Teenage childbearing and welfare: preventive and ameliorative strategies.

The results of seven computer simulations suggest that strategies to prevent teenage childbearing may be more effective in reducing the number of young women who require welfare assistance than are strategies to improve the circumstances of teenagers who have already given birth. The first simulation constitutes a baseline projection, in which current levels and patterns of adolescent childbearing are assumed to continue to 1990. Three "preventive" simulations assume that no births or fewer births occur among teenagers during the projection period; and three "ameliorative" simulations assume that changes occur in the completed family size, marriage rate and educational attainment of teenage childbearers. Compared with the baseline projection, the three preventive strategies are estimated to reduce by 22-48 percent the number of adolescent childbearers who, as 20-24-year-olds in 1990, will be receiving welfare payments; the three ameliorative strategies cause only a 6-12 percent drop. The strategy with the least impact is the education scenario, in which adolescent mothers are assumed to be no more likely to drop out of school than are other comparable teenagers. The primary reason for the surprisingly small effect appears to be the relatively low earnings of women--even when they are high school graduates. All of the experimental scenarios tested, however, bring about at least some reduction in projected government spending for the three major public assistance programs considered (Aid to Families with Dependent Children, Medicaid and Food Stamps).

Long-term effects of linoleic-acid-enriched diet on albuminuria and lipid levels in type 1 (insulin-dependent) diabetic patients with elevated urinary albumin excretion.

We conducted a 2-year prospective randomised study to investigate the effects of a linoleic-acid-enriched diet on albuminuria and lipid levels in Type 1 (insulin-dependent) diabetic patients with elevated urinary albumin excretion (overnight urinary albumin excretion rate between 10 and 200 micrograms/min). Thirty-eight patients were randomly assigned to increase dietary polyunsaturated:saturated fatty acids ratio to 1.0 by replacement of saturated fat with linoleic-acid-rich products (n = 18, two dropouts, analysis was performed in n = 16) or to continue their usual diet (n = 20). The total fat and protein content of the diet was unaltered. Clinical characteristics, albuminuria, blood pressure, glomerular filtration rate, metabolic control and dietary composition were similar in the two groups at baseline. In the high linoleic acid diet group, linoleic intake rose from 7 +/- 4 to 11 +/- 2 energy % and polyunsaturated:saturated fatty acids ratio rose from 0.60 +/- 0.28 to 0.96 +/- 0.16 (p less than 0.001 compared to usual diet group). The median increase albuminuria was 58% (95% confidence interval, 13 to 109) during the first year (p less than 0.02) and 55% (95% confidence interval, 11 to 127) (p less than 0.01) during the second year. Glomerular filtration rate remained unaltered and filtration fraction tended to rise (p less than 0.05 compared to usual diet group). In the usual diet group, albuminuria did not significantly increased by 16% (95% confidence interval, -17 to 38) and glomerular filtration rate declined during the second year. Blood pressure tended to rise similarly in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Characteristics and treatment of homeless, mentally ill, chemical-abusing men.

Comparing two types of treatment modalities in treating homeless, mentally ill, chemical-abusing (HMICAs) men and studying their characteristics, 723 HMICAs were interviewed on their childhood and family background and their psychiatric and substance abuse disorders, and then randomly assigned into either therapeutic community (TC) or community residence (CR) programs. The TC and CRs were found to differ from one another in their intake and admission procedures, their preadmission and postadmission dropout rates, and the effects of treatment on psychological status. The TC admitted their clients into treatment faster, tended to take more impaired clients, and had a lower preadmission dropout rate than the CRs did. The CRs had a lower postadmission dropout rate and were able to retain clients longer than the TC did. Comparing clients who stayed in treatment one year or longer, the TC appears to be more effective than the CRs in reducing depressive, psychotic, and functional symptoms. HMICAs' childhood and family background reveal severe parental deprivations and high prevalence of alcohol and other drug abuse, mental illness, and criminal behavior among the clients' parents. HMICAs' characteristics suggest that these men are completely outside mainstream society. They are severely impaired psychiatrically, chronically addicted, and often involved with the criminal system, thus occupying multiple deviant roles.

Lowering HIV risk among ethnic minority drug users: comparing culturally targeted intervention to a standard intervention.

To test the efficacy of culturally targeted acquired immunodeficiency syndrome (AIDS) prevention programs on ethnic minority street drug users, 669 African-American and Puerto Rican drug users were assigned to receive either the National Institute on Drug Abuse (NIDA) standard intervention or a culturally competent enhanced intervention in a quasi-experimental study. The standard intervention was a two-session educational program, while both the African-American and Puerto Rican enhanced interventions provided additional AIDS information in a culturally appropriate fashion. Although human immunodeficiency virus (HIV) risk behaviors, as measured by Bell's risk indices, decreased, there were no meaningful significant differences between interventions. However, participants who went into drug treatment programs showed greater reduction in HIV risk behavior. Cultural interventions may provide better outcome if they concentrate on getting participants into drug treatment.

High- and low-structure treatments for substance dependence: role of learned helplessness.

We studied whether pretreatment levels of learned helplessness (LH) were related to outcomes for substance-dependent individuals receiving high-structure, behaviorally oriented (HSB) or low-structure, facilitative (LSF) treatment. The subjects were 120 substance-dependent patients randomly assigned to the HSB or the LSF treatment style for up to 12 weeks of weekly individual counseling. The two groups were compared across pretreatment characteristics as well as in-treatment, end-of- treatment, and 9-month postadmission follow-up outcome measures. Outcomes reflected reduction in problem severity, abstinence, retention, dropout rate, and ratings of treatment benefit. Significant and comparable reductions in symptoms occurred for the HSB and LSF patients both during treatment and at follow-up. Comparisons of other outcomes also did not consistently favor either treatment style. However, significant and consistent interactions were observed between LH and treatment styles with respect to several outcome measures, and these effects were independent of pretreatment levels of depression, addiction severity, and readiness for treatment. Specifically, the more "helpless" patients did significantly better in HSB treatment, whereas the less "helpless" patients had better outcomes in LSF treatment. A matching approach that assigns patients to high- and low-structure treatments based on pretreatment levels of LH might improve treatment outcomes for substance-dependent patients.

Treatment of depression--newer pharmacotherapies.

OBJECTIVES: Depressive disorders are persistent, recurring illnesses that impose enormous personal suffering on individuals and their families. Major depression alone is estimated as the fourth most important cause of worldwide loss in disability-adjusted life years and is likely to become the second most important within 20 years. A continued quest for more effective treatments has spawned newer antidepressants and herbal treatments, which have contributed to explosive growth in antidepressant prescribing, increasing pharmacy costs, and wider but sometimes confusing choices for clinicians and patients. This evidence report provides a comprehensive evaluation of the benefits and adverse effects of newer pharmacotherapies and herbal treatments for depressive disorders in adults and children. SEARCH STRATEGY: Pertinent literature from 1980 to January 1998 was identified from a specialized registry of controlled trials, meta-analyses, and experts. The registry contained trials addressing depression that had been identified from multiple electronic bibliographic databases, hand searches of journals, and pharmaceutical companies. The search, which yielded 1,277 records, combined terms "depression," "depressive disorder," or "dysthymic disorder" with a list of 32 specific "newer" antidepressant and herbal treatments. SELECTION CRITERIA: Randomized controlled trials were reviewed if they (1) were at least 6 weeks in duration; (2) compared a "newer" antidepressant with another antidepressant (newer or older), placebo, or psychosocial intervention; (3) involved participants with depressive disorders; and (4) had a clinical outcome. Two or more independent reviewers identified 315 trials that met these criteria. DATA COLLECTION AND ANALYSIS: Two persons independently abstracted data from each trial. Data were synthesized descriptively, paying attention to participant and diagnostic descriptors, intervention characteristics, study designs and clinical outcomes. Some data were analyzed quantitatively using an empirical Bayes random-effects estimator method. Primary outcomes were response rate, total discontinuation rates (dropouts), and discontinuation rates due to adverse events. Response rates were defined as a 50 percent or greater improvement in symptoms as assessed by a depression symptoms rating scale or a rating of much or very much improved as assessed by a global assessment method. MAIN RESULTS: There were 264 trials that evaluated antidepressants in patients (adults and children) with major depression. Of these, 81 compared newer agents with placebo, 150 newer with older agents, 32 newer agents with newer agents, and 1 newer agent with psychotherapy. There were 14 trials evaluating hypericum (St. John's wort), 27 trials each in primary care patients and older adults, 10 trials limited to patients with specific concomitant illnesses, 9 trials in patients with dysthymia, 3 trials each in patients with mixed anxiety depression and subsyndromal depression, 2 trials in adolescents, and 1 in the postpartum setting. Most trials were conducted in outpatients and examined only acute phase treatment of less than 12 weeks' duration. Newer antidepressants were more effective than placebo in treating major depression (risk ratio 1.6, 95% CI 1.5 to 1.7) and dysthymia (risk ratio 1.7, 95% CI 1.3 to 2.3). They were effective among older adults and in primary care patients. In general, there were no significant differences in efficacy among individual newer agents or between newer and older agents. Hypericum (St. John's wort) was more effective than placebo in treating mild to moderately severe depressive disorders (risk ratio 1.9, 95% CI 1.2 to 2.8). Whether hypericum (St. John's wort) is as effective as standard antidepressant agents given in adequate doses was not established. No significant differences were found between newer and older antidepressants in overall discontinuation rates. Selective serotonin reuptake inhibitors (SSRIs), reversi

Family planning in Mauritius: a national survey.

In the context of the Mauritian government's policy of encouraging fertility reduction, in 1975 the Ministry of Health requested the University of Mauritius to conduct the first national survey of contraceptive knowledge and use. The results for the 1,821 ever-married women under age 50 who were interviewed indicated high levels of knowledge and use of contraception. Nevertheless, there is still a need for increased efforts to retrieve dropouts and to improve the efficiency of contraceptive use.

Retroviral spongiform polioencephalomyelopathy.

Aging wild mice (Mus musculus domesticus) from several different trapping areas in southern California are uniquely prone to a naturally occurring hind-leg paralytic disease and/or lymphoma. Both conditions are caused by an indigenous ecotropic murine leukemia virus (MuLV). These mice have a lifelong persistent viremia with total immunologic tolerance to the virus. The characteristic pathologic features are centered on the anterior-lateral horns of the lumbosacral spinal cord and consist primarily of a noninflammatory spongiform change, with reactive gliosis and neuronal dropout. The main cause of neuronal death apparently is abortive intracytoplasmic replication of virus particles. Genetic control of the naturally occurring disease in wild mice is achieved by segregation of a dominant ecotropic virus restriction gene, Akvr-1R/Fv-4R. The neurologic and/or neoplastic diseases are readily reproduced by experimental inoculation of newborn susceptible laboratory mice with purified, cloned ecotropic virus derived from the affected wild mice. The biologic and pathologic features of the experimental paralysis closely resemble those of the natural disease. This nononcogenic retroviral disease is useful in understanding the molecular basis of direct, virus-induced, neuronal and glial cell degeneration and their sequelae.

Vocational rehabilitation in multiple sclerosis (MS): a profile of clients seeking services.

Although a number of innovative vocational rehabilitation (VR) demonstration projects have been completed with MS populations, there remains a lack of clarity as to a profile of these VR participants. An effort is made in this article to carefully describe the demographic and occupational characteristics of people with MS seeking vocational services at intake, as well as their self-perceived psychosocial functioning across a range of pertinent measures. The issue of "program dropouts" in VR services for people with MS is also addressed. Implications for better understanding participants with MS within the VR process and improved nuances in service delivery are then discussed.

Smoking stage of change is associated with retention in a smoke-free residential drug treatment program for women.

Prochaska and DiClemente's Transtheoretical Model predicts dropout from substance-abuse treatment. However, it is not known whether readiness to quit smoking is associated with attrition from drug treatment programs with smoking restrictions. This study examined the relationship between smoking characteristics, smoking stage of change, and both length of stay (LOS) and discharge type among 75 perinatal substance abusers attending a smoke-free residential treatment program. URICA scores predicted LOS (P=.0004) and discharge type (P=.01). Women in action and maintenance remained in treatment longer and were more likely to complete treatment compared to those in precontemplation. Findings were not accounted for by addiction severity. Women with little interest in quitting smoking may have difficulty adhering to smoking restrictions during treatment for other drug problems, resulting in increased attrition. Alternatively, smoking stage of change may be a "proxy" for overall readiness to change in this population.

Predictors of patient retention in a newly established methadone maintenance treatment programme.

AIMS: To identify predictors of patient retention in methadone maintenance. DESIGN: Prospective study. SETTING: Methadone maintenance treatment programme newly established in Geneva, Switzerland. PARTICIPANTS: All patients who initiated treatment between February 1991 and January 1995. MEASUREMENTS: Baseline patient characteristics, dose of methadone, year of enrollment and retention in treatment. FINDINGS: Overall, 111 patients contributed 164.4 person-years of follow-up. The retention rate was 84% after 12 months. In multivariate analysis, the risk of dropping out was significantly higher for patients who had been using opioids for < or = 7 years (relative hazard (RH) 3.0, 95% confidence interval (CI) 1.2-7.4), and for patients who had no stable income at baseline (RH 3.3, 95% CI 1.2-9.1). Dropouts were less frequent at the highest doses of methadone (65-110 mg/day, RH 1.0) than at middle doses (45-60 mg/day, RH 2.0, 95% CI 0.7-5.5) but, quite unexpectedly, dropouts were least likely at the lowest doses (15-40 mg/day, RH 0.5, 95% CI 0.1-1.8). Dropouts were more likely among patients who enrolled in the first (RH 6.2, 95% CI 2.3-16.7) and second (RH 1.9, 95% CI 0.6-5.6) years of the programme, compared with subsequent years (RH 1.0). CONCLUSIONS: Patients who have a long history of drug use and who have a stable income were more likely to stay in methadone maintenance treatment. Independent of patient characteristics, retention improved dramatically in the first years of programme functioning, suggesting that patient retention is a sensitive indicator of programme performance.
