Intentions to use different modalities of long-acting HIV PrEP among men who have sex with men and transgender and gender diverse persons in the Netherlands
Insight into intentions to use long-acting HIV pre-exposure prophylaxis (PrEP) is essential for successful implementation. We assessed intention to use three hypothetical long-acting PrEP modalities (oral, intramuscular and subdermal) among HIV-negative men who have sex with men (MSM) and transgender and gender diverse persons in Amsterdam, recruited through the Amsterdam Cohort Studies (ACS-participants) and social media (survey-participants). I…
Public health actions in response to pathogen detection in wastewater and the environment: A scoping review
Introduction Rapid detection of infectious disease agents is crucial for timely public health responses. Wastewater and environmental surveillance (WES) offers a complementary approach by detecting pathogens shed by infected individuals, including asymptomatic cases. This scoping review provides an overview of reported public health actions in response to WES for human pathogens. It also summarizes sampling and analysis methods and offers insight…
Opportunities for improved indicator-based HIV testing in the hospital setting: A structural equation model analysis
Indicator condition (IC)-guided HIV testing, i.e., testing when diagnosing a condition associated with HIV, is a feasible and cost-effective testing strategy to identify undiagnosed individuals. Assessing determinants for IC-guided testing may identify opportunities for improvement. A survey study based on the Theory of Planned Behaviour (TPB) was conducted among 163 hospital physicians from five specialties in Amsterdam, the Netherlands. Structu…
Pre-exposure prophylaxis (PrEP) use trajectories and incidence of HIV and other sexually transmitted infections among PrEP users in Belgium: A cohort analysis of insurance claims data from 2017 to 201…
The study highlights challenges in PrEP persistence and a high incidence of bacterial STIs among individuals receiving PrEP. Tailored prevention support is crucial for individuals with ongoing HIV risk to optimise PrEP effectiveness. Integrated STI testing and prevention interventions within PrEP care are necessary to mitigate STI acquisition and transmission among PrEP users
Patterns of PrEP and condom use among PrEP users in Belgium: A web-based longitudinal study
Our findings show that there is little variation in PrEP use over time and that PrEP use was associated with sexual behaviours, which could be taken into account when designing tailored PrEP care
HIV Pre-exposure Prophylaxis (PrEP) Care in Belgium: A mixed-methods Study on PrEP Users’ Experiences and Service Delivery Preferences
The Impact of Pre-exposure Prophylaxis on Sexual Well-Being Among Men Who Have Sex with Men
Linkage to HIV care before and after the introduction of provider-initiated testing and counselling in six Rwandan health facilities
HIV testing and counselling forms the gateway to the HIV care and treatment continuum. Therefore, the World Health Organization recommends provider-initiated testing and counselling (PITC) in countries with a generalized HIV epidemic. Few studies have investigated linkage-to-HIV-care among out-patients after PITC. Our objective was to study timely linkage-to-HIV-care in six Rwandan health facilities (HFs) before and after the introduction of PITC…
A longitudinal study on determinants of HPV vaccination uptake in parents/guardians from different ethnic backgrounds in Amsterdam, the Netherlands
Human papillomavirus (HPV) vaccination coverage in the Netherlands is low (~60%) compared to other childhood vaccinations (>90%), and even lower among ethnic minorities. The aim of this study was to explore the possible impact of ethnicity on the determinants of both HPV vaccination intention and HPV vaccination uptake among parents/guardians having a daughter that is invited for the HPV vaccination. In February 2014, parents/guardians living in …
HIV and hepatitis C treatment uptake among people who use drugs participating in the Amsterdam Cohort Studies, 1985–2015
Perceived HIV Status is a Key Determinant of Unprotected Anal Intercourse Within Partnerships of Men Who Have Sex With Men in Amsterdam
Increased seroprevalence of IgG-class antibodies against cytomegalovirus, parvovirus B19, and varicella-zoster virus in women working in child day care
This study confirms the clear association between employment in child day care centres and infection with CMV and B19V. Intervention policies, like screening of new employees and awareness campaigns emphasizing hygienic measures among DCW, should be implemented urgently to improve the maternal health of these women and the health of their offspring
Long-term voluntary counseling and testing (VCT) uptake dynamics in a multicountry HIV workplace program in sub-Saharan Africa
High uptake of HIV voluntary counseling and testing (VCT) services is important for the success of HIV workplace programs in sub-Saharan Africa. From 2001 onwards, Heineken, a multinational brewing company, implemented a comprehensive HIV prevention and treatment program for employees and their dependents of its African subsidiaries. Confidential in-house VCT is part of this program. VCT uptake dynamics over time, and factors associated with earl…
Low HIV testing rates among tuberculosis patients in Kampala, Uganda
The overall HIV test uptake was surprisingly low at 40%. The HIV test uptake was significantly higher among TB patients who were identified at hospital, among females and in the unemployed
