The inter-play between facilitation and context in the promoting action on research implementation in health services framework: A qualitative exploratory implementation study embedded in a cluster randomized controlled trial to reduce restraint in nursing homes.

Aim: To explore the inter-play between external facilitation and nursing home contexts relative to intervention outcomes.

Background: The Promoting Action on Research Implementation in Health Services framework is frequently used to theoretically inform implementation and research in nursing and recent reviews indicate high face validity for health services. However, the inter-play and relationship between framework sub-elements of evidence, context and facilitation and the prospective utility in non-English speaking contexts warrant further illumination.

Urinary ethyl glucuronide and ethyl sulfate testing for recent drinking in alcohol-dependent outpatients treated with acamprosate or placebo.

Aims: Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are sensitive and specific biomarkers for recent alcohol ingestion. This study compared urinary EtG and EtS measurement with self-reports for detection of prior drinking in alcohol-dependent outpatients treated with the anti-craving medication acamprosate or placebo.

Methods: Alcohol-dependent outpatients (26 women, 30 men) were randomized to 21 days of oral acamprosate (2 g/day) or placebo treatment in a double-blind design.

Urinary ethyl glucuronide and ethyl sulfate testing for detection of recent drinking in an outpatient treatment program for alcohol and drug dependence.

Aims: This study determined the information about recent alcohol consumption obtained when urinary ethyl glucuronide (EtG) and ethyl sulfate (EtS) were introduced as a routine test in outpatient treatment programs for alcohol and drug dependence.

Patients And Methods: Outpatients (21 men and 3 women) undergoing treatment for alcohol (N = 8) or drug (N = 10) dependence, or in methadone maintenance therapy (N = 6) volunteered for the study. Twice weekly in connection with return visits to the unit, patients gave a urine sample and completed an anonymous single-question form about any drinking in the past 3 days.

Value of ethyl glucuronide in plasma as a biomarker for recent alcohol consumption in the emergency room.

Aim: This emergency department (ED) study compared the value of plasma ethyl glucuronide (EtG) testing with the information about alcohol consumption obtained using the standard alcohol biomarkers gamma-glutamyltransferase (GGT) and carbohydrate-deficient transferring (CDT) and the AUDIT questionnaire.

Methods: Minimally injured and clinically non-intoxicated male patients (n = 81) admitted to an ED were screened regarding their alcohol consumption, using the computerized AUDIT questionnaire and a paper-and-pencil assessment including the type, amount and time of alcohol intake. Blood samples were collected for determination of ethanol, EtG (LC-MS) and GGT in plasma and %CDT in serum (Axis-Shield %CDT immunoassay).

Postcollection synthesis of ethyl glucuronide by bacteria in urine may cause false identification of alcohol consumption.

Background: Ethyl glucuronide (EtG) is a minor ethanol metabolite used as a specific marker to document recent alcohol consumption; confirm abstinence in treatment programs, workplaces, and schools; and provide legal proof of drinking. This study examined if bacterial pathogens in urine may enable postsampling synthesis of EtG and ethyl sulfate (EtS) from ethanol, leading to clinical false-positive results.

Methods: Urine specimens with confirmed growth of Escherichia coli, Klebsiella pneumoniae, or Enterobacter cloacae were stored at room temperature in the presence of ethanol.

Determination of urinary 5-hydroxytryptophol glucuronide by liquid chromatography-mass spectrometry.

5-Hydroxytryptophol glucuronide (GTOL) is the major excretion form of 5-hydroxytryptophol (5-HTOL), a minor serotonin metabolite under normal conditions. Because the concentration of 5-HTOL is markedly increased following consumption of alcohol, measurement of 5-HTOL is used as a sensitive biomarker for detection of recent alcohol intake. This study describes the development and evaluation of a liquid chromatography-electrospray ionization mass spectrometry (LC-MS) procedure for direct quantification of GTOL in human urine.

Urinary ethyl glucuronide and 5-hydroxytryptophol levels during repeated ethanol ingestion in healthy human subjects.

Aims: This study investigated the stability and reproducibility of urinary ethyl glucuronide (EtG) and the 5-hydroxytryptophol (5-HTOL) to 5-hydroxyindole-3-acetic acid (5-HIAA) ratio, both of which are used as biochemical markers of recent alcohol consumption, after single and multiple oral doses of ethanol in healthy human subjects.

Methods: Nine females aged 19-27 years drank ethanol (8%, w/v, in juice) or placebo (juice) in random order. The intervention consisted of 0.

Direct quantification of ethyl glucuronide in clinical urine samples by liquid chromatography-mass spectrometry.

Ethyl glucuronide is a minor metabolite of ethanol, and its presence in urine can be used as a laboratory test to detect recent alcohol intake, even for some time after the ethanol is no longer measurable. A simple analytical procedure was developed based on direct injection of urine diluted with a deuterated internal standard into an electrospray liquid chromatographic-mass spectrometric (LC-MS) system. A novel LC system using a porous graphite column (Hypercarb) enabled an isocratic elution with retention times of 5-6 minutes.

Comparison of urinary excretion characteristics of ethanol and ethyl glucuronide.

This study compared the urinary excretion characteristics of ethyl glucuronide (EtG) with that of ethanol, with focus on the effect of water-induced diuresis. Six healthy volunteers ingested an ethanol dose of 0.5 g/kg (range 25.
