National Comprehensive Cancer Network Infusion Efficiency Workgroup Study: Optimizing Patient Flow in Infusion Centers.

Purpose: The National Comprehensive Cancer Network (NCCN) formed an Infusion Efficiency Workgroup to determine best practices for operating efficient and effective infusion centers.

Methods: The Workgroup conducted three surveys that were distributed to NCCN member institutions regarding average patient wait time, chemotherapy premixing practices, infusion chair use, and premedication protocols. To assess chair use, the Workgroup identified and defined five components of chair time.

Genomic catastrophes frequently arise in esophageal adenocarcinoma and drive tumorigenesis.

Oesophageal adenocarcinoma (EAC) incidence is rapidly increasing in Western countries. A better understanding of EAC underpins efforts to improve early detection and treatment outcomes. While large EAC exome sequencing efforts to date have found recurrent loss-of-function mutations, oncogenic driving events have been underrepresented.

Nicotinamide adenine dinucleotide phosphate reduced oxidase 5 (Nox5) regulation by angiotensin II and endothelin-1 is mediated via calcium/calmodulin-dependent, rac-1-independent pathways in human endothelial cells.

Rationale: Although Nox5 (Nox2 homolog) has been identified in the vasculature, its regulation and functional significance remain unclear.

Objectives: We sought to test whether vasoactive agents regulate Nox5 through Ca(2+)/calmodulin-dependent processes and whether Ca(2+)-sensitive Nox5, associated with Rac-1, generates superoxide (O(2)(*-)) and activates growth and inflammatory responses via mitogen-activated protein kinases in human endothelial cells (ECs).

Methods And Results: Cultured ECs, exposed to angiotensin II (Ang II) and endothelin (ET)-1 in the absence and presence of diltiazem (Ca(2+) channel blocker), calmidazolium (calmodulin inhibitor), and EHT1864 (Rac-1 inhibitor), were studied.
