Risk factors for HIV and STI diagnosis in a community-based HIV/STI testing and counselling site for men having sex with men (MSM) in a large German city in 2011-2012.

Background: In recent years community-based voluntary counselling and testing sites (CB-VCT) for men having sex with men (MSM) have been established in larger cities in Germany to offer more opportunities for HIV testing. Increasingly, CB-VCTs also offer testing for other bacterial sexually transmitted infections. In Hamburg, tests in CB-VCTs are offered free and anonymously.

Neural correlates of temporal context discrimination.

This study investigated event-related potential (ERP) effects when judgments about temporal context (recency judgments) required the retrieval of different amount of information. Subjects studied two consecutively presented word lists and at test made recency judgments to word pairs composed of two previously studied words, one drawn from each list ('Old + Old different' pairs), both drawn from the same list ('Old + Old same' pairs), or two unstudied words ('New + New' pairs). A frontopolar old/new effect was elicited by correct recency judgments which did not differ between both 'Old + Old' pairs.
