This study harnessed machine learning to forecast postoperative mortality (POM) and pneumonia (PPN) among surgical traumatic brain injury (TBI) patients. Our analysis centered on the following key variables: Glasgow Coma Scale (GCS), midline shift (MSB), time from emergency room arrival (TIE). Additionally, we introduced innovative clustered variables enhance predictive accuracy risk assessment. Exploring data 617 patients spanning 2012 2022, observed that 22.9% encountered mortality, while 30.0% faced (PPN). Sensitivity for POM PPN prediction, before incorporating clustering, was in ranges of 0.43-0.82 0.54-0.76 Following sensitivity values were 0.47-0.76 0.61-0.77 Accuracy 0.67-0.76 0.70-0.81 prior clustering 0.42-0.73 0.55-0.73 after clustering.

Abstract Background Postoperative pulmonary complications (PPCs) remain a prevalent concern among elderly surgical patients, with notably higher incidence observed in the undergoing thoracic surgery. This study aimed to construct nomogram predict risk of PPCs this population. Methods A total 2963 patients who underwent surgery were randomly enrolled and divided into training cohort (80%, n = 2369) validation (20%, 593). Univariate multivariate logistic regression analyses conducted identify factors for PPCs, was developed based on findings from cohort. The used validate model. predictive accuracy model evaluated by receiver operating characteristic curve (ROC), area under ROC (AUC), calibration decision analysis (DCA). Results 918 (31.0%) reported PPCs. Nine independent identified: preoperative presence chronic obstructive disease (COPD), elevated leukocyte count, partial pressure arterial carbon dioxide (PaCO2) levels, location surgery, thoracotomy, intraoperative hypotension, blood loss > 100 mL, duration 180 min malignant tumor. AUC value 0.739 (95% CI: 0.719–0.762), that 0.703 0.657–0.749). P values Hosmer-Lemeshow test 0.633 0.144 cohorts, respectively, indicating good fit. DCA showed could be applied clinically if threshold between 12% 84%, which found 8% 82% Conclusions underscores pressing need early detection exhibited promising efficacy individuals enabling identification high-risk consequently aiding implementation preventive interventions.

Abstract Background Respiratory complications after thoracic surgery are common and can lead to increased perioperative morbidity mortality. Although several clinical risk scores for the prediction of respiratory have been proposed, these not specific surgery. In addition, few adopted in practice due lack external validation. Our thoracic-specific score, CARDOT showed good predictive performance postoperative during score development. This study aimed validate an dataset determine including neutrophil-lymphocyte ratio (NLR) as additive predictor. Methods A retrospective cohort consecutive surgical patients at a single tertiary hospital northern Thailand was conducted. The development validation datasets were collected between 2006 2012 from 2015 2021, respectively. Six prespecified factors identified, formed (chronic obstructive pulmonary disease, American Society Anesthesiologists physical status, right-sided operation, duration surgery, oxygen saturation, thoracotomy), calculated. evaluated terms discrimination by using area under receiver operating characteristic (AuROC) curve calibration. Results incidence 15.7% (171 1088) 24.6% (370 1642), dataset. had discriminative ability both (AuROC 0.789 (95% CI 0.753–0.827) 0.758 0.730–0.787), respectively). calibration datasets. high NLR (≥ 4.5) significantly (P < 0.001). AuROC with greater power than that alone = 0.008). Conclusions consistent tool may be beneficial settings where preoperative function tests routinely performed.

Background: Sleeve lobectomy is a challenging procedure with high risk of postoperative complications. To facilitate surgical decision-making and optimize perioperative treatment, we developed stratification models to quantify the probability complications after sleeve lobectomy. Methods: We retrospectively analyzed clinical features 691 non-small cell lung cancer (NSCLC) patients who underwent between July 2016 December 2019. Logistic regression were trained validated in cohort predict overall complications, major specific minor The impact prognostic was explored via Kaplan-Meier method. Results: Of included patients, 232 (33.5%) including 35 (5.1%) 197 (28.5%) respectively. showed robust discrimination, yielding an area under receiver operating characteristic (ROC) curve (AUC) 0.853 [95% confidence interval (CI): 0.705–0.885] for predicting complication 0.751 (95% CI: 0.727–0.762) specifically risks. Models also achieved good performance, AUCs ranging from 0.78 0.89. Survival analyses revealed significant association poor prognosis. Conclusions: Risk could accurately severity NSCLC following lobectomy, which may inform future patients.
