The small airways of the lungs are commonly affected in pediatric and adult asthma. Small airways disease has been related to asthma control, severity, and risk of exacerbation. Diagnosis of small airways disease can be best made through evaluation of surgical lung specimens. Noninvasive techniques including spirometry, plethysmography, nitrogen washout, impulse oscillometry, and cross-sectional imaging have been utilized to assess and infer the extent of small airways disease in asthma and can be used longitudinally to assess response to treatment...

BACKGROUND AND OBJECTIVE: Animal models using rodents are frequently used for the purpose of practicing microvascular anastomosis - an essential technique in cerebrovascular surgery. However, safely and efficiently exposing rat's target vessels is technically difficult. Such difficulty may lead to excessive hemorrhage and shorten animal survival. This limits the ability to perform multiple anastomoses on a single animal and may increase the overall training time and costs. We report our model for microsurgical bypass training in rodents in two consecutive articles...

Healthcare facilities (HF) represent an at-risk environment for legionellosis transmission occurring after inhalation of contaminated aerosols. In general, the control of water is preferred to that of air because, to date, there are no standardized sampling protocols. Legionella air contamination was investigated in the bathrooms of 11 HF by active sampling (Surface Air System and Coriolis(®)μ) and passive sampling using settling plates. During the 8-hour sampling, hot tap water was sampled three times. All air samples were evaluated using culture-based methods, whereas liquid samples collected using the Coriolis(®)μ were also analyzed by real-time PCR...

This study describes the development of new mannosylated Solid Lipid Nanoparticle assemblies (SLNas) delivering rifampicin for an inhaled treatment of tuberculosis. SLNas were surface engineered with mannose residues to recognize mannose receptors located on infected alveolar macrophages and facilitate cell internalization. Two sets of SLNas were produced by the melt emulsifying technique using biocompatible lipid components, i.e. cholesteryl myristate combined with palmitic acid (PA set) or tripalmitin (TP set), in the presence of the targeting moiety, methyl α-d-mannopyranoside...

INTRODUCTION: Many patients with asthma remain poorly controlled despite the use of inhaled corticosteroids and long-acting beta agonists. Poor control may arise from inadequate adherence, incorrect inhaler technique or because the condition is refractory. Without having an objective assessment of adherence, clinicians may inadvertently add extra medication instead of addressing adherence. This study aims to assess if incorporating objectively recorded adherence from the Inhaler Compliance Assessment (INCA) device and lung function into clinical decision making provides more cost-effective prescribing and improves outcomes...

As pulmonary drug delivery is extended from low doses to high doses, physicochemical characteristics of the active pharmaceutical ingredient gain importance in the development of dry powder inhalers. Therefore, the present work aims to understand the impact of distinct engineering techniques on the process induced physicochemical characteristics of salbutamol sulphate particles over time. The particle engineering techniques chosen were jet-milling and spray-drying, two well used processes in the production of predominately crystalline and amorphous inhalable particles, respectively...

BACKGROUND: Thoracic surgery requires the effective collapse of the non-ventilated lung. In the majority of cases, we accomplished, accelerated lung collapse using a double-lumen tube (DLT). We hypothesized that using the two-minute disconnection technique with a DLT would improve lung collapse during subsequent one-lung ventilation. METHODS: Fifty patients undergoing thoracoscopic surgery with physical classification I or II according to the American Society of Anesthesiologists were randomly divided into two groups for respiratory management of one-lung ventilation (OLV)...

The total circulatory arrest (CA) is necessary to achieve optimal surgical conditions in certain aortic pathologies, especially in those affecting the ascending aorta and aortic arch. During this procedure it is necessary to protect all the organs of ischemia, especially those of the central nervous system and for this purpose several strategies have been developed. The first and most important protective method is systemic hypothermia. The degree of hypothermia and the route of application have been evolving and currently tend to use moderate hypothermia (MH) (20...

Nitrous oxide and midazolam have been used as sedative agents to decrease fear and anxiety associated with dental procedures. Although these agents have been widely used individually, the combination of the two is also commonly used. Four clinical trials were identified that compared the combination technique with the individual use of the drugs. The standardized mean difference (SMD) for each outcome measure was considered for final analysis. Three studies with 534 participants were included in the final meta-analysis, and the SMD [95% CI] was obtained as -0...

Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a reliable and commonly established technique, enabling real-time guidance of transbronchial needle aspiration of mediastinal and hilar structures and parabronchial lung masses. As EBUS-TBNA became more available and adopted by clinicians, questions emerged about the optimal performance of the procedure. Although EBUS is considered safe, there are few complications that could occur during the test, correlated with both the procedure itself and the patient's characteristics...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) severely hinders quality of life for those affected and is costly to the health care system. Care gaps in areas such as pharmacotherapy, inhaler technique, and knowledge of disease are prevalent, particularly for vulnerable populations served by community clinics. Non-professionally licensed health coaches have been shown to be an effective and cost-efficient solution in bridging care gaps and facilitating self-management for patients with other chronic diseases, but no research to date has explored their efficacy in improving care for people living with COPD...

Legionnaires' disease, predominantly caused by the bacterium Legionella pneumophila, has increased in prevalence worldwide. The most common mode of transmission of Legionella is inhalation of contaminated aerosols, such as those generated by cooling towers. Simple, rapid and accurate methods to enumerate L. pneumophila are required to prevent the spread of this organism. Here, we applied a microfluidic device for on-chip fluorescent staining and semi-automated counting of L. pneumophila in cooling tower water...
