Alcohol Alcohol 2021; 57:155-164. [PMID: 34396386 DOI: 10.1093/alcalc/agab057] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 07/25/2021] [Accepted: 07/25/2021] [Indexed: 11/12/2022] Open
Abstract
AIM To examine the efficacy and safety of antiepileptic drugs (AED) for the inpatient treatment of patients with moderate to severe alcohol withdrawal syndrome (AWS). METHODS We searched in databases and gray literature to include randomized controlled clinical trials in adults that compare the use of AED versus placebo or any other medication. Studies that did not specify severity or were performed on an outpatient basis were excluded. The outcomes were improvement of symptoms, delirium tremens, seizures and adverse events. Two researchers independently selected the references, extracted the data and assessed the risk of bias. A qualitative synthesis was made and, when the heterogeneity was mild or moderate, a meta-analysis was performed. The quality of the evidence obtained was evaluated with the Grading of Recommendations Assessment, Development and Evaluation tool. RESULTS In total, 26 studies with 1709 patients were included. No benefit is described in withdrawal syndrome severity measured by scales or in the development of delirium tremens. The only possible meta-analysis showed that there are no differences in the incidence of seizures (risk ratio [RR] = 1.0; confidence interval (CI) 95% 0.76-1.33), even when compared with placebo (RR = 0.95; CI95% 0.57-1.57). There were also no differences in adverse events, although a higher proportion of some mild cases were described with the use of carbamazepine and valproic acid. CONCLUSIONS The routine use of AED is not suggested in the treatment of patients with moderate or severe AWS unless indicated for comorbidity (weak recommendation against using moderate quality of evidence).

Abstract
Psychoactive substance use during adolescence is an emerging challenge to the public health system due to the potential negative impact on the emotional, cognitive, social, physical and academic outcomes of adolescents. An increase in autonomy during adolescence, peer influence and willingness to experiment, lead to taking high-risk decisions subsequently prompting towards substance abuse and alcohol use. Substance use is heterogeneous among adolescents, which differs with availability, perceptions of use and specific drug usage. In adolescents' substance abuse, beyond emergency care, brief counselling with psychosocial assessment and follow up are recommended for successful management. The article reviews the common substances used by adolescents, types of presentations, clinical evaluation of patients and their background, laboratory testing, emergency management and follow up for long-term management.

Abstract
Substance use disorder is a significant health concern. Hospitalists manage patient with various forms of substance use disorder on a daily basis. In this review, we have tried to synthesize evidence together to give a brief, yet succinct, review of commonly encounters disorders; alcohol intoxication and withdrawal, opioid intoxication and withdrawal, cocaine intoxication and methamphetamine intoxication. We describe clinical features, diagnosis and management, which would serve as a great resource for hospitalist when managing these complicated patients.

Abstract
BACKGROUND The objective of the study is to investigate the incidence and risk factors of delirium after percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) patients accompanied with renal dysfunction. MATERIALS AND METHODS This was a prospective and cohort study, performed in a medical center from July 2014 to June 2017, which enrolled ACS patients accompanied with renal dysfunction who were treated with PCI. Univariate analysis and binary logistic regression analysis was used to determine the incidence and risk factors of delirium. RESULTS Data were analyzed from 119 patients. The 7-day incidence of delirium after PCI in ACS patients accompanied with renal dysfunction was 15.97% (n = 19/119). The binary logistic regression analysis results indicate that age (odd ratio [OR] 1.463; 95% confidence interval [CI] 1.070-2.001; P = 0.017), preoperative higher serum cortisol (COR) (OR 1.025; 95% CI 1.002-1.048; P = 0.030), and lower serum acetylcholine (Ach) (OR 0.965; 95% CI 0.937-0.993; P = 0.016) were significant differences in delirium and nondelirium groups. CONCLUSIONS Age, preoperative higher serum COR levels, and lower serum Ach levels were independent risk factors for delirium after PCI in ACS patients accompanied with renal dysfunction.

Abstract
Postoperative delirium (POD) is a neurobehavioral syndrome caused by dysfunction of neural activity mainly in elderly people. POD is not uncommon, but under-recognized, and often serious. Multifactorial causes including aging, acetylcholine deficiency, sleep deprivation and intraoperative hypoxia have been proposed attempting to explain the processes leading to the development of POD. To date, however, no specific pathophysiologic mechanism has been identified. Here, we summarize the five most prominent theories (neuronal aging, neuroinflammation, neurotransmitter imbalance, neuroendocrine activation, and network connectivity change) to explain the development of delirium. Understanding of the neuropathogenesis of delirium will help focus future research, and assist in developing prophylactic and treatment strategies.

Abstract
BACKGROUND Child maltreatment studies predominantly have operationalized parental substance use as dichotomous variables for any use, any harmful/risky use, or any substance use disorder (SUD). This limits our understanding about how a range of use behaviors may contribute to child maltreatment. OBJECTIVE Build upon prior studies by incorporating a multi-faceted approach to operationalizing parental substance use. METHODS Cross-sectional, secondary data analyses were conducted using the National Survey of Child and Adolescent Well-being (NSCAW I). The study used weighted negative binomial regression to examine relationships between annual child maltreatment frequency and different ways of operationalizing substance use among 2,100 parents. RESULTS Several, inter-related behaviors (i.e., heavy drinking, illicit drug use, polysubstance use, SUD, and prior SUD < 4 years) appeared to be relevant for understanding differences in child maltreatment frequencies. A gradient effect was detected across five substance use behavior patterns: (1) lowest estimated counts were observed for nonusers, light-to-moderate drinkers, and parents with a prior (but not past year) SUD (ӯ < 7.0), (2) slightly higher estimated count was observed for heavy drinkers and/or illicit drug users (ӯ = 9.3), and (3) highest estimated count was observed for parents with past year SUD (ӯ = 17.6). Conclusions/Importance: SUD is a critical screening criteria for potential child harm. Parents reporting risky substance use behaviors may benefit from prevention or brief intervention services related to both their substance use and parenting behaviors. Administrative systems also could benefit from detailed tracking of substance use behaviors for future program evaluation and development.

Abstract
Background: There are varying dosing strategies for the administration of benzodiazepines in the setting of alcohol withdrawal. In October 2014, a symptom-based alcohol withdrawal protocol (AWP) using the Clinical Institute Withdrawal Assessment of Alcohol, Revised (CIWA-Ar) scale was implemented at one institution. Objective: To evaluate the safety and efficacy of the AWP. Methods: Retrospective chart review was completed, including patients receiving at least one dose of diazepam for alcohol withdrawal pre- and post-protocol. The primary outcome of this study was the average daily and cumulative dose of diazepam during hospital stay. Secondary outcomes included length of stay and occurrence of seizures or delirium tremens. Results: The average daily dose and the average cumulative dose of diazepam were significantly lower in the post-protocol group (5.4 vs 12.1 mg, p < .001; 35.0 vs 77.6 mg, p < .001, respectively). Length of stay was similar between groups (6.5 vs 6.4 days, p = .91), however, duration of benzodiazepine use was decreased in the post-protocol group (2.2 vs 4.7 days, p < .001). Despite using reduced doses of benzodiazepines, there was no increase in adverse events. Conclusions: The implementation of a symptom-based AWP using the CIWA-Ar scale was associated with a reduced average daily and cumulative dose of diazepam without any apparent safety issues.

Abstract
Both alcohol withdrawal syndrome (AWS) and benzodiazepines can cause delirium. Benzodiazepine-associated delirium can complicate AWS and prolong hospitalization. Benzodiazepine delirium can be diagnosed with flumazenil, a GABA-A receptor antagonist. By reversing the effects of benzodiazepines, flumazenil is theorized to exacerbate symptoms of AWS and precludes its use. For patients being treated for alcohol withdrawal, flumazenil can diagnose and treat benzodiazepine delirium without precipitating serious or life-threatening adverse events. Hospital admission records were retrospectively reviewed for patients with the diagnosis of AWS who received both benzodiazepines and flumazenil from December 2006 to June 2012 at a university-affiliated inpatient toxicology center. The day of last alcohol consumption was estimated from available blood alcohol content or subjective history. Corresponding benzodiazepine, flumazenil, and adjunctive sedative pharmacy records were reviewed, as were demographic, clinical course, and outcome data. Eighty-five patients were identified (average age 50.3 years). Alcohol concentrations were detectable for 42 patients with average 261 mg/dL (10-530 mg/dL). Eighty patients were treated with adjunctive agents for alcohol withdrawal including antipsychotics (n = 57), opioids (n = 27), clonidine (n = 35), and phenobarbital (n = 23). Average time of flumazenil administration was 4.7 days (1-11 days) after abstinence, and average dose was 0.5 mg (0.2-1 mg). At the time of flumazenil administration, delirium was described as hypoactive (n = 21), hyperactive (n = 15), mixed (n = 41), or not specified (n = 8). Response was not documented in 11 cases. Sixty-two (72.9 %) patients had significant objective improvement after receiving flumazenil. Fifty-six patients required more than one dose (average 5.6 doses). There were no major adverse events and minor adverse effects included transiently increased anxiety in two patients: 1 patient who received 0.5 mg on abstinence day 2 and another patient who received 0.2 mg flumazenil on abstinence day 11. This is the largest series diagnosing benzodiazepine delirium after AWS in patients receiving flumazenil. During the treatment of AWS, if delirium is present on day 5, a test dose of flumazenil may be considered to establish benzodiazepine delirium. With the limited data set often accompanying patients with AWS, flumazenil diagnosed benzodiazepine delirium during the treatment of AWS and improved impairments in cognition and behavior without serious or life-threatening adverse events in our patients.

The "Prediction of Alcohol Withdrawal Severity Scale" (PAWSS): systematic literature review and pilot study of a new scale for the prediction of complicated alcohol withdrawal syndrome. Alcohol 2014; 48:375-90. [PMID: 24657098 DOI: 10.1016/j.alcohol.2014.01.004] [Citation(s) in RCA: 64] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2013] [Revised: 01/22/2014] [Accepted: 01/23/2014] [Indexed: 01/10/2023]
Abstract
BACKGROUND To date, no screening tools for alcohol withdrawal syndromes (AWS) have been validated in the medically ill. Although several tools quantify the severity of AWS (e.g., Clinical Institute Withdrawal Assessment for Alcohol [CIWA]), none identify subjects at risk of AWS, thus missing the opportunity for timely prophylaxis. Moreover, there are no validated tools for the prediction of complicated (i.e., moderate to severe) AWS in the medically ill. OBJECTIVES Our goals were (1) to conduct a systematic review of the published literature on AWS to identify clinical factors associated with the development of AWS, (2) to use the identified factors to develop a tool for the prediction of alcohol withdrawal among patients at risk, and (3) to conduct a pilot study to assess the validity of the tool. METHODS For the creation of the Prediction of Alcohol Withdrawal Severity Scale (PAWSS), we conducted a systematic literature search using PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines for clinical factors associated with the development of AWS, using PubMed, PsychInfo, MEDLINE, and Cochrane Databases. Eligibility criteria included: (i) manuscripts dealing with human subjects, age 18 years or older, (ii) manuscripts directly addressing descriptions of AWS or its predisposing factors, including case reports, naturalistic case descriptions, and all types of clinical trials (e.g., randomized, single-blind, or open label studies), (iii) manuscripts describing characteristics of alcohol use disorder (AUD), and (iv) manuscripts dealing with animal data (which were considered only if they directly dealt with variables described in humans). Obtained data were used to develop the Prediction of Alcohol Withdrawal Severity Scale, in order to assist in the identification of patients at risk for complicated AWS. A pilot study was conducted to assess the new tool's psychometric qualities on patients admitted to a general inpatient medicine unit over a 2-week period, who agreed to participate in the study. Blind to PAWSS results, a separate group of researchers retrospectively examined the medical records for evidence of AWS. RESULTS The search produced 2802 articles describing factors potentially associated with increased risk for AWS, increased severity of withdrawal symptoms, and potential characteristics differentiating subjects with various forms of AWS. Of these, 446 articles met inclusion criteria and underwent further scrutiny, yielding a total of 233 unique articles describing factors predictive of AWS. A total of 10 items were identified as correlated with complicated AWS (i.e., withdrawal hallucinosis, withdrawal-related seizures, and delirium tremens) and used to construct the PAWSS. During the pilot study, a total of 68 subjects underwent evaluation with PAWSS. In this pilot sample the sensitivity, specificity, and positive and negative predictive values of PAWSS were 100%, using the threshold score of 4. DISCUSSION The results of the literature search identified 10 items which may be correlated with risk for complicated AWS. These items were assembled into a tool to assist in the identification of patients at risk: PAWSS. The results of this pilot study suggest that PAWSS may be useful in identifying risk of complicated AWS in medically ill, hospitalized individuals. PAWSS is the first validated tool for the prediction of severe AWS in the medically ill and its use may aid in the early identification of patients at risk for complicated AWS, allowing for prophylaxis against AWS before severe alcohol withdrawal syndromes develop.

Abstract
Alcohol intoxication refers to a clinically harmful condition induced by recent ingestion of alcohol, when alcohol and its metabolites accumulate in the blood stream faster than it can be metabolized by the liver. The major adverse effects of alcohol that gain clinical attention are the neurologic, gastrointestinal, and cardiovascular problems, which are usually related to blood alcohol concentration; however, the extent of acute alcohol intoxication also depends on several factors. Individuals who seek medical treatment for acute alcohol intoxication likely have additional medical problems related to chronic alcohol consumption or alcohol dependence. For this reason, additional investigations to identify potential problems needing particular attention should be considered, depending on the clinical features of the patient.

Abstract
Delirium is a neurobehavioral syndrome caused by dysregulation of neuronal activity secondary to systemic disturbances. Over time, a number of theories have been proposed in an attempt to explain the processes leading to the development of delirium. Each proposed theory has focused on a specific mechanism or pathologic process (e.g., dopamine excess or acetylcholine deficiency theories), observational and experiential evidence (e.g., sleep deprivation, aging), or empirical data (e.g., specific pharmacologic agents' association with postoperative delirium, intraoperative hypoxia). This article represents a review of published literature and summarizes the top seven proposed theories and their interrelation. This review includes the "neuroinflammatory," "neuronal aging," "oxidative stress," "neurotransmitter deficiency," "neuroendocrine," "diurnal dysregulation," and "network disconnectivity" hypotheses. Most of these theories are complementary, rather than competing, with many areas of intersection and reciprocal influence. The literature suggests that many factors or mechanisms included in these theories lead to a final common outcome associated with an alteration in neurotransmitter synthesis, function, and/or availability that mediates the complex behavioral and cognitive changes observed in delirium. In general, the most commonly described neurotransmitter changes associated with delirium include deficiencies in acetylcholine and/or melatonin availability; excess in dopamine, norepinephrine, and/or glutamate release; and variable alterations (e.g., either a decreased or increased activity, depending on delirium presentation and cause) in serotonin, histamine, and/or γ-aminobutyric acid. In the end, it is unlikely that any one of these theories is fully capable of explaining the etiology or phenomenologic manifestations of delirium but rather that two or more of these, if not all, act together to lead to the biochemical derangement and, ultimately, to the complex cognitive and behavioral changes characteristic of delirium.

Abstract
INTRODUCTION Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. The identification of acute alcohol intoxication is extremely important, as well as the alcohol withdrawal syndrome and its complications, such as delirium tremens and Wernicke's encephalopathy in order to grant a timely treatment for those patients. This article introduces the evidence found so as to face and treat these clinic manifestations. METHODOLOGY Systematic revision of the evidence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence. RESULTS Evidence was found and recommendations were made for the diagnosis and treatment of acute alcohol intoxication, withdrawal syndrome, delirium tremens and Wernicke's encephalopathy.

Maldonado JR, Nguyen LH, Schader EM, Brooks JO. Benzodiazepine loading versus symptom-triggered treatment of alcohol withdrawal: a prospective, randomized clinical trial. Gen Hosp Psychiatry 2012; 34:611-7. [PMID: 22898443 DOI: 10.1016/j.genhosppsych.2012.06.016] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2012] [Revised: 05/31/2012] [Accepted: 06/23/2012] [Indexed: 01/05/2023]
Abstract
OBJECTIVES The objectives were to compare the efficacy of a benzodiazepine loading versus a symptom-triggered protocol in the management of alcohol withdrawal. METHODS We conducted a prospective, randomized, controlled trial including 47 consecutive patients admitted to one of two tertiary care medical centers who developed alcohol withdrawal syndrome. Patients were randomly assigned to either a benzodiazepine loading protocol or a symptom-triggered treatment protocol. The Clinical Institute Withdrawal Assessment for Alcohol-Revised scale (CIWA-Ar) was recorded throughout the length of stay, along with measures of autonomic system functioning. RESULTS The average rate of change of CIWA-Ar scores was -1.5 ± 1.3 for the symptom-triggered group and -2.3 ± 2.5 for the loading group. Average rate of change for systolic blood pressure was -2.7 ± 5.3 for the symptom-triggered group and -2.3 ± 6.4 for the loading group. There was no significant difference between the rates of change for either group on either measure. Similarly, there was no significant difference in total benzodiazepine use between groups. Within 72 h of treatment, 69.6% of patients in the loading group were free of withdrawal symptoms versus 41.7% in the symptom-triggered group, a difference not reaching statistical significance. CONCLUSIONS This study did not reveal clear evidence of a clinical advantage for choosing either treatment method.

Analysis of OPCRIT results indicate the presence of a novel 'social functioning' domain and complex structure of other dimensions in the Wielkopolska (Poland) population. Schizophr Res 2012; 138:223-32. [PMID: 22521495 DOI: 10.1016/j.schres.2012.03.032] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2011] [Revised: 01/26/2012] [Accepted: 03/24/2012] [Indexed: 10/28/2022]
Abstract
OBJECTIVE The main goal of our study was to examine factor structure of schizophrenia and bipolar affective disorder in the Wielkopolska population, using dimension reduction techniques. METHODS Schizophrenia (n=443) and bipolar affective disorder (n=499) patients were assessed using Operational Criteria Checklist (OPCRIT). Principal component analysis and Maximum Likelihood Factor analysis were carried out to obtain factor structure with significance level for the factor loadings exceeding 0.4. Varimax and promax rotations were used to identify the meaningful factors. RESULTS Rotated solution indicated multidimensional structure for depression and excitement as well as positive domains in the schizophrenia sample. Negative and disorganized dimensions existed as single factors, with item composition similar to that already described. Additionally, a new "social functioning" dimension was identified. In bipolar affective disorder sample, the interpretable dimensions included: depression, psychotic, atypical depression, negative, substance use, excitement and "social functioning". Factor structure of the combined sample consisted of depression, excitement, disorganization, delusions, substance use, negative and social functioning factors. CONCLUSIONS Our results indicated multidimensional and hierarchical structures for some of the previously described dimensions. Additional use of items not exactly related to disease symptoms lead to discovery of "substance use" and "social functioning" dimensions.
