SUMMARY OBJECTIVE: Acute appendicitis is the most common cause of acute abdomen. It is important to differentiate between complicated and uncomplicated appendicitis before surgery in the emergency department. Recently, immature granulocytes have become one of the biomarkers used as predictors of inflammation. The aim of this study was to determine whether immature granulocyte levels are a biomarker that can predict whether acute appendicitis is complicated or not in patients admitted to the emergency department. METHODS: Patients aged 18 years and older who presented to the emergency department between May 1, 2023, and April 30, 2024, and were diagnosed with appendicitis were included in the study. Patients with a histopathologic diagnosis of acute appendicitis were divided into two groups: acute simple appendicitis (n=149) and acute complicated appendicitis (n=103). Demographic characteristics, imaging results, and laboratory results were recorded. RESULTS: White blood cell, neutrophil count and percentage, lymphocyte count and percentage, immature granulocyte count and percentage, direct bilirubin, C-reactive protein, and procalcitonin values were found to be significantly higher in the complicated appendicitis group than in the uncomplicated group (p-values; 0.001, <0.001, <0.001, <0.001, 0.001, <0.001, <0.001, <0.001, <0.001, 0.016, <0.001, and 0.001, respectively). The immature granulocyte percentage was 92% specific for the diagnosis of complicated appendicitis at a cut-off value of 0.6. CONCLUSION: The immature granulocyte percentage may be useful as a predictive biomarker in the diagnosis of complicated acute appendicitis with a specificity of 92%. Additionally, the immature granulocyte percentage has a higher discrimination power than the immature granulocyte count, C-reactive protein, and procalcitonin.

ABSTRACT Introduction: The benefit of implantable cardioverter-defibrillator (ICD) in patients with non-ischemic dilated cardiomyopathy (DCM) is still an issue under discussion. Studies examining the relationship between ventricular scar tissue and ICD shock with cardiac magnetic resonance (CMR) are promising. CMR studies have shown that ventricular scar tissue size and Selvester score show a correlation. In the light of this information, this study aimed to investigate the potential relationship between Selvester score and ICD therapies. Methods: The study included 48 patients who had undergone ICD implantation with a diagnosis of DCM and who had undergone routine 6-month ICD control in outpatient clinic controls between December 2018 and October 2019. Selvester score and other data were compared between patients who received ICD therapy (n=10) and those who did not (n=38). Results: Selvester score (P<0.001) was higher in ICD therapy group. Positive correlation was found between ICD shock therapy and Selvester score (P=0.002, r=0.843). Selvester score was detected as an independent predictor for ICD therapy after multiple linear regression analysis (P=0.004). Receiver operating characteristic curve analysis showed that Selvester score (P<0.001) was a significant predictor of ICD therapy. Selvester score cutoff points of 5 for were calculated to estimate ICD therapy, with a sensitivity of 100% and specifity of 81%. Conclusion: In our study, it was found that a high Selvester score may be a predictor for ICD therapies in patients with DCM. As an inexpensive and non-invasive method, Selvester score can help in the decision-making in these patients.

SUMMARY OBJECTIVE: This study aimed to evaluate the association between left ventricular ejection fraction recovery and the total oxidant status, total antioxidant capacity, and high-sensitivity C-reactive protein levels. METHODS: A total of 264 ST-elevation myocardial infarction patients were classified into two groups according to baseline and 6-month follow-up left ventricular systolic function: reduced and recovery systolic function. Predictors of the recovery of left ventricular ejection fraction were determined by multivariate regression analyses. RESULTS: Multivariable analysis indicated that oxidative status index, baseline left ventricular ejection fraction and peak creatine-kinase myocardial bundle level, and high-sensitivity C-reactive protein were independently associated with the decreased of left ventricular ejection fraction at 6-month follow-up. CONCLUSION: Oxidative stress and inflammation parameters were detrimental to the recovery of left ventricular ejection fraction in patients with ST-elevation myocardial infarction.

SUMMARY OBJECTIVE: T-wave positivity in the lead aVR is a marker of ventricular repolarization abnormality and provides information on short- and long-term cardiovascular mortality in heart failure patients, those with anterior myocardial infarction, and patients who underwent hemodialysis for various reasons. The aim of this study was to investigate the relationship between T-wave positivity in the lead aVR on superficial electrocardiogram and mortality from COVID-19 pneumonia. METHODS: This study retrospectively included 130 patients who were diagnosed with COVID-19 and treated as an outpatient or in the thoracic diseases ward in a single center between January 2021 and June 2021. All patients included in the study had clinical and radiological features and signs of COVID-19 pneumonia. The COVID-19 diagnosis of all patients was confirmed by polymerase chain reaction detected from an oropharyngeal swab. RESULTS: A total of 130 patients were included in this study. Patients were divided into two groups: survived and deceased. There were 55 patients (mean age: 64.76–14.93 years, 58.18 male, 41.12% female) in the survived group and 75 patients (mean age: 65–15 years, 58.67 male, 41.33% female) in the deceased group. The univariate and multivariate regression analyses showed that positive transcatheter aortic valve replacement (OR 5.151; 95%CI 1.001–26.504; p=0.0012), lactate dehydrogenase (OR 1.006; 95%CI 1.001–1.010; p=0.012), and d-dimer (OR 1.436; 95%CI 1.115–1.848; p=0.005) were independent risk factors for mortality. CONCLUSION: A positive transcatheter aortic valve replacement is useful in risk stratification for mortality from COVID-19 pneumonia.

Abstract Objective Ischemia/reperfusion (I/R) may cause irreversible damage to tissues and organs. We evaluated the effects of dexketoprofen on a renal I/R model in rats. Methods The study included 30 male rats. Control group received 1 mL of saline. Dexketoprofen group received 1 mL (25 mg) of dexketoprofen intraperitoneally. After 60 minutes renal ischemia, 23 hours reperfusion was applied. In Sham group, laparotomy was performed with a medial line incision without any additional procedure. Changes in the plasma malondialdehyde (MDA), renal tissue MDA, plasma glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT), BUN, creatinine and albumin levels, and histopathological changes were evaluated. Results CAT values were significantly lower in Control as compared with the Sham group. Plasma levels of MDA in the Control group were significantly higher than in the Dexketoprofen group. BUN and creatinine values were significantly higher in the Dexketoprofen group. The severity of tissue injury in the Dexketoprofen group was significantly higher than in Control and Sham groups Conclusion Although dexketoprofen reduces the I/R-induced systemic inflammation, it increases renal tissue damage.

Abstract Introduction: In this trial, we initially aimed to investigate the major predictive factors for prolonged mechanical ventilation (PMV) following cardiac surgery with cardiopulmonary bypass (CPB) in our center and, secondarily, we tried to find out the effects of the independent factors on mortality. Methods: Between July 2017 and August 2018, 207 patients who underwent cardiac surgery with CPB were retrospectively investigated. The patients were randomly divided into two subgroups according to the duration of ventilator dependence (group 1 <24 hours, n=164, 79%; group 2 >24 hours, n=43, 21%). Results: 207 patients (mean age 59.47±10.56) who underwent cardiac surgery with CPB were enrolled in this study (n=145, 70% of male patients; n=62, 30% of female patients). Amid these patients, 43 (n=43, 20.77%) had prolonged intubation time. After multivariate logistic regression analysis among preoperative factors, female gender (OR=2.321, P=0.028), leukocytosis (OR=1.233, P=0.006), perioperative lactate level (OR=1.224, P=0.027), CPB time (OR=1.012, P=0.012) and postoperative revision for bleeding (OR=23.125, P=0.040) were significantly detected. The effect of predictive factors on mortality after cardiac surgery was determined and found that PMV did not affect hospital mortality (OR=1.979, P=0.420). Conclusion: In our report, we revealed, differently from previous studies, that intraoperative lactate levels which manifest organ perfusion and oxygenation were included and were significantly different in the early extubation group compared to the PMV group. Female gender, preoperative leukocytosis, intraoperative CPB time, lactate levels and postoperative revision for bleeding were the independent predictive factors for PMV. Moreover, PMV did not affect the early-term mortality during hospital stay.

SUMMARY OBJECTIVE: We aimed to demonstrate the clinical utility of CHA2DS2-VASc and anticoagulation and risk factors in atrial fibrillation risk scores in the assessment of one year mortality in patients with abdominal aortic aneurysm. METHODS: We designed a retrospective cohort study using data from Suleyman Demirel University Hospital for the diagnosis of abdominal aortic aneurysm. The study included 120 patients with abdominal aortic aneurysm who underwent aortic computed tomography. Patients were divided into two groups according to presence of abdominal aortic aneurysm and the development of mortality. Predictors of mortality were determined by multiple logistic regression analysis. RESULTS: Multivariate regression analysis showed that CHA2DS2-VASc score, advanced age, female gender and elevated white blood cell counts were independent predictors of abdominal aortic aneurysm development while CHA2DS2-VASc score and elevated glucose levels were independent predictors of one year mortality in patients with abdominal aortic aneurysm. The concordance statistics for anticoagulation and risk factors in atrial fibrillation risk Score and CHA2DS2-VASc risk score respectively were 0.96 and 0.97 and could significantly predict one year mortality in patients with abdominal aortic aneurysm (p<0.001, and p<0.001, respectively). CONCLUSIONS: CHA2DS2-VASc and anticoagulation and risk factors in atrial fibrillation risk scores are easily obtained in an emergency setting and can accurately predict one year mortality as a noninvasive follow-up in patients with abdominal aortic aneurysm. These simple scores could be used as a point of care decision aid to help the clinician in counseling patients presenting with abdominal aortic aneurysm and their families on treatment protocols.

Abstract Objective: The aim of this study was to evaluate the value of CHA2DS2-VASc and Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) risk scores for prediction of postoperative atrial fibrillation (AF) development in patients undergoing coronary artery bypass grafting (CABG) operation. Methods: The population of this observational study consisted of 370 patients undergoing CABG operation. CHA2DS2-VASc and ATRIA risk scores were calculated for all patients and their association with postoperative AF (AF episode lasting > 5 min) were evaluated. Predictors of postoperative AF were determined by multiple logistic regression analysis. Results: During follow-up, 110 patients (29.7%) developed postoperative AF. With multiple logistic regression analysis, risk factors for postoperative AF were determined: ATRIA risk score (odds ratio [OR] 1.23; 95% confidence interval [CI] 1.11-1.36; P<0.001), fasting glucose level (OR 1.006; 95% CI 1.004-1.009; P<0.001), and 24-hour drainage amount (OR 1.002; 95% CI; 1.001-1.004; P<0.001). Receiver operating characteristic curve analyses showed that CHA2DS2-VASc and ATRIA risk scores were significant predictors for new-onset AF (C-statistic 0.648; 95% CI 0.59-0.69; P<0.001; and C-statistic 0.664; 95% CI 0.61-0.71; P<0.001, respectively). Conclusion: CHA2DS2-VASc and ATRIA risk scores predict new AF in patients undergoing CABG.

RESULTADOS Durante o acompanhamento, 136 pacientes (32,8%) desenvolveram FA pós-operatória. Com análise de regressão logística múltipla, foram determinados os fatores de risco para FA pós-operatória: glicemia de jejum (OR: 1,01; IC 95%: 1,00-1,01, p<0,001), idade (OR: 1,12; IC 95%: 1,07-1,17, p<0,001), fração de ejeção do ventrículo esquerdo (OR: 0,90; IC 95%: 0,87-0,94, p<0,001), sexo masculino (OR: 3,32; IC 95%: 1,39-7,90, p=0,007), quantidade de drenagem de 24 horas (OR: 1,004; IC 95%: 1,002-1,005, p<0,001), CAR (OR: 1,82; IC 95%: 1,53-2,16, p<0,001). A análise da curva de características operacionais do receptor mostrou que o CAR (estatística C: 0,75; IC 95%: 0,71-0,79, p<0,001) foi um preditor significativo de FA. CONCLUSÃO O novo marcador inflamatório CAR é confiável para prever o desenvolvimento de FA após a operação de revascularização miocárdica.

SUMMARY OBJECTIVE This study aimed to investigate the predictive value of the newly defined C-Reactive Protein (CRP)/Albumin Ratio (CAR) in determining the development of atrial fibrillation (AF) in comparison with other inflammatory markers, such as Neutrophil/Lymphocyte (N/L) Ratio and Platelet/Lymphocyte (P/L) Ratio, in patients undergoing Coronary Artery Bypass Grafting (CABG) surgery. METHODS The population of this observational study consisted of 415 patients undergoing CABG. The study cohort was subdivided into two groups based on the development of AF. Complete blood counts, serum CRP, and serum albumin levels were evaluated before the CABG. The CAR, N/L, and P/L ratios of all the patients were calculated. Predictors of postoperative AF were determined by multiple logistic regression analysis (MLRA). RESULTS During follow-up, 136 patients (32.8%) developed postoperative AF. With MLRA, independent risk factors for postoperative AF were determined as follows: fasting glucose level (OR: 1.01; 95 % CI: 1.00-1.01, P <0.001), age (OR: 1.12; 95 % CI: 1.07-1.17, P <0.001), left ventricle ejection fraction (OR: 0.90; 95 % CI: 0.87-0.94, P <0.001), male gender (OR: 3.32; 95 % CI: 1.39-7.90, P = 0.007), 24-hour drainage amount (OR: 1.004; 95 % CI: 1.002-1.005, P <0.001), and CAR (OR: 1.82; 95 % CI: 1.53-2.16, P <0.001). Receiver Operating Characteristic curve analysis showed that CAR (C-statistic: 0.75; 95% CI: 0.71-0.79, p< 0.001) was a significant predictor of AF. CONCLUSION Novel inflammatory marker CAR can be used as a reliable marker to predict the development of AF following CABG.

RESUMO Em pacientes com fibrilação atrial, a anticoagulação padrão com antagonista da vitamina K mais terapia antiplaquetária dupla (DAPT) com inibidor de P2Y12 e aspirina é o padrão de tratamento após intervenção coronária percutânea (ICP). Enquanto essa terapia reduz o risco de trombose e derrame, aumenta o risco de sangramento. Não está claro se o efeito antiplaquetário da aspirina e do clopidogrel pode piorar a fibrilação atrial (FA). OBJETIVO Analisar a resistência à aspirina plaquetária (AR) e ao clopidogrel (CR) em pacientes coronarianos agudos (SCA) com base no ritmo sinusal (SR) e na FA. MÉTODOS Neste estudo prospectivo, foram incluídos 543 pacientes (idade média: 62±12 anos; intervalo: 26-89 anos) em uso de aspirina e clopidogrel após o diagnóstico de síndrome coronariana aguda. AR e CR foram analisados por um dispositivo Multiplate® MP-0120, utilizando o método de agregometria de sangue total. RESULTADOS Os pacientes com FA apresentaram valores significativamente maiores para idade, volume médio de plaquetas e proteína C reativa de alta sensibilidade (p<0,01 para cada parâmetro). Da mesma forma, a agregação induzida por ácido araquidônico (Aspi) foi maior nos pacientes com FA em comparação com os pacientes com SR (666±218 vs. 187±179, p<0,001). Entre os pacientes com SCA, significativamente mais pacientes do sexo feminino apresentaram FA (p<0,001). A incidência de hipertensão no grupo FA foi maior em comparação com o grupo SR (p<0,001). No entanto, os níveis de difosfato de adenosina não foram expressivamente significativos nos dois grupos. CONCLUSÃO Nossos achados indicam que o efeito inibitório plaquetário da aspirina foi pior em pacientes com FA, sugerindo que a eficácia da aspirina pode ser menor na profilaxia do tromboembolismo, com maior risco de sangramento.

SUMMARY In patients with atrial fibrillation, standard anticoagulation with a vitamin K antagonist plus dual antiplatelet therapy with a P2Y12 inhibitor and aspirin is the standard of care after percutaneous coronary intervention (PCI). While this therapy reduces the risk of thrombosis and stroke, it increases the risk of bleeding. It is unclear whether the antiplatelet effect of aspirin and clopidogrel may worsen atrial fibrillation (AF). OBJECTIVE Thus we aimed to analyze platelet aspirin resistance (AR) and clopidogrel resistance (CR) in acute coronary (ACS) patients based on sinus rhythm (SR) and AF. METHODS In this prospective trial, we included 543 patients (mean age: 62± 12 years; range: 26 - 89 years) who were on aspirin and clopidogrel therapy after the diagnosis of acute coronary syndrome. AR and CR were analyzed by a Multiplate® MP-0120 device by using the method of whole blood aggregometry. RESULTS AF patients had significantly higher age, mean platelet volume, and High-Sensitivity C-Reactive Protein (p< 0.01 for each parameter). Similarly, Arachidonic-acid induced (ASPI) aggregation was higher in AF patients compared to SR patients (666±218 vs. 187±179, p<0.001). Among the ACS patients, significantly more female patients had AF (p<0.001). The incidence of hypertension in the AF group was higher compared to the SR group (p<0.001). However, adenosine diphosphate levels were not at a significant level in the two groups. CONCLUSION Our findings indicate that the platelet inhibitory effect of Aspirin was worse for patients with AF, suggesting that the effectiveness of aspirin may be less in the prophylaxis of thromboembolism and more a bleeding risk.

Abstract Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG). Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and divided into three groups: Group 1, classical method (using sharp dissection); Group 2, electrocautery; and Group 3, ultrasonic cautery. Levels of prostacyclin and nitric oxide derivatives were examined biochemically; vascular cell adhesion molecule 1 (VCAM-1) and endothelial nitric oxide synthetase (eNOS) values were assessed using immunohistochemical staining. RA preparation time, RA length/harvesting time ratio, and drainage amounts at the site of RA removal were compared. Results: Differences in RA preparation time (Group 1: 25±6 min, Group 2: 18±3 min, Group 3: 16±3 min, P<0.001) and length/harvesting time ratio (Group 1: 0.76±0.19 cm/min, Group 2: 0.98±0.16 cm/min, Group 3: 1.13±0.09 cm/min, P<0.001) were statistically significant among the groups. Levels of prostacyclin and nitric oxide derivatives were not statistically significant different, VCAM-1 and eNOS expressions were observed to be similar among the groups, and endothelial damage was detected in only one patient per group. Conclusion: Use of ultrasonic cautery during RA preparation considerably reduces the preparation time and postoperative drainage amount. However, the superiority of one method over the others could not be demonstrated when the presence of endothelial damage with both biochemical and histopathological evaluations was considered.

RESUMO OBJETIVO: O escore Anticoagulação e Fatores de Risco na Fibrilação Atrial (Atria), usado na detecção do risco tromboembólico e hemorrágico de pacientes com fibrilação atrial (FA), recentemente demonstrou predizer resultados clínicos ruins em pacientes com infarto agudo do miocárdio (SCA), independentemente de ter FA. Nosso objetivo foi analisar a relação entre os diferentes escores de risco e o desenvolvimento de nefropatia induzida por contraste (NIC) em pacientes com SCA submetidos à intervenção coronária percutânea (ICP) urgente e comparar a capacidade preditiva do escore de risco Atria com o escore de risco Mehran. MÉTODOS: Foram analisados 429 pacientes com infarto agudo do miocárdio com elevação do segmento ST (IAM-ST) submetidos à ICP de urgência entre janeiro de 2016 e fevereiro de 2017. Os pacientes foram divididos em dois grupos: aqueles com e sem NIC, e ambos os grupos foram comparados de acordo com as características clínicas, laboratoriais e demográficas, incluindo os escores de risco CHA2DS2-VASc e Atria. Preditores de NIC foram determinados por análise de regressão multivariada. A análise da curva características de operação do receptor (ROC) foi utilizada para analisar o valor prognóstico dos escores de risco CHA2DS2-VASc e Atria para NIC, após IAM-ST. RESULTADOS: A análise de regressão multivariada mostrou que o escore de risco Atria, a relação opaca/crCl e a baixa fração de ejeção do ventrículo esquerdo foram preditores independentes de NIC. A estatística-C para o escore de risco Atria e o escore de risco CHA2DS2-VASC foi de 0,66 e 0,64 (p<0,001 e p<0,001), respectivamente. Uma comparação de pares de curvas características de operação do receptor mostrou que ambos os escores foram não inferiores ao escore Mehran na previsão de NIC. CONCLUSÃO: Os sistemas de pontuação Atria e CHA2DS2-VASC foram sistemas úteis para a detecção de NIC após IAM-ST.

SUMMARY BACKGROUND: The AnTicoagulation and Risk factors In Atrial fibrillation (ATRIA) risk score used to detect the thromboembolic and hemorrhagic risk in atrial fibrillation patients has been shown recently to predict poor clinical outcomes in patients with acute myocardial infarction (ACS), regardless of having atrial fibrillation (AF). We aimed to analyze the relationship between different risk scores and contrast-induced nephropathy (CIN) development in patients with ACS who underwent urgent percutaneous coronary intervention (PCI) and compare the predictive ability of the ATRIA risk score with the MEHRAN risk score. METHODS: We analyzed 429 patients having St-segment Elevation Myocardial Infarction (STEMI) who underwent urgent PCI between January 2016 and February 2017. Patients were divided into two groups: those with and those without CIN and both groups were compared according to clinical, laboratory, and demographic features, including the CHA2DS2-VASc and ATRIA risk score. Predictors of CIN were determined by multivariate regression analysis. Receiver operating characteristics (ROC) curve analysis was used to analyze the prognostic value of CHA2DS2-VASc and ATRIA risk score for CIN, following STEMI. RESULTS: Multivariate regression analysis showed that Athe TRIA risk score, Opaque/Creatinine Clearance ratio, and low left ventricular ejection fraction was an independent predictor of CIN. The C-statistics for the ATRIA risk score and CHA2DS2-VASC risk score were 0.66 and 0.64 (p<0.001, and p<0.001), respectively. A pair-wise comparison of ROC curves showed that both scores were not inferior to the MEHRAN score in predicting CIN. CONCLUSION: The ATRIA and CHA2DS2-VASC scoring systems were useful for detecting CIN following STEMI.
