Advanced imaging uncovers hidden metastases in high-risk prostate cancer cases

A new study found that nearly half of high-risk prostate cancer patients have metastatic disease when evaluated with advanced PSMA-PET imaging, suggesting traditional imaging may underestimate cancer spread. This challenge the interpretation of previous studies like EMBARK trial, and support the inclusion of PSMA-PET for patient select...

Multilingualism improves crucial cognitive functions in autistic children

A new study reveals multilingualism enhances executive function skills, including focus, understanding perspectives, communication, and reduces repetitive behaviors in both autistic and non-autistic children. Parents of multilingual households report stronger overall executive function compared to mono-lingual households.

Emergency department physicians vary widely in their likelihood of hospitalizing a patient, even within the same facility

A new study found that emergency department physicians differ in their likelihood of hospitalizing patients, with those who admit more patients being discharged sooner but not less likely to die. The study suggests that differences in physician decision-making drive these variations, rather than patient health.

Study supports new blood-based biomarker to detect early brain changes leading to cognitive impairment and dementia

A new blood-based biomarker, placental growth factor (PlGF), has been identified as a potential tool for detecting early brain changes associated with cognitive impairment and dementia. Elevated PlGF levels were found to be linked to increased vascular permeability, leading to white matter injury and subsequent cognitive decline.

People from some racial and ethnic groups may face barriers to obtaining obesity medications

A new study found significant disparities in the use of obesity-management medications among different racial and ethnic groups. People of Asian, Black, and Hispanic descent were significantly less likely to use these medications compared to whites, even after adjusting for income, education, health insurance coverage, and clinical need.
