Research regarding the epidemiology of paediatric trauma is limited. Using our unique classification, we describe paediatric trauma cases in a 10-year single-centre study to improve paediatric care.

Data regarding all paediatric trauma cases were extracted using a computerised medical record system that detected fracture diagnosis and epiphyseal injury. Registry search identified cases from January 2008 to December 2017. Age, sex, type of fracture, and details of injury mechanism were analysed, and we categorised the 'falls/turnover' mechanism using a new trauma energy classification based on speed and height.

A total of 1379 cases (953 boys and 426 girls) were included. The highest number of injuries (553 cases, 40%) was seen in school children (aged 6 to 10 years). Forearm fracture occurred most frequently, followed by humeral fracture. The most frequent injury mechanism in falls/turnover (969 cases, 70%) was sports in 272 cases (28%), playground equipment in 179 cases (18%), furniture in 102 cases (1y aid in understanding the injury mechanism independent of children's height. The fact that paediatric fractures occur at relatively low energy levels and are trended by age, activity, and sex, could be of potential universal use for their prevention and parent education.Prokaryotes use clustered regularly interspaced short palindromic repeat (CRISPR) and CRISPR-associated (Cas) proteins as an adaptive immune system. CRISPR-Cas systems preserve molecular memories of infections by integrating short fragments of foreign nucleic acids as spacers into the host CRISPR array in a process termed 'adaptation'. Functional spacers ensure a robust immune response by Cas effectors, which neutralizes subsequent infection through RNA-guided interference pathways. In this review, we summarize recent discoveries that have advanced our understanding of adaptation, with a focus on how functional spacers are generated and incorporated through many widespread, but type-specific, mechanisms. Finally, we highlight future directions and outstanding questions for a more thorough understanding of CRISPR adaptation.

As the landscape of haematological malignancies dramatically changes due to diagnostic and therapeutic advances, it is important to evaluate trends in clinical trial designs. The objective of our study was to describe the design of clinical trials for five common haematological malignancies with respect to randomisation and end-points. We also aimed to assess trends over time and examine the relationships of funding source and country of origin to proportions of randomisation and utilisation of clinical end-points.

This systematic review identified haematological malignancy clinical trials starting in 2015-2020 registered at ClinicalTrials.gov as of 20th February2021. Trial-related variables including randomisation status, type of primary end-point, and both projected and actual enrolment numbers were captured. Clinical end-points were defined as overall survival and quality of life, while surrogate end-points included all other end-points.

Of 2609 relevant trials included in this analysis, only one-fifr time. The vast majority of randomised haematological malignancy trials use surrogate primary end-points.

The immune microenvironment is an important modulator of tumour progression and treatment response. In invasive breast cancer, assessment of tumour-infiltrating lymphocytes (TILs) provides prognostic and predictive information. However, the clinical impact of TILs for ductal carcinoma in situ (DCIS) has not yet been demonstrated.

Post hoc analysis of the SweDCIS randomised radiotherapy trial including primary DCIS cases following breast-conserving surgery. TILs were assessed on haematoxylin-eosin sections (n=711) according to the International Immuno-Oncology Biomarker Working Group guidelines. TILs-scores were analysed as continuous and dichotomised (≤5% versus >5%) variable regarding ipsilateral breast events (IBEs) as the predefined primary endpoint.

Most women (61.9%) showed a TILs prevalence of ≤5%. High TILs-scores were associated with larger lesion size, human epidermal growth factor receptor 2 (HER2)-positivity, higher nuclear grade, and KI67-score. DCIS cases with high TILs prevalence had a to define patients with low-risk DCIS who can omit adjuvant therapy or patients with potential benefits from immunotherapy.Allergic bronchopulmonary aspergillosis (ABPA) is a complex allergic disorder caused by immune reactions against Aspergillus fumigatus. ABPA most commonly complicates the course of patients with poorly controlled asthma. Patients commonly present with uncontrolled asthma, fleeting pulmonary opacities, and bronchiectasis. Pathogenetically, ABPA is characterized by the persistence of A. fumigatus in the airways and an exaggerated type-2 immune response. The interest in ABPA stems from the fact that bronchiectasis in ABPA can be prevented if the disorder is diagnosed timely and treated appropriately. Herein, we summarize the current concepts in the epidemiology, pathogenesis, diagnosis, and treatment of ABPA.Patients with bronchiectasis are at high risk for nontuberculous mycobacteria (NTM) disease and suspicion should be high in the setting of worsening respiratory symptoms and disease progression on imaging. Meeting the case definition for NTM disease does not equal a decision to treat; risk and benefits of therapy should be discussed with patients. When treatment is initiated, a multidrug regimen should be used and selected based on susceptibility testing from a reliable laboratory. Monotherapy or macrolide-fluoroquinolone dual therapy should never be used. After discontinuation of therapy, ongoing mycobacterial sputum culture surveillance is needed, as infection relapse is common.Bronchiectasis is one of the diagnostic entities in the spectrum of pediatric chronic wet cough, causing significant morbidity and mortality. The pathobiology involves a vicious cycle of repeated infections, airway inflammation, dysregulated immunity, and tissue remodeling, resulting in impaired airway clearance, destruction of structural elements within the bronchial wall causing them to become dilated, and small-airway obstruction. Pediatric pathobiological studies are lacking, although there are recent data on the role of antibiotics in treating and preventing exacerbations. The focus has moved to understanding ways to prevent bronchiectasis and the role of novel drugs in preventing and treating bronchiectasis in children.Bronchiectasis is characterized by inflammation and abnormal dilatation of the airways secondary to various etiologies. A diagnosis of bronchiectasis requires that both radiological and clinical features are present. Determination of the etiology of bronchiectasis is important to allow specific treatment and should be guided by clinical features. The prognosis of bronchiectasis is highly variable, with severe cases suffering frequent exacerbations and hospitalizations, debilitating symptoms, and elevated mortality. Treatment is demanding, but adherence to treatment is associated with improved outcomes and should be assessed and reinforced. A partnership between patients and health care professionals is key to successful outcomes.The bronchiectasis and chronic obstructive pulmonary disease (COPD) overlap syndrome (BCOS) is increasingly recognized. BCOS is associated with poorer outcomes and increased mortality than in either disease alone. In the following article, the authors discuss why COPD and bronchiectasis might coexist, the radiological issues in diagnosing bronchiectasis in COPD, the understanding of prevalence and the factors that impact this, mortality and morbidity, microbiology associations, and the impact BCOS has on investigations and management.Bronchiectasis is a radiological diagnosis made using computed tomographic (CT) imaging. Although visual CT assessment is necessary for the diagnosis of bronchiectasis, visual assessment of disease severity and progression is challenging. Computer tools offer the potential to improve the characterization of lung damage in patients with bronchiectasis. Newer imaging techniques such as MRI with hyperpolarized gas inhalation have the potential to identify early forms of disease and are without the constraints of requiring ionizing radiation exposure.Bronchiectasis is a condition defined by permanently dilated airways and characterized by chronic cough and sputum and in many patients, recurrent exacerbations. Bronchiectasis is a heterogeneous condition, with numerous underlying risk factors and initiating conditions. These factors share in common the ability to impair the mechanisms by which the airways are protected from inflammatory or infectious insults. These underlying factors result in chronic bacterial infection of the airways, inciting a host inflammatory response in which the airways are the collateral damage. The damaged airways are unable to clear the infection, leading to ongoing inflammation and progressive damage.The microbiology in bronchiectasis has been historically defined by culture-based analysis of the airway microbiome and to date has largely focused on the detection and eradication of specific bacterial pathogens. Although central to our current understanding of disease, microbial culture alone masks the holistic complexity of the microbiome and does not account for potential microbial interactions that define specific clinical phenotypes such as frequent exacerbators. Advances in next-generation sequencing including their analytical technologies can further complement and build upon our current understanding of the microbiology and microbiome in bronchiectasis providing improved patient stratification with prognostic significance.Bronchiectasis treatment is challenging, and many recent randomized controlled trials have failed to prove any clinical improvement. The most reasonable explanation for that problem is the high heterogeneity of patients' groups. For that reason, there is an urgent need to find new biomarkers to better stratify patients. The present chapter addresses the future directions in biomarkers, omics technologies, endotypes, and new treatments toward a personalized medicine in the field of bronchiectasis.Antibiotics are an essential component of the management of patients with bronchiectasis. see more This article reviews the role of antibiotics in the treatment of exacerbations, for maintenance therapy to reduce exacerbation frequency, and for eradicating potentially harmful organisms such as Pseudomonas aeruginosa.In this article, we review airway clearance techniques, mucoactive agents, and the role of pulmonary rehabilitation in the treatment of patients with bronchiectasis. Topics include the physiology of airway clearance, specific techniques and therapies, and practical considerations for ensuring adherence to the therapies and education for the patient.Inflammatory bowel disease is associated with a wide spectrum of central, large, and small airway abnormalities, including bronchiectasis. The bronchiectasis associated with inflammatory bowel disease has a distinct phenotype, with marked inflammation and at times severe sterile bronchorrhea that can be responsive to inhaled corticosteroids.
