Ambient air pollution and emergency department visits and hospitalisation for cardiac arrest: a population-based case-crossover study in Reykjavik, Iceland.

Objectives: To assess the association between traffic-related ambient air pollution and emergency hospital visits for cardiac arrest.

Design: Case-crossover design was used with a lag time to 4 days.

Setting: The Reykjavik capital area and the study population was the inhabitants 18 years and older identified by encrypted personal identification numbers and zip codes.

Ambient nitrogen dioxide is associated with emergency hospital visits for atrial fibrillation: a population-based case-crossover study in Reykjavik, Iceland.

Background: In Iceland air quality is generally good; however, previous studies indicate that there is an association between air pollution in Reykjavik and adverse health effects as measured by dispensing of medications, mortality, and increase in health care utilisation. The aim was to study the association between traffic-related ambient air pollution in the Reykjavik capital area and emergency hospital visits for heart diseases and particularly atrial fibrillation and flutter (AF).

Methods: A multivariate time-stratified case-crossover design was used to study the association.

Hydrogen sulfide and traffic-related air pollutants in association with increased mortality: a case-crossover study in Reykjavik, Iceland.

Objectives: To study the association between daily mortality and short-term increases in air pollutants, both traffic-related and the geothermal source-specific hydrogen sulfide (H₂S).

Design: Population-based, time stratified case-crossover. A lag time to 4 days was considered.

Evaluation of the clinical effect of an on-line course for community nurses on post-partum emotional distress: a community-based longitudinal time-series quasi-experiment.

About 14% of Icelandic women suffer post-partum from frequent depressive symptoms, and of those, 12% also report a high degree of parenting stress. Education of nurses and midwives on post-partum distress is crucial in reducing its degree. The purpose of the study is to evaluate the clinical effect of an on-line course for community nurses on post-partum emotional distress.
