Determinants and prediction of Chlamydia trachomatis re-testing and re-infection within 1 year among heterosexuals with chlamydia attending a sexual health clinic
Background: (chlamydia) is one of the most common sexually transmitted infections (STI) globally, and re-infections are common. Current Australian guidelines recommend re-testing for chlamydia 3 months after treatment to identify possible re-infection. Patient-delivered partner therapy (PDPT) has been proposed to control chlamydia re-infection among heterosexuals. We aimed to identify determinants and the prediction of chlamydia re-testing and re…
The duration and body position during tongue-kissing among heterosexual men and women
Background Emerging data suggest tongue-kissing may transmit gonorrhea. We aim to examine the duration or body position of heterosexual men and women during tongue-kissing (henceforth, known as kissing). Methods A cross-sectional survey among heterosexual men and women attending the Melbourne Sexual Health Centre in Australia between May 2019 and March 2020 collected data on the duration and body position (i.e., on top of or lying down underneath…
Repeat infections with chlamydia in women may be more transcriptionally active with lower responses from some immune genes
Chlamydia trachomatis , the most common bacterial sexually transmitted infection worldwide, is responsible for considerable health burden due to its significant sequelae. There are growing concerns about chlamydial treatment and management due to widely documented increasing burden of repeat infections. In the current study, a cohort study design of 305 women with urogenital chlamydial infections demonstrated that 11.8% of women experienced repea…
Sexual Activities and Changes in Condom Use in Group Sex Events Among Female Sex Workers in Melbourne, Australia
Background: There are few studies investigating group sex among female sex workers (FSWs). This study aimed to examine the typical number of group sex participants, sexual activities and condom use in group sex among FSWs attending a sexual health clinic in Melbourne, Australia. Methods: We conducted a cross-sectional survey between May 1, 2019 and March 13, 2020 among FSWs in Melbourne. Participants were asked whether they had participated in gr…
Improving Access to Sexual Health Services in General Practice Using a Hub-and-Spoke Model
Improving access to sexual health services is critical in light of rising sexually transmitted infections (STIs). We evaluated a hub-and-spoke model for improving access to sexual health services in three general practices in Victoria, Australia. The primary outcome was the impact on HIV and STI (chlamydia, gonorrhoea, syphilis) testing. Segmented linear regression analysis was conducted to examine the trends in the total HIV/STI tests pre- (from…
Patterns of Sexual Practices, Sexually Transmitted Infections and Other Genital Infections in Women Who Have Sex with Women Only (WSWO), Women Who Have Sex with Men Only (WSMO) and Women Who Have Sex …
Despite rises in sexually transmitted infection (STI) notifications among Australian women in the last decade, limited STI surveillance data exist specifically for women who have sex with women. This study aimed to compare differences in sexual practices and positivity for STIs and other genital infections among women who have sex with men only (WSMO), women who have sex with women only (WSWO), and women who have sex with men and women (WSMW), an…
Human Papillomavirus Vaccine Course Completion Among Gay and Bisexual Men Who Have Sex With Men From a Time-Limited HPV Vaccination Catch-Up Program in Victoria, Australia
Background: To examine completion of the human papillomavirus (HPV) vaccination 3-dose regimen and factors associated with completion among men who have sex with men (MSM) aged ≤ 26 years participating in a time-limited HPV catch-up vaccination program in Victoria, Australia. Methods: MSM who received their first dose of HPV vaccine at Melbourne Sexual Health Centre in 2017 were followed until October 2019. Vaccination completion was defined as t…
Oral, Vaginal and Anal Sexual Practices among Heterosexual Males and Females Attending a Sexual Health Clinic
Sex practices among heterosexuals are not well studied. We aimed to explore sexual practices among heterosexuals attending a sexual health clinic. This cross-sectional survey was conducted at Melbourne Sexual Health Centre between March and April 2019. Data were collected on kissing, oral sex (fellatio or cunnilingus), vaginal sex, anal sex and rimming in the previous 3 months. Univariable and multivariable logistic regression analyses were perfo…
Sustaining success
HIVST increases the frequency of HIV testing among gay and bisexual men due, in part, to the practical, psychological, and social benefits it offers. To capitalize fully on these benefits, however, strategies to ensure the availability of highly reliable HIVST are required to sustain benefits beyond the confines of a structured research study
Understanding the Targeting and Uptake of HIV Testing Among Gay and Bisexual Men Attending Sexual Health Clinics
Why are we not screening for anal cancer routinely - HIV physicians’ perspectives on anal cancer and its screening in HIV-positive men who have sex with men
HIV physicians remain ambivalent regarding the most effective means to screen for anal cancer. More research is needed to address the physicians' concerns before anal cancer screening can be implemented into routine HIV care
High prevalence of rectal gonorrhoea among men reporting contact with men with gonorrhoea
The high proportion of positive cases of gonorrhoea among contacts in this study supports epidemiological treatment of MSM presenting as contacts of gonorrhoea
Exploring anal self-examination as a means of screening for anal cancer in HIV positive men who have sex with men
ASE may be an acceptable means for anal cancer detection in HIV-positive MSM but training in detecting abnormalities is needed. The preference for health professional examination and inadequate physical flexibility may preclude its use for some men. Future trials to confirm its wider acceptability will be needed before undertaking an effectiveness trial for detecting anal cancer
Women's experiences of pelvic inflammatory disease
This study explored the health-care experiences of women diagnosed with pelvic inflammatory disease. Semi-structured interviews were conducted with 23 women diagnosed with pelvic inflammatory disease. Many women felt empowered about their health post-diagnosis; however, a smaller number reported becoming hyper-vigilant towards symptoms. Infertility was the greatest concern for women. Inadequate information and treatment resulted in negative healt…
Gay and Bisexual Men’s Views on Rapid Self-Testing for HIV
Maximising retention in a longitudinal study of genital Chlamydia trachomatis among young women in Australia
The methods used were considered effective for recruiting and retaining women in the study. Further research is needed to improve participation from less well-educated women
Young pregnant women's views on the acceptability of screening for chlamydia as part of routine antenatal care
Chlamydia screening as part of routine antenatal care was considered highly acceptable among young pregnant women who recognized the benefits of screening and strongly supported its implementation as part of routine antenatal care. The acceptability of screening is important to the uptake of chlamydia screening in future antenatal screening strategies
Incentive payments to general practitioners aimed at increasing opportunistic testing of young women for chlamydia
