Abstract
The objective of this study was to establish an animal model of arteriosclerosis for assessing vasospasm and to investigate the relationship between arteriosclerosis and vasospasm. Twelve-week-old male Sprague-Dawley rats were fed a diet supplemented with adenine and vitamin D (adenine/vitD). Body weight, blood, and femoral artery histopathology were assessed at 2, 4, and 6 weeks. Change in the femoral artery was examined by transmission electron microscope (TEM). Vasospasm was induced by administering epinephrine extravascularly into the femoral artery and released by the treatment with lidocaine as a vasodilator. During this period, the extravascular diameter and blood flow were measured. The rats in the adenine/vitD group developed renal dysfunction, uremia, hyperphosphatemia, and elevated serum alkaline phosphatase. Histological and TEM analyses of the femoral arteries in the treated rats revealed the degeneration of elastic fibers and extensive calcification of the tunica media and intima. Vascular smooth muscles were degenerated and osteoblasts were developed, resulting in calcified arteriosclerosis. Vasospasm in arteriosclerotic arteries was detected; however, vasodilation as well as an increase in the blood flow was not observed. This study revealed the development of vasospasm in the femoral arteries of the arteriosclerotic rats and, a conventional vasodilator did not release the vasospasm.

Abstract
BACKGROUND Epidemiological studies have identified smoking as an independent risk factor for development of chronic kidney disease. However, the early renal pathological lesions have not been clearly elucidated. METHODS We investigated time-zero biopsy specimens from 547 living kidney donors and evaluated the relationships between smoking and renal histological changes, including arteriolar hyalinization, intimal thickening of small-medium arteries, global glomerulosclerosis, and interstitial fibrosis and tubular atrophy (IF/TA). RESULTS A total of 199 subjects (36.4%) had smoking history; 92 (16.8%) and 107 (19.6%) subjects had <20 pack-years and ≥20 pack-years of smoking, respectively. Cumulative smoking dose was significantly associated with prevalence of arteriolar hyalinization: the multivariable-adjusted odds ratio (OR) per 20 pack-year increase was 1.50 (95% confidence interval 1.15-1.97). The ORs for smokers with <20 pack-years and ≥20 pack-years versus never-smokers were 1.76 (1.01-3.09) and 2.56 (1.48-4.44), respectively. Smoking was also associated with prevalence of >10% global glomerulosclerosis: the OR per 20 pack-year increase was 1.24 (0.96-1.59). The ORs for smokers with <20 pack-years and ≥20 pack-years versus never-smokers were 1.50 (0.98-2.78) and 2.11 (1.18-3.79), respectively. The ORs for these pathological changes increased significantly depending on cumulative smoking dose. Intimal thickening of small-medium arteries and IF/TA were not associated with smoking status. The prevalence of arteriolar hyalinization remained higher in patients with ≥10 years since smoking cessation than in never-smokers [OR 2.23 (1.03-4.83)]. CONCLUSIONS Subclinical pathological injury caused by smoking is potentially associated with renal arteriolar hyalinization and glomerular ischaemia.

Abstract
Aortic dissection (AD) is a critical cardiovascular condition with the potential for devastating consequences. This study evaluated the histological changes in the aorta wall in patients with AD and aortic aneurysm (AA) who received surgical aortic replacement. Histopathological data showed that modifications of the media layer (p = 0.0197), myxomatous aspect (p = 0.0001), and subendothelial layer degeneration (p = 0.0107) were more frequently seen in AA versus AD samples. Patients with AA were approximately twice as likely to develop histological changes than those with AD (p = 0.0037). Patients with moderate or severe medial degeneration had a higher chance of developing AD (p = 0.0001). Because the histopathological score proved to be a predictor of both in-hospital and overall mortality, its evaluation should become the standard of care in any patients who undergo aortic replacement. Individualized postoperative management might be influenced by the histopathological aspect of the aortic layer.

Abstract
PURPOSE Curative surgical treatment of biliary tract cancer is highly invasive and involves postoperative complications. Abdominal aortic calcification is a parameter that is reportedly linked to systemic arteriosclerosis. We measured the abdominal aortic calcification volume (AACV), assessed the correlation between AACV and postoperative complications, and evaluated the clinical utility of AACV. METHODS We retrospectively evaluated 97 patients (ampullary carcinoma, n = 21; distal bile duct cancer, n = 43; hilar bile duct cancer, n = 33). We assessed the calcification volume of the abdominal aorta from the renal artery ramification to the common iliac artery bifurcation. The correlation between AACV, clinical factors, and postoperative complications was evaluated. RESULTS The average AACV was 5.02 cm3, and the median AACV was 3.74 (range 0-27.4) cm3. The AACV was significantly related to age (P = 0.009), Brinkman index (P = 0.007), and history of cardiovascular disease (P = 0.015). The AACV was strongly correlated with postoperative complications (P < 0.001) and Clavien-Dindo grade > III postoperative complications (P < 0.001). The AACV was also correlated with pancreatic fistula in pancreatectomy cases (P < 0.001). A multivariate analysis revealed that the AACV was an independent predictor of postoperative complications. CONCLUSION The AACV was significantly associated with postoperative complications. The AACV could be used for the preoperative assessment of surgical risk.

Abstract
BACKGROUND Platelets play an important role in the pathogenesis of inflammatory and proliferative vascular changes. The aim of this study was to investigate whether human platelets are able to induce transplant arteriosclerosis in a humanized C57/Bl6-Rag2-/-γc-/- mouse xenograft model. METHODS Nonactivated and in vitro-activated human platelets were analyzed and phenotyped for surface markers by flow cytometry. Side branches of human mammary arteries were implanted into the infrarenal aorta of recipients, followed by daily application of human platelets and histological analyzed on day 30 after transplantation. RESULTS Human platelets collected by apheresis had low levels of platelet activation markers. However, after in vitro activation, expression was markedly increased. Sixty minutes after injection in recipient mice, nonactivated human platelets become significantly activated. Increased adhesion of platelets to the vascular endothelium was detected by in vivo fluorescence microscopy. After intravenous injection of nonactivated or activated platelets, human xenografts showed pronounced intimal proliferation. Immunohistological analysis showed that the group treated with activated human platelets exhibited significantly increased intragraft protein expression of intracellular adhesion molecule-1 and platelet-derived growth factor receptor beta and smooth muscle cell migration into the neointima. CONCLUSIONS These data demonstrate that an isolated daily application of both in vivo- and in vitro-activated human platelets results in the development of transplant arteriosclerosis in a humanized mouse transplantation model.

Abstract
Lower-extremity arterial disease is a major health problem with increasing prevalence, often leading to non-traumatic amputation, disability and mortality. The molecular mechanisms underpinning abnormal vascular wall remodeling are not fully understood. We hypothesized on the existence of a vascular tissue memory that may be transmitted through soluble signaling messengers, transferred from humans to healthy recipient animals, and consequently drive the recapitulation of arterial wall thickening and other vascular pathologies. We examined the effects of the intralesional infiltration for 6 days of arteriosclerotic popliteal artery-derived homogenates (100 µg of protein) into rats’ full-thickness wounds granulation tissue. Animals infiltrated with normal saline solution or healthy brachial arterial tissue homogenate obtained from traumatic amputation served as controls. The significant thickening of arteriolar walls was the constant outcome in two independent experiments for animals receiving arteriosclerotic tissue homogenates. This material induced other vascular morphological changes including an endothelial cell phenotypic reprogramming that mirrored the donor’s vascular histopathology. The immunohistochemical expression pattern of relevant vascular markers appeared to match between the human tissue and the corresponding recipient rats. These changes occurred within days of administration, and with no cross-species limitation. The identification of these “vascular disease drivers” may pave novel research avenues for atherosclerosis pathobiology.

Abstract
Background and aim: Since the relation between Helicobacter pylori (H. pylori) and atherosclerosis has been evidenced, we aimed to analyze whether there is a relationship between the patient's H. pylori infection and age, gender, BMI, blood lipids, and carotid plaque formation.Methods: 810 patients from January 2016 to December 2019 were enrolled in this study, and divided the subjects into H. pylori (+) group and H. pylori (-) group based on the results of UBT. To analyze whether H. pylori infection is related to gender, age, BMI, blood lipids, and neck vascular plaque formation.Results: The single-factor analysis showed that the BMI ≥ 25kg/m2, triglycerides >1.7 mmol/l, the formation of cervical plaques were significantly higher in patients infected with H. pylori in compared to normal cases. Also, multi-variant logistic regression analysis showed that H. pylori infection affects the BMI ≥ 25kg/m2 and triglycerides >1.7 mmol/l to induce vascular plaque. Also, we showed that patients with H. pylori infection are 1.424 times higher than the non-infected group to have triglycerides more elevated than 1.7mmol/l.Conclusion: In this study, we conclude that H. pylori infection is an independent risk factor for higher BMI (>25), triglyceride (>1.7 mmol/l), and neck vascular plaque formation. The multi-variant analysis showed that patients with H. pylori infection are prone to have higher BMI, triglycerides, and neck vascular plaque formation over 1.4-times higher in non-infected individuals.KEY MESSAGESH. pylori infection is an independent risk factor for higher BMI, triglyceride, and neck vascular plaque formation.H. pylori can accelerate vascular plaque formation through increasing BMI and triglyceride.

Abstract
BACKGROUND Graft vascular disease (GVD) is the main reason of late transplanted organ failure, which limits the long-term survival of patients. Murine aortic transplant is widely used in the field to understand the mechanisms leading to GVD. Currently, 3 major techniques, end-to-end anastomosis, sleeve suture and cuff technology, have been used to study the mechanism of GVD. However, which method is more suitable in mouse model of GVD? Herein, we compared these 3 surgical techniques in a mouse allograft arteriosclerosis model to determine the technique with the most appreciable outcomes. METHODS Male C57Bl/6 (H-2b) and BALB/c (H-2d) mice were used for aorta transplantation with these 3 techniques. These 3 techniques were compared with regard to donor artery acquisition time, artery anastomosis time, overall surgical time, the amount of bleeding of each technique and the success rate of surgery. Hematoxylin and eosin (H&E) and Masson staining were used to examine the pathological changes of grafted vessels. The protein expression of phospho-NF-κb P65 and PCNA were determined to validate laminar flow and proliferative capacity of neointima obtained from different surgical and control groups. RESULTS Sleeve suture had a shorter vascular anastomosis time and total operation time than end-to-end anastomosis and cuff technique. Sleeve suture and cuff technique had significantly fewer amount of bleeding from the site of vascular anastomosis than end-to-end anastomosis. Moreover, sleeve suture had the highest success rate among these 3 techniques. There was no difference in the degree of graft stenosis and collagen deposition between these 3 techniques. In addition, there was no significant difference in the expression of phospho-NF-κb P65and PCNA between the experimental group. CONCLUSIONS Sleeve suture is superior to end-to-end anastomosis and cuff technique with regard to vascular grafting in the murine model.

Abstract
Renal biopsy is useful to better understand the histological pattern of a lesion (glomerular, tubulointerstitial, and vascular) and the pathogenesis that leads to kidney failure. The potential impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the kidneys is still undetermined, and a variety of lesions are seen in the kidney tissue of coronavirus disease patients. This review is based on the morphological findings of patients described in case reports and a series of published cases. A search was conducted on MEDLINE and PubMed of case reports and case series of lesions in the presence of non-critical infection by SARS-CoV-2 published until 15/09/2020. We highlight the potential of the virus directly influencing the damage or the innate and adaptive immune response activating cytokine and procoagulant cascades, in addition to the genetic component triggering glomerular diseases, mainly collapsing focal segmental glomerulosclerosis, tubulointerstitial, and even vascular diseases. Kidney lesions caused by SARS-CoV-2 are frequent and have an impact on morbidity and mortality; thus, studies are needed to assess the morphological kidney changes and their mechanisms and may help define their spectrum and immediate or long-term impact.

Abstract
During the evolution of skeletons, terrestrial vertebrates acquired strong bones made of calcium-phosphate. By keeping the extracellular fluid in a supersaturated condition regarding calcium and phosphate ions, they created the bone when and where they wanted simply by providing a cue for precipitation. To secure this strategy, they acquired a novel endocrine system to strictly control the extracellular phosphate concentration. In response to phosphate intake, fibroblast growth factor-23 (FGF23) is secreted from the bone and acts on the kidney through binding to its receptor Klotho to increase urinary phosphate excretion, thereby maintaining phosphate homeostasis. The FGF23-Klotho endocrine system, when disrupted in mice, results in hyperphosphatemia and vascular calcification. Besides, mice lacking Klotho or FGF23 suffer from complex aging-like phenotypes, which are alleviated by placing them on a low- phosphate diet, indicating that phosphate is primarily responsible for the accelerated aging. Phosphate acquires the ability to induce cell damage and inflammation when precipitated with calcium. In the blood, calcium-phosphate crystals are adsorbed by serum protein fetuin-A and prevented from growing into large precipitates. Consequently, nanoparticles that comprised calcium-phosphate crystals and fetuin-A, termed calciprotein particles (CPPs), are generated and dispersed as colloids. CPPs increase in the blood with an increase in serum phosphate and age. Circulating CPP levels correlate positively with vascular stiffness and chronic non-infectious inflammation, raising the possibility that CPPs may be an endogenous pro-aging factor. Terrestrial vertebrates with the bone made of calcium- phosphate may be destined to age due to calcium-phosphate in the blood.

Abstract
Despite successful therapeutic strategies in the prevention and treatment of arteriosclerosis, the cardiovascular complications remain a major clinical and societal issue worldwide. Increased vascular calcification promotes arterial stiffness and accelerates cardiovascular morbidity and mortality. Upregulation of the Runx2 (Runt-related transcription factor 2), an essential osteogenic transcription factor for bone formation, in the cardiovascular system has emerged as an important regulator for adverse cellular events that drive cardiovascular pathology. This review discusses the regulatory mechanisms that are critical for Runx2 expression and function and highlights the dynamic and complex cross talks of a wide variety of posttranslational modifications, including phosphorylation, acetylation, ubiquitination, and O-linked β-N-acetylglucosamine modification, in regulating Runx2 stability, cellular localization, and osteogenic transcriptional activity. How the activation of an array of signaling cascades by circulating and local microenvironmental factors upregulates Runx2 in vascular cells and promotes Runx2-mediated osteogenic transdifferentiation of vascular smooth muscle cells and expression of inflammatory cytokines that accelerate macrophage infiltration and vascular osteoclast formation is summarized. Furthermore, the increasing appreciation of a new role of Runx2 upregulation in promoting vascular smooth muscle cell phenotypic switch, and Runx2 modulated by O-linked β-N-acetylglucosamine modification and Runx2-dependent repression of smooth muscle cell-specific gene expression are discussed. Further exploring the regulation of this key osteogenic transcription factor and its new perspectives in the vasculature will provide novel insights into the transcriptional regulation of vascular smooth muscle cell phenotype switch, reprograming, and vascular inflammation that promote the pathogenesis of arteriosclerosis.

Abstract
A 26-year-old man with a history of bronchial asthma was found to have high-density shadows along the bronchovascular bundle and in the subpleural area on computed tomography of the chest. Surgical lung biopsy specimens from the right S5 showed fibroelastosis in the subpleural and central airway area with alveolar destruction. He was diagnosed with airway-centered fibroelastosis of unknown cause after multidisciplinary discussions. The patient developed pulmonary hypertension and died 6 years later. The patient was younger in comparison to patients in earlier reports and had more obvious subpleural fibroelastic lesions in the upper lobes than in previously described cases.

Abstract
OBJECTIVE Vascular endothelial cells (ECs) normally maintain vascular homeostasis and are regulated by proinflammatory cytokines and reactive oxygen species. A human genome-wide association study identified that AIP1 (ASK1 [apoptosis signal-regulating kinase 1]-interacting protein-1; also identified as DAB2IP) gene variants confer susceptibility to cardiovascular disease, but the underlying mechanism is unknown. Approach and Results: We detected a normal AIP1 form (named AIP1A) in the healthy aorta, but a shorter form of AIP1 (named AIP1B) was found in diseased aortae that contained atherosclerotic plaques and graft arteriosclerosis. AIP1B transcription in resting ECs was suppressed through epigenetic inhibition by RIF1 (Rap1 [ras-related protein 1]-interacting factor 1)/H3K9 (histone H3 lysine 9) methyltransferase-mediated H3K9 trimethylation, and this inhibition was released by proinflammatory cytokines. AIP1A, but not AIP1B, was downregulated by proteolytic degradation through a Smurf1 (SMAD [suppressor of mothers against decapentaplegic miscellaneous] ubiquitylation regulatory factor 1)-dependent pathway in ECs under inflammation. Therefore, AIP1B was the major form present during inflammatory conditions. AIP1B, which lacks the N-terminal pleckstrin homology domain of AIP1A, localized to the mitochondria and augmented TNFα (tumor necrosis factor alpha)-induced mitochondrial reactive oxygen species generation and EC activation. AIP1B-ECTG (EC-specific AIP1B transgenic) mice exhibited augmented reactive oxygen species production, EC activation, and neointima formation in vascular remodeling models. CONCLUSIONS Our current study suggests that a shift from anti-inflammatory AIP1A to proinflammatory AIP1B during chronic inflammation plays a key role in inflammatory vascular diseases.

Abstract
BACKGROUND To elucidate the pathogenesis of benign prostatic enlargement (BPE) in humans due to chronic inflammation caused by arteriosclerosis, the relationships between prostate size and the degree of chronic inflammation induced by local arteriosclerosis were investigated. METHODS The present cohort included 50 subjects who underwent robot-assisted radical prostatectomy (RARP) in a prospective study. The presence or absence of local arteriosclerosis in the prostatic arteries removed during RARP was evaluated by microscopic assessment. Chronic inflammation in the prostate was judged according to both the density and the extent of inflammatory cells. The expression of lectin-like oxidized-low density lipoprotein receptor-1 (LOX-1) and the infiltration of macrophages in the prostate, which are high in arteriosclerosis, were investigated by immunohistochemistry. RESULTS Local arteriosclerosis was observed in 28% (14/50). Prostate size and the inflammation score were significantly increased in the presence of arteriosclerosis (P = 0.006, P < 0.001, respectively). There was also a significant increase of LOX-1 in the epithelial and stromal cells of the prostate in the presence of arteriosclerosis (all, P < 0.001). Concerning the presence of macrophages, subjects with arteriosclerosis had significantly more positive expression of ionized calcium-binding adapter molecule-1 (IBA-1), a marker of macrophages, than subjects without arteriosclerosis (P < 0.001). CONCLUSIONS In human surgical specimens, chronic inflammation owing to local arteriosclerosis of the prostatic arteries was significantly related to prostatic enlargement. Given the immunohistochemical analyses, the putative pathogenesis for this relationship is that LOX-1 induces macrophage infiltration, leading to BPE.

Abstract
BACKGROUND AND OBJECTIVE In this study, the interaction of pulsatile blood flow with the viscoelastic walls of the axisymmetric artery is numerically investigated for different severities of stenosis. The geometry of artery is modeled by an axisymmetric cylindrical tube with a symmetric stenosis in a two-dimensional case. The effects of stenosis severity on the axial velocity profile, pressure distribution, streamlines, wall shear stress, and wall radial displacement for the viscoelastic artery are also compared to the elastics artery. Furthermore, the effects of atherosclerosis and polycythemia diseases on the hemodynamics and the mechanical behavior of arterial walls are investigated. METHODS The pulsatile flow of non-Newtonian blood is simulated inside the viscoelastic artery using the COMSOL Multiphysics software (version 5) and by employing the fluid-structure interaction (FSI) method and the arbitrary Lagrangian-Eulerian (ALE) method. Moreover, finite element method (FEM) is used to solve the governing equations on the unstructured grids. For modeling the non-Newtonian blood fluid and the viscoelastic arterial wall, the modified Casson model, and generalized Maxwell model are used, respectively. RESULTS According to the results, with stenosis severity increasing from 25% to 75% at the time of maximum volumetric flow rate, the maximum value of axial velocity and its gradient increase 7.9 and 19.6 times, and the maximum wall shear stress of viscoelastic wall increases 24.2 times in the constriction zone. With the progression of the atherosclerosis disease (fivefold growth of arterial elastic modulus), the wall radial displacement of viscoelastic arterial walls decreases nearly 40%. CONCLUSIONS In this study, axial velocity profile, pressure distribution, streamlines, wall radial displacement, and wall shear stress were examined for different percentages of stenosis (25%, 50%, and 75%). The atherosclerosis disease was investigated by the fivefold growth of viscoelastic arterial elastic modulus and polycythemia disease was examined by the 21-fold increase in the yield stress of the blood fluid. Furthermore, the comparison of results between the elastic and viscoelastic arterial walls shows that the wall radial displacement for viscoelastic artery is lower than that for the elastic artery as much as 21.7% for the severe stenosis of 75%.

Abstract
SummaryGlycoprotein VI (GPVI) is the major platelet collagen receptor and plays a critical role in the process of thrombosis at sites of atherosclerotic lesions. This study evaluates the feasibility of radiolabeled soluble GPVI to identify injured arterial lesions. Radiolabeling was carried out using the iodogen method and resulted in the radioiodinated GPVI in radiochemical yields between 97–100%. The biodistribution of [125I]GPVI was determined in normal mice and demonstrated a blood clearance halftime of approximately 5.5 hours. Vascular lesions were induced in the carotid artery in wild type and ApoE -/- mice. Immediately after injury radioiodinated GPVI was injected intravenously. Binding of [123I]GPVI to carotid lesions was assessed by szinti-graphic in vivo imaging. Carotid arteries were explanted for ex vivo autoradiography and histological characterization of the lesion. In vivo and ex vivo imaging revealed substantial accumulation of radioiodinated GPVI in the injured artery wall, with a ratio of lesion to control vessel of 3:1 and 7:1, respectively. Because GPVI is the critical collagen receptor that mediates platelet adhesion to vascular lesions, soluble radiolabeled GPVI may be an agent for non-invasive imaging of thrombogenic thus, vulnerable atherosclerotic plaques.

Abstract
SummaryDuring recent years it has become increasingly recognized that the plasmin activation system is involved in the development of atherosclerosis.In this paper, we have studied the contribution of the plasmino-gen activation system in the development of atherosclerosis by cross-breeding apoE3-Leiden mice, which have a human-like lipid profile, with mice deficient in PAI-1 (plasminogen-activator inhibitor-1), u-PA (urokinase plasminogen activator), and t-PA (tissue plasminogen activator). Genetic compound offspring was used to evaluate the progression of atherosclerotic lesions after they were fed a variant atherogenic diet for 12 weeks. Lesion area of plaques in the aortic valve was not significantly different in apoE3-Leiden:PAI -/- and apoE3-Leiden:u-PA -/-mice as compared to apoE3-Leiden mice. In contrast, a significant 70 % reduction of the lesion area was observed in apoE3-Leiden:t-PA -/- mice as compared to control group apoE3-Leiden mice. In addition the early, regular fatty streaks and mild plaques increased in apoE3-Leiden:t-PA -/- mice, whereas the severe plaques (type IV and V) decreased in these animals.A lower deposition of collagen was observed in the atherosclerotic lesions of apoE3-Leiden:t-PA -/- mice as compared with apoE3-Leiden mice. Our results indicate for the first time that t-PA deficiency delayed the atherosclerotic process in this mouse model.

Abstract
SummaryThere is increasing recognition of the importance of vulnerable plaque and acute plaque rupture leading to thrombosis, in the pathogenesis of acute coronary syndromes. This is fueling a number of developments, including novel imaging modalities and potential plaque stabilization therapies. However, to date, no animal model of vulnerable plaque or plaque rupture has been established. Recent developments, particularly using Apo E knockout mice, appear set to provide key breakthroughs. The present status of our understanding of plaque vulnerability is therefore discussed, with a discussion of these current advances in animal models.

Abstract
SummaryLow serum albumin is a powerful predictor of cardiovascular adverse events in healthy subjects and patients with subclinical atherosclerosis. We investigated the association between serum albumin, traditional cardiovascular risk factors, markers of inflammation and cardiovascular outcome in 515 patients with advanced atherosclerosis and severe peripheral artery disease. Cardiovascular risk profile, serum albumin, serum amyloid A (SAA) and fibrinogen were obtained at baseline, and patients were followed for median 21 months (interquartile range 12 to 25) for the occurrence of major adverse cardiac events (MACE: myocardial infarction, percutaneous coronary interventions, coronary artery bypass graft, and death). We observed 135 MACE in 109 patients (21%). Cumulative event-free survival rates at 6, 12, and 24 months were 95%, 91%, and 80%, respectively. Low albumin predicted MACE independently of SAA and fibrinogen. Adjusted hazard ratios for the occurrence of MACE, any death, and the composite of death and MI according to increasing quartiles of albumin were 2.40, 1.14 and 1.09 (p<0.001), 2.94, 1.34 and 1.11 (p=0.003) and 3.63, 1.86 and 1.29 (p<0.001), respectively, as compared to the highest quartile. Considering albumin in conjunction with traditional cardiovascular risk factors (smoking, hyperlipidemia, hypertension and diabetes), we found that low albumin predicted MACE only in patients with a low risk profile (less than 3 risk factors) (p<0.001), whereas low albumin was not associated with MACE in patients with three or more risk factors (p=0.66). We conclude that low serum albumin is associated with cardiovascular outcome of patients with advanced atherosclerosis adding to the prognostic information of other inflammatory markers, and may be particularly useful for risk prediction in patients with few traditional risk factors.

Abstract
SummaryProliferation of vascular smooth muscle cells (VSMCs) is postulated to be one of the key events in the pathogenesis of atherosclerosis and restenosis. We investigated whether YD-3, a lowmolecular weight, non-peptide compound, could modulate proliferation of VSMCs in vitro and restenosis after balloon angioplasty in vivo. We examined the effect of YD-3 on thrombininduced VSMC proliferation by [3H]thymidine incorporation assay. The data demonstrated that YD-3 inhibited VSMC proliferation in a concentration-dependent manner. To define the mechanisms of YD-3 action, we found that YD-3 showed a profound inhibition on thrombin-induced Ras and ERK1/2 activities by using Western blotting analysis. Furthermore, oral administration of YD-3 exhibited a marked reduction in neointimal thickness using the carotid injury model in rats. Using immunochemical detection, our experiments also revealed that YD-3 significantly suppressed expression of the PAR-1 receptor, and markedly inhibited PAR-1-activating peptide (SFLLRN)-induced VSMC proliferation in a concentration-dependent manner. These results suggest that YD-3 inhibits thrombin-induced VSMC growth via the Rasand ERK1/2-mediated signaling pathway. Moreover, YD-3 also shows a developmental potential in the treatment of atherosclerosis and restenosis after vascular injury.

Abstract
SummaryMonocytes play a central role in the inflammatory disease atherosclerosis. CD14+CD16+ monocytes are considered proinflammatory monocytes, as they have an increased capacity to produce proinflammatory cytokines, such as TNF-α, and are elevated in various inflammatory diseases. We hypothesized that patients with coronary artery disease (CAD) have increased levels of CD14+CD16+ monocytes, and that CD14+CD16+ monocytes are associated with inflammation markers. We investigated CD14+CD16+ monocytes in 247 patients with CAD and 61 control subjects using flow cytometry. In addition serum concentrations of TNF-α, IL-6, and Hs-CRP were assessed. Patients with CAD had higher levels of CD14+CD16+ monocytes than controls (13.6% versus 11.4%; p<0.001). Logistic regression analysis including quartiles of CD14+CD16+ monocytes showed that CD14+CD16+ monocytes were associated with prevalence of CAD (OR 4.9, 95% CI 2.5–19.1, for subjects in the fourth quartile in comparison to subjects in the first quartile). The association between CD14+CD16+ monocytes and CAD remained independently significant after adjustment for most potential confounders (OR 5.0, 95% CI 1.2-20.0). Serum concentrations of TNF-α were elevated in subjects within the highest quartiles of CD14+CD16+ monocytes (p=0.018). Our study showed that increased numbers of CD14+CD16+ monocytes are associated with coronary atherosclerosis and TNF-α. In accordance, recent animal studies suggest a possibly important role of these monocytes in the development of atherosclerosis.

Abstract
SummaryPlatelets play a primary role in thrombus formation after plaque rupture. Platelets recognize the exposed collagen via Von Willebrand factor (VWF) and become activated. Saratin, an inhibitor of the VWF-dependent binding of platelets to collagen, may reduce the thrombotic risk associated to atherosclerosis. Our objective was to evaluate the antithrombotic effects of local treatment with saratin on human atherosclerotic lesions. Thrombus formation was assessed by the deposition of 111Inplatelets on different human atherosclerotic lesions under three local shear conditions (800,1700 and 3400/s) with blood derived from catheterized pigs. Human atherosclerotic lesions were locally treated with saratin (30 µg/ml) at 37ºC for 5 min and placed in the chamber. Under stenotic shear conditions of 800/s, saratin significantly (p<0.05) reduced platelet deposition triggered by human denuded vessel wall (44%), fatty streaks (47%), severely damaged vessel (50%) and atherosclerotic plaque (57%). Thrombus characterization by immunohistochemistry showed also a reduction in fibrin deposition in treated vessels. These results suggest that the local site-specific treatment with saratin inhibits atherosclerotic plaque thrombogenicity at haemodynamic conditions typical of moderately stenotic coronary arteries.

Abstract
The radiocephalic arteriovenous fistula (AVF) provides optimal vascular access for hemodialysis; it has a higher long-term patency rate and fewer complications than other vascular access methods. However, the AVF has a high primary failure rate. The presence of small-diameter vessels at anastomosis sites is an important risk factor for AVF failure. However, in a recent study, despite selecting an adequate artery and vein for creating an AVF by routine preoperative vascular mapping, AVF maturation and primary failure occurred. Thus, pre-existing arteriosclerosis at AVF anastomosis sites likely contributes to AVF failure. In this review, we discuss the relationship between pathologic changes and AVF patency in hemodialysis patients. Because arteriosclerosis of the major arteries such as the coronary and carotid arteries is associated with cardiovascular mortality, we also review the impact of arteriosclerosis of upper arm arteries at AVF anastomosis sites on cardiovascular mortality in hemodialysis patients.

Abstract
Schimke immuno-osseous dysplasia (SIOD) is a rare multisystem disorder with early mortality and steroid-resistant nephrotic syndrome (SRNS) progressing to end-stage kidney disease. We hypothesized that next-generation gene panel sequencing may unsurface oligosymptomatic cases of SIOD with potentially milder disease courses. We analyzed the renal and extrarenal phenotypic spectrum and genotype-phenotype associations in 34 patients from 28 families, the largest SMARCAL1-associated nephropathy cohort to date. In 11 patients the diagnosis was made unsuspectedly through SRNS gene panel testing. Renal disease first manifested at median age 4.5 yrs, with focal segmental glmerulosclerosis or minimal change nephropathy on biopsy and rapid progression to end-stage kidney disease (ESKD) at median age 8.7 yrs. Whereas patients diagnosed by phenotype more frequently developed severe extrarenal complications (cerebral ischemic events, septicemia) and were more likely to die before age 10 years than patients identified by SRNS-gene panel screening (88 vs. 40%), the subgroups did not differ with respect to age at proteinuria onset and progression to ESKD. Also, 10 of 11 children diagnosed unsuspectedly by Next Generation Sequencing were small at diagnosis and all showed progressive growth failure. Severe phenotypes were usually associated with biallelic truncating mutations and milder phenotypes with biallelic missense mutations. However, no genotype-phenotype correlation was observed for the renal disease course. In conclusion, while short stature is a reliable clue to SIOD in children with SRNS, other systemic features are highly variable. Our findings support routine SMARCAL1 testing also in non-syndromic SRNS.

Abstract
Spontaneous mortality of seemingly healthy, farmed Atlantic salmon (Salmo salar L) is an increasing problem in Norwegian aquaculture. In this study, we present a morphological study of the previously undescribed syndrome of arteriosclerosis of the ventral aorta and epicarditis of the adjacent bulbus arteriosus found in farmed Atlantic salmon, with wild-captured fish as a control group. Both the ventral aorta and epicardium are vital for correct arterial compliance and vascular resistance in the respiratory capillaries of the gills. We discuss the possible implications of ventral aorta arteriosclerosis and epicarditis for blood vascular health and in particular for the increasing frequency of spontaneous gill bleeding in farmed salmon. As both these conditions primarily occur in farmed salmon, we suggest that they should be considered pathological.

Abstract
Background In hemodialysis patients, fluid overload and malnutrition are accompanied by extracellular fluid (ECF) expansion and intracellular fluid (ICF) depletion, respectively. We investigated the relationship between ECF/ICF ratio (as an integrated marker reflecting both fluid overload and malnutrition) and survival and cardiovascular disease (CVD) in the context of malnutrition-inflammation-arteriosclerosis (MIA) complex. Methods Seventy-seven patients from a single hemodialysis unit were prospectively enrolled. The ECF/ICF volume was measured by segmental multi-frequency bioimpedance analysis. MIA and volume status were measured by serum albumin, C-reactive protein (CRP), pulse wave velocity (PWV) and plasma B-type natriuretic peptide (BNP), respectively. Results The mean ECF/ICF ratio was 0.56±0.06 and the cut-off value for maximum discrimination of survival was 0.57. Compared with the low ECF/ICF group, the high ECF/ICF group (ratio≥0.57, 42%) had higher all-cause mortality, CVD, CRP, PWV, and BNP, but lower serum albumin. During the 5-year follow-up, 24 all-cause mortality and 38 CVD occurred (18 and 24, respectively, in the high ECF/ICF group versus 6 and 14 respectively in the low ECF/ICF group, P<0.001). In the adjusted Cox analysis, the ECF/ICF ratio nullifies the effects of the MIA and volume status on survival and CVD and was an independent predictor of all-cause mortality and CVD: hazard ratio (95% confidence interval); 1.12 (1.01–1.25) and 1.09 (1.01–1.18) for a 0.01 increase in the ECF/ICF ratio. The degree of malnutrition (albumin), inflammation (CRP), arteriosclerosis (PWV), and fluid overload (BNP) were correlated well with the ECF/ICF ratio. Conclusions Hemodialysis patients with high ECF/ICF ratio are not only fluid overloaded, but malnourished and have stiff artery with more inflammation. The ECF/ICF ratio is highly related to the MIA complex, and is a major risk indicator for all-cause mortality and CVD.

Abstract
Anthocyanin-rich black soybeans have been used in traditional East Asian medicine to cure diseases related to oxidative stress and carcinogens, but not obesity. Our objective was to investigate the effects of anthocyanin-rich black soybean testa extracts (BBT), Glycine max (Chongja No. 3), on obesity. In total, 63 participants defined as overweight or obese by their body mass index (BMI >23) or waist circumference (WC >90 cm for males, >85 cm for females) were sorted into two groups: 32 receiving the trial medication (BBT, 2.5 g/d) and 31 receiving the placebo (starch, 2.5 g/d). Participants completed an 8-week, randomized, double-blinded, and placebo-controlled clinical trial. There were no significant differences between the two groups at the beginning of the trial, and both required the same safety assessments. Significant decreases in abdominal fat, described according to WC and hip circumference, and lipid profiles such as triacylglycerols (TG), low density lipoprotein cholesterol (LDLc), and non-high density lipoprotein cholesterol (non-HDLc) were observed in the BBT group at the conclusion of the clinical trial. The indicators for arteriosclerosis such as total cholesterol (TC)/HDLc and LDLc/HDLc were significantly decreased in the BBT group, but had not changed in the placebo group. With no difference between the two groups in energy-adjusted dietary intakes and physical activity, BBT was shown to strongly improve plasma lipid profiles, related to the reduction of WC (an indicator of abdominal fat) as long as high dietary fiber and low cholesterol diets were maintained. In conclusion, BBT can potentially be developed as a functional food for preventing abdominal obesity with high fiber and low cholesterol diets.

Abstract
The measurement of intima-media thickness (IMT) of large superficial arteries, especially the carotid, using high-resolution B-mode ultrasonography has emerged as one of the methods of choice for determining the anatomic extent of atherosclerosis and for assessing cardiovascular risk. IMT measurement obtained by ultrasonography correlates very well with pathohistologic measurements and the reproducibility of this technique is good. Population studies have shown a strong correlation between carotid IMT and several cardiovascular risk factors, and it has also been found to be associated with the extent of atherosclerosis and end-organ damage of high-risk patients. Therefore, increased carotid IMT is a measure of athero-sclerotic burden and a predictor of subsequent events. Because of its quantitative value, carotid IMT measurement is more and more frequently used in clinical trials to test the effects of different preventive measures, including drugs. More recently, there has been interest in the clinical use of this technique for detecting preclinical (asymptomatic) atherosclerosis and for identifying subjects at high risk. Measurement of carotid IMT could influence a clinician to intervene with medication and to use more aggressive treatment of risk factors in primary prevention, and in patients with atherosclerotic disease in whom there is evidence of progression and extension of atherosclerotic disease. For more extensive use of this method in clinical practice a consensus concerning the standardization of methods of measurement and precise definition of threshold between normal and pathologic IMT value is urgently needed.

Abstract
BACKGROUND Measurement of intima-media thickness (IMT) is a well established surrogate marker for cardiovascular endpoints. We studied the long-term effects of statins on femoral IMT and plaque scoring in the Atorvastatin versus Simvastatin on Atherosclerosis Progression (ASAP) study. METHODS AND RESULTS Three hundred and twenty-five patients with familial hypercholesterolaemia were randomized to either atorvastatin 80 mg/day or simvastatin 40 mg/day. IMT was measured at baseline and at 2 years. At baseline, femoral IMT was 1.69 mm in the atorvastatin group and 1.61 mm in the simvastatin group; at 2 years, IMT increased by 0.06 mm (P=0.24) and 0.15 mm (P=0.012), respectively. No significant differences were obvious between these two treatment arms (P=0.26). Femoral plaques were present in 64.7% in the atorvastatin group and 56.1% in the simvastatin group at baseline; after 2 years, these proportions rose to 66.0% (P=0.47) and 67.3% (P=0.02), respectively (P=0.87 between treatment arms). Carotid plaques were present in 6.3% versus 4.9%; after 2 years, these percentages were 5.0% (P=0.48) versus 5.5% (P=0.71), respectively (P=0.90 between treatment arms). CONCLUSION Our study indicates increased efficacy of atorvastatin 80 mg in retarding progression of atherosclerosis in the femoral artery compared with simvastatin 40 mg. Interestingly, in the carotid arteries these statins influenced IMT to a greater extent, whereas in the femoral artery the effects were more pronounced on plaque frequency. These findings underscore the generalized effects of lipid lowering on atherosclerosis.

Abstract
Stroke and neurologic dysfunction continue to complicate cardiac surgery despite improvements in cardiopulmonary bypass. Intra-aortic plaque disrupted during aortic manipulation is a known risk factor contributing to neurologic complications; therefore, avoidance of these plaques during aortic manipulation is important. Intraoperative epiaortic echocardiography, with its high sensitivity and specificity, has become the modality of choice for detecting plaque within the aorta during cardiac surgery and is superior to either transesophageal echocardiography or aortic palpation for this purpose. Recently the matrix x4 three-dimensional (3D) ultrasound probe (Philps Medical Systems) was introduced allowing both real time 3D imaging and electrocardiography-gated “full volume” imaging, which essentially acquires a larger image but requires 8 cardiac cycles. Modification of our routine scanning technique was required, employing a saline (about 30 mL) filled sterile sheath secured with a sterile elastic band (creating a saline pocket). There appears little difference in the sensitivity of either 2D or 3D imaging to detect plaque within the aorta. We found that live 3D was superior to 2D imaging in identifying, localizing, and defining the true extent of plaque in the aorta.

Abstract
Stiffness of the arterial wall and predicted vascular age as a predictor of cardiovascular disease when stress-induced hypertension in the military personnel. On the basis of the study of 156 men aged 30-55 years are considered diagnostic methods for stress-induced hypertension in the military personnel. Furthermore, using modern diagnostic methods determined stress effect on the development of stress-induced hypertension, and also the risk of cardiovascular diseases. In order to detect early signs of atherosclerosis used sphygmography, by means of which was determined by cardio ankle vascular index (CA VI), as well as the calculated vascular age. The study proposed a set of organizational, diagnostic and therapeutic measures to reduce the risk of cardiovascular diseases among military personnel exposed to occupational stressful load.

Abstract
The mortality rate is high in patients receiving hemodialysis (HD), atherosclerotic diseases being the major cause of death. As marker of clinical outcome, a prospective examination of atherosclerotic tests and atherosclerotic risk factors in patients receiving HD was performed. On April 2000, 84 patients receiving HD were followed up until April 2002. At entry to the study, several atherosclerotic tests, including ankle-arm blood pressure index (API), aortic calcification index (ACI), and atherosclerotic risk factors, were performed. In 36 patients with old thrombotic events, 26 had new thrombotic events. Of 48 patients without previous thrombotic events, 15 had new thrombotic events. During 2 years, 41 patients had new thrombotic events and 15 patients died due to thrombotic disorders. The HD durations were significantly longer in non-survivors than survivors and the body mass index was lower in non-survivors than survivors. There was a significant difference in the values of ACI and API between survivors and non-survivors, and between patients with and without thrombotic events. These findings suggest that the ACI and API have a prognostic value because they might predict the occurrence of thrombosis.

Abstract
Rupture of vulnerable atheroma often underlies acute coronary syndromes. Vulnerable plaques exhibit a paucity of vascular smooth muscle cells (VSMCs) in the cap. Therefore, decreased VSMC migration into the neointima may predispose to vulnerability. The balance between cell surface plasminogen activator activity and its inhibition [mediated primarily by plasminogen activator inhibitor type 1 (PAI-1)] modulates migration of diverse types of cells. We sought to determine whether increased expression of PAI-1 would decrease migration of VSMCs in vitro and neointimal cellularity in vivo in apolipo-protein E knockout (ApoE−-/–) mice fed a high-fat diet. Increased vessel wall expression of PAI-1 in transgenic mice was induced with the SM22α promoter. VSMC migration through Matrigel in vitro was quantified with laser scanning cytometry. Expression of PAI-1 was increased threefold in the aortic wall of SM22-PAI transgene-positive mice. Neointimal cellularity of vascular lesions was decreased by 26% ( p=0.01; n=5 each) in ApoE−-/– mice with the SM22-PAI transgene compared with ApoE−-/– mice. VSMCs explanted from transgene-positive mice exhibited twofold greater expression of PAI-1 and their migration was attenuated by 27% ( p=0.03). Accordingly, increased expression of PAI-1 protein by VSMCs reduces their migration in vitro and their contribution to neointimal cellularity in vivo.

Abstract
INTRODUCTION Thromboangiitis obliterans is an inflammatory occlusive vascular disease of young smokers that commonly involves the small and medium sized arteries and veins of the extremities. An important differential diagnosis of thromboangiitis obliterans is atherosclerotic arterial disease. An atypical presentation of thromboangiitis obliterans by involvement of mesenteric arteries has been described sporadically. CASE PRESENTATION We report the case of a patient presenting with Raynaud's phenomenon, ischemia of the upper and lower extremities, as well as mesenteric ischemia. The dramatic course of the disease advanced to gangrene of the calves and intestinal infarction. In this patient, angiographic and histologic features were consistent with thromboangiitis obliterans associated with atherosclerotic arteriopathy. DISCUSSION A review of the literature revealed 31 reported cases of mesenteric artery involvement by thromboangiitis obliterans. The overlap between thromboangiitis obliterans and atherosclerotic arteriopathy is rare but has recently focused attention in the literature. CONCLUSION In the differential diagnosis of mesenteric ischemia, thromboangiitis obliterans is a rare but important diagnosis that should be considered. In view of shared features of thromboangiitis obliterans and peripheral artery disease, awareness of their possible coexistence is needed in order to make the right diagnosis and offer proper treatment.

Abstract
OBJECTIVE Mesenteric phlebosclerosis (MP) is a disease characterized by calcification of the mesenteric vein, which causes chronic mesenteric ischemia. Recently, the long-term intake of gardenia fruit ('Sanshishi' in Japanese) has been attracting attention as a possible cause. Usually, only advanced, severe MP cases get reported. However, we suspected that some latent cases of this disease may exist. We performed this study in order to determine the prediagnostic cases at our outpatient departments of herbal (Kampo) medicine, with particular attention paid to the initial changes, such as any slight color change of the colon, as shown in colonoscopy. METHODS We recommend colonoscopy and computed tomography (CT) scans for patients with a long-term history of taking herbal medicines containing gardenia fruit. Clinical examinations were performed upon receiving patients' consent from December 2013 to November 2014. RESULTS Of the 103 patients who took gardenia fruit long-term, 29 agreed to be checked for MP. 14 patients underwent colonoscopy. Four patients were confirmed to have MP due to the presence of fibrotic deposition of the colonic membrane on histological inspection. Twenty-one patients underwent abdominal CT screening. Characteristic calcification of the mesenteric vein was observed on CT scans in 2 patients. All 4 MP patients took Kampo formulas containing gardenia fruit for more than 6.8 years. The other patients did not develop MP, despite long-term gardenia fruit intake. CONCLUSION We detected the latent and undiagnosed MP cases. All diagnoses were made while paying careful attention to any slight changes in colonoscopy and CT scans.

Abstract
We present the case of a 57-year-old hemodialysed male patient known with severe hypertension resistant to six classes of hypotensive medication, in maximal doses, correlated with increased ultrafiltration during the hemodialysis session. In this case, bilateral nephrectomy was performed as final treatment option for malignant hypertension, and histopathological examination of both kidneys emphasized arteriosclerosis lesions. The results consisted in better hypertension management, with a reduction in both the number and doses of antihypertensive drugs.

Abstract
Simvastatin (SIM) is anti-inflammatory. We used low density lipoprotein receptor knockout (LDLR-/-) mice and human aortic smooth muscle cells (HASMCs) as model systems to study the effect of SIM on arterial calcification and to explore the potential mechanisms contributing to this protective effect. High-fat diet (HFD) caused the LRLR -/- to develop dyslipidemia, diabetics, atherosclerosis and aortic smooth muscle calcification. SIM, N-acetyl cysteine (NAC, a ROS scavenger) and apocynin (APO, a NADPH oxidase inhibitor) did not significantly retard the development of dyslipidemia or diabetic. However, those treatments were still effective in attenuating the HFD-induced atherosclerosis and aortic smooth muscle calcification. These findings suggest that the protective effect of SIM against aortic calcification is not contributed by the cholesterol lowering effect. SIM, NAC and APO were found to attenuate the HFD induced elevation of serum TNF-α, soluble TNFR1 (sTNFR1), 3-nitro-tyrosine. We hypothesized that the pro-inflammatory cytokine, oxidative stress and TNFR1 played a role in inducing aortic calcification. We used HASMC to investigate the role of TNF-α, oxidative stress and TNFR1 in inducing aortic calcification and to elucidate the mechanism contributes the protective effect of SIM against aortic calcification. We demonstrated that treating HASMC with TNF-α induced cell Ca deposit and result in an increase in ALP, NADPH oxidase activity, NF-kB subunit p65, BMP2, MSX2, and RUNX2 expression. SIM suppressed the TNF-α induced activation of NADPH oxidase subunit p47, the above-mentioned bone markers and TNFR1 expression. Furthermore, p65, p47 and TNFR1 siRNAs inhibited the TNF-α-mediated stimulation of BMP-2, MSX2, RUNX2 expression. SIM, APO, and NAC either partially inhibit or completely block the TNF-α induced H2O2 or superoxide production. These results suggest that SIM may, independent of its cholesterol-lowering effect, suppresses the progression of vascular diseases through the inhibition of the inflammation mediators TNF-α and TNFR1.

Abstract
With an emphasis on evolving concepts in the field, we evaluated neuropathologic data from very old research volunteers whose brain autopsies were performed at the University of Kentucky Alzheimer's Disease Center, incorporating data from the Georgia Centenarian Study (n = 49 cases included), Nun Study (n = 17), and University of Kentucky Alzheimer's Disease Center (n = 11) cohorts. Average age of death was 102.0 (range: 98-107) years overall. Alzheimer's disease pathology was not universal (62% with "moderate" or "frequent" neuritic amyloid plaque densities), whereas frontotemporal lobar degeneration was absent. By contrast, some hippocampal neurofibrillary tangles (including primary age-related tauopathy) were observed in every case. Lewy body pathology was seen in 16.9% of subjects and hippocampal sclerosis of aging in 20.8%. We describe anatomic distributions of pigment-laden macrophages, expanded Virchow-Robin spaces, and arteriolosclerosis among Georgia Centenarians. Moderate or severe arteriolosclerosis pathology, throughout the brain, was associated with both hippocampal sclerosis of aging pathology and an ABCC9 gene variant. These results provide fresh insights into the complex cerebral multimorbidity, and a novel genetic risk factor, at the far end of the human aging spectrum.

Abstract
BACKGROUND With the association between diabetic nephropathy (DN) and renal outcome being increasingly clear, we aimed at creating a new DN pathological scoring system that could predict the renal outcome. METHODS We studied 205 patients with DN confirmed by renal biopsy, sometime between March 1985 and January 2010, who met the inclusion criteria. Renal biopsy included clinical parameters and Tervaert classifications. Hazard ratios (HRs) for death-censored end-stage renal disease (ESRD) were estimated by adjusted Cox proportional-hazards regression. The overall pathological risk score (D-score) was calculated by summing the products of beta coefficient and bootstrap-inclusion fractions, its predictive utility evaluated by Kaplan-Meier methods and c-statistics for a 10-year risk of ESRD. RESULTS The D-scores of glomerular classes 1, 2A, 2B, 3, and 4 were, respectively, 0, 3, 4, 6, and 6. Those of interstitial fibrosis and tubular atrophy classes 0, 1, 2, and 3 were 0, 7, 9, and 11, and those of interstitial inflammation classes 0, 1, and 2 were 0, 3, and 4, respectively. The D-score of hyalinosis class 2 was 3 and that of arteriosclerosis class 2 was 1. So, a patient's D-score could be 0-25. HRs for ESRD in patients with D-score ≤14, 15-18, 19-21, and 22-25 were, respectively, 1.00 (reference) 16.21 (95% confidence interval (CI), 1.86-140.90), 19.78 (95% CI, 2.15-182.40), and 45.46 (95% CI, 4.63-446.68) after adjusting for clinical factors. The c-statistics suggested a better predictive ability for a 10-year renal death with models that included the D-score. CONCLUSION Prediction of DN patients' renal outcome was better with the D-score than without it. Patients with a D-score ≤14 had excellent renal prognosis.
