Abstract
Curcumin (CUR), a polyphenol, is an attractive component of functional foods, owing to various physiological activities. However, CUR is highly hydrophobic, insoluble in water, and difficult to absorb in the body. Here, we report an amorphous CUR formulation containing the dispersant polyglycerol fatty acid ester (PGFE), demonstrating high and stable water solubility. Improved water solubility enhanced the absorbability of CUR in our amorphous formulation along with enhanced triglyceride inhibition, compared to that in a commercial formulation. Nuclear Overhauser effect spectroscopy (NOESY) analysis revealed that PGFE reduced CUR-CUR interaction, resulting in higher dispersion and improved solubility of CUR. Taylor dispersion analysis showed a lower diffusion coefficient of CUR in the highly water-soluble formulation (with PGFE) than that in the low water-soluble formulation (without PGFE), which prevents recontact and recrystallization of CUR, which is trapped by PGFE. Overall, the amorphous CUR with high solubility could be used as a promising functional food.

Abstract
Gardenia blue powder was administered at 0.5%, 2.5%, or 5.0% in feed to male and female Sprague Dawley rats in an Extended One-Generation Reproductive Toxicity Study (OECD Test Guideline 443). The dosed diet began 14 days before mating and was continued at the same concentration level for the entire study for all parental animals (P0) and offspring (F1). At weaning, offspring were allocated into one of 5 cohorts for different endpoints. P0 and F1 animals had blue urine, blue or black feces, and blue discolorations in gastrointestinal organs, mesenteric lymph nodes, and kidneys. This treatment-related finding was not considered adverse as there were no histopathologic correlates. There was a dose-related increase in sperm concentration in P0 and F1 males. There were dose-related increases in heart weights of F1 postnatal day (PND) 21 males, male and female thyroid weights, and female TSH levels of PND 91 F1 offspring, with no histopathological correlate. There were no consistent treatment-related adverse effects on any other parameters evaluated for general toxicity, reproductive toxicity, developmental neurotoxicity, or developmental immunotoxicity. The highest dietary concentration (5.0%) of gardenia blue powder was the no observed adverse effect level (NOAEL) for male and female rats at all life stages evaluated.

Abstract
Toxicity assessment of the food colorant Gardenia jasminoides Ellis at dietary exposures of 0.0%, 0.1%, 0.5%, 1.5%, 3.0% and 5.0% included measures of T-cell- dependent antibody response, neurotoxicity, and clinical and anatomic pathology in Sprague Dawley rats during mating, gestation, lactation, postnatal development, and following weaning for up to 12 months including 3- and 6-month interim evaluations. Blue coloration of the gastrointestinal tract, mesenteric lymph nodes and kidneys was present in treated rats only at necropsy with minimal blue coloration at the lowest dose and without histopathological correlates in any of the tissues. There was good survival with no consistent treatment-related changes in hematology, clinical chemistry, enhanced evaluation of lymphoid tissues, or tissue histopathology at interim and final time points. T-cell dependent antibody response and neurotoxicity screening were negative in treated rats. The no-observed-adverse-effect level (NOAEL) was determined to be 5.0% gardenia blue (2,854.5 and 3,465.4 mg/kg/day in parental males and females, respectively, prior to mating; 3,113.5 and 4,049.6 mg/kg/day in male and female offspring, respectively, following up to 12 months of exposure.

Abstract
BACKGROUND Prior studies characterized the association of molecular alterations with treatment-specific outcomes in KRAS-mutant (KRASMUT) lung adenocarcinoma (LUAD). Less is known about the prognostic role of molecular alterations and their associations with metastatic disease. PATIENTS AND METHODS We analyzed clinicogenomic data from 1817 patients with KRASMUT LUAD sequenced at the Dana-Farber Cancer Institute (DFCI) and Memorial Sloan Kettering Cancer Center (MSKCC). Patients with metastatic (M1) and nonmetastatic (M0) disease were compared. Transcriptomic data from The Cancer Genome Atlas (TCGA) were investigated to characterize the biology of differential associations with clinical outcomes. Organ-specific metastasis was associated with overall survival (OS). RESULTS KEAP1 (DFCI: OR = 2.3, q = 0.04; MSKCC: OR = 2.2, q = 0.00027) and SMARCA4 mutations (DFCI: OR = 2.5, q = 0.06; MSKCC: OR = 2.6, q = 0.0021) were enriched in M1 versus M0 tumors. On integrative modeling, NRF2 activation was the genomic feature most associated with OS. KEAP1 mutations were enriched in M1 versus M0 tumors independent of STK11 status (KEAP1MUT/STK11WT: DFCI OR = 3.0, P = 0.0064; MSKCC OR = 2.0, P = 0.041; KEAP1MUT/STK11MUT: DFCI OR = 2.3, P = 0.0063; MSKCC OR = 2.5, P = 3.6 × 10-05); STK11 mutations without KEAP1 loss were not associated with stage (KEAP1WT/STK11MUT: DFCI OR = 0.97, P = 1.0; MSKCC OR = 1.2, P = 0.33) or outcome. KEAP1/KRAS-mutated tumors with and without STK11 mutations exhibited high functional STK11 loss. The negative effects of KEAP1 were compounded in the presence of bone (HR = 2.3, P = 4.4 × 10-14) and negated in the presence of lymph node metastasis (HR = 1.0, P = 0.91). CONCLUSIONS Mutations in KEAP1 and SMARCA4, but not STK11, were associated with metastatic disease and poor OS. Functional STK11 loss, however, may contribute to poor outcomes in KEAP1MUT tumors. Integrating molecular data with clinical and metastatic-site annotations can more accurately risk stratify patients.

Abstract
In this combined chronic toxicity/carcinogenicity study of gardenia blue as a natural food color additive, Sprague Dawley rats were administered 0.5%, 2.5%, or 5.0% gardenia blue via the feed or carrier diet (0.0% gardenia blue) for 12 (chronic toxicity cohort) or 24 (carcinogenicity cohort) months. No abnormal clinical, ophthalmological, neurotoxicity or clinical pathology changes were attributed to treatment, and there was no increase in mortality due to gardenia blue exposure. The only treatment-related change was grossly observed blue discoloration of the stomach, intestines, and mesenteric lymph nodes as well as reversible dark discoloration of the kidneys all without associated histopathology. The no-observed-adverse-effect level (NOAEL) for gardenia blue exposure via the diet for one or two years was determined to be 5.0% (2175.3 mg/kg body weight/day in male rats and 3075.4 mg/kg body weight/day in female rats).

Abstract
BACKGROUND Allele-specific KRAS inhibitors are an emerging class of cancer therapies. KRAS-mutant (KRASMUT) non-small-cell lung cancers (NSCLCs) exhibit heterogeneous outcomes, driven by differences in underlying biology shaped by co-mutations. In contrast to KRASG12C NSCLC, KRASG12D NSCLC is associated with low/never-smoking status and is largely uncharacterized. PATIENTS AND METHODS Clinicopathologic and genomic information were collected from patients with NSCLCs harboring a KRAS mutation at the Dana-Farber Cancer Institute (DFCI), Memorial Sloan Kettering Cancer Center, MD Anderson Cancer Center, and Imperial College of London. Multiplexed immunofluorescence for CK7, programmed cell death protein 1 (PD-1), programmed death-ligand 1 (PD-L1), Foxp3, and CD8 was carried out on a subset of samples with available tissue at the DFCI. Clinical outcomes to PD-(L)1 inhibition ± chemotherapy were analyzed according to KRAS mutation subtype. RESULTS Of 2327 patients with KRAS-mutated (KRASMUT) NSCLC, 15% (n = 354) harbored KRASG12D. Compared to KRASnon-G12D NSCLC, KRASG12D NSCLC had a lower pack-year (py) smoking history (median 22.5 py versus 30.0 py, P < 0.0001) and was enriched in never smokers (22% versus 5%, P < 0.0001). KRASG12D had lower PD-L1 tumor proportion score (TPS) (median 1% versus 5%, P < 0.01) and lower tumor mutation burden (TMB) compared to KRASnon-G12D (median 8.4 versus 9.9 mt/Mb, P < 0.0001). Of the samples which underwent multiplexed immunofluorescence, KRASG12D had lower intratumoral and total CD8+PD1+ T cells (P < 0.05). Among 850 patients with advanced KRASMUT NSCLC who received PD-(L)1-based therapies, KRASG12D was associated with a worse objective response rate (ORR) (15.8% versus 28.4%, P = 0.03), progression-free survival (PFS) [hazard ratio (HR) 1.51, 95% confidence interval (CI) 1.45-2.00, P = 0.003], and overall survival (OS; HR 1.45, 1.05-1.99, P = 0.02) to PD-(L)1 inhibition alone but not to chemo-immunotherapy combinations [ORR 30.6% versus 35.7%, P = 0.51; PFS HR 1.28 (95%CI 0.92-1.77), P = 0.13; OS HR 1.36 (95%CI 0.95-1.96), P = 0.09] compared to KRASnon-G12D. CONCLUSIONS KRASG12D lung cancers harbor distinct clinical, genomic, and immunologic features compared to other KRAS-mutated lung cancers and worse outcomes to PD-(L)1 blockade. Drug development for KRASG12D lung cancers will have to take these differences into account.

Abstract
An 89-year-old woman presented to our clinic with a complaint of a wound in the left nipple. The pathological diagnosis via skin biopsy revealed adenocarcinoma. A physical examination, mammography, ultrasonography, and CT scan revealed a mass in the left nipple. However, a definite diagnosis could not be established by skin biopsy. Left breast-conserving surgery and sentinel lymph node biopsy were performed for diagnosis and treatment. Histological examination revealed a scirrhous type invasive ductal carcinoma in the left nipple and areola with skin invasion and lymph node metastasis. Radiation and hormone therapy were used as adjuvant therapy. She is alive with no local recurrence for 5 months post surgery. Since ductal carcinoma of the nipple is uncommon, we present this case report along with a review of the relevant literature.

Abstract
Background/Introduction
Although second-generation drug eluting stent (DES) employing biodurable polymer drastically shortened the duration of dual antiplatelet therapy (DAPT), previous reports raised concerns that switching from DAPT to single antiplatelet therapy increased rates of subsequent stent thrombosis with time. Third-generation DES employing bioabsorbable polymer has been introduced so as not to hinder the healing process of the vessel wall, however, at present, both DES with bioabsorbable polymer and those with biodurable polymer are used in parallel. It means there is no conclusive evidence regarding pros and cons of these two types of polymers.
Purpose
This study aims to clarify how bioabsorbable polymer and biodurable polymer act on the human coronary artery by observing neointimal stent coverage (NIC) and in-stent thrombus by comparing the third-generation DES with bioabsorbable-polymer cobalt-platinum everolimus-eluting stent (BP CoPt-EES), and the second-generation DES with biodurable-polymer cobalt-chromium everolimus-eluting stent (DP CoCr-EES).
Methods
This is a multicenter observational study including 11 hospitals. We investigated 70 stents (BP CoPt-EES: 40, DP CoCr-EES: 30) of 60 cases, who underwent stent implantation followed by simultaneous observation by coronary angiography, IVUS and angioscopy within 6 to 12 months. For angioscopy, we used a recently available, high-resolution angioscope with a pixel count of 9,000 which realized both stent coverage analysis and planar thrombus detection precisely. Neointimal stent coverage was graded from G0: non coverage to G3: full coverage, and heterogeneity value of neointima was measured as the difference between maximum and minimum NIC grade.
Results
A strong relationship was observed between NIC grade and in-stent thrombus in all stents (p=0.0011), and between the heterogeneity value and stent thrombus (p=0.012). There was no statistical difference in NIC grade between BP CoPt-EES vs. DP CoCr-EES; grade 0: 0 (0.0%) vs. 2 (6.7%), grade 1: 13 (32.5%) vs. 11 (36.7%), grade 2: 6 (15.0%) vs. 6 (20.0%), grade 3: 21 (52.5%) vs. 11 (36.7%), p=0.17) and neither in the heterogeneity value of neointima (p=0.49). The ratio of stent thrombus did not reach statistical difference; 16 (40.0%) in BP CoPt-EES vs. 17 (56.7%) in DP CoCr-EES (p=0.23).
Conclusion
The existence of stent thrombus was associated with the neointimal stent coverage. There was no significant difference both in neointimal stent coverage and stent thrombus between bioabsorbable polymer cobalt-platinum EES and biodurable polymer cobalt-chromium EES after 6 to 12 months following stent deployment.

Abstract
Abstract
Background
BIOSCIENCE randomized trial which compared biodegradable-polymer sirolimus-eluting stents with ultra-thin (60μm) strut (ultra-thin BP-SES) and durable-polymer everolimus-eluting stents with thin (81μm) strut (thin DP-EES) have reported that definite stent thrombosis within 1 year had more frequently occurred in ultra-thin BP-SES (0.9%) than in thin DP-EES group (0.4%) although it was not statistically significant. It suggests that neointimal coverage after stent implantation within 1 year might be different between ultra-thin BP-SES and thin DP-EES. Recently, two types of biogradable-polymer sirorimus eluting stents, thin (80μm) strut type (thin BP-SES) and ultra-thin (60μm) strut type (ultra-thin BP-SES), can be available in clinical settings.
Purpose
We compared neointimal coverage conditions between ultra-thin BP-SES and thin BP-SES by optical coherence tomography (OCT).
Methods
Consecutive Forty-six patients who underwent 21 ultra-thin BP-SESs or 25 thin BP-SESs implantation were enrolled. We compared incidences of acute coronary syndrome, type B2/C lesion, atherectomy device use, stent size, stent length, maximum inflation pressure, and 8-month follow-up OCT parameters including proportions of uncovered struts (%Uncovered), malapposed struts, (%Mallaposed) and mean neointimal hyperplasia thickness (mean NHT) between the two groups.
Results
%Uncovered and %malapposed were significantly higher and mean NHT was significantly lower in ultra-thin BP-SES than in thin BP-SES (Table). The other parameters were similar between the two groups.
Conclusion
Ultra-thin BP-SES showed worse neointimal coverage as compared to thin BP-SES within 1 year after stent implantation, which may increase stent thrombosis.

Abstract
Abstract
Introduction
ILUMIEN III trial has reported that non-inferiority of optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) to intravascular ultrasound-guided PCI for postprocedural minimum stent area. In the trial, external elastic lamina (EEL)-based stent sizing criteria was introduced, however OCT has limitations including incomplete visualization of EEL in severale lesions.
Purpose
The aim of the study is to investigate real-world clinical impact of EEL-based stent sizing criteria.
Methods
The study included consecutive patients who underwent OCT-guided percutaneous coronary intervention (PCI) for de novo lesions in our institution between September 2016 and April 2018. EEL visibility, mean EEL diameter, mean lumen diameter and plaque morphology were assessed at proximal and distal references. The plaque morphology at references was categorized according to its most prevalent component as follows: normal, fibrous plaque, lipid plaque, and calcified plaque. Both references were divided into 3 groups according to visibility of EEL.
Results
Among 205 lesions, 31 lesions had artifacts at references (16 proximal and 17 distal references). EEL visibility was summarized in a table. Out of 174 lesions with both analyzable references, 111 lesions (63.8%) had >180-degree EEL visibility at both references. Proportion of plaque morphology were significantly different among 3 groups at proximal and distal references as shown in a figure.
Conclusions
EEL-based stent sizing criteria was usable for 63.8% of all the lesions. Vessel size and plaque morphology were significantly associated with EEL visibility.

Abstract
Abstract
Background
Pulmonary vein isolation (PVI) has become well-established as the main therapy for patients with drug-refractory paroxysmal atrial fibrillation (PAF) and various isolation methods including radiofrequency ablation (RFA), cryoballoon ablation (CBA) and laser balloon ablation (LBA) were available. Pathological findings in each ablation methods such as myocardial injury and inflammation are thought to be different. High sensitive cardiac troponin I (hs-TnI), subunit of cardiac troponin complex, is a sensitive and specific marker of myocardium injury. High-sensitive C-reactive protein (hs-CRP) is a biomarker of inflammation and is elevated following cardiomyocyte necrosis. Relationship between myocardial injury and inflammation after ablation using RFA, CBA and LBA and early recurrence of atrial fibrillation (ERAF) remains unclear.
Methods
We enrolled consecutive PAF patients from Osaka Rosai Atrial Fibrillation (ORAF) registry who underwent PVI from January 2019 to October 2019. We compared the clinical characteristics including age, gender, hypertension, diabetes mellitus, history of heart failure, CHADS2Vasc score, renal function, serum BNP level and echocardiographic parameters including left ventricular dimensions, left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) between RFA, CBA and LBA groups. We investigated the difference of relationship between myocardial injury marker (hs-TnI), inflammation markers (white blood cell change (DWBC) from post to pre PVI, neutrophil-to-lymphocyte ratio change (DNLR) from after to before PVI and hs-CRP) at 36–48 hours after PVI and ERAF (<3 months after PVI) between each group.
Results
We enrolled 187 consecutive PAF patients who underwent PVI. RFA, CBA and LBA groups comprised 108, 57 and 22 patients, respectively. There were no significant differences of age, gender, hypertension, diabetes mellitus, history of heart failure, CHADS2Vasc score, renal function, serum BNP level and echocardiographic parameters between each group. Serum hs-TnI in RFA group and LBA group were significantly lower than in CBA group (2.643 ng/ml vs 5.240ng/ml, 1.344 ng/ml vs 5.240 ng/ml, p<0.001, p=0.002, respectively, Figure). DWBC was significantly higher in LBA group than CBA group (1157.3/μl vs 418.4/μl, p=0.045). DNLR did not differ between each group. Hs-CRP in RFA group and LBA group were significantly higher than in CBA group (1.881 mg/dl vs 1.186 mg/dl, 2.173 mg/dl vs 1.186 mg/dl, p=0.010, p=0.003, respectively, Figure). Incidence of ERAF was significantly higher in LBA group than RFA group (36.4% vs 16.7%, p=0.035). Incidence of ERAF tended to be higher in LBA group than CBA group (36.4% vs 19.3%, p=0.112).
Conclusion
LBA may cause less myocardial injury than RFA and CBA, on the contrary LBA may cause more inflammation than CBA. Incidence of ERAF in LBA was highest between each procedure.

Abstract
Background
Little has been reported on the outcome of contact force (CF)-guided radiofrequency catheter ablation (RFCA) and second generation cryoballoon ablation (CBA).
Purpose
The purpose of this study was to compare the outcome of CF-guided RFCA and second generation CBA for paroxysmal atrial fibrillation (PAF).
Methods
We enrolled the consecutive 364 patients with PAF who underwent initial ablation between September 2014 and July 2018 in our hospital. We compared the late recurrence of atrial tachyarrhythmia more than three months after ablation between RFCA group and CBA group. All RFCA procedures were performed using CF-sensing catheter and all CBA procedures were performed using second generation CB.
Results
There were significant differences in background characteristics: chronic kidney disease, serum brain natriuretic peptide level, and left ventricular ejection fraction. After propensity score matched analysis (Table), atrial tachyarrhythmia free survival was significantly higher in CBA group than in RFCA group (Figure).
Conclusions
Second generation CBA showed a significantly lower late recurrence rate compared to CF-guided RFCA.

Abstract
Abstract
Background
Power and total energy were known to correlate with lesion formation during laser balloon ablation for atrial fibrillation. However, it is unclear whether balloon size can influence lesion formation. The aim of this study was to evaluate the impact of balloon size on lesion formation during laser balloon procedure in vitro model.
Methods
Laser energy was applied to chicken muscles using first generation laser balloon. Laser ablation was performed with different 2 balloon size (18mm and 32mm) using 2 different power settings (12W/20sec and 8.5W/20sec). Forty lesions were evaluated for each setting. We compared maximum lesion width, maximum lesion depth, depth at maximum width and endocardial lesion width between 18mm and 32mm balloon groups at 12W/20sec and 8.5W/20sec, respectively.
Results
At 8.5W/20sec, inadequate lesion formation to assess lesion size was observed in 1/40 lesion of 18mm balloon group and in 5/40 lesions of 32mm balloon group. Thus, at 8.5W/20sec 18 mm balloon group consisted of 39 lesions and 32 mm balloon group consisted of 35 lesions. At 12W/20sec 18 mm balloon group consisted of 40 lesions and 32 mm balloon group consisted of 40 lesions. At both power settings, maximum lesion depth was larger in 18mm balloon than in 32mm balloon group. At 12W/20sec setting, maximum lesion width and endocardial width were larger in 32mm balloon group than in 18mm balloon group. At 12W/20sec setting, depth at maximum width was smaller in 32mm balloon group than in 18mm balloon group. Lesion morphologies were summarized in a figure.
Conclusion
Balloon size could affect lesion formation during laser balloon ablation in addition to laser power and energy. Laser ablation lesion were wider but shallower in 32mm balloon group compared with in 18mm balloon group.

Abstract
Abstract
Background
Complete right bundle branch block (CRBBB) is one of the most frequent alterations of the electrocardiogram (ECG). Several studies have shown that CRBBB was a risk factor for cardiovascular diseases and the appearance of CRBBB in patients hospitalized for exacerbated heart failure (HF) was associated with a worse prognosis. Various alternations of ECG such as early repolarization pattern and intraventricular conduction disturbance were associated with high recurrence ratio of atrial fibrillation (AF) after pulmonary vein isolation (PVI). However clinical outcome after PVI in patients with CRBBB remains unclear.
Methods
We enrolled consecutive AF patients who underwent PVI from September 2014 to November 2018 rom Osaka Rosai Atrial Fibrillation (ORAF) registry. We excluded patients with other wide QRS (left bundle branch block, ventricular pacing and unclassified intraventricular conduction disturbance) and divided into 2 groups; CRBBB (QRS duration ≥120msec) group and no-CRBBB (QRS duration <120) group. We compared the clinical characteristics including age, gender, hypertension, diabetes mellitus, history of heart failure, history of stroke, CHADS2Vasc score, paroxysmal AF (PAF), renal function, plasma brain natriuretic peptide (BNP) level and echocardiographic parameters including left ventricular end-diastolic diameter (LVDd), left ventricular end-systolic diameter (LVDs), left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) between the 2 groups. We also compared the incidence of late recurrence of AF/atrial tachycardia (AT) between the 2 groups. We investigated whether CRBBB was an independent predictor of late recurrence of AF/AT after PVI by multivariate Cox analysis.
Results
We enrolled 736 consecutive AF patients who underwent PVI. CRBBB patients comprised 55 patients (7.5%). There were no significant differences of age, gender, hypertension, diabetes mellitus, history of heart failure, history of stroke, CHADS2Vasc score, PAF, renal function, plasma BNP level and echocardiographic parameters (LVDd, LVDs, LVEF and LAD) between the 2 groups. Incidence of AF/AT recurrence after PVI was significantly higher in CRBBB group than no-CRBBB group (Figure). CRBBB was an independently and significantly associated with late recurrence of AF/AT after PVI by multivariate Cox analysis (hazard ratio: 1.923, 95% CI: 1.190–2.961, p=0.009) in addition to female (p<0.001), no-PAF (p=0.005) and left atrial diameter (p=0.042).
Conclusion
CRBBB may be a strong predictor of AF/AT late recurrence after PVI.

Abstract
Abstract
Background
It has been reported that frequent use of touch-up focal ablation catheters was related to worse outcomes after cryoballoon (CB) atrial fibrillation (AF) ablation. It is unknown whether non-use of touch-up focal ablation catheters strategy affects the outcome of AF ablation. Therefore, this study aimed to assess whether non-use of touch-up focal ablation catheters strategy improve clinical outcome after AF ablation using CB.
Methods
A total of 151 consecutive patients who received CB ablation from February 2017 to August 2019 were enrolled. Non-use of a touch-up focal ablation catheters strategy was started from February 2018. Patients were divided into 2 groups according to the type of strategy. In the non-touch-up group, pulmonary veins were isolated without touch-up focal ablation catheters as much as possible and in conventional group, touch-up focal ablation catheters were used as required. The 1-year atrial tachyarrhythmia free survival without class 1 or 3 antiarrhythmic drugs after a 90-day blanking period was assessed between the 2 groups.
Results
The conventional group consisted of 76 patients and the non-touch-up group consisted of 75 patients. Baseline characteristics were comparable between 2 groups. Touch-up focal ablation catheters were used more in the conventional group (11 patients, 14%) than non-touch-up group (0 patients, 0%) (p<0.001). Pulmonary isolation was achieved in all patients of both groups. Atrial tachyarrhythmia recurrence occurred more frequently in the non-touch-up group (15/75 patients, 20%) than conventional group (7/76 patients, 9%) (p=0.045).
Conclusion
Non-use of a touch-up focal ablation catheters strategy may be related to worse outcome after CB AF ablation.

Abstract
Abstract
Background
Ablation index (AI) is a novel marker of ablation lesion quality for radiofrequency ablation (RFA). It has been reported that AI guided pulmonary vein isolation (PVI) reduced pulmonary vein reconnection and late recurrence of atrial fibrillation (AF). However, little is known about the impact of AI guided PVI on early recurrence of AF (ERAF).
Purpose
The aim of this study is to clarify whether AI guided PVI can reduce ERAF.
Methods
From September 2014 to August 2019, consecutive AF patients who underwent 1st session PVI were enrolled. We compared prevalence of ERAF between AI guided PVI group (AI group) and conventional contact force guided PVI group (CF group) using propensity score-matched analysis, which adjusted patient backgrounds (age, sex, and body mass index (BMI)), type of AF, the history of heart failure, hypertension, diabetes and stroke, laboratory findings including estimated glomerular filtration rate (eGFR) and b-type natriuretic peptide (BNP), and echocardiographic parameters including left ventricular ejection fraction (LVEF) and left atrial diameter.
Results
Total 711 patients were enrolled. AI group comprised 233 patients and CF group comprised 233 patients. Prevalence of ERAF were significantly lower in AI group than in CF group significantly (21.5% vs 36.1%, p=0.001, Table).
Conclusions
AI guided PVI can reduce ERAF as compared to conventional method.

Abstract
Abstract
Background
It has been reported that elimination of non-pulmonary vein (PV) triggers after PV isolation is a good predictor of atrial tachyarrhythmia free survival. However, precise mapping of triggers outside from superior vena cava (SVC) or left atrial posterior wall (LAPW) are difficult. The aim of this study is to assess the efficacy of self-reference mapping technique to eliminate non-PV triggers originated from outside of primordial pulmonary vein area.
Methods
Total of 431 patients (446 procedures) underwent atrial fibrillation (AF) ablation in a hospital and in a medical center from January 2017 to March 2019. After isolation of PV, non-PV triggers were induced with isoproterenol and/or adenosine triphosphate. Reproducible non-PV triggers were targeted to ablate using following self-reference mapping technique: A trigger conducts centrifugally and the earliest site should be distinguished from other later activated sites. Using a PentaRay multipolar catheter, the operators annotated the earliest site of local activation and a reference tag was placed. The multipolar catheter was then moved to the reference tag and the process repeated. Ultimately, we identified clusters of early circumferential activation and ablated.
Results
A total of 32 non-PV triggers excluding the origin from LAPW and SVC were induced in 23 patients. Nineteen triggers (59%) were located in the right atrium and 13 triggers (41%) in the left atrium (Figure 1). All triggers were eliminated with ablation and AF was non-inducible in all patients at the end of the procedure. During the follow-up (529±270 days), 18 patients (77%) were free from atrial tachyarrhythmias after a 3-month blanking period. Three patients received additional ablation procedures for recurrent atrial arrhythmias. No non-PV triggers ablated during the previous procedure were observed.
Conclusion
A novel self-reference mapping technique is useful for eliminating non-PV triggers in terms of the short- and long-term success.

Abstract
Abstract
Background Five-year adjuvant treatment with aromatase inhibitors is a standard treatment for postmenopausal women with estrogen receptor-positive breast cancer. However, aromatase inhibitor-related adverse events, including joint and vasomotor symptoms, have a strong impact on patient quality of life and sometimes cause the discontinuation of treatment. The aim of this prospective cohort study based on patient-reported outcomes (PROs) was to examine the influence of adverse events on prognosis in Japanese postmenopausal patients with breast cancer treated with adjuvant anastrozole. Patients and Methods A total of 391 postmenopausal Japanese women with estrogen receptor-positive breast cancer who were treated with adjuvant anastrozole were enrolled from 28 centers in this prospective cohort study (SAVS-JP, UMIN000002455). PRO assessments of adverse events, which included joint and vasomotor symptoms, were obtained at baseline and 3, 6, 9, and 12 months. Symptoms were assessed and assigned to one of four categories: none (G0), mild (G1), moderate (G2), and severe (G3). The questionnaires covered joint symptoms (arthralgia, decrease in range of joint motion, and joint stiffness), vasomotor symptoms (hot flashes, night sweats, and cold sweats), and adherence to anastrozole. The median follow-up was 82 months, and we analyzed the prognosis in patients, focusing on the occurrence of joint and vasomotor symptoms induced by treatment. Results Of the 391 patients, 204 (52.2%) completed 5-year treatment, 75 (19.2%) discontinued (adverse events (n=35), recurrence (n=19), secondary malignancies (n=4), death from non-breast cancer (n=4), and other reasons (n=13)), 48 (12.3%) are receiving treatment, and 64 (16.4%) were unknown. Patients who experienced G2+3 joint symptoms had significantly better disease-free survival (DFS) compared with patients with G0+1 joint symptoms (5-year DFS, 96.1% vs. 83.3%, p=0.002). Similarly, the DFS in patients with G2+3 vasomotor symptoms was significantly better than that in those with G0+1 vasomotor symptoms (5-year DFS, 93.5% vs. 86.3%, p=0.049). Joint symptoms were marginally associated with overall survival (OS) (p=0.062), but no significant association was found with vasomotor symptoms. The DFS was superior in patients with G2+3 joint and vasomotor symptoms (5-year DFS, 100%), inferior in those with G0+1 joint and vasomotor symptoms (5-year DFS, 82.6%), and intermediate in others (5-year DFS, 93.3%; p=0.0024). By multivariable analysis including tumor size and grade, G2+3 joint symptoms were a significant and independent predictive factor for DFS (hazard ratio, 0.298, 95% confidence interval 0.122-0.621, p=0.0007). Conclusion Although adverse events might make patients uncomfortable and reduce their quality of life, it is suggested that worse or new vasomotor symptoms and severe joint symptoms, especially if they are grade 2 or 3, seem to associate with better prognosis.

Abstract
Background: Immune checkpoint inhibitors (ICIs) are standard therapies for patients with advanced non-small-cell lung cancer (NSCLC) and a programmed death-ligand 1 (PD-L1) tumor proportion score (TPS) ≥50%. Tumor mutation burden (TMB) also predicts response to ICIs but is often not available in real time for decision making in the first-line setting. Smoking exposure can be a proxy for TMB in NSCLC. The impact of smoking status on efficacy of PD-1 blockade in NSCLC patients with PD-L1 TPS ≥50% has not been well defined. Patients and methods: To investigate the relationship between smoking and activity of ICIs in NSCLC, we retrospectively studied 315 patients with NSCLC and PD-L1 TPS ≥50% at five USA academic medical centers. Objective response rates (ORRs), progression-free survival (PFS), and duration of response (DOR) were compared between never (<100 lifetime cigarettes), light (≤10 pack-years), and heavy (>10 pack-years) smokers. A subset of patients underwent next-generation sequencing to estimate TMB. Results: We identified 36 (11%) never, 42 (13%) light, and 237 (75%) heavy smokers with NSCLC and PD-L1 TPS ≥50% treated with ICIs. Objective responses were observed in 27%, 40%, and 40% of never, light, and heavy smokers, respectively (P = 0.180 never versus heavy; P = 1.000 light versus heavy). Median PFS and median DOR were numerically shorter in never and light smokers compared with heavy smokers (PFS 3.0 versus 4.0 versus 5.4 months; median DOR 6.9 versus 10.8 versus 17.8 months), but were not statistically different [PFS: hazard ratio (HR) 1.37, P = 0.135 and HR 1.24, P = 0.272; DOR: HR 1.92, P = 0.217 and HR 1.79, P = 0.141]. Conclusions: PD-(L)1 inhibitors are associated with antitumor activity in NSCLC with PD-L1 TPS ≥50% regardless of smoking status. Nevertheless, there is a signal of potentially decreased durability among never and light smokers that should be further evaluated. Distinct immunobiologic features may affect initial response versus durability of antitumor immunity to programmed cell death 1 (PD-1) blockade.

Abstract
Background MET exon 14 alterations are actionable oncogenic drivers. Durable responses to MET inhibitors are observed in patients with advanced MET exon 14-altered lung cancers in prospective trials. In contrast, the activity of immunotherapy, PD-L1 expression and tumor mutational burden (TMB) of these tumors and are not well characterized. Patients and methods Patients with MET exon 14-altered lung cancers of any stage treated at two academic institutions were identified. A review of clinicopathologic and molecular features, and an analysis of response to single-agent or combination immune checkpoint inhibition were conducted. PD-L1 immunohistochemistry was carried out and TMB was calculated by estimation from targeted next-generation sequencing panels. Results We identified 147 patients with MET exon 14-altered lung cancers. PD-L1 expression of 0%, 1%-49%, and ≥50% were 37%, 22%, and 41%, respectively, in 111 evaluable tumor samples. The median TMB of MET exon 14-altered lung cancers was lower than that of unselected non-small-cell lung cancers (NSCLCs) in both independently evaluated cohorts: 3.8 versus 5.7 mutations/megabase (P < 0.001, n = 78 versus 1769, cohort A), and 7.3 versus 11.8 mutations/megabase (P < 0.001, n = 62 versus 1100, cohort B). There was no association between PD-L1 expression and TMB (Spearman's rho=0.18, P = 0.069). In response-evaluable patients (n = 24), the objective response rate was 17% (95% CI 6% to 36%) and the median progression-free survival was 1.9 months (95% CI 1.7-2.7). Responses were not enriched in tumors with PD-L1 expression ≥50% nor high TMB. Conclusion A substantial proportion of MET exon 14-altered lung cancers express PD-L1, but the median TMB is lower compared with unselected NSCLCs. Occasional responses to PD-1 blockade can be achieved, but overall clinical efficacy is modest.

Abstract
Abstract
Background
Recent reports revealed that residual area stenosis (% AS) ≤30% after lesion preparation is a suitable predictor for target lesion revascularization (TLR) after drug-coated balloon (DCB) treatment for in-stent restenosis (ISR). Excimer laser coronary angioplasty (ELCA) can obtain larger lumen area and may be more useful for lesion preparation than plain old ballooning (POBA). On the other hands, it has been reported that in-stent neoatherosclerosis (NA) is major cause of restenosis. It is unclear the correlation between NA of ISR and the effect of ELCA. Thus, we compared the influence of NA which was evaluated by optical coherence tomography (OCT) on % AS for ISR treatment between ELCA and DCB (ELCA) group and POBA and DCB (non-ELCA) group and their clinical outcome.
Methods
We enrolled 58 consecutive ISR lesions which were treated by OCT guidance between July 2014 and July 2018 in our hospital. The lesions were divided into NA and non-NA lesions according to OCT findings. In each lesion, we compared post procedural % AS and % AS change which was calculated by the difference between pre and post procedural % AS between ELCA and non-ELCA groups. In addition, we compared 8-month major advance cardiac events (MACE) defined by composite of binary restenosis and target lesion revascularization (TLR) between ELCA and non-ELCA group in NA lesions.
Results
There were 19 NA (33.3%) and 39 non-NA lesions. In NA lesions, ELCA group can obtain significantly lower % AS (p=0.02) and significantly larger % AS change (p<0.01) than non-ELCA group, but in non-NA lesions, % AS and %AS change were similar between ELCA and non-ELCA groups (table). In 8-month clinical outcome, non-ELCA group experienced MACE twice as much as ELCA group did. (31% vs 17%)
Results of %AS NA lesions (n=19) P value non-NA lesions (n=39) P value ELCA group (n=6) non-ELCA group (n=13) ELCA group (n=17) non-ELCA group (n=22) Post %AS (%) 2±21 26±25 0.02 7±29 23±19 0.07 %AS change (%) 71±15 38±19 <0.01 56±29 44±17 0.11
Conclusion
Although neoatherosclerosis is correlated with refractory restenosis, ELCA can improve residual area stenosis in neoatherosclerosis lesions and can achieve better clinical outcomes for in-stent neoatherosclerosis.

Abstract
Background
New generation drug eluting stents (DES) have improved target vessel failure as compared with early generation DES and bare metal stent. Contemporary several new generation DES are different each other regarding strut thickness and drug and polymer type. A little is known about which stent induces a more favorable vascular healing at follow up.
Purpose
In this study, we compared the vascular healing at 8-month follow up by optical coherence tomography (OCT) between 4 different kinds of new generation DES.
Methods
We enrolled 112 consecutive patients (121 lesions) who underwent PCI using 4 kinds of new generation DES including biodegradable-polymer everolimus-eluting stents (BP-EES), biodegradable-polymer sirolimus-eluting stents (BP-SES), durable-polymer everolimus-eluting stents (DP-EES) and durable-polymer zotarolimus-eluting stents (DP-ZES) and who underwent 8-month follow up angiogram and OCT between July 2016 and April 2018. We compared the OCT parameters including percentage of covered struts, uncovered struts, well-apposed and uncovered struts, malapposed strut and mean neointimal hyperplasia (NIH) thickness between them.
Results
BP-EES consisted of 29 lesions, BP-SES consisted of 25 lesions, DP-EES consisted of 38 lesions and DP-ZES consisted of 29 lesions. A total of 734 frames with 5163 struts in BP-EES, 481 frames with 4214 struts in BP-SES, 783 frames with 6119 struts in DP-EES and 583 frames with 4708 struts in DP-ZES were analyzed. As shown in a table, mean NIH thickness was significantly higher in BP-EES and BP-SES. Thus, we compared the OCT parameters between durable-polymer (DP) group including DP-ZES and DP-EES and biodegradable-polymer (BP) group including BP-EES and BP-SES. The percentage of uncovered struts was significantly lower and mean NIH thickness was significantly higher in BP group than DP group.
Results of OCT parameters BP-EES (n=29) BP-SES (n=25) DP-EES (n=38) DP-ZES (n=29) P value BP group (n=54) DP group (n=67) P value Covered struts (%) 89.5±13.6 92.4±8.6 85.5±17.5 85.0±17.7 0.29 90.9±11.6 85.3±17.4 0.08 Uncovered struts (%) 8.8±10.8 7.1±8.7 14.5±17.5 15.0±17.7 0.14 8.0±9.9 14.7±17.4 0.03 Well-apposed and uncovered struts (%) 7.9±9.9 5.9±7.7 11.7±13.1 12.3±14.0 0.15 7.0±8.9 11.9±13.4 0.04 Malapposed struts (%) 0.8±1.6 1.3±2.2 2.7±5.8 2.7±4.7 0.33 1.0±1.9 2.7±5.3 0.07 Mean NIH thickness (μm) 102±57 121±48 78±28 88±33 <0.01 111±53 82±31 <0.01
Conclusion
The present OCT study demonstrated that delayed neointimal healing characterized by the presence of uncovered struts and lower mean NIH thickness was less common in BP group than DP gruop. Biodegradable-polymer may be more favorable than durable-polymer from the point of view of vascular healing.

Abstract
Abstract
Background
Several reports have revealed that stent under expansion is associated with target lesion failure and calcified lesions usually induced inadequate stent expansion. Contemporary debulking devices such as rotational/orbital atherectomy can modify severe calcified lesions before stenting. However, it is uclear which calcium parameter is most useful predictor for stent expansion in the calcified lesions. Thus, we investigated useful calcium parameters correlating with stent expansion in the calcified lesions.
Methods
We enrolled 43 consecutive calcified lesions (43 patients) who underwent optical coherence tomography (OCT) guided percutaneous coronary intervention (PCI) between September 2016 and January 2019. We evaluated the lesions treated with post dilatation by non-compliant balloon due to stent under expansion after stenting. Exclusion criteria included acute coronary syndrome, in-stent restenosis and lesions without any calcium or treated with rotational atherectomy. If there were several calcium lesions in one patient, we selected maximum calcium angle lesion. Stent expansion defined as post-PCI lumen area divided by the values predicted by the manufactures compliance charts. We compared mean reference area, pre lesion area stenosis, calcium parameters including calcium arc, maximum thickness, area and longitudinal length in pre-PCI OCT evaluations with post-PCI stent expansion at that site.
Results
Maximum calcium thickness showed significant correlation with stent expansion, while the others did not show a significant correlation with stent expansion (table). The optimal thresholds of maximum calcium thickness for the prediction of acceptable stent expansion defined by 80% of the values predicted by the manufactures compliance charts was 870mm (area under curve (AUC): 0.65) (figure).
Results of OCT parameters Univariate analysis P value Mean reference area 0.41 Pre % area stenosis 0.16 Calcium parameters Calcium arc 0.37 Calcium maximum thickness 0.04 Calcium area 0.20 Calcium longitudinal length 0.43
Conclusion
A maximum calcium thickness<870mm is a useful predictor for acceptable stent expansion after post dilatation in calcified lesions.

Abstract
Abstract
Background
Over the last decade, drug-eluting stents (DES) have undergone substantial modifications with thinner struts and more biocompatible durable polymer (DP) or biodegradable polymer (BP). In DP-based DES, after drug elusion has been completed, DP remnants may trigger of local inflammatory vascular reactions and promote delayed healing, leading to accelerated neoatherosclerosis (NA). Thus, BPs have been developed to reduce the above-mentioned risks. Recently, poor strut coverage and in-stent NA are increasingly recognized the cause of late stent failure, but it is unclear whether BPs can reduce the incidence of NA and the poor stent coverage as compared to DPs.
Objectives
The purpose of this study was to compare the incidence of NA and the stent coverage using optical coherence tomography (OCT) between the DPs and the BPs.
Methods
Between July 2016 and April 2018, 127 consecutive patients with new-generation DES who underwent 8-month follow up OCT imaging were enrolled. Patients were divided into the two groups: DP group who had the new-generation durable polymer everolimus-eluting and zotarolimus-eluting stents and BP group who had the new-generation biodegradable polymer sirolimus-eluting and everolimus-eluting stents. We compared patient characteristics including hypertension, dyslipidemia and diabetes mellitus and 8-month follow up OCT findings including NA, uncovered struts and malapposed struts between the two groups.
Results
The DP group comprised 64 patients (50.4%. The incidence of NA, uncovered struts and malapposed struts were similar between the two groups (DPs vs BPs, 1.56% vs 7.94%, P=0.11; 7.80% vs 5.88%, P=0.16 and 2.76% vs 2.01%, P=0.43, respectively) (table). The other parameters were also similar between the two groups.
Table 1 DP group (n=64) BP group (n=63) P value Hypertension 44 (68.8%) 50 (79.4%) 0.2251 Dyslipidemia 39 (60.9%) 37 (58.7%) 0.8573 Diabetes mellitus 25 (39.1%) 30 (47.6%) 0.3731 8 month OCT follow up findings Neoatherosclerosis 1 (1.6%) 5 (7.9%) 0.1147 Uncovered struts 7.8% (2.8–20.4) 5.9% (0.7–16.7) 0.1616 Malapposed struts 0.2% (0–2.8) 0% (0–2.8) 0.4392
Conclusions
The new-generation DP based-DES may have similar effects on vascular response compared to the new-generation BP-based DES during 8-month follow-up period.

Abstract
Abstract
Background
Several studies using optical coherence tomography (OCT) have shown that the prevalence of irregular protrusion was associated with the incidence of adverse cardiac events. However, the correlation between cardiac events and protrusion area is not well investigated.
Method
One hundred twenty-nine consecutive patients with 138 clesions with 2nd and 3rd generation drug-eluting stents (DES) which had pre-stenting and post-stenting OCT imaging between April 2016 and April 2018 were evaluated. We compared baseline characteristics, procedure findings and OCT findings including minimum stent area, protrusion type and maximum protrusion area between target lesion revascularization (TLR) group and non-TLR group.
Results
TLR occurred in 12 (9.3%) in 129 patients. The baseline characteristics and procedure findings were similar between TLR group and non-TLR group. Univariate analysis revealed that maximum irregular protrusion area was significantly larger (0.51 [0.00–0.63] vs 0.00 [0.00–0.27], p=0.036) in TLR group than non-TLR group. Receiver operating characteristic curve analysis revealed that the suitable cutoff value of maximum irregular protrusion area were 0.43mm2 for TLR. In multivariate analysis using the parameters with p value<0.10 determined by univariate analysis, maximum irregular protrusion (≥0.43mm2) and minimum stent area (MSA) were independently correlated with TLR (table).
Odd's ratio (95% CI) P value Major irregular protrusion (≥0.43mm2) 17.3 (3.63–82.6) <0.001 MSA 2.13 (1.15–3.93) 0.002
Conclusion
Major irregular protrusion (>0.43mm2) in post-stenting OCT findings may be a powerful predictor of TLR in the patients with new generation DES.

Abstract
BACKGROUND In non-small-cell lung cancers with programmed death-ligand 1 (PD-L1) expression on ≥50% of tumor cells, first-line treatment with the PD-1 inhibitor pembrolizumab improves survival compared with platinum-doublet chemotherapy. Whether higher PD-L1 levels within the expression range of 50%-100% predict for even greater benefit to pembrolizumab is currently unknown. PATIENTS AND METHODS In this multicenter retrospective analysis, we analyzed the impact of PD-L1 expression levels on the overall response rate (ORR), median progression-free survival (mPFS), and median overall survival (mOS) in patients who received commercial pembrolizumab as first-line treatment of non-small-cell lung cancer (NSCLC) with a PD-L1 expression of ≥50% and negative for genomic alterations in the EGFR and ALK genes . RESULTS Among 187 patients included in this analysis, the ORR was 44.4% [95% confidence interval (CI) 37.1% to 51.8%], the mPFS was 6.5 months (95% CI 4.5-8.5), and the mOS was not reached. The median PD-L1 expression level among patients who experienced a response to pembrolizumab was significantly higher than among patients with stable or progressive disease (90% versus 75%, P < 0.001). Compared with patients with PD-L1 expression of 50%-89% (N = 107), patients with an expression level of 90%-100% (N = 80) had a significantly higher ORR (60.0% versus 32.7%, P < 0.001), a significantly longer mPFS [14.5 versus 4.1 months, hazard ratio (HR) 0.50 (95% CI 0.33-0.74), P < 0.01], and a significantly longer mOS [not reached versus 15.9 months, HR 0.39 (95% CI 0.21-0.70), P = 0.002]. CONCLUSION Among patients with NSCLC and PD-L1 expression of ≥50% treated with first-line pembrolizumab, clinical outcomes are significantly improved in NSCLCs with a PD-L1 expression of ≥90%. These findings have implications for treatment selection as well as for clinical trial interpretation and design.

Abstract
Background
High sensitive cardiac troponin I (hs-TnI), subunit of cardiac troponin complex, is a sensitive and specific marker of myocardium injury as troponin T. Several studies showed hs-TnI was associated with worse cardiovascular outcomes but relationship between serum hs-TnI level in patients with atrial fibrillation (AF) after pulmonary vein isolation (PVI) and AF recurrence remains unclear.
Methods
We enrolled 444 consecutive AF patients who underwent PVI from May 2017 to September 2018. We investigated the difference of relationship between serum hs-TnI, inflammation markers at 48 hours after PVI and early or late recurrence of AF (ERAF, <3 months and LRAF, during 1 year after PVI in patients with AF) between radiofrequency ablation (RFA) group and cryoballoon ablation (CBA) group.
Results
RFA and CBA were performed in 328 and 116 patients, respectively. There were no significant differences in patient characteristics between RFA group and CBA group. Serum hs-TnI in RFA group was significantly lower than in CBA group (1.93 ng/ml±3.28 vs 5.08 ng/ml±4.29, p<0.001), while hs-CRP was significantly higher in RFA group than CB group (1.97±2.38 mg/dl vs 1.10±0.84 mg/dl, p<0.001). The incidence of ERAF was similar between the two groups (RFA group: 26.8% and CBA group: 21.6%, p=0.262). There was no significant difference of hs-TnI and hs-CRP between patients with ERAF and without ERAF (table). In 213 patients who were followed during 1 year (PVIs were performed from May 2017 to January 2018, RFA 149 and CBA 64 patients), there was no significant association between hs-TnI, hs-CRP and incidence of LRAF (table).
TnI and CRP between RFA and CBA RFA (n=328) CBA (n=116) P value hs-TnI 1.93±3.28 5.08±4.29 <0.001 hs-CRP 1.97±2.38 1.10±0.84 <0.001 3 months follow-up RFA (n=328) CBA (n=116) ERAF (+) ERAF (−) P value ERAF (+) ERAF (−) P value hs-TnI 1.68±1.90 2.02±3.66 0.410 5.03±3.17 5.10±4.56 0.943 hs-CRP 2.23±2.65 1.88±2.27 0.238 1.01±0.84 1.13±0.85 0.524 1 year follow-up RFA (n=149) CBA (n=64) LRAF (+) LRAF (−) P value LRAF (+) LRAF(−) P value hs-TnI 1.61±1.77 1.87±2.69 0.570 4.71±2.14 5.60±5.69 0.664 hs-CRP 2.18±2.24 1.92±2.24 0.550 1.12±0.64 1.12±0.98 0.991
Conclusion
CBA may cause more myocardial injury than RFA, on the contrary RFA may cause more inflammation than CBA. These markers did not affect ERAF and LRAF after PVI.

Abstract
An 83-year-old woman received 8 courses of chemotherapy(mogamulizumab)for adult T cell leukemia in the hematolo- gy department of our hospital, after which she achieved complete remission and was followed up with chemotherapy(VP/ MST: sobuzoxane/etoposide)as an outpatient. Later, diarrheal symptoms appeared, and detailed examinations led to a diagnosis of cancer of the ascending colon. Although no distal metastasis was found, breast cancer was also revealed in the C area of the right breast. The general status of the patient was favorable; thus, right pectoral muscle-conserving mastectomy and concomitant sentinel lymph node biopsy were performed through laparoscope-assisted extended right hemicolectomy. The postoperative course was favorable, and she was discharged on hospital day 7. The excised tumors were pathologically diagnosed as stageⅠ breast cancer and stage Ⅲa colorectal cancer. Chemotherapy(VP/MST)was administered without adjuvant chemotherapy. Presently, 18 months after surgery, complete remission of adult T cell leukemia has been maintained, without metastasis and recurrence of cancer of the ascending colon and breast cancer.

Abstract
SummaryThe nature of sugar chain of factor VTII/von Willebrand factor in plasma of normal subjects and patients with von Willebrand’s disease (vWd) was examined by crossed affinoimmunoelectrophoresis using anti-human factor VIII rabbit serum, with inserted Ricinus communis agglutinin-120 (RCA-120) agarose layer (RCA – CIE). Molecular weights of factor VlU-related antigen (VIIIR: Ag) were estimated by SDS polyacrylamide gel electrophoresis — crossed affinoimmunoelectrophoresis (SDS PAGE – RCA – CIE).VIIIR :Ag, in normal plasma and in classical form of vWd, showed two precipitin peaks on RCA – CIE. The slower moving component of VIIIR :Ag with molecular weights over 3×106 daltons from normal subjects and patients with classical form of vWd showed a high affinity for RCA-120. The faster moving component of VIIIR: Ag below 3×106 daltons from the abovementioned subjects and patients with a variant form (Type IIA) showed a very weak affinity for RCA-120.These results suggested that all of VIIIR: Ag in these variant cases may have a deficiency of galactose residues reactive with RCA, in addition to an incomplete polymerization of VIIIR: Ag, similar to that of the faster moving component of normal subjects.

Abstract
SummaryPatterns of VIIIR:AG in the plasma and its fractions, cryoprecipitate and cryosupernatant, from various types of von Willebrand’s disease (vWd) were observed by SDS 1.5% polyacrylamide gel electrophoresis - crossed immunoelectrophoresis (SDS PAGE - CIE).
VIIIR:AG in normal cryoprecipitate showed several precipitin peaks which correspond to molecular weights ranging from 8 X 105 to 1 X 10
7 daltons and are similar to those in normal plasma. Normal cryosupernatant VIIIR: AG gave smaller molecular weights from 8 X 10
5 to 2 X 10
6 daltons.VIIIR:AG in the plasma and cryoprecipitate from 2 patients with classical vWd gave low precipitin peaks with molecular weights in normal range. VIIIR:AG from 2 patients with subgroup A variant which showed fast anodal migration on the conventional CIE, presented 3 peaks with molecular weights of 8 X 105 to 3 X 106 which are similar to those in normal cryosupernatant. VIIIR: AG from 2 patients with subgroup B variant which showed normal migration on the CIE, gave normal patterns through all fractions.

Abstract
SummaryThe cloning of the cDNA encoding von Willebrand factor (vWF) has revealed that it is synthesized as a large precursor (pre-pro-vWF) molecule and it is now clear that the prosequence or vWAgll is responsible for the intracellular multimerization of vWF. We have cloned the complete vWF cDNA and expressed it using a recombinant vaccinia virus as vector. We have characterized the structure and function of the recombinant vWF (rvWF) secreted from five different cell types: baby hamster kidney (BHK), Chinese hamster ovary (CHO), human fibroblasts (143B), mouse fibroblasts (L) and primary embryonic chicken cells. Forty-eight hours after infection, the quantity of vWF antigen found in the cell supernatant varied from 3 to 12 U/dl depending on the cell type. By SDS-agarose gel electrophoresis, the percentage of high molecular weight forms of vWF varied from 39 to 49% relative to normal plasma for BHK, CHO, 143B and chicken cells but was less than 10% for L cells. In all cell types, the two anodic subbands of each multimer were missing. The two cathodic subbands were easily detected only in BHK and L cells. By SDS-PAGE of reduced samples, pro-vWF was present in similar quantity to the fully processed vWF subunit in L cells, present in moderate amounts in BHK and CHO and in very low amounts in 143B and chicken cells. rvWF from all cells bound to collagen and to platelets in the presence of ristocetin, the latter showing a high correlation between binding efficiency and degree of multimerization. rvWF from all cells was also shown to bind to purified FVIII and in this case binding appeared to be independent of the degree of multimerization. We conclude that whereas vWF is naturally synthesized only by endothelial cells and megakaryocytes, it can be expressed in a biologically active form from various other cell types.
