BACKGROUND Sexual networks may place U.S. Black men who have sex with men (MSM) at increased HIV risk. METHODS Self-reported egocentric sexual network data from the prior six months were collected from 1,349 community-recruited Black MSM in HPTN 061, a multi-component HIV prevention intervention feasibility study. Sexual network composition, size, and density (extent to which members are havi...
Automatic and attentional components of semantic priming and the relation of each to episodic memory were evaluated in young and older adults. Category names served as prime words, and the relatedness of the prime to a subsequent lexical decision target was varied orthogonally with whether the target category was expected or unexpected. At a prime-target stimulus-onset asynchrony (SOA) of 410 m...
The perception and production of the mid-front Finnish vowels /i/, /e/, /y/, and /ø/ were investigated in fourteen Finnish-speaking subjects. In the perception experiment, synthesized long vowels were used as stimuli in order to identify category prototypes. For production, the subjects were asked to pronounce words including these vowels as short and long variants. This study introduces a new ...
BACKGROUND To compare the Centers for Disease Control and Prevention (CDC) paediatric classification system with the long-term course of perinatal human immunodeficiency virus type 1 (HIV-1) infection. METHODS Prospective study on 366 perinatally infected children followed-up from birth and checked at least every 2 months. Survival, smoothed hazard, adjusted hazard ratio of death, and transit...
PURPOSE To identify size criteria for complex cystic renal masses that can distinguish renal cell carcinoma from benign cysts supplementing the Bosniak classification. MATERIALS AND METHODS We reviewed the records of 97 patients who underwent surgery for complex cystic renal masses from January 2001 to April 2010. The pathological results were compared with the lesion sizes measured by preope...
BACKGROUND AND PURPOSE Pathologic studies suggest that neovascularization and hemorrhage are important features of plaque vulnerability for disruption. Our aim was to determine the associations of these features in carotid plaques with previous cerebrovascular ischemic events by using high-resolution CE-MRI. MATERIALS AND METHODS Forty-seven patients (36 men; mean age 72.5 ± 10 years) underwe...
IMPORTANCE Clinical observations suggest that patients with age-related macular degeneration (AMD) have vision problems, particularly in dim light conditions. Previous studies on structural-functional analysis in patients with AMD with reticular drusen (RDR) have focused on photopic sensitivity testing but have not specifically assessed scotopic function. OBJECTIVE To evaluate retinal functio...
