Journal of Preventive Medicine and Public Health 2025;58(1):92-102
Objectives:
Statins are essential in the prevention of cardiovascular disease; however, their association with type 2 diabetes mellitus (T2DM) risk is concerning. We examined whether genetic susceptibility to T2DM modifies the association between regular statin use and T2DM risk.
Methods:
This study included 447 176 individuals from the UK Biobank without baseline diabetes or major cardiovascular disease. Statin use was recorded at baseline, and T2DM incidence was determined using clinical records. Polygenic risk scores (PRS) for T2DM risk were provided by the UK Biobank. Using propensity scores adjusted for age, sex, body mass index, and comorbidities, 14 831 statin users were matched with 37 060 non-users. Cox proportional hazards models were used to estimate the interaction effect of statin use and PRS on T2DM incidence, adjusting for key confounders.
Results:
In the propensity-matched cohort, 3675 of 51 891 participants developed T2DM over a mean follow-up period of 13.7 years. Within the top 5% of the PRS distribution, per 1000 person-years, the incidence of T2DM was 15.42 for statin users versus 12.18 for non-users. Among the lowest 5%, the incidence was 1.90 for statin users and 1.65 for non-users. Based on the Cox proportional hazards model, regular statin use was associated with a 1.24-fold increased T2DM risk (95% confidence interval [CI], 1.15 to 1.33). Furthermore, PRS exhibited a significant multiplicative interaction with regular statin use (odds ratio, 1.10; 95% CI, 1.02 to 1.19).
Conclusions
PRS may help identify individuals particularly susceptible to the diabetogenic effects of statins, providing a potential path for personalized cardiovascular disease management.

Korean Circulation Journal 2025;55(3):185-195
Background and Objectives:
Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment.
Methods:
A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years.
Results:
The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization.
Conclusions
For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

Annals of Laboratory Medicine 2025;45(6):609-619
Background:
Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis and lacks clinical biomarkers. Exosomes are extracellular vesicles that facilitate cell–cell communication by distributing macromolecules, such as small RNAs (smRNAs). We assessed the potential of exosome-derived small RNAs (Ex-smRNAs) as PDAC biomarkers.
Methods:
Peripheral blood was collected from 51 patients with PDAC and 15 control individuals. Exosomes were isolated using an aqueous two-phase system. Ex-smRNAs were analyzed using smRNA sequencing. smRNA-mediated target gene regulation was verified via The Cancer Genome Atlas analysis and in vitro transfection and wound-healing assays using PDAC organoids.
Results:
The total Ex-smRNA count was substantially reduced in patients with PDAC compared with that in control individuals. The levels of microRNAs (miRNAs) miR-125a-5p, miR-30e-5p, miR-16-2-3p, miR-98-5p, and the let-7 family were significantly suppressed, whereas that of miR-6731-5p was significantly elevated. Let-7c-5p and miR-98-5p were found to interact with the long non-coding RNA OLMALINC to regulate their common target genes, BACH1 and CCND1, thus controlling PDAC proliferation and migration. The expressions of CARS1-AS1 and miR-142-5p were upregulated in treatment-responsive patients.Multivariable Cox regression analyses, adjusting for potential prognostic factors such as sex, Eastern Cooperative Oncology Group performance status, and tumor size and stage, revealed that CARS1-AS1 (adjusted hazard ratio [HR] 0.33; 95% confidence interval [CI], 0.15–0.73; P = 0.0061) and miR-142-5p (adjusted HR 0.79; 95% CI, 0.61–1.01; P = 0.0581) were associated with improved overall survival.
Conclusions
We identified potential Ex-smRNA biomarkers involved in PDAC progression and prognosis that reflect key molecular alterations in PDAC and may serve as clinically relevant biomarkers for disease monitoring.

Journal of Korean Medical Science 2024;39(24):e191-
Background:
Currently, non-vitamin K-antagonist oral anticoagulant (NOAC) monotherapy has been suggested as the optimal antithrombotic therapy for atrial fibrillation (AF) beyond one year after coronary revascularization. The aim of this study was to compare the outcomes between NOAC monotherapy and NOAC plus antiplatelet combination therapy using realworld data.
Methods:
Between 2015 and 2020, patients with AF who had received NOACs beyond one year after coronary revascularization were enrolled from Korean national insurance data. We emulated a pragmatic sequence of trials between the NOAC monotherapy and the antiplatelet combination therapy followed by propensity score matching. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCEs), a composite of all-cause death, myocardial infarction, and stroke.
Results:
Among 206,407 person-trials from 4,465 individuals, we compared 3,275 pairs of the monotherapy and the matched combination therapy. During a median follow-up of 1.24 years, the incidence rate of MACCE was 19.4% and 20.0% per patient-year in the monotherapy group and the antiplatelet combination group, respectively (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.88–1.05; P = 0.422). Compared with the antiplatelet combination group, the monotherapy group had a significantly lower incidence rate of major bleeding, defined as intracranial bleeding or gastrointestinal bleeding requiring hospitalization (2.8% vs. 3.6% per patient-year; HR, 0.78; 95% CI, 0.62–0.97; P = 0.024).
Conclusion
As an antithrombotic therapy for AF beyond one year after coronary revascularization, NOAC monotherapy was associated with a similar risk of MACCE and a lower risk of major bleeding compared to NOAC plus antiplatelet combination therapy.

A 67-year-old female patient was admitted with posterior neck pain, motor weakness in the right upper extremity, and gait disorder.The patient had a history of Sjogren’s syndrome but no history of rheumatoid arthritis or other specific histories. The finding of cervical myelopathy was confirmed by cervical magnetic resonance imaging. As atlanto-axial instability was observed on the cervical radiography, both posterior fusion and laminectomy were performed. After surgery, the pain decreased and neurological symptoms improved immediately. Thus, in Sjogren’s syndrome, we should pay attention to the presence of atlanto-axial instability in the cervical radiograph.
