Abstract:

The national reported rates of sexually transmitted infections (other than HIV/AIDS) in Ireland have been increasing over the last decade of the 20^th century. Medical professionals and epidemiologists consider the rates of STIs as indicators of the proportion of the population engaging in 'high risk' behaviour. According to this hypothesis, an increase in reported rates reflects an increase in 'high risk' behaviours. This thesis will examine this relationship and determine the reasons for the increased reported rates in Ireland. This will involve an investigation into Irish sexual behaviours and attitudes, thus giving an insight into Irish sexuality, which has previously attracted little sociological interest. Evidence in regard to Irish sexuality and sexually transmitted infections is limited. In the absence of longitudinal data on sexual behaviours and a national survey on STIs and risk-taking sexual behaviours, the question of the rising rates has to be addressed by collating available data from different sources. This involves: (1) the use of epidemiological and GUM clinics' information, (2) a socio-historical account of Irish sexuality and sexually transmitted infections and (3) a comparative analysis of Irish sexual behaviours and attitudes with four other countries utilising the International Social Survey Programme's 1994 dataset, Family and Changing Gender Roles II. It is concluded that the increasing reporting rates of STIs are not being directly caused by accompanying increases of 'high risk' sexual behaviours in the general population but are produced by a number of factors including a growing public openness about sexuality and sexual health awareness.

Abstract:

Sexually transmitted infections (STIs) have important consequences for individuals and society. Extensive literature has shown that various individual factors impact STIs. However, much less is known about their structural causes and how they affect sexual behavior and sexual network formation. In the first two chapters of this dissertation, I investigate how sex ratios and ethnic divisions affect sexual activity and the spread of STIs. In the third chapter, I analyze the effect of ethnic-based romantic homophily on STIs. I provide a brief description of each chapter below. Chapter 1. We extend a theory of fidelity in a two-sided economy, and empirically discriminate between different rationales of sexual network formation by testing their implications for how sex ratios affect sexual activity, relationship stability, and the spread of sexually transmitted diseases in men versus women. We use a unique individual-level dataset in combination with census data from England and Wales, a setting where adult women outnumber adult men. Exploiting variation in cohort/ethnicity/region-specific sex ratios as a quasi-natural experiment, we find that a decrease in sex ratio imbalance decreases sexual infidelity and the number of serial partners, and increases the likelihood of safe sex. This in turn reduces the likelihood of acquiring a range of sexually transmitted infections and diseases, including chlamydia, gonorrhoea, genital warts, and herpes. Consistent with the rationale underlying the formation of egalitarian (in)fidelity networks, the effects of the sex ratio on sexual activity are larger for men compared to women, while its effects on sexual diseases are larger for women compared to men. The causality of these effects is established using classical and recent instrumental variables approaches and various robustness checks. For falsification, we show that sex ratios have no impact on several "atheoretical" health conditions, such as Parkinson's disease, chronic lung disease, heart attack, stroke, and diabetes, which do not arise from sexual interactions. Chapter 2. In societies organized around distinct racial and ethnic groups, limited communication between these groups might increase the search cost of sexual partners outside of own group, leading to racially segregated sexual networks and low risks of sexually transmitted diseases. At the same time, because sexual infidelity is more likely to be discovered when the cheated-upon individuals are co-ethnics, individuals in multiracial societies might find it cheaper to select sexual partners from diverse ethnic groups to hide their infidelity, which would lead to large interethnic sexual networks and high risks of STIs. We test these conflicting hypotheses by analyzing the causal effect of neighborhood-level racial diversity on sexual activity and STIs, using unique individual-level data from England, Wales, and Scotland. We find that individuals residing in multiracial neighborhoods have a greater number of sexual partners and are more likely to be infected with a wide range of STIs than their counterparts residing in more racially homogeneous neighborhoods. We use traditional and new instrumental variables approaches and various robustness checks to establish causation. Analyzing mechanisms, we find that within racially diverse neighborhoods, individuals who select sexual partners from diverse racial groups are more likely to be infected with STIs, holding the number of partners and other individual characteristics fixed. For falsification, we conduct a reverse-placebo test showing that racial diversity has no effect on a wide range of health conditions that do not arise from sexual interactions. From a policy perspective, our analysis implies that policies that promote racial and ethnic integration are likely to reduce unhealthy sexual activity and the spread of STIs in racially heterogeneous societies. Chapter 3. A classical hypothesis in social network theory holds that central individuals are more likely to receive and spread information than are their peripheral counterparts. We test this hypothesis in the context of sexual networks and sexually transmitted diseases, using data from the United Kingdom. Romantic homophily - the tendency to select sexual partners with similar ethnic background - is used as a measure of the extent to which an individual is peripheral in a sexual network. We find that more sexually homophilous individuals have a lower risk of sexual infections. This effect is causal, and larger for women, Whites, and heterosexuals.

Abstract:

Increases in the rates of sexually transmitted infections (STIs) suggest that control programs may not be targeting the population responsible for the spread of STIs - core groups. The objective was to examine STI transmission within these groups using both traditional epidemiology and social network analysis. Routine partner notification data, supplemented with more detailed voluntary information, was collected from individuals diagnosed with, or exposed to a STI in Manitoba. Groups of individuals were identified (n=2,508), and their profiles described. Larger groups (size > 15) had more repeat cases, and contacts that were repeatedly named. Three different groups were identified, containing individuals which differed demographically and clinically. This study uniquely identified same-sex partnerships within larger groups. A greater understanding of disease transmission patterns within these groups will clearly aid in the development of targeted education and prevention programs for all STIs.

Abstract:

Bibliography: p. 171-172.
South Africa's HIV epidemic has increased rapidly over the last 10 years, and developing effective strategies to curb it is a priority. The presence of other sexually transmitted infections (STIs) facilitates the sexual transmission of HIV, and the control of STIs has been shown to be an effective way of reducing HIV incidence. One component of the process of STI control is partner notiﬁcation: a process whereby the sexual partners of patients who have been diagnosed with an STI are informed of their exposure to infection and of the importance of obtaining effective treatment. Partner notiﬁcation is one of the two strategies to reach and treat asymptomatic and unrecognised STIs, which are highly prevalent in South Africa. Unfortunately, current partner notiﬁcation strategies are not very effective, and there is a need to improve their effectiveness. This thesis investigates strategies to improve partner notiﬁcation in South Africa. This aim is achieved through three separate studies. The ﬁrst is a systematic review of published and unpublished randomized controlled trials (RCTs) conducted around the world, comparing the effects various partner notiﬁcation strategies, in an attempt to uncover evidence of effective strategies. The review uses methods advocated by the Cochrane Collaboration. Eleven RCTs were found, including 8014 participants, only two of which were conducted in developing countries. The review found moderately strong evidence that either provider referral alone, or the choice between patient and provider referral, or contract referral, when compared with patient referral, improved partner notiﬁcation. This evidence is of limited value in South Africa, where public health services have not been able to implement provider or contract referral due to the prohibitive staffing costs involved. The review also found that verbal, nurse-given health education together with intense patient-centred counselling by lay workers, when compared with standard care results in small increases in the rate of partners treated. The review concludes that there is a need for evaluations of patient education interventions (including audiovisual presentations), of interventions combining provider training and patient education, and for evaluations to be conducted in developing countries. Further, there is a need to measure potential harmful effects, such as domestic violence, to ensure that partner notiﬁcation does more good than harm.

Abstract:

Background. In sub-Saharan Africa, which has the highest prevalence of HIV-1 worldwide, most newHIV-1 infections occur by sexual transmission to women. Recent studies in non-human primates have demonstrated that pro-inflammatory cytokine production in the genital tract is necessary for immune cell recruitment and establishment of simian immunodeficiency virus (SIV) infection following vaginal inoculation. The aims of this study were to evaluate the relationships between inflammation in the female genital tract and (i) susceptibility to HIV-1 infection and (ii) subsequent disease progression in women who became infected. Additionally, genital inflammation was investigated as a mechanism for breakthrough HIV-1 infections in women who became infected even though they were using 1% tenofovir (TFV) microbicide. In the systemic compartment, the level of T cell activation and soluble markers of immune activation during HIV-1 infection are associated with disease outcome. Therefore, the relationships between plasma cytokine concentrations during early HIV-1 infection and disease progression were evaluated Methods. The participants of this study included 230 HIV-uninfected women from the CAPRISA 002cohort who were followed longitudinally for HIV-1 infection, 49 women who were enrolled during acuteHIV-1 infection and followed until 12 months post-infection and 166 HIV-uninfected women who were enrolled in the CAPRISA 004 1% TFV microbicide trial (62 of whom later became HIV-1-infected).Cytokine concentrations were measured in cervicovaginal lavage (CVL) and plasma samples from these women using Luminex and ELISA.

Abstract:

The aims of this thesis were to expand the knowledge about sexual and reproductive health among urban Ugandan youths, living in a slum, and to evaluate the national flow-chart for management of the abnormal vaginal discharge (AVD) syndrome in adolescent girls. Data collection included individual interviews, focus-group discussions and clinical investigations with tests for chlamydia trachomatis (CT), neisseria gonorrhoea (NG), trichomonas vaginalis (TV), syphilis, and HIV infection. Poverty, peer pressure and gender power imbalance were obstacles to safe sexual practices: to abstain from sex, be faithful or to use condoms. Prevalence among the 199 female and 107 male adolescents for CT, NG, TV, syphilis and HIV was 4.5%, 9.0%, 8.0%, 4.0% and 15.2% for females and 4.7%, 5.7%, 0%, 2.8% and 5.8% for males. The national AVD flow-chart had a sensitivity of 61%, a specificity of 38.5% and a positive predictive value (PPV) of 11.6%. A flow-chart using risk factors, rather than symptoms, implicated a sensitivity/specificity and PPV of 82.6%/47% and 17.3% respectively. Socially disadvantaged females had a high risk to be HIV infected and HIV infection was associated to other STIs. Females were more likely than males to have any of the infections studied. Voluntary counselling and testing (VCT) for HIV was considered as helpful in preventing the spread of HIV. Obstacles for testing were: lack of time and money, fear of stigmatisation and fear that the knowledge of HIV positive status could shorten someone's life. An alternative flow-chart for management of AVD among adolescent girls should be evaluated. Girl's opportunities for education and income generating work should be a priority. VCT services for young people should be made accessible in terms of cost, time and quality of counselling.

Abstract:

Sexually transmitted infections (STIs) disproportionately impact non-Hispanic blacks in the United States. Racial differences in sexual networks can contribute to these disparities. Racial residential segregation, the separation of racial groups in a residential context, is a community factor known to influence sexual networks and has been associated with negative health outcomes. Our objective was to examine the association between racial residential segregation (henceforth, referred to as segregation), risky sexual behavior, concurrent partnerships, and STI diagnoses among non-Hispanic blacks. Demographic, sexual behavior, and STI diagnosis data for non-Hispanic blacks 15–44 years of age were obtained from the 2006–2010 National Survey of Family Growth. Segregation and community poverty data were obtained from the U.S. Census. Five distinct dimensions measured segregation, each with a representative index. Multilevel logistic regressions were conducted to test how each of the five indices were associated with risky sexual behavior, concurrent partnerships, and STI diagnoses. Risky sexual behavior results showed 16.1% (n=588) of participants engaged in risky sexual behavior. The association was stronger for the absolute centralization (adjusted odds ratio [aOR] 2.07; 95% confidence interval [CI] 2.05 – 2.08) and relative concentration indices (aOR 2.05; 95% CI 2.03 – 2.07). This suggests risky sexual behavior is most strongly associated with segregation in neighborhoods with a high density of non-Hispanic blacks and accumulation of non-Hispanic blacks in an urban core. STI diagnosis results showed 7.4% (n=305) of participants reported a STI diagnosis, and segregation was associated with STI diagnosis. The association was strongest measured with the dissimilarity index (aOR 2.41; 95% CI 2.38 – 2.43) and stronger for males. Concurrent partnerships results showed 15.6% (n=645) of participants reported concurrent partnerships. Multilevel analyses showed segregation to be associated with concurrent partnerships with the association strongest measured with the dissimilarity index. Segregation acted as a risk and a protective factor with risky sexual behavior, concurrent partnerships, and STI diagnosis, depending on the segregation measure. Additional work is needed to understand the mechanisms of how specific segregation dimensions influence risky sexual behaviors and sexually transmitted infections.

Thesis (M. Med.(Family Medicine))--University of Limpopo (Medunsa Campus), 2010.
Background: The control of STIs remains a priority for the WHO. Health – seeking and sexual behaviors are important elements in the control of sexually transmitted infections (STIs). Aim: To assess health seeking behavior in relation to STIs amongst community members of Nkomazi East area of Mpumalanga who use Tonga hospital’s feeder clinics and comprehensive health centers. Study Design: This was a quantitative research carried out as a non-experimental, descriptive cross-sectional survey employing the use of questionnaires for data collection. Questionnaires covering social, demographic, and healthcare-seeking and sexual behaviour information were administered to 332 patients attending primary care clinics in Nkomazi East area of Mpumalanga. Results: Majority of the participants were single, literate, unemployed blacks aged between 16 – 23 years (43.7%). Participants displayed an exceptionally high STI knowledge with urethral discharge, painful micturition, vaginal discharge and lower abdominal pain the most recognised STI symptoms. All the participants (100%) sought help on perceiving that they have an STI. Preferred source of help is the public health sector with traditional healers also finding some relevance. While compliance to treatment is largely satisfactory, ongoing unsafe sexual practices with active STI seem to be common place. Conclusion: Participants displayed a high knowledge of STI symptoms and signs. Public health facilities were the preferred source of health. Health seeking seemed to be influenced by multiple factors. Financial consideration was not much of a factor while seeking help compared to accessibility to health facility and stigma or shame. Belief system, influence by family members, friends and partners were also important factors influencing health seeking behaviour

Abstract:

Presently, clinical management of sexually transmitted infection (STI) is performed empirically, in the absence of microbiological diagnosis and consequentially the use of suboptimal antimicrobial therapy. Current diagnostic methodologies cannot facilitate the polymicrobial detection required to identify the potential multiple organisms that contribute to STI's. In order to meet this requirement a PCR coupled micro array capable of detecting the presence or absence of 23 organisms relevant to STI was developed and evaluated. This method was applied to explore the differential organism prevalence in 129 first void urine specimens in patients of varying symptomology, revealing the absence of Lactobacilli may be associated with urethritis. Findings of this study also documented the inadequacy of Gram stained urethral smear (GSUS) for identification and stratification of urethritis cases. Performance of rapid automated urine flow cytometric (AUFC) of urinary white cell count (UWCC) as a potential replacement for GSUS was validated in a separate study of male clinic attendees (n=436). UWCC testing demonstrated significantly enhanced specificity when compared to GSUS; universal application of this method would have significantly improved identification of urethritis cases at the point of care. The degree of urethral inflammation implied by UWCC analysis exhibited a stronger association with pathogen load of Mycoplasma genitalium when compared to Chlamydia trachomatis. A notably high prevalence of azithromycin resistant M. genitalium infection was observed amongst study participants; subsequent phylogenetic analysis implied this finding was applicable beyond this patient population. The findings of this thesis contribute new approaches to tackling the inadequacies of current empirical approaches to STI management. Modification of treatment guidelines in light of these findings and adoption of UWCC testing may improve treatment efficacy and enhance detection of nongonococcal urethritis and related syndromes. Results observed also provide an insight into the pathogenic mechanisms of different STI organisms in relation to host inflammatory responses.

Abstract:

Variations in the incidence and prevalence of diagnosed sexually transmitted infections (STIs) across racial and ethnic groups have been described in many western industrialised settings. The reasons for these variations are unclear. However, an understanding of their determinants is required in order to develop and refine targeted HIV/STI prevention interventions. This thesis brings together a collection of studies exploring the relationship between ethnicity and the epidemiology of STIs (including HIV infection). It is divided into three main sections. Section one outlines the aims and objectives of the thesis explores concepts of race and ethnicity provides an historical and demographic overview of Black and ethnic minority communities in Britain and critically reviews and summarises the research evidence in this field. Section two outlines the rationale, methodology and outcomes of four studies developed to explore and quantify the nature and range of ethnic variations in sexual health outcomes in Britain. The concluding section summarises key themes arising from this work and relates findings back to set objectives. This thesis confirms the existence of variations in the prevalence of diagnosed STIs among Britain's main ethnic groups. The inequalities are found across a variety of settings, for both reported and prevalent diagnosed infections. Compared with the ethnic majority, adverse sexual health outcomes are more prevalent among Black British ethnic groups, and less so among Indians and Pakistanis. The collated studies confirm that ethnic differences in the prevalence and distribution of high-risk behaviours exist (particularly among men) and may, to a large extent, explain the variations in adverse outcomes. However, behaviour alone cannot account for the observed differences. Other factors, including patterns of health-seeking behaviour, genetic susceptibility, patterns of sexual mixing and background prevalence of disease also contribute, to the observed variations in incidence. Recommendations for future studies and interventions in this field are made.

Abstract:

Adolescents continue to be at increased risk for contracting sexually transmitted infections (STI's). This research study describes the perception of barriers that providers in the Tampa Bay area encounter when implementing primary STI prevention programs for adolescents within the community context. This study used semi structured interviews to explore perceived barriers for implementing primary such programs for adolescents in the Tampa Bay area programs. Participants reported faith based institutions/churches and schools as common sectors for presenting a variety of barriers for implementing their program. Perceptions of barriers were described as, the need to tailor program messages and presentations based on restrictions from school officials and parent's opposition to the program; the lack of appropriate places for program activities and distribution of program materials. Other issues that were identified by several participants were lack of political support for programs at the national level and the need for more funding to administer programs.

Abstract:

The overall aim of this thesis was to inestigate Swedish adolescents' perceptions and behaviours regarding sexual risk taking. Specific objectives were to explore teenagers' perceptions of contraceptive use, unintended pregnancy, and abortion; teenage girls' experiences of decision making process and support connected to abortion; and male adolescents' perceptions of sexual risk taking and barriers to practicing safe sex. Another objective was to evaluate the effect of advance provision of emergency contraceptive pills to teenage girls. The methodologies included focus group discussions, in-depth interviews, and a randomized controlled trial.

Among the adolescents in our studies, teenage parenthood was generally viewed as a "catastrophe", and the majority expressed supportive attitudes towards abortion (studies I-IV). Occasions of failure to use contraceptives were common, especially when sex was unplanned (studies I-V). Pregnancy prevention was perceived as the woman's responsibility. However, many girls were reluctant about using homonal contraceptives due to worries about negative side effects (I, III). Initiating condom use was difficult for girls, as well as for boys, for a number of reasons (I-IV): fear of ruining an intimate situation, associations with disease, distrust, pleasure reduction, and (for the boys) the fear of loosing one's erection. Males generally perceived personal and partner-related risks connected to unprotected intercourse as low. Few males were worried that an unintended pregnancy would be carried to term, and the majority would urge the girl towards abortion if she seemed ambivalent (II, IV). Girls viewed the abortion decision as a natural, yet difficult choice, strongly influenced by attitudes of partners, parents, peers and societal norms (III). Teenage girls provided with emergency contraceptive pills in advance used it more frequently and sooner after unprotected intercourse compared with controls, without jeopardising regular contraceptive use (V).

Abstract:

There is a paucity of research on the risk for sexually transmitted infections (STIs) and sexual behavior among general populations of men. Research with male populations predominantly has focused on those subgroups considered to be at high risk of disease transmission, such as gay and bisexual men, injection drug users, and adolescents/young adults. Considerably fewer studies have examined factors among men, in general, and heterosexual men, specifically. Therefore, I conducted analyses with a cross-national sample of adult, sexually active men in Brazil, Mexico, and the United States to investigate sexual behaviors and risk factors associated with the human papillomavirus (HPV) and other STIs. The research questions were: 1) How does sexual risk differ among men residing in Brazil, Mexico, and the US by age cohort?; 2) Do men's sexual behaviors change after being tested for HPV and other STIs?; and 3) Do men's sexual behaviors change after being informed of diagnosis with HPV and other STIs? These research questions were explored through a quantitative assessment of secondary data collected through a risk factor questionnaire administered using computer assisted self-interviewing. The study findings underscore the need for public health interventions to address STI risk and transmission among men across the lifespan. Additionally, this study revealed the potential of STI testing as an effective strategy to reduce sexual risk-taking among men. While this research identifies key issues of importance in improving men's sexual health, additional research is needed to provide an enhanced contextual understanding of socio-cultural, interpersonal, and community level factors that affect sexual behaviors and decision-making among men.

Abstract:

Chlamydia trachomatis (Chlamydia) is the most common sexually transmitted infection diagnosed in genitourinary medicine (GUM) clinics and affects one in ten sexually active young people. Neisseria gonorrhoeae (gonorrhoea) is the second most common. They are asymptomatic in at least three-quarters of patients. Untreated infection can lead to serious health problems; including pelvic inflammatory disease and infertility in women. In men, it can cause urethritis and Reiter‟s Syndrome (arthritis). The number of diagnoses of uncomplicated chlamydia in GUM clinics in England increased by 288% between 1995 and 20061. Co infection with chlamydia and gonorrhoea is not uncommon. Up to half of patients diagnosed may be infected with both pathogens and, therefore, it is important to test sexually active individuals for both chlamydia and gonorrhoea using a multiplex system2. Electrochemical detection of specific DNA sequences offers advantages over established fluorescence techniques; including cost and ease of miniaturisation. The electrochemical gene sensor described here uniquely utilises enzymatic T7 Exonuclease digestion to generate ferrocenylated oligonucleotide fragments in a matched (gene sequence presence) sensor. These fragments exhibit a characteristically high response upon electrochemical analysis, using Differential Pulse Voltammetry and have been designed based on the ability to „tune‟ the oxidation potential of ferrocene by using electron-withdrawing and electron-donating substituent groups. Ferrocenylated oligonucleotide labels have been synthesised, each with a characteristic oxidation potential. Results from a study of the adsorption and electron transfer kinetics of T7 exonuclease - digested and undigested oligonucleotide redox probes at screen-printed carbon paste electrode (SCPE) surfaces will be considered as a basis for the assay discrimination. The high selectivity of the T7 Exonuclease digest is demonstrated using the ferrocenylated oligonucleotides and a triplex genomic electrochemical assay for the detection of Chlamydia trachomatis, Neisseria gonorrhoeae and the human 7 beta-actin gene as an internal control for the assay using clinical samples will be presented.

Abstract:

The thesis covered validation of quantitative polymerase chain reaction (qPCR) assays for the detection of the genital Mollicutes - M.genitalium, M.hominis, U.urealyticum, U.parvum, and relevant non Mollicute organisms found in the urogenital tract specifically T. vagina lis, G. vaginalis and S.agalactiae; a novel qPCR was developed for G.vaginalis. The assays were applied to (a) residual anonymised specimens from a Genitourinary Medicine clinic and (b) placental specimens collected with informed consent in pregnancies presenting in preterm labour; both approaches had appropriate ethical approval. The analysis allowed the prevalence, clinical significance and synergistic relationships of genital Mollicutes to be assessed in different anatomical sites (urethra, vagina, rectum) and different clinical conditions. The qPCR assays were highly reproducible, provided new observations and allowed novel findings to emerge from the overlapping stUdies. Mollicute infections are common and therefore commonly missed by current testing algorithms for STls. M.genitalium and U.parvum were significantly associated (p<0.001 and p=0.03 respectively) with non-chlamydial non-gonococcal urethritis in men attending GUM. U.parvum, which is a bacterial commensal of the vaginal micro-flora, showed a significant association with chorioamnionitis (p=0.002) in women delivering preterm and also demonstrated growth synergy (p=0.017) with G.vaginalis in bacterial vaginosis. A further synergy involving M.hominis and G.va!~inalis (p <0.0001 ) was also demonstrated in bacterial vaginosis and in the rectum of men who have sex with men. The association with preterm labour and with bacterial vaginosis suggests that disruption of the vaginal micro-flora in pregnancy could trigger serious obstetric complications involving commensal bacteria. It could also be speculated that the synergistic bacterial overgrowth seen in samples from the rectal mucosa is a factor in HIV transmission across an inflamed surface. The prevalence data and associations with important clinical conditions would support the need for more research on the role of Mollicutes and co-infection in both STls and infections in pregnancy.

Abstract:

Viral sexually transmitted pathogens, including herpes simplex viruses (HSV) and human immunodeficiency virus (HIV) are a major global health problem. In this study, genital mucosal immune response against viral sexually transmitted infections (STI), particularly in the early phase were investigated. Vaginal infection with HSV-2 in a mouse model results in epithelial layer breakdown and uncontrolled spread of the virus into the CNS. Therefore, it does not accurately reflect HSV-2 infection in humans. As such, a murine model of non-lethal STI using the flavivirus West Nile virus (WNV) has been developed, which is characterised by mild and self-limiting viral infection. Infection with both WNV and HSV-2 resulted in acute recruitment of macrophages, dendritic cells (DC), neutrophils and lymphocyte subsets from the bone marrow to the vagina and draining lymph nodes (ILN). Of interest, clusters of CD11c+ cells (but not CD11b or F4/80) were observed in close association with foci of epithelial cell infection. Although the infiltrating leukocytes in the vagina and ILN of C57BL/6 (Th1-prototype) and BALB/c (Th2-prototype) mice were comparable, the chemokines regulating DC and macrophage migration were differentially expressed in the two strains. In particular, CCL20 was only expressed in BALB/c mice, while CCL2 was expressed in the vagina of WNV-infected C57BL/6 mice. The reduction of several leukocyte subsets, including CCR2+ macrophages were observed after systemic CCL2 neutralisation, while, anti-CCL20 administration resulted in increased WNV infection in the vaginal epithelium. Moreover, macrophage migration was investigated using polystyrene beads. Interestingly, beads+ cells were found to accumulate in the spleen, suggesting several subsets of macrophages, DCs, neutrophils and lymphocytes become trapped and thus prevented from infiltrating the vagina and ILN. In addition, vaginal infection was associated with a dramatic upregulation of enzymatically active IDO. Thus, a possible antiviral or immunosuppressive role of IDO in this model was further investigated.

Abstract:

Sexually transmitted infection (STI) prevalence rates are increasing in the United States and globally. Education has been found to be an important strategy for increasing STI testing and treatment rates among sexually active young adults. The goal of this project was to develop an interactive educational game suitable for young adults to decrease the social and economic burden of STIs. The health belief model informed the project. A moderated usability evaluation was conducted using the concurrent think-aloud technique. The participants (N = 5) were a purposive sample of professionals who played the interactive game and then completed Schnall, Cho, and Lie’s Health-Information Technology Usability Evaluation Scale instrument. The findings revealed the necessity of (a) an introduction screen, (b) a reward system for correct answers, and (c) avatars, while also highlighting that (d) the effect on indicator value bars is difficult to understand and (e) the timer led to a feeling of being rushed. The Cronbach’s alpha for the participant group was 0.798, the subscale “Perceived Ease of Use” achieved an alpha level of 0.815, and the subscale “Perceived Usefulness,” 0.762. Refinements to the game based on these data might help to ensure that use of the interactive game contributes to social change by increasing knowledge of STIs in the young adult population.

Abstract:

Sexually transmissible infections (STIs), one of the major preventable health problems affecting the Australian population, are often asymptomatic and, if undetected, can cause sub-fertility, infertility and chronic morbidity. In addition to these significant and costly consequences, STIs increase the risk of transmission of HIV. Given that 80% of Australian patients attend their General Practitioner (GP) each year, GPs are well placed to have a significant impact on STI transmission by diagnosing and treating both asymptomatic and symptomatic disease. Good professional practice would suggest that all GPs will undertake certain actions when they are consulted by a patient who either has symptoms of an STI or who appears to be at risk of acquiring an STI. This expectation is based on the premise that all GPs share the same detailed knowledge of STI risk factors and symptoms. It assumes that they will have no difficulty in eliciting such information from the patient, that the patient will comply with STI testing and treatment and that the patient will return for follow-up, to ensure that they and their sexual partners have been adequately treated. Given the constraints of the real world in which general practice exists, the sensitive nature of sexual health, and the stigma associated with STIs, there are many barriers to achieving such an outcome. My own previous research has highlighted some of the difficulties experienced by GPs in the area of STI control. This study has used data from four different sources (policy and stakeholder documents, literature, key informant interviews and my own past research) to examine ideal practice and actual practice in the prevention and treatment of STIs. A number of discrepancies were identified, and from these arose a series of recommendations for ways of making STI control in general practice less complex. To ensure that the results of the study were firmly embedded in the reality of general practice, comments on the recommendations were sought from GPs employed in a variety of practice settings, including those with low STI caseloads. These comments were used to modify the recommendations to ensure they would offer a practical and effective contribution to STI control in Victoria.

Abstract:

Introduction: Youth (15-24) have the highest prevalence of sexual transmitted infections (STI) among all the age groups and this has been attributed to high sexual risk behaviour and low condom use in this group. The use of condoms by youth is negotiated through a complex array of personal and social factors. Aim: The aim of this study was to explore the perceptions of Swedish youth on the factors that affect their use of condoms to protect against STI. Methodology: The data collection was done over a period of 3 months using semi-structured interviews and focus group discussions (FGD) and the collected data was analysed with thematic analysis. Findings: Participants perceived that different factors across intimate social circle, community and access to condoms influence the use of condoms by youth in Sweden. The lack of information from the media, embarrassment as a barrier to obtaining condoms and the influence of parents on condom use were prominent findings. Conclusion: Efforts to improve condom use by youth will benefit from exploring the different factors that inform youth’s perceptions on condom use. Opportunities for improvement identified in this study include the installation of condom vending machines, promoting condom use through the mass media and parents discussing condoms with their children.

Abstract:

Philosophiae Doctor - PhD
The sexual behaviour of youths is believed to play a role in the spread of SexuallyTransmitted Infections (STIs) and Reproductive Tract Infections (RTIs). This study examinesthe determinants of youth sexual behaviours and knowledge of reproductive tract infections (RTIs) and sexually transmitted infections (STIs) in Malawi. It explores rural/urbandifferentials in sexual behaviours using indicators such as early sexual initiation, multiplesexual partnerships, and non-use of condoms, in order to establish policy recommendationstoward improving sexual behaviour among youths. The Malawi Demographic Health Survey2010 data was used. Out of a sample of 2987 males and 9559 females aged 15-24 years,5652 females and 1405 males (condom use), 675 females and 511 males (inconsistentcondom use), 6470 females and 2026 males (multiple sexual partnerships (MSP)), and 15217females and 1405 males (early sexual debut) were filtered in the study.Chi-square and logistic regression techniques were performed to test for association betweensexual behaviour indicators and socio-demographic variables. The prevalence of non-use ofcondom was higher among catholic females (OR=1.11), lower among Muslim males (OR=0.81) and higher among CCAP females (OR=1.19). Muslim females were (OR=1.42) more likely to initiate sexual activities early, while Muslim males were (OR= 0.57) less likelyto initiate sexually activities early. Females in the central region (OR=1.51) and catholicmales (OR=1.63) were more likely to have more sexual partners.Encouraging these young people to be faithful to one uninfected partner, abstinence fromsexual activities, use condoms consistently and delay sexual initiation will help curb the spread of STIs in Malawi.

Abstract:

Sexually transmitted infections impose a huge burden on public health. The epidemic trajectories of such infections form part of a complex system of pathogen transmission, and are dependent on both pathogen characteristics and the structure and dynamics of the underlying sexual contact network. This thesis uses a dynamic network model which realistically represents human sexual contact dynamics in order to investigate the interactions be- tween these factors via three different approaches. Firstly, a transmission model is used to evaluate the role of pathogen du- ration of infectiousness in shaping the effective network over which an STI may spread. This allows us to examine the way in which the importance of different individual-level risk factors (such as number of sexual partners over five years) differs based on pathogen properties. Next, we expand this model to include evolution of a pathogen's genetic sequence, in order to study the extent to which population structure affects the structure of phylogenetic trees resulting from sampled sequences. Finally, we use this same transmission and evolution model to look at the skyline method of reconstructing past changes in effective population size, in order to estimate the number of sequence samples needed to be able to distinguish between a stable and a growing pathogen population and to ~ investigate the effect of network dynamics on the accuracy of this method.

Abstract:

The United States has the highest rates of teenage pregnancies, births, abortions, and sexually transmitted infections in the industrialized world. African American teen pregnancies and sexually transmitted infections are on the rise in many rural southwest school districts in the State of Georgia where the sex education curriculum is nonexistent or solely focuses on abstinence. Georgia ranked 4th in cases of primary and secondary syphilis, 6th in AIDS, 12th in gonorrhea, 14th in teen pregnancies, and 17th in chlamydia in the United States in 2012. The purpose of this qualitative study was to evaluate the perceptions of residents of a primarily African American rural southwest Georgia community regarding the importance of sex education and their knowledge of the school district's sex education curriculum. It specifically investigated abstinence-only sexual education using Bronfenbrenner's ecological learning theory. Study participants (n = 25) were African American youths in 9th grade, their parents, school officials, religious leaders, policymakers, and health advocates. The research questions were designed to investigate participants' knowledge of sexual health and effective sex education curricula for their school district. Data were collected from the participants via semi-structured interviews. MAXQDA 11.1 software was used for thematic analysis of transcribed interviews. The findings demonstrated community support for a comprehensive sex education curriculum and the need for a new paradigm in social policy that suggests initiatives should be evidence-based to achieve maximum efficacy in policy analysis. The study provides a baseline for school officials to assess community opinions regarding the acceptance of a comprehensive sex education curriculum.

Abstract:

Background: Sexually transmitted diseases (STD) remain a public health concern in worldwide. Human immunodeficiency virus (HIV), one of the STDs, is associated with the increase risk of other STD infections. According to Centers for Disease Control and Prevention (CDC), individuals who are infected with STDs are more likely to be infected with HIV than uninfected individuals. As HIV and other STDs share the same transmission route, the co-infection may be observed more frequently in the population. To control the number of co-infection, screening programs are essential in all areas. While screening for individual infections are necessary, the prevalence of co-infection should also be evaluated for surveillance programs. The prevalence of individual STDs have been studied in various reviews, but the population prevalence of the co-infection was not widely studied. Therefore, a systematic review is conducted to provide a summary of the prevalence of HIV with syphilis, chlamydia, gonorrhea and herpes simplex virus (HSV-2) and co-infection in various populations. Methods: PubMed database is chosen for selection of potential publications in this systematic review. Various keywords are used for the search and and only English publications are selected for review. Studies with statistical data on individual infection but not the co-infection were excluded. Results: Ten studies from various populations are selected for this review. Nine studies were conducted in healthcare facilities and one was conducted in a working site. The number of study participants ranged from 336 to 1661 with a mean age of 32 years old. The average of prevalence of HIV and the chosen STDs was around 20%—highest prevalence is observed in HSV-2 with HIV co-infection. Conclusion: The prevalence of co-infection is low but it cannot be neglected. Simultaneous screening for HIV and other STDs is not necessary in all areas, but it will be very useful in certain facilities where high-risk populations, for example sex workers, MSM etc are served. Such low prevalence of STD co-infection should be maintained and it is the responsibility of both the individuals and the society.
