[PMID: 36709040 PMCID: PMC10619213 DOI: 10.1016/j.annonc.2023.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 12/14/2022] [Accepted: 01/15/2023] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND Very young premenopausal women diagnosed with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+HER2-) early breast cancer (EBC) have higher rates of recurrence and death for reasons that remain largely unexplained. PATIENTS AND METHODS Genomic sequencing was applied to HR+HER2- tumours from patients enrolled in the Suppression of Ovarian Function Trial (SOFT) to determine genomic drivers that are enriched in young premenopausal women. Genomic alterations were characterised using next-generation sequencing from a subset of 1276 patients (deep targeted sequencing, n = 1258; whole-exome sequencing in a young-age, case-control subsample, n = 82). We defined copy number (CN) subgroups and assessed for features suggestive of homologous recombination deficiency (HRD). Genomic alteration frequencies were compared between young premenopausal women (<40 years) and older premenopausal women (≥40 years), and assessed for associations with distant recurrence-free interval (DRFI) and overall survival (OS). RESULTS Younger women (<40 years, n = 359) compared with older women (≥40 years, n = 917) had significantly higher frequencies of mutations in GATA3 (19% versus 16%) and CN amplifications (CNAs) (47% versus 26%), but significantly lower frequencies of mutations in PIK3CA (32% versus 47%), CDH1 (3% versus 9%), and MAP3K1 (7% versus 12%). Additionally, they had significantly higher frequencies of features suggestive of HRD (27% versus 21%) and a higher proportion of PIK3CA mutations with concurrent CNAs (23% versus 11%). Genomic features suggestive of HRD, PIK3CA mutations with CNAs, and CNAs were associated with significantly worse DRFI and OS compared with those without these features. These poor prognostic features were enriched in younger patients: present in 72% of patients aged <35 years, 54% aged 35-39 years, and 40% aged ≥40 years. Poor prognostic features [n = 584 (46%)] versus none [n = 692 (54%)] had an 8-year DRFI of 84% versus 94% and OS of 88% versus 96%. Younger women (<40 years) had the poorest outcomes: 8-year DRFI 74% versus 85% and OS 80% versus 93%, respectively. CONCLUSION These results provide insights into genomic alterations that are enriched in young women with HR+HER2- EBC, provide rationale for genomic subgrouping, and highlight priority molecular targets for future clinical trials.

Abstract
Antimicrobial air filtration techniques have recently been widely studied to enhance indoor air quality and mitigate hazardous airborne microorganisms. Here, CuNPs were incorporated into a commercial polyester fiber surface and Scanning Mobility Particle Sizer was used to measure the adherence between fibers and nanoparticles. An acid pretreatment previous CuNP incorporation was effective against the particle release and enhanced the adhesion between particle and fiber. CuNP was a mixture of Cu0 and Cu2O with a diameter size of 90 nm (SEM micrographs). The permeability of the filter was low, in order of 10–9 m2. The activity against pathogens was tested in loco in a real environment using a filtration prototype apparatus. It was observed that the presence of CuNP mitigated the fungi and bacteria growth not only on the surface but also reduced microbe concentrations after passing through the filter. These results show that CuNP can be used as an inhibitor of various microorganisms, making them a good alternative for indoor environments to control indoor air quality.

Abstract
BackgroundChronic inflammation in psoriatic arthritis (PsA) may trigger both peripheral and central sensitization via central modifications of pain pathways that can lead to disconnection between tender and swollen joint count. This can result in increased difficulties for the clinician in the assessment of the disease and response to treatment.ObjectivesTo study the impact of tender to swollen joint count ratio (TSR) on treatment response to a first course of biologic disease-modifying antirheumatic drug (bDMARD) therapy in PsA patients.MethodsObservational study including PsA patients under bDMARD, followed with clinical and laboratory examination at baseline, 6 and 12 months of treatment. All patients meet the CASPAR classification criteria. TSR was defined as the tender joint count divided by the swollen joint count, using the 68/66 joint assessment. Patients with no tender nor swollen joints at baseline were excluded. TSR was categorized into 3 groups, based on the empirical distribution, with cuts corresponding to the 20th and 70th percentiles. Disease activity was assessed using the Clinical Disease Activity Index (CDAI), the Simplified Disease Activity Index (SDAI) and Disease Activity Score based on 28 joints (DAS28-CRP(4)). Individual time profiles were plotted within each TSR group. CDAI, SDAI and DAS28-CRP(4) individual time profiles within each TSR group were modelled by mixed-effects linear regression using the TSR group and time as fixed factors and a random factor at the intercept level (accounting for the intra-individual correlation structure). The identification of the statistically significant pairwise differences was obtained from the Tukey’s method for multiple comparisons.ResultsWe included 113 patients, 62 (54.0% females) with a mean age of 48.1±10.8 years-old at the start of the first bDMARD. Sixty-four patients (56.6%) had symmetric polyarthritis, 19 (16.8%) spondyloarthritis, 25 (22.1%) asymmetric oligoarthritis, 2 (1.8%) distal arthritis and 1 (0.9%) arthritis mutilans. Forty-three percent were under corticosteroid therapy and 57.5% under conventional synthetic DMARD (csDMARD) therapy at baseline (mostly methotrexate, in 45.1% of patients under csDMARD). Etanercept (n=35, 31.0%), adalimumab (n=34, 30.1%), golimumab (n=25, 22.1%), infliximab (n=6, 5.3%), certolizumab (5, 4.4%), secukinumab (n=8, 7.1%) were the bDMARD started in these patients. TSR was categorized into 3 groups, namely low [TSR < 1], moderate [1 ≤ TSR ≤ 2.2] and high [TSR > 2.2], with frequencies 15 (13.3%), 66 (58.4%) and 32 (28.3%), respectively. Whenever the number of tender joints was different from 0 and that of swollen joints equal to 0, patients were included in the group high TSR. All TSR groups, with initiation of bDMARD, showed significantly decreases at 6 months in CDAI (low: p=0.006, moderate: p<0.001, high: p<0.001), SDAI (low: p<0.001, moderate: p<0,001, high: p<0.001) and DAS28-CRP(4) (low: p<0.001, moderate: p<0.001, high: p<0.001). From 6 to 12 months of treatment, the differences were not significant in any of the groups (p>0.05). At baseline, CDAI, SDAI and DAS28-CRP(4) means did not differ between groups (p>0.05). There were also no differences in the means of outcome measures at 6 months as well as at 12 months of treatment (p>0.05). Despite this, patients with low baseline TSR had lower mean values of CDAI, SDAI and DAS28-CRP(4) at 6 and 12 months of treatment, consistent with a low disease activity.ConclusionTo our knowledge this is the first study exploring the TSR on treatment response in samples of patients exclusively with PsA. All patients benefited from bDMARD therapy, regardless of the group, suggesting that TSR might not be a good predictor of treatment response in patients with PsA.Disclosure of InterestsNone declared

Abstract
OBJECTIVE Primary bladder melanomas are rare and aggressive neoplasms. We herein described a new case and performed a review of the literature. PATIENTS AND METHODS We present the case of a 81-year-old woman with a primary mucosal melanoma of the bladder after a history of acral melanoma (KRAS mutated) and lentigo maligna of the forehead. Using PubMed, we found that in literature 38 cases were described. RESULTS In our patients, during a transurethral resection (TURBT), two bladder lesions were detected. The histologic exam revealed a malignant melanoma, Mib1/ki67: 10-12%, PDL1 <1%. No BRAF, NRAS or KRAS mutations were detected. She subsequently underwent a transurethral revision of the trigone and a partial cystectomy of the dome with bilateral pelvic lymph node dissection. Microscopical findings showed a residual 5 mm non-muscle-invasive melanoma of the bladder, with negativity of the surgical margins and of the 17 pelvic lymph nodes. No adjuvant treatment was proposed. To date the patient is disease-free. CONCLUSIONS Primary bladder melanoma carries a poor prognosis and poses a therapeutic challenge to clinicians who manage patients with this rare condition. In our experience the multidisciplinary approach for the diagnosis and management of this rare cancer is mandatory.

Abstract
Background:Several studies have shown dissimilar results for the relationship between serum 25-hydroxyvitamin D concentration (25-OH-D) and disease activity in spondyloarthritis (SpA).Objectives:This study aims to assess whether vitamin D levels vary according to disease activity in patients with SpA before and after starting treatment with biologic disease-modifying anti-rheumatic drugs (bDMARDs).Methods:An observational retrospective study was performed in SpA patients followed in the Rheumatology department of a tertiary university hospital. Demographic and clinical data were collected from the Rheumatic Diseases Portuguese Register (Reuma.pt). Patients were assessed for 25-OH-D levels before and after 6 months of treatment with the first bDMARD. Correlation between 25-OH-D levels and disease activity measured by Ankylosing Spondylitis Disease Activity Score (ASDAS) at baseline and after 6 months were assessed using student’s t-test for two samples and one-way ANOVA and with post hoc tests for multiple comparisons.Results:A total of 189 patients were included. Ninety-seven patients were females (51.3%). The mean age at diagnosis was 34.8±11.2 years and the median disease duration at the start of the first bDMARD was 4.9 years (min: 0.1; max: 46.0). All patients fulfilled the ASAS criteria for SpA. Nonsteroidal anti-inflammatory drugs were used by 102 patients (54.0%) and conventional synthetic DMARDs by 69 patients (36.5%). At 6 months, 188 patients were treated with tumor necrosis factor inhibitors and one with interleukin-17 inhibitor. According to ASDAS criteria, at baseline 36.8% of patients had high disease activity and 59.5% had very high disease activity. After 6 months of treatment with bDMARD 14.7% of patients have inactive disease, 21.6% low disease activity, 36.3% high activity and 12.6% very high disease activity. The mean value of 25-OH-D at baseline was significantly lower in the group of patients with very high disease activity compared to the patients with high disease activity (21.9±11.1 ng/ml vs 26.1±11.6 ng/ml, p= 0.02). At 6 months of treatment the mean value of 25-OH-D in inactive, low, high and very high disease activity was 31.0±17.1ng/ml, 28.5±11.2ng/ml, 25.8±10.8ng/ml and 19.3 ±9.5ng/ml, respectively. There was a statistically significant difference between the groups, as determined by one-way ANOVA (p = 0.001). A post hoc Dunnett T3 test revealed that patients with very high disease activity have significantly lower mean 25-OH-D levels (19.29 ± 9.5) than patients with inactive disease (31.0 ± 17.1, p = 0.025) and low activity (28.5 ± 11.2, p = 0.009). Among the groups with high and very high disease activity, the significance is only marginal (p = 0.068).Conclusion:Vitamin D serum concentration varies according to disease activity in SpA. In fact, SpA patients with lower levels of 25-OH-D are associated with higher rates of disease activity, even in patients treated with biologics agents. It is important to be aware of vitamin D level as it can play a role in the management and treatment of the disease, mainly in the most severe patients.References:[1]Zhao SZ, Thong D, Duffield S, Goodson N.

Abstract
Background:The response to treatment in spondylarthropaties is heterogeneous, due to factors yet to be better described. For that reason, it is important to find tools that might help clinicians to decide what is the best available therapeutic option for each patient.Objectives:The goal of this study is to use comprehensive molecular profiling to characterize clinical response to therapy in a real-world setting. Specifically, to identify molecular biomarkers differentiating good responders and non-responders to TNF inhibitors (TNFi) treatment, using adalimumab, in radiographic axial spondyloarthritis | ankylosing spondylitis (r-axSpA|AS) patients context.Methods:Whole-blood mRNA and plasma proteins were measured in a cohort of biologic naïve r-axSpA|AS patients (n = 35) from the Bioefficacy study (Biomarkers identification of anti-TNF alpha agent efficacy in AS patients using RNA sequencing and mass spectrometry), pre and post (14 weeks) TNFi treatment using adalimumab. Response to treatment was categorized according to ASAS20. Results of differential expression analysis were used to identify the most enriched pathways and in predictive models to distinguish responses to TNFi.Results:A treatment-related signature, independent of the type of response, suggests a reduction in inflammatory disease activity. We found genes and proteins robustly differentially expressed between baseline and week 14 in responders, including the GWAS AS-associated genes TNFRSF1A, FCGR2A, TYK2, TBKBP1, IL1R1, IL6R, ICOSLG, IL7R, HHAT and LTBR. Moreover, CRP and HP proteins showed strong and early decrease in the plasma of AS patients, while a cluster of apolipoproteins (APO1, APO2, APO3) showed an increased expression at week 14. Good responders to TNFi treatment tend to have higher expression of innate immunity genes at baseline, and lower expression of markers associated with adaptive immunity, particularly B-cells. A logistic regression model incorporating ASDAS-CRP, gender and Gene x, the top differentially expressed gene at baseline between responders and non-responders, enabled an accurate prediction of response to adalimumab in our cohort (AUC=0.97).Conclusion:Differences in disease activity and/or innate/adaptive immune cell type composition at baseline may be a major contributor to response to adalimumab in r-axSpA|AS. Alternatively, a model including clinical and gene expression variables could be considered, particularly in patients with mild disease activity.Disclosure of Interests:None declared

Abstract
Background:Treatment with teriparatide (TPTD) is associated with reduction of fracture risk in patients with severe osteoporosis. This drug can only be used for up to 2 years. After that a treatment course with antiresorptives should be considered, in order to prevent the rebound of bone turnover observed after TPTD discontinuation. In this regard, interest in sequential osteoporosis therapy has grown in recent years but the ideal timing for starting another treatment after TPTD is not well established.Objectives:The aim of this study is to assess if the timing of onset of antiresorptive therapy after TPTD discontinuation has implications in total hip bone mineral density (BMD) and in fracture risk.Methods:We performed a retrospective cohort study that included patients with severe osteoporosis treated with TPTD 20mcg/day for 24 months and followed for at least 2 more years in the rheumatology department of a tertiary university hospital. For analysis, demographic and clinical data and results of dual-energy X-ray absorptiometry (DXA) after cessation of teriparatide were used. For comparison between groups Mann-Whitney U test was used.Results:Fifty-five patients with osteoporosis, with a median age of 68 (32-85) years, were included. Forty-nine patients were female (89.1%). Nineteen patients (34.5%) had primary osteoporosis and 36 (65.5%) glucocorticoid-induced osteoporosis. The median time for initiating antiresorptive treatment was 7 (0-35) months after cessation of TPTD. Forty-three patients (78.2%) started a bisphosphonate, 6 denosumab (10.9%) and 6 patients did not receive any other treatment. The most prescribed bisphosphonate was zoledronate (69.8%). All patients received calcium and vitamin D supplementation. After completion of TPTD regimen 8 patients experienced at least one fragility fracture (14.5%). At follow-up, 37 (67.3%) of patients underwent DXA on average 30.0±15.4 months after starting antiresorptive agents. The median total hip BMD in patients who started antiresorptive therapy in the first 12 months (inclusive) after cessation of TPTD regime was 0,738 (0.587-0.993) g/cm2 and the median total hip BMD of patients who started therapy after one year of discontinuation of TPTD was 0.683 (0.390-0.813) g/cm2. This difference is marginally significant (p=0.067). The median time in starting antiresorptive treatment is higher in patients with new fragility fractures after TPTD than in patients without new fractures however this difference was not statistically significant (10.0 [2-35] vs 6.0 [0-35] months; p=0.393, respectively).Conclusion:Although this study is unable to show that anti-resorptive treatment should be started in the first year after discontinuation of TPTD, it is promising since the difference between the medians in the total hip BMD values obtained until one year and after one year are marginally significant. These results can be linked to the small sample size and highlight the need for further studies in this area.References:[1]Napoli N, Langdahl BL, Ljunggren Ö, Lespessailles E, Kapetanos G, Kocjan T, Nikolic T, Eiken P, Petto H, Moll T, Lindh E, Marin F.

Abstract
Background We evaluated the efficacy and safety of the nontaxane microtubule dynamics inhibitor eribulin plus the humanized anti-VEGF monoclonal antibody bevacizumab in a novel second-line chemotherapy scheme in HER2-negative metastatic breast cancer (MBC) patients progressing after first-line paclitaxel and bevacizumab. Patients and methods This is a multicenter, single-arm, Simon's two-stage, phase II study. The primary endpoint was the overall response rate, considered as the sum of partial and complete response based on the best overall response rate (BORR). The secondary endpoints were progression-free survival (PFS), overall survival (OS), and clinical benefit rate. Results A total of 58 of the 61 patients enrolled in the study were evaluable for efficacy. The BORR was 24.6% (95% CI 14.5-37.3). The clinical benefit rate was 32.8% (95% CI 21.3-46.0). The median PFS was 6.2 months (95% CI 4.0-7.8), and median OS was 14.8 months (95% CI 12.6-22.8). Overall, adverse events (AEs) were clinically manageable and the most common AEs were fatigue, paresthesia, and neutropenia. Quality of life was well preserved in most patients. Conclusions The results of this study suggest that second-line therapy with bevacizumab in combination with eribulin has a meaningful clinical activity and may represent a potential therapeutic option for patients with HER2-negative MBC. Bevacizumab + chemotherapy improved progression-free survival in HER2-negative metastatic breast cancer (MBC) patients. Eribulin monotherapy improved overall survival in patients with anthracycline- and taxane-pretreated MBC. The GIM11-BERGI trial assessed the efficacy and safety of eribulin + bevacizumab as second-line treatment for HER2-MBC. Eribulin + bevacizumab showed to be a safe and active treatment after progression to first-line paclitaxel + bevacizumab.

Abstract
Background:Spinal mobility is assessed frequently in patients with psoriatic arthritis (PsA) usingBath Ankylosing Spondylitis Metrology Index(BASMI) to provide baseline measurement, monitor changes over time and to assess the impact of clinical interventions. BASMI comprises 4 measures of spinal mobility (cervical rotation, tragus-to-wall distance, modified Schober’s test and lumbar lateral flexion) and one hip mobility measurement (intermalleolar distance).Objectives:The aim of this study is to investigate the time-course change of BASMI in PsA patients after 6 months ofBiologic Disease-modifying Antirheumatic Drug(bDMARD) therapy. The authors also pretend to evaluated, at baseline and after 6 months of treatment, the association between BASMI, disease activity scores and physical function.Methods:An observational retrospective study was performed in patients with PsA under bDMARD followed in the Rheumatology department of a tertiary university hospital. Were included patients treated with only one bDMARD. Demographic and clinical data were collected from the Rheumatic Diseases Portuguese Register. For spinal mobility calculation BASMI was used. Disease activity was evaluated withAnkylosing Spondylitis Disease Activity Score(ASDAS) andBath Ankylosing Spondylitis Activity Index(BASDAI). Physical function was assessed withBath Functional Index(BASFI). The variation of BASMI, ASDAS, BASDAI and BASFI was calculated as the difference between values registered at 6 months and at baseline and presented as Δ. Correlations between ΔBASMI, ΔASDAS and ΔBASFI was calculated using Pearson test.Results:A total of 55 patients were included. Thirty patients were males (54.5%). The mean age at diagnosis was 44.6 ± 12.6 years and the median disease duration at start of bDMARD was 5.4 years (min: 0.30; max: 25.5). In total, 19 (34.5%) patients had predominant axial involvement, 36 (65.5%) peripheric and 36 (65.5%) enthesopathic. Almost all patients fulfilled the CASPAR criteria for PsA (n=50, 90.9%). According to ASDAS criteria, at the baseline 20 patients (36.4%) had high disease activity and 34 (61,8%) very high. The most used bDMARD was etanercept (n=21, 38,3%) followed by golimumab (n=19, 34.5%) and adalimumab (n=8, 14.5%). Three patients were treated with infliximab, two with certolizumab and other two with secukinumab. Forty-one patients (75.9%) were concomitantly treated with conventional synthetic DMARDs. Axial PsA patients had more limitations in spinal mobility (BASMI mean 4.5 ± 1.5) and more functional limitation (BASFI mean 6.8±1.9) than patients with predominant peripheric involvement (BASMI mean 3.3± 1.2, p=0.004; BASFI mean 5.4±3, p=0,0048). Statistically significant differences in ASDAS and BASDAI in these two groups were not observed (p=0.332 and p=0.605, respectively). For all patients, BASMI did not vary significantly (p=0.691) at baseline (mean 3.7± 1.4) and after 6 months (mean 3.8±1.3) of treatment. Although the ΔBASMI for etanercept was negative (mean -0.12±0.9) and for golimumab positive (0.14±0.8), it was not statistically significant. At baseline there is a significant positive association between BASMI and ASDAS (r=0.435, p=0.001), BASMI and BASDAI (r=0.567, p<0.001) and BASMI and BASFI (r=0.510, p<0.001). However, there was not a statistically significant association between ΔBASMI and: ΔASDAS, ΔBASDAI and ΔBASFI (r=0.158; p=0.269, r=0.019; p=0.096 and r=0.121; p=0.397, respectively).Conclusion:In PsA patients treated with bDMARDs, at least in short-term follow-up, BASMI does not improve with time. Changes in BASMI did not correlate with changes in activity disease and in functional outcome. Studies with longer follow-up and with more patients are needed to better evaluate these associations.Disclosure of Interests:Maria Rato: None declared, Filipe Pinheiro: None declared, Salomé Garcia: None declared, Bruno Miguel Fernandes: None declared, Sara Ganhão: None declared, Rita Gaio: None declared, Miguel Bernardes Speakers bureau: Abbvie, Amgen, Biogen, Eli-Lilly, Glaxo-Smith-Kline, Pfizer, Janssen, Novartis, Alexandra Bernardo: None declared, Lúcia Costa: None declared

SAT0482 FRAX 10-YR FRACTURE RISK IN RHEUMATOID ARTHRITIS ASSESSED WITH AND WITHOUT BONE MINERAL DENSITY – ARE WE TREATING OUR PATIENTS UNDER bDMARDs? Ann Rheum Dis 2020.

Abstract
Background:Patients with rheumatoid arthritis (RA) have a higher risk of osteoporosis not only due to chronic inflammation status, but also due to the treatment with glucocorticoids. FRAX is a computer-based algorithm developed by the World Health Organization for estimation of the 10-year risk of a hip or major osteoporotic fracture. Inclusion of femoral neck bone mineral density (BMD) in the estimation is optional.Objectives:The study aimed to identify the RA patients under treatment with biological disease-modifying antirheumatic drug (bDMARD), who have FRAX scores, calculated with and without BMD, classified as high fracture risk and evaluate if they are receiving treatment for osteoporosis. The authors also investigated the intra-individual agreement between FRAX fracture risk calculated with and without BMD.Methods:Demographic and clinical data and BMD results from RA patients followed in a tertiary university hospital and registered in the Rheumatic Diseases Portuguese Register were used for analysis. Patients under 40 years of age at the last visit were excluded. McNemar test was applied for the identification of discordance of risk categories. The Wilcoxon test was used to characterize the intraindividual differences between paired FRAX risks with and without BMD. Correlations between pairs of variables were evaluated by the Spearman test. For independent variables Mann-Whitney test was used.Results:A total of 303 patients were included, 244 were females (80.5%) and 49 current smokers (16.2%). Mean age was 59.5 ± 9.54 years and mean disease duration 18.5 ± 10.4 years. Two hundred and twenty patients (72.4%) and 243 (80.2%) were RF and ACPA positive, respectively, and 51.5% had erosive disease. Mean disease activity score (DAS28-4V-CRP) was 3.08 ± 1.18 and mean femoral neck BMD 0.84 ± 0.12 g/cm2. One hundred and seventy nine patients (58.9%) were concomitantly treated with conventional synthetic DMARDs and 215 (70.7%) with glucocorticoids. Among all the patients, 35 (11.6%) had previous fractures and 19 (6.3%) have family history of fracture. The median 10-year risk of a major fracture and a hip fracture, calculated without BMD, was 6.0 (1.2-50) and 1.5 (0.1-39), respectively; with BMD it was 6.9 (1.3-61) and 1.7 (0-49). When FRAX score is calculated without BMD (n=303), 76 (25.1%) patients were categorized as high fracture risk. Among them, only 41 (54%) were receiving osteoporosis treatment. FRAX assessment with BMD (n=231) identified 99 (32.7%) patients with high fracture risk, 51 (51,5%) in treatment for osteoporosis. Thirty patients (21%) previously classified as low fracture risk using FRAX without BMD were recategorized as high risk (p<0.001). Despite that, there was a strong correlation between fracture risks assessed with and without BMD for both major and hip fracture (r = 0.867, p < 0.0001 and r = 0.728, p < 0.0001, respectively). ACPA and RF positive patients did not have higher FRAX scores (including or not BMA). Patients with erosive disease had a higher 10-year probability of major fracture evaluated by FRAX when it includes BMD (p=0.041).Conclusion:It is very important to accurately assess the risk of osteoporotic fractures in RA patients to treat them properly. The authors highlight the high number of patients who are not receiving treatment according to FRAX categorization. In spite of the correlation between estimated fracture risk by FRAX with and without BMD, there is a discordance in fracture risk categorization, as one fifth of patients of low risk were reclassified as high risk. For the RA population treated with bDMARDS, our findings raise the need to request a DXA not only for patients classified as having an intermediate risk of fracture, but also for low-risk patients.Disclosure of Interests:Maria Rato: None declared, Filipe Pinheiro: None declared, Salomé Garcia: None declared, Bruno Miguel Fernandes: None declared, Sara Ganhão: None declared, Rita Gaio: None declared, Miguel Bernardes Speakers bureau: Abbvie, Amgen, Biogen, Eli-Lilly, Glaxo-Smith-Kline, Pfizer, Janssen, Novartis, Alexandra Bernardo: None declared, Lúcia Costa: None declared

Abstract
Background The activity of palbociclib as a single agent in advanced breast cancer has not been extensively studied, with the only available clinical data limited to heavily pretreated patients. Preclinical data suggests palbociclib may partially reverse endocrine resistance, though this hypothesis has not been evaluated in previous clinical studies. This phase II, open-label, multicenter study examined the activity of palbociclib monotherapy, as well as palbociclib given in combination with the same endocrine therapy (ET) that was received prior to disease progression, in postmenopausal women with moderately pretreated, estrogen receptor-positive, HER2 negative advanced breast cancer. Patients and methods Eligible women with advanced disease which had progressed on one or two prior ETs were randomized 1 : 1 to receive either palbociclib alone, or palbociclib in combination with the ET as previously received. Primary end point was clinical benefit rate (CBR); secondary end points included progression-free survival (PFS). Results Between October 2012 and July 2016, a total of 115 patients were randomized. The CBR was 54% [95% confidence interval (CI): 41.5-63.7] for combination therapy, and 60% (95% CI: 47.8-72.9) for monotherapy. Median PFS was 10.8 months (95% CI: 5.6-12.7) for combination therapy, and 6.5 months (95% CI: 5.4-8.5) for monotherapy [hazard ratio (HR) 0.69; 95% CI: 0.4-1.1, exploratory P-value = 0.12]. Exploratory analyses revealed the PFS advantage for combination therapy was seen in the subgroup of patients who received prior ET for >6 months (HR 0.53; 95% CI: 0.3-0.9, exploratory P-value = 0.02), but not in those who received prior ET for ≤6 months. Conclusion Palbociclib has clinical activity as a single agent in women with moderately pretreated, oestrogen receptor-positive, HER2-negative advanced breast cancer. Palbociclib may have potential to reverse endocrine resistance in patients with a history of previous durable response to ET. Clinical trial information NCT02549430.

Abstract
The leaf rust resistance gene Lr64 in the Thatcher wheat RL6149 was mapped to chromosome 6AL with SNP and KASP markers and a second leaf rust resistance gene was mapped to chromosome 1DS. RL6149, a near-isogenic line of Thatcher wheat, carries leaf rust resistance gene Lr64 on chromosome arm 6AL. The objective of this study was to develop molecular markers that can be easily used to select wheat lines with Lr64. RL6149 was crossed with Thatcher and F2 plants derived from a single F1 plant were advanced to F6 lines by single seed descent. The 100 F7 recombinant inbred lines (RIL) were inoculated with two races of P.triticina that differed widely for virulence in order to identify resistant and susceptible RIL. Thirty RIL that differed for resistance and the parental lines were genotyped with the 90 K Infinium iSelect single nucleotide polymorphism (SNP) array to find closely linked markers with Lr64. Seven linked SNPs on chromosome arm 6AL were converted into Kompetitive Allele Specific PCR (KASP) markers that were genotyped on the 100 RIL. A genetic linkage map for the seven KASP markers spanned 19.1 cM on chromosome arm 6AL. KASP marker K-IWB59855 was tightly linked to Lr64. A second unexpected gene for leaf rust resistance also segregated in the F7 lines. Four KASP markers that spanned 18.6 cM located the gene on chromosome 1DS. The KASP marker K-IWB38437 was tightly linked to the second leaf rust resistance gene.

Abstract
Abstract
Background: At present, there is no standard second-line chemotherapy-based treatment in patients with HER2-negative MBC. Continued VEGF inhibition with bevacizumab is a new potential option in patients progressing to first line bevacizumab and chemotherapy. Eribulin is a non-taxane microtubule dynamics inhibitor, with a unique mechanism of action and suggested beneficial effects on tumor microenvironment and neoangiogenesis. This study evaluated efficacy and safety of eribulin plus bevacizumab as a novel second-line chemotherapy scheme, in patients progressing after first line paclitaxel and bevacizumab.
Methods: This is a multicenter, single-arm, Simon's two-stage, Phase II study. Patients with HER2-negative MBC progressing to paclitaxel and bevacizumab received eribulin (1.23 mg/m2 intravenously on Days 1 and 8 of every 21-day cycle) plus bevacizumab (10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks intravenously), as second-line chemotherapy. The primary endpoint was the overall response rate (ORR), considered as sum of partial (PR) and complete response (CR), basing on the best overall response. The present safety and efficacy analyses, as planned per study design, refer to six cycles of treatment (18 weeks).
Results: Among the 61 patients enrolled in the study, 55 (90,2% ) were evaluable for efficacy. ORR (PR/CR) was 9.1% [95% confidence intervals (C.I.) 3.0 to 19.9]; stable disease (SD) rate was 63.6% [95% C.I. 49.6 to 76.2]; clinical benefit rate (CR/PR/SD) at 24 weeks was 35% [95% C.I. 22.0 to 49.1]. The median progression free survival was 6.3 months [95% C.I. 4.1 to 7.8 months]. Drugs-related adverse events (AEs) were: 49.5% related to eribulin, 7.7% related to bevacizumab, and 11.8% related to both the study drugs. The most common AEs were fatigue (9.9% of all AEs), paresthesia (6.5% of all AEs) and neutropenia (6.2% of all AEs). Quality of life was well preserved among the majority of patients.
Conclusions: The results of our trial suggest that continuing bevacizumab in combination with eribulin, beyond first line treatment with bevacizumab and paclitaxel, offers a reasonable therapeutic option for patients with HER2-negative MBC, without detrimentally affecting quality of life.

Abstract
The widely grown hard red winter wheat cultivar Duster released in 2006 has remained highly resistant to leaf rust caused by Puccinia triticina in the southern Great Plains of the United States. In contrast, many of the winter wheat cultivars in this region are susceptible to leaf rust. The goal of this study was to identify the number and chromosome location of leaf rust resistance genes in a line of Thatcher*2/Duster wheat that was selected for adult plant leaf rust resistance. The Thatcher*2/Duster line was crossed with Thatcher (Tc) and a recombinant line inbred line (RIL) population was advanced to the F6 generation by single-seed descent. The parents and RIL population were phenotyped for leaf rust resistance in three field plot tests and in an adult plant greenhouse test. Single-nucleotide polymorphism (SNP) markers derived from the Illumina Infinium iSelect 90K wheat SNP array, kompetitive allele-specific polymerase chain reaction assays on chromosome 3BL, and a sequence tagged site (STS) marker on chromosome 1BL were used to construct a genetic map of the RIL population. The STS marker csLV46G22 that is linked with resistance gene Lr46 on chromosome 1BL, and SNP marker IWB10344 that is linked with Lr77 on chromosome 3BL, were significantly associated with lower leaf rust severity. Duster has at least three adult plant resistance genes for leaf rust resistance because it was previously determined to also have the adult plant resistance gene Lr34. Duster is a valuable source of durable leaf rust resistance for hard red winter wheat improvement in the Great Plains region.

Abstract
Abstract
BACKGROUND - Metastatic breast cancer (MBC) is a life-threatening disease. It is important to provide data about real-life MBC patients (pts) to understand the current prognostic factors. The aim of the present observational study, named COSMO (Checking Overall Survival in a MBC Observational study) is to describe the overall survival (OS) in a large cohort of MBC pts, assessing its correlation with specific prognostic factors (demographic, clinic, pathologic and biological).
PATIENTS AND METHODS - The COSMO study is a multicenter, retrospective, cohort study, developed throughout the collaboration of 31 Italian oncological centers. Data about pts diagnosed as metastatic from 01/01/2000 to 31/12/2008, were collected. The association between molecular subtypes, metastatic sites, disease free interval (DFI) and OS were assessed. Pts were classified in three subgroups, based on the biological characteristics of their tumor: luminal, HER2-positive (regardless of hormone receptor) and triple negative (TN). Metastatic sites were categorized as visceral versus non-visceral disease, only bone and central nervous system (CNS) metastases. DFI was calculated from diagnosis to first relapse only for M0 pts.
RESULTS - Of 3931 MBC pts enrolled in the study, 3720 were evaluable, with a median age of 61 years (interquartile range, IQR, 51-71). 1804 (62,1%) pts had a luminal disease, 691 (23,8%) HER2-positive, 410 (14.1%) TN. Median DFI was 3.2 years (IQR 1.7- 6.0). Regarding metastatic sites, pts with visceral disease were 2332 (63%); 826 (22,2%) pts had bone isolated metastases; in 306 (8,3%) pts, CNS metastases were reported. With a median follow up of 9 years (IQR 5.7-11.0) and 3098 (83.3%) recorded events, we founded a median OS of 2.8 years (95%CI: 2.7-2.9) years. OS was strictly depending from molecular subtypes with a better prognosis for HER2-positive versus luminal and TN MBC pts, median OS of 3.1 (95%CI 2.8-3.4), 3.0 (95%CI: 2.9-3.1) and 1.5 (95%CI: 1.3-1.7) years respectively (p-value<0.001). 525 (14,1%) pts received trastuzumab. Metastatic sites affect prognosis, with a better OS for bone disease (3.4 years, 95%CI: 3.1-3.6) versus visceral disease (2.2 years 95%CI: 2.0- 2.3). Brain metastasis correlate with the worst prognosis: OS of 1.5 years (95% CI: 0.8 – 1.7). Even DFI shows a correlation with prognosis: pts with DFI>2 years show a median OS of 3 years (95% CI: 2.9 – 3.2), while those with DFI<2 years have a median OS of 2.4 years (95% CI: 2.3-2.6); HR was 0.69 (95%CI: 0,62-0,76) for every five years of increase in DFI (p-value<0.001).
CONCLUSIONS - Molecular subtype is crucial for prognosis: HER2-positive subtype has the best prognosis, while TN subtype has the shorter OS. Having a longer DFI from diagnosis (>2 years) correlate with a better prognosis. Our study confirm that sites of metastasis affects outcome: visceral involvement correlates with poor prognosis and, particularly, pts with brain metastasis represent the worst subgroup, while pts with solely bone disease have the best prognosis. The COSMO study provides a view on the Italian landscape of MBC between 2000 and 2008, adding new insights about pts prognosis.

Abstract
Abstract
Background: W taxanes (T) are commonly used in the treatment of older BC pts, with neurotoxicity (NTX) and fatigue being dose-limiting toxicities with a possible negative impact on function. No prospective data exists on the safety and efficacy of W NP in this population. NP might be of particular value in older pts, due to no need for premedication with steroids and shorter time to recovery from neurotoxicity than conventional T, resulting in a reduced risk of exacerbation of comorbidities such as hypertension and diabetes, and possibly of functional decline (FD). Methods: Pts aged ≥ 65 years (y) with Her-2 negative or Her-2 positive (+), but contraindicated to anti-Her-2 therapy, advanced BC were randomized to receive NP as first-line chemotherapy at either 100 (Arm A) or 125 mg/m2 (Arm B), days 1, 8, 15 q 28. The primary end-point was event-free survival (EFS). An event was either disease progression (PD), death, or FD - defined as a decrease of at least 1 point from baseline values of activities of daily living (ADL) or instrumental ADL (IADL), deemed by the investigator as treatment-related and confirmed at the subsequent cycle. Secondary endpoints included progression-free survival (PFS), response rate (RR) in pts with measurable disease, and incidence of adverse events (AEs). Results: From January 2013 to September 2016, 160 pts were randomized in 15 Italian centres; all but 2 who never started NP were eligible for final analysis. Pts median age was 72y (range 65-84) in Arm A and 73y (range 65-88) in Arm B. Median ECOG performance status was 0 (range 0-2). Baseline IADL impairment was reported in 20 pts (25%) in both arms. >80% pts had ER+ tumors; 2 pts had HER2+ disease. Visceral disease was present in 71% (Arm A) and 70% (Arm B) of pts. Prior exposure to T in the neo/adjuvant setting was 14% (Arm A) and 13% (Arm B). Median number of delivered cycles of NP was 6 (range 1-28 in Arm A, and 1-22 in Arm B), with 3 pts still on treatment. Dose reductions were similarly reported (72% of pts Arm A, 78% of pts Arm B). At a median follow-up of 21 months (mos) (Interquartile range 14-28.4) 140 events were observed. Arm A/Arm B: PD n=53(67%)/n=52(66%); FD n=13(15%)/n=14(18%), death n=3(4%)n=5(6%). Outcomes data are reported in the following table:
Outcomes Arm AArm BMedian EFS, mos (90% CI)6.2 (5.5-8.4)6.4 (5.8-7.7)Median PFS, mos (95% CI)8.3 (5.9-10.5)8.8 (7.4-10.3)RR (95% CI)37% (25-50)42% (30-54)
Fatigue (Arm A: grade (G)2 29%, G3 11%; Arm B: G2 46%, G3 5%) and NTX (Arm A: G2 15%, G3 4%; Arm B: G2 28%, G3 8%) were the most frequently reported AEs. No G4 AEs were reported with the exception of neutropenia (1 pt in arm A) and leucopenia (3 pts in Arm A, 1 pt in arm B). 1 G5 (sepsis) was recorded in Arm B. NTX was reported as the reason for treatment discontinuation in 21 pts (13%) of whom 16 (21%) in arm B. Conclusion: Looking at classical study endpoints (PFS, RR), both doses of NP are active in older pts. However, 17% of pts had to stop treatment due to FD, assessed according to predefined criteria. Due to similar efficacy and reduced NTX, W NP 100 is the suggested dose to be used in older pts with advanced BC.

Abstract
Leaf rust caused by Puccinia triticina is an important disease of wheat in many regions worldwide. Durable or long-lasting leaf rust resistance has been difficult to achieve because populations of P. triticina are highly variable for virulence to race-specific resistance genes, and respond to selection by resistance genes in released wheat cultivars. The wheat cultivar Toropi, developed and grown in Brazil, was noted to have long-lasting leaf rust resistance that was effective only in adult plants. The objectives of this study were to determine the chromosome location of the leaf rust resistance genes derived from Toropi in two populations of recombinant inbred lines in a partial Thatcher wheat background. In the first population, a single gene with major effects on chromosome 5DS that mapped 2.2 centimorgans distal to IWA6289, strongly reduced leaf rust severity in all 3 years of field plot tests. This gene for adult plant leaf rust resistance was designated as Lr78. In the second population, quantitative trait loci (QTL) with small effects on chromosomes 1BL, 3BS, and 4BS were found. These QTL expressed inconsistently over 4 years of field plot tests. The adult plant leaf rust resistance derived from Toropi involved a complex combination of QTL with large and small effects.

Abstract
Docosahexaenoic acid (DHA) is an essential omega-3 fatty acid known to be neuroprotective in several models of human diseases, including multiple sclerosis. The protective effects of DHA are largely attributed to its ability to interfere with the activity of transcription factors controlling immune and inflammatory responses, including the agonist-dependent transcription factor peroxisome proliferator-activated receptor-γ (PPAR-γ). In this study, we used primary oligodendrocyte progenitor (OP) cultures from neonatal rat brain to investigate whether DHA could influence OP maturation and directly promote myelination, as previously reported for selective PPAR-γ agonists. We show that, similarly to the selective PPAR-γ agonist pioglitazone (PGZ), DHA promotes OP maturation and counteracts the maturational arrest induced by TNF-α, used to mimic inflammatory conditions. The PPAR-γ antagonist GW9662 prevented both DHA-induced OP maturation and PPAR-γ nuclear translocation, supporting the hypothesis that DHA acts through the activation of PPAR-γ. In addition, both PGZ and DHA induced the phosphorylation of extracellular signal-regulated-kinase 1-2 (ERK1/2), in a PPAR-γ-dependent manner. ERK1/2 activity is known to regulate the transition from OPs to immature oligodendrocytes and the presence of specific inhibitors of ERK1/2 phosphorylation (U0126 or PD98059) prevented the differentiating effects of both DHA and PGZ. These results indicate that DHA might influence the process of OP maturation through its PPAR-γ agonistic activity and provide novel molecular mechanisms for the action of this dietary fatty acid, further supporting the nutritional intervention in demyelinating diseases such as multiple sclerosis.

Abstract
OBJECTIVE To evaluate the efficacy of tocilizumab (TCZ) on three patients with psoriatic arthritis (PsA) and review the literature for other cases of PsA treated with TCZ. CLINICAL CASES The first patient started TCZ treatment after the failure of adalimumab (ADA), and etanercept (ETA) (Disease Activity Score, DAS28: 6.66) to treat PsA. After 12 months, her DAS28 decreased to 3.26, and at present (24 months), she has achieved disease remission. The second patient started TCZ treatment after the failure of ADA. After 12 months, the DAS28 decreased from 4.90 to 3.99. After 48 months of treatment, the patient had a DAS28 of 3.76. The third case was treated with TCZ after the failure of both infliximab and rituximab therapy. After 12 months, the DAS28 dropped from 8.65 to 5.49. At present, after 37 months of treatment, the patient has a DAS28 of 4.67. In the literature, there are six cases of PsA, which have been treated with TCZ: in two of the cases, the patient showed a great improvement. Two cases failed to achieve disease remission, despite a moderate response to the treatment, and the other two cases showed no improvement. CONCLUSION It can be concluded that TCZ cannot be recommended as an alternative treatment for PsA with predominant peripheral involvement.

Abstract
The patterns and drivers of bacterial strain dominance remain poorly understood in natural populations. Here, we cultured 1292 Bradyrhizobium isolates from symbiotic root nodules and the soil root interface of the host plant Acmispon strigosus across a >840-km transect in California. To investigate epidemiology and the potential role of accessory loci as epidemic drivers, isolates were genotyped at two chromosomal loci and were assayed for presence or absence of accessory "symbiosis island" loci that encode capacity to form nodules on hosts. We found that Bradyrhizobium populations were very diverse but dominated by few haplotypes-with a single "epidemic" haplotype constituting nearly 30 % of collected isolates and spreading nearly statewide. In many Bradyrhizobium lineages, we inferred presence and absence of the symbiosis island suggesting recurrent evolutionary gain and or loss of symbiotic capacity. We did not find statistical phylogenetic evidence that the symbiosis island acquisition promotes strain dominance and both symbiotic and non-symbiotic strains exhibited population dominance and spatial spread. Our dataset reveals that a strikingly few Bradyrhizobium genotypes can rapidly spread to dominate a landscape and suggests that these epidemics are not driven by the acquisition of accessory loci as occurs in key human pathogens.

Abstract
BACKGROUND End-stage renal disease (ESRD) is fatal if untreated. In the absence of transplant, approximately 50 % of dialysis patients die within 5 years. Although more frequent and/or longer haemodialysis (high-dose HD) improves survival, this regimen may add to the burden on dialysis services and healthcare costs. This systematic review summarised the cost effectiveness of high-dose HD compared with conventional HD. METHODS English language publications reporting the cost-utility/effectiveness of high-dose HD in adults with ESRD were identified via a search of MEDLINE, Embase, and the Cochrane Library. Publications comparing any form of high-dose HD with conventional HD were reviewed. RESULTS Seven publications (published between 2003 and 2014) reporting cost-utility analyses from the public healthcare payer perspective were identified. High-dose HD in-centre was compared with in-centre conventional HD in one US model; all other analyses (UK, Canada) compared high-dose HD at home with in-centre conventional HD (n = 5) or in-centre/home conventional HD (n = 1). The time horizon varied from one year to lifetime. Similar survival for high-dose HD and conventional HD was assumed, with the impact of higher survival only assessed in the sensitivity analyses of three models. High-dose HD at home was found to be cost effective compared with conventional HD in all six analyses. The analysis comparing high-dose HD in-centre with conventional in-centre HD produced an incremental cost-effectiveness ratio generally acceptable for the USA, but not for Europe, Canada or Australia. CONCLUSION High-dose HD can be cost effective when performed at home. Future analyses assuming survival benefits for high-dose HD compared with conventional HD are needed.

Abstract
Niemann Pick C 1 (NPC1) disease is an incurable, devastating lysosomal-lipid storage disorder characterized by hepatosplenomegaly, progressive neurological impairment and early death. Current treatments are very limited and the research of new therapeutic targets is thus mandatory. We recently showed that the stimulation of adenosine A2A receptors (A2ARs) rescues the abnormal phenotype of fibroblasts from NPC1 patients suggesting that A2AR agonists could represent a therapeutic option for this disease. However, since all NPC1 patients develop severe neurological symptoms which can be ascribed to the complex pathology occurring in both neurons and oligodendrocytes, in the present paper we tested the effects of the A2AR agonist CGS21680 in human neuronal and oligodendroglial NPC1 cell lines (i.e. neuroblastoma SH-SY5Y and oligodendroglial MO3.13 transiently transfected with NPC1 small interfering RNA). The down-regulation of the NPC1 protein effectively resulted in intracellular cholesterol accumulation and altered mitochondrial membrane potential. Both effects were significantly attenuated by CGS21680 (500 nM). The protective effects of CGS were prevented by the selective A2AR antagonist ZM241385 (500 nM). The involvement of calcium modulation was demonstrated by the ability of Bapta-AM (5-7 μM) in reverting the effect of CGS. The A2A-dependent activity was prevented by the PKA-inhibitor KT5720, thus showing the involvement of the cAMP/PKA signaling. These findings provide a clear in vitro proof of concept that A2AR agonists are promising potential drugs for NPC disease.

Abstract
We describe a case of a young female with lupus that complained about suprapubic pain, dysuria, fever and vomits, symptoms first interpreted as pyelonephritis, despite negative cultures and imaging studies showing hydroureteronephrosis with inflammatory changes. When she developed malar rash, anasarca and nephrotic syndrome, the diagnosis of lupus cystitis with stage IV nephropathy was made, and she started immunosuppressive induction treatment with three pulses of corticosteroids followed by oral prednisolone (60 mg/d) and mycophenolate (1.5 g/d). One month later she was admitted again with blood exams compatible with thrombotic microangiopathy, requiring aggressive immunosuppression and plasma exchange. After overcoming multiple complications, the patient gradually improved, and was discharged with close surveillance. This case poses the question: if the urogenital involvement had been recognized and treated in time, would it prevent the onset of lupus nephritis and other complications?
