Unlocking the diagnosis of depression in primary care: Which key symptoms are GPs using to determine diagnosis and severity?

Objective: Diagnosing depression in primary care settings is challenging. Patients are more likely to present with somatic symptoms, and typically with mild depression. Use of assessment scales is variable.

Severity alone should no longer determine therapeutic choice in the management of depression in primary care: findings from a survey of general practitioners.

Background: The treatment of depression in primary care remains suboptimal for reasons that are complex and multifactorial. Typically GPs have to make difficult decisions in limited time and therefore, the aim of this study was to examine the management of depression of varying severity and the factors associated with treatment choices.

Method: Nested within a primary care educational initiative we conducted a survey of 1760 GPs.

A role for cyclooxygenase in aging-related changes of beta-adrenoceptor-mediated relaxation in rat aortas.

beta-Adrenoceptor-mediated vasorelaxation decreases with age in various vascular beds. The present study investigated the roles of cyclooxygenase (COX) on beta-adrenoceptor vasorelaxation by isoprenaline in 8- and 54-week-old rat aortas. The vasorelaxation responses by isoprenaline (0.

Endogenous nitric oxide attenuates beta-adrenoceptor-mediated relaxation in rat aorta.

1. Divergent evidence suggests that the intracellular signalling pathways for beta-adrenoceptor-mediated vascular relaxation involves either cAMP/protein kinase (PK) A or endothelial nitric oxide (NO) release and subsequent activation of cGMP/PKG. The present study identifies the relative roles of NO and cAMP, as well as dependence on the endothelium for beta-adrenoceptor-mediated relaxation of rat isolated aortas.

Age-related changes in monocyte and platelet cyclooxygenase expression in healthy male humans and rats.

Cyclooxygenase (COX) catalyses the formation of prostanoids that are crucial in maintaining hemostasis and important in inflammation. Animal studies reveal that COX-1 and COX-2 expression increase in some cell types during aging. This study determined age-related changes in COX expression in platelets and monocytes.
