Scientists at Khon Kaen University’s Cholangiocarcinoma Research Institute apply MALDI-TOF MS to profile serum peptides and build SVM and Random Forest models. Their approach, based on 71 selected peptide mass fingerprints, distinguishes hepato-pancreato-biliary cancers from healthy controls with over 98% accuracy, demonstrating strong multiclass discrimination.

Key points

• MALDI-TOF MS detects 1,100 serum peptide features; feature selection via PLS-DA VIP ≥1 and ANOVA (p<0.05) yields 71 informative peptides.
• SVM and RF models trained on 71 PMFs achieve >98% accuracy, AUROC ~0.999, and MCC >0.95 in binary healthy vs. HPB cancer classification.
• RF multiclass classification yields out-of-bag error rates of 2.2% (training) and 3.5% (testing), demonstrating robust HPB cancer subtype discrimination.

Why it matters: This minimally invasive peptide-based platform could transform early detection and clinical management of aggressive HPB cancers.

A team at Montefiore Medical Center and Albert Einstein College of Medicine develops a multimodal XGBoost model integrating structured EMR variables and NLP of surgeon notes to identify outlier total and variable costs in spinal surgery, enabling risk-adjusted bundled payments.

Key points

• Multimodal XGBoost model integrates structured EMR data and NLP-processed surgeon notes to predict spinal surgery cost outliers with ROC-AUCs of 0.845 and 0.883.
• The study identifies 11% of patients as cost outliers, linking higher ICU admissions and reoperations to $12.8M in losses versus $1.8M profit for non-outliers.
• A four-tier Patient-Specific Payment Model uses power-transformed predicted probabilities to adjust bundled payment weights, ensuring equitable risk-based reimbursements.

Why it matters: This AI-driven risk stratification introduces equitable, patient-specific payment adjustments, enhancing value-based care models and reducing financial penalties for high-risk spinal surgery cases.

A research team at Debre Markos University and University of Gondar employ a causal forest double machine learning framework to estimate the effect of tuberculosis preventive therapy on antiretroviral adherence in a large Ethiopian cohort. Leveraging orthogonalized random forests, they quantify a modest average adherence reduction and reveal clinical subgroups that experience differential treatment responses.

Key points

• Applied causal forest DML using random forest propensity and outcome models with orthogonalization to estimate TPT effect on ART adherence.
• Found a 3.14 percentage point decrease in adherence (ATE=−0.0314; 95% CI [−0.0373, −0.0254]; p<0.001) in a cohort of 4,152 Ethiopian HIV patients.
• Identified treatment effect heterogeneity: improved adherence in patients with advanced WHO stage, longer ART duration, higher BMI, older age; reduced adherence in those with higher CD4, functional impairment, CPT use.

Why it matters: Causal machine learning reveals treatment effect heterogeneity in TPT’s impact on ART adherence, enabling personalized TB prevention strategies in HIV care.
