EPA guidance on mental health and economic crises in Europe.

This European Psychiatric Association (EPA) guidance paper is a result of the Working Group on Mental Health Consequences of Economic Crises of the EPA Council of National Psychiatric Associations. Its purpose is to identify the impact on mental health in Europe of the economic downturn and the measures that may be taken to respond to it. We performed a review of the existing literature that yields 350 articles on which our conclusions and recommendations are based. Evidence-based tables and recommendations were developed through an expert consensus process. Literature dealing with the consequences of economic turmoil on the health and health behaviours of the population is heterogeneous, and the results are not completely unequivocal. However, there is a broad consensus about the deleterious consequences of economic crises on mental health, particularly on psychological well-being, depression, anxiety disorders, insomnia, alcohol abuse, and suicidal behaviour. Unemployment, indebtedness, precarious working conditions, inequalities, lack of social connectedness, and housing instability emerge as main risk factors. Men at working age could be particularly at risk, together with previous low SES or stigmatized populations. Generalized austerity measures and poor developed welfare systems trend to increase the harmful effects of economic crises on mental health. Although many articles suggest limitations of existing research and provide suggestions for future research, there is relatively little discussion of policy approaches to address the negative impact of economic crises on mental health. The few studies that addressed policy questions suggested that the development of social protection programs such as active labour programs, social support systems, protection for housing instability, and better access to mental health care, particularly at primary care level, is strongly needed.

EPA guidance on how to improve the image of psychiatry and of the psychiatrist.

Stigma against mental illness and the mentally ill is well known. However, stigma against psychiatrists and mental health professionals is known but not discussed widely. Public attitudes and also those of other professionals affect recruitment into psychiatry and mental health services. The reasons for this discriminatory attitude are many and often not dissimilar to those held against mentally ill individuals. In this Guidance paper we present some of the factors affecting the image of psychiatry and psychiatrists which is perceived by the public at large. We look at the portrayal of psychiatry, psychiatrists in the media and literature which may affect attitudes. We also explore potential causes and explanations and propose some strategies in dealing with negative attitudes. Reduction in negative attitudes will improve recruitment and retention in psychiatry. We recommend that national psychiatric societies and other stakeholders, including patients, their families and carers, have a major and significant role to play in dealing with stigma, discrimination and prejudice against psychiatry and psychiatrists.

Association between metabolic syndrome and pelvic organ prolapse severity.

INTRODUCTION AND HYPOTHESIS: As in the case of cardiovascular and metabolic diseases, the prevalence of pelvic organ prolapse (POP) has been rising with the increasing proportion of elderly women in the population. The purpose of the present cross-sectional study was to evaluate the components of metabolic syndrome (MS) in urogynecological patients with a variable POP severity. METHODS: The MS risk factors (elevated waist circumference, elevated triglycerides, decreased high-density lipoprotein cholesterol, elevated blood pressure, hyperglycemia) were assessed in 100 women who were referred to our urogynecological center with pelvic floor disorders (PFD). POP was evaluated with the Pelvic Organ Prolapse Quantification system (POP-Q). RESULTS: The χ (2) test revealed that the diagnosis of MS and the presence of elevated triglycerides increased with the overall POP-Q stage. The other MS risk factors were not significantly associated with the overall POP-Q stage. MS and elevated triglycerides were predictors of the POP-Q stage ≥III [odds ratio (OR) 3.5, 95 % confidence interval (CI) 1.5-8.2 for MS and OR 3.4, 95 % CI 1.4-8.2 for elevated triglycerides, p < 0.01]. CONCLUSIONS: The diagnosis of MS and the presence of elevated triglycerides may be associated with the severity of POP in urogynecological patients. Longitudinal studies are required to assess whether the MS risk factors might predict the progression of POP and whether elimination of the risk factors might improve the prognosis in POP patients.

Association of dopamine receptor gene polymorphisms with the clinical course of Wilson disease.

BACKGROUND: Dopamine receptor D2 (DRD2) polymorphisms are proposed to be important factors in the presentation of neuropsychiatric symptoms in many disorders, including decreased striatum levels of dopamine D2 receptors in Wilson disease. The present study investigated the association between DRD2 gene polymorphisms and clinical manifestation of Wilson disease. METHODS: Analyzing data from 97 symptomatic Wilson disease patients, we investigated the DRD2 gene polymorphisms rs1800497, rs1799732, and rs12364283. We assessed the polymorphisms impact on the phenotypic presentation of the disease. RESULTS: Generally, the DRD2 gene polymorphisms had no impact on the hepatic or neuropsychiatric clinical presentation of Wilson disease. However, rs1799732 deletion allele carriers with neuropsychiatric symptoms had earlier onset of WD symptoms by almost 6 years compared with individuals without this allele (22.5 vs. 28.3 years; P < 0.05). This unfavorable effect of the rs1799732 polymorphism was even more pronounced among adenosine triphosphatase 7B gene (ATP7B) p.H1069Q homozygous patients, in whom carriership of the deletion allele was related to earlier initial neuropsychiatric manifestation by 14 years (18.4 vs. 32.2 years; P < 0.01). CONCLUSIONS: Genetic variation of DRD2, specifically the rs1799732 polymorphism, may produce an earlier clinical presentation of Wilson disease neuropsychiatric symptoms and signs that occur in the course of dopaminergic system impairment due to copper accumulation in the brain. We speculate that this effect may be due to the impact of DRD2 polymorphism on dopamine D2 receptor density, but further studies are needed to understand the mechanisms of such phenotypic effects.

Family-based and case-control study of glutamate receptor GRIK3 Ser310Ala polymorphism in alcohol dependence.

AIM: The aim of this study was to evaluate the role of the glutamate receptor subunit-7 (GluR7, GRIK 3) rs6691840 (Ser310Ala, T928G) in the pathogenesis of alcohol dependence (AD). METHODS: DNA was provided from AD patients (n = 209) and healthy control subjects (n = 308) all of Polish descent. The history of alcoholism was obtained using the Polish version of the SSAGA (Semi-Structured Assessment for the Genetics of Alcoholism). We conducted case-control association study and transmission disequilibrium test (TDT). GRIK3 functional polymorphism was genotyped by the PCR-RFLP method. RESULTS: Analyses revealed that polymorphism Ser310Ala of GRIK3 gene is not associated with AD or any of its subgroups. TDT reveled an adequate transmission of both alleles in the group of alcohol families. CONCLUSIONS: These findings replicate and extend our previous research results that do not support the hypothesis of the role of rs6691840 in the pathogenesis of AD.

Increased ethanol intake and preference in cyclin D2 knockout mice.

Inhibitory effects of passive ethanol exposure on brain neurogenesis have been extensively documented in animal models. In contrast, a role of brain neurogenesis in ethanol self-administration has not been addressed, as yet. The aim of this study was to assess intake of, and preference for, ethanol solutions [2-16% (v/v)] in a mouse model of adult neurogenesis deficiency based on permanent knockout (KO) of cyclin D2 (Ccnd2). Wild type (WT) and Ccnd2 KO mice did not differ in 2% and 4% ethanol intake. The KO group consumed significantly more ethanol in g/kg when offered with 8% or 16% ethanol as compared with the WT controls. The WT and KO mice did not differ in 2% ethanol preference, but the KO group showed a significantly higher preference for 4-16% ethanol. Animal and human studies have suggested that the low level of response to the sedative/hypnotic effects of alcohol is genetically associated with enhanced alcohol consumption. However, in this study, there were no between-genotype differences in ethanol-induced loss of righting reflex. Previous reports have also suggested that high ethanol intake is genetically associated with the avidity for sweets and better acceptance of bitter solutions. However, the KO and WT mice consumed similar amounts of saccharin solutions and the KOs consumed less quinine (i.e. bitter) solutions as compared with the WTs. In conclusion, these results may indicate that Ccnd2 and, possibly, brain neurogenesis are involved in central regulation of ethanol intake in mice.

Gamma-aminobutyric acid concentrations in benign parotid tumours and unstimulated parotid saliva.

OBJECTIVE: Apart from its role as an inhibitory neurotransmitter, γ-aminobutyric acid is also thought to regulate various stages of cell proliferation and differentiation in the brain and periphery. The present study aimed to assess the levels of γ-aminobutyric acid and its biochemical precursor glutamic acid (glutamate) in benign parotid tumours and in unstimulated parotid saliva. METHOD: Unstimulated parotid saliva was collected bilaterally, using the swab method, in 20 patients with unilateral pleomorphic adenoma or Warthin's tumour. Samples of tumour and adjacent salivary tissue were collected during tumour resection. RESULTS: Concentrations of γ-aminobutyric acid and glutamate, but not aspartate, were significantly higher in the tumour tissue than in the non-tumour tissue. There was no significant difference in salivary concentrations of γ-aminobutyric acid, glutamate or aspartate, comparing the involved and non-involved side. CONCLUSION: The present results provide preliminary evidence that γ-aminobutyric acid may be involved in the growth of benign parotid tumours.

Genetic analysis of the mu-opioid receptor in alcohol-dependent individuals.

On the basis of various study results, it is suggested that the ethanol-induced activation of the endogenous opioid system may play an important role in mediating the reinforcing effects of ethanol. The mesolimbic dopamine reward system is activated by both ethanol and opioids, and genetic differences in the sensitivity of the endogenous opioid system to alcohol may be an important factor determining the risk for the development of excessive alcohol consumption. Thus, variants of the mu-opioid receptor (muOR) gene may confer vulnerability to alcohol dependence. Five exon 1 variants of the muOR were investigated in 327 alcohol-dependent and 340 healthy control subjects. The Val6 variant of the +17C/T polymorphism and the Asp40 variant of the +118A/G polymorphism showed a trend to an increased allele frequency in alcohol-dependent subjects. The latter polymorphism was investigated in more detail. The dopamine receptor agonist apomorphine causes an increase in growth hormone (GH) levels in the blood by stimulating the release of growth hormone-releasing hormone. beta-endorphin also activates this regulatory circuit. We found a blunted response in intoxicated alcohol-dependent subjects, but no difference in GH response between the groups of alcohol-dependent subjects with and without the variant Asp allele. However, alcohol-dependent subjects with the Asp allele showed a significantly higher GH response at day 7 after alcohol withdrawal and a tendency to lower novelty seeking. These results suggest to us that there is reduced dopaminergic neuronal activity in alcohol-dependent subjects with the muOR Asp40 allele, along with a compensating increase in dopamine receptor activity. The difference between the two groups of alcohol-dependent subjects can be demonstrated only under certain conditions such as alcohol withdrawal, which necessitates the adaptation of the neurones to a new homeostasis.

Polymorphisms in the dopamine, serotonin, and norepinephrine transporter genes and their relationship to temperamental dimensions measured by the Temperament and Character Inventory in healthy volunteers.

There is evidence for an association between polymorphisms of monoamine transporter genes and temperamental personality traits. Recent findings have shown that interaction of allelic variants of the different genes may contribute to the personality factors. We studied the association between temperamental personality dimensions measured with the Temperament and Character Inventory (TCI) and polymorphisms of the dopamine (DAT), norepinephrine (NET) and serotonin (5-HTT) transporter genes in 127 healthy Polish volunteers. There were no significant differences between means of TCI temperamental dimensions (novelty seeking, reward dependence, persistence and harm avoidance) and the transporter genes compared by ANOVA. There were some significant associations between genotypes and TCI subdimensions. Individuals carrying the A9/A9 DAT genotype have lower RD4 scores (dependence vs. independence) than A10/A10 individuals (3.0 +/- 1.4 vs. 3.5 +/- 1.3); p = 0.01. Examining 5-HTT gene promoter polymorphism, heterozygous individuals (l/s) and individuals with 44-bp deletion (s/s) scored significantly lower in the HA1 subdimension (anticipatory worry and pessimism vs. uninhibited optimism; 4.3 +/- 2.3 vs. 5.5 +/- 2.6) in comparison with individuals without deletion (l/l); p = 0.021. The NET transporter gene polymorphism showed no significant association with any of the temperamental TCI subdimensions.

[New implications for mental disorders treatment: pharmacogenetic studies of dopaminergic and serotonergic neurotransmission systems]. / Nowe perspektywy w leczeniu chorób psychicznych--badania farmakogenetyczne ukladów neuroprzekaznictwa dopaminergicznego i serotoninergicznego.

The aim of this article is to summarize the present state of pharmacogenetical knowledge compiled and based on various publications in this matter. Thanks to developing cloning and DNA-analysis techniques it is possible to analyze numerous proteins synthetized in the central nervous system. Several polymorphism sites in coding genes have already been located--first of all for some genes coding receptors linked to protein G, especially for dopamine and serotonine receptors. Some of mutations may influence the primary structure of receptor protein and in that way be responsible for alteration of receptors functioning. This is likely to be the reason for the difference in reaction to drugs in many patients. A couple of trials dealing with patient's response to neuroleptics in correlation with receptor genes polymorphism have already been completed. The results are promising. The assumption that inventing new drugs should be correlated with collecting DNA samples from patients to evaluate further pharmacogenetical linkage seems to be essential.

Different allele distribution of a regulatory MAOA gene promoter polymorphism in antisocial and anxious-depressive alcoholics.

Heritable factors account for approximately 40-60% of the total variance of liability to alcohol dependence. The present study tested whether a novel functional polymorphism in the promotor region of the X-chromosomal monoamine oxidase A gene (MAOA) was related to antisocial and anxious-depressive traits in alcoholics. Due to the X-chromosomal localization of the MAOA gene, psychobiological traits were compared separately for both genders of 298 male and 66 female alcoholics. In males, 30 of 59 alcoholics with antisocial personality disorder carried the low-activity 3-repeat allele in contrast to only 7 of 31 anxious-depressive alcoholics (51% vs. 23%; p = 0.02). Likewise, female anxious-depressive alcoholics showed a trend towards a low frequency of genotypes with the 3 repeat allele compared to female alcoholics without these symptoms (29% vs. 53%; p = 0.09). Taken together, these findings suggest that the 3-repeat allele of the MAOA polymorphism contributes modestly to the dimension of overand underreactive behaviors as possible antecedents of alcoholism.

Variation of the genes encoding the human glutamate EAAT2, serotonin and dopamine transporters and Susceptibility to idiopathic generalized epilepsy.

Several interacting genetic factors are likely to be involved in the epileptogenesis of idiopathic generalized epilepsies (IGE). Neurotransmitter transporters play a central role in the fine tuning of neurotransmission by removal of released neurotransmitters from the synaptic cleft. The present association study tested the hypotheses that variation of the genes encoding neurotransmitter transporters confers susceptibility to IGE. The genotypes of 133 German IGE subjects and 223 ethnically matched controls were assessed for DNA polymorphisms of genes encoding the glutamate (EAAT2), the serotonin (SERT), and dopamine (DAT) transporters. To increase genetic homogeneity, a subgroup of 76 patients with idiopathic absence epilepsy (IAE) was analyzed separately. We found no evidence for an allelic association of either the silent G603A substitution polymorphism in exon 5 of the EAAT2 gene or the regulatory promoter polymorphism of the SERT gene with either IGE or IAE. The frequency of the nine-copy allele of the 40 base pair repeat polymorphism in the 3' un pop popd region of the DAT gene was significantly increased in the IGE patients (chi2 = 4.11, degrees of freedom (d.f.) = 1, P = 0.043) and, in particular, in the IAE patients (chi2 = 7.81, d.f. = 1, P = 0.005) compared with the controls. The present findings strengthen previous evidence that genetic variation of the DAT gene modulates neuronal network excitability and contributes to the epileptogenesis of IAE.

Five exon 1 variants of mu opioid receptor and vulnerability to alcohol dependence.

The human mu opioid receptor (hMOR) gene is a prime candidate gene responsible for addictive disorders. The present association study tested the hypothesis that hMOR exon 1 variants elicit susceptibility to alcohol dependence. We have analyzed five nucleotide changes in exon 1 of the hMOR gene. Three of them are in the 5'untranslated region of exon 1 at positions -172G/T,-111C/T and -3 8C/A, the remaining two variants cause amino acid substitutions: +17C/T (Ala6Val) and +118A/G (Asn40Asp). Our population-based association study included 327 German alcohol-dependent subjects and 340 ethnically matched controls. The lack of an allelic association suggests that the analyzed hMOR exon 1 variants do not contribute a common and substantial effect to the genetically determined vulnerability of alcohol dependence.

[The influence of genes on the development of personality]. / Wplyw genów na ksztaltowanie sie cech osobowosci.

Antisocial behavior and personality disorders are both heterogeneous and the product of interacting genetic and environmental factors acting at different levels of causation. Heritability studies show that individual differences in predisposition to antisocial behavior are transmitted by genetic mechanisms in families. Direct gene analysis and genetic linkage analysis have identified structural variants in genes involved in neurotransmitter function, and some progress has been made towards relating these genetic variants to antisocial personality and other behaviors. The monoamine oxidase-A variant leads to aggressive behavior in one family. Direct gene analyses have revealed amino acid substitutions and structural variants at DRD2, DRD3 and DRD4 dopamine receptors and 5-HT2A, 5-HT2C serotonin receptors, serotonin transporter gene, and genes for enzymes, metabolizing biogenic amines MAO-A, MAO-B. The stage is set to identify the phenotypic significance of these as well as genetic variants at other loci which may be relevant as candidate genes for antisocial behavior and related behavioral differences.

Evaluation of an allelic association of the serotonin 5-HT1B G681C polymorphism with antisocial alcoholism in the German population.

Our study tested whether an association of the 861C allele of the serotonin 5-HT1B gene (HTR1B) with antisocial alcoholism exists in the German population. The HTR1B G861C polymorphism was genotyped in 588 subjects of German descent, comprising 250 non-alcoholic controls and 338 alcohol-dependent subjects, of whom 56 exhibited a dissocial personality disorder (DSPD). The Tridimensional Personality Questionnaire was assessed in 109 alcohol-dependent males to explore an effect of the 861C allele to risk-taking behaviour. Our results revealed no evidence for an association of the 861C allele with antisocial alcoholism (p > 0.63). There were no significant differences in the personality traits, novelty-seeking, harm avoidance and reward dependence between 46 male alcoholics carrying the 861C allele compared to those 63 alcoholics lacking it (p > 0.52). Our results do not provide evidence that the 861C allele contributes a substantial vulnerability effect to antisocial behavior in German alcohol-dependent subjects.
