Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.

Background: With many rare tumour types, acquiring the correct diagnosis is a challenging but crucial process in paediatric oncology. Historically, this is done based on histology and morphology of the disease. However, advances in genome wide profiling techniques such as RNA sequencing now allow the development of molecular classification tools.

Introduction And Objective: Imiquimod (IQ) is an immunomodulator used in the management of penile intraepithelial neoplasia (PeIN) lesions. However, IQ treatment may be associated with bothersome side effects (SEs). To date, studies reporting on this morbidity and evaluating predictors of response to IQ are scarce and included small cohorts.

ERS/ATS Global Lung Function Initiative normal values and classifying severity based on z-scores instead of per cent predicted.

Breathe (Sheff)

October 2024

Pulmonary Function Testing, Department of Pulmonary Medicine, Medisch Spectrum Twente, Enschede, The Netherlands.

Among the most discussed issues in the field of pulmonary function testing are reference equations and standardised methods of interpreting pulmonary function test (PFT) results. The Global Lung Function Initiative (GLI) task force gathered information from multiple countries with diverse ethnicities to create a multi-ethnic reference formula suitable for a broad age range. Their first output was the GLI-2012 spirometry reference equations.

Background: Behavioral parent training (BPT) is a well-established intervention for children with attention-deficit/hyperactivity disorder (ADHD), but most programs are long, which may limit their accessibility. This could be improved by making programs shorter. Here, we studied (1) the feasibility of a new brief BPT program and its procedures, and (2) pre-post changes in daily rated problem behaviors (primary outcome), children's disruptive behaviors, ADHD/ODD characteristics, impairment, and parents' sense of parenting competence (secondary outcomes).

Objective: Loss of sense of smell is a cardinal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP) and significantly impacts health-related quality-of-life. Dupilumab significantly improved smell outcomes (loss of smell [LoS] score; University of Pennsylvania Smell Identification Test [UPSIT]) versus placebo in the phase 3 SINUS-24/-52 studies (clinicaltrials.gov, NCT02898454/NCT02912468) in patients with severe CRSwNP.

Article Synopsis
  • The study focuses on developing guidelines for the safe use of fluoroscopy in gastrointestinal endoscopy, balancing its benefits with concerns about radiation exposure to patients and healthcare workers.
  • A modified Delphi method was used, involving three rounds of surveys with 46 experts, resulting in 43 proposed statements, of which 31 achieved consensus and were prioritized across various categories such as Patient Safety and Staff Safety.
  • The final consensus statements highlight the importance of education and safety measures, with a significant majority rated as high priority, aiming to enhance safety culture in healthcare settings while utilizing fluoroscopy.

Prenatal detection of cardiac abnormalities has increased significantly over the past few decades, such that fetal cardiology has developed into a sub-specialty of paediatric and congenital cardiology. As this speciality develops further and extends across Europe and more globally, it is important to standardize the requirements for training and subsequent practice, to optimize prenatal diagnosis and perinatal care. In addition to the knowledge and technical skills required to make a correct diagnosis, the counseling of families after diagnosis and the planning of appropriate perinatal management is equally important.

Fundus images allow for non-invasive assessment of the retinal vasculature whose features provide important information on health. Using a fully automated image processing pipeline, we extract 17 different morphological vascular phenotypes, including median vessels diameter, diameter variability, main temporal angles, vascular density, central retinal equivalents, the number of bifurcations, and tortuosity, from over 130,000 fundus images of close to 72,000 UK Biobank subjects. We perform genome-wide association studies of these phenotypes.

Controlled human infection models (CHIMs) are a critical tool for the understanding of infectious disease progression, characterising immune responses to infection and rapid assessment of vaccines or drug treatments. There is increasing interest in using CHIMs for vaccine development and an obvious need for widely available and fit-for-purpose challenge agents. Inno4Vac is a large European consortium working towards accelerating and de-risking the development of new vaccines, including the development of CHIMs for influenza, respiratory syncytial virus and Clostridioides difficile.

PLoS One

November 2024

Institut de Recherche en Sciences de la Santé-Clinical Research Unit of Nanoro (IRSS-CRUN), Nanoro, Burkina Faso.

Background: The hormonal shift occurring in pregnant women is crucial for the outcome of pregnancy. We conducted a study in pregnant women living in a malaria endemic area to determine the potential effect of gestational age on the modulation of the endocrine system by cortisol and prolactin production during pregnancy.

Methods: Primigravidae and multigravidae with a gestational age between 16-20 weeks were included in the study and followed up to delivery and 6-7 weeks thereafter.

Background: Historically, patients with metastatic renal cell carcinoma (mRCC) have been offered upfront cytoreductive nephrectomy (CN) followed by systemic therapy. Currently, CN is no longer the standard of care (SOC) based on the randomised phase 3 CARMENA study performed in the vascular endothelial growth factor receptor tyrosine kinase inhibitor era. With the advent of immune checkpoint inhibitor (ICI) combination therapy in first line, the role of CN needs to be reassessed.

J Allergy Clin Immunol

October 2024

Department of Otorhinolaryngology, Upper Airways Research Laboratory, Ghent University, Ghent, Belgium; Clinic for ENT diseases and Head and Neck Surgery, University Clinic Münster, Münster, Germany.

Article Synopsis
  • Pivotal studies have shown that dupilumab significantly improves nasal polyp scores, symptom scores, and overall quality of life in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
  • A large-scale evaluation at six European centers found that after 24 and 52 weeks of treatment, patient outcomes consistently improved, regardless of demographic factors or prior treatments.
  • By the end of the study, a substantial percentage of the patients met improved health criteria, indicating that dupilumab remains effective over time and not influenced by previous sinus surgeries or other major health issues.
