To meet wastewater treatment quality standards for reuse, integrating advanced oxidation processes (AOPs) with Decentralized Wastewater Treatment Systems (DEWATS) is promising. This study aimed to optimize AOPs (ozonolysis, UV photolysis, TiO photocatalysis) for polishing anaerobic filter (AF) effluent from DEWATS, as an alternative to constructed wetlands. Metrics included pathogen reduction efficiency, post-disinfection regrowth, and effects on physical parameters (pH, EC, turbidity), organic matter (soluble COD, BOD, DOC, humic), and nutrient concentration (ammonium, nitrates, ortho-P).

Thus, several HIV prevention interventions have been implemented, though to a narrower extent compared with other most at-risk populations. Consequently, the effectiveness of such interventions is not well understood.

However, the risk of pathogens regrowing in treated effluents can endanger public health if reused in agriculture, attracting stringent reuse standards. While advanced oxidation processes (AOPs) promise to reduce pathogens, eliminating regrowth potential in AOP-treated effluents requires further scrutiny.

- - The study examined gender representation in clinical trials for FDA-approved anticancer drugs from 1998-2018, focusing on participation rates of women compared to men across various cancer types.
- - Findings indicated that women constituted only 40.7% of participants in 148 trials, with significant under-representation in trials for gastric, liver, and lung cancers, while sex-specific efficacy and safety data were rarely reported (only 4% of trials).
- - Despite low female enrollment, there was no correlation between the percentage of women recruited and drug efficacy, highlighting a persistent gap in gender representation in cancer research.
Objectives: The purpose of this study was to systematically summarise the empirical evidence on the prevalence of HIV among long-distance truck drivers (LDTDs) from all parts of the world.
Design: A systematic review and meta-analysis were conducted.
