IgG4-related AAAs (IgG4-AAAs) exhibit vasculitis with elevated inflammatory marker levels. Matrix metalloproteinases (MMPs) degrade the extracellular matrix to destroy the aortic structures to progress aneurysm. This report examined pre- and postoperative serum MMPs and inflammatory marker levels to evaluate the prognosis of IgG4-AAAs after endovascular aortic repair (EVAR). Methods : Among 25 patient with inflammatory abdominal aortic aneurysms (>2-mm-thick periaortic fibrosis) treated with EVAR, IgG4-AAA was diagnosed in 14 patients, and the remaining 11 patients were classified as non-IgG4-AAA. IgG4-AAAs were categorized into cases with increased (IgG4-AAA-up; n = 6) or decreased (IgG4-AAA-down; n=8) postoperative serum IgG4 levels. Before EVAR and after 24 months, we compared the serum MMP, inflammatory marker levels, periaortic fibrosis, and aneurysm diameter. Results : IgG4-AAAs patients showed higher preoperative IL-6 levels, increased postoperative MMP-9 levels, and enlarged postoperative aneurysmal diameters compared with non-IgG4-AAA patients. Among IgG4-AAAs, IgG4-AAA-up exhibited higher preoperative MMP-9, higher preoperative monocytes and eosinophils, increased postoperative MMP-9 and IL-6, and larger aneurysm diameter than IgG4-AAA-down. All patients in IgG4-AAA-down showed shrunk preoperative aneurysm, although almost all patients in IgG4-AAA-up showed enlarged. In IgG4-AAA-up, IgG4/IgG ratio was significantly higher consistently before and after EVAR. MMP-9 was significantly correlated with IgG4 and IL-6. MMP-2 was not significantly different between patients with and without as well as between IgG4-AAA-up and IgG4-AAA-down. Conclusion: Increased postoperative MMP-9 and IL-6 in IgG4-AAA may accelerate aneurysmal progression after EVAR. IgG4-AAA-up exhibited increased IL-6 levels and larger aneurysm diameters following EVAR than IgG4-AAA-down and were considered as the high-risk group with a tendency toward progression. Before surgery, a high IgG4/IgG ratio, high MMP-9 concentrations, a high ratio of monocytes and eosinophils might predict IgG4-AAA-up.","PeriodicalId":206117,"journal":{"name":"Vascular Diseases and Therapeutics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126837828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was aimed to investigate the acute effects of myricetin on the pial microvascular alterations and oxygen-derived free radical formation, due to 30 min cerebral blood flow lowering (CBFL) and subsequent cerebral blood flow resumption (CBFR). Methods: Rat pial microvasculature was investigated using fluorescence microscopy through a closed cranial window. At first, arterioles were classified according to the Strahler’s ordering scheme. Then, arteriolar diameter, permeability increase, leukocyte adhesion to venular walls, perfused capillary length (CPL) and red blood cell velocity (VRBC) were quantified by computerized methods. Finally, reactive oxygen species (ROS) production was investigated in vivo by 2 ′ -7 ′ -dichlorofluorescein- diacetate assay and infarct size by 2,3,5-triphenyltetrazolium chloride staining. Results: After 30 min CBFL and 60 min CBFR, a decrease of arteriolar diameter, CPL and VRBC was detected; furthermore, increases in microvascular leakage and leukocyte adhesion were observed in hypoperfused animals. Conversely, myricetin administration induced dose-related arteriolar dilation, reduction in microvascular permeability as well as leukocyte adhesion when compared to those detected in bilateral common carotid artery occlusion-submitted animals; moreover, CPL and VRBC were preserved. In animals treated with myricetin the ROS production was blunted and infarct size significantly reduced. Conclusion: In conclusion, myricetin acute administration showed dose-related protective effects on rat pial microcirculation during CBFL and subsequent CBFR, inducing arteriolar dilation and inhibiting ROS formation, consequently preserving the blood brain barrier integrity.","PeriodicalId":206117,"journal":{"name":"Vascular Diseases and Therapeutics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130702998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Institutional review board approval was granted for this study, IRB #18-003517. Informed consent was waived by the institutional review board. This retrospective study reviewed Greenfield filter placement (n=26) and Tulip filter (n=203) removal. The electronic medical record was reviewed and a single author determined filter angle and caval penetration on the most recent available CT or catheter venogram. Filters removed with a snare were analyzed as routine removal and filters requiring additional devices or procedures were placed in a difficult removal group. Results: Greenfield filters had longer dwell time with a mean ± standard deviation of 811.3 ± 1398.1 days compared to 183.8 ± 262.1 days for Tulip filters (p=0.845). Filter tilt angle was not significantly different between the filter types 7.2 ± 4.7 for Greenfield filters and 5.5 ± 4.8 degrees for Tulip filters (p=0.09). Four (15.4%) Greenfield filters and 47 (23.2%) Tulip filters penetrated the caval wall >3 mm (P=0.37). Of the Tulip filters, those in the difficult removal group had a mean tilt of 7.6 ± 6.5 degrees compared to 4.6 ± 3.6 degrees in the routine removal group (p=0.0057). Conclusion: Greenfield IVC filters with longer dwell times demonstrate similar degrees of filter tilt and caval penetration as Tulip filters. A mean tilt of 7.6 ± 6.5 degrees indicates a filter which may require additional or alternative techniques for removal. *Correspondence to: Misra S, MD, FSIR FAHA, Professor of Radiology, Mayo Clinic, Department of Radiology, 200 First Street SW, Rochester, MN 55905, USA, Tel: 507-255-7208; Fax: 507-255-7872; E-mail: misra.sanjay@mayo.edu Received: November 04, 2019; Accepted: November 15, 2019; Published: November 18, 2019 Introduction Inferior vena cava (IVC) filters are commonly placed in patients at risk for pulmonary embolism (PE) or who have PE and a contraindication to anticoagulation, have failed anticoagulation, or have had a complication related to anticoagulation [1]. Over the past several decades, there have been numerous iterations to the IVC filter design and conically-shaped IVC filters are currently the most commonly used type of filter [2]. Permanent filters have largely been replaced by retrievable filters due to increased risk of lower extremity thrombosis associated with prolonged permanent filter dwell time [1,3,4]. Filter-related complications include caval wall penetration, IVC thrombosis, and in some cases, retrievable filters cannot be safely removed due to hook contact with the caval wall or strut penetration through the cava [1,5-7]. These issues tend to be magnified by the degree of filter tilt and duration ","PeriodicalId":206117,"journal":{"name":"Vascular Diseases and Therapeutics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125841138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for those with severe depression after chronic stroke, there is little to no information regarding response of depression to exercise addressing persistent physical impairments and dysfunction or response to exercise therapy for those who are severely depressed. Methods: We enrolled a male stroke survivor at 1.75 years post stroke, with severe depression. Measures collected at preand post-treatment were as follows: Beck Depression (mood); Fugl-Meyer (FM joint movement coordination); Berg Balance Scale (BBS); Timed Up and Go (TUG; mobility); Functional Independence Measure (FIM; subscales of Self-Care, Transfer, Locomotion); Craig Handicap Assessment and Reporting Technique (CHART; quality of life assessment of how patients with disabilities function in the community and at home); 36-Item Short Form Survey (SF36; quality of life measure); and the Stroke Impact Scale (SIS; stroke-specific quality of life measure). Exercise was scheduled as follows: 6mo therapy, five times/wk (1–2.5hrs/session); and additional 6mo, 2-3timeswk, and included aerobic exercise and coordination/strength training for balance and gait. The treatment protocol included exercises for balance and coordination of the lower limb, strengthening, gait coordination, and aerobics exercise on a stationary cycle. Results: Depression improved from severe to mild. The initial presence of severe depression did not preclude significant improvement in mobility and life role participation. Clinically significant gains were exhibited, not only in depression, but also in balance, mobility, and activities of daily living. Moreover, his quantified changes included clinically significant progression to categories of ‘low fall risk’ and ‘functionally independent’. He achieved important clinical and functional goals, as reflected by improved scores in measures of life role participation and personal milestones. Conclusion: Though this is a case study, it is reasonable to consider that a long-duration exercise program can be of great benefit in terms of functional and quality of life gains, regardless of the initial presence of severe depression. *Correspondence to: Daly JJ, Ph.D., Professor, Department of Neurology, College of Medicine, University of Florida, Director, Brain Rehabilitation Research Center, North Florida/South Georgia VA Medical Center, Florida, Tel: 1-216-402-8940; E-mail: janis.daly@neurology.ufl.edu","PeriodicalId":206117,"journal":{"name":"Vascular Diseases and Therapeutics","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123310472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
