Breathing Could Bring Microplastics Into the Human Brain, Study Shows
Publicado em 16 de setembro de 2024
MONDAY, Sept. 16, 2024 (HealthDay News) -- For the first time, scientists have detected microscopic microplastics lodged in the human brain.
Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb.
The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.
Although microplastics have already been found in human lungs, intestines, [...]

Wildfires caused major CO2 emissions last year: annual study
Publicado em 13 agosto 2024Paris (AFP) – Wildfires made more frequent and intense by climate change released significant quantities of CO2 into the air in 2023-2024, said a first-of-its-kind annual study published Wednesday. Fires in natural areas caused 8.6 billion tonnes of CO2 emissions worldwide between March 2023 and February 2024 -- 16 percent above average. Only a relatively calm fires season in the African savannah prevented the 2023-2024 season from breaking a fresh record for CO2 emissions at the [...]ver notícia -
PTSD Triples Odds for Teeth Grinding, Study Finds
Publicado em 16 maio 2024THURSDAY, May 16, 2024 (HealthDay News) -- People with post-traumatic stress disorder (PTSD) face more than triple the odds of bruxism, otherwise known as teeth grinding, a new study finds. The small study of 76 Brazilian adults (38 diagnosed with PTSD and 38 without the condition) found much higher incidence of daytime teeth grinding. “Our study showed that PTSD can be manifested orally, in bruxism and a higher level of pain after a clinical dental examination. This requires joint [...]ver notícia -
Too Many 'Bad' Carbs, Too Much Meat: Diet Choices Are Driving Rise in Type 2 Diabetes
Publicado em 18 abril 2023TUESDAY, April 18, 2023 (HealthDay News) -- Most cases of type 2 diabetes can be linked to making poor food choices, a new study finds. Researchers from Tufts University in Boston linked poor diet to 14 million cases of type 2 diabetes — about 70% of new diagnoses globally — in 2018. The biggest impact came from insufficient intake of whole grains, too much refined rice and wheat, and overconsumption of processed meat.

Even Mild COVID Is Hard on the Brain
Publicado emEven mild cases of COVID-19 can affect the function and structure of the brain, early research suggests. Dr Clarissa Yasuda “Our results suggest a severe pattern of changes in how the brain communicates as well as its structure, mainly in people with anxiety and depression with long COVID syndrome, which affects so many people,” study investigator Clarissa Yasuda, MD, PhD, from University of Campinas, São Paulo, Brazil, said in a news release. “The magnitude of [...]ver notícia
