Determine which sociodemographic factors are most associated with increased maternal perceived stress during pregnancy. Evaluate the association between maternal stress and plasma immune-mediator concentrations (IMCs). As part of a prospective, randomized clinical trial, 247 participants completed a Perceived Stress Scale survey (PSS-10) during each trimester of pregnancy. Blood samples were collected from participants and were analyzed for 25-hydroxyvitamin D (25(OH)D) concentration and for several IMCs: interferon-gamma, interleukins (IL-) IL-2, IL-4, IL-5, IL-10, vascular endothelial growth factor, c-reactive protein, and tumor necrosis factor alpha (TNF-α) (R&D Elisa). The potential associations between PSS-10 scores, sociodemographic factors, and IMCs were assessed. In bivariate analysis, participants who were not married and/or had high risk pregnancies were more likely to have increased PSS-10 scores (p<0.05). Increased PSS-10 scores were associated with higher serum concentrations of IL-2 and TNF-α, and decreased concentrations of IL-10 and 25(OH)D. In linear regression analysis, single marital status, high-risk pregnancy, IL-2, and TNF-α were independent predictors of PSS-10 scores. This study identifies specific sociodemographic factors that are associated with increased perceived stress during pregnancy. This study also provides evidence that increased perceived stress is associated with physiological changes as measured by changes in circulating IL-2, TNF-α, IL-10, and 25(OH)D concentrations.

Objective: To determine if improvement in Inhaled Corticosteroid (ICS) prescribing in the pediatric emergency department (PED) can be sustained after transition from intense intervention to low-intervention phase, and to determine ICS fill rates.Methods: A Quality Improvement (QI) project began in Aug 2012. Results through Feb 2014 were previously published. In Feb 2014 interventions were scaled back to determine the sustainability of QI success. Eligible patients included children aged 2–17 seen in the PED for asthma between Feb 2014 and Sept 2016. The primary change when moving to the low-intervention phase was stopping monthly attending feedback. The primary outcome was the proportion of patients who were prescribed an ICS at the time of PED discharge. The secondary objective of this study was to determine the proportion of patients who filled their ICS prescription in the 6 months following Emergency Department (ED) visit.Results: The goal rate of ICS prescribing was 75%. After transition to the low-intervention phase, the ICS prescribing rate was maintained at a median of 79% through Sept 2016. ICS fill rate in the first 30 days following ED visit was 89%, although this quickly fell to below 40% for months 2–6.Conclusions: The ICS prescribing rate remained the goal of 75% over a 2.5-year period after transition to a low-intervention phase. High ICS fill rates immediately after ED visit have been demonstrated. However, rapid decline in these rates over subsequent months suggests a need for future efforts to focus on long-term ICS adherence among children with ED visits for asthma.

Objective: In order to reduce invasive testing in newborns prior to discharge, we tested the direction of the correlation between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB), the likelihood of missing high TSBs with a raised threshold for confirmatory testing, and also calculated potential cost savings from fewer laboratory testing.Methods: We performed a cross-sectional analysis of single paired TcB and TSB results measured at 36 ± 2 h of life in neonates ≥37 weeks admitted only to the Level 1 nursery. TcB was measured using the BiliChek® meter.Results: Of the 552 infants, 512 (92.8%) had TSB levels below TcB values. Correlation between TcB and TSB was 0.69. If TSB confirmation was to be performed at 11.7 mg/dL (medium risk threshold for phototherapy), the negative predictive value was 99.4%, with a potential cost savings of $6555.00 ($1500.00 per 100 patients). Of the 495 infants with TcB <11.7 mg/dL, only 3 had TSB levels higher than 11.7 mg/dL, and none met phototherapy threshold for low risk infants.Conclusions: TcB screening at our institution has a high negative predictive value, and can be used as a stand-alone test until values are close to phototherapy threshold, thus reducing invasive testing and cost.

Background: Youth with asthma who have poor medication adherence, have limited access to care, and are frequently seen in the acute care setting are often termed "high risk." Objective: This study aimed to design and test the feasibility of using smartphone technology to assess contextual factors that may impact changes in daily medication adherence and to identify new symptom episodes among high-risk youth with asthma in their home environment. Methods: Youth aged 8-17 years with high-risk asthma from 2 children's hospitals were eligible for the 2-month study. An app was downloaded on participants' phones at enrollment. Daily text message (short message service) reminders were sent to complete ecological momentary assessment of asthma symptoms and other contextual factors such as emotional state using the app. Bluetooth inhaler devices were used to record timestamps of inhaler use with the ability to review and manually enter data. The acceptability was assessed with surveys, key informant interviews (KII), and frequency of days with asthma data. KII data were used in an iterative design approach to identify challenges, strengths, and suggestions for maximizing use. Generalized linear mixed modeling was used to preliminarily explore contextual factors associated with changes in daily adherence. Results: We enrolled 14 children aged 8-16 years (13/14, 93% were African Americans). Over the 2-month study period, participants reported coughing (42/110, 38%), wheezing (8/111, 7%), chest tightness (9/109, 8%), boredom (57/109, 52%), and 10 new asthma symptom episodes. The controller medication adherence was 30%, which increased significantly on days with asthma symptoms or boredom. Data were received on 89% (606/681) of study days. Surveys and KIIs suggest acceptability among youth and their caregivers. Challenges reported during the study included lost or damaged phones and available memory. Conclusions: Youth and their caregivers reported the acceptability of using smartphones for real-time asthma monitoring. Overall, the controller medication adherence was low but increased significantly on days with reported asthma symptoms or boredom, suggesting that daily contextual factors may be associated with a change in the adherence behavior.

Objective: This article aims to determine the association between maternal 25-hydroxy-vitamin D [25(OH)D] status and intake of hormonal oral contraceptive pills (OCPs) in women who are lactating., Study Design: Women who were exclusively breastfeeding participated in a randomized controlled trial assessing vitamin D supplementation at 400, 2,400, or 6,400 international unit (IU)/d from 1 month through 7 months postpartum. This observational, secondary analysis assessed whether OCPs were associated with maternal 25(OH)D concentrations in women who are lactating. Multivariate regression models were used to predict 25(OH)D concentrations and create parameter estimates for each variable., Results: In a bivariate analysis, the use of OCPs at 4 months was associated with increased serum 25(OH)D ( p  = 0.02). OCPs' use at 7 months was associated with a higher trend in 25(OH)D, but this finding was not statistically significant ( p  = 0.1). In a multivariate regression model at 4 months, independent positive predictors of 25(OH)D concentrations were the use of OCPs ( p  = 0.03) and treatment with vitamin D at 6,400 IU/d ( p ≤ 0.0001). Negative predictors were Black ( p  = 0.001) and Hispanic ( p  = 0.0001) race and ethnicity, and body mass index (BMI) greater than 30 ( p  = 0.0002). The same pattern occurred at 7 months, with more southern latitude as a positive independent predictor ( p  = 0.04) of 25(OH)D concentration., Conclusion: The use of OCPs was associated with greater 25(OH)D in women who are lactating. Additionally, treatment with vitamin D at 6,400 IU/d and southern latitude was associated with greater 25(OH)D in women who are lactating. Black and Hispanic race and ethnicity, and BMI greater than 30, were independently associated with lower 25(OH)D in women who are lactating., Key Points: · The association of OCP with serum 25(OH)D concentrations during postpartum lactation is unknown.. · OCPs' use was associated with higher 25(OH)D concentrations in postpartum women who are lactating.. · Treatment with vitamin D and southern latitude was associated with greater 25(OH)D in women who are lactating.. · Black and Hispanic, and BMI > 30 were associated with lower 25(OH)D in women who are lactating.. · Practitioners can counsel women who are lactating on OCPs' use and the positive effects on their 25(OH)D status.., Competing Interests: None declared., (Thieme.
