The Materials Map is an open tool for improving networking and interdisciplinary exchange within materials research. It enables cross-database search for cooperation and network partners and discovering of the research landscape.

The dashboard provides detailed information about the selected scientist, e.g. publications. The dashboard can be filtered and shows the relationship to co-authors in different diagrams. In addition, a link is provided to find contact information.

Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>Men who have sex with men (MSM) are at greater risk for sexually transmitted infections (STIs). Data on MSM chlamydia and gonorrhea prevalence estimates and associated risk factors is scarce. To our knowledge, this is the first study to describe the prevalence and the determinants of both chlamydia and gonorrhea infections in MSM in Portugal.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>We conducted a cross-sectional study using data from 1,832 visits to CheckpointLX, a community-based center for screening blood-borne viruses and other STIs in MSM.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Overall prevalence of chlamydia or gonorrhea in our sample was 16.05%, with 14.23% coinfection and 40.73% asymptomatic presentation among those testing positive. Anorectal infection was most common for chlamydia (67.26%), followed by urethral (24.78%) and oral (19.47%) infection. Oral infection was most common for gonorrhea (55.63%), followed by anal (51.25%) and urethral (17.50%) infection. In multivariate analyses, young age (U = 94684, p = 0.014), being foreign-born (χ2=11.724, p = 0.003), reporting STI symptoms (χ2=5.316, p = 0.021), inhaled drug use (χ2=4.278, p = 0.039) and having a higher number of concurrent (χ2=18.769, p &amp;lt; 0.001) or total (χ2=5.988, p = 0.050) sexual partners were each associated with higher rates of chlamydia or gonorrhea infection.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Young and migrant MSM are a vulnerable population to STIs, as are those who use inhaled drugs and those with a higher number of concurrent or total sexual partners. Although Portugal has no guidelines on chlamydia and gonorrhea screening, our results point towards a need for greater awareness about the importance of high frequency screening for those at increased risk (i.e. every 3 to 6 months).</jats:p></jats:sec><jats:sec><jats:title>Key messages</jats:title><jats:p>Higher prevalence was found in young and migrant MSM, those with higher number of concurrent or total sexual partners, and those who use inhaled drugs. There is a need for greater awareness about the importance of high frequency STI screening for MSM at increased risk.</jats:p></jats:sec>
