The rates of middle molecules in the blood in rats with different motor activity in alcoholic and non alcoholic exerimental hepatosis

Alcohol use disorders affect millions of individuals worldwide. The impact of these facts lies in the elevated social and economic costs. Liver metabolizes 75-98 % of ethanol that enters the organism. If the level of alcohol in the liver cells exceeds its degradation rate, alcoholic liver disease develops. The aim of the study was to determine the peculiarities of hepatotoxicity after simulation of of ethanol hepatosis and non-alcoholic steatohepatitis of high and low-motor active rats. Material and methods of investigation. The experiments were performed on on 72 white outbred male rats. The animals were divided into three groups: control, non-alkoholic hepatitis (NAH), ethanol hepatosis (EH). Each of group was subdivided – animals with high and low-motor activity (HA and LA). Contents of middle-mass molecules (MMM) were determined in the blood serum. Results. The analysis of the results shows that the levels of MMM in blood serum are increasing. Dystrophic changes that appear in a consequence of hypoxia are noted in NAH and EH. Both morphological and biochemical changes were more significant in HA animals. The degree of MMM accumulation depends on the severity of the pathology and motor activity of the animals. Less activity of MMM238 is observed in HA rats, which can be explained by the development of multi-organ pathology. Conclusions. During our investigations it was found the significant increasing of MMM levels in blood serum in rats with ethanol hepatosis and nonalkoholic hepatitis. The accumulation of MMM is not only a marker of endotoxication, they also increase the course of the pathological process, acquiring the roles of secondary toxins, affect the viability of all organs and systems. The degree of MMM accumulation depends on the moto activity of the animals and simulated pathology and is more significant in highly active animals, compared with low-active in the ethanol using. Less activity of MMM238 is observed in HA rats with EH, which can be explained by the development of multi-organ pathology, in particular, renal impairment. Morphological investigations showed that the grade of liver injury was more significant in HA rats.

Evaluation of alcohol consumption motivation: psychometric properties of the Alcohol Consumption Motivation Inventory by V.Yu. Zavyalov

The alcohol consumption motivation inventory (ACM) was developed by V.Yu. Zavyalov. Now it is a widespread psychometric tool in research and clinical practice for the evaluation of alcohol consumption motivation in Russian-speaking patients with alcohol use disorders. The aim of the study is to analyze the psychometric properties of the ACM inventory. Results show that the factor structure of the ACM inventory significantly differs from the one stated in the original. The results of the statistical analysis allowed three significant clusters. Cluster A was composed of the scales of the conditioned triad—traditional, submissive, and pseudo-cultural motives. This cluster also partially included hedonistic motives and self-harm motives. Cluster B was composed of scales of personal and pathological triads—withdrawal, ataractic and hyperactivational motives. Hedonistic motives and addictive motives were also partially included. Cluster B included self-harm motives and hangover (addictive) motives. According to the data obtained, the ACM inventory cannot measure an alcohol consumption motivation in the way of the original method. Future work on the modification of the ACM inventory should be based on the results obtained recently in neurophysiological and clinicalpsychopharmacological studies in the field of motivation for alcohol consumption, and includes the revision of the items of the questionnaire, a statistically substantiated gradation of levels for assessing the effectiveness of the motives for alcohol use, and the validation of the version of the ACM questionnaire in women sample.

Repetitive negative thinking: transdiagnostic correlate and risk factor for mental disorders? A proof-of-concept study in German soldiers before and after deployment to Afghanistan

Background and objectives Disorder-specific forms of Repetitive Negative Thinking (RNT) are associated with multiple diagnostic categories, indicating a transdiagnostic nature. Few studies examined content-independent RNT processes across groups of diagnosed mental disorders. Moreover, theory describes RNT processes as critically involved in the etiology of mental disorders, empirical evidence however is scarce. We first tested the transdiagnostic nature by examining levels of RNT across groups of internalizing and externalizing mental disorders compared to healthy individuals and explored RNT levels in a comorbid disorder-group. Second, we examined whether RNT predicts incident psychopathology. Methods In a sample of German soldiers (n = 425) scheduled for deployment in Afghanistan, we compared RNT levels between diagnosed groups with alcohol use disorders, anxiety disorders and healthy individuals cross-sectionally. Exploratory analyses were conducted comparing a comorbid disorder-group to healthy individuals and to both single-disorder-groups. Longitudinally, we examined the predictive value of pre-deployment RNT levels for incident psychopathology after deployment (n = 167). RNT was measured using the Perseverative Thinking Questionnaire (PTQ), DSM-IV diagnoses were assessed using the standardized Composite International Diagnostic Interview (CIDI). Results Cross-sectional comparisons revealed that soldiers with alcohol use disorders and anxiety disorders showed significantly higher degrees of RNT compared to healthy soldiers. RNT levels in those with comorbid disorders were significantly higher compared to healthy soldiers but also compared to both single-disorder-groups. Longitudinal analyses revealed that higher levels of RNT prior to deployment were associated with a higher risk to have any incidental mental disorder after deployment. This however is only attributable to individuals with a PTQ score above a cut-off of 15. Conclusions Findings provide evidence for RNT as a transdiagnostic correlate and a vulnerability factor for the development of mental disorders.
