Medical identification or alert jewellery: an opportunity to save lives or an unreliable hindrance?
Medical identification jewellery can convey vital information to emergency responders, but mistakes and ambiguity may lead to misdiagnosis and morbidity. We performed a review of relevant articles retrieved from Pubmed® , Embase® and Scopus® and Google UK Inc. to investigate the commercial availability and issuance of these products. From 84 identified studies, we shortlisted 74 for review. ⋯ The accuracy and appropriateness of this information may thus vary. In the absence of national guidance in the UK, we suggest that there should be a list of specific indications warranting their use, a requirement for regular review of information, and clarity around the level of physician input into the engraving chosen. We discuss the potential benefits vs. risks of wearing medical alert jewellery and clarify the limitations of medical teams' responsibilities in relation to patients found to be wearing them.

There is disagreement regarding the benefits of goal-directed therapy in moderate-risk abdominal surgery. Therefore, we tested the hypothesis that the addition of non-invasive cardiac index and pulse pressure variation monitoring to mean arterial pressure-based goal-directed therapy would reduce the incidence of postoperative complications in patients having moderate-risk abdominal surgery. In this pragmatic multicentre randomised controlled trial, we randomly allocated 244 patients by envelope drawing in a 1:1 fashion, stratified per centre. ⋯ Overall complication rates were similar (42/94 (44.7%) vs. 38/81 (46.9%) in the control and CI-PPV groups, respectively; p = 0.95). The CI-PPV group had lower mean (SD) pulse pressure variation values (9.5 (2.0)% vs. 11.9 (4.6)%; p = 0.003) and higher mean (SD) cardiac indices (2.76 (0.62) l min-1 .m-2 vs. 2.53 (0.66) l min-1 .m-2 ; p = 0.004) than the control group. In moderate-risk abdominal surgery, we observed no additional value of cardiac index and pulse pressure variation-guided haemodynamic therapy to mean arterial pressure-guided volume therapy with regard to postoperative complications.

Sarcopenia is the degenerative loss of core muscle mass. It is an aspect of frailty, which is associated with increased rates of peri-operative harm. ⋯ In multivariate analysis, mortality hazard (95%CI) was independently associated with: age, 1.06 (1.01-1.13) per year, p = 0.03; and the adjusted area of the left psoas muscle, 0.94 (0.81-1.01) per mm2 .kg-0.83 , p = 0.08. Shortened hospital stay was independently associated with haemoglobin concentration and adjusted left psoas muscle area, hazard ratio (95%) 1.01 (1.00-1.02) per g.l-1 and 1.05 (1.02-1.07) per mm2 .kg-0.83 , p = 0.04 and 0.001, respectively.
