Objective: To investigate baseline and change of pulmonary damage biomarkers (serum Krebs von den Lungen 6 [KL-6], human surfactant protein D [hSP-D], and matrix metalloproteinase 7 [MMP-7]) with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) progression.

Methods: In the Korean Rheumatoid Arthritis Interstitial Lung Disease (KORAIL) cohort, a prospective cohort, we enrolled patients with RA and ILD confirmed by chest computed tomography imaging and followed annually. ILD progression was defined as worsening in physiological and radiological domains of the 2022 American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society guideline for progressive pulmonary fibrosis (PPF).

Objectives: We investigated the prevalence of anti-thyroid autoantibodies and thyroid dysfunction, and their association with clinical and laboratory features in Korean patients with primary Sjögren's syndrome (pSS) without overt thyroid illnesses.

Methods: We consequently included 196 pSS patients (190 women) and cross-sectionally collected clinical and laboratory data including the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) and Patient Reported Index (ESSPRI). The fatigue-dominant group was defined as those in the highest quartile of the fraction of fatigue, calculated as the ESSPRI fatigue score divided by the total ESSPRI score.

Purpose: Peripheral nerve injuries can lead to lasting functional impairments, impacting movement and quality of life. FK-506, a widely used immunosuppressant, has demonstrated potential in promoting nerve regeneration in addition to its immunosuppressive effects. This study investigates the use of a local reservoir flap to deliver FK-506 directly to the nerve injury site, aiming to enhance nerve regeneration while minimizing systemic immunosuppression.

Nano-transfer printing (nTP) has emerged as an effective method for fabricating three-dimensional (3D) nanopatterns on both flat and non-planar substrates. However, most transfer-printed 3D patterns tend to exhibit non-discrete and/or non-porous structures, limiting their application in high-precision nanofabrication. In this study, we introduce a simple and versatile approach to produce highly ordered, porous 3D cross-bar arrays through precise control of the nTP process parameters.

The carbon dioxide removal (CDR) capacity of macroalgae, a crucial component in climate regulation, has gained increasing attention. However, accurately estimating the CDR potential of macroalgae in natural conditions remains challenging, necessitating the use of multiple independent methods to reduce the uncertainties in these estimates. In this study, we compared two methods for estimating net ecosystem production (NEP), a key parameter in determining CDR potential: 1) NEP, derived from seawater carbonate chemistry and 2) NEP, based on photorespiratory measurements using benthic tent incubation.

Article Synopsis
  • - The study analyzed how poor prognostic factors (PPFs), such as functional limitations and bone erosions, impact remission rates and the need for advanced therapies (b/tsDMARDs) in a large group of Korean patients with rheumatoid arthritis (RA).
  • - Patients were divided into three groups based on the number of PPFs they had, with Group H (≥3 PPFs) showing more severe disease and poorer health outcomes compared to Groups L (0-1 PPFs) and M (2 PPFs).
  • - The findings indicate that patients in Group H found it much harder to achieve remission over five years and were more likely to require b/tsDMARD treatment, suggesting that higher P

  • In-depth investigation into medical costs before and after biopsies for kidney diseases in South Korea is essential for understanding risks and outcomes.
  • The study analyzed data from 1,390 patients diagnosed with glomerulonephritis (GN), tubulointerstitial nephritis (TIN), and acute tubular necrosis (ATN) between 2012 and 2018, linking clinical data to national medical claims.
  • Findings indicate that medical costs usually rise post-biopsy for most kidney diseases, with increased rates of serious health events noted in certain disease categories, highlighting critical epidemiological insights.

Background: Low muscle mass is associated with high insulin resistance and an increased risk of cardiovascular disease. This study aims to determine whether low muscle mass affects the alterations in myocardial substrate metabolism that are associated with the development of cardiovascular disease.

Method: The study included 299 individuals (182 men and 117 women) who underwent examination at the Severance Health Check-up Center between January 2018 and February 2019.

  • Akkermansia muciniphila (A. muciniphila) is a next-generation probiotic that plays a crucial role in regulating the gut-liver-brain axis, especially during liver injury, although its mechanisms are not fully understood.
  • Research involving cohorts of liver cirrhosis patients and animal models revealed that cognitive impairment is linked to reduced levels of A. muciniphila, along with changes in brain-derived neurotrophic factor (BDNF) and serotonin levels.
  • Administering A. muciniphila showed promise in improving cognitive dysfunction and reducing tissue damage associated with liver injury, suggesting it could be a potential therapy for liver fibrosis and related cognitive issues.

  • Mesonephric-type adenocarcinomas (MAs) are rare but aggressive ovarian tumors that can be difficult to diagnose due to their origin from Müllerian lesions.
  • A study was conducted involving a four-marker immunohistochemical (IHC) panel to distinguish MAs from similar tumors like endometrioid carcinoma, significantly improving diagnostic accuracy among pathologists.
  • The findings showed that MAs are linked to a higher risk of early death compared to endometrioid carcinoma, indicating that careful testing and diagnosis are crucial, especially in early-stage disease.
