Uso delle resistenze specifiche per la stima della risposta al broncodilatatore in pazienti BPCO
No full textNei pazienti affetti da broncopneumopatia cronica ostruttiva (BPCO), i broncodilatatori migliorano la funzione polmonare e alleviano la sintomatologia respiratoria nella misura in cui riducono la resistenza delle vie aeree durante la respirazione tidalica, prevenendo o riducendo l’iperinflazione dinamica (Barnes et al., 1981). Inoltre, la riduzione del tono broncomotore a livello delle piccole vie aeree può ridurre il volume residuo (RV) e aumentare la capacità vitale (VC).
Secondo le linee guida ATS/ERS (Pellegrino et al., 2005), un paziente BPCO risponde a un broncodilatatore se, dopo somministrazione del farmaco, l’aumento del volume espirato forzatamente in un secondo (FEV1) e/o della capacità vitale forzata (FVC) è uguale o maggiore del 12% del valore di controllo, e comunque uguale o maggiore di 200 ml.
Tuttavia è noto che a) FEV1 riflette solo parzialmente le resistenze polmonari (Pride, 1971;Skinner and Palmer, 1974), b) la misurazione di FEV1 e di FVC è ottenuta con una manovra di per sè in grado di modificare il calibro delle vie aeree (Barnes et al., 1981), c) FEV1 e FVC sono altamente correlate (Schermer et al., 2007), e d) le variazioni di FEV1 e di FVC nei pazienti BPCO di grado severo possono essere molto piccole (Deesomchok et al., 2010).
E’ possibile che le variazioni delle resistenze specifiche pletismografiche (sRAW), un parametro che riflette accuratamente le resistenze delle vie aeree periferiche (Bassiri et al., 1997), possano evidenziare l’azione dei broncodilatatori nei pazienti BPCO meglio di quanto possano fare le variazioni di FEV1 o di FVC
Indogenous agricultural products and biodiversity for the development of regional areas. Italy calls Bosnia and Herzegovina
No full textIn 1992, the Earth Summit in Rio de Janeiro considered "biological diversity" by introducing the term "agricultural biodiversity" or "agro-biodiversity", conceived as the set of varieties that each farmer recognizes and considers as part of the collective heritage of his land of origin. Italy holds a record of biodiversity for almost all the most important crops used for food, only partly due to physical and geographical factors. Apulia, in Southern Italy, is witnessed by numerous small details such as the countless units of land surface and quantity of agricultural products, the thousand dialects, habits and customs of the small towns. Apulia seems to be “a happy island” for biodiversity and needs to be protected with about 500 agricultural varieties between horticulture products and vegetables (“Polignano” carrots, onions from Acquaviva, and so on).
The Southern part of Bosnia and Hercegovina, region of Herzegovina, is administratively divided to Western and Eastern Hercegovina having Neretva river as natural border between two. Due to difficult post-conflict transitional period, disputable approaches undertaken in revitalization of the agriculture and ongoing political disagreements, the rich agro-biodiversity of the area has been partially lost. But regardless all difficulties, Herzegovina farmers, holding a strong cultural identity with food, helped saving from disappearance some of the oldest and most traditional products such as cheese in sack, kajmak (creamy cheese) in sack, “roga” green bean or “poljak” bean, all of them recognized by Slow Food movement to be “arc of taste” products.
The contribution, in addition to verifying the state of the art, intends to evaluate the different approaches regarding the subject outlined with regard to management and practices in Italy and in Bosnia and Herzegovina

No full textA safety, length of stay, and cost analysis of minimally invasive microsurgery for anterior circulation aneurysms
No full textObjectives: The aim of our study was to evaluate minimally invasive techniques for the treatment of anterior circulation aneurysms versus standard surgery, and to calculate the impact of these techniques on health resources, length of stay, and treatment costs. Methods: A consecutive series of 24 patients with ruptured and 30 with unruptured anterior circulation aneurysms treated with minimally invasive microsurgery (MIM) by the same surgeon was compared with a matched series of standard microsurgeries (SM) conducted for 23 ruptured and 22 unruptured aneurysms. Complication rates, aneurysm obliteration, modified Rankin Scale (mRS) outcomes, length of stay, and treatment costs were assessed. Results: Surgical complications, aneurysm obliteration rates and mRS outcomes were comparable between MIM and SM groups in ruptured and unruptured aneurysm cohorts. MIM resulted in shorter operative times both in unruptured (102.7 ± 4.35 vs 194.7 ± 10.26 min, p < 0.0001) and ruptured aneurysms (124.3 ± 827 vs 209 ± 13.84 min, p < 0.0001). Length of stay was reduced in patients with MIM for unruptured aneurysms (1.55 ± 24 vs 4.28 ± 0.71 days, p < 0.000,1) but not in those with ruptured aneurysms. MIM reduced treatment costs of unruptured aneurysm patients, mainly through reduced utilization of inpatient resources (non-acute bed costs in CAD: 371.2 ± 80.99 vs 1440 ± 224.1, p < 0.0001), whereas costs were comparable in patients with ruptured aneurysms. Conclusion: Minimally invasive surgery is a safe and effective approach for the treatment of ruptured and unruptured aneurysms of the anterior circulation. In patients with unruptured aneurysms, reduced invasiveness and shorter operative times decreased length of stay, which reflects improved patient postoperative recovery. Overall, this translated into bed resource economy and cost reduction. © 2014 Springer-Verlag Wien
Tiotropium: what came after the UPLIFT study
No full textINTRODUCTION: Chronic obstructive pulmonary disease (COPD) is characterized by a progressive bronchial obstruction, and bronchodilators represent the maintenance therapeutic choice. Tiotropium is an anticholinergic drug that is proved to be safe, efficient and simple to handle; Respimat® technology was recently introduced as a new device for tiotropium administration. AREAS COVERED: This paper reviews clinical trials and meta-analyses, with tiotropium efficacy as a primary end point, found in MedLine, the Cochrane trials database and Embase. Only the literature published after the UPLIFT study has been considered. EXPERT OPINION: Data published after the UPLIFT study confirms the efficacy of tiotropium as maintenance COPD therapy and its capacity to reduce airflow obstruction, as well as lung hyperinflation. Nevertheless, there is a certain inhomogeneity in the definition and evaluation of COPD exacerbations, in lung functional parameters and quality-of-life assessment, and there has not always been a proper comparison between tiotropium and other long-acting bronchodilators. Respimat is comparable in efficacy to the HandiHaler®, using bioequivalent doses of tiotropium
Using numerical simulation in the optimization of the finishing phases in ceramic tiles manufacturing
No full textThe Grés Porcelain stoneware surely represents a remarkable material for building inside the large family of constructive ceramics. It is appreciated in consideration of its superior properties of resistance and functionality, especially when considered respect to a relatively low cost. Billions of square meters of Grés Porcelain are produced worldwide each year, primarily in form of tiles of every dimension, thinness, color, decoration, in the way that the ceramic tile industry represents a relevant economy. But the tile manufacturing is a complex process, made by different stages and productive plants to be deeply investigated and optimized. This paper describes the use of Finite Elements for modelling and optimizing the production of Grés Porcelain tiles with special attention to the ending phases of the process, just after the treatments in kiln and realized by tool machining. The case study, used to redesign a fundamental part of a finishing machine driven by a numerical approach, is also detailed
Manipulation of Conducting Oxides and Their Rational Design for Use in Photonics
No full textTransparent conducting oxides (TCOs) have been largely studied for their applications in light emitting diodes (LEDs), photodetectors, solar cells, and other photonic uses. TCOs are useful as they can be doped or alloyed to tune specific properties such as photoluminescence (PL), allowing them to emit light spanning the entire visible region or near UV. Considering literature and research from the Radovanovic group, the TCO gallium (III) oxide (Ga2O3) and cerium oxide (CeO2) were selected to be modified via doping, alloying and surface treatments to design functional nanoparticles (NPs). Cerium oxide nanoparticles (CNPs) were synthesized with varying surface modifiers to enhance their UV emission. Low temperature PL data of tri-octylphosphine oxide (TOPO) surface treated CNPs reveal a novel UV emission theorized to originate from the charge transfer (CT) between Ce3+ and TOPO ligands, and Ce3+ intracentre transitions (5d-4f). Lanthanides were then introduced into the CNPs as dopants to further functionalize CNPs. Erbium cerium oxide NPs demonstrated a novel white light emission, that could be useful in future white LED applications. Functionalization of CNPs by lanthanide incorporation is also explored through sensitization of Tb3+ ions. The synthesis of γ-gallium oxide (γ-Ga2O3) is also studied herein, and several synthesis parameters were tuned. Aluminum will be used as an alloying species because aluminum oxide (Al2O3) can form a defective spinel lattice structure like γ-Ga2O3 allowing it to easily form an alloy structure. Al2O3’s larger band gap energy allows band gap manipulation in alloyed aluminum gallium oxides (AGOs) NPs. The results indicate an increase in band gap energy and an emission shift to the UV region as aluminum concentration is increased. Overall, the results found herein the thesis demonstrate the use of rational design and nano-engineering to achieve novel and useful metal oxide NPs for potential applications in photonics and beyond
