Fetal response to periodic sleep apnea: a new syndrome in obstetrics

European Journal of Obstetrics, Gynecology, and Reproductive Biology
S J Joel-Cohen, A Schoenfeld

Abstract

Periodic sleep apnea, a chronic sleep deprivation state, in which marked changes in the arterial PO2 and PCO2 tensions have been recorded, is a relatively new syndrome not previously reported in pregnancy. It is characterized by episodes of apnea, prevalently obstructive, during sleep. The majority of patients with this syndrome have snored heavily for years, suggesting a causal relationship between snoring and periodic sleep apnea. The effects of prolonged snoring on alveolar ventilation and systemic pressure(s) suggest that this snoring has physiopathological implications on maternal cardio-respiratory reserve and indirectly upon the fetus, especially as there are recordable changes in fetal heart rate and also a change in the acid-base status of the fetus. The possibility that this syndrome may have an adverse effect upon the fetus is stressed.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. 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.
