Multilevel diabetic foot revascularization in COVID 19 patient: Case report
2021
Abstract Introduction Coronavirus 2019 (COVID-19) has been associated with endothelial dysfunction. This hypercoagulable state coming from the endothelial injury pones COVID-19 patients to a higher risk for thrombosis. COVID 19 diabetic patients are more exposed to peripheral vascular disease progression. Multilevel peripheral arterial disease is the main cause of critical limb ischemia. Vascular interventions are required to increase distal blood flow and reduce the risk of amputation. Presentation of case We report a case of complex revascularization in a diabetic patient with aggressive right foot lesions evolution after COVID-19 infection. The patient presenting a Peripheral arterial is…
Multivessel Intervention in Myocardial Infarction with Cardiogenic Shock: CULPRIT-SHOCK Trial Outcomes in the PL-ACS Registry
2021
Background: The aim of the study was a comparison of culprit-lesion-only (CL-PCI) with the multivessel percutaneous coronary intervention (MV-PCI) in terms of 30-day and 12-month mortality in a national registry. Methods: Patients from the PL-ACS registry with MI and CS were analyzed. Patients meeting the criteria of the CULPRIT-SHOCK trial were divided into two groups: CL-PCI and MV-PCI groups. Results: Of the 3265 patients in the PL-ACS registry with MI complicated by CS, the criteria of the CULPRIT-SHOCK trial were met by 2084 patients (63.8%). The CL-PCI was performed in 883 patients, and MV-PCI was performed in 1045 patients. After the propensity score matching analysis, 617 well-match…
Comparative study of post-natal retinal vascular development in mice models of iPLA2 inhibition and plasmalogen deficiency
2012
Purpose: Plasmalogens are particular phospholipids characterized by the presence of a vinyl-ether bond and of a polyunsaturated fatty acid (PUFA) at sn-1 and sn-2 positions of glycerol, respectively. Even if the plasmalogen content of organs and tissues is well documented, their biological functions are still enigmatic. Plasmalogen deficiency in DAPAT-/- mice leads to developmental abnormalities in retinal vasculature (Acar et al, ARVO 2007 E-Abstract 2978) and to persistent hyaloïd arteries. We hypothesize that plasmalogens regulate retinal vascular development through the liberation of PUFA by a plasmalogen-specific calcium-independent phospholipase A2 (iPLA2). We have performed a compara…
“Less invasive” surgery in the treatment of cutaneous chronic ulcers of the lower limb in elderly
2010
The role of treatment of vascular lesions of the legs is very important in the elderly. Pain, inability, bandages, periodicity of medications can seriously interfere with a good quality of life because of the lower compliance of geriatric patients to accept a surgical approach. To allow a new approach to vascular lesions the Authors propose a guideline in which the topic of “less invasive” surgery is underlined based on their pathophysiological causes. Patients affected with lesions of the legs are addressed to the Leg Ulcers Centre by general physicians and selected on the basis of age and comorbility to propose a therapeutical plan. General conditions, evaluation of lesions healing and of…
Zero-contrast percutaneous coronary interventions to preserve kidney function in patients with severe renal impairment and hemodialysis subjects
2019
Introduction Zero-contrast percutaneous coronary intervention (zero-PCI) is a new method for prevention of contrast-induced acute kidney injury (AKI) in patients with chronic kidney disease (CKD). However, evidence for its feasibility, safety and clinical utility is limited to reports of single cases or series of patients. Aim To present outcomes of zero-PCI in patients with severe CKD, including hemodialysis subjects, who were treated with this procedure in order to preserve their renal function. Material and methods Twenty-nine zero-PCIs were performed, mostly as a staged procedure, in 20 patients with advanced CKD. In this group, 4 patients were treated with hemodialysis but presented pr…
Cohort profile: Thrombolysis in Ischemic Stroke Patients (TRISP): a multicentre research collaboration
2018
PurposeThe ThRombolysis in Ischemic Stroke Patients (TRISP) collaboration aims to address clinically relevant questions about safety and outcomes of intravenous thrombolysis (IVT) and endovascular thrombectomy. The findings can provide observational information on treatment of patients derived from everyday clinical practice.ParticipantsTRISP is an open, investigator-driven collaborative research initiative of European stroke centres with expertise in treatment with revascularisation therapies and maintenance of hospital-based registries. All participating centres made a commitment to prospectively collect data on consecutive patients with stroke treated with IVT using standardised definiti…
Delivery of siHIF‐1α to Reconstruct Tumor Normoxic Microenvironment for Effective Chemotherapeutic and Photodynamic Anticancer Treatments
2021
The tumor hypoxic microenvironment not only induces genetic and epigenetic changes in tumor cells, immature vessels formation for oxygen demand, but also compromises the efficiency of therapeutic interventions. On the other hand, conventional therapeutic approaches which kill tumor cells or destroy tumor blood vessels to block nutrition and oxygen supply usually facilitate even harsher microenvironment. Thus, simultaneously relieving the strained response of tumor cells and blood vessels represents a promising strategy to reverse the adverse tumor hypoxic microenvironment. In the present study, an integrated amphiphilic system (RSCD) is designed based on Angiotensin II receptor blocker cand…
Managing Peripheral Artery Disease in Diabetic Patients: A Questionnaire Survey from Vascular Centers of the Mediterranean Federation for the Advanci…
2020
Background The Mediterranean Federation for the Advancing of Vascular Surgery (MeFAVS) was founded on October 1, 2018, to enhance cooperation among vascular professionals within Mediterranean countries. Due to its prominent social and economic impact on national health systems, diabetic arteriopathy has been selected as the very first topic to be investigated by the federation. Methods MeFAVS members were asked to reply to a questionnaire on the management of diabetic ischemic foot. Results were collected and analyzed statistically. The questionnaire consisted of 15 multiple choice answers regarding diabetic foot (DF) diagnosis and treatment. The questionnaire was submitted to 21 centers on…
