We present a parton-level study of electro-weak production of vector-boson pairs at the Large Hadron Collider, establishing the sensitivity to a set of dimension-six operators in the ...Standard Model Effective Field Theory (SMEFT). Different final states are statistically combined, and we discuss how the orthogonality and interdependence of different analyses must be considered to obtain the most stringent constraints. The main novelties of our study are the inclusion of SMEFT effects in non-resonant diagrams and in irreducible QCD backgrounds, and an exhaustive template analysis of optimal observables for each operator and process considered. We also assess for the first time the sensitivity of vector-boson-scattering searches in semileptonic final states.
The aim of our study was to evaluate the usefulness and applicability of sentinel lymph node (SLN) identification in N0 carcinomas of the oral cavity and oropharynx.
We carried out a prospective ...evaluation of SLN identification in 20 patients with oral cavity or oropharynx carcinomas with no clinical evidence of lymph node metastases.
Peritumoral infiltration with technetium-99-labeled nanocolloid followed by lymphoscintigraphy was carried out approximately 18 hours prior to surgery. A vital dye was injected intraoperatively and the SLN was identified with the aid of a gamma probe. All patients underwent routine neck dissection.
While multiple radioactive nodes were generally identified on lymphoscintigraphy, the number of nodes ranging from one to five with variable degrees of uptake, intraoperative gamma probe scanning allowed the identification of a single more radioactive lymph node in 19 of the 20 patients. In only one patient did this method lead to the identification of two equally highly radioactive SLNs, with no uptake in the remaining nodes. All SLNs were ipsilateral to the neoplastic lesion. In 15 cases the SLN was tumor negative and so were the remaining nodes obtained by comprehensive neck dissection. In five cases the SLN was the only lymph node containing micrometastasis among those obtained by dissection. There were no instances of node positivity not involving the SLN.
Sentinel lymph node identification in ENT surgery may indicate intraoperatively if node metastasis are present, thereby avoiding overtreatment in a substantial proportion of patients with N0 carcinomas of the oral cavity or oropharynx.
Metastable deexcitation spectroscopy (MDS) was applied to the study of the electronic structure of Sb/GaAs (110) and H:GaAs(110) systems. For both systems valuable insights into the surface ...electronic structure (effective surface density of states and surface charge density) were obtained. A surface to volume ratio extremely higher than photoemission was obtained for MDS. For both systems new features, never observed by more conventional surface spectroscopies, were detected.
The efficacy of anticoagulant treatment in the prevention of thromboembolic complications among patients with nonrheumatic atrial fibrillation is established. In our country, data on the use of this ...therapy in clinical practice are not available.
To examine anticoagulants use among patients with nonrheumatic atrial fibrillation and to analyze the influence of several thromboembolic risk factors in anticoagulant use.
We have studied, 302 patients retrospectively, with nonrheumatic atrial fibrillation. We determined the presence of heart failure, hypertension, previous thromboembolism, diabetes and left atrium dilation. We added age, sex, pattern of non-permanent arrhythmia and hospitalization and we conducted univariate and multivariate analyses to identify their influence the establishment of the anticoagulant treatment.
28.8% of patients were treated with oral anticoagulants, 83.7% were treated with oral anticoagulant or antiplatelet agents. Only three patients, out of 49, aged 80 years or older were treated with anticoagulants. Multivariate analysis showed that previous thromboembolism (odds ratio 4.03 1.9-8.1), permanent atrial fibrillation (odds ratio 2.6 1.3-5.3), left atrium dilation (odds ratio 2.3 1.2-4.1) and heart failure (odds ratio 1.9 1.07-3.6) were factors that predicted higher use of anticoagulant treatment.
a) Anticoagulant treatment is underused among patients with nonrheumatic atrial fibrillation; b) previous thromboembolism, left atrium dilation and heart failure have conditioned higher probability of undergoing anticoagulant treatment, and c) patients aged 80 years and over and non permanent atrial fibrillation predicted less use of the therapy.

Anticoagulant therapy has shown its efficacy in the prevention of thromboembolic complications but it is not devoid of bleeding complications. Although the thromboembolic risk of some cardiac ...diseases may be extrapolated from well-organized clinical trials, the risk of bleeding complications should be determined in the context of the environment in which it is carried out.
To determine the complications of the patients in anticoagulant therapy, in our environment, and to analyse the of risk factors.
We have studied the complications suffered by 300 patients who underwent anticoagulation for cardiac diseases, between March-94 and March-96 retrospectively. We have classified the complications in two groups: a) Fatal or intracranial with sequelae. b) Those requiring hospitalization and/or transfusion. Univariate and multivariant analyses were conducted to identify predictors of complications, including the following factors: age, sex, diabetes, hypertension, length of therapy, distance from our Center to their place of residence, INR (> 3 vs 2 to 3) and number of drugs associated with Acenocoumarol (> or = 3 vs 2 or less).
During the follow-up 24 patients died due to non haemorrhagic complications; 3 left the treatment on their cardiologist recommendation; 2 moved their place of residence and 1 was lost in the follow-up. Of 270 remaining 3 (0.55/100 patients-year) had complications of group a and 21 (3.88/100 patients-year) of grub b. INR > 3 and multiple medications were shown as predictors of complications when including some of the complications considered.
1) During two years of follow-up 1.1% (0.55/100 patients-year) of patients in anticaogulant therapy had bleeding complications resulting in death or neurological sequelae. 2) When including some of the complications considered the percentage rises to 4.44/100 patients-years. 3) Although there were no differences statistically significant, INR > 3 and polymedication have been found as predictors risk factor. 4) Patients with INR of 2 to 3 and non polymedicated presented a low risk of bleeding complications (1.66/100 patients-year).
The health emergency generated by COVID-19 and the massive closure of schools has given rise to an unprecedented situation for education systems worldwide. This situation has raised fundamental ...questions about the role of the school in contemporary societies and whether it still fulfils a particular function as a social institution. This article forwards a theoretical discussion on these issues from a critical sociological approach and, especially, from the perspective of social justice. It argues that the two main functions of schools, namely, socialisation and selection, cannot be fully achieved by distance schooling. Moreover, it contends that the lockdown of schools reinforced the crisis of meaning within the school system by hindering its ability to ensure learning for all students. Overall, the article presents a reflection on the meaning of the school institution in the 21
st
century, representing a key contribution to contemporary debates on the sociology of education.
