Abstract
Abstract
Background
Pulmonary vein isolation (PVI) using radiofrequency (RF) or cryoballoon (CB) has been an established treatment for atrial fibrillation. PVI using RF is the most common method with a rather complex technique of a point-by-point tissue heating and navigation of electro-anatomical-guided mapping system, and PVI with CB is also the common method with a relatively simple technique of freezing balloon occlusion. These 2 types of ablation are comparable in terms of the efficacy of the PVI procedure.
Purpose
The data on the clinical outcome of each AF type with PV triggers has been limited. We compared the outcome of success rate between RF and CB group with respect to each AF type, and further assessed the efficacy of pulmonary vein isolation for AF patients with the origin of only PV.
Methods
A total of 3402 AF patients (age 64±11; 2463 males) underwent initial PVI from May 2009 to July 2018 (PAF: 67%, non-PAF: 37%). Radiofrequency using irrigation-tip catheter was employed to 1796 patients since May 2009 (RF-PAF: 55%, RF-non-PAF: 45%). Second-generation cryoballoon was employed to other 1606 patients since September 2014 (CB-PAF: 81%, CB-non-PAF: 19%). In CB group, PV touch-up ablation with RF was needed for 113 patients (7%) (CB-PAF: 6%, CB-non-PAF: 13%; p<0.001). After PVI, additional ablation for non-PV foci was undergone after the induction by using isoproterenol infusion and rapid atrial pacing (RF-AF: 34%, CB-AF: 32%; p=0.107).
Results
In all PAF patients, AF free survival rate was significantly superior in CB group (2-years Kaplan-Meir event rate, CB 83.2%, RF 75.2%; log-rank p<0.001). The percentage of patients with non-PV foci was almost equivalent in both group (CB 30%, RF 31%, p=0.644). And in PAF patients with only PV-foci, AF free survival rate was significantly superior in CB group (2-years Kaplan-Meir event rate, CB 85.0%, RF 78.8%; log-rank p<0.001). On the other hand, in all non-PAF patients, AF free survival rate was almost equivalent in both non-PAF group (2-years Kaplan-Meir event rate, CB 65.5%, RF-non-PAF 70.0%; log-rank p=0.9). The percentage of patients with non-PV foci was almost equivalent in both group (CB 40%, RF 39%, p=0.731), And in non-PAF patients with only PV-foci, AF free survival rate was almost equivalent in both non-PAF group (2-years Kaplan-Meir event rate, CB 69.7%, RF 73.0%; log-rank p=0.376).
Conclusions
Our study showed better outcome of PVI with CB for PAF patients with PV triggers, and indicated the non-inferiority of PVI with CB for non-PAF patients with PV triggers to PVI with RF.

Abstract
Abstract
Background
Some studies reported that performing coronary angiography (CAG) for patients with out-of-hospital cardiac arrest (OHCA) is effective for the prognosis and neurological outcome. However, the impact of complexity of coronary artery disease (CAD) on CAG findings has not been evaluated sufficiently.
Purpose
We sought to investigate the complexity of CAD to predict the prognosis and neurological outcome in patients with OHCA.
Methods
A total of 1382 out-of-hospital cardiac arrest patients were transferred to our critical care center, of which 252 cardiovascular arrest patients achieving the return of spontaneous circulation (ROSC) were extracted from the institutional consecutive database between January 2015 and December 2018. Among those patients, we performed CAG for 160 patients. To predict mortality in hospital and neurological outcome at 30 days, we investigated basic patients' characteristics, pre-hospital information, coronary anatomical angiographical findings.
Results
Ventricular fibrillation (VF) (P=0.001), younger age (P=0.007), pre-hospital ROSC (P<0.001) and normal coronary artery on CAG findings (P=0.014) were associated with low 30-days mortality in hospital. VF (P=0.003), younger age (P=0.004), pre-hospital ROSC (P<0.001), bystander cardiopulmonary resuscitation (CPR) (P=0.043) and normal coronary artery (P=0.001) were associated with good neurological outcome (cerebral-performance-category (CPC) =1 or 2) at 30 days. We further investigated 100 patients who had any coronary artery stenosis on CAG findings. Among these patients, 55 patients (55.0%) had multi-vessel coronary artery disease and 29 patients (29.0%) had at least a chronic total occlusion lesion. VF survivor (P=0.035), without previous history of CAD (P=0.008), pre-hospital ROSC (P=0.013), and Syntax score (P=0.002) were associated with low 30-days mortality. In multivariate analysis, Syntax score (OR 0.94; 95% confidence interval (CI) 0.88–0.99; P=0.042) was independent predictor of mortality. Bystander CPR (P=0.001), pre-hospital ROSC (P<0.001) were associated with good neurological outcome at 30 days. Bystander CPR (OR 5.92; 95% CI 2.01–17.5; P<0.001) and pre-hospital ROSC (OR 9.22; 95% CI 3.34–25.5; P<0.001) were predictive for good neurological outcome.
Conclusions
OHCA patients with any coronary stenosis had high mortality and bad neurological outcome in comparison with those who had normal coronary arteries. OHCA patients with CAD had complex lesions such as multi-vessel disease or chronic total occlusion lesions. The coronary complexity in patients with OHCA was a predictor of in-hospital 30-days mortality. However, pre-hospital care such as bystander CPR and pre-hospital ROSC were the most important to achieve good neurological outcome at 30 days in the present study.

Abstract
Abstract
Background
The prognosis of patients with out-of-hospital cardiac arrest (OHCA) remains poor. Coronary artery disease (CAD) is the most frequent cause of OHCA. The prompt evaluation and revascularization for coronary artery in OHCA patients with ST-segment elevation are recommended because they often have CAD. However, OHCA patients without ST-segment elevation also have any coronary stenosis in the non-negligible proportion. The predictor of mortality and neurological outcome in OHCA patients with no ST-segment elevation has not been sufficiently elucidated.
Purpose
We sought to investigate the predictor of mortality and neurological outcome at 30 days in OHCA patients without ST-segment elevation.
Methods
A total of 1382 out-of-hospital cardiac arrest patients were transferred to our critical care center, of which 252 cardiovascular arrest patients achieving the return of spontaneous circulation (ROSC) were extracted from the institutional consecutive database between January 2015 and December 2018. Among those patients, 183 patients' electrocardiogram after ROSC were without ST-segment elevation. We performed coronary angiography (CAG) for 103 patients, who were eligible for final analysis. To predict mortality in hospital and neurological outcome at 30 days, we investigated basic patients' characteristics, pre-hospital information, post-hospital care.
Results
Any coronary stenosis was founded in 50 patients (48.5%). Male (P=0.007), older age (P<0.001), past history of coronary artery disease (CAD) (P=0.037) and diabetes mellitus (P=0.087) were associated with coronary artery stenosis on CAG findings. Age (OR 1.05; 95% confidence interval (CI) 1.02–1.08; P<0.001), male (OR 5.33; 95% CI 1.37–20.7; P<0.001) were independent predictors of coronary artery stenosis. Among those who had stenosis, 34 patients (68.0%) survived and 27 patients (54.0%) achieved good neurological outcome (cerebral-performance-category (CPC) =1 or 2) at 30 days. Successful revascularization by percutaneous coronary intervention (PCI) was not associated with low mortality (P=0.77). Past history of CAD (P=0.014) and high Syntax score (P=0.030) were associated with mortality. Bystander cardiopulmonary resuscitation (CPR) (P-0.021), pre-hospital ROSC (P<0.001) was more frequent in patients with good neurological outcome. Pre-hospital ROSC (OR 14.7; 95% CI 3.1–69.3; P<0.001) was independently predictive for good neurological outcome.
Conclusions
Successful PCI for OHCA patients with no ST-segment elevation was not a predictor of mortality. CAD past history and complex CAD was associated with mortality. Pre-hospital information such as pre-hospital ROSC was important to achieve good neurological outcome.

Abstract
Abstract
Background
Pulmonary vein isolation (PVI) using second generation cryoballoon (CB) ablation has become an established treatment for paroxysmal atrial fibrillation (PAF) patients. On the other hand, PVI with radiofrequency (RF) has been an established treatment for non-PAF patients, in addition to PAF patients.
Purpose
The data on second generation CB ablation for non-PAF patients is limited. We assessed the application of PVI with CB for non-PAF patients and compared the outcomes of success rate, radiational time, and procedural time.
Methods
A total of 2632 AF patients (age 64±10; 1873 males) underwent initial PVI from September 2014 to June 2018. Second-generation CB was employed to 1587 patients (CB-PAF: 80%, CB-non-PAF: 20%) and RF using irrigation-tip catheter was employed to other 1045 patients (RF-PAF: 40%, RF-non-PAF: 60%). In CB group, PV touch-up ablation with RF was needed for 113 patients (7%) (CB-PAF: 6%, CB-non-PAF: 13%; p<0.001). After PVI, additional ablation for non-PV foci was undergone after the induction by using ISP infusion and rapid atrial pacing.
Results
AF free survival rate was almost equivalent in both non-PAF group (2-years Kaplan-Meir event rate, CB-non-PAF 66.3%, RF-non-PAF 69.8%; log-rank p=0.297). There was significantly difference in procedural time (CB-non-PAF 132±56min, RF-non-PAF: 189±52min, p<0.001), and radiation time (CB-non-PAF: 47±40min, RF-non-PAF: 75±31min, p<0.001). The percentage of patients with non-PV foci was significantly higher in CB group (CB-non-PAF 41%, RF-non-PAF 54%, p<0.001), and after excluding the patients with non-PV foci, AF free survival rate was almost equivalent in both group (2-years Kaplan-Meier event rate, CB-non-PAF 75.4%, RF-non-PAF 78.8%; log-rank p=0.577). On the other hand, in patients in CB, AF free survival rate was significantly superior in PAF group (2-years Kaplan-Meir event rate, CB-PAF 83.3%, CB-non-PAF 65.2%; log-rank p<0.001). There was significantly difference in procedural time (CB-PAF: 117±47min, CB-non-PAF: 132±56min, p<0.001), and radiation time (CB-PAF: 38±22min, CB-non-PAF: 46±27min, p<0.001). The percentage of patients with non-PV foci was significantly higher in non-PAF group (CB-PAF 30%, CB-non-PAF 41%, p<0.001), and after excluding the patients with non-PV foci, AF free survival rate was also significantly superior in PAF group (2-years Kaplan-Meier event rate, CB-PAF 85.1%, CB-non-PAF 69.8%; log-rank p<0.001).
Conclusions
For non-PAF patients with PV triggers, PVI with CB might be non-inferior to PVI with RF. Our study showed the efficacy of CB in terms of the shortening of procedural time, and the reduction of radiational exposure. PVI with CB for non-PAF patients was inferior to that for PAF patients.

Abstract
A 7-year-old female suffering from syncope attacks and deafness was genetically diagnosed with Jervell and Lange-Nielsen syndrome (JLNS). A transvenous-designed shock lead and implantable cardioverter-defibrillator (ICD) were atypically implanted subcutaneously, because the patient's body was small. Six years after implantation, we confirmed the patient's eligibility for a subcutaneous ICD (S-ICD) based on electrocardiogram screening. The implanted ICD system was replaced with a new standard S-ICD system. Implantation of the S-ICD may be considered a reliable and safe option in young patients with JLNS, even if their electrocardiograms show remarkable prolongation of the QT interval and T-wave alternans.

Abstract
SETTING The number of patients with non-tuberculous mycobacterial lung disease (NTM-LD) worldwide has been increasing. Mycobacterium avium complex lung disease (MAC-LD) accounts for 90% of NTM-LD. MAC-LD necessitates long-term treatment, but adverse reactions with long-term administration of drugs are poorly understood. OBJECTIVE To evaluate adverse reactions with long-term administration of drugs for MAC-LD. DESIGN We conducted a retrospective single-centre medical chart review of 364 patients administered two or more drugs between July 2010 and June 2015. RESULTS The prevalence and median time to onset of adverse reactions were as follows: hepatotoxicity 19.5%, 55 days; leucocytopaenia 20.0%, 41 days; thrombocytopaenia 28.6%, 61.5 days; cutaneous reactions 9.3%, 30 days; ocular toxicity 7.7%, 278 days; and increase in serum creatinine 12.4%, 430.5 days. Multivariate analysis showed that rifampicin use was independently associated with thrombocytopaenia, and ethambutol use was independently associated with increases in serum creatinine. CONCLUSION The main adverse reactions appeared within 3 months after start of treatment. Most patients were able to continue treatment with liver-supporting therapy, antihistamine agents or desensitisation therapy; however, ocular toxicity must be monitored for up to 1 year after start of treatment.

Abstract
Andersen-Tawil syndrome (ATS) is an inherited disorder characterised by the triad of ventricular arrhythmias (VAs), periodic paralysis and dysmorphic features. A 31-year-old woman diagnosed with ATS caused by a KCNJ2 mutation (p.R228ins) was urgently admitted to our hospital following an episode of syncope during exercise. Electrocardiography revealed frequent premature ventricular complexes and non-sustained ventricular tachycardias (VTs) with pleomorphic QRS patterns. During the intravenous flecainide test (30 mg), the frequent VAs were inhibited completely. After oral flecainide (100 mg) was started, VAs, except for a brief bigeminy, were suppressed during the exercise test. On 24-hour Holter recordings, the VAs decreased from 50 133 to 13 363 beats/day (-73%). Sustained VT and syncope were not observed during a 3-year follow-up period. Intravenous flecainide challenge test may be useful in predicting the efficacy of oral flecainide treatment for patients with ATS.

Abstract
Background Combination therapy with oral fluoropyrimidine and irinotecan has not yet been established as first-line treatment of metastatic colorectal cancer (mCRC). We carried out a randomized, open-label, phase III trial to determine whether S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab in terms of progression-free survival (PFS). Patients and methods Patients from 53 institutions who had previously untreated mCRC were randomly assigned (1 : 1) to receive either mFOLFOX6 or CapeOX plus bevacizumab (control group) or S-1 and irinotecan plus bevacizumab (experimental group; a 3-week regimen: intravenous infusions of irinotecan 150 mg/m2 and bevacizumab 7.5 mg/kg on day 1, oral S-1 80 mg/m2 twice daily for 2 weeks, followed by a 1-week rest; or a 4-week regimen: irinotecan 100 mg/m2 and bevacizumab 5 mg/kg on days 1 and 15, S-1 80 mg/m2 twice daily for 2 weeks, followed by a 2-week rest). The primary end point was PFS. The noninferiority margin was 1.25; noninferiority would be established if the upper limit of the 95% confidence interval (CI) for the hazard ratio (HR) of the control group versus the experimental group was less than this margin. Result Between June 2012 and September 2014, 487 patients underwent randomization. Two hundred and forty-three patients assigned to the control group and 241 assigned to the experimental group were included in the primary analysis. Median PFS was 10.8 months (95% CI 9.6-11.6) in the control group and 14.0 months (95% CI 12.4-15.5) in the experimental group (HR 0.84, 95% CI 0.70-1.02; P < 0.0001 for noninferiority, P = 0.0815 for superiority). One hundred and fifty-seven patients (64.9%) in the control group and 140 (58.6%) in the experimental group had adverse events of grade 3 or higher. Conclusion S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab with respect to PFS as first-line treatment of mCRC and could be a new standard treatment. Clinical trials number UMIN000007834.

Abstract
Chronic kidney disease (CKD) is a common condition among elderly patients and has been reported to be a biomarker for the presence of malignant disease. In addition, unfavorable outcomes for patients with upper tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy can be due to independent clinical factors. Therefore, the present study analyzed the clinicopathological data of patients with UTUC, who underwent radical nephroureterectomy at our institution, to clarify whether preoperative CKD and other factors are independent predictors of the shorter disease-specific and/or recurrence-free survival time of these patients. A retrospective review of 187 patients who underwent radical nephroureterectomy was conducted, and patients were followed for at least 3 months postoperatively. The clinicopathological factors that are thought to have potentially significant roles in the progression and metastasis of malignant tumors and for disease-specific and recurrence-free survival were evaluated. Positive surgical margins and an estimation of the glomerular filtration rate (eGFR) of <60 were independent factors for the shorter disease-specific survival time in multivariate analysis with Cox's proportional hazards model [hazard ratio (HR), 2.401: 95% confidence interval (CI), 1.044-5.255; and HR, 2.371: 95% CI, 1.024-5.898, respectively]. Another multivariate analysis also revealed that positive surgical margins (HR, 4.477; 95% CI, 2.042-9.469), and preoperative eGFR <60 (HR, 2.362; 95% CI, 1.067-5.592) were independent factors for the worse recurrence-free survival rate in all patients. Patients with UTUC who had eGFR <60 as well as positive surgical margins had significantly shorter time to disease-specific mortality and extraurothelial recurrence. The present study demonstrated that patients with UTUC undergoing radical nephroureterectomy who have CKD as well as positive surgical margins should be carefully followed up postoperatively.

Abstract
Panobinostat, a histone deacetylase inhibitor, induces histone acetylation and acts against cancer but attenuates its anticancer activity by activating the mammalian target of rapamycin (mTOR) pathway. AMP-activated protein kinase (AMPK) is a cellular energy sensor that reportedly inhibits the mTOR pathway. The antidiabetic drug metformin is also a potent AMPK activator and we investigated whether it augmented panobinostat's antineoplastic activity in bladder cancer cells (UMUC3, J82, T24 and MBT-2). Metformin enhanced panobinostat-induced apoptosis and the combination inhibited the growth of bladder cancer cells cooperatively in vitro and in vivo. As expected, metformin increased the phosphorylation of AMPK and decreased the panobinostat-caused phosphorylation of S6 ribosomal protein, thus inhibiting the panobinostat-activated mTOR pathway. The AMPK activation was shown to play a pivotal role in the combination's action because the AMPK inhibitor compound C attenuated the combination's anticancer activity. Furthermore, the AMPK activation by metformin enhanced panobinostat-induced histone and non-histone acetylation. This acetylation was especially remarkable in the proteins in the detergent-insoluble fraction, which would be expected if the combination also induced endoplasmic reticulum stress.

Abstract
Abstract
Background
Several studies showed that first-line bevacizumab plus chemotherapy for HER2-negative metastatic breast cancer improves progression-free survival and tumor response rate but not overall survival. MERiDiAN trial evaluated plasma vascular endothelial growth factor-A (VEGF-A) prospectively as a predictive biomarker for bevacizumab efficacy in metastatic breast cancer. However, results of this trial do not support using baseline plasma VEGF-A to identify patients benefitting most from bevacizumab. We measured baseline serum VEGF-A level from stored blood samples of metastatic breast cancer patient with treated bevacizumab plus paclitaxel as fist-line and later line therapy, and evaluated a correlation between serum VEGF-A level and efficacy of bevacizumab and prognosis of breast cancer patients tread with bevacizumab, retrospectively.
Patients and methods
We examined blood samples from 57 metastatic breast cancer patients treated with bevacizumab and paclitaxel, after obtaining written informed consent. And, we evaluated a correlation between baseline serum VEGF-A level and time to treatment failure (TTF) and overall survival (OS). We also compared the serum VEGF-A level of response group (CR and PR) and that of non-response group (SD and PD).
Results
Baseline serum level of VEGF-A ranged from 80 to 2079 pg/ml. Cases of treatment line were as follows: first-line, 22 cases (38.6%); second line, 11 cases (19.3%) and third-line and the later line, 24 cases (42.1%). The cutoff identified by ROC curve analysis that was able to differentiate response group and non-response group in first-line setting was 360pg/ml for serum VEGF-A. And, we separated high serum VGEF-A group and low serum VEGF-A group of patients treated with bevacizumab plus paclitaxel.
In patients treated as first line therapy, median TTF was 4.0 months with high serum VGEF-A group versus 5.0 months with low serum VEGF-A group, and median OS was 12 months with high serum VGEF-A group versus 11months with low serum VEGF-A group. There were no significant differences in both TTF and OS in first line setting. In patients treated as second line and later line therapy, median TTF was 2.8 months with high serum VGEF-A group versus 7.1 months with low serum VEGF-A group, and median OS was 6.4 months with high serum VGEF-A group versus 12.7 months with low serum VEGF-A group. The prognosis of high serum VEGF-A group was significantly worse than that of low serum group in both TTF and OS.
The serum VEGF-A level of response group was tend to be higher than that of non-response group in first line setting, and was lower in second and later line setting. However, there were no significant differences.
Conclusion
In this study, serum VEGF-A cannot be a predictor for efficacy of bevacizumab plus paclitaxel as first line therapy for metastatic breast cancer patients. On the other hand, there was a possibility that high serum level of VEGF-A can be a poor prognostic factor in late line therapy setting of bevacizumab.

Abstract
Abstract
Background
Visceral obesity is one of the risk factors for clinically relevant pancreatic fistula after pancreatic resection. The objective of this study was to evaluate the impact of intraperitoneal lipolysis on postoperative pancreatic fistula.
Methods
The degree of intraperitoneal lipolysis was investigated by measuring the free fatty acid concentration in drain discharge in patients after pancreatic resection. An experimental pancreatic fistula model was prepared by pancreatic transection, and the impact of intraperitoneal lipolysis was evaluated by intraperitoneal administration of triolein (triglyceride) with, or without orlistat (lipase inhibitor).
Results
Thirty-three patients were included in the analysis. The free fatty acid concentration in drain discharge on postoperative day 1 was significantly associated with the development of a clinically relevant pancreatic fistula (P = 0·004). A higher free fatty acid concentration in drain discharge was associated with more visceral adipose tissue (P = 0·009). In the experimental model that included 98 rats, intraperitoneal lipolysis caused an increased amount of pancreatic juice leakage and multiple organ dysfunction. Intraperitoneal administration of a lipase inhibitor reduced lipolysis and prevented deterioration of the fistula.
Conclusion
Intraperitoneal lipolysis significantly exacerbates pancreatic fistula after pancreatic resection. Inhibition of lipolysis by intraperitoneal administration of a lipase inhibitor could be a promising therapy to reduce clinically relevant postoperative pancreatic fistula.

Abstract
A 60-year-old female with premature ventricular contractions (PVCs) originating from the bottom of the posteromedial papillary muscle of the left ventricle underwent radiofrequency catheter ablation (RFCA) using an irrigated-tip catheter. During ablation of the PVCs, a loud steam pop was observed. Intracardiac echocardiography (ICE) revealed a growing, hyperechogenic intramyocardial microbubble formation around the catheter tip. The formation disappeared slowly and completely, leaving an endocardial laceration without pericardial effusion. ICE imaging is valuable during a difficult RFCA procedure, because ICE reveals the exact anatomical position of the catheter and thus allows rapid evaluation of the occurrence of steam popping and any possible subsequent complication.

Abstract
INTRODUCTION Early repolarization syndrome is a recently proposed condition characterized by an early repolarization pattern in the electrocardiogram (ECG) and ventricular fibrillation in the absence of structural heart abnormalities. Although some studies have suggested that early repolarization is associated with frequency of atrial fibrillation, the association of early repolarization with atrial fibrillation is not well known. HYPOTHESIS Early repolarization indicates the substrate for atrial fibrillation in addition to that for ventricular fibrillation. METHOD This study included 79 patients (57 men [72%]; age, 45 ± 12 years) aged less than 60 years who had paroxysmal lone atrial fibrillation and 395 age- and sex-matched healthy controls (patient:control ratio, 1:5). Patients who had structural heart disease, hypertension, diabetes, hyperthyroidism, history of successful resuscitation, or the Brugada type ECG were excluded. ECGs recorded during sinus rhythm were compared between patients with atrial fibrillation and healthy controls. RESULTS Early repolarization in the inferior and/or lateral leads was more common in patients with atrial fibrillation (25%) than controls (10%; P = 0.001). The location and magnitude of early repolarization were similar between the two groups. Other electrocardiographic measurements were not different between the two groups. Among patients with atrial fibrillation, there was no difference in clinical characteristics including age at atrial fibrillation development, sex, and body mass index between patients with early repolarization and those without early repolarization. Electrocardiographic measurements were not different between patients with early repolarization and those without early repolarization. CONCLUSION Early repolarization was associated with lone atrial fibrillation. Early repolarization may indicate increased susceptibility to atrial fibrillation.

Abstract
AIM Phase angle (PhA) can be determined through bioelectrical impedance analysis and is a unique variable for skeletal muscle. The objective of this study was to evaluate the relationship between PhA and muscle mass/quality in older adults. In addition, we attempted to determine the cutoff value of PhA for poor muscle function. METHODS Community-dwelling Japanese older men (n=285, 81.1±7.1 years) and women (n=724, 80.4±6.8 years) participated in this study and were classified into four groups based on the Asian Working Group for Sarcopenia (normal, presarcopenia, dynapenia, and sarcopenia). We measured PhA using bioelectrical impedance analysis, muscle quantity and quality indicators using ultrasonography, muscle strength, and physical performance and compared them in four groups. We also tried to determine the cutoff value of PhA for poor muscle function. RESULTS We found a significant difference in PhA among the four groups in men (P<0.05), and the dynapenia (3.61±0.75°) and sarcopenia groups (3.40±0.74°) showed significantly lower values than the normal group (4.50±0.86°) (P<0.05), but not the presarcopenia group (4.12±0.85°). In women, a significant difference was also observed among the four groups (P<0.05), and the dynapenia (3.41±0.65°) and sarcopenia groups (3.31±0.66°) showed significantly lower measures than the normal group (4.14±0.71°) (P<0.05), but not the presarcopenia group (4.07±0.51°). The receiver-operating characteristic curve analysis indicated the best cutoff value of PhA (men: 4.05°, women: 3.55°) to discriminate sarcopenia and dynapenia from normal and presarcopenia. CONCLUSION These findings suggest that PhA is a useful indicator for muscle function.

Abstract
BACKGROUND/AIM In the present study, the antineoplastic activity and mechanism of action of phenoxodiol, a novel isoflavone analog, was investigated in renal cancer cells. MATERIALS AND METHODS A panel of renal cancer cells (769-P, 786-O, Caki-2) was treated with phenoxodiol in vitro, and the efficacy of treatment was evaluated. RESULTS MTS assay results showed that phenoxodiol decreased renal cancer viability in a dose-dependent manner. In addition, it inhibited colony formation significantly and perturbed the cell cycle. Treatment with phenoxodiol increased the number of annexin-V-positive cells as well as the expression of cleaved poly ADP ribose polymerase, demonstrating that phenoxodiol induced apoptosis in renal cancer cells. Phenoxodiol also inhibited Akt pathway via dephosphorylation of Akt. CONCLUSION Phenoxodiol inhibited Akt pathway and induced apoptosis of renal cancer cells. The present study provides a theoretical basis for future development of a novel therapy effective against renal cancer.
