We evaluated the safety and efficacy of multilayer flow modulator (MFM) stents (Cardiatis, Isnes, Belgium) for the treatment of complex aortic lesions.
A systematic electronic research was conducted for studies reported from December 2008 to May 2020. Data extracted from 15 eligible case series (CS) were appropriately pooled and analyzed in a meta-analysis. The patient baseline characteristics were recorded, and 16 outcomes of interest were studied. The primary end points included 30-day all-cause and aneurysm-related mortality, aneurysm-related mortality at 1year, vessel patency, and any endoleaks, ruptures, reinterventions, and aneurysm exclusion at the end of follow-up.
A total of 39 studies (15 CS and 24 case reports), involving 429 patients, met the inclusion criteria. Overall, 436 lesions were treated, and 1521 aortic branches were covered by the multilayer stent. The mean follow-up for the 15 CS with 404 patients was 14.6months. Compliance with the instructions for use was reported by eight CS, wcause and aneurysm-related mortality rates combined with the low crude spinal cord ischemia and renal failure rates indicate the use of MFM stents is a good treatment option for complex aortic lesions in the short- and mid-term periods. The lack of long-term follow-up warrants further research concerning the efficacy of the device in the long term.
The results from the present review and meta-analysis have indicated the safety and efficacy of MFM stents for treating challenging aortic pathologic lesions when used as first-line treatment and within the instructions for use. The almost zero pooled 30-day all-cause and aneurysm-related mortality rates combined with the low crude spinal cord ischemia and renal failure rates indicate the use of MFM stents is a good treatment option for complex aortic lesions in the short- and mid-term periods. The lack of long-term follow-up warrants further research concerning the efficacy of the device in the long term.
Statin therapy, associated with improved short-term survival after treatment of abdominal aortic aneurysms (AAAs), may also predispose to muscle side effects. Evidence on statin-related sarcopenia is limited mainly to muscle function and it is subject to several sources of bias. In the long-term, postoperative development of sarcopenia is linked to mortality after endovascular repair (EVAR). We investigated statin use and long-term postoperative mortality after EVAR in relation to objective measurable markers of sarcopenia (psoas muscle surface area and density).
Altogether 216 AAA patients treated with EVAR between 2006 and 2014 at Tampere University Hospital (Finland) were retrospectively studied. Psoas muscle parameters at the L3 level were evaluated from baseline and mainly one- to three-year follow-up computed tomography (CT) studies. Cox regression was used to study the association between statin medication, psoas muscle changes, and all-cause mortality.
The majority of patients were male (87%) and mean age was 77.7 years (SD 7.4). Median duration of follow-up was 6.3 years (IQR 3.5) with a total mortality of 54.2% (n=117). Regardless of a higher burden of comorbidities, statin users (n=119) had lower mortality when compared to non-users (multivariable HR 0.69, 95% CI 0.48-0.99, p = .048). Furthermore, statin use was not associated with inferior muscle parameter values and the relative change in psoas muscle area was actually lower in statin users compared to non-users (-15.7% and -21.1%, p<.046).
Statin use is associated with lower long-term mortality among patients undergoing EVAR without predisposing to increased sarcopenia.

Vascular graft infection (VGI) is a serious complication with a high mortality and morbidity rate. Several measures could be taken to reduce the risk. One of them are silver containing vascular grafts. However, to date, no clinical advantages have been reported. This study reviews the outcome of preclinical studies focusing on the role of commercially available silver coated grafts in the prevention of VGI.
A systematic review was performed with a focus on the preclinical role of commercially available silver coated vascular grafts in the prevention and treatment of VGI. A comprehensive search was conducted in Medline, Embase and Web of Science.
Nine in vitro and five in vivo studies were included. Two commercial grafts were used (INTERGARD SILVER™ and Silver Graft™). In vitro studies used both gram-positive and gram-negative strains. A positive antimicrobial effect was observed in seven out of nine studies (77.8%). A delayed antifungal effect against Candida species was observed in vitro but disappeareded at this time to guide the appropriate use of silver grafts in the future.
Endovascular aneurysm repair (EVAR) is associated with worse outcomes in patients whose anatomy does not meet the device instructions for use (IFU). However, whether open surgical repair (OSR) and commercially available fenestrated EVAR (Zenith Fenestrated [ZFEN]) represent better options for these patients is unknown.
We identified all patients without prior aortic surgery undergoing elective repair of abdominal aortic aneurysms with neck length ≥4mm at a single institution with EVAR, OSR, and ZFEN. We applied device-specific aneurysm neck-related IFU to EVAR patients, and a generic EVAR IFU to ZFEN and OSR patients. Long-term outcomes were studied using propensity scores with inverse probability weighting. gp91ds-tat cost We compared outcomes in patients undergoing EVAR by adherence to IFU and outcomes by repair types in the subset of patients not meeting IFU.
Of 652 patients (474 EVAR, 34 ZFEN, 143 OSR), 211 had measurements outside of standard EVAR IFU (109 EVAR [23%], 27 ZFEN [80%], and 74 OSR [52%]). Perioperativ the comparison to EVAR (HR 0.6 [0.3-1.1], P= .1).
Treatment outside device-specific IFU is associated with adverse long-term outcomes. Open surgical repair is associated with higher long-term survival in patients who fall outside of the EVAR IFU and should be favored over EVAR or ZFEN in suitable patients. A three-vessel-based fenestrated strategy may not be a durable solution for difficult aortic necks, but more data are needed to evaluate the performance of newer, four-vessel devices.

To evaluate the influence of baseline psychological distress on patient-reported outcomes (PROs) after arthroscopic hip surgery for femoroacetabular impingement at a minimum of 5 years.
Demographic and intraoperative data were prospectively collected from patients who underwent primary arthroscopic hip surgery for femoroacetabular impingement and labral tears after failure of conservative management between June 2012 and December 2014. Included patients had preoperative and minimum 5-year postoperative PROs and visual analog scale scores for pain and satisfaction. The 12-item Short Form Health Survey (SF-12) Mental Component Summary (MCS) score was used to stratify patients into 2 cohorts Patients with an average or above-average score (SF-12 MCS score ≥ 50) were considered psychologically non-distressed, whereas those who scored below average (SF-12 MCS score < 50) were considered to have psychological distress. Distressed patients were propensity matched by age, sex, and body mass index to an equal n obtained by patients without preoperative psychological distress.

Level III, retrospective comparative study.Pathological vascular remodeling contributes to the development of restenosis following intraluminal interventions, transplant vasculopathy, and pulmonary arterial hypertension. Activation of the tumor suppressor p53 may counteract vascular remodeling by inhibiting aberrant proliferation of vascular smooth muscle cells and repressing vascular inflammation. In particular, the development of different lines of small-molecule p53 activators ignites the hope of treating remodeling-associated vascular diseases by targeting p53 pharmacologically. In this review, we discuss the relationships between p53 and pathological vascular remodeling, and summarize current experimental data suggesting that drugging the p53 pathway may represent a novel strategy to prevent the development of vascular remodeling.The neuroactive steroid allopregnanolone (ALLO) is an endogenous positive allosteric modulator of GABA type A receptor (GABAAR), and the down-regulation of its biosynthesis have been attributed to the development of mood disorders, such as depression, anxiety and post-traumatic stress disorder (PTSD). ALLO mediated depression/anxiety involves GABAergic mechanisms and appears to be related to brain-derived neurotrophic factor (BDNF), dopamine receptor, glutamate neurotransmission, and Ca2+ channel. In the clinical, brexanolone, as a newly developed intravenous ALLO preparation, has been approved for the treatment of postpartum depression (PPD). In addition, traditional antidepressants such as selective serotonin reuptake inhibitor (SSRI) could reverse ALLO decline. Recently, the translocation protein (TSPO, 18 kDa), which involves in the speed-limiting step of ALLO synthesis, and ALLO derivatization have been identified as new directions for antidepressant therapy. This review provides an overview of ALLO researches in animal model and patients, discusses its role in the development and treatment of depression/anxiety, and directs its therapeutic potential in future.Reports of the beneficial roles of butyrate in cardiovascular diseases, such as atherosclerosis and ischemic stroke, are becoming increasingly abundant. However, the mechanisms of its bioactivities remain largely unknown. In this study, we explored the effects of butyrate on endothelial dysfunction and its potential underlying mechanism. In our study, ApoE-/- mice were fed with high-fat diet (HFD) for ten weeks to produce atherosclerosis models and concurrently treated with or without sodium butyrate daily. Thoracic aortas were subsequently isolated from C57BL/6 wild-type (WT), PPARδ-/-, endothelial-specific PPARδ wild-type (EC-specific PPARδ WT) and endothelial-specific PPARδ knockout (EC-specific PPARδ KO) mice were stimulated with interleukin (IL)-1β with or without butyrate ex vivo. Our results demonstrated that butyrate treatment rescued the impaired endothelium-dependent relaxations (EDRs) in thoracic aortas of HFD-fed ApoE-/- mice. Butyrate also rescued impaired EDRs in IL-1β-treated thoracic aorta rinthe PPARδ/miR-181b pathway.Natural cannabidiol ((-)-CBD) and its derivatives have increased interest for medicinal applications due to their broad biological activity spectrum, including targeting of the cannabinoid receptors type 1 (CB1R) and type 2 (CB2R). Herein, we synthesized the (+)-enantiomer of CBD and its derivative (+)-CBD hydroxypentylester ((+)-CBD-HPE) that showed enhanced CB1R and CB2R binding and functional activities compared to their respective (-) enantiomers. (+)-CBD-HPE Ki values for CB1R and CB2R were 3.1 ± 1.1 and 0.8 ± 0.1 nM respectively acting as CB1R antagonist and CB2R agonist. We further tested the capacity of (+)-CBD-HPE to prevent hyperglycemia and its complications in a mouse model. (+)-CBD-HPE significantly reduced streptozotocin (STZ)-induced hyperglycemia and glucose intolerance by preserving pancreatic beta cell mass. (+)-CBD-HPE significantly reduced activation of NF-κB by phosphorylation by 15% compared to STZ-vehicle mice, and CD3+ T cell infiltration into the islets was avoided. Consequently, (+)-CBD-HPE prevented STZ-induced apoptosis in islets.
