Risk Factors for Gastrointestinal Bleeding in Patients With Acute Myocardial Infarction: Multicenter Retrospective Cohort Study.

Background: Gastrointestinal bleeding (GIB) is a severe and potentially life-threatening complication in patients with acute myocardial infarction (AMI), significantly affecting prognosis during hospitalization. Early identification of high-risk patients is essential to reduce complications, improve outcomes, and guide clinical decision-making.

Objective: This study aimed to develop and validate a machine learning (ML)-based model for predicting in-hospital GIB in patients with AMI, identify key risk factors, and evaluate the clinical applicability of the model for risk stratification and decision support.

Surrogate End Points for Overall Survival in Neoadjuvant Randomized Clinical Trials for Early Breast Cancer.

Purpose: To assess trial-level surrogacy value for overall survival (OS) of the pathologic complete response (pCR) and invasive disease-free survival (iDFS) in randomized clinical trials (RCTs) for early breast cancer (BC).

Methods: Individual patient data of neoadjuvant RCTs with available data on pCR, iDFS, and OS were included in the analysis. We used the coefficient of determination from weighted linear regression models to quantify the association between treatment effects on OS and on the surrogate end points.

Intraprocedural Three-Dimensional Imaging Registration Optimizes Magnetic Resonance Imaging-Guided Focused Ultrasound and Facilitates Novel Applications.

Background And Objective: Transcranial magnetic resonance-guided focused ultrasound (MRgFUS) has revolutionized ablative treatment of essential tremor in recent years. However, limitations in precision targeting may account for suboptimal efficacy and significant side effects. We describe a simple intraprocedural three-dimensional image-guided lesion shaping technique that can improve overall outcomes of MRgFUS for essential tremor and facilitate expansion to novel indications.

Clinical Evaluation of the NaviNetics Stereotactic System Using Intraoperative Portable Surgical Imaging System in DBS Surgery.

Background And Objectives: A typical workflow for deep brain stimulation (DBS) surgery consists of head frame placement, followed by stereotactic computed tomography (CT) or MRI before surgical implantation of the hardware. At some institutions, this workflow is prolonged when the imaging scanner is located far away from the operating room, thereby increasing workflow times by the addition of transport times. Recently, the intraoperative O-arm has been shown to provide accurate image fusion with preoperative CT or MR imaging, suggesting the possibility of obtaining an intraoperative localization scan and postoperative confirmation.

Supratotal Resection Versus Gross Total Resection for Isocitrate Dehydrogenase-Wildtype Glioblastoma and Grade 4 Isocitrate Dehydrogenase-Mutant Astrocytoma: Meta-Analysis of Individual Patient Data.

Background And Objectives: IDH-wildtype glioblastoma multiforme (GBM) and grade 4 IDH-mutant astrocytoma are challenging to manage in oncology. This study explores the contrast between gross total resection (GTR) and supratotal resection (SupTR) for IDH-wildtype GBM and grade 4 IDH-mutant astrocytoma, aiming to summarize their influence on crucial clinical outcomes.

Methods: This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

T-Bar Angular Offset: A Novel Angle for Predicting Postoperative Coronal Balance Using Intraoperative Stitched Radiographs.

Background And Objectives: Accurate intraoperative assessment of coronal alignment is critical to achieving favorable clinical outcomes in adult spinal deformity surgery. However, surgical positioning creates challenges in predicting standing coronal alignment. Gravity-based plumblines require an upright posture and are not possible intraoperatively.

Ultra-Low-Field Portable Brain Magnetic Resonance Imaging in Patients With Cardiac Devices: Current Evidence and Future Directions.

The use of cardiac devices, including mechanical circulatory support (MCS), cardiac implantable electronic devices (CIEDs), and pacing wires, has increased and significantly improved survival in patients with severe cardiac failure. However, these devices are frequently associated with acute brain injuries (ABIs) including ischemic strokes, intracranial hemorrhages, seizures, and hypoxic-ischemic brain injury which contribute substantially to morbidity and mortality. Computed tomography (CT) and magnetic resonance imaging (MRI), the standard imaging modalities for ABI diagnosis, can pose significant challenges in this patient population due to the risks associated with patient transportation and the incompatibility of ferromagnetic components of certain cardiac devices with high magnetic field of the MRI.

Review of Endosaccular Flow Disrupters for Wide-Neck Aneurysm Treatment.

Endosaccular flow disruption has emerged as a transformative approach for treating wide-neck intracranial aneurysms, which are characterized by neck diameters exceeding 4 millimeters or dome-to-neck ratios below 2. This review examines the technical specifications and clinical outcomes of major endosaccular devices, including the Woven EndoBridge (WEB) device, the Artisse embolization device, the Medina embolization device, the neck bridging device for bifurcation aneurysms, the polycarbonate urethane membrane-assisted device, the Galaxy saccular endovascular aneurysm lattice, and the Contour Neurovascular System. Analysis of pivotal trials reveals varying degrees of efficacy and safety across platforms.
