Unlike traditional antidepressants, they can be used in combination with non-selective monoamine oxidase inhibitors (NS-MAOI) without the risk of serotonergic syndrome. However, potential sympathomimetic synergy may lead to elevated blood pressure (BP). This series investigates whether cardiovascular parameters (heart rate, systolic [SP], and diastolic [DP] pressures) increase during ESK sessions and whether the ESK+NS-MAOI combination is associated with BP elevations.We collected cardiovascular parameters for ESK sessions conducted between 2018 and 2022. These parameters were measured at baseline and every 30 min for 2 h. Patients were categorized into two non-equivalent groups: those receiving ESK alone and those receiving ESK+NS-MAOI. A Bayesian random model was used to estimate the evolution of these parameters, while a Bayesian hierarchical model assessed factors contributing to BP elevation.ESK sessions (n=193), of which 116 involved NS-MAOI, were performed in 13 patients. SP, DP, and heart rate showed peak increases during sessions, but these changes were not clinically significant (SP+8.68 mmHg, DP+6.57 mmHg, and heart rate+3.5 bpm). No significant differences were found between the ESK-alone and ESK+NS-MAOI groups. The combination was not identified as a factor linked to BP elevations.These findings align with previous research on ketamine derivatives and suggest minimal peripheric sympathomimetic synergy with NS-MAOI. Bayesian models were used to account for biases intrinsically related to these ecological data and provide a foundation for future open adversarial collaborations.

Given the complicated procedure of the dex/CRH-test, this study aimed to develop a genetic variants-based alternative approach to predict the outcome of the dex/CRH-test in acute depression.Using data of a representative cohort of 352 patients with severe depression participating in the dex/CRH-test, a genome-wide interaction analysis was performed starting with an anchor single nucleotide polymorphism located in the upstream transcriptional region of the human V1b-receptor gene to predict the adrenocorticotropic hormone (ACTH) response to this test. A probabilistic neural-network-algorithm was used to develop the optimal prediction model.Overall prediction accuracy for correctly identifying high ACTH responders in the dex/CRH-test was 93.5% (sensitivity 90%; specificity 95%).
