Alkoholi ja narkootikumide tarbimisharjumused prognoosivad suitsiidi

Uuringus võrreldi suitsidentide joobnustavate ainete tarbimisharjumusi kontrollrühmaga lähtuvalt soost, vanusest ja rahvusest. Uuringu tulemused näitasid, et Eesti suitsidentide hulgas olid 59,8% alkoholisõltlased ja kuritarvitajad ning 5,3% narkootikumide kuritarvitajad. Suitsidentidel oli oluliselt suurem risk olla alkoholisõltlane ja narkootikumide kuritarvitaja võrreldes kontrollrühmaga

Association of the COMT Val108/158Met genotype with professional career and education: The Val-allele is more frequent in managers and in enterprising occupations

Catechol-O-methyl transferase (COMT) is a key player in neurotransmission by catecholamines, and the functional COMT Val108/158Met polymorphism is strongly related to prefrontal reactivity and to dopamine levels. As dopamine is a critically important neurotransmitter in cognition, emotion and motivation, we addressed the potential impact of this genotype on life course by examining its association with being in enterprising professions. The parents (n = 1410) of the target subjects in the Estonian Children Personality Behaviour and Health Study reported their current occupation, and those classified as enterprising (n = 197; 18%) were compared with the remaining group. Additionally, the subjects self-classified themselves according to the International Standard Classification of Occupations and the group of managers (6.2%) was compared to other groups. We found that the COMT Val108/158Met Val/Val homozygotes were overrepresented among enterprising occupations and the Val-allele carriers among self-classified managers. While several measures associated with the Val/Val homozygosity were also associated with enterprising occupation, no simple path from the genotype to enterprising occupations emerged from structural equation models, suggesting that the COMT Val108/158Met genotype contributes to choices of profession via multiple interactive features. We also reproduced a previous finding that the COMT genotype is associated with educational attainment in a gender-dependent manner

Variants of the aggression-related RBFOX1 gene in a population representative birth cohort study: aggressiveness, personality and alcohol use disorder

Background: Recently, RBFOX1, a gene encoding an RNA binding protein, has consistently been associated with aggressive and antisocial behavior. Several loci in the gene have been nominally associated with aggression in genome-wide association studies, the risk alleles being more frequent in the general population. We have hence examined the association of four RBFOX1 single nucleotide polymorphisms, previously found related to aggressive traits, with aggressiveness, personality, and alcohol use disorder in birth cohort representative samples. Methods: We used both birth cohorts of the Estonian Children Personality Behavior and Health Study (ECPBHS; original n = 1,238). Aggressiveness was assessed using the Buss-Perry Aggression Questionnaire and the Lifetime History of Aggressiveness structured interview at age 25 (younger cohort) or 33 (older cohort). Big Five personality at age 25 was measured with self-reports and the lifetime occurrence of alcohol use disorder assessed with the MINI interview. RBFOX1 polymorphisms rs809682, rs8062784, rs12921846, and rs6500744 were genotyped in all participants. Given the restricted size of the sample, correction for multiple comparisons was not applied. Results: Aggressiveness was not significantly associated with the RBFOX1 genotype. RBFOX1 rs8062784 was associated with neuroticism and rs809682 with extraversion. Two out of four analyzed RBFOX1 variants, rs8062784 and rs12921846, were associated with the occurrence of alcohol use disorder. Conclusions: In the birth cohort representative sample of the ECPBHS, no association of RBFOX1 with aggressiveness was found, but RBFOX1 variants affected basic personality traits and the prevalence of alcohol use disorder. Future studies on RBFOX1 should consider the moderating role of personality and alcohol use patterns in aggressiveness

Gastrointestinal failure in intensive care: a retrospective clinical study in three different intensive care units in Germany and Estonia

BACKGROUND: While gastrointestinal problems are common in ICU patients with multiple organ failure, gastrointestinal failure has not been given the consideration other organ systems receive. The aim of this study was to evaluate the incidence of gastrointestinal failure (GIF), to identify its risk factors, and to determine its association with ICU mortality. METHODS: A retrospective analysis of adult patients (n = 2588) admitted to three different ICUs (two ICUs at the university hospital Charité-Universitätsmedizin Berlin, Germany and one at Tartu University Clinics, Estonia) during the year 2002 was performed. Data recorded in a computerized database were used in Berlin. In Tartu, the data documented in the patients' charts was retrospectively transferred into a similar database. GIF was defined as documented gastrointestinal problems (food intolerance, gastrointestinal haemorrhage, and/or ileus) in the patient data at any period of their ICU stay. ICU mortality, length of stay, and duration of mechanical ventilation were assessed as outcome parameters. RESULTS: GIF was identified in 252 patients (9.7% of all patients). Only 20% of GIF patients were identifiable at admission. GIF was related to significantly higher mortality (43.7% vs. 5.3% in patients without GIF), as well as prolonged length of ICU stay (10 vs. 2 days) and mechanical ventilation (8 vs. 1 day), p < 0.001, respectively. Patients' profile (emergency surgical or medical), APACHE II and SOFA scores and the use of catecholamines at admission were identified as independent risk factors for the development of GIF. Development of GIF during ICU stay was an independent predictor for death. CONCLUSION: Gastrointestinal failure represents a relevant clinical problem accompanied by an increased mortality, longer ICU stay and mechanical ventilation

Suicidal thoughts and depressive feelings amongst Estonian schoolchildren: effect of family relationship and family structure

Depressive feelings and suicidal ideation in a non-clinical sample of adolescents in Estonia were analysed in the context of family structure, mutual relationships amongst family members and schoolchildren's preferences regarding intimate personal contacts with particular family members. Data from the WHO collaborative study 'Health Behaviour in School-aged Children 2005/2006' (HBSC) were used. A representative sample of schoolchildren aged 11, 13 and 15 years completed the semi-structured questionnaire. The analyses included only adolescents living in households with at least one birth parent. The subjects were 4,389 schoolchildren (2,178 boys and 2,211 girls), who were divided into three groups based on: (1) suicidal thoughts, with or without depressive feelings; (2) depressive feelings; and (3) neither suicidal thoughts nor depressive feelings. Multinomial logistic regression was used. The proportion of depressive feelings increased with age for both boys and girls. Girls expressed depressive feelings more frequently than boys from ages 13 and 15 years, and suicidal thoughts from age 15 years. Self-reported satisfaction with relationships in the family reduced the likelihood of depressive feelings and suicidal thoughts. Good communication with the parents reduced the likelihood of suicidal thoughts in all age groups. Adolescents who were satisfied with their family relationships suffered less frequently from depressive feelings and suicidal thoughts. The best environment for an adolescent was a family with both birth parents. Of the adolescents in 'non-intact' families, those with a step-parent in the family showed suicidal thoughts more frequently than those in single-parent families. Associations between family-related variables and suicidal thoughts were significant even after adjusting for family economic deprivation score

Associations between quality of relationships and life satisfaction of older mothers in Estonia, Germany, Russia and China

The aim of the current study is to examine the associations between the quality of relationships and life satisfaction of older mothers in Estonia, Germany, Russia and the People's Republic of China, based on the assumptions of the Family Change Theory. The role of satisfaction with family life as the probable mediating factor is considered. Estonian older mothers reported the least admiration and intimacy in their relationships with their adult daughters, and the least satisfaction with family life compared to German, Russian and Chinese mothers. German older mothers perceived the most admiration from their adult daughters and were the most satisfied with both their family and general life. Russian older mothers were the least satisfied with their general life compared to their counterparts in Estonia, Germany and China. The results from the Structural Equation Modelling showed that the relationship between satisfaction with family life and general life satisfaction was statistically significant in all countries except Russia. The satisfaction with family life as a mediating factor might strengthen the positive and negative aspects of intergenerational relationships on the life satisfaction of older mothers. The findings indicated that the emotional closeness and intergenerational relationships in families during the process of transition and globalisation play an important role in the life satisfaction of older mothers in these four countries.publishe
