Abstract
UNLABELLED Our human observational study showed that elevated arginine vasopressin levels by heavy exercise, not catecholamines, were associated with elevated serum tartrate-resistant acid phosphatase 5b (TRACP-5b). The increase in serum calcium was positively associated with percent changes of TRACP-5b, implying the involvement of bone resorption in the pathogenesis of exercise-induced hypercalcemia. INTRODUCTION It remains unclear whether enhanced bone resorption explains exercise-induced hypercalcemia. An experimental study demonstrated that arginine vasopressin (AVP) stimulated osteoclast activity. METHODS We conducted a prospective observational study, enrolling 65 trained healthy male officers of the Japan Self-Defense Forces (34 and 31 in waves 1 and 2, respectively). Before and after a 5-h heavy exercise, we collected laboratory data including bone markers, symptoms, and ionized calcium (iCa; wave 2 only). As blood calcium levels change after exercise, we estimated calcium (corrected calcium) levels immediately after the exercise using the correlation between blood calcium and time from the end of exercise in another cohort. RESULTS Body weight decreased by 6.9% after the exercise. Corrected post-exercise serum total calcium (tCa) and iCa levels were significantly higher than pre-exercise levels, and 18% of participants showed hypercalcemia defined as corrected tCa >10.4 mg/dL or iCa >1.30 mmol/L. Serum tartrate-resistant acid phosphatase 5b (TRACP-5b), plasma three fractions of catecholamines, and AVP elevated significantly (median 14.3 pg/mL), while procollagen type 1 N-terminal propeptide and whole parathyroid hormone showed significant decreases. Corrected tCa increase showed a non-linear positive association with percent changes of TRACP-5b (%ΔTRACP-5b) even after adjustment for confounders. In addition, %ΔTRACP-5b was not associated with catecholamines, but with post-exercise AVP levels after adjustment for pre-exercise TRACP-5b. Symptoms of nausea or vomiting (observed in 20%) were positively associated with corrected post-exercise iCa after adjustment for post-exercise blood pH. CONCLUSION AVP elevation may explain bone resorption and the following hypercalcemia in the setting of heavy exercise.

Abstract
Recently, automatic feeders have become popular for collecting daily feed intake data in the pig industry, making it possible to evaluate genetic effects on feed efficiency and resilience traits, expressed as day-to-day fluctuations in feeding records. This study aimed to understand the influence of genetic factors on feed efficiency traits, including residual intake and BW gain (RIG), and resilience traits, as well as to compare the differences in genetic parameter estimates among three purebred pig breeds. A total of 6 103 pigs from three breeds (Large White: 1 193 pigs, Landrace: 3 010 pigs, and Duroc: 1 900 pigs) were raised in a specific pathogen-free environment. The growth and feed intake records during the testing period were obtained using automatic feeders, and the average daily gain (ADG) and average feed intake (AFI) were calculated. Feed conversion ratio (FCR), residual feed intake (RFI), residual gain, and RIG were calculated as feed efficiency traits, and the log-transformed variance of deviation for the daily feed intake (LnVar_FI), daily occupation time (LnVar_OC), and the daily number of visits to the feeder (LnVar_VT) was calculated as resilience traits. After estimating the genetic parameters for each breed, a meta-analysis was performed to obtain the weighted mean of heritability estimates (hm2) and genetic correlation estimates (GCm) for the three breeds. The hm2 were moderate and ranged from 0.31 to 0.39 for feed efficiency traits and 0.31 to 0.40 for resilience traits, and there were no significant differences in heritability estimates among the three breeds except for AFI, RFI, and RIG. For feed efficiency traits, the FCR and RIG showed favourably moderate GCm with AFI (0.29 and -0.33, respectively) and ADG (-0.39 and 0.31, respectively). For resilience traits, the LnVar_FI and LnVar_VT showed favourably low to moderate GCm with FCR (0.33 and 0.28, respectively) and RIG (-0.37 and 0.28, respectively), and there were no genetic relationships of LnVar_OC with FCR and RIG (the absolute value of GCm was 0.01). There was no significant difference in the genetic correlation estimates among the three breeds for feed efficiency and resilience traits. Our results suggest that feed efficiency and resilience traits were heritable, and resilience traits showed favourable or no genetic correlation with feed efficiency traits. In addition, the influence of genetic factors on feed efficiency and resilience traits could be the same among breeds.

Abstract
Sarcoidosis is a multisystem granulomatous disease of unknown cause. With cardiac sarcoidosis (CS), patients represent a wide range of cardiac manifestations from subtle to overt morphological and functional abnormalities. The advent of ultrasound technologies has enabled to identify not only typical findings to CS such as basal thinning of the ventricular septum, but also subclinical myocardial alterations. Based on our recent experiences, we currently introduce a variety of myocardial manifestations evaluated by echocardiography on seven CS patients being selected. Most of the patients exhibited typical cardiac involvement and the remaining fairly unusual.

Abstract
In order to improve the quality of life of dialysis patients, our group have been developing an implantable hemofiltration device (IHFD) composed of multiple layers of dialysis membranes and microfluidic channels. To improve the hemodialysis performance of IHFD, preventing the negative filtration, which is caused by the oncotic pressure of blood, is mandatory. In this study, we fabricated IHFDs with five different microchannel designs and experimentally investigated the performance of each device in in vitro experiment. In addition, the successful IHFD was further evaluated by ex vivo experiments with a beagle dog. The experiments verified the effectiveness of the microchannel design, which will be used for the IHFD for in vivo experiments with pigs in the future.

Abstract
BACKGROUND The left atrial appendage (LAA) has considerable variations in its size, shape, and spatial relationship with other cardiac structures. Absence of the LAA is a congenital cardiac condition usually identified by an imaging modality intended for other purposes. Absence of the LAA has been described in a total of 19 case reports so far; however, no cases of "hypoplastic" LAA in a real sense have ever been reported. CASE REPORT We herein report a case of hypoplastic, but not truly absent, LAA in a 76-year-old man scheduled for catheter ablation against atrial flutter. Preprocedural transesophageal echocardiography (TEE) performed in this patient to exclude intracardiac thrombosis failed to detect the LAA, although Doppler color-flow mapping revealed a jet signal spewed out into the main LA around where the LAA would be located. The LAA was also not detectable by routinely developed tomographic images from computed tomography (CT) angiography. Eventually, however, the multiplanar reconstruction into 3-dimensional volume rendering via the CT angiography identified a very small LAA. Those findings by TEE and CT led to a diagnosis of hypoplastic LAA. CONCLUSIONS Hypoplastic LAA should be kept in mind when considering LAA interventions as well as anticoagulation treatment. Multiple imaging modalities are necessary to recognize morphological aberration of the LAA.

Abstract
Abstract
Background
A lack of adherence and inadequate self-care behaviours are common reasons for recurrent hospitalizations among patients with heart failure (HF). Although patients recognize the importance of HF self-care, it is sometimes difficult to correct their behavioural patterns. Motivational interviewing is a communication technique to resolve ambivalence towards changing behaviour, and it has been widely used to promote behavioural changes and improve outcomes in various chronic diseases. We described a case of advanced HF with reduced ejection fraction in which motivational interviewing lead to stabilize the patient’s condition.
Case summary
A 33-year-old man was diagnosed with dilated cardiomyopathy who experienced repeated episodes of HF requiring hospitalization despite optimal guideline-based HF treatment. Transthoracic echocardiography disclosed a severely reduced left ventricular (LV) contraction (LV ejection fraction 18%) and cardiopulmonary exercise testing disclosed markedly reduced functional capacity and increased ventilatory response (peak VO2 of 10.7 mL/min/kg, predicted peak VO2 of 34.7% and VE/VCO2 slope of 35.2). In this case, poor adherence to self-care such as excessive fluid intake and excessive daily activities after hospital discharge was the main cause of recurrent hospitalization for HF. Despite repeated patient education to correct his diet and lifestyle, he could not change his lifestyle behaviour. However, motivational interviewing dramatically helped stabilize the patient’s condition and prevent HF re-hospitalization.
Discussion
In general, patients with advanced HF and reduced ejection fraction despite optimal medical therapy should be evaluated to assess their eligibility of cardiac transplantation or palliative care. Motivational interviewing might represent a new therapeutic approach for stabilizing and preventing HF through self-care behavioural changes, even in patients with advanced HF and severely reduced ejection fraction.

Abstract
Background Hepatectomy with vascular resection (VR) for perihilar cholangiocarcinoma (PHCC) is a challenging procedure. However, only a few reports on this procedure have been published and its clinical significance has not been fully evaluated. Methods Patients undergoing surgical resection for PHCC from 2002–2017 were studied. The surgical outcomes of VR and non-VR groups were compared. Results Some 238 patients were included. VR was performed in 85 patients. The resected vessels were hepatic artery alone (31 patients), portal vein alone (37 patients) or both (17 patients). The morbidity rates were almost the same in the VR (49.4 per cent) and non-VR (43.8 per cent) groups (P = 0.404). The mortality rates of VR (3.5 per cent) and non-VR (3.3 per cent) were also comparable (P > 0.999). The median survival time (MST) was 45 months in the non-VR group and 36 months in VR group (P = 0.124). Among patients in whom tumour involvement was suspected on preoperative imaging and whose carbohydrate antigen 19-9 (CA19-9) value was 37 U/ml or less, MST in the VR group was significantly longer than that in the non-VR group (50 versus 34 months, P = 0.017). In contrast, when the CA19-9 value was greater than 37 U/ml, MST of the VR and non-VR groups was comparable (28 versus 29 months, P = 0.520). Conclusion Hepatectomy with VR for PHCC can be performed in a highly specialized hepatobiliary centre with equivalent short- and long-term outcomes to hepatectomy without VR.

Abstract
Background Mogamulizumab was compared with vorinostat in the phase 3 MAVORIC trial (NCT01728805) in 372 patients with relapsed/refractory mycosis fungoides (MF) or Sézary syndrome (SS) who had failed ≥1 prior systemic therapy. Mogamulizumab significantly prolonged progression‐free survival (PFS), with a superior objective response rate (ORR) vs. vorinostat. Objectives This post hoc analysis was performed to evaluate the effect of baseline blood tumour burden on patient response to mogamulizumab. Methods PFS, ORR, time to next treatment (TTNT), skin response (modified Severity‐Weighted Assessment Tool [mSWAT]) and safety were assessed in patients stratified by blood classification (B0 [n = 126], B1 [n = 62], or B2 [n = 184], indicating increasing blood involvement). Results Investigator‐assessed PFS was longer for mogamulizumab versus vorinostat across all blood classes, significantly so for B1 and B2 patients. ORR was higher with mogamulizumab than with vorinostat in all blood classification groups and more markedly so with escalating B class (B0: 15.6% vs. 6.5%, P = 0.0549; B1: 25.8% vs. 6.5%, P = 0.2758; B2: 37.4% vs. 3.2%, P < 0.0001). TTNT was significantly longer for patients treated with mogamulizumab versus vorinostat with B1 (12.63 vs. 3.07 months; HR 0.32 [95% CI 0.16–0.67]; P = 0.0018) and B2 (13.07 vs. 3.53 months; HR 0.30 [95% CI 0.21–0.43]; P < 0.0001) blood involvement. In the mogamulizumab arm, 81 patients (43.5%) had ≥50% change in the mSWAT vs. 41 patients (22.0%) with vorinostat; mSWAT improvements with mogamulizumab occurred most often in B1 and B2 patients. Rapid, sustained reductions were seen in CD4+CD26‐ cell counts and CD4:CD8 ratios in mogamulizumab patients for all B classes. Treatment‐emergent adverse events were less frequent overall with mogamulizumab and similar in frequency regardless of B class. Conclusions This post hoc analysis indicates greater clinical benefit with mogamulizumab vs. vorinostat in patients with MF and SS classified as having B1 and B2 blood involvement.

Abstract
Pesticides to protect crops from pests are subject to rigorous risk assessment before registration in Japan. However, further information needs to be collected regarding the assessment of impacts on the natural environment. In particular, nitrifying bacteria play a role in converting ammonium salts to nitrates in soil. However, there is limited research covering the effects of insecticides on nitrification, despite several fungicides and herbicides have an inhibitory effect on nitrifying bacteria. Therefore, we investigated the effect of pesticides on the nitrification when applied to soil. The application of both pesticides promoted ammonia oxidation, and suppressed nitrite oxidation in a high-concentration treatment of dinotefuran. In addition, it was clarified that the diversity and species richness of soil bacteria was significantly reduced when the pesticides were applied to the soil, and that the specific soil bacteria (Metyhlotenera spp.) dominated the application of the pesticides.

Abstract
Background:Coronary periarteritis is one of the clinical manifestations of IgG4-related disease. It can cause serious conditions such as angina and ruptured aneurysms. Therefore, it is important to recognize the clinical and radiological characteristics, which was little known.Objectives:We report four patients with IgG4-related coronary periarteritis with a systematic literature review.Methods:We identified four patients with IgG4-related coronary periarteritis at the St. Luke’s International Hospital in Tokyo, Japan from 2014 to 2020. A systematic literature review was conducted for English articles on IgG4-related coronary periarteritis cases with a full text or abstract available. We summarized patient demographics, IgG and IgG4 titers, the site and morphological type of coronary lesion, and other organ involvements.Results:Our 4 cases and 38 cases identified by the literature review were assessed. Coronary artery lesions were detected by a coronary CT in all but two cases. Wall thickening was the most common type of the lesion. Moreover, there were 32 (76.1%) patients with other organ involvements. The commonest other lesion was peri-aortitis in 21 (50.0%) patients. In cases with peri-aortitis, IgG and IgG4 titers were significantly higher than those without peri-aortitis (IgG4; 1540 [705.0, 2570.0] vs 246.0 [160.0, 536.3]; p = 0.001, IgG; 3596.5 [2838.3, 4260.0] vs 1779.0 [1288.3, 1992.8]; p =0.040). In addition, 15 (71.4%) patients of them had three or more IgG4 related organ involvements.Conclusion:Coronary CT was a useful imaging modality for the diagnosis of IgG4-related coronary periarteritis, and wall thickening was the most common lesion. Moreover, about half cases coexisted with peri-aortitis. Peri-aortitis and other organ involvements should be screened in those with higher IgG and IgG4.Table 1.Characteristics of our cases and the literature review cases.RCA: right coronary artery, LAD: left anterior descending artery, LCx: left circumflex arteryDisclosure of Interests:None declared

Abstract
The spleen is associated with inflammation, and the size of the spleen is affected by hemodynamic congestion and sympathetic stimulation. However, the association between splenic size and prognosis in patients with heart failure remains unknown. Between January 2015 and March 2017, we analyzed 125 patients with acute decompensated heart failure who were assessed by computed tomography (CT) on the day of admission. The spleen was measured by 3-dimensional CT and then the patients were assigned to groups according to their median splenic volume indexes (SpVi; splenic volume/body surface area). We then compared their baseline characteristics and rates of readmission for heart failure after one year. The median SpVi was 63.7 (interquartile range: 44.7-95.3) cm3/m2. Age did not significantly differ between the groups. Patients with a high SpVi had more significantly enlarged left atria and left ventricles. Multiple regression analysis identified significant positive correlations between SpVi and posterior wall thickness as well as left ventricular mass index. Kaplan-Meier analysis revealed lower event-free rates in the patients with a high, than a low SpVi (P = 0.041, log-rank test). After adjustment for potential cofounding factors, SpVi was independently associated with readmission for heart failure (Hazard ratio, 2.25; 95% confidence interval, 1.01-5.02; P = 0.047). In conclusion, increased splenic volume is independently associated with readmission for heart failure among patients with acute decompensated heart failure.

Abstract
BACKGROUND Hepatectomy with extrahepatic bile duct resection is associated with a high risk of posthepatectomy liver failure (PHLF). However, the utility of the remnant liver volume (RLV) in cholangiocarcinoma has not been studied intensively. METHODS Patients who underwent major hepatectomy with extrahepatic bile duct resection between 2002 and 2018 were reviewed. The RLV was divided by body surface area (BSA) to normalize individual physical differences. Risk factors for clinically relevant PHLF were evaluated with special reference to the RLV/BSA. RESULTS A total of 289 patients were included. The optimal cut-off value for RLV/BSA was determined to be 300 ml/m2. Thirty-two patients (11.1 per cent) developed PHLF. PHLF was more frequent in patients with an RLV/BSA below 300 ml/m2 than in those with a value of 300 ml/m2 or greater: 19 of 87 (22 per cent) versus 13 of 202 (6.4 per cent) (P < 0.001). In multivariable analysis, RLV/BSA below 300 ml/m2 (P = 0.013), future liver remnant plasma clearance rate of indocyanine green less than 0.075 (P = 0.031), and serum albumin level below 3.5 g/dl (P = 0.015) were identified as independent risk factors for PHLF. Based on these risk factors, patients were classified into three subgroups with low (no factors), moderate (1-2 factors), and high (3 factors) risk of PHLF, with PHLF rates of 1.8, 14.8 and 63 per cent respectively (P < 0.001). CONCLUSION An RLV/BSA of 300 ml/m2 is a simple predictor of PHLF in patients undergoing hepatectomy with extrahepatic bile duct resection.
