The size and burden of mental disorders and other disorders of the brain in Europe 2010.

Aims: To provide 12-month prevalence and disability burden estimates of a broad range of mental and neurological disorders in the European Union (EU) and to compare these findings to previous estimates. Referring to our previous 2005 review, improved up-to-date data for the enlarged EU on a broader range of disorders than previously covered are needed for basic, clinical and public health research and policy decisions and to inform about the estimated number of persons affected in the EU. Method: Stepwise multi-method approach, consisting of systematic literature reviews, reanalyses of existing data sets, national surveys and expert consultations. Studies and data from all member states of the European Union (EU-27) plus Switzerland, Iceland and Norway were included. Supplementary information about neurological disorders is provided, although methodological constraints prohibited the derivation of overall prevalence estimates for mental and neurological disorders. Disease burden was measured by disability adjusted life years (DALY). Results: Prevalence: It is estimated that each year 38.2% of the EU population suffers from a mental disorder. Adjusted for age and comorbidity, this corresponds to 164.8 million persons affected. Compared to 2005 (27.4%) this higher estimate is entirely due to the inclusion of 14 new disorders also covering childhood/adolescence as well as the elderly. The estimated higher number of persons affected (2011: 165 m vs. 2005: 82 m) is due to coverage of childhood and old age populations, new disorders and of new EU membership states. The most frequent disorders are anxiety disorders (14.0%), insomnia (7.0%), major depression (6.9%), somatoform (6.3%), alcohol and drug dependence (>4%), ADHD (5%) in the young, and dementia (1-30%, depending on age). Except for substance use disorders and mental retardation, there were no substantial cultural or country variations. Although many sources, including national health insurance programs, reveal increases in sick leave, early retirement and treatment rates due to mental disorders, rates in the community have not increased with a few exceptions (i.e. dementia). There were also no consistent indications of improvements with regard to low treatment rates, delayed treatment provision and grossly inadequate treatment. Disability: Disorders of the brain and mental disorders in particular, contribute 26.6% of the total all cause burden, thus a greater proportion as compared to other regions of the world. The rank order of the most disabling diseases differs markedly by gender and age group; overall, the four most disabling single conditions were: depression, dementias, alcohol use disorders and stroke. Conclusion: In every year over a third of the total EU population suffers from mental disorders. The true size of "disorders of the brain" including neurological disorders is even considerably larger. Disorders of the brain are the largest contributor to the all cause morbidity burden as measured by DALY in the EU. No indications for increasing overall rates of mental disorders were found nor of improved care and treatment since 2005; less than one third of all cases receive any treatment, suggesting a considerable level of unmet needs. We conclude that the true size and burden of disorders of the brain in the EU was significantly underestimated in the past.Concerted priority action is needed at all levels, including substantially increased funding for basic, clinical and public health research in order to identify better strategies for improved prevention and treatment for isorders of the brain as the core health challenge of the 21st century.

Résistances thérapeutiques dans les mouvements anormaux [Resistance to treatment in movement disorders].

Therapeutic strategies for essential tremor (ET) and Parkinson's disease (PD) can be divided into two successive steps, one based on oral medications and the other, more invasive, using pumps or functional neurosurgery. When ET becomes refractory to propranolol, primidone and other, second-choice compounds, deep brain stimulation of the VIM nucleus of the thalamus can be considered. When PD becomes resistant to dopamine replacement therapy using various combinations of dopaminergic agents, then three options can be discussed: first, a subcutaneous apomorphine mini-pump, second, a jejunal levodopa-delivery system by means of percutaneous gastrostomy, and third, bilateral deep brain stimulation of the subthalamic nucleus. The above interventions are successful in about 80% of cases.

Les troubles psychiatriques des patients âgés avec une maladie de Parkinson et leurs traitements [Psychiatric disorders in elderly patients with Parkinson's disease and their treatments].

Parkinson's disease (PD) is a neuropsychiatric disorder. During the course of PD, most patients develop at least one psychiatric syndrome. Depression is the most frequent disorder and affects nearly half of all patients. The use of an increasing number of new drugs, in particular the dopaminergic agents, puts these patients at risk of developing both delirium and psychosis. This article summarizes the different psychiatric syndromes seen in PD and gives an account of the various treatment possibilities.

Co-infecção por vírus da hepatite B e vírus da imunodeficiência humana em países africanos

Introdução: Actualmente, estima-se que existam dois milhões de indivíduos infectados por vírus da hepatite B (VHB) e que, cerca de 25% dos indivíduos com infecção crónica morrem devido a sequelas resultantes da infecção por VHB. Paralelamente, calcula-se que existam cerca de 33 milhões de indivíduos infectados por VIH, sendo que 22, 5 milhões residem na região de África a sul do Sara. Na região de África a sul do Sara existem poucos estudos efectuados no âmbito da co-infecção por VIH/VHB. Contudo, dos estudos existentes, esta taxa pode situar-se entre os 2,4% e os 9,9%. Objectivo: Avaliar as taxas de seroprevalência de VHB e VIH, assim como a taxa de co-infecção por VIH/VHB em Angola, Cabo Verde, Guiné-Bissau e Moçambique. Métodos: Foram efectuadas duas pesquisas bibliográficas neste estudo. A primeira, realizada nos meses de Setembro/Outubro 2008, tinha como objectivo contextualizar a infecção por VHB, VIH e a co-infecção por VIH/VHB nos países desenvolvidos e nos países em desenvolvimento. A segunda pesquisa foi efectuada durante o mês de Agosto de 2009, e visava apenas cobrir a realidade dos países em análise, relativamente aos objectivos previamente delineados do estudo. Resultados: Em Moçambique, constatou-se que a seroprevalência de VIH-1 tinha quadriplicado entre 1993 (1,17%) e o ano 2000 (4,5%). Na Guiné-Bissau, entre 1997 e 1999, também a seroprevalência de VIH-1 duplicou (2,5% e 5,2%, respectivamente). Em Cabo-Verde, no ano de 2006, a seroprevalência de VIH era 2,4%, enquanto que a seroprevalência da infecção por VHB era 4,4%. Em Angola, no ano de 2005, a seroprevalência de VIH era de 2,5%. Neste estudo também foi avaliada a co-infecção, sendo que nenhum caso foi diagnosticado. Conclusão: É urgente realizarem-se mais estudos nos países PALOP, no âmbito da seroprevalência das monoinfecções VIH e VHB, assim como na co-infecção por VIH/VHB, uma vez que existe pouca informação disponível. De qualquer modo, sendo a infecção por VHB uma doença prevenível por vacina, é fundamental que os planos de vacinação continuem a ser postos em prática nos países onde já estão implementados e, no caso dos países que ainda não os têm, que a sua implementação seja efectuada de forma sustentada e o mais brevemente possível.

A leverage theory of reputation building with co-branding: Complementarity in reputation building

We present a leverage theory of reputation building with co-branding. We showthat under certain conditions, co-branding that links unknown firms in a new sectorwith established firms in a mature sector allows the unknown firms to signal a highproduct quality and establish their own reputation. We compare this situationwith a benchmark in which both sectors are new and firms signal their qualityonly with prices. We investigate how this comparison is affected by the nature ofthe technology linking the two sectors and a cross-sector inference problem thatconsumers might face in identifying the true cause of product failure. We find thatco-branding facilitates the process in which a Þrm in the new sector to signal itsproduct quality only if the co-branding sectors produce complementary inputs andconsumers face a cross-sector inference problem. We apply our insight to economicsof superstars, multinational firms and co-authorship.

Identifying the gap between need and intervention for alcohol use disorders in Europe.

AIMS: A literature review of existing research on the prevalence of alcohol use disorders (AUDs) and availability of alcohol interventions in Europe was conducted. The review also explored what is known about the gap between need and provision of alcohol interventions in Europe. METHODS: The review search strategy included: (i) descriptive studies of alcohol intervention systems in Europe; (ii) studies of alcohol service provision in Europe; and (iii) studies of prevalence of AUD and alcohol needs assessment in Europe. RESULTS: Europe has a relatively high level of alcohol consumption and the resulting disabilities are the highest in the world. Most research on implementation of alcohol interventions in Europe has been restricted to screening and brief interventions. Alcohol needs assessment methodology has been developed but has not been applied in comparative studies across countries in Europe. CONCLUSIONS: This review points to key gaps in knowledge related to alcohol interventions in Europe. There is a lack of comparative data on variations in alcohol treatment systems across European countries and there is also a lack of comparative data on the prevalence of alcohol use disorders across European countries and the relative gap between need and access to treatment. The forthcoming Alcohol Measures for Public Health Research Alliance (AMPHORA) research project work package on 'Early identification and treatment' aims to address these gaps.

Internet use by patients with psychiatric disorders in search for general and medical informations

BACKGROUND: Internet is commonly used by the general population, notably for health information-seeking. There has been little research into its use by patients treated for a psychiatric disorder. AIM: To evaluate the use of internet by patients with psychiatric disorders in searching for general and medical information. METHODS: In 2007, 319 patients followed in a university hospital psychiatric out-patient clinic, completed a 28-items self-administered questionnaire. RESULTS: Two hundred patients surveyed were internet users. Most of them (68.5%) used internet in order to find health-related information. Only a small part of the patients knew and used criteria reflecting the quality of contents of the websites consulted. Knowledge of English and private Internet access were the factors significantly associated with the search of information on health on Internet. CONCLUSIONS: Internet is currently used by patients treated for psychiatric disorders, especially for medical seeking information.

(Re)configuração identitária das mulheres cujos maridos/companheiros emigraram: Uma análise a partir das mulheres de Pilão-Cão

Esta dissertação visa investigar a realidade das mulheres cujos maridos/companheiros emigraram em Pilão Cão de modo a compreender se as mudanças ocorridas a partir da saída dos seus cônjuges as levam a construir uma nova imagem de si e por conseguinte uma nova identidade. Para a concretização desse objectivo realizou-se uma pesquisa etnográfica junto dessas mulheres onde foram recolhidos os dados que retractam vários aspectos relacionados às suas experiências pessoais e familiares, concretamente os papéis desempenhados, os sentimentos experimentados, o controle social a que são sujeitas e sua relação com os próprios familiares e com os familiares do marido/companheiro. A análise dos dados mostrou que as modificações às quais foram sujeitas são percebidas de uma forma diferente por essas mulheres, dependendo da relação que mantém com os seus maridos/companheiros no estrangeiro. Entretanto ficou patente que em alguns casos assumiram mudanças e a construção de uma nova identidade e noutros casos houve apenas a alteração dos papéis de género.

Predictors and Moderators of Clinical Outcomes in Adolescents with Severe Mental Disorders After an Assertive Community Treatment.

Previous studies have shown that stressful life events (SLEs), gender, social functioning and pretreatment severity are some of the predictors and/or moderators of treatment outcome in psychiatric care. The current study explored the effect of these predictors and moderators on the treatment outcome related to assertive community treatment (ACT) proposed to young people with severe mental disorders. 98 patients were assessed for externalizing and emotional difficulties, at admission and then at discharge of an ACT. Analyses revealed significant improvements in terms of symptomatology. In particular, regression analyses showed that pretreatment severity is a significant predictor of the outcome on emotional symptoms and is moderated by SLE on the outcome on externalizing symptoms. Furthermore, higher social functioning proved to predict better outcome on externalizing symptoms. Our results further evidence that these factors can explain inter-individual differences in outcome related to ACT. The theoretical and clinical implications of these results are discussed.

Current concepts in the pathogenesis of urea cycle disorders.

The common feature of urea cycle diseases (UCD) is a defect in ammonium elimination in liver, leading to hyperammonemia. This excess of circulating ammonium eventually reaches the central nervous system, where the main toxic effects of ammonium occur. These are reversible or irreversible, depending on the age of onset as well as the duration and the level of ammonium exposure. The brain is much more susceptible to the deleterious effects of ammonium during development than in adulthood, and surviving UCD patients may develop cortical and basal ganglia hypodensities, cortical atrophy, white matter atrophy or hypomyelination and ventricular dilatation. While for a long time, the mechanisms leading to these irreversible effects of ammonium exposure on the brain remained poorly understood, these last few years have brought new data showing in particular that ammonium exposure alters several amino acid pathways and neurotransmitter systems, cerebral energy, nitric oxide synthesis, axonal and dendritic growth, signal transduction pathways, as well as K(+) and water channels. All these effects of ammonium on CNS may eventually lead to energy deficit, oxidative stress and cell death. Recent work also proposed neuroprotective strategies, such as the use of NMDA receptor antagonists, nitric oxide inhibitors, creatine and acetyl-l-carnitine, to counteract the toxic effects of ammonium. Better understanding the pathophysiology of ammonium toxicity to the brain under UCD will allow the development of new strategies for neuroprotection.

Troubles du cycle à l'adolescence: une banalité [Menstrual disorders in adolescents: commonplace or worrisome?].

The first menstrual cycles following menarche are often caracterized by irregular and/or heavy bleeding. The adolescent patient may be worried by these episodes of bleeding. In 50-80% of cases these are anovulatory bleeding due to the immaturity of the gonadotrophic axis. Nevertheless pathologies such as von Willebrand disease, genital infection, polycystic ovary syndrom, eating disorders, a tumor or a pregnancy may be diagnosed by bleeding abnormalities. The challenge for the physician is to distinguish between bleeding abnormalities secondary to anovulation and pathologies where investigations and specific follow-up is mandatory. Adolescents who experience abnormal bleeding must be counceled according to their perceptions and expectations.

Systematic study of the static electrical properties of the CO molecule: influence of the basis set size and correlation energy

The influence of the basis set size and the correlation energy in the static electrical properties of the CO molecule is assessed. In particular, we have studied both the nuclear relaxation and the vibrational contributions to the static molecular electrical properties, the vibrational Stark effect (VSE) and the vibrational intensity effect (VIE). From a mathematical point of view, when a static and uniform electric field is applied to a molecule, the energy of this system can be expressed in terms of a double power series with respect to the bond length and to the field strength. From the power series expansion of the potential energy, field-dependent expressions for the equilibrium geometry, for the potential energy and for the force constant are obtained. The nuclear relaxation and vibrational contributions to the molecular electrical properties are analyzed in terms of the derivatives of the electronic molecular properties. In general, the results presented show that accurate inclusion of the correlation energy and large basis sets are needed to calculate the molecular electrical properties and their derivatives with respect to either nuclear displacements or/and field strength. With respect to experimental data, the calculated power series coefficients are overestimated by the SCF, CISD, and QCISD methods. On the contrary, perturbation methods (MP2 and MP4) tend to underestimate them. In average and using the 6-311 + G(3df) basis set and for the CO molecule, the nuclear relaxation and the vibrational contributions to the molecular electrical properties amount to 11.7%, 3.3%, and 69.7% of the purely electronic μ, α, and β values, respectively
