Use of cannabidiol in anxiety and anxiety-related disorders.

Objective: Cannabidiol (CBD) has a proposed novel role in the management of anxiety owing to its actions on the endocannabinoid system. The purpose of this systematic review was to evaluate the current evidence on the safety and efficacy of CBD in anxiety and anxiety-related disorders.

Data Sources: A literature search was conducted on PubMed, Google Scholar, and International Pharmaceutical Abstracts from database inception through June 2019.

Facilitators and Barriers to Noninvasive Ventilation Adherence in Youth with Nocturnal Hypoventilation Secondary to Obesity or Neuromuscular Disease.

Objective: Many youth struggle with adherence to bilevel noninvasive ventilation (NIV), often shortly after initiation of treatment. Anecdotal evidence suggests youths with comorbid obesity struggle with adherence while youths with comorbid neuromuscular disease demonstrate better adherence rates. The objective of this study was to explore factors relating to bilevel NIV adherence, and to compare these between youths with underlying obesity or neuromuscular disease.

Electroacoustic and Potentiometric Studies of the Hematite/Water Interface.

The basic charging properties of nearly spherical hematite particles were studied by using potentiometric titration and the electroacoustic technique. Both the pH and the ionic strength dependence of the surface charge and the zeta-potential were studied in detail. For calculating the zeta-potential from mobility data a few different theories were used and obtained differences are discussed.
