Bronchopulmonary Dysplasia (BPD) represents a major threat to the short and long-term health and development of very preterm infants. Unfortunately, despite much study and progress in neonatology in recent years and some modest improvements in survival, both the incidence and severity of BPD remain frustratingly stable (1).

STUDY OBJECTIVE: Laparoscopic sleeve gastrectomy is commonly performed under total intravenous anaesthesia (TIVA) or balanced anaesthesia using an intravenous and inhalation agent. It is still unclear which anaesthesia regimen is better for this group of patients. The present study has been conducted to compare the use of the inhalation anaesthesia technique using desflurane with the TIVA technique, using propofol and dexmedetomidine. DESIGN: Prospective, randomised, double-blinded study...

Dry powder inhalers containing the budesonide/formoterol combination have currently a well-established position among other inhaled products. Even though their efficacy mainly depends on the local concentrations of the drug they deliver within the lungs, their safety profile is directly related to their total systemic exposure. The aim of the present investigation was to explore the absorption and disposition kinetics of the budesonide/formoterol combination delivered via two different dry powder inhalers in asthma patients...

The human nose takes primary responsibility for preconditioning inhaled air. Numerous pathologies can affect the physiology of the nose. The beginnings of flow analyzes were carried out with three-dimensional casting models and differently colored liquids. Temperature and humidity could not be taken into account. Today, much more complex analyzes are possible using computational fluid dynamics (CFD), which are based on three-dimensional models generated from computed tomography (CT) or magnetic resonance imaging (MRI) datasets...

The purpose of this report was to review the state of asthma diagnosis and treatment in China and to examine challenges in achieving earlier diagnosis and treatment. The prevalence of asthma in children in China has increased over past decades, and data published in 2013 indicated a prevalence of 3.0% in children aged 0-14 years. Although this prevalence has increased, the percentage of children with acute asthma attacks decreased from 86% in 2000 to 77% in 2010, and the frequency of hospitalizations for asthma attacks decreased from 54...

A large number of studies have demonstrated that inhalation anesthetic isoflurane induced neural cell death by apoptosis in various cell and animal models. Emulsified isoflurane (EIso) is a new type of intravenous preparation of isoflurane that attracts increasing research attention as a promising clinical agent due to its both advantages as an intravenous and inhalation anesthetics medication. However, its safety and underlying molecular mechanism of neurotoxicity largely remain unknown. Therefore, it is meaningful to investigate the safety of EIso and to further elucidate its mechanism of anesthetic neurotoxicity...

Allergen immunotherapy is effective in patients with IgE-dependent allergic rhinitis and asthma. When immunotherapy is given continuously for 3 years, there is persistent clinical benefit for several years after its discontinuation. This disease-modifying effect is both antigen-specific and antigen-driven. Clinical improvement is accompanied by decreases in numbers of effector cells in target organs, including mast cells, basophils, eosinophils, and type 2 innate lymphoid cells. Immunotherapy results in the production of blocking IgG/IgG4 antibodies that can inhibit IgE-dependent activation mediated through both high-affinity IgE receptors (FcεRI) on mast cells and basophils and low-affinity IgE receptors (FcεRII) on B cells...

Background: Studies have shown that poor shelter or dwelling conditions may lead to deteriorations in health. Those with asthma may be more susceptible to compromised living conditions and stress leading to a higher risk of asthma exacerbations. To describe the asthma control and quality of life of individuals with diagnosed asthma living in a shelter in Damascus, Syria and estimate the prevalence of respiratory symptoms in shelter dwellers without diagnosed asthma. Methods: In this cross-sectional study, all individuals 5 years and older living in Al-Herjalleh shelter with diagnosed asthma were recruited to complete a questionnaire, which included items related to their respiratory symptoms, asthma exacerbations, exposure to asthma triggers, medication use, and health-related quality of life before and since entering the shelter...

In order to minimize an unwanted interference of colloidal drug delivery vehicles with the biophysical functionality of lung surfactant, the surface of polymer nanoparticles was modified with poly(ethylene glycol) (PEGylation). Plain poly(lactide) nanoparticles provoked a statistically relevant decrease in surface activity of the naturally-derived lung surfactant Alveofact®. By contrast, the extent of lung surfactant inhibition induced by PEGylated polymer nanoparticles was significantly attenuated. Here, escalations of the PEG coating layer thickness (>3 nm, with a chain-to-chain distance of ≤4 nm) on the colloidal surface were capable of circumventing bioadverse effects...

Tuberculosis (TB) is a life threatening pulmonary infection caused by Mycobacterium tuberculosis (MTB). Current treatments are complex, lengthy and associated with severe side effects that decrease patient compliance and increase the probability of the emergence of drug resistant strains. Thus, more effective drugs with little to no side effects are needed to diversify the armamentarium against the global TB epidemic. SHetA2, an anticancer compound with null toxicity at doses much higher than the effective dose, was recently discovered to be active against MTB...

BACKGROUND: There are very few options to treat multidrug-resistant bacterial infections in children. A major barrier is the duration and complexity of regulatory trials of new antibiotics. Extrapolation of safety data from adult trials could facilitate drug development for children. OBJECTIVE: We performed a systematic review on the safety of antibiotic clinical trials (CTs) in children (0-18 years) to evaluate the overall quality of safety trials conducted in children and to determine if age-specific adverse events (AEs) could be identified for specific antibiotic classes...

Mycobacterium tuberculosis (Mtb), the etiological agent of human tuberculosis (TB), has plagued humans for thousands of years. TB still remains a major public health problem in our era, causing more than 4,400 deaths worldwide every day and killing more people than HIV. After inhaling Mtb-contaminated aerosols, TB primo-infection starts in the terminal lung airways, where Mtb is taken up by alveolar macrophages. Although macrophages are known as professional killers for pathogens, Mtb has adopted remarkable strategies to circumvent host defenses, building suitable conditions to survive and proliferate...

Redistribution of blood flow across different brain regions, arising from the vasoactive nature of hypercapnia, can introduce errors when examining cerebrovascular reactivity (CVR) response delays. In this study, we propose a novel analysis method to characterize hemodynamic delays in the blood oxygen level dependent (BOLD) response to hypercapnia, and hyperoxia, as a way to provide insight into transient differences in vascular reactivity between cortical regions, and across tissue depths. A pseudo-continuous arterial spin labeling sequence was used to acquire BOLD and cerebral blood flow simultaneously in 19 healthy adults (12 F; 20 ± 2 years) during boxcar CO2 and O2 gas inhalation paradigms...
