Changes in NNRTI use have not altered the ecology of NNRTI resistance over the last 10 years in people with HIV experiencing virological failure on antiretroviral drugs.

Background: We aimed to determine how non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance profiles have changed over the last decade in people living with HIV (PLWHIV) experiencing virological failure on all antiretroviral treatments, including different NNRTIs.

Materials And Methods: We analysed the use of the different NNRTIs in PLWHIV treated with antiretroviral drugs at an academic centre and the HIV NNRTI resistance profiles observed in cases of virological failure over the last 10 years (2014-23). We used the latest ANRS-MIE algorithm (v33; https://hivfrenchresistance.

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.

Assessment of land degradation susceptibility within the Shaqlawa subregion of Northern Iraq-Kurdistan Region via synergistic application of remotely acquired datasets and advanced predictive models.

Land degradation (LD) is the decline in a land's functional capacity and productive potential, which includes various anthropogenic and natural drivers. This study focuses on three primary manifestations of LD including soil erosion, landslides, and rockfalls, which are the most prevalent in the Shaqlawa district. A set of 22 LD conditioning factors, encompassing curvature, lithology, aspect, river density, soil type, lineament density, river distance, elevation, road distance, length slope (LS), land use land cover (LULC), stream power index (SPI), valley depth, profile curvature, slope, solar radiation, road density, lineament distance, rainfall, topographic wetness index (TWI), plan curvature, and normalized difference vegetation index (NDVI), were integrated into the analysis.

The RT M184V resistance mutation clearance in the reservoir is mainly related to CD4 nadir and viral load zenith independently of therapeutic regimen type.

Objectives: Resistance associated mutations (RAMs) are archived in the HIV reservoir and can re-emerge with an inappropriate ART use limiting treatment options. However, recent studies, using ultra-deep sequencing (UDS), showed a decrease of quasispecies harbouring RAMs, suggesting that recycling some antiretrovirals could be considered. The aim of this study was to characterize, in HIV treated PLWHIV, the M184V mutation decrease kinetics in proviral DNA and associated factors of M184V mutation clearance over time.

Pattern and determinants of contraceptive use among the muslim women in Wajir and Lamu counties in Kenya: a cross-sectional study.

Background: Improving access to family planning (FP) is associated with positive health benefits that includes averting nearly a third of all maternal deaths and 10% of childhood deaths. Kenya has made great strides in improving access to family planning services. However, amid this considerable progress, regional variation has been noted which begs the need for a clearer understanding of the the patterns and determinants that drive these inconsistencies.

The primary objective was to identify areas within the district that are prone to significant erosion and develop appropriate soil conservation schemes accordingly. A combination of primary and secondary data from diverse sources was utilized to achieve this objective.

Is vaccine response to SARS-CoV-2 preserved after switching to anti-CD20 therapies in patients with multiple sclerosis or related disorders?

Background: Although vaccination against SARS-CoV-2 is recommended prior to introducing anti-CD20 therapies, limited data are available regarding the evolution of post-vaccinal immunity.

Methods: This retrospective study compared anti-Spike antibody titres at 6 and 12 months from SARS-CoV-2 vaccination between patients vaccinated before switching to anti-CD20 ('Switch') and two control groups: (1) patients vaccinated under disease-modifying therapies (DMTs) other than fingolimod and anti-CD20 ('Other DMTs'); (2) patients vaccinated on anti-CD20 ('Anti-CD20'). Anti-Spike-specific T-cell responses were compared between 'Switch' and 'Anti-CD20' groups.

Doravirine plus lamivudine two-drug regimen as maintenance antiretroviral therapy in people living with HIV: a French observational study.

Background: Two-drug regimens based on integrase strand transfer inhibitors (INSTIs) and boosted PIs have entered recommended ART. However, INSTIs and boosted PIs may not be suitable for all patients. We aimed to report our experience with doravirine/lamivudine as maintenance therapy in people living with HIV (PLWH) followed in French HIV settings.

Prevalence of Multidrug-Resistant TB Among Smear-Positive Pulmonary TB Patients in Banadir, Somalia: A Multicenter Study.

Background: Tuberculosis (TB) is an infectious disease that is the second most common cause of death from a single infectious agent. TB infection affects anyone, regardless of age, gender, and ethnicity. Drug-resistant TB is a serious public health problem, which needs treatment with a second-line anti-TB drug and it includes poly-drug resistance (PDR), multi-drug resistance (MDR), and extensive drug resistance (XDR).

Viral suppression and HIV-1 drug resistance 1 year after pragmatic transitioning to dolutegravir first-line therapy in Malawi: a prospective cohort study.

Background: Many countries are now replacing non-nucleoside reverse transcriptase inhibitor (NNRTI)-based first-line antiretroviral therapy (ART) with a regimen containing tenofovir disoproxil fumarate, lamivudine, and dolutegravir (TLD). Recognising laboratory limitations, Malawi opted to transition those on NNRTI-based first-line ART to TLD without viral load testing. We aimed to assess viral load and HIV drug resistance during 1 year following transition to TLD without previous viral load testing.

Influence of Raster Pattern on Residual Stress and Part Distortion in FDM of Semi-Crystalline Polymers: A Simulation Study.

In fused deposition modelling (FDM) based on the selected raster pattern, the developed internal thermal residual stresses can vary considerably affecting the mechanical properties and leading to distinct part distortions. This phenomenon is more pronounced in semi-crystalline than amorphous polymers due to crystallisation. Hence, this study focuses on the simulation of the FDM process of a semi-crystalline polymer (polypropylene) with raster patterns such as line (90°/90°), line (0°/90°), zigzag (45°/45°), zigzag (45°/-45°), and concentric from Cura (slicing software).
