Purpose: The purpose of this study was to compare the retinal vascular caliber of COVID-19 patients with that of healthy subjects. Methods: This was a prospective case–control study. Forty-six patients who had COVID-19 were successfully treated, and 38 age- and gender-matched healthy subjects were enrolled in this study. Fundus photography was taken using fundus fluorescein angiography (FA; Visucam 500; Carl Zeiss Meditec, Jena, Germany). Retinal vascular caliber was analyzed with IVAN, a semi-automated retinal vascular analyzer (Nicole J. Ferrier, College of Engineering, Fundus Photography Reading Center, University of Wisconsin, Madison, WI, USA). Central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), and artery–vein ratio (AVR) were compared between groups. Results: The mean age was 37.8 ± 9.5 years in the COVID-19 group ( n = 46) and 40 ± 8 years in the control group ( n = 38) ( p = 0.45). The mean CRAE was 181.56 ± 6.40 in the COVID-19 group and 171.29 ± 15.06 in the control group ( p = 0.006). The mean CRVE was 226.34 ± 23.83 in the COVID-19 group and 210.94 ± 22.22 in the control group ( p = 0.044). AVR was 0.81 ± 0.09 in the COVID-19 group and 0.82 ± 0.13 in the control group ( p = 0.712). Conclusion: Patients who had COVID-19 have vasodilation in the retinal vascular structure after recovery. As they may be at risk of retinal vascular disease, COVID-19 patients must be followed after recovery.

Results are reported of the implementation of an engineer-in-residence concept in the Department of Civil Engineering and Mechanics at the University of Wisconsin–Milwaukee College of Engineering and Applied Science. This concept brings an experienced practitioner to campus specifically to mentor students and faculty in the application of engineering and management principles to real-life problems and to provide additional relevancy to the education process. Success of the concept is measured by evaluations completed by students and faculty. On the basis of the findings of these evaluations, the concept is a promising way to provide expanded relevancy to a transportation education program.

Group contributions have been determined allowing the calculation of free energies of formation in aqueous solution for organic compounds containing carbon, hydrogen, and oxygen. The system works well for monofunctional compounds. The available literature data for 198 compounds can be accommodated using 79 parameters with an rms deviation of 0.74 kcal/mol.
