Item Physical Activity, Anxiety, Depression, And Coping In Turkish Men And Women During The First Wave Of COVID-19(CADERNOS DE SAUDE PUBLICA, 2024-06-29) Filiz, Bijen; Ozyol, Funda Coskun; Guven, Bengu; Korur, Ezel Nur; Yuksel, Yilmaz; Yavuz, Cavit Isik; Ding, Kele; Yang, Jingzhen; Durstine, Larry; Chin, Ming -kai; Demirhan, GiyasettinA need exists to better understand the relationships between COVID-19, coping behaviors, physical activity and stress, and COVID-19's impact on way of life. A cross-sectional study design was used to examine adult physical activity, hope, depression, anxiety, and coping status by gender during the COVID-19 pandemic, and to determine the impact of these variables on the coping process. The study also examined the effect of gender on the relation between physical activity and dependent variables. A global survey instrument was used in this study, including 1,400 Turkish adults. This study identified significant gender-based differences regarding physical activity, hope, depression, anxiety, and coping status of adults, although no significant genderbased difference was found regarding hope scores. Furthermore, physical activity directly influenced coping (beta = 0.10), hope (beta = 0.12), and anxiety (beta = -0.08). Hope directly and positively influenced coping (beta = 0.45) and directly and negatively influenced anxiety (beta = -0.25) and depression (beta = -0.28). Moreover, gender did not directly affect physical activity, but it was associated with decreased coping and increased depression and anxiety. Finally, gender had no effect on the relation between physical activity and hope, coping, depression, and anxiety (p > 0.01). These outcomes support the critical importance of physical activity and hope when coping with COVID-19 regardless of gender.Item Challenges Of Masked Communication In Healthcare And Facilitating Strategies(JOURNAL OF PSYCHIATRIC NURSING, 2024-07-22) Demirel, YukselWearing a face mask is one of the main means of preventing the transmission of certain respiratory diseases. This measure, combined with social distancing and hand washing, helps to slow the spread and reduce transmission of the virus, especially among people who are expressed as asymptomatic carriers, while causing communication difficulties between patients and healthcare professionals. If strategies to cope with these difficulties are not developed, serious errors may occur in the field of health services. Because the field of health services is one of the service areas where it is vital to maintain communication without interruption. For this reason, the effective performance of the procedures requires that the health personnel understand the messages correctly and appropriately both in their communication with each other and with the patient and that the patients can adequately express their feelings and thoughts to the healthcare professionals. The aim of this study is to reveal the difficulties and facilitating strategies of masked communication in health services during the COVID-19 process. The method of "document scanning-a literature review" was used as a way of data collection in the research. In this direction, the literature dealing with the importance of the face in expressing emotions in face-to-face communication and the difficulties caused by face masks in communication during the COVID-19 epidemic was scanned using keywords and various combinations of these words.Item The Relationship Between Burnout And Work Engagement Levels Of Nurses And Physiotherapists Working During The Covid-19 Pandemic Period(WORK-A JOURNAL OF PREVENTION ASSESSMENT & REHABILITATION, 2024) Gulsen, Mustafa; Ertugrul, Bekir; Taskin, Gulsen; Aytar, Ayca; Genc, Yasemin KavuncubasiBACKGROUND: The COVID-19 pandemic has affected all health professionals worldwide. This has also influenced their working lives, affecting burnout and work engagement. OBJECTIVE: This study aims to investigate the relationship between burnout and work engagement among nurses and physiotherapists during the COVID-19 pandemic. METHODS: This cross-sectional study was conducted with total 509 nurses and physiotherapists who were working at any of the private, public, or university hospitals from two large and one small cities. A Personal Introduction Form, the Maslach Burnout Scale, and the Work Engagement Scale were used in the study. Frequency, percentage, mean, and Pearson correlation analysis were used for statistical analysis. Necessary ethical approvals were taken for the research. RESULTS: There was a significant, moderate, negative relationship between the average scores of the nurses on the vigor and devotion dimensions and the Work Engagement Scale and their average scores on emotional exhaustion, personal accomplishment, depersonalization dimensions and their average score on the Maslach Burnout Scale (p < 0.05). There was a significant, moderate, negative relationship between the scores of the physiotherapists on the Work Engagement Scale and its dimensions and their average scores on the Maslach Burnout Scale and its dimensions (p < 0.05). CONCLUSION: In our study, it was found that the burnout levels of nurses and physiotherapists had an effect on their work engagement during the COVID-19 pandemic. During and after the COVID-19 process, managers should take measures to reduce the burnout levels of health professionals and increase their level of work engagement.Item Diyabet tedavisinde kullanılan ilaçların covıd-19 enfeksiyonuna etkilerinin retrospektif olarak araştırılması(Başkent Üniversitesi Tıp Fakültesi, 2023) Saraçoğlu, Yaşar Ozan; Turhan İyidir, Özlemİlk kez Aralık 2019 tarihinde tespit edilen yeni bir koronavirüs olan SARS-CoV-2 etkeninin sebep olduğu COVID-19 hastalığı tüm dünyada pandemiye sebep olmuştur. Hastalık özellikle ileri yaş ve ek hastalıkları olan popülasyonda ciddi morbidite ve mortalite sebebidir. Yapılan bu retrospektif çalışmada tip 2 diyabet tedavisinde kullanılan ilaçların COVID-19 enfeksiyonuna etkilerinin incelenmesi amaçlanmıştır. Çalışmada Başkent Üniversitesi Ankara Hastanesi Endokrinoloji ve Metabolizma Hastalıkları Bilim Dalı Merkez ve Ümitköy polikliniklerine, Türkiye'de pandeminin başlangıcı olarak kabul edilen 11 Mart 2020 ile 31 Temmuz 2021 tarihleri arasında başvuran tip 2 diyabet tanısı bulunan 6430 hastadan çalışmaya dahil edilme kriterlerini karşılayan 431 vaka incelenmiştir. Hastalık şiddeti, hastaların demografik, klinik, laboratuvar özellikleri; COVID-19 sebebi ile hastane yatış ihtiyacı, yoğun bakım ünitesinde takip ihtiyacı, mekanik ventilasyon ihtiyacı olup olmaması, COVID-19 hastalığı öncesi, hastalık sırasında ve sonrasında kullandıkları antidiyabetik ilaç grupları, COVID-19 aşı türü incelenmiştir. Tip 1 diyabet tanısı olanlar, gestasyonel diyabet tanısı olanlar, yeni tanı konulan diyabet hastaları veya başvurudan önce 6 ay içinde diyabet tanısı konulmuş hastalar, diyabet tanısı konulduğu halde ilaç kullanmayanlar ve son 6 ay içerisinde ilaç tedavisinde değişiklik olanlar çalışma dışı bırakılmıştır. Ayrıca, Başkent Üniversitesi medikal bilgi sisteminde verileri yetersiz olan veya telefonla ulaşılamayanlar ve e-Nabız verilerine ulaşılamayanlar veya bu verilere ulaşılması için rıza göstermeyen hastalar da çalışma dışı bırakılmıştır. Sülfonilüre tedavisi alanların %48'inde dispne görülürken, almayanların %23'ünde dispne saptandı (p=0,010). Dispne için çoklu lojistik modelinde, sülfonilüre ve HbA1c düzeyi değişkenleri analiz edilmiştir. Çoklu lojistik regresyon analizi sonucunda sadece sülfonilüre değişkeni anlamlı bulunmuştur. Dispne riski; sülfonilüre kullananlarda kullanmayanlara göre 3,146 kat fazladır. Çalışmamızda anti-diyabetik ilaç gruplarının hastalık seyrine veya ağırlığına olumlu ya da olumsuz bir etkisi olmadığı gösterilmiştir. Yalnızca enfeksiyon sırasında, sülfonilüre grubu ilaçların daha dikkatli kullanılmasını, gerektiğinde doz azaltılmasını veya kesilmesini, bu kararın da hastanın iştah-oral alım durumu ve kan glikoz takibine göre verilmesi gerektiğini düşünüyoruz. Çalışmamızın konusu hala birçok açıdan aydınlatılmayı bekleyen, yeni çalışmalara ihtiyaç duyulan bir alan olup iyi tasarlanmış prospektif çalışmalar ile antidiyabetik ajanların COVID-19 kliniğinde olumlu ve olumsuz etkileri incelenmesine ihtiyaç duyulmaktadır. COVID-19 disease, caused by a new coronavirus, SARS-CoV-2, which was first detected in December 2019, has caused a pandemic all over the world. The disease has caused serious morbidity and mortality, especially in the population with advanced age and additional diseases. In this retrospective study, it was aimed to examine the effects of drugs used in the treatment of type 2 diabetes on COVID-19 infection. In the study, 431 cases meeting the inclusion criteria of 6430 patients with type 2 diabetes who applied to Başkent University Ankara Hospital Endocrinology and Metabolic Diseases Department Center and Ümitköy polyclinics between March 11, 2020, which is considered as the beginning of the pandemic in Turkey, and July 31, 2021, were examined. Disease severity, demographic, clinical and laboratory characteristics of patients; the need for hospitalization due to COVID-19, the need for follow-up in the intensive care unit, the need for mechanical ventilation, the antidiabetic drug groups used before, during and after the COVID-19 disease, the types, and doses of the COVID-19 vaccine, the short and long-term after recovery from the disease period complications were examined. Patients with a diagnosis of type 1 diabetes, those with a diagnosis of gestational diabetes, newly diagnosed diabetes patients, or patients who were diagnosed with diabetes within 6 months before admission, those who did not use medication despite being diagnosed with diabetes, and those who had a change in medication in the last 6 months were excluded from the study. In addition, patients with insufficient data in the Başkent University medical information system or those who could not be reached by phone, and those whose e-Nabız data could not be reached or who did not consent to access these data were also excluded from the study. While dyspnea was observed in 48% of those who received sulfonylurea treatment, 23% of those who did not receive it had dyspnea (p=0.010). In the multiple logistic model for dyspnea, sulfonylurea and HbA1c level variables were analyzed. As a result of multiple logistic regression analysis, only the sulfonylurea variable was found to be significant. risk of dyspnea; It is 3.146 times higher in sulfonylurea users than in non-users.In our study, it was shown that the antidiabetic drug groups did not have a positive or negative effect on the course or severity of the disease. We think that sulfonylurea drugs should be used more carefully only during infection, dose reduction or discontinuation when necessary, and this decision should be made according to the patient's appetite and oral intake status and blood glucose monitoring. The subject of our study is still a field that needs to be clarified in many ways and new studies are needed, and there is a need to examine the positive and negative effects of antidiabetic agents in the COVID-19 clinic with well-designed prospective studies.Item Re-Evaluation of Logistics Strategy During COVID-19 Pandemic Environment: Reduced Customer Service Commitment(2023) Kara, Ali; Spillan, John E.; Acikdilli, Gaye; Kirkbesoglu, Erdem; 0000-0002-6781-9753; ABI-3973-2020The Bowersox and Daugherty's (1987) typology has been tested in international markets, providing valuable insights into its relevance. However, the literature has yet to examine its effectiveness in business environments affected by pandemics. The purpose of this study is to empirically assess the resilience of the logistics strategy framework in an emerging market during the COVID-19 pandemic. To measure the three dimensions of the overall logistics strategy, as well as mediator variables such as logistics integration and customer service commitment, we collected 326 responses from logistics managers in Turkey. Using a structural equation model (SEM), we found that the three dimensions of the overall logistics strategy remained robust during the pandemic, thus supporting the durability of the Bowersox and Daugherty's (1987) framework. However, the customer service commitment was found to have a statistically insignificant role in mitigating the overall logistics strategy and the firm's competitive responsiveness.Item Evaluation of the COVID-19 Rapid Antigen Test(2023) Sanli, Ozlem Oguc; Kuscu, Ozlem Ozkan; Incekas, Caner; 0000-0001-7899-0233; 0000-0001-9019-423XIntroduction: Coronavirus disease, is an infectious disease caused by the SARS-CoV-2. The gold standard method to diagnose is the reverse transcriptase polymerase chain reaction test. Rapid antigen tests can also be used for diagnosis. This study aims to compare the results of these two methods.Materials and Methods: Between November 2021 and July 2022, the study included 1811 patients who visited the emergency depart-ment with coronavirus-related symptoms and signs. Respiratory samples from these patients were simultaneously evaluated using both reverse transcriptase polymerase chain reaction and rapid antigen tests. The reverse transcriptase polymerase chain reaction tests were conducted using the BioSpeedy SARS-CoV-2 reverse transcriptase polymerase chain reaction kit (Bioeksen-Turkiye), while the rapid antigen tests were performed using the RapidForTM SARS-CoV-2 Ag (Vitrosens-Germany).Results: The comparison of the reverse transcriptase polymerase chain reaction test and rapid antigen test results showed a 90.67% sensitivity, 98.28% specificity, 91.27% positive predictive value, 98.15% negative predictive value, and 97.02% (1757/1811) accuracy. Qualitative results of both tests exhibited a very good agreement (Kappa= 0.892, p< 0.001). According to the reverse transcriptase polymerase chain reaction test, the sensitivity of the rapid antigen test was found to be 100% in 28 samples with a cycle threshold <17, 100% in 78 samples with a cycle threshold <20, 98.33% in 120 samples with a cycle threshold <22, and 96.28% in 215 samples with a cycle threshold <25.Conclusion: When the results of the study are evaluated, it is seen that the use of the rapid antigen test for screening purposes and confirmation of patients with negative test results by Reverse transcriptase polymerase chain reaction will provide advantages in terms of both time and cost. Due to the low sensitivity and high positive predictive value of the vitrosens rapid antigen test, we think that this test can be used in the first stage to accelerate the diagnosis of patients with high viral load, who are more likely to be infectious, to prevent transmission and to start their treatment quickly.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 Which Sequence Should Be Used in the Thorax Magnetic Resonance Imaging of COVID-19: A Comparative Study(2023) Ates, Ayse sule; Yagdiran, Burak; Taydas, Onur; Faruk Ates, OmerBackground and aim: To evaluate and compare magnetic resonance imaging (MRI) sequences that could potentially be used in the diagnosis of coronavirus disease 2019 (COVID-19). Materials and methods: Included in the study were 42 patient who underwent thorax computed tomography (CT) for COVID-19 pneumonia and thorax MRI for any reason within 24 h after CT. The T2-weighted fast spin echo periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) (T2W-FSE-P), fast imaging employing steady-state acquisition, T2 fat-saturated FSE, axial T1 liver acquisition with volume acceleration (LAVA) and single-shot FSE images were compared in terms of their ability to show COVID-19 findings. Results: The mean age of the patients was 47.2 +/- 24 years. Of the patients, 22 were male (52.4%) and 20 (47.6%) were female. The interobserver intraclass coefficient (ICC) for the image quality score was the highest in the T2W-FSE-P sequence and lowest in the T1 LAVA sequence. All of the lesion-based evaluations of the interobserver agreement were statistically significant, with the kappa value varying between 0.798 and 0.998. Conclusion: All 5 sequences evaluated in the study were successful in showing the parenchymal findings of COVID-19. Since the T2W-FSE-P sequence had the best scores in both interobserver agreement and ICC for the image quality score, it was considered that it can be included in thorax MRI examinations to assist the diagnosis of COVID-19.Item Clinical Features of SARS-CoV-2 Infection in Patients Undergoing Solid-Organ Transplant: Baskent University Experience(2023) Yuce, Gulbahar Darilmaz; Ulubay, Gaye; Tek, Korhan; Bozbas, Serife Savas; Erol, Cigdem; Buyukasik, Piril; Haberal, Kemal Murat; Arslan, Ayse Hande; Akcay, Muserref Sule; Haberal, Mehmet; 0000-0002-2535-2534; 34635037; AAJ-1219-2021Objectives: The clinical features and treatment approaches, outcomes, and mortality predictors of COVID-19 in solid-organ transplant recipients have not been well defined. This study investigated the clinical features of COVID-19 infection in solid-organ transplant recipients at our center in Turkey. Materials and Methods: Our study included 23 solid-organ transplant recipients and 336 nontransplant individuals (143 previously healthy and 193 patients with at least 1 comorbidity) who were hospitalized due to COVID-19 disease in our hospital between March 2020 and January 2021. Demographic, clinical, and laboratory data of patients were compared. We used SPSS version 20.0 for statistical analysis. All groups were compared using chi-square and Mann-Whitney U tests. P <.05 was considered statistically significant. Results: Mean age of solid-organ transplant recipients was 49.8 +/- 13.7 years (78.3% men, 21.7% women). Among the 23 recipients, 17 (73.9%) were kidney and 6 (26.1%) were liver transplant recipients. Among nontransplant individuals, 88.7% (n = 298) had mild/moderate disease and 11.3% (n = 38) had severe disease. Among transplant recipients, 78.3% (n = 18) had mild/moderate disease and 21.7% (n = 5) had severe disease (P =.224). Transplant recipients had greater requirements for nasal oxygen (P =.005) and noninvasive mechanical ventilation (P =.003) and had longer length of intensive care unit stay (P =.030) than nontransplant individuals. No difference was found between the 2 groups in terms of mortality (P =.439). However, a subgroup analysis showed increased mortality in transplant recipients versus previously healthy patients with COVID-19 (P <.05). Secondary infections were major causes of mortality in transplant recipients. Conclusions: COVID-19 infection resulted in higher mortality in solid- organ transplant recipients versus that shown in healthy patients. More attention on secondary infections is needed in transplant recipients to reduce mortality.Item Clinical Characteristics and Outcomes of Nosocomial COVID-19 in Turkey: A Retrospective Multicenter Study(2023) Yildirim, Suleyman; Yilmaz, Celalettin; Polat, Gulru; Baris, Serap; Basyigit, Ilknur; Kaya, Ilknur; Anar, Ceyda; Bozkurt, Mihriban; Baykal, Husnu; Dirol, Hulya; Ozbey, Gamzenur; Ozsari, Emine; Cireli, Emel; Cirak, Ali; Tatar, Dursun; Gayaf, Mine; Karaoglanoglu, Selen; Aydin, Yener; Eroglu, Atilla; Olcar, Yildiz; Yildirim, Berna; Gursoy, Bengul; Yilmaz, Deniz; Niksarlioglu, Elif; Eren, Ramazan; Erdem, Aysegul; Tor, Muge Meltem; Fakili, Fusun; Colak, Mustafa; Ercelik, Merve; Tabaru, Ali; Ediboglu, OzlemObjective: To identify the clinical characteristics and outcomes of hospital-acquired SARS-CoV-2 infection during the vaccination period nationwide in Turkey. Methods: COVID-19 patients followed in the pandemic services across Turkey between January 1, 2021, and March 31, 2022 were investigated retrospectively. Nosocomial COVID-19 was defined as a patient neither diagnosed with COVID-19 nor suspected COVID-19 at the hospital admission and was confirmed COVID-19 >= 5 days after hospital admission. The primary outcome of this study was in-hospital mortality; demographic features and vaccination status was compared between survivors and non survivors. Results: During the study period, 15 573 COVID-19 patients were followed in 18 centers and 543 (3.5%) patients were nosocomial COVID-19. Most patients with nosocomial COVID-19 (80.4%) were transferred from medical wards. 162 (29.8%) of the patients with nosocomial COVID-19 admitted to the intensive care unit due to disease severity and 138 (25.4%) of the patients died during hospital stay. Advanced age (>= 65 years) and number of comorbid diseases (>= 2) was found to be associated with mortality in nosocomial COVID-19 (OR 1.74, 95% CI 1.11-2.74 and OR 1.60, 95% CI 1.02-2.56, respectively). Vaccination was associated with survival in nosocomial COVID-19 (OR 0.25, 95% CI0.16-0.38). Conclusions: Patients with nosocomial COVID-19 had increased admission to intensive care units and higher mortality rate. Vaccination can decrease the in-hospital mortality rate.
