Sepsis is defined as dysregulated host response to infection that leads to life-threatening organ dysfunction. Biomarkers characterising the dysregulated host response in sepsis are lacking. We aimed to develop host gene expression signatures to predict organ dysfunction in children with bacterial or viral infection.

Toe and foot swelling can manifest as lymphoedema or chronic oedema but can also be a complication of the treatment of these conditions. In this article, the authors discuss the assessment and treatment options for toe and foot swelling, highlighting the importance of prevention in the first instance.

Background:There is no clear guidance or comprehensive comparative evidence to help clinicians select between adjustable wraps for compression therapy. However, adjustable wraps could be compared with three metrics used for compression bandages: variation in pressure, stiffness and elasticity.Aims:To determine whether easywrap (Haddenham Healthcare) had lower standard deviation (SD) in lying pressure, greater static stiffness index (SSI) and/or a greater mean elongation ratio than six other adjustable wraps.Methods:In this preliminary exploratory study, seven adjustable wraps were tested in vivo 20 times each (140 tests in total), on 20 people (with a variable number of readings per participant), to give the SD in lying pressure and mean SSI. The same wraps were tested in vitro five times each to give the mean elongation ratio.Findings:Of all seven adjustable wraps, easywrap had the second lowest SD in lying pressure at 5.9 mmHg, compared with 8.9 mmHg overall; the highest mean SSI at 13.2 mmHg, compared with 9.5 mmHg overall; and the highest mean elongation ratio at 137.0%, compared with 107.1% overall.Conclusions:These metrics suggest that easywrap has clinical advantages over other adjustable wraps. A lower variation in lying pressure suggests more consistent application of pressures within intended therapeutic levels. Higher SSI indicates greater resistance to stretching, which is linked to improved venous function and oedema reduction. Higher elongation ratio demonstrates greater tensile strength, which should maintain therapeutic pressure for longer without readjustment.

The objective of this review was to evaluate attention and executive function performance in children with neurodevelopmental conditions across the first 5 years of life, compared to neurotypical peers. MEDLINE, EMBASE, and PsycINFO databases were searched until June 30, 2023, and studies comparing attention or executive function between children with (or at risk for) neurodevelopmental conditions and neurotypical (or low risk) peers, 0 to 5 years old, were included. Of the 4338 studies identified, 111 studies with 12292 participants were included in the meta-analysis. The qualitative analysis of brain development included 5 studies. Primary outcomes were the standardised mean difference (Hedges’ g) in attention and executive function between groups. Meta-regressions examined moderating effects of age, biological sex, diagnosis, and measure type. Children with neurodevelopmental conditions showed small delays in attention (n= 49 studies, k= 251 outcomes, g= 0.36, 95% CI 0.23-0.48, p< 0.001) and moderate delays in executive function (n= 64 studies, k= 368 outcomes, g= 0.64,95% CI 0.53–0.76, p< 0.001). Attention and executive function delays could not be identified in the first year (equivalence tests, p< 0.001), small to moderate delays were found in toddlerhood and moderate delays by preschool. Delays identified were largely transdiagnostic, although there was some evidence of diagnosis-specific delays for attention and moderation by measure type (informant rating vs performance-based vs physiological). Qualitative analysis described how delays were underpinned by a divergence of brain development in medial prefrontal regions. These findings highlight the potential of using attention and executive measures to detect delay and to intervene in neurodevelopmental conditions early in life.

To examine the clinical characteristics and short term outcomes for children with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infections who presented to Australian hospitals during 2020 and 2021. Retrospective case review study in nineteen hospitals of the Paediatric Research in Emergency Departments International Collaborative (PREDICT) network from all Australian states and territories, including seven major paediatric tertiary centres and eight Victorian hospitals. SARS‐CoV‐2‐positive people under 18 years of age who attended emergency departments or were admitted to hospital during 1 February 2020 – 31 December 2021. Epidemiological and clinical characteristics, by hospital care type (emergency department [ED] or inpatient care). A total of 1193 SARS‐CoV‐2‐positive children and adolescents (527 girls, 44%) attended the participating hospitals (107 in 2020, 1086 in 2021). Their median age was 3.8 years (interquartile range [IQR], 0.8–11.4 years); 63 were Aboriginal or Torres Strait Islander people (5%). Other medical conditions were recorded for 293 children (25%), including asthma (86, 7%) and premature birth (68, 6%). Medical interventions were not required during 795 of 1181 ED presentations (67%); children were discharged directly home in 764 cases (65%) and admitted to hospital in 282 (24%; sixteen to intensive care units). The 384 admissions to hospital (including 102 direct admissions) of 341 children (25 infants under one month of age) included 23 to intensive care (6%); the median length of stay was three days (IQR, 1–9 days). Medical interventions were not required during 261 admissions (68%); 44 children received respiratory support (11%) and 21 COVID‐19‐specific treatments, including antiviral and biologic agents (5%). Being under three months of age (vone year to less than six years: odds ratio [OR], 2.6; 95% confidence interval [CI], 1.7–4.0) and pre‐existing medical conditions (OR, 2.5; 95% CI, 1.9–3.2) were the major predictors of hospital admission. Two children died, including one without a known pre‐existing medical condition. During 2020 and 2021, most SARS‐CoV‐2‐positive children and adolescents who presented to participating hospitals could be managed as outpatients. Outcomes were generally good, including for those admitted to hospital.

There is robust evidence that sex (biological) and gender (behavioral/social) differences influence hearing loss risk and outcomes. These differences are noted for animals and humans—in the occurrence of hearing loss, hearing loss progression, and response to interventions. Nevertheless, many studies have not reported or disaggregated data by sex or gender. This article describes the influence of sex-linked biology (specifically sex-linked hormones) and gender on hearing and hearing interventions, including the role of sex-linked biology and gender in modifying the association between risk factors and hearing loss, and the effects of hearing loss on quality of life and functioning. Most prevalence studies indicate that hearing loss begins earlier and is more common and severe among men than women. Intrinsic sex-linked biological differences in the auditory system may account, in part, for the predominance of hearing loss in males. Sex- and gender-related differences in the effects of noise exposure or cardiovascular disease on the auditory system may help explain some of these differences in the prevalence of hearing loss. Further still, differences in hearing aid use and uptake, and the effects of hearing loss on health may also vary by sex and gender. Recognizing that sex-linked biology and gender are key determinants of hearing health, the present review concludes by emphasizing the importance of a well-developed research platform that proactively measures and assesses sex- and gender-related differences in hearing, including in understudied populations. Such research focus is necessary to advance the field of hearing science and benefit all members of society.

BackgroundHead injury is a common reason children present to EDs. Guideline development to improve care for paediatric head injuries should target the information needs of ED clinicians and factors influencing its uptake.MethodsWe conducted semi-structured qualitative interviews (November 2017–November 2018) with a stratified purposive sample of ED clinicians from across Australia and New Zealand. We identified clinician information needs, used the Theoretical Domains Framework (TDF) to explore factors influencing the use of head CT and clinical decision rules/guidelines in CT decision-making, and explored ways to improve guideline uptake. Two researchers coded the interview transcripts using thematic content analysis.ResultsA total of 43 clinicians (28 doctors, 15 nurses), from 19 hospitals (5 tertiary, 8 suburban, 6 regional/rural) were interviewed. Clinicians sought guidance for scenarios including ED management of infants, children with underlying medical issues, delayed or representations and potential non-accidental injuries. Improvements to the quality and content of discharge communication and parental discussion materials were suggested. Known risks of radiation from head CTs has led to a culture of observation over use of CT in Australasia (TDF domain: beliefs about consequences). Formal and informal policies have resulted in senior clinicians making most head CT decisions in children (TDF domain: behavioural regulation). Senior clinicians consider their gestalt to be more accurate and outperform existing guidance (TDF domain: beliefs about capabilities), although they perceive guidelines as useful for training and supporting junior staff. Summaries, flow charts, publication in ED-specific journals and scripted training materials were suggestions to improve uptake.ConclusionInformation needs of ED clinicians, factors influencing use of head CT in children with head injuries and the role of guidelines were identified. These findings informed the scope and implementation strategies for an Australasian guideline for mild-to-moderate head injuries in children.

Background: Hearing loss and mild behavioral impairment (MBI), both non-cognitive markers of dementia, can be early warning signs of incident cognitive decline.Objective: We investigated the relationship between these markers and reported the influence of sex, using non-dementia participants (n?=?219; 107 females) from the Canadian Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND).Methods: Hearing was assessed with the 10-item Hearing Handicap for the Elderly–Screening (HHIE-S) questionnaire, a speech-in-noise test, screening audiometry, and hearing aid use. MBI symptoms were assessed using the Neuropsychiatric Inventory Questionnaire (NPI-Q). Multivariable linear regressions examined the association between hearing and MBI symptom severity and multiple logistic regressions examined the association between hearing and MBI domains.Results: HHIE-S score was significantly associated with greater global MBI symptom burden, and symptoms in the apathy and affective dysregulation domains. Objective measures of audiometric hearing loss and speech-in-noise testing as well as hearing aid use were not associated with global MBI symptom severity or the presence of MBI domain-specific symptoms. Males were older, had more audiometric and speech-in-noise hearing loss, higher rates of hearing-aid use, and showed more MBI symptoms than females, especially apathy.Conclusion: The HHIE-S, a subjective self-report measure that captures emotional and social aspects of hearing disability, was associated with informant-reported global MBI symptom burden, and more specifically the domains of affective dysregulation and apathy. These domains can be potential drivers of depression and social isolation. Hearing and behavior change can be assessed with non-invasive measures, adding value to a comprehensive dementia risk assessment.

AbstractVision and hearing impairments are highly prevalent in adults 65 years of age and older. There is a need to understand their association with multiple health-related outcomes. We analyzed data from the Resident Assessment Instrument for Home Care (RAI-HC). Home care clients were followed for up to 5 years and categorized into seven unique cohorts based on whether or not they developed new vision and/or hearing impairments. An absolute standardized difference (stdiff) of at least 0.2 was considered statistically meaningful. Most clients (at least 60%) were female and 34.9 per cent developed a new sensory impairment. Those with a new concurrent vison and hearing impairment were more likely than those with no sensory impairments to experience a deterioration in receptive communication (stdiff = 0.68) and in cognitive performance (stdiff = 0.49). After multivariate adjustment, they had a twofold increased odds (adjusted odds ratio [OR] = 2.1; 95% confidence interval [CI]:1,87, 2.35) of deterioration in cognitive performance. Changes in sensory functioning are common and have important effects on multiple health-related outcomes.

Montreal Cognitive Assessment (MoCA) is a method that can help the physicians assess the cognitive abilities of a person in a span of about 10 minutes. In the event, the physicians find mild cognitive impairment, they can take necessary measures to correct the situation. It may be noted that some studies have indicated that MCI could lead to dementia though it is a controversial matter.

The animal rights group, People for the Ethical Treatment to Animals (PETA) are carrying out a crusade against the Girl Scout group in Alaska because of a state-sponsored program where girls hunt for beavers, cook them and use the skin to make mittens and hats. PETA officials state that notwithstanding local customs, they are trying to strike a right balance in the region as such programs impart wrong values in children who do not view animals as living beings.

The Athabsacan tradition of snowshoe making in Alaska is under threat as the existing snowshoe makers age and die and nobody steps forward to fill their shoes. Bill Mackowski, an expert on Native-made snowshoes and their history, contends that the art form has died off quicker in Alaska than in Canada as Westernization has spread more quickly in Alaska over the past 100 years than it has in Canada.

During the course of the COVID-19 pandemic, lymphoedema and community clinicians have had to modify how they implement intensive treatments for patients with lymphoedema and chronic oedema. Using novel approaches to treat and move patients towards self-management regimes has enabled patients to be in control of their condition, particularly if they are unable to attend normal clinic appointments. This article explores how using Haddenham easywrap instead of time- and resource-intensive bandaging regimes, alongside the Haddenham LymphFlow Advance, as part of self-management programmes, can benefit patients' quality of life, reduce costs and resource use and enable patients to self-manage this long-term chronic condition more effectively.

The use of compression therapy to treat chronic oedema of the lower limbs can be a challenge, especially when this is undertaken by clinicians who have limited experience and knowledge of the theoretical principles which underpin its use in clinical practice. This articles aims to discuss the reasoning which underpins the use of compression hosiery in the management of lymphoedema and how this understanding can improve treatment outcomes and reduce the burden of disease on patients and clinical resources.

This paper describes the development of an improved and scalable method for the manufacture of nemiralisib, a phosphatidylinositol-3-kinase delta inhibitor. Incorporation of three consecutive catalytic reactions, including a palladium-catalyzed C–H functionalization and an iridium-catalyzed borylation, significantly simplified and shortened the synthetic sequence. The revised route was successfully implemented in a pilot plant on a multikilogram scale to deliver >100 kg of product.

ABSTRACTThe purpose of this study was to describe the prevalence of hearing loss (HL), vision loss (VL), and dual sensory loss (DSL) in Canadians 45–85 years of age. Audiometry and visual acuity were measured. Various levels of impairment severity were described. Results were extrapolated to the 2016 Canadian population. In 2016, 1,500,000 Canadian males 45–85 years of age had at least mild HL, 1,800,000 had at least mild VL, and 570,000 had DSL. Among females, 1,200,000 had at least mild HL, 2,200,000 had at least mild VL, and 450,000 had DSL. Among Canadians 45–85 years of age, mild, moderate, and severe HL was prevalent among 13.4 per cent, 3.7 per cent, and 0.4 per cent of males, and among 11.3 per cent, 2.3 per cent, and 0.2 per cent of females, respectively. Mild and moderate, or severe VL was prevalent among 19.8 per cent and 2.4 per cent of males, and among 23.9 per cent and 2.6 per cent of females, respectively. At least mild DSL was prevalent among 6.4 per cent of males and 6.1 per cent of females.

BackgroundClinical decision rules (CDRs) are commonly used to guide imaging decisions in cervical spine injury (CSI) assessment despite limited evidence for their use in paediatric populations. We set out to determine CSI incidence, imaging rates and the frequency of previously identified CSI risk factors, and thus assess the projected impact on imaging rates if CDRs were strictly applied as a rule in our population.MethodsA single-centre prospective observational study on all aged under 16 years presenting for assessment of possible CSI to a tertiary paediatric emergency department over a year, commencing September 2015. CDR variables from the National Emergency X-Radiography Utilization Study (NEXUS) rule, Canadian C-Spine rule (CCR) and proposed Paediatric Emergency Care Applied Research Network (PECARN) rule were collected prospectively and applied post hoc.Results1010 children were enrolled; 973 had not received prior imaging. Of these, 40.7% received cervical spine imaging; 32.4% X-rays, 13.4% CT scan and 3% MRI. All three CDRs identified the five children (0.5%) with CSI who had not received prior imaging. If CDRs were strictly applied as a rule for imaging, projected imaging rates in our setting would be as follows: NEXUS-44% (95% CI 41% to 47.4%), CCR-at least 48.4% (95% CI 45.3% to 51.7%) and PECARN-68% (95% CI 65.1% to 71.1%).ConclusionCSIs were rare (0.5% of our cohort), however, 40% of children received imaging. CDRs have been designed to guide imaging decisions; if strictly applied as a rule for imaging, the CDRs assessed in this study would increase imaging rates. Projected rates differ considerably depending on the CDR applied. These findings highlight the need for a validated paediatric-specific cervical spine imaging CDR.

AbstractThis applied experimental research tested the effectiveness of a universal, student-focused intervention (‘Memory Mates’), specifically focused on supporting students to use attention and working memory strategies within academic contexts, unlike computer-based programs. Memory Mates is presented in the form of icons and explanations, with the strategies embedded within the classroom. Analyses compared the impact of the intervention over 8 months in three schools with three control schools, comprising 13 Year 4 primary school classes. The intervention group students showed a significant improvement in mathematics and spelling; however, there was no differential effect on reading comprehension or academic engagement. Based on the present results, it is contended that implementing Memory Mates within classroom contexts demonstrated promising potential as a new approach to supporting academic progress.

ObjectiveTo evaluate the impact of fetal alcohol spectrum disorder (FASD) on child and family functioning.DesignProspective survey.SettingMultidisciplinary FASD assessment service.PatientsCaregivers of 35 children with FASD.Main outcome measuresChild-health-related functioning (Royal Alexandra Hospital for Children Measure of Function (MOF)), family impact (Impact on Family (IOF) Scale), impact on siblings and caregiver stress.ResultsMost caregivers were foster carers (74%). Children with FASD (median age 8.7 years; 54% male) were a median of 7.0 years at diagnosis. Regarding child-health-related functioning, 43% reported moderate, severe or major problems in at least one area on the MOF. IOF was moderate (60%) or high (34%). Poorer child-health-related functioning was associated with greater impact on family. Unaffected siblings received less parental attention and displayed anger or frustration about the affected child’s needs. Caregivers reported frequent and high levels of stress.ConclusionsFASD impacts children’s health, and function of the family and unaffected siblings. These novel findings highlight the need for family-oriented service development.

Over recent years, compression wraps, also known as adjustable compression wrapping devices (ACWDs), have become an increasingly important part of lymphoedema management. Widely used in lymphoedema clinics, they are also now a popular treatment choice within tissue viability, as well as in practice and community nursing, where their cost- and resource-saving advantages are greatly appreciated. Easywrap from Haddenham Healthcare is a popular choice among both health professionals and patients, due to its low profile, making it a comfortable option for wearing beneath normal clothes, and its uncomplicated design, making it easy for patients to put on and take off themselves. This article will evaluate the advantages of using Easywrap for self-management and explore why the Fusion liner, which is now available on drug tariff, can further improve self-care in lymphoedema management.

Compression therapy is the mainstay of treatment in venous and lymphatic diseases. Optimisation of compression therapy is not a new concept, but, in the UK, the use of 24-hour compression therapy as part of the maintenance phase of treatment has not been standard practice and, until recently, has only been adopted by certain specialist centres. One such modality in the process of optimisation is the use of products that are classed as ‘reduced compression’ or ‘night-time garments’. These are not traditional flat- or circular-knit garments but are made of various components to include foam and, more recently, knitted cotton fabrics. Haddenham Comfiwave is a new product that has recently been brought to market and does not feature in the literature reviewed. Although a new unique product in its own right, it has been demonstrated to fit within the common groups of products discussed.

ObjectivesCT of the brain (CTB) for paediatric head injury is used less frequently at tertiary paediatric emergency departments (EDs) in Australia and New Zealand than in North America. In preparation for release of a national head injury guideline and given the high variation in CTB use found in North America, we aimed to assess variation in CTB use for paediatric head injury across hospitals types.MethodsMulticentre retrospective review of presentations to tertiary, urban/suburban and regional/rural EDs in Australia and New Zealand in 2016. Children aged <16 years, with a primary ED diagnosis of head injury were included and data extracted from 100 eligible cases per site. Primary outcome was CTB use adjusted for severity (Glasgow Coma Scale) with 95% CIs; secondary outcomes included hospital length of stay and admission rate.ResultsThere were 3072 head injury presentations at 31 EDs: 9 tertiary (n=900), 11 urban/suburban (n=1072) and 11 regional/rural EDs (n=1100). The proportion of children with Glasgow Coma Score ≤13 was 1.3% in each type of hospital. Among all presentations, CTB was performed for 8.2% (95% CI 6.4 to 10.0) in tertiary hospitals, 6.6% (95% CI 5.1 to 8.1) in urban/suburban hospitals and 6.1% (95% CI 4.7 to 7.5) in regional/rural. Intragroup variation of CTB use ranged from 0% to 14%. The regional/rural hospitals admitted fewer patients (14.6%, 95% CI 12.6% to 16.9%, p<0.001) than tertiary and urban/suburban hospitals (28.1%, 95% CI 25.2% to 31.2%; 27.3%, 95% CI 24.7% to 30.1%).ConclusionsIn Australia and New Zealand, there was no difference in CTB use for paediatric patients with head injuries across tertiary, urban/suburban and regional/rural EDs with similar intragroup variation. This information can inform a binational head injury guideline.

ObjectiveHead injury (HI) is a common presentation to emergency departments (EDs). The risk of clinically important traumatic brain injury (ciTBI) is low. We describe the relationship between Glasgow Coma Scale (GCS) scores at presentation and risk of ciTBI.MethodsPlanned secondary analysis of a prospective observational study of children<18 years who presented with HIs of any severity at 10 Australian/New Zealand centres. We reviewed all cases of ciTBI, with ORs (Odds Ratio) and their 95% CIs (Confidence Interval) calculated for risk of ciTBI based on GCS score. We used receiver operating characteristic (ROC) curves to determine the ability of total GCS score to discriminate ciTBI, mortality and need for neurosurgery.ResultsOf 20 137 evaluable patients with HI, 280 (1.3%) sustained a ciTBI. 82 (29.3%) patients underwent neurosurgery and 13 (4.6%) died. The odds of ciTBI increased steadily with falling GCS. Compared with GCS 15, odds of ciTBI was 17.5 (95% CI 12.4 to 24.6) times higher for GCS 14, and 484.5 (95% CI 289.8 to 809.7) times higher for GCS 3. The area under the ROC curve for the association between GCS and ciTBI was 0.79 (95% CI 0.77 to 0.82), for GCS and mortality 0.91 (95% CI 0.82 to 0.99) and for GCS and neurosurgery 0.88 (95% CI 0.83 to 0.92).ConclusionsOutside clinical decision rules, decreasing levels of GCS are an important indicator for increasing risk of ciTBI, neurosurgery and death. The level of GCS should drive clinician decision-making in terms of urgency of neurosurgical consultation and possible transfer to a higher level of care.

ABSTRACT:Background:The Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND) cohort study of the Canadian Consortium on Neurodegeneration in Aging (CCNA) is a national initiative to catalyze research on dementia, set up to support the research agendas of CCNA teams. This cross-country longitudinal cohort of 2310 deeply phenotyped subjects with various forms of dementia and mild memory loss or concerns, along with cognitively intact elderly subjects, will test hypotheses generated by these teams.Methods:The COMPASS-ND protocol, initial grant proposal for funding, fifth semi-annual CCNA Progress Report submitted to the Canadian Institutes of Health Research December 2017, and other documents supplemented by modifications made and lessons learned after implementation were used by the authors to create the description of the study provided here.Results:The CCNA COMPASS-ND cohort includes participants from across Canada with various cognitive conditions associated with or at risk of neurodegenerative diseases. They will undergo a wide range of experimental, clinical, imaging, and genetic investigation to specifically address the causes, diagnosis, treatment, and prevention of these conditions in the aging population. Data derived from clinical and cognitive assessments, biospecimens, brain imaging, genetics, and brain donations will be used to test hypotheses generated by CCNA research teams and other Canadian researchers. The study is the most comprehensive and ambitious Canadian study of dementia. Initial data posting occurred in 2018, with the full cohort to be accrued by 2020.Conclusion:Availability of data from the COMPASS-ND study will provide a major stimulus for dementia research in Canada in the coming years.

Existing clinical decision rules guide management for head-injured children presenting 24 hours or sooner after injury, even though some may present greater than 24 hours afterward. We seek to determine the prevalence of traumatic brain injuries for patients presenting to emergency departments greater than 24 hours after injury and identify symptoms and signs to guide management.

Phenytoin is the current standard of care for second-line treatment of paediatric convulsive status epilepticus after failure of first-line benzodiazepines, but is only effective in 60% of cases and is associated with considerable adverse effects. A newer anticonvulsant, levetiracetam, can be given more quickly, is potentially more efficacious, and has a more tolerable adverse effect profile. We aimed to determine whether phenytoin or levetiracetam is the superior second-line treatment for paediatric convulsive status epilepticus.

To determine the cost-effectiveness of 3 clinical decision rules in comparison to Australian and New Zealand usual care: the Children's Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE), the Pediatric Emergency Care Applied Research Network (PECARN), and the Canadian Assessment of Tomography for Childhood Head Injury (CATCH).

ObjectiveDespite high-quality paediatric head trauma clinical prediction rules, the management of otherwise asymptomatic young children with scalp haematomas (SH) can be difficult. We determined the risk of intracranial injury when SH is the only predictor variable using definitions from the Pediatric Emergency Care Applied Research Network (PECARN) and Children’s Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE) head trauma rules.DesignPlanned secondary analysis of a multicentre prospective observational study.SettingTen emergency departments in Australia and New Zealand.PatientsChildren <2 years with head trauma (n=5237).InterventionsWe used the PECARN (any non-frontal haematoma) and CHALICE (>5 cm haematoma in any region of the head) rule-based definition of isolated SH in both children <1 year and <2 years.Main outcome measuresClinically important traumatic brain injury (ciTBI; ie, death, neurosurgery, intubation >24 hours or positive CT scan in association with hospitalisation ≥2 nights for traumatic brain injury).ResultsIn children <1 year with isolated SH as per PECARN rule, the risk of ciTBI was 0.0% (0/109; 95% CI 0.0% to 3.3%); in those with isolated SH as defined by the CHALICE, it was 20.0% (7/35; 95% CI 8.4% to 36.9%) with one patient requiring neurosurgery. Results for children <2 years and when using rule specific outcomes were similar.ConclusionsIn young children with SH as an isolated finding after head trauma, use of the definitions of both rules will aid clinicians in determining the level of risk of ciTBI and therefore in deciding whether to do a CT scan.Trial registration numberACTRN12614000463673.

ObjectiveThe National Emergency X-Radiography Utilisation Study II (NEXUS II) clinical decision rule (CDR) can be used to optimise the use of CT in children with head trauma. We set out to externally validate this CDR in a large cohort.MethodsWe performed a prospective observational study of patients aged <18 years presenting with head trauma of any severity to 10 Australian/New Zealand EDs. In a planned secondary analysis, we assessed the accuracy of the NEXUS II CDR (with 95% CI) to detect clinically important intracranial injury (ICI). We also assessed clinician accuracy without the rule.ResultsOf 20 137 total patients, we excluded 28 with suspected penetrating injury. Median age was 4.2 years. CTs were obtained in ED for 1962 (9.8%), of whom 377 (19.2%) had ICI as defined by NEXUS II. 74 (19.6% of ICI) patients underwent neurosurgery.Sensitivity for ICI based on the NEXUS II CDR was 379/383 (99.0 (95% CI 97.3% to 99.7%)) and specificity was 9320/19 726 (47.2% (95% CI 46.5% to 47.9%)) for the total cohort. Sensitivity in the CT-only cohort was similar. Of the 18 022 children without CT in ED, 49.4% had at least one NEXUS II risk criterion. Sensitivity for ICI by the clinicians without the rule was 377/377 (100.0% (95% CI 99.0% to 100.0%)) and specificity was 18 147/19 732 (92.0% (95% CI 91.6% to 92.3%)).ConclusionsNEXUS II had high sensitivity, similar to the derivation study. However, approximately half of unimaged patients were positive for NEXUS II risk criteria; this may result in an increased CT rate in a setting with high clinician accuracy.

Clinical decision rules can help to determine the need for CT imaging in children with head injuries. We aimed to validate three clinical decision rules (PECARN, CATCH, and CHALICE) in a large sample of children.

ObjectiveData on the aetiology of persistent cough at the transitional stage from subacute to chronic cough (>4 weeks duration) are scarce. We aimed to (1) identify the prevalence of chronic cough following acute respiratory illness (ARI) and (2) determine the diagnostic outcomes of children with chronic cough.DesignProspective cohort study.SettingA paediatric emergency department (ED) in Brisbane, Australia.PatientsChildren aged <15 years presenting with an ARI with cough.InterventionsChildren were followed weekly for 28 days;those with a persistent cough at day 28 were reviewed by a paediatric pulmonologist.Main outcome measuresCough persistence at day 28 and pulmonologist diagnosis.Results2586 children were screened and 776 (30%) were ineligible; 839 children (median age=2.3 years, range=0.5 months to 14.7 years, 60% male) were enrolled over 2 years. Most children (n=627, 74.8%) had cough duration of <7 days at enrolment. At day 28, 171/839 (20.4%, 95% CI 17.7 to 23.1) children had persistent cough irrespective of cough duration at enrolment. The cough was wet in 59/171 (34.5%), dry in 45/171 (26.4%) and variable in 28/171 (16.1%). Of these 117 children , 117 (68.4%) were reviewed by a paediatric pulmonologist.
