Abstract
Introduction After COVID-19, functional and tomographic lung alterations may occur, but there are no studies at high altitude where, due to lower barometric pressure, there are lower levels of arterial oxygen pressure and saturation in both normal subjects and patients with respiratory disease. In this study, we evaluated the computed tomographic (CT), clinical, and functional involvement at 3 and 6 months post-hospitalization in survivors with moderate-severe COVID-19, as well the risk factors associated with abnormal lung computed tomography (ALCT) at 6 months of follow-up. Materials and methods Prospective cohort, after hospitalization for COVID-19, of patients older than 18 years residing at high altitude. Follow-up at 3 and 6 months with lung CT, spirometry, diffusing capacity of the lung for carbon monoxide (DLCO), six-minute walk test (6MWT), and oxygen saturation (SpO2). Comparisons between ALCT and normal lung computed tomography (NLCT) groups with X2 and Mann-Whitney U test, and paired test for changes between 3 and 6 months. A multivariate analysis was performed to evaluate the variables associated with ALCT at 6-month follow-up. Results We included 158 patients, 22.2% hospitalized in intensive care unit (ICU), 92.4% with typical COVID CT scan (peripheral, bilateral, or multifocal ground glass, with or without consolidation or findings of organizing pneumonia), and median hospitalization of 7 days. At 6 months, 53 patients (33.5%) had ALCT. There were no differences between ALCT and NLCT groups in symptoms or comorbidities on admission. ALCT patients were older and more frequently men, smokers and hospitalized in ICU. At 3 months, ALCT patients had more frequently a reduced forced vital capacity (< 80%), and lower meters walked (6MWT) and SpO2. At 6 months, all patients improved lung function with no differences between groups, but there were more dyspnea and lower exercise SpO2 in ALCT group. The variables associated with ALCT at 6 months were age, sex, ICU stay, and typical CT scan. Conclusion At 6-month follow-up, 33.5% of patients with moderate and severe COVID had ALCT. These patients had more dyspnea and lower SpO2 in exercise. Regardless of the persistence of tomographic abnormalities, lung function and 6MWT improved. We identified the variables associated with ALCT.

Abstract
Abstract
Background
Anastomotic leak (AL) is a common but severe complication after oesophagectomy. It is unknown how to determine the severity of AL objectively at diagnosis. Determining leak severity may guide treatment decisions and improve future research. This study aimed to identify leak-related prognostic factors for mortality, and to develop a Severity of oEsophageal Anastomotic Leak (SEAL) score.
Methods
This international, retrospective cohort study in 71 centres worldwide included patients with AL after oesophagectomy between 2011 and 2019. The primary endpoint was 90-day mortality. Leak-related prognostic factors were identified after adjusting for confounders and were included in multivariable logistic regression to develop the SEAL score. Four classes of leak severity (mild, moderate, severe, and critical) were defined based on the risk of 90-day mortality, and the score was validated internally.
Results
Some 1509 patients with AL were included and the 90-day mortality rate was 11.7 per cent. Twelve leak-related prognostic factors were included in the SEAL score. The score showed good calibration and discrimination (c-index 0.77, 95 per cent c.i. 0.73 to 0.81). Higher classes of leak severity graded by the SEAL score were associated with a significant increase in duration of ICU stay, healing time, Comprehensive Complication Index score, and Esophagectomy Complications Consensus Group classification.
Conclusion
The SEAL score grades leak severity into four classes by combining 12 leak-related predictors and can be used to the assess severity of AL after oesophagectomy.

Abstract
BackgroundIt has been postulated that AGES could have a relevant role as inducers in the chronic inflammatory pathway present in various diseases1; among them, in immune-mediated diseases such as SLE, as well as that its concentration could be related to some parameters of the disease such as activity 2 or accumulated damage 3, showing studies discrepant results to date.ObjectivesTo describe correlations between the concentrations of AGEs measured by cutaneous autofluorescence and various parameters related to the disease in a population of SLE patients.MethodsAGE concentrations were measured by skin autofluorescence (Age Reader Mu Connect from Diagnoptics Technologies BV) in 66 SLE Caucasian patients and correlations with demographic and clinical data were analyzed, after adjusting for age, smoking and corticosteroids as possible confounding factors, according to previous data. Previous validation studies have shown that skin autofluorescence is strongly related to AGE levels in skin biopsies4. The indices were analyzed both as quantitative and categorized variables according to previously established categories or to medians/tertiles/quartiles depending on the distribution of the variable in our population.ResultsTable 1 shows some descriptive characteristics of our cohort. There were clinically and statistically significant differences in the values of AGEs according to the patient’s SLEDAI and SLICC. Specifically, it was observed that AGEs’ values in the population with severe activity according to SLEDAI was 0.61 (95% CI 0.85-2.046; p=0.045) points > than in those in remission (p=0.045); as well as AGEs‘ values in patients with SLICC ≥1 was 1.23 (95% CI 0.49-1.98; p=0.030) points > than in the group without cumulative damage. In all the models, the values of AGEs increased significantly with age, smoking and current treatment with corticosteroids, except for the model including the SLICC variable. Interactions in said model were explored, and it was observed that the concentration of AGES depended on the interaction between the value of SLICC and the intake of corticosteroids, so that differences were only observed between SLICC groups in those who took corticosteroids.Table 1.Descriptive characteristics of the cohort. c: categorized.AverageSD%Age5415BMI25.364.68SmokerNo68.2Yes31.8AGEs2.60.7Disease duration (years)1611DAS282.221.16cDAS28remission71.2low9.1moderate15.2high4.5SLEDAI54cSLEDAIremission21.2low16.7moderate51.5high10.6SLICC11cSLICC00.0148.5>130.3321.2FACIT Fatigue Scale1810Patient global assessment (PGA)3.02.4cPGA0-131.82-328.8>339.4Physician global assessment1.71.3cPhysician global assessment0-147.0>153.0Visual Analogue Scale (VAS)3.13.1cVAS034.81-430.3>434.8Health Assessment Questionnaire (HAQ)0.5270.551cHAQ033.30-0.7536.4>0.7530.3CorticoidsYes27.3No72.7ConclusionA correlation with elevated values of AGEs was observed in those SLE patients with higher scores in the indexes of activity (SLEDAI) and damage accrual (SLICC). The fact that the differences in SLICC are only observed in those patients treated with corticosteroids suggests that, maybe, only the accumulated damage related to taking corticosteroids could be mediated by AGEs.References[1]Medzhitov R.

Abstract
BackgroundAdvanced glycation endproducts (AGEs) are the result of non-enzymatic glycation of proteins, lipids or nucleic acids. In circumstances characterized by increased oxidative and carbonyl stress, such as chronic inflammation, AGEs can be formed more rapidly1, generating reactive oxygen species and activating inflammatory signaling cascades through their chief signaling receptor (commonly abbreviated as RAGE)2. This positive feedback of inflammation can play a role in the etiology of immune-mediated inflammatory diseases, more specifically in rheumatoid arthritis (RA), ankylosing spondylitis (AS) and systemic lupus erythematosus (SLE).ObjectivesTo investigate whether the accumulated concentrations of AGEs in patients with SLE, RA or AS are significantly higher than in healthy patients.MethodsOne hundred thirteen consecutive patients fulfilling ACR/EULAR criteria for RA, 60 patients fulfilling ASAS/OMERACT MRI criteria for AS, 97 patients fulfilling ACR/SLICC criteria for SLE and 527 sex-matched healthy controls were recruited.in cross-sectional study. Exclusion criteria were pregnancy, diabetes mellitus, corticosteroid treatment ≥ 20mg/day and malignant neoplasm. Accumulated AGEs were non-invasively measured by skin autofluorescence (Age Reader Mu Connect, Diagnostics Technologies B.V) and demographic and clinical data were collected. AGEs comparisons between patients and controls were performed by multiple linear regression analysis adjusted by confunders, previously described in literature (age, smoking habit and cardiovascular risk-factors). Age was centered at 55 years.ResultsTable 1 shows some descriptive characteristics of our cohorts. AGEs adjusted mean was significantly increased in SLE patients compared with matched controls (95% CI [2.27, 2.76] vs [1.66, 1.89], p<0.0001), RA patients and controls (95% CI [2.41, 2.61] vs [1.68, 1.88], p<0.0001) and AS patients and controls (95% CI [2.03, 2.6] vs [1.66, 1.93], p<0.0001). In all 3 models, AGEs were also significantly positive correlated with smoking habit measured by packs per year (p<0.001) and age (p<0.0001).Table 1.Descriptive characteristics of the cohortsSLERAASPatientsControlsPatientsControlsPatientsControlsN=96N=189N=113N=240N=60N=99AGEs2.57 (0.65)1.98 (0.45)2.59 (0.58)2.00 (0.42)2.26 (0.46)1.90 (0.46)Age51.0 [43.0;61.0]56.0 [52.0;62.0]58.0 [54.0;65.0]61.0 [56.0;66.0]47.5 [41.0;55.0]53.0 [49.0;57.0]SmokerNo76 (79.2%)133 (70.4%)86 (76.1%)196 (81.7%)42 (70.0%)58 (58.6%)Yes20 (20.8%)56 (29.6%)27 (23.9%)44 (18.3%)18 (30.0%)41 (41.4%)Packs/year0.00 [0.00;10.8]2.50 [0.00;18.8]2.50 [0.00;18.0]0.00 [0.00;12.6]0.00 [0.00;7.88]14.9 [2.00;30.6]HypertensionNo74 (77.1%)116 (61.4%)77 (68.1%)146 (60.8%)53 (88.3%)75 (75.8%)Yes22 (22.9%)73 (38.6%)36 (31.9%)94 (39.2%)7 (11.7%)24 (24.2%)ObesityNo80 (83.3%)128 (67.7%)86 (76.1%)163 (67.9%)51 (85.0%)81 (81.8%)Yes16 (16.7%)61 (32.3%)27 (23.9%)77 (32.1%)9 (15.0%)18 (18.2%)DyslipidemiaNo85 (88.5%)104 (55.0%)79 (69.9%)108 (45.0%)51 (85.0%)55 (55.6%)Yes11 (11.5%)85 (45.0%)34 (30.1%)132 (55.0%)9 (15.0%)44 (44.4%)Continuous normal: mean (SD); Continuous non-normal: median [IQR]; Categorical: absolute (relative frequency)ConclusionAccumulated AGEs in all 3 pathologies are significantly higher than in the healthy controls.

Abstract
INTRODUCTION Pediatric tracheostomy indications have changed over the last 30 years, from acute and transient pro cedures secondary to airway obstruction to programmed tracheostomies indicated due to the need for chronic use of mechanical ventilation (MV). OBJECTIVE To describe indications and morbidity associated with pediatric tracheostomies during a ten-year period. PATIENTS AND METHODS Descrip tive study. Clinical records review of discharged patients (< 15 years old) tracheostomized during their hospital stay between 2005 and 2015. Demographic and clinical variables were evaluated before and after tracheostomy, stay in intensive care unit, age at the time of the tracheostomy, indication of tracheostomy, early complications (< 7 days), late complications (> 7 days), and mortality. RESULTS 59 children with tracheostomy were analyzed, 36 (59%) tracheostomies were performed in children under 6 months, and 39 (60%) in males. 23 (39%) had a confirmed or under study genopathy and 25 (42%) had congenital heart disease. The main indications for tracheostomy were 58% secondary to airway disease and 42% due to chronic use of MV. Within the airway disease group, subglottic steno sis, vocal cord paralysis, and tracheobronchomalacia were the principal reasons for indication, and in the group of chronic use of MV, the main causes were bronchopulmonary dysplasia and chronic lung disease. We did not find tracheostomy-related mortality. 89% of the patients were discharged with tracheostomy and 59% with chronic use of MV. The probability of being discharged with a tracheos tomy was higher in younger patients while the chronic use of MV at discharge was higher in patients with a greater number of extubation failures before tracheostomy. CONCLUSION Tracheostomy is a safe procedure in children, where the predominant causes of indication are airway disease and the need for chronic use of MV. Most children with tracheostomies are discharged with tracheostomy and chronic use of MV. Younger children, those with difficult weaning, confirmed or suspected ge nopathy, or special health needs are at greater risk of needing tracheostomy and chronic use of MV.

Abstract
To estimate the frequency of headache in patients with confirmed COVID-19 and characterize the phenotype of headache attributed to COVID-19, comparing patients depending on the need of hospitalization and sex, an observational study was done. We systematically screened all eligible patients from a reference population of 261,431 between March 8 (first case) and April 11, 2020. A physician administered a survey assessing demographic and clinical data and the phenotype of the headache. During the study period, 2194 patients out of the population at risk were diagnosed with COVID-19. Headache was described by 514/2194 patients (23.4%, 95% CI 21.7–25.3%), including 383/1614 (23.7%) outpatients and 131/580 (22.6%) inpatients. The headache phenotype was studied in detail in 458 patients (mean age, 51 years; 72% female; prior history of headache, 49%). Headache was the most frequent first symptom of COVID-19. Median headache onset was within 24 h, median duration was 7 days and persisted after 1 month in 13% of patients. Pain was bilateral (80%), predominantly frontal (71%), with pressing quality (75%), of severe intensity. Systemic symptoms were present in 98% of patients. Headache frequency and phenotype was similar in patients with and without need for hospitalization and when comparing male and female patients, being more intense in females. Trial registration: This study was supported by the Institute of Health Carlos III (ISCIII), code 07.04.467804.74011 and Regional Health Administration, Gerencia Regional de Salud, Castilla y Leon (GRS: 2289/A/2020).

Abstract
Background:Patient adherence is a key determinant of treatment success in rheumatologic immune-mediated diseases. Available data about adherence to biological treatments and factors associated to non-adherence is limited in Spain. Moreover, no studies compare adherence between subcutaneous and oral drugs.Objectives:To evaluate non-adherence to prescribed subcutaneous biologicals and oral drugs in patients with rheumatologic immune-mediated diseases and to assess possible predictor factors associated to treatment non-adherence.Methods:Retrospective observational study including all patients with oral and subcutaneous treatment for rheumatologic immune-mediated diseases from 2017 to 2019 in the outpatient pharmaceutical care area from a tertiary university hospital. Non-adherence was evaluated by reviewing all scheduled drug-dispensing visits in the computerized application. We considered non-adherent every time that a patient missed at least one drug administration.Data collected: demographic, total patients and patient-treatments, total dispensing visits and route of administration for drug dispensed in every visit.We classified patients in adherent and non-adherent considering dispensing visits. Non-adherent group: number of dispensing visits, reasons for non-adherence, number of missed administrations per patient and drug and predictor factors for non-adherence.Results:783 patients included: 52.4(13.7) years; 427(54.5%) female; 164 (20.9%) smoker; 697 (89%) Caucasian.A total of 79 (10.1%) of 783 patients received more than one treatment.869 patient-treatments: 294 adalimumab (33.8%), 236 etanercept (27.2%), 78 golimumab (8.9%), 47 apremilast (5.4%), 39 certolizumab (4.5%), 34 secukinumab (3.9%), 30 tocilizumab (3.5%).9,197 dispensing visits. Route of administration: 6,406 subcutaneous (93.2%), 374 oral (6.8%).Non-adherence analysis: 2417 (26.3%) dispensing visits, reasons for non-adherence/ dispensing visits: 92 unjustified (97.5%), 33 infection (1.4%), 18 (surgery) 0.7%, 3 pregnancy (0.1%), 6 others (0.3%).Number of missed administrations/patient treatment: 675 patients missed at least one administration (77.7%).Mean 2.5 (±12.9) missed administrations.Number of missed administrations/drug: 9.9 baricitinib (±20.8), 15.8 tofacitinib (±31.2), 25.4 apremilast (±53.2).Predictor factors for non-adherence: ethnicity (p=0.015), treatment with golimumab (p=0.006), and tocilizumab (p=0.036). Age (p=0.072).Conclusion:- Non-adherence to the prescribed drug occurred in 77.7% of patients with rheumatologic immune-mediated diseases- Demographic factors such as ethnicity as well as golimumab and tocilizumab treatment, despite their different frequency of administration, were predictors for non-adherence- Route of administration did not influence non-adherence.Disclosure of Interests:None declared

Abstract
BACKGROUND/OBJECTIVES Immune-mediated inflammatory diseases (IMIDs) are prevalent diseases. There is, however, a lack of understanding of the link between diet and IMIDs, how much dietary patterns vary between them and if there are food groups associated with a worsening of the disease. SUBJECTS/METHODS To answer these questions we analyzed a nation-wide cohort of n = 11,308 patients from six prevalent IMIDs and 2050 healthy controls. We compared their weekly intake of the major food categories, and used a Mendelian randomization approach to determine which dietary changes are caused by disease. Within each IMID, we analyzed the association between food frequency and disease severity. RESULTS After quality control, n = 11,230 recruited individuals were used in this study. We found that diet is profoundly altered in all IMIDs: at least three food categories are significantly altered in each disease (P < 0.05). Inflammatory bowel diseases showed the largest differences compared to controls (n ≥ 8 categories, P < 0.05). Mendelian randomization analysis supported that some of these dietary changes, like vegetable reduction in Crohn's Disease (P = 2.5 × 10-10, OR(95% CI) = 0.73(0.65, 0.80)), are caused by the disease. Except for Psoriatic Arthritis and Systemic Lupus Erythematosus, we have found ≥2 food groups significantly associated with disease severity in the other IMIDs (P < 0.05). CONCLUSIONS This cross-disease study demonstrates that prevalent IMIDs are associated to a significant change in the normal dietary patterns. This variation is highly disease-specific and, in some cases, it is caused by the disease itself. Severity in IMIDs is also associated with specific food groups. The results of this study underscore the importance of studying diet in IMIDs.

Abstract
BACKGROUND Cumulative burden of multiple mental health conditions may worsen physical health outcomes in vulnerable populations. Accordingly, identifying cumulative burdens of mental health conditions that may affect HIV treatment and care can guide public health strategies to reduce their impact on HIV-related health outcomes. This study examined the relationship between the cumulative burden of mental health conditions and factors associated with engagement in HIV care in Argentina. METHOD Data for this study was obtained at baseline from Conexiones y Opciones Positivas en la Argentina 2 (COPA2). Participants (N = 360) were cisgender patients living with HIV who were lost to care, recruited from seven clinics serving people living with HIV in four Argentine urban centers. Cumulative burden of mental health conditions (i.e., depressive symptoms, problematic substance use, unhealthy alcohol use, and psychotic symptoms) was assessed. RESULTS Every one-point increase in the number of mental health conditions present was associated with a decrement in patient-provider communication (b = - 0.22, p < .001), self-efficacy (b = - 0.13, p = .012), and motivation for adherence (b = - 0.11, p = .039). CONCLUSION This study found cumulative burden of depression, problematic substance use, unhealthy alcohol use, and psychotic symptoms to be negatively associated with factors related to engagement in HIV care. Results highlight the importance of identification and treatment of challenges to mental health, in order to ameliorate their influence on engagement in HIV care.

Abstract
Background:Systemic inflammatory diseases are common in women at the reproductive age. These women may have fertility problems and complications during pregnancy.Objectives:To describe the experience in a multidisciplinary unit (composed of Rheumatologists and Obstetricians) and asses the complications and treatments used in patients with inflammatory diseases in a tertiary hospital compared to those registered in healthy women from the same center (preterm births 6.59%, Caesarean section (C-section) 14.4%, maternal average age 33.33 years).Methods:Retrospective and descriptive study of the evolution of pregnancy in patients with inflammatory diseases and follow-up in a multidisciplinary unit for more than 15 years (until December 2019). Demographics, maternal disease, time until conception, births, abortions, C-sections, treatments and complications were collected. Data was analyzed using IBM SPSS v23.Results:We registered 29 pregnancies (25 patients): 20 Rheumatoid Arthritis (RA), 5 Psoriatic Arthritis (PsA), and 4 Spondylarthritis (SpA). Maternal average age at diagnosis was 27.6±6.36 years and average age at childbirth/abortion 35±5.6 years.It took an average time of 8 months to conceive. 11.5% received fertility treatment using in vitro fertilization techniques.5 abortions were registered prior to follow-up in this unit (0.2 abortions/mother). During follow-up 1 abortion (0.04 abortions/mother) was recorded in a RA patient. C-section was performed in 11 cases (39.2%): 6 RA (31.6%), 3 SpA (75%) and 2 PsA (40%).17.2% of pregnancies were preterm (<37 weeks).Intrauterine growth restriction (IUGR) was observed in a woman (3.4%) with RA and preeclampsia was observed in 2 cases (6.9%) (RA 1, SpA 1).Disease activity (DAS28 and BASDAI) is shown in Table 1.Table 1.DAS28 (median)PreviousFirstTrimesterSecondTrimesterThirdTrimesterPosteriorRheumatoid Arthritis2.692.593.093.333.11Psoriatic Arthritis2.582.53.323.082.89RA with biological agents (n: 6)2.372.942.712.42.52BASDAI (median)Spondylarthritis2.82.41.7511.9Treatments used prior to and during pregnancy are listed in Table 2.Table 2.TREATMENT BEFORE PREGNANCYn (%)TREATMENT DURINGPREGNANCYn (%)Hydroxychloroquine13 (44.8%)Prednisone17 (58.6%)Prednisone12 (41.4%)Acetylsalicylic acid16 (55.2%)Methotrexate9 (31%)Hydroxychloroquine15 (51.7%)TNF inhibitors7 (24.1%)Sulfasalazine2 (6.9%)Sulfasalazine2 (6.9%)TNF inhibitors2 (6.9%)8 patients had received biological treatment prior to pregnancy (2 SpA, 6 RA)(3 Etanercept, 3 Adalimumab, 2 Certolizumab). 2 of them (RA) continued treatment during pregnancy. 1 of them discontinued it at week 17 on her own (Adalimumab) while the other continued with Certolizumab throughout pregnancy and presented IUGR. No other complications, such as infections or malformation, were observed in newborns. DAS28 data of these women can be found in Table 1.Conclusion:In our series, as described in the literature, women with inflammatory arthropaties are older, need longer time to achieve pregnancy and have increased use of fertility techniques and increased likelihood of preterm and instrumental delivery compared to general population. Given the low number of patients receiving biological treatment no conclusions about complications and evolution of the disease can be drawn, so further investigation are needed in this group of patients.Monitoring inflammatory arthropathies in a multidisciplinary unit increases the chances of successful pregnancies.Disclosure of Interests:None declared

Abstract
The COVID-19 pandemic caused a change in our society and put health systems in crisis worldwide. Different risk factors and comorbidities have been found that increase the risk of mortality when acquiring this infection. The use of alternative devices to the cigarette like the electronic cigarettes, the vapers have been studied widely and generators of great controversy since it has been discovered that they also produce different pulmonary affections. When developing the SARS-CoV2 infection, different theories have been generated about the greater predisposition to a worse prognosis of people who use electronic cigarettes; however, the information on this continues in discovery. A group of experts made up of oncologists, infectologists, pulmonologists, and epidemiologists met to review the literature and then generate theories about the impact of electronic cigarettes on SARS-CoV2 infection.

Abstract
This study explores the effect of 229Th tracer tail interference on the determination of the sensitivity of 230Th alpha spectrometry of samples with environmental levels of radioactivity. Tracer peak tail interference was calculated with Suma-Alpha, whilst Visual Basic for Applications (VBA in Excel©) software was used to study the variation in sensitivity in terms of the amount of tracer added. Unnecessary increases in the amount of tracer or extended sample measuring times were observed to have adverse effects on method sensitivity (Detection Limit- Ld).

Abstract
The shift from rainfed to irrigated agriculture is associated with a change in the fertilization rates due to increases in expected production and the fact of growing more N demanding crops. In addition, the circulation of irrigation return flows (IRF) mobilizes soluble salts stored in soils or geological materials. As a consequence, it implies severe modifications in the dynamics and total amount of soluble salts and nitrogen exported, especially in semi-arid watersheds. In this study, long-term data collected by the regional authorities was used to assess the effects of irrigation implementation on salinity (using electrical conductivity, EC, as a proxy) and nitrate concentration (NO3-) after the transformation of ca. 77 km2 from rainfed to irrigated agriculture in the Cidacos River (CR) watershed. The results indicate that water quality in the lower reaches of the CR was significantly modified after the diffuse incorporation of IRF. In contrast, neither EC nor NO3- were different in those monitoring stations whose contributing watersheds did not include transformed area. In addition, the temporal dynamics in the analysed variables shifted from a rainfed land signal typical in the region to an irrigated land signal, and the hydrochemical type of the CR shifted from mixed-to-Na+-mixed-to-HCO3- to mostly Na+-mixed type, typical of waters affected by IRF in the region. Groundwater EC and NO3- also increased in those wells located within the irrigated area. Although there are great uncertainties in the actual amount of salt and N reaching the CR via IRF, the expected contribution of waste water spilled into the CR is minor in comparison to other sources, mostly agricultural sources in the case of N. The observed changes have promoted the designation of the lower reaches of the CR as "affected" by NO3- pollution, and the whole CR watershed as a Nitrate Vulnerable Zone, with the emergent question about whether irrigation implementation as carried out currently in Spain is against the environmental objectives of the Water Framework Directive.

Abstract
BACKGROUND Environmental surfaces are a potential vehicle for the transmission of norovirus outbreaks in closed and semi-closed settings. Testing of environmental samples may help control outbreaks. AIM To assess the level of environmental contamination by norovirus in acute gastroenteritis outbreaks in closed or semi-closed settings (nursing homes, schools, kindergartens, youth accommodations, hospitals and social health centres) in the Barcelona region between January 2017 and March 2019. METHODS A prospective surveillance study was carried out. Environmental samples (529) were collected in 46 of the 50 outbreaks of acute norovirus gastroenteritis from environmental surfaces of common areas, bathrooms and kitchens in closed and semi-closed settings when the outbreak was notified and 10 days later. Instructions for taking environmental samples were distributed to public health inspectors. Norovirus was detected by reverse transcription polymerase chain reaction. FINDINGS Environmental samples were positive for norovirus in 31 (67.4%) outbreaks. Norovirus was most frequently detected on elevator buttons (4/17, 24%), toilet handles (16/66, 24%) and handrail bars (7/34, 21%). Positive samples from the first sampling were mainly found in bathrooms and greater viral persistence in the second sampling was found on elevator buttons and TV remote controls. Nursing homes were the setting with the most types of environmental surfaces contaminated (82% in first samples and 55% in second samples). CONCLUSION The probability of virus detection is independent of the time between notification of the outbreak or symptom onset and sample collection. Our results suggest possible defects in cleaning protocols and disinfection in closed and semi-closed settings.

Abstract
OBJECTIVE We aimed to investigate the impact of the toxicological results found in cases of sudden death (SD) and to correlate the clinical, autopsy and genetic findings with the toxicology results. MATERIALS AND METHODS Consecutive SD in people aged between 16 and 50 years with medico-legal autopsies and toxicology studies were included over a 3-year period. The comparison between the toxicological data and demographic characteristics, clinical circumstances, autopsy, and genetic results were taken into account. RESULTS 101 cases were finally included. They were predominately males (84%) and the mean age was 39.8 years. 52 (51.5%) cases had positive toxicological findings and in 25 cases (24.8%), toxic compounds were considered the first cause of death. Ethanol was the most frequently identified agent (69%), following by licit drugs (56%) and drugs of abuse (39%). Cases with positive toxicology were younger than those with negative results (37.9±9.1 vs. 41.9±7.8; p=0.02). Patients with more than 3 comorbidities showed an association with positive toxicological results (n=14 vs. n=3; p=0.017). The genetic study was performed in 70 (69.3%) SD cases. We identified pathogenic or likely pathogenic variants in 17.1% cases and uncertain significance variants in 42.8% cases. 58% of these variants were probably related to the cause of death. CONCLUSIONS A large fraction of SD victims had positive toxicological findings and a quarter of deaths were directly caused by toxic substances. The identification of the factors that trigger SD provides a good approach to contribute in avoiding future episodes.

Abstract
Meningoencephalitis of unknown origin (MUO) is a common inflammatory disease of the central nervous system. Several studies investigated finding prognostic factors, but results are contradictory. The aim of this study was to determine the concentrations of blood lactate (Blood-L) and cerebrospinal fluid lactate (CSF-L) in dogs with MUO for prognostic purposes. A total of 45 dogs with MUO (MUO group) and 11 with idiopathic epilepsy (IE group) were included. In the MUO group, 22 dogs were treated with prednisolone + cytosine arabinoside, 17 with prednisolone ± cyclosporine, and six received no treatment. In the MUO group, there was a strong-moderate positive correlation between Blood-L and CSF-L (ρ = 0.63557; P < 0.0001), a strong-moderate negative correlation between survival and CSF-L (ρ= -0.50210; P < 0.0004), and a weak negative correlation between survival and Blood-L (ρ= -0.35685; P < 0.0220). Dogs with a favourable response to treatment at 1 month had lower initial concentrations of Blood-L and CSF-L (P < 0.0010; P < 0.0037), and those with a worse response had higher values (P < 0.0497; P < 0.0004). Dogs that remained stable with treatment showed lower CSF-L concentrations (P < 0.0013). Dogs with Blood-L>4 mmol/L (P < 0.03) and/or CSF-L> 4 mmol/L (P < 0.009) had lower survival rates with the latter also showing more severe signs, probably indicating severe neuronal damage. These findings suggest that concentrations of CSF-L and Blood-L in dogs with MUO could be used as prognostic indicators.

Abstract
This study aimed to analyze the spatial and temporal variation of the vegetation in the northern Argentine Puna, utilizing both field sampling and remote-sensing tools. The study was performed within the Pozuelos Biosphere Reserve (Jujuy province, Argentina), which aims to generate socio-economic development compatible with biodiversity conservation. Our study was designed to analyze the dynamics of the Puna vegetation at local scale and assess and monitor the seasonal (dry and wet seasons), interannual, and spatial variation of the vegetation cover, biomass, dominant species, and vegetation indices. Ten vegetation units (with differences in composition, cover, and high and low stratum biomass) were identified at our study site. The diversity of these vegetation units correlated with geomorphology and soil type. In the dry season, the vegetation unit with greatest vegetation cover and biomass was the Festuca chrysophylla grassland, whereas in the wet season, the units with greatest cover and biomass were vegas (peatlands) and short grasslands. The Festuca chrysophylla grasslands and short grasslands were located in areas with clay soils, except peatlands, associated with valleys and coarse-texture soils. The vegetation indices used (NDVI, SAVI, and MSAVI2) were able to differentiate functional types of vegetation and showed a good statistical fit with cover values. Our results suggest that the integrated utilization of remote-sensing tools and field surveys improves the assessment of the Puna vegetation and would allow a periodic monitoring at production unit scale taking into account its spatial and temporal variation.

Abstract
BACKGROUND The malignant mechanisms that control the development of cutaneous T-cell lymphoma (CTCL) are beginning to be identified. Recent evidence suggests that disturbances in specific intracellular signalling pathways, such as RAS-mitogen-activated protein kinase, T-cell receptor (TCR)-phospholipase C gamma 1 (PLCG1)-nuclear factor of activated T cells (NFAT) and Janus kinase (JAK)-signal transducer and activator of transcription (STAT), may play an essential role in the pathogenesis of CTCL. OBJECTIVES To investigate the mechanisms controlling disease development and progression in mycosis fungoides (MF), the most common form of CTCL. METHODS We collected 100 samples that were submitted for diagnosis of, or a second opinion regarding, MF between 2001 and 2018, 80% of which were in the early clinical stages of the disease. Formalin-fixed paraffin-embedded tissues were used for histological review and to measure the expression by immunohistochemistry of surrogate markers of activation of the TCR-PLCG1-NFAT, JAK-STAT and NF-κB pathways. Folliculotropism and large-cell transformation were also examined. RESULTS NFAT and nuclear factor kappa B (NF-κB) markers showed a comparable activation status in early and advanced stages, while STAT3 activation was more frequent in advanced stages and was associated with large-cell transformation. Consistently with this observation, STAT3 activation occurred in parallel with MF progression in two initially MF-negative cases. A significant association of NFAT with NF-κB markers was also found, reflecting a common mechanism of activation in the two pathways. Genomic studies identified nine mutations in seven genes known to play a potential role in tumorigenesis in T-cell leukaemia/lymphoma, including PLCG1, JAK3 and STAT3, which underlies the activation of these key cell-survival pathways. A higher mutational allele frequency was detected in advanced stages. CONCLUSIONS Our results show that STAT3 is activated in advanced cases and is associated with large-cell transformation, while the activation of NFAT and NF-κB is maintained throughout the disease. These findings could have important diagnostic and therapeutic implications. What's already known about this topic? Mycosis fungoides is characterized by a clonal expansion of T cells in the skin. The mechanisms controlling disease development and progression are not fully understood. What does this study add? An association of the nuclear factor of activated T cells and nuclear factor kappa B pathways was found, which could reflect a common mechanism of activation. These pathways were activated in early and advanced stages at the same level. Signal transducer and activator of transcription 3 activation was associated with large-cell transformation and was more frequent in advanced stages. A genomic analysis of cutaneous T-cell lymphoma-associated genes was performed. Nine mutations were detected. What is the translational message? These results could have important implications for the treatment of MF in the near future.

Abstract
Background: Rheumatoid arthritis (RA) is the most frequent autoimmune disease involving the joints. Although anti-TNF therapies have proven effective in the management of RA, approximately one third of patients do not show a significant clinical response. The objective of this study was to identify new genetic variation associated with the clinical response to anti-TNF therapy in RA. Methods: We performed a sequential multi-omic analysis integrating different sources of molecular information. First, we extracted the RNA from synovial biopsies of 11 RA patients starting anti-TNF therapy to identify gene coexpression modules (GCMs) in the RA synovium. Second, we analyzed the transcriptomic association between each GCM and the clinical response to anti-TNF therapy. The clinical response was determined at week 14 using the EULAR criteria. Third, we analyzed the association between the GCMs and anti-TNF response at the genetic level. For this objective, we used genome-wide data from a cohort of 348 anti-TNF treated patients from Spain. The GCMs that were significantly associated with the anti-TNF response were then tested for validation in an independent cohort of 2,706 anti-TNF treated patients. Finally, the functional implication of the validated GCMs was evaluated via pathway and cell type epigenetic enrichment analyses. Results: A total of 149 GCMs were identified in the RA synovium. From these, 13 GCMs were found to be significantly associated with anti-TNF response (P < 0.05). At the genetic level, we detected two of the 13 GCMs to be significantly associated with the response to adalimumab (P = 0.0015) and infliximab (P = 0.021) in the Spain cohort. Using the independent cohort of RA patients, we replicated the association of the GCM associated with the response to adalimumab (P = 0.0019). The validated module was found to be significantly enriched for genes involved in the nucleotide metabolism (P = 2.41e-5) and epigenetic marks from immune cells, including CD4+ regulatory T cells (P = 0.041). Conclusions: These findings show the existence of a drug-specific genetic basis for anti-TNF response, thereby supporting treatment stratification in the search for response biomarkers in RA.

Abstract
BACKGROUND Teaching clinical reasoning is a challenge in medical education. AIM To design a clinical reasoning assessment instrument. MATERIAL AND METHODS Structured interviews were carried out to six physicians with at least five years experience. The Grounded Theory method was used to determine the relevant categories of the clinical reasoning process and the modified Delphi expert judgment method to validate the categories, the definition of observable behaviors and the format of the instrument. RESULTS The relevant reasoning categories were the reason for consultation, medical history, physical examination, additional tests, diagnosis, therapeutic options and reasoning reassessment capacity. Expert judgment assessed at a level of "strongly agree" and "agree" the sufficiency, clarity and pertinence of all categories, related observable behaviors and instrument format. The internal Kappa consistency yielded an index of 0.92. CONCLUSIONS The resulting instrument was constructed with the following axes derived from the main categories and subcategories: reason for consultation, history, physical examination, additional tests, diagnosis, therapeutic options and reassessment capacity.

Abstract
The most frequent sequelae following a translabyrinthine approach for vestibular schwannoma resection is complete hearing loss on the affected side. Such patients could benefit from a cochlear implant, provided that two essential requisites are met before surgery: a preserved cochlear nerve and a patent cochlea to accommodate the electrode array. The goal of our study is to determine the prevalence and extent of cochlear ossification following a translabyrinthine approach. Postoperative MRI of 41 patients were retrospectively reviewed. Patients were classified according to the degree of cochlear obliteration into three groups (patent cochlea, partially obliterated cochlea and totally obliterated cochlea). The interval between surgery and the first MRI was studied as well as its relationship with the rate of cochlear ossification. At first postoperative MRI (mean interval of 20 months), 78% of patients showed some degree of cochlear ossification. Differences were found in the time interval between surgery and first MRI for each group, showing a smaller interval of time the patent cochlea group (p > 0.05). When MRI was performed before the first year after surgery, a larger rate of patent cochlea was found (p > 0.05). The present study suggests that cochlear ossification is a time-depending process, whose grounds are still to be defined.

Abstract
Se presenta un estudio prospectivo protocolizado de los resultados obtenidos tras el tratamiento quirúrgico de la artrosis trapecio-metacarpiana mediante la artroplastia total no cementada tipo ARPE®. Ciento cuarenta artroplastias tipo ARPE® fueron colocadas en 126 pacientes. Ciento treinta y dos muñecas corresponden a mujeres (94,3%) y 8 a hombres (5,7%) con una edad media de 58,1 años (rango: 39-79). Con seguimiento promedio de 53,8 meses (rango: 24-102), observamos una mejora importante del dolor según la escala analógica visual, 3 muñecas (2,1%) tiene una puntuación 4, 19 muñecas (13,6%) tiene una puntuación 3, 42 muñecas (30%) tiene una puntuación 2, 51 muñecas (36,4%) tiene una puntuación 1 y 25 muñecas (17,9%) tiene una puntuación 0. La movilidad promedio de la articulación trapecio-metacarpiana fue de 21,7º de antepulsión, 34,2º de retropulsión, abducción 31,9º y aducción 23,5º medida según los criterios de la Internacional Federation of Societies for Surgery of the Hand y una oposición según la escala de Tubiana de 7 en un 95,7% de las muñecas. El valorpromedio de la fuerza de puño fue de 26,5 kg, de la fuerza lateral de 9,2 kg y de la fuerza de pinza de 8,6 kg y conservaron la longitud normal del pulgar todas las muñecas intervenidas excepto una. La recuperación postoperatoria de los pacientes fue rápida y con mínimo dolor postoperatorio. Las complicaciones que se produjeron fueron 6 luxaciones (4,3%), una falsa vía del vástago (0,7%) y 2 fracturas del borde radial del trapecio intraoperatorias sin repercusión clínica (1,4%). Cinco de las 7 complicaciones graves, 4 luxaciones y la falsa vía del vástago metacarpiano se produjeron en los primeros 22 pacientes intervenidos (curva de aprendizaje). Las pequeñas desalineaciones de los componentes protésicos se toleran sin que exista una repercusión clínica en los pacientes, sobre todo las del vástago metacarpiano. Existe una supervivencia a medio plazo (5-8 años) del 100% de los implantes en nuestra serie. Un 92,9% expresaron estar satisfechos con la intervención y un 96,4% volvería a operarse con la misma técnica si fuera necesario. El valor medio obtenido tras la realización del cuestionario Disability of the Arm, Shoulder and Hand fue de 17,2. La evaluación a medio plazo de la artroplastia total no cementada tipo ballsocked de ARPE® confirma que puede ser una alternativa quirúrgica en la artrosis trapecio-metacarpiana tipo III de Eaton y Littler, teniendo en cuenta el período de aprendizaje.

Abstract
To support the construction of experiments at the Laboratorio Subterráneo de Canfranc (LSC) in Spain, an Ultra-Low Background Service (ULBS) and a Copper Electroforming Service (CES) were created. The measurement technique employed at the ULBS is gamma spectroscopy with high purity germanium (HPGe) detectors. A new anti-radon system is being implemented. The main goal of CES is to obtain high-purity copper pieces. A new electroforming set-up inside LSC underground clean room is planned. Radon and environmental measurements at the LSC are presented. The ULBS and CES are reviewed.

Abstract
BACKGROUND We hypothesized that the clinical course of venous thromboembolism in patients with active cancer may differ according to the specificities of primary tumor site. AIM AND METHODS We used data from RIETE (international registry of patients with venous thromboembolism) to compare the clinical venous thromboembolism-related outcomes during the course of anticoagulation in patients with one of the 4 more frequent cancers (breast, prostate, colorectal, or lung cancer). RESULTS As of September 2014, 3947 cancer patients were recruited, of whom 938 had breast, 629 prostate, 1189 colorectal, and 1191 lung cancer. Overall, 55% had metastatic disease (42%, 36%, 53%, and 72%, respectively). During the course of anticoagulant therapy (mean duration, 139 days), the rate of thromboembolic recurrences was similar to the rate of major bleeding in patients with breast (5.6 [95% confidence interval (CI), 3.8-8.1] vs 4.1 [95% CI, 2.7-5.9] events per 100 patient-years) or colorectal cancer (10 [95% CI, 7.6-13] vs 12 [95% CI, 9.4-15] per 100 patient-years). In contrast, in patients with prostate cancer, the rate of venous thromboembolic recurrences was half the rate of major bleeding (6.9 [95% CI, 4.4-10] vs 13 [95% CI, 9.2-17] events per 100 patient-years), whereas in those with lung cancer, the rate of thromboembolic recurrences was twofold higher than the rate of major bleeding (27 [95% CI, 22-23] vs 11 [95% CI, 8.6-15] per 100 patient-years). CONCLUSIONS Significant differences in the clinical profile of venous thromboembolic-related outcomes were observed according to the site of cancer. These findings suggest the development of cancer-specific anticoagulant strategies as an area for further research.

Abstract
In order to determine the effect of a dam on metal concentrations in riverine fish species, we studied fish inhabiting the influent (Cachapoal River) and effluent (Rapel River) of the Rapel Reservoir in central Chile. Heavy metals were quantified in gills, liver and muscle of the catfish Trichomycterus areolatus and the silverside Basilichthys microlepidotus. Also, the bioaccumulation index (BAI) was estimated by considering heavy metal concentrations obtained from water and sediment. Results showed the presence of Al, Cu, Fe, Mn, Pb and Zn in the fish organs. The analysis showed high metal concentrations in catfish inhabiting the influent compared to those collected in the effluent. These results indicate a possible filter effect of the dam for most of the metals identified in the fish organs, because metal concentrations decreased in the effluent. Finally, catfish exhibited a larger BAI for most metals analyzed.

Abstract
Asbestos and non-asbestos containing brake products are currently used in low- and middle-income countries like Colombia. Because brake products are distributed detached from their supports, they require manipulation before installation, which release fibers and expose workers. Previous studies of our research group have documented exposures in excess of the widely accepted 0.1 f/cm(3) exposure guideline. The aim of this study is to identify factors associated with non-compliance of the 8-h time weighted average (TWA) 0.1 f/cm(3) asbestos occupational limit among brake mechanics (i.e. riveters). Eighteen brake repair shops (BRS) located in Bogotá (Colombia) were sampled during 3 to 6 consecutive days for the entire work-shift. Personal and short-term personal samples were collected following NIOSH methods 7400 and 7402. Longitudinal based logistic regression models were used to determine the association between the odds of exceeding the 8-h TWA 0.1 f/cm(3) asbestos occupational limit and variables such as type of tasks performed by workers, workload (number of products manipulated daily), years of experience as riveters, and shop characteristics. These models can be used to estimate the odds of being currently or historically overexposed when sampling data do not exist. Since the information required to run the models can vary for both retrospective and current asbestos occupational exposure studies, three models were constructed with different information requirements. The first model evaluated the association between the odds of non-compliance with variables related to the workload, the second model evaluated the association between the odds of non-compliance with variables related to the manipulation tasks, and the third model evaluated the association between the odds of non-compliance with variables related with both the type of tasks performed by workers and the workload. Variables associated with the odds of non-compliance included conducting at least one manipulation activity with beveling and grinding of asbestos and non-asbestos containing brake products during the work shift, the location of the worker in the shop during non-manipulation activities, cleaning activities of the manipulation area, the years of experience working as riveters, and the number of asbestos and non-asbestos containing brake products manipulated daily. These models could be useful for current and retrospective occupational studies, in determining the odds of non-compliance of the asbestos occupational limit among brake mechanics.

Abstract
OBJECTIVES To evaluate the effect of dialysable leucocyte extract (DLE) on pro- and anti-inflammatory profiles in a rat model of osteoarthritis (OA). METHOD Forty-eight male Wistar rats were divided into three groups: normal rats without treatment, OA rats treated with placebo, and OA rats treated with DLE. After treatment, the animals were killed to obtain cartilage for histological analysis and to determine the expression of pro- and anti-inflammatory cytokines by reverse transcription multiplex polymerase chain reaction (RT-MPCR) and immunohistofluorescence analyses. RESULTS Histological analysis revealed that OA cartilage from rats treated with DLE displayed similar characteristics to non-OA cartilage from the control group. The OA cartilage treated with placebo showed alterations in the cellular architecture and in chondrocyte cluster formation. Analysis of cytokine expression by RT-MPCR showed that OA cartilage from DLE-treated rats expressed platelet-derived growth factor (PDGF), interferon (IFN)-γ, and fibroblast growth factor (FGF)-2, similar to non-OA cartilage from the control group. However, OA cartilage from rats treated with placebo expressed interleukin (IL)-1, PDGF, and I kappa B (IκB). Confocal immunodetection of FGF-2, PDGF, and non-phosphorylated IκB showed that they were distributed in the cytoplasm of most chondrocytes in OA cartilage from DLE-treated rats whereas no nuclear factor kappa B (NF-κB) expression was observed in the nuclei. Instead, in OA cartilage from the placebo group, only weak FGF-2 staining was observed, PDGF and IκB were not detected, and NF-κB was strongly observed in both cytoplasm and nuclei. CONCLUSIONS Our findings suggest that DLE treatment modifies the OA process, promoting the expression of anti-inflammatory cytokines and diminishing the inflammatory effects, avoiding the nuclear translocation of NF-κB in chondrocytes.

Abstract
Abstract. Transcranial electrical stimulation (tES) is a safe, painless, and inexpensive noninvasive brain stimulation (NIBS) technique. tES has been shown to reduce symptoms in a variety of neuropsychiatric conditions such as depression, schizophrenia, anxiety, autism, and craving. There are many factors that can influence the effects of tES, such as current intensity, duration, baseline level of activity, gender, and age. Age is a critical variable, since the human brain undergoes several anatomic and functional changes across the lifespan. Therefore, tES-induced effects may not be the same across the lifespan. In this review we summarize the effects of tES, including tDCS, tACS, and tRNS, on clinical outcomes in several neuropsychiatric conditions, using a framework in which studies are organized according to the age of subjects. The use of tES in neuropsychiatric disorders has yielded promising results with mild, if any, adverse effects. Most of the published studies with tES have been conducted with tDCS in adult population. Future studies should focus on interventions guided by surrogate outcomes of neuroplasticity. A better understanding of neuroplasticity across the lifespan will help optimize current tES stimulation parameters, especially for use with children and elderly populations.
