Background: Cardiac auscultory skills are declining. Hand-carried ultrasound (HCU) has been proposed as a method to enhance diagnostic accuracy of the physical examination (PE). However, features of HCU devices are varied.
Objective: The aim of this study was to compare the diagnostic accuracies of an experienced pediatric cardiac PE alone vs. the PE combined with the assistance of an HCU device when using 2 HCU devices with different capabilities. The results were compared with conventional echo as the reference standard.
Methods: All outpatients seen by a single pediatric cardiologist underwent physical examination and HCU. Two HCU devices were compared. The first HCU device (HCU-1) had limited options with only 2-dimensional echo, limited Doppler, and a single transducer frequency (2.5 MHz). The second HCU device (HCU-2) was a unit with greater transducer choices and a wider variety of applications. A single echocardiologist performed the PEs & HCUs. Conventional echoes were performed by a pediatric sonographer and interpreted by a second pediatric echocardiologist. Examination accuracies centered on 3 broad areas including: cardiac shunts, valvular insufficiency, and valvular anatomy. The accuracy of the PE alone was compared with the accuracy of the combined PE & HCU-1 vs. PE & HCU-2.
Results: Thirty patients total (3 months-19 years, 4-82 kg) were evaluated. Eighteen were examined with HCU-1 and 12 were examined with HCU-2. The accuracy of the combined PE & HCU-1 did not improve accuracy over the PE alone. However, the accuracy of the combined PE & HCU-2 was greater than the PE alone.
Conclusions: Use of a limited HCU device does not improve diagnostic accuracy over an experienced PE alone and may actually worsen diagnostic accuracy in some cases. However, the improvements in newer HCU devices may enhance diagnostic accuracy over the PE alone, even for experienced physicians.

Rationale And Objectives: Extrathyroidal extension (ETE) and BRAF mutation in papillary thyroid cancer (PTC) increase mortality and recurrence risk. Preoperative identification presents considerable challenges. Although radiomics has emerged as a potential tool for identifying ETE and BRAF mutation, systematic evidence supporting its effectiveness remains insufficient.

Rationale And Objectives: Training Convolutional Neural Networks (CNN) requires large datasets with labeled data, which can be very labor-intensive to prepare. Radiology reports contain a lot of potentially useful information for such tasks. However, they are often unstructured and cannot be directly used for training.

Purpose: To compare voiding parameters in women with and without increased postvoid residual (PVR) volume, to correlate these parameters with PVR volume and PVR percentage, and to describe their ability to predict an increased PVR volume.
Methods: Retrospective cross-sectional study of urodynamics data prospectively acquired from consecutive symptomatic women over a 5-year period. Patients with spinal cord disorders and with abdominal straining during voiding (abdominal pressure ≥10 cm H2O over baseline at maximum flow rate [Qmax]) were excluded.

Objective: This study aimed to develop a predictive model using a random forest algorithm to determine the likelihood of postoperative adhesive small bowel obstruction (ASBO) in infants under 3 months with intestinal malrotation.
Methods: A machine learning model was used to predict postoperative adhesive small bowel obstruction using comprehensive clinical data extracted from 107 patients with a follow-up of at least 24 months. The Boruta algorithm was used for selecting clinical features, and nested cross-validation tuned and selected hyper-parameters for the random forest model.
