Les importacions etrusques del segle V a.C. al nord-est peninsular i el comerç mediterrani

Afí d'ubicar geogràfica i històricament les importacions etrusques del segle V a.e. al nord-est peninsular, partim d'un estudi actualitzat deis objectes en si i de llur context arqueològic. Tot seguit, observem quina és la situació històrica a Etrúria, tenint en compte els esdeveniments interns i la seva política comercial. A través de l'anillisi de les influències púniques i gregues en les nostres terres, esbossem la situació interna de la societat ibèrica, receptora d'aquestes importacions mediterranies. És així com arribem a tenir una visió força completa de tot el procés que segueixen els diversos productes etruscs i com en podem treure conclusions tant pel que fa al context de fabricació i exportació com pe! que fa al moment d'arribada a la Península Iberica. _____________________________________________ Dans le but de situer geographiquement et historiquement les importations étrusques du Veme siecle ay. Je. du nord-est de la Péninsule Ibérique, nous proposons une étude mise a jour de ces différents objets ainsi que de leur contexte archéologique. Nous examinons ensuite quelle est la situation historique en Etrurie en tenant compte des évenements internes et de sa politique commerciale. A partir de l'analyse des influences puniques et grecques dans la zone étudiée, nous observons la situation interne de la société ibérique, réceptrice de ces importations méditerranéennes. Arrivés a ce point, nous disposons d'une vision assez large de tout le chemin suivit par les produits étrusques et nous sommes, donc, capables d' en tirer des conclusions sur leur contexte de fabrication et exportation mais aussi sur leur moment d'arrivée a la Péninsule Ibérique

Interrelació de les estructures comercials protohistòriques a l'àrea del Mediterrani Centre-Occidental: dos casos d'estudi: Etrúria i Iberia

Tesi de Llicenciatura per a la obtenció del Grau d'Història i Geografia. Universitat de Barcelona. Directora: Glòria Munilla Cabrillana. Setembre de 1995.El nostre estudi es basa fonamentalment en les importacions etrusques localitzades a Catalunya. Hem procurat fer-ne un inventari, el més complet i exhaustiu possible, a partir de les diferents publicicions i d'algun fragment inèdit procedent de les antigues excavacions de la Palaiàpolis emporitana. Tot i això, donada la relació de l'àrea de l'Ebre amb el Llevant peninsular i Eivissa, hem cregut igualment necessari d'incloure dins del nostre treball la problemàtica referent a aquestes dues àrees i les importacions etrusques que s'hi han localitzat, si més no, de manera representativa. Pel que fa al sud peninsular, durant aquests últims anys, hom ha realitzat nombrosos treballs on s'han posat al descobert noves troballes etrusques que fan replantejar-se la qüestió de les relacions comercials d'aquesta àrea amb el món etrusc. A causa de la complexitat i de la magnitud del tema, creiem que mereix ser tractat degudament en un estudi més específic. Per tant, nosaltres ens hem limitat a mencionar els trets més representatius del que s'esdevé en aquesta àrea i que mantenen alguna mena de relació directa el nord-est peninsular

Psychological factors and prognostic communication preferences in advanced cancer: multicentre study

Objectives: Communication regarding prognosis to patients with advanced cancer is fundamental for informed medical decision making. Our objective was to analyse (1) the proportion of subjects with advanced cancer who prefer to know their prognosis, (2) the characteristics associated with patients’ preference for prognostic information, (3) the psychological factors that impact the preference to know prognosis and 4) the concordance between preference for prognostic information perceived among physicians and patients. Methods: A prospective, cross-sectional design was adopted. Data were collected from 748 participants with advanced cancer at 15 tertiary hospitals in Spain. Participants completed the following questionnaires: Mental Adjustment to Cancer; Trust in the Physician; Uncertainty in Illness Scale Patient’s Prognostic Preferences. Results: Fifty-two per cent of advanced cancer sufferers preferred to know the prognosis of their disease. Compared with participants who preferred not to know, those who did reported more uncertainty, greater satisfaction with their physician and higher scores on positive attitude (all p=0.001). Thirty-seven per cent of the physicians believed that patients want to know their prognosis, indicating that they underestimate the number of such patients. No significant differences were found regarding preference to know prognosis as a function of sociodemographic and clinical variables. Conclusions: A substantial proportion of individuals with advanced cancer prefer to know the prognosis of their disease. It appears that knowing their prognosis was mainly motivated by a need to maintain a positive attitude, lessen uncertainty and by satisfaction with the physician. It is important to explore patients’ preferences for information to offer more personalised communication

A Multitrait Genetic Study of Hemostatic Factors and Hemorrhagic Transformation after Stroke Treatment

BACKGROUND: Thrombolytic recombinant tissue plasminogen activator (r-tPA) treatment is the only pharmacologic intervention available in the ischemic stroke acute phase. This treatment is associated with an increased risk of intracerebral hemorrhages, known as hemorrhagic transformations (HTs), which worsen the patient\u27s prognosis. OBJECTIVES: to investigate the association between genetically determined natural hemostatic factors\u27 levels and increased risk of HT after r-tPA treatment. METHODS: Using data from genome-wide association studies on the risk of HT after r-tPA treatment and data on 7 hemostatic factors (factor [F]VII, FVIII, von Willebrand factor [VWF], FXI, fibrinogen, plasminogen activator inhibitor-1, and tissue plasminogen activator), we performed local and global genetic correlation estimation multitrait analyses and colocalization and 2-sample Mendelian randomization analyses between hemostatic factors and HT. RESULTS: Local correlations identified a genomic region on chromosome 16 with shared covariance: fibrinogen-HT, P = 2.45 × 10 CONCLUSION: We identified 4 shared loci between hemostatic factors and HT after r-tPA treatment, suggesting common regulatory mechanisms between fibrinogen and VWF levels and HT. Further research to determine a possible mediating effect of fibrinogen on HT risk is needed

Documento de consenso de la Sociedad Española de Obstetricia y Ginecologia (SEGO) y el Comité Español Interdisciplinario para la Prevención Vascular (CEIPV). Ventana de oportunidad: prevención del riesgo vascular en la mujer. Resultados adversos del embarazo y riesgo de enfermedad vascular

Este documento resume la evidencia que existe entre los resultados adversos del embarazo (RAE), tales como son los trastornos hipertensivos, el parto pretérmino, la diabetes gestacional, los defectos en el crecimiento fetal (feto pequeño para la edad gestacional y/o restricción del crecimiento), el desprendimiento de placenta y la pérdida fetal, y el riesgo que tiene una persona gestante de desarrollar factores de riesgo vascular (RV) que pueden terminar provocando enfermedad vascular (EV) futura: cardiopatía coronaria, accidente cerebrovascular, enfermedad vascular periférica e insuficiencia cardíaca. Asimismo, este documento destaca la importancia de saber reconocer los RAE cuando se evalúa el RV en mujeres. Un antecedente de RAE es un indicador suficiente para hacer una prevención primaria de EV. De hecho, adoptar una dieta saludable y aumentar la actividad física entre las mujeres con RAE, de inicio en el embarazo y/o postparto y manteniéndolo a lo largo de la vida, son intervenciones importantes que permiten disminuir el RV. Por otro lado, la lactancia materna también puede disminuir el RV posterior de la mujer, incluyendo menos riesgo de mortalidad. Estudios futuros que evalúen el uso del ácido acetilsalicílico, las estatinas y la metformina, entre otros, en las mujeres con antecedentes de RAE podrían reforzar las recomendaciones sobre el uso de la farmacoterapia en la prevención primaria de la EV entre estas pacientes. Existen diferentes opciones dentro de los sistemas de salud para mejorar la transición de la atención de las mujeres con RAE entre los diferentes profesionales e implementar estrategias para reducir su RV a largo plazo. Una posible estrategia podría ser la incorporación del concepto del cuarto trimestre en las recomendaciones clínicas y las políticas de atención de la salud.This document summarises the evidence regarding the association between adverse pregnancy outcomes (APOs), such as hypertensive disorders, preterm birth, gestational diabetes, fetal growth defects (small for gestational age and/or fetal growth restriction), placental abruption, fetal loss, and the risk that a pregnant individual in developing vascular risk factors (VR) that may lead to future vascular disease (VD): coronary heart disease, stroke, peripheral vascular disease, and heart failure. Furthermore, this document emphasises the importance of recognising APOs when assessing VR in women. A history of APOs serves as a sufficient indicator for primary prevention of VD. In fact, adopting a healthy diet and increasing physical activity among women with APOs, starting during pregnancy and/or postpartum, and maintaining it throughout life are significant interventions that can reduce VR. On the other hand, breastfeeding can also reduce the future VR of women, including a lower risk of mortality. Future studies evaluating the use of aspirin, statins, and metformin, among others, in women with a history of APOs could strengthen recommendations regarding pharmacotherapy for primary prevention of VD in these patients. Various healthcare system options exist to improve the transition of care for women with APOs between different healthcare professionals and implement long-term VR reduction strategies. One potential process could involve incorporating the fourth-trimester concept into clinical recommendations and healthcare policies

A multitrait genetic study of hemostatic factors and hemorrhagic transformation after stroke treatment

[Background] Thrombolytic recombinant tissue plasminogen activator (r-tPA) treatment is the only pharmacologic intervention available in the ischemic stroke acute phase. This treatment is associated with an increased risk of intracerebral hemorrhages, known as hemorrhagic transformations (HTs), which worsen the patient’s prognosis.[Objectives] To investigate the association between genetically determined natural hemostatic factors’ levels and increased risk of HT after r-tPA treatment.[Methods] Using data from genome-wide association studies on the risk of HT after r-tPA treatment and data on 7 hemostatic factors (factor [F]VII, FVIII, von Willebrand factor [VWF], FXI, fibrinogen, plasminogen activator inhibitor-1, and tissue plasminogen activator), we performed local and global genetic correlation estimation multitrait analyses and colocalization and 2-sample Mendelian randomization analyses between hemostatic factors and HT.[Results] Local correlations identified a genomic region on chromosome 16 with shared covariance: fibrinogen-HT, P = 2.45 × 10−11. Multitrait analysis between fibrinogen-HT revealed 3 loci that simultaneously regulate circulating levels of fibrinogen and risk of HT: rs56026866 (PLXND1), P = 8.80 × 10−10; rs1421067 (CHD9), P = 1.81 × 10−14; and rs34780449, near ROBO1 gene, P = 1.64 × 10−8. Multitrait analysis between VWF-HT showed a novel common association regulating VWF and risk of HT after r-tPA at rs10942300 (ZNF366), P = 1.81 × 10−14. Mendelian randomization analysis did not find significant causal associations, although a nominal association was observed for FXI-HT (inverse-variance weighted estimate [SE], 0.07 [−0.29 to 0.00]; odds ratio, 0.87; 95% CI, 0.75-1.00; raw P = .05).[Conclusion] We identified 4 shared loci between hemostatic factors and HT after r-tPA treatment, suggesting common regulatory mechanisms between fibrinogen and VWF levels and HT. Further research to determine a possible mediating effect of fibrinogen on HT risk is needed.This study is supported in part by the National Heart, Lung, and Blood Institute grants HL134894, HL139553, and HL141291.

Systematic Collaborative Reanalysis of Genomic Data Improves Diagnostic Yield in Neurologic Rare Diseases

Altres ajuts: Generalitat de Catalunya, Departament de Salut; Generalitat de Catalunya, Departament d'Empresa i Coneixement i CERCA Program; Ministerio de Ciencia e Innovación; Instituto Nacional de Bioinformática; ELIXIR Implementation Studies (CNAG-CRG); Centro de Investigaciones Biomédicas en Red de Enfermedades Raras; Centro de Excelencia Severo Ochoa; European Regional Development Fund (FEDER).Many patients experiencing a rare disease remain undiagnosed even after genomic testing. Reanalysis of existing genomic data has shown to increase diagnostic yield, although there are few systematic and comprehensive reanalysis efforts that enable collaborative interpretation and future reinterpretation. The Undiagnosed Rare Disease Program of Catalonia project collated previously inconclusive good quality genomic data (panels, exomes, and genomes) and standardized phenotypic profiles from 323 families (543 individuals) with a neurologic rare disease. The data were reanalyzed systematically to identify relatedness, runs of homozygosity, consanguinity, single-nucleotide variants, insertions and deletions, and copy number variants. Data were shared and collaboratively interpreted within the consortium through a customized Genome-Phenome Analysis Platform, which also enables future data reinterpretation. Reanalysis of existing genomic data provided a diagnosis for 20.7% of the patients, including 1.8% diagnosed after the generation of additional genomic data to identify a second pathogenic heterozygous variant. Diagnostic rate was significantly higher for family-based exome/genome reanalysis compared with singleton panels. Most new diagnoses were attributable to recent gene-disease associations (50.8%), additional or improved bioinformatic analysis (19.7%), and standardized phenotyping data integrated within the Undiagnosed Rare Disease Program of Catalonia Genome-Phenome Analysis Platform functionalities (18%)

Moléculas inflamatorias y marcadores de lesión endotelial en la isquemia cerebral: participación en el deterioro neurológico y la transformación hemorrágica

Los mecanismos implicados en el deterioro neurológico precoz (DNP) y en la transformación hemorrágica (TH) de la lesión isquémica cerebral no se conocen con exactitud. Estudios previos habían demostrado la asociación de niveles elevados de TNF-a e IL-6 con el DNP en pacientes con isquemia cerebral independientemente del mecanismo ictal. Sin embargo, los mecanismos relacionados con el DNP en pacientes con infarto lacunar no se conocían con exactitud. Con el objetivo de determinar si los mecanismos inflamatorios participaban en la progresión y el pronóstico funcional de estos pacientes se determinaron los niveles de TNF-a, IL-6 e ICAM-1 en el momento del ingreso en 113 pacientes con ictus lacunar de 14 pg/mL y de ICAM-1 > 208 pg/mL se asociaban de manera independiente tanto con el DNP como con el mal pronóstico funcional evaluado a los 3 meses. En cuanto a la TH, se había demostrado la asociación de niveles elevados de MMP-9 y la aparición de TH exclusivamente en pacientes con ictus de mecanismo cardioembólico por lo que se analizaron los niveles de esta molécula en 250 pacientes con ictus hemisférico de 14 pg/mL and ICAM-1 > 208 pg/mL were independently associated with both END and poor outcome at 3 months. On the other hand, the association between high levels of matrix metaloproteinase-9 (MMP-9) and secondary bleeding in patients with cardiembolic ischemic stroke had been already published. However, there were no data about the HT predictive capacity of MMP-9 in patients with other stroke subtypes. The association between high levels of MMP-9 and the development of HT was determined in 250 patients with hemispheric ischemic stroke within the first 24 hours of symptoms' onset. The results demonstrated that those patients with HT had significantly higher levels of MMP-9 at admission compared to those without secondary bleeding. Logistic regression analysis showed that MMP-9 levels ≥ 140 ng/mL were independently associated with HT after adjustment for potential confounders. Moreover, MMP-9 levels ≥ 140 ng/mL predicted the development of HT with a sensitivity, especificity, negative predictive value (NPV) and positive predictive value (PPV) of 87%, 90%, 61% and 97%, respectively. Finally, the association between the levels of cellular-Fibronectin (c-Fn), taken as a more specific marker of endothelial damage, and the development of HT in 87 patients who received thrombolytic treatment with rt-PA was evaluated. In order to compare the predictive capacity of MMP-9 and c-Fn levels, the levels of MMP-9 were also analyzed in this group of patients. The results demonstrated that patients with HT had significantly higher c-Fn as well as MMP-9 levels before the administration of the treatment. The levels of c-Fn were also higher in patients with symptomatic HT whereas no differences were found in MMP-9 levels between symptomatic and asymptomatic HT. Logistic regression analysis showed that c-Fn levels was the only variable associated with HT development after adjustment of potential confounders, which included MMP-9 levels. Levels of c-Fn ≥ 3.6 µg/mL predicted the development of hemorrhagic infarction type 2 and parenchymal hemorrhage (types of HT that has been reported to occur more often in patients treated with rt-PA) with a sensitivity of 100%, specificity of 96%, NPV of 44% and PPV of 100%, whereas the sensitivity, specificity, NPV and PPV of MMP-9 levels ≥ 140 ng/mL were 81%, 88%, 41% and 98%, respectively. These results were observed both in patients treated within 6 hours and within 3 hours from symptoms' onset. In conclusion, the results suggest that inflammation contributes to brain injury in patients with lacunar stroke and confirm that high plasma MMP-9 concentration is an independent predictor of HT in patients with acute ischemic stroke. Moreover, high plasma c-Fn levels are significantly associated with subsequent HT in stroke patients treated with rt-PA, so plasma c-Fn determinations might be useful in clinical practice to improve the risk/benefit ratio of thrombolytic treatment

A predictive clinical-genetic model of tissue plasminogen activator response in acute ischemic stroke

Wide interindividual variability exists in response to tissue plasminogen activator (t-PA) treatment in the acute phase of ischemic stroke. We aimed to find genetic variations associated with hemorrhagic transformation (HT) and mortality rates after t-PA. We then generated a clinical-genetic model for predicting t-PA response
