Driving under the influence of drugs (DUID) is a worldwide problem. Several countries adopted DUID legislations which prove their deterrent effect and impact on road safety. However, use of new psychoactive substances (NPS) and prescription drugs is not known as the applied roadside screening tests are not yet adapted for these compounds. In this study, 558 blood samples obtained during roadside controls in Belgium (January to August 2015) after a positive Drugwipe 5S® test and 199 oral fluid (OF) samples obtained from negatively screened test pads were analyzed...

BACKGROUND: Ketamine is an anesthetic commonly used in low-income countries and has recently been shown to be effective for treatment-resistant depression. However, the illicit manufacturing, trafficking, and nonmedical use of ketamine are increasing globally, and its illicit use poses major public health challenges in many countries. OBJECTIVES: To review the nonmedical use of ketamine in selected countries and its regulatory control. METHODS: We conducted a review of literature identified from searches of the China National Knowledge Infrastructure (CNKI) (1979-2016) and PubMed databases, supplemented by additional references identified by the authors...

Alterations of the normal redox state can be found in all stages of schizophrenia, suggesting a key role for oxidative stress in the etiology and maintenance of the disease. Pharmacological blockade of N-methyl-D-aspartic acid (NMDA) receptors can disrupt natural antioxidant defense systems and induce schizophrenia-like behaviors in animals and healthy human subjects. Perinatal administration of the NMDA receptor (NMDAR) antagonist ketamine produces persistent behavioral deficits in adult mice which mimic a range of positive, negative, and cognitive symptoms that characterize schizophrenia...

Schizophrenia is a chronic and devastating disease with an overall lifetime risk of 1%. While positive symptoms of schizophrenia such as hallucinations and delusions are reduced by antipsychotic medication based on the inhibition of type 2 dopaminergic receptors (D2R), negative symptoms (e.g. reduced motivation) and cognitive symptoms (e.g. impaired working memory) of schizophrenia are not effectively treated by current medication. This dichotomy might arise in part because of our limited understanding of the pathophysiology of negative and cognitive symptoms in schizophrenia...

Imbalance in neural excitation and inhibition is associated with behavioral dysfunction in individuals with schizophrenia and at risk for this illness. We examined whether targeting increased neural activity with the antiepileptic agent, levetiracetam, would benefit memory performance in a preclinical model of schizophrenia that has been shown to exhibit hyperactivity in the hippocampus. Adult rats exposed to ketamine subchronically during late adolescence showed impaired hippocampal-dependent memory performance...

REVIEW
Brendan Carvalho, Alexander J Butwick
Effective pain management should be a key priority in women undergoing cesarean delivery. Suboptimal perioperative pain management is associated with chronic pain, greater opioid use, delayed functional recovery, impaired maternal-fetal bonding, and increased postpartum depression. Severe acute postoperative pain is also strongly associated with persistent pain after cesarean delivery. Multimodal analgesia is the core principle for cesarean delivery pain management. The use of neuraxial morphine and opioid-sparing adjuncts such as scheduled nonsteroidal anti-inflammatory medications and acetaminophen is recommended for all women undergoing cesarean delivery with neuraxial anesthesia unless contraindicated...

The effects of general anesthetics on inducing neuronal apoptosis during early brain development are well-documented. However, since physiological apoptosis also occurs during this developmental window, it is important to determine whether anesthesia-induced apoptosis targets the same cell population as physiological apoptosis or different cell types altogether. To provide an adequate plane of surgery, ketamine was co-administered with dexmedetomidine. The apoptotic neurons in the mouse primary somatosensory cortex (S1) were quantitated by immunohistochemistry...

The goal of this study was to generate reference intervals for echocardiographic variables in a population of clinically normalgeriatric rhesus macaques (Macaca mulatta). To do this, we studied 51 animals (age, 18-29 y; weight, 5.24-17.04 kg). Thenormal values for cardiac indices, including geometry and systolic and diastolic function, were determined by 2D, M-mode,spectral Doppler, and tissue Doppler echocardiography under ketamine hydrochloride sedation. Statistical correlations betweenthe echocardiographic parameters and age, body weight, sex, and heart rate were investigated...

BACKGROUND: Ketamine has been used as part of the multimodal analgesia technique in the acute perioperative period. The effect of perioperative intravenous small-dose ketamine on the quality of recovery from the patient point-of-view has not been assessed. We hypothesized that low-dose ketamine would enhance recovery following laparoscopic cholecystectomy under total intravenous anesthesia. METHODS: One hundred thirty five patients undergoing laparoscopic cholecystectomy were enrolled in this randomized, double-blind placebo-controlled trial...

The senescence-accelerated mouse prone 8 (SAMP8) model is characterized by accelerated, progressive cognitive decline as well as Alzheimer's disease (AD)-like neurodegenerative changes, and resembles the etiology of multicausal, sporadic late-onset/age-related AD in humans. Our aim was to find whether these AD-like pathological features, together with the cognitive deficits present in the SAMP8 strain, are accompanied by disturbances in cortical network activity with respect to control mice (SAM resistance 1, SAMR1) and, if so, how the alterations in cortical activity progress with age...

Ketamine is widely used in animals and humans as a systemic anesthetic. Although several immune-modulatory functions of ketamine have been reported, the effects of ketamine on the differentiation of Th17 cell are unknown. We found that ketamine significantly diminished the frequency of IL-17-producers among CD4+ T cells stimulated under Th17-skewing conditions. Mechanistic studies showed that ketamine had little effect on the production of Th17-inducing cytokines by dendritic cells and the proliferation of T cells in response to anti-CD3; however it significantly hampered IL-21 expression as well as STAT3 phosphorylation in T cells upon IL-6 stimulation...

The weeks/months it takes for traditional antidepressants to act pose an obstacle in the management of depression. Ketamine's prompt and sustained antidepressant effects constitute a major advance. Multiple studies implicate glutamatergic signaling to protein synthesis machinery and synapse formation in ketamine's antidepressant effects. Here we review evidence linking ketamine to glutamate receptor subtypes and protein homeostasis. We describe a signaling cascade wherein nitric oxide drives the formation of a ternary protein complex comprised of glyceraldehyde 3-phosphate dehydrogenase, seven in absentia homolog 1, and Ras homolog enriched in brain downstream of the glutamate N-methyl-D-aspartate receptor...

Psychosis is a chronic neuropsychiatric disorder that affects millions of individuals worldwide and impairs the quality of life and productivity of the patients. The clinical efficacy of antipsychotic drugs has been compromised by adverse effects, relapse, and therapeutic failures, thus necessitating search for alternative agents. Methyl jasmonate (MJ) is a bioactive compound reported to have beneficial effects in various neurological disorders. This study was undertaken to investigate the antipsychotic-like effects of MJ in mice...

BACKGROUND AND OBJECTIVES: Complex regional pain syndrome is a challenging disease to treat. Recently, a mouse fracture model of complex regional pain syndrome has been developed that has many signs of the clinical syndrome. However, many aspects of the sensory neuron biochemistry and behavioral and pharmacological characterization of this model remain to be clarified. METHODS: Mice were randomly assigned to fracture/cast or control (naive) groups. Fracture/cast mice underwent a closed distal tibia facture, with hindlimb wrapped in casting tape for 3 weeks...
