The prognostic value of preoperative neutrophils, platelets, lymphocytes, monocytes and calculated ratios in patients with laryngeal squamous cell cancer

Purpose.: We investigated the association of genetic factors with primary open angle glaucoma (POAG), including high tension glaucoma (HTG) and normal tension glaucoma (NTG), in a Han Chinese population. Methods.: We recruited 1157 POAG cases, including 860 HTG and 297 NTG, and 934 normal controls. A total of 13 previously reported single nucleotide polymorphisms (SNPs) located at four gene regions (TMCO1, CDKN2B-AS1, ATOH7, and SIX1/SIX6) was genotyped. Distributions of allele frequencies were compared between cases and controls as well as in the HTG and NTG subgroups. The IOP, vertical cup-to-disc ratio (VCDR), central corneal thickness (CCT), axial length (AL), and age at diagnosis also were investigated as quantitative phenotypes with genotypes of these SNPs. Results.: The SNPs rs4656461 and rs7555523 at TMCO1, rs523096 and rs2157719 at CDKN2B-AS1, as well as rs33912345 and rs10483727 at SIX1/SIX6 showed statistically significant association with POAG. The SNPs at ATOH7 did not show statistically significant association with POAG in our dataset. In the subgroup analysis of HTG and NTG, multiple variants at CDKN2B-AS1 and SIX1/SIX6 showed stronger association with NTG than HTG. The SNPs rs523096 and rs2157719 at CDKN2B-AS1 as well as rs33912345 and rs10483727 at SIX1/SIX6 were found to be associated with IOP where the minor alleles were associated with an increase in IOP. In contrast, SNPs at TMCO1 showed significant association with HTG only. Conclusions.: Genetic variants in CDKN2B-AS1, SIX1/SIX6, and TMCO1 were associated with POAG in a Han Chinese population. Genes CDKN2B-AS1 and SIX1/SIX6 seem to harbor a tendency toward POAG with lower IOP, while carriers of risk alleles at TMCO1 seem to be predisposed to developing POAG with higher IOP.

Purpose. The aim of this meta-analysis was to clarify the association between the plasma endothelin-1 level and the risks of normal tension glaucoma (NTG) and primary open-angle glaucoma (POAG). Methods. Relevant publications were collected from three databases including PubMed, EMBASE, and the Web of Science through December 31, 2015. In this study, the terms “(endothelin OR ET) AND glaucoma” were searched. Review Manager 5.2 was used to process the data. Results. Seven studies (212 cases, 164 controls) were included for the NTG analysis. The mean plasma endothelin-1 level in the NTG subjects was 0.60 pg/mL (p=0.02, 95% CI: 0.17–1.04) higher than that of the healthy controls. Six studies (160 cases, 174 controls) were included for the POAG analysis, and the endothelin-1 level was 0.63 pg/mL (p=0.007, 95% CI: 0.12–1.15) higher in the POAG subjects than in the healthy controls. Additionally, two studies influenced the meta-analysis results regarding the association of plasma endothelin-1 with POAG by sensitivity analysis, and the probability of publication bias was low. Conclusions. The observation that NTG and POAG subjects showed significantly elevated endothelin-1 plasma concentrations suggests that a higher plasma level of endothelin-1 might increase the risk of NTG and POAG development.

Purpose: We aimed to evaluate whether the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and systemic immune inflammation index (SII) were associated with primary open-angle glaucoma (POAG). Materials and Methods: This retrospective case-control study included 240 patients with POAG and 300 age- and sex-matched control subjects. Complete ophthalmological examination and blood count measurements were performed for all subjects. Results: The values of NLR, PLR, and SII in the POAG group were significantly increased compared with the control group (p < 0.001; p = 0.012; p < 0.001). However, the LMR value was lower in the POAG patients than in the control group (p < 0.001). When we divided the subjects into different age and gender subgroups, the NLR and SII values in the POAG patients were always higher than those in the control group. In the comparison of laboratory parameters in POAG subjects stratified according to severity, we also found that NLR and SII increased with the severity. The receiver operating characteristic (ROC) analysis revealed that the areas under the ROC curve of NLR, PLR, LMR, and SII to predict patients with POAG were found to be 0.627, 0.569, 0.382, and 0.986, respectively. The best cutoff point of NLR was 1.998 with a sensitivity of 59.8% and a specificity of 63.0%, and the SII was 947.365 with a sensitivity of 95.4% and a specificity of 95.7%. Multivariable logistic regression analysis showed that NLR was positively associated with mean deviation; moreover, NLR and SII were independent indicators correlated with POAG (OR 1.502; 95% CI 1.227–1.839; p < 0.001; OR 1.02; 95% CI 1.009–1.021; p < 0.001). Conclusion: We speculated that elevated NLR and SII might serve as readily available inflammatory predictors in POAG patients.
