Scientists have uncovered a new mechanism that could help explain why some Covid infected people develop a potentially fatal systemic inflammation, according to a study. Researchers at the University of Sao Paulo (USP) in Brazil have found that severe COVID-19 is associated with an imbalance in an important immune system signalling pathway. The researchers detected "dysregulation", or a dysfunctional regulation, of the immune system mediated by adenosine triphosphate (ATP), one [...]

Metabolic syndrome is a cluster of conditions that heighten the risk of cardiovascular disease, stroke and diabetes, including hypertension, high blood sugar, excess body fat around the waist and abnormal cholesterol levels. According to a study, reducing protein consumption can help regulate metabolic syndrome and some of its key symptoms, such as obesity, diabetes, and high blood pressure (hypertension). An article reporting the study is published in the journal [...]

A study shows how SARS-COV-2 infects brain cells called astrocytes, causing structural changes in the brain. Infection with SARS-CoV-2 can cause brain alterations and neurocognitive dysfunction, particularly in long COVID-19 syndrome, but the underlying mechanisms are elusive. Daniel Martins-de-Souza and colleagues used MRI to compare brain structure in 81 study participants recovering from a mild COVID-19 infection and 81 healthy individuals. The authors found that the former group [...]

Sao Paula [Brazil], April 13 (ANI): Researchers at the University of Sao Paulo have calculated the impact of adolescents consuming ultra-processed foods on the risk of obesity. The findings of the study were published in the journal, ‘Journal of the Academy of Nutrition and Dietetics’. There are 3,587 adolescents aged 12-19 who took part in the 2011-16 National Health and Nutrition Examination Survey (NHANES). They divided participants in the study into three groups according [...]

A new study published in the Frontiers in Medicine Journal has claimed that the SARS-CoV-2 virus may remain active for more than what is now believed. These are, however, not regular cases and have been terms as atypical cases. Out of 38 Brazillian patients, who have been tracked for this study, two men and a woman were continuously found positive for more than 70 days. "Based on this result, we can say that about 8 per cent of people infected by SARS-CoV-2 may be able to transmit the [...]

The study has been published in the ‘Frontiers in Medicine Journal’. The atypical case of infection by SARS-CoV-2 was part of a study involving 38 Brazilian patients followed on a weekly basis between April and November 2020 by researchers affiliated with the Pasteur-USP Scientific Platform, a partnership between France’s Pasteur Institute, the University of Sao Paulo (USP) and Oswaldo Cruz Foundation (Fiocruz) in Brazil. The patients were followed until they tested [...]

The findings of a new study suggest that cardiopulmonary exercise testing (CPET), also known as ergo spirometry, can be used for the early detection of respiratory disorders in overweight and obese individuals. This is the main finding of a study by Brazilian researchers who set out to assess the influence of obesity on the physiological responses obtained in CPET. The findings of the study were published in the journal 'PLOS ONE'. Most of the authors are [...]

Our comparative analysis showed loss of gait speed occurring mainly when abdominal fat and weak muscles were associated. Gait speed didn't decline so sharply in older people who had only abdominal fat or only weak muscles," said last author of a paper on the study. A new study has found that the dangerous combination of weak muscles and abdominal fat can lead to a significant loss of gait speed in older people. The findings of the study were published in the journal 'Age and [...]

The study, carried out by the Sau Paulo state government, was carried out in the small town of Serrana after 75% of adults were covered with a second shot. The town has a population of 45,000.
