Time-of-flight ERD with a 200mm2 Si3N4 window gas ionization chamber energy detector

2014

Abstract Low energy heavy ion elastic recoil detection work has been carried out in Jyvaskyla since 2009 using home made timing detectors, a silicon energy detector and a timestamping data acquisition setup forming a time-of-flight–energy telescope. In order to improve the mass resolution of the setup a new energy detector was designed to replace the silicon solid state detector, which suffered from radiation damage and had poor resolution for heavy recoils. In this paper the construction and operation of an isobutane filled gas ionization chamber with a 14 × 14 mm 2 100 nm thick silicon nitride window are described. In addition to greatly improved energy resolution for heavy ions, the dete…

Optical techniques: non-intrusive river monitoring approach

2022

<p>Technological advances over last decades gave an innovative impulse to development of new streamflow measurements techniques, making possible to implement remote flow monitoring methods that allow for non-intrusive measurements. Here, we focus on image-based techniques that involve the use of digital camera, either installed on a bridge or equipped by a drone (UAVs – Unmanned Aerial Vehicles). The most widely known and used optical techniques are the Large-Scale Particle Image Velocimetry and the Large-Scale Particle Tracking Velocimetry. Optical techniques are based on four main steps: (i) seeding and recording, (ii) images pre-processing, (iii) images proces…

Surface investigation of plasma HMDSO membranes post-treated by CF4/Ar plasma

2002

Fluorination treatment has been performed on polysiloxane membranes using a plasma glow discharge of a gases mixture CF4 and argon (plasma enhanced chemical vapor deposition). Atomic force microscopy, XPS analyses and contact angle measurements have been undertaken to explain the surface transformation and behavior, which strongly depend on the morphology, the composition and the hydrophilic/hydrophobic character of the plasma-polymerized initial membranes. Main result is that fluorination, which leads to hydrophobic membranes, has a more relevant effect on amorphous silica-like membranes than on polymer-like ones, according to their chemical composition whereas the plasma surface reaction …

Osteoporosis: Economic Burden of Disease in Italy.

2020

Background and Objective: Today, osteoporosis is the most common bone disease and an important public health problem in all developed countries. The objective of this study was to estimate the costs associated with the management and treatment of osteoporosis in order to assess the economic burden in Italy for 2017, in terms of direct medical costs and social security costs. Methods: A cost of illness model was developed to estimate the average cost per year sustained by the NHS (National Health Service) and Social Security System in Italy. A systematic literature review was performed to obtain epidemiological, direct and indirect costs parameters where available. Hospitalisation costs were…

The multifaceted spectrum of liver cirrhosis in older hospitalised patients: Analysis of the REPOSI registry

2021

Abstract Background Knowledge on the main clinical and prognostic characteristics of older multimorbid subjects with liver cirrhosis (LC) admitted to acute medical wards is scarce. Objectives To estimate the prevalence of LC among older patients admitted to acute medical wards and to assess the main clinical characteristics of LC along with its association with major clinical outcomes and to explore the possibility that well-distinguished phenotypic profiles of LC have classificatory and prognostic properties. Methods A cohort of 6,193 older subjects hospitalised between 2010 and 2018 and included in the REPOSI registry was analysed. Results LC was diagnosed in 315 patients (5%). LC was ass…

Risk assessment in ginecology and obstetrics in Sicily: an approach based on Wolff's Criteria

2013

Objectives To apply Wolff’s Criteria to hospital discharge records (HDR) in order to detect adverse events worthy of further study. Methods Gynecology and Obstetrics Units of three Sicilian hospitals were considered and HDR regarding ordinary and day hospital admissions in 2008 were collected. A matched case-control study was designed, by random selection of 10 controls at maximum for each case. Matching was performed on the variables age and speciality of admission (gynecology or obstetrics). Results Out of a total of 7011 HDR examined, 114 cases were identified with Wolff’s Criteria. Multivariate analysis confirmed a statistically significant association with the origin of admission, diag…

2019

We aimed to compare the clinical data at first presentation to inpatient treatment of children (<14 years) vs. adolescents (≥14 years) with anorexia nervosa (AN), focusing on duration of illness before hospital admission and body mass index (BMI) at admission and discharge, proven predictors of the outcomes of adolescent AN. Clinical data at first admission and at discharge in 289 inpatients with AN (children: n = 72; adolescents: n = 217) from a German multicenter, web-based registry for consecutively enrolled patients with childhood and adolescent AN were analyzed. Inclusion criteria were a maximum age of 18 years, first inpatient treatment due to AN, and a BMI <10th BMI percentile …

Inanspruchnahme von Selbsthilfegruppen und Psychotherapie im Anschluss an eine stationäre psychosomatisch-psychotherapeutische Behandlung

2007

Until now little is known about the role of participation in self-help groups alone or combined with psychotherapy in post-in-patient care. In the present study 2933 patients were questioned about their experience of self-help groups and psychotherapy after discharge from a clinic for psychosomatic medicine and psychotherapy. Nearly 8 % of them utilized self-help groups (mostly combined with out-patient psychotherapy), and altogether 68 % out-patient psychotherapy following in-patient treatment. Patients without out-patient treatment were psychologically less burdened and had better resources than participants of self-help groups or psychotherapy. Self-help group members differed from patie…

Inter-society consensus document on treatment and prevention of bronchiolitis in newborns and infants

2014

Acute bronchiolitis is the leading cause of lower respiratory t ract infection and hospitalization in children less than 1y ear of age worldwide. It is usually a mild disease, but some children may develop severe symptoms, requiring hospital admission and ventilatory support in the ICU. Infants with pre-existing risk factors (prematurity, bronchopulmonary dysplasia, congenital heart diseases and immunodeficiency) may be predisposed to a severe form of the disease. Clinical diagnosis of bronchiolitis is manly based on medical history and physical examination (rhinorrhea, cough, crackles, wheezing and signs of respiratory distress). Etiological diagnosis, with antigen or genome detection to i…

Varicella vaccination as useful strategy for reducing the risk of varicella-related hospitalizations in both vaccinated and unvaccinated cohorts (Ita…

2020

The present study summarizes evidences of the impact that varicella vaccination (VV) introduction and coverage can have on varicella attributable hospitalization rates.A retrospective observational study was carried out by considering hospital discharge records and VV coverage at 24 months collected from 2003 to 2018 by the Italian Ministry of Health. All hospitalizations records reporting an ICD-9 CM 052.X code as the principal diagnosis or any of the five secondary diagnoses were considered as related to varicella. The hospitalization rate reduction was evaluated by calculating average annual percent change (AAPC) through joint-point analysis.Hospitalization rates showed a decreasing tren…
