Abstract

Subpartal and neonatal blood gas analyses have attracted increasing interest during the past 20 years. Different studies have been carried out to investigate the causes and immediate consequences of perinatal acidosis. It was the aim of this study to examine the long term outcome of acidotic-born babies. During 16 consecutive months all deliveries in the Obstetric Department of the Centre Hospitalier Universitaire Vaudois (CHUV) were investigated with regard to incidence and causes of a perinatal acidosis (pHa.umb. less than 7.15). The psycho-motor development of all acidotic newborns was followed up for an average of 15 months. Out of 1922 deliveries a blood sample was available in all but 11 cases (0.57%). Seven newborns were excluded from the study on the assumption that their acidosis and outcome might be related to the underlying condition (congenital malformation and infection, extreme prematurity) rather than perinatal events. From the remaining 1904 deliveries 6.4% (N = 121) had a pHa.umb. less than 7.15 (Tab. I). The incidence of certain perinatal factors was compared in the acidotic and the non acidotic groups (Tab. II). The percentage of acidotic newborns is significantly higher in primipareae, in deliveries done on ...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.

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.
