Item response theory and differential test functioning analysis of the HBSC-Symptom-Checklist across 46 countries
2022
Abstract Background The Symptom Checklist (SCL) developed by the Health Behaviour in School-aged Children (HBSC) study is a non-clinical measure of psychosomatic complaints (e.g., headache and feeling low) that has been used in numerous studies. Several studies have investigated the psychometric characteristics of this scale; however, some psychometric properties remain unclear, among them especially a) dimensionality, b) adequacy of the Graded Response Model (GRM), and c) measurement invariance across countries. Methods Data from 229,906 adolescents aged 11, 13 and 15 from 46 countries that participated in the 2018 HBSC survey were analyzed. Adolescents were selected using representative s…
Inverse Analysis Used to Determine Plastic Flow and Tribological Characteristics for Deep-drawing Sheet
2014
Abstract The present paper aims to develop a simple method based on inverse analysis that allows us to determine the laws of plastic flow coefficients and the friction coefficient between the material and punch. Selecting from different types of tests, we have chosen the Hecker test, because this test requires a single form of punch, the hemispherical one. In this test, the friction between the punch and the blank-sheet is caused by the blank-sheet strains and not by the movement it makes (as in deep drawing case). Besides the friction coefficient, other parameters like hardening and strength coefficients (n and k), influence the distribution of stresses and strains in the material. Using t…
What matters to older adults? Exploring person‐centred care during and after transitions between hospital and home
2021
Aims and objectives To explore person-centred care provided to a group of older adults (65+) by understanding their experiences of care received, their participation in care and what matters to them during and after the transition process between hospital and home. Background Although facilitating person-centred care (PCC) has gained increasing importance globally over the last few decades, its practical implementation has been challenging. This has caused difficulties in determining its core elements and best practices. Person-centred care aims to deliver healthcare services based on individuals' preferences. Several approaches have been developed to better implement person-centred care pr…
Health-related quality of life (HRQOL) in patients (pts) with advanced gastric cancer/gastroesophageal junction cancer (GC/GEJC) or esophageal adenoc…
2021
4066 Background: CheckMate 649 (NCT02872116) is a randomized, open label phase 3 study in first line (1L) GC/GEJC/EAC. Prespecified interim results showed statistically significant improvement in overall survival (OS) and progression-free survival (PFS) for N+C vs C in all randomized pts and pts whose tumors expressed programmed death-ligand 1 combined positive score (CPS) ≥ 5. We present interim HRQOL results for CPS ≥ 5 pts, included as exploratory in the study. Methods: HRQOL was assessed using EQ-5D-3L (EQ-5D) and Functional Assessment of Cancer Therapy–Gastric Cancer (FACT-Ga). Assessments were performed at baseline (BL), every 6 weeks during treatment, and during follow-up. Change fr…

First-Line Immune Checkpoint Inhibitor-Based Sequential Therapies for Advanced Hepatocellular Carcinoma: Rationale for Future Trials
2021
<b><i>Introduction:</i></b> Atezolizumab (ATEZO) plus bevacizumab (BEVA) represents the new standard of care for the treatment of advanced hepatocellular carcinoma (HCC). However, the choice of the second-line treatment after the failure of immunotherapy-based first-line remains elusive. Taking into account the weaknesses of the available evidence, we developed a simulation model based on available phase III randomized clinical trials (RCTs) to identify optimal risk/benefit sequential strategies. <b><i>Methods:</i></b> A Markov model was built to estimate the overall survival (OS) of sequential first- and second-line systemic treatments. Seque…
Caring by Telecare? A Hermeneutic Study of Experiences among Older Adults and Their Family Caregivers
2018
Aims and objectives To obtain a deeper understanding of the persistent use of telecare for older adults and their family caregivers. Background Telecare is seen as part of the solution in home care services for ageing in place. Previous studies have shown that telecare is a complex intervention, and there is still a poor understanding of older adults' and their family caregivers' experience with the use of telecare. Design This study used a qualitative hermeneutic research approach. Method Interviews were conducted with 18 older adults and follow-up interviews were conducted with 15 participants after 5-6 months of use. In addition, interviews were conducted with seven close family caregive…
Catechol-Functionalized Carbon Nanotubes as Support for Pd Nanoparticles
2022
Carbon nanotubes have been covalently functionalized with catechol moieties through the formation of the corresponding aryl radicals obtained by reacting 4-aminocatechol with isoamyl nitrite. The functionalized multiwalled carbon nanotubes have been in turn used to immobilize Pd(II) ions on its surface forming catechol-Pd complexes, which were reduced to Pd nanoparticles (NPs). The so-obtained hybrid material has been characterized by means of thermogravimetric analysis coupled with differential scanning calorimetry (TGA-DSC), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). This latter technique allowed to estimate the nanoparticle size (5.7 +/- 2.8 nm) wh…
Fact checking during COVID-19: a comparative analysis of the verification of false contents in Spain and Italy
2021
With the spread of COVID-19 around the world, a large number of hoaxes or false and out of context news are also spreading. In the moment, the studies that have been carried out regarding the topic have mainly focused on single-territory research. For this reason, we consider it pertinent to widen the spectrum and observe the behaviour of more than just one country. More specifically, the present study compiles a comparative analysis between Spain and Italy regarding fake contents and the diverse elements that have come into play in the media during the first months of the new type of coronavirus in Europe. To do this, we have used the fact checking platforms Maldita.es and Open. Once the i…
One hundred and fifty years of ornithology in Sicily, with an unknown manuscript by Joseph Whitaker
2021
A new complete check-list of Birds of Sicily is presented in this paper, with a comparison with previous lists for a period of one hundred and fifty years. Further, an unknown manuscript by Joseph Whitaker “Birds of Sicily”, dated back to ca. 1920, has been transcribed and is here presented integrally. Thus, lists of birds here presented have been separated as follows: i) Doderlein (1869–1874); ii) Whitaker (1920); iii) Iapichino & Massa (1989), Lo Valvo et al. (1993) iv) Corso (2005), Ientile & Massa (2008); v) 2010–2020: Massa et al. (2015) and personal observations; vi) long-term trend: personal observations. Overall, 437 species are listed. Out of 283 species regularly present i…
