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...

This review discusses recent developments in the manufacture of inhalable dry powder formulations. Pulmonary drugs have distinct advantages compared with other drug administration routes. However, requirements of drugs properties complicate the manufacture. Control over crystallization to make particles with the desired properties in a single step is often infeasible, which calls for micronization techniques. Although spray drying produces particles in the desired size range, a stable solid state may not be attainable...

Poor inhaler technique and inferior asthma outcomes are evident in older adults. Reviews comparing metered dose inhaler (MDI) and dry powder inhaler (DPI) techniques across older adults and younger cohorts are scarce. This systematic review aimed to determine whether differences exist between such cohorts with regards to the number and type of MDI and DPI errors made. A systematic literature search was conducted in Embase, Medline and PubMed from July 1 to December 31, 2016. Studies were selected in accordance with preset inclusion criteria, relevant data were extracted, and quality was assessed with validated checklists...

OBJECTIVES: A novel gas chromatography-mass spectrometry (GC-MS) method has been developed to quantify salbutamol in micro-volumes (10 µL) of blood. A potential application is paediatric therapeutic dose monitoring (TDM) in acute severe asthma. METHODS: At presentation, the children receive multiple doses of salbutamol (inhaled, nebulised and occasionally intravenous) but it is difficult to distinguish children who do not respond to treatment because of inadequate concentrations from those with toxicity, as symptoms are similar...

Ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in hair are effective direct biomarkers of ethanol ingestion, whose analytical determination can be used to discriminate between chronic and occasional ethanol intake. Ethanol is a compound widely used in some workplaces (e.g., clinics, hospitals) and is present in considerable amounts in mouthwash for oral cleaning, medications, cosmetic products, hydro-alcoholic disinfectants and antiseptics for hands. This study examined the ethyl alcohol exposure derived from hand disinfectants (in gel form) by simulating the typical occupational situation of medical-health workers (healthcare workers, nurses, surgeons, etc...

Pulmonary diseases, such as asthma and chronic obstructive pulmonary disease (COPD), are common in older people. Treatment principles are well established in this group of patients; however, inadequate training and improper inhaler techniques often results in poor treatment outcomes. Healthcare professionals often do not have the required knowledge about the most common inhaler devices. Age-related conditions like cognitive ability and physical strength would also impact on the inhaler usage. Pharmacokinetics and pharmacodynamics may be affected by physiological changes, like impaired renal and hepatic functions and reduced lung functions...

Nonadherence to asthma medications is well recognized. Interventions to improve adherence, however, have been only moderately successful and are not often adopted because of limited provider time, training, or institutional support. The potential for mobile communication technology to improve adherence has gathered sharply growing interest. Technology-based adherence tracking devices have been in existence for almost 3 decades, but have only recently reached a level of reliability and utility to be considered in allergy practice...

Contrary to traditional planar flexible piezoelectric nanogenerators (PNGs), highly adaptable hemispherical shape-flexible piezoelectric composite strip (HS-FPCS) based PNGs are required to harness/measure non-linear surface motions. Therefore, a feasible, cost-effective and less-time consuming groove technique was developed to fabricate adaptable HS-FPCSs with multiple lengths. A single HS-CSPNG generates 130 V/0.8 μA and can also work as a self-powered muscle monitoring system (SP-MMS) to measure maximum human body part movements, i...

BACKGROUND: When compared to systemic administration, if used correctly inhalers deliver a smaller enough percent of the drug right to the site of action in the lungs, with a faster onset of effect and with reduced systemic availability that minimizes adverse effects. However, the health professionals' and patients' use of metered dose inhaler is poor. OBJECTIVE: This study was aimed to explore community pharmacy professionals' (pharmacists' and druggists') competency on metered dose inhaler (MDI) technique...

We inhale respiratory pathogens continuously, and the subsequent signaling events between host and microbe are complex, ultimately resulting in clearance of the microbe, stable colonization of the host, or active disease. Traditional in vitro methods are ill-equipped to study these critical events in the context of the lung microenvironment. Here we introduce a microscale organotypic model of the human bronchiole for studying pulmonary infection. By leveraging microscale techniques, the model is designed to approximate the structure of the human bronchiole, containing airway, vascular, and extracellular matrix compartments...

PURPOSE: Lung diseases are commonly associated with changes in lung tissue's biomechanical properties. Functional imaging techniques, such as elastography, have shown great promise in measuring tissue's biomechanical properties, which could expand the utility and effectiveness of radiotherapy treatment planning. We present a novel methodology for characterizing a key biomechanical property, parenchymal elasticity, derived solely from 4DCT datasets. METHODS: Specifically, end-inhalation and end-exhalation breathing phases of the 4DCT datasets were deformably registered and the resulting displacement maps were considered to be ground-truth...

The introduction of 16s ribosomal RNA sequencing as a nonculture technique has led to the discovery of the presence of microbiota in the lower airways of healthy individuals. These bacterial communities may originate from the mouth and nasopharynx or from the environment by inhalation. The microbial composition of the lower airways may be modulated by dietary factors, antibiotic therapy, and microbial infections, particularly in early life. In addition, circulatory products from gut microbiota may influence the lung microbiota to maintain mucosal immunity...
