Semantic memory navigation in HIV: Conceptual associations and word selection patterns.

This proof-of-concept study aimed to characterize semantic memory profiles in individuals with human immunodeficiency virus (HIV) and mild neurocognitive impairment. Using a semantic relatedness task, we explored conceptual association and word selection patterns in people living with HIV (PLWH;  = 50) relative to people living without HIV ( = 46). We also studied whether word selection patterns in the PLWH group were associated with working memory capacity, cognitive flexibility and inhibitory control.

What Drives Task Performance in Fluency Tasks in People With HIV?

Fluency tasks require language (i.e., semantics, phonological output lexicon, and phonological assembly) and executive functions (i.

[Primary lung Kaposi sarcoma associated to AIDS in a heterosexual drug addict man].

A case of lung Kaposi sarcoma (KS) in the absence of cutaneomucosal lesions was observed in a 30-year-old heterosexual male with AIDS and a history of intravenous drug addiction. Both chest X-ray and CT scanning disclosed a diffuse nodular pattern in lungs, whereas endoscopy failed to demonstrate endobronchial damage. Cytological examination of the sample taken by transthoracic lung puncture proved compatible with primary KS, a rare neoplasia in heterosexual male drug addicts with AIDS.
