City-level drug policies in Portugal: the Covid-19 pandemic as an analyzer of h...

Background: The COVID-19 pandemic health crisis and its potential implications for people who use drugs (PWUD) created permissive conditions toward social innovation and experimentation. Still, it also exposed gaps in harm reduction approaches. Harm reduction responsiveness was informed by the priorities defined at the local level, so it was not applied uniformly in different regions. This paper intends to cont...

Preference towards HIV Self-Testing above Other Testing Options in a Sample of ...

We analyzed men who have sex with men (MSM) from Denmark, Germany, Greece, Portugal and Spain to identify who would choose HIV self-testing as their preferred testing method and assessed their preferred setting to acquire a self-testing kit and to confirm a reactive result. In 2016, we recruited an online sample of 3725 HIV-negative MSM. We used Poisson regression to identify factors associated with choosing se...

Sexual behaviour patterns and STI risk: results of a cluster analysis among men...

Objectives Portugal has the highest HIV incidence rate in Western Europe. The proportion assigned to sexual contact between men recently increased to more than 30% of all HIV infections. Men who have sex with men (MSM) are vulnerable to the acquisition of other sexually transmitted infections (STIs), increasing the per-contact risk of HIV infection. Building on syndemic theory, the aim of this analysis was to i...

Lisbon’s COVID 19 response: harm reduction interventions for people who use alc...

Four emergency shelters were instituted in Lisbon during COVID-19, and are still in operation. Between March and August 2020, they served over 600 people. The shelters host a diverse population, including people experiencing homelessness, foreigners, LGBTI + people, those with reduced mobility, couples, those with pets, and People Who Use Drugs, including alcohol (henceforth PWUD). Individuals are provided care...

Potential of HIV Self-Sampling to Increase Testing Frequency Among Gay, Bisexua...

Background: Late HIV diagnosis remains frequent among the gay, bisexual, and other men who have sex with men (GBMSM) population across Europe. HIV self-sampling could help remove barriers and facilitate access to testing for this high-risk population. Objective: We assessed the capacity of HIV self-sampling to increase the testing frequency among GBMSM living in Denmark, Germany, Greece, Portugal, Romania, and ...

Association of Sexualized Drug Use Patterns with HIV/STI Transmission Risk in a...

We estimated the prevalence of overall sexualized drug use (SDU) and of chemsex in particular, assessed patterns of drug use, and identified subpopulations of men who have sex with men (MSM) where SDU and chemsex are more frequent. Using data from an online survey of 9407 MSM recruited during 2016 in 7 European countries, we calculated the proportion of participants who reported SDU and chemsex (mephedrone, met...

Knowledge, actual and potential use of HIV self‐sampling testing kits among MSM...

Aim To describe the knowledge as well as current and potential use of self-sampling kits among men who have sex with men (MSM) and to analyse their preferred biological sample and result communication method. Methods We analyse data of MSM of HIV negative or unknown serostatus from an online survey conducted in eight countries (Belgium, Denmark, Germany, Greece, Portugal, Romania, Slovenia and Spain) between Ap...

Urgent need for demonstration projects in Portugal to produce pre-exposure prop...

COBA-Cohort: a prospective cohort of HIV-negative men who have sex with men, at...

Introduction Community-based voluntary counselling and testing (CBVCT) services for men who have sex with men (MSM) can reach those most-at-risk and provide an environment for gay men that is likely to be non-stigmatising. Longitudinal data on the behaviour of HIV-negative MSM are scarce in Europe. The aim of this protocol, developed during the Euro HIV Early Diagnosis And Treatment (EDAT) project, is to implem...

Incident risk factors as predictors of HIV seroconversion in the Lisbon cohort ...

HIV incidence in men who have sex with men (MSM) is increasing in western countries, including Portugal. We aimed to estimate HIV incidence and to assess how individual short-term changes in exposures over time predict seroconversion. We evaluated participants of an open cohort of HIV-negative MSM enrolled after testing at a community-based voluntary HIV counselling and testing centre in Lisbon. At each evaluat...
