Alcohol use disorders in the elderly: a brief overview from epidemiology to treatment options

Effect of chronic alcohol feeding using the Lieber-DeCarli diet on Alzheimer's disease pathology in Tg2576 mice

Background

Chronic alcohol drinking is a modifiable risk factor for Alzheimer's disease (AD), but underlying mechanisms remain poorly understood. Most studies of alcohol feeding to AD mice have utilized young mice and delivered alcohol in drinking water without controlling nutritional intake.

Objective

To study the impact of Lieber-DeCarli (LDC) liquid alcohol diet, which balances nutritional intake, on AD pathology of aged Tg2576 and wild-type (WT) mice, which is unexplored.

Methods

13-month-old male and female Tg2576 or WT mice were fed LDC diet (5% ethanol or control) for six weeks (n = 11-13/group). Exploration (open-field test) and spatial reference memory (Y-maze test) were assessed after six weeks, and brains and livers were studied for Aβ levels, and Aβ synthesis and transport proteins (APP and LRP-1). Neuroinflammation, blood-brain barrier function, and synaptic health were studied using immunoassays.

Results

LDC alcohol feeding significantly reduced survival (p < 0.05) and spatial memory (p < 0.05) in Tg2576 mice, but not in WT mice. Alcohol feeding increased (p < 0.001) insoluble endogenous mouse Aβ1-42 and reduced microgliosis (p < 0.05) in Tg2576 mice brains, but not in WT mice. LDC alcohol feeding to Tg2576 mice caused mild liver injury, and important amyloidosis-relevant hepatic proteins (LRP-1 and APP) were largely unaltered. However, brain Aβ and microgliosis were positively correlated (p < 0.05) with serum alanine aminotransferase, a marker of liver injury, in Tg2576 mice.

Conclusion

Chronic alcohol intake, resulting in mild liver injury, caused modest but significant AD-relevant changes in aged Tg2576 mice, which correlated with liver injury; the latter suggests significant liver-brain crosstalk in an AD model of moderate alcohol intake.

The alcohol use disorder treatment gap and its correlates among middle-aged and older adults

INTRODUCTION

Alcohol use disorders (AUD) are under-treated, particularly among older adults. Using data from national treatment registers can expand knowledge on the AUD treatment rate among older adults and on potential biases in treatment receipt. The aim of this paper was to determine the AUD treatment prevalence rate and to investigate sociodemographic, health-related and substance use-related correlates of AUD treatment receipt among older adults with different degrees of problematic alcohol use.

METHODS

The study sample (n = 13,403; inclusion criteria: age 55-80 years, positive CAGE-C) is a subsample from the representative cross-sectional 2017 Danish National Health Survey. It was enriched with data from Danish National Registers, including the National Alcohol Treatment Database. Weighted 12-month AUD treatment prevalence rates were determined. Logistic regression analysis was applied to identify correlates of treatment receipt. All analyses were conducted among: (i) the study sample; (ii) the 28.9% with a positive original CAGE (n = 3725); and (iii) the 6.1% endorsing the CAGE's E-criterion (n = 692).

RESULTS

The 12-month AUD treatment prevalence was 0.5% in the study sample, 1.6% in the CAGE-, and 3.8% in the E-criterion subsample. Not being married or partnered, loneliness and contacts with health care providers were positively associated with AUD treatment receipt in all three samples.

DISCUSSION AND CONCLUSIONS

Even in the subsample with putative alcohol withdrawal, the AUD treatment rate did not reach 5%. This finding suggests that putative AUD is significantly undertreated in older adults. Contacts with other health care providers may facilitate AUD treatment entry in this age group.

Alcohol consumption in elderly people. What is the real magnitude of the problem?

The harmful effects of alcohol consumption have been well studied in the general population, but in the group of people over 80 years of age there is not much information regarding its relevance. It is estimated than 30%-40% of this population consumes alcohol regularly and around 10% engage in high-risk consumption. Furthermore, potential interactions between this substance and commonly consumed drugs in this age group, like oral antidiabetics, anticoagulants and antibiotics, may pose a risk of serious complications. In this sense, the aim of the present work was to analyze the magnitude of alcohol consumption within people over 80 years of age and the impact it has on their health. A narrative review of the available literature on the topic was carried out, which showed that alcohol consumption in people over 80 years of age is common in our environment and is associated with multiple complications and the development of different pathologies. The correct quantification of alcohol consumption in very elderly people must be integrated into the daily clinical practice of Medicine in general and Internal Medicine in particular.

Prevalence and change in alcohol consumption in older adults over time, assessed with self-report and Phosphatidylethanol 16:0/18:1 -The HUNT Study

BACKGROUND

Changes in alcohol consumption may affect older adults' health. We examined prevalence and changes in the alcohol consumption of older women and men (≥65 years) in Norway over a 24-year period.

METHODS

Data from three population-based health surveys (The Trøndelag Health Study-HUNT2 1995-97, HUNT3 2006-08, HUNT4 2017-19) were used. Alcohol consumption was measured using self-reported measures and an objective measure of alcohol consumption (Phosphatidylethanol 16:0/18:1, PEth). Self-reported lifetime abstinence, former drinking, current drinking, frequent drinking (≥4 times/week), and risk drinking (≥8 units/week) were measured. The PEth concentrations were stratified: <0.03 μmol/l (abstinence/very low level of alcohol consumption); >0.06 μmol/l (indicating >1 unit/day); >0.10 μmol/l (indicating >3 units/day), and >0.30 μmol/l (heavy alcohol consumption).

RESULTS

In HUNT4, the prevalence of self-reported lifetime abstinence, frequent drinking, and risk drinking was 5.2%, 4.4%, and 5.6%, respectively, while prevalence of PEth <0.03 μmol/l was 68.1% and PEth >0.06 μmol/l was 21.2%. Over the course of the three surveys, the prevalence of self-reported lifetime abstinence decreased, while the prevalence of frequent drinking and risk drinking increased. Men were less often abstainers and more often frequent and risky drinkers than women in all three surveys. Gender differences for abstinence and current drinking reduced with time. From HUNT3 to HUNT4, the prevalence of PEth <0.03 μmol/l decreased, while the prevalence of PEth >0.06 μmol/l increased. Men compared to women, had less often PEth <0.03 μmol/l and more often PEth >0.06 and >0.10 μmol/l in HUNT3 and HUNT4. Women and men ≥75 years were just as likely to have PEth >0.30 μmol/l in HUNT4. The gender differences in PEth concentrations were reduced in HUNT4 among those aged 70-74 years or ≥75 years.

CONCLUSION

Alcohol consumption has increased among Norwegian older adults over a 24-year period, but at a slower pace during the last decade.

Chronic Liver Disease in the Older Patient-Evaluation and Management

PURPOSE OF REVIEW

As our population ages, the number of elderly patients with advanced chronic liver disease (ACLD) will increase. In this review we explore risk factors for liver injury, noninvasive assessment of liver disease, complications of cirrhosis, and management of frailty and sarcopenia in the older patient with ACLD.

RECENT FINDINGS

Multiple guidelines regarding ACLD have been updated over the past few years. New cutoffs for FIB-4 and NAFLD (MASLD - Metabolic Dysfunction Associated Steatotic Liver Disease) fibrosis scores for elderly patients are being validated. Older patients with MASLD benefit from caloric restriction, exercise programs, and GLP-1 agonists. Patients with ACLD need to be screened for alcohol use disorder with modified scoring systems, and if positive, benefit from referral to chemical dependency programs. Carvedilol and diuretics may safely be used in the elderly for portal hypertension and ascites, respectively, with careful monitoring. Malnutrition, frailty, sarcopenia, and bone mineral disease are common in older patients with ACLD, and early intervention may improve outcomes. Early identification of ACLD in elderly patients allows us to manage risk factors for liver injury, screen for complications, and implement lifestyle and pharmacological therapy to reduce decompensation and death. Future studies may clarify the role of noninvasive imaging in assessing liver fibrosis in the elderly and optimal interventions for nutrition, frailty, sarcopenia, bone health in addition to reevaluation of antibiotic prophylaxis for liver conditions with rising antibiotic resistance.

USING MACHINE LEARNING METHODS TO ASSESS THE RISK OF ALCOHOL MISUSE IN OLDER ADULTS

The population of older adults, defined in this study as those 50 years of age or older, continues to increase every year. Substance misuse, particularly alcohol misuse, is often neglected in these individuals. To better identify older adults who might not be properly assessed for alcohol misuse, we have derived a risk assessment tool using patients from the United Kingdom Biobank (UKB), which was validated on patients in the Weill Cornell Medicine (WCM) electronic health record (EHR). The model and tooling created stratifies the risk of alcohol misuse in older adults using 10 features that are commonly found in most EHR systems. We found that the area under the receiver operating curve (AUROC) to correctly predict alcohol misuse in older adults for the UKB and WCM models were 0.84 and 0.78, respectively. We further show that of those who self-identified as having ongoing alcohol misuse in the UKB cohort, only 12.5% of these patients had any alcohol-related F.10 ICD-10 code. Extending this to the WCM cohort, we forecast that 7,838 out of 12,360 older adults with no F.10 ICD-10 code (63.4%) may be missed as having alcohol misuse in the EHR. Overall, this study importantly prioritizes the health of older adults by being able to predict alcohol misuse in an understudied population.

Recovery from Alcohol Use Disorder among Older Adults: A Scoping Review

Alcohol Use Disorder (AUD) among older people is under-diagnosed even though the population of older people is rising. Recovery from AUD among older people is a challenging process. A scoping review of the literature on recovery from AUD among older people was conducted to characterize the main topics in recovery. A systematic search was conducted in five databases: Psycinfo, Medline, CINHAL, WoS, and Embase from January 2000 to May 2021 using the PRISMA-ScR. Twenty-five studies met the inclusion criteria. The concept of recovery was defined in 20 studies, where the most frequent term was "abstinence." 16 studies described treatment programs with different types of interventions. Six studies described specific programs for older people; five reported positive outcomes. Future studies should implement a broader definition of recovery that reflects the dimensions of the concept and refers to different age groups, to enable interdisciplinary professionals to develop holistic interventions.

Lifestyle, vulnerability to stress and prevailing health conditions of ambulatory older patients in a care facility

Background

Lifestyle and vulnerability to stress are major determinants of age-related health outcomes.

Objectives

To assess the lifestyle and health states of older adults, and evaluate their personality-related vulnerability to stress, to enable improved and targeted health promotional activities.

Methods

A hospital record review and a purposive cross-sectional study was conducted among 200 respondents who were ≥ 50 years old, and visited the General Hospital Oyo, South-western Nigeria. Descriptive statistics was performed using SPSS version 21. Analysis of vulnerability to stress was performed by the addition of scores from Marshal's personality stress prone test. Lifestyle were measured by frequencies and Chi-Square tests, while presence of chronic diseases was measured by respondents' past prescriptions, from the hospital case notes. P < 0.05 was considered statistically significant.

Results

A total of 200 respondents participated in the study. Majority, 156 (78.0%) were 50-59 years old and self-employed 96 (46.0%). Ninety-three (46.5%) smoked, 65 (32.3%) consumed alcohol, 128 (64.0%) had periodic exercise and 67 (33.3%) experienced insomnia. Majority (60.5%) were vulnerable to stress, and this was significantly associated with age (P=0.001), marital status (P=0.021), body weight (P=0.05), occupation (P=0.002) and income (P=0.002). From the retrospective study, most frequently prescribed drugs were anti-hypertensives 225 (69.7%), vitamins/minerals (49.5%), sedatives 158 (48.9%) and analgesics 158 (48.9%) respectively.

Conclusion

Periodic exercise, alcohol use, and smoking were reported at varying degrees. High prevalence of vulnerability to stress and use of anti-hypertensives were also observed, and vulnerability to stress was associated with selected socio-demographics. These findings reinforce the need for routine education of this category of populace on healthy lifestyle for improved health.

Psychiatric Morbidity Among Older Hospitalized Patients

Background

Globally, life expectancy is increasing, leading to an equal proportion of elderly and young individuals, which carries extensive implications. In Bosnia and Herzegovina (BiH), the average age at death in 2021 was 77 years, positioning BiH in the middle of the global list of average life expectancy. Current studiesinvestigate whether the prevalence of psychiatric disorders increases or decreases with age, but results are inconsistent regarding the role of age.There is no prior research on mental disorders in the elderly population in BiH. The experience of the previous war in BiH and the post-war complex "transitional period" have been associated with specific challenges to the mental health of this population, inspiring our research topic.

Objective

The aim of this study was to investigate the psychiatric morbidity in hospitalized individuals aged≥55 years.

Methods

The sample consisted of all patients over age 55 treated at the Department of Psychiatry in Tuzla between January 2018 and December 2020 (N=637), divided into four age categories. Data were obtained from medical records, and for research purposes, a specific questionnaire was constructed.

Results

The predominant psychiatric morbidity stemmed from the category of affective disorders, most common within the "55-64 years" age group, while organic mental disorders were more prevalent in other age groups.Substance use disorders were present in patients aged "55-64 years", with a sharp decline in their prevalence in older age. Female participants had a significantly higher prevalence of affective, psychotic, neurotic, and stress-related disorders, whereas male participants exhibited an increased prevalence of organic mental and substance use disorders.

Conclusion

In total sample, the most prevalent diagnoses belong to the category of affective disorders. Female were most frequently diagnosed with affective disorders, whereas organic mental disorders and substance use disorders prevail in male.

Substance Use Disorders in the Elderly

The population of elderly in the United States with substance use disorders (SUDs) is growing appreciably. SUDs among the elderly are often associated with poor outcomes and are frequently underdiagnosed. The current diagnostic criteria are less sensitive in identifying SUDs among the elderly. Routine screening with validated screening tools may improve the diagnosis of SUDs among the elderly. There is a dearth of data from controlled studies on SUDs among the elderly and the use of pharmacologic agents for treatment, although data indicate that older adults with SUDs respond well to treatments that are specifically designed for this age group.

Alcohol use disorder is associated with higher risks of Alzheimer's and Parkinson's diseases: A study of US insurance claims data

Introduction

Alcohol use disorder (AUD) is on the ascendancy in the US older adult population. The association between AUD and adverse brain outcomes remains inconclusive.

Method

In a retrospective cohort design using US insurance claim data (2007-2020), 129,182 individuals with AUD were matched with 129,182 controls by age, sex, race, and clinical characteristics. We investigated the association between AUD and adverse brain outcomes using Cox analysis, Kaplan-Meier analysis, and log-rank test.

Results

After adjusting for covariates, AUD was associated with a higher risk of Alzheimer's disease (female adjusted hazard ratio [HR] = 1.78, 95% confidence interval [CI]: 1.68-1.90, p < 0.001; male adjusted HR = 1.80, 95% CI: 1.71-1.91, p < 0.001) and a higher risk of Parkinson's disease (female adjusted HR = 1.49, 95% CI: 1.32-1.68, p < 0.001; male adjusted HR = 1.42, 95% CI: 1.32-1.52, p < 0.001) in the overall sample. In separate analyses of Black, White, and Hispanic individuals, those with AUD had higher risk of Alzheimer's disease (adjusted HRs ≥1.58; Ps ≤ 0.001). A significantly elevated risk for Parkinson's disease was found only in the White subpopulation (female adjusted HR = 1.55, 95% CI: 1.36-1.77, p < 0.001; male adjusted HR = 1.45, 95% CI: 1.33-1.57, p < 0.001).

Conclusions

AUD is associated with Alzheimer's disease. AUD is associated with Parkinson's disease in White people. Cognitive screening and neurological examination among older adults with AUD hold the promise for early detection of Alzheimer's disease and Parkinson's disease.

HIGHLIGHTS

Alcohol use disorder is associated with Alzheimer's disease and dementia.Alcohol use disorder is associated with Parkinson's disease in White people.

Comparison of self-reported alcohol consumption and ethyl glucuronide in hair in a sample of 60+ year -olds treated for DSM-5 alcohol use disorder

There is a lack of evidence for the consistency between self-reported alcohol consumption (SRAC) and concentrations of ethyl glucuronide in hair (hEtG) among elderly patients treated exclusively for alcohol use disorder (AUD). Hence, this study assessed the consistency between these two measures in these patients. A total of 190 patients with AUD were assessed for SRAC using Form 90 and hEtG, 14 or 22 weeks after treatment conclusion. Patients were grouped according to SRAC (g/day) and corresponding hEtG concentrations (pg/mg): 0 and <5 (abstinence), 0.1-14.3 and 5.0-9.9 (low consumption), 14.4-21.4 and 10.0-15.9 (moderate consumption), 21.5-59.9 and 16.0-30 (high consumption) and ≥60 and >30 (excessive consumption). The extent of underreporting and overreporting was examined by crosstabulations, and inter-rater reliability was reported by kappa correlations. Associations and effect modification were examined by conditional logistic regression. Due to multitesting, p-values ≤0.01 were considered significant. Underreporting was found in 96 patients (50.5%) and overreporting in 41 patients (21.6%). The kappa coefficients varied between 0.19 and 0.34. HEtG was more likely to detect low, moderate and high alcohol consumption compared with SRAC (ORs between 5.1 and 12.6, all p-values <0.01), but SRAC and hEtG did not differ significantly with respect to identification of abstinence (OR = 1.9, p = 0.05). Inconsistency between the outcome measures was found in a considerable number of the patients. More studies examining the consistency between SRAC and specific direct biomarkers of alcohol in this population seem warranted.

Recurrent risk of hospitalization among older people with problematic alcohol use: a multiple failure-time analysis with a discontinuous risk model

BACKGROUND AND AIMS

Older people with problematic alcohol use vary in psychosocial functioning, age of onset for problem drinking and use of other drugs. The study measured the differential risks of all-cause, alcohol-, polydrug- and psychiatric-related repeated hospitalizations among older people with problematic alcohol use.

DESIGN

A linked register-based cohort study with discontinuous multiple-failure (time-to-repeated-event) data. Hospitalization and mortality were considered as failure.

SETTING

Sweden, March 2003-November 2017, using data from the Addiction Severity Index (ASI) register linked to National Inpatient Register and the Swedish cause of death register.

PARTICIPANTS

Participants aged 50 years and older (n = 1741; 28.2% women), with one or more alcohol problem days in the 30 days before an ASI assessment.

MEASUREMENTS

Five mutually exclusive latent classes of problematic alcohol use, identified with 11 ASI items, were the independent variables: 'late onset with fewer consequences (LO:FC; reference group)'; 'early onset/prevalent multi-dimensional problems (EO:MD)'; 'late onset with co-occurring anxiety and depression (LO:AD)'; 'early onset with co-occurring psychiatric problems (EO:PP)'; and 'early onset with major alcohol problem (EO:AP)'. Covariates included socio-demographic characteristics, previous hospitalization and Elixhauser comorbidity index. Outcome measurements included recurrent hospitalization and/or mortality due to: (a) all-cause, (b) alcohol-related disorders and diseases (c) polydrug use and (d) other psychiatric disorders.

FINDINGS

During the study period, more than 75% were hospitalized at least once or died. 57.3% were hospitalized with alcohol-related, 8.5% with polydrug use and 18.5% with psychiatric-related diagnoses. Compared with LO:FC, EO:PP had higher risk for all-cause [adjusted hazard ratio (aHR) = 1.27, 95% confidence interval (CI) = 1.02-1.59] and alcohol-related (aHR = 1.34, 95% CI = 1.02-1.75) hospitalizations. Adjusted risks for polydrug-related hospitalization were 2.55, 95% CI = 1.04-6.27 for EO:MD and 2.62, 95% CI = 1.07-6.40 for EO:PP. Adjusted risk for psychiatric-related hospitalization was higher for LO:AD (aHR = 1.78, 95% CI = 1.16-2.73 and EO:PP (aHR = 2.03, 95% CI = 1.22-3.38).

CONCLUSIONS

Older addiction service users in Sweden have varying risks of hospitalization due to alcohol use, polydrug use and psychiatric disorders. Older people with problematic alcohol use who have multiple needs and are assessed in social services may benefit from earlier interventions with an integrated focus on substance use and mental health.

Aging successfully, but still vulnerable: Late life experiences of older adults who have recovered from alcohol use disorder

OBJECTIVE

The population of older adults suffering from alcohol use disorder (AUD) is increasing worldwide. Recovery from AUD among older adults is a challenging process which can lead to amelioration in these individuals' physical, mental, familial and social domains. However, little is known about the life experiences of older adults who have recovered from AUD.

METHOD

A qualitative-naturalistic approach was implemented. Semi-structured in-depth interviews were conducted with 20 older adults, age 60 +, who had recovered from AUD for periods ranging from 1 to 9 years.

RESULTS

Three main categories emerged from the content analysis: a) Regrets, self-forgiveness and a desire to remedy past wrongs; b) successful aging and eagerness to live; c) enduring challenges. These categories reflect the complex and multidimensional experiences of older adults who have recovered from AUD.

CONCLUSION

Older adults who recover from AUD report experiencing successful aging. They are willing to engage in new ventures in late life, live actively and age healthfully. However, despite their positive outlook, older adults recovering from AUD are a vulnerable population, especially when they experience marginalization as post-AUD older adults. This underscores the need to reach out to this population and the host of challenges they face to provide supportive treatments and interventions from interdisciplinary professionals who can guide their recovery from AUD and help them flourish in late life.

Alcohol consumption among older adults with symptoms of cognitive decline consulting specialist health care

OBJECTIVES

To explore alcohol consumption among older Norwegian adults with symptoms of cognitive decline, assess the agreement between the reports of older adults and their next of kin regarding a person's alcohol consumption, and explore clinical and sociodemographic variables associated with agreement.

METHOD

Alcohol consumption was measured among 3608 older adults consulting specialist health care for symptoms of cognitive decline. Agreement between the participant and their next of kin regarding the participant's alcohol consumption was assessed with a weighted kappa (κ). A logistic regression analysis for hierarchical data was used to explore variables associated with agreement.

RESULTS

Both the participants and their next of kin reported that more than 20% of the participants consumed alcohol 1-3 times a week, and that approximately 10% consumed alcohol four or more times a week. The agreement between the participant's and their next of kin's report regarding the participant's alcohol consumption was high (κ = .852), and variables associated with agreement were no cognitive decline, not drinking alcohol during the last year or ever as reported by the participant, and low agitation scores on a psychiatric assessment.

CONCLUSION

This paper found alcohol consumption among older adults with symptoms of cognitive decline that was above the national average in Norway. This is also the first paper to demonstrate that a next of kin can be a reliable source of information regarding older adults' alcohol consumption. Health personnel should consider these findings when performing medical assessments or developing interventions for older adults.

Patterns of Alcohol Consumption and Associated Factors in a Population-Based Sample of 70-Year-Olds: Data from the Gothenburg H70 Birth Cohort Study 2014-16

Older adults of today consume more alcohol, yet knowledge about the factors associated with different consumption levels is limited in this age group. Based on the data from a population-based sample (n = 1156, 539 men and 617 women) in The Gothenburg H70 Birth Cohort Study 2014−16, we examined sociodemographic, social, and health-related factors associated with alcohol consumption levels in 70-year-olds, using logistic regression. Total weekly alcohol intake was calculated based on the self-reported amount of alcohol consumed. Alcohol consumption was categorized as lifetime abstention, former drinking, moderate consumption (≤98 g/week), and at-risk consumption (>98 g/week). At-risk consumption was further categorized into lower at-risk (98−196 g/week), medium at-risk (196−350 g/week), and higher at-risk (≥350 g/week). We found that among the 1156 participants, 3% were lifetime abstainers, 3% were former drinkers, 64% were moderate drinkers, and 30% were at-risk drinkers (20% lower, 8% medium, 2% higher). Among several factors, former drinking was associated with worse general self-rated health (OR 1.65, 95% CI 1.08−2.51) and lower health-related quality of life (measured by physical component score) (OR 0.94, 95% CI 0.91−0.97), higher illness burden (OR 1.16, 95% CI 1.07−1.27), and weaker grip strength (OR 0.96, 95% CI 0.94−0.98). Higher at-risk drinkers more often had liver disease (OR 11.41, 95% CI 3.48−37.37) and minor depression (OR 4.57, 95% CI 1.40−14.95), but less contacts with health care (OR 0.32, 95% CI 0.11−0.92). Our findings demonstrate the importance of classifications beyond abstinence and at-risk consumption, with implications for both the prevention and clinical management of unhealthy consumption patterns in older adults.

Experiences of a therapist-guided internet-delivered intervention for hazardous and harmful drinking. A qualitative study

BACKGROUND

Alcohol is the third leading risk factor for burden of disease in the world, causing significant health damage to the individual as well as costs to the surroundings and society as whole. Internet-delivered psychological interventions may help the individual to address alcohol consumption at an early stage before it develops into more serious problems. There is a need to investigate how participants experience internet-delivered interventions for hazardous and harmful drinking to optimize its usefulness in the target population.

METHODS

The present study was part of an open pre-post pilot trial to evaluate the feasibility and acceptability of a therapist-guided internet-delivered cognitive behavioural intervention for hazardous and harmful alcohol use. The aim was to investigate participants` experiences of the intervention and the ways in which the intervention helped them to address their alcohol consumption. Fifteen participants were selected from the open pre-post trial (n = 32), and semi-structured interviews were conducted immediately after participants had completed the treatment. The interviews were analysed using Thematic Analysis.

RESULTS

The results indicate that most of the participants found the intervention to be useful. Participants reported that the intervention made them more aware of the consequences of excessive drinking and gave them tools to cope with their alcohol consumption. Among the perceived advantages were the flexibility and anonymity of the intervention and therapist support. Participants called for more individualisation of the treatment to meet individual needs.

CONCLUSIONS

A therapist-guided internet-delivered intervention for hazardous and harmful drinking can help individuals to address their alcohol consumption and give them tools to cope with their drinking. Future studies should examine the feasibility of tailoring modules to individual needs.

Sex differences in at-risk drinking and associated factors-a cross-sectional study of 8,616 community-dwelling adults 60 years and older: the Tromsø study, 2015-16

BACKGROUND

Alcohol consumption among older adults is on the rise, which may be an increasing public health concern. The proportion of older adults who drink above defined low-risk drinking limits, associated characteristics and the sex distribution of at-risk drinking vary across countries. The aims of this study were to (i) estimate the prevalence of at-risk drinking among older adults in Norway, (ii) investigate factors associated with at-risk drinking, and (iii) examine sex differences in alcohol consumption in the context of sociodemographic and selected health characteristics.

METHOD

A cross-sectional study based on Tromsø 7 (2015-16), an ongoing population-based cohort survey. Data were retrieved from participants aged 60 and older (60-99 years) who answered questions about alcohol consumption (n = 8,616). Sex-stratified logistic regressions were used to assess the association between three at-risk drinking outcome variables, and sociodemographic and selected health characteristics. The outcome variables were operationalized using the Alcohol Use Disorders Identification Test (AUDIT), and Alcohol Consumption Questions (AUDIT-C), i.e. - cut off for at risk drinking, drinking any 6+ in the past year, and any alcohol problems.

RESULTS

The overall prevalence of at-risk drinking among those aged 60-99 years was equal in women and men; 44% and 46%, respectively. At-risk drinking was strongly associated with a higher level of education, with OR 2.65 (CI 2.28-3.10) in women and OR 1.73 (CI 1.48-2.04) in men.

CONCLUSIONS

Almost half of older adults in Norway exceeded sex- and older adult-specific at-risk drinking thresholds. Our findings suggest some differences in factors associated with at-risk drinking between women and men. Explicitly, at-risk drinking was associated with very good health, living with a spouse or partner, and having adequate social support in women, while it was associated with the use of sleeping pills in men. Our findings suggest that women exceed at-risk drinking thresholds with better health, while men exceed at-risk drinking thresholds regardless of good or poor health.

Late-Onset Alcohol Abuse as a Presenting Symptom of Neurodegenerative Diseases

BACKGROUND

The association between lifetime alcohol abuse and a higher risk to develop dementia is well known. However, it is unknown whether older adults who begin abusing alcohol late in life have an underlying neurodegenerative disease.

OBJECTIVE

Identify the frequency of lifelong alcohol abuse (L-AA), late-onset alcohol abuse (LO-AA), and alcohol abuse as a first symptom of dementia (AA-FS) in patients with neurodegenerative diseases.

METHODS

Cross-sectional retrospective study of patients evaluated at an academic referral center with a clinical diagnosis of behavioral variant frontotemporal dementia (bvFTD), Alzheimer-type dementia (AD), and semantic variant primary progressive aphasia (svPPA) (n = 1,518). The presence of alcohol abuse was screened with the National Alzheimer's Coordinating Center questionnaire. L-AA was defined as onset < 40 years, LO-AA as onset ≥40 years, and AA-FS was defined when the abuse started within the first three years from symptom onset.

RESULTS

The frequency of LO-AA was 2.2% (n = 33/1,518). LO-AA was significantly more frequent in patients with bvFTD than AD (7.5%, n = 13/173 versus 1.3%, n = 16/1,254, CI:1.0;11.4%), but not svPPA (4.4%, n = 4/91, CI: -4.4;10.7%). Similarly, AA-FS was more frequent in bvFTD patients than AD (5.7%, n = 10/173 versus 0.7%, n = 9/1,254, CI:0.5%;9.5%), but not svPPA (2.2%, n = 2/91, CI:-2.4;9.1%).

CONCLUSION

LO-AA can be a presenting symptom of dementia, especially bvFTD. Alcohol abuse onset later in life should prompt a clinical investigation into the possibility of an underlying neurodegenerative process because delay in diagnosis and treatment may increase patient and caregiver burden. The results need to be interpreted with caution due to the limitations of the study.

Corticotropin Releasing Factor Binding Protein as a Novel Target to Restore Brain Homeostasis: Lessons Learned From Alcohol Use Disorder Research

Stress is well-known to contribute to the development of many psychiatric illnesses including alcohol and substance use disorder (AUD and SUD). The deleterious effects of stress have also been implicated in the acceleration of biological age, and age-related neurodegenerative disease. The physio-pathology of stress is regulated by the corticotropin-releasing factor (CRF) system, the upstream component of the hypothalamic-pituitary-adrenal (HPA) axis. Extensive literature has shown that dysregulation of the CRF neuroendocrine system contributes to escalation of alcohol consumption and, similarly, chronic alcohol consumption contributes to disruption of the stress system. The CRF system also represents the central switchboard for regulating homeostasis, and more recent studies have found that stress and aberrations in the CRF pathway are implicated in accelerated aging and age-related neurodegenerative disease. Corticotropin releasing factor binding protein (CRFBP) is a secreted glycoprotein distributed in peripheral tissues and in specific brain regions. It neutralizes the effects of CRF by sequestering free CRF, but may also possess excitatory function by interacting with CRF receptors. CRFBP's dual role in influencing CRF bioavailability and CRF receptor signaling has been shown to have a major part in the HPA axis response. Therefore, CRFBP may represent a valuable target to treat stress-related illness, including: development of novel medications to treat AUD and restore homeostasis in the aging brain. This narrative review focuses on molecular mechanisms related to the role of CRFBP in the progression of addictive and psychiatric disorders, biological aging, and age-related neurodegenerative disease. We provide an overview of recent studies investigating modulation of this pathway as a potential therapeutic target for AUD and age-related neurodegenerative disease.

Distinct health-related risk profiles among middle-aged and older adults with risky alcohol use from the Danish general population

BACKGROUND

Knowledge is lacking on distinct health-related risk profiles among the substantial group of middle-aged and older adults with risky alcohol use (AU). Such profiles could inform the planning of interventions and prevention.

AIMS

To 1) identify distinct health-related profiles based on different types of health-related functioning limitations and distress and 2) assess associations between these profiles and age, sex, and health-relevant behaviors (e.g., smoking).

METHODS

Cross-sectional nation-wide Danish health survey with n = 6630 adults aged 55-64 and n = 7605 aged 65-74 with at least risky AU (>84 g ethanol/week in women, >168 in men). Health-related risk profiles were identified with Latent Class Analysis (LCA). Multinomial regression was applied for the association between risk profiles and auxiliary variables.

RESULTS

A six-class LCA solution was found among 55-64 year-olds (classes: 'Normative' [61%], 'Distress' [6%], 'Mental health limitations [5%]', 'Pain-related distress [10%]', 'Broad limitations and pain distress [7%]', 'High overall burden' [11%]) and a five-class solution among 65-74 year-olds. Most classes were comparable across age groups. The 'Distress'-class characterized by pain-distress, tiredness-distress, and sleep-related distress (6%) only showed in the younger group. In both age groups, auxiliary covariates (high-risk AU, possible alcohol use disorder, weekly smoking) were positively associated with problematic profile membership (vs. normative class membership).

CONCLUSION

Middle-aged and older adults with risky AU have distinct health-related profiles relevant for the form and content of prevention and interventions. Despite their distinct features, almost all problematic health profiles warrant careful attention regarding high-risk AU and probable alcohol use disorder.

The Prognostic Role of DSM-5 Alcohol Use Disorder Severity and Age of Onset in Treatment Outcome Among Adults Aged 60

AIMS

To investigate among older adults with DSM-5 alcohol use disorder (AUD) the relevance of (1) baseline DSM-5 AUD severity, (2) age of DSM-5 AUD onset, and (3) the interactions of DSM-5 AUD severity*treatment condition and age of DSM-5 AUD onset*treatment condition for the prediction of AUD treatment outcomes.

METHODS

The international multicenter RCT "ELDERLY-Study" compared outpatient motivational enhancement therapy (4 sessions) with outpatient motivational enhancement therapy followed by community reinforcement approach for seniors (8 sessions) in adults aged 60+ with DSM-5 AUD. Baseline and 1-, 3-, and 6-month follow-up data from the German and Danish ELDERLY-sites (n = 544) were used (6-month participation rate: 75.9%). DSM-5 AUD diagnoses were obtained using the Mini International Neuropsychiatric Interview and alcohol use using Form 90. Associations between DSM-5 AUD severity and age of onset and AUD treatment outcomes were investigated using multiple logistic regression and generalized linear models.

RESULTS

The sample was diverse in AUD severity (severe: 54.9%, moderate: 28.2%, mild: 16.9%) and age of onset (median: 50 years; 12-78 years). Overall, with few exceptions, neither AUD severity, nor age of onset, nor their respective interactions with treatment condition significantly predicted drinking outcomes at the different follow-ups (P ≥ 0.05).

CONCLUSIONS

No indication was found for the need to tailor treatment content according to DSM-5 AUD severity and earlier onset in older adults.

Health Professionals' Experiences Regarding Alcohol Consumption and Its Relation to Older Care Recipient's Health and Well-Being

BACKGROUND

Alcohol consumption among older people is expected to increase in the years ahead. Health professionals' experiences of, and reflections on, alcohol consumption and its relation to well-being are thus important to the provision of adequate and high-quality treatment and care.

AIM

To investigate health professionals' experiences and reflections about alcohol consumption among older people and how it is related to their health and well-being.

METHODS

A case study design approach was adopted, incorporating three qualitative studies involving Norwegian health professionals. The health professionals interviewed included workers in nursing homes, home care professionals and general practitioners.

RESULTS

The study revealed a diversity of views and reflections on alcohol consumption, its facilitation, and the impact on the health and well-being of older patients and care recipients. Six themes were revealed by the three studies: (i) the facilitation of alcohol consumption to promote and normalize life in nursing homes, (ii) the restriction of unhealthy alcohol consumption, (iii) attempts to discuss alcohol consumption with care recipients, (iv) the initiation of collaboration with informal caregivers in restricting alcohol consumption, (v) minimalizing the dialogue regarding alcohol consumption to guard patient privacy and (vi) a desire for joint action and a national political strategy.

CONCLUSION

Health professionals working in NHs, in-home and GPs find it difficult to discuss the use and elevated use of alcohol with older people for whom they have care and treatment responsibilities. In general, they are concerned that such conversations infringe on the principles governing an individual's autonomy. However, because they are aware that elevated alcohol intake may have a negative impact on health and well-being, they also express a need for guidelines how they in a better and open minded way can discuss the use and elevated use of alcohol with the patients they care for.

Impact of Alcohol Abuse on Susceptibility to Rare Neurodegenerative Diseases

Despite the prevalence and well-recognized adverse effects of prenatal alcohol exposure and alcohol use disorder in the causation of numerous diseases, their potential roles in the etiology of neurodegenerative diseases remain poorly characterized. This is especially true of the rare neurodegenerative diseases, for which small population sizes make it difficult to conduct broad studies of specific etiological factors. Nonetheless, alcohol has potent and long-lasting effects on neurodegenerative substrates, at both the cellular and systems levels. This review highlights the general effects of alcohol in the brain that contribute to neurodegeneration across diseases, and then focuses on specific diseases in which alcohol exposure is likely to play a major role. These specific diseases include dementias (alcohol-induced, frontotemporal, and Korsakoff syndrome), ataxias (cerebellar and frontal), and Niemann-Pick disease (primarily a Type B variant and Type C). We conclude that there is ample evidence to support a role of alcohol abuse in the etiology of these diseases, but more work is needed to identify the primary mechanisms of alcohol's effects.

Elevated alcohol consumption among geriatric psychiatric in-patients

Introduction:

Although a clear relationship has been established between elevated alcohol consumption and psychiatric problems in old age, there are few descriptions of the prevalence of elevated alcohol consumption in older adults who have been referred to geriatric psychiatric treatment.

Aim:

To describe the prevalence of self-reported elevated alcohol consumption in men and women referred to geriatric psychiatry wards in Norway, and to explore factors associated with elevated alcohol consumption.

Method:

This cross-sectional study includes data from a registry of geriatric psychiatry patients aged ≥ 65 years from December 2016 until December 2018. The outcome measure was reported elevated alcohol consumption assessed with the short version of the Alcohol Use Disorders Identification Test (AUDIT-C). The analyses used demographic data as well as a measure of cognitive function, psychiatric diagnosis and use of psychotropic drugs.

Results:

In total, 367 patients (131, 35.7% men) with a mean (SD) age of 74.7 (7.6) years were included. Of these patients, 27% scored above the pre-set cut-off for elevated alcohol consumption according to AUDIT-C (≥ 3 and 4 for women and men, respectively). The prevalence of elevated alcohol did not differ by gender. In adjusted logistic regression analysis, older age, living with someone and use of antidepressants were associated with reduced odds for reporting elevated alcohol consumption (OR 0.93, 95% CI 0.89–0.96; OR 0.54, 95% CI 0.31–0.97; and 0.54, 95% CI 0.32–0.92, respectively).

Conclusion:

A relatively high proportion of psychiatric patients aged 65 years or older reported elevated alcohol consumption, regardless of diagnosis. Older age, living with someone and use of antidepressants were associated with lower odds for elevated alcohol consumption.

The psychological consequences of (perceived) ionizing radiation exposure: a review on its role in radiation-induced cognitive dysfunction

PURPOSE

Exposure to ionizing radiation following environmental contamination (e.g., the Chernobyl and Fukushima nuclear accidents), radiotherapy and diagnostics, occupational roles and space travel has been identified as a possible risk-factor for cognitive dysfunction. The deleterious effects of high doses (≥1.0 Gy) on cognitive functioning are fairly well-understood, while the consequences of low (≤0.1 Gy) and moderate doses (0.1-1.0 Gy) have been receiving more research interest over the past decade. In addition to any impact of actual exposure on cognitive functioning, the persistent psychological stress arising from perceived exposure, particularly following nuclear accidents, may itself impact cognitive functioning. In this review we offer a novel interdisciplinary stance on the cognitive impact of radiation exposure, considering psychological and epidemiological observations of different exposure scenarios such as atomic bombings, nuclear accidents, occupational and medical exposures while accounting for differences in dose, rate of exposure and exposure type. The purpose is to address the question that perceived radiation exposure - even where the actual absorbed dose is 0.0 Gy above background dose - can result in psychological stress, which could in turn lead to cognitive dysfunction. In addition, we highlight the interplay between the mechanisms of perceived exposure (i.e., stress) and actual exposure (i.e., radiation-induced cellular damage), in the generation of radiation-induced cognitive dysfunction. In all, we offer a comprehensive and objective review addressing the potential for cognitive defects in the context of low- and moderate-dose IR exposures.

CONCLUSIONS

Overall the evidence shows prenatal exposure to low and moderate doses to be detrimental to brain development and subsequent cognitive functioning, however the evidence for adolescent and adult low- and moderate-dose exposure remains uncertain. The persistent psychological stress following accidental exposure to low-doses in adulthood may pose a greater threat to our cognitive functioning. Indeed, the psychological implications for instructed cohorts (e.g., astronauts and radiotherapy patients) is less clear and warrants further investigation. Nonetheless, the psychosocial consequences of low- and moderate-dose exposure must be carefully considered when evaluating radiation effects on cognitive functioning, and to avoid unnecessary harm when planning public health response strategies.

The relationship of cannabis decriminalization in Colorado and cannabis use in individuals with alcohol use disorders

OBJECTIVE

Over the past decade, cannabis use has become increasingly popular in states that include Colorado. During this time, alcohol use disorders (AUDs) and alcohol-related medical conditions have also been consistently recognized as public health problems with increasing prevalence in the state. Despite the widespread use of cannabis in Colorado, the epidemiology of cannabis use among those with AUDs has been poorly described. Therefore, we sought to examine cannabis use among individuals with likely AUDs and individuals with low-risk alcohol use during a time of major Colorado legislative changes before and after legalization of recreational cannabis in 2012.

METHODS

This study was a secondary data analysis conducted with information from 303 participants (80% male) in the Denver, CO metropolitan enrolled between August 2007 and April 2016 for studies related to alcohol and lung health. Of these participants, 188 (62%) were completing inpatient alcohol detoxification with likely AUDs. All participants completed the Alcohol Use Disorder Identification Test (AUDIT) to establish their likelihood of an AUD, and all had information on current cannabis use assessed by questionnaire and urine toxicology testing.

RESULTS

Individuals with likely AUDs more commonly used cannabis compared to control participants (42% vs 27%, p = 0.007). In multiple logistic regression analyses, participant type (likely AUD versus control), tobacco smoking, and age were significantly associated with cannabis smoking; however, the year of participant enrollment was not. Adjusted odds for cannabis use among participants with likely AUDs were 2.97 (1.51-5.82), p = 0.002, while odds for cannabis use among tobacco smokers were 3.67 (1.94-6.93), p < 0.0001. Among control participants, tobacco smoking increased odds of cannabis use seven-fold.

CONCLUSIONS

Our findings highlight the exceptionally high odds of cannabis use among individuals with likely AUDs undergoing alcohol detoxification at a Colorado treatment facility before and after legalization of recreational cannabis. Targeted investigations into the medical and psychiatric consequences of combined alcohol and cannabis use are urgently needed to define its health impact in these vulnerable individuals.

An Evaluation of the Clinical and Economic Burden Among Older Adult Medicare-Covered Beneficiaries With Treatment-Resistant Depression

OBJECTIVE

To compare the clinical and economic burden of treatment-resistant depression (TRD) among older adult patients with major depressive disorder (MDD) to non-TRD MDD and non-MDD patients.

METHODS

Retrospective cohort study using 5% Medicare data (January 1, 2012-December 31, 2015) for MDD patients aged ≥65 years who were defined as TRD if they received ≥2 antidepressant treatments in the current episode. MDD patients not meeting TRD criteria were deemed non-TRD MDD; those without an MDD diagnosis were categorized as non-MDD. All were required to have continuous health plan enrollment for ≥6 months pre- and ≥12 months postindex date (index: first antidepressant claim/random [non-MDD]). Three cohorts were matched, and generalized linear and Cox proportional hazards models were used to compare medication use, healthcare resource utilization, costs, and risks of initial hospitalization and readmission ≤30 days postdischarge from initial hospitalization.

RESULTS

After matching, 178 patients from each cohort were analyzed. During 12 months of follow-up, TRD patients had higher use of different antidepressants and antipsychotics, higher inpatient and emergency room visits, longer inpatient stays, and higher total healthcare costs ($24,543 versus $16,059, $8,058) than non-TRD MDD and non-MDD cohorts, respectively (all p <0.05). Risk of initial hospitalization was higher in the TRD (hazard ratio [HR] = 3.60, 95% confidence interval [CI] = 2.08-6.23) and non-TRD MDD cohorts (HR = 1.82, 95% CI = 1.02-3.25) than the non-MDD cohort.

CONCLUSIONS

The burden of MDD among older adult Medicare beneficiaries is substantial, and even greater among those with TRD compared to non-TRD MDD, demonstrating the need for more effective treatments than those currently available.

Impact of acute ethanol exposure on body temperatures in aged, adult and adolescent male rats

The mean population age of the United States continues to increase, and data suggest that by the year 2060 the population of people over the age of 65 will more than double, providing a potentially massive strain on health care systems. Research demonstrates individuals 65 and older continue to consume ethanol, often at high levels. However, preclinical animal models are still being developed to understand how ethanol might interact with the aged population. The current experiments investigated differential body temperature responses in aged rats compared to adult rats and adolescent rats. Aged (19 months of age), adult (70 days of age), or adolescent (30 days of age) male Sprague Dawley rats were administered 1.0 g/kg, 2.0 g/kg, or 3.0 g/kg ethanol, intraperitoneally (i.p.), in a balanced Latin square design. Prior to ethanol administration, a core body temperature via an anal probe was obtained, and then repeatedly determined every 60 min following ethanol exposure for a total of 360 min. In addition, a blood sample was obtained from a tail nick 60, 180, and 300 min following the ethanol injection to investigate the relationship of ethanol levels and body temperature in the same animals. Aged rats had significantly greater reductions in body temperature compared to either adult or adolescent rats following both the 2.0 g/kg and 3.0 g/kg ethanol injection. Additionally, adolescent rats cleared ethanol significantly faster than aged or adult animals. These experiments suggest body temperature regulation in aged rats might be more sensitive to acute ethanol compared to adult rats or adolescent rats. Future studies are needed to identify the neurobiological effects underlying the differential sensitivity in aged rats to ethanol.

Trends in first-time treatment admissions for older adults with alcohol use disorder: Availability of medical and specialty clinical services in hospital, residential, and outpatient facilities

BACKGROUND

Alcohol use disorder (AUD) is a growing problem among older adults. The aim of this study was to quantify trends in first-time treatment admissions for older adults with AUD in the U.S., and examine the medical and specialty clinical services offered by treatment facility type.

METHODS

Patient level data were collected from the Treatment Episode Data Set for Admissions between 2004-2017. Joinpoint regression was used to identify unique trends in first-time treatment admissions for older adults with AUD. Provider level data were collected from the National Survey of Substance Abuse Treatment Services (N-SSATS) for the most recent year, 2017. N-SSATS data were grouped by facility type (inpatient/hospital, residential, and outpatient treatment) to examine differences in medications and clinical services.

RESULTS

Among all persons seeking first-time treatment for AUD with alcohol as their primary drug of choice (n = 3,606,948), there was a significant increase in the proportion of older adults seeking treatment from 2004 to 2017 (p-trend<0.001), with an average annual percent change of 6.8% (95% confidence intervals: 6.2%-7.4%). The majority of older adults with AUD sought treatment in outpatient and residential facilities, which compared to hospital-based facilities had lower odds of offering supervised detoxification, acamprosate, naltrexone, psychiatric medications, or mental health services (all p-values<0.001). Fewer than 25% of hospital-based and 20% of residential or outpatient facilities offered specialty services for older adults.

CONCLUSIONS

U.S. substance abuse treatment providers are not compensating for the changing nature of admissions by older adults, and are not providing state of the art services for this population.

I can't drink what I used to: The interaction between ethanol and the aging brain

The population of most countries is increasing and the United Nations predicts that by the year 2050 those over the age of 60 years old will increase from 900 million individuals to approximately 2.1 billion individuals (United Nations, 2015). The increase in the number of older individuals will place a strain on many national health care systems making it important to investigate behaviors in the aged that may negatively impact general health in this demographic. Recent work has shown that older adults consume alcohol, often at levels that exceed the legal limit of intoxication. Unfortunately, consumption of high levels of ethanol in the older population is associated with many health consequences and may negatively impact the brain. Given ethical constraints found in many biomedical studies, animal models are needed to investigate the possible negative impact of high ethanol use in aged populations. However, few studies have investigated the effect of ethanol exposure in aged animals compared to ethanol exposure in younger animals and consequently the impact of ethanol in the aged population is not well understood. The current review summarizes initial work establishing the impact of ethanol in aged animals. The reviewed research studies support the working hypothesis that ethanol exposure produces significantly greater effects in aged animals compared to younger animals on many, if not all, behavioral tasks. In addition, the review proposes several initial, promising avenues of research to explore the neurobiological mechanisms that underly greater effects on ethanol-induced ataxia, cognition and sleep time. It is hoped that this effort will not only lead to a better understanding of behaviors impacted by ethanol in aged animals, but also improve the understanding brain mechanisms of the reported increased sensitivity to ethanol in the aged population.

Factors associated with elevated consumption of alcohol in older adults-comparison between China and Norway: the CLHLS and the HUNT Study

OBJECTIVES

The primary objective was to investigate the prevalence and factors associated with elevated alcohol consumption among older adults 65 years and above in China and Norway. The secondary objective was to compare the prevalence and factors in the two countries.

DESIGN

A secondary data analysis was conducted using two large cross-sectional studies (Chinese Longitudinal Healthy Longevity Survey data in 2008-2009 and Nord-Trøndelag Health Study data in 2006-2008).

PARTICIPANTS

A total of 3223 (weighted) Chinese older adults and 6210 Norwegian older adults who responded drinking alcohol were included in the analysis.

OUTCOME MEASURES

The dependent variable was elevated alcohol consumption, which was calculated as a ratio of those with elevated drinking among current drinkers. Multivariable logistic regression was used to test the dependent variable.

RESULTS

The prevalence of elevated alcohol consumption among current drinkers for the Chinese and Norwegian samples were 78.3% (weighted) and 5.1%, respectively. Being male was related to a higher likelihood of elevated alcohol consumption in both Chinese and Norwegian samples (OR=2.729, 95% CI 2.124 to 3.506, OR=2.638, 95% CI 1.942 to 3.585). Being older, with higher levels of education and a living spouse or partner were less likely to have elevated drinking in the Chinese sample (OR=0.497, 95% CI 0.312 to 0.794, OR=0.411, 95% CI 0.260 to 0.649, OR=0.533, 95% CI 0.417 to 0.682, respectively). Among Norwegian older adults, a higher level of education was related to higher likelihood of elevated drinking (OR=1.503, 95% CI 1.092 to 2.069, OR=3.020, 95% CI 2.185 to 4.175). Living in rural areas and higher life satisfaction were related to lower likelihood of elevated drinking in the Norwegian sample (OR=0.739, 95% CI 0.554 to 0.984, OR=0.844, 95% CI 0.729 to 0.977, respectively).

CONCLUSIONS

The elevated alcohol consumption patterns were strikingly different between China and Norway in regards to prevalence and socioeconomic distribution. To develop and implement culturally appropriate public health policies regarding alcohol in the future, public health policy makers and professionals need to be aware of the cultural differences and consider the demographic, social and economic characteristics of their intended population.

The impact of low to moderate chronic intermittent ethanol exposure on behavioral endpoints in aged, adult, and adolescent rats

The average age of the population in the United States and other countries is increasing. Understanding the health consequences in the aged population is critical. Elderly individuals consume ethanol, often at elevated rates, and in some cases in a binge episode. The present study sought to investigate whether binge-like ethanol exposure in aged male rats produced differential health and behavioral effects compared to adult male and adolescent male rats. Subjects were exposed to either 1.0 g/kg or 2.0 g/kg ethanol every other day via intraperitoneal injection for 20 days, and tested on a variety of behavioral measures and body weight. Binge-like ethanol exposure produced differential effects on body weight between aged and adolescent and adult rats. In addition, aged rats had a significantly longer loss of righting reflex and demonstrated a trend toward tolerance following the 2.0-g/kg exposure. No significant effects on anxiety-like behavior as measured by open arm entries, depressive-like symptoms as measured by immobility in the forced swim test, or cognitive performance as measured by latency and path length in the Morris water maze were found. These results demonstrate that aged animals are differentially sensitive to the impact of chronic intermittent ethanol exposure in some, but not all behaviors. Future research is needed to understand the mechanisms of these differential effects.

Exploring Singapore's consumption of local fish, vegetables and fruits, meat and problematic alcohol use as risk factors of depression and subsyndromal depression in older adults

Background

Depression is a chronic mental disorder that severely impacts the older adult population globally. Nutritional psychiatry is an approach that has gained traction over the years. Exploring locally relevant consumption of common types of fish, vegetables and fruits (V&F), meat and problematic alcohol use (PAU) as risk factors associated with depression and subsyndromal depression (SSD) could reveal modifiable factors that could be targeted in the local older adult population in Singapore.

Methods

Data collected from the Well-being of the Singapore Elderly (WiSE) study, a cross-sectional population-based epidemiological study of Singapore’s older adult population was analysed for the purposes of this study. Two thousand five hundred sixty-five participants were recruited and comprised of Singapore citizens and permanent residents aged ≥60 years. Data on fish, meat, and V&F consumption were collected using the sociodemographic and risk factor questionnaire. The CAGE (Cut, Annoyed, Guilt, and Eye-opener) questionnaire was used to determine PAU. The Geriatric Mental State-Automated Geriatric Examination for Computer Assisted Taxonomy (GMS-AGECAT) was used to obtain participants’ diagnosis of depression or SSD. A multinomial logistic regression was used to explore the relationship between depression and dietary factors.

Results

Consumption of V&F in the last 3 days was less likely to be associated with depression and SSD. Frequent consumption of specific species of fish was associated with depression and SSD. PAU and the frequent consumption of Himantura gerrardi (stingray) were more likely to be associated with SSD. Finally, meat consumption was more likely to be associated with depression and SSD.

Conclusions

The preliminary findings of the study support a need for healthy eating for the older adult population in Singapore. Further directions include a more thorough health and nutrition survey to capture accurate diets among the older adults in Singapore.

Alcohol-related emergency department admissions in an elderly population

OBJECTIVE

Alcohol abuse remains a major health concern. This study aimed to describe the characteristics of alcohol-related emergency department (ED) admissions in an elderly population.

METHODS

Between 1 September 2013 and 31 August 2014, we retrospectively analyzed patient charts of patients admitted with a blood alcohol concentration (BAC) of at least 0.5 g/L to the EDs of all five hospitals in two distinct areas. We focused on the population ≥65 years, divided in three subgroups (65-74, 75-84 and ≥85, respectively) and compared them to the 55-64 year group.

RESULTS

Of the 3918 included patients 645 (16.5%) were between 55 and 64, and 406 (10.4%) were ≥65 years (65-74: 267, 6.8%; 75-84: 128, 3.3%; ≥85: 11, 0.3%). The male-to-female ratio ranged between 2.1:1 and 2.7:1. BACs decreased with increasing age. In all age groups the majority of patients (71.0-77.8%) were transported by emergency medical services. The chief presenting complaint was trauma and its relative importance increased with age. Contextual factors consisted mostly of chronic abuse (43.1-57.8%). Most frequently patients could be discharged within 24 h, although hospital admission rates increased with age.

CONCLUSION

Our study shows that alcohol-related ED admissions in the elderly are common, but less frequent than in younger age groups. More (preferentially prospective) studies are needed to give more insight in the living environment, prescription medication, socioeconomic cost, etc. Nonetheless, it is clear that a national action plan should be developed to tackle the alcohol abuse problem in all age groups.

Critical Evaluation of the Association Between Elevated Mean Corpuscular Volume and Alcohol-Related Traffic Accidents: A Retrospective Study on 6244 Car Crash Cases

BACKGROUND

Erythrocyte mean corpuscular volume (MCV) has been used for decades as a biomarker of chronic alcohol abuse and in the treatment of alcohol dependence. More recently, it has also been adopted to investigate the fitness of subjects to hold the driving license to prevent traffic accidents. So far, however, the studies on the association of MCV with an increased risk of alcohol-associated car accidents are extremely scarce, if not totally absent. To the best of our knowledge, the present work is the first specifically aimed at studying a plausible association between elevated MCV and crash accidents correlated with alcohol abuse.

METHODS

A total of 6,244 drivers involved in traffic accidents underwent mandatory laboratory analyses including blood alcohol concentration (BAC) determination and MCV analysis. BAC and MCV determinations were performed by headspace gas chromatography and complete blood count, respectively.

RESULTS

The chi-square test evaluating the proportions of subjects with elevated MCVs (>95 fl) yielded a highly significant result (χ²  = 68.0; p < 0.001) in the blood samples where the BAC was above the legal limit (i.e., >0.5 g/l). However, when considering only drivers showing BACs in the range of 0.51 to 1.5 g/l, the frequencies of elevated MCV values are fairly comparable (χ²  = 0.062, p = 0.80). In contrast, limiting the evaluation to BACs > 1.5 g/l, the frequency of elevated MCVs raised to 19.1% (χ²  = 58.9, p value < 0.001 vs. the group with BAC within the legal limits).

CONCLUSIONS

The present observations show that MCV increases are typically associated with drivers involved in accidents only if driving under severe alcohol intoxication, leading to a preliminary conclusion that, in the context of the certification of the fitness to the driving license, MCV fails to reveal individuals at risk who tend to drive in a condition of low-to-moderate alcohol intoxication.

Applications of Pueraria lobata in treating diabetics and reducing alcohol drinking

Pueraria lobata is one of the most important medicinal herbs used traditionally in China. According to Shanghan Lun (Treatise on Exogenous Febrile Disease), it has been used traditionally to relieve body heat, eye soring, dry mouth, headache associated with high blood pressure, and stiff neck problems. Modern studies in the 1970s revealed that isoflavonoids extracted from P. lobata were the bioactive components of an herbal remedy namely Yufeng Ningxin Tablets for the treatment of patients after stroke. This article reviews recent application of P. lobota in the treatment of diabetics and in reducing alcohol drinking. In view of its low toxicity profile, P. lobota stands an excellent chance to be developed as a phytomedicine for treating human diseases.

Detection of alcohol abuse in older patients with cancer: The integration of alcohol screening questionnaires in the comprehensive geriatric assessment

OBJECTIVES

We aimed to evaluate the feasibility of implementing an alcohol screening questionnaire as part of the comprehensive geriatric assessment (CGA) by reporting the prevalence of alcohol abuse in a group of older patients with cancer in a Belgian cancer centre.

MATERIALS AND METHODS

Patients were recruited at the Geriatric Oncology Clinic of the Kortrijk Cancer Centre and were evaluated by use of a CGA. Two alcohol screening questionnaires were integrated into the CGA: the Cutdown-Annoyed-Guilty-Eye-opener (CAGE) questionnaire and the Alcohol Use Disorders Identification Test-screening version (AUDIT-C).

RESULTS

193 patients with a mean age of 77.7 years were included in the analyses. Abnormal scores on the CAGE were detected in 6.3% of males and 1.2% of women. Abnormal results on the AUDIT-C were noticed in 30.0% of men, and in 21.7% of women. A regression analysis could not find a significant effect of the CAGE questionnaire when entered as predictor for CGA domain scores. Regarding the AUDIT-C, significant results were detected for predicting the score of the Geriatric-8 questionnaire and polypharmacy in men, and the Independent Activities of Daily Living questionnaire in women. No association with one-year survival was detected for either alcohol screening questionnaire.

DISCUSSION

It is feasible to implement an alcohol screening questionnaire as part of a CGA as results indicated a rather high level of alcohol abuse in this cohort.

Liver diseases in the elderly

Due to the progressive increase in life expectancy, the number of elderly people in the world is growing rapidly. Although there are no liver diseases specific of older age, the ageing liver shows some anatomical and physiological changes that can affect the frequency and the clinical behavior of most hepatopathies. In particular, these changes tend to cause an increased vulnerability to acute liver injury and an increased susceptibility to liver fibrosis, accounting for the predisposition to a generally more severe course of liver diseases compared to younger patients. Furthermore, advanced age is also associated with immune system alterations, influencing the manifestation of those hepatopathies that are mediated by host immune response, like viral hepatitis, autoimmune hepatitis but also hepatocellular carcinoma. Despite these changes, total liver function and laboratory values tend to be well maintained in healthy elderly, so that every enzymatic alteration in a geriatric patient should be investigated with the same attention as in a younger one. A proper and early diagnosis is of great importance both considering the age-related more aggressive course of hepatopathies and that age itself does not seem to be a limit for most treatment options, even if specific data are often lacking. This paper focuses on the peculiarities of main liver diseases in geriatrics, with respect to epidemiology, clinical presentation, diagnosis and management, which can be more challenging in advanced age because of the frequent comorbidities and polytherapies.

Religiosity and Alcohol Use: Is Religiosity Important for Abstention and Consumption Levels in the Second Half of Life?

OBJECTIVE

The aim of this study was to investigate the relative role of religiosity for alcohol abstention and consumption levels among individuals aged 40 years or above.

METHOD

A two-wave prospective survey was conducted among Norwegians aged 40 to 80 years (Time 1 in 2002/2003, and Time 2 in 2007/2008). The analytical sample of this study constituted those who responded to the questionnaire survey at both time points (n = 2671).

RESULTS

The findings showed that religiousity was strongly associated with abstention and less consumption while adjusting for demographics and health variables. The results also reflected that females and those with higher age were more likely to abstain from alcohol than males and those with lower age, respectively. Individuals with high education were less likely to abstain than those with basic education. Females and those with high age also reflected less alcohol consumption than males and individuals of lower age, respectively. Further, people who were married or with a registered partner consumed less alcohol than people who were not married or with a registered partner. High education and good physical health was associated with higher consumption. The main results were consistent across prospective and cross-sectional models.

CONCLUSION

Religiosity seems to be important both for abstention and alcohol consumption levels in the second half of life.

DSM-5 alcohol use disorder features among treatment-seeking older adults

Abstract. Background: The number of older adults with alcohol use disorder (AUD) is expected to rise. Adapted treatments for this group are lacking and information on AUD features in treatment seeking older adults is scarce. The international multicenter randomized-controlled clinical trial “ELDERLY-Study” with few exclusion criteria was conducted to investigate two outpatient AUD-treatments for adults aged 60+ with DSM-5 AUD. Aims: To add to 1) basic methodological information on the ELDERLY-Study by providing information on AUD features in ELDERLY-participants taking into account country and gender, and 2) knowledge on AUD features in older adults seeking outpatient treatment. Methods: baseline data from the German and Danish ELDERLY-sites (n=544) were used. AUD diagnoses were obtained with the Mini International Neuropsychiatric Interview, alcohol use information with Form 90. Results: Lost control, desired control, mental/physical problem, and craving were the most prevalent (> 70 %) AUD-symptoms. 54.9 % reported severe DSM-5 AUD (moderate: 28.2 %, mild: 16.9 %). Mean daily alcohol use was 6.3 drinks at 12 grams ethanol each. 93.9 % reported binging. More intense alcohol use was associated with greater AUD-severity and male gender. Country effects showed for alcohol use and AUD-severity. Conclusion: European ELDERLY-participants presented typical dependence symptoms, a wide range of severity, and intense alcohol use. This may underline the clinical significance of AUD in treatment-seeking seniors.

Different patterns of alcohol consumption and the incidence and persistence of depressive and anxiety symptoms among older adults in Ireland: A prospective community-based study

BACKGROUND

The associations of different patterns of alcohol consumption and the incidence and persistence of depressive and anxiety symptoms in older age remain unclear.

METHODS

Data on 6095 adults aged ≥ 50 years old from the Irish Longitudinal Study on Aging (TILDA) was analyzed. Participants completed the CAGE instrument to screen for problematic alcohol use at baseline between October 2009 and February 2011. Outcomes were incident (assessed by the CES-D scale) and anxiety (assessed by the Hospital Anxiety and Depressive scale) symptoms after a two-year follow-up as well as persistence of probable depression and anxiety among those with a positive screen for those disorders at baseline. Associations were adjusted for potential confounders through multivariable models.

RESULTS

In the overall sample, problem drinking did not predict incident and persistent depression and anxiety in this sample. Among females, problem drinking increased the risk for incident depression (OR = 2.11; 95%CI = 1.12-4.00) and anxiety (OR = 2.22; 95%CI = 1.01-4.86). In addition, problem drinking increased the risk of persistent depressive symptoms (OR = 2.43; 95%CI = 1.05-5.06) among females.

CONCLUSION

Problem drinking may increase the risk of incident probable depression and anxiety among older females. Furthermore, problem drinking led to a higher likelihood of persistent depressive symptoms in older female participants. Interventions targeting problem drinking among older females may prevent the onset and persistence of depression in this population, while also decreasing the incidence of anxiety symptoms.
