Although esophageal cancer survivors experience lower health-related quality of life (HRQoL), it is hard to provide proper supportive care due to difficulties to find potential target population. This study aims to develop a trial-ready cohort (TRC) to assess the unmet needs and HRQoL of survivors of esophageal cancer. This prospective, multicenter TRC study will include 600 patients diagnosed with primary esophageal cancer who have undergone curative treatment.

Objective: Although breast magnetic resonance imaging (MRI) is a valuable screening tool, breast MRI testing burden was associated with cancer worry and quality of life. We aimed to develop and validate the MRI-related distress scale (MRI-DS) to assess comprehensive distress specifically related to breast MRI.

Methods: We enrolled women aged above 18 years, diagnosed breast cancer, had MRI examination at least one time, and who could speak and read Korean in phase I and enrolled women aged above 18 years, visited outpatient clinic of breast general surgery, had undergone MRI examination at least once, and could speak and read Korean in phase II.

Background: In recognition of the distinct clinical challenges and research gaps in young breast cancer (YBC) patients, we established the Comprehensive Young Age Breast Cancer (CHARM) registry to collect prospective data.

Methods: This prospective cohort included patients who were newly diagnosed with histologically confirmed breast cancer without prior treatment at the Samsung Medical Center (SMC) in April 2013. We included patients who were either 40 years old or younger at the time of diagnosis, pregnant at breast cancer diagnosis or diagnosed with breast cancer within 1 year of delivery.

This study examined how perceived threat moderates the effects of message type (humor vs. non-humor) on attitude and behavior intentions toward a mental health public service announcement (PSA) on a college campus. To investigate the relationships, a between-subject experimental survey was employed for 209 undergraduate students.

The mammalian intestinal tract contains trillions of bacteria. However, the genetic factors that allow gut symbiotic bacteria to occupy intestinal niches remain poorly understood. Here, we identified genetic determinants required for Bacteroides thetaiotaomicron colonization in the gut using transposon sequencing analysis.

Nonmedical use of prescription stimulants (NMUPS) among college students continues to rise. While some anti-NMUPS campaigns are available, little is known about the campaign development process and how well college students evaluate these messages. To bridge this gap, we developed theory-guided anti-NMUPS campaign interventions that are tailored to college students' characteristics and evaluated students' response towards them.

The defect evolution in graphene produced by ion beam bombardment is investigated by changing the ion species, irradiation energy and dose. Raman spectroscopy is performed to examine the defect yield produced under various ion beam bombardment conditions. The defect yields of the vacancy-type defect are well described by the linear energy transfer (L) and dose (d).

Large-scale 2D single-crystalline copper nanoplates (Cu NPLs) are synthesized by a simple hydrothermal method. The combination of a mild reductant, stabilizer, and shape modifier allows the dimensional control of the Cu nanocrystals from 1D nanowires (NWs) to 2D nanoplates. High-resolution transmission electron microscopy (HR-TEM) reveals that the prepared Cu NPLs have a single-crystalline structure.

Purpose: To investigate the effect of watching 3-dimensional (3D) television (TV) on refractive error in children.

Methods: Sixty healthy volunteers, aged 6 to 12 years, without any ocular abnormalities other than refractive error were recruited for this study. They watched 3D TV for 50 minutes at a viewing distance of 2.
