RESUMEN
The increased numbers of older and frail patients with heart failure (HF) means there is an urgent need to establish regional collaborative systems for medical and nursing care. However, expectations related to collaborative HF care among medical and care staff remain unclear. We conducted a questionnaire survey with staff in hospitals, clinics, and nursing care facilities (NCFs) who had experienced collaboration through the common HF collaborative pathway in the western region of Tottori Prefecture, Japan, from July 2019 to July 2020. We received 150 responses from hospitals and 41 responses from clinics and NCFs. Following introduction of the collaborative pathway, 57% of respondents from hospitals, 35% from clinics, and 71% from NCFs rated collaboration as improved. Staff from hospitals and clinics were most satisfied with improved education interventions following implementation of the collaborative pathway, and NCF staff were most satisfied with improved information sharing. Staff from hospitals and NCFs placed the highest importance on improving information sharing through collaboration, and clinic staff placed the highest importance on improving efficiency. The needs for collaborative HF care differ between hospitals, clinics, and NCFs. A collaboration program should be designed to meet the different needs of diverse staff in the community.

Background: With the aging of heart failure (HF) patients, collaboration between medical and nursing care facilities is essential for HF care. The aims of this study were: (1) to identify the factors that affect willingness of nursing care staffs to cooperate with HF care; (2) to test whether the internet video education is useful in improving their willingness to collaborate. Methods: A web-based questionnaire was e-mailed to 417 registered medical corporations that operated nursing care facilities in the prefecture where the authors work. Medical and care staff working at each facility were asked their willingness to cooperate with HF care and their problems about collaboration. Machine learning analysis was used to assess the factors associated with unwillingness to cooperate. After watching a 6-min YouTube video explaining HF and community collaboration, we reaffirmed their willingness to cooperate. Results: We received responses from 76 medical and care staff members. Before watching the video, 32.9% of participants stated that they were unwilling to cooperate with HF care. Machine learning analysis showed that job types, perceived problems of collaboration, and low opportunities to learn about HF were associated with unwillingness to cooperation. After watching the video, we observed an increase from 67.1% to 80.3% (p < 0.05) of participants willing to cooperate with HF care. Conclusions: Job types, perceived problems of collaboration, and low opportunities to learn about HF are associated with unwillingness of nursing care staff for HF care. Internet videos are potential learning tool that can easily promote community collaboration for HF.
RESUMEN
Background: Evidence on transitional care for heart failure (HF) in Japan is limited. MethodsâandâResults: We implemented a transitional HF management program in rural Japan in 2019. This involved collaboration with general practitioners or nursing care facilities and included symptom monitoring by medical/nursing staff using a handbook; standardized discharge care planning and information sharing on self-care and advance care planning using a collaborative sheet; and sharing expertise on HF management via manuals. We compared the outcomes within 1 year of discharge among patients hospitalized with HF in the 2 years before program implementation (2017-2018; historical control, n=198), in the first 2 years after program implementation (2019-2020; Intervention Phase 1, n=205), and in the second 2 years, following program revision and regional dissemination (2021-2022; Intervention Phase 2, n=195). HF readmission rates gradually decreased over Phases 1 and 2 (P<0.05). This association was consistent regardless of physician expertise, follow-up institution, or the use of nursing care services (P>0.1 for interaction). Mortality rates remained unchanged, but significantly more patients received end-of-life care at home in Phase 2 than before (P<0.05). Conclusions: The implementation of a transitional care program was associated with decreased HF readmissions and increased end-of-life care at home for HF patients in rural Japan.
RESUMEN
BACKGROUND/AIM: Immune checkpoint inhibitors (ICIs) play an important role in the treatment of esophageal cancer (EC). However, few patients achieve long-term survival, and some patients develop serious immune-related adverse events (irAEs). Reliable predictive biomarkers of efficacy and safety need to be established in order to improve efficacy. We retrospectively analyzed the outcomes of nivolumab monotherapy on EC at Showa University, Department of Medicine, to identify biomarkers and characteristics of patients who benefit from ICI monotherapy. PATIENTS AND METHODS: Eighty-six patients with EC who received nivolumab monotherapy were included in the present study. Patient characteristics, efficacy, and safety were analyzed. A multivariable analysis evaluated the correlation among overall survival (OS), progression-free survival (PFS), best overall response (BOR), irAEs, and the following variables: sex, age, performance status (PS), neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP) level, albumin level, and body-mass index before treatment. RESULTS: Median PFS was 3.1 months, and median OS was 9.0 months. In multivariable analysis, pretreatment PS, NLR, and sex were significantly correlated with OS and PFS. NLR <3.3 predicted longer survival (median OS 17.5 vs. 6.4 months for NLR ≥3.3; p<0.001). Median OS was 10.6 months for PS 0-1 and 1.3 months for PS 2-3 (p<0.001). NLR remained significantly predictive in the PS 0-1 group. The development of irAEs was significantly associated with increased OS and PFS. CONCLUSION: Patients with low NLR and good PS before treatment may maximize the benefits of ICIs. A low NLR may be an indicator of higher immunocompetence for anti-tumor immunity, suggesting that NLR may be a convenient predictive biomarker in daily practice.

BACKGROUND/AIM: The response rate to immune checkpoint inhibitors (ICIs) is approximately 10%-30% and only in a few cancer types. In the present study, we determined whether non-classical monocytes (NCMs) could enhance ICI efficacy in colon cancer using a syngeneic mouse model. MATERIALS AND METHODS: The MC38 C57BL/6 mouse colon cancer model was used. Cells collected from the bone marrow of C57BL/6 mice were cultured, and NCMs were fractionated by cell sorting and administered via the tail veins to the mice implanted with MC38 cells. The anti-mouse PD-L1 antibody was administered three times, and tumor volume and overall survival were observed. RESULTS: More tumors were eradicated and more complete response occurred, after cotreatment with ICIs and NCMs than after treatment with ICIs alone. Moreover, no efficacy was observed when NCMs were administered alone. CONCLUSION: NCMs enhance ICI efficacy. The underlying mechanisms and clinical applications will be studied in the future.

Introduction: Programmed cell death ligand 1 (PD-L1) expression in tumor tissues is measured as a predictor of the therapeutic efficacy of immune checkpoint inhibitors (ICIs) in many cancer types. PD-L1 expression is evaluated by immunohistochemical staining using 3,3´-diaminobenzidine (DAB) chronogenesis (IHC-DAB); however, quantitative and reproducibility issues remain. We focused on a highly sensitive quantitative immunohistochemical method using phosphor-integrated dots (PIDs), which are fluorescent nanoparticles, and evaluated PD-L1 expression between the PID method and conventional DAB method. Methods: In total, 155 patients with metastatic or recurrent cancer treated with ICIs were enrolled from four university hospitals. Tumor tissue specimens collected before treatment were subjected to immunohistochemical staining with both the PID and conventional DAB methods to evaluate PD-L1 protein expression. Results: PD-L1 expression assessed using the PID and DAB methods was positively correlated. We quantified PD-L1 expression using the PID method and calculated PD-L1 PID scores. The PID score was significantly higher in the responder group than in the non-responder group. Survival analysis demonstrated that PD-L1 expression evaluated using the IHC-DAB method was not associated with progression-free survival (PFS) or overall survival (OS). Yet, PFS and OS were strikingly prolonged in the high PD-L1 PID score group. Conclusion: Quantification of PD-L1 expression as a PID score was more effective in predicting the treatment efficacy and prognosis of patients with cancer treated with ICIs. The quantitative evaluation of PD-L1 expression using the PID method is a novel strategy for protein detection. It is highly significant that the PID method was able to identify a group of patients with a favorable prognosis who could not be identified by the conventional DAB method.
