Background: Obstructive sleep apnea (OSA) is increasingly recognized as a systemic disorder associated with insulin resistance and elevated risk of type 2 diabetes. While continuous positive airway pressure (CPAP) is the standard therapy, its long-term metabolic benefits remain inconsistent. The metabolic impact of upper airway surgery is less well defined. Methods: In this retrospective study, 49 patients with polysomnography-confirmed OSA who underwent upper airway surgery were evaluated. Respiratory and metabolic parameters—including apnea–hypopnea index (AHI), fasting plasma glucose, fasting insulin, glycated hemoglobin (HbA1c), and homeostatic model assessment for insulin resistance (HOMA-IR)—were assessed preoperatively and at 6 months postoperatively. Associations between changes in AHI (ΔAHI) and insulin resistance (ΔHOMA-IR) were analyzed using correlation and receiver operating characteristic (ROC) analyses. Results: Significant improvements were observed in both respiratory and metabolic parameters. AHI decreased from 46.6 ± 25.8 to 20.7 ± 14.1 events/h (p < 0.001). Fasting plasma glucose, insulin levels, and HOMA-IR were significantly reduced postoperatively (all p < 0.05), while HbA1c showed a downward trend. Reduction in AHI was moderately correlated with improvement in insulin resistance (r = 0.527, p < 0.001). ROC analysis demonstrated modest discriminative ability of ΔAHI for identifying normalization of insulin resistance (AUC = 0.62). Conclusions: Upper airway surgery was associated with significant improvements in insulin resistance and glycemic parameters in patients with OSA. The correlation between airway improvement and metabolic change supports a physiological link between upper airway obstruction and insulin sensitivity. These findings suggest that upper airway surgery may represent a clinically relevant adjunct within multimodal strategies for metabolic risk reduction, particularly in patients unable to tolerate CPAP therapy.

Background: Postoperative hyperbilirubinemia is a serious complication after cardiac surgery and has been associated with increased perioperative morbidity and mortality. However, data specifically addressing patients undergoing redo valve surgery remain limited. This study aimed to determine the incidence and risk factors of postoperative hyperbilirubinemia after redo valve surgery, and evaluate its association with early postoperative outcomes. Methods: We retrospectively reviewed 259 adult patients who underwent elective redo valve surgery under cardiopulmonary bypass (CPB) between March 2018 and July 2024. Postoperative hyperbilirubinemia was defined as a serum total bilirubin level > 3 mg/dL at any time after surgery. Patients were divided into a hyperbilirubinemia group and a non-hyperbilirubinemia group. Perioperative variables were compared between groups. Univariable and multivariable logistic regression analyses were performed to identify risk factors for postoperative hyperbilirubinemia. Postoperative complications and in-hospital mortality were also compared. Results: Postoperative hyperbilirubinemia occurred in 101 of 259 patients (39.0%). Compared with patients without hyperbilirubinemia, those with hyperbilirubinemia had longer mechanical ventilation and intensive care unit stay, and higher rates of pneumonia, reintubation, tracheostomy, continuous renal replacement therapy, and in-hospital mortality. Univariable logistic regression showed that higher EuroSCORE II, higher preoperative total bilirubin and direct bilirubin levels, lower hemoglobin and platelet count, pulmonary hypertension, anemia, longer operative time, CPB duration, and aortic cross-clamp time, lower nasopharyngeal temperature, greater intraoperative blood loss, larger red blood cell and plasma transfusion volumes, and concomitant surgery on all three valves were associated with postoperative hyperbilirubinemia. Multivariable analysis identified elevated preoperative direct bilirubin, prolonged CPB duration, and more plasma transfusion as independent risk factors. Receiver operating characteristic analysis showed that peak postoperative total bilirubin had moderate prognostic discrimination for in-hospital mortality, with an optimal cut-off value of 3.95 mg/dL (AUC 0.756, sensitivity 66.7%, specificity 80.2%, p = 0.003). Conclusions: Postoperative hyperbilirubinemia is common after redo valve surgery and is associated with worse early postoperative outcomes and higher in-hospital mortality. In this setting, postoperative bilirubin elevation should be interpreted primarily as a prognostic marker of perioperative stress and hepatic vulnerability rather than a direct causal driver of adverse outcomes. Elevated preoperative direct bilirubin, prolonged CPB duration, and greater plasma transfusion were independently associated with the development of postoperative hyperbilirubinemia in this high-risk population.

Objective: Serum albumin/creatinine ratio (sACR) integrates nutritional–inflammatory status and renal reserve. We evaluated its ability to predict 1-year reintervention for symptomatic graft occlusion in patients undergoing prosthetic above-knee femoropopliteal bypass for peripheral artery disease (PAD). Methods: This single-center retrospective study included 132 adults (7 women, 125 men) who underwent Dacron above-knee femoropopliteal bypass. The primary analysis evaluated preoperative sACR as a continuous variable. For descriptive comparisons and Kaplan–Meier visualization, patients were stratified according to the median preoperative sACR value (3.77), yielding two groups: <3.77 vs. ≥3.77. The primary endpoint was reintervention for symptomatic graft occlusion confirmed by imaging. Discrimination was assessed using ROC analysis, and the ROC-derived cutoff was interpreted as an exploratory threshold rather than a validated clinical decision point. Associations with 1-year reintervention were assessed using Cox proportional hazards regression analysis (age, diabetes, hypertension, smoking, coronary artery disease, hemodialysis-dependent chronic kidney disease, hemoglobin level, GFR, total protein level, antiplatelet use, and anticoagulant use). Results: Most baseline characteristics were comparable between groups; however, hemodialysis-dependent chronic kidney disease was more frequent in the low-sACR group. Reintervention occurred significantly more often in the low-sACR group from month 1 onward. sACR significantly discriminated 1-year events (AUC = 0.736; p < 0.001). The optimal cutoff was ≤3.7 (sensitivity 90.9%, specificity 64.6%). Higher sACR was associated with lower 1-year event risk in both univariate and multivariate models (adjusted HR 0.61, 95% CI 0.43–0.87; p = 0.007). Conclusions: Preoperative sACR is a practical biomarker associated with early and 1-year reintervention risk after prosthetic above-knee femoropopliteal bypass and may aid perioperative risk stratification.

Background and Objectives: Preoperative anaemia represents a key modifiable risk factor in obstetrics. Within the framework of Patient Blood Management (PBM), establishing precise hemoglobin (Hb) thresholds is essential for optimal clinical decision-making. This study aimed to assess the predictive value of preoperative hemoglobin levels and to determine the optimal cutoff associated with transfusion risk. Materials and Methods: A retrospective analysis was performed on 932 pregnant women. The association between preoperative hemoglobin, anticoagulant therapy, mode of delivery and maternal age with the need for red blood cell transfusion was evaluated using binary logistic regression and Receiver Operating Characteristic (ROC) curve analysis with the Youden index. Results: Red blood cell transfusion was required in 5.2% (n = 48) of the study population. Logistic regression identified preoperative hemoglobin as the strongest independent predictor (p < 0.001, OR = 0.216, 95% CI: 0.153–0.306), indicating that each 1 g/dL increase in Hb reduced the likelihood of transfusion by 78.4%. Anticoagulant therapy and age were not significant independent predictors (p > 0.05). ROC analysis demonstrated excellent predictive performance, with an Area Under the Curve (AUC) of 0.875 (95% CI: 0.823–0.927, p < 0.001). The optimal threshold for predicting transfusion risk was 10.9 g/dL (sensitivity: 89.6%, specificity: 60.5%). Conclusions: Preoperative hemoglobin concentration is the primary determinant of transfusion risk, outweighing the influence of clinical comorbidities. The integration of PBM protocols designed to sustain hemoglobin levels above 10.9 g/dL is essential to reduce perioperative transfusion requirements and to promote improved maternal safety and clinical outcomes.

Background: Wilms tumor (WT) rupture is a serious complication that upstages the disease and requires treatment intensification. This study evaluates clinical characteristics, radiological-pathological concordance, and survival outcomes of ruptured versus non-ruptured WT at a major Middle Eastern tertiary center. Methods: We conducted a retrospective cohort study of 111 pediatric patients with unilateral WT treated at King Hussein Cancer Center, Jordan, between October 2014 and December 2023 (follow-up to December 2025). Tumor rupture was defined by preoperative CT findings (peritumoral effusion, hemorrhage, or peritoneal nodules), intraoperative capsular breach/spillage, or pathological confirmation. Event-free survival (EFS) and overall survival (OS) were estimated using Kaplan–Meier methods and compared with the log-rank test. Multivariable Cox regression identified independent prognostic factors. Results: Tumor rupture occurred in 17 patients (15.3%). Ruptured cases were older (median 4.2 vs. 3.5 years, p = 0.03), had larger tumors (13.7 vs. 11.7 cm, p = 0.01), and presented with lower hemoglobin (7.9 vs. 10.4 g/dL, p < 0.001). All ruptured cases were stage III/IV, with 41% having distant metastases at diagnosis. Five-year EFS was 44.1% vs. 75.8% (p = 0.025) and OS was 58.2% vs. 81.4% (p = 0.002) for ruptured vs. non-ruptured groups. On multivariable analysis, rupture independently predicted death (HR 17.62, 95% CI 2.69–115.48, p = 0.003) and relapse (HR 8.1, 95% CI 1.66–39.57, p = 0.01). Conclusion: WT rupture is associated with advanced disease at presentation and significantly inferior survival. Substantial discordance between preoperative radiological/intraoperative findings and post-chemotherapy pathology highlights the “masking effect” of neoadjuvant chemotherapy. A multidisciplinary approach integrating initial imaging, surgical notes, and histology is essential to avoid undertreatment in SIOP-based protocols. Full article

Background/Objectives: Early childhood caries (ECC) is a chronic inflammatory condition that may impose a systemic burden in pediatric patients. This study aimed to evaluate the association between dental caries severity, classified by dmft (decayed, missing, and filled teeth for primary dentition) scores, and preoperative systemic inflammatory markers derived from routine complete blood counts (CBC). Methods: This retrospective study included 159 children aged 36–71 months. Participants were categorized into three groups based on dmft scores: low (0–3), medium (4–8), and high (≥9). Hematological parameters and inflammatory indices, including neutrophil-to-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII), were analyzed using one-way ANOVA with post hoc comparisons. Results: Significant differences were observed among dmft groups for neutrophil and lymphocyte percentages (p = 0.026 and p = 0.027) and lymphocyte count (p = 0.020). The medium severity group demonstrated higher neutrophil levels and lower lymphocyte values compared to the high severity group (p < 0.05). Although overall group differences for NLR and SII were not statistically significant (p > 0.05), both markers were significantly higher in the medium group than in the high group (p < 0.05). No significant differences were found in hemoglobin, RDW, or platelet parameters. Conclusions: A non-linear trend was observed, with relatively elevated inflammatory markers in the moderate dmft group. These findings suggest that systemic inflammation in ECC is more closely related to disease characteristics than to caries burden alone. CBC-derived parameters may provide supportive but limited value for assessing systemic inflammatory status in pediatric dental patients. Full article

Background and Objectives: Patient blood management (PBM) strategies are effective in reducing transfusion requirements and improving perioperative outcomes in total hip arthroplasty (THA) and total knee arthroplasty (TKA). The SARS-CoV-2 pandemic profoundly disrupted hospital organization and limited the application of established PBM protocols. This study assessed the impact of COVID-19-related organizational disruption on PBM implementation and perioperative outcomes in primary total hip and knee arthroplasty. Materials and Methods: This monocentric retrospective study included consecutive patients undergoing primary unilateral THA or TKA between January 2019 and February 2023. Patients were stratified into three periods: pre-COVID-19, during COVID-19, and post-COVID-19. Primary outcomes included transfusion rate, allocated RBC units, PRM transfer, hospital length of stay, and postoperative day-4 hemoglobin levels. Secondary outcomes were factors associated with postoperative day-4 hemoglobin and PRM admission. Results: A total of 5789 patients were included: 1889 in the pre-COVID-19 period, 1416 during COVID-19, and 2484 post-COVID-19. Despite reduced PBM implementation during the COVID-19 period, postoperative Hb levels and transfusion rates remained stable across groups. The number of allocated red blood cell units increased without a corresponding rise in transfusion rates, suggesting a precautionary allocation strategy. A descriptive reduction in median length of stay was observed in the post-COVID-19 phase. A significant decrease in the proportion of patients transferred to Physical and Rehabilitation Medicine departments during the COVID-19 and in the post-COVID-19 period was observed. Multivariable analysis identified age, BMI, preoperative Hb, sex, procedure type, IVFCM administration, and transfusion as predictors of postoperative day-4 Hb, while age, IVFCM administration, transfusion, procedure type, and study period were associated with PRM admission. Conclusions: Despite major organizational disruption, perioperative hemoglobin levels and transfusion rates remained stable, while hospital length of stay decreased. These findings may partly reflect strict selection of already optimized patients; however, this strategy is not equivalent to structured PBM and cannot be generalized to an unselected arthroplasty population.

Background: Osteoporotic vertebral compression fractures (OVCFs) are among the most 11 common fragility fractures in the elderly. Although vertebroplasty and kyphoplasty provide effective pain relief, new vertebral fractures remain a significant concern postoperatively. Imaging parameters associated with sarcopenia and systemic inflammatory markers have been individually associated with fracture risk, but their combined predictive value in the postoperative period has not been adequately defined. Methods: This retrospective cohort study included 166 patients who underwent vertebroplasty or kyphoplasty for OVCFs with a follow-up period of at least 12 months. Cross-sectional area (CSA) and density (HU) of the Psoas muscle were measured at the L3 mid vertebral level on preoperative CT. Preoperative hematological indices (NLR, PLR, LMR, SII, lymphocyte count, hemoglobin, and MPV) were recorded. The primary outcome was the development of a new vertebral fracture. Group comparisons were performed using Mann–Whitney U tests with Benjamini–Hochberg correction. Logistic regression identified independent predictors. Internal validation was performed using bootstrap optimism correction (1000 iterations) and 10-fold cross-validation. Calibration was assessed using the Hosmer–Lemeshow test and calibration plots. Results: Forty-nine patients (29.5%) developed a new fracture. After multiple comparison correction, Psoas 25 HU (BH-adj p < 0.001, r_rb = −0.810), Psoas CSA (BH-adj p < 0.001, r_rb = −0.622), NLR (BH-adj p = 0.016), lymphocyte count (BH-adj p = 0.009), and hemoglobin (BH-adj p = 0.033) showed significant differences between groups. SII did not remain significant after multiple-comparison correction (BH-adjusted p = 0.092). In multivariate logistic regression, only Psoas CSA (OR = 0.403, 95% CI 0.230–0.708, p = 0.002) and Psoas HU (OR = 0.825, 95% CI 0.770–0.885, p < 0.001) remained independently significant. The parsimonious model, with adequate calibration (Hosmer–Lemeshow p = 0.524), achieved an optimism-adjusted AUC of 0.918 (10-fold CV AUC = 0.924). A Psoas HU threshold of 20.50 yielded 79.6% sensitivity and 94.9% specificity. Conclusions: CT-derived Psoas muscle mass and quality are strongly associated with new vertebral fractures after percutaneous vertebral augmentation procedures in this retrospective cohort and showed stronger independent predictive performance than systemic inflammatory markers. These readily accessible imaging biomarkers can aid in risk stratification, although the proposed threshold requires externally validation before clinical implementation. Full article

Background and Objectives: The therapeutic role of surgery in Crohn’s disease has evolved in the era of advanced biologic therapies, particularly in patients with complex and treatment-refractory disease. This study aimed to evaluate the relationship between preoperative biologic exposure and surgical outcomes, with a focus on predictors of more extensive surgical procedures, postoperative biological response, and postoperative biologic management. Materials and Methods: We conducted a retrospective cohort study including 60 patients with Crohn’s disease who underwent CD-related surgical interventions between January 2011 and December 2024. Clinical, surgical, and therapeutic data were collected. Combined resection procedures were defined as intestinal resections associated with additional surgical interventions. Postoperative biological response was defined as an exploratory composite endpoint reflecting the simultaneous normalization of hemoglobin, serum albumin, and C-reactive protein at six months. Statistical analyses, including univariable and multivariable methods, were performed. Results: Combined resection procedures were associated with advanced disease, particularly penetrating phenotypes and intra-abdominal sepsis, and with more frequent postoperative biologic intensification (OR 5.56, 95% CI: 1.05–29.57, p = 0.044). Postoperative biologic management included maintenance and intensification strategies (initiation or switching of biologic therapy). At six months, postoperative biological response was achieved in 20.7% of patients (12/58). No significant associations were observed between biological response and preoperative anti-TNF exposure or postoperative biologic intensification. Despite the relatively low rate of complete biological normalization, hemoglobin and albumin normalization were observed in 79.3% and 69.0% of patients, respectively, while the median fecal calprotectin decreased from 820 µg/g preoperatively to 130 µg/g at follow-up. Endoscopic remission was observed in 47.6% of patients with available SES-CD assessment. Conclusions: In patients with complex Crohn’s disease, surgical intervention remains an essential component of multidisciplinary management. While complete postoperative biological normalization was achieved in a limited proportion of patients, surgery was associated with consistent improvements in inflammatory and nutritional parameters. Further prospective studies are needed to better define predictors of postoperative recovery and to clarify the role of surgery within modern treatment algorithms. Full article

Background: The very-low-calorie ketogenic diet (VLCKD) is increasingly used before bariatric surgery (BS), but its effects on surgical and long-term outcomes remain unclear. Objective: The aim of this study was to compare the impact of a 4-week VLCKD with a 4-week low-calorie diet (LCD) on preoperative, perioperative and postoperative outcomes for up 12 months in patients undergoing BS. Methods: In this prospective study, 72 (n = 36: VLCKD; n = 36: LCD) patients (mean age 43.2 ± 10.6 years; BMI 45.6 ± 6.4 kg/m²; 87.5% female) submitted to sleeve gastrectomy were enrolled at a tertiary care center from 2022 to 2024. Results: No adverse events were detected with both diets. The VLCKD was associated with a greater preoperative median weight loss percentage (−5.5 vs. −2.6 kg, p < 0.001), BMI reduction (−2.6 vs. −1.2 kg/m², p < 0.001), shorter hospital stay (3.0 ± 0.2 vs. 3.4 ± 0.9 days, p = 0.017), higher day-1 postoperative hemoglobin (12.7 ± 1.3 vs. 12.0 ± 1.2 g/dL, p = 0.024), and lower day-1 postoperative median C-reactive protein levels (9.7 vs. 13.4 mg/L, p = 0.042). These associations were confirmed in a multiple regression model, after adjustments for BMI at enrolment, age and sex. After 6 months, the VLCKD was associated with greater reductions in mean weight loss percentage (−24.9 ± 7.8 vs. −19.6 ± 9.4 kg, p = 0.012), BMI reduction (−11.7 ± 4.4 vs. −8.7 ± 3.9 kg/m², p = 0.003), neck circumference (−4.9 vs. −3.6 cm, p = 0.027) and lower aminotransferase levels. At 12 months, VLCKD patients maintained significant advantages over the same variables, except for neck circumference. Conclusions: A short preoperative VLCKD was safe and was associated with greater short-term weight reduction compared with the LCD, with potential benefits extending to early postoperative recovery and 1-year outcomes.

Purpose: This retrospective study aimed to identify factors associated with postoperative cognitive dysfunction (POCD) in patients undergoing hepatectomy, with particular attention to liver disease-related characteristics and perioperative variables. A secondary aim was to develop a clinically applicable nomogram for individualized risk estimation in this population. Patients and Methods: A retrospective cohort study was conducted in 314 consecutive patients who underwent hepatectomy at Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School between January 2023 and December 2024. Patients were included if they had complete clinical data and underwent preoperative and postoperative cognitive assessment. Exclusion criteria included preoperative cognitive impairment (Montreal Cognitive Assessment [MoCA] score < 26), preexisting neurological or psychiatric disorders, and in-hospital death within 72 h after surgery. POCD was defined as a decline of ≥3 points in the MoCA score from baseline to postoperative day 5. Clinical, surgical, nutritional, and perioperative variables were analyzed, and a nomogram was constructed based on the final multivariable logistic regression model. Results: The overall incidence of POCD was 27.4% (86/314). The final multivariable model included sarcopenia, preoperative hemoglobin < 120 g/L, Child–Pugh classification, alcohol consumption, operative duration, and pain score on postoperative day 1. The nomogram incorporating these variables showed good discriminative ability, with an area under the curve of 0.87 (95% CI: 0.83–0.92). Conclusions: In this retrospective cohort of patients undergoing hepatectomy, several perioperative clinical factors were associated with POCD. The proposed nomogram may serve as a practical tool for perioperative risk estimation and support more individualized management in higher-risk patients. Full article

Background and Objectives: Craniosynostosis repair is associated with a high perioperative transfusion rate, but preoperative prediction models remain limited. This exploratory study aimed to develop and internally validate clinically prespecified preoperative models for predicting intraoperative red blood cell transfusion in pediatric craniosynostosis surgery and to evaluate whether adding fused suture extent improved model performance. Materials and Methods: This retrospective single-center prediction model study included children who underwent craniosynostosis repair between 2014 and February 2026. Patients undergoing repeat procedures or concurrent surgery for other craniofacial anomalies were excluded. The outcome was any intraoperative red blood cell transfusion. Candidate predictors were prespecified as age, weight, American Society of Anesthesiologists Physical Status (ASA-PS), preoperative hemoglobin, preoperative platelet, and fused suture extent. Five paired baseline/full ridge-penalized logistic regression models were developed, with fused suture extent added only to the full models. Performance was evaluated using apparent and bootstrap optimism-corrected area under the receiver operating characteristic curve (AUC) and Brier score. Results: Twenty-one patients were included, and nine (42.9%) received intraoperative transfusion. Across all five comparisons, inclusion of fused suture extent improved optimism-corrected discrimination and reduced prediction error. Corrected AUC increased from 0.470 to 0.674, from 0.475 to 0.738, from 0.552 to 0.667, from 0.516 to 0.704, and from 0.466 to 0.694 across the five model pairs. The best-performing model included weight, preoperative hemoglobin, ASA-PS, and fused suture extent, with an optimism-corrected AUC of 0.738 and an optimism-corrected Brier score of 0.242. Conclusions: Inclusion of fused suture extent improved preoperative prediction of intraoperative transfusion and may support perioperative blood management planning in pediatric craniosynostosis surgery. However, external validation using larger independent cohorts is necessary prior to clinical implementation. Full article

Background: Chronic hypoxemia in cyanotic congenital heart disease triggers well-recognized hematological adaptation; however, whether hypoxemia also drives systemic inflammatory activation remains uncertain. This study aimed to evaluate hematological parameters and inflammatory indices in cyanotic and acyanotic congenital heart disease (CHD) to better characterize the relationship between hypoxemia and systemic inflammatory status. Methods: In this single-center retrospective study, 260 children with congenital heart disease were classified as cyanotic (n = 158) or acyanotic (n = 102). Preoperative clinical data and laboratory parameters were analyzed, including oxygen saturation, hemoglobin, hematocrit, leukocyte indices, C-reactive protein (CRP), and procalcitonin (PCT). Inflammatory indices derived from complete blood counts were calculated, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune–inflammation index (SII). Results: Oxygen saturation was significantly lower in cyanotic patients than in acyanotic patients (75 ± 9% vs. 95 ± 4%, p < 0.001). Consistent with hypoxemia-driven hematological adaptation, hemoglobin and hematocrit levels were significantly higher in the cyanotic group (16.1 ± 2.9 g/dL vs. 13.1 ± 2.0 g/dL and 50.8 ± 9.7% vs. 39.7 ± 5.5%, respectively; p < 0.001). In contrast, inflammatory indices (NLR, PLR, and SII) were similar between cyanotic and acyanotic patients, and no significant associations were observed between oxygen saturation and these inflammatory indices. Conclusions: While cyanotic congenital heart disease demonstrates marked hematological adaptation secondary to chronic hypoxemia, systemic inflammatory indices appear similar in cyanotic and acyanotic patients. These findings suggest a relative dissociation between hypoxemia-driven hematological responses and the evaluated systemic inflammatory indices, indicating that inflammatory burden in congenital heart disease may not be solely explained by cyanosis and may reflect additional underlying mechanisms not captured by these markers.

Objectives: Soft tissue sarcomas (STS) are biologically heterogeneous malignancies with unpredictable clinical behavior. Although tumor size, histological grade, and surgical margin status remain the main determinants of prognosis, additional biomarkers that integrate tumor biology and host-related factors are needed. The hemoglobin × albumin × lymphocyte/platelet (HALP) score reflects systemic inflammation and nutritional status. This study aimed to evaluate the association between preoperative HALP score and oncological as well as surgical outcomes in patients undergoing curative resection for STS. Materials and Methods: A retrospective cohort study was conducted including 46 consecutive patients who underwent surgery for STS between 2017 and 2025. HALP scores were calculated using preoperative laboratory parameters, and patients were stratified into low- and high-HALP groups according to the cohort median (24.9). Overall survival (OAS) and disease-free survival (DFS) were analyzed using the Kaplan–Meier method and Cox proportional hazards models. Surgical margin status and postoperative complications were also compared. Results: Patients with low HALP scores had significantly larger tumors, higher rates of non-R0 resection, and increased major complications (p < 0.05). Recurrence and mortality were more frequent in the low-HALP group. Kaplan–Meier analysis demonstrated significantly shorter OAS (log-rank p = 0.0034) and DFS (log-rank p = 0.0318) in patients with low HALP scores. In univariate Cox analysis, HALP was significantly associated with survival outcomes; however, in multivariate analysis, histological grade and surgical margin status remained independent prognostic factors, while HALP lost independent significance. Conclusions: A low preoperative HALP score is associated with aggressive tumor characteristics, increased surgical morbidity, and poorer survival in STS patients. Although HALP did not retain independent significance in multivariable analysis, its strong association with tumor aggressiveness and survival suggests that it may reflect the systemic manifestation of high-risk tumor biology. As a simple and cost-effective biomarker derived from routine laboratory parameters, HALP may support preoperative risk stratification and help identify patients with biologically aggressive disease.

Objective: To evaluate the prognostic utility of the five-item modified Frailty Index (mFI-5) for postoperative outcomes in older adults undergoing posterior lumbar interbody fusion (PLIF) for degenerative lumbar disease and to develop an interpretable preoperative risk model for medical complications (CxME). Methods: We retrospectively reviewed consecutive patients aged ≥65 years who underwent PLIF for lumbar spondylosis at a single tertiary institution. Baseline demographics, comorbidities, symptoms, American Society of Anesthesiologists (ASA) physical status, bone mineral density, antithrombotic use, perioperative laboratory findings, and operative variables were collected. CxME were defined as Clavien–Dindo grade ≥ II complications occurring during index hospitalization or within 30 days postoperatively. mFI-5 was calculated from five preoperative variables and stratified as 0, 1, and ≥2. Multivariable logistic regression was used to identify independent predictors of CxME. Results: Among 255 patients (mean age 72.6 years), 53 (20.8%) developed CxME. Patients with CxME were older and had higher rates of diabetes mellitus and preoperative dependency. mFI-5 ≥ 2 was more frequent in patients with CxME than in those without (66.0% vs. 27.3%, p < 0.001). Higher frailty was associated with older age, greater comorbidity burden, higher ASA class, lower preoperative hemoglobin, greater transfusion exposure, longer hospital stay, and a higher incidence of CxME (14.0%, 9.6%, and 38.9% for mFI-5 scores 0, 1, and ≥2, respectively; p < 0.001). In multivariable analysis, age (OR 1.133, 95% CI 1.055–1.216; p < 0.001) and mFI-5 (OR 2.103, 95% CI 1.387–3.188; p < 0.001) independently predicted CxME. The Age + mFI-5 model showed fair discrimination (optimism-corrected area under ROC 0.734). Conclusions: Preoperative frailty and age independently predicted postoperative medical complications after PLIF in older adults. The Age + mFI-5 model may support risk stratification, counselling, and perioperative optimization. Full article
