Abstract
PREMISE The western North American fern genus Pentagramma (Pteridaceae) is characterized by complex patterns of ploidy variation, an understanding of which is critical to comprehending both the evolutionary processes within the genus and its current diversity. METHODS We undertook a cytogeographic study across the range of the genus, using a combination of chromosome counts and flow cytometry to infer ploidy level. Bioclimatic variables and elevation were used to compare niches. RESULTS We found that diploids and tetraploids are common and widespread, and triploids are rare and sporadic; in contrast with genome size inferences in earlier studies, no hexaploids were found. Diploids and tetraploids show different geographic ranges: only tetraploids were found in the northernmost portion of the range (Washington, Oregon, and British Columbia) and only diploids were found in the Sierra Nevada of California. Diploid, triploid, and tetraploid cytotypes were found to co-occur in relatively few localities: in the southern (San Diego County, California) and desert Southwest (Arizona) parts of the range, and along the Pacific Coast of California. CONCLUSIONS Tetraploids occupy a wider bioclimatic niche than diploids both within P. triangularis and at the genus-wide scale. It is unknown whether the wider niche of tetraploids is due to their expansion upon the diploid niche, if diploids have contracted their niche due to competition or changing abiotic conditions, or if this wider niche occupancy is due to multiple origins of tetraploids.

Abstract
Honey bee colonies have great societal and economic importance. The main challenge that beekeepers face is keeping bee colonies healthy under ever-changing environmental conditions. In the past two decades, beekeepers that manage colonies of Western honey bees (Apis mellifera) have become increasingly concerned by the presence of parasites and pathogens affecting the bees, the reduction in pollen and nectar availability, and the colonies' exposure to pesticides, among others. Hence, beekeepers need to know the health condition of their colonies and how to keep them alive and thriving, which creates a need for a new holistic data collection method to harmonize the flow of information from various sources that can be linked at the colony level for different health determinants, such as bee colony, environmental, socioeconomic, and genetic statuses. For this purpose, we have developed and implemented the B-GOOD (Giving Beekeeping Guidance by computational-assisted Decision Making) project as a case study to categorize the colony's health condition and find a Health Status Index (HSI). Using a 3-tier setup guided by work plans and standardized protocols, we have collected data from inside the colonies (amount of brood, disease load, honey harvest, etc.) and from their environment (floral resource availability). Most of the project's data was automatically collected by the BEEP Base Sensor System. This continuous stream of data served as the basis to determine and validate an algorithm to calculate the HSI using machine learning. In this article, we share our insights on this holistic methodology and also highlight the importance of using a standardized data language to increase the compatibility between different current and future studies. We argue that the combined management of big data will be an essential building block in the development of targeted guidance for beekeepers and for the future of sustainable beekeeping.

Abstract
Pollination is a crucial ecosystem service for maintaining plant communities and food production. 75% of the main crops depend on or benefit from pollination services provided by animal pollinators. However, when these services are insufficient and/or inefficient, crops experience pollen limitation with, often, lower associated yield, which may translate into economic losses. We constructed a global dataset that gathers studies with pollination experiments, aiming to provide pollen limitation values of animal-pollinated crops worldwide. Pollination experiments included hand pollen supplementation treatments, where plants were subjected to pollen supplementation of outcross pollen, and natural pollination treatments. The PolLimCrop dataset comprises 294 studies and 1169 unique pollen supplementation experiments with values of pollen limitation for 108 crops, spanning 50 years and 62 countries.

Abstract
An essential prerequisite to safeguard pollinator species is characterisation of the multifaceted diversity of crop pollinators and identification of the drivers of pollinator community changes across biogeographical gradients. The extent to which intensive agriculture is associated with the homogenisation of biological communities at large spatial scales remains poorly understood. In this study, we investigated diversity drivers for 644 bee species/morphospecies in 177 commercial apple orchards across 33 countries and four global biogeographical biomes. Our findings reveal significant taxonomic dissimilarity among biogeographical zones. Interestingly, despite this dissimilarity, species from different zones share similar higher-level phylogenetic groups and similar ecological and behavioural traits (i.e. functional traits), likely due to habitat filtering caused by perennial monoculture systems managed intensively for crop production. Honey bee species dominated orchard communities, while other managed/manageable and wild species were collected in lower numbers. Moreover, the presence of herbaceous, uncultivated open areas and organic management practices were associated with increased wild bee diversity. Overall, our study sheds light on the importance of large-scale analyses contributing to the emerging fields of functional and phylogenetic diversity, which can be related to ecosystem function to promote biodiversity as a key asset in agroecosystems in the face of global change pressures.

Abstract
BACKGROUND The optimisation of the use of β-lactam antibiotics (BLA) via prolonged infusions in life-threatening complications such as febrile neutropenia (FN) is still controversial. This systematic review and meta-analysis aim to evaluate the efficacy of this strategy in onco-haematological patients with FN. METHODS A systematic search was performed of PubMed, Web of Science, Cochrane, EMBASE, World Health Organization, and ClinicalTrials.gov, from database inception until December 2022. The search included randomised controlled trials (RCTs) and observational studies that compared prolonged vs short-term infusions of the same BLA. The primary outcome was all-cause mortality. Secondary outcomes were defervescence, requirement of vasoactive drugs, length of hospital stay and adverse events. Pooled risk ratios were calculated using random effects models. RESULTS Five studies were included, comprising 691 episodes of FN, mainly in haematological patients. Prolonged infusion was not associated with a reduction in all-cause mortality (pRR 0.83; 95% confidence interval 0.47-1.48). Nor differences were found in secondary outcomes. CONCLUSIONS The limited data available did not show significant differences in terms of all-cause mortality or significant secondary outcomes in patients with FN receiving BLA in prolonged vs. short-term infusion. High-quality RCTs are needed to determine whether there are subgroups of FN patients who would benefit from prolonged BLA infusion.

Abstract
BACKGROUND Mating system is one of the major determinants of intra- and interspecific genetic structure, but may vary within and between plant populations. Our study model included all known populations of Moehringia tommasinii (Caryophyllaceae), a narrow endemic plant inhabiting rock crevices in the northwestern Adriatic, and some populations of co-occurring and widespread M. muscosa, an ecologically divergent relative with an overlapping flowering period. We performed reciprocal crosses within and between taxa and used molecular markers to assess the extent of gene flow within and between populations and taxa. Using coefficient of inbreeding, population size, seed weight, pollen-to-ovule ratio, and flower display size, we also looked for evidence of a selfing syndrome. RESULTS A surprisingly high variation in mating systems was observed among populations of M. tommasinii. These populations exhibited genetic structuring, with their size positively correlated with both seed weight and pollen production. Although a selfing syndrome could not be confirmed as the majority of selfing resulted from allogamous treatments, the occurrence of selfing was notable. In the presence of M. muscosa, at a site where both species coexist closely, a distinct pattern of fruit production was observed in M. tommasinii following various pollination treatments. Molecular and morphometric data provided evidence of hybridization followed by local extinction at this site. CONCLUSIONS Population size proved to be the most important factor affecting the mating system in genetically structured populations of M. tommasinii. Lighter seeds and lower pollen production observed in populations with pronounced selfing do not provide enough evidence for the selfing syndrome. Detected gene flow between M. tommasinii and the sympatric M. muscosa suggested weak reproductive barriers between the taxa, which could pose a conservation problems for the former species. Hybridization leading to local extinction may also resulted in floral polymorphism and disruption of mating patterns of M. tommasinii.

Abstract
PREMISE The relationships between reproductive investment, phenotype, and fitness have been broadly studied in cross-pollinated plants in contrast to selfing species, which are considered less interesting in this area because they are supposed to be a dead end in any evolutionary pathway. Still, selfing plants are unique systems to study these questions since the position of reproductive structures and traits related to flower size play an important role in female and male pollination success. METHODS Erysimum incanum s.l. is a selfing species complex that has three levels of ploidy (diploids, tetraploids, and hexaploids) and traits that are typically associated with the selfing syndrome. Here, we used 1609 plants belonging to these three ploidies to characterize the floral phenotype and spatial configuration of reproductive structures, reproductive investment (pollen and ovule production), and plant fitness. Then, we used structural equation modelling to analyze the relationship between all these variables across ploidy levels. RESULTS An increase in ploidy level leads to bigger flowers with anthers exserted farther and more pollen and ovules. In addition, hexaploid plants had higher absolute values for herkogamy, which is positively correlated with fitness. Ovule production significantly mediated the natural selection acting on different phenotypic traits and pollen production, a pattern that is maintained across ploidies. CONCLUSIONS The changes in floral phenotypes, reproductive investment, and fitness with ploidy level suggest that genome duplication can be a driver for transitions in reproductive strategy by modifying the investment in pollen and ovules and linking them with plant phenotype and fitness.

Abstract
Polyploidy has important ecological effects, including ploidy-mediated effects on morphology, breeding system and ecological tolerances. However, there is still little comprehensive research available to test its adaptive significance and its role in driving distributional patterns. This work aimed to assess the contribution of genome duplications to ecological divergence using an experimental approach with the diploid-tetraploid Jasione maritima polyploid complex. We explored if individuals with different ploidy differ in their tolerance to water deficit and if this may contribute to explaining the distribution patterns along a latitudinal gradient in the northwest Iberian Peninsula. For that, we used three cytogenetic entities: diploids and established tetraploids collected in natural populations along a latitudinal gradient, and neotetraploids synthesized from diploid populations after treatments with colchicine. Thirty plants from each of the nine populations were grown under controlled conditions with half randomly assigned to the water deficit treatment, and half used as control. We determined experimental plants' response by measuring fitness-related parameters, such as above and belowground biomass, plant water status, photosynthetic efficiency and pigments, membrane stability, antioxidant capacity and sugars content. Our data shows that biomass, chlorophyll content, photochemical quenching (qP) and non-photochemical quenching (NPQ) in neotetraploids and established tetraploids were significantly higher than in diploids and that these differences could be attributed to genome duplications. In response to the water deficit, diploids seem to use a strategy of avoidance, whereas tetraploids seem to employ the strategy of tolerance to overcome water deficit stress, which appears equally efficient. Additionally, we did not observe a response pattern along the latitudinal gradient of the distributional range of the J. maritima complex. The results indicate that the response to water deficit is population dependent. Further studies are necessary to understand the role of ploidy in explaining the distribution patterns of the J. maritima complex.

Abstract
Introduction The high frequency of polyploidy in the evolutionary history of many plant groups occurring in the Mediterranean region is likely a consequence of its dynamic paleogeographic and climatic history. Polyploids frequently have distinct characteristics that allow them to overcome the minority cytotype exclusion. Such traits may enable polyploid individuals to grow in habitats different from their parentals and/or expand to new areas, leading to spatial segregation. Therefore, the successful establishment of polyploid lineages has long been associated with niche divergence or niche partitioning and the ability of polyploids to cope with different, often more stressful, conditions. In this study, we aimed to explore the role of environmental variables associated with the current distribution patterns of cytotypes within the polyploid complex Linum suffruticosum s.l.. Methods The distribution and environmental niches of the five main cytotypes of Linum suffruticosum s.l. (diploids, tetraploids, hexaploids, octoploids and decaploids) were studied across its distribution range. Realized environmental niche of each cytotype was determined using niche modelling tools, such as maximum entropy modelling and niche equivalency and similarity tests. Results Differences in the environmental conditions of L. suffruticosum s.l. cytotypes were observed, with polyploids being associated with habitats of increased drought and soil pH, narrower temperature ranges and decreased soil water and cation exchange capacities. Diploids present the widest environmental niche, and polyploids occupy part of the diploid niche. Although some polyploids have equivalent potential ecological niches, cytotypes do not co-occur in nature. Additionally, the ecological niche of this polyploid complex is different between continents, with North African habitats being characterised by differences in soil texture, higher pH, and low cation exchange capacity, precipitation and soil water capacity and higher temperatures than habitats in southwest Europe. Discussion The different ecological conditions played a role in the distribution of cytotypes, but the mosaic distribution could not be entirely explained by the environmental variables included in this study. Other factors, such as reproductive isolation and competitive interactions among cytotypes, could further explain the current diversity and distribution patterns in white flax. This study provides relevant data on the niche requirements of each cytotype for further competition and reciprocal transplant experiments. further competition and reciprocal transplant experiments.

Abstract
Flow cytometry has emerged as a uniquely flexible, accurate, and widely applicable technology for the analysis of plant cells. One of its most important applications centers on the measurement of nuclear DNA contents. This chapter describes the essential features of this measurement, outlining the overall methods and strategies, but going on to provide a wealth of technical details to ensure the most accurate and reproducible results. The chapter is aimed to be equally accessible to experienced plant cytometrists as well as those newly entering the field. Besides providing a step-by-step guide for estimating genome sizes and DNA-ploidy levels from fresh tissues, special attention is paid to the use of seeds and desiccated tissues for such purposes. Methodological aspects regarding field sampling, transport, and storage of plant material are also given in detail. Finally, troubleshooting information for the most common problems that may arise during the application of these methods is provided.

Abstract
BackgroundGiven the progressive change in the management of inflammatory diseases,an observational study was conducted on the management of Early Rheumatoid Arthritis (ERA) in Catalonia.ObjectivesTo know the management of ERA in Catalonia, to assess whether the recommendations of the EULAR/ACR guidelines are followed and to study the causes of management variability,to set improvement objectives.MethodsAn observational,descriptive,and cross-sectional study was conducted,with data collection from June 15 to 30, 2021.The rheumatologists’ partners of the Catalan Society of Rheumatology were the object of study. An online survey was conducted with 304 members on the management of the ERA. Variables related to the characteristics of the respondents,the derivation and variables of the disease including clinical variables,type of treatment and outcomes used for follow-up including the impact of the SARS-CoV2 pandemic were included.The univariate study was performed using a study of proportions with Pearson’s correlation.ResultsA total of 105 members (34.5%) responded to the survey.11.6%>60 y, only 7.8% <30y. 99% were in public assistance.The number of rheumatologists per service is 7.2[1-17],but 34.2% had< 5 rheumatologists,with a reference population of 200,000-300,000p in 42% of respondents.The number of weekly visits made is 67.5[20-130].42.2% do not have a monographic RA or ERA dispensary and 30.4%not have specialized nursing.Characteristics of ERA:77.5% are derived from primary care(PC),52% have been between 6 weeks,42.1%>3 months.54.9% make a first visit within 2-4 weeks of PC referral and 14.7%> 8 weeks.100%provide previous analysis,only 47% had had RX performed.98% were previously treated(50.4%NSAIDs + CG,36.1%NSAIDs,12.3% CG).4.3% had GC doses>10 mg/day,11.3%> to 20mg/day.The treatment:DMARDs of choice in 100% is MTX,44.1% start doses of 10mg/week and 3.9%7.5 mg/week.The route of choice is oral(55.9% vs 44.1%).92.2% associate GC and 31.7% have not withdrawn them after 6 m.57.8% consider the maximum of MTX 25mg/W.87.1% use doses<10 mg/day,with the most used dose being 5 mg/day(35.6%).Follow-up after the start of DMARDs is performed 72.5% between 4-6 weeks and 12.7% is performed by nursing.100% use DAS 28 and 53.5% also CDAI.31.4% perform PROs(HAQ 83.3%,RAPID 3 14.3%).The use of systematic ultrasound is collected in 33%, being himself who performs it in 59.9% and an expert rheumatologist in 46.1%.Finally, when asked about incidence of pandemic in the follow-up,53.3% consider that it is doing the same as before. 46.1% consider that telephone visits are not suitable for the follow-up of the ERAvs14.7% who consider that Yes.When questioning the situations in which they consider them to be appropriate,75.9% that it was adequate in the control after the beginning of the DMARDs.Regarding the treatment of ERA, 66% delayed the onset of biological DMARDs, 72.1% due to difficulty of follow-up and only 8.8% due to an increased risk of infection. When performing the univariate analysis, it is evident that having a monographic dispensary is associated with earlier onset of MTX(p< 0.001)and at doses≥15 mg/W(p = 0.05),greater nursing intervention(p< 0.001),greater use of PROs(p = 0.008)and there is a tendency to a shorter waiting time for first visits(p = 0.07).It is also associated with not considering telephone visits(p< 0.001), making them in less than 25%(p< 0.0001).Similarly,hospital level is directly proportional to initiation at higher doses of MTX(p< 0.0001),lower use of GC<10mg.Among the rest of the variables, no association has been found.ConclusionThe recommendations of EULAR/ACR in the treatment and follow-up of ERA are consistently followed,although the wide use of MTX orally is striking.It is evident that the variable that most influences the early onset of FAME and at higher doses,is a monographic dispensary,as well as greater presence of nursing and performance of PROs.AcknowledgementsThanks to all the members of the Catalan society of reuamtology who participated in the surveyDisclosure of InterestsNone declared

Abstract
BackgroundFatigue in RA has a multi-causal pathway. It is recommended that it should be measured in all RA studies using a validated instrument. Fatigue in elderly patients could have a different perception than in younger patients, identifying the associated factors could be a key to the management of this complex symptom.ObjectivesTo compare fatigue and its associated factors in young and elderly patients with RA from two university hospitals.MethodsA cross-sectional analysis was performed in 167 RA patients diagnosed according to the 2010 ACR-EULAR criteria. Patients were divided into two groups based on age (≥60 and <60) for comparative purposes. Fatigue was assessed using 4 instruments: the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ), the fatigue subscale of the Short-form 36 survey (fatigue-SF36), the Visual Analogic scale of fatigue (VASf) and the Functional Assessment of chronic illness Therapy Fatigue Scale (FACIT-F). To compare the mean of fatigue between groups we used a T-Test.To determine in each group of patients (young and elderly patients) the relationship between the 4 subscales of fatigue (assessed by BRAF-MDQ) and the other variables (DAS28, CPR, ESR, hemoglobin, vitamin D, HAQ, RAID [Rheumatoid Arthritis Impact of Disease], SF36, Hospital Anxiety and depression Scale [HAD] and Brief Pain Inventory) a Spearman correlation was performed. A value of p < 0.05 was accepted as statistically significant.ResultsA total of 167 patients were included, 81 (48.5%) young and 86 (51.5%) elderly patients. We found fatigue (using 4 instruments) has not significant differences in young and elderly patients (Table 1). In young and elderly patients, physical, living, cognitive and emotional fatigue were correlated to RAID, SF36, HAD and pain but they were not associated to CRP, ESR, hemoglobin and vitamin D. In young patients, all dimensions of fatigue were associated with DAS28. Furthermore, in elderly patients we found a relationship between physical (p-value 0.044) and living fatigue (p-value 0.012) with DAS28, nevertheless cognitive and emotional fatigue (p-value 0.078 and 0.079 respectively) were not related.Table 1.Scores of the Fatigue Questionnaires used to assess fatigue in young and elderly patients with RA.Young Mean (SD)Elderly Mean (SD)p-valueFACIT-F36.5 (12.5)35.9 (11.7)0.2963VAS-F4.3 (2.8)3.8 (2.8)0.119SF36-Fatigue50.9 (23.9)51.0 (21.9)0.628BRAF-MDQ Physical9.2 (6.2)8.5 (6.3)0.4670 Living5.3 (5.6)4.2 (4.6)0.1446 Cognitive3.3 (3.8)4.2 (4.6)0.2932 Emotional3.5 (3.5)2.6 (2.7)0.0932ConclusionIn young and elderly patients, all dimensions of fatigue appear to be related with subjective but not with objective variables. In young patients, all dimensions of fatigue were associated with DAS28 but in elderly patients only physical and living fatigue were correlate to disease activity. These results could indicate that it is important to evaluate fatigue in a multidimensional perspective in elderly patients.References[1]Belza BL, Henke CJ, Yelin EH, Epstein WV, Gilliss CL.

Abstract
Introduction Delirium is characterized as a short-term consciousness and cognition disturbance which tends to fluctuate during the course of the day. It is a common and serious problem, mainly in hospitalized older adults, potentially avoidable and often poorly recognized. Objectives We propose an analysis on the theme through a work that evaluates the requests for psychiatric consultation made in a district hospital in Portugal during the course of 12 months. Methods We identified all patients on the requests for psychiatric consultation and obtained a demographic, clinical and consultation requests by medical specialties data and conducted statistical analysis using Excel. Results We identified 106 consultation requests, in which 41 cases were eventually diagnosed as delirium. Most (83%) were hyperactive delirium, 12% were hypoactive delirium and 5% were mixed delirium. Incidence was higher in males (59%) and in those aged between 66 and 80 years old (56.1%). Most consultation requests were made by Internal Medicine (46.3%), followed by General Surgery (26.8%), Pulmonology (14.6%), Orthopedics (9.8%) and Neurology (2.5%). Finally, we analyzed which symptoms mentioned in the request made physicians consider requesting a psychiatric evaluation. Approximately half of the cases (48.8%) reported psychomotor agitation, followed by temporal/spatial disorientation (41.5%) and aggressive behaviour (17.1%). Conclusions We highlight a still notorious lack of proper identification of delirium, resulting in symptoms being incorrectly interpreted as a psychiatric disorder. This may cause a delay in the adequate diagnosis and management of the condition, increasing the morbidity and mortality of patients. Disclosure No significant relationships.

Abstract
BackgroundAdalimumab remains the only biologic approved by the EMA and FDA for the treatment of non-infectious uveitis [1-6]. The reports on efficacy of other anti-TNF drugs such as Certolizumab Pegol (CZP) are scarce.Objectivesto determine the efficacy and safety of CZP in refractory uveitis secondary to Immune-mediated Inflammatory Diseases (IMIDs).Methodsnational multicenter study of 80 patients with uveitis due to IMID refractory to glucocorticoids and conventional immunosuppressants treated with CZP. Efficacy was assessed with the following ocular parameters: best corrected visual acuity (BCVA), anterior chamber cells, vitritis, macular thickness and presence of retinal vasculitis. The efficacy of CZP was compared between the baseline visit, 1st week, 1st and 6th month, and 1st year. Statistical analysis was performed with IBM SPSS Statistics v.23.Resultswe studied 80 patients/111 affected eyes (33 men/47 women) with a mean age of 41.6±11.7 years. The IMIDs included were: spondyloarthritis (n=43), Behçet’s disease (10), psoriatic arthritis (8), Crohn’s disease (4), sarcoidosis (2), JIA (1), reactive arthritis (1), rheumatoid arthritis (1), relapsing polychondritis (1), TINU (1), pars planitis (1), Birdshot (1) and idiopathic uveitis (6). Anterior was the most frequent uveitis pattern (n=61).In 20 patients, besides the presence of refractory uveitis, desire of pregnancy was the reason for CZP initiation.Prior to CZP, patients had received: methotrexate (n=38), sulfasalazine (28), azathioprine (14), cyclosporine (10), leflunomide (3), mycophenolate mofetil (4), and cyclophosphamide (1). Previous biologic therapy was administered in 52 patients (63%), with a median [IQR] of 2 [1-3] drugs per patient. The most used biologic was adalimumab (n=48), followed by infliximab (32), golimumab (15), tocilizumab (5), etanercept (7), rituximab (1), anakinra (1) and secukinumab (1). CZP was administered as monotherapy in 39 patients.After 24 [12-36] months of follow-up, all parameters analyzed showed a rapid and maintained improvement (Table 1). A decrease in the mean number of uveitis flares was observed before and after CZP, (2.6±2.3 vs. 0.6±0.4, p<0.001). CZP was discontinued in 16 patients due to: ocular remission (n=3), insufficient ocular response (4) and incomplete response of extraocular manifestations (9). No serious adverse effects were found.Table 1.main ocular parameters analyzed in 80 patients with uveitis due to IMID and treated with CZP.Baseline1st week1st month3rd month6th month1st yearBCVA (mean±SD)0.68±0.270.73±0.26*0.79±0.26*0.82±0.25*0.85±0.24*0.86±0.23*Tyndall improvement, n (%)Patients with Tyndall + at baseline (n=57)-23 (40.3)45 (78.9)47 (82.4)57 (100)57 (100)Vitritis improvement, n (%)Patients with Vitritis at baseline (n=14)-5 (35.7)8 (57.1)13 (92.8)14 (100)14 (100)OCT (µm) (mean±SD)297.5±48.1297.1±45.5286.5±39.8*277.6±43.3*271.5±38.6*269.0±38.8*Choroiditis, affected eyes, n (%)3 (2.4)3 (2.4)2 (1.6)2 (1.6)1 (0.8)1 (0.8)Retinal vasculitis, affected eyes, n (%)3 (2.4)2 (1.6)1 (0.8)0 (0)0 (0)0 (0)*p<0.01ConclusionCZP seems to be effective and safe in the control of uveitis associated to different IMIDs.References[1]Jaffe GJ, et al.

Abstract
Introduction Epidemiological studies suggested that antidepressant usage amongst pregnant women increased by 3-
to 7-fold in the past 2 decades and that up to 13% of fetuses are exposed to antidepressants. There are concerns regarding the impact of prenatal antidepressant use on the offspring. Objectives We aim to review more recent evidence of antidepressant use during pregnancy and the risk of autism spectrum disorder (ASD) in the offspring. Methods Non-systematic review based on the PubMed® database. Results A recent meta-analyses suggested children of mothers who used antidepressants during their pregnancy may be at a higher risk of ASD, compared to mothers who do not use these medications. Other suggested that the use of any antidepressants in the first 2 trimesters was related to significantly risk of developing ASD. Despite higher risks with the use of antidepressants, the absolute risk appears to be low. In addition, confounding factors should be considered while interpreting the results. Studies concluded that the comparator group selection strongly influences the observed antidepressant-ASD relationship. Associations derived from general population studies might have been mediated by unmeasured maternal psychiatric burden or transdiagnostic genetic liability. The observed increase in risk may also be associated with depression, not its treatment. Conclusions The findings of these studies have important implications, and often result in drug discontinuation with a significant impact on maternal and infant health. Future research should include investigation of the severity of depression in this association, assessment of antidepressant dose and use of antidepressants in pregnant women with other pathologies.

Abstract
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and inform management actions. Here, we present CropPol, a dynamic, open and global database on crop pollination. It contains measurements recorded from 202 crop studies, covering 3,394 field observations, 2,552 yield measurements (i.e. berry weight, number of fruits and kg per hectare, among others), and 47,752 insect records from 48 commercial crops distributed around the globe. CropPol comprises 32 of the 87 leading global crops and commodities that are pollinator dependent. Malus domestica is the most represented crop (32 studies), followed by Brassica napus (22 studies), Vaccinium corymbosum (13 studies), and Citrullus lanatus (12 studies). The most abundant pollinator guilds recorded are honey bees (34.22% counts), bumblebees (19.19%), flies other than Syrphidae and Bombyliidae (13.18%), other wild bees (13.13%), beetles (10.97%), Syrphidae (4.87%), and Bombyliidae (0.05%). Locations comprise 34 countries distributed among Europe (76 studies), Northern America (60), Latin America and the Caribbean (29), Asia (20), Oceania (10), and Africa (7). Sampling spans three decades and is concentrated on 2001-05 (21 studies), 2006-10 (40), 2011-15 (88), and 2016-20 (50). This is the most comprehensive open global data set on measurements of crop flower visitors, crop pollinators and pollination to date, and we encourage researchers to add more datasets to this database in the future. This data set is released for non-commercial use only. Credits should be given to this paper (i.e., proper citation), and the products generated with this database should be shared under the same license terms (CC BY-NC-SA).

Abstract
BACKGROUND Although the number of nationwide clinical registries in upper gastrointestinal cancer is increasing, few of them perform regular clinical audits. The Spanish EURECCA Esophagogastric Cancer Registry (SEEGCR) was launched in 2013. The aim of this study was to assess the reliability of the data in terms of completeness and accuracy. METHODS Patients who were registered (2014-2017) in the online SEEGCR and underwent esophagectomy or gastrectomy with curative intent were selected for auditing. Independent teams of surgeons visited each center between July 2018 and December 2019 and checked the reliability of data entered into the registry. Completeness was established by comparing the cases reported in the registry with those provided by the Medical Documentation Service of each center. Twenty percent of randomly selected cases per hospital were checked during on-site visits for testing the accuracy of data (27 items per patient file). Correlation between the quality of the data and the hospital volume was also assessed. RESULTS Some 1839 patients from 19 centers were included in the registry. The mean completeness rate in the whole series was 97.8% (range 82.8-100%). For the accuracy, 462 (25.1%) cases were checked. Out of 12,312 items, 10,905 were available for verification, resulting in a perfect agreement of 95% (87.1-98.7%). There were 509 (4.7%) incorrect and 35 (0.3%) missing entries. No correlation between hospital volume and the rate of completeness and accuracy was observed. CONCLUSIONS Our results indicate that the SEEGCR contains reliable data.

Abstract
Habitat loss is currently a major threat to biodiversity, affecting species interactions, such as plant-pollinator interactions. This is particularly important in self-incompatible plants relying on pollinators to reproduce and sustain their populations. Here, we evaluated how habitat loss affects the pollination system, plant individual-pollinator species interaction network, and plant reproductive fitness of the self-incompatible Jasione maritima var. sabularia, a threatened taxon from dune systems. This plant is a pollinator generalist, visited by 108 species from distinct taxonomic groups. Results suggest that increasing habitat loss led to a significant decline in pollinator richness, increased pollen limitation, and a decrease in reproductive fitness of J. maritima var. sabularia. Visitation rate per individual did not significantly change with available area, indicating that the quality of pollen differed across populations. The topology of the network between J. maritima var. sabularia individuals and its pollinator species did not change, which may be attributed to the stability in the core of pollinator species. This suggests that the lower fitness of plants with increasing habitat degradation may be explained not only by the lower richness of peripheral pollinators but also by the genetic structure of the plant populations, as there is a possible higher transference of less quality pollen by pollinators, ultimately compromising the persistence of plant populations. Our study highlights the need of future studies to integrate the fine details provided by individual-level networks, which will increase our understanding of the pattern of species interactions and its consequences for the fitness of threatened plant populations.

Abstract
Depression and alcohol use disorder (AUD) greatly contribute to the burden of disease worldwide, and have large impact on Colombia's population. In this study, a qualitative analysis evaluates the implementation of a technology-supported model for screening, decision support, and digital therapy for depression and AUD in Colombian primary care clinics. Patient, provider, and administrator interviews were conducted, exploring attitudes towards depression and AUD, attitudes towards technology, and implementation successes and challenges. Researchers used qualitative methods to analyze interview themes. Despite stigma around depression and AUD, the model improved provider capacity to diagnose and manage patients, helped patients feel supported, and provided useful prevalence data for administrators. Challenges included limited provider time and questions about sustainability. The implementation facilitated the identification, diagnosis, and care of patients with depression and AUD. There is ongoing need to decrease stigma, create stronger networks of mental health professionals, and transition intervention ownership to the healthcare center.

Abstract
Additive-manufacturing is one of the major pillars of the new industrial revolution and the three-dimensional (3D) printing technology has been highlighted in this scenario. Among the many areas benefited by 3D-printing, the development of electrochemical sensors has appeared in evidence in the last years. One potential application of 3D-printed electrochemical sensors is devoted to forensic chemistry, which demands for portable analytical methods that can provide on-site measurements and thus bring a relevant information in loco. In this context, this review highlights the recent contribution of 3D-printing technology on the development of electrochemical sensors with great promises for on-site analysis in “real-world” forensic scenarios. From the detection of trace explosives, gunshot residues, illicit drugs and chemical threats, to the measurement of adulterants in food and fuels, we show the wide range of applications that 3D-printed electrochemical sensors have been proposed and future demands that can be addressed by such a powerful, affordable, and accessible tool.

Abstract
Introduction Tourette’s syndrome is a neuropsychiatric disorder marked by motor and phonic tics frequently associated with psychiatric comorbidities, beginning in childhood. While most cases improve or resolve with age, some are refractory. Objectives To review new strategies for the management of Tourette’s Syndrome, following an outpatient clinical vignette. Methods We performed a review based on the PubMed® database. Results A 50-years-old female patient with a long-term outpatient psychiatric follow-up presented with motor tics appearing in adolescence, including winking and facial grimacing, as well as episodes of coprolalia. Over the years, she developed an anxiety disorder and social isolation. In addition to psychological therapy, pharmacological therapy had already been approached with the use alpha-adrenergic agonists and several antipsychotics, such as risperidone and aripiprazole, with the patient showing only partial response to pimozide. In Tourette’s syndrome, the therapy must be adequate to the patient’s individual needs. Emerging treatments for refractory cases, such as anticonvulsants, cannabinoids or antiglutamatergic drugs have been the target of several studies. Botulinum toxin injections are particularly effective in patients with focal motor tics and complex phonic tics. Non-pharmacological treatment options, such as electroconvulsive therapy and deep brain stimulation may prove effective in some cases. Conclusions A significant proportion of patients fail to respond to conventional strategies. Thus, new pharmacological and non-pharmacological therapies are on the horizon and may represent an important step in treatment algorithms for refractory cases in the future.

Abstract
Inadequate quantity and quality of pollen reaching the stigmas decreases the sexual reproductive output of plants, compromising yield. Still, the current extent of pollen limitation affecting yield (i.e., pollination deficits) is poorly quantified. This study is aimed at quantifying pollination deficits in kiwifruit orchards, a dioecious plant with a fruit caliber and market value largely dependent on pollination services. For that, we set up a pollination experiment and quantified services and yield provided by current pollination vectors, and under optimal pollination, over two years in a total of twenty-three orchards covering the kiwifruit production range in Portugal. We characterized nine fruit traits and used: (1) fruit weight to calculate pollination deficits and relate them with pollinator diversity and abundance, and environmental variables; and (2) production values, fruit caliber, and market values to calculate economic impact of pollination deficits. Results showed that pollination deficits were variable in time and space and were significantly and negatively correlated with pollinator abundance, while the opposite pattern was obtained for production, supporting the notion that a higher pollinator's abundance is related to lower pollination deficits and higher yields. Understanding the factors affecting pollination deficits is crucial to depict the need for nature-based solutions promoting pollinators and to resort to management practices assisting pollination.

Abstract
There are no internationally recognized criteria available to determine preparedness for hospital discharge after esophagectomy. This study aims to achieve international consensus using Delphi methodology. The expert panel consisted of 40 esophageal surgeons spanning 16 countries and 4 continents. During a 3-round, web-based Delphi process, experts voted for discharge criteria using 5-point Likert scales. Data were analyzed using descriptive statistics. Consensus was reached if agreement was ≥75% in round 3. Consensus was achieved for the following basic criteria: nutritional requirements are met by oral intake of at least liquids with optional supplementary nutrition via jejunal feeding tube. The patient should have passed flatus and does not require oxygen during mobilization or at rest. Central venous catheters should be removed. Adequate analgesia at rest and during mobilization is achieved using both oral opioid and non-opioid analgesics. All vital signs should be normal unless abnormal preoperatively. Inflammatory parameters should be trending down and close to normal (leucocyte count ≤12G/l and C-reactive protein ≤80 mg/dl). This multinational Delphi survey represents the first expert-led process for consensus criteria to determine 'fit-for-discharge' status after esophagectomy. Results of this Delphi survey may be applied to clinical outcomes research as an objective measure of short-term recovery. Furthermore, standardized endpoints identified through this process may be used in clinical practice to guide decisions regarding patient discharge and may help to reduce the risk of premature discharge or prolonged admission.

Abstract
Polyploidy has played an important evolutionary role in the genus Festuca (Poaceae), and several ploidy levels (ranging from 2n = 2x = 14 to 2n = 12x = 84) have been detected to date. This study aimed to estimate the genome size and ploidy level of two subspecies belonging to the F. yvesii polyploid complex by flow cytometry and chromosome counting. The phenotypic variation of the cytotypes was also explored, based on herbarium material. The genome size of F. yvesii subsp. lagascae has been estimated for the first time. Nuclear 2C DNA content of F. yvesii subsp. summilusitana ranged from 21.44 to 31.91 pg, while that of F. yvesii subsp. lagascae was from 13.60 to 22.31 pg. We report the highest ploidy level detected for Festuca (2n = 14x = 98) and previously unknown cytotypes. A positive correlation between holoploid genome size and chromosome number counts shown herein was confirmed. The morphometric approach showed a slight trend towards an increase in the size of some organs consistent with the variation in the ploidy level. Differences in characters were usually significant only among the most extreme cytotypes of each subspecies, but, even in this case, the high overlapping ranges prevent their distinction.

Abstract
Background:Prognosis of non-infectious refractory uveitis has improved markedly with biologic therapy (BT) (1-5). Most data are with monoclonal anti-TNF drugs, especially Adalimumab (ADA) and Infliximab (IFX). However, there is not enough evidence for the use of Certolizumab Pegol (CZP).Objectives:To evaluate the efficacy and safety of CZP in refractory uveitis secondary to Immune-Mediated Inflammatory Diseases (IMID).Methods:Multicenter study of 71 patients with uveitis due to IMID refractory to glucocorticoids and conventional immunosuppressants. Efficacy was assessed with the following ocular parameters: best corrected visual acuity (BCVA), anterior chamber cells, vitritis, macular thickness and presence of retinal vasculitis. These outcomes were compared between baseline, 1st week, 1st and 6th month, and 1st and 2nd year. Statistical analysis was performed with IBM SPSS Statistics v.23.Results:71 patients/100 affected eyes (29 men/42 women) with mean age of 40.0±11.3 years were studied. Underlying IMIDs were: spondyloarthritis (n=38), Behçet (10), psoriatic arthritis (8), Crohn disease (3), sarcoidosis (2), JIA (1), reactive arthritis (1), rheumatoid arthritis (1), relapsing polychondritis (1), TINU (1), pars planitis (1), Birdshot (1) and idiopathic uveitis (3). Uveitis pattern was anterior (n=55), posterior (6), panuveitis (6) and intermediate (4).Prior to CZP, patients had received: methotrexate (37), sulfasalazine (26), azathioprine (14), cyclosporine (10), leflunomide (3), mycophenolate mofetil (3) and cyclophosphamide (1). Previous BT was administered in 48 (67.6%) patients, with a mean of 1.4±1.3 drugs per patient as follows: ADA (n=56), IFX (27), golimumab (14), tocilizumab (5) and etanercept (3). Pregnancy was the reason for prescribing CZP in 19 patients. CZP was administered in monotherapy (n=39) or combined with conventional immunosuppressants (n=32).After a mean follow-up of 27.1±21.1 months, most of the ocular variables showed a rapid and significantly improvement (Table 1). A decrease in the median number [IQR] of flares of uveitis before and after CZP, (3 [1-4] vs. 0 [0-1], p<0.001) was observed. CZP was discontinued in 15 patients due to remission (n=2), ocular insufficient response (2) and incomplete response of extraocular manifestations (11). No serious adverse events were reported.Conclusion:CZP seems to be effective and safe in patients with refractory uveitis due to IMID.References:[1]Martín-Varillas JL, et al.

Abstract
BACKGROUND Data on the long-term symptom burden in patients surviving oesophageal cancer surgery are scarce. The aim of this study was to identify the most prevalent symptoms and their interactions with health-related quality of life. METHODS This was a cross-sectional cohort study of patients who underwent oesophageal cancer surgery in 20 European centres between 2010 and 2016. Patients had to be disease-free for at least 1 year. They were asked to complete a 28-symptom questionnaire at a single time point, at least 1 year after surgery. Principal component analysis was used to assess for clustering and association of symptoms. Risk factors associated with the development of severe symptoms were identified by multivariable logistic regression models. RESULTS Of 1081 invited patients, 876 (81.0 per cent) responded. Symptoms in the preceding 6 months associated with previous surgery were experienced by 586 patients (66.9 per cent). The most common severe symptoms included reduced energy or activity tolerance (30.7 per cent), feeling of early fullness after eating (30.0 per cent), tiredness (28.7 per cent), and heartburn/acid or bile regurgitation (19.6 per cent). Clustering analysis showed that symptoms clustered into six domains: lethargy, musculoskeletal pain, dumping, lower gastrointestinal symptoms, regurgitation/reflux, and swallowing/conduit problems; the latter two were the most closely associated. Surgical approach, neoadjuvant therapy, patient age, and sex were factors associated with severe symptoms. CONCLUSION A long-term symptom burden is common after oesophageal cancer surgery.

Abstract
Pollen grains are the male gametophytes in a seed-plant life cycle. Their small, particulate nature and crucial role in plant reproduction have made them an attractive object of study using flow cytometry (FCM), with a wide range of applications existing in the literature. While methodological considerations for many of these overlap with those for other tissue types (e.g., general considerations for the measurement of nuclear DNA content), the relative complexity of pollen compared to single cells presents some unique challenges. We consider these here in the context of both the identification and isolation of pollen and its subunits, and the types of research applications. While the discussion here mostly concerns pollen, the general principles described here can be extended to apply to spores in ferns, lycophytes, and bryophytes. In addition to recommendations provided in more general studies, some recurring and notable issues related specifically to pollen and spores are highlighted.

Abstract
AbstractSchool classrooms within the EU are multilingual learning environments. The diversity of pupils in classrooms raises significant challenges for teachers, but to date, there are no data from large-scale surveys that compare views within and across European countries. A bespoke questionnaire was designed to examine views of current classroom learning environments with respect to the multilingualism. The questionnaire was piloted and subsequently completed by 2792 teachers across different European countries. Eleven countries provided sufficient data for analyses. Results from structural equation modelling showed that teachers’ attitudes could be reliably measured across Europe with the use of carefully devised questionnaire, whose loading and factor structure remained invariant across countries. Teachers’ views about multilingualism were most challenged by the numbers of children in their classes, not the percentage of multilingual pupils in the class. Countries differed in how they perceived multilingualism, with their differences leading to distinctive country clusters. Gender and education level (elementary vs. secondary) differences were also observed irrespective of country. These findings enhance our understanding of the role that the characteristics of teachers and their classrooms play in a multilingual setting across diverse European settings. The practical relevance of the results and new opportunities for teacher training are discussed.

Abstract
Even though plants represent an essential part of our lives offering exploitational, supporting and cultural services, we know very little about the biology of the rarest and most threatened plant species, and even less about their conservation status. Rapid changes in the environment and climate, today more pronounced than ever, affect their fitness and distribution causing rapid species declines, sometimes even before they had been discovered. Despite the high goals set by conservationists to protect native plants from further degradation and extinction, the initiatives for the conservation of threatened species in Europe are scattered and have not yielded the desired results. The main aim of this Action is to improve plant conservation in Europe through the establishment of a network of scientists and other stakeholders who deal with different aspects of plant conservation, from plant taxonomy, ecology, conservation genetics, conservation physiology and reproductive biology to protected area's managers, not forgetting social scientists, who are crucial when dealing with the general public.

Abstract
Abstract
Background
Patients with idiopathic outflow tract ventricular arrhythmias (OTVAs) and structurally normal heart by ECG and echocardiogram often undergo cardiac magnetic resonance (CMR) study to evaluate for presence of concealed myocardial abnormalities with late gadolinium enhancement (LGE). However, the clinical impact of incidental LGE finding in the left ventricle (LV) in patients with idiopathic OT-VAs is unclear. Accordingly, the aim of the present study was to investigate the prevalence, characteristics and prognostic significance of isolated LV LGE in a large population of patients with OTVA undergoing CMR.
Methods
A total of 364 consecutive patients (43±16 years, 53% male) with OTVA and negative routine diagnostic work-up were included. All patients underwent a CMR study with LGE imaging for detection of scar/replacement fibrosis. Presence of LGE was correlated with long term major adverse cardiovascular events including sudden cardiac death (SCD), resuscitated cardiac arrest and nonfatal documented sustained ventricular tachycardia.
Results
Isolated LGE in the LV was identified in 15 patients (4%), typically involving the inferolateral wall (11 cases, 73%) and having a median extension of 3 (2–5)% of the LV mass. All cases showed a midmyocardial/subepicardial distribution consistent with a possible prior myocarditis. Patients with incidental finding of LV-LGE were older (55±13 years vs. 42±16 years; p<0.01) and were more frequently males (80% vs. 51%; p=0.03). After a median follow-up of 69 (47–98) months, none of the patients in the LV-LGE group and 1 patient (0.3%) in the non-LGE group (p=1.0) experienced the composite end-point which consisted in an episode of sustained VT with hypotension and dizziness. The patient subsequently underwent effective radiofrequency ablation of the VT from the right ventricular outflow tract.
Conclusion
In this large CMR study, isolated LV scar was found in 4% of patients with idiopathic OT-VAs, was small in size with distribution consistent with prior myocarditis. The LGE abnormality did not portend a negative prognosis.

Abstract
Abstract
Background
The presence of left ventricular (LV) late gadolinium enhancement (LGE) at cardiac magnetic resonance (CMR) has been correlated to life-threatening arrhythmic events in patients with apparently idiopathic ventricular arrhythmias (VAs). Aim of the present study was to investigate the prognostic significance of a specific LV-LGE phenotype characterized by a subepicardial/midmyocardial “ring-like” pattern of fibrosis.
Methods
Out of a total of 518 consecutive patients with apparently idiopathic VAs who underwent CMR study, 79 (15%) had evidence of LV-LGE. Of these, 23 (4%) patients had LV LGE with ring-like pattern, defined as subepicardial or midmyocardial LGE involving at least 3 contiguous segments in the same slice (group A), while 56 (11%) patients had LV LGE with no ring-like pattern (group B). The remaining 439 patients had no LGE (group C). The end-point of the study was a composite SCD, resuscitated cardiac arrest and nonfatal episodes of ventricular fibrillation or documented sustained ventricular tachycardia.
Results
Group A patients were more frequently males compared to groups B and C (96% vs. 79% vs. 52%; p<0.01) and had more frequently a family history of SCD and/or cardiomyopathy (30% vs. 11% vs. 5%; p<0.01). All patients in Group A showed VAs with a predominant RBBB morphology vs. 38 (68%) patients in Group B and 65 (15%) in Group C (p<0.01). During a follow-up of 63±39 months, the composite outcome occurred in 13 patients (57%) in Group A vs. 11 (20%) in Group B and 2 (1%) in Group C (p<0.01).
Conclusion
In patients with apparently idiopathic VAs, a nonischemic LV-LGE with a ring-like pattern at CMR is associated with a high rate of malignant arrhythmic events during follow-up.

Abstract
BACKGROUND AND AIMS Polyploidy is an important contributor to sympatric speciation and assortative mating is a key mechanism driving cytotype interactions in contact zones. While strong reproductive barriers can mediate the coexistence of different cytotypes in sympatry, positive frequency-dependent mating disadvantage ultimately drives the transition to single-ploidy populations. However, comprehensive estimates of reproductive isolation among cytotypes and across multiple barriers are rare. We quantify the strength of isolation across multiple reproductive stages in a tetraploid-octoploid contact zone to understand the potential for coexistence. METHODS Assortative mating due to flowering asynchrony, pollinator behaviour, morphological overlap, self-fertilization and gametic competition between tetraploid and octoploid Gladiolus communis in a contact zone in the Western Iberian Peninsula were assessed in natural and experimental populations to quantify reproductive isolation (RI) between cytotypes. KEY RESULTS Tetraploids and octoploids have a high degree of overlap in flowering time and similar floral morphology, and are visited by generalist insects without cytotype foraging preferences, resulting in weak pre-pollination RI (from 0.00 to 0.21). In contrast, post-pollination isolation resulting from gametic selection was a strong barrier to inter-cytotype mating, with ploidy composition in stigmatic pollen loads determining the levels of RI (from 0.54 to 1.00). Between-cytotype cross-incompatibility was relatively high (RI from 0.54 to 0.63) as was isolation acquired through self-pollination (RI of 0.59 in tetraploids and 0.39 in octoploids). CONCLUSIONS Total RI was high for both tetraploids (from 0.90 to 1.00) and octoploids (from 0.78 to 0.98). Such high rates of assortative mating will enable cytotype coexistence in mixed-ploidy populations by weakening the impacts of minority cytotype exclusion. This study reveals the key role of gametic selection in cytotype siring success and highlights the importance of comprehensive estimates across multiple reproductive barriers to understand cytotype interactions at contact zones.

Abstract
Background:Interstitial Lung Disease (ILD) is an extra-articular complication of rheumatoid arthritis (RA) that is associated with increased morbidity and mortality. Conventional disease-modifying drugs (DMARDs) such as methotrexate (MTX) have been implicated in the development and exacerbation of a pre-existing ILD.Objectives:The aim of our study was to check the influence of combined MTX treatment in patients with RA-ILD treated with abatacept (ABA).Methods:National multicentre retrospective registry of 263 patients with RA-ILD treated with ABA. RA was diagnosed according to the ACR classification criteria of 1987 or by the EULAR/ACR criteria of 2010. ILD was diagnosed by high resolution computed tomography (HRCT). In this study we have done a subanalysis of the 46 patients treated with ABA in combination with MTX (ABA+MTX) vs. 217 patients treated with ABA in monotherapy or in combination with other synthetic DMARDs. Efficacy was evaluated according to the following parameters: a) Dyspnoea (MMRC) considering variations ≥ 1; b) Lung function test (LFT) considering variations ≥ 10% in FVC and a variation of DLCO ≥ 10%; c) Imaging test (HRCT) d) DAS28 score e) prednisone dose. Variables were collected at the beginning of the study and at months 3, 6, 12 and then every 12 months until a maximum of 60 months.Results:263 patients with ILD associated with RA were included in the study with mean age 64.64±10 years. RF or CCPA were positive in 235 (89.4%) and 233 (88.6%) cases, respectively, with a mean follow-up of 22.7±19.7 months. Baseline characteristics of both groups are shown in table 1, while data obtained during evolution of this complication are presented in Figure 1.Conclusion:Despite the baseline differences of both groups, the good evolution in the ABA+MTX subgroup suggests that this therapeutic strategy can be a safe combination for patients with RA-ILD.ABA with MTX (n=46)ABA w/t MTX (n=217)PSex (F/M)28/18122/950.625Age (years)65.11±10.216.2±9.80.202RF/CCPA + (%)91.3/91.389.8/90.10.810Smoking or past smoking (%)47.855.10.417Follow-up (months)22.73±18.0022.3±20.850.916DAS28 at baseline4.08±1.514.61±1.470.056DAS28 at last visit3.00±1.463.13±1.310.642Prednisone at baseline, median (IQR) (mg)5 (5-7.5)7.75 (5-15)0.008*Prednisone at the end of study, median (IQR) (mg)5 (1-5)5 (5-7.5)0.032*DLCO at baseline (%)66.85±19.0465.43±18.210.823DLCO at the end of study (%)66.05±20.9565.17±19.720.831FVC at baseline (%)90.06±17.7785.40±21.560.164FVC at the end of study (%)90.58±15,4584.21±21.490.038*Disclosure of Interests:Carlos Fernández-Díaz Speakers bureau: Brystol Meyers Squibb, Santos Castañeda: None declared, Rafael Melero: None declared, J.

Abstract
Background:Interstitial Lung Disease (ILD) is a severe extraarticular manifestation of rheumatoid arthritis (RA). In this line, several radiological patterns of RA-ILD have been described: i) usual interstitial pneumonia (UIP), ii) nonspecific interstitial pneumonia (NSIP), iii) obliterating bronchiolitis, iv) organized pneumonia and mixed patterns. Abatacept (ABA) could be an effective and safe option for patients with RA-ILD, although the response in the different radiological patterns is not well defined.Objectives:Our aim was to assess the response to ABA in different radiological patterns of ILD.Methods:Observational retrospective multicenter study of RA-ILD treated with ABA. ILD was diagnosed by HRCT and classified by radiological patterns in 3 different subgroups of RA-ILD: a) UIP, b) NSIP and c) “other”. ABA was used sc. or iv. at standard dose. We assessed: a) Dyspnoea (MMRC scale; significant variation ≥1); b) Respiratory function tests (significant changes ≥10% in FVC and DLCO); c) HRCT imaging; d) DAS28 e)prednisone dose.Variables were collected at months 0, 3, 6, 12 months and subsequently every 12 months until a maximum of 60 months.Results:We included 263 patients: 106 UIP, 84 NSIP and 73 others (150 women / 113 men), mean age 64.64±10 years. Total patients positive for RF or CCPA were 235 (89.4%) and 233 (88.6%), respectively. In 26 out of 263 patients, the development of ILD was closely related to the administration of sDMARDs (MTX n = 11 and LFN n = 1) or bDMARDs (ETN n = 5, ADA n = 4, CZP n = 2 and IFX n = 3). Patient characteristics are shown in table 1. Figure 1 shows the evolution of the cases with available data after a mean follow-up of 22.7±19.7 months. Mean DLCO and FVC remained stable in the 3 groups without statistically significant changes, and all the groups showed a statistically significant reduction in DAS28 and prednisone dose.Conclusion:ABA could be a good choice of treatment in patients with RA-ILD independently of the radiological pattern of ILD.Disclosure of Interests:Carlos Fernández-Díaz Speakers bureau: Brystol Meyers Squibb, Santos Castañeda: None declared, Rafael Melero: None declared, J.

Abstract
Background:Interstitial Lung Disease (ILD) is a severe complication of Rheumatoid Arthritis (RA). Several conventional disease-modifying anti-rheumatic drugs (cDMARDs) and biologic (b) DMARDs may induce or impaired ILD-RA. Abatacept (ABA) may be useful in ILD-RA (1).Objectives:To assess the efficacy and safety of ABA in a large series of ILD-RA for a long-term follow-up.Methods:Multicenter open-level study of ILD-RA treated with at least 1 dose of ABA. ILD was diagnosed by high-resolution computed tomography (HRTC). We study these outcomes: a) 1-point change Modied Medical Research Council (MMRC); b) forced vital capacity (FVC) and/or DLCO improvement or decline ≥10%; c) change in HRCT, d) change in DAS28. e) Prednisone dose. Values were collected at 0, 3, 6, 12 and then every 12 months.Results:We studied 263 patients (150 women/113 men) (mean age;64.6±10 years), with ILD-RA. At ABA-onset they were smokers or exsmoker (53.8%), positive APCC (88.6%), median [IQR] duration of ILD of 12 [3-41.25] months, mean DLCO (65.7±18.3) and FVC (85.9±21.8).The ILD-pattern were usual interstitial pneumonia (UIP) (40.3%), non-specific interstitial pneumonia (NSIP) (31.9%) and others (27.8%).ABA was prescribed at standard subcutaneous (125 mg/w) in 196 (74.5%) or intravenously (10 mg/kg/4 w) in 67 (25.5%); in monotherapy (n=111) or combined with cDMARDs (n=152); especially leflunomide (n=55), MTX (n=46), or antimarials (n=21).After a mean follow-up of 22.7±19.7 months most outcomes remain stable (Figure). Moreover, DAS28 improved from 4.5±1.5 to 3.1±1.3; prednisone dose reduced from a median 7.5 [5-10] to 5 mg [5-7.5] and retention rate was 76.4%. The main adverse effects were serious infections (n=28), neoplasia (n=3), serious infusion reaction (n=1) and myocardial infarction (n=1).Conclusion:ABA seems effective and relatively safe in ILD-RA.References:[1]Fernández-Díaz C et al.

Abstract
Polyploidization is a widespread mechanism of evolutionary divergence in flowering plants. Ecological divergence of polyploid lineages has been proposed as a key process shaping the distribution of cytotypes in nature (niche shift hypothesis); however, evidence for the role of niche separation in replicated diploid-polyploid species pairs is still needed. This study aimed to assess the role of abiotic factors shaping current cytotype distributions. For that, we examined the distribution and environmental niches of two varieties recognized in diploid-tetraploid Jasione maritima across the species range and within a putative contact zone on the Iberian Peninsula. We counted chromosomes, screened for ploidy across Iberian Peninsula and characterized environmental requirements using niche modeling tools. We found that J. maritima var. maritima is composed by diploids with disjunct distribution in the west coast of France and northwest Iberian Peninsula, and by tetraploids in Iberian Peninsula, while var. sabularia is tetraploid. In the Iberian Peninsula, two parapatric contact zones along a linear coastal distribution were detected, one between diploid and tetraploid var. maritima, and the other between tetraploids of the two varieties. Environmental variables of diploid populations from France are distinct from those of southern diploid populations, which are more similar to tetraploids. In general, niche modeling results are congruent with the observed distribution patterns, although the results suggest a wider contact zone between varieties and cytotypes. Tetraploids of both varieties revealed different degrees of environmental divergence in comparison with their diploid counterpart. Tetraploid var. sabularia differed environmentally from diploids suggesting niche divergence. In contrast, tetraploid var. maritima overlapped with diploid environmental niche and currently occupies its entire predicted range, whereas diploids are restricted to northern areas of their suitable environment. Differences in ecological envelopes facilitate the recognition of functional units of biodiversity within polyploid groups, allowing the study of factors related to post-polyploidization divergence. Thus, whereas changes in environmental requirements may have allowed tetraploid var. sabularia to spread in habitats not favorable to diploids, other factors are involved with the distribution of diploid and tetraploid var. maritima.

Abstract
BACKGROUND AND AIMS The distribution of cytotypes and its potential correlation with environmental variables represent a cornerstone to understanding the origin and maintenance of polyploid lineages. Although many studies have addressed this question in single species at a regional scale, only a few have attempted to decipher this enigma in groups of closely related species at a broad intercontinental geographical scale. Here, we consider approx. 20 species of a diploid-polyploid complex (Veronica subsect. Pentasepalae) of recent and rapid diversification represented in Europe and North Africa to study the frequency and distribution of cytotypes and their relationship to environmental variables. METHODS A total of 680 individuals (207 populations) were sampled. Ploidy levels were determined using flow cytometry. Ecological differentiation among cytotypes was tested using climatic and environmental variables related to temperature, precipitation, vegetation and biogeographical region, among others, and by performing univariate and multivariate (constrained principal coordinates analysis) analyses. KEY RESULTS Four ploidy levels (2x, 4x, 6x and 8x) were found and genome downsizing was observed to occur within the group. Plants of different ploidy level are ecologically differentiated, with hexaploids and octoploids occurring in wetter and colder habitats with a higher seasonality than diploids. A south to north distribution pattern was found, with diploids occupying southern refugial areas and octoploids being more frequent in northern regions of Europe above the permafrost boundary. CONCLUSIONS The distribution of cytotypes can be explained by ecological differentiation, the geographical position of refuge areas during the Quaternary climatic oscillations as well as by ice and permafrost retreat patterns. The Balkan Peninsula constitutes the most important contact zone between cytotypes. This work provides the first comprehensive ploidy screening within V. subsect. Pentasepalae at a broad scale and indicates that polyploidy and genome downsizing might have contributed to the colonization of new habitats in a recently diverged polyploid complex.

Abstract
PREMISE Newly formed polyploids face significant obstacles to persistence and population establishment because of fitness costs of intercytotype mating. Selfing provides the opportunity to escape mate limitation, enabling production of new individuals and increasing the likelihood of fixation of new polyploid lineages. Still, association between self-compatibility and polyploidy is not always clear. We compared self-incompatibility and inbreeding depression in neotetraploids and their diploid progenitor to explore the direct effects of whole genome duplications on self-incompatibility and the implications of ploidy-driven changes for polyploid establishment. METHODS Outcross and self-pollinations were performed in diploids and synthetic neotetraploids of Jasione maritima var. maritima, and reproductive success was measured through fruit and seed production and seed germination. Self- and outcross offspring were grown under controlled conditions, and plant performance was measured through several fitness parameters. RESULTS Neotetraploids showed an overall lower performance than diploids. Reproductive success was negatively affected by selfing in both cytotypes. However, greater variation in the expression of self-incompatibility was observed in neotetraploids; additionally, developmental and physiological parameters were not affected by selfing on neotetraploids, with an overall similar fitness of outcrossed and selfed individuals, resulting in lower inbreeding depression indexes. CONCLUSIONS Neotetraploids might have benefited from selfing at initial stages after their formation. Genome duplications resulted in leaky self-incompatibility, enabling the production of offspring under minority cytotype disadvantage with similar fitness as outcrossed offspring. Our results support theoretical assumptions that selfing might be important for neopolyploid establishment, although changes in self-incompatibility might not be abrupt.

Abstract
Despite the ongoing severe mismatch between organ need and supply, data from 2018 revealed some promising trends. For the fourth year in a row, the number of patients waiting for a kidney transplant in the US declined and numbers of both deceased and living donor kidney transplants increased. These encouraging trends are tempered by ongoing challenges, such as a large proportion of listed patients with dialysis time longer than 5 years. The proportion of candidates aged 65 years or older continued to rise, and the proportion undergoing transplant within 5 years of listing continued to vary dramatically nationwide, from 10% to nearly 80% across donation service areas. Increasing trends in the recovery of organs from hepatitis C positive donors and donors with anoxic brain injury warrant ongoing monitoring, as does the ongoing discard of nearly 20% of recovered organs. While the number of living donor transplants increased, racial disparities persisted in the proportion of living versus deceased donors. Strikingly, the total number of kidney transplant recipients alive with a functioning graft is on track to pass 250,000 in the next 1-2 years. The total number of pediatric kidney transplants remained steady at 756 in 2018. Deeply concerning to the pediatric community is the persistently low level of living donor kidney transplants, representing only 36.2% in 2018.

Abstract
BACKGROUND AND PURPOSE Perioperative chemotherapy (periCTX) based on the "MAGIC" scheme has become a standard treatment in Europe for locally advanced oesophagogastric cancer. We assessed implementation and long-term oncological outcomes of MAGIC periCTX for locally advanced gastric cancer. METHODS Population-based cohort study of all patients with locally advanced gastric cancer undergoing surgical resection with curative intent in Catalonia and Navarra (the first two autonomous communities included in the EURECCA Upper GI Spanish Working Group) between January 2011 and December 2013. The main variable was the percentage of patients treated with MAGIC periCTX. Kaplan-Meier analysis and Cox proportional hazards model were used to assess the survival benefit of periCTX. RESULTS Among 814 patients, 217 (26.6%) received periCTX (especially patients more likely to receive it: aged < 70 years, with proximal tumors, low anesthetic risk, and cT3-4/cN+ clinical stage). 35% did not complete perioperative chemotherapy, with no relationship with age. PeriCTX showed no effect on postoperative morbimortality. Histological tumor regression was more often absent or poor (38.2%) than total or almost total (27.8%), although clinico-pathological lymph-node downstaging was higher than expected by staging inaccuracy (38.7% vs. 24.2%). PeriCTX was associated with a better survival only in cT3-4 and cN+ patients, showing less prognostic relevance than optimal oncological surgery with D2 lymphadenectomy. CONCLUSIONS Only 26.6% of locally advanced resectable gastric cancer patients received PeriCTX. Pathological response was poor, although some degree of nodal downstaging was observed. Survival benefit of periCTX was limited to cT3-4 and cN+ patients, being less relevant than D2 lymphadenectomy.
