The results of a retrospective study involving 622 twin-pairs born over an 18-month period among 17,726 births at the University of Ilorin Teaching Hospital, Ilorin, Nigeria, are presented with particular reference to four variables: birthweight, presentation, parity, and intertwin delivery time interval. The twinning incidence was 35.1 per 1000. Monozygous and dizygous rates are 7 and 28 per 1000, respectively. Overall perinatal mortality (PNM) was 15.5%. Mortality was higher in second than in first twin (19.5% vs. 11.6%), and consistently higher when divided into birthweight groups. Corrected PNM increased with breech presentations: 16.3% in breech:breech compared with 3.9% in vertex:vertex presentations. The twinning rate increased with parity; PNM is low in parity 1, of little variation in birth-ranks 2-5, and high in para 6 and above. Delivery of the second twin within 15 min seems optimal, giving a corrected PNM 3.6% in contrast to rates of 10.1%, 14.0% and 19.1%, respectively when delivery occurred between 16 and 30, 31 and 60 and greater than 60 min, respectively. Prevention of preterm delivery, increased use of cesarean section delivery for malpresentation, active management of delivery of second twin within an optimal...Continue Reading

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
