Renal impairment on clinical outcomes following endovascular recanalization

Lulu XiaoACTUAL Investigators


To determine the influence of renal impairment (RI) on clinical outcomes at 3 months and the risk of recurrent stroke in patients presenting with emergent large vessel occlusion (ELVO) treated with emergent endovascular treatment (EVT). Consecutive patients with anterior circulation stroke due to ELVO treated with EVT in 21 endovascular centers were included. Multivariate regressions were used to evaluate the association of RI with mortality, functional independence (modified Rankin Scale [mRS] score 0-2), and functional improvement (shift in mRS score) at 3 months. The association between RI and the risk of recurrent stroke was evaluated with multivariate competing-risk regression analyses. A total of 628 patients with ELVO (mean age 64.7 ± 12.5 years, median NIH Stroke Scale score 17 points, 99 [15.8%] with RI) who underwent EVT were enrolled. After adjustment for other relevant variables, multivariate regression analysis indicated that RI was independently associated with functional independence (adjusted odds ratio 0.53, 95% confidence interval [CI] 0.29-0.96, p = 0.035) at 3 months but not with mortality or functional improvement. Multivariate competing-risk regression analysis showed that patients with RI who received EVT...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Social Learning

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
