Selective serotonin reuptake inhibitors (SSRIs) and breast cancer : a record linkage study
(2008-01-09)Evidence suggests that selective serotonin reuptake inhibitors (SSRIs, a class of antidepressant medications) may contribute to increased breast cancer risk by stimulating the secretion of prolactin, a potential tumour ... -
School and neighbourhood recreational environments and their impact on physical activity participation among Canadian youth
(2008-05-27)Background: Less than half of Canadian youth meet recommended levels of physical activity. This is of concern given the health burden associated with physical inactivity. With the limited success of physical activity ... -
Determinants and methods of assessment of melatonin levels among rotating shift nurses
(2008-06-30)Background: Long-term night shift work has been associated with multiple cancer sites, including breast, prostate, colon and endometrial. The mechanism for this effect is hypothesized to include the hormone melatonin; where ... -
Identifying responders to melphalan and dexamethasone for newly diagnosed multiple myeloma patients
(2008-07-22)Background: MY7 clinical trial compared dexamethasone plus melphalan (MD) vs. prednisone plus melphalan (MP) in multiple myeloma treatment and found no statistically significant difference in overall survival (OS) between ... -
Influence of polymorphisms in the thymidylate synthase gene on plasma homocysteine concentration
(2008-08-22)Background: Significant interest in homocysteine exists due to its established role in embryogenesis, cardiovascular disease and neurotoxicity. This research investigates total plasma homocysteine in the context of ... -
