Background/Aim. Acute appendicitis (AA) is the most frequent emergency and appendectomy is the most frequent abdominal operation in the pediatric surgery. Diagnosis of AA in children is more difficult due to a lack of cooperation and poor clinical history data, leading to significant number of misdiagnostic cases. Our aim was to explore whether neutrophil to lymphocyte ratio (NLR) may be useful in diagnosis and follow-up of AA in children. Methods. Prospective investigation of NLR values in 129 consecutive patients admitted to the Mother and Child Healthcare Institute of Serbia and referred for surgery due to AA was performed. According to the pathohistological findings, patients were divided into 3 groups: normal/early, uncomplicated (phlegmonous) and complicated (gangrenous or/and perforated) AA. Laboratory analysis was done preoperativly and on the 1st and the 3rd postoperative days. Results. Statistically significant differences of NLR values were found in the different time points in total of patients and per groups. Some statistically significant differences of NLR values among histopathological groups were recorded. Investigations of correlation of NLR and other laboratory and clinical parameters showed strong positive correlation between NLR and C-reactive protein postoperatively and between NLR and Pediatric Appendicitis Score (PAS) preoperatively. Strong negative correlation with preoperative symptoms duration (PSD) were also present. Optimal cutoff NLR value between negative and positive appendectomies was 6.14. Conclusion. NLR provides well monitoring of progression of AA in children and, its cutoff values may help in distinguishing the phases of AA. Because of that, NLR should be used in diagnosis of AA in children.

Abstract Aim Neutrophil-to-lymphocyte ratio (NLR) predicts both diagnosis and severity of appendicitis. We aimed to evaluate accuracy of NLR to predict acute appendicitis and whether it can distinguish between uncomplicated and complicated appendicitis. Method Patients of any age and gender presenting with clinical history of acute appendicitis over a 4 month period were included. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of NLR were evaluated considering the cut-off values of 4.7 for acute appendicitis and 8.8 for complicated appendicitis. Results A total of 54 patients were included. Thirty-eight patients had acute appendicitis of whom 21 (55.2%) had complicated appendicitis. NLR was associated with sensitivity of 89.4%, specificity of 81.2%, PPV 91.8%, NPV of 76.5%, and accuracy of 87.0% for acute appendicitis. Moreover, it was associated with sensitivity of 61.4%, specificity of 78.9%, PPV 76.5%, NPV of 65.2%, and accuracy of 70.0% for complicated appendicitis. Conclusions NLR has acceptable sensitivity, specificity, PPV, NPV and accuracy to predict uncomplicated and complicated appendicitis with relatively better ability to predict the former. NLR can be utilised for prioritising cases for surgery, for monitoring conservatively treated patients and for patients who do not routinely undergo CT scan (pregnant or paediatric patients).

Abstract Objectives A tension headache is the most common type of headache, and its causes are multifactorial. A relationship has been shown between migraine headaches and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP). In this study, we investigated the NLR, PLR, and serum CRP levels in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH) patients. Materials and Methods This retrospective study included 64 patients with FETTH, 80 patients with CTTH, and 60 healthy controls who were followed up in the neurology clinic. Hematological parameters were compared between the patient and control groups. Results In CTTH patients, platelets, NLR, PLR, and CRP values were statistically higher than in FETTH patients and patients in the control group. In FETTH patients, the PLR value was higher than in patients in the control group, but there was no statistically significant difference in NLR and CRP values between FETTH patients and patients in the control group. Also, there was no correlation between these values and age and gender. Conclusion Increase platelet count might have an effect on tension-type headache pathophysiology. Systemic inflammation parameters were shown to be significantly higher in CTTH patients. More comprehensive studies are needed to evaluate the effect of systemic inflammation on the chronicity of tension headaches.

Aims: The present study aimed to investigate the prognostic role of derived neutrophil-to-lymphocyte ratio (dNLR) in patients with coronary heart disease (CHD) after PCI.Methods: A total of 3,561 post-PCI patients with CHD were retrospectively enrolled in the CORFCHD-ZZ study from January 2013 to December 2017. The patients (3,462) were divided into three groups according to dNLR tertiles: the first tertile (dNLR < 1.36; n = 1,139), second tertile (1.36 ≥ dNLR < 1.96; n = 1,166), and third tertile(dNLR ≥ 1.96; n = 1,157). The mean follow-up time was 37.59 ± 22.24 months. The primary endpoint was defined as mortality (including all-cause death and cardiac death), and the secondary endpoint was major adverse cardiovascular events (MACEs) and major adverse cardiovascular and cerebrovascular events (MACCEs).Results: There were 2,644 patients with acute coronary syndrome (ACS) and 838 patients with chronic coronary syndrome (CCS) in the present study. In the total population, the all-cause mortality (ACM) and cardiac mortality (CM) incidence was significantly higher in the third tertile than in the first tertile [hazard risk (HR) = 1.8 (95% CI: 1.2–2.8), p = 0.006 and HR = 2.1 (95% CI: 1.23–3.8), p = 0.009, respectively]. Multivariate Cox regression analyses suggested that compared with the patients in the first tertile than those in the third tertile, the risk of ACM was increased 1.763 times (HR = 1.763, 95% CI: 1.133–2.743, p = 0.012), and the risk of CM was increased 1.763 times (HR = 1.961, 95% CI: 1.083–3.550, p = 0.026) in the higher dNLR group during the long-term follow-up. In both ACS patients and CCS patients, there were significant differences among the three groups in the incidence of ACM in univariate analysis. We also found that the incidence of CM was significantly different among the three groups in CCS patients in both univariate analysis (HR = 3.541, 95% CI: 1.154–10.863, p = 0.027) and multivariate analysis (HR = 3.136, 95% CI: 1.015–9.690, p = 0.047).Conclusion: The present study suggested that dNLR is an independent and novel predictor of mortality in CHD patients who underwent PCI.

Introduction: Acute appendicitis in children is the most common acute surgical condition in children. Each year, 80000 children in the United States suffer from appendicitis. Objectives: The aim of this study was to evaluate diagnostic value of neutrophil to lymphocyte ratio (NLR) in younger and older pediatrics suspect of acute appendicitis in Imam Hossein hospital. Patients and Methods: This was a retrospective study conducted at Imam Hossein hospital from 2015-2017. The study population was all children with suspected appendicitis who refer to Imam Hossein medical center in Isfahan. The sample size was 423 people. The collected data were imported into SPSS software version 22 and analyzed with appropriate statistical tests. The significance level in the present study was less than 0.05. Results: The average age of participants was 7.2 ± 3.8 years. In both study groups, it was observed that the mean NLR in the normal and reactive follicular groups was significantly lower than the appendicitis and complication groups (P<0.05). The results of the present study showed that NLR diagnostic test can be a good predictor for the evaluation of appendicitis in both groups under 4 years and over 4 years. For more than 4 years’ group; AUC=0.74, P<0.001 and for less than 4 years’ group; AUC=0.69, P<0.001. For less than 4 years’ group, the cut-off score for appendicitis diagnosis was 2.3. In this cut-off, the sensitivity and specificity were equal to 0.65% and 0.72%. Additionally, for more than 4 years’ group, the cut-off for the diagnosis of appendix was 3.5. In this cut-off, the sensitivity and specificity were equal to 0.73% and 67%. Conclusion: This analysis demonstrates that NLR, in the context of appropriate clinical assessment of patients with a high a priori probability of appendicitis, has a greater diagnostic accuracy in supporting the diagnosis of appendicitis.

BackgroundInflammation is widely considered an important hallmark of cancer and associated with poor postoperative survival. The objective of this study is to assess the significance of preoperative C-NLR, a new inflammation-based index that includes preoperative C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), on therapeutic outcomes for bladder cancer (BC) patients after radical cystectomy (RC).Materials and MethodsBC patients who underwent RC between 2010 and 2019 were retrospectively analyzed from our medical center. The predictive effect of CRP, NLR, and C-NLR on the survival of BC patients were analyzed by the receiver operating characteristic (ROC) curves. The relationship between C-NLR and postoperative survival was investigated by Cox regression. The corresponding nomograms were built based on the Cox regression results of overall survival (OS) and disease-free survival (DFS), which were further validated by ROC curves, decision curve analysis (DCA) curves, and calibration curves.ResultsOf the 199 eligible patients, 83 (41.70%) were classified as high C-NLR group and the remaining 116 (58.30%) were classified as low C-NLR group. ROC analysis showed that C-NLR had the largest area under curve (AUC) compared to CRP and NLR. Multivariate analysis revealed that T-stage and C-NLR [high C-NLR vs. low C-NLR, hazard ratio (HR) = 2.478, 95% confidence interval (CI), 1.538–3.993, p &lt; 0.001] were independent predictors of OS, whereas T-stage, M-stage, and C-NLR (high C-NLR vs. low C-NLR, HR = 2.817, 95% CI, 1.667–4.762, p &lt; 0.001) were independent predictors of DFS. ROC and DCA analysis demonstrated better accuracy and discrimination of 3- and 5-year OS and DFS with C-NLR-based nomogram compared to TNM stage. The calibration curve reconfirmed the accurate predicting performance of nomograms.ConclusionC-NLR is a reliable predictor of long-term prognosis of BC patients after RC and will contribute to the optimization of individual therapy for BC patients.
