Abstract
Background Colorectal cancers (CRC) are one of the most common tumors that are being researched for new biomarkers worldwide. In this context, studies are being carried out to estimate whether various hematological parameters can be used for predicting prognosis. In this study, our aim was to evaluate the relation between platelet (PLT) levels as well as neutrophil-to-lymphocyte ratio (NLR), platelet (PLT)-to-lymphocyte ratio (PLR), and Lymphocyte-to-CRP ratio (LCR) which are easily accessible inflammatory response indicators. Methods In this retrospective cross-sectional study, 111 patients diagnosed as colorectal adenocarcinoma were included. Patients with clinical evidence of an infection, recurrent colorectal cancer, previous history of a hematological disease, and a neoadjuvant chemo/radiotherapy were excluded. Demographic features such as age, gender, and histopathologic parameters such as tumor size, surgical margin status (proximal, distal, and radial), the presence of serosal inflammation, lymphovascular invasion (LVI), perineural invasion (PNI), lymph node metastasis (LNM) and distant metastasis, preoperative blood sample analysis, and CRP levels were noted. Statistical analysis for the association between hematologic parameters platelet (PLT) levels as well as neutrophil-to-lymphocyte ratio (NLR), platelet (PLT)-to-lymphocyte ratio (PLR), and Lymphocyte-to-CRP ratio (LCR) and histopathological features were done. Results Among 111 patients, the mean age was 65.37, and the mean tumor size was 5.41 cm. Lymphovascular invasion, perineural invasion, radial surgical margin positivity, lymph node metastasis, localization, and stage were statistically significantly related to the number of platelets. For NLR, PNI (p=0.001), LNM (p=0.048), and stage (early/advanced) (p=0.045) were significantly related. None of the parameters were related to PLR and LCR. Conclusion Perineural invasion, lymph node metastasis, and the stage of the tumor could be the major histopathological features that could be related to hematologic parameters; however, this should be researched by larger studies as if they can be used as prognostic markers.

Abstract
BACKGROUND Patients with pan-peritonitis (PP) due to colorectal perforation have high mortality rate because colorectal perforation causes septic shock. The association between total steroid intake (TSI) and hospital mortality of such patients is not clear. METHODS One hundred forty-two patients who underwent surgery for PP due to colorectal perforation were reviewed. Patients were divided into two groups by 8000 mg of TSI. The cut-off value of TSI was determined using a receiver operating characteristic curve for hospital mortality. RESULTS The cut-off value of TSI for hospital mortality was 8000 mg. Patients with TSI>8000 mg had high rate of hemodialysis, hospital mortality, and elevated neutrophil ratio (>95%) compared with those with TSI≤8000 mg. Multivariate analyses revealed that TSI (>8000/≤8000, mg) (OR, 9.669; 95% CI, 1.011-92.49; P = .049) was significantly associated with hospital mortality as well as bleeding volume (>1000/≤1000, mL) (OR, 26.08; 95% CI, 3.566-190.4; P = .001), lymphocyte ratio (≤4/>4, %) (OR, 7.988; 95% CI, 1.498-42.58; P = .015) and C-reactive protein (≤7.5/>7.5, mg/dL) (OR, 41.66; 95% CI, 4.784-33.33; P = .001). DISCUSSION There was a significant association between TSI and hospital mortality in patients with PP due to colorectal perforation as well as intraoperative bleeding and systemic inflammatory markers.

A Novel Clinical Nomogram for Predicting Overall Survival in Patients with Emergency Surgery for Colorectal Cancer. J Pers Med 2023; 13:jpm13040575. [PMID: 37108961 PMCID: PMC10145637 DOI: 10.3390/jpm13040575] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 03/14/2023] [Accepted: 03/21/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Long-term survival after emergency colorectal cancer surgery is low, and its estimation is most frequently neglected, with priority given to the immediate prognosis. This study aimed to propose an effective nomogram to predict overall survival in these patients. MATERIALS AND METHODS We retrospectively studied 437 patients who underwent emergency surgery for colorectal cancer between 2008 and 2019, in whom we analyzed the clinical, paraclinical, and surgical parameters. RESULTS Only 30 patients (6.86%) survived until the end of the study. We identified the risk factors through the univariate Cox regression analysis and a multivariate Cox regression model. The model included the following eight independent prognostic factors: age > 63 years, Charlson score > 4, revised cardiac risk index (RCRI), LMR (lymphocytes/neutrophils ratio), tumor site, macroscopic tumoral invasion, surgery type, and lymph node dissection (p < 0.05 for all), with an AUC (area under the curve) of 0.831, with an ideal agreement between the predicted and observed probabilities. On this basis, we constructed a nomogram for prediction of overall survival. CONCLUSIONS The nomogram created, on the basis of a multivariate logistic regression model, has a good individual prediction of overall survival for patients with emergency surgery for colon cancer and may support clinicians when informing patients about prognosis.

Abstract
BackgroundThe preoperative elevated neutrophil-to-lymphocyte ratio (NLR) was reported to be associated with poorer outcomes after cancer and cardiovascular surgeries. It is unclear, however, if the predictive value is particular or if it may be applied to other types of surgery. We aimed to assess the prognostic value of preoperative NLR levels for morbidity and mortality after various surgery and determine an optimal threshold for NLR.MethodsWe conducted a cohort analysis on patients receiving surgery at Sichuan University West China Hospital between 2018 and 2020. Multivariable piecewise regression analysis were used to determine the optimal cutoff value of NLR. Subgroup analysis were performed to verify the correlation. Sensitivity analysis was used to explore the effect of different thresholds.ResultsWe obtained data from 136,347 patients. The optimal cutoff of NLR was determined as 3.6 [95% CI (3.0, 4.1)] by piecewise regression method. After multivariable adjustment, preoperative high NLR remained significantly associated with increased in-hospital mortality (aOR, 2.19; 95% CI, 1.90–2.52; p < 0.001) and ICU admission after surgery (aOR, 1.69; 95% CI, 1.59–1.79; p < 0.001). Subgroup analyses confirmed the predictive value of high NLR in multiple surgical subgroups, including general, orthopedic, neurosurgical, and thoracic surgery subgroups, otorhinolaryngology, head and neck surgery, and burn plastic surgery. A NLR threshold of 3.6 gave excellent predictive value, whether employed alone or added in an extended model.ConclusionsIn conclusion, the association of elevated NLR with higher mortality and ICU admission can be extended to a wider range of procedures. NLR threshold of 3.6 could provide good prognostic value for the prognostic model.

Abstract
INTRODUCTION The management of inflammation after colorectal surgery is important to decrease the susceptibility to postoperative complications. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in the peripheral blood are known as two important inflammatory markers. In this study we evaluated and compared colorectal laparoscopy and laparotomy based on the PLR and NLR. METHODS Totally, 76 patients were divided into two groups including patients who underwent laparoscopy (45 cases) or laparotomy (31 cases). The PLR and NLR were calculated based on cell blood count analysis of preoperative and postoperative day (POD) one and three in both groups. Statistical analysis was performed using SPSS software version 22. RESULTS The PLR and NLR have no significant association with age, gender and tumor site (p > 0.05). However, both ratios were significantly increased in laparotomy patients at POD1 compared with the laparoscopy patients (p < 0.05). According to the two by two comparisons, the preoperative and postoperative PLR were significantly different in the laparotomy group (p < 0.05) but not in the laparoscopy group (p > 0.05). However, the preoperative and postoperative NLR were significantly different in both laparoscopy and laparotomy groups (p < 0.05). CONCLUSION The NLR and PLR markers indicated that laparoscopy can be a better choice for colorectal surgery due to lower induction of inflammation compared with laparotomy.

Abstract
The clinical significance of hemoglobin-to-red blood cell distribution width (Hb/RDW) for the diagnosis of nasopharyngeal cancer (NPC) has not been reported yet. This study aimed to evaluate the value of preoperative Hb/RDW, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) for the diagnosis of NPC.A total of 180 NPC patients (NPC group) and 149 healthy subjects (control group) were recruited to assess the value of Hb/RDW, NLR, and PLR for the diagnosis of NPC.It was noted that NLR and PLR were significantly higher in the NPC group than those in the control group (P < .001); however, Hb/RDW was lower in the NPC group compared with that in the control group (P < .001). NLR was also remarkably different between patients of stage I+II and those of stage III+IV (P = .043), and that was different in patients with lymph node metastases or not (P = .030). Besides, PLR was significantly different in patients with serosal invasion or not (P = .031). In receiver operating characteristic curve, compared with Hb/RDW alone (sensitivity, 66.67%; specificity, 85.23%), the sensitivity (67.78%, 72.78%) and specificity (89.62%, 90.6%) of Hb/RDW with NLR and PLR were both increased. Furthermore, Hb/RDW combined with NLR area under the ROC (AUC), 0.824; 95% confidence interval (CI): 0.779-0.864, P = .0080) or PLR (AUC: 0.851, 95% CI: 0.808-0.888, P = .0002) had a greater AUC value for the diagnosis of NPC compared with Hb/RDW alone (AUC: 0.781, 95% CI: 0.732-0.824).Hb/RDW can be used as a valuable indicator for auxiliary diagnosis of NPC. Preoperative Hb/RDW combined with NLR or PLR is of great significance in the auxiliary diagnosis and pathological staging of NPC.

Abstract
Minute clear cell renal cell carcinoma (MccRCC) has a diameter of <1.5 cm and can be diagnosed using multi-slice spiral CT (MSCT). Recently, the role of the neutrophil-lymphocyte ratio (NLR) in the development of MccRCC has attracted attention. This study aimed to further explore the relationship between the NLR and MccRCC.This was a prospective study of 100 patients who were diagnosed with MccRCC using MSCT at Urumqi Friendship Hospital, China. The study investigated a series of pretreatment factors, including NLR and patients' general clinical data. Statistical methods employed included Pearson's chi-square test, Spearman-rho correlation test, Cox regression analysis, and receiver operator characteristic curve analysis.Based on Pearson's χ2, Spearman-rho test, and univariate/multivariate Cox regression analysis, the overall survival of patients with MccRCC was shown to be significantly related to NLR (P < .001). NLR (hazard ratio = 50.676, 95%CI, 17.543-146.390, P < .001) is a significant independent risk-factor for MccRCC. A receiver operator characteristic curve was plotted to examine specificity and sensitivity between NLR and MccRCC (area under curve = 0.958, P < .001).The level of the NLR plays a crucial role in the survival of patients with MccRCC, as diagnosed with MSCT. The higher the NLR, the worse the prognosis for patients with MccRCC.

Abstract
Background: Inflammatory factors and nutritional status are critical to the prognosis of colorectal cancer patients. This study aimed to investigate the prognostic value of the combination of preoperative lymphocytes, albumin, and neutrophils (LANR) in patients with resectable colorectal cancer. Methods: A total of 753 patients with pathologically diagnosed primary colorectal cancer were included in the study. The value of LANR was defined as follows: LANR, lymphocyte × albumin/neutrophil. The ROC curve, subgroup analysis and Cox proportional hazard regression analysis were used to assess the prognostic value of LANR in overall survival and progression-free survival. Results: The median age of the patients was 60 years (range 52–67 years). In overall survival, the area under the curve of LANR was 0.6276, and the HR (95% CI) was 0.551 (0.393–0.772). And in progression-free survival, the area under the curve of LANR was 0.5963, and the HR (95% CI) was 0.697 (0.550–0.884). The results indicate that preoperative LANR may be a reliable predictor of overall and progression-free survival in resectable colorectal cancer patients. Conclusions: LANR is an important prognostic indicator for patients with resectable colorectal cancer, and it can also provide a reference for clinicians and patients to choose a treatment plan.

Abstract
Background: Systemic inflammatory status is known as an important factor of colorectal cancer prognosis. Our study aimed to evaluate the performances of inflammation biomarker ratios as classification models of seven outcomes in patients with colorectal cancer. Methods: A retrospective cohort study was conducted on subjects with colorectal cancer over five years at a single center in Transylvania, Romania. Seven derived ratios were calculated based on laboratory data: neutrophil-to-lymphocyte (NLR), derived neutrophil-to-lymphocyte (dNLR), platelet-to-lymphocyte (PLR), lymphocyte-to-monocyte (LMR) and albumin-to-globulin (AGR) ratios, Systemic Immune Inflammation Index (SII) and Prognostic Nutritional Index (PNI). The utility of these ratios as predictors for seven outcomes was further evaluated in multivariable regression models. Results: Our study shows that the evaluated ratios exhibit specific performances for individual outcomes, proving a fair ability as screening tools (NLR and dNLR for survival, T stage and M stage; NLR and SII for T stage; and PLR for M stage). A dNLR over 3.1 (OR = 2.48, 95% CI (1.421 to 4.331)) shows predictive value for survival. A value of NLR over 3.10 (OR = 1.389, 95% CI (1.061 to 1.817)) is positively associated with an advanced T stage, while LMR is negatively related to the T stage (OR = 0.919, 95% CI (0.867 to 0.975)). NLR over 4.25 (OR = 2.647, 95% CI (2.128 to 3.360)) is positively associated with, while PNI is negatively related (OR = 0.970, 95% CI (0.947 to 0.993)) to, the M stage. Conclusion: Each of the evaluated ratios possesses prognostic value for certain outcomes considered, but the reported models need external validation to recommend their clinical practice utilization.

Abstract
BACKGROUND A preoperative marker for morbidity in patients with colorectal cancer would help to risk stratify patients and allow for timely intervention to avert poor outcomes. We conducted this study to evaluate preoperative lymphocyte-white blood cell ratio (LWR) as a marker of postoperative morbidity. METHODS A prospective cohort of patients who underwent elective surgery for colorectal cancer was reviewed. Three morbidity-related outcomes were described-overall morbidity, multiple morbidities, and severe morbidity, defined as Clavien-Dindo Class ≥3. Univariable and multivariable analyses of presurgical predictors of these three outcomes were performed. Preoperative variables included hemoglobin levels, neoadjuvant therapy, albumin levels, white blood cell count, lymphocyte count, LWR, neutrophil-lymphocyte ratio, and prognostic nutritional index. RESULTS Of 177 patients, 31.6% (56/177) suffered at least one morbidity, 15.3% (27/177) had multiple morbidities, 7.9% (14/177) suffered severe morbidity. On multivariate analysis, only LWR <0.180 (odds ratio [OR] 2.53, 95% confidence interval [CI] 1.15-5.55) and neoadjuvant therapy (OR 2.49, 95% CI 1.16-5.24) were associated with overall morbidity. For multiple morbidities and severe morbidity, only LWR <0.180 was significantly associated on multivariate analysis with an OR of 2.92 (95% CI 1.19-7.13) and 4.62 (95% CI 1.45-14.73), respectively. CONCLUSIONS LWR is a preoperative marker which can be conveniently applied using standard preoperative blood tests. LWR is an independent risk factor for overall morbidity, multiple morbidities, as well as severe morbidity when used with a cut-off of LWR<1.80.

Abstract
Colorectal cancer (CRC) is one of the most common malignant cancers worldwide. Patients with CRC are diagnosed based on various predictors, including performance status, clinicopathological factors and TNM classification. The aim of the present study was to analyze the neutrophil and lymphocyte counts, as well as the neutrophil-to-lymphocyte ratio (NLR) in pre- and postoperative blood samples of patients with CRC in correlation with specific anatomical variables and disease- free survival (DFS). The variables pre- and postoperative neutrophil count (preNEU and postNEU, respectively), lymphocyte count and NLR were significantly higher in cancer patients than those noted in healthy subjects (all P<0.001). PreNEU count correlated with tumor size, necrosis and tumor budding (R=0.204, P=0.014; R=0.189, P=0.023; R=-0.174, P=0.036, respectively). Moreover, postNEU was associated only with the histological type (R=0.174; P=0.047). The PreLYMPH count was correlated with distant metastasis (R=-0.153, P=0.046). PreNLR and postNLR were associated with the expression of various histological markers of disease progression. Analysis of DFS indicated that the postNEU count in the low group exhibited a tendency to lower DFS duration, although the results were not significant (P=0.055). In conclusion, the present study indicated a significant correlation between the factors analyzed in blood samples of CRC patients and the disease progression markers.

Abstract
BACKGROUND Acute obstructive colorectal cancer requires prompt decompression commonly by emergency surgery (ES). However, self-expanding metal stents (SEMS) have been increasingly used as a bridge-to-surgery (BTS) strategy. MATERIALS AND METHODS In an 8-year period, consecutive patients with acute left-sided colonic obstruction, due to locally advanced colorectal cancer, underwent ES or SEMS implantation. We evaluated technical/clinical success of SEMS, adverse events, and overall (OS) and disease-free survival (DFS) of the two therapeutic options. RESULTS Forty-five patients underwent ES (n = 23) or SEMS (n = 22). The two groups were comparable for sex, age, ASA score and cancer site/stage. Technical and clinical successes of SEMS were 100% and 72.7%, respectively. Clinical success correlated with neutrophil-lymphocyte ratio (NLR) at baseline (OR = 0.65, 95% CI 0.43-0.98, P = .04). SEMS allowed primary anastomosis in the 45.5% of cases (0% in ES). SEMS implantation allowed a higher rate of surgery carried out by a laparoscopic approach: 36.4% vs 13.0% in ES. Performance of a definitive stoma and complications were similar. Median OS (34 in SEMS; 45 in ES, P = .33) and DFS (36 in SEMS; 35 in ES, P = .35) did not differ between the two groups. At univariate analysis, DFS was positively associated with primary anastomosis (HR = 2.44, 95% CI 1.4-16.6, P = .04) and laparoscopic surgery (HR = 8.33, 95% CI 1.08-50, P = .04), and inversely associated with a NLR > 3.6 (HR = 0.59, 95% CI 0.16-0.92, P = .03). At multivariate analysis, no feature retained an independent predictive power. CONCLUSION SEMS is an effective and safe procedure, equivalent to emergency surgery in terms of complications, OS and DFS, providing the chance of a primary anastomosis in the majority of patients.

J Vasc Surg 2020; 72:129-137. [PMID: 32037083 DOI: 10.1016/j.jvs.2019.10.058] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2019] [Accepted: 10/06/2019] [Indexed: 11/19/2022]
Abstract
OBJECTIVE The neutrophil-lymphocyte ratio (NLR) is an inexpensive and useful inflammatory marker that incorporates the balance of the innate (neutrophil) and adaptive (lymphocyte) immune responses. Data exist on the association between NLR and mortality in various coronary diseases and in cancer surgery, but there is a paucity of data on the impact of preoperative NLR on vascular surgical outcomes. The aim of this study was to evaluate the relationship between preoperative NLR and elective endovascular aortic aneurysm repair (EVAR) outcome. METHODS A retrospective review of all patients who underwent elective EVAR at a single institution between 2010 and 2018 was conducted (n = 373). Only patients who had a preoperative complete blood count with differential within 30 days of their operation were included. The NLR was computed by dividing the absolute neutrophil count by the absolute lymphocyte count. A receiver operating characteristic curve was used to determine the optimal cutoff value of NLR with the strongest association with mortality. NLR was dichotomized so that patients with NLR above the threshold were at increased risk of mortality compared with those below it. Continuous variables were analyzed using Wilcoxon nonparametric signed-rank test and categorical variables with the Fisher exact test. A comparison of NLR and mortality was completed using Kaplan-Meier survival analysis. Cox regression analysis was used to evaluate factors associated with mortality through 5-year follow-up. RESULTS Overall, 108 patients were included in this study. An NLR ≥ 4.0 was found to be associated with mortality (P < .0001). Thirty-two patients composed the High-NLR (NLR ≥ 4.0) group and the remaining 76 patients formed the Low-NLR (NLR < 4.0) group. Baseline characteristics were similar between groups, except that the High-NLR group was older (77.9 vs 74.4; P = .047). At a mean of 36.4 months follow-up, the overall mortality rate was 32.4%. Although there were no differences in the perioperative period, the Kaplan-Meier estimates of mortality were significantly greater in the High-NLR group at 1, 2, and 5 years postoperatively (P < .0001). The mean preoperative NLR of the deceased was higher (5.94 ± 5.20; median, 4.75; interquartile range, 3.17-7.83) than those who survived (2.87 ± 1.61; median, 2.53; interquartile range, 1.97-3.49) (P < .0001). Secondary interventions and sac enlargement rates were similar between groups. On univariable analysis, NLR (hazard ratio [HR], 1.17; 95% confidence interval [CI], 1.10-1.23; P < .0001), age (HR, 1.06; 95% CI, 1.02-1.11; P = .004), and aneurysm diameter (HR, 1.04; 95% CI, 1.01-1.07; P = .003) were associated with mortality. On multivariable analysis, NLR (HR, 1.19; 95% CI, 1.12-1.27; P < .0001), age (HR, 1.06; 95% CI, 1.01-1.11; P = .026), and aneurysm diameter (HR, 1.04; 95% CI, 1.02-1.07; P = .003) were associated with mortality. CONCLUSIONS Patients with an elevated preoperative NLR, irrespective of other comorbidities, may represent a previously unrecognized subset of patients who are at heightened risk of mortality after elective EVAR. A complete blood count with differential is an inexpensive test that may be used as a prognostic indicator for outcome after EVAR. Further research is warranted to identify clinical, pathological, or anatomical factors associated with an elevated NLR and to determine modifiable factors, which may help improve long-term survival.

Abstract
BACKGROUND Obstructive colorectal cancer (OCC) is always accompanied by severe complications, and the optimal strategy for patients with OCC remains undetermined. Different from emergency surgery (ES), self-expandable metal stents (SEMS) as a bridge to surgery (BTS), could increase the likelihood of primary anastomosis. However, the stent failure and related complications might give rise to a high recurrence rate. Few studies have focused on the indications for either method, and the relationship between preoperative inflammation indexes and the prognosis of OCC is still underestimated.
AIM To explore the indications for ES and BTS in OCCs based on preoperative inflammation indexes.
METHODS One hundred and twenty-eight patients who underwent ES or BTS from 2008 to 2015 were enrolled. Receiver operating characteristic (ROC) curve analysis was used to define the optimal preoperative inflammation index and its cutoff point. Kaplan–Meier analyses and Cox proportional hazards models were applied to assess the association between the preoperative inflammation indexes and the survival outcomes [overall survival (OS) and disease-free survival (DFS)]. Stratification analysis was performed to identify the subgroups that would benefit from ES or BTS.
RESULTS OS and DFS were comparable between the ES and BTS groups (P > 0.05). ROC curve analysis showed derived neutrophil-to-lymphocyte ratio (dNLR) as the optimal biomarker for the prediction of DFS in ES (P < 0.05). Lymphocyte-to-monocyte ratio (LMR) was recommended for BTS with regard to OS and DFS (P < 0.05). dNLR was related to stoma construction (P = 0.001), pneumonia (P = 0.054), and DFS (P = 0.009) in ES. LMR was closely related to lymph node invasion (LVI) (P = 0.009), OS (P = 0.020), and DFS (P = 0.046) in the BTS group. dNLR was an independent risk factor for ES in both OS (P = 0.032) and DFS (P = 0.016). LMR affected OS (P = 0.053) and DFS (P = 0.052) in the BTS group. LMR could differentiate the OS between the ES and BTS groups (P < 0.05).
CONCLUSION Preoperative dNLR and LMR could predict OS and DFS in patients undergoing ES and BTS, respectively. For OCC, as the potential benefit group, patients with a low LMR might be preferred for BTS via SEMS insertion.

Abstract
OBJECTIVES Intraventricular hemorrhage (IVH) remains a major complication of prematurity, affecting 20-25% of premature infants of very low birth weight. Preterm infants with IVH are at risk for developing significant complications, including posthemorrhagic hydrocephalus and seizures. Multiple studies have reported an association between the neutrophil-to-lymphocyte ratio (NLR) in peripheral blood and outcomes after acute intracranial hemorrhage in adults. However, the prognostic value of the NLR in preterm infants, particularly those with IVH, has not been investigated previously. PATIENTS AND METHODS This retrospective, observational cohort study included premature infants with IVH and a neonatal reservoir placed between January 2013 and January 2018. For each patient, peripheral blood and available cerebrospinal fluid laboratory results within 50 days of IVH diagnosis were averaged. NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count. Differences in NLR levels for patients with seizures or shunt placement were analyzed. RESULTS Data for 13 surviving preterm infants (mean gestational age, 26.5 ± 3.0 weeks) were analyzed. The mean peripheral NLR (n = 13) was 1.6 ± 1.3 for all patients. Patients who experienced seizures had significantly higher peripheral blood NLR (p = 1.2 × 10-6, t-test) than those who did not, and an NLR > 3 correlated with seizure outcomes (p = 0.0035, Fisher's exact). Patients with sepsis or meningitis also had NLR values >3 (p = 0.01 and 0.005, respectively) but there was no correlation between the sepsis/meningitis and seizures patients. No significant correlation was found between NLR and the development of hydrocephalus. CONCLUSION The development of seizures in preterm infants with IVH is known to significantly increase morbidity. In this study, higher peripheral blood NLR (>3) correlated with the development of seizures, independent of sepsis or meningitis. Further prospective validation of the role of NLR as a predictive marker for seizures in preterm infants is warranted.

Abstract
Gut microbiota and blood neutrophil-to-lymphocyte ratio (NLR) are associated with systemic inflammation; however, data on the association between gut microbiota and NLR are lacking. We investigated the association between gut microbiota and NLR. A total of 1,309 subjects who had available data on NLR and 16 S rRNA sequencing of gut microbiota were included in this study. They were grouped according to NLR quartile (Q) as follows: lower Q (n = 328, <25% of NLR range), middle 2Q (n = 653, ≥25% to <75%) and upper Q (n = 328, ≥75%). The diversity and composition of the human gut microbiota in the groups were calculated. The phylogenetic diversity of gut microbiota in the lower group was significantly higher than in the middle 2Q group (P = 0.040). The beta-diversity was significantly different among the three groups (P = 0.043), between the lower and middle 2Q groups (P = 0.029), and between the lower and upper groups (P = 0.026). Bacteroides eggerthii showed a positive correlation with NLR (q = 0.015). The diversity and composition of the gut microbiome were different between the NLR groups. Particularly, patients with a lower NLR had a greater diversity of gut microbiota.
