Lifelong versus not lifelong death wishes in older adults without severe illness: a cross-sectional survey.

Background: Some older adults with a persistent death wish without being severely ill report having had a death wish their whole lives (lifelong persistent death wish; L-PDW). Differentiating them from older adults without severe illness who developed a death wish later in life (persistent death wish, not lifelong; NL-PDW) can be relevant for the provision of adequate help and support. This study aims to gain insight into the characteristics, experiences, and needs of older adults with a L-PDW versus older adults with a NL-PDW and into the nature of their death wishes.

EPA and DHA as markers of nutraceutical treatment response in major depressive disorder.

Purpose: Depression clinical trials are increasingly studying biomarkers to predict and monitor response to treatment. Assessment of biomarkers may reveal subsets of patients who are responsive to nutraceutical treatment, which may facilitate a personalized approach to treating depression.

Methods: This is a post hoc analysis of an 8-week, double-blind, randomized, controlled trial (n = 158) investigating a combination nutraceutical comprising Omega-3 (EPA 1 g/DHA 656 mg), SAMe, zinc, 5-HTP, folinic acid, and co-factors versus placebo for the treatment of Major Depressive Disorder.

Nutrient and genetic biomarkers of nutraceutical treatment response in mood and psychotic disorders: a systematic review.

Nutrient and genetic biomarkers in nutraceutical trials may allow for the personalisation of nutraceutical treatment and assist in predicting treatment response. We aimed to synthesise the findings of trials which have included these biomarkers to determine which may be most useful for predicting nutraceutical response in mood and psychotic disorders. A systematic review was conducted assessing available literature concerning nutraceutical clinical trials in mood and psychotic disorders (major depression, bipolar disorder, schizophrenia) with baseline and endpoint blood nutrient markers or genetic data available.
