Classifying mild cognitive impairment and Alzheimer's disease by constructing a 14-gene diagnostic model.

Background: Alzheimer's disease (AD) and mild cognitive impairment (MCI) are two neurodegenerative diseases. Most patients with MCI will develop AD. Early detection of AD and MCI is a crucial issue in terms of secondary prevention.

Synchronous colorectal cancer and multiple myeloma with chest wall involvement: Is this a coincidence?

Multiple primary malignant neoplasms (MPMNs) are rare malignant neoplasms that simultaneously or successively occur in the same patient as 2 or more primary malignancies. Currently, an increasing number of cases are being reported. In general, MPMNs more commonly occur as 2 solid tumors or 2 hematological malignancies.

Red blood cell distribution width and ischaemic stroke.

The red blood cell distribution width (RDW) is a measure of red blood cell (RBC) size heterogeneity, which is easily calculated by dividing the SD of erythrocyte volumes for the mean corpuscular volume. Recent reporter suggested that, besides haematological diseases and anaemia, many human disorders may be closely associated with the elevated RDW. A literature review has revealed the RDW may be closely related to the development of ischaemic stroke, carotid artery atherosclerosis and cerebral embolism.
