Community Preventive Health Education Intervention for Pediatric Iron-Deficiency Anemia in Rural Southeast Nigeria.

Objectives: Iron-deficiency anemia (IDA) is a global cause of morbidity in children under five, particularly in sub-Saharan Africa. In southeast Nigeria, poor dietary intake and caregiver knowledge about childhood anemia are observed; however, there is no consensus on how to best prevent it. This study seeks to test the effectiveness of caregiver education on improving anemia knowledge and dietary prevention strategies and promoting sustainable lifestyle changes to reduce the prevalence of childhood IDA. Study Design: A questionnaire was administered to the primary caregivers of 41 patients under age five with anemia in southeast Nigeria regarding socioeconomic status (SES), diet diversity, and risk factors for anemia. Caregivers were administered a preeducation questionnaire, poster education on anemia and iron-rich foods, and a posteducation questionnaire. All patients underwent a medical exam to confirm a diagnosis of anemia or anemia-related conditions. Results: Ninety-five percent of patients had moderate diet diversity, but there was no correlation between diet diversity and SES. Barriers to healthier diets were associated with SES. Preeducation scores were not associated with caregivers' education levels; however, posteducation scores were significantly higher in university-educated than technical-trained caregivers. Caregiver-reported self-efficacy increased after the education program. Conclusion: Caregivers' SES was associated with financial and knowledge barriers to a healthier diet but not diet diversity, suggesting that nutritional education could benefit all SES groups. Overall, the education program increased caregivers' anemia knowledge across educational levels. A community-based health education program could improve caregivers' anemia knowledge and self-efficacy in applying this information and potentially reduce this area's pediatric IDA.

Efficacy of Levetiracetam and Phenobarbital as First-Line Treatment for Neonatal Seizures.

High neonatal seizure burden is associated with worsened neurodevelopmental outcomes. We compared the efficacy of initial treatment with levetiracetam vs phenobarbital for maintaining low seizure burden in a retrospective cohort of 25 neonates monitored with video electroencephalography (EEG). Video EEG tracing were reviewed and paired with medication bolus times to determine seizure burden after treatment. Initial cumulative dose of phenobarbital was 20 mg/kg in all but 1 case; initial cumulative dose of levetiracetam ranged from 50 to 100 mg/kg. Eleven of 17 (65%) patients sustained seizure burden <10% following initial treatment with levetiracetam, compared with 5 of 8 (63%) with phenobarbital. Thirteen (76%) patients treated with levetiracetam had sustained seizure burden <20% compared with 6 (75%) treated with phenobarbital. The phenobarbital group showed a larger absolute reduction in average seizure burden in the hour before and after treatment (-24.3  vs -14.2 minutes/h). Six of 17 (35%) patients treated with levetiracetam remained seizure free after initial treatment, compared with 2 of 8 (25%) patients treated with phenobarbital. Initial treatment with levetiracetam was associated with shorter average time to seizure freedom (15 vs 21 hours). None of these results were statistically significant. Cumulative doses of levetiracetam 100 mg/kg were well tolerated and associated with substantial decrease in seizure burden in several cases. Levetiracetam remains a promising first-line treatment for neonatal seizures; additional randomized controlled trials evaluating the effects of high-dose levetiracetam on seizure burden and long-term outcomes are warranted.

The Use of Alveolar Dead Space Fraction to Predict Postoperative Outcomes after Pediatric Cardiac Surgery: A Retrospective Study.

Patients with congenital heart disease (CHD) that have surgical repair with cardiopulmonary bypass (CPB) reflect a unique population with multiple pulmonary and systemic factors that may contribute to increased alveolar dead space and low cardiac output syndrome. This study aimed to assess and compare changes in the alveolar dead space fraction (AVDSf) in the immediate postoperative period with outcomes in children with CHD who underwent repair on CPB. A single-center retrospective review study of critically ill children with CHD, younger than 18 years of age admitted to the Pediatric Intensive Care Unit (PICU) after undergoing surgical repair on CPB and received invasive mechanical ventilation for at least 24 h. One hundred and two patients were included in the study. Over the first 24 h, mean AVDSf was significantly higher in patients who had longer hospital length of stay (LOS) (> 21 days) p = 0.02, and longer duration of invasive mechanical ventilation (DMV) (> 170 h) p = 0.01. Cross-sectional analyses at 23-24 h revealed that AVDSf > 0.25 predicts mortality and DMV (p = 0.03 and P = 0.02 respectively); however, it did not predict prolonged hospital LOS. For every 0.1 increase in the AVDSf, the odds of mortality, DMV, and hospital LOS increased by 4.9 [95% CI = 1.45-16.60, p = 0.002], 2.06 [95% CI = 1.14-3.71, p = 0.01], and 1.43[95% CI = 0.84-2.45, p = 0.184], respectively. The area under the ROC curve at 23-24 h for AVDSf was 0.868 to predict mortality as an outcome. AVDSf > 0.25 at 23-24 h postoperatively was an independent predictor of mortality with sensitivity and specificity of 83% and 80%, respectively and was superior to other commonly used surrogates of cardiac output. In the immediate postoperative period of pediatric patients with CHD, high AVDSf is associated with longer hospital length of stay and duration of invasive mechanical ventilation. Increased AVDSf values at 23-24 h postoperatively is associated with mortality in patients with CHD exposed to CPB.

Reduction of cardiac dose using respiratory-gated MR-linac plans for gastro-esophageal junction cancer.

Treatment of locally advanced adenocarcinoma of the gastroesophageal junction (GEJ) with chemoradiation may be associated with high rates of symptomatic cardiac toxicity. Large margins are typically required to ensure coverage of GEJ tumors with free-breathing volumetric modulated arc therapy (VMAT) radiotherapy. The purpose of this study is to determine whether treatment with tighter margins enabled by maximum-inhalation breath hold (MIBH)-gated intensity modulated radiation therapy (IMRT) on an integrated MRI-linear accelerator system (MR-linac) can decrease radiation doses to the heart and cardiac substructures. Ten patients with locally advanced GEJ adenocarcinoma underwent both free breathing 4-dimensional computed tomography (4DCT) and MIBH MRI simulation scans. MR-linac IMRT plans were created with a 3 mm clinical target volume (CTV) to planning target volume (PTV) isotropic margin and 4DCT VMAT plans were created with a 11, 13, and 9 mm CTV to PTV anisotropic margins in the left-right, cranial-caudal, and anterior-posterior directions according to GEJ-specific PTV expansion recommendations by Voncken et al. Prescription dose to PTV was 50.4 Gy in 28 fractions. Dosimetry to the heart and cardiac substructures was compared with paired t test; p < 0.05 was considered significant. Mean PTV on the MR-linac IMRT plans was significantly smaller compared to the 4DCT VMAT plans (689 cm3vs 1275 cm3, p < 0.01). Mean dose to the heart and all cardiac substructures was significantly lower in the MR-linac IMRT plans compared to the 4DCT VMAT plans: heart 20.9 Gy vs 27.8 Gy, left atrium 29.6 Gy vs 39.4 Gy, right atrium 20.5 Gy vs 25.6 Gy, left ventricle 21.6 Gy vs 29.6 Gy, and right ventricle 18.7 Gy vs 25.2 Gy (all p values <0.05). MIBH-gated MR-linac IMRT treatment of locally advanced GEJ adenocarcinoma can significantly decrease doses to the heart and cardiac substructures and this may translate to reduced rates of cardiac toxicity.

Reliability and validity of PROMIS® pediatric family relationships short form in children 8-17 years of age with chronic disease.

PURPOSE: Families play a key role in managing pediatric chronic illness. The PROMIS® pediatric family relationships measure was developed primarily within the general pediatric population. We evaluated the Family Relationships short form in the context of pediatric chronic diseases. METHODS: Children aged 8-17 years with asthma (n = 73), type 1 diabetes (n = 122), or sickle cell disease (n = 80) completed the Family Relationships 8a short form and the PROMIS Pediatric Profile-25's six domains representing physical, mental, and social health. Parents (N = 275) of these children completed the parent versions of the same measures. We evaluated reliability of the Family Relationships measure using Cronbach's alpha and IRT-based marginal reliability, and the standard error of measurement (SEM). Convergent/discriminant validity were assessed from correlations between the Family Relationships domain and the PROMIS-25 domains. RESULTS: SEM increased for scores above the normative mean of 50. Cronbach's alpha and IRT-estimated marginal reliabilities exceeded 0.80 for children and parents across diseases, except in asthma, where marginal reliability was 0.75 for parents. Scores displayed small to large correlations in the expected directions with social and mental health domains. The largest correlations occurred with parents' proxy reports of children's depressive symptoms in sickle cell disease and asthma, r = - 0.60 (95% CI - 0.74, - 0.48) and r = - 0.58 (95% CI - 0.68, - 0.48) respectively. CONCLUSIONS: The Family Relationships 8-item short form demonstrated adequate reliability and convergent/discriminant validity for use in pediatric chronic conditions, though scores above the mean displayed greater uncertainty. Evidence of the measure's reliability and validity in multiple contexts furthers the case for its use.

Outcomes in children undergoing posterior fossa decompression and duraplasty with and without tonsillar reduction for Chiari malformation type I and syringomyelia: a pilot prospective multicenter cohort study.

OBJECTIVE: Despite significant advances in diagnostic and surgical techniques, the surgical management of Chiari malformation type I (CM-I) with associated syringomyelia remains controversial, and the type of surgery performed is surgeon dependent. This study's goal was to determine the feasibility of a prospective, multicenter, cohort study for CM-I/syringomyelia patients and to provide pilot data that compare posterior fossa decompression and duraplasty (PFDD) with and without tonsillar reduction. METHODS: Participating centers prospectively enrolled children suffering from both CM-I and syringomyelia who were scheduled to undergo surgical decompression. Clinical data were entered into a database preoperatively and at 1-2 weeks, 3-6 months, and 1 year postoperatively. MR images were evaluated by 3 independent, blinded teams of neurosurgeons and neuroradiologists. The primary endpoint was improvement or resolution of the syrinx. RESULTS: Eight clinical sites were chosen based on the results of a published questionnaire intended to remove geographic and surgeon bias. Data from 68 patients were analyzed after exclusions, and complete clinical and imaging records were obtained for 55 and 58 individuals, respectively. There was strong agreement among the 3 radiology teams, and there was no difference in patient demographics among sites, surgeons, or surgery types. Tonsillar reduction was not associated with > 50% syrinx improvement (RR = 1.22, p = 0.39) or any syrinx improvement (RR = 1.00, p = 0.99). There were no surgical complications. CONCLUSIONS: This study demonstrated the feasibility of a prospective, multicenter surgical trial in CM-I/syringomyelia and provides pilot data indicating no discernible difference in 1-year outcomes between PFDD with and without tonsillar reduction, with power calculations for larger future studies. In addition, the study revealed important technical factors to consider when setting up future trials. The long-term sequelae of tonsillar reduction have not been addressed and would be an important consideration in future investigations.

Impact of family-centered tailoring of pediatric diabetes self-management resources.

BACKGROUND: The American Diabetes Association recommends a family-centered approach that addresses each family's specific type 1 diabetes self-management barriers. OBJECTIVE: To assess an intervention that tailored delivery of self-management resources to families' specific self-management barriers. SUBJECTS: At two sites, 214 children 8-16 years old with type 1 diabetes and their parent(s) were randomized to receive tailored self-management resources (intervention, n = 106) or usual care (n = 108). METHODS: Our intervention (1) identified families' self-management barriers with a validated survey, (2) tailored self-management resources to identified barriers, and (3) delivered the resources as four group sessions coordinated with diabetes visits. Mixed effects models with repeated measures were fit to A1c as well as parent and child QOL during the intervention and 1 year thereafter. RESULTS: Participants were 44% youth (8-12 years) and 56% teens (13-16 years). No intervention effect on A1c or QOL was shown, combining data from sites and age groups. Analyzing results by site and age group, post-intervention A1c for teens at one site declined by 0.06 more per month for intervention teens compared to usual care (P < 0.05). In this group, post-intervention A1c declined significantly when baseline A1c was >8.5 (-0.08, P < 0.05), with an even larger decline when baseline A1c was >10 (-0.19, P < 0.05). In addition, for these teens, the significant improvements in A1c resulted from addressing barriers related to motivation to self-manage. Also at this site, mean QOL increased by 0.61 points per month more during the intervention for parents of intervention youth than for usual care youth (P < 0.05). CONCLUSIONS: Tailored self-management resources may improve outcomes among specific populations, suggesting the need to consider families' self-management barriers and patient characteristics before implementing self-management resources.

Diabetic Retinopathy Assessment Variability Among Eye Care Providers in an Urban Teleophthalmology Program.

BACKGROUND: Teleophthalmology is an evidence-based method for diabetic eye screening. It is unclear whether the type of eye care provider performing teleophthalmology interpretation produces significant variability. INTRODUCTION: We assessed grading variability between an optometrist, general ophthalmologist, and retinal specialist using images from an urban, diabetic retinopathy teleophthalmology program. METHODS: Three readers evaluated digital retinal images in 100 cases (178 eyes from 90 patients with type 2 diabetes). Fisher's exact test, percent agreement, and the observed proportion of positive (Ppos) or negative agreement (Pneg) were used to assess variability. RESULTS: Among cases deemed gradable by all three readers (n = 65), there was substantial agreement on absence of any retinopathy (88% ± 4.6%, Pneg = 0.91-0.95), presence of moderate nonproliferative or worse retinopathy (87% ± 3.9%, Ppos = 0.67-1.00), and presence of macular edema (99% ± 0.9%, Ppos = 0.67-1.00). There was limited agreement regarding presence of referable nondiabetic eye pathology (61% ± 11%, Ppos = 0.21-0.59) and early, nonroutine referral for a follow-up clinical eye exam (66% ± 8.1%, Ppos = 0.19-0.54). Among all cases (n = 100), there was acceptable agreement regarding which had gradable images (77% ± 5.0%, Ppos = 0.50-0.90). DISCUSSION: Inclusion of multiple types of eye care providers as teleophthalmology readers is unlikely to produce significant variability in the assessment of diabetic retinopathy among high-quality images. Greater variability was found regarding image gradability, nondiabetic eye pathology, and recommended clinical referral times. CONCLUSIONS: Our results suggest that more extensive training and uniform referral standards are needed to improve consensus on image gradability, referable nondiabetic eye pathology, and recommended clinical referral times.

Effects of hetastarch 130/0.4 on plasma osmolality, colloid osmotic pressure and total protein in horses anaesthetised for elective surgical procedures.

Effects of lactated Ringer's solution (LRS) and hetastarch 130/0.4 (HES) on colloid osmotic pressure (COP), plasma osmolality (OSM) and total protein (TP) were investigated in 18 inhalational-anaesthetised healthy horses. Horses received 4-6 ml/kg LRS (LRS; n=9) or HES (HES; n=9) from anaesthesia induction through 60 min, after which all were administered LRS. COP, TP and OSM were measured before premedication (baseline), postinduction and 30 (n=18), 60 (n=18), 90 (n=18) and 120 (n=12) minutes. Baseline COP, OSM and TP were not different between groups. TP decreased in both groups at all time points after induction. OSM increased from baseline in HES at 30, 60, 90 and 120 minutes. COP decreased at 30-120 minutes in LRS, and at 90 and 120 minutes in HES. Mean COP was higher in HES than LRS at 30 (18.8±0.5 vs 16.3±0.4 mmHg (P=0.001)), 60 (19.1±0.5 vs 15.9±0.4 mmHg (P<0.0001)) and 90 (17.4±0.5 vs 15.4±0.5 mmHg (P=0.005)) minutes. Sixty minutes of HES infusion increases OSM and transiently maintains COP compared with an equal volume of LRS in anaesthetised horses.

Are Parents Who Feel the Need to Watch Over Their Children's Care Better Patient Safety Partners?

OBJECTIVES: Many parents report needing to watch over their child's hospital care to prevent mistakes. In this study, we assessed whether needing to watch over care predicts parent performance of recommended safety behaviors to reduce medication errors and health care-associated infections. METHODS: At admission, we surveyed 170 parents about their need to watch over care, demographics, and hospitalization factors. At discharge, parents were surveyed about medication awareness and hand hygiene behaviors. Logistic regression was used to examine how parents' need to watch over care predicted each behavior, adjusting for demographics and hospitalization factors. RESULTS: Thirty-eight percent of parents reported needing to watch over care. Most parents (77%) reported frequently or very frequently asking providers for drug names or doses. Fewer parents asked to check drug or infusion accuracy (29%) or to show or read aloud medication labels (21%). Few parents reminded providers to clean hands (4%), but most stated they would be comfortable asking (82%) and likely to speak up if a provider did not (78%). After adjustment, parents needing to watch over care were significantly more likely to ask providers to check drug or infusion accuracy (adjusted odds ratio = 4.59, 95% confidence interval 2.14-9.94) and for drug name or dose (adjusted odds ratio = 3.04, 95% confidence interval 1.25-7.39). CONCLUSIONS: Parents who report the need to watch over care are more likely to perform behaviors specific to safe medication use (but not hand hygiene) compared with those not reporting this need. Opportunities exist to engage parents as safety partners by leveraging their need to watch over care toward system-level safety initiatives.

A Family-Centered Rounds Checklist, Family Engagement, and Patient Safety: A Randomized Trial.

BACKGROUND AND OBJECTIVES: Family-centered rounds (FCRs) have become standard of care, despite the limited evaluation of FCRs' benefits or interventions to support high-quality FCR delivery. This work examines the impact of the FCR checklist intervention, a checklist and associated provider training, on performance of FCR elements, family engagement, and patient safety. METHODS: This cluster randomized trial involved 298 families. Two hospital services were randomized to use the checklist; 2 others delivered usual care. We evaluated the performance of 8 FCR checklist elements and family engagement from 673 pre- and postintervention FCR videos and assessed the safety climate with the Children's Hospital Safety Climate Questionnaire. Random effects regression models were used to assess intervention impact. RESULTS: The intervention significantly increased the number of FCR checklist elements performed (ß = 1.2, P < .001). Intervention rounds were significantly more likely to include asking the family (odds ratio [OR] = 2.43, P < .05) or health care team (OR = 4.28, P = .002) for questions and reading back orders (OR = 12.43, P < .001). Intervention families' engagement and reports of safety climate were no different from usual care. However, performance of specific checklist elements was associated with changes in these outcomes. For example, order read-back was associated with significantly more family engagement. Asking families for questions was associated with significantly better ratings of staff's communication openness and safety of handoffs and transitions. CONCLUSIONS: The performance of FCR checklist elements was enhanced by checklist implementation and associated with changes in family engagement and more positive perceptions of safety climate. Implementing the checklist improves delivery of FCRs, impacting quality and safety of care.

Family Engagement in Pediatric Sickle Cell Disease Visits.

Adults with sickle cell disease (SCD) report problems in relationship building and information exchange during clinic visits. To explore the origin of these communication challenges, we compare communication in pediatric SCD, diabetes, and asthma visits. We collected visit videos and parent surveys from 78 children ages 9-16 years with SCD, asthma, or diabetes. Coders assessed child, parent, and physician utterances reflecting relationship building, information giving, and information gathering. Associations of engagement with type of chronic disease visit were performed with negative binomial regression. Compared to SCD visits, children in diabetes visits spoke 53% more relationship-building utterances (p < .05) and physicians in asthma visits spoke 48% fewer relationship building utterances to the child (p < .01). In diabetes visits, physicians gave almost twice as much information to children and gave 48% less information to parents (both p < .01) compared to SCD visits. Compared to SCD visits, physicians spoke fewer information-gathering utterances to parents in diabetes and asthma visits (85% and 72% respectively, both p < .001). SCD visits reflect less engagement of the children and greater physician effort to gather information from parents. These differences highlight opportunities to enhance engagement as a mechanism for ultimately improving SCD care.

Relationships among aeroallergen sensitization, peripheral blood eosinophils, and periostin in pediatric asthma development.

BACKGROUND: Biomarkers, preferably noninvasive, that predict asthma inception in children are lacking. OBJECTIVE: Little is known about biomarkers of type 2 inflammation in early life in relation to asthma inception. We evaluated aeroallergen sensitization, peripheral blood eosinophils, and serum periostin as potential biomarkers of asthma in children. METHODS: Children enrolled in the Childhood Origins of ASThma study were followed prospectively from birth. Blood samples were collected at ages 2, 4, 6, and 11 years, and serum-specific IgE levels, blood eosionophil counts, and periostin levels were measured in 244 children. Relationships among these biomarkers, age, and asthma were assessed. RESULTS: Serum periostin levels were approximately 2- to 3-fold higher in children than previously observed adult levels. Levels were highest at 2 years (145 ng/mL), and did not change significantly between 4 and 11 years (128 and 130 ng/mL). Age 2 year periostin level of 150 ng/mL or more predicted asthma at age 6 years (odds ratio [OR], 2.3; 95% CI, 1.3-4.4). Eosinophil count of 300 cells/µL or more and aeroallergen sensitization at age 2 years were each associated with increased risk of asthma at age 6 years (OR, 3.1; 95% CI, 1.7-6.0 and OR, 3.3; 95% CI, 1.7-6.3). Children with any 2 of the biomarkers had a significantly increased risk of developing asthma by school age (≥2 biomarkers vs none: OR, 6.6; 95% CI, 2.7-16.0). CONCLUSIONS: Serum periostin levels are significantly higher in children than in adults, likely due to bone turnover, which impairs clinical utility in children. Early life aeroallergen sensitization and elevated blood eosinophils are robust predictors of asthma development. Children with evidence of activation of multiple pathways of type 2 inflammation in early life are at greatest risk for asthma development.

Trends in the Use of Medical Imaging to Diagnose Appendicitis at an Academic Medical Center.

OBJECTIVE: To quantify the trends in imaging use for the diagnosis of appendicitis. METHODS: A retrospective study covering a 22-year period was conducted at an academic medical center. Patients were identified by International Classification of Diseases-9 diagnosis code for appendicitis. Medical record data extraction of these patients included imaging test used (ultrasound, CT, or MRI), gender, age, and body mass index (BMI). The proportion of patients undergoing each scan was calculated by year. Regression analysis was performed to determine whether age, gender, or BMI affected imaging choice. RESULTS: The study included a total of 2,108 patients, including 967 (43.5%) females and 599 (27%) children (<18 years old). CT use increased over time for the entire cohort (2.9% to 82.4%, P < .0001), and each subgroup (males, females, adults, children; P < .0001 for each). CT use increased more in females and adults than in males and children, but differences in trends were not statistically significant (male versus female, P = .8; adult versus child, P = .1). The percentage of patients who had no imaging used for the diagnosis of appendicitis decreased over time (P < .0001 overall and for each subgroup), and no difference was found in trends between complementary subgroups (male versus female, P = .53; adult versus child, P = .66). No statistically significant changes were found in use of ultrasound or MRI over the study period. With increasing BMI, CT was more frequently used. CONCLUSIONS: Of those diagnosed with appendicitis at an academic medical center, CT use increased more than 20-fold. However, no statistically significant trend was found for increased use of ultrasound or MRI.

Updated Outcomes of Prophylactic Femoral Fixation.

Despite an increasing number of patients with metastatic bone disease (MBD), minimal data exist regarding outcomes of patients undergoing prophylactic femoral fixation for MBD when compared with other frequently performed orthopedic operations, such as hemiarthroplasty of the femur. The authors performed a retrospective database review evaluating these procedures due to similar operative times and patient populations and also reviewed common comorbidities such as body mass index (BMI). The goal was to provide updated results of prophylactic femoral fixation and evaluate whether certain patient risk factors (eg, BMI) altered 30-day survival for patients with MBD. The authors reviewed 1849 patients with and without MBD treated by prophylactic fixation and hemiarthroplasty from 2006 to 2011 identified in the American College of Surgeons National Surgical Quality Improvement Program database. There were no significant differences in complications between patients undergoing surgical treatment for impending or actual femoral fracture. In addition, there were no differences between the 217 patients with MBD in either the hemiarthroplasty or prophylactic fixation groups because the rate of death within 30 days postoperatively was 5.56% and 3.30%, respectively (P=.526). When comparing BMI, obese patients had higher rates of wound infection, and underweight patients were more likely to develop pneumonia or die within 30 days postoperatively. Patients with impending femur fractures benefit from prophylactic fixation and perform as well in the short term as patients undergoing hemiarthroplasty. Certain BMI categories (underweight or obese) contributed to poorer outcomes. These findings provide updated information for discussing risks and benefits with surgical candidates.

Sex-related differences in pulmonary physiologic outcome measures in a high-risk birth cohort.

BACKGROUND: Sex influences the risk of wheezing illnesses and the prevalence of asthma throughout childhood. OBJECTIVE: To better understand the mechanisms of these effects, we analyzed longitudinal relationships between sex, lung physiology, and asthma in the Childhood Origins of ASThma birth cohort study. METHODS: Childhood Origins of ASThma birth cohort study children were followed prospectively from birth and assessed annually. Results of spirometry, fractional exhaled nitric oxide (Feno), mannitol provocation testing, and (3)He gas magnetic resonance imaging were assessed by sex using multivariate models including age, asthma diagnosis, and wheezing histories. RESULTS: Girls had higher prebronchodilator forced expiratory volume in 0.5 seconds/forced vital capacity values than did boys (mean difference, 0.017; 95% CI, 0.000-0.034; P = .05) of equivalent age. Postbronchodilator findings were more pronounced, with boys demonstrating reduced forced expiratory volume in 0.5 seconds/forced vital capacity values than did girls of equivalent age (mean difference, 0.032; 95% CI, 0.014-0.049; P = .0005). Conversely, girls were noted to have higher ventilation defects on (3)He magnetic resonance imaging than did boys (P = .01). No differences were noted in the rate of positive responses to mannitol provocation or Feno measurements. CONCLUSIONS: Lower airflow values are present by spirometry for prepubertal boys than for age-matched girls; however, greater (3)He ventilation defects were noted in girls. This could represent a greater degree of subclinical air trapping in prepubertal girls because residual volumes are not detected on standard spirometric readings. No differences were noted between the 2 sexes with airway hyperresponsiveness (mannitol provocation testing) or inflammation (Feno). Prospective peripubertal follow-up will determine whether these differences persist or change with the de novo expression and remission of asthma based on sex and age.

Family-initiated dialogue about medications during family-centered rounds.

BACKGROUND AND OBJECTIVE: Experts suggest family engagement in care can improve safety for hospitalized children. Family-centered rounds (FCRs) can offer families the opportunity to participate in error recovery related to children's medications. The objective of this study was to describe family-initiated dialogue about medications and health care team responses to this dialogue during FCR to understand the potential for FCR to foster safe medication use. METHODS: FCR were video-recorded daily for 150 hospitalized children. Coders sorted family-initiated medication dialogue into mutually exclusive categories, reflecting place of administration, therapeutic class, topic, and health care team responses. Health care team responses were coded to reflect intent, actions taken by the team, and appropriateness of any changes. RESULTS: Eighty-three (55%) of the 150 families raised 318 medication topics during 347 FCR. Most family-initiated dialogue focused on inpatient medications (65%), with home medications comprising 35%. Anti-infectives (31%), analgesics (14%), and corticosteroids (11%) were the most commonly discussed medications. The most common medication topics raised by families were scheduling (24%) and adverse drug reactions (11%). Although most health care team responses were provision of information (74%), appropriate changes to the child's medications occurred in response to 8% of family-initiated dialogue, with most changes preventing or addressing adverse drug reactions or scheduling issues. CONCLUSIONS: Most families initiated dialogue regarding medications during FCRs, including both inpatient and home medications. They raised topics that altered treatment and were important for medication safety, adherence, and satisfaction. Study findings suggest specific medication topics that health care teams can anticipate addressing during FCR.

Development and validation of PRISM: a survey tool to identify diabetes self-management barriers.

AIMS: Although most children with type 1 diabetes do not achieve optimal glycemic control, no systematic method exists to identify and address self-management barriers. This study develops and validates PRISM (Problem Recognition in Illness Self-Management), a survey-based tool for efficiently identifying self-management barriers experienced by children/adolescents with diabetes and their parents. METHODS: Adolescents 13 years and older and parents of children 8 years and older visiting for routine diabetes management (n=425) were surveyed about self-management barriers. HbA1c was abstracted from the electronic health record. To develop PRISM, exploratory and confirmatory factor analyses were used. To assess validity, the association of PRISM scores with HbA1c was examined using linear regression. RESULTS: Factor analyses of adolescent and parent data yielded well-fitting models of self-management barriers, reflecting the following domains: (1) Understanding and Organizing Care, (2) Regimen Pain and Bother, (3) Denial of Disease and Consequences, and (4) Healthcare Team, (5) Family, or (6) Peer Interactions. All models exhibited good fit, with χ(2) ratios<2.21, root mean square errors of approximation<0.09, Confirmatory Fit Indices and Tucker-Lewis Indices both >0.92, and weighted root mean square residuals<1.71. Greater PRISM barrier scores were significantly associated with higher HbA1cs. CONCLUSIONS: Our findings suggest at least six different domains exist within self-management barriers, nearly all of which are significantly related to HbA1c. PRISM could be used in clinical practice to identify each child and family's unique self-management barriers, allowing existing self-management resources to be tailored to the family's barriers, ultimately improving effectiveness of such services.
