The utility of dynamic chest radiography in patients with asthma, COPD, COVID-19 and ILD: A pilot study.

Introduction And Objectives: Assessment of breathlessness requires a combination of imaging and lung function testing. Dynamic digital radiography (DDR) of the thorax is an imaging technique that allows physiological and anatomical information to be gathered at the time of chest X-ray and has the potential to significantly streamline diagnostic pathways. The aims of this study were to investigate the acceptability of DDR to patients and explore the correlation between DDR-derived measurements with lung volumes measured using full pulmonary function tests (PFT).

Dynamic chest radiography: a state-of-the-art review.

Dynamic chest radiography (DCR) is a real-time sequential high-resolution digital X-ray imaging system of the thorax in motion over the respiratory cycle, utilising pulsed image exposure and a larger field of view than fluoroscopy coupled with a low radiation dose, where post-acquisition image processing by computer algorithm automatically characterises the motion of thoracic structures. We conducted a systematic review of the literature and found 29 relevant publications describing its use in humans including the assessment of diaphragm and chest wall motion, measurement of pulmonary ventilation and perfusion, and the assessment of airway narrowing. Work is ongoing in several other areas including assessment of diaphragmatic paralysis.

Surveillance towards preventing paediatric incidence of respiratory syncytial virus attributable respiratory tract infection in primary and secondary/tertiary healthcare settings in Merseyside, Cheshire and Bristol, UK.

Introduction: Respiratory syncytial virus (RSV) is a common respiratory virus, particularly affecting children, and can cause respiratory infections such as croup and bronchiolitis. The latter is a leading cause of paediatric hospitalisation within the UK. Children <3 years of age and/or with underlying health conditions are more vulnerable to severe RSV infection.

Long-Term Real-World Outcomes of Mepolizumab and Benralizumab Among Biologic-Naive Patients With Severe Eosinophilic Asthma: Experience of 3 Years' Therapy.

Background: Biologic therapies such as mepolizumab and benralizumab offer treatment options for severe eosinophilic asthma (SEA), although long-term real-world data on their use are limited.

Objectives: To evaluate the impact of benralizumab and mepolizumab treatment among biologic-naive patients with SEA over 36 months and describe the incidence of super-response at 12 and 36 months, identifying potential predictive factors.

Methods: We conducted a retrospective, single-center study of patients with SEA who were given mepolizumab or benralizumab from May 2017 to December 2019, and who completed 36 months of therapy.

Comprehensive review of safety in Experimental Human Pneumococcal Challenge.

Introduction: Experimental Human Pneumococcal Challenge (EHPC) involves the controlled exposure of adults to a specific antibiotic-sensitive Streptococcus pneumoniae serotype, to induce nasopharyngeal colonisation for the purpose of vaccine research. The aims are to review comprehensively the safety profile of EHPC, explore the association between pneumococcal colonisation and frequency of safety review and describe the medical intervention required to undertake such studies.

Methods: A single-centre review of all EHPC studies performed 2011-2021.

Sensitivity of SARS-CoV-2 RNA polymerase chain reaction using a clinical and radiological reference standard.

Objectives: Diagnostic tests for SARS-CoV-2 are important for epidemiology, clinical management, and infection control. Limitations of oro-nasopharyngeal real-time PCR sensitivity have been described based on comparisons of single tests with repeated sampling. We assessed SARS-CoV-2 PCR clinical sensitivity using a clinical and radiological reference standard.
