A model for in vitro evaluation of overlapping connections between devices used in the endovascular repair of popliteal aneurysms
This work proposes a new methodology to investigate the potential for disconnection (Type III
endoleak) of pairs of overlapped endoprostheses in a popliteal model vessel after a cyclic
physiologic load, for three different overlap lengths. A multiaxial fatigue accelerated testing
was designed to mimic the physiological loads and movements to which the peripheral arteries
are submitted during gait. The experiment design was based on principles from technical
standards ASTM F2477-07 and ASTM F2942-13. Migration and disconnection were
monitored by DIC (Digital Image Correlation) for three different overlap lengths (20, 30 and
40mm). The testing method proposed in this work was efficient to provide a simulated
environment to evaluate the influence of gait biomechanics on overlapped endoprosthesis
disconnection. Obtained results demonstrated minimal or absence of relevant migration
between the endoprosthesis, range -0.06 to 0,34 millimeters. The proposed methodology was
verified as a valuable tool to investigate the influence of the biomechanical environment which
the devices are subjected to on the migration of overlapped endoprosthesis. It may become a
new alternative to study the pre-clinical in vitro performance of single endoprosthesis or
multiple connected devices with different overlapped regions

Thinking about Race: The Salience of Racial Identity at Two- and Four-Year Colleges and the Climate for Diversity
Racial identity salience is an important component of identity development that is associated with a number of educational outcomes. Using the Diverse Learning Environments Survey, this study identifies precollege and college experiences that contribute to a heightened salience of racial identity, and its relationship to perceptions of campus climate

Prevenção e controle de infecção em unidade de terapia intensiva neonatal
Objetivou-se identificar o conhecimento da equipe de enfermagem de uma Unidade de Terapia Intensiva Neonatal(UTIN) sobre o controle de infecção, identificando os fatores que facilitam ou dificultam o controle e prevençãodas Infecções Relacionadas à Assistência a Saúde (IRAS). Estudo descritivo com abordagem qualitativa, realizadocom três enfermeiras e 15 técnicas de enfermagem, que atuam em uma UTIN de uma instituição filantrópica, naregião sul do Brasil. Evidenciou-se que a equipe de enfermagem possui grande conhecimento sobre os fatores quefacilitam a prevenção e controle das IRAS em UTIN, sendo o principal, a higienização das mãos. Entre os fatoresque dificultam o controle e prevenção, estão a superlotação e a excessiva carga de trabalho. A atuação eficiente equalificada da equipe de enfermagem constitui-se em estratégia de prevenção e controle das IRAS
