Psychedelic clinics in Ontario are promoting psilocybin and other psychedelics for an astonishing 47 distinct medical conditions, often with insufficient scientific backing. An analysis of 10 clinic websites revealed only 2 out of 10 described potential risks. While 29 studies were cited for these medical prescriptions, most offered low-to-moderate "level 4" evidence, like case-series. This raises concerns for mental health patients seeking medicine, underscoring the need for transparent, high-quality information regarding psychedelic treatments in family medicine and psychiatry.

Abstract

Psychedelics, including ketamine, 3,4-Methyl enedioxy methamphetamine (MDMA), and psilocybin, have gained attention for their potential therapeutic...

Expert recommendations for Germany’s integration of psychedelic-assisted therapy

BMC Medical Education  – October 24, 2024

Summary

Australia has already approved MDMA and psilocybin for mental health, highlighting Europe's urgent need to advance medical education in psychedelic-assisted therapy. With USA trials in Phase III, Germany is poised to lead Europe in developing robust frameworks for integrating innovative Psychedelics and Drug Studies into Medicine. This includes defining ethical Psychotherapy Techniques and Applications, practitioner training, and regulatory oversight. Such infrastructure development aims to ensure proficient care, potentially reclaiming Europe's historical lead in Psychology and psychiatric innovation, as seen with Switzerland's 2014 reintroduction of MDMA and LSD for restricted medical use.

Abstract

As clinical trials for psychedelics move into phase III in the USA, Europe must address its lag in integrating professional education around psyche...

Psilocybin Reduces Grooming in the SAPAP3 Knockout Mouse Model of Compulsive Behaviour

OpenAlex  – October 24, 2024

Summary

A single 1 mg/kg dose of Psilocybin dramatically reduced obsessive compulsive-like behaviors for up to a week in male knockout mice, a key model in Psychology for compulsive disorders. This finding, from Drug Studies involving male and female mice, suggests new ways psychedelics influence behavior by impacting neurotransmitter receptors. It also reduced grooming in female mice. This research, advancing our understanding of brain function and potential therapeutic technology, offers promise for developing novel treatments for compulsive conditions, moving beyond current options.

Abstract

Abstract Psilocybin is a serotonergic psychedelic compound which shows promise for treating compulsive behaviours. This is particularly pertinent a...

Effect of different doses of esketamine on the median effective concentration of propofol for inhibiting body movement during hysteroscopy.

Scientific reports  – October 24, 2024

Summary

Combining anesthetics strategically can lead to better patient outcomes. When esketamine is paired with propofol during hysteroscopy procedures, doctors can use less propofol while still effectively preventing patient movement. Higher doses of esketamine (0.3 mg/kg) allowed for a 20% reduction in required propofol levels, while also reducing post-operative anxiety and depression scores.

Abstract

The objective of this study is to investigate the effects of various doses of esketamine on the median effective concentration (EC50) of propofol r...

Ayahuasca drinking using a two-bottle choice procedure in male mice.

Scientific reports  – October 23, 2024

Summary

Male mice given a choice between water and Ayahuasca showed fascinating drinking patterns: frequent access led to preference for the psychedelic brew, while longer breaks between drinks resulted in aversion. Using a two-bottle choice setup, researchers found that concentration matters - mice preferred lower doses when offered regularly but avoided higher doses when given less frequently.

Abstract

Ayahuasca has been proposed as a treatment for substance use disorders. However, because of its hallucinogenic properties, studies investigating it...

Rapid Effects of MDMA Administration on Self-Reported Personality Traits and Affect State: A Randomized, Placebo-Controlled Trial in Healthy Adults.

Journal of psychoactive drugs  – October 23, 2024

Summary

In a groundbreaking clinical trial, MDMA showed promising effects on personality traits and emotional well-being. Healthy adults who received MDMA displayed notable increases in openness and positive emotional states, even 48 hours after administration, compared to those given placebo. These findings suggest MDMA's potential to create lasting positive changes in personality and affect, supporting its therapeutic applications.

Abstract

3,4-methylenedioxymethamphetamine (MDMA) assisted therapy has been shown to be a safe and effective treatment for PTSD and emerging research sugges...

Improvement in pain by using lidocaine combined with esketamine in elderly patients receiving local anaesthesia for percutaneous kyphoplasty: a randomized controlled study.

BMC anesthesiology  – October 23, 2024

Summary

Adding esketamine to local anaesthesia dramatically improves pain control in older patients undergoing spine procedures. When combined with lidocaine during percutaneous kyphoplasty, this adjuvant medication achieved 100% patient satisfaction compared to just 48% with standard treatment. The combination proved especially effective for elderly patients, providing better pain relief and more stable vital signs throughout the procedure, all without significant side effects.

Abstract

Elderly patients often experience severe pain during percutaneous kyphoplasty under local anaesthesia. The aim of this work was to evaluate the eff...
