Assessing preoperative anxiety using a questionnaire and clinical rating

2013

Background Preoperative anxiety and need for information can be detected during preoperative consultation via structured and standardised screening by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaire. Objective To identify the prevalence of preoperative anxiety and need for information, with regard to influencing factors such as age, sex, previous operation and grade of surgery, and to examine the level of agreement between patients' self-rating and physicians' ratings. Design Prospective observational study. Setting Department of Anaesthesiology, University Medical Centre of the Johannes Gutenberg University Mainz, Germany. Patients Two hundred seventeen patie…

Assessing psychological and supportive care needs in glioma patients - feasibility study on the use of the Supportive Care Needs Survey Short Form (S…

2016

Neuro-oncological patients experience high symptom and psychosocial burden. The aim was to test feasibility and practicability of the Supportive Care Needs Survey Short Form (SCNS-SF34-G) and the SCNS-Screening Tool (SCNS-ST9) to assess supportive care needs of neuro-oncological patients in clinical routine. A total of 173 patients, most with a primary diagnosis of high-grade glioma (81%), were assessed first using SCNS-SF34-G in comparison to two well-established patient-reported outcome measures, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQC30 + QLQ-BN20) and Distress Thermometer (DT). In a follow-up assessment, SCNS-ST9 was used …

Results of an orthopaedic survey in young patients with severe haemophilia in Spain

2002

Summary.  This paper outlines the results obtained in a cross-sectional study of a group of young patients with severe haemophilia A and B. The primary aim of the study was to ascertain the level of orthopaedic complications in the group, the effects that these complications have on quality of life, and the medical resources used on these patients. The secondary aim was to relate their current orthopaedic state to the type of treatment received before the study. The study was carried out in 11 hospitals in Spain, where 70 severe haemophilia patients (factor VIII [FVIII] < 2%), with an average age of 21.6 and a median age of 22, and no inhibitors, were monitored. The percentage of patients s…

VO2max Characteristics of Elite Female Soccer Players, 1989–2007

2013

Purpose:To quantify VO2max among female competitive soccer players as a function of performance level, field position, and age. In addition, the evolution of VO2max among world-class players over an 18-y period was quantified.Methods:Female players (N = 199, 22 ± 4 y, 63 ± 6 kg, height 169 ± 6 cm), including an Olympic winning squad, were tested for VO2max at the Norwegian Olympic Training Center between 1989 and 2007.Results:National-team players had 5% higher VO2max than 1st-division players (P = .042, d = 0.4), 13% higher than 2nd-division players (P &lt; .001, d = 1.2), and 9% higher than junior players (P = .005, d = 1.0). Midfielders had 8% higher VO2max than goalkeepers (P = .048, d …

Threshold rule and scaling behavior in a multi-agent supply chain

2010

In this paper an agent-based model of self organized criticality is developed in a network economy characterized by lead time and a threshold behavior of firms. Instead of considering the aggregate production of the economy as a whole, we focus on both the propagation and amplification effects of a demand shock in the sectorial productions of a multi-agent supply chain. We study a static network structure representing a relation of firms in a lower-upper stream in an industrial organization. In our model, the individual (R, nQ) policies play an important role in generating a propagation effect across the different layers of the economy, and the propagation turns into the large fluctuations …

An agent-based model to support the preliminary design and operation of heating and power grids with cogeneration units and photovoltaic panels in de…

2022

The increase in the energy demands of residential neighborhoods constitutes a huge challenge to be faced. A viable option lies in the insertion of both renewable energy production systems and cogeneration units within urban territories. On-site production allows for the satisfaction of the heating and electrical demands of end-users and favors the distribution of produced energy within the neighborhood, especially under the regulatory framework of energy communities. This paper proposes a tool to model heating and electricity networks integrated with cogeneration units and PV panels installed in urban areas. The tool accounts for the following possibilities: (i) energy flow management and p…

Consumers of flowers and ornamental plants: an eploratory survey in the Italian «Mezzogiorno» regions

2010

This paper aims to provide further knowledge of purchase and consumption behaviours with regard to flowers and ornamental plants in the regions of Italian «Mezzogiorno», as an acknowledgement of the centrality of final demand in the chain process. The knowledge of consumption process is fundamental either to the firm – in order to improve commercial strategies – or to competition authorities – with the purpose of implementing more effective policies. From the analysis carried out it emerges that flowers and ornamental plants consumption in the «Mezzogiorno» regions is characterised by a high penetration index and – just with regard to some commodities – by a low purchase frequency. Purchase…

Aspen Plus process-simulation model: Producing biogas from VOC emissions in an anaerobic bioscrubber

2018

A process-simulation model for a novel process consisted of an anaerobic bioscrubber was developed in Aspen Plus®. A novel approach was performed to implement the anaerobic reactor in the simulation, enabling it to be connected to the scrubber. The model was calibrated and validated using data from an industrial prototype that converted air emissions polluted with volatile organic compounds with an average daily concentration of 1129 mgC Nm−3 into bioenergy for more than one year. The scrubber, which showed a removal efficiency within 83-93%, was successfully predicted with an average absolute relative error of 5.2 ± 0.08% using an average height-to-theoretical-plate value of 1.05 ± 0.08 m …

Survey on the demand of sicilian physicians for a specific training on human cadavers and animals

2018

Currently, surgical training of physicians in Italy has limited possibilities.Surgical training can be performed on dissection of human bodies as well as in animal laboratories, but experience is very poor. We conducted a survey through an anonymous questionnaire in order to evaluate the opinions of post-graduate physicians on their need for experience training on both human and animal bodies during their medical studies. A total of 165 young Sicilian physicians responded to the survey. Only 14 of them (8.5%) declared they had specific training on a live animal, while 46 (27.9%) reported they already attended cadaver labs. Over 70% assigned the maximum score to the utility of such courses a…
