The association of social inequality with the onset, persistence, and progression of psychotic experiences along the extended psychosis phenotype: a 6-year follow-up study in a community-based sample.

PURPOSE: This paper aims to investigate associations between early childhood and current indicators of socioeconomic inequality and the onset (incident), persistence and progression (increase in severity) of psychotic experiences (PEs) in a longitudinal follow-up of a community-based population. METHODS: Households in the metropolitan area of Izmir, Turkey were contacted in a multistage clustered probability sampling frame, at baseline (T1, n = 4011) and at 6-year follow-up (T2, n = 2185). Both at baseline and follow-up, PEs were assessed using Composite International Diagnostic Interview 2.1. The associations between baseline socioeconomic features and follow-up PEs were analysed using logistic regression models. Indicators of social inequality included income, educational level, current socioeconomic status (SES), social insurance, the area resided, ethnicity, parental educational level, and SES at birth. RESULTS: The risk of onset of PEs was significantly higher in lower education, lower SES, and slum-semi-urban areas. The persistence of PEs was significantly associated with the lowest levels of education and current SES, and rural residency. Persistent PEs were significantly and negatively associated with paternal SES at birth. Progression of PEs was significantly higher among respondents with educational achievements lower than university level and lower levels of SES, who have no social insurance and who reside in slum-semi-urban areas. Parental education and paternal SES at birth were not associated with the persistence of PEs. CONCLUSION: Indicators of social inequality (low education, low SES, low income, and poverty in the neighbourhood) were associated with the onset and persistence of PEs and progression along the extended psychosis phenotype. The early indicators seem to have a modest life-long impact on the psychosis phenotype.

Clinical Effects of Cannabis Use in First-Episode Acute Psychotic Patients.

Introduction: Cannabis is the most widely used illegal psychoactive substance worldwide. Although there are clinical studies examining the differences between psychotic symptoms emerging after cannabis use and non-cannabis-related psychotic symptoms, data are limited in the scientific literature. We aimed to investigate the effects of cannabis use on psychotic symptoms and compare the cognitive function differences between the cannabis-user and non-user groups. Methods: First-episode psychotic patients were included in the study and divided into two groups based on cannabis use. Participants with cannabis use and without cannabis use were compared in terms of socio-demographic factors, psychotic symptoms, cognitive functions, and childhood trauma. All patients were assessed twice, during recruitment and after treatment for psychotic symptoms. Results: A total of 38 patients comprising of 18 patients with a history of cannabis use and 20 patients without a history of cannabis use were included. There were significant correlations between cannabis use, and living apart from family and family history of substance abuse. Negative psychotic symptoms were higher in the non-user group. The negative psychotic symptoms improved more significantly after treatment in the non-user group. There was a significant correlation between cannabis use and Stroop Color-Word Test scores. Conclusion: Our results give us a chance to argue that psychosis has different features in people with and without a history of cannabis use. These two phenomena could differ in many ways, so different prevention strategies and treatment options should be considered.

The relationship between severity of overactive bladder symptoms and cognitive dysfunction, anxiety and depression in female patients with multiple sclerosis: Running head: OAB-V8, BICAMS and HAD scale in MS.

BACKGROUND: Overactive bladder (OAB), cognitive dysfunction, depression and anxiety are common problems encountered in MS. This study was planned to investigate the relationship between the severity of OAB symptoms and cognitive function, anxiety and depression in MS. METHODS: 100 patients with MS diagnosis with OAB symptoms were recruited. OAB symptoms was assessed with the OAB-V8 questionnaire. Symbol Digit Modalites Test (SDMT), California Verbal Learning Test II (CVLT-II) and Brief Vasospatial Memory Test-Revised (BVMT-R) in BICAMS Battery were used to evaluate cognitive function. Depression and anxiety were assessed with the Hospital Anxiety Depression (HAD) Scale. RESULTS: The mean age of the patients was 40.9±12.3, the duration of the disease was 9.03±6.89 years, and the mean OAB-V8 score was 17.6±8.9. SDMT test (r=-0.299, p<0.01) showed a moderately significant, CVLT-II (r= -0.219, p<0.05) and BVMT-R (r=-0.218, p<0.05) tests showed a weakly significant negative correlation with OAB-V8 score. There was a moderate positive correlation between the OAB-V8 score and HAD-D (r=0.279, p=0.005) and HAD-A (r=0.318, p=0.001) scores. SDMT and BVMT-R scores were significantly lower in anticholinergic (Ach) drug users (especially oxybutynin users) compared to those who did not use Ach drugs. CONCLUSIONS: It has been observed that the severity of OAB symptoms is related to worsening of information processing speed and an increase in depression and anxiety. It has been determined that there is a significant effect on information processing speed, visual learning and memory in patients using Ach drugs, especially in those using oxybutynin, compared to those who do not use Ach drugs.

A 6-year follow-up study in a community-based population: Is neighbourhood-level social capital associated with the risk of emergence and persistence of psychotic experiences and transition to psychotic disorder?

BACKGROUND: Social capital is thought to represent an environmental factor associated with the risk of psychotic disorder (PD). This study aims to investigate the association between neighbourhood-level social capital and clinical transitions within the spectrum of psychosis. METHODS: In total, 2175 participants, representative of a community-based population, were assessed twice (6 years apart) to determine their position within an extended psychosis spectrum: no symptoms, subclinical psychotic experiences (PE), clinical PE, PD. A variable representing change between baseline (T1) and follow-up (T2) assessment was constructed. Four dimensions of social capital (informal social control, social disorganisation, social cohesion and trust, cognitive social capital) were assessed at baseline in an independent sample, and the measures were aggregated to the neighbourhood level. Associations between the variable representing psychosis spectrum change from T1 to T2 and the social capital variables were investigated. RESULTS: Lower levels of neighbourhood-level social disorganisation, meaning higher levels of social capital, reduced the risk of clinical PE onset (OR 0.300; z = -2.75; p = 0.006), persistence of clinical PE (OR 0.314; z = -2.36; p = 0.018) and also the transition to PD (OR 0.136; z = -2.12; p = 0.034). The other social capital variables were not associated with changes from T1 to T2. CONCLUSIONS: Neighbourhood-level social disorganisation may be associated with the risk of psychosis expression. Whilst replication of this finding is required, it may point to level of social disorganisation as a public health target moderating population psychosis risk.

The Relationship between Alcohol-Cannabis Use and Stressful Events with the Development of Incident Clinical Psychosis in a Community-Based Prospective Cohort. / Toplum Tabanli Bir Örneklemin Ileriye Dönük Izleminde, Alkol- Esrar Kullaniminin ve Stresli Yasam Olaylarinin Klinik Psikoz Gelisimi ile Iliskisi.

OBJECTIVE: The aim of this study is to evaluate the associations between alcohol-cannabis use and forensic/stressful events with the risk of incident clinical psychosis during follow-up. METHOD: A community-based sample (n: 2142) was screened for clinical psychosis (schizophrenia and other psychotic disorders, affective disorders with psychotic features) at baseline and follow-up. Thus, incident clinical psychosis cases to develop during follow-up (individuals with no clinical psychosis at the baseline assessment and with clinical psychosis at the follow-up assessment) were detected (n: 27). These cases and the controls who did not report any psychotic symptoms at the follow-up assessment (n: 1691) were compared for exposure to environmental risk factors during follow-up (total n: 1718). RESULTS: Individuals reporting heavy alcohol drinking or cannabis use during follow-up had significantly higher risk of incident clinical psychosis. The monthly frequency of drinking and cannabis use was also associated with the risk. Higher number of stressful life events exposed predicted higher risk of incident clinical psychosis. The risk of incident clinical psychosis was significantly higher in case of coexistence of two risk factors (heavy drinking, cannabis use, ≥3 stressful events), in comparison with the existence of a single risk factor (17.7 vs. 1.6%, p<0.001). CONCLUSION: Heavy drinking, cannabis use, forensic events and stressful events were associated with the risk of incident clinical psychosis. The coexistence of multiple stressful events and disorders related to abuse of alcohol/cannabis should be considered as a warning for the development of clinical psychosis.

Relationship Between Serum Agouti-Related Peptide Levels and Metabolic Syndrome in Euthymic Bipolar Patients.

INTRODUCTION: Agouti-Related Peptide (AgRP) is expressed primarily in the hypothalamic arcuate nucleus, stimulates appetite and decreases metabolism and energy expenditure. The aim of our study is to evaluate the relationship between serum Agouti-Related Peptide (AgRP) levels and metabolic syndrome in euthymic bipolar patients. METHODS: Forty euthymic bipolar patients who used only mood stabilizer for at least three months and 40 healthy volunteers as control group were included in the study. We measured fasting blood glucose levels and serum levels of AgRP, total cholesterol, triglyceride, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) of all participants. The main outcome measure was the difference between patients and control groups in terms of metabolic syndrome frequency and the relationship between serum AgRP level and metabolic syndrome is also investigated. RESULTS: The metabolic syndrome was significantly more common in euthymic bipolar patients than in control group (p=0.039). Additionally, levels of blood glucose and triglyceride were significantly higher in the patient group than in the control group (p=0.006 and 0.01 respectively). Serum AgRP levels did not differ between the patient and control groups (p=0.35). Also, in euthymic bipolar patients, there was no significant difference in serum AgRP levels between patients with metabolic syndrome and those without (p=0.754). CONCLUSION: We found significantly higher frequency of metabolic syndrome in euthymic bipolar patients than in the control group. However, there was no significant difference in the levels of serum AgRP between bipolar patients with and without metabolic syndrome in either study groups.

Testing an Internet-Based Turkish Obesity Behavioral Therapy Program: A Randomized Study. / Internet Tabanli Türkçe Obezite Davranisçi Terapi Programinin Test Edilmesi: Bir Seçkisiz Çalisma.

OBJECTIVE: Behavioral treatment is recommended as the first line intervention for the prevention of health problems pertaining to obesity. Internet-based programs are used to provide cognitive behavioral therapy for psychiatric disorders and systemic diseases to a large number of patients at low cost. The aim of this study is to develop the first internet based Turkish obesity behavioral therapy program and test its short-term effectiveness. METHOD: A Turkish web-based behavioral therapy program based on the behavioral strategies employed in the Diabetes Prevention Program was generated. In order to test the effectiveness of this internet-based program an eight week randomized study was conducted. A total of 101 overweight participants with body mass index in the 25-40 range were randomly assigned to an eight-week weight loss program using either the Internet Behavior Therapy (IBT, n=51) or e-mail education (EE, n=50). The participants in the IBT group were provided access to an Internet program that provided videos teaching behavioral weight-loss skills as well as a self-monitoring platform to calculate the daily calorie balance. The participants in the EE group received weekly e-mails with information on healthy eating, physical exercises and weight loss for eight weeks. The primary outcome measure was the observed weight change at the end of the 8 weeks. RESULTS: In the analyses wherein baseline weight was carried forward for missing data, the IBT produced significantly larger mean weight loss in comparison to the EE at the end of the 8 weeks [2.28 kg (2.11) vs. 0.74 kg (1.57), p=0.001]. The participants in the IBT group, when compared to the EE group, were also more likely to achieve a clinically significant weight loss of 5% of their initial body weight at the end of the 8-week study period (17.6% vs. 2%, p=0.016). CONCLUSION: The participants who received a structured IBT intervention lost significantly more weight after two months, compared to those who received weekly informational emails regarding weight loss. Internet-based behavioral therapy programs may have the potential to serve as a low-cost alternative for obese patients.

The effect of Attention Deficit and Hyperactivity Disorder on Antiretroviral Treatment and Appointment Adherence among adults living with HIV.

INTRODUCTION: The most prominent characteristic of adult attention deficit hyperactivity disorder (ADHD) is impulsive behavior and deficits in executive functions, which require long-term organization and discipline. This may have serious implications in terms of adherence to treatment among adults living with HIV (PLWH). This study aimed to determine the prevalence of ADHD among non-perinatally infected PLWH and its effect on adherence to antiretroviral treatment (ART) and scheduled appointments. METHODOLOGY: The PLWH admitted to our centers between January 2012 and February 2016 were invited to the study. ADHD diagnosis was made according to the novel criteria guided interviews. The first ART interruption for ≥ 6 days per month (≤ 80%) was defined as ''ART-event'' and the first non-attendance of any scheduled appointment was defined as ''appointment-event''. Kaplan-Meier plot with a Log-rank test was used for event-free adherence (EFA). RESULTS: Twenty-five patients out of 85 were diagnosed with ADHD (29.4 %) which was significantly higher than the highest percentage reported (7.3 %) for the general population (p < 0.0001). Both ART-event (p = 0.0002) and appointment-event (p = 0.02) were significantly higher among ADHD participants compared to those without. Additionally, both ART-EFA (p = 0.00014) and appointment-EFA (p = 0.023) were significantly shorter among ADHD participants compared to those without. CONCLUSION: ADHD is significantly higher in adult PLWH and people with ADHD had a significant tendency for non-adherence to ART and follow-up. Screening for ADHD as well as providing treatment when required would be beneficial to achieve and maintain virologic success.

Izmir Mental Health Cohort for Gene-Environment Interaction in Psychosis (TürkSch): Assessment of the Extended and Transdiagnostic Psychosis Phenotype and Analysis of Attrition in a 6-Year Follow-Up of a Community-Based Sample.

Objective: TürkSch is a prospective, longitudinal study in a representative community sample (Izmir, Turkey), consisting of several data collection stages, to screen and follow-up mental health outcomes, with a special focus on the extended and transdiagnostic psychosis phenotype. The aim of the present paper is to describe the research methodology, data collection results, and associations with noncontact and refusal in the longitudinal arm. Methods: Households were contacted in a multistage clustered probability sampling frame, covering 11 districts and 302 neighborhoods at baseline (n = 4,011) and at 6-year follow-up (n = 2,185). Both at baseline and at follow-up, participants were interviewed with the Composite International Diagnostic Interview. Participants with probable psychotic disorder were reinterviewed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID)-I either at the hospital or at the participant's residence. Relevant neighborhood-level measures were assessed in a separate sample (n = 5,124) in addition to individual-level measures. Candidate gene-by-environment interactions were investigated using two nested case-control studies. Results: Individuals with a mental health problem had lower refusal rates. Older and lower educated individuals had a lower probability of noncontact. Discussion: The TürkSch study has an advanced design to meet the challenges of evaluating the multidimensional etiological and phenomenological nature of the extended and transdiagnostic psychosis phenotype.

Psychotic experiences and mood episodes predict each other bidirectionally: a 6-year follow-up study in a community-based population.

BACKGROUND: Psychotic experiences (PEs) are not exclusive to psychotic disorders and highly correlated with mood episodes. In this representative general population-based study, longitudinal bidirectional associations between the extended psychosis phenotype and mood episodes were investigated, accounting for other possible causes. METHODS: Households were contacted in a multistage clustered probability sampling frame covering 11 districts and 302 neighbourhoods at baseline (n = 4011) and at 6-year follow-up (n = 2185). Participants were interviewed with the relevant sections of the composite international diagnostic interview both at baseline and at follow-up. Sociodemographic, familial and environmental risk factors associated with the extended psychosis phenotype and mood episodes were assessed. Logistic regression and cross-lagged panel correlation models were used for the associations between the extended psychosis phenotype and mood episodes. RESULTS: PEs were associated with subsequent depressive and manic episodes. There was bidirectionality in that mood episodes were associated with subsequent PEs, and PEs were associated with subsequent mood episodes. The associations occurred in a sub-additive pattern. There were substantial synchronous and cross-lagged correlations between these psychopathology domains, with reciprocally similar cross-lagged correlations. Familial risk and adverse life events were associated with both psychopathology domains, whereas some sociodemographic risk factors and alcohol/cannabis use were associated with only one domain. CONCLUSION: The sub-additive bidirectional associations between PEs and mood episodes over time and the similarity of cross-lagged correlations are suggestive of mutually causal connections between affective and psychotic domains of psychopathology.

Is BDNF-Val66Met polymorphism associated with psychotic experiences and psychotic disorder outcome? Evidence from a 6 years prospective population-based cohort study.

There is little research on genetic risk for the extended psychosis phenotype ranging from psychotic experiences (PEs) to psychotic disorders (PDs). In this general population-based prospective cohort study, the longitudinal associations between BDNF-Val66Met polymorphism and the different levels of the extended psychosis phenotype were investigated. Addresses were contacted in a multistage clustered probability sampling frame covering 11 districts and 302 neighborhoods at baseline (n = 4011). A nested case-control study (n = 366) recruited individuals with PEs and PDs as well as individuals with no psychotic symptoms. In this subgroup, blood sampling for genetic analysis and assessment of environmental exposures were carried out, followed by clinical re-appraisal at follow-up 6 years later (n = 254). The BDNF-Val66Met polymorphism was significantly associated with the extended psychosis phenotype. The pattern of the association was that the BDNF-Val66Met polymorphism impacted in a dose-response but extra-linear fashion, with stronger impact at the PD end of the extended psychosis phenotype. Associations were still significant after adjusting for sociodemographic factors and environmental exposures including life events, childhood adversity, socioeconomic status, urbanicity, and cannabis use. The BDNF-Val66Met polymorphism may index susceptibility to expression of psychosis along a spectrum.

DSM outcomes of psychotic experiences and associated risk factors: 6-year follow-up study in a community-based sample.

BACKGROUND: Psychotic experiences (PEs) may predict a range of common, non-psychotic disorders as well as psychotic disorders. In this representative, general population-based cohort study, both psychotic and non-psychotic disorder outcomes of PE were analysed, as were potential moderators. METHODS: Addresses were contacted in a multistage clustered probability sampling frame covering 11 districts and 302 neighbourhoods at baseline (n = 4011). Participants were interviewed with the Composite International Diagnostic Interview (CIDI) both at baseline and at 6-year follow-up. Participants with PE at baseline were clinically re-interviewed with the SCID-I at follow-up. The role of socio-demographics, characteristics of PE, co-occurrence of mood disorders and family history of mental disorders were tested in the association between baseline PE and follow-up diagnosis. RESULTS: In the participants with baseline PE, the psychotic disorder diagnosis rate at follow up was 7.0% - much lower than the rates of DSM-IV mood disorders without psychotic features (42.8%) and other non-psychotic disorders (24.1%). Within the group with baseline PE, female sex, lower socio-economic status, co-occurrence of mood disorders, family history of a mental disorder and persistence of PE predicted any follow-up DSM diagnosis. Furthermore, onset of psychotic v. non-psychotic disorder was predicted by younger age (15-30 years), co-presence of delusional and hallucinatory PE and family history of severe mental illness. CONCLUSION: The outcome of PE appears to be a consequence of baseline severity of multidimensional psychopathology and familial risk. It may be useful to consider PE as a risk indicator that has trans-diagnostic value.

[The Association between the Extended Psychosis Phenotype and COMT val158met and BDNF val66met polymorphisms]. / Genis Psikoz Fenotipinin COMT val158met ve BDNF val66met Polimorfizmleri ile Iliskisi.

OBJECTIVE: Psychotic disorders were previously associated with catechol- O-methyltransferase (COMT) val158met (rs4680) and brain-derived neurotrophic factor (BDNF) val66met (rs6265) polymorphisms. This article evaluates the association between COMT/BDNF polymorphisms and the extended psychosis phenotype which covers not only schizophrenia but also subclinical expressions of psychotic experiences. METHOD: The participants of this study were part of the TürkSch (Izmir Mental Health Survey for Gene-Environment Interaction in Psychoses), a longitudinal study Psychotic experiences and disorders were screened 437. The extended psychosis phenotype was grouped into four: (1) no psychotic experiences (n: 194), (2) subclinical psychotic experiences (n: 87), (3) clinically relevant psychotic experiences (n: 104), and (4) schizophrenia-like disorders (n: 52). BDNF rs6265 was genotyped occurred in every participant whereas COMT rs4680 genotyping could be done on 366 individuals. RESULTS: There was no association between the extended psychosis phenotype and BDNF rs6265/COMT rs4680 polymorphisms. The frequency of met carriers in the BDNF rs6265genotype was slightly higher in individuals with subclinical psychotic experiences than in the group with no psychotic experiences, which was just below the significance level (p=0.08). CONCLUSION: The lack of an association between different expression levels of the extended psychosis phenotype and the BDNF rs6265/ COMT rs4680 polymorphism might be related to sample characteristics, underlying gene-gene, gene-environment and gene-environment-gene interactions.

The epidemiology of alcohol use in Izmir, Turkey: drinking pattern, impairment and help-seeking.

PURPOSE: There is no report on various patterns of alcohol drinking and related impairment, help-seeking in Turkey. We investigated the 12-month prevalence and correlates of drinking patterns and alcohol use disorders in the general population of Izmir-Turkey, with further analyses on role impairment and help-seeking. METHOD: A multi-stage clustered area probability sample of adult household residents in the Izmir Metropolitan Area was assessed using the Composite International Diagnostic Interview 2.1 (n  = 4011). Estimation focused on prevalence and correlates of 12-month drinking pattern and DSM-IV alcohol use disorders. The 12-month drinking pattern included groups of non-regular users, regular non-heavy drinkers, regular heavy drinkers, and alcohol abuse disorder and alcohol dependence. All respondents were questioned about receiving 12-month treatment for any psychological complaints, the route of help-seeking, and were assessed with Short Form-36 for functional impairments. Multinomial logistic regression was used for underlying associations between the covariates and the drinking patterns. RESULTS: The rate of lifetime alcohol abstinence was 52.3% while the prevalence of past-year users was 14.8%. The 12-month prevalence estimates of regular heavy drinkers, and alcohol abuse disorder and dependence were 2.5%, 3.2 and 1.6%, respectively. Any of the drinking patterns and alcohol use disorders was associated with male gender, and higher levels of education, monthly income and socioeconomic status. Alcohol dependence was associated with mental health impairment but not with physical impairment. The 12-month rates of help-seeking in alcohol abuse and dependence were 11.6 and 16.5%. CONCLUSION: Although alcohol use disorders are lower than estimates of Western countries, alcohol use constitute a major reason of disability with prominent treatment gap.

The epidemiology of major depressive disorder and subthreshold depression in Izmir, Turkey: Prevalence, socioeconomic differences, impairment and help-seeking.

BACKGROUND: Subclinical and clinical depression is common, widely distributed in the general population, and usually associated with role impairment and help-seeking. Reliable information at the population level is needed to estimate the disease burden of depression and associated care needs in Turkey. METHOD: The cross-sectional study aimed to assess the prevalence of subthreshold (SubD) and clinical major depressive disorder (MDD) in Izmir, Turkey. In the 5242 eligible households, a total of 4011 individuals were successfully interviewed, yielding a response rate of 76.5%. Prevalence estimates of MDD and SubD depression were formed by using the responses to the questions of the CIDI section E. Short Form 36 (SF-36) to assess health status and functional impairments in eight scaled scores during the last four weeks. All respondents were questioned about receiving 12-month treatment for any psychological complaints, the route of help-seeking, as well as prescribed medicines and any hospitalization. RESULTS: The one year prevalence estimate for CIDI/DSM IV MDD was 8.2% (95% CI, 7.4-9.1). Less educated, low income, uninsured, low SES, unemployed/disabled and housewives, slum area residents had higher one year MDD prevalence. Determined prevalence of help seeking from mental health services of SubD and MDD cases were 23.6%, 30.6% respectively. Only 24.8% of clinically depressive patients received minimally adequate treatment. LIMITATIONS: Cross sectional design. CONCLUSION: Higher MDD prevalence correlates with younger ages, female gender, unemployment, less education, lower monthly income, lower SES and uninsurance. Help seeking from mental health services were low. There are treatment gap and impairment in depressive group.

[Case management based multidisciplinary care protocol in the palliative care of cancer patients]. / Kanser hastasinin palyatif bakiminda vaka yönetimine dayali multidispliner bakim protokolü.

Today, multifaceted approach is needed for the palliative care of advanced stage cancer patients. The main objective for these patients, elimination of pain and other symptoms, psychosocial and spiritual needs are met and to increase the quality of life. We are also faced with the challenge of meeting the physical and psychosocial needs of family members. The purpose of a holistic approach to patient and family who provide effective and quality care, care coordination and case management of a multidisciplinary team approach is based on cooperation. Care protocols specified patient care activities to be carried by the related disciplines to achieve results on a timeline that shows a certain, a multidisciplinary clinical management tool. A lot of care guidelines and protocols developed by a team of experts to contribute to the palliative care activities, and this is thought to be a guiding team members, working with patients.

[Lifetime prevalence and correlates of schizophrenia and disorders with psychotic symptoms in the general population of Izmir, Turkey]. / Izmir kent merkezinde sizofreni ve psikotik belirtili bozukluklarin yasamboyu yayginligi ve iliskili olduklari sosyodemografik özellikler.

OBJECTIVE: To estimate the lifetime prevalence of 12 DSM-IV disorders with psychotic symptoms in a general population survey. METHOD: Addresses were contacted in a multistage clustered area probability sampling frame of administrative neighbourhoods and households, covering 9 districts and 302 neighbourhoods in the Izmir metropolitan area between November 2007 and October 2008. One household member aged between 15 and 64 years and available to complete the interview was randomly selected using a within-household sampling method. The primary screening instrument was the Composite International Diagnostic Interview 2.1. A systematic screening procedure was implemented to detect probable cases with any psychotic disorder. Those selected by the screens were re-interviewed with the Structured Clinical Interview for DSM-IV. Diagnoses of individuals who were not available for re-interview were made by combining screening information with case register diagnoses and/or the telephone interviews with relatives or spouse. RESULTS: A total of 4011 individuals were screened for disorders with psychotic symptoms. After screening, 499 respondents were selected as a probable case. 277 of screen positive respondents were available for clinical reappraisal. Initial screening interviews and additional material were used for best estimate diagnoses of the remaining 172 respondents. Total lifetime prevalence of 12 DSM-IV disorders with psychotic symptoms was 2.62%. Lifetime prevalence of each disorder separately were as follows: 0.74% for schizophrenia, 0.20% for schizoaffective disorder, 0.05% for schizophreniform disorder, 0.10% for delusional disorder, 0.12% for brief psychotic disorder, 0.55% for major depressive disorder with psychotic features, 0.37% for bipolar I disorder, 0.20% for substance induced psychotic disorder, and 0.07% for psychotic disorders due to a general medical condition. CONCLUSION: Total lifetime prevalence of disorders with psychotic symptoms is higher than any previously reported estimates in Turkey; with a prevalence of approximately 2.5%, these disorders can be considered a major public health concern.

Irritable bowel syndrome in renal transplant patients: prevalence, link with quality of life, anxiety, and depression.

BACKGROUND: Gastrointestinal complications are common in renal transplant recipients and may arise from any part of the gastrointestinal tract. Irritable bowel syndrome (IBS) is highly common in the general population, but the status is not known in renal transplant patients. In this study, we evaluated the prevalence of IBS and its association with health-related quality of life (HRQOL), anxiety, and depression in renal transplant patients. METHODS: One hundred and ninety-eight patients were enrolled in this study. Sociodemographic and laboratory variables were recorded. Severity of depressive and anxiety symptoms and HRQOL were assessed by the Beck Depression Inventory, State-Trait Anxiety Inventory, and Short Form 36 (SF-36), respectively. Diagnosis of IBS was based on Rome III criteria. RESULTS: The mean age was 38 ± 10 years and 61% were male. The mean transplant duration was 62 ± 54 months. Among 198 patients, 55 (27%) had IBS. Patients with IBS had lower SF-36 scores and had higher depressive and anxiety symptoms than patients without IBS. CONCLUSIONS: IBS is highly prevalent in renal transplant patients. The presence of IBS is closely related with HRQOL anxiety and depression.

[Psychotic disorders among immigrants from Turkey in Western Europe: An overview of incidences, prevalence estimates, and admission rates]. / Bati Avrupa Ülkelerinde Yasayan Türkiye Kökenli Göçmenlerde Psikotik Bozukluklar: Siklik, Yayginlik ve Basvuru Oranlari Üzerine Bir Derleme.

OBJECTIVE: To provide an overview of incidence and prevalence estimates, admission rates, and related features of psychotic disorders among immigrants from Turkey in Western Europe. METHOD: Articles published in all languages between 1990 and 2010 were included. In order to detect relevant studies, a string ([schizo* OR psych*] AND [Turk*] AND [migra* OR immigra*]) was used in MEDLINE and PsychINFO. Turkish indexes and abstracts books of national congresses were also screened to locate additional papers. RESULTS: We included 21 studies which yielded 25 rates on psychotic disorders among immigrants from Turkey. Fifteen papers reported rates for the immigrants from Turkey in The Netherlands, four for Germany, one for Denmark and one for Switzerland. The incidence estimates of non-affective and affective psychosis among immigrants from Turkey were between 38.5 and 44.9 per 100,000 while incidence estimates of schizophrenia were between 12.4 and 63.8 per 100,000. The prevalence estimates of schizophrenia and other psychotic disorders were between 1.1 and 6.2 per 1,000. Rates and relative risks of psychotic disorders in immigrants from Turkey tended to be higher than the natives and lower than other immigrant groups with similar sociocultural background. In addition to other risk factors, social contextual factors including discrimination and neighbourhood characteristics were the key environmental factors that modulate rates of psychotic disorders among immigrants from Turkey. Males were under a higher risk of incidence, prevalence estimates, and admission rates. CONCLUSION: Variations in rates and relative risks indicate a possible etiological role of social experiences in immigrants. Studies with a focus on comparing the rates and the social factors of psychotic disorders between immigrants from Turkey in Western Europe and their family members residing in Turkey may provide additional insight into the epidemiology of psychotic disorders.
