Abstract

The relationship between serum uric acid (SUA) levels and stroke is controversial. The discrepancies in the results could be due to the uneven setting of comorbidity. It is known that hyperuricaemia increases in parallel with the decline in renal function; however, there are few studies that adjust for renal disease. To investigate the relationship between SUA levels in the acute phase of ischaemic stroke according to the presence or absence of chronic kidney disease and clinical outcomes during admission. Retrospective cross-sectional analysis of patients recruited through a unicentric stroke registry. The sample was divided according to its quartiles of SUA. Renal disease was defined based on the haematocrit, urea and Gender (HUGE) formula. The outcome was determined by the National Institutes of Health Stroke Scale (NIHSS) score. Statistically robust methods were used with R (version 3.3.2). A total of 412 patients (53.8% male) were analysed. The NIHSS score decreased as the SUA levels increased (p < 0.0009). Robust linear regression analysis showed a significant association between quantitative SUA levels and NIHSS score (p < 0.0003), even when patients were categorized according to renal function (p < 0.05). In an adjusted...Continue Reading

COVID-19

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.
