RSV-specific anti-viral immunity is disrupted by chronic ethanol consumption
Alcohol-use disorders (AUD) persist in the United States and are heavily associated with an increased susceptibility to respiratory viral infections. Respiratory syncytial virus (RSV) in particular has received attention as a viral pathogen commonly detected in children and immune-compromised populations (elderly, asthmatics), yet more recently was recognized as an important viral pathogen in young adults. Our study evaluated the exacerbation of RSV-associated illness in mice that chronically consumed alcohol for 6 weeks prior to infection. (Source: Alcohol)

Investigating asthma comorbidities: a systematic scoping review protocol
Introduction Asthma is a common long-term disorder with a number of related comorbid conditions, which may affect asthma outcomes. There is a need for greater appreciation for understanding how these comorbidities interact with asthma in order to improve asthma outcomes. Objectives To systematically identify and map out key asthma comorbidities. Methods We will systematically search the following electronic databases: MEDLINE, EMBASE, ISI Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and Google Scholar. Additional literature will be identified by searching the reference list ...

Intrauterine growth restriction impairs right ventricular response to hypoxia in adult male rats.
CONCLUSIONS: In adult IUGR-born rats, mitochondria from RV are hypersensitive to oxygen deprivation and this translates into maladaptive RV cardiac response to acute hypoxia.Pediatric Research (2016); doi:10.1038/pr.2016.124.

Systems Biology and Clinical Practice in Respiratory Medicine: The Twain Shall Meet.
We describe new studies using temporal complexity patterns to characterize asthma and COPD and predict exacerbations, as well as predict adverse outcomes in critical care. We highlight new methods which are emerging with this approach, and discuss remaining questions which merit greater attention in the field.

RTP801 Amplifies Nox-4-dependent Oxidative Stress Induced by Cigarette Smoke.
Abstract Tobacco smoke (TS) causes chronic obstructive pulmonary disease including, chronic bronchitis, emphysema and asthma. Rtp801, an inhibitor of mTORC1, is induced by oxidative stress triggered by TS. Its upregulation drives lung susceptibility to TS injury by means of enhancing inflammation and alveolar destruction. We postulated that Rtp801 is not only increased by reactive oxygen species (ROS) in TS, but it is instrumental in creating a feedforward process leading to amplification of endogenous ROS generation. We used cigarette smoke extract (CSE) to model the effect of TS in wild type (Wt) and knockout (K...

An Inhaled Inhibitor of MARCKS Reverses LPS-induced Acute Lung Injury in Mice.
Abstract Intratracheal (IT) instillation of bacterial lipopolysaccharide (LPS) is a well-established model of acute lung injury (ALI) and/or acute respiratory distress syndrome (ARDS). Since the myristoylated alanine-rich C Kinase substrate (MARCKS) protein is involved in neutrophil migration and proinflammatory cytokine production, we examined whether an aerosolized peptide that inhibits MARCKS function could attenuate LPS - induced lung injury in mice. The peptide, BIO-11006, was delivered at 50 μM via inhalation either just prior to IT instillation of 5μg of LPS into Balb/C mice, or 4, 12, 24 or 36 hrs after ...

A brief clinical case of monitoring of oxygenator performance and patient-machine interdependency during prolonged veno-venous extracorporeal membrane oxygenation
AbstractMonitoring veno-venous extracorporeal membrane oxygenation (vvECMO) during 76 days of continuous support in a 42-years old patient with end-stage pulmonary disease, listed for double-lung transplantation. Applying a new monitor (Landing®, Eurosets, Medolla, Italy) and describing how measured and calculated parameters can be used to understand the variable interdependency between artificial membrane lung (ML) and patient native lung (NL). During vvECMO, in order to understand how the respiratory function is shared between ML and NL, ideally we should obtain data about oxygen transfer and CO2 removal, both by ML a...

From Genesis To Revelation: The Role Of Inflammatory Mediators In Chronic Respiratory Diseases And Their Control By Nucleic Acid-Based Drugs.
Abstract Asthma, chronic obstructive pulmonary disease, cystic fibrosis, and idiopathic pulmonary fibrosis, are among the most common chronic diseases and their prevalence is increasing. Each of these diseases is characterized by the secretion of cytokines and pro-inflammatory molecules which are thought to play a critical role in their pathogenesis. Moreover, immune cells, particularly neutrophils, macrophages and dendritic cells as well structural cells such as epithelial and airway smooth muscle cells are also involved in the pathogenic cycle of these diseases. There is a pressing need for the development of ne...

Impaired utilization of membrane potential by complex II-energized mitochondria of obese, diabetic mice assessed using ADP recycling methodology.
Abstract Recently, we used an ADP recycling approach to examine mouse skeletal muscle (SkM) mitochondrial function over respiratory states intermittent between state 3 and 4. We showed that respiration energized at complex II by succinate, in the presence of rotenone to block complex I, progressively increased with incremental additions of ADP. However, in the absence of rotenone, respiration peaked at low [ADP] but then dropped markedly as [ADP] was further increased. Here, we tested the hypothesis that these respiratory dynamics would differ between mitochondria of mice fed high-fat (HF) and treated with a low d...

Obesity is Associated with Increased Morbidity in Moderate to Severe COPD.
CONCLUSIONS: Obesity is prevalent among individuals with COPD and associated with worse COPD-related outcomes, ranging from QOL and dyspnea to 6MWD and severe AECOPD. These associations were strengthened when obesity was analyzed as a dose-dependent response. Obesity in patients with COPD may contribute to a worse COPD-related course.

Nivolumab-Induced Pericardial Tamponade: A Case Report and Discussion
We present the case of a 67-year-old male patient with metastatic squamous cell carcinoma of the lung who suffered from a massive pericardial effusion secondary to treatment with nivolumab, which he began in June 2015. After five cycles the patient was hospitalized due to acute respiratory failure requiring mechanical ventilation. An echocardiogram revealed a massive pericardial effusion with tamponade. After pericardiocentesis and corticosteroid treatment, the patient's condition improved rapidly. A CT scan revealed a response of the tumor. Although anti-PD1 treatment is usually regarded as less toxic than chemotherapy, a...

Telehealthcare for Chronic Obstructive Pulmonary Disease in Switzerland Is Feasible and Appreciated by Patients
Conclusions: Adding THC to state-of-the-art COPD management is feasible in a selected subgroup of patients. We estimate that up to 50% of COPD patients could be eligible for a THC strategy. Patient compliance, acceptance and satisfaction were very high. With the proposed approach, we missed only very few AECOPD events. However, a telephone-based verification of THC alerts was required. Overall, in this proof-of-concept study, we experienced a positive effort-to-benefit ratio.Respiration (Source: Respiration)

Infection in Early Life and Risk of Developing Type 1 Diabetes
In Reply Dr Rahmoune and colleagues and Mr Uzoigwe suggest that unmeasured confounding might have influenced the results of our study. The results are consistent with findings from a previous analysis that observed a strong association between respiratory infections during the first 6 months of life and development of beta cell autoimmunity in infants with a family history of T1D. This association was independent of early variables such as delivery mode, age at gluten introduction, season of birth, and antibiotic use in children, and could not be explained by modulations of the gut microbiome, suggesting that such confound...

Respiratory pattern in a FSHD pediatric population
Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant inherited disorder characterized by selective weakness of face and upper arms and girdle. Respiratory involvement in FSHD has been described mainly in the most severely affected patients. In this work we tested the respiratory function by spirometry in 12 patients affected by FSHD with onset before 18 years. Spirometry results were correlated with motor involvement and compared to aged matched group of Becker patients. Of note FSHD patients present a peculiar pattern characterized by a flat shape in flow-volume loop. (Source: Respiratory Medicine)
