A pilot-scale study on sludge treatment reed beds investigated the combined effects of earthworms and Arundo donax on sewage sludge dewatering and residual sludge quality. Four units were tested: one planted with earthworms, one planted without earthworms, one unplanted with earthworms, and one control, each unit replicated. Over a year, 24 cycles of sludge (dry and volatile solid contents of 24.

Purpose: To determine whether microstructural retinal changes, tumor features, and polymorphism are correlated with clinically detectable treatment-associated cognitive dysfunction (TACD) in patients with lower-grade gliomas.

Design: Cohort study.

Participants And Controls: Sixteen patients with lower-grade glioma at a United States academic ophthalmology department between January 2021 and November 2023.

Glioblastoma is a highly aggressive brain tumor with poor prognosis despite surgery and chemoradiation. The visual sequelae of glioblastoma have not been well characterized. This study assessed visual outcomes in glioblastoma patients through neuro-ophthalmic exams, imaging of the retinal microstructures/microvasculature, and perimetry.

Article Synopsis
  • The study assessed how earthworms affect water quality in sludge treatment systems with four different setups.
  • Incorporating earthworms significantly reduced total suspended solids, chemical oxygen demand, and nutrients like nitrate and phosphorus, while also increasing plant biomass by 43%.
  • After six months, the earthworm-planted systems showed impressive removal efficiencies, achieving near-complete removal of TSS and COD, although some nutrient levels still exceeded reuse limits.
