COVID-19 viremia linked to deadly clots in new study

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.

Common Sugar Alcohol in Diet May Boost Stroke Risk, Lab Finds

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.

Two genetic twists behind rare vaccine-induced clots, study finds

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.

Hidden signs of deadly lung clots: a cardiologist explains under-diagnosed pulmonary embolism

Hidden signs of deadly lung clots: a cardiologist explains under-diagnosed pulmonary embolism

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.

Light Color's Potential to Prevent Heart Attacks and Strokes

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.

Silent Symptom May Indicate Blood Clots

Silent Symptom May Indicate Blood Clots

Blood clots can cause serious health issues like strokes and heart attacks, with a key silent symptom being sudden, intense shortness of breath, especially in cases of pulmonary embolism. Recognizing this symptom early is crucial for prompt treatment and can be life-saving, as it often presents suddenly and worsens with exertion or deep breaths.
