Item The Impact of Comorbidities on Mortality in Patients with Non-Traumatic Major Lower Extremity Amputation(2023) Yagiz, Betul Keskinkilic; Goktug, Ufuk Utku; Sapmaz, Ali; Dinc, Tolga; Budak, Ali Baran; Terzioglu, Serdar Gokay; 38060412Objective: Major lower limb amputation is generally associated with a high risk of early and late-term mortality. In this study, 30-day, one-year and three-year mortality of non-traumatic major lower extremity amputations and comorbidities affecting the mortality rate were investigated. Method: Patients who underwent a major lower limb amputation secondary to diabetes or peripheral artery disease between the years 2010-2015 were retrospectively evaluated. Additional to patient demographic data and comorbidities, amputation level, survival and mortality time were extracted. Mortality rates after 30 days, one year and three years were analysed. The associations of the survival to different parameters were evaluated with Kaplan-Meier analysis and log rank test, while the impact of the risk factors on mortality was evaluated with the Cox regression test. Results: A total of 193 patients were enrolled in the study. Approximately 60% of patients were aged >= 65 years, and 65.8% were male. Below-knee amputation was performed in 64.8% of patients and above-knee amputation in 35.2% of patients. The mean follow-up of patients was 29.48 months (range: 0-101 months). After non-traumatic major lower extremity amputation, 30-day, one-year and three-year mortality were 16.6%, 38.3% and 60.1%, respectively. On Cox regression analysis, age >= 65 years was the only variable that had significant impact on the 30-day mortality (hazard ratio (HR): 3.4; p=0.012), while age >= 65 years (HR: 2.5, p=0.000), diabetes (HR: 2, p=0.006) and renal failure (HR: 2, p=0.001) were found to have significant impacts on three-year mortality. Conclusion: The findings of this study showed that >50% of patients with non-traumatic major lower limb amputations died within three years. Advanced age, diabetes and renal failure were the risk factors that increased the mortality. The high mortality rates revealed the importance of employing all hard-to-heal wound treatment options before making an amputation decision. Further, prospective studies are needed to determine the effects of primary disease status and timing of amputation on mortality.Item Spontaneous Giant Splenic Hydatid Cyst Rupture Causing Fatal Anaphylactic Shock: A Case Report and Brief Literature Review(2014) Belli, Sedat; Akbulut, Sami; Erbay, Gurcan; Kocer, Nazim Emrah; https://orcid.org/0000-0002-1706-8680; https://orcid.org/0000-0002-5943-9283; 24918138; AAK-5370-2021; AAM-5436-2021Hydatid disease is a parasitic infection characterized by cyst formation in any organ, although the liver and lungs are most commonly involved. Hydatid disease of the spleen is uncommon, representing <8% of all human hydatid diseases. Splenic hydatid cysts usually coexist with liver hydatid cysts (secondary form), although the spleen is the primary location (primary form) in some cases. The clinical signs and symptoms of splenic hydatid cysts depend on their size, relationship with adjacent organs, and complications. One of the complications of splenic hydatid cysts is cyst rupture either after trauma or spontaneously as a result of increased intracystic pressure. These cysts may rupture into a hollow organ, through the diaphragm into the pleural cavity, or directly into the peritoneal cavity. A splenic hydatid cyst that ruptures into the peritoneal cavity may cause complications, including signs of peritoneal irritation, urticaria, anaphylaxis, and death, as in our case. Therefore, a hydatid cyst rupture requires both emergency surgery and careful postoperative care. In this study, we present a case of a giant splenic hydatid cyst that ruptured into the peritoneal cavity without any trauma. A review of cases reported in the English literature about splenic hydatid cyst perforation is also discussed.Item Prognostic Value of Procalcitonin in Infection-Related Mortality of Cancer Patients(2016) Sedef, Ali Murat; Kose, Fatih; Sumbul, Ahmet Taner; Dogan, Ozlem; Kursun, Ebru; Yurdakul, Zafer; Gultepe, Bilge Sumbul; Mertsoylu, Huseyin; Sezer, Ahmet; Ozyilkan, Ozgur; https://orcid.org/0000-0002-0156-5973; https://orcid.org/0000-0002-5573-906X; https://orcid.org/0000-0002-1932-9784; https://orcid.org/0000-0002-6445-1439; https://orcid.org/0000-0001-8825-4918; 27569098; G-4827-2016; D-4793-2014; GZH-1913-2022; AAG-5020-2020; M-9530-2014; AAD-2667-2020; AAD-2817-2021Purpose: Infectious diseases are a major cause of morbidity and mortality in cancer patients. Tumor-induced inflammatory responses may increase the value of classical inflammatory markers in blood, so these markers may not be as useful in cancer patients as in non-cancer patients. Serum procalcitonin (PCT) is a sensitive and specific biomarker for severe infection, and has been shown to be unaffected by tumor-induced inflammatory response. In this study we aimed to evaluate the possible role of PCT in mortality in cancer patients with infection. Methods: In total, 104 consecutive adult cancer patients who presented with fever (body temperature >= 38.3 degrees C or >= 38 degrees C on two consecutive measurements) during follow-up and needing hospitalization for infection were enrolled in this study. Results: The majority (72%) of the patients were male. The most common diagnosis and type of infection were lung cancer (40.4%) and pneumonia (56.7%), respectively. The overall mortality rate was 17%. Statistical analysis showed a significant relationship between PCT levels and mortality (p=0.001), but not between classical inflammatory markers and mortality (p>0.05). The mortality rate of patients with a PCT value > 2 ng/mL was 34.3%, compared with 9.6% in patients with a PCT below this value (p=0.005). Furthermore, PCT predicted in-ward cancer patient mortality with a sensitivity of 66% and a specificity of 76%. Conclusion: PCT is a unique serum biomarker significantly related to infection-related mortality and predicts mortality with a relatively high sensitivity and specificity.Item Increased Mortality Among Renal Transplant Patients With Invasive Pulmonary Aspergillus Infection(2018) Balcan, Baran; Ozcelik, Umit; Ugurlu, Aylin Ozsancakli; Aydin, Mehtap; Nalcaci, Serdar; Karakayali, Feza Yarbug; 0000-0003-1073-2494; 0000-0003-3598-3986; 0000-0003-4044-9366; 0000-0002-1874-947X; 30235978; A-4721-2018; AAG-8651-2021; AAA-2925-2020; HLX-0937-2023; AAB-3888-2021Introduction: Renal transplantation is the most effective and preferred definite treatment option in patients with end-stage renal disease. Due to long-term immunesuppressive treatment, renal transplant recipients become vulnerable to opportunistic infections, especially to fungal infections. Method: This was a single-center, retrospective observational study of 438 patients who underwent renal transplantation between 2010 and 2016. Results: Thirty-eight renal transplant recipients who had lower respiratory tract infection with median age of 41.5 years were evaluated for invasive pulmonary aspergillus (IPA). Of these, 52.6% were female and 84.2% had living donors. Eleven of 38 lower respiratory patients were found to have IPA infection, 5 with proven infection. Compared to patients who did not have fungal pulmonary infection, patients with invasive aspergillus were older and had high fever, galactomannan levels, and leukocyte counts. Mortality was also higher in those patients. Having fever at the baseline and IPA infection was significantly associated with mortality in univariate analysis and remained related in multivariate model after adjustment for age, gender, and fever. Conclusion: Invasive pulmonary aspergillus infection is highly associated with increased mortality rates in renal transplant patients. Fungal pulmonary infections in immune-suppressed patients should be diagnosed and treated immediately in order to avoid the life-threatening complications and may greatly improve prognosis.Item In-Hospital Bleeding and Mortality in Acute Coronary Syndrome Patients Treated with Tirofiban and Potent P2Y12 Inhibitors(2022) Akinci, Sinan; Coner, Ali; Akbay, Ertan; Adar, Adem; Muderrisoglu, Haldun; 35860883Objective: In this study, we aimed to determine whether potent agents affect in-hospital bleeding and mortality compared to clopidogrel in patients with the acute coronary syndrome in whom tirofiban and P2Y12 inhibitor are used together. Methods: Patients who were treated interventionally between 2015 and 2020 and were using tirofiban were retrospectively screened. Clinical, laboratory, and angiographic findings were obtained from the hospital database. Patients were analyzed by dividing them into clopidogrel and prasugrel/ticagrelor groups. Results: Acute coronary syndrome patients (n = 227) who were treated interventionally were included in this retrospective study. Clopidogrel was given to 93 (41%), ticagrelor to 112 (49.3%), and prasugrel to 22 of the patients (9.7%). Compared to the ticagrelor/prasugrel group, the clopidogrel group was older and more were women, and the history of hypertension and previous coronary artery disease was higher (P, respectively: <.001; .001; .008; .0045). The creatinine value was higher, the basal hemoglobin was lower, and the GRACE (Global Registry of Acute Coronary Events) and CRUSADE (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA Guidelines) scores were higher (P, respectively:.026; .002;.002; <.001). The in-hospital bleeding rate was significantly higher in the clopidogrel group (P <.001). Although the in-hospital mortality rate was higher, it was not statistically significant (P = .07). Regression analysis showed that GRACE score and gender were associated with in-hospital mortality (P <.001; P = .031, respectively), and only age was associated with in-hospital bleeding (P <.001). No relationship was found with P2Y12 inhibitor. Conclusion: In our study, we found that the combined use of potent P2Y12 inhibitor with tirofiban in acute coronary syndrome patients treated interventionally was not different from the use of clopidogrel in terms of in-hospital bleeding and mortality.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 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 Increased frequency of occurrence of bendopnea is associated with poor outcomes in heart failure outpatients(2020) Kaya, Hakki; Sahin, Anil; Gunes, Hakan; Bekar, Lutfu; Celik, Ahmet; Cavusoglu, Yuksel; Caldir, Vedat; Gungor, Hasan; Yilmaz, Mehmet Birhan; 32812491Background Relationship between the frequency of occurrence of bendopnea during the daily life of heart failure (HF) outpatients and clinical outcomes has never been evaluated before. Methods Turkish Research Team-Heart Failure (TREAT-HF) is a network between HF centres, which undertakes multicentric observational studies in HF. Herein, the data including stable 573 HF patients with reduced ejection fraction out of seven HF centres were presented. A questionnaire was filled by the patients, with the question 'Do you experience shortness of breath while tying your shoelace?', assessing the presence and frequency of bendopnea. Results To the question related to bendopnea, 48% of the patients answered 'yes, every time', 31% answered 'yes, sometimes', and 21% answered 'No'. Patients were followed for an average of 24 +/- 14 months, and the patients who answered 'yes, every time' and 'yes, sometimes' to the bendopnea question were found having increased risk for both HF-related hospitalisations (HR:3.2,p < .001- HR:2.8,p = .005) and composite outcome consisting of 'HF-related hospitalisations and all-cause death in the multi-variate analysis (HR:3.1,p < .001- HR:3.0,p < .001). Kaplan Meier analysis for HF-related hospitalisation, all-cause death, and the composite of these were provided for these three groups, yielding significant and graded divergence curves with the best prognosis in 'no' group, with the moderate prognosis in 'sometimes' group, and with the worst prognosis in the 'every time' group. Conclusion For the first time in the literature, our study shows that the increased frequency of bendopnea occurrence in daily life is associated with poor outcomes in HF outpatients.Item SAPS III or APACHE IV: Which score to choose for acute trauma patients in intensive care unit?(2019) Toker, Melike Korkmaz; Gulleroglu, Aykan; Karabay, Ayse Gul; Bıcer, Ilhan Guncey; Demiraran, Yavuz; 31135940BACKGROUND: The aim of the present study was to evaluate the effectiveness of the Simplified Acute Physiology Score (SAPS) III and the Acute Physiology and Chronic Health Evaluation (APACHE) IV in the prediction of in-hospital mortality in surviving multi-trauma patients. METHODS: This study was conducted in the 13-bed intensive care unit (ICU) of a tertiary hospital. A retrospective review of multi-trauma patients whose care was managed in the ICU was performed. Data collection included details of age, gender, ICU admission, and outcome. APACHE IV and SAPS III scores, as well as the predicted mortality rate (PMR), were calculated using web-based calculators. RESULTS: Of the 90 patients 20% (n= 18) were female and 80% (n= 72) were male. The overall mortality rate was 25.6%. The mean APACHE IV, Acute Physiology Score (APS) and SAPS III score was 69.27 +/- 34.51, 66.42 +/- 33.72, and 26.36 +/- 27.14, respectively. The mean PMR according to the APACHE IV and the SAPS III was 26.36 +/- 27.14 and 17.07 +/- 24.88, respectively. The area under the curve result of receiver operating characteristic curve analysis was 0.87 for the APACHE IV and 0.93 for the SAPS III. CONCLUSION: The performance of the SAPS III was more sensitive and discriminative than the APACHE IV scoring system for multi-trauma ICU patients.Item Neutrophil/lymphocyte ratio and Red blood cell distribution width are independent risk factors for 30-day mortality in Gastrointestinal system bleeding patients(2019) Altinbilek, Ertugrul; Ozturk, Derya; Kavalci, CemilBackground. In this study, we aimed to examine demographic and endoscopic features of patients with GI bleeding to determine the factors affecting 30-day mortality. Method. Patient's demographic features, laboratory outcomes, comorbidities, drug use, endoscopy outcomes, Glasgow-Blatchford scores, and mortality status were examined. The factors affecting 30-day mortality were investigated. Results. The mean age of the patients was 58.2 +/- 17.4 years, and 72.1% were male patients. 30-day mortality rate was found to be 14.4%. The mean age of patients who died was high (p<0.05). The incidence of mortality was high in the presence of comorbidity, malignancy, and cirrhosis (p<0.05). Systolic blood pressure was low in the patients who died (p<0.05). No significant correlation was found between mortality and gender, symptoms, predisposing factors, lesion type and Forrest score, diastolic blood pressure and heart rate (p>0.05). Urea, neutrophils, red blood cell distribution width / platelet ratio, neutrophil / lymphocyte ratio and RDW levels were high, and hemoglobin level was significantly low in patients with a mortal progression (p<0.05). No significant correlation was found between mortality, and platelet and lymphocyte levels (p>0.05). Glasgow-Blatchford score was significantly higher in patients who died (p<0.05). Conclusion. Many factors affect 30-day mortality in GI bleeding. It should be remembered that follow-up of patients with an advanced age who have comorbidity and impaired hemodynamics should be kept for long, and that these patients are at a high risk for mortality. According to our results, NLR and RDW are independent factors that determine the 30-day mortality in upper GI bleeding.
