Training emotion regulation processes in alcohol-abstinent individuals: A pilot study

The study aimed to assess whether abstinent individuals with alcohol use disorders (AUD) would benefit from enhanced emotional regulation (ER) strategies using the affect regulation training (ART) program based on weekly sessions comprising psycho-education, muscle and respiratory relaxation, awareness, acceptance and tolerance, compassionate personal support, emotion analysis and modification. Seventy-two participants with AUD benefited from ART and were compared on their ER ability, mindfulness, and their experience of abstinence to 40 participants not receiving the program, before it, at the end, and 6 months after. Improvements in ER were observed, particularly in positive centration, action centration or self-blame and in mindfulness abilities after the program and six months later. In addition, by comparing participants who received the program with a short ( < 18 months) or long ( > 18 months) abstinence duration, the results showed a greater decrease in the use of non-adaptive strategies, a greater increase in adaptive strategies and mindfulness abilities in short-term abstinent individuals. These results demonstrate improvement in ER skills after training in people who were abstinent from alcohol. ART is effective for consolidating abstinence and should be used especially at the beginning of withdrawal to promote the rapid implementation of new ER strategies.

Family environment and depressive episode are associated with relapse after first-episode psychosis

Accessible summary What is known on the subject? Relapse rates are high among patients who have experienced first-episode psychosis (FEP). Psychotic relapses are associated with worse quality of life and poorer functionality of the FEP patient. The use of psychoactive substances, non-adherence to drug treatment, and high expressed emotion (EE) are notable predictors of relapse after the FEP. Although some studies have suggested that psychotic relapse may be associated with a family environment with high levels of emotional over-involvement (EOI), this finding is still inconsistent across different cultures. EE specific components must be evaluated and interpreted according to the context of cultural norms. There is a scarcity of studies on the role of depression in the occurrence of relapses after the FEP, and the results remain uncertain. What the paper adds to existing knowledge? This study explored the predictors of psychotic relapses in Brazilian patients who experienced FEP. Our results indicate that 29.2% of the patients relapsed after the FEP. Patients diagnosed with depression and high-EOI in the family environment were predictors of psychotic relapses in this population. This study expands knowledge about the cultural specificity of EOI and the role of depression in psychotic relapse. What are the implications for practice? Nursing professionals must consider the implications of the family environment and depression in the course of psychosis. Family interventions and the appropriate treatment of depression are important for improving the prognosis of FEP patients. Introduction Psychotic relapse may be associated with relatives’ high emotional over-involvement (EOI) and with a diagnosis of major depressive episode (MDE) among first-episode psychosis (FEP) patients, but the results are still inconsistent across different cultures. Aim Evaluate the predictors of relapse in FEP patients. Method Prospective cohort study with 6-month follow-up conducted with 65 dyads of patients and relatives from an early intervention unit in Brazil. At the baseline interview, relatives answered to a sociodemographic data form and to the Family Questionnaire. Patients provided sociodemographic and clinical data and answered the Measurement of Treatment Adherence; the Alcohol, Smoking and Substance Involvement Screening Test; the Severity of Dependence Scale to assess cannabis dependence, and the MDE module of the Mini-International Neuropsychiatric Interview. Psychotic relapses were evaluated using items from the Brief Psychiatric Rating Scale. The data were analysed using multiple logistic regression. Results 29.2% of the patients presented at least one psychotic relapse. High-EOI and MDE were predictors of psychotic relapses. Discussion Our findings expand the knowledge about the cultural specificity of EOI and the role of depression in psychotic relapse. Implications for practice Family nursing interventions and the appropriate treatment of MDE must be considered in the care of FEP patients.

Effects of vapourized THC and voluntary alcohol drinking during adolescence on cognition, reward, and anxiety-like behaviours in rats

Cannabis and alcohol co-use is prevalent in adolescence, but the long-term behavioural effects of this co-use remain largely unexplored. The aim of this study is to investigate the effects of adolescent alcohol and Delta(9)-tetrahydracannabinol (THC) vapour co-exposure on cognitive- and reward-related behaviours. Male Sprague-Dawley rats received vapourized THC (10 mg vapourized THC/four adolescent rats) or vehicle every other day (from post-natal day (PND) 28-42) and had continuous voluntary access to ethanol (10% volume/volume) in adolescence. Alcohol intake was measured during the exposure period to assess the acute effects of THC on alcohol consumption. In adulthood (PND 56+), rats underwent behavioural testing. Adolescent rats showed higher alcohol preference, assessed using the two-bottle choice test, on days on which they were not exposed to THC vapour. In adulthood, rats that drank alcohol as adolescents exhibited short-term memory deficits and showed decreased alcohol preference; on the other hand, rats exposed to THC vapour showed learning impairments in the delay-discounting task. Vapourized THC, alcohol or their combination had no effect on anxiety-like behaviours in adulthood. Our results show that although adolescent THC exposure acutely affects alcohol drinking, adolescent alcohol and cannabis co-use may not produce long-term additive effects.

Microalgal secondary metabolites: effect of climatic variables, seasons, and photocycles on the biogeneration of volatile organic compounds (VOCs)

Microalgae produce many metabolites with diversified structures that play important roles in their development. This work evaluated the effects of different climatic variables, seasons, and light/dark phases in the production of volatile organic compounds by Scenedesmus obliquus CPCC05, focusing on the simulation of climatic variables (average temperature, maximum light intensity, and light hours per day) of the extreme geographical positions of Brazil based on tropical Am, tropical Aw, and subtropical Cfa climates found in Joao Pessoa-PB, Rio Branco-AC, Boa Vista-RR, and Rio Grande-RS, in summer and winter seasons. For the best condition in this first step, the light/dark phases together with the residence time of the culture were evaluated. A total of 45 compounds were identified in all conditions studied. The main volatile groups found were hydrocarbons, aldehydes, ketones, alcohols, and terpenes identified in both geographic locations. Among these, hydrocarbons were the main biomarkers of the subtropical Cfa climate, while the ketone group was produced mainly in warmer climates, such as the Aw tropical climate. In the experiments of light/dark phases, a total of 34 compounds were identified. 2-Pentenol and decanal were only produced in the light phase, while 1-pentanol and 2-ethyl hexanol were only found in the dark phase. The main volatile compound found was 3-methylbutanol reaching a total area abundance of 14.10%. The major compounds detected during the cultures were originated and derived from the terpenoid pathways, fatty acids, and amino acid derivates.

Cotreatment of Small Gold Nanoparticles Protects Against the Increase in Cerebral Acetylcholinesterase Activity and Oxidative Stress Induced by Acute Ethanol Exposure in the Zebrafish

Gold nanoparticles (GNP) have emerged as an alternative to biomaterials in biomedical applications. Research has clearly demonstrated the relative safety and low toxicity of these molecules. However, the possible neuroprotective effect of GNP on the central nervous system (CNS) and its relationship with neurological and psychiatric disorders remain unclear. Zebrafish is a reliable model to investigate the impact of ethanol (EtOH) consumption on the CNS, including reward signaling such as the cholinergic neurotransmission system. Here, we investigated whether cotreatment or pretreatment with GNP prevented EtOH-induced changes in acetylcholinesterase activity and oxidative stress in the brain of zebrafish. We exposed adult zebrafish to 2.5 mg.L-1 GNP 1 h prior to EtOH (1% qv) treatment for 1 h, and cotreated adult zebrafish simultaneously with both substances for 1 h. Pretreatment with GNP did not prevent EtOH-induced increase in the acetylcholinesterase activity, whereas cotreatment with 2.5 mg.L-1 GNP and EtOH protected against this increase. The results also suggested similar protective effect on oxidative stress parameters in the zebrafish pretreated with GNP at 2.5 mg.L-1. GNP significantly decreased the levels of thiobarbituric acid reactive species and dihydrodichloroflu-orescein levels when cotreated with EtOH. GNP also prevented EtOH-induced increase in superoxide dismutase and catalase activities, suggesting a modulatory role of GNP in enzymatic antioxidant defenses. Our results showed that GNP was able to modulate the disruption of cholinergic and oxidative homeostasis in the brain of zebrafish. These findings indicate for the first time that zebrafish is an interesting perspective to investigate nanoparticles against disorders related to alcohol abuse. (C) 2021 IBRO.

Coupling heat curing and surface modification for the fabrication of high permselectivity polyamide nanofiltration membranes

Surface modification is an efficient post-treatment method to optimize the properties of nanofiltration (NF) membranes. Here, we report a facile surface modification strategy coupling with heat curing for grafting monoethanolamine (MEA), a monomer containing both a primary amine and a primary alcohol group, onto a nascent polyamide NF membrane. With grafting 0.5 wt% MEA at 50 degrees C, the pure water permeability of the polyamide NF membranes was improved from 7.9 to 19.5 L m(-2) h(-1) bar(-1) due to their enhanced physicochemical property, such as superior hydrophilicity, rough surface morphology, and enlarged membrane pores. Meanwhile, the rejection of Na2SO4 remained above 97.5%. More importantly, the optimal membrane modified with 0.5 wt% MEA exhibited a high Na2SO4 rejection of 99.1% and a negative NaCl rejection of -20.1% when treating a mixed salt solution containing 2 g/L Na2SO4 and 2 g/L NaCl. Our study provides a novel insight for the fabrication of high permselectivity NF membranes via surface modification.

Environmental-friendly electrospun phase change fiber with exceptional thermal energy storage performance

Electrospun phase change fiber (PCF) releases more than 85 wt% of organic solvents yet suffers from long-term thermal cycling-induced leakage. In this contribution, a novel PEG/PVA composite PCF was obtained by electrospinning their aqueous solution instead of using organic solvent in traditional method, which makes design of PCF towards green and cost-effective direction. Meanwhile, a simple surface crosslinking technology was applied to prevent leakage of PEG during the long-term service, and improve the thermal stability and tensile strength of the obtained crosslinked PCF (CPCF). The CPCF-50 shows the optimal morphological structure and exhibits the a relative high latent heat of 72.3 J/g. Owing to the confinement effect, CPCF exhibits robust thermal, chemical, and morphological stability with respect to 1000 thermal cycling. The CPCF also shows exceptional temperature regulation capability. The thermoregualting times of heating and freezing processes of CPCF-50 are 59.0% and 89.5% longer than those of the control and CPCF-0, respectively. Therefore, the eco-friendly and cost-effective prepared CPCF in this work, which exhibits relatively high latent heat and long-term reliability, paves a new way for the large-scale production of phase change fiber for thermal energy storage application.

Improving the gasoline properties by blending butanol-Al2O3 to optimize the engine performance and reduce air pollution

In this study, butanol, as an oxygenate additive and alumina as a nano metal particle, was mixed with pure gasoline. Different blends were tested, and operational tests were done on an engine with different engine speeds. Those additives were added to decrease air pollution due to the higher oxygen content of butanol, which can make combustion more complete, and nano metal additive, which has suitable potential to enhance engine performance, especially Brake Specific Fuel Consumption (BSFC). The results indicate that adding the additives mentioned above to the pure gasoline has led to an increase the engine performance. In this regard, the engine power has increased by 10% by adding alumina. Moreover, combining the base gasoline with additives enhances CO2 and reduces NOx and emissions of hydrocarbons. In this research, carbon monoxide was diminished by adding alcohol up to 50% in some conditions, and the emitted hydrocarbons through the atmosphere were declined by up to 20%. Moreover, optimization results showed that higher optimization is achieved when 5% of butanol and 1 g of alumina are used. Under these conditions, the results of CO, CO2, NOx and HC emissions were 1.099, 4.699, 113.9 and 77.5 ppm, respectively. (C) 2020 Elsevier Ltd. All rights reserved.

Differences in use of inhalants among sexual minorities in the USA in 2015-2018

Objectives: Inhalants are substances with underestimated abuse potential associated with cardiac problems, dizziness, seizures, and decreased level of consciousness. Inhalants are commonly used by the LGB population, who are vulnerable to their harms. US epidemiologic inhalants data are scarce. The aims of this study are to: i) investigate associations between inhalant use and sexual identity groups; ii) examine associations with use of other drugs among lesbian/gays who use inhalants. Methods: Data came from the 2015-2018 NSDUH (n = 168,560). Participants ages 18 or older were asked if they had used any inhalants in their lifetime and past-year. We investigated the associations between inhalant use with sexual identity categories heterosexual, lesbian/gay, and bisexual using logistic regression models with complex survey design. Results: Total prevalences of lifetime and past-year use of inhalants were 9.4% and 0.5%, respectively. Lesbian/ gay population (L/G) and bisexuals (B) reported higher odds of lifetime (L/G: aOR = 3.71, 95%CI = [3.19,4.30], B: aOR = 1.82, 95%CI = [1.64,2.03) and past-year (L/G: aOR = 11.57, 95%CI = [8.95,14.96], B: aOR = 2.81, 95%CI = [2.02,3.92]) inhalant use compared to heterosexuals. Among L/G, men had higher odds of lifetime (aOR = 4.11, 95%CI = [3.06,5.52]) and past-year (aOR = 15.67, 95%CI = [7.27,33.76]) inhalant use versus women. Use of marijuana (aOR = 2.76, 95%CI = [1.48,5.16]), other illegal drugs (aOR = 2.70, 95%CI = [1.60,4.56]), and non-medical use of psychotherapeutics (aOR = 2.67, 95%CI = 1.77,4.05) were associated with past-year use of inhalants among L/G. Conclusion: LGB population is at elevated risk of inhalant use and of concurrent use with other drugs. Gay men had significantly higher odds of inhalant use compared to lesbians and bisexuals. Informative and in-site harm reduction measures are warranted to prevent harms from inhalant use.

High genes: Genetic underpinnings of cannabis use phenotypes

Cannabis is one of the most widely used substances across the globe and its use has a substantial heritable component. However, the heritability of cannabis use varies according to substance use phenotype, suggesting that a unique profile of gene variants may contribute to the different stages of use, such as age of use onset, lifetime use, cannabis use disorder, and withdrawal and craving during abstinence. Herein, we review a subset of genes identified by candidate gene, family-based linkage, and genome-wide association studies related to these cannabis use phenotypes. We also describe their relationships with other substances, and their functions at the neurobiological, cognitive, and behavioral levels to hypothesize the role of these genes in cannabis use risk. Delineating genetic risk factors in the various stages of cannabis use will provide insight into the biological mechanisms related to cannabis use and highlight points of intervention prior to and following the development of dependence, as well as identify targets to aid drug development for treating problematic cannabis use.
