A cost-effectiveness comparison of supported employment and rehabilitative day treatment

Recent research suggests that, for some people with severe mental illness, supported employment could improve vocational outcomes for little additional expense. This study describes the costs and client outcomes in one mental health center that converted two rehabilitative day treatment programs to supported employment. Converting from day treatment to supported employment improved vocational outcomes significantly without increasing costs. Although total costs for community treatment were lower in both sites after implementing supported employment, differences appeared to be due to decreasing unit costs over the study period. Results illustrate the importance of testing the effects of cost estimation methods on findings.This study was supported by West Central Services, the New Hampshire Division of Mental Health and Developmental Services, and NIMH grant K02-MH-00839.

Comparison of the blood-brain barrier and liver penetration of acridine antitumor drugs

Summary The blood-brain barrier penetration of amsacrine and its analogs 9-({2-methoxy-4-[(methylsulfonyl)-amino]phenyl}amino)-,5-dimethyl-4-acridine carboxamide (CI-921) and M-[2-(dimethylamino)ethyl]-acridine-4-carboxamide (AC) was measured in the barbiturate-anesthetized mouse. After intracarotid administration, AC was almost completery extracted (90%) in a single transit through the brain capillaries, whereas CI-921 (20%) and amsacrine (15%) were moderately extracted. AC is retained in the brain; no loss of AC from the brain was apparent at 1, 2, 4, or 8 min after injection. In contrast, after intraportal administration, 75% of the AC, 94% of the CI-921, and 57% of the amsacrine was extracted in a single transit through the hepatic vasculature. Rather than being retained in the mouse liver, these acridine antitumor agents show time-dependent loss (t _1/2=10 min for amsacrine and AC, 24 min for CI-921). We conclude that unlike most antitumor agents, these acridine drugs appear to penetrate the blood-brain barrier readily.This study was supported by the Auckland Medical Research Foundation (New Zealand), by the Medical Research Foundation (New Zealand), by the National Science Foundation (United States/New Zealand Cooperative Science Program), by the United States Veterans Administration, and by NIH grant NS 25554     

Lipoid Proteinosis: Case Report

A 20-month-old Kuwaiti girl had manifestations of lipoid proteinosis, a rare autosomal recessive disorder seen more commonly in Caucasians. This condition is diagnosed based on clinical, histopathologic, and ultrastructural criteria. Its biochemical and genetic aspects are still poorly understood.     

Personal history,training, and worksite as predictors of back pain of nurses

Back pain among nurses is a common problem. Prior studies of this problem have been based on cross-sectional or retrospective data. This 18-month prospective study involving nurses newly graduated from nursing school investigated personal, worksite, and training factors associated with future risk of back pain. Each nurse underwent a preliminary interview and periodic follow-ups to identify those with back injuries. Contingency tables and logistic regression analyses demonstrated that prior significant back pain episodes (evidenced by previous job changes because of back pain, frequent medication use, etc.) were associated with increased future risk. Training at nursing school or on the job did not have a protective effect. This pilot study therefore suggests factors useful in placement and counseling of new nurses and indicates the need for further implementation of mechanical lift assist device use. © 1994 Wiley-Liss, Inc.     

Genetic polymorphisms in dopamine-related genes and smoking cessation in women: a prospective cohort study

Background  

Genes involved in dopaminergic neurotransmission have been suggested as candidates for involvement in smoking behavior. We hypothesized that alleles associated with reduced dopaminergic neurotransmission would be more common in continuing smokers than among women who quit smoking.     

The Nurse Practitioner's Role

Decisional incapacity is the inability to make decisions for oneself caused by mental or physical impairment. With technologic advances in health care and the growing proportion of elderly in American society, the problem of decisional incapacity occurs more frequently. In the past, medical decision making was based on the principle of beneficence, and the judgment of others was used to determine medical interventions. The current trend is to base decisions as much as possible on the principle of patient autonomy. Advance directives allow for the greater use of this principle.
The primary care nurse practitioner (NP) can take an active role in promoting patient autonomy by helping the adult patient plan for decisional incapacity. By including the value history as a routine part of the health history, the NP can help patients identify their beliefs, values, and attitudes about health care. This documented value history can then be used to provide evidence of a patient's wishes should he or she become decisionally incapacitated.     

An effective treatment for functional urinary incoordination

Twenty women diagnosed with functional urinary incoordination were randomly assigned to one of two treatment groups: biofeedback or progressive muscle relaxation. Ten subjects who were placed on a waiting list prior to treatment allocation served as a comparison group. The biofeedback intervention focused specifically on retraining of pelvic floor musculature (PFM). Patients were assessed pretreatment, posttreatment, and at 2-month follow-up. Outcome measures included self-reported symptomatology, psychological functioning, psychophysiological assessment of the PFM, and urologist ratings of problem severity and treatment efficacy. Both treatment approaches proved effective in improving symptomatology and psychological state. Subjects on the waiting list demonstrated no change in urological difficulties. No differences were found between the two treatment groups on any of the outcome measures. Theoretical and practical implications of the results are discussed.
