A blow to the head impairs the autoregulation of brain blood flow: Neural consequences

Written by

Professor Akos Koller investigates the impact of traumatic brain injuries on cerebral blood flow and the ensuing consequences on brain function

Billions of cells make up the human brain. To keep this super-computer functioning, a carefully autoregulated blood supply provides oxygen and nutrients and removes waste products from the brain cells. In addition, cerebral circulation is involved in the regulation of the pressure inside the cranium. But what happens if this autoregulatory process is disrupted? Building on years of research into […]

A paradigm shift for fluid management in surgery

Written by

Advances in modern surgery have been dependent upon advances in anaesthetic management. However, anaesthesia can have detrimental effects, as it is usually associated with reduced blood pressure, cardiac output and oxygen delivery. To counteract these changes, large quantities of intravenous fluids have been administered both during and often for many hours post-surgery. This was in an attempt to maintain blood […]

Magnitude of uncontrolled hypertension, and associated factors, amongst adult hypertensive patients in public hospitals of Central Zone, Tigray, Ethiopia, 2018

Written by

Uncontrolled hypertension For the general hypertensive population, uncontrolled hypertension (high blood pressure) is if the systolic blood pressure (SBP) is ≥140 mm Hg and/or diastolic blood pressure (DBP) is ≥90mm Hg. For inpatients with established diabetes mellitus or chronic kidney disease – it’s when SBP is ≥130 mm Hg and/or DBP is ≥80mm Hg. Blood pressure results are based on […]

High pressure talk with Professor Rhian Touyz

Written by

At the Institute of Cardiovascular and Medical Science (ICAMS) at the University of Glasgow, world-renowned researchers are dedicated to discovering mechanisms of cardiovascular disease (CVD) in their quest to advance new treatments and to develop improved prevention, management and diagnostic strategies. Professor Rhian Touyz takes an innovative new approach to preventing CVD by conducting extensive research into other intricately linked […]
