Graves' orbitopathy development in thyroid cancer patients: a 16-year nationwide cohort study in South Korea.

Background/objectives: We aimed to investigate the prevalence, risk factors, and prognosis of Graves' orbitopathy (GO) in patients with thyroid cancer without a history of hyperthyroidism.

Subjects/methods: This retrospective cohort study analysed a sample from the Korean National Health Insurance Service database, which included 1,137,861 subjects from 2002 through 2019. Patients diagnosed with thyroid cancer, without a history of hyperthyroidism, were identified according to the Korean Standard Classification of Disease codes.

Sex-specific risk factors associated with graves' orbitopathy in Korean patients with newly diagnosed graves' disease.

Objective: To assess sex-specific risk factors for Graves' orbitopathy (GO) in newly diagnosed Graves' disease (GD) patients.

Methods: A retrospective cohort study was conducted using the National Health Insurance Service's sample database, which consisted of 1,137,861 subjects from 2002 to 2019. The international classification of disease-10 codes was used to identify those who developed GD (E05) and GO (H062).

Effect of stent graft fixation types on pararenal aortic diameter and renal function after endovascular aortic repair.

Background: This study aims to identify pararenal aortic diameter changes following endovascular aortic repair and to investigate the effects of suprarenal fixation on renal function.

Methods: Between May 2006 and January 2019, a total of 168 patients (135 males, 33 females; mean age: 75.2±8.

Changes in Clinical Features and Demographics in Donors After Brain Death Over the Past 20 Years: A Single-Center Experience in the Republic of Korea.

Objectives: We investigated clinical characteristics and demographics of brain death in patients from a single center in Korea to identify possible changes in organ procurement by comparing early and late periods.

Materials And Methods: Potential donors diagnosed as brain dead and who had provided organ donation consent from May 2000 to May 2020 were considered. Donors were divided into 2 categories: early period (2000-2010) and late period (2011-2020).

Laparoscopic internal fixation is a viable alternative option for continuous ambulatory peritoneal dialysis catheter insertion.

Purpose: One of the major drawbacks of peritoneal dialysis (PD) is catheter migration and dysfunction. Preventing catheter migration is one of the main concerns. We compared laparoscopic internal fixation method with open surgical method for catheter migration rates.

View image generation in perspective and orthographic projection geometry based on integral imaging.

A novel technique generating arbitrary view images in perspective and orthographic geometry based on integral imaging is proposed. After capturing three-dimensional object using a lens array, disparity estimation is performed for the pixels at the selected position of each elemental image. According to the estimated disparity, appropriate parts of elemental images are mapped to synthesize new view images in perspective or orthographic geometry.

Point light source integral imaging with improved resolution and viewing angle by the use of electrically movable pinhole array.

A resolution and viewing-angle enhanced integral imaging system using electrically movable pinhole array is proposed. A pinhole array on liquid crystal is adopted as dynamic pinhole array in integral imaging. The location of the pinhole array is controlled electrically.

Cystamine prevents ischemia-reperfusion injury by inhibiting polyamination of RhoA.

Transglutaminase2 (TGase2) activates Rho-associated kinase (ROCK), an important mediator of ischemia-reperfusion (IR) injury, through polyamination of RhoA. Cystamine, an oxidized dimer of cysteamine inhibits the transamidation activity of TGase2. We examined whether addition of cystamine to an organ preservation solution protects rat cardiomyocyte cells (H9C2) from cell death in IR injury.
