Potential Link Between Exercise and N-Methyl-D-Aspartate Glutamate Receptors in Alcohol Use Disorder: Implications for Therapeutic Strategies. Psychol Res Behav Manag 2024; 17:2363-2376. [PMID: 38895648 PMCID: PMC11185169 DOI: 10.2147/prbm.s462403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Accepted: 05/16/2024] [Indexed: 06/21/2024] Open
Abstract
Alcohol use disorder (AUD) is a significant risk factor, accounting for approximately 13% of all deaths in the US. AUD not only destroys families but also causes economic losses due to reduced productivity, absenteeism, and healthcare expenses. Statistics revealing the sustained number of individuals affected by AUD over the years underscore the need for further understanding of the underlying pathophysiology to advance novel therapeutic strategies. Previous research has implicated the limbic brain regions N-methyl-D-aspartate glutamate receptors (NMDAR) in the emotional and behavioral effects of AUD. Given that aerobic exercise can modulate NMDAR activity and sensitivity to alcohol, this review presents a summary of clinical and basic science studies on NMDAR levels induced by alcohol consumption, as well as acute and protracted withdrawal, highlighting the potential role of aerobic exercise as an adjunctive therapy for AUD. Based on our findings, the utility of exercise in the modulation of reward-linked receptors and AUD may be mediated by its effects on NMDA signaling. These data support further consideration of the potential of aerobic exercise as a promising adjunctive therapy for AUD.

Replacing the Clinical Institute Withdrawal Assessment-Alcohol revised with the modified Richmond Agitation and Sedation Scale for alcohol withdrawal to support management of alcohol withdrawal symptoms: potential impact on length of stay and complications. CAN J EMERG MED 2024; 26:431-435. [PMID: 38796808 DOI: 10.1007/s43678-024-00710-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 04/27/2024] [Indexed: 05/29/2024]
Abstract
PURPOSE We evaluated impact on length of stay and possible complications of replacing the Clinical Institute Withdrawal Assessment-Alcohol Revised (CIWA-Ar) scale with a slightly modified Richmond Agitation and Sedation Scale (mRASS-AW) to support managing patients admitted with alcohol withdrawal symptoms in a community hospital. Since mRASS-AW is viewed as easier and quicker to use than CIWA-Ar, provided use of mRASS-AW does not worsen outcomes, it could be a safe alternative in a busy ED environment and offer an opportunity to release nursing time to care. METHODS Retrospective time-series analysis of mean quarterly length of stay. All analyses exclusively used our hospital's administrative discharge diagnoses database. During April 1st 2012 to December 14th 2014, the CIWA-Ar was used in the ED and in-patient units to guide benzodiazepine dosing decisions for alcohol withdrawal symptoms. After this point, CIWA-Ar was replaced with mRASS-AW. Data was evaluated until December 31st 2020. PRIMARY OUTCOME mean quarterly length of stay. SECONDARY OUTCOMES delirium, intensive care unit (ICU) admission, other post-admission complications, mortality. RESULTS N = 1073 patients. No association between length of stay and scale switch (slope change 0.3 (95% CI - 0.03 to 0.6), intercept change, 0.06 (- 0.03 to 0.2). CIWA-Ar (n = 317) mean quarterly length of stay, 5.7 days (95% 4.2-7.1), mRASS-AW (n = 756) 5.0 days (95% CI 4.3-5.6). Incidence of delirium, ICU admission or mortality was not different. However, incidence of other post-admission complications was higher with CIWA-Ar (6.6%) than mRASS-AW (3.4%) (p = 0.020). CONCLUSIONS This was the first study to compare patient outcomes associated with using mRASS-AW for alcohol withdrawal symptoms outside the ICU. Replacing CIWA-Ar with mRASS-AW did not worsen length of stay or complications. These findings provide some evidence that mRASS-AW could be considered an alternative to CIWA-Ar and potentially may provide an opportunity to release nursing time to care.

[PMID: 38800119 PMCID: PMC11127230 DOI: 10.1016/j.sopen.2024.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Accepted: 05/04/2024] [Indexed: 05/29/2024] Open
Abstract
Background Alcohol withdrawal syndrome (AWS) presents with a complex spectrum of clinical manifestations that complicate postoperative management. In trauma setting, subjective screening for AWS remains challenging due to the criticality of injury in these patients. We thus identified several patient characteristics and perioperative outcomes associated AWS development. Methods The 2016-2020 National Inpatient Sample was queried to identify all non-elective adult (≥18 years) hospitalizations for blunt or penetrating trauma undergoing operative management with a diagnosis of AWS. Patients with traumatic brain injury or with a hospital duration of stay <2 days were excluded. Outcomes of interest included in-hospital mortality, perioperative complications, hospitalization costs, length of stay (LOS) and non-home discharge. Results Of an estimated 2,965,079 operative trauma hospitalizations included for analysis, 36,415 (1.23 %) developed AWS following admission. The AWS cohort demonstrated increased odds of mortality (Adjusted Odds Ratio [AOR] 1.46, 95 % Confidence Interval [95 % CI] 1.23-1.73), along with infectious (AOR 1.73, 95 % CI 1.58-1.88), cardiac (AOR 1.24, 95 % CI 1.06-1.46), and respiratory (AOR 1.96, 95 % CI 1.81-2.11) complications. AWS was associated with prolonged LOS, (β: 3.3 days, 95 % CI: 3.0 to 3.5), greater cost (β: +$8900, 95 % CI $7900-9800) and incremental odds of nonhome discharge (AOR 1.43, 95 % CI 1.34-1.53). Furthermore, male sex, Medicaid insurance status, head injury and thoracic operation were linked with greater odds of development of AWS. Conclusion In the present study, AWS development was associated with increased odds of in-hospital mortality, perioperative complications, and resource burden. The identification of patient and operative characteristics linked with AWS may improve screening protocols in trauma care.

Shan HQ, Smith T, Klorig DC, Godwin DW. Protein kinase C epsilon-mediated modulation of T-type calcium channels underlies alcohol withdrawal hyperexcitability in the midline thalamus. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2024. [PMID: 38740544 DOI: 10.1111/acer.15342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 04/05/2024] [Accepted: 04/17/2024] [Indexed: 05/16/2024]
Abstract
BACKGROUND Millions of people struggle with alcohol use disorder (AUD). Abrupt abstinence after a period of chronic alcohol use can precipitate the alcohol withdrawal syndrome (AWS), which includes hyperexcitability and, potentially, seizures. We have shown that T-type Ca2+ channels are novel, sensitive targets of alcohol, an effect that is dependent upon protein kinase C (PKC). The purpose of this study was to (1) understand midline thalamic neuronal hyperexcitability during alcohol withdrawal and its dependence on PKC; (2) characterize T channel functional changes using both current clamp and voltage clamp methods; and (3) determine which PKC isoform may be responsible for alcohol withdrawal (WD) effects. METHODS Whole-cell patch clamp recordings were performed in midline thalamic neurons in brain slices prepared from C57bl/6 mice that underwent chronic intermittent alcohol exposure in a standard vapor chamber model. The recordings were compared to those from air-exposed controls. T-channel inactivation curves and burst responses were acquired through voltage-clamp and current-clamp recordings, respectively. RESULTS Whole-cell voltage clamp recordings of native T-type current exhibited a depolarizing shift in the voltage-dependency of inactivation during alcohol withdrawal compared to air-exposed controls. A PKCε translocation inhibitor peptide mitigated this change. Current clamp recordings demonstrated more spikes per burst during alcohol withdrawal. Consistent with voltage clamp findings, the PKCɛ translocation inhibitor peptide reduced the number of spikes per burst after WD. CONCLUSION We found that alcohol WD produces T channel-mediated hyperexcitability in the midline thalamus, produced in part by a shift in the inactivation curve consistent with greater availability of T current. WD effects on T current inactivation were reduced to control levels by blocking PKCε translocation. Our results demonstrate that PKCε translocation plays an important role in the regulation of alcohol withdrawal-induced hyperexcitability in midline thalamic circuitry.

Biochemical, Hematological, Inflammatory, and Gut Permeability Biomarkers in Patients with Alcohol Withdrawal Syndrome with and without Delirium Tremens. J Clin Med 2024; 13:2776. [PMID: 38792318 PMCID: PMC11121978 DOI: 10.3390/jcm13102776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 05/04/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
Background: Delirium Tremens (DT) is known to be a serious complication of alcohol withdrawal syndrome (AWS). Neurotransmitter abnormalities, inflammation, and increased permeability are associated with the pathogenesis of AWS and DT. However, the biomarkers of these conditions are still poorly understood. Methods: In this work, biochemical, hematologic, inflammatory, and gut permeability biomarkers were investigated in the following three groups: healthy controls (n = 75), severe AWS patients with DT (n = 28), and mild/moderate AWS without DT (n = 97). Blood sampling was performed after resolution of the acute condition (on 5 ± 1 day after admission) to collect clinical information from patients and to investigate associations with clinical scales. Biomarker analysis was performed using automated analyzers and ELISA. Inflammatory biomarkers included the erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hsCRP), and platelet-to-lymphocyte ratio (PLR). Results: Among the biochemical biomarkers, only glucose, total cholesterol, and alanine aminotransferase (ALT) changed significantly in the analyzed groups. A multiple regression analysis showed that age and ALT were independent predictors of the CIWA-Ar score. Hematologic biomarker analysis showed an increased white blood cell count, and the elevated size and greater size variability of red blood cells and platelets (MCV, RDWc, and PDWc) in two groups of patients. Gut permeability biomarkers (FABP2, LBP, and zonulin) did not change, but were associated with comorbid pathologies (alcohol liver disease and pancreatitis). The increase in inflammatory biomarkers (ESR and PLR) was more evident in AWS patients with DT. Cluster analysis confirmed the existence of a subgroup of patients with evidence of high inflammation, and such a subgroup was more frequent in DT patients. Conclusions: These findings contribute to the understanding of biomarker variability in AWS patients with and without DT and support the heterogeneity of patients by the level of inflammation.

Abstract
BACKGROUND AND OBJECTIVES The decision to initiate pharmacotherapy for alcohol withdrawal is typically based on examining self-reported use of alcohol and symptoms of withdrawal. Phosphatidylethanol (PEth) is a biomarker that could aim in clinical decision-making in withdrawal management. METHODS This report describes three cases highlighting the potential clinical utility of PEth in caring for individuals at risk for alcohol withdrawal. RESULTS Two of the cases received phenobarbital when their PEth showed that the risk of withdrawal was low and one case where PEth could have shown this was needed. The results were only available in a delayed fashion, however, could have been useful in informing clinical care. DISCUSSION AND CONCLUSION PEth can be a useful tool if available without delay. PEth can be used to quickly rule out alcohol withdrawal and avoid misdiagnoses and prolonged hospital stays. SCIENTIFIC SIGNIFICANCE This is a clinical case study available looking at PEth and withdrawal in hospitalized patients. It proposes that PEth can be used as a way to quickly rule out alcohol withdrawal to avoid misdiagnoses and the possibility of a prolonged hospital stay.

Abstract
Excessive and uncontrolled consumption of alcohol can cause alcohol use disorder (AUD), but its pharmacological mechanisms are not fully understood. Inhibiting the reverse mode activity of the sodium-calcium exchanger (NCX) can reduce the risk of alcohol withdrawal seizures, suggesting that NCX could play a role in controlling alcohol consumption. Here, we investigated how two potent inhibitors of NCX reverse mode activity, SN-6 (NCX1) and KB-R7943 (NCX3), affect voluntary alcohol consumption in adult male and female rats using the intermittent alcohol access two-bottle choice paradigm. Initially, animals were trained to drink 7.5% ethanol and water for four weeks before administering SN-6 and KB-R7934. Afterward, their alcohol intake, preference, and water intake were recorded 2 and 24 h after exposure to water and 7.5% ethanol. SN-6 significantly reduced alcohol consumption by 48% in male and 36% in female rats without affecting their water intake. Additionally, SN-6 significantly reduced alcohol preference in females by 27%. However, KB-R7943 reduced alcohol consumption by 42% in female rats and did not affect alcohol preference or water intake. These findings suggest that alcohol exposure increased NCX reverse activity, and targeting NCX1 could be an effective strategy for reducing alcohol consumption in subjects susceptible to withdrawal seizures.

Abstract
Delirium tremens (DT) is a severe condition resulting from alcohol withdrawal. This review highlights the challenges in diagnosing and managing DT and emphasizes the importance of early recognition and intervention to prevent complications and ensure optimal patient outcomes. The discussion of the pathophysiology of DT, focusing on the neurochemical imbalances involving the neurotransmitters gamma-aminobutyric acid and glutamate, explains how chronic alcohol dependence leads to these imbalances and contributes to the hyperexcitability seen in DT. The management of DT involves ensuring patient safety and alleviating symptoms, primarily through pharmacological approaches, such as benzodiazepines. Closely monitoring vital signs and electrolyte imbalances is necessary due to autonomic dysregulation associated with DT. The mention of the potential complexity of DT when coexisting with other conditions emphasizes the need for additional research to advance comprehension, identify predictive factors, and enhance its management.

Abstract
OBJECTIVE Alcohol-related seizures (ARS) are one of the most important consequences of alcohol withdrawal syndrome (AWS). However, demographic and clinical characteristics, and furthermore, the relationship of ARS with delirium tremens (DT), have not yet been evaluated in detail. Therefore, the aim of the present study was to reveal the correlates of ARS and examine the interaction of ARS with the occurrence of DT and with the severity of AWS. METHODS In the retrospective study (Study 1) 2851 medical charts of inpatient admissions characterized by AWS and DT were listed. Demographic and clinical variables of ARS were assessed. In the follow-up study (Study 2), patients admitted with AWS without (N = 28) and with (N = 18) ARS were enrolled. Study 1 was performed between 2008 and 2023, and Study 2 was performed in 2019 in Hungary. To determine the severity of AWS, the Clinical Institute Withdrawal Assessment Scale for Alcohol, Revised (CIWA-Ar) was used. ARS is a provoked, occasional seizure; therefore, patients with epilepsy syndrome were excluded from the two studies. Statistical analyses were performed by the means of chi-square tests, multinomial logistic regressions, mixed ANOVA, and derivation. RESULTS The occurrence of DT, the history of ARS, and somatic co-morbidities were found to be risk factors for the appearance of ARS. ARS was proved to be a risk factor for the development of DT. In the follow-up study, there was no difference in the decrease of CIWA-Ar scores between the groups. SIGNIFICANCE Our present findings support the likelihood of kindling, which is one of the most important mechanisms underlying the development of ARS, but do not directly prove its presence. Additionally, our results revealed that the severity of AWS is not influenced by the presence of ARS. PLAIN LANGUAGE SUMMARY Provoked, occasional seizures during AWS are defined as ARS. In the present study, predictors and interactions of these seizures with DT-the most severe form of withdrawal-and with the severity of withdrawal were examined in retrospective and follow-up studies. The present study shows that a history of withdrawal seizures, the occurrence of DT, and somatic comorbidities are predictors of the development of seizures. Furthermore, our findings suggest that the presence of seizures does not influence the severity of withdrawal.

Impulsivity and aggression in alcohol withdrawal syndrome is modulated by the interaction of ZNF804A and mTOR polymorphism. Pharmacol Biochem Behav 2024; 236:173708.

Abstract
Alcohol withdrawal syndrome (AWS) is a poorly studied phenotype of alcohol use disorder. Understanding the relationship between allelic interactions and AWS-related impulsivity and aggression could have significant implications. This study aimed to investigate the main and interacting effects of ZNF804A and mTOR on impulsivity and aggression during alcohol withdrawal. 446 Chinese Han adult males with alcohol dependence were included in the study. Impulsivity and aggression were assessed, and genomic DNA was genotyped. Single gene analysis showed that ZNF804A rs1344706 (A allele/CC homozygote) and mTOR rs1057079 (C allele/TT homozygote) were strongly associated with AWS-related impulsivity and aggression. In the allelic group, MANOVA revealed a significant gene x gene interaction, suggesting that risk varied systematically depending on both ZNF804A and mTOR alleles. Additionally, a significant interactive effect of ZNF804A rs1344706 and mTOR rs7525957 was found on motor impulsivity and physical aggression, and the ZNF804A rs1344706 gene variant had significant effects on motor impulsivity and physical aggression only in mTOR rs7525957 TT homozygous carriers. The study showed that specific allelic combinations of ZNF804A and mTOR may have protective or risk-enhancing effects on AWS-related impulsivity and aggression.

Abstract
Binge alcohol consumption is a major risk factor for developing Alcohol Use Disorder (AUD) and is associated with alcohol-related problems like accidental injury, acute alcohol poisoning, and black-outs. While there are numerous brain regions that have been shown to play a role in this AUD in humans and animal models, the central nucleus of the amygdala (CeA) has emerged as a critically important locus mediating binge alcohol consumption. In this study, we sought to understand how relative gene expression of key signaling molecules in the CeA changes during different periods of abstinence following bouts of binge drinking. To test this, we performed drinking in the dark (DID) on two separate cohorts of C57BL/6J mice and collected CeA brain tissue at one day (acute) and 7 days (protracted) abstinence after DID. We used qRTPCR to evaluate relative gene expression changes of 25 distinct genes of interest related to G protein-coupled receptors (GPCRs), neuropeptides, ion channel subunits, and enzymes that have been previously implicated in AUD. Our findings show that during acute abstinence CeA punches collected from female mice had upregulated relative mRNA expression of the gamma-aminobutyric acid receptor subunit alpha 2 (Gabra2), and the peptidase, angiotensinase c (Prcp). CeA punches from male mice at the same time point in abstinence had upregulated relative mRNA encoding for neuropeptide-related molecules, neuropeptide Y (Npy) and somatostatin (Sst), as well as the neuropeptide Y receptor Y2 (Npyr2) but downregulated, Glutamate ionotropic receptor NMDA type subunit 1 (Grin1). After protracted abstinence CeA punches collected from female mice had increased mRNA expression of corticotropin releasing hormone (Crh) and Npy. While CeA punches collected from male mice at the same timepoint had upregulated relative mRNA expression of Npy2r and downregulated mRNA expression of Gabra2, Grin1 and opioid receptor kappa 1 (Oprk1). Our findings support that there are differences in how the CeA of male and female respond to binge-alcohol exposure, highlighting the need to understand the implications of such differences in the context of AUD and binge drinking behavior.

Abstract
Physiologic and psychological effects of substance use are common occurrences. They may be the proximate purpose of the exposure or related to an unintended complication. Acute short-term exposure effects may not be the same as long-term effects. These effects are mediated by different receptors they act on and the homeostatic changes that occur due to repeat exposure. We review in this article the physiologic and psychological effects from exposure to commonly encountered drugs, ethanol, sedative hypnotics, cocaine, amphetamines, marijuana, opioids, nicotine, hydrocarbons (halogenated and non-halogenated), and nitrous oxide.

Neuropharmacology 2023; 240:109694. [PMID: 37659439 PMCID: PMC11094430 DOI: 10.1016/j.neuropharm.2023.109694] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 08/29/2023] [Accepted: 08/29/2023] [Indexed: 09/04/2023]
Abstract
Environmental conditioning factors have a profound impact on alcohol-seeking behavior and the maintenance of alcohol use in individuals with alcohol dependence. Cues associated with alcohol, depending on the perceived value of the primary reinforcer, gain salience and can trigger relapse. This study investigates the correlation between the reward magnitude of the primary reinforcer and the reinstatement evoked by cues predictive of their availability in male rats. Rat self-administration procedures were used to test reinstatement, with reinforcers consisting of 10% alcohol, 10% sucrose, or 2% sodium chloride (NaCl) experienced under need-state conditions. The effect of MTEP ([(2-methyl-1,3-thiazol-4-yl) ethynyl] pyridine), a selective metabotropic glutamate receptor 5 (mGluR5) antagonist, on motivation and reinstatement behaviors was also evaluated. RESULTS: demonstrate that under Fixed Ratio 1 (FR1) schedule, the three reinforcers maintain operant responding with the following order of magnitude 10% sucrose >2% NaCl >10% alcohol > water. Under a progressive ratio (PR) schedule of reinforcement, rats exhibit a significantly higher breakpoint for 2% NaCl (under Na-depletion), followed by 10% sucrose and 10% alcohol. After extinction, a significant reinstatement is observed with the magnitude order of 10% sucrose >10% alcohol >2% NaCl. However, only re-exposure to alcohol-paired cues induced significant reinstatement of alcohol-seeking after 4 and 8 months. Treatment with MTEP significantly reduces reinstatement of responding across all reinforcers, with the strongest effect observed on alcohol-seeking. These findings suggest that mGluR5 plays a general role in controlling cue-reactivity, but the effect is prominent in the case of alcohol compared to natural rewards. In conclusion, the results demonstrate a remarkable dissociation between the rewarding magnitude of the primary reinforcer and its ability to trigger relapse upon presentation of a cue previously associated with it. Importantly, alcohol, despite having lower intrinsic motivational value compared to a natural reward (sucrose) or a consummatory stimulus experienced under need state conditions (NaCl), can elicit more robust and longer-term reinstatement of seeking responses. Finally, our data demonstrate a significant involvement of the mGluR5 system in the regulation of seeking behavior.

Abstract
BACKGROUND AND AIMS Little is known about long-term consequences of delirium tremens (DT). This study aimed to compare all-cause and cause-specific mortality and alcohol-related morbidity between patients with: (i) DT, (ii) alcohol withdrawal state (AWS) and (iii) alcohol dependence (AD). DESIGN A national longitudinal health registry study with linked data from the Norwegian Patient Registry and the Norwegian Cause of Death Registry. SETTING Norway. PARTICIPANTS All patients registered in the Norwegian Patient Registry between 2009 and 2015 with a diagnosis of AD (ICD-10 code F10.2), AWS (F10.3) or DT (F10.4) and aged 20-79 years were included (n = 36 287). MEASUREMENTS Patients were categorized into three mutually exclusive groups; those with DT diagnosis were categorized as DT patients regardless of whether or not they had received another alcohol use disorder diagnosis during the observation period or not. Outcome measures were: annual mortality rate, standardized mortality ratios (SMR) for all-cause and cause-specific mortality and proportion of alcohol-related morbidities which were registered in the period from 2 years before to 1 year after the index diagnosis. FINDINGS DT patients had higher annual mortality rate (8.0%) than AWS (5.0%) and AD (3.6%) patients, respectively. DT patients had higher mortality [SMR = 9.8, 95% confidence interval (CI) = 8.9-10.7] than AD patients (SMR = 7.0, 95% CI = 6.8-7.2) and AWS patients (SMR = 7.8, 95% CI = 7.2-8.4). SMR was particularly elevated for unnatural causes of death, and more so for DT patients (SMR = 26.9, 95% CI = 21.7-33.4) than for AD patients (SMR = 15.2, 95% CI = 14.2-16.3) or AWS patients (SMR = 20.1, 95% CI = 16.9-23.9). For all comorbidities, we observed a higher proportion among DT patients than among AWS or AD patients (P < 0.001). CONCLUSIONS People treated for delirium tremens appear to have higher rates of mortality and comorbidity than people with other alcohol use disorders.

Abstract
Alcohol use disorders (AUDs) are prevalent in intensive care units (ICUs). Alcohol abuse and/or dependence, leading to alcohol withdrawal syndrome (AWS), is as high as 10% or more. There seem to be wide variations in management strategies used to manage these patients, prompting an evaluation of the knowledge gap as well as finding the barriers. Noting lack of such literature in the Indian setting, a survey is undertaken to evaluate practice patterns surrounding the identification and management of alcohol dependence/abuse and AWS in the Indian critical care scenario. The main respondents of the survey are independent practitioners with anesthesia as their base specialty and overwhelmingly practice in multidisciplinary ICUs. They estimated AUD prevalence to be under 10%. The reason most expressed for lack of AUD documentation is fear of insurance rejection. Very few used risk assessment tool in evaluation of AUDs and AWS. Awareness of ICD 10/DSM-V components of AWS diagnosis was negligible. Chlordiazepoxide and lorazepam were used either in a fixed- or symptom-based therapy. Compared to available literature, haloperidol use is excessive, while barbiturates rarely. The wide variation is seen with the dose and frequency of thiamine in AWS without neurological complications. The impact on mortality and morbidity is poorly understood. In conclusion, the survey reported a lower prevalence compared to international literature. Insurance rejection is one of the main factors in limiting adequate history taking or documenting AUDs. Alcohol withdrawal syndrome risk assessment, monitoring, and management is variable and suboptimal. Variability in all aspects of AUDs is attributable to the knowledge gap. Further studies are needed to bridge the research gap. How to cite this article Gopaldas JA, Padyana M, Rai PP.

Abstract
Patients with alcohol use disorders are commonly identified and managed in the emergency department. Although the alcohol-intoxicated patient has a high risk for significant injury and diseases, the majority will be allowed to sober in the emergency department and can be discharged without incident. However, there are metabolic derangements in these patients, such as alcoholic ketoacidosis, Wernicke-Korsakoff, and potomania that very commonly present similar to intoxication and can be misdiagnosed by emergency clinicians.

Abstract
Alcohol is one of the most widely used substances. Alcohol use accounts for 5.1% of the global disease burden, contributes substantially to societal and economic costs, and leads to approximately 3 million global deaths yearly. Alcohol use disorder (AUD) includes various drinking behavior patterns that lead to short-term or long-lasting effects on health. Ethanol, the main psychoactive molecule acting in alcoholic beverages, directly impacts the GABAergic system, contributing to GABAergic dysregulations that vary depending on the intensity and duration of alcohol consumption. A small number of interventions have been developed that target the GABAergic system, but there are promising future therapeutic avenues to explore. This review provides an overview of the impact of alcohol on the GABAergic system, the current interventions available for AUD that target the GABAergic system, and the novel interventions being explored that in the future could be included among first-line therapies for the treatment of AUD.

Abstract
OBJECTIVE Review dexmedetomidine use in critically ill patients for niche indications including sleep, delirium, alcohol withdrawal, sepsis, and immunomodulation. DATA SOURCES Literature was sought using PubMed (February 2012-November 2022). Search terms included dexmedetomidine AND (hypnotics OR sedatives OR sleep OR delirium OR immunomodulation OR sepsis OR alcohol withdrawal). STUDY SELECTION AND DATA EXTRACTION Relevant studies conducted in humans ≥18 years published in English were included. Exclusion criteria included systematic reviews, meta-analyses, and studies evaluating oral dexmedetomidine or other alpha-2 agonists. DATA SYNTHESIS A total of 231 articles were retrieved. After removal of duplicates, title and abstract screening, and application of inclusion criteria, 35 articles were included. Across the clinical conditions included in this review, varying clinical outcomes were seen. Dexmedetomidine may improve morbidity outcomes in delirium, sleep, and alcohol withdrawal syndrome. Due to limited human studies and poor quality of evidence, no conclusions can be drawn regarding the role of dexmedetomidine in immunomodulation or sepsis. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE This review presents data for potential niche roles of dexmedetomidine aside from sedation in critically ill patients. This may serve as a guide for sedation selection in critically ill patients who may also benefit from the pleiotropic effects of dexmedetomidine due to a clinical condition discussed in this review. CONCLUSION While further studies are needed, dexmedetomidine may provide benefit in other indications in critically ill patients including delirium, sleep, and alcohol withdrawal. Given the poor quality of evidence of dexmedetomidine use in immunomodulation and sepsis, no conclusions can be drawn.

Predictors of Escalation to Intensive Care Unit Level of Care Among Admissions for Alcohol Withdrawal. J Community Hosp Intern Med Perspect 2023; 13:8-14. [PMID: 37868680 PMCID: PMC10589036 DOI: 10.55729/2000-9666.1241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 06/16/2023] [Accepted: 07/05/2023] [Indexed: 10/24/2023] Open
Abstract
According to the 2019 National Survey on Drug Use and Health, 14.5 million people ages 12 and older had alcohol abuse disorder. Alcohol withdrawal syndrome (AWS) can be defined as a collection of physical symptoms experienced due to abrupt cessation of alcohol after long-term dependence. In instances where regular inpatient management fails to control AWS symptoms, patients are shifted to intensive care units (ICUs) for closer monitoring and prevention of life-threatening complications like withdrawal seizures and delirium tremens (DTs), labeled as severe alcohol withdrawal syndrome (SAWS). Although this represents a significant healthcare burden, minimal studies have been conducted to determine objective predictors. In this study, we aim to determine the effect of patient demographics, socio-economic status, biochemical parameters, and clinical factors on the need for escalation to ICU level of care among admissions for AWS. Our study showed that factors such as a history of DTs or alcohol-related seizures, the initial protocol of management, degree of reported alcohol usage, activation of rapid response teams, mean corpuscular value, alcohol level on admission, highest Clinical Institute Withdrawal Assessment Alcohol Revised (CIWA-Ar) scored during the hospital stay, and the total amount of sedatives used were significantly associated with escalation to ICU level of care. Clinicians must use these objective parameters to identify high-risk patients and intervene early. We encourage further studies to establish a scoring algorithm incorporating biochemical parameters to tailor management algorithms that might better suit high-risk patients.

Abstract
PURPOSE To compare the efficacy and safety of non-benzodiazepines (non-BZDs) to benzodiazepines (BZDs) in the treatment of alcohol withdrawal syndrome (AWS). METHODS For relevant literature, Google Scholar, PubMed, Embase, OVID MEDLINE, EBSCO, Cochrane Central Registry of Controlled Trials, Web of Science, and Scopus were searched. Randomized control trials (RCTs) were included, omitted were nonblinded trials, blinded trials that were not randomized, and open-label studies. The Effective Public Health Practice Project Quality Assessment was used to assess the trial's quality. A meta-analysis and a narrative synthesis were carried out. RESULTS Twenty non-BZDs and five BZDs were investigated in thirty RCTs. Meta-analysis favored gabapentin over chlordiazepoxide and lorazepam (d = 0.563, p < 0.001) and carbamazepine over oxazepam and lorazepam (d = 0.376, p = 0.029), for reducing Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scale scores. Eleven non-BZDs fared better than BZDs for reducing CIWA-Ar, Total Severity Assessment, Selective Severity Assessment, Borg and Weinholdt, and Gross Rating Scale for Alcohol Withdrawal scores. Eight non-BZDs outmatched BZDs regarding autonomic, motor, awareness, and psychiatric symptoms. Sedation and fatigue were prevalent in BZDs, while seizures were prevalent in non-BZDs. CONCLUSION For AWS treatments, non-BZDs are superior to or equally effective as BZDs. Non-BZD adverse events warrant further investigation. Agents that inhibit gated ion channels are promising candidates. PROTOCOL REGISTRATION PROSPERO CRD42022384875.

Harm Reduct J 2023; 20:93.

Abstract
Despite high rates of harm attributable to alcohol use itself and the associated marginalization of illicit drinkers in Vancouver's Downtown Eastside (DTES), alcohol-specific harm reduction services there are under-resourced and highly disconnected from one another. In response to these conditions and high rates of death amongst its membership, the Eastside Illicit Drinkers Group for Education, an affiliate group of the Vancouver Area Network of Drug Users, convened a regular meeting of stakeholders, termed a "community of practice" in 2019 to bring together peers who used beverage and non-beverage alcohol, shelter and harm reduction service providers, public health professionals, clinicians, and policymakers to improve system-level capacity to reduce alcohol-related harm. The discussions that followed from these meetings were transformed into the Vancouver Alcohol Strategy (VAS), a comprehensive, harm reduction-oriented policy framework for alcohol harm reduction in the DTES. This article highlights our experiences producing community-led alcohol policy through the VAS with specific attention to the ways in which people who use alcohol themselves were centred throughout the policy development process. We also provide summary overviews of each of the VAS document's 6 thematic areas for action, highlighting a sampling of the 47 total unique recommendations. Historically, people who use non-beverage alcohol and whose use of alcohol in public spaces is criminalized due to housing precarity and visible poverty have been excluded from the development of population-level alcohol policies that can harm this specific population. The process of policy development undertaken by the VAS has attempted to resist this top-down approach to public health policy development related to alcohol control by intentionally creating space for people with lived experience to guide our recommendations. We conclude by suggesting that a grassroots enthusiasm for harm reduction focused policy development exists in Vancouver's DTES, and requires resources from governmental public health institutions to meaningfully prevent and reduce alcohol-related and policy-induced harms.

Abstract
BACKGROUND The management of epilepsy includes appropriate antiseizure medication (ASM) treatment and careful avoidance of seizure precipitating factors. Seizure precipitants may be multiple occurring with low intensity adding to each other, thus leaving essential elements unrecognized. The aim of this study was to reveal the patients' subjective perceptions of the most important factors and to compare them with standardized measurements. METHODS The study included 152 acute hospital admissions for seizures. The patients were asked to score the impact of various seizure precipitants as perceived by themselves on a visual analogue scale (VAS). The following items related to seizure occurrence were quantified: sleep deprivation by sleep diaries, ASM adherence by therapeutic drug monitoring, the Alcohol Use Identification Test, and the Hospital Anxiety and Depression Scale. Statistical analyses, including multiple regression, were performed to discover relationships between various parameters. RESULTS The interaction of the various factors was high. The association between lack of sleep and hazardous drinking and anxiety was highly significant. Perceived stress correlated well with anxiety and depression. Relatively low VAS scores for missed medication in patients with identified non-adherence suggest that insufficient patient awareness is common. Low VAS-scores for alcohol in patients with harmful drinking also suggest low acknowledgment of alcohol-related seizures. High alcohol scores were associated with sleep deprivation, anxiety and depression. CONCLUSION The circumstances leading to an epileptic seizure are complex. Stress, sleep loss, alcohol intake, and missed medication are among the most commonly reported seizure precipitants. They are often combined, and various facets of the same underlying cause may be at play. Their sequence and relative impact are often difficult to establish. Improved understanding of the cascade of events preceding a seizure can improve comprehensive personalized management of uncontrolled epilepsy.

Abstract
Many previous studies have discussed an association between alcohol use disorder (AUD) and seizure incidents. There are also case reports of seizures during opioid withdrawals. Therefore, it is possible that AUD patients may have a higher risk of seizures if they also have opioid use disorder (OUD). However, it remains unproven whether AUD patients with a dual diagnosis of OUD have higher seizure incidents, to our knowledge. This study explored seizure incidents among the patients with a dual diagnosis of AUD and OUD as well as seizures among AUD only or OUD only patients. This study utilized de-identified data from 30 777 928 hospital inpatient encounters at 948 healthcare systems over 4 years (9/1/2018-8/31/2022) from the Vizient® Clinical Database for this study. Applying the International Classification of Diseases 10th Revision (ICD-10) diagnostic codes, AUD (1 953 575), OUD (768 982), and seizure (1 209 471) encounters were retrieved from the database to examine the effects of OUD on seizure incidence among AUD patients. This study also stratified patient encounters for demographic factors such as gender, age, and race, as well as the Vizient-categorized primary payer. Greatest gender differences were identified among AUD followed by OUD, and seizure patient groups. The mean age for seizure incidents was 57.6 years, while that of AUD was 54.7 years, and OUD 48.9 years. The greatest proportion of patients in all 3 groups were White, followed by Black, with Medicare being the most common primary payer in all 3 categories. Seizure incidents were statistically more common (P < .001, chi-square) in patients with a dual diagnosis of AUD and OUD (8.07%) compared to those with AUD only (7.55%). The patients with the dual diagnosis had a higher odd ratio than those with AUD only or OUD only. These findings across more than 900 health systems provide a greater understanding of seizure risks. Consequently, this information may help in triaging AUD and OUD patients in certain higher-risk demographic groups.

Abstract
We report a case of posterior reversible encephalopathy syndrome (PRES) during treatment for alcohol withdrawal syndrome with gabapentin and clonidine. The patient developed severe hypertension, confusion and tremor, culminating in bilateral vision loss and a seizure. Imaging revealed posterior cerebral edema. Treatment with benzodiazepines, antihypertensives, and anti-seizure medications led to resolution. One year later, imaging showed resolution of the findings. We review the associated literature and propose the recognition of a PRES sub-entity, Alcohol-Related PRES (ARPRES), which can appear in the setting of alcohol withdrawal syndrome, chronic alcohol use, and acute alcohol intoxication, with or without hypertension.

Abstract
Alcohol withdrawal (AW) is a feature of alcohol use disorder that may occur in up to half of individuals with chronic, heavy alcohol consumption whenever alcohol use is abruptly stopped or significantly reduced. To date, few genes have been robustly associated with AW; this may be partly due to most studies defining AW as a binary construct despite the multiple symptoms and their range in severity from mild to severe. The current study examined the effects of genome-wide loci on a factor score for AW in high risk and community family samples in the Collaborative Study for the Genetics of Alcoholism (COGA). In addition, we tested whether differentially expressed genes associated with alcohol withdrawal in model organisms are enriched in human genome-wide association study (GWAS) effects. Analyses employed roughly equal numbers of males and females (mean age 35, standard deviation = 15; total N = 8009) and included individuals from multiple ancestral backgrounds. Genomic data were imputed to the HRC reference panel and underwent strict quality control procedures using Plink2. Analyses controlled for age, sex, and population stratification effects using ancestral principal components. We found support that AW is a polygenic disease (SNP-heritability = 0.08 [95 % CI = 0.01, 0.15; pedigree-based heritability = 0.12 [0.08,0.16]. We identified five single nucleotide variants that met genomewide significance, some of which have previously been associated with alcohol phenotypes. Gene-level analyses suggest a role for COL19A1 in AW; H-MAGMA analyses implicated 12 genes associated with AW. Cross-species enrichment analyses indicated that variation within genes identified in model organism studies explained <1 % of the phenotypic variability in human AW. Notably, the surrounding regulatory regions of model organism genes explained more variance than expected by chance, indicating that these regulatory regions and gene sets may be important for human AW. Lastly, when comparing the overlap in genes identified from the human GWAS and H-MAGMA analyses with the genes identified from the animal studies, there was modest overlap, indicating some convergence between the methods and organisms.

Abstract
Ethanol remains one of the most frequently abused agents by adolescents, exceeding all others except for vaping nicotine, and use is rising. With increased ethanol use comes a greater risk for dependence and potential for alcohol withdrawal syndromes (AWS). Pediatric AWS is extremely rare and poorly characterized in the literature. Pediatric acute care practitioners may have limited exposure to AWS. We report the case of a 16-year-old male with a history of polysubstance abuse who presented with mild AWS and progressed rapidly to delirium tremens. His withdrawal was initially refractory to high dose benzodiazepine therapy but responded well to phenobarbital. This case highlights how rapidly and dangerously AWS can progress if not aggressively treated. Given the rise in adolescent alcohol use and potential for life threatening symptoms, practitioners, especially in acute care specialties such as emergency medicine, critical care, and hospital medicine, would benefit from additional familiarity with AWS diagnoses and management strategies.

Abstract
We assessed the efficacy and safety of PB compared with benzodiazepine (BZD)-based protocols in treating AWS in MICU. DESIGN Single-center, pre-post protocol implementation study. SETTING The setting is a forty-bed MICU in a tertiary-level academic medical center. PATIENTS We included all patients admitted to the MICU with a primary diagnosis of AWS. INTERVENTIONS Intravenous PB 260 mg followed by 130-mg doses every 15-30 minutes as needed up to 15 mg/kg of ideal body weight versus escalating doses of BZD, to achieve a Clinical Institute Withdrawal Assessment Alcohol Scale-Revised score less than 10. MEASUREMENTS AND MAIN RESULTS ICU and hospital length of stay (LOS), in addition to safety measures were the main outcomes of the study. A total of 102 patients were included, 51 in the PB arm and 51 in the BZD arm. There were no differences in baseline clinical characteristics. Half the patients in each group were admitted with delirium tremens. The use of PB-based protocol was associated with 35% reduction in median ICU LOS (1.5 d [interquartile range, 1.2-2.4 d] vs 2.3 d [1.4-4.8 d]; p = 0.009) and 50% reduction in hospital LOS (3 d [2.7-4 d] vs 6 d [4-10 d]; p < 0.001). After adjustment for comorbidities and clinical factors, PB protocol decreased ICU LOS days by 40% (95% CI; 25.8-53.5%). PB group required fewer adjunctive medications to control symptoms (0.7 [0.5-1] vs 2.5 [2-3]; p < 0.001), less need for intubation (1/51 [2%] vs 10/10 [19.6%]; p = 0.023) and less need for physical restraint (19/51 [37.3%] vs 29/51 [56.9%]; p = 0.047), compared with the BZD group. CONCLUSIONS A protocol utilizing rapidly escalating doses of PB over a short period is an effective and safe alternative to BZD in treating AWS in MICU.

Abstract
BACKGROUND Delirium tremens (DT) is a common complication of alcohol withdrawal. Pharmacological treatment of hospitalized patients with DT is important in addiction medicine but also in other medical disciplines where DT can occur as a complication of hospitalization. Patients suffering from DT require treatment with benzodiazepines (short-acting benzodiazepines for elderly patients to reduce accumulation), and in cases of psychotic symptoms, treatment with antipsychotics. Benzodiazepines are a first-line treatment for DT. A specific guideline for the use of antipsychotics has yet to be developed. This review discusses the current guidelines and literature on the antipsychotic treatment options in DT. AIM Systematic presentation of relevant antipsychotics for the treatment of DT. METHODS A systematic literature search was conducted using Scopus and PubMed. The last search was conducted on May 22nd 2022. Original articles and reviews on antipsychotic treatment in alcohol withdrawal and DT were included in this review. Further, international guidelines were also considered. The review was registered using the PROSPERO database (https://www.crd.york.ac.uk/prospero/); CRD42021264611. RESULTS Haloperidol is mainly recommended for use in the intensive care unit. There is little literature on the use of atypical antipsychotics to treat DT. Treatment with antipsychotics always should be combined with benzodiazepines, and physicians should watch out for complications like neuroleptic malignant syndrome, QTc interval prolongation, extrapyramidal symptoms and withdrawal seizures resulting from lowering the threshold for seizures. CONCLUSION Antipsychotic treatment should depend on the experience of the physician. Beside haloperidol, no other clear recommendations are available.

León BE, Peyton L, Essa H, Wieden T, Marion N, Childers WE, Abou-Gharbia M, Choi DS. A novel monobactam lacking antimicrobial activity, MC-100093, reduces sex-specific ethanol preference and depressive-like behaviors in mice. Neuropharmacology 2023; 232:109515. [PMID: 37001726 PMCID: PMC10144181 DOI: 10.1016/j.neuropharm.2023.109515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 02/24/2023] [Accepted: 03/21/2023] [Indexed: 03/30/2023]
Abstract
Several β-lactam derivatives upregulate astrocytic glutamate transporter type 1expression and are known to improve measures in models of mood and alcohol use disorders (AUD) through normalizing glutamatergic states. However, long-term, and high doses of β-lactams may cause adverse side effects for treating mood disorders and AUD. Studies suggest that MC-100093, a novel β-lactam lacking antimicrobial activity, rescues GLT1 expression. Thus, we sought to investigate whether MC-100093 improves affective behaviors and reduces voluntary ethanol drinking. We intraperitoneally administered MC-100093 (50 mg/kg) or vehicle once per day to C57BL/6J male and female mice (8-10 weeks old) over 6 days. We employed the open field test and the elevated plus maze to examine the effect of MC-100093 on anxiety-like behaviors. We assayed MC-100093's effects on depressive-like behaviors using the tail suspension and forced swim tests. Next, utilizing a separate cohort of male and female C57BL6 mice, we assessed the effects MC100093 treatment on voluntary ethanol drinking utilizing the 2-bottle choice continuous access drinking paradigm. After screening and selecting high-drinking mice, we systematically administered MC-100093 (50 mg/kg) or vehicle to the high-drinking mice over 6 days. Overall, we found that MC-100093 treatment resulted in sex-specific pharmacological effects with female mice displaying reduced innate depressive-like behaviors during the tail suspension and force swim testing juxtaposed with male treated mice who displayed no changes in tail suspension and a paradoxical increased depressive-like behavior during the forced swim testing. Additionally, we found that MC100093 treatment reduced female preference for 10% EtOH during the 2-bottle choice continuous access drinking with no effects of MC100093 treatment detected in male mice. Overall, this data suggests sex-specific regulation of innate depressive-like behavior and voluntary EtOH drinking by MC100093 treatment. Western blot analysis of the medial prefrontal cortex and hippocampus revealed no changes in male or female GLT1 protein abundance relative to GAPDH.

ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:211-218.

Abstract
BACKGROUND Alcohol withdrawal syndrome (AWS) results from the sudden cessation of chronic alcohol use and is associated with high morbidity and mortality. Alcohol withdrawal-induced central nervous system (CNS) hyperexcitability results from complex, compensatory changes in synaptic efficacy and intrinsic excitability. These changes in excitability counteract the depressing effects of chronic ethanol on neural transmission and underlie symptoms of AWS, which range from mild anxiety to seizures and death. The development of targeted pharmacotherapies for treating AWS has been slow, due in part to the lack of available animal models that capture the key features of human AWS. Using a unique optogenetic method of probing network excitability, we examined electrophysiologic correlates of hyperexcitability sensitive to early changes in CNS excitability. This method is sensitive to pharmacologic treatments that reduce excitability and may represent a platform for AWS drug development. METHODS We applied a newly developed method, the optogenetic population discharge threshold (oPDT), which uses light intensity response curves to measure network excitability in chronically implanted mice. Excitability was tracked using the oPDT before, during, and after the chronic intermittent exposure (CIE) model of alcohol withdrawal (WD). RESULTS Alcohol withdrawal produced a dose-dependent leftward shift in the oPDT curve (denoting increased excitability), which was detectable in as few as three exposure cycles. This shift in excitability mirrored an increase in the number of spontaneous interictal spikes during withdrawal. In addition, Withdrawal lowered seizure thresholds and increased seizure severity in optogenetically kindled mice. CONCLUSION We demonstrate that the oPDT provides a sensitive measure of alcohol withdrawal-induced hyperexcitability. The ability to actively probe the progression of excitability without eliciting potentially confounding seizures promises to be a useful tool in the preclinical development of next-generation pharmacotherapies for AWS.

Front Psychiatry 2023; 14:1141836. [PMID: 37181899 PMCID: PMC10172666 DOI: 10.3389/fpsyt.2023.1141836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 03/22/2023] [Indexed: 05/16/2023] Open
Abstract
Introduction Alcohol use disorder (AUD) is the most prevalent substance use disorder (SUD) globally. In 2019, AUD affected 14.5 million Americans and contributed to 95,000 deaths, with an annual cost exceeding 250 billion dollars. Current treatment options for AUD have moderate therapeutic effects and high relapse rates. Recent investigations have demonstrated the potential efficacy of intravenous ketamine infusions to increase alcohol abstinence and may be a safe adjunct to the existing alcohol withdrawal syndrome (AWS) management strategies. Methods We followed Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines to conduct a scoping review of two databases (PubMed and Google Scholar) for peer-reviewed manuscripts describing the use of ketamine in AUD and AWS. Studies that evaluated the use of ketamine in AUD and AWS in humans were included. We excluded studies that examined laboratory animals, described alternative uses of ketamine, or discussed other treatments of AUD and AWS. Results We identified 204 research studies in our database search. Of these, 10 articles demonstrated the use of ketamine in AUD or AWS in humans. Seven studies investigated the use of ketamine in AUD and three studies described its use in AWS. Ketamine used in AUD was beneficial in reducing cravings, alcohol consumption and longer abstinence rates when compared to treatment as usual. In AWS, ketamine was used as an adjunct to standard benzodiazepine therapy during severe refractory AWS and at signs of delirium tremens. Adjunctive use of ketamine demonstrated earlier resolution of delirium tremens and AWS, reduced ICU stay, and lowered likelihood of intubation. Oversedation, headache, hypertension, and euphoria were the documented adverse effects after ketamine administration for AUD and AWS. Conclusion The use of sub-dissociative doses of ketamine for the treatment of AUD and AWS is promising but more definitive evidence of its efficacy and safety is required before recommending it for broader clinical use.

Abstract
Alcohol is a generic pharmacological agent with only a few recognized primary targets. Nmethyl- D-aspartate, gamma-aminobutyric acid, glycine, 5-hydroxytryptamine 3 (serotonin), nicotinic acetylcholine receptors, and L-type Ca2+ channels and G-protein-activated inwardly rectifying K channels are all involved. Following the first hit of alcohol on specific brain targets, the second wave of indirect effects on various neurotransmitter/neuropeptide systems begins, leading to the typical acute behavioral effects of alcohol, which range from disinhibition to sedation and even hypnosis as alcohol concentrations rise. Recent research has revealed that gene regulation is significantly more complex than previously thought and does not fully explain changes in protein levels. As a result, studying the proteome directly, which differs from the genome/transcriptome in terms of complexity and dynamicity, has provided unique insights into extraordinary advances in proteomic techniques that have changed the way we can analyze the composition, regulation, and function of protein complexes and pathways underlying altered neurobiological conditions. Neuroproteomics has the potential to revolutionize alcohol research by allowing researchers to gain a better knowledge of how alcohol impacts protein structure, function, connections, and networks on a global scale. The amount of information collected from these breakthroughs can aid in identifying valuable biomarkers for early detection and improved prognosis of an alcohol use disorder and future pharmaceutical targets for the treatment of alcoholism.

Prenatal smoking and drinking are associated with altered newborn autonomic functions. Pediatr Res 2023; 93:242-252.

Abstract
BACKGROUND Prenatal smoking and drinking are associated with sudden infant death syndrome and neurodevelopmental disorders. Infants with these outcomes also have altered autonomic nervous system (ANS) regulation. We examined the effects of prenatal smoking and drinking on newborn ANS function. METHODS Pregnant women were enrolled in Northern Plains, USA (NP) and Cape Town (CT), South Africa. Daily drinking and weekly smoking data were collected prenatally. Physiological measures were obtained during sleep 12-96 h post-delivery. RESULTS In all, 2913 infants from NP and 4072 from CT were included. In active sleep, newborns of mothers who smoked throughout pregnancy, compared to non-smokers, had higher breathing rates (2.2 breaths/min; 95% CI: 0.95, 3.49). Quit-early smoking was associated with reductions in beat-to-beat heart rate variability (HRV) in active (-0.08 s) and quiet sleep (-0.11 s) in CT. In girls, moderate-high continuous smoking was associated with increased systolic (3.0 mmHg, CI: 0.70, 5.24) and diastolic blood pressure (2.9 mmHg, CI: 0.72, 5.02). In quiet sleep, low-continuous drinking was associated with slower heart rate (-4.5 beat/min). In boys, low-continuous drinking was associated with a reduced ratio of low-to-high frequency HRV (-0.11, CI: -0.21, -0.02). CONCLUSIONS These findings highlight potential ANS pathways through which prenatal drinking and smoking may contribute to neurodevelopment outcomes. IMPACT In this prospective cohort study of 6985 mother-infant dyads prenatal drinking and smoking were associated with multiple ANS parameters. Smoking was associated with increased neonatal breathing rates among all infants, and heart rate variability (HRV) and blood pressure (BP) among girls. Drinking was associated with reductions in HR and BP among all newborns, and reductions in the ratio of low to-high frequency HRV among boys. These findings suggest that prenatal smoking and drinking alter newborn ANS which may presage future neurodevelopmental disorders.

Abstract
The inferior colliculus (IC) is critical in initiating acoustically evoked alcohol withdrawal-induced seizures (AWSs). Recently, we reported that systemic inhibition of Ca2+ entry via the reverse mode activity of the Na+/Ca2+ exchanger (NCXrev) suppressed AWSs, suggesting remodeling of NCX expression and function, at least in the IC, the site of AWS initiation. Here, we probe putative changes in protein expression in the IC of NCX isoforms, including NCX type 1 (NCX1), 2 (NCX2), and 3 (NCX3). We also evaluated the efficacy of targeted inhibition of NCX1rev and NCX3rev activity in the IC on the occurrence and severity of AWSs using SN-6 and KB-R943, respectively. We used our well-characterized alcohol intoxication/withdrawal model associated with enhanced AWS susceptibility. IC tissues from the alcohol-treated group were collected 3 h (before the onset of AWS susceptibility), 24 h (when AWS susceptibility is maximal), and 48 h (when AWS susceptibility is resolved) following alcohol withdrawal; in comparison, IC tissues from the control-treated group were collected at 24 h after the last gavage. Analysis shows that NCX1 protein levels were markedly higher 3 and 24 h following alcohol withdrawal. However, NCX3 protein levels were only higher 3 h following alcohol withdrawal. The analysis also reveals that bilateral microinjections of SN-6 (but not KB-R7943) within the IC markedly suppressed the occurrence and severity of AWSs. Together, these findings indicate that NCX1 is a novel molecular target that may play an essential role in the pathogenesis and pathophysiology of AWSs.

Abstract
Introduction Delirium tremens (DT) occurs after stopping prolonged, high alcohol intake and may be life-threatening if untreated. We need to know about clinical correlates of DT in order to provide the best clinical care. Methods At admission to inpatient treatment a cohort of 114 alcohol use disorder (AUD) patients were interviewed and examined concerning psychiatric diagnosis and symptoms, trauma experiences and alcohol related measures and if they had experienced DT. Results Twenty-four percent of the patients reported a life-time experience of DT. These patients were predominantly males and had lower educational level. More of the patients in the DT than the non-DT group reported at least one suicide attempt, were diagnosed with PTSD, and dropped out of treatment. Also, having parents with alcohol problems was more common among these patients, and they reported a longer duration of problematic drinking and a higher number of drinks needed to feel an effect of drinking. In the multivariable adjusted analysis only a diagnosis of PTSD (OR=5.71; 95% confidence interval (CI): 1.34–24.31) and duration of problematic drinking with a 6% increase in risk for every year (OR=1.06; 95% CI: 1.01–1.11) remained significant risk factors for having DT experience. Discussion and conclusion Having experienced DT was more prevalent in the current investigation than in earlier studies. Patients that had experienced DT seemed to have more serious AUD, especially signified by a longer duration of drinking. These patients seemed to have many clinical disadvantages including more drop-out and higher suicide rate. PTSD could be a risk factor for DT but may also follow the DT experience.

Abstract
Alcohol withdrawal syndrome (AWS) represents an adverse consequence of chronic alcohol use that may lead to serious complications. Therefore, AWS requires timely attention based on its early recognition, where easy-to-apply diagnostic tools are desirable. Our aim was to characterize the performance of a short-scale AST (Anxiety, Sweats, Tremors) in patients from public general hospitals. We conducted a cross-sectional study of patients attended at the Emergency Department diagnosed with AWS. Three scales were applied: CIWA-Ar (Clinical Institute Retirement Assessment Scale-Revised), GMAWS (Glasgow Modified Alcohol Withdrawal Syndrome) and AST. Cronbach’s alpha and Cohen’s kappa tests were used for reliability and concordance. Factorial analysis and diagnostic performance including ROC curve were carried out. Sixty-eight males with a mean age of 41.2 years old, with high school education and robust alcohol consumption, were included. Mean scores for CIWA-Ar, GMWAS and AST were 17.4 ± 11.2, 3.9 ± 2.3 and 3.8 ± 2.6, respectively, without significant differences. The AST scale showed an acceptable reliability and concordance (0.852 and 0.439; p < 0.0001) compared with CIWA-Ar and GMAWS. AST component analysis evidenced tremor (77.5% variance), sweat (12.1% variance) and anxiety (10.4% variance). Diagnostic performance of the AST scale was similar to the GMAWS scale, evidencing a sensitivity of 84%, specificity of 83.3% and Area Under the Curve (AUC) of 0.837 to discriminate severe AWS, according to CIWA-Ar. The performance of the AST scale to evaluate AWS is comparable with the commonly used CIWA-Ar and GMAWS scales. AST further represents an easy-to-apply instrument.

Acta Psychiatr Scand 2022; 147:430-459. [PMID: 35596552 DOI: 10.1111/acps.13457] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 05/13/2022] [Accepted: 05/17/2022] [Indexed: 01/06/2023]
Abstract
OBJECTIVE Little is known about the economic value of clinical interventions for delirium. This review aims to synthesise and appraise available economic evidence, including resource use, costs, and cost-effectiveness of interventions for reducing, preventing, and treating delirium. METHODS Systematic review of published and grey literature on full and partial economic evaluations. Study quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). RESULTS Fourteen economic evaluations (43% full, 57% partial) across nine multicomponent and nonpharmacological intervention types met inclusion criteria. The intervention costs ranged between US$386 and $553 per person in inpatient settings. Multicomponent delirium prevention intervention and the Hospital Elder Life Program (HELP) reported statistically significant cost savings or cost offsets somewhere else in the health system. Cost savings related to inpatient, outpatient, and out-of-pocket costs ranged between $194 and $6022 per person. The average CHEERS score was 74% (±SD 10%). CONCLUSION Evidence on a joint distribution of costs and outcomes of delirium interventions was limited, varied and of generally low quality. Directed expansion of health economics towards the evaluation of delirium care is necessary to ensure effective implementation that meets patients' needs and is cost-effective in achieving similar or better outcomes for the same or lower cost.

Abstract
BACKGROUND Pellagra caused by niacin deficiency in alcoholics can be easily misdiagnosed because of similar symptoms to other alcohol-related diseases and the lack of the classical triad of signs. AIM This study aimed to define the clinical presentation of alcoholic pellagra for early diagnosis and timely treatment. METHODS The clinical data of 16 alcohol-dependent patients who had pellagra and treated in our hospital from January 2002 to December 2019 were retrospectively analyzed. The local medical ethics committee approval (Medical Ethics Committee of Affiliated Hospital of XuZhou Medical University, XYFY2020-KL247-02) for this study have been obtained. RESULTS The main complaints of the 16 patients were skin lesions (six cases), diarrhea (six cases), and mental disorders (four cases). Then, 13 cases had typical skin lesions, and 3 patients had a full spectrum of diarrhea, dementia, and dermatitis (3D). In terms of the main diagnosis, 2 patients had pellagra and Wernicke's encephalopathy, 3 patients had pellagra and alcohol-withdrawal syndrome, and the other patients had pellagra. After sufficient amounts of niacin and multivitamin B were given, clinical symptoms improved rapidly, and no sequelae were observed during follow-up. CONCLUSIONS Pellagra is rarely manifested as a full 3D spectrum, with only one or two characteristics, which lack diagnostic specificity, especially in individuals with alcoholism. Physicians should maintain a high degree of suspicion of niacin deficiency in alcoholics. Alcohol-dependent patients with pellagra may be accompanied by complications of Wernicke's encephalopathy and alcohol-withdrawal syndrome. Prompt identification and timely treatment with a sufficient amount of niacin in combination with other vitamins and a certain amount of Zn can achieve a good prognosis of pellagra.

Abstract
Older people represent the fastest growing group with epilepsy diagnosis. For example, cerebrovascular disease may underlie roughly 30-50% of epilepsy in older adults and seizures are also an underrecognized comorbidity of Alzheimer's disease (AD). As a result, up to 10% of nursing home residents may take antiseizure medicines (ASMs). Despite the greater incidence of epilepsy in older individuals and increased risk of comorbid seizures in people with AD, aged animals with seizures are strikingly underrepresented in epilepsy drug discovery practice. Increased integration of aged animals into preclinical epilepsy drug discovery could better inform the potential tolerability and pharmacokinetic interactions in aged individuals as the global population becomes increasingly older. Quite simply, the ASMs on the market today were brought forth based on efficacy in young adult, neurologically intact rodents; preclinical information concerning the efficacy and safety of promising ASMs is not routinely evaluated in aged animals. Integrating aged animals more often into basic epilepsy research may also uncover novel treatments for hyperexcitability. For example, cannabidiol and fenfluramine demonstrated clear efficacy in syndrome-specific pediatric models that led to a paradigm shift in the perceived value of pediatric models for ASM discovery practice; aged rodents with seizures or rodents with aging-related neuropathology represent an untapped resource that could similarly change epilepsy drug discovery. This review, therefore, summarizes how aged rodent models have thus far been used for epilepsy research, what studies have been conducted to assess ASM efficacy in aged rodent seizure and epilepsy models, and lastly to identify remaining gaps to engage aging-related neurological disease models for ASM discovery, which may simultaneously reveal novel mechanisms associated with epilepsy.

Abstract
Up to half of individuals with a history of long-term, heavy alcohol consumption will experience the alcohol withdrawal syndrome (AWS) when consumption is significantly decreased or stopped. In its most severe form, AWS can be life-threatening. Medically assisted withdrawal (MAW) often forms the first part of a treatment pathway. This clinical review discusses key elements of the clinical management of MAW, necessary adjustments for pregnancy and older adults, likely outcome of an episode of MAW, factors that might prevent completion of the MAW process and ways of overcoming barriers to ongoing treatment of alcohol use disorder. The review also discusses the use of benzodiazepines in MAW. Although there is clear evidence for their use, benzodiazepines have been associated with abuse liability, blunting of cognition, interactions with depressant drugs, craving, delirium, dementia and disrupted sleep patterns. Because glutamatergic activation and glutamate receptor upregulation contribute to alcohol withdrawal, anti-glutamatergic strategies for MAW and other potential treatment innovations are also considered.

Abstract
Carotid atherosclerosis is a common arterial wall lesion that causes narrowing and occlusion of the arteries and is the basis of cardiovascular events. Dietary habits, lifestyle, and lipid metabolism should be considered integrally in the context of carotid atherosclerosis (CAS). However, this area has been investigated less often in China. To understand the prevalence of CAS in China and the impact of dietary diversity and habits, lifestyle, and lipid metabolism on CAS as well as its predictive factors, a cross-sectional study was performed in two northern and southern Chinese tertiary hospitals from 2017 to 2019. Included participants underwent carotid artery color Doppler ultrasonography, blood lipid examination and dietary evaluation. In total, 11,601 CAS patients and 27,041 individuals without carotid artery lesions were included. The prevalence of CAS was 30.0% in this group. High BMI (OR: 1.685, 95% CI [1.315-2.160]), current (1.148 [1.077-1.224]) or ex-smoking (1.349 [1.190-1.529]), abstinence from alcohol ((1.223 [1.026-1.459]), social engagement (1.122 [1.050-1.198]), hypertension (1.828 [1.718-1.945]), and total cholesterol (1.438 [1.298-1.594]) were risk factors for CAS, while higher dietary diversity according to DDS-2 (0.891 [0.805-0.989]), HDL-C (0.558 [0.487-0.639]), sugar-sweetened beverages (0.734 [0.696-0.774]), and no midnight snack consumption (0.846 [0.792-0.903]) were protective factors. This current study demonstrated that higher dietary diversity was a protective factor against CAS in a healthy population. In addition, current recommendations of healthy lifestyle and dietary habits for preventing CAS should be strengthened. In addition, dietary diversity should concentrate on food attributes and dietary balance, rather than increased quantities.

Abstract
As the number of older adults worldwide continues to grow, we observe a proportional growth of substance use. Despite the myriad of complications alcohol use disorder (AUD) has on the body with regards to organ systems and mental health, the topic has been underresearched in the older adult population. Thus, it is important to create awareness about the growing problem of AUD among older adults. In this way, we can mitigate the long-term complications and side effects observed with alcohol abuse in this vulnerable population.

Abstract
BACKGROUNDS Assessment scales are commonly used to diagnose and treat alcohol withdrawal syndrome (AWS) in acute hospitals, although they have only been validated for use in detoxification facilities. There is a significant overlap between the symptoms and signs of AWS and other clinical presentations, including systemic inflammatory response syndrome (SIRS) and the physiological response to surgery. This may lead to both over-diagnosis and inappropriate treatment of AWS. This study sought to determine the false-positive rate for the commonly used Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) among post-operative patients. METHODS This was a prospective study of patients undergoing major abdominal surgery at University Hospital Geelong. Patients were recruited who were NOT at risk of alcohol dependency (using the World Health Organisation Alcohol Use Disorders Identification Test). Patients were assessed for AWS using the CIWA-Ar day one post-operatively with a false positive measured as a CIWA-Ar > 7. RESULTS A total of 67 patients were included in the study. There were 31 (46%) men and 36 women. Their median age was 52 years (range 27-85). Thirty-six (52%) of patients underwent elective procedures, and 32 were emergencies. Twelve of the 67 patients (18%) had CIWA-Ar scores >seven. CONCLUSION In the early post-operative period, the CIWA-Ar tool over-diagnoses AWS in 18% of patients. These false-positives could lead to delayed treatment of serious underlying conditions. We call for caution in the use of alcohol withdrawal scales in the acute hospital setting.

Abstract
Objective Pheochromocytoma (PCC) crisis caused by acute catecholamine release from an adrenal PCC or extra-adrenal paraganglioma can be difficult to diagnose and may require an unconventional management strategy to achieve good outcomes. We describe a case of PCC crisis presenting with acute respiratory distress syndrome (ARDS) that resolved with stabilization on veno-venous (VV) extracorporeal membrane oxygenation (ECMO) during adrenalectomy. Case Description A 30-year-old man with a history of severe alcohol use disorder and a prior hospital admission for alcohol withdrawal syndrome presented with sudden-onset hemoptysis, altered mental status, and severe dyspnea that rapidly deteriorated to ARDS requiring ECMO support. He demonstrated hemodynamic collapse after cannulation for VV-ECMO and stabilized after conversion to veno-arterial-ECMO, but ARDS persisted and he developed acute renal failure. Computed tomography without contrast done as part of work-up for a presumed infection revealed a 6.9 × 6.4 cm right adrenal mass suspicious for pheochromocytoma. Plasma and random urine metanephrine levels were markedly elevated. ARDS persisted despite α- and β-adrenoreceptor blockade, and he underwent laparoscopic right adrenalectomy with VV-ECMO support. Pathology confirmed PCC with intermediate risk for malignancy. Postoperatively, he was weaned off respiratory and renal support within 10 days, showed rapid clinical improvement, and was discharged 1 month later. Conclusion This case highlights diagnostic and management challenges associated with patients with PCC crisis presenting with ARDS. A multidisciplinary team approach is critical to identifying appropriate treatment strategies.

Abstract
OBJECTIVE To search for objective diagnostic criteria for the development of delirium tremens (DT) based on physiological and metabolic parameters. MATERIAL AND METHODS The total number of patients was 506, including 393 patients with DT and 113 patients with uncomplicated alcohol withdrawal syndrome (UAWS). Twenty clinical and metabolic indicators were analyzed statistically using comparison of means, logistic regression and ROC-analysis. RESULTS AND CONCLUSION Hyponatremia, thrombocytopenia and tachycardia are most prognostically significant indicators, changes in which are observed in the development of DT. These indicators can serve as the basis for objective diagnosis of alcohol withdrawal syndrome complicated by delirium.

Abstract
The association of movement disorders with structural or functional hepatic disease occurs in three principal scenarios: (1) combined involvement of both organ systems from a single disease entity, (2) nervous system dysfunction resulting from exposure to toxic compounds in the setting of defective hepatic clearance, or (3) hepatic and/or neurological injury secondary to exposure to exogenous drugs or toxins. An important early step in the workup of any patient with combined movement disorders and liver disease is the exclusion of Wilson's disease. Diagnostic delay remains common for this treatable disorder, and this has major implications for patient outcomes. Thereafter, a structured approach integrating variables such as age of onset, tempo of progression, nature and severity of liver involvement, movement disorder phenomenology, exposure to drugs/toxins and laboratory/neuroimaging findings is key to ensuring timely diagnosis and disease‐specific therapy. Herein, we provide an overview of disorders which may manifest with a combination of movement disorders and liver disease, structured under the three headings as detailed above. In each section, the most common disorders are discussed, along with important clinical pearls, suggested diagnostic workup, differential diagnoses and where appropriate, treatment considerations.

Abstract
Previous publications have discussed the occurrence of intracerebral hemorrhages, hallucinations and psychosis in COVID-19 patients. In this article, we have reviewed the literature on the subject while depicting the case of a 63-year-old female patient who suffered from an intracerebral hemorrhage in the right basal ganglia and thalamus two weeks after a COVID-19 diagnosis and who developed a visual hallucinosis shortly after. We concluded that, while there may be a correlation between COVID-19 and hallucinations according to current literature, more research is yet needed to clarify. In our case, we rather interpreted the hallucinations in the context of a peduncular hallucinosis related to the intracerebral hemorrhage. We compared our patient’s lesion localization to other 15 reported cases of peduncular hallucinations following intracerebral hemorrhages reported on Pubmed. In summary, the lesions were localized in the pons in 52.9% of the cases, 17.7% were in the thalamus and/or the basal ganglia, 17.7% in the mesencephalon and respectively 5.8% in the temporal and occipital lobe. The distribution pattern we found is consistent with the previously proposed mechanism behind peduncular hallucinations.
