The Utilization of Contraceptives by Teenagers in Lesotho: A Descriptive Cross-Sectional Survey

<i>Background</i>: Contraceptive service provision to teenagers prevents pregnancy and childbirth complications, which are the leading causes of death among teenage girls globally. The study aimed to assess how teenagers utilized the contraceptive services provided at selected healthcare facilities in Lesotho. A quantitative descriptive cross-sectional design was used to collect data from 194 teenagers who were conveniently sampled from two health facilities in Berea district, Lesotho. Permission to conduct the study was sought and granted from the Ministry of Health and written informed consent was sought from the participants before they completed self-administered questionnaires. Data was captured and analyzed using the Statistical Package for the Social Science (SPSS) version 24. Most (64.5%) of the teenagers knew that contraceptives prevented pregnancy, whilst a fifth of them referred to them as the prevention of Human Immunodeficiency Virus (HIV) or sexually transmitted infections (STIs). Utilization of contraceptives was reported by just over a third and about two-fifths were able to access them at the public health clinics daily. Injectables and condoms were the most preferred methods used by teenagers. Factors that enhanced contraceptive usage included nurses’ friendliness, as well as an understanding of why teenagers are not fully utilizing the contraceptive services provided. Most teenagers were found not to be utilizing contraceptive services due to the belief that they led to weight gain and unsatisfactory intercourse. The study findings provided a need for and importance of contraceptive service provision to teenagers, including the need for education to improve their understanding and reduce myths. Hence, healthcare service providers need to improve access to contraceptive services to improve their utilization by teenagers.

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.

Meta-analysis of the effectiveness of educational programs about HIV prevention on knowledge, attitude, and behavior among adolescents.

The prevalence of human immunodeficiency virus (HIV) among adolescents is on the rise due to a lack of comprehensive knowledge, leading to suboptimal attitudes and behaviors, which emphasizes the critical need for targeted interventions. The aim of this review study was to evaluate the effectiveness of educational interventions for HIV prevention among adolescents by assessing their impact on knowledge, attitude, and behavior. A systematic review of seven databases: PubMed, Science Direct, Cochrane, JSTOR, Embase, Scopus, and EBSCO were identified, and 14 eligible randomized controlled trials published until June 2023 were included. Two independent authors assessed quality appraisal using the Risk of Bias 2.0. Outcomes were measured using the standard mean difference (SMD) with random effects model and a 95% confidence interval. Subgroup analyses and meta-regression were performed to explore heterogeneity. The results showed significant improvements in participants' knowledge (SMD: 1.13, 95%CI: 0.78-1.49), behavior intentions (SMD: 1.22, 95%CI: 0.37-2.07), and attitude (SMD: 0.48, 95%CI: 0.02-0.95) after receiving HIV prevention education programs. Interventions grounded in theoretical principles and incorporating technology, group settings, and audio-visual aids were found to be effective in enhancing knowledge of HIV prevention and promoting behavioral intentions. Peer-led education positively impacted both knowledge and attitude. Moreover, excluding parents from these programs was identified as a crucial factor in improving adolescents' knowledge of HIV prevention. In conclusion, educational programs focused on HIV effectively enhance adolescents' knowledge, attitudes, and behavioral intentions among adolescents. Professionals planning interventions should consider these impactful components in designing comprehensive strategies.

Knowledge, Practices and Attitude of Pregnant Women on Prevention and Transmission of HIV, Hepatitis B and C With Respect to Educational Level among Pregnant Women Visiting Health Centers at the Mifi Health District in Cameroon

Purpose: Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) , hepatitis C virus are causes of significant morbidity and mortality across the World .HIV and HBV&amp;HCV are blood-borne viruses transmitted usually through sexual contact and use of unsterilized needles. Their similar means of transmission increases the risk of contracting both infections concurrently. This study was aimed at assessing the knowledge, practices and attitude of pregnant women on prevention and transmission of HIV, hepatitis B and C with respect to educational level at the Mifi health district. Methodology: This study was a descriptive cross sectional study involving pregnant women who visited different health centers with the Mifi health district between the month of January to june 2023. Sampling was done by convenience Data was analysed using version 20.0. and the data was presented in tables and bar graphs, meanwhile the pearson chi square test was used to compare variables under investigation at a confidence interval of 95%, providing a 5% error margin. Descriptive values were expressed as the frequency, percentage, and mean ± standard deviation (SD). Findings: Out of the 467 participants, 80.73% were within the poor knowledge range whereas 12.63% showed good knowledge (while 6.63 recorded excellent knowledge scores. 44.96% were within the poor practice range while 55.03% showed good practice. majority showed poor attitude toward transmission and prevention of HIV, HBV and HCV as only 18(3.85%) were willing to meet the doctor if they were diagnosed of any of the above mention infections meaning 449 (96.14%) will embrace fear and sadness. Majority of pregnant women in this study had good knowledge regarding prevention and transmission of HIV,HBV and. Irrespective of the knowledge, practices and attitude of the participants were generally poor at the Mifi health district in Cameroon. Unique Contribution to Theory, Practice and Policy: This research have come to set standard in health facilities in the mifi health district by proving beyond doubt that pregnant women are co infected with both HIV,HBV, and HCV and giving the poor attitude and practices among women that fuel the transmissions of these infections, we stand to advocate that all women presenting for ANC, should be compulsorily tested for HIV,HBV and HCV and equally much education on the transmission mode of these infections by the nurses should be implemented. This study have saved as an eye opener to policy makers to impost the testing of HIV, HBV and HCV during every first ANC visit and possibly two weeks before delivery.

Knowledge about HIV and Stigmatizing Attitudes of Medical Students in Saudi Arabia Towards Patients with HIV/AIDS: A Cross-Sectional Nationwide Study.

The Human Immunodeficiency Virus (HIV) and the social stigma directed toward patients with HIV are serious public health issues. We aimed to evaluate the HIV knowledge base and stigmatizing attitudes toward patients with HIV among students enrolled in medical schools in Saudi Arabia. This cross-sectional study included students at medical colleges in Saudi Arabia and was conducted between February and March 2023. We used non-random convenience sampling with an online chain referral via a validated Arabic questionnaire composed of 35 questions. Data were analyzed using descriptive and comparative statistics. A total of 1,213 medical students (women: 56.6%) participated in the study. Students in clinical years had a higher level of HIV knowledge than their pre-clinical colleagues. Logistic regression analysis revealed that participants who gave incorrect answers to questions related to mother-to-child and casual contact HIV transmission had a higher likelihood of harboring a negative attitude towards patients with HIV. Conversely, those who correctly answered queries on prevention and treatment were less likely to have stigmatizing attitudes. A significant proportion of this cohort harbored negative attitudes toward patients with HIV, with the sex and geographic location of participants being significant predictors of negative attitudes. Our data have revealed a significant percentage of medical students in Saudi Arabia to have misconceptions about HIV transmission and prevention, and stigmatizing attitudes toward patients with HIV, indicating a need for targeted interventions to enhance the HIV knowledge base in this population of future caregivers.</p>.

Missed Opportunities for Preexposure Prophylaxis Initiation in Hospitalized Persons With Opioid Use Disorder and Infectious Diseases.

Hospitalizations are increasing among persons who use opioids, secondary to overdose and infections. Our study identified acute hospitalization as a reachable moment for engaging people who use drugs in increased screening and education about human immunodeficiency virus risk and prevention (preexposure prophylaxis).

Projecting the Potential Clinical and Economic Impact of Human Immunodeficiency Virus Prevention Resource Reallocation in Tennessee.

In 2023, Tennessee replaced $6.2 M in US Centers for Disease Control and Prevention (CDC) human immunodeficiency virus (HIV) prevention funding with state funds to redirect support away from men who have sex with men (MSM), transgender women (TGW), and heterosexual Black women (HSBW) and to prioritize instead first responders (FR), pregnant people (PP), and survivors of sex trafficking (SST). We used a simulation model of HIV disease to compare the clinical impact of Current, the present allocation of condoms, preexposure prophylaxis (PrEP), and HIV testing to CDC priority risk groups (MSM/TGW/HSBW); with Reallocation, funding instead increased HIV testing and linkage of Tennessee-determined priority populations (FR/PP/SST). Key model inputs included baseline condom use (45%-49%), PrEP provision (0.1%-8%), HIV testing frequency (every 2.5-4.8 years), and 30-day HIV care linkage (57%-65%). We assumed Reallocation would reduce condom use (-4%), PrEP provision (-26%), and HIV testing (-47%) in MSM/TGW/HSBW, whereas it would increase HIV testing among FR (+47%) and HIV care linkage (to 100%/90%) among PP/SST. Reallocation would lead to 166 additional HIV transmissions, 190 additional deaths, and 843 life-years lost over 10 years. HIV testing reductions were most influential in sensitivity analysis; even a 24% reduction would result in 287 more deaths compared to Current. With pessimistic assumptions, we projected 1359 additional HIV transmissions, 712 additional deaths, and 2778 life-years lost over 10 years. Redirecting HIV prevention funding in Tennessee would greatly harm CDC priority populations while conferring minimal benefits to new priority populations.

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.

Systemic delivery of bictegravir and tenofovir alafenamide using dissolving microneedles for HIV preexposure prophylaxis

Human immunodeficiency virus (HIV) continues to pose a serious threat to global health. Oral preexposure prophylaxis (PrEP), considered highly effective for HIV prevention, is the utilisation of antiretroviral (ARV) drugs before HIV exposure in high-risk uninfected individuals. However, ARV drugs are associated with poor patient compliance and pill fatigue due to their daily oral dosing. Therefore, an alternative strategy for drug delivery is required. In this work, two dissolving microneedle patches (MNs) containing either bictegravir (BIC) or tenofovir alafenamide (TAF) solid drug nanoparticles (SDNs) were developed for systemic delivery of a novel ARV regimen for potential HIV prevention. According to ex vivo skin deposition studies, approximately 11% and 50% of BIC and TAF was delivered using dissolving MNs, respectively. Pharmacokinetic studies in Sprague Dawley rats demonstrated that BIC MNs achieved a long-acting release profile, maintaining the relative plasma concentration above the 95% inhibitory concentration (IC95) for 3 weeks. For TAF MNs, a rapid release of drug and metabolism of TAF into TFV were obtained from the plasma samples. This work has shown that the proposed transdermal drug delivery platform could be potentially used as an alternative method to systemically deliver ARV drugs for HIV PrEP.

Navigating Barriers and Opportunities: Perceptions of the Non-Occupational Post-Exposure Prophylaxis Care Continuum Among Young Sexual Minority Men, Aged 17-24, in the United States.

Human immunodeficiency virus (HIV) is a public health concern among young sexual minority men (YSMM), ages 17 to 24, in the United States. Biomedical prevention methods, such as pre-exposure prophylaxis (PrEP) and non-occupational post-exposure prophylaxis (nPEP), can help reduce the risk of HIV transmission among this population. However, there is limited awareness and use of nPEP by YSMM. This study aims to explore the perceptions of YSMM regarding the nPEP care continuum, which consists of three areas of focus: awareness, uptake, and linkage to other HIV prevention services. This study draws on synchronous online focus groups with a sample of 41 YSMM in the United States. Transcripts from the focus groups were analyzed using reflexive thematic analysis. Participants reported limited nPEP awareness and prior use, a process of personal appraisal of nPEP need based on HIV risk and costs, and a preference for PrEP over PEP for long-term HIV prevention. Interventions should be tailored to increase awareness of nPEP among YSMM and reduce addressable barriers to nPEP use for YSMM, including cost and confidentiality concerns, in situations where nPEP is warranted. Finally, more research is needed on how nPEP use can act as a bridge to PrEP initiation for this population.

Climate change, flooding, and HIV transmission in Africa: Potential relationships and a call for action

AbstractThe increasing effects of climate change have intensified floods globally, especially in Africa, where millions of people live in poverty and are highly vulnerable to flooding. Climate change disproportionately affects the vulnerable, who are least equipped to handle its consequences, by exacerbating their situation. One such consequence is the potential for increased human immunodeficiency virus (HIV) transmission. Africa has been disproportionately affected by the HIV epidemic. It now faces the additional challenge of a changing climate and floods, which are capable of increasing HIV transmission in Africa through several pathways. They can force population displacement and migration, leading to the expansion of sexual networks among people living with HIV (PLWHIV). They may also create conditions conducive to the spread of other infections. Floods can cause food insecurity, which can result in various sexual behaviors that expose people to HIV infection. As global warming is linked to a decrease in African food production capacity, the effect of food insecurity on HIV may be prominent in countries where transactional sexual means is a major route of HIV transmission. Floods can also hinder the provision of HIV services, such as pre‐ and postexposure prophylaxis and antiretroviral therapy distribution, which may worsen the health outcomes of PLWHIV and promote HIV transmission, particularly in rural and remote communities. It is crucial to develop a climate‐resilient framework, including education, sustained access to HIV services, and promotion of social welfare for HIV prevention and treatment, to address the complex relationship between HIV, floods, and climate change.

Pre- and Post-Exposure Prophylaxis for HIV in Patients Taking Anti-Seizure Medications.

The prevention of human immunodeficiency virus (HIV) infection has recently emphasized the use of pre- and post-exposure prophylaxis (PrEP and PEP), both of which were highly effective in prevention of HIV infection. Since the last published guidance regarding the cotreatment of people with anti-seizure medications (ASM) and antiretroviral treatments (ARTs) in 2012, both fields have numerous new medication options. Historically, cotreatment of HIV and seizures could be challenging with increased risk of virologic failure and barriers in access to health care due to global availability, social determinants of health, and stigma of both HIV and seizures. In this narrative review, we describe the data-driven and expected bidirectional pharmacokinetic (PK) interactions between guideline-based PrEP and PEP treatment and ASM, as well as overlapping side effects. There are many ASMs with no known interaction with PrEP or PEP regimens. The interactions focus on enzyme inducing ASMs, valproate, and lamotrigine. Most prominently, enzyme inducing ASMs lower serum levels of tenofovir-containing PrEP regimens and elements of PEP (dolutegravir, raltegravir, and ritonavir), which increased risk of virologic treatment failure in people with HIV but have unclear clinical significance on the effectiveness of PrEP and PEP. In addition, ritonavir treatment in PEP may significantly lower lamotrigine serum levels even during the 4 weeks of treatment, which may increase risk for breakthrough seizures during PEP and skin reactions after discontinuation of ritonavir. In addition to PK interactions, overlapping side effects are common including osteopenia, hepatic toxicity, and other gastrointestinal effects. This narrative review aims to be a resource for all clinicians prescribing ASMs so that they can create a welcoming environment to enable successful treatment of seizures and reduce the risk of HIV infection in people at risk. In addition, we highlight knowledge gaps and areas of unmet need that can be addressed with future studies.

Novel DNA Biosensing Platform for Detecting HIV Integrase for Highly Sensitive and Quantitative HIV Detection, Diagnosis, and Therapeutic Monitoring.

Straightforward, sensitive, and specific human immunodeficiency virus (HIV) assays are urgently needed. The creation of a point-of-care (POC) device for decentralized diagnostics has the potential to significantly reduce the time to treatment, especially for infectious diseases. Notably, however, many POC solutions proposed to date fall short of meeting the ASSURED guidelines, which are crucial for effective deployment in the field. Herein, we developed a DNA biosensor platform for the specific and quantitative detection of HIV. The platform contains a rolling circle amplification (RCA)-based DNA biosensor and a portable fluorescence detector, in which HIV-encoded integrase (IN) enzyme activity is used as a biomarker to achieve HIV-specific detection. The cleavage and integration reaction of IN on the sensor surface and RCA are combined in this detection platform to perform detection signal cascade amplification, ultimately achieving a detection limit of 0.125 CFU/μL of HIV particles. Moreover, the DNA sensor system exhibited high sensitivity and accuracy for detecting HIV in clinical samples, suggesting that it has potential for application in clinical settings to detect retroviruses other than HIV. In addition, quantitative detection based on this biosensing platform was significantly correlated with the CD4+ lymphocytes count, which can provide guidance for antiretroviral therapy and which affects long-term death risk assessment in HIV patients. Therefore, this DNA biosensing platform based on IN activity is expected to be useful for rapid HIV testing, diagnosis, and treatment monitoring, enabling the development of new POC diagnostic tests and will thus be highly valuable for developing HIV prevention strategies and effective treatments.

Effectiveness of eHealth interventions for HIV prevention, testing and management: An umbrella review.

Human immunodeficiency virus (HIV) infection has become a major contributor to the global burden of disease. Globally, the number of cases of HIV continues to increase. Electronic health (eHealth) interventions have emerged as promising tools to support disease self-management among people living with HIV. The purpose of this umbrella review is to systematically evaluate and summarize the evidence and results of published systematic reviews and meta-analyses on the effectiveness of eHealth interventions for HIV prevention, testing and management. PubMed, Embase and the Cochrane Library were searched for reviews. The methodological quality of the included studies was assessed using AMSTAR-2. A total of 22 systematic reviews were included. The methodological quality of the reviews was low or critically low. EHealth interventions range from Internet, computer, or mobile interventions to websites, programs, applications, email, video, games, telemedicine, texting, and social media, or a combination of them. The majority of the reviews showed evidence of effectiveness (including increased participation in HIV management behaviours, successfully changed HIV testing behaviours, and reduced risk behaviours). EHealth interventions were effective in the short term. Ehealth interventions have the potential to improve HIV prevention, HIV testing and disease management. Due to the limitations of the low methodological quality of the currently available systematic reviews, more high-quality evidence is needed to develop clear and robust recommendations.

Factors affecting HIV prevention communication between professional nurses and high school learners in eThekwini.

Communication within healthcare settings is crucial for a therapeutic relationship between nurse and patient especially in preventing human immunodeficiency virus (HIV) among adolescent girls. The school health programme in South Africa provides an opportunity to provide HIV prevention services among adolescent girls, however, uptake is low and effective communication can address this. The study's purpose was to describe factors affecting HIV prevention communication between professional nurses and high school learners in eThekwini Metropolitan Municipality. The study was conducted in two high schools in eThekwini Metropolitan Municipality. The study used a qualitative approach and a descriptive research design. A semi-structured interview guide was used to conduct face-to-face interviews with 30 participants after ethical approval from the researchers' affiliated institution and informed consent from participants or their guardians were obtained. Thematic analysis was used to analyse the data. Participants were aged between 14 years and 17 years. Most (25) participants were female. Three main themes emerged from the study: communication between the school health nurses and high school learners is facilitated by trust, communication is hindered by fear, and infrequent visits by nurses affect communication positively or negatively. Health education on HIV is essential to prevent HIV among adolescent girls. Effective communication between healthcare providers and adolescent girls facilitates such health education. The uptake of HIV prevention services by adolescent girls can be improved by communication that facilitates the therapeutic relationship which is founded on trust, with frequent visits by nurses.

Broadly neutralizing antibodies for HIV prevention: a comprehensive review and future perspectives.

SUMMARYThe human immunodeficiency virus (HIV) epidemic remains a formidable global health concern, with 39 million people living with the virus and 1.3 million new infections reported in 2022. Despite anti-retroviral therapy's effectiveness in pre-exposure prophylaxis, its global adoption is limited. Broadly neutralizing antibodies (bNAbs) offer an alternative strategy for HIV prevention through passive immunization. Historically, passive immunization has been efficacious in the treatment of various diseases ranging from oncology to infectious diseases. Early clinical trials suggest bNAbs are safe, tolerable, and capable of reducing HIV RNA levels. Although challenges such as bNAb resistance have been noted in phase I trials, ongoing research aims to assess the additive or synergistic benefits of combining multiple bNAbs. Researchers are exploring bispecific and trispecific antibodies, and fragment crystallizable region modifications to augment antibody efficacy and half-life. Moreover, the potential of other antibody isotypes like IgG3 and IgA is under investigation. While promising, the application of bNAbs faces economic and logistical barriers. High manufacturing costs, particularly in resource-limited settings, and logistical challenges like cold-chain requirements pose obstacles. Preliminary studies suggest cost-effectiveness, although this is contingent on various factors like efficacy and distribution. Technological advancements and strategic partnerships may mitigate some challenges, but issues like molecular aggregation remain. The World Health Organization has provided preferred product characteristics for bNAbs, focusing on optimizing their efficacy, safety, and accessibility. The integration of bNAbs in HIV prophylaxis necessitates a multi-faceted approach, considering economic, logistical, and scientific variables. This review comprehensively covers the historical context, current advancements, and future avenues of bNAbs in HIV prevention.

The Global Impact of HIV: A Comprehensive Review

The Human Immunodeficiency Virus (HIV) has been a significant global health challenge since its discovery in the 1980s, leading to the devastating Acquired Immunodeficiency Syndrome (AIDS). Despite advancements in medical research and antiretroviral therapies, HIV/AIDS remains a pressing public health concern, particularly in resource-limited regions. This comprehensive review provides updated data and scientific insights on the global impact of HIV, shedding light on the current state of the epidemic and the challenges faced in combating it. The review highlights the resurgence of HIV cases in Eastern European countries, such as Ukraine, Estonia, and Latvia, with surprising increases in AIDS cases observed in East Asian countries. However, it is in sub-Saharan Africa that the burden of HIV remains most acute, with high prevalence rates and a significant number of affected individuals. The region requires continued attention and resources to address the complex challenges associated with HIV prevention, treatment, and care. The article delves into the classification and structure of HIV, emphasizing its belonging to the Lentivirinae subfamily, specifically HIV-1 and HIV-2. HIV-1, the predominant viral species globally, exhibits a distinct clinical latency phase, contributing to its persistence and infectivity. The high replication rate and genetic variability of HIV, driven by the error-prone reverse transcriptase enzyme, result in the emergence of diverse subtypes and strains across different regions. Furthermore, the article explores the structural components of HIV-1, including the envelope glycoproteins (gp120 and gp41), matrix protein, and various enzymes critical to the viral life cycle. Despite progress in medical research and access to antiretroviral therapies, HIV/AIDS continues to present challenges such as limited resources, drug resistance, and regional disparities.

Facilitators, Barriers, and Opportunities to Implementing Sexual History Screening and Human Immunodeficiency Virus Pre-Exposure Prophylaxis at a Federally Qualified Health Center.

Sexual history screening (SHS) is recommended to determine risk for acquisition of human immunodeficiency virus (HIV) and eligibility for pre-exposure prophylaxis (PrEP). SHS and PrEP are underutilized, sequential screening, and prevention practices. This study aimed to understand factors impacting the implementation of SHS and PrEP at a multi-site federally qualified health center (FQHC) in Connecticut. Guided by the Consolidated Framework for Implementation Research, semistructured interviews were conducted on Zoom with primary care providers (PCPs), medical assistants, clinical leadership, and PrEP navigators. Convenience and purposive sampling took place via email until thematic saturation was achieved. Thematic analysis was conducted. Twenty-two participants were interviewed for this study. PCPs lacked knowledge and reported limited or no use of SHS to determine patients' level of HIV risk, which may explain why most PCPs relied on patients to request PrEP. While PCPs perceived organizational support to prescribe PrEP, clinical staff were unaware of structural resources. Lastly, participants described a vertical trajectory of influence from external sources (policies and insurance) to time allocated to appointments that limits their ability to implement SHS and PrEP, further complicated by the electronic health record and disparities in structural resources across clinical sites. This study provides foundational evidence for future research on implementation strategies to improve HIV prevention through universal, comprehensive SHS to identify patients for PrEP. Overcoming barriers to SHS and PrEP, particularly in clinical settings such as FQHCs that care for vulnerable populations, may improve identification, prevention, and treatment of HIV and aid in ending the HIV epidemic.

Spatial distribution and determinants of HIV high burden in the Southern African sub-region.

Spatial analysis at different levels can help understand spatial variation of human immunodeficiency virus (HIV) infection, disease drivers, and targeted interventions. Combining spatial analysis and the evaluation of the determinants of the HIV burden in Southern African countries is essential for a better understanding of the disease dynamics in high-burden settings. The study countries were selected based on the availability of demographic and health surveys (DHS) and corresponding geographic coordinates. We used multivariable regression to evaluate the determinants of HIV burden and assessed the presence and nature of HIV spatial autocorrelation in six Southern African countries. The overall prevalence of HIV for each country varied between 11.3% in Zambia and 22.4% in South Africa. The HIV prevalence rate was higher among female respondents in all six countries. There were reductions in prevalence estimates in most countries yearly from 2011 to 2020. The hotspot cluster findings show that the major cities in each country are the key sites of high HIV burden. Compared with female respondents, the odds of being HIV positive were lesser among the male respondents. The probability of HIV infection was higher among those who had sexually transmitted infections (STI) in the last 12 months, divorced and widowed individuals, and women aged 25 years and older. Our research findings show that analysis of survey data could provide reasonable estimates of the wide-ranging spatial structure of the HIV epidemic in Southern African countries. Key determinants such as individuals who are divorced, middle-aged women, and people who recently treated STIs, should be the focus of HIV prevention and control interventions. The spatial distribution of high-burden areas for HIV in the selected countries was more pronounced in the major cities. Interventions should also be focused on locations identified as hotspot clusters.

Safe sex negotiation and HIV risk reduction among women: A cross-sectional analysis of Burkina Faso 2021 Demographic and Health Survey.

Women are biologically more susceptible to the Human Immunodeficiency Virus (HIV) and other sexually transmitted Infections (STIs) because receptive sex is riskier than insertive. Despite condom use being the staple preventive method for HIV infection (over 80% efficacy), in Sub-Saharan African countries like Burkina Faso, a high burden of HIV and the unmet need for condom use coexist. Moreover, even though women in SSA are disproportionately HIV positive, they are reportedly less capable of negotiating condom use for HIV risk reduction. Thus, using the Health Believe Model (HBM), this study explored the factors that influence condom use among women within the context of HIV prevention, with a key interest in condom use negotiation. Using the women's dataset of the 2021 Burkina Faso Demographic and Health Survey and applying logistic regression models, this study examined the factors associated with condom use for HIV risk reduction. Women who had confidence to negotiate condom use with their partners (OR = 1.57, P<0.001, 95%CI: 1.29, 1.91), those with secondary education (OR = 1.38, P<0.05, 95%CI: 1.07 1.77), from richest households (OR = 1.64, P<0.05, 95%CI: 1.08, 2.47), the employed (OR = 1.23, P<0.05, 95%CI: 1.02, 1.49), women with knowledge of sexually transmitted infections (OR = 1.58, P<0.001, 95%CI: 1.26, 1.97), those who have ever been tested for HIV (OR = 1.85, P<0.001, 95%CI: 1.52 2.24), as well as those who knew that a healthy-looking person can have HIV (OR = 2.64, P<0.001, 95%CI: 2.15, 3.24) were all significantly more likely to practice condom use for HIV risk reduction. Also, religion and geographical location of participants significantly predicted condom use for HIV risk reduction in the study context. The ability to negotiate condom use, knowledge of HIV and STIs, the socioeconomic status of women, as well as their geographical location, influence their practice of safer sex for HIV risk reduction in Burkina Faso.
