BACKGROUND Cardiopulmonary bypass (CPB) contributes to the development of systemic inflammatory response after cardiothoracic surgery. As a measure of inflammation and immune reaction, the neutrophil-to-lymphocyte ratio (NLR) has been linked to poor outcomes in a variety of diseases. However, it remains to be seen whether postoperative NLR is associated with CPB patient mortality. The purpose of this research was to explore the prognostic role of the postoperative NLR in adult patients undergoing cardiothoracic surgery with cardiopulmonary bypass. MATERIAL AND METHODS This is an analysis of data stored in the databases of the MIMIC-III, which contains data of critically ill patients for over 50,000. The exposure of interest was postoperative NLR. The primary outcomeaThis study incorporates data from the MIMIC III database, which includes more than 50 000 critically ill patients. The variable of interest was postoperative NLR. The primary outcome was 30-day mortality and the secondary outcomes were 90-day mortality, length of intensive care unit stay, and length of hospital stay. was 30-day mortality, the secondary outcome was 90-day mortality, length of hospital stay and length of ICU stay. RESULTS We enrolled 575 CPB patients. The ROC curve for the postoperative NLR to estimate mortality was 0.741 (95% confidence interval [CI]: 0.636-0.847, P<0.001), and the critical value was 7.48. There was a significant difference between different postoperative NLR levels in the Kaplan-Meier curve (P=0.045). Furthermore, elevated postoperative NLR was associated with increased hospital mortality (hazard ratio [HR]: 1.1, 95% CI: 1.0-1.1, P=0.021). However, there was no important relationship in these patients between the postoperative NLR levels and 90-day mortality (HR: 1.1, 95% CI: 1.0-1.5, P=0.465). CONCLUSIONS Our findings suggest that higher postoperative NLR is associated with greater hospital mortality in adult patients undergoing cardiopulmonary bypass surgery.

Background: Complete blood cell count-based ratios (CBRs), including the neutrophil-lymphocyte ratio (NLR) and monocyte-lymphocyte ratio (MLR), are inflammatory markers associated with postoperative morbidity. Given the link between the surgical stress response and complications after total joint arthroplasty (TJA), this study aimed to evaluate whether higher preoperative CBR values predict greater postoperative benefits associated with dexamethasone utilization.
Methods: The Premier Healthcare Database was queried for adult patients who underwent primary, elective total hip or knee arthroplasty (THA or TKA).

This study aimed to evaluate the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) in patients with peripheral arterial disease (PAD) undergoing femoral endarterectomy. We performed a retrospective analysis of our institutional data, evaluating consecutive patients with PAD who underwent femoral endarterectomy between January 2013 and March 2023. The main objective was to assess the prognostic value of preoperative NLR for 5-year mortality.

Background/objectives: Anastomotic leakage (AL) is one of the most concerning complications following gastrectomy. The aim of this study was to assess and compare the predictive accuracy of C-reactive protein (CRP), procalcitonin (PCT), the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), fibrinogen, and the mean platelet volume (MPV) in the early diagnosis of post-gastrectomy AL.
Methods: A prospective bicentric observational study was conducted including all patients undergoing elective gastrectomy between August 2018 and December 2022.

Background: Hypnosis sedation has recently been used for anesthesia in breast oncologic surgery.
Methods: Between January 2017 and October 2019, 284 patients from our Breast Clinic (Cliniques Universitaires Saint-Luc, Université Catholique de Louvain) and from the Jolimont Hospital were prospectively included in an interventional non-randomized study approved by our two local ethics committees and registered on clinicaltrials.gov (NCT03330117).
