Article Synopsis
- Black/African American women with breast cancer face a higher mortality risk than other racial groups, despite having lower overall incidence rates, with very low advance care planning and code status documentation.
- The study analyzed data from over 7,500 women at the University of Chicago Medical Center between 2016 and 2021, using Cox regression to assess the impact of race on code status orders.
- Results showed that only 7.2% had code status documentation, with Black/African American patients being significantly more likely to have code status orders compared to other racial groups, highlighting ongoing racial disparities in breast cancer care.
Organisms require dietary macronutrients in specific ratios to maximize performance, and variation in macronutrient requirements plays a central role in niche determination. Although it is well recognized that development and body size can have strong and predictable effects on many aspects of organismal function, we lack a predictive understanding of ontogenetic or scaling effects on macronutrient intake. We determined protein and carbohydrate intake throughout development on lab populations of locusts and compared to late instars of field populations.

- The study demonstrated the ability of various crude plant peroxidases, particularly horseradish root (HRP) and pumpkin skin (PKS), to degrade mono- and polyfluorinated phenolic compounds effective for environmental cleanup.
- HRP showed decreased activity with more fluorinated substrates due to steric hindrance, while PKS maintained higher degradation rates, suggesting its larger active site allows for better interaction with these compounds.
- The successful library screening method identified high-activity samples, indicating its potential use for discovering new catalysts for the degradation of other fluorinated compounds in the quest for environmentally friendly biocatalytic solutions.
Article Synopsis
- Accurate diagnosis and treatment of complex cardiac tumors is challenging, especially for surgical resection, but 3D reconstruction and printing can enhance pre-operative planning and care.
- The study reports two patients with rare cardiac conditions, one with cardiac angiosarcoma and the other with IgG4-related disease, where 3D models aided in surgical strategies.
- Both patients experienced successful outcomes, with the angiosarcoma patient receiving chemotherapy and another surgery, while the IgG4 patient had complete tumor resection, demonstrating the utility of 3D printing in surgical planning.
The Environmental Protection Agency (EPA) of the United States recently released the first-ever federal regulation on per- and polyfluoroalkyl substances (PFASs) for drinking water. While this represents an important landmark, it also brings about compliance challenges to the stakeholders in the drinking water industry as well as concerns to the general public. In this work, we address some of the most important challenges associated with measuring low concentrations of PFASs in drinking water in the field in real drinking water matrices.
