Abstract

To observe the changes of hospitalization rates and in-hospital mortality for coronary heart disease (CHD) in Beijing from 2007-2012. Patients hospitalized for CHD in Beijing from 1 January 2007 to 31 December 2012 were identified from"The Cardiovascular Disease Surveillance System in Beijing". In total, 421 929 patients aged ≥25 years of permanent Beijing residents were admitted for CHD in Beijing during the 6 years. After excluding duplicate records and validation for the completeness and accuracy of the records, the hospitalization rates for CHD and in-hospital CHD mortality were analyzed. Trends in hospitalization rates and the in-hospital mortality for CHD were analyzed with Poisson regression models. The age-standardized average hospitalization rate of CHD was 515.3 per 100 000 population in patients aged ≥25 years in Beijing. During the six years, an increasing trend was observed in the hospitalization rates for CHD after adjusting the age and gender (P<0.001). The age-standardized hospitalization rates of CHD increased by 43.0% in the past six years. The greatest increases of hospitalization rates were noted in both men and women between 45 to 54 years. The age-standardized in-hospital mortality decreased from 3.3% to 2...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.

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. Discover the latest research on molecular barcoding here.

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.

Evolution of Pluripotency

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
