In this study, information on injectable anticancer drug use and additional fee for enhanced collaboration (AEC) and additional fee for specific drug management guidance 2 (ASD2) claims from the NDB Open Data Japan (NODJ) dataset and the number of patients with cancer according to sex and age from the National Cancer Registry (NCR) dataset were integrated and evaluated to determine the current status and challenges in pharmacist interventions for patients receiving cancer treatment. The NODJ data, including receipt data billed from 2020 to 2021, were obtained from the Ministry of Health, Labour and Welfare website. The use of injectable anticancer drugs decreased relative to the number of cancer patients aged ≥ 75 years compared to those aged < 75 years. Regarding injectable anticancer drug use, the number of AEC claims was similar between men and women, but the number of ASD2 claims was lower in men than in women. The number of times community pharmacists claimed their ASD2 was approximately 5% of the number of times hospital pharmacists claimed their AEC. This study revealed that several patients did not receive sufficient guidance from community pharmacists compared to hospital pharmacists, suggesting a potential insufficiency in the collaboration between the two groups.

Heme is an essential prosthetic molecule for life activities and is well known to act as the active center of many proteins, however, labile heme (LH) released from proteins is a harmful molecule that produces reactive oxygen species and must be strictly controlled. Recently, LH has been suggested to function as an important molecule for diverse physiological responses. Quantitative analysis of the intracellular dynamics of LH is essential for understanding its physiological functions, a substantially practical method has not been established. Here, we successfully developed an alternative method that can be used to complement quantification of the dynamics of intracellular LH using H-FluNox, an activity-based specific fluorescent probe recently constructed. Our newly established method should be effective in elucidating the physiological functions of LH.
