Background/aim: Pre-mRNA processing factor 4 (PRPF4), a core protein of U4/U6 small nuclear ribonucleoproteins (snRNPs), is crucial for maintaining their structure by interacting with PRPF3 and Cyclophilin H. Beyond its role in splicing, PRPF4 has been implicated in cell survival, apoptosis, and oncogenesis. Although PRPF4 mutations have been associated with retinitis pigmentosa, its role in glioblastoma (GBM) remains unclear. This study aimed to investigate the function of PRPF4 in GBM progression and its potential as a therapeutic target., Materials and Methods: Gene expression profiling was conducted to compare PRPF4 levels between GBM tumors and normal tissues. PRPF4 expression was also evaluated in various cancer and GBM cell lines. Stable PRPF4 knockdown cell lines were established using A172 and T98G GBM cell lines. Cellular proliferation, apoptosis, migration, and invasion were assessed through gene expression and functional assays. Additionally, molecular pathways affected by PRPF4 knockdown were examined, focusing on the p38 MAPK signaling pathway. Finally, metabolic processes in PRPF4 knockdown cells were estimated through proteomic analysis., Results: PRPF4 expression was elevated in GBM. Knockdown of PRPF4 reduced cell proliferation, induced apoptosis, and suppressed migration and invasion in GBM cells. PRPF4 knockdown also suppressed MKK3/6-p38-ATF2 and RAS-MEK-ERK1/2 signaling pathways. Proteome analysis revealed disruptions in metabolic pathways, including glutathione and carbon metabolisms, which are associated with GBM progression., Conclusion: PRPF4 knockdown inhibits GBM progression by reducing p38 MAPK and ERK signaling cascade with metabolic alterations. Targeting PRPF4 may offer novel therapeutic strategies for GBM treatment., (Copyright © 2025 International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

LGBTQ+ individuals face discrimination in healthcare settings. Magnet hospitals have been associated with positive patient outcomes, yet it remains uncertain whether Magnet designation is associated with hospitals' LGBTQ+ inclusivity in policies and practices. This study examined 801 American hospitals across 47 states that participated in the Healthcare Equality Index (HEI) in 2021. Multilevel modeling was utilized to investigate the association between Magnet status and HEI scores, adjusting for hospital type and state-level covariates, including LGBTQ+ inclusiveness in laws, political climate, racial/ethnic minority population, and Medicaid expansion status. Among the 801 hospitals, 32.1% (257 hospitals) held Magnet status. Magnet hospitals demonstrated higher HEI scores compared to non-Magnet hospitals (γ = 2.13, p = 0.022), despite significant variations across states (intraclass correlation = 0.22). No significant cross-level interactions were found. Overall, Magnet designation is independently associated with improved LGBTQ+ inclusivity in hospitals regardless of the state in which the hospital is located. Policymakers and healthcare leaders should consider leveraging the Magnet Recognition Program as a benchmark for promoting LGBTQ+ inclusivity within hospitals. Additionally, all healthcare institutions should prioritize comprehensive evaluations and improvements to their policies and practices to ensure inclusivity for LGBTQ+ patients., (© 2024 The Author(s).

Background: Mesenchymal stem cells (MSCs) are promising candidates for regenerative therapy due to their self-renewal capability, multilineage differentiation potential, and immunomodulatory effects. The molecular characteristics of MSCs are influenced by their location. Recently, epidural fat (EF) and EF-derived MSCs (EF-MSCs) have garnered attention due to their potential benefits to the spinal microenvironment and their high expression of neural SC markers. However, their clinical applications are limited due to cell senescence and limited accessibility of EF. Although many studies have attempted to establish an immortalized, stable SC line, the characteristics of immortalized EF-MSCs remain to be clarified., Aim: To establish and analyze stable immortalized EF-MSCs., Methods: The phenotypes of EF-MSCs were analyzed using optical microscopy. Cell immortalization was performed using lentiviral vectors. The biomolecular characteristics of the cells were analyzed by immunoblotting, quantitative PCR, and proteomics., Results: The immortalized EF-MSCs demonstrated a significantly extended lifespan compared to the control group, with well-preserved adipogenic potential and SC surface marker expression. Introduction of human telomerase reverse transcriptase genes markedly increased the lifespan of EF-MSCs. Proteomics analysis revealed substantial increase in the expression of DNA replication pathway components in immortalized EF-MSCs., Conclusion: Immortalized EF-MSCs exhibited significantly enhanced proliferative capacity, retained adipogenic potential, and upregulated the expression of DNA replication pathway components., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest to declare., (©The Author(s) 2025.

Background: The COVID-19 pandemic has had profound psychophysiological and socioeconomic effects worldwide. COVID-19 anxiety syndrome (CAS) is a specific cluster of maladaptive coping strategies, including perseveration and avoidance behaviours, in response to the perceived threat and fear of COVID-19. CAS is distinct from general COVID-19 anxiety. The level of CAS in the postpandemic era remained unknown. Despite extensive research on general COVID-19 anxiety and COVID-19 vaccine hesitancy (CVH), few studies have investigated the association between CAS and CVH. The present study aimed to assess the level of CAS and the prevalence of CVH and explore the association between CAS and CVH in the general population of Hong Kong., Methods: This cross-sectional study was conducted in Hong Kong. Participants were recruited using convenience and snowball sampling methods and completed an online or a paper-based questionnaire comprising two well-validated instruments. The COVID-19 Anxiety Syndrome Scale (C-19ASS), which includes the C-19ASS-P and C-19ASS-A subscales, was used to evaluate CAS in terms of perseveration and avoidance behaviours. The COVID-19 Vaccine Hesitancy Scale (CVHS) was used to determine the presence of CVH., Results: This study included 389 participants. The median C-19ASS-P and C-19ASS-A scores were 8 (Interquartile range (IQR) 5-13) and 3 (IQR 0-6), respectively. The CVHS scores revealed a CVH prevalence of 68.1%. A significantly larger proportion of participants with CVH rated "hesitant" compared with those without CVH across all the CVHS items. Furthermore, the median C-19ASS-P and C-19ASS-A scores were significantly higher for participants without CVH than for those with CVH., Conclusions: Our findings revealed that CAS persists and CVH is common in the postpandemic era and that CAS is associated with CVH. Comprehensive interventions addressing both informational and psychological aspects are needed to increase the rate of vaccine acceptance and to mitigate the effect of CAS on public health outcomes., Competing Interests: Declarations. Ethics approval and consent to participate: The present study was approved by the Research Ethics Committee of the School of Nursing and Health Studies at Hong Kong Metropolitan University. The participants were informed about the study objectives before giving written consent. The procedures followed the ethical principles of the Declaration of Helsinki.

Objective: The leptomeningeal ivy sign is a distinctive finding of moyamoya disease (MMD), characterized by a linear high signal intensity along the cortical sulci on contrast-enhanced T1 magnetic resonance imaging (MRI) and fluid-attenuated inversion-recovery MRI. We recently identified a similar linear enhancement along the cortical sulci using gadolinium-enhanced vessel wall MRI (VWMR) in patients with MMD. The aim of this study was to introduce the concept of the "VWMR ivy sign (VIS)"., Methods: Eighteen MMD patients underwent gadolinium-enhanced VWMR. We identified the VIS in gadolinium-enhanced VWMR, represented by a linear high intensity along the cortical sulci. The VIS was assessed by comparing pre and postcontrast T1 black blood sequences on VWMR and was investigated in the precentral, central, and postcentral sulci. "VIS scores" were calculated by the sum of VIS in the three sulci, ranged from 0 to 3. We compared the VIS scores according to different stroke presentations (non-stroke, ischemic stroke, and hemorrhagic stroke). The inter-modality agreement for identifying VIS and fluid-attenuated inversion-recovery (FLAIR)/cortical sulci on contrast-enhanced T1 MRI (CEMR) ivy sign was determined using Cohen's kappa statistics., Results: The VIS scores were significantly different among the three groups (P = 0.004). The VIS scores in both the ischemic and hemorrhagic groups were significantly higher than those in the non-stroke group (ischemic vs. non-stroke, P = 0.009; hemorrhagic vs. non-stroke, P = 0.004). After adjusting for age and sex using the non-stroke group as a reference group, the VIS scores were significantly higher in the ischemic and hemorrhagic groups (P=0.046, OR 8.27, 95% CI 1.03-66.19 and P=0.039, OR 7.78, 95% CI 1.11-54.48, respectively). Inter-modality agreement between VIS and FLAIR ivy sign was substantial, perfect, and substantial in the precentral, central, and postcentral sulci, respectively (precentral sulcus, κ=0.609, 95% CI=0.213-1; central sulcus, κ=1; and postcentral sulcus, κ=0.769, 95% CI=0.475-1). Inter-modality agreement between the VIS and CEMR ivy sign was substantial in the precentral, central, and postcentral sulci, respectively (precentral sulcus, κ=0.727, 95% CI=0.384-1; central sulcus, κ=0.609, 95% CI=0.384-1; and postcentral sulcus, κ=0.649, 95% CI=0.310-0.998)., Conclusion: This preliminary series introduces the concept of VIS, possibly indicating slow and retrograde flow of sulcal vessels via leptomeningeal collaterals. Future studies are needed to develop an optimal scoring system for VIS and establish its clinical correlation with stroke presentations in MMD patients.

Background: While the significance of care navigation in facilitating access to health care within the lesbian, gay, bisexual, transgender, queer, and other (LGBTQ+) communities has been acknowledged, there is limited research examining how care navigation influences an individual's ability to understand and access the care they need in real-world settings. By analyzing private sector data, we can bridge the gap between theoretical research findings and practical applications, ultimately informing both business strategies and public policy with evidence grounded in real-world efficacy., Objective: The objective of this study was to evaluate the impact of specialized virtual care navigation services on LGBTQ+ individuals' ability to comprehend and access necessary care within a national cohort of commercially insured members., Methods: This case study is based on the experience of commercially insured members, aged 18 or older, who used the LGBTQ+ Health Care Navigation (LGBTQ+ Navigation) service by Included Health between January 26 and July 31, 2023. Care coordinators assisted members by connecting them with vetted identity-affirming in-network providers, helping them navigate and understand their LGBTQ+ health benefits, and providing education and advocacy for clinical and nonclinical needs. We examined the impact of navigation on 5 member-reported outcomes. In addition to reporting the proportion who agreed or strongly agreed, we calculated an impact score that averaged assigned numerical values to all 5 question responses (1=strongly disagree to 5=strongly agree) for each respondent. We used ANOVA with Tukey post hoc tests and t tests to explore the relationships between the impact score and member characteristics, including optional self-reported demographics., Results: Out of 4703 LGBTQ+ Navigation cases, 7.53% (n=354) had member-reported outcomes. A large majority of LGBTQ+ members agreed or strongly agreed that care navigation resulted in less stress (315/354, 89%), less care avoidance (305/354, 86.2%), higher confidence in finding an identity-affirming provider (327/354, 92.4%), improved ability to comprehend health care information (312/354, 88.1%), and improved ability to engage with providers (308/354, 87%). The average impact score was 4.44 (SD 0.69), with statistically significant differences by gender identity (P=.003), race (P=.01), ethnicity (P=.008), and pronouns (P=.02). The scores were highest for members with multiple gender identities (mean 4.56, SD 0.37), and members who did not provide their race, ethnicity, or their pronouns (mean 4.55, SD 0.64). Impact scores were lowest for transgender members (mean 4.11, SD 0.95)., Conclusions: The LGBTQ+ Navigation service, by enhancing members' comprehension and use of necessary care, demonstrates potential public health utility and value. Continuous evaluation of navigation services can serve as a supplementary tool for employers seeking to promote health equity and improve belonging among employees. This is particularly important as discrimination and stigma against LGBTQ+ communities persist in the United States. Therefore, scalable and system-level changes that use navigation services are essential to reach a larger proportion of the LGBTQ+ population., (© Seul Ki Choi, Jaclyn Marshall, Patrina Sexton Topper, Andrew Pregnall, José Bauermeister.

There is evidence that BRCA1, particularly cytoplasmic BRCA1, plays a significant role in initiating apoptosis through various mechanisms. Maintaining the stability of BRCA1 in cancer cells may be a promising therapeutic strategy for breast cancer, especially in cases of triple-negative breast cancer (TNBC) lacking appropriate therapeutic targets. Previously, it was reported that cathepsin S (CTSS) interacts with the BRCT domain of BRCA1, leading to ubiquitin-mediated degradation. We further investigated the critical role of BRCA1 phosphorylation at Ser1387, which is mediated by ionizing radiation (IR)-induced activation of ATM. This phosphorylation event was identified as a key factor in CTSS-mediated ubiquitin degradation of BRCA1. The functional inhibition of CTSS, using small molecules or a knockdown system, sensitized TNBC cells when exposed to IR by restoring the stability of cytoplasmic BRCA1. The increase in cytoplasmic BRCA1 led to the degradation of anti-apoptotic BCL2, which was responsible for the radiosensitization effect observed with CTSS inhibition. These results suggest that inhibiting CTSS may be an effective strategy for radiosensitization in TNBC cells through BCL2 degradation that is mediated by inhibition of CTSS-induced BRCA1 degradation., 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.

Latinos in the United States are disproportionately affected by HIV and experience sub-optimal levels of viral suppression. Enlaces Por La Salud is an individual-level intervention implemented by personal health navigators and guided by the transnational framework to improve HIV care outcomes among newly diagnosed and out-of-care Mexican and Mexican American men and transgender women in North Carolina. The purpose of this study was to assess: (1) changes in HIV care and treatment outcomes among Enlaces participants and (2) intervention engagement and experiences. Ninety-one participants were recruited between October 2014 and August 2017 for a single-arm, mixed-methods design including surveys at baseline, 6 and 12 months and qualitative in-depth interviews immediately following the intervention with an embedded cohort (n = 19). Mean participant age was 36.8 years and most identified as cisgender male (90%). Participants were significantly more likely to have an undetectable viral load at baseline (18%) compared to 6-months (78%) (p < .001). Outcomes were sustained but not significantly increased from 6 to 12 months. Intervention engagement was high with 81% completing all six intervention sessions. In qualitative interviews, participants emphasized the importance of their relationship with the personal health navigators, who provided information, instrumental, and emotional support. A person-centered intervention guided by the lived experience of migration could be an effective way to support Latinos with HIV from diverse countries of origin to achieve viral suppression and improve overall wellbeing., Competing Interests: Declarations.

We report the first evidence for the h&#95;{b}(2P)→ϒ(1S)η transition with a significance of 3.5 standard deviations. The decay branching fraction is measured to be B[h&#95;{b}(2P)→ϒ(1S)η]=(7.1&#95;{-3.2}^{+3.7}±0.8)×10^{-3}, which is noticeably smaller than expected. We also set upper limits on π^{0} transitions of B[h&#95;{b}(2P)→ϒ(1S)π^{0}]<1.8×10^{-3}, and B[h&#95;{b}(1P)→ϒ(1S)π^{0}]<1.8×10^{-3}, at the 90% confidence level. These results are obtained with a 131.4  fb^{-1} data sample collected near the ϒ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider.

Using the e^{+}e^{-} collision data collected with the BESIII detector operating at the BEPCII collider, at center-of-mass energies from the threshold to 4.95 GeV, we present precise measurements of the cross section for the process e^{+}e^{-}→D&#95;{s}^{+}D&#95;{s}^{-} using a single-tag method. The resulting cross section line shape exhibits several new structures, thereby offering an input for a future coupled-channel analysis and model tests, which are critical to understand vector charmonium-like states with masses between 4 and 5 GeV.

Emerging SARS-CoV-2 sublineages continue to cause serious COVID-19 disease, but most individuals have not received any COVID-19 vaccine for >1 year. Assessment of long-term effectiveness of bivalent COVID-19 vaccines against circulating sublineages is important to inform the potential need for vaccination with updated vaccines. In this test-negative study at Kaiser Permanente Southern California, sequencing-confirmed BA.4/BA.5- or XBB-related SARS-CoV-2-positive cases (September 1, 2022 to June 30, 2023), were matched 1:3 to SARS-CoV-2-negative controls. We assessed mRNA-1273 bivalent relative (rVE) and absolute vaccine effectiveness (VE) compared to ≥2 or 0 doses of original monovalent vaccine, respectively. The rVE analysis included 20,966 cases and 62,898 controls. rVE (95%CI) against BA.4/BA.5 at 14-60 days and 121-180 days was 52.7% (46.9-57.8%) and 35.5% (-2.8-59.5%) for infection, and 59.3% (49.7-67.0%) and 33.2% (-28.2-68.0%) for Emergency Department/Urgent Care (ED/UC) encounters. For BA.4/BA.5-related hospitalizations, rVE was 71.3% (44.9-85.1%) and 52.0% (-1.2-77.3%) at 14-60 days and 61-120 days, respectively. rVE against XBB at 14-60 days and 121-180 days was 48.8% (33.4-60.7%) and -3.9% (-18.1-11.3%) for infection, 70.7% (52.4-82.0%) and 15.7% (-6.0-33.2%) for ED/UC encounters, and 87.9% (43.8-97.4%) and 57.1% (17.0-77.8%) for hospitalization. VE and subgroup analyses (age, immunocompromised status, previous SARS-CoV-2 infection) results were similar to rVE analyses. rVE of mRNA-1273 bivalent vaccine against BA.4/BA.5 and XBB infections, ED/UC encounters, and hospitalizations waned over time. Periodic revaccination with vaccines targeting emerging variants may be important in reducing COVID-19 morbidity and mortality.

Background/Objectives: Radiofrequency ablation (RFA) is an important local treatment for hepatocellular carcinoma (HCC). This study aimed to evaluate the characteristics of tumor recurrence after RFA and analyze predictors of tumor recurrence and survival in patients with HCC. Methods: We retrospectively reviewed data from treatment-naïve patients with HCC who underwent RFA for HCC treatment between 2008 and 2017 at four tertiary hospitals in South Korea. Results: A total of 636 patients with HCC treated with RFA were enrolled in the study. The mean age was 66.3 ± 10.4 years, with 75.0% of patients being male. Most patients (96.7%) had underlying liver cirrhosis, and viral hepatitis (types B and C) accounted for most cases. The average maximum tumor size was 2.2 ± 0.9 cm, with 84.3% of tumors being single lesions. During the follow-up period, 331 patients experienced recurrence, with 95.5% of cases being intrahepatic and one-fifth occurring at the RFA site. Most patients underwent RFA or transarterial chemoembolization as subsequent therapy for recurrence. Multivariate analysis revealed that age, the albumin-bilirubin (ALBI) grade, and Child-Pugh class B status were independent factors associated with tumor recurrence. Only the ALBI grade was significantly associated with mortality. Additionally, the ALBI grade differentiated between recurrence-free survival and overall survival in the Kaplan-Meier survival curve. Conclusions: The ALBI grade was independently associated with tumor recurrence and prognosis in patients with HCC following RFA. This grading system can help clinicians identify high-risk patients, optimize treatment strategies, and enhance patient care.

We report the precise measurements of the cross section of e^{+}e^{-}→hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study of the cross sections and find a complex system composed of three resonances of R(3760), R(3780), and R(3810). For the first time, we measure the R(3810) electronic width to be (19.4±7.4±12.1)  eV. For the R(3760) resonance, we measure the mass to be (3751.9±3.8±2.8)  MeV/c^{2}, the total width to be (32.8±5.8±8.7)  MeV, and the electronic width to be (184±75±86)  eV. For the R(3780) resonance, we measure its mass to be (3778.7±0.5±0.3)  MeV/c^{2}, total width to be (20.3±0.8±1.7)  MeV, and electronic width to be (265±67±83)  eV. Forty-seven years ago, the ψ(3770) resonance was discovered, and was subsequently interpreted as the 1^{3}D&#95;{1}-wave dominant state of charmonium. However, our analysis of the total-hadron cross sections indicates that the ψ(3770) is not a single state, but a complex system composed of the R(3760), R(3780), and R(3810) resonances. Among these, we interpret the R(3780) is a resonance dominated by the 1^{3}D&#95;{1} charmonium state.

Background: The aim of this study was to disseminate information about the safety of bivalent coronavirus disease 2019 (COVID-19) mRNA booster vaccines administered to adults in the Republic of Korea., Methods: Two databases were used to assess the safety of COVID-19 booster doses of Pfizer BA.1, Pfizer BA.4/5, Moderna BA.1, and Moderna BA.4/5 vaccines for adults aged 18 years and older. Adverse events (AEs) were analyzed using data reported to the web-based COVID-19 vaccination management system (CVMS) and a self-reported text-message survey., Results: Between October 11, 2022 and March 30, 2023, the CVMS received reports of 2,369 (93.7%) non-serious AEs from vaccinated adults, along with 158 (6.3%) serious AEs, which included 5 cases of anaphylaxis and 33 deaths. From October 11, 2022 to January 27, 2023, 40,022 people aged 18 and older responded to a survey conducted via text message. The booster doses were associated with fewer local and systemic AEs compared to the original vaccines. After receiving the bivalent vaccine, the most commonly reported AEs were pain at the injection site, headache, fatigue, and myalgia., Conclusion: Overall, bivalent vaccines exhibited fewer AEs compared to the original vaccines. The majority of AEs were non-serious, and serious AEs were rare among adults aged 18 years and older following vaccination with the Pfizer and Moderna bivalent vaccines.

This study compared glycosylated hemoglobin (HbA1c) levels in the first and second trimesters of pregnancy and assessed maternal and neonatal outcomes according to HbA1c variations among women with pregestational diabetes. This retrospective, multicenter Korean study involved mothers with diabetes who had given birth in 17 hospitals. A total of 292 women were divided into three groups based on HbA1c levels during the first and second trimesters: women with HbA1c levels maintained at <6.5% (well-controlled [WC] group); women with HbA1c ≥ 6.5% (poorly-controlled [PC] group); and women with HbA1c ≥ 6.5% in the first trimester but <6.5% in the second trimester (improved-control [IC] group). The PC group had the highest pregnancy-associated hypertension (PAH) incidence, while the incidence did not significantly differ between the WC and IC groups. The receiver operating characteristic (ROC) curve indicated that HbA1c in the second trimester could predict PAH with a cut-off value of 5.7%. The PC versus WC versus IC group showed statistically significantly higher neonatal birthweight and significantly higher rates of large for gestational age (LGA); however, those were not significantly different between the WC and IC groups. HbA1c levels in the second trimester could predict LGA, with a cut-off value of 5.4%. Therefore, the second trimester HbA1c levels were significantly associated with both maternal and neonatal outcomes.

Background/objectives: Perceived diet quality (PDQ) has been suggested as an easy-to-use dietary assessment tool. However, its practicality and efficiency are still questionable. This study aimed to gauge the utility of PDQ as an alternative dietary assessment tool among Korean adults by examining PDQ and its associated factors., Subjects/methods: An online survey was conducted on 514 Korean adults aged 19 to 64 years in October 2022. PDQ was assessed using a 5-point Likert scale, and participants were categorized into healthy, fair, or unhealthy PDQ groups. The participants were asked about the perceived importance of nutrients and food groups for health and the extent to which they considered these factors in their usual diets using a 5-point Likert scale. A multivariate linear regression model was used to identify the factors associated with PDQ., Results: About 26.7% of participants rated their diets as healthy, while 63.2% rated them as fair and 10.1% rated them as unhealthy. Participants with a healthy PDQ rated perceived importance and consideration of nutrients and food groups higher than the fair or unhealthy PDQ groups. A healthier PDQ was associated with the male gender, an older age, being normal or underweight, having better subjective health, lower use of alcohol, being physically active, having a high interest in healthy diets, and a higher perception of the importance of nutrients and food groups for health., Conclusion: The PDQ could serve as a simple and rapid screening tool for identifying individuals at risk of poor diets., Competing Interests: Conflict of Interest: The authors declare no potential conflicts of interests., (©2024 The Korean Nutrition Society and the Korean Society of Community Nutrition.)

The incidence of melanoma, a highly aggressive skin cancer, continues to increase worldwide, particularly among populations with lighter skin tones. The diagnostic challenge of melanoma lies in the absence of a distinctive clinical presentation, as its characteristics vary based on anatomical location, growth type, and histopathology. The melanoma-associated antigen (MAGE) gene family is differentially expressed in various human cancers, including melanoma. In this study, we explored the association between human MAGEA2 (hMAGEA2) expression and melanoma. Using a human melanoma tissue array, we confirmed that hMAGEA2 expression was higher in melanoma and metastatic melanoma than in normal tissues. Additionally, we used SK-MEL-5 and SK-MEL-28 cell lines to investigate the cellular and molecular mechanisms underlying melanoma progression and invasiveness. In SK-MEL-5 and SK-MEL-28 cells, hMAGEA2 overexpression accelerated cell proliferation. Conversely, the knockdown of hMAEGA2 reduced cell proliferation, colony formation, and migration significantly and induced arrest at the G2/M phase of the cell cycle. With respect to the molecular mechanism, the knockdown of hMAGEA2 decreased the phosphorylation of Akt, JNK, and p38 MAPK. Additionally, hMAGEA2 knockdown reduced tumor formation significantly at the in vivo level. Collectively, the robust correlation between hMAGEA2 and melanoma metastasis supports the potential utility of hMAGEA2 as both a diagnostic marker and novel therapeutic target for patients with melanoma metastasis.

Introduction: Suicide is a major social issue in Korea. Suicide attempt or self-harm (SA/SH)-a risk factor for suicides-is in itself a major public health problem. Investigating vulnerable populations is the first step for designing an effective prevention program. This study aimed to investigate the epidemiology and outcomes of patients with severe injuries related to suicide attempts or self-harm (SA/SH) by age groups, using a nationwide database., Materials and Methods: This retrospective observational study was conducted in Korea between 2016 and 2020. Its participants were patients with severe injuries, who were treated by emergency medical service (EMS). From among injured patients who met the criteria for a field-based injury triage scheme or had a prehospital physiological abnormality, those with SA/SH were included. Exposure was based on age groups: adolescents (10-18 years), adults (19-64 years), and older adults (≥65 years). The study's outcomes were in-hospital mortality. Patients' characteristics and outcomes were compared by age groups and SA/SH mechanisms. Predictors of mortality were investigated using multivariable logistic regression analysis., Results: Among the 204,211 patients with severe injuries transferred by EMS, 43,945 (21.5 %) were SA/SH-related. Their median (interquartile) age was 48 (35-61) years, and 52.9 % were female patients. The common SA/SH mechanisms were: poisoning (67.6 %), hanging (16.3 %), and jumping (8.1 %). Overall, the mortality was 21.9 %, but it was higher for hanging (69.2 %) and jumping (62.0 %), than for common poisoning (6.5 %). Among adolescents, poisoning (46.1 %), followed by jumping (34.0 %) was common, and the mortality was 23.3 %. In the older adults, poisoning (68.6 %), followed by hanging (20.2 %) was common, and the mortality was 34.9 %. Older adults compared to adults, males compared to females, and hanging and jumping compared to poisoning, were associated with higher mortality., Conclusions: More than 20 % of EMS treated patients with severe injury were SA/SH-related, and the mortality was over 20 %. Although poisoning was the most common mechanism, the high proportions of jumping and hanging with high mortality, resulted in adolescents and the older adults groups having high mortality. Therefore, designing target-specific SA/SH prevention programs based on age, sex, and common SA/SH mechanisms are necessary., Competing Interests: Declaration of competing interest All authors have no other relationships/conditions/circumstances that present potential conflict of interest., (Copyright © 2024 Elsevier Ltd.

Background: This study aimed to develop a clinical model to predict late-onset fetal growth restriction (FGR)., Methods: This retrospective study included seven hospitals and was conducted between January 2009 and December 2020. Two sets of variables from the first trimester until 13 weeks (E1) and the early third trimester until 28 weeks (T1) were used to develop the FGR prediction models using a machine learning algorithm. The dataset was randomly divided into training and test sets (7:3 ratio). A simplified prediction model using variables with XGBoost's embedded feature selection was developed and validated., Results: Precisely 32,301 patients met the eligibility criteria. In the prediction model for the whole cohort, the area under the curve (AUC) was 0.73 at E1 and 0.78 at T1 and the area under the precision-recall curve (AUPR) was 0.23 at E1 and 0.31 at T1 in the training set, while an AUC of 0.62 at E1 and 0.73 at T1 and an AUPR if 0.13 at E1, and 0.24 at T1 were obtained in the test set. The simplified prediction model performed similarly to the original model., Conclusions: A simplified machine learning model for predicting late FGR may be useful for evaluating individual risks in the early third trimester., Competing Interests: The authors declare no conflicts of interest.

As electronic circuit integration intensifies, there is a rising demand for dielectric insulators that provide both superior insulation and high dielectric constants. This study focuses on developing high-k dielectric insulators by controlling the phase of the Hf 0.5 Zr 0.5 O 2 (HZO) film with additional doping, utilizing yttrium (Y), tantalum (Ta), gallium (Ga), silicon (Si), and aluminum (Al) as dopants. Doping changes the ratio of tetragonal to monoclinic phases in doped HZO films, and Y-doped HZO (Y:HZO) films specifically exhibit a high tetragonal phase ratio and a dielectric constant of 40.9, indicating superior insulating properties compared to undoped HZO films. To clarify the fundamental mechanism driving the enhancement in dielectric properties, we have carried out various analyses combined with density functional theory (DFT) calculations. Through the optimization of the post-deposition annealing (PDA) process and the heterojunction structure with Al 2 O 3 , an Al 2 O 3 /Y:HZO heterojunction with a high dielectric constant and even lower leakage current compared to a single layer was developed. The thin-film transistor (TFT) with the Au/Ti/amorphous InGaZnO 4 (a-IGZO)/Al 2 O 3 /YHZO/TiN heterojunction structure exhibits low subthreshold swing (SS) values within a narrow gate-source voltage ( V sg ) range. This study advances knowledge on how the controlled-phase doped HZO films affect the dielectric constant and leakage current and will contribute to semiconductor technology advancements by overcoming the limitations of conventional high-k dielectric insulators.

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have demonstrated a blood pressure (BP) reduction benefit despite other indications for use. We evaluated BP changes and antihypertensive medication use pre- and post-SGLT2i initiation among 12 960 patients with treated hypertension and among subgroups with apparent treatment-resistant hypertension (aTRH) and/or proteinuria. Post-SGLT2i initiation, the mean (SD) systolic blood pressure (SBP) was reduced from 133.9 (16.4) to 128.6 (15.5) mmHg and the mean diastolic blood pressure (DBP) was reduced from 70.8 (11.8) to 68.3 (11.3) mmHg among all patients. The mean SBP/DBP reduction was 5.3/2.5, 6.2/2.8, and 6.1/2.9 mmHg among all patients, patients with aTRH, and patients with proteinuria, respectively. Achieved BP < 130/80 mmHg increased by 12.5%, 16.9%, and 11.1% for all patients, patients with aTRH, and patients with proteinuria, respectively. Discontinuation of ≥ 1 antihypertensive medication within 12 months of SGLT2i initiation occurred in 33.4% overall, 47.6% of patients with aTRH, and 38.7% of patients with proteinuria., (© 2024 The Author(s).

Background: Discrimination against lesbian, gay, bisexual, transgender, queer or questioning, and other sexual and gender diverse (LGBTQ+) individuals in healthcare settings remains a priority issue. Nurse leaders, who oversee the largest healthcare workforce, are critical in implementing inclusive practices to address LGBTQ+ discrimination, yet implementing LGBTQ+ inclusive practices and effective strategies is inconsistent. This qualitative descriptive study explored nurse leaders' perceptions of LGBTQ+ inclusive practices across the United States to inform recommended strategies within health systems., Methods: Twenty-one nurse leaders (e.g., chief nurse executives) from diverse healthcare settings (e.g., children's hospitals and public health centers) in 12 states across the United States participated in semi-structured interviews from October to December 2023. Interview transcripts were analyzed using content analysis to (1) describe nurse leaders' definitions of LGBTQ+ inclusive practices and (2) identify effective strategies for their implementation., Results: Nurse leaders defined LGBTQ+ inclusive practices to include delivering culturally responsive and competent care, fostering safe and affirming environments, integrating inclusivity into daily interactions and organizational culture, and supporting the needs of both LGBTQ+ staff and patients. Key implementation strategies included fostering a flexible organizational culture through open communication; a diverse workforce; and inclusive mission statements, policies, and strategic plans. Supportive infrastructure involved effective LGBTQ+ training and adapting electronic health record systems to include information on sexual orientation and gender identity. Active and interdisciplinary engagement from staff and leadership, as well as systematic data collection on patient and staff experiences, were essential for driving inclusivity. The advocacy highlighted included legislative support, discourse within the nursing profession, and the incorporation of LGBTQ+ inclusion into healthcare regulations and accreditation standards. Additionally, multisectoral partnerships with LGBTQ+ health experts and external organizations, along with multilevel evaluations, were recommended to develop tailored interventions and promote LGBTQ+ inclusive practices., Conclusion: Implementing LGBTQ+ inclusive practices in healthcare is a multifaceted effort influenced by strategies at various levels. Promoting a supportive organizational culture, establishing comprehensive support structures, encouraging active engagement, and fostering community partnerships can address the needs of LGBTQ+ individuals more effectively. Future implementation efforts should tailor strategies to accommodate variability across healthcare settings and regions, ensuring that practices are both adaptable and sustainable., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Author(s).)

The e^{+}e^{-}→D&#95;{s}^{+}D&#95;{s1}(2536)^{-} and e^{+}e^{-}→D&#95;{s}^{+}D&#95;{s2}^{*}(2573)^{-} processes are studied using data samples collected with the BESIII detector at center-of-mass energies from 4.530 to 4.946 GeV. The absolute branching fractions of D&#95;{s1}(2536)^{-}→D[over ¯]^{*0}K^{-} and D&#95;{s2}^{*}(2573)^{-}→D[over ¯]^{0}K^{-} are measured for the first time to be (35.9±4.8±3.5)% and (37.4±3.1±4.6)%, respectively. The e^{+}e^{-}→D&#95;{s}^{+}D&#95;{s1}(2536)^{-} and e^{+}e^{-}→D&#95;{s}^{+}D&#95;{s2}^{*}(2573)^{-} cross sections are measured, and a resonant structure at around 4.6 GeV with a width of 50 MeV is observed in both processes with a statistical significance of 7.2σ and 15σ, respectively. The state is observed for the first time in e^{+}e^{-}→D&#95;{s}^{+}D&#95;{s2}^{*}(2573)^{-} and could be the Y(4626) found by the Belle oration in the D&#95;{s}^{+}D&#95;{s1}(2536)^{-} final state, since they have similar masses and widths. There is also evidence for a structure at around 4.75 GeV in both processes.

Background: The Pooled Cohort Equations (PCEs) do not accurately estimate atherosclerotic cardiovascular disease (ASCVD) risk in certain populations. The 2018 AHA/ACC cholesterol guideline identified risk-enhancing factors as a supplement to PCEs-based risk assessment. However, the role of each risk-enhancing factor in ASCVD risk assessment has not been well quantified. Further, social determinants of health (SDOH) are not included in the PCEs nor considered as risk-enhancing factors in the US cholesterol guideline. We sought to evaluate ASCVD risk associated with each risk-enhancing factor and commonly collected SDOH including education, income, and employment status, and to assess if adding risk-enhancing factors and SDOH to the PCEs improve ASCVD risk prediction., Methods: We included individuals aged 40 to 75 years, without ASCVD or diabetes at baseline, and with low-density lipoprotein cholesterol 70-189 mg/dL from two contemporary prospective cohort studies (MESA and REGARDS) and from Kaiser Permanente Southern California (KPSC). The primary endpoint was incident ASCVD defined as nonfatal myocardial infarction, fatal coronary heart disease, or fatal or nonfatal stroke over a 10-year period (median follow-up 10 years). We used Cox proportional hazards models to estimate associations between risk-enhancing factors and SDOH with ASCVD. We also assessed changes in model performance after adding risk-enhancing factors and SDOH to the PCEs., Results: We included 13,863 adults (mean age 60.7 years) from the prospective cohorts and 307,931 adults (mean age 54.8 years) from KPSC. Risk-enhancing factors including hypercholesterolemia, hypertriglyceridemia, metabolic syndrome, and chronic kidney disease were associated with a higher ASCVD risk, independent of 10-year risk estimated by the PCEs. Low education, low income, and unemployment were also associated with higher ASCVD risk. While adding individual risk-enhancing factors or SDOH to the PCEs had limited impact on model performance, adding multiple risk-enhancing factors and SDOH simultaneously led to modest improvements in discrimination (C-index increased by up to 0.07), calibration (integrated Brier score reduced by up to 2.3%), and net reclassification improvement up to 41.4%., Conclusions: These findings suggest including SDOH and risk-enhancing factors may improve ASCVD risk assessment., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests: LDC receives research support from Amgen, unrelated to this work., (Copyright: © 2024 Zhang et al.

Piezo1 mechanosensitive ion channel plays a important role in vascular physiology and disease. This study aimed to elucidate the altered signaling elicited by Piezo1 activation in the arteries of type 2 diabetes. Ten- to 12-week-old male C57BL/6 (control) and type 2 diabetic mice (db - /db - ) were used. The second-order mesenteric arteries (~ 150 μm) were used for isometric tension experiments. Western blot analysis and immunofluorescence staining were performed to observe protein expression. Piezo1 was significantly decreased in mesenteric arteries of type 2 diabetic mice compared to control mice, as analyzed by western blot and immunofluorescence staining. Piezo1 agonist, Yoda1, concentration-dependently induced relaxation of mesenteric arteries in both groups. Interestingly, the relaxation response was significantly greater in control mice than in db - /db - mice. The removal of endothelium reduced relaxation responses induced by Yoda1, which was greater in control mice than db - /db - mice. Furthermore, the relaxation response was reduced by pre-treatment with various types of K + channel blockers in endothelium-intact arteries in control mice. In endothelium-denuded arteries, pre-incubation with charybdotoxin, an Ca 2+ -activated K + channel (BK Ca channel) blocker, significantly attenuated Yoda1-induced relaxation in db - /db - mice, while there was no effect in control mice. Co-immunofluorescence staining showed co-localization of Piezo1 and BK Ca channel was more pronounced in db - /db - mice than in control mice. These results indicate that the vascular responses induced by Piezo1 activation are different in the mesenteric resistance arteries in type 2 diabetic mice., (© 2024. The Author(s).)

The management of unknown weapons obtained from warfare, military operations, and terrorist situations requires a series of nondestructive testing processes. This management process, which is aimed at collecting information on the nature of the weapons, encompasses identification, processing, transportation, and storage of the obtained weapons. A lack of identification marks in acquired ammunition may indicate the potential presence of a chemical weapon. Therefore, nondestructive evaluation methods have been employed to identify unknown weapons. However, these methods rely on neutron- and radiation-based analyses, which require radiation-handling experts and specific protective facilities. Consequently, their application in this field is challenging. Herein, a nondestructive ultrasonic testing method, which can identify substances inside unknown weapons and optimize the verifiability of the state of the ammunition, was employed as an alternative method to overcome these limitations. The experimental system enabled quantitative and qualitative analyses of the internal chemicals by analyzing the time difference in acquiring the signals, particularly when the results indicate that the internal substance is a liquid. The results of this study can serve as a basis for advancing the application of ultrasonic testing as a viable and efficient approach for managing unknown weapons., (© 2024. The Author(s).)

We measure the complete set of angular coefficients J&#95;{i} for exclusive B[over ¯]→D^{*}ℓν[over ¯]&#95;{ℓ} decays (ℓ=e, μ). Our analysis uses the full 711  fb^{-1} Belle dataset with hadronic tag-side reconstruction. The results allow us to extract the form factors describing the B[over ¯]→D^{*} transition and the Cabibbo-Kobayashi-Maskawa matrix element |V&#95;{cb}|. Using recent lattice QCD calculations for the hadronic form factors, we find |V&#95;{cb}|=(40.7±0.7)×10^{-3} using the Boyd-Grinstein-Lebed parametrization, compatible with determinations from inclusive semileptonic decays. We search for lepton flavor universality violation as a function of the hadronic recoil parameter w and investigate the differences of the electron and muon angular distributions. We find no deviation from standard model expectations.

Using 7.33  fb^{-1} of e^{+}e^{-} collision data collected by the BESIII detector at center-of-mass energies in the range of sqrt[s]=4.128-4.226  GeV, we search for the rare decays D&#95;{s}^{+}→h^{+}(h^{0})e^{+}e^{-}, where h represents a kaon or pion. By requiring the e^{+}e^{-} invariant mass to be consistent with a ϕ(1020), 0.98

The J/ψ, ψ(3686)→Σ^{0}Σ[over ¯]^{0} processes and subsequent decays are studied using the world's largest J/ψ and ψ(3686) data samples collected with the BESIII detector. The parity-violating decay parameters of the decays Σ^{0}→Λγ and Σ[over ¯]^{0}→Λ[over ¯]γ, α&#95;{Σ^{0}}=-0.0017±0.0021±0.0018 and α[over ¯]&#95;{Σ^{0}}=0.0021±0.0020±0.0022, are measured for the first time. The strong CP symmetry is tested in the decays of the Σ^{0} hyperons for the first time by measuring the asymmetry A&#95;{CP}^{Σ}=α&#95;{Σ^{0}}+α[over ¯]&#95;{Σ^{0}}=(0.4±2.9±1.3)×10^{-3}. The weak CP test is performed in the subsequent decays of their daughter particles Λ and Λ[over ¯]. Also for the first time, the transverse polarizations of the Σ^{0} hyperons in J/ψ and ψ(3686) decays are observed with opposite directions, and the ratios between the S-wave and D-wave contributions of the J/ψ, ψ(3686)→Σ^{0}Σ[over ¯]^{0} decays are obtained. These results are crucial to understand the decay dynamics of the charmonium states and the production mechanism of the Σ^{0}-Σ[over ¯]^{0} pairs.

We present the results of a search for the b→dℓ^{+}ℓ^{-} flavor-changing neutral-current rare decays B^{+,0}→(η,ω,π^{+,0},ρ^{+,0})e^{+}e^{-} and B^{+,0}→(η,ω,π^{0},ρ^{+})μ^{+}μ^{-} using a 711  fb^{-1} data sample that contains 772×10^{6}  BB[over ¯] events. The data were collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. We find no evidence for signal and set upper limits on branching fractions at the 90% confidence level in the range (3.8-47)×10^{-8} depending on the decay channel. The obtained limits are the world's best results. This is the first search for the channels B^{+,0}→(ω,ρ^{+,0})e^{+}e^{-} and B^{+,0}→(ω,ρ^{+})μ^{+}μ^{-}.

Background: We investigated the impacts of tocolytic agents on maternal and neonatal blood glucose levels in women with gestational diabetes mellitus (GDM) who used tocolytics for preterm labor., Methods: This multi-center, retrospective cohort study included women with GDM who were admitted for preterm labor from twelve hospitals in South Korea. We excluded women with multiple pregnancies, anomalies, overt DM diagnosed before pregnancy or 23 weeks of gestation, and women who received multiple tocolytics. The patients were divided according to the types of tocolytics; atosiban, ritodrine, and nifedipine group. We collected baseline maternal characteristics, pregnancy outcomes, maternal glucose levels during hospitalization, and neonatal glucose levels. We compared the frequency of maternal hyperglycemia and neonatal hypoglycemia among three groups. A multivariate logistic regression analysis was performed to evaluate the contributing factors to the occurrence of maternal hyperglycemia and neonatal hypoglycemia., Results: A total of 128 women were included: 44 (34.4%), 51 (39.8%), and 33 (25.8%) women received atosiban, ritodrine, and nifedipine, respectively. Mean fasting blood glucose (FBG) (112.3, 109.6, and 89.5 mg/dL, P < 0.001) and 2-hour postprandial glucose (PPG2) levels (145.4, 148.3, and 116.5 mg/dL, P = 0.004) were significantly higher in atosiban and ritodrine group than those in nifedipine group. Even after adjusting for covariates including antenatal steroid use, gestational age at admission, and pre-pregnancy body mass index, there was an increased risk of high maternal mean FBG (≥ 95 mg/dL) and PPG2 (≥ 120 mg/dL) levels in the atosiban and ritodrine group than in nifedipine group. The atosiban and ritodrine groups are also at increased risk of neonatal hypoglycemia (< 47 mg/dL) compared to the nifedipine group with the odds ratio of 4.58 and 4.67, respectively ( P < 0.05)., Conclusion: There is an increased risk of maternal hyperglycemia and neonatal hypoglycemia in women with GDM using atosiban and ritodrine tocolytics for preterm labor compared to those using nifedipine., Competing Interests: Hyun Soo Park and Hyun-Joo Seol participated in the Tractocile (atosiban) Advisory Board and received consulting fees from Ferring Pharmaceuticals Korea on October 24, 2023.

Background/aim: Skin wound healing is a physiological process restoring the structural and functional integrity of injured skin. During this process, wound management preventing bacterial infection and complications is important for the regeneration of skin layers and adnexa, as well as the protective function of the skin. Therefore, the development of an effective ointment to promote wound healing without complications is beneficial., Materials and Methods: This study developed Raepenol™ cream, comprising a base cream and natural compounds including paeonol, D-panthenol and extract of Centella asiatica, and assessed its therapeutic effect in wound healing. A rat model of skin wound healing and a mouse model of imiquimod-induced pruritus were employed. The effect of Raepenol™ cream was evaluated by wound size and histological analysis, including the integrity of skin structures and inflammatory response., Results: Raepenol™ cream treatment effectively restored the structural integrity of the skin in rats, including wound closure, regeneration of skin adnexa, and reconstitution of collagen, comparable to commercial ointment. Additionally, Raepenol™ cream significantly suppressed pruritus by inhibiting mast cell infiltration or retention in the inflammatory site of mouse ears., Conclusion: Raepenol™ cream effectively promoted wound healing and relieved pruritus in animal models. These results suggest that it could be a promising option for wound care and pruritus relief, offering potential advantages over current ointments., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.
