BACKGROUND: The undersupply of health professionals in rural areas impacts healthcare access for those living in rural Australia. A strategy to increase the rural health workforce is to recruit and educate rural people. However, long-standing inequities for rural Australians in accessing tertiary education persist. The aim of this study was to audit the 2023 offerings of Australian allied health, nursing, dental and medical university courses to identify geographical availability and those delivered online. METHODS: A desktop audit of Australian allied health, nursing, dental and medical courses offered in 2023 was undertaken to identify the courses and delivery modes of those courses offered in regional, rural and remote locations. The audit involved searching lists of professionally accredited courses and university websites, which is publicly available information about health courses. Data were tabulated and descriptive statistics used for data analysis. RESULTS: There were marked differences in online and rural course offerings across health professions in Modified Monash (MM) Model category 2-7 locations. Nursing/midwifery had the most courses while pharmacy, podiatry, dental and medicine had few offerings and optometry had none. Social work, nursing/midwifery and psychology also had the most online course offerings. Most courses were offered in MM2 and MM3 locations with few offerings in rural or remote areas. The availability of studying part-time was very limited and often this was only for the early years of the course. Inconsistencies relating to the course information on university websites existed relating to course delivery mode descriptions. CONCLUSIONS: There is a lack of rural on-campus or online course offerings for some allied health disciplines, dentistry and medicine. Provision of end-to-end, flexible courses in rural areas or online is needed to reduce access barriers for rural students and to enable sustainable rural health workforce developme

IMPORTANCE: Multiple SARS-CoV-2 variants have emerged over the COVID-19 pandemic. The implications for COVID-19 severity in children worldwide are unclear. OBJECTIVE: To determine whether the dominant circulating SARS-CoV-2 variants of concern (VOCs) were associated with differences in COVID-19 severity among hospitalized children. DESIGN, SETTING, AND PARTICIPANTS: Clinical data from hospitalized children and adolescents (younger than 18 years) who were SARS-CoV-2 positive were obtained from 9 countries (Australia, Brazil, Italy, Portugal, South Africa, Switzerland, Thailand, UK, and the US) during 3 different time frames. Time frames 1 (T1), 2 (T2), and 3 (T3) were defined to represent periods of dominance by the ancestral virus, pre-Omicron VOCs, and Omicron, respectively. Age groups for analysis were younger than 6 months, 6 months to younger than 5 years, and 5 to younger than 18 years. Children with an incidental positive test result for SARS-CoV-2 were excluded. EXPOSURES: SARS-CoV-2 hospitalization during the stipulated time frame. MAIN OUTCOMES AND MEASURES: The severity of disease was assessed by admission to intensive care unit (ICU), the need for ventilatory support, or oxygen therapy. RESULTS: Among 31 785 hospitalized children and adolescents, the median age was 4 (IQR 1-12) years and 16 639 were male (52.3%). In children younger than 5 years, across successive SARS-CoV-2 waves, there was a reduction in ICU admission (T3 vs T1: risk ratio [RR], 0.56; 95% CI, 0.42-0.75 [younger than 6 months]; RR, 0.61, 95% CI; 0.47-0.79 [6 months to younger than 5 years]), but not ventilatory support or oxygen therapy. In contrast, ICU admission (T3 vs T1: RR, 0.39, 95% CI, 0.32-0.48), ventilatory support (T3 vs T1: RR, 0.37; 95% CI, 0.27-0.51), and oxygen therapy (T3 vs T1: RR, 0.47; 95% CI, 0.32-0.70) decreased across SARS-CoV-2 waves in children 5 years to younger than 18 years old. The results were consistent when data were restricted to unvaccinated children. CONC

Influenza is a common cause of acute respiratory infection, and is a major cause of morbidity and mortality. This report summarises the epidemiology of hospitalisations with laboratory-confirmed influenza during the 2019 influenza season. The Influenza Complications Alert Network (FluCAN) is a sentinel hospital-based surveillance program that operates at sites in all jurisdictions in Australia. Cases were defined as patients hospitalised at any of the 17 sentinel hospitals with influenza confirmed by nucleic acid detection. Data were also collected on a frequency matched control group of influenza-negative patients admitted with acute respiratory infection. During the period 1 April to 31 October 2019 (the 2019 influenza season), there were 4,154 patients admitted with confirmed influenza to one of 17 FluCAN sentinel hospitals. Of these, 44% were elderly (>= 65 years), 21% were children (< 16 years), 7.7% were Aboriginal and Torres Strait Islander peoples, 1.7% were pregnant and 73% had chronic comorbidities. Most admissions were due to influenza A infection (85%). Estimated vaccine coverage was 75% in the elderly, 49% in non-elderly adults with medical comorbidities, and 27% in young children (< 5 years). The estimated vaccine effectiveness in the target adult population was 42% (95% confidence interval [95% CI]: 36%, 49%). There were a larger number of hospital admissions detected with confirmed influenza in this national observational surveillance system in 2019 than in 2018.Copyright © Commonwealth of Australia CC BY-NC-ND.

Introduction: Influenza is a common cause of acute respiratory infection, and is a major cause of morbidity and mortality. Coronavirus disease 2019 (COVID-19) is an acute respiratory infection that emerged as a pandemic worldwide before the start of the 2020 Australian influenza season. This report summarises the epidemiology of hospitalisations with laboratory-confirmed influenza and COVID-19 during the 2020 influenza season in a sentinel surveillance system. Method(s): The Influenza Complications Alert Network (FluCAN) is a sentinel hospital-based surveillance program that operates at sites in all jurisdictions in Australia. Influenza and COVID-19 cases were defined as patients hospitalised at sentinel hospitals and confirmed by nucleic acid detection. Result(s): There were 448 patients with COVID-19 admitted between 16 March and 31 December 2020, and only 20 patients with influenza admitted between 1 April and 30 November 2020, to one of 22 FluCAN hospitals. Of the COVID-19 cases, 173 (39%) were > 65 years of age, 36 (8%) were children (< 16 years), 6 (1%) were Aboriginal and Torres Strait Islander peoples, 4 (1%) were pregnant and 289 (65%) had chronic comorbidities. COVID-19 hospital admissions peaked between weeks 13 and 15 (first wave) nationally, and again between weeks 31 and 35 (Victoria), with most admissions represented by those above 40 years of age. Discussion(s): There was an unusually low number of hospital admissions with laboratory-confirmed influenza in this season, compared to recent seasons. This is likely to be due to effective public health interventions and international border closures as a result of a rise in COVID-19 respiratory infections and associated hospitalisations.Copyright © Commonwealth of Australia CC BY-NC-ND.

Human respiratory syncytial virus (RSV) is an important cause of acute respiratory infection with the most severe disease in the young and elderly. Non-pharmaceutical interventions and travel restrictions for controlling COVID-19 have impacted the circulation of most respiratory viruses including RSV globally, particularly in Australia, where during 2020 the normal winter epidemics were notably absent. However, in late 2020, unprecedented widespread RSV outbreaks occurred, beginning in spring, and extending into summer across two widely separated regions of the Australian continent, New South Wales (NSW) and Australian Capital Territory (ACT) in the east, and Western Australia. Through genomic sequencing we reveal a major reduction in RSV genetic diversity following COVID-19 emergence with two genetically distinct RSV-A clades circulating cryptically, likely localised for several months prior to an epidemic surge in cases upon relaxation of COVID-19 control measures. The NSW/ACT clade subsequently spread to the neighbouring state of Victoria and to cause extensive outbreaks and hospitalisations in early 2021. These findings highlight the need for continued surveillance and sequencing of RSV and other respiratory viruses during and after the COVID-19 pandemic, as mitigation measures may disrupt seasonal patterns, causing larger or more severe outbreaks.

This is likely to be due to effective public health interventions and international border closures as a result of a rise in COVID-19 respiratory infections and associated hospitalisations.

The reported frequency and types of adverse events following initial vaccination and revaccination with Bacille Calmette-Guérin (BCG) varies worldwide. Using active surveillance in a randomised controlled trial of BCG vaccination (the BRACE trial), we determined the incidence and risk factors for the development of BCG injection site abscess and regional lymphadenopathy. Injection site abscess occurred in 3% of 1387 BCG-vaccinated participants; the majority (34/41, 83%) resolved without treatment. The rate was higher in BCG-revaccinated participants (OR 3.6, 95% CI 1.7-7.5), in whom abscess onset was also earlier (median 16 vs. 27 days, p = 0.008). No participant with an abscess had a positive interferon-gamma release assay. Regional lymphadenopathy occurred in 48/1387 (3%) of BCG-vaccinated participants, with a higher rate in revaccinated participants (OR 2.1, 95% CI 1.1-3.9). BCG-associated lymphadenopathy, but not injection site abscess, was influenced by age and sex. A previous positive tuberculin skin test was not associated with local reactions. The increased risk of injection site abscess or lymphadenopathy following BCG revaccination is relevant to BCG vaccination policy in an era when BCG is increasingly being considered for novel applications.

AIM: Victoria experienced two 'waves' of COVID-19 between March and September 2020 and more cases than any other jurisdiction in Australia. Although world-wide reports of COVID-19 reflect that children are less likely to experience severe disease compared with adults, hospitalisations and deaths have been reported. We report testing and outcomes of children with SARS-CoV-2 infection presenting to a tertiary paediatric hospital in Melbourne. METHODS: We conducted a prospective cohort study at The Royal Children's Hospital (RCH), including all children and adolescents (aged 0-18 years) who presented and were tested for SARS-CoV-2 over a 6-month period, between 21 March 2020, up to the 21 September 2020. Detailed epidemiological and clinical data were recorded. RESULTS: A total of 19 708 tests for SARS-CoV-2 were performed in 14 419 patients. One hundred and eighty patients tested positive for SARS-CoV-2 (1.2%). 110 (61%) were symptomatic, 60 (33%) were asymptomatic and 10 (6%) were pre-symptomatic. Close contacts of a positive case were associated with a higher risk of a testing positive for SARS-CoV-2 (120/2027 (6%) vs. 60/14589 (0.4%), RD 5.5 (95% CI 4.5 to 6.5), P < 0.001). Eighteen (10%) SARS-CoV-2-positive patients were admitted to hospital with one patient requiring intensive care. All patients recovered fully with no deaths. CONCLUSION: In Victorian children presenting to a tertiary hospital, SARS-CoV-2 infection caused predominantly mild or asymptomatic infection, with most children not requiring hospitalisation.

BACKGROUND: Respiratory syncytial virus (RSV) is the most common cause of acute lower respiratory infection in young children. We previously estimated that in 2015, 33·1 million episodes of RSV-associated acute lower respiratory infection occurred in children aged 0-60 months, resulting in a total of 118 200 deaths worldwide. Since then, several community surveillance studies have been done to obtain a more precise estimation of RSV associated community deaths. We aimed to update RSV-associated acute lower respiratory infection morbidity and mortality at global, regional, and national levels in children aged 0-60 months for 2019, with focus on overall mortality and narrower infant age groups that are targeted by RSV prophylactics in development. METHODS: In this systematic analysis, we expanded our global RSV disease burden dataset by obtaining new data from an updated search for papers published between Jan 1, 2017, and Dec 31, 2020, from MEDLINE, Embase, Global Health, CINAHL, Web of Science, LILACS, OpenGrey, CNKI, Wanfang, and ChongqingVIP. We also included unpublished data from RSV GEN collaborators. Eligible studies reported data for children aged 0-60 months with RSV as primary infection with acute lower respiratory infection in community settings, or acute lower respiratory infection necessitating hospital admission; reported data for at least 12 consecutive months, except for in-hospital case fatality ratio (CFR) or for where RSV seasonality is well-defined; and reported incidence rate, hospital admission rate, RSV positive proportion in acute lower respiratory infection hospital admission, or in-hospital CFR. Studies were excluded if case definition was not clearly defined or not consistently applied, RSV infection was not laboratory confirmed or based on serology alone, or if the report included fewer than 50 cases of acute lower respiratory infection. We applied a generalised linear mixed-effects model (GLMM) to estimate RSV-associated acute lower respir

Safety and efficacy of vaccines against the SARS-CoV-2 coronavirus has been demonstrated in clinical trials and next by their real world use through the course of the ongoing COVID-19 pandemic. However, very rare adverse events have been detected post-authorization in certain parts of the world. This meeting report summarizes an EMA workshop’s discussion on the epidemiology, clinical presentation and biology of thrombosis with thrombocytopenia syndrome after adenovirus vector COVID-19 vaccination. General agreement was reached by international regulators, scientists and developers on the steps needed to fill the gaps in the characterization of this new syndrome. In particular, actions should be taken to improve the post-vaccination surveillance activities in low and middle income countries and investigate potential genetic predisposition factors.

Alpha2 receptor agonists (alpha2-agonists) are useful sedative and analgesic agents in sheep, but have adverse pulmonary effects, which are reportedly similar between different alpha2-agonists. This randomized crossover study compared pulmonary function after intravenous administration of an alpha2-agonist, either xylazine or an equipotent dose of medetomidine in 34 female sheep anaesthetized twice. Pulmonary function was assessed using spirometry, volumetric capnography, arterial blood gas analysis 1 min prior to, and 5 and 10 min after administration of the allocated alpha 2 agonist drug. Pulmonary structural changes were subsequently assessed using computed tomography (CT). Tachypnoea or hypoxaemia prompted reversal with atipamezole and exclusion of data. Data were analysed for a fixed effect of drug using a mixed effect linear model with significance set at p < 0.05. Ten sheep administered xylazine required atipamezole while none of sheep receiving medetomidine did. Xylazine produced significantly higher respiratory frequency, airway pressures, airway resistance and arterial carbon dioxide (CO2), and lower dynamic compliance, tidal volume, CO2 elimination and end tidal CO2 tension and arterial oxygen tension than medetomidine. This was associated with a significantly lower % of aerated tissue and higher % poorly and non-aerated tissue in CT images of sheep receiving xylazine versus medetomidine. In conclusion, xylazine administration produced marked decreases in pulmonary function, in ventilated isoflurane anaesthetized sheep, when compared to an equipotent dose of medetomidine when administered as an intravenous bolus supporting the use of medetomidine when alpha2-agonists are required.

INTRODUCTION: The Paediatric Active Enhanced Disease Surveillance (PAEDS) network is an Australian hospital-based active surveillance system employing prospective case ascertainment for selected serious childhood conditions, particularly vaccine preventable diseases and potential adverse events following immunisation (AEFI). This report presents surveillance data for 2019. METHODS: Specialist nurses screened hospital admissions, emergency department records, laboratory and other data on a daily basis in seven paediatric tertiary referral hospitals across Australia, to identify children with the conditions under surveillance. Standardised protocols and case definitions were used across all sites. In 2019, the conditions under surveillance comprised: acute flaccid paralysis (AFP; a syndrome associated with poliovirus infection), acute childhood encephalitis (ACE), influenza, intussusception (IS; a potential AEFI with rotavirus vaccines), pertussis, varicella-zoster virus infection (varicella and herpes zoster), invasive meningococcal and invasive Group A streptococcus diseases and two new conditions, Kawasaki disease and gram-negative bloodstream infections. An additional social research component continued to evaluate parental attitudes to influenza vaccination. RESULTS: PAEDS captured 2,701 cases for 2019 across all conditions under surveillance. Key outcomes of PAEDS included: contribution to national AFP surveillance to reach the World Health Organization reporting targets for detection of poliomyelitis cases; demonstration of high influenza activity in 2019 and influenza-associated deaths in ACE cases; identification of key barriers to influenza vaccination of children hospitalised for acute respiratory illness; reporting of all IS cases associated with vaccine receipt to relevant state health department; and showing a further reduction nationally in varicella cases. Enhanced pertussis surveillance continued to capture controls to support vaccine efficacy estimat

OBJECTIVES: To assess the safety of live attenuated herpes zoster vaccine live (ZVL) through cumulative analysis of near real-time, participant-based active surveillance from Australia's AusVaxSafety system. DESIGN AND SETTING: ZVL was funded in Australia for adults aged 70 years from November 2016, with a time-limited catch up programme for those up to 79 years. This cohort study monitored safety in the first two programme years through active surveillance at 246 sentinel surveillance immunisation sites. PARTICIPANTS: Adults aged 70-79 years vaccinated with ZVL who responded to an opt-out survey sent via automated short message service (SMS) 3 days following vaccination (n=17 458) or contributed supplementary data through a separate, opt-in online survey at 16 and 24 days following vaccination (n=346). PRIMARY AND SECONDARY OUTCOME MEASURES: Rates of overall and prespecified adverse events following immunisation (AEFI) by sex, concomitant vaccination and underlying medical condition. Signal detection methods (fast initial response cumulative summation and Bayesian updating analyses) were applied to reports of medical attendance. RESULTS: The median age of participants was 72 years; 53% were female. The response rate following automated SMS was high (73% within 7 days of vaccination). Females were more likely than males to report any adverse event within 7 days of vaccination (RR 2.07, 95% CI 1.86 to 2.31); injection site reaction was the most commonly reported (2.3%, n=377). Concomitant vaccination was not associated with higher adverse event rates (RR 1.05, 95% CI 0.93 to 1.18). Rates of medical attendance were low (0.3%) with no safety signals identified. Supplementary opt-in survey data on later onset adverse events did not identify any difference in AEFI rates between those with and without underlying medical conditions. CONCLUSIONS: ZVL has a very good safety profile in the first week after vaccination in older adults. Active, participant-based surveillance in

BACKGROUND: Invasive Group A Streptococcal (iGAS) disease exerts an important burden among Australian children. No Australian hospitalisation cost estimates for treating children with iGAS disease exist, so the financial impact of this condition is unknown. AIM: To determine the minimum annual healthcare cost for children (< 18 years) hospitalised with iGAS disease in Australia from a healthcare sector perspective. METHODS: A cost analysis including children with laboratory-confirmed iGAS disease hospitalised at the Royal Children's Hospital (Victoria, Australia; July 2016 to June 2019) was performed. Results were extrapolated against the national minimum iGAS disease incidence. This analysis included healthcare cost from the 7 days prior to the index admission via General Practitioner (GP) and Emergency Department (ED) consultations; the index admission itself; and the 6 months post index admission via rehabilitation admissions, acute re-admissions and outpatient consultations. Additional extrapolations of national cost data by age group, Aboriginal and Torres Strait Islander ethnicity and jurisdiction were performed. RESULTS: Of the 65 included children, 35% (n = 23) were female, 5% (n = 3) were Aboriginal and Torres Strait Islander, and the average age was 4.4 years (SD 4.6; 65% aged 0-4). The iGAS disease related healthcare cost per child was $67,799 (SD $92,410). These costs were distributed across the 7 days prior to the index admission via GP and ED consultations (0.2 and 1.1% of total costs, respectively), the index admission itself (88.7% of the total costs); and the 6 months post index admission via rehabilitation admissions, acute re-admissions and outpatient consultations (5.3, 4.5 and 0.1% of total costs, respectively). Based on a national minimum paediatric incidence estimation of 1.63 per 100,000 children aged < 18 (95%CI: 1.11-2.32), the total annual healthcare cost for children with iGAS in 2019 was $6,200,862. The financial burden reflects the over

BACKGROUND: There are limited data in pediatric populations evaluating whether chronic cardiorespiratory conditions are associated with increased risk of coronavirus disease 2019 (COVID-19). We aimed to compare the rates of chronic cardiac and respiratory disease in children testing positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2[+]) compared with those testing negative (SARS-CoV-2[-]) at our institution. METHOD: Prospective cohort with nested case-control study of all children tested by polymerase chain reaction (PCR) for SARS-CoV-2 by nasopharyngeal/oropharyngeal sampling between March and October 2020. Children were identified prospectively via laboratory notification with age and sex-matching of SARS-CoV-2[+] to SARS-CoV-2[-] (1:2). Clinical data were extracted from the electronic medical record. RESULTS: In total, 179 SARS-CoV-2[+] children (44% females, median age 3.5 years, range: 0.1-19.0 years) were matched to 391 SARS-CoV-2[-] children (42% female, median age 3.7 years, range: 0.1-18.3 years). The commonest comorbidities showed similar frequencies in the SARS-CoV-2[+] and [-] groups: asthma (n = 9, 5% vs. n = 17, 4.4%, p = 0.71), congenital heart disease (n = 6, 3.4% vs. n = 7, 1.8%, p = 0.25) and obstructive sleep apnoea (n = 4, 2.2% vs. n = 10, 2.3%, p = 0.82). In the SARS-CoV-2[+] group, the prevalence of symptomatic disease was similar among children with and without cardiorespiratory comorbidities (n = 12, 75% vs. n = 103, 57%, p = 0.35). A high proportion of children hospitalized with SARS-CoV-2 infection had cardiac comorbidities (23.8%). CONCLUSIONS: In this single site data set, rates of pre-existing cardiorespiratory disease were similar in SARS-CoV-2[+] and SARS-CoV-2[-] children. Rates of symptomatic infection were similar between children with and without cardiorespiratory comorbidity. High rates of comorbid cardiac disease were observed among hospitalized children with COVID-19 warranting further research to inform vaccin

Paradoxical reactions in central nervous system tuberculosis (CNS-TB) are associated with significant morbidity and mortality. We describe 4 HIV-uninfected children treated for CNS-TB with severe paradoxical reactions unresponsive to corticosteroids. All made recovery after treatment with infliximab, highlighting the safety and effectiveness of infliximab for this complication, and need for prospective trials.

AIM: To describe the epidemiology of respiratory viruses in children before and during the 2020 SARS-CoV-2 pandemic and the relationship to public health measures instituted by the Victorian government. METHODS: Retrospective audit of respiratory viruses at a tertiary paediatric hospital in Melbourne from January 2015 up to week 47, 2020 in children under 18 years of age. The proportion of positive cases in weeks 1-47 in 2015-2019 (period 1) were compared to weeks 1-47, 2020 (period 2), and reviewed in the context of public health restrictions in Victoria. RESULTS: An annual average of 4636 tests were performed in period 1 compared to 3659 tests in period 2. Proportions of positive influenza A virus, influenza B virus, respiratory syncytial virus (RSV) and human parainfluenza virus were significantly reduced in period 2 compared to period 1: 77.3, 89.4, 68.6 and 66.9% reductions, respectively (all P < 0.001). From week 12-47, 2020, 28 893 SARS-CoV-2 tests were performed with a 0.64% positivity rate. Influenza viruses were not detected after week 17, RSV was not detected after week 35. CONCLUSIONS: Strict public health measures and border closures were successful in eliminating community transmission of SARS-CoV-2 in Melbourne. This was associated with a significant reduction in other respiratory virus infections in children. Identifying sustainable and effective ongoing public health interventions to reduce transmission of RSV and influenza could result in reduced morbidity and mortality in children and requires further research.

Children have lower hospitalisation and mortality rates for coronavirus disease-2019 (COVID-19) than adults; however, younger children (<4 years of age) 1 may develop more severe disease than older children. To date, the immune correlates of severe COVID-19 in young children have been poorly characterized. We report the kinetics of immune responses in relation to clinical and virological features in an infant with acute severe COVID-19. Systemic cellular and cytokine profiling showed initial increase in neutrophils and monocytes with depletion of lymphoid cell populations (particularly CD8+ T and NK cells) and elevated inflammatory cytokines. Expansion of memory CD4+T (but not CD8+T) cells occurred over time, with predominant Th2 bias. Marked activation of T cell populations observed during the acute infection gradually resolved as the child recovered. Significant in vitro activation of T-cell populations and robust cytokine production, in response to inactivated SARS-CoV-2 stimulation, was observed 3 months after infection indicating durable, long-lived cellular immune memory.

INTRODUCTION: There is a long-standing undersupply of nursing and allied health professionals in rural Australia. Rural, mature-aged people form an untapped section of rural communities that could help to address these workforce needs. There is little understanding of the supports required to assist rural, mature-aged nursing and allied health students to complete their studies and enter the rural health workforce. OBJECTIVE: To scope factors influencing rural, mature-aged nursing and allied health students' ability to access, participate, and succeed in higher education. DESIGN: A scoping review of the international rural nursing and allied health and education literature was undertaken. Five databases (CINAHL Complete, MEDLINE, Education Resources Information Center [ERIC], Embase, and Education Research Complete), key peer-reviewed journals, and Australian grey literature were searched. FINDINGS: Fourteen articles were included in the review. Ten studies described rural, mature-aged nursing and allied health student characteristics, 6 described barriers to students participating and succeeding in higher education, and 4 described student supports. DISCUSSION: This review found limited evidence to guide higher education providers in attracting, supporting and retaining rural, mature-aged nursing and allied health students. In particular, evidence of student supports is required beyond those manifested by students themselves or their family, to include offerings from university and government sources. CONCLUSION: Substantially more research attention is needed to understand the experiences of rural, mature-aged nursing and allied health students, and supports required for this cohort to access, participate and successfully complete higher education.

Xylazine produced significantly higher respiratory frequency, airway pressures, airway resistance and arterial carbon dioxide (CO2), and lower dynamic compliance, tidal volume, CO2 elimination and end tidal CO2 tension and arterial oxygen tension than medetomidine. This was associated with a significantly lower % of aerated tissue and higher % poorly and non-aerated tissue in CT images of sheep receiving xylazine versus medetomidine. In conclusion, xylazine administration produced marked decreases in pulmonary function, in ventilated isoflurane anaesthetized sheep, when compared to an equipotent dose of medetomidine when administered as an intravenous bolus supporting the use of medetomidine when alpha2-agonists are required.

Purpose Febrile seizures (FSs) occur in 3-5% of children under 6 years of age, with peak incidence in the second year of life. This coincides with the timing of the first dose of measles-containing vaccine in the United States, which has been shown to have a two-fold increased risk of FS in the two weeks following vaccination. Whole-cell pertussis and some influenza vaccines in combination with pneumococcal vaccines have also been associated with an increased rate of FSs when fever peaks after vaccination. Concerns about potential adverse neurocognitive outcomes following a vaccine proximate febrile seizure (VP-FS) can affect public and immunisation provider confidence in vaccine safety and impact on receipt of further vaccines. In this study, we compared the developmental and behavioural outcomes of children who have experienced an initial VP-FS to children who have had a non-vaccine proximate FS (NVP-FS) and to healthy controls who have not had a seizure. Methods This first ever prospective case-control study was conducted across four tertiary paediatric hospitals. Children who had their first FS before 30 months of age between May 2013 and April 2016 were recruited. They were either recruited as a VP-FS case, defined as a FS occurring on day 0-2 following receipt of an inactivated vaccine, day 5-14 following a live-attenuated vaccine or day 0-14 following a combination of inactivated and live-attenuated vaccines or an NVP-FS participant, defined as a FS outside of this period. Similar aged children with no history of seizures were recruited as controls. The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) was administered to all FS participants 12-24 months following their initial FS and controls of similar age to VP-FS cases at the time of their assessment. Pre-academic skills of children were assessed using Woodcock-Johnson Tests of Achievement, Third Edition. Parents rated their child's behaviour and executive functioning using Behav

Background: Invasive group A streptococcal disease is a severe infection with a high case fatality rate, estimated to cause more than 150,000 deaths per year worldwide. The clinical presentation of this infection is variable, and early diagnosis can be challenging. There are few data on its short-and longer-term outcomes, especially in children. The aim of this study was to assess the clinical presentation, management and short-and longer-term outcomes of invasive group A streptococcal disease in children in Australia. Method(s): We undertook a prospective surveillance study of children with laboratory-confirmed invasive group A streptococcus disease admitted to 7 sentinel tertiary and quaternary pediatric hospitals in Australia between July 2016 and June 2018. We collected demographic and clinical data and contacted patients 6 months after discharge to assess longer-term outcomes. Result(s): We enrolled 181 children, 7 days to 16 years of age. The principal site of invasive infection was blood (126 children, 69.6%), and the most frequent clinical presentation was pneumonia in 46 children (25.4%). Twenty-six children developed streptococcal toxic shock syndrome (14.4%), and 74 had severe disease (40.9%), including 71 admitted to the intensive care unit. Five children died (2.8%). At discharge and 6 months, 29.3% and 15.2% of the children had persisting health problems, respectively. Conclusion(s): Invasive group A streptococcal infection in Australian children is frequently severe and has a high long-term morbidity burden, highlighting the need for strengthened clinical care pathways, epidemiologic surveillance and prevention strategies.Copyright © 2019 Wolters Kluwer Health, Inc.

BACKGROUND: The Bacillus Calmette-Guerin (BCG) vaccine has an important role mitigating tuberculosis (TB) disease in high risk children. In Victoria, immunisation services at the Royal Children's Hospital (RCH) and Monash Health (MH) have been funded as the major providers of BCG vaccine since 2013. METHOD(S): In this article, we performed retrospective analysis of patients who attended RCH and MH for BCG between 1st November 2013- 30th November 2015. This was compared with local birth data in order to portray the distribution of BCG vaccine across various cohorts. OUTCOME(S): A total of 3,975 patients received BCG vaccine (1,775 at Monash, 2,200 from RCH). Detailed data is only available on 830 RCH patients. The median age of the study population was 6.9 months (IQR 3.9-11.3). The majority of children (98.9%, 2,575/2,604) received BCG vaccine prior to overseas travel. Of these, 96.0% (2,474/2,575) were travelling to countries in Asia. Only 13/2,604 (0.5%) were given BCG vaccine prior to travel to a country with low incidence of TB. Most infants were of Asian descent (93.3% mothers [2,425/2,604], 90.4% [2,346/2,604] fathers). A much smaller proportion was African (1.4% mothers [35/2,604], 1.5% [39/2,604] fathers). This contrasts with 2012 Victorian birth data, which showed that 82.2% (7,508/ 9,134) babies born to mothers from high TB prevalence countries were of Asian descent, whereas 8.9% (816/ 9,134) were of African descent. These results highlight scope to improve awareness and equity of BCG vaccine service, particularly to infants of African background.Copyright This work is copyright.

ObjectiveTo compare the developmental and behavioral outcomes of children experiencing an initial vaccine-proximate (VP) febrile seizure (FS) to those having a non-VP-FS (NVP-FS) and controls who have not had a seizure.MethodsIn this prospective multicenter cohort study, children with their first FS before 30 months of age between May 2013 and April 2016 were recruited from 4 Australian pediatric hospitals and classified as having VP-FS or NVP-FS. Similar-aged children with no seizure history were recruited as controls. The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) was administered to participants with FS 12 to 24 months after their initial FS and to controls 12 to 42 months of age at the time of assessment. The primary outcome was the Bayley-III cognitive score. Children's preacademic skills were assessed with the Woodcock-Johnson Tests of Achievement, Third Edition, and their behavior and executive functioning were obtained from parent questionnaires.ResultsThere was no significant difference in cognitive function between children with VP-FS (n = 62), those with NVP-FS (n = 70), and controls (n = 90) (F2,219 = 2.645, p = 0.07). There were no differences between the groups for all other measures and no increased risk of borderline/significant impairment or behavior in the clinical range in children with VP-FS compared to those with NVP-FS or controls.ConclusionVP-FS was not associated with an increased risk of developmental or behavioral problems in young children compared to children with NVP-FS or controls. Parents and providers should be reassured by the absence of adverse effects of VP-FS on the development of children.Copyright © American Academy of Neurology.

We provide an update on the state of play with regards a newly described inflammatory condition which has arisen during the current SARS-CoV-2 pandemic. The condition has been named paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 or multisystem inflammatory syndrome in children. This condition has shown significant similarities to Kawasaki disease and toxic shock syndrome.

Compared to adults, children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have mild or asymptomatic infection, but the underlying immunological differences remain unclear. We describe clinical features, virology, longitudinal cellular and cytokine immune profile, SARS-CoV-2-specific serology and salivary antibody responses in a family of two parents with PCR-confirmed symptomatic SARS-CoV-2 infection and their three children, who were repeatedly SARS-CoV-2 PCR negative. Cellular immune profiles and cytokine responses of all children were similar to their parents at all timepoints. All family members had salivary anti-SARS-CoV-2 antibodies detected, predominantly IgA, that coincided with symptom resolution in 3 of 4 symptomatic members. Plasma from both parents and one child had IgG antibody detected against the S1 protein and virus neutralising activity ranging from just detectable to robust titers. Using a systems serology approach, we show that all family members demonstrated higher levels of SARS-CoV-2-specific antibody features than healthy controls. These data indicate that children can mount an immune response to SARS-CoV-2 without virological evidence of infection. This raises the possibility that despite chronic exposure, immunity in children prevents establishment of SARS-CoV-2 infection. Relying on routine virological and serological testing may therefore not identify exposed children, with implications for epidemiological and clinical studies across the life-span.

BACKGROUND: The lack of a uniform surveillance case definition poses a challenge to characterize the epidemiology, clinical features, and disease burden of the respiratory syncytial virus (RSV). Global standards for RSV surveillance will inform immunization policy when RSV vaccines become available. METHODS: The WHO RSV surveillance pilot leverages the capacities of the Global Influenza Surveillance and Response System (GISRS). Hospitalized and non-hospitalized medically attended patients of any age were tested for RSV using standardized molecular diagnostics throughout the year in fourteen countries. An extended severe acute respiratory infection (extended SARI) or an acute respiratory infection (ARI) case definition was used that did not require fever as a criterion. RESULTS: Amongst 21 221 patients tested for RSV between January 2017 and September 2018, 15 428 (73%) were hospital admissions. Amongst hospitalized RSV-positive patients, 50% were aged <6 months and 88% <2 years. The percentage of patients testing positive for RSV was 37% in children <6 months and 25% in those aged 6 months to 2 years. Patients with fever were less likely to be RSV positive compared to those without fever (OR 0.74; 95% CI: 0.63-0.86). For infants <6 months, 29% of RSV ARI cases did not have fever. CONCLUSION: Requiring fever in a case definition for RSV lowers the sensitivity to detect cases in young children. Countries should consider ways to leverage the GISRS platform to implement RSV surveillance with an augmented case definition amongst the young pediatric population.

Background: SAEFVIC is the Victorian surveillance system for adverse events following immunisation (AEFI). It enhances passive surveillance by also providing clinical support and education to vaccinees and immunisation providers. This report summarises surveillance, clinical and vaccine pharmacovigilance activities of SAEFVIC in 2018. Methods: A retrospective observational cohort study of AEFI reports received by SAEFVIC in 2018, compared with previous years since 2008. Data were categorised by vaccinee demographics of age, sex, pregnancy and Indigenous status, vaccines administered and AEFI reactions reported. Age cohorts were defined as infant (0-12 months); young child (1-4 years); school-aged (5-17 years); adult (18-64 years); and older person (65+ years). Proportional reporting ratios were calculated for signal investigation of serious adverse neurological events with all vaccines and with influenza vaccines. Clinical support services and educational activities are described. Results: SAEFVIC received 1730 AEFI reports (26.8 per 100,000 population), with 9.3% considered serious. Nineteen percent (n = 329) attended clinical review. Annual AEFI reporting trends increased for infants, children and older persons, but were stable for school-aged and adult cohorts. Females comprised 55% of all reports and over 80% of reports among adults. There were 17 reports of AEFI in pregnant women and 12 (0.7%) in persons identifying as Indigenous Australians. A possible signal regarding serious adverse neurological events (SANE) was detected, but was not supported by signal validation testing. A clinical investigation is ongoing. Two deaths were reported coincident to immunisation with no evidence of causal association. Conclusion: SAEFVIC continues to provide robust AEFI surveillance supporting vaccine safety monitoring in Victoria and Australia, with new signal detection and validation methodologies strengthening capabilities.

BACKGROUND: Febrile seizures (FSs) are a common pediatric condition caused by a sudden rise in temperature, affecting 3% to 5% of children aged #6 years. Although vaccination can cause FSs, little is known on whether FSs occurring in the time soon after vaccination (vaccine-proximate febrile seizures [VP-FSs] differ clinically from non-vaccine-proximate febrile seizures [NVP-FSs]). We compared the clinical profile and outcomes of VP-FS to NVP-FS. METHOD(S): Prospective cohort study of children aged #6 years presenting with their first FS at 1 of 5 Australian pediatric hospitals between May 2013 and June 2014. Clinical features, management, and outcomes were compared between VP-FS and NVP-FS. RESULT(S): Of 1022 first FS cases (median age 19.8 months; interquartile range 13.6-27.6), 67 (6%) were VP-FSs. When comparing VP-FS to NVP-FS, there was no increased risk of prolonged (.1 day) hospitalization (odds ratio [OR] 1.61; 95% confidence interval [95% CI] 0.84-3.10), ICU admission (OR 0.72; 95% CI 0.10-5.48), seizure duration .15 minutes (OR 1.47; 95% CI 0.73-2.98), repeat FS within 24 hours (OR 0.80; 95% CI 0.34-1.89), or requirement for antiepileptic treatment on discharge (OR 1.81; 95% CI 0.41-8.02). VP-FS patients with a laboratory-confirmed infection (12%) were more likely to have a prolonged admission compared with those without. CONCLUSION(S): VP-FS accounted for a small proportion of all FS hospital presentations. There was no difference in outcomes of VP-FS compared with NVP-FS. This is reassuring data for clinicians and parents of children who experience FS after vaccination and can help guide decisions on revaccination.Copyright © 2019 by the American Academy of Pediatrics.

Background. Invasive group A Streptococcus (GAS) disease has an incidence in high-income countries of 3 to 5 per 100 000 per annum and a case-fatality ratio of 10% to 15%. Although these rates are comparable to those of invasive meningococcal disease in Australia before vaccine introduction, invasive GAS disease currently requires reporting in only 2 jurisdictions. Methods. Data were collected prospectively through active surveillance at the Royal Children's Hospital, Melbourne (October 2014 to September 2016). Isolation of GAS from a sterile site was required for inclusion. Comprehensive demographic and clinical data were collected, and emm typing was performed on all isolates. Disease was considered severe if the patient required inotropic support or mechanical ventilation. Results. We recruited 28 patients. The median age of the patients was 3.5 years (range, 4 days to 11 years). Ten (36%) patients had severe disease. Fifteen (54%) children had presented to a medical practitioner for review in the 48 hours before their eventual admission, including 7 of the 10 patients with severe GAS infection. Complications 6 months after discharge persisted in 21% of the patients. emm1 was the most common emm type (29%). Conclusion. We found considerable short- and longer-term morbidity associated with pediatric invasive GAS disease in our study. Disease manifestations were frequently severe, and more than one-third of the patients required cardiorespiratory support. More than one-half of the patients attended a medical practitioner for assessment but were discharged in the 48-hour period before admission, which suggests that there might have been a window for earlier diagnosis. Our methodology was easy to implement as a surveillance system.Copyright © The Author(s) 2017.

The Influenza Complications Alert Network (FluCAN) is a sentinel hospital-based surveillance program that operates at sites in all jurisdictions in Australia. This report summarises the epidemiology of hospitalisations with laboratory-confirmed influenza during the 2018 influenza season. In this observational surveillance system, cases were defined as patients admitted to any of the 17 sentinel hospitals with influenza confirmed by nucleic acid detection. Data were also collected on a frequency-matched control group of influenza-negative patients admitted with acute respiratory infection. During the period 3 April to 31 October 2018 (the 2018 influenza season), 769 patients were admitted with confirmed influenza to one of 17 FluCAN sentinel hospitals. Of these, 30% were elderly (>=65 years), 28% were children (<16 years), 6.4% were Aboriginal and Torres Strait Islander peoples, 2.2% were pregnant and 66% had chronic comorbidities. A small proportion of FluCAN admissions were due to influenza B (13%). Estimated vaccine coverage was 77% in the elderly (>=65 years), 45% in non-elderly adults with medical comorbidities and 26% in children (<16 years) with medical comorbidities. The estimated vaccine effectiveness (VE) in the target population was 52% (95% CI: 37%, 63%). There were a smaller number of hospital admissions detected with confirmed influenza in this national observational surveillance system in 2018 than in 2017, with the demographic profile reflecting the change in circulating subtype from A/H3N2 to A/H1N1.Copyright © Commonwealth of Australia CC BY-NC-ND.

Background In 2017, Australia experienced record influenza notifications. Two surveillance programs combined to summarize the epidemiology of hospitalized influenza in children and report on vaccine effectiveness (VE) in the context of a limited nationally funded vaccination program. Methods Subjects were prospectively recruited (April-October 2017). Case patients were children aged <=16 years admitted to 11 hospitals with an acute respiratory illness and laboratory-confirmed influenza. Controls were hospitalized with acute respiratory illness and tested negative for influenza. VE estimates were calculated using the test-negative design. Results A total of 1268 children were hospitalized with influenza: 31.5% were <2 years old, 8.3% were indigenous, and 45.1% had comorbid conditions predisposing to severe influenza. Influenza B was detected in 34.1% with influenza A/H1N1 and A/H3N2 detected in 47.2% and 52.8% of subtyped influenza A specimens. The median length of stay was 3 days (interquartile range, 1-5), 14.5% were admitted to the intensive care unit, and 15.9% received oseltamivir. Four in-hospital deaths occurred (0.3%): one was considered influenza associated. Only 17.1% of test-negative-controls were vaccinated. The VE of inactivated quadrivalent influenza vaccine for preventing hospitalized influenza was estimated at 30.3% (95% confidence interval, 2.6%-50.2%). Conclusions Significant influenza-associated morbidity was observed in 2017 in Australia. Most hospitalized children had no comorbid conditions. Vaccine coverage and antiviral use was inadequate. Influenza vaccine was protective in 2017, yet VE was lower than previous seasons. Multiple Australian states have introduced funded preschool vaccination programs in 2018. Additional efforts to promote vaccination and monitor effectiveness are required.Copyright © The Author(s) 2018. Published by Oxford University Press for the Infectious Diseases Society of America.

Students in enabling programs bring richness, diversity, and complexity to the teaching and learning environment. They are often from under-represented backgrounds, have experienced educational disadvantage or disruption, belong to multiple equity groups, and face academic and non-academic challenges, including mental ill-health. This pilot study explored academic staff experiences in teaching and supporting students in enabling programs. Using a collaborative autoethnographical approach, four members of a multi-institutional research group wrote first-person reflections in response to guiding questions. From generative and reflective discussions, different themes arose. A major theme was the high ‘emotional labour demands’ of teaching a vulnerable cohort, with both positive and negative effects on staff. Other major themes included: the diversity of emotional responses and coping strategies; the complex, sometimes contradictory, role of the enabling educator; the importance of communities of care and support; and the impact of witnessing students’ transformations. Within these themes, the challenges, rewards, and protective factors, which mitigate stress among enabling educators, were identified.

Australia was alerted to a possible increase in allergyrelated adverse events following immunisation (AEFI) with 2015 seasonal trivalent influenza vaccines (TIV) by the Victorian state vaccine safety service, SAEFVIC. We describe SAEFVIC's initial investigation and upon conclusion of the 2015 influenza vaccination programme, to define the signal event and implications for vaccine programmes. Allergy-related AEFI were defined as anaphylaxis, angioedema, urticaria or generalised allergic reaction. Investigations compared 2015 TIV AEFI reports to previous years as proportions and reporting risk (RR) per 100,000, stratified by influenza vaccine brand. The initial investigation showed an increased proportion of allergy-related AEFI compared with 2014 (25% vs 12%), predominantly in adults, with insufficient clinical severity to alter the programme risk-benefit. While overall TIV AEFI RR in 2015 was similar to previous years (RR: 1.07, 95% confidence interval (CI): 0.88-1.29), we identified a near-doubling RR for allergy-related AEFI in 2015 (RR: 1.78, 95% CI: 1.14- 2.80) from 2011 to 2014 with no difference by vaccine brand or severity increase identified. This increase in generalised allergy-related AEFI, across all used vaccine brands, supports evidence of variable reactogenicity arising from influenza vaccine strain variations. This investigation underlines the importance of effective seasonal influenza vaccine pharmacovigilance.Copyright © 2017 European Centre for Disease Prevention and Control (ECDC).

IMPORTANCE: Incorporating combination vaccines, such as the measles-mumps-rubella-varicella (MMRV) vaccine, into immunization schedules should be evaluated from a benefit-risk perspective. Use of MMRV vaccine poses challenges due to a recognized increased risk of febrile seizures (FSs) when used as the first dose in the second year of life. Conversely, completion by age 2 years of measles, mumps, rubella, and varicella immunization may offer improved disease control. OBJECTIVE: To evaluate the effect on safety and coverage of earlier (age 18 months) scheduling of MMRV vaccine as the second dose of measles-containing vaccine (MCV) in Australia. DESIGN, SETTING, AND PARTICIPANTS: Prospective active sentinel safety surveillance comparing the relative incidence (RI) of FSs in toddlers given MMRV and measles-mumps-rubella (MMR) and a national cohort study of vaccine coverage rates and timeliness before and after MMRV vaccine introduction were conducted. All Australian children aged 11 to 72 months were included in the coverage analysis, and 1471 Australian children aged 11 to 59 months were included in the FS analysis, with a focus on those aged 11 to 23 months. MAIN OUTCOMES AND MEASURES: MMRV vaccine safety, specifically, the RI of FSs after MMRV vaccine at age 18 months, compared with risk following MMR vaccine and vaccine uptake for 2-dose MCV and single-dose varicella vaccine, focusing on timeliness. RESULTS: Of the 1471 children, the median age at first FS was 21 months (interquartile range [IQR], 14-31 months). Three hundred ninety-one children were aged 11 to 23 months and had at least 1 FS included in the analysis; of these, 207 (52.9%) were male. A total of 278 children (71.1%) had received MMR followed by MMRV vaccine, 97 (24.8%) had received MMR vaccine only, and 16 (4.1%) had received neither vaccine. There was no increased risk of FSs (RI, 1.08; 95% CI, 0.55-2.13) in the 5 to 12 days following MMRV vaccine given as the second MCV to toddlers. Febrile seizur
