Neuropathic pain markedly impairs quality of life and imposes a substantial socioeconomic burden, while available treatments often provide only partial relief and are limited by safety concerns. The Neuropathic Pain Special Interest Group of the International Association for the Study of Pain (NeuPSIG-IASP) first published pharmacologic recommendations in 2007, followed by a major update in 2015 and a new guideline in 2025. This narrative review specifically compares the 2015 and 2025 NeuPSIG-IASP guidelines, outlining key methodological changes and therapeutic shifts. The 2025 guideline is based on a larger, more rigorous meta-analysis, maintains α2δ-ligands (adds mirogabalin), serotonin-noradrenaline reuptake inhibitors, and tricyclic antidepressants as first-line drugs, downgrades tramadol into the opioid third-line group. It also introduces high-frequency motor-cortex repetitive transcranial magnetic stimulation as a weakly recommended third-line option and discusses implications for Korean clinical practice.

Objective: Disasters such as pandemics and natural catastrophes cause significant psychological distress, increasing the risk of depression, anxiety, and post-traumatic stress disorder (PTSD). This review aimed to evaluate the effectiveness of remote mental health interventions, such as telepsychiatry, online cognitive behavioral therapy (CBT), mobile applications, and artificial intelligence (AI)-based tools, during disasters. Methods: A comprehensive literature search was conducted using international databases (PubMed, EMBASE, PsycINFO, Web of Science, Scopus, CINAHL) and Korean domestic databases (KISS, RISS, DBpia, KMbase, KoreaMed). Studies published between January 2010 and February 2025 were screened following the PRISMA 2020 guidelines. Two board-certified psychiatrists independently reviewed titles, abstracts, and full texts. Peer-reviewed articles and relevant grey literature, including government manuals and expert guidelines, were included. Results: A total of 147 studies were synthesized, including randomized controlled trials, meta-analyses, observational studies, and policy documents. Evidence showed that remote interventions effectively reduced symptoms of depression, anxiety, and PTSD. Online CBT was beneficial for mild to moderate distress; mobile apps facilitated psychoeducation and symptom tracking; and telepsychiatry ensured care continuity, especially in underserved areas. AI tools showed promise in screening and triage but require better clinical integration. Effectiveness was highest when interventions were implemented early, integrated within stepped-care models, and guided by trained professionals. Conclusion Remote mental health interventions are practical and effective tools for bridging mental health care gaps during disasters. To ensure sustainability, these interventions should be integrated into national disaster mental health frameworks, accompanied by adequate funding, clinician training, legal safeguards, and cultural adaptation.

Triple-negative breast cancer (TNBC) is an aggressive cancer subtype lacking targeted therapies and is characterized by highrecurrence rates and poor prognosis. Recent advances in targeting DNA damage response (DDR) pathways using poly (ADP‒ri-bose) polymerase (PARP) inhibitors offer promising therapeutic strategies, especially for TNBC patients with BRCA1/2 mutations.This study reports the development and characterization of ART-446, a novel and selective CHK2 inhibitor. ART-446 showed potent activity against TNBC, regardless of BRCA deficiency, and it also reversed PARP inhibitor resistance. ART-446 potentlyinhibited CHK2 (IC50 : 9.06 nM) with high selectivity over other kinases; it synergized with the PARP inhibitor olaparib, enhancingDNA damage, inducing G2/M cell cycle arrest, and promoting apoptosis in both BRCA-mutant and wild-type TNBC cells. Mechanistic analyses revealed that ART-446 sensitized BRCA mutant and WT cells to PARP inhibitors by impairing DNA repair and increasing the accumulation of DNA damage. Importantly, ART-446 disrupted both homologous recombination and nonhomologous end-joining repair pathways, addressing a key limitation of PARP inhibitor monotherapy—resistance in BRCA-proficient cancers.In vivo, the combination of ART-446 and olaparib significantly reduced tumor growth in TNBC xenograft models without noticeable toxicity. The combined treatment increased DNA damage signaling, as evidenced by elevated γH2AX levels, and enhanced the sensitivity of BRCA2-deficient cells to ART-446. These findings underscore the potential of ART-446 to exploit DNA repair deficiencies and overcome resistance mechanisms associated with PARP inhibitors. By addressing the limitations of current treatments and expanding the utility of PARP inhibitors, ART-446 represents a promising candidate for DDR-targeted therapies, offering a novel approach to improve the outcomes of patients with TNBC.
