Item Evaluation of Inflammation-Based Prognostic Risk Scores in Predicting in-Hospital Mortality Risk in Hospitalized COVID-19 Patients: A Cross-Sectional Retrospective Study(2023) Celik, Casit Olgun; Ozer, Nurtac; Ciftci, Orcun; Torun, Serife; Yavuz Colak, Meric; Muderrisoglu, Ibrahim Haldun; 0000-0002-6530-6153; 0000-0002-7190-5443; 0000-0002-0294-6874; 38633908; ABF-1652-2021; AAD-5477-2021; AAA-4360-2021Objective: Systemic inflammatory parameters are predictors of poor prognosis in COVID-19 patients. This study evaluated whether the prognostic nutritional index, which was also related to nutrition risk and other inflammation-based prognostic scores, was predictive of in-hospital mortality in COVID-19 patients.Materials and Methods: This was a retrospective cross-sectional single-center study. Based on the exclusion criteria, 151 patients over 18 years old diagnosed with COVID-19 and hospitalized in the intensive care unit between March 2020 and December 2020 were eligible for this study. Multivariable logistic regression analysis was performed to evaluate the predictive value of the Glasgow Prognostic Score (GPS), Prognostic Index (PI), Prognostic Nutritional Index (PNI), and Systemic Inflammatory Index (SII).Results: In the univariate analyses, age, diabetes mellitus (DM), chronic kidney disease, acute kidney injury, hypothyroidism, hospitalization stay, lactate dehydrogenase (LDH), as-partate aminotransferase (AST), D-dimer, ferritin, C-reactive protein (CRP), albumin, hemoglobin level, platelet count, urea, creatinine level, PNI, GPS were significantly associated with mortality. However, in the multivariable logistic regression analysis of the inflamma-tion-based prognostic scores, only PNI was statistically significant in predicting in-hospital mortality (OR=0.83; [95% CI=0.71-0.97]; p=0.019).Conclusion: PNI is a more useful and powerful tool among these inflammation-based prognostic risk scores in predicting in-hospital mortality in COVID-19 patients.Item Interobserver and Intermethod Variability in Data Interpretation of Breast Strain Elastography in Suspicious Breast Lesions(2021) Turnaoglu, Hale; Haberal, Kemal Murat; Arslan, Serdar; Yavuz Colak, Meric; Ulu Ozturk, Funda; Uslu, Nihal; https://orcid.org/0000-0002-0781-0036; https://orcid.org/0000-0002-8211-4065; https://orcid.org/0000-0001-7984-4326; https://orcid.org/0000-0002-0294-6874; https://orcid.org/0000-0003-2782-2824; 32950046; AAK-8242-2021; R-9398-2019; AAA-4360-2021; JCP-5266-2023Background/aim: Strain elastography has the disadvantage of being operator-dependent. Interobserver variability is observed during image acquisition and interpretation. This study aimed to analyze the interobserver and intermethod variability of strain elastography in image interpretation and evaluate the diagnostic performance combining elasticity score and strain ratio with ultrasonography. Materials and methods: A retrospective study was conducted on 70 breast lesions evaluated with B-mode ultrasonography and strain elastography. B-mode ultrasonography findings, elasticity scores, and strain ratio values were evaluated using static images by two radiologists. BI-RADS assessment of the lesions and the decision of both observers as to whether the biopsy was required using B-mode ultrasonography, and the combined ultrasonography+elasticity score, and the combined ultrasonography+elasticity score+strain ratio were compared with the histopathological results. Also, the interobserver agreement was analyzed for all the combinations. Results: There was very good agreement (weighted kappa = 0.865) between the observers for the elasticity scores. Very good agreement was observed between the observers for BI-RADS assessments using the combined ultrasonography+elasticity score and the combined ultrasonography+elasticity score+strain ratio (weighted kappa = 0.848, and 0.902, respectively). Area under the curve of B-mode ultrasonography, the combined B-mode ultrasonography+elasticity score, and the combined B-mode ultrasonography+elasticity score+strain ratio, were calculated as 0.859, 0.866, and 0.916 for observer 1, and 0.851, 0.829, and 0.916 for observer 2, respectively. There were no statistically significant differences between the observers' diagnostic performances in any of the combinations (P = 0.703, 0.067, and 0.972, respectively). Conclusion: In the evaluation and further assessment of breast lesions, semiquantitative strain ratio calculation may help improve diagnostic accuracy by reducing interpretational variety, when used together with B-mode ultrasonography and elasticity scoring, especially for inexperienced individuals.Item Cross-Sectional Analysis Of Tobacco Addiction In Hospitalized COVID-19 Patients(2022) Darilmaz Yuce, Gulbahar; Torun, Serife; Hekimoglu, Koray; Tuna, Derin; Sozbilici, Betul Rana; Cetin, Hikmet Oguz; Narlioglu, Mehmet Emin; Balli, Murat; Ozyesil, Ahmet Suheyl; Yavuz Colak, Meric; Ulubay, Gaye; Akcay, Muserref Sule; https://orcid.org/0000-0002-0805-0841; 36164949; AAD-9097-2021Introduction: The COVID-19 pandemic has become an important health issue with consequences for special populations since 2019. Tobacco use is an important public health issue and tobacco users are a risk group for lung infections.Materials and Methods: The aim of this study is to obtain information about disease prevalence and severity, laboratory parameters, and changes in radio-logical findings between smokers and non-smokers who were hospitalized, followed up, and treated for COVID-19, and to find answers to critical questi-ons regarding the response to antiviral and supportive therapy. Two hundred eighty-six patients who were hospitalized and treated between March 2020-February 2021 in the COVID-19 Isolation Ward of Baskent University Hospital were included in the study. The patients were grouped as current smokers, non-smokers, and ex-smokers. The groups were compared in terms of symptoms, laboratory findings, radiological findings, and treatment respon-se.Results: The median age of the patients included in the study was 59 (IQR= 32). Of the patients, 40.6% were female and 59.4% were male. In our study, we discovered that there were fewer female smokers (p< 0.001). When the current smokers (n= 56), non-smokers (n= 159), and ex-smokers (n= 71) were compared based on their findings, it was found that dyspnea was more common in current smokers (p= 0.009). Lung involvement was found to be more common (p= 0.002) and multifocal in the current smokers group (p= 0.038). The levels of oxygen saturation at the times of admission and discharge were lower in current smokers (p= 0.002 and p= 0.038). The need for nasal oxygen and noninvasive mechanical ventilation was also found to be higher in current smokers (p= 0.008 and p= 0.039). Systemic steroid requirement was higher in current smokers (p= 0.013). There was no statistically significant differen-ce in terms of mortality between current smokers, ex-smokers, and non-smokers (p= 0.662).Conclusion: The analysis of the findings of the patients hospitalized in the COVID-19 isolation ward indicated that COVID-19 leads to a more serious course in patients with a history of smoking.Item Predictors of burnout and distress in parents of children with autism spectrum disorder during COVID-19 home confinement(2023) Kaba, Duygu; Hasanli, Jamal; Yavuz Colak, Meric; Akin Sari, Burcu; 0000-0002-4261-8509; 0000-0003-1364-625X; 0000-0002-0294-6874; AAJ-8113-2021; AAA-4360-2021The study's purpose was to investigate the mental health and related variables of parents with an autism spectrum disorder (ASD) child during COVID-19 home confinement. The study data is based on the evaluation of online self-report questionnaires that assess parental distress, burnout, and coping levels, as well as parent-proxy reports of autism severity and related behavioral issues, as described by the parents of 79 children with ASD and their 83 typically developing age- and sex-matched opponents. The burnout and adaptive coping levels of the parents with ASD children were greater than those of the controls. However, there was no significant difference in terms of general distress levels. Increased irritability was the most commonly reported symptom among children with ASD. However, behavioral issues in children were the strongest predictor of parental burnout, whereas maladaptive coping skills were linked to general distress. This study emphasizes the significance of treating the behavioral issues of children with ASD and the coping strategies of their parents for the mental well-being of this vulnerable population and their parents during home confinement.
