1. Percutaneous tracheostomy in COVID-19 patients: a new apneic approach
Abstract Background: Percutaneous dilation tracheostomy is an aerosol-generating procedure carrying a documented infectious risk during respiratory virus pandemics. For this reason, during the COVID-19 outbreak, surgical tracheostomy was preferred to the percutaneous one, despite the technique related complications increased risk. Methods: We describe a ne

2. Obstructive sleep apnea and Parkinson's disease: characteristics and associated factors
RESUMO A Apneia Obstrutiva do Sono (AOS) chega a acometer até 66% dos pacientes com doença de Parkinson (DP), prevalência maior, portanto, que a da população geral. Embora seja mais prevalente, a relação entre AOS e DP permanence controversa, com trabalhos confirmando e outros afastando a relação de AOS com alguns fatores de risco e sintomas em paci

3. The lung in paracoccidioidomycosis: new insights into old problems
OBJECTIVES: Chronic paracoccidioidomycosis can diffusely affect the lungs. Even after antifungal therapy, patients may present with residual respiratory abnormalities due to fungus-induced lung fibrosis. METHODS: A cross-sectional analysis of 50 consecutive inactive, chronic paracoccidioidomycosis patients was performed using high resolution computed tomo

4. Estudo da monitorização prolongada do pH esofágico em recém-nascidos pré-termo com suspeita clínica de doença do refluxo gastroesofágico / Esophageal pH monitoring of preterm newborns with clinically suspected gastro-esophageal reflux disease
Gastro-esophageal Reflux Disease (GERD) resulting from acid reflux can be diagnosed by prolonged esophageal pH monitoring. This examination in the preterm newborns (PTNBs) seeks to establish some relationship between GERD and nonspecific symptoms. This study aimed to evaluate the esophageal pH monitoring in PTNBs hospitalized with clinically suspected of GER

5. Desaturation - distance ratio: a new concept for a functional assessment of interstitial lung diseases
INTRODUCTION: The functional evaluation has become increasingly important in the understanding and management of patients with interstitial lung diseases. The cardiopulmonary exercise test and the six-minute walk test (6MWT), through their isolated variables, have been used to do this evaluation, with some limitations. OBJECTIVES: We proposed a new composite

6. Preditores da dessaturação do oxigênio no teste da caminhada de seis minutos em pacientes com fibrose cística / Predictors of oxygen desaturation during the six-minute walk test in patients with cystic fibrosis
Identificar os fatores preditores de dessaturação de oxigênio durante o teste de caminhada de seis minutos (TC6) em pacientes com fibrose cística (FC). Métodos: Estudo transversal e prospectivo em pacientes com FC clinicamente estáveis com idade superior a 10 anos. Os pacientes foram submetidos à avaliação nutricional, teste oral de tolerância à g

7. Comparação das respostas fisiológicas no teste de exercício cardiopulmonar e em três testes de exercício submáximo em pacientes com doença pulmonar obstrutiva crônica / Comparison of physiological responses to the cardiopulmonary exercise test and to three submaximal exercise tests in patients with chronic obstructive pulmonary disease
INTRODUÇÃO: A doença pulmonar obstrutiva crônica (DPOC) apresenta obstrução crônica ao fluxo aéreo e evolui com perda da capacidade funcional. A intolerância ao exercício é um marcador prognóstico da doença. OBJETIVO: Investigar as respostas fisiológicas no teste incremental com cicloergômetro (TECP), teste do degrau de 6 minutos (TD6), teste

8. Heart Rate Variability in Patients with Chronic Obstructive Lung Disease and Nocturnal Oxygen Desaturation / Análise da Variabilidade da Freqüência Cardíaca em Pacientes Portadores de Doença Pulmonar Obstrutiva Crônica e Dessaturação Noturna
Background: The autonomic nervous system may be disturbed in chronic respiratory failure. Chronic hypoxemia may result in sympathetic activation. There are few studies showing the role of the autonomic nervous system in patients with chronic obstructive lung disease (COPD) and nocturnal oxygen desaturation. Objective: To analyze the sympathetic and parasympa

9. Comparação de diferentes testes funcionais e suas relações com estado funcional e qualidade de vida em indivíduos com doença pulmonar obstrutiva crônica (DPOC)
Objectives: to evaluate and compare the responses to the various functional tests, and the concordance between the six-minute walk test in hallway (6MWT) and the of oval track (6MWToT), of treadmill (6MWTT), and of treadmill with inclination (6MWTTI), the six-minute step test (6MST) and the two-minute chair test (2MCT), in patients with Chronic Obstructive P

10. AvaliaÃÃo dos parÃmetros cardiovasculares em pacientes submetidos à sedaÃÃo consciente com Ãxido nitroso / Evaluation of cardiovascular parameters of patients under conscious sedation with nitrious oxide,
Fear is a fundamental human emotion. It is fear that triggers physiological responses that prepare the body for action against real or imaginary threats, allowing the individual to decide whether to fight or flee. When fear, or resulting anxiety, interferes with the provision of healthcare causing patients to delay or avoid care, it is necessary to take meas

11. Fatores preditivos de dessaturação de oxigênio em pacientes submetidos à colangiopancreatografia endoscópica retrógrada sob sedação consciente / Predictive factors of oxygen desaturation of patients submitted to the endoscopic retrograde cholangiopancreatography under conscious sedation
A hipoxemia pode ocorrer durante a Colangiopancreatografia Endoscópica Retrógrada (CPER) porque alguma analgesia e sedação precisam ser realizadas. O posicionamento do paciente em pronação dificulta a ventilação adequada. Um estudo transversal controlado foi utilizado para investigar possíveis fatores preditivos de dessaturação de oxigênio em pac

BACKGROND: A high prevalence of Obstructive sleep apnea (OSA) has been reported in patients with coronary artery disease (CAD). Several OSA related mechanisms, such as oxygen desaturation, high sympathetic activity, increased cardiac oxygen demand and a prothrombotic state, may be particularly dangerous in acute CAD patients. Nevertheless, OSA is frequently
