Risk stratification by renal function and NYHA class in patients with hypotension initiated on sacubitril/valsartan: a retrospective cohort study from 17 centres in Japan.

BACKGROUND: Patients with heart failure exhibiting low systolic blood pressure (SBP) have a poor prognosis. Sacubitril/valsartan reduces cardiovascular events; however, its use in patients with low SBP has not been fully examined. Therefore, in this study, we aimed to investigate the association between baseline SBP and adverse events (AEs) in patients starting sacubitril/valsartan therapy using data from a real-world registry in Japan. METHODS: We analysed data from a multicentre retrospective study, including patients who initiated sacubitril/valsartan between August 2020 and August 2021. The patients were categorised into five groups based on their baseline SBP (<100, 100-109, 110-119, 120-129 and ≥130 mm Hg). The composite of AEs occurring within 3 months according to baseline SBP and the patient characteristics associated with AEs in a baseline SBP <110 mm Hg were analysed. RESULTS: Among the 964 patients newly prescribed sacubitril/valsartan, the median (IQR) age was 73 (61-80) years, and 388 (40.2%) patients had a baseline SBP <110 mm Hg. AEs occurred in 24% (n=232) of patients. The adjusted ORs for all AEs were 1.91 (95% CI (CI) 1.13-3.23; p=0.02) for the SBP <100 mm Hg group and 3.33 (95% CI 1.98 to 5.59; p<0.001) for the SBP 100-109 mm Hg group, compared with the SBP 110-119 mm Hg group. In patients with a baseline SBP <110 mm Hg, factors associated with an increased risk of AEs included a higher New York Heart Association class (II, III or IV) and a lower estimated glomerular filtration rate <30 mL/min/1.73 m2. CONCLUSIONS: Caution is needed when initiating sacubitril/valsartan in patients with lower baseline SBP. The severity of heart failure and kidney function may be useful for risk stratification in these high-risk patients.

Uptitration of Sacubitril/Valsartan and Outcomes in Patients With Heart Failure　- Insight From the REVIEW-HF Registry.

BACKGROUND: Guideline-directed medical therapy has become an important component of heart failure (HF) therapy, with sacubitril/valsartan as one of the recommended drugs; however, the real-world prognostic implications of sacubitril/valsartan uptitration are unclear. METHODS AND RESULTS: Patients with HF newly initiated on sacubitril/valsartan were registered in a retrospective multicenter study (REVIEW-HF). In all, 995 patients were divided into 3 groups according to the maximum dose achieved: high dose, sacubitril/valsartan 400 mg; intermediate dose, sacubitril/valsartan 200-<400 mg; and low dose, sacubitril/valsartan <200 mg. A total of 397 (39.9%) patients received high-dose sacubitril/valsartan; they had a significantly lower risk of mortality or HF hospitalization than patients in the low-dose (hazard ratio [HR] 0.39; 95% confidence interval [CI] 0.29-0.53; P<0.001) and intermediate-dose (HR 0.64; 95% CI 0.45-0.94; P=0.03) groups. In the multivariable Cox regression model, higher systolic blood pressure and maintained geriatric nutritional risk index were significantly associated with a higher incidence of achieving a high dose of sacubitril/valsartan. Patients who did not receive high-dose sacubitril/valsartan experienced more hypotension during the follow-up period, whereas hyperkalemia, severe renal events, and angioedema did not differ across the achieved dose classifications. CONCLUSIONS: Patients who achieved sacubitril/valsartan uptitration had a better prognosis than those who did not. Before sacubitril/valsartan uptitration, patients need to monitor blood pressure closely to prevent worsening events.

A Web-Based Education Program About Primary Palliative Care for Heart Failure: A Study Protocol of Wait-Listed Randomized Controlled Trial.

BACKGROUND: The number of patients with heart failure (HF) is rapidly increasing as palliative care is being integrated into HF management and the need for a nursing workforce to meet these demands grows. To address this, we have developed a Web-based educational program on primary palliative care for HF among general registered nurses caring for patients with HF in Japan. OBJECTIVE: The aim of this study was to evaluate the program's effectiveness on nurse-reported palliative care practice, difficulty, and knowledge. METHODS: In this open-label, individual-level, wait-listed randomized controlled trial, 150 Japanese general registered nurses, with experience in caring for patients with HF and clinical ladder level ≥ 2 in inpatient, outpatient, and home-visiting care settings, will be randomly divided (1:1 ratio) into a Web-based educational program group and a wait-list control group. The follow-up period is 6 months after the intervention. The primary outcome is the nurse-reported practice score in primary palliative care, and the secondary outcomes are the nurse-reported difficulties score and knowledge score. CONCLUSIONS AND CLINICAL IMPLICATIONS: We herein describe the study protocol of a wait-listed randomized controlled trial regarding a Web-based educational program, which is a novel approach for these nurses. If the results of this study support our hypothesis, they could help expand primary palliative care, including daily nursing practices, such as symptom management and interdisciplinary collaboration, in the field of cardiovascular nursing.

Bereaved family members' perspectives on quality of death in deceased acute cardiovascular disease patients compared with cancer patients - a comparison of the J-HOPE3 study and the quality of palliative care in heart disease (Q-PACH) study.

BACKGROUND: Outcome measures during acute cardiovascular disease (CVD) phases, such as quality of death, have not been thoroughly evaluated. This is the first study that compared the family members' perceptions of quality of death in deceased CVD patients and in deceased cancer patients using a bereaved family survey. METHODS: Retrospectively sent questionnaire to consecutive family members of deceased patients with CVD from ten tertiary hospitals from October 2017 to August 2018. We used the short version of the Good Death Inventory (GDI) and assessed overall care satisfaction. Referencing the GDI, the quality of death was compared between CVD patients admitted to a non-palliative care unit (non-PCU) and cancer patients in palliative care units (PCU) and non-PCUs in the Japan Hospice and Palliative Care Evaluation Study (J-HOPE Study). Additionally, in the adjusted analysis, multivariable linear regression was performed for total GDI score adjusted by the patient and participant characteristics to estimate the difference between CVD and other patients. RESULTS: Of the 243 bereaved family responses in agreement (response rate: 58.7%) for CVD patients, deceased patients comprised 133 (54.7%) men who were 80.2 ± 12.2 years old on admission. The GDI score among CVD patients (75.0 ± 15.7) was lower (worse) than that of cancer patients in the PCUs (80.2 ± 14.3), but higher than in non-PCUs (74.4 ± 15.2). After adjustment, the total GDI score for CVD patients was 7.10 points lower [95% CI: 5.22-8.97] than for cancer patients in PCUs and showed no significant differences compared with those in non-PCUs (estimates, 1.62; 95% CI [-0.46 to 5.22]). CONCLUSIONS: The quality of death perceived by bereaved family members among deceased acute CVD patients did not differ significantly from that of deceased cancer patients in general wards, however, was significantly lower than that of deceased cancer patients admitted in PCUs.

[Successful induction therapy for acute myeloid leukemia under management with extracorporeal membrane oxygenation].

A 53-year-old woman presented with shortness of breath and hyperleukocytosis and was admitted to our hospital. Shortly after, she went into cardiopulmonary arrest and was resuscitated. Her white blood cell count was 566,000/µl, with 94.5% cup-like blasts positive for MPO staining and FLT3-ITD positive, so she was diagnosed with acute myeloid leukemia (AML) M1. She also had disseminated intravascular coagulation and tumor lysis syndrome. Extracorporeal membrane oxygenation (ECMO) was started to manage bilateral pulmonary thromboembolism that had developed due to deep vein thrombosis, and induction therapy was performed under ECMO. On the third day of illness, the patient developed cerebral hemorrhage. Hematological remission was confirmed on the 39th day of illness. After consolidation therapy with chemotherapy and an FLT3 inhibitor, she underwent allogeneic hematopoietic stem cell transplantation, and remains alive. Case reports suggest strong evidence of mortality benefit from ECMO in patients with hematologic malignancies, particularly when ECMO served as a bridge through chemotherapy. Our patient suffered from cardiopulmonary arrest due to hyperleukocytosis and pulmonary thromboembolism, but was saved by induction of remission under ECMO. Improvements in supportive care should lead to reduction in early deaths during induction therapy.

Public awareness of palliative care for heart failure in Japan: A cross-sectional study.

BACKGROUND: Palliative care (PC) benefits cancer patients and those with heart failure (HF), improving quality of life and symptom burden. Despite guidelines recommending the integration of PC into HF care, its use remains inadequate, partly due to insufficient public awareness. This study aimed to assess the public awareness of PC for HF in Japan and identify factors associated with awareness. METHODS: A cross-sectional online survey was conducted from March 6-13, 2023, using a panel operated by Intage Inc. (Tokyo, Japan), which has a pool of 3.78 million potential Japanese respondents. The survey included 51,790 participants, matched for sex, age, and region of residence. Participants were asked about their awareness of PC eligibility for HF, along with demographic information, history of hospitalization for sudden illness, outpatient visits, and health status in the previous 2 years. The χ2 test and Cramer's V were used to analyze associations between awareness and variables, and multivariate logistic regression was used to estimate awareness predictors. RESULTS: In total, 91 % of participants were unaware of PC eligibility for HF. Age group, healthcare professional occupation, and history of hospitalization for acute myocardial infarction, acute HF, acute pulmonary embolism, and ruptured aortic aneurysm had weak to moderate associations with awareness. Multivariate analysis revealed that a history of hospitalization for sudden cardiovascular illness and being a healthcare professional were positively related to awareness, while age, female sex, and being married were associated with lower odds of awareness. CONCLUSION: The low public awareness of PC for HF in Japan underscores the importance of increasing awareness of the eligibility of PC for HF, as well as cancer, to integrate PC into HF practice as basic care.

Geographic variation of mutagenic exposures in kidney cancer genomes.

International differences in the incidence of many cancer types indicate the existence of carcinogen exposures that have not yet been identified by conventional epidemiology make a substantial contribution to cancer burden1. In clear cell renal cell carcinoma, obesity, hypertension and tobacco smoking are risk factors, but they do not explain the geographical variation in its incidence2. Underlying causes can be inferred by sequencing the genomes of cancers from populations with different incidence rates and detecting differences in patterns of somatic mutations. Here we sequenced 962 clear cell renal cell carcinomas from 11 countries with varying incidence. The somatic mutation profiles differed between countries. In Romania, Serbia and Thailand, mutational signatures characteristic of aristolochic acid compounds were present in most cases, but these were rare elsewhere. In Japan, a mutational signature of unknown cause was found in more than 70% of cases but in less than 2% elsewhere. A further mutational signature of unknown cause was ubiquitous but exhibited higher mutation loads in countries with higher incidence rates of kidney cancer. Known signatures of tobacco smoking correlated with tobacco consumption, but no signature was associated with obesity or hypertension, suggesting that non-mutagenic mechanisms of action underlie these risk factors. The results of this study indicate the existence of multiple, geographically variable, mutagenic exposures that potentially affect tens of millions of people and illustrate the opportunities for new insights into cancer causation through large-scale global cancer genomics.

Differential Hypoxia Risk in Cardiopulmonary Arrest Patients Undergoing Veno-Arterial Extracorporeal Membrane Oxygenation and IMPELLA Support.

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a therapeutic strategy for managing cardiogenic shock. However, it carries the risk of cardiogenic pulmonary edema, potentially leading to differential hypoxia. Although IMPELLA can mitigate pulmonary congestion, the combination of VA-ECMO and IMPELLA has frequently resulted in differential hypoxia, requiring a transition from VA-ECMO to veno-arteriovenous extracorporeal membrane oxygenation (VAV-ECMO). Therefore, this study aimed to examine the influence of IMPELLA on the incidence of differential hypoxia, necessitating a shift to VAV-ECMO. This single-center, retrospective, observational study included patients who experienced cardiopulmonary arrest and received treatment with VA-ECMO combined with an intra-aortic balloon pump (IABP) or IMPELLA between 2017 and 2022. The primary endpoint assessed the incidence of differential hypoxia, necessitating a switch to VAV-ECMO. Patients with cardiopulmonary arrest received treatment with VA-ECMO in combination with IABP (N = 28) or IMPELLA (N = 29). There was a significant increase in differential hypoxia 96 hours post-VA-ECMO initiation in the IMPELLA group, necessitating a transition to VAV-ECMO. The combination of VA-ECMO and IMPELLA in patients experiencing cardiopulmonary arrest may significantly increase the risk of differential hypoxia. A multidisciplinary approach employing mechanical circulatory support is crucial, with ongoing consideration of the potential risks associated with differential hypoxia.

Antitumor Activity of Tasurgratinib as an Orally Available FGFR1-3 Inhibitor in Cholangiocarcinoma Models With FGFR2-fusion.

BACKGROUND/AIM: Cholangiocarcinoma (CCA) is an aggressive tumor with limited treatment options especially in 2nd line or later treatments. Targeting fibroblast growth factor receptor (FGFR) 2 has recently emerged as a promising treatment option for patients with CCA harboring FGFR2-fusion. This study investigated the antitumor activities of tasurgratinib as an orally available FGFR1-3 inhibitor, in preclinical FGFR2-driven CCA models. MATERIALS AND METHODS: Antitumor activities of tasurgratinib were examined in vitro and in vivo using NIH/3T3 cells expressing FGFR2-fusion as FGFR2-driven CCA models, and in vivo using a CCA patient-derived xenograft model. The molecular mechanism of action of tasurgratinib was elucidated through co-crystal structure analysis with FGFR1, manual complex model analysis with FGFR2, and binding kinetics analysis with FGFR2. Furthermore, the cell-based inhibitory activities against acquired resistant FGFR2 mutations in patients with CCA treated with FGFR inhibitors were evaluated. RESULTS: Tasurgratinib showed antitumor activity in preclinical FGFR2-driven CCA models by inhibiting the FGFR signaling pathway in vitro and in vivo. Furthermore, cell-based target engagement assays indicated that tasurgratinib had potent inhibitory activities against FGFR2 mutations, such as N549H/K, which are the major acquired mutations in CCA. We also confirmed that tasurgratinib exhibited fast association and slow dissociation kinetics with FGFR2, binding to the ATP-binding site and the neighboring region, and adopting an Asp-Phe-Gly (DFG)-"in" conformation. CONCLUSION: These data demonstrate the therapeutic potential of tasurgratinib in FGFR2-driven CCA and provide molecular mechanistic insights into its unique inhibitory profile against secondary FGFR2 resistance mutations in patients with CCA treated with FGFR inhibitors.

Spatial and single-cell colocalisation analysis reveals MDK-mediated immunosuppressive environment with regulatory T cells in colorectal carcinogenesis.

BACKGROUND: Cell-cell interaction factors that facilitate the progression of adenoma to sporadic colorectal cancer (CRC) remain unclear, thereby hindering patient survival. METHODS: We performed spatial transcriptomics on five early CRC cases, which included adenoma and carcinoma, and one advanced CRC. To elucidate cell-cell interactions within the tumour microenvironment (TME), we investigated the colocalisation network at single-cell resolution using a deep generative model for colocalisation analysis, combined with a single-cell transcriptome, and assessed the clinical significance in CRC patients. FINDINGS: CRC cells colocalised with regulatory T cells (Tregs) at the adenoma-carcinoma interface. At early-stage carcinogenesis, cell-cell interaction inference between colocalised adenoma and cancer epithelial cells and Tregs based on the spatial distribution of single cells highlighted midkine (MDK) as a prominent signalling molecule sent from tumour epithelial cells to Tregs. Interaction between MDK-high CRC cells and SPP1+ macrophages and stromal cells proved to be the mechanism underlying immunosuppression in the TME. Additionally, we identified syndecan4 (SDC4) as a receptor for MDK associated with Treg colocalisation. Finally, clinical analysis using CRC datasets indicated that increased MDK/SDC4 levels correlated with poor overall survival in CRC patients. INTERPRETATION: MDK is involved in the immune tolerance shown by Tregs to tumour growth. MDK-mediated formation of the TME could be a potential target for early diagnosis and treatment of CRC.

Genomic and Pathologic Profiling of Very Well-Differentiated Gastric Adenocarcinoma of Intestinal Type: A Study With Emphasis on Diffuse-Type Transformation.

Very well-differentiated adenocarcinoma of intestinal type is a distinct subtype of gastric cancer characterized by anastomosing glands with a hand-in-hand pattern and low-grade cytologic atypia resembling intestinal metaplasia. This is a slow-growing neoplasm with an indolent clinical course; however, a subset demonstrates transformation into adenocarcinoma with higher-grade histology, typically diffuse-type carcinoma, and behaves aggressively. This study aimed to better characterize the genomic and pathologic features, with a focus on factors associated with diffuse-type transformation. A total of 58 cases with (n=31) and without (n=27) diffuse-type transformation were analyzed for molecular and pathologic features. First, comprehensive deep DNA sequencing was conducted in 18 cases (discovery cohort), followed by a digital droplet polymerase chain reaction of hot spot RHOA mutations in 40 cases (validation cohort). In total, RHOA mutations were the most common alteration (34%), followed by loss of ARID1A (12%), p53 alterations (10%), and CLDN18 :: ARHGAP26/6 fusions (3.4%). FGFR2 amplification was identified in an advanced case with a p53 alteration. Altered p53 expression was recognized only in higher-grade components and was significantly associated with advanced disease ( P =0.0015) and diffuse-type transformation ( P =0.026). A mixed mucin phenotype was also strongly correlated with advanced disease ( P <0.001) and diffuse-type transformation ( P <0.001). Decreased E-cadherin expression was frequently observed (74%) in poorly cohesive components. This study demonstrated that a subset of RHOA -mutant diffuse-type gastric cancers develops through the transformation of very well-differentiated adenocarcinoma of intestinal type. Our observations suggest a mixed mucin phenotype as a risk factor and alterations in p53 and E-cadherin as drivers of diffuse-type transformation.

Molecular subtypes of lung adenocarcinoma present distinct immune tumor microenvironments.

Overcoming resistance to immune checkpoint inhibitors is an important issue in patients with non-small-cell lung cancer (NSCLC). Transcriptome analysis shows that adenocarcinoma can be divided into three molecular subtypes: terminal respiratory unit (TRU), proximal proliferative (PP), and proximal inflammatory (PI), and squamous cell carcinoma (LUSQ) into four. However, the immunological characteristics of these subtypes are not fully understood. In this study, we investigated the immune landscape of NSCLC tissues in molecular subtypes using a multi-omics dataset, including tumor-infiltrating leukocytes (TILs) analyzed using flow cytometry, RNA sequences, whole exome sequences, metabolomic analysis, and clinicopathologic findings. In the PI subtype, the number of TILs increased and the immune response in the tumor microenvironment (TME) was activated, as indicated by high levels of tertiary lymphoid structures, and high cytotoxic marker levels. Patient prognosis was worse in the PP subtype than in other adenocarcinoma subtypes. Glucose transporter 1 (GLUT1) expression levels were upregulated and lactate accumulated in the TME of the PP subtype. This could lead to the formation of an immunosuppressive TME, including the inactivation of antigen-presenting cells. The TRU subtype had low biological malignancy and "cold" tumor-immune phenotypes. Squamous cell carcinoma (LUSQ) did not show distinct immunological characteristics in its respective subtypes. Elucidation of the immune characteristics of molecular subtypes could lead to the development of personalized immune therapy for lung cancer. Immune checkpoint inhibitors could be an effective treatment for the PI subtype. Glycolysis is a potential target for converting an immunosuppressive TME into an antitumorigenic TME in the PP subtype.

Home Treatment for Active Cancer Patients With Low-Risk Pulmonary Embolism　- A Predetermined Companion Report From the ONCO PE Trial.

BACKGROUND: Patients with appropriately selected low-risk pulmonary embolism (PE) can be treated at home, although it has been controversial whether applies to patients with cancer, who are considered not to be at low risk.Methods and Results: The current predetermined companion report from the ONCO PE trial evaluated the 3-month clinical outcomes of patients with home treatment and those with in-hospital treatment. The ONCO PE trial was a multicenter, randomized clinical trial among 32 institutions in Japan investigating the optimal duration of rivaroxaban treatment in cancer-associated PE patients with a score of 1 using the simplified version of the Pulmonary Embolism Severity Index (sPESI). Among 178 study patients, there were 66 (37%) in the home treatment group and 112 (63%) in the in-hospital treatment group. The primary endpoint of a composite of PE-related death, recurrent venous thromboembolism (VTE) and major bleeding occurred in 3 patients (4.6% [0.0-9.6%]) in the home treatment group and in 2 patients (1.8% [0.0-4.3%]) in the in-hospital treatment group. In the home treatment group, there were no cases of PE-related death or recurrent VTE, but major bleeding occurred in 3 patients (4.6% [0.0-9.6%]), and 2 patients (3.0% [0.0-7.2%]) required hospitalization due to bleeding events. CONCLUSIONS: Active cancer patients with PE of sPESI score=1 could be potential candidates for home treatment.

Comparison of the treatment status of patients with acute heart failure before and during the COVID-19 pandemic - Observational cohort study using Japanese administrative data.

BACKGROUND: There is a concern that the coronavirus disease 2019 (COVID-19) pandemic has led to underutilization of non-invasive positive pressure ventilation (NPPV) in patients with acute heart failure (HF). We investigated the alterations in clinical management of acute HF during the COVID-19 pandemic. METHODS AND RESULTS: This study was an observational study of patients treated in emergency care with acute HF, using a Japanese Administrative database for a period before and during the COVID-19 pandemic. Of the 9081 overall eligible patients, the ratio of patients receiving NPPV and tracheal intubation during to before the COVID-19 pandemic were 0.88 [95 % confidence interval (CI): 0.80, 0.96] and 1.38 (95 % CI: 1.11, 1.71), respectively. Propensity score matching in patients treated in COVID-19 receiving facilities and emergency declaration response areas showed that ratio of NPPV and tracheal intubation during to before the COVID-19 pandemic were 0.88 (95 % CI: 0.76, 1.03), and 1.65 (95 % CI: 1.19, 2.28), respectively. CONCLUSIONS: The implementation rate of NPPV decreased significantly in eligible patients, with a decreasing trend observed in patient populations in COVID-19 receiving facilities and emergency declaration response areas. Tracheal intubation increased in all populations.

Genomic and epigenomic integrative subtypes of renal cell carcinoma in a Japanese cohort.

Renal cell carcinoma (RCC) comprises several histological types characterised by different genomic and epigenomic aberrations; however, the molecular pathogenesis of each type still requires further exploration. We perform whole-genome sequencing of 128 Japanese RCC cases of different histology to elucidate the significant somatic alterations and mutagenesis processes. We also perform transcriptomic and epigenomic sequencing to identify distinguishing features, including assay for transposase-accessible chromatin sequencing (ATAC-seq) and methyl sequencing. Genomic analysis reveals that the mutational signature differs among the histological types, suggesting that different carcinogenic factors drive each histology. From the ATAC-seq results, master transcription factors are identified for each histology. Furthermore, clear cell RCC is classified into three epi-subtypes, one of which expresses highly immune checkpoint molecules with frequent loss of chromosome 14q. These genomic and epigenomic features may lead to the development of effective therapeutic strategies for RCC.

Relevant adverse events and drug discontinuation of sacubitril/valsartan in a real-world Japanese cohort: REVIEW-HF registry.

BACKGROUND: The characteristics, tolerability, and outcomes in patients with heart failure (HF) who are treated with sacubitril/valsartan remain unclear in Japan. METHODS: We conducted a nationwide multicenter study to evaluate the features and outcomes of patients newly prescribed sacubitril/valsartan for the management of HF. We analyzed adverse events (AEs) related to sacubitril/valsartan at 3 months, which were defined as hypotension, worsening renal function, hyperkalemia, and angioedema. Additionally, the association between AEs and outcomes was examined. RESULTS: Among 993 patients, the mean age was 70 years and 291 (29.3 %) were female, and 22.8 % had left ventricular ejection fraction ≥50 %. Of them, 20.8 % had systolic blood pressure (sBP) <100 mmHg, and 19.5 % had estimated glomerular filtration rate (eGFR) <30 ml/min/1.73 m2 at baseline, which were the populations excluded from the eligibility in landmark trials. AEs related to sacubitril/valsartan were observed in 22.5 % of the patients at 3 months. Overall, 22.6 % of patients discontinued sacubitril/valsartan, and hypotension was the most common event leading to drug discontinuation. After adjustment, patients who had worse HF symptoms (New York Heart Association III or IV), sBP <100 mmHg, and eGFR <30 ml/min/1.73 m2 were associated with a higher risk of AEs related to sacubitril/valsartan. Additionally, patients experiencing AEs had a higher risk of cardiovascular death or HF hospitalization than those who did not. CONCLUSION: In Japan, sacubitril/valsartan was also prescribed to patients not eligible for landmark trials, and AEs were observed at a relatively high rate from soon after treatment initiation. Physicians should closely monitor patients for these events, especially in patients anticipated to have a higher risk of AEs.

End-of-Life Discussions and Their Timing for Patients With Cardiovascular Diseases　- From the Perspective of Bereaved Family Members.

BACKGROUND: Enhanced discussions regarding end-of-life (EOL) are crucial to provide appropriate care for seriously ill patients. However, the current status of EOL discussions, especially their timing and influencing factors, among patients with cardiovascular diseases (CVD) remains unknown.Methods and Results: We conducted a cross-sectional questionnaire survey of bereaved family members of CVD patients who died at 10 tertiary care institutes in Japan. In all, 286 bereaved family members (38.2% male; median age 66.0 [interquartile range 58.0-73.0] years) of CVD patients were enrolled; of these, 200 (69.9%) reported that their families had had EOL discussions with physicians. The major topic discussed was resuscitation (79.0%), and 21.5% discussed the place of EOL care. Most discussions were held during hospitalization of the patient (88.2%). More than half (57.1%) the discussions were initiated less than 1 month before the patient died, and 22.6% of family members felt that this timing of EOL discussions was late. Bereaved family members' perception of late EOL discussions was associated with the family members aggressive attitude towards life-prolonging treatment, less preparedness for bereavement, and less satisfaction with EOL care. CONCLUSIONS: Approximately 70% of bereaved family members of CVD patients had EOL discussions, which were often held shortly before the patient died. Further research is required to establish an ideal approach to EOL discussions at an appropriate time, which may improve the quality of EOL care.

Sleeping Beauty transposon mutagenesis identified genes and pathways involved in inflammation-associated colon tumor development.

Chronic inflammation promotes development and progression of colorectal cancer (CRC). To comprehensively understand the molecular mechanisms underlying the development and progression of inflamed CRC, we perform in vivo screening and identify 142 genes that are frequently mutated in inflammation-associated colon tumors. These genes include senescence and TGFß-activin signaling genes. We find that TNFα can induce stemness and activate senescence signaling by enhancing cell plasticity in colonic epithelial cells, which could act as a selective pressure to mutate senescence-related genes in inflammation-associated colonic tumors. Furthermore, we show the efficacy of the Cdk4/6 inhibitor in vivo for inflammation-associated colonic tumors. Finally, we functionally validate that Arhgap5 and Mecom are tumor suppressor genes, providing possible therapeutic targets for CRC. Thus, we demonstrate the importance of the inactivation of senescence pathways in CRC development and progression in an inflammatory microenvironment, which can help progress toward precision medicine.
