We highlight the need for agreement on outcome definitions and for a minimum core outcome set to be measured and reported in hip fracture studies. This would strengthen the evidence-based approach to delivering optimal care.

Summary The 2001 Report of the National Confidential Enquiry into Perioperative Deaths recommended that an echocardiogram should be performed on patients with aortic stenosis prior to anaesthesia. In this study we present the patient details, management and outcome of the 272 hip fracture patients with a previously undiagnosed murmur and echocardiographically proven aortic stenosis admitted from 2001–2005 in our hospital. The patients with aortic stenosis were significantly older, and had significantly lower Abbreviated Mental Test Scores, than the control group of 3698 hip fracture patients without aortic stenosis. There were significant trends toward general anaesthesia over spinal anaesthesia, and use of invasive monitoring of blood pressure, as the severity of the aortic stenosis increased. There were no significant trends towards higher 30‐day or 1‐year mortality rates as the severity of the aortic stenosis increased. Resources for rapid pre‐operative echocardiograms should be made available for hip fracture patients as the results have significant implications for their subsequent anaesthetic management.

Goblet cell hyperplasia (GCH) and decreased ciliated cells are characteristic of asthma. We examined the effects of IL-13 (2 and 20 ng/mL) on in vitro mucociliary differentiation in pediatric bronchial epithelial cells (

Background: Perioperative studies of patients following hip fracture have large heterogeneity within their reported outcomes. This study aimed to develop a core outcome set for use in perioperative studies comparing the types of anaesthesia for hip fracture surgery. Methods: The consensus process consisted of a systematic review of the literature, three rounds of a Delphi survey, two consensus webinars, and face-to-face patient meetings. Results: The Delphi participants represented nine stakeholder groups. The numbers of participants completing Rounds 1e3 were 242, 186, and 169, respectively. Seventeen outcomes that met the predefined consensus criteria were considered at two consensus meetings. A final set of 10 core outcomes was agreed: mortality, time from injury to surgery, acute coronary syndrome, hypotension, acute kidney injury, delirium, pneumonia, orthogeriatric input, being out of bed at day 1, and pain. Conclusions: We generated a consensus-based set of core outcomes recommended for use in all perioperative trials evaluating the effects of anaesthesia for hip fracture surgery. An important next step is developing consensus-based consistency on how they should be measured. Clinical trial registration: http://www.comet-initiative.org/studies/details/757.

Ingestion of 3,4-methylene dioxymethamphetamine (MDMA), commonly known as "Ecstasy", can produce toxicity that is characterised by hyperthermia, coagulopathy, rhabdomyolysis and renal failure. We report a fatality associated with MDMA ingestion and briefly review the current literature on MDMA-induced hyperthermia.

IntroductionDifferentiated paediatric epithelial cells can be used to study the role of epithelial cells in asthma. Nasal epithelial cells are easier to obtain and may act as a surrogate for bronchial epithelium in asthma studies. We assessed the suitability of nasal epithelium from asthmatic children to be a surrogate for bronchial epithelium using air-liquid interface cultures.MethodsPaired nasal and bronchial epithelial cells from asthmatic children (n = 9) were differentiated for 28 days under unstimulated and IL-13-stimulated conditions. Morphological and physiological markers were analysed using immunocytochemistry, transepithelial-electrical-resistance, Quantitative Real-time-PCR, ELISA and multiplex cytokine/chemokine analysis.ResultsPhysiologically, nasal epithelial cells from asthmatic children exhibit similar cytokine responses to stimulation with IL-13 compared with paired bronchial epithelial cells. Morphologically however, nasal epithelial cells differed significantly from bronchial epithelial cells from asthmatic patients under unstimulated and IL-13-stimulated conditions. Nasal epithelial cells exhibited lower proliferation/differentiation rates and lower percentages of goblet and ciliated cells when unstimulated, while exhibiting a diminished and varied response to IL-13.ConclusionsWe conclude that morphologically, nasal epithelial cells would not be a suitable surrogate due to a significantly lower rate of proliferation and differentiation of goblet and ciliated cells. Physiologically, nasal epithelial cells respond similarly to exogenous stimulation with IL-13 in cytokine production and could be used as a physiological surrogate in the event that bronchial epithelial cells are not available.
