An Oxford Nanopore Technology-Based Hepatitis B Virus Sequencing Protocol Suitable for Genomic Surveillance Within Clinical Diagnostic Settings.

Chronic Hepatitis B Virus (HBV) infection remains a significant public health concern, particularly in Africa, where the burden is substantial. HBV is an enveloped virus, classified into ten phylogenetically distinct genotypes (A-J). Tests to determine HBV genotypes are based on full-genome sequencing or reverse hybridization.

Cognitive performance, neuropsychiatric symptoms, and cerebrospinal fluid viral control following programmatic switch from efavirenz-based to dolutegravir-based antiretroviral therapy in South Africa (CONNECT): a prospective cohort study.

Background: Both efavirenz and dolutegravir have been associated with neuropsychiatric side-effects and cognitive impairment. Furthermore, cerebrospinal fluid (CSF) HIV RNA escape has not been comprehensively studied in African populations. We aimed to examine changes in cognition, neuropsychiatric symptoms, and CSF viral control associated with the widespread switch from efavirenz-based to dolutegravir-based antiretroviral therapy (ART).

Virological impact of HIV drug-resistance testing in children, adolescents, and adults failing first-line ART in Tanzania.

Background: Prospective data on the effectiveness of resistance testing in informing treatment decisions and outcomes in with first-line failure in these settings is limited. This study aimed to assess the virological impact of HIV drug-resistance testing in patients with virological failure in Tanzania.

Methods: Participants were randomly assigned to either the control or the experimental group.
