Therapeutic potential and mechanisms of action of Mesenchymal Stromal Cells for Acute Respiratory Distress Syndrome.
Abstract Mesenchymal stem/stromal cells (MSCs) have become the focus of intense research effort over the past 10 years, in an effort to harness their regenerative and immune-modulating capacity for a variety of clinical conditions. In Acute Respiratory Distress Syndrome (ARDS), pre-clinical studies point towards a therapy that modulates multiple aspects of a complex disease process. Almost universally, these cells have demonstrated an immune modulating phenotype, balancing protective host responses with a reduction in damaging inflammation, while enhancing bacterial killing. MSCs also lead to more efficient tissue ...

ECLS for preemies: The artificial placenta
Abstract: The high mortality and morbidity associated with respiratory failure among extremely low gestational age newborns (ELGANs) remains an unsolved problem. A logical strategy to avoid these complications would involve re-creating the intrauterine environment with extracorporeal membrane oxygenation (ECMO) instead of mechanical ventilation. Such a device, termed an artificial placenta, was first researched over 50 years ago. AP models vary, but all incorporate ECMO involving the umbilical vessels, lack of mechanical ventilation, and low partial pressure of oxygen to preserve fetal circulation. Current research has foc...

ECMO in neonates: Neuroimaging findings and outcome
Abstract: Extracorporeal membrane oxygenation (ECMO) is a rescue therapy for newborns with severe but reversible respiratory failure. Although ECMO has significantly improved survival, it is associated with substantial complications, of which intracranial injuries are the most important. These injuries consist of hemorrhagic and non-hemorrhagic, ischemic lesions. Different from the classical presentation of hemorrhages in preterm infants, hemorrhages in ECMO-treated newborns are mainly parenchymal and with a high percentage in the posterior fossa area. There are conflicting data on the predominant occurrence of cerebral le...

Update on PPHN: Mechanisms and treatment
Abstract: Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome of failed circulatory adaptation at birth, seen in about 2/1000 live born infants. While it is mostly seen in term and near-term infants, it can be recognized in some premature infants with respiratory distress or bronchopulmonary dysplasia. Most commonly, PPHN is secondary to delayed or impaired relaxation of the pulmonary vasculature associated with diverse neonatal pulmonary pathologies, such as meconium aspiration syndrome, congenital diaphragmatic hernia, and respiratory distress syndrome. Gentle ventilation strategies, lung recruitment, i...

Update and outcomes in extracorporeal life support
Abstract: The Extracorporeal Life Support Organization Registry has collected outcome data of almost 56,000 patients receiving extracorporeal life support (ECLS) over the last 24 years. The use of neonatal respiratory ECLS declined from a peak of 1516 cases in 1992 to 750–865 cases from 2008 to 2012. The 26,583 cases of neonatal respiratory ECLS (75% survival) represent the largest patient population in the registry. Indicating the rapid growth in other patient populations, 2013 marks the first year where the number of neonatal respiratory ECLS cases is less than 50% of the registry. Stagnant at ~200 cases/year from 1993...

As with all historic events, there are many crossroads that occur, with key elements and/or people at each turn, directing the movement forward. In the late 1940 and early 1950s the fields of cardiovascular surgery and nephrology were emerging, with leaders in the fields working on artificial systems to support the heart for cardiac surgery and the kidney during renal failure. In 1944, investigators working on an artificial membrane for dialysis observed that blood became oxygenated as it passed through the cellophane chambers of their membrane. This historic observation led to the recognition by those involved in the fast...

Highly efficient respiratory motion compensated free‐breathing coronary mra using golden‐step Cartesian acquisition
ConclusionWe demonstrate the feasibility of a new 3D affine respiratory motion correction technique for Cartesian whole‐heart CMRA that achieves 100% scan efficiency and therefore a predictable acquisition time. This approach yields image quality comparable to that of an 8‐mm navigator‐gated acquisition with lower scan efficiency. Further evaluation of this technique in patients is now warranted to determine its clinical use.J. Magn. Reson. Imaging 2014;. © 2014 Wiley Periodicals, Inc.

Airway, but not serum or urinary, levels of YKL-40 reflect inflammation in early cystic fibrosis lung disease
Conclusions: This study demonstrates that levels of the chitinase-like protein YKL-40 reflect airway inflammation and infection in early CF lung disease. The lack of increased YKL-40 in serum in the absence of systemic inflammation limits the benefit of this potential biomarker in early disease. (Source: BMC Pulmonary Medicine - Latest articles)

Innate immune recognition of respiratory syncytial virus infection.
Abstract Respiratory syncytial virus (RSV) is the leading cause of respiratory infection in infants and young children. Severe clinical manifestation of RSV infection is a bronchiolitis, which is common in infants under six months of age. Recently, RSV has been recognized as an important cause of respiratory infection in older populations with cardiovascular morbidity or immunocompromised patients. However, neither a vaccine nor an effective antiviral therapy is currently available. Moreover, the interaction between the host immune system and the RSV pathogen during an infection is not well understood. The innate i...

Assessing the Utility of FDG PET-CT after Stereotactic Body Radiotherapy for Early Stage Non-small Cell Lung Cancer.
CONCLUSIONS: FDG PET-CT 3 months following treatment of NSCLC with SBRT was a specific but insensitive test for detection of recurrence or treatment failure. Serial CT scans should be used for early surveillance following SBRT while reserving FDG PET-CT to define suspected metastatic disease, evaluate new abnormalities on CT scan, or possibly to reassess later in the follow up period after radiation related inflammation subsides.

Do Field Walking Tests Produce Similar Cardiopulmonary Demands to an Incremental Treadmill test in Obese Individuals with Treated Obstructive Sleep Apnea?
CONCLUSION The ISWT can be used, instead of an ITM and in preference to the 6MWT, to assess cardio-respiratory fitness for a cohort of obese people with treated OSA. However, the imprecision of the agreement in V˙O2pk between the ITM and ISWT means they cannot be used interchangeably in an individual. ClinicalTrials.gov identifier: NCT01930513.

Is influenza-like illness a useful concept and an appropriate test of influenza vaccine effectiveness?
CONCLUSIONS: The working diagnosis of ILI presumes influenza may be involved until proven otherwise. Health care workers would benefit by renaming the WHO and CDC ILI symptoms and signs as "acute respiratory illness" and using the WHO acute severe respiratory illness definition. This renaming would shift attention to identify the viral and bacterial pathogens in cases and epidemics, identify new pathogens, implement vaccination plans appropriate to the identified pathogens, and estimate workload during the viral season.

Central role of PAFR signaling in ExoU‐induced NF‐κB activation
Summary ExoU is an important virulence factor in acute Pseudomonas aeruginosa infections. Here, we unveiled the mechanisms of ExoU‐driven NF‐κB activation by using human airway cells and mice infected with P. aeruginosa strains. Luciferase reporter assays showed that PAFR was crucially implicated in the activation of the canonical NF‐κB pathway. Confocal microscopy of lungs from infected mice revealed that PAFR‐dependent NF‐κB activation occurred mainly in respiratory epithelial cells, and reduced p65 nuclear translocation was detected in mice PAFR‐/‐ or treated with the PAFR antagonist WEB 2086. Several e...

An Enzyme-Linked Immunospot Assay for the Detection of Human Respiratory Syncytial Virus F-Specific IFNγ-producing T Cells.
Abstract Respiratory syncytial virus (RSV) causes significant disease in elderly adults and we have previously reported that individuals 65 years of age and older have reduced RSV F-specific interferon gamma (IFNγ)-producing T cells compared to healthy younger adults. To measure RSV F-specific memory T cell responses in the elderly following infection or vaccination, we optimized and qualified an IFNγ enzyme-linked immunospot (ELISPOT) assay. Since peripheral blood mononuclear cells (PBMC) from the elderly could be more fragile, we established optimal cryopreservation techniques and minimal viability acceptance c...

Inhibition of mTORC1 induces loss of E-cadherin through AKT/GSK-3ß signaling-mediated upregulation of E-cadherin repressor complexes in non-small cell lung cancer cells
Conclusions: In conclusion, selective inhibition of mTORC1 leads to hyperactivation of the AKT/GSK-3β pathway, inducing E-cadherin repressor complexes and EMT. These findings imply the existence of a feedback inhibition loop of mTORC1 onto mTORC2 that plays a role in the homeostasis of E-cadherin expression and EMT, requiring caution in the clinical use of rapalog and selective mTORC1 inhibitors.
