Microfocused ultrasound (MFU) and (MRF) are non-invasive modalities widely used for skin rejuvenation and are often combined with injectables, including neuromodulators and soft tissue fillers. However, large-scale, long-term safety data on such combination therapies are lacking. To address this gap, we conducted a retrospective chart review at two private practice dermatology clinics in South Korea from June 2005 to December 2023.

Background: The phase 3 open-label KEYNOTE-426 study demonstrated that first-line pembrolizumab plus axitinib improved overall survival (OS) and progression-free survival (PFS) versus sunitinib for metastatic renal cell carcinoma (mRCC) in a global population. This subgroup analysis investigated the efficacy and safety of pembrolizumab-axitinib versus sunitinib in patients enrolled in KEYNOTE-426 in East Asia (Japan, South Korea, and Taiwan).

Methods: Adults with clear cell mRCC were randomly assigned 1:1 to receive intravenous pembrolizumab 200 mg every 3 weeks with oral axitinib 5 mg twice daily or oral sunitinib 50 mg once daily (4 weeks on/2 weeks off).

Rett syndrome (RTT) is a neurological disorder caused by a mutation in the X-linked methyl-CpG binding protein 2 (MECP2), leading to cognitive and motor skill regression. Therapeutic strategies aimed at increasing brain-derived neurotrophic factor (BDNF) levels have been reported; however, BDNF treatment has limitations, including the inability to penetrate the blood-brain barrier, a short half-life, and potential for adverse effects when administered via intrathecal injection, necessitating novel therapeutic approaches. In this study, we focused on the adenosine A receptor (AR), which modulates BDNF and its downstream pathways, and investigated the therapeutic potential of CGS21680, an AR agonist, through in vitro and in vivo studies using R106W RTT model.

Background/purpose: This study aimed to evaluate the initial implementation of competency-based medical education (CBME) through entrustable professional activities (EPAs) in Taiwan dental education, focusing on tooth extraction EPAs across undergraduate year (UGY), postgraduate year (PGY), and oral and maxillofacial surgery-residency (OS-R) levels.

Materials And Methods: Using the Delphi method, an advisory team developed and validated three levels of trial EPAs, which were implemented through the Emyway platform. A structured questionnaire was used to evaluate teachers' and students' experiences and satisfaction with Emyway and the EPAs.
