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 [...]

A study involving 22 Parkinson's disease (PD) patients has shown that use of the dopaminergic drug levodopa improves sleep quality. When the patients took the drug, the number of times they woke up during the night fell 25% and the amount of time they remained awake fell 30% on average. The investigation was conducted with FAPESP's support by researchers at São Paulo State University (UNESP) in Brazil, and the University of Grenoble Alpes (UGA) in France. An article reporting [...]

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 [...]

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 [...]

A study by scientists at three Brazilian institutions reported in the journal Archives of Psychiatric Nursing found that practicing mindfulness helped nurses manage their levels of anxiety and stress.

For the first time, researchers have identified a group of neurons deep in the brain that are associated directly with compulsive eating and food craving. The discovery is reported in an article published in Nature Communications by researchers at the University of California, Los Angeles (UCLA) in the United States and the Federal University of the ABC (UFABC) in São Bernardo do Campo, São Paulo state (Brazil).  The neurons are located in the [...]

Researchers at the University of São Paulo (USP) in Brazil have shown for the first time that SARS-CoV-2, the virus that causes COVID-19, can remain in the sperm of patients for up to 90 days after hospital discharge and up to 110 days after the initial infection, reducing semen quality. The study is reported in an article published in the journal Andrology. The authors suggest that people who plan to have children should observe a period of “quarantine” after [...]
