There is a public health epidemic in adolescents' use of Electronic Nicotine Delivery Systems (ENDSs), also known as electronic cigarettes, vaping products, or JUULs. However, little is known about the level of knowledge school staff have about ENDS. The purpose of this study is to examine outcomes of a nurse-led educational intervention designed to increase school staff knowledge about ENDS. A descriptive, nonrandomly selected pre-test/post-test design was used with 125 Wisconsin school staff. Results revealed further educational needs of school staff in content areas including advertising to youth and flavoring of ENDS. Following the educational intervention, post-test results showed a significant overall improvement in participant knowledge scores. Recommendations include implementing nurse-led education about ENDS to a more diverse population of school staff. Providing nurse-led ENDS education to school staff offers an upstream, proactive approach for school nurses to help address this public health epidemic. [ABSTRACT FROM AUTHOR]

The article discusses the benefits of salivary duct endoscopy, or sialendoscopy, in treating obstructive salivary gland disease when compared to other methods such as sonography, magnetic resonance imaging (MRI) or computed tomography (CT). It says that sialendoscopy allows surgeons to visualize the ductal system that enables a definite diagnosis of the disease. It adds that the benefits of the procedure can be seen particularly in its therapeutic benefits such as the removal of ductal stones and dilation of stenotic ducts to wash away debris.

It has been suggested that magnesium deficiency is correlated with many diseases. 31P NMR experiments were carried out in order to investigate the effects of Na+ substitution on Mg2+ depletion in smooth muscle under divalent cation-free conditions. In the taenia of guinea-pig caeci, the intracellular free Mg2+ concentration ([Mg2+]i) was estimated from the chemical shifts of (1) the beta-ATP peak alone and (2) beta- and gamma-ATP peaks. Both estimations indicated that [Mg2+]i decreased only very slowly in Mg(2+)-free, Ca(2+)-free solutions in which Na+ was substituted with large cations such as NMDG (N-methyl-D-glucamine) and choline. Furthermore, the measurements of tension development supported the suggestion of preservation of intracellular Mg2+ with NMDG substitution. Substituting extracellular Na+ with the small cation, Li+, also shifted the beta-ATP peak towards a lower frequency, but the frequency shift was significantly less than that seen upon Na+ substitution with K+. The estimated [Mg2+]i depletion was, however, comparable with that seen after Na+ substitution with K+ using the titration curves of metal-free and Mg(2+)-bound ATP obtained in Li(+)-based model solutions. It was concluded that Mg2+ rapidly decreases only when small cations were the major electrolyte of the extracellular medium. Na+ substitutions with NMDG, choline or Li+ had little effect on intracellular ATP concentration after 100 min treatment.
