Abstract
Background: In the latest American Heart Association guidelines, influenza vaccination is recommended for patients with peripheral arterial disease (PAD). The vaccination coverage in this specific population is currently unknown. This study aims to determine the adherence to influenza vaccination in a PAD population and identify associated determinants. Patients and methods. Hospitalized patients and outpatients with PAD from two university departments of vascular medicine were prospectively included. A questionnaire was administered to collect sociodemographic data, cardiovascular risk factors, influenza vaccination status, history of cardiovascular disease, and perception and knowledge about vaccination. Logistic regression was conducted to assess vaccination determinants. Results: Over a six-month period, 494 patients were included (median age 69.5, IQR [63-77], 78% male). Overall, 60.1% were either vaccinated or intended to be (Group 1). Vaccination was associated with age (odds-ratio [OR]=1.055, 95% confidence intervals [95%CI]: 1.035-1.075, p<0.0001), abdominal aorta aneurysm (OR=0.390, 95%CI: 0.229-0.664, p=0.001), chronic obstructive pulmonary disease (OR=0.545, 95%CI: 0.367-0.810, p=0.003), chronic renal disease (OR=0.630, 95%CI: 0.400-0.993, p=0.046), and valvulopathy (OR=2.444, 95%CI: 1.122-5.326, p=0.025). Only 25.3% received vaccination information mainly from their general practitioners. Among patients against vaccination, 59.9% considered themselves not concerned about potential influenza consequences on their PAD, and 37.6% did not intend to change their decision. Conclusions: This study highlights the low adherence to influenza vaccination in the PAD population of 2 university hospital centers. Vaccination is often related to age, and there is a need for adapted information regarding influenza consequences on cardiovascular disease overall, particularly on PAD. Addressing common information and advice about vaccination will be a challenge.

Abstract
BACKGROUND Chronic limb-threatening ischemia (CLTI) is the end-stage of peripheral arterial disease (PAD) posing a high risk for limb loss and mortality. This study aims to evaluate and list possible predictors of major adverse limb events (MALEs) in CLTI patients with tissue loss. METHODS This retrospective study included all Rutherford-Becker stage 5 or 6 patients who required foot debridement and revascularization in our department from January 2016 to December 2018. The limbs were classified according to the TASC II, GLASS and WiFI grading systems. The primary composite outcome was MALEs at 2 years. The secondary outcomes included all-cause mortality, primary patency, freedom from reintervention, and major amputation. Kaplan-Meier estimates were used to determine the event rates, and Cox proportional hazards model with the index MALE as a time-dependent covariate was used to search for MALEs predictors. RESULTS Of 241 included patients, 19 underwent open surgeries (7.9 %) 207 had endovascular interventions (85.9 %) and 15 required a hybrid approach (6.2 %). On univariate analysis, patients who experienced MALEs (n = 111) more often required hemodialysis (25 vs 15; p = .02), presented with more complex lesions (TASC D on femoropopliteal (p = .05) or below the knee (BTK) arteries (p = .006) with increasing infra-inguinal GLASS Stage (p < .0001)), a history of index limb open (p = .009) or endovascular (p = .049) revascularization, an occluded tibial artery (p = .002 for the posterior tibial and p = .052 for the anterior tibial), or a "desert foot" (p = .02). The CRP level was also higher at admission (p = .001). Technical success of BTK revascularization significantly reduced MALEs (p < .0001) along with the number of patent BTK vessels (p = .0007). Independent predictors of MALEs included hemodialysis (HR = 2.00; 95%CI: 1.14 to 3.39), pulsatile arterial pressure (HR = 1.01; 95%CI: 1.00 to 1.03) and the infra-inguinal GLASS Stage (HR = 2.50; 95%CI: 1.17 to 5.82). We could not correlate our results with the WiFI scores for amputation risk and revascularization benefit. CONCLUSION For patients with CLTI at the stage of trophic disorders, with or without a history of index limb revascularization, the GLASS successfully predicted MALEs. Hemodialysis and high pulsatile arterial pressure increased the risk of MALEs. The WiFI score did not demonstrate its interest in this subgroup of patients.

Abstract
BACKGROUND Iloprost has been proposed as an alternative to amputation in Critical Limb Ischemia (CLI) patients when revascularization was unsuccessful or not possible. Nonetheless, there is limited evidence of its benefit. The main objective was to evaluate the effectiveness of iloprost and the secondary objective was to evaluate its safety. METHODS In this cohort study including CLI patients from the COPART registry from 2006/10 to 2021/01, patients exposed to iloprost were matched with up to three unexposed patients according to age, sex, and Propensity Score (PS) for exposure to iloprost. The main outcome combined the occurrence of all-cause death and major amputations; survival was assessed over one-year using Kaplan-Meier estimates and Cox model analyses. Major Adverse Cardiovascular Events (MACE) were chosen as the safety outcome; the association with iloprost was estimated using a logistic regression model. RESULTS Among 1850 CLI patients, 201 were exposed to iloprost (71.6% men; median age: 72 years vs. 72.1%; 75 years for unexposed). In 134 exposed patients matched to 375 unexposed patients, 14 major amputations and 24 deaths occurred in exposed patients (28.4%) vs. 33 and 46 respectively in the unexposed patients (20.9%). The hazard ratio (HR) was of 1.49 (95% Confidence Interval: 1.01-2.20). The association remained in the subgroup of "no option" patients (HR: 1.74; [1.01-2.20]). Regarding safety, 21/201 (10.7%) exposed patients experienced MACE vs. 146/1649 (9.41%) unexposed patients (unadjusted Odds Ratio [OR]: 1.17 [0.72-1.90]; adjusted OR: 1.23 [0.72-2.11]). CONCLUSION The study did not find any benefit of iloprost in CLI patients and even suggested a deleterious effect.

Abstract
Data regarding the safety of co-administration of ibrutinib with anticoagulants in real-life settings are scarce. Using a nationwide database, we conducted a nested case-control study in a cohort of new users of ibrutinib to assess the risk of clinically relevant bleeding (CRB) associated with anticoagulation. Cases were patients with a diagnosis of CRB, defined as hospitalization with a diagnosis of bleeding. The date of CRB constituted the index date. Up to four controls were matched on sex, age at index date and duration of follow-up. The risk of CRB associated with anticoagulation in patients receiving ibrutinib was estimated using conditional logistic regression models, providing odds ratios (OR) adjusted for risk factors of bleeding. Among 614 cases and 2407 matched controls, the risk of CRB was significantly higher in patients receiving both ibrutinib and anticoagulants (adjusted OR [aOR] 2.54, confidence interval [CI] 95% [1.94; 3.32]). When considering anticoagulant class, aOR was 1.99 (CI 95% [1.19; 3.33]) for VKA, 2.48 (CI 95% [1.76; 3.47]) for direct oral anticoagulants and 3.40 (CI 95% [2.01; 5.75]) for parenteral anticoagulants. In conclusion, this study found a 2.5-fold increased risk of CRB in patients receiving both ibrutinib and anticoagulants in real-life settings, and similar aOR among oral anticoagulants.

Abstract
OBJECTIVE Inflammatory abdominal aortic aneurysms (InflAAAs) account for 5 - 10% of aortic aneurysms and are characterised by retroperitoneal fibrosis. Diagnosis is often delayed, and doubts remain about the optimal management strategy. This scoping review describes the current state of knowledge on InflAAAs. METHODS Medline, PubMed, EMBASE, and Scopus were searched for relevant studies that evaluated the diagnosis and treatment of InflAAAs. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol was followed. RESULTS Fifty-seven papers were selected (low level of evidence), which included 1 554 patients, who were mostly male and heavy smokers. A triad of chronic abdominal or back pain, weight loss, and elevated inflammatory markers was highly suggestive of the diagnosis but rarely present, and fever was noted only randomly. A mantle sign was seen on computed tomography angiography (CTA) in 73 - 100% of patients. Open surgical repair (OSR) and endovascular aortic aneurysm repair (EVAR) was reported in 1 376 and 178 patients, respectively. OSR was associated with significant iatrogenic bowel (n = 22), urinary tract system (n = 7), venous (n = 30), pancreatic (n = 6), and splenic (n = 5) injuries, while EVAR was associated with lower 30 day mortality (0 - 5% vs. 0 - 32%). One and two year mortality rates were similar between the two treatment modalities (0 - 20% and 0 - 36%, respectively). EVAR was more often associated with post-operative progression of inflammation (17% vs. 0.4%), and a higher frequency of persistent hydronephrosis (> 50%) and limb occlusion (20%). Used in < 10% of patients, corticosteroids led to complete pain relief and a reduction in peri-aortic inflammation within 6 - 18 months. CONCLUSION InflAAAs are characterised by non-specific symptoms, with the mantle sign on CTA being pathognomonic. Corticosteroids may be considered a basic treatment that all patients should receive initially. Low quality data indicate that EVAR (vs. OSR) is associated with fewer intra-operative complications and lower peri-operative mortality but more late fibrosis related adverse events. International multicentre registries are required to gather more insights into this challenging pathology.

Abstract
Lower-limb peripheral arterial disease (PAD), is a common manifestation of systemic atherosclerosis, resulting from a partial or complete obstruction of at least one lower-limb arteries. PAD is a major endemic disease with an excess risk of major cardiovascular events and death. It also leads to disability, high rates of lower-limb adverse events and non-traumatic amputation. In patients with diabetes, PAD is particularly frequent and has a worse prognosis than in patients without diabetes. The risk factors of PAD are comparable to those for cardiovascular disease. The ankle-brachial index is usually recommended to screen PAD despite its limited performance in patients with diabetes, affected by the presence of peripheral neuropathy, medial arterial calcification, incompressible arteries and infection. Toe brachial index and toe pressure emerge as alternative screening tools. The management of PAD requires strict control of cardiovascular risk factors including diabetes, hypertension and dyslipidaemia, the use of antiplatelet agents and lifestyle management, to reduce cardiovascular adverse events, but few randomized controlled trials have evaluated the benefits of these treatments in PAD. Several advances have been achieved in endovascular and surgical revascularization procedures, with obvious improvement in PAD prognosis. Further studies are required to increase our understanding of the pathophysiology of PAD and to evaluate the interest of different therapeutic strategies in the occurrence and progression of PAD in patients with diabetes. Here, we present a narrative and contemporary review to synthesize the key epidemiology findings, screening and diagnosis methods, and major therapeutic advances regarding PAD in patients with diabetes.

Abstract
An objective hemodynamic assessment is mandatory to confirm Critical Limb Ischemia (CLI). Toe pressure measurement is recommended. We compared toe measurements obtained using the Laser Doppler method (LD) (PERIMED PeriFlux, Sweden) considered as the reference test, with those obtained with a portable device using photoplethysmography (PPG) (Sys Toe Atys Medical, France). A total of 93 (123 legs) patients from 3 French hospitals with a clinical suspicion of CLI were included and had measurements with each device carried out by skilled operators. PPG was unable to provide a measurement in 10 patients. Lin's Coefficient correlation concordance (CCC) and Bland and Altman's scatter plot were analyzed for the 83 remaining patients, CCC was .84 95%CI (.77-.89). For detection of CLI, Cohen's kappa was .67 95%CI (.53-.81). The PPG device is fairly reliable for toe pressure measurement in patients suspected of CLI and could be useful when LD is not available. However, it fails to deliver a measurement in approximately 10% of cases. No conclusion should be made about CLI for these patients when no measurement is obtainable and other methods should be used (LD, transcutaneous oxygen pressure) to assess perfusion of the limbs.

Abstract
Subinhibitory doses of nystatin in the culture medium of Candida albicans gave yeasts with altered cell walls. Major alterations chiefly concerned the antigenic peptidomannans. Their amount in wall and their molecular weight were smaller in yeast grown with nystatin than in normal cultured yeast. Glucans and chitin were not seriously modified. Polymers requiring lipidic intermediates such as dolichol phosphate for their biosynthesis seemed to be most affected by the presence of nystatin.
