Jornal de Pneumologia , 2000,
Abstract: Asma é doen a com alta prevalência em nosso meio e ao redor do mundo. Embora novas op es terapêuticas tenham sido recentemente desenvolvidas, parece haver aumento mundial na sua morbidade e mortalidade. Em muitas institui es, as exacerba es asmáticas ainda constituem emergência médica muito comum. As evidências têm demonstrado que a primeira hora no manejo da asma aguda na sala de emergência concentra decis es cruciais que podem determinar o desfecho desta situa o clínica. Nesta revis o n o-sistemática, os autores enfocaram a primeira hora da avalia o e tratamento do paciente com asma aguda na sala de emergência, descrevendo uma estratégia apropriada para o seu manejo. S o consideradas as seguintes etapas: diagnóstico, avalia o da gravidade, tratamento farmacológico, avalia o das complica es e decis o sobre onde se realizará o tratamento adicional. Espera-se que estas recomenda es contribuam para que o médico clínico tome a decis o apropriada na primeira hora do manejo da asma aguda.

Abstract: asthma is a disease with high prevalence in our country and around the world. although new therapeutic approaches have been recently developed, there appears to be a worldwide increase in morbidity and mortality from asthma. in many institutions, asthma exacerbation is still a common medical emergency. clinical evidence demonstrates that the first hour of management of acute asthma in the emergency room entails crucial decisions that could be determinant in the clinical outcome. in this non-systematic review, the authors focus on the first hour assessment and treatment of patients with acute asthma and outline an appropriate strategy for their management. diagnosis, severity assessment, pharmacological treatment, complications, and the decision regarding the place where additional treatment will take place will be considered. it is reasonable to expect that these recommendations will help physicians make appropriate decisions about the first hour care of acute asthma in the emergency room.
Bronze Furniture from the domus of Piazza Marconi in Cremona Arredi di bronzo dalla domus di piazza Marconi a Cremona

Abstract: La domus di piazza Marconi fu costruita in età augustea al limite sud della città romana. Nel I secolo, la domus è stata la dimora di una famiglia di notevoli possibilità economiche, sicuramente importante all’interno della compagine sociale e politica dell’antica Cremona; lo rivelano l’alta qualità degli affreschi, dei pavimenti, dei mosaici, e degli arredi in pietra che ornavano i cortili e le stanze di rappresentanza. Anche se è probabile che la maggior parte degli oggetti di bronzo sia stata trafugata dai soldati di Vespasiano durante il saccheggio del 69 d.C., i reperti rimasti, tra recipienti e arredi, offrono un interessante quadro della suppellettile in metallo di una ricca dimora cisalpina, con un termine ante quem che richiama immediatamente il più noto modello delle città vesuviane. The domus of Piazza Marconi was built in the Augustan age in the southern end of the Roman city. In the I century, the domus was the home of a family of great economic possibilities, certainly important within the social and politic structure of the old Cremona; it is revealed by the high quality of the frescoes, the floors, the mosaics, and the stone furnishings that adorned the courtyards and reception rooms. Although it is likely that the majority of bronze objects have been stolen by soldiers during the sack of Vespasian in 69 AD, the remaining findings, including containers and furniture, offer an interesting picture of the metal furnishings in a rich home of the Cisalpine, with a terminus ante quem that immediately recalls the more famous model of the Vesuvian cities.

Percebeu-se que os pais que estabelecem uma boa rela o de apego com seus filhos portadores de DA, revelaram maior colabora o com as rotinas de cuidado das crian as, apresentando uma evolu o clínica mais rápida, com diminui o das les es de pele.
Calculating the Soil Surface Nitrogen Balance at Regional Scale: Example Application and Critical Evaluation of Tools and Data
Luca Bechini,Nicola Castoldi
Italian Journal of Agronomy , 2011, DOI: 10.4081/ija.2006.665
Abstract: Agro-ecological indicators (AEIs) allow evaluating sustainability for a large number of farms. The SITPAS Information System developed for the agricultural park “Parco Agricolo Sud Milano” (northern Italy) contains detailed farming and cropping systems information for 731 farms that can be used for these analyses. We used the SITPAS database to evaluate N management with an AEI and to evaluate the suitability of the SITPAS data model for this type of applications. The AEI (soil surface N balance) was calculated for each crop at field scale, as the difference between the sum of N inputs (atmospheric depositions, biological fixation, fertilisers, residues from previous crop) and crop N uptake; the results were aggregated at rotation and farm levels. The farming systems with the highest surplus (> 300 kg N ha-1) are dairy, cattle and pig farms, in which chemical N fertilisers are used in addition to animal manures. The crops with the highest surplus are Italian ryegrass and maize (183 and 172 kg N ha-1, respectively), while rice and wheat have the lowest surplus (87 and 85 kg N ha-1). The data model allowed to store and analyse complex information not manageable otherwise; its main limitation was the excessive flexibility, requiring a complicated procedure for the calculations of this example, and the exclusion of most data at the farming systems level (corresponding to 82% of the studied area) for missing, incomplete, out-of-range or inconsistent data. These results suggest to promote actions towards better N management in cropping systems in the Park and to develop simple data models based on minimum data requirements when sustainability evaluations are to be conducted.
Methodological Aspects of On-Farm Monitoring of Cropping Systems Management

Italian Journal of Agronomy , 2007, DOI: 10.4081/ija.2008.287
Abstract: To conduct agro-environmental assessments at field and farm scale, detailed management data of crop and animal production systems are needed. However, this type of data is only rarely collected by public administrations. In the period 2005-2006, we made an experience of on-farm monitoring of cropping systems management, within a larger project aimed at assessing sustainability of agricultural systems in Italian Parks. In this paper, we describe and discuss the steps taken to carry out periodic face-to-face interviews in farms in the Sud Milano Agricultural Park (northern Italy). The first step was the selection of seven farms, which we identified by applying cluster analysis at a large database describing 733 farms of the Park. After having identified the most relevant agro-environmental issues in the studied area, we established a list of simple but sound indicators to evaluate the effects of agricultural management on the environment. The criteria used to select the indicators were that they should: be calculated on easily available data, not be based on direct measurements, make a synthesis of different aspects of reality, and be easily calculated and understood. The indicators selected evaluate nutrient management, fossil energy use, pesticide toxicity, soil management, and economic performance. Subsequently, we designed a data model to store input data used to calculate the indicators (farm configuration, flows of materials and money through the farm gate, animals and their rations, history of crop cultivation, crop management). The data model that we obtained is relatively complex, but adequate to store and analyse the large amount of data acquired during the two-year project. A questionnaire was developed to fully comply with the indicators selected and the data model. The questionnaire was used to carry out approximately six interviews per farm each year, with an investment of time of 1-2 hours per interview. Appropriate double checks of data collected in the interviews were put in place to ensure a good data quality. The data collected were used for the calculation of several agro-ecological indicators. The results show that nutrient management in maize is not satisfactory due to high surpluses, while meadows have the lowest surplus. The fertilisers and diesel consumption are the most important energy inputs to maize, while their importance is lower for the other crops. Seeds and fertilisers are the main costs for maize and winter cereals, while diesel consumption represents a large part of the economic costs for meadows; pesticides are the pri
Energy, Nutrient and Economic Cross Indicators of Cropping Systems in Northern Italy
Nicola Castoldi,Luca Bechini
Italian Journal of Agronomy , 2010, DOI: 10.4081/ija.2010.19
Abstract: Agro-ecological indicators are useful tools to provide synthetic representations of agricultural systems. Simple indicators can be combined to calculate cross indicators, for example efficiencies, calculated as a ratio between two simple indicators. In sustainability studies, efficiency is frequently calculated in energy terms (energy output / energy input); however, other “output” and “input” terms can be used. In this study, we evaluated how the ranking of systems changes when different metrics of agricultural production (economic gross margin vs. energy output) and resource use (nutrients inputs and surpluses, fossil energy inputs, economic costs) are used. The calculations were carried out for a study area in northern Italy (Sud Milano Agricultural Park), characterised by intensively cultivated arable cropping systems (cereals and forage crops). Crop types were ranked differently when metrics changed. In general, maize (a highly productive crop) had good performances when evaluated using the output / input energy ratio, while rice was good when we used the ratios based on gross margin. When energy or monetary outputs were divided by N surplus, all crop types had very similar median values, suggesting a common energetic and economic efficiency of N use. Overall, different cross indicators may provide a different representation of the system studied. This means that it is not possible to provide a unique synthetic evaluation of sustainability, which instead depends on the indicator(s) chosen.We conclude that it is very important to clarify the objective of sustainability studies and to select accordingly the most adequate indicators.
