Journalistic media and adolescents in the COVID-19 pandemic: a documental analysis.

Objective: To analyze how the journalistic media has described the issues of quality of life (QoL), physical activity (PA) and mental health (MH) of adolescents during the COVID-19 pandemic.

Methods: This is a descriptive and qualitative study that used content analysis. Sixty-two journalistic publications were analyzed from a total of 8211 published by the most read newspapers in each Brazilian region between December 2019 and August 2021.

Single breath counting technique to assess pulmonary function: a systematic review and meta-analysis.

Pulmonary function is usually assessed by measuring Vital Capacity (VC) using equipment such as a spirometer or ventilometer, but these are not always available to the population, as they are relatively expensive tests, difficult to transport and require trained professionals. However, the single breath counting technique (SBCT) appears as a possible alternative to respiratory function tests, to help in the pathophysiological understanding of lung diseases. The objective is to verify the applicability of the SBCT as a parameter for evaluating VC.

Can physical exercise assist in controlling and reducing the severity of exercise-induced bronchospasm in children and adolescents? A systematic review.

Objective: The aim of this study was to analyze whether physical exercise can contribute to improving the control and severity of exercise-induced bronchospasm (EIB) in children and adolescents.

Method: This is a systematic review that used PubMed/Medline and Scopus databases as a search source, and using descriptors indexed to DeCS/Mesh. The articles were analyzed in three stages in the selection process.

Comparison between impulse oscillometry parameters and spirometry for the diagnosis of exercise-induced bronchoconstriction in asthmatic children and adolescents.

Introduction: Impulse oscillometry (IOS) parameters are obtained more easily and effortlessly in comparison to forced expiratory volume in the first second (FEV1).

Objective: To compare IOS parameters to FEV1 in exercise-induced bronchoconstriction (EIB) diagnosis.

Methods: Seventy-four (60.

Accuracy of peak nasal flow to determine nasal obstruction in patients with allergic rhinitis.

Objective: The aim of this study was to investigate the ability of Peak Nasal Inspiratory Flow (PNIF) and Peak Nasal Expiratory Flow (PNEF) measures to predict symptoms of nasal obstruction.

Methods: This is a cross-sectional study, carried out in 131 individuals (64 with symptomatic allergic rhinitis and 67 asymptomatic) aged between 16 and 50 years.

Results: PNIF and PNEF were higher among non-rhinitis.

Respiratory burden in obese and young asthmatics: a study of diaphragmatic kinetics.

Objective: The aim of this study was to assess the diaphragm kinetics, respiratory function, and serum dosage of leptin and inflammatory cytokines (IL-6 and TNF-α) in three clinical groups: obese, asthmatic, and healthy.

Methods: This is a clinical exploratory study performed on 73 youths (12-24 years of age, 42.5% male) allocated into three groups: obesity (OG, n=33), body mass index (BMIz-score) ≥ +2, asthmatic (AG, n=26) controlled mild asthmatics, classified by GINA, and Healthy Control Group (CG, n=14).

Impact of climate variability on exercise-induced bronchospasm in adolescents living in a semi-arid region.

Objective: To examine the impact of climate variability on the occurrence of exercise-induced bronchospasm in the rainy and dry seasons of a Brazilian semi-arid region.

Methods: This sample comprised 82 adolescents aged 15 to 18 years, who were submitted to exercise-induced bronchospasm assessment on a treadmill and outdoors, during the rainy and the dry season. Anthropometric variables, sexual maturity and forced expiratory volume in the first second were analyzed.

Reproducibility of eucapnic voluntary hyperpnoea for exercise-induced bronchoconstriction diagnosis in asthmatic children and adolescents.

Background: Respiratory symptoms after exercise are frequently reported by asthmatic patients, and exercise-induced bronchoconstriction (EIB) is a frequent cause, which requires objective testing for diagnosis. Eucapnic voluntary hyperpnea (EVH) is recommended as a surrogate stimulus for this purpose. Its short-term reproducibility is not yet established in children and young adolescents with asthma.

PHYSICAL ACTIVITY LEVEL IN ASTHMATIC ADOLESCENTS: CROSS-SECTIONAL POPULATION-BASED STUDY.

Objective: To assess the level of physical activity in asthmatics in comparison with non-asthmatics in a population study.

Methods: Cross-sectional study with 13 to 14-year-old adolescents who participated in the International Study of Asthma and Allergies in Childhood (ISAAC). The subjects were classified into three groups: individuals with active asthma, individuals diagnosed with asthma, and respiratory asymptomatic individuals.

Exercise-induced bronchospasm in children and adolescents with allergic rhinitis by treadmill and hyperventilation challenges.

Background: Respiratory complaints after exercise are common in patients with rhinitis. Exercise-induced bronchospasm (EIB) may be one of the causes.

Objectives: To evaluate EIB prevalence in a group of children and adolescents with allergic rhinitis, to compare the treadmill running (TR) and eucapnic voluntary hyperventilation (EVH) challenge methods as diagnostic tools and to assess the association between respiratory complaints on exercise and EIB.

Exercise-induced bronchospasm in a hot and dry region: study of asthmatic, rhinitistic and asymptomatic adolescents.

Background: Exercise-induced bronchospasm (EIB) is the bronchial narrowing that occurs after intense exercise in a significant number of asthmatics and in some non-asthmatics. This study aims to evaluate the occurrence of EIB in adolescents with asthma, rhinitis and respiratory asymptomatics in a hot and dry climate.

Research Design And Methods: This is a cross-sectional study based on an epidemiological study that evaluated the prevalence of asthma in schoolchildren in a semi-arid zone of Brazil.

Lower prevalence and greater severity of asthma in hot and dry climate.

Objective: To estimate asthma prevalence, severity, and associated factors in adolescents who live in a low relative humidity environment.

Methods: In this cross-sectional study, adolescents aged 13-14 years from the city of Petrolina located in the Brazilian semiarid region answered the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. The possible explanatory variables of the study were gender, family income, mother's education, smokers in the household, parental history of asthma, personal history of allergic rhinitis or atopic dermatitis, and physical activity level.

Expiratory peak flow and respiratory system resistance in mechanically ventilated patients undergoing two different forms of manually assisted cough.

Objective: Mechanical ventilation is associated with retained airway secretions. Manually assisted cough contributes to the displacement of bronchial mucus, whereas positive end-expiratory pressure increases collateral ventilation and maintains airway patency. This study aimed to assess the effects of manually assisted cough, either alone or added to increased positive end-expiratory pressure and inspiratory time (optimized manually assisted cough), on the expiratory peak flow and respiratory system mechanics in mechanically ventilated patients.

Noise in the intensive care unit: quantification and perception by healthcare professionals.

Objective: The several multidisciplinary team personnel and device alarms make intensive care units noisy environments. This study aimed to measure the noise level of a medical-surgical intensive care unit in Recife, Brazil, and to assess the noise perception by the unit's healthcare professionals.

Methods: A decibel meter was used for continuous every five seconds one week noise levels recording.
