    Abstract As hospitals have experienced a surge of Covid-19 patients, investigators of Covid-19 treatment trials face a difficult problem: when an institution has more eligible and interested patients than trial slots, who should be enrolled? Defining a clear strategy for selecting participants for "high-demand" Covid-19 treatment trials is important to avoid ad hoc and potentially biased decision-making by local investigators, which could inadvertently compromise a trial's social value, participants' interests, or fairness. In this article, we propose a set of ethical criteria for evaluating participant-selection strategies for such trials. We argue that the pandemic context-in particular, great urgency to develop safe and effective treatments, uncertainty surrounding Covid-19, and strain on the health care system that limits the time and effort available for trial enrollment-favors participant-selection strategies that optimize the ease of enrollment and, ideally, social value. A lottery and, where possible, a weighted lottery have important advantages in these respects.

    Abstract Isotope effects have received increasing attention in materials science and engineering because altering isotopes directly affects phonons, which can affect both thermal properties and optoelectronic properties of conventional semiconductors. However, how isotopic mass affects the optoelectronic properties in 2D semiconductors remains unclear because of measurement uncertainties resulting from sample heterogeneities. Here, we report an anomalous optical bandgap energy red shift of 13 (±7) milli-electron volts as mass of Mo isotopes is increased in laterally structured

    Abstract Purpose: Advances in gene therapy and precision medicine have led to a growing number of novel treatments for rare genetic diseases. Patients/families may lack access to up-to-date, accurate, and relevant information about these treatments. Social media offers one potentially important resource for these communities. Our goal was to understand how patients/families with spinal muscular atrophy (SMA)-a rare genetic condition-used social media to share, consume, and evaluate information about the novel treatment nusinersen (Spinraza) following the drug's approval.
    Methods: We conducted qualitative, semistructured interviews with 20 SMA patients or parents of patients, deriving themes and subthemes through content and thematic network analysis. Participants also completed a demographic survey.
    Results: Participants described leveraging social media to learn about nusinersen treatment, make informed treatment decisions, and advocate for/access treatment. They also described critically evaluating the trustworthiness of nusinersen-related information on social media and the privacy risks of social media use.
    Conclusion: Patients/families used social media to navigate the new and dynamic landscape of nusinersen treatment for SMA, while attempting to mitigate misinformation and privacy risks. As new treatments become available, providers and patients/families may benefit from proactively discussing social media use, so as to maximize important benefits while minimizing risks.

    Abstract Objective: Data-informed decision making is valued among school districts, but challenges remain for local health departments to provide data, especially during a pandemic. We describe the rapid planning and deployment of a school-based COVID-19 surveillance system in a metropolitan US county.
    Methods: In 2020, we used several data sources to construct disease- and school-based indicators for COVID-19 surveillance in Franklin County, an urban county in central Ohio. We collected, processed, analyzed, and visualized data in the COVID-19 Analytics and Targeted Surveillance System for Schools (CATS). CATS included web-based applications (public and secure versions), automated alerts, and weekly reports for the general public and decision makers, including school administrators, school boards, and local health departments.
    Results: We deployed a pilot version of CATS in less than 2 months (August-September 2020) and added 21 school districts in central Ohio (15 in Franklin County and 6 outside the county) into CATS during the subsequent months. Public-facing web-based applications provided parents and students with local information for data-informed decision making. We created an algorithm to enable local health departments to precisely identify school districts and school buildings at high risk of an outbreak and active SARS-CoV-2 transmission in school settings.
    Practice implications: Piloting a surveillance system with diverse school districts helps scale up to other districts. Leveraging past relationships and identifying emerging partner needs were critical to rapid and sustainable collaboration. Valuing diverse skill sets is key to rapid deployment of proactive and innovative public health practices during a global pandemic.

    Abstract Overdoses from non-medical use of opioids can lead to hypoxemic/hypercarbic respiratory failure, cardiac arrest, and death when left untreated. Opioid toxicity is readily reversed with naloxone, a competitive antagonist that can restore respiration. However, there remains a critical need for technologies to administer naloxone in the event of unwitnessed overdose events. We report a closed-loop wearable injector system that measures respiration and apneic motion associated with an opioid overdose event using a pair of on-body accelerometers, and administers naloxone subcutaneously upon detection of an apnea. Our proof-of-concept system has been evaluated in two environments: (i) an approved supervised injection facility (SIF) where people self-inject opioids under medical supervision and (ii) a hospital environment where we simulate opioid-induced apneas in healthy participants. In the SIF (n = 25), our system identified breathing rate and post-injection respiratory depression accurately when compared to a respiratory belt. In the hospital, our algorithm identified simulated apneic events and successfully injected participants with 1.2 mg of naloxone. Naloxone delivery was verified by intravenous blood draw post-injection for all participants. A closed-loop naloxone injector system has the potential to complement existing evidence-based harm reduction strategies and, in the absence of bystanders, help make opioid toxicity events functionally witnessed and in turn more likely to be successfully resuscitated.
