Background: Students with intellectual and developmental disabilities (IDD) were disproportionately impacted by the COVID‐19 pandemic. This study's goal was to assess the effectiveness of 2 messaging strategies on participation in SARS‐CoV‐2 weekly testing. Methods: Cluster randomized trials were conducted at 2 school systems, the special school district (SSD) and Kennedy Krieger Institute (Kennedy) to assess messaging strategies, general versus enhanced, to increase weekly screening for SARS‐CoV‐2. Testing was offered to staff and students from November 23, 2020 to May 26, 2022. The primary outcomes were percentage of students and staff consented weekly and percentage of study participants who had a test performed weekly. Generalized estimating equation models were utilized to evaluate the primary outcomes. Results: Increases in enrollment and testing occurred during study start up, the beginning of school years, and following surges in both systems. No statistical difference was observed in the primary outcomes between schools receiving standard versus enhanced messaging. Implications for School Health Policy, Practice, and Equity: Frequent and consistent communication is vital for families and staff. Weekly screening testing within schools is possible and highlighted the importance of utilizing equitable protocols to provide important testing to students with IDD. Conclusion: Enhanced messaging strategies did not increase the number of participants enrolled or the percentage of enrolled participants being tested on a weekly basis. [ABSTRACT FROM AUTHOR]

Schools provide important services that cannot be provided virtually to children with medical complexity and children with intellectual and developmental disabilities, yet these children are among the most at risk from coronavirus disease 2019 (COVID-19). To keep schools open for children with medical complexity and/or intellectual and developmental disabilities during the COVID-19 pandemic, we implemented severe acute respiratory syndrome coronavirus 2 testing at 3 sites across the United States. We evaluated testing strategies for staff and students at each site, including specimen source (nasopharyngeal or saliva), test type (polymerase chain reaction or rapid antigen), and frequency and type (screening versus exposure/symptomatic) of testing provided. Among the greatest barriers to severe acute respiratory syndrome coronavirus 2 testing in these schools was the engagement of caregivers and challenges navigating legal guardianship for consenting adult students. Additionally, variability in testing strategies nationally and in the community, as well as surges in viral transmission across the United States during the course of the pandemic, led to testing hesitancy and variable participation rates. Essential to the successful implementation of testing programs is building a trusted relationship with school administrators and guardians. Leveraging our experiences with COVID-19 and forming lasting school partnerships can help keep schools for vulnerable children safe in future pandemics. [ABSTRACT FROM AUTHOR]

The olive shells of the genus Amalda comprises readily recognized species of marine neogastropod mollusks found around the world. The New Zealand Amalda fauna has particular notoriety as providing one of the best demonstrations of evolutionary morphological stasis, a prerequisite for punctuated equilibrium theory. An excellent fossil record includes representation of three extant endemic Amalda species used to explore patterns of form change. However, the phylogenetic relationship of the New Zealand Amalda species and the timing of their lineage splitting have not been studied, even though these would provide valuable evidence to test predictions of punctuated equilibrium. Here, we use entire mitogenome and long nuclear rRNA gene cassette data from 11 Amalda species, selected from New Zealand and around the world in light of high rates of endemicity among extant and fossil Amalda. Our inferred phylogenies do not refute the hypothesis that New Zealand Amalda are a natural monophyletic group and therefore an appropriate example of morphological stasis. Furthermore, estimates of the timing of cladogenesis from the molecular data for the New Zealand group are compatible with the fossil record for extant species and consistent with expectations of punctuated equilibrium.
