The reemergence of dengue virus serotype 3 (DENV-3) in Brazil after 17 years could help worsen fresh outbreaks of the disease there since the population is not immunized against this serotype, and serotypes 1 and 2 (DENV-1 and DENV-2) continue to circulate. The warning features in an article written by researchers at the São José do Rio Preto Medical School (FAMERP) in São Paulo state, and published in the Journal of Clinical Virology. "The last [...]

From a study that analyzed brain images of more than 2,500 people with Parkinson's disease in 20 different countries, scientists were able to identify patterns of neurodegeneration and create metrics for each of the five clinical stages of the disease. The work, published in NPJ Parkinson's Disease, represents a leap forward in the understanding of the disease. The analysis and volume of data obtained in the study could lead to important developments, not only in terms of [...]

The scenario is common. An elderly person seems to be in good health until one day they suffer a fall and from then on their quality of life begins to deteriorate. Even if there are no serious consequences such as injuries, fractures or head trauma, falls usually lead to reduced mobility and consequently to a loss of independence and autonomy. The problem is so worrisome – falls are the second leading cause of injury-related death among adults aged 65 and over in the world, according [...]

Expanding aquaculture in the Amazon could provide nutritional and economic benefits at a fraction of the environmental cost of cattle grazing, according to a Jan. 24 paper in Nature Sustainability from Cornell researchers and colleagues in the U.S. and Brazil. Such expansion could also come with risks, especially the potential introduction of harmful non-native species, the paper finds. "Cattle production is one of the most important drivers of deforestation in the Amazon," said Felipe [...]

In 2017, a tragic incident unfolded in a Nevada hospital. A woman, admitted for pneumonia, tragically succumbed to multiple organ failure and sepsis. The culprit? A strain of bacteria that had developed resistance to a staggering 26 different antibiotics. These superbugs, or antibiotic-resistant bacteria, stand as one of the most pressing public health threats globally. Joining the effort to fight these deadly pathogens, researchers at Texas A&M have now shown that curcumin, the compound [...]

A groundbreaking discovery by an international research team has revealed the existence of an advanced irrigation and drainage system used by the pre-Columbian Casarabe society in the Amazon. This system enabled year-round maize cultivation, reshaping previous understandings of agriculture in the region. The finding challenges earlier theories that dismissed the possibility of large-scale monoculture farming in the Amazon. The study, published in Nature, details how the Casarabe people of [...]

Using a single-cell sequencing technique, Brazilian researchers have created the first cell atlas of focal cortical dysplasia (FCD), a malformation of the cerebral cortex that leads to drug-resistant epilepsy. These cases are most common in children and adolescents, accounting for up to 50% of epilepsy surgeries in this age group. With the atlas, it was possible to characterize the different cell types present in the brain lesion and determine which ones are involved in the disease. The [...]

A new study by a team of researchers from the UK and Brazil has revealed a strong connection between childhood trauma and the development of psychiatric disorders in adolescents living in low-and middle-income countries.   The research findings are based on the 2004 Pelotas Birth Cohort, Brazil, which has tracked more than 4,000 children born in Pelotas, a city in the southern state of Rio Grande do Sul, from birth to age 18. Published in The Lancet Global Health, the study looked at [...]
