RESUMO

Objective To evaluate cervical cancer screening with primary human papillomavirus (HPV) testing in Mozambique, a country with one of the highest burdens of cervical cancer globally. Methods Women aged 30­49 years were prospectively enrolled and offered primary HPV testing using either self- collected or provider- collected specimens. Patients who tested positive for HPV underwent visual assessment for treatment using visual inspection with acetic acid to determine eligibility for thermal ablation. If ineligible, they were referred for excision with a loop electrosurgical excision procedure, for cold knife conization, or for cervical biopsy if malignancy was suspected. Results Between January 2020 and January 2023, 9014 patients underwent cervical cancer screening. Median age was 37 years (range 30­49) and 4122 women (45.7%) were patients living with HIV. Most (n=8792, 97.5%) chose self- collection. The HPV positivity rate was 31.1% overall and 39.5% among patients living with HIV. Of the 2805 HPV- positive patients, 2588 (92.3%) returned for all steps of their diagnostic work- up and treatment, including ablation (n=2383, 92.1%), loop electrosurgical excision procedure (n=169, 6.5%), and cold knife conization (n=5, 0.2%). Thirty- one patients (1.2%) were diagnosed with cancer and referred to gynecologic oncology. Conclusion It is feasible to perform cervical cancer screening with primary HPV testing and follow- up in low- resource settings. Participants preferred self- collection, and the majority of screen- positive patients completed all steps of their diagnostic work- up and treatment. Our findings provide important information for further implementation and scale- up of cervical cancer screening and treatment services as part of the WHO global strategy for the elimination of cervical cancer.

RESUMO

OBJECTIVE: This study examined the prevalence, severity and risk factors of anaemia among adult people living with HIV attending an antiretroviral therapy centre in Woreta Primary Hospital, Woreta town, Ethiopia. DESIGN: Hospital-based retrospective cross-sectional study. SETTING: Public health facility that provides HIV care in Woreta town. PARTICIPANTS: A total of 289 medical records of adults living with HIV/AIDS on highly active antiretroviral therapy from February 2019 to September 2023 at government hospital were reviewed using a systematic sampling method. The data were entered using Epi-info V.7 and exported to SPSS V.23 for data analysis. The data were analysed using bivariate and then multivariate logistic regression models in order to identify variables associated with anaemia. At the 95% CI level, variables having a p value of <0.05 were deemed to be statistically significant predictors. PRIMARY OUTCOME: Prevalence and severity of anaemia and its predictors among adult patients living with HIV on antiretroviral therapy in Woreta Primary Hospital. RESULTS: The total prevalence of anaemia was 31.5% (95% CI 28.9 to 33.8). The prevalence of mild, moderate and severe anaemia was 20.42%, 10.38% and 0.70%, respectively. Predictors independently linked with anaemia were female sex (adjusted OR (AOR) 1.08), age ≥40 years (AOR 1.21), lived with HIV >10 years (AOR 2.31), CD4 counts <200 cells/µL (AOR 3.81), non-suppressed viral load (AOR 1.28), history of opportunistic infections (AOR 1.54), WHO clinical stages III and IV (AOR 1.37 and 2.23, respectively) and history of parasitic infestation (AOR 2.81). CONCLUSIONS: A sizeable proportion of participants were found anaemic. Female sex, older age, longer periods lived with the virus, lower CD4 count, non-suppressed viral load, history of opportunistic infections, WHO clinical stages III and IV and history of parasitic infestation were the contributing factors. Therefore, to improve the anaemic status and living circumstances of patients living with HIV, immediate action on the linked factors is needed, such as monitoring for maintenance of CD4 counts >200 cells/µL and avoiding progression of HIV to the advanced WHO clinical stages, suppressed viral load, preventing opportunistic infections and parasitic infestation.

RESUMO

Tunneling nanotubes (TNTs) are cellular connections, which represent a novel route for cell-to-cell communication. Strong evidence points to a role for TNTs in the intercellular transfer of signals, molecules, organelles, and pathogens, involving them in many cellular functions. In myeloid cells (e.g., monocytes/macrophages, dendritic cells, and osteoclasts), intercellular communication via TNT contributes to their differentiation and immune functions, by favoring material and pathogen transfer, as well as cell fusion. This chapter addresses the complexity of the definition and characterization of TNTs in myeloid cells, the different processes involved in their formation, their existence in vivo, and finally their function(s) in health and infectious diseases, with the example of HIV-1 infection.

RESUMO

Introduction. Renal functional reserve (RFR) is the kidney capability of increasing its basal glomerular filtration rate (GFR) at least 20% after an adequate stimulus. Renal disorders have been reported in seropositive HIV patients, particularly the decrease in glomerular filtration rate (eGFR), nephrotic syndrome, and proximal tubular deficiency associated with the disease itself or the use of some anti-retroviral treatments. Thus, it was decided to carry out a prospective study in order to evaluate if RFR test was preserved in naive HIV patients. Material and Method. GFR was measured by using cimetidine-aided creatinine clearance (CACC), and RFR as described Hellerstein et al. in seropositive naive HIV patients and healthy volunteers. Results. RFR was evaluated in 12 naïve HIV patients who showed positive RFR (24.8±2%), but significantly lower compared to RFR in 9 control individuals (90.3 ± 5%). Conclusion. In this study was found that renal functional reserve was positive in naïve HIV patients, but significantly lower compared to renal functional reserve achieved by seronegative healthy individuals.

RESUMO

Introduction: tuberculosis remains a major public health problem, with continuing high levels of prevalence, and mortality. In Niger, the incidence of tuberculosis remains high. This study aims to investigate the epidemiology of pulmonary tuberculosis at the National Anti-Tuberculosis Center of Niamey in Niger. Methods: this study used a quantitative approach with a retrospective and descriptive design. Data were obtained from positive pulmonary tuberculosis cases detected by microscopy on Ziehl-Neelsen stained sputum at the National Anti-Tuberculosis Center (NATC) in Niamey, Niger covered the period between June 2017 and January 2020. 955 pulmonary TB patients were recorded whose diagnosis was based either on clinical-radiological arguments (thus negative microscopy) or positive microscopy. This form was used to collect data recorded in the clinical case registers, registers, and Excel files of the GeneXpert platform of the NATC laboratory. Results: eighty-nine-point eleven percent (89.11%) of the patients were microscopy-positive. Among the study population, men were the most affected by tuberculosis with 80.03%. The 25-34 age group, representing 23.77%, was the most affected. 6.93% of patients were co-infected with tuberculosis and HIV. All patients were put on treatment, with a therapeutic success rate of 72.38% and a therapeutic failure rate of 10.95%. Among the cases of therapeutic failure, 80.90% had Mycobacterium tuberculosis complex detected and 27.14% were resistant to Rifampicin. Conclusion: Niger continues to have a tuberculosis epidemic which requires monitoring. Improving the diagnostic system for more effective management of the disease is important for appropriate diagnosis and treatment.

RESUMO

Introduction: female sex workers (FSWs) are vulnerable to acquiring HIV and other sexually transmitted infections due to unprotected sex. Understanding and addressing the gaps in safer sex among FSWs can help to reduce HIV acquisition and transmission. This study described sexual practices, their correlates and use of HIV services among FSWs in Mombasa County, Kenya. Methods: participants were recruited for a baseline survey by a time-location cluster randomized design at predetermined intervals from five bars and five clubs in Mombasa County until a sample size of 160 was reached. Descriptive statistics and inferential analysis using R were conducted, and p<0.05 was regarded as statistically significant. Results: nearly all (99%) of the participants were unmarried, and 11% had tertiary education. Ninety-eight percent (98%) reported vaginal intercourse, 51% reported using alcohol/drugs before sex, and 28% practiced unprotected intercourse. About 64% had tested for HIV within three months, 14% believed that it is safe to reuse condoms, and 10% that it is safe to engage in unprotected sex. In bi-variate analysis, FSWs were more likely to engage in unprotected intercourse if they reported more frequent sex, more frequent sex with regular clients, poor HIV knowledge, alcohol/drug use, and violence. In multivariate analysis, risky sexual practices were associated with frequency of sexual intercourse, alcohol/drug use, and poor HIV knowledge. Conclusion: female sex workers engage in unprotected sex while under the influence of substances, belief in re-using condoms and have high frequency of sexual intercourse. Inadequate knowledge of HIV and substance use significantly correlated with unprotected sex. Interventions to address these modifiable factors are needed to mitigate the risk of HIV among FSWs.

RESUMO

BACKGROUND: HIV notification and testing integrated into partner service (PS) practices among HIV-positive individuals have been proven to be an efficient approach for case finding, although it remains a weak link in China. Although nonmarital sexual activities accounted for a large proportion of newly diagnosed HIV-positive cases in China, little is known about PS uptake and associated factors within nonmarital partnerships. OBJECTIVE: This study aimed to describe HIV PS utilization and its associated factors among HIV-positive individuals with nonmarital sexual partners. METHODS: We recruited newly diagnosed HIV-positive individuals who had nonmarital sexual partners in 2022 in Zhejiang Province and offered them PS. We described the PS uptake cascade within sexual partner categories and analyzed the associated factors with 3 primary outcomes from the participants' perspective: nonmarital partner enumeration, HIV testing, and HIV positivity. RESULTS: In this study, 3509 HIV-positive individuals were recruited as participants, and they enumerated 2507 nonmarital sex partners (2507/14,556, 17.2% of all nonmarital sex partners) with contact information. Among these, 43.1% (1090/2507) underwent an HIV test, with an HIV-positive rate of 28.3% (309/1090). Heterosexual commercial partners were the least likely of being enumerated (441/4292, 10.3%) and had the highest HIV-positive rate (40/107, 37.4%). At the participant level, 48.1% (1688/3509) of the participants enumerated at least one nonmarital sex partner with contact information, 52.7% (890/1688) had a sex partner tested for HIV, and 31% (276/890) had at least one nonmarital sex partner who tested positive. Multivariate analysis indicated that gender and transmission route were associated with both nonmarital sex partner enumeration and HIV testing. Age and occupation were associated with nonmarital sex partner enumeration and HIV positivity. Compared with participants who had no regular nonmarital sex partner, those who had a regular nonmarital sex partner were more likely to enumerate nonmarital sex partners (adjusted odds ratio [aOR] 3.017, 95% CI 2.560-3.554), have them get tested for HIV (aOR 1.725, 95% CI 1.403-2.122), and have an HIV-positive nonmarital sex partner (aOR 1.962, 95% CI 1.454-2.647). CONCLUSIONS: The percentage of partner enumeration was low, and HIV testing rate was moderate among nonmarital partnerships of HIV-positive individuals. More efforts should be made to improve PS practices among HIV-positive individuals and address the gap in partner enumeration, especially for heterosexual commercial nonmarital partnerships. Additionally, enhancing PS operational skills among health care personnel could increase the overall efficiency of PS uptake in China.

RESUMO

BACKGROUND: Male factory workers in China are vulnerable to HIV transmission. Commercial and nonmarital noncommercial contacts are the driving forces of heterosexual HIV transmission among male factory workers in China. There is a lack of effective HIV interventions for male factory workers in China. OBJECTIVE: The primary objective of this randomized controlled trial was to compare the efficacy of an enhanced versus the standard version of a WeChat mini program in reducing sexual intercourse with nonregular female sex partners and female sex workers among male factory workers in Shenzhen, China. METHODS: A nonblinded 2-arm parallel randomized controlled trial was conducted between December 2021 and April 2023. Participants were adult male factory workers in Shenzhen who had access to a smartphone and WeChat. Those who had oral or anal sex with a man or self-reported as HIV positive were excluded. A total of 247 participants were randomly assigned to the intervention group (n=125, 50.6%) or the control group (n=122, 49.4%); 221 (89.5%) and 220 (89.1%) completed follow-up surveys at T1 (6 months after completion of the interventions) and T2 (6 months after T1). Participants in the control group had access to the standard WeChat mini program that provided basic HIV-related knowledge and information about local free HIV testing services. Participants in the intervention group had access to the enhanced WeChat mini program. The enhanced mini program covered all the information in the standard mini program. In addition, the enhanced mini program assessed users' behaviors and invited users to watch different web-based videos on reducing nonmarital sexual contacts and promoting HIV testing based on their behavioral characteristics at months 0 and 1. The videos were developed based on in-depth interviews with male factory workers. Intention-to-treat analysis was used for outcome analyses. Multiple imputation was used to replace missing outcome values at T1 and T2. RESULTS: At T1, fewer participants in the intervention group reported sexual intercourse with a nonregular female sex partner in the past 6 months compared with the control group (1/125, 0.8% vs 8/122, 6.6%; relative risk=0.12, 95% CI 0.02-0.96; P=.02). However, there were no between-group differences in sexual intercourse with a nonregular female sex partner at T2 (10/125, 8% vs 14/122, 11.5%; P=.36) or sexual intercourse with a female sex worker at T1 (2/125, 1.6% vs 2/122, 1.6%; P=.98) or T2 (8/125, 6.4% vs 8/122, 6.6%; P=.96). CONCLUSIONS: The enhanced WeChat mini program was more effective than the standard WeChat mini program in reducing sexual intercourse with nonregular female sex partners among male factory workers in the short term but not in the longer term. Improvements should be made to the WeChat mini program before implementation. TRIAL REGISTRATION: ClinicalTrials.gov NCT05811611; https://clinicaltrials.gov/study/NCT05811611.

RESUMO

Background Structural stigma and institutionalised discrimination towards people living with HIV remain pervasive in many settings. However, qualitative explorations of experiences of stigma, health and social service engagement, and quality of life among people living with HIV in Singapore remain under-researched. Methods Semi-structured interviews were conducted with 73 participants in Singapore. These included 56 people living with HIV (30 men who have sex with men, 23 heterosexual men, and 3 women) and 17 stakeholders including healthcare professionals and other allied workers. Interviews focused on participant perspectives or experiences of HIV diagnosis, navigating healthcare, attitudes towards HIV, and impact of HIV on relationships. Data were analysed through inductive thematic analysis. Results Our findings were framed within a minority stress model, highlighting the distal and proximal stressors relating to living with HIV. With regard to distal stressors, participants highlighted that they had experienced or were aware of institutionalised discrimination towards people living with HIV across various aspects of their lives. These included experiences - overt and covert - of discrimination in education, workplace, and healthcare settings. With regard to proximal stressors, participants highlighted the role of anticipated stigma and the stress of concealment. This included participants' fear of potential legal and/or social repercussions resulting from the disclosure of their HIV status, actions that they may not be able to anticipate and articulate. Although employers may not overtly discriminate, the fear of such anticipated discrimination influenced decisions to conceal HIV status in job applications and workplaces. This restricted agency for the people living with HIV in our study by affecting their regular medical follow-ups, socialising behaviours, and overall quality of life. Consequently, many participants felt that concealment of their status, and forgoing potential educational, employment, and even health opportunities, were the only ways of protecting themselves from such forms of stigma and discrimination. Conclusions This study found that anticipated stigma and discrimination diminished the quality of life of people living with HIV in Singapore. Implementing an anti-discrimination framework could address the unpredictability and alleviate the manifold unknowns of anticipated stigma.

RESUMO

BACKGROUND: To inform global ambitions to end AIDS, evaluation of progress toward HIV incidence reduction requires robust methods to measure incidence. Although HIV diagnosis date in routine HIV/AIDS surveillance systems are often used as a surrogate marker for incidence, it can be misleading if acquisition of transmission occurred years before testing. Other information present in data such as antibody testing dates, avidity testing result, and CD4 counts can assist, but the degree of missing data is often prohibitive. METHODS: We constructed a Bayesian statistical model to estimate the annual proportion of first ever HIV diagnoses in Scotland (period 2015-2019) that represent recent HIV infection (ie, occurring within the previous 3-4 months) and incident HIV infection (ie, infection within the previous 12 months), by synthesizing avidity testing results and surveillance data on the interval since last negative HIV test. RESULTS: Over the 5-year analysis period, the model-estimated proportion of incident infection was 43.9% (95% CI: 40.9 to 47.0), and the proportion of recent HIV infection was 21.6% (95% CI: 19.1 to 24.1). Among the mode of HIV acquisition categories, the highest proportion of recent infection was estimated for people who inject drugs: 27.4% (95% CI: 20.4 to 34.4). CONCLUSIONS: The Bayesian approach is appropriate for the high prevalence of missing data that can occur in routine surveillance data sets. The proposed model will aid countries in improving their understanding of the number of people who have recently acquired their infection, which is needed to progress toward the goal of HIV transmission elimination.

RESUMO

BACKGROUND: The pathogenesis of HIV-associated neurocognitive (NC) impairment is multifactorial, and antiretroviral (ARV) neurotoxicity may contribute. However, interventional pharmacological studies are limited. METHODS: Single-blind, randomized (1:1), controlled trial to assess the change of NC performance (Global Deficit Score, GDS, and domain scores) in PLWH with NC impairment randomized to continue their standard of care treatment or to switch to a less neurotoxic ARV regimen: darunavir/cobicistat, maraviroc, emtricitabine (MARAND-X). Participants had plasma and cerebrospinal fluid HIV RNA< 50 copies/mL, R5-tropic HIV, and were on ARV regimens that did not include efavirenz and darunavir. The change of resting-state electroencephalography was also evaluated. The outcomes were assessed at week 24 of the intervention through tests for longitudinal paired data and mixed-effect models. RESULTS: Thirty-eight participants were enrolled and 28 completed the follow-up. Global Deficit Score improved over time but with no difference between arms in longitudinal adjusted models. Perceptual functions improved in the MARAND-X, while long-term memory improved only in participants within the MARAND-X for whom the central nervous system penetration-effectiveness (CNS penetration effectiveness) score increased by ≥3. No significant changes in resting-state electroencephalography were observed. CONCLUSIONS: In this small but well-controlled study, the use of less neurotoxic ARV showed no major beneficial effect over an unchanged regimen. The beneficial effects on the memory domain of increasing CNS penetration effectiveness score suggest that ARV neuropenetration may have a role in cognitive function.

RESUMO

BACKGROUND: Frailty is associated with obesity-related comorbidities, but the relationship with nonalcoholic fatty liver disease (NAFLD) in people with HIV has been incompletely described. Our objective was to assess the associations between NAFLD and frailty. METHODS: Cross-sectional and longitudinal analysis of men in the Multicenter AIDS Cohort Study. NAFLD was defined as a liver/spleen ratio <1.0 on abdominal computed tomography scans; frailty was defined by the frailty phenotype as having 3 of the following: weakness, slowness, weight loss, exhaustion, and low physical activity. RESULTS: Men without (n = 200) and with HIV (n = 292) were included. NAFLD prevalence was 21% vs 16% and frailty 12% vs 17%, respectively. Among men with NAFLD, frailty was more prevalent in men without HIV (21% vs 11%). In multivariate analysis, NAFLD was significantly associated with frailty after controlling for significant variables. Men without HIV and NAFLD had 2.6 times higher probability [95% confidence interval (CI): 1.2- to 5.7] of frailty relative to men with neither HIV nor NAFLD. This association was not seen in men with HIV. The probability of frailty was higher among men without HIV with NAFLD (27% vs 10% in men without NAFLD) but lower among men with HIV with NAFLD (14% vs 19% in men without NAFLD). No significant relationships were found in longitudinal analyses. CONCLUSIONS: NAFLD was independently associated with frailty among men without HIV but not men with HIV, despite increased prevalence of frailty among men with HIV. The mechanisms of the muscle-liver-adipose tissue axis underlying NAFLD might differ by HIV serostatus.

RESUMO

BACKGROUND: People living with HIV (PLWH) often report fatigue even when viral load is suppressed. Obstructive sleep apnea (OSA), which is often associated with fatigue, is common in PLWH, but whether OSA explains fatigue in this population is unknown. SETTING: Academic university-affiliated HIV and Sleep Medicine Clinics. METHODS: PLWH, aged 18-65 years, with a body mass index of 20-35 kg/m2 and viral suppression (RNA <200 copies per mL), were recruited to undergo daytime questionnaires, including the Functional Assessment of Chronic Illness Therapy Fatigue Scale and Epworth Sleepiness Scale, 7 days of actigraphy (to determine daily sleep duration and activity amplitude and rhythms), and an in-laboratory polysomnography to assess for the presence and severity of OSA. RESULTS: Of 120 subjects with evaluable data, 90 (75%) had OSA using the American Academy of Sleep Medicine 3% desaturation or arousal criteria, with an apnea-hypopnea index >5/h. There was no difference in Functional Assessment of Chronic Illness Therapy scores between those with and without OSA, although those with OSA did report more daytime sleepiness as measured using the Epworth Sleepiness Scale. In a multivariable model, predictors of fatigue included more variable daily sleep durations and decreased mean activity counts. Sleepiness was predicted by the presence of OSA. CONCLUSION: OSA was very common in our cohort of PLWH, with those with OSA reporting more sleepiness but not more fatigue. Variability in sleep duration was associated with increased fatigue. Further study is needed to determine if treatment of OSA, or an emphasis on sleep consistency and timing, improves symptoms of fatigue in PLWH.

RESUMO

BACKGROUND: Cocaine-one of the most frequently abused illicit drugs among persons living with HIV [people living with HIV (PLWH)]-slows the decline of viral production after antiretroviral therapy and is associated with higher HIV viral load, more rapid HIV progression, and increased mortality. SETTING: We examined the impact of cocaine use on the CD4+ T-cell HIV latent reservoir (HLR) in virally suppressed PLWH participating in a national, longitudinal cohort study of the natural and treated history of HIV in the United States. METHODS: CD4+ T-cell genomic DNA from 434 women of diverse ancestry (ie, 75% Black, 14% Hispanic, 12% White) who self-reported cocaine use (ie, 160 cocaine users, 59 prior users, 215 non-users) was analyzed using the Intact Proviral HIV DNA Assay, measuring intact provirus per 106 CD4+ T cells. FINDINGS: HIV latent reservoir size differed by cocaine use (ie, median [interquartile range]: 72 [14-193] for never users, 165 [63-387] for prior users, 184 [28-502] for current users), which was statistically significantly larger in both prior (P = 0.023) and current (P = 0.001) cocaine users compared with never users. CONCLUSIONS: Cocaine use may contribute to a larger replication competent HLR in CD4+ T cells among virologically suppressed women living with HIV. Our findings are important because women are underrepresented in HIV reservoir studies and in studies of the impact of cocaine use on outcomes among PLWH.

RESUMO

The study of human immunodeficiency virus (HIV)-related stigma and discrimination has been burgeoning with important implications for public health and society, as it negatively impacts people living with HIV. However, data on the experiences of rural women living with HIV/Acquired Immune Deficiency Syndrome (AIDS) in Zimbabwe are lacking. Women represent 50% of the global pandemic, while deaths from AIDS-related illnesses have exceeded 35 million. This study aimed to explore the experiences of rural women living with HIV/AIDS in Zimbabwe. Forty rural women living with HIV were selected from 6 villages (one village per district) of Matabeleland South Province in Zimbabwe. A qualitative descriptive research design using in-depth individual interviews from 22 purposefully selected rural women living with HIV and 3 focus groups, was used to collect the study data. The transcripts of the interviews were analyzed using interpretative phenomenological analysis. Three interconnected themes were identified: social prejudice, social discrimination, and psychosocial dysfunction. A key finding in the themes was that women living with HIV in rural Zimbabwe were psychosocially dysfunctional because of social prejudice and discrimination perpetrated against them by significant others in their communities. The findings provide a valuable understanding of women's experiences of living with HIV and AIDS in Africa's low-income countries. These results can be used by researchers, clinicians, mental health providers, and policymakers to address the unique needs of rural women living with HIV/AIDS.

RESUMO

BACKGROUND: Abortion is a public health problem in Latin America and is more common among women living with HIV. OBJECTIVE: to verify the incidence and factors associated with induced abortion in a cohort of women living with HIV assisted in a reference service for care for individuals with HIV/AIDS in Rio de Janeiro/Brazil. METHODS: Prospective cohort during the period 1996-2016. We estimated the incidence of induced abortions during follow-up in the cohort by calculating person-time incidence rates [per 100 persons-years (PY)] and investigated the factors associated with the outcome "induced abortion" using a generalized linear mixed model. RESULTS: 753 women and 210 pregnancies were included in the present analysis. We estimated an induced abortion incidence rate of 0.68/100 persons-years (95% confidence interval [CI]: 0.47; 0.94) in the study period, with a significant reduction after 2006. The main factors associated with an induced abortion were currently living with a partner (adjusted OR [AdjOR] 0.32 95% CI: 0.10-0.98), number of children (2 children AdjOR 0.12, 95% CI: 0.02-0.95) and the type of antiretroviral treatment used (regimen without Efavirenz: AdjOR: 0.11, 95% CI 0.02-0.70). CONCLUSIONS: We showed a significant reduction in the incidence of induced abortions in a cohort of women living with HIV in Rio de Janeiro, Brazil, probably due to a decrease in the incidence of pregnancies observed in the same period. The factors associated with a lower occurrence of induced abortion suggest a good integration between the clinical and reproductive assistance offered to those women.

RESUMO

Background: Drug users are a high-risk group for HIV infection and are prominent HIV carriers. Given the emergence of new drugs, we explored current drug-using behaviors, HIV infections, and the correlation between drug-using behaviors and HIV infection risk among drug users from 2014 to 2021. Objective: We aimed to identify the prevalence of HIV infection risk among drug users and explore drug use behaviors based on the updated data, which could provide evidence for the precision of HIV prevention strategies among drug users. Methods: Data were collected from sentinel surveillance of drug users in rehabilitation centers and communities in Hangzhou (2014-2021), including sociodemographic characteristics, HIV awareness, drug use, risky sexual behaviors, and HIV infection status. Multivariate logistic regression was used to identify the factors influencing HIV infection and risky sexual behaviors among drug users. Results: In total, 5623 drug users (male: n=4734, 84.19%; age: mean 38.38, SD 9.94 years) were included. New drugs dominated among the participants (n=3674, 65.34%). The main mode of drug use was noninjection (n=4756, 84.58%). Overall, for 27.45% (n=1544) of injected drugs in the last month before the investigation, the average daily injection frequency was 3.10 (SD 8.24). Meanwhile, 3.43% of participants shared needles. The incidence of sexual behaviors after drug use was 33.13% (n=1863), with 35.75% (n=666) of them using a condom in the last time. Overall, 116 participants tested positive for HIV antibodies (infection rate=2.06%). New drug users exhibited more postuse sexual behaviors than traditional drug users (odds ratio [OR] 7.771, 95% CI 6.126-9.856; P<.001). HIV-aware drug users were more likely to engage in risky sexual behaviors (OR 1.624, 95% CI 1.152-2.291; P=.006). New-type drug users were more likely to engage in unprotected sexual behavior (OR 1.457, 95% CI 1.055-2.011; P=.02). Paradoxically, drug users with greater HIV awareness were more prone to engaging in unprotected sexual behavior (OR 5.820, 95% CI 4.650-7.284; P<.001). Women engaged less in unprotected sex than men (OR 0.356, 95% CI 0.190-0.665; P=.001). HIV rates were higher among injecting drug users (OR 2.692, 95% CI 0.995-7.287; P=.04) and lower among drug users who used condoms during recent sex than those who did not (OR 0.202, 95% CI 0.076-0.537; P=.001). Higher education levels were associated with higher HIV infection rates. However, there was no significant correlation between HIV cognition level and HIV infection. Conclusions: New drug types and noninjection were the main patterns in last 7 years. Using new types of drugs, rather than traditional drugs, was associated with an increased risk of HIV infection. Injection drug use was a risk factor for HIV infection. HIV awareness among drug users was high, but the incidence of risky sexual behaviors remained high. Therefore, it is important to promote the behavioral transformation of high-risk populations from cognition to attitude, and then to taking protective measures.

RESUMO

Objective: This meta-analysis aims to evaluate the global prevalence of mental disorders among young people living with HIV. Methods: A comprehensive search was conducted of the PubMed, Embase, and Cochrane Library databases for articles relevant to the study, published between January 2013 and June 2023. To identify sources of heterogeneity and compare prevalence estimates among various groups, subgroup analyses were conducted. Study heterogeneity was assessed using Cochran's Q and the I 2 tests. The robustness of the findings was ascertained through sensitivity analyses, while publication bias was evaluated with funnel plots and Egger's test. Results: Sixty studies were included in this meta-analysis. It revealed that approximately one-quarter of YLWH experience depression, with a prevalence of 24.6% (95% CI: 21.1-28.2%). The prevalence of anxiety was found to be 17.0% (95% CI: 11.4-22.6%). Regarding suicidality, the prevalence of suicidal ideation and lifetime suicidal ideation in YLWH was 16.8% (95% CI: 11.3-22.4%) and 29.7% (95% CI: 23.7-35.7%), respectively. Additionally, the prevalence rates for suicidal attempts and lifetime suicidal attempts were 9.7% (95% CI: 4.0-15.4%) and 12.9% (95% CI: 2.8-23.1%), respectively. The prevalence of Post-Traumatic Stress Disorder and Attention Deficit Hyperactivity Disorder was identified as 10.5% (95% CI: 5.8-15.2%) and 5.0% (95% CI: 3.1-7.0%), respectively. Conclusion: The findings indicate a heightened risk of mental disorders among YLWH, underscoring the necessity for targeted intervention strategies to mitigate their suffering and potentially diminish the adverse impacts.
