Abstract
Abstract
Background
An incidence of cardiovascular events increases with age in women. The relationship between cardiovascular risk factors, and the underlying pathology and the prevalence of lipid plaques has not been systematically studied in different age groups in women presented with acute coronary syndromes (ACS).
Purpose
We investigated the underlying pathology and the prevalence of lipid plaques in culprit lesions by optical coherence tomography (OCT) in women with different risk factors.
Methods
A total of 382 women who underwent pre-intervention OCT imaging were included. The underlying pathology and the prevalence of lipid plaques in the culprit lesion was compared between women with and without cardiovascular risk factors (i.e. hypertension, smoking, hyperlipidemia, diabetes mellitus, family history and chronic kidney disease) in three different age groups (<60 yr, 60–70 yr, >70 yr).
Results
The relative prevalence of plaque erosion was higher in younger women (<60 yr) and decreased with age (from 51% to 28%, p<0.001). There was no significant difference in the prevalence of lipid plaques between women with and without risk factors, except a higher prevalence of lipid plaques in current smokers compared to non-smokers (79% vs. 63%, p=0.003). In women with hyperlipidemia, the prevalence of lipid plaques was modest in young ages (<60 yr), but increased steeply with age (p<0.001). The increasing age trend for lipid plaque was also observed in women with hypertension (p=0.03) and current smokers (p=0.01). In women with diabetes mellitus and family history, the prevalence of lipid plaques was high even in young ages (<60 yr) and did not increase with age.
Conclusion
The prevalence of plaque erosion was higher in younger women (<60 yr) and decreased with age. Current smokers had significantly higher prevalence of lipid plaque. Patients with diabetes and positive family history had a higher prevalence of lipid plaque at young age. The prevalence of lipid plaques increased with age particularly in women with hyperlipidemia and hypertension.

Abstract
Abstract
Background/Introduction
Healed coronary plaques, morphologically characterized by a layered pattern, are signatures of previous plaque disruption and healing. Recent optical coherence tomography (OCT) studies showed that layered plaque is associated with vascular vulnerability and rapid plaque progression. However, the diagnosis of layered plaque requires expertise in OCT image interpretation and is susceptible to interobserver variability.
Purpose
We aimed to develop a deep learning (DL) model for an accurate diagnosis of layered plaque.
Methods
We developed a Visual Transformer (ViT)-based DL model emulating the cardiologists who review consecutive OCT frames to make a diagnosis (Figure 1), and compared it to the standard convolutional neural network (CNN) model. We used 302,415 cross-sectional OCT images from 873 patients collected from 9 sites: 237,021 images from 581 patients for training and internal validation from 8 sites, and 65394 images from 292 patients collected from another site for external validation.
Results
Model performances were evaluated using the area under the receiver operating characteristics (AUC). In the five-fold cross validation, the ViT-based model showed better performance than the standard CNN-based model with AUC of 0.886 (95% confidence interval [CI], 0.882–0.891) compared with 0.797 (95% CI, 0.790–0.804). The ViT-based model also outperformed the standard CNN-based model in the external validation, with an AUC of 0.857 (95% CI, 0.849–0.864) compared to 0.806 (95% CI, 0.797–0.815) (Figure 2).
Conclusion(s)
The ViT-based DL model will help cardiologists to make an accurate diagnosis of layered plaque, which might help to stratify the risk of future adverse cardiac events.

Abstract
Abstract
Background
Vascular inflammation has been recognized as one of the key factors in the pathogenesis of acute coronary syndromes (ACS). Peri-coronary adipose tissue (PCAT) attenuation by computed tomography angiography (CTA) has emerged as a marker specific for coronary artery inflammation. We examined the relationship between clinical presentation and coronary artery inflammation assessed by PCAT attenuation and coronary plaque characteristics.
Methods
Patients with ACS or stable angina pectoris (SAP) who underwent pre-intervention coronary CTA and optical coherence tomography (OCT) were enrolled. PCAT attenuation was measured around the culprit lesion and in the proximal 40 mm of all coronary arteries. PCAT attenuation and OCT findings were compared between patients with ACS versus SAP.
Results
Among 471 patients (ACS: 198, SAP: 273), PCAT attenuation was higher in ACS patients than in SAP patients both at the culprit plaque level (−67.5±9.6 Hounsfield unit [HU] vs. −71.5±11.0 HU, p<0.001) and the culprit vessel level (−68.3±7.7 HU vs. −71.1±7.9 HU, p<0.001). The mean PCAT attenuation of all 3 coronary arteries was also significantly higher in ACS patients than in SAP patients (−68.8±6.3 HU vs. −70.5±7.1 HU, p=0.007). After adjusting patient characteristics, not only thin-cap fibroatheroma (OR: 2.44; 95% CI: 1.63–3.65) and macrophages (OR: 2.07; 95% CI: 1.34–3.21) but also PCAT attenuation in the culprit plaque (OR: 1.04; 95% CI: 1.02–1.06) was associated with the clinical presentation of ACS.
Conclusions
PCAT attenuation at culprit plaque, culprit vessel, and pan-coronary levels was higher in ACS patients than in SAP patients. Vascular inflammation appears to play a crucial role in the development of ACS.

Abstract
BackgroundThe risk of pregnancy complications, such as gestational hypertension is high in pregnancies with SLE. In addition, the risk of flare is elevated if pregnancy occurs during the high disease activity. The EULAR recommendation provides a checklist for preconception counseling, in which patients with SLE desiring pregnancy were required the condition that the disease activity prior to pregnancy should be stable for 6-12 months in terms of serological activity (1). However, it does not provide specific criteria for serological activity so that physicians should evaluate the risk of pregnancy in each case by their clinical intuitions.ObjectivesIn order to uncover the present clinical situation for the acceptability of pregnancy in patients with SLE, we performed questionnaire survey to physicians regarding to the degree of serological activity.MethodsThis cross-sectional study was performed to physicians registered with the Japanese College of Rheumatology from December 2020 to January 2021 using the online survey. The questionnaire asked about the characteristics of physicians, facilities and the permission of pregnancies with SLE using vignette scenarios. In this study, data from vignettes of women visiting a regular outpatient clinic were used. The vignettes varied in age (28 or 35 years), duration of stable disease and serological activity. Analysis methods were descriptive statistics, chi-square test. generalized estimating equations (GEE) was performed to investigate the relationship between the determining permission for pregnancy and the scenario patient’s characteristics (age, period of stable disease, titer of anti ds-DNA antibody)ResultsThe questionnaire was distributed to 4946 physicians, and 463 responded. Completion rate (ratio agreed to participate/finished survey) of survey was 91.1%. The median age of physicians was 46 (interquartile range (IQR) 2-10). The specialty was rheumatology (84.9%), other internal medicine (8%), and pediatrics (5.6%). There were no significant differences in patient’s age about the acceptability of pregnancy (coeffficianet -0.02, 95% CI -0.17 -0.01, p=0.42). Case who had been stable for 6 months were more tolerant of pregnancy than case who had been stable for 3 months (coeffficianet 0.12, 95% CI 0.09-0.15, P<0.001) Pregnancy was not allowed in case with mild or high serological activity (mild: coefficient -0.49, 95% CI -0.29- -0.22, p <0.001, high: -0.64, 95% CI -0.65 - -0.61, p <0.001). In contrast, as many as 92 (19.2%) physicians tolerated pregnancy even in the presence of residual high anti ds-DNA antibody titers. Female physicians are significantly more cautious about pregnancy than male when patients have a serologically high activity (12% vs 37.5%, p<0.001). There were no significant differences in specialty status or clinical experience.ConclusionWe found that even mild serological activity alone had a significant negative effect on the physician’s decision to allow pregnancy. We conclude that current physicians make cautious decisions about pregnancies of patients with SLE following the recommendation. On the other hand, an additional investigation should be performed about the results of pregnancies in patients with serological abnormalities, since there are some physicians who thought that pregnancy may be acceptable for patients with only serological abnormalities if the clinical symptoms are stable.References[1]Ann Rheum Dis.2017 Mar;76(3):476-485AcknowledgementsI would like to express my gratitude to the members of Japan College of Rheumatology who cooperated in filling out the questionnaire.Disclosure of InterestsSakiko Isojima: None declared, Nobuyuki Yajima: None declared, Ryo Yanai: None declared, Yoko Miura: None declared, Shingo Fukuma: None declared, Kayoko Kaneko: None declared, Keishi Fujio: None declared, Kenji Oku: None declared, Masakazu Matsushita: None declared, Takako Miyamae: None declared, Takashi Wada: None declared, Yuko Kaneko: None declared, Yoshiya Tanaka Speakers bureau: Y.

Abstract
Abstract
Background
The natural progression of coronary calcification has not been systematically studied. In vivo coronary calcium can be evaluated by OCT.
Purpose
To identify the incidence and predictors for rapid progression of coronary calcification.
Methods
Patients with serial OCT imaging at baseline and at 6 months were selected from our database. Changes in calcium index during 6-month follow-up and predictors for progression of calcification were studied. Calcium index was defined as the product of the mean calcium arc and calcium length. Rapid progression of calcification was defined as an increase in calcium index above the median value.
Results
Among 187 patients who had serial OCT imaging, 235 calcified plaques were identified in 108 patients (57.8%) at baseline with median calcium index of 132.0 (Interquartile range 58.5–281.2). After 6 months, the calcium index increased in 95.3% of calcified plaques from 132.0 to 178.2 (p<0.001). In multivariable analysis, diabetes mellitus (DM), chronic kidney disease (CKD), lipid-rich plaque, and macrophages were found to be independent predictors for rapid progression of coronary calcification (table). Interestingly, rapid progression of calcification was associated with a significant reduction of inflammatory features (thin-cap fibroatheroma [TCFA]; baseline 21.2% vs. follow-up 11.9%, p=0.003, macrophages; baseline 74.6% vs. follow-up 61.0%, p=0.001).
Conclusions
This study demonstrated that DM, CKD, lipid-rich plaque, and macrophages were independent predictors for rapid progression of coronary calcification. High level of vascular inflammation may stimulate rapid progression of calcification.

Abstract
Abstract
Background
Two patterns of plaque progression have been described: slow linear progression and rapid step-wise progression. The former will cause stable angina when the narrowing reaches a critical threshold, while the latter may lead to acute coronary syndromes or sudden cardiac death.
Purpose
The aim of the study was to identify morphologic predictors for rapid plaque progression.
Methods
Patients who had OCT imaging during the index procedure and follow-up angiography with a minimum of 6-month interval were selected. Non-culprit lesion was defined as a plaque with a diameter stenosis ≥30% on index angiogram. Lesion progression was defined as the decrease of angiographic minimum lumen diameter ≥0.4 mm at follow-up (mean, 7.1 months). Baseline morphological characteristics of the plaques with rapid progression were evaluated by OCT. In a subgroup with follow-up OCT imaging for plaques with progression, morphological changes from baseline to follow-up were assessed.
Results
Among 517 lesions, 50 lesions showed progression. These lesions had a significantly higher prevalence of lipid-rich plaque (76.0% vs. 50.5%), thin-cap fibroatheroma (TCFA) (20.0% vs. 5.8%), layered plaque (60.0% vs. 34.0%), macrophage accumulation (62.0% vs. 42.4%), microvessel (46.0% vs. 29.1%), plaque rupture (12.0% vs. 4.7%), and thrombus (6.0% vs. 1.1%), compared to those without progression. The multivariable analysis identified lipid-rich plaque [odds ratio (OR) 2.17, 95% confidence interval (CI) 1.02–4.62, p=0.045], TCFA (OR 5.85, 95% CI 2.01–17.03, p=0.001), and layered plaque (OR 2.19, 95% CI 1.03–4.17, p=0.040) as predictors of subsequent lesion progression. In a subgroup with follow-up OCT, a new layer was detected in 14/41 (34.1%) plaques.
Conclusions
Lipid-rich plaque, TCFA, and layered plaque were predictors of subsequent rapid plaque progression. A new layer, a signature of rapid progression through plaque disruption and healing, was detected in 1/3 of the cases.

Abstract
Abstract
Background
Previous studies have reported a circadian variation in the onset of ST-segment elevation myocardial infarction (STEMI). However, underlying mechanisms for the circadian variation have not been fully elucidated.
Purpose
We investigated the relationship between onset of STEMI and the underlying pathology using optical coherence tomography (OCT).
Methods
Patients presenting with STEMI were selected from an international, multi-center, longitudinal registry study, which included patients who underwent OCT imaging of the culprit lesion at 11 institutions in 6 countries. Onset of MI was estimated using the time of OCT imaging. Patients were divided into 4 groups based on the estimated time of onset (00:00–05:59, 06:00–11:59, 12:00–17:59, or 18:00–23:59). Underlying pathologies of MI (plaque rupture, plaque erosion, and calcified plaque) were compared among the 4 groups.
Results
Among 648 patients, plaque rupture was diagnosed in 386 patients (59.6%), plaque erosion in 197 patients (30.4%), and calcified plaque in 65 patients (10.0%). A marked circadian variation was detected in the incidence of plaque rupture with a peak at 9:00, whereas it was not evident in plaque erosion or calcified plaque. The probability of plaque rupture increased in the periods of 06:00–11:59 (odds ratio: 2.13, 95% confidence interval: 1.30 to 3.49, p=0.002) and 12:00–17:59 (odds ratio: 2.10, 95% confidence interval: 1.23 to 3.58, p=0.005), compared to the period of 00:00–05:59. This circadian pattern was observed only during weekdays (p=0.013) and it was not evident during the weekend (p=0.742).
Conclusions
Plaque rupture occurred most frequently in the morning and the circadian variation was evident only during the weekdays. Acute MI caused by plaque rupture may be related to catecholamine surge.

Abstract
Background:Rheumatoid Arthritis (RA) is common in women with reproductive age. For this reason, RA treatment during pregnancy and lactation is very important. In recent years, the use of biologic disease-modifying antirheumatic drugs (bDMARDs) has become common in RA treatment (1), treatment during pregnancy and lactation has changed drastically (2,3).Objectives:To investigate the pregnancy, delivery and lactation status of RA patients and treatment during that period in daily practice.Methods:The IORRA cohort is a large, single institute-based, observational cohort of RA patients established at Institute of Rheumatology, Tokyo Women’s Medical University, in 2000. We identified female RA patients aged 20-49 years who answered ‘pregnant’ or ‘delivered’ in the IORRA survey in 2010-2016 and whose pregnancies were confirmed in the medical records. We examined the Disease Activity Score with 28 joint count (DAS28)-CRP, medication use situation, the outcome of pregnancy, and lactation in those patients.Results:A total of 101 patients and 143 pregnancies were confirmed, of which 136 outcomes of pregnancy could be confirmed in the medical records. Among 136 confirmed pregnancy cases, there were 106 births and 30 miscarriages. Among 106 births, 4 cases (3.8%) were birth defects that could be confirmed in the medical records. The average age at pregnancy was 34.2±3.7 years and 36.1±3.3 years in delivered and miscarried cases, respectively. Miscarried cases were significantly older pregnancies (p=0.01). Of the 106 births, 65 birth weeks were confirmed, with an average of 37.9±1.8 weeks. The number of preterm delivery was 11 cases (16.9%). The average birth weight of 59 babies whose birth weight could be confirmed was 2699±517 g. There were 21 cases (35.6%) of low birth weight infants. The proportion of patients in DAS28-CRP remission was 73.1% before pregnancy, 61.6% during pregnancy, and 68.0% 1 year after delivery. Drugs used before pregnancy were glucocorticoid (48.8%), non-steroidal anti-inflammatory drugs (14.2%), conventional synthetic DMARDs (24.8%), and bDMARDs (48.0%). Etanercept accounted for 90% of bDMARDs. Among taking bDMARDs patients, 73.8% were discontinued after the pregnancy, and 26.2% were continued during pregnancy. Among those patients who continued bDMARDs, lactating patients were 12/26 (46.2%) cases after delivery, 10/30 (33.3%) cases in six months after delivery, and 7/36 (19.4%) cases in 1 year after delivery, respectively.Conclusion:The actual situation of pregnancy, delivery, and lactation in RA patients was revealed. Especially, bDMARDs were used at relatively high rates in RA patients who wish to have a child.References:[1]Lancet. 2017;10;389:2338-2348.[2]Semin Arthritis Rheum. 2019;49:S32-S35.[3]Rheumatology. 2016;55:1693-7.Disclosure of Interests:Moeko Ochiai: None declared, Eiichi Tanaka Consultant of: ET has received lecture fees or consulting fees from Abbvie, Asahi Kasei pharma co., Bristol Myers Squibb, Chugai Pharmaceutical, Daiichi Sankyo Co., Eisai Pharmaceutical, Janssen Pharmaceutical K.K., Nippon Kayaku, Pfizer, Takeda Pharmaceutical, Taisho Toyama Pharmaceutical Co., and UCB Pharma., Speakers bureau: ET has received lecture fees or consulting fees from Abbvie, Asahi Kasei pharma co., Bristol Myers Squibb, Chugai Pharmaceutical, Daiichi Sankyo Co., Eisai Pharmaceutical, Janssen Pharmaceutical K.K., Nippon Kayaku, Pfizer, Takeda Pharmaceutical, Taisho Toyama Pharmaceutical Co., and UCB Pharma., Eisuke Inoue Speakers bureau: EI has received speaker fee from Bristol-Meyers, Pfizer, Merck serono., Mai Abe: None declared, Eri Sugano: None declared, Naohiro Sugitani: None declared, Kumiko Saka: None declared, higuchi yoko: None declared, Rei Yamaguchi: None declared, Naoki Sugimoto: None declared, Ikari Katsunori Speakers bureau: KI has received speaker’s fee from Asahi Kasei Pharma Corp., Astellas Pharma Inc., AbbVie Japan GK, Ayumi Pharmaceutical Co., Bristol Myers Squibb Co., Ltd., Chugai Pharmaceutical Co., Ltd., Eis, ai Co., Ltd., Eli Lilly Japan K.K., Janssen Pharmaceutical K.K., Kaken Pharmaceutical Co.

Abstract
Background:It has been reported that female rheumatoid arthritis (RA) patients have a longer time to pregnancy than healthy women (1), and that high Disease Activity Score with 28 joint count (DAS28) -CRP in preconception increases the frequency of infertility (2). Before the era of biologics, RA treatment tended to be inadequate from pregnancy planning to the end of lactation. And it was not uncommon for female RA patients to be unable to get pregnant or develop physical dysfunction as a result of insufficient control of the disease. There are some reports of disease activity during pregnancy and postpartum in RA patients, and the effects of RA disease activity on pregnancy and childbirth outcomes (3-5), but there are few reports focusing on the physical function during pregnancy planning of RA patients.Objectives:To investigate disease activity and physical function in female patients with RA who planned and didn’t plan pregnancy.Methods:The IORRA cohort is a large, single institute-based, observational cohort of RA patients established at the Institute of Rheumatology, Tokyo Women’s Medical University, in 2000. We identified female RA patients aged 20-49 years who answered ‘pregnant’ or ‘delivered’ in the IORRA survey in 2010-2015 and whose pregnancy and the pregnancy planning time was confirmed in the medical records, and defined them as the pregnancy planning (PP) group. Matched control was extracted at 1:3 ratio from patients without pregnancy plan based on entry time, age, RA disease duration, DAS28-CRP, Japanese version of Health Assessment Questionnaire (J-HAQ) score, and comorbidities. The primary endpoint was J-HAQ at 3years from the baseline, which was defined as the most recent IORRA survey before planning pregnancy. The mixed-effect model for repeated measures was used to analyze group difference.Results:There were 40 patients in the PP group (average 32.2 years, disease duration 5.7 years, DAS28-CRP 1.7, J-HAQ 0.26), and 120 patients in the control group (average 32.4 years, disease duration 5.9 years, DAS28-CRP 1.7, J-HAQ 0.21). The proportion of user and dosage of MTX and glucocorticoid (GC) and bDMARDs user at baseline were comparable between the groups (MTX: PP 87.5% [9.8 mg/week], control 85.0% [8.8 mg/week]; GC: PP 32.5% [3.6 mg/day], control 27.5% [4.4 mg/day]; bDMARDs: PP 40.0%, control 27.5%). DAS28-CRP at year 3 of the PP group elevated and was higher than the control group (PP 2.3, control 1.7, p<0.01), while J-HAQ was stable over the observation period and did not differ significantly at year 3 (PP 0.21, control 0.22, p=0.92). At year 3, the proportion of patients taking MTX was lower and taking GC was higher in the PP group than those in the control group (MTX: PP 36.7%, control 76.7%, p<0.01; GC: PP 70.0%, control 25.6%, p<0.01). The proportion of patients taking bDMARDs was not different in both groups (PP 36.7%, control 32.6%, p=0.68).Conclusion:Physical function in pregnancy planning patients with RA did not deteriorate as well as the control patients in clinical settings.References:[1]Arthritis Rheum. 2011;63:1517-1521.[2]Ann Rheum Dis. 2015;10:1836-1841.[3]J Rheumatol. 2015;42:1376-1382.[4]J Rheumatol. 2019;46:245-250.[5]Arthritis Care Res. 2017;69:1297-1303.Disclosure of Interests:Moeko Ochiai: None declared, Eiichi Tanaka Consultant of: ET has received lecture fees or consulting fees from Abbvie, Asahi Kasei pharma co., Bristol Myers Squibb, Chugai Pharmaceutical, Daiichi Sankyo Co., Eisai Pharmaceutical, Janssen Pharmaceutical K.K., Nippon Kayaku, Pfizer, Takeda Pharmaceutical, Taisho Toyama Pharmaceutical Co., and UCB Pharma., Speakers bureau: ET has received lecture fees or consulting fees from Abbvie, Asahi Kasei pharma co., Bristol Myers Squibb, Chugai Pharmaceutical, Daiichi Sankyo Co., Eisai Pharmaceutical, Janssen Pharmaceutical K.K., Nippon Kayaku, Pfizer, Takeda Pharmaceutical, Taisho Toyama Pharmaceutical Co., and UCB Pharma., Eisuke Inoue Speakers bureau: EI has received speaker fee from Bristol-Meyers, Pfizer, Merck serono., Mai Abe: None declared, Eri Sugano: None declared, Naohiro Sugitani: None declared, Kumiko Saka: None declared, higuchi yoko: None declared, Rei Yamaguchi: None declared, Naoki Sugimoto: None declared, Ikari Katsunori Speakers bureau: KI has received speaker’s fee from Asahi Kasei Pharma Corp., Astellas Pharma Inc., AbbVie Japan GK, Ayumi Pharmaceutical Co., Bristol Myers Squibb Co., Ltd., Chugai Pharmaceutical Co., Ltd., Eis, ai Co., Ltd., Eli Lilly Japan K.K., Janssen Pharmaceutical K.K., Kaken Pharmaceutical Co.

Abstract
Background:Patients with antiphospholipid antibody (aPL) are said to be at increased risk for thrombosis, however it is difficult to predict whether they will develop thrombosis. In recent years, it has been revealed that the characteristics of the second derivative curve of APTT waveform with aPL positive patient is biphasic changes1,2. As first step in predicting the risk of thrombosis, we sought to understand the effect of aPL on APTT waveform patterns.Objectives:To analyze the characteristics of APTT waveforms according to the background diseases and the presence of aPLMethods:Patients who underwent coagulation function tests from 2017 to 2019 were analyzed. A coagulation waveform (Clot waveform: CW) was drawn using a fully automatic coagulation time measuring device manufactured by Instrumentation Laboratory From the APTT waveform, the 1st derivative curve (DC) indicating the coagulation speed and the 2nd DC indicating the coagulation acceleration were depicted to measure the 1st DC height, 2nd DC peak 1 time, and 2nd DC peak 1 height (Figure12). Patients were devided into CTD with aPL-negative patients (group A), aPL-positive patients with no prior thrombosis (group B), and antiphospholipid antibody syndrome (APS) (group C). Patients characteristics and aPL (anti-cardiolipin [CL] antibody IgM, anti-CL antibody IgG, anti-CLβ2GP1 complex antibody, LA-APTT, and LA- DRVVT) status were examind. A further analysis was performed according to the numbers of positive aPL. Comparison between the three groups were made by the one-way ANOVA method, with significant differences set as p-values <0.1. Factors with significant differences were analyzed by Steel-Dwass test. APTT waveforms was analyzed according to the numbers of positive aPL by least squares methods. Furthermore, to determine the cut off value of APTT, 1st DC height, 2nd DC peak 1 time, and 2nd DC peak 1 height for each case with 2 or more positive aPLs and 3 positive aPLs, area under the curve (AUC) of the receiver operating characteristic (ROC) curve, sensitivity and specificity were caliculated.Figure 1.Results:The APTT waveform was analyzed in 61 patients (51 women, 83.6%) with average age of 54.1 ± 17.1 years. Group A was 26 cases, Group B was 18 cases, and Group C was 17 cases. APTT, 2nd DC peak1 time, 2nd DC peak1 height, 1st DC peak time were significantly different among A, B, and C groups (p <0.01). APTT, 1st DC peak height, 2nd DC peak 1 time, and 2nd DC peak 1 height differed among the number of aPL (p < 0.01, respectively). APTT and 2nd DC peak1 time prolonged by 9.43 (seconds) and 16.3 (seconds) respectively according to the number of aPLs increased, and 1st DC peak height (mabs/s) and 2nd DC peak1 height (mabs/s2) decreased by 56.4 (mabs/s) and 223.9 (mabs/s2) respectively according to the number of aPLs decreased (Table 1). APTT> 35.2 (seconds) (sensitivity 80%, specificity 80.4%), 2nd DC peak1 height> 302 (mabs/s2) (sensitivity 80%, specificity 91.3%) were relevant to the presence of two or more aPLs and APTT> 35.2 (seconds) (sensitivity 100%, specificity 80%), 2nd DC peak1 height> 302 (mabs/s2) (sensitivity 100%, specificity 90%) were relevant to the presence of three aPLs.Table 1.The number of positive aPL0123p valueThe number of cases2719411APTT(seconds)28.9[26.8, 31.4]30.9[29.1, 38.2]31.1[27.3, 54.2]60.7[45.9, 73.7]0.00012nd DC peak time (seconds)29.2[26.8, 30.7]33.7[31, 41.7]36.1[31.5, 99]75.8[50.5, 102.4]0.00012nd DC peak height (mabs/s2)839.9[666.1, 962.2]669.6[346.4, 946]608.4[137.8, 956.7]119.3[30.6, 196]0.00011st DC peak height (mabs/s)309.6[260.6, 355.1]271.5[168, 353]241.8[96.3, 364.0]135.6[76.8, 163]0.0001Conclusion:The presence of aPL was more related to the 2nd DC peak1 height of APTT waveform than APTT.

Abstract
Background:The mortality of patients with rheumatoid arthritis (RA) had been reported as being worse than that of the general population [1, 2], but is expected to have improved over time because the progress in treatment of RA during the past twenty years has been actively adopted to RA management [3, 4]. However, the change in the mortality still remains controversial in patients with early RA [5, 6].Objectives:To investigate whether the vital prognosis of patients with early RA has changed in the past twenty years.Methods:The IORRA cohort is a large observational cohort established in 2000 at the Institute of Rheumatology, Tokyo Women’s Medical University. Essentially, all Japanese patients diagnosed with RA at our institute were registered and clinical parameters were assessed biannually. As there is no National Death Registry in Japan, we obtained death report from residual families who responded to our mail query to patients who failed to conduct the subsequent IORRA survey, from physicians of affiliated hospitals and from police in case they found dead patient outside of a hospital. In this study, the patients with early RA (less than 2 years of disease duration) who participated in the survey for the first time from 2001 to 2012 were included and observed for five years from the date of the initial survey. We classified patients into group A (enrolled in 2001-2006) and B (enrolled in 2007-2012). Five-year survival rate and standardized mortality ratio (SMR) were calculated for each group. SMR was calculated using the life tables in Japanese general population reported by the Ministry of Health, Labour and Welfare, Japan. The effects of loss to follow-up cases were evaluated by multiple imputation method as a sensitivity analysis of SMR.Results:A total of 3,217 patients with early RA were analyzed. The number of patients was 1,609 (79.4% female) in the group A and 1,608 (81.8% female) in B. The median age at baseline was 55 in both groups. Among a total of 3,217 patients, 486 (15.1%) patients were lost during 5-year follow-up; 213 (13.2%) in the group A and 273 (17.0%) in B, respectively. During the observational period, deaths were confirmed in 47 cases (2.9%) in the group A and 45 (2.8%) in B. Major causes of death included malignancies (28% in the group A, 38% in B), respiratory involvement (23% in the group A, 40% in B), cerebrovascular disorders (11% in the group A, 2% in B), and cardiovascular disorders (11% in the group A, 0% in B). The five-year survival rate was 88.8% for the group A and 87.8% for B, and the SMR was 0.81 (95%CI: 0.59-1.08) for the group A and 0.78 (0.57-1.04) for B when assuming all the lost to follow-up patients were alive for 5 years. In the sensitivity analysis assuming that the mortality rate of patients who were lost to follow-up was twice as that of the general population, the SMR was 0.90 (0.68-1.19) for the group A and 0.92 (0.68-1.23) for B.Conclusion:The mortality of patients with early RA in the past twenty years has been comparable to that of the Japanese general population. In addition, the SMR and the five-year survival rate did not change overtime.References:[1]Cobb, S., et al. N Engl J Med 1953; 249(14): 553-556.[2]Nakajima, A., et al.

Abstract
Background:Patients with elderly-onset rheumatoid arthritis (EORA) are on the rise in the aging or super-aging society, especially in Japan. Patients with EORA have more comorbidities than those with younger-onset RA, a higher risk of adverse drug reactions due to reduced drug metabolism, and a higher risk of infections1). Therefore, patients with EORA tend to receive suboptimal treatment, resulting in insufficient control of disease activity2). Although several studies reported treatment responsiveness in patients with EORA, many of them have a limited observation period3-8), and long-term treatment responses and their associated factors need to be clarified.Objectives:We retrospectively evaluated treatment responses of patients with EORA for 3 years and their associated factors in a clinical setting.Methods:The Institute of Rheumatology Rheumatoid Arthritis (IORRA) cohort is a large, single institute-based, observational cohort of RA patients established at Institute of Rheumatology, Tokyo Women’s Medical University, in 2000. The subjects were RA patients who first enrolled in the IORRA cohort from 2010 to 2014, were over 60 years old with less than 1-year disease duration, and had a DAS28-ESR over 3.2 at entry. The primary endpoint was DAS28-ESR <3.2 after 3-year observation. A multivariate logistic regression analysis was conducted to identify factors at baseline associated with the primary endpoint. The missing values of DAS28-ESR were imputed by using the last observation carried forward method.Results:Among a total of 250 patients in this study, 152 patients (60.8%) achieved DAS28-ESR <3.2 after 3-year observation (remission/low disease activity (RL) group), and 98 patients did not (moderate/high disease activity (MH) group). Baseline characteristics of the patients were as follows (average ± SD or %): the RL group, age 69.9 ± 6.5, female 77%, DAS28-ESR 4.3 ± 0.8, J-HAQ 0.9 ± 0.7, PSL user 23.7%, MTX user 64.5%, and biologics user 4.0%; the MH group, age 69.4 ± 6.7, female 80.6%, DAS28-ESR 4.4 ± 0.8, J-HAQ 1.0 ± 0.7, PSL user 36.7%, MTX user 64.3%, and biologics user 6.1%. Proportions of the patients with cardiovascular disease and malignancy were 13.3% and 11.2% in the MH group and 5.9% and 1.3% in the RL group, respectively. DAS28-ESR and J-HAQ score after 3-year observation of the RL group were 2.3±0.5 and 0.4±0.5, respectively, and those of the MH group were 3.4±0.9 and 1.0±0.8, respectively. Corticosteroid use and having malignancy at baseline were associated with not achieving DAS28-ESR <3.2 after 3-year observation using multivariate analysis (Table 1). Similar results were obtained when MTX use and corticosteroid use were replaced by the average dose of each drug.Conclusion:The majority of the patients with EORA achieved DAS28-ESR <3.2 after 3-year observation, and no use of corticosteroid and absence of malignancy at baseline were associated with the good outcome.References:[1]Nat Rev Rheumatol 2013;9:604-613[2]Ann Rheum Dis 2006;65:1226-1229[3]Ann Rheum Dis 2009;68:1470–1473[4]Joint Bone Spine 2015;82:25-30[5]J Rheumatol 2016;43:1974-1983[6]Rheumatology 2015;54:798-807[7]Rheumatology 2014;53:1075-1086[8]Japanese Journal of Geriatrics 2018;55:251-258Acknowledgments:We thank all patients who participated in the IORRA survey and all of the members of the Institute of Rheumatology, Tokyo Women’s Medical University, for the successful management of the IORRA cohort.Disclosure of Interests:Mai Abe: None declared, Eiichi Tanaka Consultant of: Abbvie, Asahi Kasei pharma co., Bristol Myers Squibb, Chugai Pharmaceutical, Daiichi Sankyo Co., Eisai Pharmaceutical, Janssen Pharmaceutical K.K., Nippon Kayaku, Pfizer, Takeda Pharmaceutical, Taisho Toyama Pharmaceutical Co., and UCB Pharma., Eisuke Inoue Speakers bureau: EI has received speaker fee from Bristol-Meyers, Pfizer, Merck serono., Eri Sugano: None declared, Naohiro Sugitani: None declared, Kumiko Saka: None declared, Moeko Ochiai: None declared, Yoko Shimizu: None declared, Rei Yamaguchi: None declared, Naoki Sugimoto: None declared, Katsunori Ikari Speakers bureau: Asahi Kasei Pharma Corp., Astellas Pharma Inc., AbbVie Japan GK, Ayumi Pharmaceutical Co., Bristol Myers Squibb Co., Ltd., Chugai Pharmaceutical Co., Ltd., Eis, ai Co., Ltd., Eli Lilly Japan K.K., Janssen Pharmaceutical K.K., Kaken Pharmaceutical Co.

Abstract
Abstract
Objectives
We assessed clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main (ULM) using current generation drug eluting stents (cDES) in hemodialysis (HD) patients compared to general populations.
Methods
We identified 1269 consecutive patients who underwent PCI for ULM distal bifurcation lesions. Of them, 563 patients were treated with cDES (512 non HD and 51 HD patients). The primary endpoint was target lesion failure (TLF) at 3 years, defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI).
Results
HD group was more likely to have diabetes mellitus (70.0% vs. 45.8%, p=0.002), peripheral artery disease (56.0% vs. 14.9%, p<0.001), and lower ejection fraction (52.6% vs. 56.3%, p=0.026). The rate of TLF at 3 years was significantly higher in the HD group (adjusted Hazard ratio [HR] 2.59; 95% confidence interval [CI], 1.54–4.37; p<0.001). Cardiac mortality was significantly higher in the HD group (adjusted HR 4.49; 95% CI, 2.07–9.74; p<0.001). The rates of TLR for LM-left anterior descending artery (LAD) and left circumflex ostium (LCXos) were significantly higher in the HD group (LMT-LAD: adjusted HR 3.10; 95% CI, 1.31–7.33; p=0.01, LCXos: adjusted HR 2.56; 95% CI, 1.32–4.94; p=0.005). The rate of MI was similar between the 2 groups.
Conclusions
Hemodialysis was strongly associated with adverse events after PCI for ULM distal bifurcation lesions even with cDES.

Abstract
BACKGROUND Clinical testing to determine a suitable dose of linaclotide for Japanese patients with irritable bowel syndrome with constipation (IBS-C) was needed. METHODS This was a randomized, double-blind, placebo-controlled, dose-finding trial. Japanese patients with IBS-C diagnosed using Rome III criteria (n = 559, men/women: 49/510) were randomly assigned to 1 of 4 linaclotide doses (0.0625, 0.125, 0.25, or 0.5 mg) or placebo for the 12-week treatment period. The primary endpoint was responder rate of global assessment of relief of IBS symptoms during 12 weeks. The secondary endpoints included responder rates of complete spontaneous bowel movement (CSBM), SBM and abdominal pain/discomfort relief and others. KEY RESULTS The primary endpoint was 23.2%, 36.2%, 38.7%, 34.8%, and 38.3% in placebo (n = 112), 0.0625 (n = 116), 0.125 (n = 111), 0.25 (n = 112), and 0.5 (n = 107) mg of linaclotide groups with the difference from the placebo group in each linaclotide group (13.0%, 15.5%, 11.6%, 15.1%, P > .05). Monthly responder rate of global assessment of relief of IBS symptoms at month 3 (48.6%), responder rate of CSBM during 12 weeks (45.8%), and responder rate of abdominal pain/discomfort relief during 12 weeks (32.7%) in the 0.5 mg were significantly higher than those in placebo group (29.5%, P < .01; 25.9%, P < .01; and 18.8%, P < .05 respectively). The most frequent adverse event in the linaclotide groups was diarrhea. CONCLUSIONS & INFERENCES This study suggests that a linaclotide dose of 0.5 mg may be appropriate in Japanese patients with IBS-C.

Abstract
BACKGROUND The Gut and Obesity Asia (GO ASIA) workgroup was formed to study the relationships between obesity and gastrointestinal diseases in the Asia Pacific region. AIM To study factors associated with nonalcoholic steatohepatitis (NASH) and advanced fibrosis, and medical treatment of biopsy-proven nonalcoholic fatty liver disease (NAFLD) patients. METHODS Retrospective study of biopsy-proven NAFLD patients from centres in the GO ASIA Workgroup. Independent factors associated with NASH and with advanced fibrosis on binary logistic regression analyses in a training cohort were used for the development of their corresponding risk score, which were validated in a validation cohort. RESULTS We included 1008 patients from nine centres across eight countries (NASH 62.9%, advanced fibrosis 17.2%). Independent predictors of NASH were body mass index ≥30 kg/m2 , diabetes mellitus, dyslipidaemia, alanine aminotransferase ≥88 U/L and aspartate aminotransferase ≥38 U/L, constituting the Asia Pacific NASH risk score. A high score has a positive predictive value of 80%-83% for NASH. Independent predictors of advanced fibrosis were age ≥55 years, diabetes mellitus and platelet count <150 × 109 /L, constituting the Asia-Pacific NAFLD advanced fibrosis risk score. A low score has a negative predictive value of 95%-96% for advanced fibrosis. Only 1.7% of patients were referred for structured lifestyle program, 4.2% were on vitamin E, and 2.4% were on pioglitazone. CONCLUSIONS More severe liver disease can be suspected or ruled out based on factors identified in this study. Utilisation of structured lifestyle program, vitamin E and pioglitazone was limited despite this being a cohort of biopsy-proven NAFLD patients with majority of patients having NASH.

Abstract
BACKGROUNDS Chronic intestinal pseudo-obstruction (CIPO) is an intractable rare digestive disease manifesting persistent small bowel distension without any mechanical cause. Intestinal decompression is a key treatment, but conventional method including a trans-nasal small intestinal tube is invasive and painful. Therefore, a less invasive and tolerable new decompression method is urgently desired. We conducted a pilot study and assessed the efficacy and safety of percutaneous endoscopic gastro-jejunostomy (PEG-J) decompression therapy in CIPO patients. METHODS Seven definitive CIPO patients (2 males and 5 females) were enrolled. All patients received PEG-J decompression therapy. The number of days with any abdominal symptoms in a month (NODASIM), body mass index (BMI), serum albumin level (Alb), and small intestinal volume before and after PEG-J were compared in all patients. RESULTS Percutaneous endoscopic gastro-jejunostomy was well tolerated and oral intake improved in all patients. NODASIM has significantly decreased (24.3 vs 9.3 days/months) and BMI/Alb have significantly increased (14.9 vs 17.2 kg/m2 and 2.6 vs 3.8 g/dL, respectively), whereas total volume of the small intestine has not significantly reduced (4.05 vs 2.59 L, P=.18). Reflux esophagitis and chemical dermatitis were observed in one case but was successfully treated conservatively. CONCLUSIONS & INFERENCES Percutaneous endoscopic gastro-jejunostomy decompression therapy can contribute greatly to improvement of abdominal symptoms and nutritional status in CIPO patients. Although sufficient attention should be paid to acid reflux symptoms, PEG-J has the potential to be a non-invasive novel decompression therapy for CIPO available at home. However, accumulation of more CIPO patients and long-term observation are needed (UMIN000017574).

Controlling joint instability delays the degeneration of articular cartilage in a rat model. Osteoarthritis Cartilage 2017; 25:297-308.

Abstract
OBJECTIVE Joint instability induced by anterior cruciate ligament (ACL) transection is commonly considered as a predisposing factor for osteoarthritis (OA) of the knee; however, the influence of re-stabilization on the protection of articular cartilage is unclear. The aim of this study was to evaluate the effect of joint re-stabilization on articular cartilage using an instability and re-stabilization ACL transection model. DESIGN To induce different models of joint instability, our laboratory created a controlled abnormal joint movement (CAJM) group and an anterior cruciate ligament transection group (ACL-T). Seventy-five Wistar male rats were randomly assigned to the CAJM (n = 30), ACL-T (n = 30), or no treatment (INTACT) group (n = 15). Cartilage changes were assessed with soft X-ray analysis, histological and immunohistochemistry analysis, and real-time polymerase chain reaction (PCR) analysis at 2, 4, and 12 weeks. RESULTS Joint instability, as indicated by the difference in anterior displacement between the CAJM and ACL-T groups (P < 0.001), and cartilage degeneration, as evaluated according to the Osteoarthritis Research Society International (OARSI) score, were significantly higher in the ACL-T group than the CAJM group at 12 weeks (P < 0.001). Moreover, joint re-stabilization maintained cartilage structure (thickness [P < 0.001], surface roughness [P < 0.001], and glycosaminoglycan stainability [P < 0.001]) and suppressed tumor necrosis factor-alpha (TNF-α) and caspase-3 at 4 weeks after surgery. CONCLUSION Re-stabilization of joint instability may suppress inflammatory cytokines, thereby delaying the progression of OA. Joint instability is a substantial contributor to cartilage degeneration.

Abstract
Studies of chemotactic cell migration rely heavily on various assay systems designed to evaluate the ability of cells to move in response to attractant molecules. In particular, the development of microfluidics-based devices in recent years has made it possible to spatially distribute attractant molecules in graded profiles that are sufficiently stable and precise to test theoretical predictions regarding the accuracy and efficiency of chemotaxis and the underlying mechanism of stimulus perception. However, because the gradient is fixed in a direction orthogonal to the laminar flow and thus the chamber geometry, conventional devices are limited for the study of cell re-orientation to gradients that move or change directions. Here, we describe the development of a simple radially symmetric microfluidics device that can deliver laminar flow in 360°. A stimulant introduced either from the central inlet or by photo uncaging is focused into the laminar flow in a direction determined by the relative rate of regulated flow from multiple side channels. Schemes for flow regulation and an extended duplexed device were designed to generate and move gradients in desired orientations and speed, and then tested to steer cell migration of Dictyostelium and neutrophil-like HL60 cells. The device provided a high degree of freedom in the positioning and orientation of attractant gradients, and thus may serve as a versatile platform for studying cell migration, re-orientation, and steering.

Abstract
BACKGROUND The association of diverticula with bowel habits is unclear. We therefore analyzed the association between diverticula and bowel habits in over 1000 Japanese individuals. METHODS Japanese subjects who underwent total colonoscopies at seven centers in Japan from June to September 2013 were analyzed. Bowel habits were evaluated using the Gastrointestinal Symptom Rating Scale, and stool form was assessed using a part of the Bristol Scale and Rome ΙΙΙ criteria. Diverticula were diagnosed by colonoscopy with a transparent soft-short hood. KEY RESULTS The study evaluated 1066 subjects, 648 males and 418 females (ratio, 1.55 : 1), of mean age 63.9 ± 13.0 years. After adjusting for age and sex, the presence of constipation was associated with a significantly reduced likelihood of diverticula (odds ratio [OR] = 0.70, 95% confidence interval [CI] 0.52-0.93). When assessed according to the location of diverticula, the presence of constipation was associated with a significantly decreased likelihood of left-sided (OR = 0.39, 95% CI 0.16-0.93), but not right-sided (OR = 1.10, 95% CI 0.48-2.53), diverticula. Furthermore, stool form was unrelated with the presence or absence of diverticula. CONCLUSIONS & INFERENCES The wide-spread hypothesis that constipation was associated with colonic diverticula was not supported. Rather, we found that the absence of diverticula was associated with constipation, suggesting the need to reassess the etiology of colonic diverticula.

Abstract
BACKGROUND The clinical benefits of conversion chemotherapy followed by liver resection for initially unresectable colorectal liver metastases are still controversial. The criteria for unresectability vary from one team to another. To clarify this issue, we retrospectively assessed the survival and characteristics of metastatic colorectal cancer (mCRC) patients with liver-limited disease (LLD) who underwent conversion therapy. METHOD Our criteria for resectability depended on the size of the remnant liver volume (>30 %) and expected function after removal of all metastases. Between December 2007 and September 2011, a total of 115 patients were diagnosed as having mCRC with LLD and received chemotherapy. Among them, 47 had tumors that were initially diagnosed as resectable. They underwent hepatic resection after chemotherapy (resected group). Of the 67 tumors were initially diagnosed as unresectable, 12 became resectable after chemotherapy (conversion group), leaving 55 tumors that remained unresectable after chemotherapy (unresected group). RESULTS The median follow-up was 25.2 months. Hepatic resection was more invasive in the conversion group than in the resected group. Median disease-free survival was significantly higher in the resected group than in the conversion group (p = 0.013). Overall survival (OS) was also higher in the resected group, but the difference was not significant (p = 0.36). However, OS was significantly higher in the conversion group than in the unresected group (p = 0.034). Multivariate analysis of the resected and conversion groups showed that OS was significantly negatively influenced by abnormal carcinoembryonic antigen levels at surgery (p = 0.037) and a hospital stay >30 days (p = 0.009). CONCLUSIONS Our results showed that conversion chemotherapy could contribute to longer OS in mCRC patients with LLD.

Histopathologic findings in patients with idiopathic megacolon: a comparison between dilated and non-dilated loops. Neurogastroenterol Motil 2014; 26:571-80.

Abstract
BACKGROUND Idiopathic megacolon (IMC) is an intractable motility disorder in which chronic symptoms of colonic dysmotility appear with no mechanical cause. Although a pathological analysis is essential to understand the mechanism of IMC, no study has compared the histopathologic findings between dilated and non-dilated loops in IMC cases, and little is known about the proportion of each disease subtype. METHODS Fifty-three full-thickness samples (dilated loops, n = 31; non-dilated loops, n = 22) from 31 IMC cases and 16 samples (dilated loops; n = 8, non-dilated loops; n = 8) from eight controls were collected. All the samples were stained with hematoxylin-eosin (HE), Hu C/D antibody, and CD117 antibody to assess degenerative myopathy, degenerative neuropathy, inflammatory neuropathy, hypoganglionosis, and mesenchymopathy according to the London Classification. Findings of the dilated and non-dilated loop samples were compared, and the proportions of each subtype were analyzed. KEY RESULTS Based on a control study, <60 ganglion cells/cm was defined as hypoganglionosis in our series. Myopathy was observed in 11 patients (35.5%), neuropathy was in 19 patients (61.3%), and mesenchymopathy was in 10 patients (32.2%). An overlap between subtypes was observed in some cases. Surprisingly, the non-dilated loop samples exhibited very similar histopathologic abnormalities to those observed in the dilated loop samples in most cases. CONCLUSIONS & INFERENCES Our study is the first to compare the histopathologic findings between dilated and non-dilated loops in IMC patients. Histopathologic abnormalities precede the clinical manifestation of IMC, and may consequently lead to gradual colonic dilatation; however, detailed mechanism including dilation triggering factor needs further elucidation.

Abstract
Abstract There has recently been an increased understanding of the role of costimulatory pathways in the activation of the immune system and the maintenance of self-tolerance. It has been suggested that the absence of costimulatory molecules on normal tissue cells could serve to induce self-tolerance, and that inappropriate expression of costimulatory molecules on antigen-presenting cells (APCs) could activate self-reactive T cells, resulting in autoimmunity. Among several costimulatory molecules characterized, the interaction of CD28/CTLA4 on T cells with B7 (CD80 and CD86) on APC appears to be of primary importance. In fact, inhibition of the CD28-B7 interaction ameliorates several autoimmune diseases in experimental animal models. However, differential roles for CD80 and CD86 have been reported in certain conditions, and CTLA4 has been shown to play a negative role in T cell activation, suggesting that the actual regulatory mechanisms of this pathway in autoimmunity is much more complex. While the CD28-B7 interaction constitutes a predominant pathway of T cell costimulation, some intact T cell responses in CD28-deficient mice have suggested the presence of alternative pathways. T cell-dependent immunity is also critically regulated not only by other immunoglobulin superfamilies such as B7RP-1/ICOS, but also by tumor necrosis factor (TNF) and TNF-receptor superfamilies, which control immune responses in both a positive and a negative fashion. Therefore, further investigation of the physiological function of these costimulatory pathways in vivo may help in developing rational therapeutic approaches for autoimmune diseases.
