Private, public, and bottled drinking water: Shared contaminant-mixture exposures and effects challenge.

Background: Humans are primary drivers of environmental-contaminant exposures worldwide, including in drinking-water (DW). In the United States, point-of-use DW (POU-DW) is supplied via private tapwater (TW), public-supply TW, and bottled water (BW). Differences in management, monitoring, and messaging and lack of directly-intercomparable exposure data influence the actual and perceived quality and safety of different DW supplies and directly impact consumer decision-making.

Investigation of Biological Activity of Fucoidan and Laminarin as Bioactive Polysaccharides from Irish Brown Macroalgae.

This study aimed to investigate the biological activity of crude and purified laminarin and fucoidan samples extracted from Irish brown macroalgae species and . The antioxidant capacity of the samples was evaluated using the 2,2-diphenyl-1-picrylhydrazyl and ferric-reducing antioxidant power assays. The anti-inflammatory potential of the samples was analysed using the cyclooxygenases inhibition activity, and the antidiabetic activity was evaluated using a dipeptidyl peptidase-4 inhibitor screening assay.

State of the science on assessing developmental neurotoxicity using new approach methods.

The workshop titled State of the Science on Assessing Developmental Neurotoxicity Using New Approach Methods was co-organized by University of Maryland's Joint Institute for Food Safety and Applied Nutrition (JIFSAN) and the U.S. Food and Drug Administration's (FDA) Center for Food Safety and Applied Nutrition (CFSAN; now called the Human Foods Program), and was hosted by FDA in College Park, MD on November 14-15, 2023.

Assessing Adherence to Posttraumatic Stress Disorder Screening in Young Stroke Survivors.

Background: Over 795 000 US people per year experience a stroke, and 10% are younger than 50 years. After a stroke, posttraumatic stress disorder (PTSD) affects 10% to 30% of those patients and may compromise a survivor's secondary prevention compliance. At an inner-city clinic in Maryland where up to 300 young adult stroke survivors are followed, zero patients were screened for PTSD.
