RESUMO

Background: Cervical cancer is the fourth most common cancer among females globally, with a high incidence and high mortality among females in developing countries. This retrospective case-control study aimed to investigate the association between oral contraceptives and cervical cancer, on which insufficient evidence still exists. Material and Methods: To examine the association between oral contraceptives and cervical cancer based on 7,496 females aged over 20 years from the National Health and Nutrition Examination Survey, multivariable logistic regression conducted from 1999 to 2016 was used. Results: Contraceptive use was positively associated with cervical cancer risk. In model 1 (unadjusted), a 195% increased risk of cervical cancer was observed among those who used oral contraceptives (odds ratio [OR] = 2.27, 95% confidence interval [CI] = 1.39-3.98, p = 0.002) compared to those who did not. In addition, the ORs for the exposed population were 1.74 (95% CI = 1.05-3.08, p = 0.041) and 1.93 (95% CI = 1.16-3.44, p = 0.017) in model 2 (adjusted for age, race, and body mass index [BMI]) and model 3 (adjusted for education level, ratio of family income to poverty, drinking status, smoking status, number of pregnancies, age at first sex, number of sexual partners, and whether to receive the human papillomavirus (HPV) vaccine in addition to model 2), respectively. Furthermore, subgroup analyses stratified by age, smoking status, BMI, age at first sex, number of sexual partners, and whether to receive the HPV vaccine also revealed that oral contraceptives were significantly associated with cervical cancer. Conclusion: This study demonstrated that oral contraceptive use increased the risk of cervical cancer. In addition, the higher risk, including individuals older than 45 years, having a high BMI (≥30 kg/m2), being current smokers, and having more than five sexual partners, may contribute to the development of cervical cancer.

RESUMO

INTRODUCTION: Assisted partner services (APS), or exposure notification and HIV testing for sexual partners of persons diagnosed HIV positive (index clients), is recommended by the World Health Organization. Most APS literature focuses on outcomes among index clients and their partners. There is little data on the benefits of providing APS to partners of partners diagnosed with HIV. METHODS: We utilized data from a large-scale APS implementation project across 31 facilities in western Kenya from 2018 to 2022. Females testing HIV positive at facilities were offered APS; those who consented provided contact information for all male sexual partners in the last 3 years. Male partners were notified of their potential HIV exposure and offered HIV testing services (HTS). Males newly testing positive were also offered APS and asked to provide contact information for their female partners in the last 3 years. Female partners of male partners (FPPs) were provided exposure notification and HTS. All participants with HIV were followed up at 12 months post-enrolment to assess linkage-to antiretroviral treatment (ART) and viral suppression. We compared HIV positivity, demographics and linkage outcomes among female index clients and FPPs. RESULTS: Overall, 5708 FPPs were elicited from male partners, of whom 4951 received HTS through APS (87% coverage); 291 FPPs newly tested HIV positive (6% yield), an additional 1743 (35.2%) reported a prior HIV diagnosis, of whom 99% were on ART at baseline. At 12 months follow-up, most FPPs were taking ART (92%) with very few adverse events: <1% reported intimate partner violence or reported relationship dissolution. FPPs were more likely than female index clients to report HIV risk behaviours including no condom use at last sex (45% vs. 30%) and multiple partners (38% vs. 19%). CONCLUSIONS: Providing HIV testing via APS to FPP is a safe and effective strategy to identify newly diagnosed females and achieve high linkage and retention to ART and can be an efficient means of identifying HIV cases in the era of declining HIV incidence. The high proportion of FPPs reporting HIV risk behaviours suggests APS may help interrupt community HIV transmission via increased knowledge of HIV status and linkage to treatment.

RESUMO

Introduction: Little is known about differences in HIV risk for trans women by partner gender, particularly with respect to social determinants and partner-level circumstances that affect behavior. We examined differences in demographic, social determinants, and HIV-related risk behaviors for trans women with cis men and trans women sexual partners. Materials and Methods: Data are from a cross-sectional survey of trans women and their sexual partners conducted between April 2020 and January 2021. Interviews were held remotely during shelter-in-place due to Covid-19 via videoconference. Analysis characterizedassociations between HIV risk and protective behaviors comparing trans women with cisgender men partners to trans women with non-cisgender sexual partners. Results: A total of 336 sexual partners were identified from 156 trans women. Trans women with cis men partners had significantly less education and employment and more incarceration and recidivism than trans women with trans women partners. Trans women and their cisgender men partners had shared experiences of unstable housing, incarceration, and HIV. Trans women with cisgender men partners reported significantly more sex exchange partners, receptive condomless sex, receptive or insertive condomless sex while using substances, and HIV infection compared to trans women with trans women partners. Conclusions: Trans women with cisgender men sexual partners faced higher HIV risk than trans women with trans women sexual partners. These risks may be related to the social and economic drivers that both trans women and their cis men partners faced, including barriers to education and employment, along with incarceration and recidivism. Interventions focused on economic stability, workforce development and post incarceration re-entry support for housing and employment for trans women with cis men partners and the cisgender men partners as well may have the most impact on reducing HIV risk and incidence.

RESUMO

OBJECTIVES: The 2022 mpox epidemic reached a peak in Belgium and the rest of Europe in July 2022, after which it unexpectedly subsided. This study investigates epidemiological, behavioral, and immunological factors behind the waning of the epidemic in Belgium. METHODS: We investigated temporal evolutions in the characteristics and behavior of mpox patients using national surveillance data and data from a prospective registry of mpox patients in the Institute of Tropical Medicine (Antwerp). We studied behavioral changes in the population at risk using a survey among HIV-preexposure prophylaxis (PrEP) users. We determined the seroprevalence of anti-orthopoxvirus antibodies among HIV-PrEP users across four-time points in 2022. RESULTS: Mpox patients diagnosed at the end of the epidemic had less sexual risk behavior compared to those diagnosed earlier: they engaged less in sex at mass events, had fewer sexual partners, and were less likely to belong to the sexual network's central group. Among HIV-PrEP users there were no notable changes in sexual behavior. Anti-orthopoxvirus seroprevalence did not notably increase before the start of national vaccination campaigns. CONCLUSION: The observed changes in group immunity and behavior in the population at greater risk of exposure to mpox seem unable to explain the waning of the mpox epidemic. A change in the profile of mpox patients might have contributed to the decline in cases.

RESUMO

OBJECTIVES: Approximately half of Japanese men aged 20-49 years have purchased sexual services, but data concerning the use of commercial sex work (CSW) in Japan remain scarce. METHODS: We used online survey data from the National Inventory of Japanese Sexual Behavior conducted in 2022 (N=4000 Japanese men aged 20-49 years). We calculated the median number of paid sexual partners over the lifetime. We performed logistic regression analysis to determine the sociodemographic, anthropometric and attitudinal factors associated with any lifetime CSW use among men in Japan. RESULTS: The median number of paid sexual partners reported among men who had ever used CSW was 6 (IQR 3-17) across the lifetime; the corresponding value for those who had ever used CSW in the past year was 2 (IQR 1-4) over the last 12 months. In general, those reporting lifetime use of CSW were significantly more likely than their CSW-naïve counterparts to be older, be married, be heterosexual or bisexual, have higher income and have higher education. Those reporting higher self-rated attractiveness, high or low satisfaction with their sex lives, a desire to increase their frequency of sex and considering sex to be an important aspect of their lives were also found to have a higher likelihood of having used CSW. CONCLUSIONS: High rates of CSW use in Japan likely reflect ease of access, low stigma with respect to use of sexual services and the diversity in the type of services offered. High-income, employed older men have more financial resources at their disposal to purchase services, which can be cost-prohibitive for part-time or unemployed young men with low incomes. These findings will serve as a launchpad for public health efforts directed at promoting safe sexual practices and improved sexually transmitted infection screening rates among users of CSW in Japan.

RESUMO

BACKGROUND: Risky sexual behavior (RSB) is one of the major youth sexual and reproductive health problems globally, including in Ethiopia. RSB among youth increases the risk of HIV infection, other sexually transmitted infections (STIs), unintended pregnancy, and unsafe abortion. Therefore, the aim of this study was to examine RSB and its associated factors among university students in Ethiopia. METHODS: A cross-sectional study was employed in six randomly selected public universities in Ethiopia from August 2021 to February 2022. A stratified two-stage sampling technique was applied to reach the required number of study participants, and a structured self-administered questionnaire was used. RSB was defined as having had sexual relationships with more than one partner and using condoms with a new sexual partner irregularly or not at all in the last 12 months. Bivariable and multivariable logistic regression analyses were used to identify factors associated with RSB among those participants who were sexually active. RESULTS: The prevalence of RSB among those who had had sexual intercourse in the last 12 months (n = 523) was 19.5% (n = 102). One hundred forty-four (29.9%) students had multiple sexual partners, and 325 (69.3%) students did not always use condoms with a new sexual partner. Adjusted odds ratios (AOR) showed that those students aged 21-24 years had lower odds of RSB than those aged above 25 years AOR 0.18 (95% CI 0.03-0.98). The adjusted odds of RSB were 6.7 times higher (95% CI 1.26-35.30) among students who started sex at the age of 10-17 years than those who started sex at 21 years and above and 3.9 times higher (95% CI 1.33-11.39) among students who had experienced emotional violence. CONCLUSION: RSB continues to be a problem among university students in Ethiopia. Those students who started sex at an early age and those who experienced emotional violence were more likely to engage in RSB. Therefore, universities in Ethiopia should implement strategies such as RSB targeted health education programs that consider early sexual debut, experiences of emotional violence, and safe sexual practices.

RESUMO

BACKGROUND: Lesotho's government has shown consistent efforts to implement social protection programmes. However, while recent evidence established a positive causal relationship between some of these programmes and food security there is little evidence on the extent to which these initiatives are associated with better educational and sexual and reproductive health outcomes among vulnerable adolescents in Lesotho. METHODS AND FINDINGS: The study uses cross-sectional, nationally representative data from the 2018 Lesotho Violence Against Children and Youth Survey. Our research examined the association between social protection receipt and educational and sexual and reproductive health outcomes among adolescents and young people (13-24 years) living in poverty. We employed multivariate logistic regression controlling for age, orphanhood, HIV status and sex. Social protection receipt was defined as household receipt of financial support from a governmental, non-governmental, or community-based program that provides income. Additionally, we fitted a marginal effects model by sex. Among the 3,506 adolescent females and males living in the two lowest poverty quintiles, receipt of social protection was associated with improvements in multiple adolescent outcomes: higher odds of consistent condom use (aOR 1.64, 95% CI 1.17-2.29), educational attainment (aOR 1.79, 95% CI 1.36-2.36), and school enrolment (aOR 2.19, 95% CI 1.44-3.34). Stratified analyses by sex showed that social protection receipt was also associated with reduced likelihood of child marriage among females (aOR 0.59, 95% CI 0.42-0.83) and higher odds of educational attainment and school enrolment among males (aOR 2.53, 95% CI 1.59-4.03 and aOR 3.11, 95% CI 1.56-6.19, respectively). CONCLUSIONS: Our study provides evidence that social protection programs are associated with improved educational, sexual and reproductive health and child marriage prevention outcomes among adolescents living in poverty. Implementing and expanding such social protection initiatives could prove instrumental in improving the well-being of vulnerable adolescents. CONTRIBUTIONS: Social protection programs have been increasing in sub-Saharan African countries, playing a pivotal role in poverty reduction, with Lesotho being no exception. Despite the optimistic outlook brought about by the implementation of the National Social Protection Strategy Lesotho I (2014-19) and II (2021-2031), the impact of these programs on some specific outcomes that concern the lives of the most vulnerable adolescents in Lesotho remains to some extent unexplored. Additionally, Lesotho grapples with high rates of HIV, adolescent pregnancy, child marriage and early school dropout, which can further contribute to poor long-term health and social outcomes among adolescents. In this study, we used data from the 2018 Lesotho Violence Against Children and Youth Survey (VACS) to examine the association between receiving social protection and multiple adolescent outcomes: educational, sexual and reproductive. The findings revealed that social protection programs, particularly the existing government-provided cash transfers, are significantly associated with multiple better outcomes among adolescents living in the poorest households in Lesotho. Such cash transfer schemes in Lesotho are associated with improved sexual and reproductive health outcomes for adolescent females, including reduced child marriage rates, and improved educational outcomes for males. These findings indicate that government-led social protection programmes are positively associated with favourable outcomes that can improve the quality of life for adolescents in resource-limited settings.

RESUMO

BACKGROUND: HIV partner notification services can help people living with HIV (PLHIV) to identify, locate, and inform their sexual and injecting partners who are exposed to HIV and refer them for proper and timely counseling and testing. To what extent these services were used by PLHIV and what are the related barriers and facilitators in southeast Iran are not known. So, this study aimed to explore HIV notification and its barriers and facilitators among PLHIV in Iran. METHODS: In this qualitative study, the number of 23 participants were recruited from November 2022 to February 2023 including PLHIV (N = 12), sexual partners of PLHIV (N = 5), and staff members (N = 6) of a Voluntary Counseling and Testing (VCT) center in Kerman located in the southeast of Iran. Our data collection included purposive sampling to increase variation. The content analysis was conducted using the Graneheim and Lundman approach. The analysis yielded 221 (out of 322) related codes related to HIV notification, its barriers, and its facilitators. These codes were further categorized into one main category with three categories and nine sub-categories. RESULTS: The main category was HIV notification approaches, HIV notification barriers, and facilitators. HIV notification approaches were notification through clear, and direct conversation, notification through gradual preparation and reassurance, notification due to being with PLHIV, notification through suspicious talking of the physician, and notification due to the behavior of others. Also, the barriers were classified into individual, social, and environmental, and healthcare system barriers and the facilitators were at PLHIV, healthcare staff, and community levels. Stigma was a barrier mentioned by most participants. Also, the main facilitator of HIV notification was social support, especially from the family side. CONCLUSIONS: The findings highlighted the multidimensionality of HIV notification emphasizing the importance of tailored support and education to enhance the notification process for PLHIV and their networks. Also, our results show that despite all the efforts to reduce stigma and discrimination in recent years, stigma still exists as a main obstacle to disclosing HIV status and other barriers are the product of stigma. It seems that all programs should be directed towards destigmatization.

RESUMO

BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention option for those who are most vulnerable to HIV infection, especially young women (YW). Objection by or lack of support from male sexual partners has been shown to impact YW's ability to take PrEP consistently. We explored the views of YW, and male partners and male peers of YW in Siaya County, Western Kenya, to illustrate how men influence, and can support, YW in using PrEP. METHODS: We used Photovoice to capture the views of YW ages 18-24 who were currently or previously enrolled in the DREAMS program and with current or previous experience taking PrEP. We also captured the views of YW's sexual partners and male peers. The YW completed eight photo assignments that focused on identifying factors influencing their PrEP use, and male participants completed four photo assignments focused on identifying ways men support or hinder YW's PrEP use. Photographs were presented and discussed in same- and mixed-gender groups using the SHOWeD method. YW also participated in in-depth interviews. The analysis focused on identifying themes that described men's influence on YW's PrEP adherence and persistence. RESULTS: Among YW, a restricting male influence on PrEP use emerged in the majority of photo assignments such that YW's photographs and discussions revealed that men were more often viewed as barriers than supporters. YW perceived that they had little autonomy over their sexual lives and choice to use PrEP. YW's PrEP use was perceived to be hindered by stigmatizing community narratives that influenced men's support of PrEP use among women. Male participants suggested that men would support YW's PrEP use if PrEP was better promoted in the community and if men were more knowledgeable about its benefits. CONCLUSIONS: A lack of support from male partners and peers and stigmatizing community narratives influence YW's PrEP use. Community-based programs should include education about PrEP specifically for male partners and peers of YW to positively influence PrEP use among YW.

RESUMO

OBJECTIVES: International travel combined with sex may contribute to dissemination of antimicrobial-resistant (AMR) Neisseria gonorrhoeae (Ng). To assess the role of travel in Ng strain susceptibility, we compared minimum inhibitory concentrations (MICs) for five antibiotics (ie, azithromycin, ceftriaxone, cefotaxime, cefixime and ciprofloxacin) in strains from clients with an exclusively Dutch sexual network and clients with an additional international sexual network. METHODS: From 2013 to 2019, we recorded recent residence of sexual partners of clients (and of their partners) with Ng at the Center for Sexual Health of Amsterdam. We categorised clients as having: (1) exclusively sexual partners residing in the Netherlands ('Dutch only') or (2) at least one partner residing outside the Netherlands. We categorised the country of residence of sexual partners by World Bank/EuroVoc regions. We analysed the difference of log-transformed MIC of Ng strains between categories using linear or hurdle regression for each antibiotic. RESULTS: We included 3367 gay and bisexual men who had sex with men (GBMSM), 516 women and 525 men who exclusively had sex with women (MSW) with Ng. Compared with GBMSM with a 'Dutch only' network, GBMSM with: (1) a Western European network had higher MICs for ceftriaxone (ß=0.19, 95% CI=0.08 to 0.29), cefotaxime (ß=0.19, 95% CI=0.08 to 0.31) and cefixime (ß=0.06, 95% CI=0.001 to 0.11); (2) a Southern European network had a higher MIC for cefixime (ß=0.10, 95% CI=0.02 to 0.17); and (3) a sub-Saharan African network had a lower MIC for ciprofloxacin (ß=-1.79, 95% CI=-2.84 to -0.74). In women and MSW, higher MICs were found for ceftriaxone in clients with a Latin American and Caribbean network (ß=0.26, 95% CI=0.02 to 0.51). CONCLUSIONS: For three cephalosporin antibiotics, we found Ng strains with slightly higher MICs in clients with partner(s) from Europe or Latin America and the Caribbean. International travel might contribute to the spread of Ng with lower susceptibility. More understanding of the emergence of AMR Ng is needed.

RESUMO

BACKGROUND: Sexual violence remains a persistent and devastating issue in eastern Democratic Republic of Congo (DRC). AIM: To elucidate the sociodemographic, sexual, and obstetrical characteristics associated with the experiences of victims of sexual violence (VSV) among women in the region. MATERIALS AND METHODS: A cross-sectional study was conducted involving 625 women from eastern DRC. Participants provided self-reported data, collected through interviews conducted by trained female interviewers in secure environments. Associations between VSV and various sociodemographic and reproductive health factors were examined. RESULTS: Of the respondents, 26.1% reported experiences of sexual violence. VSV were predominantly younger, with 56.44% aged between 15 and 24 years. Single women comprised 57.67% of VSV, and 37.42% identified as farmers. There were 33.13% of VSV who were illiterate, and 81.60% belonged to the low socio-economic stratum. Early physiological and reproductive milestones characterised VSV: 52.15% experienced menarche at or before 13 years, 34.97% initiated sexual intercourse before age 15, and 18.70% reported their first pregnancy before age 15. Higher nulliparity was observed in VSV (29.45%) compared to non-VSV (9.31%). A lower prevalence of HIV infection was found among VSV (11.04%) relative to non-VSV (25.76%). CONCLUSION: Sexual violence in the eastern DRC exhibits multifactorial associations. Younger women, those in certain occupations, and those with specific reproductive histories appear more vulnerable. The findings underscore the urgency for targeted interventions, enhanced access to education, and improved reproductive health services. Addressing these pressing issues should remain a primary focus in both societal and public health spheres.

RESUMO

Objective: In this study, we aimed to investigate whether age first had sexual intercourse (AFSI) and lifetime number of sexual partners (LNSP) have a direct causal effect on cervical cancer by Mendelian randomization (MR) analysis. Methods: Four approaches were used for MR Analysis, including MR-Egger, weighted method, weighted median, and inverse variance weighted (IVW). MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) as well as MR-Egger regression analysis were conducted to detect whether there was pleiotropy between IVs and outcome, and the outlier SNPs can be detected by MR-PRESSO. The presence or absence of heterogeneity among IVs was suggested according to Cochran's Q statistic. Leave-one-out sensitivity analysis was performed to identify and remove SNPs which could independently change the results. We corrected the results using Bonferroni correction. Results: From the results of IVW, AFSI had a negative effect on cervical cancer (OR = 0.996, 95 % CI: 0.995, 0.998 P = 1.70E-07), which still persisted after Bonferroni correction. However, no causal effect of LNSP on cervical cancer was found according to the IVW results (OR = 1.003, 95 % CI: 1.000, 1.007, P = 0.071). From the results of MR-PRESSO and MR-Egger, no SNP with horizontal pleiotropy between cervical cancer was detected and no SNP was identified as an outlier SNP. Cochran's Q statistic suggested that no heterogeneity existed among IVs of AFSI and LNSP. According to Leave-one-out analysis, the results of MR did not change after excluding any single IV. Conclusion: This MR study reveals that early AFSI has a causal effect on cervical cancer.

RESUMO

Prior research has quantitatively examined why heterosexual men and women report different numbers of lifetime different-sex sexual partners, whereas qualitative work has analyzed how men's masculinity-and to a lesser extent, women's femininity-is tied to gender norms about sexual activity. Less research, however, has quantitatively examined the associations between self-rated masculinity and femininity and reported number of lifetime sexual partners. This brief report uses a large sample of Canadians (n = 2117) to examine how self-rated masculinity and femininity relate to reported numbers of sexual partners among four groups of cisgender people: (1) heterosexual men (n = 972), (2) heterosexual women (n = 979), (3) gay and bisexual/pansexual men (n = 99), and (4) lesbian and bisexual/pansexual women (n = 67). Results demonstrate that self-rated femininity was negatively, and masculinity positively, associated with reported numbers of lifetime different-sex sexual partners among heterosexual women. No significant associations emerged for other groups. The lack of significant associations among heterosexual men may be attributable to the fact that most rated themselves as very masculine and not very feminine, whereas there was more variation among heterosexual women. In contrast, the non-significance among LGBQ women and men could reflect that subcultural norms and practices more strongly shape the number of sexual partners individuals report having in these communities. These results demonstrate that it would be beneficial for researchers to measure self-rated masculinity and femininity in future studies about sexual partnering practices, especially among heterosexual cisgender women.

RESUMO

Resumo Objetivo refletir sobre a possibilidade de utilização dos pressupostos de Imogene King como fundamentação teórica para os cuidados de enfermagem a parceiros sexuais sorodiferentes ao HIV. Método estudo descritivo de caráter reflexivo, com o aporte teórico da Teoria do Alcance de Metas de Imogene King. Resultados as reflexões deram origem a dois eixos de análise: no primeiro, cumpre-se detalhar os pressupostos conceituais de Imogene King e o alcance de metas, e no segundo, explora-se a convergência da teoria de King no cuidado às relações sorodiferentes no que concerne aos seus limites, possibilidades e desdobramentos nos sistemas pessoal, interpessoal e social. Conceitos como percepção, interação e organização formam os eixos centrais dos sistemas e possibilitam a compreensão ampliada das demandas dos parceiros sorodiferentes com vistas ao equilíbrio dos fatores estressores à manutenção da saúde. Considerações finais e implicações para a prática o entendimento dos sistemas abertos aplicados à pessoa que vive com HIV individualmente e na díade com seu parceiro, ambos inseridos em grupos na sociedade, resulta em uma melhor compreensão de suas necessidades e, assim, contribuem com o planejamento de metas direcionadas.


Resumen Objetivo reflexionar sobre la posibilidad de utilizar los supuestos de Imogene King como base teórica para el cuidado de enfermería en parejas VIH-serodiferentes. Método estudio descriptivo de carácter reflexivo, con el aporte teórico de la Teoría del Logro de Metas de Imogene King. Resultados las reflexiones dieron lugar a dos ejes de análisis: en el primero, es necesario detallar los supuestos conceptuales de Imogene King y el logro de objetivos, y en el segundo, se explora la convergencia de la teoría de King en el cuidado de las relaciones serodiferentes en cuanto a sus límites, posibilidades y desarrollos en los sistemas personal, interpersonal y social. Conceptos como percepción, interacción y organización forman los ejes centrales de los sistemas y permiten una comprensión más amplia de las demandas de las parejas serodiferentes con vistas a equilibrar los factores de estrés para mantener la salud. Consideraciones finales e implicaciones para la práctica la comprensión de los sistemas abiertos aplicados a personas que viven con VIH individualmente y en pareja con su pareja, ambas insertadas en grupos de la sociedad, resulta en una mejor comprensión de sus necesidades y, así, contribuye a la planificación de objetivos específicos.


Abstract Objective to reflect on the possibility of using Imogene King's assumptions as a theoretical basis for nursing care in HIV-serodifferent partnerships. Method a descriptive study of a reflective nature, with the theoretical contribution of Imogene King's Goal Attainment Theory. Results the reflections gave rise to two axes of analysis: in the first, it is necessary to detail Imogene King's conceptual assumptions and goal attainment, and in the second, the convergence of King's theory in caring for serodifferent relationships is explored with regard to their limits, possibilities and developments in the personal, interpersonal and social systems. Concepts such as perception, interaction and organization form the central axes of the systems and enable a broader understanding of serodifferent partners' demands with a view to balancing stress factors for maintaining health. Final considerations and implications for practice the understanding of open systems applied to people living with HIV individually and in a dyad with their partner, both inserted in groups in society, results in a better understanding of their needs and thus contributes to planning targeted goals.

RESUMO

Resumo A sífilis gestacional (SG) em adolescentes é um desafio para a saúde pública brasileira, com elevadas taxas de incidência. A testagem, diagnóstico e tratamento dos parceiros sexuais é indispensável para interromper a cadeia de transmissão, mas desde 2017 deixou de ser critério para o tratamento adequado da gestante. Buscamos analisar e sintetizar o conhecimento produzido sobre a atenção à saúde de parceiros sexuais de adolescentes com SG no Brasil. Realizamos uma revisão integrativa nas bases de dados BVS, SciELO e PubMed, selecionando artigos que abordavam SG e/ou sífilis congênita (SC) em adolescentes de 15 a 19 anos e que incluíam informações sobre os parceiros sexuais. Quarenta e um artigos foram analisados compreensivamente com auxílio do software WebQDA e classificados em duas categorias: (a) Abordagem dos parceiros sexuais no pré-natal, e (b) Papel dos parceiros sexuais no ciclo de transmissão da SG e da SC. Os estudos evidenciam que a abordagem do parceiro é deficitária, com ausência de dados sobre o perfil sociodemográfico e informações sobre testagem e tratamento. No âmbito da atenção primária à saúde não se encontram estudos que abordem fatores inerentes ao contexto de vulnerabilidade dos parceiros sexuais em relação ao enfrentamento da sífilis.


Abstract Gestational syphilis (GS) in adolescents is a challenge for Brazilian public health, with high incidence rates. Testing, diagnosis and treatment of sexual partners is essential to interrupt the chain of transmission, but since 2017 it is no longer a criterion for the proper treatment of pregnant women. We sought to analyze and synthesize the knowledge produced about the health care of sexual partners of adolescents with GS in Brazil. We carried out a systematic review in the BVS, SciELO and PubMed databases, selecting articles that addressed GS and/or congenital syphilis (CS) in adolescents aged 15 to 19 years and that included information about sexual partners. Forty-one articles were comprehensively analyzed using the WebQDA software and classified into two categories: a) Approach to sexual partners during prenatal care, and b) The role of sexual partners in the transmission cycle of GS and CS. The studies show that the partner's approach is deficient, with a lack of data on the sociodemographic profile and information on testing and treatment. In the context of Primary Health Care, there are no studies that address factors inherent to the context of vulnerability of sexual partners in relation to coping with syphilis.

RESUMO

Resumo O estudo investiga a associação entre o contexto escolar e a ocorrência de múltiplos parceiros entre adolescentes, considerando as variáveis individuais. Estudo transversal com análise multinível, realizado no período de fevereiro a junho de 2018 com estudantes de 14 a 19 anos. A variável desfecho (múltiplos parceiros sexuais) foi coletada com base no questionário Youth Risk Behavior Survey (YRBS). As variáveis do contexto escolar foram tempo na escola (escola regular vs escola integral/semi-integral) e índice de vulnerabilidade social (IVS) do bairro onde a escola está localizada. De 2.500 participantes, 1.044 foram analisados por serem sexualmente ativos. A maioria dos adolescentes (63,89%) teve dois ou mais parceiros. Estudantes de escola regular (mínimo de 4h diárias) tiveram mais chances (OR 1.47, IC 1.10-1.97) de terem múltiplos parceiros sexuais quando comparados àqueles de escola integral/semi-integral (mínimo de 7h diárias). Porém, não houve associação em relação ao IVS dos bairros das escolas (OR 1.18, IC 0.82-1.70). Maior tempo na escola esteve associado a menor chance de múltiplos parceiros sexuais, enquanto estudar em escolas localizadas em bairro de alta vulnerabilidade não esteve associado à ocorrência de múltiplos parceiros sexuais entre adolescentes.


Abstract The objective was to investigate the association between the school context and the occurrence of multiple partners among adolescents, considering individual variables (age, gender, Bolsa Família, LGB, early sexual initiation and use of alcohol or drugs in the last sex). Cross-sectional study with multilevel analysis carried out in 2018 with adolescent students from Olinda, Brazil. The variable (multiple partners) was collected based on the 'Youth Risk Behavior Survey' questionnaire. School context variables were time in school (regular school vs. full/semi-full school) and the Social Vulnerability Index of the school district. Of 2,500 participants, 1,044 were analyzed for being sexually active and most had two or more partners (63.89%). Regular school students were more likely (OR 1.47, CI 1.10-1.97) to have multiple sexual partners compared to those in full-day schools/half-day schools. However, no association was found in relation to the SVI of the schools' neighborhoods (OR 1.18, IC 0.82-1.70). More time spent at school was associated with fewer chances of multiple sexual partners, while studying in schools located in highly vulnerable neighborhoods was not associated with the occurrence of multiple sexual partners among adolescents.

RESUMO

Resumen OBJETIVO: Determinar la prevalencia de alteraciones en la citología anal, infección anal por virus del papiloma humano y en la neoplasia intraepitelial anal; además, explorar los factores de riesgo y los serotipos asociados en pacientes con lesión intraepitelial cervical de alto grado, a partir de la hipótesis de que esta población tiene mayor riesgo de lesiones precursoras o cáncer anal. MATERIALES Y MÉTODOS: Estudio observacional, descriptivo y transversal, con componente analítico, efectuado en pacientes con diagnóstico de lesión intraepitelial cervical de alto grado (LIEAG) en dos instituciones de salud: una privada y otra pública de Bogotá, atendidas entre enero de 2017 y febrero de 2018. Se efectuó un muestreo no probabilístico, por conveniencia. RESULTADOS: Se incluyeron 119 participantes, en 4 de ellas se evidenció, en la citología anal, el hallazgo de células anormales en el tejido que reviste la parte exterior del cuello uterino. Se encontraron 14 anoscopias anormales que dieron una prevalencia de neoplasia intraepitelial anal del 6.7%. Siete eran neoplasia intraepitelial anal de bajo grado y una de alto grado. Se encontró infección por VPH anal en 45 participantes (37.8%) y se detectaron genotipos de VPH-AR en 29 participantes (24.4%). Más de 3 compañeros sexuales, más de 3 hijos y tener menos de 21 años antes del primer embarazo tuvieron un valor de p < 0.05 que confiere mayor riesgo de infección por VPH anal. CONCLUSIÓN: Es importante establecer en Colombia protocolos para la detección de la neoplasia intraepitelial anal en grupos de alto riesgo, como las pacientes con neoplasia intraepitelial cervical o cáncer de cuello uterino, e incentivar el adiestramiento en la anoscopia de alta resolución en especialistas relacionados con el diagnóstico de patología anogenital.


Abstract OBJECTIVE: To determine the prevalence of alterations in anal cytology, anal human papillomavirus infection, and anal intraepithelial neoplasia, and to explore the risk factors and associated serotypes in patients with high-grade cervical intraepithelial lesion, based on the hypothesis that this population is at higher risk for precancerous lesions or anal cancer. MATERIALS AND METHODS: Observational, descriptive, cross-sectional study, with analytical component, performed in patients diagnosed with high-grade cervical intraepithelial lesion (HG-CIL) in two health institutions: one private and one public in Bogota, visited between January 2017 and February 2018. A non-probabilistic sampling was performed, by convenience, with a sample calculated in 124 patients. RESULTS: 119 participants were included, in 4 of them it was evidenced in the anal cytology, the finding of abnormal cells in the tissue lining the outside of the cervix. Fourteen abnormal anoscopies were found, giving a prevalence of anal intraepithelial neoplasia of 6.7%. Seven were low-grade anal intraepithelial neoplasia and one was high-grade. Anal HPV infection was detected in 45 participants (37.8%) and HR-HPV genotypes were detected in 29 participants (24.4%). More than 3 sexual partners, more than 3 children and being younger than 21 years before first pregnancy had a p-value < 0.05 conferring an increased risk of anal HPV infection. CONCLUSION: It is important to establish protocols in Colombia for the detection of anal intraepithelial neoplasia in high-risk groups, such as patients with cervical intraepithelial neoplasia or cervical cancer, and to promote training in high-resolution anoscopy in specialties related to the diagnosis of anogenital pathology.

RESUMO

Background: Limited studies have explored the association between sexual factors [age at first sexual intercourse (AFS) and lifetime number of sexual partners (LNSP)] and cardiovascular diseases (CVDs), leaving the causality inconclusive. Methods: We performed a bi-directional Mendelian randomization (MR) study to investigate the causality between sexual factors and CVDs, including coronary artery disease, myocardial infarction, atrial fibrillation (AF), heart failure (HF), and ischemic stroke (IS). Single-nucleotide polymorphisms (SNPs) for sexual factors were extracted from the UK Biobank. Statistics for each CVD were derived from two different databases. MR estimates were calculated per outcome database and were combined through meta-analysis. Several complementary sensitivity analyses were also performed. Results: The primary analysis suggested that AFS was causally associated with the risk of CVDs; the odds ratios (ORs) ranged from 0.686 [95% confidence interval (CI), 0.611-0.770] for HF to 0.798 (95% CI, 0.719-0.886) for AF. However, the association between AFS and IS (OR, 0.844; 95% CI, 0.632-1.126) was not consistent in the meta-analysis after excluding SNPs related to confounders. Moreover, non-significant associations were found between LNSP and CVDs. Reverse direction MR analysis showed that CVDs were not associated with sexual factors. Conclusions: Genetic evidence suggested that AFS was causally associated with the risk of CVDs except for IS, whereas non-significant association of LNSP with CVDs was detected. Further investigation into AFS could be warranted in preventing the progression of CVDs.

RESUMO

HIV is recognised as a multifaceted chronic disease, bearing psychosocial consequences that potentially impact on the personal and social well-being of those living with it. Adolescents and youth bear a significant proportion of the burden of the HIV epidemic but they have low rates of disclosure of their HIV status. This study aims to determine the views of adolescents living with perinatally acquired HIV on HIV status disclosure among 361 adolescents aged 15-19 in Eswatini. A cross-sectional study was conducted on adolescents who already knew their status, and data were collected using a structured questionnaire. A majority of the participants, 55% (n = 200), were females, and 44% (n = 160) were males. A low number of adolescents (22%) had disclosed their HIV status to anyone. Adolescents who found it difficult to understand disclosure themselves had low levels of onward disclosure (27%) compared to adolescents who better understood the disclosure event. Our results revealed that adolescents' prevalence of HIV status disclosure was low. This raises concerns as some of the adolescents were in relationships with partners who were not aware of their status. However, older adolescents displayed some level of disclosure self-efficacy in that a higher proportion of them disclosed better than younger adolescents.
