    Objective: This study aimed to investigate the prognostic value of viral load detected in the saliva of COVID-19 patients in the early stage of infection. Study design: Oro-nasopharyngeal swab and saliva samples were collected from all patients simultaneously in the early stage of COVID-19. Viral loads were determined by extracting viral RNAs from saliva samples of patients whose ONP swabs were positive for SARS-CoV-2 by RT-qPCR. The demographic information, comorbidities, cycle threshold values, and one-month clinical courses were recorded and compared. Results: The patients' clinical course was evaluated for one month; 56 % of patients had mild disease, 26.4 % had moderate disease, 9.6 % had severe disease, and 8% had a critical/mortal disease. The average cycle threshold values of SARS-CoV-2 in saliva and ONP samples were measured as 22.28 and 24.19, respectively. Cycle threshold value of saliva was found to be significant in predicting disease severity (Eta coefficient 0.979). A statistically significant relationship was found between the disease's severity and the mean of ONP samples' Ct-values (p < 0.05). Gender, age, body mass index, and co-morbidities were compared with the severity of the disease; no statistically significant difference was found. Conclusion: Viral load detected in saliva in the early period of COVID-19 infection may have a prognostic value in showing the disease's course in patients over 45-year-old. Saliva is an easily obtainable, reliable material for COVID-19 screening.

    The relationship between anxiety, depression, daytime sleepiness in the REM-related mild OSAS and the NREM-related mild OSAS
    (Geckil, Aysegul Altintop, 2020) Ermis, Hilal; Altintop Geckil, Aysegul
    Introduction: Obstructive sleep apnea syndrome (OSAS) is a common form of sleep-related respiratory disease characterized by recurrent blockages in the upper airway. Rapid eye movement (REM)-related OSAS is a condition in which apneas and hypopneas are more common during REM sleep. We investigated whether there was any difference between REM-related mild OSAS group and NREM-related mild OSAS group in terms of anxiety, depression, and daytime sleepiness. Methods: A total of 166 patients with mild OSAS (72 patients with REM-related and 94 NREM-related OSAS) participated in the study. Hospital Anxiety-Depression Scale (HADS) and Epworth Sleepiness Scale (ESS) questionnaires were completed by both groups. Results: Anxiety and depression scores were significantly higher in patients with REM-related OSAS in comparison to the NREM-related OSAS group (p = 0.01, p = 0.02 respectively). There was no statistically significant difference between the two groups in terms of ESS scores (p = 0.60). Conclusion: The results of our study suggest that patients with REM-related OSAS have higher rates of depression and anxiety compared to non-REM-related OSAS patients and this may adversely affect quality of life. It may be possible to prevent psychiatric complications, such as depression and anxiety, by administering treatments that reduce REM sleep duration and intensity in patients with REM-related OSAS.
