Say NO to energy drinks to maintain your blood pressure!

Are energy drinks your workout companion? If yes, ditch them because energy drinks might increase your risk of cardiac problems, says a new study. The researchers found that healthy young adults who don’t consume caffeine regularly experienced a greater rise in resting blood pressure after consumption of a commercially available energy drink – compared to a placebo drink.

How was the study conducted?
In the study, researchers alternately gave a can of a commercially available energy drink or a placebo drink to 25 healthy young adults, age 19 to 40 and assessed changes in heart rate and blood pressure.Blood pressure and heart rate were recorded before and 30 minutes after energy drink/placebo drink consumption and were also compared between caffeine-naive participants (those consuming less than 160 mg of caffeine per day) and regular caffeine users.

What were the study results?
Participants experienced a marked rise in blood pressure after consuming the energy drink as compared to the placebo. The effect was most dramatic in people who did not typically consume much caffeine, researchers found. Overall, the blood pressure increase was more than doubled in caffeine naive adults after consuming the energy drink versus placebo, they found.

Svatikova concluded that consumers should use caution when using energy drinks because they may increase the risk of cardiovascular problems, even among young people.

Kidney failure could become a global pandemic by 2030!

There’s always a flipside to development as problems that usually belonged to developed nations start haunting developing ones. One of them is kidney failure and a new study suggests that by 2030 around 5 million people will need either a kidney transplant or dialysis. This is due to a rise in kidney-related issues in developing nations of Asia and Africa, according to a study by the George Institute for Global Health published in the Lancet.  ‘However, the number of people without access to RRT will remain substantial,’ the study titled ‘Worldwide access to treatment for end-stage kidney disease: a systematic review’ said.  

The largest absolute growth in the number of people receiving RRT is projected to rise from 0.968 million people in 2010 to 2.162 million by 2030 in Asia. The review said about 2.618 million people received this life-sustaining treatment worldwide in 2010.  However, it noted ‘at best, only half or less of all people needing RRT worldwide had access to it in 2010, meaning at least 2.284 million people might have died prematurely because they did not have access to the treatment in 2010’.

Most of this burden of preventable deaths fell on low income and middle income countries like India, China, Indonesia, Pakistan and Nigeria. This data show a pressing need to develop low-cost RRT alternatives to reduce disparities in access to the treatment, and the importance of development, implementation, and assessment of cost-effective end-stage kidney disease prevention strategies. 

‘The sad reality is that most of these deaths are preventable and the biggest burden lies in low to middle income countries where there are instances of less than a quarter of patients receiving treatment for kidney failure,’ said Vlado Perkovic of the George Institute and lead author of the study. He said the way forward is to ‘radically overhaul’ dialysis technology to lower costs.

‘Dialysis has been around for half a century, yet the technology hasn’t evolved substantively, remaining hugely expensive despite its simplicity. Computers have shrunk from the size of buildings to that of a watch in this time; that’s the kind of radical overhaul needed,’ added Perkovic. As a result of this research, a worldwide competition is being launched to design the world’s first affordable dialysis machine, attracting a prize of $100,000.
