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.

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

Background: 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.Aim: 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.Settings: Three primary healthcare facilities that were providing PMTCT services during the COVID-19 pandemic located in the Tshwane district, Gauteng province, South Africa.Methods: 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.Results: Three superordinate themes emerged: strategies utilised for providing care, community-based initiatives, and support systems to enhance the PMTCT service access.Conclusion: Strengthening community-based initiatives and support systems is important for the enhancement of the PMTCT programme during and beyond the pandemic.Contribution: Community-based initiatives are critical in continuity of PMTCT services, reducing HIV incidence, under-five child morbidity and mortality particularly during emergency situations.

Relationship Between High ACE Score, HIV Risk Behavior, and Previous HIV Testing in the South Carolina BRFSS [ID 2683384

INTRODUCTION: The incidence of human immunodeficiency virus (HIV) in the United States is stable among women. Due to stigma, 13% of persons with HIV are unaware of their diagnosis. Adverse childhood experiences (ACEs) describe negative events during childhood using a standardized questionnaire. Limited data exist on how ACEs affect HIV screening. Utilizing state-collected data from the Behavioral Risk Factor Surveillance System (BRFSS), we assessed the relationships between high ACE, gender, HIV risk behaviors, and previous HIV testing. METHODS: This is a retrospective observational cohort study of the BRFSS from 2014–2016 and 2019–2021. High ACE score was ≥ 4. Using bivariate analyses, we compared percentages of individuals with high versus low ACE scores. We used logistic regression to determine factors associated with HIV risk behaviors and previous HIV testing. RESULTS: Over 54,000 individuals were surveyed; 15% had high ACE scores. 4% reported HIV risk behaviors and 35% reported previous HIV testing. The mean ACE was 1.6 (SD 2.1). High ACE demonstrated increased risk of HIV risk behaviors (adjusted odds ratio [aOR] 2.652; 95% CI, 1.987–3.538) and previous HIV testing (aOR 2.340; 95% CI, 2.031–2.696). Female respondents were less likely to report HIV risk behavior (aOR 0.442; 95% CI, 0.336–0.581) and previous HIV testing (aOR 0.822; 95% CI, 0.736–0.919). CONCLUSION: Persons with high ACE scores were more likely to engage in HIV risk behaviors and have a history of HIV testing. Our findings suggest ACE scores may be useful for identifying persons at risk for HIV. The stable incidence of HIV and reduced perception of risk among women demonstrate the need for tailored HIV screening for women.

Description Of The Usage Of Antiretroviral Medicine With Atc/Ddd Method In The Primary Health Care Centers Of Kediri 2021

AIDS (Acquired Immune Deficiency Syndrome) is a collection of symptoms and infections caused by damage to the human immune system, HIV (Human Immunodeficiency Virus ), a virus that can weaken human immunity. PLWHA patients must undergo antiretroviral virus (ARV) drug therapy, one of the drug use analysis classification systems is using the ATC/DDD system which is a means of researching drug use in an effort to improve the quality of drug use, one of these components is the presentation and comparison of drug consumption levels. international. The aim of this research is to determine the use of antiretroviral drug consumption in primary health care center in the Kediri City area for the 2021 period using the Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) method. The design of this research is quantitative descriptive, namely describing a particular event systematically and accurately and the treatment of this research is the process of collecting data and evaluating the use of antiretroviral drugs as well as verifying Primary health care center data by interviewing primary health care center pharmacists in the Kediri city area in 2021. Consumption of antiretroviral drugs (ARVs). ) is highest in the Campurejo primary health care center, namely Lamivudine (3TC) as much as 31.71%, Balowerti in primary health care center with Zidovudine (AZT) as much as 29.02% and Pesantren 1 primary health care center with the drug Nevirapine (NVP) as much as 32.62%, while the use of ARV drugs is low. At the Campurejo primary health care center, it was 0.0002% of the drug Dolutegravir (DTG), and at the Balowerti primary health care center, it was 0.0012% of the drug Dolutegravir (DTG), then at Pesantren 1 primary health care center , it was 0.0015% of the drug Dolutegravir (DTG). The incidence of HIV is still high in Indonesia, especially in the city of Kediri.

Uptake and challenges with daily oral pre-exposure prophylaxis among men who have sex with men and transgender women, suburban Yangon, Myanmar.

Pre-exposure prophylaxis (PrEP) is effective for human immunodeficiency virus (HIV) prevention in risk groups. We assessed PrEP uptake and 12-month retention among men who have sex with men (MSM) and transgender women (TGW) in Myanmar during the coronavirus disease 2019 pandemic and a political crisis. Using prospectively collected data, we assessed the proportion of persons eligible, initiated and retained 12months on PrEP. We calculated HIV and syphilis incidence among those initiated on PrEP. Predictors of compliance to scheduled visits were assessed with fractional logistic regression. Among 652 persons screened between July and December 2020, 85.3% were eligible and 38.8% initiated PrEP. The daily pill burden was the main reason (86.5%) for refusing PrEP. A history of HIV post-exposure prophylaxis (PEP) and having an HIV-positive partner not on anti-retroviral therapy (ART) was associated with PrEP uptake (p<0.05). The 12-month retention among those initiating PrEP was 43.0%. Age ≥25y, a history of PEP and having an HIV-positive partner not on ART predicted better compliance with scheduled visits (p<0.05). HIV incidence among PrEP initiators was 3.1 per 100 person-years (95% confidence interval [CI] 1.3 to 7.4) and syphilis incidence was 17.6 per 100 person-years (95% CI 12.3 to 25.1). A PrEP program for MSM and TGW in Myanmar was implemented successfully under difficult circumstances. Alternative strategies are needed addressing PrEP uptake and retention.

Self-Perception of Risk for HIV Acquisition and Calculated Risk for HIV Acquisition Among Active Duty Air Force Members With Newly Diagnosed HIV Infection.

There have been nearly 1,600 new diagnoses of Human Immunodeficiency Virus (HIV) across the US Armed Forces between 2017 and 2022. While treatment has improved overall survival, self-perception of acquiring HIV may not align with actual risk of acquiring HIV, thus slowing diagnosis and treatment. We aim to evaluate self-perceived risk (SPR) versus calculated risk (CR) of HIV infection in US Air Force (USAF) members with incident HIV diagnosis. All USAF members with new HIV diagnosis evaluated at a specialty care military medical center between January 2015 and March 2020 with case report forms were included (n = 142). SPR was compared to CR using the Denver HIV Risk Score (DHRS). The study was approved by the Army Public Health Center's Public Health Review Board (#14-311) and the Walter Reed Army Institute of Research Human Subjects Protection Branch (#1861E). Patients were predominantly male (98%), with a median age of 26 (IQR 22-30) years, and the majority (85%) reported same-sex partners. Most patients reported a low SPR (n = 78; 55%). A higher proportion of low SPR patients were married or partnered than high SPR patients (29% versus 14%; P = 0.04). Both groups had median DHRS scores in the highest risk category with similar results by reason for HIV screening. The majority of USAF members with incident HIV infection reported a low SPR despite risk factors and CRs identical to high SPR patients. In order to inform HIV prevention strategies in the military, further efforts are needed to educate the military population and providers about HIV risk perception.

Development and validation of the information-motivation-behavioural skills model-based human immunodeficiency virus education kit for adolescents in Malaysia

The growing Human Immunodeficiency Virus (HIV) incidences and insufficient HIV knowledge among Malaysian late adolescents necessitate immediate attention to HIV prevention via education. This study aims to develop and validate an Information-Motivation-Behavioural skills (IMB) model-based education kit for adolescents, PREM-Kit, to educate on HIV prevention among Malaysian late adolescents. Utilizing the Analysis, Design, Development, Implementation, and Evaluation model, we conducted the study in three phases: needs assessment, development of PREM-Kit, and validation of PREM-Kit by applying the IMB model to map the PREM-Kit’s contents. PREM-Kit, developed in Malay language, consisted of an infographic flip chart and videos. Five multi-disciplinary experts validated the PREM-Kit using the content validity index (CVI), and 13 end-users validated the PREM-Kit using the Malay version of the Patient Education Materials Assessment Tool for Printable and Audiovisual Materials. The infographic flip chart comprised three modules covering 15 topics, and an animated video accompanied each module. PREM-Kit achieved CVI scores of 1.0 and median scores of over 80% for understandability and actionability. Overall, the newly developed IMB model-based HIV education kit has good content validity, is simple to comprehend and apply, and is ready for testing its effectiveness in improving adolescents’ knowledge, attitudes, and practices for HIV prevention.

Effectiveness of human immunodeficiency virus prevention strategies by mapping the geographic dispersion pattern of human immunodeficiency virus prevalence in Nanning, China

BackgroundThe Guangxi government initiated two rounds of the Guangxi AIDS Conquering Project (GACP) in 2010 (Phase I) and 2015 (Phase II) to control human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemics. However, the effectiveness of GACP in HIV prevention and treatment has rarely been reported. This study aimed to assess the effectiveness of the GACP implemented in Guangxi, China and provide data for strategy and praxis improvements to achieve Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95 targets.MethodsWe used spatial approaches to trace the spatiotemporal distribution properties, epidemic trends, and correlation between macroscopic factors and HIV incidence using data from the Chinese HIV/AIDS case reporting system to explore the effects of the GACP.ResultsDuring the GACP era, the HIV epidemic stabilized in urban centers, showing a downward trend in the Hengzhou and Binyang Counties in the eastern region, whereas it continued to increase in rural areas of the northwest region, such as the Long’an, Mashan, Shanglin, and Wuming Districts. The linear directional mean (LDM) of HIV infection reported cases displayed a southeast–northwest direction, with an LDM value of 12.52°. Compared with that in Phase I, Hengzhou withdrew from the high-high clustering area, and the west–north suburban counties pulled out the low-low clustering area during Phase II. Significant HIV clusters were identified in the eastern region during Phase I, whereas these clusters emerged in the northwestern areas during Phase II. Regarding HIV, socioeconomic status, population mobility, and medical care levels were the key social drivers of heterogeneous spatial distribution.ConclusionsThe GACP assisted in effectively managing the HIV epidemic in urban and eastern areas of Nanning City. However, prevention and control efforts in rural regions, particularly those located in the northwest, may not have yielded comparable outcomes. To address this disparity, allocating additional resources and implementing tailored intervention measures for these rural areas are imperative.

Prevention and infection control of HIV infection and AIDS

Background: Although the global incidence of human immunodeficiency virus (HIV) has decreased significantly since modern antiretroviral therapy (ART), new HIV infections steadily occur, in the Republic of Korea. Based on the understanding of the risk factors for HIV infection, combined strategic behavioral and biomedical interventions should be implemented to reduce HIV infection. This paper reviews the strategies for the prevention of HIV infection.Current Concepts: While the consistent use of latex condoms is effective for the prevention of HIV transmission, consistent use of condoms is low among sexually active individuals. ART can be initiated, after exposure, to prevent HIV infection (post-exposure prophylaxis) after occupational or sexual exposure, injection drug use, and other nonoccupational exposures to HIV. There is a negligible risk of sexual transmission of HIV when the HIV-infected sexual partner has durably suppressed viral replication with ART. Antiretroviral agents have been shown to be highly effective when administered prophylactically to HIV-uninfected but at-risk individuals (preexposure prophylaxis). A high-risk group, such as men who have sex with men, is required to be included in health insurance care benefits for pre-exposure prophylaxis, in addition to the current partners of HIV-infected individuals, to ensure its efficacy.Discussion and Conclusion: HIV-related deaths are rapidly decreasing, but new HIV infections continue to occur. In an environment where a cure or the development of vaccines is unlikely, a multifaceted and proactive approach is required to minimize new HIV infections.

Comprehensive knowledge about HIV/AIDS and associated factors among reproductive age women in Liberia

IntroductionAcquired Immune Deficiency Syndrome (AIDS) continues to be a deadly pandemic and a serious threat to public health. Globally, reproductive age women are more likely to be infected with Human Immunodeficiency Virus (HIV). Comprehensive knowledge about HIV/AIDS is pivotal in the fight against AIDS. However, comprehensive HIV/AIDS knowledge is low in Sub-Saharan African (SSA) nations including Liberia, which contributes to the high incidence of HIV in these nations. This study assessed the level of comprehensive knowledge about HIV/AIDS and its associated factors among reproductive age women in Liberia.MethodsThe prevalence and associated factors of comprehensive knowledge about HIV/AIDS among reproductive age women in Liberia were determined using secondary data analysis of 2019–2020 Liberia Demographic and Health Surveys (LDHS). Comprehensive knowledge about HIV/AIDS was a composite variable computed from six variables available in the Demographic and Health Survey (DHS). The study included 7,621 reproductive age women in weighted samples. A generalized linear mixed model with robust error variance was used. For the variables included in the final model, adjusted prevalence ratios (aPR) with 95% confidence intervals (CI) were calculated.ResultsThe prevalence of comprehensive HIV/AIDS knowledge among Liberian women aged 15–49 was 33.5%. Women’s age and education, and distance to health facility were positively associated with comprehensive knowledge about HIV/AIDS among Liberian reproductive age women. In contrast, community poverty level was negatively associated with comprehensive knowledge about HIV/AIDS.Conclusion and recommendationsThis study demonstrates that the prevalence of good comprehensive HIV/AIDS knowledge was relatively low among reproductive age women in Liberia. Hence, health practitioners and policymakers should strengthen HIV/AIDS sensitization programmes to increase women’s knowledge about HIV/AIDS.

A Retrospective Study of the Presentation and Management of Perianal Disease in HIV-Positive Patients Referred to a Surgical Outpatient Unit in Turkey.

BACKGROUND The incidence of human immunodeficiency virus (HIV) infection is on the rise, and perianal region diseases in HIV-infected patients have become increasingly prevalent. This study aimed to analyze the surgical treatment outcomes of HIV-infected patients presenting with perianal concerns. MATERIAL AND METHODS We included 311 HIV-positive patients admitted to the Infectious Diseases Clinic of Samsun Training and Research Hospital between January 2014 and December 2022. From this group, we selected those who sought care at the general surgery outpatient clinic for perianal and anal concerns, retrospectively reviewing their medical records. RESULTS Out of 311 patients, 54 (17.3%) were referred to the general surgery outpatient clinic with anal and/or perianal region complaints. Of these cases, 38 (70.3%) had a single disease, while 16 (29.6%) had combined diseases. There were 20 males (95%) and 1 female (5%). Among these 54 patients, 33 (61.1%) received medical treatment from the outpatient clinic, while 21 (38.9%) underwent surgical intervention. The diagnoses included 22 hemorrhoidal diseases, 24 anal condylomas, 15 anal fissures, 11 anal abscesses, and 4 anal fistulas. We evaluated the postoperative results and recurrence status of these patients. CONCLUSIONS Perianal diseases in HIV-positive patients can be categorized as isolated or combined. The management of patients with postoperative follow-up compliance problems and combined diseases with low CD4 counts may pose treatment challenges.

Predictors of never testing for HIV among sexually active individuals aged 15–56 years in Rwanda

Human Immunodeficiency Virus (HIV) testing services are known as the primary step in preventing the spread of HIV. However, access to these crucial services varies across regions within continents due to disparities in healthcare infrastructure, resources, and awareness. Approximately one in every five people living with HIV (PLWH) encounters obstacles in accessing HIV testing, notably in Eastern and Southern Africa, where geographical, resource, awareness, and infrastructure limitations prevail. Consequently, HIV remains a significant public health concern in these regions, necessitating expanded testing efforts to combat the HIV/AIDS disaster. Despite these challenges, there is a lack of scientific evidence on the prevalence of HIV testing and its determining factors in Rwanda. This study determined the prevalence of never being tested for HIV and its associated factors among sexually active individuals aged 15–56 who participated in the Rwanda AIDS Indicators and HIV Incidence Survey (RAIHIS). This cross-sectional study enrolled 1846 participants. The variables were extracted from the RAIHIS dataset and statistically analyzed using STATA software version 13. Bivariate and multivariate logistic regression models were employed to identify predictors of never having undergone HIV testing, with a 95% confidence interval and a 5% statistical significance level applied. The prevalence of non-testing for HIV was 17.37%. Being aged 15–30 years (aOR 2.57, 95%CI 1.49–4.43, p < 0.001) and male (aOR 2.44, 95%CI 1.77–3.36, p < 0.001) was associated with an increase in the odds of never testing for HIV. Further, those from urban area were less likely than those living in rural areas to have never tested for HIV (aOR 0.31; 95% CI 0.38–0.67; p < 0.001). Participants who were not aware of HIV test facilitates were more likely to have never undergone HIV testing (aOR 1.75; 95% CI 1.25–2.47; p = 0.031) than their counterparts. While the prevalence of HIV non-testing remains modest, the significance of youth, male gender, lack of awareness, and rural residence as influential factors prompts a call for inventive strategies to tackle the reasons behind never having undergone HIV testing. Further exploration using mixed methodologies is advocated to better comprehend socio-cultural impacts and causation relating to these identified factors.

HIV incidence before and during the COVID-19 pandemic in Japan

&lt;abstract&gt; &lt;p&gt;At the end of 2022, a total of 20,003 diagnoses of human immunodeficiency virus (HIV) infection and 8,983 cases of acquired immunodeficiency syndrome (AIDS) among Japanese nationals, and 3,860 HIV diagnoses and 1,575 AIDS cases among foreign residents, had been notified to the government in Japan. This study updates the estimate of HIV incidence, including during the COVID-19 pandemic. It aimed to reconstruct the incidence of HIV and understand how the disruption caused by COVID-19 affected the epidemiology of HIV. Using a median incubation period of 10.0 years, the number of undiagnosed HIV infections was estimated to be 3,209 (95% confidence interval (CI): 2,642, 3,710) at the end of 2022. This figure has declined steadily over the past 10 years. Assuming that the median incubation period was 10.0 years, the proportion of diagnosed HIV infections, including surviving AIDS cases, was 89.3% (95% CI: 87.8%, 91.0%). When AIDS cases were excluded, the proportion was 86.2% (95% CI: 84.3%, 88.3%). During the COVID-19 pandemic, the estimated annual diagnosis rate was slightly lower than during earlier time intervals, at around 16.5% (95% CI: 14.9%, 18.1%). Japan may already have achieved diagnostic coverage of 90%, given its 9% increment in the diagnosed proportion during the past 5 years. The incidence of HIV infection continued to decrease even during the COVID-19 pandemic from 2020 to 2022, and the annual rate of diagnosis decreased slightly to 16.5%. Monitoring the recovery of diagnosis along with the effective reproduction number is vital in the future.&lt;/p&gt; &lt;/abstract&gt;

Evaluating the impact of triple elimination program for mother-to-child transmission of HIV, syphilis, and hepatitis B in Indonesia.

Indonesian government launched a triple elimination program to eliminate mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV), syphilis, and hepatitis B in 2018, aiming to increase screening uptake among pregnant women during antenatal visits and to reduce the rates of these infections in children less than 50 per 100,000 live births. Despite this initiative, a thorough assessment of its effectiveness, particularly in Bandung, the capital city of West Java, as one of the most densely populated cities in Indonesia with a high HIV incidence, has yet to be conducted. The aim of this study was to analyze the impact of this triple elimination program in Bandung by assessing the data between 2017 and 2020. Monthly data was obtained from the Health Office of Bandung for four years, including number of screenings done for HIV, syphilis, and hepatitis B, number of confirmed cases and number of pregnant women treated for those infections. Additionally, data on children under 24 months old afflicted by these infections were also collected. Our data indicated an increase in screening coverage for HIV, syphilis, and HBV among pregnant women; however, it remained below the national set benchmarks for screening coverage. Only 59.5% of HIV-positive pregnant women received anti-retroviral therapy in 2020, while merely 25% of syphilis-positive cases were administered benzathine penicillin G. Syphilis screening was correlated with an increase in positive cases among children, suggesting missed opportunities in managing syphilis-positive pregnant women. Furthermore, management of HIV- and syphilis-positive cases had suboptimal outcomes. Data on hepatitis B was not evaluated since it was not available. To achieve the triple elimination program goals, comprehensive coordination among all relevant stakeholders is required, as is continuous monitoring and evaluation.

Doxycycline Prophylaxis to Prevent Sexually Transmitted Infections in Women

BackgroundDoxycycline postexposure prophylaxis (PEP) has been shown to prevent sexually transmitted infections (STIs) among cisgender men and transgender women, but data from trials involving cisgender women are lacking.MethodsWe conducted a randomized, open-label trial comparing doxycycline PEP (doxycycline hyclate, 200 mg taken within 72 hours after condomless sex) with standard care among Kenyan women 18 to 30 years of age who were receiving preexposure prophylaxis against human immunodeficiency virus (HIV). The primary end point was any incident infection with Chlamydia trachomatis, Neisseria gonorrhoeae, or Treponema pallidum. Hair samples were collected quarterly for objective assessment of doxycycline use.ResultsA total of 449 participants underwent randomization; 224 were assigned to the doxycycline-PEP group and 225 to the standard-care group. Participants were followed quarterly over 12 months. A total of 109 incident STIs occurred (50 in the doxycycline-PEP group [25.1 per 100 person-years] and 59 in the standard-care group [29.0 per 100 person-years]), with no significant between-group difference in incidence (relative risk, 0.88; 95% confidence interval [CI], 0.60 to 1.29; P=0.51). Among the 109 incident STIs, chlamydia accounted for 85 (78.0%) (35 in the doxycycline-PEP group and 50 in the standard-care group; relative risk, 0.73; 95% CI, 0.47 to 1.13). No serious adverse events were considered by the trial investigators to be related to doxycycline, and there were no incident HIV infections. Among 50 randomly selected participants in the doxycycline-PEP group, doxycycline was detected in 58 of 200 hair samples (29.0%). All N. gonorrhoeae–positive isolates were resistant to doxycycline.ConclusionsAmong cisgender women, the incidence of STIs was not significantly lower with doxycycline PEP than with standard care. According to hair-sample analysis, the use of doxycycline PEP among those assigned to receive it was low. (Funded by the National Institutes of Health; dPEP ClinicalTrials.gov number, NCT04050540.)

Examination of Incidence of Sexually Transmitted Infections in the Ending the HIV Epidemic Priority Counties of the United States, 2005-2019.

The incidence of sexually transmitted infections (STIs) has been increasing in the United States, and this trend has continued alongside expanding/changing human immunodeficiency virus (HIV) prevention strategies, moving from reliance solely on behavioral interventions like condoms to biomedical methods like oral and injectable antiretroviral preexposure prophylaxis (PrEP). In 2019, the Ending the HIV Epidemic (EHE) initiative was released to prioritize resource allocation to the 50 jurisdictions in the United States with the highest HIV incidence, providing an opportunity to monitor STI incidence in a national group of discrete, geographic units and identify trends and differences across jurisdictions. Using existing data from the US CDC and Census Bureau, a retrospective analysis was conducted to examine the incidence of STIs in 49 of the 50 EHE priority counties between 2005 and 2019. This timeframe was divided into 2 periods representing a before and after entry into the biomedical era of HIV prevention: P1 (2005-2011) and P2 (2012-2019). A total of 49 EHE counties were included in this analysis, representing 27.4% of the total US population. Entry into the biomedical HIV prevention era was associated with an increase in STI incidence in 28 EHE counties and a decrease in 14 EHE counties. The greatest percent increase in total STI incidence was in the District of Columbia (+12.1%; incidence rate ratio = 1.121 [1.115, 1.127]; P < 0.001) and the greatest percent decrease was identified in Orleans Parish, LA (-8.7%; incidence rate ratio = 0.913 [0.908, 0.919]; P < 0.001). Rising STI rates in the biomedical era of HIV prevention represent missed opportunities for comprehensive sexual and preventive healthcare. County-level data provide actionable insight for reducing STI incidence. The EHE counties that have experienced decreases in STI incidence while being in the biomedical era may provide models of best practice, which may be scaled in other jurisdictions.

Spatial heterogeneity in relationship between district patterns of HIV incidence and covariates in Zimbabwe: a multi-scale geographically weighted regression analysis.

A study was conducted to investigate the district-level patterns of incidence of the human immunodeficiency virus (HIV) in Zimbabwe in the period 2005-2015 and explore variations in the relationship between covariates and HIV incidence across different districts. Demographic health survey data were analysed using hotspot analysis, spatial autocorrelation, and multi-scale geographically weighted regression (MGWR) techniques. The analysis revealed hotspots of the HIV epidemic in the southern and western regions of Zimbabwe in contrast to the eastern and northern regions. Specific districts in Matabeleland South and Matabeleland North provinces showed clusters of HIV incidence in 2005-2006, 2010-2011 and 2015. Variables studied were multiple sex partners and sexually transmitted infections (STI) condom use and being married. Recommendations include implementing targeted HIV prevention programmes in identified hotspots, prioritising interventions addressing the factors mentioned above as well as enhancing access to HIV testing and treatment services in high-risk areas, strengthening surveillance systems, and conducting further research to tailor interventions based on contextual factors. The study also emphasizes the need for regular monitoring and evaluation at the district level to inform effective responses to the HIV epidemic over time. By addressing the unique challenges and risk factors in different districts, significant progress can be made in reducing HIV transmission and improving health outcomes in Zimbabwe. These findings should be valuable for policymakers in resource allocation and designing evidence-based interventions.

Increase in human immunodeficiency virus and syphilis prevalence and incidence among men who have sex with men, vietnam 2015 - 2020.

We assessed trends in HIV and syphilis prevalence, HIV incidence, related risk factors, and preventive behaviors among men who have sex with men (MSM) in Vietnam from 2015 to 2020. Data originated from the HIV Sentinel Surveillance Plus system, which sampled MSM at venues and hotspots in seven of Vietnam's 63 provinces in 2015, 2016, 2018, and 2020 (N = 1100-1445 per year; ∼150-300 per province per year). HIV prevalence estimates increased from 6.6% (95% CI 4.5-9.6) in 2015 to 13.8% (95% CI 10.5-18.2, p = .001 for trend) in 2020 overall, and separately in An Giang, Can Tho, Hai Phong, and Khanh Hoa provinces but not in Ho Chi Minh City, Hanoi, or Kien Giang. Syphilis prevalence increased from 2.7% (95% CI 1.4-5.1) in 2015 to 12.6% (95% CI 8.7-18.0) in 2020 overall (p < .001 for trend), and separately in An Giang, Can Tho, and Hai Phong provinces but not in Ho Chi Minh City or Kien Giang. We calculated time-at-risk from first anal sex to first HIV-positive or last HIV-negative test to estimate HIV incidence. Estimated HIV incidence suggested increasing rates of seroconversion from 1.36 per 100 person-years experienced by participants in 2015 to 2.61 per 100 person-years among participants in 2020 (hazard ratio per year 1.13, 95% CI 1.08-1.18, p < .001). There was a statistically significant increase in HIV testing, STI testing, and receipt of free condoms over the period (p < .05 for trend), and a statistically significant decrease in amphetamine use (p = .043 for trend). Despite prevention efforts and improvements in some risk indicators, consecutive cross-sectional sampling results provide evidence of increasing incidence of HIV and syphilis among MSM in Vietnam, especially outside the major cities. Aggressive HIV prevention and treatment services can be expanded while conducting deeper investigations into the causes of these increases.

Demand creation and retention strategies for oral pre-exposure prophylaxis for HIV prevention among men who have sex with men and transgender women: a systematic review and meta-analysis

BackgroundMen who have sex with men (MSM) and transgender women (TGW) have a disproportionately higher risk of human immunodeficiency virus (HIV) infection than other groups. Oral HIV pre-exposure prophylaxis (PrEP) is an effective prevention tool and should be offered to those at higher risk. Identifying demand creation strategies (DCS) and retention strategies (RS) to improve PrEP persistence is essential to control the HIV epidemic.AimWe aimed to identify the (DCS and RS with higher proportions among MSM and TGW.MethodsA systematic review and meta-analysis of prospective studies were conducted, with studies retrieved from five databases until November, 2022 following the Cochrane and PRISMA guidelines. The study protocol was registered in PROSPERO (CRD42022323220). The outcomes were DCS and RS for PrEP use among MSM and TGW. Strategies used for users enrolled in the PrEP-recruited (DCS) were classified as face-to-face (peer educator recruitment at social venues, nongovernmental organizations, and parties; direct referrals by health services; friends and/or sexual partners); online (chatbot or peer educator recruitment on social media [e.g., , Instagram or Facebook] or dating/hook-up apps [e.g., Grindr, Tinder, Badoo, and Scruff]); and mixed (face-to-face and online). RS was classified as provider counseling (face-to-face by a health professional; prevention of HIV risk counseling, distribution of condoms, lubricants, and testing for HIV or other sexually transmitted infections); online counseling (text messages, chatbots, telephone calls, social media, and peer educators); and mixed (all previous strategies). Subgroup analyses were conducted for each treatment strategy. Meta-analyses were performed using the R software version 4.2.1.ResultsA total of 1, 129 studies were retrieved from the five databases. After eligibility, 46 studies were included. For MSM, most DCS and RS were online at 91% (95% CI: 0.85–0.97; I2=53%), and 83% (95% CI: 0.80–0.85; I2=17%) respectively. For TGW, mixed DCS and RS were the most frequent at85% (95% CI: 0.60–1.00; I2=91%) and online counseling at 84% (95% CI: 0.64–0.95) compared to other strategies.ConclusionCritical issues play. Pivotal role in increasing PrEP awareness among MSM and TGW, minimizing access gaps, and ensuring retention of PrEP services. Offering oral PrEP using online DCS and RS can reach and retain high numbers of MSM and TGW, and reduce HIV incidence in these populations.
