Abstract

The aim of the study was to describe differences in life style variables according to socioeconomic groupings and to analyse the association between birth weight, stillbirth and congenital malformations according to the socioeconomic groupings for the father as well as the mother. It was conducted as a follow-up of 11,888 pregnant women in Odense and Aalborg, Denmark who were consecutively enrolled in the study from April 1984 to April 1987 as part of a community trial. Consecutively information regarding socioeconomic group and life-style factors were collected by means of self-administered questionnaires in the 36th week of gestation. Data on pregnancy outcomes were collected from birth certificates and medical records according to standardized search routines. It was found that women in the lower socioeconomic groups were younger, smaller, had a higher prepregnancy weight, smoked more and had a higher intake of coffee during pregnancy than women in higher socioeconomic groups. Better off women, on the other hand, had a higher consumption of alcohol, fish, and vegetables. Low birth weight was found to be negatively correlated to socioeconomic grouping. The lowest birth weights were found among babies born to unskilled and une...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.

Landau-Kleffner Syndrome

Landau Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder, is a rare childhood neurological syndrome characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electroencephalogram. Discover the latest research on LKS 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.

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.
