Abstract
INTRODUCTION Diabetes mellitus (DM) is known to be a cause of cervical internal carotid artery stenosis (ICS). In this study, we investigated the natural history of asymptomatic ICS in DM patients without surgical intervention. METHODS We conducted a retrospective study of 148 DM patients with asymptomatic ICS treated medically at the Kansai Electric Power Hospital from April 2013 to March 2023, inclusive. We examined the incidence of ischemic stroke with ICS and evaluated the patients' clinical characteristics and imaging findings. RESULTS Ischemic stroke with ICS occurred in 7 patients (4.7 %), and only smoking history was significantly correlated with the incidence of ischemic stroke (p = 0.04). DISCUSSION The incidence rate of ischemic stroke with ICS in this study (4.7%) was comparable to the previous report. The result that, the correlated factors of the incidence of ischemic stroke in DM patients with ICS was only smoking history, seemed acceptable. However, prospective studies with a larger number of cases may be needed in the future to determine the correlated factors more eligibly.

Abstract
Intestinal adaptation does not necessarily recover absorptive capacity in short bowel syndrome (SBS), sometimes resulting in intestinal failure-associated liver disease (IFALD). Additionally, its therapeutic options remain limited. Polyamines (spermidine and spermine) are known as one of the autophagy inducers and play important roles in promoting the weaning process; however, their impact on intestinal adaptation is unknown. The aim of this study was to investigate the impact of polyamines ingestion on adaptation and hepatic lipid metabolism in SBS. We performed resection of two-thirds of the small intestine in male Lewis rats as an SBS model. They were allocated into three groups and fed different polyamine content diets (0%, 0.01%, 0.1%) for 30 days. Polyamines were confirmed to distribute to remnant intestine, whole blood, and liver. Villous height and number of Ki-67-positive cells in the crypt area increased with the high polyamine diet. Polyamines increased secretory IgA and mucin content in feces, and enhanced tissue Claudin-3 expression. In contrast, polyamines augmented albumin synthesis, mitochondrial DNA copy number, and ATP storage in the liver. Moreover, polyamines promoted autophagy flux and activated AMP-activated protein kinase with suppression of lipogenic gene expression. Polyamines ingestion may provide a new therapeutic option for SBS with IFALD.

Abstract
BACKGROUND Twig-like middle cerebral artery (T-MCA) is reported as a rare vascular anomaly characterized by reconstitution of the M1 segment of the middle cerebral artery (MCA) by a plexiform network of small vessels. Although it is generally believed that the etiology of T-MCA is an embryological persistence, some investigators have suggested that T-MCA may be a secondary consequence. Here, the authors report a second case of de novo T-MCA formation and reconsider the concept of T-MCA in connection with isolated MCA disease. OBSERVATIONS A 40-year-old man's brain magnetic resonance imaging (MRI) checkup showed moderate stenosis of the M1 segment of the left MCA. Annual MRI follow-up was planned, and when performed 1 year later, it showed occlusion of the M1 segment of the left MCA. Cerebral angiography revealed occlusion of that M1 segment with abnormal arterial networks. This case was diagnosed as de novo T-MCA. The patient has remained asymptomatic for 2 years. LESSONS The reports of de novo T-MCA indicate that acquired factors may be involved in the pathogenesis of T-MCA. We suggest that T-MCA should be defined as a variety of isolated MCA disease with new vessel formation.

Abstract
BACKGROUND The management and fate of liver transplant (LT) recipients with preformed donor-specific antibodies (pDSA) remain controversial. The aim of this study was to evaluate the clinical impact of rituximab desensitization on pDSA in LT recipients. MATERIAL AND METHODS This retrospective observational study enrolled 120 LT patients aged ≥18 years. Patients with pDSA were administered 500 mg/body rituximab 1-21 days before LT, except for those who had an active infection or had insufficient time to receive rituximab. We allocated patients to groups with or without pDSA, and then divided patients with pDSA into rituximab (+) and rituximab (-) groups for further analysis. RESULTS Twenty-three patients (19.2%) with pDSA were identified. Of these, 18 received rituximab and 5 did not receive rituximab. No patients developed adverse events related to rituximab. In both groups, the levels of pDSA class I in all patients were decreased immediately after LT, whereas those of pDSA class II decreased slowly. There were no significant differences in pathology findings and overall survival between patients with pDSA who were rituximab (+) or rituximab (-), and between patients with or without pDSA. CONCLUSIONS Rituximab desensitization for LT patients with pDSA was managed successfully without significant complications. Due to the small sample size, we could not demonstrate the benefit of rituximab desensitization for LT patients compared with the rituximab (-) group. Additionally, clinical outcomes in patients with pDSA, with or without rituximab, were similar to those without pDSA. Rituximab desensitization might be not essential for LT.

Abstract
Tyrosine kinase inhibitors (TKIs) have been widely used to treat chronic myeloid leukemia. Nilotinib and ponatinib, which are second- and third-generation TKIs, have been reported to cause cerebrovascular arterial complications. Here, we present two cases of moyamoya disease presenting with symptomatic ischemic stroke during new-generation TKI treatment. We judged that new-generation TKI treatment was a factor in symptomatic ischemic stroke of unknown moyamoya disease in both cases. Noninvasive examinations using magnetic resonance imaging or carotid ultrasonography should be performed before and during new-generation TKI treatment in order to prevent symptomatic ischemic stroke.

Abstract
RATIONALE The purpose of this case report is to describe a case of successful early rehabilitation intervention for simultaneous liver and kidney transplantation (SLKT). PATIENT CONCERNS A 51-year-old Japanese man was diagnosed with Caroli disease 27 years ago. Hemodialysis was introduced due to end-stage renal disease 17 years ago. DIAGNOSES After successful SLKT, the patient was extubated on postoperative day (POD) 1, liberated from dialysis on POD 4, and discharged from the intensive care unit on POD 9. INTERVENTIONS Supervised rehabilitation was started on POD 2, and the patient was able to walk 100 m on POD 9. Electrical muscle stimulation therapy was started to improve muscle weakness in both legs on POD 16, and aerobic exercise using a cycle-ergometer was started on POD 24. OUTCOMES The 6-minute walking distance improved from 324 m on POD 14 to 501 m on POD 28. The patient could walk 4000 to 5000 steps per day at hospital discharge, and was discharged home on POD 32. There were no adverse events, including worsening hepatic or renal function, during the rehabilitation period. One month after discharge, the patient was able to perform 30 to 40 minutes of aerobic exercise every day, and returned to work 5 months after discharge. LESSONS This case shows that early rehabilitation intervention immediately after SLKT safely and rapidly improved physical performance without adverse events. The results in the present case suggest that regular physical assessment and appropriate interventions with a variety of exercise modalities can contribute to improved physical performance in SLKT patients.

Abstract
Aim This study evaluated the relationship between the relative dose intensity (RDI) and the prognosis to assess the optimal duration of adjuvant chemotherapy for pancreatic cancer. Patients and Methods From 2013 to 2018, 119 patients with pancreatic cancer underwent radical surgery. After excluding five patients who underwent R2 resection, three with stage IV disease, and two with adjuvant chemotherapy other than S-1, 109 cases were evaluated. They were classified into four groups based on the RDI for the total dosage of S-1: group 1: <50%, group 2: 50% to <80%, group 3: 80% to ≤125%, and group 4: >125%. Results The number of patients in each group were 48, 20, 30 and 11, with median ages of 74, 73, 66 and 74, respectively. Median estimated glomerular filtration rate was 75, 72, 89 and 77 ml/min/1.73 m2, respectively, demonstrating statistically significant differences. The corresponding median and 5-year overall survival rates were: 378 days and 17.9%; 1,011 days and 35.1%; 1,246 days and 41.6%; 1,389 days and 10.6%. Using group 1 as a reference, the adjusted hazard ratio was 0.39 for group 2, 0.36 for group 3, and 0.30 for group 4; all were statistically significant. Conclusion The higher the RDI of S-1 in adjuvant chemotherapy, the better the overall survival. Therefore, 1 year of adjuvant chemotherapy with S-1 in pancreatic cancer may be preferable to 6 months.

Abstract
BACKGROUND Neuroblastoma is the most common extracranial solid tumor in childhood. Stage 4S neuroblastoma is a unique subset of neuroblastoma characterized by a favorable course and potentially low malignancy with a high rate of spontaneous tumor regression. However, recent reports have shown that there is a subgroup of patients with stage 4S neuroblastoma characterized by MYCN amplification, chromosomal aberrations, age of < 2 months at diagnosis, and significantly poorer outcomes. CASE PRESENTATION A 1-month-old male infant with a huge abdominal tumor was transferred to our hospital and diagnosed with stage 4S neuroblastoma. The patient showed respiratory distress due to abdominal compartment syndrome secondary to massive hepatic invasion, and he required a silo operation and mechanical ventilation. After chemotherapy using carboplatin and etoposide, the infiltrative massive hepatic invasion was resolved and the abdominal compartment syndrome gradually improved; however, liver dysfunction as evidenced by hyperbilirubinemia, coagulopathy, and hyperammonemia continued. At the age of 3 months, living-donor liver transplantation was performed for treatment of sustained liver failure using a reduced lateral segment graft from the patient's father. Post-transplant liver function recovered immediately. Examination of the explanted liver demonstrated that the majority of liver tissue had been replaced by fibroblastic cells after massive hepatocyte dropout. There were only small areas of residual neuroblastoma cells in the liver specimen. The patient was discharged from the hospital 5 months after transplantation with home intermittent respiratory support. At the time of this writing (23 months after liver transplantation), he was in good condition with no signs of recurrence of neuroblastoma. CONCLUSIONS We have herein presented a case of successful pediatric living-donor liver transplantation for sustained liver failure even after resolution of infiltrative massive hepatic invasion of stage 4S neuroblastoma. Our case clearly shows that liver transplantation can be added as an appropriate extended treatment option for liver failure after resolution of stage 4S neuroblastoma.

Abstract
The success of islet transplantation in both basic research and clinical settings has proven that cell therapy has the potential to cure diabetes. Islets intended for transplantation are inevitably subjected to damage from a number of sources, including ischemic injury during removal and delivery of the donor pancreas, enzymatic digestion during islet isolation, and reperfusion injury after transplantation in the recipient. Here, we found that protein factors secreted by porcine adipose-tissue mesenchymal stem cells (AT-MSCs) were capable of activating preserved porcine islets. A conditioned medium was prepared from the supernatant obtained by culturing porcine AT-MSCs for 2 days in serum-free medium. Islets were preserved at 4°C in University of Wisconsin solution during transportation and then incubated at 37°C in RPMI-1620 medium with fractions of various molecular weights prepared from the conditioned medium. After treatment with certain fractions of the AT-MSC secretions, the intracellular ATP levels of the activated islets had increased to over 160% of their initial values after 4 days of incubation. Our novel system may be able to restore the condition of isolated islets after transportation or preservation and may help to improve the long-term outcome of islet transplantation.Abbreviations: AT-MSC, adipose-tissue mesenchymal stem cell; Cas-3, caspase-3; DAPI, 4,6-diamidino-2-phenylindole; DTZ, dithizone; ES cell, embryonic stem cell; FITC, fluorescein isothiocyanate; IEQ, islet equivalent; INS, insulin; iPS cell, induced pluripotent stem cell; Luc-Tg rat, luciferase-transgenic rat; PCNA, proliferating cell nuclear antigen; PDX1, pancreatic and duodenal homeobox protein-1; UW, University of Wisconsin; ZO1, zona occludens 1.

Abstract
Abstract:
The aim of this article is to review the antiviral activity of plants traditionally used in indigenous medicine in Sri Lanka, their therapeutic potential, chemistry, and botany. Viral infections represent an increasing threat to humans worldwide. Conventional antiviral drugs are available against respiratory viruses. Naturally occurring antiviral activity of medicinal plants was used for centuries in the country’s rich traditional medicine system consisting of Ayurveda, Siddha, Unani, and Deshiya Chikitsa. Traditional physicians cure diseases, including those that originate from viruses, through herbal medicine. To complement this, about 1430 species representing 838 genera, equivalent to 45% of the entire flowering plant community, are considered medicinal. The present article attempts to review the essence of decades of discoveries on antiviral and related properties of 21 medicinal plants, Allium sativum L., Annona muricata L., Ardisia elliptica Thunb., Azadirachta indica A. Juss., Caesalpinia pulcherrima (L.) Sw., Coriandrum sativum L., Coscinium fenestratum (Gaertn.) Colebr., Hedyotis corymbosa (L.) Lam., Hemidesmus indicus (L.) R. Br., Justicia adhatoda L., Ocimum tenuiflorum L., Phyllanthus embilica L., Phyllanthus debilis Klein ex Willd., Piper longum L., Piper nigrum L., Solanum xanthocarpum Schrad & Wendl., Terminalia bellirica (Gaertn.) Roxb., Terminalia chebula Retz., Tinospora cordifolia (Wild) Miers., Vitex negundo L., Zingiber officinale Roscoe. Among the medicinal plants commonly used in Sri Lankan traditional medicine, Justicia adhatoda showed stronger anti-influenza virus activity, inhibiting virus attachment and replication, while Terminalia chebula consisting of chebulagic and chebulinic acids, demonstrated direct antiviral activity against sexually transmitted herpes simplex virus-2 (HSV-2).

Abstract
The aim of this study was to assess changes in the quality of life and psychological distress of patients with tongue cancer undergoing total/subtotal glossectomy (TG) or extended hemiglossectomy (HG) and free flap transfer. Differences between the two groups were compared using the Short Form 8-Item Health Survey (SF-8) and Hospital Anxiety and Depression Scale (HADS). Of the 43 patients with tongue cancer, 24 (56%) underwent TG and 19 (44%) underwent HG. The general health and social functioning scores in the SF-8 and depression in the HADS were significantly worse in the TG group than in the HG group at 12 months after surgery, indicating that patients in the TG group may experience social isolation and psychological distress, and have difficulty in employability even 12 months after surgery. In contrast, all items of the SF-8 in the HG group were nearly equal to those in the general population. Due to the extensive psychological impact on patients with tongue cancer who are planned for an extended resection, curative surgery with free flap transfer and multidisciplinary psychiatric support are essential to improve quality of life and manage psychological distress.

Abstract
BACKGROUND The influence and risk associated with an aberrant right hepatic artery, a common anatomical variation, during pancreatoduodenectomy for pancreatic ductal adenocarcinoma has not been fully investigated. The present study analyzed the impact of an aberrant right hepatic artery on local recurrence after pancreatoduodenectomy for pancreatic ductal adenocarcinoma. METHODS A total of 169 patients with pancreatic ductal adenocarcinoma who underwent pancreatoduodenectomy at 2 separate Japanese medical institutions were retrospectively analyzed. RESULTS Thirty of 169 patients (17.7%) presented with an aberrant right hepatic artery. The incidence of local recurrence was higher in the aberrant right hepatic artery group than in the normal right hepatic artery group (43.3 vs 21.5%, P = .017). The local recurrence-free survival was significantly poorer in the aberrant right hepatic artery group than in the normal right hepatic artery group (P = .011). A multivariate analysis found that the aberrant right hepatic artery was an independent risk factor for local recurrence (hazard ratio: 3.74, P = .017). In the aberrant right hepatic artery group, more frequent local recurrence was observed in patients with tumors situated ≤10 mm from the aberrant right hepatic artery root. However, local recurrence was not observed in 2 out of 3 patients with tumors ≤10 mm from the aberrant right hepatic artery root who underwent pancreatoduodenectomy with combined resection of the aberrant right hepatic artery. CONCLUSION The presence of an aberrant right hepatic artery in patients undergoing pancreatoduodenectomy for pancreatic ductal adenocarcinoma may be associated with an increased risk of postoperative local recurrence. Combined resection of the aberrant right hepatic artery may reduce local recurrence, especially for tumors near the root of the aberrant right hepatic artery.

Abstract
Context: Good health and longevity depend on dynamic interactions between biological, social, psychological, and environmental factors. Aging is globally a big challenge, particularly with the demographic transition, including population growth, and an emerging burden to society. Knowledge, behavior, diet, and consumption of animal source food were related to aging and emerged as the key factors modulating healthy aging. Objective: The study was designed to understand the main healthy aging factors, such as knowledge, social network, and diet of elders, and to derive mutual learning from it for healthy aging. Methods: A qualitative approach has been applied to explore health-related knowledge, attitude, and diet of elders from Ebetsu (Japan) and Tiassalé (Côte d’Ivoire) health districts, using focus group discussions and comparative context analysis between high- and low-income countries. Results: The study shows that living longer is a common feature of people in Japan compared to Côte d’Ivoire, where the life expectancy is still low. Both groups of elders have social networks that support them, and both offer their gained experience to society. While Japanese elders depend on pension and insurance for income and medical treatments, Ivorians depend mostly on their children and social network in old age. The worries of elders differ between the two regions. In Ebetsu, elder members of the community are concerned about the future burden they pose for the younger generation if they develop ill-health, making them more resilient to aging. In Taabo, elders are considered to be culturally and socially useful to the society. Elders in Ebetsu pointed out that for healthy aging, education on diet at a younger age, physical activities, and access to basic social services are the key aspects. This was not observed in Taabo’s context. Being inactive and dependent on others were described as the most worrying situations for elders in Ebetsu, as it is perceived to increase the risk of non-communicable diseases and anxiety. Elders in Ebetsu have good knowledge on what constitutes a healthy diet, and they believe that diversifying their diet, reducing portions, and substituting red meat with good animal and vegetable proteins are best eating practices to maintain good health. In Côte d’Ivoire, the diet is imbalanced and the whole family consumes the same meal made mainly with high-energy staples and little protein. However, it is observed in both societies that adopting a good diet is very expensive. Conclusion: The consciousness of aging is universal, but healthy aging varies according to the social systems, education, and knowledge on diet transition. Physical activities, protein–energy balance in diet, and social networks are the key for healthy aging in both contexts. The challenge is to find ways to increase knowledge regarding healthy aging and to strengthen the support system so that healthy aging becomes affordable.

Abstract
Background: Intracranial aneurysms of the distal middle cerebral artery are rare, and most etiologies are infection or dissection. We present an extremely rare intracranial fusiform thrombosed aneurysm of the distal middle cerebral artery with histopathological confirmation of a pseudoaneurysm. Case Description: Our patient, a 68-year-old female, was previously healthy and had no history of infection or trauma. A fusiform thrombosed aneurysm of the distal middle cerebral artery was detected incidentally. The patient was treated successfully with trapping and resection of the aneurysm followed by superficial temporal artery to middle cerebral artery anastomosis. Xanthochromic and hypertrophic arachnoid membranes around the aneurysm were noticed, and a thrombus was detected inside the lesion. The aneurysmal wall had hyalinized connective tissue incompletely surrounded with intima, with no media or adventitia. Pathologically, it was a pseudoaneurysm. Conclusion: We report an extremely rare case of a pseudoaneurysm of the distal middle cerebral artery. We discuss the etiology of the lesion, with a literature review, and propose that the appearance and increase of the pseudoaneurysm was followed by microbleed of an aneurysm unrelated to the branching zone.

Introduction
Antithrombotic therapy including antiplatelet agents and anticoagulants are prescribed for secondary prevention in patients with established cardiovascular disease. Although antithrombotic therapy is often interrupted before non-cardiac surgery with or without perioperative bridging anticoagulation, the impact on thrombotic and bleeding events remains uncertain.
Purpose
The aim of this study was to clarify the impact of perioperative interruption of anticoagulants on thrombotic and bleeding events in patients with established CVD undergoing elective non-cardiac surgery.
Methods
A total of 330 patients chronically treated with antithrombotic therapy for secondary prevention underwent elective non-cardiac surgery under general anesthesia, with the complete interruption of antithrombotic agents. The study endpoints included all-cause death, thrombotic events, and major bleeding complications after surgical procedures.
Results
Of 330 patients, 171 (51.8%) and 159 (48.2%) received antiplatelet agents and anticoagulants perioperatively. Atrial fibrillation (31.8%) and coronary artery disease (20.3%) were the major indications for antithrombotic regimens. Antithrombotic therapy was interrupted from 5 [2, 7] days before the surgery to 4 [2, 7] days postoperatively. Perioperative bridging therapy with unfractionated heparin was employed in 99 (30.0%) patients. During the hospitalization, 3 (0.9%) patients died due to non-cardiovascular causes. Thrombotic events and major bleeding occurred in 2 (0.6%) and 9 (2.7%) patients. Bridging therapy with heparin was non-significantly associated with an increased risk of bleeding events (5.1% vs. 1.7%, p = 0.09). In univariable and multivariable analyses, pre-operative hemoglobin level and operative duration were significantly associated with bleeding complications.
Conclusions
In the present study, complete interruption of antithrombotic therapy resulted in a few thrombotic events with a numerically higher rate of bleeding events in patients undergoing elective non-cardiac surgery. Pre-operative hemoglobin level and operative duration were significantly associated with post-operative bleeding complications.

Abstract
PURPOSE This study assessed the significance of measuring liver stiffness using virtual touch quantification before hepatectomy to predict posthepatectomy refractory ascites. METHODS A total of 267 patients with hepatocellular carcinoma who underwent hepatectomy were prospectively analyzed. Liver stiffness was defined as the median value of the virtual touch quantification (Vs; m/s) by acoustic radio-force-impulse-based virtual touch. RESULTS A multivariate analysis showed that Vs and the aspartate aminotransferase-to-platelet ratio index were independent risk factors for postoperative refractory ascites (odds ratio = 3.27 and 3.08, respectively). The cutoff value for Vs was 1.52 m/s (sensitivity: 59.5%, specificity: 88.6%) as determined by the analysis of the receiver-operating characteristic curve, and the area under the receiver-operating characteristic curve was 0.79. The cutoff value for the aspartate aminotransferase-to-platelet ratio was 0.952 (sensitivity: 65.5%, specificity: 82.9%), and the area under the receiver-operating characteristic curve was 0.75. CONCLUSIONS Vs is an independent risk factor for refractory ascites after hepatectomy. The measurement of liver stiffness by virtual touch quantification before hepatectomy can help estimate the risk of postoperative refractory ascites. Nonsurgical treatments should be considered for the management of patients who are at high risk for refractory ascites.

Abstract
Polyamines are important to the survival and activation of organs and tissues via a homeostatic cell-metabolic process, and the polyamine content in cytoplasm decreases with aging. Decreases in cellular polyamine have been known to augment mutagenesis and cell death. Thus, supplementary polyamine in food is important to the prevention of aging. Here we show the anti-aging effects of oral intake of polyamine using luciferase-transgenic rats. Healthy rats, 10–12 weeks old, were given foods containing 0.01% and 0.1% (w/w) of polyamine, as compared a control food without polyamine, for 4 weeks. Using a bioimaging system, the photon intensities seen in the whole bodies and livers of rats consuming 0.1% of polyamine in food were stronger than those in rats consuming 0.01% and 0% of polyamine. However, there were no differences between groups in other characteristics, such as liver damage and body weight. In conclusion, we found that polyamine intake can activate cells throughout the whole body, providing an anti-aging effect.

Abstract
Abstract
Background
Elevated serum uric acid level was reportedly associated with greater coronary lipid plaque. Xanthine oxidoreductase (XOR) is a rate-limiting enzyme in purine metabolism and believed to play important roles in coronary atherosclerosis. However, the relation of XOR to coronary lipid plaque and its mechanism are unclear.
Purpose
The aim of this study was to assess the impact of XOR on coronary lipid plaque and the associated factors with XOR in coronary artery disease (CAD).
Methods
Patients with stable CAD undergoing elective percutaneous coronary intervention under near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS) guidance were prospectively enrolled. They were divided into three groups according to serum XOR activities; low, normal, and high. Coronary lipid core plaques in non-target vessels were evaluated by NIRS-IVUS with lipid core burden index (LCBI) and a maximum LCBI in 4 mm (maxLCBI4mm). Systemic endothelial function and inflammation were assessed with reactive hyperemia index (RHI) and high-sensitivity C-reactive protein, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio.
Results
Of 68 patients, 26, 31, and 11 were classified as low, normal, and high XOR activity groups. LCBI (474.4±171.6 vs. 347.4±181.6 vs. 294.0±155.9, p=0.04) and maxLCBI4mm (102.1±56.5 vs. 65.6±48.5 vs. 55.6±37.8, p=0.04) were significantly higher in high XOR group than in normal and low XOR groups. Although RHI was significantly correlated with body mass index, diabetes, current smoking, and high-density lipoprotein cholesterol, no relation was found between XOR activity and RHI (Figure). There were also no relations between XOR activity and high-sensitivity C-reactive protein, neutrophil-to-lymphocyte ratio, or platelet-to-lymphocyte ratio (Figure).
Conclusion
Elevated XOR activity was associated with greater coronary lipid plaque in patients with stable CAD, without significant relations to systemic endothelial function and inflammation.

Abstract
Abstract
Introduction
Recent trials demonstrated favorable effects of statins on the clinical prognosis, partly through anti-inflammatory properties, in patients with coronary artery disease. However, this favorable effect has not been fully verified in patients with peripheral arterial disease (PAD). We hypothesized that statins exert different prognostic effects depending on the degrees of inflammation at the time of endovascular therapy (EVT).
Methods
This study is a subanalysis from the Toma-Code Registry that is a Japanese prospective cohort of 2,321 consecutive patients with PAD treated by endovascular therapy in hospitals from 2014 to 2016. After the exclusion of patients without information of C-reactive protein (CRP) at the time of index EVT, 2,039 patients including 1,039 statin users and 1,000 statin non-users were ultimately analyzed. The patient enrolled were divided into 4 categories depending on CRP level at the time of EVT; Low-CRP (<0.1 mg/dL), Intermediate-low-CRP (0.1–0.3 mg/dL), Intermediate-High-CRP (0.3–1.0 mg/dL), and High-CRP (>1.0 mg/dL). A composite of death, stroke, myocardial infarction, and major amputation as the primary endpoint of this study was compared between statin users and non-users in each CRP category.
Results
The composite endpoint occurred in 255 patients during the observation period. Overall, statin users had a significantly lower event rate than non-users (Log-rank test: P<0.001). However, there were no significant difference in the event rates between statin users and non-users in the Low-, and Intermediate-Low-CRP categories. Only in the Intermediate-High- and the High-CRP categories, statin users showed a significantly lower event rates than non-users (P=0.02 and P=0.008, respectively, Figures). Additionally, multivariate Cox regression analysis in the High-CRP group revealed that statin use was independently associated with the primary endpoint (adjusted hazard ratio: 0.67 [95% confidence interval: 0.45–0.99]), even after the adjustment of covariants.
Conclusion
Statins may exert a favorable prognostic effect in PAD patients with highly elevated CRP, but not in those with low to moderate CRP level.

Abstract
Abstract
Background
Coronary functional abnormalities including both epicardial and microvascular coronary artery spasm represent an important role responsible for myocardial ischemia in patients with angina and nonobstructive coronary artery disease. However, clinical characteristics associated with microvascular spasm (MVS) have not been fully evaluated.
Purpose
The aim of this study was to assess differences in clinical features between patients with MVS and epicardial coronary spasm.
Methods
A total of 732 consecutive patients with suspected angina who presented nonobstructive coronary arteries and underwent intracoronary acetylcholine provocation test were retrospectively enrolled in this study. Epicardial coronary spasm was defined as total or subtotal occlusion of epicardial coronary arteries accompanied by chest pain and/or ischemic electrocardiographic changes in response to acetylcholine provocation test. MVS was diagnosed when chest pain and/or ischemic electrocardiographic changes developed after administration of acetylcholine in the absence of epicardial coronary spasm. Clinical characteristics were compared between patients with MVS and epicardial coronary spasm.
Results
Of all patients, 83 patients (11%) had MVS, 367 (50%) had epicardial coronary spasm, and the other patients (39%) showed neither MVS nor epicardial coronary spasm. Patients with MVS tended to be older (65.6±12.7 vs. 63.0±12.3 years, P=0.088) and were more frequently female (60.2% vs. 41.1%, P=0.0016) in comparison with patients with epicardial coronary spasm. Patients with MVS were less likely to be smokers (8.6% vs. 22.9%, P=0.0018), while there were no significant differences in the other coronary risk factors such as hypertension, dyslipidemia, and diabetes mellitus. Serum uric acid were significantly lower in patients with MVS (4.9±1.1 vs. 5.4±1.3 mg/dl, P=0.0018).
Conclusion
Our study demonstrated that patients with MVS had distinctive clinical background from those with epicardial coronary spasm, suggesting different mechanisms may involve the development of MVS.

Abstract
Abstract
Background
The recent reperfusion therapy for ST-elevation myocardial infarction (STEMI) has made the length of hospital stay shorter without adverse events. CADILLAC risk score is reportedly one of the risk scores predicting the long-term prognosis in STEMI patients.
Purpose
To invenstigate the usefulness of CADILLAC risk score for predicting short-term outcomes in STEMI patients.
Methods
Consecutive patients admitted to our university hospital and our medical center with STEMI (excluding shock, arrest case) who underwent primary PCI between January 2012 and April 2018 (n=387) were enrolled in this study. The patients were classified into 3 groups according to the CADILLAC risk score: low risk (n=176), intermediate risk (n=87), and high risk (n=124). Data on adverse events within 30 days after hospitalization, including in-hospital death, sustained ventricular arrhythmia, recurrent myocardial infarction, heart failure requiring intravenous treatment, stroke, or clinical hemorrhage, were collected.
Results
In the low risk group, adverse events within 30 days were significantly less observed, compared to the intermediate and high risk groups (n=13, 7.4% vs. n=13, 14.9% vs. n=58, 46.8%, p<0.001). In particular, all adverse events occurred within 3 days in the low risk group, although adverse events, such as heart failure (n=4), recurrent myocardial infarction (n=1), stroke (n=1), and gastrointestinal bleeding (n=1), were substantially observed after day 4 of hospitalization in the intermediate and high risk groups.
Conclusions
In STEMI patients with low CADILLAC risk score, better short-term prognosis was observed compared to the intermediate and high risk groups, and all adverse events occurred within 3 days of hospitalization, suggesting that discharge at day 4 might be safe in this study population. CADILLAC risk score may help stratify patient risk for short-term prognosis and adjust management of STEMI patients.

Abstract
Abstract
Background
Vasospastic angina (VSA) accounts for the majority of angina cases with no epicardial stenosis and develops amongawide range of age, which is reportedly induced by coronary functional abnormalities including endothelial dysfunction and smooth muscle hypercontraction. However, the relation of noninvasive vascular function tests to VSA remains to be fully elucidated.
Purpose
The aim of this study was to assess differences in clinical characteristics and findings from noninvasive vascular function tests among groups by age in patients with VSA.
Methods
We enrolled a total of 732 patients with angina who underwent intracoronary acetylcholine provocation test. VSA was defined as total or subtotal occlusion of epicardial coronary arteries accompanied by chest pain and/or ischemic electrocardiographic changes in response to acetylcholine administration. Patients with VSA were divided into 3 groups by age (young [<50 years], intermediate [50–64 years], and elderly group [≥65 years]). Noninvasive vascular function test findings such as ankle-brachial index (ABI), brachial-ankle pulse wave velocity (baPWV), andpercentage of mean arterial pressure (%MAP) were compared among groups by age in patients with VSA.
Results
Of all patients, 367 (50.1%) were diagnosed as VSA with intracoronary acetylcholine test, including 66 (18.0%), 113 (30.8%), and 188 (51.2%) patients in the young, intermediate, and elderly groups. Among groups by age, there was no significant difference in gender (female, 31.8% vs. 40.7% vs. 44.7%, P=0.19). Patients in the young group were more often smokers and alcohol drinkers than those in the intermediate and elderly groups, while the prevalence of hypertension, dyslipidemia, and diabetes were lower in younger patients. A history of percutaneous coronary intervention was less frequently found in the young group compared tothe intermediate and elderly groups (7.6% vs. 16.8% vs. 20.7%, P=0.033). The baPWV was higher in the elderly group (1424±232 vs. 1537±247 vs. 1774±358 cm/s, P<0.0001), while there was no difference in ABI between the 3 groups. %MAP at arms was significantly and progressively decreased with an increase in age (54.0±4.5% vs. 53.0±2.6% vs. 51.2±2.8%, P<0.0001).
Conclusion
Our study demonstrated that there were distinct age-related differences in clinical characteristics of patients with VSA. The higher %MAP in younger patients suggests that more impaired endothelial dysfunction may play a role in the development of VSA in this age group.

Abstract
Abstract
Introduction
Although radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) has become a standard therapy, the ablation outcomes in patients undergoing hemodialysis (HD) has not been fully elucidated. The present study aimed to evaluate the clinical outcomes of RFCA for AF in patients undergoing HD.
Methods
Twenty-three patients undergoing HD (17 men, age 65±8 years, 19 paroxysmal AF) who underwent RFCA for drug-refractory AF in two institutes were enrolled in the study and defined as HD group. The clinical parameters, recurrence free rate and frequency of periprocedural complications were compared to 46 randomly selected age, gender and left atrial diameter matched controls not requiring HD defined as non-HD group (34men, age 67±7 years, 38 paroxysmal AF).
Results
The patients in HD group had a significantly lower body mass index (21±3 vs. 25±3 P<0.01), higher prevalence of coronary artery disease (30% vs. 10% P=0.04), and higher prevalence of congestive heart failure (52% vs. 10% P<0.01) compared to patients in non-HD group. Echocardiography indicated lower left ventricular ejection fraction (57±17% vs. 65±9% P=0.02), higher E/e' (20±8 vs. 12±4 P<0.01), higher tricuspid regurgitation pressure gradient (30mmHg vs. 24mmHg P<0.01) and more impaired left ventricular diastolic function in HD group. All the subjects underwent bilateral pulmonary vein isolation plus additional linear lesion. The number of ablation procedure was similar between the two groups (1.43±0.5 vs. 1.46±0.6 P=0.88). During the follow-up period of 37±25 months after the last procedure, the arrhythmia free rate was similar between the two groups (86% vs. 84% log-rank P=0.82). Vascular access complication occurred in two patients in HD group, and pericardial effusion occurred in one patient in non-HD group, while no life-threatening complications were observed in either group. Cardiogenic cerebral infarction occurred in one patient in non-HD group. Discontinuation of oral anticoagulation after the ablation was more often seen in the HD group compared to non-HD group (91% vs. 60% P<0.01).
Conclusions
Although patients undergoing HD had more impaired left ventricular systolic and diastolic function, RFCA for AF in patients with HD was shown to be as effective and safe as in non-HD patients. RFCA may be an efficient approach to manage AF in patients undergoing HD.

Abstract
Abstract
Background
Vasospastic angina (VSA) is considered as a cause of myocardial infarction with nonobstructive coronary arteries. Given the previous reports of higher incidence of cardiovascular events in young VSA patients, early diagnosis and optimal treatment are important for these patients. While acetylcholine provocation test (ACh test) for VSA diagnosis is well reported, ACh test among young patients is not as commonly performed, therefore its safety and usefulness for this patient subset have not been fully evaluated.
Purpose
The purpose of this study was to evaluate the safety and the proportion of positive results of ACh test for young patients.
Methods
Data from patients who underwent ACh test in our institution from May 2012 to September 2018 were retrospectively analyzed. A total of 669 patients were enrolled and divided into 2 groups according to age: Young group (Age≤50, n=106); and Senior group (Age>50, n=563).
Results
The senior group had a higher incidence of hypertension, dyslipidemia, diabetes mellitus, and coronary artery disease. On the other hand, the young group had a significantly higher incidence of current smoker and tendency of daily alcohol. The rate of positive ACh test was similar, and there were no significant differences in major or minor complications between the 2 groups.
Patient characteristics and outcome Young group Senior group p (n=106) (n=563) Age (years) 42.8±7.3 68.0±9.0 <0.001 Male (%) 56.6 52.2 0.407 Current smoker (%) 34.9 15.4 <0.001 Daily alcohol (%) 31.1 22.9 0.070 Hypertension (%) 33.0 66.6 <0.001 Dyslipidemia (%) 50.0 68.4 <0.001 Diabetes (%) 12.3 20.8 0.047 ACh positive (%) 52.8 49.9 0.581 Minor adverse event (%) 4.7 5.9 0.820 Major adverse event (%) 0.9 1.4 1.000 Major adverse event: composite of death, ventricular fibrillation, sustained ventricular tachycardia (VT), myocardial infarction and stroke. Minor adverse event: non-sustained VT and paroxysmal atrial fibrillation.
Conclusion
ACh provocation test for young patients can be safely performed, and the rate of positive results was similar to that of senior patients. In young patients suspected of having VSA, ACh test should be actively performed to identify optimal medical therapy for prevention of cardiovascular events.

Abstract
Abstract
Background
Atrial fibrillation (AF) ablation is the most commonly performed catheter ablation (CA) procedure today. The 2015 ACC/AHA/HRS Advanced Training Statement reported that the success rate of AF ablation is higher in high-volume centers than in low-volume centers. We tested whether the procedure proficiency of each operator was associated with the outcome of AF ablation, and whether the ablation outcome depended on whether contact force (CF)-guided catheters were used or not, in a high-volume center.
Methods
We conducted a retrospective observational study including all AF patients who underwent radiofrequency CA with or without CF support since 2016 at our hospital. The patients who underwent CA at other hospitals or underwent a balloon or surgical ablation in the first session were excluded. Each ipsilateral pulmonary vein (PV) pair was divided into 8 segments. The reconnection numbers and sites of the PV segment were evaluated in the second session. Operators were divided into the experienced group (≥100 AF cases/year, at least every 3 years) and developing group (other than the experienced group), respectively.
Results
Among 728 patients who underwent an initial AF ablation and were followed for 510±306 days, 131 (90 males, 65±10 years) received a second ablation procedure and were analyzed. A total of 260 and 264 PV isolations (PVI) were performed by the experienced and developing group operators in the initial ablation, respectively. Compared to the experienced group, the developing group had a longer procedure time for the PVI (35±15 vs. 28±10 min, p<0.001), higher frequency of reconnections of the PVs (73% vs. 59%, p=0.01) and higher number of reconnection gaps (2.1±2.0 vs. 1.5±2.0, p=0.02), respectively. There were no significantly differences in the number of gaps between the catheters with and without CF (1.6±2.0 vs. 1.4±2.0, p=0.65) in the experienced group, however, in the developing group a smaller total number of gaps (1.5±1.6 vs. 2.4±2.1, p=0.006) and less frequency reconnection gaps of the posterosuperior segment of the right PV (10% vs. 45%, p=0.005) were seen with catheters with CF than without. There was no significant difference in the procedure time for the PVI between catheters with and without CF.
Conclusions
The operator proficiency may predict the outcome after AF ablation even in high-volume centers. It is preferable to perform PVI with a CF-sensing catheter for operators without adequate proficiency.

Abstract
Abstract
Background
Sustained ventricular arrhythmias (VAs) and death are feared events post myocardial infarction (post-MI). Patients with heart failure post-MI have higher risk of VAs, compared to those without heart failure. Although the risk of sudden cardiac arrest and death post-MI isn't small, previous clinical trials have failed to demonstrate the benefit of early use of implantable cardioverter defibrillators. Moreover, little is known about the relationship between the acute phase and the late phase VAs in patients with heart failure post-MI.
Purpose
The aim of this study was to determine the predictors of the late phase VAs in patients with heart failure post MI.
Methods
We retrospectively analyzed our database of MI patients from January 2012 to September 2016.
Results
A total of consecutive 460 post-MI patients were included in this study (age, 67±12 year-old; male, 336 (73%); STEMI, 281 (61%)). All the patients underwent primary percutaneous coronary intervention. Of those, 90 patients (20%) had depressed left ventricular ejection fraction (LVEF) ≤35%. After a mean follow up period of 30±16 months, 45 patients (50%) had VAs after MI. Among them, 35 patients (78%) had VAs within 48 hours after MI onset, 8 patients (18%) within 7 days 48 hours later, and 21 patients (47%) more than 7 days. Cox-regression analysis showed that VAs within 7 days 48 hours later after MI onset was significantly related to sustained VAs more than 7 days after MI onset (Hazard Ratio, 4.97; 95% Confidence Interval, 1.31–18.9; p=0.019).
Conclusions
VAs in the sub-acute phase after MI predicted sustained VAs in the late phase in this population. Prompt initiation of aggressive antiarrhythmic therapies, including catheter ablation, after MI should be considered to reduce the mortality.

Abstract
Fluorescence-activated cell sorting (FACS) is a powerful tool for analyzing stem cells. When using fixed cells, however, it is sometimes difficult to analyze RNA extracted from sorted cells due to RNA degradation. We established a protocol for immunocytochemistry before FACS to prevent RNA degradation. Cells were fixed with a methanol-based fixative (UM-Fix), then subjected to immunocytochemistry. The addition of RNase inhibitor and dithiothreitol (DTT) to some buffers used for immunocytochemistry increased RNA integrity after cell recovery. We found increased copy numbers of mRNA in recovered cells using quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis. When RNase inhibitor and DTT were added, amplification of mRNA using T7 promoter was possible with RNA extracted from recovered cells after FACS. Our protocol ensures high quality RNA in cells recovered by FACS; therefore, gene expression analysis with a smaller number of cells is possible using pre-amplification of mRNAs. Our protocol for immunocytochemistry also might be applicable to RNA recovery after immunostaining.

Abstract
Water, methane, and ammonia are commonly considered to be the key components of the interiors of Uranus and Neptune. Modelling the planets' internal structure, evolution, and dynamo heavily relies on the properties of the complex mixtures with uncertain exact composition in their deep interiors. Therefore, characterising icy mixtures with varying composition at planetary conditions of several hundred gigapascal and a few thousand Kelvin is crucial to improve our understanding of the ice giants. In this work, pure water, a water-ethanol mixture, and a water-ethanol-ammonia "synthetic planetary mixture" (SPM) have been compressed through laser-driven decaying shocks along their principal Hugoniot curves up to 270, 280, and 260 GPa, respectively. Measured temperatures spanned from 4000 to 25000 K, just above the coldest predicted adiabatic Uranus and Neptune profiles (3000-4000 K) but more similar to those predicted by more recent models including a thermal boundary layer (7000-14000 K). The experiments were performed at the GEKKO XII and LULI2000 laser facilities using standard optical diagnostics (Doppler velocimetry and optical pyrometry) to measure the thermodynamic state and the shock-front reflectivity at two different wavelengths. The results show that water and the mixtures undergo a similar compression path under single shock loading in agreement with Density Functional Theory Molecular Dynamics (DFT-MD) calculations using the Linear Mixing Approximation (LMA). On the contrary, their shock-front reflectivities behave differently by what concerns both the onset pressures and the saturation values, with possible impact on planetary dynamos.

Abstract
BACKGROUND It was demonstrated that polyamines ameliorate ischemia-reperfusion injury (IRI) and promote regeneration in the liver. An optimal protocol of polyamine treatment remains unknown in the clinical setting. We examined 2 types of administration methods using rat models. METHODS Experiment 1: evaluation of pharmacokinetics of polyamines. Experiment 2: for 3 days preoperatively and 5 days postoperatively, polyamines were given to male Lewis rats in the following three groups: the control group, no polyamine administration; the chow group, 0.05% polyamines mixed in chow; the bolus group, polyamines (200 μmol/kg) given by gastric tube once a day. All rats received 70% hepatectomy after 40 min of warm IRI. Postoperatively, IRI and regeneration were evaluated with assessment of serum levels of hepatic enzymes, histology and immunohistochemistry of liver tissue, and measurement of remnant liver weight. RESULTS The blood concentrations of polyamines in the portal vein increased at 1 h of bolus administration, while they did not increase without the bolus. The bolus group was significantly associated with lower serum levels of aspartate/alanine aminotransferases (p < 0.05), decreased hepatocyte congestion, vacuolization and necrosis in histopathological scoring (p < 0.05), a lower number of TUNEL-positive hepatocytes (p < 0.05), higher remnant liver weight at 24, 48, and 168 h (p < 0.05), and a higher Ki-67 labeling index (24 h, p < 0.01) compared with the chow group. CONCLUSION The bolus administration of polyamines was more effective in ameliorating IRI and promoting regeneration than chow administration. Perioperative bolus administration of polyamines might be an optimal treatment, when clinically applied.

Abstract
Abstract
(Background) SUVmax levels (maximum radioactivity concentration per a pixel) on FDG-PET reflect glucose uptake and it is clinically useful as a prognostic factor. It is reported that breast cancer with high levels of SUVmax causes insufficient glucose concentration in stromal tissue, which results in suppressed cytotoxic T-lymphocytes function. These data may indicate that the prognostic significance of SUVmax levels is influenced by local immune environment of breast cancer. The aim of this study is to investigate whether local immune responses of breast cancer affect correlation of SUVmax levels and prognosis.
(Method) The 278 invasive breast cancer patients were recruited who underwent surgery at Hyogo College of Medicine Hospital and whose SUVmax levels in the breast were examined before surgery or neo-adjuvant therapy. The cutoff value of SUVmax levels was set at 3.585. Tumor infiltrate lymphocytes (TILs) were evaluated as a local immune response and the distributions of TILs were divided into three groups, inflamed (intra-tumoral lymphocytes, Inf), immune excluded (peri-tumoral lymphocytes, IE) and immune desert (very few lymphocytes, ID). During follow-up period (median 39 months), 21 patients relapsed.
(Results) Relapse free survival (RFS) in the SUVmax-high group was significantly worse than in the SUVmax–low group (p=0.0026). There was no correlation between TILs distribution patterns and RFS. In the IE+ID group (175 patients) SUVmax levels were not correlated with prognosis, but in the Inf group (103 patients) RFS of SUVmax-high was significantly worse than of SUVmax-low (p=0.0051). In the multivariate analysis including nodal status and nuclear grade, SUVmax levels of the Inf group was an independent prognostic factor.
(Discussion and conclusion) SUVmax levels in primary lesions were correlated with prognosis only in the Inf group and were not in the IE+ID group. A significance of SUVmax levels as a prognostic factor may be diverse depending on the local immune environment of breast cancer. A novel therapeutic strategy such as inducing suppression of glucose uptake in cancer cells is suggested for breast cancer with immune inflamed.

Abstract
BACKGROUND The purpose of this study was to examine the impact of pretreatments on outcomes after living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC). METHODS From February 1999 to March 2015, 223 patients underwent LDLT for HCC. Until December 2006, there was no restriction in patient selection criteria regarding the number and size of tumors, following which we implemented the Kyoto criteria (tumor number ≤10, maximal diameter ≤5 cm, and des-gamma-carboxy prothrombin ≤400 mAU/ml) since January 2007. RESULTS Of 223 patients, 156 had a history of pretreatments. Among 101 patients meeting the Milan criteria at the initial diagnosis, 38 progressed to beyond the criteria at liver transplantation (LT). Twenty-two out of 38 met the Kyoto criteria, and their survival and recurrence rates were significantly better than those of patients exceeding the Kyoto criteria (P = 0.004 and 0.035, respectively). Regarding the number of pretreatments (0 vs. 1-4 vs. ≥5), recurrence rate was significantly higher in the ≥5 pretreatments group than the 0 group. However, for patients meeting the Kyoto criteria, there were no significant differences in recurrence rates between these three groups. CONCLUSION Better outcomes will be achieved by performing LT for HCCs meeting the Kyoto criteria even after repeated pretreatments.

Abstract
Osteoarthritis (OA) is a potentially disabling disease whose progression is dependent on several risk factors. OA management usually involves the use of non-steroidal anti-inflammatory drugs (NSAIDs) that are the primary pharmacological treatments of choice. However, NSAIDs have often been associated with unwanted side effects. Cyclooxygenase (COX)-2 specific inhibitors, such as celecoxib, have been successfully used as an alternative in the past for OA treatment and have demonstrated fewer side effects. While abundant data are available for the clinical efficacy of drugs used for OA treatment, little is known about the disease-modifying effects of these agents. A previous review published by Zweers et al. (2010) assessed the available literature between 1990 and 2010 on the disease-modifying effects of celecoxib. In the present review, we aimed to update the existing evidence and identify evolving concepts relating to the disease-modifying effects of not just celecoxib, but also other NSAIDs. We conducted a review of the literature published from 2010 to 2016 dealing with the effects, especially disease-modifying effects, of NSAIDs on cartilage, synovium, and bone in OA patients. Our results show that celecoxib was the most commonly used drug in papers that presented data on disease-modifying effects of NSAIDs. Further, these effects appeared to be mediated through the regulation of prostaglandins, cytokines, and direct changes to tissues. Additional studies should be carried out to assess the disease-modifying properties of NSAIDs in greater detail.

Abstract
BACKGROUND Skeletal muscle depletion, referred to as sarcopenia, has been shown to be an independent predictor of lower disease-free and overall survivals in various kinds of diseases. The quality of skeletal muscle has recently attracted much attention as a new parameter of sarcopenia, but its impact on surgical complications is still unknown. METHODS A retrospective analysis of 492 patients undergoing hepatectomy for hepatocellular carcinoma (HCC) in our institution between April 2005 and December 2014 was performed. The quality of skeletal muscle was evaluated by intramuscular adipose tissue content (IMAC) using preoperative CT imaging at the umbilical level. The impact of sarcopenia on postoperative complications and the predictors of surgical complications after hepatectomy for HCC were analyzed. RESULTS Patients with high IMAC were older and had higher body mass index, higher indocyanine green retention test at 15 min, and more operative blood loss. Among 492 patients, 108 (22 %) patients had major postoperative complications (Clavien grade ≥ III), and infectious complications were found in 74 (15 %) patients. Twelve (2 %) patients died from postoperative complications. On multivariate analysis, preoperative high IMAC was an independent risk factor for increased major postoperative complications [odds ratio (OR) 1.580; P = 0.049] and infectious complications (OR 1.903; P = 0.021). CONCLUSIONS Preoperative muscle steatosis evaluated with IMAC was closely correlated with increased postoperative complications, especially infectious complications. The preoperative nutritional intervention and rehabilitation might lead to the improvement of postoperative outcomes after hepatectomy for HCC.

Abstract
The outcomes of liver transplantation (LT) from donation after cardiac death (DCD) donors remain poor due to severe warm ischemia injury. Perfluorocarbon (PFC) is a novel compound with high oxygen carrying capacity. In the present study, a rat model simulating DCD LT was used, and the impact of improved graft oxygenation provided by PFC addition on liver ischemia/reperfusion injury (IRI) and survival after DCD LT was investigated. Orthotopic liver transplants were performed in male Lewis rats, using DCD liver grafts preserved with cold University of Wisconsin (UW) solution in the control group and preserved with cold oxygenated UW solution with addition of 20% PFC in the PFC group. For experiment I, in a 30-minute donor warm ischemia model, postoperative graft injury was analyzed at 3 and 6 hours after transplantation. For experiment II, in a 50-minute donor warm ischemia model, the postoperative survival was assessed. For experiment I, the levels of serum aspartate aminotransferase, alanine aminotransferase, hyaluronic acid, malondialdehyde, and several inflammatory cytokines were significantly lower in the PFC group. The hepatic expression levels of tumor necrosis factor α and interleukin 6 were significantly lower, and the expression level of heme oxygenase 1 was significantly higher in the PFC group. Histological analysis showed significantly less necrosis and apoptosis in the PFC group. Sinusoidal endothelial cells and microvilli of the bile canaliculi were well preserved in the PFC group. For experiment II, the postoperative survival rate was significantly improved in the PFC group. In conclusion, graft preservation with PFC attenuated liver IRI and improved postoperative survival. This graft preservation protocol might be a new therapeutic option to improve the outcomes of DCD LT. Liver Transplantation 23 1171-1185 2017 AASLD.
