    Background: Direct oral anticoagulants (DOACs) have been used in acute pulmonary thromboembolism as an alternative to warfarin due to drug interactions, narrow therapeutic range, and necessary close International Normalized Ratio (INR) monitoring. Phase 3 study results have reported that these drugs are at least as effective as warfarin and beneficial in terms of bleeding; however, studies that present up-to-date life data are necessary. Aims: To evaluate the frequency of using DOACs, which are prescribed with a limited number of indications in our country, and real-life data results. Study Design: Cross-sectional study Methods: This cross-sectional survey collected the clinical data (history, current treatment, treatment duration, etc.) of patients with pulmonary thromboembolism and who applied to the physician for follow-up between October 15, 2019, and March 15, 2020. The researchers kept the patient records sequentially. Results: Data from 836 patients with acute pulmonary thromboembolism from 25 centers were collected, and DOAC was used in 320 (38.5%) of them. The most preferred DOAC was rivaroxaban (n = 294, 91.9%). DOAC was mostly preferred because it could not provide an effective INR level with warfarin (n=133, 41.6%). Bleeding was observed in 13 (4%) patients. Conclusion: The use of direct oral anticoagulants is becoming almost as widespread as conventional therapy. Real-life data results are important for their contribution to clinical practice.

    Small Cell Lung Cancer Stem Cells Display Mesenchymal Properties And Exploit Immune Checkpoint Pathways In Activated Cytotoxic T Lymphocytes
    (2021) Kursunel, M. Alper; Taskiran, Ekim Z.; Tavukcuoglu, Ece; Yanik, Hamdullah; Demirag, Funda; Karaosmanoglu, Beren; Ozbay, Feyza Gul; Uner, Aysegul; Esendagli, Dorina; 0000-0002-6619-2952; 34228218; ABF-9398-2020
    Small cell lung cancer (SCLC) is an aggressive tumor type with early dissemination and distant metastasis capacity. Even though optimal chemotherapy responses are observed initially in many patients, therapy resistance is almost inevitable. Accordingly, SCLC has been regarded as an archetype for cancer stem cell (CSC) dynamics. To determine the immune-modulatory influence of CSC in SCLC, this study focused on the characterization of CD44(+)CD90(+) CSC-like subpopulations in SCLC. These cells displayed mesenchymal properties, differentiated into different lineages and further contributed to CD8(+) cytotoxic T lymphocytes (CTL) responses. The interaction between CD44(+)CD90(+) CSC-like cells and T cells led to the upregulation of checkpoint molecules PD-1, CTLA-4, TIM-3, and LAG3. In the patient-derived lymph nodes, CD44(+) SCLC metastases were also observed with T cells expressing PD-1, TIM-3, or LAG3. Proliferation and IFN-gamma expression capacity of TIM-3 and LAG3 co-expressing CTLs are adversely affected over long-time co-culture with CD44(+)CD90(+) CSC-like cells. Moreover, especially through IFN-gamma secreted by the T cells, the CSC-like SCLC cells highly expressed PD-L1 and PD-L2. Upon a second encounter with immune-experienced, IFN-gamma-stimulated CSC-like SCLC cells, both cytotoxic and proliferation capacities of T cells were hampered. In conclusion, our data provide evidence for the superior potential of the SCLC cells with stem-like and mesenchymal properties to gain immune regulatory capacities and cope with cytotoxic T cell responses. With their high metastatic and immune-modulatory assets, the CSC subpopulation in SCLC may serve as a preferential target for checkpoint blockade immunotherapy .

    New challenges for management of COVID-19 patients: Analysis of MDCT based "Automated pneumonia analysis program"
    (2021) Sezer, Rahime; Esendagli, Dorina; Erol, Cigdem; Hekimoglu, Koray; 34307790
    Purpose: The aim of this study is to define the role of an "Automated Multi Detector Computed Tomography (MDCT) Pneumonia Analysis Program" as an early outcome predictor for COVID-19 pneumonia in hospitalized patients. Materials and Methods: A total of 96 patients who had RT-PCR proven COVID-19 pneumonia diagnosed by non contrast enhanced chest MDCT and hospitalized were enrolled in this retrospective study. An automated CT pneumonia analysis program was used for each patient to see the extent of disease. Patients were divided into two clinical subgroups upon their clinical status as good and bad clinical course. Total opacity scores (TOS), intensive care unit (ICU) entry, and mortality rates were measured for each clinical subgroups and also laboratory values were used to compare each subgroup. Results: Left lower lobe was the mostly effected side with a percentage of 78.12 % and followed up by right lower lobe with 73.95 %. TOS, ICU entry, and mortality rates were higher in bad clinical course subgroup. TOS values were also higher in patients older than 60 years and in patients with comorbidities including, Hypertension (HT), Diabetes Mellitus (DM), Chronic Obstructive Pulmonary Disease (COPD), Chronic Heart Failure (CHF) and malignancy. Conclusion: Automated MDCT analysis programs for pneumonia are fast and an objective way to define the disease extent in COVID-19 pneumonia and it is highly correlated with the disease severity and clinical outcome thus providing physicians with valuable knowledge from the time of diagnosis.

    Unclear Issues Regarding COVID-19
    (2020) Esendagli, Dorina; 0000-0002-6619-2952; 32612430; ABF-9398-2020
    Scientists from all over the world have been intensively working to discover different aspects of Coronavirus disease 2019 (COVID-19) since the first cluster of cases was reported in China. Herein, we aimed to investigate unclear issues related to transmission and pathogenesis of disease as well as accuracy of diagnostic tests and treatment modalities. A literature search on PubMed, Ovid, and EMBASE databases was conducted, and articles pertinent to identified search terms were extracted. A snow-ball search strategy was followed in order to retrieve additional relevant articles. It was reported that viral spread may occur during the asymptomatic phase of infection, and viral load was suggested to be a useful marker to assess disease severity. In contrast to immune response against viral infections, cytotoxic T lymphocytes decline in SARS-CoV-2 infection, which can be partially explained by direct invasion of T lymphocytes or apoptosis activated by SARS-CoV-2. Dysregulation of the urokinase pathway, cleavage of the SARS-CoV-2 Spike protein by FXa and FIIa, and consumption coagulopathy were the proposed mechanisms of the coagulation dysfunction in COVID-19. False-negative rates of reverse transcriptase polymerase chain reaction varied between 3% and 41% across studies. The probability of the positive test was proposed to decrease with the number of days past from symptom onset. Safety issues related to infection spread limit the use of high flow nasal oxygen (HFNO) and continuous positive airway pressure (CPAP) in hypoxic patients. Further studies are required to elucidate the challenging issues, thus enhancing the management of COVID-19 patients.

    The whole world has been facing the pandemic of SARS-CoV-2 infection and every day we still find out new knowledge regarding the disease. COVID-19 which is the name given to the clinical syndrome related to this infection has been shown to own a wide diversity of clinical presentations which challenges the healthcare workers and makes difficult the diagnosis and management of patients. Pulmonary embolism is also an entity that accompanies this type of infection and sometimes it is difficult to differentiate between the two. Here we present a patient who was admitted inward with typical lesions on chest tomography for COVID-19, but that turned out to be a submassive pulmonary embolism case without any infection. This case is remarkable because it shows that patients suspected for COVID-19 should be carefully examined and that pulmonary embolism can per se mimick the parenchymal lesions caused by viral infections.

    COVID-19 Treatment at a Glance
    (2020) Esendagli, Dorina; 0000-0002-6619-2952; 33352100; ABF-9398-2020
    As coronavirus disease 2019 (COVID-19) spreads across the world, the ongoing clinical trials are leading to a big race worldwide to develop a treatment that will help control the pandemic. Unfortunately, COVID-19 does not have any known effective treatment with reliable study results yet. In this pandemic, there is not a lot of time to develop a new specific agent because of the rapid spread of the disease. The process of developing a vaccine is long and requires hard work. Although the pathophysiology of the disease is not fully understood, some of the proposed treatment alternatives are based on old evidence and some have been used with the idea that they might work owing to their mechanism of action. The efficacy, reliability, and safety of the currently available treatment alternatives are therefore a matter of debate. Currently, the main therapies used in the treatment of COVID-19 are antiviral drugs and chloroquine/hydroxychloroquine. Other proposed options include tocilizumab, convalescent plasma, and steroids, but the mainstay of the treatment in intensive care units remains supportive therapies.

    Covid-19: The Biggest Threat of the 21st Century: In Respectful Memory of the Warriors All Over the World
    (2020) Karcioglu, Oguz; Yuksel, Aycan; Baha, Ayse; Er, Aslihan Banu; Esendagli, Dorina; Gulhan, Pinar Yildiz; Karaoglanoglu, Selen; Ercelik, Merve; Serifoglu, Irem; Yildiz, Ethem; Kokturk, Nurdan; 0000-0002-6619-2952; 33352097; ABF-9398-2020
    Since the first case was diagnosed in China, the new coronavirus infection (COVID-19) has become the number one issue in the world and it seems to remain trend-topic for a long time. Until 17 April, it affected 210 countries, infected over 2 million people and caused approximately 150000 deaths. Although the course of the disease ranges from asymptomatic state to severe ARDS; the majority of patients reveal only mild symptoms. Though adults are the most commonly affected group; it can also be seen in newborns and elderly patients. Unfortunately, elderly patients are the most vulnerable group with higher mortality. Elderly patients, smokers and patients with comorbid conditions are most affected by the disease. In certain diagnostical tool is the real-time reverse transcription-polymerase chain reaction (real-time RT-PCR) test. However, it can be resulted in false-negative results and in this case the computed thorax tomography (CT) is one of the most important tools with high sensitivity. Besides the supportive treatment, most commonly used agents are immunomodulatory drugs such as plaquenil and azitromycin, and anti-virals including oseltamivir, ritonavir-lopinavir, favipiravir. Until a vaccine or a specific therapy invented, the most important intervention to control the disease is to fight against transmission. This is a real war and the doctors are the soldiers.

    Humidification therapy; long-term effects in COPD and OSAS patients
    (2018) Esendagli, Dorina; Sarric Ulasli, Sevinc; Esquinas, Antonio; 0000-0002-6619-2952; 30020043; ABF-9398-2020
    Humidification therapy is widely used in patients during invasive ventilation and the importance of heating and humidifying the inhaled air is well defined in both the acute and long term setting. On the other hand the continuous usage of humidification in noninvasive ventilation is controversial and the long term effects are still not well defined. The usage of noninvasive ventilation is especially important in hypercapnic Chronic obstructive pulmonary disease (COPD) and also the obstructive sleep apnea syndrome (OSAS) patients and compliance to this treatment is essential in long term. Limited number of studies have shown that heated humidification is preferred by COPD patients and might help in mucus clearance, reduce mucus viscosity and help in expectoration, but there was shown no priority as far as concerns the lung function or blood gas parameters. Humidification might also be important in long term oxygen treatment since the inhalation of dry air can lead to ciliary dysfunction, alterations in mucus properties and mucociliary clearance impairment. Studies concerning OSAS patients showed that humidification helps to reduce the nasal symptoms but plays no role in increasing the compliance of patients in long term. Multi-center studies with large number of patients are needed to identify patients' groups who are likely to benefit from the addition of humidification to noninvasive therapy.
