The Acute-Phase Proteins Serum Amyloid A and C Reactive Protein in Transudates and Exudates

The distinction between exudates and transudates is very important in the patient management. Here we evaluate whether the acute-phase protein serum amyloid A (SAA), in comparison with C reactive protein (CRP) and total protein (TP), can be useful in this discrimination. CRP, SAA, and TP were determined in 36 exudate samples (27 pleural and 9 ascitic) and in 12 transudates (9 pleural and 3 ascitic). CRP, SAA, and TP were measured. SAA present in the exudate corresponded to 10% of the amount found in serum, that is, the exudate/serum ratio (E/S) was 0.10 ± 0.13. For comparison, the exudate/serum ratio for CRP and TP was 0.39 ± 0.37 and 0.68 ± 0.15, respectively. There was a strong positive correlation between serum and exudate SAA concentration (r = 0.764;p < 0.0001). The concentration of SAA in transudates was low and did not overlap with that found in exudates (0.02-0.21 versus 0.8–360.5 g/mL). SAA in pleural and ascitic exudates results mainly from leakage of the serum protein via the inflamed membrane. A comparison of the E/S ratio of SAA and CRP points SAA as a very good marker in discriminating between exudates and transudates

The effect of elastic abdominal binder use on respiratory function on persons with high spinal cord injury at orthostatic position

Introduction : Spinal cord injury causes respiratory muscles paralysis, especially in high thoracic paraplegia and tetraplegia with injury above or right on the sixth thoracic segment, and also biomechanics, volumes, capacities and respiratory pressures changes in affected people. The elastic abdominal binder provides a mechanical support for respiratory function treatment, assisting with abdominal restraint and abdominal compliance reduction while at orthostatic position. Objective : To verify the elastic abdominal binder effect on the respiratory function of people with spinal cord injuries during standing position with the help of orthostatic table, from vertical angle position of 60° and 90°. Method : The study included 56 people suffering from spinal cord injury with motor level above or right on the sixth thoracic segment. They were randomly divided into four distinct groups regarding the use or not of the binder and different inclinations of the orthostatic table during the evaluation procedure. The measured outcomes were vital capacity, tidal volume, inspiratory and expiratory pressure and oxygen saturation. The descriptive analysis presented according to average and standard deviation or median and interquartile. For the outcomes analysis of the five evaluations, the Analysis of Variance (ANOVA) of two factors with repeated measures was used. Statistical significance was set at 5%. Results : The values obtained from respiratory parameters showed no statistical significance regarding the elastic abdominal binder intervention nor on the angle of the standing position. Conclusion : There was no contrasting effect regarding the use of the binder among the evaluated people, therefore it should not be nominated as a standard procedure in the treatment of spinal cord injury at orthostatic position. However, this procedure should not be absolute contraindicated, thus its effect has not demonstrated any harm to participants. Introdução : A lesão da medula espinhal ocasiona paralisia dos músculos respiratórios, principalmente na tetraplegia e paraplegia torácica alta, com lesão acima ou igual ao sextosegmento torácico, e assim mudanças na biomecânica, volumes, capacidades e pressões respiratórias das pessoas acometidas. A cinta abdominal elástica proporciona um suporte mecânico ao tratamento e cuidados com as alterações da função respiratória destas pessoas, podendo auxiliar na contenção abdominal, reduzindo a complacência abdominal durante a posição ortostática. Objetivo : Verificar os efeitos que a cinta abdominal elástica proporciona à função respiratória das pessoas com lesão medular posicionadas em ortostatismo com auxílio da mesa ortostática, a partir da posição a 60° e 90° de angulação vertical. Método : Participaram deste estudo 56 pessoas acometidas por lesão medular com nível motor igual ou acima do sexto segmento torácico, divididos aleatoriamente em quatro grupos distintos em relação ao uso ou não da cinta e angulações da mesa ortostática durante o procedimento de avaliação. Os desfechos mensurados foram capacidade vital, volume corrente, pressão inspiratória e expiratória máxima e saturação de oxigênio. A análise descritiva apresentou-se por meio de média e desvio padrão ou mediana e interquartis. Para análise dos desfechos nos cinco momentos avaliados utilizou-se a Análise de Variância (ANOVA) de dois fatores com medidas repetidas. A significância estatística foi estipulada em 5%. Resultados : Os valores encontrados para os parâmetros respiratórios avaliados demonstraram que não houve significância estatística em relação à intervenção cinta abdominal elástica e à angulação do ortostatismo. Conclusão : Não houve efeito diferencial em relação ao uso da cinta nas pessoas avaliadas, não podendo ser indicada como um procedimento padrão para as abordagens de tratamento na posição ortostática na lesão medular espinhal. Em contrapartida, este procedimento não deve ser uma contraindicação absoluta, pois, seu efeito não demonstrou malefícios aos participantes

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states
