Early versus late parenteral nutrition in term and late preterm infants: a randomised controlled trial.

BACKGROUND: There is limited evidence regarding the optimal time to commence parenteral nutrition (PN) in term and late preterm infants. DESIGN: Single-centre, non-blinded, exploratory randomised controlled trial. SETTING: A level-3 neonatal unit in a stand-alone paediatric hospital. PATIENTS: Infants born ≥34 weeks of gestation and ≤28 days, who needed PN. Eligible infants were randomised on day 1 or day 2 of admission. INTERVENTIONS: Early (day 1 or day 2 of admission, N=30) or late (day 6 of admission, N=30) PN. MAIN OUTCOME MEASURES: Plasma phenylalanine and F2-isoprostane levels on day 4 and day 8 of admission. Secondary outcomes were amino-acid and fatty-acid profiles on day 4 and day 8, and clinical outcomes. RESULTS: The postnatal age at randomisation was similar between the groups (2.3 (SD 0.8) vs 2.3 (0.7) days, p=0.90). On day 4, phenylalanine levels in early-PN infants were higher than in late-PN (mean (SD) 62.9 (26.7) vs 45.5 (15.3) µmol/L; baseline-adjusted percentage difference 25.8% (95% CI 11.6% to 39.9%), p<0.001). There was no significant difference in phenylalanine levels between the two groups on day 8. There was no significant difference between the groups for F2-isoprostane levels on day 4 (early-PN mean (SD) 389 (176) vs late-PN 419 (291) pg/mL; baseline-adjusted percentage difference: -4.4% (95% CI -21.5% to 12.8%) p=0.62) and day 8 (mean (SD) 305 (125) vs 354 (113) pg/mL; adjusted mean percentage difference -16.1 (95% CI -34.1 to 1.9) p=0.09).Postnatal growth restriction for weight was less severe in the early-PN group (change in weight z-score from baseline to discharge: -0.6 (0.6) vs -1.0 (0.6); p=0.02). The incidence of hyperglycaemia was greater in the early-PN group (20/30 (66.7%) vs 11/30 (36.7%), p=0.02). CONCLUSIONS: The timing of the commencement of PN did not seem to affect the degree of oxidative stress in critically ill term and late preterm infants. The effect of transiently high plasma phenylalanine with early PN on clinical outcomes requires further investigation. TRIAL REGISTRATION NUMBER: ACTRN12620000324910.

Is Social Media Here to Stay?: Survey Results Indicate Increasing Pathologist Interest and Engagement Over Time.

CONTEXT.­: Social media has become widely adopted by pathologists and other physicians for professional purposes. While engagement has likely increased over time, there remain few concrete data regarding attitudes toward its use. OBJECTIVE.­: To assess pathologists' use of and attitudes toward social media over time. DESIGN.­: We created a survey regarding personal and professional use of social media and circulated it via multiple channels in December 2017 and again in February 2022. Results of the 2 surveys were compared for statistically significant differences. RESULTS.­: The 2017 survey was completed by 97 participants, and the 2022 survey by 305 participants. Respondents were predominantly female and academics, included pathologists in all age categories and all time-in-practice length. In both surveys, Twitter (now X) was the most popular platform for professional use and Facebook was the most popular for personal use. Professional barriers to social media use remained consistent between the 2 surveys, including the amount of time required. Education was seen as the main benefit of social media use in both surveys, while other benefits such as networking and increasing professional visibility were endorsed significantly less often in the second survey. While the second survey received more than 3 times as many responses as the first, several aspects of social media use (mainly demographics) remained similar during the timeframe, while other aspects (such as usage and perceived values) decreased. CONCLUSIONS.­: Pathologists continue to find social media valuable. Barriers remain, though overall pathologists of all ages and practice settings appear receptive to using social media to further educational and other opportunities.

Impact of ventilation tube insertion on long-term language outcomes at 6 and 10 years of age: A prospective pregnancy cohort study.

OBJECTIVE: Investigating the impact of early childhood ventilation tube insertion (VTI) on long-term language outcomes. DESIGN: Longitudinal cohort study. SETTING: A total of 2900 pregnant women participated in the Raine Study between 1989 and 1991 in Western Australia, and 2868 children have been followed up. PARTICIPANTS: Based on parental reports, 314 children had a history of recurrent otitis media but did not undergo VTI (rOM group); another 94 received VTI (VTI group); while 1735 had no history of rOM (reference group) in the first 3 years of childhood. Children with data on outcomes and confounders were included in analyses of PPVT-R at ages 6 (n = 1567) and 10 years (n = 1313) and CELF-III at 10 years (n = 1410) (approximately 5% in the VTI group and 15% in the rOM group). MAIN OUTCOME MEASURES: Peabody Picture Vocabulary Test-Revised edition and Clinical Evaluation of Language Fundamentals® Preschool-3. RESULTS: At 6 years, mean PPVT-R scores were significantly lower in the VTI group than the reference group (ß = -3.3; 95% CI [-6.5 to -0.04], p = .047). At 10 years, while the difference between the VTI and reference groups was less pronounced for PPVT-R scores, there was a small but consistent trend of lower measures, on average, across CELF-III scores (expressive: ß = -3.4 [-7.1 to 0.27], p = .069; receptive: ß = -4.1 [-7.9 to -0.34], p = .033; total: ß = -3.9 [-7.5 to -0.21], p = .038). There was no evidence to suggest that language outcomes in the rOM group differed from the reference group. CONCLUSION: Lower scores of language outcomes in school-aged children who received VTI in early childhood may suggest a long-term risk which should be considered alongside the potential benefits of VTI.

The epidemiology of superficial Streptococcal A (impetigo and pharyngitis) infections in Australia: A systematic review.

BACKGROUND: Streptoccocal A (Strep A, GAS) infections in Australia are responsible for significant morbidity and mortality through both invasive (iGAS) and post-streptococcal (postGAS) diseases as well as preceding superficial (sGAS) skin and throat infection. The burden of iGAS and postGAS are addressed in some jurisdictions by mandatory notification systems; in contrast, the burden of preceding sGAS has no reporting structure, and is less well defined. This review provides valuable, contemporaneous evidence on the epidemiology of sGAS presentations in Australia, informing preventative health projects such as a Streptococcal A vaccine and standardisation of primary care notification. METHODS AND FINDINGS: MEDLINE, Scopus, EMBASE, Web of Science, Global Health, Cochrane, CINAHL databases and the grey literature were searched for studies from an Australian setting relating to the epidemiology of sGAS infections between 1970 and 2020 inclusive. Extracted data were pooled for relevant population and subgroup analysis. From 5157 titles in the databases combined with 186 grey literature reports and following removal of duplicates, 4889 articles underwent preliminary title screening. The abstract of 519 articles were reviewed with 162 articles identified for full text review, and 38 articles identified for inclusion. The majority of data was collected for impetigo in Aboriginal and Torres Strait Islander populations, remote communities, and in the Northern Territory, Australia. A paucity of data was noted for Aboriginal and Torres Strait Islander people living in urban centres or with pharyngitis. Prevalence estimates have not significantly changed over time. Community estimates of impetigo point prevalence ranged from 5.5-66.1%, with a pooled prevalence of 27.9% [95% CI: 20.0-36.5%]. All studies excepting one included >80% Aboriginal and Torres Strait Islander people and all excepting two were in remote or very remote settings. Observed prevalence of impetigo as diagnosed in healthcare encounters was lower, with a pooled estimate of 10.6% [95% CI: 3.1-21.8%], and a range of 0.1-50.0%. Community prevalence estimates for pharyngitis ranged from 0.2-39.4%, with a pooled estimate of 12.5% [95% CI: 3.5-25.9%], higher than the prevalence of pharyngitis in healthcare encounters; ranging from 1.0-5.0%, and a pooled estimate of 2.0% [95% CI: 1.3-2.8%]. The review was limited by heterogeneity in study design and lack of comparator studies for some populations. CONCLUSIONS: Superficial Streptococcal A infections contribute to an inequitable burden of disease in Australia and persists despite public health interventions. The burden in community studies is generally higher than in health-services settings, suggesting under-recognition, possible normalisation and missed opportunities for treatment to prevent postGAS. The available, reported epidemiology is heterogeneous. Standardised nation-wide notification for sGAS disease surveillance must be considered in combination with the development of a Communicable Diseases Network of Australia (CDNA) Series of National Guideline (SoNG), to accurately define and address disease burden across populations in Australia. TRIAL REGISTRATION: This review is registered with PROSPERO. Registration number: CRD42019140440.

A Review of Cardiac Surgical Procedures and Their Outcomes for Paediatric Rheumatic Heart Disease in Western Australia.

INTRODUCTION: Surgical intervention is an important treatment modality for advanced rheumatic heart disease (RHD). This study aimed to describe patient characteristics and outcomes from cardiac surgery for RHD in patients referred to the only tertiary paediatric hospital in Western Australia. METHODS: An analysis of patient characteristics and cardiac surgery outcomes in patients with RHD was undertaken, using data from clinical cardiac databases, medical notes, and correspondence from rural outreach clinics. RESULTS: 29 patients (59% female, 97% Aboriginal, Maori or Pacific Islander) underwent 41 valve interventions over 34 cardiac surgeries for RHD between 2000-2018. Median age at first surgery was 12.2 (range 4-16) years. Severe mitral regurgitation (MR) was the most common indication for primary surgery (62%), followed by mixed mitral regurgitation/aortic regurgitation (21%) and severe aortic regurgitation (17%). Mitral valve repair was the most common valve intervention (56%). Two patients had mitral valve replacement (MVR) at first operation, two patients had MVR at second operation and two had MVR at third operation. There was no early mortality. One patient required early (<30 days) reoperation for aortic valve repair failure. Two patients had late reoperations at 3.3 and 6.1 months after the first procedure for MR. Four (14%) patients experienced documented ARF recurrences. Late mortality occurred in 3 (10%) patients, all due to cardiac causes. On last follow-up echocardiogram 5 patients (17%) had moderate MR and none had severe MR. CONCLUSIONS: This is the first study to describe characteristics and outcomes in WA paediatric patients having surgery for RHD. Outcomes are comparable to similar studies, with favourable long-term survival.

Evaluation of the implementation and clinical effects of an intervention to improve medical follow-up and health outcomes for Aboriginal children hospitalised with chest infections.

Background: Aboriginal children hospitalised with acute lower respiratory infections (ALRIs) are at-risk of developing bronchiectasis, which can progress from untreated protracted bacterial bronchitis, often evidenced by a chronic (>4 weeks) wet cough following discharge. We aimed to facilitate follow-up for Aboriginal children hospitalised with ALRIs to provide optimal management and improve their respiratory health outcomes. Methods: We implemented an intervention to facilitate medical follow-up four weeks after hospital discharge from a paediatric hospital in Western Australia. The intervention included six-core components that focused on parents, hospital staff and hospital processes. Both health and implementation outcomes were measured for children grouped by three distinct temporal periods of recruitment: (i) nil-intervention, recruited after hospital admission; (ii) health-information only, received during recruitment at hospital admission, pre-intervention; (iii) post-intervention. The primary outcome was the cough-specific quality-of-life score (PC-QoL) in children with a chronic wet cough following discharge. Findings: Of the 214 patients that were recruited, 181 completed the study. Follow-up rates one-month post-discharge were higher in the post-intervention (50.7%) than the nil-intervention (13.6%) and health-information (17.1%) groups. PC-QoL in children with a chronic wet cough was also improved in the post-intervention group compared the health information and nil-intervention groups (difference in means between nil-intervention and post-intervention groups = 1.83, 95% CI: 0.75, 2.92, p = 0.002), aligning with an increase in the percentage who received evidence-based treatment, namely antibiotics at one-month post-discharge (57.9% versus 13.3%). Interpretation: Implementation of our co-designed intervention to facilitate effective and timely medical follow-up for Aboriginal children hospitalised with ALRIs improved their respiratory health outcomes. Funding: State, national grants and fellowships.

Current parenteral nutrition practice and clinical outcomes of term and late preterm infants: A retrospective study.

BACKGROUND AND AIMS: Limited studies have described parenteral nutrition (PN) practices and clinical outcomes in term and late preterm infants. The aim of this study was to describe the current practice of PN in term and late preterm infants and their short-term clinical outcomes. METHODS: We conducted a retrospective study in a tertiary NICU between October 2018 and September 2019. Infants (gestation ≥34 weeks) admitted on the day of birth or the following day and received PN were included. We collected data on patient characteristics, daily nutrition, clinical and biochemical outcomes until discharge. RESULTS: A total of 124 infants [mean (SD) gestation: 38 (1.92) weeks] were included; 115 (93%) and 77 (77%) commenced on parenteral amino acids and lipids, respectively, by day 2 of admission. The mean parenteral amino acid and lipid intake on day 1 of admission was 1.0 (0.7) g/kg/day and 0.8 (0.6) g/kg/day respectively and increased to 1.5 (1.0) g/kg/day and 2.1 (0.7) g/kg/day by day 5, respectively. Eight (6.5%) infants accounted for 9 episodes of hospital-acquired infections. The mean z-scores for anthropometrics at discharge were significantly lower than at birth (Weight: -0.72 (1.13) vs - 0.04 (1.11); p < 0.001; Head circumference: -0.14 (1.17) vs 0.34 (1.05); p < 0.001; Length: -0.17 (1.69) vs 0.22 (1.34); p < 0.001). A total of 28 (22.6%) and 16 (12.9%) infants had mild and moderate postnatal growth restriction (PNGR), respectively. None had severe PNGR. Thirteen infants (11%) experienced hypoglycaemia, whereas 53 (43%) experienced hyperglycaemia. CONCLUSION: The intakes of parenteral amino acids and lipids in term and late preterm infants were at the lower end of the currently recommended doses, especially in the first five days of admission. One third of the study population had mild to moderate PNGR. Randomised trials investigating the impact of initial PN intakes on clinical, growth and developmental outcomes are recommended.

The association between otitis media in early childhood with later behaviour and attention problems: A longitudinal pregnancy cohort.

OBJECTIVES: The present study aims to investigate the association between an early history of recurrent otitis media (OM) with or without ventilation tube insertion (VTI) and later behavioural problems in childhood and adolescence. METHODS: Parental reports in a longitudinal pregnancy cohort were used to classify children into three groups; recurrent OM without VTI (rOM group; n = 276), recurrent OM with VTI (VTI group; n = 62), and no history of early-life recurrent OM as a reference group (n = 1485). The Child Behaviour Checklist (CBCL) was administered at ages 5, 8, 10, and 13 years and data were analysed for psychological wellbeing. Mixed-effects regression modelling was used to investigate the associations between a history of rOM and CBCL T-scores across all ages for rOM and VTI groups compared to the reference group. All analyses were controlled for a wide range of confounding variables. RESULTS: The analyses revealed a significant association between recurrent OM and behavioural problems. While there was a general decline in scores (i.e. improvement) observed over the duration of the follow-up period, children in the rOM group displayed significantly higher scores for internalising and externalising behaviours at ages five, eight and 10 years. Attention scores were significantly higher across all ages in the rOM group. A transient increase in internalising behaviour was observed in the VTI group at ages eight and 10 years. Logistic regression models showed an increased overall likelihood for the rOM group only to fall within the abnormal clinical range for internalising and externalising behaviours. CONCLUSION: Early-life recurrent OM with and without VTI was associated with increased behavioural and attention problems in early and late childhood. This suggests that recurrent OM can have a significant impact on children's behaviour and attention that can persist into early adolescence.

A Single-Centre Retrospective Review of Modified Blalock-Taussig Shunts: A 22-Year Experience.

INTRODUCTION: This single-centre retrospective study explores demographics and outcomes of patients who underwent a modified Blalock-Taussig shunt (MBTS) over a 22-year period. The predominant surgical approach in this study is a lateral thoracotomy, in contrast to a midline sternotomy. Risks and outcomes of this approach are compared with national and international literature. MATERIALS AND METHODS: Demographic, anatomical, clinical, surgical and outcome data of all patients who underwent a MBTS between 2000 and 2022 were collected and analysed, excluding Norwood procedures, which are not performed at this institution. Short- and long-term morbidity and mortality is described. RESULTS: Over the 22-year study period, 185 MBTS were performed in 162 patients, at a median age of 16 days (interquartile range [IQR] 5-59 days) and weight of 3.47 kg (IQR 3-4.25 kg, minimum weight 2 kg). Of these, 79% of patients had a biventricular circulation. Cardiac diagnoses included both univentricular and biventricular anatomy; tetralogy of Fallot (TOF) (36%), transposition of the great arteries/ventricular septal defect/pulmonary stenosis (TGA/VSD/PS) (11%), pulmonary atresia with intact ventricular septum (PA/IVS) (23%), pulmonary atresia with ventricular septal defect (PA/VSD) (14%), other (16%). The most common size of MBTS was 4 mm (71%); 93% were performed via a lateral thoracotomy. There were 47 cases of major operative morbidity, which did not differ significantly with cardiac diagnosis. Overall all-cause mortality was 13.5%. Early operative mortality was 4.3%. Mortality varied with cardiac diagnosis, 6% with TOF and 19% with PA/IVS. There was no era effect on mortality rates, however a lower frequency of major morbidity (23% vs 7%, p=0.03) was observed in the most recent third of the study period. Risk factors for shunt reintervention or mortality included weight <2.5 kg (HR=2.79 [1.37, 5.65], p=0.005), and pre- (HR=3.31 [1.86, 5.9], p<0.001) or postoperative lactic acidosis (HR=1.37 [1.25,1.5], p<0.001). These rates are comparable to those in the literature, with the predominant approach a midline sternotomy. CONCLUSION: Mortality rates and risk factors for adverse outcomes are comparable to those previously reported for both univentricular and biventricular groups. These results highlight that outcomes of MBTS performed via lateral thoracotomy are comparable to those by midline sternotomy as reported in the literature. Operating via the lateral approach may be advantageous as it avoids the complications of a midline sternotomy.

Prevalence of chronic respiratory diseases in Aboriginal children: A whole population study.

BACKGROUND: The burden of bronchiectasis is disproportionately high in Aboriginal adults, with early mortality. Bronchiectasis precursors, that is, protracted bacterial bronchitis (PBB) and chronic suppurative lung disease (CSLD), often commence in early childhood. We previously reported a 10% prevalence of PBB in Aboriginal children aged 0 to 7 years, however there are no data on prevalence of chronic lung diseases in older children. Our study aimed to determine the prevalence of PBB, CSLD, bronchiectasis, and asthma in Aboriginal children living in four communities. METHODS: A whole-population cross-sectional community co-designed study of Aboriginal children aged <18-years in four remote communities in Western Australia across two-time points, a month apart. Children were assessed by pediatric respiratory clinicians with spirometry undertaken (when possible) between March-September 2021. Children with respiratory symptoms were followed up via medical record audit from either the local medical clinic or via a respiratory specialist clinic through to March 2022 to establish a final diagnosis. FINDINGS: We recruited 392 (91.6%) of those in the selected communities; median age = 8.4 years (interquartile range [IQR] 5.1-11.5). Seventy children (17.9%) had a chronic respiratory pathology or abnormal spirometry results. PBB was confirmed in 30 (7.7%), CSLD = 13 (3.3%), bronchiectasis = 5 (1.3%) and asthma = 17 (4.3%). The prevalence of chronic wet cough significantly increased with increasing age. INTERPRETATION: The prevalence of PBB, CSLD and bronchiectasis is high in Aboriginal children and chronic wet cough increases with age. This study highlights the high disease burden in Aboriginal children and the urgent need for strategies to address these conditions.

Early versus late parenteral nutrition in term and late preterm infants: study protocol for a randomised controlled trial.

BACKGROUND: Despite the wide use of parenteral nutrition (PN) in neonatal intensive care units (NICU), there is limited evidence regarding the optimal time to commence PN in term and late preterm infants. The recommendations from the recently published ESPGHAN/ESPEN/ESPR/CPEN and NICE guidelines are substantially different in this area, and surveys have reported variations in clinical practice. The aim of this randomised controlled trial (RCT) is to evaluate the benefits and risks of early versus late PN in term and late preterm infants. METHODS/DESIGN: This study is a single-centre, non-blinded RCT in the NICU of Perth Children's Hospital, Western Australia.A total of 60 infants born ≥34 weeks of gestation who have a high likelihood of intolerance to enteral nutrition (EN) for at least 3-5 days will be randomised to early (day 1 or day 2 of admission) or late commencement (day 6 of admission) of PN after informed parental consent. In both groups, EN will be commenced as early as clinically feasible. Primary outcomes are plasma phenylalanine and plasma F2-isoprostane levels on Day 4 and Day 8 of admission. Secondary outcomes are total and individual plasma amino acid profiles, plasma and red blood cell fatty acid profiles, in-hospital all-cause mortality, hospital-acquired infections, length of hospital/NICU stay, z scores and changes in z scores at discharge for weight, height and head circumference, time to full EN, duration of respiratory (mechanical, non-invasive) support, duration of inotropic support, the incidence of hyper and hypoglycaemia, incidence of metabolic acidosis, liver function, blood urea nitrogen, and C-reactive protein (CRP). DISCUSSION: This RCT will examine the effects of early versus late PN in term and late preterm infants by comparing key biochemical and clinical outcomes and has the potential to identify underlying pathways for beneficial or harmful effects related to the timing of commencement of PN in such infants. TRIAL REGISTRATION: ANZCTR; ACTRN12620000324910 (3rd March 2020).

Childhood Systemic Lupus Erythematosus: Presentation, management and long-term outcomes in an Australian cohort.

OBJECTIVES: Systemic Lupus Erythematosus (SLE) is a serious autoimmune disease often resulting in major end-organ damage and increased mortality. Currently, no data exists focussing on the presentation, long-term management and progression of SLE in the Australian paediatric population. We conducted the first Australian longitudinal review of childhood SLE, focussing on response to treatment and outcomes. METHODS: Detailed clinical and laboratory data of 42 children diagnosed with SLE before 16 years from 1998 to 2018 resident in Western Australia was collected. Data was collected at diagnosis and key clinical review time points and compared using the Systemic Lupus Collaborating Clinics (SLICC) and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) criteria. End organ damage was assessed against Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). Incidence rates of disease complications and end organ damage were determined. RESULTS: Of the 42 children, 88% were female with average age at diagnosis of 12.5 years. Indigenous Australians were over represented with an incidence rate 18-fold higher than non-Indigenous, although most children were Caucasian, reflecting the demographics of the Australian population. Median duration of follow-up was 4.25 years. On final review, 28.6% had developed cumulative organ damage as described by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (incidence rate: 0.08/PY (95% CI 0.04-0.14)), and one child died. Twenty-nine children had renal involvement (incidence rate: 0.38/PY (95% CI 0.26-0.56)). Of the 27 patients with biopsy proven lupus nephritis, 70% had Class III or IV disease. Average length of prednisolone use from diagnosis was 32.5 months. Hydroxychloroquine (n = 36) and mycophenolate mofetil (n =21) were the most widely used steroid sparing agents. 61.9% received rituximab and/or cyclophosphamide. CONCLUSION: This is the first longitudinal retrospective review of Australian children with SLE, with a markedly higher incidence in Indigenous children. Although improving, rates of end organ complications remain high, similar to international cohort outcomes. Longitudinal multi-centre research is crucial to elucidate risk factors for poor outcomes, and identifying those warranting early more aggressive therapy.

Looking beyond: complex holistic care needs of Syrian and Iraqi refugee children and adolescents.

OBJECTIVE: Protracted international conflict has seen escalating numbers of displaced and resettled Syrian and Iraqi refugees, raising concerns for their health and well-being. This paper describes the demographic and clinical profiles of recently resettled Syrian and Iraqi refugee children and adolescents across physical, psychosocial, developmental and educational domains using standardised multidisciplinary assessments. DESIGN: A cross-sectional observational study was undertaken of initial specialist paediatric multidisciplinary Refugee Health Service assessments completed at the tertiary paediatric hospital (Western Australia) between June 2015 and September 2019. RESULTS: Three hundred and twenty-seven children and adolescents (264 Syrian, 63 Iraqi) were assessed following resettlement. Witnessed trauma (86%) and disclosed adversity (median Refugee Adverse Childhood Experiences score 3, range 1-14) were universally high. Almost all patients had health issues identified across physical (99%), psychosocial (76%) and developmental/educational (75%) domains. Interrupted education (65%) and death of a family member (16%) were significantly associated with psychological morbidities. Common comorbidities included dental caries (78%), non-infectious disease (76%), vitamin D deficiency (72%), malnutrition (46%; overweight/obesity 23%), and psychological (32%; post-traumatic stress disorder 4.3%) and developmental (9.5%) concerns. Emerging and alarming child protection concerns were prevalent (17%), with females demonstrating especially high risks. CONCLUSION: This is the largest comprehensive study demonstrating the complex and cross-dimensional health needs and specific vulnerabilities of resettled Syrian and Iraqi refugee children and adolescents. Early comprehensive standardised multidisciplinary paediatric assessments, and culturally safe, trauma-informed interventions and follow-up are required to optimise resettlement outcomes and promote well-being.

Communicating Certainty in Pathology Reports.

CONTEXT.­: Pathology reports are the main modality in which results are communicated to other physicians. For various reasons, the diagnosis may be qualified on a spectrum of uncertainty. OBJECTIVE.­: To examine how communication of uncertainty is an unexamined source of possible medical error. No study to our knowledge has examined pathology reports across multiple institutions. This study seeks to identify commonly used phrases of diagnostic uncertainty and their interpreted meanings by surgical pathologists and clinicians. DESIGN.­: Anonymous surveys were completed at 3 major US academic institutions by 18 practicing staff pathologists, 12 pathology residents, 53 staff clinicians, and 50 resident/allied health professional clinicians at 5 standard tumor boards. All participants rated percentage certainty associated with 7 diagnostic terms. Pathologists answered 2 questions related to the ability to clarify a diagnosis using a comment and comfort wording pathology reports. Clinicians answered questions on how often they read a pathology report comment, if they found the comment helpful, and how comfortable they were in reading pathology reports. RESULTS.­: A wide range in percentage certainty was found for each of the 7 diagnostic phrases. Both staff and resident clinicians and residents showed wide variability in interpreting the phrases. Twenty-five of 50 staff clinicians (52%) were very comfortable reading a pathology report, whereas only 4 of 53 resident clinicians (8%) were very comfortable reading a pathology report. Twenty-four of 53 staff clinicians (63%) reported always reading the comment, yet only 20 of 53 (27%) always found the comment helpful. The phrases "diagnostic of" and "consistent with" had the strongest agreement in meaning. The weakest agreement was between "suspicious for" and "compatible with." CONCLUSIONS.­: Efforts to standardize diagnostic terms may improve communication.

Evaluation of an Australian neurological nurse-led model of postdischarge care.

Neurological disorders are a leading cause of disease burden worldwide, placing a heavy demand on health systems. This study evaluated the impacts and cost savings of a community-based nursing service providing supported discharge for neurological patients deemed high-risk for unplanned emergency department presentations and/or hospital readmissions. It focused on adult patients with stroke, epilepsy, migraine/headache or functional neurological disorders discharged from a Western Australian tertiary hospital. An observational design was used comprising prospective enrolment of patients receiving nurse-led supported discharge and follow-up (Neurocare), 21 August 2018 to 6 December 2019 (N = 81), and hospital administrative data, 1 February 2016 to 31 January 2018, for patients in previous care model (N = 740). Healthcare utilisation and annualised cost savings from reduced rehospitalisation and/or emergency department presentations within 28 days post discharge were compared. Neurocare patients' postdischarge functional and health-related quality of life outcomes, and perceived involvement in self-management and integrated care were surveyed. The hospital's total cost savings are A$101,639 per annum and A$275/patient/year with a return on investment of 2.01. There was no significant difference in hospital length of stay (LOS) between models, but older age was associated with longer length of hospital stay and a predictor for non-neurological readmissions. Neurocare patients showed improved functional status, less equipment and/or service needs, improved health-related quality of life. They felt involved in self-managing their condition with well-integrated postdischarge care. This nurse-led model of transitional care for neurology patients discharged from hospital produced cost savings and a positive return on investment compared with usual care. With service maturity, earlier supported hospital discharge and reduced LOS may follow. Patients' reduced service needs and improved functional status and health-related quality of life may positively impact healthcare utilisation. Future research should include larger patient samples and multiple sites.

Protocol for the systematic review of the epidemiology of superficial Streptococcal A infections (skin and throat) in Australia.

OBJECTIVE: We have produced a protocol for the comprehensive systematic review of the current literature around superficial group A Streptococcal infections in Australia. METHODS: MEDLINE, Scopus, EMBASE, Web of Science, Global Health, Cochrane, CINAHL databases and the gray literature will be methodically and thoroughly searched for studies relating to the epidemiology of superficial group A Streptococcal infections between the years 1970 and 2019. Data will be extracted to present in the follow up systematic review. CONCLUSION: A rigorous and well-organised search of the current literature will be performed to determine the current and evolving epidemiology of superficial group A Streptococcal infections in Australia.

Supporting Patient-Clinician Interaction in Chronic HIV Care: Design and Development of a Patient-Reported Outcomes Software Application.

BACKGROUND: The consideration of health-related quality of life (HRQL) is a hallmark of best practice in HIV care. Information technology offers an opportunity to more closely engage patients with chronic HIV infection in their long-term management and support a focus on HRQL. However, the implementation of patient-reported outcome (PRO) measures, such as HRQL in routine care, is challenged by the need to synthesize data generated by questionnaires, the complexity of collecting data between patient visits, and the integration of results into clinical decision-making processes. OBJECTIVE: Our aim is to design and pilot-test a multimedia software platform to overcome these challenges and provide a vehicle to increase focus on HRQL issues in HIV management. METHODS: A multidisciplinary team in France and Australia conducted the study with 120 patients and 16 doctors contributing to the design and development of the software. We used agile development principles, user-centered design, and qualitative research methods to develop and pilot the software platform. We developed a prototype application to determine the acceptability of the software and piloted the final version with 41 Australian and 19 French residents using 2 validated electronic questionnaires, the Depression, Anxiety and Stress Scale-21 Items, and the Patient Reported Outcomes Quality of Life-HIV. RESULTS: Testing of the prototype demonstrated that patients wanted an application that was intuitive and without excessive instruction, so it felt effortless to use, as well as secure and discreet. Clinicians wanted the PRO data synthesized, presented clearly and succinctly, and clinically actionable. Safety concerns for patients and clinicians included confidentiality, and the potential for breakdown in communication if insufficient user training was not provided. The final product, piloted with patients from both countries, showed that most respondents found the application easy to use and comprehend. The usability testing survey administered found that older Australians had reduced scores for understanding the visual interface (P=.004) and finding the buttons organized (P=.02). Three-fourths of the respondents were concerned with confidentiality (P=.007), and this result was more prevalent in participants with higher anxiety and stress scores (P=.01), as measured by the Depression, Anxiety and Stress Scale-21 Items. These statistical associations were not observed in 15 French patients who completed the same questionnaire. CONCLUSIONS: Digital applications in health care should be safe and fit for purpose. Our software was acceptable to patients and shows potential to overcome some barriers to the implementation of PROs in routine care. The design of the clinicians' interface presents a solution to the problem of voluminous data, both synthesizing and providing a snapshot of longitudinal data. The next stage is to conduct a randomized controlled trial to determine whether patients experience increased satisfaction with care and whether doctors perceive that they deliver better clinical care without compromising efficiency.

Maternal diet, depression and antidepressant treatment in pregnancy and across the first 12 months postpartum in the MPEWS pregnancy cohort study: Perinatal diet, depression and antidepressant use.

BACKGROUND: There is increasing interest in the association between perinatal depression and diet including whether diet may have an impact on depressive symptoms and equally whether depression influences diet. Furthermore, whether pharmacological treatment of depression with antidepressant medication also may influence diet. METHODS: We examine diet, perinatal depression, and antidepressant use in 442 women recruited in early pregnancy and followed until 12 months postpartum as part of the Mercy Pregnancy Emotional Wellbeing Study. Measures included Structured Clinical Interview for the DSM at recruitment in early pregnancy and comprehensive dietary intake questions, Edinburgh Postnatal Depression Scale, and self-report and recorded antidepressant use at third trimester and 6 and 12 months postpartum. RESULTS: This study found that those women with untreated, current depression in pregnancy had higher unhealthy takeaway food intake across the perinatal period compared to those taking antidepressant medication or healthy control women, albeit the overall effects were small and the clinical significance unknown. Higher depressive symptoms in the postpartum were also associated with higher takeaway intake. There was no difference in fruit and vegetable intake between the three groups and intake was highest for all women late in pregnancy and declined in the postpartum period. In all, women's takeaway food intake increased from pregnancy across the postpartum. LIMITATIONS: Lack of information on pre-pregnancy diet. CONCLUSIONS: Unhealthy takeaway intake was found to be associated with depression; however, for those women who took antidepressant treatment, their diet patterns were similar to healthy controls. Future research should examine the relationship of treatments for depression in addition to depression and associated dietary behaviours.

Frequent occurrence of low-level positive autoantibodies in chronic hepatitis C.

Evidence of autoimmune disease associated with hepatitis C virus (HCV)-infection has important clinical implications. A systematic profile of these autoantibodies in relevant clinical cohorts relative to healthy controls is needed to better inform current standard of care for chronic hepatitis C. Samples from an Australian cohort of chronic HCV-infected subjects (n=127) were tested for the presence of 19 diagnostic autoantibodies and compared with data available from a control cohort representing a general Caucasian population (n=198). Chronic HCV-infected individuals had a greater number of autoantibodies than controls (p<0.0001). Anti-nuclear antibodies (ANA) followed by anti-smooth muscle antibodies (SMA) were the most frequently detected autoantibodies within the HCV cohort and significantly more than in the control cohort (p<0.0001 and p=0.006, respectively). However, for most autoantibody assays the 95th percentile approximated the reference value for positivity. None of the autoantibodies were significantly associated with age or sex for the HCV cohort, except SMA positivity that was significantly higher in chronic HCV-infected male subjects (p<0.0001). Autoantibodies found in chronic HCV-infected subjects were commonly low positive and not disease-specific. Accordingly, general screening for autoimmunity in HCV-infected subjects should not be performed unless there is high clinical suspicion of an underlying autoimmune disease.
