Background: Food insecurity (FI) is more prevalent in people with cystic fibrosis (PwCF) than the reported national prevalence, but there are limited data on the relationship between FI and health outcomes in PwCF. The objective of this study was to analyze the relationship between FI in PwCF and pulmonary and nutritional status.
Methods: We leveraged an electronic cross-sectional survey that ascertained FI status and gave participants the option to link their survey data to their records in the Cystic Fibrosis Foundation Patient Registry (CFFPR). Linear regression and negative binomial models were used to estimate the associations in mean differences between FI and percent predicted FEV1 (ppFEV1), nutritional indices, and hospitalizations.
Results: There were 1,856 respondents, 1,234 (66.5 %) of whom granted permission to link to the CFFPR. FI was present in 352 (28 %) of the respondents. FI was associated with lower ppFEV1 (-6.5; 95 % CI -9.9, -3.1); however, this was no longer statistically significant after adjusting for confounders. FI was independently associated with increased hospitalizations. Higher weight for age was significantly associated with FI in the adjusted model, but there were no significant associations between height for age or absolute weight and body mass index (BMI) in adults.
Conclusions: FI in PwCF is associated with adverse health outcomes. These results support screening for FI during routine visits. Further studies are needed to investigate causal relationships between FI and adverse clinical outcomes.

Effect of CFTR modulators Elexacaftor/Tezacaftor/Ivacaftor on lipid metabolism in human bronchial epithelial cells.

Cystic Fibrosis (CF) is a life-threatening hereditary disease resulting from mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene that encodes a chloride channel essential for ion transport in epithelial cells. Mutations in CFTR, notably the prevalent F508del mutation, impair chloride transport, severely affecting the respiratory system and leading to recurrent infections. Recent therapeutic advancements include CFTR modulators such as ETI, a combination of two correctors (Elexacaftor and Tezacaftor) and a potentiator (Ivacaftor), that can improve CFTR function in patients with the F508del mutation.

Background: Children with cystic fibrosis are more likely to become severely unwell with influenza-associated illness compared to children without chronic lung disease. The provision of accessible influenza vaccinations is essential in the prevention of infection.
Objectives: To describe the prevalence of the influenza vaccine uptake in children with cystic fibrosis from 2016 to 2020 at a single tertiary paediatric hospital site and determine if the COVID pandemic of 2020 and the introduction of telehealth encounters affected the vaccine uptake.

Cystic Fibrosis (CF) is a life-shortening autosomal recessive disease caused by mutations in the CFTR gene, resulting in functional impairment of the encoded ion channel. F508del mutation, a trinucleotide deletion, is the most frequent cause of CF affecting approximately 80% of persons with cystic fibrosis (pwCFs). Even though current pharmacological treatments alleviate the F508del-CF disease symptoms there is no definitive cure.

Background: Recent findings have highlighted that abnormal energy metabolism is a key feature of autosomal-dominant polycystic kidney disease (ADPKD). Emerging evidence suggests that nutritional ketosis could offer therapeutic benefits, including potentially slowing or even reversing disease progression. This systematic review aims to synthesise the literature on ketogenic interventions to evaluate the impact in ADPKD.

Granulomatous mastitis (GM) is a rare, benign, but chronic and recurrent inflammatory breast disease that significantly impacts physical and psychological well-being. It often presents symptoms such as pain, swelling, and discharge, leading to diagnostic confusion with malignancy. The etiology of GM remains unclear, though autoimmune and multifactorial components are suspected.
