Impact of the Nutritional Status on Clinical Outcomes of Patients with Coronavirus Disease Undergoing Cancer Treatment.

Coronavirus disease (COVID-19) is a critical and potentially fatal condition. The nutritional status affects the evolution and clinical outcome throughout the disease course among factors influencing the patient prognosis. In patients with cancer, the Patient-Generated Subjective Global Assessment (PG-SGA) is the preferred instrument for assessing the nutritional status.

Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Graft- versus -host disease.

The Brazilian Consensus on Nutrition in Hematopoietic Stem Cell Transplantation: Graft- versus -host disease was approved by Sociedade Brasileira de Transplante de Medula Óssea , with the participation of 26 Brazilian hematopoietic stem cell transplantation centers. It describes the main nutritional protocols in cases of Graft- versus -host disease, the main complication of hematopoietic stem cell transplantation.

Assembly of horseradish peroxidase within supported cationic bilayers.

The interaction between horseradish peroxidase (HRP) and dioctadecyldimethylammonium bromide (DODAB) bilayers supported on polystyrene microspheres (PSS) or on flat silicon wafers was evaluated from the following techniques: (1) dynamic light-scattering for determining size distributions, zeta-potentials and polydispersities for dispersions; (2) spectrophotometric determination of HRP concentration in supernatants of centrifuged mixtures; (3) in situ ellipsometry for mean thickness of deposited layers on wafers; (4) kinetics of product appearance for oxidation of 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid by H(2) O(2) in presence of free or immobilized enzyme. HRP incorporation (3.0 mg/m(2)) did not alter mean diameter and zeta-potential of PSS/DODAB particles but reduced enzyme activity by 50%, though activity persisted after several rinsing steps.
