Quality of sleep and quality of life in renal transplantation patients.

INTRODUCTION: Sleep and sleep-related disorders are common among end-stage renal disease patients. In the general population and hemodialysis patients, insomnia impairs health-related quality of life (HRQOL). The aims of this study were to examine the prevalence of sleep problems among renal transplantation patients and the relationship between the quality of sleep and the HRQOL. METHODS: Pittsburgh Sleep Quality Index (PSQI) for measuring quality of sleep, WHOQOL-BREF for quality of life, and Beck Depression Inventory (BDI) were applied to 100 renal transplant patients. RESULTS: Thirty (30%) subjects were "poor sleepers" (global PSQI > 5). Poor sleepers were younger (mean age: 31 vs 37); less educated (mean years of education: 7.80 vs 9.55), and more depressed (mean BDI scores 13.63 vs 7.18). There were significant inverse correlations between global PSQI and physical health (r = -0.31; P < .001) and psychological state (r = -.20; P = .04) with a significant correlation with BDI scores (r = .36; P < .001). The BDI score (P < .001) was the only significant factor of physical health, psychological state, and social functioning. BDI score (P < .001) and education (P < .022) were significant predictors of environmental conditions. CONCLUSION: Sleep problems are not as common among transplant as dialysis patients, but still higher than the general population. Poor sleep seems to be a part of depressive symptomatology. Severity of depression and lower education were more negatively effective factors on the quality of life of these patients than the quality of sleep.

Anxiety, depression and stressful life events among medical students: a prospective study in Antalya, Turkey.

OBJECTIVE: To assess psychological changes in medical students in Antalya, Turkey during their undergraduate education. The first-year follow-up outcomes are presented in this article. DESIGN: All first-year undergraduate students were given a detailed, self-report questionnaire and another in the second year. They were asked to complete the General Health Questionnaire (GHQ), the Spielberger State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI). SETTING: The Faculties of Medicine, Economics and Physical Education (PE) of the Akdeniz University, Antalya, Turkey. PARTICIPANTS: All first-year undergraduate students in the Faculties of Medicine, Economics and PE who were registered in 1996. RESULTS: The findings showed that psychological test scores on the GHQ, the STAI and the BDI rose significantly in medical students between the first and second years. Using the GHQ, with different cut-off scores, the percentage of students scoring above the thresholds was higher in medical students in year 2, compared with economics and PE students. In addition, the scores for some stressful life events of medical students showed a significant rise from year 1 to year 2. Multiple regression analyses indicated that some stressful life events related to social activities were associated with the psychological test scores for medical students. CONCLUSION: The results indicate that there is a decrease in the psychological health of first-year medical students. Some inadequacies in the social activities of the students might play a role in this type of disturbance.

Is the efficacy of topical corticosteroid therapy for psoriasis vulgaris enhanced by concurrent moclobemide therapy? A double-blind, placebo-controlled study.

BACKGROUND: Psychosocial factors have been implicated in the onset and exacerbation of psoriasis. OBJECTIVE: We conducted a randomized, placebo-controlled, double-blind study to investigate the effect of an antidepressant agent, moclobemide, on the course of psoriasis vulgaris. METHODS: Sixty subjects were enrolled in the study. Patients were randomly assigned to treatment groups. Patients received moclobemide 450 mg/day or placebo and a topical corticosteroid ointment (diflucortolone valerate) for 6 weeks. Patients were examined at the beginning of the study and at 2-week intervals. At each visit, the severity of psoriasis and psychologic status were evaluated with the Psoriasis Area Severity Index (PASI), Beck Depression Inventory (BDI), Hamilton Rating Scale for Anxiety (HAM-A), Hamilton Rating Scale for Depression (HRS-D-17) and State-Trait Anxiety Inventory including state (STAI-1) and trait anxiety (STAI-2). RESULTS: Treatment efficacy was able to be evaluated in 22 patients in the moclobemide-treated group and in 20 in the placebo-treated group. The improvement rates in PASI, BDI, STAI-1, and HAM-A scores were significantly higher in the moclobemide treatment group. The level of state anxiety was diminished in the moclobemide group. Correlation was positive between improvement rates of the psoriatic lesions and state anxiety in all patients. CONCLUSION: Our results suggest that an antidepressant drug is useful in the treatment of psoriasis.

Bereitschaftpotential in schizophrenia.

BACKGROUND: Several reports have documented the presence of motor abnormalities in schizophrenic patients. METHOD: Thirty schizophrenics and 28 healthy controls were included in the study. Scalp-recorded bereitschaftpotentials (BPs) generated prior to voluntary movements were recorded in all subjects. RESULTS: The early (NSI) and late components of BP and peak negativity were reduced in all schizophrenic patients. In particular, the NSI was reduced in patients with positive symptoms, and the late component in patients with negative symptoms. CONCLUSIONS: These findings provide further support of the involvement of frontal cortex, subcortical structures and their connections in schizophrenia, and highlight some differences between positive and negative symptom clusters.
