ABSTRACT Transfemoral transcatheter aortic valve replacement (TAVR) is currently the standard catheter-based treatment of severe aortic stenosis patients. Being the transfemoral route not feasible, other access sites could be chosen. Transaortic TAVR via either a J mini-sternotomy or a right anterolateral mini-thoracotomy is a good option for patients having tricky thoracoabdominal aorta. Some tips and tricks may help in getting a fast and safe transaortic procedure.

RESUMO O objetivo deste estudo foi caracterizar a produção de um carvão de caroço de pêssego e também avaliar a adsorção de corantes têxteis pelo carvão ativado de caroço de pêssego. A ativação do carvão foi realizada utilizando cloreto de zinco como agente oxidante. O carvão ativado foi então utilizado na adsorção de corantes, para posterior aplicação no tratamento de um efluente têxtil. Primeiramente, realizou-se a produção de carvão ativado com as temperaturas de 500, 700 e 900°C e tempo de carbonização de 10 15 e 20 minutos e verificou-se a remoção dos corantes preto reativo 5 e azul de metileno. De acordo com a metodologia de superfície de resposta, a melhor temperatura de produção apresentou-se acima de 700°C com tempo de exposição de 10 minutos para os dois corantes. Desse carvão ativado, avaliaram-se os dados de densidade, teor de umidade e cinzas, pH e rendimento. Também foram realizados ensaios cinéticos e de equilíbrio. Os dados foram ajustados a três modelos cinéticos. As medidas para determinação da eficiência na remoção de cor do efluente têxtil foram realizadas pelo método espectrofotométrico e demonstraram média de remoção superior a 62% da cor presente no efluente bruto. Desse modo, o caroço de pêssego demonstrou elevado potencial para a produção de carvão ativado visando o tratamento de efluentes contendo corantes, podendo servir como alternativa de baixo custo.

ABSTRACT The aim of this study was to characterize the production of activated charcoal from the peach kernel and assess the adsorption of textile dyes by this activated charcoal. The activation of the charcoal was performed using zinc chloride as the oxidizing agent. The activated charcoal was then used in the adsorption of dyes for later application in the treatment of a textile effluent. Firstly, the production of activated carbon was carried out at temperatures of 500, 700, and 900°C and carbonization time of 10, 15, and 20 minutes and the removal of the Reactive Black 5 and Methylene Blue dyes was verified. According to the methodology of response surface, the best production temperature was above 700°C with 10 min exposure for both dyes. From this activated carbon, data on density, moisture and ash content, pH, and yield were evaluated. Kinetic and equilibrium tests were also performed. The data were fitted to three kinetic models. The measures to determine the efficiency in the color removal of the textile effluent were carried out by the spectrophotometric method and demonstrated an average removal greater than 62% of the color present in the raw effluent. In this way, the peach kernel demonstrated a high potential for the production of activated carbon aiming at the treatment of effluents containing dyes and can serve as a low cost alternative.

Abstract The mucopolysaccharidosis (MPS) disorders are a group of rare, inherited lysosomal storage disorders. In each of the 11 MPS (sub)types, deficiency in a specific lysosomal enzyme (1 of 11 identified enzymes) leads to accumulation of glycosaminoglycans, resulting in cell, tissue, and multi-organ dysfunction. There is great heterogeneity in the clinical manifestations both between and within each MPS type. Somatic signs and symptoms include short stature, coarse facial features, skeletal and joint abnormalities, cardiorespiratory dysfunction, hepatosplenomegaly, and vision and hearing problems. In addition, patients with MPS I, II, III, and VII can have significant neurological manifestations, including impaired cognitive, language, and speech abilities, behavioral abnormalities, sleep problems, and/or epileptic seizures. Hydrocephalus is a frequent finding in patients with MPS I, II, and VI. Spinal cord compression can develop in almost all MPS disorders. Effective management and development of therapies that target these neurological manifestations warrant a profound understanding of their pathophysiology and progression in the different MPS types and best practices for evaluation and treatment. In order to obtain expert opinion addressing these topics we performed an online survey among an international group of experts with extensive experience in managing and treating MPS disorders. The results of this survey provide important insights into the management of neurological manifestations of MPS in clinical practice and are a valuable addition to current evidence.

Background and Objectives: Neuroimaging studies have found higher rates of white matter hyperintensities (WMHs) in patients with bipolar disorder (BD) of all ages, although whether BD is associated with increased rates of WMHs independently from age and cerebrovascular risk factors is still matter of debate. The outcome of BD associated with severe WMHs is generally poor, but several authors have suggested that some factors could have a protective role in BD. The aim of the present study was to report the two-year follow-up of a woman with BD type I and severe WMH/PWMH lesions who was taking high concentrations of vitamin-D in her nutrition, as well as taking lithium and haloperidol as treatment. Case presentation: A 76-year-old woman was hospitalized for a mixed state BD. She had severe WMHs. She took lithium and haloperidol during the hospitalization and was euthymic at discharge as well as after two-years of follow-up. Her nutrition had a high concentration of Vitamin-D. Unfortunately, it was not possible to give her a second MRI. Conclusions: Although there was probable persistence of WMHs, the patient improved in both mood and quality of life. The possible protective effect of lithium and Vitamin-D is discussed.
