Intra-Abdominal Epithelioid Neoplasm With EWSR1::CREB Fusions Involving the Kidney: A Clinicopathologic and Molecular Characterization With an Emphasis on Differential Diagnosis. Mod Pathol 2024; 37:100468. [PMID: 38460673 DOI: 10.1016/j.modpat.2024.100468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 02/19/2024] [Accepted: 03/01/2024] [Indexed: 03/11/2024]
Abstract
Soft tissue neoplasms, harboring fusions between EWSR1 and FUS with genes encoding CREB transcription factors family (ATF1, CREB1, and CREM), are an emerging heterogeneous group of mesenchymal tumors that differ significantly in morphology, immunophenotypes, and behavior. Recently, EWSR1/FUS::CREB fusions have been recognized to define a group of aggressive neoplasms of epithelioid morphology with multiple growth patterns and a striking predilection for mesothelial-lined cavities. These neoplasms presenting as a primary neoplasm of intra-abdominal visceral organs are rare, which could elicit a wide range of differential diagnoses because of their diverse morphologies and immunohistochemical profiles. We report 3 cases of intra-abdominal epithelioid neoplasms with EWSR1::CREB fusions involving the kidney. This study included 2 female patients and 1 male patient, with age at presentation ranging from 17 to 61 years (mean: 32 years). All the patients underwent radical nephrectomy without adjunctive therapies. Grossly, the tumors were large, and all were solitary masses with sizes ranging from 5.6 to 30.0 cm (mean: 14.5 cm). Histologically, the neoplasms showed infiltrating and indistinct borders and were composed predominantly of monomorphic round-to-epithelioid cells with variable amounts of pale-to-clear cytoplasm, arranged in cords, nests, and sheets and embedded in a sclerotic hyalinized stroma with variable lymphoid cuffing either intermixed or at the periphery. Notably, a hemangiopericytomatous growth pattern was commonly seen. Nuclear atypia was mild, and mitotic activity was scarce. Immunohistochemically, all 3 cases were at least focally positive for epithelial membrane antigen and keratin AE1/AE3, with 2 tumors showing focal MUC4 expression and 1 case displaying diffuse CD34 and focal CAIX positivity. Targeted RNA sequencing identified EWSR1::CREM fusion in 2 cases and EWSR1::ATF1 fusion in 1 case. Subsequent fluorescence in situ hybridization analysis confirmed the RNA sequencing results. On follow-up, 1 patient developed multiple spinal bone metastases 5 months after the surgery while the other 2 patients were free of disease 9 and 120 months after diagnosis, respectively. Our findings demonstrate that intra-abdominal epithelioid neoplasms with EWSR1::CREB fusions may rarely occur primarily in the kidney and should be included in the differential diagnosis of primary renal epithelioid mesenchymal neoplasms.

Abstract
We report the first measurement of discrimination between low-energy helium recoils and electron recoils in liquid xenon. This result is relevant to proposed low-mass dark matter searches which seek to dissolve light target nuclei in the active volume of liquid-xenon time projection chambers. Low-energy helium recoils were produced by degrading α particles from ^{210}Po with a gold foil situated on the cathode of a liquid xenon time-projection chamber. The resulting population of helium recoil events is well separated from electron recoils and is also offset from the expected position of xenon nuclear recoil events.

Abstract
BACKGROUND Cancer survivors are at increased risk for cardiovascular (CV) disease, although additional data are needed to better understand the incidence of CV events across different malignancies. This study sought to characterize the incidence of major adverse CV events [myocardial infarction, stroke, unstable angina (MACE), or heart failure (HF)] across multiple cancer types after cancer diagnosis. PATIENTS AND METHODS Patients were identified from a USA-based administrative claims database who had index cancer diagnoses of breast, lung, prostate, melanoma, myeloma, kidney, colorectal, leukemia, or lymphoma between 2011 and 2019, with continuous enrollment for ≥12 months before diagnosis. Baseline CV risk factors and incidence rates of CV events post-index were identified for each cancer. Multivariable Cox hazards models assessed the cumulative incidence of MACE, accounting for baseline risk factors. RESULTS Among 839 934 patients across nine cancer types, CV risk factors were prevalent. The cumulative incidence of MACE was highest in lung cancer and myeloma, and lowest in breast cancer, prostate cancer, and melanoma. MACE cumulative incidence for lung cancer was 26% by 4 years (2.7-fold higher relative to breast cancer). The incidence of stroke was especially pronounced in lung cancer, while HF was highest in myeloma and lung cancer. CONCLUSIONS CV events were especially increased following certain cancer diagnoses, even after accounting for baseline risk factors. Understanding the variable patient characteristics and associated CV events across different cancers can help target appropriate CV risk factor modification and develop strategies to minimize adverse CV events and improve patient outcomes.

Abstract
Objective Existing evidence suggests that palliative care (PC) is highly underutilized in metastatic gynecologic cancer (mGCa). This study aims to explore temporal trends and predictors for inpatient PC referral in mGCa patients who received specific critical care therapies (CCT). Methods The National Inpatient Sample from 2003 to 2015 was used to identify mGCa patients receiving CCT. Basic characteristics were compared between patients with and without PC. Annual percentage change (APC) was estimated to reflect the temporal trend in the entire cohort and subgroups. Multivariable logistic regression was employed to explore potential predictors of inpatient PC referral. Results In total, 122,981 mGCa patients were identified, of whom 10,380 received CCT. Among these, 1,208 (11.64%) received inpatient PC. Overall, the rate of PC referral increased from 1.81% in 2003 to 26.30% in 2015 (APC: 29.08%). A higher increase in PC usage was found in white patients (APC: 30.81%), medium-sized hospitals (APC: 31.43%), the Midwest region (APC: 33.84%), and among patients with ovarian cancer (APC: 31.35%). Multivariable analysis suggested that medium bedsize, large bedsize, Midwest region, West region, uterine cancer and cervical cancer were related to increased PC use, while metastatic sites from lymph nodes and genital organs were related to lower PC referral. Conclusion Further studies are warranted to better illustrate the barriers for PC and finally improve the delivery of optimal end-of-life care for mGCa patients who receive inpatient CCT, especially for those diagnosed with ovarian cancer or admitted to small scale and Northeast hospitals.

Abstract
PURPOSE Lung cancer (LC) is a common malignancy worldwide. A great number of circular RNAs (circRNAs) have been identified that serve crucial roles in cancer development. Extracellular vesicles (EVs) and their contents have been shown to be biomarkers for the diagnosis and prognosis of LC. Thus, we intended to clarify the functional role of EVs-derived circRNA homology domain interacting protein kinase 3 (EVs-circHIPK3) and its underlying mechanism of action. MATERIAL AND METHODS Bioinformatics analysis was performed to validate the potential of partially circulating HIPK3 in LC diagnosis. EVs were isolated by polyethylene glycol (PEG) precipitation from plasma of 52 LC patients and 30 healthy controls. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was employed to evaluate the expressions of candidate circRNAs (circHIPK3) and microRNA-637 (miR-637, a target of circHIPK3). RESULTS CircHIPK3 is significantly up-regulated in LC, while miR-637 expression is significantly reduced (p < 0.05). Receiver operating characteristic (ROC) curve analysis, based on the expression of EVs-circHIPK3, allowed us to distinguish LC from healthy controls (area under the curve, AUC 0.897). CONCLUSIONS Taken together, our study shows that EV-derived circHIPK3 can serve as a promising biomarker for LC patient diagnosis. However, the downstream mRNA of the circHIPK3/miR-637 axis requires further exploration to enrich our understanding of circHIPK3's mechanism in LC.

Abstract
The LUX-ZEPLIN experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LUX-ZEPLIN's first search for weakly interacting massive particles (WIMPs) with an exposure of 60 live days using a fiducial mass of 5.5 t. A profile-likelihood ratio analysis shows the data to be consistent with a background-only hypothesis, setting new limits on spin-independent WIMP-nucleon, spin-dependent WIMP-neutron, and spin-dependent WIMP-proton cross sections for WIMP masses above 9 GeV/c^{2}. The most stringent limit is set for spin-independent scattering at 36 GeV/c^{2}, rejecting cross sections above 9.2×10^{-48} cm at the 90% confidence level.

Abstract
Multiple primary malignancies combined with SWI/SNF complex-deficient gastric cancer is a rare clinical entity and poorly documented. Herein we report a case of this disease in an 81-year-old male patient treated in our hospital. Before the established diagnosis of metachronous multiple primary malignancies, the patient received left lower lobectomy for a spaceoccupying mass in the left lung, which was confirmed by postoperative pathology as early stage lung cancer. SWI/SNF complex-deficiency gastric cancer with metastasis was subsequently detected by gastroscopy, and high-throughput sequencing identified ARID1A and TMB-H gene mutations in the tumor tissues. The patient received chemotherapy combined with immunotherapy but failed to respond to the treatment, and died 13 months later. We conducted a literature review and analyzed the occurrence, pathological and immunohistochemical characteristics, diagnosis, treatment and prognosis of this disease.

Abstract
Objective: The susceptibility of tinnitus rats with low estrogen level induced by sodium salicylate and the changes of tumor necrosis factor α (TNF-α) in serum were observed to investigate the relationship between tinnitus occurrence and estrogen level. Methods: Forty-two healthy female Wistar rats were randomly divided into control group(n=6), normal group(n=6), sham operation group(n=6) and ovariectomized group(n=24). Control group was intraperitoneally injected with normal saline 200 mg/kg for 14 consecutive days. Normal group, sham operation group and ovariectomized group were intraperitoneally injected with sodium salicylate 200 mg/kg for 14 consecutive days. Before and after sodium salicylate induction, the tinnitus behavior of rats in each group was detected by prepulse inhibition (PPI) and gap pre-pulse inhibition of the acoustic startle (GPIAS) test. Before and after sodium salicylate induction, blood samples were collected from eyeballs of rats in each group, and serum levels of estradiol and TNF-α were detected by ELISA. SPSS 25.0 software was used to analyze the data. Results: (1) Following 14 days of sodium salicylate intervention, there was no significant difference in PPI inhibition rate between groups or within groups(all P>0.05). (2)There was no significant difference in the inhibition rate of GPIAS in the four groups before sodium salicylate injection(F=0.217, P>0.05). With sodium salicylate injected for 14 days, the inhibition rate of GPIAS in ovariectomized group (30.88%±15.40%) was significantly lower than that in the other three groups (44.11%±21.06%, 38.27%±10.92%, 51.59%±11.34%), and the difference was statistically significant(F=3.533, P<0.05). The inhibition rate of GPIAS in ovariectomized group with sodium salicylate injected for 14 days was significantly lower than that before injection, and the difference was statistically significant(t=2.977, P<0.05).There was no significant difference in GPIAS inhibition rate between the other three groups before and after sodium salicylate injection(P>0.05). (3)The level of TNF-α in ovariectomized rats was significantly higher than that in the other three groups, the difference was statistically significant(all P<0.05). With sodium salicylate injection for 14 days, TNF-α level in the ovariectomized group increased more significantly than that in the other three groups, the difference was statistically significant(F=8.045, P<0.05). TNF-α levels increased following salicylate injection in normal group, sham operation group and ovariectomized group, and the differences were statistically significant(t value was -4.843, -4.932 and -5.965 respectively, each P<0.05). There was no significant difference in TNF-α levels before and after normal saline injection in control group(all P>0.05). Conclusion: Low estrogen levels increase susceptibility to sodium salicylate-induced tinnitus. Decreased estrogen levels may increase susceptibility to tinnitus through the increased expression of pro-inflammatory factor TNF-α.

Abstract
BackgroundPsoriatic arthritis (PsA) is a complex inflammatory disease with manifestations that play an important role in treatment selection.1 Treatments include oral agents, biologic therapies (inhibitors of tumor necrosis factor [TNFi], interleukin [IL-17Ai, IL-12/23i], cytotoxic T lymphocyte–associated antigen 4 inhibitor [CTLA-4i]), and new targeted oral agents (inhibitors of phosphodiesterase-4 [PDE-4i] and Janus kinase [JAKi]).1 Few studies have examined real-world treatment patterns of recently approved therapies.ObjectivesEvaluate real-world treatment patterns for branded systemic therapy in patients with PsA.MethodsIn this retrospective study, medical and pharmacy claims from the US IBM MarketScan Commercial and Medicare databases (1/1/2012–12/31/2019) were used to identify patients with PsA who initiated treatment with a TNFi (adalimumab, etanercept, infliximab, golimumab, or certolizumab), IL-17Ai (secukinumab, ixekizumab), IL-12/23p40i (ustekinumab), IL-23p19i (guselkumab), CTLA-4i (abatacept), JAKi (tofacitinib), or PDE-4i (apremilast). Patients (≥18 years) with ≥1 prescription, ≥2 PsA claims separated by ≥1 day on or before the index date (first prescription date [1/1/13–12/31/2018]), and 1-year continuous enrollment before and after the index date were eligible. Treatment patterns were grouped into continuers, discontinuers, and patients with treatment modification (switchers [without a treatment gap], reinitiators [same drug with a treatment gap], and restarters [different drug with a treatment gap]) (Table 1). Patients were followed for 1 year or until treatment modification, whichever came first. Descriptive statistics were used.Table 1.TerminologyCohortDefinitionn/N (%)ContinuersOn index treatment during 1-year follow-up with no treatment gaps*1910/6455 (29.6)DiscontinuersNo prescription claims for any therapy during 1-year follow-up1614/6455 (25.0)Patients with treatment modificationsAll patients with a change in treatment during 1-year follow-up2908/6455 (45.1)SwitchersPrescription claims for treatments different than index therapy before permissible treatment gaps*794/6455 (12.3)ReinitiatorsPrescription claims for treatments SAME as index therapy AFTER treatment gaps*1686/6455 (26.1)RestartersPrescription claims for DIFFERENT therapy AFTER treatment gap*428/6455 (6.6)Note: All terminology applies to cohorts within the first year of treatment.*Treatment gap: gap of 200% of recommended dosing schedule from end of previous prescription’s days’ supply.ResultsA total of 6455 patients were included (mean age, 50.5 years; 55.5% female; mean Charlson Comorbidity Index score, 0.54). At baseline, the most commonly used therapies were immunosuppressants (58.5%), corticosteroids (52.2%), and nonsteroidal anti-inflammatory drugs (45.9%). Treatments most used at index were TNFi (72.5%; including adalimumab [41.6%] and etanercept [23.8%]) and the PDE-4i apremilast (21.1%). During the 1-year study period, 29.6% of patients maintained their index therapy and 25.0% discontinued. Treatment modification was observed in 45.1% of patients; 12.3% switched to a new therapy without a treatment gap, 26.1% restarted their index therapy, and 6.6% started a new therapy after a treatment gap.ConclusionAmong patients with PsA, there is substantial variability, including high rates of discontinuation within the first year and after index therapy.

Abstract
The development of DNA nanotechnology make it possible to artificially generate complex nucleic acid nanostructures with controllable sizes and shapes. DNA origami emerges as an effective and versatile approach to construct two- and three-dimensional programmable nanostructures, and represents a milestone in the development of structural DNA nanotechnology. Due to its high degree of controllable geometry, spatial addressability, easy chemical modification and good biocompatibility, DNA origami has great potentials for applications in many fields. In this review, we briefly summarize the applications of DNA origami in antigen-antibody interaction, targeted drug delivery and the synthesis of biomaterials.

Abstract
We report on a comparison between the theoretically predicted and experimentally measured spectra of the first-forbidden nonunique β-decay transition ^{137}Xe(7/2^{-})→^{137}Cs(7/2^{+}). The experimental data were acquired by the EXO-200 experiment during a deployment of an AmBe neutron source. The ultralow background environment of EXO-200, together with dedicated source deployment and analysis procedures, allowed for collection of a pure sample of the decays, with an estimated signal to background ratio of more than 99 to 1 in the energy range from 1075 to 4175 keV. In addition to providing a rare and accurate measurement of the first-forbidden nonunique β-decay shape, this work constitutes a novel test of the calculated electron spectral shapes in the context of the reactor antineutrino anomaly and spectral bump.

Abstract
Background:Sjogren’s syndrome (SS) is a chronic progressive autoimmune disorder which occurs as primary (pSS) or secondary SS (sSS). With no approved disease modifying therapy, there is limited information on the treatment patterns and resource utilization among these patients (pts).Objectives:To describe pts characteristics, treatment patterns and healthcare resource utilization (HCRU) using electronic health records (EHR) of pts with pSS and sSS treated at the Providence St. Josephs Health system (PSJH).Methods:Pts ≥18 years of age with at least one clinical encounter with ICD-9-CM or ICD-10-CM diagnosis of SS, between Jan 2013 and Mar 2019 were included. Date of first encounter with SS diagnosis (index date) was used to assess pts demographics. Pt baseline comorbidities were evaluated during the 24 months pre-index period. Treatment patterns and HCRU were assessed during the 12 months post-index follow-up. Descriptive statistics were used to describe pts’ demographic and clinical characteristics, and medications use in the baseline and follow up.Results:Study cohort included 9,108 SS pts of which 76.5% had sSS diagnosis on index date. Majority of SS pts were women, Caucasian, with mean age of 58.3 yrs, and from western states in the US (Table 1). Endocrine conditions including hypo- and hyperthyroidism, and diabetes was the most common (45.5%) comorbidity at baseline, followed by rheumatologic disorders (25.6%) and neurological conditions (22.2%). Among patients with treatment information (4088, 44.88%), 42.95% were using symptomatic treatments for dry eye and mouth at baseline (Table 1). In the follow-up, SS pts had average 5.8 healthcare visits per patient per year (PPPY), including 0.6 inpatient and 3.4 outpatient visit respectively. About 40% of the SS pts (53.8% pSS and 35.8% sSS) were diagnosed by rheumatologists. Majority of the SS pts initiated treatment with cDMARDs (82%) and remained on the same treatment during 1 year follow-up (Fig 2).Table 1.Baseline Demographic and Clinical Pts CharacteristicsSS Pts (n=9,108)DemographicsAge (years) on index date, mean (SD)58.3 (15.1)Female, n (%)8,338 (91.6)Caucasian, n (%)6.936 (76.2)Western Region, n (%)8,998 (98.8)Married, n (%)5,164 (56.7)Never Smoked, n (%)4,847 (53.2)Primary diagnosis, n (%)2,137 (23.5)Comorbidities, n (%)Cardiovascular1,408 (17.2)Endocrine3,733 (45.5)Oncology800 (9.8)Blood disorders1,221 (14.9)Pulmonary1,802 (22.0)Neurological1,821 (22.2)Liver/Kidney1,782 (21.7)Rheumatologic disorders2,096 (25.6)Autoimmune/ Immune related1,527 (18.6)Baseline Medications, n (%)Symptomatic11,756 (43.0)NSAIDs21,578 (38.6)cDMARDs31,435 (35.1)Corticosteroid41,393 (34.1)bDMARDs5266 (6.5)1cevimeline, pilocarpine hydrochloride, ophthalmic insert etc;2aspirin, ibuprofen, naproxen;3methotrexate, hydroxychloroquine, sulfasalazine, leflunomide, myophenolate mofetil, azathioprine;4prednisone;5sarilumab, belimumab, ustekinumab, infliximab, adalimumab, certolizumab pegol, golimumab, etanercept, abatacept, tocilizumab, rituximab, tofacitinib, baricitinibFigure 1.HCRU for pSS and sSS PtsFigure 2.Treatment Sequencing for pSS and sSS Pts.

Abstract
Background:Rheumatoid arthritis (RA) has been shown a strong genetic association with particularHLA–DRB1alleles containing shared epitope (SE). However, whether SE is clinically useful in treatment choices is insufficiently investigated1and previous studies have presented mixed findings in the role of SE in the response of TNFi therapies2,3.Objectives:To assess the role of SE in response to TNFi treatment in real-world RA patients (pts).Methods:Pts enrolled in a large RA registry, Brigham and Women’s Hospital RA Sequential Study, with known SE and received TNFi therapies were included for the analysis. TNFi pts were identified by the first-time use of the drugs between March 2003 to June 2018. For this analysis, all pts were followed up to 1 year. Summary statistics are reported for demographics, serostatus and disease activity (DA) at baseline and follow-up, stratified by SE status. Given the strong association of SE and anti-citrullinated protein antibody (ACPA), the analysis was further stratified by ACPA status. The effect of SE on change in DA was assessed using linear regression model with age, gender, RA disease duration, baseline DA, smoking status, SE, ACPA and ACPA-SE interaction as covariates.Results:Of the 484 TNFi pts included in the study, 68.8% were SE+. SE+ pts (vs SE-) were more likely to be rheumatoid factor positive, have erosive disease and a higher disease duration, irrespective of ACPA status. No difference in the change of DA was observed by SE. In SE- pts, ACPA+ pts had a greater reduction of DA than ACPA- pts (Table 1). After accounting for baseline differences, there was no significant effect of SE status on the mean change from baseline in any of the 3 DA measures.(Figure 1) The change in DA was not associated with ACPA but was significantly affected by disease duration and baseline DA.Table 1.Disease Activity in TNFi Patients, Stratified by SE and ACPA StatusParameterSE+ (1 & 2 alleles, n=333)SE- (n=151)ACPA+ACPA–OverallACPA+ACPA-Overall(n=264)(n=69)(n=333)(n=90)(n=61)(n=151)Baseline, Mean (SD)DAS28 CRP3.94 (1.69)3.57 (1.61)3.86 (1.67)3.85 (1.49)3.45 (1.65)3.69 (1.57)CDAI23.06 (18.13)18.95 (15.96)22.25 (17.78)21.91 (15.96)17.72 (17.06)20.26 (16.48)SDAI24.08 (18.82)19.96 (16.59)23.27 (18.45)22.58 (16.34)18.55 (17.87)20.99 (17.01)Follow-up, Mean (SD)DAS28 CRP3.42 (1.55)2.69 (1.32)3.27 (1.53)3.19 (1.43)3.11 (1.53)3.16 (1.47)CDAI17.61 (15.53)12.11 (12.65)16.51 (15.14)15.15 (13.35)14.94 (14.73)15.07 (13.84)SDAI18.35 (15.73)12.45 (12.78)17.15 (15.34)15.31 (13.81)15.71 (15.45)15.46 (14.38)Change, Mean (SD)DAS28 CRP-0.48 (1.31)-0.65 (1.53)-0.52 (1.36)-0.52 (1.50)-0.24 (0.93)-0.42 (1.34)CDAI-4.29 (13.16)-4.79 (13.13)-4.39 (13.12)-6.45 (13.56)-2.63 (9.58)-4.99 (12.28)SDAI-4.74 (14.13)-5.07 (13.90)-4.80 (14.05)-6.87 (14.21)-2.97 (10.32)-5.41 (12.98)Figure 1.Linear Regression Model for Change in Disease Activity*Estimates, p-values are shown as data labels on the graphs; The above model is adjusted for age, gender, RA duration, smoking status, SE status, baseline DA, ACPA and ACPA*SE statusConclusion:This real-world study validates the finding from previous studies conducted in clinical settings that SE does not differentiate treatment response for TNFi therapies.References:[1]Saruhan-Direskeneli G, et al.Rheumatology (Oxford) 2007;46(12):1842-44[2]Skapenko A, et al.Clin Exp Rheumatol2019;37(5):783-790[3]Rigby W, et al.Annals of the Rheumatic Diseases2019;78(2):263-264Disclosure of Interests:Joe Zhuo Shareholder of: Bristol-Myers Squibb, Employee of: Bristol-Myers Squibb, Joshua Bryson Shareholder of: I own shares of Bristol-Myers Squibb Company, Employee of: I am a paid employee of Bristol-Myers Squibb Company, Qian Xia Shareholder of: I own shares of Bristol-Myers Squibb Company, Employee of: I am a paid employee of Bristol-Myers Squibb Company, Niyati Sharma Consultant of: I work as a consultant for Bristol-Myers Squibb Company, Chidananda Samal Consultant of: I work as a consultant for Bristol-Myers Squibb Company, Sonie Lama Shareholder of: I own shares of Bristol-Myers Squibb Company., Employee of: I am a paid employee of Bristol-Myers Squibb Company., Michael E.

Abstract
Background:Limited information is available on the impact of target disease-modifying anti-rheumatic drugs (tDMARD) on patients with rheumatoid arthritis (RA) and type 2 diabetes mellitus (T2DM).Objectives:The objective was to compare T2DM-related healthcare resource utilization (HCRU) and cost for TNF inhibitors (TNFi)-naive patients pooled from two commercial databases with RA and T2DM receiving abatacept, other non-TNFi, or TNFi.Methods:A retrospective, observational study was conducted with MarketScan and PharMetrics (January 2008-September 2018). The study population included TNFi-naïve adult patients with RA and T2DM newly initiating abatacept, TNFi (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) or other non-TNFi (tocilizumab, anakinra, sarilumab, rituximab, tofacitinib). Date of tDMARD initiation was the index date. Patients had ≥2 RA diagnoses separated by ≥7 days, ≥1 T2DM diagnosis, and had ≥12 months of pre-index continuous enrollment. Follow-up ended at the end of patient insurance enrollment, study period or index treatment. T2DM-related HCRU and costs including inpatient stay, outpatient visits, ER visits, and pharmacy use were measured on a per-patient-per-month (PPPM) basis (2018 USD). Patients treated with abatacept were matched to TNFi and non-TNFi cohorts separately by propensity score adjusted with patients baseline comorbidities, HCRU, and costs.Results:A total of 16,236 patients meeting criteria were identified. Most patients were female (74.3%), and the overall average age of 55.4 years (Table 1). After matching, 850 pairs of abatacept vs non-TNFi patients, and 1,096 pairs of abatacept vs TNFi patients were included in the adjusted results. Patients initiating abatacept had $144 lower adjusted T2DM-related costs as compared to non-TNFi and $79 lower costs than TNFi cohorts (Table 2).Table 1.Patient CharacteristicsAbataceptn=1,134Non-TNFin=1,353TNFin=13,749TotalN=16,236Age, mean years (SD)58.5 (11.3)57.7 (11.2)54.9 (10.6)55.41 (10.7)Gender, female, n (%)936 (82.5)993 (73.4)10,142 (73.8)12,071 (74.3)CCI, mean (SD)2.2 (1.4)2.3 (1.4)1.8 (1.1)1.89 (1.14)DCSI, n (%) Cardiovascular361 (31.8)406 (30.0)2,500 (18.2)3,267 (20.1) Neuropathy294 (25.9)374 (27.6)3,161 (23.0)3,829 (23.6) Nephropathy146 (12.9)193 (14.3)1,151 (8.4)1,490 (9.2) PVD131 (11.6)155 (11.5)874 (6.4)1,160 (7.1) Retinopathy103 (9.1)119 (8.8)922 (6.7)1,144 (7.0) Cerebrovascular74 (6.5)102 (7.5)620 (4.5)796 (4.9) Metabolic9 (0.8)20 (1.5)141 (1.0)170 (1.0)CCI: Charlson comorbidity index; DCSI: diabetes complications severity index; PVD: peripheral vascular disease.Table 2.Adjusted T2DM-related HCRU and Costs after Propensity Score MatchingAbataceptn=850Non-TNFin=850Diff (ABA- Non-TNF)Abataceptn=1,096TNFin=1,096Diff (ABA- TNF)T2DM-related HCRU (per 1000 Patients per Month)Number of Hospitalizations13.920.4-6.5*12.614.9-2.3*Number ofER Visits22.016.15.9*18.416.32.0*Number ofOutpatient Visits311334.8-23.7*299.3286.912.4T2DM-related Costs (PPPM $)Inpatient Costs507535-28413475-62ER Costs271710*2225-3Outpatient Costs190323-13318617016*Pharmacy Costs1071007*97128-31Total Costs831975-144719798-79**P<0.05Conclusion:TNFi-naive RA patients with T2DM newly initiating abatacept had lower adjusted rates of T2DM-related hospitalizations compared to patients who initiated a non-TNFi or a TNFi. Total costs were lower among patients initiating abatacept vs. patients who initiated a non-TNFi or a TNFi. Findings suggest that initial abatacept among TNFi-naïve patients may be able to reduce healthcare utilization arising from T2DM complications and reduce T2DM-related costs in RA patients.Disclosure of Interests:Xue Han Employee of: BMS, Qian Xia Shareholder of: I own shares of Bristol-Myers Squibb Company, Employee of: I am a paid employee of Bristol-Myers Squibb Company, Ying Bao Shareholder of: Bristol-Myers Squibb, Employee of: Bristol-Myers Squibb, Vardhaman PATEL Employee of: Bristol Myers Squibb, Amrina Roy Employee of: Mu-Sigma, Varshini Rajagopalan Employee of: Mu-Sigma, Francis Lobo Shareholder of: Bristol-Myers Squibb (US), Employee of: Bristol-Myers Squibb (US)

Abstract
Background:The mechanistic association ofHLA-DRB1alleles that code a “shared epitope” (SE) with rheumatoid arthritis (RA) is not yet clear. Previous data has suggested the carriage of SE is associated with the production of cyclic citrullinated peptide antibodies (anti-CCP)1and severe RA2-4. The interrelationship among SE, anti-citrullinated protein antibody (ACPA) positivity and disease outcomes is not fully understood.Objectives:To assess the RA prognosis associated with the carriage of SE, in relation to ACPA positivity.Methods:Pts enrolled in a large RA registry, Brigham and Women’s Hospital RA Sequential Study between March 2003 to June 2018, with known SE and ACPA status were included in the analysis. HLA-DRB1 SE status was determined by allele-specific polymerase chain reaction and DNA sequencing for most of the subjects and by GWAS-based imputation for the rest. Disease activity (DA) was measured at baseline (BL) and 1-year follow-up by DAS28(CRP), CDAI and SDAI. Pts were stratified by SE+ (1 or 2 SE alleles) and SE- (0 alleles) and ACPA status. We analyzed the relationship of SE with ACPA positivity and change in DA by a linear regression model separately. A mediation analysis was used to examine the mediating effect of ACPA on association between SE and change in DA.Results:Out of 926 pts included in the analysis, 65.1% were SE+, of whom 75.6% were ACPA+. In comparison, 51.7% were ACPA+ in SE- pts. SE+ pts were similar with SE- pts in age, gender, BMI and smoking status, but had longer disease duration, were more likely to be rheumatoid factor positive, have erosive disease and higher comorbidity burden irrespective of ACPA status. The differences were more pronounced if the pts were also ACPA+. Adjusting for BL differences, pts with SE 1 and 2 alleles (vs 0) had an odd ratio of 1.97 (95% CI:1.36-2.84; p=0.0003) and 3.82 (95% CI: 2.44-5.98; p<.0001) to be ACPA +, respectively. The regression analysis suggests that SE+ (vs SE-) pts had an average increase in DAS28 (CRP) of 0.22 (p=0.033), CDAI of 2.07 (p=0.045) and SDAI of 2.43 (p=0.029) over a year (Fig 1). Using a mediation analysis, the direct effect of SE+ account for 78.8% to 81.0% of total effect in the increase in DAS28 (CRP), CDAI and SDAI, and the indirect effect mediated by ACPA account for 19.0% to 21.2% (Table 1).Table 1.Mediation Analysis for SE and ACPA Association with Change in DAParameterChange in DAS28 CRP (N=666)Change in CDAI (N=653)Change in SDAI (N=629)EstimateP-valueEstimateP-valueEstimateP-valueTotal Effect of SE on DA change0.220.0342.050.0472.400.030Direct effect of SE on DA change excluding mediation of ACPA0.170.1011.570.1401.890.098Indirect effect of SE on DA change due to ACPA mediation and interaction0.040.1830.480.1330.510.143The model is adjusted with other covariates: Age, Gender, Charlson comorbidity score; baseline biologic use, Smoking status, baseline DA, Interaction term (ACPA*SE)Figure 1.Linear Regression Model for SE Association with Change in Disease Activity *Estimates, p-values are shown as data labels on the graphs; Change in disease activity (DA) = (follow-up DA- baseline DA); The above model is adjusted for age, gender, CCI, baseline DA, baseline biologic use, SE status and smoking statusConclusion:SE is strongly related to ACPA and a greater burden of disease in RA pts.

Abstract
Estrogen-related receptors (ERRs) play indispensable roles in development, energy metabolism, and cancers and are metabolic switches in Drosophila. However, the mechanism underlying their metabolic role is unknown in insects. This study analysed the expression profiles of Bombyx mori ERR (BmERR), hexokinase (BmHK), pyruvate kinase (BmPK) and phosphofructokinase (BmPFK) during embryonic development. The expression of BmERR tended to be similar to that of the other genes. We observed a regulatory association between BmERR and glycolytic rate-limiting enzymes by BmERR overexpression, RNA interference (RNAi), and ERR inhibitors in B. mori embryo cells. Subsequently, ERR cis-regulation elements (ERREs) were predicted and identified in the BmPFK promoter. Transfection assays, electrophoretic mobility shift assays and chromatin immunoprecipitation showed that BmERR can bind to one of these elements to regulate the expression of BmPFK. ERREs were also predicted in the BmHK and BmPK promoters. In the eggs, the expression of glycolytic rate-limiting enzyme genes was suppressed when the expression of BmERR was interference by double-stranded BmERR, the glucose levels also was increased. Meanwhile, the development of silkworm embryos was delayed by about 1 day. These results indicate that BmERR can bind to the ERREs of glycolytic gene promoters and regulate the expression of glycolytic genes, ultimately affecting embryonic development in silkworms.
