- Abstract
Aims: Data regarding the treatment of hip osteoarthritis (OA) with collagen-based extracellular bio-scaffolds are lacking. We evaluated the treatment of hip OA with ultrasound guided intraarticular injections of Collagen-based Medical Device (CMD)., Material and Methods: Forty-four patients with Kellgren-Lawrence grade (KLG) I or II were selected, and 20/44 randomly selected patients (CMD group), were treated with 2 weekly consecutive ultrasound guided intraarticular injections of CMD (MD-HIP, Guna S.p.a. Milan, Italy). An additional 24/44 patients were treated with oral non-steroidal anti-inflammatory drugs (NSAIDs) daily (NSAIDs group). Clinical assessment, X-rays and ultrasound evaluation were performed at baseline, and after 1 month in both groups, and after 3 months in the CMD group. Outcome measures were general pain VAS (0-10), the whole WOMAC score, and the WOMAC specific subscores., Results: CMD and NSAIDs group were homogenous for age, gender, VAS pain and WOMAC scores. The CMD group had significant improvement of the VAS pain (p<0.0001), global WOMAC score (p<0.0001) and WOMAC function (p<0.0001) from baseline to the 1st month, with further improvement from the 1st to the 3rd month (p<0,001; p<0.01; p<0.03, respectively). Significant improvement in WOMAC pain (p<0.0001) and WOMAC stiffness (p<0.0001) was detected at 1st month, with no significant change at 3rd month. In the NSAIDs group significant improvement in WOMAC function was detected after 1 month (p=0.021) only. No adverse events were recorded in the CMD and NSAIDs group., Conclusion: The ultrasound guided intraarticular hip injections of CMD resulted in significant improvement in VAS pain and WOMAC scores compared to treatment with oral NSAIDs.

- Abstract
Background and Objectives: In SSc, ILD is a major cause of morbidity and mortality. We aimed to investigate the performance of DLCO (diffusing capacity of lung carbon monoxide) and FVC (forced vital capacity) delta change (Δ) and baseline values in predicting the development of SSc-ILD., Methods: Longitudinal data of DLCO, FVC, and ILD on the HRCT of SSc patients from the EUSTAR database were evaluated at baseline (t
0 ) and after 12 (±4) (t1 ) and 24 (±4) (t2 ) months., Results: 474/17805 patients were eligible for the study (403 females); 46 (9.7%) developed ILD at t2 . Positivity for anti-topoisomerase antibodies (117 patients) showed an association with ILD development at t2 ( p = 0.0031). Neither the mean t0 to t1 change (Δ) of DLCO nor the mean t0 to t1 FVCΔ predicted the appearance of ILD at t2 . Investigating the possible role of baseline DLCO and FVC values in predicting ILD appearance after 24 (±4) months, we observed a moderate predictive capability of t0 DLCO < 80%, stronger than that of FVC < 80%., Conclusions: We suggest that an impaired baseline DLCO may be predictive of the appearance of ILD after 2 years of follow-up. This result advances the hypothesis that a reduction in gas exchange may be considered an early sign of lung involvement. However, further rigorous studies are warranted to understand the predictive role of DLCO evaluation in the course of SSc.- Published

- Abstract
Purpose: Capecitabine-Temozolomide (CapTem) is an oral chemotherapy regimen for NETs. Both drugs are radiosensitizers. Integrating CapTem and Y90 transarterial radioembolization (TARE) in patients with grade 2 neuroendocrine tumor (NET) liver metastases achieved an encouraging objective response rate (ORR) and progression-free survival (PFS) in a feasibility study. This study expands that report to a larger cohort with longer follow-up., Methods: Therapy consisted of monthly cycles of capecitabine 600 mg/m
2 twice daily for 14 days and temozolomide 150-200 mg/m2 on day 10-14. Simulation angiography was performed during the initial cycle. The dominant lobe was treated with90 Y-resin microspheres using BSA dosimetry on day 7 of the second cycle of CapTem. Patients with bilobar disease had the other lobe treated on day 7 of the third or fourth cycle. CapTem was continued until progression or intolerance. Clinical and laboratory assessment was done monthly and imaging every 3 months., Results: 35/37 patients completed the prescribed regimen. Primary sites of disease were pancreas (16), lung (10), gut (7) and unknown (4). Mean duration of CapTem was 12 months (range, 4-32 months). ORR in the liver was 72% with a disease control rate of 100%. Median PFS was 36 months (95% CI, 25-45 months). Median overall survival was 41 months (95% CI, 24-87 months) from initiation of CapTemY90 therapy and 130 months (95% CI, 56-172 months) from initial diagnosis., Conclusion: Chemoradiation with CapTem and TARE provided durable control of G2 NET liver metastases for substantially longer than expectations for embolotherapy or chemotherapy alone., (© 2023.

- Abstract
Objective: This study was performed to assess the impact of autologous conditioned serum (ACS) when added to preceding intra-articular glucocorticoid therapy on pain, function, and quality of life outcomes over 24 weeks., Methods: In this single-center, randomized controlled trial involving 40 patients with advanced knee osteoarthritis (Kellgren-Lawrence grades III and IV), ACS or saline placebo was injected after 40 mg triamcinolone acetonide (TA) intra-articular injection. Numerical rating scale (NRS) pain scores and Knee Injury and Osteoarthritis Outcome Score (KOOS) assessments were conducted at baseline and at weeks 3, 6, 12, and 24. The primary endpoint was the change in KOOS Pain at 24 weeks. Patient safety events were also monitored., Results: At week 24, TA + ACS significantly improved KOOS Pain, Symptoms, Activities of Daily Living, Quality of Life, and KOOS Sport scores. TA + ACS also outperformed TA + placebo in NRS pain scores (average and maximum intensity) at week 24 and NRS pain score (at rest) at weeks 12 and 24. The TA injection followed by ACS or placebo was well-tolerated., Conclusion: ACS adds long-term pain relief and functional improvement to the short-term pain relief provided by glucocorticoids.

- Abstract
Purpose: Telegenetics services can expand access to guideline-recommended cancer genetic testing. However, access is often not distributed equitably to all races and ethnicities. We evaluated the impact of an on-site nurse-led cancer genetics service in a diverse Veterans Affairs Medical Center (VAMC) oncology clinic on likelihood of germline testing (GT) completion., Methods: We conducted an observational retrospective cohort study of patients who were referred for cancer genetics services at the Philadelphia VAMC between October 1, 2020, and February 28, 2022. We evaluated the association between genetics service (on-site v telegenetics) and likelihood of GT completion in a subcohort of new consults, excluding patients with prior consults and those referred for known history of germline mutations., Results: A total of 238 Veterans, including 108 (45%) seen on site, were identified for cancer genetics services during the study period, with the majority referred for a personal (65%) or family (26%) history of cancer. In the subcohort of new consults, 121 Veterans (54% self-identified race/ethnicity [SIRE]-Black), including 60 (50%) seen on site, were included in the analysis of germline genetic testing completion. In a univariate analysis, patients who were seen by the on-site genetics service had 3.2-fold higher likelihood of completing GT (relative risk, 3.22; 95% CI, 1.89 to 5.48) compared with the telegenetics service. In multivariable regression analysis, the on-site genetics service was associated with higher likelihood of GT completion, but this association was only statistically significant in SIRE-Black compared with SIRE-White Veterans (adjusted RR, 4.78; 95% CI, 1.53 to 14.96; P < .001; P -interaction of race × genetics service = .016)., Conclusion: An on-site nurse-led cancer genetics service embedded in a VAMC Oncology practice was associated with higher likelihood of germline genetic testing completion than a telegenetics service among self-identified Black Veterans.

- Abstract
Importance: Systemic sclerosis (SSc) sine scleroderma (ssSSc) is a subset of SSc defined by the absence of skin fibrosis. Little is known about the natural history and skin manifestations among patients with ssSSc., Objective: To characterize the clinical phenotype of patients with ssSSc compared with patients with limited cutaneous SSc (lcSSc) and diffuse cutaneous SSc (dcSSc) within the EUSTAR database., Design, Setting, and Participants: This longitudinal observational cohort study based on the international EUSTAR database included all patients fulfilling the classification criteria for SSc assessed by the modified Rodnan Skin score (mRSS) at inclusion and with at least 1 follow-up visit; ssSSc was defined by the absence of skin fibrosis (mRSS = 0 and no sclerodactyly) at all available visits. Data extraction was performed in November 2020, and data analysis was performed from April 2021 to April 2023., Main Outcomes and Measures: Main outcomes were survival and skin manifestations (onset of skin fibrosis, digital ulcers, telangiectasias, puffy fingers)., Results: Among the 4263 patients fulfilling the inclusion criteria, 376 (8.8%) were classified as having ssSSc (mean [SD] age, 55.3 [13.9] years; 345 [91.8%] were female). At last available visit, in comparison with 708 patients with lcSSc and 708 patients with dcSSc with the same disease duration, patients with ssSSc had a lower prevalence of previous or current digital ulcers (28.2% vs 53.1% in lcSSc; P < .001; and 68.3% in dcSSc; P < .001) and puffy fingers (63.8% vs 82.4% in lcSSc; P < .001; and 87.6% in dcSSc; P < .001). By contrast, the prevalence of interstitial lung disease was similar in ssSSc and lcSSc (49.8% and 57.1%; P = .03) but significantly higher in dcSSc (75.0%; P < .001). Skin telangiectasias were associated with diastolic dysfunction in patients with ssSSc (odds ratio, 4.778; 95% CI, 2.060-11.081; P < .001). The only independent factor for the onset of skin fibrosis in ssSSc was the positivity for anti-Scl-70 antibodies (odds ratio, 3.078; 95% CI, 1.227-7.725; P = .02). Survival rate was higher in patients with ssSSc (92.4%) compared with lcSSc (69.4%; P = .06) and dcSSc (55.5%; P < .001) after up to 15 years of follow-up., Conclusions and Relevance: Systemic sclerosis sine scleroderma should not be neglected considering the high prevalence of interstitial lung disease (>40%) and SSc renal crisis (almost 3%). Patients with ssSSc had a higher survival than other subsets. Dermatologists should be aware that cutaneous findings in this subgroup may be associated with internal organ dysfunction. In particular, skin telangiectasias in ssSSc were associated with diastolic heart dysfunction.

- Abstract
Background: This study investigated the ability of patients, naïve to adalimumab treatment and self-injection with an autoinjector (AI), to successfully self-administer AVT02, an adalimumab biosimilar, using a custom, ergonomic AI (Alvotech hf., Reykjavik, Iceland)., Research Design and Methods: This was a single-arm, open-label study, consisting of an 8-week active period and 48-week extension phase. Patients with moderate to severe rheumatoid arthritis (RA) self-administered 40 mg AVT02 subcutaneously via AI in the active period, followed by prefilled syringe in the extension phase. The primary endpoint was the percentage of successful self-injections up to Week 8. Usability and robustness of the AI were evaluated in the active period; safety, efficacy, pharmacokinetic and immunogenicity data were assessed throughout the study., Results: The AI success rate was 100%. No handling events were noted up to Week 8. Both C
trough measurements and immunogenicity profile were in line with expectations from previous studies, with no unexpected safety signals., Conclusions: This study demonstrated that AVT02-AI can be successfully and reliably used for repeated self-injections of AVT02 by moderate to severe RA patients, despite no previous experience of adalimumab self-administration. The extension phase provides long-term efficacy and safety data for AVT02 in RA., Study Identifier: NCT04224194.- Published

- Abstract
Systemic sclerosis (SSc) is a rare connective tissue disorder with highest morbidity and mortality among rheumatologic diseases. Disease progression is highly heterogeneous between patients, implying a strong need for individualization of therapy. Four pharmacogenetic variants, namely TPMT rs1800460, TPMT rs1142345, MTHFR rs1801133 and SLCO1B1 rs4149056 were tested for association with severe disease outcomes in 102 patients with SSc from Serbia treated either with immunosuppressants azathioprine (AZA) and methotrexate (MTX) or with other types of medications. Genotyping was performed using PCR-RFLP and direct Sanger sequencing. R software was used for statistical analysis and development of polygenic risk score (PRS) model. Association was found between MTHFR rs1801133 and higher risk for elevated systolic pressure in all patients except those prescribed with MTX, and higher risk for kidney insufficiency in patients prescribed with other types of drugs. In patients treated with MTX, variant SLCO1B1 rs4149056 was protective against kidney insufficiency. For patients receiving MTX a trend was shown for having a higher PRS rank and elevated systolic pressure. Our results open a door wide for more extensive research on pharmacogenomics markers in patients with SSc. Altogether, pharmacogenomics markers could predict the outcome of patients with SSc and help in prevention of adverse drug reactions.

- Abstract
Objectives: The aim of this work was to determine hand joint inflammation in systemic sclerosis (SSc); patients with rheumatoid arthritis (RA) with hand joint involvement were used as controls. Our investigation also aimed at examining the relationship between these subclinical inflammatory changes in the hands, verified by low-frequency MRI, and clinical (especially cardiopulmonary) manifestations, disease activity, and functional capacity in patients with diffuse cutaneous (dcSSc) and limited cutaneous SSc (lcSSc). Methods: Out of 250 SSc patients, the selection included 82 patients with signs and symptoms of joint involvement, and 35 consecutive RA patients. These patients underwent clinical and laboratory investigations, and hand X-ray and MRI of the dominant hand. Synovitis/tenosynovitis, bone edema, and erosions were investigated, and the bone changes were quantified and scored using the RAMRIS method. HAQ index, modified Rodnan skin score, examination of internal organ involvement, and serological markers for SSc, as well as rheumatoid factor (RF) and cyclic citrullinated peptides antibodies (ACPA), were performed on all experimental group subjects. Results: MRI of the dominant hand showed a significantly higher number of cases with synovitis (78%) than the number of patients with clinically swollen joints (17.1%; p < 0.001); bone edema was found in 62 (75.6%) SSc patients. MRI also showed a higher number of erosions (52; 63.4%) compared to those (22; 27.5%) detected with X-ray (p < 0.001). The average values of the total MRI score of synovitis/edema and erosions in the wrist (p < 0.001) and MCP joints (p < 0.001) were statistically higher in RA than in SSc patients (p < 0.001). The probability of the MRI-detected inflammatory changes was considerably higher in SSc patients who had vascular complications (digital ulceration, OR = 4.68; 95% IP: 1.002−22.25; p < 0.05), in patients with more severe functional impairment (OR = 8.22; 95% IP: 1.74−38.89; p < 0.01), and in patients with active disease (OR = 3.132; 95% IP: 1.027−9.551; p < 0.05). In our investigation, patients with a limited form of the disease and with inflammatory changes on MR more often had higher functional impairment compared to the other group without MRI inflammation. Conclusions: Our data show that in SSc MRI can detect a significant subclinical joint inflammation. RAMRIS confirmed the high degree of joint inflammation in RA, but also revealed a great deal of joint inflammation in SSc. That inflammation is associated with systemic inflammation (disease activity), vascular complications, and more severe forms of the disease, as synovitis cannot be precisely diagnosed by the clinical examination of joints. These results suggest that a careful joint investigation is necessary in SSc, and that in symptomatic patients, MRI may identify joint inflammation. In clinical practice, this evidence might drive to an early targeted therapy, thus preventing joint erosions.

- Abstract
Background: Fluoropyrimidines (fluorouracil [5-FU], capecitabine) and irinotecan are commonly prescribed chemotherapy agents for gastrointestinal (GI) malignancies. Pharmacogenetic (PGx) testing for germline DPYD and UGT1A1 variants associated with reduced enzyme activity holds the potential to identify patients at high risk for severe chemotherapy-induced toxicity. Slow adoption of PGx testing in routine clinical care is due to implementation barriers, including long test turnaround times, lack of integration in the electronic health record (EHR), and ambiguity in test cost coverage. We sought to establish PGx testing in our health system following the Exploration, Preparation, Implementation, Sustainment (EPIS) framework as a guide. Our implementation study aims to address barriers to PGx testing., Methods: The Implementing Pharmacogenetic Testing in Gastrointestinal Cancers (IMPACT-GI) study is a non-randomized, pragmatic, open-label implementation study at three sites within a major academic health system. Eligible patients with a GI malignancy indicated for treatment with 5-FU, capecitabine, or irinotecan will undergo PGx testing prior to chemotherapy initiation. Specimens will be sent to an academic clinical laboratory followed by return of results in the EHR with appropriate clinical decision support for the care team. We hypothesize that the availability of a rapid turnaround PGx test with specific dosing recommendations will increase PGx test utilization to guide pharmacotherapy decisions and improve patient safety outcomes. Primary implementation endpoints are feasibility, fidelity, and penetrance. Exploratory analyses for clinical effectiveness of genotyping will include assessing grade ≥3 treatment-related toxicity using available clinical data, patient-reported outcomes, and quality of life measures., Conclusion: We describe the formative work conducted to prepare our health system for DPYD and UGT1A1 testing. Our prospective implementation study will evaluate the clinical implementation of this testing program and create the infrastructure necessary to ensure sustainability of PGx testing in our health system. The results of this study may help other institutions interested in implementing PGx testing in oncology care., Clinical Trial Registration: https://clinicaltrials.gov/ct2/show/NCT04736472, identifier [NCT04736472]., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Varughese, Bhupathiraju, Hoffecker, Terek, Harr, Hakonarson, Cambareri, Marini, Landgraf, Chen, Kanter, Lau-Min, Massa, Damjanov, Reddy, Oyer, Teitelbaum and Tuteja.)

- Abstract
Objective: To assess thrombin generation, fibrin formation, and structure together with the fibrinolytic status in patients with systemic sclerosis (SSc) in relation to the occurrence of digital ulcers (DUs) during the course of disease., Methods: We studied variables of endothelial dysfunction, thrombin generation, overall hemostatic potential, and fibrin clot turbidity in plasma from 58 patients with SSc (39 with DU history and 19 DU-naïve) and 46 matched healthy controls (HCs). Fibrin structure was visualized using scanning electron microscopy (SEM). Finally, 39 patients with a history of DUs were followed for 1.5 years and the predictive value of all investigated markers for new DU onset was explored., Results: Significantly enhanced endogenous thrombin potential (ETP) and prolonged clot lysis time (CLT) were found in patients with DUs compared to HCs. CLT was prolonged in patients with DUs compared to those without, showing good validity in identifying DUs with an area under the curve of 0.7 (95% CI 0.6-0.8). The levels of ETP and intercellular adhesion molecule 1 were independently associated with CLT. Over the follow-up period, 20 patients developed new DUs. CLT was prolonged ( P < 0.001) in patients with new DU episodes, especially those with recurrent DUs. Regression analysis showed that the Raynaud phenomenon visual analog scale and CLT were predictors of new DUs (OR 1.1, 95% CI 1.0-1.1 and OR 1.2, 95% CI 1.1-1.3, respectively). SEM confirmed denser fibrin clots in patients with new DUs., Conclusion: Our results suggest that impaired fibrinolysis might have an emerging role in underlying digital vasculopathy and its progression in SSc., (Copyright © 2022 by the Journal of Rheumatology.)

- Abstract
TGFβ is a pleiotropic cytokine with immunosuppressive activity. In preclinical models, blockade of TGFβ enhances the activity of radiation and invokes T-cell antitumor immunity. Here, we combined galunisertib, an oral TGFβ inhibitor, with stereotactic body radiotherapy (SBRT) in patients with advanced hepatocellular carcinoma (HCC) and assessed safety, efficacy, and immunologic correlatives. Patients ( n = 15) with advanced HCC who progressed on, were intolerant of, or refused sorafenib were treated with galunisertib (150 mg orally twice a day) on days 1 to 14 of each 28-day cycle. A single dose of SBRT (18-Gy) was delivered between days 15 to 28 of cycle 1. Site of index lesions treated with SBRT included liver (9 patients), lymph node (4 patients), and lung (2 patients). Blood for high-dimensional single cell profiling was collected. The most common treatment-related adverse events were fatigue (53%), abdominal pain (46.6%), nausea (40%), and increased alkaline phosphatase (40%). There were two instances of grade 2 alkaline phosphatase increase and two instances of grade 2 bilirubin increase. One patient developed grade 3 achalasia, possibly related to treatment. Two patients achieved a partial response. Treatment with galunisertib was associated with a decrease in the frequency of activated T regulatory cells in the blood. Distinct peripheral blood leukocyte populations detected at baseline distinguished progressors from nonprogressors. Nonprogressors also had increased CD8
+ PD-1+ TIGIT+ T cells in the blood after treatment. We found galunisertib combined with SBRT to be well tolerated and associated with antitumor activity in patients with HCC. Pre- and posttreatment immune profiling of the blood was able to distinguish patients with progression versus nonprogression., (©2020 American Association for Cancer Research.)- Published

- Abstract
Background and Aim: Striving for harmonisation of specialty training and excellence of care in rheumatology, the European League Against Rheumatism (EULAR) established a task force to develop points to consider (PtCs) for the assessment of competences during rheumatology specialty training., Methods: A systematic literature review on the performance of methods for the assessment of competences in rheumatology specialty training was conducted. This was followed by focus groups in five selected countries to gather information on assessment practices and priorities. Combining the collected evidence with expert opinion, the PtCs were formulated by the multidisciplinary task force, including rheumatologists, medical educationalists, and people with rheumatic and musculoskeletal diseases. The level of agreement (LoA) for each PtC was anonymously voted online., Results: Four overarching principles and 10 PtCs were formulated. The overarching principles highlighted the importance of assessments being closely linked to the rheumatology training programme and protecting sufficient time and resources to ensure effective implementation. In the PtCs, two were related to overall assessment strategy (PtCs 1 and 5); three focused on formative assessment and portfolio (PtCs 2-4); three focused on the assessment of knowledge, skills or professionalism (PtCs 6-8); one focused on trainees at risk of failure (PtC 9); and one focused on training the trainers (PtC 10). The LoA (0-10) ranged from 8.75 to 9.9., Conclusion: These EULAR PtCs provide European guidance on assessment methods throughout rheumatology training programmes. These can be used to benchmark current practices and to develop future strategies, thereby fostering continuous improvement in rheumatology learning and, ultimately, in patient care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

- Abstract
Lessons Learned: Palbociclib monotherapy demonstrated minimal clinical activity in patients with previously treated gastroesophageal cancers. Further clinical evaluation of palbociclib monotherapy is not warranted in gastroesophageal cancers, but improved understanding of resistance mechanisms may permit rational combination approaches., Background: Dysregulation of the cell cycle is a hallmark of cancer. Progression through the G1/S transition requires phosphorylation of retinoblastoma (RB) by cyclin-dependent kinases (CDKs) 4 and 6, which are regulated by cyclins D and E. Amplifications of cyclin D loci and activating mutations in CDKs are frequent molecular aberrations in gastroesophageal malignancies. We conducted a phase II trial of the CDK4/6 inhibitor palbociclib as an initial test of efficacy., Methods: Patients with previously treated metastatic gastroesophageal cancers with intact RB nuclear expression by immunohistochemistry were treated with 125 mg daily of palbociclib for days 1-21 of 28-day cycles. The primary endpoint was overall response rate., Results: We screened 29 patients and enrolled 21 patients: 5 with gastric adenocarcinoma, 3 with gastroesophageal junction adenocarcinoma, 8 with esophageal adenocarcinoma, and 5 with esophageal squamous cell carcinoma. All 29 tumors screened had intact nuclear RB expression, and four treated patients tested positive for CCND1 overexpression. No objective responses were seen. Median progression-free survival was 1.8 months, and median overall survival was 3.0 months. All recurrent grade 3 or 4 toxicities were hematologic, with neutropenia in eight patients (38%), anemia in four patients (19%), and thrombocytopenia in two patients (10%)., Conclusion: Palbociclib has limited single-agent activity in gastroesophageal tumors., (© AlphaMed Press; the data published online to support this summary are the property of the authors.)

- Abstract
Gastrointestinal (GI) malignancies are among the most commonly diagnosed cancers worldwide. Despite the introduction of targeted and immunotherapy agents in the treatment landscape, cytotoxic agents, such as fluoropyrimidines and irinotecan, remain as the cornerstone of chemotherapy for many of these tumors. Pharmacogenetics (PGx) is a rapidly evolving field that accounts for interpatient variability in drug metabolism to predict therapeutic response and toxicity. Given the significant incidence of severe treatment-related adverse events associated with cytotoxic agents, utilizing PGx can allow clinicians to better anticipate drug tolerability while minimizing treatment interruptions or delays. In this review, the PGx profiles of drug-gene pairs with potential impact in GI malignancy therapy - DPYD-5-fluorouracil/capecitabine and UGT1A1-irinotecan - and the available clinical evidence of their roles in reducing severe adverse events are discussed. Considerations for clinical implementation, such as optimal laboratory workflows, electronic health record integration, and stakeholder engagement, as well as provider education, are addressed. Last, exploratory PGx markers in GI malignancy treatment are described. As the PGx knowledge base rapidly evolves, pharmacists will be vital in leveraging their pharmacology knowledge and clinical skills to implement PGx testing in the clinic., (© 2020 Pharmacotherapy Publications, Inc.)

- Abstract
Background: In the randomized, phase III, global SELECT-COMPARE study, upadacitinib 15 mg demonstrated efficacy at week 12 versus placebo and adalimumab with methotrexate (MTX) in patients with rheumatoid arthritis and inadequate response to MTX, which was maintained over 48 weeks. This post hoc analysis of SELECT-COMPARE reports the efficacy and safety of upadacitinib in Central and Eastern European (CEE) patients., Methods: Patients were randomized 2:2:1 to upadacitinib 15 mg once daily, placebo, or adalimumab 40 mg every other week, and continued MTX. Efficacy and safety were assessed through 48 weeks. Primary endpoints were the achievement of ≥20% improvement in American College of Rheumatology response criteria and Disease Activity Score in 28 joints with C-reactive protein <2.6 responses at week 12 for upadacitinib versus placebo. No statistical comparisons were conducted., Results: A total of 596 patients from 12 CEE countries were randomized. At week 12, a numerically greater proportion of patients receiving upadacitinib versus placebo or adalimumab achieved ≥20% improvement in American College of Rheumatology response criteria (72% versus 33% and 59%), Disease Activity Score in 28 joints with C-reactive protein <2.6 (26% versus 4% and 11%), low disease activity and remission, and improved physical function, with results maintained over 48 weeks. Upadacitinib treatment numerically inhibited structural progression versus placebo at week 26. Serious infection and herpes zoster rates were numerically higher with upadacitinib versus adalimumab (2.7 versus 1.7 and 2.3 versus 1.1 events/100 patient-years, respectively) over 48 weeks., Conclusion: Consistent with the global population of patients with rheumatoid arthritis and an inadequate response to MTX, in CEE patients, upadacitinib 15 mg demonstrated clinical and functional improvements versus placebo and adalimumab, radiographic improvements versus placebo, and reasonable safety, over 48 weeks., Competing Interests: Disclosure and potential conflicts of interest: Karel Pavelka has received honoraria from AbbVie, Amgen, BMS, Egis, Hospira, Medac, MSD, Pfizer, Roche, and UCB.

- Abstract
Objective: To evaluate the efficacy and safety of PF-06651600 (ritlecitinib), an irreversible inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, in comparison with placebo in patients with rheumatoid arthritis (RA)., Methods: An 8-week, phase II, double-blind, parallel-group study was conducted. Seventy patients who were seropositive for anti-citrullinated protein antibodies and/or rheumatoid factor were randomized 3:2 to receive oral PF-06651600 (200 mg once daily) or placebo for 8 weeks. Eligible patients had an inadequate response to methotrexate, and the study design allowed up to 50% of patients to have previously received 1 tumor necrosis factor inhibitor that was inadequately effective and/or not tolerated. The primary end point was change from baseline in the Simplified Disease Activity Index (SDAI) score at week 8, assessed by Bayesian analysis using an informative prior distribution for placebo response., Results: Mean change from baseline in the SDAI score at week 8 was greater in the PF-06651600 group (-26.1 [95% credible interval -29.7, -22.4]) than in the placebo group (-16.8 [95% credible interval -20.9, -12.7]; P < 0.001). Most adverse events (AEs) were mild in severity, and no treatment-related serious AEs, severe AEs, or deaths were reported. The most common classes of AE were infections and infestations as well as skin and subcutaneous tissue disorders; there was 1 mild case of herpes simplex in the PF-06651600 group that was considered to be treatment related, which resolved within 3 days without study treatment discontinuation or antiviral therapy., Conclusion: Treatment with the oral JAK3/TEC inhibitor PF-06651600 (200 mg once daily) was associated with significant improvements in RA disease activity and was generally well-tolerated in this small 8-week study., (© 2020 Pfizer Inc.

- Abstract
Background: The aim of this study was to evaluate chemosensory function and oral disorders in patients with primary Sjögren's syndrome (pSS) and to compare these findings with those of age- and gender-matched healthy controls., Methods: This comparative cross-sectional study included 58 patients with primary Sjögren's syndrome (pSS) and 55 age- and gender-matched healthy controls. Olfactory and gustatory function, burning sensations in the tongue (BST) and halitosis were assessed. Oral health-related quality of life (OHRQoL) was evaluated using the short-form Oral Health Impact Profile (OHIP-14)., Results: Patients with pSS had significantly lower self-reported visual analogue scale (VAS) smell score (8.6 ± 2.2 vs. 9.6 ± 0.7, p = 0.016) and VAS taste score (8.5 ± 2.1 vs. 9.5 ± 0.7, p = 0.014) than healthy controls. A greater proportion of patients with pSS had anosmia (3.8% vs. 0.0%) or hyposmia (36.5% vs. 13.2%) and ageusia for basic tastes: sweetness (34.0% vs. 7.5%), sourness (10.6% vs. 0.0), saltiness (10.0% vs. 5.7%) or bitterness (19.1% vs. 1.9%) as evaluated using Sniffin Sticks test and taste stripts, respectively. A higher proportion of pSS patients complained of dysgeusia (52.6% vs. 9.4%, p < 0.0001) and BST (45.6% vs. 0.0%, p < 0.0001), while similar number of patients with pSS and controls reported halitosis (31.6% vs. 28.3%, p = 0.434). The mean OHIP-14 score was significantly higher in patients with pSS (6.8 ± 7.0 vs. 2.3 ± 8.5, p < 0.001) indicating patients' poorer OHRQoL compared with controls., Conclusions: The majority of patients with pSS had impaired chemosensory function and indicators of oral health in comparison with the age- and gender-matched healthy controls. Further studies of oral hygiene habits and dietary intake of these patients are needed to ensure better management of oral health problems in patients with pSS.

- Abstract
Objective: High frequency ultrasound allows visualization of epidermis, dermis and hypodermis, precise measurement of skin thickness, as well as assessment of skin oedema, fibrosis and atrophy. The aim of this pilot cross-sectional observational study was to assess the performance and multiobserver variability of ultra-high-frequency (UHF) (50 MHz) ultrasound (US) in measuring skin thickness as well as the capacity of UHF-derived skin features to differentiate SSc patients from healthy controls., Methods: Twenty-one SSc patients (16 limited and five diffuse SSc) and six healthy controls were enrolled. All subjects underwent US evaluation by three experts at three anatomical sites (forearm, hand and finger). Dermal thickness was measured and two rectangular regions of interest, one in dermis and one in hypodermis, were established for texture feature analysis., Results: UHF-US allowed a precise identification and measurement of the thickness of the dermis. The dermal thickness in the finger was significantly higher in patients than in controls (P < 0.05), while in the forearm it was significantly lower in patients than in controls (P < 0.001). Interobserver variability for dermal thickness was good to excellent [forearm intraclass correlation coefficient (ICC) = 0.754; finger ICC = 0.699; hand ICC = 0.602]. Texture computed analysis of dermis and hypodermis was able to discriminate between SSc and healthy subjects (area under the curve >0.7)., Conclusion: These preliminary data show that skin UHF-US allows a very detailed imaging of skin layers, a reliable measurement of dermal thickness, and a discriminative capacity between dermis and hypodermis texture features in SSc and healthy subjects., (© The Author(s) 2019.

- Abstract
Objectives: Racial factors play a significant role in SSc. We evaluated differences in SSc presentations between white patients (WP), Asian patients (AP) and black patients (BP) and analysed the effects of geographical locations., Methods: SSc characteristics of patients from the EUSTAR cohort were cross-sectionally compared across racial groups using survival and multiple logistic regression analyses., Results: The study included 9162 WP, 341 AP and 181 BP. AP developed the first non-RP feature faster than WP but slower than BP. AP were less frequently anti-centromere (ACA; odds ratio (OR) = 0.4, P < 0.001) and more frequently anti-topoisomerase-I autoantibodies (ATA) positive (OR = 1.2, P = 0.068), while BP were less likely to be ACA and ATA positive than were WP [OR(ACA) = 0.3, P < 0.001; OR(ATA) = 0.5, P = 0.020]. AP had less often (OR = 0.7, P = 0.06) and BP more often (OR = 2.7, P < 0.001) diffuse skin involvement than had WP. AP and BP were more likely to have pulmonary hypertension [OR(AP) = 2.6, P < 0.001; OR(BP) = 2.7, P = 0.03 vs WP] and a reduced forced vital capacity [OR(AP) = 2.5, P < 0.001; OR(BP) = 2.4, P < 0.004] than were WP. AP more often had an impaired diffusing capacity of the lung than had BP and WP [OR(AP vs BP) = 1.9, P = 0.038; OR(AP vs WP) = 2.4, P < 0.001]. After RP onset, AP and BP had a higher hazard to die than had WP [hazard ratio (HR) (AP) = 1.6, P = 0.011; HR(BP) = 2.1, P < 0.001]., Conclusion: Compared with WP, and mostly independent of geographical location, AP have a faster and earlier disease onset with high prevalences of ATA, pulmonary hypertension and forced vital capacity impairment and higher mortality. BP had the fastest disease onset, a high prevalence of diffuse skin involvement and nominally the highest mortality., (© The Author(s) 2019.

- Abstract
Objective: To evaluate fenebrutinib, an oral and highly selective non-covalent inhibitor of Bruton's tyrosine kinase (BTK), in patients with active rheumatoid arthritis (RA)., Methods: Patients with RA and inadequate response to methotrexate (cohort 1, n=480) were randomized to fenebrutinib (50 mg once daily, 150 mg once daily, 200 mg twice daily), 40 mg adalimumab every other week, or placebo. Patients with RA and inadequate response to tumor necrosis factor inhibitors (cohort 2, n=98) received fenebrutinib (200 mg twice daily) or placebo. Both cohorts continued methotrexate therapy., Results: In cohort 1, American College of Rheumatology scores (ACR50) at week 12 were similar for fenebrutinib 50 mg once daily and placebo, and higher for fenebrutinib 150 mg once daily (28%) and 200 mg twice daily (35%) than placebo (15%) (p=0.017; p=0.0003). Fenebrutinib 200 mg twice daily and adalimumab (36%) were comparable (p=0.81). In cohort 2, more patients achieved ACR50 with fenebrutinib 200 mg twice daily (25%) than placebo (12%) (p=0.072). The most common adverse events for fenebrutinib included nausea, headache, anemia, and upper respiratory tract infections. Fenebrutinib had significant effects on myeloid and B cell biomarkers (CCL4 and rheumatoid factor). Fenebrutinib and adalimumab caused overlapping as well as distinct changes in B cell and myeloid biomarkers., Conclusion: Fenebrutinib demonstrated efficacy comparable to adalimumab in patients with an inadequate response to methotrexate, and safety consistent with existing immunomodulatory therapies for RA. These data support targeting both B and myeloid cells via this novel mechanism for potential efficacy in the treatment of RA., (This article is protected by copyright. All rights reserved.)

- Abstract
Capillaroscopy is a non-invasive and safe tool which allows the evaluation of the morphology of the microcirculation. Since its recent incorporation in the 2013 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria for systemic sclerosis together with its assessed role to monitor disease progression, capillaroscopy became a 'mainstream' investigation for rheumatologists. Given its increasing use by a variety of physicians internationally both in daily practice to differentiate primary from secondary Raynaud's phenomenon, as well as in research context to predict disease progression and monitor treatment effects, standardisation in capillaroscopic image acquisition and analysis seems paramount. To step forward to this need, experts in the field of capillaroscopy/microcirculation provide in this very consensus paper their view on image acquisition and analysis, different capillaroscopic techniques, normal and abnormal capillaroscopic characteristics and their meaning, scoring systems and reliability of image acquisition and interpretation., (Copyright © 2020 The Authors.

- Abstract
Objectives: This study aims to assess the possible relationship between
99m Tc-pertechnetate hand perfusion scintigraphy (HPS) and nailfold capillaroscopy (NC) in systemic sclerosis (SSc) patients., Patients and Methods: The study group consisted of 25 SSc patients (6 males; 19 females; mean age 54.2±9.7 years; range, 32 to 67 years), 18 female patients with primary Raynaud's phenomenon (PRP) (mean age 47.1±9.5 years; range, 34 to 65 years) and 10 healthy individuals (3 males, 7 females; mean age 52.7±12.6 years; range, 37 to 73 years). NC and99m Tc-pertechnetate HPS were performed in all examinees. The capillaroscopic findings were classified as normal or scleroderma pattern ("early", "active", or "late"). The fingers-to-palm ratios were calculated for both blood flow (BF) and blood pool (BP) phases of the99m Tc-pertechnetate HPS., Results: Systemic sclerosis patients showed a significantly lower BP ratio than PRP patients and healthy subjects (p=0.004). No statistically significant difference was observed between the SSc and PRP patients in respect to BF ratio. A gradual decrease of BF and BP with the severity of NC microangiopathy pattern ("early", "active" or "late") was found in SSc patients, while the differences were not statistically significant. Patients with diffuse SSc showed lower BF and higher BP than those with limited SSc, while these differences were without statistical significance. There was no significant correlation between BF or BP values and type of SSc (limited or diffuse) (p=0.77 versus p=0.54, respectively) as well as three microangiopathy patterns (p=0.22 versus p=0.54, respectively)., Conclusion:99m Tc-pertechnetate HPS improves the evaluation of vascular damage in SSc patients. There is no direct relationship between NC and99m Tc-pertechnetate HPS; however, the two methods complement each other in the assessment of microcirculation in SSc., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2020, Turkish League Against Rheumatism.)- Published

26. Microparticles in systemic sclerosis, targets or tools to control fibrosis: This is the question!
- Author

Čolić J, Matucci Cerinic M, Guiducci S, and Damjanov N
- Abstract
Systemic sclerosis is the main systemic fibrotic disease with unknown etiology characterized by peripheral microvascular injury, activation of immune system, and wide-spread progressive fibrosis. Microparticles can be derived from any cell type during normal cellular differentiation, senescence, and apoptosis, and also upon cellular activation. Carrying along a broad range of surface cytoplasmic and nuclear molecules of originating cells, microparticles are closely implicated in inflammation, thrombosis, angiogenesis, and immunopathogenesis. Recently, microparticles have been proposed as biomarkers of endothelial injury, which is the primary event in the genesis of tissue fibrosis. Microparticles may have a role in fostering endothelial to mesenchymal transition, thus giving a significant contribution to the development of myofibroblasts, the most important final effectors responsible for tissue fibrosis and fibroproliferative vasculopathy. Thanks to potent profibrotic mediators, such as transforming growth factor beta, platelet-derived growth factor, high mobility group box 1 protein, nicotinamide adenine dinucleotide phosphate oxidase 4, and antifibrotic agents, such as matrix metalloproteinases, microparticles may play an opposite role in fibrosis., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2019.)

- Abstract
Objectives: To assess the association between salivary ultrasonography (sUS) findings and disease activity and damage in patients with primary Sjogren's syndrome (pSS). We investigated the potential prognostic role of sUS as a tool in the assessment of disease activity., Methods: In 303 pSS patients, disease activity was assessed by the European League Against Rheumatism (EULAR) Sjogren's Syndrome Disease Activity Index (ESSDAI), the EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI), the Sjogren's Syndrome Disease Activity Index (SSDAI) and the Sjogren's Syndrome Disease Damage Index (SSDDI). The sUS parenchymal inhomogeneity (de Vita scoring system) was assessed in 303 pSS patients and 111 heathy controls. A receiver operating characteristic (ROC) curve was used to determine the cut-off value of the pathological sUS score. Logistic regression analysis was performed to assess risk factors for moderate and high disease activity., Results: A pathological sUS score ≥ 2 was recorded in 271 (89.7%) patients and 8 (8.6%) healthy controls. Patients with moderate and high ESSDAI and SSDAI scores had significantly higher US activity in comparison to that of pSS patients with low disease activity (p = 0.006; p = 0.01, respectively). Additionally, pSS patients with moderate and high SSDDI scores had higher US activity (p = 0.031). Pathological sUS correlated with the glandular domain within the ESSDAI and SSDDI (p<0.001). The patients with a severe US score (5-6) had a 3.5 times greater chance of having moderate or high disease activity. The specificity of the severe de Vita sUS score for ESSDAI and SSDAI was 85.1% and 85.2%, respectively. In contrast, the sensitivity of a severe de Vita sUS score for ESSDAI was low, at 29.2%, while the sensitivity for the SSDAI was higher, 42.3%. In the analysis of disease activity, a de Vita score ≥ 5 could be used as a risk factor for moderate and high ESSDAI (p = 0.042) and SSDAI (p = 0.006)., Conclusions: Pathological salivary gland ultrasonography is associated with high disease activity and damage in pSS. Consequently, sUS abnormalities might be surrogate items for glandular domains in the assessment of disease activity and damage. Thus, ultrasonography of the salivary gland combined with clinical and serological markers might be part of the next prognostic and therapeutic algorithm in the near future., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: In this work, we aimed to establish a clinical target in the management of knee osteoarthritis (KOA) and to propose good clinical practice (GCP) statements for carrying out a treat-to-target strategy., Methods: A steering committee of seven experts had formulated a provisional set of recommendations that were exposed for discussion and modification to a technical expert panel (TEP) of 25 multidisciplinary experts from Europe, North America, South America and Asia. The level of evidence and strength of each recommendation was discussed. The TEP formulated overarching principles and GCP statements based on the level of agreement for each item with a vote using a 10-point numerical scale., Results: Two overarching principles and 10 GCP statements were formulated by the TEP. These GCP statements suggest: treatment should achieve clinical improvement bringing the patient to the Patient Acceptable Symptom State (PASS); pharmacological and nonpharmacological treatment should begin as early as possible, with an early diagnosis of symptomatic KOA; the patient should be evaluated every 3-6 months; risk factors of KOA progression should be identified and managed with patients at the beginning of the treatment and monitored regularly; treatment should be adapted according to patient phenotype and disease severity; healthy lifestyle must be promoted and monitored. The level of agreement average ranged from 8.7 to 9.6 on scale., Conclusions: The proposed overarching principles and GCP statements have the aim of involving patients, general practitioners and multidisciplinary specialists in sharing a therapeutic treat-to-target strategy for KOA management based on the best evidence and expert opinions., Competing Interests: Conflict of interest statement: Abiogen Pharma Spa supported all the costs of the meeting of the authors, including travel and subsistence.

- Abstract
Objectives: To develop and test the reliability of a new semiquantitative scoring system for the assessment of cartilage changes by ultrasound in a web-based exercise as well as a patient exercise of patients with RA., Methods: A taskforce of the Outcome Measures in Rheumatology Ultrasound Working Group performed a systematic literature review on the US assessment of cartilage in RA, followed by a Delphi survey on cartilage changes and a new semiquantitative US scoring system, and finally a web-based exercise as well as a patient exercise. For the web-based exercise, taskforce members scored a dataset of anonymized static images of MCP joints in RA patients and healthy controls, which also contained duplicate images. Subsequently, 12 taskforce members used the same US to score cartilage in MCP and proximal interphalangeal joints of six patients with RA in in a patient reliability exercise. Percentage agreement and prevalence of lesions were calculated, as intrareader reliability was assessed by weighted kappa and interreader reliability by Light's kappa., Results: The three-grade semiquantitative scoring system demonstrated excellent intrareader reliability (kappa: 0.87 and 0.83) in the web-based exercise and the patient exercise, respectively. Interreader reliability was good in the web-based exercise (kappa: 0.64) and moderate (kappa: 0.48) in the patient exercise., Conclusion: Our study demonstrates that ultrasound is a reliable tool for evaluating cartilage changes in the MCP joints of patients with RA and supports further development of a new reliable semiquantitative ultrasound scoring system for evaluating cartilage involvement in RA., (© The Author(s) 2019.

- Abstract
To assess prevalence and change of depression/anxiety symptoms in spondyloarthritis patients and feasibility of depression/anxiety questionnaires. 43 Patients with axial spondyloarthritis (axSpA) and 27 patients with psoriatic arthritis (PsA) were consecutively recruited. There were 34 patients on biologics and 36 patients on nonbiologics. Patients were not previously treated for depression. The demographic variables, pain, patient global assessment, laboratory, clinical findings, diseases activity scores, Beck Depression Inventory (BDI) and Depression Anxiety and Stress Scale-short version (DASS-21) were collected. The study visits were at the beginning, after 1 month, after 3 and after 6 months. In axSpA and PsA patients on biologics, BDI and DASS-21 were significantly lower compared to nonbiologics group during time. The axSpA patients on biologics had significantly lower BDI and depression severity by BDI at each time point and lower DASS-21 after 1, 3 and 6 months. BDI in PsA patients who received biological therapy was significantly lower after 3 and 6 months. In biologics groups, BDI significantly decreased after 3 months in axSpA patients and after 1 month in PsA patients. In axSpA patients, there was a medium correlation between BDI and axial pain, patient global assessment and disease activity scores. The biological therapy significantly affected the depression/anxiety symptoms in axSpA and PsA during time. BDI moderately correlated with pain and disease activity in axSpA. BDI and DASS-21 are easy to use in daily practice.

- Abstract
Background: Upadacitinib, an oral Janus kinase (JAK)1-selective inhibitor, showed efficacy in combination with stable background conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) in patients with rheumatoid arthritis who had an inadequate response to DMARDs. We aimed to evaluate the safety and efficacy of upadacitinib monotherapy after switching from methotrexate versus continuing methotrexate in patients with inadequate response to methotrexate., Methods: SELECT-MONOTHERAPY was conducted at 138 sites in 24 countries. The study enrolled adults (≥18 years) who fulfilled the 2010 American College of Rheumatology (ACR)-European League Against Rheumatism (EULAR) classification criteria for rheumatoid arthritis. Patients with active rheumatoid arthritis despite stable methotrexate were randomly assigned 2:2:1:1 to switch to once-daily monotherapy of of upadacitinib or to continue methotrexate at their existing dose as blinded study drug; starting from week 14, patients assigned to continue methotrexate were switched to 15 mg or 30 mg once-daily upadacitinib per prespecified random assignment at baseline. The primary endpoints in this report are proportion of patients achieving 20% improvement in the ACR criteria (ACR20) at week 14, and proportion achieving low disease activity defined as 28-joint Disease Activity Score using C-reactive protein (DAS28[CRP]) of 3·2 or lower, both with non-responder imputation at week 14. Outcomes were assessed in patients who received at least one dose of study drug. This study is active but not recruiting and is registered with ClinicalTrials.gov, number NCT02706951., Findings: Patients were screened between Feb 23, 2016, and May 19, 2017 and 648 were randomly assigned to treatment. 598 (92%) completed week 14. At week 14, an ACR20 response was achieved by 89 (41%) of 216 patients (95% CI 35-48) in the continued methotrexate group, 147 (68%) of 217 patients (62-74) receiving upadacitinib 15 mg, and 153 (71%) of 215 patients (65-77) receiving upadacitinib 30 mg (p<0·0001 for both doses vs continued methotrexate). DAS28(CRP) 3·2 or lower was met by 42 (19%) of 216 (95% CI 14-25) in the continued methotrexate group, 97 (45%) of 217 (38-51) receiving upadacitinib 15 mg, and 114 (53%) of 215 (46-60) receiving upadacitinib 30 mg (p<0·0001 for both doses vs continued methotrexate). Adverse events were reported in 102 patients (47%) on continued methotrexate, 103 (47%) on upadacitinib 15 mg, and 105 (49%) on upadacitinib 30 mg. Herpes zoster was reported by one (<1%) patient on continued methotrexate, three (1%) on upadacitinib 15 mg, and six (3%) on upadacitinib 30 mg. Three malignancies (one [<1%] on continued methotrexate, two [1%] on upadacitinib 15 mg), three adjudicated major adverse cardiovascular events (one [<1%] on upadacitinib 15 mg, two [<1%] on upadacitinib 30 mg), one adjudicated pulmonary embolism (<1%; upadacitinib 15 mg), and one death (<1%; upadacitinib 15 mg, haemorrhagic stroke [ruptured aneurysm]) were reported in the study., Interpretation: Upadacitinib monotherapy showed statistically significant improvements in clinical and functional outcomes versus continuing methotrexate in this methotrexate inadequate-responder population. Safety observations were similar to those in previous upadacitinib rheumatoid arthritis studies., Funding: AbbVie Inc, USA., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

- Abstract
Background: Concurrent chemoradiotherapy is an established component of the nonoperative management of locally advanced head and neck squamous cell carcinoma (HNSCC), but the standard dose of 100 mg/m2 cisplatin every 3 weeks is associated with clinically significant toxicity. Interest in a more tolerable regimen has led to the widespread use of weekly lower dose cisplatin, but few randomized trials have compared these approaches., Methods: We examined outcomes of patients with stage III-IVb HNSCC treated with definitive intent chemoradiotherapy using either high-dose cisplatin (HDC) or low-dose cisplatin (LDC), using population-based Veterans Affairs data. In an intent-to-treat analysis, patients were assigned to the HDC vs LDC group according to the dose of their first cycle. Variables potentially influencing treatment decisions including cancer site, stage, smoking/alcohol use, and comorbidities were used to generate propensity scores (PS) for the use of HDC. We compared overall survival (OS) by treatment group using Cox regression, adjusting for PS. We then determined the risk of toxicities using PS-adjusted logistic regression., Results: A total of 2901 patients were included in the analysis; 2200 received HDC (mean initial dose 100 mg/m2). The mean initial dose of LDC was 40 mg/m2. After PS adjustment, HDC was not associated with improved OS over LDC (hazard ratio = 0.94, 95% confidence interval = 0.80 to 1.04). Adjusting for PS, HDC was associated with an increased risk of acute kidney injury, neutropenia, dehydration/electrolyte disturbance, and hearing loss., Conclusion: In this large, population-based study of US military veterans, LDC was associated with similar survival to HDC in the nonoperative definitive management of locally advanced HNSCC of the oral cavity, oropharynx, and hypopharynx/larynx. HDC was associated with statistically significantly more toxicity than LDC. Adoption of LDC may reduce toxicity burden while maintaining OS., (Published by Oxford University Press 2018.)

- Abstract
Hepatocellular carcinoma (HCC) is a challenging to treat malignancy with few available systemic therapies. Angiogenesis has been implicated in the pathogenesis of HCC and prior studies have suggested a role for anti-VEGF therapy. Prior to FDA approval of second-line therapy for advanced HCC, from 2008 until 2017, we initiated bevacizumab monotherapy (5-10 mg/kg every 2-3 weeks) in 12 patients with intolerance of or progression during sorafenib therapy. Bevacizumab therapy was well tolerated with only 1/12 patients experiencing a grade 3-4 treatment-related adverse event (transient ischemic attack) and only 2/12 patients discontinued the therapy due to adverse events. Median overall survival was 20.2 months (IQR, 7.0-43.5), with a median time to radiologic progression of 10.4 months (IQR, 2.8-16.1) and a disease control rate of 54%. Taken together, our experience provides rationale for further prospective investigation of bevacizumab for the treatment of advanced HCC., (© 2019 The Authors.

- Abstract
Objective: To evaluate the level of agreement on ultrasonographic (US) lesions among highly experienced sonographers as well as the intraobserver and interobserver reliability of inflammatory and structural US lesions in patients with osteoarthritis (OA) of the foot., Methods: After a systematic literature review, a Delphi survey was performed to test definitions of US lesions in OA of the foot, including inflammatory lesions (ie, synovial hypertrophy [SH], joint effusion [JE], power Doppler signal [PD]), and structural abnormalities (ie, cartilage damage [CD] and osteophytes). Subsequently, the reliability of US in assessing the aforementioned lesions was tested on static images as well as during a live exercise. Reliability was assessed by kappa analyses and prevalence-adjusted bias-adjusted kappa (PABAK) on a dichotomous and an ordinal scale., Results: Intraobserver and interobserver reliability for SH and JE evaluated by binary scoring was good for both components, while the intraobserver reliability for semiquantitative scoring of SH ranged from moderate in the web-based exercise (PABAK 0.49) to good (PABAK 0.8) in the live exercise. Reliability for CD and PD assessments were respectively good and excellent in all exercises (ranged from PABAK 0.61 to 0.79 for CD and 0.88 to 0.95 for PD). The interobserver reliability for the semiquantitative scoring of osteophytes was fair in the live exercise (PABAK 0.36) and moderate in the static exercise (PABAK 0.60)., Conclusions: Consensual US definitions were found to be reliable for assessing inflammatory lesions in OA of the foot, while the use of US to assess structural damage requires further studies., Competing Interests: Competing interests: None declared.

- Abstract
Background: Methotrexate (MTX), a folate analogue, is the most commonly used disease-modifying drug in the treatment of rheumatoid arthritis (RA). However, high interindividual differences in drug response are present among RA patients., Research Design and Methods: In a group of 234 RA patients treated with MTX, we investigated whether rs1650697 polymorphism in DHFR gene may have an impact on MTX efficacy and/or adverse drug effects (ADEs). Relative DAS28 values (rDAS28) were used for the estimation of MTX therapy and all ADEs were recorded. Patients were genotyped for selected polymorphism by real-time PCR method., Results: According to the European League Against Rheumatism criteria after 6 months of MTX therapy, 196 patients (83.8%) were classified as responders (25 (10.7%) were good and 171 (73.1%) were moderate) and 38 patients (16.2%) as nonresponders. ADEs were observed in 55 patients (23.5%)., Conclusions: Our results showed that the presence of T allele might be protective against MTX hepatotoxicity measured by transaminase levels (p = 0.05). Furthermore, among patients who also received low-dose corticosteroids, we have found a lower rDAS value in patients with CC genotype (p = 0.039).

- Abstract
Background: The addition of cisplatin or cetuximab to radiation therapy (RT) improves outcomes in comparison with RT alone in the nonoperative management of head and neck squamous cell carcinoma (HNSCC), but limited data exist for comparing these approaches. Using Veterans Health Affairs data, this study compared the outcomes of patients treated with RT plus cisplatin or cetuximab., Methods: Patients with stage III to IVb HNSCC who had been treated nonsurgically with RT and cisplatin or cetuximab from 2000 to 2016 within the Veterans Health Affairs system were identified. Patients were analyzed by the drug used in the first treatment cycle (intent to treat). Overall survival (OS) was compared by treatment group with Cox regression models, and propensity score (PS) methods were used to account for a treatment allocation bias. The risk of toxicities was determined, with logistic regression models fit into propensity-matched cohorts., Results: A total of 4520 patients were included in the analysis with a median follow-up of 3 years: 83% received cisplatin. Cisplatin patients were younger (P < .001) and had fewer comorbidities (P < .001). In an unmatched analysis, cetuximab was associated with inferior OS (P < .001). After PS matching, cetuximab treatment remained statistically significantly associated with inferior OS (1.7 vs 4.1 years; hazard ratio, 1.61; 95% confidence interval, 1.44-1.79; P < .001). These differences remained significant across all primary HNSCC subsites and in comparison with low- and high-dose cisplatin., Conclusions: Cetuximab with RT yields inferior OS in comparison with cisplatin for the nonoperative management of stage III to IVb HNSCC. According to this study, cisplatin may be the most appropriate partner for RT in this setting., (© 2018 American Cancer Society.)

- Abstract
Objective: Patients with primary Sjögren's Syndrome (pSS) have diminished health quality and fatigue, arthralgia along with dryness of the mouth and eyes have major impact on their psychological and social aspects of life. The purpose of this study was to determine psychological features of patients with pSS. We analyzed personality, depression and anxiety of patients with primary Sjögren's Syndrome (pSS) in comparison with patients with rheumatoid arthritis (RA) and healthy controls (HC) and assessed their association with sociodemographic factors and comorbidity., Methods: In 105 pSS patients (mean age 51.34 years, mean disease duration 5.98 years), 52 RA patients (mean age 51.37 years, mean disease duration 8.10 years) and 54 HC (mean age 51.35 years) clinical and sociodemographic characteristics were determined and results analyzed. At enrollment patients and controls completed the Revisited NEO Personality Inventory Five-Factor model (NEO-PI-R), the Zung Self-Rating Depression Scale and the Zung Self-Rating Anxiety Scale. Statistical analyses were performed using SPSS [Version 16.0]. The relative size of the effect was assessed based on standardized estimates of effect size (d)., Results: Patients with pSS, similarly to RA patients had higher scores of Neuroticism (d = 0.46, p = 0.007) and lower scores of Extraversion (d = 0.51, p = 0.001) and Openness for experience (d = 0.65, p = 0.013) compared to HC. There was no significant differences between pSS group and HC in the depression (d = 0.171, p>0.05). However, patients with pSS had higher anxiety in comparison to HC (p<0.0001). In multivariate models, education and satisfaction with family relationships were significant predictors for psychological characteristics of patients, independently of clinical diagnosis., Conclusions: Our study is the first to show that patients with pSS scored high on neuroticism and anxiety and low on sociability. Education and satisfaction with family relationships predisposed to their psychological profile. Psychological assessment of patients with pSS may improve understanding and treatment of this clinical condition., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: Next-generation sequencing has identified actionable genetic aberrations in intrahepatic cholangiocarcinomas (iCCA), including the fibroblast growth factor receptor 2 (FGFR2) fusions. Derazantinib (ARQ 087), an orally bioavailable, multi-kinase inhibitor with potent pan-FGFR activity, has shown preliminary therapeutic activity against FGFR2 fusion-positive iCCA., Methods: This multicentre, phase 1/2, open-label study enrolled adult patients with unresectable iCCA with FGFR2 fusion, who progressed, were intolerant or not eligible to first-line chemotherapy (NCT01752920). Subjects received derazantinib in continuous daily doses. Tumour response was assessed according to RECIST 1.1 every 8 weeks., Results: Twenty-nine patients (18 women/11 men; median age, 58.7 years), 2 treatment-naive and 27 who progressed after at least one prior systemic therapy, were enrolled. Overall response rate was 20.7%, disease control rate was 82.8%. Estimated median progression-free survival was 5.7 months (95% CI: 4.04-9.2 months). Treatment-related adverse events (AE) were observed in 27 patients (93.1%, all grades), including asthenia/fatigue (69.0%), eye toxicity (41.4%), and hyperphosphatemia (75.9%). Grade ≥ 3 AEs occurred in 8 patients (27.6%)., Conclusion: Derazantinib demonstrated encouraging anti-tumour activity and a manageable safety profile in patients with advanced, unresectable iCCA with FGFR2 fusion who progressed after chemotherapy. A pivotal trial of derazantinib in iCCA is ongoing (NCT03230318).

Objective: The aim of this study was to analyse differences in clinical presentation in patients with early (< 3 years' duration) systemic sclerosis (SSc), comparing three age groups according to disease subsets., Method: Cross-sectional analysis of the prospective EULAR Scleroderma Trials and Research database (EUSTAR) was performed. Patients fulfilling preliminary American College of Rheumatology 1980 classification criteria for SSc, with < 3 years from the first non-Raynaud's SSc symptom at first entry, were selected. Patients with < 3 years from the first SSc symptom, including Raynaud's phenomenon, were also analysed. SSc-related variables, including antibodies, SSc subsets, and organ involvement, were examined. Age was categorized into ≤ 30, 31-59, and ≥ 60 years. We performed descriptive and bivariate analyses., Results: The study included 1027 patients: 90% Caucasian, 80% women, and 40% with diffuse disease. In early stages of SSc, younger patients had significantly more anti-Scl-70 antibodies and diffuse disease. With increasing age, we observed more elevation of estimated pulmonary systolic pressure on echocardiography (5%, 13%, and 30%, respectively, in the three age groups), cardiac conduction blocks (6%, 6%, and 15%), and left ventricular diastolic dysfunction (4%, 12%, and 27%). The results were similar for 650 patients with < 3 years from first SSc symptom, including Raynaud's., Conclusion: In early stages of SSc, older patients showed data indicating more severe disease with greater cardiac involvement. The diffuse subset was more frequent in the younger subgroup. The identification of such differences may help in selecting appropriate management for individual patients in clinical practice.

- Abstract
Systemic sclerosis (SSc) is a heterogeneous multisystem autoimmune disease with unknown etiology. Numerous studies have indicated that the disease heterogeneity implies various genetic abnormalities. Considering that SSc is characterized by a strong sex bias and that the position of IRAK1 gene is on the X chromosome, we assume that variations in IRAK1 gene could explain female predominance of SSc. It was previously described that miR-146a has a role in 'fine-tuning' regulation of the TLR/NF-kB signaling pathway through down-regulation of IRAK1 gene. The aim of the present study was to analyze both variants and expression level of IRAK1 and miR-146a genes in terms of susceptibility to SSc and clinical presentation of SSc patients. We analyzed variants IRAK1 rs3027898 C > A and miR-146a rs2910164 C > G in 102 SSc patients and 66 healthy subjects. Genotyping was performed by Sanger sequencing. Expression level of IRAK1 mRNA and miR-146a in PBMCs was performed in subset of 50 patients and 13 healthy controls by RT-qPCR. Our results showed that there was no association between IRAK1 rs3027898 and the risk of SSc in women. However, the analysis of genotype distribution of the mir-146a rs2910164 C > G variant indicated that CC genotype shows strong association with lung fibrosis and active form of the disease. When expression level of IRAK1 gene was analyzed, we detected significant downregulation of IRAK1 mRNA in SSc patients compared to controls, as well as in male compared to female patients, in patients with ACAs autoantibodies and in patients with severe skin involvement. Regarding the expression level of miR-146a, we have found significantly reduced expression in SSc patients, in patients with skin involvement and in male SSc patients. The results from this study indicate that expression of IRAK1 gene could explain phenotypic heterogeneity of SSc and may be involved in the pathogenesis of SSc due to its differential expression in certain subgroups. Our results also suggested that miR-146a rs2910164 CC genotype may be predisposing factor for development lung fibrosis and more progressive form of SSc. Results from relative expression analysis of miR-146a demonstrated that changes in the level of this miRNA may have an impact on development and clinical course of SSc., (Copyright © 2018 European Federation of Immunological Societies.

- Abstract
Objectives: Stereotactic body radiotherapy (SBRT) is potentially curative treatment for small hepatocellular carcinomas (HCC), but data are limited on its efficacy and toxicity. We hypothesized that SBRT can achieve excellent local control (LC) with acceptable toxicity treating HCC lesions, even in advanced cirrhosis., Materials and Methods: Thirty-seven nonmetastatic HCC patients received SBRT to 43 lesions between October 2012 and April 2016. Median dose was 50 Gy/5 fractions. All Child-Pugh (CP) ≥B patients underwent a planned 1-month break after the first 3 fractions to assess hepatic toxicity. Patients were treated without separately placed fiducial markers using Linac-based SBRT with breath-hold (67%) or 4D-computed tomography with compression belt (33%) to reduce motion. Patients underwent magnetic resonance imaging q3 months post-SBRT., Results: Median age was 65 (range, 44 to 88). Pre-SBRT mean CP was 6.4 (range, A5 to C11). Nine (24%) had CP≥B8. Thirty-one of 33 patients (93%) had prior liver-directed therapy (median 2). Seventeen (40%) had solitary lesions. Median lesion diameter was 2.7 cm (range, 1.1 to 5.6). Median follow-up was 14 months (range, 2 to 45). There was 1 local failure (multifocal HCC with 3 prior transarterial chemoembolization). LC, freedom from liver progression, and overall survival at 12 months was 95%, 66%, 87% in the full cohort, and 100%, 76%, 93% for patients with solitary lesions. Four had grade 3 toxicity (ascites [n=2]/gastrointestinal bleed [n=1]/capsular pain [n=1]). Eight of 9 CP≥B8 patients had no grade ≥3 hepatic toxicity., Conclusions: SBRT for HCC is well-tolerated even in patients with advanced cirrhosis and prior liver-directed treatment and provides excellent LC even for larger lesions that cannot be controlled with radiofrequency ablation. LC with SBRT compares favorably to other liver-directed therapies. Prospective studies comparing SBRT with other liver-directed therapies are warranted.

- Abstract
Background: Physical activity is associated with a lower risk of disease recurrence among colon cancer patients. Circulating tumor cells (CTC) are prognostic of disease recurrence among stage I-III colon cancer patients. The pathways through which physical activity may alter disease outcomes are unknown, but may be mediated by changes in CTCs., Methods: Participants included 23 stage I-III colon cancer patients randomized into one of three groups: usual-care control, 150 min∙wk-1 of aerobic exercise (low-dose), and 300 min∙wk-1 of aerobic exercise (high-dose) for six months. CTCs from venous blood were quantified in a blinded fashion using an established microfluidic antibody-mediated capture device. Poisson regression models estimated the logarithmic counts of CTCs., Results: At baseline, 78% (18/23) of patients had ≥1 CTC. At baseline, older age (-0.12±0.06; P = 0.04), lymphovascular invasion (0.63±0.25; P = 0.012), moderate/poor histology (1.09±0.34; P = 0.001), body mass index (0.07±0.02; P = 0.001), visceral adipose tissue (0.08±0.04; P = 0.036), insulin (0.06±0.02; P = 0.011), sICAM-1 (0.04±0.02; P = 0.037), and sVCAM-1 (0.06±0.03; P = 0.045) were associated with CTCs. Over six months, significant decreases in CTCs were observed in the low-dose (-1.34±0.34; P<0.001) and high-dose (-1.18±0.40; P = 0.004) exercise groups, whereas no significant change was observed in the control group (-0.59±0.56; P = 0.292). Over six months, reductions in body mass index (-0.07±0.02; P = 0.007), insulin (-0.08±0.03; P = 0.014), and sICAM-1 (-0.07±0.03; P = 0.005) were associated with reductions in CTCs. The main limitations of this proof-of-concept study are the small sample size, heterogenous population, and per-protocol statistical analysis., Conclusion: Exercise may reduce CTCs among stage I-III colon cancer patients. Changes in host factors correlated with changes in CTCs. Exercise may have a direct effect on CTCs and indirect effects through alterations in host factors. This hypothesis-generating observation derived from a small pilot study warrants further investigation and replication., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Genetic predisposition to systemic sclerosis (SSc) has still not been fully revealed. Interleukin-6 (IL-6) is a mediator of T cell proliferation and fibrotic events in SSc. Polymorphisms in the IL-6 are found to be important in susceptibility to development of SSc. We aimed to assess the frequency of -174 C/G of IL-6 gene polymorphism in SSc patients and healthy controls, as well as correlation with disease manifestations. In the case-control study, 102 patients with SSc and 93 controls were included. PCR-RFLP method was performed for genotyping promotor variants -174 C/G of IL-6 gene. The expression level of IL-6 was determined by qRT-PCR on subset of 50 patients and 13 healthy controls with different IL-6 genotypes. We used UCLA GIT 2.0 questionnaire to assess gastrointestinal involvement in SSc patients. The expression level of IL-6 gene was significantly higher in patients with SSc in comparison with healthy controls (p < 0.05). Carriers of C-allele of IL-6 gene compared to those with G allele, showed higher expression of IL-6 gene (95.8 vs. 41.2, p < 0.05), higher GIT total score (0.85 vs. 0.5, p < 0.05) and higher distension scale score (1.4 ± 0.9 vs. 0.78 ± 0.8, p = 0.05). No significant differences in genotype distribution and allele frequency were observed between patients and controls. The expression of IL6 gene varies significantly during the course of SSc. The IL-6 gene variant -174 C/G (presence of C-allele) is associated with higher IL-6 gene expression and greater GIT impairment in patients with SSc.

- Abstract
Objectives: An integrated protocol combining capecitibine-temozolomide with yttrium-90 radioembolization (CapTemY90) for liver-dominant grade 2 neuroendocrine tumors (NETs) was designed in the hope of achieving synergistic improvement in liver disease control with no more than additive toxicities. This report describes the feasibility and safety of this regimen., Methods: Twenty-one patients with unresectable grade 2 NET liver-dominant metastases without contraindications to radioembolization or to CapTem initiated therapy with capecitabine 600 mg/m twice daily for 14 days and temozolomide 150 to 200 mg/m in 2 divided doses on days 10 to 14, with 14 days between cycles. During the first cycle, simulation angiography was performed. The dominant lobe was radioembolized on day 7 of the second cycle. In patients with bilobar disease, the other lobe was treated on day 7 of the third or fourth cycle., Results: Nineteen of 21 patients completed the protocol. Adverse events were as expected. Objective response rate was 74% in the liver and 55% for extrahepatic tumor. Median progression-free survival was not reached. Progression-free survival at 3 years was 67%, with 74% progression-free in the liver., Conclusions: CapTemY90 is feasible and safe for grade 2 NETs. Toxicities were additive. Oncologic outcomes suggest synergy.

- Abstract
Aims: Autologous conditioned serum (ACS; marketed as Orthokine®) is an autologous blood product that has previously shown efficacy in treatment of joint osteoarthritis, spinal radiculopathy, tendon and muscle injuries in randomized controlled trials. In this 24-week, randomized, double-blind study, we compared the efficacy and safety of ACS with glucocorticoid (betamethasone) injections in chronic supraspinatus tendinopathy patients., Material and Methods: Thirty-two patients with chronic supraspinatus tendinopathy were enrolled in the study. The ACS group received four ACS injections once weekly over four weeks and the glucocorticoid group received three betamethasone injections once weekly over three weeks with a placebo (saline) injection at week 4 into the enthesis and paratenon of the supraspinatus tendon. Study endpoints were pain intensity (VAS) and Constant Shoulder Score (CSS) assessed at weeks 0, 4 and 24., Results: Shoulder pain intensity improved after 4 weeks and significantly improved after 24 weeks in patients treated with ACS compared with those treated with glucocorticoids (pain intensity week 4: ACS=22.0, glucocorticoid=32.0; week 24: ACS=15.0, glucocorticoid=40.0). CSS improved to a similar extent in both groups after 4 weeks. After 24 weeks, ACS patients exhibited significantly greater CSS improvements than glucocorticoid patients. Adverse events (n=8) were reported in betamethasone patients., Conclusions: Compared with betamethasone, ACS therapy improved joint function and reduced shoulder pain more effectively after 4 weeks of treatment; these improvements were sustained to week 24. Combined with its favorable safety profile, ACS appears to be a more effective treatment than glucocorticoids and could enhance the quality of life in patients with chronic rotator cuff tendinopathy.

Objectives: To describe differences in clinical presentation between men and women in a large group of patients with early (<3 years' duration) systemic sclerosis (SSc) according to disease subsets., Methods: A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research database (EUSTAR) was performed. Patients fulfilling preliminary ACR 1980 classification criteria for SSc, with less than 3 years from the first non-Raynaud's symptom at first entry, were selected. A group of patients with less than 3 years from the first SSc symptom, including Raynaud's phenomenon, was also analysed. SSc related variables, including antibodies, SSc subsets, disease activity and organ involvement were included. Descriptive and bivariate analyses were performed., Results: A total of 1,027 patients were included, 90% Caucasian, 80% women, and 40% with diffuse cutaneous disease. In early stages of SSc, men showed more frequently than women active disease, diffuse cutaneous subset, anti-Scl-70 antibodies, elevated acute phase reactants, muscular and pulmonary involvement. Differences between men and women were confirmed in the limited, but not in the diffuse SSc subset. The results were similar when 650 patients with less than three years from the first SSc symptom, including Raynaud's phenomenon, were analysed., Conclusions: In early stages of SSc, men present signs and symptoms of more severe disease. In the limited disease subset, men might appear with clinical features and organ involvement similar to those of the diffuse subgroup. In clinical practice, the identification of such differences might help to select the appropriate management for each particular patient.

- Abstract
Background: Tivantinib (ARQ 197), a selective, oral MET inhibitor, improved overall survival and progression-free survival compared with placebo in a randomised phase 2 study in patients with high MET expression (MET-high) hepatocellular carcinoma previously treated with sorafenib. The aim of this phase 3 study was to confirm the results of the phase 2 trial., Methods: We did a phase 3, randomised, double-blind, placebo-controlled study in 90 centres in Australia, the Americas, Europe, and New Zealand. Eligible patients were 18 years or older and had unresectable, histologically confirmed, hepatocellular carcinoma, an Eastern Cooperative Oncology Group performance status of 0-1, high MET expression (MET-high; staining intensity score ≥2 in ≥50% of tumour cells), Child-Pugh A cirrhosis, and radiographically-confirmed disease progression after receiving sorafenib-containing systemic therapy. We randomly assigned patients (2:1) in block sizes of three using a computer-generated randomisation sequence to receive oral tivantinib (120 mg twice daily) or placebo (twice daily); patients were stratified by vascular invasion, extrahepatic spread, and α-fetoprotein concentrations (≤200 ng/mL or >200 ng/mL). The primary endpoint was overall survival in the intention-to-treat population. Efficacy analyses were by intention to treat and safety analyses were done in all patients who received any amount of study drug. This study is registered with ClinicalTrials.gov, number NCT01755767., Findings: Between Dec 27, 2012, and Dec 10, 2015, 340 patients were randomly assigned to receive tivantinib (n=226) or placebo (n=114). At a median follow-up of 18·1 months (IQR 14·1-23·1), median overall survival was 8·4 months (95% CI 6·8-10·0) in the tivantinib group and 9·1 months (7·3-10·4) in the placebo group (hazard ratio 0·97; 95% CI 0·75-1·25; p=0·81). Grade 3 or worse treatment-emergent adverse events occurred in 125 (56%) of 225 patients in the tivantinib group and in 63 (55%) of 114 patients in the placebo group, with the most common being ascites (16 [7%] patients]), anaemia (11 [5%] patients), abdominal pain (nine [4%] patients), and neutropenia (nine [4%] patients) in the tivantinib group. 50 (22%) of 226 patients in the tivantinib group and 18 (16%) of 114 patients in the placebo group died within 30 days of the last dose of study medication, and general deterioration (eight [4%] patients) and hepatic failure (four [2%] patients) were the most common causes of death in the tivantinib group. Three (1%) of 225 patients in the tivantinib group died from a treatment-related adverse event (one sepsis, one anaemia and acute renal failure, and one acute coronary syndrome)., Interpretation: Tivantinib did not improve overall survival compared with placebo in patients with MET-high advanced hepatocellular carcinoma previously treated with sorafenib. Although this METIV-HCC trial was negative, the study shows the feasibility of doing integral tissue biomarker studies in patients with advanced hepatocellular carcinoma. Additional randomised studies are needed to establish whether MET inhibition could be a potential therapy for some subsets of patients with advanced hepatocellular carcinoma., Funding: ArQule Inc and Daiichi Sankyo (Daiichi Sankyo Group)., (Copyright © 2018 Elsevier Ltd.

- Abstract
Objective: To examine the dose-response effects of aerobic exercise on health-related quality of life (HRQoL) among colon cancer survivors., Methods: Thirty-nine stage I to III colon cancer survivors were randomized to 1 of 3 groups: usual-care control, 150 min·wk
-1 of aerobic exercise (low-dose) and 300 min·wk-1 of aerobic exercise (high-dose) for 6 months. HRQoL outcomes included the Short Form (SF)-36 physical and mental component summary, Functional Assessment of Cancer Therapy-Colorectal, Pittsburgh Sleep Quality Index, Fear of Cancer Recurrence Inventory, Fatigue Symptom Inventory, and North Central Cancer Treatment Group bowel function questionnaire, assessed at baseline and post intervention. The primary hypothesis was that exercise would improve HRQoL outcomes in a dose-response fashion, such that high-dose aerobic exercise would yield the largest improvements in HRQoL outcomes., Results: Over 6 months, the low-dose group completed 141 ± 10 min·wk-1 of aerobic exercise, and the high-dose group completed 247 ± 11 min·wk-1 of aerobic exercise. Over 6 months, exercise improved the physical component summary score of the SF-36 (Ptrend = 0.002), the Functional Assessment of Cancer Therapy-Colorectal (Ptrend = 0.025), the Pittsburgh Sleep Quality Index (Ptrend = 0.049), and the Fatigue Symptom Inventory (Ptrend = 0.045) in a dose-response fashion. Between-group standardized mean difference effects sizes for the above-described findings were small to moderate in magnitude (0.35-0.75). No dose-response effects were observed for the mental component summary score of the SF-36, the Fear of Cancer Recurrence Inventory, or bowel function., Conclusion: Higher doses of aerobic exercise, up to 300 min·wk-1 , improve multiple HRQoL outcomes among stage I to III colon cancer survivors. These findings provide evidence that aerobic exercise may provide multiple health benefits for colon cancer survivors., (Copyright © 2018 John Wiley & Sons, Ltd.)- Published

- Abstract
The objective of this study was to determine the construct validity and sensitivity to change of Belgrade Ultrasound Enthesitis Score (BUSES) in spondyloarthritis patients. Seventy-six spondyloarthritis patients with enthesitis were included in this pilot, prospective, double-blinded ultrasound study. Thirty-four patients received biological and forty-two patients received non-biological therapy. BUSES was determined at the beginning, after 1, 3, and 6 months. Spearman's correlation coefficient was calculated between BUSES and baseline characteristics. Brunner-Langer mixed non-parametric ANOVA was used to examine sensitivity to change of BUSES and effect of biological therapy on BUSES. Effect of time on the presence of each of the ultrasound enthesitis signs (increased thickness, hypoehogenicity, Power Doppler, enthesophytes, and erosions) was assessed using Cochran Q test. There was a weak, positive correlation between BUSES and disease duration, clinical enthesitis score, BASFI, BASDAI, and ASDAS-ESR/CRP. BUSES was higher at the beginning than after 1 month (p = 0.004), after 3 months (p < 0.001) and after 6 months (p < 0.001), as well as BUSES was higher after 1 month than after 3 months (p < 0.001) and after 6 months (p = 0.002). There is no difference in efficiency between non-biological and biological therapies on BUSES. Increased thickness, hypoechogenicity, and Power Doppler have decreased on Achilles tendon's and plantar fascia's enthesis over time. BUSES has a certain degree of construct validity because of the weak, positive correlation with parameters referring to severity of spondyloarthritis. BUSES demonstrated sensitivity to change over time due to decreasing of ultrasound acute enthesitis signs in treated spondyloarthritis patients. BUSES could be useful for monitoring the progression of enthesitis and effectiveness of the treatment.

Background: Observational studies suggest that higher volumes of physical activity are associated with a lower risk of disease recurrence among survivors of colon cancer. However, the feasibility and safety of prescribing higher volumes of physical activity to survivors of colon cancer are unknown. Furthermore, the pathways through which exercise may reduce disease recurrence are unknown., Patients and Methods: Survivors of stage I to III colon cancer were randomized to usual-care control, 150 minutes per week of aerobic exercise (low-dose), or 300 minutes per week of aerobic exercise (high-dose). Changes in soluble intercellular adhesion molecule-1 and vascular adhesion molecule-1 prognostic biomarkers were examined., Results: From January 2015 to February 2016, 39 patients were enrolled (n = 13 usual-care control; n = 14 low-dose; n = 12 high-dose), and 38 participants completed the study (97% follow-up). Over 6 months, the low-dose group completed 142 minutes per week (92.8% adherence), and the high-dose group completed 247 minutes per week (89.0% adherence) of exercise. Compared with the control group, changes in soluble intercellular adhesion molecule-1 were -134.9 ng/mL (95% confidence interval, -238.1 to -31.6 ng/mL) in the low-dose group and -114.8 ng/mL (95% confidence interval, -222.5 to -7.1 ng/mL) in the high-dose group (linear P
trend = .023; nonlinear Ptrend = .044). No changes were observed for soluable vascular adhesion molecule-1 (linear Ptrend = .791; nonlinear Ptrend = .604). Non-serious adverse events occurred at similar rates among randomized groups. No serious adverse events occurred., Conclusion: Higher volumes of moderate-intensity aerobic exercise, up to 300 minutes per week, are feasible, safe, and elicit favorable changes in prognostic biomarkers among patients recently treated for stage I to III colon cancer. These data can be used to guide clinical recommendations for patients, and inform future trials., (Copyright © 2017 Elsevier Inc. All rights reserved.)- Published
