Abstract

To examine higher order multiple pregnancy and birth rates in NSW, and to describe trends in the characteristics and management of these births. Cross-sectional analytic study. New South Wales, Australia. Two hundred and ninety-one women who gave birth to triplets, quadruplets or quintuplets (880 babies) from 1 January 1990 to 31 December 1999. Data were obtained from the NSW Midwives Data Collection and rates over time were calculated. Higher order multiple birth and pregnancy rates (> or = 20 weeks), place of birth, mode of delivery, fetal death rates and Apgar scores. There was no significant change in the number or rate of higher order multiple births in NSW during the 1990s with an average annual rate of 10.3/10,000 births or 3.5/10,000 pregnancies > or = 20 weeks. Among women with higher order multiple pregnancies, those aged > or = 35 years increased from 19% in 1990 to 47% in 1999. There was also a trend towards delivery in a perinatal centre from 56% to 70%, and vaginal birth from 18% to 28%. There were no significant changes in infant outcomes. The increases in higher order multiple pregnancies observed in Australia in the 1980s, and into the 1990s in other countries, have not persisted in NSW, suggesting that guideli...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.
