Results There were no behavioral differences between groups. OSU showed attenuated activation across risky and safe decisions in prefrontal cortex, insula, and dorsal striatum, exhibited lower anterior cingulate cortex (ACC) and dorsal striatum activation for risky decisions and greater inferior frontal gyrus activation for safe decisions. Those OSU with relatively more stimulant use showed greater dorsal ACC and posterior insula attenuation. In comparison, greater lifetime marijuana

use was associated with less neural differentiation between risky and safe decisions. OSU who chose more safe responses after losses exhibited similarities with CS relative to those preferring risky options. Discussion Individuals at risk for the development of stimulant use disorders presented less differentiated neural processing of selleck chemicals AZD9291 manufacturer risky and safe options. Specifically, OSU show attenuated brain response in regions critical for performance monitoring, reward processing and interoceptive awareness. Marijuana had additive effects by diminishing neural risk differentiation.”
“Background: The objectives of the study were to assess feasibility, continuation rates and patient satisfaction with self-administration of subcutaneous depot medroxyprogesterone acetate

(DMPA-SC).\n\nMaterials this website and Methods: The study included 50 DMPA-seeking women between the ages of 18 and 49 years enrolled at two Florida Planned Parenthood health centers. Participants were taught self-injection during their initial

study visit and, upon proficiency, self-injected one dose in clinic. Participants then injected a series of three more doses outside the health center over 9 months. Continuation rates, feasibility and acceptability were determined by analysis of four postinjection surveys.\n\nResults: Continuation of DMPA-SC at injection 4 was 74% (95% confidence interval 62%-86%). Overall, survey responses from the three at-home injections indicated the method to be convenient (95%), easy (87%) and recommendable to others (94%). Twenty percent of injections were met with difficulty, most commonly cited as plunger resistance. No pregnancies occurred in study.\n\nConclusions: Continuation was high with DMPA-SC self-injection. Participants reported injection to be easy and convenient and are likely to recommend self-administration to other women. Device issues are one potential deterrent. (C) 2012 Elsevier Inc.
