Risk factors of local oropharyngeal and laryngeal adverse effects from use of single inhaled corticosteroids and long-acting beta-agonists.

Background: Single inhaled corticosteroids and long-acting beta-agonists (ICS/LABA) are clinically effective and safe. However, if local oropharyngeal and laryngeal adverse effects (LOLAE) appear, adherence to the use of ICS is impaired. To minimize the development of adverse effects, it is essential to identify the underlying risk factors.

Metal ion-selective membrane prepared by surface molecular imprinting.

Surface molecular imprinting was applied to the preparation of an ion-selective polymeric membrane for the first time. The use of acrylonitrile-butadiene rubber and a porous solid support in the polymer matrix resulted in improved flexibility and mechanical strength of the imprinted membrane. The asymmetric porous structure of the membrane was observed by scanning electron microscopy.
