Sensitivity and specificity of Dried Blood Spot and Plasma Separation Card samples for Hepatitis C Virus RNA Testing
Dried blood spots (DBS) and plasma separation cards (PSC) have the potential to improve access to hepatitis C virus (HCV) testing. This multicenter study evaluated the performance of two HCV RNA assay platforms using capillary or venous DBS and PSC. Participants were enrolled in Cameroon, Rwanda, Georgia, and Greece. DBS and PSC prepared from capillary and venous blood samples were collected from three target populations; individuals at risk of H…
Population size estimation of people who inject drugs using capture-recapture analysis of multiple respondent-driven sampling rounds: Implications for HIV/HCV burden and harm reduction service plannin…
Based on this community-based population size estimate, the prevalence of injection was nearly double the official national Greek average. The annual distribution of syringes should increase by 5.6 times to reach the WHO target (≥200 syringes/PWID/year). These findings demonstrate how community-based programs with multiple RDS rounds can also yield population estimates essential for evidence-based drug policy interventions

Effects of Nutrition, and Physical Activity Habits and Perceptions on Body Mass Index (BMI) in Children Aged 12–15 Years: A Cross-Sectional Study Comparing Boys and Girls
Background : The aim of the present study was to examine the effects of socioeconomic status, nutrition and physical activity lifestyle habits and perceptions on Body Mass Index (BMI) in children aged 12-15 years in Greece. Furthermore, to compare the difference between the two sexes. Methods: This is a cross-sectional study conducted on a representative secondary school cohort that included 5144 subjects, aged 12 to 15 years. Students and their …
Sexual Mixing and HIV Transmission Potential Among Greek Men Who have Sex with Men: Results from Sophocles
HIV incidence among men who have sex with men (MSM) in Greece remains unchanged despite effective response to a recent outbreak among people who inject drugs (PWID). Network factors are increasingly understood to drive transmission in epidemics. The primary objective of the study was to characterize MSM in Greece, their sexual behaviors, and sexual network mixing patterns. We investigated the relationship between serostatus, sexual behaviors, and…
Pre-exposure Prophylaxis Persistence Among Greek Sexual Minority Men: Results from PrEP for Greece (P4G) Study
Food insecurity among people who inject drugs in Athens, Greece: A study in the context of Aristotle programme
Objective: To measure the prevalence of food insecurity and explore related characteristics and behaviours among people who inject drugs (PWID). Design: Cross-sectional analysis of a community-based programme for HIV infection among PWID (ARISTOTLE programme). Food insecurity was measured by the Household Food Insecurity Access Scale. Computer-assisted interviews and blood samples were also collected. Setting: A fixed location in Athens Metropoli…
The cost of a late-detected outbreak among people who inject drugs. A modeling study
Integrated molecular and affiliation network analysis: Core-periphery social clustering is associated with HIV transmission patterns
High-risk behaviors and their association with awareness of HIV status among participants of a large-scale prevention intervention in Athens, Greece
The prevalence of risky behaviors related to drug injection decreased in the context of Aristotle. Knowledge of HIV infection was associated with safer drug injection-related behaviors among PWID. This highlights the need for comprehensive interventions that scale-up HIV testing and help PWID become aware of their HIV status
Health and health needs of migrants in detention in Greece: Shedding light to an unknown reality
BACKGROUND: Population movements have been increasing over the past years in Europe due to socioeconomic factors, global turbulence and conflicts, especially in the area of Middle East. The presence of migrant populations in Europe challenges health systems due to increased requirements for health care provision. However, to date there is limited published data on the burden of disease among this population (in Greece and elsewhere). Our objectiv…
Identifying, linking, and treating people who inject drugs and were recently infected with HIV in the context of a network-based intervention
Identifying and linking people to care soon after HIV infection could limit viral transmission and protect their health. This work aims at describing the continuum of care among recently HIV-infected people who inject drugs (PWID) and participated in an intervention in the context of an HIV outbreak in Athens, Greece. The Transmission Reduction Intervention Project (TRIP) conducted risk network-based contact tracing and screened people for recent…

Homelessness and Other Risk Factors for HIV Infection in the Current Outbreak Among Injection Drug Users in Athens, Greece
Objectives. We examined HIV prevalence and risk factors among injection drug users (IDUs) in Athens, Greece, during an HIV outbreak. Methods. We used respondent-driven sampling (RDS) to recruit 1404 IDUs to the Aristotle intervention in August to October 2012. We interviewed participants and tested for HIV. We performed bivariate and multivariate analyses. Results. Estimated HIV prevalence was 19.8% (RDS-weighted prevalence = 14.8%). Odds of infe…
