This study assessed the hand hygiene performance in French nursing homes using the consumption of alcohol-based hand rubs (AHRs) as a surrogate. Nursing homes from the 17 French regions were contacted to collect their AHR consumption and occupancy in 2018 and 2019. A total of 1290 nursing homes from 15 French regions participated in the survey. The estimated median number of hand hygiene actions per resident-day was 1.48 (interquartile range: 1.04-2.03) in 2018 and 1.60 (1.10-2.26) in 2019. A significantly higher AHR consumption was observed in public nursing homes with an infection control team or link nurse.

Anaphylactic reactions to ethanol are rare with only seven cases reported in the literature. All previous cases have occurred following ingestion of alcoholic beverages or food to which an alcoholic beverage has been added. To date there are no cases in the literature of ethanol-induced anaphylaxis caused by the accumulation of endogenous ethanol in overripe fruit.We report a patient with ethanol-induced anaphylaxis who developed anaphylaxis following ingestion of overripe, but not fresh rock melon (Cucumis melo). The patient is a 24-year-old, previously well woman who experienced five episodes of acute anaphylaxis following ingestion of various alcoholic beverages and, on one occasion, following ingestion of overripe rock melon to which no ethanol was added. Ethanol-induced anaphylaxis was confirmed on blinded challenge; however, challenge with freshly prepared rock melon was negative. The patient declined further challenges.Ingestion of overripe fruits may cause anaphylaxis in patients with ethanol-induced anaphylaxis. These patients should therefore, be advised to avoid ingestion of overripe fruits.

Abstract In order to achieve a perfect bottom-up electroplated Cu filling with a minimal surface thickness, 2-mercaptopyridine (2-MP) was investigated as a new leveler for replacing Janus Green B (JGB) for bottom-up copper filling. Electrochemical impedence results indicate that 2-MP has a stronger suppression for Cu deposition than JGB. With the addition of 2-MP, the filling capability of the electroplating solution is improved significantly with the Cu thickness on surface decreasing from ∼16 μm to ∼10 μm. The interaction mechanisms of 2-MP, bis(3-sulfopropyl) disulfide (SPS), Cl − and tri-block copolymer of PEG and PPG with ethylene oxide terminal blocks (EPE) in the plating solution are studied by galvanostatic measurements (GMs). The acceleration effect of SPS and the inhibition effect of 2-MP on copper deposition occur in the presence of EPE, and the convection-dependent adsorption (CDA) behavior of additives usually occurs with the injection of four additives at optional concentrations. Further, it was found that when 1.0 ppm 2-MP, 1.0 ppm SPS and 200 ppm EPE were injected into the basic electrolyte, the potential difference ( Δ h) value of the electrolyte became positive, and the bottom-up electroplated copper filling was obtained in the electrolyte in absence of Cl − . The interaction mechanisms of three additives for bottom-up filling have been investigated by GMs.

Abstract: Five groups of NMRI mice were fed ethanol or sucrose in a nutritionally adequate liquid diet for 9 days. The dietary fat consisted of olive oil with the fatty acid composition 18:1 77%, 18:2 10%, 18:0 and 16:0 12%. The ethanol treated groups received 5% w/v ethanol (E) or isocaloric sucrose (S). Two groups (S‐ and E‐) received the diet without supplement. In two groups (S+ and E +) 7% of the fat was exchanged for arachidonic acid (20:4). In a fifth group (IE +) treated with ethanol and arachidonic acid the diet also contained indomethacin (10 mg/1). The mean intake of ethanol was about 20 g/kg/day. After 9 days animals were killed and liver lipids analyzed after Folch extraction. The post mortem accumulation of prostaglandin E2 in the kidney was measured by GC‐MS. Dietary 20:4 was found to protect mice against fatty liver caused both by a high fat diet alone and in combination with ethanol. The liver triglycerides were 30.7 + 4.3 (S ‐), 46.1+6.9 (E ‐), 6.8 + 0.4 (S +) and 19.4 ±1.8 (E +). Prostaglandin levels in the kidney were depressed by ethanol treatment. Indomethacin gave variable degrees of PG synthesis inhibition. The degree of liver triglyceride accumulation in the IE+ group was inversely propotional to the degree of PG synthesis. The data suggest a role for liver 20:4 cyclooxyganase metabolites in fatty liver caused by high fat diets and ethanol.

In the current era, the importance of proper hand hygiene to reduce the transmission of infectious diseases has become difficult to debate. Yet, compliance rates remain low and are affected by many factors, amongst which is user acceptability of hand hygiene products.The present study aimed at investigating drivers of preference towards different hand hygiene formulations.Three different formulations (liquid, foam and gel) of the same brand were randomly and blindly evaluated by 54 participants based on the WHO Protocol for Evaluation of Tolerability and Acceptability of Alcohol-based Handrubs.The majority (76%) of respondents indicated that the product formulation impacted their level of compliance with hand hygiene protocols. The preferred formulation was liquid, with 50% of participants ranking it as first choice. General product satisfaction, the product texture, the drying speed and the ease of application, were the statistically significant drivers for participants to rank a formulation as their first choice vs not ranking it as their first choice.When designing alcohol formulations and implementing hand hygiene protocols, understanding drivers of preference for formulations may enhance product user acceptability and therefore compliance with hand hygiene.

The accuracy and reliability of a rapid blood alcohol estimation by means of a breath alcohol analyser has been evaluated under casualty department conditions in a series of 646 road-crash victims managed at the Dandenong and District Hospital. A higher correlation (r = 0.91) was found between the breath alcohol analyser readings in 633 casualties and those obtained by blood analysis in the police laboratory. In 13 unconscious casualties in whom a nasal breath test was performed, the correlation was lower (r = 0.76). In six casualties, the breath alcohol analyser readings showed lower alcohol concentrations than the legal limit of 0.05 g/100 mL (10.9 mmol/L), but blood analysis detected an illegal concentration. Further evaluation of the accuracy of the breath alcohol analyser in other casualty departments is necessary before it can be recommended as a screening device in States which have legislated for compulsory blood alcohol tests in adult road casualties.

The use of ionic liquid (IL) electrolytes promises to improve the energy density of electrochemical capacitors (ECs) by allowing for operation at higher voltages. Several studies have also shown that the pore size distribution of materials used to produce electrodes is an important factor in determining EC performance. In this research the capacitative, energy and power performance of ILs 1-ethyl-3-methylimidazolium tetrafluoroborate (EMImBF4), 1-ethyl-3-methylimidazolium dicyanamide (EMImN(CN)2), 1,2-dimethyl-3-propylimidazolium bis(trifluoromethylsulfonyl)imide (DMPImTFSI), and 1-butyl-3-methylpyrrolidinium tris(pentafluoroethyl)trifluorophosphate (BMPyT(F5Et)PF3) were studied and compared with the commercially utilised organic electrolyte 1 M tetraethylammonium tetrafluoroborate solution in anhydrous propylene carbonate (Et4NBF4–PC 1 M). To assess the effect of pore size on IL performance, controlled porosity carbons were produced from phenolic resins activated in CO2. The carbon samples were characterised by nitrogen adsorption–desorption at 77 K and the relevant electrochemical behaviour was characterised by cyclic voltammetry, galvanostatic charge–discharge and electrochemical impedance spectroscopy. The best capacitance performance was obtained for the activated carbon xerogel with average pore diameter 3.5 nm, whereas the optimum rate performance was obtained for the activated carbon xerogel with average pore diameter 6 nm. When combined in an EC with IL electrolyte EMImBF4 a specific capacitance of 210 F g−1 was obtained for activated carbon sample with average pore diameter 3.5 nm at an operating voltage of 3 V. The activated carbon sample with average pore diameter 6 nm allowed for maximum capacitance retention of approximately 70% at 64 mA cm−2.

Self-poisoning in children is a serious health concern accounting for 2% and 5% of childhood deaths in the developed and developing world, respectively. Type of poison and intent varies between age groups, with alcohol poisoning becoming increasingly common in teenagers. The aim of the study was to identify the characteristics of paediatric self-poisoning at Ninewells Hospital, Dundee, as a function of age, sex, intent and type of poison. Data from patients under the age of 17 presenting to Ninewells Hospital's Emergency Department with self-poisoning from 1 December 2008 to 30 November 2009 inclusive were identified, classified and analysed using chi-square testing. Overall there was no significant difference in gender. However, females significantly dominated in the ≥12<17 years age group, with older females also significantly more likely to deliberately self-poison. Alcohol was the sole cause of accidental self-poisoning in this age group while paracetamol was used in the majority of cases of deliberate self-poisoning. In the <6 years age group, household chemical ingestion and over-the-counter medications were the most common poisons. The findings reflect previous published data and national trends. The prevalence of alcohol abuse in the ≥12<17 years age group is a major public health issue that must be addressed.
