Are pilots prepared for a cyber-attack? A human factors approach to the experimental evaluation of pilots' behavior

The increasing prevalence of technology in modern airliners brings not just advantages, but also the potential for cyber threats. Fortunately, there have been no significant attacks on civil aircraft to date, which allows the handling of these emerging threats to be approached proactively. Although an ample body of research into technical defense strategies exists, current research neglects to take the human operator into account. In this study, we present an exploratory experiment focusing on pilots confronted with a cyber-attack. Results show that the occurrence of an attack affects all dependent variables: pilots' workload, trust, eye-movements, and behavior. Pilots experiencing an attack report heavier workload and weakened trust in the system than pilots whose aircraft is not under attack. Further, pilots who experienced an attack monitored basic flying instruments less and their performance deteriorated. A warning about a potential attack seems to moderate several of those effects. Our analysis prompts us to recommend incorporating cyber-awareness into pilots' recurrent training; we also argue that one has to consider all affected personnel when designing such training. Future research should target the development of appropriate procedures and training techniques to prepare pilots to correctly identify and respond to cyber-attacks

A picture of medically assisted reproduction activities during the COVID-19 pandemic in Europe

STUDY QUESTION: How did coronavirus disease 2019 (COVID-19) impact on medically assisted reproduction (MAR) services in Europe during the COVID-19 pandemic (March to May 2020)? SUMMARY ANSWER: MAR services, and hence treatments for infertile couples, were stopped in most European countries for a mean of 7 weeks. WHAT IS KNOWN ALREADY: With the outbreak of COVID-19 in Europe, non-urgent medical care was reduced by local authorities to preserve health resources and maintain social distancing. Furthermore, ESHRE and other societies recommended to postpone ART pregnancies as of 14 March 2020. STUDY DESIGN, SIZE, DURATION: A structured questionnaire was distributed in April among the ESHRE Committee of National Representatives, followed by further information collection through email. PARTICIPANTS/MATERIALS, SETTING, METHODS: The information was collected through the questionnaire and afterwards summarised and aligned with data from the European Centre for Disease Control on the number of COVID-19 cases per country. MAIN RESULTS AND THE ROLE OF CHANCE: By aligning the data for each country with respective epidemiological data, we show a large variation in the time and the phase in the epidemic in the curve when MAR/ART treatments were suspended and restarted. Similarly, the duration of interruption varied. Fertility preservation treatments and patient supportive care for patients remained available during the pandemic. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: Data collection was prone to misinterpretation of the questions and replies, and required further follow-up to check the accuracy. Some representatives reported that they, themselves, were not always aware of the situation throughout the country or reported difficulties with providing single generalised replies, for instance when there were regional differences within their country. WIDER IMPLICATIONS OF THE FINDINGS: The current article provides a basis for further research of the different strategies developed in response to the COVID-19 crisis. Such conclusions will be invaluable for health authorities and healthcare professionals with respect to future similar situations.peer-reviewe

ESHRE PGT Consortium good practice recommendations for the detection of structural and numerical chromosomal aberrations

The field of preimplantation genetic testing (PGT) is evolving fast, and best practice advice is essential for regulation and standardisation of diagnostic testing. The previous ESHRE guidelines on best practice for PGD, published in 2005 and 2011, are considered outdated, and the development of new papers outlining recommendations for good practice in PGT was necessary. The current paper provides recommendations on the technical aspects of PGT for chromosomal structural rearrangements (PGT-SR) and PGT for aneuploidies (PGT-A) and covers recommendations on array-based comparative genomic hybridisation (aCGH) and next-generation sequencing (NGS) for PGT-SR and PGT-A and on fluorescence in situ hybridisation (FISH) and single nucleotide polymorphism (SNP) array for PGT-SR, including laboratory issues, work practice controls, pre-examination validation, preclinical work-up, risk assessment and limitations. Furthermore, some general recommendations on PGT-SR/PGT-A are formulated around training and general risk assessment, and the examination and post-examination process. This paper is one of a series of four papers on good practice recommendations on PGT. The other papers cover the organisation of a PGT centre, embryo biopsy and tubing and the technical aspects of PGT for monogenic/single-gene defects (PGT-M). Together, these papers should assist everyone interested in PGT in developing the best laboratory and clinical practice possible
