Methamphetamine is a drug that is significantly abused worldwide, Although long-lasting depletion of dopamine and other dopamine nerve terminal markers has been reported in striatum of nonhuman primates receiving very high doses of the psychostimulant, no information is available for humans. We found reduced levels of three dopamine nerve terminal markers(More)
We measured levels of methamphetamine and those of its metabolite amphetamine in 15 autopsied brain regions of 14 human methamphetamine users. Only slight regional differences were observed in drug concentrations among the brain areas. Although, some redistribution of the drugs probably occurred postmortem, these data suggest that methamphetamine might not(More)
The purpose of this paper is to report prosthesis-related issues of importance that were identified by a diverse group of persons living with lower limb amputations (LLA) and prostheses. These perceptions and themes validate some old assumptions and challenge others, report both common and unusual experiences, and indirectly identify the information level(More)
Care of veterans and servicemembers with major traumatic limb loss from combat theaters is one of the highest priorities of the Department of Veteran Affairs. We achieved a 62% response rate in our Survey for Prosthetic Use from 298 Vietnam war veterans and 283 servicemembers/veterans from Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) who(More)
OBJECTIVE To describe diet and exercise practices from a nationally representative sample of U.S. adults with type 2 diabetes. METHODS We analyzed data from 1,480 adults older than 17 years with a self-reported diagnosis of type 2 diabetes in the Third National Health and Nutrition Examination Survey (NHANES III). Fruit and vegetable consumption was(More)
This study describes the sensations and pain reported by persons with unilateral lower extremity amputations. Participants (n = 92) were recruited from two hospitals to complete the Prosthesis Evaluation Questionnaire which included questions about amputation related sensations and pain. Using a visual analog scale, participants reported the frequency,(More)
Animal data have long suggested that an adaptive upregulation of nucleus accumbens dopamine D1 receptor function might underlie part of the dependency on drugs of abuse. We measured by quantitative immunoblotting protein levels of dopamine D1 and, for comparison, D2 receptors in brain of chronic users of methamphetamine, cocaine, and heroin. As compared(More)
Cognitive impairment has been reported in some chronic users of psychostimulants, raising the possibility that long-term drug exposure might damage brain neuronal systems, including the cholinergic system, which are responsible for normal cognition. We measured the activity of choline acetyltransferase (ChAT), the marker enzyme for cholinergic neurones, in(More)
OBJECTIVE To describe the incidence of falls, risk factors for falls, and the frequency of fall-related fractures in a cohort of individuals with diabetes and a prior foot ulcer. RESEARCH DESIGN AND METHODS A total of 400 individuals with diabetes and a prior foot ulcer were recruited from two western Washington State health care organizations and(More)
Prosthetic care is a vital aspect of healthcare and rehabilitation for veterans and servicemembers with major traumatic limb loss. Our survey queried 581 veterans and servicemembers with limb loss from the Vietnam and Operation Iraqi Freedom (OIF)/Operation Enduring Freedom (OEF) conflicts. Among survey participants, 78.2% from the Vietnam conflict and(More)
