Although the activities of the Committee for Health Workforce Projections have concluded, methodological debates persist. This opinion analyzes the technical and policy limitations of previous workforce estimations and proposes an academic direction for future governance to ensure scientific validity.Current concepts: Long-term workforce planning requires “projection” based on conditional scenarios, which is conceptually distinct from short-term “forecasts” or probabilistic “predictions.” While countries such as the United States and Japan employ simulation models that incorporate dynamic policy variables, Korea’s recent approach relied on inappropriate time-series models and lacked adequate data processing and preparation.Discussion and conclusion: This opinion identifies critical failures in data readiness, model selection, and verification processes. To address these limitations, we propose establishing a permanent technical working group that is institutionally separate from political bodies to ensure rigorous methodological validation. Essential reforms include the creation of a standardized analytical dataset and the adoption of dynamic models capable of simulating policy interventions rather than merely extrapolating past trends. Ultimately, workforce estimation must evolve into a rational policy tool grounded in long-term social deliberation.

Purpose: Androgen signaling is associated with various secondary cancer, which could be promising for potential treatment using androgen deprivation therapy (ADT). This study investigated whether ADT use was associated with secondary cancers other than prostate cancer in a nationwide population-based cohort. Materials and Methods: A total, 278,434 men with newly diagnosed prostate cancer between January 1, 2002 and December 31, 2017 were identified. After applying the exclusion criteria, 170,416 men were enrolled. The study cohort was divided into ADT and non-ADT groups by individual matching followed by propensity score matching (PSM). Study outcomes were incidence of all male cancers. Cox proportional hazard regression models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of events. Results: During a median follow-up of 4.5 years, a total of 11,059 deaths (6,329 in the ADT group and 4,730 in the non-ADT group) after PSM were found. After PSM, the overall all-cause of secondary cancer incidence risk of the ADT group was higher than that of the non-ADT group (HR: 1.312, 95% CI: 1.23–1.36; adjusted HR: 1.344, 95% CI: 1.29–1.40). The ADT group showed higher risk of overall brain and other central nervous system (CNS) cancer-specific incidence than the non-ADT group (adjusted HR: 1.648, 95% CI: 1.21–2.24). The ADT group showed lower risks of overall cancer-specific incidence for stomach, colon/rectum, liver/inflammatory bowel disease (IBD), gall bladder/extrahepatic bile duct, lung, bladder, and kidney cancers than the non-ADT group. When the duration of ADT was more than 2 years of ADT, the ADT group showed higher risk of cancer-specific incidence for brain and other CNS cancers but lower risk of cancer-specific incidence for liver/IBD and lung cancers than the non-ADT group. Conclusions This study demonstrates that ADT could affect cancer-specific incidence for various cancers.

We analyzed the publication and submission statuses of Korean medical journals from 2010 to 2024, amidst challenges impacting researchers. Data from 58 domestic journals identified through the 2023 JCR database were used to assess publication status, while data from the Journal of Korean Medical Science (JKMS) were utilized to examine submission status.The proportion of published original articles by domestic authors decreased by 3% in 2024 compared to 2023. Submissions to JKMS also decreased overall, except for slight increases in May and October 2024. In contrast, international submissions to JKMS showed consistent growth, surpassing the 15-year average, reflecting growing global interest. Addressing issues, including medical school admission policies and the lingering effects of coronavirus disease 2019, is vital to ensure a sustainable and thriving medical research environment in Korea.

Background: The coronavirus disease 2019 (COVID-19) pandemic has altered daily behavioral patterns based on government healthcare policies, including consumption and movement patterns. We aimed to examine the extent to which changes in the government's healthcare policy have affected people's lives, primarily focusing on changes in consumption and population movements. Methods: We collected consumption data using weekly credit card transaction data from the Hana Card Corporation and population mobility data using mobile phone data from SK Telecom in Seoul, South Korea. Interrupted time-series analysis was used to calculate the relative risk ratio and perform the intervention effects when government healthcare policy changes. Results: We found that leisure and outside movements were the most immediately affected by changes in government healthcare policies. It took over 2 years and 11 months, respectively, for these sectors to return to their pre-COVID-19 routines. Conclusion Enhancing healthcare policies presents advantages and disadvantages.Although such policies help prevent the spread of COVID-19, they also reduce consumption and mobility, extending the time needed to return to pre-COVID-19 levels. Government healthcare policymakers should consider not only disease prevention but also the impact of these policies on social behaviors, economic activity, and mobility.
