Background. Neutrophil to lymphocyte ratio (NLR) is a new inflammatory marker; the relationship between NLR and adverse cardiovascular (CV) prognosis has been gradually emphasized in the general population. However, their association in peritoneal dialysis (PD) patients remains unclear. Methods. From January 1, 2010, to May 31, 2017, a total of 1652 patients were recruited. NLR was categorized in triplicates: NLR≤2.74, 2.74<NLR≤3.96, and NLR>3.96. Kaplan-Meier cumulative incidence curve and multivariable COX regression analysis were used to determine the relationship between NLR and the incidence of adverse CV outcome, while a competitive risk model was applied to assess the effects of other outcomes on adverse CV prognosis. Besides, forest plot was investigated to analyze the adverse CV prognosis in different subgroups. Results. During follow-up, 213 new-onset CV events and 153 CV disease (CVD) deaths were recorded. Multivariable COX regression models showed that the highest tertile of NLR level was associated with increased risk of CV events (HR=1.39, 95%CI=1.01‐1.93, P=0.046) and CVD mortality (HR=1.81, 95%CI=1.22‐2.69, P=0.003), while compared to the lowest tertile. Competitive risk models showed that the differences in CV event (P<0.001) and CVD mortality (P=0.004) among different NLR groups were still significant while excluding the effects of other outcomes. In subgroups, with each 1 increased in the NLR level, adjusted HR of new-onset CV event was 2.02 (95%CI=1.26−3.23, P=0.003) and CVD mortality was 2.98 (95%CI=1.58−5.62, P=0.001) in the younger group (age<60 years). Conclusions. NLR is an independent risk factor for adverse CV prognosis in PD patients younger than 60 years old.

Background. The study is aimed at exploring the relationship of platelet-to-lymphocyte (PLR), all-cause, and cardiovascular disease (CVD) mortality in peritoneal dialysis (PD) patients based on gender. Methods. A total of 1438 PD patients from January 1,2007 to December 31, 2014 in PD center at The First Affiliated Hospital, Sun Yat-sen University, were included. Patients were followed up until December 31, 2019. The endpoint was all-cause mortality and CVD mortality. Cox proportional hazards regression models were used to evaluate the association of PLR with all-cause and CVD mortality to calculate hazard ratios (HR) and 95% confidence intervals (CI). Results. After a median of 48.9 (interquartile range [IQR]: 23.4-79.3) months of follow-up, 406 (28.2%) patients died based on all-cause death, among which 200 (49.3%) patients died from CVD. In the multivariate Cox regression model, we found that PLR was independently related to an increased risk of CVD mortality only in female PD patients, with HR of 1.003 (95% CI: 1.001-1.006). Interaction test showed that the correlation between PLR level for all-cause and CVD mortality varied with gender ( p = 0.042 and p = 0.012 , respectively). Conclusion. Higher PLR was associated with a higher risk of CVD mortality in female PD patients.

BackgroundHepatocellular carcinoma (HCC) is the most common pathological type of primary liver cancer. The lack of prognosis indicators is one of the challenges in HCC. In this study, we investigated the combination of tertiary lymphoid structure (TLS) and several systemic inflammation parameters as a prognosis indicator for HCC.Materials and MethodsWe retrospectively recruited 126 postoperative patients with primary HCC. The paraffin section was collected for TLS density assessment. In addition, we collected the systemic inflammation parameters from peripheral blood samples. We evaluated the prognostic values of those parameters on overall survival (OS) using Kaplan-Meier curves, univariate and multivariate Cox regression. Last, we plotted a nomogram to predict the survival of HCC patients.ResultsWe first found TLS density was positively correlated with HCC patients’ survival (HR=0.16, 95% CI: 0.06 − 0.39, p &lt; 0.0001), but the power of TLS density for survival prediction was found to be limited (AUC=0.776, 95% CI:0.772 − 0.806). Thus, we further introduced several systemic inflammation parameters for survival analysis, we found neutrophil-to-lymphocyte ratio (NLR) was positively associated with OS in univariate Cox regression analysis. However, the combination of TLS density and NLR better predicts patient’s survival (AUC=0.800, 95% CI: 0.698-0.902, p &lt; 0.001) compared with using any single indicator alone. Last, we incorporated TLS density, NLR, and other parameters into the nomogram to provide a reproducible approach for survival prediction in HCC clinical practice.ConclusionThe combination of TLS density and NLR was shown to be a good predictor of HCC patient survival. It also provides a novel direction for the evaluation of immunotherapies in HCC.

Introduction: There are conflicting reports regarding whether daytime napping is a risk factor for cardiovascular events. The purpose of this study was to investigate the relationship between daytime napping and incident stroke within a community-based cohort study. Hypothesis: We assessed the hypothesis that the duration and the frequency of daytime napping may be associated with incident stroke. Methods: Participants without previous stroke were enrolled in the present prospective study from the Sleep Heart Health Study (registration number, NCT00005275). Daytime napping were assessed with a self-reported Sleep Habits Questionnaire. Duration of daytime napping was divided into the following categories: no naps, 0-30 min, 31-60 min, or >60 min. Frequency of naps were categorised as: no naps, 1-2 times/week, 3-4 times/week, 5-6 times/week, or daily. After combining nap duration and frequency, participants were further divided into groups with regular long naps (≥5 times per week and >30 min), regular short naps (≥5 times per week and ≤30 min), irregular naps or no naps. Subsequently, participants were followed up until the first stroke occurred between the date of the completed questionnaire and the final censoring date. Cox regression analysis was used to estimate the relationship between daytime napping and incident stroke. Results: The present study enrolled 4757 participants, of which 220 participants (4.6%) experienced incident stroke during an average follow-up of 10.6 years. There was a higher rate of stroke among participants taking longer and more frequent naps than others. Multivariate Cox regression analysis indicated that, when compared with participants with no naps, those with a nap duration of ≥60 min or of 31-60 min had a higher risk of stroke (HR, 2.182; 95% CI, 1.443-3.301; HR, 1.594; 95% CI, 1.003-2.531, respectively). Moreover, there was an increased risk of stroke among participants taking daily daytime naps (HR, 1.563; 95% CI, 1.059-2.307) or napping 5-6 times per week (HR, 1.548; 95% CI, 1.026-2.335) than those with no naps. And after combining nap duration and frequency, regular long naps and regular short naps were also associated with higher risk of incident stroke (HR, 1.903; 95% CI, 1.182-3.065; HR, 1.451; 95% CI, 1.010-2.084, respectively). Conclusions: In conclusion, daytime napping of long duration and high frequency may increase the risk of incident stroke in community. Modification of sleep habits may improve the life quality among those elderly community-based population.

IntroductionPrevious epidemiological studies have reported on the prevalence of diabetic kidney disease (DKD) and diabetic retinopathy (DR) from India. The aim of this study is to evaluate the effect of DKD on the development of new-onset DR and sight-threatening diabetic retinopathy (STDR) in Asian Indians with type 2 diabetes (T2D).Research design and methodsThe study was done on anonymized electronic medical record data of people with T2D who had undergone screening for DR and renal work-up as part of routine follow-up at a tertiary care diabetes center in Chennai, South India. The baseline data retrieved included clinical and biochemical parameters including renal profiles (serum creatinine, estimated glomerular filtration rate (eGFR) and albuminuria). Grading of DR was performed using the modified Early Treatment Diabetic Retinopathy Study grading system. STDR was defined as the presence of proliferative diabetic retinopathy (PDR) and/or diabetic macular edema. DKD was defined by the presence of albuminuria (≥30 µg/mg) and/or reduction in eGFR (<60 mL/min/1.73 m2). Cox regression analysis was used to evaluate the hazard ratio (HR) for DR and STDR.ResultsData of 19 909 individuals with T2D (mean age 59.6±10.2 years, mean duration of diabetes 11.1±12.1 years, 66.1% male) were analyzed. At baseline, DR was present in 7818 individuals (39.3%), of whom 2249 (11.3%) had STDR. During the mean follow-up period of 3.9±1.9 years, 2140 (17.7%) developed new-onset DR and 980 individuals with non-proliferative DR (NPDR) at baseline progressed to STDR. Higher serum creatinine (HR 1.5, 95% CI 1.3 to 1.7; p<0.0001), eGFR <30 mL/min/1.73 m2 (HR 4.9, 95% CI 2.9 to 8.2; p<0.0001) and presence of macroalbuminuria >300 µg/mg (HR 3.0, 95% CI 2.4 to 3.8; p<0.0001) at baseline were associated with increased risk of progression to STDR.ConclusionsDKD at baseline is a risk factor for progression to STDR. Physicians should promptly refer their patients with DKD to ophthalmologists for timely detection and management of STDR.

Objectives: The relationship between a fragmented QRS (fQRS) and clinical outcomes in patients with hypertrophic cardiomyopathy (HCM) remains unclear. This study aimed to investigate the prognostic significance of fQRS in patients with HCM. Methods: Between 2000 and 2012, 326 unrelated patients with HCM (72% male with a mean age of 52 years) were included and were divided into 2 groups: those with fQRS and those without fQRS. Results: A total of 105/326(32.2%) patients with HCM presented with fQRS at enrollment. During a follow-up of 5.3 ± 2.4 years, 33 patients died, 30 of cardiovascular disease (CVD). Cox regression analysis revealed that fQRS predicted a higher risk of all-cause mortality (adjusted hazard ratio [HR] 2.24; 95% confidence interval [CI] 1.08-4.64; p = 0.030) and CVD mortality (adjusted HR 2.68; 95% CI 1.22-5.91; p = 0.014). Our study also showed that fQRS increased the risk of heart failure-related death (adjusted HR 3.75; 95% CI 1.24-11.30; p = 0.019). Conclusions: Our results indicate that fQRS is associated with adverse clinical outcomes in patients with HCM.

e16020 Background: Advanced urothelial carcinoma (UC) patients have a poor prognosis. In the first and second line UC treatment setting, we investigated real world outcomes and evaluated the prognostic role of the neutrophil to lymphocyte ratio (NLR). Methods: A retrospective analysis was performed on advanced UC patients treated with systemic therapy. Overall response rates (ORR), time to treatment failure (TTF) and overall survival (OS) were calculated. Cox regression analysis was performed to examine the association between baseline NLR (low NLR<3 vs high NLR≥3) and TTF and OS. Results: We evaluated 233 advanced UC patients. In the first line setting, the ORR was 25%. Median TTF and OS were 6.9 mo and 9 mo, respectively. Low baseline NLR was significantly associated with improved 8.3 mo median TTF, versus 5.8 mo for high NLR patients (p=0.05). Low NLR was significantly correlated with a longer median OS of 13.1 mo, in comparison to 8.2 mo in patients with high NLR (p=0.007). In the second line, an ORR of 22%, a median TTF of 4.1 mo and a median OS of 8 mo were observed. Low NLR in the second line was significantly associated with improved median TTF at 7.9 mo, versus 3.6 mo for patients with high NLR (p=0.03). Second line low NLR was also significantly associated with a longer median OS of 12.2 mo, in comparison to 6.8 mo in patients with high NLR (p=0.003). Conclusions: In this real world analysis of advanced UC patients, first line outcomes were lower than expected, while response rates in the second line compared favorably to the literature, suggesting a highly selected patient population actually receives second line treatment. A low baseline NLR in the first and second line is associated with improved TTF and OS and warrants further prospective evaluation. [Table: see text]

Background This study aimed to evaluate the correlation between neutrophil to lymphocyte ratio (NLR) with overall survival (OS) of esophageal squamous cell carcinoma (ESCC) patients. Method Records of patients with diagnosed ESCC were reviewed. Leukocyte counts and patients' characteristics were extracted from their clinical records to calculate NLR. Correlation between NLR and baseline characteristics with overall survival (OS) was then analyzed using Cox regression. The patients were then separated into higher and lower NLR groups according to median NLR. OS was further compared between the 2 groups. Results A total of 1281 patients were included in the study. Cox regression analysis showed a significant correlation of NLR with OS of ESCC patients. The median pretreatment NLR was identified as 2.86. Higher NLR was associated with worse prognosis in terms of OS. Conclusions Pretreatment NLR is independently associated with OS of ESCC patients. Therefore, NLR may be used as a predictive indicator for pretreatment evaluation and adjustment of treatment regimen.

Background. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are markers for systemic inflammation condition. Although NLR has emerged as a risk factor for poor survival in end-stage renal disease (ESRD) patients, the relationship between PLR and mortality is still unknown. We aimed to explore the interaction of NLR and PLR in predicting mortality in hemodialysis (HD) patients. Method. We enrolled 360 HD patients for a 71-month follow-up. The endpoint was all-cause and cardiovascular (CV) mortality. Pearson correlation analysis was conducted to evaluate the relationship between factors and NLR or PLR. Kaplan-Meier curves and Cox proportional analysis were used to assess the prognostic value of NLR and PLR. Results. NLR was positively correlated with neutrophil and negatively correlated with lymphocyte, hemoglobin, and serum albumin. PLR was positively correlated with neutrophil and platelet and negatively correlated with lymphocyte and hemoglobin. In multivariate Cox regression, a higher NLR level was independently associated with all-cause mortality (OR 2.011, 95% CI 1.082-3.74, p = 0.027 ), while a higher PLR level might predict CV mortality (OR 2.768, 95% CI 1.147-6.677, p = 0.023 ) in HD patients. Conclusion. NLR and PLR are cheap and reliable biomarkers for all-cause and CV mortality to predict survival in HD patients.

Objective: We sought to explore if there is an association between neutrophil-to-lymphocyte ratio (NLR) and treatment failure in patients with peritoneal dialysis-associated peritonitis (PDAP).Methods: Our cohort involved 337 episodes of PDAP experienced by 202 patients who were undergoing continuous ambulatory peritoneal dialysis at a single center from 1 July 2013 to 30 June 2018. The exposures were log-transformed NLR and a categorical variable grouped by the tertiles of NLR levels (T1, &lt;3.75; T2, 3.75–6.53; and T3, &gt;6.53) at baseline. Generalized estimating equation (GEE) and restricted cubic spline (RCS) analyses were done to determine the association between NLR and treatment failure, defined as catheter removal or all-cause mortality during therapy.Results: After adjusting for other potential predictors, the log-transformed NLR exhibited an incremental relationship with the risk of treatment failure (odds ratio, 1.82; 95% confidence interval, 1.05–3.15). RCS analyses showed that the relationship was positively and linearly correlated (P for nonlinearity = 0.104). As a three-level categorical variable, in reference to T1, the T3 of NLR showed a 3.41-fold increased venture of treatment failure in fully adjusted model. Subgroup analyses suggested that the prognostic relevance of NLR in PDAP was particularly significant in gram-negative peritonitis.Conclusions: A greater level of NLR at baseline was remarkably associated with a higher incidence of treatment failure among PDAP episodes regardless of other potential risk factors.
