Psilocybin-Assisted Therapy for Physician Well-Being and Burnout: Feasibility, Safety, Clinical Effectiveness and Biomarkers of Response [PAT-B (Psilocybin-Assisted Therapy for Physician Well-Being and Burnout)]

Through an open-label study involving a small group of UCSD physicians experiencing burnout, the investigators will evaluate the feasibility, safety, and preliminary effectiveness of PAT to reduce burnout symptoms. Physician burnout is a critical issue. Research shows that physician burnout is increasing, that physicians suffer higher rates of burnout than t...

Divergent changes in perturbation-induced brain reconfiguration following depression treatment with psilocybin and escitalopram

A central challenge in neuroscience is understanding how the human brain is organised to support optimal functioning and adaptability. One approach to characterise complex brain dynamics is by artificially perturbing whole-brain models. Here, we asked whether whole-brain organisation under perturbation in major depressive disorder (MDD) changes after interve...

Anthracaurisin A─Discovery of a Cytotoxic -Sesquiterpene Dimer from Patagonian.

Fungal natural products, also called secondary metabolites (SMs), continue to inspire chemists and drug development. Around 30,000 fungal SMs are known, mainly from filamentous fungi of the phylum Ascomycota. Only 5% of all fungal species are described today, and even fewer have been cultured or chemically screened, which makes fungi an untapped reservoir fo...

Acute Effects of MDMA Co-administration on the Response to Psilocybin in Healthy Subjects

The acute subjective effects of serotonin (5-HT)2A receptor stimulation with psilocybin in humans are mostly positive. However, negative effects such as anxiety, paranoid thinking, or loss of trust towards other people are common effects, depending on the dose administered, the personality traits of the person consuming it (set), or the environment in which ...

The intersection between psychedelics and schizophrenia spectrum disorders: Reevaluating risk and therapeutic potential.

In the past decade, interest in studying psychedelic compounds as potential therapeutic agents has resurged. These studies carefully exclude individuals at risk for developing psychotic symptoms in response to psychedelic use. Given the potential for psychedelics to be established as treatments in psychiatry, it is important to more robustly understand their...

Novel approaches in depression treatment: from rapid-acting antidepressants to personalized interventions.

Major depressive disorder (MDD) and treatment-resistant depression (TRD) are prevalent and debilitating conditions. Over 50% of patients have inadequate response to first-line serotonergic antidepressants and are left with suboptimal treatment options. Rapid-acting and individually tailored treatments for MDD remain major unmet needs. This review discusses p...

Multi-metric evaluations of acute psychedelic effects on fMRI brain entropy.

A prominent theory of psychedelics is that they increase brain entropy. Thirteen studies have evaluated psychedelic effects on fMRI brain entropy, each applying a distinct measure. Here we evaluated these metrics in an independent 28-participant healthy cohort with 121 pre- and post-psilocybin fMRI scans. We assessed relations between brain entropy and objec...
