Cancer incidence trends in 2021 largely returned to what they were before the COVID-19 pandemic, according to a study by researchers at the National Institutes of Health (NIH). However, there was little evidence of a rebound in incidence that would account for the decline in diagnoses in 2020, when screening and other medical care was disrupted. One exception was breast cancer, where the researchers did see an uptick in diagnoses of advanced-stage disease in 2021.

A new study has revealed that despite the recent pandemic, outbreak detection efforts remain under-resourced in South and Southeast Asia, with only about half the countries reviewed having integrated pathogen genomic surveillance initiatives in their national plans. The study also identifies key priorities to enhance the preparedness of the region against future pandemics.

Researchers analyzed 193 patients from the Vietnam Head Injury Study with penetrating traumatic brain injury to determine if the location of shrapnel damage to their brains influenced risk of developing PTSD. Damage to areas connected to the amygdala was associated with a lower chance of developing PTSD. The study suggests lesions that could protect against PTSD map to a specific brain circuit connected to the amygdala and the medial prefrontal cortex.

Parkinson's disease, a debilitating nervous system disorder, is treated with medications that sometimes cause impaired decision-making and poor impulse control. Now, researchers have identified a structure in the brain called the external globus pallidus which may be responsible for this side effect, paving the way for new treatments.
