STI and HIV screening decreased while positive test results increased during COVID-19: Study

New research from Boston Medical Center found that sexually transmitted infection (STI) and HIV testing declined at the onset of the COVID-19 pandemic, while there was an increase in positive test rates. Published in AIDS Patient Care and STDs, the study aimed to understand how the pandemic affected infection screening in safety-net settings given rising STI and HIV cases and the significant and inequitable impacts of the COVID-19 pandemic on already marginalized populations.

Fluid flow in the brain can be manipulated by sensory stimulation

Researchers at Boston University, U.S. report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. Led by Stephanie Williams, and publishing in the open access journal PLOS Biology on March 30, the study demonstrates that manipulating blood flow in the brain with visual stimulation induces complementary fluid flow. The findings could impact treatment for conditions like Alzheimer’s disease, which have been associated with declines in cerebrospinal fluid flow.

Study shows autism may be linked to different perceptions of movement in infancy

A new study from researchers at Uppsala University and Karolinska Institutet shows that children who go on to develop symptoms of autism have different activity in their brain’s visual cortex from as early as five months when looking at certain types of movement. This finding may indicate that autistic people perceive their surroundings in a different way even from a very young age, which could affect their development and learning.
