Our research was designed to investigate the relationship between systemic immune inflammation (SII) index and allcause, cardiovascular disease (CVD), and cancer-related mortality in patients with CVD. Methods: We used the National Health and Nutrition Examination Survey data from 1999 to 2018 to conduct this study. The association between SII index and all-cause, CVD, and cancer-related mortality in patients with CVD was examined using restricted cubic splines (RCS), Cox proportional hazard models, and subgroup analysis, respectively. CVD was defined as a composite of five outcomes of CVD, including coronary heart disease (CHD), congestive heart failure (CHF), angina pectoris, myocardial infarction, and stroke. Additionally, the link between SII index and all-cause, CVD, and cancer-related mortality in patients with a composite of five outcomes of CVD was also explored. Results: In total, 5329 participants were included. The RCS also showed a U-curve correlation between SII index and the all-cause, CVD, and cancer-related mortality in patients with CVD. As compared with the individuals with lowest quartile of SII index, hazard ratios with 95% confidence intervals for all-cause, CVD, and cancer-related mortality across the quartiles were (1

Background Iron metabolism may be involved in the pathogenesis of the non-alcoholic fatty liver disease (NAFLD). The relationship between iron metabolism and NAFLD has not been clearly established. This study aimed to clarify the relationship between biomarkers of iron metabolism and NAFLD. Methods Based on the National Health and Nutrition Examination Survey (NHANES), restricted cubic spline models and multivariable logistic regression were used to examine the association between iron metabolism [serum iron (SI), serum ferritin (SF), transferrin saturation (TSAT), and soluble transferrin receptor (sTfR)] and the risk for NAFLD. In addition, stratified subgroup analysis was performed for the association between TSAT and NAFLD. Moreover, serum TSAT levels were determined in male mice with NAFLD. The expression of hepcidin and ferroportin, vital regulators of iron metabolism, were analyzed in the livers of mice by quantitative real-time PCR (qRT-PCR) and patients with NAFLD by microarray collected from the GEO data repository. Results Patients with NAFLD showed decreased SI, SF, and TSAT levels and increased STfR levels based on the NHANES. After adjusting for confounding factors, TSAT was significantly negatively correlated with NAFLD. Of note, the relationship between TSAT and NAFLD differed in the four subgroups of age, sex, race, and BMI (P for interaction < 0.05). Consistently, mice with NAFLD exhibited decreased serum TSAT levels. Decreased hepcidin and increased ferroportin gene expression were observed in the livers of patients and mice with NAFLD. Conclusion Serum TSAT levels and hepatic hepcidin expression were decreased in both patients and mice with NAFLD. Among multiple biomarkers of iron metabolism, lower TSAT levels were significantly associated with a higher risk of NAFLD in the U.S. general population. These findings might provide new ideas for the prediction, diagnosis, and mechanistic exploration of NAFLD.

Introduction This study aims to evaluate the efficacy of esketamine on postoperative recovery quality after laparoscopic bariatric surgery. Methods Patients ( n = 74) scheduled for laparoscopic bariatric surgery were randomly divided into two groups: the esketamine group (group E: 0.5 mg/kg/h infusion, i.e., 0.2 mL/kg/h) or the control group (group C: 0.2 mL/kg/h normal saline infusion). The infusions were stopped 20 min before the end of the procedure. The primary outcome was the Quality of Recovery-40 (QoR-40) score on postoperative day 1 (POD 1). The secondary outcomes included QoR-40 scores on PODs 2 and 7, Numeric Rating Scale (NRS) on PODs 1, 2, and 7, time to extubation, additional postoperative analgesic use, length of hospital stay, and time to first exhaust. Additonally, the safety indices were also recorded, including hemodynamic profile, perioperative anesthesia index (Ai), utilization of vasoactive drugs or urapidil, and side effects. Results All in all, 70 of the 74 patients completed the study, 35 in each group. The difference of QoR-40 scores on POD 1 was both statistically and clinically significant [difference 7.21, 95% confidence interval (CI) 5.17, 9.25, p < 0.001]. The difference of QoR-40 on POD 2 was statistically significant but clinically insignificant (difference 4.81, 95% CI 2.69, 6.92, p < 0.001). The difference of NRS scores on POD 1 was statistically significant (difference −1.23, 95% CI −2.36, −0.10, p = 0.033). Compared with group C, group E had a lower utilization rate of phenylephrine and higher Ai values ( p < 0.05). There was no statistical difference between the two groups on other measures. Conclusion Continuous ketamine infusion seems to be safe and well tolerated in laparoscopic bariatric surgery. It improved the quality of postoperative recovery and reduced pain on POD 1. In spite of the increased Ai value during the surgery, it also provided better hemodynamics with less usage of phenylephrine.
