Annual Research Review: Mapping the multifaceted approaches and impacts of adverse childhood experiences - an umbrella review of meta-analyses.

Adverse childhood experiences (ACEs) significantly impact lifelong health and well-being. Despite extensive research, a comprehensive understanding of ACEs' multifaceted impacts continues to be challenging to achieve. This study synthesizes meta-analytic evidence to provide a comprehensive view of ACEs' effects, addressing various approaches to conceptualizing ACEs and their diverse outcomes. Employing an umbrella synthesis methodology, this review integrated findings from 99 meta-analyses involving 592 effect sizes. We examined ACEs through specificity, lumping, dimensional, and child maltreatment-centric approaches, assessing their impact across six domains: biological system dysregulation, neuropsychological impairments, physical health complications, mental health conditions, social and behavioral challenges, and criminal justice involvement. The findings reveal a small to moderate overall effect size of ACEs across outcome domains. Specific ACE approaches exhibited varying impact levels, with notable differences in effects on mental health, social/behavioral issues, and criminal justice involvement. When ACEs were aggregated without distinguishing between different types, but with consideration of their cumulative effects, adverse outcomes were significantly exacerbated. The child maltreatment-centric approach consistently demonstrated substantial effects across all evaluated domains. This review underscores the heterogeneity in ACEs' impacts, influenced by the type of ACE and specific outcomes considered. It highlights the necessity for comprehensive approaches to understanding, preventing, and mitigating the effects of ACEs. These insights are vital for developing targeted interventions and informing policy-making, emphasizing the complexity and varied nature of ACEs' influence on individual development and societal well-being.

Identification of TLR2/4-mediated phagocytosis and immune response activation pathways by vacuoles isolated from Saccharomyces cerevisiae.

The vacuoles of the yeast Saccharomyces cerevisiae are closely related to mammalian lysosomes and play a role in macromolecular degradation due to the hydrolytic enzymes present inside. The vacuoles also regulate osmotic pressure and control cellular homeostasis. In previous results, vacuoles were shown to activate the immune response of macrophages by promoting the production of immune-mediated transporters nitric oxide (NO), reactive oxygen species (ROS), and pro-inflammatory cytokines. In this study, the effects of vacuoles on the phagocytosis activity of RAW264.7 cells and their potential as immune enhancers were evaluated, and receptors capable of recognizing vacuoles were examined. An investigation using the phagocytes assay showed that phagocytosis activity increased by the vacuole. Besides, after treatment with TLR2/4 inhibitor, the expression of pro-inflammatory cytokines by vacuoles was significantly reduced and the inducible nitric oxide synthase (iNOS) protein was also significantly reduced. However, treatment with a TLR2 inhibitor did not reduce the production of interleukin-6 (IL)-6, a pro-inflammatory cytokine. As a result of confirming the activation of TLR2/4 using Western blot and immunofluorescence (IF), the TLR2/4 protein expression and fluorescence intensity increased depending on the concentration of vacuoles. Yeast vacuoles significantly upregulate protein expression of p-p65/p-p38 MAPKs. In summary, the vacuoles isolated from S. cerevisiae in macrophages have increased phagocytic ability at a concentration of 20 (µg/ml) and can function as immune-enhancing agent suggesting that TLR2/4 mediated the p38 MAPK/nuclear factor kappa B signaling pathway.

Drug-coated balloon-based versus drug-eluting stent-only revascularization in patients with diabetes and multivessel coronary artery disease.

BACKGROUND: Data on drug-coated balloon (DCB) treatment in the context of diabetes mellitus (DM) and multivessel coronary artery disease (CAD) are limited. We aimed to investigate the clinical impact of DCB-based revascularization on percutaneous coronary intervention (PCI) in patients with DM and multivessel CAD. METHODS: A total of 254 patients with multivessel disease (104 patients with DM) successfully treated with DCB alone or combined with drug-eluting stent (DES) were retrospectively enrolled (DCB-based group) and compared with 254 propensity-matched patients treated with second-generation DES from the PTRG-DES registry (n = 13,160 patients) (DES-only group). Major adverse cardiovascular events (MACE) comprised cardiac death, myocardial infarction, stroke, stent or target lesion thrombosis, target vessel revascularization, and major bleeding at 2 years. RESULTS: The DCB-based group was associated with a reduced risk of MACE in patients with DM (hazard ratio [HR] 0.19, 95% confidence interval [CI] 0.05-0.68, p = 0.003], but not in those without DM (HR 0.52, 95% CI 0.20-1.38, p = 0.167) at the 2-year follow-up. In patients with DM, the risk of cardiac death was lower in the DCB-based group than the DES-only group, but not in those without DM. In both patients with or without DM, the burdens of DES and small DES (less than 2.5 mm) used were lower in the DCB-based group than in the DES-only group. CONCLUSIONS: In multivessel CAD, the clinical benefit of a DCB-based revascularization strategy appears to be more evident in patients with DM than in those without DM after 2 years of follow-up.

Healing and stent coverage with the new ultrathin sirolimus-eluting stent with abluminal biodegradable polymer.

BACKGROUND: Genoss drug-eluting stent (DES) (Genoss Company Limited) is a new ultrathin sirolimus-eluting stent with an abluminal biodegradable polymer and a cobalt-chromium platform. AIMS: The aim of this study was to evaluate vascular healing and neointimal coverage after implantation of the Genoss DES using optical coherence tomography (OCT) 6 months postimplantation. METHODS: From August 22, 2019 to June 17, 2020, this multicenter, observational, investigator-initiated study enrolled 20 patients who underwent OCT examination 6 months after Genoss DES implantation and provided informed consent. An analyst, blinded to the patients' and procedural information analyzed OCT images at an independent core laboratory. RESULTS: Of the 20 patients, 19 with 27 stents in 21 lesions from 21 vessels were included in the analysis, while one patient withdrew consent and was unwilling to undergo follow-up OCT. OCT analysis was performed 204.4 ± 31.9 days after Genoss DES implantation. A total of 4285 stent struts from 661 cross-sections were analyzed. Strut tissue coverage was observed in 98.7 ± 4.3% of struts, with 0.1 ± 1.2% malapposed struts per lesion. The mean thickness of neointimal hyperplasia (NIH) on the covered struts was 0.12 ± 0.04 mm. CONCLUSIONS: Six months after stent implantation, most Genoss DES struts were covered with a thin layer of NIH that was evenly distributed along the stent length. This pilot study evaluated the outcomes of 6 months dual antiplatelet therapy in the context of ultrathin strut stents, providing insight into developing ethical standards and a scientific foundation for conducting an adequately designed clinical trial.

Yeast vacuolar enzymes as novel hatching inhibitors for aquatic organisms, Daphnia magna and Danio rerio eggs.

Concerns over the spread of non-native species in aquatic environments have led to the need for effective methods to prevent and control their spread while protecting native species. This study investigated the potential of yeast vacuolar enzymes as a natural hatching inhibitor for controlling aquatic organisms. Hatching experiments with Daphnia magna eggs demonstrated that exposure to yeast vacuole enzymes inhibited hatching in a concentration-dependent manner, suggesting their potential as an effective inhibitor of egg hatching in aquatic organisms. Interestingly, the protease used for comparative purposes did not inhibit hatching, but instead increased the mortality of hatched D. magna. Additionally, chorionic changes were observed in non-hatched D. magna eggs and zebrafish eggs exposed to yeast vacuole enzymes, suggesting that the enzyme can alter the chorion and interfere with hatching. These findings suggest that yeast vacuolar enzymes may be a promising and natural management tool for controlling the spread of harmful aquatic organisms, and further research is warranted to explore their potential for species-specific control.

Sex-Based Outcomes of P2Y12 Inhibitor Monotherapy After Three Months of Dual Antiplatelet Therapy in Patients Undergoing Percutaneous Coronary Intervention.

BACKGROUND: In patients undergoing percutaneous coronary intervention (PCI) in the SMART-CHOICE trial, P2Y12 inhibitor monotherapy after three months of dual antiplatelet therapy (DAPT) achieved clinical outcomes comparable to those of 12 months of DAPT. Nonetheless, the effects of sex on these outcomes remain unknown. METHODS: This open-label, non-inferiority, randomized study, conducted in 33 hospitals in South Korea, included 2,993 patients undergoing PCI with drug-eluting stents. Patients were randomly assigned to receive DAPT (aspirin plus a P2Y12 inhibitor) for three months then P2Y12 inhibitor alone for nine months, or DAPT for the entire 12 months. The primary endpoints were major adverse cardiac and cerebrovascular events (a composite of all-cause death, myocardial infarction, or stroke) 12 months after the index procedure. The bleeding endpoints were Bleeding Academic Research Consortium (BARC) bleeding types 2 to 5. RESULTS: Of the patients, 795 (26.6%) were women, who were older and had a higher prevalence of hypertension, diabetes, and dyslipidemia than men. The sexes exhibited comparable primary endpoints (adjusted hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.55-1.55; P = 0.770) and bleeding endpoints (adjusted HR, 1.07; 95% CI, 0.63-1.81; P = 0.811). P2Y12 inhibitor monotherapy vs DAPT was associated with lower risk of BARC type 2 to 5 bleeding in women (adjusted HR, 0.40; 95% CI, 0.16-0.98; P = 0.045) but the difference was not statistically significant when using the Bonferroni correction. The primary endpoints were similar between treatment groups in both sexes. CONCLUSION: In both sexes undergoing PCI, P2Y12 inhibitor monotherapy after three months of DAPT achieved similar risks of the primary endpoints and the bleeding events compared with prolonged DAPT. Therefore, the benefits of early aspirin withdrawal with ongoing P2Y12 inhibitors may be comparable in women and men. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02079194.

Endodontic retreatment of a calcified anterior tooth using a 3D-printed endodontic guide.

The treatment of teeth with severely calcified canals is a difficult procedure for clinicians. Procedural accidents such as drill path deviation or perforation of the root canal often occur. 3D-printed directional guides made using CBCT and CAD/CAM can help the clinician to accurately drill in the original root canal direction. Furthermore, chairside operating times and excessive loss of tooth structure are reduced, and the risk of perforation is avoided. The present case report describes two cases of calcified root canals with path deviations that were retreated utilizing a guided endodontic technique.

Revisiting the Empirical Status of Social Learning Theory on Substance Use: A Systematic Review and Meta-Analysis.

Background: Despite ample empirical research testing components of Akers' Social Learning Theory (SLT) on substance use, no research to date has attempted to synthesize the empirical evidence. Objectives: The purpose of this article is to synthesize prior research that has examined the utility of SLT for predicting specific types of substance use, both legal and illegal. Methods: Using a systematic review and meta-analysis, the current study estimated the effect size results from 83 primary studies published between 1974 and 2018 that had empirically tested concepts of Akers' SLT regarding substance use. In addition, moderator analyses examined variations in effect sizes across measurement constructs and among specific types of substance use. Results: Results indicated medium-sized weighted mean effect size estimates for SLT in relation to substance use. Regarding conceptualization of SLT, measures of Differential Association produced the strongest effect size estimates. Moderator analyses also revealed that mean effect size estimates were largest for soft drugs, for studies conducted in the context of the United States, and for adult samples. Conclusions: The authors conclude that SLT constructs may be better suited for explaining soft drug use than hard drug use. Given the relatively sparse primary research that has controlled for temporal ordering, collected data from multiple differential associates, or considered opportunity effects, caution in the interpretation of synthesis results is warranted.

Antenatal sonographic features of persistent extrahepatic vitelline vein aneurysm confused with umbilical vein varix.

Background: The persistent vitelline vein is a portal venous system malformation arising during the embryonic period. These abnormal blood vessels frequently thrombose and can lead superior mesenteric vein obstruction or portal hypertension. Case report: We visualized a fetal intra-abdominal cystic mass with turbulent flow on prenatal ultrasound at 28 weeks' gestation. Initially diagnosed as an umbilical vein varix, it was later determined to be an extrahepatic persistent vitelline vein with an internal thrombus by postnatal ultrasound. It was successfully surgically excised. Conclusion: When an abnormal abdominal vascular structure near the umbilicus is found during prenatal ultrasonography, the persistent vitelline vein should be included in the differential diagnosis to allow prompt evaluation and treatment after birth.

Closing the Gender Gap: Increased Female Authorship in AJR and Radiology.

OBJECTIVE: The purpose of this study was to evaluate gender differences in the authorship of original research articles by radiologists in two major American radiology journals, AJR and Radiology. MATERIALS AND METHODS: In a retrospective bibliometric analysis, all original articles published in AJR and Radiology during three 3-year periods (1991-1993, 2001-2003, and 2011-2013) were reviewed to determine the gender of the first and corresponding radiology authors. In addition, radiologic subspecialty and country of the authors were also abstracted from each article. RESULTS: The gender of the first and corresponding authors could be determined for 10,043 of 10,228 authors (98.2%) of original research in radiology. Between the periods 1991-1993 and 2011-2013, the percentage of female authors significantly increased: from 20.4% to 34.4%, respectively, among first authors (p < 0.0001); and from 18.0% to 28.7%, respectively, among corresponding authors (p < 0.0001). There was a significant correlation between the gender of the first and corresponding authors (p < 0.05). In the 2011-2013 period, the proportion of female authors was highest in breast (64.2%) and pediatric (48.2%) and lowest in vascular and interventional (18.5%) and cardiac (21.0%) subspecialties. The proportion of female authors was the highest in The Netherlands (47.3%), South Korea (37.9%), France (36.2%), and Italy (33.6%). CONCLUSION: There was a significant increase in the female authorship of original research articles in two major American radiology journals between the periods 1991-1993 and 2011-2013.

Domestic Violence in the Context of the COVID-19 Pandemic: A Synthesis of Systematic Reviews.

The current systematic meta-review aimed to map out, characterize, analyze, and synthesize the overarching findings of systematic reviews on domestic violence (DV) in the context of COVID-19. Specifically, a systematic meta-review was conducted with three main objectives: (1) to identify what types and aspects of DV during COVID-19 have been reviewed systematically to date (research trends), (2) to synthesize the findings from recent systematic reviews of the theoretical and empirical literature (main findings), and (3) to discuss what systematic reviewers have proposed about implications for policy and practice as well as for future primary research (implications). We identified, appraised, and synthesized the evidence contained in systematic reviews by means of a so-called systematic meta-review. In all, 15 systematic reviews were found to be eligible for inclusion in the current review. Thematic codes were applied to each finding or implication in accordance with a set of predetermined categories informed by the DV literature. The findings of this review provide clear insight into current knowledge of prevalence, incidence, and contributing factors, which could help to develop evidence-informed DV prevention and intervention strategies during COVID-19 and future extreme events. This systematic meta-review does offer a first comprehensive overview of the research landscape on this subject. It allows scholars, practitioners, and policymakers to recognize initial patterns in DV during COVID-19, identify overlooked areas that need to be investigated and understood further, and adjust research methods that will lead to more robust studies.

Comparison of angiographic change in side-branch ostium after drug-coated balloon vs. drug-eluting stent vs. medication for the treatment of de novo coronary bifurcation lesions.

OBJECTIVES: Data on side-branch (SB) ostial effect after drug-coated balloon (DCB) treatment in the context of de novo coronary bifurcation lesions are limited. We aimed to investigate the angiographic outcomes of SB ostium after DCB treatment compared with drug-eluting stents (DESs) implantation in the main vessel (MV) or optimal medical therapy (OMT) for the treatment of de novo coronary bifurcation lesions. METHODS: Serial angiographic changes in the SB ostium were compared between DCB, DES, and medication alone for MV treatment. Δ value was calculated by subtracting the follow-up value from the pre-procedure value. RESULTS: A total of 132 bifurcation lesions were included for analysis (44 lesions in DCB group; 38 lesions in DES group; 50 lesions in OMT group). The minimal lumen diameter (MLD) of SB ostium showed an increase at follow-up in the DCB group, whereas a decrease was observed in both the DES and OMT groups (ΔMLD: -0.16 ± 0.45 mm for DCB group vs. 0.50 ± 0.52 mm for DES group vs. 0.08 ± 0.38 mm for OMT group, p < 0.001). The diameter stenosis (DS) of SB ostium showed a marked decrease at follow-up in the DCB group, in contrast to an increase observed in both the DES and OMT groups (ΔDS: 8.01 ± 18.96% for DCB group vs. -18.68 ± 18.60% for DES group vs. -2.05 ± 14.58% for OMT group, p < 0.001). CONCLUSIONS: In de novo coronary bifurcation lesions, DCB treatment on the MV demonstrated favorable angiographic outcomes in the SB ostium at 6-9 month follow-up compared to DES implantation or OMT.

Impact of Drug-Coated Balloon-Based Revascularization in Patients with Chronic Total Occlusions.

Background: Percutaneous coronary intervention (PCI) with a drug-eluting stent (DES) for chronic total coronary occlusions (CTOs) improves clinical symptoms and quality of life. However, data on drug-coated balloon (DCB)-based PCI in CTO lesions are limited. Methods: A total of 200 patients were successfully treated for CTO lesions, either with DCB alone or in combination with DES (DCB-based PCI). They were compared with 661 patients who underwent second-generation DES implantation for CTO from the PTRG-DES registry (DES-only PCI). The endpoint was major adverse cardiovascular events (MACEs), which included a composite of cardiac death, myocardial infarction, stent or target lesion thrombosis, target vessel revascularization, and major bleeding at 2 years. Results: In the DCB-based PCI group, 49.0% of patients were treated with DCB only and 51.0% underwent the hybrid approach combining DCB with DES. Bailout stenting was performed in seven patients (3.5%). The DCB-based PCI group exhibited fewer stents (1.0; IQR: 0.0-1.0 and 2.0; IQR: 1.0-3.0, p < 0.001), shorter stent lengths (6.5 mm; IQR: 0.0-38.0 mm and 42.0 mm; IQR: 28.0-67.0 mm, p < 0.001), and lower usage of small stents with a diameter of 2.5 mm or less (9.8% and 36.5%, p < 0.001). Moreover, the DCB-based PCI group had a lower rate of MACEs than the DES-only PCI group (3.1% and 13.2%, p = 0.001) at 2-year follow-up. Conclusions: The DCB-based PCI approach significantly reduced the stent burden, particularly in the usage of small stent diameters, and resulted in a lower risk of MACEs compared to DES-only PCI in CTO lesions.

Sex-based outcomes on unguided de-escalation from ticagrelor to clopidogrel in stabilized patients with acute myocardial infarction undergoing percutaneous coronary intervention: a post-hoc analysis of the TALOS-AMI.

Background: The TALOS-AMI study highlighted the effectiveness of a de-escalation strategy shifting from ticagrelor to clopidogrel 1 month after percutaneous coronary intervention (PCI), resulting in significant reduction in clinical events, primarily attributed to a substantial decrease in bleeding events. Nevertheless, the impact of this strategy on outcomes based on sex remains unclear. Methods: This was a post-hoc analysis of the TALOS-AMI study. At 1 month after PCI, patients who remained adherent to aspirin and ticagrelor without experiencing major adverse events were randomized into either the de-escalation group (clopidogrel plus aspirin) or the active control group (ticagrelor plus aspirin) for an additional 12 months. The primary endpoint encompassed a composite of cardiovascular death, myocardial infarction, stroke, and Bleeding Academic Research Consortium bleeding type 2 or greater at 12 months after randomization. Results: Among the 2,697 patients included in this study, 454 (16.8%) were women. Women, characterized by older age and a higher prevalence of hypertension, diabetes, impaired renal function, and non-ST-segment myocardial infarction, exhibited a lower primary endpoint at 12 months compared to men [adjusted hazards ratio (HR), 0.60; 95% confidence interval (CI), 0.37-0.95; P = 0.03]. Compare to the active control group, the de-escalation group demonstrated a reduced risk of the primary endpoint in both women (adjusted HR, 0.38; 95% CI, 0.15-0.95; P = 0.039) and men (adjusted HR, 0.56; 95% CI, 0.40-0.79; P = 0.001) (interaction P = 0.46). Conclusions: In stabilized patients post-PCI with drug-eluting stents for acute myocardial infarction, the primary endpoint was lower among women compared to men. In this cohort, the benefits of an unguided de-escalation strategy from ticagrelor to clopidogrel were comparable in women and men.

Ecological System Levels of Risk Factors for Intimate Partner Homicide Perpetration and Victimization: A Three-Level Meta-analysis.

This study aims to identify, through an advanced three-level meta-analytic approach, the predictive validity of the different ecological systems for IPH perpetration and victimization relative to IPV, other homicides, IPH followed by suicide, and non-abused control groups. Twenty-nine studies were included, with 473 effect sizes in a unique population of 16,237. Each factor was classified into one of three ecological systems: ontogenetic, microsystem, and exosystem. The results revealed that the impact of each ecological system on the likelihood of IPH varies depending on the offender/victim gender and the comparison groups. Specifically, the largest odds ratios for intimate partner femicide (IPF) perpetration/victimization versus IPV were found at the microsystem level as well as IPF victimization versus non-abused group at the ontogenetic level of risk factors. Moderator analyses showed that the difference between male IPH and IPV perpetrators in the effect of the microsystem level of risk factors is explained in part by a set of cultural values and beliefs toward equality. We then discuss the present results' implications for risk assessment and the prevention/treatment of IPH perpetration and victimization, as well as future research.

Domestic Homicide: A Synthesis of Systematic Review Evidence.

Domestic homicide (DH) is the most extreme form of domestic violence (DV). There has been a growing worldwide interest in DH offenses and the characteristics of perpetrators and victims, and it is evidenced in part by the increase in the number of primary research studies in this area. The findings of a large number of the available primary literature have already been summarized into several systematic reviews. The principal purposes of this study were to identify what types and aspects of DH have been reviewed systematically (research trends), to synthesize findings from recent systematic reviews of the theoretical and empirical literature on the different types of DH (main findings), and to consider what existing reviews can tell us about the implications for policy and practice as well as future primary research (implications). The current study utilized a systematic review approach to locate systematic reviews of studies on DH. The final sample included 25 systematic review articles published from 2010 to 2020, including 12 on intimate partner homicide, eight on child homicide, and five on familicide. The main research questions varied across systematic reviews, but they included risk factors, statistics on incidence and prevalence, theories, risk assessment tools, punishment and disposition, and prevention strategies. Building on the synthesis findings, the current study concludes with suggestions for future systematic review research and implications for practice and policy efforts.

Screening of novel peptides that specifically interact with vitamin D bound biocomplex proteins.

The majority of the vitamin D that is present in the blood binds to vitamin D binding protein (VDBP) and circulates in the form of a complex (VDBP-Complex). Knowing the level of vitamin D in the body is crucial for vitamin D-related treatments so that the right dosage of vitamin D can be given. In other words, it is essential to distinguish between the protein VDBP and the complex form bound to vitamin D. As a novel way for the detection of VDBP-Complex, a more effective phage display methodology was applied in this study along with the addition of two approaches. In order to screen a sequence specific to the target only, the pre-binding method and after-binding method were performed. VDBP-Complex was directly coated on the petri dishes. In order to select phages that specifically bind to the VDBP-Complex, random phages were attached, and selected by 7 times of biopanning. Individual DNA sequences were analyzed for each biopanning to find specific peptide sequences for VDBP-Complex. The affinity of binding phages was verified by ELISA assay using an anti-M13 antibody. The phage having a sequence of SFTKTSTFTWRD (called as M3) has shown the highest binding affinity to VDBP-Complex. As a result of the removal test of VDBP-Complex using magnetic beads conjugated with M3 peptide, it was confirmed that significant decrease of VDBP-Complex. The unique characteristic of the M3 sequence was confirmed through a sequence-modified peptide (SFT motif). That is, it is expected that the M3 peptide may be used to determine the vitamin D levels in the blood.

Long-Term Clinical Outcomes of Drug-Coated Balloon Treatment for De Novo Coronary Lesions.

PURPOSE: Data are limited on the long-term efficacy and safety of drug-coated balloon (DCB) treatment in comparison to drug-eluting stent (DES) for de novo coronary lesions. We investigated the long-term clinical outcomes of DCB treatment in percutaneous coronary intervention (PCI) for de novo coronary lesions. MATERIALS AND METHODS: A total of 103 patients scheduled for elective PCI for de novo non-small coronary lesions (≥2.5 mm) who were successfully treated with DCB alone were retrospectively compared with 103 propensity-matched patients treated with second-generation DES from the PTRG-DES registry (n=13160). All patients were followed for 5 years. The primary endpoint was major adverse cardiac events [MACE; cardiac death, myocardial infarction, stroke, target lesion thrombosis, target vessel revascularization (TVR), and major bleeding] at 5 years. RESULTS: At 5-year clinical follow-up, Kaplan-Meier estimates of the rate of MACE were significantly lower in the DCB group [2.9% vs. 10.7%; hazard ratio (HR): 0.26; 95% confidence interval (CI): 0.07-0.96; log-rank p=0.027]. There was a significantly lower incidence of TVR in the DCB group (1.0% vs. 7.8%; HR: 0.12; 95% CI: 0.01-0.98; long-rank p=0.015), and there was major bleeding only in the DES group (0.0% vs. 1.9%; log-rank p=0.156). CONCLUSION: At 5-year follow-up, DCB treatment was significantly associated with reduced incidences of MACE and TVR, compared with DES implantation, for de novo coronary lesions.

Impact of Scoring Balloon Angioplasty on Lesion Preparation for DCB Treatment of Coronary Lesions.

OBJECTIVE: The aim of this study was to evaluate the efficacy of scoring balloon angioplasty for drug-coated balloon (DCB) treatment in percutaneous coronary intervention. BACKGROUND: The scoring balloon angioplasty may play a pivotal role in enhancing the outcomes of DCB treatment. METHODS: A total of 259 patients (278 lesions) with coronary artery disease successfully treated with DCB were retrospectively enrolled. The mean age of the patients was 62.2 ± 11.1 years, and the majority of patients were men (68.7%). The study's endpoint was defined as achieving an optimal angiographic result, which consisted of Thrombolysis in Myocardial Infarction (TIMI) flow grade 3, residual diameter stenosis ≤ 30%, and dissection less than type C after the procedure. RESULTS: Angioplasty was performed for 61 lesions with a scoring balloon and 217 lesions with a non-scoring balloon. All lesions were TIMI flow grade 3 except two lesions in the non-scoring balloon group. The scoring balloon group had a higher prevalence of residual diameter stenosis ≤ 30% (68.9% vs. 39.6%, p < 0.001), while severe dissection, defined as type C or greater, was observed less frequently (9.8% vs. 31.8%, p = 0.001). Moreover, the scoring balloon group achieved a superior rate of optimal angiographic results (60.7% vs. 28.6%, p < 0.001). In multivariable analysis, scoring balloon (OR: 3.08 [95% confidence interval, 1.47-6.58], p = 0.003) and DCB balloon-to-artery ratios (OR: 5.46 [95% confidence interval, 1.43-21.93], p = 0.014) were independent factors in the increasing rate of optimal angiographic result. CONCLUSIONS: The application of a scoring balloon catheter for lesion preparation, aiming to make them suitable for DCB treatment, was associated with a decreased risk of severe dissection and a greater occurrence of optimal angiographic outcomes compared with non-scoring balloon angioplasty.

Clinical Impact of Drug-Coated Balloon-Based Percutaneous Coronary Intervention in Patients With Multivessel Coronary Artery Disease.

BACKGROUND: Data on drug-coated balloon (DCB) treatment in the context of multivessel coronary artery disease (CAD) are limited. OBJECTIVES: The purpose of this study was to investigate the impact of DCB-based treatment on percutaneous coronary intervention for multivessel CAD. METHODS: A total of 254 patients with multivessel disease successfully treated with DCBs or in combination with drug-eluting stents (DES) were retrospectively enrolled (DCB-based group) and compared with 254 propensity-matched patients treated with second-generation DES from the PTRG-DES (Platelet Function and Genotype-Related Long-Term Prognosis in Drug-Eluting Stent-Treated Patients With Coronary Artery Disease) registry (n = 13,160) (DES-only group). Major adverse cardiovascular events (MACE) comprised cardiac death, myocardial infarction, stroke, stent thrombosis, target vessel revascularization, and major bleeding at 2 years. RESULTS: Baseline clinical characteristics were comparable between the groups. In the DCB-based group, 34.3% of patients were treated with DCBs only and 65.7% were treated with the DES hybrid approach. The number of stents and total stent length were significantly reduced by 65.4% and 63.7%, respectively, in the DCB-based group compared with the DES-only group. Moreover, the DCB-based group had a lower rate of MACE than the DES-only group (3.9% and 11.0%; P = 0.002) at 2-year follow-up. The DES-only group had a higher risk for cardiac death and major bleeding. CONCLUSIONS: The DCB-based treatment approach showed a significantly reduced stent burden for multivessel percutaneous coronary intervention and led to a lower rate of MACE than the DES-only treatment. This study shows that DCB-based treatment approach safely reduces stent burden in multivessel CAD, and improved long-term outcomes may be expected by reducing stent-related events.
