Abstract

Varicella virus can cause two different diseases: chickenpox and herpes zoster. In 2005 varicella vaccine has been introduced in the Spanish national vaccination schedule for 10-14 years old non-immune people, in order to reduce the severity of the disease. In 2007 a new surveillance protocol with aggregate data for chickenpox and herpes zoster was approved in order to detect any change in age distribution, severity and complications of the chickenpox and herpes zoster cases. The aim of this study is to know the burden of diseases (in the last ten years). Number of cases, hospitalization and incidence for chickenpox and herpes zoster were study for two periods 1997-2003 and 2005-2007. Analysis for 1996-2007 fatal cases was done too. We decided to remove year 2004 because the extremely high chickenpox incidence registered. RENAVE (Spanish Surveillance Network), Spanish hospital surveillance system (CMBD), and mortality registries. Chickenpox incidence decreased since 2005, but an increasing trend was detected in hospitalisation with an average of 1,311 hospitalizations every year. For the 32%-36% of hospitalized cases, the main diagnosis was not chickenpox. 4-14 deaths per year have been detected; 80% of them were older than 14 ...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.
