RESUMO

INTRODUCTION: Achieving a standard of clinical research at the pinnacle of the evidence pyramid is historically expensive and logistically challenging. Research collaboratives have delivered high-impact prospective multicentre audits and clinical trials by using trainee networks with a range of enabling technology. This review outlines such use of technology in the UK and provides a framework of recommended technologies for future studies. METHODS: A review of the literature identified technology used in collaborative projects. Additional technologies were identified through web searches. Technologies were grouped into themes including access (networking and engagement), collaboration and event organisation. The technologies available to support each theme were studied further to outline relative benefits and limitations. FINDINGS: Thirty-three articles from trainee research collaboratives were identified. The most frequently documented technologies were social media applications, website platforms and research databases. The Supportive Technologies in Collaborative Research framework is proposed, providing a structure for using the technologies available to support multicentre collaboration. Such technologies are often overlooked in the literature by established and start-up collaborative project groups. If used correctly, they might help to overcome the physical, logistical and financial barriers of multicentre clinical trials.

RESUMO

AIM: To present the initial 12 months of data of a straight-to-test (STT) computed tomography colonography (CTC) protocol as the first-line investigation for change in bowel habit (CIBH) and iron deficiency anaemia (IDA) in patients over 60 referred directly from primary care. MATERIALS AND METHODS: In 12 months, 1,792 STT CTC for IDA and CIBH were performed. No colonoscopies were performed as the primary investigation in this cohort. Data from this cohort were gathered prospectively. RESULTS: The colorectal cancer (CRC) detection rate was 4.9% and polyp detection rate was 13.5%. The CRC rate increased related to age (p=0.001), the CRC detection rate was 2.6% in patients aged 60-69 years, compared to 4.9%, 7.4%, and 11.4% in the 70-79, 80-89, and >90 years age groups. The CRC rate was higher in patients with IDA compared to CIBH (6.8% versus 3.9%, p=0.017). There were significantly more left-sided cancers (p=0.0165). Non-colonic cancers were found in 4.3% of patients and 6.8% had incidental findings that required further investigation and 11.9% had a new, potentially significant, incidental finding. CONCLUSION: These results are comparable to colonoscopy in terms of diagnostic accuracy and similar to those of CTC in published multicentre trials. This exciting model of care within radiology enables earlier testing, reduces waiting times, with fewer outpatient appointments, and results in good clinician and patient satisfaction.

RESUMO

We describe a one-pot strategy for the high yielding, operationally simple synthesis of fluorescent probes for Zn2+ that bear biological targeting groups and exemplify the utility of our method through the preparation of a small library of sensors. Investigation of the fluorescence behaviour of our library revealed that although all behaved as expected in MeCN, under biologically relevant conditions in HEPES buffer, a plasma membrane targeting sensor displayed a dramatic switch on response to excess Zn2+ as a result of aggregation phenomena. Excitingly, in cellulo studies in mouse pancreatic islets demonstrated that this readily available sensor was indeed localised to the exterior of the plasma membrane and clearly responded to the Zn2+ co-released when the pancreatic beta cells were stimulated to release insulin. Conversely, sensors that target intracellular compartments were unaffected. These results demonstrate that this sensor has the potential to allow the real time study of insulin release from living cells and exemplifies the utility of our simple synthetic approach.
