Although imaging like X-ray and computed tomography (CT) aids diagnosis, cost-effective hematological biomarkers are still needed. This study evaluates the diagnostic values of hematological biomarkers for detecting complications, determining the need for surgery, and predicting prognosis in patients with bowel obstruction.METHODSA systematic review and meta-analysis was conducted following PRISMA guidelines. We systematically searched Web of Science, PubMed, Scopus, Embase and Cochrane Library for studies published up to June 2025. Inclusion criteria encompassed observational or case-control studies reporting sensitivity/specificity of neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), D-dimer, or lactate in bowel obstruction outcomes. Data extraction included true/false, positives/negatives, cutoff values, and receiver operating characteristic (ROC) parameters. Bivariate models pooled sensitivity/specificity, while summary ROC curves and Youden index determined optimal thresholds.RESULTSThis study included 34 articles comprising a total of 5871 patients. CRP at a cutoff of 26.91 mg/L (Youden index: 0.97) for diagnosing bowel ischemia showed pooled sensitivity and specificity of 0.80 and 0.92, respectively, with a summary receiver operating characteristic (SROC) curve and an area under the curve (AUC) of 0.91. PCT in determining the need for surgery achieved a cutoff of 0.12 ng/mL (Youden index: 0.8), with sensitivity and specificity of 0.75 and 0.74 (AUC: 0.79). NLR showed a cutoff of 7.2 (Youden index: 0.68), yielding sensitivity and specificity of 0.74 and 0.83 (AUC: 0.84) in the diagnosis of bowel ischemia. D-dimer (cutoff: 1.72 mg/L, Youden index: 0.91) and lactate (cutoff: 2.98 mmol/L, Youden index: 0.8) exhibited sensitivities of 0.83 and 0.77, specificities of 0.70 and 0.79, and AUCs of 0.85 for both, in the diagnosis of bowel ischemia.CONCLUSIONNLR, CRP, PCT, D-dimer, and lactate may provide supplementary diagnostic value for bowel ischemia in patients with bowel obstruction. A PCT threshold > 0.12 ng/mL may assist in evaluating the need for surgery.","PeriodicalId":48867,"journal":{"name":"World Journal of Emergency Surgery","volume":"837 1","pages":"80"},"PeriodicalIF":8.0,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145338683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of artificial intelligence (AI) offers a promising approach for bridging this gap. We aimed to develop an AI-based model to predict mortality and prolonged ICU stay in postoperative critically ill patients, enhance prognostic accuracy, and address the shortcomings of current models. This retrospective study included data from 6,029 postoperative critically ill patients from two medical centers, including a wide range of clinical, surgical, and laboratory variables. Multiple machine-learning models, including extreme gradient boosting, light gradient boosting, category boosting, random forest, and multilayer perceptron, were employed. A soft-voting ensemble model was developed to aggregate the strengths of individual models. The models underwent external validation, and the SHapley Additive exPlanations (SHAP) method was utilized to assess the impact of various features on predictions. In internal validation, the ensemble model demonstrated superior performance with an area under the receiver operating characteristic curve (AUROC) of 0.8812 for mortality and 0.7944 for prolonged ICU stay. It achieved 0.9095 accuracy and an F1 score of 0.7014 for mortality predictions. For prolonged ICU stay, it attained an accuracy of 0.9368 and an F1 score of 0.5762. During external validation, the model maintained high performance, with an AUROC of 0.8330 for mortality and 0.7376 for prolonged ICU stay. It showed 0.9200 accuracy and an F1 score of 0.6768 for mortality and 0.9028 accuracy with an F1 score of 0.5689 for prolonged ICU stay. SHAP analysis confirmed that key predictors, including emergency surgery, serum osmolality, lactate levels, and diastolic blood pressure, remained significant. This study represents a significant advancement in the application of AI in critical care, especially for postoperative critically ill patients. The developed AI model outperformed existing models in predicting mortality and prolonged ICU stay, demonstrating notable accuracy and reliability. Its ability to identify critical, under-emphasized clinical factors could enhance decision-making in critical care settings. Although promising, further validation in diverse clinical settings is essential to confirm the model’s efficacy and broader applicability.","PeriodicalId":48867,"journal":{"name":"World Journal of Emergency Surgery","volume":"9 1","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145289192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional static IAP monitoring inadequately captures dynamic injury evolution. This study aimed to assess the impact of cumulative IAP exposure (CumIAP) and dynamic trajectories on the prognosis of SAP. This retrospective cohort study analyzed 1,008 ICU-admitted SAP patients from the Jiangxi cohort (2005–2023) and 83 from MIMIC-IV (2008–2019). CumIAP was quantified via time-weighted integration of serial IAP measurements. Multivariate Cox regression models and restricted cubic splines (RCS) were established to analyze the dose–response relationships between CumIAP and death, infectious pancreatic necrosis (IPN), and persistent multiple organ failure (PMOF). Mediation analysis evaluated CumIAP’s role in albumin (ALB)- and acute necrotic collection (ANC)-associated outcomes. Latent class growth mixture model (LCGMM) was employed to identify dynamic IAP trajectory subtypes, and the associations between each trajectory group and poor prognosis were analyzed. Over a median inpatient follow-up of 17 days in the Jiangxi cohort, 200 (19.8%) patients died in hospital, while 208 (20.6%) and 329 (32.6%) developed IPN and PMOF, respectively. Regression analysis revealed that for each standard deviation increase in CumIAP, the risks of in-hospital death and PMOF increased by 37% and 86%, respectively, and there was a U-shaped association with the risk of IPN (P for nonlinearity = 0.004). Mediation analysis showed that CumIAP mediated 24.26% and 33.76% of the associations between ALB, ANC, and the risk of in-hospital death, respectively. Three IAP trajectories were identified by LCGMM: the high-pressure rapid decline group (HRD-T1), the low-pressure gradual decline group (LGD-T2), and the low-pressure progressive increase group (LPI-T3). Among them, compared with HRD-T1 and LGD-T2, the subjects in the LPI-T3 group had a significantly increased risk of adverse clinical outcomes. This is the first study to revealed that CumIAP is linearly positively correlated with death and PMOF, while exhibits a U-shaped relationship with IPN. Notably, patients with low baseline IAP and a rising trajectory exhibited worse outcomes than those with high baseline IAP and a declining trend. This is the first study to introduce CumIAP as a quantitative metric to assess the early IAP burden and its prognostic significance in SAP, overcoming the limitations of static IAP monitoring. RCS and regression analyses revealed a positive linear association between CumIAP and in hospital mortality/PMOF, and a U-shaped relationship with IPN, suggesting the possible presence of a risk threshold.

Burn patients often experience androgen depletion, exacerbating these issues. Oxandrolone, a synthetic anabolic steroid, has shown promise in counteracting these metabolic disturbances. This updated meta-analysis evaluates the efficacy and safety of oxandrolone in burn patients, incorporating recent studies, pediatric populations, long-term outcomes, and combination therapies. This PRISMA 2020-compliant systematic review searched 9 databases (PubMed, Embase, Cochrane, WOS, WHO-ICTRP, CNKI, VIP, Wanfang, CBMdisc) for RCTs published between 2005 and 2025 using validated strategies combining controlled vocabulary (MeSH/Emtree) and free-text terms for burn/trauma AND androgen analogs (e.g., oxandrolone, nandrolone). Included trials compared androgen analogs vs. controls (placebo/standard care) in burn patients, reporting ≥ 1 predefined outcome: (1) Lean body mass (recovery phase, ≥ 14 days post-burn); (2) Mild side effects (hepatic dysfunction [ALT/AST ≥ 2 × ULN] or edema); (3) Infections; (4) Mortality; (5) Surgical procedures; (6) LOS/TBSA; (7) Absolute LOS. Dual-independent screening, data extraction, and risk-of-bias assessment (Cochrane RoB 2.0 per outcome) were performed. Random-effects meta-analyses generated standardized mean differences (SMD) for continuous outcomes and risk ratios (RR) for dichotomous outcomes with 95% CIs. Fourteen RCTs (2005–2025; n = 2822 patients: 1203 intervention vs. 1619 controls) demonstrated significant reductions in surgical procedures (SMD = − 1.25; 95% CI − 2.45 to − 0.04; p = 0.04; I2 = 97.2%) and length of stay normalized to TBSA (LOS/TBSA) (SMD = − 1.07; 95% CI − 2.43 to 0.29; p = 0.007; I2 = 98.1%), alongside enhanced anabolic recovery evidenced by increased weight gain (SMD = 0.58; 95% CI − 1.21 to 2.38; p < 0.001) and lean mass (SMD = 1.30; 95% CI − 0.47 to 3.24; p < 0.001; I2 ≥ 95.0%). However, no mortality benefit was observed (RR = 1.04; 95% CI 0.47–2.32; p = 0.913; I2 = 66.5%), with unchanged infection rates (RR = 0.83; 95% CI 0.67–1.02; p = 0.639) and no improvement in donor site healing (SMD = − 1.48; 95% CI − 2.18 to 0.77; p = 0.116). Safety analysis revealed a non-significant increase in treatment-related side effects (hepatic dysfunction/edema; RR = 1.82; 95% CI 0.52–6.42; p = 0.34), notably higher transaminase elevations in adults (19% vs. 5% placebo; p = 0.002). Oxandrolone demonstrates clinical utility in burn management by significantly reducing surgical burden (SMD = − 1.25; p = 0.04), shortening hospitalization (LOS/TBSA SMD = − 1.07; p = 0.007), and enhancing anabolic recovery (weight gain SMD = 0.58; lean mass SMD = 1.30; both p < 0.001).

In further analysis we assess the contribution of post-surgery patient characteristics. Data from 686 patients undergoing emergency abdominal surgery (50.4% female; mean age 66.6 (standard deviation (SD) 12.8) years; 50.1% with intestinal obstruction as indication for surgery), with QoL measurements were analysed. Shortly after surgery (mean days 7.59 (SD 7.48)), the mean EQ-5D-3L QoL utility score was 0.21 (SD 0.46), which improved among survivors to 0.74 (SD 0.31) in the medium- to long-term (i.e., three to eight months) following surgery. Patient’s sex and preoperative risk of mortality were key determinants of QoL shortly after surgery. In addition to time since surgery, patient’s sex, Charlson Comorbidity index, ASA physical status and indication for surgery were key pre-surgery predictors of QoL in the medium- to long-term post-surgery. From post-surgery characteristics, duration of hospital admission for index surgery and further days in hospital within 30 days prior to QoL measurement were key further determinants of QoL in the medium- to long-term.

While higher platelet-to-red blood cell (PLT/RBC) transfusion ratios may improve outcomes, the optimal ratio remains unclear. This study aimed to determine the threshold of PLT/RBC ratio and its impact on in-hospital mortality in trauma patients requiring massive transfusions. This retrospective, multicenter study used 2014–2018 National Trauma Database (NTDB) data. Adult patients admitted to Level I/II trauma centers with massive transfusions within 24 h of emergency department (ED) admission were included. Patients were divided into high-PLT group (PLT/RBC ratio > 0.7) and low-PLT group (ratio ≤ 0.7). Primary outcomes: 24-hour and 30-day mortality; secondary outcomes: transfusion-related adverse events. Among 9,330 patients (median age 37 (26–54) years; 78.9% male), 46.1% had a high PLT/RBC ratio. Restricted cubic spline analysis revealed a nonlinear relationship: mortality dropped significantly at > 0.7 and stabilized above 1.5. After inverse probability treatment weighting, the high-PLT group showed lower 24-hour mortality (OR, 0.45; 95% CI, 0.42–0.48) and 30-day mortality (OR, 0.66; 95% CI, 0.62–0.70). However, the high ratio group experienced higher rates of adverse events, including pulmonary embolism, acute kidney injury, and sepsis. Subgroup analyses confirmed consistent survival benefits despite increased adverse events. Sensitivity analysis further supported the robustness of these findings. In this multicenter study, a high PLT/RBC ratio (> 0.7) was associated with improved survival in trauma patients requiring massive transfusions, reducing 24-hour and 30-day mortality. However, it also increased the risk of adverse events, with a ceiling effect observed at ratios above 1.5.

Accurate intra-abdominal pressure (IAP) measurement is essential for effective diagnosis, prevention, and treatment. Previous studies indicate that accurate IAP measurement using traditional Foley catheters requires the bladder to be filled with a maximum of 25 mL of sterile saline solution after clamping the catheter, restricting the ability to monitor IAP continuously due to variations in the bladder fill volume. The TraumaGuard catheter enables continuous IAP measurement irrespective of bladder fill volume. The primary objective was the validation of the TraumaGuard catheter (Sentinel Medical Technologies, Jacksonville, Florida, USA), a new continuous bladder pressure monitoring device. ICU patients were studied across different body positions to assess measurement accuracy by comparing the correlation, bias, precision, and agreement between IAP readings obtained using the TraumaGuard catheter and the FoleyManometer measurement method (SecurMeter, Deltamed, Viadana, Italy), which serves as the gold standard. The secondary endpoint of this study was to investigate the impact of different body positions on IAP. Adult ICU patients (≥ 18 years) requiring bladder catheterisation were enrolled. IAP was measured using a TraumaGuard catheter (IAPTG) and FoleyManometer method (IAPFM) across multiple positions to have a broad range of IAP values and to study the impact of body position on IAP measurement. Pairwise analysis of IAPTG and IAPFM in the supine, reverse Trendelenburg (15°, 30°, and 45°), and head-of-bed (HOB) elevation positions (15°, 30°, and 45°) was performed using correlation, concordance, and Bland-Altman analyses. The error-grid analysis assessed the risk associated with inaccurate measurements at each body position. The robustness of the TraumaGuard catheter as a detection system for IAH detection system was evaluated by receiver operating characteristic (ROC) curve. The IAP variation as a function of body position was investigated and compared with the reviewed literature. Gender, age, body mass index (BMI), and sequential organ failure assessment (SOFA) score were also recorded for each participant. Twenty-five adult ICU patients with a mean age of 63.6 ± 11.6 years and BMI of 28.3 ± 3.7 kg/m2 were included. The mean IAP increased from 9.8 ± 1.7 mmHg in supine to 10.4 ± 1.5 mmHg in reverse Trendelenburg and 14.9 ± 1.6 mmHg in HOB elevation positions.
