Objective To evaluate the role of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-neutrophil ratio (PNR), platelet-to-monocyte ratio (PMR), and neutrophil-to-monocyte ratio (NMR) as predictors for lupus nephritis (LN) patients without infection or as biomarkers for distinguishing between infection or flare with LN patients. Methods LN patients were divided into three groups: LN without infection, LN with infection, and LN with flare. A total of 57 healthy subjects were enrolled as controls. The differentiation was analyzed between LN without infection and control group, and LN with infection and LN with flare. Correlations among variables were assessed in the LN group without infection. Receiver operating characteristic curves were constructed in two comparable groups. Results NLR, PLR, and MLR were increased significantly in the LN group without infection as compared with those in healthy controls. NLR (area under the curve (AUC): 0.75) and MLR (AUC: 0.79) were useful for distinguishing between LN patients without infection and healthy subjects. In differentiating LN patients without infection from the controls, optimal cutoffs of NLR and MLR were 3.43 (sensitivity: 45.6%, specificity: 96.5%, and overall accuracy: 68.8%) and 0.24 (sensitivity: 75.0%, specificity: 73.7%, and overall accuracy: 73.6%), respectively. In addition, NLR ( r = 0.322, p = 0.011) and PLR ( r = 0.283, p = 0.026) were positively correlated with CRP. Importantly, NLR and NMR were increased while PNR was decreased in the LN group with infection in comparison with those in the LN group with flare. NLR (AUC: 0.80), NMR (AUC: 0.78), and PNR (AUC: 0.74) were useful in differentiating LN patients with infection and flare, and their optimal cutoffs were 4.02 (sensitivity: 82.6%, specificity: 69.6%, and overall accuracy: 75.5%), 12.19 (sensitivity: 80.4%, specificity: 73.9%, and overall accuracy: 77.5%), and 28.26 (sensitivity: 65.2%, specificity: 76.8%, and overall accuracy: 71.6%), respectively. Conclusions We demonstrated, for the first time, that MLR or NMR had the best accuracy in differentiating LN patients without infection from healthy subjects, or differentiating infection from flare in LN patients, respectively. Our results implied that NLR, MLR, PNR, and NMR may be useful biomarkers in predicting LN.

AbstractBy setting out from increased neutrophil count, decreased lymphocyte count, and increased mean platelet volume (MPV), which is a result of the effect of inflammation on blood cells, we aimed to investigate whether neutrophil to lymphocyte ratio (NLP) and MPV can be used as an auxiliary parameter for the diagnosis of early-onset neonatal sepsis (EOS). This study was conducted by analyzing term neonates with EOS and physiological jaundice who were admitted to the neonatal intensive care unit of Izmir Katip Celebi University Ataturk Training and Research Hospital. A total of 63 neonate files were examined to include 30 term neonates with EOS, and 77 neonate files were examined to include 30 term neonates with physiological jaundice as a control group. NLR had an area under the curve (AUC) of 0.891 for prediction of EOS. At a cut-off level of 1.42, NLR had a likelihood ratio (LR) of 5.5, sensitivity of 88%, a specificity of 84%, a positive predictive value (PPV) of 84.6%, and a negative predictive value (NPV) of 87.5%. MPV had an AUC of 0.666 for the prediction of EOS and at a cut-off level of 9.3 fL, MPV had an LR of 1.23, sensitivity of 84%, a specificity of 32%, a PPV of 55.2%, and an NPV of 66.6%. In conclusion, this study provides evidence that NLR and MPV can be used in addition to conventional parameters in the diagnosis of EOS.

Abstract The role of inflammation has been identified in the pathogenesis of diabetic ketoacidosis (DKA). The neutrophil/lymphocyte ratio (NLR) and white blood cells (WBC) can be used to predict a systemic inflammatory response. Changes in NLR and WBC levels have never been explored in type 1 diabetes mellitus (T1DM) patients with DKA and an uninfected state. This retrospective study included a total of 644 participants. NLR and WBC were measured in the control group (n = 316) and in T1DM patients with mild-DKA (n = 92), severe-DKA (n = 52), and non-DKA (n = 184) in an uninfected state. Then, we assessed the independent predictors of DKA occurrence in T1DM patients in an uninfected state. The diagnostic performance of variables was determined by receiver operating characteristic curve analysis. Serum NLR of T1DM patients is significantly higher than that of normal controls, and if DKA occurs, NLR increases further and increases with the severity of DKA. In addition to diastolic blood pressure, blood urea nitrogen, glycated hemoglobin (HbA1c), and WBC, NLR was also independently associated with DKA in T1DM patients with an uninfected state (OR = 1.386, 95% CI: 1.127–1.705, p = 0.002). Furthermore, the diagnosis analysis showed that except for NLR and WBC, the area under the curve (AUC) of indicators with a statistical difference in patients with and without DKA were 0.747 for DKA diagnosis, and after the addition of NLR and WBC, the AUC was 0.806. The increased NLR level represents a low-cost and highly accessible predictor for DKA in T1DM patients with an uninfected state. The addition of inflammation indicators can play a statistically significant role in the prediction model of the DKA occurrence.

Introduction: Blood neutrophil/lymphocyte ratio (NLR) is a simple marker of subclinical inflammation that can be easily obtained. The NLR has recently emerged as a prognostic marker in patients with cancer and coronary artery disease. However, little is known about the role of NLR in patients with intracranial aneurysm (IA). Hypothesis: The purpose of this study was to determine the clinical significance of NLR in patients with IA. Methods: The study group consisted of patients with IA who had been admitted to the neurology department from January 2008 to December 2014. A total of 362 patients including 176 patients with unruptured IA, 186 patient with ruptured IA were enrolled in this study. The control group consisted of 178 age, sex-matched healthy adults who had not harbor IA by CTA, MRA, DSA. The baseline NLR was calculated as the ratio of neutrophil count to lymphocyte count. WBC count>12.000 cells per μL or <4.000 cells per μL and high body temperature>38 ° are excluded from the study. Results: The Mean NLR was significantly higher among persons with cerebral aneurysm compared with controls (P < 0.001). The level of NLR in ruptured IA group were found higher compared to unruptured IA and control group (7.0 ± 6.6 vs 2.5 ± 1.5 vs 1.6 ± 0.5, P < 0.001). Other comorbid conditions were balanced between these three groups. Conclusions: Higher NLR is associated with cerebral aneurysm. Unlike many other inflammatory markers and bioassays, NLR are inexpensive and readily available biomarkers that may be useful for risk stratification in patients with cerebral aneurysm.

External focus of attention (EFA) and internal focus of attention (IFA) represent commonly used strategies to instruct subjects during exercise. Several studies showed EFA to be more effective than IFA to improve motor performance and learning. To date the role of these strategies on motor performance during finger movement was less studied. The objective of the study was to investigate motor performance, patient’s preference induced by IFA and EFA, and the focus during control condition. Ten healthy right-handed participants performed a finger movement task in control, EFA, and IFA conditions (counterbalanced). Errors, patient’s preference, and type of attentional focus spontaneously adopted during the control condition were recorded. EFA determined less error (p<0.01) compared to control and IFA. Participants preferred EFA against IFA and control condition. In the control group 10% of subjects adopted a purely EFA, 70% of subjects adopted a purely IFA, and 20% of subjects adopted a mixture of the two foci. Our results confirm that EFA is more effective than IFA and control in finger movement task. Due its clinical relevance, the interaction between attention and finger movement should be further investigated.

Background:Ankylosing spondylitis is a chronic systemic inflammatory disease. Inflammation and high levels of serum amyloid A (SAA) protein are predisposing factors for secondary AA amyloidosis. The role of SAA1 gene polymorphisms in AS is not well understood.Objectives:To investigate the association of SAA1 gene polymorphism -13T/C (rs12218) with ankylosing spondylitis and to evaluate the influence of this polymorphism on SAA protein concentration.Methods:123 AS patients (72 males, 51 females; age - M (SD) 37.51 (12.77) years; disease duration - 14.28 (11.22) years; BASDAI – 5.59 (1.13); B27-positive - 111 (90.2%) pts) and 95 gender, age matched healthy individuals (control group) were included in this study. SAA1 gene polymorphism -13T/C was genotyped using allele-specific RT-PCR assay. SAA protein concentration was measured using nephelometry in AS patients.Results:The distribution of genotypes TT, TC and CC differed statistically between AS and control groups (24.4%, 56.1%, 19.5% and 41.1%, 44.2%, 14.7% respectively, χ 2=6.9, p=0.03).The presence of the C allele was associated with the development of AS (OR=1.55 [CI 1.04-2.33], p=0.03). The SAA1 -13T/C polymorphism tended to be associated with SAA protein value in AS patients: TT+TC genotypes -13.8 mg/l [4.2; 91.0], CC genotype -7.8 mg/l [1.6; 29.6], p=0.07. ESR, CRP and BASDAI values did not correlated with SAA1 - 13T/C polymorphism (p=0.6, p=0.4, p=0.4 respectively).Conclusion:The results of our study demonstrated for the first time that SAA1 gene polymorphism -13T/C (rs12218) is associated with susceptibility to AS. It is also shown that this polymorphism can affect the SAA protein level. Our findings need to be verified in AS patients with high levels of SAA protein in various ethnic and population groups.Disclosure of Interests:None declared

Introduction: Increased neutrophils, and stress-induced low lymphocyte levels both indicate changes in the immune system. Blood neutrophil/lymphocyte ratio (NLR) is shown to be a simple, reliable and inexpensive inflammatory indicator that can provide important information on many conditions. Recently, NLR has been proposed as a useful biomarker to predict cardiovascular risk. However, little is known about the role of NLR in patients with intracranial aneurysm (IA). Hypothesis: The purpose of present study was to investigate whether NLR values differ in patients with IA. Methods: The study group consisted of patients with IA who had been admitted to the neurology department from January 2008 to December 2016. A total of 406 patients including 198 patients with unruptured IA, 208 patient with ruptured IA were enrolled in this study. The control group consisted of 420 age, sex-matched healthy adults who had not harbor IA by CTA, MRA, DSA. The baseline NLR was calculated as the ratio of neutrophil count to lymphocyte count. WBC count>12.000 cells per μL or <4.000 cells per μL and high body temperature>38 ° are excluded from the study. Results: The Mean NLR was significantly higher among persons with cerebral aneurysm compared with controls (P < 0.001). The level of NLR in ruptured IA group were found higher compared to unruptured IA and control group (6.1 ± 4.3 vs 2.7 ± 1.5 vs 1.8 ± 1.1, P < 0.001). Other comorbid conditions were balanced between these three groups. Conclusions: We demonstrated that the NLR is an independent predictor of IA patients. In addition, higher NLR is associated with ruptured IA. Unlike many other inflammatory markers and bioassays, NLR are inexpensive and readily available biomarkers that may be useful for risk stratification in patients with cerebral aneurysm. The clinical implications of NLR on IA remain to be established by future investigations. A long term prospective study is needed to clarify this matter.

Abstract Background: This retrospective study aimed to investigate the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) and albumin for 30-day mortality in patients with postoperative acute pulmonary embolism (PAPE).Methods: We retrospectively reviewed the medical records of 101 patients with PAPE admitted from September 1, 2012, to March 31, 2019. The characteristics, surgical information, admission examination data and mortality within 30 days after PAPE were obtained from our electronic medical recording system and follow-up. The associations between the NLR, PLR, and other predictors and 30-day mortality were analyzed with univariate and multivariate analyses. Then, the nomogram including the independent predictors was established and evaluated.Results: Twenty-four patients died within 30 days, corresponding to a 30-day mortality rate of 23.8%. The results of the multivariate analysis indicated that both the NLR and albumin were independent predictors for 30-day mortality in patients with PAPE. The probability of death increased by approximately 17.1% (OR=1.171, 95% CI: 1.073–1.277, P=0.000) with a one-unit increase in the NLR, and the probability of death decreased by approximately 15.4% (OR=0.846, 95% CI: 0.762c–0.939, P=0.002) with a one-unit increase in albumin. The area under the curve of the nomogram was 0.888 (95% CI: 0.812-0.964).Conclusion: Our findings showed that an elevated NLR and decreased albumin were related to poor prognosis in patients with PAPE. The NLR and albumin were independent prognostic factors for PAPE.

Numerous scientific studies have been carried out on the predisposition of the Pro47Ser polymorphism of the TR53 gene to breast cancer in women living in most countries of the world. However, no studies have been conducted on the susceptibility of this Pro47Ser gene polymorphism to breast cancer in Uzbek women. In this article, genotyping of the Pro47Ser polymorphism of the TR53 gene was performed for the first time in 207 Uzbek women. According to the results of our study, the functionally dangerous T allele of the Pro47Ser polymorphism of the TR53 gene was statistically significantly higher than that in healthy donors in patients with breast cancer; (ch2 = 8.2; p = 0.004; OR = 11.2; 95% CI: 1.422-88.38; RR = 10.7; 95% CI: 1.382-82.82). The safe C allele, on the other hand, was more common in the control group than in the main group. The natural S / C genotype was found in the control group with a higher frequency than in the control group. However, the limit of the statistical difference reached a significant level: (ch2 = 8.4; p = 0.004; OR = 0.08; 95% CI: 0.01066-0.676; ch2 = 8.2; p = 0.004; RR = 0.1 ; 95% CI: 0.8489- 0.9723). The S / T genotype of this polymorphism significantly differs in the frequency of occurrence in the main and control groups. Relative risk according to statistical analysis: RR = 10.7; (95% CI: 1.395–82.07) and odds ratio: OR = 11.8; (95% CI: 1.479-93.77). It is known that the minor T allele and the S / T genotype of this polymorphism increase the risk of developing breast cancer by 10.7 times. It should be noted that the unique homozygous genotype of Pro47Ser polymorphism was not identified in patients and control groups studied by T / T. Thus, the T allele and the C / T genotype of the Pro47Ser polymorphism of the TR53 gene are important factors that increase the risk of breast cancer (r <0.05). The C allele and S / S genotype of this polymorphism are reliable protective markers against the development of this pathology. Therefore, we believe that the Pro47Ser polymorphism of the TR53 gene can be used as important genetic markers in determining the likelihood of developing breast cancer.

Abstract. There is a growing interest in embitterment as psychological concept. However, little systematic research has been conducted to characterize this emotional reaction. Still, there is an ongoing debate about the distinctiveness of embitterment and its dimensions. Additionally, a categorical and a dimensional perspective on embitterment have been developed independently over the last decade. The present study investigates the dimensions of embitterment by bringing these two different approaches together, for the first time. The Bern Embitterment Inventory (BEI) was given to 49 patients diagnosed with “Posttraumatic Embitterment Disorder (PTED)” and a matched control group of 49 patients with psychological disorders with other dominant emotional dysregulations. The ability to discriminate between the two groups was assessed by t-tests and Receiver Operating Characteristic Curves (ROC curve analysis). PTED patients scored significantly higher on the BEI than the patients of the control group. ROC analyses indicated diagnostic accuracy of the inventory. Further, we conducted Confirmatory Factor Analyses (CFA) to examine the different dimensions of embitterment and their relations. As a result, we found four characteristic dimensions of embitterment, namely disappointment, lack of acknowledge, pessimism, and misanthropy. In general, our findings showed a common understanding of embitterment as a unique but multidimensional emotional reaction to distressful life-events.
