Choosing a screening tool to assess disordered eating in adolescents with type 1 diabetes mellitus

[Extract] Disturbed eating behaviours and insulin omission in adolescents with type 1 diabetes mellitus have concerned diabetes clinicians for decades, yet screening and management protocols using validated tools for this high risk group are lacking. Clinical eating disorders and milder forms of disordered eating can impact negatively on glycaemic control and are associated with serious health consequences (Rydall et al., 1997). Early detection and treatment of disturbed eating thoughts and behaviours is important (Goebel-Fabbri, 2009)

Long‐term outcomes after paediatric sepsis (LOTUS)–A protocol for an Australian cohort study

Background: Globally, sepsis has been identified as one of the leading causes of preventable childhood mortality and morbidity. Previous studies on intensive care patients estimated that approximately 30% of children with sepsis experience some form of disability at discharge. Development of care has seen growing numbers of children treated for sepsis not requiring a PICU admission; however, outcomes in this population are yet to be understood. Further focus is required to understand sepsis survivorship across the wider population to address knowledge gaps and morbidity burden in the broader surviving population. Aims: To assess the cognitive, physical, emotional and social health of children surviving sepsis 2 years after hospital discharge. Study design: A prospective, observational cohort study. Results: Two hundred and thirty-two children will be screened, 2 years after their hospital admission, and approached for participation in this study. Children who are <18 years of age at follow-up, treated for sepsis-related organ dysfunction or septic shock in Queensland between October 2018 and December 2019, will be included. Children who are deceased at follow-up, under care of the state, or require English interpreters will be excluded from participation. Data will be collected through an online follow-up survey comprising validated caregiver-reported questionnaires covering the four Post Intensive Care Syndrome-paediatrics (PICS-p) domains (cognitive, physical, emotional and social health; Manning et al. Pediatr Crit Care Med, 2018, 19, 298-300). The primary outcome is an adaptive behaviour of the participants assessed using the Vinelands-3 tool. Secondary outcomes will include neurodevelopment, quality of life, child distress, overall function, executive function, caregiver's distress and caregiver's stress. Analysis of variance (ANOVA), Kruskal-Wallis and Fisher's exact test/chi-squared tests will be used for statistical analyses. No adjustments will be made for multiple comparisons but it is acknowledged that comparisons made in this study are exploratory. Relevance to clinical practice: With more children surviving sepsis, there is a need for a more comprehensive assessment of patient and family outcomes to allow support structures for families leaving the hospital after sepsis. This study is expected to inform clinicians and stakeholders of patient and family well-being after sepsis survivorship

Serum Levels of Vitamin C and Thiamin in Children With Suspected Sepsis: A Prospective Observational Cohort Study

OBJECTIVES: Vitamin C and thiamin have been trialed as adjunctive therapies in adults with septic shock but their role in critically ill children is unclear. We assessed serum levels of vitamin C and thiamin in children evaluated for sepsis. DESIGN: Single-center prospective observational study. Serum levels of vitamin C and thiamin were measured on admission and association with multiple organ dysfunction syndrome (MODS) was explored using logistic regression. SETTING: Emergency department and PICU in a tertiary children’s hospital, Queensland, Australia. PATIENTS: Children greater than 1 month and less than 17 years evaluated for sepsis. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: Vitamin levels were determined in 221 children with a median age of 3.5 (interquartile range [IQR] 1.6, 8.3) years. Vitamin C levels were inversely correlated with severity as measured by pediatric Sequential Organ Failure Assessment (Spearman’s rho = –0.16, p = 0.018). Median (IQR) vitamin C levels on admission were 35.7 (17.9, 54.1) µmol/L, 36.1 (21.4, 53.7) µmol/L, and 17.9 (6.6, 43.0) µmol/L in children without organ dysfunction, single organ dysfunction, and MODS, respectively (p = 0.017). In multivariable analyses, low levels of vitamin C at the time of sampling were associated with greater odds of MODS (adjusted odds ratio [aOR] 3.04; 95% CI, 1.51–6.12), and vitamin C deficiency was associated with greater odds of MODS at 24 hours after sampling (aOR 3.38; 95% CI, 1.53–7.47). Median (IQR) thiamin levels were 162 (138, 192) nmol/L, 185 (143, 200) nmol/L, and 136 (110, 179) nmol/L in children without organ dysfunction, single organ dysfunction, and MODS, respectively (p = 0.061). We failed to identify an association between thiamin deficiency and either MODS at sampling (OR 2.52; 95% CI, 0.15–40.86) or MODS at 24 hours (OR 2.96; 95% CI, 0.18–48.18). CONCLUSIONS: Critically ill children evaluated for sepsis frequently manifest decreased levels of vitamin C, with lower levels associated with higher severity

Aromatherapy for treatment of postoperative nausea and vomiting (Review)

Background: Postoperative nausea and vomiting (PONV) is a common, unpleasant phenomenon and current therapies are not always effective for all patients. Aromatherapy has been suggested as an addition to the available treatment strategies. This review was originally published in 2012 and updated in 2017. Objectives: The main objective was to establish the efficacy and safety of aromatherapy comparable to standard pharmacological treatments for PONV in adults and children. Search methods: We searched CENTRAL; MEDLINE; Embase; CINAHL; CAM on PubMed; Informit; LILACS; and ISI Web of Science as well as grey literature sources and the reference lists of retrieved articles up to March 2017. The original search was performed in August 2011. Selection criteria: We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) where aromatherapy was used to treat PONV. Interventions were all types of aromatherapy compared to placebo or with standard antiemetics. Primary outcomes were severity and duration of PONV. Secondary outcomes were adverse reactions, use of rescue antiemetics and patient satisfaction. Data collection and analysis: Two review authors independently assessed risk of bias in the included studies and extracted data. For dichotomous outcome variables, we used a random-effects model and calculated risk ratio (RR) with associated 95% confidence interval (95% CI). For continuous outcome variables, we used a random-effects model and calculated standardized mean difference (SMD) with associated 95% CI. We used the GRADE software to compile 'Summary of findings' tables. Main results: We included seven new studies with 663 participants in the 2017 update; five RCTs and two CCTs. These were added to the nine previously included studies (six RCTs and three CCTs with a total of 373 participants) for a total of 16 included studies and 1036 participants in this updated review. The mean age and range data for all participants were not reported for all studies. We identified two registered trials that met the inclusion criteria for this review; however there are no results for these studies yet. Overall, the GRADE assessment of evidence quality ranged from moderate to very low. The method of randomization in 11 of the 12 included RCTs was explicitly stated and adequate. Incomplete or methodologically diverse reporting of data affected the completeness of the analysis. Data on additional aromatherapies were added in the 2017 update (blended aromatherapy products, and peppermint products). Heterogeneity of outcome measures and time points between studies affected the completeness of the analysis. In the summary of the findings of six studies, we did not find aromatherapy to be effective in reducing nausea severity in comparison to placebo (SMD -0.22, 95% CI -0.63 to 0.18, P value = 0.28, 241 participants, level of evidence: low). Those participants receiving aromatherapy were no more likely to be free of nausea at the end of the treatment period than those receiving placebo (RR 3.25, 95% CI 0.31 to 34.33, P value = 0.33, 4 trials, 193 participants, evidence level: very low), however they were less likely to require rescue antiemetics (RR 0.60, 95% CI 0.37 to 0.97, P value = 0.04, 7 trials, 609 participants, evidence level: low). There were no data reported on adverse events or patient satisfaction for this comparison. A specific comparison of peppermint aromatherapy to placebo did not show evidence of an effect on nausea severity at five minutes post-treatment in the pooled results (SMD -0.18, 95% CI -0.86 to 0.49, P value = 0.59, 4 trials, 115 participants, evidence level: low). There were no data reported on nausea duration, use of rescue antiemetics, adverse events or patient satisfaction for this comparison. When we pooled studies comparing isopropyl alcohol to standard antiemetic treatment in a GRADE summary of findings, in terms of nausea duration, there was a significant effect on the time in minutes to a 50% reduction in nausea scores (SMD -1.10, 95% CI -1.43 to -0.78, P value < 0.00001, 3 trials, 176 participants, evidence level: moderate). Fewer participants who received isopropyl alcohol required rescue antiemetics (RR 0.67, 95% CI 0.46 to 0.98, P value = 0.04, 215 participants, 4 trials, evidence level: moderate). Two studies with 172 participants measured patient satisfaction; there were high levels of satisfaction across both aromatherapy and standard treatment groups and no differences found (evidence level: low). There were no data reported on nausea severity or adverse events for this comparison. There was no difference in effectiveness between isopropyl alcohol vapour inhalation and placebo for reducing the proportion of participants requiring rescue antiemetics (RR 0.39, 95% CI 0.12 to 1.24, P value = 0.11, 291 participants, 4 trials, evidence level: very low). There were no data reported on nausea severity, nausea duration, adverse events or patient satisfaction for this comparison. Authors' conclusions: Overall, for nausea severity at the end of treatment, aromatherapy may have similar effectiveness to placebo and similar numbers of participants were nausea-free. However, this finding is based on low-quality evidence and therefore very uncertain. Low-quality evidence also suggests that participants who received aromatherapy may need fewer antiemetic medications, but again, this is uncertain. Participants receiving either aromatherapy or antiemetic medications may report similar levels of satisfaction with their treatment, according to low-quality evidence

Early high flow nasal cannula therapy in bronchiolitis, a prospective randomised control trial (protocol): A Paediatric Acute Respiratory Intervention Study (PARIS)

Background Bronchiolitis imposes the largest health care burden on non-elective paediatric hospital admissions worldwide, with up to 15 % of cases requiring admission to intensive care. A number of previous studies have failed to show benefit of pharmaceutical treatment in respect to length of stay, reduction in PICU admission rates or intubation frequency. The early use of non-invasive respiratory support devices in less intensive scenarios to facilitate earlier respiratory support may have an impact on outcome by avoiding progression of the disease process. High Flow Nasal Cannula (HFNC) therapy has emerged as a new method to provide humidified air flow to deliver a non-invasive form of positive pressure support with titratable oxygen fraction. There is a lack of high-grade evidence on use of HFNC therapy in bronchiolitis. Methods/Design Prospective multi-centre randomised trial comparing standard treatment (standard subnasal oxygen) and High Flow Nasal Cannula therapy in infants with bronchiolitis admitted to 17 hospitals emergency departments and wards in Australia and New Zealand, including 12 non-tertiary regional/metropolitan and 5 tertiary centres. The primary outcome is treatment failure; defined as meeting three out of four pre-specified failure criteria requiring escalation of treatment or higher level of care; i) heart rate remains unchanged or increased compared to admission/enrolment observations, ii) respiratory rate remains unchanged or increased compared to admission/enrolment observations, iii) oxygen requirement in HFNC therapy arm exceeds FiO2 ≥ 40 % to maintain SpO2 ≥ 92 % (or ≥94 %) or oxygen requirement in standard subnasal oxygen therapy arm exceeds >2L/min to maintain SpO2 ≥ 92 % (or ≥94 %), and iv) hospital internal Early Warning Tool calls for medical review and escalation of care. Secondary outcomes include transfer to tertiary institution, admission to intensive care, length of stay, length of oxygen treatment, need for non-invasive/invasive ventilation, intubation, adverse events, and cost. Discussion This large multicenter randomised trial will allow the definitive assessment of the efficacy of HFNC therapy as compared to standard subnasal oxygen in the treatment of bronchiolitis

Impact of parental and healthcare professional concern on the diagnosis of pediatric sepsis: a diagnostic accuracy study

Objective: The Surviving Sepsis Campaign recommends systematic screening for sepsis. Although many sepsis screening tools include parent or healthcare professional concern, there remains a lack of evidence to support this practice. We aimed to test the diagnostic accuracy of parent and healthcare professional concern in relation to illness severity, to diagnose sepsis in children. Design: This prospective multicenter study measured the level of concern for illness severity as perceived by the parent, treating nurse and doctor using a cross-sectional survey. The primary outcome was sepsis, defined as a pSOFA score >0. The unadjusted area under receiver-operating characteristic curves (AUC) and adjusted Odds Ratios (aOR) were calculated. Setting: Two specialised pediatric Emergency Departments in Queensland. Patients: Children aged 30 days to 18 years old that were evaluated for sepsis. Intervention: None. Main results: 492 children were included in the study, of which 118 (23.9%) had sepsis. Parent concern was not associated with sepsis (AUC 0.53, 95% CI: 0.46-0.61, aOR: 1.18; 0.89-1.58) but was for PICU admission (OR: 1.88, 95% CI: 1.17-3.19) and bacterial infection (aOR: 1.47, 95% CI: 1.14-1.92). Healthcare professional concern was associated with sepsis in both unadjusted and adjusted models (nurses: AUC 0.57, 95% CI-0.50, 0.63, aOR: 1.29, 95% CI: 1.02-1.63; doctors: AUC 0.63, 95% CI: 0.55, 0.70, aOR: 1.61, 95% CI: 1.14-2.19). Conclusions: While our study does not support the broad use of parent or healthcare professional concern in isolation as a pediatric sepsis screening tool, measures of concern may be valuable as an adjunct in combination with other clinical data to support sepsis recognition

Machine learning to predict poor school performance in paediatric survivors of intensive care: a population-based cohort study

Purpose: Whilst survival in paediatric critical care has improved, clinicians lack tools capable of predicting long-term outcomes. We developed a machine learning model to predict poor school outcomes in children surviving intensive care unit (ICU). Methods: Population-based study of children < 16 years requiring ICU admission in Queensland, Australia, between 1997 and 2019. Failure to meet the National Minimum Standard (NMS) in the National Assessment Program-Literacy and Numeracy (NAPLAN) assessment during primary and secondary school was the primary outcome. Routine ICU information was used to train machine learning classifiers. Models were trained, validated and tested using stratified nested cross-validation. Results: 13,957 childhood ICU survivors with 37,200 corresponding NAPLAN tests after a median follow-up duration of 6 years were included. 14.7%, 17%, 15.6% and 16.6% failed to meet NMS in school grades 3, 5, 7 and 9. The model demonstrated an Area Under the Receiver Operating Characteristic curve (AUROC) of 0.8 (standard deviation SD, 0.01), with 51% specificity to reach 85% sensitivity [relative Area Under the Precision Recall Curve (rel-AUPRC) 3.42, SD 0.06]. Socio-economic status, illness severity, and neurological, congenital, and genetic disorders contributed most to the predictions. In children with no comorbidities admitted between 2009 and 2019, the model achieved a AUROC of 0.77 (SD 0.03) and a rel-AUPRC of 3.31 (SD 0.42). Conclusion: A machine learning model using data available at time of ICU discharge predicted failure to meet minimum educational requirements at school age. Implementation of this prediction tool could assist in prioritizing patients for follow-up and targeting of rehabilitative measures.

Nitric Oxide on Extracorporeal Membrane Oxygenation in Neonates and Children (NECTAR Trial): Protocol for a Randomized Controlled Trial

Background Extracorporeal membrane oxygenation (ECMO) provides support for the pulmonary or cardiovascular function of children in whom the predicted mortality risk remains very high. The inevitable host inflammatory response and activation of the coagulation cascade due to the extracorporeal circuit contribute to additional morbidity and mortality in these patients. Mixing nitric oxide (NO) into the sweep gas of ECMO circuits may reduce the inflammatory and coagulation cascade activation during ECMO support. Objective The purpose of this study is to test the feasibility and safety of mixing NO into the sweep gas of ECMO systems and assess its effect on inflammation and coagulation system activation through a pilot randomized controlled trial. Methods The Nitric Oxide on Extracorporeal Membrane Oxygenation in Neonates and Children (NECTAR) trial is an open-label, parallel-group, pilot randomized controlled trial to be conducted at a single center. Fifty patients who require ECMO support will be randomly assigned to receive either NO mixed into the sweep gas of the ECMO system at 20 ppm for the duration of ECMO or standard care (no NO) in a 1:1 ratio, with stratification by support type (veno-venous vs veno-arterial ECMO). Results Outcome measures will focus on feasibility (recruitment rate and consent rate, and successful inflammatory marker measurements), the safety of the intervention (oxygenation and carbon dioxide control within defined parameters and methemoglobin levels), and proxy markers of efficacy (assessment of cytokines, chemokines, and coagulation factors to assess the impact of NO on host inflammation and coagulation cascade activation, clotting of ECMO components, including computer tomography scanning of oxygenators for clot assessments), bleeding complications, as well as total blood product use. Survival without ECMO and the length of stay in the pediatric intensive care unit (PICU) are clinically relevant efficacy outcomes. Long-term outcomes include neurodevelopmental assessments (Ages and Stages Questionnaire, Strength and Difficulties Questionnaire, and others) and quality of life (Pediatric Quality of Life Inventory and others) measured at 6 and 12 months post ECMO cannulation. Analyses will be conducted on an intention-to-treat basis. Conclusions The NECTAR study investigates the safety and feasibility of NO as a drug intervention during extracorporeal life support and explores its efficacy. The study will investigate whether morbidity and mortality in patients treated with ECMO can be improved with NO. The intervention targets adverse outcomes in patients who are supported by ECMO and who have high expected mortality and morbidity. The study will be one of the largest randomized controlled trials performed among pediatric patients supported by ECMO.

Development of a risk engine relating maternal glycemia and body mass index to pregnancy outcomes

To develop a risk "engine" or calculator, integrating the risks of hyperglycemia, maternal BMI and other basic demographic data commonly available at the time of the pregnancy oral glucose tolerance test (OGTT), to predict an individual's absolute risk of specific adverse pregnancy outcomes.Data from the Brisbane HAPO cohort was analysed using logistic regression to determine the relationship between four clinical outcomes (primary CS, birth injury, large-for-gestational age, excess neonatal adiposity) with different combinations of OGTT results and maternal demographics (age, height, BMI, parity). Existing sets of international GDM diagnostic criteria were also applied to the cohort.191 (15.3%) women were diagnosed as GDM by one or more existing criteria. All international criteria performed poorly compared to risk models utilising OGTT results only, or OGTT results in combination with maternal demographics.The risk engine's empirical performance on receiver - operator curve analysis was superior to the existing GDM diagnostic criteria tested. This concept shows promise for use in clinical practice, but further development is required

Does model of maternity care make a difference to birth outcomes for young women? A retrospective cohort study

BACKGROUND: Adolescent pregnancy is associated with adverse outcomes including preterm birth, admission to the neonatal intensive care unit, low birth weight infants, and artificial feeding
