Diffuse Parenchymal Lung DiseasesThe purpose of this study is to generate a prospective database of all patients evaluated for diffuse parenchymal lung diseases to provide much needed data on the various disease aetiologies, incidence and prevalence rates, clinical and radiological presentations, pathologic correlations, disease progression and response to treatment, and final outcomes in this group of patients in Singapore.
Assessment of Continuous Measurement of Transcutaneous CO2 for Evaluation of Alveolar Dead Space...
Pulmonary DiseaseChronic Obstructive6 moreThe study aim is to monitor, during exercise tests carried out in various conditions, the alveolar dead space, by means of continuous transcutaneous measurement of Pt CO2, which would be used as a surrogate for arterial PaCO2. Validity of this measurement needs to be assessed against arterial sampling (either arterial, or arterialized capillary), especially with regards to the lag time required by the CO2 diffusion from the arterial compartment (PaCO2) to the cutaneous one (PtCO2), in particular when rapid changes of CO2 might be induced by exercise. The evaluation will be done in 2 different settings: intensive care patients, equipped, for their routine clinical care, with an arterial line; this allows for a precise timed comparison between PaCO2 and PtCO2 readouts; routine exercise test, where blood gas evaluation is done essentially by means of arterialized earlobe capillary sampling. Following assessment of validity of the measurement (and the lag time PaCO2-PtCO2 which might be necessary to introduce as a correction), evolution of dead space during excise test will be tested in different conditions: Healthy subjects, patients with Chronic Obstructive Pulmonary Disease (COPD), chronic heart failure (CHF), hyperventilation, Pulmonary artery hypertension (PAH), or interstitial lung disease (ILD)
Outcomes of RV Dysfunction in Acute Exacerbation of Chronic Respiratory Diseases
Acute Exacerbation of COPDAcute Exacerbation of Bronchiectasis5 moreObservational study in patients with chronic respiratory diseases (chronic obstructive pulmonary diseases, bronchiectasis, interstitial lung diseases, neuromuscular diseases, obesity-hypoventilation syndrome...) admitted in intensive care unit for acute respiratory failure. The main objective is to determine the prevalence of right ventricular (RV) dysfunction in this population and to analyze the impact of such a complication on outcomes (survival at day-28, duration of non-invasive or mechanical ventilation, duration of hospital stay). RV function will be assessed by echocardiography at admission, after 3 days and at discharge. Plasma NT-proBNP and troponin levels will be collected.

Interstitial Lung DiseaseChronic Kidney DiseasesThis is a Phase I, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of a 10 mg/kg dose of AD-214 when administered to healthy volunteers (HVs) (Part A) or patients with interstitial lung disease (ILD) or chronic kidney disease (CKD) (Part B). The study will be performed in Australia at up to two clinical sites.
Ultra-Low Dose Computed Tomography For Diagnosis And Follow-Up Of Patients With Diffuse Parenchymal...
Diffuse Parenchymal Lung DiseaseThe primary intention of this study is to determine the diagnostic performance of ultra-low-dose CT (ULDCT) in diagnosis and follow-up of diffuse parenchymal lung disease (DPLD). We hypothesize that inspiratory and expiratory chest ULDCT has comparable diagnostic yield to standard dose chest High-resolution computed tomography (HRCT) and utility for follow-up of patients with known DPLD. We will study this hypothesis through the following aims: Determine whether inspiratory and expiratory ULDCT are comparable to HRCT in identifying mosaic attenuation due to air-trapping. Determine whether ULDCT is as good as HRCT for follow-up of patients with established DPLD to identify disease progression.
Cough Capture as a Portal Into the Lung
Lung DiseasesLung Cancer5 moreBackground: The lung is a privileged organ; blood does not reflect most lung processes well, if at all. Therefore, for population scale diagnostics, the investigator team is developing non-invasive portals to the lung, for eventual early detection/risk assessment and diagnostic purposes. However, large macromolecules are not likely suspended nor readily detected in the breath. In particular, genomic DNA in the breath condensate (EBC) is very sparse, and where present, generally highly fragmented, not readily amenable to sequencing based assessments of DNA somatic mutation burden or distribution. Because gDNA (and protein) is challenging to obtain non-invasively from EBC, the study team considered alternative surrogate lower airway specimens. Cough capture is rarely done, and the investigator team is in the process of optimizing its collection. Importantly, the team will be evaluating how much of coughed material is from saliva contamination. Additionally, analyzing material that is target captured by capturing deep lung extracellular vesicles (EVs) using immobilized CCSP/SFTPC antibodies targeting EVs from distal bronchiole Club and alveolar type 2 cells could circumvent the mouth contamination problem, leaving a non-invasive portal to the deep lung suitable for large molecules, and in turn suitable for myriad epidemiologic and clinical applications. Proposal: The investigator team proposes (Aim 1) to pursue optimizing cough collection, and testing the efficacy and practicality of partitioning cough specimen for deep-lung specific extra-cellular vesicles (EVs). This cough specimen will be compared to that from invasively collected deep lung samples BAL/bronchial brushings, and to the potential contaminating mouthrinse, all from the same individuals. (Aim 2) The study team initially proposes to examine these cough specimens for somatic mutations by SMM bulk sequencing for single nucleotide variation, developed in the Vijg/Maslov labs. Finally, the investigator team will (Aim 3) test all airway specimens (cough, mouthwash and BAL) for lung surrogacy of cough, using proteins known to be specific for lung, as opposed to oral cavity/saliva, in the Sidoli/proteomics core. Impact: The investigator team envisions that the translational impact of non-invasively obtained DNA or protein markers could allow for more rapid acute clinical diagnoses, and facilitate precision prevention and/or early detection of many acute and chronic respiratory disorders, including lung cancer, asthma and COPD, acute and chronic infectious diseases, and indeed systemic disorders of inflammation and metabolism.
ILD: Health Outcomes in Remote Digital Monitoring Versus Usual Care
Interstitial Lung DiseaseInterstitial lung disease (ILD) is a collective term for a group of diseases where the lungs become scarred causing breathlessness. This research project will assess if remote digital monitoring of frequent spirometry and pulse oximetry can provide an additional way to monitor ILD and provide information to support virtual consultations. Outcomes in the remote monitoring group will be compared with usual care alone over 12 months. Patients taking part will be randomly allocated to remote digital monitoring or to usual care (with an equal chance of either). Remote monitoring will be performed using an app provided by patientMpower Ltd which patients will be able to download onto a smartphone or tablet. The study team will provide a spirometer and oximeter for patients to measure their lung function (spirometry) and oxygen saturations. These devices link to the app via Bluetooth to record all measurements. Patients will be asked to do these measurements three times a week. Clinical teams will be asked to review all measurements at least once a fortnight. Health outcomes will be described and compared between the two groups.

Move With Air: Exercise Training Study
Chronic Obstructive Pulmonary DiseaseInterstitial Lung Disease1 moreThe purpose of this study is to explore the role of a stream of cool air to the face, through fan-to-face therapy, as a novel adjunct non-pharmacological therapy to enable symptomatic adults with cardiopulmonary disease to exercise at higher intensities for longer durations and maximize the psycho-physiological benefits of a supervised exercise training program. The investigators hypothesize that, compared to no fan, fan-to-face therapy will result in relatively greater improvements in exercise endurance time and intensity ratings of perceived breathlessness during constant-load cardiopulmonary exercise testing on a treadmill at 75% of peak power output.
