Comparative outcomes of direct-acting antiviral treatment in patients with HIV-Hepatitis C co-infection: insights from a single center experience in Colombia.

Background: Direct-acting antivirals (DAA) were introduced to Latin America with the aim of eliminating hepatitis C (HCV) in the region. There are scarce data on the outcomes of people living with HIV and HCV treated with these medications in Colombia. This study compares the outcomes of patients with HIV-HCV co-infection and HCV mono-infection treated with DAAs.

Treatment of synthetic dye baths by Fenton processes: evaluation of their environmental footprint through life cycle assessment.

Inorganic and organic constituents present in textile effluents have a noticeable effect on the performance of Fenton processes. However, studies have been focused on simple wastewater matrices that do not offer enough information to stakeholders to evaluate their real potential in large-scale facilities. Chemical auxiliaries, commonly present in textile wastewaters (NaCl = 30 g/L, NaCO = 5 g/L, and CHCOONa = 1 g/L), affect both the economic and environmental performance of the process because they increase the treatment time (from 0.

How does intensification influence the operational and environmental performance of photo-Fenton processes at acidic and circumneutral pH.

This study evaluates the technical, economical, and environmental impact of sodium persulfate (NaSO) as an enhancing agent in a photo-Fenton process within a solar-pond type reactor (SPR). Photo-Fenton (PF) and photo-Fenton intensified with the addition of persulfate (PFPS) processes decolorize 97% the azo dye direct blue 71 (DB71) and allow producing a highly biodegradable effluent. Intensification with persulfate allowed reducing treatment time in 33% (from 120 to 80 min) and the consumption of chemical auxiliaries needed for pH adjustment.
