Amyotrophic lateral sclerosis (ALS) is the most prevalent neuromuscular disease worldwide. It is a lethal and progressive neurodegenerative disease, principally affecting motor neurons; patient clinical characteristics are muscle weakness, dysphagia and respiratory failure. The mean age is related to family history (40years, familial ALS or FALS) or with no family history (50years), but it is more common in people aged 60-69years. The cause of ALS is not known and it is not known yet why it affects some people and not others...

Recent studies show improved outcomes in ambulated lung failure patients. Ambulation still remains a challenge in these patients. This necessitates development of more compact and less cumbersome respiratory support specifically designed to be wearable. The Paracorporeal Ambulatory Assist Lung (PAAL) is being designed for providing ambulatory support in lung failure patients during bridge to transplant or recovery. We previously published in vitro and acute in vivo results of the PAAL. This study further evaluates the PAAL for 5 days...

Acute and chronic respiratory failure are a significant source of pediatric morbidity and mortality. Current respiratory support options used to bridge children to lung recovery or transplantation typically render them bedridden and can worsen long-term patient outcomes. The Pittsburgh Pediatric Ambulatory Lung (P-PAL) is a wearable pediatric blood pump and oxygenator (0.3 m surface area) integrated into a single compact unit that enables patient ambulation. The P-PAL is intended for long-term use and designed to provide up to 90% of respiratory support in children weighing 5-25 kg...

BACKGROUND: Hyaluronic acid (HA), an extracellular matrix component, is degraded in response to local tissue injury or stress. In various animal models of lung injury, HA has been shown to play a mechanistic role in modulating inflammation and injury. While HA is present in the lungs of patients with acute respiratory distress syndrome (ARDS), its relationship to patient outcomes is unknown. METHODS: We studied 86 patients with ARDS previously enrolled in the Phase II Randomized Trial of Fish Oil in Patients with Acute Lung Injury (NCT00351533) at five North American medical centers...

Pseudomesotheliomatous carcinoma is a malignant tumor that extends along the pleura mimicking malignant mesothelioma. An 81-year-old male patient presented to our hospital with epigastralgia, and abdominal computed tomography (CT) showed a 36-mm tumor in the pancreatic tail. The laboratory data revealed a high leukocyte count (>44 000/μL). Chest CT showed left pleural thickening with pleural effusion. The cancer showed a poor response to chemotherapy, and the patient died of respiratory failure at 5 months after the onset of disease...

Acetaminophen (APAP) is the active component of many medications used to treat pain and fever worldwide. Its overuse provokes liver injury and it is the second most common cause of liver failure. Mitochondrial dysfunction contributes to APAP-induced liver injury but the mechanism by which APAP causes hepatocyte toxicity is not completely understood. Therefore, we lack efficient therapeutic strategies to treat this pathology. Here we show that APAP interferes with the formation of mitochondrial respiratory supercomplexes via the mitochondrial negative regulator MCJ, and leads to decreased production of ATP and increased generation of ROS...

Cellular bioenergetic failure caused by mitochondrial dysfunction is a key process of alveolar epithelial injury during acute respiratory distress syndrome (ARDS). Prolyl hydroxylases (PHDs) act as cellular oxygen sensors, and their inhibition activates hypoxia-inducible factor (HIF), resulting in enhanced cellular glycolytic activity, which could compensate for impaired mitochondrial function and protect alveolar epithelial cells from ARDS. Here, we evaluated the effects of pharmacological PHD inhibition with dimethyloxalylglycine (DMOG) on alveolar epithelial cell injury using in vitro and in vivo ARDS models...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a life-saving therapy in acute respiratory distress syndrome (ARDS) patients but is associated with complications and costs. Here, we validate various scores supposed to predict mortality and develop an optimized categorical model. METHODS: In a derivation cohort, 108 ARDS patients (2010-2015) on veno-venous ECMO were retrospectively analysed to assess four established risk scores (ECMOnet-Score, RESP-Score, PRESERVE-Score, Roch-Score) for mortality prediction (receiver operating characteristic analysis) and to identify by multivariable logistic regression analysis independent variables for mortality to yield the new PRESET-Score (PREdiction of Survival on ECMO Therapy-Score)...

BACKGROUND: Parkinson's disease (PD), a neurodegenerative disorder characterized by loss of dopaminergic neurons in the substantia nigra of the midbrain is commonly thought of as a motion disorder, but it can have significant effect on the respiratory system. Respiratory failure is the most common cause of death in these patients, but it can also affect laryngeal function causing dysphonia, dysphagia, and dysarthric speech.. Acute upper airway obstruction is a very rare finding in PD, especially in the perioperative settings...
