Objective: The aim of this study was to evaluate the prognostic value of both platelet to lymphocyte ratio (PLR) and metabolic syndrome (MetS) in colorectal cancer (CRC) patients.
Patients And Methods: We retrospectively enrolled 1,163 CRC patients. Preoperative values of PLR were stratified into three groups according to cut-off values of 120 and 220. The Kaplan-Meier analysis was used to calculate cumulative survival rate related to PLR and MetS. Cox proportional hazard regression models were used to analyze potential risk factors and the prognosis associated with PLR and MetS in CRC patients.
Results: PLR was significantly higher in the MetS(+) group as compared to MetS(-) group (=0.039). An elevated PLR was significantly associated with mortality (=0.014), but not the existence of MetS (=0.235). In multivariate regression analysis, PLR was an independent risk factor for overall survival (OS) (=0.046). For the subgroup with a PLR >220, MetS was an independent predictor for both OS and disease-free survival (=0.039 and =0.047, respectively) by multivariate analysis adjusting for confounding covariates. In addition, the presence of MetS was associated with a 2-fold increased risk of mortality and tumor recurrences (hazard ratio [HR] =2.0 and HR =1.9, <0.05, respectively).
Conclusion: Preoperative PLR was associated with MetS in CRC patients. Testing for the combined presence of PLR and MetS could potentially improve the predictive accuracy of CRC prognosis.

Introduction: Acute kidney injury involves inflammation and intrinsic renal damage, and is a common complication of severe coronavirus disease 2019 (COVID-19). Baseline chronic kidney disease (CKD) confers an increased mortality risk. We determined the renal long-term outcomes of COVID-19 in patients with baseline CKD, and the risk factors prompting renal replacement therapy (RRT) initiation and mortality.

Objective: To analyse the distribution of pathogens, risk factors and inflammatory indicators related to pelvic infection after hysterectomy.
Methods: Patients who underwent hysterectomy at Women's Hospital of Nanjing Medical University between January 2022 and January 2023 were recruited into this study. Vaginal secretions from patients with suspected postoperative pelvic infection were collected for pathogen cultivation, identification, and antimicrobial susceptibility analysis.
Diagnostic Value of Neutrophil-to-Lymphocyte Ratio (NLR) in Intrahepatic Cholestasis of Pregnancy.

Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse perinatal outcomes, yet the correlation between ICP and the neutrophil-to-lymphocyte ratio (NLR) remains unclear. This study aims to investigate the diagnostic value of NLR in ICP. In this retrospective case-control study, 113 patients with ICP treated in Beilun District People's Hospital from January 2020 to December 2022 were recruited and categorized as the ICP group, and 209 healthy pregnant women treated during the same period were selected as the control group.

Previous studies evaluated the prognostic role of hematological parameters in predicting outcome in patients with infective endocarditis (IE). However, only a few studies evaluated the role of hematological parameters in patients undergoing surgery for IE. The aim of this study was to review our 20-year experience with the treatment of native (NVE) and prosthetic (PVE) valve endocarditis and to evaluate the role of neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-platelet ratio (NPR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), neutrophil-to monocyte ratio (NMR), and systemic inflammatory index (SII) on early and long-term outcomes of patients undergoing surgery for NVE and PVE.

This study aims to evaluate the prognostic significance of various laboratory parameters in predicting the length of hospital stay and mortality among pediatric patients undergoing lobectomy and pneumonectomy for infectious or noninfectious diseases. This study was conducted by retrospective data analysis of 59 pediatric patients who underwent lobectomy and pneumonectomy due to variable diseases at the department of chest surgery. Pediatric patients diagnosed with variable diseases and who underwent lobectomy or pneumonectomy, patients who were hospitalized during the study period and underwent surgical intervention, and patients who had at least one laboratory parameter recorded before surgery were included in the study.
