Unveiling the Truth of Interactions between Microplastics and Per- and Polyfluoroalkyl Substances (PFASs) in Wastewater Treatment Plants: Microplastics as a Carrier of PFASs and Beyond.
Environ Sci Technol
January 2025
State Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences, Nanjing 211135, China.
Microplastics (MPs) and per- and polyfluoroalkyl substances (PFASs) are ubiquitous contaminants in environments, yet their co-occurrence and interactions remain insufficiently understood. In this study, we confirmed the concurrent presence of MPs and PFASs and their distinct distribution patterns in a wastewater treatment plant (WWTP) through a comprehensive sampling and analysis effort. Significant correlations ( < 0.

AIDS Care
February 2025
Department of Health, Behavior and Society, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA.
Disclosing one's HIV status or drug use in healthcare settings has significant implications for public and individual health. It is related to reduced occupational risk of infection for medical providers, improved care, reduction in disease transmission, and other clinical benefits for patients. However, disclosure can be challenging and problematic due to its discrediting aspects.

- People who inject drugs often face hospital admissions due to substance use complications and frequently continue using nonprescribed drugs while hospitalized, which can lead to increased health risks.
- Punitive and abstinence-based approaches to manage drug use in hospitals disproportionately harm vulnerable communities, especially Indigenous peoples affected by systemic discrimination and colonial legacies.
- To improve care, Canadian hospitals should adopt harm reduction strategies, provide cultural safety training for clinicians, and collaborate with academic institutions to support the recruitment and retention of Indigenous healthcare professionals.
Roodmus: a toolkit for benchmarking heterogeneous electron cryo-microscopy reconstructions.

Department of Bionanoscience, Kavli Institute of Nanoscience, Delft University of Technology, 2629 HZ Delft, The Netherlands.
Conformational heterogeneity of biological macromolecules is a challenge in single-particle averaging (SPA). Current standard practice is to employ classification and filtering methods that may allow a discrete number of conformational states to be reconstructed. However, the conformation space accessible to these molecules is continuous and, therefore, explored incompletely by a small number of discrete classes.

Alcohol Clin Exp Res (Hoboken)
December 2024
Department of Anesthesiology, University of Minnesota, Minneapolis, Minnesota, USA.
Background: Alcohol is a commonly used substance associated with significant public health consequences. Treatment is often stigmatized and limited with regard to both access and affordability, demonstrating the need for innovations in alcohol treatment. Accelerometer sensors can detect drinking without user input and are widely incorporated into wearable devices, increasing accessibility and affordability.
