BACKGROUND: This study was conducted to determine the potential of the monocytes educated with rat bone marrow mesenchymal stem cell-derived conditioned medium (MCM) in ameliorating animal model of asthma. METHODS: Chronic asthma was induced in the BALB/c mice using ovalbumin (OVA) sensitization. The monocytes were isolated from blood of mice and supplemented with 50% MCM or negative control media. After 24 h, the cells were designated as "non-educated or educated"...

The carbonic anhydrase (CA) inhibitors, acetazolamide and its structurally similar analogue, methazolamide prevent or reduce hypoxic pulmonary vasoconstriction (HPV) in dogs and humans in vivo, by a mechanism unrelated to CA inhibition. In rodent blood and isolated blood vessels, Aamand et al. (2009) reported that inhibition of CA led to increased generation of nitric oxide (NO) from nitrite and vascular relaxation in vitro. We tested the physiological relevance of augmented NO generation by CA from nitrite with acetazolamide in anaesthetized pigs during alveolar hypoxia in vivo...

OBJECTIVE: Periostin, a matricellular protein, is produced from airway epithelial cells and lung fibroblasts by IL-13. It has been suggested that periostin is involved in allergic inflammation and fibrosis. However, the usefulness of serum periostin measurement in the assessment of airway inflammation and remodeling and management of asthmatic patients is still debated. We aimed to determine whether serum periostin levels reflect eosinophilic airway inflammation and airway remodeling in asthma...

Airway eosinophilic inflammation is a key feature of type 2-high asthma. The role of epithelial miRNA in airway eosinophilic inflammation remains unclear. We examined the expression of miR-221-3p in bronchial brushings, induced sputum and plasma from 77 symptomatic, recently diagnosed steroid-naïve subjects with asthma and 36 healthy controls by quantitative PCR, and analyzed the correlation between miR-221-3p expression and airway eosinophilia. We found that epithelial, sputum and plasma miR-221-3p expression was significantly decreased in subjects with asthma...

"Erva cidreira" (Lippia alba (Mill.) N. E. Brown) is popular for its therapeutic properties, especially its sedative properties. Such properties led to the discovery of the anesthetic action of Lippia alba essential oil in fish culture. The objective of this study was to evaluate the genotoxic effect of Lippia alba essential oil in fish and mammals. The oil was extracted by hydrodistillation with a Clevenger apparatus and analyzed by gas chromatography coupled to mass spectrometry (GC-MS), where the compounds linalool, eucalyptol, γ-muurolene, and caryophyllene were identified as the most abundant compounds...

The commonest cause of pulmonary hypertension (PH) is left heart disease (LHD). The current classification system for definitions of PH-LHD is under review. We therefore performed prospective in-depth invasive hemodynamic phenotyping in order to assess the site of increased pulmonary vascular resistance (PVR) in PH-LHD subsets.Based on pulmonary artery occlusion waveforms yielding an estimate of the effective capillary pressure (P c' ), we partitioned PVR in larger arterial (R up , upstream resistance) and small arterial plus venous components (R ds , downstream resistance)...

PURPOSE: Inhaled nitric oxide (iNO) is a pulmonary vasodilator that is approved for use in term and near-term neonates with hypoxic respiratory failure associated with evidence of pulmonary hypertension. However, it is commonly used in infants and children to treat a variety of other cardiopulmonary diseases associated with pulmonary hypertension and hypoxic respiratory failure. In critically ill children, iNO therapy may be continued for a prolonged period, and this increases the risk for adverse consequences including toxicity and unnecessary costs...

Respiratory failure associated with hematopoietic stem cell transplantation (HSCT) has been considered a contraindication for use of extracorporeal membrane oxygenation (ECMO) at many centers. We describe a child with neuroblastoma and hypoxemic respiratory failure following HSCT who was successfully managed with veno-venous (VV) ECMO. The patient was an 18-month-old female with high-risk neuroblastoma status post tumor resection, chemotherapy, autologous HSCT, and primary site radiation. On day 113 posttransplant while receiving maintenance immunotherapy, she had an acute respiratory decompensation because of rhinovirus, aspiration pneumonia, and capillary leak syndrome...

BACKGROUND: We sought to compare treatment satisfaction with inhaled medications among asthmatics using a metered-dose inhaler (MDI) or a dry-powder inhaler (DPI), and to correlate satisfaction with treatment adherence, pulmonary function, and airway inflammation. METHODS: Spirometry, fraction of expired nitric oxide (FENO ), and asthma control were assessed in 200 adult subjects with asthma (69 men, 131 women) using MDI or DPI. Treatment satisfaction with inhaled therapy was assessed with the Treatment Satisfaction Questionnaire for Medication (TSQM) in 4 domains: Effectiveness, Side Effects, Convenience, and Global Satisfaction...

50 years ago, Northway described Broncopulmonary Dysplasia (BPD) in preterm infants exposed to mechanical ventilation. Since then, their survival has increased, nevertheless a "new BPD" has appeared and its incidence has not diminished. One of the characteristics of this pathology is the the abnormal vascular remodeling, which in its most severe expression is known as Pulmonary Hyper tension (PH); with an incidence of 17% in patients with BPD, which is proportional to the severity of the disease (33% in severe BPD), and as mortality factor (up to 48% 2-year mortality in PH-BPD)...

BACKGROUND: The single-centre double-blind, randomised controlled Managing Asthma in Pregnancy (MAP) trial in Newcastle, Australia, compared a treatment algorithm using the fraction of exhaled nitric oxide (FeNO) in combination with asthma symptoms (FeNO group) against a treatment algorithm using clinical symptoms only (clinical group) in pregnant asthmatic women (ANZ Clinical Trials Registry, number 12607000561482). The primary outcome was a 50% reduction in asthma exacerbations during pregnancy in the FeNO group...

OBJECTIVE: To determine the characteristics of term infants with persistent pulmonary hypertension of the newborn (PPHN) associated with moderate or severe hypoxic ischemic encephalopathy (HIE). METHODS: We compared infants with and without PPHN enrolled in 2 randomized trials of therapeutic hypothermia: the induced hypothermia trial of cooling to 33.5°C for 72 hours vs normothermia, and the "usual-care" arm (33.5°C for 72 hours) of the optimizing cooling trial...

3D printers are increasingly run at home. Nanoparticle emissions from those printers have been reported, which raises the question whether adverse health effects from ultrafine particles (UFP) can be elicited by 3D printers. We exposed 26 healthy adults in a single-blinded, randomized, cross-over design to emissions of a desktop 3D printer using fused deposition modeling (FDM) for one hour (high UFP-emitting acrylonitrile butadiene styrene (ABS) versus low-emitting polylactic acid (PLA)). Before and after exposures, cytokines (IL-1β, IL-6, TNF-α, INF-γ) and ECP in nasal secretions, exhaled nitric oxide (FeNO), urinary 8-isoprostaglandin F2α (8-iso PGF2α ) and self-reported symptoms were assessed...

BACKGROUND: Excessive supplemental oxygen exposure in the neonatal intensive care unit (NICU) can be associated with oxygen-related toxicities, which can lead to negative clinical consequences. Use of inhaled nitric oxide (iNO) can be a successful strategy for avoiding hyperoxia in the NICU. iNO selectively produces pulmonary vasodilation and has been shown to improve oxygenation parameters across the spectrum of disease severity, from mild to very severe, in neonates with hypoxic respiratory failure associated with persistent pulmonary hypertension of the newborn...

The 21st Congress for the International Society for Aerosols in Medicine included, for the first time, a session on Pulmonary Delivery of Therapeutic and Diagnostic Gases. The rationale for such a session within ISAM is that the pulmonary delivery of gaseous drugs in many cases targets the same therapeutic areas as aerosol drug delivery, and is in many scientific and technical aspects similar to aerosol drug delivery. This article serves as a report on the recent ISAM congress session providing a synopsis of each of the presentations...

BACKGROUND: Chitinase-3-like 1 (CHI3L1) is a glycoprotein elevated in paediatric severe malaria, and an emerging urinary biomarker of acute kidney injury (AKI). Based on the hypothesis that elevated CHI3L1 levels in malaria are associated with disease severity, the relationship between plasma CHI3L1 levels, AKI and mortality was investigated in Ugandan children enrolled in a clinical trial evaluating inhaled nitric oxide (iNO) as an adjunctive therapy for severe malaria. METHODS: Plasma CHI3L1 levels were measured daily for 4 days in children admitted to hospital with severe malaria and at day 14 follow up...

BACKGROUND: Inhaled nitric oxide (iNO) is increasingly prescribed to extremely premature neonates with respiratory distress syndrome (RDS). Most of this off-label use occurs during the first week of life. We studied this practice, hypothesizing that it would not be associated with improved survival. METHODS: We queried the Pediatrix Medical Group Clinical Data Warehouse to identify all neonates born at 22 to 29 weeks' gestation from 2004 to 2014. In our study sample, we included singletons who required mechanical ventilation for treatment of RDS and excluded those with anomalies...
