Registry-based randomised controlled trials: conduct, advantages and challenges-a systematic review.

Background: Registry-based randomised controlled trials (rRCTs) have been described as pragmatic studies utilising patient data embedded in large-scale registries to facilitate key clinical trial procedures including recruitment, randomisation and the collection of outcome data. Whilst the practice of utilising registries to support the conduct of randomised trials is increasing, the use of the registries within rRCTs is inconsistent. The purpose of this systematic review is to explore the conduct of rRCTs using a patient registry to facilitate trial recruitment and the collection of outcome data, and to discuss the advantages and challenges of rRCTs.

Airway and Systemic Immunoglobulin Profiling and Immune Response in Adult Asthma.

Introduction: Immunoglobulins play a vital role in host immune response and in the pathogenesis of conditions like asthma. Therapeutic agents such as monoclonal antibodies target specific elements of the asthmatic inflammatory cascade. Decisions to utilize these medications are often based on systemic inflammatory profiling without direct insight into the airway inflammatory profile.

Renal Denervation as a Complementary Treatment Option for Uncontrolled Arterial Hypertension: A Situation Assessment.

Uncontrolled arterial hypertension is a major global health issue. Catheter-based renal denervation has shown to lower blood pressure in sham-controlled trials and represents a device-based, complementary treatment option for hypertension. In this situation assessment, the authors, who are practicing experts in hypertension, nephrology, general practice and cardiology in the Republic of Ireland, discuss the current evidence base for the BP-lowering efficacy and safety of catheter-based renal denervation with different modalities.

ROCK STUDY in CF: sustained anti-inflammatory effects of lumacaftor-ivacaftor in sputum and peripheral blood samples of adult patients with cystic fibrosis-an observational study.

Background: Previous studies showed that the combination of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) corrector and potentiator, lumacaftor-ivacaftor (LUMA-IVA) provides meaningful clinical benefits in patients with cystic fibrosis who are homozygous for the Phe508del mutation. However, little is known about the effect of LUMA-IVA on Proinflammatory Cytokines (PICs).

Objectives: To investigate the impact of LUMA-IVA modulation on circulatory and airway cytokines before and after 12 months of LUMA-IVA treatment in a real-world setting.
