Implementing a Clinical Decision Support Tool to Increase Early Peanut Introduction Guidance.

BACKGROUND: General pediatric providers are the frontline for early peanut introduction discussions, but many feel ill-equipped to handle such discussions as guidelines have quickly changed. OBJECTIVE: We hypothesized that a clinical decision support (CDS) tool could improve peanut introduction discussions. METHODS: CDS tools were designed by stakeholders, improved through usability testing, and integrated into the current note templates. Based on queries of electronic health record (EHR), we did a pre-post performance evaluation of peanut introduction conversations, barriers for introduction, and percentage of 12-month WCC visits that had successfully introduced peanut. Providers completed surveys before and after intervention to assess awareness of early peanut introduction and comfort using CDS. RESULTS: Providers' awareness of early peanut introduction guidelines increased from 17.8% to 66.7% after the CDS tool was implemented. 79.1% were comfortable using the tool. The CDS tool improved peanut introduction conversations at the 4-month well-child (WCC) care visit from 2.4% to 81.2%, at the 6-month WCC visit from 3.0% to 84.2%, and at the 12-month WCC visit from 2.7% to 82.9%. 56.6% of families had a plan to introduce peanut at the 4-month WCC visit. Of those who did not have a plan, the most common barrier was family's unawareness of the benefits of early peanut introduction. At the 12-month visit, 62.8% of families had introduced peanut without concerns. CONCLUSION: A point-of-care CDS tool encouraged more discussions by general pediatric providers on early peanut introduction to all patients. CDS tools should be considered in quality improvement projects as an implementation method for the most up-to-date guidelines.

Exercise and Cyclic Light Preconditioning Protect Against Light-Induced Retinal Degeneration and Evoke Similar Gene Expression Patterns.

To compare patterns of gene expression following preconditioning cyclic light rearing versus preconditioning aerobic exercise. BALB/C mice were preconditioned either by rearing in 800 lx 12:12 h cyclic light for 8 days or by running on treadmills for 9 days, exposed to toxic levels of light to cause light-induced retinal degeneration (LIRD), then sacrificed and retinal tissue harvested. Subsets of mice were maintained for an additional 2 weeks and for assessment of retinal function by electroretinogram (ERG). Both preconditioning protocols partially but significantly preserved retinal function and morphology and induced similar leukemia inhibitory factor (LIF) gene expression pattern. The data demonstrate that exercise preconditioning and cyclic light preconditioning protect photoreceptors against LIRD and evoke a similar pattern of retinal LIF gene expression. It may be that similar stress response pathways mediate the protection provided by the two preconditioning modalities.

High-fat diet-induced alterations in the feeding suppression of low-dose nisoxetine, a selective norepinephrine reuptake inhibitor.

Central noradrenergic pathways are involved in feeding and cardiovascular control, physiological processes altered by obesity. The present studies determined how high-fat feeding and body weight gain alter the sensitivity to the feeding suppression and neural activation to a selective norepinephrine reuptake inhibitor, nisoxetine. Acute administration of nisoxetine (saline: 0, 3, 10, and 30 mg/kg; i.p.) resulted in a dose-dependent reduction in the 24 h refeeding response in male Sprague Dawley rats maintained on standard chow. In a similar fashion, nisoxetine resulted in reductions in blood pressure and a compensatory increase in heart rate. From these studies, the 3 mg/kg dose was subthreshold. In a separate experiment, however, 10 wk exposure to a high-fat diet (60% fat) resulted in weight gain and significant feeding suppression following administration of nisoxetine (3 mg/kg) compared with animals fed a control diet (10% fat). Nisoxetine (3 mg/kg) also resulted in greater neural activation, as measured by c-Fos immunohistochemistry, in the arcuate nucleus of the hypothalamus in animals exposed to the high-fat diet. Such data indicate acute nisoxetine doses that suppress food intake can impact cardiovascular measures. It also suggests that the feeding suppression to a low-dose nisoxetine is enhanced as a result of high-fat diet and weight gain.
