Abstract
INTRODUCTION Neutrophil-lymphocyte ratio (NLR), a simple, inexpensive, and effective biomarker associated with various inflammatory and neoplastic diseases, has become the focus of attention in recent years. Nevertheless, it has not been adequately studied in dyspeptic patients with peptic ulcer (PU) and without PU, i.e., patients with non-ulcer dyspepsia (NUD). MATERIALS AND METHODS The population of this retrospective study consisted of patients with dyspeptic complaints who underwent esophagogastroduodenoscopy between April 2023 and June 2023. A total of 180 patients included in the study sample were categorized into two groups based on the endoscopy results: patients without PU or NUD patients (Group 1) and those with PU (Group 2). Age, gender and pre-procedural NLR data, upper gastrointestinal endoscopy results, and the presence of Helicobacter pylori (Hp) in endoscopic biopsy information were recorded for all patients. RESULTS Of the 180 patients, 140 were diagnosed with NUD (Group 1), and 40 were diagnosed with PU (Group 2). There was a significant difference between Groups 1 and 2 in terms of NLR (Group 1: 2.5±1.8 vs. Group 2: 3.6±3.7, p=0.014). There was also a significant difference in NLR between Group 1 and Group Gastric Ulcer (p=0.030) but not between Group 1 and Group Duodenal Ulcer (p=0.064). Rates of patients with positive Hp test results were 25% and 32.5% in Groups 1 and 2, respectively, indicating a significant difference between the groups (p=0.026). CONCLUSION The NLR measured in patients who presented with dyspeptic complaints was found to be significantly higher in PU patients than in NUD patients. The elevated NLR levels were even more evident in PU patients with GU compared to PU patients with DU.

Abstract
BACKGROUND Immune checkpoint blockade (ICB) treatment may induce durable disease remission, but only in a minority of patients with cancer. One important question is how to identify patients who may benefit from ICB treatment. ICB treatment relies on unleashing patients' pre-existing immune responses. Focusing on the key components of immune response, this study proposes the neutrophil-to-lymphocyte ratio (NLR) as a simplified indicator of patients' immune status to predict ICB treatment outcomes. METHODS This study analyzed a large pan-cancer cohort of 16 cancer types, including 1714 patients with cancer who received ICB treatment. Clinical outcomes in response to ICB treatment were measured by overall survival (OS), progression-free survival (PFS), objective response rate, and clinical benefit rate. The non-linear relationships of NLR with OS and PFS were investigated by a spline-based multivariate Cox regression model. A total of 1000 randomly resampled cohorts were bootstrapped to estimate the variability and reproducibility of NLR-related ICB responses. RESULTS By interrogating a clinically representative cohort, this study revealed a previously unreported finding that the pretreatment NLR levels were associated with ICB treatment outcomes in a U-shaped dose-dependent manner rather than a linear manner. An NLR range between 2.0 and 3.0 was remarkably associated with optimal ICB treatment outcomes, including increased patient survival, delayed disease progression, improved treatment response, and significant clinical benefit. Comparatively, either decreasing (< 2.0) or increasing (>3.0) NLR levels were indicators of worse ICB treatment outcomes. Furthermore, this study presents a comprehensive landscape of NLR-related ICB treatment outcomes across different patient populations defined by demographics, baseline characteristics, treatment, cancer-type-specific ICB responsiveness, and individual cancer type. CONCLUSIONS The NLR range from 2.0 to 3.0 might indicate an optimal balance between innate (neutrophils) and adaptive (lymphocytes) immune responses that potentiates antitumor immunity, which was observed in only 18.6% of patients. A majority of patients showed decreasing NLR (<2.00; 10.9% patients) or increasing NLR (>3.00; 70.5% patients), representing two distinct types of immune dysregulation associated with ICB resistance. This study translates routine blood tests into a precision medicine-based approach to immunotherapy, with important implications for clinicians in clinical decision-making as well as for regulatory agencies in drug approvals.

Abstract
Necrotizing fasciitis is a rapidly progressive infection with a high mortality rate. Pathogens evade the host containment and bactericidal mechanisms by hijacking the coagulation and inflammation signaling pathways, leading to their rapid dissemination, thrombosis, organ dysfunction, and death. This study examines the hypothesis that measures of immunocoagulopathy upon admission could aid in the identification of patients with necrotizing fasciitis at high risk for in-hospital mortality. Methods Demographic data, infection characteristics, and laboratory values from 389 confirmed necrotizing fasciitis cases from a single institution were analyzed. A multivariable logistic regression model was built on admission immunocoagulopathy measures (absolute neutrophil, absolute lymphocyte, and platelet counts) and patient age to predict in-hospital mortality. Results The overall in-hospital mortality rate was 19.8% for the 389 cases and 14.6% for the 261 cases with complete measures of immunocoagulopathy on admission. A multivariable logistic regression model indicated that platelet count was the most important predictor of mortality, followed by age and absolute neutrophil count. Greater age, higher neutrophil count, and lower platelet count led to significantly higher risk of mortality. The model discriminated well between survivors and non-survivors, with an overfitting-corrected C-index of 0.806. Conclusions This study determined that measures of immunocoagulopathy and patient age at admission effectively prognosticated the in-hospital mortality risk of patients with necrotizing fasciitis. Given the accessibility of neutrophil-to-lymphocyte ratio and platelet count measurements determined from a simple complete blood-cell count with differential, future prospective studies examining the utility of these measures are warranted. Level of Evidence Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Objective Inflammatory Bowel Diseases (IBDs) are chronic inflammatory conditions of the gastrointestinal tract, including Crohn's disease (CD) and ulcerative colitis (UC). Developing methods for effective screening and diagnosis is extremely needed. Accordingly, this study aims to evaluate the potential of immune cells ratios in the diagnosis of IBD. Methods This case-control study includes data from Jordan University Hospital (JUH) medical records for IBD patients with age- and gender-matched healthy controls. Results This study included 46 participants, of which 56.52% had IBD, 54.35% were males, with insignificant differences in sex, age, and body mass index (BMI) between IBD patients and controls (p>0.05). In the CD group, the variables with the highest sensitivity and specificity (HSS) were neutrophil-to-lymphocyte (NLR) (75%, 80%) and platelet-to-lymphocytes (PLR) (75%, 90%), in UC group; mean corpuscular hemoglobin (MCH) (80%, 80%). In CD group, the combinations giving the HSS were PLR+NLR (76%, 90.9%), C-reactive protein (CRP)+PLR (76%, 90.9%), and CRP+NLR (73.07%, 90%). In UC group, the combinations giving the HSS were erythrocyte sedimentation rate (ESR)+PLR (76.9%, 100%), PLR+MCH (74.07%, 100%), PLR+CRP (71.42%, 100%), and PLR+NLR (71.42%, 100%). Regression analysis identified five different combinations of significance in the diagnosis of CD and UC. Higher Youden's index was used and defined the most beneficial clinical combinations as NLR+PLR and CRP+PLR for CD, whereas ESR+PLR for UC. Conclusion Implications to our study include the clinical application of immune cell ratios, inflammatory markers, and their different combinations along with patients' history and physical examination findings for easier, faster, and more cost-effective diagnosis of IBDs.

Abstract
H. pylori is involved in the development of 80% of gastric cancers and 5.5% of all malignant conditions worldwide. Its persistence within the host’s stomach causes chronic inflammation, which is a well-known hallmark of carcinogenesis. A wide range of cytokines was reported to be involved in the initiation and long-term persistence of this local and systemic inflammation. IL-8 was among the first cytokines described to be increased in patients with H. pylori infection. Although, this cytokine was initially identified to exert a chemoattracting effect that represents a trigger for the activation of inflammatory cells within H.-pylori-infected mucosa, more recent studies failed in encountering any association between IL-8 and H. pylori infection. IL-6 is a multifunctional, pleiotropic and multipotent cytokine involved in mediating the interaction between innate and adaptive immunity with a dichotomous role acting as both a proinflammatory and an anti-inflammatory cytokine depending on the signaling pathway. IL-1α functions as a promoter of angiogenesis and vascular endothelial cell proliferation in gastric carcinoma since it is closely related to H.-pylori-induced inflammation in children. IL-1β is an essential trigger and enhancer of inflammation. The association between a low IL-1β level and an increased TNF-α level might be considered a risk factor for peptic ulcer disease in the setting of H. pylori infection. IL-10 downregulates both cytotoxic inflammatory responses and cell-mediated immune responses. H. pylori uses the immunosuppressive role of IL-10 to favor its escape from the host’s immune system. TGFβ is a continuous inflammatory mediator that promotes the adherence of H. pylori to the host’s cells and their subsequent colonization. The role of H.-pylori-induced inflammatory responses in the onset of gastric carcinogenesis seems to represent the missing puzzle piece for designing effective preventive and therapeutic strategies in patients with H.-pylori-associated gastric cancer.

Abstract
The link between chronic gastritis and chemosensory receptors is considered promising for disease prediction and treatment. The transient receptor potential melastatin member channel 5 (TRPM5) is an ion channel and may be a chemosensor in the gastrointestinal tract. Trace elements and minerals involved in many protein structures can change ion channel activity. Our study aimed to determine trace element and mineral levels according to TRPM5 Asn235Ser missense polymorphism distributions in patients with H. pylori (+) and (-) gastritis and to uncover their possible association with disease pathogenesis. In 109 volunteer patients diagnosed with gastritis [64 H. pylori (+), 45 H. pylori (-)], TRPM5 (Asn235Ser) polymorphism was detected by Kompetitive Allele-Specific PCR method (KASP), but no difference was found between the groups. There are differences between the serum trace element (Se, Zn, Cu, Mg, and Cu/Zn) levels of the two groups. High serum Se and Cu/Zn ratios were detected in H. pylori (+) patients. Cu/Zn ratio can be used as a marker of bacterial inflammation. The amount of Se was found to be statistically significant in the serums of H. pylori (+) patients carrying TT and CT genotype, while the amounts of Zn, Cu, and Mg were found as significant of H. pylori (-) patients. The relationship of Se with the H. pylori needs to be investigated further. In addition, H. pylori (+) patients have a significantly higher neutrophils/lymphocytes ratio (NLR) compared to those with H. pylori (-) NLR can be used as an indicator of inflammation.

Abstract
The aim of this study was to define the relationship between several environmental, laboratory, and genetic factors, i.e., TLR2 and NLRP3 polymorphisms, and Helicobacter pylori (H. pylori) infection in children, by comparing three different groups of pediatric subjects: H. pylori-induced gastritis, non-H. pylori gastritis, and healthy controls. Our final study sample included 269 children, which were divided into three groups according to the histopathological exam: group 1 with 51 children with H. pylori-induced gastritis, group 2 with 103 children with H. pylori-negative gastritis, and group 3 (control group) with 115 children without any histopathological changes. All children underwent a thorough anamnesis, clinical exam, laboratory tests, and upper digestive endoscopy with gastric biopsy for rapid urease test, histopathological exam, and genetic analysis of TLR2 rs3804099, TLR2 rs3804100, and NLRP3 rs10754558 gene polymorphisms. We noticed a significant association between living conditions and the type of gastritis (p < 0.0001). Both rapid urease and serological tests were significantly associated with the presence of H. pylori (p < 0.0001). The CT variant genotype of TLR2 rs380499 was significantly associated with neutrophil count (p = 0.0325). We noticed a significant association between the CC variant genotype of NLRP3 rs10754558 and leucocytes, neutrophils, eosinophils, as well as ALT (p = 0.0185, p = 0.0379, p = 0.0483, p = 0.0356). Based on these findings, we state that poor living conditions and rural areas represent risk factors for H. pylori infection. The rapid urease test is a reliable diagnostic tool for this infection. CT and TT carriers of TLR2 rs3804099, as well as CC carriers of NLRP3 rs10754558, might display a more severe degree of systemic inflammation.

Abstract
Introduction Deep neck space infections (DNSIs) are a group of infective suppurative diseases involving deep neck spaces and cervical fascia. Necrotising and septic evolutions are rare, but severe complications can dramatically affect the prognosis and should be promptly managed. Clinical examination often has low sensitivity, although instrumental diagnosis may delay te treatment. We investigated two laboratory tools, LRINEC (Laboratory Risk Indicator for the Necrotizing fasciitis) and NLR (neutrophil to lymphocyte ratio), in the expectation to find a rapidly available predictive indicator that may help in distinguishing necrotising complications and/or systemic septic involvement. Methods A retrospective observational cohort study was performed on 118 patients who had underwent surgical treatment for DNSIs at our Surgical Unit. LRINEC, NLR and the product LRINEC x NLR were calculated. Results Statistical analysis showed that these scores may have utility in rapidly predicting the risk of necrotising fasciitis and systemic involvement at an early diagnostic stage. Conclusions Further studies with a larger cohort may be necessary in order to increase the sensitivity and specificity.

Abstract
BACKGROUND Innate immunity was found to be associated with both persistence of Helicobacter pylori (H. pylori) infection and increased risk of gastric cancer.
AIM To identify the risk factors associated with H. pylori infection and to establish the role of TLR9 rs352140 in suppressing or promoting inflammation related to this infection in children.
METHODS We performed a study of 155 children with digestive symptoms, who were divided into two groups according to the histopathological exam: Group 1 – 48 children with H. pylori-induced chronic gastritis, and Group 2 – control group.
RESULTS Rural area and poor living conditions were significantly associated with H. pylori chronic gastritis (P = 0.0042/P < 0.0001). Both positive immunoglobulin A anti H. pylori and the rapid urease test were significantly associated with H. pylori infection (P < 0.0001). Significantly higher values of leukocytes and neutrophils within the peripheral blood were found in children with H. pylori chronic gastritis (P = 0.111/P = 0.284). We found a significant positive correlation between the variant TT genotype of TLR9 rs352140 polymorphism and both leucocytes and neutrophils (P = 0.0225/P = 0.0292).
CONCLUSION Variant TT genotype carriers of the TLR9 rs352140 gene polymorphism might have a more severe degree of inflammation.

Abstract
OBJECTIVES Obesity and related diseases have become one of the most important health problems in the modern age. In addition to its clinical use in the treatment of obesity, bariatric surgery reduces obesity-induced inflammation. Neutrophil-lymphocyte ratio (NLR) is a cheap and easily attainable inflammatory marker. The purpose of this study is to show the effect of bariatric surgery on NLR at preoperative and postoperative 3rd, 6th, and 12th months after SG. METHODS 298 patients, who underwent sleeve gastrectomy (SG) in general surgery clinic between 2015 and 2017, were included in the study. We excluded the patients younger than 18 years old, and did not have any inflammatory, infectious, hematological, and comorbide diseases such as diabetes mellitus, cardiovascular diseases, ischemic heart disease, hypertension, renal insufficiency, cancer, and respiratory problems like asthma, obstructive sleep apnea syndrome. We evaluated the levels of NLR at preoperative and postoperative 3rd, 6th, and 12th months visits. RESULTS There were a total of 298 adult patients (age: mean 38.6, minimum 18, maximum 69 years old). Of whom 247 were female (82.9%) and 51 were male (17.1%). We found that NLR levels decreased significantly at 3rd, 6th, and 12th month visits after SG (p<0.001). CONCLUSIONS We concluded that NLR levels decrease after surgery in a proportional reduction in adipose tissue. The decrease in NLR levels may also be associated with the protective effects of sleeve gastrectomy against low-grade inflammation-related diseases.

Abstract
Atherosclerotic cardiovascular diseases (ASCVD) are the major cause of mortality worldwide. Despite the continuous progress in ASCVD therapy, the residual risk persists beyond the management of traditional risk factors. Several infections including Helicobacter pylori infection, periodontal disease, and viral infections are associated with the increased risk of ASCVD, both directly by damage to the heart muscle and vasculature, and indirectly by triggering a systemic proinflammatory state. Hence, beyond the optimal management of the traditional ASCVD risk factors, infections should be considered as an important non-classical risk factor to enable early diagnosis and appropriate treatment. Here, we summarized the currently available evidence regarding the role of inflammation in ASCVD and the association between the particular infections and pathogens (Helicobacter pylori, periodontal disease, pneumonia, Cytomegalovirus, Human immunodeficiency virus, Herpes simplex virus, and severe acute respiratory syndrome coronavirus 2) on the development and progression of ASCVD. We also speculated about the potential therapeutic implications of the anti-inflammatory and anti-infective drugs on ASCVD outcomes, including drugs routinely administered in patients with ASCVD (statins, P2Y12 receptor inhibitors, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers) and novel strategies aiming at residual risk reduction (colchicine, anti-cytokine drugs, and methotrexate). Considering the emerging association between infections and ASCVD, it is crucial to determine the possible advantages of infection prevention and treatment in patients with ASCVD.

Abstract
Background: The indications for endoscopic submucosal dissection (ESD) for gastric cancer are based on preoperative histological assessment; however, examination of tissue biopsy is not always reliable as only a limited portion of the lesion can be obtained. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are markers of inflammatory response and are potentially associated with the grade of malignancy in gastric cancer. We aimed to investigate the association between NLR and PLR and the histology of gastric cancer. Methods: This study included 218 patients who underwent ESD for gastric cancer. The relationship between NLR/PLR and histological diagnosis was investigated. Results: Patients with adenocarcinomas showed significantly higher NLR and PLR than those with adenomas (p < 0.001 and p < 0.05, respectively). Further, patients with undifferentiated adenocarcinoma showed a significantly higher NLR (p < 0.05) than those with differentiated adenocarcinoma. Conclusion: This study suggests that NLR could be a useful marker for assessing early gastric cancer.

Abstract
Recent studies have shown a correlation between Helicobacter pylori (H. Pylori) infection and the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR). The aim of this study was to investigate the relationship between H. Pylori infection and hematimetric indices in patients with dyspepsia symptoms. Overall, 448 patients who underwent gastroscopy were analyzed retrospectively. Histopathological evaluation of biopsies according to H. pylori presence was classified as H. Pylori positive and negative groups, which are analyzed in relation with hematimetric indices. NLR and PLR measurements did not show a statistically significant difference between H. pylori negative and positive groups (p > 0.05). NLR revealed a negative correlation between hemoglobin (HGB), iron, and ferritin measurements in the correlation analysis of the H. Pylori positive group (r = −0.133, p = 0.031; r = −0.270, p = 0.002; r = −0.162, p = 0.032). Again, with PLR, there was a negative correlation between HGB, mean corpuscular volume (MCV), iron, and ferritin measurements (r = −0.310, p = 0.001, r = −0.187, p = 0.002, r = −0.335, p = 0.001; r = −0.290; p = 0.001). The results of our study do not reveal an association between H. pylori presence and inflammatory response, which is evaluated by NLR and PLR measurements in patients with dyspepsia. However, low serum iron and ferritin values of H. pylori-positive patients suggest the effect of H. pylori on iron metabolism.

Abstract
Non-invasive biomarkers, such as neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios, may predict inflammation in various disorders, including gastritis, according to recent data. Nevertheless, various studies reported an association between Helicobacter pylori (H pylori) and immune thrombocytopenia in both adults and pediatric patients. The objective of our study was to evaluate the impact of pediatric gastritis, caused or not by H pylori infection on erythrocytes, their parameters, thrombocytes, mean platelet volume, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR).We performed a prospective, case-control study on 151 patients aged between 1 and 17 years who presented with chronic dyspeptic symptoms. An upper digestive endoscopy with gastric biopsies and a complete blood count was performed in each case.Control group consisted of 67 patients with normal histological findings, while the two study groups were divided into group 1-H pylori-induced gastritis (31 patients) and group 2-non-H pylori-induced gastritis (53 patients). Children from the rural area were more likely to develop both types of gastritis (P < .01). No significant difference was found between either of the study groups and control group in terms of platelets, mean platelet volume, NLR and PLR (P > .05). However, significantly higher values of lymphocytes were associated with non-H pylori-induced gastritis (P < .01). Comparison of the two study groups did not reflect any significant differences in terms of hematological parameters. When assessing these constants in relation to gastritis severity, severe gastritis led to a compelling decrease in hemoglobin (Hb) and hematocrit (Htc) levels. The comparison of parameters between severe, moderate, and mild gastritis did not reveal any significant results.Childhood and adolescent gastritis does not produce a significant effect upon platelet counts, their mean volume, PLR or NLR, according to our study. An important increase in lymphocyte count might predict non-H pylori pediatric gastritis. Moreover, severe gastritis might result in an important decrease in Hb and Htc levels.

Abstract
Helicobacter pylori (H. pylori) infection is on the rise as a cause of immune thrombocytopenia (ITP). It has been suggested that platelet recovery can be achieved following successful microbial eradication, although, the exact pathophysiology has yet to be fully elucidated. This study evaluated the long-term effects of H. pylori eradication monotherapy on platelet count recovery in patients with ITP. H. pylori eradication was analysed in 61 ITP patients. Patients who maintained a complete response (CR) for more than six months were classified as sustained responders (SR). The prevalence of H. pylori infection was 54.3% (75/138), and the success rate of eradication with first-line therapy was 71.4% (35/49). Patients who had achieved a CR at 2 months maintained a higher platelet count thereafter. At 1 year following eradication, platelet counts had increased 2.78 times in the eradicated group, 1.36 times in the sustained infection group, and 1.33 times in the no infection group compared with the baseline (P = 0.016).

Abstract
BACKGROUND TLR4 is involved in H. pylori lipopolysaccharide recognition and its SNPs might be related to increased risk of developing premalignant conditions and gastric cancer. The objectives of the study were to evaluate the associations between both TLR4 rs4986790 and rs4986791 gene polymorphisms and H. pylori infection in children with gastritis. METHODS We performed a cross-sectional study on 150 children admitted in a Tertiary Centre from Romania, between March 2016 and July 2018 in order to evaluate them regarding demographic, endoscopic, histopathological and TLR4 gene polymorphisms. RESULTS Our final sample consisted of 50 children with H.pylori associated gastritis (group 1-Ghp group) and 97 children with gastritis without H.pylori infection (group 2). Poor socioeconomic status was a significant risk factor for H.pylori infection. We found no significant differences regarding the clinical symptoms and laboratory parameters between the two groups. Concordant results were found between the histopathological exam and rapid urease test. Variant genotypes of TLR4rs4986790 and TLR4rs4986791 gene polymorphisms acted as protective factors against H. pylori infection, without statistical significance. CONCLUSIONS The variant genotype of the TLR4 gene polymorphisms might be protective factors for H.pylori infection, while socioeconomic status is an risk factor for H. pylori infection. Urease test is a usefull diagnostic tool for H. pylori infection.

Abstract
Background Acute venous thromboembolism (VTE) refers to deep venous thrombosis (DVT) of the extremities or pulmonary embolism (PE), or to both. Reliable imaging is not always available making a serologic diagnosis, or biomarker, highly desirable. Objective This study aimed to examine the role of neutrophil‐lymphocyte ratio (NLR), platelet‐lymphocyte ratio (PLR), and mean platelet volume (MPV) in detection patients with acute VTE. Methods A total of 327 patients with initial diagnosis of acute VTE who were admitted to Ziv hospital were evaluated. Of them, 272 patients with definitive diagnosis of VTE, and 55 patients without VTE were used as control group. Complete blood count (CBC), measurements of NLR, MPV, and PLR were determined at admission. Results Patients with VTE were older than controls (62 ± 18.9 vs 55.4 ± 15.1 years, respectively, P = .03). Female gender was predominant in the two groups. In the study group, 178/272 (66%) had DVT, 84/272 (31%) had pulmonary embolism (PE), and the rest had DVT and PE. NLR, MPV, and PLR were found to be significantly elevated in acute VTE compared to control (P < .001, P = .008, P = .014, respectively). A ROC curve analysis of NLR and MPV for predicting acute VTE was performed which found a cut‐off value of 5.3 for NLR, an area under curve of (0.67 (0.60‐0.75), P < .001, with a sensitivity of 69% and specificity of 57%. and a cut‐off value of 8.6 for MPV, an area under curve of (0.61 [0.53‐0.68], P = .014, with a sensitivity of 52% and specificity of 67%. Multivariate logistic regression model found that NLR (OR 1.2, 95% CI [1.01‐1.4], P = .041) and MPV (OR 1.5, 95%CI [1.07‐2.12], P = .5) were associated with acute VTE. Conclusions Neutrophil‐lymphocyte ratio and MPV could be beneficial predictors for the early detection of potential acute VTE.

Abstract
OBJECTIVES Previous evidence suggested Helicobacter pylori (H. pylori) promoted tumorigenesis by inducing inflammation in gastric premalignant disease. Whether this organism affected the development of head and neck precancerous lesion remains unknown. We performed this study to assess the prognostic impact of H. pylori infection on patients with laryngeal precancerous lesion. METHODS In this prospective study, 41 enrolled patients with laryngeal precancerous lesion were arranged into H. pylori-positive group (n=16) and H. pylori-negative group (n=25). Two poor outcomes were recurrence and malignant transformation. Prognostic impact of H. pylori infection was analyzed using the Univariate Cox proportional hazard model and Cochran-Mantel-Haenszel test. We also analyzed the prognostic value of systemic inflammation-based markers. RESULTS During a median follow-up of 32.9 months, recurrence developed in 8 patients in the H. pylori positive group and 5 patients in the H. pylori negative group (50.0% vs. 20.0%, P=0.026, Log-rank test). Malignant transformation developed in 4 patients in the H. pylori positive group and no patients in the H. pylori negative group (25.0% vs. 0.0%, P=0.005, Log-rank test). H. pylori positive group had a significant higher malignant transformation rate after stratifying on the observed covariates. There was no significant difference of recurrence rate in two groups stratified with laryngopharyngeal reflux, size of lesion, and pathological type (Cochran-Mantel-Haenszel test). The basal levels of lymphocyte counts and neutrophils to lymphocytes ratio were significantly different in patients with H. pylori infection. Moreover, the receiver operating characteristic curve analysis revealed a predictive value of lymphocyte counts and neutrophils to lymphocytes ratio for poor outcomes (areas under the curve, 0.658 and 0.651, respectively). CONCLUSION The data demonstrate a malignant transformation-relevant role of H. pylori in laryngeal precancerous lesion. H. pylori infection combined with laryngopharyngeal reflux, size of lesion, and pathological type might relate to recurrence of laryngeal precancerous lesion. And changes of lymphocyte counts and neutrophils to lymphocytes ratio associated with H. pylori infection might deserve as predictive indicators for poor prognosis of laryngeal precancerous lesion.

Abstract
Objective: Tumor response to neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients is a predictor for overall survival. The aim of our study was to determine a relationship between the neutrophil to lymphocyte ratio (NLR) prior to NAC, BC subtypes and the probability of a pathologic complete response (pCR). Materials and Methods: Medical records were collected retrospectively from Centro de Cancer at Red Salud UC-Christus. Clinical data collected included peripheral blood cell counts, BC subtype at diagnosis and the pathology report of surgery after chemotherapy. Results: A total of 88 patients were analyzed. Approximately, a 25% had a pCR, and displayed a significant correlation between BC subtype and pCR (p= 0.0138 Chi2); this was more frequent in epidermal growth factor receptor type 2 (HER2) enriched subtype patients (54%). Luminal B BC patients with a pCR had significantly lower NLR levels (t test, p= 0.0181). Conclusions: HER2-enriched tumors had a higher probability of pCR. In Luminal B tumors, NLR had a statistically significant relationship with the probability of pCR. In this subtype, NLR could be a useful biomarker to predict tumor response to NAC. Further studies including other clinical parameters for systemic inflammation such as platelet counts, intratumoral NLR or body mass index could help identify patients that would get the most benefit from NAC.

Abstract
Neutrophil to lymphocyte ratio (NLR) is a simple, noninvasive, inexpensive inflammatory marker that can useful in the assessment of inflammatory activity, especially in pediatric ages. The aim of our study was to establish correlations between the presence of Helicobacter pylori (HP) proved histologically and NLR in children.A prospective, case-control study was performed on 137 pediatric patients aged between 1 and 18 years, admitted in a Pediatric Tertiary Hospital from Romania, between April 2016 and January 2018. According to the histologic examination, the children were divided into 2 groups: group 1: 50 children with HP infection, and group 2: 87 children without any pathologic findings.The mean age for the study group was 12.86 ± 3.796 years, whereas for control group, it was 12.10 ± 3.879 years (P = .3001). HP infection was significantly more frequent among children from rural area (P = .0089). Epigastric pain and loss of appetite were significantly associated with HP infection (P = .0350 /P = .0281). We noticed that the leukocyte and neutrophil counts were significantly higher in group 1 (P = .0076/P = .0306). We did not find any significant statistical differences between the 2 groups in terms of lymphocytes, erythrocyte sedimentation rate, and NLR or other assessed laboratory parameters. Regarding the IgA antibodies anti-HP and rapid urease test, they were both significantly associated with histologically confirmed HP infection (P < .0001).Even though, we did not identify significant differences in term of NLR between HP-induced gastritis children and healthy controls, the mean NLR values were higher HP-positive patients.

Abstract
PURPOSE To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. METHODS A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in the study. On endoscopy, five gastric biopsies were taken according to Modified Sydney protocol, which were stained with hematoxylin & eosin and Giemsa. RESULTS HP infection was found in 28.6% of patients, being significantly more common in specimens with acute and chronic inflammatory activity. Mucosal atrophy, intestinal metaplasia, and dysplasia were found in 20.2%, 18.8% and 2.7% of biopsy specimens. Mean hs-CRP was 1.9±1.6 mg/dl for males and 2.2±1.9 mg/dl for females. hs-CRP average were significantly higher in patients with severe acute inflammation (p:0.049), in patients with severe chronic inflammation (p:0.015) and in those with HP (p: 0.001) . The severity of HP infection increased significantly with the increased degree of acute inflammation, chronic inflammation and hs-CRP level (p=0.001 for both). CONCLUSION Serum hs-CRP level increases in patients with chronic gastritis, it could be an indicator of severity of acute or chronic mucosal inflammation, and presence of HP infection. Therefore, hs-CRP may aid the diagnosis of chronic gastritis, but it is not associated with pre-cancerous lesions.

Abstract
OBJECTIVES To assess the utility of the neutrophil:lymphocyte (NLR), lymphocyte:monocyte (LMR) and platelet:lymphocyte ratios (PLR) as infection biomarkers. METHODS PubMed/MEDLINE, Embase and Cochrane databases were searched to identify eligible articles. Studies of diagnosis, severity or outcome were included. PROSPERO systematic review registration CRD42017075032. RESULTS Forty studies were included, reporting on bacterial and viral infections, malaria, and critical illness due to sepsis. Ten studies reported an association of higher NLR with bacteraemia, supported by meta-analysis of patient-level data (five studies, n = 3320; AUC 0.72, p<0.0001) identifying a cut-off of >12.65. Two studies reported an association with lower LMR and diagnosis of influenza virus infection in patients with respiratory tract infection. Meta-analysis of patient-level data (n = 85; AUC 0.66, p = 0.01) identified a cut-off of ≤2.06. The directionality of associations between NLR and outcomes in heterogeneous cohorts of critically ill adults with sepsis varied. Potential clinical utility was also demonstrated in pneumonia (NLR), pertussis (NLR), urinary tract infection (NLR), diabetic foot infections (NLR) and Crimean Congo Haemorrhagic Fever (PLR). Longitudinal measurement of LMR during respiratory virus infection reflected symptoms and NLR during sepsis and bacteraemia predicted mortality. CONCLUSIONS Peripheral blood leucocyte ratios are useful infection biomarkers, with the most evidence related to diagnosis of bacteraemia and influenza virus infection. In critical illness due to sepsis, a signal towards an association with NLR and outcomes exists, and NLR should be evaluated in future stratification models. Longitudinal measurement of ratios during infection could be informative. Overall, these biomarkers warrant further recognition and study in infectious diseases.

Abstract
BACKGROUND A positive circumferential resection margin (CRM) may result in local recurrence (LR), but the significance remains controversial. We attempted to utilize the lymphocyte ratio (LYMR), neutrophil-lymphocyte ratio (NLR), tumor-infiltrating lymphocyte (TIL) count, and their combinations (TIL-LYMR/TIL-NLR) in predicting LR after rectal resection. METHODS Patients with rectal cancer who underwent curative resection between January 2016 and December 2018 were enrolled. Biopsy samples and data from the blood tests of 124 patients with rectal cancer who underwent curative resection were retrospectively obtained. Patients were divided into 2 groups: LR group and non-local recurrence (nLR) group. CD8 + TILs were immunostained using an antibody against CD8. The density of TILs was defined as the number of positive CD8 lymphocytes per square millimeter and was then graded as either high or low (cutoff = 80/mm). The count of LYMR and NLR was also graded as either high or low. The associations between TILs, LYMR, NLR, and their combinations (TIL-LYMR/TIL-NLR) were evaluated. RESULTS With a median follow-up of 24.4 months, TIL-LYMR showed a positive correlation with LR (P = .001), but not with the CD8 + TIL count (P = .215) or TIL-NLR count (P = .638). Among inflammatory and immune markers variables, univariate analysis revealed that gender, CD8 + TIL count, and TIL-NLR count were associated with anastomotic leakage (P = .001, P = .014, and P = .036, respectively). In multivariate analysis, TIL-LYMR remained an independent predictor of LR (OR = 8.918, CI = 1.124-70.747, P = .038). We also showed that gender associated with anastomotic leakage in rectal cancer (OR 5.429; 95% CI 1.885-15.637; P = .002). CONCLUSION In this study, our data indicate that absence of CD8 + T-cell infiltration in CRM may influence LR. These parameters may help identify LR provide additional information for therapeutic decision-making.

Abstract
AIM To assess the value of each index of routine blood test in the early diagnosis of gastric cancer (GC), and investigate the effect of Helicobacter pylori (H. pylori) infection on routine blood indexes.
METHODS A total of 223 inpatients or hospitalized patients who underwent gastroscopy from September 2016 to September 2017 were selected and divided into four groups according to gastroscopic and pathological results, including 58 patients with chronic superficial gastritis (CSG), 59 patients with chronic atrophic gastritis (CAG), 52 patients with high-grade intraepithelial neoplasia (HIN), and 57 patients with GC. Red blood cell distribution width (RDW), platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), white blood cell count (WBC), lymphocyte count (LYMP), neutrophil count (NR), neutrophil count to lymphocyte ratio (NLR), and platelet count to lymphocyte ratio (PLR) were compared in different groups, and the sensitivity and specificity of each index for diagnosis of GC were calculated. The effect of H. pylori infection on routine blood indexes was also analyzed.
RESULTS LYMP and MPV gradually decreased and RDW, NLR, and PLR gradually increased from CSG to CAG, HIN, and GC. RDW, MPV, LYMP, NLR, and PLR were all significantly different between the CSG group and GC group (P < 0.05). In detecting GC, the sensitivities of RDW, MPV, LYMP, NLR, PLR, and NC were 82.5%, 80.7%, 84.2%, 84.2%, 71.9%, and 45.6%, respectively, and the specificities were 72.4%, 55.2%, 82.8%, 91.0%, 89.7%, and 89.7%, respectively. The positive rates of H. pylori in the CSG group, CAG group, HIN group, and GC group were 63.7%, 62.5%, 63.5%, and 66.7%, respectively. In the CSG group, PLT, WBC, and NR were significantly higher in H. pylori positive patients than in H. pylori negative patients (P < 0.05). There were no significant differences in blood routine indexes between H. pylori positive and H. pylori negative patients in the CAG, HIN, and GC groups (P > 0.05).
CONCLUSION RDW, PLT, MPV, LYMP, NLR, and PLR can be used in the early diagnosis of GC. H. pylori infection can lead to systemic inflammatory reactions. Early eradication of H. pylori is beneficial to the prevention of GC.

Abstract
Objectives The systemic status and local immune status, as determined by the neutrophil–lymphocyte ratio (NLR) or the lymphocyte ratio (LYMR) and tumor-infiltrating lymphocyte (TIL) count, respectively, have been suggested as predictors of the tumor response to neoadjuvant chemoradiotherapy (nCRT) in rectal cancer, although the utility of these measures remains controversial. We aimed to investigate the values of the LYMR, NLR and TIL count and their combinations (TIL–LYMR/TIL–NLR) in predicting pathologic complete response (pCR) after nCRT. Patients and methods Pretreatment biopsy samples and data from the blood tests of 92 patients with rectal cancer who underwent curative resection after nCRT were retrospectively obtained. CD8+ TILs were immunostained using an antibody against CD8. The density of CD8+ TILs was recorded as the number of CD8+ T cells per square millimeter, and the results were classified as either “high” or “low”. The LYMR and NLR were calculated using pretreatment blood test data and categorized into either “high” or “low” groups. TIL–LYMR was graded as “low,” “mid” or “high” when neither, one or both the CD8+ TIL count and LYMR were “high,” respectively. TIL–NLR was graded similarly. The associations between TILs and LYMR, NLR and their combinations (TIL–LYMR/TIL–NLR) were evaluated. Results pCR was significantly associated with a high LYMR, a low NLR and increased chemotherapy cycles (P=0.039, P=0.043 and P=0.015, respectively), but not with the CD8+ TIL count or carcinoembryonic antigen (CEA) level (P=0.100 and P=0.590, respectively). Additionally, 40% of patients with high LYMR and 40.7% with low NLR achieved pCR, whereas only 19.7% with low LYMR and 20.3% with high NLR did so. When the combinations were assessed, TIL–LYMR showed a positive correlation with pCR (P=0.038), while no association between TIL–NLR and pCR was found (P=0.916). In multivariate analysis, TIL–LYMR remained an independent predictor of pCR (odds ratio [OR]=1.833, 95% confidence interval [CI]=1.069–3.142, P=0.028). Conclusion High LYMR, low NLR and high TIL–LYMR at baseline are predictive of pCR to nCRT for patients with rectal cancer. These parameters may help identify pCR patients and provide additional information for therapeutic decision-making.

Abstract
The aim of this study was to evaluate the evidence regarding the neutrophil-to-lymphocyte ratio (NLR) as a factor predictive of survival in bladder cancer patients. A search of PubMed and Embase for relevant studies between January 1, 1966 and November 10, 2016 was performed with the terms [NLR OR (neutrophil lymphocyte ratio)] AND [(bladder cancer) OR BCa OR NMIBC OR MIBC]. Inclusion required studies published in English containing bladder cancer patients and evaluating NLR as a predictive factor. Endpoints of NLR and survival data were extracted for pooled analysis. The pooled results showed that an elevated NLR was a predictor for poor overall survival (OS) [hazard ratio (HR) = 1.19, 95% confidence interval (CI) 1.07-1.31], cancer-specific survival (CSS) (HR = 1.40, 95% CI 1.17-1.69), recurrence-free survival (RFS) (HR = 1.58, 95% CI 1.24-2.03) and progression-free survival (PFS) (HR = 1.33, 95% CI 1.19-1.49) in patients with bladder cancer. Heterogeneity between studies was observed for OS, CSS and RFS, but not for PFS. Publication bias was detected for all these outcomes. Our results showed that elevated NLR might be valuable as a predictive factor of survival in bladder cancer patients.

Abstract
Aim: To determine the correlation of Helicobacter pylori infection with peripheral blood neutrophil/lymphocyte ratio (NLR) and mean platelet volume (MPV). Materials and methods: The NLR, MPV, platelets, leukocytes, neutrophils, and lymphocytes were calculated and the differences between groups were investigated. Results: A total of 199 patients were included in the study. Neutrophil/lymphocyte ratio was statistically lower in H. pylori-positive patients than in H. pylori-negative patients (1.94 ± 0.79 vs 2.67 ± 2.35 respectively, p = 0.04). There was no significant difference between H. pylori-negative patients and H. pylori-positive patients of severe intensity in terms of MPV. However, peripheral blood lymphocytes and platelets were statistically significantly higher in H. pylori-positive patients of severe intensity (lymphocytes 2150 ± 826 vs 2954 ± 2436 respectively, p = 0.000 and platelets 258247 ± 69494 vs 265611 ± 113397 respectively, p = 0.02) compared with H. pylori-negative patients. Conclusion: A moderate increase in the intensity of H. pylori does not lead to a significant change in MPV as measured by hemogram; however, it gives rise to a statistically significant fall in NLR. Presence of severe H. pylori-positive intensity leads to a statistically significant increase in peripheral blood lymphocytes and platelets compared with H. pylori-negative patients.

Abstract
BACKGROUND Disease activity of rheumatoid arthritis (RA) is evaluated by composite measures, such as Disease Activity Score (DAS). Recently, much attention has been paid to a neutrophil-lymphocyte (N/L) ratio to evaluate the prognosis and the efficacy of intervention in various diseases. To determine whether the N/L ratio is a prognostic marker or a surrogate marker of response to biologics, this study investigated the N/L ratio in RA patients treated with biological agents. METHODS The medical records were reviewed of 358 patients with RA in routine care who were treated with infliximab (144 patients), etanercept (120 patients), adalimumab (25 patients), tocilizumab (41 patients), or abatacept (28 patients). The 28-joint DAS (DAS28), a hemogram, erythrocyte sedimentation rate (ESR), and serum levels of C-reactive protein and matrix metalloproteinase 3 were assessed at baseline and 6 months after the treatment. RESULTS The average N/L ratio significantly decreased from 5.9 at baseline to 4.5 6 months after the treatment. The N/L ratio and the DAS28-ESR, both at baseline and 6 months after the treatment, were modestly but significantly correlated. The N/L ratio was greater in patients with high disease activity than in patients with low disease sactivity. The change of the N/L ratio (ΔN/L) and the change of the DAS28-ESR were modestly but significantly correlated. Regarding the therapeutic response, the N/L ratio at baseline showed no significant difference between the response criteria; however, the N/L ratio after 6 months of treatment and the ΔN/L ratio differed significantly. The ΔN/L was also significantly correlated with the change of the serum level of C-reactive protein and the change of the DAS28-ESR. CONCLUSION The N/L ratio is a marker of disease activity in RA. The ΔN/L ratio reflects the efficacy of biological agents but does not predict the response to biological agents.

Abstract
PURPOSE Chronic Helicobacter pylori gastritis affects two-thirds of the world's population and is one of the most common chronic inflammatory disorders of humans, the infection clearly results in chronic mucosal inflammation in the stomach and duodenum, which, in turn, might lead to abnormalities in gastroduodenal motility and sensitivity and is the most frequent cause of dyspepsia and peptic disease. Some studies showed that there was a correlation between low-grade inflammation as CRP and HP infection. The purpose of this study was to investigate the relationship between the presence of HP infection and platelet/lymphocyte ratio (PLR). METHOD A total of 200 patients who met the HP criteria and 180 age- and gender-matched control subjects were included in this randomized controlled trial. Patients were diagnosed to have HP according stomach biopsy and urea breath test, PLR was calculated from complete blood count at time of diagnosis and before initiating the treatment. RESULTS Patients with HP infection had significantly higher PLR compared to those without HP. Moreover, the patients with symptomatic HP had higher PLR than those with asymptomatic HP. While PLR increased as the severity of HP symptoms increased (r=.452, P<.001). CONCLUSION Our study indicated, for the first time, a significant association between HP infection and symptoms based on PLR, a simple and reliable indicator of inflammation. Furthermore, there an increase in PLR as the severity of HP increases.

Abstract
Purpose To evaluate the neutrophil to lymphocyte ratio (NLR) in patients with nonarteritic anterior ischemic optic neuropathy (NAION). Methods We investigated 112 subjects comprising 56 patients with NAION and 56 healthy controls at Süleyman Demirel University. Complete blood count, demographic, and clinic data from NAION patients were evaluated in this study. The NLR was calculated in all individuals and compared between the patient and control groups. Cut-off values were also determined. Then, the relationship between NLR and visual outcomes was investigated. Results The cut-off value for NLR was 1.64. NLR values were significantly higher in NAION patients than in healthy subjects (p < 0.001) and were directly correlated with erythrocyte sedimentation rate levels (r = 0.263, p = 0.006). Also, the NLR value was associated with visual outcomes. Receiver operator characteristic curve analysis revealed a 0.63 area under the curve (confidence interval, 53.7% to 74.1%), 85% sensitivity and 41% specificity at the cut-off NLR value. Conclusions The NLR may be a biomarker with good sensitivity that is quick, cost effective and easily detected in serum. It can be used in clinical practice to predict a NAION patient's prognosis in terms of visual outcomes.

Abstract
OBJECTIVE The neutrophil-to-lymphocyte ratio (NLR) has been used as a surrogate marker of systemic inflammation. We sought to investigate the association between NLR and wound healing in diabetic wounds. METHODS The outcomes of 120 diabetic foot ulcers in 101 patients referred from August 2011 to December 2014 were examined retrospectively. Demographic, patient-specific, and wound-specific variables as well as NLR at baseline visit were assessed. Outcomes were classified as ulcer healing, minor amputation, major amputation, and chronic ulcer. RESULTS The subjects' mean age was 59.4 ± 13.0 years, and 67 (66%) were male. Final outcome was complete healing in 24 ulcers (20%), minor amputation in 58 (48%) and major amputation in 16 (13%), and 22 chronic ulcers (18%) at the last follow-up (median follow-up time, 6.8 months). In multivariate analysis, higher NLR (odds ratio, 13.61; P = .01) was associated with higher odds of nonhealing. CONCLUSIONS NLR can predict odds of complete healing in diabetic foot ulcers independent of wound infection and other factors.

Abstract
BACKGROUND/AIMS Gastric intestinal metaplasia (IM) is an important risk factor for intestinal-type gastric carcinoma, and successful treatment critically depends on its timely detection. In order to guide appropriate endoscopic surveillance, objective knowledge on the anatomical predilection of intestinal metaplasia development is urgently needed. MATERIALS AND METHODS A total of 78,335 cases who underwent gastroduodenoscopy from 2008 to 2013 in Jiangsu and Anhui provinces in China, were studied. Demographic and clinical characteristics, as well as biopsy location and histological results, were analyzed. RESULTS This study revealed that intestinal metaplasia incidence was 28.5% in angulus, 20.24% in lesser curvature of the antrum, and 25.48% in corpus; and all these were significantly higher than those observed in other sites (P < 0.01). Histological grading of intestinal metaplasia in the lesser curvature of the antrum and angulus was generally worse than the grading observed in the greater curvature of the antrum. For Helicobacter pylori-positive patients, acute inflammation was more severe in the lesser curvature of the antrum compared with the greater curvature. In the H. Pylori-negative group, both acute and chronic inflammations were more severe in the lesser curvature of the antrum. CONCLUSIONS The angulus, lesser curvature in the antrum, and corpus are most prone to the development of intestinal metaplasia. Inflammation is most severe in the lesser curvature of the antrum, which corresponds to a higher predilection to develop intestinal metaplasia at this site. The lesser curvature of the antrum and corpus require the most attention during endoscopic biopsy surveillance.

Abstract
OBJECTIVE The aim of this study was to determine whether the neutrophil-to-lymphocyte ratio (NLR) can be used as a predictor for deep neck space infections (DNSIs) that occur as a complication of acute bacterial tonsillitis in the pediatric population. MATERIALS AND METHODS We evaluated the NLR values of 180 pediatric patients diagnosed with acute bacterial tonsillitis with or without DNSI who presented to the Otolaryngology Department of Marmara University Hospital between 2010 and 2013. In cases in which DNSI was suspected, the patients underwent complete otolaryngological examination and radiological imaging including CT and MRI. NLR was calculated in all the subjects and was compared between the patients with acute bacterial tonsillitis without DNSI and those with DNSI. RESULTS With regard to the tonsillitis-related complications, 17 patients had peritonsillar abscess (9.4%); five, parapharyngeal abscess (2.8%); and two, retropharyngeal abscess (1.1%). The mean NLR was significantly higher in the patients of acute bacterial tonsillitis with DNSI (P<0.05). The optimum cut-off value of NLR was determined to be 5.4. CONCLUSION This study is the first to investigate the relationship between NLR and DNSI as a complication of acute bacterial tonsillitis. The results demonstrated that the NLR value could be a potential laboratory parameter for diagnosing DNSIs.

Abstract
During the period reviewed, prevalence studies were essentially performed in less economically advanced countries and a high prevalence was found. The traditional risk factors for Helicobacter pylori positivity were mostly found. Transmission studied by molecular typing showed a familial transmission. The eventual role of water transmission was explored in several studies with controversial results. Concerning diagnosis, most of the invasive and noninvasive methods used for the diagnosis of H. pylori infection are long standing with efficient performance. The most interesting recent improvements in H. pylori diagnosis include advances in endoscopy, developments in molecular methods, and the introduction of omics-based techniques. Interpretation of old or newer method should take into account the pretest probability and the prevalence of H. pylori in the population under investigation.

Abstract
AIM It is widely known that inflammation is related to type 2 diabetes (T2D), but few studies have shown a direct relationship between the immune system and T2D using a reliable biomarker. Neutrophil:lymphocyte ratio (NLR) is an easy-to-analyze inflammation biomarker, but few studies have assessed the relationship between NLR and T2D. In order to evaluate how NLR is related to T2D, we designed a large-scale cross-sectional and prospective cohort study in an adult population. SUBJECTS AND METHODS Participants were recruited from the Tianjin Medical University General Hospital-Health Management Centre. Both a baseline cross-sectional (n=87,686) and a prospective (n=38,074) assessment were performed. Participants without a history of T2D were followed up for ∼ 6 years (with a median follow-up of 2.7 years). Adjusted logistic and Cox proportional hazards regression models were used to assess relationships between the quintiles of NLR and T2D (covariates: age, sex, BMI, smoking status, drinking status, hypertension, hyperlipidemia, and family history of cardiovascular disease, hypertension, hyperlipidemia, or diabetes). RESULTS The prevalence and incidence of T2D were 4.9% and 6.8/1000 person-years respectively. The adjusted odds ratio and hazard ratio (95% CI) of the highest NLR quintile were 1.34 (1.21, 1.49) and 1.39 (1.09, 1.78) (both P for trend <0.01) respectively as compared to the lowest quintile of NLR. Leukocyte, neutrophil, and lymphocyte counts do not significantly predict the eventual development of T2D. CONCLUSION The present study demonstrates that NLR is related to the prevalence and incidence of T2D, and it suggests that NLR may be an efficient and accurate prognostic biomarker for T2D.

Abstract
PURPOSE Neutrophil-to-lymphocyte ratio (NLR) is a new potential predictor of systemic inflammation in several diseases. In this study, we aimed to evaluate NLR in patients with keratoconus. METHODS This cross-sectional observational study included 54 patients with keratoconus and 25 age- and sex-matched control subjects. All participants underwent a detailed ophthalmological examination and corneal topography. The patients were divided into progressive and nonprogressive keratoconus groups on the basis of topographic parameters. Serum samples were obtained from all subjects, and the NLR was calculated. RESULTS The NLR was 3.27 ± 1.37 in the progressive keratoconus group versus 1.87 ± 0.39 and 1.87 ± 0.52 in the nonprogressive and control groups, respectively (P < 0.01). There was a positive correlation between NLR and progression (P < 0.05). In the receiver-operating characteristic analysis, an NLR ≥ 2.24 predicted the presence of progression with 79% sensitivity and 81% specificity. CONCLUSIONS The NLR is a simple and inexpensive marker of systemic inflammation. The NLR was found to be higher in patients with progressive keratoconus than in the nonprogressive group and controls.

Abstract
BACKGROUND Although a high neutrophil-to-lymphocyte ratio (NLR) has been reported to be a predictor of poor survival in patients with pancreatic cancers, its prognostic role in patients with advanced pancreatic cancer undergoing chemotherapy remains unclear. This study was performed to determine the prognostic role of NLR in patients with advanced pancreatic cancer undergoing chemotherapy. METHODS We retrospectively enrolled 403 patients undergoing chemotherapy for advanced pancreatic adenocarcinoma from 2002 to 2013. Univariate and multivariate analyses were performed to identify clinicopathological predictors of overall survival including baseline NLR (NLR before chemotherapy) and postchemotherapy NLR change (NLR change before and after one cycle of chemotherapy), using the Cox proportional hazards model. Clinicopathological characteristics related to baseline NLR and postchemotherapy NLR change were evaluated. RESULTS Univariate and multivariate analyses showed that both baseline NLR (NLR ≥ 3.1 vs. NLR < 3.1, hazard ratio [HR] = 1.42; P = 0.001) and postchemotherapy NLR change (NLR ≥ 3.1 and increased vs. NLR < 3.1 and decreased, HR = 2.39; P = 0.000) were independent prognostic factors in overall survival. NLR ≥ 3.1 before chemotherapy and NLR postchemotherapy change were significantly correlated with distant metastasis, serum CA19-9 levels, and serum albumin levels. CONCLUSIONS Baseline NLR and postchemotherapy NLR change may serve as potential biomarkers for overall survival in patients with advanced pancreatic cancer undergoing chemotherapy.
