Article Abstract

There is a well-established association between cystic fibrosis (CF) and malnutrition. Several comorbid conditions have also been associated with undernutrition in people with cystic fibrosis (PwCF). Highly effective modulator therapy has allowed for a paradigm shift altering disease progression and management. Modulator use has even been associated with acceleration of weight trajectory causing overnutrition, which can lead to cardiovascular and metabolic comorbid conditions. This review explores how nutritional status is evolving in the era of cystic fibrosis transmembrane conductance regulator (CFTR) modulators in people with CF, specifically in children. By synthesizing current research, we aim to support pediatric healthcare providers and nutritionists in delivering tailored, proactive nutritional care in this new therapeutic landscape.

Background Although advances in care have improved cystic fibrosis (CF) outcomes in higher-income countries (HICs), the situation remains alarming in lower-income countries (LICs). Methods People with CF (pwCF) enrolled in the European Cystic Fibrosis Society Patient Registry (ECFSPR) and carrying at least one F508del variant allele were evaluated in 2017 and in 2022 for predicted percent forced expiratory volume (ppFEV1), underweight status, and chronic Pseudomonas aeruginosa (Pa) infection, according to the gross national income (GNI) per capita divided into three terciles (low-income countries, LICs; middle-income countries, MICs; and high-income countries, HICs). Survival was evaluated in the periods 2013-2017 and 2018-2022.

Chronic diarrhea is a frequent gastrointestinal complication in both type 1 (T1D) and type 2 diabetes (T2D), although the underlying mechanisms differ: T1D is linked to autonomic neuropathy and disrupted transporter regulation, while T2D is often linked to medications and intestinal inflammation. Using streptozotocin-induced mouse models of T1D and T2D, we observed increased luminal fluid in the small intestine of both. Given the role of Na⁺/H⁺ exchanger 3 (NHE3) in fluid absorption and its loss in most diarrheal diseases, we examined NHE3 expression across intestinal segments.

Mapping Perceived Impact, Facilitators and Barriers of Cystic Fibrosis Management in Children and Adolescents: A Qualitative Study From the Parents' Perspective.

Background: Cystic fibrosis imposes a significant treatment burden on children and their informal caregivers, who have to change their routines to carefully adhere to medication and exercise as treatment regimes. Although informal caregivers are known to be key players in the daily management of these children, their own voice is scarcely explored, often hindering personalisation of care. The main objective of the study was to map the multifactorial impact of cystic fibrosis, as well as identify barriers and facilitators perceived by parental caregivers in managing the disease in the paediatric age.

Microenvironment-Driven Mast Cell Plasticity: Insights From Cytokine-Activated Gene Signatures in Skin and Respiratory Diseases.

Mast cells (MCs) rapidly adapt to the microenvironment due to the plethora of cytokine receptors expressed. Understanding microenvironment-primed immune responses is essential to elucidate the phenotypic/functional changes MCs undergo, and thus understand their contribution to diseases and predict the most effective therapeutic strategies. We exposed primary human MCs to cytokines mimicking a T1/pro-inflammatory (IFNγ), T2/allergic (IL-4 + IL-13), alarmin-rich (IL-33) and pro-fibrotic/pro-tolerogenic (TGFβ) microenvironment.
