Background: Non-adherence to highly active antiretroviral therapy (HAART) favours drug resistance and wastes resources. These have negative implications for personal and public health.
Objective: To assess adherence levels, the associated factors and its association with increase in CD4 cell count in people living with HIV (PLHIVs).
Methods: In a cross-sectional survey, systematically selected adult PLHIVs attending a tertiary hospital in Nigeria self-reported their 28-day adherence to HAART and reasons for missing doses using an interviewer-administered questionnaire. Their 6-month difference in CD4 cell count was also assessed.
Results: The participants totalled 425. Their mean age was 38.6 (SD, 10.1) years and 309 (72.7%) had secondary or tertiary education. The 28-day mean adherence level was 96.8% (SD, 7.9%) and 354 (83.3%) participants had optimal adherence (≥ 95%). Socio-demographic characteristics, side effects and having human reminders were not associated with adherence level, but 100% adherence level since placement on HAART was positively associated with a 6-month increase in CD4 cell count ( < 0.01; OR = 1.87, 95%CI = 1.21 - 2.89). Reasons given by 156 respondents for missing doses included being too busy, 100 (64.1%), forgetting, 85 (54.5%) and sleeping off, 42 (26.9%).
Conclusion: Mean adherence was high and the majority of participants had optimal adherence. "Never missing a dose" was associated with improved CD4 cell counts, indicating better prognosis. Socio-demographic factors, side effects and human reminders were not associated with an increase in adherence. However, as there is no evidence that adherence improvement measures are detrimental, their use is still recommended.

Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.

Our study aims to investigate the role of pyrimidine metabolism in prostate cancer and its associations with the immune microenvironment, drug sensitivity, and tumor mutation burden. Through transcriptomic and single-cell RNA sequencing analyses, we explored metabolic pathway enrichment, immune infiltration patterns, and differential gene expression in prostate cancer samples. The results showed that pyrimidine metabolism-related genes were significantly upregulated in the P2 subgroup compared to the P1 subgroup, with enhanced metabolic activity observed in basal and luminal epithelial cells.

Parkinson's disease (PD) is an age-related and progressive neurodegenerative disease. Growing evidences indicate that CD4 T cell dysfunction plays an essential role in the progress of PD. Here, in LPS-induced PD mice, we isolated midbrain CD4 T cell and peripheral CD4 T cell to perform proteomics, and then screened a total of 167 co-expression proteins via integrated bioinformatics analysis.

CD4FOXP3 regulatory T cells (T) suppress immune responses to tumors, and their accumulation in the tumor microenvironment (TME) correlates with poor clinical outcome in several cancers, including breast cancer (BC). However, the properties of intratumoral T remain largely unknown. Here, we found that a functionally distinct subpopulation of T, expressing the FOXP3 Exon2 splicing variants, is prominent in patients with hormone receptor-positive BC with poor prognosis.

Objective: To evaluate the impact of ART duration and CD4 count on risk for high grade cervical dysplasia in women with HIV (WWH) compared to women without HIV in the treat-all era with integrase strand inhibitors (INSTIs).
Design: Prospective longitudinal cohort study in Botswana.
Methods: From February 2021 to August 2022, baseline HPV self-sampling was offered to women with and without HIV.
