Maternity leave duration and adverse pregnancy outcomes: An international country-level comparison.

Aim: Preterm birth and low birthweight (LBW) lead to infant morbidity and mortality. The causes are unknown. This study evaluates the association between duration of maternity leave and birth outcomes at country level.

Auditory event-related potentials are related to cognition at preschool age after very preterm birth.

Background: Auditory event-related potentials (AERP) are neurophysiological correlates of sound perception and cognitive processes. Our aim was to study in very preterm born children at preschool age if AERP correlate with cognitive outcome.

Methods: Seventy children (mean ± SD gestational age 27.

A new penetration test method: protection efficiency of glove and clothing materials against diphenylmethane diisocyanate (MDI).

Reported cases of allergic contact dermatitis caused by methylenediphenyl diisocyanate (MDI) have increased and thereby increased the need for adequate skin protection. Current standardized permeation and penetration test methods give information about efficacy of protective materials against individual components of the polyurethane systems. They do not give information of what kind of clothing materials workers should wear against splashes when handling mixed MDI-polyurethane formulations, which contain MDI, its oligomers, and polyols.

Permeation tests of glove and clothing materials against sensitizing chemicals using diphenylmethane diisocyanate as an example.

Diphenylmethane diisocyanate (MDI) is a sensitizing chemical that can cause allergic contact dermatitis and asthma. Protective gloves and clothing are necessary to prevent skin exposure. Breakthrough times are used for the selection of chemical protective gloves and clothing.

A genome-wide association study of anorexia nervosa.

Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14 860 ancestrally matched controls as part of the Genetic Consortium for AN (GCAN) and the Wellcome Trust Case Control Consortium 3 (WTCCC3).
