Preoperative Internal Medicine Consultation for Elective Intermediate-to-high Risk Noncardiac Surgery in Ontario
This dissertation uses population-based administrative healthcare data to evaluate the outcomes, processes-of-care and practice variation associated with preoperative medical consultation in Ontario, Canada. First, a multicentre cross-sectional study was conducted to develop a novel algorithm for …

Preoperative testing and medical therapy intervention to improve perioperative outcomes in noncardiac surgical patients.
Introduction: Cardiovascular disease is the leading cause of death worldwide and a growing concern in low-and-middle income countries, including those in Africa. Patients with cardiovascular disease often have poorly managed chronic conditions in the African setting, which impacts their outcome …

Study of epidemiology, management and outcome of acute kidney injury post noncardiac surgery over 12 months at Groote Schuur Hospital, Cape Town
INTRODUCTION : Acute kidney injury (AKI) is a disorder that is defined by rising serum creatinine and reduced urine output. It occurs in approximately 1-7% of hospitalized patients and is a major predictor of morbidity and mortality. It increases the costs and duration of hospital stay. AKI has …

A systematic review of outcomes associated with withholding or continuing angiotensinconverting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARB) prior to noncardiac surgery
Introduction The global rate of major noncardiac surgical procedures is increasing annually, and of those patients presenting for surgery increasing numbers are taking either an angiotensin-converting enzyme inhibitor (ACE-I) or an angiotensin receptor blocker(ARB). The current recommendations …

The association between preoperative anaemia and surgical mortality and morbidity in South African surgical patients
… and in-hospital mortality in South African adult noncardiac, non-obstetric patients. The secondary objectives were to describe the association between preoperative anaemia and i) critical care admission, and ii) length of hospital stay, and to describe the prevalence of preoperative anaemia in …

Cardiac Vasoactive Peptides in Hypertrophic Cardiomyopathy of Cats
… HCM than normal cats, it is probably due to noncardiac sources. The lack of detectable vasopressin expression suggests that vasopressin is not produced in significant amounts in feline cardiac tissue, contrasting with previous studies performed in rats.

Parametric heart modelling and in silico closed-loop validation of implantable devices
… far-field extracellular potentials together with noncardiac signals-electrograms (EGMs). All modern implantable devices incorporate blanking periods and refractory periods to discriminate these signals and identify the intrinsic local depolarization. To the best of our knowledge, no existing work …
