Nutritional Intensive Support in a Pediatric Patient With Severe Traumatic Brain Injury: A Case Report.

Estimating the nutritional requirements for pediatric patients requires a comprehensive approach with various factors including age, gender, body mass index, and physical activity level, due to the significant growth and developmental changes observed in this population. This complexity renders the use of a simplistic generalization or a standard formula impractical. A number of methodologies have been established to calculate nutritional needs for the pediatric population.

Nationwide monitoring of legacy and emerging persistent organic pollutants and polycyclic aromatic hydrocarbons along the Korean coast.

Comprehensive studies simultaneously investigating the occurrence of chemicals of concern are limited. In this study, sediments and bivalves were collected from 24 locations along the Korean coast to evaluate the relative distribution, contamination characteristics, and ecological risks of legacy/emerging persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs). Our findings reveal that the concentrations of these contaminants were comparable to or lower than historical levels in the same Korean coast and other Asian countries.

The total concentrations in the seawater samples were 4.73-8.

Gallbladder Polyp Classification in Ultrasound Images Using an Ensemble Convolutional Neural Network Model.

Differential diagnosis of true gallbladder polyps remains a challenging task. This study aimed to differentiate true polyps in ultrasound images using deep learning, especially gallbladder polyps less than 20 mm in size, where clinical distinction is necessary. A total of 501 patients with gallbladder polyp pathology confirmed through cholecystectomy were enrolled from two tertiary hospitals.

Clinical Practice Guidelines for the Endoscopic Management of Peripancreatic Fluid Collections.

Endoscopic ultrasonography-guided intervention has gradually become a standard treatment for peripancreatic fluid collections (PFCs). However, it is difficult to popularize the procedure in Korea because of restrictions on insurance claims regarding the use of endoscopic accessories, as well as the lack of standardized Korean clinical practice guidelines. The Korean Society of Gastrointestinal Endoscopy (KSGE) appointed a Task Force to develope medical guidelines by referring to the manual for clinical practice guidelines development prepared by the National Evidence-Based Healthcare Collaborating Agency.
