Background: Since the first case of Coronavirus Disease 2019 (COVID-19) in Italy, all the hospital facilities had to reform their daily activities. Amidst them, the Interventional Radiology Department in the “Azienda Ospedaliera Universitaria” of Novara (Italy) had to create a dedicated protocol for the patent’s management during the pandemic.Design and Methods: The time interval between February 2020 and March 2021 was divided into three different periods and we reported the evolution of our safety protocol, the changes in our daily activities and the rates of Sars-CoV-2 infection among the healthcare workers (HCW) of the Angiographic Suite. Personnel who had positive partners/family members or who had established close contacts of another nature outside the workplace were excluded from the study, in order to reduce any bias.Results: A total of 35 HCWs served in 355 patient procedures on Sars-CoV-2 positive patients from February 2020 to March 2021. During the year there was a reduction in the morbidity rate first from 7.9% to 1.4% and then currently reaching 0%.Conclusions: Dedicated routes, elevators, establishing Filter Areas and a clear demarcation between clean and contaminated areas, Dressing and undressing procedures, Cleaning procedures and the obligation to always wear a surgical mask during the working shift are essential to prevent in-hospital infection. The vaccines’ arrival seems to further reduce the risk for healthcare workers, but it is still necessary to take docile precautions in view of the new mutations of the virus.

Abstract. The STAFF-DWP wave instrument on board the equatorial spacecraft (TC1) of the Double Star Project consists of a combination of 2 instruments which are a heritage of the Cluster mission: the Spatio-Temporal Analysis of Field Fluctuations (STAFF) experiment and the Digital Wave-Processing experiment (DWP). On DSP-TC1 STAFF consists of a three-axis search coil magnetometer, used to measure magnetic fluctuations at frequencies up to 4 kHz and a waveform unit, up to 10 Hz, plus snapshots up to 180 Hz. DWP provides several onboard analysis tools: a complex FFT to fully characterise electromagnetic waves in the frequency range 10 Hz-4 kHz, a particle correlator linked to the PEACE electron experiment, and compression of the STAFF waveform data. The complementary Cluster and TC1 orbits, together with the similarity of the instruments, permits new multi-point studies. The first results show the capabilities of the experiment, with examples in the different regions of the magnetosphere-solar wind system that have been encountered by DSP-TC1 at the beginning of its operational phase. An overview of the different kinds of electromagnetic waves observed on the dayside from perigee to apogee is given, including the different whistler mode waves (hiss, chorus, lion roars) and broad-band ULF emissions. The polarisation and propagation characteristics of intense waves in the vicinity of a bow shock crossing are analysed using the dedicated PRASSADCO tool, giving results compatible with previous studies: the broad-band ULF waves consist of a superimposition of different wave modes, whereas the magnetosheath lion roars are right-handed and propagate close to the magnetic field. An example of a combined Cluster DSP-TC1 magnetopause crossing is given. This first case study shows that the ULF wave power intensity is higher at low latitude (DSP) than at high latitude (Cluster). On the nightside in the tail, a first wave event comparison - in a rather quiet time interval - is shown. It opens the doors to future studies, such as event timing during substorms, to possibly determine their onset location.

Background: Secretory and medullary carcinomas of the breast are rare subtypes of infiltrating ductal carcinoma. The different histological behavior of medullary and secretory carcinomas is correlated with different imaging features on mammography, ultrasound, and magnetic resonance imaging. Case Report: We report the case of a Caucasian woman in which both subtypes of tumors were diagnosed in an 8-year time interval and evaluate, in antithesis, histopathological and imaging aspects of medullary and secretory carcinoma. Conclusion: To our knowledge, this is the first case reported in literature of secretory carcinoma with a complete imaging tumor evaluation in a patient with a previous contralateral medullary cancer.

A well-known prediction is that the growing elderly population will place a strain on our healthcare systems. At the same time, healthcare is becoming increasingly patient-centered and individualized, with the patient becoming an active participant rather than a mere object of healthcare. The need for change may be met by using a reablement service, utilizing the rehabilitation mindset through home-based services. Rehabilitation and reablement aim to provide opportunities for individuals to participate to a maximum of their potential. This study is part of a larger research project exploring different aspects of reablement in municipalities. It aims to describe how older adults engage in daily activities within the context of reablement and to explore participation in daily activities. A qualitative design was chosen, and the study is explorative in nature due to limited research on participants’ experience with reablement. Ten older adults age 70 to 94 years old were recruited and interviewed. The interviews were transcribed verbatim and analyzed using systematic text condensation (STC) strategies. This study provides insights on how older adults experience participation in daily activities and important aspects for performing these activities and living independently as long as possible. Based on the older adults’ experiences, three main themes were identified when receiving reablement. First, what to achieve with reablement and feeling a sense of security to participate in daily activities. Second, how to carry out wanted activities using different skills and last, how the social network is important for enabling active living. This calls for healthcare workers to address and facilitate these in reablement. Our findings show the importance of collaborating with the social network and strengthening participation in daily activities to establish and develop existing reablement services.

A colony of albino rats was developed from three breeders (not germ-free) originally delivered by Cesarian section and artificially reared in the laboratories of Professor James A Reyniers. The colony has been maintained under quarantine since June, 1948, in the absence of any demonstrable involvement of the respiratory tract or of the middle ears. At autopsy pleuropneumonia-like organisms, Streptobacillus moniliformis, and the virus-like agent associated with endemic pneumonia were not recoverable from the lungs or the nasal passages of 81 young and adult rats. During the same time interval the morbidity rate of pneumonia in another rat colony known to be free from infectious catarrh was 51 per cent while the incidence of infection with the virus-like agent approached 100 per cent.

Background Portomesenteric vein thrombosis may be life-threatening due to bowel ischemia caused by venous stasis, or variceal bleeding caused by portal hypertension. Purpose To evaluate the effectiveness and safety of recanalization combined with transjugular intrahepatic portosystemic shunt in acute and chronic portomesenteric vein thrombosis in patients with and without liver cirrhosis. Material and Methods 21 consecutive patients (5 women, 16 men; mean 48 years) with portomesenteric vein thrombosis (8 acute, 13 chronic) treated at the Interventional Radiology department between March 2014 and September 2018 were retrospectively reviewed. The main portal vein was completely obliterated and the portomesenteric vein thrombosis extended into the superior mesenteric vein in all patients. The portomesenteric vein thromboses were recanalized transhepatically, a transjugular intrahepatic portosystemic shunt was inserted, thrombectomy was performed in acute portomesenteric vein thrombosis, and angioplasty with or without additional stenting was performed in chronic portomesenteric vein thrombosis. Results Recanalization was successful in 8/8 patients (100%) with acute portomesenteric vein thrombosis, and in 11/13 patients (85%) with chronic portomesenteric vein thrombosis. In 12 patients, blood flow was restored in one session. Several sessions were more frequently needed in patients with acute portomesenteric vein thrombosis compared to those with chronic portomesenteric vein thrombosis ( p = 0.003). Re-occlusion occurred and was recanalized in 10/19 patients and was more frequent in patients with chronic ( n = 8/11) than on those with acute ( n = 2/8) portomesenteric vein thrombosis ( p = 0.04). Adverse events occurred in five patients. There was no 30-day mortality. Conclusion Recanalization and insertion of a transjugular intrahepatic portosystemic shunt is safe and effective in patients with acute and chronic portomesenteric vein thrombosis with or without cirrhosis. Recanalization was more likely to stay patent in acute compared with chronic portomesenteric vein thrombosis.

Abstract Objective: To describe the technique of injecting hemostatic matrix, as well as the experience of our interventional radiology department in its application. Materials and Methods: We conducted a single-center study with retrospective analysis of the experience of our group in the use of hemostatic gelatin matrix in percutaneous biopsies. Results: In a total of 73 biopsies in different organs, such as the liver, kidney, and spleen, hemostatic gelatin matrix was introduced into the coaxial needle. The only complication observed was migration of the hemostatic matrix to the left kidney collecting system, and that was resolved with clinical treatment. There were no cases of bleeding after the injection of hemostatic matrix. Conclusion: The use of hemostatic matrices in the path of percutaneous biopsies is another tool available for consideration in minimally invasive procedures.

The Magnetic Field

When the magnetic field of a planet is due to self-exciting hydromagnetic dynamo action in an electrically conducting fluid core surrounded by a poorly-conducting ‘mantle', a recently proposed method (Hide 1978,1979) can in principle be used to find the radius r c of the core from determinations of secular changes in the magnetic field B in the accessible region above the surface of the planet, mean radius r s , with a fractional error in r c of the order of, but somewhat larger than, the reciprocal of the magnetic Reynolds number of the core. It will be possible in due course to apply the method to Jupiter and other planets if and when magnetic measurements of sufficient accuracy and detail become available, and a preliminary analysis of Jovian data (Hide & Malin 1979) has already given encouraging results. The ‘magnetic radius’ ̄r̄ c of the Earth’s molten iron core has been calculated by using one of the best secular variation models available (which is based on magnetic data for the period 1955-75), and compared with the ‘seismological’ value of the mean core radius, r c = 3486 ± 5 km. Physically plausible values of r̄ c are obtained when terms beyond the centred dipole ( n = 1) and quadrupole ( n = 2) in the series expansion in spherical harmonics of degree n = 1,..., ^ n ,..., n * are included in the analysis (where 2 ≼ ^ n ≼ n *≼ ∞). Typical values of the fractional error ( r̄ c - r c ) / r c amount to between 0.10 and 0.15. Somewhat surprisingly, this error apparently depends significantly on the value of the small time interval considered; the error of 2% found in the first case considered, for which ^ n — n * = 8 and for the time interval 1965-75, is untypically low. These results provide observational support for theoretical models of the geomagnetic secular variation that treat the core as an almost perfect conductor to a first approximation except within a boundary layer of typical thickness much less than 1 km at the core-mantle interface.

Exact Definition

A noção de velocidade é frequentemente utilizada por pessoas em suas atividades diárias, sendo um dos objetos formais de estudos da Física. A preocupação em encontrar uma definição exata para este conceito levou vários pesquisadores a formularem diversas teorias. A mecânica newtoniana propõe a velocidade como uma função da distância percorrida em um dado intervalo de tempo (Velocidade = Distância/Tempo), já a teoria da Relatividade, proposta por Einstein, sugere que a velocidade seja definida em função do tempo. No entanto, pode-se indagar sobre como este conceito se constrói nas estruturas cognitivas do sujeito, isto é, a noção de velocidade se estrutura individualmente, ou depende do tempo? Existem outros fatores que influenciam na construção desta noção? Desta forma, este trabalho tem como objetivo investigar como se desenvolve a noção de velocidade em crianças de sete a onze anos de idade, segundo a Epistemologia Genética de Piaget, utilizando como metodologia para coleta de dados, o Método Clínico Crítico. Entende-se que, com os resultados deste trabalho, é possível compreender que a noção de velocidade apresenta um caráter construtivo na estrutura cognitiva das crianças, assim como o conhecimento em geral, e que só ao final do estágio operatório-concreto o sujeito é capaz de argumentar com segurança sobre o referido conceito. Palavras-chave: Construção do Conhecimento. Método Clínico Crítico. Operatório-Concreto. AbstractThe notion of speed is often used by people in their daily activities, one of the formal objects of physics’ study. The concern to find an exact definition for this concept has led many researchers to formulate several theories. Newtonian mechanics proposes the speed as a function of distance traveled in a given time interval (speed = distance / time); since the theory of relativity proposed by Einstein suggests that the speed is defined as a function of time. However, we may ask how this concept is built on the cognitive structures of the subject, that is, the notion of speed is structured individually, or does it depend on time? Are thereother factors that influence the construction of this notion? Thus, this study aims to investigate how to develop the notion of speed in children from seven to eleven years of age, according to Piaget’s Genetic Epistemology, using as a methodology for data collection, his Clinical Method Critical. We believe that with the results of this work, we can understand that the notion of speed has a constructive character in the Children’s cognitive structure, as well as knowledge in general, and only at the end of operative concrete stage the subject is able to argue with safety that concept. Keywords: Knowledge Construction. Clinical Critical Method. Operative-Concrete.
