A test of interaction effects between alcohol protective behavioral strategies and antecedents of alcohol-related consequences

The purpose of the present study was to examine interaction effects between alcohol protective behavioral strategies (PBS) and a variety of risk and protective factors for experiencing negative alcohol-related consequences using data from a large, multi-site sample of college students. We recruited 5090 college students (71.2% female; 77.4% White; Mean Age = 20.89, SD = 4.44) who reported any alcohol use in the past month from psychology department participant pools at 10 universities across the U.S. to complete an online survey. Alcohol PBS use was a statistically significant negative predictor of alcohol-related problems while controlling for each antecedent variable individually. In terms of moderation effects, 26 out of 35 interactions (74.3%) were statistically significant in the models controlling only for sex. When controlling for frequency and quantity of alcohol use, 24 of 33 interactions (72.7%) were statistically significant. The nature of these interaction effects was largely the same: more frequent alcohol PBS use reduced the positive associations between risk factors and alcohol-related problems. The lack of specificity of these interaction effects calls into question the limited contributions of tests of interaction effects between alcohol PBS and individual antecedent variables. Comprehensive tests of interaction effects between alcohol PBS and antecedent variables with large samples are needed to move the field forward, especially replication attempts of interactions effects reported in single studies.

A Randomized Trial of Albumin Infusions in Hospitalized Patients with Cirrhosis

BACKGROUND Infection and increased systemic inflammation cause organ dysfunction and death in patients with decompensated cirrhosis. Preclinical studies provide support for an antiinflammatory role of albumin, but confirmatory large-scale clinical trials are lacking. Whether targeting a serum albumin level of 30 g per liter or greater in these patients with repeated daily infusions of 20% human albumin solution, as compared with standard care, would reduce the incidences of infection, kidney dysfunction, and death is unknown. METHODS We conducted a randomized, multicenter, open-label, parallel-group trial involving hospitalized patients with decompensated cirrhosis who had a serum albumin level of less than 30 g per liter at enrollment. Patients were randomly assigned to receive either targeted 20% human albumin solution for up to 14 days or until discharge, whichever came first, or standard care. Treatment commenced within 3 days after admission. The composite primary end point was new infection, kidney dysfunction, or death between days 3 and 15 after the initiation of treatment. RESULTS A total of 777 patients underwent randomization, and alcohol was reported to be a cause of cirrhosis in most of these patients. A median total infusion of albumin of 200 g (interquartile range, 140 to 280) per patient was administered to the targeted albumin group (increasing the albumin level to =30 g per liter), as compared with a median of 20 g (interquartile range, 0 to 120) per patient administered to the standard-care group (adjusted mean difference, 143 g; 95% confidence interval [CI], 127 to 158.2). The percentage of patients with a primary end-point event did not differ significantly between the targeted albumin group (113 of 380 patients [29.7%]) and the standard-care group (120 of 397 patients [30.2%]) (adjusted odds ratio, 0.98; 95% CI, 0.71 to 1.33; P = 0.87). A time-to-event analysis in which data were censored at the time of discharge or at day 15 also showed no significant between-group difference (hazard ratio, 1.04; 95% CI, 0.81 to 1.35). More severe or life-threatening serious adverse events occurred in the albumin group than in the standard-care group. CONCLUSIONS In patients hospitalized with decompensated cirrhosis, albumin infusions to increase the albumin level to a target of 30 g per liter or more was not more beneficial than the current standard care in the United Kingdom.

Assessment of Annual Cost of Substance Use Disorder in US Hospitals

IMPORTANCE A persistently high US drug overdose death toll and increasing health care use associated with substance use disorder (SUD) create urgency for comprehensive estimates of attributable direct costs, which can assist in identifying cost-effective ways to prevent SUD and help people to receive effective treatment. OBJECTIVE To estimate the annual attributable medical cost of SUD in US hospitals from the health care payer perspective. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation of observational data used multivariable regression analysis and mathematical modeling of hospital encounter costs, controlling for patient demographic, clinical, and insurance characteristics, and compared encounters with and without secondary SUD diagnosis to statistically identify the total attributable cost of SUD. Nationally representative hospital emergency department (ED) and inpatient encounters from the 2017 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample and National Inpatient Sample were studied. Statistical analysis was performed from March to June 2020. EXPOSURES International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) principal or secondary SUD diagnosis on the hospital discharge record according to the Clinical Classifications Software categories (disorders related to alcohol, cannabis, hallucinogens, inhalants, opioids, sedatives, stimulants, and other substances). MAIN OUTCOMES AND MEASURES Annual attributable SUD medical cost in hospitals overall and by substance type (eg, alcohol). The number of encounters (ED and inpatient) with SUD diagnosis (principal or secondary) and the mean cost attributable to SUD per encounter by substance type are also reported. RESULTS This study examined a total of 124 573 175 hospital ED encounters and 33 648 910 hospital inpatient encounters from the 2017 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample and National Inpatient Sample. Total annual estimated attributable SUD medical cost in hospitals was $13.2 billion. By substance type, the cost ranged from $4 million for inhalantrelated disorders to $7.6 billion for alcohol-related disorders. CONCLUSIONS AND RELEVANCE This study’s results suggest that the cost of effective prevention and treatment may be substantially offset by a reduction in the high direct medical cost of SUD hospital care. The findings of this study may inform the treatment of patients with SUD during hospitalization, which presents a critical opportunity to engage patients who are at high risk for overdose. Aligning incentives such that prevention cost savings accrue to payers and practitioners that are otherwise responsible for SUD-related medical costs in hospitals and other health care settings may encourage prevention investment.

Renewable biohydrogen production from lignocellulosic biomass using fermentation and integration of systems with other energy generation technologies

Biohydrogen is a clean and renewable source of energy. It can be produced by using technologies such as thermo-chemical, electrolysis, photoelectrochemical and biological, etc. Among these technologies, the biological method (dark fermentation) is considered more sustainable and ecofriendly. Dark fermentation involves anaerobic microbes which degrade carbohydrate rich substrate and produce hydrogen. Lignocellulosic biomass is an abundantly available raw material and can be utilized as an economic and renewable substrate for biohydrogen production. Although there are many hurdles, continuous advancements in lignocellulosic biomass pretreatment technology, microbial fermentation (mixed substrate and co-culture fermentation), the involvement of molecular biology techniques, and understanding of various factors (pH, T, addition of nanomaterials) effect on biohydrogen productivity and yield render this technology efficient and capable to meet future energy demands. Further integration of biohydrogen production technology with other products such as bio-alcohol, volatile fatty acids (VFAs), and methane have the potential to improve the efficiency and economics of the overall process. In this article, various methods used for lignocellulosic biomass pretreatment, technologies in trends to produce and improve biohydrogen production, a coproduction of other energy resources, and techno-economic analysis of biohydrogen production from lignocellulosic biomass are reviewed.

Engineering the surface of cuprous oxide via surface coordination for efficient catalysis on aerobic oxidation of benzylic alcohols under ambient conditions

The surface organometallic chemistry or surface coordination is considered as an important tool for modifying the surface properties and electronic structure of metal centres to achieve enhancement in catalysis. In this piece of work, we report how cuprous oxide (Cu2O) was turned into an efficient catalyst alongside with 2,2,6,6-tetra-methylpiperidine-1-oxyl (TEMPO) and N-methylimidazole (NMI) for catalytic aerobic oxidation of benzylic alcohols into aldehydes under ambient conditions through surface coordination. The coordination not only enhanced the capability of O-2-activation via the ligation of NMI to the metal sites, but also the surface structure was engineered in such a way that a vacancy was created for O-2-binding, one of the key steps as revealed by DFT calculations. Both experimental and theoretical results suggested that the coordination to the metal sites at the surface by NMI activated cuprous oxide via breaking up its oxo bridge at the surface to form hydroxyl group to allow O-2-binding, and increased also the electron density on the metal site to enhance its capability of O-2 activation. A plausible mechanism was proposed by using a variety of spectroscopic and electrochemical techniques as well as DFT calculations.

Chemoselective hydrogenation of alpha,beta-unsaturated carbonyl compounds using a recyclable Ru catalyst embedded on a bisphosphine based POP

Selective hydrogenation of the carbonyl functional group of alpha,beta-unsaturated carbonyl compounds affords industrially important allylic alcohols. However, achieving the selective reduction of the carbonyl group in the presence of the activated olefinic group is challenging. Therefore, the development of a highly chemoselective, efficient, and recyclable catalyst for this transformation is greatly desirable from the industrial and environmental viewpoints. In this study, a Ru-immobilized bisphosphine-based porous organic polymer (Ru@PP-POP) was used as an efficient heterogeneous catalyst for chemoselective hydrogenation of cinnamaldehyde (CAL) to cinnamyl alcohol with high chemoselectivity (98%) and excellent recyclability. To the best of our knowledge, the catalyst, Ru@PP-POP showed a high turnover number (970) and a high turnover frequency (240h(1)) which is the best activity obtained using a phosphine based heterogeneous Ru-catalyst in this transformation.

Enantiomer composition of chiral compounds present in traditional Slovak Tokaj wines

In the presented study volatile organic compounds (VOC) profiles of the most valuable products from Slovak Tokaj wine region were characterized using SPME-GC-MS. Identified volatile organic compounds in studied samples of Tokaj selection wines and Tokaj essences belonged to esters, terpenes, higher alcohols, volatile acids, lactones and aldehydes. From identified VOC, chiral compounds were selected, and their enantiomers were separated by heart-cut two-dimensional GC system. Enantiomer separation was optimized, and this advanced method was applied to determine enantiomeric ratios (ER) of studied compounds in 53 traditional botrytized Tokaj wines. Terpenic compounds linalool and limonene were present in ER resembling the racemic mixture, hotrienol expressed the slight dominancy of S-enantiomer (51-82 %) and S-alpha-terpineol varied from 47 to 70 %. Moreover, linalool and limonene were present only in wines of younger vintages. ER of 2,3-butanediol has shown the predominance of 2R,3R-enantiomer in all samples even though reached also values that were not usual for common white wines (55-100 %). Whiskey lactones were identified in all wines aged in oak barrels and exclusive presence of (4S,5S)-cisand (4S,5R)-transenantiomers was confirmed.

Technical application of a ternary alternative jet fuel blend – Chemical characterization and impact on jet engine particle emission

The use of alternative fuels is an essential element in future aviation. There are currently different approaches with regard to fuel production processes and feedstock materials. This requires flexible handling of available fuel quantities. The production of fuel mixtures (blends) is inevitable for an effective usage of commercially available fuel components. Within the framework of the project DEMO-SPK approx. 600 t of a ternary mixture (multiblend) of alternative jet fuels was produced and used in a real airport infrastructure at the airport Leipzig/Halle. Production and application were accompanied by extensive R&D activities to show that on-spec, semi-synthetic multiblends can be produced from several different synthetic fuels. One important aspect is the emission of soot particles from aircraft engines. The Multiblend Jet A-1 has been analyzed in a flow reactor setup regarding the formation of soot precursor compounds in comparison to a reference Jet A-1. The experiment revealed a lower formation of relevant soot precursors which also corresponds to the higher hydrogen content of the Multiblend Jet A-1 compared to the reference fuel. The lower soot formation in a real aircraft engine has been proven during ground runs of an A300-600 aircraft with PW4158 engines. The Multiblend Jet A-1 showed lower particle number and particle mass emission than the reference fuel. The difference to the reference fuel decreased with increasing power settings. In summary, the emission of particle mass is reduced by similar to 29 % and the number of emitted particles is reduced by similar to 37 % if the ICAO landing-and-take-off cycle is used for evaluation.

Alterations in Insulin Levels in Adults with Prenatal Alcohol Exposure

Objective Evidence suggests that prenatal alcohol exposure (PAE) may adversely impact insulin production and signaling but there is limited information on the range of these effects and their future health consequences. Method A prospective cohort of predominantly African-American individuals identified while in utero and followed into adulthood were used to evaluate differences in various indicators of diabetes, including fasting plasma glucose, hemoglobin A1c (HbA1c), and insulin levels. The homeostatic model assessment of insulin resistance (HOMA-IR) was also computed. Body mass index (BMI) was calculated and normal defined as < 25 kg/m(2). Participants were categorized as having PAE (n = 39) if their mothers drank at least 1 ounce of absolute alcohol per week or more during the 1(st) trimester of pregnancy and as Controls (n = 22) if their mothers reported abstaining from alcohol consumption during pregnancy. Results Mean age of the sample was 36.0 +/- 1.5 years. Indices of glucose metabolism, including fasting plasma glucose and hemoglobin A1c levels, did not vary by group status but insulin levels and HOMA-IR values varied by group status and BMI level. PAE individuals with a normal BMI had lower insulin levels than Controls. However, in PAE subjects, there was a steeper increase in insulin levels relative to their BMI than in Control subjects. A cluster of 5 PAE cases had low levels of insulin and 4 of the 5 had severe cognitive impairment. Conclusions The bidirectional effects on insulin level and insulin resistance associated with PAE may indicate differential rates of diabetes disease impact or differential PAE impact in the brain and peripheral areas involved in insulin production and signaling. These alterations may contribute to the metabolic disease risk associated with PAE. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 16545-68-9, in my other articles.

Blood-brain barrier integrity is the primary target of alcohol abuse

The effects of long-term alcohol consumptions on cognitive function remain elusive with contradictory results. Whilst it is widely accepted that long-term intoxication can cause cognitive impairment, moderate drinking can improve cognitive function. In reality, many older people and those with chronic medical conditions are long-term alcohol consumers in Asian countries. Our previous studies have suggested that long-term alcohol consumption can damage blood-brain barrier (BBB) integrity and aggravate cognitive deficit in APPswe/PS1De9 mice, but little is known about the underlying mechanisms, especially whether this consumption can cause cognitive decline via aggravating BBB damage in people who are exposed to the risk factors for cognitive disorders such as aging or inflammation. These questions were addressed in this study. The mouse models of cognitive deficit induced by D-galactose or lipopolysaccharide, the important risk conditions in human on cognitive function, were used to evaluate the effects of long-term alcohol consumption on the BBB integrity. After alcohol administration for 30 days in these models the BBB integrity was significantly destroyed with remarkably increased permeability and down-regulated protein expression of zonula occludens-1, VE-cadherin, occludin, low-density lipoprotein receptor-related protein-1, receptor for advanced glycation end products, major facilitator superfamily domain-containing protein-2a and aquaporin-4, which is the most closely related with the structure and function of BBB integrity. Meanwhile, the level of oxidative stress in D-galactose mice or inflammatory factors in cortex and serum in lipopolysaccharide mice, which might be involved in the cognitive dysfunctions, was significantly amplified. Furthermore, the impaired memory and hippocampal neuron damage induced by D-galactose and lipopolysaccharide were concurrently aggravated. Collectively, our study provided novel and compelling evidence that the structural and functional proteins for BBB integrity may be the primary targets for the detrimental effects of alcohol abuse that lead to cognitive dysfunction and neurological deficits in high risk populations.
