Massive release of radioactive materials into the atmosphere occurred due to the Fukushima Daiichi Nuclear Power Station (FDNPS) accident in March 2011. The World Health Organization (WHO) and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) reported the results of dose estimation to assess the health effect of the accident and both reports state that their assessments of internal and external exposure doses contain certain uncertainties due to uncertainties inherent to the basic data. Therefore, estimation of the internal dose from tap water was conducted in this study by utilizing a database of deposition calculated by an atmospheric transfer, dispersion and deposition model (ATDM) in conjunction with the newly obtained data on the volume of daily water intake obtained by a web-based survey. The median mean and 95-percentile of thyroid equivalent doses were estimated for 1-year and 10-year children and adults in 12 municipalities in the evacuation area in Fukushima prefecture. The present mean thyroid dose estimations for 1-year children (0.4-16.2 mSv) are smaller than the corresponding values in the UNSCEAR 2013 report (1.9-49 mGy). Dose-modifying factors in the Japanese or local community are discussed.

Risk of Cancers According to the Use of Biological Agents in Patients With Radiographic Axial Spondyloarthritis: A Nationwide Population-Based Cohort Study.
J Clin Rheumatol
January 2025
From the Division of Rheumatology, Department of Internal Medicine, Yonsei University College of Medicine, Seoul, South Korea.
Objective: As the duration of use of biological disease-modifying antirheumatic drugs (bDMARDs) in patients with radiographic axial spondyloarthritis (r-axSpA) accumulates over time, long-term real-world safety data on cancer risk are needed. This study assessed the association between tumor necrosis factor inhibitors (TNFis) and interleukin 17 inhibitors (IL-17is) exposures and cancer risk in patients with r-axSpA.
Methods: From the Korean nationwide database, we assembled 41,889 patients without prior history of cancer who were diagnosed with r-axSpA from 2010 onwards.
Estimation of natural radioactivity and radiological hazards in river sediments (sand) used as building materials in South Africa.
Isotopes Environ Health Stud

School of Chemistry and Physics, University of KwaZulu-Natal, Scottsville, South Africa.
This study presents an investigation into the natural radioactivity levels of U, Th, and K using a thallium-doped sodium iodide (NaI(TI)) detector and associated radiological hazards in river sediments, specifically sand, which serves as a crucial building material in the KwaZulu-Natal Province of South Africa. The assessment aims to provide insights into potential radiological risks posed by the utilization of these sediments in construction activities. The mean activity concentrations of U, Th, and K are 145.

J Intern Med
January 2025
School of Pharmacy, Sungkyunkwan University, Suwon, South Korea.
Background: Evolving evidence suggests that patients undergoing treatment with Janus kinase inhibitors (JAKi) may face an increased risk of cardiovascular events, malignancies, and serious infections.
Objectives: We assessed cardiovascular, malignancy, and serious infection risks associated with JAKi use compared to tumor necrosis factor inhibitor (TNFi) use, which served as the active comparator, in patients with rheumatoid arthritis (RA) or ulcerative colitis (UC).
Methods: This study emulated a target trial using South Korea's nationwide claims database (2013-2023).
Four targets: an enhanced framework for guiding causal inference from observational data.
Int J Epidemiol

Observational studies play an increasingly important role in estimating causal effects of a treatment or an exposure, especially with the growing availability of routinely collected real-world data. To facilitate drawing causal inference from observational data, we introduce a conceptual framework centered around "four targets"-target estimand, target population, target trial, and target validity. We illustrate the utility of our proposed "four targets" framework with the example of buprenorphine dosing for treating opioid use disorder, explaining the rationale and process for employing the framework to guide causal thinking from observational data.

Background: Beta-lactams remain the first-line treatment of infections despite the increasing global prevalence of penicillin-resistant/non-susceptible strains. We conducted a cross-sectional household survey in a rural community in northern Vietnam in 2018-2019 to provide prevalence estimates of penicillin non-susceptible (PNSP) carriage and to investigate behavioural and environmental factors associated with PNSP colonization. The data presented will inform the design of a large trial of population-based interventions targeting inappropriate antibiotic use.
