In an article published in JAMA Network Open, researchers at the University of São Paulo's Medical School (FM-USP) report on a study involving 774 men and women who followed a vegan diet in Brazil. Their findings show that, on average, the participants consumed the recommended amount of proteins and essential amino acids, and that their diet consisted largely of unprocessed and minimally processed foods. However, participants who consumed proportionally lower levels [...]

According to an article published in the journal PLOS Pathogens, severe COVID-19 patients can be divided into two distinct groups: those with a high viral load and relatively little inflammation, and those who continue to suffer from inflammatory complications even after the virus has been completely eliminated. The article describes a study conducted in Brazil by researchers at the University of São Paulo (USP) who analyzed lung autopsies from 47 fatal COVID-19 cases alongside their [...]

Cheese could be healthier in the future now that microbiologists in Brazil have discovered three novel strains of probiotic bacteria in samples of traditional cheeses. Probiotics are live microorganisms that, when eaten in food, may remain in the gut. People who have lots of—and lots of different types of—probiotic bacteria and yeasts in their gut are thought to have healthy microbiomes, i.e., microbial communities. A healthy gut microbiome is associated with good mental [...]

Research conducted at the Center for Dairy Technology (Tecnolat) in Campinas, São Paulo state, Brazil, has identified lactic acid bacteria (LAB) that have probiotic properties and are beneficial to human health in samples of traditional Brazilian cheeses. Tecnolat is part of the Food Technology Institute (ITAL), an arm of the São Paulo State Department of Agriculture and Supply. The findings are published in the journal Current Microbiology. The researchers analyzed three [...]

Brazilian researchers have investigated the effects of delivery date manipulation to avoid the Carnival holiday. Their findings suggest that Brazilian women are giving birth too early, impairing the health of their babies. The evidence shows that many cesarean sections scheduled to take place during the Carnival holiday in Brazil are moved up or postponed. Researchers at INSPER, a private higher education and research institution in São Paulo city, investigated the effects of this [...]

An article published in the journal Current Biology describes experiments that mapped a brain circuit responsible for instantly detecting threats and forming memories of fear. "We were interested in locating a brain region associated with fear signaling and finding out how it could identify environments previously related to physical or predatory threats, such as a place where the individual underwent an aversive physical stimulus," said Newton Sabino Canteras, full professor in [...]

To evade the human host's immune response, SARS-CoV-2, the coronavirus that causes COVID-19 uses the machinery of defense cells to induce the expression of unproductive isoforms of key antiviral genes—variant forms of genes that result from disrupted splicing or transcription processes and do not code for functional (protective) proteins. This is a key finding of a study conducted by researchers at the Albert Einstein Jewish Brazilian Hospital (HIAE), the University of São [...]

A study conducted at the Federal University of São Carlos (UFSCar), in the state of São Paulo, Brazil, shows that tests of functional mobility and muscle strength can be adapted so that they can be performed at home under remote supervision by health professionals, especially for older people with dementia. The telehealth protocol also involves training for caregivers. Tests of functional mobility and muscle strength are widely used by physical therapists and geriatricians to [...]

Researchers in Brazil who analyzed samples from a 46-year-old patient in the Northeast state of Maranhão found an amphotericin B-resistant strain of the parasite Leishmania amazonensis circulating for the first time in the country. Amphotericin B is widely used to treat cutaneous leishmaniasis, a skin infection caused by sandfly bite. The disease is characterized by skin lesions that persist for months but can be cured. In the case in question, however, the patient had the diffuse [...]
