Cost-effectiveness of follow-up algorithms for chronic thromboembolic pulmonary hypertension in pulmonary embolism survivors.

Introduction: Achieving an early diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) in pulmonary embolism (PE) survivors results in better quality of life and survival. Importantly, dedicated follow-up strategies to achieve an earlier CTEPH diagnosis involve costs that were not explicitly incorporated in the models assessing their cost-effectiveness. We performed an economic evaluation of 11 distinct PE follow-up algorithms to determine which should be preferred.

Pharmacotherapy from Pre-COVID to Post-COVID: Longitudinal Trends and Predictive Indicators for Long COVID Symptoms.

Background/objectives: A significant number of COVID-19 cases experience persistent symptoms after the acute infection phase, a condition known as long COVID or post-acute sequelae of COVID-19. Approved prevention and treatment options for long COVID are currently lacking. Given the heterogeneous nature of long COVID, a personalized medicine approach is essential for effective disease management.

Deep phenotyping of pulmonary edema and pulmonary vascular permeability in COVID-19 ARDS.

Clinical monitoring of pulmonary edema due to vascular hyperpermeability in acute respiratory distress syndrome (ARDS) poses significant clinical challenges. Presently, no biological or radiological markers are available for quantifying pulmonary edema. Our aim was to phenotype pulmonary edema and pulmonary vascular permeability in patients with coronavirus disease 2019 (COVID-19) ARDS.

Role of Forkhead box F1 in the Pathobiology of Pulmonary Arterial Hypertension.

Rationale: Approximately 80% of patients with non-familial pulmonary arterial hypertension (PAH) lack identifiable pathogenic genetic variants. While most genetic studies of PAH have focused on predicted loss-of-function variants, recent approaches have identified ultra-rare missense variants associated with the disease. encodes a highly conserved transcription factor, essential for angiogenesis and vasculogenesis in human and mouse lungs.

Numbering up and sizing up gliding arc reactors to enhance the plasma-based synthesis of NO .

Non-thermal plasma-based NO synthesis from ambient air is receiving an increasing amount of interest for its potential in small-scale, sustainable fertilizer production. Nevertheless, most reported research focuses on lab-scale systems and a single reactor with limited production. In this work, two gliding arc reactors (GARs) with 2 mm discharge gaps were connected in series or in parallel to explore strategies for scaling up the productivity.

Emerging multimodality imaging techniques for the pulmonary circulation.

Pulmonary hypertension (PH) remains a challenging condition to diagnose, classify and treat. Current approaches to the assessment of PH include echocardiography, ventilation/perfusion scintigraphy, cross-sectional imaging using computed tomography and magnetic resonance imaging, and right heart catheterisation. However, these approaches only provide an indirect readout of the primary pathology of the disease: abnormal vascular remodelling in the pulmonary circulation.

Patient- vs Physician-Initiated Response to Symptom Monitoring and Health-Related Quality of Life: The SYMPRO-Lung Cluster Randomized Trial.

Importance: Online symptom monitoring through patient-reported outcomes can enhance health-related quality of life and survival. However, widespread adoption in clinical care remains limited due to various barriers including the need to reduce health care practitioners' workload.

Objective: To report the effects of patient-reported outcome (PRO) symptom monitoring on HRQOL and survival up to 1 year after initiation of any treatment in patients with lung cancer.

Low nailfold capillary density in patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension: biomarker of clinical outcome?

Nailfold capillary density is lower in patients with pulmonary arterial hypertension (PAH). It is unclear whether this observation signifies a unique systemic manifestation of PAH, or reflects microcirculatory dysfunction secondary to pulmonary hypertension (PH). Capillary density and loop dimensions were measured by nailfold-capillaroscopy (NC) in 30 PAH (23 idiopathic, or iPAH, 7 hereditary, or hPAH), 17 chronic thromboembolic PH (CTEPH) patients and 48 controls.

Role of Exercise Hemodynamics in the Prediction of Pulmonary Arterial Hypertension in BMPR2 Mutation Carriers.

Background: Exercise hemodynamics are recommended for early detection of pulmonary arterial hypertension (PAH) and have been suggested to be predictive of future development of PAH in high-risk populations such as BMPR2 mutation carriers. However, the optimal exercise hemodynamic screening parameter remains to be determined. Recent data suggest that pulmonary vascular distensibility (α) may serve as a useful parameter for early detection of PAH.

Optimisation of detecting chronic thromboembolic pulmonary hypertension in acute pulmonary embolism survivors: the InShape IV study.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is often diagnosed late in acute pulmonary embolism survivors: more efficient testing to expedite diagnosis may considerably improve patient outcomes. The InShape II algorithm safely rules out CTEPH (failure rate 0.29%) while requiring echocardiography in only 19% of patients but may be improved by adding detailed reading of the computed tomography pulmonary angiography diagnosing the index pulmonary embolism.

Evaluating the technical use of a Fitbit during an intervention for patients with pulmonary arterial hypertension with quality of life as primary endpoint: Lessons learned from the UPHILL study.

This article examines technical use of Fitbit during an intervention for pulmonary hypertension (PAH)-patients. Technical issues with the device led to data being unavailable(37.5%).

Notch ratio in pulmonary flow predicts long-term survival after pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension.

Background: Assessment of the pattern of the RV outflow tract Doppler provides insights into the hemodynamics of chronic thromboembolic pulmonary hypertension (CTEPH). We studied whether pre-operative assessment of timing of the pulmonary flow systolic notch by Doppler echocardiography is associated with long-term survival after pulmonary endarterectomy (PEA) for CTEPH.

Methods: Fifty-nine out of 61 consecutive CETPH patients (mean age 53 ± 14 years, 34% male) whom underwent PEA between June 2002 and June 2005 were studied.

Predominance of M2 macrophages in organized thrombi in chronic thromboembolic pulmonary hypertension patients.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a debilitating disease characterized by thrombotic occlusion of pulmonary arteries and vasculopathy, leading to increased pulmonary vascular resistance and progressive right-sided heart failure. Thrombotic lesions in CTEPH contain CD68 macrophages, and increasing evidence supports their role in disease pathogenesis. Macrophages are classically divided into pro-inflammatory M1 macrophages and anti-inflammatory M2 macrophages, which are involved in wound healing and tissue repair.

Tricuspid regurgitation in pulmonary arterial hypertension: a right ventricular volumetric and functional analysis.

Background: The consequences of tricuspid regurgitation (TR) for right ventricular (RV) function and prognosis in pulmonary arterial hypertension (PAH) are poorly described and effects of tricuspid valve repair on the RV are difficult to predict.

Methods: In 92 PAH patients with available cardiac magnetic resonance (CMR) studies, TR volume was calculated as the difference between RV stroke volume and forward stroke volume, pulmonary artery (PA) stroke volume. Survival was estimated from the time of the CMR scan to cardiopulmonary death or lung transplantation.

Pulmonary vascular phenotype identified in patients with () or variants: an international multicentre study.

Background: Bone morphogenetic proteins 9 and 10 (BMP9 and BMP10), encoded by and , respectively, play a pivotal role in pulmonary vascular regulation. variants have been reported in pulmonary arterial hypertension (PAH) and hereditary haemorrhagic telangiectasia (HHT). However, the phenotype of and carriers remains largely unexplored.
