The Acute STroke Registry and Analysis of Lausanne (ASTRAL): design and baseline analysis of an ischemic stroke registry including acute multimodal imaging.

BACKGROUND AND PURPOSE: Stroke registries are valuable tools for obtaining information about stroke epidemiology and management. The Acute STroke Registry and Analysis of Lausanne (ASTRAL) prospectively collects epidemiological, clinical, laboratory and multimodal brain imaging data of acute ischemic stroke patients in the Centre Hospitalier Universitaire Vaudois (CHUV). Here, we provide design and methods used to create ASTRAL and present baseline data of our patients (2003 to 2008). METHODS: All consecutive patients admitted to CHUV between January 1, 2003 and December 31, 2008 with acute ischemic stroke within 24 hours of symptom onset were included in ASTRAL. Patients arriving beyond 24 hours, with transient ischemic attack, intracerebral hemorrhage, subarachnoidal hemorrhage, or cerebral sinus venous thrombosis, were excluded. Recurrent ischemic strokes were registered as new events. RESULTS: Between 2003 and 2008, 1633 patients and 1742 events were registered in ASTRAL. There was a preponderance of males, even in the elderly. Cardioembolic stroke was the most frequent type of stroke. Most strokes were of minor severity (National Institute of Health Stroke Scale [NIHSS] score ≤ 4 in 40.8% of patients). Cardioembolic stroke and dissections presented with the most severe clinical picture. There was a significant number of patients with unknown onset stroke, including wake-up stroke (n=568, 33.1%). Median time from last-well time to hospital arrival was 142 minutes for known onset and 759 minutes for unknown-onset stroke. The rate of intravenous or intraarterial thrombolysis between 2003 and 2008 increased from 10.8% to 20.8% in patients admitted within 24 hours of last-well time. Acute brain imaging was performed in 1695 patients (97.3%) within 24 hours. In 1358 patients (78%) who underwent acute computed tomography angiography, 717 patients (52.8%) had significant abnormalities. Of the 1068 supratentorial stroke patients who underwent acute perfusion computed tomography (61.3%), focal hypoperfusion was demonstrated in 786 patients (73.6%). CONCLUSIONS: This hospital-based prospective registry of consecutive acute ischemic strokes incorporates demographic, clinical, metabolic, acute perfusion, and arterial imaging. It is characterized by a high proportion of minor and unknown-onset strokes, short onset-to-admission time for known-onset patients, rapidly increasing thrombolysis rates, and significant vascular and perfusion imaging abnormalities in the majority of patients.

Demonstração dos fluxos de caixa como instrumento de planeamento financeiro e de tomada de decisão

O presente trabalho tem como objectivo evidenciar a importancia da demonstração dos fluxos de caixa como instrumento de planeamento financeiro e de tomada de decisão. As informações fornecida pela demonstração dos fluxos de caixa serão de grande utilidade para a Administração, pois permitem compreender a alocação dos meios financeiros da entidade o que ajudará no planeamento financeiro e na tomada de decisões económico-financeiras. A demonstração dos fluxos de caixa como peça contabilística permite a Administração verificar a consistência dos planos projectados e estimar as exigências financeiras da entidade. O trabalho inclui uma abordagem teórica seguido de um estudo de caso. Na abordagem teórica, fez-se a apresentação das principais teorias e conceitos sobre o tema. O estudo de caso incidiu sobre uma empresa nacional, a Enacol, em que analisou-se a demonstração do fluxo de caixa dos ultimos três anos, bem como os indicadores económicos e financeiros possibilitando a análise da situação financeira da empresa. Foi também utilizada a entrevista a pessoas ligadas a área de contabilidade numa empresa. Os resultados obtidos mostram que a demonstração dos fluxos de caixa é um importante instrumento no planeamento financeiro e na tomada de decisões para a continuidade dos negócios das empresas. This paper aims to highlight the importance of the statement of cash flows as a tool for financial planning and decision making. All the information provided by the statement of cash flows will be very useful for the Administration, because they allow them to understand the allocation of the financial resources of the entity which will be a support in financial planning and decisionmaking in economic and financial areas. Being part of accounting, the statement of cash flows allows the Administration to verify the consistency of the projected plans and estimate the organization financial requirements. The following work includes a theoretical approach followed by a case study. Within the theoretical approach was made a presentation of the main theories and concepts on the subject while the case study focused on a national company, Enacol, in which we analyzed the statement of cash flows for the last three years, as well as the economic and financial indicators enabling the analysis of the financial situation of the company. It was also used an interview used for people connected to a company in the accounting field. Therefore, the results show that the statement of cash flows is an important tool in financial planning and decision making for the continuity of companies businesses.

The changing relationship between tax and financial reporting in Spain

The degree of connection between tax and financial reporting is regarded as a key factor in the study of international accounting differences. The position for Spain is briefly outlined in previous research but without examination of any specific accounting issues except, in outline only, depreciation and the tax-free revaluation of assets from 1977 to 1983. The absence of a detailed study of the major tax/accounting linkages for Spain is of particular importance because the relationship is regarded as having changed dramatically in the early 1990s, from a position of tax dominance. In order to measure the links between tax and financial reporting, we adopt the methodology of Lamb et al. (1998) by assessing major accounting topics using a five-case classification shown as Table 1. We refute the proposition that suggests that the link between tax/accounting has been reduced substantially.

Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe of detritivores

Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe of detritivores. The purpose of this paper is to establish a phylogenetic basis for a new Eumaeini subtribe that includes those lycaenid genera in which detritivory has been recorded. Morphological characters were coded for 82 species of the previously proposed "Lamprospilus Section" of the Eumaeini (19 of these had coding identical to another species), and a phylogenetic analysis was performed using the 63 distinct ingroup terminal taxa and six outgroups belonging to four genera. Taxonomic results include the description in the Eumaeini of Calycopidina Duarte & Robbins new subtribe (type genus Calycopis Scudder, 1876), which contains Lamprospilus Geyer, Badecla Duarte & Robbins new genus (type species Thecla badaca Hewitson), Arzecla Duarte & Robbins new genus (type species Thecla arza Hewitson), Arumecla Robbins & Duarte, Camissecla Robbins & Duarte, Electrostrymon Clench, Rubroserrata K. Johnson & Kroenlein revalidated status, Ziegleria K. Johnson, Kisutam K. Johnson & Kroenlein revalidated status, and Calycopis. Previous "infratribe" names Angulopina K. Johnson & Kroenlein, 1993, and Calycopina K. Johnson & Kroenlein, 1993, are nomenclaturally unavailable and polyphyletic as proposed. New combinations include Badecla badaca (Hewitson), Badecla picentia (Hewitson), Badecla quadramacula (Austin & K. Johnson), Badecla lanckena (Schaus), Badecla argentinensis (K. Johnson & Kroenlein), Badecla clarissa (Draudt), Arzecla arza (Hewitson), Arzecla tarpa (Godman & Salvin), Arzecla canacha (Hewitson), Arzecla calatia (Hewitson), Arzecla tucumanensis (K. Johnson & Kroenlein), Arzecla sethon (Godman & Salvin), Arzecla nubilum (H. H. Druce), Arzecla paralus (Godman & Salvin), Arzecla taminella (Schaus), Arzecla albolineata (Lathy), Electrostrymon denarius (Butler & H.Druce), Electrostrymon guzanta (Schaus), Electrostrymon perisus (H. H. Druce), Rubroserrata mathewi (Hewitson), Rubroserrata ecbatana (Hewitson), Kisutam micandriana (K. Johnson), and Kisutam syllis (Godman & Salvin). The structure of the male genitalia lateral window, labides, and brush organs are described and discussed, as are the female genitalia signa of the corpus bursae and 8th abdominal tergum. Widespread wing pattern sexual dimorphism in the Calycopidina is noted and illustrated, and the presence of alternating dark and light bands on the ventral wings of both sexes is discussed. The evidence for detritivory in Lamprospilus, Badecla, Arzecla, Arumecla, Camissecla, Electrostrymon, Ziegleria, Kisutam, and Calycopis is summarized using the new classification.

Economic and Workforce Development Task Force Report, August 2008

The 2008 disasters devastated businesses, farms, homes, schools, non-profit institutions, entire communities, and people’s lives across the state of Iowa. The Rebuild Iowa Advisory Commission (RIAC) is charged by the Governor to guide the state’s recovery and reconstruction process. The Economic and Workforce Development Task Force is respectfully submitting this report to be included and considered in the deliberations of the RIAC. While economic and workforce development are two issues that are inextricably linked and critical to Iowa’s rebuilding strategies, each also requires extraordinary attention in determining what needs to be considered in the very immediate and longer-term recovery.

Neglected risks, financial innovation and financial fragility

We present a standard model of financial innovation, in which intermediaries engineer securities with cash flows that investors seek, but modify two assumptions. First, investors (and possibly intermediaries) neglect certain unlikely risks. Second, investors demand securities with safe cash flows. Financial intermediaries cater to these preferences and beliefs by engineering securities perceived to be safe but exposed to neglected risks. Because the risks are neglected, security issuance is excessive. As investors eventually recognize these risks, they fly back to safety of traditional securities and markets become fragile, even without leverage, precisely because the volume of new claims is excessive.

Toxicological and ultrastructural analysis of the impact of pesticides used in temperate fruit crops on two populations of Chrysoperla externa (Neuroptera, Chrysopidae)

This study aimed to evaluate the effects of (g a.i. L-1) abamectin (0.02), carbaryl (1.73), sulphur (4.8), fenitrothion (0.75), methidathion (0.4), and trichlorfon (1.5) on the survival of larvae and pupae, on the oviposition of adults and hatching of eggs from treated Chrysoperla externa third-instar larvae from two different populations (Bento Gonçalves and Vacaria, Rio Grande do Sul State, Brazil). Morphological changes caused by abamectin to eggs laid by C. externa from Vacaria population were evaluated by mean of ultrastructural analysis. The pesticides were applied on glass plates. Distilled water was used as control. For the evaluation of larvae mortality, a fully randomized experimental design in a 2 x 7 (two populations x seven treatments) factorial scheme was used, whereas for the effects of the compounds on oviposition capacity and egg viability, a 2 x 4 factorial scheme was used. Carbaryl, fenitrothion, and methidathion caused 100% mortality of larvae. Abamectin reduced the hatching of eggs from treated third-instar larvae of both populations; however, this pesticide presented highest toxicity on insects from Vacaria. The ultrastructural analysis showed that abamectin caused malformations in micropyle and in chorion external surface of C. externa eggs. Based in the total effect (E), carbaryl, fenitrothion, and methidathion are harmful to C. externa; trichlorfon is harmless to third-instar larvae, while abamectin and sulphur are harmless and slightly harmful to third-instar larvae from Bento Gonçalves and Vacaria, respectively.

Human nature and institutional analysis

This essay reviews some findings in cognition sciences and examines their consequences for the analysis of institutions. It starts by exploring how humans specialization in producing knowledge ensures our success in dominating the environment but also changes fast our environment. So fast that it did not give time to natural selection to adapt our biology, causing it to be potentially maladapted in important dimensions. A main function of institutions is therefore to fill the gap between the demands of our relatively new environment and our biology, still adapted to our ancestral environment as hunter-gatherers. Moreover, institutions are built with the available elements, which include our instincts. A deeper understanding of both aspects, their adaptive function and this recruitment of ancestral instincts, will add greatly to our ability to manage institutions.

Clinicopathologic and molecular analysis of a choroidal pigmented schwannoma in the context of a PTEN hamartoma tumor syndrome.

PURPOSE: To report the first case of choroidal schwannoma in a patient affected by PTEN hamartoma tumor syndrome (PHTS) and investigate the molecular involvement of the phosphatase and tensin homolog (PTEN) and neurofibromin 2 (NF2) genes in this rare intraocular tumor. DESIGN: Observational case report. PARTICIPANT: A 10-year-old girl diagnosed with PHTS. METHODS: The enucleated specimen underwent histologic, immunohistochemical, and transmission electronic microscopy. The expression of PTEN and NF2 and their protein products were evaluated by reverse transcription-polymerase chain reaction and immunohistochemistry. Somatic mutations of PTEN and NF2, as well as allelic loss, were investigated by direct sequencing of DNA extracted from the tumor. PTEN epigenetic silencing was investigated by pyrosequencing. MAIN OUTCOME MEASURES: Histopathologic and molecular characterization of a choroidal pigmented schwannoma. RESULTS: Histopathologic, immunohistochemical, and electron microscopic analysis demonstrated features consistent with a pigmented cellular schwannoma of the choroid. We found no loss of heterozygosity at the genomic level for the PTEN germline mutation and no promoter hypermethylation or other somatic intragenic mutations. However, we observed an approximate 40% reduction of PTEN expression at both the mRNA and the protein level, indicating that the tumor was nonetheless functionally deficient for PTEN. Although DNA sequencing of NF2 failed to identify any pathologic variants, its expression was abolished within the tumor. CONCLUSIONS: We report the first description of a pigmented choroidal schwannoma in the context of a PHTS. This rare tumor showed a unique combination of reduction of PTEN and absence of NF2 expression.

Análisis de viabilidad técnica-económica del parque eólico Altos de Peralta

RESUMEN La energia eolica se considera una forma indirecta de energia solar. Entre el 1 y 2% de la energia proveniente del sol se convierte en viento, debido al movimiento del aire ocasionado por el desigual calentamiento de la superficie terrestre. La energia cinetica del viento puede transformarse en energia util, tanto mecanica como electrica. La energia eolica, transformada en energia mecanica ha sido historicamente aprovechada, pero su uso para la generacion de energia electrica es mas reciente, en respuesta a la crisis del petroleo y a los impactos ambientales derivados del uso de combustibles. El objetivo principal de este trabajo es hacer un analisis de viabilidad desde un punto de vista tecnico y economico de un parque eolico situado en el municipio de Barasoain (Navarra). Desde el punto de vista tecnico se han estudiado los aspectos constructivos del parque considerando sus diferentes infraestructuras de obra civil y electrica asi como los niveles de recurso eolico. En el ambito economico y financiero se han analizado los aspectos y ratios mas relevantes que definen un proyecto de estas caracteristicas asi como el modelo de financiacion elegida basada en el Project- Finance. Entre las conclusiones mas destacadas de este proyecto cabe destacar la contribucion de la construccion del parque al desarrollo social y economico de la zona donde queda ubicado contribuyendo a la creacion de puestos de trabajo, tanto en la fase de construccion como de explotacion y una perfecta armonia con condicionantes medioambientales de la zona. El analisis tecnico realizado nos indica la viabilidad tecnica del parque tanto desde el punto de vista de recurso eolico como la idoneidad para poder evacuar la energia producida. Por otro lado, los resultados obtenidos cumplen perfectamente con los estandares requeridos por los financiadores de los parques y resultando ser muy atractivos para sus accionistas
