TRACK: Validation of the Portuguese Version

AsthmaRespiratory Disease

The TRACK ("Test for Respiratory and Asthma Control in Kids") questionnaire is a validated instrument to evaluate the control of respiratory symptoms in young children. The TRACK questionnaire was developed in English and a version in Portuguese is not available or validated, purpose of the present project.

Diagnostic Accuracy Of Forced Oscillation Technique To Detect Lung Function Anomalies

Respiratory Disease

The diagnosis of a lung function anomaly requires the evaluation of pulmonary function by spirometry. However, some patients (e.g. children, elderly, or diseased individuals) may have difficulty performing the related forced maximal respiratory maneuver correctly. Forced Oscillation Technique (FOT) measures lung impedance during tidal breathing, requiring minimal patient cooperation. The purpose of this study is to establish the diagnostic accuracy of FOT parameters alone or in combination with lung volumes in detecting lung function anomalies as compared with spirometry and with the diagnosis made by the physician.

Within-Breath Total Respiratory Input Impedance in Healthy Adult Subjects

Respiratory Disease

Assessment of lung function requires the evaluation of pulmonary function by spirometry. However, some patients (e.g. children, elderly, or diseased individuals) may have difficulty performing the related forced maximal respiratory maneuver correctly. Forced oscillation technique (FOT) is increasingly being used in clinical settings to evaluate lung function noninvasively by measuring the mechanical input impedance of the respiratory system. FOT measures lung impedance during tidal breathing, requiring minimal patient cooperation. Recently a new methodology (within breath analysis) has emerged to evaluate changes that occur in the impedance during the breathing activity. The within-breath calculation of impedance allows separating the contribution of inspiration and expiration to the measured parameters. The purpose of this study is to establish reference ranges for within breath FOT parameters and their short term variability.

Artificial Intelligence in Diagnosing Dysphagia Patients

Respiration DisordersSwallowing Disorder4 more

In this prospective study we extracted acoustic parameters using PRAAT from patient's attempt to phonate during the clinical evaluation using a digital smart device. From these parameters we attempted (1) to define which of the PRAAT acoustic features best help to discriminate patients with dysphagia (2) to develop algorithms using sophisticated ML techniques that best classify those i) with dysphagia and those ii ) at high risk of respiratory complications due to poor cough force.

Cardiorespiratory Diagnostic Study

COPDAsthma8 more

This study uses a new breathing device called 'N-Tidal C' handset which measures breathing patterns. Investigators have found that people with cardiac and respiratory illnesses breathe out a gas, called carbon dioxide (CO2), in a different way to healthy people. The pattern of breathed out CO2 (the waveform) varies according to the underlying health of the user's lungs. Monitoring these changes may help doctors to more accurately diagnose and monitor the most common and serious respiratory conditions.

Research on the Application and Mechanism of New Biological Probes in Biomedicine

TumorsCardiovascular Diseases9 more

Fluorescence is one of the most commonly used research and detection techniques in the field of biomedical science. The characteristics of fluorescent probe directly affect the performance and application of fluorescence analysis and imaging. Aggregation-Caused Quenching has limited the application of traditional fluorescent probes to some extent. This project intends to systematically evaluate the detection efficiency of new methods through the detection of biomarkers in clinical samples and the comparison with the detection methods of traditional biomarkers, so as to provide theoretical and experimental basis for the establishment of fast and simple biomarker detection technologies with new biological probes.
