Saúde do timo pode prever longevidade e resultados de câncer

Uma nova pesquisa da Mass General Brigham mostra que o timo, um pequeno órgão antes considerado irrelevante em adultos, influencia fortemente a expectativa de vida e o risco de doenças. Usando IA em tomografias computadorizadas, cientistas associaram uma melhor saúde tímica a riscos menores de morte e progressão do câncer.

Os pesquisadores examinaram tomografias computadorizadas de mais de 25.000 adultos em um estudo de rastreamento de câncer de pulmão e de mais de 2.500 participantes do Estudo de Framingham. Eles desenvolveram um escore de saúde tímica baseado no tamanho, na estrutura e na composição do órgão. Adultos com pontuações mais altas apresentaram um risco cerca de 50 por cento menor de morte por qualquer causa, um risco 63 por cento menor de morte cardiovascular e um risco 36 por cento menor de câncer de pulmão.

Study of young lung cancer patients finds unexpectedly high diet-quality scores; researchers probe possible pesticide exposure

Preliminary research from USC Norris Comprehensive Cancer Center, presented at the American Association for Cancer Research (AACR) annual meeting, found that non-smokers diagnosed with lung cancer before age 50 reported eating more fruits, vegetables and whole grains—and had higher overall Healthy Eating Index scores—than the U.S. population average. The researchers emphasized that the results do not prove diet causes lung cancer and said a possible explanation could involve environmental exposures such as pesticides, a hypothesis that requires direct testing.

Severe COVID or flu may raise lung cancer risk years later

New research indicates that severe cases of COVID-19 or influenza can alter lung immune cells, potentially increasing cancer risk months or years afterward. The study, conducted by scientists at the University of Virginia, highlights the role of chronic inflammation in this process and emphasizes vaccination as a preventive measure. Findings suggest closer monitoring for affected patients to enable early detection.

Genes account for half of human lifespan variation, study shows

13 de abril de 2026 Reportado por IA

Researchers at Israel's Weizmann Institute of Science have determined that genetics explain about 50% of differences in human lifespan, far more than previously estimated. The finding, published in the journal Science, challenges earlier views that placed genetic influence at 20-25% or less. By analyzing twin data and filtering out external death causes, the team uncovered this stronger hereditary role.
