Abstract
BACKGROUND & AIMS Relationships of serum C-C motif chemokine ligand 5 (CCL5) and C-X-C motif chemokine ligand 10 (CXCL10) levels with hot immune features have been reported in patients with hepatocellular carcinoma (HCC). Therefore, we examined the utility of their levels for predicting the efficacy of atezolizumab plus bevacizumab (Atez/Bev) in patients with HCC. DESIGN In total, 98 patients with HCC treated with Atez/Bev were enrolled, and their initial responses were evaluated at least once via dynamic computed tomography or magnetic resonance imaging. Serum CCL5 and CXCL10 levels were assessed by enzyme-linked immunosorbent assay before treatment and at the start of the second course of Atez/Bev therapy, and their relationships with treatment efficacy were determined. RESULTS No analyzed factor was associated with the initial therapeutic response. Among the 56 patients with Barcelona Clinic Liver Cancer (BCLC) stage C, serum CXCL10 levels at the beginning of course two (CXCL10-2c) tended to be higher in responders than in non-responders in the initial evaluation, and its optimal cutoff level of 690 pg/mL could be used to stratify patients regarding overall survival (OS; high vs. low: not reached vs. 17.6 months, p = 0.034) and progression-free survival (high vs. low: 13.6 vs. 5.1 months, p = 0.014). In multivariate analysis, high CXCL10 levels and neutrophil-to-lymphocyte ratios at the start of course two and Child-Pugh stage A at baseline were independent predictive factors of improved OS. CONCLUSIONS Serum CXCL10-2c levels were predictive of Atez/Bev efficacy in patients with BCLC stage C HCC.

Abstract
BACKGROUND Olfactory dysfunctions (OD) and taste dysfunctions (TD) are widely recognized as characteristic symptoms of COVID-19; however, the frequency and mode of occurrence has varied depending on the viral mutation. The prevalence and characteristics of OD/TD in Japan have not been definitively investigated. The purpose of this study is to assess the prevalence of OD/TD in Japan during the Alpha variant epidemic, and measure symptom prolongation at 6 months and 1 year later following initial infection. METHODS Patients treated for COVID-19 between February to May 2021 were evaluated for OD/TD symptoms and provided with a QOL questionnaire. Olfactory tests and taste tests were performed using Open Essence and Taste Strips, respectively. RESULTS Among the 251 COVID-19 patients who participated, 119 underwent both olfactory and taste tests. Prevalence of subjective OD and TD at the time of survey was 57.8% and 40.2%, respectively. After 12 months, the prevalence fell to 5.8% for OD and 3.5% for TD. Among the OD/TD patients, 36.6% experienced parosmia, and 55.4% experienced parageusia. Prevalence of parosmia and parageusia was higher at 6 and 12 months than at the time of survey. Patients with long-lasting disease reported qualitative dysfunctions and scored significantly higher in food-related QOL problems. Most patients who were aware of their hyposmia had low scores on the olfactory test (83.1%). In contrast, only 26.7% of patients who were aware of their hypogeusia had low scores on the taste test. CONCLUSIONS The prevalence of COVID-19-related OD and TD at the time of survey was 57.8% and 40.2%, respectively. Subjective symptoms of OD and TD persisted for one year in 5.8% and 3.5% of patients, respectively. More than half of the patients with OD or TD complained of qualitative dysfunction and a decrease in their QOL related to eating and drinking. Most patients with TD did not have true TD, but rather developed flavour disorders associated with OD. This conclusion is supported by the finding that patients with subjective OD had low scores on the olfactory test, whereas most patients with subjective TD had normal scores on the taste test.

Abstract
Metastatic colorectal neuroendocrine carcinoma (NEC) is often treated using a chemotherapy protocol for small-cell lung cancer; however, the prognosis is extremely poor. A 55-year-old woman with BRAF V600E-mutated transverse colon NEC and liver metastases underwent colectomy followed by FOLFOXIRI plus bevacizumab. Consequently, the liver metastases markedly shrank. Owing to later worsening of the liver metastases, she received encorafenib and binimetinib plus cetuximab. Despite discontinuing binimetinib due to myalgia, she had a long-term response with a progression-free survival of 14 months and an overall survival of more than 27 months. A chemotherapy protocol for BRAF-mutated metastatic colorectal cancer may be a treatment option for BRAF V600E-mutated colorectal NEC.

Abstract
Phospholipid-protein interactions play important roles in regulating the function and morphology of photosynthetic membranes in purple phototrophic bacteria. Here, we characterize the phospholipid composition of intracytoplasmic membrane (ICM) from Rhodobacter (Rba.) sphaeroides that has been genetically altered to selectively express light-harvesting (LH) complexes. In the mutant strain (DP2) that lacks a peripheral light-harvesting (LH2) complex, the phospholipid composition was significantly different from that of the wild-type strain; strain DP2 showed a marked decrease in phosphatidylglycerol (PG) and large increases in cardiolipin (CL) and phosphatidylcholine (PC) indicating preferential interactions between the complexes and specific phospholipids. Substitution of the core light-harvesting (LH1) complex of Rba. sphaeroides strain DP2 with that from the purple sulfur bacterium Thermochromatium tepidum further altered the phospholipid composition, with substantial increases in PG and PE and decreases in CL and PC, indicating that the phospholipids incorporated into the ICM depend on the nature of the LH1 complex expressed. Purified LH1-reaction center core complexes (LH1-RC) from the selectively expressing strains also contained different phospholipid compositions than did core complexes from their corresponding wild-type strains, suggesting different patterns of phospholipid association between the selectively expressed LH1-RC complexes and those purified from native strains. Effects of carotenoids on the phospholipid composition were also investigated using carotenoid-suppressed cells and carotenoid-deficient species. The findings are discussed in relation to ICM morphology and specific LH complex-phospholipid interactions.

Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
AIM Minocycline hydrochloride (MINO) aspiration sclerotherapy (AS) has been widely used for treating hepatic cysts (HC). However, cyst recurrence remains problematic. Information on monoethanolamine oleate (EO) AS, another effective HC treatment, is currently limited. We investigated the efficacy of EO on ineffective MINO treatments, and the relationship between MINO AS and cyst fluid pH. METHODS A total of 22 cases with symptomatic HC underwent AS with 500 mg of MINO from January 2016 to June 2021. Cyst fluid pH was measured before and after MINO injection. Cyst volume ratio (CVR, %) after 2 weeks was calculated as follows:cyst volume 2 weeks after MINO injection / pre-treatment cyst volume × 100. Treatment was completed if CVR after 2 weeks was ≤35% (MINO-group). For patients with CVR >35%, 2 g of EO was added (MINO/EO-group). Cyst volume ratio was measured every 12 months thereafter. RESULTS There were no recurrence symptoms in any of the patients during follow-up. Of the 22 cases, 21 had CVR ≤20% after 12 months. The MINO/EO-group (n = 8) tended to have smaller CVRs after 12 months than the MINO-group (n = 14). Cyst volume ratio after 2 weeks was correlated to pH change (p = 0.012) and was larger in patients whose pH decreased by <1.5 (p = 0.015). All adverse events were mild, including in elderly patients. CONCLUSION Adding EO is an effective and safe treatment for symptomatic HC when MINO AS alone is insufficient. Patients with pH decreases of <1.5 should be considered for additional EO treatment.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
AIM Atezolizumab plus bevacizumab (Atez/Bev) therapy is expected to have good therapeutic efficacy for patients with advanced hepatocellular carcinoma (HCC). However, the clinical indicators that predict therapeutic efficacy have not been established. We retrospectively investigated whether the neutrophil-to-lymphocyte ratio (NLR) during Atez/Bev therapy could predict therapeutic efficacy. METHOD In total, 110 patients with HCC were enrolled; they were treated with Atez/Bev therapy and evaluated for their initial response by dynamic CT or MRI at least once between October 2020 and July 2022. RESULTS Of the 110 patients with HCC at the initial evaluation, two (2%) showed a complete response (CR), 22 (20%) partial response (PR), 62 (56%) stable disease (SD), and 24 (21%) progressive disease (PD). The NLR at the start of the second course (NLR-2c) increased from CR + PR to SD to PD. There was no significant association between the baseline NLR and the initial therapeutic response. Patients with CR + PR had lower NLR-2c values than those with SD + PD (p < 0.001) and the optimal cut-off value of NLR-2c was 1.97. Patients with NLR-2c <1.97 had better overall survival and progression-free survival (PFS) than those with NLR-2c ≥1.97 (p = 0.005 for overall survival; p < 0.001 for PFS). A multivariate analysis showed that female sex, higher PIVKA-II levels at baseline, and higher values of NLR-2c were significantly associated with poorer PFS. CONCLUSIONS The NLR-2c value predicts the initial therapeutic response and prognosis of patients with HCC treated with Atez/Bev therapy.

Abstract
AIM We retrospectively investigated patients with administration of nucleos(t)ide analogs (NAs) for prevention of or against hepatitis B virus (HBV) reactivation, and their clinical outcomes after cessation of the NA. METHODS We enrolled 180 patients who were positive for HBsAg when they started immunosuppressive therapy or chemotherapy and an NA was administered to prevent HBV reactivation (HBV carrier group), and 82 patients with resolved HBV infection who started administration of an NA after HBV reactivation (de novo HBV group). Cessation of the NA depended on each physician's judgment without definite criteria. RESULTS A total of 27 patients in the HBV carrier group and 22 in the de novo HBV group stopped NA therapy. In the HBV carrier group, 16 patients experienced virological relapse, which was defined as HBV DNA levels ≥20 IU/ml, and one with hematological disease had an alanine aminotransferase flare after cessation of NA. Of the 16 patients, the NA was reintroduced in three, whereas, the remaining 13 had low levels of HBV DNA and no alanine aminotransferase flare. In the de novo HBV group, virological relapse occurred in six patients, and one with hematological disease had an alanine aminotransferase flare after cessation of the NA. The NA was reintroduced in four of the six patients. CONCLUSIONS We may be able to consider to cease NA therapy proactively in HBV carriers and resolved patients with non-hematological disease, if their primary diseases are under remission after completion of immunosuppressive therapy or chemotherapy. However, careful follow up is necessary after stopping NA therapy.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
Abstract
Background
In patients with VT after myocardial infarction (MI), substrate-based ablation is superior to approaches that target clinical and tolerated VTs only. Different substrate modification strategies have been reported. However, proposed ablation targets are prone to operator interpretation (e.g. abnormal electrograms). Accordingly, ablation results can also be operator dependent. Evoked delayed potentials (EDP) are a well-defined target. Elimination of EDP has been effective to prevent VT recurrence in a retrospective, single center cohort.
Aim
(1)To evaluate the outcome of EDP ablation in a prospective cohort of patients included on an intention-to-treat principle and (2)to assess the outcome of EDP ablation following one uniform protocol when performed in centers without prior experience with this strategy.
Methods
Consecutive patients referred for post-MI VT ablation were prospectively enrolled in one center with extensive experience in EDP ablation and 5 centers with no prior experience. Substrate mapping focused on EDP identification followed a uniform protocol across all centers. In brief, all electrograms located within the infarct area were analyzed during sinus rhythm, RV pacing at a fixed rate and during the application of one short-coupled RV extra-stimulus (S2). Sites showing low-voltage, nearfield electrograms with >10ms delay or block in response to S2 were categorized as EDP and targeted for ablation. After ablation, re-mapping to confirm EDP elimination and a complete stimulation protocol (up to 4 extra's from RV and LV) were performed. Patients were followed for VT recurrence and mortality.
Results
130 patients (69±10 years, 87% men, 42% anterior MI, LVEF 34% (IQR 24–43), 71% NYHA II–III, 42% on amiodarone, 52% ≥1 ICD shock, 22% with electrical storm or incessant VT) were included. The extra-stimulation protocol was systematically conducted in 127 (98%) patients and in 121 (93%), EDPs were identified. EDPs were successfully eliminated in 117/121 (97%) patients. After 23 (IQR 14–35) min of RF, 102 (78%) patients were rendered non-inducible. Median procedural duration was 212 (IQR 179–262) min. During follow-up of 14 (IQR 8–18) months, 36 (28%) patients had VT recurrence and 13 (10%) died or received a LVAD. VT-free survival was 79% (95% CI: 72–86) and 72% (95% CI: 63–80) at 6 and 12 months follow-up. Of note, VT-free survival at 12 month was not significantly different between patients undergoing the procedure in centers with and without prior experience in EDP ablation (76% (95% CI: 61–90) vs. 70% (95% CI: 59–81); P=0.269).
Conclusion
In a large prospective cohort of patients with post-MI VT, substrate ablation based on EDP elimination resulted in excellent long-term outcome. Of importance, procedural outcomes were similar in centers with or without experience in EDP ablation, indicating that this approach can be easily reproduced by operators previously not familiar with the technique.

Abstract
BACKGROUND AND PURPOSE CNS lesions of tuberous sclerosis complex are diagnosed mainly by T2WI, FLAIR, and sometimes T1WI with magnetization transfer contrast. The usefulness of T1WI with chemical shift selective images was recently reported in focal cortical dysplasia type IIb, which has histopathologic and imaging features similar to those of tuberous sclerosis complex. We investigated the usefulness of the T1WI with chemical shift selective images in detecting CNS lesions of tuberous sclerosis complex. MATERIALS AND METHODS We retrospectively reviewed 25 consecutive patients with tuberous sclerosis complex (mean age, 11.9 [SD, 8.9] years; 14 males) who underwent MR imaging including T1WI, T1WI with magnetization transfer contrast, T1WI with chemical shift selective, T2WI, and FLAIR images. Two neuroradiologists assessed the number of CNS lesions in each sequence and compared them in 2 steps: among T1WI, T1WI with magnetization transfer contrast and T1WI with chemical shift selective images, and among T2WI, FLAIR, and T1WI with chemical shift selective images. We calculated the contrast ratio of the cortical tubers and of adjacent normal-appearing gray matter and the contrast ratio of radial migration lines and adjacent normal-appearing white matter in each sequence and compared them. RESULTS T1WI with chemical shift selective images was significantly superior to T1WI with magnetization transfer contrast for the detection of radial migration lines and contrast ratio of radial migration lines. There was no significant difference between T1WI with chemical shift selective images and T1WI with magnetization transfer contrast for the detection of cortical tubers and the contrast ratio of the cortical tubers. Both T2WI and FLAIR were statistically superior to T1WI with chemical shift selective images for the detection of cortical tubers. T1WI with chemical shift selective images was significantly superior to T2WI and FLAIR for the detection of radial migration lines. CONCLUSIONS The usefulness of T1WI with chemical shift selective images in detecting radial migration lines was demonstrated. Our findings suggest that the combination of T1WI with chemical shift selective images, T2WI, and FLAIR would be useful to evaluate the CNS lesions of patients with tuberous sclerosis complex in daily clinical practice.

Background
Patients with ischemic cardiomyopathy (ICM) referred for catheter ablation (CA) of ventricular tachycardia (VT) are at risk for end-stage heart failure (HF) due to adverse remodeling of the left ventricle (LV). Local unipolar voltages (UV) decrease with loss of viable myocardium. A UV mapping derived parameter that corrects for oversampling of the infarct area may reflect the total amount of remaining LV viable myocardium.
Objective
To evaluate if the newly proposed parameter, `area weighted unipolar voltage’ (awUV), can predict HF related death/LVAD/Heart transplant (HFD) in ICM.
Methods
Voltage maps from consecutive patients with ICM referred for CA of VT, were transferred to Paraview after valve area removal. AwUV was calculated by mathematically interpolating all mapping points weighted for relative distances divided by the LV endocardial surface. Unipolar low voltage areas (ULVA, UV<8.27mV) were measured as percentage of the total LV surface. Associations between clinical and mapping derived parameters and HFD (HF-related death/LVAD/heart transplant) were evaluated and validated in a second cohort of consecutive patients.
Results
Eighty-nine patients in the study group (age 68±8; LVEF 33% [IQR 24-40%]; ULVA 64% [IQR 46-86%]; awUV 7.01 [IQR 5.01-8.52]) and 69 patients in the validation group (age 68±9; LVEF 39% [IQR 29-44%]; ULVA 59% [IQR 43-77%]; awUV 7.60 [IQR 6.16-8.69]) were included. Follow-up was 32±17 months in the study group, 28±17 months in the validation group. HFD was 20% in the study group, 10% in the validation cohort. Patients with HFD had lower LVEF and awUV, and larger ULVA than patients without HFD (LVEF 23±10% vs. 35±11%; awUV: 5.12±1.92 vs. 7.75±2.64; LVA 86±21% vs. 60±23%, all P<0.001). Univariable analysis showed that LVEF, ULVA and awUV were associated with HFD (HR and 95% CI: LVEF 1.10 [1.05 – 1.16]; LVA 1.05 [1.02 – 1.08]; awUV 2.18 [1.58 – 3.40], all P<0.01). AwUV was superior to ULVA to predict HFD in likelihood ratio calculations (awUV: LR 5.66, P=0.02; LVA: 1.76 P=0.18) and ROC analysis (AUC awUV: 0.86; LVA 0.78). The optimal cut-off for awUV of<5.27 was highly accurate to predict HFD in the validation cohort (log-rank P<0.001).
Conclusion
The newly proposed parameter awUV, easily available from routine voltage mapping, may be useful at identifying ICM patients at risk for HFD.

Background
Patients with repaired tetralogy of Fallot (rTOF) remain at risk of sudden cardiac death due to reentrant sustained monomorphic ventricular tachycardia (SMVT). Slow conducting anatomical isthmuses (SCAI), in particular SCAI3 at the outlet septum, bordered by the pulmonary annulus and the ventricular septal defect patch, are the dominant substrate for SMVT. Electroanatomical mapping (EAM) is the invasive gold standard to identify SCAIs, and transection of SCAI by catheter ablation has been correlated with favorable long-term outcome. Non-invasive identification of SCAI for risk stratification and treatment planning is needed but has not been established yet. Three-dimensional (3D) late gadolinium-enhanced (LGE) cardiovascular magnetic resonance (CMR) facilitates accurate visualization of morphologically complex hearts with high-spatial resolution.
Objective
The study thought to determine whether 3D LGE-CMR can identify SCAIs.
Methods
Consecutive patients with rTOF who underwent right ventricular (RV) EAM and 3D LGE-CMR were included. LGE-CMR-derived 3D RV reconstructions were created (ADAS-3D) and merged with 3D RV EAM data. Mapping points were superimposed on the CMR-derived 3D reconstruction allowing for direct comparison of EAM data and local signal intensity (SI). The optimal SI cut-off to identify low bipolar voltage (LBV, BV<1.76mV) was determined by receiver operating characteristic carve. An abnormal AI on LGE-CMR was defined as AI with continuous SI above the obtained cut-off connecting AI borders.
Results
Forty-eight rTOF patients (34±16 years, 58% male) were included. At EAM, 21 patients had normal AI, and 20 and 7 had a SCAI (<0.5m/s) or blocked AI, which was AI3 in all. Patients with SCAI showed low BV of AI3 (median 0.7 [range 0.25-2.59] mV). In 11 patients, 14 SMVTs could be induced, all related to SCAI3.
A total of 9240 points were analyzed, showing a significant correlation between BV and SI (R=0.4, P<0.001). The optimal SI cut-off to identify LBV was 42% of the maximal SI (MSI) (AUC 0.80; sensitivity, 74%; specificity, 78%). Using this cut-off of MSI, a SCAI or blocked AI3 could be correctly identified by LGE-CMR in all 27 patients, and a normal AI3 could be correctly confirmed by LGE-CMR in 14/21 patients with normal EAM findings (Figure). The sensitivity and specificity of 3D LGE-CMR for identifying SCAI or blocked AI3 were 100% and 67%, respectively. Of note, among patients with normal EAM findings, those with abnormal AI3 on LGE-CMR had significantly lower BV of AI3 than those with normal AI3 on LGE-CMR (2.06 [Range, 1.62-2.60] vs. 3.53 [2.22-5.67] mV, P<0.01).
Conclusion
3D LGE-CMR can identify SCAI with 100% sensitivity and may identify diseased AI3 even before critical conduction delay occurs. This technique may allow for non-invasive risk stratification of VT and can refine patient selection for invasive EAM.

[Purpose] Phase angle (PhA) by BIA was studied as muscle function in various diseases. However the effects of nutrition states to phase angle is unclear especially in cardiac patients. This study examined the relationship between PhA, physical function and nutritional index in patients with heart disease.
Methods
PhA was measured using InBody770 for 33 heart disease patients (age: 71.6 ± 13.4 years, EF: 58.6 + 11.0%) who underwent cardiac rehabilitation during hospitalization. Short Physical Performance Battery (SPPB) was performed for physical function evaluation, and ALB, eGFR, and NT-ProBNP were evaluated for blood tests. calorie intake and GNRI were calculated as nutritional assessments.
Results
PhA was 4.1 ± 0.9 °. PhA has a positive correlation with SMI (r = 0.62), chair rise time (r = 0.62), dietary calorie intake (r = 0.49), GNRI (r = 0.50), NT-ProBNP (r = -0.631), ECW A negative correlation was found with / TBW (r = -0.91). As a result of multiple regression analysis with PhA as the dependent variable, ECW / TBW (β = -0.73), SMI (β = 0.33), and chair rise time (β = 0.10) were extracted as significant independent factors (β = -0.13). r² = 0.96).
[Conclusion] PhA in patients with heart disease was correlated with physical function and nutritional index, and a significant independent factor was physical function. In particular, lower limb muscle strength was extracted independently of extracellular water ratio and muscle mass. These results suggest that PhA may be a comprehensive index of physical function in cardiac patients.

Objectives
Angiopoietin-like protein 2 (ANGPTL2) is a protein, whose structure is similar to that of angiopoietin, but binds to a different receptor. Overexpression of ANGPTL2 promotes chronic inflammation and relates to the development of aging-related diseases. ANGPTL2 has been reported to be mainly secreted by adipose tissue. Although ANGPTL2 has been implicated in the pathogenesis of heart failure, there are no studies about serum ANGPTL2 levels in patients with heart failure participating in cardiac rehabilitation program. The aim of this study was to investigate the characteristics, related factors and changes of ANGPTL2 in patients with chronic heart failure during phase III of cardiac rehabilitation program.
Methods
The subjects included 57 patients (70.1 ± 10.2 years old; 46 men) with chronic heart failure whose serum ANGPTL2 levels were measured during the maintenance phase of cardiac rehabilitation program. Furthermore, we classified 25 patients (70.6 ± 7.5 years old; 23 men) from the 6-month course into a reduced group and an unchanged group to characterize change in ANGPTL2. We excluded patients who were admitted or discharged within 3 months of the evaluation of serum ANGPTL2. We evaluated exercise tolerance using the cardiopulmonary exercise test, grip strength, body composition using a body composition analyzer, blood examinations, and echocardiography. Serum ANGPTL2 was measured by solid-phase sandwich enzyme-linked immunosorbent assay (ELISA).
Results
The median value of ANGPTL2 was 4.05 ng/ml. ANGPTL2 was positively correlated with body weight, body mass index, body fat mass, body fat percentage, C-reactive protein (CRP) and total protein (TP) levels, and negatively correlated with skeletal muscle mass percentage and anaerobic threshold (AT). From the result of the logistic regression analysis, AT (OR=0.68, 95% CI:0.47-0.97and TP (OR=20.1, 95% CI:2.52-160.63) were extracted as independent factors related to the level of ANGPTL2. In addition, overall serum ANGPTL2 levels decreased significantly after 6 months. Changes in ANGPTL2 in the reduced group showed a positive correlation between baseline peak VO2, left ventricular ejection fraction and skeletal muscle rate, and a negative correlation with baseline ANGPTL2, CRP, body fat mass. In an unchanged group, HbA1c increased, but no significant change was observed in other factors.
Conclusions
Exercise tolerance in patients with chronic heart failure during maintenance phase might be related to the inflammation marker ANGPTL2. Serum ANGPTL2 levels with stable chronic heart failure patients decreased significantly 6 months after continued cardiac rehabilitation.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
This study's objective was to explore the association between various factors and the increased caregiver burden of informal caregivers during the COVID-19 pandemic. On February, 2021, 700 informal caregivers completed an online survey. We assessed the change in caregiver burden during the COVID-19 pandemic. Among all caregiver participants, 287 (41.0%) complained of an increased caregiver burden due to the COVID-19 pandemic. The factors associated with increased caregiver burden were depressive symptoms in caregivers [odds ratio (OR), 2.20; 95% confidence interval (CI), 1.50-3.23], dementia (OR, 2.48; 95%CI, 1.07-5.73) and low Barthel Index scores (OR, 2.01; 95%CI, 1.39-2.90) in care receivers, care days (OR, 1.09; 95%CI, 1.01-1.17) and times (OR, 1.06; 95%CI, 1.01-1.10), and use of home care service (OR, 1.46; 95%CI, 1.01-2.10) and visiting care service (OR, 1.71; 95%CI, 1.20-2.45). These findings suggest we need to pay attention to the physical and mental health of both the care receivers and caregivers.

Abstract
The Japanese guidelines for the treatment of gastric cancer recommend nivolumab as third-line chemotherapy for metastatic gastric cancer. We report a case of gastric cancer exhibiting a durable response after the discontinuation of nivolumab due to the early onset of immune-related adverse event (irAE). A 64-year-old man with advanced HER2-positive gastric cancer and distant lymph node metastasis received nivolumab as fourth-line therapy. After two courses of nivolumab, the lymph nodes showed progression. However, the treatment was discontinued because of interstitial pneumonia as an irAE. Disease regression was sustained for approximately 11 months without the readministration of nivolumab.

Abstract
To determine the genotypes and zoonotic potentials of G. duodenalis isolates from different populations of domestic dogs in Japan, a total of 114 Giardia positive samples were examined using multilocus genotyping analysis at the 3 loci of glutamate dehydrogenase (gdh), beta-giardin (bg), and triose phosphate isomerase (tpi). Although the dog-adapted assemblages C and D were dominant, the zoonotic assemblage A was also demonstrated at a percentage of 23.7% (27/114). The results suggest that canine G. duodenalis isolates in Japan have the potential for zoonotic transmission

Abstract
Abstract
Background
Autotaxin (ATX) has been reported to promote myocardial inflammation and subsequent cardiac remodeling through lysophosphatidic acid (LPA) production. However, the prognostic impact of ATX has not been clarified in dilated cardiomyopathy (DCM).
Purpose
We aimed to investigate the prognostic impact of ATX in patients with DCM.
Methods
We enrolled 104 DCM patients (49.8 years, 76 males). The subjects underwent blood sampling, echocardiography, cardiac catheterization, and endomyocardial biopsy. Gender differences in serum ATX levels have been reported, thus we divided the subjects into two groups using median serum ATX levels for men and women: High-ATX group and Low-ATX group. All patients were followed up by expert cardiologists. The cardiac event was defined as a composite of cardiac death and hospitalization for worsening heart failure.
Results
Eighty-nine percent of the subjects were classified as New York Heart Association functional class I or II. Female patients had higher serum ATX levels than male patients, with median values of 257.0 ng/mL and 203.5 ng/mL, respectively (Figure A). The average left ventricular ejection fraction and brain natriuretic peptide levels were 30.6% and 122.5 pg/mL. In survival analysis, cumulative event-free probability was significantly lower in High ATX group (p=0.007, Figure B). In Cox proportional hazards analysis, High-ATX was one of the independent predictors of composite cardiac events (Hazards Ratio, 2.575; p=0.043). On the other hand, high sensitive C-reactive protein and collagen volume fraction in myocardial samples were not significant predictors.
Conclusion
High serum ATX level was associated with poor prognosis in patients with DCM.

Abstract
Abstract
Background
The spleen is an important organ that stores blood, releases erythrocytes or monocytes, and destroys no-longer-needed platelets. It can reserve 20–30% of the total blood volume, and its size is reduced in hypovolemic shock. However, the clinical significance of the spleen size in patients with heart failure (HF) remains unclear.
Purpose
The purpose of this study was to investigate the relationship between spleen size, hemodynamic parameters, and prognosis in patients with HF.
Methods
A total of 219 patients with clinically stable HF were enrolled. All patients underwent right heart catheterisation and computed tomography. The spleen size was measured using computed tomography volumetry. In addition, spleen volume was assessed using the spleen volume index (SVI), corrected for body surface area. Cardiac events were composite endpoints of cardiac death, hospitalisation for worsening HF, fatal arrhythmias, implantation of cardiac devices, implantation of left ventricular assist devices, and unexpected percutaneous coronary intervention or cardiac surgery. Spearman's rank correlation coefficient was used to examine the relationship between spleen volume and hemodynamic parameters. Multivariate Cox hazard regression models were used to investigate whether SVI was an independent determinant of cardiac events.
Results
Of the 219 patients (median age, 54 [interquartile range] 46–64 years), 145 (66%) were males. The median (interquartile range) spleen volume and SVI was 118.0 (91.5–156.0) mL and 67.8 (54.9–87.2) mL/m2, respectively. SVI was positively correlated with cardiac output (r=0.269, P<0.001), and negatively correlated with systemic vascular resistance (r=−0.302, P<0.001) (Figure 1). A total of 70 cardiac events were observed, and the optimal cut-off value of SVI for cardiac events was 68.9 mL/m2 in the receiver operating characteristic analysis. Patients were divided into two groups: low-SVI (n=107, <68.9 mL/m2) and high-SVI groups (n=112, ≥68.9 mL/m2). Blood adrenaline concentration was higher in the low-SVI group than in the high-SVI group (0.039 [0.020–0.057] ng/mL vs 0.026 [0.014–0.044] ng/mL, P=0.004). The low-SVI group had more cardiac events than the high-SVI group (log-rank test, P<0.001) (Figure 2). In the multivariate Cox proportional hazard model, the low-SVI group was an independent predictor of cardiac events, even when adjusted for the conventional validated HF risk score, blood catecholamine levels, and hemodynamic parameters.
Conclusion
The spleen size may affect the prognosis in patients with HF, reflecting haemodynamics, including systemic circulating blood volume status and sympathetic nerve activity.

Abstract
Abstract
Background
Left ventricular reverse remodeling (LVRR) is an important predictor for a good prognosis in patients with dilated cardiomyopathy (DCM). Previous reports indicated the pulmonary artery diameter (PAD) to ascending aortic diameter (AoD) ratio as a predictor of adverse outcomes in heart failure patients. However, the impact of the PAD/AoD ratio for predicting LVRR in patients with DCM is unknown.
Aim
The aim of this study is to investigate the association between PAD/AoD ratio and LVRR in patients with DCM.
Methods
From a prospective study, clinically stable DCM patients who were investigated the LVRR on echocardiography and underwent CT at baseline were enrolled. LVRR is defined as left ventricular (LV) ejection fraction increase of 10% and a decrease in indexed LV end-diastolic diameter of 10% compared to those at baseline. PAD and AoD data was collected with nonenhanced computed tomography images at baseline.
Results
In sixty-nine patients (mean age 50.0±13.3 years), the mean LV ejection fraction was 29.8%, and mean LV end-diastolic dimension was 64.5mm, and both of which data was no significant difference between patients with or without LVRR. LVRR was observed in 23 (33.3%) patients. The PAD/AoD ratio was significantly lower in patients with LVRR than without LVRR (81.4% vs. 92.4%, p=0.003). By ROC analysis, the best cut-off for the detection of LVRR was found for a PAD/AoD ratio of 0.9. From multivariate analyses, PAD/AoD ratio was identified as a significant predictor of LVRR. After a median follow-up duration of 2.5 years, the DCM patients with PAD/AoD≥0.9 revealed a significant higher cardiac event than those with PAD/AoD<0.9 (log-rank, p=0.007)
Conclusions
The PAD/AoD ratio is useful for predicting LVRR in patients with DCM. The DCM patients with high PAD/AoD ratio had a poor long-term outcome.

Abstract
PURPOSE The standard first-line treatment for human epidermal growth factor receptor type 2 (HER2)-positive advanced gastric cancer (AGC) is trastuzumab in combination with cisplatin and fluoropyrimidines. We evaluated the efficacy and safety of S-1 and oxaliplatin (100 mg/m2) (SOX100) combined with trastuzumab, a monoclonal antibody against HER2 for HER2-positive AGC. METHODS In this single-arm, multicenter phase II study, patients with HER2-positive AGC received S-1 (80-120 mg per day) orally on days 1-14, oxaliplatin (100 mg/m2) intravenously on day 1, and trastuzumab (8 mg/kg on day 1 of the first cycle, followed by 6 mg/kg every 3 weeks) intravenously. The primary end point was 1-year survival rate. The secondary end points included overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and safety. RESULTS A total of 25 patients from six centers were enrolled from December 2015 to March 2020. In the 25 patients evaluable for analysis, the 1-year survival rate was 70.8% [90% confidence interval (CI) = 55.5-86.1%], whereas the median OS, PFS, and ORR were 17.8 (95% CI 10.5-22.9) months, 7.6 (95% CI 5.0-10.9) months, and 75.0% (95% CI 53.3-90.2), respectively. Major grade 3/4 adverse events included anorexia (20%), anemia (16%), peripheral sensory neuropathy (16%), and diarrhea (15%). CONCLUSION SOX100 combined with trastuzumab was effective with a favorable safety profile in patients with HER2-positive AGC.

Abstract
Osteoclasts are large, multinucleated, bone-absorbing cells and play a crucial role in osteolytic bone diseases such as osteopetrosis and rheumatoid arthritis. Therefore, controlling osteoclast differentiation and activation has been considered a promising strategy to prevent and treat osteolytic diseases. In this study, we demonstrate, using the mouse monocyte-derived macrophage-like cell line RAW 264, that extract from Nasturtium officinale or watercress, an herb of European origin, suppresses receptor activator of nuclear factor-κB ligand-induced osteoclast differentiation in vitro . N. officinale extract decreased the emergence of tartrate-resistant acid phosphatase-positive differentiated multinuclear cells and inhibited their bone-absorbing activity. The extract decreased expression of genes associated with osteoclast differentiation and function. Induction of nuclear factor of activated T cells c1 (NFATc1), the master transcriptional regulator of osteoclastogenesis, was blunted by N. officinale extract. Activation of nuclear factor-κB and mitogen-activated protein kinases pathways, both of which are necessary for NFATc1 induction and osteoclast differentiation, was also suppressed by the extract. Among upstream kinases, activity of IκB-kinase β (IKKβ), but not that of TGFβ-activated kinase 1, was inhibited by N. officinale extract in vitro. Pharmacological inhibition of IKKβ by a specific inhibitor PS1145 in RAW 264 cells mostly recaptured the inhibitory action of N. officinale extract. These findings provide a novel pharmacological action of N. officinale and its potential usefulness for the prevention of osteoporosis.

Background
Compared to ICM patients, subgroups of DCM patients show higher VT recurrence rates after catheter ablation (CA), despite similar percentages of acute non-inducibility. Pleomorphic VTs (PL-VT) have been reported in ICM patients with fibrotic remodeling and progressive heart failure. Diffuse fibrosis is the dominant scar pattern in DCM. In these patients PL-VT may occur independent of cardiac function.
Aim
To investigate the prevalence, relation with cardiac function, and impact of PL-VT on long-term ablation outcome in patients with ICM and DCM.
Methods
Consecutive patients with ICM or DCM undergoing VT ablation (ICM 2009-2016; DCM 2008-2018) were included. PL-VT was defined as ≥1 spontaneous change of the 12-lead VT morphology lasting for ≥6 consecutive beats during the same induced VT episode. Complete procedural success was defined as non-inducibility of any VT at the end of the procedure. Patients were followed for VT recurrence and mortality.
Results
A total of 247 patients (86% men, age 63 ± 13 years) underwent CA for monomorphic VT, 152 with ICM (62%), and 95 with DCM (38%). Complete procedural success was achieved in 39% in ICM vs. 37% in DCM, respectively. PL-VT was observed in 22 and 29 patients with ICM and DCM, respectively (14% vs. 31%, P = 0.003). Among ICM patients, PL-VT was associated with a lower LVEF (PL-VT+ 28 ± 9% vs. PL-VT- 34 ± 12%, P = 0.02) and only occurred if LVEF was <40%. In contrast, in DCM patients, PL-VT was not related to cardiac function and occurred in 27% of patients with an EF >40%. After propensity score matching to account for baseline differences (age, gender, LVEF, prior VT ablation, VT storm, and amiodarone use), between ICM vs. DCM patients, the PLVT incidence was 4 times higher in DCM patients (7% [4/60] vs. 28% [17/60], P = 0.003).
During a median follow-up of 30 months, 79 (32%) patients died (ICM 48 [32%), DCM 31 [33%], P = 0.88) and 120 (49%) patients had VT recurrence (ICM 59 [39%], DCM 61 [64%], P < 0.001). In Kaplan-Meier analyses, inducibility of PL-VT was associated with mortality only in ICM but not in DCM patients. In contrast, PL-VT was associated with poorer VT-free survival in both ICM and DCM patients (figure). In multivariate analyses, PL-VT remained a significant predictor of VT recurrence in DCM (HR 3.00, 95% CI 1.75-5.11, P < 0.001), independent of LVEF, (likely) pathogenic genetic mutation, amiodarone, endocardial low bipolar/unipolar voltage areas, dominant anteroseptal substrate, and non-complete acute procedural success, but not in ICM.
Conclusions
PL-VT was associated with poor systolic function and mortality in ICM, whereas it was independent of LVEF and the most decisive parameter for VT recurrence in DCM. This data suggests that PL-VT in DCM is a marker of a complex arrhythmic substrate challenging to control by CA. Abstract Figure. Kaplan-Meier analyses

Background
Patients with dilated cardiomyopathy (DCM) and ventricular tachyarrhythmias (VT) are at risk for heart failure (HF) death. Global left ventricular endocardial voltage may reflect the amount of excitable viable myocardium and identify patients at risk for rapid progression to end-stage HF.
Aim
To determine if volume-weighted endocardial voltage, as a surrogate for the total excitable viable myocardium, predicts mortality in patients with DCM and VT.
Methods
Consecutive patients with DCM, who underwent high-density endocardial voltage mapping for VT or PVC ablation (2012-2018), were included. Mapping data were transferred from CARTO to ParaView after excluding valve areas. The volume-weighted UV and BV (vwUV, vwBW) were calculated by mathematically integrating the UV and BV over the whole LV (thereby correcting for mapping density heterogeneity) divided by the endocardial LV surface area and corrected for LV wall thickness determined by echocardiography. The prognostic values of vwUV and vwBV for cardiac function and cardiac death were evaluated.
Results
One hundred three patients (VT, n = 83 and PVC, n = 20; age, 57 ± 14yrs; LVEF, 39 ± 13%; [likely] pathogenic genetic variants 33 [32%]; amiodarone use 36 [35%]) were included. VwUV and vwBV were 9.94 ± 3.42 and 4.70 ± 1.46. During a median follow-up of 24 months, cardiac mortality was 18% (end-stage HF 16/19, the median time to death 5.7 months). Patients who died had a significantly lower vwUV and vwBV (vwUV 5.62 ± 0.93 vs. 10.91 ± 3.10, P < 0.001; vwBV 2.99 ± 0.70 vs. 5.04 ± 1.28, P < 0.001). The optimal cutoff of vwUV for predicting HF-related death was 6.64 (AUC, 0.98; Sensitivity, 94%; Specificity, 95%), superior to LVEF or vwBV (AUC, 0.77, 0.92, respectively, Figure A). In multivariable analysis, vwUV remained the only significant predictor for cardiac death (for one decrease, HR 2.66, CI 1.41-5.00, P = 0.002), independently of LVEF, NT-proBNP, vwBV, genetic variants, and amiodarone use. In a subanalysis, the correlations between vwUV and changes of LVEF over time after voltage mapping were analyzed in patients with mid-range (HFmrEF, EF40-49%, n = 27) and reduced (HFrEF, EF < 40%, n = 53) LVEF, respectively. In patients with HFmrEF, a significant LVEF deterioration (defined as an EF decrease >5% and transition to HFrEF) occurred in 22% and was strongly related with a low vwUV (6.65 ± 1.15 vs. 10.08 ± 2.92, P = 0.02, Figure B left). Furthermore, in patients with HFrEF, a significant LVEF improvement (defined as an EF increase >5% and transition to HFmrEF) was noted in 32% and was correlated with a high vwUV (11.68 ± 2.70 vs. 8.62 ± 2.69, P = 0.002, Figure B right).
Conclusion
VwUV is a newly proposed surrogate for the amount of LV viable myocardium, available from routine endocardial mapping and an excellent parameter to identify patients with DCM at high risk for rapid progression to HF-related death. Abstract Figure. vwUV and outcomes

Abstract

Background
Occurrence of ventricular tachycardias (VT) has been related to changes in sympathetic innervation and myocardial tissue in ischemic cardiomyopathy. In non-ischemic cardiomyopathy (NICM) patients with VT, the relation between global cardiac sympathetic innervation and non-ischemic fibrosis is less clear. The current gold standard in electrophysiology to identify non-ischemic fibrosis relies on unipolar endocardial voltage mapping.
Objective
To establish the relationship between global cardiac sympathetic innervation and global fibrosis.
Methods
29 patients (93% male, 58 ± 14 years, mean LVEF 38%±13) from the ‘Leiden Nonischemic Cardiomyopathy Study’ undergoing VT ablation between 2011-2018 were included. Endocardial voltage mapping was performed and the mean endocardial unipolar voltage (UV) was taken as a surrogate for global fibrosis. Global cardiac sympathetic innervation was analyzed by 123-I-MIBG imaging using heart-to-mediastinum ratio (HMR). A cut-off of 1.8 was used to delineate between normal (>1.8) and denervated (<1.8). HMR was correlated with mean UV.
Results
For patients with global cardiac sympathetic denervation a linear relationship was present between HMR and mean UV (R = 0.5278, P = 0.0431. There was no significant linear relationship for patients with normal cardiac sympathetic innervation between HMR and mean UV (R=-0.1696, P = 0.5795).
Conclusion
Global cardiac sympathetic denervation is related to myocardial fibrosis in patients with NICM and VT. The data support an interplay between denervation and fibrosis which may contribute to arrhythmogeneity, as observed in ICM. Abstract Figure.

Background
Among patients with non-ischemic cardiomyopathy (NICM) two dominant ventricular tachycardia (VT) substrate locations, namely anteroseptal (AS) and inferolateral (IL), have been identified. The poor outcome after catheter ablation of AS substrates (ASS) compared to IL substrates (ILS) has been attributed to its deep intramural location. However, region specific tissue charateristics, including sympathetic innervation, as important determinant of arrhythmogeneity, may also contribute to the outcome disparity.
Aim
To evaluate the association between regional sympathetic denervation, myocardial fibrosis and VT substrates according to two dominant VT substrate locations.
Methods
Twenty-nine patients from the ‘Leiden Nonischemic Cardiomyopathy Study’, who underwent electroanatomical substrate mapping and radiofrequency catheter ablation (RFCA), LGE-CMR and 123-I-MIBG imaging between 2011-2018 were included. The 16-segment model was used to describe the distribution of endocardial low unipolar voltage (UV <25th IQR) (=electroanatomical surrogate for fibrosis), the location of abnormal local electrograms and VT related sites (= surrogate for VT substrate) and the presence of LGE. Regional cardiac sympathetic innervation was determined by 123-I-MIBG imaging and analyzed according to the 16-segment model. Regions with sympathetic denervation were correlated with low UV areas, VT substrate location and LGE. Patients were categorized according to the dominant VT substrate location in ASS or ILS.
Results
Ten patients had a dominant ASS, 12 patients a dominant ILS and 1 patient had ASS and ILS; 6 patients had other VT substrate locations. All but one patient with ASS and one with ILS also showed corresponding low UV (=surrogate for fibrosis) in segments with VT substrates. Eight patients with IL VT substrates but only 4 with AS substrates showed corresponding LGE in the VT related segments. All patients with inferolateral VT substrates showed sympathetic denervation in IL segments (100% matching segments), but only 3/11 (27%) with anteroseptal substrates had sympathetic denervation in AS segments (P = 0.0002). UV was not significantly different between matching (VT substrate and denervation) and not matching ASS segments (5.74 ± 2.69 mV vs. 4.64 ± 1.85 mV, P = 0.78) and between matching ASS and ILS segments (5.74 ± 2.69 mV vs. 7.61 ± 2.91, P = 0.43). LGE location was matching with sympathetic denervation in all patients with ILS but only in 33% of patients with ASS.
Conclusion
Despite low endocardial UV (=surrogate for fibrosis) for AS and IL segments harboring VT substrates, regional sympathetic denervation coincided with fibrosis only for IL VT substrates. The mismatch between regional fibrosis and preserved innervation for AS VT substrates may contribute to a VT substrate difficult to control by RFCA.

Abstract
The core light-harvesting complexes (LH1) in bacteriochlorophyll (BChl) b-containing purple phototrophic bacteria are characterized by a near-infrared absorption maximum around 1010 nm. The determinative cause for this ultra-redshift remains unclear. Here, we present results of circular dichroism (CD) and resonance Raman measurements on the purified LH1 complexes in a reaction center-associated form from a mesophilic and a thermophilic Blastochloris species. Both the LH1 complexes displayed purely positive CD signals for their Qy transitions, in contrast to those of BChl a-containing LH1 complexes. This may reflect differences in the conjugation system of the bacteriochlorin between BChl b and BChl a and/or the differences in the pigment organization between the BChl b- and BChl a-containing LH1 complexes. Resonance Raman spectroscopy revealed remarkably large redshifts of the Raman bands for the BChl b C3-acetyl group, indicating unusually strong hydrogen bonds formed with LH1 polypeptides, results that were verified by a published structure. A linear correlation was found between the redshift of the Raman band for the BChl C3-acetyl group and the change in LH1-Qy transition for all native BChl a- and BChl b-containing LH1 complexes examined. The strong hydrogen bonding and π-π interactions between BChl b and nearby aromatic residues in the LH1 polypeptides, along with the CD results, provide crucial insights into the spectral and structural origins for the ultra-redshift of the long-wavelength absorption maximum of BChl b-containing phototrophs.

Abstract
OBJECTIVES The objective of this study was to investigate the influence of the COVID-19 pandemic on physical activity (PA) and the incidence of frailty among initially non-frail older adults in Japan. DESIGN A follow-up online survey. SETTING AND SUBJECTS Among the 1,600 baseline online survey participants, 388 adults were already frail, and 275 older adults did not respond to the follow-up survey. Thus, the final number of participants in this study was 937 (follow-up rate: 77.3%). METHODS We assessed the total PA time at four time points according to the COVID-19 waves in Japan: January 2020 (before the pandemic), April 2020 (during the first wave), August 2020 (during the second wave), and January 2021 (during the third wave). We then investigated the incidence of frailty during a one-year follow-up period (during the pandemic). RESULTS The total PA time during the first, second, and third waves of the pandemic decreased from the pre-pandemic PA time by 33.3%, 28.3%, and 40.0%, respectively. In particular, the total PA time of older adults who were living alone and socially inactive decreased significantly: 42.9% (first wave), 50.0% (second wave), and 61.9% (third wave) less than before the pandemic, respectively. Additionally, they were at a significantly higher risk of incident frailty than those who were not living alone and were socially active (adjusted odds ratio: 2.04 [95% confidence interval: 1.01-4.10]). CONCLUSION Our findings suggest that older adults who live alone and are socially inactive are more likely to experience incident frailty/disability due to decreased PA during the pandemic. Understanding this mechanism may be crucial for maintaining the health status of older adults.

Abstract
Abstract
Background
Sepsis is a systemic condition of profoundly impaired health in which an infection leads to a dysregulated host response, and consecutively causes organ dysfunction, shock, and even death. Septic cardiomyopathy (SCM) is one of the multiple organ dysfunctions. SCM is typically defined as left ventricular (LV) dysfunction, presented by decreased LV ejection fraction (LVEF). However, it remains unclear about the detailed mechanism of cardiac dysfunction. In addition, the prognostic impact of right heart dysfunction in SCM patients has not been fully investigated.
Purpose
The purpose of this study was to investigate the prognostic impact of right heart dysfunction in patients with SCM.
Methods
We used the MIMIC-III (Medical Information Mart for Intensive Care III) critical care database, which is a large, freely-available database comprising deidentified health-related data associated with over forty thousand patients who stayed in critical care units of the Beth Israel Deaconess Medical Center between 2001 and 2012. We retrospectively analyzed data of patients with septic shock on admission to intensive care unit (ICU). Septic shock was defined as the presence of any suspected infections, the need for vasopressors, and the lactate level exceeding 2 mmol/L, based on the Sepsis-3 criteria. Patients were performed portable transthoracic echocardiography (TTE) during hospitalization. LVEF and right ventricular (RV) function were determined predominately by visual estimation in the parasternal long-axis view. SCM was defined as having a minimum LVEF of 50% or less during hospitalization. Patients with hyperdynamic motion of LVEF >70% were excluded.
Results
In total, there were 2254 patients with septic shock. Of these, 604 patients who underwent TTE were enrolled, and 314 patients were diagnosed with SCM. At baseline, age, gender, Sequential Organ Failure Assessment (SOFA) score, maximum lactate levels, and maximum norepinephrine dosage were 70 [59–79] years, 194 males, 13 [11–15], 4.0 [2.7–6.2] mmol/L, and 0.20 [0.10–0.31] mcg/kg/min, respectively. All patients were treated with vasopressors. In Kaplan-Meier survival analysis, patients with SCM had increased 28-day mortality compared with those without SCM (log-rank, p=0.09). In addition, we divided SCM patients into two groups; SCM with and without RV dysfunction. SCM patients with RV dysfunction had significant increased 28-day mortality compared with those without RV dysfunction (log-rank, p=0.01) (Figure). In Cox proportional hazard regression analysis adjusted for age, male sex, SOFA score, and maximum lactate levels, RV dysfunction was an independent determinant of 28-day mortality (hazard ratio, 1.59; 95% confidence interval, 1.03–2.46; p=0.03).
Conclusions
The presence of RV dysfunction increased 28-day mortality in patients with SCM. It might be useful for predicting the prognosis of SCM to evaluate not only left heart function but also right heart function.

Abstract
Abstract
Background
The spleen has been recognized as an important organ with several functions such as a reservoir of blood volume, and an involvement in iron metabolism by processing of aged red blood cells and recycling iron. During exercise, spleen contracts, and red blood cells pooled in the spleen are recruited into the systemic circulation. So far, we reported that spleen size changed in advanced heart failure (HF) with left ventricular assist device (LVAD). In addition, spleen volume was related to pulmonary capillary wedge pressure (PCWP) or right atrial pressure (RAP) as parameters of cardiac preload. However, it remains unclear about the relationship between spleen volume and exercise capacity in advanced HF with LVAD.
Purpose
The purpose of this study was to investigate the associations between spleen volume and exercise capacity in advanced HF patients with LVAD.
Methods
We enrolled 27 HF patients (21 males, 45±12 years) with LVAD (HeartMate II™; Abbott, Chicago, IL, USA) for use as a bridge to heart transplantation. All patients underwent blood test, echocardiography, right heart catheterization, computed tomography (CT) and cardiopulmonary exercise testing (CPET). Spleen size was measured by CT volumetry. We excluded patients with splenic infarction or aortic valve closure surgery.
Results
At baseline, body mass index, blood brain natriuretic peptide levels, hemoglobin levels, left ventricular ejection fraction were 21.4±3.1 kg/m2, 73.8 (51.9–165.8) pg/mL, 12.1 (10.6–13.4) g/dL, 24.8±14.7%, respectively. Total cardiac output (CO), the sum of pump flow and CO of native heart was 4.6±0.9 L/min, and spleen volume was 184.9±48.8 mL. As for parameters of CPET, peak heart rate (HR), peak VO2, and peak O2 pulse were 128±25 beats/min, 14.2±3.3 mL/kg/min, and 6.6±1.9 mL/beat. At rest, there were significant correlations between spleen volume and PCWP (r=0.382, p=0.049), RAP (r=0.406, p=0.035) or pulsatility index (r=0.384, p=0.047), despite no correlations with total CO or pump flow. During exercise, there were significant interrelations of spleen volume with peak VO2 (r=0.451, p=0.018) and peak O2 pulse (r=0.427, p=0.026). Furthermore, peak VO2 was interrelated with peak HR (r=0.481, p=0.011) or hemoglobin levels (r=0.649, p<0.001). Remarkably, spleen volume was significantly correlated with hemoglobin levels (r=0.391, p=0.043) (Figure). Interpreting these results based on Fick's formula, the proportion of native CO to total CO is very small at rest, but increases during exercise. The spleen during exercise may contribute to increased native CO, especially stroke volume. Moreover, the spleen may be related to both cardiac preload and oxygen carrying capacity, resulting in a significant association between spleen volume and peak VO2.
Conclusion
Spleen volume could be a useful predictor of exercise capacity in advanced HF patients with LVAD, reflecting splenic function to modulate cardiac preload and blood hemoglobin levels.

Abstract
Abstract
Background
Dilated cardiomyopathy (DCM) is characterized by a reduction in left and/or right ventricular myocardial contraction, dilatation of biventricular cavity and major cause of heart failure with high morbidity and mortality rates. Right ventricular dysfunction (RVD) recently have been received attention because of 34% of DCM had RVD and considered as a powerful predictor of impaired prognosis in DCM. Pulmonary Artery Pulsatility index (PAPi) is a novel hemodynamic index shown to predict RVD in advanced heart failure, however, it is unknown that even at early phase, PAPi can reflects latent right myocardial damage and predict long-term prognosis in stable DCM patients.
Methods
From April 2000 to March 2018, we enrolled 566 consecutive patients with cardiomyopathy. All patients underwent laboratory measurement, echocardiography, and cardiac catheterization to evaluate their general conditions. After excluded secondary cardiomyopathy, ischemic cardiomyopathy, and valvular heart disease, finally 162 DCM patients were enrolled. All enrolled patients had NYHA I/II/III and NYHA I/II were 150 patients (92.6%). PAPi was calculated as (systolic pulmonary artery pressure – diastolic pulmonary artery pressure (Pulmonary artery pulse pressure: PAPP)) / right atrial pressure. Median followed up for 4.85 years. In this study 149 patients were performed endomyocardial biopsy in order to exclude secondary cardiomyopathies and 95 patients were assessed using Sirius red staining. Myocardial fibrosis in biopsy specimen was assessed using Sirius red staining, and the positive region was quantified as the collagen volume fraction (CVF).
Results
The mean age and LV ejection fraction (EF) was 50.9±12.6 years and 30.5±8.3%, respectively. When divided into two groups by median PAPi value [PAPi <3.06 (L-PAP) and PAPi ≥3.06 (H-PAP)], even though there were no significant difference in BNP, pulmonary vascular resistance and right ventricular stroke work index between two groups, the probability of cardiac event-survival was significantly higher in L-PAP than H-PAP by Kaplan-Meier analysis (P=0.012). Furthermore, cox proportional hazard regression analysis revealed that PAPi was independent predictor of cardiac events (hazard ratio: 0.624, P=0.025). In pathological analysis, there was no difference between H-PAPi and L-PAPi in CVF.
Conclusion
In the calculation of PAPi, PAPP reflects both RV contractility and left atrial filling pressure and this index considered as RV adaptive response to afterload. The denominator of the PAPP is defined by RA pressure, which serves as a marker of RV preload. Thus, PAPi reflect both preload and afterload of RV at the same time and even though estimated patients at early phase, RVD exists in DCM patients without severe myocardial fibrosis, and PAPi may help stratify DCM and predict cardiac events.

Abstract
Abstract
Background
Balloon angioplasty, including drug-coated balloon (DCB), is an important option of percutaneous coronary interventions (PCI), even in the drug-eluting stent era. Although quantitative coronary angiography (QCA) has been frequently used to determine the optimal endpoint of balloon angioplasty, physiological assessment may add incremental prognostic values. Quantitative flow ratio (QFR) has evolved as a novel 3D QCA-based physiological index to estimate fractional flow reserve without hyperemia nor pressure guidewire, offering both anatomical and functional lesion assessments. This study aimed to characterize post-procedural anatomical and physiological indexes by QFR and to compare their prognostic impacts on long-term clinical outcomes.
Methods
This retrospective study included 98 patients with de novo (n=39) or in-stent restenosis (n=59) lesions who underwent PCI with DCB (n=69) or plain-old balloon angioplasty (POBA, n=29). All lesions were analyzed by QCA and QFR. QCA analysis measured lesion length, reference lumen diameter (RLD), minimum lumen diameter (MLD) and percent diameter stenosis (%DS) at pre- and post-procedures as anatomical indexes. QFR analysis measured post-procedural QFR of target vessel (QFR-vessel) and QFR-gradient (ΔQFR between proximal and distal segments of the lesion) as physiological indexes. Primary endpoint was target lesion revascularization (TLR) within 1-year post-procedure.
Results
Target lesion profiles were as follows: lesion length 26.3±16.6 mm, RLD 2.90±0.70 mm, MLD 0.94±0.32 mm and %DS 79.3±18.6%. At post-procedure, MLD, residual %DS, QFR-vessel and QFR-gradient of target lesions were 1.88±0.49 mm, 34.7±10.6%, 0.84±0.13 and 0.06±0.04, respectively. During 1 year post-procedure, TLR occurred in 19 (19%) patients. Patients with TLR showed smaller MLD (1.66±0.45 mm vs. 1.93±0.49 mm, p=0.028) and QFR-vessel (0.79±0.03 vs. 0.85±0.01, p=0.06), and greater residual %DS (42.7±11.3% vs. 32.8±9.5%, p=0.0002) and QFR-gradient (0.12±0.06 vs. 0.04±0.02, p<0.0001) at post-procedure compared with those without. In multivariate analysis including several clinical characteristics and anatomical indexes, QFR-gradient at post-procedure was independently associated with TLR within 1-year, demonstrating higher prognostic value compared with post-procedural MLD and residual %DS (Figure). The receiver-operating characteristics curve analysis identified the best cut-off value of QFR-gradient as 0.08 for predicting 1-year TLR after balloon angioplasty, irrespective of balloon type (DCB or POBA) (Figure 1).
Conclusions
Post-procedural QFR-gradient within the lesion was an independent and stronger predictor of subsequent TLR, compared with anatomical indexes. Further studies are warranted to investigate whether QFR guidance to optimize PCI procedure could improve clinical outcomes in patients with balloon angioplasty.

Abstract
Abstract
Background and purpose
Fluorine-18-flurodeoxyglucose positron emission tomography (18FDG-PET) is a useful examination assessing active inflammatory myocardium noninvasively in patients with cardiac sarcoidosis (CS). Though immunosuppression like prednisolone (PSL) and Methotrexate (MTX) as alternative therapy is used to suppress the inflammation, little is known about the rate of response and efficacy of MTX for intolerance to PSL therapy.
Methods
From Aug 2016, we prospectively enrolled CS with positively accumulated of FDG in the heart. The initial dose of PSL was 30mg/day, wherefrom the dose was tapered down 5mg/month until 6 months. After 6 months, follow-up 18FDG-PET was performed. Using 18FDG-PET images, we calculated total lesion glycolysis (TLG; SUVmeam x metabolic volume) and calculated the reduction rate of TLG. In order to estimate the response rate to PSL therapy, responder group (R-group) was defined as TLG reduction rate ≥70% and poor-responder group (PR-group) was defined as TLG reduction rate <70% after PSL therapy. After prescribed PSL, subjects with PR-group randomized to PSL (maximum dose 30mg daily and tapered down 5mg/month until 6 months) or to MTX (6mg weekly).
Results
In 64 CS patients, 55 patients had serial 18FDG-PET before and 6 months after PSL therapy. 18FDG-PET images were acquired following 7 day's carbohydrate limitation and after at least 18-h fasting (mean free fatty acid level right before 18FDG-PET acquisition was 1.05 mEq/L). The mean age was 63.4 years old and 42 (76.4%) patients were female. Because of 6 months PSL therapy, even though there were no significant difference in BNP (from 59.9 (26.2–137.6) to 60.4 (18.5–122.0) (P=0.593), LV-Dd (from 50.9 (44.5–59.5) to 49.7 (45.5–61.3) (P=0.666) and LV-EF (from 49.5 (34.4–62.5) to 49.9 (38.0–62.0) (P=0.792) at pre and post therapy, respectively, TLG were detected significant reduction from 216.4 (74.2–411.6) to 0.8 (0.0–8.2), (p<0.001). In response to PSL therapy, 47 (85.5%) CS patients were classified to R-group and 8 (14.5%) were classified to PR-group. Furthermore, when performed block randomization and divide 8 PR-group patients into MTX (n=3) and re-increased PSL (n=5) for more 6 months, MTX group is prone to high rate of TLG reduction than re-increased PSL-group (89.4% vs 59.9%) and one patient belonged to re-increased PSL group showed that the further elevation of TLG level at additional 6-months PSL therapy (349⇒483) (Figure).
Conclusions
1) By immunosuppression therapy using PSL for CS, about 86% patients showed significant reduction of myocardial FDG accumulation. 2) When detected intolerance for PSL therapy, MTX might be effective for reduction of inflammation of sarcoidosis in the heart, which might be effective as an alternate therapy in CS.
