Background: Among the currently approved antiobesity medications, the glucagon-like-peptide-1 receptor-agonists (GLP-1 RAs) liraglutide and semaglutide, and the dual glucose-dependent-insulinotropic-polypeptide (GIP)/GLP-1 RA tirzepatide have been suggested to reduce cardiovascular-risk in overweight or obesity without diabetes. Objectives: The objective of this study was to evaluate the cardio- and neuroprotective potential of these novel agents in the nondiabetic overweight/obese adult population. Data sources and methods: A systematic review and meta-analysis of randomized-controlled clinical trials (RCTs) was performed to estimate the risk of major adverse cardiovascular events (MACE), all-cause and cardiovascular mortality in overweight or obese adults without diabetes treated with GLP-1 or GIP/GLP-1 RAs (vs placebo). Secondary outcomes included the risk of myocardial infarction (MI) and stroke. Results: Sixteen RCTs (13 and 3 on GLP-1 RAs and tirzepatide, respectively) comprising 28,168 participants were included. GLP-1 or GIP/GLP-1 RAs reduced MACE (odds ratio (OR): 0.79; 95% confidence interval (CI): 0.71–0.89; p

Background and aims: To investigate whether stroke aetiology affects outcome in patients with acute ischaemic stroke who undergo endovascular therapy. Methods: We retrospectively analysed patients from the Bernese Stroke Centre Registry (January 2010–September 2018), with acute large vessel occlusion in the anterior circulation due to cardioembolism or large-artery atherosclerosis, treated with endovascular therapy (±intravenous thrombolysis). Results: The study included 850 patients (median age 77.4 years, 49.3% female, 80.1% with cardioembolism). Compared with those with large-artery atherosclerosis, patients with cardioembolism were older, more often female, and more likely to have a history of hypercholesterolaemia, atrial fibrillation, current smoking (each p

Endovascular thrombectomy (EVT) has become standard of care for large vessel occlusion strokes but current guidelines exclude a large proportion of patients from this highly effective treatment. This review therefore focuses on expanding indications for EVT in several borderline indications such as patients in the extended time window, patients with extensive signs of infarction on admission imaging, elderly patients and patients with pre-existing deficits. It also discusses the current knowledge on intravenous thrombolysis as an adjunct to EVT and EVT as primary therapy for distal vessel occlusions, for tandem occlusions, for basilar artery occlusions and in pediatric patients. We provide clear recommendations based on current guidelines and further literature.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China and rapidly spread worldwide, with a vast majority of confirmed cases presenting with respiratory symptoms. Potential neurological manifestations and their pathophysiological mechanisms have not been thoroughly established. In this narrative review, we sought to present the neurological manifestations associated with coronavirus disease 2019 (COVID-19). Case reports, case series, editorials, reviews, case-control and cohort studies were evaluated, and relevant information was abstracted. Various reports of neurological manifestations of previous coronavirus epidemics provide a roadmap regarding potential neurological complications of COVID-19, due to many shared characteristics between these viruses and SARS-CoV-2. Studies from the current pandemic are accumulating and report COVID-19 patients presenting with dizziness, headache, myalgias, hypogeusia and hyposmia, but also with more serious manifestations including polyneuropathy, myositis, cerebrovascular diseases, encephalitis and encephalopathy. However, discrimination between causal relationship and incidental comorbidity is often difficult. Severe COVID-19 shares common risk factors with cerebrovascular diseases, and it is currently unclear whether the infection per se represents an independent stroke risk factor. Regardless of any direct or indirect neurological manifestations, the COVID-19 pandemic has a huge impact on the management of neurological patients, whether infected or not. In particular, the majority of stroke services worldwide have been negatively influenced in terms of care delivery and fear to access healthcare services. The effect on healthcare quality in the field of other neurological diseases is additionally evaluated.

Background and purpose: In acute ischaemic stroke (AIS) of the anterior circulation (AC) treated with mechanical thrombectomy (MT), data point to a decline of treatment effect with increasing time from symptom onset to treatment. However, the magnitude of the decline will depend on the clinical setting and imaging selection used. The aims of this study were (1) to evaluate the clinical effect of time to reperfusion (TTR); and (2) to assess the safety and technical efficacy of MT according to strata of TTR. Methods: Using the retrospective multicentre BEYOND-SWIFT registry data (ClinicalTrials.gov identifier: NCT03496064), we compared safety and efficacy of MT in 1461 patients between TTR strata of 0–180 min ( n = 192), 180–360 min ( n = 876) and >360 min ( n = 393). Clinical effect of TTR was evaluated using multivariable logistic regression analyses adjusting for pre-specified confounders [adjusted odds ratios (aOR) and 95% confidence intervals (95% CI)]. Primary outcome was good functional outcome (modified Rankin Scale: mRS 0–2) at day 90. Results: Every hour delay in TTR was a significant factor related to mRS 0–2 (aOR 0.933, 95% CI 0.887–0.981) with an estimated 1.5% decreased probability of good functional outcome per hour delay of reperfusion, and mRS 0–1 (aOR 0.929, 95% CI 0.877–0.985). Patients with late TTR had lower rates of successful and excellent reperfusion, higher complication rates and number of passes. Conclusions: TTR is an independent factor related to long-term functional outcome. With increasing TTR, interventional procedures become technically less effective. Efforts should be made to shorten TTR through optimized prehospital and in-hospital pathways.
