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.

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.

Background: Human adenovirus (HAdV) is a common cause of acute respiratory disease (ARD) and has raised significant concerns within the Korean military. Here, we conducted a comprehensive epidemiological analysis of HAdV-associated ARD by evaluating its prevalence, clinical outcomes, and prognosis. Methods: We reviewed data from multiple sources, including the New Defense Medical Information System, Defense Medical Statistical Information System, Ministry of National Defense, Army Headquarters, Navy Headquarters, Air Force Headquarters, and Armed Forces Medical Command. We analyzed data of patients who underwent polymerase chain reaction (PCR) testing for respiratory viruses between January 2013 and July 2022 in all 14 Korean military hospitals. The analysis included the PCR test results, demographic characteristics, health care utilization, and prognosis including types of treatments received, incidence of pneumonia, and mortality. Results: Among the 23,830 individuals who underwent PCR testing at Korean military hospitals, 44.78% (10,670 cases) tested positive for respiratory viruses. Across all military types and ranks, HAdV was the most prevalent virus, with a total of 8,580 patients diagnosed, among HAdV, influenza virus, human metapneumovirus, human parainfluenza virus, and human respiratory syncytial virus. HAdV-infected patients exhibited higher rates of healthcare use compared to non-HAdV-infected patients, including a greater number of emergency visits (1.04 vs. 1.02) and outpatient visits (1.31 vs. 1.27), longer hospitalizations (8.14 days vs. 6.84 days), and extended stays in the intensive care unit (5.21 days vs. 3.38 days).Furthermore, HAdV-infected patients had a higher proportion of pneumonia cases (65.79%vs. 48.33%) and greater likelihood of receiving advanced treatments such as high flow nasal cannula or continuous renal replacement therapy. Conclusion Our findings indicate that HAdV posed a significant public health concern within the Korean military prior to the coronavirus disease 2019 (COVID-19) pandemic. Given the potential for a resurgence of outbreaks in the post-COVID-19 era, proactive measures, such as education, environmental improvements, and the development of HAdV vaccines, are crucial for effectively preventing future outbreaks.
