Real-world data to improve organ and tissue donation policies: lessons learned from the tissue and organ donor epidemiology study

Abstract Background The transplantation of human organs, and some human tissues, is often the only life-saving therapy available for serious and life-threatening congenital, inherited or acquired diseases. However, it is associated with a risk of transmission of communicable diseases from donor to recipient. It is imperative to understand the characteristics of the donor population (including both potential and actual donors) to inform policies that protect recipient safety. The Tissue and Organ Donor Epidemiology Study (TODES) was a pilot project designed to identify and collect standardized information on deceased persons referred for organ, tissue and/or eye donation, and to estimate (to the extent possible) infectious disease prevalence and incidence of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) in this population. TODES is summarized here to shed light on addressable limitations on accessing data needed for transplant recipient safety. Limitations, future research needs and potential pathways to solve the remaining data needs are explored. Methods Retrospective data for all deceased donors during a 5-year period from 2009 to 2013 were obtained from participating organ procurement organizations (OPOs), tissue establishments and eye banks. These decedent data were used to ascertain whether the available real-world data (RWD) could be used to inform donor screening and testing policy. Results The TODES database contains 291 848 records received from nine OPOs and 42 451 records received from four eye banks. Data were analysed from deceased donors with at least one organ, tissue or ocular tissue recovered with the intent to transplant. Results for potential donors were not analysed. Available RWD at the time of the TODES study were not fit-for-purpose to help characterize the organ, tissue and eye donor populations and/or to inform donor screening policy. Conclusions Recent advances in electronic data collection systems make it more realistic to now collect fit-for-purpose RWD that address the research needed to improve transplant safety.

Epidemiology of HIV infection in penal system institutions

Aim. To assess the medical and statistical indicators of the health status of persons with the disease caused by the human immunodeficiency virus (HIV), among suspects, accused, and convicts held in institutions of the penal system. To develop proposals for improving work in the field of countering the spread of HIV infections. Materials and methods. The structure and dynamics of morbidity and mortality from HIV infection in penal institutions from 2014 to 2022 was analyzed using official statistical data. Calculations were carried out using MS Excel application packages and the R software environment version 3.6.2.Results. The peak HIV incidence in penal system institutions was recorded in 2015, followed by its gradual decrease by 2020. HIV mortality decreased by 52.1% since 2014, amounting to 84.6 per 100,000 people in 2022. The mortality rate of people living with HIV (PLHIV) decreased by 61.5% in 2014. This dynamics showed a decreasing trend starting from 2015. The antiretroviral therapy coverage in this group of patients reached a maximum value of 94.5% by 2022. Conclusions. The HIV mortality and mortality rates during the study period show a downward trend. The antiretroviral therapy coverage in 2022 reached a historic maximum. However, this does not exclude the low adherence of patients to treatment, which indicates the need to develop new methods of sanitary education and therapeutic and preventive work in penal system institutions.

Improvement in the 95-95-95 Targets Is Accompanied by a Reduction in Both the Human Immunodeficiency Virus Transmission Rate and Incidence in China.

In 2016, China has implemented the World Health Organization's "treat all" policy. We aimed to assess the impact of significant improvements in the 95-95-95 targets on population-level human immunodeficiency virus (HIV) transmission dynamics and incidence. We focused on 3 steps of the HIV care continuum: diagnosed, on antiretroviral therapy, and achieving viral suppression. The molecular transmission clusters were inferred using HIV-TRACE. New HIV infections were estimated using the incidence method in the European Centre for Disease Prevention and Control HIV Modelling Tool. Between 2004 and 2023, the national HIV epidemiology database recorded 2.99 billion person-times of HIV tests and identified 1 976 878 new diagnoses. We noted a roughly "inverted-V" curve in the clustering frequency, with the peak recorded in 2014 (67.1% [95% confidence interval, 63.7%-70.5%]), concurrent with a significant improvement in the 95-95-95 targets from 10-13-<71 in 2005 to 84-93-97 in 2022. Furthermore, we observed a parabolic curve for a new infection with the vertex occurring in 2010. In general, it was suggested that the improvements in the 95-95-95 targets were accompanied by a reduction in both the population-level HIV transmission rate and incidence. Thus, China should allocate more effort to the first "95" target to achieve a balanced 95-95-95 target.

Perceptions of patients and healthcare providers regarding barriers and enablers of HIV anti-retroviral therapy among women at a regional hospital in Ghana: implications for national HIV/AIDS control

BackgroundThe Acquired Immune Deficiency Syndrome (AIDS) pandemic has created a lot of devastation over the last four decades and continues to be a public health threat. Anti-retroviral treatment (ART), a group of medications that people who have been diagnosed with the Human Immunodeficiency Virus (HIV) infection take, has been shown to be efficacious and has significantly improved the fight against the disease. In Ghana, women carry a higher prevalence and incidence of HIV. The study’s objectives were to understand the experiences of women living with HIV/AIDS on ART and determine the barriers and enablers for ART uptake from the perspective of both the females living with HIV and their healthcare providers in the Upper East Regional Hospital of Ghana.MethodsThis was a qualitative study that used interviews to acquire data from women living with HIV on the perceived barriers and enablers for ART. The Upper East Regional Hospital in Ghana was the study site. We used a phenomenological approach to explore the lived experiences, perceptions, and meanings associated with ART among women. We collected data until we reached thematic saturation, interviewing a total of sixteen women living with HIV. We conducted a focus group discussion with nine healthcare workers providing care at the ART clinic. Data were analysed using thematic analysis.ResultsWomen living with HIV and their healthcare providers viewed an environment that provided encouragement and support from healthcare workers and patients’ relatives, the ability to conceal HIV status, peer counselling, and the perceived benefits of therapy as enablers of ART uptake and medication adherence. The following were barriers to ART uptake and adherence: ill health, forgetfulness, long distances to ART clinics, cultural and spiritual beliefs, and fear of stigma.ConclusionsEnablers of ART uptake should be expanded upon and encouraged so that women living with HIV/AIDS can access drugs in a timely and stress-free manner. On the other hand, the barriers identified can be addressed through education, the expansion of healthcare infrastructure, and the economic empowerment of women.

Multivariate Poisson cokriging: A geostatistical model for health count data.

Multivariate disease mapping is important for public health research, as it provides insights into spatial patterns of health outcomes. Geostatistical methods that are widely used for mapping spatially correlated health data encounter challenges when dealing with spatial count data. These include heterogeneity, zero-inflated distributions and unreliable estimation, and lead to difficulties when estimating spatial dependence and poor predictions. Variability in population sizes further complicates risk estimation from the counts. This study introduces multivariate Poisson cokriging for predicting and filtering out disease risk. Pairwise correlations between the target variable and multiple ancillary variables are included. By means of a simulation experiment and an application to human immunodeficiency virus incidence and sexually transmitted diseases data in Pennsylvania, we demonstrate accurate disease risk estimation that captures fine-scale variation. This method is compared with ordinary Poisson kriging in prediction and smoothing. Results of the simulation study show a reduction in the mean square prediction error when utilizing auxiliary correlated variables, with mean square prediction error values decreasing by up to 50%. This gain is further evident in the real data analysis, where Poisson cokriging yields a 74% drop in mean square prediction error relative to Poisson kriging, underscoring the value of incorporating secondary information. The findings of this work stress on the potential of Poisson cokriging in disease mapping and surveillance, offering richer risk predictions, better representation of spatial interdependencies, and identification of high-risk and low-risk areas.

Implementing pathogen reduction technology while discontinuing blood donor deferral criteria for sexual risk behaviors: A simulation study.

Combining pathogen reduction technology (PRT) with blood screening may alleviate concerns over the risk of transfusion-transmitted infections (TTI) and support changes in blood donor selection to potentially increase blood availability. This study aimed to estimate the residual risk of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) transfusion-transmission in Canada after implementing PRT, while eliminating deferrals for sexual risk behaviors. A probabilistic approach that combined Bayesian networks with Monte Carlo simulations was used to estimate the risk of transfusing HIV-, HBV-, or HCV-contaminated blood components. Different scenarios were considered to compare the current residual risk after PRT implementation, with and without donor deferral criteria for sexual risk behaviors. Donor profiles and blood component outcomes were simulated based on a literature review including the prevalence and incidence of HIV, HBV, and HCV in the Canadian blood donor population; the use of current blood screening assays; and HIV, HBV, and HCV blood donor viral loads. In the universal PRT scenario (i.e., with PRT/without deferral criteria), the estimated risks of HIV, HBV, and HCV transmission were significantly lower than those in the currently observed scenario (i.e., without PRT/with deferral criteria). This risk model suggests that PRT for platelets and plasma (and eventually for RBCs when available) significantly reduces the residual risks of HIV, HBV and HCV transfusion-transmission and could enable the removal of blood donor deferral criteria for sexual risk behaviors.

Trends in HIV incidence and mortality across Bharat (India) after the emergence of COVID-19.

Human immunodeficiency virus (HIV) is a sexually transmitted infection impacting populations worldwide. While there have been major improvements in controlling HIV over recent years, the COVID-19 pandemic may have potentially resulted in major interruptions to this control of HIV. Bharat (India) is a country that has been greatly impacted by the COVID-19 pandemic, and we aimed to analyse the trends in HIV control since the start of the pandemic. In this study we evaluated changes in rates of HIV incidence and mortality across Bharat for the years both before, and after, the start of the COVID-19 pandemic. Percent and absolute changes were determined, and thereafter, both bivariate and multi linear regression was conducted to evaluate the relationship between COVID-19 burden and changes in HIV epidemiology across the nation. It was shown that, despite the COVID-19 pandemic, annual incidence and deaths of HIV/AIDS have both decreased across Bharat. From 2019-2021, in Bharat, the total number of new HIV cases annually decreased by 9.03%, and the total number of HIV/AIDS deaths annually decreased by 28.82%. A similar trend was shown across most states/union territories; however, there were notable exceptions (such as Karnataka, Bihar, and Assam) where the rates have instead increased. Our analysis has demonstrated that government efforts to control the HIV/AIDS epidemic have not been greatly impacted across the majority of Bharat since the emergence of COVID-19. The reduction in annual HIV/AIDS deaths in the country has been better than the world average, and the improvements from the period of 2019 to 2021 were greater than those from 2017 to 2019. Regardless, there are regions in the nation where the epidemic has instead worsened during this period.

Modelling the role of tourism in the spread of HIV: A case study from Malaysia

This study aimed to assess the role of tourism in the spread of human immunodeficiency virus (HIV) using Malaysian epidemiological data on HIV and acquired immunodeficiency syndrome (AIDS) incidence from 1986 to 2004. A population-level mathematical model was developed with the following compartments: the population susceptible to HIV infection, the clinically confirmed HIV-positive population, the population diagnosed with AIDS, and the tourist population. Additionally, newborns infected with HIV were considered. Sensitivity analyses and variations in fixed parameter values were used to explore the effect of changes to various parameter values on HIV incidence in the model. It was determined that variations in the rate of HIV-positive inbound tourist entries and the rate of foreign tourist exits (i.e., the duration of time tourists spent in Malaysia) significantly impacted the predicted incidence of HIV and AIDS in Malaysia. The model's fit to observed HIV and AIDS incidence was evaluated, resulting in adjusted R2 values of 53.3% and 53.2% for HIV and AIDS, respectively. Furthermore, the reproduction number (R0) was also calculated to quantify the stability of the HIV endemicity in Malaysia. The findings suggest that a steady-state level of HIV in Malaysia is achievable based on the low value of R0 = 0.0136, and the disease-free equilibrium was stable from the negative eigenvalues obtained, which is encouraging from a public health perspective. The Partial Rank Correlation Coefficient (PRCC) values between the proportion of newborns born HIV-positive, the rate of Malaysian tourist entries returning home after contracting HIV, and the rate of foreign tourist exits have a significant impact on the R0. The methods provide a framework for epidemiological modelling of HIV spread through transient population groups. The model results suggest that the role of tourism should not be overlooked within the set of available measures to mitigate the spread of HIV.

Illicit Fentanyl Use and Hepatitis C Virus Seroconversion Among People Who Inject Drugs in Tijuana and San Diego: Results From a Binational Cohort Study.

Illicitly manufactured fentanyl (IMF) increases overdose mortality, but its role in infectious disease transmission is unknown. We examined whether IMF use predicts hepatitis C virus (HCV) and human immunodeficiency virus (HIV) incidence among a cohort of people who inject drugs (PWID) in San Diego, California and Tijuana, Mexico. PWID were recruited during 2020-2022, undergoing semi-annual interviewer-administered surveys and HIV and HCV serological rapid tests through 2024. Cox regression was conducted to examine predictors of seroconversion considering self-reported IMF use as a 6-month lagged, time-dependent covariate. Of 398 PWID at baseline, 67% resided in San Diego, 70% were male, median age was 43 years, 42% reported receptive needle sharing, and 25% reported using IMF. HCV incidence was 14.26 per 100 person-years (95% confidence interval [CI]: 11.49-17.02), and HIV incidence was 1.29 (95% CI: .49-2.10). IMF was associated with HCV seroconversion, with a univariable hazard ratio (HR) of 1.64 (95% CI: 1.09-2.40), and multivariable HR of 1.57 (95% CI: 1.03-2.40). The direction of the relationship with HIV was similar, albeit not significant (HR 2.39; 95% CI: .66-8.64). We document a novel association between IMF and HCV seroconversion among PWID in Tijuana-San Diego. Few HIV seroconversions (n = 10) precluded our ability to assess if a similar relationship held for HIV. IMF's short half-life may destabilize PWID-increasing the need for repeat dosing and sharing smoking materials and syringes. New preventive care approaches may reduce HCV transmission in the fentanyl era.

Testing and Treatment Interventions in Community Settings Key to Controlling a Recent Human Immunodeficiency Virus Outbreak Among People Who Inject Drugs in Glasgow: A Modeling Study.

A human immunodeficiency virus (HIV) outbreak was identified among people who inject drugs (PWID) in Glasgow in 2015, with >150 diagnoses by the end of 2019. The outbreak response involved scaling up HIV testing and improving HIV treatment initiation and retention. We parameterized and calibrated a dynamic, deterministic model of HIV transmission among PWID in Glasgow to epidemiological data. We use this model to evaluate HIV testing and treatment interventions. We present results in terms of relative changes in HIV prevalence, incidence, and cases averted. If the improvements in both testing and treatment had not occurred, we predict that HIV prevalence would have reached 17.8% (95% credible interval [CrI], 14.1%-22.6%) by the beginning of 2020, compared to 5.9% (95% CrI, 4.7%-7.4%) with the improvements. If the improvements had been made on detection of the outbreak in 2015, we predict that peak incidence would have been 26.2% (95% CrI, 8.8%-49.3%) lower and 62.7% (95% CrI, 43.6%-76.6%) of the outbreak cases could have been averted. The outbreak could have been avoided if the improvements had already been in place. Our modeling suggests that the HIV testing and treatment interventions successfully brought the HIV outbreak in Glasgow under control by the beginning of 2020.

Twice-Yearly Lenacapavir or Daily F/TAF for HIV Prevention in Cisgender Women.

There are gaps in uptake of, adherence to, and persistence in the use of preexposure prophylaxis for human immunodeficiency virus (HIV) prevention among cisgender women. We conducted a phase 3, double-blind, randomized, controlled trial involving adolescent girls and young women in South Africa and Uganda. Participants were assigned in a 2:2:1 ratio to receive subcutaneous lenacapavir every 26 weeks, daily oral emtricitabine-tenofovir alafenamide (F/TAF), or daily oral emtricitabine-tenofovir disoproxil fumarate (F/TDF; active control); all participants also received the alternate subcutaneous or oral placebo. We assessed the efficacy of lenacapavir and F/TAF by comparing the incidence of HIV infection with the estimated background incidence in the screened population and evaluated relative efficacy as compared with F/TDF. Among 5338 participants who were initially HIV-negative, 55 incident HIV infections were observed: 0 infections among 2134 participants in the lenacapavir group (0 per 100 person-years; 95% confidence interval [CI], 0.00 to 0.19), 39 infections among 2136 participants in the F/TAF group (2.02 per 100 person-years; 95% CI, 1.44 to 2.76), and 16 infections among 1068 participants in the F/TDF group (1.69 per 100 person-years; 95% CI, 0.96 to 2.74). Background HIV incidence in the screened population (8094 participants) was 2.41 per 100 person-years (95% CI, 1.82 to 3.19). HIV incidence with lenacapavir was significantly lower than background HIV incidence (incidence rate ratio, 0.00; 95% CI, 0.00 to 0.04; P<0.001) and than HIV incidence with F/TDF (incidence rate ratio, 0.00; 95% CI, 0.00 to 0.10; P<0.001). HIV incidence with F/TAF did not differ significantly from background HIV incidence (incidence rate ratio, 0.84; 95% CI, 0.55 to 1.28; P = 0.21), and no evidence of a meaningful difference in HIV incidence was observed between F/TAF and F/TDF (incidence rate ratio, 1.20; 95% CI, 0.67 to 2.14). Adherence to F/TAF and F/TDF was low. No safety concerns were found. Injection-site reactions were more common in the lenacapavir group (68.8%) than in the placebo injection group (F/TAF and F/TDF combined) (34.9%); 4 participants in the lenacapavir group (0.2%) discontinued the trial regimen owing to injection-site reactions. No participants receiving twice-yearly lenacapavir acquired HIV infection. HIV incidence with lenacapavir was significantly lower than background HIV incidence and HIV incidence with F/TDF.

Factors Influencing Adolescent Resilience and Human Immunodeficiency Virus-acquired Immune Deficiency Syndrome Prevention Behavior: A Cross-sectional Study of Adolescents in DKI Jakarta Province, Indonesia

Background The incidence of human immunodeficiency virus (HIV)-acquired immune deficiency syndrome (AIDS) remains high in Indonesia. Therefore, HIV-AIDS prevention and control programs have been established for adolescents aged 15–24 years based on the United Nations Sustainable Development Goals. Internal risk factors related to risky sexual behavior and external risk factors associated with exposure to pornography through the media are major hurdles that need to be overcome in efforts to prevent HIV-AIDS among adolescents. Meanwhile, individual protective factors through self-control and adolescent resilience strongly impact the enhancement of HIV-AIDS prevention behavior. This study aimed to determine whether internal and external risk factors and individual and sociocultural protective factors exert influences on adolescent resilience and HIV-AIDS prevention behavior among adolescents. Methods This research employed a descriptive quantitative design with a cross-sectional approach. The population consisted of high school students aged 15–19 years in Jakarta, and a sample of 619 students was taken through proportional stratified random sampling. Inferential analysis was conducted using partial least squares structural equation modeling. Results The data analysis revealed that adolescent resilience (β-value = 0.423; t = 12.129), internal risk factors (β-value = 0.292; t = 10.903), and external risk factors (β-value = -0.088; t = 6.127) most significantly influenced HIV-AIDS prevention behavior, with significant negative impacts. The sub-variable that most strongly determined the presence of HIV-AIDS prevention behavior (Y2) was self-control (λ = 0.983), and the one that did so most weakly was negative cognition (λ = 0.875). Conclusion Adolescent resilience is a crucial factor in enhancing HIV-AIDS prevention behavior among adolescents as it influences adolescents’ beliefs, boosts their self-confidence, fosters emotional insight, and develops social skills and empathy toward others. Thus, enhancing it through HIV-AIDS prevention programs is essential.

Pituitary apoplexy is associated with concurrent or subsequent diagnosis of human immunodeficiency virus

AbstractObjectivePituitary apoplexy (PA) is a rare condition caused by hemorrhage or infarction of the pituitary gland with associated risk of cranial neuropathies, endocrinopathies, and even death. Human immunodeficiency virus (HIV) has been shown to have some association with pituitary apoplexy, however, large‐scale studies have not been performed.MethodsA retrospective cohort study of subjects greater than 18 years of age was performed using the national TriNetX database. The general population was first compared with those undergoing treatment for PA to compare general demographics and incidence of HIV. The PA cohort was then substratified by HIV status and propensity matched by age and sex to evaluate differences in visual outcomes and endocrine metrics. Using the diagnosis of pituitary apoplexy as an index event, the rate of HIV diagnosis at the time of presentation or in the three months following treatment was calculated. Two‐tailed, unpaired t‐tests were performed.ResultsA total 2066 patients were identified (902 HIV, 1158 controls). Those with HIV showed an increased rate of pituitary apoplexy (odds ratio [OR]: 19.8) versus healthy adults and were more likely to be younger and male. Among patients treated for pituitary apoplexy, patients with HIV were more likely to have increased thyroid stimulating hormone, reduced T4, and increased prolactin compared with healthy controls. There were no significant differences in visual outcomes between HIV positive and control patients. Importantly, 74% of patients did not carry a diagnosis of HIV on presentation but were diagnosed at the time of or in the three months following treatment for pituitary apoplexy.ConclusionsDiagnosis and treatment of pituitary apoplexy shows a high rate of concurrent or subsequent diagnosis of HIV. Screening for HIV should be considered in patients undergoing treatment for pituitary apoplexy.

Sources of Human Immunodeficiency Virus Infections Among Men Who Have Sex With Men With a Migration Background: A Viral Phylogenetic Case Study in Amsterdam, The Netherlands.

Men and women with a migration background comprise an increasing proportion of incident human immunodeficiency virus (HIV) cases across Western Europe. To characterize sources of transmission in local transmission chains, we used partial HIV consensus sequences with linked demographic and clinical data from the opt-out AIDS Therapy Evaluation in the Netherlands (ATHENA) cohort of people with HIV in the Netherlands and identified phylogenetically and epidemiologically possible HIV transmission pairs in Amsterdam. We interpreted these in the context of estimated infection dates, and quantified population-level sources of transmission to foreign-born and Dutch-born Amsterdam men who have sex with men (MSM) within Amsterdam transmission chains. We estimate that Dutch-born MSM were the predominant sources of infections among all Amsterdam MSM who acquired their infection locally in 2010-2021, and among almost all foreign-born Amsterdam MSM subpopulations. Stratifying by 2-year intervals indicated time trends in transmission dynamics, with a majority of infections originating from foreign-born MSM since 2016, although uncertainty ranges remained wide. Native-born MSM have predominantly driven HIV transmissions in Amsterdam in 2010-2021. However, in the context of rapidly declining incidence in Amsterdam, the contribution from foreign-born MSM living in Amsterdam is increasing, with some evidence that most local transmissions have been from foreign-born Amsterdam MSM since 2016.

Trends in Incidence of HIV and Syphilis Among Men Who Have Sex with Men - Tianjin Municipality, China, 2013-2022.

Given the common modes of transmission, outbreaks of both human immunodeficiency virus (HIV) and syphilis are primarily observed in men who have sex with men (MSM). However, minimal research has been conducted to concurrently evaluate the rates and trends of HIV and syphilis incidence within this community in China. This manuscript presents the incidence rates and associated factors of HIV and syphilis in MSM in Tianjin based on data derived from a decade-long cohort study. Intriguingly, it depicts a decreasing trend in HIV incidence juxtaposed with an increasing incidence of syphilis among this population in Tianjin. The interconnected risk factors for HIV and syphilis pose significant hindrances to disease control. Our study underscores the urgent need for improved intervention strategies specifically aimed at MSM to mitigate the propagation of both infections.

A 13-Year Trend Analysis of HIV Epidemiology in the Philippines (2010 to 2022)

ABSTRACT Purpose This article describes the trends and contributing factors in the human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS) epidemiology in the Philippines from 2010 to 2022. This is the first trend analysis of the Philippine HIV/AIDS situation. Design Using time trend research design, 13-year longitudinal epidemiological data were collected and analyzed to present a dynamic perspective of the Philippine HIV/AIDS epidemic. Methods Secondary data analysis of HIV surveillance public documents from 2010 to 2022 was conducted. The Centers for Disease Control’s socioecological model was used to guide the literature and interpretation of findings. Frequency, percentage distribution, and Sieve-bootstrap t-test for linear trends were used to analyze the results. Findings There is an increased trend in HIV incidence, late diagnosis, and AIDS-related mortality in all geographical regions in the country from 2010–2022. The majority of HIV cases are males, ages 25–34, and reside in the nation’s capital. Increased HIV incidence among overseas workers, sex workers, and HIV-positive blood products were noted. Conclusion Trends in Philippine HIV epidemiology are contrary to global trends. Community-based HIV prevention programs targeting specific high-risk populations are needed. Clinical Evidence Community health nurses in the Philippines play a critical role in reversing the rising trend of HIV/AIDS. They are positioned to lead targeted education and prevention programs for high-risk groups using the socioecological model to implement community-based strategies that address factors contributing to the epidemic. Their efforts in early detection and linkage to care are essential in reducing late diagnosis and AIDS-related mortality.

Modeling the HIV epidemic in MSM in Cyprus: reaching only the 95-95-95 cascade of care targets fails to reduce HIV incidence by 90% in 2030

ABSTRACT National responses should be improved and accelerated to meet the target of ending the Acquired ImmunoDeficiency Syndrome (AIDS) epidemic by 2030. In the Republic of Cyprus, Men who have Sex with Men (MSM) are disproportionately affected by Human Immunodeficiency Virus (HIV), accounting approximately for half of all annual HIV diagnoses. This study assesses the evolution of HIV incidence in MSM in Cyprus until 2030 using a model calibrated to Cypriot epidemiological data. Four scenarios were examined: status quo, two scenarios focusing on introducing Pre-Exposure Prophylaxis (PrEP), and a 90% HIV incidence reduction scenario. Reaching only the 95-95-95 HIV cascade of care targets among MSM would reduce HIV incidence by 48.6% by 2030 compared to 2015. Initiating a PrEP intervention only for high risk MSM would cause a modest further reduction in HIV incidence. To meet the 90% reduction target, PrEP should be expanded to both high and medium risk MSM and, after 2025, behavioral interventions should be implemented so as high-risk MSM gradually move to the medium-risk category. Cyprus will not reach the HIV incidence reduction target by 2030 unless PrEP is gradually promoted and delivered to all high and medium risk MSM along with awareness and behavioral interventions.

Trends in the burden and determinants of HIV in the Asia-Pacific region (1990-2019): An age-period-cohort analysis of the 2019 Global Burden of Disease Study.

Although the burden of the human immunodeficiency virus (HIV) in the Asia-Pacific region is increasingly severe, comprehensive evidence of the burden of HIV is scarce. We aimed to report the burden of HIV in people aged 15-79 years from 1990 to 2019 using data from the Global Burden of Disease Study (GBD) 2019. We analyzed rates of age-standardized disability-adjusted life years (ASDR), age-standardized mortality (ASMR), and age-standardized incidence (ASIR) in our age-period-cohort analysis by sociodemographic index (SDI). According to HIV reports in 2019 from 29 countries in the Asia-Pacific region, the low SDI group in Papua New Guinea had the highest ASDR, ASMR, and ASIR. From 1990 to 2019, the ASDR, ASIR, and ASMR of persons with acquired immune deficiency syndrome (AIDS) increased in 21 (72%) of the 29 countries in the Asia-Pacific region. During the same period, the disability-adjusted life years (DALYs) of AIDS patients in the low SDI group in the region grew the fastest, particularly in Nepal. The incidence of HIV among individuals aged 20-30 years in the low-middle SDI group was higher than that of those in the other age groups. In 2019, unsafe sex was the main cause of HIV-related ASDR in the region's 29 countries, followed by drug use. The severity of the burden of HIV/AIDS in the Asia-Pacific region is increasing, especially among low SDI groups. Specific public health policies should be formulated based on the socioeconomic development level of each country to alleviate the burden of HIV/AIDS.

Dolutegravir induces FOLR1 expression during brain organoid development.

During the first month of pregnancy, the brain and spinal cord are formed through a process called neurulation. However, this process can be altered by low serum levels of folic acid, environmental factors, or genetic predispositions. In 2018, a surveillance study in Botswana, a country with a high incidence of human immunodeficiency virus (HIV) and lacking mandatory food folate fortification programs, found that newborns whose mothers were taking dolutegravir (DTG) during the first trimester of pregnancy had an increased risk of neural tube defects (NTDs). As a result, the World Health Organization and the U.S. Food and Drug Administration have issued guidelines emphasizing the potential risks associated with the use of DTG-based antiretroviral therapies during pregnancy. To elucidate the potential mechanisms underlying the DTG-induced NTDs, we sought to assess the potential neurotoxicity of DTG in stem cell-derived brain organoids. The gene expression of brain organoids developed in the presence of DTG was analyzed by RNA sequencing, Optical Coherence Tomography (OCT), Optical Coherence Elastography (OCE), and Brillouin microscopy. The sequencing data shows that DTG induces the expression of the folate receptor (FOLR1) and modifies the expression of genes required for neurogenesis. The Brillouin frequency shift observed at the surface of DTG-exposed brain organoids indicates an increase in superficial tissue stiffness. In contrast, reverberant OCE measurements indicate decreased organoid volumes and internal stiffness.

Approaches for prevention of mother-to-child transmission of HIV services during coronavirus disease 2019.

During the coronavirus disease 2019 (COVID-19) pandemic, there was a reduction in access to prevention of mother-to-child transmission (PMTCT) of human Immunodeficiency virus (HIV) services globally, yet this programme is critical for reducing paediatric HIV incidence. To minimise the impact of COVID-19 and prevent disruptions to the PMTCT service provision, innovative strategies had to be developed and implemented. The study aimed to describe the approaches that were developed and utilised during the COVID-19 pandemic in enhancing PMTCT services in Tshwane primary healthcare facilities. Three primary healthcare facilities that were providing PMTCT services during the COVID-19 pandemic located in the Tshwane district, Gauteng province, South Africa. The study is part of a larger study that focused on the experiences of healthcare workers who were rendering PMTCT services during the COVID-19 pandemic. An interpretative phenomenological analysis (IPA) design was employed to gain insight into the experiences of 16 purposively sampled healthcare workers who were providing PMTCT services during the pandemic in Tshwane district facilities. In-depth individual audio-recorded interviews were conducted with study participants, following a semi-structured interview guide. Data analysis was performed using an IPA framework. Three superordinate themes emerged: strategies utilised for providing care, community-based initiatives, and support systems to enhance the PMTCT service access. Strengthening community-based initiatives and support systems is important for the enhancement of the PMTCT programme during and beyond the pandemic. Community-based initiatives are critical in continuity of PMTCT services, reducing HIV incidence, under-five child morbidity and mortality particularly during emergency situations.
