Burnout and Related Factors in Caregivers of outpatients with Schizophrenia

Objectives: Care of a person with schizophrenia involves multiple problems, possibly leading to burnout which is a culturally influenced phenomenon. The aim of this study was to investigate burnout and related factors in caregivers of outpatients with schizophrenia. Methods: Subjects included in the study were 40 primary caregivers of outpatients with schizophrenia (15 males, 25 females) whom were assessed with the Maslach Burnout Inventory (MBI), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). Patients were also administered the Calgary Depression Scale (CDS). Also, sociodemographic information about patients and their caregivers were taken. The significance of differences between two groups was determined by Mann-Whitney U-test. The relationships between the variables were evaluated by Pearson correlation analysis. Results: No significant difference was found in the MBI subscale scores in terms of caregivers gender, marital status, and education, being a family member, having enough information about the illness and taking support during caregiving. Emotional Exhaustion and Personal Accomplishment subscale scores of the caregivers were significantly different in terms of patients’ adaptation to treatment or not (respectively; p=0.010, p=0.030). The MBI-Emotional Exhaustion scores revealed significant positive correlations with the BDI and BAI total scores. Also, the MBI- Depersonalization scores and the BAI scores were positively correlated. Conclusions: Burnout levels in caregivers of patients with schizophrenia were lower when compared with other cultures. Only treatment compliance predicted burnout, while other factors were excluded. Therefore, professionals have to help to patients primarily adapt to their treatment

Endogenous And Exogenous Attention In Alzheimer Type Of Dementia: Effect Of Target Position

Objective: Endogenous attention (EnA) is an ability in goal-driven processes, controlled by top-down mechanisms and exogenous attention (ExA) is an ability in stimulus-driven processes, controlled by bottomup mechanisms. In the present research, it was aimed to investigate in Alzheimer's disease (AD) the EnA and ExA processes in relation to target position (right/left) by using the Spatial Cueing Paradigm (SCP). Method: The study was conducted with the participants of 65-90 year age range, consisting of 14 female and 14 male (n=28) participants diagnosed with AD and 12 female and 12 male (n=24) healthy volunteers as controls. The group variable (AD, Control) was tested on the intergroup basis; and the attention type (EnA, ExA), trial type (valid /VT+ and invalid/ VT-) and the target position (left/right) variables were tested on the intra-subject basis (within subject design). Two separate factorial ANOVAs were conducted for mean reaction time and accuracy measures obtained from SCP. Results: In comparison to the control group, the AD group participants gave slow and wrong reactions to stimuli for EnA and ExA. The AD group responses were faster in the VT+s and more accurate in the VT-s to stimuli on the left as compared to those on the right; and the responses of AD patients to the stimuli on the left as compared to those on the rieht was more accurate in VT-s under ExA condition. Conclusion: AD causes impairment of EnA and ExA. Faster reactions by AD participants to the target on the left in VT+s and more accurate reactions to the target on the left in VT-s are in agreement with reports in the literature on the lateralization of visual-spatial attention (VSA) in the right hemisphere. In this study, also in agreement with previous reports, lateralization in AD was noted in favour of the stimuli on the left in ExA.WoSScopu

Exploring the Role of Social Anhedonia in the Positive and Negative Dimensions of Schizotypy in a Non-Clinical Sample

Introduction: The present study aimed to investigate the role of social anhedonia, defined as the lack of ability to feel pleasure from interpersonal relationship, in a multidimensional model of schizotypy and to determine the psychometric properties of the Turkish version of Chapman's Revised Social Anhedonia Scale (SAS) in a non-clinical sample. Methods: Second-grade students of Ankara University Medical Faculty were recruited (n=266, Mage=20.28). Confirmatory factor analysis was performed to test schizotypy dimensions. The Cronbach's alpha internal consistency value, test-retest reliability and congruent validity of SAS were calculated. Results: The model in which social anhedonia was allowed to load on both schizotypy dimensions fit the data set better than the model in which social anhedonia was allowed to load on negative dimension alone. The internal consistency assessed with Cronbach's alpha was .84, test-retest reliability was r=.76 and the congruent validity of SAS was r=.55. Conclusion: The results of current study were consistent with those of earlier studies showing that social anhedonia was related to both schizotypy dimensions. Furthermore, the psychometric properties of the Turkish Version of SAS revealed that it is a reliable and valid measurement to assess social anhedonia in a non-clinical population.Publisher's Versio

Genotype and Allele Frequency of CYP3A4-392A > G in Turkish Patients with Major Depressive Disorder

OZEL-KIZIL, ERGUVAN TUGBA/0000-0001-9657-1382; ozguven, halise/0000-0002-9355-2757; Suzen, Sinan/0000-0003-1779-5850WOS: 000438973100013PubMed: 32454661Objectives: Genetic polymorphisms may help for individualized drug dosing and improved therapeutics. CYP3A4 is responsible for the metabolism of more than 50% of the commonly used drugs and metabolizes typical antipsychotic medications and antidepressant drugs. The objective of the study was to assess the genotype and allele frequencies of CYP3A4 -392A>G in Turkish patients with major depressive disorder receiving any SSRIs and to compare these results with the frequencies of other ethnic groups. Materials and Methods: Genotyping analyses of CYP3A4 -3921>G was conducted on 84 Turkish patients using the PCR-RFLP technique. Results: The allele frequencies were found as 0.982 (A) and 0.018 (G) for CYP3A4 -392A>G. The genotype frequencies were determined as 0.976 (AA), 0.012 (AG), and 0.012 (GG). The genotype frequencies were consistent with the Hardy-Weinberg equilibrium. Conclusion: The genotype and allele frequencies of CYP3A4 -392A>G were determined to be low in Turkish patients with major depressive disorder receiving SSRIs. Furthermore, the results of the study were compared with those of other ethnic groups and they displayed pronounced differences among other ethnic groups, especially black subjects.Scientific and Technological Research Council of TurkeyTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [109S147]This work was supported by the Scientific and Technological Research Council of Turkey (Project: 109S147)

ozguven, halise/0000-0002-9355-2757; Suzen, Sinan/0000-0003-1779-5850; OZEL-KIZIL, ERGUVAN TUGBA/0000-0001-9657-1382WOS: 000374326900029PubMed: 26830411Background Genetic polymorphisms in CYP2B6 and CYP2C19 may cause variability in the metabolism of sertraline, a widely used antidepressant in major depressive disorder treatment. Objective This study investigates the impact of CYP2B6*4 (785A > G), CYP2B6*9 (516G > T), CYP2B6*6 (516G > T + 685G > A) CYP2C19*2 (685G > A), CYP2C19*17 (-3402C > T) polymorphisms on plasma concentrations of sertraline and N-desmethyl sertraline in major depression patients treated with sertraline [n = 50]. Setting Participants were patients who admitted to an adult psychiatry outpatient unit at a university hospital. These were DSM-IV major depression diagnosed patients with a stable sertraline medication regimen [for at least one month]. Methods CYP2B6*4 (rs 2279343; 785A > G), CYP2B6*9 (516G > T; rs 3745274), CYP2B6*6 (516G > T + 685G > A) CYP2C19*2 (rs 4244285; 685G > A), CYP2C19*17 (rs 11188072; -3402C > T), polymorphisms were analyzed by polymerase chain reaction and restriction fragment length polymorphism. Plasma concentrations were measured by high-performance liquid chromatography in patients treated with SERT. Main outcome measure The distribution of CYP2B6*4, *6, *9 and CYP2C19*2, *17 among patient group and the association between genotype and sertraline metabolism. Results Sertraline, N-desmethyl sertraline, N-desmethyl sertraline/sertraline and dose-adjusted plasma concentrations were statistically compared between individuals with wild-type and variant alleles both for CYP2B6 and CYP2C19 enzymes. The mean N-desmethyl sertraline/sertraline value, was significantly lower in all subgroups with *6 and *9 variant alleles (p < 0.05). Sertraline/C values were significantly higher (p < 0.05) and N-desmethyl sertraline/C values were lower in all subgroups with *6 and *9 variant alleles compared to wild-type subgroup. Conclusion CYP2B6*6 and *9 variant alleles had a significant decreasing effect on sertraline metabolism in major depression patients which might result as variations in sertraline therapy

Hyperfocusing as a dimension of adult attention deficit hyperactivity disorder

Patients with Attention Deficit Hyperactivity Disorder (ADHD) suffer not only from inability to focus but also from inability to shift attention for events that trigger their interests. This phenomenon is called ``hyperfocusing{''}. Previous literature about hyperfocusing is scarce and relies mainly on case reports. The study aimed to investigate and compare the severity of hyperfocusing in adult ADHD with and without psycho-stimulant use. ADHD (DSM-IV-TR) patients either psycho-stimulant naive (n = 53) or on psycho-stimulants (n = 79) from two ADHD clinics were recruited. The control group (n = 65) consisted of healthy university students. A socio-demographic form, the Beck Depression Inventory, the Wender-Utah Rating Scale, the Adult ADHD Self- Report Scale and the Hyperfocusing Scale were applied to the participants. There was no difference between total Hyperfocusing Scale and Adult ADHD Self-Report Scale scores of two patient groups, but both have higher scores than controls (p < 0.001). Hyperfocusing is higher in adult ADHD and there was no difference between stimulant-naive patients or patients on stimulants. Hyperfocusing can be defined as a separate dimension of adult ADHD.
