The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years...

Acute respiratory distress syndrome (ARDS) is characterized by inflammatory injury to the alveolar and capillary barriers that results in impaired gas exchange and severe acute respiratory failure. Nuclear orphan receptor Nur77 has emerged as a regulator of gene expression in inflammation and its role in the pathogenesis of ARDS is not clear. The objective of this study is to investigate the potential role of Nur77 and its underlying mechanism in the regulation of endothelin-1 (ET-1) expression in LPS-induced A549 cells and an ARDS rat model...

Little is known about the host factor in the response to PRRSV vaccination. For this purpose, piglets were immunized with a commercial PRRSV-live vaccine and classified as high responders (HR) or low responders (LR) as regards to the frequencies of virus-specific IFN-γ-secreting cells. Six weeks post vaccination, PBMCs isolated from three individuals with the most extreme responses in each HR and LR groups and 3 unvaccinated controls, were either stimulated with phytohaemagglutinin, challenged with the vaccine or mock treated for 24 h, prior conducting transcriptional studies, gene ontology and pathway analyses...

Pompe disease is an autosomal-recessive lysosomal storage disorder characterized by progressive myopathy with proximal muscle weakness, respiratory muscle dysfunction, and cardiomyopathy (in infants only). In patients with juvenile or adult disease onset, respiratory muscle weakness may decline more rapidly than overall neurological disability. Sleep-disordered breathing, daytime hypercapnia, and the need for nocturnal ventilation eventually evolve in most patients. Additionally, respiratory muscle weakness leads to decreased cough and impaired airway clearance, increasing the risk of acute respiratory illness...

The taste detection system for oral fatty acid may be related to obesity. In addition, sleep is intrinsically and closely related to food intake and metabolism. However, the association of gustatory salivation with body mass index (BMI), daytime sleepiness, or sleep habits is largely unknown. Therefore, we evaluated the relationship between gustatory salivation and BMI, Epworth sleepiness scale (ESS, a daytime sleepiness scale) or sleep habits among 26 healthy young individuals (20 males and 6 females; mean age: 26...

The cyclic electron flow around photosystem I (CEF-PSI) increases ATP/NADPH production in the chloroplast acting as an energy balance mechanism. Higher export of reducing power from the chloroplast in CEF-PSI mutants has been correlated with higher mitochondrial alternative oxidase (AOX) capacity and protein amount under high light (HL) conditions. However, in vivo measurements of AOX activity are still required to confirm the exact role of AOX on dissipating the excess of reductant power from the chloroplast...

To allow breathing and prevent alveolar collapse, lung surfactant (LS) develops a complex membranous system at the respiratory surface. LS is defined by a specific protein and lipid composition, including saturated and unsaturated phospholipid species and cholesterol. Surfactant protein C (SP-C) has been suggested to be an essential element for sustaining the presence of cholesterol in surfactant without functional impairment. In this work, we used a fluorescent sterol-partitioning assay to assess the effect of the surfactant proteins SP-B and SP-C on cholesterol distribution in membranes...

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, no investigation had sought to determine if swallowing impairments were present in persons with PWS...

PURPOSE OF REVIEW: To revise the current literature on concepts for neuromuscular block management. Moreover, consequences of incomplete neuromuscular recovery on patients' postoperative pulmonary outcome are evaluated as well. RECENT FINDINGS: The incidence of residual paralysis may be as high as 70% and even small degrees of residual paralysis may have clinical consequences. Neostigmine should not be given before return of the fourth response of the train-of-four-stimulation and no more than 40-50 μg/kg should be given...

We present a patient with congenital spinal muscular atrophy associated with pain, subjective sensory loss, right talipes equinovarus, delayed walking, and progressive gait impairment. A sister and niece reportedly had Charcot-Marie-Tooth 1A, but the patient's electromyogram showed an axonal motor neuropathy or neuronopathy. We identified a c.806G>A TRPV4 gene mutation causing an Arg269His amino acid substitution. TRPV4 mutations cause variable phenotypes including axonal sensorimotor neuropathy and motor neuropathy or neuronopathy...

BACKGROUND: Seizures can lead to cardiac arrhythmias by a number of mechanisms including activation/inhibition of cortical autonomic centers, increase in vagal tone through activation of brainstem reflex centers, and respiratory failure. Ictal asystole (IA) is a potential mechanism underlying sudden unexpected death in epilepsy (SUDEP). We analyzed the clinical features of 5 patients who developed IA requiring pacemaker implantation. METHODS: Patients with ictal arrhythmias were identified from the video-telemetry and ambulatory EEG database at Greater Manchester Neurosciences Centre, as well as an independent epilepsy residential care facility...

BACKGROUND: The decision to extubate brain-injured patients with residual impaired consciousness holds a high degree of uncertainty of success. The authors developed a pragmatic clinical score predictive of extubation failure in brain-injured patients. METHODS: One hundred and forty brain-injured patients were prospectively included after the first spontaneous breathing trial success. Assessment of multiparametric hemodynamic, respiratory, and neurologic functions was performed just before extubation...

INTRODUCTION: Psoriatic arthritis (PsA) is an immune-mediated chronic inflammatory arthropathy associated with impaired physical function and reduced quality of life. Biologic therapies that target tumor necrosis factor (anti-TNF) have significantly improved clinical outcomes. Partial, non- and transient responses remain common comprising significant unmet clinical need. New therapies with novel modes of action are urgently required. OBJECTIVES: The interleukin (IL)-17 pathway has recently been attributed a critical role in the pathogenesis of spondyloarthritides...
