RESUMO
Objective: The Child Asthma Risk Assessment Tool (CARAT) identifies risk factors for asthma morbidity. We hypothesized that CARAT-identified risk factors (using a CARAT adapted for inpatient use) would be associated with future healthcare utilization and would identify areas for intervention.Methods: We reviewed CARAT data collected during pediatric asthma admissions from 2010-2015, assessing for risk factors in environmental, medical, and social domains and providing prompts for inpatient (specialist consultation or social services engagement) and post-discharge interventions (home care visit or home environmental assessment). Confirmatory factor analysis identified groups of CARAT-identified risk factors with similar effects on healthcare utilization (latent factors). Structural equation models then evaluated relationships between latent factors and future utilization.Results: There were 2731 unique patients admitted for asthma exacerbations; 1015 (37%) had complete CARAT assessments and were included in analyses. Those with incomplete CARAT assessments were more often younger and privately-insured. CARAT-identified risk factors across domains were common in children hospitalized for exacerbations. Risks in the environmental domain were most common. Inpatient asthma consults by pulmonologists or allergists and home care referrals were the most frequent interventions indicated (62%, 628/1015, and 50%, 510/1015, respectively). Two latent factors were positively associated with healthcare utilization in the year after index stay - social stressors and known/suspected allergies (both p < 0.05). Stratified analyses analyzing data just from those children with prior healthcare utilization also indicated known/suspected allergies to be positively associated with future utilization.Conclusions: Inpatient interventions to address social stressors and allergic profiles may be warranted to reduce subsequent asthma morbidity.

INTRODUCTION: Evidence about specific carbohydrate diet (SCD) for inflammatory bowel disease (IBD) is limited. We conducted 54 single-subject, double-crossover N-of-1 trials comparing SCD with a modified SCD (MSCD) and comparing each with the participant's baseline, usual diet (UD). METHODS: Across 19 sites, we recruited patients aged 7-18 years with IBD and active inflammation. Following a 2-week baseline (UD), patients were randomized to 1 of 2 sequences of 4 alternating 8-week SCD and MSCD periods. Outcomes included fecal calprotectin and patient-reported symptoms. We report posterior probabilities from Bayesian models comparing diets. RESULTS: Twenty-one (39%) participants completed the trial, 9 (17%) completed a single crossover, and 24 (44%) withdrew. Withdrawal or early completion occurred commonly (lack of response [n = 11], adverse events [n = 11], and not desiring to continue [n = 6]). SCD and MSCD performed similarly for most individuals. On average, there was <1% probability of a clinically meaningful difference in IBD symptoms between SCD and MSCD. The average treatment difference was -0.3 (95% credible interval -1.2, 0.75). There was no significant difference in the ratio of fecal calprotectin geometric means comparing SCD and MSCD (0.77, 95% credible interval 0.51, 1.10). Some individuals had improvement in symptoms and fecal calprotectin compared with their UD, whereas others did not. DISCUSSION: SCD and MSCD did not consistently improve symptoms or inflammation, although some individuals may have benefited. However, there are inherent difficulties in examining dietary changes that complicate study design and ultimately conclusions regarding effectiveness.

OBJECTIVES: Human leukocyte antigen-DP beta 1 (HLA-DPB1) with a glutamic acid at the 69th position of the ß chain (E69) genotype and inhalational beryllium exposure individually contribute to risk of chronic beryllium disease (CBD) and beryllium sensitisation (BeS) in exposed individuals. This retrospective nested case-control study assessed the contribution of genetics and exposure in the development of BeS and CBD. METHODS: Workers with BeS (n=444), CBD (n=449) and beryllium-exposed controls (n=890) were enrolled from studies conducted at nuclear weapons and primary beryllium manufacturing facilities. Lifetime-average beryllium exposure estimates were based on workers' job questionnaires and historical and industrial hygienist exposure estimates, blinded to genotype and case status. Genotyping was performed using sequence-specific primer-PCR. Logistic regression models were developed allowing for over-dispersion, adjusting for workforce, race, sex and ethnicity. RESULTS: Having no E69 alleles was associated with lower odds of both CBD and BeS; every additional E69 allele increased odds for CBD and BeS. Increasing exposure was associated with lower odds of BeS. CBD was not associated with exposure as compared to controls, yet the per cent of individuals with CBD versus BeS increased with increasing exposure. No evidence of a gene-by-exposure interaction was found for CBD or BeS. CONCLUSIONS: Risk of CBD increases with E69 allele frequency and increasing exposure, although no gene by environment interaction was found. A decreased risk of BeS with increasing exposure and lack of exposure response in CBD cases may be due to the limitations of reconstructed exposure estimates. Although reducing exposure may not prevent BeS, it may reduce CBD and the associated health effects, especially in those carrying E69 alleles.

OBJECTIVE: There is a lack of studies focusing on the use of health care facilities by homeless people. The aim of this study was to survey health care use by the homeless. METHODS: Data were taken from the Hamburg survey of homeless individuals (n=150, mean age:12,5 years; SD: 12,5 years). Assessment covered details of health insurance status, use of ambulatory and hospital care, medication use, and reasons for not accessing health services. RESULTS: In total, 61,2% of the homeless individuals had health insurance. About two thirds of homeless individuals (65,9%) had accessed some sort of medical services in the past 12 months. The key reason for not making use of health services was the absence of any need for treatment (74,6%). In sum, 39,8% of homeless individuals had made at least one hospital visit in the past 12 months. About one third (34,2%) had used mobile support services (mainly a mobile doctor's office). In total, 37,7% of homeless individuals took medications regularly, with 'prices too high' (63,6%) being the key reason for difficulties in access to medications. Almost one half of homeless individuals (47,0%) had not made a visit to a physician in the past three months. CONCLUSION: Additional efforts are required to improve access to health care by homeless individuals. Future research in this area is therefore necessary.

OBJECTIVE: To evaluate structural and functional carotid changes and inflammatory profiles in children with obstructive sleep apnea (OSA) and healthy controls. STUDY DESIGN: Patients with OSA and matched controls (ages 5-13 years) were recruited. Proinflammatory cytokines and acute phase reactants were measured at 6:00 p.m. Common carotid artery measures were determined using ultrasound. Confirmatory factor analysis was used to determine subgroups of cytokines and their effects on carotid measures. RESULTS: Ninety-six patients participated (53 healthy controls, 43 patients with OSA). OSA was associated with increased proinflammatory cytokines (cluster of differentiation-40 ligand [CD40-L], interleukin [IL]-6, and IL-8) and high sensitivity C-reactive protein (P < .05 for all). One cytokine subgroup (IL-6 and IL-8) was negatively associated with markers of carotid function, indicating reduced arterial distensibility and increased stiffness (P < .05 for 3 ultrasound measures); and tumor necrosis factor-α had an opposing effect on carotid function compared with this cytokine subgroup (P < .05 for 2 ultrasound measures). Linear regression demonstrated significant associations between and tumor necrosis factor- α and 2 measures of carotid function (P < .05 for each). Children with OSA did not have functional or structural carotid changes compared with controls. CONCLUSION: OSA was not directly associated with structural and functional carotid changes but was associated with upregulation of key proinflammatory cytokines (sCD40-L, IL-6, and IL-8). Together, IL-6 and IL-8 were associated with changes in carotid function. Longitudinal studies are needed to demonstrate that the inflammatory milieu observed in our population is a precursor of atherosclerosis in children.

Sarcoidosis and chronic beryllium disease (CBD) are phenocopies, however the latter one has a clear trigger factor that is beryllium exposure. This study analyses single nucleotide polymorphisms (SNPs) in a large cohort for beryllium-exposed persons. SNPs were chosen for their relevance in sarcoidosis. Even though one of largest cohorts of beryllium-exposed persons was analysed, no statistically relevant association between any SNP and CBD could be verified. Notably, some SNPs exhibit inverse OR for beryllium sensitization and CBD with nominally statistical significance, which allows hypothesizing about pathophysiological role of genes for the disease triggering and development.

BACKGROUND: The Composite Asthma Severity Index (CASI) is a comprehensive tool to assess asthma severity, which has been applied in the research setting. OBJECTIVE: To evaluate, in an outpatient setting, whether a CASI score accurately predicts asthma severity or control as determined by means of subspecialist assessment. Asthma Control Test (ACT) and childhood ACT (C-ACT) scores were generated to provide additional context for CASI scores in relationship to assessments using another clinical tool. METHODS: Children aged 5 to 18 years with a physician diagnosis of persistent asthma were recruited from a tertiary care center. A pediatric pulmonologist made determinations on each participant's asthma severity and control during a clinic visit. A CASI and ACT/C-ACT score was generated for each patient. Logistic regression and Spearman correlations were used to determine how well CASI scores predicted physician assessments. Agreement between ACT/C-ACT scores and physician assessment of asthma control was determined in supplemental analyses. RESULTS: CASI scores strongly predicted physician assessment of severity (Spearman correlation = 0.61, P < .001); unadjusted odds ratio (OR) equal to 36.67 (95% confidence interval [CI]: 8.83-152.34); and adjusted OR equal to 32.76 (95% CI: 85.70-188.44). In supplemental analyses, ACT/C-ACT scores strongly predicted physician assessment of control (Spearman correlation = 0.72, P < .001) with an unadjusted OR equal to 42.12 (95% CI: 13.34-133.00) and adjusted OR equal to 55.34 (95% CI: 13.62-224.89). CONCLUSION: Use of the CASI was feasible and accurately predicted physician assessments of asthma severity and control in this sample, which are not distinct entities. The CASI is a robust tool that may be used successfully in ambulatory pediatric asthma care.

BACKGROUND: To identify the determinants of health care use among homeless individuals. METHODS: Data were taken from the Hamburg survey of homeless individuals (n = 100 individuals in the here used model, mean age 44.8 years, SD 12.5) focusing on homeless individuals in Hamburg, Germany. The number of physician visits in the past 3 months and hospitalization in the preceding 12 months were used as outcome measures. Drawing on the Andersen model of health care use as a conceptual framework, predisposing characteristics, enabling resources and need factors as well as psychosocial variables were included as correlates. RESULTS: Negative binomial regressions showed that increased physician visits were associated with being female (IRR: 4.02 [95% CI: 1.60-10.11]), absence of chronic alcohol consume (IRR: 0.26 [95% CI: 0.12-0.57]) and lower health-related quality of life (IRR: 0.97 [95% CI: 0.96-0.98]). Furthermore, logistic regressions showed that the likelihood of hospitalization was positively associated with lower age (OR: 0.93 [95% CI: 0.89-0.98]), having health insurance (OR: 8.11 [2.11-30.80]) and lower health-related quality of life (OR: 0.97 [95% CI: 0.94-0.99]). CONCLUSIONS: Our study showed that predisposing characteristics (both age and sex), enabling resources (i.e., health insurance) and need factors in terms of health-related quality of life are main drivers of health care use among homeless individuals. This knowledge may assist in managing health care use.

Objective: Little is known about weight status and its effects on clinical course during hospitalization for asthma exacerbation. We sought to evaluate associations between weight status, specifically body mass index (BMI), with inpatient clinical course and clinical history.Methods: We retrospectively analyzed data from 2012 to 2013 on children hospitalized for asthma exacerbation in a state-wide longitudinal cohort, the Ohio Pediatric Asthma Repository. We examined BMI continuously (z scores) and categorically, comparing overweight and obese (Ov/Ob) to non-overweight and non-obese (nOv/nOb) children. We used linear mixed models controlling for site effects to determine if BMI was related to length of stay, as determined by physiologic readiness for discharge (PRD), defined as time to albuterol spaced every 4 h, need for nonstandard care or clinical history.Results: Across six hospitals, 874 children were included in analyses. BMI was positively associated with PRD (p=.008) but this increase was unlikely to be clinically significant. Ov/Ob children were more likely than nOv/nOb to require nonstandard care with repeat magnesium dosing in intensive care after dosing in the emergency department (OR = 3.23, 95%CI 1.39-7.78). Hospitalization in the year prior to enrollment was positively associated with BMI percentile (73.3 vs. 66.0, p=.028). Sleep disordered breathing was also associated with higher BMI percentile (78.2 vs. 65.9; p=.0013).Conclusions: Ov/Ob children had similar PRD to nOv/nOb children and were prone to repeat magnesium dosing. Previous hospitalization for exacerbation was positively associated with increasing BMI percentile. Additional research should investigate differential magnesium use by weight status, quantifying risks and benefits.

Work-related asthma is asthma that is caused or exacerbated by exposure to specific substances in the workplace. Approximately 10%-16% of adult-onset asthma cases are attributable to occupational factors, and estimates of asthma exacerbated by work range from 13% to 58%. During 2008-2012, the Massachusetts Department of Public Health received nine reports of work-related asthma among workers at a facility that manufactured syntactic foam used for flotation in the offshore oil and gas industry. These reports and a request from facility employees led to a CDC health hazard evaluation during 2012-2013 in which CDC reviewed records, toured the facility, and administered a questionnaire to current employees. Investigators found that workers' risk for asthma increased substantially after hire, possibly because of known asthma triggers (i.e., asthmagens) used in production. The company has since initiated efforts to reduce employee exposures to these substances. This cluster of work-related asthma was identified through CDC-funded, state-based surveillance and demonstrates complementary state and federal investigations.

RATIONALE: Beryllium continues to have a wide range of industrial applications. Exposure to beryllium can lead to sensitization (BeS) and chronic beryllium disease (CBD). OBJECTIVES: The purpose of this statement is to increase awareness and knowledge about beryllium exposure, BeS, and CBD. METHODS: Evidence was identified by a search of MEDLINE. The committee then summarized the evidence, drew conclusions, and described their approach to diagnosis and management. MAIN RESULTS: The beryllium lymphocyte proliferation test is the cornerstone of both medical surveillance and the diagnosis of BeS and CBD. A confirmed abnormal beryllium lymphocyte proliferation test without evidence of lung disease is diagnostic of BeS. BeS with evidence of a granulomatous inflammatory response in the lung is diagnostic of CBD. The determinants of progression from BeS to CBD are uncertain, but higher exposures and the presence of a genetic variant in the HLA-DP ß chain appear to increase the risk. Periodic evaluation of affected individuals can detect disease progression (from BeS to CBD, or from mild CBD to more severe CBD). Corticosteroid therapy is typically administered when a patient with CBD exhibits evidence of significant lung function abnormality or decline. CONCLUSIONS: Medical surveillance in workplaces that use beryllium-containing materials can identify individuals with BeS and at-risk groups of workers, which can help prioritize efforts to reduce inhalational and dermal exposures.

Multiple epidemiologic studies demonstrate associations between chronic beryllium disease (CBD), beryllium sensitization (BeS), and HLA-DPB1 alleles with a glutamic acid residue at position 69 (E69). Results suggest that the less-frequent E69 variants (non-*0201/*0202 alleles) might be associated with greater risk of CBD. In this study, we sought to define specific E69-carrying alleles and their amino acid sequences in the DP peptide binding groove, as well as their relationship to CBD and BeS risk, using the largest case control study to date. We enrolled 502 BeS/CBD subjects and 653 beryllium-exposed controls from three beryllium industries who gave informed consent for participation. Non-Hispanic white cases and controls were frequency-matched by industry. HLA-DPB1 genotypes were determined using sequence-specific primer PCR. The E69 alleles were tested for association with disease individually and grouped by amino acid structure using logistic regression. The results show that CBD cases were more likely than controls to carry a non-*02 E69 allele than an *02 E69, with odds ratios (95% confidence interval) ranging from 3.1 (2.1-4.5) to 3.9 (2.6-5.9) (p < 0.0001). Polymorphic amino acids at positions 84 and 11 were associated with CBD: DD versus GG, 2.8 (1.8-4.6), p < 0.0001; GD versus GG, 2.1 (1.5-2.8), p < 0.0001; LL versus GG, 3.2 (1.8-5.6), p < 0.0001; GL versus GG, 2.8 (2.1-3.8), p < 0.0001. Similar results were found within the BeS group and CBD/BeS combined group. We conclude that the less frequent E69 alleles confer more risk for CBD than does *0201. Recent studies examining how the composition and structure of the binding pockets influence peptide binding in MHC genes, as well of studies showing the topology of the TCR to likely bind DPB1 preferentially, give plausible biological rationale for these findings.

Parents' decisions about human papillomavirus (HPV) vaccine for sons may be influenced by potentially protecting sons' future female partners from HPV. We sought to identify characteristics of parents likely to consider future partner protection in vaccine decisions, and to determine if parents likely to consider future partners in vaccine decisions had greater intention to vaccinate. We performed a cross-sectional survey of parents with sons in a pediatric clinic in 2010. We used Fisher's exact tests to identify demographics associated with consideration of future female partners in vaccine decisions. We used adjusted logistic regression to determine if parents likely to consider future partner protection in vaccine decisions had greater intention to vaccinate sons. Most parents (76 %, 187/246) reported vaccine decisions for sons were likely to be influenced by preventing HPV transmission from sons to their female partners. Parents 40 years and older, White and Black parents (vs other race), non-Hispanic, and college-educated parents were significantly more likely to indicate female partner protection may influence vaccine decisions (p < 0.05). Parents likely to be influenced by female partner protection in vaccine decisions had greater intention to vaccinate sons than their counterparts (adjusted odds ratio 2.54, 95 % CI 1.22, 5.28). Overall, many parents were likely to consider sons' female partners in vaccine decisions. Because parents likely to consider female partners had increased intention to vaccinate sons, future efforts to improve vaccine uptake in boys should explore the benefits of highlighting potential female partner protection, as this concept may resonate with many parents.

Inhalation of beryllium is associated with the development of sensitization; however, dermal exposure may also be important. The primary aim of this study was to elucidate relationships among exposure pathways in four different manufacturing and finishing facilities. Secondary aims were to identify jobs with increased levels of beryllium in air, on skin, and on surfaces; identify potential discrepancies in exposure pathways, and determine if these are related to jobs with previously identified risk. Beryllium was measured in air, on cotton gloves, and on work surfaces. Summary statistics were calculated and correlations among all three measurement types were examined at the facility and job level. Exposure ranking strategies were used to identify jobs with higher exposures. The highest air, glove, and surface measurements were observed in beryllium metal production and beryllium oxide ceramics manufacturing jobs that involved hot processes and handling powders. Two finishing and distribution facilities that handle solid alloy products had lower exposures than the primary production facilities, and there were differences observed among jobs. For all facilities combined, strong correlations were found between air-surface (rp ≥ 0.77), glove-surface (rp ≥ 0.76), and air-glove measurements (rp ≥ 0.69). In jobs where higher risk of beryllium sensitization or disease has been reported, exposure levels for all three measurement types were higher than in jobs with lower risk, though they were not the highest. Some jobs with low air concentrations had higher levels of beryllium on glove and surface wipe samples, suggesting a need to further evaluate the causes of the discrepant levels. Although such correlations provide insight on where beryllium is located throughout the workplace, they cannot identify the direction of the pathways between air, surface, or skin. Ranking strategies helped to identify jobs with the highest combined air, glove, and/or surface exposures. All previously identified high-risk jobs had high air concentrations, dermal mass loading, or both, and none had low dermal and air. We have found that both pathways are relevant.

INTRODUCTION: Obstructive sleep apnea (OSA) in infants is treated with low flow oxygen via nasal cannula (NC), CPAP (continous positive airway pressure), or surgery. Literature supports the use of high flow NC (HFNC) in children in the outpatient setting, however there is limited data on the use of HFNC in infants. OBJECTIVE: The purpose of this study was to compare HFNC and low-flow oxygen as treatments for OSA in infants. METHODS: A prospective pilot study was performed at two institutions. Infants with primarily OSA underwent a 3-4 h sleep study with HFNC titration at 6-14 lpm for OSA, followed by clinical polysomnography (PSG) for oxygen titration (1/8-1 lpm). Infants with primarily central apnea were excluded. RESULTS: Nine infants were enrolled, with a mean age of 1.3 ± 1.7 months. Average apnea hypopnea index (AHI), average obstructive apnea hypopnea index (OAHI) and average central apnea index during the diagnostic PSG was 17.2 ± 7/h, 13.4 ± 5.4/h and 3.7 ± 4.8/h respectively. OSA improved in 44.4% of subjects with HFNC; the mean AHI and OAHI decreased from 15.6 ± 5.65/h and 12.8 ± 4.4/h on diagnostic PSG to 5.12 ± 2.5/h and 4.25 ± 2.5/h on titration PSG. OSA improved universally with low flow oxygen; the mean AHI decreased from 17.2 ± 7/h on diagnostic PSG to 4.44 ± 3.6/h on titration PSG. CONCLUSION: HFNC reduced OSA in some infants, though low flow oxygen reduced OSA in all subjects. Respiratory instability (high loop gain) in infants may explain why infants responded to low flow oxygen. More studies are needed to determine if HFNC is beneficial in selected groups of infants with OSA.
RESUMO
Importance: Pediatric data on inpatient home insulin pumps are absent in the literature. Understanding safety of home insulin pumps, managed by patients or caregivers, during times of illness will help diabetes technology securely move into pediatric hospitals. Objective: To examine whether insulin can be safely and accurately delivered to hospitalized children through home insulin pumps when managed by patients or caregivers. Design, Setting, and Participants: This single-center, retrospective, observational cohort study included children with insulin-dependent diabetes admitted to a tertiary children's hospital from January 1, 2016, to December 31, 2021. In all these patients, diabetes was the primary or secondary diagnosis on admission. Exposure: Insulin delivery via home insulin pump, hospital insulin pump, or subcutaneous injection. Main Outcomes and Measures: Hyperglycemia (glucose, >250 mg/dL) and hypoglycemia (glucose, <45 mg/dL) rates (quantified as the proportion of total insulin-days), glucose variability, and diabetic ketoacidosis (DKA) recurrences were compared for hospital pumps (manual mode), home pumps (manual mode), and subcutaneous injections using bivariate tests. Results: There were 18â¯096 insulin-days among 2738 patients aged 0.5 to 25 years (median age, 15.8 years [IQR, 12.3-18.3 years]). Overall, 990 (5.5%) of insulin-days involved hospital insulin pumps, and 775 (4.3%) involved home pumps. A total of 155 insulin-days (15.7%) involving hospital pumps were hyperglycemic, compared with 209 (27.0%) involving home pumps and 7374 (45.2%) involving injections (P < .001). Moderate hypoglycemia days comprised 31 insulin-days (3.1%) involving hospital pumps compared with 35 (4.5%) involving home pumps and 830 (5.1%) involving injections (P = .02). Severe hypoglycemia did not differ significantly according to insulin delivery method. Two patients using injections (0.01%) developed DKA; no patients using hospital or home pumps developed DKA. Conclusions and Relevance: In this cohort study, home insulin pump use was found to be safe in a children's hospital regarding hyperglycemia and hypoglycemia. These data support use of home insulin pumps during pediatric admissions in patients who do not require intensive care and without active DKA.

OBJECTIVE: Patients with cystic fibrosis (CF) often bring education-related concerns to their medical teams. Concerns around the ability for CF care teams to identify and address these concerns exist. We sought to describe CF care team perceptions of (1) patient and family education-related needs, (2) how these needs are identified, documented and addressed, and (3) education-related resource gaps. METHODS: A survey was emailed to pediatric care teams in the CF Foundation Care Center Network in April 2022. Individuals or care teams could complete the survey. Responses were aggregated for descriptive analysis. RESULTS: Sixty-seven programs responded representing 52% of United States pediatric CF centers. Most centers (88%) indicated social workers primarily address school concerns. Care teams often complete school forms (99%), coach families to communicate with schools (96%), communicate with schools directly (90%), and develop educational plans (76%). Formal education risk assessment and support programs are relatively uncommon (19%). Common student-specific needs include carrying medications (75%) and leaving class for gastrointestinal issues (54%). Needs reported are informational materials for families and schools (94%), staff education about school concerns and how to address them (91%), additional staff for education-related issues (65%), and expertise in education plan development (62%). CONCLUSION: CF care teams often lack comprehensive resources to identify and address education-related concerns. Systematically performing needs assessments, improving training for providers, and evaluating the benefits of education specialists on care teams may better identify and address education-related needs. Supporting educational progression will foster continued independence and well-being in adulthood.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) adversely affects normal blood pressure (BP) and may disrupt circadian BP patterns. We sought to examine 24-hour circadian BP rhythms in children with OSA and healthy controls. METHODS: Children 5-14 years with OSA and healthy controls underwent 24-hour BP monitoring and actigraphy to quantify sleep. Shape invariant statistical models compared circadian BP patterns (e.g. times of BP peaks, time arrived at peak BP velocity [TAPV]) in the OSA and control groups. RESULTS: The analytic sample included 219 children (mild OSA: nâ =â 52; moderate-to-severe OSA (MS-OSA): nâ =â 50; controls: nâ =â 117). In the morning, the MS-OSA group had earlier TAPV for DBP than controls (51 minutes, pâ <â 0.001). TAPV in the evening was earlier for the MS-OSA group than controls (SBP: 95 minutes, pâ <â 0.001; DBP: 28 minutes, pâ =â 0.028). At mid-day, SBP and DBP velocity nadirs were earlier for the MS-OSA group than controls (SBP: 57 minutes, pâ <â 0.001; DBP: 38 minutes, pâ <â 0.01). The MS-OSA group reached most BP values significantly earlier than controls; the largest differences were 118 minutes (SBP) and 43 minutes (DBP) (pâ <â 0.001). SBP and DBP were elevated in the MS-OSA group (hours 18-21 and 7--12, respectively, pâ <â 0.01) compared to controls. The MS-OSA group was prone to "non-dipping" compared to controls (SBP: odds ratio [OR]â =â 2.16, 95% CI: 1.09, 4.29; DBP: ORâ =â 3.45, 95% CI: 1.21, 10.23). CONCLUSIONS: Children with MS-OSA had changes in circadian BP patterns, namely earlier TAPV and BP peaks and nadirs than controls. Circadian disturbances in BP rhythms may be key to mapping the natural history of BP dysregulation in children with OSA.

BACKGROUND: Children with chronic medical conditions and their families have significant emotional health concerns, yet paediatricians are often ill-equipped to address these needs. The American Board of Pediatrics launched the Roadmap Project to better support emotional health as part of routine care. We present pilot work in paediatric training programmes to test educational approaches and explore lessons learned. APPROACH: Four institutions implemented Roadmap tools into their paediatric training programmes, either incorporating them into existing educational structures or embedding them into the clinical workplace. One programme utilised an existing longitudinal curriculum, and another incorporated into a block rotation. Two programmes embedded training for residents into a larger programme for the healthcare team within the clinical space, one in outpatient clinics and one in an inpatient service. EVALUATION: Evaluation strategies at each site matched the intended outcomes. Sites working within education programmes evaluated learners, demonstrating increases in resident skills and confidence on pre-/post-self-assessments. Sites embedding tools into the practice context measured changes in the clinical practice of the healthcare team. Despite variability in implementation, all approaches improved trainee skills; sites embedding education into a clinical setting saw greater changes in clinical practice. IMPLICATIONS: Our pilot provided structure yet allowed for flexibility, and all sites improved trainee skills. Engaging the entire healthcare team within practice settings appears advantageous, thus embedding education into clinical practice may be preferable to a separate education programme. Similar to outcomes found in interprofessional education (IPE), educating clinical teams together may be more impactful for cultural shifts needed for changing clinical practice.
