Introduction: Antiretroviral therapy (ART) initiation in infants living with HIV before 12 weeks of age can reduce the risk of mortality by 75%. Point‐of‐care (POC) diagnostic testing is critical for prompt ART initiation; however, despite its availability, rates of ART initiation are still relatively low before 12 weeks of age. This systematic review describes the barriers to ART initiation in infants before 12 weeks of age, despite the availability of POC. Methods: This systematic review used a narrative synthesis methodology. We searched PubMed and Scopus using search strategies that combined terms of multiple variants of the keywords "early infant initiation on antiretroviral therapy," "barriers" and "sub‐Saharan Africa" (initial search 18th January 2023; final search 1st August 2023). We included qualitative, observational and mixed methods studies that reported the influences of early infant initiation on ART. We excluded studies that reported influences on other components of the Prevention of Mother to Child Transmission cascade. Using a deductive approach guided by the updated Consolidated Framework of Implementation Research, we developed descriptive codes and themes around barriers to early infant initiation on ART. We then developed recommendations for interventions for the identified barriers using the action, actor, target and time framework from the codes. Results: Of the 266 abstracts reviewed, 52 full‐text papers were examined, of which 12 papers were included. South Africa had most papers from a single country (n = 3) and the most reported study design was retrospective (n = 6). Delays in ART initiation beyond 12 weeks in infants 0–12 months were primarily associated with health facility and maternal factors. The most prominent barriers identified were inadequate resources for POC testing (including human resources, laboratory facilities and patient follow‐up). Maternal‐related factors, such as limited male involvement and maternal perceptions of treatment and care, were also influential. Discussion: We identified structural barriers to ART initiation at the health system, social and cultural levels. Improvements in the timely allocation of resources for POC testing operations, coupled with interventions addressing social and behavioural barriers among both mothers and healthcare providers, hold a promise for enhancing timely ART initiation in infants. Conclusions: This paper identifies barriers and proposes strategies for timely ART initiation in infants. [ABSTRACT FROM AUTHOR]

This document discusses a special issue on wildlife viruses and their impact on human and animal health. It highlights the increasing threat of new viral infectious diseases among wildlife populations, which can spill over into human hosts due to ecological, demographic, and socioeconomic changes. The document includes four research papers that delve into specific topics related to wildlife viruses. These topics include the genetic diversity and evolutionary trajectories of avian adenoviruses, the presence and genetic characterization of canine distemper virus in Crab-eating foxes, West Nile virus and Usutu virus surveillance in avian species, and the structural and biochemical interactions between the capsid protein of porcine adeno-associated virus and the nuclear trafficking protein importin alpha. The research papers provide valuable insights into the diversity, transmission patterns, and potential risks of viral pathogens in wildlife, emphasizing the need for continuous surveillance, molecular studies, and interdisciplinary approaches to managing public health risks associated with these viruses.

ORPHANS ,AIDS ,SOCIAL services ,HIV ,RESEARCH personnel ,SOCIAL stigma - Abstract
A recent study conducted by researchers from Makerere University in Uganda explores the role of social work and faith-based communities in combating HIV-related stigma. The researchers emphasize that stigma is a major factor contributing to the spread of HIV and AIDS and argue that integrating social work skills and knowledge with religious organizations and communities can help address this issue. They highlight the importance of political actions, religious influence, societal engagement, social dynamics, and openness in combating stigma and assisting prevention efforts. The researchers also emphasize the role of religious leaders in using their authority and trust within their communities to make a significant impact on the HIV and AIDS epidemic. They suggest that engaging community members and church leaders can contribute to effective program planning and development resources to address stigma. The study concludes by encouraging social workers to focus on the formation of support groups, faith-based peer education, counseling, and support services to provide social, emotional, and spiritual support to individuals affected by HIV and AIDS and associated stigma.

HIV ,AIDS ,INFECTIOUS disease transmission - Abstract
Objective: To end the AIDS epidemic by 2030, despite the increasing poverty and inequalities, policies should be designed to deal with population heterogeneity and environmental changes. Bottom-up designs, such as the Agent-Based Model (ABM), can model these features, dealing with such complexity. HIV/AIDS has a complex dynamic of structural factors, risk behaviors, biomedical characteristics and interventions. All embedded in unequal, stigmatized and heterogeneous social structure. To understand how ABMs can model this complexity, we performed a scoping review of HIV applications, highlighting their potentialities. Methods: We searched on PubMed, Web of Science, and Scopus repositories following the PRISMA extension for scoping reviews. Our inclusion criteria were HIV/AIDS studies with an ABM application. We identified the main articles using a local co-citation analysis and categorized the overall literature aims, (sub)populations, regions, and if the papers declared the use of ODD protocol and limitations. Results: We found 154 articles. We identified eleven main papers, and discussed them using the overall category results. Most studies model Transmission Dynamics (37/154), about Men who have sex with Men (MSM) (41/154), or individuals living in the US or South Africa (84/154). Recent studies applied ABM to model PrEP interventions (17/154) and Racial Disparities (12/154). Only six papers declared the use of ODD Protocol (6/154), and 34/154 didn't mention the study limitations. Conclusions: While ABM is among the most sophisticated techniques available to model HIV/AIDS complexity. Their applications are still restricted to some realities. However, researchers are challenged to think about social structure due model characteristics, the inclusion of these features is still restricted to case-specific. Data and computational power availability can enhance this feature providing insightful results. [ABSTRACT FROM AUTHOR]

ECOLOGICAL momentary assessments (Clinical psychology) ,CHRONIC pain ,HIV-positive persons ,ALCOHOL drinking ,RANDOMIZED controlled trials - Abstract
Background: Unhealthy alcohol use represents a significant risk for morbidity and mortality among people living with HIV (PLWH), in part through its impact on HIV management. Chronic pain, a common comorbidity, exacerbates suboptimal engagement in the HIV care continuum and has reciprocal detrimental effects on alcohol outcomes. There are no integrated, accessible approaches that address these comorbid conditions among PLWH to date. This paper describes a research study protocol of an integrated telehealth intervention to reduce unhealthy drinking and chronic pain among PLWH (Motivational and Cognitive-Behavioral Management for Alcohol and Pain [INTV]). Methods: Two-hundred and fifty PLWH with unhealthy drinking and chronic pain will be recruited nationally via online advertisement. Informed consent and baseline assessments occur remotely, followed by 15 days of ecological momentary assessment to assess alcohol use, chronic pain, functioning, and mechanisms of behavior change. Next, participants will be randomized to either the INTV or Control (CTL) condition. Individuals in both conditions will meet with a health counselor through videoconferencing following randomization, and those in the INTV condition will receive 6 additional sessions. At 3- and 6-months post-baseline, participants will complete outcome assessments. It is hypothesized that the INTV condition will result in reduced unhealthy alcohol use and pain ratings compared to the CTL condition. Conclusion: This protocol paper describes a randomized controlled trial which tests the efficacy of a novel, integrated telehealth approach to reduce unhealthy alcohol use and chronic pain for PLWH, two common comorbid conditions that influence the HIV treatment cascade. ClinicalTrials.gov identifier: NCT05503173. Highlights: Unhealthy alcohol use and chronic pain are common in people living with HIV. An integrated telehealth intervention may improve alcohol, pain, and HIV outcomes. Ecological momentary assessment will examine processes underlying behavior change. [ABSTRACT FROM AUTHOR]

The need for new drugs to treat human infections is a global health concern. Diseases like tuberculosis, trypanosomiasis, amoebiasis, and AIDS remain significant problems, especially in developing countries like Mexico. Despite existing treatments, issues such as resistance and adverse effects drive the search for new alternatives. Herein, we introduce the NUATEI research consortium, made up of experts from the Institute of Biomedical Research at UNAM, who identify and obtain natural and synthetic compounds and test their effects against human pathogens using in vitro and in vivo models. The consortium has evaluated hundreds of natural extracts and compounds against the pathogens causing tuberculosis, trypanosomiasis, amoebiasis, and AIDS, rendering promising results, including a patent with potential for preclinical studies. This paper presents the rationale behind the formation of this consortium, as well as its objectives and strategies, emphasizing the importance of natural and synthetic products as sources of antimicrobial compounds and the relevance of the diseases studied. Finally, we briefly describe the methods of the evaluation of the compounds in each biological model and the main achievements. The potential of the consortium to screen numerous compounds and identify new therapeutic agents is highlighted, demonstrating its significant contribution to addressing these infectious diseases.

Introduction: Implementation science (IS) offers methods to systematically achieve the Ending the HIV Epidemic goals in the United States, as well as the global UNAIDS targets. Federal funders such as the National Institutes of Mental Health (NIMH) have invested in implementation research to achieve these goals, including supporting the AIDS Research Centres (ARCs), which focus on high‐impact science in HIV and mental health (MH). To facilitate capacity building for the HIV/MH research workforce in IS, "grey areas," or areas of IS that are confusing, particularly for new investigators, should be addressed in the context of HIV/MH research. Discussion: A group of IS experts affiliated with NIMH‐funded ARCs convened to identify common and challenging grey areas. The group generated a preliminary list of 19 grey areas in HIV/MH‐related IS. From the list, the authors developed a survey which was distributed to all ARCs to prioritize grey areas to address in this paper. ARC members across the United States (N = 60) identified priority grey areas requiring clarification. This commentary discusses topics with 40% or more endorsement. The top grey areas that ARC members identified were: (1) Differentiating implementation strategies from interventions; (2) Determining when an intervention has sufficient evidence for adaptation; (3) Integrating recipient perspectives into HIV/MH implementation research; (4) Evaluating whether an implementation strategy is evidence‐based; (5) Identifying rigorous approaches for evaluating the impact of implementation strategies in the absence of a control group or randomization; and (6) Addressing innovation in HIV/MH IS grants. The commentary addresses each grey area by drawing from the existing literature (when available), providing expert guidance on addressing each in the context of HIV/MH research, and providing domestic and global HIV and HIV/MH case examples that address these grey areas. Conclusions: HIV/MH IS is key to achieving domestic and international goals for ending HIV transmission and mitigating its impact. Guidance offered in this paper can help to overcome challenges to rigorous and high‐impact HIV/MH implementation research. [ABSTRACT FROM AUTHOR]

There is a growing population of adults aged 50 years or older living with HIV, facing unique challenges in care due to age, minority status, and stigma. Co-design methodologies, aligning with patient-centered care, have potential for informing interventions addressing the complex needs of older adults with HIV. Despite challenges, co-design has shown promise in empowering older individuals to actively participate in shaping their care experiences. The scoping review outlined here aims to identify gaps in existing co-design work with this population, emphasizing the importance of inclusivity based on PROGRESS-Plus characteristics for future patient-oriented research. This scoping review protocol is informed by the Joanna Briggs Institute Manual to explore co-design methods in geriatric HIV care literature. The methodology encompasses six stages: 1) developing research questions, 2) creating a search strategy, 3) screening and selecting evidence, 4) data extraction, 5) data analysis using content analysis, and 6) consultation with key stakeholders, including community partners and individuals with lived experience. The review will involve a comprehensive literature search, including peer-reviewed databases and gray literature, to identify relevant studies conducted in the past 20 years. The inclusive criteria focus on empirical data related to co-design methods in HIV care for individuals aged 50 or older, aiming to inform future research and co-design studies in geriatric HIV care. The study will be limited by the exclusion of papers not published or translated to English. Additionally, the varied terminology used to describe co-design across different research may result in the exclusion of articles using alternative terms. The consultation with key stakeholders will be crucial for translating insights into meaningful co-design solutions for virtual HIV care, aiming to provide a comprehensive synthesis that informs evidence-based strategies and addresses disparities in geriatric HIV care.

Purpose: This paper aims to describe the unique health challenges facing female commercial sex workers (FSWs), including issues related to their marginalisation and difficulty accessing health care. It proposes solutions to some of these problems. Design/methodology/approach: This paper addresses this sensitive subject through the methodology of a literature review, drawing on a variety of relevant published literature to inform a modern understanding of the current health challenges faced by this population. Findings: This paper discusses issues around criminalisation of commercial sex workers, complexities of family planning, sexually transmitted infection prevention, mental health and substance abuse and how increasing health-care worker awareness of the health needs of this vulnerable population can be a positive step in building trust within this relationship. Although adoption of the proposed recommendations put forth in this paper may help to eliminate some of the barriers encountered by female sex workers, further research is recommended. Originality/value: The subject of commercial sex worker health care is neglected in the academic literature. This review explores the topic in an open and balanced manner and presents a broad and updated overview of the current health-care challenges faced by FSWs as well as opportunities for optimising access and quality of sex worker health care.

Thirty-eight years into the HIV and AIDS pandemic, the world is still striving to reduce global HIV infections towards zero new infections and AIDS-related deaths by 2030. Sub-Saharan Africa continues to carry the burden of global HIV infections as governmental and nongovernmental agencies try out different prevention strategies (UNAIDS, 2024b). Several scholars have argued that comprehensive sexuality education (CSE) is the best preventive strategy to reach youth and key populations with factual information regarding HIV and AIDS. This paper draws from the project, Mentoring as a Method to Promote Women's Health in the Context of HIV-Prevention and Unequal Gender Relations, which employed memory work, photo-voice, drama, drawings, and focus group discussions with third-year student teachers in a life orientation module. Focussing on the data generated through drama, I present an arts-based activity that was used to teach about HIV transmission to student teachers in a bid to equip them with alternative ways of teaching school-learners about HIV and AIDS. The findings highlight student teachers' lived experiences and how they have shaped their perceptions of HIV infections and living with AIDS. I argue from the findings, that arts-based pedagogies allow for enhanced understanding of complex phenomena due to their participatory and in-built intervention nature. Thus, I posit that pedagogies that employ participatory, arts-based, and visual methodologies should be extensively employed in teacher-education towards reducing new HIV infections among the youth.

- Abstract
Background: In Peru, HIV cases are highly concentrated among men who have sex with men (MSM). Despite the availability of anti-retroviral therapy, people living with HIV (PWH) have higher levels of oral diseases. Alcohol use disorder (AUD) is significantly present among PWH. Our overarching goal was to generate foundational evidence on the association of AUD and oral health in MSM with HIV and enhance research capacity for future intersectional research on AUD, oral health and HIV. Our specific aim was to implement an on-site electronic data collection system through the use of a REDCap Mobile App in a low-middle income country (LMIC) setting. Methods: Five validated surveys were utilized to gather data on demographics, medical history, HIV status, alcohol use, HIV stigma, perceived oral health status, and dietary supplement use. These surveys were developed in REDCap and deployed with the REDCap Mobile App, which was installed on ten iPads across two medical HIV clinics in Lima, Peru. REDCap app as well as the protocol for data collection were calibrated with feedback from trial participants and clinical research staff to improve clinical efficiency and participant experience. Results: The mean age of participants (n = 398) was 35.94 ± 9.13y, of which 98.5% identified as male, and 85.7% identified as homosexual. 78.1% of participants binge drank, and 12.3% reported being heavy drinkers. After pilot testing, significant modifications to the structure and layout of the surveys were performed to improve efficiency and flow. The app was successfully deployed to replace cumbersome paper records and collected data was directly stored in a REDCap database. Conclusions: The REDCap Mobile App was successfully used due to its ability to: (a) capture and store data offline, (b) timely translate between multiple languages on the mobile app interface, and (c) provide user-friendly interface with low associated costs and ample support.

Background. People living with HIV continue to face laws, policies, and practices that impact their potential for travel and migration. These laws include: mandatory HIV testing and involuntary disclosure of HIV; lack of access to affordable HIV-related health care, treatment and counselling during the migration process; deportation of foreign nationals living with HIV; and restrictions on the length of stays. Methods. HIV migration laws were the topic of a half-day community forum held as part of the 12th International AIDS Society Conference on HIV Science held in Brisbane, Australia, in July 2023. Over 150 delegates attended and, after a series of presentations, delegates were invited to participate in structured, facilitated conversations about issues related to policy, health and law concerning migration of people living with HIV. In this paper, we report on key themes from those discussions and identify areas for ongoing investigation. Results. Advocates recommended the removal of unfair and unjust migration laws and policies that contribute to HIV stigma and discrimination; updated migration policies that reflect the current context and cost of biomedical approaches to HIV management and prevention; expanded and equitable access to HIV-related care regardless of migration or residency status; and the development of advocacy networks to promote changes to migration policies. Conclusions. Laws limiting the migration of people living with HIV actively discourage individuals from seeking HIV testing, treatment and care. Ultimately, restrictive migration laws and policies undermine global efforts to end AIDS as a public health concern and to virtually eliminate HIV transmission by 2030. [ABSTRACT FROM AUTHOR]

In this article, a reaction–diffusion model of HIV immunity with chemotaxis and absorption effect is constructed. The paper proves the existence and boundedness of the global classical solution of this mode when the chemotactic coefficient is kept in a suitable range. Five equilibrium points are established based on the different ranges of the basic regeneration number, two immune reproduction numbers and the immune competitive reproduction number. The global asymptotic stability of each equilibrium point is established by constructing an appropriate Lyapunov function when the chemotactic coefficient is kept in a small interval.

Background: The United Nations' 95-95-95 (95% of people with HIV being aware of their diagnosis, 95% of those aware of their diagnosis being on treatment and 95% achieving viral suppression) target aims to reduce morbidity and mortality of HIV. However, with 60% of new HIV infections occurring in sub-Saharan Africa (SSA), achieving this target in the region is challenging. Viral load (VL) monitoring is the gold-standard approach of assessing treatment efficacy, and its implementation into national health systems is a global health priority if elimination of HIV as a public health threat is to be achieved by 2030. This systematic review aims to investigate VL monitoring outcomes in SSA, and to identify gaps and possible interventions to help nations meet their 2030 targets. Methods: A literature search of three electronic platforms (MEDLINE, EMBASE and Global Health) was undertaken from 1 January to 9 August 2024 to identify studies published in English and conducted in SSA. The primary outcome was the proportion of people living with HIV (PLHIV) on antiretroviral therapy (ART) with routine VL monitoring at the recommended time points (initially, 6 months, 12 months and annually). Secondary outcomes reported proportions of PLHIV who received routine VL monitoring who went on to complete the cascade of care after identified virological failure [enhanced adherence counselling (EAC), switch to second-line ART, and finally viral suppression]. Results: The initial search identified 342 papers, of which 35 studies were included for narrative synthesis. Included studies reported on findings from 14 African countries and demonstrated extensive variation in rates of VL monitoring (range: 24.3-99.7%, mean: 63.8%). Results were more unfavourable in the latter steps of the viral load monitoring cascade, with a range of 0-88%, and a switch to second-line ART mean of 42% (range: 4.4-93%). Studies with additional support, and those with community-based models of care, had higher rates of VL testing and viral suppression. Conclusions: VL monitoring and management of virological failure are suboptimal in many SSA countries due to individual and health system-related challenges. Health system strengthening is vital to ensure the sustainability of HIV treatment programmes and the achievement of 95-95-95 targets by 2030. [ABSTRACT FROM AUTHOR]

Background: Suicide is one of the main causes of mortality in the world, accounting for more fatalities than homicide, war, human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), breast cancer, and malaria. Significantly, the biggest risk factors for suicide in the general population are having already attempted suicide and suicidal ideation. Despite the availability of studies on suicidal ideation among people living with HIV/AIDS (PLWHA) in Ethiopia, the results are inconsistent. Thus, a systematic review and meta-analysis was conducted to estimate the pooled prevalence of suicidal ideation among people living with HIV/AIDS. Methods: A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. To find papers published in the English language before 20 May 2023, the electronic databases of Medline, Science Direct, Excerpta Medica Database, Cochrane Library, African Journals Online (AJOL), and Google Scholar were searched. The DerSimonian and Laird method for random effects models was used to estimate the pooled prevalence of suicidal ideation with a 95% confidence interval in STATA V.14.0 statistical software. To test for heterogeneity between studies and publication bias, respectively, forest plots and funnel plots were used. Additionally, leave-one-out sensitivity was conducted. Results: A total of nine studies with 3,411 study participants were included in this systematic review and meta-analysis. The pooled prevalence of suicidal ideation among PLWHA was 20.55% (95% CI 14.76, 26.33). Being female (Odds ratio (OR) = 4.27, 95% CI = 2.29, 7.97), living alone (OR = 5.02, 95% CI = 2.15, 11.64), poor social support (OR = 3.80, 95% CI = 2.56, 5.65), perceived stigma (OR = 3.50, 95% CI = 1.55, 7.87), depression (OR = 5.08, 95% CI = 2.55, 11.48), undisclosed HIV status (OR = 4.8, 95% CI = 2.10, 10.93), and World Health Organization HIV clinical stages of III or IV (OR = 4.40, 95% CI = 2.95, 6.58) were significantly associated with suicidal ideation. Conclusion: Suicidal ideation among PLWHA is high in Ethiopia. Therefore, emphasis should be given to psychiatric assessment and interventions with a special focus on individuals having the associated factors. [ABSTRACT FROM AUTHOR]

Despite treatment and other interventions, an effective prophylactic HIV vaccine is still an essential goal in the control of HIV. Inducing robust and long-lasting antibody responses is one of the main targets of an HIV vaccine. The delivery of HIV envelope glycoproteins (Env) using nanoparticle (NP) platforms has been shown to elicit better immunogenicity than soluble HIV Env. In this paper, we describe the development of a nanoparticle-based vaccine decorated with HIV Env using the SpyCatcher/SpyTag system. The Env utilised in this study, CAP255, was derived from a transmitted founder virus isolated from a patient who developed broadly neutralising antibodies. Negative stain and cryo-electron microscopy analyses confirmed the assembly and stability of the mi3 into uniform icosahedral NPs surrounded by regularly spaced CAP255 gp140 Env trimers. A three-dimensional reconstruction of CAP255 gp140 SpyTag–SpyCatcher mi3 clearly showed Env trimers projecting from the centre of each of the pentagonal dodecahedral faces of the NP. To our knowledge, this is the first study to report the formation of SpyCatcher pentamers on the dodecahedral faces of mi3 NPs. To investigate the immunogenicity, rabbits were primed with two doses of DNA vaccines expressing the CAP255 gp150 and a mosaic subtype C Gag and boosted with three doses of the NP-developed autologous Tier 2 CAP255 neutralising antibodies (Nabs) and low levels of heterologous CAP256SU NAbs.

- Abstract
The aim of this systematic review and meta‐analysis was to comprehensively evaluate the latest evidences and summarise the impact of HIV on PCI outcomes. A PRISMA guided literature search was conducted on 14 February 2024 in Web of Science, PubMed, Virtual Health Library, Google Scholar and Scopus. We searched with the term '("percutaneous coronary intervention" OR "PCI") AND ("human immunodeficiency virus" OR "HIV" OR "acquired immunodeficiency syndrome" OR "AIDS")' after selecting the keywords from randomly chosen included papers. We included 8 papers of 781 screened records. HIV (+) patients had significant in‐hospital, 1‐year and overall (event at the last follow up point) all‐cause mortality compared to HIV (−) group (OR: 1.73, 95%CI: 1.57–1.90, p < 0.01), (OR: 1.39, 95%CI: 1.07–1.81, p = 0.01) and (OR: 1.69, 95%CI: 1.55–1.85, p < 0.01), respectively. HIV (+) patients had significantly higher odds of developing MACE (OR: 1.35, 95%CI: 1.12–1.62, p = 0.001) compared to the HIV (−) group. No differences between both groups were detected regarding in‐hospital and overall CV mortality, TVR, TLR, post‐PCI TIMI grade 3 flow, cerebrovascular accidents and recurrent coronary events (p > 0.05). Our study revealed that people with HIV who underwent PCI in this modern era may have worse short and long‐term PCI outcomes. This finding highlights the need for specialised cardiovascular care protocols for the HIV population. However, enhanced clinical management and preventative measures are imperative to improve PCI success rates in patients with HIV. [ABSTRACT FROM AUTHOR]

Introduction: Vertical transmission of HIV remains a major challenge in Guinea, especially, in low-resource rural areas. This paper presents the results of a pilot project designed to enhance the prevention of vertical transmission through a comprehensive improvement plan implemented across 66 large-cohort sites. Methods: Data from 66 large-cohort of mother to child transmission prevention (PMTCT) sites from 2019 to 2022 were analysed to compare PMTCT metrics before (2019–2020) and after (2021–2022) the improvement initiative. Key indicators were reviewed, and trends were statistically analysed using Mann‒Whitney tests, with a p value less than 0.05 indicating statistical significance. Results: The implementation of this strategy significantly increased the antiretroviral therapy rate among HIV-positive pregnant women from 66 to 94%, and full antiretroviral prophylaxis coverage was achieved in infants. However, early infant diagnosis via polymerase chain reaction testing falls short of the national target, highlighting deficiencies in laboratory and specimen transport capacities. The study also revealed regional disparities in the use of PMTCT services. Conclusion: The improvement plan effectively enhanced antiretroviral therapy and prophylaxis use, demonstrating the benefits of structured interventions and capacity development. Despite improvements, challenges such as insufficient polymerase chain reaction (PCR) testing and uneven access to services remain. Future initiatives should aim to equip PMTCT sites with essential resources and promote community-driven health-seeking behaviours in underserved areas. [ABSTRACT FROM AUTHOR]

Occupational exposures in the large industrial mining sector contributed significantly to South Africa's high excess death rate due to COVID-19. Historically poor work-protection oversight has perpetuated centuries of risky labor and living conditions within the industry, driving high levels of disease co-morbidities, and supporting enduring social vulnerabilities. In this paper, we offer a syndemic lens to consider the clustering of adversely interacting diseases among mineworkers in South Africa, drawing attention to the complex occupational health crisis and the need to move beyond simply reporting individual diseases or comorbidities among this population. The physically demanding and dangerous working conditions, the lack of adequate changes to crowded and unsanitary working and living situations, the failure to meet social and labor plan targets, the continued precarious nature of working contracts and mines, and the limited access to robust healthcare reflect the historically exploitative nature of industrial mining in South Africa that places miners at increased risk for various syndemics. This assessment of the adverse interactions of diseases and socioeconomic and political conditions highlights the need for focused research and more follow-through in comprehensive occupational reforms.

Background: Attaining a good quality of life (QOL) is a priority for people living with HIV (PLHIV). We explored the interaction between QOL and the associated demographic, behavioural and clinical factors for PLHIV attending an outer-metropolitan clinical setting in Western Sydney, Australia. The clinic's cohort of PLHIV is characterised by relatively high proportions of women, heterosexual men, and patients from culturally and linguistically diverse (CALD) communities. Methods: We assessed QOL using the PozQol tool that is specifically designed for PLHIV. QOL scores and de-identified socio-demographic and clinical data were extracted from the electronic and paper medical records of PLHIV who completed a PozQol tool (September 2020–March 2022). We performed descriptive analyses and logistic regression to identify associations. Results: Among 188 patients, there were 77.7% men, 21.3% women, 1.1% transwomen; 67.0% were born overseas, 85.1% spoke English, 84.4% were Medicare-eligible, 85.9% were employed, 58.5% were diagnosed with HIV 6–20 years ago, and 33.0% within the past 5 years. Overall, 58.0% had a high or very high QOL. A low score in any domain was associated with Medicare-ineligibility. Low QOL scores in specific domains were associated with the following factors: health (being born overseas, having partners of both sexes), psychological (unemployment, having a mental health condition, having a viral load >20 copies/mL), social (unemployment), and functional (Medicare-eligibility, unemployment, having a viral load >20 copies/mL). Conclusions: The PozQol tool has enhanced understanding of factors impacting on QOL for PLHIV attending our service in Western Sydney. Identifying patients with low QOL scores allows targeted clinical interventions to improve QOL, and re-alignment of clinical services to better support PLHIV. Quality of life (QOL) is an important priority for people living with HIV (PLHIV). Using a patient-reported outcome measure (PozQol tool), we found that 58% of PLHIV reported a high or very high QOL, and socio-demographic factors such as Medicare-ineligibility and unemployment were associated with lower QOL scores. PozQol may assist services by enhancing understanding of QOL among PLHIV, guide local and national policy, health service provision, and promote empowerment of individuals to better understand their own QOL.

Long-acting injectable PrEP, particularly cabotegravir (CAB-LA), has the potential to enhance HIV prevention in Asia, and was the topic of a roundtable held in Singapore in June 2023. Despite proven efficacy, CAB-LA's impact in Asia is hindered by regulatory, manufacturing, and cost barriers. There is an urgent need to address these challenges to expedite CAB-LA's introduction and scale-up, including collaborative research, streamlined regulatory processes, and increased manufacturing capacity. We call for better preparedness in long-acting PrEP in research and implementation science, product licensing and accessibility, and capacity readiness for scale-up, to meet the significant demand among key populations in Asia. In June 2023, a roundtable of experts and stakeholders was held in Singapore focusing on the introduction of long-acting formulations of HIV pre-exposure prophylaxis in Asia, particularly long-acting injectable cabotegravir. This paper describes issues discussed at the roundtable related to preparedness in research and implementation science, product licensing and accessibility, and capacity readiness for scale-up of long-acting injectable pre-exposure prophylaxis and future pre-exposure prophylaxis products.

Objective: Several cases of Fanconi syndrome (FS), a severe form of nephrotoxicity, have been reported in patients with HIV on tenofovir-containing antiretroviral therapy. A systematic review of the published literature on tenofovir-related FS in patients with HIV was conducted. Data Sources: PubMed and Embase were queried to identify articles in English published between January 2005 and June 2023, reporting tenofovir-related FS in adults with HIV. Preclinical studies, conference/poster abstracts, commentaries and responses, and review papers were excluded. Study Selection and Data Extraction: Of the 256 articles screened, 57 met the inclusion criteria. These comprised 37 case reports, 11 case series, 1 cross-sectional study, 1 case-control study, 4 cohort studies, 1 single-arm open-label clinical trial, 1 sub-analysis of clinical trials, and 1 pooled analysis of clinical trials. Data Synthesis: Among 56 cases on which information was abstracted, median age at FS diagnosis was 50 years, 51.8% were men, and duration of tenofovir use ranged from 6 weeks to 11 years. Ritonavir was co-prescribed in almost half the cases. In observational and interventional studies, incidence of FS was low. Many studies reported resolution of FS symptoms after tenofovir discontinuation. All FS occurrences were identified in those on tenofovir disoproxil fumarate (TDF), except for one patient on tenofovir alafenamide (TAF). Relevance to Patient Care and Clinical Practice: Continuous monitoring of signs and symptoms of renal and bone toxicity is essential for patients with HIV on tenofovir-containing therapy. Conclusions: Occurrence of FS is low in patients with HIV treated with tenofovir-based regimens. Concomitant use of ritonavir may increase risk of FS. TAF may be a safer alternative than TDF in terms of nephrotoxicity. [ABSTRACT FROM AUTHOR]

Background: Safer conception services are needed to minimize HIV transmission among HIV sero-discordant couples desiring pregnancy. Few studies have evaluated the choices couples make when they are offered multiple safer conception methods or real-world method acceptability. This paper addresses an important knowledge gap regarding factors that influence the choice of safer conception methods, couples' actual experiences using safer conception methods, and why some couples switch safer conception methods. Methods: Between February and June 2019, we conducted semi-structured in-depth interviews among 14 men and 17 women, representing 17 couples who exited the SAFER study—a pilot safer conception study for HIV sero-discordant couples in Zimbabwe that offered couples a choice of ART with monthly viral load monitoring (ART/VL), oral PrEP, vaginal insemination, and semen washing. All couples in SAFER had used at least two safer conception methods. Results: We found that safer conception method choice often centered around a desire for intimacy, condomless sex, and certainty in the conception process, particularly for men. Method-related attributes such as familiarity, perceived ease of use, side effects, and perceived level of effectiveness in preventing HIV and achieving pregnancy influenced method choice, switching, and satisfaction. Concerns were expressed about each safer conception method and couples were willing to try different methods until they found method(s) that worked for them. The majority of participants reported having positive experiences using safer conception, especially those using ART/VL + PrEP, citing that they were able to attempt pregnancy for the first time with peace of mind and experienced joy and satisfaction from being able to achieve pregnancy safely. Conclusions: The differences in method preferences and experiences voiced by participants in this study and in other studies from the region point to the importance of having a variety of safer conception options in the service delivery package and addressing concerns about paternity, intimacy, and method-related attributes to enable HIV sero-discordant couples to safely achieve their reproductive goals.

Introduction: Kazakhstan has one of the fastest‐growing HIV epidemics in the world, with increasing rates among adolescents and young adults (AYA). Innovative strategies are needed to increase HIV testing uptake and decrease HIV stigma among AYA. Citizen science, defined as the active engagement of the general public in scientific research tasks, promotes and facilitates community engagement throughout the research process. This citizen science study used crowdsourcing to engage AYA in Kazakhstan to develop a digital intervention to reduce HIV stigma and promote HIV self‐testing. Our objectives in this paper are to describe the approach used, its feasibility and acceptability, and AYA motivations for and lessons learned collaborating on the study. Methods: From October 2021 to July 2022, in collaboration with a Community Collaborative Research Board and a Youth Advisory Board, we developed an open call requesting multimedia submissions to reduce HIV testing stigma. Eligible submissions were separated by age group (13−19 or 20−29 years) and judged by a panel composed of AYA (n = 23), healthcare professionals (n = 12), and representatives from the local government and non‐governmental organizations (n = 17). Each entry was reviewed by at least four judges and ranked on a 5‐point scale. The top 20 open call contestants were asked to submit self‐recordings sharing their motivation for and experience participating in the contest and lessons learned. Descriptive statistics were calculated for quantitative data. Qualitative data were coded using open coding. Results: We received 96 submissions from 77 youth across Kazakhstan. Roughly, three‐quarters (n = 75/96) of entries met judging eligibility criteria. Of the eligible entries, over half (n = 39/75) scored 3.5 or higher on a 5‐point scale (70.0%). The most frequent types of entries were video (n = 36/96, 37.5%), image (n = 28/96, 29.2%) and text (n = 24/96, 25.0%). AYA's primary motivations for collaborating on the study included a desire to improve society and help youth. The main challenges included creating content to address complex information using simple language, finding reliable information online and technological limitations. Conclusions: Crowdsourcing was feasible and highly acceptable among AYA in Kazakhstan. Citizen science approaches hold great promise for addressing the increasingly complex health and social challenges facing communities today. [ABSTRACT FROM AUTHOR]

Introduction: Russia's invasion of Ukraine in February 2022 has severely impacted the healthcare system, including the provision of HIV care. The ongoing war is a human‐caused mass trauma, a severe ecological and psychosocial disruption that greatly exceeds the coping capacity of the community. The bioecological model of mass trauma builds on Bronfenbrenner's concept of interaction between nested systems to argue that social context determines the impact of life events on the individual and how an individual responds. This paper uses the bioecological model of mass trauma to explore the impact of Russia's aggression against Ukraine and the ongoing war on HIV‐positive people who use drugs in Ukraine, a particularly vulnerable population that may be negatively affected by disruptions to social networks, healthcare infrastructure and economic conditions caused by mass trauma. Methods: Data were collected between September and November 2022. A convenience sample of 18 HIV‐positive people who use drugs were recruited from community organizations that work with people living with HIV, drug treatment programmes, and HIV clinics through direct recruitment and participant referral. A total of nine men and nine women were recruited; the age ranged from 33 to 62 years old (mean = 46.44). Participants completed a single interview that explored how the war had affected their daily lives and access to HIV care and other medical services; their relationships with healthcare providers and social workers; and medication access, supply and adherence. Data were analysed using the Framework Method for thematic analysis. Results: The war had a profound impact on the social, emotional and financial support networks of participants. Changes in social networks, coupled with limited job opportunities and rising prices, intensified financial difficulties for participants. Relocating to different regions of Ukraine, staying at somebody else's home, and losing connections with social workers impacted medication adherence and created lengthy treatment gaps. Participants also experienced a decreased supply of antiretroviral therapy, concerns about accessing medication for opioid use disorder, and overwhelming fears associated with the war, which overshadowed their HIV‐related health concerns and negatively impacted medication adherence. Conclusions: Our analysis reveals the complex impact of war on social networks and healthcare access. Maintaining support networks and competent healthcare providers will be essential amid the ongoing war. [ABSTRACT FROM AUTHOR]

Introduction: Programme Science (PS) and community‐led monitoring (CLM) intersect in unexpected and promising ways. This commentary examines a CLM initiative in Malawi and South Africa to highlight the crucial role of CLM in bolstering the PS framework. By leveraging data sources often overlooked by conventional research and evaluation approaches, CLM emerges as a pivotal element in enhancing programme effectiveness. This paper delineates the fundamental principles of CLM, presents programme outcomes derived from CLM methodologies and contextualizes these findings within the broader framework of PS. Discussion: The Citizen Science Project implements CLM continuously at 33 health facilities: 14 in Malawi (eight in Kasungu District and six in Dedza District), and 19 in South Africa (all in the West Rand District), representing a total catchment area of 989,848 people. Monitoring indicators are developed in an iterative process with community groups. The indicators are unique to each country, but both focus on the uptake of health services (quantitative) and barriers to access (qualitative). Monthly clinic records surveys capture 34 indicators in Malawi and 20 in South Africa and are supplemented by qualitative interviews with care recipients and healthcare workers. Qualitative interviews provide additional granularity and help confirm and explain the more macro trends in service coverage as described in quantitative data. The resulting data analysis reveals key themes that help stakeholders and decision‐makers to solve problems collaboratively. Noteworthy outcomes include a substantial increase in multi‐month dispensing of antiretroviral therapy (ART) during COVID‐19 (from 6% to 31%) with a subsequent recovery surpassing of HIV service benchmarks in Malawi post‐pandemic. Conclusions: While quantifying direct impact remains challenging due to the project's design, CLM proves to be a robust methodology that generates credible data and produces impactful outcomes. Its potential extends beyond the health sector, empowering community leadership and fostering interventions aligned with community needs. As CLM continues to evolve, its integration into PS promises to improve relevance, quality and impact across diverse disciplines. [ABSTRACT FROM AUTHOR]

HIV ,INFERENCE (Logic) - Abstract
In disease surveillance, capture-recapture methods are commonly used to estimate the number of diseased cases in a defined target population. Since the number of cases never identified by any surveillance system cannot be observed, estimation of the case count typically requires at least one crucial assumption about the dependency between surveillance systems. However, such assumptions are generally unverifiable based on the observed data alone. In this paper, we advocate a modeling framework hinging on the choice of a key population-level parameter that reflects dependencies among surveillance streams. With the key dependency parameter as the focus, the proposed method offers the benefits of (a) incorporating expert opinion in the spirit of prior information to guide estimation; (b) providing accessible bias corrections, and (c) leveraging an adapted credible interval approach to facilitate inference. We apply the proposed framework to two real human immunodeficiency virus surveillance datasets exhibiting three-stream and four-stream capture-recapture-based case count estimation. Our approach enables estimation of the number of human immunodeficiency virus positive cases for both examples, under realistic assumptions that are under the investigator's control and can be readily interpreted. The proposed framework also permits principled uncertainty analyses through which a user can acknowledge their level of confidence in assumptions made about the key non-identifiable dependency parameter.

Background: The COVID-19 pandemic affected the self-management and care of people living with HIV, requiring adaptations in the way health services are provided. However, it is unclear how these changes impacted HIV care in low-income countries. Methods: A systematic review including the current evidence related to changes in HIV care continuum during COVID-19 was conducted through a systematic search in the online databases including CINAHL, OVID-Medline, CAB Direct, and OVID-Embase. A two-step screening process was carried out to include eligible papers and reports according to inclusion criteria. Results: From the searches we identified 21 total studies published between 2021 and 2024, the studies revealed mostly negative impacts on all stages of the HIV care continuum in low-income countries. There were impacts related to the blocking measures due to COVID-19, fear of contracting the disease, difficulties in providing resources such as income, food and transports, reductions in the provision of care from prevention to viral suppression. Conclusion: Overall, researchers identified several negative impacts of COVID-19 restrictions on HIV care continuum during pandemic; however, some observations indicated indirect positive impacts on some aspects of HIV care. Decline in HIV care practices during pandemic compared to before pandemic were observed including using preventative methods, counseling and testing, receiving HIV healthcare services, HIV medical appointments, antiretroviral adherence, engagement with treatment, and poor viral suppression. However, in some evidence improvement in ART adherence and PrEP use were observed. [ABSTRACT FROM AUTHOR]

Background: Structural, interpersonal and individual level factors can present barriers for HIV prevention behaviour among people at high risk of HIV acquisition, including women who sell sex. In this paper we document the contexts in which women selling sex in Kampala meet and provide services to their clients. Methods: We collected qualitative data using semi-structured interviews. Women were eligible to participate if they were 18 years or older, self-identified as sex workers or offered sex for money and spoke Luganda or English. Ten women who met clients in venues and outdoor locations were selected randomly from a clinic for women at high risk of HIV acquisition. Ten other women who met clients online were recruited using snowball sampling. Interviews included demographic data, and themes included reasons for joining and leaving sex work, work locations, nature of relationships with clients and peers, interaction with authorities, regulations on sex work, and reported stigma. We conducted interviews over three months. Data were analysed thematically using a framework analysis approach. The coding framework was based on structural factors identified from literature, but also modified inductively with themes arising from the interviews. Results: Women met clients in physical and virtual spaces. Physical spaces included venues and outdoor locations, and virtual spaces were online platforms like social media applications and websites. Of the 20 women included, 12 used online platforms to meet clients. Generally, women from the clinic sample were less educated and predominantly unmarried, while those from the snowball sample had more education, had professional jobs, or were university students. Women from both samples reported experiences of stigma, violence from clients and authorities, and challenges accessing health care services due to the illegality of sex work. Even though all participants worked in settings where sex work was illegal and consequently endured harsh treatment, those from the snowball sample faced additional threats of cybersecurity attacks, extortion from clients, and high levels of violence from clients. Conclusions: To reduce risk of HIV acquisition among women who sell sex, researchers and implementers should consider these differences in contexts, challenges, and risks to design innovative interventions and programs that reach and include all women.

This paper tackles the complex interplay between Human Immunodeficiency virus (HIV-1) and Mycobacterium tuberculosis (M. tuberculosis) infections, particularly their contribution to immunosenescence, the age-related decline in immune function. Using the current literature, we discuss the immunological mechanisms behind TB and HIV-induced immunosenescence and critically evaluate the BCG (Bacillus Calmette-Guérin) vaccine's role. Both HIV-1 and M. tuberculosis demonstrably accelerate immunosenescence: M. tuberculosis through DNA modification and heightened inflammation, and HIV-1 through chronic immune activation and T cell production compromise. HIV-1 and M. tuberculosis co-infection further hastens immunosenescence by affecting T cell differentiation, underscoring the need for prevention and treatment. Furthermore, the use of the BCG tuberculosis vaccine is contraindicated in patients who are HIV positive and there is a lack of investigation regarding the use of this vaccine in patients who develop HIV co-infection with possible immunosenescence. As HIV does not currently have a vaccine, we focus our review more so on the BCG vaccine response as a result of immunosenescence. We found that there are overall limitations with the BCG vaccine, one of which is that it cannot necessarily prevent re-occurrence of infection due to effects of immunosenescence or protect the elderly due to this reason. Overall, there is conflicting evidence to show the vaccine's usage due to factors involving its production and administration. Further research into developing a vaccine for HIV and improving the BCG vaccine is warranted to expand scientific understanding for public health and beyond. [ABSTRACT FROM AUTHOR]

The battle against viral drug resistance highlights the need for innovative approaches to replace time-consuming and costly traditional methods. Deep generative models offer automation potential, especially in the fight against Human immunodeficiency virus (HIV), as they can synthesize diverse molecules effectively. In this paper, an application of an LSTM-based deep generative model named "LSTM-ProGen" is proposed to be tailored explicitly for the de novo design of drug candidate molecules that interact with a specific target protein (HIV-1 protease). LSTM-ProGen distinguishes itself by employing a long-short-term memory (LSTM) architecture, to generate novel molecules target specificity against the HIV-1 protease. Following a thorough training process involves fine-tuning LSTM-ProGen on a diverse range of compounds sourced from the ChEMBL database. The model was optimized to meet specific requirements, with multiple iterations to enhance its predictive capabilities and ensure it generates molecules that exhibit favorable target interactions. The training process encompasses an array of performance evaluation metrics, such as drug-likeness properties. Our evaluation includes extensive silico analysis using molecular docking and PCA-based visualization to explore the chemical space that the new molecules cover compared to those in the training set. These evaluations reveal that a subset of 12 de novo molecules generated by LSTM-ProGen exhibit a striking ability to interact with the target protein, rivaling or even surpassing the efficacy of native ligands. Extended versions with further refinement of LSTM-ProGen hold promise as versatile tools for designing efficacious and customized drug candidates tailored to specific targets, thus accelerating drug development and facilitating the discovery of new therapies for various diseases.

Background: Depression is a very common psychiatric disorder in worldwide. Globally, Human Immunodeficiency Virus (HIV) is highly prevalent among women, and are disproportionately affected by depression. Antiretroviral Therapy (ART) adherence which could highly be affected by depression is yet to be explored effectively. Depression affects overall poor HIV clinical outcomes, socioeconomic and social interactions. However, it is not well understood specifically how depression affects ART adherence in women living with HIV (WLWHIV). Investigating the effects of depression on ART adherence is critical in order to develop nuanced new evidence to address non-adherence in WLWHIV. Objective: To conduct a meta-analysis on the correlation between depression and adherence to antiretroviral therapy among women living with HIV in the globe. Method: Using population, exposed and outcome approach, we searched Scopus, PubMed, EMBASE, Cochrane Library, Psych info, Web of science and google scholar for cohort and cross-sectional studies globally. The search strategy was structured comprising terms associated with antiretroviral therapy and adherence, women living with HIV and depression. We evaluated the paper quality, using the Newcastle-Ottawa Scales (NOS). The fixed effect model was used to analysis the effect of depression on ART adherence. Result: A total of 8 articles comprise 6474 participants were included in this study. There were controversial findings related to the effect of depression to ART adherence. Among three cross-sectional study, one article demonstrating, depression was associated with ART adherence. Of the five cohort studies, four cohort studies reported association. The overall pooled estimated effect of depression on ART adherence was 1.02 [RR = 1.015 with 95% CI (1.004, 1.026)] with a p-value of 0.005. Conclusion and recommendation: Depression was the risk factor for ART adherence among women living with HIV. It is therefore, necessary for clinician to note this and perform screening for ART adherence. Trial registration: The review protocol was developed with prospero registration:CRD42023415935.

This paper analyzes the implications of illness and queerness for the identity Gil de Biedma constructs through his personal diary of 1985. This is a unique case of a Spanish author providing a complex picture of the effect of HIV/AIDS on his own life and work. In addition, the author's diaries are a rare example of Spanish autobiographical writing on illness. Gil de Biedma kept several diaries throughout his life. The last diary, titled "Diario de 1985", is an account of his stay at a French hospital while undergoing treatment for Kaposi's sarcoma. This short diary offers crude yet insightful material on human illness, suffering and the stigma of HIV/AIDS in Spain during the 1980s. By close reading a selection of fragments of the author's diary, utilizing an approach that combines psychoanalysis and social history, this paper exposes the connections between illness, sexuality and identity in Gil de Biedma's autobiographical writing. This paper claims that Gil de Biedma (un)consciously represses naming the illness in his diaries while being very descriptive about the physical symptoms of AIDS and its treatment. This evidences the brutal social and familial pressure to conform to a certain identity, ultimately giving way to a very particular symbiosis between the author's literary persona and his bourgeois self.

In this paper, a dynamic HIV model with cell-to-cell transmission, two immune responses, and induced apoptosis is proposed and studied. First, the non-negativity and boundedness of the solutions of the model are given, and then the exact expression of the basic reproduction number R0 is obtained by using the next generation matrix method. Second, criteria are obtained for the local stability of the disease-free equilibrium, immune response-free equilibrium, and the infected equilibrium with both humoral and cellular immune responses. Furthermore, the threshold conditions are also derived for the global asymptotic stability of the disease-free equilibrium, immune responsefree equilibrium, and the infected equilibrium with both humoral and cellular immune responses by constructing the suitable Lyapunov function. Finally, some numerical simulations are conducted to verify the theoretical results; the numerical simulation results show that the increase of apoptosis rate had a positive role in the control of viral infection.

Human Immunodeficiency Virus (HIV) is a stigmatizing disease that disproportionately affects African Americans and Latinos among people living with HIV (PLWH). Researchers are increasingly utilizing artificial intelligence (AI) to analyze large amounts of data such as social media data and electronic health records (EHR) for various HIV-related tasks, from prevention and surveillance to treatment and counseling. This paper explores the ethical considerations surrounding the use of AI for HIV with a focus on acceptability, trust, fairness, and transparency. To improve acceptability and trust towards AI systems for HIV, informed consent and a Federated Learning (FL) approach are suggested. In regard to unfairness, stakeholders should be wary of AI systems for HIV further stigmatizing or even being used as grounds to criminalize PLWH. To prevent criminalization, in particular, the application of differential privacy on HIV data generated by data linkage should be studied. Participatory design is crucial in designing the AI systems for HIV to be more transparent and inclusive. To this end, the formation of a data ethics committee and the construction of relevant frameworks and principles may need to be concurrently implemented. Lastly, the question of whether the amount of transparency beyond a certain threshold may overwhelm patients, thereby unexpectedly triggering negative consequences, is posed. [ABSTRACT FROM AUTHOR]

In this paper, we analyze the global asymptotic behaviors of a mathematical susceptibleinfected(SI) age-infection-structured human immunodeficiency virus(HIV) model with heterogeneous transmission. Mathematical analysis shows that the local and global dynamics are completely determined by the basic reproductive number R
0 . If R0 < 1, disease-free equilibrium is globally asymptotically stable. If R0 >1, it shows that diseasefree equilibrium is unstable and the unique endemic equilibrium is globally asymptotically stable. The proofs of global stability utilize Lyapunov functions. Besides, the numerical simulations are illustrated to support these theoretical results and sensitivity analysis of each parameter for R0 is performed by the method of partial rank correlation coefficient(PRCC).

Background: Antiretroviral therapy has led to AIDS being a chronic disease. Nevertheless, the presence of constantly emerging drug resistance mutations poses a challenge to clinical treatment. A systematic analysis to summarize the advancements and uncharted territory of drug resistance mutations is urgently needed and may provide new clues for solving this problem. Methods: We gathered 3,694 publications on drug resistance mutations from the Web of Science Core Collection with CiteSpace software and performed an analysis to visualize the results and predict future new directions and emerging trends. Betweenness centrality, count, and burst value were taken as standards. Results: The number of papers on HIV medication resistance mutations during the last 10 years shows a wave-like trend. In terms of nation, organization, and author, the United States (1449), University of London (193), and Mark A. Wainberg (66) are the most significant contributors. The most frequently cited article is "Drug resistance mutations for surveillance of transmitted HIV-1 drug-resistance: 2009 update." Hot topics in this field include "next-generation sequencing," "tenofovir alafenamide," "children," "regimens," "accumulation," "dolutegravir," "rilpivirine," "sex," "pretreatment drug resistance," and "open label." Research on drug resistance in teenagers, novel mutation detection techniques, and drug development is ongoing, and numerous publications have indicated the presence of mutations related to current medications. Therefore, testing must be performed regularly for patients who have used medications for a long period. Additionally, by choosing medications with a longer half-life, patients can take fewer doses of their prescription, increasing patient compliance. Conclusion: This study involved a bibliometric visualization analysis of the literature on drug resistance mutations, providing insight into the field's evolution and emerging patterns and offering academics a resource to better understand HIV drug resistance mutations and contribute to the field's advancement.

Despite combined antiretroviral therapy (cART) limiting HIV replication to undetectable levels in the blood, people living with HIV continue to experience HIV-associated neurocognitive disorder (HAND). HAND is associated with neurocognitive impairment, including motor impairment, and memory loss. HIV has been detected in the brain within 8 days of estimated exposure and the mechanisms for this early entry are being actively studied. Once having entered into the central nervous system (CNS), HIV degrades the blood–brain barrier through the production of its gp120 and Tat proteins. These proteins are directly toxic to endothelial cells and neurons, and propagate inflammatory cytokines by the activation of immune cells and dysregulation of tight junction proteins. The BBB breakdown is associated with the progression of neurocognitive disease. One of the main hurdles for treatment for HAND is the latent pool of cells, which are insensitive to cART and prolong inflammation by harboring the provirus in long-lived cells that can reactivate, causing damage. Multiple strategies are being studied to combat the latent pool and HAND; however, clinically, these approaches have been insufficient and require further revisions. The goal of this paper is to aggregate the known mechanisms and challenges associated with HAND. [ABSTRACT FROM AUTHOR]

The HIV/AIDS pandemic is a global issue that has unequally affected several countries. Due to the complexity of this condition and the human drama it represents to those most affected by it, several fields have contributed to solving or at least alleviating this situation, and the information systems (IS) field has not been absent from these efforts. With the importance of antiretroviral therapy (ART) as a starting point, several initiatives in the IS field have focused on ways to improve the adherence and effectiveness of this therapy: mobile phone reminders (for pill intake and appointments), and mobile interfaces between patients and health workers are popular contributions. However, many of these solutions have been difficult to implement or deploy in some countries in the Global South, which are among the most affected by this pandemic. This paper presents one such case. Using a case‐study approach with an extreme‐case selection technique, the paper studies an m‐health system for HIV patients in the Kalangala region of Uganda. Using Heeks' design—reality gap model for data analysis, the paper shows that the rich interaction between social context and technology should be considered a central concern when designing or deploying such systems.

Human Immunodeficiency Virus (HIV) significantly increases the risk of various cancers due to chronic immune suppression and viral oncogenes. Traditional therapies, including antiretroviral therapy (ART), chemotherapy, and radiation, often face limitations such as drug resistance and systemic toxicity. PROteolysis TArgeting Chimeras (PROTACs) have emerged as a promising approach for targeted protein degradation, offering significant advantages over conventional treatments. However, effective delivery remains a challenge. This paper explores the innovative use of tear exosome‐based delivery systems for PROTACs in treating HIV‐mediated cancers. Tear exosomes, due to their natural origin, biocompatibility, and inherent targeting capabilities, present a novel and effective platform for delivering PROTACs, enhancing therapeutic specificity and reducing adverse effects. Integrating the unique properties of tear exosomes with the therapeutic potential of PROTACs could revolutionize the treatment of HIV‐mediated cancers by overcoming current therapeutic challenges and improving patient outcomes.

This article discusses the increasing number of HIV diagnoses and AIDS-related deaths in Turkey, particularly among the trans community. The research focuses on the experiences of HIV-positive trans women who engage in sex work and the violence they face from healthcare providers. The paper argues that trans women are treated as always infectious, leading to denial of medical care and reluctance to touch or examine them. The study highlights the urgent need for comprehensive interventions to address the intersecting issues of HIV risk, structural violence, and discrimination faced by HIV-positive trans sex workers.

Background: Prevention of mother-to-child transmission (PMTCT) of HIV service is conceptualized as a series of cascades that begins with all pregnant women and ends with the detection of a final HIV status in HIV-exposed infants (HEIs). A low rate of cascade completion by mothers' results in an increased risk of HIV transmission to their infants. Therefore, this review aimed to understand the uptake and determinants of key PMTCT services cascades in East Africa. Methods: We searched CINAHL, EMBASE, MEDLINE, Scopus, and AIM databases using a predetermined search strategy to identify studies published from January 2012 through to March 2022 on the uptake and determinants of PMTCT of HIV services. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. A random-effects model was used to obtain pooled estimates of (i) maternal HIV testing (ii) maternal ART initiation, (iii) infant ARV prophylaxis and (iv) early infant diagnosis (EID). Factors from quantitative studies were reviewed using a coding template based on the domains of the Andersen model (i.e., environmental, predisposing, enabling and need factors) and qualitative studies were reviewed using a thematic synthesis approach. Results: The searches yielded 2231 articles and we systematically reduced to 52 included studies. Forty quantitative, eight qualitative, and four mixed methods papers were located containing evidence on the uptake and determinants of PMTCT services. The pooled proportions of maternal HIV test and ART uptake in East Africa were 82.6% (95% CI: 75.6–88.0%) and 88.3% (95% CI: 78.5–93.9%). Similarly, the pooled estimates of infant ARV prophylaxis and EID uptake were 84.9% (95% CI: 80.7–88.3%) and 68.7% (95% CI: 57.6–78.0) respectively. Key factors identified were the place of residence, stigma, the age of women, the educational status of both parents, marital status, socioeconomic status, Knowledge about HIV/PMTCT, access to healthcare facilities, attitudes/perceived benefits towards PMTCT services, prior use of maternal and child health (MCH) services, and healthcare-related factors like resource scarcity and insufficient follow-up supervision. Conclusion: Most of the identified factors were modifiable and should be considered when formulating policies and planning interventions. Hence, promoting women's education and economic empowerment, strengthening staff supervision, improving access to and integration with MCH services, and actively involving the community to reduce stigma are suggested. Engaging community health workers and expert mothers can also help to share the workload of healthcare providers because of the human resource shortage. [ABSTRACT FROM AUTHOR]

Chronic HIV-1 infection can cause neurological illness, also known as HIV-associated neurocognitive disorders (HAND). The elevated level of pro-inflammatory cytokines and chemokines, such as C-C Chemokine Ligand 5 (CCL5/RANTES), is one of the ways of causing HIV-1-mediated neuroinflammation. C-C Chemokine Receptor 5 (CCR5) is the main coreceptor for viral entry into host cells and for mediating induction of CCL5/RANTES. CCR5 and CCL5 are part of a correlated axis of immune pathways used for effective protection against the HIV-1 virus. The purpose of this paper was to review the literary knowledge about the immunopathological relationship between this immune complex and neuroAIDS. A systematic review of the literature was conducted based on the selection and search of articles, available in English, Spanish, or Portuguese in the time frame of 1990–2022, of primary and secondary types in the PUBMED, Science Direct, SciELO, and LILACS databases through descriptors (MeSH) together with "AND": "CCR5"; "CCL5"; "neurological manifestations"; or "HIV". The methodological quality of the articles was assessed using the JBI Checklists and the PRISMA 2020 writing guidelines were followed. A total of 36 articles were included in the final composition of the review. The main cells of the CNS affected by neuroAIDS are: neurons; microglia; astrocytes; and oligodendrocytes. Molecular devices and their associations with cellular injuries have been described from the entry of the virus into the host's CNS cell to the generation of mental disorders. Furthermore, divergent results were found about the levels of CCL5/RANTES secretion and the generation of immunopathogenesis, while all condensed research for CCR5 indicated that elevation of this receptor causes more neurodegenerative manifestations. Therefore, new therapeutic and interventional strategies can be conditioned on the immunological direction proposed in this review for the disease. [ABSTRACT FROM AUTHOR]

This paper develops a mathematical model to investigate the Human Immunodeficiency Virus (HIV) infection dynamics. The model includes two transmission modes (cell-to-cell and cell-free), two adaptive immune responses (cytotoxic T-lymphocyte (CTL) and antibody), a saturated CTL immune response, and latent HIV infection. The existence and local stability of equilibria are fully characterized by four reproduction numbers. Through sensitivity analyses, we assess the partial rank correlation coefficients of these reproduction numbers and identify that the infection rate via cell-to-cell transmission, the number of new viruses produced by each infected cell during its life cycle, the clearance rate of free virions, and immune parameters have the greatest impact on the reproduction numbers. Additionally, we compare the effects of immune stimulation and cell-to-cell spread on the model's dynamics. The findings highlight the significance of adaptive immune responses in increasing the population of uninfected cells and reducing the numbers of latent cells, infected cells, and viruses. Furthermore, cell-to-cell transmission is identified as a facilitator of HIV transmission. The analytical and numerical results presented in this study contribute to a better understanding of HIV dynamics and can potentially aid in improving HIV management strategies.

Background: Partner notification (PN) is key to controlling sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Digital PN options (e.g. social media, short message service (SMS), emails) are promising in increasing PN behaviour. However, their implementation is often challenging and studies report varied levels of acceptability and uptake of PN, highlighting the need to optimise digital PN interventions. Methods: A systematic review of barriers and facilitators to digital PN interventions for STIs, including HIV, across eight research databases (from 2010 to 2023) identified eight relevant studies, two of which addressed HIV. Data extraction identified 98 barriers and 54 facilitators to the use of digital PN interventions. These were synthesised into 18 key barriers and 17 key facilitators that were each deemed amenable to change. We then used the Behaviour Change Wheel approach, the Acceptability, Practicability, Effectiveness, Affordability, Side-effects and Equity criteria, and multidisciplinary expert input, to systematically develop practical recommendations to optimise digital PN. Results: Thirty-two specific recommendations clustered around three themes. Digital PN interventions should: (1) empower and support the index patient by providing a range of notification options, accompanied by clear instructions; (2) integrate into users' existing habits and the digital landscape, meeting contemporary standards and expectations of usability; and (3) address the social context of PN both online and offline through normalising the act of PN, combating STI-related stigma and stressing the altruistic aspects of PN through consistent messaging to service users and the public. Conclusions: Our evidence-based recommendations should be used to optimise existing digital PN interventions and inform the co-production of new ones. This paper systematically develops recommendations to improve current and future digital partner notification interventions. It takes findings from the published international literature and then uses tools from behavioural science to generate a series of simple recommendations. The recommendations should be further operationalised locally with key stakeholders for optimal impact. [ABSTRACT FROM AUTHOR]
