The switch to online instruction during the COVID-19 pandemic forced educators to adapt hands-on environmental engineering experiments to a remote curriculum previously conducted in a laboratory using expensive analytical instruments (> $2000 per device). Here, we describe how we developed a low-cost (<$200) aerosol sensor platform as a successful solution for supporting remote laboratories on air quality for environmental engineering courses in Spring 2021, and continued for in-person classes in Spring 2022. This sensor platform, called HazeL (Haze Laser Sensor), consists of an externally mounted aerosol sensor, a GPS receiver, and temperature and pressure sensors coupled to an Arduino MKR WiFi 1010 microcontroller connected via a Grove system. Using a project-based learning approach and implementing the scientific method, students worked asynchronously to design experiments, collect aerosol measurements, and analyze and visualize data using the R programming language. Students generated hypotheses regarding factors affecting air pollution, measured ≥0.3 μm particles in different locations, tested differences between samples, and rejected the null hypothesis if appropriate. HazeL was also used for projects on data processing and statistical inference in an upper-level computational course. We present an instructional guide on manufacturing the HazeL platform and using it as a teaching tool for enhancing student experiential learning, participation, and engagement.

OBJECTIVE Increasing workforce capacity to provide knowledgeable, skilled, and affirming care for transgender and gender diverse people is critical to reduce health inequities; however, few clinicians receive sufficient training on this topic. This article describes Advancing Excellence in Transgender Health (AETH), an annual international conference that offers continuing professional development on evidence-based medical and behavioral healthcare for transgender and gender diverse people across the lifespan. METHODS Registration data and post-conference evaluation data were descriptively analyzed to assess conference reach, participant satisfaction, and participant intentions to change practice. RESULTS Between 2015 and 2022, AETH trained 2677 participants from all US states and 24 countries. Based on post-conference evaluations, 2017-2022, participant satisfaction was high (mean ≥4.4 on a 5-point scale) on all measures, including meeting learning objectives, quality of presentations, and relevance to practice. Participants reported intentions to: implement new information or skills (86.7%); create or revise protocols, policies, and/or procedures (63.2%); and seek additional information (64.2%). To increase equity, the conference waives fees for transgender and gender diverse participants and offers free online sessions. The conference also holds sessions specifically for transgender and gender diverse participants to promote opportunities for community-building, self-care, and professional networking. CONCLUSION The broad reach of AETH demonstrates a large demand for more continuing professional development on transgender and gender diverse healthcare. This conference has expanded the availability of training designed to increase and enhance clinical workforce capacity to meet the health needs of transgender and gender diverse communities in the US and across the world.

We report the results of a survey on HIV pre-exposure prophylaxis (PrEP) perceptions, capacity, and barriers at federally qualified health centers (FQHCs) in high-HIV-burden jurisdictions in the United States. Healthcare workers at FQHCs identified multiple barriers to, and strategies for, improving PrEP implementation.
