Objective:
The aim of this study was to determine the sensitivity and specificity of potential thresholds of alcohol use for identifying alcohol-related problems in women post-Roux-en-Y gastric bypass (RYGB).
Background:
Despite evidence that RYGB alters alcohol pharmacokinetics and is associated with an increased risk for alcohol-related problems, the level of alcohol use that should prompt further screening for alcohol-related problems following RYGB is unclear.
Methods:
The Longitudinal Assessment of Bariatric Surgery-2 is a prospective cohort study. Before surgery and annually for ≤7 years following surgery, participants completed the 10-item Alcohol Use Disorder Identification Test (AUDIT), which assesses past-year frequency and quantity of alcohol, frequency of consuming ≥6 drinks, and alcohol-related problems (ie, symptoms of alcohol dependence and/or alcohol-related harm). The AUDIT-Consumption (AUDIT-C) score was determined from the first 3 AUDIT items.
Results:
Post-RYGB, 835 women reported current drinking at 1 or more annual assessment(s). Compared with higher frequency thresholds, drinking ≥2 times/month had the highest combined sensitivity (85.3%) and specificity (61.4%) for identifying alcohol-related problems. Compared with higher quantity thresholds, drinking ≥3 drinks/drinking day had the highest combined sensitivity (64.2%) and specificity (87.2%). An AUDIT-C score ≥3, versus other thresholds, had the highest combined sensitivity (76.4%) and specificity (81.6%).
Conclusion:
The sensitivity and specificity of these thresholds indicate assessment of alcohol consumption alone may be inadequate for identifying women at risk for alcohol-related problems post-RYGB. Additional screening tools for alcohol-related problems, which assess symptoms of alcohol-related problems, should be conducted in this population.

02:37Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
02:31Protection of Alcohols
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
01:38Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
01:17Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...
01:08Esters to Alcohols: Grignard Reaction
The reaction requires two equivalents of the Grignard reagent and introduces two identical alkyl groups, derived from the Grignard reagent, bonded to the hydroxyl-bearing carbon of the alcohol.
The reaction follows the typical nucleophilic acyl substitution mechanism. The Grignard...
