Abstract
Carbapenem resistance due to metallo-beta-lactamases (MBLs) is a global phenomenon and an important challenge for antibiotic therapy (Boyd et al., 2020 [1]). While previous reports have demonstrated both in vitro and in vivo synergy using the combination of ceftazidime-avibactam and aztreonam against Stenotrophomonas maltophilia, an MBL-harboring organism, this treatment strategy has not been reported during pregnancy (Mojic et al., 2017 [2], [3], Mojica et al., 2016 [4], Alexander et al., 2020 [5]). We describe a 33-year-old pregnant female with polymicrobial, bilateral pyelonephritis caused by Stenotrophomonas maltophilia and other gram-negative bacteria. The organisms were eradicated with the combination of ceftazidime-avibactam and aztreonam followed by successful delivery with no observed adverse effects in either mother or child post-partum.

Abstract
Purpose/Objective(s) To evaluate the results of LD-RT to lungs in the management of patients with COVID-19 pneumonia. Materials/Methods We conducted a prospective phase I-II trial enrolling COVID-19 patients ≥50 years-old, with bilateral lung involvement at imaging study and oxygen requirement. Patients received 1 Gy to whole lungs in a single fraction. Primary outcome was radiological response assessed as severity and extension scores at days +3 and +7. Secondary outcomes were toxicity (CTCAE v5.0), days of hospitalization, changes in inflammatory blood parameters (ferritin, lymphocytes, C-reactive protein, d-dimer and LDH) and SatO2/ FiO2 index (SAFI), at day +3 and +7. Descriptive analyses were summarized as means with standard deviation (SD) and/or medians with interquartile ranges (IQR). A Wilcoxon sign rank test for paired data was used to assess the CT scores and Chi Square was used to assess for comparison of categorical variables. Results Forty-one patients were included. Median age was 71 (IQR 60-84). Eighteen patients (47%) previously received any antiCOVID treatment (tocilizumab, lopinavir/ritonavir, remdesivir) and thirty-two patients (84%) received steroids during LD-RT. Extension score improved significantly (p=0.02) on day +7 and SAFI on day +3 and + 7 (p<0.01). Median SAFI on day 0 was 147 (IQR 118-264), 230 (IQR 120-343) on day +3 and 293 (IQR 121-353) on day +7. Significant decrease was found in C-reactive protein on day +7 (p=0.02) and in lymphocytes counts on day +3 and +7 (p=0.02). Median number of days in hospital after RT was 11 (range 4-78). With a median follow-up of 60 days after LD-RT, 26 (63%) patients were discharged, 11 (27%) died because of COVID respiratory failure and 4 (10%) died of other causes. Conclusion LD-RT is a feasible and well-tolerated treatment that may lead to rapid clinical improvement. Large randomized trials should be done to establish the efficacy of LD-RT to treat COVID-19 pneumonia.

Abstract
BackgroundThe goal of targeted treatment in patients with Systemic Lupus Erythematosus (SLE) is to achieve clinical remission or low disease activity, with the best quality of life, low damage rates and better survival 1-4. RELESSAR is a multicenter, cross-sectional study registry of ≥18 years SLE (ACR 97) patients 5.ObjectivesTo describe demographic, clinical characteristics and treatments in SLE patients according to disease activity state. To evaluate the proportion of SLE and refractory SLE patients that are potentially candidates for Belimumab treatment (Active SLE despite standard treatment including increased acDNA autoantibodies and low complement).MethodsWe evaluated demographic and clinical data, treatments, score of damage (SLICC), activity (SLEDAI) and comorbidity (Charlson), hospital admissions and severe infections. The patients were compared according to disease activity: remission (SLEDAI = 0 and without corticosteroids), low disease activity (LDA, SLEDAI> 0 and ≤4 and without corticosteroids) and non-optimal control (SLEDAI> 4 and any dose of corticosteroids). Refractory SLE was defined according to Rituximab (RTX) use, non-response to cyclophosphamide or two or more immunosuppressant or splenectomized patients. Potential use of Belimumab according approved prescription in Argentina was analyzed.ResultsOverall, 1277 patients were analyzed: 299 (23.4%) were in remission, 162 (12.7%) in LDA and 816 (63.9%) with non-optimal control of the disease.Patients in non-optimal control group were younger, less frequently female and they showed less time of disease and lower socioeconomic status (p < 0.001). They were also more prevalent mestizos (p= 0.004), had higher SLEDAI and SLICC indexes (p <0.001) and higher use of immunosuppressant therapy (p <0.001). There was no difference regarding biologic treatment (RTX p= 0.547 and Belimumab p= 0.08). This group had higher proportion of hospital admissions and severe infections (p<0.001, respectively).Two hundred and one SLE patients fulfilled the use of Belimumab prescription criteria but only 45/201 patients (22,3%) received it in the last visit. Malar rash was the only clinical variable associated with the use of Belimumab (72.7% vs 29.8% p= 0.005).Seventy-six patients classified as refractory SLE (15.7%) and 56/76 (75.7%) never received Belimumab. Patients on Belimumab therapy were associated to treatment with lower doses of corticoids (p= 0.018) and lower rate of hospital admission caused by SLE flare (p= 0.027).ConclusionA high percentage of patients had uncontrolled disease upon entry into the registry and were potential candidates for treatment with Belimumab. The patients who received biologic treatment showed the benefit of requiring fewer doses of corticosteroids and having a lower rate of hospitalizations.References[1]Mok CC.

Abstract
BackgroundSystemic inflammation in rheumatoid arthritis (RA) seems to accelerate atherosclerosis process and increased cardiovascular (CV) events. An adequate joint inflammation control is correlated with endothelial inflammation (EI) improvement. 18F-fluorodeoxyglucose positron emission tomography with computed tomography (FDG PET/CT) has been shown as a non-invasive, sensitive, and specific tool to show EI. Maximum standardized uptake value (SUV(max)) greater than 1,6 has been correlated with vascular and joint inflammation. Tofacitinib is a Jak inhibitor (JaKi) approved for RA that improves activity and function. The aim of this study is to evaluate the EI outcome by FDG-PET in RA patients treated with tofacitinib.ObjectivesTo assess the EI by FDG-PET/CT in RA patients at baseline and after 12 weeks of tofacitinib treatment initiation.To correlate the vascular findings with disease activity, lipid profile and carotid atherosclerosis by echo Doppler.MethodsProspective, observational study. Inclusion criteria: RA (ACR 2010) patients >18 years old, with high activity score (DAS 28 >3,2) and with biologics or synthetic Dmards requirement by Treat to Target strategy and who tofacitinib was prescribed. Exclusion Criteria: Biologics or Jaki previous use or major CV history known.A baseline Visit evaluating disease activity (DAS 28 and CDAI), functional status by Health Assessment Questionary (HAQ), CV and smoking history, treatments and lipid lab assessment was performed. EI was measured by PET-FDG/CT, showing the SUVmax and target-to-background ratio (TBR) in: right primitive carotid, left primitive carotid, ascendent aorta, descendent aorta and abdominal aorta. Carotid echo Doppler for showing plaque presence was done. During baseline visit tofacitinib was started. After 12 weeks the initial parameters were re-evaluated.ResultsConsecutively, 30 patients were included. Mean age 57 yo (21-79). Female 70%. Mean disease duration 8,3 years (1-40), mean Body mass index (BMI) 24,5. Clinical history: Hypertension 27%, smoking 6,6%, methotrexate treatment 46,6%, methotrexate plus leflunomide 50%, corticosteroids 7,6% (mean dosis 7,6 mg/day).Mean values of DAS 28, CDAI and HAQ were 5.21, 26,6 y 1,56 in baseline and 3,04, 8,80 y 1,09 in the final visit respectively (p:< 0,001 in all comparations) showing statistical significance activity improvement. Echo doppler showed Carotid plaque in 40% of patients without change between visits. Mean cholesterol levels were 188,5 y 207,53 mg/dl in baseline and final visit respectively (p: 0,0039), showing statistical significance. Endothelial uptake by PET-FDG in the 5 areas measured, considering baseline and final visit was: Right Primitive Carotid: SUV Max 2,03 and 1,93 (p: 0,32) and TRB Max 0,94 and 0,85 (p:1,0); Left Primitive Carotid Suv Max 2,07 and 1,94 (p:1,0) and TRB Max 0,92 and 0,90 (p:0,57); Ascendent Aorta SUV Max 2,63 and 2,57 (p:1,0) and TRB Max 1,18 and 1,15 (p:1,0); Descendent Aorta SUV Max 2,77 and 2,57 (p:0,26) and TRB Max 1,27 and 1,17 (p:0,26) and Abdominal Aorta SUV Max 2,59 and 2,43 (p:0,85) and TRB Max 1,15 y 1,11 (p:0,32). None of the endothelial uptake comparisons showed a significant difference between baseline and final visit after 12 weeks.ConclusionThis work shows that, despite the significant improvement in joint activity and function values, there was no modification in EI measured by FDG-PET during tofacitinib treatment along 12 weeks. It is noteworthy that all patients initially presented high inflammatory endothelial uptake values, which reinforces the hypothesis of vascular compromise associated with active joint disease. Studies with more observation time and evaluating the role of different treatments related to endothelium will be of clinical utility in the future.References[1]Rheumatology (Oxford). 2016 Oct;55(10):1777-85.[2]Metabolism. 2017 Feb;67:72-79.[3]Arthritis Res Ther. 2016 May 21;18(1):115.AcknowledgementsPfizer´s unrestricted grantDisclosure of InterestsNone declared

Abstract
The aim of this research was to assess the physico-chemical properties and shelf-life of oils press-extracted at two temperatures (60 °C and 80 °C) from five Peruvian castor bean ecotypes. A wide variation for all traits was observed. Low acidity index, low peroxide index and absence of p-anisidine were recorded. The total tocopherol contents ranged from 798 to 1040 mg/kg. A higher antioxidant capacity was detected in methanolic extracts than in hexane extract. From the Rancimat performed at 150-170 °C, the predicted shelf-life at 25 °C ranged from 0.15 to 8.93 years; the higher extraction temperature led to a longer shelf-life, probably because of enzyme inactivation.

Abstract
BACKGROUND There are only a few studies on handoff quality and adverse events (AEs) rigorously evaluating handoff improvement programmes' effectiveness. None of them have been conducted in low and middle-income countries. We aimed to evaluate the effect of a handoff programme implementation in reducing AE frequency in paediatric intensive care units (PICUs). METHODS Facility-based, cluster-randomised, stepped-wedge trial in six Argentine PICUs in five hospitals, with >20 admissions per month. The study was conducted from July 2018 to May 2019, and all units at least were involved for 3 months in the control period and 4 months in the intervention period. The intervention comprised a Spanish version of the I-PASS handoff bundle consisting of a written and verbal handoff using mnemonics, an introductory workshop with teamwork training, an advertising campaign, simulation exercises, observation and standardised feedback of handoffs. Medical records (MR) were reviewed using trigger tool methodology to identify AEs (primary outcome). Handoff compliance and duration were evaluated by direct observation. RESULTS We reviewed 1465 MRs: 767 in the control period and 698 in the intervention period. We did not observe differences in the rates of preventable AE per 1000 days of hospitalisation (control 60.4 (37.5-97.4) vs intervention 60.4 (33.2-109.9), p=0.99, risk ratio: 1.0 (0.74-1.34)), and no changes in the categories or AE types. We evaluated 841 handoffs: 396 in the control period and 445 in the intervention period. Compliance with all items in the verbal and written handoffs was significantly higher in the intervention group. We observed no difference in the handoff time in both periods (control 35.7 min (29.6-41.8) vs intervention 34.7 min (26.5-42.1); difference 1.43 min (95% CI -2.63 to 5.49, p=0.49)). The providers' perception of improved communication did not change. CONCLUSIONS After the implementation of the I-PASS bundle, compliance with handoff items improved. Nevertheless, no differences were observed in the AEs' frequency or the perception of enhanced communication. TRIAL REGISTRATION NUMBER NCT03924570.

Abstract
Acute physical or psychological stress can elicit adaptive behaviors that allow an organism maintain homeostasis. However, intense and/or prolonged stressors often have the opposite effect, resulting in maladaptive behaviors and curbing goal-directed action; in the extreme, this may contribute to the development of psychiatric conditions like generalized anxiety disorder, major depressive disorder, or post-traumatic stress disorder. While treatment of these disorders generally focuses on reducing reactivity to potentially threatening stimuli, there are in fact impairments across multiple domains including valence, arousal, and cognition. Here, we use the genetically stress-susceptible 129S1 mouse strain to explore the effects of stress across multiple domains. We find that 129S1 mice exhibit a potentiated neuroendocrine response across many environments and paradigms, and that this is associated with reduced exploration, neophobia, decreased novelty- and reward-seeking, and spatial learning and memory impairments. Taken together, our results suggest that the 129S1 strain may provide a useful model for elucidating mechanisms underlying myriad aspects of stress-linked psychiatric disorders as well as potential treatments that may ameliorate symptoms.

Abstract
PURPOSE The state of limited resource settings that Coronavirus (COVID-19) pandemic has created globally should be taken seriously into account especially in healthcare sector. In oncofertility, patients should receive their fertility preservation treatments urgently even in limited resource settings before initiation of anticancer therapy. Therefore, it is very crucial to learn more about oncofertility practice in limited resource settings such as in developing countries that suffer often from shortage of healthcare services provided to young patients with cancer. METHODS As an extrapolation during the global crisis of COVID-19 pandemic, we surveyed oncofertility centers from 14 developing countries (Egypt, Tunisia, Brazil, Peru, Panama, Mexico, Colombia, Guatemala, Argentina, Chile, Nigeria, South Africa, Saudi Arabia, and India). Survey questionnaire included questions on the availability and degree of utilization of fertility preservation options in case of childhood cancer, breast cancer, and blood cancer. RESULTS All surveyed centers responded to all questions. Responses and their calculated oncofertility scores showed different domestic standards for oncofertility practice in case of childhood cancer, breast cancer, and blood cancer in the developing countries under limited resource settings. CONCLUSIONS Medical practice in limited resource settings has become a critical topic especially after the global crisis of COVID-19 pandemic. Understanding the resources necessary to provide oncofertility treatments is important until the current COVID-19 pandemic resolves. Lessons learned will be valuable to future potential worldwide disruptions due to infectious diseases or other global crises.

Abstract
Background:Infectious diseases are increased in patients with rheumatic disorders; vaccination improves morbidity and mortalityObjectives:The aim of this study was to describe the frequency of vaccination in patients with rheumatic disorders and to compare the results with those obtained in 2009 and 2013 in a similar population. We also identified factors leading to lack of vaccination and patients beliefs on vaccines.Methods:Multicentric cross sectional study in patients with autoinmune diseases from external rheumatology offices. Evaluation of vaccination status and patients´ knowledge about vaccines were studied. A comparative analysis was carried out with the series registered in 2009 and 2013 in a similar population.Results:179 patients (158 female, 88.3% and 21 male, 11.7%) were evaluated. Median age was 52 years. Main pathologies were: Rheumatoid Arthritis 65.9% (n:118), Systemic Lupus Erythematosus 11.7% (n:21), Systemic Sclerosis 3.9% (7), Sjogren Syndrome n = 3.4% (n:6), other diseases 15% (n: 27). Median disease duration: 8.87 years. Ninety three percent of patients (n:167) were taking inmunomodulators and 36.8% (n: 66) were using oral corticosteroids (20mg/day or less); 26,8% patients (n: 48) were receiving biological therapies. Vaccination frequency in the population was: Influenza 82% (147); 13-valent conjugate pneumococcal 69.3% (124), 23-valent pneumococcal 64.2% (115) and hepatitis B 62% (111). Comparative with 2009 and 2013 series there was an increase in the rate of vaccinated patients: influenza (82% vs. 39,1% and 74,2% respectively), antineumococcal (64% vs. 17% and 29%) and hepatitis B (62% vs. 6,7% and 26,7%).Reasons for non-vaccination were absence of medical indication (41% of patients for hepatitis B; 32% for 23-valent pneumococcal; 38% for 13-valent pneumococcal and 34% for influenza).139 patients (77, 7%) knew the benefits of vaccines, 164 (91, 6%) thought vaccines are useful; 134 (74,9%) reported that vaccines may decrease dying probability, 155 (86,5%) thought that vaccines are effective to prevent diseases and 149 patients (83,2%) believed that they prevent serious infections. 71 patients (39%) believed that vaccines can lead to serious consequences and 99 (55,3%) that they are more likely to acquire infections than the rest of the population.Conclusion:Frequency of vaccination has increased since 2009 but there is still misinformation regarding vaccines risks and benefits. Promotion and information is essential to improve adherence.References:[1]2019 update of EULAR recommendations for vaccination in adult patients with autoimmune inflammatory rheumatic diseases.

Abstract
Background:Rheumatoid arthritis (RA) affects 0.4-1.3% of general population (1). It can affect lungs in different ways, with interstitial lung disease (ILD) as the most severe. Clinically evident ILD has been reported in 10-42% of patients, with a great impact in prognosis (2).Objectives:Toidentify the prevalence of lung involvement in early rheumatoid arthritis patients (ERA) without previous known lung disease and describe the association between high resolution computed tomography (HRCT), lung functional tests (LFT) and clinical findings.Methods:Cross sectional multicentric study. We included ERA patients (1 year or less since diagnose) consecutively. Patients with previous RA related lung disease or biologic/targeted synthetic Dmard treatment were excluded. HRCT, immunological tests (rheumatoid factor, anti-CCP, ANA), LFT and clinical evaluation were performed.Results:We included 74 patients, 63 (85,1%) woman, mean (SD) of 47 (17,7) years. Thirty-seven patients (50%) were current or former smokers. Abnormal findings in HRCT were found in 62 patients (88,6%): ILD in 6 (8,6%), airway involvement in 40 (70%) and emphysema in 7 (10%). Ten patients (13,5%) had abnormal auscultation (2 sibilances, 2 roncus, and 6 crackles). Six patients (8,1%) had digital clubbing. Regarding immunological tests, 54/61 (88,5%) patients were positive for Anti CCP, and 53/61 (86,9%) were positive for FR. We compared features of patients with findings related to RA in HRCT (interstitial and/or airway) with those without them. We found no differences in the mean (SD) of DAS-28 [4,74 (1,38) vs 4,32 (1,39); p= 0,27]. The prevalence of anti- CCP was not higher in patients with abnormal HRCT [38/44 (86,3%) vs 16/17 (94,1%); p=0,39]. Patients with abnormal HRCT were older [median (IQR) 50,5 years (44,5-59,5) vs 43 years (32-51); p=0,008) and showed higher VSG values [mean (SD) 39,09 (24,03) vs 27,38 (17,6); p= 0,043]. Abnormal physical examination or dyspnea (class 2 mMRC or higher) was significantly associated with HRCT abnormalities [26 (50%) vs 3 (13,6%); p=0.003) and the presence of ILD on HRCT was significantly associated with crackles on the auscultation [4/68(6,25%) vs 2/6 (33,33%); p 0,023].Conclusion:This study shows a high prevalence of lung involvement in ERA patients of less 1 year from diagnosis. Also, we showed a significant association between HRCT and physical examination findings. This data highlights the importance of the clinical examination in Rheumatoid Arthritis patients. More studies with bigger samples and longitudinal follow up are needed to confirm and complete our results.References:[1]Rooney BK, Silman AJ. Epidemiology of the rheumatic diseases.

Abstract
Orofacial clefting is the most common congenital craniofacial malformation, appearing in approximately 1 in 700 live births. Orofacial clefting includes several distinct anatomic malformations affecting the upper lip and hard and soft palate. The etiology of orofacial clefting is multifactorial, including genetic or environmental factors or their combination. A large body of work has focused on the molecular etiology of cleft lip and clefts of the hard palate, but study of the underlying etiology of soft palate clefts is an emerging field. Recent advances in the understanding of soft palate development suggest that it may be regulated by distinct pathways from those implicated in hard palate development. Soft palate clefting leads to muscle misorientation and oropharyngeal deficiency and adversely affects speech, swallowing, breathing, and hearing. Hence, there is an important need to investigate the regulatory mechanisms of soft palate development. Significantly, the anatomy, function, and development of soft palatal muscles are similar in humans and mice, rendering the mouse an excellent model for investigating molecular and cellular mechanisms of soft palate clefts. Cranial neural crest-derived cells provide important regulatory cues to guide myogenic progenitors to differentiate into muscles in the soft palate. Signals from the palatal epithelium also play key roles via tissue-tissue interactions mediated by Tgf-β, Wnt, Fgf, and Hh signaling molecules. Additionally, mutations in transcription factors, such as Dlx5, Tbx1, and Tbx22, have been associated with soft palate clefting in humans and mice, suggesting that they play important regulatory roles during soft palate development. Finally, we highlight the importance of distinguishing specific types of soft palate defects in patients and developing relevant animal models for each of these types to improve our understanding of the regulatory mechanism of soft palate development. This knowledge will provide a foundation for improving treatment for patients in the future.

Abstract
e20062 Background: The increasing incidence and poor outcome associated with MPM demand identification of effective treatment options. Promising results have been reported with immunotherapy (IO) in a small proportion of MPM patients (p). MMR deficiency (dMMR) has been well described in several malignancies and was recently approved as a tumor biomarker for IO with anti-PD-1 checkpoint inhibitor. Next generation sequencing (NGS) data demonstrated that 2% of MPM harbor microsatellite instability. The aim of this study is to characterize MMR by immunohistochemistry (IHC) in a series of MPM p. Methods: Tumors of 159 MPM p from Vall d´Hebron University Hospital and October 12th University Hospital diagnosed between 2002 and 2017 were reviewed. Formalin-fixed, paraffin-embedded tissue was stained for MLH1, MSH2, MSH6 and PMS2 and tumors were classified as dMMR when any MMR protein expression was negative and MMR intact when all MMR proteins were positively expressed. Associations between clinical variables and outcome were assessed with Cox regression models and survival data were calculated by the Kaplan-Meier method. Results: P characteristics: median age: 69 years (29-88 years), males: 71%, performance status (PS) 1:69%, asbestos exposure: 52%, stage III at diagnosis: 42%, epithelial subtype: 65%, systemic treatment 81% (57% chemotherapy with cisplatin plus pemetrexed in first line), 50% received second line and 28% third line. MMR protein expression was analyzed in 158 samples with enough tissue and was positive in all of the cases. The median overall survival (mOS) in all population was 15 months (m) (13.5-18.8m). In a multivariate model factors associated to improved mOS were PS 0 vs PS2 (13 v 2 m, HR 12.8, p < 0.01), neutrophil-lymphocyte ratio (NLR) < 5 (18 v 9 m in NLR ≥5,HR 1.5, p < 0.05) and epitheliod vs sarcomatoid histology (18 vs 4 m HR 4.7, p < 0.01). Thirteen p received IO with anti-CTLA4 or anti-PD-1 blockade in clinical trials, 58% had a response or stable disease for more than 6 m, with median progression-free survival (PFS) of 5.7 m (2.1-26.1m). Conclusions: In our series we were unable to identify any MPM patient with dMMR by IHC. Further studies are needed to elucidate novel predictive biomarkers benefit from IO in MPM.

Abstract
BACKGROUND In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS This was a multicenter, open-label, phase I-II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day ‒1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. RESULTS A total of 66 patients were recruited (median age 36 years; range 18-66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3-4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3-4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2×10e6/kg CD34+ cells (median 5.75; range 2.12-33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). CONCLUSION BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival.

Abstract
Whether or not one can detect relict signatures of the past imprinted in current landscapes is a question of the utmost theoretical and practical relevance for meandering tidal channels, owing to their influence on the morphodynamic evolution of tidal landscapes, a critically fragile environment, especially in face of expected climatic changes. Unravelling the sedimentary patterns of ancient channels is an expensive process that usually requires high resolution sediment coring. Here we use a novel inversion process of multi-frequency electromagnetic measurements to reveal the signature and characterize the dynamics of a salt-marsh paleo-meander in the Venice Lagoon. We show that the ancient meander migrated laterally while vertically aggrading, developing a peculiar bar geometry which is less common in analogous fluvial meanders. The observed point-bar dynamics and the associated architectural geometry are consistent with remote sensing and borehole data and contrast with current assessments of tidal meander morphodynamics mediated from classical fluvial theories. In addition, the proposed technique, rapid and non-invasive, bears important consequences for detecting buried stratal geometries and reconstructing the spatial distribution of ancient sedimentary bodies, providing quantitative data for the description of landscape evolution in time.

Abstract
Honeybees are threatened by various pathogens and parasites. More than 18 viruses have been described in honeybees and many of them have been detected in China and Argentina. In China, both Apis cerana and Apis mellifera are raised. In Argentina, beekeepers raise different ecotypes of A. mellifera: European honeybees (in both temperate and subtropical regions) and Africanised honeybees (in subtropical areas only). A thorough study was carried out in both China and Argentina to analyse the current virus presence and distribution in different climatic zones and gather information on different bee species/subspecies. Adult honeybees were collected from apiaries in temperate and subtropical regions of China (including areas with exclusive populations of A. mellifera, areas where A. mellifera and A. cerana co-exist, and areas with exclusive populations of A. cerana) and Argentina. Six viruses, namely, deformed wing virus (DWV), black queen cell virus (BQCV), sacbrood virus (SBV), chronic bee paralysis virus (CBPV), acute bee paralysis virus (ABPV) and Israeli acute paralysis virus (IAPV) were detected in China, both in A. cerana and in A. mellifera, while four viruses (DWV, BQCV, CBPV and ABPV) were present in Argentina. Interestingly, multiple infections were commonly found in China, with up to five different viruses co-circulating in some colonies without apparent abnormalities. In this study, no Chinese samples were positive for slow bee paralysis virus. The most prevalent viruses were BQCV (China) and DWV (Argentina). Kashmir bee virus was absent from samples analysed for both countries.

Abstract
La valutazione non invasiva della dominanza emisferica per il linguaggio è una delle più promettenti applicazioni cliniche della risonanza magnetica funzionale, specie nei pazienti destinati alla neurochirurgia. In questo studio sono state eseguite due prove linguistiche in un gruppo di giovani volontari sani (8 destrimani, 12 non destrimani): una di fluenza fonemica ed una di associazione semantica. Tra i voxels statisticamente attivati nei due emisferi sono stati calcolati tre indici di asimmetria (emisferico, frontale e temporoparietale) in ogni soggetto e per ogni prova. Nel complesso, la prova di fluenza fonemica attivava fortemente il lobo frontale, mentre la prova di associazione semantica determinava un pattern di attivazione piu distribuito, che comprendeva anche il giro temporale medio ed il giro angolare. Per quanto riguarda gli indici di asimmetria, nei destrimani quello emisferico e quello frontale indicavano sempre l'attivazione prevalente dell'emisfero sinistro. Un solo soggetto ambidestro ha presentato nella prova di fluenza fonemica indici di asimmetria emisferico e frontale espressivi di lateralizzazione destra. D'altra parte, l'indice di asimmetria temporoparietale deponeva per una lieve revalenza dell'emisfero destro in un destrimane ed per una chiara lateralizzazione destra in un non destrimane. La risonanza magnetica funzionale appare dunque metodica sensibile ed appropriata nella valutazione della dominanza emisferica per il linguaggio. L'impiego di indici di asimmetria lobari può meglio evidenziare il differente contributo alla dominanza emisferica delle aree frontali rispetto a quelle temporoparietali. Infine, l'individuazione delle aree corticali correlate con la funzione linguistica è uno strumento potenzialmente utile per il neurochirurgo nel programmare resezioni di aree limitrofe.

Abstract
BACKGROUND/OBJECTIVES Blood polyunsaturated fatty acids (PUFA) are involved in allergy development, but the etiological role of n-6 and n-3 PUFA is still controversial. A European multicenter study of children (IDEFICS) provided the opportunity to explore the cross-sectional association between fatty acids (FA) and allergy. SUBJECTS/METHODS Blood FA levels were measured in 2600 children aged 2-9 years and were recorded as the percentage of weight of all FA detected. Logistic regression of allergy status on FA components was adjusted for age, sex, country, body mass index, family history of allergic disease, breast-feeding, and number of siblings. The results were given as odds ratios (OR) for current vs no allergy ever and an increase in FA by 1 s.d. RESULTS Overall, higher proportions of n-6 PUFA were associated with higher odds of allergy (OR=1.21 (1.05, 1.40)). Monounsaturated FA (MUFA) were associated with reduced risk for allergy (OR=0.75 (0.65, 0.87)), whereas saturated FA did not differ by allergy status. The strongest associations were observed in children <4 years old, with ORs of allergy given as 1.62 (1.15, 2.29) for n-3 PUFA and 0.63 (0.42, 0.95) for MUFA. With regard to individual FA, these associations were independently observed for docosapentaenoic acid (22:5 n-3) and oleic acid (18:1 n-9). CONCLUSIONS Both PUFA subtypes were positively associated with allergy in an age-dependent manner, whereas MUFA was associated with less allergy. The observation of high proportions of n-3 PUFA in allergic children younger than 4 years might help to understand the nature of early onset of atopic disease.

Abstract
A recently developed spatial operator algebra for manipu lator modeling, control, and trajectory design is dis cussed. The elements of this algebra are linear operators whose domain and range spaces consist of forces, moments, velocities, and accelerations. The effect of these operators is equivalent to a spatial recursion along the span of a manipulator. Inversion of operators can be efficiently obtained via techniques of recursive filtering and smoothing. The operator algebra provides a high- level framework for describing the dynamic and kinematic behavior of a manipulator and for control and trajectory design algorithms. The interpretation of expressions within the algebraic framework leads to enhanced concep tual and physical understanding of manipulator dynamics and kinematics. Furthermore, implementable recursive algorithms can be immediately derived from the abstract operator expressions by inspection. Thus the transition from an abstract problem formulation and solution to the detailed mechanization of specific algorithms is greatly simplified.

Abstract
Forkhead box protein 3 (FoxP3)(+) regulatory T cells (Tregs ) are important not only in regulating the development of autoimmune conditions, but also in chronic infectious diseases. Given their cardinal function in suppressing immune activation, research has focused upon whether they play a detrimental role in chronic infections, particularly HIV. While the role of Tregs in HIV has been investigated intensively, it remains an unresolved topic. However, it is generally accepted that Tregs are susceptible to HIV infection and are preferentially preserved over conventional CD4(+) T cells. It is unknown whether the peripheral-induced or the thymic-derived Tregs are more susceptible to HIV cytotoxicity. It has been recognized that Tregs can be segregated into two subsets based on Helios expression, with the vast majority being Helios(+) . This study examines the impact of HIV infection on total Tregs and their Helios subsets in a perinatal-acquired HIV-infected paediatric population. The finding indicates a selective expansion or survival of Tregs in association with CD4 depletion and increased viraemia. The Helios(+) and Helios(-) subsets within Tregs appear to be equally affected. However, the Helios(+) Tregs seem to be more preserved in patients with low CD4(+) ≤ 25% and detectable plasma HIV RNA >20 copies/ml. In this group, the frequencies of Tregs are increased, but their numbers appear insufficient to restrain immune activation. In conclusion, our findings suggest that both Helios subsets of Tregs are susceptible to HIV infection and are preferentially preserved compared to conventional CD4(+) T cells.

Abstract
The preliminary results are reported for a systematic computerized analysis of interictal EEG recordings from patients with different epileptic syndromes. Both interical specific epileptic activity and non-specific background EEG signals are processed by special programs. Specific achievement are: a) Automatic recognition of spikes and quantification in every channel of their temporal incidence; b) definition of morphology and temporal relationship among spikes simultaneously recorded from different cortical and subcortical structures. Non-specific achievement: a) Characterization of background pattern; b) identification, quantification and localization of pathological frequencies. The study of changes in the described parameters induced by pharmacological therapies and measured drug plasma levels, has supplied additional criteria for the evaluation of epileptic dynamics and the monitoring of optimal treatment modes.

Abstract
In-depth interviews conducted separately with 13-year-olds with autism spectrum disorder (ASD), intellectual disability (ID), or typical development (TD) and their mothers investigated the experiences of victimization in the form of bullying. Coded constructs from the interviews were utilized to compare groups on the frequency, type, and impact of victimization. Youth with ASD were victimized more frequently than their ID or TD peers, and the groups differed with regard to the type of bullying and the impact it had, with ASD youth faring the worst. Higher internalizing problems and conflict in friendships were found to be significant predictors of victimization, according to both youth- and mother-reports. These predictors were found to be more salient than ASD status alone. Implications for practice are discussed.

Abstract
The Y155H amino acid substitution in the neuraminidase gene (NA) has previously been associated with highly reduced inhibition by neuraminidase inhibitors in the seasonal H1N1 influenza A virus which circulated in humans before the 2009 pandemic. During the 2012/13 epidemic season in Spain, two A(H1N1)pdm09 viruses bearing the specific Y155H substitution in the NA were detected and isolated from two patients diagnosed with severe respiratory syndrome and pneumonia requiring admission to the intensive care unit. Contrary to what was observed in the seasonal A(H1N1) viruses, neither of the Y155H A(H1N1)pdm09 viruses described here showed a phenotype of reduced inhibition by NAIs as determined by the neuraminidase enzyme inhibition assay (MUNANA). High-throughput sequencing of the NA of both Y155H viruses showed that they were composed to >99% of H155 variants. We believe that this report can contribute to a better understanding of the biological significance of amino acid substitutions in the neuraminidase protein with regard to susceptibility of influenza viruses to neuraminidase inhibitors. This is of critical importance for optimal management of influenza disease patients.

Abstract
Nutrient removal from primary wastewater effluent was tested using Galdieria sulphuraria, an acidophilic and moderately thermophilic alga. Biomass yield recorded in this study (27.42g biomass per g nitrogen removed) is higher than the average reported in the literature (25.75g g(-1)) while, the theoretical yield estimated from the empirical molecular formula of algal biomass is 15.8g g(-1). Seven-day removal efficiencies were 88.3% for ammoniacal-nitrogen and 95.5% for phosphates; corresponding removal rates were 4.85 and 1.21mg L(-1)d(-1). Although these rates are lower than the average literature values for other strains (6.36 and 1.34mg L(-1)d(-1), respectively), potential advantages of G. sulphuraria for accomplishing energy-positive nutrient removal are highlighted. Feasibility of growing G. sulphuraria outdoors at densities higher than in high-rate oxidation ponds is also demonstrated.
