Prevalence and correlates of depressive disorders in people with Type 2 diabetes: results from the International Prevalence and Treatment of Diabetes and Depression (INTERPRET-DD) study, a collaborative study carried out in 14 countries.

AIMS: To assess the prevalence and management of depressive disorders in people with Type 2 diabetes in different countries. METHODS: People with diabetes aged 18-65 years and treated in outpatient settings were recruited in 14 countries and underwent a psychiatric interview. Participants completed the Patient Health Questionnaire and the Problem Areas in Diabetes scale. Demographic and medical record data were collected. RESULTS: A total of 2783 people with Type 2 diabetes (45.3% men, mean duration of diabetes 8.8 years) participated. Overall, 10.6% were diagnosed with current major depressive disorder and 17.0% reported moderate to severe levels of depressive symptomatology (Patient Health Questionnaire scores >9). Multivariable analyses showed that, after controlling for country, current major depressive disorder was significantly associated with gender (women) (P<0.0001), a lower level of education (P<0.05), doing less exercise (P<0.01), higher levels of diabetes distress (P<0.0001) and a previous diagnosis of major depressive disorder (P<0.0001). The proportion of those with either current major depressive disorder or moderate to severe levels of depressive symptomatology who had a diagnosis or any treatment for their depression recorded in their medical records was extremely low and non-existent in many countries (0-29.6%). CONCLUSIONS: Our international study, the largest of this type ever undertaken, shows that people with diabetes frequently have depressive disorders and also significant levels of depressive symptoms. Our findings indicate that the identification and appropriate care for psychological and psychiatric problems is not the norm and suggest a lack of the comprehensive approach to diabetes management that is needed to improve clinical outcomes.

The cross-national epidemiology of specific phobia in the World Mental Health Surveys.

BACKGROUND: Although specific phobia is highly prevalent, associated with impairment, and an important risk factor for the development of other mental disorders, cross-national epidemiological data are scarce, especially from low- and middle-income countries. This paper presents epidemiological data from 22 low-, lower-middle-, upper-middle- and high-income countries. METHOD: Data came from 25 representative population-based surveys conducted in 22 countries (2001-2011) as part of the World Health Organization World Mental Health Surveys initiative (n = 124 902). The presence of specific phobia as defined by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition was evaluated using the World Health Organization Composite International Diagnostic Interview. RESULTS: The cross-national lifetime and 12-month prevalence rates of specific phobia were, respectively, 7.4% and 5.5%, being higher in females (9.8 and 7.7%) than in males (4.9% and 3.3%) and higher in high- and higher-middle-income countries than in low-/lower-middle-income countries. The median age of onset was young (8 years). Of the 12-month patients, 18.7% reported severe role impairment (13.3-21.9% across income groups) and 23.1% reported any treatment (9.6-30.1% across income groups). Lifetime co-morbidity was observed in 60.5% of those with lifetime specific phobia, with the onset of specific phobia preceding the other disorder in most cases (72.6%). Interestingly, rates of impairment, treatment use and co-morbidity increased with the number of fear subtypes. CONCLUSIONS: Specific phobia is common and associated with impairment in a considerable percentage of cases. Importantly, specific phobia often precedes the onset of other mental disorders, making it a possible early-life indicator of psychopathology vulnerability.

Mental disorders among college students in the World Health Organization World Mental Health Surveys.

BACKGROUND: Although mental disorders are significant predictors of educational attainment throughout the entire educational career, most research on mental disorders among students has focused on the primary and secondary school years. METHOD: The World Health Organization World Mental Health Surveys were used to examine the associations of mental disorders with college entry and attrition by comparing college students (n = 1572) and non-students in the same age range (18-22 years; n = 4178), including non-students who recently left college without graduating (n = 702) based on surveys in 21 countries (four low/lower-middle income, five upper-middle-income, one lower-middle or upper-middle at the times of two different surveys, and 11 high income). Lifetime and 12-month prevalence and age-of-onset of DSM-IV anxiety, mood, behavioral and substance disorders were assessed with the Composite International Diagnostic Interview (CIDI). RESULTS: One-fifth (20.3%) of college students had 12-month DSM-IV/CIDI disorders; 83.1% of these cases had pre-matriculation onsets. Disorders with pre-matriculation onsets were more important than those with post-matriculation onsets in predicting subsequent college attrition, with substance disorders and, among women, major depression the most important such disorders. Only 16.4% of students with 12-month disorders received any 12-month healthcare treatment for their mental disorders. CONCLUSIONS: Mental disorders are common among college students, have onsets that mostly occur prior to college entry, in the case of pre-matriculation disorders are associated with college attrition, and are typically untreated. Detection and effective treatment of these disorders early in the college career might reduce attrition and improve educational and psychosocial functioning.

Estimating the burden of early onset dementia; systematic review of disease prevalence.

Dementia is more common in older age but a number of people develop symptoms at a younger age and are said to have early onset dementia (EOD). Those with EOD face different challenges to those with onset later in life. It has been difficult to quantify this disease burden. This is a systematic review of papers reporting on the prevalence of EOD. A search of Medline and Embase was performed. This was followed by a hand search of the references of these papers. Eleven suitable studies were included. All of the data was from more economically developed countries. The studies were heterogeneous in their design hindering direct comparison. The majority of the papers looked at all types of dementia although many gave a breakdown of the prevalence of different subgroups. A variety of diagnostic criteria was employed. Figures of 38 to 260 per 100,000 are quoted by papers looking at various different types of dementia together with an onset of between 30 and 64 or up to 420 per 100,000 for those aged 55-64. Prevalence rises as age approaches 65. Epidemiological data for prevalence rates for EOD are sparse. EOD remains a rare condition with low case numbers. Assimilation and comparison of results from existing studies is difficult due to methodological heterogeneity. Cross-national standardization of methodology should be a priority for future research in this area.

Patient characteristics and symptoms associated with perceived coercion during hospital treatment.

OBJECTIVE: Large numbers of psychiatric patients either are involuntarily admitted to hospital treatment or feel coerced despite a legally voluntary admission. For ethical and clinical reasons, their perceived coercion should be reduced as far as possible. There is however limited evidence on patient characteristics associated with perceived coercion during hospital treatment. This study aimed to identify i) sociodemographic and clinical characteristics associated with perceived coercion at admission and ii) changes in symptoms and global functioning associated with changes in perceived coercion over time. METHOD: Three thousand and ninety three in-patients who were involuntarily admitted or felt coerced to hospital treatment despite a legally voluntary admission were recruited in the European evaluation of coercion in psychiatry and harmonization of best clinical practice - EUNOMIA project in 11 European countries. Perceived coercion, global functioning and symptoms were assessed after admission and at a 3-month follow-up. RESULTS: Involuntary admission, female gender, poorer global functioning and more positive symptoms were associated with higher levels of perceived coercion at admission. Perceived coercion significantly decreased over time, and the improvements in global functioning and positive symptoms were associated with reduction in perceived coercion. CONCLUSION: Female patients perceive more coercion in psychiatric hospital treatment. Effective treatment for positive symptoms and improving patients' global functioning may lead to a reduction in perceived coercion.

Mortality in people with mental disorders in Poland: A nationwide, register-based cohort study.

BACKGROUND: Mortality among people with mental disorders is higher in comparison with the general population. There is a scarcity of studies on mortality in the abovementioned group of people in Central and Eastern European countries. METHODS: The study aimed to assess all-cause mortality in people with mental disorders in Poland. We conducted a nationwide, register-based cohort study utilizing data from two nationwide registries in Poland: the registry of healthcare services reported to the National Health Fund (2009-2018) and the all-cause death registry from Statistics Poland (2019). We identified individuals who were consulted or hospitalized in public mental healthcare facilities and received at least one diagnosis of mental disorders (International Statistical Classification of Diseases and Health Problems [ICD-10]) from 2009 to 2018. Standardized mortality ratios (SMRs) were compared between people with a history of mental disorder and the general population. RESULTS: The study comprised 4,038,517 people. The SMR for individuals with any mental disorder compared with the general population was 1.54. SMRs varied across diagnostic groups, with the highest values for substance use disorders (3.04; 95% CI 3.00-3.09), schizophrenia, schizotypal and delusional disorders (2.12; 95% CI 2.06-2.18), and pervasive and specific developmental disorders (1.68; 95% CI 1.08-2.29). When only inpatients were considered, all-cause mortality risk was almost threefold higher than in the general population (SMR 2.90; 95% CI 2.86-2.94). CONCLUSIONS: In Poland, mortality in people with mental disorders is significantly higher than in the general population. The results provide a reference point for future longitudinal studies on mortality in Poland.

Epidemiological studies of cognitive impairment and dementia across Eastern and Middle European countries (epidemiology of dementia in Eastern and Middle European Countries).

OBJECTIVE: To determine the availability and the consistency of prevalence findings of epidemiological studies on cognitive impairment and dementia conducted in Eastern and Middle Europe. METHODS: We adopted a stepwise multimethod study approach consisting of iterative literature searches for epidemiological articles published between 1990 and 2006 and subsequent data analyses of published material, reanalyses of existing accessible epidemiological data sets and expert inquiries in Eastern and Middle European countries. Systematic computer-assisted searches used the keywords: "dementia", "Alzheimer", "cognitive impairment", "incidence", "prevalence", "epidemiology" in combination with the name of the relevant countries or "Europe" in English and Polish language. We supplemented the literature search with a review of the references in the articles that were identified during the initial search. RESULTS: We were able to find few regional and country-specific epidemiological studies of various kinds (population-based, cohort, cross-sectional studies) and conducted on different restricted population groups of patients (from neurological units, out-patients units, residential homes). No studies were identified from most of the countries taken under consideration and the ones we found were characterized by an immense diversity with a considerable degree of clinical and methodological variations. The few studies that there are suggest prevalence rates of dementia in Eastern Europe similar to those in Western Europe. CONCLUSIONS: There is strong need for epidemiological studies in Eastern and Middle Europe, as well as for greater coordination and standardization of methods to improve the quality and comparability of epidemiological data to determine the prevalences' rates of dementia in all the EU countries.

Factors associated with the onset of major depressive disorder in adults with type 2 diabetes living in 12 different countries: results from the INTERPRET-DD prospective study.

AIMS: To examine the factors that are associated with changes in depression in people with type 2 diabetes living in 12 different countries. METHODS: People with type 2 diabetes treated in out-patient settings aged 18-65 years underwent a psychiatric assessment to diagnose major depressive disorder (MDD) at baseline and follow-up. At both time points, participants completed the Patient Health Questionnaire (PHQ-9), the WHO five-item Well-being scale (WHO-5) and the Problem Areas in Diabetes (PAID) scale which measures diabetes-related distress. A composite stress score (CSS) (the occurrence of stressful life events and their reported degree of 'upset') between baseline and follow-up was calculated. Demographic data and medical record information were collected. Separate regression analyses were conducted with MDD and PHQ-9 scores as the dependent variables. RESULTS: In total, there were 7.4% (120) incident cases of MDD with 81.5% (1317) continuing to remain free of a diagnosis of MDD. Univariate analyses demonstrated that those with MDD were more likely to be female, less likely to be physically active, more likely to have diabetes complications at baseline and have higher CSS. Mean scores for the WHO-5, PAID and PHQ-9 were poorer in those with incident MDD compared with those who had never had a diagnosis of MDD. Regression analyses demonstrated that higher PHQ-9, lower WHO-5 scores and greater CSS were significant predictors of incident MDD. Significant predictors of PHQ-9 were baseline PHQ-9 score, WHO-5, PAID and CSS. CONCLUSION: This study demonstrates the importance of psychosocial factors in addition to physiological variables in the development of depressive symptoms and incident MDD in people with type 2 diabetes. Stressful life events, depressive symptoms and diabetes-related distress all play a significant role which has implications for practice. A more holistic approach to care, which recognises the interplay of these psychosocial factors, may help to mitigate their impact on diabetes self-management as well as MDD, thus early screening and treatment for symptoms is recommended.

Comorbidity within mental disorders: a comprehensive analysis based on 145 990 survey respondents from 27 countries.

AIMS: Epidemiological studies indicate that individuals with one type of mental disorder have an increased risk of subsequently developing other types of mental disorders. This study aimed to undertake a comprehensive analysis of pair-wise lifetime comorbidity across a range of common mental disorders based on a diverse range of population-based surveys. METHODS: The WHO World Mental Health (WMH) surveys assessed 145 990 adult respondents from 27 countries. Based on retrospectively-reported age-of-onset for 24 DSM-IV mental disorders, associations were examined between all 548 logically possible temporally-ordered disorder pairs. Overall and time-dependent hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. Absolute risks were estimated using the product-limit method. Estimates were generated separately for men and women. RESULTS: Each prior lifetime mental disorder was associated with an increased risk of subsequent first onset of each other disorder. The median HR was 12.1 (mean = 14.4; range 5.2-110.8, interquartile range = 6.0-19.4). The HRs were most prominent between closely-related mental disorder types and in the first 1-2 years after the onset of the prior disorder. Although HRs declined with time since prior disorder, significantly elevated risk of subsequent comorbidity persisted for at least 15 years. Appreciable absolute risks of secondary disorders were found over time for many pairs. CONCLUSIONS: Survey data from a range of sites confirms that comorbidity between mental disorders is common. Understanding the risks of temporally secondary disorders may help design practical programs for primary prevention of secondary disorders.

Social disability in different mental disorders.

OBJECTIVE: To assess the social disability of people with different psychiatric disorders. METHODS: Cross-site survey in five psychiatric hospitals (Dresden, Wroclaw, London, Michalovce and Prague). Working-aged patients diagnosed (ICD-10) with schizophrenia and related disorders (F2), affective disorders (F3), anxiety disorders (F4), eating disorders (F5) and personality disorders (F6), were assessed at admission (n=969) and 3 months after discharge (n=753) using the Brief Psychiatric Rating Scale and the Groningen Social Disability Schedule. The main outcome measure was Interviewer-rated social disability. RESULTS: During acute episodes patients with personality, eating and schizophrenic disorders functioned less effectively than those with affective or anxiety disorders. After controlling for age and severity of psychopathology, there was no significant effect of the diagnosis (during remission), sex, education and history of disorder on disability. Site, employment and partnership were significant factors for the level of social disability in both measure points. CONCLUSION: Severity of psychopathological symptoms, not the diagnosis of a mental disorder, was the most significant factor in determining the level of social functioning, particularly during the remission period. Site, employment and partnership appeared as significant factors influencing the level of social disability.

The energetics and structure of rutile TiO(2)(110).

Density functional theory and a pseudopotential plane wave method are applied to study electronic and structural properties of the defect-free TiO(2)(110) surface. The variations of the surface energy, work function, and atomic displacements are examined for partially and fully relaxed slabs modelling the rutile (110) surface, and consisting of up to 33 atomic layers. Relatively small relaxations of atomic positions in the outermost layers have a strong influence on the calculated surface energies and work functions. The effect of nonequivalence of the odd-even layer terminations is explored. A simple method is proposed which allows one to estimate accurate surface energies for relaxed systems from calculations for partially relaxed slabs.

Pathways to psychiatric care and reform of the public health care system in Poland.

OBJECTIVE: - Since 01.01.1999 a reform of the health care system in Poland has been realised based on the general health insurance act. We attempt to use the pathway method, especially measuring of time intervals along pathways, as a way of making accessibility to mental health services operational. METHOD: - In a period of 2 months all patients aged 15 and over who had not sought care from any public or private psychiatric service during the previous 365 days, were interviewed by psychiatrists, using the Polish version of the WHO Encounter Form. RESULTS: - A total of 228 patients were seen. The study reveals that the median interval between first seeing a primary care giver and arrival at a mental health service was 12 weeks, which is much longer than all other European centres in previous studies. CONCLUSION: - Making use of the pathway method and, in particular, median interval analysis between the onset of the mental health problem and seeing mental health professionals (MHPs) has shown practically limited access of patients, with a new episode of care to psychiatric services in both epidemiological catchment areas. This method seems to be a simple and inexpensive way of monitoring the accessibility to MHP in the period of health care reform.

[Applications of computer database in prospective studies on the mortality of patients with diagnosis of schizophrenia]. / Zastosowanie komputerowej bazy danych w prospektywnym badaniu umieralnosci pacjentów z rozpoznaniem schizofrenii.

The efficacy of epistemological research including the analysis of mortality rates depends to some extent on the ability to make use of registration systems and the processing of data. In the paper presented below the author outlines the application of a programme-dBase III plus, created for computer data bases and its use in the assessment of a prospective study of mortality of patients with a schizophrenic diagnosis. Three data bases (S295.DBF, SB295.DBF, GUS1982.DBF) of varying sizes were created, each of which possessed specific categories of information.

[Cost analysis of treating depression. Comparison of tricyclic antidepressants and selective serotonine re-uptake inhibitors]. / Ekonomiczna ocena leczenia depresji. Porównanie leków trójcyklicznych oraz selektywnych inhibitorów zwrotnego wychwytu serotoniny.

The question of costs in treating the most widely spread diseases has appeared in medical literature for several years. A task of modern health economics is to estimate and, if possible, to reduce direct and indirect costs of illnesses having social dimension. Since depression takes important place among them, it also stays in a circle of economists' interests. Latest changes in pharmacotherapy of depression, connected with appearence, by tricyclics, selective serotonine reuptake inhibitors, seem to be very promising: they have similar antidepressive effectiveness, but differ in toxicity after overdose, quantity and quality of side-effects, treatment dropout. However the organisation of Polish health service still passes over this economic aspect, it is probable that this situation will change in the nearest future, so it can be interesting to approach the methods of economic thinking in western psychiatric services.

[The influence of alprazolam on the symptoms of anxiety and depression]. / Wplyw alprazolamu na objawy leku i depresji.

[The diagnostic questionnaires and their use in epidemiological studies in psychiatry]. / Kwestionariusze diagnostyczne i ich zastosowanie w badaniach epidemiologicznych w psychiatrii.

The paper presents diagnostic instruments employed in psychiatric; brief history of their development with regard to their importance for progress in psychiatric epidemiology, the characteristic of the most important diagnostic questionnaire (Present State Examination--PSE, Composite International Diagnostic Interview--CIDI, Schedules for Clinical Assessment In Neuropsychiatry--SCAN, Structured Clinical Interview for DSM IV--SCID, Schedule for Affective Disorders and Schizophrenia--SADS, Diagnostic Interview Schedule--DIS). It also describes some features that should be considered while choosing a proper instrument for a given study. The authors call attention to some differences between instruments, e.g., those related to the structure of the questionnaire, involving diagnostic categories, the sort of information that an instrument allows to collect, competence of interviewers and their training, and also population for which the instrument is assigned. Presenting advantages and disadvantages of instruments, the authors emphasize that there is no best instrument. The choice of questionnaire depends, first of all, on the purpose of the study and the funds that the researches have at their disposal.
