Control Group Outcomes in Trials of Psilocybin, SSRIs, or Esketamine for Depression

JAMA Network Open  – July 30, 2025

Summary

Psilocybin’s impressive antidepressant effects for Major depressive disorder may be over-estimated. A meta-analysis of 17 Randomized controlled trials (4960 patients) comparing Psilocybin, Serotonin reuptake inhibitors like Fluoxetine, and esketamine for Treatment of Major Depression and Treatment-resistant depression, revealed control groups in psilocybin clinical trials improved less. Their depression rating scale scores improved by an effect size of 0.50, versus 1.00 for antidepressant SSRI controls and 1.12 for esketamine controls. This finding is crucial for Psychiatry and Psychedelics and Drug Studies.

Abstract

Importance Psilocybin has demonstrated rapid and sustained antidepressant efficacy, with acute-phase effect sizes often more than double those for ...

Ketamine's impact on mood after day-case surgery and its relation to obesity: a randomised controlled trial in women undergoing fractional curettage.

BMC women's health  – July 30, 2025

Summary

A randomised controlled trial involving women undergoing fractional curettage for day-case surgery revealed a surprising finding: while a single dose of Ketamine alongside Propofol and Fentanyl didn't universally elevate total mood scores measured by the POMS questionnaire, it significantly improved emotional recovery specifically for obese women. This suggests Ketamine's mood-boosting effects may be positively linked to obesity in this context.

Abstract

Several studies have shown that ketamine has an effect on mood and depression in the perioperative context; however, little is known about ketamine...

Low-dose esketamine combined with propofol versus fentanyl-propofol for preventing hypoxemia during gastroscopy sedation in high-altitude residents: a randomized controlled trial.

BMC anesthesiology  – July 30, 2025

Summary

A key challenge in medical procedures at high altitude is preventing low blood oxygen. For gastroscopy requiring deep sedation, a new approach combining esketamine with propofol significantly reduced hypoxemia incidence (8.75% vs. 32.5%) compared to a standard fentanyl-propofol mix. This regimen also improved patient stability, lowered propofol dosage, and sped up recovery for high-altitude residents, proving a safer, more effective option.

Abstract

The aim of this study is to evaluate the efficacy and safety of low-dose esketamine combined with propofol in reducing the incidence of hypoxemia d...

Examining the Dose-Response Effects of Mindfulness Meditation Interventions on Well-Being: Protocol for a Randomized Controlled Trial.

JMIR research protocols  – July 29, 2025

Understanding the ideal "dose" of mindfulness meditation for boosting well-being is crucial. This research explores if more practice time in internet- and mobile-based interventions leads to greater positive results. Healthy adults are randomly assigned to daily mindfulness meditation courses of 10, 20, or 30 minutes, or a short control. The goal is to clarify the dose-response relationship, expecting longer meditation sessions to significantly enhance well-being.

Abstract

Mindfulness meditation has demonstrated modest benefits for mental health and well-being, although the relationship between practice dose and outco...

Electrophysiological effects of psilocybin co-administered with midazolam

OpenAlex  – July 29, 2025

Summary

Imagine experiencing a profound psychedelic journey without memory of it. A pilot study in **psychedelics and drug studies** gave participants 25 mg of psilocybin—an **alkaloid** from **chemical synthesis**—with a sedative. This allowed the full psychedelic experience, blunting recall. Brain activity showed distinct patterns: initially, increased beta power; then, as psilocybin's **neurotransmitter receptor influence on behavior** grew over six hours, increased brain complexity and altered power. Psilocybin's effects persist despite memory suppression, supporting mechanistic studies.

Abstract

Abstract The serotonergic psychedelic psilocybin induces neural plasticity and profoundly alters consciousness. The benzodiazepine midazolam blunts...

Exploring Esketamine's Therapeutic Role for Perinatal Depression via TASK-1 Tandem Pore Potassium Channels.

ACS chemical neuroscience  – July 29, 2025

Summary

Remarkably, a new approach significantly lowers depression scores in new mothers. It investigates how esketamine works, specifically targeting the TWIK-related acid-sensitive K+ channel 1 channel. Clinical trials with 298 women and lab studies confirmed its benefits. This treatment effectively combats perinatal depression by reducing neuroinflammation and enhancing synaptic plasticity, mediated by the TWIK-related acid-sensitive K+ channel 1 channel. This suggests esketamine is a powerful therapeutic avenue, offering a clear path to improved mental well-being.

Abstract

This research focuses on the promising use of esketamine in perinatal depression, a widespread disorder impacting postpartum women's mental health....

Psilocybin in the treatment of eating disorders: a systematic review of the literature and registered clinical trials

Eating and Weight Disorders - Studies on Anorexia Bulimia and Obesity  – July 29, 2025

Summary

With Fluoxetine the only pharmacological treatment approved for Bulimia Nervosa, and no drugs for other eating disorders like Anorexia Nervosa, new options are crucial. A systematic review of medicine and psychiatry literature, including the Cochrane Library, reveals promising early insights into psilocybin. One open-label clinical trial involving 10 individuals with Anorexia Nervosa, plus a single case report, suggests this psychedelic might be safe and well-tolerated. Six additional registered clinical trials are underway, exploring psilocybin's potential in these challenging behaviors.

Abstract

Abstract Background Fluoxetine remains the only pharmacological treatment approved for Bulimia Nervosa, and no other drugs have been approved for e...
