Behavioral and personality features in patients with lateralized Parkinson's disease

Background: Dopamine neurotransmission plays a key role in several brain activities, including motor, cognitive, and behavioral functions. Parkinson's disease (PD) typically begins with asymmetrical motor features related to asymmetrical dopamine denervation. This study was designed to examine whether distinct cognitive, behavioral, and personality features are related to this asymmetry. Methods: Fifty-six patients with mild PD and lateralized motor features were grouped according to dominant side of motor features and evaluated using a neuropsychological assessment focused on attention and executive functions, impulse control disorders, and personality inventory. Results: There were no differences in neuropsychological functions between patients with right and left lateralized PD, but differences occurred in personality features. Patients with motor impairment predominant on the left-hand side had prevalence of hypomania and conversion profile. Conclusions: This study suggests that side dominance of dopaminergic denervation may be related to personality features in patients with PD that could influence behavioral aspects

Design of the PERSEO Registry on the management of patients treated with oral anticoagulants and coronary stent

Aim Percutaneous coronary intervention with stent implantation (PCI-S) in patients requiring chronic oral anticoagulant therapy (OAC) is associated with an increased risk of bleeding and ischemic complications. Different randomized studies showed a significant advantage of a double antithrombotic therapy and superiority of direct oral anticoagulant (DOAC) compared with warfarin, but real-world data are limited. Aim is to evaluate the antithrombotic management and clinical outcome of patients with an indication for OAC who undergo PCI-S in a 'real-world' setting. Methods The multicentre prospective observational PERSEO (PERcutaneouS coronary intErventions in patients treated with Oral anticoagulant therapy) Registry (ClinicalTrials.gov Identifier: NCT03392948) has been designed to enrol patients requiring OAC treated by PCI-S in 25 Italian centres. A target of at least 1080 patients will be followed for 1 year and data on thromboembolic and bleeding events and changes in antithrombotic therapy will be registered. The primary end point is a combined measure of efficacy and safety outcome (NACE), including major bleeding events and major adverse cardiac and cerebral events at 1-year follow-up in patients treated with DOAC (and dual or triple antiplatelet therapy) compared with the corresponding strategies with vitamin K antagonists. A secondary prespecified analysis has been defined to evaluate NACE in dual versus triple antithrombotic therapy after hospital discharge at 1-year follow-up. Conclusion The PERSEO Registry will investigate in a 'real world' setting the safety and efficacy of DOAC versus warfarin and dual versus triple antithrombotic therapy in patients with indication for oral anticoagulant therapy who undergo PCI-S

Reclamo al CICR- commento all'art.9 TUB

Il reclamo al CICR resta apparentemente immutato come reclamo nazionale avverso i provvedimenti di vigilanza, mentre gli assetti dei poteri di vigilanza bancaria sono da tempo profondamente riconfigurati e incentrati sulla BCE. Nel nuovo sistema di vigilanza è previsto un diverso procediento di reclamo. Si affronta, quindi, principalmente il problema della convivenza dei due rimedi

Experimental neutron capture data of 58Ni from the CERN n_TOF facility

The neutron capture cross section of 58Ni was measured at the neutron time of flight facility n_TOF at CERN, from 27 meV to 400 keV neutron energy. Special care has been taken to identify all the possible sources of background, with the so-called neutron background obtained for the first time using high-precision GEANT4 simulations. The energy range up to 122 keV was treated as the resolved resonance region, where 51 resonances were identified and analyzed by a multilevel R-matrix code SAMMY. Above 122 keV the code SESH was used in analyzing the unresolved resonance region of the capture yield. Maxwellian averaged cross sections were calculated in the temperature range of kT = 5 – 100 keV, and their astrophysical implications were investigated

GEANT4 simulation of the neutron background of the C6D6 set-up for capture studies at n_TOF

The neutron sensitivity of the C6D6 detector setup used at n_TOF facility for capture measurements has been studied by means of detailed GEANT4 simulations. A realistic software replica of the entire n_TOF experimental hall, including the neutron beam line, sample, detector supports and the walls of the experimental area has been implemented in the simulations. The simulations have been analyzed in the same manner as experimental data, in particular by applying the Pulse Height Weighting Technique. The simulations have been validated against a measurement of the neutron background performed with a natC sample, showing an excellent agreement above 1 keV. At lower energies, an additional component in the measured natC yield has been discovered, which prevents the use of natC data for neutron background estimates at neutron energies below a few hundred eV. The origin and time structure of the neutron background have been derived from the simulations. Examples of the neutron background for two different samples are demonstrating the important role of accurate simulations of the neutron background in capture cross-section measurements

Fission fragment angular distribution measurements of 235U and 238U at CERN n_TOF facility

Neutron-induced fission cross sections of 238U and 235U are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross sections. Therefore, the detection effciency should be corrected by using the angular distribution of the fission fragments (FFAD), which are barely known above 20 MeV. In addition, the angular distribution of the fragments produced in the fission of highly excited and deformed nuclei is an important observable to investigate the nuclear fission process. In order to measure the FFAD of neutron-induced reactions, a fission detection setup based on parallel-plate avalanche counters (PPACs) has been developed and successfully used at the CERN-n_TOF facility. In this work, we present the preliminary results on the analysis of new 235U(n,f) and 238U(n,f) data in the extended energy range up to 200 MeV compared to the existing experimental data
