Data Collection Using Eko Digital Devices in a Clinical Setting

The purpose of this research is to prospectively train and validate an artificial intelligence machine learning (ML) algorithm to detect the presence of adventitious lung sounds in adults. Clinicians will use the Eko CORE and/or Eko CORE 500 device(s) in real clinical settings to collect normal and abnormal lung sounds, as part of standard of care clinical practice, which will then be used to explore an ML algorithm for classifiers for wheeze, coarse crackle, fine crackle, rhonchus, stridor, rales, and cough, as well as determine any correspondences between the type and/or location of adventitious lung sounds and the type of pulmonary conditions as reported by clinicians.

Clinical Surveillance vs. Anticoagulation for Low-risk Patients With Isolated Subsegmental Pulmonary Embolism

The clinical significance of pulmonary embolism (PE) limited to the subsegmental pulmonary arteries, so called isolated subsegmental pulmonary embolism (SSPE), remains controversial. Whether isolated SSPE represents "true" PE, a clinically more benign form of PE, a physiologic lung clearing process, or a false positive result (artifact) is currently unclear and hence, whether patients with isolated SSPE benefit from anticoagulant treatment is uncertain. Despite growing evidence from observational studies that withholding anticoagulation may be a safe option in selected patients with isolated SSPE (i.e., those without concomitant deep vein thrombosis, cancer, etc.), most patients with isolated SSPE receive anticoagulant treatment, which is associated with an increased risk of bleeding. The overall objective of the randomized controlled SAFE-SSPE trial is to evaluate the efficacy and safety of clinical surveillance without anticoagulation compared to anticoagulation treatment in low-risk patients with isolated SSPE.

Trikafta Exercise Study in Cystic Fibrosis

Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent drug treatment option known as Trikafta, which contains elexacaftor, tezacaftor, and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Trikafta on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option.

Study of Treatment With Sacituzumab and Zimberelimab for Patients With Lung Cancer Confined to the Chest and Previously Operated on Who Were Not Disease-free.

Open-label, phase III, randomized, stratified (PDL1- vs PDL1+), 3 arms, multicenter clinical trial. 129 resected patients (43 per arm) with stage from IB to IIIA and IIIB (N2) non-small cell lung cancer that do not achieve pathologic complete response (pCR) after neoadjuvant treatment. This clinical trial has 3 arms of treatment. ARM 1: Observation 10 months, ARM 2: treatment with immunotherapy (Zimberelimab) for 13 cycles and ARM 3: treatment with Sacituzumab Govitecan and Zimberelimab for 8 cycles and Zimberelimab monotherapy for 5 cycles. The primary objective is to evaluate the disease-free survival (DFS): defined as the length of time from randomization to the earliest event defined as disease recurrence, any new lung cancer (even in the opposite lung), or death from any cause at any known point in time. Patient accrual is expected to be completed within 2 years, treatment is planned to extend during 1 years and the patients will be followed up for 2 years. The study will end once survival follow-up has concluded.

CF Bronchodilation

It is estimated that one in every 3,600 children in Canada has cystic fibrosis (CF). CF is a genetic disease that affects the glands that produce mucus and sweat. In CF, mucus production increases and the mucus becomes thick and sticky. This can block the airways, making it difficult to breathe. Mucus production also causes bacteria to grow, which can lead to infections in the lungs. Individuals with CF suffer from shortness of breath, wheezing, cough, and poor exercise capacity. There are limited treatment options to reduce shortness of breath in these individuals. Some medications known as bronchodilators are commonly prescribed to reduce breathlessness in patients with CF. These drugs help open the airways making it easier to breathe. Unfortunately, there is limited scientific proof that these drugs can reduce shortness of breath and improve exercise capacity in patients with CF. As a result, some experts have recommended that these drugs should not be prescribed for patients with CF. The purpose of this study is to examine the effects of a bronchodilator on shortness of breath, exercise performance, and breathing responses compared to a placebo drug in adults with CF.

Revised-Paravertebral Nerve Blocks for Enhanced Recovery After Video-assisted Thoracoscopic Pneumonectomy

Revised-Paravertebral Nerve Block (r-PVB) is performed right after induction of general anesthesia and before lateral positioning of surgery. Under ultrasound guidance, an intercostal space between the 6th and 8th ribs at the midaxillary line is identified. Using an in-plane technique, the needle is advanced into the internal intercostal muscle, and 30 mL of 0.5% ropivacaine is injected to achieve the block. Traditional Paravertebral Nerve Block (PVB) is performed right after the lateral positioning of surgery under ultrasound guidance. According to the operator's preference, choose any of the commonly used three traditional paravertebral block approaches. Among these 3 approaches, the axial plane approach is recommended as the first choice: use the convex probe to identify the 6th and 8th transverse processes, then scan cranially to display the superior costotransverse ligament, pleura, and paravertebral space. Under sterile conditions, insert the needle in-plane approximately 2 cm lateral to the probe, ensuring the ultrasound probe remains stable and dynamically visualizing the needle advancement. Stop advancing the needle when the tip passes through the superior costotransverse ligament. Administer 2% lidocaine in pulsatile injections, 1-2 ml per pulse, observing the spread of fluid at the needle tip on ultrasound and depression of the pleura. Repeat pulsatile injections until a total of 5 ml lidocaine is administered, and if necessary, increase with another 5 ml of pulsatile lidocaine. The fluid movement and pleura depression observed on ultrasound confirm proper needle placement. Then, use this needle to inject 30 ml of 0.5% ropivacaine to complete the PVB. The surgical procedure will start right after the intervention blocks.

A Study of How Ibuzatrelvir is Taken up Into the Blood of Healthy Adults After Taking Different Tablets of Ibuzatrelvir

Healthy adults will be enrolled into this open-label, Phase 1 research study. Participants will spend about 9 nights and 10 days in the clinical research unit (CRU) and the total time in the study will be about 11 weeks.

Lung Cancer Screening CT for Firefighters

Firefighters are at increased risk for cancer due to exposure to carcinogenic substances. Current lung cancer screening guidelines are predominantly based on smoking history and do not take into account high risk occupational exposures such as firefighting. This study aims to provide chest computed tomography (CT) scans to firefighters to determine the prevalence of lung cancer, other cancers detectable on CT chest, and lung diseases associated with increased cancer risk.

Respiratory Muscles and Work of Breathing in Children

Respiratory muscle testing allows a quantitative assessment of inspiratory and expiratory muscles in children of any age with primary or secondary respiratory muscle impairment, in order to better understand the pathophysiology of respiratory impairment and guide therapeutic management. The use of an invasive technique (esogastric probe) makes it possible to specifically explore the diaphragm, the accessory inspiratory muscles and the expiratory muscles in order to detect dysfunction or paralysis of these muscles, and to estimate the work of breathing in order to better guide the respiratory management. The primary objective of the study is to evaluate the respiratory effort in children with primary or secondary impairment of the respiratory muscles during spontaneous breathing or during mechanical ventilation.

Comparison of Two Strategies of One-lung Ventilation in Patients Undergoing Carcinological Lung Resection Surgery.

During thoracic surgery, one-lung ventilation (OLV) is associated with hypoxemia, lung injury, and perioperative respiratory complications. The level of positive-end expiratory pressure (PEEP) to apply during OLV remains controversial. The open-lung approach consists in setting a level of PEEP corresponding to the best lung compliance, using an esophageal catheter to measure the transpulmonary pressure. This approach has been effective in laparoscopic surgeries or acute respiratory distress syndrome, but has never been evaluated in thoracic surgery.
