Leveraging machine learning for preoperative prediction of supramaximal ablation in laser interstitial thermal therapy for brain tumors.

Objective: Maximizing safe resection in neuro-oncology has become paramount to improving patient survival and outcomes. Laser interstitial thermal therapy (LITT) offers similar survival benefits to traditional resection, alongside shorter hospital stays and faster recovery times. The extent of ablation (EOA) achieved using LITT is linked to patient outcomes, with greater EOA correlating with improved outcomes.

[Extended length of stay following robot-assisted minimally invasive pulmonary lobectomy: Is incomplete ERAS protocol to blame?].

Enhanced Recovery After Surgery (ERAS) is a series of measures designed to promote early recovery after surgery. Application of this approach has led to significantly decreased morbi-mortality and reduced length of hospital stay. The aim of our study was to determine whether non-completion of the ERAS protocol following robotic-assisted mini-invasive lobectomy could be the cause of prolonged hospital stay (exceeding 6 days).

APOE 𝜀4-related blood-brain barrier breakdown is associated with microstructural abnormalities.

Introduction: Blood-brain barrier (BBB) dysfunction occurs in Alzheimer's disease (AD). Yet, the stage at which it appears along the AD time course and whether it contributes to neurodegeneration remain unclear.

Methods: Older adults (61 to 90 years) from cognitively normal (CN) to mildly cognitively impaired (CI), enriched for APOE 𝜀4 and amyloid positivity, underwent dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) and diffusion MRI to measure BBB permeability and brain microstructure.

Machine learning for adverse event prediction in outpatient parenteral antimicrobial therapy: a scoping review.

Objective: This study aimed to conduct a scoping review of machine learning (ML) techniques in outpatient parenteral antimicrobial therapy (OPAT) for predicting adverse outcomes and to evaluate their validation, implementation and potential barriers to adoption.

Materials And Methods: This scoping review included studies applying ML algorithms to adult OPAT patients, covering techniques from logistic regression to neural networks. Outcomes considered were medication intolerance, toxicity, catheter complications, hospital readmission and patient deterioration.

Forensic International Dental Database (FIDBv2) for adult age-at-death estimation in multiple forensic contexts: Strengthening the operationalization of the Lamendin criteria in a global scope model.

The aim of this study is to validate the FIDBv2 online procedure for adult age-at-death estimation using root dentine translucency (RDT) and periodontal retraction (PR) of single-rooted teeth in a worldwide sample. The sample includes 4810 teeth of 2559 individuals from 16 countries of America, Europe and Asia. Bias and inaccuracy between documented (DA) and estimated ages (EA) were calculated.

Tranexamic Acid Is Not Associated With a Change in Infection Risk in Trauma Patients.

Introduction: Tranexamic acid (TXA) has been used as an adjunct in traumatic hemorrhage management. Outside of trauma, TXA has been used to limit blood loss across multiple surgical fields. TXA has also been found to have an immune-modulating effect, reducing postoperative infection rates.

Diagnostic Accuracy of a Custom Large Language Model on Rare Pediatric Disease Case Reports.

Accurately diagnosing rare pediatric diseases frequently represent a clinical challenge due to their complex and unusual clinical presentations. Here, we explore the capabilities of three large language models (LLMs), GPT-4, Gemini Pro, and a custom-built LLM (GPT-4 integrated with the Human Phenotype Ontology [GPT-4 HPO]), by evaluating their diagnostic performance on 61 rare pediatric disease case reports. The performance of the LLMs were assessed for accuracy in identifying specific diagnoses, listing the correct diagnosis among a differential list, and broad disease categories.
