Sistema Integrato Multicentrico di Indicatori. Rapporto 2005. Provincia di Potenza
The SIMI (Integrated System of Indicators multicenter) Project contributes to the development of an integrated management of informative data streams related to drug addicted persons. This report analyzes the phenomenon of addiction on the territory of Potenza province through a description of the network services that provide care and rehabilitation of those addicted. Besides the characteristics of users of local services for addictions, has been developed the analysis of the subjects reported to the prefectures for use of illegal drugs and any action taken. Standard methods of estimation were also applied to quantify the proportion of users of substances that do not relate to services and to identify certain characteristics.Il Progetto SIMI (Sistema Integrato Multicentrico di Indicatori) intende contribuire allo sviluppo di una gestione integrata e sinergica dei flussi informativi relativi ai consumatori di sostanze stupefacenti afferenti alle diverse amministrazioni dello Stato. In linea con quanto proposto dall\u27Osservatorio europeo di Lisbona, per la descrizione e analisi del fenomeno connesso all\u27uso/abuso di sostanze, risulta di fondamentale importanza la possibilit? di ottenere informazioni esaustive e comparabili sulle persone che usano e/o abusano di sostanze psicotrope. Il presente rapporto analizza il fenomeno delle dipendenze sul territorio della provincia di Potenza attraverso la descrizione della rete dei servizi preposti alla cura e riabilitazione dei soggetti tossicodipendenti. Accanto alle caratteristiche degli utenti dei servizi territoriali per le dipendenze, ? stata sviluppata l\u27analisi dei soggetti segnalati alle Prefetture per uso di sostanze illegali e degli eventuali provvedimenti adottati. Sono state inoltre applicate metodologie standard di stima per quantificare la quota parte di utilizzatori di sostanze che non afferiscono ai servizi e per identificarne alcune caratteristiche
A Systematic Review and International Web-Based Survey of Randomized Controlled Trials in the Perioperative and Critical Care Setting: Interventions Reducing Mortality
The authors aimed to identify interventions documented by randomized controlled trials (RCTs) that reduce mortality in adult critically ill and perioperative patients, followed by a survey of clinicians’ opinions and routine practices to understand the clinicians’ response to such evidence. The authors performed a comprehensive literature review to identify all topics reported to reduce mortality in perioperative and critical care settings according to at least 2 RCTs or to a multicenter RCT or to a single-center RCT plus guidelines. The authors generated position statements that were voted on online by physicians worldwide for agreement, use, and willingness to include in international guidelines. From 262 RCT manuscripts reporting mortality differences in the perioperative and critically ill settings, the authors selected 27 drugs, techniques, and strategies (66 RCTs, most frequently published by the New England Journal of Medicine [13 papers], Lancet [7], and Journal of the American Medical Association [5]) with an agreement ≥67% from over 250 physicians (46 countries). Noninvasive ventilation was the intervention supported by the largest number of RCTs (n = 13). The concordance between agreement and use (a positive answer both to “do you agree” and “do you use”) showed differences between Western and other countries and between anesthesiologists and intensive care unit physicians. The authors identified 27 clinical interventions with randomized evidence of survival benefit and strong clinician support in support of their potential life-saving properties in perioperative and critically ill patients with noninvasive ventilation having the highest level of support. However, clinician views appear affected by specialty and geographical location

Structure of low-order hemimorphite produced in a Zn-rich environment by cyanobacterium Leptolingbya frigida
Microbes play a fundamental role in the precipitation of silicate biominerals, thereby affecting the Si geochemical cycle. The fne mechanisms ruling biomineralization are not yet fully understood, and their microscopic structures can offer deep insight into their processes of formation, reactivity and stability. In this study, a Zn silicate biomineral, extracellularly produced by cyanobacterium Leptolingbya frigida, was investigated combining nuclear magnetic resonance (NMR), Zn K-edge X-ray absorption spectroscopy (XAS) and other complementary techniques. 29Si magic angle spinning and 29Si/1H cross polarization magic angle spinning analysis, Fourier transform infrared spectroscopy (FTIR) and XAS analysis revealed a poorly crystalline phase closely resembling hemimorphite [Zn4Si2O7(OH)2•H2O]. Zn K-edge extended X-ray absorption fne structure (EXAFS) provided further structural details, revealing that the Zn-O-Si interatomic distances were 7-8% shorter than the abiotic mineral. 13C NMR spectra analysis was conducted to investigate the composition of the Zn silicate biomineral organic matrix, and results revealed that C atoms occurred in several functional groups such as carbonyl carbons, C rings, O-aliphatic chains, N-aliphatic chains, and aliphatic chains. Under slightly alkaline conditions, bacterial cell walls exhibited fundamental control on the biomineralization process by binding Zn ions and forming Zn-O-Si bonds. In this way, L. frigida cell walls served as a reactive surface for the precipitation of this Zn sorosilicate, hindering the condensation of silicon dimers. Moreover, we found a 29Si NMR band at 85 ppm that could be attributed to a (C3H6O3)2Si complex. This complex could play a role in the control of silicon polymerization, with implications for Si biomineralization processes
