No virological failure in patients living with HIV with past NNRTI resistance-associated mutations switched to doravirine-containing regimens.

Background: Doravirine is licensed in patients living with HIV (PWH) harbouring no prior resistance to any NNRTIs. We aimed to evaluate in real life the efficacy of doravirine with prior NNRTI virological failure and NNRTI resistance-associated mutations (RAMs).

Methods: This observational study included PWH switched to a doravirine-containing regimen between 30 September 2019 and 1 May 2022, with an HIV-1 RNA of ≤50 copies/mL and past NNRTI-RAMs.

Clearance of archived integrase strand transfer inhibitors resistance mutations in people with virologically suppressed HIV infection.

Introduction: We assessed the kinetics of the clearance of integrase strand transfer inhibitors resistance mutations (INSTIs-RMs) and associated factors from people living with HIV (PWH) displaying suppressed viral replication after virological failure (VF) on an INSTI regimen.

Patients And Methods: We included PWH with HIV-RNA viral loads ≤20 copies/mL for at least 5 years in whom INSTIs-RM had been identified at least once in a prior RNA resistance genotyping test. HIV DNAs were sequenced by Sanger sequencing (SS) and ultra-deep sequencing (UDS; detection threshold: 5%) every year over the preceding 5 years.

Radiomic study of antenatal prediction of severe placenta accreta spectrum from MRI.

Objectives: We previously demonstrated the potential of radiomics for the prediction of severe histological placenta accreta spectrum (PAS) subtypes using T2-weighted MRI. We aim to validate our model using an additional dataset. Secondly, we explore whether the performance is improved using a new approach to develop a new multivariate radiomics model.

Modulation of neuroinflammation and oxidative stress by targeting GPR55 - new approaches in the treatment of psychiatric disorders.

Pharmacological treatment of psychiatric disorders remains challenging in clinical, pharmacological, and scientific practice. Even if many different substances are established for treating different psychiatric conditions, subgroups of patients show only small or no response to the treatment. The neuroinflammatory hypothesis of the genesis of psychiatric disorders might explain underlying mechanisms in these non-responders.
