teamwork within the IVF laboratory, which comprises clinical laboratory scientists and embryologists who perform both diagnostic and therapeutic procedures, it also discusses the laboratory's wider role with other teams of the IVF clinic, and the role of teaming (the ad hoc creation of multidisciplinary teams) to function highly and address critical issues.

Vitrifying multiple embryos in different arrangements does not alter the cooling rate.

Vitrification is the most common method of cryopreservation of gametes in fertility clinics due to its improved survival rates compared to slow freezing techniques. For the Open Cryotop® vitrification device, the number of oocytes, or embryos, mounted onto a single device can vary. In this work, a mathematical model is developed for the cooling of oocytes and embryos (samples).

Comparison of 36 assisted reproduction laboratories monitoring environmental conditions and instrument parameters using the same quality-control application.

Research Question: Assisted reproduction laboratories record instrument performance periodically. No standardized guidelines have been produced for this activity despite mandatory auditing systems in several countries. This study of 36 laboratories in 12 different countries was conducted to assess differences and similarities between quality assurance programmes using an adaptable cloud-based quality-control app for instrument monitoring.

Morphokinetic parameters of early embryo development via time lapse monitoring and their effect on embryo selection and ICSI outcomes: a prospective cohort study.

Purpose: To compare the outcomes of embryos selected via time lapse monitoring (TLM) versus those selected with conventional methods of selection in subfertile women undergoing ICSI.

Methods: The study population (239 women) was classified into two groups, based on the monitoring method used: Group 1 (TLM) and Group 2 (conventional monitoring). Groups were compared according to the clinical and ICSI cycle characteristics and reproductive outcomes, while transfers were performed at day 2 or 3.

Real-time PCR for single-cell genotyping in sickle cell and thalassemia syndromes as a rapid, accurate, reliable, and widely applicable protocol for preimplantation genetic diagnosis.

Sickle-cell and beta-thalassemia syndromes are priority genetic diseases for prevention programs involving population screening with the option of prenatal diagnosis for carrier couples. Preimplantation genetic diagnosis (PGD) represents a specialized alternative to prenatal diagnosis and is most appropriately used for couples with an unsuccessful reproductive history and/or undergoing assisted reproduction. However, clinical application of PGD has been hindered by difficulties in reliably transferring molecular diagnostic protocols to the single-cell level.

An evaluation of PGD in clinical genetic services through 3 years application for prevention of beta-thalassaemia major and sickle cell thalassaemia.

PGD represents an alternative within prenatal diagnosis services, which avoids terminating affected on-going pregnancies. In Greece, prevention programmes for haemoglobinopathies, including the option of prenatal diagnosis, are well established. Following optimization of a single-cell genotyping strategy (designed to be applicable for the majority of beta-thalassaemia major or sickle thalassaemia genotype interactions) along with close collaboration with an IVF unit, we integrated the option of PGD for at-risk couples with a problematic reproductive history.

Multiplex sequence variation detection throughout the CFTR gene appropriate for preimplantation genetic diagnosis in populations with heterogeneity of cystic fibrosis mutations.

Cystic fibrosis (CF) is one of the most important genetic diseases requiring prevention programmes. Preimplantation genetic diagnosis (PGD) represents an alternative to prenatal diagnosis, and is especially appropriate for couples with an unsuccessful reproductive history. For clinical application, protocols must be optimized to minimize PCR failure, allelic drop-out (ADO) and contamination, while simultaneously detecting a wide spectrum of CF genotypes.
