Recent study shows gout actual sources
London - Saba:
A recent study has shown that genetic factors play a greater role in the development of the inflammatory joint condition known as "gout", contrary to what was previously believed to be related to excessive drinking or not eating enough healthy food.
An international team of scientists conducted this study, which was recently published by the British journal Nature Genetics, and searched for genetic data collected from 2.6 million people across 13 different sets of DNA data. This included 120,295 people with 'predominant gout'.
Comparing the genetic codes of people with gout to those without, the team found 377 specific regions of DNA where there were differences specific to the condition – 149 of which had not previously been linked to gout.
While lifestyle and environmental factors certainly still play a role, the findings suggest that genetics play a major role in determining whether someone will develop gout – and the researchers believe there may be more undiscovered genetic links yet to be discovered.
"Gout is a chronic disease with a genetic basis and is not the fault of the person with it – the myth that gout is caused by lifestyle or diet needs to be dispelled," said epidemiologist Tony Meerman of the University of Otago in New Zealand when the study was published last year.
Gout starts when levels of uric acid in the blood rise, leading to the formation of sharp crystals in the joints. When the body's immune system starts attacking these crystals, it causes severe pain and discomfort.
The researchers state that genetic factors are important at every stage of this process. These factors particularly affect the likelihood that the body's immune system will attack the crystals, and the way uric acid is transported throughout the body.
Gout may come and go, but there are treatments available — and the study authors believe that misconceptions can prevent people from getting them. That's a real problem as cases of the condition increase.
"This widespread myth stigmatizes people with gout, making it more likely that some people will suffer in silence and not go to the doctor to get preventative medication that lowers uric acid in the blood and prevents their pain," Meerman said.
In addition to giving us a better understanding of what causes gout, the study gives scientists more options to explore when it comes to treatments, particularly when it comes to managing the body's immune response to uric acid buildup. In fact, existing drugs could be repurposed for this task.
There are some limitations to the study: the majority of the data was from people of European descent, and some registries relied on self-reporting of gout rather than clinical diagnosis. Still, it gives us a much better sense of a health problem that has been plaguing people for centuries.
"We hope that better and more accessible treatments will become available over time with the new targets we have set," Meerman said. "Gout deserves more health spending and greater priority in the health system."

Study: Leprosy Was Latent in Americas Long Before Colonization
Washington - (Saba): A recent scientific study has found that leprosy was latent in the Americas long before European colonization, contrary to the long-held belief that the disease was introduced by European settlers. This suggests that Native Americans had already been dying from the disease for centuries. The primary cause of leprosy is known to be a bacterium called Mycobacterium leprae, and researchers still believe that Europeans introduced it to the Americas. However, a lesser-known cause appears to have been identified at that time. The new study, conducted by an international team of researchers and published in the journal Science, found that another bacterium, Mycobacterium lepromatosis—a less common cause of leprosy—was present in the DNA of ancient human remains from Canada and Argentina dating back at least 1,000 years. "This discovery changes our understanding of the history of leprosy in the Americas," says genomicist Maria Lopopolo of the Pasteur Institute in France. "It shows that a form of the disease was already endemic among indigenous populations long before the arrival of Europeans." Mycobacterium leprae was first detected in a patient in the United States in 2008 and has since also been found in red squirrels (Sciurus vulgaris) in the United Kingdom. Researchers suggest it likely spread from the United States to the United Kingdom in the 19th century. In collaboration with local indigenous communities, regarding the handling of ancestral remains, the researchers analyzed the DNA of a total of 389 ancient human samples and 408 modern human samples. Based on the results, they constructed a genetic family tree for the leprosy bacteria. Although the ancient Canadian and Argentine samples were separated by thousands of kilometers, they were remarkably genetically similar. This suggests a rapid spread of leprosy across The Americas. Based on the timeline compiled from DNA, the various strains of Mycobacterium leprae likely diverged from a common ancestor more than 9,000 years ago. With all these millennia of evolution, the team says there are likely more diverse forms of the bacteria still waiting to be discovered in the Americas. "We are only just beginning to uncover the diversity and global movement of this newly discovered pathogen," says biologist Nicolas Rascovin of the Pasteur Institute. This study allows us to hypothesize the existence of unknown animal reservoirs for this virus. All of this adds a valuable dimension to our understanding of the history of the Americas and of leprosy. It provides researchers with crucial data regarding the evolution and diversity of the disease. Infectious diseases have played a significant role in the history of North, South, and Central America, with the arrival of Europeans bringing with them a range of new pathogens for which indigenous communities were biologically unprepared. We now know that the leprosy aspect is more complex than previously thought. Around 200,000 new cases of the disease are reported globally each year, even though it is now treatable and curable with modern medicines. 'This study clearly demonstrates how ancient and modern DNA can rewrite the history of human pathogens and help us better understand the epidemiology of contemporary infectious diseases,' says Rascovan.

"Rosatom" Plans to Launch New-Generation Fast Neutron Reactor in 2030
Moscow - (Saba): Alexei Likhachev, CEO of the Russian state-owned nuclear corporation Rosatom, announced on Tuesday that the company plans to launch a unique, new, fourth-generation fast-neutron reactor in 2030. Likhachev said, according to Sputnik, "A unique project is the construction of a fourth-generation nuclear power plant in Seversk (Tomsk Oblast)... In 2030, we will launch a 300-megawatt fast nuclear reactor, the world's first fourth-generation power plant." Earlier, Likhachev said that Rosatom maintains Russia's "nuclear shield" at an appropriate level so that no one would consider using weapons against Russia. Likhachev indicated that the company is ready to cooperate with the United States on uranium supplies unless a different decision is made. "We will be present on the European market in one way or another, and we will cooperate with the United States in uranium supplies unless another decision is made," Likhachev said.
