Clinical and radiological outcomes following insertion of a novel removable percutaneous interspinous process spacer: an initial experience.

Purpose: To evaluate clinical and radiological outcomes of a series of patients treated with a removable percutaneous interspinous process spacer (IPS) (LobsterProject® Techlamed®) for symptomatic degenerative lumbar spinal stenosis (DLSS).

Methods: All patients treated in two centres with this IPS during 2019 were retrospectively reviewed. Procedures were performed under deep sedation or general anaesthesia by two interventional radiologists.

Psychological Impact of the Very Early Beginning of the COVID-19 Outbreak in Healthcare Workers: A Bayesian Study on the Italian and Swiss Perspectives.

Background: We investigated the COVID19-related psychological impact on healthcare workers in Italy and in Italian-speaking regions of Switzerland, three weeks after its outbreak. All professional groups of public hospitals in Italy and Switzerland were asked to complete a 38 questions online survey investigating demographic, marital and working status, presence of stress symptoms and need for psychological support.

Results: Within 38 h a total of 3,038 responses were collected.

CT-Guided Percutaneous Vertebroplasty for Vertebral Non-union Following Posterior Fixation: A Preliminary Retrospective Study.

Purpose: Traumatic thoracolumbar vertebral fractures are frequently treated with posterior fixation (PF) and vertebral augmentation. Sometimes, it is deemed too risky to offer vertebral augmentation under fluoroscopic guidance alone. Adjuvant CT/fluoroscopy-guided percutaneous vertebroplasty (PVP) could be offered in certain scenarios.

Lung Function and Symptoms in Post-COVID-19 Patients: A Single-Center Experience.

Objective: To address the lack of information about clinical sequelae of coronavirus disease 2019 (COVID-19).

Patients And Methods: Previously hospitalized COVID-19 patients who were attending the outpatient clinic for post-COVID-19 patients (ASST Ovest Milanese, Magenta, Italy) were included in this retrospective study. They underwent blood draw for complete blood count, C-reactive protein, ferritin, D-dimer, and arterial blood gas analysis and chest high-resolution computed tomography (HRCT) scan.

Intraoperative breast specimen assessment in breast conserving surgery: comparison between standard mammography imaging and a remote radiological system.

Objective: To compare standard specimen mammography (SSM) with remote intraoperative specimen mammography (ISM) assessment in breast conserving-surgery (BCS) based on operative times, intraoperative additional excision (IAE) and re-intervention rates.

Methods And Materials: We retrospectively compared 129 consecutive patients (136 lesions) who had BCS with SSM at our centre between 11/2011 and 02/2013 with 138 consecutive patients (144 lesions) who underwent BCS with ISM between 08/2014 and 02/2015.SSM or ISM were performed to confirm the target lesions within the excised specimen and margin adequacy.

Structural stability and uniformity of magnetic Pt nanoparticles in NaY zeolite.

Based on first-principles calculations, the structural stability and magnetic variety of Pt nanoparticles encapsulated in a NaY zeolite are investigated. Among 50 stable isomers in the gas phase, due to geometrical constraints, only about 1/3 of those clusters can be inserted in the zeolite pores. Severe structural rearrangements occur depending on whether the solid angle at the Pt vertex bound to the super-cage is larger than 2 sr (i.

Multiscale approach for studying melting transitions in CuPt nanoparticles.

A multiscale approach, based on the combination of CALPHAD and molecular dynamics (MD) simulation, is applied in order to understand the melting transition taking place in CuPt nanoalloys. We found that in systems containing up to 1000 atoms, the morphology adopted by the nanoparticles causes the icosahedral CuPt to melt at temperatures 100 K below that of the other morphologies, if the chemical composition contains less than 30% of Pt. We show that the solid-to-liquid transition in CuPt nanoparticles of a radius equal to or greater than 3 nm could be studied using classical tools.

Multiparametric Gd-EOB-DTPA magnetic resonance in diagnosis of HCC: dynamic study, hepatobiliary phase, and diffusion-weighted imaging compared to histology after orthotopic liver transplantation.

Purpose: To evaluate Gd-EOB-DTPA-enhanced magnetic resonance (MR) performance during dynamic (DYN) phases, hepatobiliary (HB) phase and diffusion-weighted imaging (DWI) compared with pathological findings in patients undergoing orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) associated with different conditions, such as stage of chronic liver disease, histological grading, nodule size, and occurrence of previous treatments.

Methods: Retrospective analysis of 64 nodules reported as HCC at pathological analysis on 28 explanted livers, examined about 3 months before OLT using a 1.5 T device and 16 channels array after intravenous GD-EOB-DTPA injection.
