The lead article discusses a study by Dr. Thomas Dishion of the Oregon Child and Family Center. Dr. Dishion found that preventive interventions that put high-risk youths into groups can, under certain circumstances, produce worse rather than better behavior.
Other articles include the first study to clearly show an association between cocaine exposure before birth and cognitive impairments in toddlers. Researchers at Case Western Reserve University found that nearly twice as many cocaine-exposed children scored in the mental retardation range of a test that assesses mental development compared to unexposed children. Also described is a study that found that when a group of monkeys were moved from isolation to cages with other monkeys and developed social hierarchies, the monkeys that became dominant developed higher brain dopamine levels and were significantly less inclined to self-administer cocaine than subordinate monkeys--a finding that may have implications for understanding the interaction between environmental factors and drug abuse vulnerability in humans. Monitoring the Future (MTF) survey results are reported showing that from 2001 to 2002 the use of MDMA (ecstasy), marijuana, and cigarettes declined among 8th-, 10th-, and 12th-graders. The finding that youths' opportunities to experiment with drugs in later drug use is also discussed.
NIDA NOTES, Volume 17, Issue 6
NIH Pub. No. 03-3478
The lead article discusses recent research on nicotine's effects on the brain's reward system. Adding to their knowledge of how nicotine directly stimulates this reward system, researchers have discovered that nicotine also indirectly stimulates two types of neurons that intensify the pleasure from smoking and makes it last longer.
In the Director's Column, Dr. Glen R. Hanson discusses NIDA's continued commitment to nicotine research. The column notes NIDA's research partnership with the National Institute of Mental Health to identify and develop pharmacological compounds for use in investigating the roles of specific neurochemical receptors in mood disorders and nicotine addiction. Also discussed is Translating Tobacco Addiction Research to Treatment, a NIDA initiative that supports the development of new treatment and prevention options.
Other articles on NIDA-funded research address cocaine's effect on blood components and the link to heart attack and stroke; middle schools' selection and implementation of drug prevention programs; the use of vouchers to reward naltrexone treatment for heroin-dependent patients; and sex differences in the success of strategies to reduce drug-seeking. News articles note Dr. Nora D. Volkow's appointment as the new NIDA Director, and the addition of four new Advisory Council members. The Tearoff page discusses Monitoring the Future findings of dramatic declines in adolescents' smoking in 2002.
Eight editions of the CTN Bulletin Board were distributed this period. The Bulletin Board is an electronic report on the activities of the various protocol teams and subcommittees of the CTN.
The CTN brochure "Successfully Including Women in Clinical Trials" was translated into Spanish and distributed throughout the Network.
The CTN brochure, "What is the CTN?" was revised and translated into Spanish.
Two new patient brochures written for the Smoking Cessation Protocol (CTN 0009) have been approved and printed for distribution to the clinical trial sites.
A revised CTN Directory was approved and printed during this period.
- Three new brochures for the TELE Protocol (CTN 0011) have been written and approved for printing and distribution.
- A pre-printed rolodex card was approved for the CTN and was distributed to node staff at the Albuquerque meeting in March 2003.
