Objectives: To evaluate the histopathological changes in the liver after oral antiviral therapy in patients with chronic hepatitis B.
Methods: A total of 79 HBeAg-negative and positive patients who had been on lamivudine, entecavir, or tenofovir disoproxil for at least 3 years prior to inclusion were enrolled between March 2015 and 2016, retrospectively. There were 23 patients on lamivudine, 21 patients on entecavir, and 35 on tenofovir. All patients underwent a follow-up liver biopsy. Biochemical, serological, virological and histopathological data were recorded in all patients and were compared after at least 3 years of treatment with oral antiviral agents. Results: Histological activity index scores were reduced in patients who received lamivudine (p=0.011), entecavir (p=0.002), and tenofovir (p=0.001). Also, in contrast with a significant improvement in fibrosis scores in lamivudine (p=0.033) and tenofovir (p=0.001) groups no improvements were found in patients who received entecavir (p=0.090). Conclusion: Long term treatment with oral antiviral agents was associated with biochemical, virological, serological, and histopathological improvements. Long-term use of anti-viral agents as well as continuous suppression of HBV DNA are prerequisites for histopathological improvement.

Barriers to PrEP use and adherence among adolescent girls and young women in Eastern, Southern, and Western Africa: a scoping review.
BMC Womens Health

Department of Public Health Institute of Tropical Medicine, Antwerp, Belgium.
Background: Adolescent girls and young women (AGYW) are disproportionately affected by HIV. Globally, in 2022, an estimated 4000 AGYW 15-24 were newly infected with HIV weekly, and nearly 78% of these infections occurred in sub-Saharan Africa. Oral Pre-Exposure Prophylaxis (PrEP) is a key HIV prevention option within an overall HIV combination prevention approach with an efficacy of over 90% when taken correctly.

Anticipated facilitators and barriers for long-acting injectable antiretrovirals as HIV treatment and prevention in Vietnam: a qualitative study among healthcare workers.
BMC Infect Dis
December 2024
Department of Medicine, Beth Israel Deaconess Medical Center, Boston, USA.
Background: Long-acting injectable antiretrovirals (LAI-ARVs) for HIV prevention and treatment have been demonstrated in clinical trials to be non-inferior to daily oral medications, providing an additional option to help users overcome the challenges of daily adherence. Approval and implementation of these regimens in low- and middle-income settings have been limited.
Method: This study describes the anticipated barriers and facilitators to implementing LAI-ARVs in Vietnam to inform future roll-out.
Production of virus-like particles of FMDV by 3C protease cleaving precursor polyprotein P1 in vitro.

Nonstructural protein 3C, a master protease of Picornaviridae, plays a critical role in viral replication by directly cleaving the viral precursor polyprotein to form the viral capsid protein and antagonizing the host antiviral response. Additionally, 3C protease, as a tool enzyme, is involved in regulating polyprotein expression. Here, the 3C mutant gene (3Cm), fused with a small ubiquitin-like modifier (SUMO) tag at the N-terminal and featuring a mutation at position 127, was inserted into the cold-shock plasmid pCold of Escherichia coli for expression.

Introduction: Defining the prevention needs, motivations, and gender dynamics influencing adolescent and young people's (AYP's) healthcare access is a key component to successful PrEP (pre-exposure prophylaxis for HIV prevention) implementation. WHO encourages a strong people-cantered approach to healthcare delivery, and this is particularly emphasized for HIV services. Enhanced youth engagement is needed to ensure that interventions are tailored to the specific needs and preferences of youth populations.
