Abstract

Little is known about the relationship between C-reactive protein (CRP) and long-term mortality after acute myocardial infarction (AMI) in diabetic patients. The current study aimed to examine whether CRP levels are associated with for long-term all-cause, cardiovascular, and cardiac mortality in AMI patients with diabetes and those without separately. The cohort study included 663 diabetic and 1853 non-diabetic patients with AMI. The median follow-up time was 1045 days (2.9 years). According to the median concentration of serum CRP (8.95 mg/l), the patients were divided into two groups. The low CRP level group (<8.95 mg/l) served as a reference. In diabetic patients with AMI, the adjusted hazard ratios (HRs) for long-term all-cause, cardiovascular, and cardiac mortality were 1.62 (P = 0.027), 1.91 (P = 0.008), and 2.08 (P = 0.007), respectively. In non-diabetic patients with AMI, the adjusted hazard ratios (HRs) for long-term all-cause, cardiovascular, and cardiac mortality were 1.72 (P < 0.001), 1.8 (P < 0.001), and 1.78 (P = 0.001), respectively. Regardless of whether patients had diabetes or not, CRP value is an independent predictor of long-term, all-cause, cardiovascular, and cardiac mortality after AMI.

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. 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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
