Thompson provides a comprehensive review of current research on microplastic contamination in freshwater environments. The article synthesizes findings from over 150 studies conducted across different geographical regions, identifying primary sources including textile fibers, tire wear particles, and degraded larger plastics. Thompson documents the distribution patterns of microplastics in rivers, lakes, and groundwater systems, noting higher concentrations near urban centers and industrial areas.

Jackson and Sato conduct a meta-analysis of 34 clinical trials examining virtual reality applications for acute and chronic pain management. The authors systematically evaluate the quality of included studies and calculate effect sizes for various VR interventions. Their findings suggest moderate to strong effects for acute procedural pain, particularly in burn care, with more variable results for chronic conditions. The methodological rigor is impressive, though sample sizes in primary studies remain a limitation.
