Cigarette smoking in pregnancy: differences in peripheral circulation between smokers and non-smokers.

British Journal of Obstetrics and Gynaecology
H Ashton

Abstract

Ten smokers and ten non-smokers were followed serially from 12 to 16 weeks of pregnancy to six weeks postnatally. Measurements of calf and foot blood flow and toe and finger skin temperature were made at 4 to 6 week intervals in both groups, and the acute effects on the peripheral circulation of smoking one standard cigarette were also measured in the smokers at each stage of pregnancy. Comparison between the smokers and non-smokers showed that in the last trimester of pregnancy smokers had significantly higher foot blood flow and toe and finger temperature than non-smokers. These circulatory variables rose during the period of pregnancy studied in smokers but altered little in non-smokers. There was no significant difference in calf blood flow between the groups. Smoking a cigarette during pregnancy caused a fall in foot blood flow and in finger and toe skin temperature. Smoking increased calf blood flow between 12 and 25 weeks of pregnancy but decreased it in late pregnancy. Previous investigations of blood flow in pregnancy have not differentiated between smokers and non-smokers. It is suggested that the rise in foot blood flow and skin temperature believed to occur generally during pregnancy applies mainly to smokers. Some ...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.
