Inspeção de Precaução de Contato: relato de Experiência de uma Graduanda de Enfermagem Botucatu

Infections Related to Healthcare (IRAS) is a problem of worldwide concern, responsible for much morbidity and lethality. The incidence of IRAS associated with resistant microorganisms has increased worldwide. It is also known that the etiology of bacterial resistance is multifactorial, thus controlling the spread of resistant microorganisms requires the implementation of control measures that involve the performance of standard and contact precautions, plus the use of antimicrobials. To diagnose the problem as to the likely accession of the measures of infection control was prepared in a form to inspect the practices of the health staff acting with patients in contact precautions. The inspections had an educational and awareness, no punitive measures were taken to staff as warnings, suspensions or complains of a breach of ethics. If any irregularities were found, the professional standards of care countershaft contact and the nurse responsible for the head nurse or unit area were notified and counseled about the correct practice of isolation. While an undergraduate student initiated precautionary inspections of contact in order to verify the actual use of isolation measures, since the professionals were unaware of my active participation in the Committee on Infection Control. Facilities and difficulties were encountered in the process, and from the inspections was possible interventions to facilitate compliance with standards for isolation imposed by contact. Since the instrument has significantly improved adherence to contact isolation practices, the members of the Infection Control regulated inspections and intend to use it as a permanent method

Desenvolvimento e avaliação das atividades antioxidante e despigmentante in vitro de emulsões múltiplas a/o/a contendo dipalmitato kójico

Currently, there has been a growing concern for men and women with the appearance of the face and body, driven primarily by aesthetic standards set by the media. For this, the pharmaceutical and cosmetic industries have conducted numerous research projects aiming at the development of formulations that mitigate the aging and some skin disorders such as hipercromies. One of the most frequent pathologies of skin is melasma, a manifestation of hyperpigmentation caused by hipermelanogenesis symmetrical and progressive, caused usually by hormonal irregularities, exposure to sunlight and genetic factors. In addition to sunscreen, the treatment is indicated the use of depigmenting substances, among them the kojic dipalmitate (DK), which is cleaved into kojic acid (5- hydroxy-2-hydroxy-methyl-4H-piran-4-one) by esterase after absorption by the skin cells. The kojic acid inhibits the action of tyrosinase as a chelator of ions and promotes the reduction of eumelanin and its precursor monomer. To promote a controlled release and improve the stability of the system, the DK can be incorporated into multiple emulsions, that is, complex systems composed of two emulsifications, where the two types of emulsions (W/O and O/W or O/W and W/O) exist simultaneously, forming emulsions of type W/O/W or O/W/O. This work aimed to incorporate the DK in emulsion W/O/W, physical-chemical systems obtained and to evaluate the antioxidant and depigmenting action in vitro of the developed formulations. The physico-chemical characterization was performed by microscopic analysis, quantification and size distribution, determination of pH, conductivity, zeta potential and bioadhesive test of the formulations. The droplet size in accordance with the use of light microscopy and dynamic light scattering is approximately 1μm. The pH, electrical conductivity and bioadhesion have not changed with the addition... (Complete abstract click electronic access below)

Análise teórica e experimental de uma ventaneira de alto forno, visando seu comportamento térmico e fluidodinâmico

In this work, it was studied the thermal and fluid dynamic behavior from theorical and experimental point of view of a blast furnace tuyere. The tuyere is responsible for the hot air insuflation into the blast furnace. The parameter used in the comparison was the difference between the cooling water inlet and outlet temperatures. There were used forced convection correlations inside circular sections with adequations for non circular sections. Based on operations dates of flux and thermal loads it was possible to model numerically the tuyere, and, since it was obtained the wall temperatures, estimate the conduction and convection resistances and the heat flux through the walls in contact with the water. The total heat fluxes from wall to water were applied to the energy conservation equation where could be estimated the theorical temperature variation. Compared to the real value, the theorical value presented a difference of 0,2 °C. Considering that the boundary conditions around the tuyere are transitories and that your channels have some rugosity irregularities we can consider the estimation method for cooling system coherent with the real operational parameters

Manejo no incubatório que afeta a eclodibilidade de ovos de galinha (Gallus Gallus Domesticus)

In the process of artificial incubation of fertile eggs of chicken (Gallus gallus domesticus) there are procedures that, they are not hindered the birth, they cause embryonic mortality. Handlings before incubation as disinfection and storage are capable to reduce the embryonic if accomplished of inadequate way viability. Already in the incubation process properly says, irregularities in variables as temperature, turning, humidity and ventilation in the incubator reduce the hatchability, what means that, of the total of fertile eggs there is reduction in the number of born chicks, there is like this the reduction of profit of the incubator, being necessary an analysis of which they interfered in the birth

Concentração de tensões em peças e componentes estruturais - uma abordagem através do método dos elementos finitos

Any failure process that may occur in a part probably is located where the stress exceeded the level of resistance. When a part or component has a sharp change in geometry, such as slots, holes, grooves, bumps or other irregularities, there is an increased concentration of stress at a specific location of the part. The objective of this study is to determine the maximum stresses in structural parts and components using the equations of elasticity theory in conjunction with the stress concentration factor experiment and compare them with results obtained by finite element method

Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups

Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This article presented and discussed the indications and limitations of enamel microabrasion treatment. Three case reports treated by enamel microabrasion were also presented after 11, 20 and 23 years of follow-ups.

Análise estrutural em relictos de cerrado no parque estadual do Guartelá, município de Tibagi, estado do Paraná, Brasil

This study was accomplished in existing Cerrado's relicts at State Park Guartelá, Tibagi, PR (24°39'10S and 50°15'25W), which represent one of the last extreme-meridional remanescents of this type of formation. Fifty plots with dimensions of 5x5m were allocated for phyto-sociological analysis, including in the sample individuals with height ≥ 1 m, divided into two samples to evaluate the following strata: a) upper-plants with DAS ≥ 3 cm, and b) intermediate - plants with DAS <3cm. Moreover, in each plot, there were established sub-plots with dimensions of 1x1m for sampling the lower stratum, comprised by individuals with height <1m and >10cm. The complete survey found 1340 individuals distributed in 28 families, 66 genera and 115 species. The diversity index was higher for the mean component (H'=3.30), followed by the superior component (H'=3.09) and the inferior (H'=2.91). The frequent occurrence of bushes is a remarkable characteristic of the physiognomy of the areas inside the park and 82 % of the populations studied are distributed in aggregated standard. Because it is a marginal region of occurrence of cerrado vegetation, now under the influence of a subtropical climate, more humid and cold, compared to the core area of this biome, it is noted that these areas are characterized by a decrease in stature, richness and diversity of its flora. Nevertheless, they preserve typical species of the Brazilian Savannah; but, due to their distribution in relicts and been, in part, devastated, some are included in the red list of endangered plants in Parana state, which evidences the importance of conservation and management of these areas.

Desenvolvimento do rúmen de bovinos no período pré-natal

The development of the domestic mammals’ stomach is a complex process, especially in ruminants. The objective of this research was to perform the analysis of structures of this organ during prenatal period. Samples of Nelore fetuses rumen (Bos Taurus indicus) were divided into five groups: 1 - fetuses with 9 to 15 weeks (8 to 21cm) of gestation, 2 - fetuses with 16 to 22 weeks (23 to 37cm), 3 - fetuses at 23 to 29 weeks (40 to 58cm) 4 - fetuses with 30 to 36 weeks (61 to 77cm) and 5 - fetuses with 37 to 43 weeks (79 to 88cm). Sections were stained with Hematoxylin and eosin and Mallory's trichrome and examined at light microscope. In group 1, in fetuses with 11 cm, could be seen all the layers, mucosa with high epithelium and light cells, lamina propria fused with submucosa, the muscular layer was with two thin sublayers similar in thickness and serosa was thin too. With 13.5 cm, was observed the first irregularities in the mucosa with epithelium projections and lamina propria that will lead rumen papillae. With 16.5 cm there was differentiation of the lamina propria to the submucosa. In group 2, in fetuses with 28 cm were observed complete papillae. From this stage, the remaining groups, there was an increase in thickness of the epithelium, lamina propria, submucosal and muscular layer whit the inner sublayer more thicker than the external and serosa. It was concluded that the main variations occur in fetuses of groups 1 and 2, and after this phase, there is increased in thickness of all layers until the end of the pregnancy period.
