Time-dependent cognitive and somatic symptoms of depression as predictors of new cardiac-related events in at-risk patients: the UPBEAT-UK cohort.

BACKGROUND: Evidence suggests that somatic rather than cognitive depressive symptoms are risk factors for recurrent cardiac events in at-risk patients. However, this has never been explored using a time-dependent approach in a narrow time-frame, allowing a cardiac event-free time-window. METHODS: The analysis was performed on 595 participants [70.6% male, median age 72 (27-98)] drawn from the UPBEAT-UK heart disease patient cohort with 6-monthly follow-ups over 3 years. Depressive symptomatology was measured using the Patient Health Questionnaire-9 (PHQ-9) (four somatic, five cognitive items). New cardiac events (NCEs) including cardiac-related mortality were identified by expert examination of patient records. Analyses were performed using Cox proportional hazard models with delayed entry, with time-dependent depressive dimensions and covariates measured 12-18 months (median: 14.1, IQR: 3.5) prior to the event, with a 12-month cardiac event-free gap. RESULTS: There were 95 NCEs during the follow-up [median time-to-event from baseline: 22.3 months (IQR: 13.4)]. Both the somatic (HR 1.12, 95% CI 1.05-1.20, p = 0.001) and cognitive dimensions (HR 1.11, 95% CI 1.03-1.18, p = 0.004) were time-dependent risk factors for an NCE in the multi-adjusted models. Specific symptoms (poor appetite/overeating for the somatic dimension, hopelessness and feeling like a failure for the cognitive dimension) were also significantly associated. CONCLUSION: This is the first study of the association between depressive symptom dimensions and NCEs in at-risk patients using a time-to-event standardised approach. Both dimensions considered apart were independent predictors of an NCE, along with specific items, suggesting regular assessments and tailored interventions targeting specific depressive symptoms may help to prevent NCEs in at-risk populations.

Clinicians' attitudes to depression in Europe: a pooled analysis of Depression Attitude Questionnaire findings.

BACKGROUND: Depression in primary care is common but under-recognized and suboptimally managed. Health professionals' attitudes are likely to play an important part in their recognition and management of depression. OBJECTIVES: To pool findings from studies using the Depression Attitude Questionnaire (DAQ) to provide greater detail of clinicians' attitudes and the measure's psychometric properties. METHODS: Electronic databases and grey literature were searched for relevant studies. Data from eligible studies were requested and pooled analysis conducted. RESULTS: Twenty studies were eligible and data were obtained from 12 of these involving GPs (n = 1543) and nurses (n = 984). Responses showed strong disagreement that depression is due to ageing or weakness. European GPs were more positive about depression treatments than UK GPs; nurses were more favourable about psychotherapy than GPs. UK GPs especially strongly opposed notions that depression is best managed by psychiatrists. Trends over time indicated increasing acknowledgement of psychological therapies and the nurse's role in depression management. Factor analysis indicated that many DAQ items fitted weakly within an overall model. The most parsimonious solution involved two factors: a positive view of depression and its treatment response and professional confidence in depression management. CONCLUSIONS: Individual DAQ items appear to measure key aspects of clinicians' attitudes to depression, and item responses indicate important differences between professions and geographical settings as well as changes over time. There are problems with the DAQ as a scale: its internal consistency is weak, and several items appear specific to particular professions or service structures, indicating that this questionnaire should be revised.

Estimating probability of sustained recovery from mild to moderate depression in primary care: evidence from the THREAD study.

BACKGROUND: It is important for doctors and patients to know what factors help recovery from depression. Our objectives were to predict the probability of sustained recovery for patients presenting with mild to moderate depression in primary care and to devise a means of estimating this probability on an individual basis. METHOD: Participants in a randomized controlled trial were identified through general practitioners (GPs) around three academic centres in England. Participants were aged >18 years, with Hamilton Depression Rating Scale (HAMD) scores 12-19 inclusive, and at least one physical symptom on the Bradford Somatic Inventory (BSI). Baseline assessments included demographics, treatment preference, life events and difficulties and health and social care use. The outcome was sustained recovery, defined as HAMD score <8 at both 12 and 26 week follow-up. We produced a predictive model of outcome using logistic regression clustered by GP and created a probability tree to demonstrate estimated probability of recovery at the individual level. RESULTS: Of 220 participants, 74% provided HAMD scores at 12 and 26 weeks. A total of 39 (24%) achieved sustained recovery, associated with being female, married/cohabiting, having a low BSI score and receiving preferred treatment. A linear predictor gives individual probabilities for sustained recovery given specific characteristics and probability trees illustrate the range of probabilities and their uncertainties for some important combinations of factors. CONCLUSIONS: Sustained recovery from mild to moderate depression in primary care appears more likely for women, people who are married or cohabiting, have few somatic symptoms and receive their preferred treatment.

Evidence-based guidelines for treating depressive disorders with antidepressants: a revision of the 2000 British Association for Psychopharmacology guidelines.

A revision of the 2000 British Association for Psychopharmacology evidence-based guidelines for treating depressive disorders with antidepressants was undertaken to incorporate new evidence and to update the recommendations where appropriate. A consensus meeting involving experts in depressive disorders and their management was held in May 2006. Key areas in treating depression were reviewed, and the strength of evidence and clinical implications were considered. The guidelines were drawn up after extensive feedback from participants and interested parties. A literature review is provided, which identifies the quality of evidence to inform the recommendations, the strength of which are based on the level of evidence. These guidelines cover the nature and detection of depressive disorders, acute treatment with antidepressant drugs, choice of drug versus alternative treatment, practical issues in prescribing and management, next-step treatment, relapse prevention, treatment of relapse, and stopping treatment.

The Defeat Depression Campaign: psychiatry in the public arena.

OBJECTIVE: The adequate recognition and treatment of depression are inhibited by negative public attitudes and gaps in professional expertise. This paper describes the activities and efforts of the Defeat Depression Campaign, a joint activity of the Royal College of Psychiatrists and the Royal College of General Practitioners, in the United Kingdom. METHOD: A 5-year campaign was undertaken from 1992 to 1996, aimed at enhancing public awareness and attitudes and providing professional education. RESULTS: An informational media campaign directed toward the general public was successfully undertaken. Leaflets, books, and audiotapes were also prepared and distributed to the public. Multiprofessional conferences on specific aspects of depression were organized. An extensive program of general practice education included consensus conferences and statements, recognition and management guidelines, training videotapes, and other publications. Public attitudes were found to be relatively favorable, except attitudes toward antidepressants, which were viewed as addictive. A general consequence of the campaign was the development of much additional public material and professional education not directly originating from the campaign. Aspects of the campaign are being evaluated, including public attitude change, impact of educational materials on general practitioners, and prescription of antidepressants. CONCLUSIONS: A campaign of this kind serves a useful function in enhancing public education and awareness and improving professional recognition and management of depression.

Depression in the community: physician and patient perspective.

Depression and anxiety are the most common mental disorders seen by primary care physicians. The conditions often coexist. It has been reported that about half the psychiatric comorbidity in patients visiting their primary care physician goes unrecognized. Consequently, there is widespread agreement that an improvement in recognition of mental illnesses is required. This review examines how patient characteristics and patient presentation affect the acknowledgment of depression. Furthermore, the role of the physician will be discussed, with relation to the importance of acquiring specific consulting and prescribing skills for dealing with patients with depression. It is hoped that, with increasing awareness of depression and the development of training schemes for primary care physicians that focus specifically on the recognition and management of the condition in this setting, underrecognition and undertreatment of the disorder will improve.

Depression in Europe: experience from the DEPRES II survey. Depression Research in European Society.

Despite being one of the most prevalent psychiatric conditions in the community, depression is commonly unrecognised in clinical practice. The Depression Research in European Society (DEPRES) survey examined depression in a pan-European population (N=78463) and identified a 6-month prevalence of depression of 17%. In DEPRES II (N=1884), more than 50% of the individuals were categorised as being currently depressed, with one-third receiving antidepressant treatment. Cluster analysis grouped patients within six clearly differentiated types. Individuals with patient type 'severe depression and anxiety' (Group III), had the greatest number of symptoms and were more likely to be taking antidepressants than the other patient groups. In Group III, depression prevented individuals from undertaking normal activities for 6 weeks and prevented them from working for 1 month. The patient type making the most demands on healthcare resources are those with depression and anxiety. Prompt and effective treatment would be of benefit to all patient types, and the use of a selective serotonin reuptake inhibitor (SSRI) with activity against anxiety symptoms is an appropriate management strategy.

Depression in the community: the first pan-European study DEPRES (Depression Research in European Society).

DEPRESS (Depression Research in European Society) is the first large pan-European survey of depression in the community. A total of 13359 of the 78463 adults who participated in screening interviews across six countries were identified as suffering from depression, a 6-month prevalence of 17%. Major depression accounted for 6.9% of the cases of depression and minor depression for 1.8%. Depressed subjects in both these categories perceived that their working or social lives were substantially impaired by depressive symptoms. The remaining 8.3% of depressed subjects considered that their functional impairment was not substantial. A significant proportion of sufferers from depression (43%) failed to seek treatment for their depressive symptoms. Of those who did seek help (57%), most consulted a primary care physician, the frequency of consultation increasing with the severity of depression. Sufferers from major depression imposed the greatest demand on healthcare resources, making almost three times as many visits to their GP or family doctor as non-sufferers (4.4 vs 1.5 visits over 6 months). More than two-thirds of depressed subjects (69%) were not prescribed any treatment and when drug therapy was prescribed (31%), only 25% of these subjects were given antidepressant drugs. The number of days of work lost due to illness increased with the severity of depression. Major depression had most impact on productive work, with sufferers losing four times as many working days over 6 months as non-sufferers. The results of the DEPRES survey confirm the high prevalence of depression in the community and the burden imposed on the individual sufferer in terms of impaired quality of life and on society in terms of healthcare utilization and lost productivity.

DEPRES II (Depression Research in European Society II): a patient survey of the symptoms, disability and current management of depression in the community. DEPRES Steering Committee.

The first pan-European survey of depression in the community (DEPRES I) demonstrated that 17% of the general population suffer from depression (major depression, minor depression, or depressive symptoms). This article describes findings from a second phase of DEPRES (DEPRES II), in which detailed interviews based on a semi-structured questionnaire (78 questions) were conducted with 1884 DEPRES I participants who had suffered from depression and who consulted a healthcare professional about their symptoms during the previous 6 months. The mean time from onset of depression was 45 months, and the most commonly experienced symptoms during the latest period were low mood (76%), tiredness (73%) and sleep problems (63%). During the previous 6 months, respondents had been unable to undertake normal activities because of their depression for a mean of 30 days, and a mean of 20 days of work had been lost to depression by those in paid employment. Approximately one-third of respondents (30%) had received an antidepressant during the latest period of depression. Significantly more respondents given a selective serotonin reputake inhibitor found that their treatment made them feel more like their normal self than those given a tricyclic antidepressant, and fewer reported treatment-related concentration lapses, weight problems, and heavy-headedness (all P < 0.05). Approximately two-thirds of respondents (70%) had received no antidepressant therapy during the latest period of depression, and prescription of benzodiazepines alone, which are not effective against depression, was widespread (17%). There is a need for education of healthcare professionals to encourage appropriate treatment of depression.

Identification of depressed patient types in the community and their treatment needs: findings from the DEPRES II (Depression Research in European Society II) survey. DEPRES Steering Committee.

DEPRES II (Depression Research in European Society II), the first in-depth, pan-European survey of depression in the community, provided an opportunity to identify depressed patient types and their treatment needs. Cluster analysis applied to data generated from DEPRES II interviews revealed six depressed patient types with clearly differentiated profiles. The patient type with moderately impaired depression has episodic depression and minimal disability. By contrast, severe depression associated with anxiety presents with chronic symptoms, including anxiety and panic, and causes considerable disruption to normal life and employment. Depression associated with chronic physical problems and depression associated with social problems are characterized by chronic physical illness and relationship or financial difficulties, respectively, and sufferers are pessimistic about recovery. Depression associated with sleep problems is associated with symptoms of tiredness and broken or inadequate sleep, and is commonly caused by stress. Tiredness is also a principal symptom of depression associated with tiredness or fatigue, but sufferers' ability to sleep is unaffected. All patient types would benefit from antidepressant therapy. The depressed patient types identified from the DEPRES II data make intuitive sense, but now need to be tested for face validity in the primary care setting.

A randomized, double-blind, multi-centre, parallel-group study comparing the tolerability and efficacy of moclobemide and dothiepin hydrochloride in depressed patients in general practice.

A randomized, double-blind, multi-centre, parallel-group study compared the tolerability and efficacy of 450 mg of moclobemide and 75-150 mg of dothiepin in the management of depressed patients in general practice. Patients who fulfilled the DSM-III-R criteria for major depressive disorder and who scored 13 or more on the Hamilton Depression Rating Scale were admitted. The trial lasted six weeks. The dose of moclobemide was 150 mg three times daily and that of dothiepin was 75 mg daily for the first two weeks and 150 mg thereafter. Assessments were made at baseline and after one, three and six weeks using the HDRS, the Zung SRS and the CGI. Adverse events and vital signs were monitored at each visit, and laboratory screening tests performed at the beginning and end of the study. Sixty-four general practitioners from four centres recruited 345 patients: 175 received dothiepin and 170 moclobemide; 265 completed six weeks of treatment. Thirty-eight dothiepin-treated patients (22%) and 42 who received moclobemide (25%) dropped out, most commonly because they experienced adverse events. More patients on dothiepin (24) than on moclobemide (16) dropped out for this reason; the incidence of adverse events was 10% higher in the dothiepin-treated group and of "side effects" more than 10% higher, the latter difference being statistically significant. Both treatments resulted in significant improvement; this was greater in the dothiepin-treated group and the difference was statistically significant, although clinically small.

Symptom attribution and the recognition of psychiatric morbidity.

OBJECTIVE: Patients' interpretation of ambiguous physical symptoms may influence illness presentation in primary care. The present study sought to investigate the influence of symptom attribution style on the recognition of psychiatric morbidity by general practitioners (GPs). METHODS: Patients consulting GPs completed assessments of attribution style and General Health Questionnaires (GHQs), while GPs provided independent ratings of psychiatric distress. Analysis examined the relationship between patient demographic variables, attribution style (using the Symptom Interpretation Questionnaire [SIQ]), and GP and GHQ assessments of patients' mental health. RESULTS: The results indicate that severity of disorder and patient age were reliable predictors of recognition: normalizing and psychological attributions were additional predictors in some analyses, but their effects were inconsistent. CONCLUSIONS: The results provide some support for the role of symptom attribution in the recognition of psychiatric morbidity, but suggest that the predictive value of such attributions may be relatively modest. The SIQ may not be the optimum instrument for the measurement of attributions.

Continuing medical education in mental illness: a paradox for general practitioners.

BACKGROUND: In 1992, the Royal College of General Practitioners instituted its fellowship in mental health education, which aimed to provide general practitioner tutors with the skills they need to help general practitioners manage mental illness in general practice. However, the emphasis of the fellowship on pedagogic education may discourage educators wishing to introduce andragogic teaching, a paradox which general practitioners must resolve if the aims are to be realized. AIM: This study set out to follow the difficulties encountered by the regional fellows in managing the fellowship and to understand how the scheme has evolved. METHOD: Data collected for interim evaluation of the fellowship was studied and interviews undertaken with the senior fellow and the regional fellows participating in the scheme. RESULTS: From its beginnings, the project encountered difficulties involving acceptance among general practitioner tutors. In response to the objections raised, the project metamorphosed through three stages, from a (perceived) pedagogic approach to a much more overtly learner-centered one. CONCLUSION: Learner-centred education requires trust and belief in the ability of general practitioners to teach general practitioners; over-protection of the audience from 'non-expert' educators merely perpetuates the status quo. If education in mental health care is to become truly learner-centred, general practitioners must address this paradox.

Why do general practitioners recognize major depression in one woman patient yet miss it in another?

The aim of this study was to establish whether psychiatric patient characteristics and the presence of physical illness affected general practitioners' recognition of major depressive illness in women patients. The 30-item general health questionnaire was used as a first stage screening instrument for psychiatric morbidity and each patient selected was interviewed, usually within three days of consulting their general practitioner, using the combined clinical interview. A sample of 72 women with major depressive disorder was obtained from patients consulting 36 general practitioners mainly from the south west Thames region of England, each general practitioner providing one patient he or she had correctly recognized as being depressed and one patient whose depression had not been recognized. Few differences were found between the groups with recognized and unrecognized depression in their psychiatric or physical features. More patients with unrecognized depression experienced physical illness and were tired. Patients with serious physical disease were five times more likely not to be recognized as depressed than those without physical disease. Patients with recognized depression described a more distinct quality to their depressed mood. Women with unrecognized major depression are similar to those women whose major depression is recognized by their general practitioner. These findings require further elaboration by process and content analysis of the women's consultations.

How does the content of consultations affect the recognition by general practitioners of major depression in women?

BACKGROUND: Major depression is a common and disabling condition. However, for many reasons, the condition is not recognized in about half of the patients with major depression. AIM: The aim of the study was to establish whether the content of general practice consultations affected general practitioners' recognition of major depressive illness in women patients. METHOD: The 30-item general health questionnaire was used as a first stage screening instrument for psychiatric morbidity. Patients newly recognized as depressed by their general practitioner and those not recognized as depressed who scored 11 or more on the questionnaire were interviewed, usually within three days of consulting their general practitioner, using the combined psychiatric interview. Videorecordings of the consultations for these two groups of women were analysed; analyses were based on mentions of physical, psychiatric and social symptoms and on whether the first mention of a psychiatric symptom was within the first four mentions of any symptoms (early in the consultation) or after four mentions of any symptoms (late) or if psychiatric symptoms were not mentioned. RESULTS: A paired sample of 72 women with major depression was obtained from patients consulting 36 general practitioners, each general practitioner providing one patient whom he or she had correctly recognized as being depressed and one patient whose depression had not been recognized. Women with major depression were about five times more likely to have their depression recognized if they mentioned their psychiatric symptoms early in the consultation compared with those who either left it later to mention such symptoms or never mentioned them. Major depression was more likely to be recognized if no physical illness was present. After adjusting for physical illness, depression was 10 times less likely to be recognized if the first psychiatric symptom was mentioned late in the consultation, or not mentioned at all, than if it was mentioned early in the consultation. CONCLUSION: General practitioners need to remember that patients who present with symptoms of physical illness may also have depression. They also need to remember to give equal importance diagnostically to mentions of symptoms at whatever point they occur in the consultation, regardless of the presence or absence of physical illness.

Impact of a national campaign on GP education: an evaluation of the Defeat Depression Campaign.

BACKGROUND: The Defeat Depression Campaign, which was run by the Royal College of Psychiatrists and the Royal College of General Practitioners (RCGP) from 1992 to 1996, aimed to educate general practitioners (GPs) to recognize and manage depression. AIM: To measure the educational impact on GPs of the Defeat Depression Campaign. METHOD: A postal survey using a structured questionnaire was distributed to 2046 GPs obtained by systematically sampling 1 in 14 GPs from alphabetical lists from family health services authorities (FHSAs) in England and Wales. The questionnaire covered awareness of the campaign, awareness and use of campaign materials, and ratings of the usefulness of the campaign in relation to other educational activities. RESULTS: Two-thirds of GPs were aware of the campaign and 40% had definitely or possibly made changes in practice as a result of it. Impact of materials was highest for a consensus statement on the recognition and management of depression in general practice and for guidelines derived from it, each of which had been read in detail by about one quarter of responders and was known of by an additional one third. Impact was low for the other materials. The campaign had the highest impact among younger GPs, members of the RCGP, and (less strongly) among those who had undertaken a six-month post in psychiatry, those who were working in larger practices and fundholding practices, and women; 56% of GPs had attended a teaching session on depression in the past three years. CONCLUSION: A national campaign of this kind can have a useful impact, but it needs to be supplemented by local and practice-based teaching activities.

Lay people's attitudes to treatment of depression: results of opinion poll for Defeat Depression Campaign just before its launch.

OBJECTIVE: To investigate the attitudes of the general public towards depression before the Defeat Depression Campaign of the Royal Colleges of Psychiatrists and General Practitioners; these results form the baseline to assess the change in attitudes brought about by the campaign. DESIGN: Group discussions generated data for initial qualitative research. The quantitative survey comprised a doorstep survey of 2003 people in 143 places around the United Kingdom. RESULTS: The lay public in general seemed to be sympathetic to those with depression but reluctant to consult. Most (1704 (85%)) believed counselling to be effective but were against antidepressants. Many subjects (1563 (78%)) regarded antidepressants as addictive. CONCLUSIONS: Although people are sympathetic towards those with depression, they may project their prejudices about depression on to the medical profession. Doctors have an important role in educating the public about depression and the rationale for antidepressant treatment. In particular, patients should know that dependence is not a problem with antidepressants.

Positive psychology: an approach to supporting recovery in mental illness.

This paper reviews the literature on positive psychology with a special focus on people with mental illness. It describes the characteristics, critiques, and roots of positive psychology and positive psychotherapy, and summarises the existing evidence on positive psychotherapy. Positive psychology aims to refocus psychological research and practice on the positive aspects of experience, strengths, and resources. Despite a number of conceptual and applied research challenges, the field has rapidly developed since its introduction at the turn of the century. Today positive psychology serves as an umbrella term to accommodate research investigating positive emotions and other positive aspects such as creativity, optimism, resilience, empathy, compassion, humour, and life satisfaction. Positive psychotherapy is a therapeutic intervention that evolved from this research. It shows promising results for reducing depression and increasing well-being in healthy people and those with depression. Positive psychology and positive psychotherapy are increasingly being applied in mental health settings, but research evidence involving people with severe mental illness is still scarce. The focus on strengths and resources in positive psychology and positive psychotherapy may be a promising way to support recovery in people with mental illness, such as depression, substance abuse disorders, and psychosis. More research is needed to adapt and establish these approaches and provide an evidence base for their application.

A conceptual framework for improving well-being in people with a diagnosis of psychosis.

Background. Well-being is important for people with severe mental illness, such as psychosis. So far, no clear concept of well-being exists for this client group. A recent systematic review and narrative synthesis developed a static framework of well-being components. The present study aims to validate the static framework and to illuminate the processes by which well-being is experienced by people with psychosis. Methods. Semi-structured interviews were conducted with 23 service users with psychosis exploring their experience of well-being. Thematic analysis was used to analyse the data employing techniques taken from grounded theory to enhance the rigour of the analysis. Respondent validation was undertaken with 13 of the 23 participants. Results. Three superordinate categories of well-being were identified: current sense of self; transition to enhanced sense of self and enhanced sense of self. In the dynamic process of improving well-being the current sense of self undergoes a transition to an enhanced sense of self. The four factors influencing the transition are consistent with the static framework of well-being, hence validating the static framework. In addition, we identified three determinants of current sense of self and seven indicators of enhanced sense of self, which represent the achievement of improved well-being. Conclusions. This study provides an empirically defensible framework for understanding well-being in terms of determinants, influences and indicators. The influences are targets for interventions to improve well-being, and the indicators are outcome domains to assess the effectiveness of services in supporting well-being.

Presence and predictors of pain in depression: results from the FINDER study.

BACKGROUND: Patients with depression often experience pain. There is limited understanding of the relation between pain and other symptoms (depressive, anxious and non-painful somatic symptoms). This exploratory study assesses pain severity and interference of pain with functioning in a clinically depressed population and investigates the relation between the different groups of symptoms. METHODS: FINDER was a 6-month prospective, observational study investigating health-related quality of life of outpatients with depression initiating antidepressant treatment. Patients completed ratings on the Hospital Anxiety and Depression Scale (HADS), Somatic Symptom Inventory (SSI-28), and overall pain severity and interference of pain with functioning using Visual Analogue Scales (VAS) at baseline and at 3 and 6 months. Regression analyses identified factors associated with overall pain severity and interference of pain with functioning, at baseline and over the observation period. RESULTS: Of 3468 eligible patients at baseline, 56.3% experienced moderate to severe pain and 53.6% had moderate to severe pain-related interference with functioning. At 6 months of follow-up, these proportions decreased to 32.5% and 28.1%, respectively. Higher baseline SSI-somatic scores (non-painful) were strongly associated with greater pain severity and greater pain-related interference with functioning at baseline and over 6 months. Certain socio-demographic (increasing age, being unemployed) and depression-related factors (more previous episodes, longer duration of current episode) were also significantly associated with greater pain severity and interference over 6 months, while higher baseline severity of depression (HADS-D) and further education were associated with less severe pain or pain-related interference with functioning over 6 months. CONCLUSIONS: Over half of depressed patients in this study experienced moderate to severe pain. Painful somatic symptoms appear to be closely related to non-painful somatic symptoms, more than to depressive or anxious symptoms suggesting that painful and non-painful somatic symptoms can be considered as one group of 'somatic symptoms,' all of them associated with depressive and anxious symptoms.
