Building nations in the XXI century. Celticism, Nationalism and Archaeology in northern Spain: the case of Asturias and León

This investigation presents an overview of ‘Celtic’ nationalism in northern Spain, with the regions of Asturias and León as case studies. In these areas, archaeological narratives have served and still serve to justify contemporary political agendas. Archaeologists have thus become major actors in the discursive struggles over the past. However, they have become rather naïve and innocent regarding their contemporary public roles and their relationship towards social and political agendas. This situation has led to a lack of control over the use of their own narratives, which take on a life of their own in the public sphere. Our paper illustrates how archaeology has been used in the construction of contemporary political identities by regionalist and nationalist agents. Whereas nowadays Asturias aims to reinforce selfgovernment, the objective of León is to become a separate ‘Autonomous Community’ endowed with a certain degree of self-government separated from Castile

Iron Age Archaeology and Celticism as resource for the construction of contemporary identities in Asturias and León

El nacimiento de la Arqueología tiene una estrecha relación con el auge de los nacionalismos en toda Europa. En el estado español, tanto el nacionalismo centralista como los nacionalismos o regionalismos periféricos han utilizado referentes del pasado –a veces coincidentes– como sustento simbólico de sus narrativas. Es el caso de los celtas, pueblo mítico que ha servido tanto para afianzar la idea unitaria de España, como para refrendar la singularidad nacional/regional de territorios como Asturias y León. El papel de los arqueólogos en estos dos casos es analizado en este trabajo, pues supone una vía crucial para la reflexión historiográfica. Así, las narrativas académicas generadas en este ámbito adolecían habitualmente de una falta de crítica, que subordinaba el pasado prerromano a determinadas agendas políticas contemporáneas. La predominancia de la Historia Antigua o de visiones esencialistas, androcéntricas y socialmente conservadoras en los discursos arqueológicos caracterizan los estudios tradicionales sobre los grupos prerromanos de Asturias y León. Tras la consolidación del Estado de las Autonomías, el nacionalismo y el regionalismo se extendieron a amplias capas de la sociedad acompañados de discursos históricos que prescindieron de la legitimación de la Academia. Paradójicamente, estas narrativas reproducen discursos conservadores que tradicionalmente dominaban el discurso arqueológico. Ante esta situación, ¿nos corresponde a los arqueólogos asumir una posición multivocal liberal o deberíamos, en cambio, emprender acciones sociopolíticas críticas que inicien una autocrítica disciplinar y persigan transformar los marcos teórico-interpretativos dominantes?.The origins of archaeology are intrinsically connected with the emergence of nationalism in Europe. Both Spanish centralist nationalism and peripheral nationalism and regionalist movements in the country are engaged in a political dispute but, paradoxically, have drawn upon similar symbolic resources in some cases. This is true regarding historic construct of the Celts in Asturias and León, where different political movements, either peripheral or centralist, have differently interpreted and used the Celts in their agendas depending on the historic context. This paper analyzes the role archaeologists have played in this process. Acritical discourses have prevailed in Iron Age Archaeology, which has always made the past subservient to contemporary political needs. In addition, Iron Age Archaeology has strongly relied on the disciplinary bias of Ancient History, and has been dominated by essentialist, androcentric and largely reactionary interpretations of society. With the advent of the Autonomous Communities in Spain, nationalism and regionalism permeated vast sectors of Spanish society, leading to the emergence of many popular discourses about the past that disregard Academic discourse. Paradoxically, these narratives reproduce conservative discourses that prevailed in archaeological research. Facing this situation, it is time for archaeologists to ask whether they should adopt a multivocal liberal stance tolerating different interpretations about the past, or a critical socio-political position seeking a deconstruction of the discipline and a transformation of the dominant interpretative frameworks that predate Spanish Archaeology.Depto. de Prehistoria, Historia Antigua y ArqueologíaFac. de Geografía e HistoriaTRUEpu

Functional polymorphisms in the CYP3A4, CYP3A5, and CYP21A2 genes in the risk for hypertension in pregnancy

An intronic single nucleotide polymorphism (SNP) in the CYP3A5 gene (CYP3A5*3; SNP rs776746) affects RNA splicing and enzymatic activity. The CYP3A5*3 frequency increased with distance from the equator and natural selection has been proposed to explain the worldwide distribution of this allele. CYP3A activity has been related with the risk for hypertension in pregnancy, a major cause of morbidity and mortality among women, and CYP3A5*3 could reduce the risk for this disease in populations from regions with high sodium and water availability. The CYP3A5 genotype was related with blood pressure in the general population, but the effect on the risk for hypertension in pregnancy has not been evaluated. We compared the allele and genotype frequencies of three functional SNPs in the CYP3A5 (rs776746), CYP3A4 (rs2740574), and CYP21A2 (rs6471) genes between pregnant women who developed hypertension (n=250) or who remained normotensive (control group, n=250). In addition, we sequenced the full CYP3A5 coding sequence in 40 women from the two groups to determine whether some gene variants could explain the risk for hypertensive pregnancies in our population. Allele and genotype frequencies did not differ between hypertensive and normotensive women for the three CYP variants. We did not find CYP3A5 nucleotide changes that could explain a higher risk for hypertension in pregnancy. Our data suggests that the variation in CYP3A5, CYP3A4, and CYP21A2 did not contribute to the risk for hypertension in pregnancy in our populationThe author´s work is supported by a grant from the Spanish Fondo de Investigaciones Sanitarias/Fondos FEDER European Union (ETS PI08/90008)

Prediction of poor outcome in clostridioides difficile infection: A multicentre external validation of the toxin B amplification cycle

Producción CientíficaClassification of patients according to their risk of poor outcomes in Clostridioides difficile infection (CDI) would enable implementation of costly new treatment options in a subset of patients at higher risk of poor outcome. In a previous study, we found that low toxin B amplification cycle thresholds (Ct) were independently associated with poor outcome CDI. Our objective was to perform a multicentre external validation of a PCR-toxin B Ct as a marker of poor outcome CDI. We carried out a multicentre study (14 hospitals) in which the characteristics and outcome of patients with CDI were evaluated. A subanalysis of the results of the amplification curve of real-time PCR gene toxin B (XpertTM C. difficile) was performed. A total of 223 patients were included. The median age was 73.0 years, 50.2% were female, and the median Charlson index was 3.0. The comparison of poor outcome and non–poor outcome CDI episodes revealed, respectively, the following results: median age (years), 77.0 vs 72.0 (p = 0.009); patients from nursing homes, 24.4% vs 10.8% (p = 0.039); median leukocytes (cells/μl), 10,740.0 vs 8795.0 (p = 0.026); and median PCR-toxin B Ct, 23.3 vs 25.4 (p = 0.004). Multivariate analysis showed that a PCR-toxin B Ct cut-off <23.5 was significantly and independently associated with poor outcome CDI (p = 0.002; OR, 3.371; 95%CI, 1.565–7.264). This variable correctly classified 68.5% of patients. The use of this microbiological marker could facilitate early selection of patients who are at higher risk of poor outcome and are more likely to benefit from newer and more costly therapeutic options

Echocardiographic Changes with Positive Airway Pressure Therapy in Obesity Hypoventilation Syndrome. Long-Term Pickwick Randomized Controlled Clinical Trial

Spanish Sleep Network.[Rationale] Obesity hypoventilation syndrome (OHS) has been associated with cardiac dysfunction. However, randomized trials assessing the impact of long-term noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP) on cardiac structure and function assessed by echocardiography are lacking. Rationale: Obesity hypoventilation syndrome (OHS) has been associated with cardiac dysfunction. However, randomized trials assessing the impact of long-term noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP) on cardiac structure and function assessed by echocardiography are lacking.[Objectives] In a prespecified secondary analysis of the largest multicenter randomized controlled trial of OHS (Pickwick Project; N = 221 patients with OHS and coexistent severe obstructive sleep apnea), we compared the effectiveness of three years of NIV and CPAP on structural and functional echocardiographic changes.[Methods] At baseline and annually during three sequential years, patients underwent transthoracic two-dimensional and Doppler echocardiography. Echocardiographers at each site were blinded to the treatment allocation. Statistical analysis was performed using a linear mixed-effects model with a treatment group and repeated measures interaction to determine the differential effect between CPAP and NIV. Measurements and Main Results: A total of 196 patients were analyzed: 102 were treated with CPAP and 94 were treated with NIV. Systolic pulmonary artery pressure decreased from 40.5 ± 1.47 mm Hg at baseline to 35.3 ± 1.33 mm Hg at three years with CPAP, and from 41.5 ± 1.56 mm Hg to 35.5 ± 1.42 with NIV (P < 0.0001 for longitudinal intragroup changes for both treatment arms). However, there were no significant differences between groups. NIV and CPAP therapies similarly improved left ventricular diastolic dysfunction and reduced left atrial diameter. Both NIV and CPAP improved respiratory function and dyspnea.[Conclusions] In patients with OHS who have concomitant severe obstructive sleep apnea, long-term treatment with NIV and CPAP led to similar degrees of improvement in pulmonary hypertension and left ventricular diastolic dysfunction

Inter-Rater Variability in the Evaluation of Lung Ultrasound in Videos Acquired from COVID-19 Patients

12 páginas, 7 figuras, 1 tablaLung ultrasound (LUS) allows for the detection of a series of manifestations of COVID-19, such as B-lines and consolidations. The objective of this work was to study the inter-rater reliability (IRR) when detecting signs associated with COVID-19 in the LUS, as well as the performance of the test in a longitudinal or transverse orientation. Thirty-three physicians with advanced experience in LUS independently evaluated ultrasound videos previously acquired using the ULTRACOV system on 20 patients with confirmed COVID-19. For each patient, 24 videos of 3 s were acquired (using 12 positions with the probe in longitudinal and transverse orientations). The physicians had no information about the patients or other previous evaluations. The score assigned to each acquisition followed the convention applied in previous studies. A substantial IRR was found in the cases of normal LUS (κ = 0.74), with only a fair IRR for the presence of individual B-lines (κ = 0.36) and for confluent B-lines occupying 50% (κ = 0.50). No statistically significant differences between the longitudinal and transverse scans were found. The IRR for LUS of COVID-19 patients may benefit from more standardized clinical protocols.This research was partially funded by CDTI (Spanish acronym: Centre for Industrial Tech- nological Development), funding number COI-20201153.

Predictors of Response to Exclusive Enteral Nutrition in Newly Diagnosed Crohn´s Disease in Children: PRESENCE Study from SEGHNP

Exclusive enteral nutrition (EEN) has been shown to be more effective than corticosteroids in achieving mucosal healing in children with Crohn´s disease (CD) without the adverse effects of these drugs. The aims of this study were to determine the efficacy of EEN in terms of inducing clinical remission in children newly diagnosed with CD, to describe the predictive factors of response to EEN and the need for treatment with biological agents during the first 12 months of the disease. We conducted an observational retrospective multicentre study that included paediatric patients newly diagnosed with CD between 2014–2016 who underwent EEN. Two hundred and twenty-two patients (140 males) from 35 paediatric centres were included, with a mean age at diagnosis of 11.6 ± 2.5 years. The median EEN duration was 8 weeks (IQR 6.6–8.5), and 184 of the patients (83%) achieved clinical remission (weighted paediatric Crohn’s Disease activity index [wPCDAI] 15 mg/L and ileal involvement tended to respond better to EEN. EEN administered for 6–8 weeks is effective for inducing clinical remission. Due to the high response rate in our series, EEN should be used as the first-line therapy in luminal paediatric Crohn’s disease regardless of the location of disease and disease activityS

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio
