The long‐term incidence of chronic post‐surgical pain after coronary artery bypass surgery – A prospective observational study

E. Charlton, K. J. Atkins, L. Evered, B. Silbert, more

European Journal of Pain > 28 > 4 > 599 - 607

Background Chronic post‐surgical pain (CPSP) represents a significant issue for many patients following surgery; however, the long‐term incidence and impact have not been well described following cardiac surgery. Our aim was to characterize CPSP at least 5 years following coronary artery bypass grafting (CABG) surgery. Methods This prospective observational study investigated a cohort of patients...

Acute peri‐operative neurocognitive disorders: a narrative review

L. Evered, K. Atkins, B. Silbert, D. A. Scott

Anaesthesia > 77 > S1 > 34 - 42

Peri‐operative neurocognitive disorders are the most common complication experienced by older individuals undergoing anaesthesia and surgery. Peri‐operative neurocognitive disorders, particularly postoperative delirium, result in long‐term poor outcomes including: death; dementia; loss of independence; and poor cognitive and functional outcomes. Recent changes to the nomenclature of these disorders...

Quantitative evaluation of aerosol generation during manual facemask ventilation

A. J. Shrimpton, J. M. Brown, F. K. A. Gregson, T. M. Cook, more

Anaesthesia > 77 > 1 > 22 - 27

Manual facemask ventilation, a core component of elective and emergency airway management, is classified as an aerosol‐generating procedure. This designation is based on one epidemiological study suggesting an association between facemask ventilation and transmission during the SARS‐CoV‐1 outbreak in 2003. There is no direct evidence to indicate whether facemask ventilation is a high‐risk procedure...

Aerosolisation during tracheal intubation and extubation in an operating theatre setting

R. S. Dhillon, W. A. Rowin, R. S. Humphries, K. Kevin, more

Anaesthesia > 76 > 2 > 182 - 188

Aerosol‐generating procedures such as tracheal intubation and extubation pose a potential risk to healthcare workers because of the possibility of airborne transmission of infection. Detailed characterisation of aerosol quantities, particle size and generating activities has been undertaken in a number of simulations but not in actual clinical practice. The aim of this study was to determine whether...

Recommendations for the nomenclature of cognitive change associated with anaesthesia and surgery—2018

L. Evered, B. Silbert, D. S. Knopman, D. A. Scott, more

Canadian Journal of Anesthesia/Journal canadien d'anesthésie > 2018 > 65 > 11 > 1248-1257

Cognitive change affecting patients after anaesthesia and surgery has been recognised for more than 100 yr. Research into cognitive change after anaesthesia and surgery accelerated in the 1980s when multiple studies utilised detailed neuropsychological testing for assessment of cognitive change after cardiac surgery. This body of work consistently documented decline in cognitive function in elderly...

A Self-organising Sensing System for Structural Health Management

N. Hoschke, C. J. Lewis, D. C. Price, D. A. Scott, more

Lecture Notes in Computer Science > Knowledge-Based Intelligent Information and Engineering Systems > Evolutionary and Self-organising Sensors, Actuators and Processing Hardware > 349-357

This paper describes a new approach to structural health monitoring and management (SHM) that aims to diagnose and respond to damage using the self-organization of a complex system of distributed sensors and processing cells. To develop and evaluate the approach, an experimental SHM test-bed system has been developed, with the aim of detecting and characterising the damage from high-velocity impacts...

Fuel Efficiency of Ancient Copper Alloys: Theoretical Melting Thermodynamics of Copper, Tin and Arsenical Copper and Timber Conservation in the Bronze Age Levant*

B. Kaufman, D. A. Scott

Archaeometry > 57 > 6 > 1009 - 1024

The melting of pure or alloyed copper, tin and arsenical copper ingots or recycled objects was a drain on the timber and dung fuel resources of many cultures. This paper suggests formulae grounded in thermodynamic principles in an attempt to estimate the energy requirements necessary to melt copper alloys common to both Old and New World cultures, with the goal of identifying consumption and conservation...

Resonance strengths in the ^17,18 O(p, α) ^14,15 N reactions and background suppression underground

LUNA Collaboration, C. G. Bruno, D. A. Scott, A. Formicola, more

The European Physical Journal A > 2015 > 51 > 8 > 1-12

. We report on measurements of resonance strengths and energies for the $E_{p} = 151$ and 193 keV resonances in the ¹⁸ O(p, $\alpha$ ) ¹⁵ N and ¹⁷ O(p, $\alpha$ ) ¹⁴ N reactions, respectively, obtained during commissioning of a new setup for alpha-particle detection studies at the LUNA underground laboratory. Our values, $\omega\gamma...

A new study of the ²²Ne(p, γ)²³Na reaction deep underground: Feasibility, setup and first observation of the 186 keV resonance

LUNA Collaboration, F. Cavanna, R. Depalo, M. -L. Menzel, more

The European Physical Journal A > 2014 > 50 > 11 > 1-10

The ²²Ne(p,γ)²³Na reaction takes part in the neon-sodium cycle of hydrogen burning. This cycle is active in asymptotic giant branch stars as well as in novae and contributes to the nucleosythesis of neon and sodium isotopes. In order to reduce the uncertainties in the predicted nucleosynthesis yields, new experimental efforts to measure the ²²Ne(p,γ)²³Na cross section directly at the astrophysically...

A network meta‐analysis to compare glycaemic control in patients with type 2 diabetes treated with exenatide once weekly or liraglutide once daily in comparison with insulin glargine, exenatide twice daily or placebo

D. A. Scott, K. S. Boye, L. Timlin, J. F. Clark, more

Diabetes, Obesity and Metabolism > 15 > 3 > 213 - 223

AimsThe glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) exenatide once weekly (ExQW) and liraglutide once daily (QD) are indicated to improve glycaemic control in patients with type 2 diabetes. Although glycaemic control with ExQW versus liraglutide QD 1.8 mg has been directly compared, no studies have compared ExQW with liraglutide QD 1.2 mg or determined the probable relative efficacies of...

2012 6th International Conference on Ultrawideband and Ultrashort Impulse Signals > 24 - 29

2012 6th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS)

Many technical discoveries or inventions begin and end their existence in a university laboratory. Aware of this, both professors and students have asked perceptive questions about how to move their work from the laboratory to the marketplace. This paper provides introductory suggestions to some of the questions most commonly asked at UWBUSIS meetings over the past six years. Both suggestions about...

Preparation and characterisation of isotopically enriched Ta₂O₅ targets for nuclear astrophysics studies

LUNA Collaboration, A. Caciolli, D. A. Scott, A. Leva, more

The European Physical Journal A > 2012 > 48 > 10 > 1-6

The direct measurement of reaction cross-sections at astrophysical energies often requires the use of solid targets of known thickness, isotopic composition, and stoichiometry that are able to withstand high beam currents for extended periods of time. Here, we report on the production and characterisation of isotopically enriched Ta₂O₅ targets for the study of proton-induced reactions at the Laboratory...

. Objective and design: To determine the influence of vitamin C supplementation (500 mg, bd, 14 days) on the circulating concentrations of soluble ICAM-1 (a marker of endothelial activation), neopterin (a marker of monocyte activation), and neutrophil elastase (a marker of neutrophil activation) in smokers and non-smokers in a randomised, double-blind, placebo-controlled trial in a hospital setting...

Tobacco-induced alterations to the Fourier-transform infrared spectrum of serum

J. T. Borden, A. Man, D. A. Scott, K.-Z. Liu

Journal of Molecular Medicine > 2003 > 81 > 12 > 788-794

Infrared (IR) spectroscopy can distinguish differences in the characteristics of diverse molecules by using infrared radiation to probe chemical bonds. Consequently, alterations to the molecular characteristics of tissues and body fluids that help define specific pathological processes and conditions can be identified by IR spectroscopy. This study analyzed the molecular spectrum of cotinine by IR...
