INTRODUCTION: The present study describes our experience with the high-flow humidified nasal cannula (HFNC) versus non-invasive ventilation (NIV) in children with severe acute asthma exacerbation (SA). METHODS: An observational study of a retrospective cohort of 42 children with SA admitted to a Pediatric Intensive Care Unit (PICU) for non-invasive respiratory support was made. The primary outcome measure was failure of initial respiratory support (need to escalate from HFNC to NIV or from NIV to invasive ventilation)...

The aim of the present study was to investigate the beneficial effect of polydatin (PD), the glycoside form of resveratrol, on embryo development in vitro. Oocytes were aspirated from ovaries of Korean Hanwoo cows and cultured until Day 8 in a humidified atmosphere of 5% CO2 in air at 38.5°C. Protein and gene expression levels were determined through confocal microscopy and reverse transcription-polymerase chain reaction respectively, whereas the number of total and apoptotic cells in Day 8 blastocysts was determined using Hoechst 33342 staining and terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling...

In South Korea, a cluster of humidifier disinfectant-induced lung injury (HDLI) cases developed between 2006 and 2011. There are no existing reports regarding the rate of humidifier disinfectant (HD) usage in the general population of Korean children. The purpose of this study was to investigate the rate of humidifier and HD usage in the general population of Korean children. This is a general population-based birth cohort multicenter study, Panel Study of Korean Children (PSKC) from 2008, a humidifier and HD-related questionnaire administered to 1577 subjects (809 male, 768 female) in 2015 (n=1577)...

BACKGROUND: High-flow nasal cannula therapy (HFNC) for neonate/infants can deliver up to 10 L/min of heated and humidified gas, and FIO2 can be adjusted to between 0.21 and 1.0. With adults, humidification and actual FIO2 are known to vary according to inspiratory and HFNC gas flow, tidal volume (VT), and ambient temperature. There have been few studies focused on humidification and FIO2 in HFNC settings for neonates/infants, so we performed a bench study to investigate the influence of gas flow, ambient temperature, and respiratory parameters on humidification and actual FIO2 in a neonate/infant simulation...

BACKGROUND: Stem cells are capable of unlimited self-renewal and are able to remain undifferentiated for extended periods of time prior to their differentiation into specific cell lineages. Because of the issues (ethical and religious) involved in the use of embryonic stem cells and the limited plasticity of adult stem cells, an alternative cell source could be foetal stem cells derived from extra-embryonic tissue, which are highly proliferative, grow in vitro and possess interesting immunogenic characteristics...

Background. Noninvasive respiratory support is considered the optimal method of providing assistance to preterm babies with breathing problems, including nasal continuous positive airway pressure (NCPAP) and humidified high flow nasal cannula (HHHFNC). The evidence of the efficacy and safety of HHHFNC used as the primary respiratory support for respiratory distress syndrome (RDS) is insufficient in low- and middle-income countries. Objective. To investigate the effect of heated humidified high flow nasal cannula on neonatal respiratory distress syndrome compared with nasal continuous positive airway pressure...

Co-incineration of sewage sludge in cement kilns can be used for its disposal. In the present study, samples were collected from three cement production runs where sewage sludge and other wastes (e.g. municipal solid waste, waste acid and wet sewage sludge) were co-processed. The samples were analyzed for polychlorinated biphenyls (PCBs). The dioxin-like (dl)-PCB concentrations in the stack gases from run 1, 2, and 3 were 344.6, 548.7, and 104.3 pg m(-3), respectively. The toxic equivalency (TEQs) values for runs 1, 2, and 3 were 5...

BACKGROUND: Typically, live cell analyses are performed outside an incubator in an ambient air, where the lack of sufficient CO2 supply results in a fast change of pH and the high evaporation causes concentration drifts in the culture medium. That limits the experiment time for tens of minutes. In many applications, e.g. in neurotoxicity studies, a prolonged measurement of extracellular activity is, however, essential. NEW METHOD: We demonstrate a simple cell culture chamber that enables stable culture conditions during prolonged extracellular recordings on a microelectrode array (MEA) outside an incubator...

BACKGROUND: Bronchiolitis is the most common lung infection in infants and treatment focuses on management of respiratory distress and hypoxia. High-flow warm humidified oxygen (HFWHO) is increasingly used, but has not been rigorously studied in randomised trials. We aimed to examine whether HFWHO provided enhanced respiratory support, thereby shortening time to weaning off oxygen. METHODS: In this open, phase 4, randomised controlled trial, we recruited children aged less than 24 months with moderate bronchiolitis attending the emergency department of the John Hunter Hospital or the medical unit of the John Hunter Children's Hospital in New South Wales, Australia...

BACKGROUND: Heat and moisture exchangers (HMEs) improve respiratory function after laryngectomy, but there is virtually no information on the benefit of traditional stoma cloths or other covers. METHODS: Two sequential studies were performed: (1) an ex vivo test was used to compare the humidifying capacity of stoma cloths to other coverings; and (2) a 4-week randomized trial was then performed to assess patient acceptability of cloths both alone and with an HME (N = 18)...

Yong-Soon Kim, Sung-Bae Lee, Cheol-Hong Lim
Didecyldimethylammonium chloride (DDAC) is used in many types of biocidal products including tableware, carpets, humidifiers, and swimming pools, etc. In spite of increased chances of DDAC exposure through inhalation, studies on the inhalation toxicity of DDAC are not common even though the toxicity of DDAC might be significantly higher if it were to be administered through routes other than the respiratory system. DDAC aerosols were exposed to Sprague-Dawley rats in whole body exposure chambers for a duration of 13 weeks...

BACKGROUND: During anesthesia, as compared with intensive care, the time of the tracheal intubation is much shorter. An inhaled gas minimum humidity of 20 mgH2O.L-1 is recommended to reduce the deleterious effects of dry gas on the airways during anesthesia with tracheal intubation. The Fabius GS Premium® anesthesia workstation (Dräger Medical, Lübeck, Germany) has a built-in hotplate to heat gases in the breathing circuit. A heat and moisture exchanger (HME) is used to further heat and humidify the inhaled gas...

BACKGROUND: Perioperative thermal disturbances during orthotopic liver transplantation (OLT) are common. We hypothesized that in patients undergoing OLT the use of a humidified high flow CO2 warming system maintains higher intraoperative temperatures when compared to standardized multimodal strategies to maintain thermoregulatory homeostasis. METHODS: We performed a randomized pilot study in adult patients undergoing primary OLT. Participants were randomized to receive either open wound humidification with a high flow CO2 warming system in addition to standard care (Humidification group) or to standard care alone (Control group)...

After the initial investigations of Korean CDC in 2011, more than 1,000 suspicious cases of humidifier disinfectant victims were subsequently reported up to 2015, and numbers are still increasing dramatically in 2016 in the midst of prosecutor's office investigation. In this study, we tried to summarize the current understandings of humidifier disinfectant related health effects based upon systemic review of published epidemiologic studies and toxicology investigations. Published studies of humidifier disinfectants were searched through 'pubmed' and 'toxline'?under the heading of 'humidifier disinfectant', and related reports were identified from the references and published report list of regulatory agencies including Korean National Institute of Environmental Research, US Environmental Protection Agency, and EU European Chemicals Agency...

According to previous survey, about 2 million of people were expected to suffer from toxic effects due to humidifier disinfectant, regardless of healing or not. Extremely small group are recognized as humidifier disinfectants??victims. Up to now, previous research tried to focus on interstitial fibrosis on terminal bronchiole because it is specific finding, compared with other diseases. To figure out overall effects from humidifier disinfectants, we recommend adverse outcome pathways (AOPs) as new approach...

BACKGROUND: Concerns about indoor residential humidity have largely centered on dampness prevention. Overly dry air, however, may favor the survival of some viruses and hence respiratory infections. Many residents employ portable humidifiers to humidify their home environment, yet the effect of these humidifiers on indoor humidity is not known. METHODS: We monitored indoor temperature and humidity in 34 apartments in New York City during winter 2014-2015. We combined information from the monitors with surveyed information on building, household, and apartment-level factors and with information on household humidifier use...

BACKGROUND: Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) was introduced to adult anaesthesia to improve the safety of airway management during apnoea before intubation. The objective of our study was to determine whether THRIVE safely prolongs apnoeic oxygenation in children. METHODS: This was a randomized controlled trial in 48 healthy children, with normal airways and cardiorespiratory function, in age groups 0-6 and 7-24 months, 2-5 and 6-10 yr old, presenting for elective surgery or imaging under general anaesthesia...
