Automated three-dimensional ultrasound imaging using artificial intelligence can reliably identify and measure fetal biparietal diameter and head circumference, but is less consistent in accurately identifying and measuring transcerebellar diameter, cisterna magna and posterior horn of the lateral ventricle.
What are the clinical implications of this work?Further optimization of this automated ultrasound imaging technology for fetal head biometry based on machine learning is necessary prior to incorporation into routine sonographic protocols.
ImportanceWhile COVID-19 vaccines are highly effective against disease, breakthrough infections may occur in the context of rising variants of concern.ObjectiveWe paired random and passive surveillance nucleic acid testing with analysis of viral whole genomic sequences to detect and describe breakthrough infections, focusing in a university community.DesignAnterior nasal swabs were collected from individuals for a nucleic acid amplification test (NAAT) for detection of SARS-CoV-2. A subset of NAAT positive samples was sequenced to determine variants associated with infections. Included in the testing and sequencing protocol were individuals that were fully vaccinated.SettingThis study was performed as part of a surveillance program for SARS-CoV-2 on a university campus with 49,700 students and employees.ParticipantsSurveillance testing was random and included approximately 10% of the population each week. Additionally, individuals self-identified with COVID-19 related symptoms or those that had close contact with SARS-CoV-2 positive individuals were also tested.
