Stereotactic body radiation therapy for hepatocellular carcinoma: 2026 expert consensus-based practical recommendation of the Korean Liver Cancer Association

Stereotactic body radiation therapy (SBRT) is a noninvasive, high-precision radiation technique that delivers a high dose to the tumor in a limited number of fractions, typically five or fewer, and is increasingly used as a curative-intent option for hepatocellular carcinoma (HCC...

Sex and Mortality Among Patients with Papillary Thyroid Cancer

Importance Unlike patient age, which has been a well-established and routinely used primary biological prognostic factor in the risk stratification of papillary thyroid cancer (PTC), the prognostic value of patient sex remains controversial in this common endocrine malignant neop...

Prognostic implications of the duration of continuous kidney replacement therapy in 3-month survivors of acute kidney injury: findings from the LINKA cohort

The duration of continuous kidney replacement therapy (CKRT) represents a complex clinical surrogate reflecting the severity of systemic illness, the rate of metabolic recovery, and clinical decision-making regarding treatment discontinuation. The effect of CKRT duration on long-...

Trastuzumab plus nivolumab with gemcitabine and cisplatin as first-line therapy for HER2-positive unresectable biliary tract cancer: a phase 1b/2 trial

Biliary tract cancers (BTCs) are associated with poor outcomes despite recent incorporation of immune checkpoint inhibitors into first-line chemotherapy. Human epidermal growth factor receptor 2 (HER2) overexpression or amplification defines a therapeutically targetable subset of...

Institutional Variation in MRI Utilization After Prostatectomy for Prostate Cancer: A Multicenter Study

Background/Objectives: Healthcare utilization may vary because of institutional practice patterns and policy context. This study aimed to evaluate institutional variation and clinical factors associated with repeated MRI examinations after prostatectomy and to explore whether cum...

Oxygen reserve index-based positive end-expiratory pressure allocation and end-of-surgery lung ultrasound findings during robot-assisted laparoscopic prostatectomy: a prospective randomized controlled trial

Pneumoperitoneum and steep Trendelenburg positioning during robot-assisted laparoscopic prostatectomy (RALP) promote lung derecruitment. We evaluated whether a prespecified oxygen reserve index (ORI)-based positive end-expiratory pressure (PEEP) allocation strategy reduced the st...

Success criteria for dental implants over the past 48 years

More than a century has passed since dental implants were first introduced and documented in the English literature.As the Korean Academy of Implant Dentistry (KAID) celebrates its 50th anniversary, there is a critical need to clarify the dental implant success criteria establish...

PCSK9 Inhibition Attenuates Renal Oxidative Stress and Lipotoxicity in Diabetic Kidney Disease in Association with AMPK Activation

Renal lipotoxicity and oxidative stress are major contributors to diabetic kidney disease (DKD), but the role of proprotein convertase subtilisin/kexin type 9 (PCSK9) and its relationship with AMP-activated protein kinase (AMPK) signaling remain unclear. We investigated the effec...

Venoarterial extracorporeal membrane oxygenation for chemotherapy-induced neutropenic septic shock in children: a single-center experience

Abstract Background Venoarterial extracorporeal membrane oxygenation (VA ECMO) in pediatric septic shock patients remains controversial, particularly in children with neutropenia, because of concerns about bleeding, infection, and poor prognosis. Chemotherapy-induced neutropenia,...

Femtosecond X-ray Tracking of Oxygen Vacancy-Driven Shallow-to-Deep Trap Transition and Its Impact on Charge Carrier Dynamics in Blue TiO2

Abstract Oxygen vacancies introduced by self-reduction are central to the enhanced light absorption and photocatalytic activity of blue TiO2, yet how they reshape the ultrafast dynamics of photogenerated charge carriers has remained unresolved. Here, we directly track these dynam...

Metabolic health, obesity, and prognosis in chronic obstructive pulmonary disease

Metabolic syndrome is a common comorbidity in chronic obstructive pulmonary disease (COPD), yet its long-term impact on survival and exacerbations remains controversial. We investigated whether metabolic health status and body mass index (BMI) influence mortality and the rate of...

Direct Observation of Radical‐Mediated Oxide‐to‐Alloy Transformation in Solution Under Pulsed Laser Irradiation

ABSTRACT Pulsed laser irradiation (PLI) is widely used to synthesize metal‐based functional materials in solution, yet the molecular‐level mechanism by which a laser pulse reduces a metal‐oxide precursor has remained unresolved. Here we combine time‐resolved in situ x‐ray absorpt...

Remimazolam Versus Dexmedetomidine for Monitored Anesthesia Care in Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation: A Randomized Clinical Trial

Background/Objectives: Monitored anesthesia care is increasingly used for transfemoral transcatheter aortic valve implantation (tf-TAVI), but the optimal sedative regimen remains uncertain. We compared remimazolam with dexmedetomidine during tf-TAVI. Methods: In this single-cente...

Expanding the spectrum of post-HSCT hemolysis: from passenger lymphocyte syndrome to host- and graft-associated alloimmune hemolytic anemia

Abstract Immune-mediated alloimmunization and hemolytic anemia can complicate ABO-incompatible hematopoietic stem cell transplantation (HSCT). After major ABO-incompatible HSCT, clinical manifestations may include pure red cell aplasia and delayed hemolysis. Passenger lymphocyte...

Artificial intelligence in upper gastrointestinal endoscopy: what detection rates cannot tell us

Impact of real-time artificial intelligence integration on detection of gastric lesions: an exploratory single-center before-and-after study using low-definition routine endoscopyPost hoc analysis indicates that real-time AI modestly improves detection of subcentimeter (≤0.5 cm)...

Three-Year Outcomes of Drug-Eluting Stents, Drug-Coated Balloons, and Non-Drug-Eluting Devices in Native Femoropopliteal Artery Disease: An Analysis of the K-VIS ELLA Registry

Background: Although drug-eluting devices have demonstrated improved efficacy in femoropopliteal artery (FPA) disease, evidence on their long-term clinical outcomes in realworld practice remains limited.Methods: Using data from the multicenter Korean Vascular Intervention Society...

Adolescent arm wrestling–related medial epicondyle fractures: carrying angle and body mass index as associated anatomic and anthropometric factors

Medial epicondyle fractures during arm wrestling are rare but potentially debilitating injuries in adolescents, with previous reports limited to small case series of fewer than 10 patients. The anatomic and anthropometric factors predisposing adolescents to this injury pattern re...

Dental age estimation and assessment of the 18-year threshold using the third molar maturity index and dental development stages in a Korean population

Third molar development is widely used for forensic age estimation and for classifying individuals as adults or minors based on the legal age threshold. This study aimed to evaluate the applicability of Cameriere’s third molar maturity index and three stage-based indicators, Demi...

Comparing the Efficacy and Tolerability of Two 0.3% Hyaluronic Acid Eye Drop Preparations for Dry Eye Disease: a Randomized Trial

Purpose: To evaluate the efficacy and tolerability of a new 0.3% non-preservative low viscosity hyaluronic acid (HA) preparation (Kynex 3), compared to the same concentration of HA (Hyalein Mini 0.3%) for the treatment of dry eye disease. Methods: A prospective, single-center, ra...

Extended treatment duration and recurrence in successfully treated drug-susceptible pulmonary tuberculosis with cavity on chest radiograph

Background Cavity on chest radiograph is recognized as an independent risk factor for recurrence in pulmonary tuberculosis (TB), but evidence supporting extended treatment in these patients remains limited, particularly in real-world data from Korea. Methods We performed a retros...
