A Goddard, Kansas mother survived a spider bite at Cheney Lake that led to life-threatening blood clots and was believed to cause end-stage liver failure; after multiple surgeries, infections, and weeks in intensive care, she recovered enough to leave the hospital and is awaiting a liver transplant, with doctors stating a dire prognosis earlier in her care.
Basketball Hall of Famer Chris Bosh says he nearly died from a pulmonary embolism in January, requiring a hospital stay and daily medication, and notes that he’ll have to manage the condition for life. He previously battled blood clots in 2015 and 2016 that ended his NBA career, and is now pursuing media work while staying vigilant about his health.
A study of 93 hospitalized COVID-19 patients shows that the virus in the bloodstream (viremia) is associated with higher clotting and death, likely via soluble thrombomodulin shed from damaged blood vessels. This mechanism could explain strokes, heart attacks, and pulmonary embolisms in non-ICU patients and suggests earlier anticoagulation might help, though causality isn’t proven and future research is needed to confirm applicability beyond COVID-19 and to account for vaccination-derived antibodies.
Researchers traced vaccine-induced immune thrombocytopenia and thrombosis (VITT) to antibodies against PF4 caused by molecular mimicry with an adenovirus vector protein, enabling vaccine designers to modify the vector to remove the offending protein while maintaining protection.
CU Boulder researchers found that erythritol, a sugar alcohol widely used in protein bars and zero-sugar drinks, altered brain blood vessel cells in vitro: less nitric oxide, more endothelin-1, and about 75% higher reactive oxygen species. When thrombin was introduced, erythritol also blunted tissue plasminogen activator (t-PA), reducing the body's ability to dissolve clots. The study echoes a 2023 epidemiological link between higher blood erythritol and stroke/heart attack risk, but authors caution that causality isn’t proven and endogenous production of erythritol may confound results, so continuing evaluation of non-nutrient sweeteners is prudent.
A global study of 100 VITT patients shows that the rare clotting after adenovirus-based vaccines arises when antibodies that initially target an adenoviral protein mutate once on a common immune gene background, enabling strong binding to platelet factor 4 and clot formation. This two-event trigger—inheritance of a specific immune gene variant and a rare mutation in antibody-producing cells after exposure—helps explain VITT’s rarity and could guide safer vaccine designs while preserving the value of adenovirus-based vaccines.
Former Heat star Chris Bosh says a rapid, frightening medical emergency left him on the ground and waking up covered in blood as he prepared for a date night; he emphasizes being lucky to be alive and notes the experience has reshaped his outlook on life, while recounting his past retirement due to blood clots.
Cardiologists warn that pulmonary embolism, often beginning as a leg DVT, can present with chest pain, breathlessness, a racing heart, or blue-tinged lips/nails and is frequently missed, especially in milder cases. Cancer markedly increases clot risk, which may explain Catherine O’Hara’s death from an embolism, and prolonged immobility (like long flights) also raises risk. Prevention includes staying mobile and wearing compression socks on long journeys; treatment usually involves anticoagulants and, in severe cases, surgery. Early recognition is crucial since large emboli can be fatal within hours, though smaller clots can be dangerous if untreated.
Colorado coach Deion Sanders is scheduled for a four-hour surgery to address blood clots in his foot but plans to return to coaching immediately afterward, emphasizing his commitment to practice and his positive outlook.
Colorado coach Deion Sanders is experiencing significant health issues, including pain and potential blood clots, while his team struggles on the field. Sanders has a history of blood clots leading to toe amputations and is also recovering from bladder cancer. Despite his health concerns, he downplays the focus on his condition.
Deion Sanders revealed he has more blood clots in his leg after Colorado's loss to TCU, and is experiencing significant pain; he has a history of blood clot issues and recent health treatments, including cancer recovery and foot surgeries.
Deion Sanders revealed he suspects he has more blood clots in his leg, which caused him significant pain and affected his health during Colorado's football game, adding to his ongoing health struggles including previous treatments for bladder cancer and blood clot issues.
A Philadelphia hospital has identified a new risk factor for dangerous lung and heart blood clots called CTEPH, particularly in women with pelvic vein obstructions or those undergoing estrogen treatments for fibroids. Early detection and surgical treatment have a high success rate, as exemplified by a patient's recovery.
Research suggests that exposure to red light may reduce blood clot formation by influencing platelet activity and immune responses through the eye-brain pathway, potentially lowering the risk of heart attacks and strokes. Human observational data hints that blue light filtering lenses could also decrease clot risk, especially in cancer patients, but further clinical trials are needed to confirm these findings and explore light-based prevention strategies.
Deion Sanders lost two toes in 2021 due to blood clots that caused severe circulation problems following foot surgery, leading to multiple surgeries and nearly amputation of his leg, revealing serious health challenges he faced during his coaching career.
