Nani Kadrichu, Derek Daniher
BACKGROUND: In an in vitro model of mechanical ventilation with gravity-dependent filter position we observed artificially high delivered doses resulting from liquid droplet collection and precipitation of aerosolized drug. We sequentially modified the model to obtain accurate reproducible measurements of delivered dose and particle size at endotracheal tube exit. METHODS: Stepwise changes in the model included (1) altering the endotracheal tube position to a gravity-independent position, (2) adding fluid traps, (3) humidifying air near the test lung, and (4) simplifying test lung and filters...

Mechanical ventilation has the potential to increase inflammation in both healthy and injured lungs. Several animal studies have shown that variable ventilation recruits the lungs and reduces inflammation. However, it is unclear which cellular mechanisms are involved in those findings. We hypothesized that variable stretch of LPS-stimulated alveolar epithelial cells (AECs) reduces the production of pro-inflammatory cytokines compared to non-variable stretch. AECs were subjected to non-variable or variable cyclic stretch (sinusoidal pattern), with and without LPS stimulation...

Over the last 20 years, the Kirk R. Smith research group at the University of California Berkeley-in collaboration with Electronically Monitored Ecosystems, Berkeley Air Monitoring Group, and other academic institutions-has developed a suite of relatively inexpensive, rugged, battery-operated, microchip-based devices to quantify parameters related to household air pollution. These devices include two generations of particle monitors; data-logging temperature sensors to assess time of use of household energy devices; a time-activity monitoring system using ultrasound; and a CO₂-based tracer-decay system to assess ventilation rates...

BACKGROUND: Patients with severe chronic obstructive pulmonary disease (COPD) are at a higher risk for postoperative respiratory complications. Despite the benefits of a minimally invasive approach, laparoscopic pneumoperitoneum can substantially reduce functional residual capacity and raise alveolar dead space, potentially increasing the risk of respiratory failure which may be poorly tolerated by COPD patients. This raises controversy as to whether open techniques should be preferentially employed in this population...

BACKGROUND: Ethylene glycol intoxication causes severe metabolic acidosis and acute kidney injury. Fomepizole has become available as its antidote. Nevertheless, a prompt diagnosis is not easy because patients are often unconscious. Here we present a case of ethylene glycol intoxication who successfully recovered with prompt hemodialysis. CASE PRESENTATION: A 52-year-old Japanese male was admitted to a local hospital due to suspected food poisoning. The patient presented with nausea and vomiting, but his condition rapidly deteriorated, with worsening conscious level, respiratory distress requiring mechanical ventilation, hypotension, and severe acute kidney injury...

Hypoglossal nerve palsy induces palsy in the ipsilateral lingual muscles, resulting in tongue deviation and articulation disorder. It is a rare condition that may stem from a variety of causes. Therefore, it is important to consider the possible causes of hypoglossal nerve palsy related to surgery or anesthesia, including intubation, the surgical positions, and mask ventilation during recovery.

Indoor microbial communities have important implications for human health, especially in health-care institutes (HCIs). The factors that determine the diversity and composition of microbiomes in a built environment remain unclear. Herein, we used 16S rRNA amplicon sequencing to investigate the relationships between building attributes and surface bacterial communities among four HCIs located in three buildings. We examined the surface bacterial communities and environmental parameters in the buildings supplied with different ventilation types and compared the results using a Dirichlet multinomial mixture (DMM)-based approach...

BACKGROUND: Lung clearance index (LCI) detects early ventilation inhomogeneity and has been suggested as sensitive endpoint in multicenter intervention trials in infants and preschoolers with cystic fibrosis (CF). However, the feasibility of multicenter LCI in this age group has not been determined. We, therefore, investigated the feasibility of LCI in infants and preschoolers with and without CF in a three-center setting. METHODS: Following central training, standardized SF6-MBW measurements were performed in 73 sedated children (10 controls, 49 with CF and 14 with other lung diseases), mean age 2...

Second-hand tobacco smoke (SHS) is an avoidable and harmful exposure in the workplace but >25000 prison staff continue to be exposed on a daily basis in the UK and many more worldwide. SHS exposures in prisons are incompletely understood but may be considerable given the large proportion of smoking prisoners and limited ventilation. This study characterized the exposure of prison staff to SHS in all 15 prisons in Scotland using multiple methods. Exposure assessment strategies included 6-day area measurement of fine Particulate Matter (PM2...

Background: Occupational exposure to methylene bisphenyl isocyanate (MDI) presents serious worker health concerns as it may lead to short- and long-term health effects such as asthma, airway irritation, hypersensitivity pneumonitis, and irritation of skin and mucous membranes. While studies of worker isocyanate exposures during vehicle painting activities are widespread, few studies have investigated the spray-on truck bed-liner (STBL) industry. The purpose of this study was to determine the effectiveness of several ventilation system variables and process characteristics in controlling MDI concentrations in the STBL industry...

Sepsis is a systemic inflammatory reaction, which is aggravated by aspects of the immune response that are thought to be inhibited by Omega-3 fatty acids. The aim of the present study was to determine if Omega-3 fatty acid could modulate immunological function and improve survival rate among septic patients with intestinal dysfunction. A total of 48 mechanically ventilated patients with intestinal dysfunction were included in this prospective, randomized and single-blind clinical study. Patients were randomly divided into control (group A) and treatment groups (group B)...

Ventilator-associated pneumonia (VAP) is a common nosocomial infection in neonatal intensive care units with high morbidity and mortality. Bacterial biofilm in the endotracheal tube (ET) provides a notable and persistent source of pathogens that may cause VAP, and thus is important for VAP detection. However, during intubation microbial investigations in ET, samples are unavailable due to the infeasibility of collecting ET samples during intubation of neonates. It is therefore of great importance to find alternative sources of samples that can help identify the ET biofilm flora...

The present study aimed to evaluate the role of autophagy in the protective effect of dexmedetomidine in lung injury caused by ischemia-reperfusion (IR) in rats. In total 48 adult male Sprague-Dawley rats were randomly divided into 6 groups (n=8) as follows: i) Sham group; ii) the IR group; iii) IR + 1 µg/kg dexmedetomidine preconditioning group (pre-LD); iv) IR + 10 µg/kg dexmedetomidine preconditioning group (pre-HD); v) IR + 1 µg/kg dexmedetomidine postconditioning group (post-LD); and vi) IR + 10 µg/kg dexmedetomidine postconditioning group (post-HD)...

In patients with home ventilation, there is a markedly higher probability for lower respiratory infections or pneumonia and severe courses due to comorbidity. Tracheobronchitis and pneumonia are often difficult to distinguish. Tracheobronchitis with pronounced secretion which can't be controlled otherwise can be an indication for antimicrobial therapy.There are no data available in order to establish a recommendation for the initial empiric calculated antimicrobial therapy in patients with home ventilation...

The care of patients with extraclinical mechanical ventilation has to be improved particularly with regard to their specialist care. One care option is the empowering of clinicians at the respiratory centers to enable ambulant care of patients and home visits. An intersectoral linkage in the form of transfer management is the basis for competent coordination. Aim is to ensure the necessary multidisciplinary collaboration in the outpatient care of multimorbid chronically ill patients. For the optimal care of chronically ill patients, sectoral limits should become more permeable...

The prognosis of patients receiving home mechanical ventilation is very heterogeneous and depends on the underlying disease, the degree of respiratory dependency and the comorbidities. Due to the severe chronic diseases, the initiation of a long-term NIV must be done during an inpatient treatment. Two recently published randomized controlled trials using more aggressive forms of NPPV targeted at normalizing hypercapnic PaCO2 values, showed improved long term survival also in patients with an underlying diagnosis of COPD...

Obesity, a worldwide epidemic, has become a major health burden because it is usually accompanied by an increased risk for insulin resistance, diabetes, hypertension, cardiovascular diseases, and even some kinds of cancer. It also results in associated increases in healthcare expenditures and labor and economic consequences. There are also other fields of medicine and biology where obesity or being overweight play a major role, such as high-altitude illnesses (acute mountain sickness, hypoxic pulmonary hypertension, and chronic mountain sickness), where an increasing relationship among these two morbid statuses has been demonstrated...
