Abstract
OBJECTIVE Previous studies reported mixed results on associations between dietary potassium intake and hyperkalemia in patients with chronic kidney disease (CKD). This study investigated the association between potassium intake from different food sources and hyperkalemia in patients with non-dialysis-dependent CKD. METHODS A total of 285 patients were recruited at a university hospital and two city hospitals in Tokyo. Dietary potassium intake was estimated by a validated diet history questionnaire. Associations of potassium intake from all foods and individual food groups with serum potassium were examined by multivariable linear regression among potassium binder non-users. An association between tertile groups of potassium intake and hyperkalemia, defined as serum potassium ≥5.0 mEq/L, was evaluated by multivariable logistic regression. RESULTS Among 245 potassium binder non-users, total potassium intake was weakly associated with serum potassium (regression coefficient = 0.147, 95% confidence interval (CI): 0.018-0.277), while an association with hyperkalemia was not observed (first vs third tertile: adjusted odds ratio (aOR) = 0.98, 95% CI: 0.29-3.26). As for food groups, potassium intakes from potatoes, pulses, and green/yellow vegetables were positively associated with serum potassium. Patients in the highest tertile of potassium intake from potatoes had higher odds of hyperkalemia as compared to those in the lowest tertile (aOR = 4.12, 95% CI: 1.19-14.34). CONCLUSION Total potassium intake was weakly associated with serum potassium, but not with hyperkalemia. Potassium intake from potatoes was associated with hyperkalemia. These findings highlight the importance of considering food sources of potassium in the management of hyperkalemia in CKD.

Abstract
INTRODUCTION Rheocarna's therapeutic effect is associated with fibrinogen (Fib) and low-density lipoprotein cholesterol (LDL-C) adsorptive removal. This study aimed to retrospectively investigate the association between treatment volume (TV) and circulating blood volume (CBV) and the Fib removal rate (Fib-RR) and LDL-C-RR. METHODS CBV and TV/CBV, cut-off value (CO value), and area under the receiver operating characteristic (ROC) curve (AUC) were calculated. The Fib-RR and LDL-C-RR at the midterm and end of treatment were compared. The groups were further categorized into three groups with TV/CBV lower than or higher than the CO value at the midterm and end (midterm/end; Group L: lower than/lower than CO; Group L/H: lower than/higher than CO; Group H: higher than/higher than CO), and the Fib-RR and LDL-RR of each group at the midterm and end were compared. RESULTS ROC analysis revealed a TV of 1.480 times the BV as CO value, which showed a maximum Youden index predicting a Fib-RR of 20% (AUC: 0.828). Among the three groups, Group L and Group L/H demonstrated significantly higher Fib-RR and LDL-C-RR at the end of the study than in the midterm, while Group H exhibited no difference. CONCLUSION The results reveal that a treatment volume of 1.5 times the circulating blood volume is a sufficient solute removal capacity in the Rheocarna-enabled cases.

Abstract
Coronavirus disease 2019 (COVID-19) affects both life and health. However, the differentiation from other types of pneumonia and effect of kidney disease remains uncertain. This retrospective observational study investigated the risk of in-hospital death and functional decline in ≥ 20% of Barthel Index scores after COVID-19 compared to other forms of pneumonia among Japanese adults, both with and without end-stage kidney disease (ESKD). The study enrolled 123,378 patients aged 18 years and older from a national inpatient administrative claims database in Japan that covers the first three waves of the COVID-19 pandemic in 2020. After a 1:1:1:1 propensity score matching into non-COVID-19/non-dialysis, COVID-19/non-dialysis, non-COVID-19/dialysis, and COVID-19/dialysis groups, 2136 adults were included in the analyses. The multivariable logistic regression analyses revealed greater odds ratios (ORs) of death [5.92 (95% CI 3.62-9.96)] and functional decline [1.93 (95% CI 1.26-2.99)] only in the COVID-19/dialysis group versus the non-COVID-19/non-dialysis group. The COVID-19/dialysis group had a higher risk of death directly due to pneumonia (OR 6.02, 95% CI 3.50-10.8) or death due to other diseases (OR 3.00, 95% CI 1.11-8.48; versus the non-COVID-19/non-dialysis group). COVID-19 displayed a greater impact on physical function than other types of pneumonia particularly in ESKD.

Abstract
INTRODUCTION Chronic kidney disease (CKD) causes a progressive loss of muscle and bone mass, which frequently overlap with and affect clinical outcomes. However, the impact of sarcopenia, low bone mineral density (BMD; osteopenia or osteoporosis), and osteosarcopenia (sarcopenia and low BMD) on CKD progression is yet to be determined. We aimed to address these issues in patients with CKD without kidney replacement therapy (KRT). METHODS This prospective cohort study included 251 outpatients aged ≥65 years with CKD without KRT enrolled in our hospital between June 2016 and March 2017. Sarcopenia was defined according to the 2014 criteria of the Asian Working Group for Sarcopenia (AWGS), and low BMD was defined as a T-score of ≤-1.0. The patients were divided into four groups: normal (no sarcopenia/normal BMD), only low BMD (no sarcopenia/low BMD), only sarcopenia (sarcopenia/normal BMD), and osteosarcopenia (sarcopenia/low BMD). The primary outcome was a composite of all-cause deaths, initiating KRT, and admissions owing to major adverse cardiovascular and cerebrovascular events (MACEs). The secondary outcome was a kidney composite outcome that included a 30 % reduction in creatinine-based estimated glomerular filtration rate (eGFR) and initiating KRT. The outcome risk was determined using the Cox regression models adjusted for potential confounders. RESULTS Median age (25th-75th percentile) and eGFR of the outpatients (35 % women) were 76 (69-81) years and 32.1 (20.8-41.7) ml/min/1.73 m2, respectively. During a median follow-up period of 5.2 years, there were 22 deaths, 117 30 % eGFR reductions, 48 KRTs, and 18 admissions owing to MACEs. The osteosarcopenia group rather than the only low BMD or only sarcopenia groups exhibited a higher risk of the primary (hazard ratio [HR]: 3.28, 95 % confidence interval [CI]: 1.52-7.08) and kidney composite (HR: 2.07, 95 % CI: 1.10-3.89) outcomes. Among the osteosarcopenia-related body compositions and physical functions, low handgrip strength (HGS) was strongly associated with a high risk of primary and kidney composite outcomes (HR: 2.44, 95 % CI: 1.46-4.08; HR: 1.48, 95 % CI: 0.97-2.24, respectively). The increase in HGS but not the body mass index, skeletal muscle mass index, or BMD was associated with lower risks of primary and kidney composite outcomes (HR: 0.93, 95 % CI: 0.89-0.98; HR: 0.96, 95 % CI: 0.92-0.99 per 1 kg, respectively). CONCLUSIONS Osteosarcopenia was associated with poor survival and kidney outcomes in older patients with CKD. Low HGS, which is common in patients with osteosarcopenia and CKD, was associated with increased mortality risk and kidney function decline. These findings can help the risk prediction and pathogenesis of the kidney-bone-muscle axis and improving muscle strength can help mitigate CKD progression.

Abstract
Fibronectin (FN) glomerulopathy (FNG), a rare autosomal hereditary renal disease, is characterized by proteinuria resulting from the massive accumulation of FN in the glomeruli. It typically affects individuals aged 10-50 years. In this report, we describe the case of a 57-year-old man who was diagnosed with FNG through genetic analysis and histological examination that revealed membranoproliferative glomerulonephritis. Despite treatment with prednisolone, the therapeutic response was unsatisfactory. Prednisolone was subsequently tapered and discontinued because the patient had pulmonary thromboembolism. Subsequent comprehensive genetic testing, which was initially not conducted because the patient's parents did not have a history of kidney disease, identified a known disease-causing variant in the FN1 gene, indicating a de novo variant. FNG was further confirmed by positive staining of glomeruli with FN using an IST-4 antibody. Although corticosteroid therapy is commonly employed as the initial treatment for MPGN, its appropriateness depends on the underlying etiology. Thus, clinicians must be aware of potential rare genetic causes underlying MPGN.

Abstract
BACKGROUND Despite increasing incidences of hypertension, recent trends in mortality and urgent dialysis following acute hypertension (AHT) remain undetermined. METHODS This retrospective observational cohort study evaluated 50 316 hospitalized AHT patients from 2010 to 2019, using an administrative claims database in Japan. We examined trends in incidence, urgent dialysis, mortality, and its risk factors using Poisson regression models. Using International Classification of Disease and Related Health Problems, 10th Revision codes, AHT was categorized into 5 spectrums: malignant hypertension (n=1792), hypertensive emergency (n=17 907), hypertensive urgency (n=1562), hypertensive encephalopathy (n=6593), and hypertensive heart failure (HHF; n=22 462). RESULTS The median age of the patients was 76 years, and 54.9% were women. The total AHT incidence was 70 cases per 100 000 admission year. The absolute death rate increased from 1.83% (95% CI, 1.40-2.40) to 2.88% ([95% CI, 2.42-3.41]; Cochran-Armitage trend test, P<0.0001). Upward trends were observed in patients aged ≥80, with lean body mass index ≤18.4, and with HHF. Urgent dialysis rates increased from 1.52% (95% CI, 1.12-2.06) to 2.60% (2.17-3.1; Cochran-Armitage trend test; P=0.0071) in 48 235 patients, excluding maintenance dialysis patients. Older age, men, lean body mass, malignant hypertension, HHF, and underlying chronic kidney disease correlated with higher mortality risk; greater hospital volume correlated with lower mortality risk; and malignant hypertension, HHF, diabetes, chronic kidney disease, and scleroderma correlated with a higher risk of urgent dialysis. CONCLUSIONS Mortality and urgent dialysis rates following AHT have increased. Aging, complex comorbidities, and HHF-type AHT contributed to the rising trend of mortality.

Abstract
INTRODUCTION Chronic limb-threatening ischemia (CLTI) is a clinical syndrome defined by peripheral arterial disease (PAD) combined with rest pain, gangrene, or leg ulceration for longer than two weeks resulting in lower extremity amputation. In recent years, low-density lipoprotein apheresis (LDL-A) has been implemented for PAD treatment. However, it has not been possible to ensure insurance coverage for patients with lower LDL levels than 140 mg/dL under cholesterol-lowering drugs. Rheocarna is a novel adsorption-type blood purification device for the treatment of CLTI by adsorbing LDL and fibrinogen (Fib) that is not constrained by hypercholesterolemia and is not amenable to or nonresponsive to revascularization surgery. The only requirements for use are that the blood flow rate increases up to 200 mL/min gradually. METHODS To evaluate the applicability of this treatment procedure, we compared the removal rates of Fib and LDL following Rheocarna therapy using various blood treatment volumes (6, 10.5, and 19.5 L). RESULTS Fib and LDL removal rates were about 20% and 15%-25% per treatment, with no significant differences between treatment volumes. Following treatment with Rheocarna, blood pressure tends to decrease at first, which later increases, and the higher the treatment volume, the longer the time of low blood pressure tended to be. CONCLUSION Although no significant difference was found in the removal rate of Fib and LDL in response to increase volume to 6 L or beyond in this study, the 6 L volume is considered effective enough for the removal of Fib and LDL.

Abstract
BACKGROUND This multi-institutional, observational study examined whether the outcomes after peritoneal dialysis (PD) catheter placement in Japan meet the audit criteria of the International Society for Peritoneal Dialysis (ISPD) guideline and identified factors affecting technique survival and perioperative complications. METHODS Adult patients who underwent first PD catheter placement for end-stage kidney disease between April 2019 and March 2021 were followed until PD withdrawal, kidney transplantation, transfer to other facilities, death, 1 year after PD start or March 2022, whichever came first. Primary outcomes were time to catheter patency failure and technique failure, and perioperative infectious complications within 30 days of catheter placement. Secondary outcomes were perioperative complications. Appropriate statistical analyses were performed to identify factors associated with the outcomes of interest. RESULTS Of the total 409 patients, 8 who underwent the embedded catheter technique did not have externalised catheters. Of the 401 remaining patients, catheter patency failure occurred in 25 (6.2%). Technical failure at 12 months after PD catheter placement calculated from cumulative incidence function was 15.3%. On Cox proportional hazards model analysis, serum albumin (hazard ratio (HR) 0.44; 95% confidence interval (CI) 0.27-0.70) and straight type catheter (HR 2.14; 95% CI 1.24-3.69) were the independent risk factors for technique failure. On logistic regression analysis, diabetes mellitus was the only independent risk factor for perioperative infectious complications (odds ratio 2.70, 95% CI 1.30-5.58). The occurrence rate of perioperative complications generally met the audit criteria of the ISPD guidelines. CONCLUSION PD catheter placement in Japan was proven to be safe and appropriate.

Abstract
Introduction Chronic kidney disease (CKD) significantly affects activities of daily living (ADLs) before and after the initiation of dialysis, particularly in elderly individuals. However, the impact of admission functional status on dialysis patients' outcome is not fully understood. This study aimed to investigate the effect of the number of ADL disabilities usually measured for all patients hospitalized in Japan on in-hospital outcome for dialysis patients. Methods Using an inpatient administrative claims database, we included 104,557 admissions of patients undergoing chronic dialysis aged 65 years and above from 2012 to 2014. The primary outcome was in-hospital all-cause mortality (evaluated using logistic regression models), and the secondary outcomes were length of stay and care cost. Results The mean age of the participants was 74.0 ± 6.2 years, the mean body mass index (BMI) was 21.8 ± 3.9, 31% needed assistance for one or more of five basic ADLs (feeding, transferring, going to toilet, dressing, and bathing) at admission, and 3.5% (n = 3,701) died after hospitalization. After adjusting for confounding factors, the odds ratios (ORs) (95% confidence intervals) of death for 1, 2, 3, 4, and 5 ADL disabilities were 1.43 (1.19-1.70), 2.04 (1.71-2.45), 2.58 (2.19-3.04), 3.74 (3.35-4.17), and 6.83 (6.29-7.41) versus a complete independence, respectively. The increasing number of ADL disabilities was also associated with greater length of stay and costs. Risk stratification by age, admission functional status, and BMI showed an 18-mortality risk matrix with a maximal risk of a 15.5-higher OR for lean patients aged ≥75 years with severe ADL disability compared with that for patients aged <75 years with middle BMI and no ADL disability on admission. Conclusions Admission functional status decline significantly increases in-hospital mortality, length of stay, and costs. Routine assessment of functional status can facilitate the risk prediction of dialysis patients.

Abstract
Systemic capillary leak syndrome (SCLS), also known as Clarkson's disease, is a rare and potentially lethal condition characterized by hypotension, hemoconcentration, and hypoalbuminemia; however, the cause of SCLS is still uncertain. We present the case of a 62-year-old male with flu-like symptoms who presented to the emergency department with shock. Initial evaluation revealed hemoconcentration, hypoalbuminemia, acute kidney failure, and positive polymerase chain reaction (PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Despite aggressive fluid resuscitation, the shock persisted, and the patient's condition deteriorated. After ruling out ischemia and septic shock, the patient was diagnosed with coronavirus disease 2019 (COVID-19)-associated SCLS. Treatment with remdesivir and intravenous immunoglobulin (IVIG), along with the restoration of intravascular volume, led to the gradual improvement of the patient's condition. The patient experienced pulmonary edema, which was managed by correcting the fluid balance through continuous hemodiafiltration. Eventually, the patient recovered without any residual organ complications. SCLS is often misdiagnosed because of its rarity and non-specific symptoms. Accurate diagnosis and understanding of the disease's pathophysiology are crucial for effective management. This report contributes to the existing literature by presenting a case of COVID-19-associated SCLS and emphasizes the need for further research on its occurrence and outcomes.

Abstract
Avacopan is a novel C5a receptor antagonist recently approved for the treatment of microscopic polyangiitis and granulomatosis with polyangiitis. To our knowledge, thrombocytopenia induced by avacopan has not been reported. We report a case of a 78-year-old man with microscopic polyangiitis who developed rapidly progressive glomerulonephritis (RPGN) and vasculitis neuropathy. After developing RPGN, he was treated with prednisolone, which was ineffective. As the dosage of corticosteroids was decreased, he developed impaired dorsiflexion of the left ankle, tingling and numbness in his feet, consistent with vasculitis neuropathy. After a 3-day administration of methylprednisolone, we started avacopan and prednisolone 20 mg/d to reduce the corticosteroid dosage. One week after starting avacopan, platelet counts began to decrease, eventually leading to the cessation of the drug. The possibility of thrombotic microangiopathy and heparin-induced thrombocytopenia was considered unlikely given the clinical course and laboratory studies. After 3 weeks of avacopan cessation, platelet counts began to increase, suggesting avacopan as the most probable cause of thrombocytopenia. Our case highlights the importance of postmarketing surveillance of avacopan to identify its adverse events that were not reported in clinical trials to ensure its safe use. Clinicians should carefully monitor platelet counts when using avacopan.

Abstract
BACKGROUND As messenger RNA (mRNA)-based vaccines for coronavirus disease 2019 (COVID-19) have been administered to millions of individuals worldwide, cases of de novo and relapsing glomerulonephritis after mRNA COVID-19 vaccination are increasing in the literature. While most previous publications reported glomerulonephritis after the first or second dose of an mRNA vaccine, few reports of glomerulonephritis occurring after the third dose of an mRNA vaccine currently exist. CASE PRESENTATION We report a case of rapidly progressive glomerulonephritis in a patient following the third dose of an mRNA COVID-19 vaccine. A 77-year-old Japanese man with a history of hypertension and atrial fibrillation was referred to our hospital for evaluation of anorexia, pruritus, and lower extremity edema. One year before referral, he received two mRNA vaccines (BNT162b2) for COVID-19. Three months before the visit, he received a third mRNA vaccine (mRNA-1273) for COVID-19. On admission, the patient presented severe renal failure with a serum creatinine level of 16.29 mg/dL, which had increased from 1.67 mg/dL one month earlier, prompting us to initiate hemodialysis. Urinalysis showed nephrotic-range proteinuria and hematuria. Renal biopsy revealed mild mesangial proliferation and expansion, a lobular appearance, and double contours of the glomerular basement membrane. Renal tubules had severe atrophy. Immunofluorescence microscopy showed strong mesangial staining for IgA, IgM, and C3c. Electron microscopy exhibited mesangial and subendothelial electron-dense deposits, leading to a diagnosis of IgA nephropathy with membranoproliferative glomerulonephritis-like changes. The kidney function remained unchanged after steroid therapy. CONCLUSIONS Although the link between renal lesions and mRNA vaccines remains unclear, a robust immune response induced by mRNA vaccines may play a role in the pathogenesis of glomerulonephritis. Further studies of the immunological effects of mRNA vaccines on the kidney are warranted.

Abstract
BACKGROUND Chronic kidney disease (CKD) accelerates vascular calcification via phenotypic switching of vascular smooth muscle cells (VSMCs). We investigated the roles of circulating small extracellular vesicles (sEVs) between the kidneys and VSMCs and uncovered relevant sEV-propagated microRNAs (miRNAs) and their biological signaling pathways. METHODS AND RESULTS We established CKD models in rats and mice by adenine-induced tubulointerstitial fibrosis. Cultures of A10 embryonic rat VSMCs showed increased calcification and transcription of osterix (Sp7), osteocalcin (Bglap), and osteopontin (Spp1) when treated with rat CKD serum. sEVs, but not sEV-depleted serum, accelerated calcification in VSMCs. Intraperitoneal administration of a neutral sphingomyelinase and biogenesis/release inhibitor of sEVs, GW4869 (2.5 mg/kg per 2 days), inhibited thoracic aortic calcification in CKD mice under a high-phosphorus diet. GW4869 induced a nearly full recovery of calcification and transcription of osteogenic marker genes. In CKD, the miRNA transcriptome of sEVs revealed a depletion of 4 miRNAs, miR-16-5p, miR-17~92 cluster-originated miR-17-5p/miR-20a-5p, and miR-106b-5p. Their expression decreased in sEVs from CKD patients as kidney function deteriorated. Transfection of VSMCs with each miRNA-mimic mitigated calcification. In silico analyses revealed VEGFA (vascular endothelial growth factor A) as a convergent target of these miRNAs. We found a 16-fold increase in VEGFA transcription in the thoracic aorta of CKD mice under a high-phosphorus diet, which GW4869 reversed. Inhibition of VEGFA-VEGFR2 signaling with sorafenib, fruquintinib, sunitinib, or VEGFR2-targeted siRNA mitigated calcification in VSMCs. Orally administered fruquintinib (2.5 mg/kg per day) for 4 weeks suppressed the transcription of osteogenic marker genes in the mouse aorta. The area under the curve of miR-16-5p, miR-17-5p, 20a-5p, and miR-106b-5p for the prediction of abdominal aortic calcification was 0.7630, 0.7704, 0.7407, and 0.7704, respectively. CONCLUSIONS The miRNA transcriptomic signature of circulating sEVs uncovered their pathologic role, devoid of the calcification-protective miRNAs that target VEGFA signaling in CKD-driven vascular calcification. These sEV-propagated miRNAs are potential biomarkers and therapeutic targets for vascular calcification.

Abstract
Low-density lipoprotein (LDL) apheresis is effective for nephrotic syndrome in drug-resistant focal segmental glomerulosclerosis (FSGS). Dextran sulfate adsorption of LDL (DSAL) is widely used for this purpose. The Liposorber LA-15 system performs DSAL by membrane plasma separation (mDSAL) using an MA-03 plasma purification device. However, sufficient blood flow (Qb) frequently cannot be obtained from a peripheral vein with mDSAL. The recommended plasma filtration flow rate (Qf) when using the OP-05W membrane plasma separator is no more than 1/3 of Qb, giving plasma removal efficiency (PRE) of about 30%. In contrast, the centrifugal blood component separator Spectra Optia has PRE of 87-92.5% because centrifugal separation enables effective separation of plasma components even at low Qb. Here, we present the case of a man in his 40s with FSGS, for whom we began treatment with mDSAL with the intention of completing a 12-session cycle, but extended treatment times were required due to low Qb. Therefore, we switched to DSAL by centrifugation (cDSAL) using the Liposorber LA-40 system from the 6th session onward. Treatment time decreased from 190 min for the fifth session using mDSAL to 140 min for the sixth session using cDSAL. Mean treatment time also decreased from 155 ± 9 min for mDSAL (5 sessions) to 119 ± 20 min for cDSAL (7 sessions). Moreover, the LDL removal rate at a processed plasma volume was similar for both modalities. In conclusion, cDSAL can enable efficient plasma separation even with low Qb, with a comparable LDL removal rate and shorter treatment time relative to mDSAL.

Abstract
Abstract
Background
Right heart failure following left ventricular assist device (LVAD) implantation is a major complication which significantly impairs functional capacity and quality of life (QoL). Right ventricular (RV) reserve function may limit exercise capacity and QoL in LVAD patients; however, most patients show normal RV haemodynamics at rest.
Purpose
The aim of this study was to investigate whether RV reserve assessed by the changes of RV function during exercise is correlated with exercise capacity and QoL in patients with LVAD.
Methods
We prospectively examined 20 consecutive LVAD patients who were admitted to our university hospital between June 2020 and November 2021 after excluding those who were unable to perform exercise (n=8). All patients underwent invasive exercise right heart catheterisation with simultaneous echocardiography in the supine position. RV stroke work index (RVSWI) was calculated as 0.0136 × stroke volume index × (mean pulmonary artery pressure [mPAP] − right atrial pressure [RAP]) at rest and during exercise. Exercise capacity and QoL were assessed by 6-minute walk distance (6MWD) and peak oxygen consumption (VO2) in cardiopulmonary exercise testing, and the EuroQol visual analogue scale (EQ-VAS), respectively. The patients were divided into two groups according to the median ΔRVSWI (RVSWI change from rest to peak exercise) of 1.45 (interquartile range [IQR] −0.31 to 8.25) g/m2.
Results
Patients were predominantly male (75%) and the median age was 47 (IQR 38–60) years. Patients with lower ΔRVSWI had significantly higher change on RAP (P=0.019), but significantly lower change on mPAP (P<0.001) compared to those with higher ΔRVSWI. There were no significant differences in age, gender, primary aetiology of heart failure, type of LVAD devices, or echocardiographic parameters including tricuspid annular plane systolic excursion, and RVSWI at rest between the groups. ΔRVSWI during exercise were positively correlated with 6MWD (R=0.69, P<0.01) and peak VO2 (R=0.66, P<0.01) (Figure A). In addition, ΔRVSWI during exercise were positively correlated with the EQ-VAS (R=0.48, P=0.031). On the other hand, there was no significant correlation between RVSWI at rest and 6MWD (R=−0.11, P=0.63) and peak VO2 (R=0.13, P=0.95), and the EQ-VAS (R=0.11, P=0.61). During a median follow-up period of 312 (IQR 176–369) days, adverse events occurred in 3 patients (15%), including 1 death and 2 hospitalisations for major bleeding and right heart failure. Kaplan-Meier analysis revealed that the adverse events more frequently occurred in patients with lower ΔRVSWI compared to those with higher ΔRVSWI (Figure B).
Conclusions
ΔRVSWI was positively correlated with 6MWD, peak VO2 and EQ-VAS irrespective of RV function at rest. Our findings suggest that the assessment of RV reserve function using ΔRVSWI would be useful for risk stratification in patients with LVAD.

Background
Epsilon waves on V1-3 leads are specific ECG findings in patients with arrhythmogenic right ventricular (RV) cardiomyopathy (ARVC) suggesting RV conduction delay. Four dimensional (4D) cardiac CT visualizes ARVC characteristics, such as fibro-fatty invasion into RV and left ventricular (LV) myocardium (RVM, LVM), an enlarged RV, reduced RV motion, and bulging.
Purpose
We hypothesize that Epsilon waves in V4-6 leads suggest LV invasion in ARVC. Alternatively, extreme RV enlargement may compress the LV and cause clockwise rotation; an enlarged RV may itself cause epsilon waves in V4-6 leads.
Methods
Retrospective analysis of 17 patients (11 males, 57 ± 17 yrs) with suspected ARVC undergoing cardiac CT and ECG, 9 of whom met 2010 ARVC task force criteria.
Results
All 9 patients had epsilon waves on ECG; 5 had fibro-fatty invasion into the LVM. We divided the 9 into 5 groups by CT: 1) markedly enlarged RV compressing the LV to the left side with fibro-fatty changes exclusively in RVM (N = 1); 2) similar findings in both RVM and LVM (N = 2); 3) moderately enlarged RV without compression of the LV to the left side and fibro-fatty changes exclusively in RVM (N = 3); 4) the same in both RVM and LVM (N = 2); 5) severe mitral valve regurgitation, a markedly enlarged LV, and a fibro-fatty change in both RVM and LVM (N = 1). The patient in group (gp) 1 showed epsilon waves in V1-6 leads, patients in gp 2 had epsilon waves in V1-6 (N = 1), and V3-5 (N = 1) leads; patients in gp 3 had epsilon waves in V1-4 (N = 2), and V1-3 (N = 1) leads, patients in gp 4 had epsilon waves in V1-3 (N = 1), and V1, 2 (N = 1) leads; finally, the patient in gp 5 had epsilon waves in V4-6 leads. Plasma brain natriuretic peptide (BNP) levels were significantly greater in patients in gp 1 & 2 than gp 3 & 4 (1255 ± 838 vs 80 ± 52 pg/ml, P = 0.016).
Conclusions
ARVC patients with a markedly enlarged RV compressing the LV to the left side (gp 1,2) had a broad (V1-6) or different range (V3-5) distribution of epsilon waves and significantly elevated plasma BNP independent of fibro-fatty invasion of the LV, different from typical ARVC (gp 3,4). Additionally, structural change due to complicated heart disease, such as valvular disease (gp5), may also influence the distribution of epsilon waves in ARVC. Abstract Figure.

Background
Medical students find Epsilon and J wave diagnoses by electrocardiogram (ECG) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) difficult.
Purpose
To evaluate the inter observer reliability for detecting Epsilon and J wave in patients with ARVC between medical students and specialists for arrhythmia treatment and seek the problem for the ECG education to the students.
Methods
Nine patients (six males, mean age 59 ± 17 years) meeting 2010 ARVC task-force criteria (Circulation. 2010; 121:1533-1541) underwent a retrospective ECG analysis. First-grade medical students undertook ECG studies for 9 months (4 h/week) by a cardiologist who was not a specialist in arrhythmia treatments according to the Japanese Heart Rhythm Society (JHRS). Medical students detected Epsilon and J waves in all nine ECGs. Two JHRS specialists in arrhythmia treatment independently detected Epsilon and J waves; when diagnoses differed, a final diagnosis was made together.
Results
Epsilon waves were detected in five and eight patients by medical students and specialists, respectively. The distribution of Epsilon waves was determined in inferior and right-side precordial leads by students, but in right-side precordial leads only by specialists (Table). J waves were detected in nine and three patients by medical students and specialists, respectively. The J wave distribution was wider for medical students than specialists.
Conclusions
With ECG findings by specialists as the gold standard, even with a substantial education, medical students tended to diagnose Epsilon waves or notches in QRS as J waves. Lecturers need to equip students with additional basic clinical knowledge, such as Epsilon waves are more frequent in right-side precordial leads in ARVC patients. Abstract Figure. CT and ECG in ARVC

Abstract
Background Physicians have long noted a substantial discrepancy between the reasons for hospital admission and ultimate causes of death, particularly among older adults or patients with complex underlying diseases. However, objective data on this phenomenon are lacking. We aimed to examine the risk of in-hospital death caused by a reason other than the original reason for hospitalization and its association with underlying kidney disease in a nationwide inpatient database. Methods In this retrospective cohort study, we studied 639,556 Japanese adults who died in the hospital from 2012 to 2015, using data from Japan’s Diagnosis Procedure Combination database. We analyzed the discrepancy rate between reasons for hospital admission and death and associated factors using the International Classification of Diseases, 10th Revision (ICD-10) diagnostic codes and seven related categories. Results Among non-chronic kidney disease (CKD) (590,551), CKD (24,708), and end-stage kidney disease (ESKD) (24,297) patients, the median age was 77 years (interquartile range [IQR]: 67–84 years), 83 years (IQR: 75–88), and 75 years (IQR: 67–81), and 25.7%, 30.3%, and 41.6% died from a reason other than the original reason for hospitalization, respectively. Multivariate logistic regression analyses determined CKD/ESKD as the predominant risk factor for this discrepancy, rather than older age, male sex, obesity, and other comorbidities. Sankey diagrams that presented diagnostic changes from hospital admission to death revealed multiple wider segments connecting to different disease classifications, particularly to congestive and septic death in CKD and ESKD patients, respectively. Death owing to another disease classification led to an increase in the median length of hospital stay by 5–7 days and to a 1.3-–1.4-fold increase in medical costs across the populations. Conclusions A substantial proportion of patients with CKD and ESKD died during hospitalization for a reason other than their original reason for admission, leading to increased length of hospital stay and cost.

Abstract
Abstract
Background
The presence and distribution of J waves, the occurrence of ventricular fibrillation (VF), and the presence of left ventricular (LV) myocardial fibrotic or fat change or coronary stenosis may be related.
Purpose
To determine the relationship of frequency and distribution of J waves with presence of myocardial fibrotic or fat change and coronary arterial stenosis on cardiac computed tomography (CT) in survivors of VF.
Methods
We conducted a retrospective analysis of 21 survivors of VF (17 males; mean age, 61±14 years) that were implanted with a cardioverter defibrillator and underwent cardiac CT.
Results
On ECG, four subjects had atrial fibrillation. The mean corrected QT interval was 442±39 msec. On CT, two subjects had significant coronary artery stenosis and 12 had LV myocardial fibrotic and/or fat change. The distribution of J waves were as follows: five subjects had J waves in II, III and aVF leads (three had myocardial fibrotic and/or fat change); and 2 had J waves in III lead (one had myocardial fibrotic and/or fat change). One subject each had J waves in V1 lead; V1, 2 leads; II, III, aVF and V1 leads; II, III, aVF and V1–3 leads; II, III, aVF, aVL and V1–6 leads; II, III, aVF and V1–6 leads; II, III, aVF and V4,5 leads; II, III, aVF and V2–5 leads; and III and aVF leads, respectively. The first two subjects did not have LV myocardial fibrotic and/or fat change and the remaining six subjects had myocardial fibrotic and/or fat change (Figure).
Conclusions
Survivors of VF with organized LV myocardial fibrotic and/or fat change showed more frequent J waves with a wider distribution (reached LV inferior wall leads) than survivors without these changes. Monitoring these characteristics on CT may be useful to predict VF.

Abstract
Plasma volume (PV) variation during therapeutic apheresis (TA) (such as plasma exchange [PE] and selective PE using albumin solution as replacement solution or immunoadsorption plasmapheresis) has been considered to be unignorable. It changes the concentration of the target molecule and might impact its removal rate (RR.) This study aimed to evaluate the effects of PV variation on the calculation of the RR of fibrinogen and immunoglobulin by categorizing the hematocrit (Ht) change during TA into two patterns, that is, increased group and decreased group. In all modalities of TA, the Ht level frequently changed during apheresis sessions. In calculating RR, RR calculated with Ht adjustment was significantly higher than that calculated without adjustment in the increased group and significantly lower than it in the decreased group. Therefore, RR might have been underestimated in the increased group and overestimated in the decreased group when RR was calculated without Ht adjustment. Ht adjustment is suggested to be crucial in calculating RR in TA.

Abstract
We herein report a case of severe coronavirus disease 2019 (COVID-19) in which high-dose intravenous immunoglobulin (IVIg) treatment achieved significant clinical improvement of deterioration of pulmonary inflammation after temporary clinical improvement. In the present case, clinical and radiological deterioration occurred despite a decrease in viral load, suggesting that deterioration was caused by reactivation of proinflammatory factors, such as tumor necrosis factor-α and interleukin-6, rather than direct viral effects. IVIg treatment may provide not only immunosuppressive effects but also inhibition of proinflammatory cytokines, indicating that treatment including IVIg may be effective by inhibiting cytokine storm in severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection.

Abstract
Background Chronic kidney disease (CKD) involves many factors that can cause frailty and oral hypofunction. We aimed to investigate the prevalence of frailty and oral hypofunction and to examine the associations among kidney function, frailty, and oral function in adults with CKD in Japan. Methods This cross-sectional study was conducted at two institutions. The participants included 109 patients with CKD stages 3–5 who visited outpatient clinics or were admitted for inpatient treatment. Frailty was evaluated using the Japanese version of the Cardiovascular Health Study frailty criteria. Oral function was evaluated by assessing oral motor skills [oral diadochokinesis (ODK) rate], masticatory ability, and the repetitive saliva swallowing test. The estimated glomerular filtration rate (eGFR) was used to indicate kidney function. We examined the associations among kidney function, frailty, and oral function using binomial logistic regression analysis. Results In total, 31 participants (28.4%) were classified as being frail. Univariate analysis showed that age, body mass index, eGFR, and haemoglobin level were significantly associated with frailty. ODK and swallowing function were significantly associated with frailty. Multivariate analysis revealed that frailty was significantly associated with eGFR [odds ratio (OR) 0.96, 95% confidence interval (CI) 0.92–1.00, p = 0.048] and ODK rate (OR 0.68, CI 0.47–0.98, p = 0.038). However, no significant association was found between CKD severity and masticatory or swallowing function. Conclusion We found a high prevalence of frailty in patients with CKD and a significant association between frailty and oral motor skills, affecting the swallowing function of patients with nondialysis CKD. The high prevalence of frailty among patients with CKD suggests that routine assessment of frailty is necessary to prevent the development of severe complications. In addition, oral and kidney function should be carefully evaluated, and oral health education and interventions should be performed for patients with CKD.

Abstract
OBJECTIVES To evaluate the renal function after adrenalectomy in patients with Cushing's syndrome in comparison with that in patients with primary aldosteronism. METHODS This retrospective study included 35 patients with Cushing's syndrome and 51 patients with primary aldosteronism who underwent unilateral adrenalectomy and were followed up for >6 months. The renal function was analyzed before and after adrenalectomy using the estimated glomerular filtration rate. Postoperative renal impairment was defined as a >25% reduction in the estimated glomerular filtration rate from baseline at 1 month after adrenalectomy. Multivariate logistic regression analyses were carried out to examine whether the differences between Cushing's syndrome and primary aldosteronism increased the risk of postoperative renal impairment. Longitudinal changes were calculated starting 1 month after adrenalectomy using the linear mixed model. RESULTS The mean estimated glomerular filtration rate in both groups significantly decreased at 1 month after adrenalectomy from baseline. Postoperative renal impairment was observed in four (11%) and 12 (24%) patients in the Cushing's syndrome and primary aldosteronism groups, respectively. Multivariate analysis showed that preoperative systolic blood pressure was independently associated with postoperative renal impairment, but not with the type of the disease. There was no significant increase or decrease in postoperative estimated glomerular filtration rate observed after the initial decrease after adrenalectomy in either group. CONCLUSIONS Patients with Cushing's syndrome show the same persistent renal impairment after adrenalectomy as that reported in patients with primary aldosteronism. Attention should be given to possible masked renal damage in clinical practice for the management of Cushing's syndrome.

Abstract
BACKGROUNDS End-stage kidney disease (ESKD) is associated with increased risk of fracture and subsequent morbidity and mortality. However, fracture site-specific mortality in ESKD patients have yet to be elucidated in comparison with the general population. METHODS In this population-based cohort derived from the Diagnosis Procedure Combination database of Japan from 2012 to 2014, we included 9320 ESKD patients undergoing hemodialysis and 547,726 patients without ESKD who were hospitalized for five major fractures, including hip (proximal femur), spine, forearm, upper arm, and leg (distal femur and proximal tibia). Overall and site-specific risks of in-hospital death were determined by logistic regression models. RESULTS The age- and sex-adjusted mortality rates were 4.91% (95% confidence interval [CI], 4.46-5.37) and 1.02% (95% CI, 0.99-1.06) in the hemodialysis and general population groups, respectively. The multivariate odds ratio (OR) of death in hemodialysis patients versus the general population was 2.48 (95% CI, 2.25-2.74) for overall fractures, and was particularly high for a subgroup of upper arm fracture (OR 4.82, 95% CI, 3.19-7.28). The site-specific odds of death (95% CI) among hip, spine, forearm, upper arm, and leg (reference) fractures were 1.77 (0.98-3.18), 1.48 (0.79-2.75), 0.19 (0.04-0.86), and 2.01 (1.01-4.01) in hemodialysis patients, and 1.28 (1.13-1.45), 1.00 (0.88-1.14), 0.13 (0.10-0.17), and 0.83 (0.70-0.97) in the general population, respectively. CONCLUSION Hemodialysis patients experienced a 4.8-fold higher mortality rate after fractures than the general population. Mortality after upper arm fracture was specifically high in patients on hemodialysis, likely due to the involvement of vascular access located on the fractured arm.

Abstract
Abstract
Purpose and method
Japanese Heart Rhythm Society requested electrophysiology centers to register the data of patients who underwent catheter ablation for atrial fibrillation (AF) in designated eight months from 2011 to 2017. We assessed the incidence and predictors of pericardial effusion (PE) as an early complication of AF ablation.
Results
More than two hundred EP centers reported the data of 13,233 AF ablation cases (age; 64.2±10.7 years, male; 72.6%, paroxysmal AF; 63.4%). Clinically significant complications occurred in 601 subjects (4.5%). Critical PE occurred in 116 patients (0.8%), while six of them required open-chest surgery. Overall complication rate did not show significant changes. In contrast, incidence of PE declined over time (2012:1.2%, 2017:0.5%, p=0.003). Multiple logistic regression analysis showed that seven factors were related with higher incidence of PE. Among these factors, primary extra-PV ablation and hypertrophic cardiomyopathy (HCM) were more remarkably associated with higher rate of PE (PVI[−] vs. PVI[+]= 9.0% vs. 0.8%, OR 12.3, p<0.001; HCM: [+] vs. [−] = 2.6% vs. 0.8%, OR 3.26, p=0.001). Comorbidity of coronary artery disease (CAD) and use of CARTO system were related with lower PE rate (CAD: [+] vs [−] = 0.2% vs. 0.9%, OR 0.22 [p=0.034], CARTO: [+] vs [−] = 0.7% vs. 1.2%, OR 0.52 [p=0.001]). None of cryobaloon ablation, gender, type of AF, center volume, periprocedural oral anticoagulant, or left atrial diameter was significantly related with the occurrence of PE.
Conclusions
Incidence of critical PE decreased recently. HCM and primary extra-PV ablation were outstanding predictors of critical PE.

Abstract
Encephalopathy is a rare side effect of cephalosporin treatment. We herein present a case of encephalopathy induced by ceftriaxone, a third-generation cephalosporin, in a patient with renal failure. An 86-year-old woman on maintenance hemodialysis received ceftriaxone for Helicobacter cinaedi bacteremia. Her mental status deteriorated during antibiotic treatment, and an electroencephalogram revealed triphasic waves predominantly in the frontal area. Her consciousness improved after the discontinuation of the antibiotic due to the suspicion of ceftriaxone-induced encephalopathy. This is the first reported case of encephalopathy associated with high plasma and cerebrospinal fluid ceftriaxone concentrations, and provides significant evidence for a causal relationship between the administration of ceftriaxone and the onset of encephalopathy.

Abstract
Autoimmune neurological diseases are often treated by immunoadsorption using a conventional plasma separator and tryptophan-immobilized column (IA). However, there is only one case report on treatment with immunoadsorption using a selective plasma separator and tryptophan-immobilized column (SeIA) in clinical practice. This study aimed to investigate the removal characteristics of antibodies against acetylcholine receptors (AChRAb), immunoglobulin G, fibrinogen, and factor XIII (FXIII) in IA and SeIA in four patients with myasthenia gravis. A total of 19 sessions of immunoadsorption were performed (five sessions of IA and 14 sessions of SeIA) when the processed plasma volume was 2 L. The corresponding reductions were 52.5% ± 6.2% for AChRAb, 58.8% ± 4.2% for fibrinogen, and 36.9% ± 5.5% for FXIII after one session of IA. The corresponding reductions were 45.2% ± 9.9% for AChRAb, 3.5% ± 6.9% for fibrinogen, and -4.6% ± 11.1% for FXIII after one session of SeIA. The removal rates for AChRAb, fibrinogen, and FXIII in IA were significantly higher than those in SeIA. IA could effectively remove AChRAb, and SeIA could retain fibrinogen and FXIII. IA can be combined with SeIA, resulting in both IgG autoantibodies removal by IA and retention of coagulation factors by SeIA.

Abstract
Patients with an indwelling tunneled dialysis catheter (TDC) for hemodialysis access are at a high risk of developing methicillin-resistant Staphylococcus aureus (MRSA) infection. MRSA bacteremia complications rarely include infected aneurysm. Here, we report the first case of an infected thoracic aneurysm associated with TDC-related MRSA bacteremia. An 86-year-old Japanese male with a TDC for hemodialysis access developed TDC-related MRSA bacteremia. Intravenous vancomycin was initiated, and the TDC was removed on day 3. Despite removal of the catheter and initiation of vancomycin treatment, MRSA bacteremia persisted. Chest computed tomography (CT) showed no aneurysm; however, calcification of the thoracic aorta was detected on admission. The patient subsequently developed hemosputum. CT revealed a thoracic aneurysm, which turned out to be caused by MRSA bacteremia. The patient eventually died because of the rupture of the infected aneurysm, as confirmed by autopsy. This report demonstrates TDC management in a patient with TDC-related MRSA bacteremia and the importance of investigating a metastatic infection to a calcified artery if bacteremia persists.
