Ayodeji Adegunsoye, Mary E Strek, Edward Garrity, Robert Guzy, Remzi Bag
Lung transplantation has evolved into a life-saving treatment with improved quality of life for patients with end-stage respiratory failure unresponsive to other medical or surgical interventions. With improving survival rates, the number of lung transplant recipients with pre-existing and post-transplant comorbidities that require attention continues to increase. A partnership between transplant and non-transplant care providers is necessary to deliver comprehensive and optimal care for transplant candidates and recipients...

Cystic fibrosis (CF) patients are at risk for life-threatening hemoptysis, sometimes necessitating bronchial arterial embolization (BAE). Spinal artery embolization and pulmonary infarction are commonly cited procedural risks, yet respiratory failure and death are underappreciated. We conducted a retrospective institutional review of our outcomes after BAE for hemoptysis in CF and present three cases highlighting this complication. From 2007 to 2015, 12 patients underwent 17 BAE procedures for hemoptysis at our institution...

Lung transplantation is getting to be a common treatment for the end-stage respiratory failure. Therefore we might encounter the various issues associated with infection under immunosuppression. At 1st, virus infections occur by Cytomegalovirus, Epstein-Barr virus, hepatitis B and C virus and John Cunningham virus. The 2nd, bacterial infections exacerbate graft condition by methicillin-resistant Staphylococcus aureus, Pseudomonas, Burkholderia cepacia and coagulase negative staphylococci. The 3rd, fungal infections are induced by Aspergillus, Candida and Cryptococcus...

The risk of infection in advanced chronic kidney disease (CKD) and its subsequent impact on adverse outcomes are not well established. Therefore, we determined the association of an infectious episode with the subsequent risk of cardiovascular ischemia, congestive heart failure, end-stage kidney disease or mortality in a Canadian prospective cohort (CanPREDDICT) of patients with advanced CKD (eGFR: 15-45 ml/min/1.73m(2)) followed by nephrologists for up to 5 years. Infectious episodes were classified by anatomic location and identified by positive culture, hospital admission, or use of antibiotics...

PURPOSE: Vascular calcification (VC) is an impact of calcium accumulation in end-stage renal diseases, normally initiated in the mitochondria. Sodium thiosulfate (STS) is effective in rescuing mitochondrial function in the neurovascular complications associated with VC, but has limitation in protecting the cardiac mitochondria. However, the STS efficacy in restoring the renal mitochondrial function has not been studied, which is the primary focus of this study. METHODS: Wistar rats (n = 6/group) were administered 0...

BACKGROUND: Lung transplantation is considered an established treatment for patients with end-stage chronic respiratory failure. Patients with acute respiratory failure requiring respiratory support with invasive mechanical ventilation while awaiting lung transplantation are at high risk of death. Extracorporeal membrane oxygenation (ECMO) has been proposed as an alternative bridging strategy to mechanical ventilation. The shear stress created by the mechanical pumps causes changes in the hematological system in almost all patients treated with ECMO...

Pulmonary fibrosis (PF) constitutes the end stage of a broad range of heterogeneous interstitial lung diseases, characterized by the destruction of the pulmonary parenchyma, deposition of extracellular matrix and dramatic changes in the phenotype of both fibroblasts and alveolar epithelial cells. More than 200 causes of pulmonary fibrosis have been identified so far, yet the most common form is idiopathic pulmonary fibrosis (IPF). IPF is a lethal lung disorder of unknown etiology with a gradually increasing worldwide incidence and a median survival of 3-5 years from the time of diagnosis...

Life threatening event due to central airway obstruction caused by very large blood clot formation with profuse on going bleeding its very challenging to manage. Interventional pulmonologist must aware about this situation which can lead to respiratory failure. There are several choices to treat this unlikely situation, in example flexible bronchoscopy with forceps, bronchial lavage, and suction. We present a case with post-surgical tracheostomy bleeding which caused a giant blood clot formation in a disseminated intravascular coagulation due to severe sepsis in end stage renal disease patient, successfully managed with cryoextraction and argon plasma coagulation...

INTRODUCTION: The administration of medication by inhalation has become the most important route in treating airway diseases. The efficacy of this route depends on several factors like correct inhalation techniques, compliance and the size of the particles. The flow properties and internal flow distribution contribute to the deposition pattern. AREAS COVERED: What has been less well studied is the effect of the internal flow distribution. We know from recent studies that using systemic anti-inflammatory compounds that open up the distal airways redistributes flow internally and enhances the deposition of inhaled particles to the active site of bronchoconstriction or airway inflammation...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is an effective therapy for patients with reversible cardiac and/or respiratory failure. Acute kidney injury (AKI) often occurs in patients supported with ECMO; it frequently evolves into chronic kidney damage or end-stage renal disease and is associated with a reported 4-fold increase in mortality rate. Although AKI is generally due to the hemodynamic alterations associated with the baseline disease, ECMO itself may contribute to maintaining kidney dysfunction through several mechanisms...

During human heart failure, the balance of cardiac energy use switches from predominantly fatty acids (FAs) to glucose. We hypothesized that this substrate shift was the result of mitochondrial degeneration; therefore, we examined mitochondrial oxidation and ultrastructure in the failing human heart by using respirometry, transmission electron microscopy, and gene expression studies of demographically matched donor and failing human heart left ventricular (LV) tissues. Surprisingly, respiratory capacities for failing LV isolated mitochondria (n = 9) were not significantly diminished compared with donor LV isolated mitochondria (n = 7) for glycolysis (pyruvate + malate)- or FA (palmitoylcarnitine)-derived substrates, and mitochondrial densities, assessed via citrate synthase activity, were consistent between groups...

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a treatment option to correct blood oxygenation in cases of severe respiratory failure. However, it is time-limited and, in cases of no- recovery, it is a bridge-to-lung transplant therapy. We report our experience of two patients waiting for emergency lung transplantation under VV-ECMO using the Avalon® cannula. Both presented signs of ECMO failure after prolonged support, i.e. increased hemolysis, decreased blood flow rate and increased negative pressure of the venous inflow line, leading to an inadequate systemic oxygenation...
