Uygur Omer Faruk,Bahar Aynur 대한수면학회 2023 sleep medicine research Vol.14 No.1

Background and Objective We aimed to investigate the mediating role of bedtime procrastination in the relationship between sleep effort and insomnia severity in this study.Methods We included 497 university students in this study. All the participants completed the sociodemographic data form, Glasgow Sleep Effort Scale (GSES), Insomnia Severity Index (ISI), Depression-Anxiety-Stress Scale-21 (DASS-21), and Bedtime Procrastination Scale (BPS). We divided the participants into groups, according to their GSES and BPS scores, those with high-low sleep effort and those with BP (+) and BP (-), respectively. We compared the variables in these groups. Finally, we analyzed the mediating role of bedtime procrastination in the relationship between sleep effort and insomnia severity.Results The mean age of the participants was 20.41 ± 1.83 years. ISI, BPS, and DASS-21 were statistically significant in the group with high sleep effort (p < 0.01). Among the psychometric instrument scores, the highest correlation with GSES was with ISI, and then there was a statistically significant positive correlation with DASS-21. In addition, there was a statistically significant positive correlation between GSES and BPS. Bedtime procrastination played a partial mediation role in the relationship between sleep effort and insomnia severity.Conclusions Bedtime procrastination partially mediated the relationship between sleep effort and insomnia severity. Therapists should consider sleep effort and bedtime procrastination on their agenda in cognitive behavioral therapy sessions for insomnia.

Serhat Aydoğan,Uygur Er,Onur Özlü 대한척추외과학회 2014 Asian Spine Journal Vol.8 No.2

Study Design: A randomized prospective study. Purpose: To assess postoperative analgesic requirements after Phyback therapy preemptively in patients undergoing lumbar stabilization. Overview of Literature: Frequency Rhythmic Electrical Modulation System is the latest method of preemptive analgesia. Methods: Forty patients were divided into two groups. Patients who were to receive tramadol were allocated to “group A” and those who were to receive Phyback therapy were allocated to “group B.” In patients with a visual analog scale score of >4 or a verbal rating scale score of >2, 75 mg of diclofenac IM was administered. The amount of analgesic consumption, the bolus demand dosage, and the number of bolus doses administered were recorded. Patient satisfaction was evaluated using the visual analog patient satisfaction scale. Results: There were statistically significant differences in the visual analog scale and verbal rating scale scores in the fourth, sixth, 12th, and 24th hours. The number of bolus infusions was significantly lower in group B. The amount of analgesic consumption was higher in group A. There was a significant difference between the two groups in the number of bolus infusions and the total amount of analgesic consumption, and this comparison showed better results for group B. Conclusions: Application of Phyback therapy reduced postoperative opioid consumption and analgesic demand, and it contributed to reducing patients’ level of pain and increased patient satisfaction. Moreover, the application of preemptive Phyback therapy contributed to reducing preoperative pain which may have reduced patient anxiety.

Objective Society’s sleep-wake cycle and eating behaviors have altered and are considered the psychological outcomes of the coronavirus disease-2019 (COVID-19) pandemic. Our aim was to examine the relationship between sleep-wake rhythms, eating behaviors (dieting, oral control, and bulimic behaviors), and attention deficit hyperactivity disorder (ADHD) symptoms with weight gain during the COVID-19 pandemic.Methods The participants were 578 female university students divided into three groups based on weight change during COVID-19 who lost weight, whose weight did not change (nWC), and who gained weight (WG). The participants’ information about weight change in the last year and responses to the Pittsburg Sleep Quality Index, Eating Attitudes Test, Adult ADHD Severity Rating Scale, and Wender Utah Rating Scale were collected via an online survey from January 8, 2021 to January 11, 2021.Results The sleep-wake phase was more delayed in WGs than in the other two groups. The bulimic behavior score was higher and the oral control behavior score was lower in the WG group than in the nWC group. A hierarchical regression analysis model, in which weight change scores were dependent variables, showed that mid-sleep time in second step (β=4.71, t=2.18, p=0.03), and oral control (β=-0.11, t=-3.24, p=0.001)/bulimic behaviors (β=0.20, t=3.20, p=0.001) in third step were associated with weight change after controlling for both current and childhood ADHD symptoms.Conclusion Chronotherapeutic approaches that regulate sleep-wake rhythm may facilitate weight control of individuals during stressful periods, such as the COVID-19 outbreak.

Original Article : Asymptomatic Brain Lesions on Cranial Magnetic Resonance Imaging in Inflammatory Bowel Disease

( Can Dolapcioglu ),( Yuksel Guleryuzlu ),( Oya Uygur Bayramicli ),( Emel Ahishali ),( Resat Dabak ) 대한간학회 2013 Gut and Liver Vol.7 No.2

Background/Aims: This study aimed to examine the frequency and type of asymptomatic neurological involvement in inflammatory bowel disease (IBD) using cranial magnetic resonance imaging (MRI). Methods: Fifty-one IBD patients with no known neurological diseases or symptoms and 30 controls with unspecified headaches without neurological origins were included. Patients and controls underwent cranial MRI assessments for white matter lesions, sinusitis, otitis-mastoiditis, and other brain parenchymal findings. Results: The frequencies of white matter lesions, other brainstem parenchymal lesions, and otitis-mastoiditis were similar in IBD patients and controls (p>0.05), whereas sinusitis was significantly more frequent in IBD patients (56.9% vs 33.3%, p=0.041). However, among those subjects with white matter lesions, the number of such lesions was significantly higher in IBD patients compared to controls (12.75±9.78 vs 3.20±2.90, p<0.05). The incidence of examined pathologies did not differ significantly with disease activity (p>0.05 for all). Conclusions: The incidence of white matter lesions seemed to be similar in IBD patients and normal healthy individuals, and the lesions detected did not pose any clinical significance. However, long-term clinical follow-up of the lesions is warranted. (Gut Liver 2013;7:169-174)

Sleiman Jana,Cho Eulah,Lee Dongin,Cho Inn-Kyu,Chung Seockhoon,Uygur Omer Faruk 대한수면학회 2023 sleep medicine research Vol.14 No.1

Background and Objective We aimed to investigate whether viral anxiety affects insomnia severity in patients with insomnia disorder during the coronavirus disease 2019 (COVID-19) pandemic. In addition, we examined whether viral anxiety mediates the influence of dysfunctional beliefs about sleep on insomnia severity.Methods The medical records of 111 patients who visit the sleep clinic from September 2021 to May 2022 were reviewed. Patients’ symptoms were rated with rating scales including Insomnia Severity Index (ISI), Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Dysfunctional Beliefs and Attitudes about Sleep-16 items (DBAS-16), Patient Health Questionnaire-9 items (PHQ-9), Epworth Sleepiness Scale, and discrepancy between desired time in bed and desired total sleep time (the DBST index).Results The SAVE-6 score was not significantly correlated with ISI score among insomnia patients. Linear regression analysis showed that the ISI score was expected by PHQ-9 (β = 0.21, p = 0.038) and DBAS-16 (β = 0.42, p < 0.001). Mediation analysis showed that viral anxiety did not mediate the influence of dysfunctional beliefs about sleep on insomnia severity.Conclusions We could not observe the mediating effect of viral anxiety on the association between dysfunctional beliefs about sleep on insomnia severity. Though COVID-somnia was one of big issues in this COVID-19 pandemic, the influence of virus on the severity of insomnia among insomnia patients needs to be interpreted cautiously.

Influence of gas exhaust geometry on flow pattern, performance, and erosion rate of a gas cyclone

Parvaz Farzad,Hosseini Seyyed Hossein,Bastan Ahmad Reza,Foroozesh Jamal,Babaoğlu Nihan Uygur,Elsayed Khairy,Ahmadi Goodarz 한국화학공학회 2023 Korean Journal of Chemical Engineering Vol.40 No.7

The effect of gas exhaust shape on the performance, flow pattern, and erosion rate of a gas cyclone was investigated using a numerical model. The results show that the shape of the gas exhaust affects the movement of the vortex core in the gas cyclone. With a change in the shape of the exhaust gas, the axial and tangential velocities changed in the cyclone. The highest turbulent kinetic energy in cyclones was found in the gas exhaust region. The results showed that the diamond gas exhaust exhibited the highest turbulent kinetic energy among the other shapes. In the cases of diamond and square gas exhausts, the size of the Rankine vortex was decreased, leading to a reduction in the centrifugal force of the gas flow and, thereby, cyclone separation efficiency. The lowest erosion rate and highest separation efficiency were found for the cyclone with a circular gas exhaust.

To date, there was no controlled-study regarding awareness and knowledge of colorectal cancer in the Turkish population. We therefore designed a questionnaire consisting of items related to socio-demographic parameters, medical and family history and questions of awareness and knowledge about colorectal cancer for use in a descriptive cross-sectional study. An interviewer-administered technique was applied and 450 subjects were interviewed in the outpatient clinics at Near East University Hospital. Among all subjects, 337 were found to be eligible for the study group. Exclusion criteria were age below 18 years, any cancer history, family history of colorectal cancer, current colorectal problems, history of any diagnostic or therapeutic interventions for colorectal diseases. All participants stated that they heard about colorectal cancer. When asked about the lifetime risk of colorectal carcinoma, only 25.4% of women and 37.9% of men estimated correctly. Univariate analysis revealed that the total awareness score was significantly correlated with age, marital status, parenthood and fecal occult blood testing history. On multivariate analysis of independent predictors for awareness of colorectal cancer were found to be history of fecal occult blood testing, age and marital status were found to be the most important determinants. As a conclusion, opportunistic screening with fecal occult blood test by physicians from non-gastrointestinal specialties not only helps to reduce the mortality but also increases the awareness of colorectal cancer.
