Abstract
Abstract
Background
Carotid atherosclerosis such as increased intima-media thickness (IMT) is associated with poor cardiovascular outcome. On the other hand, protein-energy wasting (PEW) or malnutrition, currently considered to be due to inflammatory process rather than poor nutritional intake, is highly prevalent in in chronic kidney disease (CKD) patients, particularly those on haemodialysis (HD). We investigated the association of carotid atherosclerosis, PEW and inflammation, and their joint role with prediction of mortality in chronic HD patients.
Methods
Carotid ultra-sound was performed in a total of 774 CKD patients stably undergoing HD therapy. Carotid atherosclerosis is defined as IMT>0.8mm as median value with hyperechoic plaque. Geriatric nutritional risk index (GNRI) which calculated from serum albumin levels, body weight and height as a surrogate marker of the PEW, and C-reactive protein (CRP) were measured at the same point. Patients were followed-up for 7 years.
Results
Declined GNRI and elevated CRP levels were independently associated with carotid atherosclerosis [odds ratio (OR) 0.96, 95% confidence interval (CI) 0.93–0.98, p=0.0082 and OR 1.30, 95% CI 1.04–1.64, p=0.019, respectively] accompanied with age (OR 1.03, 95% CI 1.01–1.05, p=0.0024) and hypertension (OR 1.78, 95% CI 1.12–2.91, p=0.013). During follow-up period (median of 67 months), 180 patients (23.3%) died. Carotid atherosclerosis [62.7% vs. 79.3% for 7-year survival rate, hazard ratio (HR) 1.57, 95% CI 1.12–2.16, p=0.0078], GNRI<91.2 as an established cut-off value (58.8% vs. 83.7%, HR 1.87, 95% CI 1.35–2.59, p=0.0002) and CRP>1.1 mg/l as a median value (65.8% vs. 88.6%, HR 2.87, 95% CI 2.00–4.22, p<0.0001) were identified as independent predictors of mortality after adjustment for other confounders. When patients were divided into groups according to number of these three risk factors, 7-year Kaplan-Meier survival rate was 92.7%, 91.1%, 56.8% and 37.2% among groups with no risk factor, any 1 risk factor, any 2 risk factors and all risk factors, respectively (p<0.0001 for trend). After adjustment for other confounders, patients with any 1, any 2 and all risk factors had 2.21-fold (95% CI 1.26–4.14), 5.44-fold (95% CI 3.13–10.1) and 7.19-fold (95% CI 3.67–14.6) higher risk for mortality compared to those without any risk factor, respectively (p<0.0001 for trend).
Conclusions
Presence of carotid atherosclerosis was closely associated with both declined GNRI and elevated CRP levels in CKD patients on HD. Combination of these predictors was also additively associated with an increasing risk of mortality. These results clearly manifested the so-called malnutrition, inflammation and atherosclerosis (MIA) syndrome in this high-risk population.

Abstract
Abstract
Background
Leadless pacemaker (Micra, Medtronic, US) is a effective treatment for bradycardia and eliminates any malfunctions related to intravenous leads. However, some cases exhibit pericardial effusion, presumably associated to device implantation to right ventricular free-wall.
Objectives
The present study was carried out to find ECG features during ventricular pacing by Micra, which enabled to distinguish free-wall implantation from septal implantation without imaging modalities.
Methods
Consecutive 21 patients who received implantation of Micra in our facility were enrolled. Location of device in the right ventricle was evaluated using echocardiography or computed tomography in order to determine whether the device was implanted on the septum or the freewall. The difference of 12-lead ECG during ventricular pacing from Micra were analyzed between the septum group and the free wall group.
Results
According to the imaging investigation, body of Micra was clearly identifiable in 17 patients. The locations of device were classified into septum in 11 patients, free-wall in 4 patients, and indeterminate but apex in 2 patients. Further analysis regarding ECG was performed exclusively between the septum group and the free-wall group. In lead V1, peak deflection index (PDI) was significantly larger in free-wall group than septum group (0.64±0.06 vs. 0.45±0.10, P=0.005), whereas there was no difference of QRS duration, transitional zone and QRS pattern.
PDI of V1 and Location of LPM
Conclusion
PDI of V1 could be useful to predict implantation of Micra to free-wall and may potentially stratify the risk of postprocedural pericardial effusion.

Abstract
Abstract
Background
Hypoalbuminemia, a manifestation of protein-energy wasting or malnutrition, is commonly observed in patients with end-stage renal disease (ESRD), and is associated with chronic inflammation and increasing cardiovascular (CV) risk. Recently, C-reactive protein (CRP)/albumin ratio at discharge is reportedly a well-predictor of mortality in severe sepsis or cancer patients.
We investigated prognostic value of the CRP/albumin ratio at just starting haemodialysis (HD) therapy for CV morbidity and mortality in patients with ESRD.
Methods
A total of 1,548 ESRD patients were enrolled and were divided into quartiles according to CRP/albumin levels at initiation of HD; quartile 1 (Q1): <0.22, Q2: 0.23–0.54, Q3: 0.55–1.83 and Q4: >1.84. They were followed up for 10-year after starting HD therapy. Primary endpoint was CV events defined as hospitalization due to CV events such as cardiac disease, stroke and peripheral artery disease and CV death. We also evaluated the incremental value with C-index when CRP alone, albumin alone and the CRP/albumin ratio were added into a model with established risk factors.
Results
During follow-up period (median: 59 months), 512 cases experienced CV events (33.1%) including 165 cases of CV deaths (10.7%). Kaplan-Meier analysis shows that CV event-free survival rates for 10 years were 63.5%, 53.8%, 47.5% and 31.9% in Q1, Q2, Q3 and Q4, and that CV survival rates were 90.4%, 83.9%, 77.2% and 64.6% in Q1, Q2, Q3 and Q4, respectively (p<0.0001 in both). After adjustment for all baseline variables, elevated CRP/albumin ratio was identified as an independent predictor for CV events [hazard ratio (HR) 1.51, 95% confidence interval (CI) 1.11–2.07, p=0.0093 for Q2 vs. Q1, HR 1.79, 95% CI 1.33–2.42, p<0.0001 for Q3 vs. Q1and HR 2.27, 95% CI 1.70–3.07, p<0.0001 for Q4 vs. Q1, respectively]. As to CV mortality, similar results were obtained (HR 1.80, 95% CI 0.98–3.44, p=0.056 for Q2 vs. Q1, HR 2.56, 95% CI 1.45–4.71, p=0.0009 for Q3 vs. Q1 and HR 2.66, 95% CI 1.53–4.86, p=0.0004 for Q4 vs. Q1, respectively). Furthermore, adding the CRP/albumin ratio to a baseline model with established risk factors improved the C-index greater than that of CRP alone or albumin alone, respectively (0.715 from 0.692, p=0.0095 and from 0.683, p=0.0019)
Conclusion
The CRP/albumin ratio, which easily available from daily practice, could strongly stratify the risk of future CV morbidity and mortality in ESRD patients who need HD therapy.

Abstract
INTRODUCTION Hepatocyte transplantation is a promising alternate for the treatment of hepatic diseases. Hypothermic preservation of isolated human hepatocytes is potentially a simple and convenient strategy to provide on-demand hepatocytes in the quantity sufficient and the quality required for biotherapy. Isolated fresh hepatocytes include damaged cells that are also early apoptotic cells, which is not ideal for hepatocyte transplantation. However, this does not reflect cell viability, although it is considered that it adversely affects cell survival after transplantation. We aimed to harvest these hepatocytes and filter the apoptotic cells using a magnetic method to provide a transplantation source. MATERIALS AND METHODS Rat hepatocytes were isolated from caudate lobes using manual enzymatic perfusion. The hepatocyte yield was 5.3 ± 0.66 × 109 cells/g of liver tissue, with a viability of 82.3 ± 3.5%. Two samples of hepatocytes were freshly isolated, one using the magnetic method, and the other without. The magnetic method was performed using DynaMag-15 Magnet, and Annexin V Antibody was used on the early apoptotic cells. We evaluated the viability and plate efficiency of the cells after 24 hours at 37°C. Hepatocytes were isolated using cell separation method, and 30 × 106 cells were mixed with 1.0 mL of Dulbecco's Modified Eagle's Medium (DMEM) and directly injected into the spleen of Lewis rats (150-250 g) using 24-gauge needles. Blood samples were collected on days 0, 3, 7, and 14, and the blood albumin level was measured using enzyme-linked immunosorbent assay (ELISA):G1, control (medium injection); G2, fresh hepatocyte transplant using the magnetic method; and G3, fresh hepatocyte transplant without the magnetic method. RESULTS The viability was 84.9 ± 2% for fresh hepatocytes and 80.7 ± 1.2% for hepatocytes isolated using the magnetic method. The magnetic method does not damage the cells (73.5 ± 2% vs 35.2 ± 2% after 24 hours), preserving hepatocyte. The albumin level accepted significantly increased in the magnet-treated group compared with the nonmagnet group. Simultaneously, the spleen in which these hepatocytes were transplanted could be used to observe the hepatocytes; the cells were transplanted 14 days later, and the magnet-treated group had significantly higher levels of hepatocytes than the nonmagnet group. CONCLUSION We developed an effective technique for hepatocyte isolation for short-term preservation. As a result, we believe that transplantation not only improves the cell transplantation effect but also allows the cells to be stored efficiently using the magnetic method. These results demonstrate the usefulness of hepatocyte hypothermic preservation for cell transplantation.

Abstract
The novel WBN/Kob-Leprfa (fa/fa) congenic rat strain is considered a useful rat model of type 2 diabetes mellitus (T2DM). Accumulating findings suggest that low-grade inflammation is a causative factor in T2DM and that circulating levels of inflammatory cytokines are associated with insulin resistance. However, inflammatory cytokine profiles and their correlations with T2DM development/ progression in fa/fa rats have not been studied. In this study, we found that the fa/fa rats had considerably high plasma levels of interleukin (IL)-1α. Abundant cecal IL-1α mRNA expression and cecal inflammation with infiltrating IL-1α-producing macrophages was observed in fa/fa rats. Bone marrow derived macrophages from fa/fa rats expressed high levels of IL-1α upon lipopolysaccharide stimulation. Furthermore, Syphacia muris infection, which delays the onset of T2DM, reduced both plasma and cecal IL-1α levels in fa/fa rats. These results suggest that macrophage infiltration and IL-1α secretion comprise an important part of T2DM development and that S. muris infection inhibits pro-inflammatory cytokine expression in fa/fa rats.

Abstract
In higher plants, complex type N-glycans contain characteristic carbohydrate moieties that are not found in mammals. In particular, the attachment of the Lewis a (Lea) epitope is currently the only known outer chain elongation that is present in plant N-glycans. Such a modification is of great interest in terms of the biological function of complex type N-glycans in plant species. However, little is known regarding the exact molecular basis underlying their Lea expression. In the present study, we cloned two novel Lewis type fucosyltransferases (MiFUT13) from mango fruit, Mangifera indica L., heterologously expressed the proteins and structurally and functionally characterized them. Using an HPLC-based assay, we demonstrated that the recombinant MiFUT13 proteins mediate the α1,4-fucosylation of acceptor tetrasaccharides with a strict preference for type I-based structure to type II. The results and other findings suggest that MiFUT13s are involved in the biosynthesis of Lea containing glycoconjugates in mango fruits.

Abstract
Graft-versus-host disease (GVHD) is a major complication of allogenic bone marrow transplantation and involves the infiltration of donor CD4+ and/or CD8+ T cells into various organs of the recipient. The pathological role of human CD4+ and CD8+ T cells in GVHD remains controversial. In this study, we established two novel xenogeneic (xeno)-GVHD models. Human CD4+ or CD8+ T cells were purified from peripheral blood and were transplanted into immunodeficient NOD/Shi-scid IL2rgnull (NOG) mice. Human CD8+ T cells did not induce major GVHD symptoms in conventional NOG mice. However, CD8+ T cells immediately proliferated and induced severe GVHD when transferred into NOG mice together with at least 0.5 × 106 CD4+ T cells or into NOG human interleukin (IL)-2 transgenic mice. Human CD4+ T cell-transplanted NOG mice developed skin inflammations including alopecia, epidermal hyperplasia, and neutrophilia. Pathogenic T helper (Th)17 cells accumulated in the skin of CD4+ T cell-transplanted NOG mice. Further, an anti-human IL-17 antibody (secukinumab) significantly suppressed these skin pathologies. These results indicate that pathogenic human Th17 cells induce cutaneous GVHD via IL-17-dependent pathways. This study provides fundamental insights into the pathogenesis of xeno-GVHD, and these humanized mouse models may be useful as preclinical tools for the prevention of GVHD.

Abstract
In order to clarify the association between hyperglycemia during the early period after allogeneic stem cell transplantation (allo-SCT) and adverse outcomes, we retrospectively analyzed 563 consecutive patients who underwent allo-SCT at our institute between 2008 and 2015. Patients were categorized into three groups according to mean fasting blood glucose levels on days 0-7 (normoglycemia group<110 mg/dL, n=347; mild hyperglycemia group 110-149 mg/dL, n=192 and moderate/severe hyperglycemia group≥150 mg/dL, n=24). The median follow-up was 2.7 years. Patients in the moderate/severe hyperglycemia group had significantly worse characteristics. The cumulative incidences of 2-year non-relapse mortality (NRM) and the probabilities of 2-year overall survival (OS) in the normoglycemia, mild hyperglycemia and moderate/severe hyperglycemia groups were 7.5%, 19% and 29%, respectively (P<0.01), and 69%, 53% and 33%, respectively (P<0.01). In multivariate analyses, hyperglycemia was an independent predictor of high NRM (vs normoglycemia; mild hyperglycemia, hazard ratio (HR) 2.56, 95% confidence interval (CI) 1.56-4.18; moderate/severe hyperglycemia, HR 4.46, 95% CI 1.92-10.3) and poor OS (vs normoglycemia; mild hyperglycemia, HR 1.54, 95% CI 1.14-2.07; moderate/severe hyperglycemia, HR 1.61, 95% CI 0.89-2.91). In conclusion, hyperglycemia on days 0-7 after allo-SCT was associated with inferior outcomes.

Abstract
BACKGROUND Omalizumab, a humanized anti-IgE monoclonal antibody, has demonstrated efficacy in patients with severe allergic asthma. However, treatment responses vary widely among individuals. Despite a lack of data, free serum IgE levels following omalizumab treatment have been proposed as a marker of treatment responsiveness. METHODS In this prospective, observational study, we assessed the utility of biomarkers of type 2 inflammation in predicting omalizumab treatment responses, as determined by the absence of asthma exacerbation during the first year of treatment. Free serum IgE levels were monitored for 2 years to examine their association with baseline biomarker levels and the number of exacerbations. RESULTS We enrolled thirty patients who had been treated with omalizumab for at least 1 year, of whom 27 were treated for 2 years. Baseline serum periostin levels and blood eosinophil counts were significantly higher in patients without exacerbations during the first year of treatment than in patients with exacerbations. Baseline serum periostin levels, but not eosinophil counts, were negatively associated with free serum IgE levels after 16 or 32 weeks of treatment. Reduced free serum IgE levels during treatment from those at baseline were associated with reduced exacerbation numbers at 2 years. In 14 patients who continued to have exacerbations during the first year of treatment, exacerbation numbers gradually and significantly decreased over the 2-year study period, with concurrent significant reductions in free serum IgE levels. CONCLUSION Baseline serum periostin levels and serum free IgE levels during treatment follow-up may be useful in evaluating responses to omalizumab treatment.
