Article Synopsis
  • Primary ciliary dyskinesia (PCD) is a rare genetic disorder that affects ciliary function, leading to airway clearance issues and sometimes organ positioning defects (laterality defects), with a study conducted across 19 countries to analyze gene defects and their clinical implications.
  • The study involved 1236 individuals with a variety of pathogenic DNA variants and found significant geographical differences in PCD genotypes, with varying rates of laterality defects and distinct genetic characteristics linked to different countries.
  • Results revealed that individuals with PCD often have lower lung function (measured by forced expiratory volume) and that the presence of certain genetic variants can correlate with more severe clinical outcomes, highlighting the importance of genetic understanding in diagnosing

Introduction: The cerbations of hronic obstructive lung disease (COPD) and their utcome (EXACOS) International Study aimed to quantify the rate of severe exacerbations and examine healthcare resource utilisation (HCRU) and clinical outcomes in patients with COPD from low-income and middle-income countries.

Methods: EXACOS International was an observational, cross-sectional study with retrospective data collection from medical records for a period of up to 5 years. Data were collected from 12 countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Guatemala, Hong Kong, Mexico, Panama, Russia and Taiwan.

Objective: To evaluate the effect of treatment with the combination of three cystic fibrosis transmembrane conductance regulator (CFTR) modulators-elexacaftor+tezacaftor+ivacaftor (ETI)-on important clinical endpoints in individuals with cystic fibrosis.

Methods: This was a systematic review and meta-analysis of randomized clinical trials that compared the use of ETI in individuals with CF and at least one F508del allele with that of placebo or with an active comparator such as other combinations of CFTR modulators, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations and the Patients of interest, Intervention to be studied, Comparison of interventions, and Outcome of interest (PICO) methodology. We searched the following databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and ClinicalTrials.

Background: Consistent use of reliable and clinically appropriate outcome measures is a priority for clinical trials, with clear definitions to allow comparability. We aimed to develop a core outcome set (COS) for pulmonary disease interventions in primary ciliary dyskinesia (PCD).

Methods: A multidisciplinary international PCD expert panel was set up.

 Primary ciliary dyskinesia (PCD) is a rare inherited disease associated with impairment of mucociliary transport and, consequently, with a high incidence of chronic rhinosinusitis. For patients with chronic rhinosinusitis who remain symptomatic despite medical treatment, endoscopic sinus surgery is a safe and effective therapeutic option. However, to date, no studies have been found evaluating the effect of surgery on the quality of life associated with the effect on olfaction and nasal endoscopy findings of patients with primary ciliary dyskinesia and chronic rhinosinusitis.

Cystic fibrosis (CF) is a genetic disease that results in dysfunction of the CF transmembrane conductance regulator (CFTR) protein, which is a chloride and bicarbonate channel expressed in the apical portion of epithelial cells of various organs. Dysfunction of that protein results in diverse clinical manifestations, primarily involving the respiratory and gastrointestinal systems, impairing quality of life and reducing life expectancy. Although CF is still an incurable pathology, the therapeutic and prognostic perspectives are now totally different and much more favorable.

 Primary ciliary dyskinesia is a rare inherited disease that results in a malfunction of mucociliary clearance and sinonasal complaints. Aplasia/hypoplasia of the frontal and sphenoid sinuses has been described as more frequent in this population. However, to date, no studies have provided a detailed description of computed tomography findings in adult patients with a diagnosis of this condition.

Objective: To assess the prevalence of the eosinophilic and allergic phenotypes of severe asthma in Brazil, as well as to investigate the clinical characteristics of severe asthma patients in the country.

Methods: This was a cross-sectional study of adult patients diagnosed with severe asthma and managed at specialized centers in Brazil. The study was conducted in 2019.

Objective: To develop a scientific consensus on nutrition in cystic fibrosis.

Methods: Sixteen coordinators elaborated relevant questions on nutritional therapy in cystic fibrosis, which were divided into six sections: nutritional assessment, nutritional recommendations, nutritional intervention, dietary counseling, special situations and enzyme replacement, and gastrointestinal manifestations. Two to three specialists in the field were responsible for each section and obtaining answers formulated based on standardized bibliographic searches.

Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in patients with cancer. On the basis of results from randomized controlled trials, direct oral anticoagulants (DOACs) are now recommended for the treatment of cancer-associated VTE. The decision to use a DOAC requires consideration of bleeding risk, particularly in patients with gastrointestinal (GI) malignancies, the cost-benefit and convenience of oral therapy, and patient preference.

Aim: To investigate the short- and long-term effects of home-based pulmonary rehabilitation (HBPR) on functional capacity, quality of life, peripheral muscle strength, dyspnoea and daily physical activity in people with bronchiectasis.

Methods: Randomised controlled trial with 63 participants with bronchiectasis. The HBPR group performed three sessions per week for 8 weeks (aerobic exercise: step training for 20 min; resistance training: exercises for quadriceps, hamstrings, deltoids and biceps brachii using elastic bands).

Objectives: To compare the inflammatory and oxidative stress (OS) states of adults with bronchiectasis with those of healthy controls and correlate inflammatory and OS levels with lung function and physical capacity.

Methods: This study used a cross-sectional design. Seventy-four adults with bronchiectasis (age: 49±15 years, forced expiratory volume in 1 second [FEV1]: 52.

Objective: To investigate the validity of field walking tests to identify exercise-induced hypoxemia and to compare cardiorespiratory responses and perceived effort between laboratory-based and field-based exercise tests in subjects with bronchiectasis.

Methods: This was a cross-sectional study involving 72 non-oxygen-dependent participants (28 men; mean age = 48.3 ± 14.

Article Synopsis
  • The study explores the ethnic diversity in Brazil and its impact on the distribution of CFTR gene variants in individuals with cystic fibrosis (CF) across different regions.
  • The research used Next Generation Sequencing to analyze the genotyping of over 4,600 CF individuals, revealing significant regional differences in positive, inconclusive, and negative genotyping results.
  • Findings indicate that socio-economic factors, inadequate newborn screening, and limited access to reliable testing contribute to these discrepancies, highlighting regions in Brazil that require improved CF care.

Article Synopsis
  • Mounier-Kuhn syndrome, a rare condition, features significant dilation of the trachea and bronchi which leads to symptoms like cough, difficulty breathing, and frequent respiratory infections; current treatments are varied and lack consensus.
  • The study aims to identify tracheobronchomalacia, determine the best CPAP pressure to minimize airway collapse in Mounier-Kuhn patients, and evaluate the prevalence of sleep apnea.
  • A clinical trial will involve three outpatient visits to collect data, perform sleep studies, assess airway collapse, and conduct imaging tests to analyze the effectiveness of CPAP pressure adjustments.
