Abstract
Introduction A critical value (or panic value) is a laboratory test result that significantly deviates from the normal value and represents a potentially life-threatening condition requiring immediate action. Although notification of critical values by critical value list (CVL) is a well-established method, their contribution to mortality prediction is unclear. Methods A total of 335,430 clinical laboratory results from 92,673 patients from July 2018 to December 2019 were used. Data in the first 12 months were divided into two datasets at a ratio of 70:30, and a 7-day mortality prediction model by machine learning (eXtreme Gradient Boosting [XGB] decision tree) was created using stratified random undersampling data of the 70% dataset. Mortality predictions by the CVL and XGB model were validated using the remaining 30% of the data, as well as different 6-month datasets from July to December 2019. Results The true results which were the sum of correct predictions by the XGB model and CVL using the remaining 30% data were 61,535 and 61,024 tests, and the false results which were the sum of incorrect predictions were 5,492 and 6,003, respectively. Furthermore, the true results with the different datasets were 105,956 and 102,061 tests, and the false results were 6,052 and 9,947, respectively. The XGB model was significantly better than CVL (p < 0.001) in both datasets.The receiver operating characteristic-area under the curve values for the 30% and validation data by XGB were 0.9807 and 0.9646, respectively, which were significantly higher than those by CVL (0.7549 and 0.7172, respectively). Conclusions Mortality prediction within 7 days by machine learning using numeric laboratory results was significantly better than that by conventional CVL. The results indicate that machine learning enables timely notification to healthcare providers and may be safer than prediction by conventional CVL.

Abstract
INTRODUCTION Contrast-induced nephropathy (CIN) caused by exposure to radioactive contrast media can cause acute kidney injury in patients with chronic kidney disease (CKD). We developed a multifaceted approach in a CIN-quality improvement (QI) program based on a shorter saline hydration protocol for the prevention of CIN in outpatients and assessed the effect of our CIN-QI program on decreasing both the incidence rate of CIN and overall use of contrast agents in patients undergoing contrast-enhanced computed tomography (CT). METHODS We conducted a multi-center prospective interrupted time-series study from 2006 to 2018 investigating the efficacy of a CIN- QI program in preventing CIN among outpatients with CKD. An automatic medical record system alert was implemented to instruct physicians to consult a nephrologist and administer prophylactic hydration and follow up when ordering contrast-enhanced imaging in patients with an estimated glomerular filtration rate (eGFR) < 45 mL/min/1.73 m2. The primary outcomes were the rates of prophylactic hydration and follow-up kidney function assessment and the incidence of CIN for eligible patients. The usage rate of contrast-enhanced CT was also examined. RESULTS A total of 95 594 patients who underwent contrast-enhanced CT were included in the study. The annual prophylactic hydration rate before the CIN-QI program ranged from 2.0% to 23.2% but increased to 59.2%-75.2% during the CIN-QI program (P < 0.001). The annual rate of follow-up kidney function testing also improved from 18.6%-25.8% to 34.1%-42.5% after implementation of the CIN-QI program (P < 0.001). The rate of CIN significantly declined in level by 10.0% at the start of the CIN-QI program (P = 0.002) and in trend by 2.9%/year (P < 0.001). The number of contrast-enhanced CT orders showed a positive level change in patients with advanced CKD, who were the CIN-QI program target group of patients with eGFR < 45 mL/min/1.73 m2, at the start of the implementation of the CIN-QI program. After implementing the CIN-QI program, the number of contrast-enhanced CT orders showed a negative trend change across all patients, which increased from -1.4%/year to -10.0%/year for patients with advanced CKD. CONCLUSION The multifaceted approach in the CIN-QI program may be associated with the decreased incidence of CIN and increased rates of prophylactic hydration and follow-up kidney function testing.

Abstract
Most cases of colorectal cancers (CRCs) are microsatellite stable (MSS), which frequently demonstrate lower response rates to immune checkpoint inhibitors (ICIs). RNA editing produces neoantigens by altering amino acid sequences. In this study, RNA editing was induced artificially by chemoradiation therapy (CRT) to generate neoantigens in MSS CRCs. Altogether, 543 CRC specimens were systematically analyzed, and the expression pattern of ADAR1 was investigated. In vitro and in vivo experiments were also performed. The RNA editing enzyme ADAR1 was upregulated in microsatellite instability-high CRCs, leading to their high affinity for ICIs. Although ADAR1 expression was low in MSS CRC, CRT including oxaliplatin (OX) treatment upregulated RNA editing levels by inducing ADAR1. Immunohistochemistry analyses showed the upregulation of ADAR1 in patients with CRC treated with CAPOX (capecitabine + OX) radiation therapy relative to ADAR1 expression in patients with CRC treated only by surgery (p < 0.001). Compared with other regimens, CRT with OX effectively induced RNA editing in MSS CRC cell lines (HT29 and Caco2, p < 0.001) via the induction of type 1 interferon-triggered ADAR1 expression. CRT with OX promoted the RNA editing of cyclin I, a neoantigen candidate. Neoantigens can be artificially induced by RNA editing via an OX-CRT regimen. CRT can promote proteomic diversity via RNA editing.

Abstract
BACKGROUND Prognosis of advanced gastrointestinal stromal tumors (GIST) refractory to tyrosine kinase inhibitors (TKIs) is poor. This randomized, placebo-controlled, phase 3 trial evaluated the efficacy and safety of pimitespib, a novel heat shock protein 90 inhibitor, in advanced GIST refractory to standard TKIs. PATIENTS AND METHODS Patients with histologically confirmed GIST refractory to imatinib, sunitinib, and regorafenib were randomized 2:1 to oral pimitespib 160 mg/day or placebo for five consecutive days per week in 21-day cycles. Following disease progression by blinded central radiological review (BCRR), crossover to open-label pimitespib was permitted. The primary endpoint was progression-free survival (PFS) by BCRR in the full analysis set. Secondary endpoints included overall survival (OS) adjusted using the rank preserving structural failure time method to reduce the expected confounding impact of crossover. RESULTS From Oct 31, 2018 to Apr 30, 2020, 86 patients were randomized to pimitespib (n=58) or placebo (n=28). Median PFS was 2.8 months (95% CI 1.6-2.9) with pimitespib versus 1.4 months (0.9-1.8) with placebo (hazard ratio [HR] 0.51 [95% CI 0.30-0.87]; one-sided p=0.006). Pimitespib showed an improvement in crossover-adjusted OS compared with placebo (HR 0.42 [0.21-0.85], one-sided p=0.007). Seventeen (60.7%) patients receiving placebo crossed-over to pimitespib; median PFS after crossover was 2.7 (95% CI 0.7-4.1) months. The most common (≥30%) treatment-related adverse events (AEs) with pimitespib were diarrhea (74.1%) and decreased appetite (31.0%); the most common (≥10%) grade ≥3 treatment-related AE was diarrhea (13.8%). Treatment-related AEs leading to pimitespib discontinuation occurred in 3 (5.2%) patients. CONCLUSION Pimitespib significantly improved PFS and crossover-adjusted OS compared with placebo and had an acceptable safety profile in patients with advanced GIST refractory to standard TKIs.

Abstract
Chemotherapy-induced nausea and vomiting (CINV) is one of the most serious adverse effects of cancer therapy. Cancer patients frequently use acid suppressants (AS) for palliation of gastrointestinal symptoms associated with malignancy and/or anticancer therapy. AS are suggested as an additional option for CINV management in several antiemetic guidelines, although their efficacy remains unknown. The aim of this study was to determine whether AS administration affects CINV incidence in cisplatin and gemcitabine treatment for biliary tract cancer. The primary endpoint was to evaluate whether AS administration was associated with the incidence of all-grade nausea in the first administration by logistic analysis. The secondary endpoints were to assess factors associated with anorexia. Prophylactic antiemetics were based on current guidelines. Nausea occurred in 34.2% of patients (grade 1, 31.7%; grade 2, 2.5%). Patients exhibiting vomiting and anorexia represented 4.2% and 39.1%, respectively, without grade 3/4 symptoms. Multivariate analysis suggested that the independent risk factors for nausea as female sex, and no- or less-alcohol drinking habit and regular narcotics administration were associated with anorexia. In contrast, AS administration was not associated with nausea and anorexia incidence (odds ratio, 95% confidence interval: 1.43, 0.64-3.23; P =0.38 for nausea, 1.62, 0.71-3.68; P =0.25 for anorexia). In conclusion, we found that AS administration is not associated with CINV incidence, and female sex is a risk factor for nausea, and non-alcohol drinking habits and regular narcotic use are factors associated with anorexia in cisplatin and gemcitabine treatment for biliary tract cancer. We should correctly administer AS depending on the patient's situation. Successful CINV management needs effective monitoring and administration of prophylactic antiemetics and counter-measure medicines for patients at risk.

Abstract
A rapid response system is required in a radiotherapy department for patients experiencing a critical event when access to an emergency department is poor due to geographic location and the patient is immobilised with a fixation device. We, therefore, rebuilt the response system and tested it through onsite simulations. A multidisciplinary core group was created and onsite simulations were conducted using a Plan-Do-Study-Act cycle. We identified the important characteristics of our facility, including its distance from the emergency department; the presence of many staff with little direct contact with patients; the treatment room environment and patient fixation with radiotherapy equipment. We also examined processes in each phase of the emergency response: detecting an emergency, calling the medical emergency team (MET), MET transportation to the site and on-site response and patient transportation to the emergency department. The protocol was modified, and equipment was updated. On-site simulations were held with and without explanation of the protocol and training scenario in advance. The time for the MET to arrive at the site during a 2017 simulation prior to the present project was 7 min, whereas the time to arrive after the first simulation session was shortened to 5 min and was then shortened further to 4 min in the second session, despite no prior explanation of the situation. A multidisciplinary project for emergency response with on-site simulations was conducted at an isolated radiation facility. A carefully planned emergency response is important not only in heavy ion therapy facilities but also in other departments and facilities that do not have easy access to hospital emergency departments.

Abstract
Background Evidence linking chronic kidney disease (CKD) and sleep duration is inconsistent. This study examined whether sleep duration is associated with a long-term risk of kidney function decline. Methods This retrospective, longitudinal cohort study included 82 001 participants who visited a primary care centre in Japan. Participants were categorized into CKD risk groups and sleep duration categories according to their self-reported average nightly sleep duration. The relationship between average nightly sleep duration and the incidence of composite renal outcome comprised a ≥40% reduction in estimated glomerular filtration rate (eGFR) from baseline and a decline in eGFR to <15 mL/min/1.73 m² was evaluated. Results The mean age and eGFR (±standard deviation) of the patient cohort were 45.8 (±12.4) years and 81.8 (±15.4) mL/min/1.73 m², respectively. A total of 41 891 participants (51.1%) were women. During the median follow-up of 5.1 years [interquartile range 2.2–9.6], 4214 (5.1%) participants achieved the composite renal outcome. Only the long and very long sleep durations (≥8 h/night) were associated with an increased incidence of the composite renal outcome compared with the reference duration (7 h/night) [adjusted odds ratio (OR) 1.22 and 1.44; 95% confidence interval (CI) 1.09–1.36 and 1.13–1.84, for long and very long sleep durations, respectively]. Furthermore, this association was significant for both long and very long sleep durations in the low CKD risk group but only for long sleep duration in the intermediate CKD risk group. The results of the sex-specific analysis showed that men had a decreased risk of achieving the composite renal outcome (OR 0.91; 95% CI 0.79–1.06), while there was an increased risk for women (OR 1.14; 95% CI 1.02–1.28). Conclusions Average sleep durations ≥8 h/night were associated with an increased incidence of poor renal outcomes over time. However, a longitudinal cohort study is required to confirm whether sleep duration can prevent poor renal outcomes.

Abstract
Abstract
Background
In Japan, forgoing life-sustaining treatment to respect the will of patients at the terminal stage is not stipulated by law. According to the Guidelines for the Decision-Making Process in Terminal-Stage Healthcare published by the Ministry of Health, Labor and Welfare in 2007, the Japanese Society for Dialysis Therapy (JSDT) developed a proposal that was limited to patients at the terminal stage and did not explicitly cover patients with dementia. This proposal for the shared decision-making process regarding the initiation and continuation of maintenance hemodialysis was published in 2014.
Methods and results
In response to changes in social conditions, the JSDT revised the proposal in 2020 to provide guidance for the process by which the healthcare team can provide the best healthcare management and care with respect to the patient's will through advance care planning and shared decision making. For all patients with end-stage kidney disease, including those at the nonterminal stage and those with dementia, the decision-making process includes conservative kidney management.
Conclusions
The proposal is based on consensus rather than evidence-based clinical practice guidelines. The healthcare team is therefore not guaranteed to be legally exempt if the patient dies after the policies in the proposal are implemented and must respond appropriately at the discretion of each institution.

Abstract
Acidemia is one of the risk factors for end-stage kidney disease and increases the mortality rate of patients with chronic kidney disease (CKD). Although urinary ammonium (U-NH4 + ) is the crucial component of renal acid excretion, U-NH4 + concentration is not routinely measured. To estimate U-NH4 + , urine osmolal gap (UOG = urine osmolality - [2(Na+ + K+ ) + urea + glucose]) is calculated and the formula (U-NH4 + = UOG/2) has traditionally been used. However, the usefulness of this formula is controversial in CKD patients. We assessed the relationship between U-NH4 + and UOG in patients with CKD. Blood and spot urine samples were collected in 36 patients who had non-dialysis-dependent CKD. The mean ± SD age of patients was 72.0 ± 14.8 years, and the mean ± SD serum creatinine and U-NH4 + were 2.7 ± 2.3 mg/dl and 9.3 ± 9.2 mmol/L, respectively. A significant relationship was found between UOG/2 and U-NH4 + (r = .925, p < .0001). U-NH4 + estimated using the UOG was on average higher by 4.7 mmol/L than the measured one. Our results suggested that UOG could be a useful tool in clinical settings, especially in patients with moderate to severe CKD.

Abstract
BACKGROUND Standard care for treating anemia in patients with CKD includes use of erythropoiesis-stimulating agents, which sometimes involves increased risks of cardiovascular morbidity and mortality. Previous studies in patients with anemia and nondialysis-dependent CKD (NDD-CKD) found significantly elevated hemoglobin levels with use of vadadustat, an oral hypoxia-inducible factor prolyl hydroxylase inhibitor, compared with placebo. METHODS In this phase 3, open-label, active-controlled noninferiority trial, we randomized 304 Japanese adults with anemia in NDD-CKD (including erythropoiesis-stimulating agent users and nonusers) to oral vadadustat or subcutaneous darbepoetin alfa for 52 weeks. The primary efficacy end point was average hemoglobin at weeks 20 and 24. Safety data included adverse events (AEs) and serious AEs. RESULTS A total of 151 participants received vadadustat and 153 received darbepoetin alfa. Least squares mean of the average hemoglobin at weeks 20 and 24 was 11.66 (95% confidence interval [95% CI], 11.49 to 11.84) g/dl for vadadustat and 11.93 (95% CI, 11.76 to 12.10) g/dl for darbepoetin alfa. The 95% CIs for both treatments were within the target hemoglobin range (11.0-13.0 g/dl), and the lower 95% confidence limit for the difference between groups (-0.50 g/dl) was above the predefined noninferiority margin (-0.75 g/dl), demonstrating noninferiority of vadadustat to darbepoetin alfa. Similar proportions of patients in each group reported AEs and serious AEs. The most frequent AEs with vadadustat were nasopharyngitis, diarrhea, and constipation. CONCLUSIONS In Japanese patients with NDD-CKD, vadadustat was noninferior to darbepoetin alfa, was effective up to week 52 in terms of average hemoglobin, and was generally well tolerated. These results suggest that vadadustat may be a potential treatment for anemia in this patient population.

Abstract
Hyperthermia has been used for cancer therapy for a long period of time, but has shown limited clinical efficacy. Induction-heating hyperthermia using the combination of magnetic nanoparticles (MNPs) and an alternating magnetic field (AMF), termed magnetic hyperthermia (MHT), has previously shown efficacy in an orthotopic mouse model of disseminated gastric cancer. In the present study, superparamagnetic iron oxide nanoparticles (SPIONs), a type of MNP, were conjugated with an anti-HER2 antibody, trastuzumab and termed anti-HER2-antibody-linked SPION nanoparticles (anti-HER2 SPIONs). Anti-HER2 SPIONs selectively targeted HER2-expressing cancer cells co-cultured along with normal fibroblasts and HER2-negative cancer cells and caused apoptosis only in the HER2-expressing individual cancer cells. The results of the present study show proof-of-concept of a novel hyperthermia technology, immuno-MHT for selective cancer therapy, that targets individual cancer cells.Abbreviations: AMF: alternating magnetic field; DDW: double distilled water; DMEM: Dulbecco's Modified Eagle's; Medium; f: frequency; FBS: fetal bovine serum; FITC: Fluorescein isothiocyanate; GFP: green fluorescent protein; H: amplitude; Hsp: heat shock protein; MHT: magnetic hyperthermia; MNPs: magnetic nanoparticles; PI: propidium iodide; RFP: red fluorescent protein; SPION: superparamagnetic iron oxide (Fe3O4) nanoparticle.

Abstract
Vadadustat is an oral hypoxia‐inducible factor prolyl hydroxylase inhibitor approved in Japan for the treatment of anemia in patients with chronic kidney disease (CKD). This phase 3, open‐label, single‐arm study evaluated the efficacy and safety of vadadustat in 24 Japanese patients with CKD‐associated anemia on hemodialysis who were not receiving erythropoiesis‐stimulating agents (ESAs). Patients received vadadustat for 24 weeks; the starting dose was 300 mg/day and doses were adjusted to achieve the target hemoglobin (Hb) range of 10.0–12.0 g/dL. The least squares mean of average Hb at Weeks 20 and 24 (95% confidence interval) was 10.75 g/dL (10.35, 11.14). The most common adverse event was shunt stenosis (25.0%). Adverse drug reactions (diarrhea and vomiting) occurred in two patients (8.3%) and the severity was mild. Vadadustat increased and maintained Hb levels within the target range and was generally well‐tolerated in Japanese patients with anemia on hemodialysis not receiving ESAs.

Abstract
Background Nivolumab (NIVO) and irinotecan (IRI) are standard treatments for refractory advanced gastric cancer (AGC); however, it is unclear which drug should be administered first or in which cases. The tumor growth rate (TGR) during preceding treatment is reported to be associated with tumor response in metastatic colorectal cancer patients treated with regorafenib or trifluridine/tipiracil, suggesting that TGR may be useful for drug selection. Therefore, we evaluated the association between TGR during preceding treatment and the tumor response to NIVO or IRI. Patients and methods We retrospectively evaluated consecutive AGC patients treated with NIVO or IRI and divided them into slow-growing (Slow) and rapid-growing (Rapid) groups according to TGR and the presence or absence of new lesions (NL+/NL−, respectively) during preceding treatment (Slow group: NL− with low TGR <0.30%/day; Rapid group: NL+ or high TGR ≥0.30%/day). Results A total of 117 patients (Rapid/Slow groups, 72/45; NIVO/IRI groups, 32/85) were eligible. All baseline characteristics except peritoneal metastases were similar between patients treated with NIVO and IRI in the Rapid and Slow groups. The response rate was significantly higher in patients treated with NIVO compared with IRI [31%/3%; odds ratio (OR), 13.8; P = 0.01; adjusted OR, 52; P = 0.002] in the Slow group, but there was no difference between patients treated with NIVO and IRI (5%/8%; OR, 0.68; P = 0.73; adjusted OR, 0.94; P = 0.96) in the Rapid group. Disease control rate, progression-free survival, and overall survival were consistent with these results. Conclusions Our findings suggest that NIVO treatment is a more favorable option for patients with slow-growing tumors, and NIVO and IRI are similarly recommended for patients with rapid-growing tumors in refractory AGC. TGR and NL emergence during preceding treatment may be helpful for drug selection and warrant further investigation. NIVO and IRI are standard treatments for refractory AGC, although it is unclear which should be administered first. TGR may be useful for drug selection, therefore we evaluated the association between TGR and the tumor response to NIVO or IRI. In the Slow group, the response rate (RR) was significantly higher in patients treated with NIVO compared with IRI. In the Rapid group, there was no significant difference in RR between the NIVO and IRI groups. TGR and NL emergence during preceding treatment may be useful for drug selection.

Abstract
Background Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor that stimulates erythropoiesis. Methods The efficacy and safety of vadadustat, compared with darbepoetin alfa, was determined in a Phase 3 double-blind study in Japanese anemic patients on hemodialysis. Patients receiving erythropoiesis-stimulating agents (ESAs) were randomized and switched to either vadadustat or darbepoetin alfa for 52 weeks. Doses were adjusted to maintain a hemoglobin (Hb) level of 10.0–12.0 g/dL. The primary endpoint was average Hb level at Weeks 20 and 24. Results Of the 323 randomized patients, 120 and 135 completed the 52-week treatment period in the vadadustat and darbepoetin alfa groups, respectively. The average Hb levels at Weeks 20 and 24 [least square mean (LSM) and 95% confidence interval (CI)] were 10.61 (10.45–10.76) and 10.65 (10.50–10.80) g/dL in the vadadustat and darbepoetin alfa groups, respectively, demonstrating vadadustat’s noninferiority to darbepoetin alfa (difference: −0.05 g/dL; 95% CI −0.26 to 0.17). In both groups, the mean Hb levels were maintained within the target range for 52 weeks. Furthermore, irrespective of patient backgrounds, the LSMs of Hb at Week 52 were within the target range. The most common adverse events were nasopharyngitis, diarrhea and shunt stenosis, which occurred at similar frequencies in both groups. No new safety concerns were identified. Conclusions Vadadustat was as well-tolerated and effective as darbepoetin alfa in maintaining Hb levels within the target range. The findings suggest that vadadustat can be an alternative to ESA in the management of anemia in Japanese hemodialysis patients receiving ESA (ClinicalTrials.gov, NCT03439137).

Abstract
Background: The phase II J003 (N = 169) and phase III RECOURSE (N = 800) trials demonstrated a significant improvement in survival with trifluridine (FTD)/tipiracil (TPI) versus placebo in patients with refractory metastatic colorectal cancer. This post hoc analysis investigated pharmacokinetic data of FTD/TPI exposure and pharmacodynamic markers, such as chemotherapy-induced neutropenia (CIN) and clinical outcomes. Patients and methods: A total of 210 patients from RECOURSE were enrolled in this substudy. A limited sampling approach was used, with three pharmacokinetic samples drawn on day 12 of cycle 1. Patients were categorized as being above or below the median area under the plasma concentration–time curve (AUC) for FTD and TPI. We conducted a post hoc analysis using the entire RECOURSE population to determine the correlations between CIN and clinical outcome. We then carried out a similar analysis on the J003 trial to validate the results. Results: In the RECOURSE subset, patients in the high FTD AUC group had a significantly increased CIN risk. Analyses of the entire population demonstrated that FTD/TPI-treated patients with CIN of any grade in cycles 1 and 2 had significantly longer median overall survival (OS) and progression-free survival (PFS) than patients who did not develop CIN and patients in the placebo group. Patients who required an FTD/TPI treatment delay had increased OS and PFS versus those in the placebo group and those who did not develop CIN. Similar results were obtained in the J003 cohort. Conclusions: In RECOURSE, patients with higher FTD drug exposure had an increased CIN risk. FTD/TPI-treated patients who developed CIN had improved OS and PFS versus those in the placebo group and those who did not develop CIN. Similar findings were reported in the J003 cohort, thus validating the RECOURSE results. The occurrence of CIN may be a useful predictor of treatment outcomes for FTD/TPI-treated patients.

Abstract
Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor for the treatment of anemia in patients with chronic kidney disease (CKD). This phase 3, open-label, 24-week single-arm study evaluated the efficacy and safety of vadadustat in 42 Japanese CKD patients with anemia undergoing peritoneal dialysis. Patients received oral vadadustat for 24 weeks, initiated at 300 mg/day and doses were adjusted to achieve the target hemoglobin (Hb) range of 11.0-13.0 g/dL. Least squares mean of average Hb at weeks 20 and 24 was 11.35 g/dL, which was within the target range. The most frequent adverse events were catheter site infections (23.8%), which were not related to vadadustat treatment. Vadadustat was generally well tolerated and effective in controlling Hb levels within the target range, indicating the usefulness of vadadustat for treating anemia in Japanese CKD patients undergoing peritoneal dialysis.

Abstract
Abstract
Background
Catheter ablation of LV summit VT can be challenging due to possible subepicardial or intramural site of origin and its close proximity to the major coronary vessels.
Objective
Local electrograms monitoring inside LV summit communicating vein potentially defines arrhythmogenic substrates and facilitates ablation from the adjacent anatomical structures.
Results
We experienced two cases of LV summit VT with epicardial local abnormal ventricular activities (Epi-LAVA) recorded from distal bipolar electrode of the 2F microcatheter in communicating vein close to the superior portion of LV summit. During sinus rhythm, Epi-LAVA displayed isolated late fractionated potentials in the first case but had initial fractionated potentials fused with terminal portion of far-field ventricular signals and late isolated potentials exhibiting 2:1 conduction in the second case. Epi-LAVA represented earliest ventricular signals during VT in both cases. Pace mapping at Epi-LAVA sites yielded single QRS morphology with excellent pacemap score and induced VT. Our strategy was to perform ablation at the facing site of Epi-LAVA aiming to eliminate the potentials transmurally. Radiofrequency (RF) energy was applied above and under the left coronary cusp opposite to Epi-LAVA sites using 3.5-mm tip open-irrigation catheter with a power of 30–35 W for 60 seconds under real-time intracardiac echocardiograhic guidance. VT was slowed and terminated in 1 second. Repeat ablation delayed and completely abolished Epi-LAVA followed by noninducibility of VT. Anatomical proximity of the left coronary cusp semilunar insertion and subepicardial or intramural site of origin possibly dictates successful ablation. Epi-LAVA from coronary vein mapping serve as a new landmark of the ablation target with a measurable procedural endpoint.
Conclusion
Elimination of epicardial substrates with RF energy application at the left coronary cusp can be a novel strategy for LV summit VT ablation.

Abstract
BACKGROUND Chronic kidney disease (CKD) is known to be associated with cancer mortality. However, no study has considered the well-known cancer prognostic factors, ECOG Performance Status (PS) and cancer treatment, as confounding factors. We assessed the independent relationship between CKD and cancer death in stage IV cancer patients. METHODS In this retrospective observational study, we included stage IV cancer patients diagnosed from 2009 to 2014 in a single center. We collected baseline clinical and laboratory variables, and cancer-specific variables, and assessed the presence of CKD. Our primary outcome was all-cause mortality. The secondary outcome was cancer-specific mortality and site-specific cancer mortality. RESULTS Among 961 eligible stage IV cancer patients (median age 69 years, 51.8% male), 150 patients had CKD. During follow-up (median 9.8 months), 638 patients died, of whom 526 patients died from cancer. After adjusting for prognostic variables, including ECOG PS and cancer treatment, all-cause mortality and cancer-specific mortality were significantly higher in CKD patients than in non-CKD patients (HR 1.41, 95% CI 1.13-1.77 and HR 1.43, 95% CI 1.12-1.83, respectively). In patients with breast and kidney and urinary tract cancers, CKD was associated with a significantly increased risk of death (HR 7.01, 95% CI 1.47-33.4 and HR 3.33, 95% CI 1.42-7.78, respectively). CONCLUSIONS CKD at the time of stage IV cancer diagnosis was associated with all-cause mortality and cancer-specific mortality. Moreover, the association between CKD and cancer-specific death was site specific for breast cancer and kidney and urinary tract cancer.

Abstract
Background Increasing fill volume is an effective means of improving clearances in patients on peritoneal dialysis (PD). Since Japanese PD patients are physically smaller than their Western counterparts, there is some concern that PD patients in Japan may be unable to tolerate larger fill volumes. Objective To determine patient tolerance and changes in solute clearance and net ultrafiltration resulting from increased fill volumes in Japanese patients on PD. Design Prospective double-blind study, randomizing patients to three different fill volumes (2.5% dextrose solution: 1.5 L, 2.0 L, or 2.5 L) administered in random order on three different occasions separated by 1 week. Results Twenty-one patients with a mean age of 55.4 ± 2.1 years and a mean body surface area of 1.66 ± 0.03 m2 were studied. On a scale of 0 to 10, patients’ mean discomfort scores were 2.14 ± 0.59, 3.48 ± 0.54, and 3.81 ± 0.63 ( p = 0.047) at the end of the 1.5-L, 2.0-L, and 2.5-L dwells, respectively. There were no reports of cramps or shortness of breath with any fill volume. Patients were able to correctly guess the actual fill volume for only 34 of the 63 total exchanges (54.0%). Increasing fill volume resulted in an incremental improvement in peritoneal creatinine clearance, from 3.74 ± 0.16 to 4.49 ± 0.21 ( p < 0.001, 2.0 L vs 1.5 L) to 5.12 ± 0.20 mL/minute ( p < 0.001, 2.5 L vs 2.0 L) for 1.5-L, 2.0-L, and 2.5-L dwells, respectively. Peritoneal urea clearance also increased significantly, from 5.65 ± 0.13 to 7.04 ± 0.17 ( p < 0.001, 2.0 L vs 1.5 L) and 8.16 ± 0.29 mL/minute ( p < 0.001, 2.5 L vs 2.0 L), with incremental increases in fill volume. Similarly, net ultrafiltration in a 4-hour dwell increased significantly with fill volume, from 255.24 ± 24 mL with 1.5 L, to 356 ± 24 ( p < 0.004, 2.0 L vs 1.5 L) and 392 ± 29 mL ( p < 0.086, 2.5 L vs 2.0 L) in patients receiving 2.0 L and 2.5 L, respectively. Conclusion Increasing the fill volume results in improvement in solute clearance and net ultrafiltration in Japanese PD patients, with minimal increase in patient discomfort. A large percentage of patients were unable to identify the actual fill volume.
