    Abstract The signalling pathway of Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) is suggested to be involved in various pathophysiological processes, including immune function, cell growth, differentiation, hematopoiesis and more importantly oncogenesis of distinct tumoral conditions. Interleukin (IL) 6 is a proinflammatory cytokine produced by antigen-presenting cells and non-hematopoietic cells in response to external stimuli and considered to be a key player in the development of the microenvironment of malignancy by promoting tumor growth and metastasis by acting as a bridge between chronic inflammation and cancerous tissue. Recent studies suggest that aberrant interleukin IL6/JAK/STAT3 signaling pathway exists in both IBD and inflammation-related gastrointestinal cancers. In the present meta-analysis we aimed to analyze the relationship between IL-6/JAK/STAT3 and IBD associated colorectal carcinogenesis and the effect of the inhibition of this system on disease follow-up and management.In light of the small number of studies able to be included in the meta-analysis evidence strongly proposed that JAK/STAT3 signaling, especially via the IL-6/STAT3 axis is involved in the transition of inflammatory lesions to tumoral diseases and leading to ulcerative colitis associated colorectal cancer. For this reason, based on the evidence presented in this meta-analysis it is reasonable to suggest that targeting components of the IL-6/JAK/STAT3 signalling pathway can inhibit tumour cell growth and relieve immunosuppression in the UC associated colonic tumoral microenvironment.

    Abstract Introduction: Inflammatory bowel diseases (IBD) form a group of inflammatory diseases occurring in genetically-susceptible people, which are characterized by chronic progression and whose cause is not fully known. The aim of this study is to determine the incidence of IBD in our region and examine the clinical characteristics, sociodemographic features, and treatment results of IBD patients.Methods: Our study retrospectively investigates 211 patients over 18 years of age who were monitored for an IBD diagnosis between January 2, 2013, and December 31, 2019, by the gastroenterology department of Canakkale Onsekiz Mart University’s Faculty of Medicine. The mean age, female-male ratio, smoking habits, disease severity, and localization sites were identified for included patients. Local and systemic complications of administered treatment types and reasons for surgical treatment were also assessed in patients.Results: Of the 211 patients with IBD diagnoses, 158 (74.9%) had Ulcerative Colitis (UC) and 53 (25.1%) had a diagnosis of Crohn’s disease (CD). The mean age at the time of diagnosis was 43.97±16.22 years for UC patients and 42.30±14.73 years for CD cases. The involvement sites for UC were distal colitis for 58.4% of patients, left colon for 24.1% of patients, pancolitis for 16.5% of patients, and backwash ileitis for 7% of patients. According to the treatment results, 152 (72.0%) patients took 5-aminosalicylate (5-ASA) alone, 48 (22.8%) took thiopurine, and 20 (9.5%) took anti-TNF.Conclusion: Knowing the demographic, clinical, and laboratory features of these diseases, which are frequently seen in our region, can support the early identification of probable complications that may occur and the selection of appropriate approaches during diagnosis, treatment, and follow-up monitoring of these diseases.Keywords: Inflammatory Bowel Diseases, Ulcerative Colitis, Crohn’s Disease, Severity of Illness Index, Abdominal Pain, Diarrhea

    Abstract Background Mortality due to Covid-19 and severe community-acquired pneumonia (CAP) remains high, despite progress in critical care management. We compared the precision of CURB-65 score with monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) in prediction of mortality among patients with Covid-19 and CAP presenting to the emergency department. Methods We retrospectively analysed two cohorts of patients admitted to the emergency department of Canakkale University Hospital, namely (i) Covid-19 patients with severe acute respiratory symptoms presenting between 23 March 2020 and 31 October 2020, and (ii) all patients with CAP either from bacterial or viral infection within the 36 months preceding the Covid-19 pandemic. Mortality was defined as in-hospital death or death occurring within 30 days after discharge. Results The first study group consisted of 324 Covid-19 patients and the second group of 257 CAP patients. The non-survivor Covid-19 group had significantly higher MLR, NLR and PLR values. In univariate analysis, in Covid-19 patients, a 1-unit increase in NLR and PLR was associated with increased mortality, and in multivariate analysis for Covid-19 patients, age and NLR remained significant in the final step of the model. According to this model, we found that in the Covid-19 group an increase in 1-unit in NLR would result in an increase by 5% and 7% in the probability of mortality, respectively. According to pairwise analysis, NLR and PLR are as reliable as CURB-65 in predicting mortality in Covid-19. Conclusions Our study indicates that NLR and PLR may serve as reliable predictive factors as CURB-65 in Covid-19 pneumonia, which could easily be used to triage and manage severe patients in the emergency department.

    Abstract Background: The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte-ratio (PLR), and red blood cell distribution width (RDW) are simple indicators of inflammatory status previously established as a severity indicator in distinct disease states. This study aimed to determine the impact of these simple hematologic indices with conventional inflammation markers such as C-reactive pro-tein (CRP) and white blood cells in acute pancreatitis (AP) patients and their relationship with AP risk stratification scores including Bedside Index for Severity of Acute Pancreatitis (BISAP) and modified Glaskow Prognostic score (mGPS) scores.
    Methods: This retrospective study was performed in the emergency department of Canakkale Onsekiz Mart University. A total of 171 patients (male/female: 68 [39.8%]/103 [60.3%]) with AP and 59 age and gender matched healthy subjects (male/female: 23 [39%]/36[61%]) as controls were enrolled in the present study. The patients were grouped according to severity and adverse outcomes according to BISAP and mGPS and a comparative analysis was performed to compare the NLR, PLR, and RDW between groups.
    Results: The mean NLR values of AP patients and control group were 9.62±6.34 and 2.04±1.08, respectively (p<0.001), while the mean PLR values of AP patients and control group were 221.83±122.43 and 83.30±38.89, respectively (p<0.001). Except from RDW, all the other hematologic indices were found to be elevated (p<0.05 for WBC; NLR, PLR, and CRP) on both mild and severe disease at disease onset. NLR and PLR showed significant predictive ability for estimating serious complications associated with AP.
    Conclusion: The present study showed that NLR and PLR is increased in AP. Moreover, peripheral blood NLR and PLR values can predict disease severity and adverse outcomes associated with AP and can be used as an adjunctive marker for estimating disease severity.

    Abstract Purpose: In most countries, there is an ever-increasing admission rate of the elderly population into emergency departments (EDs). In particular, these elderly patients differ from younger patients because they have multiple comorbidities that affect the functionality and quality of life. The goal of this study is to reveal whether the Charlson comorbidity index (CCI) foresee the short- and long-term prognosis of the super-elderly patient population. Materials and Methods: The study was a descriptive, retrospective analysis of emergency department (ED) admissions by patients over 85 years of age and admitted to the Canakkale Onsekiz Mart University (COMU) Hospital between 2013 and 2018. The demographic data of the patients were analyzed according to CCI. Cox-regression analyses were conducted to determine whether the variables affected mortality. Results: A total of 1142 patients aged 85 and older (507 men, 635 women) with a mean age of 86.96±2.49 were included in the study. According to the multivariable Cox regression analysis male gender, CCI ≥6 and ICU admission were significantly associated with increased mortality rates Conclusion: The CCI predicts short and long-term prognosis in acutely ill, hospitalized super-elderly patients. The CCI could be used to select super-elderly patients at admission as an indicator of improvement at hospital discharge.

    Abstract COVID-19 due to the SARS-CoV-2 infection is a multi-systemic immune syndrome affecting mainly the lungs, oropharyngeal region, and other vascular endothelial beds. There are tremendous ongoing efforts for the aim of developing drugs against the COVID-19 syndrome-associated inflammation. However, currently no specific medicine is present for the absolute pharmacological cure of COVID-19 mucositis. The re-purposing/re-positioning of already existing drugs is a very important strategy for the management of ongoing pandemy since the development of a new drug needs decades. Apart from altering angiotensin signaling pathways, novel drug candidates for re-purposing comprise medications shall target COVID-19 pathobiology, including pharmaceutical formulations that antagonize proteinase-activated receptors (PARs), mainly PAR-1. Activation of the PAR-1, mediators and hormones impact on the hemostasis, endothelial activation, alveolar epithelial cells and mucosal inflammatory responses which are the essentials of the COVID-19 pathophysiology. In this context, Ankaferd hemostat (Ankaferd Blood Stopper, ABS) which is an already approved hemostatic agent affecting via vital erythroid aggregation and fibrinogen gamma could be a potential topical remedy for the mucosal management of COVID-19. ABS is a clinically safe and effective topical hemostatic agent of plant origin capable of exerting pleiotropic effects on the endothelial cells, angiogenesis, cell proliferation and vascular dynamics. ABS had been approved as a topically applied hemostatic agent for the management of post-surgical/dental bleedings and healing of infected inflammatory mucosal wounds. The anti-inflammatory and proteinase-activated receptor axis properties of ABS with a considerable amount of oestrogenic hormone presence highlight this unique topical hemostatic drug regarding the clinical re-positioning for COVID-19-associated mucositis. Topical ABS as a biological response modifier may lessen SARS-CoV-2 associated microthrombosis, endothelial dysfunction, oropharyngeal inflammation and mucosal lung damage. Moreover, PAR-1 inhibition ability of ABS might be helpful for reducing the initial virus propagation and mocasal spread of COVID-19.
