C. difficile is a bacterium that causes intestinal infection, most frequently after the use of antibiotics. It is thought to affect almost half a million people in the United States every year. Credit: CDC A study reported in Proceedings of the National Academy of Sciences (PNAS) shows how the presence of a specific protein called IL-22BP affects the composition of the gut microbiota and the body’s response to bacterial infection. “We discovered that mice that don’t [...]

Memory loss and attention deficit are frequent complaints of people who have survived severe COVID-19, but these and other cognitive impairments have also been observed in mild cases more than 18 months after the start of the infection, according to a study by researchers at the University of São Paulo (USP) in Brazil. The study is published in the journal BMC Psychology. The findings highlight the need for more comprehensive rehabilitation to address the enduring cognitive impacts of [...]

A Brazilian study assessed 237 patients treated at the University of São Paulo’s general and teaching hospital. The researchers found that 92% still had lung damage two years after discharge, with fibrosis (33% of cases) arousing most concern. Peer-Reviewed Publication FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO A study conducted in Brazil points to long-term functional abnormalities in their lungs two years after hospital discharge in [...]

In experiments with mice, researchers at the State University of Campinas in Brazil and the Pasteur Institute in Lille (France) found that viral load and inflammation decreased in animals infected by influenza virus when they were given the substance. A molecule produced naturally in the gut can help prevent and even treat influenza, according to a study reported in the journal Gut Microbes by researchers at the State University of Campinas (UNICAMP) in São Paulo state, Brazil, and [...]

Aerobic training is known to regulate blood pressure more effectively when practiced in the evening than in the morning. Researchers who conducted a study of elderly patients at the University of São Paulo’s School of Physical Education and Sports (EEFE-USP) in Brazil concluded that evening exercise is better for blood pressure regulation thanks to improved cardiovascular control by the autonomic nervous system via a mechanism known as baroreflex sensitivity. The study is published [...]

In an article published in the journal Psychiatry Research, Brazilian scientists describe a number of molecular alterations found in the blood and brain tissue of individuals who committed suicide. According to the authors, the study aimed to identify susceptibility factors and potential targets for innovative pharmacological intervention.

A 30-minute walk at moderate intensity temporarily reduced blood pressure in women with rheumatoid arthritis, not only at rest but also under stress. This was the conclusion drawn from a study involving physical and cognitive tests conducted at the University of São Paulo (USP) in Brazil. Rheumatoid arthritis is an autoimmune inflammatory disease affecting synovial joints and causing pain, swelling, and progressive physical incapacity. People with rheumatoid arthritis also tend to [...]
