Background: Asthma and chronic obstructive pulmonary disease (COPD) are widespread chronic conditions with medication frequently delivered by inhalers. These can be challenging to use correctly, but the scale of misuse and the specific aspects of failure are unclear.

Methods: We used systematic review methods to search 9 databases in May 2015 to identify and review studies that assessed adults (18 years or older) with asthma or COPD using inhalers of various types including pressurised metered dose inhalers (pMDIs), dry powder inhalers and the Respimat inhaler.

Background: Fixed-dose combinations of inhaled corticosteroids and long-acting β agonists are commonly used for the treatment of asthma and COPD. However, the most frequently prescribed dry powder inhaler delivering this medicine - Symbicort (budesonide and formoterol, BF) Turbuhaler - is associated with poor inhalation technique, which can lead to poor disease control and high disease management costs. A recent study showed that patients make fewer inhaler errors when using the novel DuoResp (BF) Spiromax inhaler, compared with BF Turbuhaler.

Background: Asthma and chronic obstructive pulmonary disease (COPD) are common chronic inflammatory respiratory diseases, which impose a substantial burden on healthcare systems and society. Fixed-dose combinations (FDCs) of inhaled corticosteroids (ICS) and long-acting β2 agonists (LABA), often administered using dry powder inhalers (DPIs), are frequently prescribed to control persistent asthma and COPD. Use of DPIs has been associated with poor inhalation technique, which can lead to increased healthcare resource use and costs.

The effective self-management of obstructive lung disease is dependent upon the patient achieving good inhaler technique. However, many current inhalers are complicated to use, which may lead to handling difficulties. These difficulties can cause clinically relevant errors, whereby pharmacotherapy fails to achieve adequate lung deposition and therapeutic effect.

Objective: The relation between lipid accumulation and influence of exercise on insulin sensitivity is not straightforward. A proper balance between lipid droplet synthesis, lipolysis, and oxidative metabolism would ensure low local intramyocellular fatty acid levels, thereby possibly protecting against lipotoxicity-associated insulin resistance. This study investigated whether the accumulation of triglycerides and lipid droplets in response to high availability of fatty acids after high-fat feeding would parallel the abundance of intramyocellular perilipin proteins, especially PLIN5.

Social information transmission is important because it enables horizontal spread of behaviors, not only between conspecifics but also between individuals of different species. Because interspecific social information use is expected to take place among species with similar resource needs, it may have major consequences for the emergence of local adaptations, resource sharing, and community organization. Social information use is expected to be selective, but the conditions promoting it in an interspecific context are not well known.
