Neuroprotection by cannabidiol and hypothermia in a piglet model of newborn hypoxic-ischemic brain damage Lorena Barataa, Luis Arruza, Maria-José Rodríguez, Esther Aleo, Eva Vierge, Enrique Criado, Elena Sobrino, Carlos Vargas, María Ceprián, Ana Gutiérrez-Rodríguez, William Hind, José Martínez-Orgado Neuropharmacology, 2018. https://doi.org/10.1016/j.neuropharm.2018.11.020 A B S T R A C T Objective : Hypothermia, the gold standard after a hypoxic-ischemic insult, is not beneficial in all treated newborns. Cannabidiol is neuroprotective in animal models of newborn hypoxic-ischemic encephalopathy. This study compared the relative efficacies of cannabidiol and hypothermia in newborn hypoxic-ischemic piglets and assessed whether addition of cannabidiol augments hypothermic neuroprotection. Methods : One day-old HI (carotid clamp and FiO2 10% for 20min) [...]

Mason, Stefan W. Toennes, Kim P.C. Kuypers, and Johannes G. Ramaekers Cannabis and Cannabinoid Research, Volume 4, Number 1, 2019 Mary Ann Liebert, Inc. DOI: 10.1089/can.2018.0047 Abstract Introduction : Synthetic cannabinoid mixtures have been easily accessible for years, leading to the belief that these products were natural and harmless, which contributed to their popularity. Nevertheless, there are many reports of users ending up in hospital due to severe side effects such as tachycardia, aggression, and psychosis. Controlled studies on the effects of synthetic cannabinoids on [...]

Potter, Becky Skidmore, Christine Alexander, Alexander E. Repetski, Vijay Shukla, Bláthnaid McCoy, George A. Wells, Epilepsia, 2018, 1-14. DOI: 10.1111/epi.14608 Summary Objective : To assess the benefits and harms of cannabis‐based products for pediatric epilepsy. Methods : We identified in this living systematic review randomized controlled trials (RCTs) and nonrandomized studies (NRSs) involving children with epilepsy treated with cannabis‐based products. We searched MEDLINE, Embase, PsycINFO, Cochrane Library, and gray literature (April 25, 2018). The primary outcome was seizure freedom; secondary outcomes were seizure frequency (total, ≥50% reduction), quality of life, sleep, status epilepticus, death, gastrointestinal adverse [...]

Jh. hielt Cannabis Einzug in die moderne westliche Medizin und wurde auch als „Freizeitdroge“ genutzt. Aus dieser Zeit stammen detaillierte phänomenologische Bes chreibungen der Effekte. Noch blieb aber der Wirkmechanismus völlig unklar. ● Die erste Hälfte des 20. Jh. ist das „dunkle Zeitalter“ des Cannabis, in dem das Fors chungsinteresse erlahmte. [...]

Lire la suitePsilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer : A randomized double-blind trial GRIFFITHS R.R., JOHNSON M.W., CARDUCCI M.A., UMBRICHT A., RICHARDS W.A., RICHARDS B.D., COSIMANO M.P., KLINEDINST M.A. Journal of Psychopharmacology, 2016, 30, 12, 1181–1197. DOI: 10.1177/0269881116675513 jop.sagepub.com Abstract Cancer patients often develop chronic, clinically significant symptoms of depression and anxiety. Previous studies suggest that psilocybin may decrease depression and anxiety in cancer patients. The effects of psilocybin were studied in 51 cancer patients with life-threatening diagnoses and symptoms of depression and/or anxiety. This randomized, double-blind, cross-over trial investigated the effects of a very low (placebo-like) dose [...]

Doi : 10.1177/0269881117748902 journals.sagepub.com/home/jop Abstract Rationale : Previous research suggests that classical psychedelic compounds can induce lasting changes in personality traits, attitudes and beliefs in both healthy subjects and patient populations. Aim : Here we sought to investigate the effects of psilocybin on nature relatedness and libertarian authoritarian political perspective in patients with treatment-resistant depression (TRD). Methods : This open-label pilot study with a mixed-model design studied the effects of psilocybin on measures of nature relatedness and libertarian– authoritarian political perspective in patients with [...]

Method : Twenty patients with moderate or severe, unipolar, TRD received oral psilocybin (10 and 25 mg, one week apart) in a supportive setting. Personality was assessed at baseline and at 3-month follow-up using the Revised NEO Personality Inventory (NEO-PI-R), the subjective psilocybin experience with Altered State of Consciousness (ASC) scale, and depressive symptoms with QIDS-SR16. Results : [...]
Lire la suiteQuality of Acute Psychedelic Experience Predicts Therapeutic Efficacy of Psilocybin for Treatment-Resistant Depression Leor Roseman, David J. Nutt, Robin L. Carhart-Harris Psychedelic Research Group, Department of Medicine, Imperial College London, London, United Kingdom Frontiers in Pharmacology, 2018, 8, article 974. Doi : 10.3389/fphar.2017.00974 . Introduction : It is a basic principle of the “psychedelic” treatment model that the quality of the acute experience mediates long-term improvements in mental health. In the present paper we sought to test this using data from a clinical trial assessing psilocybin for treatment-resistant depression (TRD). In line with previous reports, we hypothesized that the occurrence and magnitude of Oceanic Boundlessness (OBN) [...]

Bogenschutz and Stephen Ross Frontiers in Pharmacology, 2018, 9, 256 doi: 10.3389/fphar.2018.00256 Abstract : A growing body of evidence shows that existential and spiritual well-being in cancer patients is associated with better medical outcomes, improved quality of life, and serves as a buffer against depression, hopelessness, and desire for hastened death. Historical and recent research suggests a role for psilocybin-assisted psychotherapy in treating cancer-related anxiety and depression. A double-blind controlled trial was performed, where 29 [...]
