The severe acute respiratory syndrome SARS-CoV-2 pandemic has posed significant challenges to hospital and public health systems in the United States. In response to a shortage in nasopharyngeal swabs, our institution developed, tested, and deployed 3D-printed swabs to obtain a specimen for testing. A patient was tested in preparation for a scheduled Esophagogastrodeuodenoscopy. During the procedure the swab broke and a portion remained in the superior meatus and olfactory cleft. This case study describes the process of locating and removing the broken sections of the 3D-printed swab. In response to this incident, 3D-printing teams test swabs for sample collection and …

Three-dimensional perfusion bioreactors have been shown to enhance cell viability and function through improved nutrient exchange. However, the ideal bioreactor scaffold geometry is still unknown. The focus of this study is to use computational fluid flow studies to inform bioreactor design. Specifically, we will model the effect of bioreactor design on fluid shear stress and then correlate these values with stem cell viability in the bioreactor. Previous studies have shown that the maximum shear stress level for the viability of human mesenchymal stem cells (hMSCs) is 0.3 dynes/cm2. Two distinct Computer Aided Design models were created consisting of …
