Expanded HIV Screening Projected To Decrease Spread of the Virus

abril del 2014

Intensified screening for HIV among injection drug users receiving opioid agonist therapy could prevent more than twice as many new infections as current screening practice. A recent study based on mathematical modeling found that screening every 6 months instead of annually, and adding viral RNA testing to the currently used HIV antibody testing, could improve both effectiveness and cost-effectiveness.

Study: Treat Jail Detainees’ Drug Abuse To Lower HIV Transmission

Marzo del 2014

Active drug use before incarceration was associated with decreased engagement in HIV treatment among HIV-infected jail detainees. The severity of drug dependence correlated with worsening measures of engagement in HIV treatment. The study concludes that evidence-based treatment for drug abuse in jails may result in improved HIV treatment outcomes, which in turn could help slow HIV-transmission rates in the United States.

Teen mothers on three American Indian reservations improved on several measures of parenting after participating in Family Spirit, a home-visiting intervention developed with NIDA support. At 12 months postpartum, the women’s children exhibited reduced rates of emotional difficulties predicting later drug abuse and other behavioral problems. Infants at highest risk—those whose mothers had histories of drug abuse—benefited the most.

enero del 2014

Ketoprofen, an anti-inflammatory agent commonly prescribed to treat arthritis, reduces neuronal damage in rats that have been exposed to chronic stress and methamphetamine. If this finding of a recent NIDA-supported study extrapolates to humans, anti-inflammatory medications may gain a place in the treatment of methamphetamine addiction.
