Abstract	Background: The use of cervical drains to prevent cervical hematoma or seroma after thyroidectomy remains a controversial issue. Objective: Identify clinical and surgical risk factors for hematoma or seroma and evaluate the usefulness of routine use of drains following thyroid surgery. Material and methods: The authors conducted a retrospective multicentric study related to consecutive patients submitted to thyroid surgery in seven Portuguese hospitals between January 2018 and December 2020 (n=945). The data collected included the following parameters: age and gender of the patients, anticoagulation or anti-aggregating therapy, histological diagnoses, type of surgery, the presence or absence of postoperative drains, thyroid weight, length of hospital stay, postoperative complications, and reinterventions. In this study, surgical complications evaluated were limited to the presence of hematoma or seroma. A total of 945 patients who underwent thyroid surgery were included in the study. Twenty-seven patients (2.9%, n=27) experienced complications classified as hematomas or seromas. In the series, significant differences were observed between the two groups according to hypocoagulation or anti-aggregation status (OR=3.62; 95% CI 1.14-11.4) (p=0.001) and the nature of histological diagnosis (toxic vs. non-toxic benign disease) (OR=6.59; 95% CI 1.83-23.7). Hypocoagulation or anti-aggregation status were independently associated with a higher risk of complications. The presence of drains was associated with longer hospitalization periods (p<0.001) and not a decreased need for reintervention. Conclusion: Cervical hematoma or seroma are rare complications associated with both hypocoagulation and anti-aggregation therapy and with the presence of benign toxic pathology. The use of drains does not decrease the need for reintervention and is even associated with a longer length of hospital stay; therefore, their routine use should not be advised.

Abstract	According to the guidelines of the Intergovernmental Panel on Climate Change, carbon emissions are attributed to the producers of goods and services. This approach has been challenged by recent literature, advocating an attribution criterion based on consumers, i.e. accounting for the carbon embedded into the goods imported by each country. Quantifying the effectiveness of such a consumption-based accounting requires understanding the complex structure of the graph induced by the flows of emissions between world countries. To this aim, we have considered a balanced panel of a hundred of countries and constructed the corresponding Carbon Trade Network for each of the past twenty years. Our analysis highlights the tendency of each country to behave either as a 'net producer'-or 'net exporter'-of emissions or as a 'net consumer'-or 'net importer'-of emissions; besides, it reveals the presence of an unexpected, positive feedback: despite individual exchanges having become less carbon-intensive, the increasing trade activity has ultimately risen the amount of emissions directed from 'net exporters' towards 'net importers'. Adopting a consumption-aware accounting would re-distribute responsibility between these two groups, possibly reducing disparities.

Abstract	INTRODUCCIÓN: La infección del tracto urinario (ITU) se define como la invasión, colonización y proliferación bacteriana del tracto urinario. Se sabe que puede ser producida por diferentes microorganismos patógenos, pero actualmente existen pocos datos en relación a la etiología y resistencia a antimicrobianos en esta infección. Se sabe que esta patología es la segunda causa más frecuente de infecciones bacterianas en niños, y que es la responsable de gran número de consultas e internaciones a diario en el servicio de Pediatría. OBJETIVO: Describir el agente causal más prevalente de infecciones del tracto urinario en pacientes pediátricos y el perfil de sensibilidad antibiótica durante el periodo de enero 2015 hasta diciembre 2017 en Clínica Universitaria Reina Fabiola. MATERIALES Y METODOS: Estudio observacional, retrospectivo, descriptivo. Se realizó una recolección de datos, desde el sistema de microbiología, de pacientes con diagnóstico de ITU (basándonos en resultado positivo de urocultivo) que consultaron en el Servicio de Pediatría de la Reina Fabiola en el periodo de enero 2015 a diciembre 2017. Se evaluaron las siguientes variables: sexo, edad, resultado microbiológico de urocultivo y de antibiograma. Las variables se describieron con N (%) en caso de variables categóricas y medidas de posición y dispersión en caso de variables continuas. RESULTADOS: Se procesaron 3618 urocultivos resultando positivos 867 (24%), de los cuales 539 se incluyeron en el presente estudio por contar con datos completos. Se demostró una predominancia en el sexo femenino (83,8%) y el grupo etario donde predominaron las ITU fue entre el año y los 5 años N: 259 (48%). El microorganismo más frecuente fue la Escherichia coli, 441/539 81%), seguida por Proteus mirabillis (49/539 9%) y Klebsiella pneumoniae (12/539 2%). La Escherichia coli fue sensible a nitrofurantoina, cefazolina, ciprofloxacina, ampicilina sulbactam (83,2%) y en menor porcentaje a trimetropina sulfametoxazol, siendo resistente a ampicilina. El Proteus mirabillis y ...

Abstract	The geodynamic framework of Mount Etna volcano (Italy) is characterised by two superimposed tectonic domains: a compressional one, oriented N-S, and an extensional one, oriented approximately WNW-ESE. The combination of these two domains and the volcano activity, has generated a complex system of faults prevalently on the eastern flank of the volcano. The monitoring and analysis of the acceleration occurring on the eastern flank of Mount Etna is the keystone to understand the volcano-tectonic dynamics that involves the instability of this flank in a densely inhabited area.On the south-eastern flank the deformation is accommodated by several faults which have different kinematics and behaviours. The Fiandaca fault generated the 26 December 2018 earthquake, two days after the eruption of 24 December, which induced a clear post seismic deformation, detected by GNSS and InSAR data. In particular, we analyse the velocity field obtained by GNSS data of the permanent stations and discrete points. We discriminate the deformation occurred along the San Gregorio-Acitrezza fault, which is accommodated by the Nizzeti fault, and we analyse the post seismic deformation along the Linera fault. We analyse the Slow Slip Events (SSE) that are observed in the GNSS and InSAR time series in the vicinity of the Acitrezza fault and we quantify and discuss the tectonic origin of the Belpasso-Ognina lineament that we interpreted as a tear fault. Finally, we propose volcano-tectonic model of the south-eastern flank of Mount Etna which shows the anatomy of deformation occurred from 2016 to 2019.

Abstract	Obesity is a chronic multifactorial pathology determined by many factors, including incorrect eating habits and a low level of physical activity. There is an urgent need to promote a persistent change in lifestyle in obese subjects, but very few individuals maintain long-term results achieved after diet therapies. Therapeutic Education (TE) has taken over an important role as a multidisciplinary intervention aimed at improving lifestyle and at acquiring new skills for the management of the disease. However, only a small portion of patients can maintain participation in such programs and fully benefit from them. Assistive technologies, and in particular assistive social robots, are powerful tools to boost independence and improve participation in educational activities. The aim of the research work described in this article is to evaluate the effect of employing a social robot as a therapeutic educational robot helping the expert therapist in the education activity. This article describes the implementation, deployment, and evaluation of a social educational robot used as a TE assistant. Although we cannot provide statistically significant results due to the limited number of people involved in the experimental protocol, all experimental results show a positive trend, indicating that the robot can enhance the social interactions between the patients and the therapist and among the patients, thus bringing to better overall results of the TE sessions, measured with standard tests for obesity management.

Abstract	Jejunal gastrointestinal stromal tumors (GIST) are rare mesenchymal tumors of the gastrointestinal (GI) tract and a rare cause of massive GI bleeding. Due to this rarity and non-specific presentation, diagnosis and treatment may be difficult and often delayed. Urgent surgical intervention is crucial for controlling the source of bleeding and total tumor excision. Herein, we present the case of a 40-year-old male who presented to the emergency room (ER) with features of upper GI bleeding. He referred astheny and black stools, and was pale, sweaty, and tachycardic despite normal blood pressure. Rectal examination revealed melena, and laboratory findings revealed decreased hemoglobin (Hb) and elevated blood urea. Upper endoscopy was normal, and the Hb level dropped again to 6.9 g/dL; therefore, blood transfusion was required during ER observation. For further investigation, the patient underwent an angio-computed tomography scan, which revealed a lesion located in a jejunal loop as the probable bleeding source. Emergency exploratory laparotomy revealed a jejunal loop tumor. Segmental enterectomy containing the tumor was performed and the post-operative period was uneventful. The anatomopathological examination was compatible with low-risk GIST, and the multidisciplinary board agreed that surveillance was the best ongoing treatment. Due to the rarity of jejunal GIST as the cause of massive GI bleeding, diagnosis may be challenging, delaying prompt treatment with bleeding source control. In such cases, surgery may be both lifesaving and curative. Therefore, these tumors should not be forgotten when managing patients with occult GI bleeding with an atypical presentation to prevent delays in treatment and severe outcomes.

Abstract	Coordination protocols help programmers of distributed systems reason about the effects of transactions on the state of the system, but they're not cheap. Coordination protocols may involve multiple rounds of communication, which can hurt system responsiveness. There exist many efforts in distributed computing for managing the coordination-performance trade-off. More recent is a line of work that characterizes the class of workloads for which coordination is not necessary for consistency: namely, logically monotonic programs. In this paper, we present a case study of logical monotonicity in workloads typical to computational biology. We leverage the Bloom language to write efficient distributed programs, and compare their performance to equivalent programs written in UPC++, a popular language for writing distributed programs. Additionally, we leverage Bloom's analysis tools to identify points-of-coordination, and use our own experience using Bloom to recommend some higher-level abstractions for users without strong distributed computing backgrounds.

Abstract	The eastern slope of Mt. Etna is characterised by shallow seismicity originating from normal-oblique faulting, Timpe Fault System, related to WNW-ESE regional extension.Recent research has demonstrated that in the fault population of Mt. Etna's eastern flank the minimum earthquake magnitude that will have a ground rupture effect is ca. 2.5. This system is characterised by high frequency seismic activity, due to thinned seismogenic crustal layer. This characteristic, together with the high density of the fault segments, does not always for identification of the segments responsible for the earthquake. The earthquakes, affecting the medium-lower eastern flank, have been historically reconstructed by macroseismic analysis and reported in a macroseismic database, and in recent decades by instrumental seismic registration, which provide the seismological parameters capable of evaluating focal mechanism, hypocentre and relative algorithms related to geometric parameters which control the growth of fault segments.In this paper, we present a methodology to evaluate the age of the rapid exhumation of the free-face fault plane of the NNW-SSE oriented normal fault segment named S. Tecla (Timpe Fault System). It consists of the measurement of the thalli species (Lichenometry method) in order to evaluate the parameters which characterise their growth. The seismic history of the S. Tecla Fault indicates eight certain events from 1865 to 2005 with 3.4 ÷ 4.7 Magnitude (De Guidi et al., 2012 and reference therein). We found evidence of two different recent rapid vertical deformation events at the base of the S. Tecla fault escarpment, the oldest 20 m long and 0.25 m in height, and the youngest with a 0.02 m high nude surface exposed. We have observed that there are thalli of Xanthoparmelia conspersa (Ehrh. Ex Ach.) Hale, colonizing part of the nude surface on the escarpment. The results highlight that the oldest thalli was dated at 43.7 years old, showing that rapid vertical deformation generated the surface where the thalli, after 4 years, took root. The displacement of this surface could be related to the seismic events occurring on 3rd August 1973 (3.8 M) in S. M. Ammalati area probably accompanied by intense post seismic deformation. The second and last event could be attributable to a 3.1 M seismic event occurring on 25th September 2014 (ISIDe, 2016).

Abstract	Based on the use of automatic photogrammetry, different researchers made evident that the level of overlap between adjacent photographs directly affects the uncertainty of the 3D dense cloud originated by the Structure from Motion/Image Matching (SfM/IM) process. The purpose of this study was to investigate if, in the case of a convergent shooting typical of close-range photogrammetry, an optimal lateral displacement of the camera for minimizing the 3D data uncertainty could be identified. We examined five different test objects made of rock, differing in terms of stone type and visual appearance. First, an accurate reference data set was generated by acquiring each object with an active range device, based on pattern projection (
