Background/aims: Despite the global burden of functional abdominal pain disorder (FAPD) and its four subtypes (irritable bowel syndrome [IBS], functional dyspepsia [FD], abdominal migraine [AM], and functional abdominal pain not otherwise specified [FAP-NOS]), studies involving an estimation of FAPD prevalence based on the Rome III or IV criteria are limited. Therefore, we aimed to estimate the prevalence of FAPD and its four subtypes.
Methods: A comprehensive literature search was conducted in PubMed/MEDLINE, Embase, Google Scholar, and the Cochrane Library.

In 2020, Y280-lineage H9N2 low pathogenic avian influenza was detected in South Korea for the first time. Active surveillance from live bird markets (LBMs) and farms revealed the continuous circulation of Y280-lineage H9N2 viruses, replacing the previously indigenous Y439-lineage and becoming dominant in South Korea. Antigenic mapping showed a substantial antigenic difference between the Y280 and Y439-lineage viruses.

Background: Due to the lack of comprehensive longitudinal studies examining the impact of long-term volatility on health issues, existing research primarily focused on income levels rather than fluctuation. Thus, we aimed to investigate the relationship between income instability and a range of physical health conditions using an extensive longitudinal dataset.
Methods: This study utilized data from the Korean Genome and Epidemiology Study (KoGES) Ansan-Anseong cohort (2001-2022), which includes valuable confounding factors such as demographic, socioeconomic, lifestyle, and clinical factors.
Background: Despite antibiotic-induced anaphylaxis being a severe allergic reaction requiring immediate care, large-scale studies examining all antibiotic subtypes remain limited. This study addresses this gap by analysing 33 antibiotic classes, along with epidemiological and regional variations.
Methods: This study utilised the world's largest pharmacovigilance database, with over 35 million individual case safety reports from 140 countries.
Insomnia may negatively impact seizure control; however, the corresponding evidence remains limited. This study analyzed the seizure risk associated with various insomnia medications using a comprehensive pharmacovigilance database and identified safe options for patients at high risk of seizures. VigiBase, a database of adverse drug reaction reports from over 140 countries, comprises 35 million reports published from 1967 to 2023.

The proposed FeTFT system integrates volatile and nonvolatile functionalities, respectively driven by optical and electrical stimuli, to emulate short-term and long-term synaptic behaviors. Leveraging persistent photoconductivity in the IGZO channel under optical excitation, the FeTFT exhibits dynamic reservoir characteristics, while HZO-induced ferroelectric polarization enables robust long-term memory for the readout layer.

Background: Drug-associated anaphylaxis is a common condition with significant risks if not promptly addressed. Yet, systematic research on the distribution of associated drugs and risk comparison across drug classes is limited. This study aims to identify frequently reported drugs and evaluate the strength of their signal detections with drug-associated anaphylaxis.

However, large-scale studies investigating this relationship remain limited. Therefore, this study aims to evaluate the signal detection between six SSRIs and serotonin syndrome, rank their relative risks, and propose practical preventive strategies.

In this study, we present the results of virological surveillance conducted between 2018 and 2023, analyzing 1970 cloacal swab samples collected from 56 bird species. We identified 74 AIVs of H3N6, H3N8, H4N6, H5N3, H7N7, H10N3, and H11N9 subtypes in Anseriformes order.

Objectives: Real-world studies on its effectiveness in patients with type 2 diabetes mellitus (T2DM) remain limited. This study aimed to evaluate the effectiveness of the live zoster vaccine in patients with T2DM more than 10 years.
Methods: In this target trial emulation study, we utilized a large-scale, nationwide cohort in South Korea, consisting of individuals aged 50 years and older with T2DM from January 1, 2012 to December 31, 2021 (n = 934 945).
Functionalization of carboranes, icosahedral boron-carbon molecular clusters, is of great interest as they have wide applications in medicinal and materials chemistry. Thus, site- and enantioselective synthesis of carboranes requires complete control of the reaction. Herein, we describe the asymmetric Rh(II)-catalyzed insertion reactions of carbenes into cage B-H bond of carboranes.
