Abstract

Obstetric anal sphincter injuries (OASISs) are a devastating postpartum complication; reducing rates is paramount to improving quality of care. In Norway, implementation of a perineal protection program decreased the incidence of OASIS by 48%. We sought to assess impact on OASIS rates following a similar program. This institutional review board-approved, retrospective cohort study was performed in an academic hospital system. The periods of analysis were November 2014 through October 2015 for the preintervention arm and November 2015 through October 2016 for the postintervention arm. From November 2 to 6, 2015, 2 Norwegian experts conducted a didactic and hands-on, on-site workshop focusing on perineal protection. The experts were then present on labor and delivery wards to reinforce perineal protection in live deliveries. Teachings were emphasized at departmental meetings for the remainder of the year. Data were extracted from electronic medical records and manually audited. The rate of vaginal delivery was similar among both periods (6504 and 6650; P = 0.059). Obstetric anal sphincter injury rates decreased from 211 (3.2%) preintervention to 189 (2.8%) after the workshop. Although this represented 32 fewer injuries, it was no...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.
