Reconstruction of critical-size mandibular defects in immunoincompetent rats with human adipose-derived stromal cells
2013
In patients with bony defects, autologous bone grafts are the "gold standard" for reconstruction. In children, autologous bone harvesting is limited but tissue engineering offers an alternative. Next to bone marrow, adipose tissue is a source of mesenchymal stromal cells, and adipose-derived stromal cells (ADSC) can differentiate into osteocytes. The aim of this study was to evaluate the efficacy of bioactive implants (ADSC in fibrin glue) for repair of critical-size mandibular defects in athymic rats. Human adult ADSC embedded in fibrin glue were implanted into a critical-size defect in the rat mandible and their efficacy was compared to those of protected bone healing (pbh), autologous bo…
The influence of parental modelling on children's physical activity and screen time: Does it differ by gender?
2016
Background: Parents play an important role in modelling healthy behaviours to their children. This study investigated associations between parent and child physical activity and screen time behaviours across specific domains, including moderating effects by parent and child gender. Method: The sample comprised 3300 school children and 2933 parents participating in the UP4FUN project (mean ages: child 11.2 ± 0.8 years, mother 40.0 ± 4.9 years, father 43.4 ± 5.8 years; 49% boys, 83% mothers). Data were collected in 2011 in Belgium, Greece, Hungary, Germany and Norway. Questionnaires assessed physical activity (sport, outdoor activities, walking and cycling for transport) and screen time (TV/D…
The Basic Psychological Need Satisfaction and Frustration Scale: Construct and Predictive Validity in the Italian Context
2020
The Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) is a self-report instrument assessing the satisfaction and frustration of the three basic psychological needs of autonomy, competence, and relatedness defined by self-determination theory. The aim of this study was to examine the dimensionality, the predictive validity, and the measurement invariance across different age groups of the Italian version of the BPNSFS. The participants were 2,204 Italian adolescents and young adults (41% males) from 14 to 28 years old (M age = 20.23, SD = 4.25). The invariance across age demonstrated adequate equivalence of the 6-factor model of scales across adolescents (14–18 years) and …
Development of a new measure for assessing insight: Psychometric properties of the insight orientation scale (IOS)
2015
Abstract Introduction Given the centrality of insight in promoting change, the relevance of measures for assessing this construct has become increasingly clear. This paper describes a new self-report measure for assessing some of the characteristics of insight, the insight orientation scale (IOS). Aims In study 1, we evaluated the factor structure and the reliability of the scale. In study 2, we analyzed the concurrent and discriminant validity of the scale in patients with different clinical diagnoses. Methods In study 1 participants were 600 individuals (41.1% male, 58.9% female) with a mean age of 33.95 years (SD = 13.04). In study 2 participants were 136 individuals divided into the fol…
Construction of quality of life change patterns: example in oncology in a phase III therapeutic trial (FFCD 0307)
2015
Objective Quality of life data in cancerology are often difficult to summarize due to missing data and difficulty to analyze the pattern of evolution in different groups of patients. The aim of this work was to apply a new methodology to construct Quality of Life (QoL) change patterns within patients included in a clinical trial comparing to regimen of treatment in locally advanced eosogastric cancer. Materials and methods In this trial, QoL was assessed every 2 months by self-reported EORTC QLQ-C30 questionnaire. Physical dimension scores were analyzed. After multiple imputation of missing data, 27 statistical measures aiming to describe the variation of QoL measures among follow-up were c…
Long-term outcome of patients with or without osseointegrated implants after resection of mandibular ameloblastoma and reconstruction with vasculariz…
2018
BACKGROUND: The optimal management after the resection of mandibular ameloblastoma has been very challenging to surgeons. The aim of this study is to evaluate the functional, aesthetic, and quality of life outcomes of patients who had a segmental mandibular resection and immediate reconstruction with or without osseointegrated implants. METHOD: Patients' demographics, tumor characteristics, treatment, and complications were retrieved. Patients were divided into two groups: dental rehabilitated vs. nondental rehabilitated depending on the placement of osseointegrated implants followed by an implanted-retained prosthesis. Functional outcomes and quality of life were assessed using the Perform…
The role of novelty detection in food memory
2010
International audience; Memory plays a central role in food choice. Recent studies focusing on food memory in everyday eating and drinking behaviour used a paradigm based on incidental learning of target foods and unexpected memory testing, demanding recognition of the target among distractors, which deviate slightly from the target. Results question the traditional view of memory as reactivation of previous experiences. Comparison of data from several experiments shows that in incidentally learned memory, distractors are rejected, while original targets are not recognised better than by chance guessing. Food memory is tuned at detecting novelty and change, rather than at recognising a prev…
Retrospective Analysis in Lower Limb Reconstruction: Propeller Perforator Flaps versus Free Flaps.
2017
Background Technical advancements and increasing experience in the management of soft tissue defects in lower extremities have led to the evolution of decisional reconstructive algorithms. Both propeller perforator flaps (PPFs) and free flaps (FFs) proved to be useful methods of reconstruction for lower extremities defects, offering alternative reconstructive tools. We present a case series of PPFs and FFs for reconstruction of lower limbs defects, analyzing and comparing treatment and outcomes. Methods Through a retrospective analysis, we report our experience in performing PPFs or FFs for reconstruction of soft tissue defects of the lower extremities, in patients admitted between 2010 an…
Prophylactic chimera anterolateral thigh/vastus lateralis flap: preventing complications in high-risk head and neck reconstruction
2014
Purpose In high-risk head and neck cases treated with tumor resection and associated radical neck dissection, orocutaneous fistulas and wound breakdowns in the neck are relatively frequent and can have serious consequences, such as carotid blowout syndrome (CBS), the need for salvage reoperations, and prolonged recovery time. The authors present the application of a prophylactic chimeric anterolateral thigh (ALT) and vastus lateralis (VL) flap to prevent complications. Materials and Methods A retrospective review was performed of a historical group (96 patients) of patients with head and neck cancer treated with tumor resection, radical neck dissection, and microsurgical reconstruction of t…
Knowledge and training needs on built environment and indoor health of Italian public health residents: a national survey
2017
Introduction The Working Group for Hygiene of Built Environment and the National Council of Residents of the Italian Society of Hygiene, Preventive Medicine and Public Health conducted a nation-wide survey to evaluate the knowledge and training needs on built environment and indoor health of Italian public health residents. Results The compliance was very high (52,4%) covering all the Italian postgraduate schools. The results underline important lacks of theoretical formation and practical training, but also a certain inhomogeneity across the country and show a strong interest of residents on this topic. Conclusions The authors propose the adoption a national core curriculum and suggest som…
