The goal of this clinical trial is to compare the effectiveness of doxycycline taken for on-demand pre-exposure prophylaxis (DoxyODPrEP) and its post-exposure use (DoxyPEP) in preventing bacterial sexually transmitted infections (STI), including chlamydia, gonorrhoea, and syphilis among men who have sex with men (MSM). The main questions it aims to answer are: 1. Is DoxyODPrEP superior to DoxyPEP? 2. Are both regimens safe? 3. Does the MSM community accept the use of doxycycline to prevent bacterial STI? Participants will be asked to take doxycycline according to the study arm they are randomly assigned to, and attend regular clinical follow-ups during the 2-year observation period. Researchers will compare the bacterial STI incidences between the two groups to see if DoxyODPrEP is superior to DoxyPEP.
This randomized controlled superiority study will be conducted during 2023-2025. The eligible participants are adult people living with HIV (PLWH) who are newly diagnosed with early syphilis. Participants will be randomized in a 1:1 ratio to receive single-dose benzathine penicillin G (BPG) (2.4 MU intramuscularly once) plus doxycycline (100 mg orally twice daily for 7 days) or single-dose BPG. The primary outcome is serologic response, defined as a decline of rapid plasma reagin (RPR) titer by 4-fold or greater, at week 24 and week 48; and the secondary outcomes include microbiologic response of syphilis and bacterial sexually transmitted infections (STIs) assessed by nucleic-acid amplification test (NAAT) at week 4.
Elimination of mother-to-child-transmission (EMTCT) of HIV, syphilis and hepatitis B are key priorities in Indonesia, the fourth most populous country in the world. Despite national guidelines and strong antenatal care attendance, coverage of antenatal screening for these diseases among pregnant women remains extremely limited in Indonesia. The Indonesian government is committed to improving the integration of HIV/syphilis/hepatitis B testing and treatment into the antenatal platform but currently lacks comprehensive evidence on interventions to support this. We will evaluate a low-cost and locally driven intervention based on the principles of continuous quality improvement to strengthen antenatal care and promote screening for HIV, syphilis and hepatitis B. Continuous Quality Improvement (CQI), which involves local antenatal care (ANC) teams systematically collecting and reflecting on local data to inform the design and implementation of service delivery, has been effectively used to strengthen ANC in a number of Sub-Saharan African countries but yet to be comprehensively evaluated in ANC services in Indonesia. This approach holds considerable promise for Indonesia, a highly populous and diverse country where a 'one size fits all' approach to the delivery of quality ANC rarely applies.
The TRI-MOM program aims to implement and evaluate a simplified (based on inexpensive rapid diagnostic tests), integrated (in governmental health facilities) and coordinated (between health care workers) strategy for the triple elimination of HIV, syphilis and HBV mother-to-child transmission (MTCT) in nine maternal and child health services, 5 in Burkina Faso and 4 in The Gambia. The TRI-MOM program has two components: 1. an "intervention" component consisting of a pilot study to reinforce the antenatal screening and prevention of MTCT (PMTCT) capacities for the 3 targeted infections through the implementation of a simplified, integrated and coordinated strategy of triple elimination of MTCT. 2. an "evaluation" component which will assess the impact of the TRI-MOM strategy on PMTCT services, reduction of HBV MTCT and women empowerment.
Project FEDE-ITS will improve the STI knowledge and its treatment, of adolescents in the 1st and 2nd year of compulsory secondary education in the intervention group compared to compared to the control group, and will modify the sexual risk practices and the perception of risky practices of alcohol and other drug use during sex of participants in the intervention group compared to the control group.

The SIM study is a single-centre, randomized, controlled trial with a 12-month follow-up period. The aim is to determine which of the 3 methods of follow-up is the most effective in promoting patient treatment compliance. The recruitment of participants will be done by invitation, and tests will be performed in a mobile unit in locations accessible to large populations. The goal is to perform 10,000 quick tests, with results confirmed by venereal disease research laboratory (VDRL) tests. Patients with a confirmed diagnosis according to VDRL test results will be randomized in one of three monitoring arms: follow-up by telephone, follow-up via a game in a smartphone app, or conventional follow-up by a health professional. All analyses will follow the intention-to-treat principle.
2.1 Primary Study Hypothesis In sub-Saharan Africa, between 2.5-17% of pregnant women are infected with syphilis [1]. It is estimated that 53-82% of women with untreated syphilis had adverse outcomes compared to only 10-21% of uninfected women[2]. The investigators and others have shown that syphilis screening integrated into an HIV antenatal clinic with prevention of mother to child transmission (PMTCT) is highly accepted with excellent uptake. Unfortunately, the minority of male partners come in for testing and treatment (1%-27%) which has important implications for the roll-out of rapid syphilis testing and the inability to detect reinfection with treponemal antibody test as the test will remain positive despite treatment. The investigators hypothesize that sending an SMS reminder or a telephone call reminder by a health care worker will be more effective than a standard notification slip given to women to bring male partners to antennal clinic for testing and treatment.
This is a observational study aims to assess anal and genital human papillomavirus (HPV) infection status among men who have sex with men (MSM) in China, and their knowledge and attitude about HPV vaccine.
