- Abstract
Objective: To investigate the long-term prognostic implications of contrast-induced acute kidney injury (CI-AKI) with transient or persistent renal dysfunction in acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI).Design: A retrospective observational registry study.Setting: Clinical follow-up after PCI. Patients and methods A total of 1041 PCI-treated AMI patients from the Infarction Prognosis Study registry. CI-AKI was defined as an increase in serum creatinine (>25% or >0.5 mg/dl (>44.2 μmol/l)) within 2 days after PCI. Main outcome measures Two-year cumulative event rate of all-cause death or renal failure requiring dialysis.Results: CI-AKI was observed in 148 patients (14.2%). Patients with CI-AKI had a higher rate of death or dialysis (25.4% vs. 6.3%, p<0.001) at 2 years compared with patients without CI-AKI. CI-AKI was an important independent predictor of death or dialysis (HR 2.76, 95% CI 1.61 to 4.73, p<0.001) Persistent renal dysfunction after CI-AKI was documented in 68 patients (45.9%). Patients with transient renal dysfunction showed a lower 2-year event rate of death or dialysis compared with those with persistent renal dysfunction (17.9% vs. 34.1%, p=0.013); however, they showed a higher event rate compared with those without CI-AKI (17.9% vs. 6.3%, p<0.001).Conclusion: Transient and persistent renal dysfunction after CI-AKI was associated with increased short and long-term mortality and morbidity in AMI patients treated by PCI. Better preventive strategies are needed to improve clinical outcomes in AMI patients at high risk of developing CI-AKI. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Many studies have demonstrated that late or very late thrombosis after drug-eluting stent (DES) implantation may be related with incomplete neointimal coverage. We investigated long-term (≥2 years) results of neointimal coverage following sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES) implantation using optical coherence tomography (OCT). A follow-up angiography with OCT examination was performed in 29 patients with 32 lesions for more than 2 years (group 1; 1,066 ± 381 days) and 101 patients with 104 lesions at 9 months (group 2; 273 ± 33 days) after the index procedure. The status of neointimal coverage and stent apposition was evaluated. The number of stents with completely covered struts was higher (25.0% in group 1 vs. 13.5% in group 2, P = 0.12). The percentage of uncovered struts (5.4 ± 7.5% in group 1 vs. 8.5 ± 11.6% in group 2, P = 0.19) and that of malapposed strut (0.5 ± 1.4% vs. 1.5 ± 4.2%, respectively, P = 0.19) were lower in group 1. While the percentage of uncovered and malapposed struts were quite similar in the PES groups between the two groups (P = 0.54 and 0.65, respectively), there were lower trends in the percentage of uncovered and malapposed struts in the SES group (P = 0.09 and 0.09, respectively). In conclusion, incomplete neointimal coverage was still observed in a majority of DESs and considerable struts were not covered with neointima even at more than 2 years after DES implantation. The pattern of neointimal coverage between 9-month and 2-year appeared to be somewhat different between PES and SES. [ABSTRACT FROM AUTHOR]

This study aims to identify the therapeutic effect of Korean red ginseng (KRG) on the expression of inflammatory cytokines in rats with focal cerebral ischemia/reperfusion injury. Adult male Sprague-Dawley rats were subjected to transient middle cerebral artery occlusion (tMCAO) for two hours. They were fed KRG extract (100 mg/kg/day per orally) or saline after reperfusion. Tests for neurological deficits, using the modified neurologic severity score and the corner turn test, were performed before the ischemic event, and one, three, and seven days after tMCAO. Serum levels of cytokines were measured three and seven days after the operation, using enzyme-linked immunosorbent assays. The infarct volume was assessed after seven days by staining brain tissue with 2% 2, 3, 5-triphenyltetrazolium chloride. Oral administration of KRG significantly reduced the infarct volumes and rapidly improved neurological deficits. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and IL-6 were higher in tMCAO-operated rats than in the sham-operated rats. These changes were attenuated by daily KRG intake for seven days. Serum IL-10 levels were significantly increased in KRG-fed rats, as compared to sham-operated and saline-fed rats. Our results suggested that KRG provides neuroprotection for rats with focal cerebral ischemia/reperfusion injury. This neuroprotection may be due to raised IL-10 expression and a reduction in the serum levels of TNF-α, IL-1β, and IL-6. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: To compare the efficacy of subintimal angioplasty combined with primary stenting to intraluminal angioplasty with stenting for revascularization of long (>10 cm) femoropopliteal arterial occlusions.Methods: Baseline characteristics and outcomes of 52 patients (40 men; mean age 65.6+/-9.7 years) with superficial femoral artery (SFA) occlusions in 61 limbs (mean occlusion length 22.7+/-9.9 cm) treated with subintimal angioplasty and primary stenting were compared with a 54-patient control group (46 men; mean age 64.8+/-8.2 years) from our registry database who had intraluminal angioplasty with stenting in 60 limbs (mean occlusion length 22.0+/-8.5 cm).Results: All baseline clinical and angiographic characteristics showed no differences. In all patients, at least 1 self-expanding nitinol stent was implanted. Subintimal angioplasty was successful in 58 (95.1%) of 61 limbs, whereas technical success for the conventional approach was 86.7% (52/60 limbs; p = 0.11). In both groups, there were no major complications requiring surgery. Primary patency at 12 months for successful cases was 76.4% for subintimal angioplasty and 59.2% for conventional angioplasty (p = 0.06); on an intention-to-treat basis, including technical failures, the rates were 72.4% and 50.9%, respectively (p = 0.02).Conclusion: Subintimal angioplasty combined with stenting was feasible, with a high technical success rate and better short and midterm results for revascularization of long femoropopliteal occlusions than the conventional intraluminal approach.

- Abstract
Eating disorders are an important cause of physical and psychosocial morbidity in adolescent girls and young adult women. Although eating disorders have many medical complications, it is unclear which are responsible for the increased mortality. It should be emphasised that a number of different pathological processes are likely to be involved. Patients with eating disorders should be monitored carefully and should remain hospitalised. This can allow immediate emergency treatment to be performed when necessary because they could have a further cardiac arrest. A case of cardiac arrest is reported that was caused by gastric dilatation and elevated abdominal pressure, which were brought on by binge eating in a patient without intestinal obstruction.

- Abstract
Background: The presence of dedicated intensive care unit (ICU) physicians is associated with reduced ICU mortality. However, the information available on the role of cardiac intensivists in cardiac ICUs (CICUs) is limited. Therefore, we investigated the association of cardiac intensivist-directed care with clinical outcomes in adult patients admitted to the CICU., Methods: In this retrospective study, we extracted data from the SMART-RESCUE registry, a multicenter, retrospective, and prospective registry of patients presenting with cardiogenic shock. Overall, 1,247 patients with CS were enrolled, between January 2014 and December 2018, from 12 tertiary centers in Korea. The patients were categorized into two groups based on the involvement of a cardiac intensivist in their care. The primary outcome was in-hospital mortality rate., Results: The all-cause mortality rate was 33.6%. The in-hospital mortality rate was lower (25.4%) in the cardiac intensivist group than in the non-cardiac intensivist group (40.1%). Cardiac mortality rates were 20.5% and 35.4% in the cardiac intensivist and non-cardiac intensivist groups, respectively. In patients undergoing extracorporeal membrane oxygenation, the mortality rate at centers with cardiac intensivists was 38.0%, whereas that at centers without cardiac intensivists was 62.2%. The dopamine use was lower, norepinephrine use was higher, and vasoactive-inotropic score was lower in the cardiac intensivist group than in the non-cardiac intensivist group., Conclusions: Involvement of a cardiac intensivist in CICU patient care was associated with a reduction in in-hospital mortality rate and the administration of a low dose of vasopressors and inotropes according to the cardiogenic shock guidelines., Competing Interests: Declarations. Ethics approval and consent to participate: The study protocol was approved by the “Samsung Medical Center” Ethics Committee (approval no. 2016-03-130, April 06, 2016) and the local ethics committees of all the study centers.

- Abstract
Background: The role of transitioning from short dual antiplatelet therapy (DAPT) to potent P2Y12 inhibitor monotherapy in patients with acute coronary syndrome (ACS) undergoing drug-eluting stent (DES) implantation remains inconclusive., Purpose: To compare the effects of de-escalating DAPT to ticagrelor monotherapy versus standard DAPT from randomized clinical trials in patients with ACS., Data Sources: PubMed, EMBASE, Scopus, and ClinicalTrials.gov from inception to 12 December 2024., Study Selection: Randomized clinical trials comparing de-escalating DAPT to ticagrelor monotherapy versus ticagrelor-based standard DAPT for 12 months, specifically in patients with ACS undergoing DES implantation., Data Extraction: The coprimary end points were an ischemic end point (composite of death, nonprocedural [spontaneous] myocardial infarction, or stroke) and a bleeding end point (Bleeding Academic Research Consortium types 3 or 5 bleeding)., Data Synthesis: Individual patient data were obtained from 3 trials (TICO [Ticagrelor Monotherapy After 3 Months in the Patients Treated With New Generation Sirolimus-Eluting Stent for Acute Coronary Syndrome], T-PASS [Ticagrelor Monotherapy in Patients Treated With New-Generation Drug-Eluting Stents for Acute Coronary Syndrome], and ULTIMATE-DAPT [Ticagrelor alone versus ticagrelor plus aspirin from month 1 to month 12 after percutaneous coronary intervention in patients with acute coronary syndromes]), including 9130 randomized patients with ACS; 3132 had ST-segment elevation myocardial infarction (STEMI), 3023 had non-STEMI (NSTEMI), and 2975 had unstable angina. The rate of the primary ischemic end point was not different between the ticagrelor monotherapy and standard DAPT groups (1.7% vs. 2.1%; hazard ratio [HR], 0.85 [95% CI, 0.63 to 1.16]). The rate of the primary bleeding end point was lower in the ticagrelor monotherapy group (0.8% vs. 2.5%; HR, 0.30 [CI, 0.21 to 0.45]). These findings were consistent in patients with STEMI, NSTEMI, and unstable angina., Limitation: Other de-escalation strategies for modulating antiplatelet therapy were not included., Conclusion: In patients with ACS undergoing DES implantation, de-escalating DAPT to ticagrelor monotherapy was associated with a lower risk for major bleeding compared with standard DAPT, without an increase in ischemic events, regardless of the type of ACS., Primary Funding Source: None.

- Abstract
Polymer-embedded metal nanoparticles are in great demand owing to their unique features, leading to their use in various important applications, including catalysis reactions. However, particle sintering and aggregation are serious drawbacks, resulting in a drastic loss of catalytic activity and recyclability. Herein, a reduction-immobilizing strategy of polymer-embedded sub-2 nm Cu nanoparticles offered highly controlled distribution and nanoparticle size within polymer structures with high fidelity. This work sheds light on the high catalytic performance of nanoparticles that rely on their ultrasmall size and uniform distribution in polymer structures, generating more active sites that result in high efficiency reduction of organic compounds. A catalysis study was carried out for the hydrogenation of nitro compounds, achieving nearly 100% reduction in an extremely short time and remaining stable after 15 consecutive cycles. Furthermore, the catalytic mechanism was demonstrated by density functional theory (DFT) calculations. Notably, the discovery of this facile strategy may enable the remarkable cutting-edge design of catalyst materials with promising performance and stability.

- Abstract
Importance: In patients with atherosclerotic cardiovascular disease (ASCVD), intensive lowering of low-density lipoprotein (LDL) cholesterol levels with high-intensity statins is generally recommended. However, alternative approaches considering statin-related adverse effects and intolerance are needed., Objective: To compare the long-term efficacy and safety of an alternative LDL cholesterol-lowering strategy vs high-intensity statin strategy in patients with ASCVD in randomized clinical trials., Data Sources: PubMed, Embase, and other websites (ClinicalTrials.gov, European Society of Cardiology, tctMD) were systematically searched from inception to April 19, 2024., Study Selection: Randomized clinical trials comparing an alternative LDL cholesterol-lowering strategy vs a high-intensity statin strategy in patients with ASCVD, with presence of cardiovascular events as end points., Data Extraction and Synthesis: Individual patient data were obtained from randomized clinical trials that met the prespecified eligibility criteria: RACING (Randomized Comparison of Efficacy and Safety of Lipid-Lowering With Statin Monotherapy vs Statin/Ezetimibe Combination for High-Risk Cardiovascular Disease) and LODESTAR (Low-Density Lipoprotein Cholesterol-Targeting Statin Therapy vs Intensity-Based Statin Therapy in Patients With Coronary Artery Disease). The moderate-intensity statin with ezetimibe combination therapy in the RACING trial and the treat-to-target strategy in the LODESTAR trial were classified as alternative LDL cholesterol-lowering strategies. The primary analysis was based on a 1-stage approach., Main Outcomes and Measures: The primary end point was a 3-year composite of all-cause death, myocardial infarction, stroke, or coronary revascularization. The secondary end points comprised clinical efficacy and safety end points., Results: Individual patient data from 2 trials including 8180 patients with ASCVD (mean [SD] age, 64.5 [9.8] years; 2182 [26.7%] female; 5998 male [73.3%]) were analyzed. The rate of the primary end point did not differ between the alternative strategy and high-intensity statin strategy groups (7.5% [304 of 4094] vs 7.7% [310 of 4086]; hazard ratio, 0.98; 95% CI, 0.84-1.15; P = .82). The mean (SD) LDL cholesterol level during treatment was 64.8 (19.0) mg/dL in the alternative strategy group and 68.5 (20.7) mg/dL in the high-intensity statin strategy group (P < .001). The alternative strategy group had a lower rate of new-onset diabetes (10.2% [271 of 2658] vs 11.9% [316 of 2656]; P = .047), initiation of antidiabetic medication for new-onset diabetes (6.5% [173 of 2658] vs 8.2% [217 of 2656]; P = .02), and intolerance-related discontinuation or dose reduction of assigned therapy (4.0% [163 of 4094] vs 6.7% [273 of 4086]; P < .001)., Conclusions and Relevance: Results of this systematic review and individual patient data meta-analysis suggest that compared with a high-intensity statin strategy, the alternative LDL cholesterol-lowering strategy demonstrated comparable efficacy regarding 3-year death or cardiovascular events in patients with ASCVD, with an associated reduction in LDL cholesterol levels and risk for new-onset diabetes and intolerance., Study Registration: PROSPERO CRD42024532550.

- Abstract
Background: Intravascular ultrasound (IVUS) guidance has been shown to yield favorable outcomes for endovascular treatment of femoropopliteal artery (FPA) disease with drug-coated balloon (DCB) angioplasty. However, the specific benefits of IVUS for treatment of complex FPA lesions remain uncertain., Objectives: In this study, the authors compared the clinical impact of IVUS-guided vs angiography-guided DCB angioplasty in patients with complex or noncomplex FPA lesions., Methods: This study was a prespecified, primary subgroup analysis of the randomized IVUS-DCB trial. Patients with FPA undergoing DCB angioplasty were randomized to receive the procedure under IVUS or angiography guidance. The primary endpoint was 12-month primary patency; secondary endpoints included clinically driven target lesion revascularization (CD-TLR), sustained clinical improvement, and hemodynamic improvement., Results: Among the 237 patients enrolled, 158 had complex FPA (Trans-Atlantic Inter-Society Consensus II [TASC II] type C/D), and 79 had noncomplex FPA (TASC II type A/B). In complex FPA, IVUS guidance was associated with significantly higher rates of primary patency (82.1% vs 60.3%; HR for loss of primary patency: 0.34; 95% CI: 0.16-0.70; P = 0.002), freedom from CD-TLR (90.0% vs 76.9%; HR: 0.31; 95% CI: 0.13-0.75; P = 0.01), and sustained clinical and hemodynamic improvement relative to angiography guidance. There was no significant difference in primary patency (87.5% vs 88.2%; HR: 1.84; 95% CI: 0.39-8.60; P = 0.44) or occurrence secondary endpoints between the IVUS-guidance and angiography-guidance groups for patients with noncomplex FPA., Conclusions: In endovascular treatment of FPA using DCB, IVUS guidance was significantly associated with improved 12-month clinical outcomes, particularly in patients with complex FPA lesions.(Intravascular Ultrasound-Guided Drug-Coated Balloon Angioplasty for Femoropopliteal Artery Disease [IVUS-DCB] trial; NCT03517904)., Competing Interests: Funding Support and Author Disclosures This study was funded by Medtronic Inc. and Korea United Pharmaceutical, and supported by the Cardiovascular Research Center, Seoul, Korea.

- Abstract
Cancer metastasis is the leading cause of cancer-related deaths, making early detection and the prevention of metastatic progression critical research priorities. Recent studies have expanded our understanding of CEMIP (KIAA1199, HYBID), revealing its involvement in cancer metastasis and its potential role in slowing cancer progression. CEMIP plays critical roles in several stages of cancer metastasis: First, CEMIP promotes cancer cell proliferation to maintain cell heterogeneity before the metastasis process. Second, it facilitates cancer cell detachment by promoting the epithelial-mesenchymal transition (EMT) through alterations in signaling pathways. Third, CEMIP contributes to cancer cell adherence and attachment by enabling cells to withstand cell death (anoikis and ferroptosis) and hypoxia. Fourth, during the invasion process, CEMIP induces hyaluronan depolymerization and further modulates signaling to promote EMT. Lastly, in the pre-metastatic niche, CEMIP influences the tumor microenvironment through hypoxia, angiogenesis, signaling pathway changes, and hyaluronan degradation. Recent studies have focused on leveraging CEMIP as a diagnostic tool or a predictor of metastasis and/or targeting CEMIP to overcome cancer resistance and progression. This review aims to explore the role of CEMIP at each stage of cancer metastasis and highlight recent advances in targeting CEMIP to inhibit cancer progression., (© 2025 The Author(s).

- Abstract
Aims: Using rosuvastatin, the RACING (randomized comparison of efficacy and safety of lipid-lowering with statin monotherapy versus statin/ezetimibe combination for high-risk cardiovascular diseases) trial showed the beneficial effects of combining moderate-intensity statin with ezetimibe compared with high-intensity statin monotherapy in patients with atherosclerotic cardiovascular disease. This study investigated whether the beneficial effects of combination lipid-lowering therapy extend to patients treated with atorvastatin, not rosuvastatin, in daily clinical practice., Methods and Results: Using stabilized inverse probability of treatment weighting, a total of 31 993 patients who were prescribed atorvastatin after drug-eluting stent (DES) implantation were identified from a nationwide cohort database: 6215 patients with atorvastatin 20 mg plus ezetimibe 10 mg (combination lipid-lowering therapy) and 25 778 patients with atorvastatin 40-80 mg monotherapy. The primary endpoint was the 3-year composite of cardiovascular death, myocardial infarction, coronary artery revascularization, hospitalization for heart failure treatment, or non-fatal stroke in accordance with the RACING trial design. Combination lipid-lowering therapy was associated with a lower incidence of the primary endpoint (12.9% vs. 15.1% in high-intensity atorvastatin monotherapy; hazard ratio [HR] 0.81, 95% confidence interval [CI] 0.74-0.88, P < 0.001). Compared with high-intensity atorvastatin monotherapy, combination lipid-lowering therapy was also significantly associated with lower rates of statin discontinuation (10.0% vs. 8.4%, HR 0.81, 95% CI 0.73-0.90, P < 0.001) and new-onset diabetes requiring medication (8.8% vs. 7.0%, HR 0.80, 95% CI 0.70-0.92, P = 0.002)., Conclusion: In clinical practice, a combined lipid-lowering approach utilizing ezetimibe and moderate-intensity atorvastatin was correlated with favourable clinical outcomes, drug compliance, and a reduced incidence of new-onset diabetes requiring medications in patients treated with DES implantation.

- Abstract
Endovascular treatment of femoropopliteal artery (FPA) disease with drug-coated balloons (DCBs) may face complications such as arterial recoil, dissection, and residual stenosis. Angiography has limited accuracy for evaluating blood flow through revascularized target lesions. Thus, there is a need for postprocedure hemodynamic assessment in treated limbs. This study aims to explore how postprocedure ankle-brachial index (ABI) influences outcomes following DCB treatment for FPA disease. This study included patients in a multicenter registry (K-VIS ELLA) treated with DCB for FPA disease between January 2006 and August 2021. Optimal postprocedure ABI cutoff for predicting clinically driven target lesion revascularization (TLR) was determined using receiver operating characteristic curve analysis. Independent predictors of TLR were identified using multivariable Cox regression analysis. A total of 654 limbs (514 patients) treated with DCB for FPA were evaluated by ABI at 1-day (median, interquartile range, 1 to 2 days) postprocedure and followed up for a median of 370 days. The optimal immediate postprocedure ABI cutoff value for predicting TLR was 0.72 (area under the curve, 0.68). Significantly improved TLR-free and major adverse limb event-free survival rates were observed with a postprocedure ABI ≥ 0.72 (hazard ratio [HR] = 0.24, 95% confidence intervals [CI] = 0.16 to 0.37, p < 0.001; HR = 0.25, 95% CI = 0.16 to 0.38, p < 0.001, respectively). Independent predictors of TLR were postprocedure ABI < 0.72 (HR 3.76; 95% CI, 2.33 to 6.07; p < 0.001) and presence of anemia (HR 2.01; 95% CI, 1.03 to 3.92; p = 0.041). An immediate postprocedure ABI is a significant predictor of TLR risk following DCB treatment for FPA disease, underscoring the value of hemodynamic assessment in optimizing angioplasty outcomes., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Young-Guk Ko reports financial support was provided by Patient-Centered Clinical Research Coordinating Center (PACEN) funded by the Ministry of Health & Welfare, Republic of Korea.

- Abstract
Conventional chemotherapy- and radiotherapy-induced cancer senescence, which is characterized by poor proliferation, drug resistance, and senescence-associated secretory phenotype, has gained attention as contributing to cancer relapse and the development of an immunosuppressive tumor microenvironment. However, the association between cancer senescence and anti-tumor immunity is not fully understood. Here, we demonstrate that senescent cancer cells increase the level of PD-L1 by promoting its transcription and glycosylation. We identify ribophorin 1 as a key regulator of PD-L1 glycosylation during cancer senescence. Ribophorin 1 depletion reduces this elevated level of PD-L1 through the ER-lysosome-associated degradation pathway, thereby increasing the susceptibility of senescent cancer cells to T-cell-mediated killing. Consistently, ribophorin 1 depletion suppresses tumor growth by decreasing PD-L1 levels and boosting cytotoxic T lymphocyte activity in male mice. Moreover, ribophorin 1-targeted or anti-PD-1 therapy reduces the number of senescent cancer cells in irradiated tumors and suppresses cancer recurrence through the activation of cytotoxic T lymphocytes. These results provide crucial insights into how senescent cancer cells can escape T-cell immunity following cancer treatment and thereby contribute to cancer recurrence. Our findings also highlight the therapeutic promise of targeting senescent cancer cells for cancer treatment., Competing Interests: Competing interests: The authors declare no competing interests., (© 2025.

- Abstract
Background: Patients with ST-elevation myocardial infarction (STEMI) tend to be excluded or under-represented in randomized clinical trials evaluating the effects of potent P2Y12 inhibitor monotherapy after short-term dual antiplatelet therapy (DAPT)., Methods: Individual patient data were pooled from randomized clinical trials that included STEMI patients undergoing drug-eluting stent (DES) implantation and compared ticagrelor monotherapy after short-term (≤3 months) DAPT versus ticagrelor-based 12-month DAPT in terms of centrally adjudicated clinical outcomes. The co-primary outcomes were efficacy outcome (composite of all-cause death, myocardial infarction, or stroke) and safety outcome (Bleeding Academic Research Consortium type 3 or 5 bleeding) at 1 year., Findings: The pooled cohort contained 2,253 patients with STEMI. The incidence of the primary efficacy outcome did not differ between the ticagrelor monotherapy group and the ticagrelor-based DAPT group (1.8% versus 2.0%; hazard ratio [HR] = 0.88; 95% confidence interval [CI] = 0.49-1.61; p = 0.684). There was no difference in cardiac death between the groups (0.6% versus 0.7%; HR = 0.89; 95% CI = 0.32-2.46; p = 0.822). The incidence of the primary safety outcome was significantly lower in the ticagrelor monotherapy group (2.3% versus 4.0%; HR = 0.56; 95% CI = 0.35-0.92; p = 0.020). No heterogeneity of treatment effects was observed for the primary outcomes across subgroups., Conclusions: In patients with STEMI treated with DES implantation, ticagrelor monotherapy after short-term DAPT was associated with lower major bleeding without an increase in the risk of ischemic events compared with ticagrelor-based 12-month DAPT. Further research is necessary to extend these findings to non-Asian patients., Funding: This study was funded by Biotronik (Bülach, Switzerland)., Competing Interests: Declaration of interests M.-K.H. has received institutional research grants from Sam Jin Pharmaceutical and Chong Kun Dang Pharmaceutical and speaker’s fees from Medtronic and Edward Lifesciences.

- Abstract
A highly effective magnetic nanocomposite alginate beads (PPy-NTs/PEI@Alg@NiFe
2 O4 ) were synthesized using alginate as the encapsulation reagent and polypyrrole/polyethylene imine with nano NiFe2 O4 as a functional filler to remove toxic Zn2+ and Pb2+ from polluted water. A response surface methodology (RSM) was used to statistically assess the influences of pH and the adsorbent dose on the adsorption performance. PPy-NTs/PEI@Alg@NiFe2 O4 magnetic microbeads exhibited the optimal adsorption capacity qe (18.6 mg/g) at pH 6 and a 2 mg/L dose for Zn2+ removal. In comparison, the optimal qe (32.6 mg/g) was reached at pH 4.5 with a 1.5 mg/L dose for Pb2+ remediation. From batch experiments, maximal absorption capacities of 53.3 mg/g and 22 mg/g were achieved for Pb2+ and Zn2+ , respectively, at 313 K. The pseudo-second-order kinetic model fitted the results well, suggesting that the chemisorption process regulates adsorption. Isotherm models indicate the presence of homogeneous adsorption sites from the well-fitting to Langmuir isotherm. An investigation of the effects of temperature and thermodynamic considerations revealed the endothermic nature of Zn2+ and Pb2+ absorption. The Fourier transform infrared spectra showed that -NH, -NH2 , and -COO- are the main groups in PPy-NTs/PEI@Alg@NiFe2 O4 composite beads that were responsible for Zn2+ and Pb2+ removal from polluted water., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
Iliac artery angioplasty with stenting is an effective alternative treatment modality for aortoiliac occlusive diseases. Few randomized controlled trials have compared the efficacy and safety between self-expandable stent (SES) and balloon-expandable stent (BES) in atherosclerotic iliac artery disease. In this randomized, multicenter study, patients with common or external iliac artery occlusive disease were randomly assigned in a 1:1 ratio to either BES or SES. The primary end point was the 1-year clinical patency, defined as freedom from any surgical or percutaneous intervention due to restenosis of the target lesion after the index procedure. The secondary end point was a composite event from major adverse clinical events at 1 year. A total of 201 patients were enrolled from 17 major cardiovascular intervention centers in South Korea. The mean age of the enrolled patients was 66.8 ± 8.5 years and 86.2% of the participants were male. The frequency of critical limb ischemia was 15.4%, and the most common target lesion was in the common iliac artery (75.1%). As the primary end point, the 1-year clinical patency as primary end point was 99% in the BES group and 99% in the SES group (p > 0.99). The rate of repeat revascularization at 1 year was 7.8% in the BES group and 7.0% in the SES group (p = 0.985; confidence interval, 1.011 [0.341-2.995]). In our randomized study, the treatment of iliac artery occlusive disease with self-expandable versus balloon-expandable stent was comparable in 12-month clinical outcomes without differences in the procedural success or geographic miss rate regardless of the deployment method in the distal aortoiliac occlusive lesion (ClinicalTrials.gov, NCT01834495)., Competing Interests: Declarations Conflict of interest The authors declare no competing interests., (© 2024.

- Abstract
Oncogenic Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations are highly prevalent in pancreatic ductal adenocarcinoma (PDAC) and have garnered attention as potential targets for targeted therapies, such as KRAS inhibitors. However, the limited therapeutic efficacy of KRAS allele-specific inhibitors necessitate an efficient pan-KRAS cancer cell killing strategy. Here, we have examined enhanced macropinocytosis pathway in KRAS mutant cancer cells and report improved intracellular delivery of albumin-based therapeutics. We further established an albumin-binding peptide-docetaxel conjugate platform (MPD3), which has a caspase-3 cleavable feature, for macropinocytosis-targeted bystander payload delivery and realization of bystander killing of pan-KRAS cancer cells, complemented with caspase-3 mediated activation of MPD3 to bolster tumoral accumulation of cytotoxic payloads. Utilization of in vitro co-culture system of pan-KRAS cancer cells and pharmacodynamic marker staining revealed potent bystander killing effects of MPD3, highlighting MPD3 as an efficient delivery platform against pan-KRAS cancer. Moreover, MPD3 elicited robust anti-tumor activities in both local and liver metastatic PDAC tumor models in mice. Overall, this work establishes a paradigm for developing translational pan-KRAS cancer treatment and broadens the applicability of albumin binding peptide-drug conjugate against albumin-metabolism enriched cancers., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

- Abstract
This work evaluates the effectiveness of Schiff base derivatives, namely, 2,2'-((1E,1'E)-((2,2-dimethylpropane-1,3-diyl)bis(azaneylylidene))bis(methaneylylidene))diphenol (DAMD) and (2-((E)-((3-(((E)-2-hydroxybenzylidene)amino)-2,2dimethylpropyl)imino)methyl)phenoxy) zinc (HDMZ), as corrosion inhibitors for mild steel in a 15 % HCl solution. By employing a blend of experimental assessments and theoretical computations, such as electrochemical tests, morphological observations, and theoretical simulations, the study achieved an impressive up to 94.6 % inhibition efficiency. Notably, HDMZ exhibited significant protective properties. The results of PDP showed that both inhibitors act as mixed-type corrosion inhibitors. SEM surface analysis of the uninhibited and inhibited samples revealed the formation of a protective layer of inhibitor molecules on the mild steel surface to mitigate its corrosion. The Langmuir adsorption model verified the occurrence of dual adsorption, while theoretical simulations offered insights into the underlying interaction mechanisms. The identification of Schiff-based inhibitors reveals a pronounced synergistic effect in corrosion inhibition, marking a significant advancement in understanding corrosion control mechanisms. This study illuminates the process of forming covalent bonds between inhibitor molecules and iron atoms, presenting a hopeful path towards the advancement of corrosion inhibitors tailored for industrial use. The parallel adsorption configuration and mutual interactions form a stable structure, reinforcing the organic-metal bonds and enhancing both chemical and physical adhesion to the steel surface. These findings indicate that the synergistic effect of molecular interactions and polar-rich regions offers a promising strategy for designing functional hybrid materials., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

- Abstract
Study Objective: Although the importance of primary percutaneous coronary intervention has been emphasized for ST-segment elevation myocardial infarction (STEMI), the appropriateness of the cardiac catheterization laboratory activation remains suboptimal. This study aimed to develop a precise artificial intelligence (AI) model for the diagnosis of STEMI and accurate cardiac catheterization laboratory activation., Methods: We used electrocardiography (ECG) waveform data from a prospective percutaneous coronary intervention registry in Korea in this study. Two independent board-certified cardiologists established a criterion standard (STEMI or Not STEMI) for each ECG based on corresponding coronary angiography data. We developed a deep ensemble model by combining 5 convolutional neural networks. In addition, we performed clinical validation based on a symptom-based ECG data set, comparisons with clinical physicians, and external validation., Results: We used 18,697 ECGs for the model development data set, and 1,745 (9.3%) were STEMI. The AI model achieved an accuracy of 92.1%, sensitivity of 95.4%, and specificity of 91.8 %. The performances of the AI model were well balanced and outstanding in the clinical validation, comparison with clinical physicians, and the external validation., Conclusion: The deep ensemble AI model showed a well-balanced and outstanding performance. As visualized with gradient-weighted class activation mapping, the AI model has a reasonable explainability. Further studies with prospective validation regarding clinical benefit in a real-world setting should be warranted., (Copyright © 2024 American College of Emergency Physicians.

- Abstract
Despite significant progress in combining cancer immunotherapy with chemotherapy to treat triple negative breast cancer (TNBC), challenges persist due to target depletion and tumor heterogeneity, especially in metastasis. Chemotherapy lacks precise targeting abilities, and targeted therapy is inadequate in addressing the diverse heterogeneity of tumors. To address these challenges, we introduce RGDEVD-DOX as a tumor-specific immunogenic agent, namely TPD1, which targets integrin αvβ3 and gets continuously activated by apoptosis. TPD1 facilitates the caspase-3-mediated in situ amplification that results in tumor-specific accumulation of doxorubicin. This local concentration of doxorubicin induces immunogenic cell death and promotes the recruitment of immune cells to the tumor site. Notably, the tumor-targeting capabilities of TPD1 help bypass the systemic immunotoxicity of doxorubicin. Consequently, this alters the tumor microenvironment, converting it into a 'hot' tumor that is more susceptible to immune checkpoint inhibition. We demonstrated the anti-metastatic and anti-cancer efficacy of this treatment using various xenograft and metastatic models. This study underscores the high potential of caspase-3 cleavable peptide-drug conjugates to be used in conjunction with anti-cancer immunotherapies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
Background: After coronary stent implantation, prolonged dual antiplatelet therapy (DAPT) increases bleeding risk, requiring personalization of DAPT duration. The aim of this study was to develop and validate a machine learning model to predict optimal DAPT duration after contemporary drug-eluting stent implantation in patients with coronary artery disease., Methods and Results: The One-Month DAPT, RESET (Real Safety and Efficacy of 3-Month Dual Antiplatelet Therapy Following Endeavor Zotarolimus-Eluting Stent Implantation), and IVUS-XPL (Impact of Intravascular Ultrasound Guidance on Outcomes of Xience Prime Stents in Long Lesion) trials provided a derivation cohort (n=6568). Using the X-learner approach, an individualized DAPT score was developed to determine the therapeutic benefit of abbreviated (1-6 months) versus standard (12-month) DAPT using various predictors. The primary outcome was major bleeding; the secondary outcomes included 1-year major adverse cardiac and cerebrovascular events and 1-year net adverse clinical events. The risk reduction with abbreviated DAPT (3 months) in the individualized DAPT-determined higher predicted benefit group was validated in the TICO (Ticagrelor Monotherapy After 3 Months in the Patients Treated With New Generation Sirolimus-Eluting Stent for Acute Coronary Syndrome) trial (n=3056), which enrolled patients with acute coronary syndrome treated with ticagrelor. The validation cohort comprised 1527 abbreviated and 1529 standard DAPT cases. Major bleeding occurred in 25 (1.7%) and 45 (3.0%) patients in the abbreviated and standard DAPT groups, respectively. The individualized DAPT score identified 2582 (84.5%) participants who would benefit from abbreviated DAPT, which was significantly associated with a lower major bleeding risk (absolute risk difference [ARD], 1.26 [95% CI, 0.15-2.36]) and net adverse clinical events (ARD, 1.59 [95% CI, 0.07-3.10]) but not major adverse cardiac and cerebrovascular events (ARD, 0.63 [95% CI, -0.34 to 1.61]), compared with standard DAPT in the higher predicted benefit group. Abbreviated DAPT had no significant difference in clinical outcomes of major bleeding (ARD, 1.49 [95% CI, -1.74 to 4.72]), net adverse clinical events (ARD, 2.57 [95% CI, -1.85 to 6.99]), or major adverse cardiac and cerebrovascular events (ARD, 1.54 [95% CI, -1.26 to 4.34]), compared with standard DAPT in the individualized DAPT-determined lower predicted benefit group., Conclusions: Machine learning using the X-learner approach identifies patients with acute coronary syndrome who may benefit from abbreviated DAPT after drug-eluting stent implantation, laying the groundwork for personalized antiplatelet therapy.

- Abstract
Background: Endovascular therapy (EVT) has become the preferred treatment modality for femoropopliteal disease. However, there is limited evidence regarding its procedural and clinical outcomes according to the affected area., Aims: The aim of this study is to investigate clinical outcomes and device effectiveness according to treatment extent in the superficial femoral artery (SFA), popliteal artery (PA), or both., Methods: In this study, we analysed EVT for SFA (2,404 limbs), PA (155 limbs), SFA/PA (383 limbs) using the population in the K-VIS ELLA (Korean Vascular Intervention Society Endovascular Therapy in Lower Limb Artery Diseases) registry. The primary endpoint was target lesion revascularisation (TLR) at 2 years., Results: The SFA/PA group exhibited a higher prevalence of anatomical complexity, characterised by long lesions, moderate to severe calcification, and total occlusion. The procedures were successful in 97.2% of SFA, 92.9% of PA, and 95.6% of SFA/PA EVTs. The 2-year TLR rates were 21.1%, 18.6%, and 32.7% in the SFA, PA, and SFA/PA groups, respectively. SFA/PA EVT was associated with a significantly increased risk for TLR compared to the SFA group (adjusted hazard ratio [HR] 1.48 [1.09-2.00]; p=0.008) and a trend towards an increased risk compared to the PA group (adjusted HR 1.80 [1.00-3.27]; p=0.052). After overlap weighting, the use of a drug-coated balloon (DCB) was shown to be beneficial, with the lowest TLR rate after SFA and SFA/PA EVT., Conclusions: In this large real-world registry, SFA/PA EVT was associated with an increased risk for TLR at 2 years compared to the SFA or PA EVT groups, with favourable outcomes when using a DCB or drug-eluting stent in the SFA/PA EVT group.

- Abstract
Background: Despite the detailed imaging information provided by optical coherence tomography (OCT) during percutaneous coronary intervention (PCI), clinical benefits of this imaging technique in this setting remain uncertain. The aim of the OCCUPI trial was to compare the clinical benefits of OCT-guided versus angiography-guided PCI for complex lesions, assessed as the rate of major adverse cardiac events at 1 year., Methods: This investigator-initiated, multicentre, randomised, open-label, superiority trial conducted at 20 hospitals in South Korea enrolled patients aged 19-85 years for whom PCI with drug-eluting stents was clinically indicated. After diagnostic angiography, clinical and angiographic findings were assessed to identify patients who met the criterion of having one or more complex lesions. Patients were randomly assigned 1:1 to receive PCI with OCT guidance (OCT-guidance group) or angiography guidance without OCT (angiography-guidance group). Web-response permuted-block randomisation (mixed blocks of four or six) was used at each participating site to allocate patients. The allocation sequence was computer-generated by an external programmer who was not involved in the rest of the trial. Outcome assessors were masked to group assignment. Patients, follow-up health-care providers, and data analysers were not masked. PCI was done according to conventional standard methods with everolimus-eluting stents. The primary endpoint was major adverse cardiac events (a composite of cardiac death, myocardial infarction, stent thrombosis, or ischaemia-driven target-vessel revascularisation), 1 year after PCI. The primary analysis was done in the intention-to-treat population. The margin used to establish superiority was 1·0 as a hazard ratio. This trial is registered with ClinicalTrials.gov (NCT03625908) and is completed., Findings: Between Jan 9, 2019, and Sept 22, 2022, 1604 patients requiring PCI with drug-eluting stents for complex lesions were randomly assigned to receive either OCT-guided PCI (n=803) or angiography-guided PCI (n=801). 1290 (80%) of 1604 patients were male and 314 (20%) were female. The median age of patients at randomisation was 64 years (IQR 57-70). 1588 (99%) patients completed 1-year follow-up. The primary endpoint occurred in 37 (5%) of 803 patients in the OCT-guided PCI group and 59 (7%) of 801 patients in the angiography-guided PCI group (absolute difference -2·8% [95% CI -5·1 to -0·4]; hazard ratio 0·62 [95% CI 0·41 to 0·93]; p=0·023). Rates of stroke, bleeding events, and contrast-induced nephropathy were not significantly different across the two groups., Interpretation: Among patients who required drug-eluting stent implantation for complex lesions, OCT guidance resulted in a lower incidence of major adverse cardiac events at 1 year compared with angiography guidance. These findings indicate the existence of a therapeutic benefit of OCT as an intravascular imaging technique for PCI guidance in patients with complex coronary lesions., Funding: Abbott Vascular and Cardiovascular Research Center., Translation: For the Korean translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests S-JH reports speaker fees from AstraZeneca, Amgen, ChongKunDang, Hanmi, and Viatris; and participation on the data safety monitoring board of the IVUS-DCB trial.

- Abstract
Because there is a lack of comparative studies assessing drug-coated balloon (DCB) and drug-eluting stent (DES) outcomes with respect to intraluminal (IL) and subintimal (SI) approaches in femoropopliteal (FP) total occlusive lesions, we compared the outcomes between DCB (including bailout stenting) and DES treatments for this lesion. A total of 487 limbs (434 patients) were divided into the IL (n = 344, DCB: n = 268, DES: n = 76) and SI (n = 143, DCB: n = 83, DES: n = 60) approach groups. The primary outcome was a major adverse limb event (MALE), defined as above-ankle amputation or repeat revascularization of the index limb. Secondary outcomes included clinically driven target lesion revascularization (TLR), loss of clinical patency, and all-cause death. After adjustment, in each IL and SI approach, the 2-year rates of MALE (p = 0.180 and p = 0.236, respectively), TLR, loss of clinical patency, and all-cause death were similar between the DCB and DES groups. In the DCB and DES groups, both primary and secondary outcomes were similar between the IL and SI approaches. DCB and DES strategies for patients presenting with FP total occlusive lesions demonstrated similar outcomes regardless of the IL or SI approach.Clinical Trial Registration: NCT02748226., (© 2024.

- Abstract
Superovulation is a technique used to increase the number of oocytes released for fertilization. This study investigated the effects of short-term differences in concentrate feed intake on in vivo embryo production through superovulation in indigenous Korean (Hanwoo) cows. The cows were given fresh water and hay ad libitum and randomly divided into three groups (control (CON, n = 9): 2.0 kg/day (unchanged diet); low concentrate (LC, n = 10): 0 kg/day; and high concentrate (HC, n = 8): 4.0 kg/day) according to the amount of formula they were fed. This feeding treatment began seven days before the start of the hormonal treatment for superovulation. From the results, the LC group had the greatest weight change and the lowest body condition score at harvest, followed by the CON and HC groups ( p < 0.05). The LC group had the highest number of harvesting embryos, followed by the HC and CON groups ( p < 0.05). Estradiol, progesterone, glucose, total cholesterol, high-density lipoprotein, low-density lipoprotein, total protein, and blood urea nitrogen concentrations did not differ between the groups, except for a temporary increase in the HC group on day 0. These findings suggest that more embryos may be harvested when short-term changes in concentrate intake are made during superovulatory responses in Hanwoo cows.

- Abstract
Background and Objectives: The K-ELUVIA study aimed to investigate the clinical effectiveness and safety of Eluvia™, a polymer-coated, paclitaxel-eluting stent, for femoropopliteal artery disease using data from a prospective Korean multicenter registry., Methods: A total of 105 patients with femoropopliteal artery disease who received endovascular treatment (EVT) with Eluvia™ stents at 7 Korean sites were enrolled in a prospective cohort and followed for 2 years. The primary endpoint was the 2-year clinical patency. The secondary endpoint was 2-year freedom from clinically driven target lesion revascularization (TLR)., Results: Mean patient age was 68.2±10.4 years, and most patients (82.7%) were male. Mean lesion length was 168.3±117.6 mm. Chronic total occlusion was found in 57.7% of patients. Trans-Atlantic Inter-Society Consensus for the Management of Peripheral Arterial Disease (TASC II) type C or D lesions were present in 46.1% of patients. Procedural success was achieved in 99.0% of patients. The clinical patency rate was 84.4% at 1 year after EVT and 76.3% at 2 years post-EVT. The freedom from TLR rate was 89.1% at 1 year after EVT and 79.1% at 2 years post-EVT. Chronic total occlusion (hazard ratio [HR], 3.53; 95% confidence interval [CI], 1.08-11.67; p=0.039) and smaller mean stent diameter (HR, 0.40; 95% CI, 0.16-0.98; p=0.044) were identified as independent predictors of loss of clinical patency at 2 years., Conclusions: The K-ELUVIA study demonstrated favorable 2-year clinical effectiveness and safety outcomes of Eluvia stent for femoropopliteal artery lesions in real-world practice., Competing Interests: The authors have no financial conflicts of interest., (Copyright © 2024.

- Abstract
Background and Aims: In patients with acute coronary syndrome (ACS), dual antiplatelet therapy (DAPT) with aspirin and a potent P2Y12 inhibitor is recommended for 12 months after drug-eluting stent (DES) implantation. Monotherapy with a potent P2Y12 inhibitor after short-term DAPT is an attractive option to better balance the risks of ischaemia and bleeding. Therefore, this study evaluated the efficacy and safety of ticagrelor monotherapy after short-term DAPT, especially in patients with ACS., Methods: Electronic databases were searched from inception to 11 November 2023, and for the primary analysis, individual patient data were pooled from the relevant randomized clinical trials comparing ticagrelor monotherapy after short-term (≤3 months) DAPT with ticagrelor-based 12-month DAPT, exclusively in ACS patients undergoing DES implantation. The co-primary endpoints were ischaemic endpoint (composite of all-cause death, myocardial infarction, or stroke) and bleeding endpoint [Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding] at 1 year., Results: Individual patient data from two randomized clinical trials including 5906 ACS patients were analysed. At 1 year, the primary ischaemic endpoint did not differ between the ticagrelor monotherapy and ticagrelor-based DAPT groups [1.9% vs. 2.5%; adjusted hazard ratio (HR) 0.79; 95% confidence interval (CI) 0.56-1.13; P = .194]. The incidence of the primary bleeding endpoint was lower in the ticagrelor monotherapy group (2.4% vs. 4.5%; adjusted HR 0.54; 95% CI 0.40-0.72; P < .001). The results were consistent in a secondary aggregate data meta-analysis including the ACS subgroup of additional randomized clinical trials which enrolled patients with ACS as well as chronic coronary syndrome., Conclusions: In ACS patients undergoing DES implantation, ticagrelor monotherapy after short-term DAPT was associated with less major bleeding without a concomitant increase in ischaemic events compared with ticagrelor-based 12-month DAPT., Study Registration: PROSPERO (ID: CRD42023476470)., (© The Author(s) 2024.

- Abstract
A lot of research has been focused on increasing the specific surface area of adsorbents over a long period of time to remove heavy metal ions from wastewater using the adsorbent. However, porous adsorbents with high specific surface area have demonstrated drawbacks in water purification processes, such as high pressure drop and limitations in the adsorption capacity of heavy metal ions. In recent years, a mechanism-based convergence method involving adsorption/chemical precipitation has emerged as a promising strategy to surmount the constraints associated with porous adsorbents. The mechanism involves amine groups on chelating fibers dissociating OH
- ions from water molecules, thereby raising the pH near the fibers. This elevated pH promotes the crystallization of heavy metal ions on the fiber surfaces. The removal of heavy metal ions proceeds through a sequence of adsorption and chemical precipitation processes. An adsorbent based on chelating fibers, integrating adsorption technology with chemical precipitation, demonstrates superior performance in removing significant quantities of heavy metal ions (ca. 1000-2000 mg/g for Cd2+ , Cu2+ and Pb2+ ) when compared to developed porous adsorbents (ca. 50-760 mg/g for same ions). This review paper introduces advanced polymer fibers endowed with the capability to integrate hybrid technology, delves into the mechanism of hybrid technology, and examines its application in process technology for the effective removal of heavy metal ions. The versatility of these advanced fibers extends far beyond the removal of heavy metal ions in water treatment, making them poised to garner significant attention from researchers across diverse fields due to their broad range of potential applications. After further processes involving the removal of templates from chelating polymeric fibers used as supports and the reduction of precipitated heavy metal oxide crystals, the resulting heavy metal crystals can exhibit thin walls and well-interconnected porous structures, suitable for catalytic applications., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Background and Aims: Drug-coated balloons (DCBs) have demonstrated favourable outcomes following endovascular therapy for femoropopliteal artery (FPA) disease. However, uncertainty remains whether the use of intravascular ultrasound (IVUS) can improve the outcomes of DCBs., Methods: This prospective, multicentre, randomized trial, conducted at seven centres in South Korea, compared the outcomes of IVUS-guided vs. angiography-guided angioplasty for treating FPA disease with DCBs. Patients were assigned to receive IVUS-guided (n = 119) or angiography-guided (n = 118) angioplasty using DCBs. The primary endpoint was 12-month primary patency., Results: Between May 2016 and August 2022, 237 patients were enrolled and 204 (86.0%) completed the trial (median follow-up; 363 days). The IVUS guidance group showed significantly higher primary patency [83.8% vs. 70.1%; cumulative difference 19.6% (95% confidence interval 6.8 to 32.3); P = .01] and increased freedom from clinically driven target lesion revascularization [92.4% vs. 83.0%; difference 11.6% (95% confidence interval 3.1 to 20.1); P = .02], sustained clinical improvement (89.1% vs. 76.3%, P = .01), and haemodynamic improvement (82.4% vs. 66.9%, P = .01) at 12 months compared with the angiography guidance group. The IVUS group utilized larger balloon diameters and pressures for pre-dilation, more frequent post-dilation, and higher pressures for post-dilation, resulting in a greater post-procedural minimum lumen diameter (3.90 ± 0.59 vs. 3.71 ± 0.73 mm, P = .03)., Conclusions: Intravascular ultrasound guidance significantly improved the outcomes of DCBs for FPA disease in terms of primary patency, freedom from clinically driven target lesion revascularization, and sustained clinical and haemodynamic improvement at 12 months. These benefits may be attributed to IVUS-guided optimization of the lesion before and after DCB treatment., (© The Author(s) 2024.

- Abstract
Background: The impact of rosuvastatin versus atorvastatin on new-onset diabetes mellitus (NODM) among patients treated with high-intensity statin therapy for coronary artery disease (CAD) remains to be clarified. This study aimed to evaluate the risk of NODM in patients with CAD treated with rosuvastatin compared to atorvastatin in the randomized LODESTAR trial., Methods: In the LODESTAR trial, patients with CAD were randomly assigned to receive either rosuvastatin or atorvastatin using a 2-by-2 factorial randomization. In this post-hoc analysis, the 3-year incidence of NODM was compared between rosuvastatin and atorvastatin treatment in the as-treated population with high-intensity statin therapy as the principal population of interest., Results: Among 2932 patients without diabetes mellitus at baseline, 2377 were included in the as-treated population analysis. In the as-treated population with high-intensity statin therapy, the incidence of NODM was not significantly different between the rosuvastatin and atorvastatin groups (11.4% [106/948] versus 8.8% [73/856], hazard ratio [HR] = 1.32, 95% confidence interval [CI] = 0.98 to 1.77, P = 0.071). When the risk of NODM with rosuvastatin versus atorvastatin was assessed according to the achieved low-density lipoprotein cholesterol (LDL-C) level, the risk of NODM began to increase at a LDL-C level below 70 mg/dL. The incidence of NODM was significantly greater in the rosuvastatin group than it was in the atorvastatin group when the achieved LDL-C level was < 70 mg/dL (13.9% versus 8.0%; HR = 1.79, 95% CI 1.18 to 2.73, P = 0.007)., Conclusions: Among CAD patients receiving high-intensity statin therapy, the incidence of NODM was not significantly different between rosuvastatin and atorvastatin. However, a drug effect of the statin type on NODM was observed when the achieved LDL-C level was < 70 mg/dL., Trial Registration: ClinicalTrials.gov, Identifier: NCT02579499., (© 2024.

- Abstract
Background: The indications, benefits, and outcomes of percutaneous transluminal renal artery intervention (PTRI) remain controversial. The study purpose was to evaluate the long-term outcomes of PTRI in clinical practice., Methods: A retrospective review of 217 subjects (254 renal arteries; mean age, 59.8 years) who underwent PTRI based on medical database., Results: The most common cause of renal artery stenosis was atherosclerosis in 217 (85.4%), followed by Takayasu arteritis (TA) in 23 (9.1%), fibromuscular dysplasia in five (2.0%) and others in nine (3.5%). Mean follow-up duration was 5.7 ± 3.7 years. The first restenosis rate was 7.5% (n = 19; highest in TA: n = 9, 47.4%) and second restenosis occurred in six arteries (five TAs, one fibromuscular dysplasia). Follow-up blood pressure improved from 142.0/83.5 to 122.8/73.5 mmHg (P < 0.001). There was no change within 5 years' follow-up in estimated glomerular filtration rate (P = 0.44), whereas TA changed from 69.8 ± 20.5 to 84.2 ± 17.9 mL/min/1.73 m² (P = 0.008). Progressive renal dysfunction was related to diabetes mellitus, chronic kidney disease, and peripheral artery obstructive disease on multivariate analysis with hazard ratios (95% confidence intervals) of 2.24 (1.21-4.17), 2.54 (1.33-4.84), and 3.93 (1.97-7.82), respectively., Conclusions: PTRI was associated with a blood pressure reduction. Despite a higher rate of restenosis, patients with TA showed significant improvement in estimated glomerular filtration rate. Diabetes mellitus, chronic kidney disease, and peripheral artery obstructive disease were related with progressive renal dysfunction after PTRI., (© 2024. The Author(s).)

- Abstract
Background and Objectives: The popliteal artery is generally regarded as a "no-stent zone." Limited data are available on the outcomes of drug-coated balloons (DCBs) for popliteal artery disease. This study aimed to evaluate the 12-month clinical outcomes among patients who received DCB treatment for atherosclerotic popliteal artery disease., Methods: This prospective, multicenter registry study enrolled 100 patients from 7 Korean endovascular centers who underwent endovascular therapy using IN.PACT DCB (Medtronic) for symptomatic atherosclerotic popliteal artery disease. The primary endpoint was 12-month clinical primary patency and the secondary endpoint was clinically driven target lesion revascularization (TLR)-free rate., Results: The mean age of the study cohort was 65.7±10.8 years, and 77% of enrolled patients were men. The mean lesion length was 93.7±53.7 mm, and total occlusions were present in 45% of patients. Technical success was achieved in all patients. Combined atherectomy was performed in 17% and provisional stenting was required in 11%. Out of the enrolled patients, 91 patients completed the 12-month follow-up. Clinical primary patency and TLR-free survival rates at 12 months were 76.0% and 87.2%, respectively. A multivariate Cox regression analysis identified female and longer lesion length as the significant independent predictors of loss of patency., Conclusions: DCB treatment yielded favorable 12-month clinical primary patency and TLR-free survival outcomes in patients with popliteal artery disease., Trial Registration: ClinicalTrials.gov Identifier: NCT02698345., Competing Interests: Dr. Ko and Dr. Choi received research grants from Medtronic, Boston Scientific, Samjin Pharm, Korea United Pharm, Dong-A Pharm, and Otsuka, Korea.

- Abstract
KRAS-mutant cancers, due to their protein targeting complexity, present significant therapeutic hurdles. The identification of the macropinocytic phenotype in these cancers has emerged as a promising alternative therapeutic target. Our study introduces MPD1, an macropinocytosis-targeting peptide-drug conjugates (PDC), which is developed to treat KRAS mutant cancers. This PDC is specifically designed to trigger a positive feedback loop through its caspase-3 cleavable characteristic. However, we observe that this loop is hindered by DNA-PK mediated DNA damage repair processes in cancer cells. To counter this impediment, we employ AZD7648, a DNA-PK inhibitor. Interestingly, the combined treatment of MPD1 and AZD7648 resulted in a 100% complete response rate in KRAS-mutant xenograft model. We focus on the synergic mechanism of it. We discover that AZD7648 specifically enhances macropinocytosis in KRAS-mutant cancer cells. Further analysis uncovers a significant correlation between the increase in macropinocytosis and PI3K signaling, driven by AMPK pathways. Also, AZD7648 reinforces the positive feedback loop, leading to escalated apoptosis and enhanced payload accumulation within tumors. AZD7648 possesses broad applications in augmenting nano-sized drug delivery and preventing DNA repair resistance. The promising efficacy and evident synergy underscore the potential of combining MPD1 with AZD7648 as a strategy for treating KRAS-mutant cancers., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

- Abstract
Background: Remnant cholesterol (remnant-C) levels during lipid-lowering therapy (LLT) may indicate residual risk., Objective: We aimed to investigate the clinical outcomes based on on-treatment remnant-C distribution in patients with atherosclerotic cardiovascular disease (ASCVD) under statin-based LLT., Methods: In this post hoc analysis of the RACING trial, 3,348 ASCVD patients with lipid profiles 1 year after randomization were investigated. Remnant-C was calculated as total cholesterol minus low-density lipoprotein cholesterol (LDL-C) minus high-density lipoprotein cholesterol. The primary endpoint was a 3-year composite of cardiovascular death, major cardiovascular events, or non-fatal stroke., Results: The study population was grouped into tertiles according to on-treatment remnant-C: high (> 20.5 mg/dL; n = 1,116), intermediate (14‒20.5 mg/dL; n = 1,031), and low (≤14.0 mg/dL; n = 1,201) remnant-C groups. The high remnant-C group showed the highest incidence of the primary endpoint at 3 years (11.0 %, 10.3 %, and 7.5 % in the high, intermediate, and low remnant-C groups, respectively; p = 0.009). The high remnant-C levels at 1 year were independently associated with an increased risk of the primary outcome, whereas achieving LDL-C <55 or 70 mg/dL was not associated with the incidence of the primary endpoint. The on-treatment remnant-C cut-off of 17 mg/dL (median) demonstrated the ability to discriminate between patients at higher and lower risks for the primary endpoints (hazard ratio: 1.42; 95 % confidence interval: 1.14‒1.78; p = 0.002)., Conclusions: In patients with ASCVD undergoing statin-based LLT, high on-treatment remnant-C values were associated with unfavorable clinical outcomes. On-treatment remnant-C levels may serve as an additional means of assessing residual cardiovascular risk., Clinical Trial Registration: ClinicalTrials. gov ID: NCT03044665., Competing Interests: Conflict of interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

- Abstract
Introduction: Previous research has highlighted the duality of self-consciousness, which simultaneously plays adaptive and maladaptive roles. This study aims to develop a measure that categorically distinguishes between different types of self-consciousness styles based on the Regulatory Focus Theory (RFT) and examines their relationship with mental health-related indicators., Methods: Data were gathered through an online mental health survey conducted at a University Student Counseling Center in Seoul. The study involved exploratory factor analysis, confirmatory factor analysis, and reliability and validity analysis, which resulted in the development of a 14-question Self-Consciousness Type Scale (SCTS)., Results: Both exploratory and confirmatory factor analyses validated the two-factor structure of the SCTS. The fit indices of the final model indicated a good fit, with high internal consistency for both sub-factors. Convergent and discriminant validity were confirmed through correlations between the sub-scales. Cluster analysis identified four distinct subtypes of self-consciousness styles: Growth-oriented, Defensive, Ambivalent, and Low-focus self-consciousness. Group difference analysis revealed significant differences in mental health-related variables among the subtypes, supporting the 2 × 2 model of prevention-focused and promotion-focused self-consciousness., Discussion: The findings support the SCTS as a valid measurement tool capable of distinguishing four distinct types of self-consciousness, aligning with the multidimensional model of self-consciousness. The study's limitations and implications were discussed based on the results, emphasizing the potential applications of the SCTS in mental health research and practice., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Lee, Baek, Oh, Kim and Ko.)

- Abstract
Background: The optimal statin treatment strategy that is balanced for both efficacy and safety has not been clearly determined in older adults with coronary artery disease (CAD)., Methods: In the post hoc analysis of the LODESTAR (low-density lipoprotein cholesterol-targeting statin therapy versus intensity-based statin therapy in patients with coronary artery disease) trial, the impact between a treat-to-target strategy versus a high-intensity statin therapy strategy was compared in older adults (aged 75 years or older). The goal of treat-to-target low-density lipoprotein cholesterol (LDL-C) level was 50-70 mg/dl. The primary endpoint comprised the three-year composite of all-cause death, myocardial infarction, stroke or coronary revascularisation., Results: Among 4,400 patients with CAD enrolled in the LODESTAR trial, 822 (18.7%) were aged 75 years or older. Poor clinical outcomes and risk factors for atherosclerosis were more frequently observed in older adults than in younger population (<75 years old). Among these older adults with CAD, the prescription rate of high-intensity statin was significantly lower in the treat-to-target strategy group throughout the study period (P < 0.001). The mean LDL-C level for three years was 65 ± 16 mg/dl in the treat-to-target strategy group and 64 ± 18 mg/dl in the high-intensity statin group (P = 0.34). The incidence of primary endpoint occurrence was 10.9% in the treat-to-target strategy group and 12.0% in the high-intensity statin group (hazard ratio 0.92, 95% confidence interval 0.61-1.38, P = 0.69)., Conclusions: High-intensity statin therapy is theoretically more necessary in older adults because of worse clinical outcomes and greater number of risk factors for atherosclerosis. However, the primary endpoint occurrence with a treat-to-target strategy with an LDL-C goal of 50-70 mg/dl was comparable to that of high-intensity statin therapy and reduced utilisation of a high-intensity statin. Taking efficacy as well as safety into account, adopting a tailored approach may be considered for this high-risk population., Trial Registration: ClinicalTrials.gov, NCT02579499., (© The Author(s) 2024.

- Abstract
Background: Functional assessment using fractional flow reserve (FFR) and anatomical assessment using optical coherence tomography (OCT) are used in clinical practice for patients with intermediate coronary stenosis. Moreover, coronary computed tomography angiography (CTA) is a common noninvasive imaging technique for evaluating suspected coronary artery disease before being referred for angiography. This study aimed to investigate the association between FFR and plaque characteristics assessed using coronary CTA and OCT for intermediate coronary stenosis., Methods: Based on a prospective multicenter registry, 159 patients having 339 coronary lesions with intermediate stenosis were included. All patients underwent coronary CTA before being referred for coronary angiography, and both FFR measurements and OCT examinations were performed during angiography. A stenotic lesion identified with FFR ≤0.80 was deemed diagnostic of an ischemia-causing lesion. The predictive value of plaque characteristics assessed using coronary CTA and OCT for identifying lesions causing ischemia was analyzed., Results: Stenosis severity and plaque characteristics on coronary CTA and OCT differed between lesions that caused ischemia and those that did not. In multivariate analysis, low attenuation plaque on coronary CTA (odds ratio [OR]=2.78; P=0.038), thrombus (OR=5.13; P=0.042), plaque rupture (OR=3.25; P=0.017), and intimal vasculature on OCT (OR=2.57; P=0.012) were independent predictors of ischemic lesions. Increasing the number of these plaque characteristics offered incremental improvement in predicting the lesions causing ischemia., Conclusions: Comprehensive anatomical evaluation of coronary stenosis may provide additional supportive information for predicting the lesions causing ischemia., Competing Interests: Declaration of competing interest J.-S.K. has received proctoring fees from Abbott Vascular.
