Water security threats and challenges following the rupture of large tailings dams.

The rupture of mine-tailings dams can severely contaminate rivers, because released tailings can interact with water for years keeping contaminant concentrations high. The general purpose of this study was to examine the rupture of B1 tailings dam in Ferro-Carvão stream (municipality of Brumadinho, state of Minas Gerais, Brazil), which occurred in 25 January 2019 and contaminated the main water course (Paraopeba River) with 2.8 Mm of metal-rich tailings.

Phagocytic activity of monocytes and neutrophils in patients with periodontitis, whether or not associated to type 2 diabetes.

Phagocytic functions by neutrophils/ monocytes and biochemical parameters were assessed in peripheral blood of patients with periodontitis, whether or not associated to type 2 diabetes, or patients with type 2 diabetes, or systemically healthy people. Fifty-eight participants were divided into four groups: Control - systemically and periodontally healthy patients (C, n=16), Periodontitis (P, n=14), Type 2 Diabetes (DM, n=11) and Periodontitis associated with type 2 diabetes (DMP, n=17). Blood samples were used to analyze phagocytic activity and the production of superoxide anion using optical microscopy.

Mechanical Periodontal Therapy Recovered the Phagocytic Function of Monocytes in Periodontitis.

Background: Several studies have focused on the association between periodontitis and systemic implications; however, the biological mechanisms of the immune responses before and after periodontal therapy involved in this relationship, such as phagocytic functions, remain unclear.

Objectives: This study aimed to investigate whether periodontal treatment improves the phagocytic function of blood monocytes in patients with severe periodontitis. .

Atomic Force Microscopy Is a Potent Technique to Study Eosinophil Activation.

Eosinophils are multifunctional cells with several functions both in healthy individuals, and those with several diseases. Increased number and morphological changes in eosinophils have been correlated with the severity of an acute asthma exacerbation. We measured eosinophils obtained from healthy controls and individuals with acute asthma using atomic force microscopy (AFM).

Expansion of the interprofessional clinical practice of Primary Care nurses.

Objective: To analyze the clinical practice of nurses in the interprofessional context of the Family Health Strategy.

Method: Case study in a basic health unit of the city of São Paulo with a professional team of the Family Health Strategy and of the Family Health Support Center. Direct observation and interviews with thematic analysis and triangulation were conducted.
