O objetivo deste estudo foi realizar uma revisão integrativa identificando como a técnica Delphi é utilizada nas pesquisas em Atenção Primária à Saúde. A quantidade de participantes, taxa de retorno, número de rodadas, duração, natureza dos questionários, forma de envio e nível de consenso, são itens da técnica Delphi que apresentaram variações entre os diferentes estudos. A técnica Delphi demonstrou ser uma ferramenta importante para ser utilizada em pesquisas referentes à Atenção Primária à Saúde, em especial, para cenários nos quais ainda não exista um número suficiente de evidências científicas que comprovem a efetividade de condutas ou procedimentos, tanto técnicos, quanto relacionais.

This research aimed to identify the generation of healthcare waste in hospitals in the city of Ribeirão Preto (SP). This is a descriptive and exploratory study conducted in 11 hospitals in the city. Data

Study on the prevalence of allergic respiratory diseases in schoolchildren between six and seven years old, associated with indicators of air pollution. A questionnaire based on the International Study of Asthma and Allergies in Childhood was administered to parents of students from public schools, located in urban areas with differing vehicle flows. There was a positive correlation between monthly frequency of rhinitis and concentration of pollutants, and negative with relative air humidity. Even with levels of air pollutants below that allowed by law, the prevalence of asthma, rhinitis and associated symptoms tended to be higher in the central region school, where there is heavy vehicular traffic.

Starch/polyester blends are potential substitutes for non‐degradable materials. Active food packaging was produced by the blown‐extrusion of starch/poly (butylene adipate‐co‐terephthalate) (PBAT) blends added to α‐tocopherol (α‐TOC). The films showed adequate stability and processability by the blown‐extrusion method and were converted into an essentially amorphous and homogeneous material. The transparency and water vapor permeability of the films increased with the addition of α‐TOC. The antioxidant interfered in the organization of the polymeric matrix, which was confirmed by SEM images, resulting in lower tensile strength and elongation at break, with no interference due to the α‐TOC concentration. The inclusion of α‐TOC did not influence the thermal stability, and it increased the crystallinity of the samples. The formulation with the lowest concentrations of the antioxidant (T0.25) presented an almost complete release of α‐TOC, proving the efficiency of the films as active packaging. The complete degradation of the materials was proved by evaluating the composting of the films. The eco‐friendly films are promising materials for active food packaging.

it is recommended for the health managers to focus on this issue. The lack of studies with regard to MPC also indicates the need for further studies on the waste management.
