Researchers at the Federal University of Sao Carlos (UFSCar) in the state of Sao Paulo, Brazil, in partnership with colleagues at University College London in the UK have discovered an efficient, simple and inexpensive method of predicting the risk of functional disability in older people. They analyzed data from more than 3,000 over-sixties living in England and found that slowness of gait alone can be considered a predictor of loss of the capacity to perform the basic and instrumental [...]

In COVID-19 patients, obesity is the factor most associated with the development of endothelial dysfunction, a condition in which the blood vessels become unable to contract and relax adequately, increasing the risk of events such as heart attacks, thrombosis (blood clotting), and stroke. Endothelium refers to the thin sheet of cells lining the walls of arteries and veins, as well as the inside of the heart. Endothelial cells release substances that control vascular relaxation and contraction, [...]

Yellow fever is a non-contagious viral disease with two transmission cycles, sylvatic (in wild animals) and urban. Sylvatic yellow fever circulates among monkeys, and in Brazil is transmitted by mosquitoes of the genera Haemagogus and Sabethes, which bite an infected monkey and then infect others. Urban yellow fever circulates among humans and is transmitted by the mosquito Aedes aegypti (human-mosquito-human). Brazil has had no urban yellow fever cases since 1942, but the sylvatic version can [...]

Torquetenovirus (TTV) is without doubt one of the viruses most often discovered in the human organism. It’s also frequent in monkeys and home animals. Its presence has not been related to any identified illness, however its extreme replication is a signal that one thing is improper with the immune system. The correlation between excessive TTV load and immunosuppression has been used in medication in sure contexts, similar to monitoring transplant patients who take remedy to forestall [...]

Researchers at the University of Sao Paulo (USP) in Brazil have shown that a hypertonic saline solution inhibits replication of SARS-CoV-2, the virus that causes COVID-19, and have elucidated the biochemical mechanism involved. An article reporting the research is published in ACS Pharmacology & Translational Science. The study was performed in the laboratory using human epithelial lung cells infected with the virus., FAPESP Researchers at the University of Sao Paulo (USP) in Brazil have [...]

Sepsis is the leading cause of death in Brazil’s intensive care units (ICUs). Among patients who progress to the severe form of the disease, 40% die, and the survivors often suffer from cardiovascular and neurological complications, as well as a significant decline in immunity lasting for years after they are discharged from hospital., Sepsis is the leading cause of death in Brazil’s intensive care units (ICUs). Among patients who progress to the severe form of the disease, 40% [...]

A review of the scientific literature published by Brazilian researchers shows that pregnant women infected by the novel coronavirus run a higher risk of developing pre-eclampsia, a pregnancy complication characterized by persistent high blood pressure, usually in the second half of pregnancy or shortly after delivery. The disorder can cause serious harm to mother and baby. An article with the findings of the review is published in the journal Clinical Science. The authors analyzed a [...]

A study conducted at the University of Sao Paulo (USP) in Brazil shows that the incidence of infections by the novel coronavirus among professional soccer players in Sao 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., by Karina Toledo, FAPESP A study conducted at the University of Sao Paulo (USP) in Brazil shows that the incidence of infections by the novel coronavirus among professional soccer players in [...]
