Happy New Year! This month we've got a New in EM looking at the use of neutrophil-lymphocyte ratios in septic arthritis and a discussion on specificity vs. sensitivity. Becky and Chris look at the new NICE guidance on subarachnoid haemorrhage and Rob talks for too long about it, and then we return to New Online with some new articles for your CPD. If you'd like to email us, please feel free to do so here.
