ABSTRACT Chimeric antigen receptor T-cells (CAR-T cells) are a new modality of oncological treatment which has demonstrated impressive response in refractory or relapsed diseases, such as acute lymphoblastic leukemia (ALL), lymphomas, and myeloma but is also associated with unique and potentially life-threatening toxicities. The most common adverse events (AEs) include cytokine release syndrome (CRS), neurological toxicities, such as the immune effector cell-associated neurotoxicity syndrome (ICANS), cytopenias, infections, and hypogammaglobulinemia. These may be severe and require admission of the patient to an intensive care unit. However, these AEs are manageable when recognized early and treated by a duly trained team. The objective of this article is to report a consensus compiled by specialists in the fields of oncohematology, bone marrow transplantation, and cellular therapy describing recommendations on the Clinical Centers preparation, training of teams that will use CAR-T cells, and leading clinical questions as to their use and the management of potential complications.

Group B streptococci (GBS) infections occur worldwide. Although serotyping has been used for epidemiologic purposes, this does not accurately characterize enough members of a genetically heterogeneous bacterial population. The aims of this work were to evaluate the genetic diversity of 45 type Ia GBS strains isolated in Brazil by pulsed-field gel electrophoresis as well as to evaluate antimicrobial susceptibility profiles and identify virulence genes. Twenty-four strains were assigned to cluster A. All strains under study contained the hylB and scpB genes. The bca gene was detected in only 10 strains and none of the streptococci carried the bac gene. Thirty-nine strains were resistant to tetracycline.

Para se exportar, é necessário não só atingir padrões de qualidade exigidos pelo país importador, mas também padrões fitossanitários. A irradiação tem como principal função o controle quarentenário de moscas-das-frutas, portanto é necessário que se associe a tratamentos que visem à manutenção da qualidade do fruto. O objetivo deste trabalho foi avaliar a qualidade dos mamões submetidos à imersão em água quente seguidos de irradiação em doses de tratamento quarentenário. Os mamões verdes selecionados foram submetidos aos seguintes tratamentos: a) controle; b) 250 Gy; c) 500 Gy; d) choque térmico (60º C por 30 segundos); e) 250 Gy + choque térmico, e f) 500 Gy + choque térmico. Os mamões foram armazenados a 21±1ºC e umidade relativa de 85-90%, e, após 8 dias, foram avaliados quanto ao teor de sólidos solúveis, pH, acidez titulável, firmeza, índice de doenças e coloração interna. As análises de perda de massa e coloração externa foram realizadas a 0; 2; 4 e 7 dias após a irradiação. Foi observado nos frutos submetidos a choque térmico (d, e, f) quantidade menor de sintomas de antracnose e podridão peduncular e, nos tratamentos combinados (e, f), foi verificada manutenção da firmeza do mamão. Somente no segundo dia os frutos irradiados (b, c, e, f) estavam mais amarelados que os demais. Para os demais parâmetros avaliados, não houve diferença entre os tratamentos.

To export, it is not only necessary to achieve quality standards, but also, phytosanitary standards. The main function of irradiation is quarantine control of fruit flies, therefore it is necessary to combine with treatments which focus at keeping fruit quality. The objective of this work was the evaluation of the quality of papaya submitted to irradiation and heat shock treatment through immersion in hot water. Green papayas selected were submitted in the following treatments: a) control, b) 250 Gy, c) 500 Gy; d) heat shock (60ºC for 30 seconds), e) 250 Gy + heat shock and f) 500 Gy + heat shock. The papayas were stored at 21 ±1ºC with relative humidity of 85-90%, and then after 8 days, they were evaluated by their soluble solid content, pH, titratable acidity, firmness, decay index and internal color. The analysis of fresh matter loss and external color were executed at 0, 2, 4 and 7 days after irradiation. It was observed that in treatments submitted to hot water (d, e, f) decay was controlled and in combined treatments (e, f) it was verified higher firmness. In the second day, irradiated treatments (b, c, e, and f) were yellower than the others. As to the other factors evaluated, there were no differences between treatments.
