Item Analysis of the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the environmental Kuznets curve method(2022) Torun, Serife; Yilmaz, Kadir; Ozkaya, Sevket; Yosunkaya, Sebnem; Akcay, Sule; 36326361Background/aim: It was aimed to analyze the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the Environmental Kuznets Curve (EKC) Method. Materials and methods: WHO ICD-10 mortality list data and the World Bank Country Data (WBCD) were used between 1997 and 2017 for 12 countries. Cubic regression analysis was used for EKC Analysis. Results: The difference between male and female deaths between 1996 and 1998 has increased sharply since 1999. Male deaths consistently occurred significantly more than female deaths. There was a significant and negative correlation between Nitrous oxide emissions (% change from 1990) and tuberculosis-related deaths, whereas there were significant and positive correlations between Nitrous oxide emissions in the energy sector (% of total) and tuberculosis-related deaths (p < 0.01). EKC analysis results showed that there is a U shaped between tuberculosis-related mortality and nitrous oxide emission levels in the world. Conclusion: Research results show that the relationship between nitrous oxide change and mortality is negative in the short term and positive in the long term. Therefore, although nitrous oxide gases cause respiratory diseases and mortality, it may be possible to transform a harmful environmental factor into a positive by developing devices or methods that will convert these gases into free radicals.Item The role of neutrophil-to-lymphocyte ratio in predicting disease progression and emergency surgery indication in benign intestinal obstructions(2022) Tasci, Halil Ibrahim; 36043932BACKGROUND: The physiological response of the immune system to various stress factors results in an increase in neutrophil count and a decrease in lymphocyte count. In the light of this information, some studies have suggested using the ratio of these two parameters as an infection marker. The aim of this study was to investigate the role of neutrophil-to-lymphocyte ratio (NLR) derived from complete blood count, a very cost-effective and rapidly measurable parameter, in predicting the urgency of the surgical indication and disease progression in intestinal obstructions secondary to benign causes. METHODS: The data of patients who were admitted with the diagnosis of intestinal obstruction secondary to benign causes and underwent surgical intervention between January 2010 and January 2021 in Baskent University, Faculty of Medicine, Department of General Surgery, Konya Practice and Research Hospital were retrospectively analyzed. The data of 109 patients who met the study criteria and were included in the study were statistically analyzed. The correlation of admission NLR with factors indicating the severity of the disease such as intraoperatively detected ischemia, perforation, resection requirement, post-operative morbidity and mortality, and length of hospital stay was examined. Moreover, the diagnostic value of the NLR was compared with that of other infection mark-ers (such as C-reactive protein [CRP] and leukocyte). RESULTS: It was observed that the high NLR during admission to the hospital due to benign intestinal obstruction causes signif-icantly increased the risk of ischemia, resection requirement, post-operative complications, and mortality during surgery (p<0.05). Furthermore, increased NLR was found to be associated with prolonged hospitalization. In correlation analysis, consistent with the literature, a positive correlation was found between NLR and hospitalization time (p=0.03), CRP value (p<0.001), ischemia (p<0.001), perforation (p=0.007), presence of post-operative complications (p=0.009), and mortality (p=0.002). CONCLUSION: Our results show that the NLR has a very important role in predicting the course of the disease and surgical in-dication in benign intestinal obstructions.Item Hepatitis A susceptibility parallels high COVID-19 mortality(2021) Sarialioglu, Faik; Belen, Fatma Burcu; Hayran, Kadir Mutlu; 0000-0002-8257-810X; 0000-0002-9278-6703; 32718125; AAL-7766-2021Background/aim: COVID-19 has become the biggest health problem of this century. It has been hypothesized that immunity against hepatitis A virus (HAV) may provide protection from COVID19. Materials and methods: As of 10 June 2020, the infection had spread to 213 countries, with 7.3 million people infected and 413,733 dead. This data was combined with the World Health Organization susceptibility classification on the worldwide prevalence of HAV, and the relationship between HAV susceptibility and COVID-19 mortality were analyzed. Results: When the data from 213 countries were analyzed, it was found that there was a significant increasing trend in COVID-19 mortality rates by HAV susceptibility (P <0.001). Using a cut-off of 200/million population, the mortality risk associated with living in a more susceptible country (medium/high) was 27.8 times higher (95% CI for OR: 3.6-213.2) Conclusion: The results of this study showed that, despite confounding factors in different countries, hepatitis A susceptibility of the population may have been correlated with COVID-19 mortality. This observation needs to be confirmed by further studies.Item The Relationship Between COVID-19 Severity and Bacillus Calmette-Guerin (BCG)/ Mycobacterium Tuberculosis Exposure History in Healthcare Workers: A Multi-Center Study(2021) Torun, Serife; Ozkaya, Sevket; Sen, Nazan; Kanat, Fikret; Karaman, Irem; Yosunkaya, Sebnem; Sengoren Dikis, Ozlem; Asan, Ali; Aydogan Eroglu, Selma; Semih Atal, Sefa; Ayten, Omer; Aksel, Nimet; Ermis, Hilal; Ozcelik, Neslihan; Demirelli, Meryem; Kara, Iskender; Sumer, Sua; Marakoglu, Kamile; Uzer, Fatih; Uyar, Yasin; Cicek, Tuba; Unsal, Zuhal E.; Vatansev, Husamettin; Botan Yildirim, Berna; Kuruoglu, Tuba; Atilla, Aynur; Ersoy, Yasemin; Kandemir, Bahar; Durduran, Yasemin; Goksin Cihan, Fatma; Demirbas, Nur; Yildirim, Fatma; Tatar, Dursun; Akcay, M. Sule; 0000-0002-6530-6153; 0000-0002-8697-4919; 34014806; ABF-1652-2021The COVID-19 pandemic has brought countries' health services into sharp focus. It was drawn to our group's attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.Item Predictive Factors of Mortality in Granulomatosis with Polyangiitis: A Single-Center Study(2021) Tufan, Muge Aydin; Tekkarismaz, Nihan; 0000-0002-2686-9762; 0000-0001-7631-7395; 34870176; AAJ-9057-2021; AAD-9088-2021Objectives: The aim of this study was to identify predictors of mortality in granulomatosis with polyangiitis (GPA) patients and to seek the ways of improving survival in GPA patients. Patients and methods: Between January 2005 and June 2020, a total of 60 patients (26 males, 34 females; median age: 49 years; range, 19 to 75 years) who were diagnosed with GPA were retrospectively analyzed. Demographic, clinical, laboratory, and radiological findings of all patients were recorded. Survival rates were analyzed using the Kaplan-Meier plot. Results: The median follow-up was 36 months, and 10 (16.7%) patients died during the study period. Univariate analysis showed that the prognostic values were attributed to high serum creatinine levels (>2.1 mg/dL; p=0.01), proteinuria (p=0.01), dialysis-requiring renal damage at the time of diagnosis (p=0.01) or at any time during follow-up (p=0.01), low lymphocyte levels (p=0.01), hypoalbuminemia (p=0.04), absence of upper respiratory tract involvement (p=0.01), presence of lung involvement with cavitary lesions (p=0.01), high Birmingham Vascular Activity Score (p=0.02), and history of serious infection (p=0.01). In the multivariate analysis, the presence of renal damage requiring dialysis at any time during follow-up (relative risk [95% confidence interval]: 21 [4.1-18.3]; p=0.01) was found to be an independent predictor of mortality. Immunosuppressive drugs exerted no effect on mortality, and the most common causes of death were infections (50%). Conclusion: The presence of dialysis-requiring renal damage is the most important risk factor for mortality in GPA patients. These patients should be followed more closely and carefully to improve survival.Item An epidemiological study to define the recent clinical characteristics and outcomes of infective endocarditis in southern Turkey(2021) Acibuca, Aynur; Yilmaz, Mustafa; Okar, Sefa; Kursun, Ebru; Acilar, Onur; Tekin, Abdullah; Demiroglu, Yusuf Ziya; Muderrisoglu, Ibrahim Haldun; 0000-0002-9866-2197; 0000-0002-5658-870X; 33830167; AAZ-9711-2021; ABD-7304-2021Introduction: The aim of this study was to characterise the recent features of patients with infective endocarditis (IE) at one referral centre in southern Turkey, in order to be able to identify the high-risk subgroup and revise preventative measures and management strategies. Methods: Medical records of patients 18 years and older, who had been diagnosed with IE according to the Duke criteria between January 2009 and October 2019, were retrospectively evaluated in a referral general hospital. Results: The total of 139 IE cases comprised 59.7% males and 40.3% females, with a mean age of 55 +/- 16 years. The most encountered symptom was fever (55.4%) and the mitral valve (54%) was the most frequently involved. The most common causative micro-organisms were coagulase-negative staphylococci (30.2%). The in-hospital mortality rate was 30.2%, with congestive heart failure, chronic renal disease and chronic dialysis found to be significantly associated with in-hospital mortality. Conclusion: The study results demonstrate the recent epidemiological features of IE in southern Turkey that are important for clinicians to manage diagnostic and therapeutic processes successfully. Older age, the predominance of staphylococci and higher surgery rates are consistent with the changing trends of IE in some parts the world.Item Effects of personality traits on severity of sepsis(2021) Pehlivanlar Kucuk, Mehtap; Kucuk, Ahmet Oguzhan; Komurcu, Ozgur; Dikmen, Yalim; Kadioglu, Mustafa; Uzan, Cagdas Alp; Ergin Ozcan, Perihan; Orhun, Gunseli; Unal Akdemir, Neslihan; Eroglu, Ahmet; Ilyas, Yasir; Zeyneloglu, Pinar; Sahinturk, Helin; Dai Ozcengiz, Dilek; Firat, Ahmet; Aydin, Davut; Ozlu, Tevfik; Pehlivanlar, Aysegul; Kirakli, Cenk; Acar Cinleti, Burcu; Gok, Funda; Yosunkaya, Alper; Aktas, Murat; Ozturk, Cagatay Erman; Ulger, Fatma; 0000-0003-0159-4771; 34581156; AAJ-1419-2021Introduction: The aim of this study was to reveal the effect of the individual's lifestyle and personality traits on the disease process in patients with sepsis and to have clinical predictions about these patients. Materials and Methods: The study was planned as a multi-center, prospective, observational study after obtaining the approval of the local ethics committee. Patients were hospitalized in different intensive care units. Besides demographics and personal characteristics of patients, laboratory data, length of hospital and ICU stay, and mortality was recorded. Two hundred and fifty-nine patients were followed up in 11 different intensive care units. Mortality rates, morbidities, blood analyses, and personality traits were evaluated as primary outcomes. Results: Of the 259 patients followed up, mortality rates were significantly higher in men than in women (p=0.008). No significant difference was found between the patients' daily activity, tea and coffee consumption, reading habits, smoking habits, blood groups, atopy histories and mortality rates. Examining the personal traits, it was seen that 90 people had A-type personality structure and 51 (56.7%) of them died with higher mortality rate compared to type B (p=0.038). There was no difference between personalities, in concomitant ARDS occurrence, need for sedation and renal replacement therapies. Conclusion: Among individuals diagnosed with sepsis/septic shock, mortality increased significantly in patients with A-type personality trait compared to other personality traits. These results showed that personal traits may be useful in predicting the severity of disease and mortality in patients with sepsis/septic shock.Item Acute-Phase Stroke Outcome and Lipids(2021) Kaya, Ahmet; 35317377Objectives: The aim of the study is to investigate the relationship of lipid subgroups with short-term mortality in acute stroke (AS). Methods: This retrospective study included 698 patients with AS who presented within 24 h of symptom onset. A hemogram from peripheral venous blood samples was taken at admission. Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low- density lipoprotein cholesterol (LDL- C), TC/HDL-C rate, and TG/HDL-C rate were recorded. Duration of follow-up was defined as 30 days. Results: 64 out of 698 patients died during the follow-up period. The mean TG, TG/HDL-C, and TC/HDL-C levels were significantly lower in the mortality group than the survival group. In the receiver operating characteristic (ROC) analysis, the cutoff values and area under the curve of the TG, TG/HDL-C, TC, and TC/HDL- C levels for short-term stroke mortality are as follows ([100.2 mg/dL, 0.648]; [2.52, 0.650]; [170.50 mg/dL, 0.598]; and [4.32, 0.640], respectively). In the Cox regression model, only TG and TG/HDL-C, according to their ROC cutoff values, were independent variables as short-term mortality predictors ( TG =100.2 mg/dL, HR:2.413, 95% CI: 1.345-4.327, P:0.004); ( TG/HDL =2.56, HR: 2.720, 95% CI: 1.389-5.359, P:0.003, respectively). Conclusion: Dyslipidemia is a well-known as a risk factor of stroke. However, this study focused on the estimation that lower TG and TG/HDL-C levels at the time of hospital admission might be predictors of short-term mortality within a month of AS attack, which is a different subject from long term risk factors of stroke. Serum TG level may be a better indicator for mortality in the acute hypercatabolic trauma such as stroke.Item Long-term clinical outcomes of peritoneal dialysis patients: 9-year experience of a single centre in Turkey(2020) Tekkarismaz, Nihan; Torun, Dilek; 0000-0001-7631-7395; 0000-0002-6267-3695; 32041385; AAD-9088-2021; AAD-9111-2021Background/aim: The aim of this study was to evaluate the clinical outcomes and identity the predictors of mortality in peritoneal dialysis patients. Materials and methods: Medical records of all incident peritoneal dialysis (PD) patients followed up between January 2011 and May 2019 were reviewed retrospectively. All patients were followed up until death, renal transplantation, transfer to haemodialysis or the end of the study Results: A total of 242 patients were included in thestudy: The incidence of peritonitis was 0.18 (ranging from 0 to 14.9) episodes per patient year. Death occurred in 280 (n: 68) of cases. Age, diabetes mellitus, malignancy and refractory heart failure were independent risk factors for all-cause mortality according to multivariate analysis. 'the presence of comorbid disease and diabetes mellitus and patients aged > 65 years were associated with increased risk of mortality and decreased patient survival. Peritonitis history was associated with increased risk of mortality Between peritonitis and peritonitis-free group, there was no significant difference in Kaplan-Meier curves in terms of patient survival. Conclusion: This is the first study to define 9-year mortality predictors in PD patients in our centre. Although peritonitis is the most feared complication of PD, our study showed that peritonitis did ot reduce patient survival.Item Clinical characteristics and in-hospital outcomes of acute decompensated heart failure patients with and without atrial fibrillation(2020) Kocabas, Umut; Sinan, Umit Yasar; Arugaslan, Emre; Kursun, Mustafa; Coner, Ali; Celebi, Ozlem Ozcan; Ozturk, Cengiz; Dalgic, Onur; Turkoglu, Ebru Ipek; Kemal, Hatice Soner; Gazi, Emine; Altin, Cihan; Zoghi, Mehdi; 32352420Objective: Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases. The impact of AF on in-hospital outcomes in acute decompensated heart failure (ADHF) is controversial. The aim of this study is to determine the prevalence of AF among hospitalized patients with ADHF and describe the clinical characteristics and in-hospital outcomes of these patients with and without AF. Methods: We examined the multicenter, observational data from the real-life data of hospitalized patients with HF: Journey HF-TR study in Turkey that studied the clinical characteristics and in-hospital outcomes of hospitalized patients with ADHF between September 2015 and September 2016. Results: Of the 1,606 patients hospitalized with ADHF, 626 (39%) had a history of AF or developed new-onset AF during hospitalization. The patients with AF were older (71 +/- 12 vs. 65 +/- 13 years; p<0.001) and more likely to have a history of hypertension, valvular heart disease, and stroke. The AF patients were less likely to have coronary artery disease and diabetes. In-hospital adverse event rates and length of in-hospital stay were similar in ADHF patients, both with and without AF. In-hospital all-cause mortality rate was higher in patients with AF than in patients without AF, although the difference was not statistically significant (8.9% vs. 6.8%; p=0.121). Conclusion: AF has been found in more than one-third of the patients hospitalized with ADHF, and it has varied clinical features and comorbidities. The presence of AF is not associated with increased adverse events or all-cause mortality during the hospitalization time.
