Abstract
Background
Inflammatory status pre-percutaneous coronary intervention (PCI) and post-PCI has been reported not only associated with poor prognosis, but also to impair renal function. Statins reduce cardiovascular events by lowering lipids and have anti-inflammatory impacts, but residual inflammatory risk (RIR) exists. It remains unclear that the synergistic effect of RIR and chronic kidney disease (CKD) on long-term clinical outcome in stable coronary artery disease (CAD) patients undergoing PCI in statin era.
Aim
The aim of this study was to investigate the long-term combined impact of RIR evaluating hs-CRP at follow-up and CKD among stable CAD patients undergoing PCI in statin era.
Methods
This is a single-center, observational, retrospective cohort study assessing consecutive 2,984 stable CAD patients who underwent first PCI from 2000 to 2016. We analyzed 2,087 patients for whom hs-CRP at follow-up (6–9 months later) was available. High residual inflammatory risk was defined as hs-CRP >0.6 mg/L according to the median value at follow up. Patients were assigned to four groups as Group1 (high RIR and CKD), Group2 (low RIR and CKD), Group3 (high RIR and non-CKD) or Group4 (low RIR and non-CKD). We evaluated all-cause death and major adverse cardiac events (MACE), defined as a composite of cardiovascular (CV) death, non-fatal myocardial infarction (MI) and non-fatal stroke.
Results
Of patients (83% men; mean age 67 years), there were 299 (14.3%) patients in group 1, 201 (9.6%) patients in group 2, 754 (36.1%) patients in group 3, and 833 (39.9%) patients in group 4. The median follow-up period was 5.2 years (IQR, 1.9–9.9 years). In total, 189 (frequency, 16.1%) cases of all-cause death and 128 (11.2%) MACE were identified during follow-up, including 53 (4.6%) CV deaths, 27 (2.4%) MIs and 52 (4.8%) strokes. The rate of all-cause death and MACE in group 1 was significantly higher than other groups (p<0.001, respectively). There was a stepwise increase in the incidence rates of all-cause death and MACE. After adjustment for important covariates, the presence of high RIR and/or CKD were independently associated with higher incidence of MACE and higher all-cause mortality. (shown on figure).
Conclusion
The presence of both high RIR and CKD conferred a synergistic adverse effect on the risk for long-term adverse cardiac events in patients undergoing PCI.

Abstract
Background The role of antithrombotic chemoprophylaxis in prevention of venous thromboembolism (VTE) in laparoscopic surgery for gastric and colorectal malignancies is unknown. This study compared the addition of enoxaparin following intermittent pneumatic compression (IPC) with IPC alone in patients undergoing laparoscopic surgery for gastrointestinal malignancy. Methods In this multicentre RCT, eligible patients were older than 40 years and had a WHO performance status of 0 or 1. Exclusion criteria were prescription of antiplatelet or anticoagulant drugs and history of VTE. Patients were allocated to IPC or to ICP with enoxaparin in a 1 : 1 ratio. Stratification factors included sex, location of cancer, age 61 years and over, and institution. Enoxaparin was administered on days 1–7 after surgery. Primary outcome was VTE, evaluated by multidetector CT on day 7. Results Of 448 patients randomized, 208 in the IPC group and 182 in the IPC with enoxaparin group were evaluated. VTE occurred in ten patients (4·8 per cent) in the IPC group and six (3·3 per cent) in the IPC with enoxaparin group (P = 0·453). Proximal deep vein thrombosis and/or pulmonary embolism occurred in seven patients (3·4 per cent) in the IPC group and one patient (0·5 per cent) in the IPC with enoxaparin group (P = 0·050). All VTE events were asymptomatic and non‐fatal. Bleeding occurred in 11 of 202 patients in the IPC with enoxaparin group, and one patient needed a transfusion. All bleeding events were managed by discontinuation of the drug. Conclusion IPC with enoxaparin after laparoscopic surgery for gastric and colorectal malignancies did not reduce the rate of VTE.

Abstract
Background:Balicitinib (BAR) is one of the Janus kinase (JAK) inhibitors, which mainly inhibits JAK1 and JAK2 and has an anti-inflammatory effect on rheumatoid arthritis(RA). In Japan, it is necessary to use different doses of BAR depending on the RA patient’s estimated glomerular filtration rate (eGFR). The RA-BEACOM and RA-BUILD trials reported the treatment effects by BAR dose at 24 weeks and concluded that there was no difference in DAS(disease activity score)28CRP between BAR 2mg and 4mg. The patient background treated in these double-blind RCTs is uniform even at different BAR doses.There is uncertainty about the difference in the therapeutic effects of BAR dose under the real clinical setting where the patient background differs from that of the trial patients.Objectives:To compare patient backgrounds and treatment outcome by Baricitinib dose under real clinical setting.Methods:113 RA patients taking BAR who were registered in the Nagoya University Orthopedic Surgery Multicenter Study (TBCR) were included in this study. Patient characteristics (such as age, illness duration, combined anti-rheumatic drugs, eGFR) and DAS28CRP, clinical and simplified disease activity index(CDAI, SDAI respectively) up to 24 weeks were compared between BAR 2mg and 4mg groups. The continuation rates, including the discontinuation due to ineffectiveness and adverse events (AEs), were also compared between the two groups. For these comparisons, Student’s t-test and Pearson’s chi-square test, Kaplan-Meier survival curve were used. Missing data due to discontinuation of BAR was complemented by LOCF method and analyzed statistically. The significance level was set to less than 0.05.Results:There were 39 subjects (8 males and 31 females) in BAR2mg group and 74 patients (17 males and 57 females) in BAR4mg group. There was a significant difference in mean age (73.5 vs. 62.3 years old,p<0.001), average eGFR (65.1vs 84.8ml / min / 1.73m2,p<0.001), methotrexete(MTX) use rate (28 vs 58%,p<0.01), average MTX dose (3.0 vs 5.5mg,p<0.01),glucocorticoid(GC) use rate(51.3 vs 33.8%,p<0.01) between the two groups(Table). DAS28CRP improved from week 0 (3.2 vs 3.5) to week 24 (2.5 vs 2.4), and no significant difference was observed between the two groups at each time point (Fig.1-A). The same was true for CDAI and SDAI(Fig.1-B,-C). The rate of DAS28CRP remission and low disease activity was not significantly different at 24 weeks (0.64 vs. 0.69, Fig.1-D). The same was true for CDAI and SDAI(Fig.1-E,-F). Kaplan-Meier analysis showed that there was no difference in discontinuation rate due to ineffectiveness in the two groups. The same was true for the discontinuation rate due to AEs (Figure 2-B,-C). The total continuation rate including discontinuation due to ineffectiveness and AEs was significantly lower in BAR2mg group (0.691 vs 0.843,p<0.05, Fig.2-A).Conclusion:BAR2mg group under real clinical setting was older and had lower eGFR than BAR4mg group. Although the treatment effect for 24 weeks was similar, safety management was considered more important because the discontinuation rate due to AEs tended to be higher in BAR2mg group.References:[1]Taylor PC, (2017) The New England journal of medicine. 376(7), 652.[2]Takeuchi T, Ann Rheum Dis 2019;78:171–178.[3]Keystone EC, Ann Rheum Dis 2015;74:333–340Table 1.ITT outcomes at week 13BAR2mg (n=39)BAR4mg (n=74)pvalueAge, years old73.5±9.762.3±12.6<0.001Female31(79)57(77)0.767Disease duration, year13.7±11.314.2±15.40.857Stage(1/2/3/4)6/17/8/815/24/14/210.473ACPA >4.5U/ml29(74.4)59(79.7)0.629eGFR, ml/min/1.73m265.1±27.784.8±23.2<0.001MTX dose, mg/week3.03±4.835.54±5.480.018MTX use11(28.2)41(55.4)0.003GC dose, mg/day1.91±2.361.32±2.200.191GC use20(51.3)25(33.8)0.007DAS28CRP3.42±1.043.52±13.00.689CDAI12.6±7.615.1±10.90.222SDAI14.7±9.716.2±11.40.279Values are the mean±SD or the number (%).Disclosure of Interests:Tsuyoshi Nishiume: None declared, Nobunori Takahashi Speakers bureau: AbbVie, Asahi Kasei, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eisai, Eli Lilly, Janssen, Mitsubishi Tanabe, Ono, Pfizer, Takeda, and UCB Japan, Toshihisa Kojima Grant/research support from: Chugai, Eli Lilly, Astellas, Abbvie, and Novartis, Consultant of: AbbVie, Speakers bureau: AbbVie, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eli Lilly, Janssen, Mitsubishi Tanabe, Pfizer, and Takeda, Shuji Asai Speakers bureau: AbbVie, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eisai, Janssen, Takeda, and UCB Japan, Kenya Terabe: None declared, Naoki Ishiguro Grant/research support from: AbbVie, Asahi Kasei, Astellas, Chugai, Daiichi-Sankyo, Eisai, Kaken, Mitsubishi Tanabe, Otsuka, Pfizer, Takeda, and Zimmer Biomet, Consultant of: Ono, Speakers bureau: Astellas, Bristol-Myers Squibb, Daiichi-Sankyo, Eli Lilly, Pfizer, and Taisho Toyama

Abstract
Background:The clinical effectiveness of abatacept (ABA) in rheumatoid arthritis (RA) patients has been reported to be higher when the patients’ anti-cyclic citrullinated peptide antibody (ACPA) status is positive. The report from the ORA registry demonstrated that the ACPA positivity was associated with a better response to ABA [1]. In a sub-analysis of the AMPLE trial, patients with very high ACPA titers who were treated with ABA had a statistically significant response compared to patients with lower titers [2]. However, these studies did not demonstrate the data regarding the structural progression.Objectives:This study aimed to evaluate the effectiveness of ABA on the clinical disease activity as well as the radiographic progression in patients with RA in the clinical settings.Methods:All eligible patients were registered in the TBCR, a Japanese multicenter registry system for RA patients treated with biologics [3]. The present study included 553 consecutive patients whose ACPA data were obtained, treated with ABA and observed for longer than 52 weeks. We primarily compared the status of disease activity (SDAI) and radiographic progression (van der Heijde modified total Sharp score: mTSS) between ACPA-positive [ACPA (+)] and ACPA-negative [ACPA (-)] RA patients. The ACPA positive was defined as ≥13.5 U/ml of anti-CCP antibody.Results:Number of cases was 446/ 107 [ACPA (+)/ ACPA (-)], respectively. Baseline characteristics between groups were quite similar; mean age was 68.0/ 67.3 years, rate of methotrexate (MTX) use rate was 41.2/ 50.0%, rate of bio-naive was 28.0/ 31.8%, and mean SDAI score was 22.2/ 20.8. Significant difference was observed in mean change in SDAI score from baseline to 52 weeks between the ACPA (+) and ACPA (-) group (-13.4 vs -9.9, p = 0.027) (Figure 1A). Proportion of patents that achieved low disease activity (LDA; SDAI ≤11) at 52 weeks was significantly higher in the ACPA (+) group compared to the ACPA (-) group (72.1 vs 56.0%, p < 0.01) (Figure 1B). In univariate and multivariate logistic regression analysis, ACPA positivity was an independent predictor for achievement of LDA at 52 weeks (Table). There observed no significant difference between ACPA (+) and ACPA (-) group in the proportion of patients that achieved structural remission (ΔmTSS ≤0.5) at 52 weeks (66.2 vs 62.1%) (Figure 2A) as well as mean change in mTSS (1.66 vs 1.17), erosion score (0.60 vs 0.53), and joint narrowing (JSN) score (1.06 vs 0.64) (Figure 2B).Table.UnivariateMultivariateVariablesOR (95%CI)p-valueadjusted OR (95%CI)p-valueAge0.99 (0.98-1.01)0.4391.00 (0.97-1.02)0.749male (vs female)1.12 (0.70-1.80)0.6340.79 (0.40-1.58)0.511disease duration0.99 (0.97-1.00)0.0530.99 (0.97-1.01)0.468Biologics-naïve1.23 (0.81-1.85)0.3351.18 (0.67-2.08)0.575Concomitant MTX use1.12 (0.75-1.69)0.5851.14 (0.66-1.95)0.649Concomitant PSL use0.82 (0.55-1.23)0.3290.97 (0.58-1.64)0.923SDAI @baseline0.96 (0.94-0.97)<0.0010.96 (0.94-0.98)<0.001mHAQ @baseline0.50 (0.36-0.69)<0.0010.57 (0.38-0.86)0.008ACPA positive2.03 (1.29-3.17)0.0022.61 (1.36-5.00)0.004Bold italic, p<0.05Conclusion:Consistent with previous reports, the ACPA-positive group demonstrated significantly higher LDA achievement rate at 52 weeks and indeed the ACPA positivity was significantly associated with LDA achievement in multivariate analysis. However, the ACPA-negative group demonstrated quite similar transition of SDAI score and LDA achievement rate except at 52 weeks compared with the ACPA-positive group. Additionally, there was no significant difference in the structural progression at 52 weeks between the groups. ABA treatment may be considered not only in the ACPA-positive RA patients but also in the ACPA-negative patients in the clinical practice.References:[1]Gottenberg JE, et al.

Abstract
Background:New medications including biologics and aggressive treatment strategies can halt the inflammatory and destructive disease processes in patients with rheumatoid arthritis (RA), and in some cases repair damaged joints. In the process of damaged joint repair, periarticular osteophyte formation might be detected radiographically (1). However, little is known about the clinical and functional role of osteophyte formation in RA joints. Total joint arthroplasty, a common procedure for treating damaged large joints, can serve as a surrogate for the long-term outcome of large joint destruction in patients with RA.Objectives:To determine the influence of periarticular osteophyte formation on the incidence of total knee arthroplasty (TKA) in patients with RA.Methods:This retrospective longitudinal study used data from a registry of patients with RA starting biologics. A flow chart summarizing the study design is shown in Figure 1. A total of 130 symptomatic (tender and/or swollen) knee joints in 80 patients were studied with a median follow-up of 12 years. All data were analyzed using the knee joint as the statistical unit of analysis. The cumulative incidences of TKA were estimated using Kaplan-Meier curves, and compared according to the presence or absence of osteophyte on plain anteroposterior radiograph [osteophyte (+/-)] and the extent of advanced joint damage as defined by Larsen’s grading system (0-II vs. III-V).Results:Baseline characteristics of all subjects included in this study are shown in Table 1. A total of 42 knees underwent TKA during the follow-up period. There was no significant difference in the cumulative incidence of TKA between the osteophyte (+) and osteophyte (-) groups (31% vs. 34% at 10 years, P=0.718) (Fig. 2A). The cumulative incidence of TKA was significantly higher for the Larsen grade III-V group compared to the Larsen grade 0-II group (56% vs. 10% at 10 years, P<0.001) (Fig. 2B). While no significant difference was observed in the cumulative incidence of TKA between the osteophyte (+) and osteophyte (-) groups in the Larsen grade 0-II group (9% vs. 10% at 10 years, P=0.774) (Fig. 2C), the cumulative incidence of TKA was significantly lower for the osteophyte (+) group compared to the osteophyte (-) group in the Larsen grade III-V group (38% vs. 74% at 10 years, P=0.010) (Fig. 2D). Multivariate analysis using Cox proportional hazards models revealed that older age [hazard ratio (HR): 1.04 per 1 year, 95% confidence interval (CI): 1.01-1.08] and osteophyte formation (HR: 0.39, 95% CI: 0.19-0.79) independently predicted TKA in the Larsen grade III-V group, whereas none of the assessed variables predicted TKA in the Larsen grade 0-II group.Table 1.Baseline characteristics by presence or absence of osteophyte formationTotalOsteophyte (+)Osteophyte (-)Characteristicsn = 130n = 44n = 86PvalueAge, years57(41-63)59(52-65)56(39-63)0.051Sex, female, n (%)108(83)40(91)68(80)0.137Body mass index21.3(19.0-23.8)21.3(18.9-24.4)21.2(19.0-23.7)0.744Disease duration, years8(3-12)9(5-18)7(3-11)0.007Larsen grade, n (%)<0.001Grade 0-II66(51)11(25)55(64)Grade III-V64(59)33(75)31(36)Osteophyte formation, n (%)44(34)---RF or ACPA positive, n (%)85(83)35(90)50(78)0.183CRP, mg/dl3.2(1.5-4.9)2.9(1.0-4.1)3.4(1.8-5.2)0.172First biologic agent, n (%)1.000Infliximab57(44)19(43)38(44)Etanercept73(56)25(57)48(56)Use of methotrexate, n (%)98(75)33(75)65(76)1.000Methotrexate dose, mg/week*8(6-10)8(6-9)8(6-10)0.104Use of glucocorticoids, n (%)79(61)22(50)57(66)0.088Glucocorticoid dose, mg/day*†5.0(5.0-7.5)5.0(5.0-5.0)5.0(5.0-7.8)0.204Data are presented as median (interquartile range) or number of subjects (percentages). *Median among subjects receiving the drug. †Prednisolone equivalent (mg/day).Conclusion:Osteophyte formation reduces the incidence of TKA in patients with RA who have advanced joint damage.References:[1]Rau R.

Abstract
Background:Infliximab is still a widely used biologic agent in treatment of rheumatoid arthritis (RA). Because infliximab is expensive and can have adverse events, identification of factors that predict an adequate response to this treatment has been investigated.Objectives:In this study, we investigated the association between rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) status and the discontinuation of infliximab therapy due to adverse events or insufficient response in bio-naïve patients with RA.Methods:This study included patients enrolled in the Tsurumai Biologic Communication Registry in Japan. A crude comparison of infliximab discontinuation between seropositive and seronegative patients was using Kaplan-Meier analysis and log-rank test. We evaluated the associations between the specified baseline characteristics and discontinuation of infliximab therapy using Cox proportional hazard regression. We could not perform simultaneous assessments of the impact of RF and ACPA seropositivity on clinical efficacy becasue of collinearity.Results:Baseline characteristics of the patients included in this study are shown in Table 1 and the crude comparison between RF and ACPA status is shown in Figure 1. RF and ACPA seropositivity was significantly predictive of discontinuation of infliximab therapy after adjusting for baseline characteristics, including age, sex, stage, class, disease activity at baseline, and prednisolone use (Table 2). The hazard ratio was 1.99 (95% confidence interval 1.25, 3.18) for RF and 2.73 (95% confidence interval 1.24, 6.02) for ACPA.Table 1.Characteristics of RA patients at baseline by RF and ACPA statusRF (n = 344;ACPA (n = 250;985 patient-years)824 patient-years)RFRFACPAACPApositivenegativepositivenegative(n = 263)(n = 81)P†(n = 211)(n = 39)P†Age, years (SD)55.7 (12.3)54.6 (13.9)0.4855.4 (12.3)49.7 (14.3)0.01Female, no.

Abstract
Background:In Japan, oral tacrolimus (TAC) was approved for the treatment of RA in 2005 and the improvement of symptoms thorough the use concomitant with disease modifying antirheumatic drugs (DMARDs), including MTX has been reported1 2. On the other hand, the efficacy and tolerance of biological agents therapy concomitant with TAC are unknown.Objectives:The objective of this study was to investigate the efficacy and tolerance of biological agents concomitant with TAC in Japanese patients with RA using retention rate analysis.Methods:Total patients (n=2860) who underwent 5 biological agents (etanercept: ETN, adalimumab: ADA, golimumab:GLM, tocilizumab: TCZ, abatacept: ABT) treatment between 2003 and 2017 at Nagoya University Hospital and 12 other institutes (Tsurumai Biologics Communication Study Group) were enrolled3. In each biologics analysis, patients were divided into three groups: (1) concomitant only MTX (MTX group) (2) concomitant only TAC (TAC group) (3) others (others group). In TAC or MTX group, these drugs were only ones which concomitant with biologics. Kaplan-Meier analysis was used to estimate retention rate in each biologics group. To estimate the tolerance of concomitant biologics with TAC, cumulative hazard function in adverse events rate was performed in each biologics group. In both analyses, hazard ratios (HR) were assessed by Cox proportional hazards modeling adjusted for age, sex, disease duration and previously used biologics.Results:In total 2860 patients, 142 patients (5.0%) administered each biologics concomitant with TAC (ETN: n=47, ADA: n=10 GLM: n=14, TCZ: n=27, ABT: n=49). Baseline characteristics of 142 patients were shown in table 1. Average dosages of TAC at starting were ETN: 2.2±0.7mg ADA: 2.4±1.0mg GLM: 1.9±1.0mg TCZ: 1.7±0.9mg ABT: 1.9±0.9mg. With comparison of retention rate between 3 groups in each biologics under analysis of cox proportional hazard modeling, in ETN and ABT analysis, the retention rate of TAC group was higher than others group (table 2, figure 1). Comparison of incidence of adverse event between 3 group using cumulative hazard function and cox proportional hazard modeling in ETN and ABT analysis. In ETN analysis, incident rate of other group was higher than TAC group. In ABT analysis, there was no significant difference between 3 gruops (figure 2).Table 1.Baseline characteristic (n=142)age (years)63 ± 3gendermale33 (23%)female109 (77%)disease duration (years)12.0 ± 7.8stage1,234 (24%)3,4108 (76%)class1,299 (70%)3,443 (30%)naïve vs switchnaïve71 (50%)switch71 (50%)corticosteroid use, no (%)+98 (75%)-32 (25%)corticosteroid dose (mg)5.6 ± 3.2DAS28-ESR4.71 ± 1.55Table 2.HR (95%CI)/p-valuen (MTX/TAC/others)ETNADAGLMTCZABT(774/ 47/ 486)(339/ 10/ 135)(156/ 14/ 61)(272/ 27/ 207)(213/ 49/ 178)TAC vs others0.27 (0.16-0.45)<0.0010.9 (0.37-2.20)ns0.46 (0.13-1.63)ns0.55 (0.24-1.31)ns0.51 (0.26-0.97)<0.05TAC vs MTX0.65 (0.38-1.08)ns1.42 (0.61-3.31)ns0.83 (0.24-2.87)ns0.5 (0.21-1.17)ns0.74 (0.39-1.42)nsMTX vs others0.42 (0.35-0.50)<0.0010.9 (0.50-0.88)<0.0010.56 (0.33-0.96)<0.051.01 (0.78-1.57)ns0.68 (0.46-0.99)<0.05Bold italic: p<0.05CI: confidence interval ns: not significantConclusion:We suspected that, in ETN and ABT treatment, combination therapy with TAC are subsequent options for treatment to RA patients, especially in whom MTX cannot be administration.References:[1]Kino T, et al.

Abstract
Background:Baricitinib is considered as a specific JAK1/2 inhibitor. While a number of randomized controlled trials have reported on the clinical efficacy and safety profile of baricitinib in rheumatoid arthritis (RA) patients, clinical data for RA patients in routine clinical practice are scarce.Objectives:This study aimed to evaluate the short-term effectiveness and safety profiles of baricitinib and explore factors associated with improved short-term effectiveness in patients with RA in clinical settings.Methods:A total of 113 consecutive RA patients who had been treated with baricitinib were registered in the TBCR, a Japanese multicenter registry for RA patients treated with biologics or JAK inhibitors (targeted DMARDs) [3], and followed for at least 24 weeks. Univariate and multivariate logistic regression analysis was used to study predictive factors for achievement of low disease activity (LDA) at 24 weeks.Results:Mean age was 66.1 years, mean RA disease duration was 14.0 years, 71.1% had a history of use targeted DMARDs, and 48.3% and 40.0% were receiving concomitant methotrexate (MTX) and oral prednisone, respectively. Mean DAS28-CRP significantly decreased from 3.55 at baseline to 2.32 at 24 weeks (Figure 1A). At 24 weeks, 68.2% and 64.1% of patients achieved LDA and moderate or good response, respectively (Figure 1B). Multivariate logistic regression analysis revealed that no previous targeted DMARD use and lower DAS28-CRP score at baseline were independently associated with achievement of LDA at 24 weeks (Table). While the percent change in DAS28-CRP was similar regardless of whether patients used concomitant MTX (Figure 2A), patietns with previous use of targeted DMARDs (Switch group) showed lower percent improvement in DAS28-CRP compared to targeted DMARDs-naïve patients (Naïve group) (Figure 2B). The overall retention rate for baricitinib was 86.5% at 24 weeks, as estimated by Kaplan-Meier analysis. The discontinuation rate due to adverse events was 6.5% at 24 weeks. In the present study cohort, seven patients developed herpes zoster, with an incidence rate of 8.4 per 100 patient-years. All seven patients were treated with antiviral agents for herpes zoster and restarted baricitinib treatment.TableUnivariateMultivariatevariablesOR (95%CI)p-valueadjusted OR (95%CI)p-valueMale1.17 (0.43-3.16)0.755Age, <65 years1.46 (0.62-3.44)0.388Disease duration, <10 years1.41 (0.61-3.23)0.419ACPA positive1.56 (0.51-4.80)0.433no previous biological DMARDs4.67 (1.49-14.66)0.00833.4 (2.53-442.62)0.008concomitant MTX0.860 (0.40-2.02)0.789concomitant PSL0.24 (0.10-0.56)0.001DAS28-CRP@baseline0.55 (0.38-0.80)0.0020.28 (0.13-0.62)0.002mHAQ@baseline0.27 (0.09-0.77)0.015Bold italic, p<0.05Conclusion:In this study, we demonstrated the short-term clinical effectiveness and safety profile of baricitinib in Japanese RA patients in the ‘real-world’ setting. To the best of our knowledge, this study is the first to report the clinical outcomes of baricitinib in routine clinical practice in Japan. Baricitinib significantly improved disease activity, with an expected safety profile. We observed some interesting features regarding the effectiveness of baricitinib. Baricitinib was significantly more effective when used as a first-line targeted DMARD and may play a key role in the modern treatment strategy for RA, although careful observation is necessary for possible complications and AEs including herpes zoster.References:[1]Taylor PC, et al.

Abstract
Background:All biologics should primarily be combined with a conventional synthetic DMARD, such as methotrexate (MTX), in rheumatoid arthritis (RA) patients. However, the use of MTX may lead to the development of adverse events (AEs), and de-escalation of MTX while maintaining a favorable disease activity state may be beneficial from the perspective of reducing AEs during long-term RA treatment. Several studies have evaluated the impact of MTX discontinuation in RA patients who achieved good clinical response with tocilizumab (TCZ) plus MTX combination therapy, finding that discontinuing MTX is noninferior to continuing MTX in terms of maintaining clinical response (1-3). However, information on risk factors for disease flare after MTX discontinuation is lacking.Objectives:To investigate predictors of disease flare after MTX discontinuation in Japanese RA patients with sustained low disease activity undergoing TCZ plus MTX combination therapy.Methods:Participants of this multicenter, open-label, uncontrolled, prospective study were RA patients maintaining low disease activity (Clinical Disease Activity Index [CDAI] ≤10) for ≥12 weeks with TCZ plus MTX. Patients had to be receiving MTX orally at a stable dose of ≥6 mg/week, and TCZ at a stable dosage regimen irrespective of the route of administration, for ≥12 weeks prior to obtaining informed consent. MTX was discontinued after 12 weeks of biweekly administration while continuing TCZ therapy (Fig. 1). Disease flare was defined as a CDAI score >10 or intervention with rescue treatments for any reason. The impact of baseline characteristics on disease flare at week 64 (52 weeks after MTX discontinuation) was assessed with logistic regression models.Results:Efficacy analyses were performed in 49 patients, of whom 15 had a disease flare by week 64. The proportion [95% confidence interval (CI)] of patients who maintained low disease activity without a flare at week 64 was 69.4% (54.6 – 81.8%) (Fig. 2A). According to Kaplan-Meier estimates, the cumulative flare-free rate was 70.0% at week 64 (Fig. 2B). The dosing interval of TCZ was longer than that described on the drug label (i.e., intravenously every 4 weeks, or subcutaneously every 2 weeks) in 27% and 6% of patients with and without a flare, respectively (Table 1). Multivariate analysis revealed that male sex [odds ratio (OR): 18.00, 95% CI: 2.80-115.56] and extended dosing interval of TCZ (OR: 12.00, 95% CI: 1.72-83.80) were independent predictors of disease flare.Table 1.Impact of baseline variables on disease flareNon-flareFlareOdds ratio (95% confidence interval)(n=34)(n=15)UnivariateMultivariateAge, years62 ± 1163 ± 91.01 (0.95-1.08)aMale, %64010.67 (1.83-62.18)*18.00 (2.80-115.56)*Weight, kg54 ± 858 ± 151.03 (0.98-1.09)aDisease duration, years11 ± 813 ± 91.03 (0.95-1.11)aRF positive, %76861.85 (0.34-10.04)ACPA positive, %85100-bRoute of TCZ, intravenous, %59802.80 (0.66-11.79)Extended TCZ dosing interval, %6275.82 (0.93-36.28)†12.00 (1.72-83.80)*MTX dose, mg/week8.2±2.28.0±2.60.95 (0.73-1.25)aUse of glucocorticoids, %26331.39 (0.37-5.18)Use of csDMARDs other than MTX, %9335.17 (1.04-25.57)*-Previous biologic use, %56803.16 (0.75-13.26)CDAI remission, %65731.50 (0.39-5.75)CRP, mg/dl0.04 ± 0.060.04 ± 0.060.42 (0.00-15115.38)aMMP-3, ng/ml58.5 ± 22.476.6 ± 37.61.02 (1.00-1.05)a†-Data are shown as mean ± SD or percentage.aOdds ratio for 1-unit increase in each item.bOdds ratio was not evaluated. *P<0.05. †P<0.10.Conclusion:Male patients and those receiving TCZ at an extended dosing interval are at high risk of disease flare after discontinuation of concomitant MTX.This work was supported by Chugai Pharmaceutical Co., Ltd.References:[1]Kremer JM.

Abstract
Background:Cervical lesions are known to occur at high frequency as a complication of rheumatoid arthritis (RA). Treatment with biological agents are more clinically effective than the DMARDs that were in use previously, in particular, with their efficacy in suppressing joint destruction having been emphasized. We reported the efficacy of infliximab, anti-tumor necrosis factor antibodies for suppressing the radiographic progression of RA cervical lesions at ACR2009, EULAR2010, 11, 12, 13, 14,16 and 18. However there is still few studies of efficacy of against RA cervical lesions of Abatacept (ABT) that inhibits T cell activation by binding to CD80/86.Objectives:To evaluate the efficacy of ABT for suppressing the radiographic progression of RA cervical lesions comparison with MTX for 2 years.Methods:We used ABT or MTX for treating Japanese patients with active RA who fulfilled the ACR criteria in 1987. The final study cohort of each 60 and 75 patients received continuous ABT and MTX treatment for at least 2 years. For evaluation of cervical lesions, the atlanto-dental interval (ADI), the space available for the spinal cord (SAC), and the Ranawat value were measured by plain lateral radiographs in the flexion position, at initiation and Year 1,2.Results:In the patients receiving ABT (n=60) and MTX (n =75), the number of female were each 48(80%) and 52(69%) cases(p=0.160). The mean age was 67.7 ± 12.9 and 63.6 ± 11.0 years old (p=0.004); disease duration was 16.7 ± 14.2 and 8.0 ± 9.5 years (p<0.001) and the mean dose of MTX was 8.4 ± 3.6 and 8.2 ± 2.9 mg/w (p=0.804). Clinical findings related to RA were as follows; CRP 2.2± 2.1 and 1.7± 2.3 mg/dl(p=0.008); ESR 47.2 ± 23.4 and 31.9 ± 21.8mm/h(p<0.001); MMP3 253 ± 280 and 223 ± 350ng/ml(p=0.003); the number of RF-positive 57(95%) and 60(80%) cases(p=0.011); DAS28-ESR 5.13 ± 0.99 and 4.30 ± 1.38 (p<0.001); ADI 3.6 ± 2.1 and 2.6 ± 1.6mm(p=0.003); SAC 18.5 ± 2.8 and 20.8 ± 2.5mm(p<0.001) and Ranawat value 14.4 ± 1.9 and 16.0 ± 1.5mm (p<0.001). The respective changes in cervical lesion parameters after 1 year were as follows: ADI: 0.20 ± 0.40 and 0.27 ± 0.45 mm (p = 0.367); SAC: −0.12 ± 0.32 and −0.17 ± 0.38 mm (p = 0.359); and Ranawat value: −0.15 ± 0.36 and −0.13 ± 0.34 mm (p = 0.783). The respective changes in cervical lesion parameters after 2 years were as follows: ADI: 0.35 ± 0.58 and 0.55 ± 0.70 mm (p = 0.099); SAC: −0.25 ± 0.47 and −0.45 ± 0.62 mm (p = 0.047); and Ranawat value: −0.23 ± 0.47 and −0.33 ± 0.55 mm (p = 0.293) in the patients receiving ABT and MTX (Fig. 1). The numbers of patients who did not showed progression in ADI, SAC and Ranawat value were each 42(70%) and 43(57%) cases(p=0.130); 46(77%) and 46(61%) cases(p=0.057) and 47(78%) and 53(71%) cases(p=0.313) after 2 years. Also the number who was able to suppress progression in all three parameters were each 42 cases (70%) receiving ABT and 43 cases (57%) receiving MTX (p=0.130) after 2 years (Fig. 2).Conclusion:This study suggested that ABT treatment can be used to suppress the progression of RA cervical lesions more than MTX treatment.Disclosure of Interests:Yasuhide Kanayama: None declared, Toshihisa Kojima Grant/research support from: Chugai, Eli Lilly, Astellas, Abbvie, and Novartis, Consultant of: AbbVie, Speakers bureau: AbbVie, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eli Lilly, Janssen, Mitsubishi Tanabe, Pfizer, and Takeda, Yuji Hirano Speakers bureau: Tanabe-Mitsubishi, Pfizer, Eisai, Abbie, Chugai, Bristol-Meyers, Jansen, Astellas, UCB, Eli-Lilly, Asahikasei, Daiichi-Sankyo, Amgen, Nobunori Takahashi Speakers bureau: AbbVie, Asahi Kasei, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eisai, Eli Lilly, Janssen, Mitsubishi Tanabe, Ono, Pfizer, Takeda, and UCB Japan, Yukiyoshi Oishi: None declared, Naoki Ishiguro Grant/research support from: AbbVie, Asahi Kasei, Astellas, Chugai, Daiichi-Sankyo, Eisai, Kaken, Mitsubishi Tanabe, Otsuka, Pfizer, Takeda, and Zimmer Biomet, Consultant of: Ono, Speakers bureau: Astellas, Bristol-Myers Squibb, Daiichi-Sankyo, Eli Lilly, Pfizer, and Taisho Toyama

Abstract
Background:Glucocorticoids exert anti-inflammatory effects and are important drugs used to treat rheumatoid arthritis(1). We recommend glucocorticoid discontinuation as soon as possible because glucocorticoid caused several side effects, but many patients continue to take oral glucocorticoids long-term in daily clinical practice. The frequency of use of glucocorticoid has gradually declined, and there are several reports on discontinuation of glucocorticoid due to the initiation of biological disease-modifying antirheumatic drugs (bDMARDs)(2). However, there is no report showing the relation between discontinuation of glucocorticoid and MTX dose.Objectives:The present study aimed to explore factors associated with glucocorticoid discontinuation at 52 weeks after initiating bDMARDs.Methods:We established the large observational cohort, the Nagoya University orthopedic facility multicenter study (TBCR), and a total of 3119 patients used bDMARD and examined the status of oral glucocorticoid use at 52 weeks after initiating the 1stbDMARD. In predictive analyses, the outcome variable was glucocorticoid discontinuation at 52 weeks after bDMARD initiation. Factors associated with baseline characteristics at bDMARD initiation were assessed with univariate and stepwise forward multivariate logistic regression analyses. This cohort study was not randomized. Propensity score (PS) matching was used to align patient backgrounds to avoid selection bias.Results:Subjects were 564 patients administered glucocorticoids and methotrexate (MTX) following initiation of the 1stbDMARD (Figure 1). Mean DAS28-CRP at bDMARD initiation was 4.70 ± 1.16. Percentages of patients with low, moderate, and high disease activity as evaluated by DAS28-CRP at bDMARD initiation were 4.7%, 23.5%, and 71.8%, respectively. By 52 weeks after bDMARD initiation, 164 patients (29.1%) discontinued glucocorticoids. Multivariate analysis identified age (odds ratio (OR), 0.98), MTX dose (OR, 1.11), and glucocorticoid dose (OR, 0.87) as factors independently associated with glucocorticoid discontinuation at the time of bDMARD initiation (Table 1). After adjusting for baseline characteristics using propensity score matching among patient groups administered MTX ≤ 8 mg/week and MTX > 8 mg/week, 105 pairs remained. Among patients administered MTX > 8 mg/week, 41.0% discontinued glucocorticoids. Among those administered MTX ≤ 8 mg/week, 22.9% discontinued glucocorticoids, with a significant difference between the two groups (Figure 2, P=0.007).Table 1.Factors associated with baseline characteristics at bDMARD initiationContinuation(n=400)Discontinuation(n=164)UnivariateOdds ratio (95% CI)MultivariateOdds ratio (95% CI)Age, years58.4 ± 12.954.3 ± 14.30.98 (0.97-0.99)*0.98 (0.97-0.99)*Disease duration, years9.4 ± 9.47.5 ± 8.50.98 (0.95-0.99)*–Female, %80.381.11.06 (0.67-1.68)–DAS28-CRP4.78 ± 1.154.50 ± 1.160.81 (0.69-0.96)*–Seropositivity, %90.086.10.69 (0.38-1.25)–MTX dose, mg/week7.7 ± 2.58.8 ± 3.01.16 (1.09-1.24)*1.11 (1.03-1.21)*Glucocorticoid dose, mg/day4.9 ± 2.14.3 ± 2.10.86 (0.78-0.95)*0.87 (0.78-0.97)*TNF inhibitor use, %88.885.40.74 (0.43-1.26)-Data are presented as mean ± standard deviation.Conclusion:Data from the TBCR revealed that, from a clinical perspective, glucocorticoid use decreased among RA patients treated with bDMARDs. Higher doses of MTX (> 8 mg/week) at the time of bDMARD initiation were found to be associated with glucocorticoid discontinuation in patients treated with bDMARDs. In addition, we found that aggressive use of MTX was sufficient to fulfill the Treat-to-Target approach, demonstrating that glucocorticoid discontinuation is a viable option.References:[1]Smolen JS.

Abstract
Background:We recently reported that the inhibitor of hyaluronan (HA) biosynthesis, 4-methylumbelliferone (4-MU) blocked IL-1β activation of MMP13 mRNA and protein expression in human osteoarthritic (OA), bovine as well as bovine or OA cartilage explants [1]. This was a somewhat counterintuitive observation because we have also demonstrated that the overexpression of HAS2 (HAS2-OE) exerted the same chondroprotective effects on human and bovine chondrocytes. Others [2] have reported that HAS2-OE in tumor cells generates a flux in intracellular UDP-sugar pools that resulted in changes in cell metabolism; switching from a dependence on glycolysis to aerobic respiration. HAS2-OE and 4-MU likely also cause dramatic fluxes in intracellular UDP-GlcUA pools. From these results, we hypothesized that the effect of HAS2-OE and 4-MU relate to changing metabolism and the possibility of inhibition of glycolysis induce chondroprotective effect. To determine that, we used the glycolysis inhibitor, 2-Deoxyglucose (2DG) as an alternative agent to change metabolism in chondrocytes.Objectives:The objective of this study was to investigate the mechanism of chondroprotective effects of 2DGMethods:Bovine and human chondrocyte were stimulated with IL-1β (2ng/ml) in the presence or absence of 4MU (1.0 mM), 2DG (0.2-20 mM). Bovine chondrocytes were tested using Seahorse Flux Analyzer (Agilent Tech) to determine rate changes in medium accumulation of +H protons (indicative of lactic acid accumulation: ECAR) and for O2 consumption (indicative of mitochondrial respiration: OCR). Accumulation of MMP13 and phosphor AMPK (pAMPK) protein was quantified with Western blotting. Human and Bovine cartilage explants were cultured with L-1β in the presence or absence of 2DG (20 mM) and d 5-Aminoimidazole-4-carboxamide 1-β-D-ribofuranoside (AICAR) to pharmacologically induce AMPK for 7 days and stained with Safranin O.Results:Reduced mitochondrial potential and enhanced dependence on glycolysis was observed in IL-1β stimulated chondrocytes. Co-treatment with 4-MU and 2DG returned the cell metabolism to levels at or below baseline (Fig 1A, B). The Seahorse ATP Rate Assay means the contributions of glycolysis and mitochondrial respiration to chondrocyte ATP production (Fig 1C). In control chondrocytes, the use of glycolysis contributes to the majority of ATP produced (grey bars) approximately 1/5th from the TCA cycle (red bars). IL1β-activated chondrocytes display increase in glycolysis and decrease in mitochondrial contributions. These changes are reversed by co-treatment with 4MU and 2DG. As shown in Figs 2A, 2DG reversed the IL1β-induced increases accumulation of MMP13 protein in human OA chondrocytes by Western blotting analysis. Although IL-1β lost safranin O staining in human and bovine samples, co-incubation with 2DG blocked in the loss of proteoglycan (Fig 2B). pAMPK is associate with energy homeostasis in chondrocytes. IL-1β treatment decreased accumulation of phosphor AMPK. Co-treatment with 4-MU and 2DG resulted in a rescue of the pAMPK status (Figure 3A). Co treatment with AICAR, which is inducer of AMPK, also blocked in the loss of proteoglycan (Fig 3B).Conclusion:4-MU and 2DG have chondroprotective effect by changing metabolism and upregulate AMPK. We propose that 4MU and 2DG become useful when these endogenous responses are not enough to rescue cells from a pro-catabolic phenotype.References:[1]J. Biol. Chem. 291:12087, 2016; [2] J. Biol.

Abstract
Background:EULAR has issued updated guidelines for the management of rheumatoid arthritis (RA) using conventional, biologic, and targeted synthetic DMARDs. In the 2019 update, the task force revised the preference of bDMARDs over tsDMARDs. In routine clinical practice, baricitinib is commonly used as second line or after. However, there is little information about the clinical efficacy and safety profile of baricitinib after failure of the previous agent, including another tsDMARD.Objectives:The aim of this study was to evaluate the short-term effectiveness and safety profiles of baricitinib after insufficient response (IR) to bDMARDs or tsDMARDs in patients with RA in clinical settings.Methods:RA patients who had been treated with baricitinib after failure of the previous agent were registered in the TBCR, a Japanese multicenter registry for RA patients treated with biologics or JAK inhibitors and followed for at least 24 weeks. Patients were divided into two groups according to the cause of failure of the previous treatment; IR (“After IR” group) and the others (“After non-IR” group). “After IR” group was further divided into four groups according to the previous agent; TNF inhibitor (TNFi group), IL-6 receptor inhibitor (IL-6Ri group), abatacept (ABT group) and tofacitinib (Tofa group). We assessed disease activities by CDAI score and drug retention rates between these groups. Furthermore, discontinuation rates due to IRs and adverse events (AEs) were evaluated.Results:A total of 86 consecutive RA patients were registered in this study. The previous treatment was as follows; TNF inhibitor: 38 (44.2%), IL-6 receptor inhibitor: 23 (26.7%), abatacept: 11 (12.8%), tofacitinib: 13 (15.1%) and the other: 1 (1.2%).The cause of failure of the previous therapy were IRs (n=74: 86%), AEs:(n=6: 7.0%) and the others (n=6: 7.0%). In “After IR” group, the most common previous agents were TNFis (Table 1). While the percent change in CDAI was decreased at week 12 in all groups, those in Tofa group showed lower rates of improvement in CDAI compared to the others at week 24 (Figure 1). Drug retention rate at 24-week was 59.4% in TNFi group, 90.5% in IL-6Ri group, 54.5% in ABT group and 77.8% in Tofa group (Figure 2). In the present study cohort, seven patients developed herpes zoster. All seven patients were treated with antiviral agents for herpes zoster and restarted baricitinib treatment (these cases were not treated as discontinuation due to AEs in this study). The overall Cumulative discontinuation rate due to IRs and AEs at 24 weeks were 9.7% and 7.3%, respectively.Table.Clinical characteristics of the BAR2mg group and the BAR4mg groupGroupsCases; n (%)TNFi group32 (43.2)IL-6R group21 (28.4)ABT group11 (14.9)Tofa group9 (12.2)The oter1 (1.4)Conclusion:In this study, we demonstrated the short-term effectiveness and safety profiles of baricitinib after insufficient response to bDMARDs or tsDMARDs in patients with RA in the ‘real-world’ setting. Baricitinib improved disease activity after failure of the previous agent, even after IR to another tsDMARD. With respect to safety, the profile is almost tolerable, although careful observation is necessary for possible complications and AEs including herpes zoster.Disclosure of Interests:Hanabayashi Masahiro Speakers bureau: Astellas Pharma Inc., Mitsubishi Tanabe Pharma Corporation, Eisai Pharma Corporation, Chugai Pharma Corporation, abbvie, Bristol-Myers Squibb, Pfizer, Janssen Pharmaceutical K.K., Eli Lilly Japan K.K. and UCB Japan, Nobunori Takahashi Speakers bureau: AbbVie, Asahi Kasei, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eisai, Eli Lilly, Janssen, Mitsubishi Tanabe, Ono, Pfizer, Takeda, and UCB Japan, Toshihisa Kojima Grant/research support from: Chugai, Eli Lilly, Astellas, Abbvie, and Novartis, Consultant of: AbbVie, Speakers bureau: AbbVie, Astellas, Bristol-Myers Squibb, Chugai, Daiichi-Sankyo, Eli Lilly, Janssen, Mitsubishi Tanabe, Pfizer, and Takeda

Abstract
Abstract
Introduction
Approximately two thirds of children with Autism Spectrum Disorder (ASD) suffer from chronic insomnia. Current behavioral interventions for insomnia in children with ASD use sleep hygiene guidelines to educate parents and their children regarding sleep promoting habits. However, the relationship between pre-bedtime physical activity/light and sleep is understudied in ASD. The current study examined daily associations between pre-bedtime actigraphically assessed activity/light levels and objective/subjective sleep outcomes in children with ASD and insomnia.
Methods
Thirty children (Mage=8.5 yrs, SD=1.78 yrs) with comorbid ASD and insomnia completed 14 days of actigraphy measuring ambient white light intensity and activity levels every 30 seconds. Validated sleep scoring algorithms (in Actiware V. 6.0.9) estimated objective sleep onset latency (SOL), total sleep time (TST), wake time after sleep onset (WASO), and average activity/light levels 30, 60, and 120 mins prior to bedtime. Additionally, average activity/light levels 120-240, and 240-360 mins prior to bedtime were computed. Children also completed 14 daily sleep diaries (with parental assistance) measuring subjective reports of the same sleep parameters. Associations between daily estimations of pre-bedtime activity levels, light, and nighttime objective and subjective sleep were examined through multilevel modelling. Bonferroni corrections were performed to account for multiple comparisons.
Results
After Bonferroni corrections (p<.025 significance level), greater activity within 30 minutes (B=0.0465, p=.0093) and 60 minutes (B=0.0681, p=.0005) of bedtime were associated with longer subjective SOL. Pre-bedtime light exposure was not a significant predictor of sleep outcomes.
Conclusion
Results suggest that in general, variations in daily pre-bedtime activity, but not light, are associated with worse nightly subjective SOL in children with ASD and insomnia. Findings support that sleep hygiene recommendations in children with ASD include avoidance of higher levels of pre-sleep physical activity. Prospective studies examining temporal causal relationships between pre-bedtime activity and sleep in ASD are warranted.

Abstract
Macrophages are immune cells with high plasticity that perform many functions related to tissue injury and repair. They are generally categorized as 2 functional phenotypes: M1 (proinflammatory) and M2 (anti-inflammatory and prohealing). To investigate the role of macrophages in human dental pulp, we examined the localization and distributional alterations of macrophages in healthy dental pulp as well as during the reparative process of pulp capping with mineral trioxide aggregate (MTA) and in cariously inflamed pulp of adult human teeth. We also quantified the populations of M1/M2 macrophages in healthy dental pulp by flow cytometric analysis. CD68+CD86+ cells (M1 phenotype) and CD68+CD163+ cells (M2 phenotype) were 2.11% ± 0.50% and 44.99% ± 2.22%, respectively, of 2.96% ± 0.41% CD68+ cells (pan-macrophages) in whole healthy dental pulp. Interestingly, M2 phenotype macrophages were associated with Schwann cells in healthy pulp, during mineralized bridge formation, and in pulp with carious infections in vivo. Furthermore, the M2 macrophages associated with Schwann cells expressed brain-derived neurotrophic factor (BDNF) under all in vivo conditions. Moreover, we found that plasma cells expressed BDNF. Coculture of Schwann cells isolated from human dental pulp and human monocytic cell line THP-1 showed that Schwann cells induced M2 phenotypic polarization of THP-1 cell-derived macrophages. The THP-1 macrophages that maintained contact with Schwann cells were stimulated, leading to elongation of their cell shape and expression of M2 phenotype marker CD163 in cocultures. In summary, we revealed the spatiotemporal localization of macrophages and potent induction of the M2 phenotype by Schwann cells in human dental pulp. M2 macrophages protect neural elements, whereas M1 cells promote neuronal destruction. Therefore, suppressing the neurodestructive M1 phenotype and maintaining the neuroprotective M2 phenotype of macrophages by Schwann cells may be critical for development of effective treatment strategies to maintain the viability of highly innervated dental pulp.

Abstract
PURPOSE Assessing the papillomacular nerve fiber bundle (PMB) can identify glaucoma patients with decreased visual acuity. In this study, we explore efficient methods for evaluating PMB thickness in glaucoma patients, based on swept source-optical coherence tomography (SS-OCT). METHODS This study included 347 eyes of 205 open-angle glaucoma (OAG) patients. Patients were excluded if they had best-corrected decimal visual acuity < 0.3, axial length >28 mm, non-glaucoma ocular disease, or systemic disease affecting the visual field. We obtained vertical 12.0 × 9.0 mm 3D volume scans covering both the macular and optic disc regions with SS-OCT (DRI OCT Triton, Topcon), and measured the thickness of the PMB, as well as average macular retinal nerve fiber layer thickness (mRNFLT) and macular ganglion cell complex thickness (mGCCT) in the macular map and temporal-quadrant circumpapillary RNFL thickness (tcpRNFLT). We also measured central-strip RNFLT (csRNFLT) and GCC (csGCCT) in a 1.5 × 6.6 mm area of the scan centered between the fovea and optic nerve head. CsRNFLT and csGCCT were divided lengthwise into three 1.5 × 2.2 mm sections. We then calculated Spearman's rank correlation coefficient between these OCT measurements and visual acuity. Logistic regression analysis was used to find the cutoff value for the OCT measurements to predict logMAR < 0. RESULTS The correlation coefficients with logMAR were 0.38 for mRNFLT, 0.44 for mGCCT, 0.37 for middle csRNFLT, 0.50 for middle csGCCT, and 0.33 for tcpRNFLT (all P < .0001). For middle csGCCT, the area under the curve indicating decreased visual acuity was 0.80, with a cutoff value of 88.6 μm (P < .001). CONCLUSIONS We found strong associations between OCT parameters in the PMB, especially middle csGCCT, and visual acuity in patients with OAG. The thickness of the PMB may therefore be valuable information for glaucoma care and may help prevent visual acuity disturbance.

Abstract
Abstract
Background
Reducing delay to percutaneous coronary intervention improves functional outcome and reduces long-term mortality. Transportation by helicopter is often quicker than ground transport and thus may improve overall prognosis through reduced ischemic injury and infarction size. Our hospital is located on the medically-depopulated peninsula surrounded by mountain. The journey from the southern tip of the peninsula to the critical care medical center of our hospital take 1.5 hour by a ground ambulance but only 15 minutes by helicopter.
We compared the clinical characteristics and long-term mortality between air and ground transport of ACS patients for primary PCI.
Methods
We conducted an observational cohort study evaluating 2324 patients (mean age 68.5±12.0, male 75.2%) with ACS underwent primary PCI between April 2004 and December 2017 at our hospital.
We divided into three groups according to transportation system type (air, ground, walk-in).
The primary outcome was defined as all-cause death during the long-term follow-up.

Among the entire cohort, 577 patients (24.8%) were transported by air. 1326 (57.1%) patients by ambulance, 421 (18.1%) patients by walk. Baseline characteristics were comparable, but patients by air had a higher prevalence of ST-elevation myocardial infarction.
The rate of long-term mortality was comparable during the median follow up of 6 years (air, 21.1% vs. ground, 21.4% vs. walk-in, 21.1%, respectively, log-rank p=0.72). Multivariate Cox regression analysis showed no significant association between air transportation and long-term mortality (Adjusted HR [vs ground] 1.05, 95% CI 0.60–1.78, p=0.85 and [vs walk-in] 0.94, 95% CI 0.62–1.43, respectively, p=0.77).

Abstract
Abstract
Background
Hemodynamic disturbance in acute heart failure (HF) can cause injury to extra-cardiac organs such as the liver. Organ injury in HF might evoke a profibrotic response, which could adversely affect the prognosis.
Methods
Among 189 patients with acute HF, we simultaneously determined the liver fibrosis marker, type IV collagen 7S (P4NP 7S) and the Enhanced Liver Fibrosis (ELF) Score consisting of tissue inhibitor of metalloproteinases 1 (TIMP-1), amino-terminal propeptide of type III procollagen (PIIINP) and hyaluronic acid (HA) on admission and at discharge.
Results
During hospitalization, P4NP 7S and ELF score significantly decreased from 7.1 ng/mL to 6.1 ng/mL (P<0.001) and 10.39 to 10.13 (P<0.001), respectively. P4NP 7S and ELF score were correlated with each other on admission (r=0.4, P<0.001) and at discharge (r=0.4, P<0.001). %Change of (Δ) P4NP 7S during hospitalization was correlated with ΔBNP and ΔELF score (r=0.3, P<0.001 and r=0.4, P<0.001, respectively). Among the components of ELF score, PIIINP and HA were correlated with P4NP 7S on admission (r=0.5, P<0.001 and r=0.3, P<0.001, respectively) and at discharge (r=0.4, P<0.001 and r=0.3, P<0.001, respectively). ΔP4NP 7S was also correlated with ΔTIMP-1, ΔPIIINP and ΔHA (r=0.3, P<0.001, r=0.4, P<0.001 and r=0.3, P<0.001, respectively). Each patient was followed up up to 365 days after discharge. 69 patients died or were hospitalized for HF. When the patients were divided into two groups according to the median value of each marker at discharge, the cumulative 1-year incidences of all cause death or HF hospitalization were 32.0% and 45.5% in P4NP 7S-low and P4NP 7S-high group, respectively (log-rank P=0.051) and 43.2% and 34.9% in ELF score-low and ELF score-high group, respectively (log-rank P=0.44). After adjustment by the clinically relevant factors including age, sex, hemoglobin, sodium and left ventricular ejection fraction, P4NP 7S showed independent prognostic value (adjusted hazard ratio: 1.12, P=0.02), while ELF score did not (adjusted hazard ratio: 1.04, P=0.79).
Conclusion
Parallel elevation of P4NP 7S and ELF score were documented during acute phase of HF. P4NP 7S at discharge may identify patients at high risk for subsequent HF related events.

Abstract
Abstract
Background
Cardiac hypertrophy is a compensatory response to pressure overload that leads to heart failure. Recent studies have shown that Rho signaling has crucial regulatory roles in actin cytoskeleton rearrangement during cardiac hypertrophic responses. Rho is rapidly activated in response to pressure overload, but the mechanisms by which Rho and its downstream proteins control actin dynamics during hypertrophic responses remain unclear.
Objective
To identify the essential roles of mDia1 (Rho-effector molecule) in pressure overload-induced ventricular hypertrophy.
Methods and results
Male wild-type (WT) and mDia1-knockout (mDia1KO) mice (10–12 weeks old) were subjected to transverse aortic constriction (TAC) or a sham operation. The heart weight/tibia length ratio, cardiomyocyte cross-sectional area, left ventricular wall thickness, and expression of hypertrophy-specific genes were significantly decreased in mDia1KO mice 3 weeks after TAC, and the mortality rate was higher at 12 weeks. Echocardiography and the pressure-volume loop indicated that mDia1 deletion increased the severity of heart failure 8 weeks after TAC. Microarray gene expression profiling showed that the induction of immediate early genes due to the TAC operation was significantly lower in mDia1KO mice than WT mice, as was the activation of extracellular signal-regulated kinase (ERK) and focal adhesion kinase (FAK). We examined the role of mDia1 in neonatal rat ventricular cardiomyocytes (NRVMs) exposed to mechanical stress. The siRNA-mediated silencing of mDia1 attenuated stretch-induced ERK and FAK phosphorylation, and gene expression of c-fos. Importantly, loss of mDia1 suppressed an increase in the F/G-actin ratio in response to pressure overload in the mice. In addition, increases in nuclear myocardin-related transcription factors (MRTFs) and serum response factor (SRF) were perturbed in response to pressure overload in mDia1KO mice and to mechanical stretch in mDia1 depleted NRVMs.
Conclusions
Rho-mDia1, through actin dynamics, plays critical roles in pressure overload-induced hypertrophy by regulating ERK and FAK phosphorylation and the transcriptional activity of MRTF-SRF.
