Article Synopsis
- Portable low-field magnetic resonance imaging (LF-MRI) offers a promising way to assess Alzheimer's disease (AD) patients in places where traditional MRI isn't available, despite some limitations in image quality.
- * Researchers optimized LF-MRI techniques and created a free machine learning tool for analyzing brain structure and white matter changes in patients with cognitive impairments.
- * The study found that LF-MRI accurately measures hippocampal volumes and white matter hyperintensities, suggesting that this technology can improve access to neuroimaging for dementia patients at a lower cost.
Article Synopsis
- Cognitive motor dissociation (CMD) involves patients who can follow commands in brain scans like fMRI, despite showing no behavioral signs of language function, highlighting the importance of accurate diagnosis in severe brain injuries.
- Recent findings outline a structured approach for assessing CMD at clinical institutions, underlining the need for ethical considerations, standardized protocols, and effective communication of results.
- The proposed method for CMD assessment aims to be adaptable, allowing for updates and improvements as more evidence becomes available in the field.
Background: Colorectal carcinoma (CRC) is one of the most frequently diagnosed forms of cancer worldwide. The (, ) and genes encode proteins that are important therapeutic targets for the treatment of CRC and, together with the mismatch repair (MMR) system, are closely related to patient prognosis and survival in advanced CRC. Here we evaluate the mutational profile and the frequency of mutations in the , and genes, along with the expression of MMR in advanced CRC, at a tertiary hospital in southern Brazil.

View Article and Find Full Text PDFUrticaria and angioedema are caused by immunoglobulin E- and non-immunoglobulin E-mediated release of histamine and other inflammatory mediators from mast cells and basophils. Diagnosis is made clinically, and anaphylaxis must be ruled out if urticaria or angioedema is present. A limited nonspecific laboratory workup should be considered unless elements of the history or physical examination suggest specific underlying conditions.
