Associations Between Asthma and Sensitization to Pet or Pollen Allergens in Young Swedish Twins - The STOPPA Study.

Background: An association between childhood asthma and IgE sensitization has been established, but our understanding of the genetic and environmental contribution to it is incomplete. Our aim was to estimate the associations and dose-response relationship between asthma and sensitization to airborne allergens in Swedish 9- to 14-year-old twins. Additionally, we aimed to explore the importance of familial confounding from shared genes and environment using co-twin controls.

Long-term follow-up of a randomized study of support group intervention in women with primary breast cancer.

Background: Despite a fairly good prognosis, many breast-cancer patients suffer from symptoms such as anxiety, depression and fatigue, which may affect health-related quality of life and may persist for several years. The aim of the present study was to perform a long-term follow-up of a randomized study of support group intervention in women after primary breast cancer treatment.

Materials And Methods: Three hundred and eighty two women with primary breast cancer were randomized to support group intervention or control group, 181 in each group.

A randomized controlled trial of support group intervention after breast cancer treatment: results on sick leave, health care utilization and health economy.

Background: More than 50% of breast cancer patients are diagnosed before the age of 65. Returning to work after treatment is, therefore, of interest for both the individual and society. The aim was to study the effect of support group intervention on sick leave and health care utilization in economic terms.

A randomized controlled trial of a support group intervention on the quality of life and fatigue in women after primary treatment for early breast cancer.

Background: When diagnosed with breast cancer, most women's lives change as well as their perspectives on and appreciation of life. The aim of the present study was to evaluate whether psychosocial support intervention could influence health-related quality of life (HRQOL) and fatigue during the first year after diagnosis.

Material And Methods: Of 382 patients with newly diagnosed breast cancer, 191 patients were randomized to an intervention group and 191 patients were randomized to a routine control group.
