Heart News Better preservation method for donated hearts Longer preservation time means more people could receive organs for transplant Aspecially designed heart box has shown to preserve donated hearts for longer than standard methods, according to a Swedish study published in Nature Communications, raising hopes it could make heart transplants easier and safer. The box supplies the organs with an oxygenated, blood-mixed solution that preserves them for five and a half hours, while standard preservation techniques are limited to four hours. Increased preservation time would allow organs to be transported farther away to reach patients in need of a transplant. Researchers are hoping they can use the box to preserve hearts for as long as 12 hours and have already succeeded in preserving pig hearts for 24 hours. “Based on the results we have produced so far, we cannot claim with certainty that we are able to preserve a heart for 12 hours; however, our study shows that the new method enables longer preservation than today. If we, in our continued research, can establish that this is possible, it would mean entirely new opportunities for transplants. It would, for example, be possible to fly hearts between countries, which we currently cannot,� said Dr Johan Nilsson, study author and cardiothoracic surgeon at �k�ne �niversity Hospital in �weden, in a press release. “The plan now is that we will shortly test the new method with a group of 33 patients. In addition to the six patients who participated in the study, we have also used the method in an additional nine transplants. And it still looks promising,� he said. Cholesterol trends in Asia have worsened Study offers positive news for the West, but negative data in Asia means policies and dietary practices need to change Average levels of cholesterol in the blood are going down in Western countries while increasing in low-and-middle-income nations, especially in Asia, according to the largest cholesterol study ever conducted. Though cholesterol is an important cell constituent, high levels of the non-HD� cholesterol (�bad�) type in the blood can lead to heart attacks and strokes by blocking blood supply. �nhealthy eating habits are one reason behind high levels of non-HD� cholesterol, such as diets rich in artificial trans fats (common in fried foods) and, to a lesser extent, saturated fats, which can be found in a variety of foods like dairy products, red meat, and many baked goods. Analysing data from more than 100 million people across 200 countries, the study showed that, between 1980 and 2018, levels of non-HD� cholesterol fell in northwestern Europe, North America, and Australasia but surged in East Asia and Southeast Asia, especially China. ��or the first time, the highest levels of non-HD� cholesterol are outside of the Western world. This suggests we now need to set into place throughout the world pricing and regulatory policies that shift diets from saturated to non-saturated fats, and to prepare health systems to treat those in need with effective medicines. This will help save millions of deaths from high non-HD� cholesterol in these regions,� Dr Ma�id Ezzati, lead author of the research and professor in the �chool of �ublic Health at Imperial College �ondon, said in a press release. 26 JULY 2020 GlobalHealthAndTravel.com
