Anatomopatologia de bursite cervical (oncocercose) encontrada em bovinos abatidos sob inspeção estadual no estado do Rio de Janeiro

A patologia descritiva das lesões em animais domésticos de açougue permite enriquecer a literatura médica veterinária especializada em inspeção sanitária de carnes, assim como subsidiar tecnicamente os profissionais inspetores. A oncocercose é uma parasitose causada pelo nematódeo Onchocerca sp,, sendo que a espécie O. gutturosa é a que mais acomete bovinos na América do Sul. Foram avaliados, pelo exame anatomopatológico, dois casos de lesões localizadas no ligamento nucal de bovinos abatidos para o consumo. A macroscopia de um caso revelou bursite crônica, representada por grande quantidade de líquido citrino e viscoso e, ainda, muitos corpúsculos livres, elípticos e achatados desprovidos de raiz (arrizo). A microscopia dessas estruturas evidenciou moldes de fibrinas amorfos e eosinofílicos. O segundo caso foi caracterizado por bursite aguda, e a microscopia das lesões ligamentar e periligamentar revelou granulomas epitelioides com reação gigantocitária, centralizados por formações semelhantes ao Onchocerca sp

Estabilidade da polpa do bacuri (Platonia insignis Mart.) congelada por 12 meses Stability of the bacuri pulp (Platonia insignis Mart.) frozen for 12 months

Conduziu-se este trabalho, com o objetivo de realizar o processamento e avaliar a estabilidade da polpa de bacuri (Platonia insignis Mart.) submetida ao congelamento durante 12 meses. Durante o período de armazenamento não ocorreram alterações significativas nas características físico-químicas da polpa quanto aos teores de sólidos solúveis, pH, atividade de água, açúcares totais e redutores, vitamina C, compostos fenólicos poliméricos e oligoméricos, pectina total e solúvel e cor L, a* , b*, enquanto que a acidez total e relação SST/AT variaram com o tempo de armazenamento. Os compostos fenólicos dímeros apresentaram aumento em função do tempo. Pelos resultados obtidos, a polpa de bacuri não pode ser considerada uma boa fonte de vitamina C. Por outro lado, apresenta baixos teores de compostos fenólicos caracterizando a polpa como, potencialmente pouco adstringente e com potencial para o processamento. A qualidade microbiológica não foi alterada durante o período de armazenamento. Os resultados apontam a eficiência do congelamento na manutenção das características físico-químicas e microbiológicas da polpa de bacuri.<br>The objective of this work was to process and evaluate the stability of the bacuri (Platonia insignis Mart.) pulp submitted to freezing for 12 months. During the storage period there were significant changes in the physiochemical characteristics of the pulp as for the content of total soluble solids, pH, water activity, total and reducing sugars, vitamin C, polimer and oligomeric phenolic compounds , total and soluble pectin and color L, the a*, b *,while total acidity and soluble solids varied with the storange period. The dimers phenolic compounds incresead with the time. According to the results, the bacuri pulp cannot be considered a good source of vitamin C, but it presents low contents of phenolic compounds characterizing the pulp as little astringent, thus showing potential for the processing. The microbiological quality was not altered during the storage period indicating the efficiency of freezing for maintaining the physiochemical and microbiological characteristics of the bacuri pulp

Development and validation of a score to predict postoperative respiratory failure in a multicentre European cohort : A prospective, observational study

BACKGROUND Postoperative respiratory failure (PRF) is the most frequent respiratory complication following surgery. OBJECTIVE The objective of this study was to build a clinically useful predictive model for the development of PRF. DESIGN A prospective observational study of a multicentre cohort. SETTING Sixty-three hospitals across Europe. PATIENTS Patients undergoing any surgical procedure under general or regional anaesthesia during 7-day recruitment periods. MAIN OUTCOME MEASURES Development of PRF within 5 days of surgery. PRF was defined by a partial pressure of oxygen in arterial blood (PaO2) less than 8 kPa or new onset oxyhaemoglobin saturation measured by pulse oximetry (SpO(2)) less than 90% whilst breathing room air that required conventional oxygen therapy, noninvasive or invasive mechanical ventilation. RESULTS PRF developed in 224 patients (4.2% of the 5384 patients studied). In-hospital mortality [95% confidence interval (95% CI)] was higher in patients who developed PRF [10.3% (6.3 to 14.3) vs. 0.4% (0.2 to 0.6)]. Regression modelling identified a predictive PRF score that includes seven independent risk factors: low preoperative SpO(2); at least one preoperative respiratory symptom; preoperative chronic liver disease; history of congestive heart failure; open intrathoracic or upper abdominal surgery; surgical procedure lasting at least 2 h; and emergency surgery. The area under the receiver operating characteristic curve (c-statistic) was 0.82 (95% CI 0.79 to 0.85) and the Hosmer-Lemeshow goodness-of-fit statistic was 7.08 (P = 0.253). CONCLUSION A risk score based on seven objective, easily assessed factors was able to predict which patients would develop PRF. The score could potentially facilitate preoperative risk assessment and management and provide a basis for testing interventions to improve outcomes. The study was registered at ClinicalTrials.gov (identifier NCT01346709)
