Abstract

The clinical performance of the Copper T380A (TCu380A) and the Multiload 250 (MLCu250) intrauterine devices (IUDs) were evaluated for 12 months in a group of women who had one of the two IUDs inserted. Results are from a randomized clinical trial conducted at four collaborating research sites located in three developing countries. The gross cumulative life-table pregnancy rate of the TCu380A IUD was significantly lower than the rate with the MLCu250 IUD at 12 months (0.5 and 1.2, respectively, p < 0.01). No statistically significant differences between the two study IUDs were found with regard to IUD expulsion or IUD removal due to bleeding/pain, personal reasons, medical reasons, or planned pregnancy. TCu380A IUD users were more likely to report experiencing increased dysmenorrhea (p < 0.01) or intermenstrual pelvic pain (p < 0.01) than were MLCu250 IUD users. However, few of these users discontinued use of their assigned IUD because of having experienced menstrual bleeding disturbances or intermenstrual pelvic pain. These data indicate that the TCu380A IUD may be a better option than the MLCu250 IUD for women wishing to practice highly effective long-term birth control without having to resort to hormonal methods.

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.

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.

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.

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.

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.

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.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
