Background: Host genetic variation influences human immunodeficiency virus (HIV) infection and progression to AIDS. Here we used clinically well-characterized subjects from 5 pretreatment HIV/AIDS cohorts for a genome-wide association study to identify gene associations with rate of AIDS progression.
Methods: European American HIV seroconverters (n = 755) were interrogated for single-nucleotide polymorphisms (SNPs) (n = 700,022) associated with progression to AIDS 1987 (Cox proportional hazards regression analysis, co-dominant model).
Results: Association with slower progression was observed for SNPs in the gene PARD3B. One of these, rs11884476, reached genome-wide significance (relative hazard = 0.3; P =3. 370 × 10(-9)) after statistical correction for 700,022 SNPs and contributes 4.52% of the overall variance in AIDS progression in this study. Nine of the top-ranked SNPs define a PARD3B haplotype that also displays significant association with progression to AIDS (hazard ratio, 0.3; P = 3.220 × 10(-8)). One of these SNPs, rs10185378, is a predicted exonic splicing enhancer; significant alteration in the expression profile of PARD3B splicing transcripts was observed in B cell lines with alternate rs10185378 genotypes. This SNP was typed in European cohorts of rapid progressors and was found to be protective for AIDS 1993 definition (odds ratio, 0.43, P = .025).
Conclusions: These observations suggest a potential unsuspected pathway of host genetic influence on the dynamics of AIDS progression.

Triple-negative breast cancer (TNBC) presents a formidable therapeutic challenge due to its aggressive behavior, molecular heterogeneity, and lack of actionable targets. This study identifies activation-induced cytidine deaminase (AID) as a pivotal epigenetic driver reprogramming the tumor microenvironment (TME) via non-canonical regulation of NOTCH signaling. Mechanistically, AID recruits histone acetyltransferase 1 (HAT1) to form a chromatin-remodeling complex that binds the JAG1 promoter region (-1.

Background: In recent years, social media has emerged as a pivotal tool in implementation science efforts to address the HIV epidemic. Engaging community partners is essential to ensure the successful and equitable implementation of social media strategies. There is a notable lack of scholarship addressing the operational considerations for studies using social media strategies in community-partnered HIV research.

Tony Kushner's Angels in America, written in two parts during the early 1990s, vividly depicts the experiences of queer individuals confronting the AIDS crisis. Examined through the framework of anocriticism and queer temporality, the play challenges traditional life trajectories focused on reproduction, aging, and progress. Drawing on the work of theorists such as Roberta Maierhofer, Jack Halberstam, and Elizabeth Freeman, this analysis investigates how the play's fragmented narrative and interplay of supernatural and historical elements blur the boundaries between past, present, and future.

Background: Despite advances in HIV care, viral load suppression (VLS) among adolescents living with HIV (ALHIV) in Uganda continue to lag behind that of adults, even with the introduction of dolutegravir (DTG)-based regimens, the Youth and Adolescent Peer Supporter (YAPS) model, and community-based approaches. Understanding factors associated with HIV viral load non-suppression in this population is critical to inform HIV treatment policy. This study assessed the prevalence and predictors of viral load non-suppression among ALHIV aged 10-19 years on DTG-based ART in Soroti City, Uganda.

Purpose: Patients with Alzheimer's disease (AD) lose the ability to manage their medications as the disease progresses. Several methods have been used to administer medication to patients at home using Internet of Things (IoT) devices for rehabilitation, but no studies have yet been published investigating the factors that influence the success or failure of this approach in older adults and patients with AD. Therefore, this study aimed to investigate differences in medication-related behaviors and their influencing factors in older adults, both with and without AD, using IoT.
