Sodium-glucose co-transporter 2 inhibitors, such as enavogliflozin, offer promising metabolic benefits for patients with type 2 diabetes (T2D), including glycemic control and improved cardiac function. Despite the clinical evidence, real-world evidence is needed to validate their safety and effectiveness. This study aims to evaluate the effects of weight loss and safety of enavogliflozin administration in patients with T2D in a real-world clinical setting over 24 weeks.

Background And Aims: We investigated associations between body mass index (BMI) and hepatocellular carcinoma (HCC) in patients with hepatitis B (HBV) C (HCV) virus infection, alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), and liver cirrhosis (LC).

Methods: We followed 350,608 Korean patients with liver disease who underwent routine health examinations from 2003-2006 until December 2018 via national hospital discharge records. Multivariable adjusted hazard ratios (HRs) per 5-kg/m2 BMI increase (BMI ≥25 kg/m2) for HCC risk were calculated using Cox models.

The LI-RADS Ultrasound Surveillance algorithm was updated in 2024, incorporating alpha-fetoprotein (AFP) and visualization score of VIS-C into management recommendations after nonpositive results. This study aimed to compare the diagnostic performance of LI-RADS Ultrasound Surveillance version 2017 (v2017) and version 2024 (v2024) for hepatocellular carcinoma (HCC) detection in at-risk patients and to identify predictors of VIS-C on follow-up surveillance examinations. This retrospective analysis included 407 patients (median age, 56 years; 230 male, 177 female) with cirrhosis who underwent rounds of semi-annual surveillance ultrasound as part of a prospective trial from November 2011 to December 2012.

The increasing demand for Li-ion batteries across various energy storage applications underscores the urgent need for environmentally friendly and efficient direct recycling strategies to address the issue of substantial cathode waste. Diverse reducing agents for Li supplements, such as quinone molecules, have been considered to homogenize the Li distribution in the cathode materials obtained after cycling; however, the detailed reaction mechanism is still unknown. Herein, the ideal electrochemical potential factor and reaction mechanism of the redox mediator 3,5-di-tert-butyl-o-benzoquinone (DTBQ) for the chemical relithiation of high-Ni-layered cathodes are elucidated.

Background: There is a paucity of data regarding drug-coated balloon (DCB) treatment in the context of left main (LM) true bifurcation lesions.

Aims: The aim of this study was to evaluate the safety and efficacy of DCB-based treatment for unprotected LM true bifurcation lesions.

Methods: A total of 39 patients with LM true bifurcation lesion (Medina: 1,1,1/0,1,1/1,0,1) who were successfully treated with DCB alone or in combination with drug-eluting stent (DES) were retrospectively enrolled into the DCB-based group.
