Abstract
Abstract
Background
The relationship between carotid artery ultrasound findings and clinical outcomes in percutaneous coronary intervention (PCI) patients has not been fully elucidated.
Purpose
To investigate the relationship between carotid artery ultrasound findings and cardiovascular risks in PCI patients.
Methods
This was a single-center retrospective study investigating 691 patients who underwent PCI and carotid ultrasound testing. Maximum carotid intima-media thickness (CIMT) was defined as the greatest CIMT at the maximally thick point among the common carotid artery, carotid bulb, and internal carotid artery. A carotid plaque was defined as vessel wall thickening with a CIMT ≥1.5 mm. The characteristics of carotid plaque (heterogeneity, calcification, or irregular/ulcerated surface) were evaluated visually. Patients were divided into those with and without heterogeneous carotid plaque (maximum CIMT ≥1.5 mm and heterogeneous texture). The endpoint was the incidence of a major adverse cardiovascular event (MACE) defined as a composite of cardiovascular death, myocardial infarction, and ischemic stroke.
Results
Among 691 patients, 312 were categorized as having a heterogeneous plaque. Patients with heterogeneous plaques were at a higher risk of MACE than those without (p=0.002). A heterogeneous plaque was independently associated with MACE after adjusting for covariates (hazard ratio [HR], 1.80; 95% confidence interval [CI], 1.06–3.04; p=0.03). Calcified or irregular/ulcerated plaques were correlated with a higher incidence of MACE but both were not independently associated with MACE (HR, 1.37; 95% CI, 0.70–2.67, p=0.36 and HR, 1.13; 95% CI, 0.66–1.93; p=0.66, respectively).
Conclusions
The presence of a heterogeneous carotid plaque in patients who underwent PCI predicted future cardiovascular events. These patients may require more aggressive medical therapy and careful follow-up.

Abstract
Abstract
Background
Worsening renal function (WRF) at short term after transcatheter aortic valve replacement (TAVR) is reportedly associated with subsequent poor clinical outcomes. We previously reported preoperative albuminuria predicted mid-term WRF after TAVR. However, the impact of albuminuria on short-term WRF after TAVR is unknown.
Methods
Overall, 206 patients who underwent TAVR for severe aortic stenosis were investigated retrospectively. Patients were divided into two groups according to the preoperative urinary albumin-to-creatinine ratio (ACR): high (ACR ≥30 mg/g) and low (ACR <30 mg/g). The incidence of 1-month WRF, defined as a decrease in estimated glomerular filtration rate (eGFR) ≥10% from baseline after TAVR, was investigated.
Results
More than half of the examined patients (n=106/206 [51.5%]) had a high ACR. Patients with a high ACR had significantly lower eGFR at baseline than those with a low ACR (49.3 [32.5–57.8] vs. 51.4 [37.7–65.8] mL/min/1.73 m2, p=0.03). Patients with a high ACR more frequently had acute kidney injury (8.5% vs. 1.0%, p=0.01) and 1-month WRF than those with a low ACR (29.2% vs. 12.0%, p=0.002). Multivariate analysis showed a high ACR was independently associated with 1-month WRF (odds ratio, 3.72; 95% confidence interval, 1.72–8.08; p<0.001). Meanwhile, eGFR <60 mL/min/1.73 m2 was not an independent predictor of 1-month WRF (odds ratio, 0.48; 95% confidence interval, 0.22–1.04, p=0.06).
Conclusions
Patients with preoperative albuminuria (ACR ≥30 mg/g) more frequently developed AKI and 1-month WRF after TAVR. Albuminuria was independently associated with 1-month WRF, suggesting albuminuria to be a universal predictor of deterioration of renal function at various time points.

Abstract
The present study investigated the effects of dietary supplementation combined with fish oil containing relatively low levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the inflammatory and nutritional status of patients with epithelial cancer. Fish oil capsules (498 mg EPA and 213 mg DHA) and dietary supplements (100 kcal and 5 g protein) were administered for 8 weeks to 20 patients with cancer and inflammation [C-reactive protein (CRP) ≥0.30 mg/dl]. Blood EPA levels increased significantly after 4 and 8 weeks, while no significant differences were observed in log-transformed (log) CRP levels, which were the major inflammatory indices in these patients. A declining trend was observed at 8 weeks after excluding 2 patients with suspected infection (P=0.06). A significant increase was observed from week 0 to week 8 for log interleukin-6 (IL-6) levels. After excluding the 2 patients with suspected infection, no significant difference was observed when comparing week 0 to week 8 for log IL-6. No deterioration in albumin or pre-albumin levels was observed. These results suggest that although suppression of acute inflammation associated with infection is difficult, intake of relatively low EPA and DHA supplements may be effective for mild chronic inflammation in patients with epithelial cancer without infection. Large-scale randomized clinical trials are required to make the final decision regarding efficacy. The study was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; 06/07/2018, UMIN000033309).

Abstract
BackgroundGenome-wide association studies (GWASs) have identified 29 disease-associated single nucleotide polymorphisms (SNPs) for systemic sclerosis (SSc) in non-human leukocyte antigen (HLA) regions (1-7). While these GWASs have clarified genetic architectures of SSc, study subjects were mainly Caucasians limiting application of the findings to Asians.ObjectivesThe study was conducted to identify novel causal variants for SSc specific to Japanese subjects as well as those shared with European population. We also aimed to clarify mechanistic effects of the variants on pathogenesis of SSc.MethodsA total of 114,108 subjects comprising 1,499 cases and 112,609 controls were enrolled in the two-staged study leading to the ever-largest Asian GWAS for SSc. After applying a strict quality control both for genotype and samples, imputation was conducted using the reference panel of the phase 3v5 1,000 genome project data combined with a high-depth whole-genome sequence data of 3,256 Japanese subjects. We conducted logistic regression analyses and also combined the Japanese GWAS results with those of Europeans (6) by an inverse-variance fixed-effect model. Polygenicity and enrichment of functional annotations were evaluated by linkage disequilibrium score regression (LDSC), Haploreg and IMPACT programs. We also constructed polygenic risk score (PRS) to predict SSc development.ResultsWe identified three (FCRLA-FCGR, TNFAIP3, PLD4) and four (EOMES, ESR1, SLC12A5, TPI1P2) novel loci in Japanese GWAS and a trans-population meta-analysis, respectively. One of Japanese novel risk SNPs, rs6697139, located within FCGR gene clusters had a strong effect size (OR 2.05, P=4.9×10-11). We also found the complete LD variant, rs10917688, was positioned in cis-regulatory element and binding motif for an immunomodulatory transcription factor IRF8 in B cells, another genome-wide significant locus in our trans-ethnic meta-analysis and the previous European GWAS. Notably, the association of risk allele of rs10917688 was significant only in the presence of the risk allele of the IRF8. Intriguingly, rs10917688 was annotated as one enhancer-related histone marks, H3K4me1, in B cells, implying that FCGR gene(s) in B cells may play an important role in the pathogenesis of SSc. Furhtermore, significant heritability enrichment of active histone marks and a transcription factor C-Myc were found in B cells both in European and Japanese populations by LDSC and IMPACT, highlighting a possibility of a shared disease mechanism where abnormal B-cell activation may be one of the key drivers for the disease development. Finally, PRS using effects sizes of European GWAS moderately fit in the development of Japanese SSc (AUC 0.593), paving a path to personalized medicine for SSc.ConclusionOur study identified seven novel susceptibility loci in SSc. Downstream analyses highlighted a novel disease mechanism of SSc where an interactive role of FCGR gene(s) and IRF8 may accelerate the disease development and B cells may play a key role on the pathogenesis of SSc.References[1]F.

Abstract
Previous studies have investigated the usefulness of microRNA (miRNA/miR) expression data for the early detection of colorectal cancer (CRC). However, limited data are available regarding miRNAs that detect CRC before clinical diagnoses. Accordingly, the present study investigated the early detectability of CRC by miRNAs using the preserved serum samples of the cohort participants affected with CRC within 2 years of study enrollment. First, the significant miRNAs were revealed using clinical CRC samples for a (seven early CRCs and seven controls) microarray analysis based on significance analysis of microarrays. Next, replicability was verified by reverse transcription-quantitative (RT-q)PCR (eight early CRCs and eight controls, together with 12 CRCs and 12 controls). Finally, early detectability was tested using the cohort samples of Japan Multi-Institutional Collaborative Cohort Study (17 CRCs and 17 controls) to reveal how a certain number of patients developed CRC within 2 years after participation. In the discovery phase, miRNA expression measurements were conducted using a 3D-Gene Human miRNA Oligo Chip for 2,555 miRNAs, and RT-qPCR analyses were performed to validate the replicability. In the first validation set with eight CRCs with early clinical stage and eight age- and gender-matched controls, miR-26a-5p and miR-223-3p demonstrated the highest diagnostic accuracy of area under the curve (AUC)=1.000 (sensitivity and specificity 100%). In an examination of the predictability of CRC incidence using pre-clinical cohort samples, miR-26a-5p demonstrated good predictability of advanced CRC incidence with an AUC of 0.840. Overall, the present study revealed serum miR-26a-5p as a potential early detection marker for CRC.

Abstract
OBJECTIVES Extending healthy life expectancy (HALE), defined as the average number of years that a person can expect to live in "full health" by taking into account years lived in less than full health due to disease and/or injury, is a common topic worldwide. This study aims to clarify the relationships between the Mediterranean diet score (MDS) and life expectancy (LE) and HALE globally using publicly available international data. SETTING Analyses were conducted on 130 countries with populations of 1 million or more for which all data were available. Individual countries were scored from 0 to 9 to indicate adherence to the Mediterranean diet according to the MDS scoring method. The supply of vegetables, legumes, fruits and nuts, cereals, fish, and olive oil per 1,000 kcal per country was calculated based on the Food and Agriculture Organization Corporate Statistical Database, with a score of 1 for above the median and 0 for below. The same method was used to calculate scores of presumed detrimental components (meat and dairy), with consumption below the median given a value of 1, and consumption above the median given a value of 0. For ethanol, a score of 1 was given for 10g to 50 g of consumption. We investigated the cross-sectional associations between the MDS and LE and HALE at birth in 2009, and the longitudinal associations between the MDS in 2009 and LE and HALE between 2009 and 2019, controlling for covariates at baseline using linear mixed models. RESULTS In the cross-sectional analysis, the MDS was significantly positively associated with LE (β=0.906 [95% confidence interval, 0.065-1.747], p=0.037) and HALE (β=0.875 [0.207-1.544], p=0.011) after controlling for all covariates. The longitudinal analysis also revealed significantly positive associations between the MDS and LE (0.621 [0.063-1.178], p=0.030) and HALE (0.694 [0.227-1.161], p=0.004) after controlling for all covariates. CONCLUSION The present study, based on an analysis using 10 years of international data, showed that countries with a higher MDS showed a positive association with HALE.

Abstract
Background:Potential efficacy and favorable safety profiles of tocilizumab (TCZ) have been demonstrated in patients with diffuse cutaneous systemic sclerosis (dcSSc) [1, 2]. However, clinical outcomes after dose-reduction or discontinuation of TCZ due to an improvement of skin thickness remain unclear.Objectives:To investigate the clinical outcomes after dose-reduction or discontinuation of TCZ in patients with dcSSc in a real-world setting.Methods:This is a single-center, retrospective, observational study using a database of consecutive SSc patients who visited our center between April 2014 and October 2020. For this study, we selected eligible patients from the database based on the following criteria: patients who (i) fulfilled the ACR/EULAR classification criteria, (ii) were classified as having dcSSc, (iii) had been treated with TCZ for at least 6 months, and (iv) were follow-up >6 months after TCZ introduction. Clinical information including demographic and clinical characteristics at TCZ introduction; dosing, administration route, and adherence of TCZ; and serial clinical parameters (modified Rondan total skin thickness score [mRSS], and percent predicted forced vital capacity [%FVC]), safety profiles, and outcomes after TCZ introduction regardless of TCZ continuation were extracted from the database.Results:Of 404 patients enrolled in the database, 13 dcSSc patients were eligible for this study. Baseline characteristics included a mean age of 51 ± 9 years, 85% female, disease duration of 27 ± 24 months, and mRSS of 19.5 ± 10.6. Seven patients (54%) had HRCT-confirmed ILD at baseline, and 9 (69%) were positive for anti-topoisomerase I antibody. Two (14%) and 11 (85%) were on mycophenolate mofetil and low-dose prednisolone (7.2 ± 6.0 mg/day), respectively. Seven patients (54%) each had active skin disease and elevated inflammatory markers defined in the phase III clinical trial [2], while only 4 (31%) fulfilled the inclusion criteria. TCZ was initially administered intravenously (8 mg/kg every 4 weeks) in 8 patients and subcutaneously in 5 (162 mg every 2 weeks in 4 and every week in one). At one year, mRSS was improved from 20.9 ± 11.4 to 10.7 ± 8.9 in 11 patients (p = 0.007), and %FVC was stable in 7 patients with ILD (76.8 ± 15.0 to 78.6 ± 16.1). During the observation period of 60.4 ± 26.7 months, 4 patients were treated with a stable dose of TCZ, while TCZ dose was reduced and/or discontinued in 9. Four of them discontinued TCZ due to adverse events (n = 2; acute lung injury and phlegmon) or prominent improvement of skin thickening (n = 2). Of 9 patients with dose reduction/discontinuation of TCZ, 4 patients who discontinued TCZ (n = 3) or received dose reduction of TCZ (n = 1) experienced a recurrence of progressive skin thickening together with inflammatory complications, including edematous induration of the skin, progression of ILD, polyarthritis, and/or pericarditis with increased inflammatory markers. The interval between dose-reduction/discontinuation of TCZ and clinical worsening ranged from 2 to 11 months. These manifestations were promptly improved by dose-escalation or resumption of TCZ in all patients except one who experienced progressive ILD and died of respiratory failure 27 months later.Conclusion:In dcSSc patients who experienced improvement of skin thickness during treatment with TCZ, dose-reduction or discontinuation of TCZ may result in a recurrence of the disease. Randomized comparative studies are necessary to examine optimal timing for dose-reduction or discontinuation of TCZ in dcSSc patients after improvement of skin thickness.References:[1]Khanna, D., et al., Safety and efficacy of subcutaneous tocilizumab in systemic sclerosis: results from the open-label period of a phase II randomised controlled trial (faSScinate).

Abstract
Background:Tocilizumab (TCZ) showed trends for improving skin fibrosis and prevented progression of lung fibrosis in patients with systemic sclerosis (SSc) in placebo-controlled randomised clinical trials (RCTs). However, safety and effectiveness of TCZ beyond these selected and enriched clinical trial populations in SSc is still unknown.Objectives:To assess safety and effectiveness of TCZ treatment compared to standard of care in SSc patients from the large, multicentre, observational, real-life EUSTAR network/database using propensity score matching.Methods:SSc patients from the EUSTAR network/database, who fulfilled the ACR/EULAR 2013 classification criteria, with a baseline and a follow-up visit at 12±3 months, receiving TCZ or standard of care (controls), were selected. The following variables were used for the propensity score matching (1:1): age at diagnosis, gender, disease subtype, baseline modified Rodnan skin score (mRSS), forced vital capacity (FVC), and diffusing capacity for carbon monoxide (DLCO), co-therapy with immunosuppressives, disease duration, and year of treatment. Primary endpoints were mRSS and FVC at 12±3 months follow-up compared between the groups, using paired t-tests. Secondary endpoints were the percentage of progressive/regressive patients for skin and lung at 12±3 months follow-up according to standard definitions (1,2). Sensitivity analyses assessed pre-processing decisions (selection of most recent vs. random observation for control patients with multiple suitable time intervals), as well as the matching method (optimal vs. exact matching). Missing values were addressed with 100-fold multiple imputation using chained equations. Safety data were analysed in all patients. The study including the statistical analysis plan was pre-registered at www.drks.de (DRKS-ID: DRKS00015537).Results:We identified 93 SSc patients treated with TCZ and 2370 SSc patients with standard of care who fulfilled the inclusion criteria. Forty nine (57.7%) of the TCZ treated patients were diffuse, eight patients were not classified, disease duration was (mean±SD) 6.35±5.40 years, their baseline mRSS was 15.05±10.85, and 76 (81.7%) received immunosuppressive therapy in addition to TCZ.Through multiple imputation and propensity score matching, 100 imputed sets of 93 pairs of TCZ/controls were generated. Comparison between groups showed consistent effects of TCZ across all pre-defined primary and secondary endpoints: mRSS was lower in the TCZ group (mean difference (95% confidence interval (CI)) -1.8 (-4.79 to 1.19), p=0.24, Figure 1A). Similarly, FVC % predicted was higher in the TCZ group mean difference (2.25, 95% CI -4.57 to 9.06), p=0.51, Figure 1B). Considering secondary endpoints, the percentage of skin progressors as well as lung progressors at follow up was lower in the TCZ group (odds ratio OR 0.67 (95% CI 0.07 to 6.41), p=0.74 and OR 0.53 (95% CI 0.16 to 1.7); p=0.2, respectively. Consistently, the percentage of regressors for skin (OR 1.6 (95% CI 0.56 to 4.54), p=0.38) and for lung (OR 1.74 (95% CI 0.66 to 4.58), p=0.26) was higher in TCZ. These results were robust regarding the sensitivity analyses. Safety analysis confirmed previously reported adverse event profiles.Conclusion:In this large, observational, controlled, real-life EUSTAR study, effectiveness of TCZ did not reach statistical significance compared to standard of care treatment but showed consistent positive effects of TCZ on skin and lung fibrosis across all pre-defined primary and secondary endpoints confirming data from recent RCTs.References:[1]Prediction of improvement in skin fibrosis in diffuse cutaneous systemic sclerosis: a EUSTAR analysis.

Abstract
BACKGROUND Systemic inflammation via host-tumor interactions is currently recognized as a hallmark of cancer. The aim of this study was to evaluate the prognostic value of various combinations of inflammatory factors using preoperative blood, and to assess the clinical significance of our newly developed inflammatory score in colorectal cancer (CRC) patients. METHOD In total 477 CRC patients from the discovery and validation cohorts were enrolled in this study. We assessed the predictive impact for recurrence using a combination of nine inflammatory markers in the discovery set, and focused on lymphocyte-C-reactive protein ratio (LCR) to elucidate its prognostic and predictive value for peri-operative risk in both cohorts. RESULTS A combination of lymphocytic count along with C-reactive protein levels demonstrated the highest correlation with recurrence compared with other parameters in CRC patients. Lower levels of preoperative LCR significantly correlated with undifferentiated histology, advanced T stage, presence of lymph node metastasis, distant metastasis, and advanced stage classification. Decreased preoperative LCR (using an optimal cut-off threshold of 6000) was an independent prognostic factor for both disease-free survival and overall survival, and emerged as an independent risk factor for postoperative complications and surgical-site infections in CRC patients. Finally, we assessed the clinical feasibility of LCR in an independent validation cohort, and confirmed that decreased preoperative LCR was an independent prognostic factor for both disease-free survival and overall survival, and was an independent predictor for postoperative complications and surgical-site infections in CRC patients. CONCLUSION Preoperative LCR is a useful marker for perioperative and postoperative management of CRC patients.

Abstract
Treatment of cancer patients undergoing chemotherapy with L-carnitine (LC) supplementation is becoming increasingly popular in the clinic. The present study aimed to examine the possible effects of polymorphisms in CPT1B and CPT2 (CPT1B G320D, S427C, c.282-18 C>T, and p.E531K, and CPT2 V368I) on the plasma concentration of carnitine in humans. The subjects were the 218 participants of the Iga Cohort Study. Differences in plasma-free carnitine levels by genotype were examined. Genotyping was conducted by polymerase chain reaction with confronting two-pair primers (PCR-CTPP). The plasma carnitine levels were significantly higher in males (P<0.001; Student’s t-test), and there was no significant difference in plasma carnitine levels between the age groups (P=0.202; ANOVA). One-way ANOVA revealed the plasma levels of carnitine were neither significantly different by CPT1B G320D, S427C, c.282-18 C>T, or p.E531K, nor by CPT2 V368I genotypes (P=0.133, P=0.538, P=0.636, P=0.509, and P=0.398, respectively). When analysis of covariance (ANCOVA) adjusted for age and sex was applied, the plasma levels of carnitine were not statistically significantly different according to these genotypes (P=0.299, P=0.715, P=0.980, P=0.851, and P=0.674, respectively). The present study did not identify any statistically significant differences in plasma carnitine levels between subjects with different CPT1 and CPT2 genotypes, suggesting that there may be no need to tailor treatments to patients’ genotypes when determining the dose/amount of LC to be administered to cancer patients undergoing palliative care.

Abstract
Abstract
Background
Mid-ventricular obstructive hypertrophic cardiomyopathy (MVO-HCM) has different blood flow dynamics from other phenotypes, but there are few detailed data on blood flow dynamics in the left ventricle.
Methods
4D-Flow MRI were performed at 1.5 T or 3 T with 9 MVO-HCM patients and 22 control patients (LVEF>50%, no wall motion abnormality). Myocardial infarction, severe valvular disease, HCM cases other than MVO were excluded. We calculated the cardiac function parameters and observed blood flow dynamics in the left ventricle using 4D-Flow MRI.
Results
LV mass was significantly higher in MVO-HCM group than in Control group (Control group; 73.3g vs MVO-HCM group; 109.5g, P=0.019). LVEF was higher in MVO-HCM group (Control group; 61.6% vs MVO-HCM group; 70.6%, P=0.026), but Stroke volume did not differ between the two groups (Control group; 68.8ml vs MVO-HCM group; 64.4ml, P=0.43).One or two vortices were observed in the left ventricle after opening the mitral valve. Two vortices were observed in 16 cases (72.7%) in the control group and 9 cases (100%) in the MVO-HCM group. Two vortices were formed on the anterior side and the posterior side. Blood flow pattern in which the vortex on the posterior side was formed to be the same size or larger than the vortex on the anterior side was observed only in the MVO-HCM group (Control group; 0% vs MVO-HCM group; 66.7%, P<0.001).
Streamline of MVO-HCM & Control
Conclusion
Characteristic blood flow patterns in the left ventricle of the MVO-HCM were revealed by using 4D-MRI. We thought that blood flow collides with the left ventricle wall due to the marked hypertrophy in the mid-ventricle, and normal vortex ring can not be formed in the MVO-HCM cases.

Abstract
Gastrointestinal cancer is one of the most common causes of mortality globally. The present study examined the influence of cytokine genetic polymorphisms [interleukin (IL)-1B C-31T, IL-1RN VNTR, IL-6 C-634G, IL-8 T-251A, IL-10 T-819C and IL-10 A-1082G] on clinical outcomes in patients with gastrointestinal cancer in palliative care. A total of 59 patients with gastrointestinal cancer who were admitted to Iga City General Hospital were analyzed. Genotyping was conducted using a polymerase chain reaction with confronting two-pair primers. Patients with at least one IL-1RN 2 allele demonstrated a significantly better survival (P=0.0275) while those with IL-6-634 G/G demonstrated a worse survival (P=0.0024). Multivariate analyses using the Cox proportional hazard model revealed that those with at least one IL-1RN 2 allele, IL-6-634 G/G or IL-10-1082 A/G had a significantly elevated adjusted hazard ratio of 9.20 (P=0.014), 41.01 (P=0.001) or 6.49 (P=0.046), respectively, compared with those with each homozygous wild-type polymorphism. In addition, the evaluation of weight loss by genotype revealed the potential influence of IL-10 T-819C genotype (P=0.072). IL-1RN, IL-6 and IL-10 polymorphisms were associated with the survival of patients with gastrointestinal cancer, suggesting the clinical feasibility of genetic testing in patients with gastrointestinal cancer in palliative care.

Abstract
OBJECTIVES We created a Traditional Japanese Diet Score (TJDS), and to clarify the relationship between TJDS and obesity, ischemic heart disease (IHD), and healthy life expectancy (HALE). DESIGN Ecological study. SETTING Food (g/day/capita) and energy (kcal/day/capita) supply was determined using the Food and Agriculture Organization of the United Nations Statistics Division database. The sum of characteristic traditional Japanese foods (beneficial food components in the Japanese diet: rice, fish, soybeans, vegetables, eggs, and seaweeds; food components rarely used in the Japanese diet: wheat, milk, and red meat) was divided as tertiles (beneficial food components: -1, 0, 1; rarely used food components: 1, 0, -1). Obesity rate was determined using the World Health Organization database. Incidence of IHD, HALE and smoking rate were determined using the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 database. Gross domestic product per capita, percentage of population > 65 years old, and health expenditure were determined using the World Bank database. Education years were obtained from the United Nations Educational, Scientific and Cultural Organization Institute for Statistics. Associations between TJDS and obesity, IHD and HALE were examined in 132 countries with a population of 1 million or greater using a general linear model controlled for co-variables. RESULTS TJDS was distributed from -6 to 7. TJDS was inversely correlated to obesity (β±SE; -0.70±0.19, p<0.001), IHD (-19.4±4.3, p<0.001), and positively correlated to HALE (0.40±0.14, p<0.01). CONCLUSIONS TJDS is a good indicator of a healthy diet, and applies to preventing obesity, IHD and extending HALE.

Abstract
We used clinical data from Iga General Hospital to examine the association between polymorphisms in MTR (methionine synthase) A2756G (rs1805087), MTRR (methionine synthase reductase) His595Tyr (rs10380), MTHFR (methylenetetrahydrofolate reductase) C677T (rs1801133), MTHFR A1298C (rs1801131) and SHMT (serine hydroxymethyltransferase) C1420T (rs1979277), which are genes involved in folate metabolism, and the risk of weight loss in patients with gastrointestinal cancers, with the aim of establishing personalized palliative care for each patient based on genetic information. The data from 59 patients (37 males and 22 females) with gastrointestinal cancers who visited the outpatient clinic for cancer chemotherapy and palliative care at Iga General Hospital from December 2011 to August 2015 were analyzed. There was no significant association between the single nucleotide polymorphisms (SNPs) in the folate metabolizing genes examined and weight loss defined as weight loss of more than 5 percent or more than 10 percent during the first 6 months after initiation of chemotherapy. We did not detect any significant association between any of the SNPs examined and overall survival of patients. The present study indicated that these SNPs have relatively limited or no roles in the genesis of cachexia in patients with gastrointestinal cancers; however, further investigations into the roles of these folate metabolizing genes in the context of cancer palliative care, from clinical, biological and epidemiological viewpoints are warranted.

Abstract
Serum transthyretin (TTR), also known as prealbumin, is a reliable nutritional indicator and an independent prognostic factor for maintenance hemodialysis patients. However, we recently reported that serum TTR levels did not affect protein-energy wasting (PEW). In this study, we investigated factors affecting serum TTR levels in 60 maintenance hemodialysis patients. The patients were divided into High-TTR and Low-TTR groups according to the median serum TTR level. Albumin levels were significantly higher and C-reactive protein (CRP) levels were significantly lower in the High-TTR group than in the Low-TTR group. Although body fat mass was significantly higher in the High-TTR group than in the Low-TTR group, no significant difference in body fat ratio were observed. These findings suggest that body fat mass is related to serum TTR levels, apart from factors such as albumin and CRP levels, which showed correlations with serum TTR levels. Because body fat mass is related to better survival in maintenance hemodialysis patients, it may contribute to the prognostic value of serum TTR levels. In addition, in such patients, it may be important to evaluate body fat mass rather than body fat ratio and to maintain the minimum necessary body fat mass. J. Med. Invest. 64: 222-227, August, 2017.

Abstract
BACKGROUND/AIM This study aimed to clarify the potential of modified Glasgow Prognostic Score (mGPS) as a prognostic biomarker and reveal the significance of fish oil (FO)-enriched nutrition in colorectal cancer (CRC). PATIENTS AND METHODS A total of 738 CRC patients from three different patient cohorts, including 670 patients in the biomarker study and 68 patients in the nutrition-intervention study, were analyzed. RESULTS High preoperative mGPS was significantly correlated with well-recognized disease progression factors and advanced UICC stage classification. In addition, high mGPS was an independent prognostic factor in both cohorts, especially in stage III and IV patients. These statuses were maintained in postoperative course and correlated with sarcopenia. Furthermore, FO-enriched nutrition suppressed systemic inflammatory reaction and improved skeletal muscle mass and prognosis, especially in CRC patients with mGPS 1 or 2. CONCLUSION Assessment of mGPS could identify patients with high-risk CRC, who might be candidates for FO-enriched nutrition.

Abstract
AIM Histamine receptor H3 (HRH3) has substantial neuropharmacological potential. Currently, knockout models of this receptor have been investigated only in mice. We characterized the expression of this receptor in the zebrafish and generated a zebrafish HRH3 knockout line. Using this model, we studied the role of HRH3 in important behaviours. We also analysed the effect of HRH3 knockout on monoaminergic systems, which has not been thoroughly studied in any animal model. METHODS Generation of a mutant zebrafish line using the CRISPR-Cas9 system. Analysis of locomotor and social behaviour. Expression of HRH3 was characterized using in situ hybridization. Analysis of monoamine networks using HPLC, immunohistochemistry and quantitative PCR. RESULTS We found that HRH3 knockout zebrafish larvae showed a shorter period of increased locomotion after a sudden onset of darkness, while the knockout larvae had a wild-type-like acute response to sudden darkness. Adult knockout fish showed decreased swimming velocity, although locomotor activity of knockout larvae was unaltered. Additionally, levels of dopamine and serotonin were significantly decreased in the knockout fish, while monoamine-related gene expression and immunohistochemistry patterns were unchanged. CONCLUSIONS Our results show that HRH3 knockout larvae adapt faster to sudden darkness, suggesting a role for this receptor in regulating responses to changes in the environment. The decreased levels of dopamine and serotonin provide the first direct evidence that knockout of HRH3 alters these systems.

Abstract
BACKGROUND In palliative care, prediction of life expectancy is one of the most crucial issues for patients, family and medical staff, in order to provide appropriate end-of-life care. The aim of this study was to formulate a new objective score to predict life expectancy within 1 week for terminally ill patients with cancer. PATIENTS AND METHODS Medical records were obtained from 187 terminally-ill patients with cancer who were admitted for palliative care. The biomarkers for a potential 'Objective Predictive Score' were assessed. RESULTS Profiling of blood parameters demonstrated that elevated levels of alanine aminotransferase (ALT), total bilirubin (T-bil), blood urea nitrogen (BUN), creatinine (Cr) and a decreased platelet count were significantly correlated with death within 1 week in a training cohort. Our formulated Objective Predictive Score was able to predict death within 1 week with high accuracy in a training and a validation cohort. CONCLUSION Our scoring system might enable the assessment of prognostication with higher accuracy in a terminal care setting.

Abstract
Large avulsed skin flaps of the lower extremity caused by degloving injuries eventually develop skin necrosis in most cases. The current treatment option involves excision of the degloved skin and reapplication as a full- or split-thickness skin graft. We considered that reattachment of avulsed skin flaps without excision would be theoretically beneficial, since some circulation may remain around the connected pedicle and thus facilitate graft take. Furthermore, securing the skin to the original anatomic position is much easier using retained landmarks. We treated a total of 12 patients (13 cases) with degloving injuries of the lower extremity. In all cases, the avulsed skin flap was defatted and sewn back to the original position, then negative-pressure wound therapy was applied over those grafts as a bolster for approximately 7 days. Most of the avulsed skin flap took excellently, particularly close to the connected pedicle. Nine cases did not need any additional surgical procedures. Four cases required secondary skin graft for a small area of open wound due to partial necrosis of the defatted skin, as well as the raw surface left by the primary skin defect in the initial operation. Primary reattachment of the avulsed skin flaps without excision is convenient and efficient to cover the open wound over the exposed fascia and periosteum in degloving injuries. This would potentially offer a better alternative to definitive wound closure.

Abstract
BACKGROUND AND OBJECTIVES The International Society of Renal Nutrition and Metabolism (ISRNM) has recently recommended the use of the term "protein-energy wasting" (PEW). PEW is a state of malnutrition with decreased body stores of protein and energy fuel in hemodialysis patients and is known as a risk factor for morbidity and mortality. We examined the prevalence of PEW and the characteristics of PEW patients in a hemodialysis center in Japan. METHODS AND STUDY DESIGN Fifty-nine outpatients undergoing maintenance hemodialysis at Iga City General Hospital were evaluated. We observed their biochemical data, body composition, dietary intake, and the number of steps prospectively. PEW was defined according to ISRNM criteria. RESULTS Nine patients (15% of total) were diagnosed as having PEW. Among indicators of PEW criteria, the relevance ratios of "reduced muscle mass" and "unintentional low dietary energy intake" were significantly higher in PEW than in non-PEW. The number of steps was lower, and serum levels of glucose and C-reactive protein were higher in PEW. CONCLUSION About 15% of Japanese hemodialysis patients are estimated to have PEW. Our results suggested that major contributing factors to PEW were reduced muscle mass, unintentional low dietary energy intake, lower amount of exercise, insulin resistance, and chronic inflammation.

Abstract
Expression of specific genes is a strategy of animal cells for adaptation to oxygen deficiency and the mechanism underlying the hypoxic activation of gene expression may be useful for efficient production of recombinant proteins by animal cells, because oxygen is a limiting factor in animal cell cultures. We prepared an animal cell line harboring the plasmid in which expression of a reporter gene, β-galactosidase, is controlled by an enhancer responsible for the hypoxic activation of gene transcription. The purpose of this paper is to understand this hypoxic production of recombinant proteins quantitatively by a mathematical model originally developed based on the following hypotheses; 1 lacZ (the reporter gene) is transcribed after HIF-1 protein complex is bound to the hypoxic enhancer, 2. β-galactosidase synthesis rate is limited at the transcription of lacZ, 3. HIF-1 is an inactive form under a normal oxygen concentration, 4. Oxygen works as a repressor in the synthesis of HIF-1 protein, 5. Both β-galactosidase and HIF-1 are decomposed according to the first order reaction. The effects of hypoxic duration as well as oxygen concentration on the β-galactosidase production were successfully predicated by the model.

Abstract
Analyses of a part of mitochondrial cytochrome c oxidase I gene sequences (645 bp) for seventeen individuals of Epilachna vigintioctopunctata (Fabricius) from eight localities in east and southeast Asia revealed that the populations are divided into two genetically distinct groups (Chiba, Tokyo, Naha, Iriomote, Bangkok vs. Kuala Lumpur, Padang, Bogor). The number of nucleotide substitutions between sequences of different groups was 57-60, while that between sequences within each group was 1-8. Karyotypes of the two groups were also distinctly different. Crossing experiments showed that there exist strong postmating barriers between the two groups: eggs obtained from between-group crossings usually did not hatch, whereas more than 90% of eggs from within-group crossings hatched. It is concluded that E. vigintioctopunctata, a notorious pest of solanaceous crops in Asia and Australia, is composed of at least two reproductively isolated biological species that probably occupy different geographic ranges.

Abstract
Animal cell perfusion high density culture is often adopted for the production of biologicals in industry. In high density culture sometimes the productivity of biologicals has been found to be enhanced. Especially in immobilized animal cell culture, significant increase in the productivity has been reported. We have found that the specific monoclonal antibody (MAb) productivity of an immobilized hybridoma cell is enhanced more than double. Several examples of enhancing productivities have been also shown by collagen immobilized cells. Immobilized cells involve some different points from non-immobilized cells in high density culture: In immobilized culture, some cells are contacted together, resulting in locally much higher cell concentration more than 10(8) cells/ml. Information originating from a cell can be easily transduced to the others in immobilized culture because the distance between cells is much nearer. Here we have performed collagen gel immobilized culture of recombinant BHK cells which produce a human IgG monoclonal antibody in a protein-free medium for more than three months. In this high density culture a stabilized monoclonal antibody production was found with around 8 times higher specific monoclonal antibody productivity compared with that in a batch serum containing culture. No higher MAb productivity was observed using a conditioned medium which was obtained from the high density culture, indicating that no components secreted from the immobilized cells work for enhancing monoclonal antibody production. The MAb productivity by the non-immobilized cells obtained by dissolving collagen using a collagenase gradually decreased and returned to the original level in the batch culture using a fresh medium. This suggests that the direct contact of the cells or a very close distance between the cells has something to do with the enhancement of the MAb productivity, and the higher productivity is kept for a while in each cell after they are drawn apart.

Abstract
AbstractExtensive progress and improvements have been made in the science and technology of gamma titanium aluminide alloys within the last decade. In particular, our understanding of their microstructural characteristics and property/microstructurc relationships has been substantially deepened. Based on these achievements, various engineering two-phase gamma alloys have been developed and their mechanical and chemical properties have been assessed. Aircraft and automotive industries arc pursuing their introduction for various structural components. At the same time, recent basic studies on the mechanical properties of two-phase gamma alloys, in particular with a controlled lamellar structure have provided a considerable amount of fundamental information on the deformation and fracture mechanisms of the two-phase gamma alloys. The results of such basic studies are incorporated in the recent alloy and microstructure design of two-phase gamma alloys. In this paper, such recent advances in the research and development of the two-phase gamma alloys and industrial involvement are summarized.

Abstract
The nitrification of ammonium-rich wastewater is considered challenging due to the substrate inhibition particularly in the form of free ammonia (FA) and free nitrous acid (FNA) in ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB). The feasibility of the nitrifying activated sludge system to completely nitrify synthetic stabilized landfill leachate with N-NH(4)(+) concentration of 1452mg/L was tested in this study. The process started with 0.4kg N-NH(4)(+)/m(3)/day of nitrogen loading rate (NLR) in a fed-batch mode to avoid any accumulation of the FA and FNA in the system followed by increasing the nitrogen loading rate (NLR) gradually. Complete nitrification was achieved with a very high ammonium removal percentage (approximately 100%). The maximum specific and volumetric nitrification rate obtained were 0.49g N-NH(4)(+)/g VSS/day and 3.0kg N-NH(4)(+)/m(3)/day, respectively which were higher than those reported previously for ammonium-rich removal using activated sludge system. The nitrifying sludge exhibited good settling characteristics of up to 36mL/g VSS and a long SRT of more than 53 days which contributed to the success of the nitrification process. The coexistence and syntrophic association of the AOB and NOB was observed by using Fluorescence in situ hybridization (FISH) technique which supported the results on complete nitrification obtained in the system. These findings would be of prominent importance for further treatment of actual sanitary landfill leachate.

Abstract
Since landfilling is the common method of waste disposal in Malaysia, river water is greatly exposed to the risk of contamination from leachate unless proper leachate management is carried out. In this study, leachates from three different types of landfills, namely active uncontrolled, active controlled and closed controlled, were characterized, and their relationships with river water chemistry were examined monthly for a year. The influence of leachate on river water chemistry from each type of landfill depended on many factors, including the presence of a leachate control mechanism, leachate characteristics, precipitation, surface runoff and the applied treatment. The impact of leachate from an active uncontrolled landfill was the highest, as the organic content, NH(4)(+)-N, Cd and Mn levels appeared high in the river. At the same time, influences of leachate were also observed from both types of controlled landfills in the form of inorganic nitrogen (NH(4)(+)-N, NO(3)(-)-N and NO(2)(-)-N) and heavy metals (Fe, Cr, Ni and Mn). Improper treatment practice led to high levels of some contaminants in the stream near the closed controlled landfill. Meanwhile, the active controlled landfill, which was located near the coastline, was exposed to the risk of contamination resulting from the pyrite oxidation of the surrounding area.
