Clinical analysis and identification of pediatric patients with colonic ulceration

BackgroundA wide variety of diseases mimic inflammatory bowel disease (IBD). This study aimed to reduce the misdiagnosis among children with colonic ulcers.MethodsEighty-six pediatric patients with colonic ulcers detected by colonoscopy were enrolled in the retrospective study. Children were divided into different groups according to the final diagnosis. The clinical characteristics, laboratory examinations, endoscopic findings, and histopathological results were compared.ResultsIBD (n = 37) was just responsible for 43% of patients with colonic ulceration. Other diagnosis included autoimmune diseases (n = 9), infectious enteritis (n = 13), gastrointestinal allergy (n = 8), and other diseases (n = 19). Comparing IBD and non-IBD groups, children with IBD had a higher frequency of symptoms like weight loss/failure to thrive (P < 0.001), perianal lesions (P = 0.001), and oral ulcers (P = 0.022), and higher expression levels of platelet (P = 0.006), neutrophil-to-lymphocyte ratio (NLR) (P = 0.001), erythrocyte sedimentation rate (P < 0.001), C-reactive protein (P < 0.001), Immunoglobulin G (P = 0.012), Interleukin-1β (P = 0.003), Interleukin-6 (P = 0.024) and TNF-α (P = 0.026), and a wider ulcer distribution in the lower gastrointestinal tract (LGIT) (P < 0.001). Expression levels of hemoglobin (P < 0.001) and albumin (P = 0.001) were lower in IBD patients. Multivariate analysis showed hemoglobin, NLR, Score of ulceration in LGIT, and pseudopolyps contributing to the diagnosis of pediatric IBD with colonic ulcers.ConclusionsWe displayed potential indicators to help diagnose pediatric IBD differentiating from other disorders with colonic ulcers more prudently.

Systemic Immune-Inflammation-Based Biomarker and Fragility Fractures in People Living With HIV: A 10-Year Follow-Up Cohort Study in China.

Fragility fractures are a significant concern among people living with HIV(PLWH) due to the combined effects of chronic inflammation, immune dysregulation, and antiretroviral therapy. Traditional biomarkers have limited predictive value for fragility fractures in this population. This study aims to evaluate the systemic immune inflammation-based scores as novel biomarkers for predicting fragility fractures in PLWH in China. We conducted a cohort study of PLWH in the orthopedic department of Beijing Ditan Hospital from January 2011 to September 2023. We monitored fragility fractures and collected data on demographics, clinical characteristics, and laboratory parameters. Multivariate Cox and logistic regression models were used to assess the predictive value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) for fragility fractures. Restricted cubic splines (RCS) were employed to explore potential nonlinear relationships, and subgroup analyses were conducted to examine the stability of these associations. During a median follow-up of 5.5 years, our study included 1148 PLWH patients, and 204 patients (17.8%) experienced fragility fractures. After adjusting for all covariates, SII and SIRI were identified as independent risk factors for fragility fractures in PLWH, whereas NLR, PLR, and MLR were not. Patients with higher levels of SII and SIRI had a significantly increased risk of fragility fractures compared to those with lower levels (HR: 1.96, 95% CI: 1.24-3.10, p = 0.004; HR: 1.83, 95% CI: 1.16-2.88, p = 0.009). RCS analysis indicated a stable linear relationship between SIRI and fragility fractures. Furthermore, KM curves demonstrated that patients with higher SII and SIRI scores had a higher likelihood of experiencing fragility fractures. Our research shows that SII and SIRI are promising biomarkers for predicting fragility fractures in PLWH. Clinicians should consider incorporating SIRI into clinical practice to improve fracture risk stratification and guide preventive strategies for this vulnerable population.

Predictive Factors of Chemotherapy-Induced Peripheral Neuropathy in Breast Cancer: A Decision Tree Model Approach.

Chemotherapy-induced peripheral neuropathy (CIPN) poses a substantial challenge in breast cancer (BC) chemotherapy, affecting the patient's quality of life. Recent studies have focused on exploring predictors and patterns of CIPN occurrence. We aimed to develop a prediction model for CIPN occurrence using a classification and regression tree (CART) algorithm. In this prospective study of 170 patients with BC undergoing chemotherapy, patient-reported adaptation of the Common Terminology Criteria for Adverse Events version 4.0 was used to assess CIPN occurrence. Multivariable analysis using the CART model was tuned using 10-fold cross-validation to identify baseline predictors for CIPN throughout chemotherapy. A receiver operating characteristic curve analysis was conducted for the CART model. A multivariable logistic regression was conducted from the variables included in the CART model to assess the strength and direction of the association. The prevalence of CIPN was 64.7% (n = 110). The most decisive predictor of CIPN occurrence in the CART model was the subject's C-reactive protein (CRP) level. CRP level >3.91 mg/dL, BMI >21.85 kg/m2, and a marital status of unmarried have predicted a probability of 100% in CIPN occurrence. The CART model showed an accuracy of 65.9%, sensitivity of 51.7%, specificity of 73.2%, and an area under the curve of 0.705. A CRP level of >3.91 mg/dL and a neutrophil-to-lymphocyte ratio (NLR) of >2.82 are significantly associated with the occurrence of CIPN (odds ratio [OR], 2.01 [95% CI, 1.01 to 4.01]; P = .046, OR, 2.09 [95%, CI, 1.02 to 4.24]; P = .042, respectively). Baseline CRP, NLR, BMI level, and marital status are significant predictors of CIPN occurrence throughout chemotherapy. Our CART model was better at ruling out individuals who would not experience CIPN. The CART model may provide insight into the future development of individualized patient care and prevention strategies.

Association of innate versus specific immunity with heart failure incidence: a prospective study.

Immune disorders are key heart failure (HF) triggers, but little is known about whether the status of immunity affects the incidence of HF. To explore this, we used blood cell counts and derived ratios to investigate the association between immunity status markers and HF incidence. The number and proportion of peripheral blood leucocytes in a physiological state are related to the body's immune status. Neutrophils, monocytes, SII (systemic immune-inflammatory index), NLR (neutrophil-to-lymphocyte ratio), and PLR (platelet-to-lymphocyte ratio) serve as innate immunity status markers, while lymphocytes and LMR (lymphocyte-to-monocyte ratio) serve as specific immunity status markers. 330 362 UK Biobank (UKB) participants were finally examined. Cox proportional hazard models were used to explore the relationship between immunity status markers and HF incidence. Flexible parametric survival models were used to capture time-varying relationships between blood cell ratios and HRs for HF. Subgroup analyses were conducted by age, sex, and body mass index. Finally, sensitivity analyses were performed to validate the results. During a median follow-up of 14.1 years, 9611 (2.9%) participants developed HF. Neutrophils, monocytes, SII, and NLR were positively associated with HF incidence, with fully adjusted per SD increment HR (95% CI) of 1.20 (1.17 to 1.22), 1.09 (1.07 to 1.12), 1.12 (1.10 to 1.14), and 1.16 (1.14 to 1.18), respectively. Platelets, lymphocytes, and LMR were inversely correlated with HF incidence, with fully adjusted per SD increment HR (95% CI) of 0.97 (0.95 to 1.00), 0.97 (0.95 to 0.99), and 0.90 (0.88 to 0.92), respectively. The innate immunity status markers were positively associated with HF incidence, while specific immunity status markers exhibited an inverse association, offering novel insights for HF prediction and intervention.

Pathogenesis and Biomarkers of Cancer-Related Ischemic Stroke.

To investigate the pathogenesis of cancer-related ischemic stroke (CRIS) and to search for reliable biomarkers of CRIS. Patients with CRIS, only-cancer and only-ischemic stroke who were hospitalized in the First Affiliated Hospital of Guangxi Medical University from May 2022 to January 2024 were recruited, and laboratory and clinical data of the three groups were collected. Peripheral venous blood was collected and enzyme-linked immunosorbent assay (ELISA) was used to detect markers of coagulation (D-dimer) and endothelial integrity (intercellular adhesion molecule-1 (ICAM-1)). The study included 16 patients with CRIS, as well as 16 patients with only-cancer and 16 patients with only-ischemic stroke. Among patients with CRIS, the most common cancer was lung cancer, and the most common pathological type was adenocarcinoma. It was found that compared with patients with only-cancer and only-ischemic stroke, the hemoglobin and lymphocyte percentage in patients with CRIS were decreased (P<0.05), while the neutrophil percentage and neutrophil to lymphocyte ratio (NLR) were increased (P<0.05). Compared with only-ischemic stroke group, the lymphocyte absolute value in patients with CRIS was decreased (P<0.05), and platelet to lymphocyte ratio (PLR), globulin, prothrombin time (PT), international normalized ratio (INR) and ICAM-1 were increased (P<0.05). D-dimer level was higher in patients with CRIS than in only-cancer group (P<0.05). In the present study, the increased NLR, PLR, ICAM-1 and D-dimer were expected to be biomarkers of CRIS, indicating that hypercoagulability mediated by cancer inflammation and endothelial damage may be the pathogenesis of CRIS. The novel findings in the present study will facilitate clinicians to identify the patients at high risk of CRIS. Because of the small sample size, the findings need to be validated by prospective large-sample studies in the future.

Prevalence and Risk Factors of Pulmonary Embolism in COPD Patients Complicated with Secondary Polycythemia.

This study aimed to establish the prevalence of pulmonary embolism (PE) in chronic obstructive pulmonary disease (COPD) patients with secondary polycythemia (SP) and explore the risk factors for PE in COPD patients with SP. We analyzed the prevalence of PE among COPD patients with SP who were hospitalized at Qinghai Provincial People's Hospital between January 2015 and December 2020. From January 2021 to January 2024, we enrolled patients into three groups (COPD+SP+PE, COPD+SP, and control) and performed laboratory measurements, biomarkers, echocardiography, and pulmonary function tests. Patients in the COPD+SP group received clinical treatment, and biomarkers were measured again seven days after treatment. The prevalence of PE in patients with COPD SP was 5.21%. We found that COPD+SP+PE group had significantly higher levels of erythrocyte distribution width (RDW), platelet volume distribution width (PDW), mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), monocyte to large platelet ratio (MLPR), 5-hydroxytryptamine (5-HT), activated protein C (APC), urokinase-type plasminogen activator (u-PA), thrombomodulin (TM), interleukin-38 (IL-38), tissue factor (TF), and fractalkine (FKN) in contrast to COPD+SP group. Biomarkers, such as FKN, β-thromboglobulin (β-TG), APC, u-PA, TM, TF, and IL-38, were risk factors for COPD patients with SP who are complicated by PE. Clinical treatment significantly reduced the levels of β-TG, IL-38, APC, endothelin-1 (ET-1), u-PA, FKN, TM, 5-HT, and neutrophil extracellular traps (NETs) in patients with COPD+SP. PE incidence was significantly higher in patients with COPD and SP. In COPD patients with SP, routine joint detection of blood and cardiac markers, blood gas analysis, and pulmonary function tests can help to identify patients with PE. APC, u-PA, TF, FKN, TM, and IL-38 are risk factors for PE in patients with COPD and SP, and clinical treatment can effectively reduce this risk.

Prognostic Value of Systemic Inflammatory Response in Lymph Node-Negative Colorectal Cancer.

The aim of this study was to investigate the prognostic value of systematic inflammatory response in patients with lymph node-negative colorectal cancer. We retrospectively investigated 245 patients with lymph node-negative colorectal cancer who underwent curative resection and evaluated the prognostic impact of systematic inflammatory response, which was represented by neutrophil-to-lymphocyte ratio (NLR), prognostic nutritional index (PNI), and C-reactive protein-to-albumin ratio (CAR). Then, the prognostic significance of the systematic inflammatory response on survival was analyzed using the Kaplan-Meier method in patients selected by propensity score matching (PSM) analysis. In the multivariate analysis, CAR ≥ .081 (P = .004) was independent predictors of disease-free survival, while American Society of Anesthesiologists physical status ≥3 (P = .049) and CAR ≥ .081 (P < .001) were independent predictors of overall survival. By PSM analysis, PSM-high-CAR was significantly associated with worse disease-free survival (P = .043) and overall survival (P = .041) in patients with lymph node-negative colorectal cancer. C-reactive protein-to-albumin ratio may be a significant indicator of poor long-term outcomes in patients with lymph node-negative colorectal cancer.

Neutrophil Lymphocyte Ratio Predicts Early Neurological Deterioration in Patients with Anterior Circulation Stroke

The clinical significance of the Neutrophil-to-Lymphocyte Ratio as a novel inflammatory biomarker for assessing the severity of intervertebral disc degeneration.

Inflammation is integral to the pathogenesis of intervertebral disc degeneration, yet the role of systemic inflammatory markers in this process remains underexplored. This study aims to explore the association between the Neutrophil-to-Lymphocyte Ratio (NLR) and the severity of disc degeneration. A retrospective analysis was conducted on 375 patients diagnosed with lumbar disc degeneration between April 2018 and May 2021. All patients underwent a complete blood cell count examination. We applied the Pfirrmann grading system for cumulative disc grading, stratifying patients into two groups: a high-score group (cumulative grade > 17) and a low-score group (cumulative grade ≤ 17), based on the median cumulative grade. The association between the NLR and and the severity of disc degeneration was further analyzed using correlation analysis and logistic regression models. Furthermore, the predictive capacity of the NLR for lumbar disc degeneration was assessed using the Receiver Operating Characteristic (ROC) curve. We found a significant positive correlation between high NLR levels and severe disc degeneration. The high-score group exhibited a significantly higher NLR compared to the low-score group [2.63 (1.91-4.18) vs. 2.04 (1.38-2.74), respectively, p < 0.001]. Significant correlations were found between NLR and patient characteristics (including age, BMI, VAS, NSAIDs usage, hemoglobin) and the cumulative grading. Logistic regression analysis identified age and NLR as independent predictors of the severity of disc degeneration. The ROC curve analysis demonstrated a good predictive capability of NLR for lumbar disc degeneration. NLR could serve as a promising biomarker for assessing the severity of lumbar disc degeneration and offer potential benefits in both early diagnosis and treatment strategies.

Elevated hematologic ratios are correlated with acne severity: a national, retrospective cohort study.

Prior studies demonstrated conflicting results regarding hematologic ratios in acne patients. We sought to further characterize hematologic ratios in acne patients, according to demographics and acne severity. National, retrospective cohort study of 122,822 patients using medical records from 2005 to 2024 of patients insured with the largest public healthcare organization in Israel, Clalit Health Maintenance Organization. Moderate-severe acne patients had higher neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) than mild acne patients at diagnosis and 12-18 months before diagnosis. A multivariable regression confirmed the significance of the correlation of increased NLR and PLR with acne severity. Adults and females had higher NLR and PLR than children and males, respectively, at diagnosis, and 12-18 months before diagnosis. Acne severity was significantly associated with elevated NLR and PLR. NLR and PLR may also serve as indicators of upcoming acne severity, as they were elevated 12-18 months before diagnosis. These biomarkers may contribute to the diagnosis, management, and follow-up of patients with acne.

Prognostic values of combined ratios of white blood cells in glioma: a systematic review and meta-analysis.

Gliomas, the most prevalent type of neurological tumor, pose a challenging prognosis for patients. Recent studies have underscored the importance of inflammatory markers such as the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and monocyte/lymphocyte ratio (MLR) in predicting the prognosis of gliomas. We undertook a thorough meta-analysis to elucidate the role of these inflammatory markers in forecasting the prognosis of glioma patients. We extracted hazard ratios (HR) and their corresponding 95% confidence intervals (95% CI) from each study for analysis. To assess heterogeneity and identify influential studies, we conducted sensitivity analysis. Subgroup analysis was performed to investigate sources of heterogeneity, and we employed Egger's test to evaluate publication bias in the meta-analysis. Higher NLR levels were associated with shorter overall survival (HR = 1.46, 95% CI: 1.33-1.60) and progression-free survival (HR = 1.24, 95% CI: 1.04-1.48). There was no significant correlation between PLR levels and overall survival (HR = 1.01, 95% CI: 1.00-1.01) or progression-free survival (HR = 1.00, 95% CI: 0.98-1.02) in glioma patients. Elevated MLR levels were associated with decreased overall survival in glioma patients (HR = 1.78, 95% CI: 1.36-2.34). SII levels did not show any significant association with overall or progression-free survival in glioma patients (HR = 1.00, 95% CI: 0.99-1.01).In the sensitivity analysis, two studies potentially contributed to the instability. Subgroup analyses showed patient population and area were identified as potential sources of heterogeneity. Egger's test showed that there was publication bias in the relationship between NLR and PLR and overall survival (P < 0.05).All randomized controlled models, except for these, were not affected by publication bias. NLR and MLR are two reliable indicators of inflammation in the prognosis of glioma patients; PLR and SII do not have significant value in the prognosis of glioma patients.

Radiomics nomogram combined with clinical factors for predicting pathological complete response in resectable esophageal squamous cell carcinoma.

Predicting the efficacy of neoadjuvant immunochemotherapy (NICT) for esophageal squamous cell carcinoma (ESSC) prior to surgery can minimize unnecessary surgical interventions and facilitate personalized treatment strategies. Our goal is to develop and validate an image-based radiomic model using preoperative computed tomography (CT) scans and clinical data to predict pathological complete response (pCR) in resectable ESSC following neoadjuvant immunotherapy. We retrospectively collected data from patients diagnosed with ESCC at the First Affiliated Hospital of Soochow University between January 2018 and May 2023, who received preoperative neoadjuvant immunochemotherapy. Eligible patients were randomly divided into training and validation sets. Radiomic features extracted from preprocessed CT images were used to develop a radiomic model, incorporating Radiomic score (Rad-score) and clinical factors through multivariate logistic regression analysis. The model's performance was assessed for calibration, discrimination, and clinical utility in an independent validation cohort. We enrolled a total of 105 eligible participants who were randomly divided into two groups: a training set (N=74) and a validation set (N=31). After data dimension reduction and feature selection, we identified 11 radiomic features, which collectively formed the Rad-score. Rad-score had an area under the curve (AUC) of 0.83 (95% CI 0.72-0.93) in the training set and 0.78 (95% CI 0.60-0.95) in the validation set. Multivariate analysis revealed that radiological response and Neutrophil-Lymphocyte Ratio (NLR) were independent predictors of pCR, with p-values of 0.0026 and 0.0414, respectively. We developed and validated a nomogram combining Rad-score and clinical features, achieving AUCs of 0.90 (95% CI 0.82-0.98) in the training set and 0.85 (95% CI 0.70-0.99) in the validation set. The Delong test confirmed the nomogram's superiority over pure radiomic and clinical models. Decision curve analysis (DCA) and integrated discrimination improvement (IDI) assessment supported the clinical value and superiority of the combined model. The nomogram, which integrates Rad-score and clinical features, offers a precise and reliable method for predicting pCR status in ESCC patients who have undergone neoadjuvant immunochemotherapy. This tool aids in tailoring treatment strategies to individual patients.

Factors Affecting Biochemical Recurrence After Radical Prostatectomy and Validity of CAPRA Score in Predicting Biochemical Recurrence

Objective: Biochemical recurrence (BCR) after prostate cancer (PCa) treatment is undesirable. It is important to inform a patient about BCR in preoperative evaluation. We aimed to demonstrate the effectiveness of the (The Prostate Cancer Risk Assessment) CAPRA score used to predict this situation in our study. Material and Methods: The study included 348 patients who underwent Radical Prostatectony (RP) for localized PCa. Demographic, preoperative and postoperative data were collected. CAPRA score based on preoperative total PSA value, Gleason Score, clinical T stage, percentage of positive biopsy cores and age was calculated using these data. BCR was defined as a total PSA value &gt;0.2 ng/dL for two consecutive times after RP. Follow-up periods, recurrence status and time of recurrence were recorded. Results: BCR positivity was detected in 60 (17.2%) of 348 patients. In univariate analyses, PSA level, lesion volume on MRI, ISUP grade, D’Amico risk classification, Seminal vesicule invasion (SVI) and CAPRA score were statistically significant in the groups. In multivariate analyses, PSA level, Neutrophile Lymphocyte Ratio, lesion dimension, intermediate risk according to D’amico classification, Extraprostatic extension (EPE) showed differences between both groups. The probability of biochemical progression-free in CAPRA risk groups shows a significant decrease in the probability of biochemical progression-free in the long term as risk increases in CAPRA risk groups: 91.4% in the low-risk group, 77.8% in the intermediate-risk group and only 61.7% in the high-risk group at 80-month follow-up. Conclusion: CAPRA scoring system should be supported by MpMRI findings and a new nomogram should be developed with these findings.

A Retrospective Analysis of Emergency Versus Elective Surgical Outcomes in Colon Cancer Patients: A Single-Center Study.

Introduction: Emergency surgical interventions for colon cancer are often associated with poorer outcomes compared to elective surgeries due to the advanced state of the disease and the urgency of intervention. This retrospective study aimed to evaluate the management of emergency management of colon cancer and to evaluate differences in patient outcomes. Conducted at a single surgical emergency center, the study analyzed 182 cases, focusing on demographics, tumor characteristics, surgical methods and patient outcomes. Material and Methods: A retrospective observational study was conducted, involving 182 cases who underwent surgery for colon cancer in a single surgical emergency center. Data was collected from hospital records, encompassing demographic details, tumor characteristics, surgical intervention detail and outcomes, alongside with inflammatory profiles. Statistical analyses included descriptive statistics and t-tests with standard significance at p < 0.05. Results: The study showed that emergency cases had significantly poorer in-hospital survival rates (75.42%) compared to elective surgeries. Inflammatory markers such as Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio were higher in emergency cases, suggesting heightened systemic stress. Emergency surgery was also associated with a higher incidence of ostomy and postoperative complications. Conclusions: Emergency surgery for colon cancer is linked to more advanced tumors, increased physiological stress and lesser clinical outcomes. Early detection strategies and active targeted screening could reduce the need for emergency interventions. Future research should focus on early diagnosis protocols and enhancing public health strategies to minimize emergency presentations, thereby leading to better outcomes for colon cancer patients.

Clinical characteristics and prognosis analysis of acute symptomatic seizures secondary to autoimmune encephalitis.

This study aimed to analyze the clinical characteristics and prognosis of patients with autoimmune encephalitis (PWAE) who experienced seizures during the acute phase. Clinical data were collected from 84 patients diagnosed with AE at the General Hospital of Ningxia Medical University between January 2015 and January 2023. Patients were divided into seizure and non-seizure groups. Clinical characteristics of both groups were compared, including differences between anti-NMDAR and anti-LGI1 encephalitis within the seizure group. Due to the limited sample size and to avoid overfitting, we focused on univariate logistic regression analysis to identify individual prognostic factors. A total of 84 patients were enrolled, with 76.19% (64/84) in the seizure group and 23.81% (20/84) in the non-seizure group. The seizure group had a longer hospital stay (p = 0.013), higher rates of impaired consciousness (p = 0.001), and more frequent intensive care unit (ICU) admission (p = 0.011). They also had higher peripheral blood neutrophil-to-lymphocyte ratio (NLR), leukocyte count, and uric acid levels (p = 0.038, p = 0.006, p = 0.020), and were more likely to show slow-wave rhythms on electroencephalography (EEG) (p = 0.031). At 2-year follow-up, there was no significant difference in prognosis between the seizure and non-seizure groups (p = 0.653), with 35.94% (23/64) of the seizure group having a poor prognosis. Status epilepticus (SE), complications, endotracheal intubation, mRS score at discharge, APE2, and RITE2 scores increased the risk of poor prognosis (OR > 1), while intensive care and albumin reduced the risk (OR < 1). Seizures are common in the early stages of AE, with faciobrachial dystonic seizures (FBDS) characteristic of anti-LGI1 encephalitis and SE and super-refractory status epilepticus (Sup-RSE) frequently observed in anti-NMDAR encephalitis. Seizure semiology across AE subtypes lacks specificity, and no symptoms clearly distinguish immune-mediated from non-immune causes. While seizures are linked to AE severity, particularly in anti-NMDAR encephalitis, they do not appear to impact overall prognosis. SE, complications, endotracheal intubation, modified Rankin Scale (mRS) score at discharge, Antibody-Prevalence in Epilepsy and Encephalopathy (APE2) score, Response to Immunotherapy in Epilepsy and Encephalopathy (RITE2) score, intensive care, and albumin were identified as significant prognostic factors.

The association of the perioperative neutrophil-to-lymphocyte ratio with wound healing in patients with Wagner grade 3 and 4 diabetic foot ulcers after tibial cortex transverse transport surgery: a prospective observational cohort study.

Diabetic foot ulcers (DFUs) are severe complications of diabetes, involving multiple etiological factors including neuropathy, vascular insufficiency, and impaired wound healing. The global burden of DFUs is substantial, with significant morbidity and high management costs. Recent advancements have introduced the tibial cortex transverse transport (TTT) technique, which has shown promising results in the management of severe DFUs by promoting angiogenesis and immunomodulation. This prospective cohort study enrolled patients with Wagner grade 3 and 4 DFUs, treated using the TTT technique from May 2022 to September 2023 at MianYang Central Hospital. The study assessed the influence of TTT on the perioperative neutrophil-to-lymphocyte ratio (NLR), an established biomarker of systemic inflammation, and its correlation with wound healing outcomes. A total of 82 patients were enrolled, with 66 completing the study. The survival analysis revealed that patients with a lower preoperative NLR experienced significantly faster wound healing compared with a high NLR (log rank test P< 0.05; hazard ratio (HR) = 0.46; 95% CI: 0.26-0.83). The optimal NLR cutoff values (4.25) were established to predict wound healing times for DFUs. The median NLR was significantly different before TTT surgery, 3 days after TTT surgery, and 1 month after TTT surgery (P<0.05). The TTT technique significantly influences the perioperative NLR and is associated with improved wound healing in DFU patients. The perioperative NLR serves as an effective predictive biomarker for wound healing outcomes, highlighting the significance of interventions targeting NLR values in perioperative management strategies and postoperative monitoring protocols for the treatment of diabetic foot ulcers (DFUs) in clinical practice.
