RESUMO
AIMS: While clinical consequences of thiamine deficiency in alcohol use disorder (AUD) are severe, evidence-based recommendations on dosage, type of administration and duration of thiamine substitution (TS), and its' target levels remain sparse. This study aimed to compare the effect of two best practice TS regimens on thiamine blood levels (i.e. thiamine pyrophosphate, TPP) and cognitive function. METHODS: In 50 patients undergoing in-patient alcohol-withdrawal treatment, TPP levels were determined at baseline and end of weeks 1, 2 and 8 following administration of oral TS (3 × 100 mg/day for 7 days followed by 1 × 100 mg/day thereafter) either with or without preceding intravenous TS (3 × 100 mg/day for 5 days). An extensive psychiatric assessment was conducted at baseline, including an evaluation of AUD severity and depressive symptoms. Additionally, cognitive function and depressive symptoms were repeatedly evaluated. RESULTS: Relevant increases (mean increase by 100.2 nmol/l [CI 76.5-123.8], P < 0.001) in peripheral blood TPP levels were observed in all patients at the end of weeks 1 and 2. Furthermore, no relevant difference between the intravenous and the oral group was found (average difference between increases: 2.3 nmol/l, P = 0.912). Importantly, an association between the 'extent of the response' to TS and the performance in a memory task was revealed in secondary analyses. CONCLUSION: TS was associated with improving cognitive function in patients with AUD, independently of the substitution regime. Thus, in clinical practice, oral TS might be a sufficient but obligatory medication to prevent cognitive decline in AUD in the absence of Wernicke-Korsakoff Syndrome.

Alcohol-related dementia (ARD) is a common and severe co-morbidity in alcohol use disorder (AUD). We propose brain iron overload (BIO) to be an important and previously neglected pathogenic process, accelerating cognitive decline in AUD. Furthermore, we suggest thiamine, which is frequently depleted in AUD, to be a key modulator in this process: Thiamine deficiency impairs the integrity of the blood-brain barrier, thereby enabling iron to pass through and accumulate in the brain. This hypothesis is based on findings from animal, translational, and neuroimaging studies, discussed in this article. To validate this hypothesis, translational studies focusing on brain iron homeostasis in AUD, as well as prospective clinical studies investigating prevalence and clinical impact of BIO in AUD, should be conducted. If proven right, this would change the understanding of ARD and may lead to novel therapeutic interventions in prevention and treatment of ARD.

BACKGROUND: Suicide rates are known to be increased in patients after discharge from in-patient psychiatric treatment. However, evidence on risk factors for suicide within this patient group are contradictory. Thus, this study aims to investigate suicide after discharge from a sizeable psychiatric care facility to determine associated risk factors. METHODS: Data on individual patient level from a 15-year single-centre cohort were linked to data from the national death registry and cumulative incidence rates were calculated applying competing risk models. Independent variables included the patients' sex, age at admission, diagnosis, and length of admission. For each of these factors, subdistribution hazards ratios were calculated using a Fine-Gray model. RESULTS: In our sample of 18,425 discharges, when using patients with the diagnosis of substance-use-disorders as a comparator, a significant increase in hazard of post-discharge suicide for male sex (SHR = 1.67;p = 0.037) as well as the discharge diagnoses of affective disorders (SHR = 3.56;p = 0.017) and neurotic stress and somatoform disorders (SHR = 3.73;p = 0.024) were found. Interestingly, the hazard of suicide significantly decreased in more recent discharges (SHR = 0.93;p = 0.006). No statistically significant association of the length of admission with the suicide risk was found (SHR = 0.98;p = 0.834). LIMITATIONS: Suicides may have been mis-identified as natural death in the national death register. CONCLUSION: Male sex and distinct diagnoses were associated with an increased risk for suicide after discharge from a psychiatric care institution. The markedly increased suicide risk within this patient collective highlights the need for the development of tools to assess suicidal behaviour in this group of patients reliably.

Alcohol use disorder (AUD) is one of the most important risk factors for the development of alcohol-related liver cirrhosis (ALC). Importantly, psychiatrists are an integral part of the interdisciplinary care for patients with AUD and ALC. The aim of the current study was to investigate whether sex influences the outcome within this group of patients. For this purpose, data of all registrations for liver transplantations due to ALC within the Eurotransplant region from 2010 to 2019 were analyzed for sex disparities using competing risk models and in-between group comparisons. Relevant sex differences in registration numbers (24.8% female) and investigated outcomes were revealed. Risk ratios for a positive outcome, i.e., transplantation (0.74), and those of adverse outcomes, i.e., removal from waiting list (1.44) and death on waiting list (1.10), indicated a relative disadvantage for female patients with ALC. Further, women listed for liver transplantations were significantly younger than their male counterparts. Notably, sex disparities found in registration and outcome parameters were independent of differences found in the prevalence of AUD and liver transplantations. Further research is necessary to identify the underlying mechanisms and establish strategies to ensure equity and utility in liver transplantations due to ALC.
RESUMO
BACKGROUND: Prevalence of cognitive decline and dementia is rising globally, with more than 10 million new cases every year. These conditions cause a significant burden for individuals, their caregivers, and health care systems. As no causal treatment for dementia exists, prevention of cognitive decline is of utmost importance. Notably, alcohol is among the most significant modifiable risk factors for cognitive decline. METHODS: Longitudinal data across 15 years on 6,967 individuals of the Survey of Health, Ageing and Retirement in Europe were used to analyze the effect of alcohol consumption and further modifiable (i.e., smoking, depression, and educational obtainment) and non-modifiable risk factors (sex and age) on cognitive functioning (i.e., memory and verbal fluency). For this, a generalized estimating equation linear model was estimated for every cognitive test domain assessed. RESULTS: Consistent results were revealed in all three regression models: A nonlinear association between alcohol consumption and cognitive decline was found-moderate alcohol intake was associated with overall better global cognitive function than low or elevated alcohol consumption or complete abstinence. Furthermore, female sex and higher educational obtainment were associated with better cognitive function, whereas higher age and depression were associated with a decline in cognitive functioning. No significant association was found for smoking. CONCLUSION: Our data indicate that alcohol use is a relevant risk factor for cognitive decline in older adults. Furthermore, evidence-based therapeutic concepts to reduce alcohol consumption exist and should be of primary interest in prevention measures considering the aging European population.

BACKGROUND: Alcohol use disorder (AUD) is associated with a high prevalence rate and causes a significant burden on health systems globally. The most severe condition associated with AUD is end-stage alcohol-related liver disease (ARLD), for which liver transplantation (LTX) is the only curative therapy. However, the determination of key epidemiologic figures of both conditions is limited by several difficulties and challenges. Therefore, the goal of this paper is to discuss different epidemiological models to estimate AUD and ARLD prevalence, and compare the results of these models with LTX data. METHODS: A literature search for epidemiological models estimating the prevalence of AUD and associated secondary diseases was conducted. Identified approaches are discussed and recalculated, applying the newest available data for Austria. The thus estimated numbers were, in a further step, set in relation to the national LTX statistics. RESULTS: Besides health survey-based estimations and models based on economic data, estimations based on the mortality of ARLD (Jellinek formula) were identified. Depending on the prediction scenario, the calculated rates of prevalence of AUD ranged between 4.1% and 10.1% for the population aged older than 15 years. Furthermore, while the prevalence of secondary diseases due to AUD is high, only a marginal proportion (about 4%) of end-stage ARLD patients receive a new organ. CONCLUSION: These results suggest that the prevalence of AUD and associated diseases remain underestimated. Furthermore, a pronounced discrepancy between the number of ARLD deaths and the number of LTXs due to ARLD, and distinct regional differences in the supply of LTXs, were found.

The potentially deleterious and teratogen effects of alcohol consumption during pregnancy are an important medical as well as socio-economic topic. Maintaining the necessary strict abstinence is especially challenging for pregnant women diagnosed with alcohol dependence. Due to limited data, optimal pharmacological treatment is seldom possible. Importantly, all substances currently approved for relapse prevention are contraindicated during pregnancy. Limited data concerning the off-label-use of Ondansetron (5-HT3 receptor antagonist) as relapse prevention during pregnancy exists. In the portrayed case-report, a pregnant patient received psychopharmacological treatment with Sertraline, Quetiapine and Ondansetron. Under this established pharmacological therapy, the patient achieved abstinence for the remainder of the pregnancy.

BACKGROUND: Older adults exhibit heightened vulnerability for alcohol-related health impairments. Increases in the proportion of older adults within the European Union's total population and prevalence rates of alcohol use disorders in this age group are being observed. This large scale international study was conducted to identify those older adults with an increased risk to engage in hazardous drinking behaviour. METHODS: Socio-demographic, socio-economic, personality characteristics (Big Five Inventory, BFI-10), and alcohol consumption patterns of 13,351 individuals from 12 different European countries, collected by the Survey of Health, Aging, and Retirement in Europe, were analyzed using regression models. RESULTS: Age, nationality, years of education, as well as personality traits, were significantly associated with alcohol intake. For males, extraversion predicted increased alcohol intake (RR = 1.11, CI = 1.07-1.16), whereas conscientiousness (RR = 0.93, CI = 0.89-0.97), and agreeableness (RR = 0.94, CI = 0.90-0.99), were associated with a reduction. For females, openness to new experiences (RR = 1.11, CI = 1.04-1.18) predicted increased alcohol intake. Concerning excessive drinking, personality traits, nationality, and age-predicted consumption patterns for both sexes: Extraversion was identified as a risk factor for excessive drinking (OR = 1.15; CI = 1.09-1.21), whereas conscientiousness was identified as a protective factor (OR = 0.87; CI = 0.823-0.93). CONCLUSION: Hazardous alcohol consumption in the elderly was associated with specific personality characteristics. Preventative measures, crucial in reducing deleterious health consequences, should focus on translating the knowledge of the association of certain personality traits and alcohol consumption into improved prevention and treatment.

BACKGROUND: This study aimed to provide an extensive and up-to-date analysis of running-related injuries (RRI) and analyze a broad range of contributing factors for a large heterogeneous and non-selected running population from Central Europe. METHODS: Anthropometric, training, footwear, anatomic malalignment, and injury data from 196 injured runners were assessed case-controlled and retrospectively. Univariate and multivariate regression models were developed to identify associated factors for specific injury locations and diagnoses. RESULTS: The majority of patients were female (56%). Three most frequently observed malalignments included varus knee alignment, pelvic obliquity, and patellar squinting. The most common injuries were the patellofemoral pain syndrome (PFPS), the iliotibial band friction syndrome (ITBFS), patellar tendinopathy, spinal overload, and ankle instability. A number of contributing factors were identified. Previous injury history was a contributing factor for knee injuries and ITBFS. Lower training load was reported with a higher incidence of PFPS, while a higher training load was positively associated with injuries of the lower leg. Runners with a higher body mass index (BMI) were at a significantly higher risk for lower back injuries. CONCLUSIONS: Running-related injuries are multifactorial associated with a combination of variables including personal data, training load, anatomic malalignments, and injury history. They can furthermore result from a lack of experience/training as well as from overuse. Suffering a specific RRI of high risk could be defined based on individual predispositions and help to induce appropriate training balance.
RESUMO
BACKGROUND: Suicide risk in patients is markedly elevated during psychiatric inpatient care, as well as after discharge. However, it is unclear whether, and to what extent, this increased suicide risk varies between sex. Thus, the aim of this study was to analyze sex differences for suicides during and after psychiatric hospitalization in various countries. METHODS: National suicide mortality rates and inpatient-related suicide rates (three intervals: during psychiatric inpatient treatment, 1 month, and 1 year after discharge) from 12 countries for 2000-2016 were analyzed, and a logistic model was used to quantify the effect of sex. RESULTS: Persons admitted to or discharged from psychiatric inpatient care exhibited significantly increased rates of suicide compared to those in the general population. Furthermore, increase of suicide risk was significantly higher for females than for males for all investigated time intervals (inpatient suicide odds ratio [OR] 1.85; suicide within 1 month after discharge-OR 1.94; suicide within 1 year after discharge-OR 2.04). CONCLUSION: Analysis confirmed the time during and after psychiatric inpatient care to be significantly associated with an elevated risk for suicide. Further, a significant sex effect was observed, with females in this population being at a proportionally higher risk for suicide during psychiatric inpatient treatment as well as the year following discharge. Our study implicates that more effective suicide preventive measures during inpatient stay, focusing on female patients, are needed.

This case report is about a 44-year-old woman with alcohol-related end-stage liver disease. Initial contact with the patient was made in the alcohol-outpatient clinic of the Department of Psychiatry and Psychotherapy, Clinical Division of Social Psychiatry, Medical University of Vienna. Due to a particularly poor general condition, Child Pugh Score C/MELD Score 20, the patient was admitted to ward 4A, with the clinical and scientific focus of treating patients with alcohol use disorder. The withdrawal process was complicated by a multitude of factors associated with end-stage liver disease. By explaining the theoretical background of possible somatic as well as psychiatric complications of end-stage liver disease and elaborating on treatment options a comprehensive overview of the psychiatric and somatic management of this patient population is given.
