Abstract

This study evaluated 3rd generation human immunodeficiency virus (HIV) test patterns and HIV infection rates in the United States Air Force (USAF). Retrospective database study. HIV enzyme-linked immunoassay (ELISA) and Western blot tests were analysed for all USAF personnel from 2008 to 2012. For new HIV cases, unadjusted and adjusted annual rates were calculated per 100,000 persons. In total, 1,608,665 tests were performed in 626,298 individuals, with a reactive ELISA observed in 809 (0.001%) persons. Western blot (n = 1949) results included 378 (19.4%) positive, 1283 (65.8%) negative, and 288 (15.0%) indeterminate (WBi). Unadjusted annual HIV rates were between 16.7 and 20.6 per 100,000 persons during the study period. The overall age-adjusted rate was 14.8 cases per 100,000 persons tested. Blacks/African Americans had the highest risk of HIV (risk ratio 7.9 [95% confidence interval 5.78, 9.95] compared to Whites). WBi results, which can cause delays in determining HIV status, were relatively common with the 3rd generation assay. However, this will be mitigated by a planned transition to a 4th generation assay. Although the overall rate of HIV in the USAF is lower than US civilian adults, HIV prevention efforts targeting you...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.
