Exposure to bile and gastric juice can impact the aerodigestive microbiome in people with cystic fibrosis.

Studies of microbiota reveal inter-relationships between the microbiomes of the gut and lungs. This relationship may influence the progression of lung disease, particularly in patients with cystic fibrosis (CF), who often experience extraoesophageal reflux (EOR). Despite identifying this relationship, it is not well characterised.

Factors associated with clinical progression to severe COVID-19 in people with cystic fibrosis: A global observational study.

Background: This international study aimed to characterise the impact of acute SARS-CoV-2 infection in people with cystic fibrosis and investigate factors associated with severe outcomes. Methods Data from 22 countries prior to 13 December 2020 and the introduction of vaccines were included. It was de-identified and included patient demographics, clinical characteristics, treatments, outcomes and sequalae following SARS-CoV-2 infection.

Comparison of innovative communication approaches in nutrition to promote and improve health literacy.

The translation of scientific evidence into guidelines and advice is a fundamental aspect of scientific communication within nutrition and dietetics. For communication to be effective for all patients, health literacy (HL) must be considered, i.e.

The negative impact of chronic rhinosinusitis on the health-related quality of life among adult patients with cystic fibrosis.

Background: With improved survival in cystic fibrosis (CF) patients, it is crucial to evaluate the impact of chronic co-morbidities such as chronic rhinosinusitis (CRS). The objectives were 1) To determine the prevalence of CRS with a large series of CF patients 2) To evaluate the impact of CRS on the Health-Related Quality of Life (HRQoL) of CF patients and 3) To compare CRS-specific, CF-specific and general HRQoL instruments.

Methods: Consecutive CF patients from the Toronto Adult Cystic Fibrosis Centre were recruited between March 2018 and January 2020.

VOCAL: An observational study of ivacaftor for people with cystic fibrosis and selected non-G551D-CFTR gating mutations.

Background: VOCAL was an observational study of the effect of long-term ivacaftor on real-world clinical outcomes and healthcare resource utilization (HCRU) in people with cystic fibrosis (pwCF) in Italy, the Netherlands, and the UK.

Methods: pwCF aged ≥6 years with non-G551D-CFTR gating mutations were eligible. Prospective data were collected up to 48 months after enrollment; retrospective data were collected to ensure that 12 months of pre-ivacaftor data were available.

Isolation of is not associated with worse clinical outcomes during acute pulmonary exacerbations in cystic fibrosis.

The black yeast has been isolated in respiratory samples from people with cystic fibrosis (CF). However, adequate detection may require longer incubation periods than the current UK national standard for CF respiratory samples. Furthermore, it is unclear whether isolation of is associated with poorer clinical outcomes in CF.

British Thoracic Society survey of the career intentions of respiratory medicine specialty trainees in the UK.

There were respiratory consultant post vacancies in 82% of surveyed UK hospitals in 2021. Understanding respiratory trainees' career intentions is vital to plan and train a future respiratory workforce. In 2020, the British Thoracic Society surveyed trainee members (n=144) to assess career plans and perceived barriers and facilitators when applying for consultant posts.

Express Yourself: Quantitative Real-Time PCR Assays for Rapid Chromosomal Antimicrobial Resistance Detection in Pseudomonas aeruginosa.

The rise of antimicrobial-resistant (AMR) bacteria is a global health emergency. One critical facet of tackling this epidemic is more rapid AMR diagnosis in serious multidrug-resistant pathogens like Pseudomonas aeruginosa. Here, we designed and then validated two multiplex quantitative real-time PCR (qPCR) assays to simultaneously detect differential expression of the resistance-nodulation-division efflux pumps MexAB-OprM, MexCD-OprJ, MexEF-OprN, and MexXY-OprM, the AmpC β-lactamase, and the porin OprD, which are commonly associated with chromosomally encoded AMR.

The Presence of in the Respiratory Tract of Cystic Fibrosis Patients Accelerates Lung Function Decline: A Retrospective Review of Lung Function.

Exophiala dermatitidis is increasingly isolated from cystic fibrosis (CF) respiratory samples. The decision to treat is hampered by limited evidence demonstrating the clinical significance of isolating E. dermatitidis.

State-of-the-art review of lung imaging in cystic fibrosis with recommendations for pulmonologists and radiologists from the "iMAging managEment of cySTic fibROsis" (MAESTRO) consortium.

Objective: Imaging represents an important noninvasive means to assess cystic fibrosis (CF) lung disease, which remains the main cause of morbidity and mortality in CF patients. While the development of new imaging techniques has revolutionised clinical practice, advances have posed diagnostic and monitoring challenges. The authors aim to summarise these challenges and make evidence-based recommendations regarding imaging assessment for both clinicians and radiologists.

Managing Pulmonary Infection in Adults With Cystic Fibrosis: Adult Cystic Fibrosis Series.

Cystic fibrosis (CF) is characterized by chronic airway infection and progressive respiratory decline. Historically, a narrow spectrum of bacterial pathogens was believed to comprise the bulk of respiratory infections in CF, with Haemophilus influenzae and Staphylococcus aureus dominating childhood infections, and Pseudomonas aeruginosa or, less commonly, a member of the Burkholderia cepacia complex becoming the dominant infecting organism in adulthood. Today, the landscape is changing for airway infection in CF.

A Systematic Literature Review of Indoor Air Disinfection Techniques for Airborne Bacterial Respiratory Pathogens.

Interrupting the transmission of airborne (<≈5 µm) respiratory pathogens indoors is not a new challenge, but it has attracted unprecedented interest due to the COVID-19 pandemic during 2020-2021. However, bacterial respiratory pathogens with known or potential airborne transmission account for an appreciable proportion of the communicable disease burden globally. We aimed to systematically review quantitative, laboratory-based studies of air disinfection techniques for airborne respiratory bacteria.

A machine-learning assisted review of the use of habit formation in medication adherence interventions for long-term conditions.

Adherence to medication in long-term conditions is around 50%. The key components of successful interventions to improve medication adherence remain unclear, particularly when examined over prolonged follow-up periods. Behaviour change theories are increasingly interested in the utility of habit formation for the maintenance of health behaviour change, but there is no documentation on how habit has been conceptualised in the medication adherence intervention literature, or what effect the key technique identified in habit formation theory (context dependent repetition) has in these studies.

Standards of care guidance for sweat testing; phase two of the ECFS quality improvement programme.

More than five decades after the introduction of the quantitative pilocarpine iontophoresis technique, surveys still highlight inconsistencies in the performance and reporting of sweat tests in Europe. The sweat test remains key for the Cystic Fibrosis (CF) diagnostic pathway for all age groups, as it reflects the basic pathophysiological defect in the sweat gland. It is also critical following newborn screening as a confirmatory diagnostic step.

Review article: epidemiology, pathogenesis and management of liver disease in adults with cystic fibrosis.

Background: Cystic fibrosis-related liver disease (CFLD) is the leading cause of death in cystic fibrosis (CF), after pulmonary disease. To improve identification and management of this condition requires an understanding of the underlying disease mechanism.

Aims: This review summarises the current understanding of CFLD epidemiology, pathology, diagnosis and management.

Progress in precision medicine in cystic fibrosis: a focus on CFTR modulator therapy.

The genetic multisystem condition cystic fibrosis (CF) has seen a paradigm shift in therapeutic approaches within the past decade. Since the first clinical descriptions in the 1930s, treatment advances had focused on the downstream consequences of a dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) chloride ion channel. The discovery of the gene that codes for CFTR and an understanding of the way in which different genetic mutations lead to disruption of normal CFTR function have led to the creation and subsequent licensing of drugs that target this process.
