Association Between Quality of Cheap and Unrecorded Alcohol Products and Public Health Consequences in Poland

ALCOHOLISM, Issue 10 2009
Dirk W. Lachenmeier
Background:, The research aimed to study the quality of cheap alcohol products in Poland. These included unrecorded alcohols (i.e., home-produced or illegally imported), estimated to constitute more than 25% of total consumption and fruit wines. Methods:, A sample of alcohol products (n = 52) was collected from local markets and chemical analyses were conducted. The parameters studied were alcoholic strength, volatiles (methanol, acetaldehyde, and higher alcohols), ethyl carbamate, inorganic elements, and food additives including preservatives, colors, and sweeteners. The compositions of the beverages were then toxicologically evaluated using international standards. Results:, With the exception of 1 fortified wine, the unrecorded alcohols were home-produced fruit-derived spirits (moonshine) and spirits imported from other countries. We did not detect any nonbeverage surrogate alcohol. The unrecorded spirits contained, on average, 45% vol of alcohol. However, some products with considerably higher alcoholic strengths were found (up to 85% vol) with no labeling of the content on the bottles. These products may cause more pronounced detrimental health effects (e.g., liver cirrhosis, injuries, some forms of malignant neoplasms, alcohol use disorders, and cardiovascular disease) than will commercial beverages, especially as the consumer may be unaware of the alcohol content consumed. Fruit wines containing between 9.5 and 12.2% vol alcohol showed problems in terms of their additive content and their labeling (e.g., sulfites, sorbic acid, saccharin, and artificial colors) and should be subjected to stricter control. Regarding the other components investigated, the suspected human carcinogens, acetaldehyde and ethyl carbamate, were found at levels relevant to public health concerns. While acetaldehyde is a typical constituent of fermented beverages, ethyl carbamate was found only in home-produced unrecorded alcohols derived from stone fruits with levels significantly above international guidelines. Conclusions:, The contamination of unrecorded alcohols with ethyl carbamate should be analyzed in a larger sample that also should include legal alcoholic beverages. Furthermore, the impacts of unrecorded alcohol on the health of people with lower socioeconomic status should be studied in detail. Overall, given the extent of the alcohol-attributable disease burden in Poland, the highest priority should be given to the problem of ethanol and its very high content in unrecorded alcohol products.

Impact of Wearable Alcohol Gel Dispensers on Hand Hygiene in an Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 4 2008
Janet P. Haas RN
Abstract Objectives:, Compliance with hand hygiene (HH) by health care workers is widely recognized as the most effective way to decrease transmission of infection among patients. However, compliance remains poor, averaging about 40%. A potential barrier to compliance is convenience and accessibility of sinks or alcohol hand sanitizer dispensers. The purpose of this study was to assess the use of a personal alcohol gel dispensing system, compared with the traditional wall-mounted alcohol gel dispenser and sinks in an urban hospital's emergency department (ED). Methods:, This was a quasi-experimental trial of a personal wearable alcohol hand sanitizer dispenser. Observations of ED staff HH were performed in the month before intervention and during three intervention phases over a 2.5-month period. Results:, A total of 757 HH opportunities were observed: 112 before and 432 after patient contact, 72 after contact with the patient's environment, 24 before invasive procedures, and 117 after body fluid contact. HH compliance improved during the first intervention period, but improvement was not sustained. There was no significant improvement in HH from baseline to the final intervention period. The wearable alcohol gel dispenser was used for 9% of HH episodes. Conclusions:, Availability of a wearable dispenser was not associated with a significant improvement in use of alcohol products for HH. These results support other studies in which only transient success was reported with a single intervention; greater success in sustaining increased HH compliance has been reported with use of multimodal approaches in which increased availability of products may be a part of the intervention.

Highly Enantioselective Ruthenium-Catalyzed Reduction of Ketones Employing Readily Available Peptide Ligands

CHEMISTRY - A EUROPEAN JOURNAL, Issue 1 2004
Anders Bøgevig Dr.
Abstract Highly efficient and selective catalysts for the asymmetric reduction of aryl alkyl ketones under hydrogen-transfer conditions (2-propanol) were obtained by combining a novel class of pseudo-dipeptide ligands with [{RuCl2(p- cymene)}2]. A library of 36 dipeptide-like ligands was prepared from N -Boc-protected ,-amino acids and the enantiomers of 2-amino-1-phenylethanol and 1-amino-2-propanol. The catalyst library was evaluated with the reduction of acetophenone and excellent enantioselectivity of 1-phenylethanol was obtained with several of the novel catalysts. A ligand based on the combination of N -Boc- L -alanine and (S)-1-amino-2-propanol (ligand A - (S)- 4) was found to be particular effective. When the situ formed ruthenium complex of this ligand was employed as the catalyst in the hydrogen-transfer reaction of various aryl alkyl ketones, the corresponding alcohol products were achieved in excellent enantioselectivity (up to 98,% ee).
