"We Have All This Knowledge to Give, So Use Us as a Resource": Partnering with Adolescent and Young Adult Cancer Survivors to Determine Consumer-Led Research Priorities.

Purpose: Involvement of adolescent and young adult (AYAs) cancer survivors as consumers in research is increasingly encouraged, yet few studies have identified the feasibility and acceptability of methods used to involve them. We aimed to identify: (1) How feasible and acceptable is a consumer-driven, workshop-based research priority-setting approach? And (2) what research priorities do Australian AYA consumers endorse? Methods: AYA cancer survivors diagnosed 15-30 years old and currently younger than 35 years were invited to participate. The AYAs completed a pre-workshop survey to rank their top three priorities from the United Kingdom-based James Lind Alliance list, participated in a 90-minute focus group, and completed a post-workshop evaluation survey. We assessed the workshop feasibility by reviewing considerations, challenges, and enablers of success in the planning and conduct processes. Acceptability was assessed through participants' evaluation surveys and facilitators' informal reflections. The top three priorities were determined from pre-workshop surveys and focus group data. Results: Six survivors participated (M age = 24.2 years, M = 5 years post-treatment, 83% female). All reported that the workshop was an acceptable way to engage with researchers. Costs and recruitment challenges limited the workshop's feasibility. The AYAs' top priority was: What psychological support package improves psychological well-being, social functioning, and mental health during and after treatment?Discussion: The AYA survivors found our workshop to be an acceptable way to engage in research priority-setting. However, the feasibility of this approach depends on the resources available to researchers. Future research is needed to define the optimal method of engagement: What is most acceptable for AYAs and feasible for researchers?

Blood protein purification and simultaneous removal of nonenveloped viruses using tangential-flow preparative electrophoresis.

Gradiflow is new technology allowing purification of important blood proteins from viral contaminated plasma. Protein purification is based on unique scalable tangential-flow preparative electrophoresis, and is distinct from current technology because protein purification and virus removal are performed in the same step. This one-step removal and purification exploits both the size and charge of target proteins. The medically important blood proteins, immunoglobulin G (IgG) and alpha-1-antitrypsin, were chosen to demonstrate the ability of this process to purify proteins from contaminated plasma. Clearance factors achieved by infectivity assays and polymerase chain reaction (PCR) that meet regulatory requirements demonstrated removal of canine parvovirus (CPV). CPV is a model virus for pathogenic nonenveloped viruses, including parvovirus B19, not adequately removed or inactivated by most processes currently in practice. The recovery of proteins from plasma with high purity, recovery, and function, while simultaneously removing viruses, provides blood products with a level of purity compatible with clinical use more quickly and cheaply than available techniques.
