MACROSCOPIC AND MICROSCOPIC GASTROPROTECTIVE ACTIVITY OF MUCOADHESIVE GRANULE FORMULATIONS OF CLOVE LEAF ETHANOL EXTRACT

Gastric ulcers can be triggered by excessive HCl secretion, and the regenerative capacity of mucosal cells can be weakened by high alcohol levels and anti-inflammatory drugs, including NSAIDs. This study aims to evaluate the macroscopic and microscopic gastroprotective activity of clove leaf ethanol extract mucoadhesive granule formulations. The study used 25 rats divided into five groups: normal control, negative control, positive control, clove leaf ethanol extract group, and mucoadhesive granule formulation of clove leaf ethanol extract group. All groups except the normal control were administered acetylsalicylic acid. Treatments were conducted over 9 days, with surgical examination and observations performed macroscopically and microscopically on day 10. Macroscopic assessments revealed ulcer damage improvement in the positive control, extract, and mucoadhesive granule groups, all scored at 1. Microscopic assessments also indicated a significant difference between the negative control and the positive control, extract, and mucoadhesive granule groups, showing better gastric repair, scored at 0.5. Therefore, it can be concluded that the administration of the mucoadhesive granule formulation of clove leaf ethanol extract exhibits gastroprotective activity comparable to that of the clove leaf ethanol extract

Concurrent substance use among cancer patients with and without a history of cannabis use since cancer diagnosis at an NCI-Designated Cancer Center in Florida.

Although substance use may have adverse impacts on cancer outcomes, little is known regarding patterns of concurrent substance use with cannabis among cancer patients. Our objective was to examine predictors of concurrent substance use with cannabis among cancer patients since their cancer diagnosis and explore perceptions of cannabis among these patients. Patients treated at a National Cancer Institute-designated comprehensive cancer center were invited to participate in an electronic survey regarding medical cannabis from August to November 2021. Survey data were linked to internal data resources including electronic health records and patient intake forms to obtain history of substance use (defined as within at least 3 months of cancer diagnosis) of cigarettes, injection drugs, high levels of alcohol, or clinically unsupervised prescription drugs (total n = 1094). Concurrent substance users were defined as those with any reported substance use and cannabis use at the time of cancer diagnosis. We used descriptive statistics (χ2 or exact tests) to compare groups and estimated adjusted odds ratios (AORs) with 95% confidence intervals (CIs) to identify predictors of substance use among users and nonusers of cannabis. Approximately 45% (n = 489) of the sample reported cannabis use since their cancer diagnosis. Of patients who reported using cannabis, 20% self-reported concurrent polysubstance use, while 8% of cannabis nonusers reported substance use (P < .001). Among patients who use cannabis, those who reported 2 or more self-reported treatment-related symptoms (eg, pain, fatigue) were more likely to have self-reported concurrent substance use (AOR = 3.15, 95% CI = 1.07 to 9.27) compared with those without any symptoms. Among nonusers, those with lower educational background were more likely to have a history of concurrent substance use (AOR = 3.74, 95% CI = 1.57 to 8.92). Patients who use cannabis with concurrent substance use were more likely to report improved sleep (P = .04), increased appetite (P = .03), and treatment of additional medical conditions (P = .04) as perceived benefits of cannabis use. High symptom burden may be associated with concurrent substance use with cannabis among cancer patients.

Marital Quality-A Neglected Player in the Prevention of Cardiovascular Diseases: A Systematic Review of Longitudinal Studies.

Marital quality (MQ) is a psychosocial factor that has been neglected in cardiovascular prevention guidelines, although its association with cardiovascular diseases has been identified in several studies. Therefore, we aim to investigate how MQ either in positive or negative dimensions affect different cardiovascular risk factors and diseases. We systematically searched different databases in September 2023 for longitudinal studies conducted to assess the contribution of MQ to well-established cardiovascular risk factors and diseases. Two independent researchers screened studies and carried out data extraction and quality assessment of included ones. From 12,175 potential studies screened, 40 were included. The presence of significant heterogeneity in methodology, follow-up, and subsequent effect estimates made it unfeasible to do a meta-analysis. Despite the variation, most studies found a significant association of negative MQ measures with physical inactivity (2/2), high levels of smoking (4/5) and alcohol (3/3) use, increased metabolic syndrome risk (3/3), elevated type 2 diabetes mellitus (T2DM) risk and poor T2DM management (3/6), elevated cardiovascular disease risk and progression (9/11), increased body weight and obesity risk (2/3), elevated blood pressure and hypertension risk (7/8). Positive MQ measures were mainly associated with improvement in blood pressure control (2/2), reduced T2DM risk and its good management (1/1), reduced body weight and obesity risk (2/2), and increased survival in cardiovascular diseases (4/4). Based on current evidence, MQ seems to play a crucial role in developing established cardiovascular risk factors and diseases and is worth considering in preventive strategies.

Associations Between Alcohol Use, Antiretroviral Therapy Use, and Viral Load Suppression Among People Living with HIV in Rural Central Uganda

Alcohol use among people living with HIV (PWH) is common and may negatively affect engagement in HIV care. We evaluated the relationships between alcohol use, ART use, and viral suppression among PWH in Uganda. PATH/Ekkubo was a trial evaluating a linkage to HIV care intervention in four Ugandan districts, Nov 2015-Sept 2021. Our analytical sample included: (1) baseline data from individuals not enrolled in the intervention trial (previously diagnosed HIV+); and 12-month follow-up data from the control group (newly diagnosed or previously diagnosed, but not in care). Level of alcohol use was categorized using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C): none (AUDIT-C = 0), low (women = 1–2, men = 1–3), medium (women = 3–5, men = 4–5), high/very high (6–12). Multivariable logistic regression models evaluated associations between alcohol use, ART use and viral suppression (a viral load of < 20); we also stratified by gender. Among 931 PWH, medium (OR: 0.43 [95% CI 0.25–0.72]) and high/very high (OR: 0.22 [95% CI 0.11–0.42]) levels of alcohol use were associated with lower odds of being on ART. In a sub-sample of 664, medium use (OR: 0.63 [95% CI 0.41–0.97]) was associated with lower odds of viral suppression. However, this association was not statistically significant when restricting to those on ART, suggesting the relationship between alcohol use and viral suppression is explained by ART use. Among men, high/very high, and among women, medium alcohol use levels were associated with lower odds of being on ART and being virally suppressed. Interventions for PWH who use higher levels of alcohol may be needed to optimize the benefits of Uganda’s Universal Test and Treat strategy.

Key role of K+ and Ca2+ in high-yield ethanol production by S. Cerevisiae from concentrated sugarcane molasses

BackgroundSaccharomyces cerevisiae is an important microorganism in ethanol synthesis, and with sugarcane molasses as the feedstock, ethanol is being synthesized sustainably to meet growing demands. However, high-concentration ethanol fermentation based on high-concentration sugarcane molasses—which is needed for reduced energy consumption of ethanol distillation at industrial scale—is yet to be achieved.ResultsIn the present study, to identify the main limiting factors of this process, adaptive laboratory evolution and high-throughput screening (Py-Fe3+) based on ARTP (atmospheric and room-temperature plasma) mutagenesis were applied. We identified high osmotic pressure, high temperature, high alcohol levels, and high concentrations of K+, Ca2+, K+ and Ca2+ (K+&Ca2+), and sugarcane molasses as the main limiting factors. The robust S. cerevisiae strains of NGT-F1, NGW-F1, NGC-F1, NGK+, NGCa2+ NGK+&Ca2+-F1, and NGTM-F1 exhibited high tolerance to the respective limiting factor and exhibited increased yield. Subsequently, ethanol synthesis, cell morphology, comparative genomics, and gene ontology (GO) enrichment analysis were performed in a molasses broth containing 250 g/L total fermentable sugars (TFS). Additionally, S. cerevisiae NGTM-F1 was used with 250 g/L (TFS) sugarcane molasses to synthesize ethanol in a 5-L fermenter, giving a yield of 111.65 g/L, the conversion of sugar to alcohol reached 95.53%. It is the highest level of physical mutagenesis yield at present.ConclusionOur results showed that K+ and Ca2+ ions primarily limited the efficient production of ethanol. Then, subsequent comparative transcriptomic GO and pathway analyses showed that the co-presence of K+ and Ca2+ exerted the most prominent limitation on efficient ethanol production. The results of this study might prove useful by promoting the development and utilization of green fuel bio-manufactured from molasses.

Adolescent alcohol binge drinking and withdrawal: behavioural, brain GFAP-positive astrocytes and acute methamphetamine effects in adult female rats

RationaleAlcopop beverages are generally the first alcoholic beverage that young females drink which contain high levels of sugar and alcohol. The over-consumption of these drinks may encourage alcohol co-administration with methamphetamine (METH) impacting on drinking behaviour and glial function.AimsThe aims of this study were to evaluate the effect of adolescent binge alcohol exposure on consumption level, anxiety-like behaviour, cross-sensitization with METH and on astrocyte expression in reward related brain regions.MethodsAdolescent female Sprague-Dawley rats had daily 1-hour oral alcohol consumption of alcopop (ALCP; with sucrose) or ethanol-only (ETOH; without sucrose), transitioned from 5 to 15% (v/v) ethanol content for 34 days. Water and sucrose groups act as controls. During alcohol withdrawal, rats were tested for anxiety on the elevated plus maze (EPM) and locomotor activity following saline or METH (1 mg/kg i.p) treatment. Brains were then collected to assess astrocyte immunofluorescence for glial fibrillary acidic protein (GFAP) in reward-related brain regions.ResultsRats pretreated with 5% ALCP consumed significantly more volume and ethanol intake when compared to 5% EtOH rats. Both ALCP and EtOH groups had a higher preference ratio for 5% than 15% alcohol solutions and ALCP rats had greater ethanol intake at 15% than EtOH rats. Alcohol withdrawal showed no significant differences between groups on anxiety, METH cross-sensitization effects or GFAP intensity in the regions studied.ConclusionsOverall, the addition of sucrose to alcoholic solutions encouraged female rats to consume larger volumes and greater ethanol intake compared to ethanol-only solutions, yet did not have long lasting effects on behaviour and astrocytes.

Gender differences in substance use and associated factors among urban refugees in Uganda

ABSTRACT Background: Alcohol and other substances use related problems among refugees is a global public health concern. Although there is substantial research on the use of alcohol and other substances among the refugees, little is known about gender and other factors that might be associated with the use of alcohol and other substances. Our study aimed to assess the prevalence of alcohol and substance use across gender and other specific associated factors among urban refugees living in Mbarara city, Southwestern Uganda. Methods: In a cross-sectional study, 343 refugees were interviewed on the use of alcohol and other substances using the Alcohol Use Disorder Identification Test and the Drug Abuse Screening Test. The associated factors included, age, marital status, occupation, duration (length of stay) in Uganda, educational levels, stigma and depression. Linear regression analysis was used to examine the associations between the predictor and outcome variables. Results: No significant gender difference in alcohol use was found, and the overall prevalence of hazardous, harmful or dependent alcohol use among our sample of refugees living in Mbarara city was 43%. There were however, statistically significant gender differences in the use of other substances, with a significantly higher percentage of men than women reporting intermediate, substantial, or severe substance use (45% among men, 37% among women). Higher levels of depression and being separated from one’s spouse were associated with higher levels of alcohol and substance use. In addition, higher age and being male were associated with the use of substances other than alcohol. Conclusions: Our findings indicate a high prevalence of problematic alcohol and substance use among both male and female refugees. Clinical interventions focused on the treatment and prevention of alcohol and substance use among the refugee communities may benefit from focusing on depressive symptoms as well.

Investigation of microbial succession and volatile compounds dynamics during the fermentation of traditional cereal vinegar in Xinjiang

Cereal vinegar, a traditional acidic condiment in China. The quality of cereal vinegars varies depending on the raw materials used to produce them, fermentation methods and brewing environments. To investigate the microbial community succession and metabolite changes on the whole fermentation process of traditional cereal vinegar in Xinjiang, we analyzed it by high-throughput sequencing, high-performance liquid chromatography and head space solid phase micro-extraction-gas chromatography-mass spectrometry technology. The acetic acid (5733.33 mg/100 g), lactic acid (1265.33 mg/100 g) and succinic acid (520.00 mg/100 g), gallic acid (63.09 μg/g) and vanillic acid (29.05 μg/g) were the dominant organic acids and phenolic compounds in traditional cereal vinegar of Xinjiang, respectively. In later stage of aging, high levels of acetoin, ethyl phenylacetate, phenylethyl alcohol and ethyl lactate endowed the cereal vinegar with rosy, fruity and creamy aroma. The functional fungal genera were Saccharomyces, Fusarium and Kazachstania, and the functional bacterial were Pseudomonas, Lactobacillus, Acetobacter, Rhodococcus and Methylobacterium. Spearman's correlation coefficient showed that bacterial community had a strong correlation with various flavor compounds. The results could provide a theoretical reference for flavor enhancement and process improvement of traditional cereal vinegar in Xinjiang.

“It’s called homophobia baby” exploring LGBTQ + substance use and treatment experiences in the UK

Introduction Gender and sexual minority/minoritized groups are at a higher risk of substance misuse and related harm compared to the rest of the population. However, limited research has focused on understanding the extent of these issues and the support needs of all minoritized groups within the LGBTQ + population. Methods This qualitative cross-sectional survey sought to explore LGBTQ + individuals’ perspectives on substance use and treatment experiences. Researchers used a manual thematic analysis approach to thoroughly study the data, examining each part closely to uncover themes and patterns. Co-produced with stakeholders and developed with input from LGBTQ + individuals with lived experience, the survey included 38 participants across the UK. Results Cannabis (83% n = 20), ecstasy (68% n = 15), and cocaine (67% n = 16) were commonly used substances, while some participants (19% n = 6) reported consuming high levels of alcohol. Many respondents highlighted the role of “stigma” and peer pressure within the LGBTQ + communities as a motivator for substance use. Participants expressed a preference for informal support due to fears of “discrimination” from formal treatment services. Conclusions The study underscores the need for research inclusive of all LGBTQ + groups and highlights the importance of tailored interventions that address the diverse needs of LGBTQ + individuals. Further exploration of peer-led interventions is necessary to assess their effectiveness. The findings emphasize the necessity of person-centered treatment approaches that recognize the heterogeneity of service users.

Effect of Different Levels of Cider, Baker Yeast and Hamei on Pineapple Cider

Cider is an alcoholic beverage that is produced when fruit juices are fermented; it is made using the same techniques as wine. Cider occupies a special place among its more well-known alcoholic siblings since it is brewed like wine but mostly served as beer. Eight treatments were reproduced three times in the CRD (Complete Randomized Design) format of the experiment. The pineapples were fermented by using two different kinds of yeast, baker yeast (Saccharomyces cerevisiae) and Hamei (Bacteria (Bacillus sp.), fungi (Aspergillus niger van Tiegh.) and the yeast (Saccharomyces cerevisiae) for 30 days. Longer fermentation times resulted in higher levels of alcohol, acidity, and sensory characteristics, but lower levels of total soluble solids, pH, and specific gravity were observed. Cider is a fermented product, produced from fruit juices, which increases juice’s shelf life. In this experiment, Hamei and baker yeast were used to make pineapple cider. Treatment T5 (Pineapple pieces (700 g) + Sugar (300g) + Hamei (0.5g) + Water (1L) produced the best cider among all the treatments in terms of alcohol content (7.00), pH (3.90) and total soluble solids (4.90 Brix).

Intermittent-access operant alcohol self-administration promotes binge-like drinking and drinking despite negative consequences in male and female heterogeneous stock rats

The study of Alcohol Use Disorders (AUD) in preclinical models is hampered by difficulty in training rodents to voluntarily consume high levels of alcohol. The intermittency of alcohol access/exposure is well known to modulate alcohol consumption (e.g., alcohol deprivation effect, intermittent-access two-bottle-choice) and recently, intermittent access operant self-administration procedures have been used to produce more intense and binge-like self-administration of intravenous psychostimulant and opioid drugs. In the present study, we sought to systematically manipulate the intermittency of operant self-administered alcohol access to determine the feasibility of promoting more intensified, binge-like alcohol consumption. To this end, 24 male and 23 female NIH Heterogeneous Stock rats were trained to self-administer 10% w/v ethanol, before being split into three different-access groups. Short Access (ShA) rats continued receiving 30-min training sessions, Long Access (LgA) rats received 16-h sessions, and Intermittent Access (IntA) rats received 16-h sessions, wherein the hourly alcohol-access periods were shortened over sessions, down to 2 min. IntA rats demonstrated an increasingly binge-like pattern of alcohol drinking in response to restriction of alcohol access, while ShA and LgA rats maintained stable intake. All groups were tested on orthogonal measures of alcohol-seeking and quinine-punished alcohol drinking. The IntA rats displayed the most punishment-resistant drinking. In a separate experiment, we replicated our main finding, that intermittent access promotes a more binge-like pattern of alcohol self-administration using 8 male and 8 female Wistar rats. In conclusion, intermittent access to self-administered alcohol promotes more intensified self-administration. This approach may be useful in developing preclinical models of binge-like alcohol consumption in AUD.

Alcoholic and non-alcoholic rosé wines made with Saccharomyces cerevisiae var. boulardii probiotic yeast

The production of alcoholic and non-alcoholic rosé winesusing Saccharomyces cerevisiae var. boulardii probiotic yeast is described in this study for the first time. Before and after fermentation and distillation, the volatile acidity, lactic, and malic acid levels were evaluated for S. cerevisiae var. boulardii. These contents were compared to those obtained with a standard S. cerevisiae EC-1118 yeast. We measured the levels of gluconic acid and free amino nitrogen in the musts. After fermentation and distillation, yeast viability was assessed as a function of time (0, 15days, 3months, and 6months), both at ambient temperature (25 ± 0.5 °C) and refrigerator temperature (4 ± 0.5 °C). The outcomes revealed that the rosé wine made with S. cerevisiae var. boulardii had the same values and preliminary sensory characteristics as other commercial wines made with S. cerevisiae EC-1118. The S. cerevisiae var. boulardii yeast successfully survived the high alcohol level produced during fermentation and vacuum distillation. The study also revealed that this unique rosé wine retains its probiotic viability for at least 6 months when stored at room temperature or in the refrigerator, making it a suitable candidate for large-scale production where long storage intervals are required by both producers and consumers.

Traumatic brain injury in college students and the influence of alcohol consumption: A retrospective review from a rural state.

There is a strong association between alcohol consumption and traumatic brain injury (TBI). Students are known to consume alcohol at a high rate. Despite the connection between alcohol and TBI, this is one of few studies to examine the connection between students, alcohol, and TBI. The objective of this study was to explore the relationship between students, alcohol, and TBI. A retrospective chart review utilizing the institutional trauma data back was performed for patients 18-26 years of age, admitted to the emergency department with a diagnosis of a TBI and positive blood alcohol. Patient diagnosis, injury mechanism, alcohol level on admission, urine drug screen, mortality, injury severity score, and discharge disposition were recorded. The data were analyzed using Wilcoxon rank-sum tests and Chi-square tests to identify differences between students and non-student groups. Six hundred and thirty-six charts were reviewed for patients aged 18-26 with a positive blood alcohol level and TBI. The sample included 186 students, 209 non-students, and 241 uncertain of status. The student group had significantly higher levels of alcohol than the non-student group (P < 0.0001). P < 0.0001 showed that overall alcohol levels for males are significantly higher than levels of alcohol for females in the student group. Alcohol consumption contributes to significant injuries such as TBI in college students. Male students had a higher prevalence of TBI, and higher alcohol levels than female students. These results can be used to inform and better target harm reduction and alcohol awareness programs.

ANALYSIS OF THE CAUSES OF SUDDEN DEATH AMONG EMPLOYEES OF JSC «RUSSIAN RAILWAYS»

A retrospective analysis was carried out of all cases of sudden death of employees of Russian Railways in the period from 2009 to 2021. All deceased workers were conditionally divided into 6 groups depending on the professions and positions of workers. All 411 deceased patients worked on 16 railways, subordinate to 15 medical directorates of Russian Railways. 84.7% of patients felt the first symptoms during working hours and only 15.3% during non-working hours. The prevalence of cases of sudden death during working hours was noted - 81%. Among the occupational groups under consideration, death at home or outside the home was more often observed in groups I and VI, and at the workplace, from groups II to V (p < 0.001). 6.8% of those who died had high levels of ethyl alcohol in their blood, and 3 out of 4 of them died at the workplace. Among the deceased, 70.3% of the patients were smokers. 68.1% were overweight or obese. The level of total cholesterol exceeded 5 mmol/l in 20.7% of cases, and the largest number of patients (65%) had a moderate risk according to the SCORE scale. The study sample showed that cardiovascular diseases are the main cause of sudden death. Among the risk factors in the study group, smoking and obesity prevailed.

Fatalities in Swedish fire-related car crashes from a toxicologic perspective

Objective: Vehicle materials developments raise concerns about new patterns of vehicle fire toxic gas emissions. This study aimed to describe toxicologic components in a recent material of fatal car crashes on Swedish roads in which the vehicle caught fire and compare the results to a previous material. Methods: Retrospective registry study. All fatal car crashes with fire in Sweden 2009–2018 were extracted from the Swedish Transport Administration’s In-Depth Studies Database and compared with an earlier study of the time period 1998–2008. Results: A total of 79 crashes and 94 fatalities were included. Carbon monoxide (COHb) blood levels >10% were found in 13 cases. Hydrogen cyanide (HCN) blood levels 0.1–1.7 µg/g were found in 10 cases. In 29 of the cases the person had a blood alcohol level (BAC) >0.2‰, which is the legal driving limit in Sweden. A total of 15 people died due to burn injuries and 2 individuals died due to toxic gas emissions without any other fatal traumatic injury. Total number of deaths in fire-related crashes halved from 181 (1998–2008) to 94 (2009–2018) but the percentage of fatalities in burning vehicles was unaltered (5% vs. 6%). The proportion of fatalities with HCN in the blood increased from 2% between 1998–2008 to 10% during 2009–2018 (p = 0.006). The age of the car involved in a crash increased by 0.26 years per calendar year (p = 0.001). Conclusions: The proportion of fatalities with measured levels of HCN in the blood has increased. Eleven of the 15 burn injury fatalities had high levels of alcohol, HCN, or COHb, possibly contributing to an inability to leave a burning vehicle. Faster rescue brought by improved specific education and training of ambulance and rescue services personnel may be of future importance, as may on-scene antidote administration and revised regulations of vehicle flammability.

Characterization of a new Saccharomyces cerevisiae isolated from banana stems and its mutant with l-leucine accumulation for awamori brewing.

We isolated a new strain of the yeast Saccharomyces cerevisiae, 35a14, from banana stems in Okinawa. This strain did not belong to any industrial yeast groups in a phylogenetic tree and produced high levels of alcohol. Furthermore, awamori, an Okinawa's traditional distilled alcoholic beverage, brewed with an l-leucine overproducing mutant derived from 35a14 showed a high concentration of isoamyl acetate.

Number of participants in multiple perpetrator sexual aggressions

AbstractThe present study aims to explore differences between lone, duo and 3+ group sexual aggressions by adult strangers from a Spanish sample based on victims' and offenders' socio‐demographic characteristics and sexual offences. Additionally, the study aims to provide evidence of whether duo offences should be considered a different category that MPR and whether we can differentiate them from lone and 3+ group offenders. A sample of 400 sexual stranger offenders whose victims were women over 13 years of age has been analysed to find differences and predictive variables for lone (N = 298), duo (N = 43) and 3+ group (N = 59) sexual aggressions. Kruskal–Wallis tests and chi‐squared analysis were used to compare the three groups and then multinomial logistic regression analysis were conducted to identify the predictive variables of group size. Results support previous studies comparing group sexual offences by its size; and that duos could be a singular category with more similarities with multiple perpetrator rape offences (age and ethnicity of offenders, similar violent control and sexual behaviour during the aggression). Some singularities have also been encountered, such as higher levels of alcohol and drug use of the perpetrators; severe consequences of their actions with more injuries to their victims; use of weapons; and less use of vehicles, which can be related to crime locations that are rarely outdoors.

A latent class approach to understanding longitudinal sleep health and the association with alcohol and cannabis use during late adolescence and emerging adulthood

ObjectiveSleep is a multi-dimensional health behavior associated with elevated risk of substance use. This is the first study to utilize a latent class approach to characterize sleep health across multiple dimensions and across time from late adolescence to emerging adulthood, and to examine associations with alcohol and cannabis use trajectories. MethodsThe sample included 2995 emerging adults (mean ages = 18 to 24 years across six waves of data collection; 54% female) who provided data on sleep dimensions (quality, duration, and social jetlag) and frequency and consequences of alcohol and cannabis use. Longitudinal latent class analysis (LLCA) models characterized participants according to the three sleep dimensions. Latent growth models examined trajectories of frequency and consequences of alcohol or cannabis use over time among emergent sleep classes, with and without controlling for covariates. ResultsLLCA models identified four sleep classes: good sleepers (n = 451; 15.2%); untroubled poor sleepers (n = 1024; 34.2%); troubled, moderately good sleepers (n = 1056; 35.3%); and suboptimal sleepers (n = 460; 15.4%). Good sleepers reported significantly lower levels of alcohol or cannabis use and consequences, and less of an increase in alcohol consequences as compared to suboptimal sleepers. ConclusionsPersistent poor sleep health was associated with higher levels of alcohol and cannabis use and consequences, and greater increases in alcohol-related consequences during the transition from late adolescence to emerging adulthood. Findings have important clinical implications, highlighting that addressing multi-dimensional sleep health may be an important, novel target of intervention to reduce substance use frequency and consequences.

Microbial succession and exploration of higher alcohols-producing core bacteria in northern Huangjiu fermentation

Higher alcohols (HAs) are abundant compounds that provide important flavors in Huangjiu, but they also cause hangover. Previous studies have shown the production of HAs to be related to yeast, but the correlations between HAs and other microorganisms are rarely reported. In this study, we detected changes in levels of HAs and microbial dynamics during the Huangjiu fermentation process. Relationships were characterized using Pearson’s correlation coefficient. The functional core HA-producing bacteria were selected by bidirectional orthogonal partial least squares (O2PLS). The result showed that 2-methyl-1-propanol, phenethyl alcohol and 3-methyl-1-butanol were the principle HAs present at high levels. Lactococcus and Saccharomyces were predominant at the genus level of bacteria and fungi, respectively. A total of 684 correlations between HAs and microorganisms were established. Five genera were screened as functional core HA-producing bacteria. Our findings might provide some new inspiration for controlling the content of HAs, enhancing international prestige and market expansion of Huangjiu.

Patterns of Prescription Medicine, Illicit Drugs, and Alcohol Misuse among High-Risk Population: A Factor Analysis to Delineate Profiles of Polydrug Users.

Polydrug use is a serious health and social problem worldwide. Treatment remains a challenge because it requires planning based on estimates of the nature and extent of drug consumption and the characteristics of the population in need. To this end, 103 subjects, who voluntarily asked to begin rehabilitation treatment, were monitored through hair analysis to investigate the nature and extent of their polydrug use. A factor analysis was carried out to delineate polydrug user profiles based on the following variables: age, sex, type of illicit drug use, type of prescription drug misuse, and amount of alcohol consumption. Twenty-three percent of subjects tested positive to more than one illicit drug (mainly cocaine), 44% to unprescribed drugs (mainly benzodiazepines), and 66% were hard drinkers. The profiles of drug users outlined included “single drug cocaine user”, and “single drug opiate user”. Moreover, a particularly problematic profile of cocaine users, common between genders and age groups, who combine high levels of alcohol and unprescribed benzodiazepines and opiates, emerged (“hard polydrug abusers”). From a treatment policy perspective, these findings support the importance of preventive analysis before rehabilitation treatment begins in order to identify different patterns of drug abusers to implement personalized multidisciplinary measures.
