Infectious disease physicians in England have been diagnosing and managing occasional cases of viral hemorrhagic fever since 1971, including the United Kingdom's first case of Ebola virus disease in 1976. Specialist isolation facilities to provide safe and effective care have been present since that time. Following the emergence of Middle East respiratory syndrome (MERS) in 2012, and the avian influenza A (H7N9) outbreak in 2013, and the 2014-2016 Ebola virus disease outbreak in West Africa, clinical and public health preparedness and response pathways in England have been strengthened for these types of diseases, now called high-consequence infectious diseases (HCIDs).

In many species, social interactions decrease behavioral, hormonal, and neural responses to environmental stressors. While "social buffering" and its mechanisms have received considerable attention in mammals, we know less about the phenomenon in fish. The nonapeptide oxytocin regulates social behavior across vertebrates and plays an important role in social buffering in mammals.

Article Synopsis
  • The study evaluated the impact of the BioFire FilmArray Meningitis/Encephalitis Panel on managing childhood meningitis at two hospitals in the UK and Ireland, focusing on early diagnosis and treatment efficiency.
  • It involved a retrospective analysis of 460 children who underwent lumbar punctures, where the FilmArray identified 12 bacterial infections missed by standard culture methods, highlighting its diagnostic advantage.
  • Results showed that children with viral or negative cultures had shorter antibiotic courses and hospital stays with the FilmArray compared to previous practices, indicating improved treatment outcomes.

Article Synopsis
  • - The survey aimed to gather comprehensive demographic data on hereditary angioedema (HAE) and acquired C1 inhibitor deficiency in the UK to enhance service planning and patient care.
  • - A total of 1152 patients with HAE were identified, with a prevalence of 1:59,000 for HAE-1/2 and 1:734,000 for acquired C1 inhibitor deficiency, revealing significant patient demographics and treatment patterns.
  • - Findings showed that 45% of HAE patients were on long-term prophylaxis, primarily using danazol, and a significant number had acute treatment supplies available at home, highlighting the need for improved healthcare services for these conditions.

Aim: To synthesize qualitative evidence of premenopausal women's experiences of fertility decision-making with a diagnosis of breast cancer.

Background: Breast cancer is increasingly more common in premenopausal women who may have not yet considered starting a family or have completed their families.

Design: Qualitative evidence synthesis guided by Thomas and Harden's three-stage approach to thematic analysis.

Background: Both pathogenic bacteria and viruses are frequently detected in the nasopharynx (NP) of children in the absence of acute respiratory infection (ARI) symptoms. The aim of this study was to estimate the aetiological fractions for ARI hospitalisation in children for respiratory syncytial virus (RSV) and influenza virus and to determine whether detection of specific respiratory pathogens on NP samples was associated with ARI hospitalisation.

Methods: 349 children up to 5 years of age hospitalised for ARI (following a symptom-based case definition) and 306 hospital controls were prospectively enrolled in 16 centres across seven European Union countries between 2016 and 2019.

Context-based sensorimotor routing is a hallmark of executive control. Pharmacological inactivations in rats have implicated the midbrain superior colliculus (SC) in this process. But what specific role is this, and what circuit mechanisms support it? Here we report a subset of rat SC neurons that instantiate a specific link between the representations of context and motor choice.

A six-week-old infant presented in extremis and was diagnosed with dextro-transposition of the great arteries, intact ventricular septum, features of left ventricular deconditioning, and abnormal coronary arteries. Treatment with prostaglandin E1 and balloon atrial septostomy was insufficient, necessitating extracorporeal membrane oxygenation (ECMO). Severe acute respiratory syndrome coronavirus-2 was detected.

Purpose: To conduct a systematic review and meta-analysis of lung cancer among acrylonitrile-exposed workers.

Methods: A literature search through April 2020 was performed to identify relevant cohort and case-control studies. Data from these studies were meta-analyzed to generate summary relative risk estimates (SRREs).

Between February and May 2020, during the first wave of the COVID-19 pandemic, paediatric emergency departments in 12 European countries were prospectively surveyed on their implementation of SARS-CoV-2 disease (COVID-19) testing and infection control strategies. All participating departments (23) implemented standardised case definitions, testing guidelines, early triage and infection control strategies early in the outbreak. Patient testing criteria initially focused on suspect cases and later began to include screening, mainly for hospital admissions.

Background: The prevalence of extended-spectrum beta-lactamase producing Εnterobacteriaceae (ESBL-PE) is increasing globally. ESBL-PE are an important cause of urinary tract infections (UTIs) in children. We aimed to characterize the clinical presentation, treatment and outcomes of childhood UTI caused by ESBL-PE in Europe.

Background: Quinolone antibiotics have a broad spectrum of activity including against Gram-negative organisms (especially ), but their use has been associated with the development of seizures. Our objective was to evaluate the association between the administration of quinolones and seizures for three groups of children: those with epilepsy; those with other CNS disorders; and those without any CNS disorder.

Method: We conducted a systematic review of the MEDLINE, EMBASE and CENTRAL databases.

Introduction: The UNAIDS 90-90-90 targets for the cascade of care are widely used to monitor the success of HIV care programmes but there are few studies in children. We assessed the cascade for children and adolescents living with HIV in the national Collaborative HIV Paediatric Study (CHIPS) in the UK and Ireland.

Methods: Utilizing longitudinal data from CHIPS we compared the cascade of care for 2010, 2013 and 2016.

Type D personality has been consistently associated with adverse cardiovascular health with atypical cardiovascular reactions to psychological stress one plausible underlying mechanism. However, whether this varies by sex and social context has received little attention. This study examined the interaction between Type D personality, sex and social context on cardiovascular reactivity to acute stress.

Purpose: To conduct a systematic literature review and meta-analysis of studies of lympho-hematopoietic cancers (LHC) and breast cancer risk among persons occupationally exposed to ethylene oxide (EO).

Methods: We performed a literature search for articles available in PubMed and Web of Science databases to identify literature and subsequently systematically searched the reference lists of identified studies, published review papers and meta-analyses, as well as relevant government or regulatory documents. We qualitatively reviewed 30 studies and conducted meta-analyses on 13 studies.
