Abstract
UNLABELLED This study revealed the change in the paravertebral muscles in patients with osteoporotic vertebral fracture. Increased pain is likely to be the driver for reduced activity, reduced activities of daily living, and consequent increase in fat infiltration of the paravertebral muscles, assumed to be secondary to reduced activity level or, conversely, partial immobilization. INTRODUCTION To reveal the time courses and impact of the paravertebral muscles (PVMs) on the healing process of osteoporotic vertebral fractures and risk factors for PVM decrease. METHODS Consecutive patients with symptomatic osteoporotic vertebral fractures were enrolled in 11 hospitals. At enrollment and 3- and 6-month follow-up, PVMs, including the multifidus and erector spinae, were examined using magnetic resonance imaging (MRI). The PVM cross-sectional area (CSA) and fat signal fraction (FSF) were measured at L3. Low back pain (LBP), activities of daily living (ADLs), and risk factors for PVM decrease at the 6-month follow-up were investigated. PVM decrease was defined as > 1 standard deviation decrease of the CSA or > 1 standard deviation increase of the FSF. RESULTS Among 153 patients who completed the 6-month follow-up, 117 (92 women, 79%) had MRI of L3 at enrollment and 3- and 6-month follow-up (mean age at enrollment, 78.5 years). The CSA did not change 6 months from onset (p for trend = 0.634), whereas the FSF significantly increased (p for trend = 0.033). PVM decrease was observed in 30 patients (26%). LBP was more severe, and delayed union was more frequent in patients with PVM decrease (p = 0.021 mixed-effect model and p = 0.029 chi-square test, respectively). The risk factors for PVM decrease were ADL decline at the 3-month follow-up (adjusted odds ratio = 5.35, p = 0.026). CONCLUSION PVM decrease was significantly related to LBP and delayed union after osteoporotic vertebral fracture onset. ADL decline at the 3-month follow-up was a risk factor for PVM decrease. Therefore, restoring ADLs within 3 months after onset is important.

Abstract
Background:MTX is transported into cells and retained long after polyglutamation. MTXPG level can predict response and possibly adverse effects of MTX. We reported erythrocyte MTXPG concentrations efficiently discriminated patients with and without hepatotoxicity1. We also developed genetic and clinical prediction models for efficacy and hepatotoxicity of MTX2. In the present study, we firstly investigated the effects of clinical and secondly genetic variables on the concentration of total MTXPG and determined oral maximum MTX dose without hepatotoxicity using these variables.Objectives:To develop a prediction model for maximum MTX dose without hepatotoxicity.Methods:Concentrations of erythrocyte MTX-PG (PG1 to PG4) were detected by LC-MS/MS and calculated total MTXPG as sum of them. MTX-PGn levels were measured in 265 RA patients including 40 patients with elevated AST or ALT (≥ 60 U/L; 1.5 times of upper limits) and the 6 SNPs of 6 gens related to MTXPG metabolism were identified by RT-PCR.Results:Total concentrations of MTXPG were 141.3 ± 86.5 and 87.6 ± 47.8 nmol/L (mean±SD) in 40 RA patients with hepatotoxicity and 225 patients without, respectively (p<0.0001). By ROC analysis, the two groups were most efficiently discriminated with cutoff concentration of 100.0 nmol/L (AUC 0.731). Next, genetic and clinical model to speculate the MTXPG concentration was established by multivariate analysis using 4 clinical and 3 genetic variables which were selected from 20 clinical and 6 genetic variables by univariate analysis (p<0.1). Finally, a speculation model for MTXPG concentration by 4 clinical variables (MTX dose, BMI, RBC count, and creatinine) and one genetic variable (GGH c.452C>T) was developed (Figure). When MTXPG concentration of 100 nmol/L was applied to the model, maximum MTX dose without hepatotoxicity was calculated for each patient asMTX dose (mg) = {100 (MTXPG) – 96 + 1.7*BMI + 28*RBC - 120*creatinine - 19.3*GGH(C/T)} / 7.7. Real dose of oral MTX exceeded the calculated dose in 23 of 40 patients (57.5%) with hepatotoxicity, whereas it exceeded in 95 of 223 patients (42.6%) without hepatotoxicity (OR 1.82, p=0.081).Conclusion:Maximum MTX dose without hepatotoxicity was speculated by several clinical and genetic markers without measurement of erythrocyte MTX-PG concentrations.References:[1]Takahashi M, et al: Clinical Pathology (Rinsho Byori), 67:433-442, 2019.[2]Onishi A, et al: The Pharmacogenomics J, doi.org/10.1038/s41397-019-0134-9, 2019Disclosure of Interests:Shunichi Kumagai Grant/research support from: Astellas, Chugai, Mitsubishi Tanabe Co.Ltds, Consultant of: Sysmex Co.Ltd, Speakers bureau: many companies, Soshi Takahashi: None declared, Miho Takahashi: None declared, Toshiharu Saito: None declared, Katsuyuki Yoshida: None declared, Motoko Katayama: None declared, Saki Mukohara: None declared, Norihiko Amano: None declared, Akira Onishi Speakers bureau: AO received a speaker fee from Chugai, Ono Pharmaceutical, Eli Lilly, Mitsubishi-Tanabe, Asahi-Kasei, and Takeda, Masakazu Shinohara: None declared, Saori Hatachi: None declared

Abstract
Background:Immunometabolism is now recognaized to be crucial in the pathogenesis of rheumatoid arthritis (RA). We have recently shown that the expression of glutaminase 1 (GLS1), a key enzyme in glutaminolysis, is upregulated in fibroblast-like synoviocytes from RA patients (RA-FLS) and that GLS1 inhibition suppresses RA-FLS proliferation (1). However, glutaminolysis has been known to suppress autophagy by activating mTORC1 or counteracting ROS production (2). Given the possibility of autophagy upregulation following glutamiolysis inhibition, therapies targeting both autophagy and glutaminolysis may be more effective in suppressing cell growth of RA-FLS, yet the relation between glutaminolysis and autophagy in RA-FLS has not been investigated.Objectives:To examine the effects of inhibiting both glutaminolysis and autophagy on RA-FLS and autoimmune arthritis in SKG mice.Methods:GLS1 inhibitor, compound 968 (C968), was used to suppress glutaminolysis, and Chloroquine (CQ) was used to inhibit autophagy. To detect autophagy, the expression of ATG5 and LC3B was measured by real-time PCR and the production of LC3-II was analyzed by Western blotting. The formation of autophagic vacuoles was identified by immunfluorescense. Cell growth was evaluated by BrdU assay. Apoptosis was analyzed by flow cytometry staining with Annexin V-FITC and PI. C968 and CQ were administered subcutaneously to Zymosan A-injected SKG mice.Results:C968 upregulated the expression of ATG5 and LC3B, and increased the protein level of LC3-II in RA-FLS. C968 also facilitated autophagosome formation. These results suggested that inhibition of glutaminolysis promoted autophagy in RA-FLS. The combined treatment with C968 and CQ significantly suppressed cell proliferation of RA-FLS more strongly than did C968 or CQ alone. In addition, C968 combined with CQ increased the apoptosis rate, whereas either C968 or CQ alone did not. Furthermore, combination of C968 and CQ significantly attenuated the degree of arthritis in SKG mice, while C968 or CQ monotherapy did not (Figure).Conclusion:The GLS1 inhibitor C968 promotes autophagy in RA-FLS. C968 in combination with CQ reduces proliferation and enhances apoptosis in RA-FLS, and ameliorates the arthritis in SKG mice. Suppressing C968-induced autophagy may be a promising therapy for arthritis.References:[1] Takahashi S., et al. Arthritis Res Ther. 2017 Apr 11;19(1):76.[2] Villar VH., et al.

Abstract
Background:Though several studies showed the efficacy of tacrolimus (TAC) in patients with rheumatoid arthritis (RA) in a dose-depending manner [1], the relationship between efficacy and concentration of TAC remained unclear. Genetic polymorphisms of cytochrome P450 (CYP) 3A5 were reported not only to play an important role in pharmacokinetics of TAC but also to have an influence on clinical outcomes in patients of rheumatic diseases. Several reports showed that the blood concentration of TAC in patients with a CYP3A5 *1 allele (EX, expressor) was lower than that of patients with a CYP3A5 *3/*3 (NEX, non-expressor) [2].Objectives:To assess the relationship between efficacy and concentration of TAC in patients with RA, and to examine the usefulness of CYP3A5 genotype screening to detect outpatients suitable for TAC treatment.Methods:We examined the relationship between disease activity score (DAS) 28-CRP and concentration of TAC in patients with RA. TAC was taken after the evening meal and blood samples were taken 12±4h after TAC administration. Next we investigated the relationship between genotype frequencies of CYP3A5 and concentration of TAC in patients with rheumatic disease without having renal dysfunction (eGFR<60) and also investigated the influence of concomitant drugs, such as strong inhibitors of CYP3A4/5 or metabolized by CYP3A4/5, to C/D value in each NEX and EX group. The blood concentration of TAC normalized to the corresponding dose per body weight (C/D, ng/ml per mg/kg) was analyzed according to genetic variation in CYP3A5. Furthermore we investigated the relationship between genotype frequencies of CYP3A5 and concentration of TAC in patients with rheumatic disease at first visit and second visit after starting TAC administration to assess the possibility for making rapid attainment of enough concentrations of TAC in early stage of treatment.Results:The concentration of TAC tended to be negatively correlated with the disease activity of RA. The C/D value in the NEX group (n=16) was 124.7±62.1, which was significantly higher than that in the EX group (n=23; 67.7±29.8;P<0.001). When comparing patients using concomitant drugs which are strong inhibitors of CYP3A4/5 or metabolized by CYP3A4/5 with patients not using those drugs, the each C/D value of NEX group was 122.9±52.3 (n=9) and 126.9±77.3 (n=7), and that of EX group was 71.3±32.2 (n=12) and 63.8±28.0 (n=11). There were no significant differences between these groups. In NEX group, when comparing concentration of TAC at first visit and second visit after starting TAC administration, the each concentration of TAC was 3.14±2.06 ng/ml and 3.80±2.20 ng/ml in NEX group (n=10), and that of TAC was 1.82±0.82 ng/ml and 2.69±1.52 ng/ml (n=11) in EX group (Figure).Conclusion:TAC showed efficacy in patients with RA in a concentration-dependent manner. EX patients may be impossible to achieve enough concentration of TAC even though using TAC of 3mg/day, approved dose for patients with RA in Japan, and NEX patients could make rapid attainment of enough concentrations of TAC in early stage of treatment, suggesting that we should consider induction of TAC only in NEX outpatients. Furthermore, drugs only slightly affected concentration of TAC in this study, suggesting that we can use TAC without any special attention to concomitant drugs.References:[1]Furst DE et al.

Abstract
Background:Tacrolimus (TAC), an immunosuppressant, can be used in second-line maintenance therapy of interstitial lung disease (ILD) in patients with dermatomyositis (DM) [1]. In Japan, TAC is approved for DM-ILD and often used as induction therapy for severe cases, especially in patients with anti-MDA5-Ab (melanoma differentiation-associated gene 5 antibody) positive, in combination with glucocorticoids (GC) and intravenous cyclophosphamide (IVCY). Some studies reported the clinical efficacy of initial high-trough level TAC for DM-ILD in combination with GC and IVCY [2]. Adjustment to target concentration of TAC in early stage of treatment is important for controlling disease activity. The concentration of TAC depends on genetic polymorphisms in cytochrome P450 (CYP) 3A5 enzyme expression and several reports showed that the bioavailability and concentration of TAC in patients with a CYP3A5 *1 allele (*1) was lower than those with a CYP3A5 *3/*3 (*3/*3) [3].Objectives:To examine the usefulness of CYP3A5 polymorphisms in decision of initial dose to achieve the target concentration of TAC and to evaluate the clinical efficacy in patients of DM-ILD who achieved the enough concentration of TAC in early stage of treatment.Methods:We investigated CYP3A5 polymorphisms and TAC concentration in 9 patients of DM-ILD without renal dysfunction (eGFR>60). TAC was taken after both morning and evening meals and blood samples were taken 12h after TAC administration. The blood concentration of TAC normalized to the corresponding dose per body weight (C/D, ng/ml per mg/kg) was analyzed according to genetic variation in CYP3A5. Based on the retrospective analyzation, we chose proper dose of TAC in initial treatment for an anti-MDA5-Ab positive DM-ILD patient, whose genotype was *3/*3.Results:The C/D value in the *3/*3 group (n=6) was 154.6±25.6, which was significantly higher than that in the *1 group (n=3;79.0±2.8; P =0.028). When the target concentration was set at 5-10 ng/ml, the required dose was (0.0316 to 0.0633) mg/kg in the *1 group and (0.0162 to 0.0324) mg/kg in the *3/*3 group. The *1 group needs more dose than that of the *3/*3 group to achieve the same target trough of TAC, suggesting that the examination of CYP3A5 genotype is useful for deciding initial dose of TAC (Fig.1). We started TAC 6mg/day with setting target concentration at 15-20 ng/ml to a *3/*3 patient of DM-ILD with anti-MDA5-Ab positive, resulting in good clinical course with making rapid attainment of target concentration in early stage of treatment (Fig.2).Conclusion:To examine the CYP3A5 genotype is valuable for deciding the initial dose of TAC, especially in patients who need achievement to target concentration rapidly.References:[1]Oddis CV and Aggarwal R.

Abstract
BACKGROUND A recently published Position Statement (PS) by the Preimplantation Genetics Diagnosis International Society (PGDIS) regarding utilization of preimplantation genetic testing for aneuploidy (PGT-A) in association with in vitro fertilization (IVF) contained inaccuracies and misrepresentations. Because opinions issued by the PGDIS have since 2016 determined worldwide IVF practice, corrections appear of importance. METHODS The International Do No Harm Group in IVF (IDNHG-IVF) is a spontaneously coalesced body of international investigators, concerned with increasing utilization of add-ons to IVF. It is responsible for the presented consensus statement, which as a final document was reached after review of the pertinent literature and again revised after the recent publication of the STAR trial and related commentaries. RESULTS In contrast to the PGDIA-PS, we recommend restrictions to the increasing, and by IVF centers now often even mandated, utilization of PGT-A in IVF cycles. While PGT-A has been proposed as a tool for achieving enhanced singleton livebirth outcomes through embryo selection, continued false-positive rates and increasing evidence for embryonic self-correction downstream from the testing stage, has led IDNHG-IVF to conclude that currently available data are insufficient to impose overreaching recommendations for PGT-A utilization. DISCUSSION Here presented consensus offers an alternative to the 2019 PGDIS position statement regarding utilization of preimplantation genetic testing for aneuploidy (PGT-A) in association with in vitro fertilization (IVF). Mindful of what appears to offer best outcomes for patients, and in full consideration of patient autonomy, here presented opinion is based on best available evidence, with the goal of improving safety and efficacy of IVF and minimizing wastage of embryos with potential for healthy births. CONCLUSIONS As the PGDIS never suggested restrictions on clinical utilization of PGT-A in IVF, here presented rebuttal represents an act of self-regulation by parts of the IVF community in attempts to control increasing utilization of different unproven recent add-ons to IVF.

Abstract
After many decades of vaccination, measles epidemiology varies greatly between and within countries. National immunization programs are therefore encouraged to conduct regular situation analyses and to leverage models to adapt interventions to local needs. Here, we review applications of models to develop locally tailored interventions to support control and elimination efforts. In general, statistical and semi-mechanistic transmission models can be used to synthesize information from vaccination coverage, measles incidence, demographic, and/or serological data, offering a means to estimate the spatial and age-specific distribution of measles susceptibility. These estimates complete the picture provided by vaccination coverage alone, by accounting for natural immunity. Dynamic transmission models can then be used to evaluate the relative impact of candidate interventions for measles control and elimination and the expected future epidemiology. In most countries, models predict substantial numbers of susceptible individuals outside the age range of routine vaccination, which affects outbreak risk and necessitates additional intervention to achieve elimination. More effective use of models to inform both vaccination program planning and evaluation requires the development of training to enhance broader understanding of models and where feasible, building capacity for modelling in-country, pipelines for rapid evaluation of model predictions using surveillance data, and clear protocols for incorporating model results into decision-making.

Abstract
AIM This is a cross-sectional study of relation between metabolic syndrome and cognitive function in community-dwelling non-demented older adults in Japan. We examine the effect of metabolic syndrome and its components on global cognitive function. We also aim to clarify differences of specific cognitive domains between the subjects with and without metabolic syndrome. METHODS We studied 2150 subjects aged between 60 and 90 years whose scores on mini mental state examination (MMSE) were over 23 points. We analyzed difference in MMSE scores between the subjects with and without metabolic syndrome. Logistic regression analysis was performed with MMSE score as the dependent variable and metabolic syndrome components as the independent variable adjusted with age. We also examined differences in attention, logical memory, and verbal and category fluency between the subjects with and without metabolic syndrome. RESULTS MMSE scores were not significantly different between subjects with and without metabolic syndrome. In logistic regression analysis, the score of MMSE was significantly negatively associated with triglycerides in males and significantly negatively associated with abdominal circumference in females. Subjects with metabolic syndrome showed significantly lower performance of attention tasks compared to subjects without metabolic syndrome. CONCLUSIONS Our results suggest that in community-dwelling non-demented Japanese older adults, attention but not global cognitive function may be impaired by metabolic syndrome. Inverted association between some components of metabolic syndrome and global cognitive function indicate necessity of further studies on the relation between undernutrition and cognitive function.

Abstract
Methotrexate (MTX)-induced intestinal mucosal injury in animals has been studied to understand how MTX can cause gastrointestinal disorders, but the pathogenesis of gastrointestinal disorders is still uncertain. We have attempted to reveal how dietary factors influence intestinal toxicity due to MTX. Mice were fed normal chow (NC) or a high-fat high-sucrose diet (HFHSD) before oral administration of MTX. While MTX significantly decreased the survival rates of mice fed HFHSD, the intestinal epithelial injury was detected. MTX excretion in the feces of mice fed HFHSD was reduced. Change of diets between NC and HFHSD influences the survival. The survival rates of the mice fed a high-sucrose diet or control diet were higher than those fed HFHSD. Higher survival rates were observed in mice fed a high-fat high-sucrose diet modified (HFHSD-M) in which casein was replaced by soybean-derived proteins. The survival rates of mice treated with vancomycin were lower than those administered neomycin. Microbiome and metabolome analyses on feces suggest a similarity of the intestinal environments of mice fed NC and HFHSD-M. HFHSD may modify MTX-induced toxicity in intestinal epithelia on account of an altered MTX distribution as a result of change in the intestinal environment.

Abstract
Abstract
Background
Cholesterol crystals (CCs) have been recognized as only ghost images. Recently, free monolayer and multilayer CCs besides atheromatous materials from aortic ruptured plaque, obtained using nonobstructive angioscopy, were demonstrated using polarized light microscopy.
Purpose
The aim of the study was to detect free CCs from coronary slow flow.
Methods
A total of 86 patients with coronary artery disease underwent angioscopy with coronary artery sampling. Blood in the coronary artery with and without temporary slow flow was sampled. The blood sample was spread onto a filter paper, and the filter paper was rinsed with distilled water (filter paper-rinse method). The rinse water was scanned using polarized light microscopy, and CCs were detected. The dimensions of CCs from the coronary artery and aortic ruptured plaques were measured for 100 randomly selected samples. The lengths and widths of the CCs were measured.
Results
CCs were obtained in 31 of 86 patients (36.0%). CCs were detected in 38.4% of patients with acute coronary syndrome and in 31.9% of patients with stable angina. CCs were detected 47.1% with slow flow and in 25% without slow flow.
Cholesterol Crystals in Coronary Artery
Conclusions
CCs from the coronary artery can be successfully obtained by using our original method. CCs were detected in patients with clinically stable angina and in those without coronary artery slow flow.

Abstract
Abstract
Background
In recent years it has been attempted to use a distal radial artery (DRA) as a puncture site for cardiac catheterization and intervention. A patency of radial artery is important in hemodialysis patients because the radial artery is source as an arteriovenous shunt. However, the incidence of radial artery occlusion (RAO) is not known after DRA puncture.
Purpose
To compare RAO rates after DRA puncture between dialysis and non-dialysis patients.
Method
This was retrospective, observational and single center study. All consecutive 1,533 patients undergoing DRA puncture were analyzed. The primary endpoint is RAO rates. The secondary endpoint is composite bleeding adverse event rates. These endpoints were evaluated by a vascular echocardiography several hours or the next day after the procedure.
Result
Among 1,533 patients, 26 were dialysis patients and 1,504 were non-dialysis patients. 1,386 people (90.5%) succeeded in puncture. Radial artery occlusion occurred in 7 patients (0.4%), all of whom were non-dialysis patients. There was no significant difference of RAO rate in dialysis patients and non-dialysis patients.
Conclusion
When performing DRA puncture, the probability of radial artery occlusion is not higher in dialysis patients than non-dialysis patients. The DRA puncture may be one of the option as puncture site even in dialysis patients.

Abstract
Abstract
Background
Non-obstructive general angioscopy has enabled to demonstrate high incidence of various types of spontaneous ruptured aortic plaques/injuries (SRAPIs).
Purpose
The aim of the study is to clarify the relationship between SRAPI and cardiovascular risk factors.
Methods
A total of 439 consecutive patients who had or suspected coronary artery disease were performed angioscopy and were screened SRAPI from ascending aorta to iliac artery. The incidence and the number of SRAPI were analyzed. Association between the total number of total SRAP and patients' characteristics were analyzed.
Results
The total number of SRAPI detected was 2211, 10 [4,22](median [IQR]) per patient.
The numbers of high incidence of representative SRAPI, such as erosion, intramural bleeding, puff-chandelier rupture, puff rupture, fissure, flap, bleeding from fissure, and subintimal bleeding were 327, 313, 268, 262, 224, 167, 120, and 91, respectively. Stepwise multiple linear regression analysis indicated that age, smoking, HbA1c, and coronary heart disease significantly affected the numbers of overall SRAPI (Table).
Conclusions
SRAPIs were associated with cardiovascular risk factors.
