The predictive factors for perceived social support among cancer patients and caregiver burden of their family caregivers in Turkish population.

OBJECTIVES: We aimed to identify the predictive factors for the perceived family social support among cancer patients and caregiver burden of their family caregivers. METHODS: Participants were 302 cancer patients and their family caregivers. Family social support scale was used for cancer patients, burden interview was used for family caregivers.All subjects also completed Beck depression invantery. The related socio-demographical factors with perceived social support (PSS) and caregiver burden were evaluated by correlation analysis. To find independent factors predicting caregiver burden and PSS, logistic regression analysis were conducted. RESULTS: Depression scores was higher among patients than their family caregivers (12.5 vs. 8). PSS was lower in depressed patients (p < .001). Family caregiver burden were also higher in depressive groups (p < .001). Among patients only the depression was negatively correlated with PSS (p < .001, r = -2.97). Presence of depression (p < .001, r = 0.381) was positively correlated and family caregiver role was negatively correlated (p < .001, r = -0.208) with caregiver burden. Presence of depression was the independent predictor for both, lower PSS for patients and higher burden for caregivers. CONCLUSIONS: The results of this study is noteworthy because it may help for planning any supportive care program not only for patients but together with their caregiver at the same time during chemotherapy period in Turkish population.

D-Cycloserine acts via increasing the GluN1 protein expressions in the frontal cortex and decreases the avoidance and risk assessment behaviors in a rat traumatic stress model.

D-cycloserine (DCS), an FDA approved anti-tuberculosis drug has extensively been studied for its cognitive enhancer effects in psychiatric disorders. DCS may enhance the effects of fear extinction trainings in animals during exposure therapy and hence we investigated the effects of DCS on distinct behavioral parameters in a predator odor stress model and tested the optimal duration for repeated daily administrations of the agent. Cat fur odor blocks were used to produce stress and avoidance and risk assessment behavioral parameters were used where DCS or saline were used as treatments in adjunct to extinction trainings. We observed that DCS facilitated extinction training by providing further extinction of avoidance responses, risk assessment behaviors and increased the contact with the cue in a setting where DCS was administered before extinction trainings for 3 days without producing a significant tolerance. In amygdala and hippocampus, GluN1 protein expressions decreased 72h after the fear conditioning in the traumatic stress group suggesting a possible down-regulation of NMDARs. We observed that extinction learning increased GluN1 proteins both in the amygdaloid complex and the dorsal hippocampus of the rats receiving extinction training or extinction training with DCS. Our findings also indicate that DCS with extinction training increased GluN1 protein levels in the frontal cortex. We may suggest that action of DCS relies on enhancement of the consolidation of fear extinction in the frontal cortex.

[ADHD in adult psychiatric outpatients: prevalence and comorbidity]. / Ayaktan psikiyatri hastalarinda dikkat eksikligi ve hiperaktivite bozuklugu: yayginlik ve estanilar.

AIM: This study aimed to investigate the prevalence of attention-deficit/hyperactivity disorder (ADHD) in adult psychiatric outpatients. Moreover, comorbid psychiatric diagnoses in adults with ADHD were determined. Patients with and without ADHD were compared regarding DSM Axis I-II comorbidity and sociodemographic characteristics. MATERIALS AND METHODS: The study included patients that presented for the first time to a psychiatric outpatient clinic during a 3-month period and were evaluated for adult ADHD. A sociodemographic form, Wender Utah Rating Scale, Turgay's Adult ADD/ADHD Evaluation Scale, Structured Clinical Interview I and II, Symptom Check List-90-R, and Beck Depression Inventory were administered. RESULTS: The study included 246 patients. Among the 39 patients diagnosed with ADHD, 25 were female (64.1%) and 14 were male (35.9%), and the mean age was 27.38 ± 8.3 years. The prevalence of ADHD in adult psychiatric patients was 15.9%. Adults with ADHD usually presented due to comorbid psychiatric problems; major depression (43%), generalized anxiety disorder (23%), and obsessive-compulsive disorder (17%) were the most common comorbid diagnoses. Substance abuse (58.9%) and attempted suicide (38.5%) were among the most prevalent psychiatric problems. CONCLUSION: The present findings show that ADHD is an important comorbidity in adult patients that present to psychiatric clinics, and may cause serious mental health problems or complicate mental illness.

The change in plasma GABA, glutamine and glutamate levels in fluoxetine- or S-citalopram-treated female patients with major depression.

OBJECTIVE: The aim of this study was to investigate the relationship between plasma glutamate, glutamine and gamma-aminobutyric acid (GABA) levels in female patients with major depression treated with S-citalopram or fluoxetine. METHODS: The patients were assigned into S-citalopram (10 mg/day) or fluoxetine (20 mg/day) groups (n = 15 per group). The Hamilton and Beck Depression Inventory Scales were performed on all study participants, and blood samples were collected. The same procedures were repeated 10 days following the onset of therapy. Fifteen female healthy volunteers were also included in the study for the evaluation of normal plasma levels. RESULTS: The plasma GABA levels of the healthy volunteers were higher whereas those for glutamate and glutamine were lower than the day zero samples of the patients. An increase in plasma GABA levels and a decrease in glutamate and glutamine levels were observed on the 10th day of treatment. No difference was detected between the drug treatments. CONCLUSION: Our findings may suggest that GABA, glutamate and glutamine play a role in depression and that plasma GABA may be used as a biomarker for treatment control.

Early maladaptive schemas activated in patients with obsessive compulsive disorder: A cross-sectional study.

Aim. The aim of the present article is to investigate the activation patterns of early maladaptive schemas (EMSs) in patients with obsessive-compulsive disorder (OCD). Method. During the time between 1 January 2006 and 1 April 2006, 45 consecutive patients from an outpatient facility of a general hospital and 45 age- and gender-matched healthy control subjects from the hospital staff were included in the study. They were administered the Structured Clinical Interview for Diagnosis of DSM-IV Mental Disorders (SCID-1), the Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-2), the Young Schema Questionnaire-Short Form (YSQ-SF), the Young Parenting Inventory (YPI) and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). The results were assessed using GraphPad Prisma V.3 statistical program. Results. The YSQ total score of the OCD group was significantly higher than the control group (t=3.62, P<0.0001). The average scores of the patients with OCD on certain schemas were significantly higher than the average scores of the control group, although the others did not make any difference between the OCD and control groups. Conclusion. The study demonstrates that, in the patients with OCD, most of the early maladaptive schemas including social isolation, vulnerability and pessimism, are prominently activated.
