Randomized Controlled Trial
The effect of Valerian on the severity and frequency of hot flashes: A triple-blind randomized clinical trial.
Valerian is one of the most widely used herbal supplements and a phytoestrogenic herb. The aim of this study was to determine the effect of Valerian on the severity and frequency of hot flashes. This triple-blind, randomized, controlled clinical trial was conducted during a three-month period in Hamadan, Iran, in 60 postmenopausal women aged 45-55 years. ⋯ The severity of hot flashes in the Valerian group was significantly lower than that in the placebo group at one (p = .048) and two months (p = .020) after initiation of the intervention. Compared with the placebo group, the mean frequency of hot flashes was significantly reduced two months after initiating the use of Valerian (p = .033). Health-care providers should consider Valerian to be effective for menopausal women with hot flashes.

Randomized Controlled Trial
Efficacy of an HIV/STI sexual risk-reduction intervention for African American adolescent girls in juvenile detention centers: a randomized controlled trial.
Few HIV/STI interventions exist for African American adolescent girls in juvenile detention. The objective was to evaluate the efficacy of an intervention to reduce incident STIs, improve HIV-preventive behaviors, and enhance psychosocial outcomes. We conducted a randomized controlled trial among African American adolescent girls (13-17 years, N = 188) in juvenile detention from March 2011 to May 2012. ⋯ At the 6-month assessment (3-months post-intervention), Imara participants reported higher condom use self-efficacy (p < 0.001), HIV/STI knowledge (p < 0.001), and condom use skills (p < 0.001) compared to control participants. No significant differences were observed between trial conditions in incident Chlamydia or gonorrhea infections, condom use, or number of vaginal sex partners. Imara for detained African American adolescent girls can improve condom use skills and psychosocial outcomes; however, a critical need for interventions to reduce sexual risk remains.
