Journal ArticleDOI
Plasma cytokine profiles in depressed patients who fail to respond to selective serotonin reuptake inhibitor therapy
TL;DR: Suppression of proinflammatory cytokines does not occur in depressed patients who fail to respond to SSRIs and is necessary for clinical recovery.
Journal ArticleDOI
Prolactin and dopamine: What is the connection? A Review Article
TL;DR: All typical antipsychotic medications are associated with sustained hyperprolactinaemia due to their high affinity for the D2 receptor and their slow dissociation from the receptor once bound, but atypicals differ quite dramatically in their propensity to cause prolonged high prolactin levels.
Journal ArticleDOI
Tryptophan degradation in irritable bowel syndrome: evidence of indoleamine 2,3-dioxygenase activation in a male cohort
Gerard Clarke,Peter Fitzgerald,John F. Cryan,Eugene M. Cassidy,Eamonn Martin Quigley,Timothy G. Dinan +5 more
TL;DR: Novel evidence is provided for an immune-mediated degradation of tryptophan in a male IBS population and the kynurenine pathway is identified as a potential source of biomarkers in this debilitating condition.
Journal ArticleDOI
Impact of gender and menstrual cycle phase on plasma cytokine concentrations.
TL;DR: The normal menstrual cycle is associated with increased production of sIL-6R, IL-4 and TNF-α in the luteal phase compared to the early follicular phase, and Females were found to have significantly higher concentrations of TNFs across all phases of the menstrual cycle, compared to males across similar time points.

TL;DR: The guidance contained in this article is not intended to replace national guidance, however, it does provide additional detail that is unlikely to be covered in existing guidelines, and focuses on areas of uncertainty and disagreement.
