Arteriovenous (AV) shunts are relatively uncommon in the liver and usually associated with advanced hepatocellular carcinoma (HCC). In patients with massive AV shunts complicating advanced HCC, transarterial chemoinfusion therapy is not effective because chemotherapeutic agents go through the shunts and may cause systemic toxicity as well as decrease the chemotherapeutic effects against the tumor. We report two cases of successful transcatheter venous embolization of massive AV shunts complicating advanced HCC using the Amplatzer Vascular Plug for transarterial chemoinfusion therapy.

Purpose: To compare oncologic outcomes of transarterial chemoembolization (TACE) using 70-150-μm and 100-300-μm drug-eluting embolics (DEEs) to treat small hepatocellular carcinoma (HCC)., Materials and Methods: This retrospective study included 93 patients with small HCC (≤3 cm) who underwent their first TACE with DEEs: (a) 43 with 70-150-μm DEEs and (b) 50 with 100-300-μm DEEs. Initial tumor response was assessed using per-patient and per-lesion analyses. Progression-free survival (PFS) and target tumor PFS were analyzed for patients and lesions with initial complete response (CR). Overall survival (OS) and safety outcomes were also evaluated., Results: At 1 month, initial CR rates were 72.1% in the 70-150-μm group and 70.0% in the 100-300-μm group. PFS was significantly longer in the 70-150-μm group (median, 26 months) compared with that in the 100-300-μm group (median, 11 months; log-rank P = .049), with comparable OS results (P = .096, median not reached at 36 months for either group). Per-lesion analysis found that target tumor PFS was significantly longer in the 70-150-μm group (median, 30 months) compared with that in the 100-300-μm group (median, 13 months; P = .009). Subgroup analysis revealed that the 70-150-μm group had significantly longer target tumor PFS compared with the 100-300-μm group in the 1.0-2.0-cm subgroup (P = .017), but not in the 2.1-3.0-cm subgroup (P = .117). No significant differences in adverse events were observed between the 2 groups., Conclusions: The 70-150-μm and 100-300-μm DEE-TACEs resulted in comparable tumor response and short-term safety in small HCCs (≤3 cm). However, in cases where CR was achieved, treatment with smaller microspheres demonstrated longer PFS and target tumor PFS., (Copyright © 2024. Published by Elsevier Inc.)

Background: Current guidelines recommend intervention for asymptomatic rheumatic mitral stenosis (MS) with mitral valve area ≤1.5 cm 2 based on indicators including pulmonary arterial systolic pressure (PASP) >50 mm Hg and new-onset atrial fibrillation; however, evidence supporting this is lacking., Methods: This single-center retrospective study included patients with rheumatic MS between 2006 and 2022. Pulmonary hypertension was evaluated by using echocardiography to estimate PASP. Primary outcomes were major adverse cardiovascular events (MACE), including all-cause mortality, hospitalization for heart failure, and arterial thromboembolic events for up to 5 years., Results: Overall, 287 patients with severe rheumatic MS were enrolled (mean age, 62.5±11.3 years; 74.6% women). During a median follow-up of 2.52 years, MACE occurred in 99 patients. There were no differences in echocardiographic parameters, such as the mean mitral valve pressure gradient, mitral valve area, and proportion of mitral valve area <1.0 cm 2 , between patients who developed primary outcomes and those who did not. Survival analysis showed a worse prognosis in patients with estimated PASP (ePASP) >50 mm Hg than in those with ePASP ≤50 mm Hg (log-rank P <0.001); however, atrial fibrillation was not a significant prognostic indicator. As a continuous variable, ePASP (mm Hg) was a significant predictor of MACE (adjusted hazard ratio, 1.027 [95% CI, 1.011-1.042]; P <0.001). Receiver operating characteristic analysis revealed an optimal ePASP threshold of >45 mm Hg, which was an independent predictor of MACE in patients with severe rheumatic MS (adjusted hazard ratio, 2.127 [95% CI, 1.424-3.177]; P <0.001). Competing risk analysis considering mitral valve intervention as a competing risk showed similar results., Conclusions: Our study demonstrated the prognostic significance of ePASP, rather than atrial fibrillation, in relation to MACE among patients with severe rheumatic MS. Additionally, we proposed a lower ePASP threshold (>45 mm Hg) as a predictor of an unfavorable prognosis., Competing Interests: None.

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the suggestion that Ryugu/CI chondrites formed in a different region of the accretion disk, possibly around the orbits of Uranus and Neptune. We show that, like for Fe, Ryugu and CI chondrites also have indistinguishable Ni isotope anomalies, which differ from those of other carbonaceous chondrites. We propose that this unique Fe and Ni isotopic composition reflects different accretion efficiencies of small FeNi metal grains among the carbonaceous chondrite parent bodies. The CI chondrites incorporated these grains more efficiently, possibly because they formed at the end of the disk's lifetime, when planetesimal formation was also triggered by photoevaporation of the disk. Isotopic variations among carbonaceous chondrites may thus reflect fractionation of distinct dust components from a common reservoir, implying CI chondrites/Ryugu may have formed in the same region of the accretion disk as other carbonaceous chondrites.

Objective: This study aimed to compare transarterial chemoembolization (TACE) and transarterial radioembolization (TARE) as first-line treatments for unresectable HCC > 8 cm., Methods: This retrospective study analyzed 129 HCC patients with tumor diameters greater than 8 cm from January 2010 to December 2021, including 40 patients who received TARE, and 89 patients treated with TACE as primary treatment. Following Propensity Score Matching (PSM), 40 patients from each group were harmonized for baseline characteristics. Tumor responses were evaluated using mRECIST criteria, and survival outcomes were compared between treatment groups using Kaplan-Meier curves and the Log-rank test., Results: There was no significant difference in the objective response rate (ORR) and disease control rate (DCR) at 3, 6, and 12 months between the two groups; ORR and DCR were 72.6%, 83.1% in TACE group vs. 72.5%. 87.5% in TARE group for best tumor response (p-values: 0.625 and 0.981, respectively). Overall survival (OS) and progression-free survival (PFS) between the two groups were comparable pre- and post-PSM. After PSM, the OS was 33.2 months (20.0-58.6) in TACE group and 38.1 months (13.8-98.1) in TARE group (p = 0.53), while PFS was 11.5 months (7.7-18.4) and 9.1 months (5.2-23.8) respectively. After PSM, post-embolization syndrome developed more in TACE group (100% vs. 75%, p = 0.002). Major adverse events were 72% in TACE group vs. 5% in TARE group (p < 0.001)., Conclusions: TARE and TACE offer comparable efficacy in managing large HCC, with TARE providing a safer profile, suggesting its consideration as a preferable initial therapeutic approach for unresectable HCC patients with tumors larger than 8 cm., (© 2024.

Semitransparent solar cells are attracting attention not only for their visual effects but also for their ability to effectively utilize solar energy. Here, we demonstrate a translucent solar cell composed of bis(trifluoromethane sulfonyl)-amide (TFSA)-doped graphene (Gr), graphene quantum dots (GQDs), and LaVO 3 . By introducing a GQDs intermediate layer at the TFSA-Gr/LaVO 3 interface, we can improve efficiency by preventing carrier recombination and promoting charge collection/separation in the device. As a result, the efficiency of the GQDs-based solar cell was 4.35%, which was higher than the 3.52% of the device without GQDs. Furthermore, the average visible transmittance of the device is 28%, making it suitable for translucent solar cells. The Al reflective mirror-based system improved the power conversion efficiency by approximately 7% compared to a device without a mirror. Additionally, the thermal stability of the device remains at 90% even after 2000 h under an environment with a temperature of 60 °C and 40% relative humidity. These results suggest that TFSA-Gr/GQDs/LaVO 3 -based cells have a high potential for practical use as a next-generation translucent solar energy power source., (© 2024 IOP Publishing Ltd.

Managed aquifer recharge (MAR) is a promising technique for enhancing groundwater resources and addressing water scarcity. Particularly, this research highlights the novelty and urgent need for MAR facilities in the Chungcheongnam-do region of South Korea as a solution to augment groundwater resources and combat water scarcity. This research encompasses a comprehensive assessment, ranging from laboratory-scale column experiments to pilot-scale tests, focusing on dissolved organic matter (DOM) characterization, natural organic matter (NOM) removal, and water quality improvement, including biological stability. In the laboratory, DOM characteristics of source water and recharged groundwater were analyzed using advanced dissolved organic characteristic tools, and their potential impacts on water quality, as well as per- and polyfluoroalkyl substances (PFASs) were assessed. DOM, total cell counts, and several PFASs with molecular weights >450 Da (particularly long-chain PFASs showing >99.9 % reduction) were effectively reduced in a laboratory-scale experiment. A laboratory-scale column study revealed that most selected PFASs were not effectively removed. Moving to the pilot-scale, a series of experiments were conducted to assess NOM removal during soil passage. Similar to the results of the laboratory-scale experiment, MAR demonstrated significant potential for reducing NOM concentrations, thus improving water quality. Regarding biological stability, assimilable organic carbon in production well (i.e., final produced water by MAR process) was lower than both two sources of surface water (e.g., SW1 and SW2). This suggests that water derived from PW (i.e., production well) exhibited biological stability, undergoing effective biodegradation by aerobic bacteria during soil passage. The findings from this study highlight the critical importance of implementing MAR techniques in regions facing water scarcity, emphasizing its potential to significantly enhance future water security initiatives., 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.

Due to limited published data, we investigated 3-year outcomes according to left ventricular ejection fraction (LVEF) in patients older and younger than 75 years with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent successful newer-generation drug-eluting stent (DES) implantation. This research analyzed the data of 4558 patients (1032 older adults [≥75 years] and 3526 younger adults [<75 years]) from the Korea Acute MI Registry-NIH. We further divided the older group based on LVEF: heart failure (HF) with reduced EF (HFrEF, ≤40%, n = 196; group A), HF with mildly reduced EF (HFmrEF, 41-49%, n = 228; group B), and HF with preserved EF (HFpEF, ≥50%, n = 608; group C). Similarly, the younger group was divided into HFrEF (group D, n = 353), HFmrEF (group E, n = 577), and HFpEF (group F, n = 2596). The primary outcome was a composite of major adverse cardiac events (MACE) at 3 years, including all-cause death, recurrent MI, any repeat revascularization, or hospitalization for HF. MACE rates were highest in the HFrEF groups (A and D), followed by the HFmrEF groups (B and E), and lowest in the HFpEF groups (C and F) for both age groups. All-cause death, cardiac death (CD), all-cause death or MI, and hospitalization for HF rates were higher in group A than in groups B and C, and higher in group D than in groups E and F. Across all LVEF categories, MACE, all-cause death, CD, and non-CD, and all-cause death or MI rates were higher in the older group. This multicenter cohort study demonstrates that older patients have higher mortality rates compared to younger patients. Additionally, MACE rates were highest in the HFrEF group, followed by the HFmrEF group, and lowest in the HFpEF group across both age groups. Further research is needed to confirm these findings., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction: This study aimed to assess the effectiveness and safety of hepatic arterial infusion chemotherapy (HAIC) in 2 groups of patients: those who receive lipiodol (referred to as the lipiodol group) and those who do not receive lipiodol (referred to as the control group)., Methods: From January 2016 through December 2023, 85 patients with advanced hepatocellular carcinoma were enrolled in this retrospective study. In total, 40 patients received HAIC with lipiodol, while 45 patients were given HAIC without lipiodol. The modified response evaluation criteria for solid tumors were used to evaluate the tumor response, which was assessed through an imaging study. The two groups were compared regarding their overall survival (OS), progression-free survival (PFS), and safety., Results: The outcomes between the lipiodol group and control group demonstrated no significant difference: the objective response rates (p = 0.066) were 32.5% and 15.6%; the disease control rates (p = 0.556) were 67.5% and 73.3%; the median OS times (p = 0.339) were 224 days and 398 days; the median PFS (p = 0.334) times were 191 days and 286 days in the lipiodol group and the control group, respectively. Adverse events also showed no significant difference between the two groups: elevation of total bilirubin (p = 0.834) rates were 40.0% and 37.8%; elevation of alanine aminotransferase (p = 0.191) percentages were 35.0% and 22.2%; and elevation of aspartate aminotransferase values (p = 0.058) were 65.0% and 44.4% in the lipiodol group and the control group, respectively., Conclusions: HAIC without lipiodol was non-inferior to HAIC with lipiodol in the clinical outcome., (© 2024 The Author(s).

Cigarette smoking is a significant risk factor for coronary artery disease. However, there is insufficient evidence regarding the long-term clinical effects of smoking in Asian populations with chronic total occlusion (CTO). This study aimed to assess the effects of smoking on 5-year (median follow-up period, 4.2 ± 1.5 [interquartile range, 4.06-5.0] years) clinical outcomes in patients with CTO lesions who underwent percutaneous coronary intervention (PCI) or medical treatment (MT). We enrolled 681 consecutive patients with CTO who underwent diagnostic coronary angiography and subsequent PCI or MT. The patients were categorized into smokers (n = 304) and nonsmokers (n = 377). The primary endpoint was major adverse cardiovascular events (MACE), including a composite of all-cause death, myocardial infarction, and revascularization over a 5-year period. Propensity score matching (PSM) analysis was performed to adjust for potential baseline confounders. After PSM analysis, two propensity-matched groups (200 pairs, n = 400) were generated, and the baseline characteristics of both groups were balanced. The smokers exhibited a higher cardiovascular risk of MACE (29.5% vs. 18.5%, p = 0.010) and non-TVR (17.5 vs. 10.5%, p = 0.044) than the nonsmokers. In a landmark analysis using Kaplan-Meier curves at 1 year, the smokers had a significantly higher rate of MACE in the early period (up to 1 year) (18.8% and 9.2%, respectively; p = 0.008) compared with the nonsmokers. The Cox hazard regression analysis with propensity score adjustment revealed that smoking was independently associated with an increased risk of MACE. These findings indicate that smoking is a strong cardiovascular risk factor in patients with CTO, regardless of the treatment strategy (PCI or MT). In addition, in the subgroup analysis, the risk of MACE was most prominently elevated in the group of smokers who underwent PCI., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Yu et al.

Background: Because no data are available, we compared the 3-year outcomes of patients with non-ST-elevation myocardial infarction (NSTEMI) based on sex and symptom-to-balloon time (SBT)., Methods: This study included 4910 patients who were divided into two groups based on SBT: SBT <48 h (n = 3,293, 67.1%) and SBT ≥48 h (n = 1,617, 32.9%). The primary outcome was all-cause death during the 3-year follow-up period. The secondary outcome was major adverse cardiac events (MACE), defined as all-cause death, recurrent myocardial infarction, or repeat coronary revascularization., Results: After adjustment, the in-hospital mortality rates for males and females in the SBT <48 h and SBT ≥48 h groups were similar. During a 3-year follow-up period, females in the SBT <48 h group had significantly higher rates of all-cause death (adjusted hazard ratio [aHR], 1.482; P = 0.006), cardiac death (CD, aHR, 1.617; P = 0.009), and MACE (aHR, 1.268; P = 0.024) than those males in the same groups. Females and males in the SBT ≥48 h group did not differ significantly in the primary and secondary outcomes. In males, the rates of all-cause death (P = 0.008) and CD (P = 0.024) were significantly higher in the SBT ≥48 h group than in the SBT <48 h group., Conclusions: This study has identified a higher 3-year mortality rate in female patients with NSTEMI and SBT <48 h compared to their male counterparts. As such, a more preventive approach may be required to reduce mortality in these female patients., Competing Interests: Declaration of competing interest None, (Copyright © 2023 Hellenic Society of Cardiology.

Aims: Considering the limited data regarding clinical outcomes of patients with non-ST-segment on the ECG elevation myocardial infarction (NSTEMI), this study compared the outcomes of patients undergoing percutaneous coronary intervention with newer-generation drug-eluting stents stratified by the presence/absence of complex lesions and symptom-to-balloon time (SBT; <48 h or ≥48 h)., Methods: We enrolled 4373 patients with NSTEMI from the Korea Acute Myocardial Infarction Registry-National Institute of Health dataset and stratified them into the complex group (2106 patients; SBT < 48 h, n  = 1365; SBT ≥48 h, n  = 741) and the noncomplex group (2267 patients; SBT < 48 h, n  = 1573; SBT ≥48 h, n  = 694). The primary outcome was the 3-year all-cause mortality rate. The secondary outcomes were any major adverse cardiac events (MACE), including cardiac death (CD), recurrent myocardial infarction, and stroke., Results: The incidence of all-cause mortality (adjusted hazard ratio, 0.656; P  = 0.009), CD ( P  = 0.037), and MACE ( P  = 0.047) in the complex group and of stroke in the noncomplex group ( P  = 0.020) were significantly lower in patients with SBT < 48 h than in those with SBT ≥48 h. Among patients with SBT < 48 h, the stroke incidence ( P  = 0.019) was higher in the complex group than in the noncomplex group, while among patients with SBT ≥48 h, the MACE incidence ( P  = 0.011) was higher in the former than in the latter., Conclusion: SBT reduction effectively decreased the 3-year mortality in patients with NSTEMI in the complex group compared with the noncomplex group., (Copyright © 2024 Italian Federation of Cardiology - I.F.C.

Statin is crucial for acute myocardial infarction (AMI) patients. However, the risk of new-onset diabetes mellitus (NODM) associated with statin is a concern. This study aimed to determine the incremental diabetogenic effects of statins according to their intensity and dose in AMI patients undergoing percutaneous coronary intervention (PCI). Among 13,104 patients enrolled in the Korea AMI Registry between 2011 and 2015, 6152 patients without diabetes mellitus (DM) who underwent PCI and received moderate-to-high-intensity atorvastatin and rosuvastatin were selected for the study. The endpoints were NODM and major adverse cardiovascular events (MACE), composite of all-cause mortality, recurrent MI, and revascularization up to 3 years. Among the participants, 3747 and 2405 received moderate- and high-intensity statins, respectively. The Kaplan-Meier curves demonstrated a higher incidence of NODM in patients with high-intensity statins than those with moderate-intensity. High-intensity statin was a significant predictor of NODM after adjusting for other co-variables (HR = 1.316, 95% CI 1.024-1.692; P < 0.032). Higher dose of rosuvastatin was associated with a higher cumulative incidence of NODM, but this dose-dependency was not apparent with atorvastatin. Cumulative incidence of MACE decreased dose-dependently only with atorvastatin. High-intensity statin was associated with a higher cumulative incidence of NODM in AMI patients, and this association was more evident in rosuvastatin. The different diabetogenic effects of the two statins provide supporting evidence for understanding the nuanced nature of statin treatment in relation to NODM., (© 2024. The Author(s).)

Background: We assessed left ventricular ejection fraction (LVEF) to compare the effects of renin-angiotensin system inhibitors (RASI) in patients with non-ST-segment elevation myocardial infarction (NSTEMI)., Methods: We categorized 4558 patients with NSTEMI as either RASI users (3752 patients) or non-users (806 patients). The 3-year patient-oriented composite outcome (POCO), which included all-cause death, recurrent myocardial infarction, any repeat revascularization, or hospitalization for heart failure (HF), was the primary outcome. To compare clinical outcomes, a multivariable-adjusted hazard ratio (aHR) was calculated after performing multicollinearity tests on all significant confounding variables (P < 0.05)., Results: Among RASI users, the aHRs for POCO, all-cause death, and cardiac death were significantly higher in the HF with reduced EF (HFrEF) subgroup than in the HF with mildly reduced EF (HFmrEF) (1.610, 2.120, and 2.489; P < 0.001, <0.001, and <0.001; respectively) and HF with preserved EF (HFpEF) (2.234, 3.920, and 5.215; P < 0.001, <0.001, and <0.001; respectively) subgroups. The aHRs for these variables were significantly higher in the HFmrEF subgroup than the HFpEF subgroup (1.416, 1.843, and 2.172, respectively). Among RASI non-users, the aHRs for these variables were significantly higher in the HFrEF subgroup than the HFmrEF (2.573, 3.172, and 3.762, respectively) and HFpEF (2.425, 3.805, and 4.178, respectively) subgroups. In three LVEF subgroups, RASI users exhibited lower aHRs for POCO and all-cause death than RASI non-users., Conclusion: In the RASI users group, the aHRs for POCO and mortality were highest in the HFrEF subgroup, intermediate in the HFmrEF subgroup, and lowest in the HFpEF subgroup., Competing Interests: Declaration of interest None., (Copyright © 2024 Hellenic Society of Cardiology.

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)., (© 2024.

Background: Although the correlation between hyperuricemia and cardiovascular disease (CVD) is well known, there have been limited data regarding the impact of hyperuricemia on long-term clinical outcomes in patients with peripheral arterial disease (PAD) after percutaneous transluminal angioplasty (PTA)., Methods: A total of 718 patients who underwent PTA for PAD were enrolled. The patients were divided into the hyperuricemia group (N = 168) and the normal group (N = 550). Hyperuricemia was defined as a uric acid level ≥ 7.0 mg/dL in men, and ≥ 6.5 mg/dL in women. The primary endpoint was major adverse cerebral and cardiovascular event (MACCE), including death, myocardial infarction (MI), any coronary revascularization, and stroke, up to 5 years. The secondary endpoint was major adverse limb event (MALE), including any repeated PTA, and target extremity surgery (TES). Inverse probability weighting (IPTW) analysis, derived from the logistic regression model, was performed to adjust potential confounders., Results: After IPTW matching analysis, compared to the normal group, the hyperuricemia group was not associated with increased MACCE but was associated with an increased incidence of MI (2.6 % vs. 0.5 %, p = 0.001), and coronary revascularization (6.7 % vs. 3.9 %, p = 0.018). Also, the hyperuricemia group was associated with a higher incidence of MALE (45.3 % vs. 28.9 %, p < 0.001), including target extremity revascularization (TER; 25.1 % vs. 15.9 %, p < 0.001), non-TER (11.5 % vs. 5.6 %, p < 0.001), and TES (22.8 % vs. 16.2 %, p = 0.002)., Conclusions: In the present study, hyperuricemia was associated with worse clinical outcomes in PAD patients following PTA during 5-year clinical follow-up. Further investigations should be made regarding the clinical benefit of controlling hyperuricemia on clinical outcomes., Competing Interests: Declaration of competing interest All authors have no financial conflicts of interest relevant to the manuscript to disclose., (Copyright © 2024 Elsevier Inc.

Previous studies have reported associations between newly diagnosed diabetes and poor outcomes after percutaneous coronary intervention (PCI), but there is limited data focusing on elderly patients (age ≥ 65). This study aimed to analyze the prevalence and clinical implications of newly diagnosed diabetes in elderly patients who underwent PCI. From 2004 to 2021, a total of 2456 elderly patients who underwent invasive PCI at Korea University Guro Hospital were prospectively enrolled and followed up for a median of five years. The primary endpoint was five-year major adverse cardiovascular events (MACE). Cox regression was used to evaluate whether newly diagnosed diabetes impacted on long-term clinical outcomes. Newly diagnosed diabetes was presented in approximately 8.1% to 10.9% of elderly patients who underwent PCI. Those who had a new diagnosis of diabetes had a higher risk of MACE than previously known diabetes (25.28% vs. 19.15%, p = 0.039). After adjusting for significant factors, newly diagnosed diabetes remained an independent predictor of MACE (HR [hazard ratio] 1.64, 95% confidence interval [CI] 1.24-2.17, p < 0.001), cardiac death (HR 2.15, 95% CI 1.29-3.59, p = 0.003) and repeat revascularization (HR 1.52, 95% CI 1.09-2.11, p = 0.013), but not for non-fatal myocardial infarction (HR 1.66, 95% CI 0.94-2.12, p = 0.081). Newly diagnosed diabetes was associated with an increased risk of 5-year MACE compared with non-diabetes and previously diagnosed diabetes in elderly patients underwent PCI. More attention should be given to those elderly newly diagnosed diabetes population., (© 2024. The Author(s).)

Individuals affected by human immunodeficiency virus (HIV) have a growing demand for coronary artery bypass grafting (CABG) due to heightened risk for cardiovascular diseases and extended life expectancy. However, CABG outcomes in HIV patients are not well-established, with insights only from small case series studies. This study conducted a comprehensive, population-based examination of in-hospital CABG outcomes in HIV patients. Patients underwent CABG were identified in National Inpatient Sample from Q4 2015-2020. Patients with age < 18 years and concomitant procedures were excluded. A 1:5 propensity-score matching was used to address preoperative group differences. Among patients who underwent CABG, 613 (0.36%) had HIV and were matched to 3119 out of 167,569 non-HIV patients. For selected HIV patients, CABG is relatively safe, presenting largely similar outcomes. After matching, HIV and non-HIV patients had comparable in-hospital mortality rates (2.13% vs. 1.67%, p = 0.40). Risk factors associated with mortality among HIV patients included previous CABG (aOR = 14.32, p = 0.01), chronic pulmonary disease (aOR = 8.24, p < 0.01), advanced renal failure (aOR = 7.49, p = 0.01), and peripheral vascular disease (aOR = 6.92, p = 0.01), which can be used for preoperative risk stratification. While HIV patients had higher acute kidney injury (AKI; 26.77% vs. 21.77%, p = 0.01) and infection (8.21% vs. 4.18%, p < 0.01), other complications were comparable between the groups., (© 2024.

Background: Most face-lift techniques greatly improve the lower face; however, techniques for lifting the midface are limited and difficult. Original deep-plane face lift is a way to lift the superficial musculoaponeurotic system and skin as a compound unit. Although it minimizes tear of the superficial musculoaponeurotic system during dissection, damage to the vascular system, and the incidence of skin necrosis, and can be easily used in secondary cases, the deep-plane face lift does not adequately improve nasolabial fold. The authors perform a modified and enhanced deep-plane face lift to improve the midface. In this article, the authors explain the effects and procedures of the method., Methods: This retrospective study included patients ( n = 632) on whom deep-plane face lift (DPF group; n = 299) and modified deep-plane face lift (M-DPF group; n = 333) was performed by a single surgeon from January of 2014 to January of 2017, and from February of 2017 to December of 2020, respectively, at a local clinic. The degree of improvement in wrinkles in the patients' nasolabial fold was assessed using the five-grade Wrinkle Severity Rating Scale (WSRS)., Results: The preoperative WSRS score was 2.95 ± 0.89 in the DPF group and 2.89 ± 0.92 in the M-DPF group. There was no significant difference in the preoperative WSRS score between the two groups ( P = 0.058). The postoperative WSRS score was 1.81 ± 0.68 in the DPF group, which was significantly greater than the 1.65 ± 0.66 found in the M-DPF group., Conclusion: This method developed by the authors that combines deep-plane face lift with deep fat compartment mobilization and zygomaticus major muscle plication is safe and directly improves the nasolabial fold and promotes a smiling expression for rejuvenation effects., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Background and Objectives: Ultimaster™, a third-generation sirolimus-eluting stent using biodegradable polymer, has been introduced to overcome long term adverse vascular events, such as restenosis or stent thrombosis. In the present study, we aimed to evaluate the 12-month clinical outcomes of Ultimaster™ stents in Korean patients with coronary artery disease., Methods: This study is a multicenter, prospective, observational registry across 12 hospitals. To reflect real-world clinical evidence, non-selective subtypes of patients and lesions were included in this study. The study end point was target lesion failure (TLF) (the composite of cardiac death, target vessel myocardial infarction [MI], and target lesion revascularization [TLR]) at 12-month clinical follow up., Results: A total of 576 patients were enrolled between November 2016 and May 2021. Most of the patients were male (76.5%), with a mean age of 66.0±11.2 years. Among the included patients, 40.1% had diabetes mellitus (DM) and 67.9% had acute coronary syndrome (ACS). At 12 months, the incidence of TLF was 4.1%. The incidence of cardiac death was 1.5%, MI was 1.0%, TLR was 2.7%, and stent thrombosis was 0.6%. In subgroup analysis based on the presence of ACS, DM, hypertension, dyslipidemia, or bifurcation, there were no major differences in the incidence of the primary endpoint., Conclusions: The present registry shows that Ultimaster™ stent is safe and effective for routine real-world clinical practice in non-selective Korean patients, having a low rate of adverse events at least up to 12 months., Competing Interests: The authors have no financial conflicts of interest., (Copyright © 2024.

Atopic dermatitis (AD), a prevalent skin condition often complicated by microbial infection, poses a significant challenge in identifying the responsible pathogen for its effective management. However, a reliable, safe tool for pinpointing the source of these infections remains elusive. In this study, a novel on-site pathogen detection that combines chemically functionalized nanotopology with genetic analysis is proposed to capture and analyze pathogens closely associated with severe atopic dermatitis. The chemically functionalized nanotopology features a 3D hierarchical nanopillar array (HNA) with a functional polymer coating, tailored to isolate target pathogens from infected skin. This innovative nanotopology demonstrates superior pathogenic capture efficiency, favorable entrapment patterns, and non-cytotoxicity. An HNA-assembled stick is utilized to directly retrieve bacteria from infected skin samples, followed by extraction-free quantitative loop-mediated isothermal amplification (direct qLAMP) for validation. To mimic human skin conditions, porcine skin is employed to successfully capture Staphylococcus aureus, a common bacterium exacerbating AD cases. The on-site detection method exhibits an impressive detection limit of 10 3 cells mL -1 . The HNA-assembled stick represents a promising tool for on-site detection of bacteria associated with atopic dermatitis. This innovative approach enables to deepen the understanding of AD pathogenesis and open avenues for more effective management strategies for chronic skin conditions., (© 2024 Wiley‐VCH GmbH.)

There is limited data on the effect of socioeconomic status (SES) on transcatheter (TAVR) and surgical aortic valve replacement (SAVR) outcomes for aortic stenosis (AS). This study conducted a population-based analysis to assess the influence of SES on valve replacement outcomes. Patients with AS undergoing TAVR or SAVR were identified in National Inpatient Sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients living in neighborhoods of income at the lowest and highest quartiles. Of 613,785 AS patients, 9.77% underwent TAVR and 10.13% had SAVR. These rates decline with lower neighborhood income levels, with TAVR/SAVR ratio also declining in lower-income areas. Excluding concomitant procedures, 58,064 patients received isolated TAVR (12,355 low-income and 15,212 high-income) and 43,694 underwent isolated SAVR (10,029 low-income and 10,811 high-income). Low-income patients, in both TAVR and SAVR, were younger but had more comorbid burden. For isolated TAVR, outcomes were similar across income groups. However, for isolated SAVR, low-income patients experienced higher in-hospital mortality (aOR = 1.44, p < 0.01), pulmonary (aOR = 1.13, p = 0.01), and renal complications (aOR = 1.14, p < 0.01). They also had more transfers, longer waits for operations, and extended hospital stays. Lower-income communities had reduced access to TAVR and SAVR, with TAVR accessibility being particularly limited. When given access to TAVR, patients from lower-income neighborhoods had mostly comparable outcomes. However, patients from low-income communities faced worse outcomes in SAVR, possibly due to delays in treatment. Ensuring equitable specialized healthcare resources including expanding TAVR access in economically disadvantaged communities is crucial., (© 2024. The Author(s).)

Background: A growing evidence on the correlation between hyperuricemia and cardiovascular disease (CVD) has been previously reported. However, there have been limited data on the impact of hyperuricemia on long-term clinical outcomes in patients with critical limb ischemia (CLI) who underwent percutaneous transluminal angioplasty (PTA)., Methods: A total of 425 peripheral artery disease patients who underwent PTA for CLI were enrolled. The patients were divided into the hyperuricemia group (n = 101) and the normal group (n = 324). The primary endpoint was major adverse cerebral and cardiovascular event (MACCE), including death, myocardial infarction, any coronary revascularization, and stroke, up to 5 years. The secondary endpoint was a major adverse limb event (MALE), including any repeated PTA, and target extremity surgery. Inverse probability weighting (IPTW) analysis, derived from the logistic regression model, was performed to adjust for potential confounders., Results: After IPTW matching analysis, compared to the normal group, the hyperuricemia group was associated with a higher incidence of MACCE (20.7% vs. 13.6%, hazard ratio [HR], 1.65; 95% confidence interval [CI], 1.15-2.38, P  = 0.006) including non-cardiac death (11.7% vs. 6.3%, HR: 1.95, 95% CI: 1.19-3.19, P  = 0.006) and MALE (47.7% vs. 36.0%, HR: 1.62, 95% CI: 1.23-2.13, P  = 0.001) including non-target extremity revascularization (15.0% vs. 6.8%, HR: 2.42, 95% CI: 1.52-3.84, P  < 0.001)., Conclusion: In the present study, hyperuricemia was associated with worse clinical outcomes in patients with CLI following PTA during 5-year clinical follow-up. Efficacy of controlling hyperuricemia in improving clinical outcomes should be evaluated in further studies., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Background: This study compared the safety and effectiveness of paclitaxel/cilostazol-eluting Cilotax stents with those of everolimus-eluting stents in patients with acute myocardial infarction. Real-world data from the Korea Acute Myocardial Infarction Registry were examined., Methods: A total of 5,472 patients with acute myocardial infarction underwent percutaneous coronary intervention with Cilotax stents (n = 212) or everolimus-eluting stents (n = 5,260). The primary end point was the 3-year rate of target lesion failure. The other end points were major adverse cardiovascular events (a composite of cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization), target vessel revascularization, and stent thrombosis. A propensity score matching analysis was performed to adjust for potential confounders by using a logistic regression model; propensity score matching generated 2 well-balanced groups (Cilotax group, n = 180; everolimus-eluting stents group, n = 170; N = 350). After propensity score matching, baseline clinical characteristics were similar between the groups., Results: After percutaneous coronary intervention, compared with the everolimus-eluting stents group, the Cilotax group more often had major adverse cardiovascular events (24.1% vs 18.5%; P = .042), myocardial infarction (8.0% vs 3.2%; P < .001), target lesion revascularization (8.0% vs 2.6%; P < .001), target vessel revascularization (11.3% vs 4.5%; P < .001), and stent thrombosis (4.7% vs 0.5%; P < .001) before matching. Even after matching, the Cilotax group had more frequent target lesion revascularization (9.4% vs 2.9%; P = .22) and stent thrombosis (5.6% vs 1.2%; P = .34)., Conclusion: In patients with acute myocardial infarction who underwent percutaneous coronary intervention, use of the Cilotax stent was associated with higher rates of target lesion revascularization, target vessel revascularization, and stent thrombosis than were everolimus-eluting stents. Use of the Cilotax dual drugeluting stent should be avoided in the treatment of myocardial infarction., (© 2024 The Authors. Published by The Texas Heart Institute®.)

Background: Racial disparities in aortic valve replacement outcomes have been established. However, the current literature lacks comprehensive studies that examine the outcomes for Native Americans, probably due to their limited population size. This study aimed to investigate whether disparities in transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) also exist for outcomes among Native Americans., Methods: Patients who underwent SAVR and TAVR were identified in National Inpatient Sample from the last quarter of 2015 to 2020. A 1:5 propensity score matching was conducted between Native Americans and Caucasians. In-hospital perioperative outcomes, length of stay, wait from admission to operation, and total hospital charge, were compared., Results: In TAVR, 51,394 (84.41 %) were Caucasians and 171 (0.28 %) were Native Americans. In SAVR, there were 50,080 (78.52 %) Caucasians and 279 (0.44 %) Native Americans. After propensity matching, no significant difference was found in post-TAVR outcomes between Native Americans and Caucasians. However, Native Americans have a higher risk of neurological complications (2.88 % vs 0.79 %, p < 0.01) with stroke being the primary contributor (2.52 % vs 0.5 %, p < 0.01), as well as a higher incidence of venous thromboembolism (1.8 % vs 0.57 %, p < 0.05) after SAVR., Conclusions: This study is the first to examine aortic valve replacement outcomes in Native Americans. Native Americans were found to be more likely to undergo SAVR than TAVR. Moreover, Native Americans were found to have five times higher stroke and three times higher VTE after SAVR. These disparities faced by Native Americans underscore the need for increased attention and targeted actions to guarantee health equity., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2023 Elsevier Inc.

Chest pain is the most common symptom of coronary artery disease (CAD) and diabetes mellitus (DM) is a well-known single strongest risk factor for cardiovascular diseases. Thus, the impact of CAD nor DM on long-term clinical effects is reported widely, but the prognostic factors of non-DM patients presenting with chest pain without significant CAD are limited. A total of 1,046 patients with chest pain without DM and significant CAD who underwent coronary angiography (CAG) and acetylcholine (ACH) provocation tests were finally enrolled. Propensity score matching and multivariate Cox-proportional hazard ratio analysis were performed to adjust for baseline potential confounders. Major adverse cardiac and cerebrovascular events (MACCE) were defined as the composite of total death, myocardial infarction (MI), revascularization, stroke, and recurrent angina. This study aimed to evaluate the long-term prognostic factors for MACCE in patients with chest pain without DM and CAD up to 5 years. Coronary artery spasm (CAS) was the most common cause of chest pain. However, long-term MACCE of CAS was not worse than those of patients with chest pain without CAS when patients with CAS had subsequent optimal antianginal medication therapy. However, a recurrent chest pain remains a problem even with continuous antianginal medication therapy. Up to 5 years, the incidence of MACCE was in 7.3%, including recurrent angina 6.9%. Dyslipidemia (HR: 2.010, 95% CI 1.166-3.466, P = 0.012), mild-moderate (30-70%) coronary stenosis (HR: 2.369, 95% CI 1.118-5.018, P = 0.024), the use of aspirin (HR: 2.885, 95% CI 1.588-5.238, P < 0.001), and the use of nitrates (HR: 1.938, 95% CI 1.094-3.433, P = 0.023) were independent risk factors for MACCE. Among the patients with chest pain without DM and significant CAD, the incidence of MACE were rare, but recurrent angina was still a challenging problem who had treated with antianginal medications., (© 2024.

Background: Due to limited data availability, we compared the 3-year outcomes of patients with acute myocardial infarction (AMI) and nonobstructive coronary arteries (MINOCA) and those with obstructive coronary arteries (MIOCA) according to renal function., Methods: From a final cohort of 10,774 patients with AMI were classified into 2 groups: the chronic kidney disease (CKD) group (estimated glomerular filtration rate <60 mL/min/1.73 m 2 , 2,854 patients; MINOCA, 123; MIOCA, 2,731) and the non-CKD group (7,920 patients; MINOCA, 256; MIOCA, 7,664). The primary outcome was the 3-year all-cause death rate, and the secondary outcomes included cardiac death (CD), non-CD death (NCD), recurrent myocardial infarction (MI), and any revascularization., Results: In both the CKD and non-CKD groups, the adjusted in-hospital mortality, 3-year all-cause death, CD, and recurrent MI rates were similar between the MINOCA and MIOCA groups, but the adjusted 3-year any revascularization rates were significantly higher in the MIOCA group than in the MINOCA group. Characteristically, in the CKD group, the adjusted 3-year NCD rate (P = 0.032) was higher in the MINOCA group than in the MIOCA group, and sepsis was the main cause of NCD in this group. In both the MINOCA and MIOCA groups, all-cause death and NCD were significantly higher in the CKD group than in the non-CKD group., Conclusions: Regardless of renal function, the MINOCA and MIOCA groups had comparable mortality rates. However, patients with MINOCA and CKD had higher NCD rates. Close monitoring of renal function and enhanced strategies are required to reduce mortality in patients with MINOCA., (Copyright © 2023 Hellenic Society of Cardiology. Published by Elsevier Inc.

Background: The selection of an efficacious treatment modality for patients with hepatocellular carcinoma (HCC) diagnosed as refractory to transarterial chemoembolization (TACE) presents numerous challenges. In addition to systemic therapies, hepatic arterial infusion chemotherapy (HAIC) may serve as an alternative option. However, it is imperative to identify patients who are appropriate candidates for HAIC to confer a survival benefit. Our study aimed to evaluate the impact of the number of TACE sessions prior to HAIC treatment and the addition of TACE during HAIC on the survival of HCC patient's refractory to TACE., Methods: This retrospective study included 82 patients with HCC refractory to TACE (mean age 60.5 years, 75 males). Survival analysis was conducted using the Kaplan-Meier method, with comparison between two groups via the log-rank test; the Cox regression model was utilized to identify factors influencing survival., Results: The overall response rate (ORR) was observed to be 29.3%, with a disease control rate (DCR) of 56.1%. Patients receiving more than four TACE sessions prior to HAIC exhibited a significantly poorer survival prognosis compared to those receiving fewer than four TACE sessions, with a hazard ratio (HR) of 0.151 (P=0.02). The median overall survival (OS) was markedly different, being 3.4 (range, 0.5-13.6) months for the former group and 14 (range, 8.5-19.5) months for the latter (P=0.01). Furthermore, patients undergoing additional TACE while receiving HAIC treatment demonstrated improved survival outcomes compared to those who did not, with an HR of 0.491 (P=0.02); the respective OS for these groups was 14 (range, 3.6-14.4) and 6.7 (range, 2.8-11) months (P=0.02)., Conclusions: HAIC can be a suitable alternative treatment for HCC patient's refractory to TACE. For those with a history of more than 4 TACE sessions, other alternative treatments should be considered. The addition of TACE during HAIC treatment may extend patient OS time, provided it is balanced with maintaining safe liver function., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jgo.amegroups.com/article/view/10.21037/jgo-23-1006/coif).

This study aimed to assess the effects of microbial additives that produce antimicrobial and digestive enzymes on the growth performance, blood metabolites, fecal microflora, and carcass characteristics of growing-finishing pigs. A total of 180 growing-finishing pigs (Landrace × Yorkshire × Duroc; mixed sex; 14 weeks of age; 58.0 ± 1.00 kg) were then assigned to one of three groups with three repetitions (20 pigs) per treatment for 60 days of adaptation and 7 days of collection. Dietary treatments included 0, 0.5, and 1.0% microbial additives in the basal diet. For growth performance, no significant differences in the initial and final weights were observed among the dietary microbial additive treatments, except for the average daily feed intake, average daily gain, and feed efficiency. In terms of blood metabolites and fecal microflora, immunoglobulin G (IgG), blood urea nitrogen, blood glucose, and fecal lactic acid bacteria count increased linearly, and fecal E. coli counts decreased linearly with increasing levels of microbial additives but not growth hormones and Salmonella . Carcass quality grade was improved by the microbial additive. In addition, carcass characteristics were not influenced by dietary microbial additives. In conclusion, dietary supplementation with 1.0% microbial additive improved average daily gain, feed efficiency, IgG content, and fecal microflora in growing-finishing pigs.

Previous studies have reported the association between myocardial infarction (MI) and air pollution (AP). However, limited information is available regarding the long-term effects of AP on the relative incidence rates of ST-elevation MI (STEMI) and Non-ST-elevation MI (NSTEMI). We investigated the association between long-term exposure to AP and the incidence of STEMI. Between January 2006 and December 2015, a total of 45,619 eligible patients with Acute Myocardial Infarction (AMI) were enrolled in the Korea Acute MI Registry (KAMIR) and KAMIR-National Institutes of Health. Mixed-effect regression models were used to examine the association between the annual average ambient AP before MI onset and the incidence of STEMI, and to evaluate the association of AP with the incidence of in-hospital cardiogenic shock. After mixed-effect regression model analysis, particulate matter (PM) 10 µm or less in diameter (PM 10 ) was associated with increased incidence of STEMI compared with NSTEMI (odds ratio [OR] 1.009, 95% Confidence Interval [CI] 1.002-1.016; p = 0.012). For in-hospital cardiogenic shock complication, PM 10 and SO 2 were associated with increased risk, PM 10 (OR 1.033, 95% CI 1.018-1.050; p < 0.001), SO 2 (OR 1.104, 95% CI 1.006-1.212; p = 0.037), respectively. Policy-level strategies and clinical efforts to reduce AP exposure are necessary to prevent the incidence of STEMI and severe cardiovascular complications., (© 2024. The Author(s).)

Background: Recent trials have shown that both the extent of glycated hemoglobin reduction and the duration of enhanced glycemic control are major factors that may affect cardiovascular outcome results. We aimed to investigate the impact of metformin (MET) combined with dipeptidyl peptidase-4 (DPP4) inhibitors or sulfonylureas (SU) on long-term clinical outcomes in patients with acute myocardial infarction (AMI) and type 2 diabetes mellitus (DM)., Methods: This study was a prospective cohort trial. From November 2011 to December 2015, a total of 13,104 AMI patients were consecutively enrolled from the Korea AMI registry-National Institutes of Health. The patients were divided into the MET + DPP4 inhibitors group and the MET + SU group. The primary endpoint, major adverse cardiac events (MACE), was defined as the composite of all-cause death, recurrent myocardial infarction (MI), and any repeat revascularization up to 3-year follow-up. To adjust baseline potential confounders, an inverse probability weighting (IPTW) analysis was performed., Results: Baseline well-matched two groups were generated (the MET + DPP4 inhibitors group, n=468 and the MET + SU group, n=468). During 3-year clinical follow-up, the cumulative incidence of MACE between the two groups was not significantly different after adjustment (16.8% for MET + DPP4 inhibitors group vs. 19.4% for MET + SU group, P=0.302). However, the MET + DPP4 inhibitors group was associated with reduced risk of MI [1.3% vs. 4.9%; hazard ratio (HR): 0.228, 95% confidence interval (CI): 0.090-0.580, P=0.001] than the MET + SU group., Conclusions: In patients with AMI and type 2 DM, the use of MET combined with DPP4 inhibitors was associated with reduced incidence of recurrent MI than MET combined with SU during 3-year follow-up., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://cdt.amegroups.com/article/view/10.21037/cdt-23-349/coif).

Characterization of the elemental distribution of samples with rough surfaces has been strongly desired for the analysis of various natural and artificial materials. Particularly for pristine and rare analytes with micrometer sizes embedded on specimen surfaces, non-invasive and matrix effect-free analysis is required without surface polishing treatment. To satisfy these requirements, we proposed a new method employing the sequential combination of two imaging modalities, i.e., microenergy-dispersive X-ray fluorescence (micro-XRF) and Raman micro-spectroscopy. The applicability of the developed method is tested by the quantitative analysis of cation composition in micrometer-sized carbonate grains on the surfaces of intact particles sampled directly from the asteroid Ryugu. The first step of micro-XRF imaging enabled a quick search for the sparsely scattered and micrometer-sized carbonates by the codistributions of Ca 2+ and Mn 2+ on the Mg 2+ - and Fe 2+ -rich phyllosilicate matrix. The following step of Raman micro-spectroscopy probed the carbonate grains and analyzed their cation composition (Ca 2+ , Mg 2+ , and Fe 2+ + Mn 2+ ) in a matrix effect-free manner via the systematic Raman shifts of the lattice modes. The carbonates were basically assigned to ferroan dolomite bearing a considerable amount of Fe 2+ + Mn 2+ at around 10 atom %. These results are in good accordance with the assignments reported by scanning electron microscopy-energy-dispersive X-ray spectroscopy, where the thin-sectioned and surface-polished Ryugu particles were applicable. The proposed method requires neither sectioning nor surface polishing; hence, it can be applied to the remote sensing apparatus on spacecrafts and planetary rovers. Furthermore, the non-invasive and matrix effect-free characterization will provide a reliable analytical tool for quantitative analysis of the elemental distribution on the samples with surface roughness and chemical heterogeneity at a micrometer scale, such as art paintings, traditional crafts with decorated shapes, as well as sands and rocks with complex morphologies in nature.

Background: Diabetes mellitus (DM) is a significant factor in increased mortality rates among patients with acute myocardial infarction (AMI), but research on its impact on the long-term outcomes in patients with MI with nonobstructive coronary arteries (MINOCA) is limited. Thus, a comparison of the 3-year clinical outcomes between the DM and non-DM groups among patients with MINOCA was undertaken., Methods: From the Korea AMI Registry-National Institute of Health dataset, 10,774 AMI patients were enrolled. After applying the exclusion criteria, 379 patients with MINOCA were included. The primary clinical outcomes were major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, recurrent myocardial infarction (MI), repeat coronary revascularization, and stroke. The secondary outcomes were the individual components of MACCE., Results: The adjusted hazard ratios for 3-year MACCE (2.287, p = 0.010), all-cause death (2.845, p = 0.004), and non-cardiac death (non-CD, 3.914, p = 0.008) were higher in the DM group than in the non-DM group. It is speculated that the higher non-CD rate in the MINOCA group is attributable to a higher proportion of patients with non-ST-segment elevation MI in the total study population. The CD, recurrent MI, revascularization, and stroke rates were similar between the DM and non-DM groups. DM, advanced age, cardiopulmonary resuscitation on admission, and non-use of statin medications were significant predictors of MACCE., Conclusions: In this study involving patients with MINOCA, the DM group exhibited a higher 3-year mortality rate than the non-DM group. Thus, DM demonstrated a hazardous effect even in patients with MINOCA.

Introduction: The effectiveness of transarterial chemoembolization (TACE) in treating hepatocellular carcinoma (HCC) has been well established. The differential impacts of drug-eluting bead TACE (DEB-TACE) as opposed to conventional TACE (cTACE) on vascular changes, such as arterial-portal venous shunts (APSs), have been recognized. However, their subsequent effects on treatment outcomes have not been fully explored. This study aims to identify risk factors associated with the occurrence of APS in HCC patients treated with DEB-TACE and to evaluate its impact on patient survival., Methods: A retrospective analysis was conducted from January 2012 to December 2018 including 74 HCC patients receiving DEB-TACE as initial treatment and a 1:1 cTACE. Kaplan-Meier analysis estimated overall survival (OS) and progression-free survival (PFS). Logistic regression identified significant risk factors for APS occurrence after DEB-TACE., Results: APS incidence was significantly higher after DEB-TACE than cTACE (46.0% vs. 16.2%, p &lt; 0.001). There was no significant difference in median OS between APS and non-APS groups after DEB-TACE: 50 months (24.6-75.4) versus 26.9 months (19.5-43.2), p = 0.111; median PFS was 15.6 months (4.1-27.1) and 9.5 months (6.8-12.1) for the two groups, respectively, p = 0.065. Risk factors for APS occurrence after DEB-TACE were more than two feeding arteries (OR: 7.25, 95% CI: 1.82-28.95, p = 0.005) and non-selective embolization (OR: 8.02, 95% CI: 2.30-27.95, p = 0.001)., Conclusion: APS occurrence was higher in DEB-TACE-treated HCC patients, but it did not significantly affect OS and PFS. More than two feeding arteries and non-selective embolization were significant risk factors for APS occurrence after DEB-TACE., (© 2024 The Author(s). Published by S. Karger AG, Basel.)

Background: We evaluated the effect of delayed hospitalization (symptom-to-door time [STD] ≥ 24 h) on 3-year clinical outcomes according to renal function in patients with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing new-generation drug-eluting stent (DES) implantation., Methods: A total of 4513 patients with NSTEMI were classified into chronic kidney disease (CKD) (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73 m², n = 1118) and non-CKD (eGFR ≥ 60 mL/min/1.73 m², n = 3395) groups. They were further sub-classified into groups with (STD ≥ 24 h) and without (STD < 24 h) delayed hospitalization. The primary outcome was the occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, recurrent myocardial infarction, any repeat coronary revascularization, and stroke. The secondary outcome was stent thrombosis (ST)., Results: After multivariable-adjusted and propensity score analyses, the primary and secondary clinical outcomes were similar in patients with or without delayed hospitalization in both CKD and non-CKD groups. However, in both the STD < 24 h and STD ≥ 24 h groups, MACCE (p < 0.001 and p < 0.006, respectively) and mortality rates were significantly higher in the CKD group than in the non-CKD group. However, ST rates were similar between the CKD and non-CKD groups and between the STD < 24 h and STD ≥ 24 h groups., Conclusions: Chronic kidney disease appears to be a much more important determinant of MACCE and mortality rates than STD in patients with NSTEMI.

Importance: The strategy using structural homology with the help of structure prediction by AlphaFold was very successful in finding potential targets for the frhAGB -encoded hydrogenase of Thermococcus onnurineus NA1. The finding that the hydrogenase can interact with FdhB to reduce the cofactor NAD(P) + is significant in that the enzyme can function to supply reducing equivalents, just as F 420 -reducing hydrogenases in methanogens use coenzyme F 420 as an electron carrier. Additionally, it was identified that T. onnurineus NA1 could produce formate from H 2 and CO 2 by the concerted action of frhAGB -encoded hydrogenase and formate dehydrogenase Fdh3., Competing Interests: The authors declare no conflict of interest.

Objective: To evaluate the efficacy of policresulen for the treatment of hypergranulation., Method: This was a retrospective study of patients with percutaneous catheters. Inpatients from two hospitals and those from outpatient clinics were included. Approximately 2ml of 50% policresulen solution was applied to hypergranulation tissue, which was then immediately pressed with gauze for 1-3 minutes using light pressure. When haemostasis was achieved and the granulation tissue size decreased, the procedure was terminated., Results: A total of eight patients (four females and four males) were included in this study. Effective haemostasis was achieved in all patients. The size of the hypergranulation tissue decreased with policresulen treatment, and resolved completely in one patient. There were no complications. Hypergranulation tissue recurred in one patient. Haemostasis was successfully achieved after repeated procedures., Conclusion: The findings of this study showed policresulen to be an inexpensive, easy treatment for hypergranulation at catheter insertion sites.

This prospective, multicenter, randomized study aimed to compare the 1-year clinical outcomes after primary stenting with self-expanding bare metal nitinol stent (SENS) and plain old balloon angioplasty (POBA) in patients with critical limb ischemia (CLI) and below-the-knee (BTK) lesions. Overall, 119 patients with CLI and BTK lesions were randomized to POBA alone (POBA group, 61 patients) or primary stenting with SENS (stenting group, 58 patients) after achieving acceptable POBA results in target BTK lesions. Clinical outcomes including amputation and revascularization rates were prospectively compared for 1 year. After 1 year, similar incidence rates of individual clinical endpoints, including cardiac death (6.5% vs. 5.1%, p > 0.999), myocardial infarction (1.6% vs. 0.0%, p > 0.999), repeat revascularization (19.6% vs. 18.9%, p = 0.922), target lesion revascularization (13.1% vs. 17.2%, p = 0.530), and amputation (4.9% vs. 0.0%, p = 0.244), were observed. POBA appeared to have acceptable treatment outcomes compared with primary stenting with SENS after 1 year in CLI patients with BTK lesions undergoing percutaneous transluminal angioplasty (PTA)., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Ahn et al.

Studies of material returned from Cb asteroid Ryugu have revealed considerable mineralogical and chemical heterogeneity, stemming primarily from brecciation and aqueous alteration. Isotopic anomalies could have also been affected by delivery of exogenous clasts and aqueous mobilization of soluble elements. Here, we show that isotopic anomalies for mildly soluble Cr are highly variable in Ryugu and CI chondrites, whereas those of Ti are relatively uniform. This variation in Cr isotope ratios is most likely due to physicochemical fractionation between 54 Cr-rich presolar nanoparticles and Cr-bearing secondary minerals at the millimeter-scale in the bulk samples, likely due to extensive aqueous alteration in their parent bodies that occurred [Formula: see text] after Solar System birth. In contrast, Ti isotopes were marginally affected by this process. Our results show that isotopic heterogeneities in asteroids are not all nebular or accretionary in nature but can also reflect element redistribution by water.

Purpose: To compare tumor perfusion on cone-beam computed tomography (CBCT) after hepatic artery infusion port implantation with the tumor response to hepatic arterial infusion chemotherapy (HAIC) in patients with hepatocellular carcinoma (HCC)., Methods: This retrospective study was conducted in patients with advanced HCC treated with HAIC from 2015 to 2020. We performed CBCT with contrast injection via a port on the day following implantation. We classified tumor perfusion on CBCT into three groups: hyperperfusion, isoperfusion, and hypoperfusion. We also evaluated tumor response to HAIC on follow-up images using RECIST 1.1 and compared it with tumor perfusion on CBCT., Results: This study included 206 tumors in 193 patients (mean: 60.5 years) with HCC. There were 100 hyperperfusion tumors (48.5%), 92 isoperfusion tumors (44.7%), and 14 hypoperfusion tumors (6.8%). The tumor response to HAIC included 10 tumors with a complete response (CR) (4.9%), 66 tumors with a partial response (32%), 60 tumors with stable disease (29.1%), and 70 tumors with progressive disease (34%). Hyperperfusion tumors had a 65% objective response rate (ORR) and a 92% disease control rate (DCR). Isoperfusion tumors had a 12% ORR and a 46.8% DCR, while hypoperfusion tumors had a 0% ORR and a 7.1% DCR. A CR was shown only in hyperperfusion tumors. The ORR and DCR of the three groups were different, with statistical significance ( P < 0.001)., Conclusion: Hyperperfusion tumors on CBCT showed a better tumor response to HAIC, with a 65% ORR in patients with HCC. Tumor perfusion on CBCT after implantation of the hepatic arterial infusion port was associated with the tumor response to HAIC.

Background: Previous studies reported that compared to conventional dual antiplatelet therapy (DAT; aspirin + clopidogrel), triple antiplatelet therapy (TAT), involving the addition of cilostazol to DAT, had better clinical outcomes in patients with ST-elevation myocardial infarction (STEMI). However, the optimal duration of TAT is yet to be determined., Methods: In total, 985 patients with STEMI who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) were prospectively enrolled in 15 PCI centers in South Korea and China. We randomly assigned patients into 3 groups: DAT (aspirin and clopidogrel for 12 months), TAT 1M (aspirin, clopidogrel, and cilostazol for 1 month), and TAT 6M (aspirin, clopidogrel, and cilostazol for 6 months). The primary endpoint was 1-year major adverse cardiovascular events (MACEs), defined as a composite of all-cause death, recurrent myocardial infarction, stroke, or repeat revascularization., Results: The primary endpoint did not differ among the 3 groups (8.8% in DAT, 11.0% in TAT 1M, and 11.6% in TAT 6M; hazard ratio for TAT 1M vs DAT, 1.302; 95% confidence interval [CI], 0.792-2.141; P = .297; hazard ratio for TAT 6M vs DAT, 1.358; 95% CI, 0.829-2.225; P = .225). With respect to in-hospital outcomes, more bleeding events occurred in the TAT group than in the DAT group (1.3% vs 4.7% vs 2.6%, P = .029), with no significant differences in major bleeding events. Additionally, the TAT group had a higher incidence of headaches (0% vs 1.6% vs 2.6%, P = .020)., Conclusions: The addition of cilostazol to DAT did not reduce the incidence of 1-year MACEs compared with DAT alone. Instead, it may be associated with an increased risk of drug intolerance and side effects, including in-hospital bleeding and headaches., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Background: Lesion length is related to worse clinical outcomes following percutaneous coronary intervention (PCI) for the treatment of chronic total occlusion (CTO). However, the data to confirm the association between extremely long lesions and clinical hard endpoints have been limited. Therefore, we investigated the impact of extremely long CTO lesions (≥50 mm, treated lesion length) on the long-term clinical outcomes following successful PCI., Methods: A total of 333 consecutive patients with CTO who underwent successful PCI with drug-eluting stents (DESs) were allocated to either the extremely long or the short CTO group according to their CTO lesion length. The 5-year clinical outcomes were compared between the two groups. The incidence of myocardial infarction, cardiac death (CD), revascularization, and major adverse cardiovascular events (MACE) was higher in the extremely long CTO group. The 5-year clinical outcomes were analyzed using the Cox hazard ratio (HR) model., Results: In the entire study population, the extremely long CTO lesion was an independent predictor for higher rate of revascularization, MACE, CD, or mortality., Conclusions: In our study, CTO patients with extremely long lesions (≥50 mm) who underwent successful PCI were associated with a higher risk of worse long-term clinical outcomes, including hard clinical endpoints such as CD and mortality even in the DESs era., (© 2023 Wiley Periodicals LLC.)

In the absence of available data, we evaluated the effects of delayed hospitalization (symptom-to-door time [SDT] ≥ 24 h) on major clinical outcomes after new-generation drug-eluting stent implantation in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and complex lesions. In total, 4373 patients with NSTEMI were divided into complex (n = 2106) and non-complex (n = 2267) groups. The primary outcome was the 3-year rate of major adverse cardiac events (MACE), defined as all-cause death, recurrent MI, and any repeat revascularization. Secondary outcomes included the individual MACE components. In the complex group, all-cause death (adjusted hazard ratio [aHR], 1.752; p = 0.004) and cardiac death (aHR, 1.966; p = 0.010) rates were significantly higher for patients with SDT ≥ 24 h than for those with SDT < 24 h. In the non-complex group, all patients showed similar clinical outcomes. Patients with SDT < 24 h (aHR, 1.323; p = 0.031) and those with SDT ≥ 24 h (aHR, 1.606; p = 0.027) showed significantly higher rates of any repeat revascularization and all-cause death, respectively, in the complex group than in the non-complex group. Thus, in the complex group, delayed hospitalization was associated with higher 3-year mortalities., (© 2023. Springer Nature Limited.)

Background: In patients with an acute aortoceliac angle, the diagnostic catheter often fails to enter the common hepatic artery., Purpose: To retrospectively evaluate the impact of aortoceliac angle on the implantation of a port-catheter system via a femoral approach for hepatic arterial infusion chemotherapy (HAIC) in patients with advanced hepatocellular carcinoma (HCC)., Material and Methods: A total of 399 patients with advanced HCC underwent percutaneous implantation of a port-catheter system for HAIC. Among these patients, 383 underwent successful implantation via a femoral artery approach (success group). In 16 patients, port-catheter systems were implanted via a subclavian artery approach (failure group) after failure of the initial attempt via the femoral artery due to failed catheter tip fixation to the gastroduodenal artery. We statistically analyzed aortoceliac angle, ostial celiac stenosis, sex, age, weight, height, and body mass index (BMI) between groups., Results: The average aortoceliac angle, weight, and BMI were significantly different between the two groups ( P  < 0.001, P  = 0.02, P  < 0.001, respectively). Among them, only the aortoceliac angle was a significant risk factor in logistic regression analysis. The smaller the aortoceliac angle, the more often the femoral approach failed ( P  < 0.001, odds ratio = 0.817, 95% confidence interval = 0.752-0.887). There were no significant differences in ostial celiac stenosis, sex, or age between the two groups ( P  = 0.549, 0.056, 0.173, and 0.773, respectively)., Conclusion: For patients with an acute aortoceliac angle, the femoral approach is likely to fail. A subclavian artery approach should be preferentially considered for percutaneous implantation of a port-catheter system in such patients.
