To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.

This paper calculates developmental index of language growth in Egyptian Arabic based on a corpus consists of spontaneous speech samples from10 children 5 boys and 5 girls from 1.7 to 4 years. Depending on 30 minutes transcripts of spontaneous speech production the following properties of collected data were analysed: size of vocabulary and frequency of word use in relation to age (development of types and tokens) and individual differences in vocabulary size. The contribution of the current study lies in the use of vocabulary profile results as a measure of potential indicators of developmental language delay. The results provide a new measurement tool for lexical growth at different developmental stages.

Purpose: This article describes a framework for developing international research collaborations among graduate students. Central to this framework is the utility of institutional and association-based academic mentorship programs in developing collaborative partnerships. We illustrate how the American Speech-Language-Hearing Association's Mentoring Academic Research Careers program served as a vehicle for fostering remote collaboration and provided training experiences for graduate students during the COVID-19 pandemic. Conclusions: This model successfully supported doctoral students in developing an ongoing and sustainable research partnership during a challenging time when in-person networking opportunities were unavailable. This partnership provided a unique pathway for professional development that complemented formal academic training. More broadly, international collaboration experiences such as these provide valuable, skill-based training for all students, such that they are better equipped to serve diverse populations and as members of diverse teams. We offer recommendations for others endeavoring to develop international collaboration initiatives for students paired with mentorship.
