Psychometric Properties of the Scoliosis Research Society Questionnaire (Version 22r) Domains Among Adults With Spinal Deformity : A Rasch Measuremen…
2022
Objective: Adults with degenerative spinal deformity (ASD) have lower health-related quality of life (HRQL) compared to the general population. Applying Rasch Measurement Theory (RMT), this study tested the revised Scoliosis Research Society-22 (SRS-22r) HRQL instrument among symptomatic adult patients with degenerative spinal disorders and varying degrees of ASD. Methods: SRS-22r data from 637 outpatient spine clinic patients with degenerative spine conditions were investigated for unidimensionality, item/scale fit, differential item functioning (DIF), scale coverage/targeting, and person separation index (PSI) using RMT. Results: Unidimensionality of the SRS-22r was not supported for eith…
Sleep Disturbances in COPD are Associated with Heterogeneity of Airway Obstruction
2018
Individuals with Chronic Obstructive Pulmonary Disease (COPD) experience sleep disturbances due to the impact of respiratory symptoms on sleep quality. We explored whether sleep disturbances in COPD are linked to heterogeneity of airway constriction.The impact of breathing problems on sleep quality was measured in consecutive COPD outpatients with the COPD and Asthma Sleep Impact Scale (CASIS) questionnaire. Impulse oscillometry technique (IOS) was employed to assess heterogeneity of airway constriction. Subjects with a previous or concomitant diagnosis of asthma or obstructive sleep apnea (OSA) were excluded.Fifty COPD subjects (M/F 40/10; age: 71 +/- 8 yrs, Body Mass Index (BMI): 26.2 +/-…
Cognitive behavioural therapy interventions for insomnia among shift workers: RCT in an occupational health setting
2019
Abstract Introduction The aim of the study was to compare the effectiveness of cognitive behavioural therapy interventions for insomnia (CBT-I) to that of a sleep hygiene intervention in a randomized controlled design among shift workers. We also studied whether the features of shift work disorder (SWD) affected the results. Methods A total of 83 shift workers with insomnia disorder were partially randomized into a group-based CBT-I, self-help CBT-I, or sleep hygiene control intervention. The outcomes were assessed before and after the interventions and at 6-month follow-up using questionnaires, a sleep diary, and actigraphy. Results Perceived severity of insomnia, sleep-related dysfunction…
Excessive Daytime Sleepiness in Obstructive Sleep Apnea Patients Treated With Continuous Positive Airway Pressure: Data From the European Sleep Apnea…
2021
Excessive daytime sleepiness (EDS) is a symptom of obstructive sleep apnea (OSA) that resolves under treatment with continuous positive airway pressure (CPAP). In some patients, sleepiness persists despite CPAP treatment. We retrospectively analyzed data on subjective residual EDS, assessed as an Epworth Sleepiness Scale score (ESS) >10, in patients from the European Sleep Apnea Database (n = 4,853, mean age +/- SD 54.8 +/- 11.8 years, 26.1% females), at baseline and at the first visit (median follow-up: 5 months, interquartile range 3-13). An ESS > 10 occurred in 56% of patients at baseline and in 28.2% of patients at follow-up. Residual EDS was analyzed in 2,190 patients (age: 55.1 +/- 12…

A fluorescence study of the loading and time stability of doxorubicin in sodium cholate/PEO-PPO-PEO triblock copolymer mixed micelles
2019
Abstract Hypothesis Doxorubicin hydrochloride (DX) is one of the most powerful anticancer agents though its clinical use is impaired by severe undesired side effects. DX encapsulation in nanocarrier systems has been introduced as a mean to reduce its toxicity. Micelles of the nonionic triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (PEO-PPO-PEO), are very promising carrier systems. The positive charge of DX confines the drug to the hydrophilic corona region of the micelles. The use of mixed micelles of PEO-PPO-PEO copolymers and a negatively charged bile salt should favour the solubilization of DX in the apolar core region of the micelles. Experiments We st…
Sports teams as complex adaptive systems: manipulating player numbers shapes behaviours during football small-sided games
2016
Small-sided and conditioned games (SSCGs) in sport have been modelled as complex adaptive systems. Research has shown that the relative space per player (RSP) formulated in SSCGs can impact on emergent tactical behaviours. In this study we adopted a systems orientation to analyse how different RSP values, obtained through manipulations of player numbers, influenced four measures of interpersonal coordination observed during performance in SSCGs. For this purpose we calculated positional data (GPS 15 Hz) from ten U-15 football players performing in three SSCGs varying in player numbers (3v3, 4v4 and 5v5). Key measures of SSCG system behaviours included values of (1) players’ dispersion, (2) …
Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users
2018
Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…
Smart city: casi studio
2015
Il capitolo effettua un'ampia ricognizione delle smart city nel mondo, dagli esempi europei più noti alle smart city nelle città asiatiche. Da Masdar negli Emirati Arabi a Stoccolma, che in questi ultimi anni ha rigenerato con un'ottica smart interi quartieri (Hammarby Syostad e il Royal Seaport), cambiando complessivamente il volto della città. Il capitolo in questa terza edizione dedica un'attenzione speciale alle città asiatiche - la Cina ad esempio - che oggi si confrontano con profondi mutamenti socio-economici e imponenti e veloci fenomeni di urbanizzazione.
Palermo senziente. Città di persone e città di sensori
2021
Nel mondo contemporaneo, razionalità e percezione non nascono più nella mente e nei sensi umani. Un recente libro curato da Grazia Concilio e Francesca Rizzo mostra numerose sfaccettature di questa questione. Quando nel 2017 Maurizio Carta introduce il concetto di città senziente, rafforza significativamente le basi per integrare ragione e sentimento urbanistico, cioè per integrare la razionalità della conoscenza strutturata e finalizzata al processo di pianificazione con le percezioni derivanti dalla “pancia” della città. Il contributo propone una visione innovativa sulla dualità analitica e valutativa che si genera tra mondo reale e mondo digitale, tra gli abitanti-utenti delle città e gl…
