In preparation for the Tokyo 2020 Olympic and Paralympic Games, our hospital was responsible for accepting mainly media representatives, marketing partners, and other Games staff. Given that restricting our regular capacity to treat certain groups of patients could potentially result in social losses, to avoid this we made rigorous preparations for the entire hospital to accept Games-related patients. It was rational to set up a single 24-h contact point at the Emergency Department for making the decision on whether to accept the patient or not and for coordinating the patient's medical care. With respect to language support, International Health Care Center staffs were made available as interpreters on weekdays. Multilingual support was available all day via an application run on tablet devices. During a 67-day period, the hospital accepted 31 Games-related patients (mean age 43.4 years, male: female ratio 25:6). Eighteen patients were from Europe, 4 patients each were from North America and Asia, 2 each were from Central America, South America, and Africa, and 1 was from Oceania. The most common cause of visits was COVID-19, but none were severe cases. Other causes were diverse and included moderate and severe conditions. We summarized the challenges and experiences in handling Tokyo 2020 Games-related patients at a designated hospital during the COVID-19 pandemic

Multi-point scanning confocal microscopy using a Nipkow disk enables the acquisition of fluorescent images with high spatial and temporal resolutions. Like other single-point scanning confocal systems that use Galvano meter mirrors, a commercially available Nipkow spinning disk confocal unit, Yokogawa CSU10, requires lasers as the excitation light source. The choice of fluorescent dyes is strongly restricted, however, because only a limited number of laser lines can be introduced into a single confocal system. To overcome this problem, we developed an illumination system in which light from a mercury arc lamp is scrambled to make homogeneous light by passing it through a multi-mode optical fiber. This illumination system provides incoherent light with continuous wavelengths, enabling the observation of a wide range of fluorophores. Using this optical system, we demonstrate both the high-speed imaging (up to 100 Hz) of intracellular Ca2+ propagation, and the multi-color imaging of Ca2+ and PKC-γ dynamics in living cells.
