Objectives: Calcitonin, a neuropeptide, has been shown in preliminary double-blind trials to reduce agitation in patients with acute mania. Given that it has effects similar to those of lithium and anticonvulsants on modulation of second-messenger signaling pathways and stabilization of neuronal membranes, this study examined the efficacy of calcitonin nasal spray in treating acute manic symptoms in patients with treatment-resistant mania using a double-blind, placebo-controlled design.
Methods: A total of 46 hospitalized patients experiencing either a manic or a mixed episode, who were refractory to treatment with adequate doses of either a mood stabilizer or an antipsychotic, or a mood stabilizer/antipsychotic combination, and had a score of ≥16 on the Young Mania Rating Scale (YMRS), were randomized to receive adjunctive nasal calcitonin 200 IU (n = 24) or saline (n = 22) spray for three weeks. The primary efficacy measure was the change in YMRS scores using the last observation carried forward (LOCF) method.
Results: The clinical and demographic characteristics were similar between the groups. Patients had a mean YMRS score of 26 in the placebo group and a mean score of 25 in the calcitonin group. There were no significant differences in YMRS scores or percentage responders at three weeks between patients who received calcitonin and those who received placebo. There were also no significant differences in change scores on any other scales. Few patients experienced any adverse events.
Conclusions: This study does not support the use of nasal calcitonin in the treatment of treatment-resistant mania.

Objective: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social communication differences and restricted interests. One proposed biologic mechanism underlying ASD is oxidative stress, leading to the clinical use of glutathione based on anecdotal reports of improved behavior in autistic children. In this pilot study, we tested this observation using a randomized clinical trial format to collect preliminary data on glutathione safety and efficacy.

Perception integrates external sensory signals with internal predictions that reflect prior knowledge about the world. Previous research suggests that this integration is governed by slow alternations between an external mode, driven by sensory signals, and an internal mode, shaped by prior knowledge. Using a double-blind, placebo-controlled, cross-over experiment in healthy human participants, we investigated the effects of the N-Methyl-D-aspartate receptor (NMDAR) antagonist S-ketamine on the balance between external and internal modes.

Background: Attentional bias to pain-related information has been implicated in pain chronicity. To date, research investigating attentional bias modification training (ABMT) procedures in people with chronic pain has found variable success, perhaps because training paradigms are typically repetitive and monotonous, which could negatively affect engagement and adherence. Increasing engagement through the gamification (ie, the use of game elements) of ABMT may provide the opportunity to overcome some of these barriers.

Serotonin (5-HT) is integral to signalling in areas of the brainstem controlling ventilation and is involved in central chemoreception. Selective serotonin reuptake inhibitors (SSRIs), used to effectively increase 5-HT concentrations, are commonly prescribed for depression. The effects of SSRIs on the control of breathing and the potential influence of cerebral blood flow (CBF) have not been directly assessed.

Type 2 diabetes (T2D) is a metabolic disease associated with cardiovascular dysfunction. The myocardium preferentially uses ketones over free fatty acids as a more energy efficient substrate. The primary aim was to assess the effects of ketone monoester (K) ingestion on cardiac output index ().
