Abstract

To describe temporal trends of preterm birth subtypes, neonatal morbidity, and hospital neonatal mortality. A database of 1.7 million births that occurred in 51 maternity hospitals in Latin America from 1985 to 2003 was studied. Subgroups of preterm births were classified according to the presence or absence of maternal medical or obstetric complications, spontaneous labor, preterm labor after premature rupture of membranes, induction of labor, or elective cesarean. Outcomes studied, for different periods, were prevalence of small for gestational age, neonatal morbidity, and neonatal mortality. Spontaneous preterm labor without maternal complications was the most frequent subtype of preterm birth (60%), followed by premature rupture of membranes without maternal complications. Preterm births due to elective induction and delivery by elective cesarean increased markedly in the last 20 years, from 10% in 1985-1990 to 18.5% in recent years. Neonates born after spontaneous labor without maternal complications had the lowest mortality rate, but their large numbers made them responsible for one half of the preterm mortality. The induction followed by elective cesarean subgroups accounted for 13.4% of the preterm deaths between 1985 a...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.
