RESUMEN
AIM: To assess participation with a structured transition programme for adolescents with diabetes. METHODS: Data from a regional cohort aged less than 16 years of age with type 1 (T1) and type 2 diabetes (T2D) in Auckland, New Zealand (2006-2016). Participation was defined as opting into a structured transition programme. RESULTS: Five hundrend and twelve adolescents who were to be transferred to adult care (476 type 1 (T1D) and 36 type 2 (T2D)), overall participation rate of 83%, 86% (408/476) with T1D compared to 47% (17/36) with T2D. Within the cohort of T1D, participation rates for Maori and Pacific were lower (74% and 77%, respectively) than New Zealand Europeans (88%, p = 0.020 and p = 0.039, respectively). Lower socio-economic status was associated with reduced participation (77%) compared to higher socio-economic status (90%, p = 0.002). Of the 476 T1D who participated, 408 (96%) subsequently attended at least one adult service clinic ("capture"). 42% attended an adult clinic within the planned 3 months, 87% at 6 months and retention in adult clinics over 5 years of follow-up was 78%. By contrast, the 68 young people with T1D who did not participate in the structured transition had a capture rate of 78% (p < 0.001) and retention of 63% (p = 0.036). CONCLUSIONS: In adolescents with diabetes, a formal transition from a paediatric service was associated with high rates of adult capture and subsequent retention in adult care over a 5-year follow-up period. Low socio-economic status, Maori or Pacific ethnicity and T2D were associated with reduced participation in the structured transition programme.

Mother-Baby Unit research has focussed on maternal psychopathology over the course of an admission. Less is known about the baby's well-being, the shared relationship, or the mother's recovery. In an initial sample of 45 women, we describe discharge and post-discharge outcomes for maternal psychopathology (using maternal report and the Global Assessment of Function, GAF) and the mother-infant relationship (using the Child and Adult Relational Experimental Index, CARE Index). Three months post-discharge, one third of women described themselves as "completely recovered," one third were experiencing significant deterioration and 17% were readmitted to inpatient care. Poorer GAF scores were associated with a clinical diagnosis of comorbid personality disorder, antenatal presence of the index illness, partner illicit substance use, maternal perception of her bond, infant social withdrawal, and child protection concern. Post-discharge, the mother-infant relationship results were concerning. Only 17% were regarded as adequate. Improvement was observed across this period in 56% but relational deterioration occurred for 35%. Maternal and relational outcomes were weakly correlated at discharge (r² = 0.29, p = 0.07) but this was lost post-discharge (r² = 0.03, p = 0.89). The shared relationship and infant mental health should both be targets for intervention; both during MBU admission, and post-discharge.
La investigación sobre la Unidad de Madres y Bebés se han enfocado en la sicopatología materna a lo largo del curso de una admisión. Se conoce menos del bienestar del bebé, la relación entre ellos o la presente recuperación de la madre. En un grupo muestra inicial de 45 mueres, describimos resultados posteriores a cuando se les dio de alta en cuanto a la sicopatología materna (usando el reporte materno y la Evaluación Global de la Función, GAF) y la relación infante-madre (usando el Índice de Relación Experimental entre Niño y Adulto, Índice CARE). Tres meses después de que se les dio de alta, un tercio de las mujeres se describió a sí mismas como "completamente recuperadas," un tercio de ellas estaba experimentando un deterioro significativo y 17% fueron readmitidas bajo el cuidado de paciente interno. Los más pobres puntajes de GAF se asociaron con un diagnóstico clínico de trastornos de personalidad comórbidos, presencia antenatal de la enfermedad en el índice, uso ilícito de sustancias por parte de la pareja, percepción maternal de su unión afectiva, despego social del infante, así como la preocupación por la protección del infante. Después de que se les diera de alta, los resultados de la relación entre madre e infante fueron preocupantes. Sólo el 17% fue considerado adecuado. Se observaron mejoras a lo largo de este período en 56% pero el deterioro de la relación ocurrió en el 35%. El resultado materno y el de relación fueron asociados débilmente al momento de darles de alta (r2+0.29. p = 0.07) pero esto se perdió posteriormente al momento en que se les dio de alta. La relación compartida y la salud mental del infante deben ambas ser metas de intervención; ambas durante la admisión a la Unidad de Madres y Bebés y con posterioridad al momento en que se les da de alta.
Les recherches sur l'Unité psychiatrique Maman Bébé (en anglais Mother Baby Unit) ont porté sur la psychopathologie maternelle au cours d'une admission. On sait moins de choses sur le bien-être du bébé, leur relation ou la récupération en cours de la mère. Dans un échantillon initial de 45 femmes, nous décrivons des résultats à la sortie pour la psychopathologie maternelle (en utilisant le rapport maternel et l'Evaluation Globale de Fonction, soit GAF pour Global Assessment of Function en anglais) et la relation mère-bébé (en utilisant l'Index Expérimental Relationnel Enfant et Adulte, soir CARE Index, pour Child and Adult Relational Experimental Index en anglais). Trois mois après la sortie, un tiers des mères se décrivaient comme "ayant totalement récupéré", un tiers faisaient l'expérience d'une détérioration importante et 17% étaient réadmises en soins hospitaliers. Des scores GAF moins élevés étaient liés à un diagnostic clinique de trouble de la personnalité comorbide, à une présence anténatale de la maladie index, à une toxicomanie illicite du partenaire, à une perception maternelle de son lien, au retrait social du bébé et à des inquiétudes pour la protection de l'enfant. Après la sortie les résultats de la relation mère-bébé étaient inquiétants. Seuls 17% des résultats ont été considérés comme étant adéquats. Une amélioration a été observée durant cette période chez 56% mais une détérioration relationnelle a eu lieu pour 35%. Les résultats maternels et relationnels étaient faiblement corrélés à la sortie (r² = 0s29, p = 0,07) mais cela s'est avéré perdu après la sortie (r² = 0,03, p = 0,89). La relation partagée et la santé mentale du bébé devraient être tous deux des cibles d'intervention; à la fois durant l'admission dans l'Unité Maman Bébé et aussi après la sortie. Mots clés: bébé, après la sortie, unité maman bébé, santé mentale périnatale, relation mère-bébé.

OBJECTIVE: The 2012 European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guideline for diagnosis of celiac disease (CD) questioned the requirement for intestinal biopsy to confirm the diagnosis. The guideline recommends that in symptomatic patients with consistent human leukocyte antigen (HLA) subtypes, the diagnostic accuracy of strongly positive serology is sufficient to confirm the diagnosis. We prospectively assessed these guidelines in a "real-life" clinical setting. METHODS: One hundred and four children referred for evaluation of possible CD were prospectively recruited. Following informed consent, blood was drawn for serological testing and HLA analysis at upper gastrointestinal endoscopy. Histological findings according to Marsh criteria were correlated with blood results and the accuracy of the guideline analyzed.The study also examined the role of deamidated gliadin peptide (DGP) in the diagnosis of CD. RESULTS: For symptomatic patients with consistent HLA subtypes, strongly positive serology (as described in the ESPGHAN guidelines) accurately predicted biopsy-proven CD in >95% of cases. DGP was positive in fewer patients than anti-TG2 or EMA. Incorporation of DGP as a second confirmatory serological test in place of EMA was associated with maintained predictive value of guideline, but fewer patients fulfilling criteria for biopsy-free diagnosis. CONCLUSIONS: The ESPGHAN guideline performs well in our population. Adoption of the guideline would reduce the number of patients requiring endoscopy without compromise in diagnostic accuracy. The involvement of pediatric gastroenterological expertise, however, remains key to diagnosis of CD.

BACKGROUND: Infectious diseases are the leading cause of hospital admissions in young children. Hospitalisation with an infectious disease is a recurrent event for some children. Our objective was to describe risk factors for infectious disease readmission following hospital admission with an infectious disease in the first two years of life. METHODS: We performed a national cohort study of New Zealand children, born 2005-2009, with an infectious disease admission before age 24 months. Children readmitted with an infectious disease within 12 months of the first infectious disease admission were identified. Every infectious disease admission was categorised as a respiratory, enteric, skin and soft tissue, urinary or other infection. Independent associations of demographic and child health factors with infectious disease readmission were determined using multiple variable logistic regression. RESULTS: From 2005 to 2011, there were 69,902 infectious disease admissions for 46,657 children less than two years old. Of these 46,657 children, 10,205 (22%) had at least one infectious disease readmission within 12 months of their first admission. The first infectious disease admission was respiratory (54%), enteric (15%), skin or soft tissue (7%), urinary (4%) or other (20%). Risk of infectious disease readmission was increased if the first infectious disease admission was respiratory (OR = 1.87, 95% CI 1.78-1.95) but not if it was in any other infectious disease category. Risk factors for respiratory infectious disease readmission were male gender, Pacific or Maori ethnicity, greater household deprivation, presence of a complex chronic condition, or a first respiratory infectious disease admission during autumn or of ≥3 days duration. Fewer factors (younger age, male gender, presence of a complex chronic condition) were associated with enteric infection readmission. The presence of a complex chronic condition was the only factor associated with urinary tract infection readmission and none of the factors were associated with skin or soft tissue infection readmission. CONCLUSIONS: In children less than two years old, infectious disease readmission risk is increased if the first infectious disease admission is a respiratory infectious disease but not if it is another infectious disease category. Risk factors for respiratory infectious disease readmission are different from those for other infectious disease readmissions.

AIM: It is important to understand whether type 2 diabetes mellitus (T2DM) is increasing in childhood for health-care planning and clinical management. The aim of this study is to examine the incidence of T2DM in New Zealand children, aged <15 years from a paediatric diabetes centre, Auckland, New Zealand. METHODS: Retrospective analysis of prospectively collected data from a population-based referral cohort from 1995 to 2015. RESULTS: Hundred and four children presented with T2DM over the 21-year period. The female:male ratio was 1.8:1, at mean (standard deviation) age 12.9 (1.9) years, body mass index standard deviation score +2.3 (0.5), blood sugar 15.3 (8.5) mmol/L, HbA1c 76 (28) mmol/mol. At diagnosis, 90% had acanthosis nigricans and 48% were symptomatic. In all, 33% were Maori, 46% Pacific Island, 15% Asian/Middle Eastern and 6% European. There was a progressive secular increase of 5% year on year in incidence. The overall annual incidence of T2DM <15 years of age was 1.5/100â000 (1.2-1.9) (95% confidence interval), with higher rates in Pacific Island (5.9/100 000) and Maori (4.1/100 000). CONCLUSIONS: The incidence of T2DM in children <15 years of age in New Zealand has increased progressively at 5%/year over the last 21 years. The risk was disproportionately associated with girls and children from high-risk ethnic groups.

AIM: To review indications and use of angiotensin-converting enzyme-inhibitor (ACEI) therapy for the treatment of persistent microalbuminuria (MA) and/or hypertension (HTN) in adolescents with type 1 diabetes mellitus (T1DM). METHODS: Retrospective chart review of adolescent patients with T1DM seen within the paediatric diabetes service in Auckland, New Zealand, from 2006 to 2016. MA, HTN, patient demographic characteristics and ACEI prescribing and monitoring indices were examined. RESULTS: Five hundred adolescents with T1DM were included. There were 26 patients (5%) with MA and/or HTN. MA alone was present in 16, HTN alone in 3 and both HTN and MA in 7. The 5-year MA/HTN-free rate was 98%, and the 10-year MA/HTN-free rate was 93%. Longer disease duration and earlier diagnosis were predictors of MA/HTN. There was no significant difference in standard clinical indices between study patients and others. ACEI was prescribed for 17 of 26 patients for either HTN or MA. Within 6 weeks of ACEI commencement, less than half of the subjects had repeat serum creatinine and MA screens and no record of repeat blood pressure measurement. Despite this, all patients had 3-monthly reviews within outpatient clinics where adjustments of ACEI doses were made. CONCLUSION: In our regional adolescent population with T1DM, there were low rates of both MA and/or HTN. In those who required treatment with ACEI, clinical monitoring post-commencement of therapy was inconsistent. Local consensus guidelines for the management of persistent MA in children and adolescents with diabetes mellitus were developed in response to this study.

BACKGROUND: Bioequivalence between Tacrolimus Prograf® and generic tacrolimus formulations has been demonstrated in adult populations, however clinical experience and safety data regarding generic tacrolimus in pediatric transplant recipients is limited. This study aimed to evaluate conversion from Tacrolimus Prograf® to Sandoz® in pediatric renal transplant recipients nationwide. The primary outcome was a change in mean trough tacrolimus concentration. Additionally, changes in tacrolimus intra-patient coefficient of variation (CoV), allograft function, requirement for dose adjustments, and episodes of biopsy-proven rejection were evaluated. METHODS: Retrospective cohort study in 37 pediatric renal transplant recipients who switched to Tacrolimus Sandoz®. Each patient had three pre-conversion tacrolimus trough and creatinine concentrations within the 4 months prior and three post-conversion concentrations on day 3, 10, and the next subsequent level. Mean pre- and post-conversion tacrolimus trough concentrations and glomerular filtration rate (eGFR) were calculated. Tacrolimus concentration, CoV, and creatinine differences were compared by paired t test. RESULTS: Thirty-seven patients (41% females, age 3-18 years) were included. Average intra-patient difference in trough tacrolimus concentration was 0.05µg/l (95% CI -0.37 to 0.47). Average intra-patient difference in eGFR was -1.20 ml/min/1.732 (95% CI -3.53 to 1.13). Three patients had acute rejection during 12 months post-conversion compared to none during 12 months pre-conversion. CONCLUSIONS: Pediatric renal transplant recipients can be converted from Tacrolimus Prograf® to Sandoz® with negligible change in trough concentration, dose adjustments, or immediate allograft function. Of concern was the number of acute rejection episodes, however non-adherence contributed to at least one episode and this difference was determined clinically and statistically not significant.

AIM: To investigate the incidence and severity of anti-N-methyl-d-aspartate (anti-NMDA) receptor encephalitis in children from New Zealand. METHOD: A retrospective case series was undertaken of all children (≤18y) diagnosed with anti-NMDA receptor encephalitis from January 2008 to October 2015. RESULTS: Sixteen patients were identified with anti-NMDA receptor antibodies in the cerebrospinal fluid, three of whom had an associated teratoma. Fifteen children had Maori and/or Pacific Island ancestry. The incidence of anti-NMDA receptor encephalitis in Maori children was 3.4 per million children per year (95% confidence interval [CI] 1.4-7.0) and the incidence in Pacific children was 10.0 per million children per year (95% CI 4.3-19.8) compared with 0.2 per million children per year (95% CI 0.0-1.0) in children without Maori or Pacific Island ancestry. Sixty-seven per cent of children had a good outcome (modified Rankin Score ≤2) at 2 years' follow-up. This compares unfavourably with other cohorts despite a shorter median time to first-line immunotherapy (13d; range 4-89) and a higher proportion of children being treated with second-line therapy (50%). INTERPRETATION: Maori and Pacific Island children have a higher incidence of anti-NMDA receptor encephalitis and possibly a more severe phenotype. These data suggest a genetic predisposition to anti-NMDA receptor encephalitis in these populations.

Very long chain acyl-CoA dehydrogenase deficiency (VLCADD, OMIM #201475) has been increasingly diagnosed since the advent of expanded newborn screening (NBS). Elevated levels of tetradecenoyl-L-carnitine (C14:1) in newborn screening blood spot samples are particularly common in New Zealand, however this has not translated into increased VLCADD clinical presentations. A high proportion of screen-positive cases in NZ are of Maori or Pacific ethnicity and positive for the c.1226C > T (p.Thr409Met) ACADVL gene variant. We performed a retrospective, blinded, case-control study of 255 cases, born between 2006 and 2013, with elevated NBS C14:1 levels between 0.9 and 2.4 µmol/L, below the NZ C14:1 notification cut-off of 2.5 µmol/L. Coded healthcare records were audited for cases and age- and ethnicity- matched controls. The clinical records of those with possible VLCADD-related symptoms were reviewed. The follow-up period was 6 months to 7 years. Two of 247 cases (0.8 %) had possible VLCADD-like symptoms while four of 247 controls (2 %) had VLCADD-like symptoms (p = 0.81). Maori were overrepresented (68 % of the cohort vs 15 % of population). Targeted analysis of the c.1226 locus revealed the local increase in screening C14:1 levels is associated with the c.1226C > T variant (97/152 alleles tested), found predominantly in Maori and Pacific people. There was no increase in clinically significant childhood disease, irrespective of ethnicity. The study suggests that children with elevated C14:1, between 0.9-2.4 µmol/L, on NBS are at very low risk of clinically significant childhood disease. A minimally interventional approach to managing these patients is indicated, at least in the New Zealand population.

BACKGROUND: Anemia is a major complication for patients on chronic dialysis. Erythropoietin is effective if iron is available, however unnecessary iron supplementation results in iron overload. Reticulocyte hemoglobin equivalent (Ret-He) may be useful for assessing iron status. METHODS: A national retrospective cohort study including all children on chronic dialysis in New Zealand between 2007 and 2013, pairing Ret-He with demographic information, anemia indices, and markers of iron status. RESULTS: In 606 observations, we found a modest relationship between Ret-He and transferrin saturation (TSAT) (r = 0.34, p < 0.001) and a poor correlation between Ret-He and ferritin (r = 0.09, p = 0.04). There was a negative correlation between ferritin and hemoglobin (r = -0.14, p = 0.002), a weak positive correlation between TSAT and hemoglobin (r = 0.12, p = 0.007), and a modest positive correlation between Ret-He and hemoglobin (r = 0.22, p < 0.001). The diagnostic performance of Ret-He to detect absolute iron deficiency (cut-off value 28.9 pg, sensitivity 90 %, specificity 75 %, AUC 0.87) was good. CONCLUSIONS: Ret-He is a more relevant marker of iron status than ferritin and TSAT. This supports prospectively testing Ret-He to distinguish between iron deficiency and suboptimal erythropoietin dosing as competing causes for anemia. Ferritin is an unhelpful biomarker of iron deficiency in this setting.

BACKGROUND: Intravenous cannulation is a painful procedure that can provoke anxiety and stress. Injecting local anaesthetic can provide analgesia at the time of cannulation, but it is a painful procedure. Topical anaesthetic creams take between 30 and 90 minutes to produce an effect. A quicker acting analgesic allows more timely investigation and treatment. Vapocoolants have been used in this setting, but studies have reported mixed results. OBJECTIVES: To determine effects of vapocoolants on pain associated with intravenous cannulation in adults and children. To explore variables that might affect the performance of vapocoolants, including time required for application, distance from the skin when applied and time to cannulation. To look at adverse effects associated with the use of vapocoolants. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Latin American Caribbean Health Sciences Literature (LILACS), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Institute for Scientific Information (ISI) Web of Science and the http://clinicaltrials.gov/, http://www.controlled-trials.com/ and http://www.trialscentral.org/ databases to 1 May 2015. We applied no language restrictions. We also scanned the reference lists of included papers. SELECTION CRITERIA: We included all blinded and unblinded randomized controlled trials (RTCs) comparing any vapocoolant with placebo or control to reduce pain during intravenous cannulation in adults and children. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trial quality and extracted data, contacted study authors for additional information and assessed included studies for risk of bias. We collected and analysed data for the primary outcome of pain during cannulation, and for the secondary outcomes of pain associated with application of the vapocoolant, first attempt success rate of intravenous cannulation, adverse events and participant satisfaction. We performed subgroup analyses for the primary outcome to examine differences based on age of participant, type of vapocoolant used, application time of vapocoolant and clinical situation (emergency vs elective). We used random-effects model meta-analysis in RevMan 5.3 and assessed heterogeneity between trial results by examining forest plots and calculating the I(2) statistic. MAIN RESULTS: We found nine suitable studies of 1070 participants and included them in the qualitative analyses. We included eight studies of 848 participants in the meta-analysis for the primary outcome (pain during intravenous cannulation). Use of vapocoolants resulted in a reduction in pain scores as measured by a linear 100 mm visual analogue scale (VAS 100) compared with controls (difference between means -12.5 mm, 95% confidence interval (CI) -18.7 to -6.4 mm; moderate-quality evidence). We could not include in the meta-analysis one study, which showed no effects of the intervention.Use of vapocoolants resulted in increased pain scores at the time of application as measured by a VAS 100 compared with controls (difference between means 6.3 mm, 95% CI 2.2 to 10.3 mm; four studies, 461 participants; high-quality evidence) and led to no difference in first attempt success compared with controls (risk ratio (RR) 1.00, 95% CI 0.94 to 1.06; six studies, 812 participants; moderate-quality evidence). We documented eight minor adverse events reported in 279 vapocoolant participants (risk difference (RD) 0.03, 95% CI 0 to 0.05; five studies, 551 participants; low quality-evidence).The overall risk of bias of individual studies ranged from low to high, with high risk of bias for performance and detection bias in four studies. Sensitivity analysis showed that exclusion of studies at high or unclear risk of bias did not materially alter the results of this review. AUTHORS' CONCLUSIONS: Moderate-quality evidence indicates that use of a vapocoolant immediately before intravenous cannulation reduces pain during the procedure. Use of vapocoolant does not increase the difficulty of cannulation nor cause serious adverse effects but is associated with mild discomfort during application.

OBJECTIVES: Centralization of PICUs requires a transport system that delivers patient outcomes equivalent to that of the same institution admissions. Our aim was to evaluate how pediatric critical care retrieval, distance traveled, and referral center level of ICU support impact on outcomes in unplanned admissions. DESIGN: Retrospective cohort study. SETTING: The national PICU in New Zealand. PATIENTS: A total of 5,609 (45% retrieved) unplanned pediatric admissions (< 15 yr) between January 1, 2004, and January 1, 2014. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data analyzed included case-mix, source of admission, diagnostic category, Pediatric Index of Mortality score, PICU-specific resource use, distance traveled, transport duration, and referral hospital ICU level. Outcome measures were crude and risk-adjusted PICU mortality and PICU length of stay. Compared with nontransported admissions, retrieved children were younger, more frequently admitted outside normal working hours, had higher predicted mortality (median Pediatric Index of Mortality score, 4.7% vs 1.5%; p < 0.001) and PICU-specific resource use (respiratory support, vasoactive infusions, and renal replacement therapy). The transport cohort had greater crude mortality rates (8.6% vs 5.6%; p < 0.008) and a median of 29 hours longer PICU stay. There was no significant difference in risk-adjusted mortality between the cohorts (observed/expected mortality ratio for retrieved patients, 0.84 vs nontransported patients, 0.91; p = 0.73). Neither distance traveled (median, 135 km), transport duration (median, 4.4 hr), nor the level of ICU at the referral center had a significant effect on risk-adjusted PICU mortality in the retrieved cohort. CONCLUSIONS: Children retrieved to the national PICU in New Zealand have greater predicted mortality risk and PICU-specific resource use than nontransported patients. There is no significant difference in risk-adjusted mortality between retrieved and the same institution admissions. Critically ill pediatric patients can be transported long distances by specially trained and equipped transport teams, without an increase in risk-adjusted PICU mortality.

BACKGROUND: The term severe acute respiratory infection (SARI) encompasses a heterogeneous group of respiratory illnesses. Grading the severity of SARI is currently reliant on indirect disease severity measures such as respiratory and heart rate, and the need for oxygen or intensive care. With the lungs being the primary organ system involved in SARI, chest radiographs (CXRs) are potentially useful for describing disease severity. Our objective was to develop and validate a SARI CXR severity scoring system. METHODS: We completed validation within an active SARI surveillance project, with SARI defined using the World Health Organization case definition of an acute respiratory infection with a history of fever, or measured fever of ≥ 38 °C; and cough; and with onset within the last 10 days; and requiring hospital admission. We randomly selected 250 SARI cases. Admission CXR findings were categorized as: 1 = normal; 2 = patchy atelectasis and/or hyperinflation and/or bronchial wall thickening; 3 = focal consolidation; 4 = multifocal consolidation; and 5 = diffuse alveolar changes. Initially, four radiologists scored CXRs independently. Subsequently, a pediatrician, physician, two residents, two medical students, and a research nurse independently scored CXR reports. Inter-observer reliability was determined using a weighted Kappa (κ) for comparisons between radiologists; radiologists and clinicians; and clinicians. Agreement was defined as moderate (κ > 0.4-0.6), good (κ > 0.6-0.8) and very good (κ > 0.8-1.0). RESULTS: Agreement between the two pediatric radiologists was very good (κ = 0.83, 95% CI 0.65-1.00) and between the two adult radiologists was good (κ = 0.75, 95% CI 0.57-0. 93). Agreement of the clinicians with the radiologists was moderate-to-good (pediatrician:κ = 0.65; pediatric resident:κ = 0.69; physician:κ = 0.68; resident:κ = 0.67; research nurse:κ = 0.49, medical students: κ = 0.53 and κ = 0.56). Agreement between clinicians was good-to-very good (pediatrician vs. physician:κ = 0.85; vs. pediatric resident:κ = 0.81; vs. medicine resident:κ = 0.76; vs. research nurse:κ = 0.75; vs. medical students:κ = 0.63 and 0.66). Following review of discrepant CXR report scores by clinician pairs, κ values for radiologist-clinician agreement ranged from 0.59 to 0.70 and for clinician-clinician agreement from 0.97 to 0.99. CONCLUSIONS: This five-point CXR scoring tool, suitable for use in poorly- and well-resourced settings and by clinicians of varying experience levels, reliably describes SARI severity. The resulting numerical data enables epidemiological comparisons of SARI severity between different countries and settings.

The creation of the Central Laboratory immediately after the United Alkali Company (UAC) was formed in 1890, by amalgamating the Leblanc alkali works in Britain, brought high expectations of repositioning the company by replacing its obsolete Leblanc process plant and expanding its range of chemical products. By 1914, UAC had struggled with few exceptions to adopt new technologies and processes and was still reliant on the Leblanc process. From 1914, the Government would rely heavily on its contribution to the war effort. As a major heavy-chemical manufacturer, UAC produced chemicals for explosives and warfare gases, while also trying to maintain production of many essential chemicals including fertilisers for homeland consumption. UAC's wartime effort was led by the Central Laboratory, working closely with the recently established Engineer's Department to develop new process pathways, build new plant, adapt existing plant, and produce the contracted quantities, all as quickly as possible to meet the changing battlefield demands. This article explores how wartime conditions and demands provided the stimulus for the Central Laboratory's crucial R&D work during World War One.

BACKGROUND: Abnormalities on magnetic resonance imaging scans are common both before and after surgery for congenital heart disease in early infancy. The aim of this study was to prospectively investigate the nature, timing, and consequences of brain injury on magnetic resonance imaging in a cohort of young infants undergoing surgery for congenital heart disease both with and without cardiopulmonary bypass. METHODS AND RESULTS: A total of 153 infants undergoing surgery for congenital heart disease at <8 weeks of age underwent serial magnetic resonance imaging scans before and after surgery and at 3 months of age, as well as neurodevelopmental assessment at 2 years of age. White matter injury (WMI) was the commonest type of injury both before and after surgery. It occurred in 20% of infants before surgery and was associated with a less mature brain. New WMI after surgery was present in 44% of infants and at similar rates after surgery with or without cardiopulmonary bypass. The most important association was diagnostic group (P<0.001). In infants having arch reconstruction, the use and duration of circulatory arrest were significantly associated with new WMI. New WMI was also associated with the duration of cardiopulmonary bypass, postoperative lactate level, brain maturity, and WMI before surgery. Brain immaturity but not brain injury was associated with impaired neurodevelopment at 2 years of age. CONCLUSIONS: New WMI is common after surgery for congenital heart disease and occurs at the same rate in infants undergoing surgery with and without cardiopulmonary bypass. New WMI is associated with diagnostic group and, in infants undergoing arch surgery, the use of circulatory arrest.

AIM: A nationwide 24-month study was conducted (2007-2009), via the New Zealand Paediatric Surveillance Unit to define epidemiology and clinical features of acute poststreptococcal glomerulonephritis (APSGN) in children hospitalised with the illness. METHODS: Paediatricians (n = 215) were requested to report new hospitalised cases fulfilling a case definition of definite (haematuria with low C3 and high streptococcal titres or biopsy proven APSGN) or probable (haematuria with low C3 or high streptococcal titres). RESULTS: A total of 176 cases were identified (definite: n = 138, probable: n = 38) with 63% residing in the Auckland metropolitan region. Sixty-seven percent were in the most deprived quintile. Annual incidence (0-14 years) was 9.7/100,000 (Pacific 45.5, Maori 15.7, European/other 2.6 and Asian 2.1/100,000). Annual incidence was highest in the South Auckland Metropolitan region (31/100,000), Central Auckland 14.9, West/North Auckland metropolitan region 5.9 and for the remainder of New Zealand 5.5/100,000. Age-specific incidence was highest in age 5-9 years (15.1/100,000). Reduced serum complement C3, gross haematuria, hypertension, impairment of renal function and heavy proteinuria were present in 93%, 87%, 72%, 67% and 44% of patients, respectively. Severe hypertension was closely associated with either symptoms of an acute encephalopathy or congestive heart failure. CONCLUSIONS: New Zealand children carry a significant disease burden of hospitalised APSGN with socio-economically deprived; Pacific and Maori children are being over-represented. Significant short-term complications were observed in hospitalised children with APSGN. Persistently very low rates in European/other suggest a preventable disease.

AIM: School-based interventions to tackle the rise in childhood overweight and obesity remain inconclusive and are often limited in their application to diverse populations. To inform and measure the effect of the implementation of a primary school-based longitudinal randomised controlled nutrition and activity intervention, Project Energize, baseline measures of body size and blood pressure were required. METHODS: This cross-sectional study stratified by age, sex, ethnicity, rurality and school socio-economic-status (school-SES) measured body mass index (BMI), percentage body fat (%BF), waist and resting blood pressure from 2752 5- and 10-year-old children (62% European, 31% Maori) representative of the Waikato region of New Zealand. RESULT: Waikato children have a high prevalence of overweight and obesity that is linked with hypertension. Cardiovascular risk factors including raised blood pressure and hypertension, waist and arm circumference and percentage body fat (%BF) were more prevalent in 10-year-olds, lower school-SES and to some extent, urban living. In European children, BMI and waist circumference were similarly predictive of %BF, but for Maori children, waist circumference predicted %BF better than BMI. CONCLUSIONS: A variety of stratified, baseline measurements is important when designing school-based interventions. In particular, waist circumference measures may be a more accurate predictor of %BF than BMI when determining measurement protocols that consider different ethnic groups and environments among children. The effect of targeted improvements of the school physical activity and nutrition environment on the rate of increase of weight, fatness and blood pressure in children should be examined.

BACKGROUND: Patient-centered innovation is spreading at the federal and state levels. A conceptual framework can help frame real-world examples and extract systematic learning from an array of innovative applications currently underway. The statutory, economic, and political environment in Washington State offers a special contextual laboratory for observing the interplay of these factors. PURPOSE: We propose a framework for understanding the process of initiating patient-centered innovations-particularly innovations addressing patient-centered goals of improved access, continuity, communication and coordination, cultural competency, and family- and person-focused care over time. The framework to a case study of a provider organization in Washington State actively engaged in such innovations was applied in this article. METHODS: We conducted a selective review of peer-reviewed evidence and theory regarding determinants of organizational change. On the basis of the literature review and the particular examples of patient-centric innovation, we developed a conceptual framework. Semistructured key informant interviews were conducted to illustrate the framework with concrete examples of patient-centered innovation. FINDINGS: The primary determinants of initiating patient-centered innovation are (a) effective leadership, with the necessary technical and professional expertise and creative skills; (b) strong internal and external motivation to change; (c) clear and internally consistent organizational mission; (d) aligned organizational strategy; (e) robust organizational capability; and (f) continuous feedback and organizational learning. The internal hierarchy of actors is important in shaping patient-centered innovation. External financial incentives and government regulations also significantly shape innovation. PRACTICE IMPLICATIONS: Patient-centered care innovation is a complex process. A general framework that could help managers and executives organize their thoughts around innovation within their organization is presented.

This article explores George Davis's editing of the Chemical Trades Journal (CTJ) between 1887 and 1906, a period during which he was also working as a consultant chemist and consultant chemical engineer. Davis had worked from 1870 in various sectors of the chemical industry before becoming a sub-inspector in the Alkali Inspectorate between 1878 and 1884. It was during this period that the British chemical industry was facing severe economic pressure and to remain competitive was having to adapt to less wasteful and more efficient production. Drawing on this wide industrial experience, Davis developed a framework for chemical engineering with the broad aim of making chemical manufacture as economic as the latest science and technology would allow. Several important issues are raised by Davis's editorship of the weekly CTJ alongside his extensive consultancy work and other responsibilities: Davis's motivation given the likely impact on his consultancy work; the community the CTJ hoped to serve; competitive periodicals addressing the same market niche; the degree of focus on his chemical engineering framework; the changing content of the CTJ; and Davis's role as editor over a period of nearly twenty years.
RESUMEN
OBJECTIVES: To assess the validity of an International Classification of Diseases (ICD) code based definition of non-fatal head trauma caused by child abuse (abusive head trauma) for population surveillance in New Zealand. DESIGN: A retrospective cohort study of hospital inpatient records. SETTING: A tertiary children's hospital in Auckland, New Zealand. PARTICIPANTS: 1731 children less than 5 years of age who were discharged after a non-fatal head trauma event over a 10-year period from 1 January 2010 to 31 December 2019. OUTCOME MEASURES: The outcome of assessment by the hospital's multidisciplinary child protection team (CPT) was compared with the outcome of ICD, Tenth Revision (ICD-10) discharge coding for non-fatal abusive head trauma (AHT). The ICD-10 code definition of AHT was derived from an ICD, Ninth Revision, Clinical Modification definition developed by the Centers for Disease Control, Atlanta, Georgia, which requires both a clinical diagnosis code and a cause-of-injury code. RESULTS: There were 1755 head trauma events with 117 determined as AHT by the CPT. The ICD-10 code definition had a sensitivity of 66.7% (95% CI 57.4 to 75.1) and specificity of 99.8% (95% CI 99.5 to 100). There were only three false positives but 39 false negatives, with 18 of the false negatives coded with X59 (exposure to unspecified factor). CONCLUSIONS: The ICD-10 code broad definition of AHT is a reasonable epidemiological tool for passive surveillance of AHT in New Zealand but it underestimates the incidence. Its performance could be improved by clear documentation of child protection conclusions in clinical notes, clarifying coding practice and removing the exclusion criteria from the definition.
