OBJECTIVE: The objective was to investigate the impact of affective, social, behavioral, and cognitive factors on pediatric emergency department (PED) provider mood changes during clinical shifts, with the introduction of a novel on‐shift measure. METHODS: The nominal group technique was used to generate the ED experience survey (EDES), encompassing factors that may influence PED provider mood. Providers were alerted via experience sampling method to complete the EDES and positive and negative affect schedule at randomly generated times. Analyses were conducted using multilevel modeling of moods within shifts within persons. RESULTS: Measures were completed 221 times during 137 shifts by 52 PED providers. Positive mood tended to increase with higher self‐rated capacity to deal with challenging patient situations (p

Although evaluative thinking lies at the heart of what we do as evaluators and what we hope to promote in others through our efforts to build evaluation capacity, researchers have given limited attention to measuring this concept. We undertook a research study to better understand how instances of evaluative thinking may present in practice-based settings-specifically within four state asthma control programs funded by the Centers for Disease Control and Prevention's National Asthma Control Program. Through content analyses of documents as well as interviews and a subsequent focus group with four state asthma control programs' evaluators and program managers we identified and defined twenty-two indicators of evaluative thinking. Findings provide insights about what practitioners may wish to look for when they intend to build evaluative thinking and the types of data sources that may be more or less helpful in such efforts.

The young age of mothers of infants with gastroschisis, a congenital defect of the abdominal wall, suggested that deficient nutrition, with maternal-fetal competition for nutrients, could be a risk factor for gastroschisis. This population-based hypothesis-generating study consisted of 55 cases of gastroschisis and 182 matched controls. We assessed maternal nutrient intake during the trimester before conception with a self-reported food-frequency questionnaire and screened 38 nutrients to identify those most likely to be associated with gastroschisis. We used statistical classification trees to empirically generate cutpoints that determined the low and high levels of nutrient intakes corresponding to the risk of gastroschisis; cutpoints for most nutrients were similar to the corresponding recommended daily dietary allowances (RDAs). In univariate analysis, low intake of several nutrients emerged as the leading risk factors: carotenoids, e.g., alpha-carotene (odds ratio (OR) = 4.6; 95% confidence interval (CI) = 2.2-9.5), beta-carotene (OR = 3.1; 95% CI = 1.6-6.0); amino-acid compounds, e.g., total glutathione (OR = 3.5; 95% CI = 1.7-7.2); vitamin C (OR = 2.2; 95% CI = 1.5-7.8); vitamin E (OR = 2.3; 95% CI = 1.2-4.4); and minerals, fiber, and the fruit-and-vegetable group (OR = 3.1; 95% CI = 1.5-6.2). High intake of nitrosamines (OR = 2.4; 95% CI = 1.3-4.5) was also a good candidate. Many nutrient values were correlated and, in multivariate analysis, those most associated with gastroschisis were low alpha-carotene (OR = 4.3; 95% CI = 1.9-9.8), low total glutathione (OR = 3.3; 95% CI = 1.4-7.6), and high nitrosamines (OR = 2.6; 95% CI = 1.3-5.4). Adjusting for variables associated with gastroschisis in previous analyses of this population did not substantially alter those risks. These results suggest that maternal dietary inadequacy may be a risk factor for gastroschisis, and the three nutrients that emerged from the nutrient screening appear to be the best candidates to examine in further epidemiological analyses or biological studies.

In a case-control study of gastroschisis, we evaluated the risks associated with mother's first-trimester use of medications and with hobby or occupational exposures for 110 cases and 220 controls without a birth defect. Mothers of cases and controls were age-matched. For hobby or occupational exposures, we found significantly elevated risks for high levels of solvents (odds ratio (OR) = 3.8; 95% confidence interval (CI) = 1.6-9.2) and for colorants (OR = 2.3; 95% CI = 1.3-4.0). For medications, we found significantly elevated risks for two strong cyclooxygenase inhibitors, aspirin (OR = 4.7; 95% CI = 1.2-18.1) and ibuprofen (OR = 4.0; 95% CI = 1.0-16.0), but not for acetaminophen, a weak cyclooxygenase inhibitor. Periconceptional exposure to X rays was also associated with gastroschisis (OR = 2.5; 95% CI = 1.2-5.5), but exposure to antibiotics, antinauseants, sulfonamides, or oral contraceptives was not. We also found elevated risks for two decongestants, pseudoephedrine (OR = 2.1; 95% CI = 0.8-5.5) and phenylpropanolamine (OR = 10.0; 95% CI = 1.2-85.6). For the group of all decongestants, including also oxymetazoline and ephedrine, the risk was significantly elevated (OR = 2.4; 95% CI = 1.0-5.4). Controlling in multivariate analyses for several demographic and pregnancy variables associated with gastroschisis in a previous analysis [Torfs et al. (1994) Teratology 50: 44-53] did not substantially change the level or direction of the associations. Most of these associations are for vasoactive substances, which supports a vascular hypothesis for the pathogenesis of gastroschisis.
