Sci Rep 2021; 11:21555. [PMID: 34732807 PMCID: PMC8566570 DOI: 10.1038/s41598-021-01132-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Accepted: 10/20/2021] [Indexed: 12/15/2022] Open
Abstract
The clinical data on the biologic disease-modifying antirheumatic drug (bDMARD) use in late-onset ankylosing spondylitis (LOAS) is limited. Thus, this study aimed to evaluate the drug efficacy and retention rate of bDMARDs in LOAS and compare it to young-onset ankylosing spondylitis (YOAS). Data of patients with AS receiving bDMARDs were extracted from the Korean College of Rheumatology Biologics and Targeted Therapy registry. Patients whose age of onset was > 50 years and ≤ 50 years were classified as having LOAS and YOAS, respectively. Their baseline characteristics and disease-associated parameters were evaluated. Drug efficacy [Ankylosing Spondylitis Disease Activity Score (ASDAS)-clinically important improvement (CII), ASDAS-major improvement (MI), Assessment of SpondyloArthritis International Society (ASAS) 20, and ASAS 40] at 1-year follow-up and drug retention rates were assessed. A total of 1708 patients (comprising 1472 patients with YOAS and 236 patients with LOAS) were included in this analysis. The LOAS group had a lower prevalence among males, lower HLA-B27 positivity and a higher prevalence of peripheral arthritis. Patients with LOAS were more likely to have higher disease-associated parameters (inflammatory reactants, patient global assessment, ASDAS-erythrocyte sedimentation rate, and ASDAS-C-reactive protein). LOAS was negatively associated with achieving ASDAS-CII, ASAS 20, and ASAS 40. The drug retention rate was lower in LOAS; however, the propensity score-matched and covariate-adjusted hazard ratios for bDMARD discontinuation were comparable to YOAS. There were no differences in the drug retention rates based on the type of bDMARD used in LOAS. Inferior clinical efficacy and shorter drug retention time were found in patients with LOAS receiving bDMARDs using real-world nationwide data. There were no differences among each bDMARD type.

IL-18 binding protein suppresses IL-17-induced osteoclastogenesis and rectifies type 17 helper T cell / regulatory T cell imbalance in rheumatoid arthritis. J Transl Med 2021; 19:392. [PMID: 34530864 PMCID: PMC8444577 DOI: 10.1186/s12967-021-03071-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 09/07/2021] [Indexed: 11/25/2022] Open
Abstract
Background Patients with rheumatoid arthritis (RA) have increased levels of interleukin-18 (IL-18) and decreased levels of IL-18 binding protein (IL-18BP) in the serum and synovial fluid (SF) compared to those in patients with osteoarthritis (OA) or in healthy controls. In this study, we evaluated the effects of IL-18BP on osteoclastogenesis and T cell differentiation in RA in vitro. Methods Serum and SF of patients with RA and OA were collected to compare IL-18 and IL-18BP levels by the enzyme-linked immunosorbent assay. Peripheral blood mononuclear cells (PBMCs) and SF mononuclear cells (SFMCs) of RA patients were cultured under type 17 helper T cell (Th17) polarisation conditions with or without IL-18BP. In addition, PBMCs were cultured in the presence of receptor activator of nuclear factor kappa-Β ligand (RANKL) or IL-17A with or without IL-18BP, and tartrate-resistant acid phosphatase (TRAP) staining and real-time quantitative polymerase chain reaction for expression levels of osteoclast-related genes were performed. Results IL-18 levels were higher in the serum and SF of patients with RA, whereas IL-18BP was lower in the SF of patients with RA than in the control group. Treatment of patients’ PBMCs with IL-18BP decreased the differentiation of CD4+ IL-17A+ and CD4+ RANKL+ T cells, whereas the differentiation of CD4+CD25highFOXP3+ T cell population increased in a dose-dependent manner. These changes in CD4+ T cell differentiation were also observed in the SFMCs of patients with RA. The levels IL-17A and soluble RANKL in the culture medium were significantly decreased by IL-18BP. IL-18BP administration decreased TRAP+ cell counts in a dose-dependent manner on the background of stimulation with RANKL-and IL-17A. In addition, expression levels of TRAP, NFATC1, CTSK, and TNFRSF11A (RANK) genes were lower in the IL-18BP treated cells. Conclusion We showed that IL-18BP can rectify the Th17/Treg imbalance and decrease IL-17-induced osteoclastogenesis in PBMCs from patients with RA. Therefore, IL-18BP may have therapeutic potential for RA treatment. Supplementary Information The online version contains supplementary material available at 10.1186/s12967-021-03071-2.

Abstract
BACKGROUND This international, randomized, double-blind phase III study (ONO-4538-52/TASUKI-52) evaluated nivolumab with bevacizumab and cytotoxic chemotherapy as first-line treatment for nonsquamous non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Between June 2017 and July 2019, this study enrolled treatment-naïve patients with stage IIIB/IV or recurrent nonsquamous NSCLC without sensitizing EGFR, ALK, or ROS1 alterations. They were randomly assigned in a 1 : 1 ratio to receive nivolumab or placebo in combination with carboplatin, paclitaxel, and bevacizumab every 3 weeks for up to six cycles, followed by nivolumab/placebo with bevacizumab until progressive disease or unacceptable toxicity. The primary endpoint was progression-free survival (PFS) assessed by an independent radiology review committee (IRRC). RESULTS Overall, 550 patients from Japan, Korea, and Taiwan were randomized; of these patients, 273 and 275 received the nivolumab and placebo combinations, respectively. In the present preplanned interim analysis with a median follow up of 13.7 months, the IRRC-assessed median PFS was significantly longer in the nivolumab arm than in the placebo arm (12.1 versus 8.1 months; hazard ratio 0.56; 96.4% confidence interval 0.43-0.71; P < 0.0001). The PFS benefit was observed across all patients with any programmed death-ligand 1 (PD-L1) expression levels including PD-L1-negative patients. The IRRC-assessed objective response rates were 61.5% and 50.5% in the nivolumab and placebo arms, respectively. The incidence of treatment-related adverse events of grade 3 or 4 was comparable between the two arms; treatment-related adverse events leading to death were observed in five and four patients in the nivolumab and placebo arms, respectively. CONCLUSION The TASUKI-52 regimen should be considered a viable new treatment strategy for treatment-naïve patients with advanced nonsquamous NSCLC.

Abstract
BACKGROUND AND PURPOSE Comparison of the diagnostic performance for thyroid cancer on ultrasound between a convolutional neural network and visual assessment by radiologists has been inconsistent. Thus, we aimed to evaluate the diagnostic performance of the convolutional neural network compared with the American College of Radiology Thyroid Imaging Reporting and Data System (TI-RADS) for the diagnosis of thyroid cancer using ultrasound images. MATERIALS AND METHODS From March 2019 to September 2019, seven hundred sixty thyroid nodules (≥10 mm) in 757 patients were diagnosed as benign or malignant through fine-needle aspiration, core needle biopsy, or an operation. Experienced radiologists assessed the sonographic descriptors of the nodules, and 1 of 5 American College of Radiology TI-RADS categories was assigned. The convolutional neural network provided malignancy risk percentages for nodules based on sonographic images. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were calculated with cutoff values using the Youden index and compared between the convolutional neural network and the American College of Radiology TI-RADS. Areas under the receiver operating characteristic curve were also compared. RESULTS Of 760 nodules, 176 (23.2%) were malignant. At an optimal threshold derived from the Youden index, sensitivity and negative predictive values were higher with the convolutional neural network than with the American College of Radiology TI-RADS (81.8% versus 73.9%, P = .009; 94.0% versus 92.2%, P = .046). Specificity, accuracy, and positive predictive values were lower with the convolutional neural network than with the American College of Radiology TI-RADS (86.1% versus 93.7%, P < .001; 85.1% versus 89.1%, P = .003; and 64.0% versus 77.8%, P < .001). The area under the curve of the convolutional neural network was higher than that of the American College of Radiology TI-RADS (0.917 versus 0.891, P = .017). CONCLUSIONS The convolutional neural network provided diagnostic performance comparable with that of the American College of Radiology TI-RADS categories assigned by experienced radiologists.

Abstract
Interstitial pneumonia with autoimmune feature (IPAF) is a recently established disease entity that is comprised of interstitial lung diseases with evidence of autoimmune features but that does not fulfill the criteria for definite autoimmune rheumatic diseases. The classification criteria for IPAF were defined by the European Respiratory Society and American Thoracic Society in 2015. However, further studies to establish IPAF subgroups and treatment modalities for each subgroup are still needed. In this review, we discuss recent advances regarding IPAF and raise critical points for the diagnosis and management of patients with IPAF from the perspective of rheumatologists.

Abstract
Background In the pathogenesis of rheumatoid arthritis (RA), the role of mast cells has not been revealed clearly. We aimed to define the inflammatory and tissue-destructive roles of mast cells in rheumatoid arthritis (RA). Methods Serum and synovial fluid (SF) concentration levels of tryptase, chymase, and histamine were quantified using ELISA. After activating mast cells using IL-33, the production of TNF-α, IL-1β, IL-6, IL-17, RANKL, and MMPs was determined using real-time PCR and ELISA. Osteoclastogenesis was assessed in CD14+ monocytes from peripheral blood and SF, which were cultured with IL-33-activated mast cells, by counting TRAP-positive multinucleated cells. Results The concentration levels of serum tryptase, chymase, and histamine and SF histamine were higher in patients with RA than in controls. FcεR1 and c-kit-positive mast cells were higher in RA synovium than in osteoarthritic (OA) synovium. Stimulation of mast cells by IL-33 increased the number of trypatse+chymase− and tryptase+chymase+ mast cells. IL-33 stimulation also increased the gene expression levels of TNF-α, IL-1β, IL-6, IL-17, RANKL, and MMP-9 in mast cells. Furthermore, IL-33 stimulated human CD14+ monocytes to differentiate into TRAP+ multinucleated osteoclasts. When CD14+ monocytes were co-cultured with mast cells, osteoclast differentiation was increased. Additionally, IL-33-activated mast cells stimulated osteoclast differentiation. The inhibition of intercellular contact between mast cells and monocytes using inserts reduced osteoclast differentiation. Conclusions IL-33 increased inflammatory and tissue-destructive cytokines by activation of mast cells. Mast cells stimulated osteoclast differentiation in monocytes. Mast cells could stimulate osteoclastogenesis indirectly through production of tissue-destructive cytokines and directly through stimulation of osteoclast precursors.

Abstract
OBJECTIVES The choice of second-line biologics for ankylosing spondylitis (AS) patients previously treated with a tumour necrosis factor inhibitor (TNFi) remains unclear. Here, we compared drug retention and clinical efficacy between AS patients who switched biologics to secukinumab and those who switched to a different TNFi. METHODS AS patients enrolled in the Korean College of Rheumatology BIOlogics registry were included, and patients with non-radiographic axial spondyloarthritis were excluded. Patients with previous TNFi exposure were divided into the secukinumab group and the TNFi switching group. Drug retention and clinical efficacy (BASDAI50, ASAS20, ASAS40, ASDAS <2.1, ASDAS clinically important improvement, and ASDAS major improvement) were assessed at the 1 year follow-up. Propensity score (PS)-matched and covariate-adjusted logistic regression analyses were performed. RESULTS 246 had available 1 year follow-up data. Secukinumab as third- or later-line biologics was more frequent than alternative TNFi (54% vs 14%). PS-matched and multiple covariate-adjusted analyses showed that the odds ratio (OR) for drug discontinuation was comparable between the secukinumab and TNFi switching groups (OR = 1.136; 95% CI, 0.843-1.531 and OR = 1.000; 95% CI, 0.433-2.308, respectively). The proportion of patients who achieved BASDAI50 was also comparable between the two groups (OR = 0.833; 95% CI, 0.481-1.441 in PS-matched analysis). Other clinical efficacy parameters were also comparable. In the subgroup analysis of AS patients with previous TNFi discontinuation due to ineffectiveness, all clinical efficacy parameters were comparable between the two groups. CONCLUSION In AS patients with previous exposure to a TNFi, switching biologics to secukinumab and switching to an alternative TNFi resulted in comparable drug retention and clinical efficacy.

Abstract
Alzheimer's disease (AD) shows various symptoms that reflect cognitive impairment and loss of neural circuit integrity. Sensory dysfunctions such as olfactory and ocular pathology are also observed and used as indicators for early detection of AD. Although mastication is suggested to correlate with AD progression, changes in the masticatory system have yet to be established in transgenic animal models of AD. In the present study, we have assessed pathologic hallmarks of AD with the masticatory behavior of 5XFAD mice. We found that masticatory efficiency and maximum biting force were decreased in 5XFAD mice, with no significant change in general motor function. Immunohistochemical analysis revealed significant accumulation of Aβ (amyloid β), increased microglia number, and cell death in Vmo (trigeminal motor nucleus) as compared with other cranial motor nuclei that innervate the orofacial region. Masseter muscle weight and muscle fiber size were also decreased in 5XFAD mice. Taken together, our results demonstrate that Aβ accumulation in Vmo contributes to masticatory dysfunction in 5XFAD mice, suggesting a close association between masticatory dysfunction and dementia.

Abstract
BACKGROUND/AIMS The present study aimed to investigate whether tocotrienol regulates interleukin 17 (IL-17)-induced osteoclastogenesis in rheumatoid arthritis (RA). METHODS We evaluated the effect of tocotrienol on IL-17-induced receptor activator of nuclear factor kappa B ligand (RANKL) production using RA fibroblast-like synoviocyte (FLS), together with real-time polymerase chain reaction and enzyme-linked immunosorbent assay. Osteoclast differentiation was confirmed after culturing IL-17-treated RA FLS and Th17 cells with tocotrienol and monocytes. We analyzed the suppressive effect of tocotrienol on Th17 cells percentage or Th17-cytokine levels among peripheral blood mononuclear cells using flow cytometry. RESULTS We found that IL-17 stimulated FLS to produce RANKL and tocotrienol decreased this IL-17-induced RANKL production. Tocotrienol decreased the IL-17-induced activation of mammalian target of rapamycin, extracellular signal-regulated kinase, and inhibitor of kappa B-alpha. When monocytes were incubated with IL-17, RANKL, IL-17-treated FLS or Th17 cells, osteoclasts were differentiated and tocotrienol decreased this osteoclast differentiation. Tocotrienol reduced Th17 cell differentiation and the production of IL-17 and sRANKL; however, tocotrienol did not affect Treg cell differentiation. CONCLUSION Tocotrienol inhibited IL-17- activated RANKL production in RA FLS and IL-17-activated osteoclast formation. In addition, tocotrienol reduced Th17 differentiation. Therefore, tocotrienol could be a new therapeutic choice to treat bone destructive processes in RA.

Abstract
OBJECTIVE This study aimed to evaluate the impact of biologic disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) on lipid profile and atherogenic index of plasma (AIP) in rheumatoid arthritis (RA) patients and to compare the occurrence of dyslipidemia between patients using bDMARDs, tsDMARDs, or conventional DMARDs (cDMARDs). METHODS Data on lipid profile, AIP, and occurrence of dyslipidemia were collected from the Korean College of Rheumatology BIOlogics registry. A comparison was conducted between patients using bDMARDs (tumor necrosis factor (TNF)-α inhibitor, tocilizumab, abatacept), Janus kinase inhibitors (JAKis), and cDMARDs. The Kaplan-Meier method was used to compare the occurrence of dyslipidemia between groups, and hazard ratios (HR) were calculated using the cox proportional hazard method. RESULTS The data of 917, 826, 789, 691, and 520 RA patients were eligible for analysis at the baseline, 1-year, 2-year, 3-year, and 4-year follow-ups, respectively. Baseline total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) were higher in the cDMARDs group, whereas AIP was comparable. During the 4-year follow-up, AIP was comparable between the groups. The occurrence of dyslipidemia did not show a significant difference when comparing the bDMARDs/tsDMARDs and cDMARDs groups (P=0.06) or the TNF-α inhibitor, tocilizumab, abatacept, JAKi, and cDMARD user groups (P=0.3). In the multivariate cox proportional hazard model, older age (HR=1.03, P=0.005) and concomitant hypertension (HR=2.21, P=0.013) were significantly associated with dyslipidemia occurrence. CONCLUSION Long-term use of bDMARDs and tsDMARDs is relatively safe with regard to lipid profile, AIP, and the occurrence of dyslipidemia in RA patients. Key Points • The use of bDMARDs and tsDMARDs did not increase the risk of dyslipidemia than cDMARDs use in patients with RA. • AIP was comparable between bDMARDs user, tsDMARDs user, and cDMARDs user group in 4-year follow-up data. • Based on the present study, the long-term use of bDMARDs or tsDMARDs did not significantly deteriorate atherogenic lipid profile nor an increased risk of dyslipidemia in patients with RA.

Abstract
OBJECTIVE To assess the clinical, laboratory, and salivary gland ultrasound (SGUS) characteristics of elderly-onset of primary Sjögren's syndrome (EopSS). METHODS We included pSS patient from two referral hospitals over a 4-year period. The SGUS scores (0-48) and SG volumes were assessed. Clinical, laboratory, and SGUS data were compared according to age at onset: EopSS (≥65 years), adult-onset (AopSS) (≥40 and <65 years), and young-onset (YopSS) (<40 years). RESULTS This cross-sectional study included a total of 221 patients, 43 (19.5%) of which had EopSS. Subjective sicca symptoms, results of the Schirmer's test, and unstimulated salivary flow rate revealed no significant differences between the groups. EopSS patients presented a significantly higher frequency of interstitial lung disease (ILD) (EopSS: 51.2% vs. AopSS: 13.5% vs. YopSS: 8.7%, P<0.001) and lower frequency of arthritis (7% vs. 22.6% vs. 39.1%, P<0.01). They also had significantly lower positivity of anti-Ro/SSA (51.2%) and anti-La/SSB (7.0%) and lower levels of rheumatoid factor, C4, and IgG. The EopSS group had significantly lower SGUS positivity (defined as total scores ≥14) (44.2% vs. 64.5% vs. 78.3%, P<0.05), lower SGUS scores, and smaller submandibular gland volume. CONCLUSION We report a specific phenotype of EopSS, characterised by high prevalence of ILD, less involvement of the peripheral joint, and low biological activity. SGUS evaluation showed less parenchymal abnormalities but more atrophic changes in major SGs in EopSS patients. Considering the low positivity of anti-Ro/SSA and SGUS in EopSS, SG biopsy remains the only way to confirm the diagnosis of pSS, especially in elderly patients.

Abstract
Chronic shoulder pain is a common complication in breast cancer patients after surgery. Chronic shoulder pain after breast cancer surgery was formerly considered as neuropathic pain, however the pathophysiology including structural damages has not been assessed comprehensively. We hypothesized that the structural change could be one of the cause of shoulder pain after breast cancer surgery and evaluated various ultrasonography findings of the shoulder in breast cancer patients with chronic shoulder pain. Patients who were suffering from chronic shoulder pain on unilateral side for at least 3 months after breast cancer surgery were enrolled from a single tertiary hospital. Demographic and clinical data were collected at the baseline. Articular and adjacent structures of both shoulders (painful and contralateral side) were evaluated by ultrasonography. The ultrasonography findings were compared between painful and contralateral sides. Logistic regression analysis was performed to determine the factors associated with abnormal ultrasonography findings. Fifty-two female patients (average age of 55) were enrolled. Significantly more abnormal ultrasonography findings were observed in the painful side than in the contralateral side [39 (75.0%) vs 11 (21.2%), P < 0.001]. The coracohumeral ligament was significantly thicker in the painful side than in the contralateral side (2.48 ± 0.69 vs 1.54 ± 1.25 mm, P < 0.001); adhesive capsulitis was also more frequent in the painful side [14 (26.9%) vs 0, P < 0.001]. Furthermore, patients with a history of breast cancer surgery on the ipsilateral side were associated with abnormal ultrasonography findings and adhesive capsulitis. This study is the first to evaluate ultrasonography in patients with chronic shoulder pain after breast cancer surgery. The results showed that ultrasonography could reveal several structural problems in these patients.

Abstract
BACKGROUND The present study aimed to evaluate the suppressive role of interleukin (IL)-25 in IL-22-induced osteoclastogenesis and receptor activator of nuclear factor κB ligand (RANKL) expression in rheumatoid arthritis (RA). METHODS Serum from patients with RA and osteoarthritis (OA), and healthy controls, and synovial fluid from patients with RA and OA were collected, and the levels of IL-22 and IL-25 were measured. RA and OA synovial tissues were stained against IL-25. Fibroblast-like synoviocytes (FLSs) of patients with RA were cultured with IL-22, in the presence or absence of IL-25, and RANKL expression was measured by real-time PCR and enzyme-linked immunosorbent assay (ELISA). Human peripheral blood monocytes were cultured under IL-22/RANKL + M-CSF, with or without IL-25, and tartrate-resistant acid phosphatase (TRAP)-positive cells and osteoclast-related markers were investigated to determine osteoclastogenesis. RESULTS Serum and synovial IL-25 levels in RA were upregulated compared to those in OA and healthy control, and elevated expression of IL-25 in RA synovial tissue was re-confirmed. IL-25 and IL-22 levels showed significant correlation in serum and synovial fluid. Pre-treatment of FLS with IL-25 reduced IL-22-induced RANKL expression at the RNA level. The suppressive effects of IL-25 were confirmed to occur through the STAT3 and p38 MAPK/IκBα pathways. IL-25 reduced osteoclast differentiation and suppressed the expression of osteoclast-related markers. CONCLUSION In the current study, we demonstrated the regulatory effect of IL-25 on IL-22-induced osteoclastogenesis. Therapeutic approach involving augmentation of IL-25 regulatory response may serve as a novel treatment option for RA, especially by suppressing osteoclastogenesis.

Abstract
AIM This prospective study aimed to evaluate the diagnostic performance of the 2012 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for polymyalgia rheumatica (PMR) compared to that of previous classification/diagnostic criteria in the Korean population. METHOD We consecutively included 77 patients aged ≥50 years presenting with bilateral shoulder pain and elevated acute-phase reactants. All patients were evaluated for fulfillment of each of the 5 different criteria for PMR (Chuang et al, Bird, Jones and Hazleman, Healey, and the EULAR/ACR criteria). At baseline, bilateral ultrasound (US) examinations of the shoulders and hips were performed. Final diagnosis was made by an experienced rheumatologist at the 12-month follow-up. The area under the curve (AUC), sensitivity, and specificity of criteria sets were assessed. RESULTS At the end of follow-up, 38 and 39 patients were diagnosed with PMR and non-PMR including rheumatoid arthritis (RA, n = 20), respectively. The EULAR/ACR classification criteria with US showed the best discriminating capacity (AUC 0.843). Adding US to EULAR/ACR criteria increased specificity from 74.4% to 89.7%, but decreased sensitivity from 89.5% to 78.9%. The two US items of the EULAR/ACR criteria were significantly more frequent in patients with PMR than in controls. However, the second criterion consisting of both shoulders inflamed were similar between PMR (60.5%) and RA (60.0%) groups. CONCLUSION The 2012 EULAR/ACR classification criteria for PMR performed best in classifying PMR from other inflammatory and non-inflammatory disorders with shoulder pain in Asian populations.

Abstract
BACKGROUND Aortoiliac calcification may be a surrogate marker of decreased visceral perfusion causing anastomotic leak (AL). The aim of this study was to evaluate the predictive role of aortoiliac calcification for AL after rectal cancer surgery. METHODS We enrolled patients with primary rectal cancer who had restorative resection at our institution between January 2013 and December 2015. An aortoiliac calcification score was calculated as the sum of calcification scores at the infrarenal aorta (0: no, 1: ≤ 3 cm, 2: > 3 cm) and the common iliac arteries (0: no, 1: unilateral, 2: bilateral). AL was classified into three grades: grade A, requiring no intervention; grade B, requiring therapeutic intervention without re-laparotomy; and grade C, requiring re-laparotomy. Clinicopathological characteristics were analyzed to identify risk factors for AL. RESULTS There were 583 patients. Three-hundred forty-five (59.2%) had an aortoiliac calcification score ≥ 3, and 37 (6.3%) patients experienced AL, in 30 cases (5.1%) grade C AL. Patients with an aortoiliac calcification score ≥ 3 had a higher incidence of grade C AL (6.7% vs. 2.9%, p = 0.045). Multivariate logistic regression analysis revealed that an aortoiliac calcification score ≥ 3 was an independent risk factor for grade C AL (odds ratio = 2.669, 95% confidence interval 1.066-6.686, p = 0.036). CONCLUSIONS Aortoiliac calcification may be considered a risk factor for grade C AL after rectal cancer surgery.

Comparative outcomes of robot-assisted minimally invasive versus open esophagectomy in patients with esophageal squamous cell carcinoma: a propensity score-weighted analysis.

Abstract
Robots are increasingly used in minimally invasive surgery. We evaluated the clinical benefits of robot-assisted minimally invasive esophagectomy (RAMIE) in comparison with the conventional open esophageal surgery. From 2012 to 2016, 371 patients with esophageal squamous cell carcinoma underwent an Ivor Lewis or McKeown procedure at our institution. Of these, 130 patients underwent laparoscopic gastric conduit formation followed by RAMIE, whereas 241 patients underwent conventional esophageal surgery, including laparotomy and open esophagectomy (OE). We compared the short- and long-term clinical outcomes of these patients using the propensity score-based inverse probability of treatment weighting technique (IPTW). Among the early outcomes, the OE group showed a higher incidence of pneumonia (P = 0.035) and a higher requirement for vasopressors (P = 0.001). Regarding the long-term outcomes, all-cause mortality was significantly higher (P = 0.001) and disease-free survival was lower (P = 0.006) in the OE group. Wound-related problems also occurred more frequently in the OE group (P = 0.020) during the long-term follow-up. There was no statistical intergroup difference in the recurrence rates (P = 0.191). The Cox proportional-hazard analysis demonstrated that wound problems (HR 0.16, 95% CI 0.02-0.57; P = 0.017), pneumonia (HR 0.23, 95% CI 0.06-0.68; P = 0.019), and use of vasopressors (HR 0.14, 95% CI 0.08-0.25; P = 0.001) were independent predictors of mortality. RAMIE could be a better surgical option for selected patients with esophageal squamous cell carcinoma.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory arthritis, and the complex interaction and activation of innate and adaptive immune cells are involved in RA pathogenesis. Mast cells (MCs) are one of the tissue-resident innate immune cells, and they contribute to RA pathogenesis. In the present review, the evidence of the pathologic role of MC in RA is discussed based on human and animal data. In addition, the potential role of MC in RA pathogenesis and the research area that should be focused on in the future are suggested.

Background
prediction of outcomes Hypertrophic cardiomyopathy (HCM) have been robustly analyzed with echocardiography. However, there is limited data of serial follow-up (FU) transthoracic echocardiography (TTE) to predict outcomes in patients with HCM.
Objectives
This study aim is to discover clinical predictors associated with consecutive TTE follow-up in patients with HCM.
Methods
From 2010 to 2016, 162 patients with HCM were enrolled retrospectively. Concentric LVH and others systolic disease related to wall thickness were excluded. Index TTE (baseline) was measured when firstly admitted in our hospital. FU TTE was analyzed at the end of follow-up, defined as the last recorded value in patients who did not develop events or the last recorded value before events developed.
Results
The average of FU TTE and clinical FU period was 3.7 ± 2.0 years. Clinical outcomes were defined as stroke, syncope, heart failure, arrhythmia and death. Interestingly, only baseline TR V max was a predictor for clinical outcome whereas the others echo parameters were not associated with events (Table 1). KM curve showed the TR Vmax ≥2.5m/s was also significant (log rank = 0.008, Fig 1.)
Conclusions Our study showed short-term FU TTE did not bring clinician with clinical benefits in the aspect of prediction for events. Only baseline TR V max was good correlation with cardiovascular outcomes and even in the survival analysis.
