Emergence of a New Rust Disease of Virginia Creeper (Parthenocissus quinquefolia) through a Host Range Expansion of Neophysopella vitis

Virginia creeper (or five-leaved ivy; Parthenocissus quinquefolia) is one of the most popular and widely grown climbers worldwide. In September 2021, Virginia creeper leaves with typical rust symptom were found in an arboretum in Korea, with severe damage. Globally, there is no record of a rust disease on Virginia creeper. Using morphological investigation and molecular phylogenetic inferences, the rust agent was identified as Neophysopella vitis, which is a rust pathogen of other Parthenocissus spp. including Boston ivy (P. tricuspidata). Given that the two ivy plants, Virginia creeper and Boston ivy, have common habitats, especially on buildings and walls, throughout Korea, and that N. vitis is a ubiquitous rust species affecting Boston ivy in Korea, it is speculated that the host range of N. vitis may recently have expanded from Boston ivy to Virginia creeper. The present study reports a globally new rust disease on Virginia creeper, which could be a major threat to the ornamental creeper.

Intervention by PCT and Problems Awaiting Solution at Anjo Kosei Hospital: Usefulness of Rounds of Patients Receiving Opioids / 日本農村医学会雑誌

  In order to intervene in the management of pain of cancer from an early stage. Our palliative care team (PCT), including pharmacists, makes the ward rounds (screening rounds) of the patients receiving opioids at our hospital. The purpose of this study was to analyze the effects of screening rounds activity by the PCT and its current problems, and to explore how to resolve the problems. We retrospectively studied the records of 196 patients who had receivede interventions by the PCT, with regard to intervention status and prescription proposal (228 subjects) about drug therapy by us. Study groups were as follows: 103 patients to whom interventions were deliveed at the request of medical doctors (intervention request group) and 93 patients who had interventions by the PCT after PCT-screening rounds (screening group). PCT-screening rounds caused to increase the number of interventions by the PCT. After PCT-screening rounds, the cases of intervention started by the request of medical doctors, who had given no heed to PCT intervention, also increased in numher. In this study, some problems with palliative intervention were also brought to light. Even in the screening group where the PCT largely intervened, 33% of prescription proposal by the PCT was ignored. This problem may be, at least in part, due to inadequate communication between PCT and ward staff through an electronic medical recording card, leading to poor relationship between PCT and ward staff. In the future, the PCT needs to work cooperatively with ward staff through direct communication such as medical conference to perform better intervention.
