A Study of Alcohol Problems and Marriage from a Treatment Perspective

This thesis is concerned with alcohol problems and marital relationships. It is particularly interested in these dynamics from a treatment perspective. The study addresses theory, research and clinical practice in the field of alcohol problems. It specifically considers these areas as they relate to enhancing understanding of the dynamics between alcohol problems and marriage. The study examines three theoretical paradigms, the disease concept of addiction, behavioural/cognitive behavioural and systems based approaches to understanding alcohol addiction. This provides a multiple theory base from which research in the field and the clinical data collected in the current research is analysed and interpreted. The study reviews research findings that have contributed to the recognition of marital treatment interventions as significant in the alcohol field. It highlights the discrepancies between such research findings and developments in actual clinical practice. In doing so, the study illustrates the gap between theory, research and clinical practice. The need for a more effective framework of information exchange across these areas of activity is identified and a model for better exchange is presented and discussed. This model highlights the importance of including clients' experiences to influence policy, practice, theory and research. In the research, specific attention is focused on the experiences of couples in alcohol treatment. Clinical data is collected from a series of alcohol treatment couples group therapy sessions. The research analysis of the clinical data identifies and extracts concerns as expressed by couples in treatment. Interpretation of these identified concerns or themes is conducted by employing the theoretical constructs of the three selected theoretical paradigms in conjunction with group work theory. On the basis of the findings in this thesis a model for a maritally sensitive assessment framework is developed. The model identifies a number of factors that should be considered in order to enhance appreciation of the interaction between alcohol problems and marital dynamics. This has particular significance for treatment interventions.This resource was contributed by The National Documentation Centre on Drug Use.

Drug Misuse in Dublin, July 1982

In this report for the Medico Social Research Board the author provides an overview of the drug problem in Dublin's inner city. On 12-14 July 1982 the author visited the Sean Mac Dermott street area of the inner city, the Eastern Health Board, Coolmine Community, Jervis Street Drug Advisory and Treatment Centre and the Garda drug squad. From these interviews, the author concludes that Dublin's inner city has a serious problem with drug use, in particular the injecting of heroin. Heroin addicts steal on a regular basis to fund their habit, and frequently inject themselves in public spaces of local authority flat complexes. Despite the best efforts of the support services (Social workers, doctors, Gardai and clergy) there is a high prevalence of injecting heroin use. There has also been abuse of prescription services. Addicts frequently seek opiates from a small number of doctors who are willing to prescribe. Drug education is severely lacking or inappropriate, according to the author, and the Garda drug squad is severely over stretched. While cannabis use is said to be prevalent in Dublin's two universities, drug use has been most problematic in the deprived parts of the city. The author presents the drug epidemic, which has developed over the last two years, in moral terms, and wonders if Christian society, in particular the Catholic Church, and the health authorities can do anything to stop the crisis from worsening. Recommendations include; conducting epidemiological surveys to determine the true extent of the problem, cross disciplinary co-operation, greater drug awareness through education, and more rehabilitation units.This resource was contributed by The National Documentation Centre on Drug Use.

A Study of the Epidemiology of AIDS in Ireland and an Evaluation of an AIDS Education Programme in Second-level Schools

Second-level school students have been identified by the Minister for health as a priority group for education on AIDS. An education programme was accordingly initiated in 1988 in Community Care Area 1 in South county Dublin. This report evaluates this education intervention by means of pre- and post- intervention questionnaires. The questionnaire examined knowledge and attitudes of students relevant to AIDS. The results showed that the level of knowledge of students living in this area was high prior to intervention. The education programme succeeded in improving some aspects of knowledge and also influenced some attitudes of the students. A study of the epidemiology of Aids in Ireland reveals that the epidemic is at a relatively early stage with a consequent rapid doubling time of 9-10 months. In comparison with most developed countries Ireland has a high proportion of AIDS cases occurring among intravenous drug abusers and directly related to this a high number of HIV infected children. Examination of the literature reveals that behaviour change has occurred most noticeably among the homosexual/bisexual risk group. There is some evidence that the comprehensive programmes can achieve change in the behaviour of intravenous drug abusers. There are very few reports linking behaviour change among adolescents and young adults to education programmes. Much of the available literature relates to changes in knowledge and attitudes. International recommendations on the nature of the ideal health education intervention on AIDS are reviewed. The importance of a comprehensive health education programme which incorporates AIDS education and which commences early in youth is noted. The role of the community physician in relation to education programmes and other aspects of monitoring and management of the AIDS epidemic is discussed.This resource was contributed by The National Documentation Centre on Drug Use.

A study of cocaine use in Northern Ireland 2009.

This study explored the patterns of cocaine use and the lifestyles of users in Northern Ireland with the aim of providing the Department of Health, Social Services and Public Safety (DHSSPS) and treatment service providers with a better understanding of cocaine use in Northern Ireland. This primarily qualitative study was conducted in two phases. In Phase I a â?~Community Assessment Processâ?T was conducted to gain an understanding of the experiences of drug treatment professionals to cocaine use in Northern Ireland. In phase II 40 in-depth interviews were conducted with cocaine users. The study identified two types of cocaine user, these are recreational or socially integrated users and those referred for drug treatment who as a group was socially marginalized users. For the purposes of this study these users will be referred to as either recreational or treatment users. The demographic profiles of each type of user differed in a number of important respects. The recreational users were typically young, educated and anchored to a largely conventional lifestyle and whose pattern of non-work activities involved partying and drug use. Treatment users, on the other hand, generally had low level educational qualifications and were typically unemployed and living on state benefits. A number of the treatment users were either living in a hostel at the time of interview or had experienced homelessness at some time in their life. None of the recreational users reported any experience of homelessness. These distinctions, as well as differences between the groups in terms of their drug use patterns, preferences and practices, strongly suggest that in unravelling the nature of cocaine use and cocaine problems there is a need to look beyond the drug itself.This resource was contributed by The National Documentation Centre on Drug Use.

Does income inequality cause health and social problems?

Key points• The literature shows general agreement about a correlation between income inequality and health/social problems. • There is less agreement about whether income inequality causes health and social problems independently of other factors, but some rigorous studies have found evidence of this. • The independent effect of income inequality on health/social problems shown in some studies looks small in statistical terms. But these studies cover whole populations, and hence a significant number of lives. • Some research suggests that inequality is particularly harmful beyond a certain threshold. Britain was below this threshold in the 1960s, 1970s and early 1980s, but rose past it in 1986–7 and has settled well above it since 1998–9. If the threshold is significant it could provide a target for policy. • Anxiety about status might explain income inequality’s effect on health and social problems. If so, inequality is harmful because it places people in a hierarchy which increases competition for status, causing stress and leading to poor health and other negative outcomes. • Not all research shows an independent effect of income inequality on health/social problems. Some highlights the role of individual income (poverty/material circumstances), culture/history, ethnicity and welfare state institutions/social policies. • The author concludes that there is a strong case for further research on income inequality and discussion of the policy implications.This resource was contributed by The National Documentation Centre on Drug Use.

Growing up in Ireland. Key findings: infant cohort (at 3 years).

 The latest results from the study paint a picture of how these families are faring across a range of areas in their lives including their health, family life and financial and economic circumstances. In general the findings show that three-year-olds in Ireland are in good health with a few notable public health and related issues (including overweight and obesity), there is overall stability in family structures over the short term and that the recession has had a substantial effect on families with young children over the last number of years. These are the first longitudinal findings from the study. The first wave of fieldwork with the families of the Infant Cohort included approximately 11,100 nine-month-olds, their parents and carers. Interviews began in September 2008 and were completed in March 2009. Interviews for the second round of interviews with this cohort took place between January and August 2011. A total of 90% of the original sample of nine-month-olds were successfully re-interviewed. (A full download of the results released today, presented in three briefing documents can be found by clicking here. Key findings include: Health â?¢ Most of the children were described as being in good health; 75% were rated as very healthy and a further 23% were rated as healthy, but a few minor problems. Girls were more likely to be reported as very healthy (78%) compared with boys (72%). â?¢ One in four or almost one quarter of three-year-old children were overweight (19%) or obese (6%). â?¢ Childrenâ?Ts weight was related to household social class. 5% of children in families in the professional/managerial group were classified as obese at three years of age compared with 9% of those in the most disadvantaged social class group. However, at least one-fifth of children in every social class were overweight. â?¢ Childrens consumption of energy-dense foods such as crisps, sweets, chips, and non-diet fizzy drinks increased as parental education fell. 63% of children whose mother had a lower secondary education or less ate at least one portion of crisps compared with 36% of those from degree-level backgrounds, although consumption of biscuits/chocolates was over 70% for both groups of children. â?¢ Two-thirds (66%) of three-year-olds had received at least one course of antibiotics in the 12 months preceding the interview. Children with a full medical card (35% of the sample) or a GP-only medical card (5% of the sample) were more likely to have received a course of antibiotics than â?¢ Children with a full medical card received a higher number of antibiotic courses on average (2.6) compared with those without a medical card (2.1). â?¢ Just under 16% of three-year-old children were reported as having at least one longstanding illness, condition or disability. The most commonly reported illness types included Asthma (5.8%), Eczema/Skin allergies (3.9%) and Food/digestive allergies (1.2%) Family Life and Childcare â?¢ While the overall distribution of family structure was stable, there have been transitions from one-parent families to two-parent families and vice-versa over the 27 months between interview â?" approximately 2 to 3 percent in each direction. â?¢ 50% of three year olds were in some form of non-parental childcare for eight or more hours a week. The most common form used was centre-based childcare which almost tripled between nine months and three years, from 11% to 30%. â?¢ A similar percentage of grandparents were caring for children at both nine months and three years, 12% and 11% respectively. A total of 10% of three-year-olds were being minded by a childminder, an increase of 3 percentage points from when the children were nine months of age. â?¢ Children who were in some form of non-parental childcare were spending an average of 23 hours a week in their main type of childcare. â?¢ At time of interview the vast majority of mothers reported that they had regular contact with the Study Childâ?Ts grandparents (91%). In offering support to parents, grandparents were most likely to babysit (50%), and buy clothes (40%) at least on a monthly basis. One-parent families were more likely than two-parent families to receive financial support from grandparents with just under one-third (66%) of one-parent families receiving financial support from grandparents at least once every three months. â?¢ The most frequently used discipline technique was â?~discussing or explaining why the behaviour was wrongâ?T, with 63% of mothers saying they always did this. â?¢ 12% of mothers said they used â?~smackingâ?T as a form of discipline now and again and less than 1% used â?~smackingâ?T as a form of discipline more frequently. Over half reported that they never smacked the Study Child. Financial and Economic Circumstances â?¢ Just over half (53%) of mothers of three-year-olds worked outside the home, 38% said they were on home duties and 6% said they were unemployed. â?¢ The biggest change in terms of the work status of three-year-oldsâ?T parents was an increase in the percentage of unemployed fathers â?" 6% when the child was nine months rising to almost 14% when s/he was three years of age. â?¢ 61% of families of three-year-olds reported experiencing difficulties in making â?~ends meetâ?T. This was a substantial increase from 44% in the first round of interviews when the children were nine-months-old. â?¢ Almost two thirds (63%) of all families with three-year-olds reported that the recession had had a very significant or significant effect on them. â?¢ The most frequently recorded effects were: a reduction in wages (63%); canâ?Tt afford luxuries (54%), social welfare reduction (53%) and canâ?Tt afford/cut back on basics (32%). Growing Up in Ireland is a Government funded study tracking the development of two nationally representative cohorts of children: an Infant Cohort which was interviewed initially at nine months and subsequently at three years of age; and a Child Cohort which was interviewed initially at nine years and subsequently at 13 years of age. The study is being conducted by a consortium of researchers led by the Economic and Social Research Institute (ESRI) and Trinity College Dublin.

Mental health and growing up factsheet. Cannabis and mental health: information for young people.

About this leaflet This is one in a series of leaflets for parents, teachers and young people entitled Mental Health and Growing Up. These leaflets aim to provide practical, up-to-date information about mental health problems (emotional, behavioural and psychiatric disorders) that can affect children and young people. This leaflet gives you some basic facts about cannabis and also how it might affect your mental health. Introduction Lots of young people want to know about drugs. Often, people around you are taking them, and you may wonder how it will make you feel. You may even feel under pressure to use drugs in order to fit in, or be â?~coolâ?T. You may have heard that cannabis is no worse than cigarettes, or that it is harmless. What is cannabis? The cannabis plant is a member of the nettle family that has grown wild throughout the world for centuries. People have used it for lots of reasons, other than the popular relaxing effect. It comes in two main forms: ï,§ resin, which is a brown black lump also known as bhang, ganja or hashish ï,§ herbal cannabis, which is made up of the dried leaves and flowering tops, and is known as grass, marijuana, spliff, weed, etc. Skunk cannabis is made from a cannabis plant that has more active chemicals in it (THC), and the effect on your brain is stronger. Because â?~streetâ?T cannabis varies so much in strength, you will not be able to tell exactly how it will make you feel at any particular time. What does it do to you? When you smoke cannabis, the active compounds reach your brain quickly through your bloodstream. It then binds/sticks to a special receptor in your brain. This causes your nerve cells to release different chemicals, and causes the effects that you feel. These effects can be enjoyable or unpleasant. Often the bad effects take longer to appear than the pleasant ones. ï,§ Good/pleasant effects: You may feel relaxed and talkative, and colours or music may seem more intense. ï,§ Unpleasant effects: Feeling sick/panicky, feeling paranoid or hearing voices, feeling depressed and unmotivated. Unfortunately, some people can find cannabis addictive and so have trouble stopping use even when they are not enjoying it. The effects on your mental health Using cannabis triggers mental health problems in people who seemed to be well before, or it can worsen any mental health problems you already have. Research has shown that people who are already at risk of developing mental health problems are more likely to start showing symptoms of mental illness if they use cannabis regularly. For example if someone in your family has depression or schizophrenia, you are at higher risk of getting these illness when you use cannabis. The younger you are when you start using it, the more you may be at risk. This is because your brain is still developing and can be more easily damaged by the active chemicals in cannabis. If you stop using cannabis once you have started to show symptoms of mental illness, such as depression, paranoia or hearing voices, these symptoms may go away. However, not everyone will get better just by stopping smoking. If you go on using cannabis, the symptoms can get worse. It can also make any treatment that your doctor might prescribe for you, work less well. Your illness may come back more quickly, and more often if you continue to use cannabis once you get well again. Some people with mental health problems find that using cannabis makes them feel a bit better for a while. Unfortunately this does not last, and it does nothing to treat the illness. In fact, it may delay you from getting help you need and the illness may get worse in the longer term.

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.

Assessing attachment cognitions and their associations with depression in youth with eating or drug misuse disorders.

The study investigates associations between attachment cognitions and depression symptoms in 71 15-25-year-olds, 26 of whom have eating disorders, and 20 of whom are drug misusers. Attachment cognitions were measured with the CaMir Q-sort, which provides indexes for secure, avoidant, and preoccupied attachment, as well as scores on 13 dimensions. The BDI-13 was used to measure depressive symptomatology. Consistent with the literature, BDI scores were associated with cognitions of preoccupied attachment. They were also related to cognitions of avoidant attachment, confirming Bowlby's theory on defensive exclusion. For participants with eating disorders, depressive symptomatology was related to preoccupation and parental interference, whereas for drug misusers, it was negatively related to security, preoccupation, parental support, and lack of parental concern. These findings help understand how attachment cognitions may participate in depressive symptomatology, namely in youth whose behavior problems may be associated with specific attachment experiences.

Interest of qualitative and quantitative profiling of endocannabinoids for evaluation of their implication in drug addiction process

Introduction: In the middle of the 90's, the discovery of endogenous ligands for cannabinoid receptors opened a new era in this research field. Amides and esters of arachidonic acid have been identified as these endogenous ligands. Arachidonoylethanolamide (anandamide or AEA) and 2-Arachidonoylglycerol (2-AG) seem to be the most important of these lipid messengers. In addition, virodhamine (VA), noladin ether (2-AGE), and N-arachidonoyl dopamine (NADA) have been shown to bind to CB receptors with varying affinities. During recent years, it has become more evident that the EC system is part of fundamental regulatory mechanisms in many physiological processes such as stress and anxiety responses, depression, anorexia and bulimia, schizophrenia disorders, neuroprotection, Parkinson disease, anti-proliferative effects on cancer cells, drug addiction, and atherosclerosis. Aims: This work presents the problematic of EC analysis and the input of Information Dependant Acquisition based on hybrid triple quadrupole linear ion trap (QqQLIT) system for the profiling of these lipid mediators. Methods: The method was developed on a LC Ultimate 3000 series (Dionex, Sunnyvale, CA, USA) coupled to a QTrap 4000 system (Applied biosystems, Concord, ON, Canada). The ECs were separated on an XTerra C18 MS column (50 × 3.0 mm i.d., 3.5 μm) with a 5 min gradient elution. For confirmatory analysis, an information-dependant acquisition experiment was performed with selected reaction monitoring (SRM) as survey scan and enhanced produced ion (EPI) as dependant scan. Results: The assay was found to be linear in the concentration range of 0.1-5 ng/mL for AEA, 0.3-5 ng/mL for VA, 2-AGE, and NADA and 1-20 ng/mL for 2-AG using 0.5 mL of plasma. Repeatability and intermediate precision were found less than 15% over the tested concentration ranges. Under non-pathophysiological conditions, only AEA and 2-AG were actually detected in plasma with concentration ranges going from 104 to 537 pg/mL and from 2160 to 3990 pg/mL respectively. We have particularly focused our scopes on the evaluation of EC level changes in biological matrices through drug addiction and atherosclerosis processes. We will present preliminary data obtained during pilot study after administration of cannabis on human patients. Conclusion: ECs have been shown to play a key role in regulation of many pathophysiological processes. Medical research in these different fields continues to growth in order to understand and to highlight the predominant role of EC in the CNS and peripheral tissues signalisation. The profiling of these lipids needs to develop rapid, highly sensitive and selective analytical methods.

Cytostatic lung perfusion results in heterogeneous spatial regional blood flow and drug distribution: evaluation of different cytostatic lung perfusion techniques in a porcine model.

OBJECTIVES: Comparison of doxorubicin uptake, leakage and spatial regional blood flow, and drug distribution was made for antegrade, retrograde, combined antegrade and retrograde isolated lung perfusion, and pulmonary artery infusion by endovascular inflow occlusion (blood flow occlusion), as opposed to intravenous administration in a porcine model. METHODS: White pigs underwent single-pass lung perfusion with doxorubicin (320 mug/mL), labeled 99mTc-microspheres, and Indian ink. Visual assessment of the ink distribution and perfusion scintigraphy of the perfused lung was performed. 99mTc activity and doxorubicin levels were measured by gamma counting and high-performance liquid chromatography on 15 tissue samples from each perfused lung at predetermined localizations. RESULTS: Overall doxorubicin uptake in the perfused lung was significantly higher (P = .001) and the plasma concentration was significantly lower (P < .0001) after all isolated lung perfusion techniques, compared with intravenous administration, without differences between them. Pulmonary artery infusion (blood flow occlusion) showed an equally high doxorubicin uptake in the perfused lung but a higher systemic leakage than surgical isolated lung perfusion (P < .0001). The geometric coefficients of variation of the doxorubicin lung tissue levels were 175%, 279%, 226%, and 151% for antegrade, retrograde, combined antegrade and retrograde isolated lung perfusion, and pulmonary artery infusion by endovascular inflow occlusion (blood flow occlusion), respectively, compared with 51% for intravenous administration (P = .09). 99mTc activity measurements of the samples paralleled the doxorubicin level measurements, indicating a trend to a more heterogeneous spatial regional blood flow and drug distribution after isolated lung perfusion and blood flow occlusion compared with intravenous administration. CONCLUSIONS: Cytostatic lung perfusion results in a high overall doxorubicin uptake, which is, however, heterogeneously distributed within the perfused lung.

Cleaning up neighbourhoods - Environmental Problems and Service Provision in Deprived areas

There has been growing concern that the quality of public services can be affected by the nature and scale of problems in deprived neighbourhoods and that poor services can contribute to a widening gap۪ between deprived and non-deprived neighbourhoods. There is also an increased emphasis within national policy on the quality of neighbourhood environments the so-called liveability۪ agenda. This report explores the challenges of delivering street scene۪ environmental services such as street sweeping and refuse collection in deprived and less deprived areas and examines the gap in environmental amenity between these different neighbourhoods. It also contributes to our understanding of the interplay between poor services and neighbourhood decline. The research involved a telephone survey of chief officers in local authority environmental service departments across the UK and detailed case studies of policy and practice in environmental service provision in four local authorities with significant levels of deprivation. Each case study involved work in three neighbourhoods within the authority two deprived and one less deprived as well as focus groups with residents and frontline environmental operatives, interviews with senior council staff and observation on the ground

Party drug use in techno nights: a field survey among French-speaking Swiss attendees.

This study was designed to investigate the lifestyle and substance use habits of dance music event attendees together with their attitudes toward prevention of substance misuse, harm reduction measures and health-care resources. A total of 302 attendees aged 16-46 years (mean=22.70, S.D.=4.65) were randomly recruited as they entered dance music events. Rates for lifetime and current use (last 30 days) were particularly high for alcohol (95.3% and 86.6%, respectively), cannabis (68.8% and 53.8%, respectively), ecstasy (40.4% and 22.7%, respectively) and cocaine (35.9% and 20.7%, respectively). Several patterns of substance use could be identified: 52% were alcohol and/or cannabis only users, 42% were occasional poly-drug users and 6% were daily poly-drug users. No significant difference was observed between substance use patterns according to gender. Pure techno and open-air events attracted heavier drug users. Psychological problems (such as depressed mood, sleeping problems and anxiety attacks), social problems, dental disorders, accidents and emergency treatment episodes were strongly related to party drug use. Party drug users appeared to be particularly receptive to harm reduction measures, such as on-site emergency staff, pill testing and the availability of cool water, and to prevention of drug use provided via counseling. The greater the involvement in party drug use, the greater the need for prevention personnel to be available for counseling. General practitioners appeared to be key professionals for accessing health-care resources.

Evaluation of rapid alternative methods for drug susceptibility testing in clinical isolates of Mycobacterium tuberculosis

A study was carried out to compare the performance of a commercial method (MGIT) and four inexpensive drug susceptibility methods: nitrate reductase assay (NRA), microscopic observation drug susceptibility (MODS) assay, MTT test, and broth microdilution method (BMM). A total of 64 clinical isolates of Mycobacterium tuberculosis were studied. The Lowenstein-Jensen proportion method (PM) was used as gold standard. MGIT, NRA, MODS, and MTT results were available on an average of less than 10 days, whereas BMM results could be reported in about 20 days. Most of the evaluated tests showed excellent performance for isoniazid and rifampicin, with sensitivity and specificity values > 90%. With most of the assays, sensitivity for ethambutol was low (62-87%) whereas for streptomycin, sensitivity values ranged from 84 to 100%; NRA-discrepancies were associated with cultures with a low proportion of EMB-resistant organisms while most discrepancies with quantitative tests (MMT and BMM) were seen with isolates whose minimal inhibitory concentrations fell close the cutoff. MGIT is reliable but still expensive. NRA is the most inexpensive and easiest method to perform without changing the organization of the routine PM laboratory performance. While MODS, MTT, and BMM, have the disadvantage from the point of view of biosafety, they offer the possibility of detecting partial resistant strains. This study shows a very good level of agreement of the four low-cost methods compared to the PM for rapid detection of isoniazid, rifampicin and streptomycin resistance (Kappa values > 0.8); more standardization is needed for ethambutol.

Changes in antihypertensive drug treatment in the general population: the Colaus Study

Background and aims: there is little information regar ding changes in antihypertensive drug treatment in Switzerland. We aimed at assessing those changes in a population-based, prospective study. Methods: 768 hypertensive subjects (372 women, 397 men) followed for 5 years. Subjects were defined as continuers (no change), switchers (one antihypertensive class replace by another), combiners (one antihypertensive class added) and discontinuers (stopped treatment). Results: Analysis of all patients (mono or combination therapy) showed that 54.6% were continuers, 27.2% combiners, 12.9% switchers and 5.3 % discontinuers. Similar findings were obtained for participants on monotherapy only: 42.2% continuers, 36.7% combiners, 13.4% switchers and 7.7% discontinuers. Combiners had higher systolic and diastolic blood pressure values at baseline than the other groups (p<0.001), while no difference were found for personal and family history and other clinical and biological variables. Compared to continuers, combiners and switchers improved their blood pressure status at follow-up: 26.7% of combiners and 26.3% of switchers improved, versus 17.7% of continuers and 7.3% of discontinuers (p<0.001). Among participants on monotherapy at baseline, continuation was greatest for angiotensin II type 1 receptor blocking agents (ARBs, 53.1%), angiotensin-converting enzyme inhibitors (44.4%) and β-blockers (41.8%). Only one quarter of participants treated with diuretic or calcium channel blockers at baseline remained so at follow-up. Conclusion: Antihypertensivedrug treatment is very stable in Switzerland. There are no big differences in persistence between antihypertensive classes, even if ARBs had the most favorable utilization pattern. Changes are only due to blood pressure level and improve blood pressure status.
