RESUMO

The study's purpose was to evaluate an intervention to reduce fruit and vegetable food neophobia and influence attitudes and behaviors among children using a four-month, non-experimental, before-and-after intervention. Participants were children aged 5-11 years in an intervention school (IS) and a control school (CS). Children were offered fruit or vegetable samples weekly utilizing school-specific psychosocial and educational practices to encourage participation. The outcomes of interest included attitudes measured using a written survey-based food neophobia scale (FNS), behavioral observations, and an oral survey. The post-intervention IS FNS score was significantly lower compared to pre-intervention (p = 0.04). Repeated-measures ANOVA revealed a statistically significant overall effect of time (p = 0.006). School type-time interaction was not significant (p = 0.57). Pre-intervention observational data showed the proportions finishing and taking another fruit and vegetable sample were higher in the CS (p < 0.001 for both). Post-intervention, the proportions taking the vegetable (p = 0.007) and the fruit (p < 0.001) were higher in the IS. The percentage tasting the vegetable was higher in the CS (p = 0.009). Offering samples of produce in school lunchrooms may reduce food neophobia. This intervention is an inexpensive program that volunteers can quickly implement.

RESUMO

OBJECTIVES: To determine, in preclinical in vivo animal and in clinical studies, whether raloxifene (a selective oestrogen-receptor (ER) modulator that targets ER-beta and induces apoptosis in vitro in androgen-independent prostate cancer, AIPC cells) affects prostate cell differentiation, proliferation and carcinogenesis, and in the pilot phase II clinical trial, the response rate and duration of patients with AIPC treated with a daily oral dose of raloxifene. PATIENTS, MATERIALS AND METHODS: Tumour proliferation rate in response to raloxifene treatment, and molecular markers of cell cycle and apoptosis, were evaluated in established ER-beta-positive androgen-dependent (AD) CWR22 and AI CWRSA9 human xenograft prostate cancer models. Twenty-one patients with AIPC and evidence of disease progression were enrolled into the clinical trial and given daily oral raloxifene. RESULTS: There was significant growth inhibition by raloxifene in the ADPC and AIPC xenograft models (CWR22 68%, P < 0.010; CWRSA9 64%, P < 0.001), with no tumour regression. There was evidence of G1 arrest by increased p27kip1 expression in the raloxifene-treated group. Eighteen patients comprised the efficacy analysis, as three withdrew before the first evaluation. At the first evaluation, five men had stable disease and continued on the study for a median of five cycles. The longest response was 17 cycles. Drug related toxicity was minimal. CONCLUSION: Raloxifene has activity in xenograft models, slowing disease progression. This translated to possible disease stabilization in patients with AIPC. Further studies are warranted.
