[PMID: 38817657 PMCID: PMC11135416 DOI: 10.3748/wjg.v30.i19.2538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 03/07/2024] [Accepted: 04/23/2024] [Indexed: 05/20/2024] Open
Abstract
BACKGROUND Increased lipase level is a serological hallmark of the diagnosis of acute pancreatitis (AP) but can be detected in various other diseases associated with lipase leakage due to inflammation of organs surrounding the pancreas or reduced renal clearance and/or hepatic metabolism. This non-pancreatic hyperlipasemia (NPHL) is puzzling for attending physicians during the diagnostic procedure for AP. It would be clinically beneficial to identify the clinical and laboratory variables that hinder the accuracy of lipase diagnosis with the aim of improve it. A more precise description of the NPHL condition could potentially provide prognostic factors for adverse outcomes which is currently lacking. AIM To perform a detailed clinical and laboratory characterization of NPHL in a large prospective patient cohort with an assessment of parameters determining disease outcomes. METHODS A Hungarian patient cohort with serum lipase levels at least three times higher than the upper limit of normal (ULN) was prospectively evaluated over 31 months. Patients were identified using daily electronic laboratory reports developed to support an ongoing observational, multicenter, prospective cohort study called the EASY trial (ISRCTN10525246) to establish a simple, easy, and accurate clinical scoring system for early prognostication of AP. Diagnosis of NPHL was established based on ≥ 3 × ULN serum lipase level in the absence of abdominal pain or abdominal imaging results characteristic of pancreatitis. RESULTS A total of 808 patients [male, n = 420 (52%); median age (IQR): 65 (51-75) years] were diagnosed with ≥ 3 × ULN serum lipase levels. A total of 392 patients had AP, whereas 401 had NPHL with more than 20 different etiologies. Sepsis and acute kidney injury (AKI) were the most prevalent etiologies of NPHL (27.7% and 33.2%, respectively). The best discriminative cut-off value for lipase was ≥ 666 U/L (sensitivity, 71.4%; specificity, 88.8%). The presence of AKI or sepsis negatively affected the diagnostic performance of lipase. NPHL was associated with a higher in-hospital mortality than AP (22.4% vs 5.1%, P < 0.001). In multivariate binary logistic regression, not lipase but increased amylase level (> 244 U/L) and neutrophil-to-lymphocyte ratio (NLR) (> 10.37, OR: 3.71, 95%CI: 2.006-6.863, P < 0.001), decreased albumin level, age, and presence of sepsis were independent risk factors for in-hospital mortality in NPHL. CONCLUSION NPHL is a common cause of lipase elevation and is associated with high mortality rates. Increased NLR value was associated with the highest mortality risk. The presence of sepsis/AKI significantly deteriorates the serological differentiation of AP from NPHL.

Abstract
Mitigating sepsis-induced severe organ dysfunction with magnetic nanoparticles has shown remarkable advances in extracorporeal blood treatment. Nevertheless, treating large septic animals remains challenging due to insufficient magnetic separation at rapid blood flow rates (>6 L h-1) and limited incubation time in an extracorporeal circuit. Herein, superparamagnetic nanoclusters (SPNCs) coated with red blood cell (RBC) membranes are developed, which promptly capture and magnetically separate a wide range of pathogens at high blood flow rates in a swine sepsis model. The SPNCs exhibited an ultranarrow size distribution of clustered iron oxide nanocrystals and exceptionally high saturation magnetization (≈ 90 emu g-1) close to that of bulk magnetite. It is also revealed that CD47 on the RBCs allows the RBC-SPNCs to remain at a consistent concentration in the blood by evading innate immunity. The uniform size distribution of the RBC-SPNCs greatly enhances their effectiveness in eradicating various pathogenic materials in extracorporeal blood. The use of RBC-SPNCs for extracorporeal treatment of swine infected with multidrug-resistant E. coli is validated and found that severe bacteremic sepsis-induced organ dysfunction is significantly mitigated after 12 h. The findings highlight the potential application of RBC-SPNCs for extracorporeal therapy of severe sepsis in large animal models and potentially humans.

Abstract
We aimed to evaluate the association between inflammation-based prognostic markers and mortality after hip replacement. From March 2010 to June 2020, we identified 5,369 consecutive adult patients undergoing hip replacement with C-reactive protein (CRP), albumin, and complete blood count measured within six months before surgery. Receiver operating characteristic (ROC) curves were generated to evaluate predictabilities and estimate thresholds of CRP-to-albumin ratio (CAR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR). Patients were divided according to threshold, and mortality risk was compared. The primary outcome was one-year mortality, and overall mortality was also analyzed. One-year mortality was 2.9%. Receiver operating characteristics analysis revealed areas under the curve of 0.838, 0.832, 0.701, and 0.732 for CAR, NLR, PLR, and modified Glasgow Prognostic Score, respectively. The estimated thresholds were 2.10, 3.16, and 11.77 for CAR, NLR, and PLR, respectively. According to the estimated threshold, high CAR and NLR were associated with higher one-year mortality after adjustment (1.0% vs. 11.7%; HR = 2.16; 95% CI 1.32-3.52; p = 0.002 for CAR and 0.8% vs. 9.6%; HR = 2.05; 95% CI 1.24-3.39; p = 0.01 for NLR), but PLR did not show a significant mortality increase (1.4% vs. 7.4%; HR = 1.12; 95% CI 0.77-1.63; p = 0.57). Our study demonstrated associations of preoperative levels of CAR and NLR with postoperative mortality in patients undergoing hip replacement. Our findings may be helpful in predicting mortality in patients undergoing hip replacement.

Abstract
Several mechanisms, including altered local and systemic immune system, apoptosis, and new angiogenesis, are responsible for the development and progression of endometriosis. Over the years many markers have been studied, like CA 125 and, recently, neutrophil-to-lymphocyte ratio (NLR). This tool is cost-effectiveness and non-invasiveness as a marker of systemic inflammatory diseases. The aim of this study is to assess the role of NLR in the real-life management of patients with endometriosis in order to evaluate the possible association between this value and symptoms. We performed a retrospective analysis of 199 premenopausal women affected by endometriosis, from January 2013 to December 2020, evaluating the characteristics of disease, the symptoms and the NLR. Analyzing the neutrophiles, the mean ± SD value was 6.1 ± 4.5 × 103/ul, while for lymphocytes mean ± SD value was 1.8 ± 0.7.NLR was categorized according to its median value (> 2.62 vs ≤ 2.62). The comparison between NLR values and CA 125, endometriosis stage, dysmenorrhea and presence of chronic pelvic pain, adjusting for previous therapy did not find a significant association. An interesting result, although not significant, was the association between NLR and chronic pelvic pain (OR = 1.9). In the sub-group of patients without previous therapy this association is even stronger (OR = 4.8, 95% CI 0.5-50.2, p = 0.190). The link between NLR and chronic pelvic pain can provide a further hint to the clinician even when taking symptoms into account to develop a particular therapeutic treatment related to the various expressions of NLR. Finally, NLR may enable the creation of customized follow-up protocols that divide patients into high- and low-risk categories for endometriosis recurrence.

Abstract
The role of the inflammatory process in the pathogenesis of local edema-related envenomation has not been explored with endemic venomous snakebites in Korea. Gloydius species are responsible for most snakebites in South Korea. In this study we aimed to investigate whether the neutrophil-lymphocyte ratio is relevant to snake envenomation-induced local edema in South Korea. This retrospective study divided 126 patients into two groups according to local edema severity at presentation. Logistic regression models were used to investigate the association between the neutrophil-lymphocyte ratio and local edema. Sixty-one (48.4%) patients had grade 2 or higher local edema at presentation despite 21 of them being given antivenom before presentation. During hospitalization, local edema progressed in 61 patients 48 (11.5-48) hours after presentation, and 54 patients demonstrated grade 3 or higher local edema. A higher neutrophil-lymphocyte ratio at presentation after adjustment for factors related to envenomation and antivenom administration and factors influencing the neutrophil-lymphocyte ratio were associated with both a higher grade of local edema at presentation and a higher peak local edema grade during hospitalization. The delta neutrophil-lymphocyte ratio during the first 24 h after presentation was related to the local edema progression after presentation. The neutrophil-lymphocyte ratio at presentation is associated with the severity of local edema-related envenomation. Furthermore, the change in the neutrophil-lymphocyte ratio during the first 24 h is related to the risk of local edema progression. Further clinical and experimental research aimed at investigating the role of inflammation on the pathogenesis of local edema should be conducted. This study may suggest the introduction of short-term anti-inflammatory agents considering the failure of antivenom to curb local edema.

Abstract
INTRODUCTION The Neutrophil-Lymphocyte Ratio (NLR) in blood has demonstrated its capability to predict bacteremia in emergency departments, and its association with mortality has been established in patients with sepsis in intensive care units. However, its potential concerning mortality and readmission in patients with Gram-negative bacteremia (GNB) is unexplored. METHODS This retrospective cohort study included patients with GNB between 2018 and 2022 from six hospitals in the Capital Region of Denmark. Patients who were immunosuppressed or had missing NLR values on the day of blood culture were excluded. Logistic regression models were used to analyze the association between NLR levels and 90-day all-cause mortality, while the logit link interpretation of the cumulative incidence function was used to assess the association between NLR levels and 60-day readmission. Associations were quantified as odds ratios (OR) with corresponding 95% confidence intervals (CI). RESULTS The study included 1763 patients with a median age was 76.8 years and 51.3% were female. The median NLR was 17.3 and 15.8% of patients had a quick sequential organ failure assessment score of two or three. Urinary tract infection (UTI) was the most frequent focus and Escherichia coli the most frequent pathogen. Statistically significant differences in median NLR were found by age group and pathogen, and for patients with or without hypertension, liver disease, chronic obstructive pulmonary disease, dementia, and alcohol abuse. 378 patients (21.4%) died before 90 days. 526 (29.8%) patients were readmitted to the hospital within 60 days. For each doubling of the NLR, the OR for all-cause 90-day mortality was 1.15 (95% CI, 1.04-1.27) and 1.12 (95% CI, 1.02-1.24) for 60-day readmission. Analysis of subgroups did not show statistically significant differences between groups in relation to the association between NLR and mortality. The discriminatory ability of NLR for mortality was limited and comparable to blood neutrophil or lymphocyte count, producing receiver operating characteristic curves with an area under the curve of 0.59 (95% CI, 0.56-0.63), 0.60 (95% CI, 0.56-0.65) and 0.53 (95% CI, 0.49-0.56), respectively. CONCLUSION Blood neutrophil-lymphocyte ratio was associated with 90-day all-cause mortality and 60-day readmission in patients with GNB. However, the ratio has limited ability in predicting mortality or readmission.

Abstract
Background We conducted a systematic review and meta-analysis, based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, to evaluate current literature on diagnostic value of neutrophil to lymphocyte ratio (NLR) in discrimination between tuberculosis (TB) and bacterial community acquired pneumonia (B-CAP). Methods Literature search was conducted from July 20, 2023 using Scopus, PubMed, and Web of Science databases. STATA software (version 12.0; Stata Corporation) was used for all analyses. Results We found that patients with TB had significantly lower levels of NLR compared to those with B-CAP (SMD = -1.09, 95 %CI = -1.78- -0.40, P = 0.002). In the quality subgroup analysis, we found that patients with TB had significantly lower level of NLR compared to those with B-CAP consistent in moderate (SMD = -0.86, 95 %CI = -2.30, 0.57, P = 0.23) and high-quality studies (SMD = -1.25, 95 %CI = -2.07, -0.42). In the subgroup analysis based on continent, we found that patients with TB had significantly lower level of NLR compared to those with B-CAP in studies performed in Asian populations (SMD = -1.37, 95 %CI = -2.13, -0.61, P < 0.001), but not on African population (SMD = -0.02, 95 %CI = -1.06, 1.02, P = 0.97). The result of this study did not change after execution of sensitivity analysis. The pooled sensitivity of NLR was 0.86 (95% CI = 0.80, 0.91), and the pooled specificity was0.88 (95% CI = 0.69, 0.95). Conclusion Patients with TB had a significantly lower NLR levels compared to those with B-CAP, so we utilized this biomarker for distinguishing between the disorders.

Abstract
Liver cirrhosis patients are highly susceptible to infections, affecting survival, but current parameters for detecting infection are not reliable enough in this population. We investigated the ability of white blood cell (WBC), ∆WBC, neutrophil and ∆neutrophil counts, neutrophil-to-lymphocyte (NLR) and ∆NLR ratios and C-reactive protein (CRP) and procalcitonin (PCT) levels to identify infection and predict short-term mortality in liver cirrhosis patients. We recruited 233 patients with liver cirrhosis hospitalized with acute decompensation (AD) who had an outpatient visit within 1 month (baseline laboratory data) and followed them for 90 days. Difference between laboratory values at baseline and the AD episode was defined as delta (∆) values of the parameters. Delta values did not increase the diagnostic and predictive ability of investigated parameters. The CRP level was found to be the best diagnostic marker for infection in patients with cirrhosis. However, NLR seems to be superior for short-term mortality prediction, better than the WBC count. Distinguishing inflammations of different origin is a remaining clinical challenge in acutely decompensated cirrhosis. Based on our results, NLR might be more suitable for predicting short-term mortality in patients with AD than the WBC count currently included in the CLIF-C AD score.

Abstract
INTRODUCTION Plasmapheresis is a frequently used procedure that removes the pathogenic components from circulation. We aimed to evaluate the relationship between plasmapheresis, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and mortality in the intensive care unit (ICU) between 2014 and 2021. METHODS Forty-nine patients (27 females and 22 males) were included. Demographic characteristics, laboratory values of the day of admittance to the ICU, APACHE II scores, and length of stay were recorded. RESULTS The mean age was 52.73 ± 16.93. APACHE II value (p = 0.003; p < 0.01), NLR ratio (p = 0.001; p < 0.01) and PLR ratio (p = 0.001; p < 0.01) of the surviving group were lower than those of the deceased group, which was statistically significant. CONCLUSION As high PLR and NLR levels suggest increased mortality in the ICU population, attention should be paid for increased NLR and PLR when plasmapheresis is decided on in the ICU.

The evaluation of SIRS status with hemato-biochemical indices in bitches affected from pyometra and the Usefulness of these indices as a potential diagnostic tool. Theriogenology 2022; 193:120-127. [PMID: 36156424 DOI: 10.1016/j.theriogenology.2022.09.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 09/09/2022] [Accepted: 09/09/2022] [Indexed: 11/22/2022]
Abstract
The aims of this study were to establish a cut-off point by evaluating the usability of the hemato-biochemical indices to determine the severity of inflammation caused by pyometra, and to determine the practical usage of the indices as a diagnostic biomarker in cases of pyometra. Animals that were admitted to Ankara University Veterinary Faculty Obstetrics and Gynecology Clinic were included in the present study. Dogs suffering from pyometra were allocated to two groups according to their SIRS status (SIRS, n = 12; Non-SIRS (NSIRS, n = 16)). Healthy dogs presented for routine ovariohysterectomy were used as the control (n = 13). Blood samples were collected into two tubes containing EDTA for hematological analysis and without anticoagulant for biochemical tests before the beginning of treatment. Hemato-biochemical indices, which are Neutrophil-Lymphocyte Ratio (NLR), Monocyte-Lymphocyte Ratio (MLR), Neutrophil Percentage-Albumin Ratio (NPAR), Platelet-Lymphocyte Ratio and Systemic Immune-Inflammation Index, were calculated. All data were analyzed using the MIXED procedure of the SPSS. Receiver operating characteristics curves were used to determine the dog level threshold for evaluating the SIRS status and used to determine a predicted threshold with hemato-biochemical indices for differentiation between dogs with pyometra (regardless of SIRS status) and the control. Pairwise comparisons were carried out of the area under the curve (AUC) for thresholds of SII, NLR, PLR, MLR, NPAR. White blood cells, lymphocytes, monocyte, neutrophil, ALP, NLR, MLR, and NPAR levels were greater in dogs that suffer from SIRS (P < 0.05). Red blood cells and hematocrit levels were significantly higher in the control group (P < 0.05). Albumin levels were higher in the control group (P < 0.05). Moreover, NLR, MLR and NPAR levels were found to be significantly higher in the SIRS group (P < 0.05). Besides, NLR and MLR were the best predictors for diagnosis of the SIRS with the AUC values of 0.936, and 0.966 respectively. Furthermore, NLR, MLR and SII could be a useful diagnostic tool for pyometra with the AUC values of 0.955, 0.931, 0.716. The blood indices could be used as fast, easily accessible, and inexpensive markers for the evaluation of the SIRS status in dogs with pyometra together with diagnosis.

Abstract
Giriş: B12 vitamin eksikliğinin; kan tetkiklerine, ortalama trombosit hacmine (MPV) ve inflamasyon markerlarından nötrofil-lenfosit oranına (NLR) etkilerinin araştırılması amaçlanmıştır.Yöntem: Çalışmamız 375 hasta üzerinde yapılmıştır. B12’si düşük (<130 pg/dL) saptanan 170 hasta deney grubu olarak, B12 düzeyleri normal olan 205 kişide kontrol grubu olarak kabul edilmiştir. Bu iki grup arasında beyaz kan hücreleri (WBC), trombosit sayısı (Plt), hemoglobin (Hgb), ortalama eritrosit hacmi (MCV), MPV, nötrofil, lenfosit sayıları ve nötrofil-lenfosit oranları (NLR) incelenmiştir.Bulgular: Yaş ortalaması B12 eksik grupta 48.45 ±17.497 yıl, kontrol grubunda ise 51.93 ±16.175 yıl idi. Eksik grupta B12vitamini ortalaması 101,41 ± 20,50 pg/mL (min-max; 37-130), kontrol grubunda ise 257,24 ± 88,13 pg/mL (min-max; 131-498) idi. WBC, Hgb, Plt, nötrofil, lenfosit, MVC, MPV ve NLR arasında istatiksel açıdan anlamlı bir fark olmadığı gözlendi.Sonuç: Çalışmamızda B12 eksikliği ile kan tetkikleri arasında anlamlı bir ilişki bulamadık. Önceki çalışmalarda B12 eksikliğinde MPV değerlerinin etkilendiğine dair bilgiler bulunmaktadır. Yaptığımız çalışmada da B12 eksikliği ile MPV ve NLR arasında anlamlı bir ilişkinin olmadığını saptadık (p>0,05). B12 eksikliğinin derecesi ve süresi uzadıkça nasıl değişiklikler meydana geleceği ve özellikle de aterojenik olaylara etkisi hakkında yapılacak yeni çalışmalara ihtiyaç vardır.

Abstract
Acetylsalicylic acid (ASA) is one of the most commonly used drugs in the world. It derives from the extract of white willow bark, whose therapeutic potential was known in Egypt since 1534 BC. ASA’s pharmacological effects are historically considered secondary to its anti-inflammatory, platelet-inhibiting properties; however, human studies demonstrating a pro-inflammatory effect of ASA exist. It is likely that we are aware of only part of ASA’s mechanisms of action; moreover, the clinical effect is largely dependent on dosages. During the past few decades, evidence of the anti-infective properties of ASA has emerged. We performed a review of such research in order to provide a comprehensive overview of ASA and viral, bacterial, fungal and parasitic infections, as well as ASA’s antibiofilm properties.

Abstract
The scarcity of deceased donor livers has led to allocation of grafts to only the most seriously ill patients with a high Model for End-Stage Liver Disease (MELD) score, which has resulted in a high mortality rate after deceased donor liver transplantation (DDLT). The aim of this study is to identify risk factors for posttransplant mortality and thereby reduce futile outcomes in DDLT. Between 2013 and 2019, 57 recipients with MELD scores ≥30 underwent DDLT in our center. We retrieved data and identified the risk factors for 90-day posttransplant mortality. The perioperative clinical and laboratory parameters of patients who did or did not survive for 90 days were subjected to logistic regression analysis. Twelve patients died within 90 days. Results of univariate analysis indicated that the differences in patient survival were determined by the amount of intraoperative platelets transfused, the presence of posttransplant septicemia, and systemic immune-inflammation index (SII) at the time of listing with MELD scores ≥30. Multivariate analysis revealed that an SII ≥870 (× 109/L) and posttransplant septicemia were independent risk factors for 90-day mortality. Twenty-two patients had SIIs ≥870, and 13 of these patients had posttransplant septicemia. Of the 13 patients, 90-day mortality occurred in 10 cases. However, in 35 patients with SIIs <870, 90-day mortality due to posttransplant septicemia was recorded only in 1 patient. In conclusion, a preoperative SII ≥870 in a patient with a high MELD score may be a significant risk factor for early posttransplant mortality. Because posttransplant septicemia in patients with high SIIs can lead to fatality, a more intensive effort to prevent infection is needed for patients undergoing DDLT carrying such risk factors to avoid futile liver transplantation.

Inflammatory biomarkers to predict postoperative infectious complications after cytoreductive surgery and HIPEC for peritoneal carcinomatosis. Eur J Surg Oncol 2021; 48:455-461. [PMID: 34565632 DOI: 10.1016/j.ejso.2021.09.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 08/30/2021] [Accepted: 09/16/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Early detection of postoperative infectious complications (IC) is crucial after Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). The aim of this study was to evaluate the predictive role of early postoperative inflammatory biomarkers level for the detection of postoperative IC. METHODS a retrospective study was performed including 199 patients treated with complete CRS/HIPEC for PC from various primary origins from September 2012 to January 2021. Patients were monitored by a routine measurement of inflammatory biomarkers (CRP, leukocytes, neutrophils, lymphocytes, neutrophile-to-lymphocyte ratio and platelets-to-lymphocyte ratio). Inflammatory biomarkers were compared between patients with vs without IC. RESULTS IC occurred for 68 patients (34.2%). CRP values were significantly higher in patients with IC on POD 3, 5 and 7 (CRP = 166 mg/L [128-244], 155 mg/L [102-222] and 207 mg/L [135-259], respectively). The CRP on POD7, with a cut-off value of 100 mg/L, was an excellent predictor of postoperative IC (AUC = 90.1%). The CRP on POD 5, with a cut-off value of 90 mg/L, was a good predictor of postoperative IC (AUC = 83.2%). NLR values were significantly higher in patients with IC on POD 3, 5 and 7. NLR on POD 5 and 7 higher than 9.7 and 6.3, respectively, were fair predictors (AUC = 70.8 and 79.6, respectively). CONCLUSION CRP levels between POD3 and 7 are the best predictors of postoperative IC after CRS/HIPEC. The presence of postoperative IC should be suspected in patients with CRP higher than 140 mg/L, 90 mg/L or 100 mg/L on PODs 3, 5 or 7.

Abstract
BACKGROUND Gutmicrobiota dysbiosis, endotoxemia, and systemic inflammation are major factors contributing to disease pathophysiology in patients with critical illness. The present study aimed to assess the effects of synbiotic supplementation on serum endotoxin and inflammationof adult patients with critical illness. METHODS This double-anonymized, randomized controlled trial was conducted at the intensive care unit (ICU) of Imam Reza Hospital in Mashhad, Iran. In the intervention group, 20 patients received synbiotic capsules (containing a combination of Lactobacillus, Bifidobacterium, Streptococcus, and fructooligosaccharides) twice per day for a maximum of 14 days. In the control group, 18 patients received placebo capsules. The serum levels of endotoxin and C-reactive protein and the neutrophil to lymphocyte ratio (NLR) were measured before and after the intervention. In addition, clinical outcomes and Acute Physiology and Chronic Health Evaluation and Sequential Organ Failure Assessment scores were recorded. RESULTS Basic characteristics were similar in the intervention and control groups. The NLR and serum endotoxin levels (median [IQR]) significantly declined in the synbiotic group (7.83 [4.58-12.57] to 6.01 [4.25-9.38]; P = .04; and 11.98 [10.64-12.65] to 10.58 [9.41-12.34]; P = .03, respectively). However, no significant changes were observed in the mentioned parameters in the placebo group. The clinical outcomes were also similar in the study groups, such as the length of hospital/ICU stay and hospital/28-day mortality rate. CONCLUSION Although synbiotic supplementation (500 mg twice daily for 14 days) could reduce serum endotoxin and inflammatory markers, it had no effects on the clinical outcomes of the patients.

Abstract
Cutaneous leishmaniasis (CL) is a vector-borne parasitic disease characterized by various skin lesions that can cause deformities when healed. Our aim in this study is to show the utility of parameters such as neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), and mean thrombocyte volume (MTV) as auxiliary laboratory methods in CL patients. About 107 patients who were admitted to our dermatological and venereal diseases outpatient clinic between January 2018 and January 2019 and were diagnosed with CL by microscopic examination and 74 healthy individuals were included in the study. There were no significant differences between the patient and control group in terms of neutrophil counts, leukocyte counts, platelet counts, and NLR values (P values: .271, .053, .263, and .459, respectively). When the TLR and MTV values of patients with CL and those of the healthy controls were compared, it was found that TLR and MTV values were statistically higher in patients with CL (P values of .010 and .044, respectively). Based on these data, NLR was not considered to be a suitable parameter for demonstrating inflammation in CL patients, but TLR and MTV were held to be an appropriate parameter for demonstrating inflammation in CL patients. In addition, we think that the increase in MTV and TLR, can be used as an auxiliary laboratory test in the diagnosis of CL disease.

Abstract
Background Although the neutrophil percentage-to-albumin ratio (NPAR) has proven to be a robust systemic inflammation-based predictor of mortality in a wide range of diseases, the prognostic value of the NPAR in critically ill patients with cardiogenic shock (CS) remains unknown. This study aimed at investigating the association between the admission NPAR and clinical outcomes in CS patients using real-world data. Methods Critically ill patients diagnosed with CS in the Medical Information Mart for Intensive Care-III (MIMIC-III) database were included in our study. The study endpoints included all-cause in-hospital, 30-day, and 365-day mortality in CS patients. First, the NPAR was analyzed as a continuous variable using restricted cubic spline Cox regression models. Second, X-tile analysis was used to calculate the optimal cut-off values for the NPAR and divide the cohort into three NPAR groups. Moreover, multivariable Cox regression analyses were used to assess the association of the NPAR groups with mortality. Results A total of 891 patients hospitalized with CS were enrolled in this study. A nonlinear relationship between the NPAR and in-hospital and 30-day mortality was observed (all P values for nonlinear trend<0.001). According to the optimal cut-off values by X-tile, NPARs were divided into three groups: group I (NPAR < 25.3), group II (25.3 ≤ NPAR < 34.8), and group III (34.8 ≤ NPAR). Multivariable Cox analysis showed that higher NPAR was independently associated with increased risk of in-hospital mortality (group III vs. group I: hazard ratio [HR] 2.60, 95% confidence interval [CI] 1.72-3.92, P < 0.001), 30-day mortality (group III vs. group I: HR 2.42, 95% CI 1.65-3.54, P < 0.001), and 365-day mortality (group III vs. group I: HR 6.80, 95% CI 4.10-11.26, P < 0.001) in patients with CS. Conclusions Admission NPAR was independently associated with in-hospital, 30-day, and 365-day mortality in critically ill patients with CS.

Abstract
The geriatric nutritional risk index (GNRI) is associated with the prognosis of many diseases. However, the association between the GNRI and the prognosis of patients aged ≥65 years with severe community-acquired pneumonia (SCAP) has not been studied. We aimed to evaluate the prognostic value of GNRI in elderly SCAP patients.This study retrospectively analyzed the clinical data of 346 patients aged ≥65 years with SCAP from December 2013 to September 2019. Patients were divided into 4 groups by the GNRI. The chi-square test or student's t test was used to compare the differences between the groups. Logistic regression analysis was used to evaluate the factors that affect prognosis. The receiver operating characteristic curve was used to compare the prognostic performance of the GNRI with other indicators. A GNRI-based nomogram was established based on the result of the multivariate analysis.Two hundred nine (60.4%) patients had a poor prognosis. GNRI scores were significantly lower in the poor prognosis group than in the group with a good prognosis. In the multivariate analysis, gender, mean arterial pressure, neutrophil counts, and the GNRI were independently correlated with the prognosis of elderly patients. The GNRI was a significantly better predictor for poor prognosis than other indicators. The GNRI-based nomogram had excellent prediction capabilities.GNRI is a simple and effective prognostic indicator for elderly patients with SCAP, and a GNRI-based nomogram can aid in developing individualized treatment plans for elderly patients with SCAP.

Abstract
Inflammation is a key feature in the pathogenesis of sepsis and acute respiratory distress syndrome (ARDS). Sepsis and ARDS continue to be associated with high mortality. A key contributory factor is the rudimentary understanding of the early events in pulmonary and systemic inflammation in humans, which are difficult to study in clinical practice, as they precede the patient's presentation to medical services. Lipopolysaccharide (LPS), a constituent of the outer membrane of Gram-negative bacteria, is a trigger of inflammation and the dysregulated host response in sepsis. Human LPS models deliver a small quantity of LPS to healthy volunteers, triggering an inflammatory response and providing a window to study early inflammation in humans. This allows biological/mechanistic insights to be made and new therapeutic strategies to be tested in a controlled, reproducible environment from a defined point in time. We review the use of human LPS models, focussing on the underlying mechanistic insights that have been gained by studying the response to intravenous and pulmonary LPS challenge. We discuss variables that may influence the response to LPS before considering factors that should be considered when designing future human LPS studies.

Abstract
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) is a biomarker that is correlated with systemic inflammation and poor prognosis in solid tumors. We investigated the value of NLR in predicting survival in a large population of head and neck cancer patients in the United States. METHODS We performed a retrospective cohort study of Veterans Affairs patients with head and neck squamous cell carcinoma (HNSCC) diagnosed between January 2000 and December 2017. We compared 5-year overall survival and cancer-specific survival for different NLR tertiles using cox proportional hazards modeling with adjustment for covariates. RESULTS The primary cohort consisted of 14 644 subjects of which 99% were male. Relative to patients with NLRs in the lower tertile, patients with NLRs in the top tertile had an 71% increased hazard of all-cause mortality (P < .001) and 44% increased hazard of cancer-specific mortality (P < .001) at 5 years. CONCLUSIONS Elevated NLR in HNSCC confers a poor prognosis.

Abstract
Sepsis is a clinical syndrome characterized by the presence of circulating microbial endotoxins and oxidative stress. Endotoxin and oxidative stress activate endothelial cells via a convergent signaling pathway (TLR4/MyD88/PI3 K/PLCɣ/NF-B) that stimulates both the transcription of SELP gene (which encodes for human P-selectin) and the release of P-selectin from Weibel-Palade bodies (WPBs). However, time course pattern of P-selectin surface aggregation has not been established in endothelial cells under 24 h of endotoxic or oxidative stress. Our study shows that P-selectin has at least two waves of aggregation at the cell surface: one 10 min and the other 12 h after endotoxic or oxidative stress. The first wave depends exclusively on WPB delivery to the cell membrane, while the second depends on P-selectin translation machinery, ER-Golgi sorting, and WPB surface delivery. Understanding adhesion molecule dynamics in endothelial cells could provide further molecular insights to develop diagnostic or therapeutic tools to aid in the management of sepsis.

Abstract
BACKGROUND Differentiating pneumonia from chronic heart failure (HF) in normothermic subjects in the emergency department (ED) is significantly difficult. OBJECTIVE This study aimed to evaluate the predictive value of the neutrophil-to-lymphocyte ratio (NLR) in establishing the diagnosis of pneumonia in normothermic subjects with chronic HF in the ED. METHODS This study included 523 adult dyspneic patients with chronic HF presenting in the ED. We categorized the selected patients into the nonpneumonia group (NPG) and the pneumonia group (PG), and the patients' serum white blood cell (WBC), neutrophil, and lymphocyte counts, NLR, and C-reactive protein (CRP) levels were measured upon arrival in the ED. Subsequently, we compared their predictive powers after performing a propensity score-matching (PSM) analysis. RESULTS The PG included 120 (22.9%) patients. After performing PSM, the mean NLR was significantly higher in the PG than in the NPG group (p < 0.001). According to the receiver operating characteristic area under the curve (AUC) analysis of inflammatory markers, the AUC of the NLR was significantly higher than that of WBCs, neutrophils, lymphocytes, and CRP. CONCLUSION The predictive value of the NLR was significantly higher than that of WBCs, neutrophils, lymphocytes, and CRP. Therefore, NLR may be a useful adjunctive marker to establish the early diagnosis of pneumonia in normothermic patients with chronic HF in the ED.

Abstract
The aim of this study was to investigate the prognostic values of neutrophil-to-lymphocyte ratio and red blood cell distribution width in diabetic foot ulcers treatment. A total of 250 adult patients who were treated in our clinic between 2007 and 2018 for diabetic foot ulcers were evaluated retrospectively. Diabetic foot ulcers were divided into 4 groups: major amputation, minor amputation, chronic wound, and complete healing. The mean age of our study groups was 60 years (range = 55-65 years). The mean follow-up period was 28 ± 4.3 months. Neutrophil-to-lymphocyte ratio and red blood cell distribution width cutoff values were determined as 4.3 and 12.1, respectively, for patients in complete recovery group (C sig. = .995 and .871, respectively; P < .05). Neutrophil-to-lymphocyte ratio and red blood cell distribution width cutoff values for patients in the major amputation group were 6.73 and 13.4 (C sig. = .864 and .951, respectively; P < .05), respectively. According to the χ2 comparison of the groups, major amputation was seen in patients with neutrophil-to-lymphocyte ratio >6.3, and complete recovery was seen in patients with neutrophil-to-lymphocyte ratio <4.3. In patients with red blood cell distribution width >13.4, major amputation was found to be significant ( P < .05). According to these results, neutrophil-to-lymphocyte ratio and red blood cell distribution width are inexpensive and easy to access predictive parameters in the diagnosis and follow-up of diabetic foot ulcers.

Abstract
Aim/Background Early diagnosis of patients with colon cancer is one of the most important parameters affecting the survival of patients. In this study, we aimed to examine the effect of the age, hemoglobin (Hb), albumin, neutrophil lymphocyte ratio (NLR), thrombocyte lymphocyte ratio (PLR), and mean platelet values (MPV) on the separation of benign and malignant diseases in patients with suspected colon wall thickness (CWT) observed in abdominal computed tomography (CT) examination. Method The study included 116 patients between the ages of 18 and 95 who had CT examination where the colon wall could be evaluated and who also had colonoscopy. Patients suspected for CWT in CT with difficulties in differential diagnosis were divided into two groups according to colonoscopic-histopathological evaluations. Normal or benign pathological causes were included in the first group, while malignant causes constituted the second group. Whether the two groups differed in terms of CWT, Hb, age, albumin, NLR, PLR, and MPV values was investigated with descriptive statistics. Results One hundred and sixteen patients (74 males, 42 females) with CT examinations and colonoscopic sampling were included in the study. After colonoscopic and histopathological evaluations, there were 64 cases in the first group and 52 in the second group. According to the results of the univariate analysis and multivariate logistic regression, CWT, Hb, NLR, and MPV were identified to be independent variables for determining colon cancer. Conclusion A combined evaluation of Hb, NLR, and MPV values in patients with CWT in abdominal CT examination may contribute to the separation of benign and malignant pathologies.

Abstract
Purpose Red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), and platelet count (PLT) have been reported to be associated with the prognosis of malignancies; this study aimed to evaluate the prognostic significance of the inflammatory prognostic scoring index (IPSI), comprised of RDW, N LR, and PLT for overall survival (OS) in newly diagnosed multiple myeloma patients in the bortezomib-based chemotherapy era. Patients and methods The prognostic significance of variables associated with the OS of 175 newly diagnosed multiple myeloma patients was evaluated through univariate and multivariate analyses. The cut-off values of RDW, NLR, and PLT were obtained from references. Patients with high RDW (RDW>14) were given a score of 1; patients with high NLR (NLR>2) or low PLT (PLT≤150) were given a score of 2. According to the obtained scores, the inflammatory prognostic scoring index (IPSI) was formed, in which patients were grouped into high-risk group (4–5 points), intermediate-risk group (3 points) and low-risk group (0–2 points). Results OS varied significantly in different IPSI groups (P< 0.001). On multivariate analysis, the IPSI was an independent prognostic factor for OS (intermediate-risk group HR 2.89, 95% CI 1.60–5.22, high risk-group HR 14.50, 95% CI 7.26–28.93, P<0.001). Importantly, with IPSI as supplement to the International Staging System (ISS), a significant difference in OS was observed among IPSI subgroups (ISS I, P<0.001; ISS II, P=0.008; ISS III, P<0.001). Conclusion The IPSI, comprised of RDW, NLR, and PLT, played specific role in the prognosis of patients preliminarily diagnosed with multiple myeloma in the bortezomib-based chemotherapy era and could be a beneficial supplement for ISS staging.

Abstract
Systemic inflammatory response syndrome (SIRS) is the manifestation of the systemic response to an infectious or non-infectious disease. We evaluated the association between erythrocyte parameters, including nucleated red blood cells (NRBCs) and leukocyte ratios (NLR, neutrophil-to-lymphocyte ratio; BLR, band neutrophil-to-lymphocyte ratio; BLNR, band neutrophil-to-neutrophil-to-lymphocyte ratio). A review of the medical records was conducted searching SIRS dogs among those admitted to our intensive care unit and a SIRS grading was obtained based on how many criteria were fulfilled. The Acute Patient Physiology and Laboratory Evaluation (APPLEfast) score was assessed in each dog. Survival rate was assessed 15 days after admission. Dogs with clinical and/or clinicopathological signs of hemolytic or hemorrhagic disorders were excluded. Dogs with ≥2 criteria of SIRS along with a documented underlying infectious cause were recorded as septic (32/90, 35%). A SIRS grading >2 (p = .001) and an APPLEfast score > 25 (p = .03) were associated with mortality. Twenty-two of SIRS dogs (24%) showed circulating NRBCs. The occurrence of circulating NRBCs was associated with the mortality in SIRS groups (p = .0025). The median NLR was 11.69 and NLR was lower in septic dogs compared to non-septic ones (p = .0272). APPLEfast, SIRS grading and circulating NRBCs may be considered as negative prognostic factors in canine SIRS. NLR could be a useful tool in dogs with SIRS, which was significantly lower in the septic group. Further prospective, large-scale studies investigating BLR and BNLR in canine SIRS are warranted.

Abstract
Background Factors associated with left ventricular systolic dysfunction (LVSD) of peritoneal dialysis (PD) patients are limited. We aim to explore and quantify the associated factors of LVSD among PD patients. Methods Participants from a PD clinic treated between 2012 and 2014 at the HRH Princess Maha Chakri Sirindhorn Medical Center, Srinakharinwirot University, Nakhon Nayok, Thailand were recruited and divided into 2 groups according to their left ventricular ejection fraction (LVEF) (< 50% vs. ≥ 50%) with LVEF < 50% considered as LVSD. Correlations among the clinical, laboratory and echocardiographic variables were analyzed. The factors associated with LVSD were explored with univariate and multivariate logistic regression analyses. Beta coefficient along with odds ratio and 95% confidence interval (CI) were calculated and the P value < 0.05 was considered significant. Results Among 103 subjects stratified as LVSD (n = 18, 17.5%). The mean (SD) age was 59.3 (12.7) years, and nearly halves were males. Preexisting CAD, diabetes (DM) and current smoking were 20 (19.4%), 63 (61.2%) and 23 (22.3%) patients, respectively. The median time of dialysis vintage was 12 (3, 24) months. Factors associated with LVSD and corresponding ORs with 95% CI by multivariate analysis were prior coronary artery disease (CAD) [5.08 (1.16, 22.19)], DM [6.36 (1.29, 31.49)], smoking [10.62 (2.17, 51.99)], neutrophil to lymphocyte ratio (NLR) > 3.6 [6.77 (1.41, 32.52)], and high serum phosphate [9.39 (2.16, 40.92)] were significantly associated with LVSD. Conclusions Prior history of CAD, DM, smoking, high NLR and serum phosphate levels were found to be associated with LVSD for our PD patients. The evidence from prospective study is needed to confirm the predictive value of these variables.

Abstract
OBJECTIVE Patients in intensive care units (ICU) have greater morbidity and mortality. We aimed to study neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in the ICU population. METHODS Medical and laboratory data of patients treated in ICU were retrospectively analyzed. Patients were divided into deceased and survived groups. RESULTS The NLR of survived and deceased groups were 3.6 (0.2-31) and 9.5 (1-40), respectively (p<0.001). The PLR of the survived group (111 [16-537]) was significantly lower than the PLR of the deceased (209 [52-1143]), (p<0.001). An NLR higher than 4.9 had 84% sensitivity and 67% specificity is selecting deceased patients (AUC:0.80, p<0.001). A PLR higher than 112 had 83% sensitivity and 52% specificity in predicting deadly cases (AUC:0.76, p<0.001). Both PLR and NLR were significantly and positively correlated with c reactive protein levels. CONCLUSION We suggest that physicians should pay particular attention to the treatment of patients in ICU with elevated NLR and PLR.

Abstract
Objectives: Inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been recently introduced as potential biomarkers for tumor pathogenesis, development and prognosis in solid tumors. Our aim was to assess the correlation of clinicopathological features and NLR and PLR in patients with papillary thyroid carcinoma (PTC). Methods: A total of 201 papillary thyroid carcinoma patients were divided into groups with a cut-off preoperative median NLR and PLR value of 1,92 and 123.9, respectively. The correlation of NLR and PLR and clinicopathological features including age, tumor size, extra-thyroidal extension, thyroid capsule invasion, surgical margin positivity, multifocality, bilaterality of the patients were analyzed. Results: The mean NLR and PLR were 2.11±0.94, 129.69±42.81, respectively. Larger tumor size and higher positivity of extra-thyroidal spread were correlated with higher NLR values. No significant relationship was found between NLR and age, presence of thyroid capsule invasion, surgical margin positivity, multifocality, bilaterality, and lymph node metastasis. Also no significant association was observed between the clinicopathological features and PLR. Conclusion: High NLR was found to correlate with tumor size and extra-thyroidal extension. NLR may be used as a marker to determine the clinical behavior of disease in patients with papillary thyroid carcinoma (PTC).

Abstract
Background and objectives Neutrophil to lymphocyte ratio is a simple, cost-effective and easily applicable inflammation indicator that is being used frequently in mortality, morbidity and prognosis studies in the recent years. We evaluated the relationship between neutrophil to lymphocyte ratio and postoperative pain in patients undergoing total hip arthroplasty and total knee arthroplasty. Material and methods We included 101 patients who preferred spinal anesthesia and intravenous patient-controlled analgesia in accordance and divided them into two groups, total hip arthroplasty and total knee arthroplasty. We recorded demographic information, duration of operation, length of hospital stay, analgesics consumption, neutrophil to lymphocyte ratio results and postoperative pain using Visual Analog Scale. Results The morphine consumption of the patients was as follows in group total hip arthroplasty and total knee arthroplasty: at the 4th hour: 7.38 mg, 7.80 mg; 8th hour: 12.19 mg, 13.29 mg; 12th hour: 16.94 mg, 19.18 mg; 24th hour: 25.97 mg, 27.98 mg; 48th hour: 36.38 mg, 39.59 mg. The Visual Analog Scale scores of the patients was as follows in group total hip arthroplasty and total knee arthroplasty: at the 4th hour: 4.10, 4.51; 8th hour: 3.02, 3.43; 12th hour: 2.29, 2.55; 24th hour: 1.90, 1.87; 48th hour: 1.08, 1.13. In group total hip arthroplasty, we found a statistically significant association between postoperative neutrophil to lymphocyte ratio and the Visual Analog Scale values on the 48th hour in a positive direction (r = 0.311; P = 0.031; P < 0.05). Conclusion Neutrophil to lymphocyte ratio can be accepted as a relatively objective method for the diagnosis of postoperative pain.

Abstract
Systemic inflammation is known to cause WBC abnormalities, specifically neutrophilia and lymphopenia. The neutrophil-to-lymphocyte ratio (NLR) is a simple and affordable biomarker that has been used in human clinical settings of sepsis but has not been investigated in veterinary species. We evaluated NLR in dogs with septic and nonseptic systemic inflammatory diseases and compared with a healthy dog population. An NLR ≥6 had an 84.39% sensitivity and 86.95% specificity to identify dogs with systemic inflammatory states; however, no ratio distinguished septic and nonseptic causes. The NLR was not associated with length of hospitalization, morbidity based on the acute patient physiologic laboratory evaluation scoring system, or mortality. The disassociation may be due to the retrospective nature of the study, including a restricted population size and acquisition of only a one-time blood sample. NLR is currently of limited use for diagnosis and prognosis in systemic inflammatory states in dogs, and larger, prospective studies are necessary to further evaluate NLR.

Abstract
Background To assess the usefulness of the neutrophil/lymphocyte ratio (NLR), a marker of inflammation and/or stress, for predicting weaning failure in patients receiving invasive mechanical ventilation (IMV), compared to levels of leukocytes and C-reactive protein (CRP). Methods This observational prospective cohort study was conducted from July 2013 to December 2016 in an intensive care unit in China, enrolling 269 consecutive patients receiving IMV. Patients underwent a spontaneous breathing trial (SBT) if they were ready to wean, and underwent extubation if they passed the SBT. The evaluated markers were measured immediately prior to SBT, and compared between weaning-failure and weaning-success patients. Receiver-operating characteristic (ROC) curve and logistic regression analyses were used to evaluate the ability of these markers to predict weaning failure. Results In all, 94 (34.9%) patients failed the weaning process (66 failed SBT and 28 presented with post-extubation respiratory distress). NLR was a better predictor of failure (area under the ROC curve, 0.69; 95% CI, 0.62-0.76) than leukocyte levels (0.60, 0.53-0.67) and CRP values (0.58, 0.51-0.65). NLR >11, leukocyte counts >10.5×109/L, and CRP >58 mg/L prior to weaning had the best combination of sensitivity (73%, 64%, and 63%, respectively), specificity (59%, 55%, and 63%), positive predictive value (49%, 43%, and 48%), negative predictive value (81%, 74%, and 76%), and diagnostic accuracy (64%, 58%, and 63%) for predicting weaning failure. However, only NLR >11 (odds ratio, 5.91; 95% CI, 3.08-11.33; P<0.001) was an independent predictor of weaning failure in the adjusted logistic regression model. Conclusions NLR may be a useful marker for predicting weaning failure, and weaning at NLR >11 might be considered with caution. Further study with a larger sample size and with weaning outcome as a variable of concern is warranted. Trial registration: ClinicalTrials.gov identifier: NCT02981589.

Abstract
Aptamers are synthetic molecules structured as single-stranded DNA or RNA oligonucleotides that can be designed to mimic the functional properties of monoclonal antibodies. They bind to the target molecules (typically soluble or cell-bound proteins) with high affinity (with picomolar to low nanomolar range) and specificity, and therefore can be an alternative to therapeutic antibodies or peptide ligands. This paper reviews published data regarding pharmacokinetics, pharmacodynamics and safety of aptamers from preclinical and clinical studies. Aptamers have been developed for the treatment of a variety of diseases, including cancer, macular degeneration,g cardiovascular disease, diabetes and anaemia of chronic diseases. There are several preclinical studies with unmodified aptamers, but the vast majority of aptamer trials in humans have been conducted with modified aptamers, because unmodified aptamers demonstrate metabolic instability, as well as rapid renal filtration and elimination. Various strategies have been developed to improve the pharmacokinetic profile of aptamers. Aside from chemical modification of nucleotides in order to stabilize them against nuclease degradation, the main modification to extend the half-life is pegylation. Therefore, the process of pegylation as well as its benefits and possible shortcomings will briefly be discussed.

Abstract
INTRODUCTION Although the effects of relatively high concentrations of endotoxin on endothelial activation/dysfunction and kidney markers has been described in literature, detailed insight in the LPS concentration-effect relationship, the magnitude, variability and timing of the response, and potential effects of endotoxemia on the kidneys is lacking. A study was performed to assess the effects of low- to moderate dose (0.5, 1 or 2ng/kg) endotoxemia on the endothelium and kidneys as measured by a panel of novel highly sensitive kidney injury markers. METHODS This was a randomized, double-blind, placebo-controlled study with single ascending doses of LPS (0.5, 1 or 2ng/kg) administered to healthy male volunteers (3 cohorts of 8 subjects, LPS:placebo 6:2). Endothelial measures included selectins, cell adhesion molecules, and thrombomodulin. Renal measures included novel, sensitive and specific biomarkers of acute kidney injury. RESULTS Endotoxin exposure resulted in consistent LPS dose-dependent responses in inflammatory markers, E- and P- Selectin, VCAM1, ICAM1, and thrombomodulin. The observed biological responses were transient, reaching a level of significance of at least <0.01 in the highest dose group and with an effect size which was dependent on the administered LPS dose. LPS-induced inflammatory and endothelial effects did not translate into a change in renal damage biomarkers, although at 2ng/kg LPS, subtle and transient biomarker changes were observed that may relate to (subclinical) tubular damage. DISCUSSION We demonstrated that administration of a single LPS dose of 2ng/kg to healthy volunteers results in significant inflammatory and endothelial responses, without inducing clinically relevant signs of kidney injury. These findings support the application of the human endotoxemia model in future clinical pharmacology studies.

Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio are superior to other inflammation-based prognostic scores in predicting the mortality of patients with gastrointestinal perforation. JA Clin Rep 2017; 3:49.

Abstract
Background The neutrophil to lymphocyte ratio (NLR) is gaining interest as an independent predictor of survival in patients with various clinical conditions. No study to date has reported an association between inflammation-based prognostic scores, including the Glasgow Prognostic Score (GPS), NLR, platelet to lymphocyte ratio (PLR), Prognostic Nutritional Index (PNI), and Prognostic Index (PI), and mortality in patients with gastrointestinal perforation (GIP). We compared the prognostic value of these measures. Findings A total of 32 patients with GIP were retrospectively enrolled. Patients were assessed according to the GPS, NLR, PLR, PI, and PNI. Multivariate analyses were performed to identify variables associated with mortality. Receiver operating characteristic (ROC) analyses were also performed. Overall survival rates (in-hospital mortality) were calculated using the Kaplan–Meier method, and differences in survival rates between groups were compared by the log-rank test. Multivariate analysis of significant variables revealed NLR (HR 1.257, 95% CI 1.035–1.527, P = 0.021) and PLR (HR 1.004, 95% CI 1.001–1.007, P = 0.016) at the time of admission to the intensive care unit to be independently associated with in-hospital mortality. AUC analysis revealed Sequential Organ Failure Assessment-Glasgow Coma Scale (SOFA-GCS) (0.73) to be superior to NLR (0.57) and PLR (0.58) for predicting mortality, and a high SOFA-GCS score was associated with reduced overall survival (P < 0.05). Conclusions NLR and PLR were superior to other inflammation-based prognostic scores in predicting the mortality of patients with GIP.

Abstract
OBJECTIVES No recommendations are currently available to help the clinician with the pharmacological management of intensive care unit (ICU) patients with elevated cardiac troponin (cTn) not linked to type 1 AMI. The aim of this study was to evaluate the pattern of cardiologic medications for patients with elevated cTnI in ICU not link to type 1 AMI and their effects on in-hospital mortality. MATERIAL AND METHODS A prospective observational cohort study conducted in two ICU units. Patients with increased plasma concentration of cTnI at admission not linked to type 1 AMI were consecutively included. RESULTS One hundred and ninety of the 835 patients admitted (23%) had an increased plasma concentration of cTnI not related to type 1 AMI. Antiplatelet therapy (AT) and statin were prescribed in 56 (29.5%) and 50 (26.3%) of patients, respectively. Others cardiologic medications were prescribed in less than 5% of all cases and were considered as contraindicated in more than 50% of cases. Antiplatelet therapy was the only cardiologic treatment associated with reduction of in-hospital mortality following uni- and multivariate analysis. The death rate was 23% and 40% in these patients treated with and without AT, respectively (aOR=0.39 [95% CI: 0.15-0.97]). CONCLUSIONS Statin and AT were frequently prescribed to patients with a cTnI elevation not linked to type 1 AMI. This study suggests that AT in patients with an increased plasma concentration of cTnI, not related to type 1 AMI in ICU, could reduce in-hospital mortality.

Abstract
INTRODUCTION The neutrophil-to-lymphocyte ratio (NLR) is a readily available biomarker associated with recurrence and survival in various diseases. The objective of this study was to investigate the relationship between NLR and pulmonary tuberculosis (PTB) retreatment. MATERIAL AND METHODS This was a case-control study that included 306 newly diagnosed cases of PTB in the clinical database of the Infectious Hospital of Wuxi from December 2009 to December 2011. Of the 306 patients, a total of 68 cases were followed up with TB retreatment. The remaining 238 PTB patients who completed anti-TB treatment and were cured without retreatment were selected as controls. RESULTS According to the ROC curve, the best cut-off value of NLR was 2.53, with a sensitivity of 70.6% and a specificity of 45.4%. The NLR ≥ 2.53 before anti-TB treatment was associated with PTB retreatment (OR = 1.994, 95% CI: 1.116-3.564; adjusted OR (AOR) = 2.409, 95% CI: 1.212-4.788). The retreatment rates with NLR ≥ 2.53 and NLR < 2.53 were 27.1% and 15.5%, respectively, with a significant difference (log-rank test; p = 0.010). Additionally, cavitation on chest X-ray (OR = 2.922, 95% CI: 1.654-5.411; AOR = 2.482, 95% CI: 1.230-5.007), history of smoking (OR = 2.202, 95% CI: 1.158-3.493; AOR = 2.321, 95% CI: 1.135-4.745) and age ≥ 60 (OR = 3.828, 95% CI: 1.626-9.015; AOR = 2.931, 95% CI: 1.122-7.653) were also associated with PTB retreatment. CONCLUSIONS NLR ≥ 2.53 is predictive of PTB retreatment. Otherwise, initial cavitation on chest X-ray, history of smoking, and age of ≥ 60 are also risk factors for PTB retreatment.

Abstract
Aim: We aimed to reveal the correlation of NLR rate, RDW and MPV values and with the findings of PET/CT regarding the prediction of disease progression and the clinical characteristics. Materials and methods: The treatment naive sarcoidosis cases, of whose PET/CT have been taken due to mediastinal lymphadenopathy of whose diagnosis have been confirmed by biopsy, were included in the study. Hematological parameters, clinical, radiological and PET/CT findings are evaluated. Results: 40 sarcoidosis and 40 healthy control cases were included in the study. NLR, RDW, MPV and the sedimentation values in the sarcoidosis group were determined statistically significantly higher. In patients having parenchymal involvement in PET/CT, the values of FVC%, DLCO, DLCO%, DLCO/VA and DLCO/VA% were determined significantly lower. High NLR and PET/CT LAP SUVmax values and low DLCO% values are statistically significantly correlated with one-year disease progression. For predicting the progression, for the NLR cut-off value 3.20, the area under the curve was determined as 0.79 (CI 62.2-96.5), sensitivity as 80.0%, specificity as 76.7% and for the PET/CT SUVmax cut-off value 9.5, the area under the curve was determined as 0.71 (CI 46.6-95.9), sensitivity as 70.0%, specificity as 82.1%. Conclusion: We determined that the values observed in routine hematologic examinations such as NLR, RDW and MPV, were high in sarcoidosis cases. In addition, the values of NLR, DLCO% and PET/CT SUVmax might be used in predicting the progression. At the same, once again we showed that the lung parenchyma involvement in PET/CT correlates with many pulmonary function parameters. (Sarcoidosis Vasc Diffuse Lung Dis 2017; 34: 242-250)

Abstract
Because of similar clinical manifestations and laboratory findings, differential diagnosis of pulmonary embolism and community-acquired pneumonia (CAP) is generally difficult. Therefore, this study was conducted to find good markers for the easy, cheap, and fast differential diagnosis of pulmonary embolism and CAP. Thirty-four patients diagnosed with pulmonary embolism and 38 patients with CAP who were admitted to either emergency department or chest diseases outpatient clinic were included in this study. On admission and third day, complete blood count, C-reactive protein (CRP), erythrocyte sedimentation rate, procalcitonin (PCT), and D-dimer levels of each patient were measured. Neutrophil-to-lymphocyte ratio (NLR) was calculated using the formula NLR = neutrophil count/lymphocyte count. NLR/D-dimer and PCT/D-dimer ratios were also calculated. First day neutrophil count (P = 0.005), NLR (P = 0.002), CRP (P < 0.001), erythrocyte sedimentation rate (P < 0.001), PCT (P < 0.001), NLR/D-dimer (P < 0.001), and PCT/D-dimer (P < 0.001) levels were higher in patients with CAP compared with patients with pulmonary embolism. In stepwise logistic regression analysis done with all the parameters used for the differential diagnosis of pulmonary embolism and CAP, CRP, PCT/D-dimer, and NLR/D-dimer were found to be independent predictive factors for the presence of CAP. Among these factors, NLR/D-dimer ratio was found to be the most sensitive (97.4%) to have the highest negative predictive value 96.7% and to be the most accurate (area under curve = 0.921) (91.7%) parameter for the differential diagnosis of pulmonary embolism and CAP. In this study, NLR/D-dimer ratio was found to be more sensitive and more selective with negative predictive value and area under curve for the differential diagnosis of pulmonary embolism and CAP compared with other laboratory tests.

Abstract
Endothelial expression of cell adhesion molecules (CAMs) plays an important role in atherosclerosis. Atherosclerosis is increased in hyperinsulinemic states, but whether insulin per se is proatherogenic remains unclear. To investigate the effects of hyperinsulinemia on CAM expression, plasma levels of ICAM-1, VCAM-1 and E-selectin were measured before and after forearm infusion of insulin in healthy subjects. Insulin administration for 2 h resulted in signifi-cant hyperinsulinemia, whereas no significant change was observed in soluble CAMs (all p > 0.05). Because insulin stimulates endothelial release of both endothelin-1 (ET-1) and nitric oxide (NO), which may modulate the expression of CAMs, we also investigated the response of CAMs to ET-1 receptor blockade, alone and in combination with NO synthesis inhibition. ET-1 receptor blockade during hyperinsulinemia resulted in a vasodilator response, but did not affect soluble CAMs (all p > 0.05). Superimposition of NO inhibition by l-NMMA reversed the vasodilator effect of ET-1 blockade, without affecting soluble CAMs (all p > 0.05). In conclusion, acute hyperinsulinemia, alone or during ET-1 and NO pathway blockade, does not affect soluble CAMs. These results do not support a direct effect of insulin on endothelial cells to affect leukocyte adhesiveness to the vascular wall.

Abstract
BACKGROUNDS The neutrophil-lymphocyte ratio (NLR) is a simple and low-cost index that may be a benchmark for systemic inflammatory response and antitumor immunity. The goal of the study was to investigate the prognostic value of preoperative NLR in patients with lung adenocarcinoma after complete resection. METHODS The subjects were 361 consecutive patients with lung adenocarcinoma who underwent complete resection between 2000 and 2009. Perioperative clinical and laboratory data were evaluated retrospectively. The cohort was divided using the cut-off value for preoperative NLR identified in receiver operating characteristic analysis. Correlations of NLR with clinicopathological characteristics and prognosis were examined. RESULTS A high NLR was significantly correlated with a smoking history >10 pack-years (p = 0.023), pathological stage II or III (p < 0.001), lymphatic invasion (p = 0.003), and pleural invasion (p = 0.039). In univariate analysis, the high NLR group had significantly lower 5-year overall survival (86.0 vs. 77.1 %, p < 0.001) and 5-year recurrence-free survival (75.1 vs. 59.9 %, p < 0.001). Multivariate analysis showed that NLR was an independent prognostic factor (hazard ratio 1.822, 95 % confidence interval 1.133-2.931, p = 0.013). CONCLUSION These results show that preoperative NLR is an independent prognostic factor in patients with lung adenocarcinoma after complete resection. NLR may reflect host immunity and systemic inflammation that facilitates tumor growth.
