New research from the Department of Physiology, Anatomy and Genetics has shown that in type 2 diabetes an overload of lipids reduces the heart’s ability to generate energy during a heart attack, decreasing chances of recovery.

In patients with type 2 diabetes, the heart becomes starved of energy, leading to decreased recovery in the event of a heart attack. Diabetes is associated with high blood glucose and high blood lipids. Diabetes research tends to focus on the effects of high glucose, but changes in glucose concentrations do not explain why there is an energy deficit in the heart in type 2 diabetes.

It is known that the heart becomes laden with lipids in diabetes. Yet, there have been very few studies investigating the consequences of these high levels of lipids in the heart. Neither the specific lipids causing the metabolic upheaval that leads to energy starvation in the heart, nor the signalling pathways on which they are exerting these effects, have been identified.

New study finds that politicians typically enjoy longer lives than general populations

New data show politicians have a considerable survival advantage over general populations, based on information from 11 countries and over 57,500 politicians. In some countries this survival advantage is at the highest level for 150 years, and life expectancy at age 45 was found to be around seven years higher for politicians compared to general populations in certain countries.

Five ways the pandemic has affected routine medical care

Since the beginning of the pandemic, COVID has infected at least a third of the UK population and is estimated to have factored in the deaths of almost 200,000 people in the UK. But critically, COVID has also had a devastating impact on our healthcare systems. While this was expected, new evidence is beginning to reveal the scope of the issue – in particular the effects for people living with long-term health conditions.
