Strategies for Nonpolar Aerosol Collection and Heavy Metals Analysis of Inhaled Cannabis Products.

ACS Omega 2021 Jul 21;6(26):17126-17135. Epub 2021 Jun 21.

Medicine Creek Analytics, 3700 Pacific Highway East, Fife, Washington 98424, United States.

The rapid growth of inhalable cannabis concentrates raises questions about the safety of acute and chronic exposure to these aerosol mixtures. Due to the nonpolar nature of the aerosol mixture created from cannabis vapor cartridges, traditional aqueous-based capture methods used in e-cigarette or tobacco cigarette studies for analysis of metals are insufficient. Moreover, hydrophobic cannabis concentrates are not miscible with dilute aqueous acids and therefore not ideal for metal spiking unlike electronic nicotine delivery systems. Read More

Comparative Study of Clinical and Ultrasound Parameters for Defining a Difficult Airway in Patients with Obesity.

Obes Surg 2021 Sep 5;31(9):4118-4124. Epub 2021 Jul 5.

São Domingos Hospital, São Luís, Brazil.

Introduction: Patients with obesity have anatomical changes due to increased adipose tissue that negatively affect airway accessibility, making it difficult to establish an advanced airway through orotracheal intubation. This article aims to evaluate the correlation of clinical and sonographic parameters as predictors of difficult airway management (DAM) in patients with obesity and to establish the predictive value of the skin-epiglottis distance as an indicator of a probable DAM.
