PharmaCare 2018

[Italiano]: Il farmaco, nella sua accezione più ampia e generale, può essere ritenuto un bene sociale, la cui valenza simbolica e curativa varia in relazione alla dimensione ambientale e culturale nel quale si inserisce. In tal senso, le prescrizioni farmaceutiche rappresentano un indicatore privilegiato per la conoscenza del sistema salute di un determinato territorio, poiché costituiscono un punto di intersezione ideale tra la prospettiva medica e quella di mercato. Siffatte considerazioni hanno sollecitato l’elaborazione di questo Report che si pone, come obiettivi dichiarati, quello di essere uno strumento utile alla pianificazione di interventi di sanità pubblica, quanto quello di svolgere analisi approfondite sulle caratteristiche dei soggetti che usano i farmaci e sulle modalità di trattamento degli stessi, permettendo studi di appropriatezza prescrittiva su specifiche aree di rilevanza clinica e su specifiche coorti di soggetti. “PharmaCaRe Report 2018” è stato realizzato dal CIRFF (Centro Interdipartimentale di Ricerca in Farmacoeconomia e Farmacoutilizzazione) dell’Università degli Studi di Napoli Federico II, in collaborazione con la Direzione Generale della Tutela della Salute della Regione Campania, per delineare un quadro dettagliato circa il consumo e la prescrizione dei farmaci in Campania nel 2018. Questo Report intende infatti fornire una fotografia dettagliata dell’utilizzo che, in Campania, viene fatto dei farmaci in termini di spesa, volumi e tipologia. Le analisi dei dati prodotte offrono spunti importanti per correlare la prevalenza delle patologie nel territorio con il corrispondente utilizzo dei farmaci e suggeriscono un’interpretazione dei principali fattori che influenzano la variabilità nella prescrizione. La disponibilità di una banca dati che copre una popolazione assistibile di circa sei milioni di abitanti è d’altronde un potente strumento di ricerca per studiare gli effetti dell’utilizzo dei farmaci in condizioni di Real-World. La conoscenza delle dinamiche prescrittive, in termini qualitativi (appropriatezza d’uso), oltre che quantitativi (volumi di utilizzo) è la condizione necessaria per inquadrare in un contesto razionale la politica del farmaco, anche sotto il profilo della valutazione degli effetti degli interventi che il mercato, le normative o la cultura del farmaco sviluppano nel tempo. Per tali ragioni, “PharmaCaRe Report 2018” rappresenta un utile quanto prezioso supporto ai decisori per individuare strategie volte a ottimizzare l’allocazione delle risorse, nonché migliorare i percorsi di cura attraverso un monitoraggio costante, la promozione di più elevati standard di cura e l’uso sicuro, efficiente ed efficace dei farmaci ./[English]: In its broadest and most general sense, the drug can be considered a public resource, whose symbolic and curative value varies in relation to the environmental and cultural dimension in which it is embedded. In this sense, pharmaceutical prescriptions represent a privileged indicator for the knowledge of the health system of a given territory, since they constitute an ideal intersection point between the medical and the market perspective. Such considerations prompted the preparation of this Report. “PharmaCaRe Report 2018” has been produced by CIRFF (Centro Interdipartimentale di Ricerca in Farmacoeconomia e Farmacoutilizzazione) of the Federico II University of Naples, in collaboration with the Directorate-General for Health Protection of the Campania Region, to provide a detailed overview of the pharmaceutical consumption and prescriptions in Campania in 2018. This Report aims to provide a detailed picture of the use of medicines in the general population in Campania, in terms of expenditure, volumes and type. The analyses of the data produced offer important clues for correlating the prevalence of diseases in this area with the respective use of medicines and suggest an interpretation of the main factors influencing prescriptions' variability. The availability of a database covering a patient population of around six million is a powerful research tool for studying the effects of drug use in Real-World conditions. Knowledge of the dynamics of prescription, in qualitative terms (appropriateness of use), as well as quantitative (volumes of use) is the necessary condition to frame the drug policy in a rational context, also in terms of evaluating the effects of the interventions that the market, regulations or drug culture develop over time. For these reasons, “PharmaCaRe Report 2018” represents a useful and valuable tool for political decision-makers in identifying strategies aimed at optimizing the allocation of resources, as well as improving care pathways through constant monitoring, the promotion of higher standards of care and safe, efficient and effective use of drugs

Does Presentation Format Influence Visual Size Discrimination in Tufted Capuchin Monkeys (Sapajus spp.)?

Most experimental paradigms to study visual cognition in humans and non-human species are based on discrimination tasks involving the choice between two or more visual stimuli. To this end, different types of stimuli and procedures for stimuli presentation are used, which highlights the necessity to compare data obtained with different methods. The present study assessed whether, and to what extent, capuchin monkeys\u27 ability to solve a size discrimination problem is influenced by the type of procedure used to present the problem. Capuchins\u27 ability to generalise knowledge across different tasks was also evaluated. We trained eight adult tufted capuchin monkeys to select the larger of two stimuli of the same shape and different sizes by using pairs of food items (Experiment 1), computer images (Experiment 1) and objects (Experiment 2). Our results indicated that monkeys achieved the learning criterion faster with food stimuli compared to both images and objects. They also required consistently fewer trials with objects than with images. Moreover, female capuchins had higher levels of acquisition accuracy with food stimuli than with images. Finally, capuchins did not immediately transfer the solution of the problem acquired in one task condition to the other conditions. Overall, these findings suggest that - even in relatively simple visual discrimination problems where a single perceptual dimension (i.e., size) has to be judged - learning speed strongly depends on the mode of presentation

Temporal variability and effect of environmental variables on airborne bacterial communities in an urban area of Northern Italy

Despite airborne microorganisms representing a relevant fraction of atmospheric suspended particles, only a small amount of information is currently available on their abundance and diversity and very few studies have investigated the environmental factors influencing the structure of airborne bacterial communities. In this work, we used quantitative PCR and Illumina technology to provide a thorough description of airborne bacterial communities in the urban area of Milan (Italy). Forty samples were collected in 10-day sampling sessions, with one sessionper season.Themeanbacterialabundancewasabout104 ribosomal operons perm3 of air andwas lower inwinter than in the other seasons. Communitieswere dominated by Actinobacteridae, Clostridiales, Sphingobacteriales and fewproteobacterial orders (Burkholderiales, Rhizobiales, Sphingomonadales andPseudomonadales).Chloroplastswere abundant in all samples. Ahigher abundanceof Actinobacteridae,which are typical soil-inhabiting bacteria, and a lower abundance of chloroplasts in samples collected on cold days were observed. The variation in community composition observed within seasons was comparable to that observed between seasons, thus suggesting that airborne bacterial communities showlarge temporal variability, even between consecutive days. The structure of airborne bacterial communities therefore suggests that soil and plants are the sources which contribute most to the airborne communities of Milan atmosphere, but the structure of the bacterial community seems to depend mainly on the source of bacteria that predominates in a given period of time

Distribution Pattern of Urban Street Trees in Rome (Italy): A Multifactorial Evaluation of Selection Criteria

Street trees play a significant ecological role in modern urban ecosystems, but usually the selection criteria follow pragmatic reasons rather than bio-ecological suitability. Understanding the influence of such factors can be relevant, especially in cities having a certain complexity and area. This paper aims to analyze the variation in the distribution of street tree species within the city’s municipia of Rome to determine the influence of some factors in the selection process. Here, we have described the species of street trees in fourteen municipia of Rome, and we created five clusters of factors (bio-ecological, aesthetic, historical–cultural, health, and economic) that could constitute selection criteria for street trees. From our data analysis, the municipia of Rome were grouped into four main groups and the choice of trees was based on multiple selection criteria. Foliage type, longevity, fruit type, autochthony, and economic value were the primary criteria. In 90–100% of municipia, deciduous species dominate, with 50–150 years longevity, dry fruits, exotic species, and prices of <€500 per tree. Additionally, the flower type, allergenicity, size class, and cultural value were the secondary criteria. The biological and ecological characteristics of trees are key factors to consider in order to reduce the management of street trees and relative costs

On the red photoluminescence emission from surface-oxidised silicon nanocrystals

The process responsible for the visible-near infrared photoluminescence (PL) emission in Si nanostructures has been generating significant controversy for years. Models based on band to band recombination of electrons and holes in Si nanostructures, or on recombination at defects located at the surface are currently proposed, but it is experimentally difficult to distinguish the two mechanisms since both are size-dependent. Here we compare the spectroscopic properties of Si nanocrystals (Si-nc), as prepared by laser pyrolysis and after complete conversion to amorphous silica by alkali etching-assisted oxidation. The strong resemblance of the spectral and time-behavior of the red PL emission in both systems, suggests that this emission is dominated by oxide-related defect states. We show that the non-exponential time decay of the PL emission in both systems (Si-nc and oxidised amorphous sample), can be modelled as the sum of exponential decays from four emitting centres thus ruling out the interpretation in terms of the so-called "stretched exponential" function. By analysing their emission properties, we show the four emitting centres are actually non-bridging oxygen defects. Changes in the emission energies of these defects, due to size-dependent strain and chemical inhomogeneity, can be erroneously attributed to quantum confinement effect in the Si-nc
