Real-world approach to managing dysgeusia following the use of esketamine nasal spray: a case report.

Background: Patients with depression who are treated with esketamine nasal spray may commonly experience dysgeusia (bad/metallic/bitter taste) and related side effects such as nausea and vomiting. While pretreatment with antiemetics can mitigate or prevent nausea and vomiting, it may not address dysgeusia as a contributing factor. Alternative interventions could help to manage vomiting due to dysgeusia following administration of esketamine nasal spray in those patients who are affected.

Effort-based decision-making in major depressive disorder: a translational model of motivational anhedonia.

Anhedonia is a core feature of major depressive disorder (MDD), but the precise nature of anhedonic symptoms is unknown. Whereas anhedonia has traditionally been viewed as a deficit in the experience of pleasure, more recent evidence suggests that reduced anticipation and motivation may also be a core feature of this symptom. Here, we provide data from a study in MDD patients and healthy controls using a translational measure of reward motivation, the Effort Expenditure for Rewards Task (EEfRT or "effort").

A randomized open comparison of long-acting injectable risperidone and treatment as usual for prevention of relapse, rehospitalization, and urgent care referral in community-treated patients with rapid cycling bipolar disorder.

Objective: To compare adjunctive long-acting injectable risperidone plus treatment as usual (RLAI+TAU) versus TAU alone for relapse, rehospitalization, and urgent care events in patients with bipolar disorder in routine care settings.

Methods: This was a 12-month randomized open comparison of RLAI+TAU (n = 20) and TAU alone (n = 25) in adults with rapid cycling, Mini International Neuropsychiatric Interview-confirmed bipolar I/II disorder and 4 or more illness relapses in the preceding 12 months. Clinical outcome was assessed every 2 weeks using the Longitudinal Interval Follow-up Evaluation instrument.
