Abstract

To describe the status and characteristics of under-reporting of death cases within national disease surveillance system (DSPs). Six villages (communities) were selected in each of the 161 counties of DSPs by multi-stage random cluster sampling methods, the information of resident from 2006 to 2008 was collected, and a survey of the under-reporting deaths cases was carried out which covered 6 422 667 people in all. The under-reporting rate was estimated by ages, genders and regions. The mortality was compared before and after the adjustment of the under-reporting rate. The total crude rate of under-reporting of whole nation was 16.68% (6271/37 603), and after the adjustment by weight the rate was 17.44%; the under-reporting rate of urban areas was a bit lower than rural areas, which were 16.08% and 18.14% respectively (P < 0.01); the under-reporting rate of middle and west regions were higher than the east, which were 19.27%, 18.15% and 15.46% respectively (P < 0.01). The under-reporting rate of children of under-five years old was much higher than that of people of five and above-five years old, which were 34.95% and 16.90% respectively (P < 0.01). The gender difference was especially obvious in age group 0-4, for women 39.36%...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.
