Factors Influencing Depression Endpoints Research (FINDER): Baseline results of Italian patients with depression

Luigi Grassi — 2009-05-29T00:00:00Z

Background: Factors Influencing Depression Endpoints Research (FINDER) is a 6-month, prospective, observational study carried out in 12 European countries aimed at investigating health-related quality of life (HRQoL) in outpatients receiving pharmacological treatment for a first or new depressive episode. Baseline characteristics of patients enrolled in Italy are presented. Methods: All treatment decisions were at the discretion of the investigator. Data were collected at baseline and after 3 and 6 months of treatment. Baseline evaluations included demographics, medical and psychiatric history, and medications used in the last 24 months and prescribed at enrolment. The Hospital Anxiety and Depression Scale (HADS), was adopted to evaluate depressive symptoms, while somatic and painful physical symptoms were assessed by using the Somatic Symptom Inventory (SSI) and a 0 to 100 mm visual analogue scale (VAS), HRQoL via 36-item Short Form Health Survey (SF-36), and the European Quality of Life 5-Dimensions (EQ-5D) instrument. Results: A total of 513 patients were recruited across 38 sites. The mean ± standard deviation (SD) age at first depressive episode was 38.7 ± 15.9 years, the mean duration of depression 10.6 ± 12.3 years. The most common psychiatric comorbidities in the previous 24 months were anxiety/panic (72.6%) and obsessive/compulsive disorders (13.4%), while 35.9% had functional somatic syndromes. Most patients (65.1%) reported pain from any cause. Monotherapy with selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) was prescribed at enrolment in 64.5% and 6.4% of the cases, respectively. The most commonly prescribed agents were sertraline (17.3%), escitalopram (16.2%), venlaflaxine (15.6%) and paroxetine (14.8%). The mean HADS subscores for depression and anxiety were 13.3 ± 4.2 and 12.2 ± 3.9, respectively; 76.4% of patients could be defined as being 'probable cases' for depression and 66.2% for anxiety. The mean total score of VAS-pain in the last week was 42.9 ± 27.1, with highest scores reported in the 'interference of pain with daily activities' and in 'amount of time patient was awake and had pain'. From SF-36, the worst health status was found for role limitations due to emotional problem, mental health and social functioning. A mean score < 50 (that is, below the standardised population norm) was also found in all remaining domains. The SF-36 summary scores and EQ-5D (health status and VAS) were lower in patients with moderate/severe pain than in those with no or mild pain. Conclusion: The baseline results of patients enrolled in the FINDER study in Italy show clinical and functional impairments, and poor HRQoL. The results obtained after 6 months of therapy will permit better understanding the effects of different variables on clinical outcomes and HRQoL.

Obsessive-compulsive disorder and related disorders: a comprehensive survey

Michele Fornaro — 2009-05-18T00:00:00Z

Our aim was to present a comprehensive, updated survey on obsessive-compulsive disorder (OCD) and obsessive-compulsive related disorders (OCRDs) and their clinical management via literature review, critical analysis and synthesis.Information on OCD and OCRD current nosography, clinical phenomenology and etiology, may lead to a better comprehension of their management. Clinicians should become familiar with the broad spectrum of OCD disorders, since it is a pivotal issue in current clinical psychiatry.

Schizophrenia pathophysiology: are we any closer to a complete model?

Shaheen Lakhan — 2009-05-15T00:00:00Z

Schizophrenia, a severe brain disorder that involves hallucinations, disordered thinking and deficiencies in cognition, has been studied for decades in order to determine the early events that lead to this neurological disorder. In this review, we interpret the developmental and genetic models that have been proposed and treatment options associated with these models.Schizophrenia was initially thought to be hereditary based on studies of high incidence in certain families. Additionally, studies on specific genes such as ZDHHC8 and DTNBP1 seem to suggest susceptibility to the onset of this disorder. However, no single gene variation has been linked to schizophrenia, and recent evidence on sporadic cases of schizophrenia refutes genetics as being a singular cause of the disease. In addition, current data suggests neurodevelopmental or environmental causes such as viral infections and prenatal/perinatal complications.Before any brain disorder can be understood, however, multiple cognitive neuroscientific models that accommodate evidence from many biomedical research fields should be considered, and unfortunately, many of these models are in the earliest stages of development. Consequently, it makes us question whether we are any closer to an adequate understanding of the pathophysiology of schizophrenia.

The Alcohol Use Disorders Identification Test (AUDIT): reliability and validity of the Greek version

George Moussas — 2009-05-14T00:00:00Z

Background: Problems associated with alcohol abuse are recognised by the World Health Organization as a major health issue, which according to most recent estimations is responsible for 1.4% of the total world burden of morbidity and has been proven to increase mortality risk by 50%. Because of the size and severity of the problem, early detection is very important. This requires easy to use and specific tools. One of these is the Alcohol Use Disorders Identification Test (AUDIT).AimThis study aims to standardise the questionnaire in a Greek population. Methods: AUDIT was translated and back-translated from its original language by two English-speaking psychiatrists. The tool contains 10 questions. A score ≥ 11 is an indication of serious abuse/dependence. In the study, 218 subjects took part: 128 were males and 90 females. The average age was 40.71 years (± 11.34). From the 218 individuals, 109 (75 male, 34 female) fulfilled the criteria for alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), and presented requesting admission; 109 subjects (53 male, 56 female) were healthy controls. Results: Internal reliability (Cronbach α) was 0.80 for the controls and 0.80 for the alcohol-dependent individuals. Controls had significantly lower average scores (t test P < 0.001) when compared to the alcoholics. The questionnaire's sensitivity for scores >8 was 0.98 and its specificity was 0.94 for the same score. For the alcohol-dependent sample 3% scored as false negatives and from the control group 1.8% scored false positives. In the alcohol-dependent sample there was no difference between males and females in their average scores (t test P > 0.05). Conclusion: The Greek version of AUDIT has increased internal reliability and validity. It detects 97% of the alcohol-dependent individuals and has a high sensitivity and specificity. AUDIT is easy to use, quick and reliable and can be very useful in detection alcohol problems in sensitive populations.

A short review on the aetiology and pathophysiology of alcoholism

George Moussas — 2009-05-14T00:00:00Z

Alcoholism is a chronic remitting and relapsing condition; its aetiology and pathophysiology remains largely obscure despite recent advances. This review summarises the current knowledge about the causation (biological or psychological) of alcohol addiction. This involves heredity, candidate genes, alcohol metabolism regulation and the influence of alcohol in the pathophysiology of the different neurotransmitter systems. Alcohol addiction is a multifactorial phenomenon where personality structure, individual state of mind and social influences are in constant interaction with brain neurobiology and pathophysiology. This disorder influences different sexes in different ways and causes major problems, especially in developed societies.

The Inventory of Personality Organisation: its psychometric properties among student and clinical populations in Japan

Hiromi Igarashi — 2009-05-06T00:00:00Z

Background: The Inventory of Personality Organisation (IPO) is a self-report measure that reflects personality traits, as theorised by Kernberg. Methods: In study 1, the Japanese version of the IPO was distributed to a population of Japanese university students (N = 701). The students were randomly divided into two groups. The factor structure derived from an exploratory factor analysis among one subsample was tested using a confirmatory factor structure among another subsample. In study 2, the factor-driven subscales of the IPO were correlated with other variables that would function as external criteria to validate the scale in a combined population of the students used in study 1 and psychiatric outpatients (N = 177). Results: In study 1 the five-factor structure presented by the original authors was replicated in exploratory factor analyses in one subgroup of students. However, this was through reduction of the number of items (the number of the primary items was reduced from 57 to 24 whereas the number of the additional items was reduced from 26 to 13) due to low endorsement frequencies as well as low factor loadings on a designated factor. The new factor structure was endorsed by a confirmatory factor analysis in the other student subgroup. In study 2 the new five subscales of the Japanese IPO were likely to be correlated with younger age, more personality psychopathology (borderline and narcissistic), more dysphoric mood, less psychological well-being, more insecure adult attachment style, lower self-efficacy, and more frequent history of childhood adversity. The IPO scores were found to predict the increase in suicidal ideation in a week's time in a longitudinal follow-up. Conclusion: Although losing more than 40% of the original items, the Japanese IPO may be a reliable and valid measure of Kernberg's personality organisation for Japanese populations.

Well-being of medical students and their awareness on substance misuse: a cross-sectional survey in Pakistan

Abdul Wahab Yousafzai — 2009-02-19T00:00:00Z

ObjectiveTo investigate psychological well-being and substance abuse among medical students in Pakistan. Methods: A cross-sectional questionnaire-based survey was conducted in six medical colleges across Pakistan. Final-year medical students were interviewed by either a postgraduate trainee in psychiatry or a consultant psychiatrist. Results: A total of 540 medical students were approached; 342 participated and the response rate was 64.5%. Mean age was 23.73 years (SD 2.45 years); 52.5% were male and 90% single. Two out of every five respondents reported that work/study at medical school affected their personal health and well-being. A considerable proportion of students were aware of alcohol and smoking as coping strategies for stress in medical students. The main factors causing stress were heavy workload (47.4%), relationship with colleagues (13.5%) and staff (11.9%). A total of 30% reported a history of depression and 15% among them had used an antidepressant. More than half were aware of depression in colleagues. The majority of respondents said that teaching provided on substance misuse in the areas of alcohol and illegal drugs, management/treatment of addiction, and models of addiction was poor. There was significant association (p = 0.044) between stress and awareness about alcohol as a coping strategy for stress among medical students. A significant negative association was also found between medical colleges in public sector (p = 0.052), female gender (p = 0.003) and well-being. Conclusion: The majority of the medical students reported a negative impact of heavy workload on their psychological well-being. Significant numbers of medical students think that substance misuse is a coping strategy for stress. Teaching on addiction/addictive substances is poor at undergraduate level in Pakistani medical colleges.

The relationship between antipsychotic medication adherence and patient outcomes among individuals diagnosed with bipolar disorder: a retrospective study

Maureen Lage — 2009-02-18T00:00:00Z

Background: Reducing hospitalizations and emergency room visits is important to improve patient outcomes. This observational study examined the association between adherence to antipsychotics and risk of hospitalizations and emergency room (ER) visits among patients with bipolar disorder. Methods: Claims data from commercial healthcare plans (Pharmetrics; January 2000 to December 2006) for patients with bipolar disorder receiving an antipsychotic prescription were examined. Adherence was analyzed over a 12-month follow-up period after the receipt of first prescription of an antipsychotic. Adherence to antipsychotics was measured by the medication possession ratio (MPR). The MPR was calculated as the number of days that an antipsychotic medication was filled as compared with the total number of days during the follow-up period. Logistic stepwise regressions examined the association between achievement of various adherence goals and patient outcomes (hospitalization or ER visit for mental health or any reason). Results: In total, 7,769 patients with bipolar disorder were included. The mean MPR was 0.417, with 61.7% of individuals having an MPR < 0.50, and 78.7% an MPR < 0.75. As adherence improved, the risk of hospitalization or ER visit declined. A significant reduction in the risk of hospitalization (odds ratio (OR) 0.85, 95% confidence interval (CI) 0.75 to 0.98) or an ER visit (OR 0.84, 95% CI 0.74 to 0.96) for any cause was associated with an MPR ≥ 0.75. An MPR ≥ 0.80 was associated with a significant reduction in the risk of a mental health-related hospitalization (OR 0.82, 95% CI 0.70 to 0.95), while an MPR ≥ 0.90 was associated with a significant reduction in risk of a mental health-related ER visit (OR 0.71, 95% CI 0.54 to 0.91). Conclusion: Patients with lower antipsychotic adherence were at greater risk of hospitalizations and ER visits. Thus, any efforts to increase adherence, even in small increments, can be helpful in decreasing these risks.

Etiological explanation, treatability and preventability of childhood autism: a survey of Nigerian healthcare workers' opinion

Muideen Bakare — 2009-02-12T00:00:00Z

Background: Because of their peculiar sociocultural background, healthcare workers in sub-Saharan African subcultures may have various conceptions on different aspects of autism spectrum disorders (ASD), such as etiology, treatment and issues of prognosis. These various conceptions, if different from current knowledge in literature about ASD, may negatively influence help-seeking behavior of parents of children with ASD who seek advice and information from the healthcare workers. This study assessed the opinions of healthcare workers in Nigeria on aspects of etiology, treatability and preventability of childhood autism, and relates their opinions to the sociodemographic variables. Methods: Healthcare workers working in four tertiary healthcare facilities located in the south-east and south-south regions of Nigeria were interviewed with a sociodemographic questionnaire, personal opinion on etiology, treatability and preventability of childhood autism (POETPCA) questionnaire and knowledge about childhood autism among health workers (KCAHW) questionnaire to assess their knowledge and opinions on various aspects of childhood autism. Results: A total of 134 healthcare workers participated in the study. In all, 78 (58.2%), 19 (14.2%) and 36 (26.9%) of the healthcare workers were of the opinion that the etiology of childhood autism can be explained by natural, preternatural and supernatural causes, respectively. One (0.7%) of the healthcare workers was unsure of the explanation of the etiology. Knowledge about childhood autism as measured by scores on the KCAHW questionnaire was the only factor significantly associated with the opinions of the healthcare workers on etiology of childhood autism. In all, 73 (54.5%) and 43 (32.1%), of the healthcare workers subscribed to the opinion that childhood autism is treatable and preventable respectively. Previous involvement with managing children with ASD significantly influenced the opinion of the healthcare workers in subscribing to treatability of childhood autism, while working experience of less than 6 years among the healthcare workers significantly influenced the opinion of the healthcare workers in admitting to believing in the preventability of childhood autism. Conclusion: In designing policies and programs to change negative opinions or beliefs of healthcare workers about childhood autism, there is a need for baseline information such as this survey. Changing the negative opinions or beliefs of the healthcare workers about childhood autism should encourage appropriate help-seeking behavior among parents of children with ASD who may be seeking advice or information from the healthcare workers. This would encourage early interventions, which are essential to prognosis of childhood autism.
