Abstract
OBJECTIVES Despite the cultural importance of marriage as a social support system and its well-established link to mental health, older Hispanic adult populations, which are the largest racial and ethnic minoritized groups, remain understudied. The current study examined how positive and negative dimensions of marital quality are associated with depressive symptoms. METHODS Data from Hispanic adults aged 51 years and older (n = 1,012) were obtained from the 2016 and 2018 Health and Retirement Study waves. The Center for Epidemiological Studies-Depression scale (0-8 symptoms) was modeled as a function of positive and negative marital quality measures (1-4), as well as the relevant covariates. RESULTS Results from a negative binomial regression model showed that a 1-unit change in positive and negative marital quality was associated with a 23.61% reduction and a 23.74% increase, respectively, in depressive symptoms. The interaction terms with marital quality and gender, as well as marital quality and religion, were not statistically significant. DISCUSSION In the United States, a large percentage of older Hispanic adults are immigrants, and their extended family tends to reside in their countries of origin. As such, older Hispanic adults may have smaller social networks, and marital quality most likely represents a culturally important social support network in later life. Significant associations between depressive symptoms and marital quality among older Hispanic adults should receive more attention in family and public health policy discussions, particularly given the increasing diversity in U.S. society.

Abstract
The subpopulation of adults depends on non-online health information sources including their social networks and health professionals, to the exclusion of online sources. In view of the digital divide and health information disparities, the roles of race/ethnicity and digital skills are yet to be explored. A nationally representative sample of 6,830 adults from the Program for the International Assessment of Adult Competencies (PIAAC) was analyzed, using binary logistic regression. Black adults and adults with higher digital skills were less likely to be reliant on non-online health information sources, compared to White adults and those with lower digital skills, respectively. Differences in non-online health information source reliance by race/ethnicity and digital skills might be further nuanced by the relevant demographic and socioeconomic characteristics. Increasing digital skills may expand one's health information sources to include reliable online sources and empower adults to promote their health.

Abstract
In recent years, the medical use of cannabinoids has attracted growing attention worldwide. In particular, anti-inflammatory properties of cannabinoids led to their emergence as potential therapeutic options for autoimmune and inflammatory disorders. Recent studies have also shown that cannabinoid receptors are widely expressed and have endogenous ligands in the skin, suggesting that the skin has its own endocannabinoid system. The aim of this review is to discuss the potential therapeutic effects of cannabinoids in autoimmune and inflammatory skin diseases. Following an overview of cannabinoids and the endocannabinoid system, we describe the cellular and molecular mechanisms of cannabinoids in skin health and disease. We then review the clinical studies of cannabinoids in autoimmune and inflammatory skin diseases including systemic sclerosis (SSc), dermatomyositis (DM), psoriasis (Pso) and atopic dermatitis (AD). A primary literature search was conducted in July 2023, using PubMed and Web of Science. A total of 15 articles were included after excluding reviews, non-human studies and in vitro studies from 389 non-duplicated articles. Available evidence suggests that cannabinoids may be beneficial for SSc, DM, Pso and AD. However, further studies, ideally randomized controlled trials, are needed to further evaluate the use of cannabinoids in autoimmune and inflammatory skin diseases.

Abstract
BACKGROUND Primary analysis of the multicenter, open-label, single-arm, phase II DESTINY-Breast01 trial (median follow-up 11.1 months) demonstrated durable antitumor activity with trastuzumab deruxtecan (T-DXd) in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (mBC) previously treated with trastuzumab emtansine (T-DM1). We report updated cumulative survival outcomes with a median follow-up of 26.5 months (data cut-off 26 March 2021). PATIENTS AND METHODS Patients with HER2-positive mBC resistant or refractory to T-DM1 received T-DXd 5.4 mg/kg intravenously every 3 weeks until disease progression, unacceptable adverse events, or withdrawal of consent. The primary endpoint was confirmed objective response rate (ORR) by independent central review (ICR). Secondary endpoints included overall survival (OS), duration of response (DoR), progression-free survival (PFS), and safety. RESULTS The ORR by ICR was 62.0% [95% confidence interval (CI) 54.5% to 69.0%] in patients who received T-DXd 5.4 mg/kg every 3 weeks (n = 184). Median OS was 29.1 months (95% CI 24.6-36.1 months). Median PFS and DoR were 19.4 months (95% CI 14.1-25.0 months) and 18.2 months (95% CI 15.0 months-not evaluable), respectively. Drug-related treatment-emergent adverse events (TEAEs) were observed in 183 patients (99.5%), and 99 patients (53.8%) had one or more grade ≥3 TEAEs. Adjudicated drug-related interstitial lung disease/pneumonitis occurred in 15.8% of patients (n = 29), of which 2.7% (n = 5) were grade 5. CONCLUSIONS These updated results provide further evidence of sustained antitumor activity of T-DXd with a consistent safety profile in heavily pretreated patients with HER2-positive mBC.

Abstract
BACKGROUND Actinomycosis is a clinically significant but uncommon infectious disease caused by anaerobic commensals of Actinomyces species, and the incidence of thoracic empyema is rare. We report an extremely rare case of empyema caused by Actinomyces naeslundii (A. naeslundii). CASE REPORT A 39-year-old man presented to our hospital with fever and dyspnea. He had massive pleural effusion and was diagnosed with a left lower-lobe abscess and left thoracic empyema. Thoracic drainage was performed and Ampicillin/Sulbactam was administered for 3 weeks. Four years later, the patient presented with back pain, and chest X-ray showed increased left pleural effusion. After close examination, malignant pleural mesothelioma was suspected, and computed tomography-guided needle biopsy was performed, which yielded a viscous purulent pleural effusion with numerous greenish-yellow sulfur granules. A. naeslundii was identified through anaerobic culture. Thoracoscopic surgery of the empyema cavity was conducted, and Ampicillin/Sulbactam followed by Amoxicillin/Clavulanate was administered for approximately 6 months. No recurrence has been observed for 1 year since the surgical procedure. CONCLUSIONS Actinomyces empyema is a rare condition, and this case is the second reported occurrence of empyema caused by A. naeslundii. The visual identification of sulfur granules contributed to the diagnosis. Long-term antibiotic therapy plays a crucial role in treatment.

Abstract
Few studies have made direct comparisons between treatments for palmoplantar pustulosis (PPP); therefore, it is difficult to select the best treatment for each patient. To determine the best therapy and to compare reported measures of efficacy in clinical trials of systemic treatments for PPP in this systematic review and network meta-analysis. Six databases were used to perform database search on 10 July 2022. Randomized controlled trials (RCTs) were identified through a systematic literature search. The titles and abstracts of articles were initially screened for inclusion by two authors independently using our predetermined criteria. The full texts of selected articles were then independently assessed for inclusion in a blinded fashion. Disagreement between the authors was resolved by consensus. Data were abstracted in duplicate. Random-effects model was accepted to perform network meta-analysis. Assessed Grading of Recommendations Assessment, Development and Evaluation certainty of evidence were performed according to the PRISMA guidelines. The analysis was completed in July 2022. The primary outcome was the change of PPP Area and Severity Index (PPPASI) from baseline and the secondary outcome was the achievement of PPPASI-50 response. Seven RCTs with 567 patients were included. Guselkumab 100 mg was the one with the highest probability of reaching the proposed outcomes (mean difference [MD], -8.00; 95% confidence interval [CI], 4.88-11.11), while the achievement of PPPASI-50 response did not show a significant difference (odds ratio [OR], 3.79; 95% CI, 0.51-28.37). Guselkumab 200 mg was next to 100 mg of reaching the proposed outcomes (MD, -4.71; 95% CI, 2.12-7.30), while the achievement of PPPASI-50 response did not show a significant difference (OR, 2.34; 95% CI, 0.48-11.43). Network meta-analysis showed guselkumab 100 mg was the treatment with the highest probability of reaching both PPPASI and PPPASI-50 outcomes. Absolute PPPASI may be more appropriate as an outcome than PPPASI-50.

Abstract
A 23-year-old female with a history of idiopathic epilepsy was found to have a right chest cavity shadow in a school health checkup 5 years before. CT revealed a thin-walled cavity lesion in the right middle lobe containing a ball-like mass, showing air crescent sign. After falling due to a seizure, she was transported by ambulance and admitted. CT revealed diffuse ground-glass opacities throughout the right lung field. Bronchoscopy revealed bloody bronchial alveolar lavage fluid. Due to the tumor hemorrhage, an elective simple right middle lobe resection was performed without complications. The initial immunohistochemical staining was negative for ALK using ALK1 clone; however, subsequent staining of ALK by D5F3 and 5A4 clone was positive. Immunostaining findings led to a diagnosis of inflammatory myofibroblastic tumor. The patient remains under regular observation and has experienced no recurrence over the 6-year postoperative period. This case contains two different points: the first is that a cavity lesion of inflammatory myofibroblastic tumor may cause traumatic bleeding and should be treated with caution; the second is that attention should be paid to differences in stainability among clones when diagnosing inflammatory myofibroblastic tumor.

Abstract
BACKGROUND At present, relatively few lung surgeries are performed without endostaplers. Although there are few staple-related adverse events, severe events must be shared to improve safety. CASE PRESENTATION A 74-year-old male suddenly collapsed and was transferred to the Emergency Rescue department. He had shock vitals and contrast-enhanced CT revealed extensive right hemothorax with contrast leakage. He lost consciousness and tension massive hemothorax was suspected. We performed emergency thoracotomy at two sites and were able to achieve hemostasis and save the patient. Upon examining the patient's medical history after his condition stabilized, it was revealed that he was a lung cancer patient who was taking ramucirumab and cilostazol. In addition, the CT scan taken one month before onset revealed the bleeding site of the fifth intercostal artery were almost contact with the staple line from a prior right spontaneous pneumothorax surgery that was performed 11 years previously, which was seemed to damage the intercostal artery. CONCLUSION Despite the difficulty in achieving hemostasis due to drug administration history, we successfully treated a case of remote period massive hemothorax attributed to staples, thereby saving the patient. When using drugs that increase the risk of bleeding events, it may be important to consider the position of the staple line while assessing the risk. In the emergent or ICU setting, if the initial incision is not effective, the placement of a new second incision may be valuable.

Abstract
BACKGROUND Pustulotic arthro-osteitis (PAO) is 1 of the most serious comorbidities associated with palmoplantar pustulosis (PPP). Risk factors of PAO development are not well-known. OBJECTIVE To evaluate the clinical significance of nailfold capillary (NFC) changes in patients with PPP. METHODS We conducted a prospective cohort study in a population of 102 PPP patients. Correlations of NFC abnormalities, including nailfold bleeding and enlarged capillaries, with the prevalence of PAO, the incidence of new PAO, and serum levels of cytokines were analyzed. RESULTS Detailed examination revealed that of 102 PPP patients, 52 without PAO and 50 with PAO. Both nailfold bleeding and enlarged capillaries were significantly more frequent in patients with PAO (50.0% vs 92.0%, P < .0001; 50.0% vs 94.0%, P < .0001). In addition, PPP patients without PAO were prospectively observed before they developed PAO (mean 28 months [1-52 months]). Multivariate analysis suggested that these NFC abnormalities were predictors of PAO development (hazard ratio 3.37, 95% confidence interval 1.13-10.07; 3.37, 1.13-10.07) and guselkumab prevent PAO development (0.093, 0.012-0.76). The degree of NFC abnormalities correlated with the severity of PAO and serum cytokine levels. LIMITATIONS All participants were Japanese. CONCLUSION NFC abnormalities could be predictors of PAO in PPP patients, and their degree indicators of disease severity.

Abstract
Introduction As a form of precision medicine, this study aimed to investigate the specific patient population that would derive the greatest benefit from tildrakizumab, as well as the mechanism of action and efficacy of tildrakizumab in reducing the occurrence of psoriatic arthritis (PsA). Methods To achieve this, a multi-center, prospective cohort study was conducted, involving a population of 246 psoriasis patients who had not received any systemic therapy or topical finger therapy between January 2020 and April 2023. Two independent clinicians, who were blinded to the study, analyzed nailfold capillary (NFC) abnormalities, such as nailfold bleeding (NFB) and enlarged capillaries, as well as the incidence of new PsA. Additionally, the factors that determined the response of psoriasis after seven months of tildrakizumab treatment were examined. The study also examined the quantity and role of regulatory T cells (Tregs) and T helper 17 cells both pre- and post-treatment. Results The severity of psoriasis, as measured by the Psoriasis Area and Severity Index (PASI), was found to be more pronounced in the tildrakizumab group (n=20) in comparison to the topical group (n=226). At 7 months after tildrakizumab treatment, multivariate analysis showed that those 65 years and older had a significantly better response to treatment in those achieved PASI clear or PASI 2 or less (Likelihood ratio (LR) 16.15, p<0.0001; LR 6. 16, p=0.01). Tildrakizumab improved the number and function of Tregs, which had been reduced by aging. Tildrakizumab demonstrated significant efficacy in improving various pathological factors associated with PsA. These factors include the reduction of NFB, enlargement of capillaries, and inhibition of PsA progression. The hazard ratio for progression to PsA was found to be 0.06 (95% confidence interval: 0.0007-0.46, p=0.007), indicating a substantial reduction in the risk of developing PsA. Discussion Tildrakizumab's effectiveness in improving skin lesions can be attributed to its ability to enhance the number and function of Tregs, which are known to decline with age. Furthermore, the drug's positive impact on NFB activity and capillary enlargement, both of which are recognized as risk factors for PsA, further contribute to its inhibitory effect on PsA progression.

Abstract
This study examines breast cancer screening behavior among subpopulations of Black women in the United States. Binary logistic regression was used to analyze breast cancer screening among a nationally-representative sample (n = 9,783) of Black women-US-born, non-US-born Caribbean, and non-US-born African-from the 2011-2017 National Health Interview Survey dataset. Non-US-born African Black women were less likely to have breast cancer screening, compared to US-born Black women. Among non-US-born Black women, non-US-born Caribbean Black women were more likely to have had breast cancer screening. Differential healthcare access associated with nativity differences among Black women can be informing their breast cancer screening behaviors. Efforts to improve breast cancer outcomes among Black women can benefit from interventions that account for differential access to healthcare and breast cancer screening behaviors among subgroups of Black women.

Abstract
Comprehensive autoantibody evaluation is essential for the management of autoimmune disorders. However, conventional methods suffer from poor sensitivity, low throughput, or limited availability. Here, using a proteome-wide human cDNA library, we developed a novel multiplex protein assay (autoantibody array assay; A-Cube) covering 65 antigens of 43 autoantibodies that are associated with systemic sclerosis (SSc) and polymyositis/dermatomyositis (PM/DM). The performance of A-Cube was validated against immunoprecipitation and established enzyme-linked immunosorbent assay. Further, through an evaluation of serum samples from 357 SSc and 172 PM/DM patients, A-Cube meticulously illustrated a diverse autoantibody landscape in these diseases. The wide coverage and high sensitivity of A-Cube also allowed the overlap and correlation analysis between multiple autoantibodies. Lastly, reviewing the cases with distinct autoantibody profiles by A-Cube underscored the importance of thorough autoantibody detection. Together, these data highlighted the utility of A-Cube as well as the clinical relevance of autoantibody profiles in SSc and PM/DM.

Abstract
BACKGROUND Systemic sclerosis (SSc) is divided into diffuse and limited cutaneous SSc (dcSSc and lcSSc). The dcSSc subtype has more severe internal organ damage. This study aimed to assess whether cardiovascular magnetic resonance (CMR) parametric mapping could detect early cardiac involvement and evaluate differences between these two subtypes. METHODS Eighty SSc patients (37 dcSSc and 43 lcSSc) underwent CMR at 3.0 T (Philips Healthcare, Best, The Netherlands) in our hospital between July 2018 and July 2021. We analyzed myocardial damage by CMR parametric mapping and compared it with clinical data. RESULTS The median duration of the disease was 10.2 months. The left ventricular ejection fraction was preserved in both groups. DcSSc had significantly higher native T1 (1333.4 ± 71.2 ms vs. 1295.0 ± 42.7 ms, p = 0.006) and extracellular volume fraction (32.6 ± 4.1 % vs. 30.3 ± 4.0 %, p = 0.018) in the mid-ventricular septum as compared to lcSSc, although there were no differences in T2 values. Native T1 values were positively correlated with the E/e' ratio and left atrial volume indices evaluated by transthoracic echocardiography in overall SSc and dcSSc, but not in lcSSc. Logistic regression analysis revealed that native T1 was an independent predictor of left ventricular diastolic dysfunction in SSc patients (odds ratio, 1.194; 95 % confidence interval, 1.021-1.396; p = 0.026). Native T1 was higher in SSc patients with progressive skin lesions. Additionally, there were positive correlations between brain natriuretic peptide, New York Heart Association functional classification, and native T1. CONCLUSIONS CMR parametric mapping is a useful tool for detecting myocardial changes. Native T1 was the most sensitive parameter for identifying diffuse myocardial changes in the early stages of SSc and was associated with left ventricular diastolic function. DcSSc had more severe myocardial involvement than lcSSc; therefore, the use of CMR parametric mapping may aid in its prediction.

Abstract
In patients with unresectable non-small cell lung cancer, histological diagnosis is frequently based on small biopsy specimens unsuitable for histological diagnosis when they are severely crushed and do not retain their morphology. Therefore, establishing a novel diagnostic method independent of tissue morphology or conventional immunohistochemistry (IHC) markers is required. We analyzed the lipid profiles of resected primary lung adenocarcinoma (ADC) and squamous cell carcinoma (SQCC) specimens using liquid chromatography-tandem mass spectrometry. The specimens of 26 ADC and 18 SQCC cases were evenly assigned to the discovery and validation cohorts. Non-target screening on the discovery cohort identified 96 and 13 lipid peaks abundant in ADC and SQCC, respectively. Among these 109 lipid peaks, six and six lipid peaks in ADC and SQCC showed reproducibility in target screening on the validation cohort. Finally, we selected three and four positive lipid markers for ADC and SQCC, demonstrating high discrimination abilities. In cases difficult to diagnose by IHC staining, [cardiolipin(18:2_18:2_18:2_18:2)-H]- and [triglyceride(18:1_17:1_18:1) + NH4]+ showed the excellent diagnostic ability for ADC (sensitivity: 1.00, specificity: 0.89, accuracy: 0.93) and SQCC (sensitivity: 0.89, specificity: 0.83, accuracy: 0.87), respectively. These novel candidate lipid markers may contribute to a more accurate diagnosis and subsequent treatment strategy for unresectable NSCLC.

Abstract
In the current system, the disposal of plastic materials causes serious environmental pollution such as the generation of carbon dioxide and destruction of the ecosystem by micro-plastics. To solve this problem, bioplastics, biomass and biodegradable plastics have been developed. As part of our research, we have developed novel bioplastics called "cell-plastics", in which a unicellular green algal cell serves as a fundamental resource. The production of the cell-plastics would be expected to reduce environmental impact due to the usage of a natural product. Herein, to overcome the mechanical strength of cell-plastics, we used thermosetting epoxy and urethane resins containing Chlorella sp. as the green algae. We successfully fabricated thermosetting resins with a Chlorella sp. content of approximately 70 wt% or more. IR measurements revealed that the chemical structure of an epoxide or isocyanate monomer mixed with Chlorella sp. was modified, which suggests that the resins were hardened by the chemical reaction. In addition, we investigated the effect of thermosetting conditions such as temperature and compression for curing both resins. It was revealed that the Young's moduli and tensile strengths were controlled by thermosetting temperature and compression, whereas the elongation ratios of the resins were constant at low values regardless of the conditions.

Abstract
Systemic inflammation plays a central role in the pathophysiology of psoriasis. This study examined accessible systemic inflammatory markers in patients with psoriasis vulgaris and psoriatic arthritis. We aimed to evaluate their association with psoriasis severity, the presence of arthritis, and drug continuation rates. The findings revealed that neutrophil, monocyte, and platelet count, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, systemic inflammation response index, systemic immune/inflammation index (SII), and CRP were positively correlated with Psoriasis Area and Severity Index scores. Patients presenting with higher platelet/lymphocyte ratio (PLR) or CRP values were more likely to be diagnosed with psoriatic arthritis than with psoriasis vulgaris in the multivariate regression analysis. Importantly, patients with higher pretreatment neutrophil or platelet count, PLR, and SII were associated with lower treatment continuation rates of conventional systemic agents. Higher pretreatment scores of systemic inflammatory markers did not affect treatment retention rates of biologics. These findings suggest that several accessible systemic inflammatory markers may effectively assess underlying systemic inflammation and may provide an indication for a therapeutic approach in patients with psoriasis vulgaris and psoriatic arthritis.

Abstract
BACKGROUND Epithelioid sarcoma is a rare tumor and that is extremely rare as a primary pleural neoplasm. On imaging, it may appear similar to malignant pleural mesothelioma; thus, it can be difficult to diagnose. CASE REPORT A 64-year-old Asian woman, who had a treatment history of cervix adenocarcinoma, was admitted with dyspnea and right massive pleural effusion. Chest drainage was performed, and malignant cells were found in the pleural effusion. The malignant cells were thought to be metastasized from previous cervical cancer. We continued pleural drainage; however, the volume of the pleural effusion did not decrease. On the 5th hospital day, the chest tube became occluded. Computed tomography showed structures similar to empyema. Pleural irrigation and fibrinolytic therapy did not improve her condition. Empyema curettage was performed on the 14th hospital day. The resected pleura was submitted for pathological examination and showed tumor lesion but not metastatic adenocarcinoma of the cervix. The intrathoracic tumor grew extremely rapidly, and the patient died of respiratory failure on postoperative day 8 (22nd hospital day) before a diagnosis could be made. The final pathological diagnosis obtained on the 34th hospital day was epithelioid sarcoma. CONCLUSIONS For patients who appear to have empyema complicated by neoplastic lesions, a histopathological examination should also be performed to ensure accurate diagnosis. In addition, if a tumorous lesion is detected and it is neither metastatic nor malignant pleural mesothelioma, pleural epithelioid sarcoma should be added to the differential diagnosis in the presence of a rapidly growing and histologically difficult-to-diagnose pleural tumor.

Abstract
Background In severe blunt trauma, multiple organ injuries are often observed. Patients with a ruptured diaphragm and pericardium are referred to as having pericardio-diaphragmatic rupture. However, few studies have reported a narrowly defined case of connected rupture of the diaphragm and pericardium via their congenitally fused site along with an abdominal visceral herniation and cardiac luxation into the thoracic cavity. Case presentation A 78-year-old man presented to our hospital with left chest pain caused by a traffic accident. Contrast-enhanced computed tomography revealed a left diaphragmatic rupture and an intestinal herniation into the thoracic cavity. Surgical repair of the diaphragm was performed, and pericardial rupture was noted during surgery. It was considered that the laceration had spread via the congenitally fused site of the diaphragm and pericardium. The diaphragm was sutured, but the pericardium was left open because the laceration was large and the risk of cardiac incarceration was thought to be low. One year after the operation, no recurrence of diaphragmatic hernia was observed and any circulatory symptoms were not occurred. Conclusions In cases of diaphragmatic laceration extending to the fused site of the pericardium, connected pericardial rupture should also be considered. It would be challenging to detect without intraoperative findings, and it is desirable to observe both the thoracic and abdominal cavities.

Abstract
Abstract
Community colleges play an important role in training adults in healthcare-related occupations, such as nurses and medical technicians, to meet the needs of an aging population in the U.S. In addition, community colleges with open access policies, have a long-standing record of serving a diverse population, including students of all ages. However, the relatively low program completion rates (e.g., about 30% in Ohio) are of concern in general, and among older students in particular. One of the reasons for the low completion rate is the lack of postsecondary education readiness or basic skills, such as literacy, numeracy, and digital skills. The COVID-19 pandemic has created additional challenges, including faculty shortages, lack of internet access, poor digital skills, and transitions to online classes. This study examined characteristics of health-related occupational programs at community colleges located in Washington, Indiana, and Ohio, focusing on adult student characteristics, and their administrators' and faculty’s views on basic skills and program completion. In addition, potential employers were interviewed regarding the skill expectations of community college hires. Using the semi-structured qualitative interview, community college administrators, faculty, and potential employers reported that numeracy skills, excellent grammar, and critical thinking skills are important to succeed both in the classroom and in the workplace. Creating a supportive atmosphere in the classroom and providing tutoring, either by the instructor or at a tutoring center, are also important for student success. More detailed results as well as other policy implications are discussed in this study.

Abstract
Volunteer participation is a form of civic engagement that benefits both the individual and society over the life course. Although education, basic skills (e.g., literacy), and race/ethnicity are individually associated with volunteering, detailed interrelations are yet to be explored. Guided by the integrated theory of volunteer work and the notion of productive aging, the goal of this study was to examine the roles of education and adult literacy in the context of volunteering in later life across racial and ethnic groups (Whites, Blacks, Hispanics) in the U.S. Using the nationally representative sample of middle-aged and older adults (age 45+; n = 3,770) from the 2012/2014/2017 Program for International Assessment of Adult Competencies (PIAAC), structural equation modeling was constructed to evaluate mediation relationships among education, literacy, and volunteering by racial and ethnic groups. Results show no statistically significant mediation (a.k.a., indirect) effect of education on volunteering through literacy, nor was there statistically significant difference in the mediation effect across racial and ethnic groups. However, there were statistically significant differences in the direct effect of education on volunteering between Black adults and White adults [b(Black) = 0.44 versus b(White = 0.24), p < 0.05], as well as Black adults and Hispanic adults [b(Black) = 0.44 versus b(Hispanic) = 0.08, p < 0.05]. These findings indicate that higher education was more strongly associated with volunteering among older Black adults, compared to White and Hispanic counterparts. Suggested policy implications include support for the promotion of volunteer participation through culturally and socioeconomically sensitive approaches.

Abstract
In numeric information-rich societies, numeracy is essential both at work and in everyday life (e.g., calculating a budget). Numeracy skills generally decline with aging. Thus, among middle-aged and older workers, maintaining and improving numeracy skills is crucial to securing employment as well as managing everyday life. One of the counteracting strategies is to practice numeracy. However, little is known about how and what kinds of numeracy skills are used among older workers. We analyzed a nationally representative sample of U.S. workers aged 45 to 74 (n = 3,850) from the 2012/2014/2017 Program for International Assessment of Adult Competencies (PIAAC) restricted-use-file. Six dichotomous numeracy use indicators (e.g., calculating a budget, using advanced statistics) at work and in everyday life were considered. Survey weighted latent class analysis (LCA) identified three subgroups with distinctive numeracy skill use patterns, including ubiquitous (both at work and in everyday life) users, occupational users, and non-users. For example, calculating a budget was common both in non-users (40%) and ubiquitous users (84%), whereas uncommon among occupational users (25%). Also, only ubiquitous users practiced advanced math and statistics (14%), while others did not (nearly 0%). The subsequent regression analysis revealed that higher educational attainment, higher income, certain racial group (i.e., Whites), and better self-rated health were associated with greater numeracy skill use. The lack of numeracy skill use leads to lower skill levels and, in turn, social and economic disadvantages in later life. In addition to more detailed LCA results interpretations, possible policy and educational interventions are evaluated.

Abstract
It is essential to better understand older adults’ marital dynamics, as marital quality is consequential for older adults’ physical and mental health, relationships with other social network members, and risk of divorce. Although numerous studies examine marital quality during the early life course, much less is known about later life trajectories. Earlier work suggested marital quality followed a U-shaped curve, characterized by a later-life upswing, but more recent research finds patterns of stability or decline over time. Gender differences in marital quality are well established, but it is less clear whether older men and women experience different marital quality trajectories during later life. We use nationally-representative data from a sample of continuously-married adults over age 50 in the Health and Retirement Study (n=2,175) with measures of both positive and negative marital quality at three time points (2006, 2010, and 2014). Latent growth mixture models in Mplus estimate trajectories of marital quality over the eight-year time period. Results show small declines in both positive (b = -0.016, p < 0.05) and negative (b = -0.028, p < 0.05) marital quality over the observation period, but the declines in positive marital quality are limited to those in remarriages. Women have lower initial positive marital quality and higher initial negative marital quality than men, but there are no significant gender differences in change over time. Results support the stability and continuous-decline patterns of marital quality over the life course rather than a U-shaped curve, and suggest persistence of gender differences over time.

Abstract
In addition to autoimmune and inflammatory diseases, variants of the TNFAIP3 gene encoding the ubiquitin-editing enzyme A20 are also associated with fibrosis in systemic sclerosis (SSc). However, it remains unclear how genetic factors contribute to SSc pathogenesis, and which cell types drive the disease due to SSc-specific genetic alterations. We therefore characterize the expression, function, and role of A20, and its negative transcriptional regulator DREAM, in patients with SSc and disease models. Levels of A20 are significantly reduced in SSc skin and lungs, while DREAM is elevated. In isolated fibroblasts, A20 mitigates ex vivo profibrotic responses. Mice haploinsufficient for A20, or harboring fibroblasts-specific A20 deletion, recapitulate major pathological features of SSc, whereas DREAM-null mice with elevated A20 expression are protected. In DREAM-null fibroblasts, TGF-β induces the expression of A20, compared to wild-type fibroblasts. An anti-fibrotic small molecule targeting cellular adiponectin receptors stimulates A20 expression in vitro in wild-type but not A20-deficient fibroblasts and in bleomycin-treated mice. Thus, A20 has a novel cell-intrinsic function in restraining fibroblast activation, and together with DREAM, constitutes a critical regulatory network governing the fibrotic process in SSc. A20 and DREAM represent novel druggable targets for fibrosis therapy.

Abstract
Background
Atrial fibrillation (AF) is a risk factor for ischemic stroke (IS). We developed a novel risk score of IS (HELT-E2S2 score) in non-valvular atrial fibrillation (NVAF) patients from the combined database of 5 major AF registries in Japan. However, this score does not include echocardiographic (Echo) parameters that have been reported to be risk factors of IS, such as left atrial diameter (LAD) enlargement or increased relative wall thickness (RWT) of left ventricle (LV).
Purpose
To investigate the predictive value of Echo parameters in Japanese patients with NVAF.
Methods
After excluding patients without the Echo data, 6,032 NVAF patients were analyzed in the present study. LAD was measured in the parasternal long axis view at the end-ventricular systole. RWT was calculated as (2x posterior wall thickness)/ LV end-diastolic dimension. We compared clinical characteristics and the incidence of IS between NVAF patients divided by LAD level (High/Low LAD group) and RWT level (High/Low RWT group). To balance the follow-up period among the registries, event data from individuals whose follow-up period exceeded 730 days were excluded from the analysis.
Results
The optimal cut-off value of LAD and RWT to predict the incidence of IS with the receiver operating characteristic analysis was 43.3 mm and 0.4167, respectively. Between the High/Low LAD groups (High LAD: n=2,640 vs. Low LAD: n=3,392), age (70.3±12.1 vs. 68.3±12.5 years; p<0.001), CHA2DS2-VASc score (3.02±1.84 vs. 2.57±1.78; p<0.001), HELT-E2S2 score (2.20±1.31 vs. 1.55±1.33; p<0.001), the prescription of oral anticoagulants (OACs) (69.5 vs. 51.5%; p<0.001), LV ejection fraction (60.4±13.4 vs. 64.4±10.7%; p<0.001) and RWT (0.401±0.091 vs. 0.396±0.082; p=0.02) were significantly different. Between the High/Low RWT groups (High RWT: n=2,293 vs. Low RWT: n=3,739), percentage of female (35.6 vs. 27.8%; p<0.001), age (71.2±12.1 vs. 68.0±12.4 years; p<0.001), CHA2DS2-VASc score (3.08±1.82 vs. 2.58±1.79; p<0.001), HELT-E2S2 score (2.10±1.39 vs. 1.67±1.31; p<0.001), the prescription of OACs (62.6 vs. 57.4%; p<0.001), LV ejection fraction (65.5±9.9 vs. 60.9±13.0%; p<0.001) and LAD (43.0±8.1 vs. 42.4±8.3; p=0.004) were significantly different. In Kaplan-Meier analysis, the incidence of IS was different between the groups during the median follow-up period of 730 days (High LAD vs. Low LAD; 1.82 vs. 1.00 per 100 person-years; p<0.001, by log-rank test, High RWT vs. Low RWT; 1.86 vs. 1.06; p<0.001) (Figure). Both High LAD (hazard ratio: 1.65, 95% CI: 1.12–2.46; p=0.01) and High RWT (hazard ratio: 1.43, 95% CI: 1.01–2.04; p=0.045) were independent predictors of the incidence of IS after adjustment by the components of the HELT-E2S2 score and other clinically relevant variables including co-existing diseases, gender, and the prescription of OACs (Table).
Conclusion
Echo parameters, LAD and RWT, were independently associated with the incidence of IS among Japanese patients with NVAF.

Abstract
Abstract
Background
Radiomics is a comprehensive analysis methodology of medical image and involves the extraction of numerous features from standard imaging. Its usefulness has been reported mainly in the field of cancer for diagnosis and prediction of prognosis. In the territory of cardiac imaging, several reports have investigated the utility of radiomics for classifying the risk of prognosis in coronary artery disease, and few practical applications have been reported for patients with atrial fibrillation (AF) who underwent pulmonary vein isolation (PVI). Although the left atrial morphology can affect the clinical course after the PVI procedure, it is unclear whether the radiomics feature values of the left atrial morphology on cardiac computed tomography (CT) is useful for predicting the AF recurrence after PVI.
Purpose
To predict the recurrence of AF after PVI using the radiomics feature values of the left atrial morphology on cardiac computed tomography (CT).
Methods
We analyzed 525 consecutive three-dimensional cardiac CT in patients with atrial fibrillation who underwent PVI from 2018 to 2019 in our institute. After marking the region of interest on left atrium (including the root of pulmonary veins) semiautomatically, 107 radiomics feature values were obtained by Python program. After excluding the parameters having collinearity or with low predictive capability for the recurrence of AF after PVI, 42 parameters were applied to the final prediction model. Two prediction models were constructed by multivariate Cox regression analysis and machine learning model by support vector machine algorithm.
Results
The area under the curve (AUC) for predicting the recurrence of AF was 0.815 for the multivariate Cox regression model and 0.826 for the machine learning model by support vector machine.
Conclusion
The radiomics feature values on preprocedural cardiac CT could be helpful for predicting the recurrence of AF after PVI. Since radiomics feature analysis yields a huge number of numerical values representing the left atrial morphology in a reproducible manner, it would provide a new direction to construct a good prediction model using machine learning including artificial intelligence out of a routine cardiac CT scan.

Abstract
Abstract
Introduction
The electrical pulmonary vein (PV) isolation has been established as a curative therapy for paroxysmal atrial fibrillation (AF). Arctic Front™cryoballoon has been used worldwide for AF cryoablation. Recently, a new cryoballoon, POLARxTM CRYOABLATION system have been introduced, of which material of the balloon is softer and the N2O gas flow rate is higher.
Purpose
The aim was to investigate the procedural parameter and efficacy of POLARx comparing with Arctic Front.
Methods
This retrospective single center study included 101 consecutive patients who underwent paroxysmal AF ablation using cryoballoon at Keio University hospital from April 2021 to March 2022. The procedural data including the cryoballoon temperature and the number and duration of cryoablation were compared between POLARx (POLARx group) and ARCTIC FRONT ADVANCE PRO (AFA group). After the cryoablation, we added the radiofrequency application in order to maximize the isolated area when the voltage was remained inside PV (Figure 1). The necessities of the additional radiofrequency applications were also compared.
Results
In the present study, 64 patients in AFA group and 37 patients in POLARx group were analyzed. POLARx group included younger population and less females (62.8±9.9 vs 67.5±9.4 year of age, P=0.02; 13.5 vs 32.8%, P=0.04). There was no significant difference in comorbidities and examination data such as left atrium diameter or brain natriuretic peptide level. The minimal cryoballoon temperatures reached in POLARx group were lower than AFA group (−59.3±6.2 vs −47.7±7.5°C, P<0.01). No difference was found in the total number and duration of cryoablation and the time to isolate PV (6.1±2.1 vs 5.9±1.6, P=0.69; 790.2±256.1 vs 776.1±235.0 sec, P=0.69; 41.8±21.3 vs 47.1±29.6 sec, P=0.44, respectively). With regard to individual PVs, the total number and duration were tended to be larger at right superior PV in POLARx group (1.9±1.1 vs 1.4±0.7, P=0.01; 231.8±123.8 vs 193.2±83.0 sec, P=0.07), while there was no significant difference at the other PVs. The rate of successful PV isolation by a single cryo-application was not different between AFA and POLARx group (54.3 vs 61.4%, P=0.17). The additional radiofrequency applications were more frequent in AFA group (14.8 vs. 4.9%, P=0.003). There was a significant difference at right inferior PV (32.8 vs 8.1%, P=0.01), while not at left superior PV, left inferior PV and right superior PV (9.4 vs 2.9%, P=0.42; 9.4 vs 5.7%, P=0.71; 7.8 vs 2.7%, P=0.41). Phrenic nerve injury was occurred 1 case in both group and esophageal ulcer was occurred in 1 case in AFA group. No other complication including cardiac tamponade was occurred.
Conclusion
The total number and duration of cryoablation were not significantly different between AFA and POLARx group, except for right superior PV. There was an advantage in largely isolating right inferior PV in POLARx group comparing with AFA group.

Abstract
Abstract
Background
Atrial fibrillation (AF) patients with a history of ischaemic stroke (IS) have a higher risk for recurrent IS events and were largely excluded from the pivotal, randomised, controlled phase 3 trials on oral anticoagulants. Thus, the effectiveness and safety of edoxaban in these patients need to be studied in a real-world setting.
Purpose
To compare edoxaban real-world effectiveness and safety in AF patients with or without an IS history.
Methods
The Global ETNA-AF programme (EU: NCT02944019, Japan: UMIN000017011, South Korea/Taiwan: NCT02951039) integrates data from multiple prospective, observational, noninterventional regional studies of AF patients receiving edoxaban for stroke prevention. This snapshot analysis summarises baseline characteristics with medical history and 2-year annualised rates of all-cause death, cardiovascular (CV) death, stroke (haemorrhagic, ischaemic, any), and bleeding (including major bleeding [MB], major gastrointestinal [GI] bleeding, intracranial haemorrhage [ICH], clinically relevant nonmajor bleeding [CRNMB], and any bleeding) in patients with or without IS history.
Results
Data from 27,333 patients (3215 with prior IS and 24,118 without) from Europe, Japan, South Korea, and Taiwan were analysed. Patients with IS history were significantly older, more likely ≥75 years of age, and had a lower mean body weight and creatinine clearance (P<0.0001 for all; Table). Patients with IS history also had significantly higher baseline stroke (CHA2DS2-VASc) and bleeding (HAS-BLED) risk scores (P<0.0001 for both; Table). A significantly higher percentage of patients with IS history had previous transient ischaemic attacks (TIA), MB, and ICH (P<0.0001 for all; Table). Patients with IS history more likely received edoxaban 30 mg vs 60 mg at baseline (P<0.0001). Effectiveness and safety outcomes hazard ratios are shown in the Figure. Patients with IS history had significantly higher rates of all-cause death (4.5% vs 3.0%; P<0.0001), CV death (1.9% vs 1.4%; P=0.004), IS (2.5% vs 0.5%; P<0.0001), any stroke (3.1% vs 0.7%; P<0.0001), and TIA (0.5% vs 0.2%; P=0.0002). Patients with IS history had significantly higher annualised rates of MB (1.6% vs 1.0%; P<0.0001), major GI bleeding (0.8% vs 0.5%; P=0.003), ICH (0.6% vs 0.3%; P<0.0001), haemorrhagic stroke (0.5% vs 0.2%; P<0.0001), CRNMB (2.3% vs 1.3%; P<0.0001), and any bleeding (6.1% vs 4.1%; P<0.0001).
Conclusions
Patients with AF who have a history of IS are more likely elderly; have histories of MB, ICH, and TIA; and have high baseline stroke and bleeding risk scores. Patients with IS history receiving edoxaban have a considerably higher likelihood of experiencing IS or TIA, whereas the risk of experiencing any bleeding event (with the exception of ICH) is only modestly higher than in those without IS history.

Abstract
Abstract
Background and purpose
The All Nippon AF In the Elderly (ANAFIE) registry evaluated the current status of anticoagulant therapy in older adult patients (aged ≥75 years) with non-valvular atrial fibrillation (NVAF) in Japan. Although older adult NVAF patients requires anticoagulation therapy, some of them do not receive it and the reasons would be diverse. Therefore, we aimed to identify the phenotypes of older adult NVAF patients not treated with oral anticoagulants using data from the ANAFIE registry.
Methods
In this sub-analysis of the ANAFIE registry, the phenotypes of patients who were not receiving anticoagulants at baseline were evaluated by cluster analysis using Ward's linkage hierarchical algorithm. We used 20 categorical variables and 6 continuous variables for the cluster analysis which were used as the risk factors in the main analysis of the ANAFIE registry [1].
Results
Of 33,275 enrolled patients, 2445 (7.3%) were not receiving anticoagulants. Two clusters were identified: (1) elderly paroxysmal AF (PAF) patients with a low prevalence of comorbidities (58%) and (2) very elderly patients with a high previous major bleeding prevalence (42%). For each cluster, mean ages were 79.9 and 85.7 years, mean CHADS2 scores were 2.3 and 3.1, PAF prevalences were 83% and 54%, heart failure prevalences were 18% and 48%, the proportions of patients with a history of major bleeding were 0% and 25%, the proportions of patients with a history of catheter ablation were 21% and 8%, respectively. Annual incidence rates of each cluster were 2.62% and 9.08% for all-cause death, 1.72% and 5.83% for major adverse cardiovascular or neurological events, 1.22% and 3.14% for stroke or systemic embolism, and 0.53% and 1.43% for major bleeding.
Conclusions
In this cohort of elderly NVAF patients not receiving anticoagulants, more than half (∼60%) were PAF patients and had a low incidence of adverse outcomes. The remaining ∼40% were characterized as very elderly patients with a high prevalence of previous major bleeding and a high incidence of adverse outcomes.

Abstract
Background
Radiomics is a comprehensive analysis methodology of medical image and involves the extraction of numerous features from standard imaging. Its usefulness has been reported mainly in the field of cancer for diagnosis and prediction of prognosis. In the territory of cardiac imaging, several reports have investigated the utility of radiomics for classifying the risk of prognosis in coronary artery disease, and few practical applications have been reported for patients with atrial fibrillation (AF) who underwent catheter ablation (CA).
Purpose
The objective of this study was to evaluate the utility of radiomics analysis applying to the preprocedural cardiac computerized tomography (CT) in AF patients.
Methods
We analyzed 525 consecutive three-dimensional CT in patients with AF who underwent CA. After marking the region of interest on left atrium (LA) (including the root of pulmonary veins) semiautomatically, 107 radiomics feature values were obtained by Python program. We calculated the amount of representative statistics for each radiomics feature for prediction of persistent AF (PeAF) (Wald statistic in logistic regression analysis) and LA diameter (LAD) (coefficient correlation), respectively. To compare the distribution of the two statistics, the relative importance (calculated as the ratio of statistic to the maximum statistics among 107 radiomics features [%]) was calculated for each statistic. Further, we compared the area under the curve (AUC) in receiver operation characteristic (ROC) curve analysis for predicting PeAF between radiomics features (multivariate model) and LAD (single parameter).
Results
In 525 study patients (age 63±10 years old and male 80%), 253 (48%) were PeAF and remaining were paroxysmal AF (PAF). LAD was 43±6 mm and 38±6 mm in patients with PeAF and PAF, respectively. The relative importance of the two statistics (Wald statistic for PeAF and coefficient correlation for LAD) of 107 radiomics features are displayed in Figure 1, which shows similar distribution of two statistics. It means the close relationship between LA morphology and the form of PeAF in AF patients and the radiomics features possibly well explain the relationship. In Figure 2, the predictive capability for PeAF was compared between radiomics feature values and LAD, where the AUC was 0.85 (95% confidence interval [CI], 0.82–0.88) and 0.73 (95% CI, 0.69–0.78) for radiomics feature values and LAD, respectively (Delong test, P<0.001).
Conclusion
We applied the radiomics features for the evaluation of LA morphology. The predictive capability for PeAF in the prediction model with the radiomics feature values was much better than that with LAD alone. Since radiomics feature analysis yields a huge number of numerical values representing the LA morphology in a reproducible manner, it would provide a new direction to construct a good prediction model using machine learning including artificial intelligence out of a routine cardiac CT scan.

Abstract
Abstract
Background
Atrial fibrillation patients with a history of major bleeding (MB) are at high risk of future bleeding events; this history was an exclusion criterion in pivotal phase 3 trials of anticoagulation for stroke prevention. Real-world edoxaban effectiveness and safety in patients with a history of MB were analysed from the global ETNA programme.
Purpose
To compare edoxaban effectiveness and safety in AF patients with or without an MB history.
Methods
The Global ETNA-AF programme (EU: NCT02944019, Japan: UMIN000017011, South Korea/Taiwan: NCT02951039) integrates data from multiple prospective, observational, noninterventional regional studies of AF patients treated with edoxaban for stroke prevention. This snapshot analysis summarises global baseline characteristics and 2-year annualised rates of all-cause death, cardiovascular death, stroke (haemorrhagic, ischaemic, any), and bleeding (including MB, major gastrointestinal bleeding [MGIB], intracranial haemorrhage [ICH], clinically relevant nonmajor bleeding, and any bleeding) in patients with or without MB history.
Results
Data from 27,333 patients (479 with MB history and 26,854 without) from Europe, Japan, South Korea, and Taiwan were analysed. Patients with MB history were significantly older (P<0.0001) and more likely to be ≥75 years of age (P=0.0003), to be male (P=0.024), and to have a lower body weight and creatinine clearance (P<0.0001 for both) (Table). Globally, antiplatelet use was significantly higher in patients with MB history compared with patients without (P=0.005). Patients with MB history were more likely to have previously diagnosed heart failure (HF, P=0.001) and to receive 30 mg vs 60 mg edoxaban at baseline (P<0.0001). Hazard ratios for effectiveness and safety outcomes are shown in the Figure. Patients with MB history had significantly higher annualised rates of all-cause death (5.7% vs 3.1%; P<0.0001), ischaemic stroke (1.8% vs 0.7%; P=0.002), and any stroke (3.1% vs 0.9%; P<0.0001) than patients without MB history. Patients with MB history also had significantly higher annualised rates of MB (3.6% vs 1.0%; P<0.0001), MGIB (1.5% vs 0.5%; P=0.001), ICH (1.5% vs 0.3%; P<0.0001), fatal bleeding (0.9% vs 0.2%; P<0.0001), and fatal ICH (0.5% vs 0.1%; P=0.0002). Among patients with MB history, the annualised rate of ICH did not differ between patients with ICH history (1.42%/yr) vs without (1.65%/yr); whereas the annualised rate of MGIB was significantly higher in patients with MGIB history vs without (4.14%/yr vs 1.08%/yr; P=0.0337).
Conclusions
Patients with AF receiving edoxaban and who have a history of MB are more likely elderly, male, and have comorbidities, including HF. These patients are also more susceptible to any adverse cardiovascular event. ICH event rates were not higher in patients with prior ICH than those with non-ICH major bleedings, whereas history of MGIB was associated with a high risk of MGIB recurrence.

Abstract
Abstract
Background
Patients with Low-flow low-gradient (LFLG) aortic valve stenosis (AS) have possibly poor prognosis. Recently, it was reported that the LFLG AS patients have similar outcomes compared to high-gradient (HG) patients but worse outcomes compared to the normal-flow low-gradient [NFLG: SVi≥35 ml/m2, mPG <40mmHg] subgroup. The main determinant of LF state in severe AS patients with preserved LVEF are male gender, heart rate, LV volume and atrial fibrillation (AF). However, the relationship between the comorbidity with AF in LFLG AS and the risk of heart failure (HF) remains unclear.
Purpose
We elucidated about the prognosis of LFLG AS with AF.
Methods
We included 225 consecutive patients with severe AS (SAS, iAVA<0.6 cm2/m2) from 2013 to 2020. Among these patients, high-gradient SAS [HG-SAS; mean pressure gradient (mPG) ≥40 mmHg, n=88] and LFLG AS [stroke volume index (SVi) ≤35 ml/m2, mPG <40 mmHg, n=82] patients was extracted and the baseline characteristics including the presence or absence of AF were evaluated. The primary endpoint was worsening HF that required unplanned hospitalization or readjustment of HF drug therapy.
Results
Among patients with HG SAS and LFLG AS, worsening HF was observed in 65 patients. LFLG AS patients exhibited a higher oral rate of renin-angiotensin-system inhibitors (p=0.02). In addition, SVi and E/e' was lower in LFLG AS patients compared with HG SAS [SVi; 29.4 (24.4–34.0) versus 37.7 (28.2–45.3), p<0.0001, E/E'; 16.0 (13.1–21.5) vs 20.9 (16.0–27.4), p=0.002]. There is no differences between 2 groups in AF prevalence. Furthermore, 2 groups were subdivided as follow; HG SAS with AF (n=25), HG SAS without AF (n=63), LFLG AS with AF (n=24), LFLG AS without AF (n=58). The Kaplan Meier curves demonstrated LFLG SAS with AF experienced higher rate of worsening HF compared with HG SAS without AF and equivalent rate of worsening HF compared with HG SAS with AF (log rank, p<0.001). In the Cox hazard analysis among the LFLG AS patients, LFLG AS with paroxysmal AF (pAF, n=12) instead of chronic AF (cAF, n=12) showed a higher risk for worsening HF compared with those without AF (HR 5.0; 95% CI, 1.8–14; p=0.0028, HR 1.9; 95% CI, 0.62–5.8; p=0.26, respectively).
Conclusion
LFLG AS with AF exhibited a poor prognosis for HF compared with HG SAS without AF and equivalent rate of worsening HF compared with HG SAS with AF. Furthermore, the presence of pAf was associated with an increased risk of HF in patients with LFLF AS. Thus, intervention including drugs and catheter ablation for pAF in LFLG AS patients could lead to prevent worsening clinical outcomes.

Abstract
Bright, persistent, room-temperature phosphorescence (RTP) at long wavelengths is crucial for high-resolution imaging in the absence of in vivo autofluorescence. However, efficient long-wavelength RTP is difficult. Here, enhanced red RTP based on a unique mechanism was observed from deuterated dibenzo[g.p]chrysenes substituted with a phenoxazine. The yield was 16%, with an average lifetime of 1.8 s. An orthogonal dihedral angle between the dibenzo[g.p]chrysene and the phenoxazine in the lowest excited singlet state allowed a forbidden fluorescence to increase triplet generation. When the dihedral angle changed, disengagement of the forbidden fluorescence from the excited singlet state occurred, and the lowest triplet excited state had a facilitated phosphorescence rate without increasing its nonradiative transition rate. The facilitated phosphorescence rate as well as the large triplet yield led to the enhanced red RTP.

Abstract
Vascular dysfunction is a hallmark of chronic diseases in elderly. The contribution of the vasculature to lung repair and fibrosis is not fully understood. Here, we performed an epigenetic and transcriptional analysis of lung endothelial cells (ECs) from young and aged mice during the resolution or progression of bleomycin-induced lung fibrosis. We identified the transcription factor ETS-related gene (ERG) as putative orchestrator of lung capillary homeostasis and repair, and whose function is dysregulated in aging. ERG dysregulation is associated with reduced chromatin accessibility and maladaptive transcriptional responses to injury. Loss of endothelial ERG enhances paracrine fibroblast activation in vitro, and impairs lung fibrosis resolution in young mice in vivo. scRNA-seq of ERG deficient mouse lungs reveales transcriptional and fibrogenic abnormalities resembling those associated with aging and human lung fibrosis, including reduced number of general capillary (gCap) ECs. Our findings demonstrate that lung endothelial chromatin remodeling deteriorates with aging leading to abnormal transcription, vascular dysrepair, and persistent fibrosis following injury.

Abstract
Combined knee injuries of the anterior cruciate ligament (ACL), medial collateral ligament (MCL), and medial meniscus were called "the unhappy triad" in the past. With recent advances in diagnostic technology, combined ACL, MCL, and lateral meniscus injuries are now known to be the predominant triad. We examined and verified the treatment outcomes of the triad of combined knee injuries from both patient-based subjective evaluation and objective assessments. We studied 49 knees (49 patients) with combined injuries of the ACL, MCL, and lateral meniscus. These cases were divided into those who underwent simultaneous ACL and MCL reconstruction (group A, 18 cases) and those who underwent ACL reconstruction only because MCL injury could be treated conservatively (group B, 31 cases). Clinical evaluation was conducted preoperative and 24 months or longer after surgery. The methods included patient-reported outcomes using Short Form-36, and conventional assessments using Lysholm's score, visual analogue scale (VAS), and quantitative measurement of knee instability using Telos SE. Compared with presurgical scores, the postsurgical Short Form-36 scores showed improvements in all eight subscales, all reaching the national standard values. Significant improvements were observed in the five subscales in group A and seven subscales in group B. Furthermore, significant improvements in Lysholm's score, VAS pain score, and quantitative knee instability were achieved in both groups. This study demonstrated successful clinical outcomes in patients with a triad of knee injuries who were treated with lateral meniscus repair or partial meniscectomy and either combined MCL/ACL reconstruction or ACL reconstruction alone.

Abstract
Abstract
Due to recent advancement of DNA sequencing technologies, cancer genome analysis has shown that somatic mutations have different trends in various tissues and individuals. Some of trends has been associated with exposure of chemically reactive compounds derived from exogenous or endogenous sources and genetic deficiencies in DNA repair and DNA replication as mutational signatures. Accumulation of these information will ultimately expect to identify carcinogenic etiologies in an individual case. However, what types of DNA damage caused the mutational signatures and how extent they contribute to human carcinogenesis has not yet fully explained.To directly evaluate the chemical types of DNA damage in human colorectal tissues, we performed comprehensive identification of DNA adducts by a liquid chromatography coupled with mass spectrometry. In this DNA adductome methodology, genome DNA was enzymatically hydrolyzed into mononucleoside and separated using a reversed-phase chromatography. Chemical structure of DNA adducts including products of epigenetic modification in genome DNA was identified using column retention time and m/z of chemical standard library of DNA adducts. Peak areas of DNA adducts were normalized by that of naturally-occurring isotopologues of canonical DNA nucleoside and compared with clinicopathological information. We identified several DNA adducts in human colorectal tissue. These included DNA adducts of alkylation, oxidation, and lipid peroxidation. C5-methyl-2’-deoxycytidine was most abundant atypical DNA in human colorectal tissue and prevalent in all cases. C5-hydroxymethyl-2’-deoxycytdine was decreased in colorectal cancer cases compared with non-colorectal cancer cases. Other DNA adducts like 1,N6-etheno-2’-deoxyadenosine were present with group- or individual-specificity. Compared with our previous results of DNA adductome analysis in human stomach mucosae and kidney tissues, DNA adducts observed in human colorectal tissue showed some tissue specificity. We will discuss whether profiles of DNA adducts are based on similar contexts of chemical exposure among individuals. DNA adducts observed in our study potentially indicated chemical causes of DNA mutation in human colorectal tissue. We propose that the integration of DNA adductomics using mass spectrometric profiling with other genetic analysis such as mutational signature analysis leverage the exploration of chemical and genetic etiology in an individual carcinogenic context and evaluate gene-environment interaction in human carcinogenesis.

Abstract
OBJECTIVES We previously reported, based on a multicenter randomized-control study, that the efficacy of intra-articular injections of hyaluronic acid (IA-HA) was not inferior to that of oral non-steroidal anti-inflammatory drugs (NSAIDs) in patients with knee osteoarthritis (OA). However, the molecular effects on the pathophysiology of knee OA remain unclear. C-terminal telopeptides of type II collagen (CTX-II) is reported to primarily originate from the interface between articular cartilage and subchondral bone, which is a site of potential remodeling in OA. We performed a predefined sub-analysis of the previous study to compare the changes of urinary CTX-II (uCTX-II) in response to IA-HA to those in response to NSAID for knee OA. DESIGN A total of 200 knee OA patients were registered from 20 hospitals and randomized to receive IA-HA (2,700 kDa HA, 5 times at 1-week intervals) or NSAID (loxoprofen sodium, 180 mg/day) for 5 weeks. The uCTX-II levels were measured before and after treatment. RESULTS The uCTX-II levels were significantly increased by IA-HA treatment (337.7 ± 193.8 to 370.7 ± 234.8 ng/μmol Cr) and were significantly reduced by NSAID treatment (423.2 ± 257.6 to 370.3 ± 250.9 ng/μmol Cr). The %changes of uCTX-II induced by IA-HA (11.6 ± 29.5%) and NSAID (-9.0 ± 26.7%) was significantly different (between-group difference: 20.6, 95% confidence intervals: 10.6 to 30.6). CONCLUSIONS While both IA-HA and NSAID improved symptoms of knee OA, uCTX-II levels were increased by IA-HA and reduced by NSAIDs treatment, suggesting these treatments may improve symptoms of knee OA through different modes of action.

Background/Introduction
Once-daily edoxaban significantly reduced the risk of intracranial haemorrhage (ICH) compared with well-managed warfarin in atrial fibrillation (AF) patients in the ENGAGE AF-TIMI 48 trial. The effectiveness and safety of edoxaban in patients with prior ICH is unknown.
Purpose
To compare the effectiveness and safety of edoxaban in AF patients with or without a history of ICH.
Methods
The Global ETNA-AF programme is composed of and, thus, integrates data from multiple prospective, observational, and noninterventional regional studies collecting data of AF patients treated with edoxaban for stroke prevention. This snapshot analysis presents global and regional baseline characteristics with medical history and 2-year annualised rates of all-cause mortality, stroke (haemorrhagic, ischaemic, any), and bleeding (major bleeding [MB] including ICH, clinically relevant nonmajor bleeding [CRNMB], any bleeding), in patients with or without ICH history.
Results
Overall, 27,333 patients from Europe, Japan, South Korea, and Taiwan were analysed, including 367 with prior ICH and 26,966 without prior ICH. There were proportionally fewer patients with a history of ICH in the European population. Patients with a history of ICH were older (P=0.006), had a lower body mass index (P<0.0001), had a lower creatinine clearance (P=0.0001), and had more comorbidities, with a higher percentage of patients with a history of stroke, transient ischaemic attack (TIA), or MB (Table 1); the higher level of comorbidities noted in patients with a history of ICH was also reflected by higher baseline CHA2DS2-VASc and HAS-BLED scores (Table 1). Patients with a history of ICH were more likely receiving 30 mg edoxaban at baseline, whereas patients without ICH history were more often on 60 mg edoxaban (each P<0.0001). In patients with vs without ICH history, all-cause mortality (5.10% vs 3.14%; P=0.01), ischaemic stroke (1.79% vs 0.73%; P=0.006), and any stroke rates (3.25% vs 0.95%; P<0.0001) were higher (Table 2). Patients with vs without ICH history had higher annualised rates of MB (2.50% vs 1.00%; P=0.001), ICH (1.42% vs 0.27%; P<0.0001), haemorrhagic stroke (1.42% vs 0.20%; P<0.0001), CRNMB (2.49% vs 1.40%; P=0.04), and any bleeding (7.57% vs 4.27%; P=0.001), but these rates were low compared to other high-risk populations. ICH was not selected as a predictor of cardiovascular outcomes on multivariate prediction modelling. ICH had non-significant effects in predicting all-cause death (HR 1.22), ischemic stroke (HR 1.14), and major bleeding (HF 1.37) and repeat ICH (HR 1.94).
Conclusions
Patients with a history of ICH are a small, elderly, multimorbid subgroup of patients with AF. Treatment with the non-vitamin K antagonist oral anticoagulant edoxaban resulted in relatively low rates of major events.

Abstract
Falls (including fall on same level and fall to a lower level) are frequent medical accidents among hospitalized patients. We investigated the status of falls in our hospital, aiming to verify the usefulness of a fall risk assessment sheet and identify the risk factors of falls. 5219 patients who were admitted to the general wards of our hospital between April 2016 and March 2019 were studied. Patient background data and the result of risk assessment based on a fall risk assessment score sheet at admission were registered. The frequency and location of falls during hospitalization, and the impact on patients were investigated. Risk factors for falls were analyzed based on the assessment results at admission. 218 falls occurred during hospitalization in 152 of 5219 patients (2.9%). The most common location of falls was bedside (68%). Falls occurred at night in 28%. The impact of falls was level 1 in 18 patients, level 2 in 117, level 3a in 11, and level 3b in 6 (all had head injuries, and one had concurrent fracture). Fall rate was 1.1% (41/3791 patients) at risk level I, 6.8% (91/1335 patients) at level II, and 21.5% (20/93 patients) at level III. Multiple logistic regression analysis identified age, history of fall, tendency to act without pressing nurse call button, unstable gait, unstable when standing, and use of narcotic as risk factors of falls. The incidence of falls at our hospital was lower compared to previous reports, and fall risk assessment was useful overall.

Long-term sex differences in all-cause and infection-specific mortality post hip fracture. J Am Geriatr Soc 2022; 70:2107-2114.

Abstract
BACKGROUND Mortality rates among men are double that of women in the first 2 years after hip fracture and may be related to more infections. Research has only examined differences in short-term mortality after hip fracture. Thus, the objective was to determine if long-term all-cause mortality and infection-specific mortality rates are higher in men compared to women. METHODS Data come from a prospective cohort study (Baltimore Hip Studies 7th [BHS-7]) with up to 10.2 years of follow-up (2006-2018). The participants were selected from eight acute care hospitals in the 25-hospital BHS network. Enrolled women were frequency-matched (1:1) to men on timing of admission for hip fracture that yielded an analytic sample size of 300 participants (155 women, 145 men). Associations between sex and mortality were analyzed using Cox proportional hazard models and cause-specific Cox models adjusted for age, cognition, body mass index, pre-fracture lower extremity activities of daily living limitation, depressive symptoms, and comorbidity. RESULTS Participants had a mean age of 80 years, 48% (n = 145) were men and the median follow-up was 4.9 (interquartile range = 2.3-8.7) years. Over the follow-up period after hospital admission for hip fracture, 237 (79.0%) participants died of all causes (132 men and 105 women) and 38 (12.7%) died of infection-specific causes (25 men and 13 women). Men had significantly higher rates of all-cause mortality [hazard ratio (HR) = 2.31(95% confidence interval [CI] 2.02-2.59)] and infection-specific mortality (HR = 4.43, CI 2.07-9.51) compared to women. CONCLUSIONS Men had a two-fold higher rate of all-cause mortality and four-fold higher rate of infection-specific mortality compared to women over a follow-up period of up to 10.2 years. Findings suggest that interventions to prevent and treat infections, tailored by sex, may be needed to narrow significant differences in long-term mortality rates between men and women after hip fracture.

Abstract
BACKGROUND In monarchE, abemaciclib plus endocrine therapy (ET) as adjuvant treatment of hormone receptor-positive, human epidermal growth factor 2-negative, high risk, early breast cancer demonstrated a clinically meaningful improvement in invasive disease-free survival versus ET alone. Detailed safety analyses conducted at a median follow-up of 27 months and key patient-reported outcomes (PRO) are presented. PATIENTS AND METHODS The safety population included all patients who received at least one dose of study treatment (n=5591). Safety analyses included incidence, management, and outcomes of common and clinically relevant adverse events (AEs). Patient-reported health-related quality-of-life, ET symptoms, fatigue, and side effect burden were assessed. RESULTS The addition of abemaciclib to ET resulted in higher incidence of Grade≥3 AEs (49.7% vs 16.3% with ET alone), predominantly laboratory cytopenias (e.g., neutropenia [19.6%]) without clinical complications. Abemaciclib-treated patients experienced more serious adverse events (SAEs; 13.3% vs 7.8%). Discontinuation of abemaciclib and/or ET due to AEs occurred in 18.5% of patients, mainly due to Grade1/2 AEs (66.8%). AEs were managed with comedications (e.g., antidiarrheals), abemaciclib dose holds (61.7%), and/or dose reductions (43.4%). Diarrhea was generally low grade (Grade1/2: 77%); Grade2/3 events were highest in the first month (20.5%), most short-lived (≤7 days) and did not recur. Venous thromboembolic events (VTE) were higher with abemaciclib+ET (2.5%) vs ET (0.6%); in the abemaciclib arm, increased VTE risk was observed with tamoxifen vs AIs (4.3% vs 1.8%). PROs were similar between arms, including being 'bothered by side effects of treatment', except for diarrhea. At ≥3 months, most patients reporting diarrhea reported "a little bit" or "somewhat". CONCLUSION In patients with high risk EBC, adjuvant abemaciclib+ET has an acceptable safety profile and tolerability is supported by PRO findings. Most AEs were reversible and manageable with comedications and/or dose modifications, consistent with the known abemaciclib toxicity profile.

Abstract
BACKGROUND Recent studies reported that vascular cognitive impairment in the elderly caused by arteriosclerosis plays an important role in cognitive disorders in both vascular dementia and Alzheimer's disease. In addition, systemic metabolic disorders such as oxygen metabolism dysfunction could be risk of dementia. Based on these findings, we have developed a deep neural network-based screening test (DNN-based test) of cognitive function using basic blood test data, which allowed prediction of cognitive function expressed by Mini Mental State Examination (MMSE) scores. AIM Here, we investigated whether the DNN-based test could be applicable to assessment of the effects of exercise-diet on cognitive function. METHODS We studied the following two groups: (1) seven subjects of the local fitness gym (68.6 ± 3.2 years old). We evaluated cognitive function by the DNN-based test using blood data before and after the intervention (for 3 months). These results were compared with the measured MMSE score. (2) we studied a total of 230 subjects (67.9 ± 7.4 years old) who were members of the Tsuminory health class (Apple classroom). We assessed cognitive function by the DNN-based test before and after the intervention (for 2 months). We compared the predicted MMSE scores by the DNN-based test before and after the 2-month intervention. RESULTS In the first group, the MMSE score predicted by the DNN-based test increased from 27.1 ± 0.8 to 27.6 ± 0.7 after the intervention period (p = 0.024). The measured MMSE score also increased after exercise, but not significant (P = 0.28). In the second group, the exercise-diet therapy increased the predicted MMSE scores in 189 cases (p < 0.001). In contrast, the therapy significantly reduced the mean MMSE score (p < 0.001). DISCUSSION The MMSE score predicted by the DNN-based test were increased by exercise-diet therapy in most subjects. The DNN-based test may be useful to monitor the effect of exercise-diet therapy on cognitive function aged people.
