ABSTRACT Sporotrichosis is the most frequent subcutaneous mycosis in Latin America. It is caused by species of the genus Sporothrix. Infection in humans occurs through the entry of the fungus into the skin. Zoonotic outbreaks involving cats in the transmission of the disease have been frequently reported. The lymphocutaneous form is the most commonly observed and the upper limbs are the most affected sites. We report a case of a 64-year-old healthy female patient with a lymphocutaneous form with rapid progression of lesions, which was refractory to initial treatment with itraconazole. Treatment with liposomal amphotericin B was performed with a satisfactory resolution, but aesthetic and functional sequelae in the left upper limb were installed.

Resumo Este artigo examina o contexto e as implicações da pandemia por Covid-19 na cidade de Belo Horizonte (BH) nos primeiros 80 dias da doença. Utilizamos um recorte analítico descritivo para mensurar a evolução dos casos, o excesso de óbitos, a taxa de transmissibilidade do vírus e a pressão da doença sobre o sistema de saúde de BH e região, através da taxa de ocupação hospitalar nos leitos públicos. Além disso, identificamos as principais políticas de contenção adotadas pelas autoridades locais, bem como as implicações da redução do distanciamento social. Nossos resultados demonstram que o Sistema Único de Saúde (SUS), bem gerido, é fundamental para o enfrentamento da pandemia e a mitigação de suas consequências para a população. O processo de flexibilização que se inicia tem imposto novos desafios que requererão monitoramento atento das autoridades e da sociedade.

Abstract The paper examines the implications of Covid-19 pandemic for the city of Belo Horizonte (BH), during the first 80 days of the disease. We use a descriptive-analytical approach to estimate the growth of Covid-19 cases over time, the excess of deaths, the virus’ rate of transmissibility, and the consequent burden on the municipal the health system, measured by the rate of occupancy of public hospital beds. Also, we identify the main containment policies adopted by local authorities, and the implications of reopening measures and the following reduction of social distancing. Our findings reveal that a well-managed Unified Health System (SUS) is paramount to effectively tackle the pandemic and its consequences for the population. The reopening process has imposed new challenges that will require close monitoring by the authorities and by the society.

This work evaluates the effect of ZnCl2 and Zn(NO3)2.6H2O as precursors in the synthesis of ZnO nanocrystals. The materials were obtained at 90 ºC by a simple solochemical route. The resulting samples were characterized regarding phase composition, particle size and morphology, by means of XRD and TEM. The analysis have provided evidences that the material obtained applying Zn(NO3)2.6H2O as precursor has hexagonal crystalline structure, typical of the ZnO, and dimensions in the nanoscale. However, applying ZnCl2 as precursor results in a mixture of ZnO and Zn5(OH)8Cl2.H2O phases. For both precursors, the predominant morphology of the obtained ZnO nanocrystals was the rod-like structure.

Objetivou-se com este trabalho avaliar o efeito do peso sobre as relações das medidas de comprimento padrão de tilápias-do-nilo (Oreochromis niloticus). Avaliaram-se as medidas: comprimento da cabeça; altura do corpo, medida à frente do 1° raio das nadadeiras peitoral, dorsal, anal e caudal; largura do corpo, medida à frente da inserção do 1º raio das nadadeiras peitoral, dorsal e anal; perímetro, medido à frente da inserção do 1° raio das nadadeiras peitoral, dorsal e anal; e menor circunferência do pedúnculo; e os rendimentos de carcaça, filé, cabeça, nadadeira, pele, vísceras e resíduos. Foram utilizados 80 tilápias, em delineamento inteiramente casualizado com quatro tratamentos (faixas de peso 250 a 300 g; 350 a 400 g; 450 a 500 g, 550 a 600 g) e 20 repetições, considerando o peixe a unidade experimental. As menores variações nas características morfométricas foram observadas na faixa de peso de 450 a 600 g em comparação à faixa de 250 a 400 g. Nas faixas de peso 250 a 300 g, 350 a 400 g, 450 a 500 g e 550 a 600 g, não houve diferenças nos rendimentos de carcaça e filé e nas porcentagens de cabeça, nadadeira, pele e resíduos. A porcentagem de vísceras na faixa de peso 550 a 600 g (10,98%) foi significativamente inferior à obtida nas faixas de 250 a 300 g (12,77%), 350 a 400 g (13,26%) e 450 a 500 g (12,69%). O peso do filé na faixa de peso 350 a 400 g (260,50 g) foi superior ao da faixa de 250 a 300 g (239,95 g). Não houve diferença no peso do filé entre as faixas de peso 450 a 500 g (284,20 g) e 550 a 600 g (292,80 g). As faixas de peso de 450 a 500 g e 550 a 600 g apresentaram valores superiores de peso do filé em comparação às de 250 a 300 g e 350 a 400 g. Considerando o peso do filé, o peso ideal de abate da tilápia é de 450 a 500 g no intervalo de peso de 250 a 600 g.

The objective of this study was to evaluate the effect of weight categories on the relation of the measures of standard length; length of the head; height of the body measured at the front of the 1° ray of pectoral, dorsal, anal and tail fins; width of the body measured at the front of the insertion of 1º ray of pectoral, dorsal and anal fins; perimeter measured at the front of the insertion of the 1° ray of pectoral, dorsal and anal fins and minor circumference of the peduncle and yield of carcass, filet, head, fin, skin, viscera and residues of the Nile tilapia (Oreochromis niloticus). Eighty tilapia were used, in a completely randomized design, with four treatments (weight categories 250 the 300 g; 350 the 400 g; 450 the 500 g and 550 the 600 g) and 20 replications. Each fish was considered an experimental unit. The Nile tilapia presented minors variations in the morphometric characteristics in the weight category 450 to 600 g, when compared with the category 250 to 400 g. The weight category 250 the 300 g, 350 the 400 g, 450 the 500 g and 550 the 600 g provided the same yield of carcass, filet and percentages of head, fin, skin and residues. The percentage of viscera in the 550 the 600 g category (10.98%) was significantly lower when compared to 250 the 300 g (12.77%), 350 the 400 g (13.26%) and 450 the 500 g (12.69%). The weight of filet in the 350 the 400 g category (260.50 g) was higher than the 250 the 300 g category (239.95 g). There was no difference in the weight of fillet between the 450 the 500 g category (284.20 g) and 550 the 600 g (292.80 g). The category 450 the 500 g and 550 the 600 g presented higher values of weight of fillet when compared to 250 the 300 g and 350 the 400 g. According to the weight of fillet found, the ideal weight of slaughter of the tilapia is between 450 and 500 g in a range of 250-600 g.
