Many faunal assemblages across southwest Asia contain the remains of multiple wild equid species, which may reflect individual prehistoric human populations' use of different hunting and/or landscape exploitation strategies. Accurate equid species assignments are therefore important. This paper tests the extent to which zooarchaeologists agree on equid species assignments made using commonly used zooarchaeological dental identification criteria. Seven zooarchaeologists individually use published criteria to assign species to equid teeth from Neolithic Çatalhöyük in central Anatolia, then use Fleiss' kappa to measure our reliability of agreement. We assess our degrees of agreement for species assignments made using scanned images versus actual specimens and for mandibular teeth versus maxillary teeth. Having failed to achieve significant agreement, we conclude that zooarchaeologists should be cautious about species assignments made using these methods.

RationaleHigh blood pressure (BP) is common in acute stroke and is associated with poor outcome. Previous hospital-based trials testing the effects of BP lowering on functional outcome have been inconclusive. The PIL-FAST and RIGHT pilot trials confirmed the feasibility of performing single-centre ambulance-based stroke trials in the UK. In both RIGHT and a subgroup of patients recruited within 6 hours into the large ENOS trial, transdermal glyceryl trinitrate (GTN), a nitric oxide donor, lowered BP and reduced death or disability. Based on these results, RIGHT-2 aims to test the safety and efficacy of transdermal GTN in the pre-hospital setting.MethodsParamedics from 7 UK ambulance services serving 40 comprehensive or primary stroke care centres will screen, consent, randomise and treat 850 patients presenting within 4 hours of FAST-positive stroke and with systolic BP >120 mm Hg. Treatment will comprise GTN or similar sham patch, and will be continued in hospital for 3 days. The primary outcome will be the modified Rankin Scale at day 90. Secondary outcomes include vascular events, disability, quality of life, mood and cognition. Neuroimaging and biomarkers will examine potential mechanisms of action.StatusRecruitment commenced in October 2015. Challenges with the trial and baseline characteristics of the first recruited patients will be presented.FundingBritish Heart Foundation.

Aims and method The authors designed and delivered simulation training to improve the confidence and competence of junior doctors beginning work in psychiatry. Junior doctors completed various simulated psychiatry scenarios while receiving personalised feedback and teaching from their peers in online or socially distanced settings. Learners rated their confidence in psychiatry skills pre- and post-session, and Wilcoxon signed-rank tests were conducted to detect statistically significant differences. Qualitative feedback was analysed thematically. Results Twenty-one junior doctors attended the training. There were statistically significant (P < 0.05) improvements in trainee confidence across all psychiatry skills tested. The most enjoyable aspects of the session included its ‘interactivity’, relevance to clinical practice, and ‘realistic’ and ‘interesting’ simulated scenarios. Clinical implications Near-peer simulation teaching, delivered both in person and online, is effective at improving junior doctors’ confidence in psychiatry. Delivering this training during placement induction could help to ensure adequate preparation of, and support for, new doctors.
