Methadone maintenance therapy for opioid dependence - A guide to appropriate use

Opioid dependence is a chronic, relapsing condition that is associated with significant morbidity and mortality. Methadone maintenance therapy involves the provision of a controlled supply of an orally administered opioid, thereby stabilising the opioid-dependent patient. Research studies have shown that methadone maintenance reduces illicit opioid use, opioid-related crime, premature mortality and the risk of HIV infection. It is most effective when prescribed at an adequate dosage (usually 60 to 100 mg/day) and when long term maintenance on methadone is the goal of treatment rather than detoxification from all drugs including methadone. Successful long term methadone maintenance is more likely when it takes place within the context of a well established therapeutic relationship and when the medical, social and psychological needs of patients are met either through direct assistance or referral.

Sudden unexpected death in an adolescent with epilepsy: All roads lead to the heart?

The incidence of sudden unexpected death in epilepsy (SUDEP) has been estimated from 0.5-1.4/1,000 person-years in people with treated epilepsy, and 9/1,000 person-years in candidates for epilepsy surgery. Potential risk factors for SUDEP include: age, early onset of epilepsy, duration of epilepsy, uncontrolled seizures, seizure type and winter temperatures. The arrythmogenic side-effect of antiepileptic drugs and seizures may increase the risk of SUDEP. In this report, we describe a patient with prolonged post-ictal tachycardia in EEG video recordings with a typical case of SUDEP: a 16-year-old boy with medically intractable complex partial seizures. Magnetic resonance imaging revealed left mesial temporal sclerosis. During non-invasive video-EEG monitoring, the patient presented a post-ictal heart rate increased for five hours. Two months after video-EEG, he died from SUDEP during a tonic-clonic secondary generalized seizure. The possibility of cardiac involvement in the pathogenesis of SUDEP has been suggested by many studies. Evaluation of this patient with EEG-video monitoring, including measurement of heart rate, contributed to an identification of ictal tachycardia that may have played a role in the SUDEP. Premature mortality seems to be increased in patients with epilepsy, and cardiac abnormalities may be a possible cause of SUDEP. (Cardiol J 2011; 18, 2: 194-196)

Illicit Opiate Abuse

Illicit opiate use, especially injected drugs, contributes to premature mortality and morbidity in many developed and developing societies. The economic costs of illicit drug use are substantial. Fatal overdoses and HIV/AIDS resulting from sharing dirty needles and injecting equipment are major contributors to mortality and morbidity. Illicit opioid use accounted for 0.7 percent of global disability–adjusted life years in 2000. An estimated 15.3 million people, or 0.4 percent of the world population ages 15 to 64, used illicit opioids in 2002, with more than half using heroin and the rest using opium or diverted pharmaceuticals such as buprenorphine, methadone, or morphine. The most popular interventions for illicit opioid dependence in many developed societies have been law enforcement efforts to interdict the drug supply and enforce legal sanctions against drug use. One consequence has been that illicit opioid users have been exposed to the least effective intervention: imprisonment for drug or property offenses. The most effective intervention to reduce blood–borne virus infection resulting from illicit drug injections is provision of clean injecting equipment to users. This intervention has been widely supported in developed countries, but less so in developing countries. In addition, vaccinations are effective against hepatitis B. In treatment settings, the most popular interventions have been detoxification and drug–free treatment, which has proven the least productive in retaining opioid–dependent people in treatment. Opioid agonists have a niche role in treatment of opioid dependence, especially if their efficacy improves with development of long–acting injectable forms of the drug.

Rastreio aos factores de risco modificáveis da doença isquémica da doença isquémica coronária no concelho de Faro

RESUMO: Introdução: As doenças cardiovasculares (DCV) são a principal causa de morbilidade, e mortalidade prematura em Portugal e na Europa. A sua causa é multifactorial e a maior parte dos casos resultam de factores de risco modificáveis. O cálculo do RCVG, pretende ser uma estimativa da probabilidade de desenvolver DCV. Este estudo pretende identificar e caracterizar indivíduos em risco de desenvolver doença isquémica coronária e respectivos factores de risco modificáveis, no Concelho de Faro e determinar a sua prevalência e calcular SCORE global de risco cardiovascular Material e métodos: Estudo, observacional transversal, que incluiu um total de 601 individuos, com idades entre os 40-64 anos de idade, residentes no concelho de Faro, inscritos no Centro de Saúde de Faro e que consistiu da avaliação da prevalência dos factores de risco modificáveis da doença isquémica coronária pela utilização de instrumentos específicos. Resultados e discussão: Foram incluídos 601 individuos de ambos os géneros. Trata-se de uma população potencialmente menos literada e num contexto social, cultural, familiar e profissional que, eventualmente, condicionará o estilo de vida e opções em saúde. 55,9% dos indivíduos tem HTA; 42,4 % dos indivíduos tem valor de colesterol total elevado, compatível com dislipidemia (cut off de 200mg/dl); 50,9 % (cut off 190 mg/dl); 8,7% tem valores de glicemia compatíveis com diabetes; 19,8 são fumadores; 72,7% apresenta excesso de peso/obesidade; 37,6% dos indivíduos tem baixo nível de actividade física; 20,1% dos indivíduos apresenta evidência de stress, ansiedade ou depressão, pela avaliação utilizando a EADS. Parece existir evidência de maior proporção de factores de risco entre os homens e uma proporção significativa de indivíduos com importantes factores de risco modificáveis em simultâneo. Mais de metade dos indivíduos tem 3 ou mais factores de risco em simultâneo, com o excesso de peso/obesidade, hipertensão e dislipidemia a serem os com mais comummente associados. 9,7% dos indivíduos tem risco entre 5-9% e apenas 29,3% tem SCORE inferior a 1%. Conclusões: A elevada prevalência dos factores de risco modificáveis e a elevada proporção de indivíduos identificados com esses factores, e com risco moderado e alto de DCV, parece justificar uma atenção redobrada a esse nível e um planeamento dos cuidados de saúde ajustados e específicos para esta realidade.----------------------- ABSTRACT: Introduction: Cardiovascular diseases are the leading cause of morbidity and premature mortality in Portugal and in Europe. The cause is multifactorial and in most cases results from modifiable risk factors. The global cardiovascular risk calculation is intended as an estimate of the likelihood of developing cardiovascular disease. This study aims to identify and characterize individuals at risk of developing ischemic heart disease and their modifiable risk factors in Faro, and determine its prevalence as well as to calculate global cardiovascular risk SCORE. Methodology: This was a cross sectional observational study, which included a total of 601 individuals, aged 40-64 years of age living in Faro, and enrolled atthe Health Centre of Faro. The prevalence of modifiable risk factors of disease ischemic heart was assessed once, after letter invitation, by the use of the following instruments (acrescentar os instrumentos). Data was analysed with (incluir testes estatisticos utilizados) Results and Discussion: We included 601 subjects of both genders. This is a potentially less literate population with a social, cultural and family contextwhich, may eventually constrain lifestyle and health choices. Almost sixty percent (55.9%) of the individuals have hypertension, 42,4% have high total cholesterol value, compatible with dyslipidemia, 8,7 % had blood glucose values compatible with diabetes, 19,8% are smokers, 72,7% are overweight or obese, 37,6% of individuals have low levels of physical activity, 20,1% of individual show evidence of stress, anxiety or depression, as assessed by using the DASS. There seems to be evidence of a greater proportion of risk factors among men and a significant proportion of individuals with major modifiable risk factores simultaneously. More than half of the studied individuals have three or more risk factors simultaneously, being excess weight / obesity, hypertension and dyslipidemia, the most commonly associated. Almost ten percent (9,7%) of the individuals have a risk between 5-9% and only 29,3% has a SCORE less than 1%. Conclusion: The high prevalence of modifiable risk factors and the high proportion of individuals identified with these factors, and with moderate and high risk of CVD, appear to justify further attention at this level and planning of health care interventions specifically adjusted to this reality.

Intervenção breve no tabagismo : abordagem clínica dos médicos portugueses

RESUMO - O tabagismo é o principal factor de risco evitável em saúde nos países europeus, contribuindo para o aumento da mortalidade prematura, estando associado a inúmeras doenças. A epidemia tabágica é uma preocupação em Saúde Pública, sendo essencial o investimento na sua prevenção e controlo. A cessação tabágica é uma das estratégias para o controlo desta epidemia, surgindo a intervenção breve como uma comprovada medida custo-efetiva. Contudo, e apesar das guidelines, a intervenção breve não está amplamente disseminada na prática clínica dos profissionais de saúde. Neste sentido, este estudo teve como objetivo avaliar as práticas clíniicas autoreportadas dos médicos portugueses na intervenção breve em tabagismo. É um estudo observacional descritivo transversal e exploratório. A amostra é constituída por médicos que participaram em duas conferências médicas distintas e que aceitaram responder a um questionário (n=549). O tratamento estatístico foi efetuado recorrendo ao Statistical Package for the Social Sciences (SPSS), versão 21. Foram efetuadas uma análise descritiva e inferencial, assim como uma regressão logística. Analisando os dados, os resultados apontam para a formação pós-graduada e a prática de cessação tabágica como dois fatores que influenciam positivamente a atuação dos médicos na intervenção breve. A intervenção breve é fundamental para aumentar as taxas de cessação tabágica. Para que a implementação seja eficaz é necessário apostar na formação pré e pós-graduada dos médicos e outros profissionais de saúde, associando essa formação ao treino prático que possibilite o desenvolvimento de competências específicas.

A criação de unidades locais de saúde na região Alentejo : impacto na mortalidade precoce hospitalar

RESUMO - Introdução: A integração de cuidados de saúde tem sido o modelo organizacional procurado para ajudar os sistemas de saúde a ultrapassar os constantes desafios impostos e para obterem ganhos na qualidade dos cuidados e nos resultados para os utentes. A taxa de mortalidade precoce no ambiente hospitalar é um indicador que permite avaliar a performance dos sistemas de saúde, refletindo os resultados em saúde. Esta é expressa a partir do cálculo dos anos de vida potencialmente perdidos (AVPP). Objetivo: Avaliar o impacto da criação de Unidades Locais de Saúde (ULS) na região Alentejo. Metodologia: Em primeiro lugar determinou-se a taxa de mortalidade precoce em ambiente hospitalar e os respetivos AVPP, analisando os diagnósticos principais associados, entre 2000 e 2011, nas ULS do Norte Alentejano e Baixo Alentejo. Para calcular o impacto da criação das ULS nos AVPP foi realizado o método Difference in Difference. Resultados: Foram analisados 605 825 episódios de internamento, dos quais 5258 (0,87%) resultaram em óbito hospitalar em utentes com <70 anos. Desta análise resultaram 102 270 AVPP para ambos os sexos. Após a criação das ULS do Norte Alentejano e Baixo Alentejo, verificou-se uma diminuição no número de AVPP de – 2, 7% e – 2, 6% respetivamente. Conclusões: Com a criação das ULS na região de saúde do Alentejo, o número de AVPP em ambiente hospitalar diminuiu, no entanto torna-se necessário aumentar a população em estudo e incluir mais variáveis que possam influenciar os AVPP por forma a retirarem-se conclusões mais específicas.

Custos indirectos associados à obesidade em Portugal

RESUMO - A obesidade constitui um importante problema de saúde pública com consequências económicas de grande dimensão. Os obesos têm um risco acrescido de contrair doenças e de sofrer morte prematura devido a problemas como a diabetes, hipertensão arterial, AVC, insuficiência cardíaca e algumas neoplasias malignas. O presente estudo tem como objectivo estimar o custo económico indirecto (valor da produção perdida) associado à obesidade em Portugal no ano de 2002. O estudo adopta uma abordagem tipo custos da doença baseada na prevalência. Os dados são retirados do Inquérito Nacional de Saúde e estatísticas de rotina publicadas pelo INE e por outros organismos oficiais. Consideram-se como obesas pessoas com índice de massa corporal (IMC) ≥ 30 kg/m2 e estabelecem-se como limites etários para participação em actividades económicas produtivas as idades compreendidas entre os 15 e os 64 anos. A estratégia de imputação de custos ao factor de risco obesidade caracteriza- se por estimar, para a população portuguesa, as proporções de doença e morte prematura atribuíveis à obesidade e em multiplicar as estimativas populacionais encontradas pelo valor da produtividade económica potencial das pessoas afectadas. O custo indirecto total da obesidade em Portugal no ano de 2002 foi estimado em 199,8 milhões de euros. A mortalidade contribuiu com 58,4% deste valor (117 milhões de euros) e a morbilidade com 41,6% (83 milhões de euros). Os custos da morbilidade advêm de mais de 1,6 milhões de dias de incapacidade anuais, principalmente por faltas ao trabalho associadas a doenças do sistema circulatório e diabetes tipo II. Os custos da mortalidade são o resultado de 18 733 potenciais anos de vida activa perdidos, numa razão de 3 mortes masculinas por cada morte feminina. Os resultados indicam que a obesidade acarreta consideráveis perdas económicas para o país. Comparando os resultados com um estudo complementar que calculou os custos directos (em cuidados de saúde) da obesidade, verifica-se que a componente indirecta representa 40,2% do total dos custos da obesidade. A implementação de estratégias que prevenissem ou reduzissem a incidência e prevalência de obesidade em Portugal poderia gerar ganhos de produtividade elevados. Para conhecer a dimensão destes ganhos é necessária mais investigação sobre os benefícios clínicos e relação custo-efectividade de estratégias para a redução da obesidade.

Whole-person care: from rhetoric to reality. Achieving parity between mental and physical health.

The report presents evidence on a range of factors affecting disparity between mental and physical health, and includes case studies and examples of good practice to illustrate some of the key issues and solutions. It should be seen as the first stage of an on-going process over the next 5"10 years that will deliver parity for mental health and make whole-person care a reality. It builds on the Implementation Framework for the Mental Health Strategy in providing further analysis of why parity does not currently exist, and the actions required to bring it about. A parity approach should enable NHS and local authority health and social care services to provide a holistic, whole person response to each individual, whatever their needs, and should ensure that all publicly funded services, including those provided by private organisations, give people's mental health equal status to their physical health needs. Central to this approach is the fact that there is a strong relationship between mental health and physical health, and that this influence works in both directions. Poor mental health is associated with a greater risk of physical health problems, and poor physical health is associated with a greater risk of mental health problems. Mental health affects physical health and vice versa. The report makes a series of key recommendations for the UK government, policy-makers and health professionals. Recommendations include: The government and the NHS Commissioning Board should work together to give people equivalent levels of access to treatment for mental health problems as for physical health problems, agreed standards for waiting times, and agreed standards for emergency/crisis mental healthcare. Action to promote good mental health and to address mental health problems needs to start at the earliest stage of a person's life and continue throughout the life course. Preventing premature mortality " there must be a major focus on improving the physical health of people with mental health problems. Public health programmes must include a focus on the mental health dimension of issues commonly considered as physical health concerns, such as smoking, obesity and substance misuse. Commissioners need to regard liaison doctors (who work across physical and mental healthcare) as an absolute necessity rather than an optional luxury. NHS and social care commissioners should commission liaison psychiatry and liaison physician services to drive a whole-person, integrated approach to healthcare in acute, secure, primary care and community settings, for all ages. Mental health services and mental health research must receive funding that reflects the prevalence of mental health problems and their cost to society. Mental illness is responsible for the largest proportion of the disease burden in the UK (22.8%), larger than that of cardiovascular disease (16.2%) or cancer (15.9%). However, only 11% of the NHS budget was spent on NHS services to treat mental health problems for all ages during 2010/11. Culture, attitudes and stigma " zero-tolerance policies in relation to discriminatory attitudes or behaviours should be introduced in all health settings to help combat the stigma that is still attached to mental illness within medicine. Political and managerial leadership is required at all levels. There should be a mechanism at national level for driving a parity approach to relevant policy areas across government; all local councils should have a lead councillor for mental health; all providers of specialist mental health services should have a board-level lead for physical health and all providers of physical healthcare services should have a board-level lead for mental health. The General Medical Council (GMC) and Nursing and Midwifery Council (NMC) should consider how medical and nursing study and training could give greater emphasis to mental health. Mental and physical health should be integrated within undergraduate medical education.This resource was contributed by The National Documentation Centre on Drug Use.

Tackling inequalities in life expectancy in areas with the worst health and deprivation: England

While overall health outcomes in England has improved during the last Labour administration - inequalities in health has increased, according to the latest report published by the House of Commons Public Accounts Committee today. People living in the poorest communities in England are more likely to die two years earlier than people living in more affluent neighbourhoods, leading to 3,335 premature mortality the report claims. Between, 1997 and 2010, the NHS budget has doubled and the country is more prosperous than ever before, yet the gap in life expectancy between the poorest areas and the national average grew by 7% for men and 14% for women, the committee concluded.

Health inequality target monitoring: update to include data for 2006

These reports summarise progress against Department of Health inequality targets for 2010 in the following areas: Infant mortality; life expectancy at birth for males and for females; cancer (premature mortality rate) and all circulatory diseases (premature mortality rate). Key facts Infant mortality The inequality gap in the infant mortality rate has reduced for the second consecutive period, though not yet by a sufficient amount to meet the target, based on the trend since the current socio economic classifications were introduced in 2001. Life expectancy at birth (males and females) The inequality gaps in male and female life expectancy at birth have both increased since the baseline. If current trends continue, the target would not be met. Cancer mortality The inequality gap in cancer mortality has declined since the baseline (despite a slight increase in the latest period), and the minimum requirement for the 2010 target has already been met. All circulatory diseases mortality The inequality gap in circulatory disease mortality has declined, and is on track to meet the target.

Factors associated with improvement in disability-adjusted life years in patients with HIV/AIDS

Background The epidemic of HIV/AIDS and treatments that have emerged to alleviate, have brought about a shift in the burden of disease from death to quality of life/disability. The aim was to determine which factors are associated with improvements in the level of health of male and female patients with HIV/AIDS in Andalusia, in terms of disability-adjusted life years. Methods Descriptive study based on a sample group of 8800 people on the Andalusian AIDS register between 1983 and 2004. Dependent variables: Life lost due to premature mortality (YLL), years lost due to disability (YLD) and disability-adjusted life years (DALY). Independent variables: vital state, sex, age at the time of diagnosis, age at the time of death, transmission category, province of residence, AIDS-indicator disease and the period of diagnosis. A bivariate analysis was carried out to find out if the health level variables changed in accordance with the independent variables. Using the independent variables which had a statistically significant link with the level of health variables, a multivariate linear regression model, disaggregated by gender, was constructed. Results Amongst the women, we found a model which explained the level of health of 64.9%: a link was found between a higher level of health (lower DALYs) and not intravenous drug use, the province of residence, being diagnosed during the HAART era and older age at the time of diagnosis. Amongst the men, we found a model which explained the level of health of 64.4%: a link was found between a higher level of health (lower DALYs) and intravenous drug use, the province of residence, being diagnosed during the HAART era and older age at the time of diagnosis. Conclusion A higher level of health (lower DALY) amongst both men and women was found to be linked to not be intravenous drug user, the province of residence, being diagnosed during the HAART era and older age at the time of diagnosis.

Sudden death among young people with first-episode psychosis: an 8-10 year follow-up study.

Individuals with first episode psychosis (FEP) experience high rates of premature mortality, in particular due to suicide. The study aims were to: a) Estimate the rate of sudden death among young people with FEP during an 8-10 year period following commencement of treatment; b) Examine and describe the socio-demographic and clinical characteristics associated with sudden death; and c) Examine the timing of death in relation to psychiatric treatment.This was a cohort study. The sample comprised 661 patients accepted into treatment at the Early Psychosis Prevention and Intervention Centre between 1/1/1998 and 31/12/2000. Demographic and clinical data were collected by examination of the medical files. Mortality data were collected via a search of the National Coroners Information System; the Victorian State Coroner's office and clinical files. Nineteen patients died and just over two thirds of deaths were classified as intentional self-harm or suicide. Death was associated with male gender, previous suicide attempt and greater symptom severity at last contact. People with FEP are at increased risk of premature death, in particular suicide. A previous suicide attempt was very common amongst those who died, suggesting that future research could focus upon the development of interventions for young people with FEP who engage in suicidal behaviour.

A set of indicators for decomposing the secular increase of life expectancy.

ABSTRACT: BACKGROUND: The ongoing increase in life expectancy in developed countries is associated with changes in the shape of the survival curve. These changes can be characterized by two main, distinct components: (i) the decline in premature mortality, i.e., the concentration of deaths around some high value of the mean age at death, also termed rectangularization of the survival curve; and (ii) the increase of this mean age at death, i.e., longevity, which directly reflects the reduction of mortality at advanced ages. Several recent observations suggest that both mechanisms are simultaneously taking place. METHODS: We propose a set of indicators aiming to quantify, disentangle, and compare the respective contribution of rectangularization and longevity increase to the secular increase of life expectancy. These indicators, based on a nonparametric approach, are easy to implement. RESULTS: We illustrate the method with the evolution of the Swiss mortality data between 1876 and 2006. Using our approach, we are able to say that the increase in longevity and rectangularization explain each about 50% of the secular increase of life expectancy. CONCLUSION: Our method may provide a useful tool to assess whether the contribution of rectangularization to the secular increase of life expectancy will remain around 50% or whether it will be increasing in the next few years, and thus whether concentration of mortality will eventually take place against some ultimate biological limit.

Insulin dysfunction and allostic load in bipolar disorder

Bipolar disorder (BD) is associated with substantial morbidity, as well as premature mortality. Available evidence indicates that 'stress-sensitive' chronic medical disorders, such as cardiovascular disease, obesity and Type 2 diabetes mellitus, are critical mediators and/or moderators of BD. Changes in physiologic systems implicated in allostasis have been proposed to impact brain structures and neurocognition, as well as medical comorbidity in this population. For example, abnormalities in insulin physiology, for example, insulin resistance, hyperinsulinemia and central insulinopenia, are implicated as effectors of allostatic load in BD. Insulin's critical role in CNS physiological (e.g., neurotrophism and synaptic plasticity) and pathophysiological (e.g., neurocognitive deficits, pro-apoptosis and amyloid deposition) processes is amply documented. This article introduces the concept that insulin is a mediator of allostatic load in the BD and possibly a therapeutic target.

Screening for cardiovascular disease risk and subsequent management in low and middle income countries : challenges and opportunities

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the leading cause of premature mortality in low and middle income countries (LMICs). Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisectoral population-based interventions to reduce CVD risk factors in the entire population. Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs. Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability of affordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). This also emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
