Acute Treatment of Isolated Posterior Cerebral Artery Occlusion: Single Center Experience

Background and objectives: Randomized trials for mechanical thrombectomy (MT) excluded patients with ischemic strokes due to isolated posterior cerebral artery occlusion (IPCAO), and there is no evidence for best acute treatment strategy in these patients. We aimed to assess the effectiveness and safety of MT in acute IPCAO. Methods: We retrospectively analyzed consecutive patients with acute stroke due to IPCAO submitted to MT and/or intravenous thrombolysis (IVT), between 2015-2019. Effectiveness outcomes (recanalization rate, first-pass effect, NIHSS 24h improvement and 3-month Modified Ranking Scale - mRS) and safety outcomes (complications, symptomatic intracranial hemorrhage (SICH) and 3-month mortality) were described and compared between groups. Results: A total of 38 patients were included, 25 underwent MT and 13 had IVT alone. Successful and complete recanalization were achieved in 68% and 52% of MT patients, respectively. NIHSS improvement at 24h was found in 56% of MT patients versus 30.8% of patients submitted to IVT alone (OR [95% CI]=2.86 [0.69-11.82]) and excellent functional outcome at 3 months (mRS≤1) was achieved in 54.2% of MT patients versus 38.5% in the IVT group (OR [95% CI]=1.60 [0.41-6.32]). Complications occurred in 3 (12%) procedures and there were no SICH. Mortality at 3 months was 20% in the MT group and 15.4% in patients submitted to IVT alone. Conclusions: Our results reflect a real-world scenario in a single center and seem to support the recently growing literature showing that MT is a feasible and safe treatment in IPCAO, with favorable effectiveness.info:eu-repo/semantics/publishedVersio

Morphologic and Genetic Analysis of Synhimantus (Synhimantus) laticeps from a Long-Eared Owl (Asio otus)

The long-eared owl (Asio otus) is a medium-sized owl species that is well-distributed in almost all of the territories in Portugal. Nematodes were found in the oral cavity of a long-eared owl (A. otus) admitted to CRASSA (Wildlife Rehabilitation Centre of Santo Andre). During a physical exam and stabilization of the bird, five nematodes were collected. The worms were examined and measured under light microscopy, and photos were taken. After a morphological analysis was conducted, all the nematodes (five females) were identified as Synhimantus (Synhimantus) laticeps. Two specimens were subjected to molecular analysis, which confirmed the result. This study provides a combined morphological and genetic approach to S. laticeps. To the authors' best knowledge, this is the first report including genetic sequencing of S. laticeps in a long-eared owl (A. otus) from Portugal.This work was supported by the projects UIDB/CVT/00772/2020 and LA/P/0059/2020 funded by the Portuguese Foundation for Science and Technology (FCT).

Acute hemorrhagic oedema of infancy

O edema hemorrágico agudo infantil é uma forma rara de vasculite leucocitoclásica cutânea, que ocorre em crianças com menos de 4 anos de idade. As principais manifestações são lesões cutâneas purpúricas, edema periférico e febre. Apesar dos achados clínicos serem dramáticos, quer na aparência das lesões, quer na rapidez de instalação, o prognóstico permanece excelente, com recuperação espontânea em poucas semanas. A sua origem está pouco esclarecida, mas infecções subjacentes, fármacos e vacinas têm sido referidas como possíveis factores etiológicos. Descrevemos uma criança de 7 meses com quadro clínico e histológico típicos de edema hemorrágico agudo infantil que surgiu na sequência de uma infecção do tracto urinário, em tratamento com amoxicilina e ácido clavulâmico.info:eu-repo/semantics/publishedVersio

The Dynamics of Nestedness Predicts the Evolution of Industrial Ecosystems

In economic systems, the mix of products that countries make or export has been shown to be a strong leading indicator of economic growth. Hence, methods to characterize and predict the structure of the network connecting countries to the products that they export are relevant for understanding the dynamics of economic development. Here we study the presence and absence of industries at the global and national levels and show that these networks are significantly nested. This means that the less filled rows and columns of these networks' adjacency matrices tend to be subsets of the fuller rows and columns. Moreover, we show that nestedness remains relatively stable as the matrices become more filled over time and that this occurs because of a bias for industries that deviate from the networks' nestedness to disappear, and a bias for the missing industries that reduce nestedness to appear. This makes the appearance and disappearance of individual industries in each location predictable. We interpret the high level of nestedness observed in these networks in the context of the neutral model of development introduced by Hidalgo and Hausmann (2009). We show that, for the observed fills, the model can reproduce the high level of nestedness observed in these networks only when we assume a high level of heterogeneity in the distribution of capabilities available in countries and required by products. In the context of the neutral model, this implies that the high level of nestedness observed in these economic networks emerges as a combination of both, the complementarity of inputs and heterogeneity in the number of capabilities available in countries and required by products. The stability of nestedness in industrial ecosystems, and the predictability implied by it, demonstrates the importance of the study of network properties in the evolution of economic networks.Comment: 26 page

Determinants of the income velocity of money in Portugal: 1891–1998

This paper performs a long-run time series analysis of the behaviour of the income velocity of money in Portugal between 1891 and 1998 by assessing the importance of both macroeconomic and institutional factors and looking for particularities in the Portuguese case. We estimate two cointegration vectors for the income velocity of money, macroeconomic variables and institutional variables. It is apparent that one of these vectors reflects the relationship between income velocity and macroeconomic variables, while the other reflects the relationship between income velocity and institutional variables. Moreover, a regression analysis reveals that the usual U-shaped pattern is displayed with a relatively late inflection point located around 1970, which is consistent with the Spanish case. It is further noted that this is a feature of countries with a late economic and institutional development process.info:eu-repo/semantics/publishedVersio

The major barriers to evidence-informed conservation policy and possible solutions

Conservation policy decisions can suffer from a lack of evidence, hindering effective decision-making. In nature conservation, studies investigating why policy is often not evidence-informed have tended to focus on Western democracies, with relatively small samples. To understand global variation and challenges better, we established a global survey aimed at identifying top barriers and solutions to the use of conservation science in policy. This obtained the views of 758 people in policy, practice, and research positions from 68 countries across six languages. Here we show that, contrary to popular belief, there is agreement between groups about how to incorporate conservation science into policy, and there is thus room for optimism. Barriers related to the low priority of conservation were considered to be important, while mainstreaming conservation was proposed as a key solution. Therefore, priorities should focus on convincing the public of the importance of conservation as an issue, which will then influence policy-makers to adopt pro-environmental long-term policies.NERC (1653183) Grantham Foundation for the Protection of the Environment Kenneth Miller Trust (unknown) NERC (1653183) NERC (NE/L002507/1) European Commission (308454

Molecular detection and phylogenetic analysis of the gene H from canine distemper virus isolates circulating at the municipality of Campinas, São Paulo

Canine distemper virus (CDV), a Morbillivirus of the family Paramyxoviridae, is the etiological agent of neurological and systemic disease in dogs. The laboratory diagnosis of infection requires viral isolation or detection of genetic material of the virus in secretions or tissues of dogs with clinical suspicion of the disease. The genetic diversity among isolates of CDV can be assessed by sequencing and phylogenetic analysis of the gene that encodes the viral hemagglutinin (H gene), and there is currently a special interest in comparing the strains currently circulating in the field with the genogroup America-1, which comprises strains present in vaccines available in the market. In this study, the molecular detection of CDV gene H was performed from biological samples harvested ante-and post-mortem from 15 dogs with clinical signs suggestive of canine distemper in the metropolitan region of Campinas, São Paulo. Ten of the 15 dogs examined had at least one positive organ under molecular detection and the obtained amplicons were sequenced and further analyzed by molecular phylogenetic analysis. Similarly to what has already been reported on previous studies regarding the diversity of the gene H in other countries, the phylogenetic reconstruction obtained for the samples of cases of distemper from Campinas region showed they were grouped with the North American, European and Japanese newly described samples, a genetic group distinguished from classical samples of CDV, named America-1, which encompasses the vaccine strains Snyder Hill, Onderstepoort and Lederle.O vírus da cinomose canina (CDV), um Morbillivirus da família Paramyxoviridae, é o agente etiológico de doença neurológica e sistêmica em cães. O diagnóstico laboratorial da infecção requer o isolamento viral ou detecção do material genético do vírus em secreções ou tecidos de cães com suspeita clínica da doença. A diversidade genética entre os isolados de CDV pode ser aferida pelo sequenciamento efilogenia molecular do gene que codifica a hemaglutinina viral (gene H), havendo atualmente um especial interesse em comparar as amostras circulantes a campo com o genogrupo América-1, que abrange as cepas presentes nas vacinas disponíveis no mercado. No presente estudo, foi realizada a detecção molecular do gene H de CDV a partir de amostras biológicas colhidas ante- e post- -mortem de 15 cães com sinais clínicos sugestivos de cinomose na região metropolitana de Campinas, São Paulo. Dez dos 15 cães analisados tiveram ao menos um órgão positivo na detecção molecular e os amplicons obtidos foram submetidos ao sequenciamento nucleotídico seguido de análise filogenética molecular. De forma semelhante ao que já foi reportado para estudo analisando a diversidade do gene H em outros países, a reconstrução filogenética obtida para as amostras de casos de cinomose da região de Campinas demonstrou as mesmas foram agrupadas junto a amostras norte-americanas, europeias e japonesas recentes, em um grupo genético distinto do grupo de amostras clássicas de CDV, nomeado America-1, o qual engloba as estirpes vacinais Snyder Hill, Onderstepoort e Lederle.7277Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
