We evaluated the association between serum uric acid (SUA) and atrial fibrillation (AF) in patients with chronic heart failure (HF). Totally, 363 patients with chronic HF were included in the study. Of all, 78 patients had AF and 285 patients were in normal sinus rhythm. Serum uric acid was significantly increased in patients with AF compared with patients in normal sinus rhythm (P < .05). Comparing patients with AF and normal sinus rhythm, we found that age was significantly higher in patients group with AF. Echocardiographic parameters including ejection fraction, left atrial diameter, left ventricle end-diastolic diameter, and left ventricle end-diastolic volume were also significantly higher in patients with AF compared with patients in normal sinus rhythm. We have shown that patients with AF have significantly higher SUA and this was independently associated with AF in patients with ischemic HF.

The procoagulant and prothrombotic states in patients with chronic atrial fibrillation are higher than those in patients with normal sinus rhythm. Mean platelet volume (MPV) which is a marker of platelet function and activation can reflect changes either in the level of platelet stimulation or the rate of platelet production. In this study, we aimed to assess and compare the hematologic parameters of routine complete blood count analysis in elderly patients with nonvalvular atrial fibrillation and control individuals with normal sinus rhythm. One hundred and seven consecutive patients with nonvalvular chronic atrial fibrillation and 112 age and sex-matched control individuals with normal sinus rhythm were retrospectively included in the study from the outpatient cardiology clinic. Hematological variables, including MPV, platelet count, red blood cell and white blood cell count were measured in all patients and control individuals. Presence of coronary artery disease, hypertension, sex, hyperlipidemia, diabetes mellitus, smoking status, hematocrit and platelet count were comparable between two groups (P>0.05 for all). However, MPV and white blood cell count were significantly higher in patients with atrial fibrillation compared to those without atrial fibrillation. Logistic regression analysis revealed that white blood cell count and MPV significantly and independently associated with atrial fibrillation. We have shown that MPV and white blood cell count is independently associated with chronic nonvalvular atrial fibrillation. To improve the clinical utility of MPV and role of inflammation in the pathogenesis of atrial fibrillation, further studies are needed to be carried out.

Procoagulant and prothrombotic states in patients with chronic atrial fibrillation (AF) are higher than those in patients with normal sinus rhythm. We assessed and compared serum g-glutamyltranferase (GGT) activity in elderly patients with nonvalvular AF and control participants with normal sinus rhythm. Consecutive patients (n ¼ 81) with nonvalvular chronic AF and 210 ageand gender-matched control participants with normal sinus rhythm were retrospectively included in the study from the outpatient cardiology clinic. Presence of coronary artery disease, hypertension, gender, hyperlipidemia, diabetes mellitus, smoking status, glucose, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and ejection fraction were comparable between the 2 groups (P > .05 for all). However, serum g-GGT activity was significantly higher (P ¼ .003) in patients with AF compared with those without AF. We have shown that serum g-GGT activity is independently associated with chronic nonvalvular AF.

BackgroundThere are very limited data on the prognostic capacity of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) for the systemic inflammatory response in pediatric trauma (PT) patients. The purpose of this study was to evaluate the prognostic ability of NLR and PLR on mortality in pediatric trauma patients.MethodsThis study looked at 358 PT patients who were admitted to the Cumhuriyet University Hospital’s Emergency Department between January 2010 and June 2018. The NLR and PLR were calculated by dividing the blood neutrophil count and blood platelet count, respectively, by the lymphocyte count, at the time of admission. After performing a stepwise logistic regression analysis to determine the predictive factors on the mortality risk of post-traumatic systemic inflammatory response syndrome (SIRS), receiver operating characteristic (ROC) curve analysis was used to define the optimum cut-off values of the NLR and the PLR parameters for survival.ResultsThe NLR, and PLR values were significantly higher in survivors than in non-survivors (NLR, 6.2±5.7 versus 2.6±2.5, P<0.001; PLR, 145.3±85.0 versus 46.2±25.2, P<0.001 ). The NLR (odds ratio [OR], 3.21; P=0.048), PLR (OR, 0.90; P=0.032), blood glucose (OR, 1.02; P=0.024), and Injury Severity Score (ISS) (OR, 1.28; P=0.011) were independent predictors of the mortality risk in PT patients. The area under the curve in the ROC curve analysis was 0.764 with a cut-off of 2.77 (sensitivity 70%, specificity 77%) for the NLR; and 0.928 with a cut-off of 61.83 (sensitivity 90%, specificity 85%) for the PLR.ConclusionAcquiring the NLR and PLR at the time of admission could be a useful predictor for mortality in PT patients.

AIM: We aimed to analyse the patients diagnosed with cardiac arrest in the emergency ward in accordance to their chronic illnesses, cardiac rhythm at the beginning of the cardiac arrest, the duration of the cardiopulmonary resuscitation and the mortality rates. METHODS: The records of 70 patients diagnosed with in-hospital

Introduction: Carbon monoxide (CO) poisoning is a crucial cause of delayed neuropsychiatric syndrome (DNS). However, most biomarkers are not satisfactory for the prediction of DNS caused by CO poisoning. Thus, we evaluated the adequacy of the serum glucose/potassium (GLU/K) ratio, which may be an easy, quick, and readily available parameter that can be used in the emergency department for predicting DNS. Methods: We evaluated 281 patients who were admitted to our emergency department between January 2012 and December 2018. The patients were divided into two groups: DNS (+) and DNS (−). The GLU/K was compared for the groups. Results: Glucose, blood urea nitrogen, carboxyhemoglobin, and GLU/K ratios of patients in the DNS (+) group were statistically significantly higher than those patients in DNS (−) group (140 ± 34 vs. 110 ± 24, p < 0.001; 17.58 ± 6.14 vs. 14.27 ± 5.08, p = 0.003; 29 ± 5.1 vs. 18.9 ± 7.6, p < 0.001; and 38.35 ± 10.11 vs. 28.65 ± 6.53, p < 0.001, respectively). The area under the curve for GLU/K to predict DNS was measured as 0.791, and 35.9 as a cut-off value had 63.6% sensitivity and 89.6% specificity. Conclusions: DNS development in CO poisoning is a serious and feared complication. We suggest that the GLU/K ratio has a high potential as a rapid, easy preliminary marker for the exclusion of patients who will not subsequently develop DNS.

Background Due to the growing evidence of the importance of iron status in immune responses, the biomarkers of iron metabolism are of interest in novel Coronavirus Disease 2019 (COVID-19). The present prospective study was carried out to compare iron status indicated by levels of ferritin with the levels of two novel biomarkers related to iron homeostasis, hephaestin and hypoxia-inducible factors-1 (HIF-1α) in the serum of patients with COVID-19 in comparison with a control group. Methods and results Blood samples from 34 COVID-19 patients and from 43 healthy volunteers were collected and the levels of HEPH and HIF-1α were measured by ELISA and compared with levels of serum ferritin. COVID-19 patients had higher serum levels of ferritin than those levels in control group (P < 0.0001). Conversely levels of HIF-1α and HEPH in the COVID-19 group were significantly lower than those of control group (P < 0.0001 for both). An inverse correlation between hephaestin and ferritin as well as between HIF-1α and ferritin was found among all subjects (P < 0.0001), and among COVID-19 patients, but not to statistical significance. Conclusion Levels of hephaestin and HIF-1α were found to be inversely related levels of ferritin across all participants in the study, and to our knowledge this is the first report of hephaestin and HIF-1α as potential markers of iron status. Further studies are needed to corroborate the findings, utilizing a broader range of markers to monitor inflammatory as well as iron status.
