Sternal Elevation by Crane Technique During Double Lung Transplant for Patient With Pectus Excavatum.

We present the case of a 28-year-old female patient who underwent a bilateral lung transplantation for underlying terminal bronchopulmonary dysplasia. The peroperative access to the hilum of the right lung was significantly compromised due to the presence of a pectus excavatum (Haller index 11). We used a wired sternal crane technique to elevate the sternum and gain exposure.

Airway Remodeling in Cystic Fibrosis Is Heterogeneous.

RATIONALE+OBJECTIVE/ Cystic fibrosis (CF) is characterized by bronchiectasis on imaging, while functionally evolving towards obstructive impairment. Despite its assumed importance in CF, small airway remodeling and its relation to bronchiectasis, is still poorly understood. METHOD/ On high-resolution computed tomography (HRCT, 600µm, CF=21, control=6) and micro-computed tomography (µCT, 150µm, CF=3, control=1) scans of inflated explant lungs, AV% (airway/total lung volume) was calculated as marker for bronchiectasis, while airway segmentation was used for generation analysis.

Predicting lung aging using scRNA-Seq data.

Age prediction based on single cell RNA-Sequencing data (scRNA-Seq) can provide information for patients' susceptibility to various diseases and conditions. In addition, such analysis can be used to identify aging related genes and pathways. To enable age prediction based on scRNA-Seq data, we developed PolyEN, a new regression model which learns continuous representation for expression over time.

Lung volume reduction: surgery endobronchial valves.

Volume reduction is a disease-modifying treatment that aims to reshape the diseased lung towards a more normal total lung capacity by removing severely damaged and overinflated lung parenchyma. It is an effective therapeutic strategy in well-selected patients, resulting in improvements in exercise tolerance, lung function, quality of life and survival. The most widespread strategies for volume reduction are either video-assisted thoracoscopic surgery or bronchoscopic lung volume reduction.

Heterogeneous neutrophils in lung transplantation and proteolytic CXCL8 activation in COVID-19, influenza and lung transplant patient lungs.

Elevated neutrophil counts in broncho-alveolar lavage (BAL) fluids of lung transplant (LTx) patients with chronic lung allograft dysfunction (CLAD) are associated with disease pathology. However, phenotypical characteristics of these cells remained largely unknown. Moreover, despite enhanced levels of the most potent human neutrophil-attracting chemokine CXCL8 in BAL fluid, no discrimination had been made between natural NH-terminally truncated CXCL8 proteoforms, which exhibit up to 30-fold differences in biological activity.

Donor-Specific Blood Transfusion in Lung Transplantation.

Lung transplantation is still hindered by a high rate of chronic rejection necessitating profound immunosuppression with its associated complications. Donor-specific blood transfusion is a pre-transplant strategy aimed at improving graft acceptance. In contrast with standard stored blood or donor-specific regulatory T cells transfusions, this approach utilizes fresh whole blood from the donor prior to allograft transplantation, encompassing all cell types and plasma.

Risk factors for SARS-CoV-2 infection and severe COVID-19 in unvaccinated solid organ transplant recipients.

The role of immunosuppressive therapy on SARS-CoV-2 infection risk and COVID-19 severity remains unclear in unvaccinated solid organ transplant recipients. We included 1957 organ transplant recipients between July 2020 and April 2021 to analyze whether baseline immunosuppressive therapy and other risk factors are associated with SARS-CoV-2 infection and severe COVID-19. In total, 247 (12.

The effect of rewarming ischemia on tissue transcriptome and metabolome signatures: A clinical observational study in lung transplantation.

Background: In lung transplantation (LuTx), various ischemic phases exist, yet the rewarming ischemia time (RIT) during implantation has often been overlooked. During RIT, lungs are deflated and exposed to the body temperature in the recipient's chest cavity. Our prior clinical findings demonstrated that prolonged RIT increases the risk of primary graft dysfunction.

Allogeneic abdominal non-vascularized rectus fascia transplantation without immunosuppression equals syngeneic transplantation in a rabbit model at short-term follow-up.

Complex abdominal wall repair remains a major surgical challenge. In transplant patients, non-vascularized rectus fascia (NVRF) is successfully used to bridge the defect. To extrapolate this to non-transplant patients, we developed a rabbit model of NVRF-transplantation without immunosuppression comparing syngeneic versus allogeneic transplants.

Extended Lichtenstein Repair for an Additional Femoral Canal Hernia.

The Lichtenstein procedure is one of the most performed surgeries worldwide. However, proper examination to exclude a femoral hernia is often not performed, resulting in a high number of missed hernias. For patients in whom a femoral hernia is suspected pre- or intraoperatively, we describe a novel surgical technique of a femoral extension to the classic Lichtenstein repair.

Pericardial fenestration and thoracic duct ligation for treatment of chylopericardium as first symptom of underlying generalized lymphatic anomaly: a case report.

Introduction: Chylopericardium represents a rare condition of chyle accumulation within the pericardial sac, caused by abnormal thoracic duct anatomy or prolonged increased pressure. Nothing by mouth (NPO) policy and total parenteral nutrition (TPN), even in combination with pericardial drainage, render only a temporary solution. Surgical intervention with thoracic duct ligation and creation of a pericardial window is believed to be the most effective treatment.

Comparing right- versus left-first implantation in off-pump sequential double-lung transplantation: an observational cohort study.

Objectives: Historically, the perfusion-guided sequence suggests to first transplant the side with lowest lung perfusion. This sequence is thought to limit right ventricular afterload and prevent acute heart failure after first pneumonectomy. As a paradigm shift, we adopted the right-first implantation sequence, irrespective of lung perfusion.

Lung transplantation following controlled hypothermic storage with a portable lung preservation device: first multicenter European experience.

Introduction: Compared with traditional static ice storage, controlled hypothermic storage (CHS) at 4-10°C may attenuate cold-induced lung injury between procurement and implantation. In this study, we describe the first European lung transplant (LTx) experience with a portable CHS device.

Methods: A prospective observational study was conducted of all consecutively performed LTx following CHS (11 November 2022 and 31 January 2024) at two European high-volume centers.
