Comorbidity of mental disorders - epidemiological data
W artykule przedstawiono koncepcję współchorobowości z perspektywy epidemiologicznej. Dokonano przeglądu
badań z całego świata, o najwyższych standardach metodologicznych (opierających się na standaryzowanych
narzędziach, co najmniej kilkutysięcznych próbach, dobieranych losowo).
Mimo kontrowersji związanych z samym pojęciem współchorobowości (w całym obszarze psychiatrii), pewne
wnioski powtarzają się, skłaniając do rozważenia możliwości ich wykorzystania na przykład w organizacji opieki
zdrowotnej. Psychiatria 2010; 7, 1: 1-10This paper presents the concept of comorbidity in a perspective of epidemiology. A review of surveys from all
over the world of the highest methodological standards has been done (which are: standardized diagnostic
instruments, samples of at least few thousands participants and random selection).
Despite of many controversies, connected with the idea of comorbidity (in the whole field of psychiatry), some of
the conclusions are the same and, by that, they lead to reflections on, for example, health care organization.

Validation of the Polish version of WHO-5 as a screening instrument for depression in adults with diabetes
Aims
The aim of this study was to validate and report the factorial analysis of the World Health Organization’s 5-item Well-being Index (WHO-5) among outpatients with type 2 diabetes.
We investigated the psychometric properties of the WHO-5 and its suitability for identifying potential depressive symptoms in Polish adults with diabetes.
Methods
Participants were randomly chosen among Polish diabetes outpatients and invited to participate in the cross-sectional study (N = 216). Participants completed the Polish version of the WHO-5, Problem Areas in Diabetes Scale and Patient Health Questionnaire.
Results
Factor analyses identified the one-factor structure of the Polish version of the WHO-5. The internal consistency of the Polish version of the WHO-5 is satisfying. With regard to convergent validity, there were significant negative associations between the WHO-5 and PAID, the PHQ-9, HbA1c and the amount of medical complications. The AUC indicates that the WHO-5 is an effective measure for identifying depressive symptoms. The optimal cut off values of ≤12 yielded the best sensitivity/specificity trade-off for identifying depression among people with diabetes.
Conclusions
The Polish version of the WHO-5 is a reliable, valid outcome measure for outpatients with type 2 diabetes and can be a useful instrument for screening for depression in people with diabetes
q1Bipolar spectrum features in drug resistant unipolar depression patients : TRES-DEP pilot study
People with diabetes need a lower cut-off than others for depression screening with PHQ-9
Aims: This study evaluated the psychometric characteristics of the Polish version of the PHQ-9 in detecting major depression (MDD) and ‘MDD and/or dysthymia’ in people with and without type 2 diabetes. Methods: Participants were randomly selected from a diabetes outpatient facility (N = 216) and from among patients admitted to a medical center and psychiatric hospital (N = 99). The participants completed the PHQ-9. The Hamilton Depression Rating Scale and the Mini International Neuropsychiatric Interview were used to identify the presence of psychiatric symptoms. The optimal cut-offs for PHQ-9 in people with and without type 2 diabetes were investigated based on two methods: 1) Youden’s index which identifies cut-off points useful in scientific research; 2) a second method of two-stage screening for depressive disorders to provide guidance for clinical practice. Results: The Polish version of the PHQ-9 is a reliable and valid screening tool for depression in people with and without type 2 diabetes. An optimal cut-off of ≥ 7 was indicated by Youden’s index and ≥ 5 by the two-stage method for screening for MDD and ‘MDD and/or dysthymia’ in the group with type 2 diabetes. A cut-off of ≥ 11 was optimal for screening for both MDD and ‘MDD and/or dysthymia’ among people without diabetes (Youden’s index). The two-stage approach suggested a ≥ 10 score for screening for MDD and ≥ 9 for screening for ‘MDD and/or dysthymia’ in people without diabetes. Conclusions: A lower cut-off score of the PHQ-9 is recommended for people with type 2 diabetes as compared to the general population
Interleukin-6: the missing element of the neurocognitive deterioration in schizophrenia? The focus on genetic underpinnings, cognitive impairment and clinical manifestation
Genetic variants in transforming growth factor-β gene (TGFB1) affect susceptibility to schizophrenia
Immense body of evidence indicates that dysfunction of immune system is implicated in the etiology of schizophrenia. The immune theory of schizophrenia is supported by alterations in cytokine profile in the brain and peripheral blood. Given the strong genetic background of schizophrenia, it might be assumed that aberrant production of cytokines might be the consequence of genetic factors. This study aimed at investigating the association between schizophrenia susceptibility and selected functional polymorphisms in genes encoding cytokines including: interleukin-2 (IL2 −330T>G, rs2069756), interleukin-6 (IL-6 −174G>C, rs1800795), interferon-γ (IFNG +874T>A, rs2430561) as well as for the first time transforming growth factor-β1 (TGFB1 +869T>C, rs1800470 and +916G>C, rs1800471). We recruited 151 subjects with schizophrenia and 279 controls. There was a significant difference in the genotype distribution and allelic frequency of the TGFB1 +869T>C between patients with schizophrenia and healthy controls (p < 0.05). The risk of schizophrenia was more than two-fold higher in carriers of T allele (CT+TT genotypes) than individuals with CC genotype. Given documented gender differences in incidence of schizophrenia, we conducted separate analyses of male and female participants. We have shown that the association was significant in females, while in males it reached a trend toward statistical significance. To the best of our knowledge, it is the first report showing the association between TGFB1 +869T>C polymorphism and schizophrenia

PAID-PL—The Polish Version of the Problem Areas in Diabetes Scale: Perfect Reliability and a One-Factor Structure
Purpose: The aim of this study was to assess the structure and validate the Polish version of the Problem Areas in Diabetes (PAID) scale, as the current translations of the original English version significantly vary in their psychometric properties.
Patients and Methods: Two hundred and sixteen consecutive Polish outpatients were invited to participate in this international cross-sectional study on depression in diabetes. The research was based on the demographic and clinical characteristics of the study population, including the level of glycated hemoglobin (HbA1c) and scores obtained in the Polish versions of the following questionnaires: PAID, World Health Organization-Five Well-Being Index (WHO-5), Patient Health Questionnaire 9 (PHQ-9). The psychiatric diagnosis was conducted with the use of Mini-International Neuropsychiatric Interview (M.I.N.I.).
Results: Exploratory factor analyses yielded a 1-factor structure that included all 20 items. The internal consistency of the Polish version of PAID was high (Cronbach α = 0.97). There were significant positive correlation between PAID and PHQ-9 and a negative correlation between PAID and WHO-5. We also observed a negative association between PAID scores and age and a positive correlation between PAID and HbA1c levels. Patients with depression reported significantly higher PAID scores as compared with those without depressive symptoms.
Conclusion: The Polish version of PAID has a one-factor structure and is a reliable, valid outcome measure for Polish outpatients with type 2 diabetes and it may constitute a useful instrument for screening for psychologic issues in diabetic patients during their appointments at the diabetes clinic
CAUSES OF MORTALITY IN SCHIZOPHRENIA: AN UPDATED REVIEW OF EUROPEAN STUDIES
Background: The excess mortality in schizophrenia is still a phenomenon insufficiently studied on the cross-national level. It is
important to analyse current studies on morality in schizophrenia since significant changes have recently taken place in psychiatric
health care systems and guidelines of pharmacological treatment have been developed in European countries.
Subjects and methods: This article reviews studies addressing mortality in schizophrenia in Europe that were published in
English in the Pubmed database in 2009-2014. It aimed at determining countries where studies were conducted, methodologies and
tools used, and current main mortality rates, as well as direction of causality in this group of patients.
Results: The recently published studies were conducted only in few European countries. The majority of data was obtained from
general medical records and death records. The studies indicate that schizophrenia patients are characterized by higher mortality
rate than the general population, with natural causes (cardiovascular diseases and cancers) and suicides predominating. The
increasing mortality gap with significantly shorter life expectancy of patients with schizophrenia in comparison with the general
population is considerable.
Conclusions: Death records are a crucial tool in studies on mortality in schizophrenia patients; however they are insufficiently
employed. Recent European reports do not show positive tendencies, indicating that standardized mortality rates in schizophrenia
remain on the same level or even increase, particularly for deaths resulting from natural causes. Due to various methodologies used
in studies, their direct comparison is difficult. This limitation warrants further discussion on methods used in future studies on
schizophrenia mortality in Europe
Study protocol for the development of a European measure of best practice for people with long term mental health problems in institutional care (DEMoBinc)
Background: This study aims to build a measure for assessing and reviewing the living conditions, care and human rights of people with longer term mental health problems in psychiatric and social care institutions. Protection of their human rights is imperative since impaired mental capacity secondary to mental illness can make them vulnerable to abuse and exploitation from others. They also constitute a major resource pressure for mental health services, social services, informal carers and society as a whole.Methods/Design:domains are identified by collating results from: i) a systematic review of the literature on institutional care for this service user group; ii) a review of the relevant care standards in each participating country; iii) Delphi exercises in partner countries with mental health professionals, service users, carers and advocates. Common domains and cross-cutting themes are agreed by the principal researchers and an international expert panel. Items are developed to assess these domains and incorporated into the toolkit which is designed to be administered through a face to face interview with the institution's manager. The toolkit is refined in response to inter-rater reliability testing, feedback from interviewers and interviewees regarding its utility, and feedback from key stakeholders in each country about its ability to deliver information that can be used within each country's established systems for quality assessment and review. Cross-validation of the toolkit ratings against service users' quality of life, autonomy and markers of recovery tests whether it can deliver a proxy-measure of the service users' experiences of care and the institution's promotion of their human rights and recovery. The ability of the toolkit to assess the "value for money" delivered by institutions is investigated by comparing toolkit ratings and service costs.The study will deliver the first international tool for the assessment of the quality of institutional care for people with longer term mental health problems that is accurate, reliable, informative, useful and easy to use
