Fat deposits near heart can help predict risk posed by kidney disease

Fat deposits around the heart – which can be spotted through simple CT scans – can help predict the risk of death in patients with chronic kidney disease, research shows.
The study, published in the journal Nephrology Dialysis Transplantation, was conducted by scientists from Canada, Venezuela, Italy and the US, Xinhua reported. 
‘We wanted to know if this type of heart fat is related to poor outcomes for patients with chronic kidney disease, and it was a very clear marker of risk,’ said Paolo Raggi, a researcher from the University of Alberta in Edmonton, Canada. 
‘The greater the amount of fat around the heart, the greater the mortality rates were in patients.’
After examining CT scans of 109 American patients with chronic kidney disease from a randomised, clinical trial, the researchers found that for every 10 cubic cm increase in heart fat, the risk of death rose six percent.
The findings also showed that high levels of calcium or plaque in the arteries and high cholesterol levels were strong predictors of large volumes of heart fat.
Previous research showed a link between this heart fat and plaque buildup in the heart arteries, according to the researchers.

Surgeon live-streams operation through Google Glass

Two operations led by Dr J S Rajkumar of Lifeline Hospitals were live-streamed to a group of medical students on Tuesday. Using Google Glass, the doctors were able to show the complete procedure of upper gastro-intestinal laparoscopy and a hernia repair surgery. This is the first time, the gadget was used to live-stream a surgery in India.
‘It felt like I was glancing at my rearview mirror while driving. I was focusing on the surgeries and talking to my students at the same time. At one point, I stopped feeling it was an external device,’ Dr J S Rajkumar told TOI.
What is Google Glass?
Google Glass is a wearable computer for your eyes, and it looks similar to normal eyeglasses. Once worn, the glass follows natural language commands to perform its many functions.
Dr Rajkumar also said that the tool can be great for both conducting surgeries, and educating young doctors about its methods. Doctors could use the tool to view medical information like X-rays, MRI images, etc. while conducting the surgery.
Priced at $1,500, the glass could prove to be too expensive a gadget for a lot of surgeons and has its share of detractors too. ‘I use a camera attached to my head which is live-streamed to audiences in different parts of the world. So what makes this gadget special? We’ll have to wait till it hits the market.’ Dr R Ravi Kumar, director, institute of cardiovascular disease, robotic surgery centre at Chettinad Health City told TOI
Previously, Dr Vikas Agarwal, a leading ENT surgeon had live-streamed a surgery to treat obstructive sleep apnoea, which was seen by over 2000 doctors around the world.
