Objectives To assess cognitive performance and psychomotor impairment in an HIV-positive cohort, well-suppressed on combination antiretroviral therapy (cART), in an Asian resource-limited setting. Methods Cross-sectional sociodemographic and cognitive data were collected in 329 HIV-positive and 510 HIV-negative participants. Cognitive performance was assessed using the International HIV Demen...

BACKGROUND Physical performance measures can predict incident disability, but little research has assessed and compared how these measures predict progressive and rapid-onset (catastrophic) disability. The authors evaluated the ability of upper and lower extremity performance measures to predict progressive and catastrophic disability in activities of daily living (ADL), mobility, and upper ext...

The present study analyzed the development of manual midline crossing in a sample of one hundred sixty 2- to 6-year-old children and considered test construction factors that could affect the test design. The test construction factors addressed were (a) the effect of biasing the hand used for object manipulation and (b) the effect of distance from midline required for task completion on the fre...

Horses with pituitary pars intermedia dysfunction (PPID) react to domperidone administration with an exaggerated increase in endogenous adrenocorticotropins (ACTH) concentrations. Specifically, a dose of 2.5 mg/kg domperidone orally resulted in an endogenous ACTH concentration in PPID horses that was 2.9 0.68 times baseline values at 4 h post-administration. Endogenous ACTH concentrations in ho...

1. A full literature review was completed. 2. A dynamic model of the system was completed and simulation results were used to design and construct the test rig. 3. A fully operational test rig (mini backhoe arm) has been installed and instrumented in the ABE Fluid Power laboratory at Purdue University. 4. Data has been collected on the test rig while operating the system in various modes. 5. Re...

The Boston Qualitative Scoring System (BQSS) was used as a method to examine executive skills on the Rey-Osterrieth complex figure (ROCF). Young-adult survivors of childhood brain tumor (N = 31) and a demographically-matched comparison group (N = 33) completed the ROCF copy version and Grooved Pegboard, and informants were administered the Scales of Independent Behavior-Revised (SIB-R) and Beha...
