Electronic address:

Article Synopsis
  • - This study investigates how colorectal cancer progresses, particularly the shift towards more aggressive, metastatic behavior as tumors invade surrounding tissues.
  • - It defines "evolution" as the transition from structured tumor formations to invasive cancer cell growth, focusing on cancer cell buddings at the invasive front.
  • - The research identifies two types of senescent tumor cells (Type I and Type II) that contribute differently to cancer progression, with Type II being significant for local invasion and lymph node metastasis, which may influence patient outcomes.

Keratinocyte-derived circulating microRNAs in extracellular vesicles: a novel biomarker of psoriasis severity and potential therapeutic target.

J Transl Med

March 2024

Department of Dermatology, Ajou University School of Medicine, Ajou University Hospital, 164, World Cup-Ro, Yeongtong-Gu, Suwon-Si, Gyeonggi-Do, 16499, South Korea.

Background: Psoriasis is a chronic inflammatory disorder characterized by pathogenic hyperproliferation of keratinocytes and immune dysregulation. Currently, objective evaluation tools reflecting the severity of psoriasis are insufficient. MicroRNAs in extracellular vesicles (EV miRNAs) have been shown to be potential biomarkers for various inflammatory diseases.

Article Synopsis
  • The study investigates the necessity of sentinel lymph node biopsy (SLNB) in patients with ductal carcinoma in situ (DCIS) who underwent either total mastectomy (TM) or breast-conserving surgery (BCS), highlighting concerns about complications and quality of life.
  • Researchers analyzed data from over 18,000 patients diagnosed with pure DCIS to compare outcomes and clinicopathological factors based on whether they had axillary surgery.
  • The findings indicate that axillary surgery does not impact survival rates in DCIS patients, suggesting that it may be more relevant for high-risk individuals, particularly those with larger tumors.

Although 20 % of patients with depression receiving treatment do not achieve remission, predicting treatment-resistant depression (TRD) remains challenging. In this study, we aimed to develop an explainable multimodal prediction model for TRD using structured electronic medical record data, brain morphometry, and natural language processing. In total, 247 patients with a new depressive episode were included.

Department of Radiology and Research Institute of Radiological Science and Center for Clinical Imaging Data Science, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, 03722, Seoul, Korea.

Article Synopsis
  • A study was done to see if a deep learning system could help doctors find brain metastasis (cancer spread) better when using special black-blood imaging techniques.
  • The system was tested on 365 patients, comparing how well four doctors could count and detect the brain tumors with and without the help of the deep learning tool.
  • Results showed that the deep learning system made diagnosing brain metastasis more accurate and quicker, cutting the average reading time from about 67 seconds to 57 seconds.

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) encompasses a broad and continuous spectrum of liver diseases ranging from fatty liver to steatohepatitis. The intricate interactions of genetic, epigenetic, and environmental factors in the development and progression of MASLD remain elusive. Here, we aimed to achieve an integrative understanding of the genomic and transcriptomic alterations throughout the progression of MASLD.

Affective dysfunction mediates the link between neuroimmune markers and the default mode network functional connectivity, and the somatic symptoms in somatic symptom disorder.

Brain Behav Immun

May 2024

Department of Psychiatry, Seoul National University Bundang Hospital, Seongnam-si, Gyeonggi-do, Republic of Korea; Department of Psychiatry, Seoul National University College of Medicine, Seoul, Republic of Korea. Electronic address:

Objective: Somatic symptom disorder (SSD) is characterized by physical symptoms and associated functional impairments that are often comorbid with depression and anxiety disorders. In this study, we explored relationships between affective symptoms and the functional connectivity of the default mode network (DMN) in SSD patients, as well as the impact of peripheral inflammation. We employed mediation analyses to investigate the potential pathways between these factors.

The physiological and pharmacological variations between men and women are known to influence drug efficacy. The objective of this study was to determine the 50% and 95% effective doses (ED and ED) of remimazolam required for i-gel supraglottic airway (ISA) insertion under remifentanil infusion without neuromuscular blocking agents (NMBAs) in both males and females. Patients aged 19-65 years, scheduled for general anesthesia using ISA, were enrolled in this study.

Objective: Precise knowledge regarding the mechanical stress applied to the intervertebral disc following each individual spine motion enables physicians and patients to understand how people with discogenic back pain should be guided in their exercises and which spine motions to specifically avoid. We created an intervertebral disc degeneration model and conducted a finite element (FE) analysis of loaded stresses following each spinal posture or motion.

Methods: A 3-dimensional FE model of intervertebral disc degeneration at L4-5 was constructed.

Article Synopsis
  • The study aimed to evaluate the effectiveness of controlled posterior condylar milling (CPCM) in minimizing tibial resection during unicompartmental knee arthroplasty for patients with medial compartment osteoarthritis.
  • Results indicated that the CPCM group had less tibial resection on average (3.6 mm) compared to the conventional group (5.2 mm), and no periprosthetic fractures occurred in the CPCM group.
  • Overall, the CPCM technique is suggested as an effective and straightforward method to achieve better alignment and gap balancing during knee surgery, with similar postoperative outcomes in terms of range of motion and pain relief.

This retrospective cross-sectional study aims to investigate the prevalence and seriousness of drug-induced nephrotoxicity and to identify clinical predictors intensifying the seriousness of nephrotoxicity. Adverse drug events (ADEs) reported to the Korean Adverse Event Reporting System Database (KAERS DB) from January 2012 to December 2021 were investigated. The association between the seriousness and the etiologic drug was estimated in reporting odds ratio (ROR) based on disproportionality analysis.
