Background: We evaluated reporting of diagnostic test accuracy (DTA) systematic reviews using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-DTA and PRISMA-DTA for abstracts.

Methods: We searched MEDLINE for recent DTA systematic reviews (September 2023-Mar 2024) to achieve a sample size of 100. Analyses evaluated adherence to PRISMA-DTA (and abstracts), on a per-item basis.

Article Synopsis
  • Metformin, a commonly prescribed diabetes medication, is often detected in wastewater and surface waters due to its stability and poor breakdown, potentially harming aquatic ecosystems.
  • An 8-week experiment in a freshwater lake tested the impact of metformin at concentrations of 0, 5, and 50 μg/L on various aquatic organisms, including microbes and zooplankton.
  • Results showed that metformin remained stable in water, with no significant adverse effects on aquatic communities or organisms, suggesting limited environmental impact despite its high concentration in wastewater.

Microorganisms capable of direct or mediated extracellular electron transfer (EET) have garnered significant attention for their various biotechnological applications, such as bioremediation, metal recovery, wastewater treatment, energy generation in microbial fuel cells, and microbial or enzymatic electrosynthesis. One microorganism of particular interest is the organohalide-respiring bacterium strain CBDB1, known for its ability to reductively dehalogenate toxic and persistent halogenated organic compounds through organohalide respiration (OHR), using halogenated organics as terminal electron acceptors. A membrane-bound OHR protein complex couples electron transfer to proton translocation across the membrane, generating a proton motive force, which enables metabolism and proliferation.
