Removal of the Active Pharmaceutical Substance Entecavir from Water via the Fenton Reaction or Action by the Cyanobacterium .

Entecavir (ETV) is an antiviral used to treat chronic infection caused by the hepatitis B virus, which affects approximately 250 million people worldwide. In order to mitigate the impacts of ETV on the environment, including potential harm to human health, this study evaluated the use of the Fenton-like reaction, which uses iron complexed with ethylenediaminetetraacetic acid (EDTA) at neutral pH, and the microbiological action of in removing ETV from the aqueous medium. Aqueous concentrations of 100 mg/L were subjected to Fenton-like degradation.

Non-adherence, discontinuation, and seroconversion among people on daily HIV pre-exposure prophylaxis (PrEP) in Brazil: a nationwide cohort study.

The goal of this study was to evaluate characteristics associated with Pre-exposure Prophylaxis for HIV infection (PrEP) non-adherence or discontinuation in Brazil and assess the association between these outcomes and HIV seroconversion. We used linked national dispensing and pathology data to identify people aged 14+ years initiating PrEP in 2018.

Biodegradation of the Antiretroviral Tenofovir Disoproxil by a Cyanobacteria/Bacterial Culture.

Tenofovir disoproxil fumarate (TDF) is an antiretroviral drug extensively used by people living with HIV. The TDF molecule is hydrolysed in vivo and liberates tenofovir, the active part of the molecule. Tenofovir is a very stable drug and the discharge of its residues into the environment can potentially lead to risk for aquatic species.

Does switching from multiple to single-tablet regimen containing the same antiretroviral drugs improve adherence? A group-based trajectory modeling analysis.

Combination Antiretroviral Therapy (cART) in single-tablet regimens (STR) is a simplification strategy that can potentially improve medication adherence and clinical outcomes. We conducted a retrospective cohort study of 1206 patients using efavirenz, tenofovir and lamivudine in multiple-tablet regimen who switched to the STR containing the same active ingredients in a southeast metropolis in Brazil. We measured adherence using the proportion of days covered (PDC≥95%) and evaluated this outcome before and after the switch using paired non-parametric statistics.

Which antiretroviral regimen is associated with higher adherence in Brazil? A comparison of single, multi, and dolutegravir-based regimens.

We evaluated adherence to highly active antiretroviral therapy (HAART) and its associated factors according to the type of regimen in patients initiating treatment in Belo Horizonte, Minas Gerais State, Brazil. We measured adherence using the eight items Morisky Therapeutic Adhesion Scale (MMAS-8) and compared the use of "backbone" tenofovir/lamivudine plus efavirenz one tablet once-daily (STR) or dolutegravir in multi-tablet once-daily (MTR-DTG), or other multi-tablet regimens (MTR-other). We conducted a multivariate logistic regression analysis to address factors associated with adherence.

New patient-reported outcome measure to assess perceived barriers to antiretroviral therapy adherence: the PEDIA scale.
