Background: Owing to the unique characteristics of digital health interventions (DHIs), a tailored approach to economic evaluation is needed-one that is distinct from that used for pharmacotherapy. However, the absence of clear guidelines in this area is a substantial gap in the evaluation framework.

Objective: This study aims to systematically review and compare the economic evaluation literature on DHIs and pharmacotherapy for the treatment of depression.

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia with multiple clinical manifestations and complications, such as cardiovascular disease, kidney dysfunction, retinal impairment, and peripheral neuropathy. Continuous and minimally invasive glucose monitoring is essential for effective DM management. Microneedles (MNs)-based sensing platforms offer a promising solution; however, conventional polymeric MNs suffer from limited electrochemical sensitivity due to their insufficient electroactive surface area and inefficient loading of catalytic and enzymatic components.

Thermal Cross-linked Electron Transport Polymers for Suppressing Efficiency Roll-off in Green Solution-Processed Inverted OLEDs.

ACS Appl Mater Interfaces

September 2025

Organic Electronic Materials Laboratory, Department of Information Display, College of Sciences, Kyung Hee University, Seoul 02447, Republic of Korea.

Solution-processed phosphorescent inverted organic light-emitting diodes (s-IOLEDs) have garnered significant attention due to their excellent stability and high performance. However, frequently used inorganic electron transport layers usually cause exciton dissociation at the emitting layer interface, leading to low device efficiency and severe efficiency roll-off. In this work, we designed a cross-linkable triazine-grafted electron transport copolymer (PPDPT--PBCB) with a high triplet energy (3.

Wafer-scale integration of monolayer MoS residue-free support layer etching and angular strain suppression.

Nanoscale

September 2025

Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR), 2 Fusionopolis Way, Innovis #08-03, Singapore 138634, Republic of Singapore.

A crack-free and residue-free transfer technique for large-area, atomically-thin 2D transition metal dichalcogenides (TMDCs) such as MoS and WS is critical for their integration into next-generation electronic devices, either as channel materials replacing silicon or as back-end-of-line (BEOL) components in 3D-integrated nano-systems on CMOS platforms. However, cracks are frequently observed during the debonding of TMDCs from their growth substrates, and polymer or metal residues are often left behind after the removal of adhesive support layers wet etching. These issues stem from excessive angular strain accumulated during debonding and the incomplete removal of support layers due to their low solubility.

Ultrasonographic Analysis of Site-Specific Plantar Skin Thickness for Melanoma Staging and Excision.

Clin Anat

September 2025

Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seoul, South Korea.

Plantar melanomas present unique diagnostic and surgical challenges owing to substantial regional variations in skin thickness. Although the Breslow thickness remains the primary criterion for staging and surgical excision, its application on plantar melanoma is complicated by the inherent thickness of the glabrous plantar epidermis, which may lead to tumor depth overestimation. Accurate assessment of plantar skin thickness is essential for optimizing staging accuracy and refining surgical margins.

Background: Cryopyrin-associated periodic syndrome (CAPS) is an autoinflammatory disease caused by a gain-of-function mutation in the gene, which regulates inflammasome-mediated interleukin-1β (IL-1β) production. This leads to recurrent episodes of fever, rash, and arthritis, typically beginning in childhood.

Objective: To demonstrate the role of a missense mutation, c.

Design strategies for energy-harvesting photovoltaics in diverse environments.

iScience

September 2025

Energy Conversion Research Center, Electrical Materials Research Division, Korea Electrotechnology Research Institute, Changwon, Gyeongsangnam-do 51543, Republic of Korea.

Indoor photovoltaics (IPVs) are small and not optimized for versatile environments, making them environmentally sensitive. To expand the application of energy-harvesting photovoltaics, overcoming the current problems and mismatch loss is important. In this study, we found that IPVs are sensitive to changes in current density under low illuminance, and we introduced a protocol to reveal the modules resulting in the smallest standard deviation using current maps.

Transient electronics for sustainability: Emerging technologies and future directions.

Beilstein J Nanotechnol

September 2025

Department of Materials Science and Engineering, Seoul National University, Seoul, 08826 Republic of Korea.

Transient electronics are emerging as a promising class of devices designed to disappear after a defined operational period, addressing growing concerns over sustainability and long-term biocompatibility. Built from biodegradable materials that undergo hydrolysis or enzymatic degradation, these systems are particularly well suited for temporary implantable applications, such as neural monitors, wireless stimulators, and drug delivery vehicles, as well as environmentally benign electronics for soil or aquatic disposal. Despite their potential, key challenges remain in expanding the material set for diverse functionalities, achieving high-density integration for advanced operations, and enabling precise lifetime control through strategies such as protective encapsulation.

Biomechanical comparison of locking plate and pin-tension band wiring fixation for 3D-printed canine patellar fracture repair.

Front Vet Sci

August 2025

Department of Veterinary Surgery, Graduate School of Veterinary Medicine, Konkuk University, Seoul, Republic of Korea.

Introduction: The conventional pin and tension band wiring (TBW) technique remains the standard for fixation, but is frequently associated with complications such as wire breakage, loosening, and delayed healing in patellar fracture. Locking plate fixation has demonstrated superior biomechanical stability in human studies. This study aimed to compare the biomechanical performance of locking plate fixation versus TBW in canine transverse patellar fractures and to evaluate the influence of plate design on fixation strength.

Introduction: While exercise interventions are widely used for sarcopenia management, the comparative efficacy of different non-invasive treatments remains unclear. This network meta-analysis evaluated five interventions (aerobic training, resistance training, aerobi-resistance training, whole-body electrical stimulation, and electrical stimulation with protein supplementation) on body composition, physical function and quality of life in elderly sarcopenia patients.

Methods: Six databases, including PubMed, Embase and Web of Science, were systematically searched, and 22 randomized controlled trials with a total of 1062 elderly patients with sarcopenia were finally included.

Background And Aim: Mycotoxin contamination in poultry feed, particularly with aflatoxin B1 (AFB1) and ochratoxin A (OTA), poses significant threats to broiler health, meat quality, and consumer safety. Toxin binders are commonly used to mitigate these effects; however, their impact on endogenous stem cell activity and overall broiler performance remains underexplored. This study aimed to evaluate the efficacy of a commercial toxin binder in reducing AFB1 and OTA residues in broiler meat, inducing endogenous stem cell production, and improving growth and feed performance indices.
