Effects of a remotely supervised resistance training program on muscle strength and body composition in adults with cystic fibrosis: Randomized controlled trial.

Introduction: Among the limited studies on physical exercise interventions in adults with cystic fibrosis (CF), few have specifically addressed the improvement of peripheral muscle strength and body fat-free mass. The aim of this study was to examine the impacts of a remotely supervised, individualized 8-week resistance training program of moderate to high intensity on strength and body composition in these subjects.

Methods: This was a randomized controlled trial performed in adults with CF.

Mechanisms of ventilatory limitation to maximum exercise in children and adolescents with chronic airway diseases.

Introduction: Exercise intolerance is common in chronic airway diseases (CAD), but its mechanisms are still poorly understood. The aim of this study was to evaluate exercise capacity and its association with lung function, ventilatory limitation, and ventilatory efficiency in children and adolescents with cystic fibrosis (CF) and asthma when compared to healthy controls.

Methods: Cross-sectional study including patients with mild-to-moderate asthma, CF and healthy children and adolescents.

SARS-CoV-2 infection in children with cystic fibrosis: A cross-sectional multicenter study in Spain. New waves, new knowledge.

Introduction: The association between viral infections and pulmonary exacerbations in children with cystic fibrosis (cwCF) is well established. However, the question of whether cwCF are at a higher risk of COVID-19 or its adverse consequences remains controversial.

Methods: We conducted an observational, multicenter, cross-sectional study of cwCF infected by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) between March 2020 and June 2022, (first to sixth COVID-19 pandemic waves) in Spain.

Experience With Elexacaftor/Tezacaftor/Ivacaftor in Patients With Cystic Fibrosis and Advanced Disease.

Introduction: Elexacaftor/tezacaftor/ivacaftor (ETI) was used through the early access programme in Spain from December 2019 in cystic fibrosis (CF) patients with homozygous or heterozygous F508del mutation with advanced lung disease.

Methodology: Multicentre, ambispective, observational, study in which 114 patients in follow-up in 16 national CF units were recruited. Clinical data, functional tests, nutritional parameters, quality of life questionnaires, microbiological isolates, number of exacerbations, antibiotic treatments and side effects were collected.

Cost-effectiveness of omalizumab for the treatment of severe pediatric allergic asthma-Results of a real-life study in Spain.

Background: Severe pediatric allergic asthma (SPAA) induces a huge economic burden in terms of direct, indirect, and intangible costs. The use of omalizumab for the treatment of these patients has produced a significant improvement in several clinical outcomes, but at the same time, the cost for the management of the disease has also increased. The aim of this report was to evaluate whether the use of omalizumab is cost-effective.

Carbohydrate metabolism impairment in children and adolescents with cystic fibrosis.

Introduction: Development of cystic fibrosis-related diabetes (CFRD) is associated with worsening of nutritional status and lung function, as well as increased mortality. The relevance of diagnosing the «pre-diabetic» status in these patients has not been addressed and the utility of HbA1c measurement in these patients is under discussion.

Aim: To study and characterise the different categories of carbohydrate metabolism impairment in paediatric patients with cystic fibrosis.

Is exercise and electrostimulation effective in improving muscle strength and cardiorespiratory fitness in children with cystic fibrosis and mild-to-moderate pulmonary impairment?: Randomized controlled trial.

Background: Evidence on resistance-training programs for cystic fibrosis (CF) is limited and the possible benefits of the addition of neuromuscular electrical stimulation (NMES) are unknown. This study aimed to evaluate the effects of a supervised resistance-training program, associated or not with NMES, on muscle strength, aerobic fitness, lung function and quality of life in children with CF presenting mild-to-moderate pulmonary impairment.

Methods: This is a randomized controlled trial including CF patients aged between 6 and 17years.

Incidence and Prevalence of Children's Diffuse Lung Disease in Spain.

Background: Children's diffuse lung disease, also known as children's Interstitial Lung Diseases (chILD), are a heterogeneous group of rare diseases with relevant morbidity and mortality, which diagnosis and classification are very complex. Epidemiological data are scarce. The aim of this study was to analyse incidence and prevalence of chILD in Spain.

Comparison of physical fitness between healthy and mild-to-moderate asthmatic children with exercise symptoms: A cross-sectional study.

Objective: Asthma is a chronic disease that may affect physical fitness, although its primary effects on exercise capacity, muscle strength, functionality and lifestyle, in children and adolescents, are still poorly understood. This study aimed to evaluate the differences in cardiorespiratory fitness, muscle strength, lifestyle, lung function, and functionality between asthmatics with exercise symptoms and healthy children. In addition, we have analyzed the association between clinical history and the presence of asthma.

Effects of a Short-Term Resistance-Training Program on Heart Rate Variability in Children With Cystic Fibrosis-A Randomized Controlled Trial.

Cystic fibrosis (CF) affects the autonomic nervous system (ANS) and exercise in healthy children modulates the interaction between sympathetic and parasympathetic activity. This study aimed to evaluate the effects of a short-term resistance exercise program on heart rate variability (HRV) in children and adolescents with CF. A randomized controlled trial was carried out in children diagnosed with CF aged 6-18 years.

Omalizumab outcomes for up to 6 years in pediatric patients with severe persistent allergic asthma.

Background: Various studies have assessed omalizumab outcomes in the clinical practice setting but follow-up and/or number of patients included were limited. We aim to describe the long-term outcomes of pediatric patients with severe persistent allergic asthma receiving omalizumab in the largest real-life cohort reported to date.

Methods: ANCHORS was a multicenter, observational, retrospective cohort study conducted in 25 Pediatric Allergy and Pulmonology units in Spain.

Effect of a combined exercise program on physical fitness, lung function, and quality of life in patients with controlled asthma and exercise symptoms: A randomized controlled trial.

Background: Asthmatic patients may benefit from exercise training, although the effects of a combined aerobic and resistance training program are still poorly investigated in children and adolescents.

Objective: To analyze the effects of a combined exercise training (resistance and aerobic) program on aerobic fitness, lung function, asthma control and quality of life in a group of mild-moderate asthmatic children with exercise symptoms.

Methods: This was a 12-week randomized controlled trial including children and adolescents diagnosed with mild-moderate asthma and presenting exercise-induced symptoms.

Assessing the measurement of airway resistance by the interrupter technique.

Introduction: Pulmonary function tests allow an objective assessment of the degree of bronchial obstruction in collaborative subjects. The measurement of airway resistance using passive methods is very helpful in non-collaborative subjects. The objective of this study was to assess the applicability of measuring airway resistance by the interrupter technique (Rint) in pediatric subjects, determining its reproducibility, reliability and accuracy versus other techniques to measure airway resistance.

[Cystic adenomatoid malformation of the lung. Importance of prenatal diagnosis].

Cystic adenomatoid malformation of the lung is a rare malformation of the lung airway which often performed diagnosed in the prenatal period by ultrasound. Ultrasound monitoring should be performed during pregnancy to assess lung development. We report the case of a 4-year-old patient with prenatal diagnosis of cystic adenomatoid malformation of the lung, not confirmed by chest radiograph at birth.
