Abstract

With recent advances in neonatal medicine, the risk of mortality for premature newborns has been markedly reduced. Attention has shifted to the morbidity associated with preterm delivery. Consideration of anticipated neonatal morbidity at a particular gestational age plays an important part in the decision of whether or not to treat preterm labor. We have assessed eight indices of short-term morbidity in 170 liveborn infants delivered between 26 and 35 completed weeks of gestation and calculated the gestational age-specific rates of each measure of morbidity. Five measures of short-term morbidity were significantly reduced by extending the gestation from 34 to 35 weeks. To illustrate the effect of prolonged pregnancy on the incidence of short-term neonatal morbidity, the actual incidence of morbidity from a group of preterm labor patients who were part of a preterm birth prevention program was compared to the anticipated incidence of these same morbidity factors has birth occurred when preterm labor was first diagnosed. There was a significant decrease in the number of observed, as opposed to anticipated, neonatal deaths and in morbidity occurrences in four of the six factors tested. Implications for considering short-term neon...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.
