We sought to investigate the referral pattern and determine whether the presence of significant coronary artery disease (CAD) has increased in this particular patient cohort. We performed a retrospective study, reviewing all young patients who undergone computed tomography coronary angiography (CTCA) six months prior to the NICE update and compared this to an identical time frame one year after the updated NICE guidelines. Methods: We performed two searches on Picture Archiving and Communication System (PACS) system (SECTRA AB, Sweden) to retrieve all patients under the age of 45 who had been referred to our Department for CTCA for chest pain of recent onset. The first group included a cohort of patients who underwent CTCA within a period of six months before the updated recommendations. The second group included patients that were scanned a year after the implementation of the updated NICE guidance. The following data was collected and processed: demographics, referral sites, clinical indication, risk factors, radiation dose, scan protocol, presence and severity of disease. A comparison was made between these two datasets and the impact of the change in guidelines was evaluated. Results: In total, 687 patients underwent CT coronary

A preliminary data set of 7 illicit drug samples and a possible cutting agent has been collected with a range of count times using a tungsten target X-ray source, a high resolution HpGe detector and a variable geometry diffraction cell. These results have been used to calibrate and train multivariate analysis software to predict the drug content in previously unseen spectra.

Given that thousands of parcels from abroad pass through both Royal Mail and private sorting offices daily, manual searching of all, or even a significant proportion, of them, is ...
