The ‘strike early and strike strong’ lipid-lowering strategy emphasises rapid reduction of low-density lipoprotein cholesterol (LDL-C) in patients with acute coronary syndrome (ACS). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are increasingly used alongside statins to achieve guideline-recommended LDL-C targets after ACS. However, despite substantial LDL-C reductions with early PCSK9i initiation, their effects on non-culprit coronary atherosclerotic plaques remain unclear. This study aims to assess the impact of early intensive LDL-C lowering with PCSK9i added to moderate-intensity statin therapy on optical coherence tomography (OCT)-derived plaque characteristics in non-culprit coronary lesions in patients with ACS.

In this prospective, multicentre, open-label trial, 212 patients with ACS will be randomised 1:1 to an early intensified lipid-lowering strategy (PCSK9i added to moderate-intensity statin) or guideline-directed medical therapy for 6 months. Serial OCT imaging of non-culprit coronary arteries with 20–70% stenosis will be performed at baseline and 6 months. The primary endpoint is the absolute change in minimum fibrous cap thickness within a matched target arterial segment from baseline to 6 months. Secondary endpoints include changes in minimum lumen area, maximum lipid arc, presence of macrophage infiltration, LDL-C reduction and achievement of LDL-C targets. The primary endpoint will be analysed using analysis of covariance, adjusting for treatment group, baseline LDL-C stratification (≥1.8 vs

Transitions of care (TOC) between hospital, ambulatory and home settings for high-risk adults with chronic diseases are complex, costly and often result in poor health outcomes. Suboptimal care transitions lead to medication errors, non-adherence, decreased self-management skills and inadequate follow-up, all of which contribute to readmissions or emergency department visits. The Transitional Care Model aims to address these challenges through patient-centred, in-home interventions. We propose to implement and evaluate TELE-TOC: Telehealth Education Leveraging Electronic Transitions Of Care for Chronic Obstructive Pulmonary Disease (COPD) patients. This study will evaluate the added value of a virtual, pharmacy-based intervention integrated into an existing COPD TOC program within a single healthcare system.

Informed by the Proctor Framework implementation, service and health outcome domains, we will conduct a randomised controlled trial comparing the addition of at-home pharmacy team-based virtual visits to the standard of care (ie, our existing COPD TOC programme). Adult patients hospitalised for a COPD exacerbation will be randomised to receive the standard COPD TOC programme alone or the standard programme plus TELE-TOC virtual at-home pharmacy visits. We will use a pragmatic type II hybrid effectiveness-implementation trial. The primary effectiveness outcome is inhaler technique at 30 days postdischarge, and the primary implementation outcome is the proportion of patients receiving the intervention. Intention-to-treat analysis will be applied to all outcomes with ² and logistic regression models adjusting for demographic factors. Treatment effects through 30 days will be assessed with generalised estimating equations and generalised linear mixed models.

This study, the waiver of consent and the opt-out flyer were approved by the University of Chicago Institutional Review Board (23–0934). Dissemination of the findings is planned for up to 4 years of completion of the study to local, regional and national conferences and peer-reviewed journals.

In non-intubated patients, symptomatic treatment of hypoxaemic respiratory failure is still debated, with different options: (1) standard oxygen therapy (SOT), (2) high-flow nasal cannula oxygen therapy (HFNC) and (3) non-invasive ventilation (NIV). The objective of this study is to compare the effects of HFNC and NIV on lung volumes assessed by CT scan to allow a better understanding of their effectiveness.

The HONIVAH study (High-flow Oxygen therapy and Non-Invasive ventilation on lung Volumes and on upper Airway in Hypoxemic critically ill patients) is an investigator-initiated, prospective, single-centre, physiological, randomised, parallel-group, unblinded trial with an electronic system-based randomisation. Patients with hypoxaemic respiratory failure, defined as the need for SOT flow ≥3 L/min to maintain a pulsed oxygen saturation ≥95%, and a CT scan prescribed by the physician in charge of the patient, will be randomly assigned to the HFNC group or the NIV group. Two inspiratory thoracic CT scans will be performed, one with SOT as part of the routine patient management and a second thoracic CT scan with HFNC or NIV, depending on the allocation group. The primary outcome is the comparison of the relative variation in ‘poorly aerated’ and ‘non-aerated’ lung volumes before and after the intervention between the HFNC group and NIV group, assessed by thoracic CT scan. Secondary outcomes included the variation in tracheal cross-sectional upper airway area, lung volumes, gas exchange and patient comfort.

The study project has been approved by the appropriate ethics committee (Comité de Protection des Personnes Sud-Ouest et Outre-mer 1, France, 2022-A02458-35). Informed consent is required. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.
