1. Panic disorder respiratory subtype: psychopathology and challenge tests – an update
Panic disorder (PD) pathophysiology is very heterogeneous, and the discrimination of distinct subtypes could be very useful. A subtype based on respiratory symptoms is known to constitute a specific subgroup. However, evidence to support the respiratory subtype (RS) as a distinct subgroup of PD with a well-defined phenotype remains controversial. Studies hav

2. Ventilation distribution as a contributor to the functional exercise capacity in patients with systemic sclerosis-associated interstitial lung disease without pulmonary hypertension
Phenotypic differences have been described between patients with systemic sclerosis (SSc)-associated interstitial lung disease (ILD) and SSc-associated pulmonary hypertension, including performance differences in the 6-min walk test (6MWT). Moreover, the correlations between the 6MWT and traditional pulmonary function tests (PFTs) are weak, indicating the ne

3. A detailed comparison of oxygen uptake kinetics at a range of exercise intensities
Abstract Aim: The aim of this study was to comprehensively examine oxygen uptake (V̇O2) kinetics during cycling through mathematical modeling of the breath-by-breath gas exchange responses across eight conditions of unloaded cycling to moderate to high-intensity exercise. Methods: Following determination of GET and V̇O2peak, eight participants (age: 24±

4. Nitrogen single-breath washout test for evaluating exercise tolerance and quality of life in patients with chronic obstructive pulmonary disease
Pulmonary function tests (PFTs) traditionally used in clinical practice do not accurately predict exercise intolerance in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to assess whether the nitrogen single-breath washout (N2SBW) test explains exercise intolerance and poor quality of life in stable COPD patients. This c

5. Assessment of the accuracy of portable monitors for halitosis evaluation in subjects without malodor complaint. Are they reliable for clinical practice?
Abstract Halitosis is defined as a foul odor emanated from the oral cavity, with great impact in quality of life and social restraints. Recently, the use of Breath Alert™ in research increased significantly. Halimeter™, another portable device, is often used in clinical practice. Nevertheless, not many studies have verified the accuracy and compared the

6. Relationship between ventilation heterogeneity and exercise intolerance in adults with sickle cell anemia
Sickle cell anemia (SCA) causes dysfunction of multiple organs, with pulmonary involvement as a major cause of mortality. Recently, there has been growing interest in the nitrogen single-breath washout (N2SBW) test, which is able to detect ventilation heterogeneity and small airway disease when the results of other pulmonary function tests (PFTs) are still n

7. Cerebral vasomotor reactivity assessment using Transcranial Doppler and MRI with apnea test
Differently from previous studies that used Transcranial Doppler (TCD) and functional MRI (fMRI) for cerebral vasomotor reactivity (CVR) assessment in patients with carotid stenosis (CS), we assessed CVR using an identical stimulus, the Breath-Holding Test (BHT). We included 15 patients with CS and 7 age-matched controls to verify whether fMRI responded diff

8. Association between respiratory and postural adaptations and self-perception of school-aged children with mouth breathing in relation to their quality of life
Objective: To investigate the respiratory and postural adaptations associated with mouth and nasal breathing and to evaluate the associations of such adaptations in mouth breathers' self-perceived quality of life. Method: Cross-sectional study with mouth breathers (initial n=116 and final n=48) and nasal breathers (initial n=131 and final n=24) from element

9. Histological and endoscopic features of the stomachs of patients with Chagas disease in the era of Helicobacter pylori
Introduction Most studies that have evaluated the stomachs of patients with Chagas disease were performed before the discovery of Helicobacter pylori and used no control groups. This study compared the gastric features of chagasic and non-chag

10. Differences in muscle strength after ACL reconstruction do not influence cardiorespiratory responses to isometabolic exercise
Objectives: To investigate whether the muscle strength decrease that follows anterior cruciate ligament (ACL) reconstruction would lead to different cardiorespiratory adjustments during dynamic exercise. Method: Eighteen active male subjects were submitted to isokinetic evaluation of knee flexor and extensor muscles four months after ACL surgery. Thigh c

11. Avaliação de parâmetros funcionais respiratórios em pacientes adultos infectados pelo HIV / Evaluation of functional respiratory parameters in HIV infected adult patients
Background: Pulmonary function, in HIV infected patients, has been associated with reduction in pulmonary ventilation parameters Methods: We conducted a sectional study to evaluate the pulmonary function of AIDS patients cared for in the infectious diseases ambulatories. Maximal inspiratory (MIP) and expiratory (MEP) pressures and spirometry were assessed. C

12. Análise dos tempos de apneia voluntária máxima como teste de função pulmonar em pacientes com distúrbios ventilatórios obstrutivos e normais / Analysis of the maximal voluntary breath-holding time as pulmonary function tests in patients with obstructive ventilatory defects and normal controls
Introdução: O teste de apneia respiratória tem sido testado e demonstrou ser de utilidade clínica. Objetivos: Determinar o tempo de apneia voluntária máxima em pacientes com distúrbios ventilatórios obstrutivos (DVO) e em indivíduos normais e correlacionar os tempos de apneia com os testes de função pulmonar. Métodos: Foi realizado um estudo caso
