Proof of Concept of the Electrochemical Sensing of 3-Iodothyronamine (T1AM) and Thyronamine (T0AM)

Recent studies have shown that, besides the well-recognized T3 and T4 hormones, there are other relevant thyroid hormones circulating in the human body. In particular, this is the case for 3-iodothyronamine (T1AM) and thyronamine (T0AM). One of the reasons for the lack of studies showing their precise importance is the absence of analytical methodologies available. Herein, for the first time, T1AM and T0AM are electrochemically characterized. T0AM was sensed by means of a glassy carbon electrode; furthermore, T1AM was sensed both with a graphitic surface (oxidatively) as well as with mercury (reductively). For both compounds, after oxidation, it was possible to observe the reversible redox reaction concerning the benzoquinone/hydroquinone couple, thus increasing the specificity of the electroanalysis. Therefore, this work provides the basis for an ‘at-point-of-use’ electrochemical strip test for T1AM and T0AM.

Equidade na utilização de medicamentos em Portugal

RESUMO - Este estudo teve como objectivo contribuir para o conhecimento sobre a equidade no sector do medicamento, com uma análise empírica aplicada ao sistema de saúde português. Para o efeito avaliou-se se indivíduos com as mesmas necessidades em saúde, mas com diferentes níveis de rendimento, tiveram idêntica prestação no que diz respeito ao medicamento. Adicionalmente, aprofundou-se esta análise através da identificação de factores associados ao sistema de prestação ou ao utente que contribuíram para gerar iniquidades, com particular destaque para os comportamentos de não aquisição de medicamentos – não adesão primária. A avaliação da equidade foi efectuada através de duas abordagens distintas, mas complementares: uma sob a perspectiva da utilização e outra sob a perspectiva da distribuição da despesa pública com medicamentos. Para estas análises aplicaram-se métodos baseados nos índices de concentração, utilizando dados do Inquérito Nacional de Saúde 2005/06 e dados relativos aos encargos do Serviço Nacional de Saúde com medicamentos. Os resultados revelaram que, perante as mesmas necessidades, o sistema de prestação tende a favorecer os indivíduos de nível socioeconómico superior, quer na utilização quer na distribuição de recursos do Estado com medicamentos. Adicionalmente, a aplicação do método da decomposição do índice de concentração revelou que tanto o rendimento como o nível educacional são atributos individuais que estão associados à iniquidade na utilização de medicamentos. A iniquidade observada neste estudo pode resultar de barreiras em diferentes fases do processo terapêutico, entre as quais se destacam o não acesso à prescrição médica ou a não aquisição dos medicamentos prescritos. Foi este comportamento - designado de não adesão primária - que se analisou na segunda parte da tese. Para tal cruzaram-se os dados de prescrição electrónica com os dados de dispensa no Serviço Nacional de Saúde. Os resultados revelaram que a taxa de não adesão primária foi cerca de 20% e que este comportamento está associado ao sexo feminino ou ser jovem, assim como a características do sistema de prestação como o valor dos copagamentos. Estes dados indiciam que as barreiras na aquisição podem ser indutoras de iniquidades na utilização de medicamentos. A identificação de iniquidade na utilização de medicamentos e dos factores que contribuem para esta situação constituem o primeiro passo para uma estratégia de redução da iniquidade que, de acordo com os resultados desta tese, deve abranger não só o sistema de saúde mas também outras áreas das políticas públicas em Portugal.

A Brazilian version of the "Children's Interview for Psychiatric Syndromes" (ChIPS)

OBJETIVE: The advance of research in child and adolescent psychiatry in Brazil heavily depends on the existence of instruments for the investigation of psychiatric syndromes adapted to Brazilian Portuguese. METHODS: This article describes a careful process of translation of the Children's Interview for Psychiatric Syndromes for the purpose of use in research in Brazil. The Children's Interview for Psychiatric Syndromes has a version for parents (P-ChIPs) and a version for children (ChIPS). In this article, the sections of P-ChIPS referring to attention-deficit hyperactivity disorder, oppositional-defiant disorder, conduct disorder, mania/hypomania, anorexia nervosa, bulimia nervosa and psychotic disorders were translated to Brazilian Portuguese. The sections of the ChIPS referring to substance use disorders, social anxiety disorder, specific phobias, obsessive-compulsive disorder, generalized anxiety disoder, separation anxiety disorder, post-traumatic disorders and depression/dysthimia were also adapted. Each section was translated by two independent translators and later discussed in a committee composed of experts in the field of Psychiatry and a professional of the field of linguistics. RESULT: A final version containing an interview for the main psychiatric syndromes was defined. CONCLUSION: The translated P-ChIPS is a helpful instrument in children and adolescent clinical evaluation.

Prévention des alcoolisations aiguës a l'adolescence: quel rôle pour le médecin de famille [Prevention of binge drinking in adolescents: do family doctors have a role to play?].

Binge drinking has nearly become the norm for young people and is thus worrying. Although alcohol use in males attracts more media attention, females are also frequently affected. A variety of preventive measures can be proposed: at the individual level by parents, peers and family doctors; at the school and community level, particularly to postpone age of first use and first episode of drunkenness; at the structural level through a policy restricting access to alcohol for young people and increasing its price. Family doctors can play an important role in identifying at risk users and individualising preventive messages to which these young people are exposed in other contexts.

Social contexts of sports-practicing youths' hazardous drinking.

Sports-practicing youths are at an elevated risk for alcohol use and misuse. Although much attention has recently been given to depicting subgroups facing the greatest threats, little evidence exists on the contexts in which their drinking takes place. Using data from a cross-sectional study on youth sports participation and substance use in the French-speaking part of Switzerland, this study focused on the social contexts associated with hazardous drinking of 894 sports-practicing adolescents aged 16 to 20. Divided between those who had been drunk in the last month (hazardous drinkers, n = 315) and those who had not (n = 579), sports-practicing adolescents were compared on reported gatherings (sports-related, sports-unrelated, mixed) likely linked to their drinking behaviour. Mixed social contexts, followed by sports-unrelated ones, were reported as the most common context by both male and female youths who practiced sports. After controlling for several possible confounders, male hazardous drinkers were more than 3 times more likely to report sports-unrelated social contexts as the most common, compared to sport-related ones, while females were more than 7 times more likely to do so. Our findings seem to indicate that, rather than focusing only on sports-related factors, prevention of alcohol misuse among sports-practicing youths should also pay attention to the social contextualisation of their hazardous drinking.

No healthy heart for heavy drinkers: a population-based study in Switzerland

Background: Low to moderate alcohol consumption has been associated with lower coronary heart disease (CHD) risk, an effect mainly mediated by an increase in HDL-cholesterol levels. However, data on the CHD risk associated with high alcohol consumption are conflicting. Methods: In a population-based study of 5,769 men and women, aged 35-75 years, without cardiovascular disease in Switzerland, last week alcohol consumption was categorized into 0, 1-6, 7-13, 14-20, 21-27, 28-34, 035 drinks/week and into nondrinkers (0 drink/week), moderate (1-13), high (14-34) and very high drinkers (035). Blood pressure, lipids and high sensitivity C-reactive protein (hs-CRP) were measured, and the 10-year CHD risk was calculated according to the Framingham risk score. Results: 73% (n = 4,214) of the participants consumed alcohol; 16% (n = 909) were considered as high drinkers and 2% (n = 119) as very high drinkers. In multivariate analysis, increasing alcohol consumption was associated with higher HDL-cholesterol (from 1.57 ± 0.01 [adjusted mean ± SE] in nondrinkers to 1.88 ± 0.03 mmol/L in very high drinkers); triglycerides (1.17 ± 1.01 to 1.32 ± 1.05 mmol/L), and systolic and diastolic blood pressure rose significantly (127.4 ± 0.4 to 132.2 ± 1.4 and 78.7 ± 0.3 to 81.7 ± 0.9 mm Hg, respectively, all p for trend <0.001). Predicted 10-year CHD risk increased from 4.31 ± 0.10 to 4.90 ± 0.37 (p = 0.03) with increasing alcohol use, with a J-shaped relationship. Conclusion: As measured by the 10-year CHD risk, the protective effect of alcohol consumption disappears in very high drinkers, namely because the beneficial increase in HDL-cholesterol may be blunt by a rise in blood pressure levels.

Coronary magnetic resonance angiography.

Despite advances in both prevention and treatment, cardiovascular disease remains the leading cause of morbidity and mortality in the United States. The current gold standard for the diagnosis of coronary artery disease is the x-ray coronary angiogram, which is both costly and associated with a small risk of morbidity. More than 1 million Americans are referred for this test annually, and despite the availability of numerous noninvasive tests to identify patients with coronary artery disease, > or =35% of patients referred for this test are found not to have disease. It therefore would be beneficial to use a noninvasive test to allow the presence of coronary atherosclerosis to be determined directly. Coronary magnetic resonance angiography, a technique that is aimed at establishing a noninvasive test for the assessment of significant coronary stenoses, obviates the risks of patient exposure to radiation of x-ray angiography and therefore represents a major step forward in diagnostic cardiology.

Binge drinking in 19 year old men.

QUESTION UNDER STUDY: To describe alcohol use, binge drinking and drinking consequences in 19 year old men. METHODS: During a one-day army recruitment process mandatory for all Swiss males, a convenience sample of 1,004 men completed the "Health and Lifestyle Questionnaire", assessing demographics, alcohol use, binge drinking, and drinking consequences over the last 12 months. Binge drinking was defined as having 5 or more drinks on a single occasion at least once over the last 12 months. Among the 1,004 subjects, binge drinking could not be defined in 123 (12.3%) due to "don't know" responses, leaving 881 subjects with complete data. RESULTS: Of the 881 subjects, 690 (78.3%) reported binge drinking at least once over the last 12 months, 269 (30.5%) with infrequent binge drinking (< or = 1x/month) and 421 (47.8%) with frequent binge drinking (> or = 2x/month). In addition, 379 (43.0%) of the subjects experienced 3 or more drinking consequences over the last 12 months and the number of these consequences increased as the frequency of binge drinking increased (trend analyses significant for 9 of the 12 consequences evaluated). Among the 687 subjects with moderate average alcohol intake (< 14 drinks per week), 252 (36.7%) reported infrequent binge drinking, of whom 82 (32.5%) experienced 3 or more adverse drinking consequences over the last 12 months, whereas 246 (35.8%) reported frequent binge drinking and 128 (52.0%) of these experienced 3 or more adverse drinking consequences. CONCLUSIONS: Binge drinking in this sample of young men is frequent and is associated with numerous consequences, even among those consuming moderate amounts of alcohol.

A Survey of Employees Attitudes Towards Drug Testing in the Workplace

In light of the recent publication of the safety, Health & Welfare at Work Bill 2004, which is set to target the construction industry in particular, the number of Irish employers implementing drug testing programmes in the workplace is set to increase. Little is known, however, about attitudes of Irish workers towards various aspects of drug testing. In order to address this matter, the author presents the findings of a cross-sectional survey of 148 construction trade apprentices in relation to their attitudes towards aspects of workplace drug testing. The extent to which their attitudes varied according to their levels of illegal drug use and alcohol use was also investigated. The results indicate that under some circumstances, testing is approved of. However, attitudes towards most aspects of drug testing are characterised by extreme variability. For example, nearly items were rejected by some respondents and accepted by others. It can be concluded that even if an employer designed a drug testing programme based on elements viewed more favourably, a substantial proportion of employees would still be likely to hold negative views towards some aspects of the programme. Furthermore, self-reported frequency of alcohol and drug use, particularly cannabis use, was associated to more negative reactions towards drug testing. Implications for implementing drug testing programmes in the workplace are discussed. The results of this study are intended to give employers an increased understanding of workers' attitudes towards drug testing programmes and to aid the development of effective substance-abuse prevention services.This resource was contributed by The National Documentation Centre on Drug Use.

Dublin Simon Community health audit. The complexities of homelessness.

The Dublin Simon Community Health Audit took place during a one week period from Tuesday October 27th to Monday November 2nd 2009. During this one week period the survey was conducted with representative sample of people using Dublin Simon services to provide a snapshot picture of the presenting needs and issues Dublin Simon Community work with on a daily basis. The information gathered builds up a picture of the complex nature of both homelessness and the physical/mental health needs of those experiencing homelessness. Specifically it looks at the physical health issues, diagnosed and undiagnosed; mental health issues, diagnosed and undiagnosed; and drug and alcohol use of those using Dublin Simon services over this one week period.This resource was contributed by The National Documentation Centre on Drug Use.

Influence of counselor characteristics and behaviors on the efficacy of a brief motivational intervention for heavy drinking in young men-a randomized controlled trial.

BACKGROUND: Brief motivational intervention (BMI) has shown promising results to reduce alcohol use in young adults. Knowledge on mechanisms that predict BMI efficacy could potentially improve treatment effect sizes through data that optimize clinical training and implementation. Particularly, little attention has been given to counselor influence on treatment mechanisms. METHODS: We investigated the influence of counselors on BMI efficacy in reducing alcohol use among non-treatment-seeking young men (age 20) screened as hazardous drinkers. Participants were randomly allocated to (i) a group receiving a single BMI from 1 of 18 counselors selected to maximize differences in several of their characteristics (gender, professional status, clinical experience, and motivational interviewing [MI] experience) or (ii) a control group receiving assessment only. Drinking at 3-month follow-up was first compared between the BMI and control groups to assess efficacy. Then, the influence of counselors' characteristics (i.e., gender, professional status, clinical experience, MI experience, BMI attitudes, and expectancies) and within-session behaviors (i.e., measured by the Motivational Interviewing Skill Code) on outcome was tested in regression analyses. RESULTS: There was a significant (p = 0.02) decrease in alcohol use among the BMI group compared to the control group. Counselors that were male, more experienced, that had more favorable BMI attitudes and expectancies, higher MI skills, but surprisingly less MI-consistent behaviors, had significantly better outcomes than the control group while their counterparts did not. CONCLUSIONS: The current study demonstrated BMI efficacy on alcohol use reduction within a sample of non-treatment-seeking young adult males. Moreover, BMI effect was related to interindividual differences among counselors, and results therefore provide recommendations for BMI training and implementation with similar populations.

Mental Health First Aid Training Programme

The Mental Health First Aid (MHFA) Training Programme for Northern Ireland has been adapted from the original MHFA programme established in Australia by Betty Kitchener and Anthony Jorm. MHFA is the help provided to a person who is developing a mental health problem or who is currently in a mental health crisis. The first aid is given until professional help is available or until the crisis resolves. More than 4,500 people have attended MHFA training in Northern Ireland since it began in 2009 following a successful pilot in 2005. The aims of MHFA are to: preserve life where a person may be a danger to themselves or others; provide help to prevent the mental health problem becoming more serious; promote the recovery of good mental health; provide comfort to a person experiencing a mental health problem. MHFA teaches participants: how to recognise the symptoms of mental health problems; how to provide initial help; how to go about guiding a person towards appropriate professional help. The training programme is available to people from all backgrounds and has proved successful with different professional groups. MHFA training involves teaching participants how to recognise the symptoms of mental health problems such as depression, anxiety and psychosis. Each course is delivered by two MHFA instructors, usually over two consecutive days and four sessions to a maximum of 20 delegates. The course can also be delivered one day a week for two weeks or in four three-hour sessions. To apply for the training programme, people should contact their local Health and Social care Trust. Each Trust runs MHFA training several times a year. Topics covered include: What is meant by mental health/mental ill health? Dealing with crisis situations such as suicidal behaviour, self-harm, panic attacks and acute psychotic behaviour. Recognising the signs and symptoms of common mental health problems including depression, anxiety disorders, psychosis and substance use disorders. Where and how to get help. Self help strategies.
