Feasibility of performing the 3-minute step test with remote supervision in children and adolescents with cystic fibrosis: A comparative study.

Importance: The 3-min step test is a simple option to monitor submaximal exercise capacity, although its use via remote video monitoring has not been investigated in children with cystic fibrosis (CF).

Objective: This study aimed to assess the feasibility and reproducibility of performing the 3-min step test with remote supervision.

Methods: A cross-sectional study including CF patients (6-18 years) from two CF services were performed.

Clinical use of the modified shuttle test in children with cystic fibrosis: Is one test sufficient?

Objective: To evaluate the reproducibility of the modified shuttle test (MST) and to determine whether the test needs to be performed more than once to assess the exercise capacity of children and adolescents with cystic fibrosis (CF).

Methods: This was a longitudinal study including patients diagnosed with CF aged more than 6 years. The participants were followed for a period of 9 months and were evaluated at three different time points (visits 1, 2, and 3).

FUNCTIONAL PERFORMANCE IN THE MODIFIED SHUTTLE TEST IN CHILDREN AND ADOLESCENTS WITH CYSTIC FIBROSIS.

Objective: To evaluate factors associated with the performance of children and adolescents with cystic fibrosis (CF) in the Modified Shuttle Test (MST) and compare it with healthy children and adolescents.

Methods: This is a cross-sectional study, with children and adolescents divided into two groups: cystic fibrosis (CFG) and control (CG). Variables evaluated in the MST: walking distance, test level, heart rate variation (∆Hr), post-test mean arterial pressure (MAP Pt) and peripheral oxygen saturation variation (∆SPO2).

Tissue oxygenation in peripheral muscles and functional capacity in cystic fibrosis: a cross-sectional study.

New Findings: What is the central question of this study? How do peripheral muscle tissue oxygenation and physical conditioning levels of children and adolescents with cystic fibrosis compare to demographically matched controls? What is the main finding and its importance? Children and adolescents with cystic fibrosis consumed more oxygen, more quickly and exhibited slower recovery, demonstrating that there may have been deficiencies in oxygen supply related to both oxygen uptake and oxygen transport.

Abstract: Cystic fibrosis affects skeletal muscle performance and functional capacity. However, it is currently unclear how peripheral muscle behaviour is affected, especially in children and adolescents.

Respiratory physical therapy techniques recommended for patients with cystic fibrosis treated in specialized centers.

Background: Respiratory therapy is a part of the treatment of patients with cystic fibrosis (CF). However, there is no information about the main factors influencing the recommendation of the use of different techniques or devices by physical therapists from different specialized centers.

Objective: To determine the respiratory therapy techniques recommended for the treatment of patients with CF seen in specialized treatment centers in Brazil.

Microbiological contamination of nebulizers used by cystic fibrosis patients: an underestimated problem.

Objective: Home nebulizers are routinely used in the treatment of patients with cystic fibrosis (CF). This study aims to evaluate the contamination of nebulizers used for CF patients, that are chronically colonized by Pseudomonas aeruginosa, and the association of nebulizer contamination with cleaning, decontamination and drying practices.

Methods: A cross-sectional, observational, multicenter study was conducted in seven CF reference centers in Brazil to obtain data from medical records, structured interviews with patients/caregivers were performed, and nebulizer's parts (interface and cup) were collected for microbiological culture.

Comparative analysis and reproducibility of the modified shuttle walk test in normal children and in children with cystic fibrosis.

Objective: To analyze the shuttle walk test, and its respective retest, comparing children with cystic fibrosis (CF) to normal children.

Methods: The children were divided into two groups: the CF group, composed of children in whom the diagnosis had been confirmed through sweat testing; and the control group, composed of normal children with no history of pulmonary diseases and no alterations in respiratory function. The children were submitted to at least two consecutive tests, 30 min apart.
