A study conducted in Brazil points to long-term functional abnormalities in their lungs two years after hospital discharge in most severe COVID-19 patients who had required intubation, and a return of pulmonary lesions after 24 months in some people who appeared to have fully recovered on being discharged. The study involved 237 patients admitted to Hospital das Clínicas, a hospital complex run by the University of São Paulo's Medical School (FM-USP), between March and [...]

Already at the beginning of the COVID-19 pandemic, a group of Brazilian researchers pioneered in showing why SARS-CoV-2 infection tends to be more severe in diabetic patients. Now, the same team based at the Institute of Biology of the State University of Campinas (IB-UNICAMP) has discovered one of the reasons why obese people who do not have diabetes or even insulin resistance also have an increased risk of developing the severe form of the disease. “New experiments show that the [...]

The concept of “One Health” – which emphasizes the relationship between human, animal, plant and environmental health – has been gaining ground in scientific discussions in recent years. Brazilian and North American researchers developing research using this approach presented their work on Tuesday (April 9th), in Chicago (United States), during FAPESP Week Illinois. One of the panelists was Eduardo Esteban Bustamante, a professor at the University of Illinois in [...]

The chikungunya virus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes and responsible for more than 900 deaths in Brazil since it arrived around ten years ago, is capable of spreading through the blood, reaching multiple organs and crossing the blood-brain barrier, which protects the central nervous system. The mechanisms of action observed for the first time in fatal cases by a group of Brazilian, American and British researchers are reported in an article published in Cell [...]

Offspring of rats that consume excessive amounts of fructose develop disturbances in the autonomic nervous, cardiovascular, and metabolic systems at an early age, increasing the risk of chronic diseases such as diabetes and obesity in adulthood, according to a study conducted by Brazilian scientists. The study is published in the International Journal of Obesity. The findings confirm information in the scientific literature regarding the appearance of metabolic disorders such as high levels [...]

Motivated by a desire to control their weight or live a healthier life, large numbers of people display behavior, thoughts or feelings about food and the body referred to by specialists as “dysfunctional dietary behavior” or “disordered eating attitudes”, a risk factor for the development of eating disorders. They include people who start a restrictive diet on impulse, fast for long periods, indulge in binge eating or feel guilty when they eat certain foods. A group [...]

A study conducted at the University of São Paulo helps explain why older people are more susceptible to the severe form of the disease and why it involves blood clotting disorders. An article published in NPJ Aging, a Springer Nature journal, reveals that natural production of auto-antibodies increases with age and that infection by SARS-CoV-2 can exacerbate production of auto-antibodies relating to auto-immune diseases, helping to explain why aging increases the [...]

Washington DC [US], August 30 (ANI): A review paper published in the journal Foods describes a study that provides an overview of studies on minimally processed vegetables (MPVs), with a particular focus on the Brazilian market. Data is presented on hygiene indicators and pathogenic microorganisms, especially Escherichia coli (the main indicator of fecal contamination), Salmonella spp., and Listeria monocytogenes, with prevalence rates ranging from 0.7 per cent to 100 per cent, 0.6 per cent [...]

Even mild COVID-19 can cause structural and functional alterations in the brain that may lead to neuropsychiatric disorders, such as anxiety, depression, fatigue and somnolence, as well as adverse effects on well-being, health and work capacity. This is the conclusion of studies on COVID-19 presented at the 9th BRAINN Congress organized by the Brazilian Institute of Neuroscience and Neurotechnology (BRAINN), a Research, Innovation and Dissemination Center (RIDC), held April 17–19 in [...]
