RESUMEN

The world has a higher count of death rates as a result of Alcohol consumption. Identification is possible because Alcoholic EEG waves have a certain behavior that is totally different compared to the non-alcoholic individual. The available approaches take longer to provide the feedback because they analyze the data manually. For this reason, in the present paper we propose a novel approach applied to detect alcoholic EEG signals automatically by using deep learning methods. Our strategy has advantages as far as fast detection is concerned; hence people can help immediately when there is a need. The potential for a significant decrease in deaths from alcohol poisoning and improvement to public health is presented by this advancement. In order to create clusters and classify the alcoholic EEG signals, this research uses a cascaded process. To begin with, an initial clustering and feature extraction is done by LASSO regression. After that, a variety of meta-heuristics algorithms like Particle Swarm Optimization (PSO), Binary Coding Harmony Search (BCHS) as well as Binary Dragonfly Algorithm (BDA) are employed for feature minimization. When this method is used, normal and alcoholic EEG signals may be differentiated using non-linear features. PSO, BCHS, and BDA features allow for estimation of statistical parameters through t-test, Friedman statistic test, Mann-Whitney U test, and Z-Score with corresponding p-values for alcoholic EEG signals. Lastly, classification is done by the use of support vector machines (SVM) (including linear, polynomial, and Gaussian kernels), random forests, artificial neural networks (ANN), enhanced artificial neural networks (EANN), and LSTM models. Results showed that LASSO regression with BDA-based EANN proposed classifier have a classification accuracy of 99.59%, indicating that our method is highly accurate at classifying alcoholic EEG signals.

RESUMEN

The National Institute on Alcohol Abuse and Alcoholism's (NIAAA) definition of alcohol use disorder (AUD) recovery stipulates two criteria: remission from DSM-5 AUD and cessation of heavy drinking. Importantly, these criteria allow for consideration of nonabstinent alcohol treatment outcomes. However, researchers have yet to assess potential predictors of the NIAAA recovery outcome. The current study examined associations between mental health and coping predictors of NIAAA recovery status in an AUD treatment sample. At baseline (BL) and end-of-treatment (EOT) research interviews in a clinical trial, participants (N = 118) completed questionnaires assessing alcohol dependence, mental health, and confidence levels in reducing heavy drinking, as well as alcohol use and DSM-5 AUD symptom endorsement. Logistic regression models tested the associations between chosen predictors and the odds of achieving NIAAA recovery. Twenty-four percent of individuals (n = 28) met both criteria for NIAAA recovery at EOT. Higher levels of BL state anxiety and anxiety sensitivity predicted lower odds of achieving NIAAA recovery, while greater confidence to reduce heavy drinking predicted increased odds of NIAAA recovery. Social workers are encouraged to continue assessing and addressing mental health in AUD treatment to help individuals with alcohol problems achieve their AUD recovery goals.

RESUMEN

Fetal alcohol spectrum disorder (FASD) and its associated physical and mental conditions is the most prevalent congenital impairment causing developmental and intellectual disability worldwide. Like alcohol abuse, FASD is typically undiagnosed by primary care providers. And like alcohol abuse, life underwriters and medical directors need to be aware of the signs, symptoms, and behaviors associated with FASD to accurately detect, identify, evaluate and assess the mortality risk. Three cases of suspected undiagnosed FASD that were underwritten for life expectancies in legal matters are discussed in this report. Not only were these patients' risks for excess mortality elevated due to their initial neurologic injury due to prenatal exposure to alcohol, but these cases demonstrate the importance of the stability and care needed to make them insurable. The following paper discusses the clinical and social settings at birth that may give underwriters and medical directors some clue to a potential case of the child having FASD and then to assess their statistical and lifestyle mortality risks.

RESUMEN

BACKGROUND: Telemedicine-based interventions show promise in addressing mental health issues among rural populations, yet evidence regarding their impact among the health care workforce in these contexts remains limited. OBJECTIVE: This study aimed to evaluate the characteristics and the responses and perceptions of recently graduated physicians who work in rural areas of Peru as part of the Servicio Rural Urbano Marginal en Salud (Rural-Urban Marginal Health Service [SERUMS], in Spanish) toward a telehealth intervention to provide remote orientation and accompaniment in mental health. METHODS: A mixed methods study was carried out involving physicians who graduated from the Universidad Nacional Mayor de San Marcos and participated in the Mental Health Accompaniment Program (MHAP) from August 2022 to February 2023. This program included the assessment of mental health conditions via online forms, the dissemination of informational materials through a website, and, for those with moderate or high levels of mental health issues, the provision of personalized follow-up by trained personnel. Quantitative analysis explored the mental health issues identified among physicians, while qualitative analysis, using semistructured interviews, examined their perceptions of the services provided. RESULTS: Of 75 physicians initially enrolled to the MHAP, 30 (41.6%) opted to undergo assessment and use the services. The average age of the participants was 26.8 (SD 1.9) years, with 17 (56.7%) being female. About 11 (36.7%) reported have current or previous mental health issues, 17 (56.7%) indicating some level of depression, 14 (46.7%) indicated some level of anxiety, 5 (16.6%) presenting a suicidal risk, and 2 (6.7%) attempted suicide during the program. Physicians who did not use the program services reported a lack of advertising and related information, reliance on personal mental health resources, or neglect of symptoms. Those who used the program expressed a positive perception regarding the services, including evaluation and follow-up, although some faced challenges accessing the website. CONCLUSIONS: The MHAP has been effective in identifying and managing mental health problems among SERUMS physicians in rural Peru, although it faced challenges related to access and participation. The importance of mental health interventions in this context is highlighted, with recommendations to improve accessibility and promote self-care among participants.

RESUMEN

Abdominal pain in patients with significant alcohol use and smoking history presents diagnostic challenges due to overlapping clinical features of complications like acute cholecystitis and peptic ulcers. The unreliable physical examinations of intoxicated patients often complicate accurate diagnosis. We present a case of a 56-year-old male with a history of alcoholism and smoking, who presented to the emergency department with nonspecific abdominal pain. Initial imaging suggested cholecystitis, but due to the patient's intoxication, his physical examination was unreliable. During a laparoscopic cholecystectomy, a perforated prepyloric ulcer was unexpectedly discovered, sealed by the gallbladder. This case highlights the limitations of relying solely on imaging for diagnosing abdominal conditions in intoxicated patients. The intraoperative discovery of the perforated ulcer necessitated a shift in the surgical approach, emphasizing the need for flexibility in surgical planning and a high index of suspicion for other abdominal pathologies in patients with significant lifestyle risks. The successful management of this patient through adaptive surgical techniques and comprehensive postoperative care, including Helicobacter pylori eradication therapy, underscores the importance of maintaining a broad differential diagnosis and readiness to adapt surgical plans. This approach is essential for managing complex cases effectively, ensuring that both the immediate surgical issues and underlying causes are addressed to optimize recovery and prevent recurrence.

RESUMEN

Daniel Webster (1782-1852) was one of the most impactful United States political figures of the early and mid-nineteenth century. He served in Congress and as the Secretary of State for three Presidents. He died in October of 1852 and his autopsy appeared in the medical literature. Historians have reported that his cause of death was either related to a traumatic head injury he sustained in May of 1852 or from complications of alcoholic cirrhosis. In this manuscript, we will review Webster's medical history and autopsy to determine his cause of death.

RESUMEN

Background: In recent years, the online gambling market has rapidly developed, and betting has become one of the most popular forms of gambling. The aim of this study was to analyse the interest of the Malawian population in terms related to betting, sports betting, alcohol, cigarettes, and some psychoactive drugs through the relative search volumes of Google Trends. Methods: Internet search query data related to betting, sports betting, alcohol, cigarettes, and psychoactive drugs were obtained monthly from Google Trends for the period 2010-2022. Comparisons of interest levels in these topics were conducted in Malawi, and correlation coefficients were calculated. Results: In Malawi, relative search volumes for betting and sports betting terms were the highest (average RSVs: 66% and 30%). It was found that from 2019 onwards, the interest in betting and sports-related search topics and keywords increased significantly (p < 0.001). Strong positive correlations were found between betting-related keywords and alcohol and gross domestic product (r = 0.831 and r = 0.901, p < 0.001). A positive correlation was found between betting and psychoactive drug-related terms (minimum r = 0.417, p < 0.01). Conclusions: This study concludes that the interest of the Malawian population in betting has increased in recent years, while interest in psychoactive drugs and alcohol remains high. Gross domestic product is highly correlated with society's interest in betting. It was additionally found that Google Trends can be used as a tool to predict and monitor future risky behaviours, such as gambling disorder.

RESUMEN

OBJECTIVE: The aim of this article is to answer three relevant issues: i/What epileptic condition is referred to as subacute encephalopathy with seizures in alcoholics (SESA) syndrome; ii/ Why it can be important to distinguish SESA syndrome in clinical practice and iii/ What do we know about its pathophysiology. METHODS: We reviewed all cases published in the English language from the initial description of the syndrome to the present. All met the previously established criteria for SESA syndrome were included in our analysis. RESULTS: We found 34 patients diagnosed with SESA syndrome Fourteen (41.1%) out of 34 patients were over 60 years of age. In 12 (35.2 %), abstinence, and in 4 (11.7 %) excessive consumption of alcohol, were considered precipitating factors, respectively. Triggering causes were unknown in 18 cases (53.0 %). All cases (100 %) presented with altered mental status. Fourteen (41.1 %) subjects had a history of epileptic seizures in the context of alcohol withdrawal syndrome (AWS). Twenty (58.8 %) patients had focal motor seizures (FMSs), 24 (70.5 %) bilateral tonic-clonic seizures (BTCSs), and 15 (44.1 %) focal impaired awareness seizures (FIASs). In 8 (23.5 %), criteria for focal nonconvulsive status epilepticus (NCSE) were met. Twenty-eight (82.3 %) subjects had transient neurological deficits. In 29 (85.2 %) subjects, lateralized periodic discharges (LPDs) were observed on the EEG. Areas of signal hyperintensities and restricted diffusion in neuroimaging were mentioned in 22 subjects (64.7 %). Transfer to the intensive care unit was necessary in 8 (23.5 %) subjects. Thirteen (38.2 %) had recurrent episodes. Enduring brain damage was mentioned in 9 (26.4 %) cases. The most used anti-seizure medication (ASM) was levetiracetam, followed by phenytoin and lacosamide. CONCLUSIONS: SESA syndrome represents a well-defined subtype of focal NCSE in patients with chronic alcoholism. Its prompt recognition can facilitate the initiation of early ASM therapy and help design appropriate video-EEG evaluation and a treatment strategy.

RESUMEN

OBJECTIVE: Various patient placement criteria (PPC) have been developed to address alcohol use disorder (AUD), which has a high relapse rate and imposes substantial socioeconomic costs. Although research has shown PPC to be an effective tool, evidence supporting the Korean-PPC (K-PPC) is insufficient. This paper investigated whether treatment matching with the K-PPC was effective, based on variables related to AUD. METHODS: In total, 524 participants were evaluated using the 6 dimensions of the K-PPC and levels of care (LoC) were recommended based on the results. Participants whose treatment matched with the recommended LoC were classified into the matched group, and those whose treatment did not match were classified into the mismatched group. Subsequently, treatment was planned according to the determined LoC, and a total of 3 follow-up evaluations were conducted at 1 month, 3 months, and 6 months. RESULTS: There was no significant difference in the follow-up rate between the K-PPC matched group and the mismatched group. Of the variables measured by the 6 dimensions of the K-PPC, alcohol-related variables, depression, insight, and biomedical outcomes showed the most significant results (especially alcohol-related variables) from the baseline evaluation to the 6-month follow-up. In addition, the average adherence to the treatment program in the 6-month period was found to be higher in the matched group than in the mismatched group. CONCLUSION: The K-PPC could be effective for placing patients and providing treatment by matching patient characteristics. Enhancing treatment program retention can also have a positive effect on clinical outcomes.

RESUMEN

Alcohol, a toxic and psychoactive substance with addictive properties, severely impacts life quality, leading to significant health, societal, and economic consequences. Its rapid passage across the blood-brain barrier directly affects different brain cells, including astrocytes. Our recent findings revealed the involvement of pannexin-1 (Panx1) and connexin-43 (Cx43) hemichannels in ethanol-induced astrocyte dysfunction and death. However, whether ethanol influences mitochondrial function and morphology in astrocytes, and the potential role of hemichannels in this process remains poorly understood. Here, we found that ethanol reduced basal mitochondrial Ca2+ but exacerbated thapsigargin-induced mitochondrial Ca2+ dynamics in a concentration-dependent manner, as evidenced by Rhod-2 time-lapse recordings. Similarly, ethanol-treated astrocytes displayed increased mitochondrial superoxide production, as indicated by MitoSox labeling. These effects coincided with reduced mitochondrial membrane potential and increased mitochondrial fragmentation, as determined by MitoRed CMXRos and MitoGreen quantification, respectively. Crucially, inhibiting both Cx43 and Panx1 hemichannels effectively prevented all ethanol-induced mitochondrial abnormalities in astrocytes. We speculate that exacerbated hemichannel activity evoked by ethanol may impair intracellular Ca2+ homeostasis, stressing mitochondrial Ca2+ with potentially damaging consequences for mitochondrial fusion and fission dynamics and astroglial bioenergetics.

RESUMEN

Alcohol use disorder stands as a prevalent global issue, contributing to 140,000 annual deaths in the United States and causing numerous adverse health and socioeconomic outcomes. Despite being a natural physiological process, menopause often leads to troublesome symptoms that affect women's quality of life and exposes them to increased health risks. Our review delves into the intricate relationship between alcohol use disorder and the menopausal experience. We examine the impact of heightened alcohol consumption on the onset, severity, and burden of menopausal symptoms, particularly vasomotor symptoms. Additionally, we explore its effects on commonly experienced menopausal symptoms such as mood disturbances, sleep problems, and sexual dysfunction. Considering the chronic health conditions associated with both menopause and alcohol use disorder, our study also investigates the influence of alcohol use disorder on bone density. This is especially important due to the elevated risks and mortality linked to bone mineral density loss in menopausal women.

RESUMEN

BACKGROUND: Chronic alcoholism refers to the unpleasant symptoms directly resulting from excessive drinking. Increased alcohol metabolites and an unbalanced oxidative state are likely to blame for the reported effects under these circumstances. According to preclinical and clinical research, vitamin B12 can act on several organ systems with demonstrated neuroprotective, antioxidant, and glutamate modulating properties. OBJECTIVE: This research sought to examine the ameliorative effects of vitamin B12 (VtB12) in persistent alcohol (AlOH) exposed adult zebrafish with the help of following parameters like the anxiety related behavior test, Oxidative stress, and antioxidant assays, histological and immunofluorescence analysis. METHODS: Zebrafish pretreated with 0.40% AlOH (v/v) for 120 min (+AlOH) or not (-AlOH), were exposed for 6 h to home tank water (-VtB12) or to 59 µg-VtB12/kg-fish food (+VtB12) to analyze anxiety behavior in the geotaxis (novel tank) test as well as the oxidative brain damage in the adult zebrafish. RESULTS: Adult zebrafish exposed to chronic AlOH showed a decrease in the distance travelled, average and mobility speed, and increased the average frozen time, the explored area, and total no. of the site explored in the trapezoid tank. AlOH exposure also resulted in oxidative damage, enhanced lipid peroxidation, advanced oxidative protein products, decreased enzymatic and non-enzymatic antioxidant activities, and enhanced reactive oxygen species generation. Additionally, VtB12 supplementation improved neurogenesis, evident in increased Nissl cell numbers and NeuN expression in the brain. CONCLUSION: Chronic alcoholism may be effect on the brain cells as well as on the neuro-behavior of zebrafish. This research demonstrated that VtB12 shows promise as a neuroprotective agent against chronic alcoholism induced alterations in zebrafish's brain.

RESUMEN

BACKGROUND: The declaration of the COVID-19 pandemic led to public health restrictions that impacted the lives of people across the globe. Parents were particularly burdened with balancing multiple responsibilities, such as working from home while caring for and educating their children. Alcohol use among parents is an area that warrants further exploration. OBJECTIVE: This study aimed to investigate patterns of parental alcohol consumption during the COVID-19 pandemic, focusing on relative changes in the frequency and quantity of alcohol use compared to prepandemic use, nonparent adult samples, or both. METHODS: A scoping review informed by the methodology of Arksey and O'Malley explored patterns of parental alcohol consumption during the COVID-19 pandemic. Searches were conducted in CINAHL, Ovid MEDLINE, PsycINFO, and Web of Science. Search terms were created using the Joanna Briggs Institute framework of Population, Concept, and Context, with the population being parents and the concept being alcohol consumption during the COVID-19 pandemic. RESULTS: The database search yielded 3568 articles, which were screened for eligibility. Of the 3568 articles, 40 (1.12%) met the inclusion criteria and were included in the scoping review. Findings indicated the following: (1) having children at home was a factor associated with parental patterns of alcohol use; (2) mixed findings regarding gender-related patterns of alcohol consumption; and (3) linkages between parental patterns of alcohol use and mental health symptoms of stress, depression, and anxiety. CONCLUSIONS: This scoping review revealed heterogeneous patterns in parental alcohol use across sociocultural contexts during the COVID-19 pandemic. Given the known harms of alcohol use, it is worthwhile for clinicians to assess parental drinking patterns and initiate conversations regarding moderation in alcohol use.

RESUMEN

BACKGROUND: Ethanol elicits a rapid stimulatory effect and a subsequent, prolonged sedative response, which are potential predictors of EtOH consumption by decreasing adenosine signaling; this phenomenon also reflects the obvious sex difference. cAMP (cyclic Adenosine Monophosphate)-PKA (Protein Kinase A) signaling pathway modulation can influence the stimulatory and sedative effects induced by EtOH in mice. This study's objective is to clarify the role of phosphodiesterase (PDE) in mediating the observed sex differences in EtOH responsiveness between male and female animals. METHODS: EtOH was administered i.p. for 7 days to identify the changes in PDE isoforms in response to EtOH treatment. Additionally, EtOH consumption and preference of male and female C57BL/6J mice were assessed using the drinking-in-the-dark and 2-bottle choice tests. Further, pharmacological inhibition of PDE7A heterozygote knockout mice was performed to investigate its effects on EtOH-induced stimulation and sedation in both male and female mice. Finally, Western blotting analysis was performed to evaluate the alterations in cAMP-PKA/Epac2 pathways. RESULTS: EtOH administration resulted in an immediate upregulation in PDE7A expression in female mice, indicating a strong association between PDE7A and EtOH stimulation. Through the pharmacological inhibition of PDE7A KD mice, we have demonstrated for the first time, to our knowledge, that PDE7A selectively attenuates EtOH responsiveness and consumption exclusively in female mice, whichmay be associated with the cAMP-PKA/Epac2 pathway and downstream phosphorylation of CREB and ERK1/2. CONCLUSIONS: Inhibition or knockdown of PDE7A attenuates EtOH responsivenessand consumption exclusively in female mice, which is associated with alterations in the cAMP-PKA/Epac2 signaling pathways, thereby highlighting its potential as a novel therapeutic target for alcohol use disorder.

RESUMEN

PURPOSE: To describe four patients with subacute encephalopathy with seizures in alcoholics (SESA) syndrome and to review its clinical, electroencephalogram (EEG), neuroimaging and diagnostic criteria. METHODS: We conducted a retrospective analysis of a series of prospectively collected patients who met the previously established criteria for SESA syndrome. Subsequently, we reviewed all cases published in the English language from the initial description to the present. RESULTS: We found 34 patients diagnosed with SESA syndrome to date, including the four cases of SESA in this report. Fourteen out of 34 (41.1 %) patients were over 60 years of age. Twelve (35.2 %) were abstinent from alcohol and in 4 (11.7 %) there was excessive alcohol consumption. Triggering causes were unknown in 18 cases (53.0 %). All cases (100 %) presented with an altered mental status. Fourteen (41.1 %) subjects had a history of epileptic seizures in the context of acute withdrawal syndrome (AWS). Twenty (58.8 %) patients had focal motor seizures (FMSs), 24 (70.5 %) bilateral tonic-clonic seizures (BTCSs), and 15 (44.1 %) focal impaired awareness seizures (FIASs). In 8 (23.5 %), criteria for focal nonconvulsive status epilepticus (NCSE) were met. Twenty-eight (82.3 %) subjects had transient neurological deficits. In 29 (85.2 %) subjects, lateralized periodic discharges (LPDs) were observed in the EEG. Areas of increased T2/FLAIR signal and restricted diffusion were mentioned in 22 subjects (64.7 %). Transfer to the intensive care unit (ICU) was necessary in 8 (23.5 %) subjects. Thirteen (38.2 %) had recurrent episodes. Enduring cerebral sequelae had been mentioned in 9 (26.4 %) cases. The most used anti-seizure medication (ASM) was levetiracetam, followed by phenytoin and lacosamide. CONCLUSION: SESA syndrome represents a well-defined subtype of focal NCSE in patients with chronic alcoholism. Its prompt recognition can facilitate the initiation of early ASM therapy and help implement a video-EEG evaluation and neuroimaging strategy.

RESUMEN

BACKGROUND: The National Institute on Alcohol Abuse and Alcoholism (NIAAA) recommends the paper-based or computerized Alcohol Symptom Checklist to assess alcohol use disorder (AUD) symptoms in routine care when patients report high-risk drinking. However, it is unknown whether Alcohol Symptom Checklist response characteristics differ when it is administered online (eg, remotely via an online electronic health record [EHR] patient portal before an appointment) versus in clinic (eg, on paper after appointment check-in). OBJECTIVE: This study evaluated the psychometric performance of the Alcohol Symptom Checklist when completed online versus in clinic during routine clinical care. METHODS: This cross-sectional, psychometric study obtained EHR data from the Alcohol Symptom Checklist completed by adult patients from an integrated health system in Washington state. The sample included patients who had a primary care visit in 2021 at 1 of 32 primary care practices, were due for annual behavioral health screening, and reported high-risk drinking on the behavioral health screen (Alcohol Use Disorder Identification Test-Consumption score ≥7). After screening, patients with high-risk drinking were typically asked to complete the Alcohol Symptom Checklist-an 11-item questionnaire on which patients self-report whether they had experienced each of the 11 AUD criteria listed in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) over a past-year timeframe. Patients could complete the Alcohol Symptom Checklist online (eg, on a computer, smartphone, or tablet from any location) or in clinic (eg, on paper as part of the rooming process at clinical appointments). We examined sample and measurement characteristics and conducted differential item functioning analyses using item response theory to examine measurement consistency across these 2 assessment modalities. RESULTS: Among 3243 patients meeting eligibility criteria for this secondary analysis (2313/3243, 71% male; 2271/3243, 70% White; and 2014/3243, 62% non-Hispanic), 1640 (51%) completed the Alcohol Symptom Checklist online while 1603 (49%) completed it in clinic. Approximately 46% (752/1640) and 48% (764/1603) reported ≥2 AUD criteria (the threshold for AUD diagnosis) online and in clinic (P=.37), respectively. A small degree of differential item functioning was observed for 4 of 11 items. This differential item functioning produced only minimal impact on total scores used clinically to assess AUD severity, affecting total criteria count by a maximum of 0.13 criteria (on a scale ranging from 0 to 11). CONCLUSIONS: Completing the Alcohol Symptom Checklist online, typically prior to patient check-in, performed similarly to an in-clinic modality typically administered on paper by a medical assistant at the time of the appointment. Findings have implications for using online AUD symptom assessments to streamline workflows, reduce staff burden, reduce stigma, and potentially assess patients who do not receive in-person care. Whether modality of DSM-5 assessment of AUD differentially impacts treatment is unknown.

RESUMEN

The aim of this study was to evaluate the possible impact of the COVID-19 pandemic on prevalence rates and self-reported changes in patterns of alcohol use among first-year university students in Spain, considering the risk of problematic alcohol use. A serial cross-sectional study based on the uniHcos project was carried out. Data from 10 518 first-year university students (73.3% female, mean age 19 (SD = 1.6)) collected between 2012 and 2022 were analysed. The evolution of the pooled prevalence rates during the time series was analysed and the risk of problematic alcohol consumption was assessed using the AUDIT. Also, self-reported changes in alcohol use patterns during the pandemic were assessed. According to the results, during the COVID-19 pandemic, the prevalence of alcohol use in the past 30-days was reduced (76.3% in 2019 vs. 63.7% in COVID-19) increasing again in the New Normal period. Thus, a similar pattern in the practice of binge drinking was observed. Regarding the AUDIT score, 21.7% (95%CI 20.9, 22.6) of the students had harmful alcohol consumption, with a higher proportion among males. In the multivariable logistic models, a higher AUDIT score was significantly associated (p-value < 0.001) with being male and living with roommates. According to self-reported changes in consumption patterns during the COVID-19 pandemic, a higher proportion of participants with harmful use reported an increase in alcohol consumption compared to those at low-risk (43% vs 19%). Finally, despite the overall reduction in drinking prevalence during COVID-19, changes were not equal for all students and depended on their previous level of problematic drinking, highlighting that this should be considered in the development of strategies against alcohol use in this population.

RESUMEN

BACKGROUND: Alcohol Use Disorder (AUD) is linked to an attentional bias towards alcohol-related cues (e.g. images, smells), which acquire incentive properties and promote continued consumption. METHOD: We investigated how the general and alcohol attentional bias evolved longitudinally in AUD patients along two periods of abstinence: t = 0 (baseline, 1-3 months of abstinence) and t = 1 (follow-up; 6 months of abstinence), as well as their relationship with alcohol-related variables. General and alcohol-specific attentional bias were evaluated by the Classic and the Alcohol Stroop tests (neutral and alcohol conditions) in abstinent AUD patients and controls. RESULTS: At t = 0, the AUD group exhibited both general and alcohol-specific attentional biases, with greater effect in the general bias. At t = 1, alcohol-specific attentional bias decreased specifically in the AUD group and reached control levels (with interference index levels increasing from 1-3 months to 6 months). However, general attentional bias showed a trend toward improvement but it did not significantly change through abstinence process (linear mixed models, controlling for age, BMI, sex and education). CONCLUSIONS: In AUD patients, general and alcohol attentional biases exhibit different trajectories during abstinence, with the attentional bias toward alcohol improving significantly throughout this process whereas general attentional bias is maintained.

RESUMEN

OBJECTIVES: Type 2 diabetes (T2DM) and alcoholism are considered to be lifestyle-associated independent risk factors in fatty liver diseases (FLD) mediated cirrhosis and hepatocellular carcinoma (HCC). A combined effect of both these conditions may exacerbate the pathological changes and a pre-clinical exploration of this is expected to provide a mechanical detail of the pathophysiology. The present study aims to understand the effect of alcohol on pre- diabetic and type 2 diabetic female Wistar rats. METHODS: In this experimental study, 12 Wistar rats (180-220 g) were randomly assigned into three groups: Normal (fed normal rat chow), alcohol (20 %) fed diabetic (HFD + STZ), and pre-diabetic rats (HFD alone). After, two months of the experimental period, blood and liver tissues were collected lipid metabolic alteration, liver injury, and fibrosis were determined following biochemical and histological methods. Data were analyzed using one-way ANOVA and Dunnett's Post Hoc test. RESULTS: Significant dyslipidemia was observed in the liver tissues of diabetic and pre-diabetic rats following alcohol ingestion. A significant (p<0.05) increase in lipid peroxidation status, and hepatic marker enzyme activities (p<0.0001) were observed in diabetic animals. In corroborating with these observations, hematoxylin and eosin staining of hepatic tissue revealed the presence of sinusoidal dilation along with heavily damaged hepatocytes and inflammatory cell infiltration. Further, significantly (p<0.001) increased hepatic hydroxyproline content and extended picrosirius red stained areas of collagen in liver tissue indicated initiation of fibrosis in alcohol-fed diabetic rats. CONCLUSIONS: Overall, the results indicate that alcohol consumption in T2DM conditions is more deleterious than pre diabetic conditions in progressing to hepatic fibrosis.

RESUMEN

Multiple studies have demonstrated that acute ethanol consumption alters brain function and cognition. Nevertheless, the mechanisms underlying this phenomenon remain poorly understood. Astrocyte-mediated gliotransmission is crucial for hippocampal plasticity, and recently, the opening of hemichannels has been found to play a relevant role in this process. Hemichannels are plasma membrane channels composed of six connexins or seven pannexins, respectively, that oligomerize around a central pore. They serve as ionic and molecular exchange conduits between the cytoplasm and extracellular milieu, allowing the release of various paracrine substances, such as ATP, D-serine, and glutamate, and the entry of ions and other substances, such as Ca2+ and glucose. The persistent and exacerbated opening of hemichannels has been associated with the pathogenesis and progression of several brain diseases for at least three mechanisms. The uncontrolled activity of these channels could favor the collapse of ionic gradients and osmotic balance, the release of toxic levels of ATP or glutamate, cell swelling and plasma membrane breakdown and intracellular Ca2+ overload. Here, we evaluated whether acute ethanol exposure affects the activity of astrocyte hemichannels and the possible repercussions of this phenomenon on cytoplasmatic Ca2+ signaling and gliotransmitter release. Acute ethanol exposure triggered the rapid activation of connexin43 and pannexin1 hemichannels in astrocytes, as measured by time-lapse recordings of ethidium uptake. This heightened activity derived from a rapid rise in [Ca2+]i linked to extracellular Ca2+ influx and IP3-evoked Ca2+ release from intracellular Ca2+ stores. Relevantly, the acute ethanol-induced activation of hemichannels contributed to a persistent secondary increase in [Ca2+]i. The [Ca2+]i-dependent activation of hemichannels elicited by ethanol caused the increased release of ATP and glutamate in astroglial cultures and brain slices. Our findings offer fresh perspectives on the potential mechanisms behind acute alcohol-induced brain abnormalities and propose targeting connexin43 and pannexin1 hemichannels in astrocytes as a promising avenue to prevent deleterious consequences of alcohol consumption.
