Because inflammation is a key process implicated in the pathogenesis of atherosclerosis at all stages, including plaque formation, progression, instability, and rupture, and because colchicine has unique anti-inflammatory properties, this review article summarizes the pathophysiologic mechanisms underpinning inflammation in atherosclerosis and acute coronary syndrome (ACS), outlines anti-inflammatory therapeutic approaches that have been tested thus far, and evaluates the evidence supporting the potential role of colchicine in improving outcomes and reducing cardiovascular morbidity and mortality in patients after ACS. ⋯ Despite promising results in small prospective observational and randomized trials, there is a need for more evidence evaluating the role of colchicine as a secondary preventive agent after ACSs.

With rising rates of cannabis use in the general population and an increasing number of US states legalizing both recreational and medical cannabis use, it is important to be informed about the adverse consequences of cannabinoids. This Commentary provides an overview of the psychiatric effects of plant-based and synthetic cannabinoids, differentiating acute effects from effects associated with persistent use. Cannabinoids produce multiphasic and dose-dependent effects on anxiety, mood, and perception, in addition to impairing cognition and psychomotor function. ⋯ Studies report long-term cannabis exposure has been linked to psychiatric disorders, such as anxiety, psychotic and mood disorders. Limitations to the existing evidence notwithstanding, the plausibility of a causal relationship between cannabinoid exposure and persistent negative psychiatric outcomes, and the potential for long-term brain changes by regular exposure, especially for adolescents, are sufficient to warrant discussions with clinicians and the public. Implications for clinicians who certify, prescribe, or care for patients receiving cannabinoids are discussed, and a case is made for further research to better understand the impact of legalization on public mental health.

Epilepsy is a common neurologic disorder; it is estimated that ∼50million people are affected worldwide. About one third of those patients are drug resistant, defined as failure to stop all seizures despite adequate trials of at least 2 appropriate medications. ⋯ This review discusses the evidence supporting the anticonvulsant properties of cannabis in humans, focusing on cannabidiol. We begin by exploring the early and somewhat anecdotal evidence that was recently replaced by high-quality data from randomized controlled studies, which subsequently led to the US Food and Drug Administration approval of a purified cannabidiol extract for the treatment of 2 highly refractory pediatric epilepsy syndromes (Dravet and Lennox-Gastaut).

Altered Pharmacokinetics in Prolonged Infusions of Sedatives and Analgesics Among Adult Critically Ill Patients: A Systematic Review.
The pharmacokinetic (PK) parameters of many drugs are altered as a consequence of the pathophysiological changes associated with critical illness. The critically ill population presents challenges when titrating infusions of sedatives and analgesics to maintain optimal sedation and pain levels. This systematic review examined the PK data in critically ill adult patients with prolonged infusions (>24 hours) of commonly used sedatives and analgesics to highlight possible altered PK parameters compared with noncritically ill patients. ⋯ These findings show a marked difference in many PK parameters from those reported for noncritically ill patients. Initiatives to improve the delivery of prolonged sedatives and analgesic infusions should be informed by PK parameters (Vdss, context-sensitive t1/2, and elimination t1/2) and data derived from critically ill patients.

ReviewEstablishment of the National Consortium for Regenerative Medicine and National Regenerative Medicine Database in Japan.
With its aim to regain the function of organs that are damaged by illness or injury, regenerative medicine has become the global focus of research. To accelerate the development and establishment of sufficient safety measures in regenerative medicine in Japan, the Pharmaceuticals and Medical Devices Act and the Act on Safety of Regenerative Medicine were enacted in 2014. ⋯ Against this background, the Japanese Society for Regenerative Medicine has been working to establish a national consortium for promoting regenerative medicine and constructing a large-scale clinical data registry, called the National Regenerative Medicine Database. This article aims to introduce the current framework of regenerative medicine in Japan, with a particular focus on the activity for establishment of a national consortium for regenerative medicine and the National Regenerative Medicine Database.
