Background: Idiopathic normal pressure hydrocephalus (iNPH) predominantly manifests with gait disturbances, yet clinical assessments are vulnerable to confirmation bias, particularly post-shunt surgery. Blinded video evaluations are a method to enhance objectivity in gait assessment, but their reliability has never been systematically investigated. The aim was to evaluate the inter-rater reliability of blinded gait assessments in iNPH patients and to investigate how these assessments correlate with the Hellström iNPH scale and patient-reported health status following shunt surgery.

Aim: The purpose of this study was to assess the accuracy of a customized deep learning model based on CNN and U-Net for detecting and segmenting the second mesiobuccal canal (MB2) of maxillary first molar teeth on cone beam computed tomography (CBCT) scans.
Methodology: CBCT scans of 37 patients were imported into 3D slicer software to crop and segment the canals of the mesiobuccal (MB) root of the maxillary first molar. The annotated data were divided into two groups: 80% for training and validation and 20% for testing.

Background: Patent foramen ovale (PFO) has been identified as a potential risk factor for cryptogenic stroke (CS). Although transesophageal echocardiography (TEE) is considered the gold standard for PFO detection, false-negative results remain a clinical concern, particularly in CS patients with high suspicion of PFO-related etiology.
Aims: To evaluate the clinical utility of transcatheter PFO exploration (TPFOE) in CS patients with negative TEE findings but high suspicion of PFO-related etiology.

Background: This study evaluates the accuracy of an Artificial Intelligence (AI) system, specifically a convolutional neural network (CNN), in classifying elbow fractures using the detailed 2018 AO/OTA fracture classification system.
Methods: A retrospective analysis of 5,367 radiograph exams visualizing the elbow from adult patients (2002-2016) was conducted using a deep neural network. Radiographs were manually categorized according to the 2018 AO/OTA system by orthopedic surgeons.

Background: The cluster of differentiation 47 (CD47)-signal regulatory protein alpha (SIRPα) axis is a key regulator of innate immune surveillance, facilitating the neoplastic evasion of macrophage-mediated phagocytosis. Although this pathway has been implicated in tumor immune escape in multiple malignancies, its clinical and prognostic significance in esophageal squamous cell carcinoma (ESCC) remain to be fully elucidated.
Methods: We retrospectively analyzed 100 patients who underwent esophagectomy for resectable ESCC.
