Physical exercise practiced by patients submitted to bariatric surgery acts on brain regions involved in food intake, reducing hunger or accelerating satiety, for example. This was the result observed in a clinical trial conducted at Hospital das Clínicas (HC), the hospital complex run by the University of São Paulo’s Medical School (FM-USP) in Brazil. An article on the study, pointing to positive effects of exercise on obesity-related conditions in post-bariatric patients, [...]

The COVID-19 pandemic and the situations of stress and sadness associated with it have not significantly increased the prevalence of depression and anxiety among participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brazil) who live in the city of São Paulo. ELSA-Brazil has been monitoring the overall health of 15,000 civil servants at six public universities and research centers in Brazil since 2008. The survey on mental health during the pandemic was conducted in [...]

A study conducted at the University of São Paulo (USP) in Brazil shows that the incidence of infections by the novel coronavirus among professional soccer players in São Paulo state during the 2020 season was 11.7%, the same as among health workers in the front line of the response to the pandemic. To arrive at this number, the researchers retrospectively analyzed almost 30,000 RT-PCR tests performed on swabs from 4,269 athletes during eight tournaments of the São Paulo [...]

A study conducted in the Una Biological Reserve in the state of Bahia, Brazil, shows that in a habitat with high hunting pressure the risk of predation has such a significant impact on the behavior of the Yellow-breasted capuchin monkey Sapajus xanthosternos that it even avoids areas offering an abundant supply of plant biomass and invertebrates, its main sources of food. An article reporting the findings of the study is published in the American Journal of [...]

The fungus Fusarium verticillioides is one of the causes of red rot, the most serious sugarcane disease. Losses average around USD 1 billion per harvest in Brazil alone. The traditional approach to the etiology of this disease is that it is triggered by Diatraea saccharalis, a moth usually referred to as the sugarcane borer. In the caterpillar stage, this insect bores into the stem of the plant, which is later infected opportunistically by the fungus. However, a study conducted in [...]

Brazilian researchers have simultaneously demonstrated the mechanism linking high blood pressure to elevated intracranial pressure, validated a non-invasive intracranial pressure monitoring method, and proposed a treatment for high blood pressure that does not affect intracranial hypertension. The study was supported by FAPESP and involved collaboration between researchers at São Paulo State University (UNESP) and Brain4care, a startup based in São Carlos. It could result in [...]

An article published in Frontiers in Immunology suggests that sepsis can cause alterations in the functioning of defense cells that persist even after the patient is discharged from hospital. This cellular reprogramming creates a disorder the authors call post-sepsis syndrome, whose symptoms include frequent reinfections, cardiovascular alterations, cognitive disabilities, declining physical functions, and poor quality of life. The phenomenon explains why so many patients who survive sepsis die [...]

All three species of manatee now present on Earth share a common ancestor from which they split some 6.5 million years ago, when a huge lake in Amazonia, then linked to the Caribbean, was cut off from the sea. The African manatee Trichechus senegalensis is not as genetically close to the West Indian manatee T. manatus as was thought, and adaptation to this complex environment by the Amazonian manatee T. inunguis has left at least one mark in its genetic code. These are key findings of a study [...]

The risk of developing atherosclerosis – a narrowing of the arteries as cholesterol plaque builds up, leading to obstruction of blood flow – is higher for people with autoimmune rheumatic diseases than for the general population. As a result, they are more likely to have heart attacks and other cardiovascular disorders. The good news, according to a new study published in Rheumatology, is that regular exercise is a powerful weapon against vascular dysfunction in these patients. In [...]
