Geriatric nutrition risk index: a more powerful index identifying muscle mass loss in patients with rheumatoid arthritis.

OBJECTIVE: To explore the association of geriatric nutrition risk index (GNRI), a traditional albumin-body weight calculation, with myopenia in patients with rheumatoid arthritis (RA) and compare its ability to identify myopenia with protein indicators. METHODS: This cross-sectional study was carried out based on a Chinese RA cohort. Clinical data and protein indicators (including albumin, globulin, albumin to globulin ratio, prealbumin, hemoglobin) were collected. GNRI was estimated by serum albumin and body weight. Myopenia was indicated as muscle mass loss measured by bioelectric impedance analysis. RESULTS: There were 789 RA patients included with mean age 52.6 ± 12.6 years and 77.6% female. There were 41.3%, 18.0%, 27.5%, 13.2% patients with no (GNRI > 98), low (GNRI 92 to ≤ 98), moderate (GNRI 82 to < 92), and major nutrition-related risk (GNRI < 82). There were 406 (51.5%) RA patients with myopenia, RA patients with major nutrition-related risk had the highest prevalence of myopenia (87.5% vs. 73.3% vs. 50.0% vs. 26.1%). Multivariate logistic analysis showed that compared with no risk, RA patients with low (OR = 3.23, 95% CI: 1.86-5.61), moderate (OR = 9.56, 95% CI: 5.70-16.01), and major nutrition-related risk (OR = 28.91, 95% CI: 13.54-61.71) were associated with higher prevalence of myopenia. Receiver operating characteristic curves showed that GNRI (AUC = 0.79) performed a better identifiable ability toward myopenia than serum albumin (AUC = 0.66) or others indicators (AUC range 0.59 to 0.65), respectively. CONCLUSION: GNRI, an objective and convenient albumin-weight index, may be preferable for identifying myopenia in RA patients. Key Points • We firstly elucidated the association of GNRI with muscle mass loss among RA patients, and compared its ability to identify muscle mass loss with serum albumin or other protein indicators. • Major nutrition-related risk identified by GNRI showed the highest risk of muscle mass loss, GNRI demonstrated a greater ability to identify myopenia in RA patients. which indicated GNRI was an objective and convenient albumin-weight index to identify myopenia in RA patients.

Pro-ferroptotic signaling promotes arterial aging via vascular smooth muscle cell senescence.

Senescence of vascular smooth muscle cells (VSMCs) contributes to aging-related cardiovascular diseases by promoting arterial remodelling and stiffness. Ferroptosis is a novel type of regulated cell death associated with lipid oxidation. Here, we show that pro-ferroptosis signaling drives VSMCs senescence to accelerate vascular NAD+ loss, remodelling and aging. Pro-ferroptotic signaling is triggered in senescent VSMCs and arteries of aged mice. Furthermore, the activation of pro-ferroptotic signaling in VSMCs not only induces NAD+ loss and senescence but also promotes the release of a pro-senescent secretome. Pharmacological or genetic inhibition of pro-ferroptosis signaling, ameliorates VSMCs senescence, reduces vascular stiffness and retards the progression of abdominal aortic aneurysm in mice. Mechanistically, we revealed that inhibition of pro-ferroptotic signaling facilitates the nuclear-cytoplasmic shuttling of proliferator-activated receptor-γ and, thereby impeding nuclear receptor coactivator 4-ferrtin complex-centric ferritinophagy. Finally, the activated pro-ferroptotic signaling correlates with arterial stiffness in a human proof-of-concept study. These findings have significant implications for future therapeutic strategies aiming to eliminate vascular ferroptosis in senescence- or aging-associated cardiovascular diseases.

Resveratrol prevents age-related heart impairment through inhibiting the Notch/NF-κB pathway.

Resveratrol (RSV) is a natural polyphenol compound found in various plants that has been shown to have potential benefits for preventing aging and supporting cardiovascular health. However, the specific signal pathway by which RSV protects the aging heart is not yet well understood. This study aimed to explore the protective effects of RSV against age-related heart injury and investigate the underlying mechanisms using a D-galactose-induced aging model. The results of the study indicated that RSV provided protection against age-related heart impairment in mice. This was evidenced by the reduction of cardiac histopathological changes as well as the attenuation of apoptosis. RSV-induced cardioprotection was linked to a significant increase in antioxidant activity and mitochondrial transmembrane potential, as well as a reduction in oxidative damage. Additionally, RSV inhibited the production of pro-inflammatory cytokines such as interleukin-1ß (IL-1ß) and tumor necrosis factor-α (TNF-α). Furthermore, the expression of toll-like receptor 4 (TLR4), nuclear factor kappa-B p65 (NF-κB p65), and notch 1 protein were inhibited by RSV, indicating that inhibiting the Notch/NF-κB pathway played a critical role in RSV-triggered heart protection in aging mice. Moreover, further data on intestinal function demonstrated that RSV significantly increased short-chain fatty acids (SCFAs) in intestinal contents and reduced the pH value in the feces of aging mice. RSV alleviated aging-induced cardiac dysfunction through the suppression of oxidative stress and inflammation via the Notch/NF-κB pathway in heart tissue. Furthermore, this therapeutic effect was found to be associated with its protective roles in the intestine.

Comparisons of drug-eluting balloon versus drug-eluting stent for the treatment of cancer patients presenting with acute myocardial infarction.

BACKGROUND: Treatment for cancer patients presenting with acute myocardial infarction (AMI) remains challenging. The objective of the study was to investigate the safety and efficiency of drug eluting balloon (DEB) versus drug eluting stent (DES) in this high-risk group. METHODS: Between 1st January 2017 and 1st January 2022, cancer patients admitted to Beijing Chaoyang Hospital with AMI were retrospectively enrolled. The primary endpoint was major adverse cardiovascular event (MACE). The secondary endpoints included major bleeding events, heart failure and cardiac complications. RESULTS: A total of 164 cancer patients presenting with AMI were included in the final analysis. Patients treated with DEB had a numerically lower rate of MACE than those treated with DES during a median follow-up of 21.8 months (22.9% vs. 37.1%, p = 0.23). Patients treated with DEB had a trend towards lower rate of major bleeding events than patients treated with DES (6.3% vs. 18.1%, HR 2.96, 95% CI [0.88, 9.92], p = 0.08). There were no significant differences between the two groups with regards to the rate of heart failure (4.2% vs. 9.5%, p = 0.32) and cardiac complications (0.0% vs. 2.6%, p = 0.56). CONCLUSIONS: The present study demonstrated that in cancer patients with AMI, DEB had a trend towards lower rate of major bleeding events and a numerically lower rate of MACE compared with DES.

Comparisons of different new-generation transcatheter aortic valve implantation devices for patients with severe aortic stenosis: a systematic review and network meta-analysis.

BACKGROUND: Whether there are differences among the new-generation transcatheter aortic valve implantation (TAVI) devices for patients with aortic stenosis remains unclear. The aim of the study was to compare the efficiency and safety of different new-generation TAVI devices for patients with aortic stenosis. MATERIALS AND METHODS: A comprehensive search of PubMed, Embase and Web of Science from their inception to 1 February 2022. Randomized clinical trials and observational studies that compared two or more different TAVI devices were enroled. Pairwise meta-analysis and frequentist network meta-analysis were conducted to pool the outcome estimates of interest. RESULTS: A total of 79 studies were finally included. According to the surface under the cumulative ranking, the top two ranked valves for lower rates of events were as follows: direct flow medical (DFM) (4.6%) and Lotus (48.8%) for lower rate of device success; Sapien 3 (16.8%) and DFM (19.7%) for lower mortality; DFM (8.6%) and Sapien 3 (25.5%) for lower rates of stroke; Evolut (27.6%) and DFM (35.8%) for lower rates of major and life-threatening bleeding; Portico (22.6%) and Sapien 3 (41.9%) for lower rates of acute kidney injury; Acurate (8.6%) and DFM (13.2%) for lower rates of permanent pacemaker implantation; Lotus (0.3%) and Sapien 3 (22.7%) for lower rates of paravalvular leak; Evolut (1.4%) and Portico (29.1%) for lower rates of mean aortic valve gradients. CONCLUSIONS: The findings of the present study suggested that the device success rates were comparable among these new-generation valves except for DFM. After excluding DFM, Sapien 3 might be the best effective for decreased mortality and stroke; Lotus might be the best effective for decreased paravalvular leak; Evolut might be the best effective for decreased major and life-threatening bleeding and mean aortic valve gradients; Acurate and Portico might be the best effective for decreased permanent pacemaker implantation and acute kidney injury, respectively.

[Distribution Characteristics, Ecological Risks, and Source Identification of Heavy Metals in Cultivated Land Under Non-grain Production].

The purpose of this study was to explore the distribution characteristics and potential ecological risks of soil heavy metal pollution of cultivated land under non-grain production. Taking a typical area around Hangzhou Bay as an example, 254 topsoil samples (0-20 cm) of cultivated land were collected, and the content of eight soil heavy metals in four different cultivated land use types, including grain, seedlings, vegetables, and fruits, was analyzed. The ecological risk was assessed by the Nemerow pollution index and the potential ecological risk index, and the PMF model was used to identify the source of soil heavy metals in the study area. The results showed that the average contents of As, Cr, Cd, Cu, Hg, Ni, and Zn were all higher than the soil background value, except for Pb, but were lower than the national risk control standard for soil contamination of agricultural land. Non-grain production had a significant impact on the accumulation of heavy metals in soil. The content of heavy metals in nurseries and orchards was relatively high, followed by vegetable fields, and the lowest in grain fields. The Nemerow index showed that the cultivated land in the study area was in a light pollution level as a whole, and the single-factor pollution risks of Hg, Cd, and As were relatively high. The potential ecological risk levels of heavy metals in different cultivated land use types were:nurseries>orchards>vegetable fields>grain fields. The PMF results showed that the main sources of soil heavy metals in the study area were mixed sources of industrial emissions (36.8%), natural parent material sources (28.4%), atmospheric deposition sources (21.4%), and agricultural activity sources (13.4%). In conclusion, the increase in the application of chemical fertilizers and pesticides was the direct reason for the increase in soil heavy metal content caused by non-grain production of the cultivated land, whereas the industrial and mining emissions and atmospheric deposition accelerated the increase in soil heavy metal content in the study area.

A Novel Reperfusion Strategy for Primary Percutaneous Coronary Intervention in Patients with Acute ST-Segment Elevation Myocardial Infarction: A Prospective Case Series.

BACKGROUND: Ischemia reperfusion injury (IRI) remains a major problem in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). We have developed a novel reperfusion strategy for PCI and named it "volume-controlled reperfusion (VCR)". The aim of the current study was to assess the safety and feasibility of VCR in patients with STEMI. METHODS: Consecutive patients admitted to Beijing Chaoyang Hospital with STEMI were prospectively enrolled. The feasibility endpoint was procedural success. The safety endpoints included death from all causes, major vascular complications, and major adverse cardiac event (MACE), i.e., a composite of cardiac death, myocardial reinfarction, target vessel revascularization (TVR), and heart failure. RESULTS: A total of 30 patients were finally included. Procedural success was achieved in 28 (93.3%) patients. No patients died during the study and no major vascular complications or MACE occurred during hospitalization. With the exception of one patient (3.3%) who underwent TVR three months after discharge, no patient encountered death (0.0%), major vascular complications (0.0%), or and other MACEs (0.0%) during the median follow-up of 16 months. CONCLUSION: The findings of the pilot study suggest that VCR has favorable feasibility and safety in patients with STEMI. Further larger randomized trials are required to evaluate the effectiveness of VCR in STEMI patients.

Polysaccharides as antioxidants and prooxidants in managing the double-edged sword of reactive oxygen species.

Polysaccharides, a class of naturally occurring carbohydrates, were widely presented in animals, plants, and microorganisms. Recently, health benefits of polysaccharides have attracted much attention due to their unique characteristics in reactive oxygen species (ROS) management. ROS, by-products of aerobic metabolism linked to food consumption, exhibited a dual role in protecting cells and fostering pathogenesis collectively termed double-edged sword. Some interesting studies reported that polysaccharides could behave as prooxidants under certain conditions, besides antioxidant capacities. Potentiation of the bright side of ROS could contribute to the host defense that was vitally important for the polysaccharides acting as biological response modifiers. Correspondingly, disease prevention of polysaccharides linked to the management of ROS production was systematically described and discussed in this review. Furthermore, major challenges and future prospects were presented, aiming to provide new insight into applying polysaccharides as functional food ingredients and medicine.

Comparisons of Drug-Eluting Balloon versus Drug-Eluting Stent in the Treatment of Young Patients with Acute Myocardial Infarction.

BACKGROUND: The incidence of acute myocardial infarction (AMI) in the younger population has been increasing gradually in recent years. The objective of the present study is to investigate the safety and effectiveness of drug-eluting balloons (DEBs) in young patients with AMI. METHODS: All consecutive patients with AMI aged ≤ 45 years were retrospectively enrolled. The primary endpoint was a device-oriented composite endpoint (DOCE) of cardiac death, target vessel myocardial infarction (MI), or target lesion revascularization (TLR). The secondary study endpoints included heart failure and major bleeding events. RESULTS: A total of 276 young patients presenting with AMI were finally included. The median follow-up period was 1155 days. Patients treated with DEBs had a trend toward a lower incidence of DOCEs (3.0% vs. 11.0%, p = 0.12) mainly driven by the need for TLR (3.0% vs. 9.1%, p = 0.19) than those treated with DESs. No significant differences between the two groups were detected in the occurrence of cardiac death (0.0% vs. 0.5%, p = 0.69), MI (0.0% vs. 1.4%, p = 0.40), heart failure (0.0% vs. 1.9%, p = 0.39), or major bleeding events (1.5% vs 4.8%, p = 0.30). Multivariate regression analysis showed that DEBs were associated with a trend toward a lower risk of DOCEs (HR 0.13, 95% CI [0.02, 1.05], p = 0.06). CONCLUSIONS: The findings of the present study suggested that DEBs might be a potential treatment option in young patients with AMI. A larger scale, randomized, multicenter study is required to investigate the safety and effectiveness of DEBs in this setting.

LncRNA FGF7-5 and lncRNA GLRX3 together inhibits the formation of carotid plaque via regulating the miR-2681-5p/ERCC4 axis in atherosclerosis.

Atherosclerotic plaques belong to the common vascular disease in the aged, which rupture will lead to acute thromboembolic diseases, the leading cause of fatal cardiovascular events. Accumulating evidence indicates that the lncRNAs-miRNAs-mRNA regulatory network plays a critical role in atherosclerosis. Based on RNA sequencing (GSE207252), we constructed expression profiles of lncRNAs, microRNAs, and mRNA in the carotid plaque of atherosclerosis patients and analyzed differentially expressed genes (DEGs). We identified three candidate lncRNAs using two algorithms (LASSO and SVM-RFE): lnc_GLRX3, lnc_FGF7-5, and DISC1FP1). LNCipedia, TargetScan, and miRDB databases were used to predict target miRNAs of lncRNAs and target genes of miRNAs. Gene ontology (GO) functional annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and Gene Set Enrichment Analysis (GSEA) analysis of DEGs was carried out using the R package clusterProfiler. A PPI network was constructed using the STRING website and visualized by Cytoscape. According to the "MCC" method of the plug-in cytoHubba in Cytoscape, ERCC4 was the top hub gene of the PPI network. We constructed a lncRNA_FGF7-5/lncRNA_GLRX3-miR-2681-5p-ERCC4 regulatory network for carotid plaque using lncRNA-miRNA and miRNA-mRNA pairs. Next, lncRNA_FGF7-5 and lncRNA_GLRX3 targeted miR-2681-5p directly to upregulate ERCC4 expression. Silencing of lncRNA_FGF7-5 and lncRNA_GLRX3 promoted apoptosis and TP53 expression in HUVECs treated with ox-LDL; however, these effects were reversed by ERCC4-overexpression. Taken together, these findings indicated that lncRNA_FGF7-5 and lncRNA_GLRX3 together reduced atherosclerosis-induced apoptosis of HUVECs via targeting miR-2681-5p to increase ERCC4 expression, thereby preventing the formation of carotid plaque and finally inhibiting atherosclerosis progression.

Activity fingerprinting of polysaccharides on oral, gut, pancreas and lung microbiota in diabetic rats.

The modern rise in type 2 diabetes mellitus (T2DM) and its correlation to commensal microbiota have elicited global concern about the patterns of microbial action in the host. With the exception of that linked to gut, microbiota were also colonized in pancreas, oral, and lung, contributing to the physiopathology of T2DM. In this study, we aimed to explore the protective effects of Ganoderma atrum polysaccharide (PSG) and White Hyacinth Bean polysaccharide (WHBP) on the intestine, pancreas, oral, and lung microbiota in T2DM rats. Here we showed that, despite capacities of polysaccharides that exerted similar protective effects on hyperglycemia, dyslipidemia, insulin resistance and dysbacteriosis in T2DM rats, PSG and WHBP were able to be characterized by their own "target" bacteria, which could be proposed for activity-fingerprinting of polysaccharide species. Furthermore, we found a mutual bacteria spectrum in the pancreas and lung, and most bacteria could be tracked to oral or gut samples. Notably, the overlapping areas of the microbiota profile between organs (pancreas, lung) and saliva were more than in the gut, suggesting that a saliva sample was also of interest to serve as a "telltale sign" for judging pancreatic injury. Together, these microbiota interactions provided a new potential to harvest alternative samples for disease surveillance. Meanwhile, polysaccharides had anti-T2DM abilities, which could be distinguished by their own characteristic bacteria.

Holistic review and meta-analysis of independent impact of the residual SYNTAX score on prognosis in patients with acute coronary syndrome.

Objectives. The appropriate extent of revascularization following primary intervention is unknown. We conducted a systematic review and meta-analysis of residual Syntax score (rSS) to predict the outcomes and provide guide to optimal management of revascularization following primary intervention. Designs. Previously published studies from 2007 to 2020 assessing the prognostic impact of rSS after ACS were included for this meta-analysis. The primary endpoint was defined as the major adverse clinical events (MACE) in multivariable analysis. The risk ratios (RRs) with 95% confidence intervals (CI) were calculated using the RevMan 5.4 software. Results. A total of 8,157 participants complicated with ACS from 12 clinical studies were included in this analysis. Based on the wide range of rSS studies available, we classified it into two major groups: rSS < 8 and rSS ≥ 8. In multivariate analysis, the rSS was an independent risk marker for MACE [RR = 1.04 (95%CI; 1.00-1.08)], all-cause mortality [RR = 1.05 (1.03-1.07)] and cardiovascular death [RR = 1.05 (1.03-1.07)]. Patients with incomplete revascularization (ICR) showed higher prevalence of MACE along with all-cause mortality, cardiovascular morality, and recurrent myocardial infarction without significant heterogeneity [RR = 1.60 (1.03-1.07), 2.30 (1.57-3.38), 3.57 (2.09-6.10) and 1.70 (1.38-2.09), respectively]. The patients with rSS ≥ 8 presented higher frequency of all-cause mortality [RR = 2.99 (2.18-4.09)], cardiovascular death [RR = 3.32 (2.22-4.95)], and recurrent myocardial infarction [RR = 1.64 (1.34-2.02)]. Conclusion. The meta-analysis indicated that an rSS value of 8 could be a reasonable cut-off for incomplete revascularization after ACS and is an efficient tool to guide revascularization. In future, detailed research should focus on investigation of the optimal value of the rSS score.

The Impact of Cardiac Dysfunction Based on Killip Classification on Gastrointestinal Bleeding in Acute Myocardial Infarction.

Background: Owing to limited data, the effect of cardiac dysfunction categorized according to the Killip classification on gastrointestinal bleeding (GIB) in patients with acute myocardial infarction (AMI) is unclear. The present study aimed to investigate the impact of cardiac dysfunction on GIB in patients with AMI and to determine if patients in the higher Killip classes are more prone to it. Methods: This retrospective study was comprised of patients with AMI who were admitted to the cardiac intensive care unit in the Heart Center of the Beijing Chaoyang Hospital between December 2010 and June 2019. The in-hospital clinical data of the patients were collected. Both GIB and cardiac function, according to the Killip classification system, were confirmed using the discharge diagnosis of the International Classification of Diseases, Tenth Revision coding system. Univariate and multivariate conditional logistic regression models were constructed to test the association between GIB and the four Killip cardiac function classes. Results: In total, 6,458 patients with AMI were analyzed, and GIB was diagnosed in 131 patients (2.03%). The multivariate logistic regression analysis showed that the risk of GIB was significantly correlated with the cardiac dysfunction [compared with the Killip class 1, Killip class 2's odds ratio (OR) = 1.15, 95% confidence interval (CI): 0.73-1.08; Killip class 3's OR = 2.63, 95% CI: 1.44-4.81; and Killip class 4's OR = 4.33, 95% CI: 2.34-8.06]. Conclusion: This study demonstrates that the degree of cardiac dysfunction in patients with acute myocardial infarction is closely linked with GIB. The higher Killip classes are associated with an increased risk of developing GIB.

Association Between Metabolic Dysfunction-Associated Fatty Liver Disease and Cardiovascular Risk in Patients With Rheumatoid Arthritis: A Cross-Sectional Study of Chinese Cohort.

Background: The nomenclature from non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MAFLD) is considered to identify more cardiovascular disease (CVD) risks in the general population. Patients with rheumatoid arthritis (RA) carry an excess risk for CVD. However, the prevalence of MAFLD and its relationship with CVD risks in RA have not been reported. Methods: This cross-sectional study retrospectively analyzed clinical data from a Chinese RA cohort. MAFLD was diagnosed according to the criteria proposed by an international expert panel from 22 countries in 2020. CVD risk in patients with RA was estimated by the Prediction for Atherosclerotic Cardiovascular Disease Risk in China with a 1.5 multiplication factor. Results: Among 513 included patients with RA, 78.4% were women and the mean ± SD age was 51.8 ± 12.6 years. The prevalence of MAFLD was 21.4%. There were 10.9% patients with RA concomitated with CVD events and 32.4% with a high-estimated 10-year CVD risk. Besides a higher liver fibrosis score and a higher ratio of advanced fibrosis, RA patients with MAFLD had a higher rate of CVD events (17.3 vs. 9.2%) and a higher proportion of high estimated 10-year CVD risk (55.5 vs. 26.1%) than those without. Multivariate logistic regression analysis showed that MAFLD was associated with an increase in CVD events [adjusted odds ratio (AOR) = 2.190, 95% CI 1.135-4.227] and high estimated 10-year CVD risk (AOR = 2.483, 95% CI 1.412-4.365, all p < 0.05). Conclusion: Metabolic dysfunction-associated fatty liver disease was associated with increased CVD risk in patients with RA, which implies the importance of early detection and management of MAFLD in patients with RA.

LSD1 downregulates p21 expression in vascular smooth muscle cells and promotes neointima formation.

Neointima formation is characterized by the proliferation of vascular smooth muscle cells (VSMC). Although lysine-specific demethylase 1 (LSD1) has critical functions in several diseases, its role in neointima formation remains to be clarified. In this study, we aimed to explore the crucial role of LSD1 on neointima formation using a carotid artery injury model in mice. We observed that aberrant LSD1 expression was increased in human and mouse stenotic arteries and platelet-derived growth factor-BB (PDGF-BB)-treated VSMC. Furthermore, LSD1 knockdown significantly mitigated neointima formation in vivo and inhibited PDGF-BB-induced VSMC proliferation in vitro. We further uncovered that LSD1 overexpression exhibited opposite phenotypes in vivo and in vitro. Finally, LSD1 knockdown inhibited VSMC proliferation by increasing p21 expression, which is associated with LSD1 mediated di-methylated histone H3 on lysine 4 (H3K4me2) modification. Taken together, our data suggest that LSD1 may be a potential therapeutic target for the treatment of neointima formation.

Targeting the forkhead box protein P1 pathway as a novel therapeutic approach for cardiovascular diseases.

Cardiovascular disease (CVD) is the leading cause of death worldwide and encompasses diverse diseases of the vasculature, myocardium, cardiac electrical circuit, and cardiac development. Forkhead box protein P1 (Foxp1) is a large multi-domain transcriptional regulator belonging to the Fox family with winged helix DNA-binding protein, which plays critical roles in cardiovascular homeostasis and disorders. The broad distribution of Foxp1 and alternative splicing isoforms implicate its distinct functions in diverse cardiac and vascular cells and tissue types. Foxp1 is essential for diverse biological processes and has been shown to regulate cellular proliferation, apoptosis, oxidative stress, fibrosis, angiogenesis, cardiovascular remodeling, and dysfunction. Notably, both loss-of-function and gain-of-function approaches have defined critical roles of Foxp1 in CVD. Genetic deletion of Foxp1 results in pathological cardiac remodeling, exacerbation of atherosclerotic lesion formation, prolonged occlusive thrombus formation, severe cardiac defects, and embryo death. In contrast, activation of Foxp1 performs a wide range of physiological effects, including cell growth, hypertrophy, differentiation, angiogenesis, and cardiac development. More importantly, Foxp1 exerts anti-inflammatory and anti-atherosclerotic effects in controlling coronary thrombus formation and myocardial infarction (MI). Thus, targeting for Foxp1 signaling has emerged as a pre-warning biomarker and a novel therapeutic approach against progression of CVD, and an increased understanding of cardiovascular actions of the Foxp1 signaling will help to develop effective interventions. In this review, we focus on the diverse actions and underlying mechanisms of Foxp1 highlighting its roles in CVD, including heart failure, MI, atherosclerosis, congenital heart defects, and atrial fibrillation.

Prognostic value of cardiac inflammation in ST-segment elevation myocardial infarction: A 18F-fluorodeoxyglucose PET/CT study.

BACKGROUND: 18F-fluorodeoxyglucose (FDG) imaging is used to detect cardiac inflammation and predict functional outcome in acute myocardial infarction (MI). However, data on the correlation of post-MI acute cardiac inflammation evaluated by 18F-FDG imaging and major adverse cardiac events (MACE) are limited. Therefore, we sought to explore the prognostic value of cardiac 18F-FDG imaging in patients with acute ST-segment elevation MI (STEMI). METHODS: Thirty-six patients with STEMI underwent 18F-FDG positron emission tomography/computed tomography (PET/CT) 5 days after primary percutaneous coronary intervention. 18F-FDG activity in infarcted and remote regions, as well as peri-coronary adipose tissue (PCAT), were measured and expressed as the maximum standardized uptake value (SUVmax). Patients were followed to determine the occurrence of MACE. RESULTS: The infarcted myocardium had a higher 18F-FDG intensity than the remote area. Moreover, the PCAT of culprit coronary arteries showed a higher 18F-FDG uptake than that of non-culprit arteries. Multivariate Cox regression analysis showed that increased SUVmax of PCAT [HR 5.198; 95% CI (1.058, 25.537), P = .042] was independently associated with a higher risk of MACE. CONCLUSIONS: Enhanced PCAT activity after acute MI is related to the occurrence of MACE, and 18F-FDG PET/CT plays a promising role in providing prognostic information in patients with STEMI.

Addition of Fibroblast-Stromal Cell Markers to Immune Synovium Pathotypes Better Predicts Radiographic Progression at 1 Year in Active Rheumatoid Arthritis.

Objectives: This study aims to investigate if addition of fibroblast-stromal cell markers to a classification of synovial pathotypes improves their predictive value on clinical outcomes in rheumatoid arthritis (RA). Methods: Active RA patients with a knee needle synovial biopsy at baseline and finished 1-year follow-up were recruited from a real-world prospective cohort. Positive staining for CD20, CD38, CD3, CD68, CD31, and CD90 were scored semiquantitatively (0-4). The primary outcome was radiographic progression defined as a minimum increase of 0.5 units of the modified total Sharp score from baseline to 1 year. Results: Among 150 recruited RA patients, 123 (82%) had qualified synovial tissue. Higher scores of CD20+ B cells, sublining CD68+ macrophages, CD31+ endothelial cells, and CD90+ fibroblasts were associated with less decrease in disease activity and greater increase in radiographic progression. A new fibroblast-based classification of synovial pathotypes giving more priority to myeloid and stromal cells classified samples as myeloid-stromal (57.7%, 71/123), lymphoid (31.7%, 39/123), and paucicellular pathotypes (10.6%, 13/123). RA patients with myeloid-stromal pathotype showed the highest rate of radiographic progression (43.7% vs. 23.1% vs. 7.7%, p = 0.011), together with the lowest rate of Boolean remission at 3, 6, and 12 months. Baseline synovial myeloid-stromal pathotype independently predicted radiographic progression at 1 year (adjusted OR: 3.199, 95% confidence interval (95% CI): 1.278, 8.010). Similar results were obtained in a subgroup analysis of treatment-naive RA. Conclusions: This novel fibroblast-based myeloid-stromal pathotype could predict radiographic progression at 1 year in active RA patients which may contribute to the shift of therapeutic decision in RA.

Impact of Prior Digestive System Disease on In-Hospital Gastrointestinal Bleeding in Patients with Acute Myocardial Infarction.

OBJECTIVE: Patients presenting with acute myocardial infarction (AMI) with prior digestive system disease are more likely to suffer from gastrointestinal (GI) bleeding than those without these diseases. However, few articles reported how the different conditions of the digestive tract produced different risks of GI bleeding. METHODS: A single-center study on 7464 patients admitted for AMI from December 2010 to June 2019 in the Beijing Chaoyang Heart Center was retrospectively examined. Patients with major GI bleeding (n = 165) were compared with patients without (n = 7299). Univariate and multivariate logistic regression models were constructed to test the association between GI bleeding and prior diseases of the digestive tract, including gastroesophageal reflux disease, chronic gastritis, peptic ulcer, hepatic function damage, diseases of the colon and rectum, and gastroenterological tract tumors. RESULTS: Of the 7464 patients (mean age, 63.4; women, 25.6%; STEMI, 58.6%), 165 (2.2%) experienced major GI bleeding, and 1816 (24.3%) had a history of digestive system disease. The risk of GI bleeding was significantly associated with peptic ulcer (OR = 4.19, 95% CI: 1.86-9.45) and gastroenterological tumor (OR = 2.74, 95% CI: 1.07-7.04), indicated by multivariate logistic regression analysis. CONCLUSION: Preexisting peptic ulcers and gastroenterological tract tumors rather than other digestive system diseases were indicators of gastrointestinal bleeding in patients with AMI who undergo standard antithrombotic treatment during hospitalization.
