Background: Statins and selective serotonin reuptake inhibitors (SSRIs) have beneficial effects on health outcomes in the general population. Their effect on survival in debilitated nursing home residents is unknown.

Objectives: To assess the relationships between statins, SSRIs, and survival of nursing home residents.

Methods: Baseline patient characteristics, including chronic medications, were recorded. The association of 5-year survival with different variables was analyzed. A sub-group analysis of survival was performed according to baseline treatment with statins and/or SSRIs.

Results: The study comprised 993 residents from 6 nursing homes. Of them, 285 were males (29%), 750 (75%) were fully dependent, and 243 (25%) were mobile demented. Mean age was 85 ± 7.6 years (range 65–108). After 5 years follow-up, the mortality rate was 81%. Analysis by sub-groups showed longer survival among older adults treated with only statins (hazard ratio [HR] for death 0.68, 95% confidence intervals [95%CI] 0.49–0.94) or only SSRIs (HR 0.6, 95%CI 0.45–0.81), with the longest survival among those taking both statins and SSRIs (HR 0.41, 95%CI 0.25–0.67) and shortest among residents not taking statins or SSRIs (P < 0.001). The survival benefit remained significant after adjusting for age and after conducting a multivariate analysis adjusted for sex, functional status, body mass index, mini-mental state examination, feeding status, arrhythmia, diabetes mellitus, chronic kidney disease, and hemato-oncological diagnosis.

Conclusion: Treatment with statins and/or SSRIs at baseline was associated with longer survival in debilitated nursing home residents and should not be deprived from these patients, if medically indicated.

The relevance of central neurotransmission to aggressive and impulsive behavior has become more evident due to extensive research in humans and in animals. Among other findings, there are abundant data relating low serotonergic activity – as measured by low cerebrospinal fluid 5-hydroxyindolacetic acid, and a blunted response of prolactin to fenfluramine – to impulsive behavior. Many studies on testosterone activity show a relation between high plasma levels and a tendency towards aggression. It is hypothesized that the interaction between low serotonin and high testosterone levels in the central nervous system has a significant effect on the neural mechanisms involved in the expression of aggressive behavior. It seems that testosterone modulates serotonergic receptors activity in a way that directly affects aggression, fear and anxiety. Our survey reviews the main findings on serotonin, testosterone and the possible interaction between them with regard to these behavioral phenomena.
