    Opis:
    This study presents the results of the design and characterization of a gas sensor with PMMA/CNTs chemiresistor as sensing element for detection of organic vapors. Multi wall carbon nanotubes (MWCNTs) produced at our lab (by method of pyrolysis, outer diameter d=10÷40 nm, purity ≈94%) were incorporated into biocompatible polymer matrix. Poly(methyl methacrylate) - PMMA - and nanocomposite films were obtained using casting solution technique. Produced nanocomposite films were investigated with thermogravimetric analysis, differential scanning calorimetry, X-ray analysis, scanning electron microscopy, and Fourier transform infrared, while the sensors activity was determined by the changes in electrical resistance of the nanocomposite films due to acetone and chloroform exposure. The response to these vapors was evaluated and it was shown that PMMA/MWCNTs composites exhibit changes in electroresistivity. Sensitivity was calculated to be in 0.58-54.6 range (30 min exposed to acetone) and 0.53-10.35 (30 min exposed to chloroform). The results presented in this paper show that CNTs are able to improve the overall performances of polymer based sensors.

    Opis:
    The subject of this study is chemical functionalization as means of structural modification of multiwalled carbon nanotubes. The main goal of the experiments was to create highest density of carboxyl groups on multiwalled carbon nanotubes surface, necessary for further nanocomposite application. Two different types of multiwalled carbon nanotubes (I: outer diameter d=50÷ 100 nm, purity ≈84%, synthesized by pyrolysis and II: outer diameter d=10÷40 nm, purity ≈94%, synthesized by chemical vapor deposition) were treated by concentrated nitric acid (HNO₃) and by alkaline mixture (NH₄OH+H₂O₂). The alkaline medium as "milder" and less aggressive than nitric acid, was expected to be less destructive and cause minimal structural damage on multiwalled carbon nanotubes surface. Structural changes due to oxidation were observed by the Raman analysis, while the ratio of the intensities of the D and G peak was used to estimate the concentration of defects. Pristine and functionalized multiwalled carbon nanotubes were characterized by thermogravimetric analysis, scanning electron microscopy, ultraviolet-visible spectroscopy and zeta (ζ) spectroscopy. The results showed that functionalization initiates changes in carbon nanotubes structure as well as in their density of states. It also results in carbon nanotubes shortening and exfoliation and decreases their agglomeration tendency. Carbon nanotubes functionalized by both acid and alkaline treatment can successfully replace conventional carbon fibers as fillers in polymer composites for sensing application.

    Opis:
    Objectives To investigate the prevalence of obesity among different types of employment status in the Italian working population, and to examine associated risk factors. Material and Methods Cross-sectional survey of 36 814 people that declared to have been occupied with the same type of contract for at least 5 years was analyzed. Multivariable logistic regression models were built considering workers’ sex, age, education, family body mass index (BMI) category, leisure time and occupational physical activity, weight control habits, smoking habit, use of drugs, number of working hours per week, and type of working contract. Results After adjusting for covariates, the importance of temporary-employment was confirmed by multivariate analysis, with odds ratio (OR) = 1.32 for obesity (95% confidence interval (CI): 1.07–1.63) with respect to employed persons; the association was even more important in workers occupied for more than 40 h/week (OR = 1.69, 95% CI: 1.07–2.66); moreover, shiftwork was confirmed as a risk factor for obesity in workers (OR = 1.06, 95% CI: 0.94–1.2). Dealing with different occupational group, some categories were associated with obesity; in particular, this phenomenon involved people employed in agriculture (OR = 1.44, 95% CI: 1.22–1.7), transportation (OR = 1.53, 95% CI: 1.26–1.85), and public administration (OR = 1.31, 95% CI: 1.1–1.55). Conclusions Our analysis suggest that obesity is strongly correlated with temporary employment. Maybe the way out this pathway to obesity in the future might be working better, choosing organizational flexibility rather than fixed term. Int J Occup Med Environ Health 2016;29(6):903–914

    Opis:
    Consumer and system-wide gains remain limited by an outmoded policy regime. With scientific innovation running far ahead of public policy, physicians, researchers and patients are not receiving full advantage of the latest developments. European health systems require a seamless and rapid flow of digital information, including genomic, clinical outcome, and claims data. Research derived from clinical care must feed back into assessment, in order to advance care quality for consumers. National health systems are heterogeneous; the solutions and required fundamental approaches differ between the European member states and are not entirely portable and scalable. To date, this applies not only to general systemic aspects but particularly to cross-border reimbursement issues and the exchange of treatment and patient data. To answer those needs, an international consortium was established to implement the project “Interregional coordination for a fast and deep uptake of personalised health”: Regions4PerMed. A cycle of international events, such as conferences, in situ visits and workshops, has been planned. Interdisciplinary groups of experts will exchange thoughts and experiences to design solutions that could be implemented in the various healthcare systems. Regions4PerMed aims to coordinate regional policies and innovation programmes in personalised medicine and personalised health to accelerate the deployment of personalised health for patients. Key Action 2 is dedicated to health technologies and smart and integrated care.

    Opis:
    Personalised medicine (PM) represents a paradigm shift away from the ‘one size fits all’ approach to the treatment and care of patients with a particular condition, to one which uses emergent technologies such as diagnostic tests, functional genomic technologies, and molecular pathway profiling to better manage patients’ health and employ target therapies. The current challenge for national and regional authorities is to facilitate the shift from a reactive healthcare system based on episodic and acute care models to a personalized health (PH) system that uses preventive and predictive measures, where at-risk individuals are stratified to intervene before the onset of symptoms or risk is predicted using cutting-edge technologies before symptoms appear. While PH is paving the way toward better and more efficient patient care, it still lacks the cooperation and coordination needed to organise the fragmented field, which is a severe drawback to its development and to the placement of effective financial investments. For this reason, it is crucial to direct major efforts towards coordinating and aligning relevant stakeholders across Europe and beyond, creating a participatory approach, building trust, enabling a multi-stakeholder process, and channeling investments towards PH. Thus, Regions4PerMed aims to coordinate regional policies and innovation programmes in PM and PH to accelerate the deployment of PH for patients.
