TBI as a Risk Factor for Substance Use Behaviors: A Meta-analysis.

Objective: To quantify the relationship between substance use behaviors before and after traumatic brain injury (TBI), to identify populations that may benefit more from targeted interventions to reduce the effect of substance use on TBI recovery, and to establish areas for further study.

Data Sources: Studies were identified via literature searches using MEDLINE, PsychInfo, PsychArticles, PubMed, and GoogleScholar (published before January 2019), as well as reference section reviews and forward searches. Searches were conducted using search terms for TBI and substance use behaviors.

Diamines as switchable-hydrophilicity solvents with improved phase behaviour.

Removing solvents by distillation is not a sustainable process because it requires the use of volatile solvents and a high energy input. An alternative is to use a switchable-hydrophilicity solvent (SHS), which can be removed from products and recycled without any distillation step. SHSs are solvents that reversibly switch between hydrophilic and hydrophobic forms with the addition and removal of a trigger such as CO.

Characterizing the Effects of a "Switchable Water" Additive on the Aqueous Solubility of Small Molecules.

"Switchable water" is an aqueous solution containing a water-soluble amine additive that exhibits CO -switchable properties, such as large changes in ionic strength, by forming an ammonium bicarbonate salt. Switchable water has been used to reversibly "salt-out" organic compounds from water. This study explores the salting out of several compounds in switchable water when CO is present and also explores the solubility of small molecules in switchable water, compared to pure water, when CO is absent.

Characteristics and clinical treatment of tobacco smokers enrolled in a VA substance use disorders clinic.

Individuals with a substance use disorder (SUD) diagnosis are more than twice as likely to smoke cigarettes as the general population. Emerging research has suggested that treating a substance use disorder simultaneously with tobacco use leads to a higher rate of treatment success for both substances. Despite this, substance use treatment protocols tend not to focus on tobacco use; in fact, traditional substance use treatments often discourage patients from attempting to quit smoking.

Beliefs About the Direct Comparison of E-Cigarettes and Cigarettes.

Background: Recent data suggests that positive beliefs about electronic cigarettes (e-cigs) use can lead to later e-cig use. Considering that many advertisements claim that e-cigs are superior to cigarettes, individuals' likelihood to view e-cigs more favorably than cigarettes can also influence subsequent e-cig use; however, no studies have directly assessed such a comparison.

Objectives: The present study created and validated the Comparing E-Cigarettes and Cigarettes questionnaire (CEAC), which asks individuals to directly compare e-cigs and cigarettes on a number of dimensions, in two independent samples.
