By use of 18 varieties of pesticide and six of their breakdown products, experiments were conducted to cause mutation and reversion in S. typhimurium TA98 and TA100 within a range of 0.01ug-100 ug/plate.
The results showed that Captan had mutagenic effects on TA98 and TA100. However, when S-9 mix was added, the number of revertant colonies ceased increasing.
Ethylenthio urea caused mutations in TA98. When S-9 mix was added, revertant colonies increased about twice the number in the control. In the absense of S-9 mix, the result was the same.

The need for palliative care for heart failure patients has been attracting attention, but the system for providing such care is not yet fully established in Japan. Iizuka Hospital is a 1048-bed acute care hospital located in Fukuoka, Japan. The Heart Support Team (HST) was established to provide palliative care for heart failure at the hospital. After the HST was launched in May 2017, 168 referrals for palliative care intervention for heart failure patients by March 2022. Twenty-five (14.8%) met the intervention cases’ additional palliative care treatment criteria. The Integrated Palliative Outcome Scale was administered to 11 consecutive patients from April 1 to 30, 2021. In establishing and operating the HST, the challenge was recruiting, training, and creating a system to sustain the system. Creating the HST in collaboration with staff specializing in palliative care, psychiatric care, and cardiovascular specialists was the first step in establishing a method for palliative care to heart failure patients in an acute care hospital.
