Exploring the lived experiences of diagnostic radiographers after transitioning to non-emergency imaging settings.

Introduction: The demand for diagnostic imaging in emergency clinical settings has increased in recent years, placing pressure on the available workforce. However, challenges including staff shortages and inflexible shift patterns may prompt radiographers to leave emergency settings. This study explores the lived experiences of radiographers who have transitioned to non-emergency settings and factors that might influence their decision to return.

Health services for aboriginal and Torres Strait Islander children in remote Australia: A scoping review.

In Australia, there is a significant gap between health outcomes in Indigenous and non-Indigenous children, which may relate to inequity in health service provision, particularly in remote areas. The aim was to conduct a scoping review to identify publications in the academic and grey literature and describe 1) Existing health services for Indigenous children in remote Australia and service use, 2) Workforce challenges in remote settings, 3) Characteristics of an effective health service, and 4) Models of care and solutions. Electronic databases of medical/health literature were searched (Jan 1990 to May 2021).

Which outcomes should be used in future bronchiolitis trials? Developing a bronchiolitis core outcome set using a systematic review, Delphi survey and a consensus workshop.

Objectives: The objective of this study was to develop a core outcome set (COS) for use in future clinical trials in bronchiolitis. We wanted to find out which outcomes are important to healthcare professionals (HCPs) and to parents and which outcomes should be prioritised for use in future clinical trials.

Design And Setting: The study used a systematic review, workshops and interviews, a Delphi survey and a final consensus workshop.

Establishing and augmenting views on the acceptability of a paediatric critical care randomised controlled trial (the FEVER trial): a mixed methods study.

Objective: To explore parent and staff views on the acceptability of a randomised controlled trial investigating temperature thresholds for antipyretic intervention in critically ill children with fever and infection (the FEVER trial) during a multi-phase pilot study.

Design: Mixed methods study with data collected at three time points: (1) before, (2) during and (3) after a pilot trial.

Setting: English, Paediatric Intensive Care Units (PICUs).

National survey of feasibility of NIV trials for management of children with bronchiolitis.

Background: Bronchiolitis is a major cause of admission to hospital in children. Non-invasive ventilation (NIV) support with continuous positive airway pressure (CPAP) or high-flow nasal cannula (HFNC) oxygen is routinely used for infants in the UK with bronchiolitis.

Objective: To establish UK paediatric practice regarding management of bronchiolitis, and to explore issues pertinent to the design of a potential future randomised controlled trial of NIV.

Endoplasmic reticulum stress in the dorsal root ganglia regulates large-conductance potassium channels and contributes to pain in a model of multiple sclerosis.

Neuropathic pain is a common symptom of multiple sclerosis (MS) and current treatment options are ineffective. In this study, we investigated whether endoplasmic reticulum (ER) stress in dorsal root ganglia (DRG) contributes to pain hypersensitivity in the experimental autoimmune encephalomyelitis (EAE) mouse model of MS. Inflammatory cells and increased levels of ER stress markers are evident in post-mortem DRGs from MS patients.

Microglia response following acute demyelination is heterogeneous and limits infiltrating macrophage dispersion.

Microglia and infiltrating macrophages are thought to orchestrate the central nervous system (CNS) response to injury; however, the similarities between these cells make it challenging to distinguish their relative contributions. We genetically labeled microglia and CNS-associated macrophages to distinguish them from infiltrating macrophages. Using single-cell RNA sequencing, we describe multiple microglia activation states, one of which was enriched for interferon associated signaling.

Review of Aboriginal child health services in remote Western Australia identifies challenges and informs solutions.

Background: Despite a national focus on closing the gap between Aboriginal and non-Aboriginal child health outcomes in Australia, there remain significant challenges, including provision of health services in very remote communities. We aimed to identify and map child health services in the very remote Fitzroy Valley, West Kimberley, and document barriers to effective service delivery.

Methods: Identification and review of all regional child health services and staffing in 2013.

Parents' prioritised outcomes for trials investigating treatments for paediatric severe infection: a qualitative synthesis.

Objective: To identify parents' prioritised outcomes by combining qualitative findings from two trial feasibility studies of interventions for paediatric suspected severe infection.

Design: Qualitative synthesis combining parent interview data from the Fluids in Shock (FiSh) and Fever feasibility studies. Parents had experience of their child being admitted to a UK emergency department or intensive care unit with a suspected infection.

Permissive versus restrictive temperature thresholds in critically ill children with fever and infection: a multicentre randomized clinical pilot trial.

Background: Fever improves pathogen control at a significant metabolic cost. No randomized clinical trials (RCT) have compared fever treatment thresholds in critically ill children. We performed a pilot RCT to determine whether a definitive trial of a permissive approach to fever in comparison to current restrictive practice is feasible in critically ill children with suspected infection.

Different temperature thresholds for antipyretic intervention in critically ill children with fever due to infection: the FEVER feasibility RCT.

Background: Fever accelerates host immune system control of pathogens but at a high metabolic cost. The optimal approach to fever management and the optimal temperature thresholds used for treatment in critically ill children are unknown.

Objectives: To determine the feasibility of conducting a definitive randomised controlled trial (RCT) to evaluate the clinical effectiveness and cost-effectiveness of different temperature thresholds for antipyretic management.

Voluntary wheel running reveals sex-specific nociceptive factors in murine experimental autoimmune encephalomyelitis.

Multiple sclerosis (MS) is an inflammatory, neurodegenerative autoimmune disease associated with sensory and motor dysfunction. Although estimates vary, ∼50% of patients with MS experience pain during their disease. The mechanisms underlying the development of pain are not fully understood, and no effective treatment for MS-related pain is available.

Non-invasive ventilation for the management of children with bronchiolitis (NOVEMBR): a feasibility study and core outcome set development protocol.

Background: Bronchiolitis is an acute lower respiratory infection which predominantly affects young children. Treatment for bronchiolitis is limited to supportive therapy. Nasal oxygen therapy is part of routine care, and delivery now incorporates varying levels of non-invasive continuous positive airway pressure and/or high-flow nasal cannula oxygen therapy.

Potential impact of maternal vaccination on life-threatening respiratory syncytial virus infection during infancy.

Background: Respiratory syncytial virus (RSV) infection is an important cause of infant mortality. Here, we estimated the potential impact of maternal vaccination against RSV on life-threatening RSV infection in infants.

Methods: We developed a mathematical model for maternal vaccine-induced antibody dynamics and used characteristics of a maternal RSV vaccine currently in phase 3 of clinical development.

Transaminase levels reflect disease severity in children ventilated for respiratory syncytial virus (RSV) bronchiolitis.

Bronchiolitis, often caused by respiratory syncytial virus (RSV), is the commonest cause of hospitalisation in infancy. Serum transaminases are sometimes raised in children with bronchiolitis. We tested the hypothesis that raised transaminases are associated with increased disease severity in children ventilated for bronchiolitis.

Global respiratory syncytial virus-associated mortality in young children (RSV GOLD): a retrospective case series.

Background: Respiratory syncytial virus (RSV) infection is an important cause of pneumonia mortality in young children. However, clinical data for fatal RSV infection are scarce. We aimed to identify clinical and socioeconomic characteristics of children aged younger than 5 years with RSV-related mortality using individual patient data.

Manipulation of Neurotransmitter Levels Has Differential Effects on Formalin-Evoked Nociceptive Behavior in Male and Female Mice.

Unlabelled: Changes in serotonin (5-hydroxytryptamine; 5-HT), noradrenaline (NA), and γ-aminobutyric acid (GABA) levels in the spinal cord are known to occur in response to nociceptive stimuli, yet little research has examined possible underlying sex differences in these changes and how they might affect nociception. We have used pharmacological approaches in a well established model of tonic nociception, the formalin test, to explore the effects of altering neurotransmitter levels on nociceptive responses in male and female C57BL/6 mice. The monoamine oxidase (MAO) inhibitor phenelzine (PLZ), its metabolite phenylethylidenehydrazine (PEH), and a derivative compound of PLZ, N(2)-acetylphenelzine (N(2)-AcPLZ), were used to increase endogenous levels of: GABA, 5-HT, and NA (PLZ); GABA alone (PEH); or 5-HT and NA only (N(2)-AcPLZ).

Facial hypersensitivity and trigeminal pathology in mice with experimental autoimmune encephalomyelitis.

Trigeminal neuropathic pain is a well-recognized complication of the demyelinating disease multiple sclerosis (MS). However, the mechanisms underlying MS-related trigeminal neuropathic pain are poorly understood. This can be attributed, at least in part, to the lack of an animal model that exhibits trigeminal pathology similar to that described in MS.

An observational study examining the relationship between respiratory symptoms, airway inflammation and bacteriology in children with severe neurodisability.

Background: Children with severe neurodisability (ND) commonly suffer from chronic respiratory symptoms that impact greatly on quality of life, and lead to recurrent hospital admissions. This morbidity (and its causes) is poorly described, despite being well recognised by paediatricians. In this study, we characterised respiratory symptoms in children with ND at times of stability and deterioration.

Characterisation of acute respiratory infections at a United Kingdom paediatric teaching hospital: observational study assessing the impact of influenza A (2009 pdmH1N1) on predominant viral pathogens.

Background: According to the World Health Organisation, influenza A (2009 pdmH1N1) has moved into the post-pandemic phase, but there were still high numbers of infections occurring in the United Kingdom in 2010-11. It is therefore important to examine the burden of acute respiratory infections at a large children's hospital to determine pathogen prevalence, occurrence of co-infection, prevalence of co-morbidities and diagnostic yield of sampling methods.

Methods: This was a retrospective study of respiratory virus aetiology in acute admissions to a paediatric teaching hospital in the North West of England between 1st April 2010 and 31st March 2011.
