Nurse-Driven Catheter-Associated Urinary Tract Infection Reduction Process and Protocol: Development Through an Academic-Practice Partnership.

Translating evidence-based practices to the bedside can be facilitated by an active academic-practice partnership between nursing faculty and frontline nursing staff. A collaborative effort between the university's academic nurses and the medical center's clinical nurses explored, created, implemented, and evaluated an evidence-based nurse-driven protocol for decreasing the rate of catheter-associated urinary tract infections. The nurse-driven protocol was piloted in 4 intensive care units and included nurse-driven orders for catheter discontinuation, utilization of smaller bore urinary catheters, addition of silver-based cleansing products for urinary catheter care, and education of staff on routine catheter care and maintenance.

RNA sequencing of pancreatic circulating tumour cells implicates WNT signalling in metastasis.

Circulating tumour cells (CTCs) shed into blood from primary cancers include putative precursors that initiate distal metastases. Although these cells are extraordinarily rare, they may identify cellular pathways contributing to the blood-borne dissemination of cancer. Here, we adapted a microfluidic device for efficient capture of CTCs from an endogenous mouse pancreatic cancer model and subjected CTCs to single-molecule RNA sequencing, identifying Wnt2 as a candidate gene enriched in CTCs.

Isolation of circulating tumor cells using a microvortex-generating herringbone-chip.

Rare circulating tumor cells (CTCs) present in the bloodstream of patients with cancer provide a potentially accessible source for detection, characterization, and monitoring of nonhematological cancers. We previously demonstrated the effectiveness of a microfluidic device, the CTC-Chip, in capturing these epithelial cell adhesion molecule (EpCAM)-expressing cells using antibody-coated microposts. Here, we describe a high-throughput microfluidic mixing device, the herringbone-chip, or "HB-Chip," which provides an enhanced platform for CTC isolation.
