Objective To explore the application of nutritional and inflammatory markers in the prognosis assessment of resectable pancreatic cancer, and to provide new ideas for the prognosis assessment of patients with pancreatic cancer. Method The recent studies on nutritional and inflammatory markers for prognosis of resectable pancreatic cancer at home and abroad were reviewed. Results Radical pancreaticoduodenectomy was the preferred treatment for patients with resectable pancreatic cancer. Poor nutritional status and severe systemic inflammatory response were closely related to postoperative tumor recurrence and other poor prognosis. Nutritional and inflammatory markers played an important role in evaluating the prognosis of resectable pancreatic cancer. Conclusion Nutritional and inflammatory markers, as simple and economical prognostic indicators, have broad clinical application prospects in the prognostic assessment of resectable pancreatic cancer.
ObjectiveTo determine the predictive value of preoperative systemic immune-inflammatory index (SII) regarding the development of postoperative pulmonary complications (PPCs) after abdominal surgery.MethodsThisretrospective study involved 433 patients undergoing elective abdominal surgery. Logistic regression risk model was used to evaluate the prognostic value of SII. We drew the receiver-operating characteristic (ROC) curve and calculated the area under the ROC curve to compared the predictive ability of SII, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to- lymphocyte ratio (MLR).ResultsThe independent risk factors of PPCs were preoperative respiratory diseases, preoperative history of chronic liver disease, maintenance of intravenous or inhalation anesthesia, and intraoperative infusion of more colloid (P<0.05). However, SII, PLR, NLR, and MLR did not predict the occurrence of PPCs, and they also did not predict ≥3 grade of PPCs (AUC<0.60, P>0.05).ConclusionsPreoperative SII is not a prognostic biomarker of PPCs occurrence in patients undergoing elective abdominal surgery. Other biomarkers, such as PLR, NLR, and MLR, also have no predictive value for the PPCs in these patients.
ObjectiveThis study summarizes the latest research on the use of inflammatory markers to predict clinically relevant postoperative pancreatic fistula (CR-POPF), and explores the impact of perioperative inflammatory regulation on CR-POPF, providing references for early warning and individualized intervention for CR-POPF. MethodsA systematic review and summary of relevant literature from the past decade on the early prediction and diagnosis of CR-POPF using inflammatory biomarkers. ResultsThe inflammatory cascade triggered by pancreatic surgery plays a significant role in the development and progression of pancreatic fistulas. Numerous studies have confirmed that following pancreaticoduodenectomy and distal pancreatectomy, inflammatory markers such as interleukin-6 (IL-6), C-reactive protein (CRP), procalcitonin (PCT), inflammatory cells, and other inflammatory markers have significant predictive and diagnostic value for early CR-POPF. Additionally, studies have shown that dynamic monitoring of the trends and magnitude of changes in these inflammatory markers, as well as the establishment of predictive models incorporating inflammatory indicators, can enhance the accuracy of predicting CR-POPF. Furthermore, appropriate anti-inflammatory therapy during the perioperative period plays a positive role in the prevention and treatment of CR-POPF. ConclusionsEarly prediction of CR-POPF is crucial for improving postoperative clinical outcomes and short-term prognosis in patients. Traditional inflammatory markers such as IL-6, CRP and PCT have unique value in the early prediction and diagnosis of CR-POPF. Dynamic monitoring can reflect changes in disease status, thereby influencing clinical management. Future research should further clarify and standardize the predictive timepoints and threshold criteria for inflammatory markers, and explore novel inflammatory markers to provide more accurate and comprehensive guidance for early risk stratification and personalized management of pancreatic fistula in clinical practice.
Objective This study aims to investigate the changes of inflammatory markers of oropharynx and its correlation with prognosis in the stable phase of chronic obstructive pulmonary disease (COPD). Methods Sixty-two patients with COPD in stable stage were divided into smoking and non-smoking groups, and 31 healthy persons were selected as controls. The pharyngeal swabs were collected to determine tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), collagen type Ⅳ (COL-4), and fibronectin (FN) by an enzyme-linked immunosorbent assay. Meanwhile, eosinophil count and C-reactive protein (CRP) in peripheral blood were measured. The correlations between the above metrics and COPD and the prognosis of the patients were analyzed. Results TNF-α, IL-8, COL-4, FN and CRP levels in patients with COPD were significantly higher compared with control groups (P<0.05), and there were significant differences between smoking and non-smoking groups in inflammatory markers such as TNF-α, IL-8, FN, CRP (P<0.05). The forced expiratory volume in one second (FEV1) and FEV1%pred of patients with COPD were significantly lower than the control group (P<0.05). The smoking index of patients with COPD in smoking group was significantly higher than that in smoking control group (P<0.05). TNF- α and IL-8 were positively associated with blood CRP in patients with COPD. Conclusion The inflammatory markers of oropharynx in patients with COPD are different from those in healthy persons and smoking may promote the increase of inflammatory markers of oropharynx in patients with COPD; the non-invasive detection of paired pharyngeal inflammatory markers may be helpful in determining acute onset and prognosis.
Objective To explore the clinical and inflammatory characteristics and risk factors of severe asthma to improve clinicians' awareness of the disease. Methods The general information of patients with asthma who visited the Department of Respiratory Medicine, the First Hospital of Shanxi Medical University from May 2018 to May 2021, as well as the diagnosis and treatment of asthma, personal history, comorbidities, auxiliary examination, asthma control test (ACT) score were collected. A total of 127 patients were included, including 40 in the severe asthma group and 87 in the mild-to-moderate asthma group. Chi-square test, independent sample t test and logistic regression were used to analyze the clinical characteristics, inflammatory markers and risk factors of severe asthma. Results Compared with the patients with mild to moderate asthma, the patients with severe asthma were more older (51.0±12.0 years vs 40.7±12.8 years, P<0.05), had more smokers (32.5% vs. 14.9%, P<0.05), and more males (67.5% vs. 40.2%, P<0.05). The patients with severe asthma got poor FEV1%pred [(56.1±23.8)% vs. (93.2±18.0)%, P<0.05] and FEV1/FVC [(56.7±13.2)% vs. (75.8±9.0)%, P<0.05)], and more exacerbations in the previous year (2.7±3.1 vs. 0.1±0.4, P<0.05), lower ACT score (14.4±3.7 vs. 18.0±5.0, P<0.05), and higher blood and induced sputum eosinophil counts [(0.54±0.44)×109/L vs. (0.27±0.32)×109/L, P<0.05; (25.9±24.2)% vs. (9.8±17.5)%, P<0.05]. There was no significant difference in the proportion of neutrophils in the induced sputum or FeNO between the two groups (P>0.05). Analysis of related risk factors showed that smoking (OR=2.740, 95%CI 1.053 - 7.130), combined with allergic rhinitis (OR=14.388, 95%CI 1.486 - 139.296) and gastroesophageal reflux (OR=2.514, 95%CI 1.105 - 5.724) were risk factors for severe asthma. Conclusions Compared with patients with mild to moderate asthma, patients with severe asthma are characterized by poor lung function, more exacerbations, and a dominant eosinophil inflammatory phenotype, which is still poorly controlled even with higher level of treatment. Risk factors include smoking, allergic rhinitis, and gastroesophageal reflux, etc.
