Safety and efficacy of platelet glycoprotein VI inhibition in acute ischaemic stroke (ACTIMIS): a randomised, double-blind, placebo-controlled, phase 1b/2a trial.

Background: Antagonists of glycoprotein VI-triggered platelet activation used in combination with recanalisation therapies are a promising therapeutic approach in acute ischaemic stroke. Glenzocimab is an antibody fragment that inhibits the action of platelet glycoprotein VI. We aimed to determine and assess the safety and efficacy of the optimal dose of glenzocimab in patients with acute ischaemic stroke eligible to receive alteplase with or without mechanical thrombectomy.

Predictive value of the TRI-SCORE for in-hospital mortality after redo isolated tricuspid valve surgery.

Objectives: The TRI-SCORE reliably predicts in-hospital mortality after isolated tricuspid valve surgery (ITVS) on native valve but has not been tested in the setting of redo interventions. We aimed to evaluate the predictive value of the TRI-SCORE for in-hospital mortality in patients with redo ITVS and to compare its accuracy with conventional surgical risk scores.

Methods: Using a mandatory administrative database, we identified all consecutive adult patients who underwent a redo ITVS at 12 French tertiary centres between 2007 and 2017.

Gut virome-colonising genus is associated with ulcerative colitis pathogenesis and induces intestinal inflammation .

Objectives: Ulcerative colitis (UC) is a chronic inflammatory disorder of unknown aetiology. Gut virome dysbiosis is fundamental in UC progression, although its role in the early phases of the disease is far from fully understood. Therefore, we sought to investigate the role of a virome-associated protein encoded by the genus, the hepatitis B virus X protein (HBx), in UC aetiopathogenesis.

Comparison of three antithrombotic strategies for emergent carotid stenting during stroke thrombectomy: a multicenter study.

Background: Periprocedural antithrombotic treatment is a key determinant for the risk-benefit balance of emergent carotid artery stenting (eCAS) during stroke thrombectomy. We aimed to assess the safety and efficacy of three types of antithrombotic treatment.

Methods: Retrospective review of prospectively collected endovascular databases in four comprehensive stroke centers, including consecutive cases of eCAS for tandem lesion strokes between January 2019 and July 2021.

Association of intravenous thrombolysis and pre-interventional reperfusion: a post hoc analysis of the SWIFT DIRECT trial.

Background: A potential benefit of intravenous thrombolysis (IVT) before mechanical thrombectomy (MT) is pre-interventional reperfusion. Currently, there are few data on the occurrence of pre-interventional reperfusion in patients randomized to IVT or no IVT before MT.

Methods: SWIFT DIRECT (Solitaire With the Intention For Thrombectomy Plus Intravenous t-PA vs DIRECT Solitaire Stent-retriever Thrombectomy in Acute Anterior Circulation Stroke) was a randomized controlled trial including acute ischemic stroke IVT eligible patients being directly admitted to a comprehensive stroke center, with allocation to IVT with MT versus MT alone.

Aspirin versus aggressive antiplatelet therapy for acute carotid stenting plus thrombectomy in tandem occlusions: ETIS Registry results.

Background: Patients treated with acute carotid stenting (CAS) may have higher odds of a favorable outcome than those treated without CAS during thrombectomy in tandem occlusions. Antiplatelet therapy is associated with CAS to avoid stent thrombosis, which occurs in around 20% of patients and negatively impacts outcomes. In this study we compared two antiplatelet strategies in tandem occlusion strokes treated with CAS and intracranial thrombectomy in clinical practice.

Safety and efficacy of intensive systolic blood pressure lowering after successful endovascular therapy: a post hoc analysis of the BP TARGET trial.

Background: The Safety and Efficacy of Intensive Blood Pressure Lowering after Successful Endovascular Therapy in Acute Ischaemic Stroke (BP TARGET) trial demonstrated no benefit from intensive systolic blood pressure (SBP) treatment after successful reperfusion with endovascular therapy. However, it remains unknown if the response to blood pressure treatment is modified by other factors.

Objective: To carry out a post hoc analysis of the BP TARGET trial data to determine if the response to blood pressure treatment is modified by factors such as age, history of hypertension, recanalization status, location of occlusion, diabetes, hyperglycemia, or pretreatment with intravenous thrombolysis.

Thrombectomy in basilar artery occlusions: impact of number of passes and futile reperfusion.

Background: The number of mechanical thrombectomy (MT) passes is strongly associated with angiographic reperfusion as well as clinical outcomes in patients with anterior circulation ischemic stroke. However, these associations have not been analyzed in patients with basilar artery occlusion (BAO). We investigated the influence of the number of MT passes on the degree of reperfusion and clinical outcomes, and compared outcome after ≤3 passes versus >3 passes.

Effect of intravenous thrombolysis before endovascular therapy on outcome according to collateral status: insight from the ETIS Registry.

Background: It is unknown whether collateral status modifies the effect of pretreatment intravenous thrombolysis (IVT) on the outcomes of patients with large vessel occlusions treated with endovascular therapy (EVT). We aimed to assess whether collateral status modifies the effect of IVT on the outcomes of EVT in clinical practice.

Methods: We used data from the ongoing prospective multicentric Endovascular Treatment in Ischemic Stroke (ETIS) Registry in France.

The LUCID study: living with ulcerative colitis; identifying the socioeconomic burden in Europe.

Background: Ulcerative colitis (UC) is an inflammatory bowel disease with increasing prevalence worldwide. Current treatment strategies place considerable economic and humanistic burdens on patients. The aim of this study was to determine the socioeconomic burden of UC in adult patients in European countries in a real-world setting.

Identifying patients with cerebral infarction within the time window compatible with reperfusion therapy, diagnostic performance of glutathione S-transferase-π (GST-π) and peroxiredoxin 1 (PRDX1): exploratory prospective multicentre study FLAG-1 protocol.

Introduction: Plasma biomarkers may be useful in diagnosing acute cerebral infarction requiring urgent reperfusion, but their performance remains to be confirmed. If confirmed, these molecules could be used to develop rapid and reliable decentralised measurement methods, making it possible to initiate reperfusion therapy before hospital admission. The FLAG-1 large prospective study will constitute a plasma bank to assess the diagnostic performance of two biomarkers: glutathione S-transferase-π and peroxiredoxin 1.

Collateral status reperfusion and outcomes after endovascular therapy: insight from the Endovascular Treatment in Ischemic Stroke (ETIS) Registry.

Background: Studies have suggested that collateral status modifies the effect of successful reperfusion on functional outcome after endovascular therapy (EVT). We aimed to assess the association between collateral status and EVT outcomes and to investigate whether collateral status modified the effect of successful reperfusion on EVT outcomes.

Methods: We used data from the ongoing, prospective, multicenter Endovascular Treatment in Ischemic Stroke (ETIS) Registry.

First-line thrombectomy strategy for anterior large vessel occlusions: results of the prospective ETIS egistry.

Background: The best recanalization strategy for mechanical thrombectomy (MT) remains unknown as no randomized controlled trial has simultaneously evaluated first-line stent retriever (SR) versus contact aspiration (CA) versus the combined approach (SR+CA).

Objective: To compare the efficacy and safety profiles of SR, CA, and SR+CA in patients with acute ischemic stroke (AIS) treated by MT.

Methods: We analyzed data of the Endovascular Treatment in Ischemic Stroke (ETIS) Registry, a prospective, multicenter, observational study of patients with AIS treated by MT.

Safety and efficacy of intra-arterial fibrinolytics as adjunct to mechanical thrombectomy: a systematic review and meta-analysis of observational data.

Background: Achieving the best possible reperfusion is a key determinant of clinical outcome after mechanical thrombectomy (MT). However, data on the safety and efficacy of intra-arterial (IA) fibrinolytics as an adjunct to MT with the intention to improve reperfusion are sparse.

Methods: We performed a PROSPERO-registered (CRD42020149124) systematic review and meta-analysis accessing MEDLINE, PubMed, and Embase from January 1, 2000 to January 1, 2020.

Clot Burden Score and Collateral Status and Their Impact on Functional Outcome in Acute Ischemic Stroke.

Background And Purpose: Collateral status and thrombus length have been independently associated with functional outcome in patients with acute ischemic stroke. It has been suggested that thrombus length would influence functional outcome via interaction with the collateral circulation. We investigated the individual and combined effects of thrombus length assessed by the clot burden score and collateral status assessed by a FLAIR vascular hyperintensity-ASPECTS rating system on functional outcome (mRS).

Direct aspiration stroke thrombectomy: a comprehensive review.

Mechanical thrombectomy is now the standard of care for acute ischemic stroke patients with large vessel occlusions, and can be performed with several devices and techniques. One of these techniques, direct aspiration (DA), consists of navigating a large-bore catheter up to the face of the clot and initiating forceful suction. This comprehensive review has three objectives: (1) to describe the direct aspiration technique; (2) to present the available evidence regarding predictive factors of DA success and performance compared with other techniques; and (3) to discuss the forthcoming improvements in distal aspiration.

Local anesthesia versus general anesthesia during endovascular therapy for acute stroke: a propensity score analysis.

Background: To date, the choice of optimal anesthetic management during endovascular therapy (EVT) of acute ischemic stroke patients remains subject to debate. We aimed to compare functional outcomes and complication rates of EVT according to the first-line anesthetic management in two comprehensive stroke centers: local anesthesia (LA) versus general anesthesia (GA).

Methods: Retrospective analysis of prospectively collected databases, identifying all consecutive EVT for strokes in the anterior circulation performed between January 1, 2018 and December 31, 2018 in two EVT-capable stroke centers.

Addition of azathioprine to the switch of anti-TNF in patients with IBD in clinical relapse with undetectable anti-TNF trough levels and antidrug antibodies: a prospective randomised trial.

Objectives: In patients with IBD experiencing an immune-mediated loss of response (LOR) to antitumour necrosis factor (anti-TNF), algorithms recommend a switch of anti-TNF without immunosuppressive drug. The aim of our study was to compare in these patients two strategies: either switch to a second anti-TNF alone or with addition of azathioprine (AZA). After randomisation outcomes (time to clinical and pharmacokinetic failure) were compared between the two groups during a 2-year follow-up period.

Blood pressure reduction and outcome after endovascular therapy with successful reperfusion: a multicenter study.

Background: Elevated systolic blood pressure (SBP) after mechanical thrombectomy (MT) correlates with worse outcome. However, the association between SBP reduction (SBPr) and outcome after successful reperfusion with MT is not well established.

Objective: To investigate the association between SBPr in the first 24 hours after successful reperfusion and the functional and safety outcomes of MT.
