Integrating cancer survivors' experiences into UK cancer registries: design and development of the ePOCS system (electronic Patient-reported Outcomes from Cancer Survivors)
BACKGROUND: Understanding the psychosocial challenges of cancer survivorship, and identifying which patients experience ongoing difficulties, is a key priority. The ePOCS (electronic patient-reported outcomes from cancer survivors) project aims to develop and evaluate a cost-efficient, UK-scalable electronic system for collecting patient-reported outcome measures (PROMs), at regular post-diagnostic timepoints, and linking these with clinical data in cancer registries. METHODS: A multidisciplinary team developed the system using agile methods. Design entailed process mapping the system's constituent parts, data flows and involved human activities, and undertaking usability testing. Informatics specialists built new technical components, including a web-based questionnaire tool and tracking database, and established component-connecting data flows. Development challenges were overcome, including patient usability and data linkage and security. RESULTS: We have developed a system in which PROMs are completed online, using a secure questionnaire administration tool, accessed via a public-facing website, and the responses are linked and stored with clinical registry data. Patient monitoring and communications are semiautomated via a tracker database, and patient correspondence is primarily Email-based. The system is currently honed for clinician-led hospital-based patient recruitment. CONCLUSIONS: A feasibility test study is underway. Although there are possible challenges to sustaining and scaling up ePOCS, the system has potential to support UK epidemiological PROMs collection and clinical data linkage
Distribution and diel vertical movements of mesopelagic scattering layers in the Red Sea

an extreme environment due to low food concentrations,
high temperatures and low oxygen waters. Nevertheless, a
38 kHz echosounder identified at least four distinct scattering
layers during the daytime, of which the 2 deepest
layers resided entirely within the mesopelagic zone. Two of
the acoustic layers were found above a mesopelagic oxygen
minimum zone (OMZ), one layer overlapped with the
OMZ, and one layer was found below the OMZ. Almost all
organisms in the deep layers migrated to the near-surface
waters during the night. Backscatter from a 300 kHz lowered
Acoustic Doppler Current Profiler indicated a layer of
zooplankton within the OMZ. They carried out DVM, yet a
portion remained at mesopelagic depths during the night.
Our acoustic measurements showed that the bulk of the
acoustic backscatter was restricted to waters shallower than
800 m, suggesting that most of the biomass in the Red Sea
resides above this depth.This research is based in part on work
