Genetic Factors: The Primary Cause of Gout - Jordan News
Gout is often linked to excessive alcohol consumption or an unhealthy diet, but research suggests that genetic factors play a much larger role in the development of this inflammatory joint condition than previously thought. اضافة اعلان
A recent study conducted by an international team of scientists analyzed genetic data from 2.6 million people across 13 different DNA datasets , including 120,295 individuals with prevalent gout .
By comparing the genetic codes of those with and without gout, researchers identified 377 specific regions in the DNA linked to the condition, 149 of which had never been previously associated with gout .
While environmental factors and lifestyle choices still play a role, the findings indicate that genetics is the primary determinant of whether a person develops gout. Scientists believe that there may still be undiscovered genetic links contributing to the disease. Gout: A Genetic Condition, Not a Lifestyle Mistake
Tony Merriman, an epidemiologist from the University of Otago, New Zealand , stated, "Gout is a chronic disease with a genetic basis—it's not the patient's fault. The myth that gout is simply caused by lifestyle or diet needs to be dispelled."
Gout occurs when high levels of uric acid accumulate in the blood, leading to the formation of sharp crystals in the joints . When the immune system attacks these crystals, severe pain and inflammation follow.
According to Nature Genetics , genetics influence every stage of this process, particularly how the immune system responds to these crystals and how uric acid is transported in the body. The Impact of Misconceptions on Treatment
Gout can be episodic , but treatments are available . However, misconceptions about the disease discourage many patients from seeking medical help.
Merriman explained, "The widespread myth that gout is self-inflicted leads to stigma, making many sufferers hesitate to see a doctor for preventive medication that lowers uric acid levels and alleviates their pain."
Beyond improving understanding of gout's causes, the study also presents new treatment possibilities , particularly in managing the immune system's response to uric acid accumulation. Existing medications could potentially be repurposed for this purpose. Study Limitations
Most of the study data came from European populations , and some records were based on self-reported gout cases rather than clinical diagnoses. However, the findings offer a deeper insight into a health issue that has affected people for centuries.
Merriman added, "We hope that over time, better and more accessible treatments will emerge, using the new genetic targets we've identified. Gout deserves greater healthcare resources and priority in medical systems." Understanding Gout: Symptoms and Causes What is Gout?
Gout is a complex form of arthritis that can affect anyone. It is characterized by sudden, intense pain, swelling, redness, and tenderness in one or more joints— most commonly the big toe .
A gout attack can occur suddenly , often waking a person up in the middle of the night with a burning sensation in the affected joint, which becomes hot, swollen, and extremely painful to touch . Symptoms of Gout
Gout symptoms often appear suddenly , typically at night, and include: Severe joint pain – Commonly in the big toe , but also in the ankles, knees, elbows, wrists, and fingers. Pain peaks within 4 to 12 hours .
– Commonly in the , but also in the ankles, knees, elbows, wrists, and fingers. Pain . Lingering discomfort – Even after the worst pain subsides, discomfort may persist in the joints for days to weeks .
– Even after the worst pain subsides, discomfort may persist in the joints for . Inflammation and redness – Affected joints become swollen, warm, tender, and reddish in color .
– Affected joints become . Limited range of motion – As gout worsens, moving the affected joints may become difficult. What Causes Gout?
According to the Mayo Clinic , gout occurs when uric acid crystals accumulate in the joints, causing inflammation and intense pain .
Uric acid forms when the body breaks down purines , substances found naturally in the body and certain foods . Foods high in purines include: Red meat and organ meats (like liver)
(like liver) Certain seafood (anchovies, sardines, mussels, scallops, trout, and tuna)
(anchovies, sardines, mussels, scallops, trout, and tuna) Alcoholic beverages , especially beer
, especially Sugary drinks with fructose
Normally, uric acid dissolves in the blood and is excreted through the kidneys in urine. However, if the body produces too much uric acid or the kidneys fail to eliminate enough , uric acid accumulates, forming needle-like crystals in the joints, leading to pain, swelling, and inflammation .
While diet and lifestyle contribute to gout, this study underscores the significant role of genetics , shifting the focus from personal habits to biological predisposition.

Simple Habits That Trick Your Body into Staying Young - Jordan News
Simple Habits That Trick Your Body into Staying Young A recent study has found that combining three simple lifestyle factors can significantly slow down the biological aging process in people over the age of 70. اضافة اعلان The promising findings come from the renowned DO-HEALTH study, led by a research team at the University of Zurich under Professor Heike Bischoff-Ferrari. The three-year study involved 777 participants and relied on cutting-edge technology known as epigenetic clocks—developed by scientist Steve Horvath—which track subtle chemical changes in DNA to accurately measure a person's biological age, rather than their chronological age. The Powerful Trio: Omega-3, Vitamin D, and Strength Training The study revealed that the combination of omega-3 supplements, vitamin D, and regular strength exercises significantly slowed down biological aging in people in their seventies. Taking omega-3 supplements alone was shown to reduce biological age by up to four months, regardless of gender or body mass index. However, the most striking results appeared when participants combined all three elements: omega-3, vitamin D, and at-home strength training three times a week. This synergy created a compounding effect that slowed aging much more effectively than any of the components alone. Professor Bischoff-Ferrari explains: "These three elements act through different but complementary mechanisms—omega-3 supports cellular health, vitamin D boosts vital functions, and strength training promotes tissue regeneration. Together, they deliver a much more powerful anti-aging impact." The study adds to earlier findings that this combination also reduces the risk of cancer, frailty, and infections in older adults. However, this is the first time such a direct impact on the aging process itself has been demonstrated. Promising but Early Despite the encouraging results, researchers caution that the study is still in its early stages. It was conducted only on participants in Switzerland, and epigenetic clock technologies are still evolving. Nevertheless, the research team is now planning to expand the study across other European countries, in collaboration with an international alliance focused on extending healthy lifespan. In the end, it seems the key to slowing down time may not lie in a complicated drug or high-tech procedure—but in daily habits that anyone can adopt. Professor Bischoff-Ferrari concludes: "Aging is a complex process, but this study shows that we already have some simple tools to positively influence it." Source: SciTechDaily

Macron welcomes France's right to assisted dying bill vote
France's lower house on Tuesday approved a right-to-die bill in the first reading, the initial step in a lengthy process that could grant patients medical assistance to end their lives in clearly defined circumstances. "The National Assembly's vote on legislation concerning the development of palliative care and assisted dying is an important step," President Emmanuel Macron said on X after 305 lawmakers approved the legislation and 199 voted against. "With respect for sensitivities, doubts and hopes, the path of fraternity that I hoped for is gradually opening up." Macron has insisted that any authorisation to choose death should be limited to people with incurable illnesses and intense physical or psychological pain. The National Assembly vote was an initial stage for the draft law, which will now go between the lower house and the Senate for modifications acceptable to both houses. Some conservative groups oppose the law and Macron has said he could put the deeply divisive topic to a vote by referendum. If approved, France would join a small group of European countries that give the right to aid in dying, including Germany, Spain, Austria and Switzerland. Until now, French patients wishing to end their lives have had to travel abroad, including to neighbouring Belgium. A separate bill, submitted at the same time and concerned with end-of-life medical assistance including palliative care, passed on Tuesday without opposition. All parties in parliament have allowed their lawmakers a free vote on the issue. Leftist and centrist parties were expected to vote in favour of the right-to-die bill, with conservatives and far-right deputies seen broadly hostile. The bill is widely referred to as focusing on "end of life" or "aid in dying" in the French debate, rather than "assisted suicide" or "euthanasia". 'Expressed such a wish' The bill brought by Macron ally Olivier Falorni would allow medical staff to help "a person gain access to a lethal substance when they have expressed such a wish". The patient would use the substance without aid or have it administered by a medically qualified person "if they are in no condition physically to do so themselves". Health Minister Catherine Vautrin said at the weekend that the "French model" of assisted dying would be "strict and closely supervised". Macron said last year that France needed legislation because "there are situations you cannot humanely accept". The goal was "to reconcile the autonomy of the individual with the solidarity of the nation", he said. The bill faces stiff opposition from religious leaders in a country with a longstanding Catholic tradition, as well as many health workers. Prime Minister Francois Bayrou, a devout Catholic, said Tuesday that he would abstain if he were a deputy because of lingering "questions". The draft law would allow assisted dying only in an "advanced" stage of illness, which it defines as "entering an irreversible process characterised by a worsening health condition of the sick person that affects the quality of their lives." Current French legislation allows passive euthanasia, such as withholding artificial life support, and since 2016 doctors have also been authorised to induce "deep and continuous sedation" for terminally ill patients in pain. But active euthanasia, where doctors administer lethal doses of drugs to patients, remains illegal. Vautrin said she hopes that the Senate will begin examining the issue this year and submit its suggested changes back to the National Assembly in early 2026. "I want this bill to get a final vote by 2027 which is still possible," said the minister.

Hamas issues new statement on recent European stances
The Palestinian movement Hamas issued a press statement welcoming the recent positions taken by several European countries regarding the humanitarian crisis in Gaza, while urging world leaders to take urgent steps to end the ongoing "Israeli" assault and lift the blockade on the besieged coastal territory. In the statement released on Thursday, Hamas praised the "humanitarian and courageous" stance of Spain, Norway, Iceland, Ireland, Luxembourg, Malta, and Slovenia. The countries issued a joint declaration calling for an end to the war on Gaza, the lifting of the blockade, and condemned both the "Israeli" escalation and settler violence in the occupied West Bank. 'These moral and responsible positions represent a cry of conscience in the face of the occupation's crimes,' the statement read, adding that they 'expose the falsehoods and lies of the enemy's narrative that seeks to justify genocide and starvation.' Hamas also expressed appreciation for French President Emmanuel Macron's recent remarks, in which he called for an immediate ceasefire, an end to the blockade on Gaza, and condemned "Israel's" targeting of Palestinian civilians. The group called on international leaders to 'raise their voices loudly against the Zionist occupation and its brutal massacres,' and to pressure Israel into ending the war and complying with international law. Hamas concluded its message by urging Arab states to adopt a unified stance to stop what it called a 'war of extermination' against the people of Gaza, and to ensure the immediate and unimpeded entry of humanitarian and medical aid. The Gaza Strip has faced months of bombardment, with mounting casualties and severe shortages of food, water, and medicine. Gaza's health authorities say tens of thousands have been killed or wounded, many of them women and children. The United Nations has warned of imminent famine and a total collapse of the healthcare system if aid access is not urgently restored.
