Blood lead level and dental caries in school-age children.
The association between blood lead level and dental caries was evaluated in cross-sectional analyses of baseline data for 543 children 6-10 years old screened for enrollment in the Children's Amalgam Trial, a study designed to assess potential health effects of mercury in silver fillings. Approximately half of the children were recruited from an urban setting (Boston/Cambridge, MA, USA) and approximately half from a rural setting (Farmington, ME, USA). Mean blood lead level was significantly greater among the urban subgroup, as was the mean number of carious tooth surfaces. Blood lead level was positively associated with number of caries among urban children, even with adjustment for demographic and maternal factors and child dental practices. This association was stronger in primary than in permanent dentition and stronger for occlusal, lingual, and buccal tooth surfaces than for mesial or distal surfaces. In general, blood lead was not associated with caries in the rural subgroup. The difference between the strength of the associations in the urban and rural settings might reflect the presence of residual confounding in the former setting, the presence of greater variability in the latter setting in terms of important caries risk factors (e.g., fluoride exposure), or greater exposure misclassification in the rural setting. These findings add to the evidence supporting a weak association between children's lead exposure and caries prevalence. A biologic mechanism for lead cariogenicity has not been identified, however. Our data are also consistent with residual confounding by factors associated with both elevated lead exposure and dental caries
Cancer control needs of 2-1-1 callers in Missouri, North Carolina, Texas, and Washington
Innovative interventions are needed to connect underserved populations to cancer control services. With data from Missouri, North Carolina, Texas, and Washington this study a) estimated the cancer control needs of callers to 2-1-1, an information and referral system used by underserved populations, b) compared rates of need to state and national data, and c) examined receptiveness to needed referrals. From October 2009 to March 2010 callers’ (N = 1408) cancer control needs were assessed in six areas: breast, cervical, and colorectal cancer screening, HPV vaccination, smoking, and smoke-free homes using Behavioral Risk Factor Surveillance System (BRFSS) survey items. Standardized estimates were compared to state and national rates. Nearly 70% of the sample had at least one cancer control need. Needs were greater for 2-1-1 callers compared to state and national rates, and callers were receptive to referrals. 2-1-1 could potentially be a key partner in efforts to reduce cancer disparities

Revisiting a non-significant findings study: A parent mentor intervention trial as exemplar
The purpose of this paper is to describe an interactive process for revising a parent social support intervention study with non-significant quantitative findings but strong clinical significance. We will present the methodological challenges that were problematic in the original intervention that potentially contributed to the non-significant findings, and a revised plan of action for conducting a future parent social support intervention. Of note, we have reconsidered the theory used to frame the original study, the randomization process, the intervention clarity and fidelity plan, what measures would better capture the effect, and the development of a more robust analysis plan that considers intra-family correlation, mediation and moderation (mixed model analysis). We will present the revision for each of these methods supported by recent empirical literature. Although this process may not be appropriate for all non-significant interventions, it should be considered with any study that has clinical significance
