Magnetic resonance imaging (MRI) scoring systems are used in the neonatal period to predict outcome in infants with neonatal encephalopathy. Our aim was to assess the relationship between three MRI scores and neurodevelopmental outcome assessed using Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), at two years in infants with neonatal encephalopathy.Term-born neonates with evidence of perinatal asphyxia born between 2011 and 2015 were retrospectively reviewed. MRI scanning was performed within the first two weeks of life and scored using Barkovich, National Institute of Child Health and Human Development (NICHD) Neonatal Research Network (NRN), and Weeke systems by a single assessor blinded to the infants clinical course. Neurodevelopmental outcome was assessed using composite scores on the Bayley-III at two years. Multiple linear regression analyses were used to assess the association between MRI scores and Bayley-III composite scores, with postmenstrual age at scan and sex included as covariates.Of the 135 recruited infants, 90 infants underwent MRI, and of these, 66 returned for follow-up. MRI abnormalities were detected with the highest frequency using the Weeke score (Barkovich 40%, NICHD NRN 50%, Weeke 77%). The inter-rater agreement was good for the Barkovich score and excellent for NICHD NRN and Weeke scores. There was a significant association between Barkovich, NICHD NRN, and Weeke scores and Bayley-III cognitive and motor scores. Only the Weeke score was associated with Bayley-III language scores.Our findings confirm the predictive value of existing MRI scoring systems for cognitive and motor outcome and suggest that more detailed scoring systems have predictive value for language outcome.

AIM Neonatal encephalopathy (NE) is associated with an increased risk of multi-organ injury. The lack of standardised definitions for multi-organ dysfunction in NE hinders accurate quantification of these complications. METHODS A simple multi-organ dysfunction in neonatal encephalopathy scoring (MODE) system was created to include the cardiovascular, respiratory, gastrointestinal, haematological and neurological systems with a maximum score of 15. The MODE score was then compared with the grade of NE, Bayley Scales of Infant Development (Bayley-III) at 2 years of age and mortality. The Bayley score was used as it gave an objective score making it easier to compare the MODE score. Bayley score of

Background:We aimed to characterise the impact of Down syndrome on myocardial performance and loading conditions in infants with Down syndrome and CHD over the peri-operative period by comparing them with infants matched for cardiac lesion with a normal microarray.Methods:Left ventricular global longitudinal strain, right ventricular free wall longitudinal strain, left ventricular end-systolic wall stress, and right ventricular systolic pressure were measured in the two groups over the peri-operative period.Results:Fifty-five infants had a diagnosis of Down syndrome and these were compared with 29 control infants. Left ventricular global longitudinal strain decreased in both groups post-operatively with the Down syndrome group demonstrating some recovery pre-discharge (18 ± 3 versus 16 ± 3 %, p = 0.01). Right ventricular longitudinal strain significantly decreased in both groups post-operatively with the control group demonstrating better recovery by hospital discharge (14 ± 4 versus 18 ± 6 %, p < 0.01). End-systolic wall stress was lower and right ventricular systolic pressure was higher in the Down syndrome group throughout the study period (all p < 0.05). Down syndrome was an independent predictor of the duration of ventilation, post-operative use of inotropes, and intensive care stay. Right ventricular longitudinal strain was an independent predictor of duration of intensive care stay.Conclusion:This study demonstrates the difference between the two groups in relation to left and right ventricular function, particularly prior to discharge, and outlines the additional impact a diagnosis of Down syndrome has on myocardial performance during the peri-operative period.

The management of sagittal craniosynostosis has evolved over the decades as teams seek to refine their surgical approaches to idealize head shape with the least possible morbidity. Here, the authors identify the incidence of raised intracranial pressure (ICP) and its risk factors, requiring secondary surgical intervention after cranial vault remodeling (CVR) procedure at a single tertiary referral craniofacial unit. A retrospective case-control study was performed on the patients with isolated non-syndromic sagittal craniosynostosis. All patients who underwent CVR in our unit and had a minimum of 1.5 years follow-up were included. One hundred and eighty-four patients (134 male and 50 female) who underwent primary CVR surgery for isolated sagittal craniosynostosis were included. Thirteen patients (7.07%) had clinical evidence of late raised ICP resulting in repeat CVR procedures. Higher incidence of raised ICP in patients who had primary surgery before 6 months than after or at 6 months of age (P = 0.001). There were 23.5%, 5.6%, 3.2%, and 1.9% of secondary raised ICP patients who underwent the primary surgery between 1999-2004, 2005-2010, 2011-2015 and 2016-2018, respectively (P = 0.024). The risk of secondary raised ICP was higher in patients with isolated sagittal craniosynostosis whose primary surgery occurred before the age of 6 months (two times more likely). More extensive CVR can be performed safely in sagittal synostosis with promising outcomes. The late presentation with raised ICP reinforces the importance of long-term multidisciplinary protocol-based follow-up.

AIM Neonatal encephalopathy (NE) is associated with altered cognitive, motor, sensory abilities and behavioural outcomes. This case-control study aimed to assess whether Quality of Life (QoL) and sleep disorders are affected in older children following NE compared to age-matched controls. METHODS Children at school-age post-NE were recruited and compared to age-matched controls. Sleep and QoL were assessed with the Pediatric Quality of Life Inventory and the Child Sleep Habit Questionnaire. RESULTS One hundred children were recruited with an age range of 4-6 years, including children post-NE (n=45) and age-matched controls (n = 55). Significantly higher pathological sleep scores were evident in 58% of children post-NE compared to controls (43.8 vs 40.2; p = 0.001). Children post-NE had increased bedtime resistance (p = 0.028) and sleep anxiety (p = 0.01) compared to controls. Children in the post-NE group had lower total QoL scores versus controls (mean score 82.5 vs 95.8; p

Objective To evaluate COVID-19 pandemic preparedness, available resources, and guidelines for neonatal care delivery among neonatal health care providers in low- and middle-income countries (LMICs) across all continents. Study design Cross-sectional, web-based survey administered between May and June, 2020. Results Of 189 invited participants in 69 LMICs, we received 145 (77%) responses from 58 (84%) countries. The pandemic provides significant challenges to neonatal care, particularly in low-income countries. Respondents noted exacerbations of preexisting shortages in staffing, equipment, and isolation capabilities. In Sub-Saharan Africa, 9/35 (26%) respondents noted increased mortality in non-COVID-19-infected infants. Clinical practices on cord clamping, isolation, and breastfeeding varied widely, often not in line with World Health Organization guidelines. Most respondents noted family access restrictions, and limited shared decision-making. Conclusions Many LMICs face an exacerbation of preexisting resource challenges for neonatal care during the pandemic. Variable approaches to care delivery and deviations from guidelines provide opportunities for international collaborative improvement.

BACKGROUND There is increasing recognition of adverse mental health consequences of preterm birth and the impact on social-emotional development. However, the quality of the developing parent-infant relationship may be protective, with enhanced maternal sensitivity to infants' cues associated with improved outcomes. METHODS Eighty mothers and their preterm infants born

AIM To examine pro- and anti-inflammatory cytokines in children with cerebral palsy (CP) at baseline and in response to endotoxin (lipopolysaccharide), and correlate outcomes compared with age-matched comparisons, to evaluate their ability to mount an immune response. METHOD Serum cytokines were assessed in 12 children (eight males, four females; mean age 10y 1mo [SD 1y 8mo], 6-16y) with CP against 12 age-matched comparisons (eight males, four females; mean age 9y 1mo [SD 1y 1mo]). Pro- and anti-inflammatory cytokines (interleukin-1β, interleukin-2, interleukin-6, interleukin-8, interleukin-10, interleukin-18, tumour necrosis factor [TNF]-α, TNF-β, interferon-γ, granulocyte-macrophage colony-stimulating factor [GM-CSF], vascular endothelial growth factor [VEGF], erythropoietin, and interleukin-1 receptor antagonist) were measured at baseline and in response to in vitro simulation with lipopolysaccharide by multiplex enzyme-linked immunosorbent assay. RESULTS Significantly higher erythropoietin was found at baseline in children with CP compared with the comparison group. There was a strong response to lipopolysaccharide for interleukin-8, VEGF, TNF-α, and GM-CSF in both children with CP and the comparison group; however, there was significant lipopolysaccharide hyporesponsiveness in children with CP compared with the comparison group for interleukin-1α, interleukin-1β, interleukin-2, and interleukin-6. INTERPRETATION Altered cytokine responses in children with CP compared with the comparison group demonstrate an altered inflammatory state that may contribute to ongoing sequelae and could be a target for therapy. WHAT THIS PAPER ADDS Altered inflammatory responses persist in children with cerebral palsy (CP). Erythropoietin is elevated in children with CP compared with the comparison group. Children with CP have reduced interleukin-1α, interleukin-1β, interleukin-2, and interleukin-6 inflammatory responses to lipopolysaccharide.

Cloverleaf skull deformity (CSD), or Kleeblattschadel, is a condition with severe and unpatterned multisuture craniosynostosis, resulting in a trilobar-shaped skull. This deformity mainly comprises a cranio-orbito-facial malformation that leads to a spectrum of multidisciplinary issues. Several syndromes are associated with CSD, such as Crouzon syndrome (CS). Here, we report the case of an infant with CS and the pathogenic c.1061C>G (p.Ser354Cys) variant of the fibroblast growth factor receptor 2 (FGFR2) gene. The child presented with the severe form of CSD despite having a normal, mid-trimester, sonographic scan.

Down Syndrome (DS) is the most common chromosomal abnormality of live born babies. Individuals with DS are at increased risk of cardiopulmonary morbidities in the early neonatal period, infancy and childhood that manifest with elevated pulmonary arterial pressures and altered myocardial performance. Pulmonary hypertension (PH) during the early neonatal period remains under-recognised in this population. PH may occur with or without a congenital heart defect in children with DS and is more common than in the general population. Early detection and continued screening of PH throughout infancy and childhood for these at-risk children is crucial for prompt intervention and potential prevention of long-term sequelae on cardiac function. This review summarises the main physiological concepts behind the mechanisms of PH in children with DS and provides a summary of the current available literature on PH and its impact on myocardial performance.

Aim To review multiorgan involvement and management in children with Down syndrome (DS). Methods A literature review of articles from 1980 to 2019 using the MEDLINE interface of PubMed was performed using the following search terms- [Down syndrome] or [Trisomy 21] AND [Cardiology] or [Respiratory] or [neurodevelopment] or [epilepsy] or [musculoskeletal] or [immune system] or [haematological] or [endocrine] or [gastrointestinal] or [ophthalmological] or [Ear Nose Throat] or [dermatology] or [renal]. Results Congenital heart disease particularly septal defects occur in over 60% of infants with DS and 5%-34% of infants develop persistent pulmonary hypertension of the newborn irrespective of a diagnosis of congenital heart disease. Early recognition and management of aspiration, obstructive sleep apnoea and recurrent lower respiratory tract infections (LRTI) could reduce risk of developing pulmonary hypertension in later childhood. Children with DS have an increased risk of autistic spectrum disorder, attention deficit disorder and epilepsy particularly infantile spasms, which are associated with poor neurodevelopmental outcomes. Congenital anomalies of the gastrointestinal and renal system as well as autoimmune diseases, coeliac disease, arthropathy, thyroid dysfunction fold diabetes mellitus and dermatological conditions are more common. Hearing and visual anomalies are also well recognised association with DS (Table 1). Conclusion Children with DS are at an increased risk of multiorgan comorbidities. Organ-specific health surveillance may provide holistic care for the children and families with DS throughout childhood.

Background Optimising physical distancing measures has been a critical part of the global response to the spread of COVID-19. Adherence to these recommendations has been poorer than adherence to other key transmission reduction behaviours. The current project aimed to identify psychosocial determinants of adherence to physical distancing, and to determine whether Government of Ireland COVID-19 communications adequately address the determinants. Methods A nationally representative cross-sectional survey as part of the International COVID-19 Awareness and Responses Evaluation (iCARE) study, a qualitative interview study, and a content analysis of COVID-19 poster communications were conducted to identify psychosocial determinants of adherence and determine the extent to which these were addressed in government communications. Results The iCARE survey showed adherence to physical distancing measures varies by sociodemographic group (e.g., age, sex, COVID-19 risk category) and beliefs. Poorest adherence was reported by younger people, males, those at lower risk of serious illness from COVID-19, and those who were less concerned about the impact of COVID-19 on public health and the economy. The qualitative interview study revealed maintaining and negotiating close relationships, public physical environments, habituation to threat, risk-taking to maintain wellbeing, and confusion and uncertainty around government guidelines as barriers to physical distancing behaviour. Having a sense of personal responsibility and control over one's own behaviour was identified as a potential facilitator of adherence to distancing. Content analysis revealed some important gaps, particularly in terms of rationale for specific public health guidelines. Conclusions Though adherence was high overall, there was variability among sociodemographic groups. Government communications to promote physical distancing could be refined to better address key barriers and facilitators of the behaviour.

Glial fibrillary acidic protein (GFAP) is a neuronal protein released after traumatic brain injury (TBI) and detectable in serum samples. GFAP correlates with symptom severity in adults and may be a marker of brain injury in children with milder symptoms or preverbal children.GFAP was examined in children with severe TBI (initial Glasgow Coma Scale score8), with mild TBI (Glasgow Coma Scale score 14/15), and at 0 to 4 and at 10 to 14 days after TBI and was compared with healthy age-matched controls. Mechanism, time points from injury, and symptoms were recorded.The study enrolled 208 children including 110 with TBI (n = 104 mild, 6 severe) and controls (n = 98). GFAP was higher in mild TBI than in controls and highest in the severe TBI cohort, with a maximum value at 6 hours from injury. Vomiting was significantly associated with higher GFAP levels, but no association was found with amnesia, loss of consciousness, and the Sports Concussion Assessment Tool. Children reporting1-point changes from their preinjury functioning on the Post-Concussive Symptom Inventory had higher initial GFAP but not total Post-Concussive Symptom Inventory score changes.GFAP identifies children with TBI, even at the milder end of the spectrum, and is strongly associated with postinjury vomiting. It may be a useful marker of pediatric TBI; however, sampling is time critical.

ObjectivesThis systematic review aimed to describe medication non-adherence among people living with multimorbidity according to the current literature, and synthesise predictors of non-adherence in this population.MethodsA systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses. PubMed, EMBASE, CINAHL and PsycINFO were searched for relevant articles published in English language between January 2009 and April 2019. Quantitative studies reporting medication non-adherence and/or predictors of non-adherence among people with two or more chronic conditions were included in the review. A meta-analysis was conducted with a subgroup of studies that used an inclusive definition of multimorbidity to recruit participants, rather than seeking people with specific conditions. Remaining studies reporting prevalence and predictors of non-adherence were narratively synthesised.ResultsThe database search produced 10 998 records and a further 75 were identified through other sources. Following full-text screening, 178 studies were included in the review. The range of reported non-adherence differed by measurement method, at 76.5% for self-report, 69.4% for pharmacy data, and 44.1% for electronic monitoring. A meta-analysis was conducted with eight studies (n=8949) that used an inclusive definition of multimorbidity to recruit participants. The pooled prevalence of non-adherence was 42.6% (95% CI: 34.0 - 51.3%, k=8, I2=97%, pConclusionsThe review identified a heterogeneous literature in terms of conditions studied, and definitions and measures of non-adherence used. Results suggest that future attempts to improve adherence among people with multimorbidity should determine for which conditions individuals require most support. The variable levels of medication non-adherence highlight the need for more attention to be paid by healthcare providers to the impact of multimorbidity on chronic disease self-management.PROSPERO registration numberCRD42019133849.

Background: Evidence suggests that earlier diagnosis and initiation of treatment immediately after birth is critical for improved neurodevelopmental outcomes following neonatal encephalopathy (NE). Current diagnostic tests are, however, mainly restricted to clinical diagnosis with no molecular tests available. Purines including adenosine are released during brain injury such as hypoxia and are also present in biofluids. Whether blood purine changes can be used to diagnose NE has not been investigated to date.Methods: Blood purines were measured in a mouse model of neonatal hypoxia and infants with NE using a novel point-of-care diagnostic technology (SMARTChip) based on the summated electrochemical detection of adenosine and adenosine metabolites in the blood.Results: Blood purine concentrations were ∼2–3-fold elevated following hypoxia in mice [2.77 ± 0.48 μM (Control) vs. 7.57 ± 1.41 μM (post-hypoxia), p = 0.029]. Data in infants with NE had a 2–3-fold elevation when compared to healthy controls [1.63 ± 0.47 μM (Control, N = 5) vs. 4.87 ± 0.92 μM (NE, N = 21), p = 0.0155]. ROC curve analysis demonstrates a high sensitivity (81%) and specificity (80%) for our approach to identify infants with NE. Moreover, blood purine concentrations were higher in infants with NE and seizures [8.13 ± 3.23 μM (with seizures, N = 5) vs. 3.86 ± 0.56 μM (without seizures, N = 16), p = 0.044].Conclusion: Our data provides the proof-of-concept that measurement of blood purine concentrations via SMARTChip technology may offer a low-volume bedside test to support a rapid diagnosis of NE.

Background Young adults with asthma often report low adherence to inhaled corticosteroids (ICS), leading to uncontrolled symptoms and poor disease outcomes. Technology-enabled digital supports such as mobile health (mHealth) asthma smartphone apps have the potential to support adherence to ICS and asthma self-management. There is a need for feasibility studies to determine the usability, acceptability, and feasibility of these interventions. In addition, it is essential to determine the feasibility of recruiting and retaining young adults to plan future efficacy and effectiveness trials and therefore, establish evidence-based asthma apps. Objective This study aimed to determine (1) the feasibility of recruiting and retaining young adults to a trial and (2) the usability, acceptability, and feasibility of using the AsthmaMD app to support adherence to ICS in a population of young adults living with asthma. Methods A multi-methods feasibility study was conducted. Young adults aged 18-30 years with asthma and current prescription for ICS were eligible and invited to take part through a university circular email, social media, and general practice sites. Participation involved completing a baseline self-report questionnaire, downloading and using the AsthmaMD app for 2 weeks, and completing the follow-up assessment, including self-report and open-ended questions about participants’ experience of using the app. Primary outcomes included participant recruitment and retention and the usability, acceptability, and feasibility of using AsthmaMD. Quantitative self-report data were analyzed using descriptive statistics, and qualitative open-ended data were analyzed using inductive reflexive thematic analysis. Results A total of 122 young adults (females, n=101, 82.8%) with a mean age of 24.4 (SD 3.8) years were recruited and they completed baseline measures. Of the 122 young adults, 59 (48.4%) completed the study. The AsthmaMD app received a mean score of 63.1/100 (SD 20.1) on the System Usability Scale (ie, a standardized measure of usability for technology-based apps), and an overall user satisfaction score of 5.8/10 (SD 2.2). Of the 59 participants who completed the study, 49 (83%) participants used the app ≥1 day per week. Two main themes were identified in the qualitative analysis of user experiences: (1) learning how to use the app to suit the individual and (2) benefits and relevance of using the app. Conclusions The findings from this study indicate that it is feasible to recruit and retain young adults to examine efficacy and effectiveness in a future trial and that young adults living with asthma may find AsthmaMD to be usable, acceptable, and feasible to support adherence to ICS. Our findings also identified opportunities to further optimize the usability of AsthmaMD and similar apps. Based on our findings, we recommend providing more accessible information on how to use the app and replacing medical terminology with simplified language within the app to improve usability.

Objective Compared to single diseases, health psychology reflects many areas of medical research by affording relatively less attention to the experiences of people self-managing multiple co-occurring conditions and, in particular, the experience of managing the associated complex medication regimens. This study aimed to explore the experience of self-managing multimorbidity among older adults, with a focus on medication adherence. Design A qualitative approach was taken, using individual semi-structured interviews. Methods Sixteen people with complex multimorbidity aged 65 years or older were recruited through general practice to take part in semi-structured interviews. Data were analysed following guidelines for reflexive thematic analysis. Results Two themes were generated, with each theme comprising three subthemes. Theme one represents the amplified burden arising from multimorbidity that leads to unique challenges for self-management, such as integrating multiple medications into daily life, accumulating new symptoms and treatments, and managing evolving medication regimens. Theme two represents pathways towards relief that reduce this burden and promote medication adherence, such as prioritising certain conditions and treatments, resigning to the need for multiple medications, and identifying and utilising adherence supports. Conclusions We identified factors relevant to medication adherence for older adults with multimorbidity that go beyond single-disease influences and account for the amplified experience of chronic disease that multimorbidity can produce for some people. While evidence of single-disease influences remains fundamental to tailoring behavioural interventions to individuals, the impact of multimorbidity on medication adherence should be accounted for in research and practice.

Neonatal encephalopathy (NE) describes the clinical syndrome of a newborn with abnormal brain function that may result from a variety of etiologies. HIE should be distinguished from neonatal encephalopathy due to other causes using data gathered from the history, physical and neurological exam, and further investigations. Identifying the underlying cause of encephalopathy has important treatment implications. This review outlines conditions that cause NE and may be mistaken for HIE, along with their distinguishing clinical features, pathophysiology, investigations, and treatments. NE due to brain malformations, vascular causes, neuromuscular causes, genetic conditions, neurogenetic disorders and inborn errors of metabolism, central nervous system (CNS) and systemic infections, and toxic/metabolic disturbances are discussed.

OBJECTIVESResearchers in recent studies suggest that hospitalized febrile infants aged ≤60 days may be safely discharged if bacterial cultures are negative after 24–36 hours of incubation. We aimed to describe trends and variation in length of stay (LOS) for hospitalized febrile infants across children’s hospitals.METHODSWe conducted a multicenter retrospective cohort study of febrile infants aged ≤60 days hospitalized from 2016 to 2019 at 39 hospitals in the Pediatric Health Information System database. We excluded infants with complex chronic conditions, bacterial infections, lower respiratory tract viral infections, and those who required ICU admission. The primary outcomes were trends in LOS overall and for individual hospitals, adjusted for patient demographics and clinical characteristics. We also evaluated the hospital-level association between LOS and 30-day readmissions.RESULTSWe identified 11 868 eligible febrile infant encounters. The adjusted mean LOS for the study cohort decreased from 44.0 hours in 2016 to 41.9 hours in 2019 (P < .001). There was substantial variation in adjusted mean LOS across children’s hospitals, range 33.5–77.9 hours in 2016 and 30.4–100.0 hours in 2019. The change from 2016 to 2019 in adjusted mean LOS across individual hospitals also varied widely (−23.9 to +26.7 hours; median change −1.8 hours, interquartile range: −5.4 to 0.3). There was no association between hospital-level LOS and readmission rates (P = .70).CONCLUSIONSThe LOS for hospitalized febrile infants decreased marginally between 2016 and 2019, although overall LOS and change in LOS varied substantially across children’s hospitals. Continued quality improvement efforts are needed to reduce LOS for hospitalized febrile infants.

Cerebral Palsy (CP) describes a heterogenous group of non-progressive disorders of posture or movement, causing activity limitation, due to a lesion in the developing brain. CP is an umbrella term for a heterogenous condition and is, therefore, descriptive rather than a diagnosis. Each case requires detailed consideration of etiology. Our understanding of the underlying cause of CP has developed significantly, with areas such as inflammation, epigenetics and genetic susceptibility to subsequent insults providing new insights. Alongside this, there has been increasing recognition of the multi-organ dysfunction (MOD) associated with CP, in particular in children with higher levels of motor impairment. Therefore, CP should not be seen as an unchanging disorder caused by a solitary insult but rather, as a condition which evolves over time. Assessment of multi-organ function may help to prevent complications in later childhood or adulthood. It may also contribute to an improved understanding of the etiology and thus may have an implication in prevention, interventional methods and therapies. MOD in CP has not yet been quantified and a scoring system may prove useful in allowing advanced clinical planning and follow-up of children with CP. Additionally, several biomarkers hold promise in assisting with long-term monitoring. Clinicians should be aware of the multi-system complications that are associated with CP and which may present significant diagnostic challenges given that many children with CP communicate non-verbally. A step-wise, logical, multi-system approach is required to ensure that the best care is provided to these children. This review summarizes multi-organ dysfunction in children with CP whilst highlighting emerging research and gaps in our knowledge. We identify some potential organ-specific biomarkers which may prove useful in developing guidelines for follow-up and management of these children throughout their lifespan.

Neonatal encephalopathy (NE) is associated with abnormality of neurological function and involves multiorgan dysfunction. There are long-term complications such as cerebral palsy and developmental delay. Cardiac, renal, neurological and other organ dysfunctions are well described. Haematological dysfunction is relatively common and includes anaemia, thrombocytopenia, monocyte and neutrophil activation, hypofibrinogenemia and coagulopathy. There is a lack of consensus definitions of hematological parameters and optimal levels for intervention due to the lack of interventional studies in term neonates and the lack of knowledge of the optimal values during therapeutic hypothermia. However, derangements in hematological values are also associated with neurodevelopmental outcomes. This article outlines the different hematological complications associated with NE and therapeutic hypothermia and suggests a framework for management.

Neonatal Encephalopathy (NE) is a neurologic syndrome in term and near-term infants who have depressed consciousness, difficulty initiating and maintaining respiration, and often abnormal tone, reflexes and neonatal seizures in varying combinations. Moderate/severe NE affects 0.5-3/1000 live births in high-income countries, more in low- and middle-income countries, and carries high risk of mortality or disability, including cerebral palsy. Reduced blood flow and/or oxygenation around the time of birth, as with ruptured uterus, placental abruption or umbilical cord prolapse can cause NE. This subset of NE, with accompanying low Apgar scores and acidemia, is termed Hypoxic-Ischemic Encephalopathy. Other causes of NE that can present similarly, include infections, inflammation, toxins, metabolic disease, stroke, placental disease, and genetic disorders. Aberrant fetal growth and congenital anomalies are strongly associated with NE, suggesting a major role for maldevelopment. As new tools for differential diagnosis emerge, their application for prevention, individualized treatment and prognostication will require further systematic studies of etiology of NE.

BACKGROUND: Cerebral palsy (CP) is a heterogeneous group of non‐progressive disorders of posture or movement, caused by a lesion of the developing brain. Osteoporosis is common in children with cerebral palsy, particularly in children with reduced gross motor function, and leads to an increased risk of fractures. Gross motor function in children with CP can be categorised using a tool called the Gross Motor Function Classification System (GMFCS). Bisphosphonate increases bone mineral density (BMD) and reduces fracture rates. Bisphosphonate is used widely in the treatment of adult osteoporosis. However, the use of bisphosphonate in children with CP remains controversial, due to a paucity of evidence and a lack of recent trials examining the efficacy and safety of bisphosphonate use in this population. OBJECTIVES: To examine the efficacy and safety of bisphosphonate therapy in the treatment of low BMD or secondary osteoporosis (or both) in children with cerebral palsy (GMFCS Levels III to V) who are under 18 years of age. SEARCH METHODS: In September 2020, we searched CENTRAL, MEDLINE, Embase, six other databases, and two trial registers for relevant studies. We also searched the reference lists of relevant systematic reviews, trials, and case studies identified by the search, and contacted the authors of relevant studies in an attempt to identify unpublished literature. SELECTION CRITERIA: All relevant randomised controlled trials (RCTs), and quasi‐RCTs, comparing at least one bisphosphonate (given at any dose, orally or intravenously) with placebo or no drug, for the treatment of low BMD or osteoporosis in children up to 18 years old, with cerebral palsy (GMFCS Levels III to V). DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We were unable to conduct any meta‐analyses due to insufficient data, and therefore provide a narrative assessment of the results. MAIN RESULTS: We found two relevant RCTs (34 participants). Both studies included participants with non‐ambulatory CP or CP and osteoporosis. Participants in both studies were similar in severity of CP, age distribution, and sex distribution. The two trials used different bisphosphonate medications and different intervention durations, but further comparison of the interventions was not possible due to a lack of published data from one trial. One trial received funding and support from research, academic, and hospital foundations, with pharmaceutical companies providing components of the calcium and vitamin supplement; the other trial did not report sources of funding. We judged one study at an overall high risk of bias; the other as overall unclear risk of bias. Primary outcome. Compared to placebo or no treatment, both studies provided very low certainty evidence of improved BMD at least four months post‐intervention in children treated with bisphosphonate. Only one study (12 participants) provided sufficient detail to assess a measure of the effect, and reported an improvement at six months post‐intervention in lumbar spine z‐score (mean difference (MD) 18%, 95% confidence interval (CI) 6.57 to 29.43; very low certainty evidence). Secondary outcomes. Very low certainty evidence from one study found that bisphosphonate reduced serum N‐telopeptides (NTX) more than placebo; the other study reported that both bisphosphonate plus alfacalcidol and alfacalcidol alone reduced NTX, but did not compare groups. One study reported inconclusive results between groups for serum bone‐specific alkaline phosphatase (BAP). The other study reported that both bisphosphonate plus alfacalcidol and alfacalcidol alone reduced BAP, but did not compare groups. Neither study reported data for the effect of bisphosphonate treatment on changes in volumetric BMD in the distal radius or tibia, changes in fracture frequency, bone pain, or quality of life. One study reported that two participants had febrile events noted during their first dosing schedule, but no further adverse events were reported in either relevant study. AUTHORS' CONCLUSIONS: Based on the available evidence, there is very low certainty evidence that bisphosphonate treatment may improve bone health in children with cerebral palsy. We could only include one study with 14 participants in the assessment of the effect size; therefore, the precision of the effect estimate is low. We could only evaluate one planned primary outcome, as there was insufficient detail reported in the relevant studies. Further research from RCTs on the effect and safety of bisphosphonate to improve bone health in children with cerebral palsy is required. These studies should clarify the optimal standard treatment regarding weight‐bearing exercises, vitamin D and calcium supplementation, and should include fracture frequency as a primary outcome.

The implementation of the multidisciplinary Down Syndrome Health Surveillance clinic at Children’s Health Ireland at Tallaght, Dublin has shown significant improvements in the adherence to guidelines as well as providing health promotion strategies such as information on immunisations. Our project provides a framework which would be potentially emulated and used in other medical conditions. The reduction in clinic attendances and co-ordination of same-day appointments has improved parental satisfaction as well as the quality of care.

New cancer incidences worldwide will eclipse 18 million in 2019, with nearly 10 million cancer-related deaths. It is estimated that in the United States, almost 40% of individuals will be diagnosed with cancer in their lifetime. Surgical resection of primary tumors remains a cornerstone of cancer treatment; however, the surgical process can trigger an immune-suppressing sympathetic response, which promotes tumor growth of any residual cancerous cells post surgery. Regional and local anesthesia have become staples of anesthesia and analgesia during and after surgery. Recently, much evidence in the form of retrospective and prospective studies has come to light regarding the protective, antitumor properties of anesthetic and analgesic agents across a wide variety of cancers and patient demographics. It is believed that by blocking afferent pain signals, the body does not mount the sympathetic response that contributes to the perpetuation of disease after surgical treatment. This review, therefore, investigates these studies as they pertain to the treatment and outcomes of cancers treated surgically to elucidate the role of regional anesthesia in the propagation of cancer.

This article presents three cases of cranial nerve palsy following shoulder surgery with general anesthesia in the beach chair position. All patients underwent preoperative ultrasound-guided interscalene nerve block. Two cases of postoperative hypoglossal and one case of combined hypoglossal and recurrent laryngeal nerve palsies (Tapia’s syndrome) were identified. Through this case series, we provide a literature review identifying postoperative cranial nerve palsies in addition to the discussion of possible etiologies. We suggest that intraoperative patient positioning and/or airway instrumentation is most likely causative. We conclude that the beach chair position is a risk factor for postoperative hypoglossal nerve palsy and Tapia’s syndrome.

Histological chorioamnionitis (HCA) is associated with preterm birth and adverse neonatal outcomes. We evaluated the rise in C-reactive protein (CRP) in preterm infants as a predictor of HCA severity and outcomes.Consecutive preterm infants, born January 2009 to January 2014 in the National Maternity Hospital, Dublin, under 32 weeks' gestation or1.5 kg birthweight, were included. Histological chorioamnionitis was staged as maternal inflammatory response, foetal inflammatory response and non-HCA.Preterm infants (n = 518) were included with a mean gestational age 28.5 ± 2.8 weeks, birthweight 1.1 ± 0.3 kg, and 53.5% were male. Histological chorioamnionitis was found in 25.4%. Histological chorioamnionitis was present in 93.7% when CRP 5 mg/L, 65.2% when CRP 1-5 mg/L and in 19.4% when CRP 1 mg/L. When both the immature to total neutrophil (IT) ratio was0.2 and the CRP 1 mg/L the positive predictive value and negative predictive value for HCA were 92.5% and 84.9%, respectively. Histological chorioamnionitis was associated with more resuscitation and respiratory distress syndrome (both P .001). A CRP 10 mg/L was associated with a foetal inflammatory response and increased early-onset sepsis.Higher early CRP was a surrogate predictor of HCA and correlated with the severity of HCA. Higher CRP and HCA were associated with adverse early outcomes.

Patients diagnosed with triple negative breast cancer (TNBC) have an increased risk of rapid metastasis compared to other subtypes. Predicting long-term survival post-chemotherapy in patients with TNBC is difficult, yet enhanced infiltration of tumor infiltrating lymphocytes (TILs) has been associated with therapeutic response and reduced risk of metastatic relapse. Immune biomarkers that predict the immune state of a tumor and risk of metastatic relapse pre- or mid-neoadjuvant chemotherapy are urgently needed to allow earlier implementation of alternate therapies that may reduce TNBC patient mortality. Utilizing a neoadjuvant chemotherapy trial where TNBC patients had sequential biopsies taken, we demonstrate that measurement of T-cell subsets and effector function, specifically CD45RO expression, throughout chemotherapy predicts risk of metastatic relapse. Furthermore, we identified the tumor inherent interferon regulatory factor IRF9 as a marker of active intratumoral type I and II interferon (IFN) signaling and reduced risk of distant relapse. Functional implications of tumor intrinsic IFN signaling were demonstrated using an immunocompetent mouse model of TNBC, where enhanced type I IFN signaling increased anti-tumor immunity and metastasis-free survival post-chemotherapy. Using two independent adjuvant cohorts we were able to validate loss of IRF9 as a poor prognostic biomarker pre-chemotherapy. Thus, IRF9 expression may offer early insight into TNBC patient prognosis and tumor heat, allowing for identification of patients that are unlikely to respond to chemotherapy alone and could benefit from further immune-based therapeutic intervention.

Severe neurological impairment (SNI) is a term commonly used in the medical literature, though there is no agreed definition. This limits opportunities for research into healthcare needs, treatment opportunities, resource planning, and outcome. We reviewed the literature to establish consistency of use of the term and to place it in the context of other commonly employed terms used to describe children with severe, complex medical needs. Forty-two articles were included for full-text analysis, with 23 including a definition of SNI. Motor impairment, intellectual disability, communication difficulties, and increased care needs were included in the definition in 80%, 70%, 30%, and 13% of papers respectively. Dependence on others for decision-making, chronicity, and distinction between disorders of the central nervous system and peripheral nervous system were less frequently included. There is wide variation in the use of the term SNI. A consensus-based definition of this term would be useful to facilitate future research. WHAT THIS PAPER ADDS: There is inconsistency in use of the term severe neurological impairment (SNI), limiting research efforts. In defining SNI, considerations are mobility, intellectual disability, communication difficulties, and increased care needs. Distinction between acute and chronic, central and peripheral nervous system disorders, and dependence on others for decision-making were less significant.DEFICIENCIA NEUROLÓGICO SEVERO: UNA REVISIÓN DE LA DEFINICIÓN: El deficiencia neurológico severo es un término comúnmente utilizado en la literatura médica, aunque no existe una definición acordada. Esto limita las oportunidades de investigación sobre necesidades de atención médica, oportunidades de tratamiento, planificación de recursos y resultados. Revisamos la literatura para establecer la coherencia en el uso del término y colocarlo en el contexto de otros términos empleados comúnmente que se utilizan para describir a los niños con necesidades médicas graves y complejas. Se incluyeron 42 artículos para el análisis de texto completo, de los cuales 23 incluían una definición de deficiencia neurológico severo. La discapacidad motora, la discapacidad intelectual, las dificultades de comunicación y el aumento de las necesidades de atención se incluyeron en la definición en 80%, 70%, 30% y 13% de los artículos, respectivamente. La dependencia de otros para la toma de decisiones, la cronicidad y la distinción entre los trastornos del sistema nervioso central y el sistema nervioso periférico se incluyeron con menos frecuencia. Existe una amplia variación en el uso del término deficiencia neurológico severo. Una definición basada en el consenso de este término sería útil para facilitar futuras investigaciones.DEFICIÊNCIA NEUROLÓGICA SEVERA: UMA REVISÃO DA DEFINIÇÃO: A deficiência neurológica severa (DNS) é uma termo comumente usado na literatura médica, embora não tenha definição consensual. Isso limita as oportunidades de pesquisas sobre necessidades de saúde, oportunidades de tratamento, planejamento de recursos, e resultados. Nós revisamos a literature para estabelecer a consistência do uso do termo, e para colocá-lo no contexto de outros termos comumente empregados para descrever crianças com necessidades médicas severas e complexas. Quarenta e dois artigos foram incluídos para análise dos textos completes, com 23 includindo uma definição de DNS. Deficiência motora, deficiência intelectual, dificuldades de comunicação, e necessidades de cuidado aumentadas foram incluídas na definição 80%, 70%, 30%, e 13% dos artigos, respectivamente. Dependência de outros para tomada de decisões, cronicidade, e distinção entre desordens do sistema nervoso central e periférico foram menos frequentemente incluídas. Há grande variação no uso do termo DNS. Uma definição do termo baseada em consenso seria útil para facilitar futuras pesquisas.

We prospectively assessed inter-rater reliability of three physical function measures in Canadian intensive care unit (ICU) survivors in the inpatient setting. We enrolled patients who had an ICU length of stay of ≥ three days, were mechanically ventilated for ≥ 24 hr, and were ambulating independently before hospital admission. Weekly from ICU discharge to hospital discharge, two trained frontline clinicians, blinded to each other’s findings, independently performed the Physical Function ICU Test-scored (PFIT-s; score out of 10), 30-sec sit-to-stand (30STS; # of stands), and two-minute walk test (2MWT; distance in m), all within 24 hr. We calculated the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC90). We enrolled 42 patients. PFIT-s: in 36 patients with 66 paired scores, the ICC was 0.78 (95% confidence interval [CI], 0.66 to 0.86), the SEM was 1.04, and the MDC90 was 2.42. 30STS: in 35 patients with 67 paired scores, the ICC was 0.85 (95% CI, 0.76 to 0.90), the SEM was 1.91, and the MDC90 was 4.45. 2MWT: in 35 patients with 58 paired scores, the ICC was 0.78 (95% CI, 0.66 to 0.87), the SEM was 20.87, and the MDC90 was 48.69. These three measures show good inter-rater reliability when used by trained frontline clinicians to assess physical function in ICU survivors in the inpatient setting.

BackgroundBronchiolitis is the most common cause of respiratory hospitalisation in children aged MethodsWe searched for national and international CPGs relating to management of bronchiolitis in children and identified 16 recommendations which were formatted into 40 medical record audit indicator questions. A retrospective medical record review assessing compliance with the CPGs was conducted across three types of healthcare setting: hospital inpatient admissions, emergency department (ED) presentations and general practice (GP) consultations in three Australian states for children aged ResultsPurpose-trained surveyors conducted 13 979 eligible indicator assessments across 796 visits for bronchiolitis at 119 sites. Guideline adherence for management of bronchiolitis was 77.3% (95% CI 72.6 to 81.5) for children attending EDs, 81.6% (95% CI 78.0 to 84.9) for inpatients and 52.3% (95% CI 44.8 to 59.7) for children attending GP consultations. While adherence to some individual indicators was high, overall adherence to documentation of 10 indicators relating to history taking and examination was poorest and estimated at 2.7% (95% CI 1.5 to 4.4).ConclusionsThe study is the first to assess guideline-adherence in both hospital (ED and inpatient) and GP settings. Our study demonstrated that while the quality of care for bronchiolitis was generally adherent to CPG indicators, specific aspects of management were deficient, especially documentation of history taking.

Background: Although many performance-based measures assess patients’ physical function in intensive care unit (ICU) survivors, to our knowledge, there are no patient-reported ICU rehabilitation-specific measures assessing function. We developed the Patient-Reported Functional Scale-ICU (PRFS-ICU), which measures patients’ perceptions of their ability to perform 6 activities (rolling, sitting edge of bed, sit-to-stand and bed-to-chair transfers, ambulation, and stair climbing). Each item is scored from 0 (unable) to 10 (able to perform at pre-ICU level) to a maximum of 60. Objectives: Estimate the feasibility, reliability, responsiveness, and validity of the PRFS-ICU. Methods: This was a substudy of TryCYCLE, a single-center, prospective cohort examining the safety and feasibility of early in-bed cycling with mechanically ventilated patients (NCT01885442). To determine feasibility, we calculated the number of patients with at least 1 PRFS-ICU assessment during their hospital stay. To assess reliability, 2 raters blinded to each other’s assessments administered the PRFS-ICU within 24-hours of each other. We calculated the intraclass correlation coefficient (ICC; 95% confidence interval [CI]), standard error of measurement (SEM, 95% CI), and minimal detectable change (MDC90). To assess validity, we estimated convergent validity of the PRFS-ICU with the Functional Status Score for ICU (FSS-ICU), Medical Research Council Sum Score (MRC-SS), Physical Function Test for ICU (PFIT-s), Katz Index of Independence in Activities of Daily Living (Katz ADLs), and a pooled index using Pearson's correlation coefficient ( r, 95% CI). Results: Feasibility: 20 patients completed a PRFS-ICU assessment. Reliability and responsiveness: 16 patients contributed data. The ICC, SEM, and MDC90 were 0.91 (0.76, 0.97), 4.75 (3.51, 7.35), and 11.04 points, respectively. Validity: 19 patients contributed data and correlations were ( r [95% CI]): FSS-ICU (0.40 [−0.14, 0.76]), MRC-SS (0.51 [0.02, 0.80]), PFIT-s (0.43 [−0.13, 0.78]), Katz ADLs (0.53 [0.10, 0.79]), and pooled index (0.48 [−0.14, 0.82]). Conclusions: Our pilot work suggests the PRFS-ICU may be a useful tool to assess and monitor patients’ perceptions of function over time.

Two 3-oxo-Δ4 fetal bile acids, 3-oxachola-4,6-dien-24-oic acid (1) and 7α-hydroxy-3-oxochol-4-en-24-oic acid (2), occur normally in the human fetus but remain elevated in neonates and children with severe cholestatic liver disease due to an autosomal recessive inborn error of metabolism affecting Δ4-3-oxo-steroid 5β-reductase (AKR1D1). Relatively little is known about 1 and 2 in adult patients with liver disease. The chemical synthesis of 1 and 2 is therefore described and their quantitation in plasma by ultrarapid chromatography-triple quadrupole mass spectrometry. Plasma concentrations of 1 and 2 were investigated in 25 adult patients with varying degrees of liver cirrhosis with and without hepatocellular carcinoma (HCC). Highly statistically significant correlations (P 1 and 2 concentrations, both alone and combined. The presence of HCC did not influence these correlations. Plasma cholic, chenodeoxycholic, deoxycholic, lithocholic or ursodeoxycholic acids, free and as their glycine or taurine conjugates, did not correlate with Child–Pugh or MELD score when corrected for multiple comparisons. These findings demonstrate that plasma levels of fetal bile acids 3-oxachola-4,6-dien-24-oic acid and 7α-hydroxy-3-oxochol-4-en-24-oic acid and likely deteriorating AKR1D1 activity indicate the severity of liver cirrhosis measured by the Child–Pugh and MELD scores.

Iron is essential for growth and haematopoiesis but iron overload can have detrimental effects. The aim of this study is to correlate iron indices at 1 month of age in very low birth weight infants undergoing intensive care prior to additional iron supplementation and correlate results with clinical measures and 2 year corrected neurodevelopmental outcomes.A prospective observational cohort study was undertaken of very low birth weight infants at a tertiary neonatal intensive care unit. In 45 eligible infants, iron overload existed in 14 (31%) who had significantly decreased: mean (SD) gestational age at birth [26(2) v 28(2) weeks], birth weight [814(231)g v 1011(238)g], weight on assessment [1180(369)g v 1502(423)g], haemoglobin level at birth [13.8(3.1)g/dL v 16.1(2.5)g/dL] and mean corpuscular volume at assessment [85(4)fL v 90(6)fL] with increased number of red cell transfusions [4(2.5-5) v 1(0-2)] and volume of transfusions [65 (38)mL v 27 (23)mL]. Regression analysis determined the number of transfusions had the strongest correlation with iron status on testing. Neurodevelopmental outcomes at 2 years were not significantly different.Conclusion: Very low birth weight infants at risk of iron overload (≥2 red cell transfusions) may benefit from the measurement of iron indices prior to oral iron supplementation.

Introduction: Patients with multimorbidity are expected to adhere to complex medication regimens in order to manage their multiple chronic conditions. It has been reported the likelihood of adherence decreases as patients are prescribed more medications. Much medication adherence research to date is dominated by a single-disease focus, which is at odds with the rising prevalence of multimorbidity and may artificially underestimate the complexity of managing chronic illness. This review aims to describe the prevalence of medication non-adherence among patients with multimorbidity, and to identify potential predictors of non-adherence in this population. Methods: A systematic review will be conducted and reported according to PRISMA guidelines. PubMed, EMBASE, CINAHL and PsycINFO will be searched using a predefined search strategy from 2009–2019. Quantitative studies will be considered eligible for review if prevalence of medication non-adherence among adults with two or more chronic conditions is reported. Studies will be included in the review if available in English full text. Titles and abstracts will be screened by single review, with 20% of screening cross-checked by a second reviewer. Full-text articles will be screened by two independent reviewers, noting reasons for exclusions. Data extraction will be performed using a predefined extraction form. Quality and risk of bias assessment will be conducted using criteria for observational studies outlined by Sanderson et al. (2007). A narrative synthesis and, if feasible, meta-analysis will be conducted. Discussion: By exploring medication non-adherence from a multimorbidity perspective, the review aims to inform an evidence base for intervention development which accounts for the rising prevalence of patients with multiple chronic conditions. Study registration: The systematic review is prospectively registered in PROSPERO (CRD42019133849); registered on 12 June 2019.

Aim: To investigate the relationship between cytokines associated with innate immune cell activation and brain injury and outcome in infants with NE compared to neonatal controls.Methods: Serum and CSF biomarkers associated with activated neutrophils and monocytes [Interleukin-8 (IL-8) and Granulocyte-Macrophage-Colony-Stimulating-Factor (GM-CSF)] were serially measured using duplex immunoassays on days 1, 3 and 7 in term newborns with NE and controls. Results were compared to grade of encephalopathy, seizures, MRI brain imaging, mortality and Bayley Score of Infant and Toddler Development (Bayley-III) at 2 years of age.Results: Ninety-four infants had serum samples collected with 34 CSF samples. NE Grade II/III was significantly associated with elevated on day 2 serum IL-8. Mortality was best predicted by elevated day 1 IL-8. GM-CSF was initially elevated on day 1 and abnormal MRI imaging was associated with decreased day 2 GM-CSF. Elevated GM-CSF at day of life 6–7 correlated negatively with composite cognitive, language and motor Bayley-III scores at 2 years.Conclusion: Moderate or severe NE and mortality was associated with elevated IL-8. Day 2 GM-CSF could predict abnormal MRI results in NE and Bayley-III. Therefore, these cytokines are altered in NE and may predict early outcomes and further implicate inflammatory processes in NE.

A previously healthy 3-year-old boy presented with 6 days of fever and fatigue. Three days before, he saw his pediatrician and had negative rapid strep antigen and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction test results. Given persistent fever up to 40°C with decreased appetite and urine output, the patient presented to the emergency department. There was no reported rash, skin peeling, eye redness, redness of the oral mucosa, congestion, rhinorrhea, cough, shortness of breath, chest pain, abdominal pain, nausea, vomiting, or diarrhea. The patient had recently started preschool but had no known exposure to the coronavirus disease 2019 (COVID-19). On arrival, the patient was febrile to 39.2°C, mildly tachycardic, and normotensive. On examination, he had clear conjunctivae, a normal oropharynx, and moist mucous membranes. No rash, extremity swelling, or lymphadenopathy was appreciated. He was breathing comfortably, and his lungs were clear to auscultation bilaterally. His abdomen was soft and nontender with mild left-sided flank tenderness. Given the patient’s prolonged fever, multisystem inflammatory syndrome in children (MIS-C) was considered and an extensive laboratory evaluation was initiated, including all the laboratories suggested as potentially useful in the evaluation of MIS-C (Table 1). Laboratory results were notable for normal white blood cell and platelet counts and a metabolic panel with normal sodium and albumin. Inflammatory markers were elevated with a C-reactive protein (CRP) level of 14 mg/dL, an erythrocyte sedimentation rate (ESR) of 110 mm/hour, and mild elevations of ferritin, D-dimer, and fibrinogen levels. The patient’s troponin level was within normal limits, and his B-type natriuretic peptide (BNP) level was mildly elevated. A urinalysis was notable for small protein, negative nitrite results, small leukocyte esterase, …

Gastro-oesophageal reflux (GOR) is a common physiological state in infants and young children, with gastro-oesophageal reflux disease (GORD) its pathological manifestation. Management of GOR/GORD requires elimination of possible underlying causes, parental reassurance, modification of feeding and symptom mitigation, monitoring, and referral to paediatricians if warning signs are present. Published clinical practice guidelines (CPGs) seek to support clinicians and improve management. This study aimed to measure the proportion of Australian GOR/GORD paediatric care that was in line with CPG recommendations. National and international CPGs for GOR/GORD were systematically identified and candidate indicators extracted; a Delphi process selected 32 indicators relevant to Australian paediatric care in 2012 and 2013. Medical records were identified in General Practices, the offices of general paediatricians, Emergency Departments and inpatient settings. Adherence to indicators was assessed by nine trained paediatric nurses undertaking retrospective medical record review. Medical records were reviewed in 115 healthcare sites; identifying 285 children, three-quarters aged infants at the first presentation was higher if they were healthy and thriving (86.9% adherence: 95% CI 86.0–96.8), intermediate if they had feeding refusal (73.1%: 95% CI 56.0–86.3) and lower if they presented with irritability and unexplained crying (58.8%: 95% CI 28.2–85.0). A guideline targeting Australian health professionals caring for infants and children with GOR/GORD is warranted, highlighting the importance of differential diagnostic testing and avoidance of acid-suppression medication in infants.

Background: MRI scoring systems are used in the perinatal period to predict later neurodevelopmental outcome in infants with neonatal encephalopathy (NE). Our objective was to compare the predictive ability of 3 MRI scoring systems for neurodevelopmental outcome at 2 years of age in infants with NE. Methods: We retrospectively analysed MRI scans from term-born neonates with NE in the first two weeks of life between February 2011 and June 2015 using three scoring systems: Barkovich, NICHD-NRN and Weeke. Neurodevelopmental outcome was assessed using Bayley Scales of Infant and Toddler Development, third edition (Bayley-III) 2 years later. After adjusting for postmenstrual age at MRI scan and therapeutic hypothermia, the relationship between scoring systems and Bayley-III composite scores was assessed by regression analysis and logistic regression was used to calculate the predictive value of MRI scoring systems for adverse outcome (Bayley-III score of

Optimising public health physical distancing measures has been a critical part of the global response to the spread of COVID-19. Evidence collected during the current pandemic shows that the transmission rate of the virus is significantly reduced following implementation of intensive physical distancing measures. Adherence to these recommendations has been poorer than adherence to other key transmission reduction behaviours such as handwashing. There are a complex range of reasons that are likely to predict why people do not or only partially adhere to physical distancing recommendations. In the current project we aim to address the following research questions: (1) What are the psychosocial determinants of physical distancing for the general public and for key socio-demographic sub-groups (e.g., young adults, older adults, etc.)?; (2) Do current Government of Ireland COVID-19 physical distancing communications address the determinants of physical distancing?; and (3) How can communications be optimised and tailored to sub-groups to ensure maximum adherence to guidelines? These will be addressed by conducting three work packages (WPs). In WP1, we will work closely with the iCARE international study, which includes a large online survey of public responses to measures established to reduce and slow the spread of COVID-19, including physical distancing. We will analyse Irish data, comparing it to data from other countries, to identify the key psychosocial determinants of physical distancing behaviour. This will be followed by a qualitative study to explore in depth the barriers and facilitators of physical distancing behaviour among the Irish public (WP2). In WP3, we will conduct a content analysis and evidence mapping of current government messaging around physical distancing, to ensure the findings from this research feed into the development of ongoing communication and future messaging about physical distancing.

Asthma is the most common chronic condition of childhood. Self-management is integral to good asthma control. This qualitative paper explores how children with asthma and their parents perceive asthma, their experience with asthma, and how they manage symptoms, preventions and medications within and outside the home. We undertook 15 focus groups with 41 school-aged (6–11 years) children with asthma and 38 parents. Parents and their children attended the same focus groups. We used thematic analysis to analyse the transcripts. Our findings show the impact asthma can have on children’s social and emotional wellbeing and highlight how reliant school-aged children are on their parents to effectively manage their asthma. Parents reported being unsure when their child’s symptoms warranted visiting their doctor or hospital. Schools were identified as a source of difficulty regarding asthma management; families reported that children may be self-conscious about their asthma and using their inhaler at school. School policies and teachers’ lack of asthma knowledge were reported to exacerbate children’s reluctance to use their inhaler at school. Our results have implications for the design and implementation of children’s self-management interventions for their asthma, particularly when they are at school and away from their parents.

Background: Down’s syndrome (DS) is the most common chromosomal abnormality globally. Ireland has one of the highest rates of DS in the western world with an incidence of 1:444 live births. Congenital heart disease (CHD) and pulmonary hypertension (PH) are the commonest morbidities affecting the cardiovascular system in DS. PH is associated with significant morbidity and an increase risk of mortality. The impact of the diagnosis of DS, the presence of CHD and the associated PH on myocardial function during transition and over the first 2 years of age in this population is not well defined and warrants further study. In particular, serial measurements of pulmonary pressures in this population over the first week of age are lacking. This study aims to characterise myocardial function and pulmonary haemodynamics in infants with Down syndrome during the transitional period (over the first week of age) and throughout the first two years of age. Methods: A prospective, observational study utilising novel echocardiography techniques to assess myocardial function and pulmonary haemodynamics over the first two years of age in infants with Down Syndrome. A population of healthy infants without CHD or a diagnosis of DS will be recruited as controls. This study will be conducted across the three Dublin maternity units. Discussion: In total, 70 babies with DS have been enrolled into this study with 292 echocardiograms performed to date. Further evaluation of cardiac performance in DS infants with and without CHD may yield more insight into the pathophysiology of cardiac dysfunction and pulmonary hypertension that are recognised features in these patients. This could aid in our ability to monitor and treat patients, as well as improve our ability to predict outcomes.

Introduction Cerebral Palsy (CP) is a well-recognised neurodevelopmental disorder beginning in early childhood and persisting through life. CP registries from developed countries suggest its prevalence is 2–3 per 1000 live births. It has consistently proven a challenge to define CP, as documented by the numerous attempts. This review aimed to investigate both the consensus and controversy surrounding the definition of CP and to investigate which definition is currently the mostly widely accepted and applied. Methods A literature search was conducted using EMBASE, CINAHL and SCOPUS. The search was limited to articles available in English and peer-reviewed journals. Articles were screened in four stages by two independent reviewers and the Preferred Reporting Items for Systematic Reviews (PRISMA) was used. Results 375 articles were identified, and 41 full-text articles were included in the study. The literature outlined numerous definitions of CP. Most recently, a new consensus definition was proposed by Rosenbaum et al. which emerged from an international workshop on the definition and classification of CP, held in Maryland, July 2004. However, while widely accepted, this definition still faces criticism. Conclusions Overall, there has been a marked evolution from the first definition of CP by Little to the current consensus definition of Rosenbaum et al. Use of epidemiological data collected by CP registers and modern diagnostic techniques has paved the way for adjustments of previously scrutinised definitions. However, there is a need for a worldwide consensus to maintain a high accuracy rate of diagnosis and management.

To examine white matter abnormalities, measured by diffusion tensor imaging, in very preterm (32 weeks) and moderate-late preterm neonates (32-37 weeks) at term-equivalent age, compared with healthy full-term controls (≥37 weeks).A search of Medline (PubMed) was conducted to identify studies with diffusion data collected on very preterm, moderate-late preterm and full-term neonates, using the guidelines from the Meta-analysis of Observational Studies in Epidemiology and PRISMA statements.Eleven studies were included with diffusion tensor imaging data from 554 very preterm, 575 moderate-late preterm, and 318 full-term neonates. Widespread statistically significant diffusion measures were found in all preterm subgroups at term-equivalent age compared with full-term neonates, and this difference was more marked for the very preterm group. These abnormalities are suggestive of changes in the white matter microstructure in the preterm groups. The corpus callosum was a region of interest in both early and moderate-late preterm groups, which showed statistically significant diffusion measures in all 11 studies.Microstructural white matter changes may underpin the increased risk of neurodevelopmental disability seen in preterm infants in later life. diffusion tensor imaging may therefore be a useful prognostic tool for neuro-disability in preterm neonates.

Background The use of multiple medications (polypharmacy) is a concern in older people (≥65 years) and is associated with negative health outcomes. For older populations with multimorbidity, polypharmacy is the reality and the key challenge is ensuring appropriate polypharmacy (as opposed to inappropriate polypharmacy). This external pilot cluster randomised controlled trial (cRCT) aims to further test a theory-based intervention to improve appropriate polypharmacy in older people in primary care in two jurisdictions, Northern Ireland (NI) and the Republic of Ireland (ROI). Methods Twelve GP practices across NI (n=6) and the six counties in the ROI that border NI will be randomised to either the intervention or usual care group. Members of the research team have developed an intervention to improve appropriate polypharmacy in older people in primary care using the Theoretical Domains Framework of behaviour change. The intervention consists of two components: (1) an online video which demonstrates how a GP may prescribe appropriate polypharmacy during a consultation with an older patient and (2) a patient recall process, whereby patients are invited to scheduled medication review consultations with GPs. Ten older patients receiving polypharmacy (≥4 medications) will be recruited per GP practice (n=120). GP practices allocated to the intervention arm will be asked to watch the online video and schedule medication reviews with patients on two occasions; an initial and a 6-month follow-up appointment. GP practices allocated to the control arm will continue to provide usual care to patients. The study will assess the feasibility of recruitment, retention and study procedures including collecting data on medication appropriateness (from GP records), quality of life and health service use (i.e. hospitalisations). An embedded process evaluation will assess intervention fidelity (i.e. was the intervention delivered as intended), acceptability of the intervention and potential mechanisms of action. Discussion This pilot cRCT will provide evidence of the feasibility of a range of study parameters such as recruitment and retention, data collection procedures and the acceptability of the intervention. Pre-specified progression criteria will also be used to determine whether or not to proceed to a definitive cRCT. Trial registration ISRCTN, ISRCTN41009897. Registered 19 November 2019.

Background Post-term pregnancy is associated with an increased risk of maternal complications, respiratory distress and trauma to the neonate. Amniotic membrane sweeping has been recommended as a simple procedure to promote the spontaneous onset of labour. However, despite its widespread use, there is an absence of evidence on (a) its effectiveness and (b) its optimal timing and frequency. The primary aim of the MILO Study is to inform the optimal design of a future definitive randomised trial to evaluate the effectiveness (including optimal timing and frequency) of membrane sweeping to prevent post-term pregnancy. We will also assess the acceptability and feasibility of the proposed trial interventions to clinicians and women (through focus group interviews). Methods/design Multicentre, pragmatic, parallel-group, pilot randomised controlled trial with an embedded factorial design. Pregnant women with a live, singleton foetus ≥ 38 weeks gestation; cephalic presentation; longitudinal lie; intact membranes; English speaking and ≥ 18 years of age will be randomised in a 2:1 ratio to membrane sweep versus no membrane sweep. Women allocated randomly to a sweep will then be randomised further (factorial component) to early (from 39 weeks) versus late (from 40 weeks) sweep commencement and a single versus weekly sweep. The proposed feasibility study consists of four work packages, i.e. (1) a multicentre, pilot randomised trial; (2) a health economic analysis; (3) a qualitative study; and (4) a study within the host trial (a SWAT). Outcomes to be collected include recruitment and retention rates, compliance with protocol, randomisation and allocation processes, attrition rates and cost-effectiveness. Focus groups will be held with women and clinicians to explore the acceptability and feasibility of the proposed intervention, study procedures and perceived barriers and enablers to recruitment. Discussion The primary aim of the MILO Study is to inform the optimal design of a future definitive randomised trial to evaluate the effectiveness (including optimal timing and frequency) of membrane sweeping to prevent post-term pregnancy. Results will inform whether and how the design of the definitive trial as originally envisaged should be delivered or adapted. Trial registration ClinicalTrials.gov NCT04307199.

Background Severe Neurological Impairment (SNI) is a term for which there is no consistently used definition. This may hamper consistency in the reporting of research in the area and communication between professionals involved in the care of those with SNI. Objective We aimed to create an international, multidisciplinary, consensus-based definition of SNI. Design The Delphi method was employed to reach consensus on the definition of SNI. Method An international, multi-disciplinary expert panel was recruited. The process proceeded over three rounds with feedback provided to panellists between each of them. Consensus was defined as 70% agreement. A working definition was created and, following presentation at an international meeting and consultation with parent representatives, further refined, to create a finalised definition. Results Thirty-four expert panellists commenced the process. Six items reached the threshold of consensus. The finalised definition is as follows: “Severe Neurological Impairment describes a group of disorders of the central nervous system which arise in childhood, resulting in motor impairment, cognitive impairment and medical complexity, where much assistance is required with activities of daily living. The impairment is permanent but can be progressive or static.” Conclusion A consensus-based definition of SNI which includes multi-disciplinary, international and parental input has been created. This should prove useful for clinical, research and resource-planning purposes.

Neonatal Encephalopathy (NE) describes neonates with disturbed neurological function in the first post-natal days of life. NE is an overall term that does not specify the etiology of the encephalopathy although it often involves hypoxia-ischaemia. In NE, although neurological dysfunction is part of the injury and is most predictive of long-term outcome, these infants may also have multiorgan injury and compromise, which further contribute to neurological impairment and long-term morbidities. Therapeutic hypothermia (TH) is the standard of care for moderate to severe NE. Infants with NE may have co-existing immune, respiratory, endocrine, renal, hepatic, and cardiac dysfunction that require individualized management and can be impacted by TH. Non-neurological organ dysfunction not only has a negative effect on long term outcome but may also influence the efficacy of treatments in the acute phase. Post resuscitative care involves stabilization and decisions regarding TH and management of multi-organ dysfunction. This management includes detailed neurological assessment, cardio-respiratory stabilization, glycaemic and fluid control, sepsis evaluation and antibiotics, seizure identification, and monitoring and responding to biochemical and coagulation derangements. The emergence of new biomarkers of specific organ injury may have predictive value and improve the definition of organ injury and prognosis. Further evidence-based research is needed to optimize management of NE, prevent further organ dysfunction and reduce neurodevelopmental impairment.
