Abstract
Background:Tofacitinib is an oral JAK 1 and 3 inhibitor for the treatment of moderate to severe active rheumatoid arthritis (RA) or psoriatic arthritis (PsA) in adults with inadequate response or intolerant to one or more conventional disease-modifying antirheumatic drugs (cDMARDs). Since its approval by the European Medicines Agency (EMA), there is limited data about its use in daily practice in Europe.Objectives:To describe rates and reasons for discontinuation of Tofacitinib in patients with RA and other inflammatory conditionsMethods:We identified patients with a prescription for tofacitinib at our academic center from January 2017 to January 2020. Patients were treated according to their rheumatologist evaluation following standards of care. The following variables were retrospectively collected from the electronic medical chart: age, gender, diagnosis, date of treatment initiation, date and reasons for treatment discontinuation, the use of concomitant or previous cDMARDs and of biologics. A comparison between patients continuing and stopping tofacitinib was performed through chi2or t-test for qualitative and quantitative variables, respectively. Survival analysis was done by Kaplan-Meier methodResults:Ninety patients receiving tofacitinib were identified, 81 with RA, 6 with PsA, 1 with Dermatomyositis, 1 with Sjögren´s and 1 with juvenile idiopathic arthritis. Table 1 shows the baseline characteristics. 84% percent patients were women and the mean (SD) age was 58.5 (14.2) years. 51% patients started tofacitinib in monotherapy. When used, methotrexate was the most frequent cDMARD (61.3%); 10% patients used tofacitinib as first line after cDMARD and the majority used it after 1 or 2 previous biologics (46.7%).Table 2.Clinical coutcome of patients who developed HZ at initiation of baricitinibAll patients(n=90, 100%)Continue Tofacitinib(n=58; 64%)Not continue Tofacitinib(n=32; 35.5%)p-valueFemale (%)76 (84.4)48 (82.7)28 (87.5)0.55Age (year) – mean (SD)58.5 (14.2)58 (12.9)59.5 (16.5)0.63Diagnosis0.66Rheumatoid arthritis81 (90)52 (89.6)29 (90.6)Psoriatic arthritis6 (6.7)4 (6.8)2 (6.2)Other3 (3.3)2 (3.4)1 (3.1)Treatment duration (months) – mean (SD)10.6 (6.9)11.9 (7.3)8.2 (5.5)0.02Prednisone (mg) – mean (SD)1.75 (3.2)1.20 (2.5)2.73 (4.1)0.03Monotherapy (%)46 (51.1)28 (48.2)18 (56.2)0.244Concomitant csDMARDs (%)44 (48.8)30 (51.7)14 (43.7)0.62Methotrexate (%)27 (30)17 (29.3)10 (31.2)Leflunomide (%)10 (11.1)8 (13.7)2 (6.2)Other (%)7 (7.7)5 (8.6)2 (6.2)Prior biologic treatment0.13None (%)9 (10)6 (10.3)3 (9.3)1-2 (%)42 (46.6)28 (48.2)14 (43.7)≥3 (%)39 (43.3)24 (41.3)15 (46.8)Survival rates when used as first or second line were 85% at 6 months and 70% at 12 months; when used as third line or further, 76% and 70%, respectively (graphic 1).Factors associated to tofacitinib discontinuation were treatment duration and baseline prednisone dose. In contrast concomitant csDMARD and number of previous biologics were not. Reasons for tofacitinib discontinuation were: lack/loss of efficacy 46.9%, adverse events 50% (including intolerance -22%- herpes zoster -16%-, other infections 12%) and others.Conclusion:Tofacitinib in our experience is mostly used in RA patients after biologic failure. Overall survival rate at 12 months was good regardless line of therapy. Adverse event rates were similar to other biologic treatments. Herpes zoster was the most common infectious AE.Graphic 1:References:[1]Wollenhaupt J, Lee EB, Curtis JR, et al.

Abstract
Background:Patients with inflammatory arthralgia (IA) are considered to be at increased risk for progression to RA. US has shown high sensitivity to detect synovitis compared with physical examination. Thus, US is recommended to identify subclinical synovitis in patients without clinical signs of inflammation.Objectives:The objective of our study is to determine the frequency and pattern of US detected inflammatory findings in patients with IA and investigate factors contributing to predict these findings.Methods:An US clinic is scheduled in an academic center running three days every week. A retrospective analysis of our US unit cohort during a period of 6 months was undertaken. Patients with IA and no previous diagnosis of inflammatory arthropathies were included for analysis. Inclusion criteria of IA definition included: severe symptoms presenting in the morning, duration of morning stiffness ≥60 min, symptoms predominantly located in MCP joints and abscense of clinically detected synovitis by the referral rheumatologist. The following routinely collected variables were included in the analysis: demographics, clinical features and laboratory tests. Patients underwent bilateral US examination in GS and PD mode of hands and/or feet according to the European League Against Rheumatism (EULAR) guidelines. The presence of synovitis, tenosynovitis and enthesitis was assessed on a semi quantitative scale (0–3) for Grey Scale(GS)/Power Doppler(PD) or using enthesitis OMERACT definition, respectively. Patients were stratified in two groups based on the presence of US inflammatory findings (synovitis, tenosynovitis or enthesitis with PD signal). First, differences between groups were tested using chi-squared and Student-t tests in the univariate analysis. Second, multivariate logistic regression models were employed to investigate the association between possible predictive factors of US detected inflammatory findings.Results:A total of 57 patients were included in the analysis. Mean age was 55.8±15.2 years, 41 (71.9%) were females, and mean symptoms duration was 11.4±10.4 months (Table 1). A total of 42 (73.7%) patients presented with a polyarticular arthralgia pattern. US inflammatory findings were present in 20 (35.1%) patients (26.3% PD synovitis, 21.1% PD tenosynovitis and 3.5% PD enthesitis). Hands were most commonly involved with PD synovitis at wrists in 19.3% and at MCP in 12.3% of patients (Table 2). For PD tenosynovitis, the flexor MCP 2-5 (5.3%) and compartment IV tenosynovitis (1.8 %) were the most frequent affected locations. Only two patients had PD enthesitis at feet and 6 (10.5%) had erosions in hands or feet at baseline examination. In the univariate analysis, the higher ESR values and the shorter time from symptoms onset were significantly associated with US detected inflammatory findings (p=0.044 and 0.049, respectively). In the multivariate analysis, only ESR values (OR=1,04; 95%CI 1,002-1,078), remained significantly associated with the presence of US inflammatory findings (Table 3).Table 3.Independent predictors of US detected inflammatory findingspOdds ratio95% C.I.LowerUpperESR (mm/h)0.0391.041.0021.078Time (months) from symptoms onset0.10.9240.8411.015Conclusion:PD US inflammatory findings are found in 1 over 3 patients with IA being PD synovitis the most common finding, specially at the wrists and MCP joints. Higher ESR values were significantly associated with the presence of US inflammatory findings. Our data highlights how the use of PD US may be useful to detect subclinical synovitis in patients with IA.Disclosure of Interests:Katerine López Gloria: None declared, Isabel Castrejon: None declared, Laura Trives Folguera Speakers bureau: ROCHE, Juan Carlos Nieto Speakers bureau: Pfizer, Abbvie, MSD, Novartis, Janssen, Lilly, Nordic Pharma, BMS, Gebro, FAES Farma, Roche, Sanofi, Belén Serrano Benavente: None declared, Julia Martínez-Barrio Consultant of: UCB Pharma, Javier Rivera: None declared, Carlos Gonzalez Consultant of: Gilead, Janssen, Novartis,, Speakers bureau: Abbvie, Celgene, Gilead, Janssen, Novartis, Pfizer, Roche, Indalecio Monteagudo: None declared, Jose-Maria Alvaro-Gracia Grant/research support from: Abbvie, Elli-Lilly, MSD, Novartis, Pfizer, Consultant of: Abbvie, BMS, Janssen-Cilag, Elli-Lilly, MSD, Novartis, Pfizer, Sanofi, Tigenix, Roche, UCB, Paid instructor for: Elli-Lilly, Pfizer, Roche, Speakers bureau: Abbvie, BMS, Janssen-Cilag, Elli-Lilly, Gedeon Richter, MSD, Novartis, Pfizer, Sanofi, Tigenix, Roche, UCB, Juan Molina Collada: None declared

Abstract
Background:Patients with immunity mediated inflammatory diseases (IMID) often have clinical manifestations and comorbidity in the field of various medical specialties. A center has been created in our hospital for the comprehensive care of patients with IMID who are being treated with biological therapies (BT) or targeted synthetic molecules (TSM). It is an innovative healthcare model, that incorporate patients into its governance. Physicians, pharmacists and advanced practice nurses (APN), collaborates in consultation or in the day hospital (DH).Objectives:To analyze the activity developed during the first year of operation of the center, with special attention to effectiveness, efficiency, interdisciplinary relationships and patient satisfaction.Methods:Observational analysis with indicators of management and monitoring of patients, care activity, effectiveness, adverse effects, resource consumption and patient satisfaction using the hospital’s own information systems.Results:Center staff during 2019: two admission assistants, one nursing assistant, six nurses, seven part-time doctors and three pharmacists. 1,490 patients were included: 694 (46.6%) Rheumatology (Rheu), 585 (39.3%) Digestive (Dig) and 211 (14.1%) Dermatology (Der) generated 11,363 medical consultations, 14,850 APN consultations and 3,920 treatment sessions in the DH. IV treatment 529/1490 (35.5%) patients (45.0% Reu, 53.9% Dig, 1.1% Der). Patients with rheumatic diseases: rheumatoid arthritis: 339/694, 48.8%; Spondyloarthritis: 226/694, 32.6%; psoriatic arthritis: 117/694, 16.9%; and juvenile idiopathic arthritis: 12/694, 1.7%. 217/1490 (14.6%) patients needed multidisciplinary consultations.Table 1. shows the most relevant indicators and table 2 shows the patient satisfaction survey for 2019.Table 1.relevant indicatorsRHEUDIGDEROn demand consultations 2019 %21.0%34.2%14.3%Teleconsultations 2019 %17.8%41.9%0.0%BT, TSM tapering. %201931.9%0.2%45,5%201818.9%0.2%13.4%BT, TSM intensification. %20195.8%35.2%0.5%20182.6%36.5%0.5%Biosimilars %201943.1%48.5%15.9%201830.4%4.0%12.1%Adherence>90% 2019 %89.4%91.7%86.4%Remission 2019 %47.8%67.3%78.5%hospital admission, any cause pat-years20191.41.70.120181.51.50.04emergency admission, any cause pat-years20192.12.11.620182.12.01.5Table 2.patient satisfaction surveyCategoríaMean and (DS) 1-5General aspects of the center4.3 (0.9)Physicians4.5 (1.1)DH and APN4.5 (1.2)Pharmacy4.6 (0.9)Health proffesional coordinaton4.4 (0.9)Hospital global satisfaction4.3 (0.8)Conclusion:From previous situation there is an increase in interdisciplinary consultations and HD activity maintenance without an increase in human resources. Efficiency (tapering, biosimilars) and patient and staff satisfaction have improved. However, no improvement in adverse effects has been observed, which is an area of improvement. Effectiveness is good, waiting to compare with the previous year. Nutrition and preventive medicine consultations has not been evaluated because have been recently established. Other indicators are being analyzed at the end of the submission deadline.The impact of this pioneering management model, with a holistic approach and incorporating patients into its governance, is difficult to measure until its implementation is completed. Uveitis and psychology consultations and patient school starting in 2020 will improve the quality of IMID patient care, as well as their satisfaction and that of their relatives.Disclosure of Interests:Carlos Gonzalez Consultant of: Gilead, Janssen, Novartis,, Speakers bureau: Abbvie, Celgene, Gilead, Janssen, Novartis, Pfizer, Roche, Luis Alberto Menchén Viso Grant/research support from: Abbvie, Janssen, MSD, Takeda, Consultant of: Abbvie, Janssen, Takeda, MSD, Medtronic, Tillotts, Pfizer, Dr. Falk Pharma, Speakers bureau: Abbvie, Janssen, Takeda, MSD, General Electric, Tillotts, Pfizer, Ferring, General Electric, Fresenius, Ofelia Baniandrés Rodríguez: None declared, Ignacio Marín-Jiménez Consultant of: AbbVie,Chiesi,FAES Farma,Falk-Pharma,Ferring,Gebro Pharma, Hospira,Janssen,MSD,Otsuka Pharmaceutical,Pfizer,Shire,Takeda,Tillots and UCB Pharma, Speakers bureau: AbbVie,Chiesi,FAES Farma,FalkPharma,Ferring,Gebro Pharma,Hospira,Janssen,MSD,Otsuka Pharmaceutical,Pfizer,Shire,Takeda,Tillots and UCB Pharma, Juan Carlos Nieto Speakers bureau: Pfizer, Abbvie, MSD, Novartis, Janssen, Lilly, Nordic Pharma, BMS, Gebro, FAES Farma, Roche, Sanofi, Indalecio Monteagudo: None declared, Arantza Ais Larisgoitia: None declared, Esther Chamorro de Vega: None declared, Elena Lobato Matilla: None declared, Rosa Romero Jiménez: None declared, Ana Herranz Alonso: None declared, Carmen Lobo Rodríguez: None declared, María Prado Simón Moreno: None declared, Jose-Maria Alvaro-Gracia Grant/research support from: Abbvie, Elli-Lilly, MSD, Novartis, Pfizer, Consultant of: Abbvie, BMS, Janssen-Cilag, Elli-Lilly, MSD, Novartis, Pfizer, Sanofi, Tigenix, Roche, UCB, Paid instructor for: Elli-Lilly, Pfizer, Roche, Speakers bureau: Abbvie, BMS, Janssen-Cilag, Elli-Lilly, Gedeon Richter, MSD, Novartis, Pfizer, Sanofi, Tigenix, Roche, UCB, Sonia García de San José: None declared

Abstract
Background:Metotrexate (MTX) is usually the first line therapy for Rheumatoid Arthritis (RA) because of its favorable efficacy-toxicity ratio. However the exact mechanism and treatment response time in both a clinical and ultrasonographic setting are still uncertain.Objectives:To describe the clinical and ultrasound response to MTX during the first 6 months of treatment in early RA patients who started subcutaneous methotrexate as the first disease-modifying drug (DMARD).Methods:Ongoing prospective cohort of patients with early RA (ACR-EULAR 2010 criteria), over 18 years and starting MTX-SC. Patients had a clinical and ultrasonographic evaluation at baseline, 1, 3 and 6 months. We collected demographic data, C-reactive protein [CRP], erythrocyte sedimentation rate [ESR], rheumatoid factor [FR], anti-citrullinated protein antibody [ACPA]), inflammatory activity indexes (DAS28esr and DAS28crp) and EULAR’s response to treatment (delta value of -1.2 in DAS28 scores). Joints explored with ultrasound were elbows and wrists (radio-carpal and inter-carpal joint) counted as a single joint, 1st-5th metacarpophalangeal (MCF), proximal interphalangeal (IFP), knees, tibio-talar and subtalar joints and 2nd-5th metatarsophalangeal (MTF) joints. Bone erosions were evaluated in 2nd and 5th MCF, styloid, distal ulna and 5th MTF. Synovitis was graduated semi-quantitatively from 0 to 3 (OMERACT) and calculated on B mode and Doppler.Results:35 patients were included (mean age 61.2 years, 65.7% women) with a median of 0.8 (+/-8) months delay to diagnosis. 34 patients (97.1%) started 15mg MTX-SC/weekly. A higher DAS28esr was found in baseline data for the group that had a response by month 1 (DAS28esr baseline 5.5 vs 4.2 p=0.01), no other significant differences were found. During the first month, a significant response was achieved in 13 (41%) patients and remission in 11 (35%) (Table 1). 17 patients have 6thmonth data. 11 (64.7%) have achieved EULAR response compared to baseline(P=0.0005) out of which 7 (54.5%) had already reached it by month 1. A difference in MTX dose (month1 14.8 vs month6 17.1 p=0.003) was found between month 1 and 6, with no differences in disease activity. In the ultrasonographic baseline data; 8 patients (22.9%) had erosions, with a mean of 2,75 erosions/patient (22 of the 280 locations). During the follow up the global rating lowered, with no differences in B mode but significant differences in Doppler at the 6 month mark (Table 2). As of this report, 10 patients (28.5%) had stopped MTX treatment due to lack on response or adverse effects and 8 (22.9%) are waiting 6thmonth evaluation.Table 2.Ultrasound synovitis global rating.BaselineMonth 1P ValueEULAR response013 (41)0.00005MTX Dose mg (SD)14.8 (+/-0.8)14.8 (+/-1.6)1Prednisone Dose mg(SD)5.9 (+/-6.5)2.9 (+/-3)0.02DAS28crp (SD)4.3 (+/-1.5)3,4 (+/-1.4)0.02DAS28esr (SD)(4.8 (+/-1.5)3.7 (+/-1.4)0.006Remission (DAS28<1.2)3(9.6)11(35.5)0.04Table 1.Baseline characteristics of the patients with RA (n=102).BaselineN=351 monthN=313 monthsN=256 monthsN=17B Mode:Median (interquartile range)8 (3.5-12)8 (3-12.5)6 (4-11)5 (2-11)p 0,16Doppler Mode: Median (interquartile range)2 (0.5-6)2 (0-6)2 (0-6)0 (0-2)p 0,005Conclusion:In this cohort half of the patients that responded to treatment had achieved this by month 1. A higher baseline inflammatory profile was related to the response. Little difference is found between month 1 and 6 on clinical data, however ultrasonographic results suggest that at least 6 months are needed for Doppler improvement. Perhaps MTX has a faster effect over joint pain and lowers DAS28 scores requiring longer to completely suppress inflammatory activity.References:[1]Braun, J. et al.

Abstract
Background:Sjogren’s syndrome (SS) is characterized by lymphocytic infiltration of the exocrine glands and marked B-lymphocytic cell hyperreactivity involving a variety of serum autoantibodies.1Salivary Gland Ultrasound (SGU) is a simple, fast, and well- tolerated examination, wich provides information about glandular structure and has proven to be very useful in the Sjögren Syndrome diagnosis2. A prognostic value has also been proposed due to its posible relationship with lymphomas and extra-glandular manifestations.Objectives:The objective of our study is to evaluate ultrasound results in patients who went through an SGU in clinical practice, its usefulness in the diagnosis of Sjögren’s syndrome and the presence of complications (lymphomas, extra-glandular manifestations or factors related to increased lymphoma risk).Methods:We conducted a retrospective cross-sectional study with review of clinical records that included all those patients coded as SGU in the Ultrasound unit of Rheumatology Department from 2016 to December 2019. Information collected included final diagnosis, laboratory results, clinical manifestations and ultrasound results. We performed an analysis on the frequency of pathological SGU and on the relationship between this lesions in patients with final SS diagnosis and the presence of lymphoma, extra-glandular manifestations and the laboratory values related with increased lymphoma risk (low complement levels, cryoglobulinemia, positive autoimmunity).Results:SGU was performed in 171 patients in four years, 162 women (94.7%). The previous diagnoses, reason for the request and final diagnosis are shown in Table 1. The vast majority of the SGU were normal, only 28 (16,3%) were pathological, 13 with a grade II and 8 with a grade III. In the other 7 patients grading was not available. Of the 28 patients with pathological SGU, none had lymphoma, only 3 had recurrent parotitis and 15 had had extra-glandular manifestations, mainly arthralgia / arthritis (12). Only 1 patient, with rheumatoid arthritis, had had a lymphoma and the SGU was normal. Antibody positivity was frequent in pathological SGU, 16/23 antinuclear antibodies, 13/22 anti-Ro and 9/23 rheumatoid factor. Of the 86 patients without previous diagnosis, 18 were diagnosed with Sjogren syndrome, 9 with pathological SGU and the rest were normal. No patient diagnosed with a dry non-autoimmune syndrome presented pathological SGU.Table 1.Previous diagnoses, reason for request and final diagnoses.Previous diagnoses (n: 171)Reason for request (n: 171)Final diagnosis (n: 78)Without prior diagnosis (n: 86)Dry non- autoinmune syndrome (n: 127)Dry non-autoimmune syndrome (n: 60)Primary Sjögren’s syndrome (n: 11)Primary Sjögren’s syndrome (n: 12)Primary Sjögren’s syndrome (n: 18)Systemic Lupus Erythematosus (n: 9)Lymphoma (n: 0)Secondary Sjögren’s syndrome (n: 0)Rheumatoid arthritis (n: 24)Control (n: 13)Other diagnoses (n: 7)Other diagnoses (n: 18)Other reasons (n: 11)Conclusion:The impact of the SGU is low and its use cannot, for now, displace other methods (e.g. salivary gland biopsy) in the diagnosis of SS. Also our low number of patients with pathological SGU together with the low prevalence of the complications studied (e.g. lymphomas = 1) prevents the expected comparisons.References:[1]Ramos-Casals M, Solans R, Rosas J, et al.

Abstract
Background:Musculoskeletal ultrasound (MSUS) is a useful tool to assess disease activity in rheumatoid arthritis (RA) patients. However, it has not yet been established if its use would change treatment decisions within a treat to target strategy or whether it would lead to better outcomes in RA patientsObjectives:Our aim was to determine the impact of MSUS in the clinical management of RA patients and investigate factors associated with subsequent clinical actions by the referring rheumatologistMethods:A prospective analysis of RA patients seen at an MSUS clinic over a 6-month period was undertaken. Pre- and post-US follow-up data (± 3 months) were analyzed. Baseline assessment included clinical features, physical examination and laboratory tests. All MSUS examinations were performed according to EULAR guidelines and using an Esaote MyLab 8 (Esaote, Genoa) with a high frequency (8-15 MHz) transducer. Patients were stratified in groups based on the clinical impact of the MSUS visit: 1) No clinical impact and 2) US findings leading to subsequent clinical action by the referring rheumatologist (including changes in dosages of current rheumatologic treatments, addition/substraction of medications or interventional procedures based on the MSUS results). First, differences between groups were tested using chi-squared and Student-t tests in the univariate analysis. Second, multivariate logistic regression models were employed to investigate factors associated to a change in clinical managementResults:A total of 61 RA patients were included for analysis. Mean age was 61.9± 11.4 years and 51 (83.6%) were female. Disease activity assessment was the most frequent referral reason (43; 70.5%). Overall, MSUS led to a subsequent therapeutic action by the referring rheumatologist in 39 (63.9%) patients, and to a change in the underlying diagnosis and/or in the clinical impression of the chief complaint that generated the referral in 7 (11.5%) patients. Baseline characteristics between both groups are compared in Table 1. In the univariate analysis, the detection of Power Doppler (PD) synovitis/tenosynovitis and 28 swollen joint count were significantly associated with a subsequent clinical action. In the multivariate analysis only PD synovitis/tenosynovitis (OR=3.28; 95%CI 1.06-10.27) remained significantly associated with a change in clinical management (Table 2)Table 1.Baseline characteristics of RA patientsTotal n= 61Change in clinical management n= 39 (63.9%)No change in clinical management n= 22 (36.1%)pAge61.9±11.461.5±12.562.6±9.20.7SexFemale51(83.6%)35(89.7%)16(72.7%)0.09SmokingNon smoker33(54.1%)17(43.6%)16(72.7%)0.08Smoker13(21.3%)11(28.2%)2(9.1%)Former smoker15(24.6%)11(28.2%)13(21.3%)Radiographic erosions29(48.3%)22(57.9%)7(31.8%)0.0528 Tender Joint Count2.3±3.42.7±3.91.6±2.40.228 Swollen Joint Count2±32.6±3.51.1±1.6<0.05ESR (mm/h)28.1±20.626.1±15.531.7±27.40.4CRP (g/L)1±1.51±1.40.9±1.70.7RF (IU/mL)175.8±452.8139.9±249.5243.9±697.40.4ACPA (IU/mL)775.6±998.6619.4±797.11079.9±1,275.90.2US PD synovitis/tenosynovitis37(60.7%)28(71.8%)9(40.9%)<0.05Table 2.Independent factors associated with a change in clinical management based on logistic regression modelpOdds ratio95% C.I.LowerUpper28 Tender Joint Count0.131.240.941.64US PD synovitis/tenosynovitis0.043.281.0610.17Conclusion:The most common indication of MSUS examination in RA patients was disease activity assessment.

Abstract
SummaryWe studied the characteristics of religious practice in a cohort of 67 first admission schizophrenic patients over 5 years. Thirty percent of these patients were involved in religious activities, either with an established religion or in a marginal group. They were mostly women, who had a good premorbid psychosocial adaptation and tended not to be substance abusers. Their social adaptation was improved at year 5. They were as compliant with their ambulatory treatment as the other patients. However, when controlling for the inclusion characteristics, a similar outcome was shown between the group of practicing patients and the nonpracticing group. Religious activity may not be by itself the cause of this favorable outcome, as it is probable that only the patients who are less symptomatic and relatively well adapted could actually join a religious movement. The fact that many schizophrenic patients find an occupation and relationships in religious activities that they would not find elsewhere should encourage the psychiatric community target its occupational goals.

Abstract
Two-dimensional melting is one of the most fascinating and poorly understood phase transitions in nature. Theoretical investigations often point to a two-step melting scenario involving unbinding of topological defects at two distinct temperatures. Here, we report on a novel melting transition of a charge-ordered K-Sn alloy monolayer on a silicon substrate. Melting starts with short-range positional fluctuations in the K sublattice while maintaining long-range order, followed by longer-range K diffusion over small domains, and ultimately resulting in a molten sublattice. Concomitantly, the charge order of the Sn host lattice collapses in a multistep process with both displacive and order-disorder transition characteristics. Our combined experimental and theoretical analysis provides a rare insight into the atomistic processes of a multistep melting transition of a two-dimensional materials system.

Abstract
We exposed juvenile intertidal fish to different amounts of Poly(styrene-co-divinylbenzene) microplastics in their diet. We fed ten individuals with pellets containing 0.01 g, another ten fish with pellets containing 0.1 g of PS, and ten fish without plastic as control. After 45 days of treatment, the whole intestine was removed, and the histological evaluation started immediately. We evaluated inflammation due to leukocyte infiltration (Lk), circulatory disorders like Hypermeia (Hyp), and regressive changes in the intestinal tissue, assessing Crypt cell loss (Ccl) and Villi cell loss (Vcl). The severity of the lesions increased according to the microplastic concentration. In the fish group feeding on microplastics, we found that leukocyte infiltration and hyperemia were more severe in the higher exposure group compared to the lower exposure; and crypt cell loss and villi cell loss increased significantly due to Poly(styrene-co-divinylbenzene) microplastic physical abrasion.

Abstract
Abstract
A liquid chromatographic (LC) method using UV detection at 233 nm was used to study the degradation of methomyl in tomatoes and green beans grown in greenhouses. A liquid-liquid extraction with CH2CI2-methanol (90 + 10, v/v) and a cleanup step with Florisil were combined with LC to isolate, recover, and quantitate the pesticide. Average recoveries obtained at spike levels of 0.03 and 0.40 mg/kg were 83.2-84.7% for tomatoes and 83.387.5% for green beans. Determination limits were 0.03 mg/kg for tomatoes and 0.01 mg/kg for green beans. Levels of methomyl residues were studied in tomatoes and green beans grown in an experimental greenhouse to establish the effect of the kind of greenhouse, application dose, species grown, and climatic conditions on the degradation of this pesticide. Analysis of variance showed that doses did not affect the response. The half-life, however, is greater in a flat-roof greenhouse than in an asymmetric-roof greenhouse and is significantly longer for green beans than for tomatoes and longer in winter than in spring. A preharvest time of about 5 days may be suitable for green beans sprayed with methomyl. Tomatoes show residue levels at the time of application lower than Spanish minimum residue levels.

Abstract
The early detection of bronchial inflammation in asthma, through a non-invasive, simple method and under a subclinical state, could lead to a more effective control of this condition. The aim of this study was to identify biomarkers of bronchial inflammation in the saliva of children with asthma through immunoassay and Surface Enhanced Raman Spectroscopy (SERS). We conducted an analytical cross-sectional study in 44 children ages 6-12; the diagnosis of asthma was made according to Global Initiative for Asthma (GINA) standards. The children's saliva was analyzed by immunoassay for the quantification of 37 cytokines, as well as SERS analysis in a confocal Raman microscope at 785 nm. We found a significant association between bronchial obstruction and IL-8 (p = 0.004), IL-10 (p = 0.008) and sCD163 (p = 0.003). The Raman spectra showed significant amplification in the region of 760 to 1750 cm-1. The Principal Component Analysis and Linear Discriminant Analysis (PCA-LDA) method has a sensitivity of 85%, specificity of 82% and an accuracy of 84% for the diagnosis of asthma. These results demonstrate the presence of a subclinical inflammatory state, suggestive of bronchial remodeling in the population studied. The SERS method is a potential tool for identifying bronchial inflammation and its endotype, allowing for a highly sensitive and specific diagnosis.

Abstract
Sub-Saharan urban centers have to tackle high population growth, lack of sanitation infrastructures and the need for good quality water resources. To characterize the impacts of anthropization on the water resources of the capital of Cameroon (Yaoundé), a multi-disciplinary approach was used in ten sub-watersheds (peri-urban and urban) of the Méfou watershed. Pharmaceutical residues were used as tracers of surface and groundwater contamination caused by the release of domestic wastewater from pit latrines and landfills. A water use survey was conducted in the vicinity of the sampling sites to better assess water use, treatment and management. Available land use and hydro-geomorphological data completed characterization of the sub-watersheds. The combined data showed that natural features (elevation, slope, and hydrography) and human activities (land use) favor rainfall-runoff events and hence surface water contamination. Pharmaceutical monitoring revealed contamination of both surface and groundwater especially in the urban sub-watersheds. Analgesics/anti-inflammatory drugs and anti-epileptic carbamazepine were the most frequently found compounds (in up to 91% of water samples) with concentrations of acetaminophen reaching 5660 ng/L. In urban sub-watersheds, 50% of the groundwater sites used for drinking water were contaminated by diclofenac (476-518 ng/L), carbamazepine (263-335 ng/L), ibuprofen (141-276 ng/L), sulfamethoxazole (<2-1285 ng/L) and acetaminophen (110-111 ng/L), emphasizing the need for a deeper understanding of the interactions between surface and groundwater. The use of groundwater as drinking water by 68% of the total population surveyed raises concerns about population exposure and potential health risks. This case study highlights the need for strategies to limit contamination of the water resource given the predicted future expansion of Sub-Saharan urban centers.

Abstract
Flexible endoscopy has evolved to the point that it includes many endoluminal procedures that once required open or laparoscopic surgery, for instance, antireflux surgery, pyloromyotomy, mucosal and submucosal tumor resections, and even full-thickness resection. However, these procedures remain technically demanding due to flexible technology issues: difficult imaging, limited energy devices, lack of staplers, unsatisfactory suturing abilities, and so on. Transgastric laparoscopy or hybrid laparoscopy/flex endoscopy has been described for almost two decades as an alternative to a pure endoluminal approach, mainly for pancreatic pseudocyst drainage and full-thickness and mucosal resection of various lesions. The approach has never been widely adopted mostly due to cumbersome and difficult to maintain methods of gastric access. We propose to expand the indications of transgastric laparoscopy by using novel endoscopically placed ports to replicate endoscopic procedures particularly in the difficult to access proximal stomach such as endoluminal antireflux surgery. Under general anesthesia, five female pigs (mean weight: 27.6 kg) had endoscopic placement of 3, 5 mm intragastric ports (Endo-TAGSS, Leakwood KS, USA) using a technique similar to percutaneous endoscopic gastrostomy. A 5-mm laparoscope was used for visualization. Laparoendoscopic-assisted plication of the gastroesophageal junction (GEJ) was performed using 3-0 interrupted sutures (Polysorb®, Covidien, Mansfield, MA, USA). A functional lumen imagine probe (EndoFLIP®, Crospon, Inc., Galway, Ireland) was used to measure diameter, cross sectional area (CSA), distensibility, and compliance of GEJ before and after intervention. Once the TAGSS ports were removed, the gastrotomies were closed by using endoscopic over-the-scope clips. At the end of the procedure, animals were euthanized. Five laparoendoscopic-assisted endoluminal plications were performed. The mean operative time was 65.6 min (Endoscopic evaluation: 3.2 min, TAGSS Insertion: 11 min, EndoFLIP evaluation + GEJ Plication: 43.25 min, gastric wall closure: 15 minutes). In all cases, this technique was effective and allowed to achieve an adequate GEJ plication by endoscopic grading and EndoFLIP measurements. Median pre-plication GEJ diameter (D) and median pre-plication GEJ cross-sectional area (CSA) were 11.42 mm (8.6-13.6 mm) and 104.8 mm2 (58-146 mm2). After the procedure, these values were decreased to 6.14 mm (5.7-6.6 mm) and 29.8 mm2 (25-34 mm2) respectively (p = 0.0079). Median pre-plication distensibility (d) and compliance (C) were 7.87 mm2/mmHg (2.4-22.69 mm2/mmHg) and 190.56 mm3/mmHg (70.9-502.8 mm3/mmHg). After the procedure, these values decreased to 1.5 mm2/mmHg (0.7-2.2 mm2/mmHg) and 52.17 mm3/mmHg (21.9-98.7 mm3/mmHg) respectively (p = 0.0317). No intraoperative events were observed. Endoscopically, all valves were felt to be transitioned from a Hill grade 3 (normal state for the animal model) to a Hill grade 1 at the procedure completion. A hybrid laparoendoscopic approach is a feasible alternative for performing intragastric procedures with the assistance of conventional laparoscopic instruments; especially in cases where the intervention location limits the access to standard endoscopy or where endoscopic technology is inadequate. Further evaluation is planned in survival models and clinical trials.

Abstract
Treatment of human immunodeficiency virus(HIV) in cancer patients improves outcomes and reduces transmission of this oncogenic virus. HIV testing rates of cancer patients are similar to the general population (15-40%), despite the association with cancer. Our aim was to increase HIV screening in the Emergency Department(ED) of a comprehensive cancer center through a quality initiative. Testing increased significantly during the intervention (p<0.001; 0.15/day to 2.69/day). Seropositive HIV rate was 1.4% (12/852), with incidence of 0.3%. All patients were linked to care. Incident cases were between 36 and 55 years of age. Barriers encountered included confusion regarding the need for written consent for HIV testing, failure to consider ordering the test, and concerns regarding linkage to care.

Abstract
Background Chlorhexidine is an irrigant solution widely used in root canal treatment because of its good antimicrobial properties. However, its mixture with sodium hypochlorite results in the appearance of substance called p-chloroaniline, a cytotoxic substance. This is also found when chlorhexidine is heated. The use of passive ultrasonic irrigation is related to an irrigant thermal increase, which can cause the appearance of p-chloroaniline. Thus, the objective is to establish the influence of ultrasonic and sonic activation, with the use of different intensities, upon the temperature of chlorhexidine gluconate (CHX). Material and Methods The following groups were established: control (without activation), ultrasonic activation and sonic activation. A 0.5-ml volume of CHX was placed in an Eppendorf tube in a thermo-static bath at 37ºC. Both methods resulted in immediate CHX activation. The temperature was recorded every 30 seconds between 60 and 180 seconds. The statistical analysis was performed based on the Mann-Whitney U-test. Results Both groups subjected to activation showed higher temperatures than the control group, and increased activation intensity was associated to greater temperature increments in both activated groups. Conclusions Both ultrasonic and sonic activation are correlated to temperature increase in CHX. Key words:Chlorhexidine, p-choroaniline, PUI, sonic irrigation, temperature.
