To investigate the association between suicide death and serum cholesterol levels as measured at times close to suicide death.

We conducted a nested case-control study of 41 cases of suicide deaths and 205 matched controls with serum total cholesterol (TC) levels till 3 years before suicide death in a large cohort of Japanese workers.

Individuals in the lowest versus highest tertile/predefined category of TC in a Japanese working population had a three- to four-fold greater risk of suicide death. Each 10 mg/dl decrement of average TC was associated with an 18% increased chance of suicide death (95% confidence interval, 2–35%). Similar results were found for TC levels at each year.

These results suggest that a low serum TC level in recent past is associated with an increased risk of suicide death.

Vortioxetine is an approved antidepressant that has also demonstrated positive effects on anxiety symptoms in subjects with generalized anxiety disorder (GAD). This post-hoc analysis evaluates the efficacy of vortioxetine in GAD subjects who are working and/or pursuing an education.

In study NCT00744627, 301 GAD subjects were randomized to vortioxetine 5 mg or placebo for 8 weeks. Efficacy measures included the Hamilton Anxiety Rating Scale (HAM–A) total score, response/remission, global functioning (Sheehan Disability Scale [SDS]), and quality of life (Short Form–36 Health Survey). In study NCT00788034, 687 GAD subjects were treated open-label with vortioxetine 5 or 10 mg for 20 weeks, after which subjects in remission were randomized to fixed-dose of vortioxetine (5 or 10 mg) or placebo for at least 24 weeks. The primary endpoint was time to relapse. Analyses were completed in subjects working and/or pursuing an education at study entry and the full analysis set.

In study NCT00744627, the effect of vortioxetine versus placebo on HAM–A total score was –4.3 (p=0.0005) in working subjects (60% of total), while the effect in the total population was –3.8 (p=0.0001). The effect was greatest in subjects in professional (–4.5, p=0.0130) and associate professional positions (–7.6, p=0.0086). Greater effects in terms of response, remission, and the SDS and SF–36 were also observed. In NCT00788034, working subjects (69% of total) randomized to placebo were significantly more likely to relapse than subjects treated with vortioxetine (hazard ratio=2.9; p<0.001), while the hazard ratio in the total population was 2.7 (p<0.0001).

The beneficial effects of vortioxetine on anxiety symptoms, functioning, and quality of life are greater in adults with GAD who are working and/or pursuing an education versus the full GAD study population.
