TECHNOLOGICAL PERSPECTIVES REGARDING THE APPLICATION OF THE CONTACT BREAKING ELECTRICAL DISCHARGE MACHINING PROCESS USING AS ELECTRODE-TOOL - METAL B…
2020
The scientific paper presents the most important aspects of theoretical and practical nature regarding the possibilities of processing metallic materials using the contact breaking electrical discharge machining with transfer object-metal band. The exposed research is based on the experience gained over the years by a team of Romanian researchers and university professors who managed to patent a metal material cutting plant using the process of contact breaking electrical discharge machining with transfer object-metal band. The scientific paper presents a radiography of some studies and research carried out over the years in the previous field presented.
Pełna trójnaczyniowa rewaskularyzacja wieńcowa z użyciem ultra niskich dawek kontrastu jako strategia zachowania rezydualnej funkcji nerek u chorego …
2018
Nefropatia indukowana kontrastem jest poważnym powikłaniem koronarografii i przezskórnych interwencji wieńcowych (PCI) u chorych z przewlekłymi schorzeniami nerek. Jedyną realną strategią zapobiegawczą przed jej rozwojem jest adekwatne nawodnienie wraz z ograniczeniem objętości stosowanego kontrastu. Ostatnio zaproponowano nowe techniki diagnostyczne i terapeutyczne polegające na stosowaniu ultra niskich dawek kontrastu, co więcej opisano zabiegi PCI bez użycia kontrastu. W niniejszym artykule prezentujemy przypadek dializowanego chorego z ostrym zespołem wieńcowym i ciężką niewydolnością jedynej nerki, ale z zachowaną rezydualną jej funkcją, u którego przeprowadzono diagnostykę i pełną tró…

Retrograde Chronic Total Occlusion Percutaneous Coronary Interventions: Predictors of Procedural Success From the ERCTO Registry
2022
Objectives: The aim of this study was to identify independent predictors of procedural success after retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Background: Retrograde CTO PCI is an established technique, but predictors of success remain poorly understood. Methods: A multivariable logistic regression model was used to analyze potentially important demographic, clinical, anatomical, and technical aspects of retrograde CTO PCI cases uploaded to the multicenter European CTO (ERCTO) Club Registry. Results: In calendar years 2018 and 2019, 2,364 retrograde CTO PCI cases constituted the primary analysis cohort. A primary retrograde strategy was used in 1,953…
Reproducibility of Rolandic beta rhythm modulation in MEG and EEG
2022
The Rolandic beta rhythm, at ∼20 Hz, is generated in the somatosensory and motor cortices and is modulated by motor activity and sensory stimuli, causing a short lasting suppression that is followed by a rebound of the beta rhythm. The rebound reflects inhibitory changes in the primary sensorimotor (SMI) cortex, and thus it has been used as a biomarker to follow the recovery of patients with acute stroke. The longitudinal stability of beta rhythm modulation is a prerequisite for its use in long-term follow-ups. We quantified the reproducibility of beta rhythm modulation in healthy subjects in a 1-year-longitudinal study both for MEG and EEG at T0, 1 month (T1-month, n = 8) and 1 year (T1-ye…
Retallades en l'estat del benestar i burnout
2013
The current recession and economic crisis of capital that is taking place throughout Europe, as well as the antisocial measures that accompany it, are causing the extinction in the short and medium term of the so-called Welfare State, at a different speed in every EU Member State. We are professionals of the social sphere and we are used to work with usual and recent victims of such crisis. However, this time we are victims too as a consequence of the cutbacks, privatization processes and elimination of benefits and services that are being put into practice. As Social Workers we should consider to take action from the teaching, professional practice and scientific thought fronts in order to…
Management of Acute Kidney Injury and Extracorporeal Blood Purification Therapies During the COVID-19 Pandemic: The Italian SIN–SIAARTI Joint Survey …
2022
Background and AimThe novel coronavirus disease 2019 remains challenging. A large number of hospitalized patients are at a high risk of developing AKI. For this reason, we conducted a nationwide survey to assess the incidence and management of AKI in critically ill patients affected by the SARS-CoV-2 infection.MethodsThis is a multicenter, observational, nationwide online survey, involving the Italian Society of Nephrology and the critical care units in Italy, developed in partnership between the scientific societies such as SIN and SIAARTI. Invitations to participate were distributed through emails and social networks. Data were collected for a period of 1 week during the COVID-19 pandemic…
Use of Battery- vs. Petrol-Powered Chainsaws in Forestry: Comparing Performances on Cutting Time
2022
The use of battery tools is very common in many fields of work. In fact, the electric engine and batteries have several advantages over traditional endothermic engines, including low emissions, in terms of pollutants, vibration and noise. In this context, the chainsaw market started producing electric models powered by batteries. These machines can be useful in forestry, but information on their performance is scarce. The aim of this work was to compare the performance, in terms of cutting times, of three Stihl chainsaw models: the MS 220C-B (battery powered), and the MS 201 C-M and MS 261 C-M (both petrol powered). The study was carried out on five different wood species, also taking into …
Is it possible to make a diagnosis of raw, heated and baked egg allergy in children using cut-offs? A systematic review
2015
The diagnosis of IgE-mediated egg allergy lies both on a compatible clinical history and on the results of skin prick tests (SPTs) and IgEs levels. Both tests have good sensitivity but low specificity. For this reason, oral food challenge (OFC) is the ultimate gold standard for the diagnosis. The aim of this study was to systematically review the literature in order to identify, analyze, and synthesize the predictive value of SPT and specific IgEs both to egg white and to main egg allergens and to review the cutoffs suggested in the literature. A total of 37 articles were included in this systematic review. Studies were grouped according to the degree of cooking of the egg used for OFC, age…
Dermatoscopia del carcinoma basocelular: diagnóstico precoz, detección de recidiva e identificación de subtipos histológicos
2015
La dermatoscopia, o microscopía de epiluminiscencia, es una técnica diagnóstica in vivo no invasiva que permite visualizar estructuras morfológicas como el pigmento y los vasos no detectables a simple vista. Se convierte así en el puente entre el examen clínico macroscópico y el análisis anatomopatológico. Posiblemente la dermatoscopia podría ayudar a identificar lesiones tumorales muy incipientes o recidivas en estadio inicial, lo que permitiría un tratamiento precoz. También permitiría optimizar los procesos diagnósticos y terapéuticos según el subtipo histológico de carcinoma basocelular, todo lo cual conllevaría una reducción de la morbimortalidad para los pacientes y de los costes sani…
