ABSTRACT

The aim of this study was translating and exploring psychometric properties of Serbian Pittsburgh Sleep Quality Index (PSQI) in a sample of "good" and "bad" sleepers suffering from depression or obstructive sleep apnea (OSA). Formal translation and validation were performed on a sample of healthy controls, patients with untreated OSA, and with diagnosed major depressive disorder with evaluation of internal consistency, test-retest reliability, and construct and criterion validity. Controls and OSA subgroups were recruited from a larger sample of commercial drivers. One hundred and forty subjects, 84.3% male, 22-67 years old, were included. OSA subgroup had 59 subjects and depression subgroup had 40 subjects (22 females). Mean ± SD total PSQI was 3.5 ± 2.2 in controls, 4.9 ± 3.6 in OSA subjects, and 9.0 ± 4.9 in patients with depression. Cronbach's α for total PSQI was 0.791. Subscale scores were significantly correlated to global PSQI in all subgroups. Intraclass correlation coefficient for global PSQI was 0.997 ( p < .001). Epworth Sleepiness Scale score was significantly correlated to global PSQI (ρ = 0.333, p < .001). Three subgroups differed significantly in total PSQI and PSQI ≥ 5, even after adjustments for age and gender ( p < .001). OSA patients had higher mean PSQI than controls but not significantly ( p = .272). PSQI-reported sleep latency did not correlate with PSG-measured sleep latency ( r = .130, p = .204). Total PSQI was significantly correlated to OSA severity (ρ = 0.261, p < .05). Serbian PSQI showed good internal consistency, test-retest reproducibility, and adequate construct and criterion validity, which supports further exploration of its use as a sleep quality screening tool in different target populations.

ABSTRACT

INTRODUCTION: Ovarian cancer is one of the leading health problems, as it is the underlying cause of disease and deaths of a large number of women around the world. Postmenopausal female population, in whom ovarian carcinoma is most often diagnosed in advanced stages of the disease, is primarily affected. MATERIAL AND METHODS: We used data from Hospital Registry for Malignant Neoplasms at Oncology Institute of Voijvodina for the period from 2001 to 2008, according to which 422 cases of ovarian carcinoma were reported. The obtained data were classified into three groups according to FIGO classification of ovarian malignant neoplasms. The statistical assessment of data employed the method of linear trend and tests of statistical significance (t-test). RESULTS: The results of our study showed that most cases of diagnosed disease were advanced forms of ovarian cancer, FIGO stages II and IV. The linear trend of the reported cases in stage 1 for the period 2001/2008 showed a descending trend. According to the processed data, in the same period of time, stage II showed an ascending trend, while stages III and IV described together showed a moderate ascending linear trend. CONCLUSION: A vast majority of cases of ovarian cancer are detected in advanced stages of the disease, which is at the same time the group with the worst prognosis. Special attention should be paid to the group of patients with positive family history, as well as the presence of BRCA 1 and BRCA 2 genetic mutations. Currently existing diagnostic procedures have not given good results individually in terms of high sensitivity for diagnosis of early stages.
