Effects of More-Affected vs. Less-Affected Motor Cortex tDCS in Parkinson’s Disease
2017
Objective. To evaluate therapeutic potential of different montages of transcranial direct current stimulation (tDCS) in Parkinson’s Disease (PD) patients with asymmetric motor symptoms. Materials and Methods. Fourteen patients with asymmetric PD underwent, while on treatment, seven separate sessions including electrophysiological and clinical evaluation at baseline and after anodal, cathodal and sham tDCS of the primary motor cortex (M1) of the two hemispheres. Changes in motor cortical excitability were evaluated by transcranial magnetic stimulation. Effects on motor symptoms were assessed by testing finger tapping and upper limb bradykinesia, and by using the Italian validated Movement Di…
Steatosis affects the performance of liver stiffness measurement for fibrosis assessment in patients with genotype 1 chronic hepatitis C.
2014
Background & Aims: In Chronic Hepatitis C (CHC), the influence of steatosis on liver stiffness measurement (LSM) is still debated. We assessed the impact of steatosis and its ultrasonographical sign – bright liver echo pattern (BLEP) – on LSM values and on transient elastography (TE) accuracy for the diagnosis of liver fibrosis, in a cohort of consecutive patients with Genotype 1 (G1) CHC. Methods: Patients (n = 618) were assessed by clinical, ultrasonographic and histological (Scheuer score) features. TE was performed using the M probe. Results: Male gender (p = 0.04), steatosis as continuous variable (p <0.001), severity of necroinflammation (p = 0.02) and stage of fibrosis (p <0.001) wer…
Presence and distribution of the brown bear (Ursus arctos) in Friuli Venezia Giulia, from 2004 to 2011, through the non-invasive genetic monitoring a…
2012
After having disappeared at the beginning of 1900, the brown bear has started in a late 1960s a slow process of recolonization of the north-eastern Alps, through an expansion of Dinaric population. At the end of the 1990s the University of Udine began the occasional monitoring of the species and from 2004 non-invasive genetic monitoring became systematic. In the last 8 years 217 hair traps have been activated in the region to monitore: Natisone Valleys, the Julian and Carnic Alps and Prealps. Twenty-six hair traps were monitored in all years, whereas 40 were observed only in 2004, 2007 and 2011. The 26 hair traps constantly monitored from 2004 to 2011 showed 17% of average success of hair’s…
A questionnaire to collect unintended effects of transcranial magnetic stimulation: A consensus based approach
2022
Transcranial magnetic stimulation (TMS) has been widely used in both clinical and research practice. However, TMS might induce unintended sensations and undesired effects as well as serious adverse effects. To date, no shared forms are available to report such unintended effects. This study aimed at developing a questionnaire enabling reporting of TMS unintended effects. A Delphi procedure was applied which allowed consensus among TMS experts. A steering committee nominated a number of experts to be involved in the Delphi procedure. Three rounds were conducted before reaching a consen-sus. Afterwards, the questionnaire was publicized on the International Federation of Clinical Neurophysiolo…
La diagnostica chimico-fisica a supporto della conservazione e del restauro delle opere cartacee
2017
Questo contributo è stato prodotto a seguito dell’intervento del Prof. Caponetti e della sessione laboratoriale guidata dalla Dott.ssa Saladino in collaborazione con il Dott. Renda e la Dott.ssa Chirco in cui è stata realizzata una dimostrazione pratica di come si possano eseguire le indagini di materiale cartaceo con strumentazione portatile. Nel presente contributo sono presentate e illustrate alcune delle tecniche di indagine idonee per l’analisi di opere cartacee, ed in particolare alcune di quelle che possono essere applicate mediante strumentazione portatile. Queste tecniche forniscono informazioni complementari e consentono la conoscenza dell’opera stessa (tipologia di carta, tecnica…
Geophysical and geotechnical investigations to support the restoration project of the Roman ‘Villa del Casale’, Piazza Armerina, Sicily, Italy
2011
A multidisciplinary geophysical and geotechnical study, including some non-invasive geophysical applications, was carried out during the restoration of the ‘Villa del Casale’, a Roman villa discovered near Piazza Armerina (Sicily, Italy) in 1929, famous for its Roman floor mosaics. The project aims were to characterize the geology of the subsoil and provide information for solving the main building structural problems including the subsidence of some parts of the floor and the detachment of the tesserae (i.e., the tiles) of the mosaics. Another goal was the detailed study of the underground structures of the Corridor of the Great Hunt, a part of the villa strongly affected by subsidence and…
The Relevance of Noninvasive Tools To Assess Fibrosis in Non-Alcoholic Fatty Liver Disease.
2020
Non-alcoholic fatty liver disease (NAFLD) is a growing cause of chronic liver diseases worldwide, involving about 25% of people. NAFLD incorporates a large spectrum of pathological conditions, from simple steatosis to non-alcoholic steatohepatitis (NASH), cirrhosis and its complications include hepatic decompensation and hepatocellular carcinoma (HCC). This progression occurs, over many years, in an asymptomatic way, until advanced fibrosis appears. Thus, the differentiation of NASH from simple steatosis and identification of advanced hepatic fibrosis are key issues. To date, the histological assessment of fibrosis with liver biopsy is the gold standard, but obviously, invasiveness is the …
Predictors of non-invasive ventilation tolerance in amyotrophic lateral sclerosis
2011
Abstract Background The most frequent cause of death in patients with Amyotrophic Lateral Sclerosis (ALS) is respiratory failure. Recently, it has been shown that non-invasive ventilation improves survival and quality of life in ALS patients with respiratory failure, but little is known about predictors of non-invasive ventilation adaptation and tolerance. In this study we evaluated the effect of a comprehensive information about non-invasive ventilation use and a prolonged and intensive monitoring on tolerance to this palliative care. Methods We prospectively monitored all consecutive ALS patients with chronic respiratory failure and indication to non-invasive ventilation between January 2…
N-BiPAP vs n-CPAP in term neonate with respiratory distress syndrome
2020
Abstract Background Non-invasive respiratory ventilation has greatly improved the evolution of respiratory distress in neonates, especially for preterm infants, but few studies have investigated the use of non-invasive ventilation (NIV) in term infants. It is useful for neonatologists and nurses to identify the optimal ventilation strategy in terms of effectiveness for this group of newborns. The aim of our study was to investigate what type of respiratory support between nasal Continuous Positive Airway Pressure (nCPAP) or nasal Biphasic Positive Airway Pressure (nBiPAP) is more effective in term neonates with RDS. Methods Our study was a retrospective observational study of 78 full term n…
Cardiac kinematic parameters computed from video of in situ beating heart
2017
AbstractMechanical function of the heart during open-chest cardiac surgery is exclusively monitored by echocardiographic techniques. However, little is known about local kinematics, particularly for the reperfused regions after ischemic events. We report a novel imaging modality, which extracts local and global kinematic parameters from videos of in situ beating hearts, displaying live video cardiograms of the contraction events. A custom algorithm tracked the movement of a video marker positioned ad hoc onto a selected area and analyzed, during the entire recording, the contraction trajectory, displacement, velocity, acceleration, kinetic energy and force. Moreover, global epicardial veloc…
