RESUMO
BACKGROUND: Although vortioxetine demonstrates superior efficacy relative to placebo, there is still a lack of robust evidence to determine whether it offers advantages over commonly prescribed antidepressants for treating major depressive disorder (MDD). Thus, we aimed to perform a systematic review and meta-analysis comparing vortioxetine vs reuptake inhibitors in adults with MDD, analyzing two classes separately: (i) vortioxetine vs SSRIs and (ii) vortioxetine vs SNRIs. METHODS: We searched MEDLINE, Embase, and Cochrane Library databases for randomized controlled trials comparing vortioxetine with SSRIs or SNRIs in adults with a primary diagnosis of MDD following standardized diagnostic criteria. Independent examiners conducted the literature search, study selection, data extraction, and risk of bias assessment. Data were pooled in random-effects analyses. Statistical significance was considered at p<0.05. RESULTS: We included 6 trials (n=478) in the vortioxetine vs SSRIs analysis and 11 (n=4230) in the vortioxetine vs SNRIs analysis. There were no significant differences between vortioxetine and SSRIs/SNRIs in the probability of response, remission, overall dropouts, and dropout due to lack of efficacy. Vortioxetine provided a significantly lower risk of dropout due to adverse events compared with SNRIs, while not significant compared with SSRIs. Vortioxetine did not differ significantly from SNRIs regarding variation in MADRS score post-treatment. In general, vortioxetine exhibited a statistically lower risk of individual adverse events compared with SNRIs, while not significant compared with SSRIs. CONCLUSIONS: Our study reveals that vortioxetine is as effective as SSRIs and SNRIs for treating MDD, with safety equivalent to SSRIs and superior to SNRIs.
RESUMO
BACKGROUND: Cultural traditions attribute to pineal gland an important role for spiritual experiences. Mediumship and spirit possession are cultural phenomena found worldwide which have been described as having dissociative and psychotic-like characteristics, but with nonpathological aspects. A sympathetic activation pattern in response to spirit possession has been reported in some studies, but empirical data on pineal gland is scarce in this context. METHODS: We aimed to investigate pineal gland and pituitary volumes, as well as urinary 6-sulfatoxymelatonin levels in 16 alleged mediums (Medium Group-MG) compared with 16 healthy nonmedium controls (Control Group) (Experiment 1). Furthermore, we aimed to evaluate urinary 6-sulfatoxymelatonin and stress reactivity in GM (n = 10) under different physiological conditions (Experiment 2). RESULTS: In Experiment 1, MG presented higher scores of anomalous experiences, but there were no between-group differences regarding mental health or subjective sleep quality. Similar pineal gland and pituitary volumes were observed between groups. There were no between-group differences in urinary 6-sulfatoxymelatonin collected under equivalent baseline conditions. In Experiment 2, the rise of anxiety and heart rate in response to mediumistic experience was intermediate between a nonstressful control task (reading) and a stressful control task (Trier Social Stress Test-TSST). No significant differences were observed in 6-sulfatoxymelatonin urinary levels between the three conditions. The pattern of stress reactivity during the TSST was normal, but with an attenuated salivary cortisol response. CONCLUSION: The normal neuroimaging and stress reactivity findings in MG contrast with the abnormal results usually observed in subjects with psychotic and dissociative disorders.
