The negative effects of reduced attention to standard guidelines for screening and surgery of abdominal aortic aneurysms during the coronavirus disease 2019 pandemic

Si pone in evidenza l'importanza dello screening nella popolazione per aneurismi dell'aorta addominale

Abdominal aorta angiosarcoma after endovascular aneurysm repair

Primary tumors originating within the wall of the arteries are rare and they frequently manifest late, making effective treatment a challenge. We describe here a case of Abdominal Aorta AngioSarcoma masqueraded as an infected EndoVascular Aortic Repair. The knowledge of this pathology from vascular surgeons and radiologist is crucial, because a prompt diagnosis and treatment can improve the prognosis

Re: "Endothelitis in COVID-19-positive patients after extremity amputation for acute thrombotic events"

Ilonzo et al reported, in their recent and interesting article, their clinical experience in 4 patients affected by COVID-19 and undergoing major limb amputation secondary to acute irreversible ischemia. On histological examination with hematoxylin/eosin they found inflammatory cells associated with endothelium/apoptotic bodies, mononuclear cells, small vessel congestion, and lymphocytic endotheliitis and concluded that the findings in these patients is more likely an infectious angiitis due to COVID-19. In our experience we have observed numerous cases of venous and arterial thromboembolism not only in the acute phase of COVID-19, but (even more interestingly) even after recovery. Whether SARS-CoV-2 is able to directly attack vascular endothelial cells expressing high levels of ACE2, and then lead to abnormal coagulation and sepsis, still needs to be explored

Endovascular Surgery during COVID 19 virus pandemic as a valid alternative to open surgery

Lo studio sottolinea i vantaggi della chirurgia endovascolare durante la fase acuta della pandemia da COVID1

Acute arterial and deep venous thromboembolism in COVID-19 patients. Risk factors and personalized therapy

The Lombardy region suffered severely during the acute phase of the coronavirus diease 2019 outbreak in Italy (Mar-Apr 2020) with 16,000 diagnosed coronavirus disease 2019-related deaths (49% of the total coronavirus disease 2019-related deaths in Italy). In the area surrounding Pavia during the critical stage of the outbreak (Mar-Apr 2020), 1,225 of the documented 4,200 deaths were related to coronavirus disease 2019 infection, with a mortality rate of 181/100,000 inhabitants and an increase in deaths of 138% compared with the same period during previous years. Our aim was to report the experience of the Department of Vascular Surgery of Pavia (Lombardy, Italy), including the lessons learned and future perspectives regarding the management of coronavirus disease 2019 patients who developed severe acute ischemia with impending lower limb loss or deep vein thrombosis

Identification of a novel susceptibility locus at 13q34 and refinement of the 20p12.2 region as a multi-signal locus associated with bladder cancer risk in individuals of european ancestry

Candidate gene and genome-wide association studies (GWAS) have identified 15 independent genomic regions associated with bladder cancer risk. In search for additional susceptibility variants, we followed up on four promising single-nucleotide polymorphisms (SNPs) that had not achieved genome-wide significance in 6911 cases and 11 814 controls (rs6104690, rs4510656, rs5003154 and rs4907479, P < 1 7 10(-6)), using additional data from existing GWAS datasets and targeted genotyping for studies that did not have GWAS data. In a combined analysis, which included data on up to 15 058 cases and 286 270 controls, two SNPs achieved genome-wide statistical significance: rs6104690 in a gene desert at 20p12.2 (P = 2.19 7 10(-11)) and rs4907479 within the MCF2L gene at 13q34 (P = 3.3 7 10(-10)). Imputation and fine-mapping analyses were performed in these two regions for a subset of 5551 bladder cancer cases and 10 242 controls. Analyses at the 13q34 region suggest a single signal marked by rs4907479. In contrast, we detected two signals in the 20p12.2 region-the first signal is marked by rs6104690, and the second signal is marked by two moderately correlated SNPs (r(2) = 0.53), rs6108803 and the previously reported rs62185668. The second 20p12.2 signal is more strongly associated with the risk of muscle-invasive (T2-T4 stage) compared with non-muscle-invasive (Ta, T1 stage) bladder cancer (case-case P 64 0.02 for both rs62185668 and rs6108803). Functional analyses are needed to explore the biological mechanisms underlying these novel genetic associations with risk for bladder cancer
